Indian J Psychiatry 2020;62:337-8Celebrity suicide is antabuse 250mg online one of the highly publicized events in our country. Indians got a glimpse of this following an unfortunate incident where a popular Hindi film actor died of suicide. As expected, the antabuse 250mg online media went into a frenzy as newspapers, news channels, and social media were full of stories providing minute details of the suicidal act.

Some even going as far as highlighting the color of the cloth used in the suicide as well as showing the lifeless body of the actor. All kinds of personal details were dug up, and speculations and hypotheses became the order of the day in the next few days that followed. In the process, reputations of many people associated with the actor were besmirched and their private and personal details were freely and antabuse 250mg online blatantly broadcast and discussed on electronic, print, and social media. We understand that media houses have their own need and duty to report and sensationalize news for increasing their visibility (aka TRP), but such reporting has huge impacts on the mental health of the vulnerable population.The impact of this was soon realized when many incidents of copycat suicide were reported from all over the country within a few days of the incident. Psychiatrists suddenly started getting distress calls antabuse 250mg online from their patients in despair with increased suicidal ideation.

This has become a major area of concern for the psychiatry community.The Indian Psychiatric Society has been consistently trying to engage with media to promote ethical reporting of suicide. Section 24 antabuse 250mg online (1) of Mental Health Care Act, 2017, forbids publication of photograph of mentally ill person without his consent.[1] The Press Council of India has adopted the guidelines of World Health Organization report on Preventing Suicide. A resource for media professionals, which came out with an advisory to be followed by media in reporting cases of suicide. It includes points forbidding them from putting stories in prominent positions and unduly repeating them, explicitly describing the method used, providing details about the site/location, using sensational headlines, or using photographs and video footage of the incident.[2] Unfortunately, the advisory seems to have little effect in the aftermath of celebrity suicides. Channels were full of antabuse 250mg online speculations about the person's mental condition and illness and also his relationships and finances.

Many fictional accounts of his symptoms and illness were touted, which is not only against the ethics but is also contrary to MHCA, 2017.[1]It went to the extent that the name of his psychiatrist was mentioned and quotes were attributed to him without taking any account from him. The Indian Psychiatric Society antabuse 250mg online has written to the Press Council of India underlining this concern and asking for measures to ensure ethics in reporting suicide.While there is a need for engagement with media to make them aware of the grave impact of negative suicide reporting on the lives of many vulnerable persons, there is even a more urgent need for training of psychiatrists regarding the proper way of interaction with media. This has been amply brought out in the aftermath of this incident. Many psychiatrists and mental health professionals antabuse 250mg online were called by media houses to comment on the episode. Many psychiatrists were quoted, or “misquoted,” or “quoted out of context,” commenting on the life of a person whom they had never examined and had no “professional authority” to do so.

There were even stories with byline of a psychiatrist where the content provided was not only unscientific but also way beyond the expertise of a psychiatrist. These types of viewpoints perpetuate stigma, myths, and “misleading concepts” about psychiatry and are detrimental to the antabuse 250mg online image of psychiatry in addition to doing harm and injustice to our patients. Hence, the need to formulate a guideline for interaction of psychiatrists with the media is imperative.In the infamous Goldwater episode, 12,356 psychiatrists were asked to cast opinion about the fitness of Barry Goldwater for presidential candidature. Out of 2417 respondents, 1189 psychiatrists reported him to be mentally unfit while none had actually examined him.[3] This led to the formulation of “The Goldwater Rule” by the American Psychiatric Association in 1973,[4] but we have witnessed the same phenomenon at the time of presidential candidature of Donald antabuse 250mg online Trump.Psychiatrists should be encouraged to interact with media to provide scientific information about mental illnesses and reduction of stigma, but “statements to the media” can be a double-edged sword, and we should know about the rules of engagements and boundaries of interactions. Methods and principles of interaction with media should form a part of our training curriculum.

Many professional societies have guidelines and resource books for interacting with media, and psychiatrists should antabuse 250mg online familiarize themselves with these documents. The Press Council guideline is likely to prompt reporters to seek psychiatrists for their expert opinion. It is useful for them to have a template ready with suicide rates, emphasizing multicausality of suicide, role of mental disorders, as well as help available.[5]It is about time that the Indian Psychiatric Society formulated its own guidelines laying down the broad principles and boundaries governing the interaction of Indian psychiatrists with the media. Till then, it is desirable to be guided by the following broad principles:It should be assumed that no statement goes “off the record” as the media person is most likely recording the interview, and we should also record any such antabuse 250mg online conversation from our endIt should be clarified in which capacity comments are being made – professional, personal, or as a representative of an organizationOne should not comment on any person whom he has not examinedPsychiatrists should take any such opportunity to educate the public about mental health issuesThe comments should be justified and limited by the boundaries of scientific knowledge available at the moment.

However, it has always been accused of being a coercive, unethical, and dangerous modality of treatment.

The dangerousness of ECT has been mainly attributed to its claimed ability to cause brain damage. This narrative review aims to provide an update of the evidence with regard to whether the practice of ECT is associated with damage to the brain. An accepted definition of brain damage remains elusive. There are also ethical and technical problems in designing studies that look at this question specifically. Thus, even though there are newer technological tools and innovations, any review attempting to answer this question would have to take recourse to indirect methods.

These include structural, functional, and metabolic neuroimaging. Body fluid biochemical marker studies. And follow-up studies of cognitive impairment and incidence of dementia in people who have received ECT among others. The review of literature and present evidence suggests that ECT has a demonstrable impact on the structure and function of the brain. However, there is a lack of evidence at present to suggest that ECT causes brain damage.Keywords.

Adverse effect, brain damage, electroconvulsive therapyHow to cite this article:Jolly AJ, Singh SM. Does electroconvulsive therapy cause brain damage. An update. Indian J Psychiatry 2020;62:339-53 Introduction Electroconvulsive therapy (ECT) as a modality of treatment for psychiatric disorders has existed at least since 1938.[1] ECT is an effective modality of treatment for various psychiatric disorders. However, from the very beginning, the practice of ECT has also faced resistance from various groups who claim that it is coercive and harmful.[2] While the ethical aspects of the practice of ECT have been dealt with elsewhere, the question of harmfulness or brain damage consequent upon the passage of electric current needs to be examined afresh in light of technological advances and new knowledge.[3]The question whether ECT causes brain damage was reviewed in a holistic fashion by Devanand et al.

In the mid-1990s.[4],[5] The authors had attempted to answer this question by reviewing the effect of ECT on the brain in various areas – cognitive side effects, structural neuroimaging studies, neuropathologic studies of patients who had received ECT, autopsy studies of epileptic patients, and finally animal ECS studies. The authors had concluded that ECT does not produce brain damage.This narrative review aims to update the evidence with regard to whether ECT causes brain damage by reviewing relevant literature from 1994 to the present time. Framing the Question The Oxford Dictionary defines damage as physical harm that impairs the value, usefulness, or normal function of something.[6] Among medical dictionaries, the Peter Collins Dictionary defines damage as harm done to things (noun) or to harm something (verb).[7] Brain damage is defined by the British Medical Association Medical Dictionary as degeneration or death of nerve cells and tracts within the brain that may be localized to a particular area of the brain or diffuse.[8] Going by such a definition, brain damage in the context of ECT should refer to death or degeneration of brain tissue, which results in the impairment of functioning of the brain. The importance of precisely defining brain damage shall become evident subsequently in this review.There are now many more tools available to investigate the structure and function of brain in health and illness. However, there are obvious ethical issues in designing human studies that are designed to answer this specific question.

Therefore, one must necessarily take recourse to indirect evidences available through studies that have been designed to answer other research questions. These studies have employed the following methods:Structural neuroimaging studiesFunctional neuroimaging studiesMetabolic neuroimaging studiesBody fluid biochemical marker studiesCognitive impairment studies.While the early studies tended to focus more on establishing the safety of ECT and finding out whether ECT causes gross microscopic brain damage, the later studies especially since the advent of advanced neuroimaging techniques have been focusing more on a mechanistic understanding of ECT. Hence, the primary objective of the later neuroimaging studies has been to look for structural and functional brain changes which might explain how ECT acts rather than evidence of gross structural damage per se. However, put together, all these studies would enable us to answer our titular question to some satisfaction. [Table 1] and [Table 2] provide an overview of the evidence base in this area.

Structural and Functional Neuroimaging Studies Devanand et al. Reviewed 16 structural neuroimaging studies on the effect of ECT on the brain.[4] Of these, two were pneumoencephalography studies, nine were computed tomography (CT) scan studies, and five were magnetic resonance imaging (MRI) studies. However, most of these studies were retrospective in design, with neuroimaging being done in patients who had received ECT in the past. In the absence of baseline neuroimaging, it would be very difficult to attribute any structural brain changes to ECT. In addition, pneumoencephalography, CT scan, and even early 0.3 T MRI provided images with much lower spatial resolution than what is available today.

The authors concluded that there was no evidence to show that ECT caused any structural damage to the brain.[4] Since then, at least twenty more MRI-based structural neuroimaging studies have studied the effect of ECT on the brain. The earliest MRI studies in the early 1990s focused on detecting structural damage following ECT. All of these studies were prospective in design, with the first MRI scan done at baseline and a second MRI scan performed post ECT.[9],[11],[12],[13],[41] While most of the studies imaged the patient once around 24 h after receiving ECT, some studies performed multiple post ECT neuroimaging in the first 24 h after ECT to better capture the acute changes. A single study by Coffey et al. Followed up the patients for a duration of 6 months and repeated neuroimaging again at 6 months in order to capture any long-term changes following ECT.[10]The most important conclusion which emerged from this early series of studies was that there was no evidence of cortical atrophy, change in ventricle size, or increase in white matter hyperintensities.[4] The next major conclusion was that there appeared to be an increase in the T1 and T2 relaxation time immediately following ECT, which returned to normal within 24 h.

This supported the theory that immediately following ECT, there appears to be a temporary breakdown of the blood–brain barrier, leading to water influx into the brain tissue.[11] The last significant observation by Coffey et al. In 1991 was that there was no significant temporal changes in the total volumes of the frontal lobes, temporal lobes, or amygdala–hippocampal complex.[10] This was, however, something which would later be refuted by high-resolution MRI studies. Nonetheless, one inescapable conclusion of these early studies was that there was no evidence of any gross structural brain changes following administration of ECT. Much later in 2007, Szabo et al. Used diffusion-weighted MRI to image patients in the immediate post ECT period and failed to observe any obvious brain tissue changes following ECT.[17]The next major breakthrough came in 2010 when Nordanskog et al.

Demonstrated that there was a significant increase in the volume of the hippocampus bilaterally following a course of ECT in a cohort of patients with depressive illness.[18] This contradicted the earlier observations by Coffey et al. That there was no volume increase in any part of the brain following ECT.[10] This was quite an exciting finding and was followed by several similar studies. However, the perspective of these studies was quite different from the early studies. In contrast to the early studies looking for the evidence of ECT-related brain damage, the newer studies were focused more on elucidating the mechanism of action of ECT. Further on in 2014, Nordanskog et al.

In a follow-up study showed that though there was a significant increase in the volume of the hippocampus 1 week after a course of ECT, the hippocampal volume returned to the baseline after 6 months.[19] Two other studies in 2013 showed that in addition to the hippocampus, the amygdala also showed significant volume increase following ECT.[20],[21] A series of structural neuroimaging studies after that have expanded on these findings and as of now, gray matter volume increase following ECT has been demonstrated in the hippocampus, amygdala, anterior temporal pole, subgenual cortex,[21] right caudate nucleus, and the whole of the medial temporal lobe (MTL) consisting of the hippocampus, amygdala, insula, and the posterosuperior temporal cortex,[24] para hippocampi, right subgenual anterior cingulate gyrus, and right anterior cingulate gyrus,[25] left cerebellar area VIIa crus I,[29] putamen, caudate nucleus, and nucleus acumbens [31] and clusters of increased cortical thickness involving the temporal pole, middle and superior temporal cortex, insula, and inferior temporal cortex.[27] However, the most consistently reported and replicated finding has been the bilateral increase in the volume of the hippocampus and amygdala. In light of these findings, it has been tentatively suggested that ECT acts by inducing neuronal regeneration in the hippocampus – amygdala complex.[42],[43] However, there are certain inconsistencies to this hypothesis. Till date, only one study – Nordanskog et al., 2014 – has followed study patients for a long term – 6 months in their case. And significantly, the authors found out that after increasing immediately following ECT, the hippocampal volume returns back to baseline by 6 months.[19] This, however, was not associated with the relapse of depressive symptoms. Another area of significant confusion has been the correlation of hippocampal volume increase with improvement of depressive symptoms.

Though almost all studies demonstrate a significant increase in hippocampal volume following ECT, a majority of studies failed to demonstrate a correlation between symptom improvement and hippocampal volume increase.[19],[20],[22],[24],[28] However, a significant minority of volumetric studies have demonstrated correlation between increase in hippocampal and/or amygdala volume and improvement of symptoms.[21],[25],[30]Another set of studies have used diffusion tensor imaging, functional MRI (fMRI), anatomical connectome, and structural network analysis to study the effect of ECT on the brain. The first of these studies by Abbott et al. In 2014 demonstrated that on fMRI, the connectivity between right and left hippocampus was significantly reduced in patients with severe depression. It was also shown that the connectivity was normalized following ECT, and symptom improvement was correlated with an increase in connectivity.[22] In a first of its kind DTI study, Lyden et al. In 2014 demonstrated that fractional anisotropy which is a measure of white matter tract or fiber density is increased post ECT in patients with severe depression in the anterior cingulum, forceps minor, and the dorsal aspect of the left superior longitudinal fasciculus.

The authors suggested that ECT acts to normalize major depressive disorder-related abnormalities in the structural connectivity of the dorsal fronto-limbic pathways.[23] Another DTI study in 2015 constructed large-scale anatomical networks of the human brain – connectomes, based on white matter fiber tractography. The authors found significant reorganization in the anatomical connections involving the limbic structure, temporal lobe, and frontal lobe. It was also found that connection changes between amygdala and para hippocampus correlated with reduction in depressive symptoms.[26] In 2016, Wolf et al. Used a source-based morphometry approach to study the structural networks in patients with depression and schizophrenia and the effect of ECT on the same. It was found that the medial prefrontal cortex/anterior cingulate cortex (ACC/MPFC) network, MTL network, bilateral thalamus, and left cerebellar regions/precuneus exhibited significant difference between healthy controls and the patient population.

It was also demonstrated that administration of ECT leads to significant increase in the network strength of the ACC/MPFC network and the MTL network though the increase in network strength and symptom amelioration were not correlated.[32]Building on these studies, a recently published meta-analysis has attempted a quantitative synthesis of brain volume changes – focusing on hippocampal volume increase following ECT in patients with major depressive disorder and bipolar disorder. The authors initially selected 32 original articles from which six articles met the criteria for quantitative synthesis. The results showed significant increase in the volume of the right and left hippocampus following ECT. For the rest of the brain regions, the heterogeneity in protocols and imaging techniques did not permit a quantitative analysis, and the authors have resorted to a narrative review similar to the present one with similar conclusions.[44] Focusing exclusively on hippocampal volume change in ECT, Oltedal et al. In 2018 conducted a mega-analysis of 281 patients with major depressive disorder treated with ECT enrolled at ten different global sites of the Global ECT-MRI Research Collaboration.[45] Similar to previous studies, there was a significant increase in hippocampal volume bilaterally with a dose–response relationship with the number of ECTs administered.

Furthermore, bilateral (B/L) ECT was associated with an equal increase in volume in both right and left hippocampus, whereas right unilateral ECT was associated with greater volume increase in the right hippocampus. Finally, contrary to expectation, clinical improvement was found to be negatively correlated with hippocampal volume.Thus, a review of the current evidence amply demonstrates that from looking for ECT-related brain damage – and finding none, we have now moved ahead to looking for a mechanistic understanding of the effect of ECT. In this regard, it has been found that ECT does induce structural changes in the brain – a fact which has been seized upon by some to claim that ECT causes brain damage.[46] Such statements should, however, be weighed against the definition of damage as understood by the scientific medical community and patient population. Neuroanatomical changes associated with effective ECT can be better described as ECT-induced brain neuroplasticity or ECT-induced brain neuromodulation rather than ECT-induced brain damage. Metabolic Neuroimaging Studies.

Magnetic Resonance Spectroscopic Imaging Magnetic resonance spectroscopic imaging (MRSI) uses a phase-encoding procedure to map the spatial distribution of magnetic resonance (MR) signals of different molecules. The crucial difference, however, is that while MRI maps the MR signals of water molecules, MRSI maps the MR signals generated by different metabolites – such as N-acetyl aspartate (NAA) and choline-containing compounds. However, the concentration of these metabolites is at least 10,000 times lower than water molecules and hence the signal strength generated would also be correspondingly lower. However, MRSI offers us the unique advantage of studying in vivo the change in the concentration of brain metabolites, which has been of great significance in fields such as psychiatry, neurology, and basic neuroscience research.[47]MRSI studies on ECT in patients with depression have focused largely on four metabolites in the human brain – NAA, choline-containing compounds (Cho) which include majorly cell membrane compounds such as glycerophosphocholine, phosphocholine and a miniscule contribution from acetylcholine, creatinine (Cr) and glutamine and glutamate together (Glx). NAA is located exclusively in the neurons, and is suggested to be a marker of neuronal viability and functionality.[48] Choline-containing compounds (Cho) mainly include the membrane compounds, and an increase in Cho would be suggestive of increased membrane turnover.

Cr serves as a marker of cellular energy metabolism, and its levels are usually expected to remain stable. The regions which have been most widely studied in MRSI studies include the bilateral hippocampus and amygdala, dorsolateral prefrontal cortex (DLPFC), and ACC.Till date, five MRSI studies have measured NAA concentration in the hippocampus before and after ECT. Of these, three studies showed that there is no significant change in the NAA concentration in the hippocampus following ECT.[33],[38],[49] On the other hand, two recent studies have demonstrated a statistically significant reduction in NAA concentration in the hippocampus following ECT.[39],[40] The implications of these results are of significant interest to us in answering our titular question. A normal level of NAA following ECT could signify that there is no significant neuronal death or damage following ECT, while a reduction would signal the opposite. However, a direct comparison between these studies is complicated chiefly due to the different ECT protocols, which has been used in these studies.

It must, however, be acknowledged that the three older studies used 1.5 T MRI, whereas the two newer studies used a higher 3 T MRI which offers betters signal-to-noise ratio and hence lesser risk of errors in the measurement of metabolite concentrations. The authors of a study by Njau et al.[39] argue that a change in NAA levels might reflect reversible changes in neural metabolism rather than a permanent change in the number or density of neurons and also that reduced NAA might point to a change in the ratio of mature to immature neurons, which, in fact, might reflect enhanced adult neurogenesis. Thus, the authors warn that to conclude whether a reduction in NAA concentration is beneficial or harmful would take a simultaneous measurement of cognitive functioning, which was lacking in their study. In 2017, Cano et al. Also demonstrated a significant reduction in NAA/Cr ratio in the hippocampus post ECT.

More significantly, the authors also showed a significant increase in Glx levels in the hippocampus following ECT, which was also associated with an increase in hippocampal volume.[40] To explain these three findings, the authors proposed that ECT produces a neuroinflammatory response in the hippocampus – likely mediated by Glx, which has been known to cause inflammation at higher concentrations, thereby accounting for the increase in hippocampal volume with a reduction in NAA concentration. The cause for the volume increase remains unclear – with the authors speculating that it might be due to neuronal swelling or due to angiogenesis. However, the same study and multiple other past studies [21],[25],[30] have demonstrated that hippocampal volume increase was correlated with clinical improvement following ECT. Thus, we are led to the hypothesis that the same mechanism which drives clinical improvement with ECT is also responsible for the cognitive impairment following ECT. Whether this is a purely neuroinflammatory response or a neuroplastic response or a neuroinflammatory response leading to some form of neuroplasticity is a critical question, which remains to be answered.[40]Studies which have analyzed NAA concentration change in other brain areas have also produced conflicting results.

The ACC is another area which has been studied in some detail utilizing the MRSI technique. In 2003, Pfleiderer et al. Demonstrated that there was no significant change in the NAA and Cho levels in the ACC following ECT. This would seem to suggest that there was no neurogenesis or membrane turnover in the ACC post ECT.[36] However, this finding was contested by Merkl et al. In 2011, who demonstrated that NAA levels were significantly reduced in the left ACC in patients with depression and that these levels were significantly elevated following ECT.[37] This again is contested by Njau et al.

Who showed that NAA levels are significantly reduced following ECT in the left dorsal ACC.[39] A direct comparison of these three studies is complicated by the different ECT and imaging parameters used and hence, no firm conclusion can be made on this point at this stage. In addition to this, one study had demonstrated increased NAA levels in the amygdala following administration of ECT,[34] with a trend level increase in Cho levels, which again is suggestive of neurogenesis and/or neuroplasticity. A review of studies on the DLPFC reveals a similarly confusing picture with one study, each showing no change, reduction, and elevation of concentration of NAA following ECT.[35],[37],[39] Here, again, a direct comparison of the three studies is made difficult by the heterogeneous imaging and ECT protocols followed by them.A total of five studies have analyzed the concentration of choline-containing compounds (Cho) in patients undergoing ECT. Conceptually, an increase in Cho signals is indicative of increased membrane turnover, which is postulated to be associated with synaptogenesis, neurogenesis, and maturation of neurons.[31] Of these, two studies measured Cho concentration in the B/L hippocampus, with contrasting results. Ende et al.

In 2000 demonstrated a significant elevation in Cho levels in B/L hippocampus after ECT, while Jorgensen et al. In 2015 failed to replicate the same finding.[33],[38] Cho levels have also been studied in the amygdala, ACC, and the DLPFC. However, none of these studies showed a significant increase or decrease in Cho levels before and after ECT in the respective brain regions studied. In addition, no significant difference was seen in the pre-ECT Cho levels of patients compared to healthy controls.[34],[36],[37]In review, we must admit that MRSI studies are still at a preliminary stage with significant heterogeneity in ECT protocols, patient population, and regions of the brain studied. At this stage, it is difficult to draw any firm conclusions except to acknowledge the fact that the more recent studies – Njau et al., 2017, Cano, 2017, and Jorgensen et al., 2015 – have shown decrease in NAA concentration and no increase in Cho levels [38],[39],[40] – as opposed to the earlier studies by Ende et al.[33] The view offered by the more recent studies is one of a neuroinflammatory models of action of ECT, probably driving neuroplasticity in the hippocampus.

This would offer a mechanistic understanding of both clinical response and the phenomenon of cognitive impairment associated with ECT. However, this conclusion is based on conjecture, and more work needs to be done in this area. Body Fluid Biochemical Marker Studies Another line of evidence for analyzing the effect of ECT on the human brain is the study of concentration of neurotrophins in the plasma or serum. Neurotrophins are small protein molecules which mediate neuronal survival and development. The most prominent among these is brain-derived neurotrophic factor (BDNF) which plays an important role in neuronal survival, plasticity, and migration.[50] A neurotrophic theory of mood disorders was suggested which hypothesized that depressive disorders are associated with a decreased expression of BDNF in the limbic structures, resulting in the atrophy of these structures.[51] It was also postulated that antidepressant treatment has a neurotrophic effect which reverses the neuronal cell loss, thereby producing a therapeutic effect.

It has been well established that BDNF is decreased in mood disorders.[52] It has also been shown that clinical improvement of depression is associated with increase in BDNF levels.[53] Thus, serum BDNF levels have been tentatively proposed as a biomarker for treatment response in depression. Recent meta-analytic evidence has shown that ECT is associated with significant increase in serum BDNF levels in patients with major depressive disorder.[54] Considering that BDNF is a potent stimulator of neurogenesis, the elevation of serum BDNF levels following ECT lends further credence to the theory that ECT leads to neurogenesis in the hippocampus and other limbic structures, which, in turn, mediates the therapeutic action of ECT. Cognitive Impairment Studies Cognitive impairment has always been the single-most important side effect associated with ECT.[55] Concerns regarding long-term cognitive impairment surfaced soon after the introduction of ECT and since then has grown to become one of the most controversial aspects of ECT.[56] Anti-ECT groups have frequently pointed out to cognitive impairment following ECT as evidence of ECT causing brain damage.[56] A meta-analysis by Semkovska and McLoughlin in 2010 is one of the most detailed studies which had attempted to settle this long-standing debate.[57] The authors reviewed 84 studies (2981 participants), which had used a combined total of 22 standardized neuropsychological tests assessing various cognitive functions before and after ECT in patients diagnosed with major depressive disorder. The different cognitive domains reviewed included processing speed, attention/working memory, verbal episodic memory, visual episodic memory, spatial problem-solving, executive functioning, and intellectual ability. The authors concluded that administration of ECT for depression is associated with significant cognitive impairment in the first few days after ECT administration.

However, it was also seen that impairment in cognitive functioning resolved within a span of 2 weeks and thereafter, a majority of cognitive domains even showed mild improvement compared to the baseline performance. It was also demonstrated that not a single cognitive domain showed persistence of impairment beyond 15 days after ECT.Memory impairment following ECT can be analyzed broadly under two conceptual schemes – one that classifies memory impairment as objective memory impairment and subjective memory impairment and the other that classifies it as impairment in anterograde memory versus impairment in retrograde memory. Objective memory can be roughly defined as the ability to retrieve stored information and can be measured by various standardized neuropsychological tests. Subjective memory or meta-memory, on the other hand, refers to the ability to make judgments about one's ability to retrieve stored information.[58] As described previously, it has been conclusively demonstrated that anterograde memory impairment does not persist beyond 2 weeks after ECT.[57] However, one of the major limitations of this meta-analysis was the lack of evidence on retrograde amnesia following ECT. This is particularly unfortunate considering that it is memory impairment – particularly retrograde amnesia which has received the most attention.[59] In addition, reports of catastrophic retrograde amnesia have been repeatedly held up as sensational evidence of the lasting brain damage produced by ECT.[59] Admittedly, studies on retrograde amnesia are fewer and less conclusive than on anterograde amnesia.[60],[61] At present, the results are conflicting, with some studies finding some impairment in retrograde memory – particularly autobiographical retrograde memory up to 6 months after ECT.[62],[63],[64],[65] However, more recent studies have failed to support this finding.[66],[67] While they do demonstrate an impairment in retrograde memory immediately after ECT, it was seen that this deficit returned to pre-ECT levels within a span of 1–2 months and improved beyond baseline performance at 6 months post ECT.[66] Adding to the confusion are numerous factors which confound the assessment of retrograde amnesia.

It has been shown that depressive symptoms can produce significant impairment of retrograde memory.[68],[69] It has also been demonstrated that sine-wave ECT produces significantly more impairment of retrograde memory as compared to brief-pulse ECT.[70] However, from the 1990s onward, sine-wave ECT has been completely replaced by brief-pulse ECT, and it is unclear as to the implications of cognitive impairment from the sine-wave era in contemporary ECT practice.Another area of concern are reports of subjective memory impairment following ECT. One of the pioneers of research into subjective memory impairment were Squire and Chace who published a series of studies in the 1970s demonstrating the adverse effect of bilateral ECT on subjective assessment of memory.[62],[63],[64],[65] However, most of the studies conducted post 1980 – from when sine-wave ECT was replaced by brief-pulse ECT report a general improvement in subjective memory assessments following ECT.[71] In addition, most of the recent studies have failed to find a significant association between measures of subjective and objective memory.[63],[66],[70],[72],[73],[74] It has also been shown that subjective memory impairment is strongly associated with the severity of depressive symptoms.[75] In light of these facts, the validity and value of measures of subjective memory impairment as a marker of cognitive impairment and brain damage following ECT have been questioned. However, concerns regarding subjective memory impairment and catastrophic retrograde amnesia continue to persist, with significant dissonance between the findings of different research groups and patient self-reports in various media.[57]Some studies reported the possibility of ECT being associated with the development of subsequent dementia.[76],[77] However, a recent large, well-controlled prospective Danish study found that the use of ECT was not associated with elevated incidence of dementia.[78] Conclusion Our titular question is whether ECT leads to brain damage, where damage indicates destruction or degeneration of nerves or nerve tracts in the brain, which leads to loss of function. This issue was last addressed by Devanand et al. In 1994 since which time our understanding of ECT has grown substantially, helped particularly by the advent of modern-day neuroimaging techniques which we have reviewed in detail.

And, what these studies reveal is rather than damaging the brain, ECT has a neuromodulatory effect on the brain. The various lines of evidence – structural neuroimaging studies, functional neuroimaging studies, neurochemical and metabolic studies, and serum BDNF studies all point toward this. These neuromodulatory changes have been localized to the hippocampus, amygdala, and certain other parts of the limbic system. How exactly these changes mediate the improvement of depressive symptoms is a question that remains unanswered. However, there is little by way of evidence from neuroimaging studies which indicates that ECT causes destruction or degeneration of neurons.

Though cognitive impairment studies do show that there is objective impairment of certain functions – particularly memory immediately after ECT, these impairments are transient with full recovery within a span of 2 weeks. Perhaps, the single-most important unaddressed concern is retrograde amnesia, which has been shown to persist for up to 2 months post ECT. In this regard, the recent neurometabolic studies have offered a tentative mechanism of action of ECT, producing a transient inflammation in the limbic cortex, which, in turn, drives neurogenesis, thereby exerting a neuromodulatory effect. This hypothesis would explain both the cognitive adverse effects of ECT – due to the transient inflammation – and the long-term improvement in mood – neurogenesis in the hippocampus. Although unproven at present, such a hypothesis would imply that cognitive impairment is tied in with the mechanism of action of ECT and not an indicator of damage to the brain produced by ECT.The review of literature suggests that ECT does cause at least structural and functional changes in the brain, and these are in all probability related to the effects of the ECT.

However, these cannot be construed as brain damage as is usually understood. Due to the relative scarcity of data that directly examines the question of whether ECT causes brain damage, it is not possible to conclusively answer this question. However, in light of enduring ECT survivor accounts, there is a need to design studies that specifically answer this question.Financial support and sponsorshipNil.Conflicts of interestThere are no conflicts of interest.

There is a famous example of the fear, pain and joy concept told by Howard Schubiner, M.D., a list of foods to avoid on antabuse leading pain view researcher, of a construction worker who stepped on a nail that went through the sole of his boot and came out the top of the boot. Upon seeing the nail emerge through the top of his boot, the man began to scream in pain. He was taken to the list of foods to avoid on antabuse emergency room, where he was given strong pain medication before they were able to get the boot off his foot.

When they got the boot off his foot they discovered that the nail had gone between his toes and left no mark on his foot at all. So why did list of foods to avoid on antabuse he experience pain?. Because his brain was expecting it based on what he saw.

That is the power of the list of foods to avoid on antabuse brain – to create the sensation to protect the body from perceived danger. This is anexample of the power of the brain to create pain based on fear and expectation.It neuro-circuits in the brain causing the pain responding to danger signals. Becausethe sensation of pain is one of the brain’s responses to danger signals, anyexperience that increases the potential of danger signals can increase thepossibility of pain signals.

Fear is one ofthose things that list of foods to avoid on antabuse can increase the danger signal. For example, if a person hashad an injury in their foot that resulted in pain while weight bearing, thenthey may, very understandably, fear bearing weight in the future. That fearwill then turn on the danger signal in the brain and increase the likelihood ofpain being list of foods to avoid on antabuse experienced.

It can become a vicious cycle. This list of foods to avoid on antabuse type of painis real pain, because all pain is real pain. Anyone who says “it’s all in yourhead” is being insensitive and judgmental.

The truth is, all pain starts in ourhead, as a response to the danger alarm that says something is wrong. Thisdanger alarm might be triggered from a structural injury to the body, list of foods to avoid on antabuse or thefear of expecting pain, or the fear of social rejection, or the emotional painof a traumatic memory, or anything that the alarm system perceives as adanger. This type of response is an unconscious response in the brain, not a choice that people make.

One way to check to see list of foods to avoid on antabuse if pain is related to the neuro-circuits is to use the imagination. If someone imagines doing the thing that has caused pain in the past and experiences pain or fear while imagining the movement or the situation, it is a good sign that it is learned neuro-circuits in the brain causing the pain. This is good list of foods to avoid on antabuse news because the brain can be rewired.

Once people know that their brain may be creating the sensation of pain, it can free them to change it. There are anumber of ways a person can rewire the brain. One good way list of foods to avoid on antabuse is to reduce thefear related to anticipating pain.

Self-talk and affirmations can be used toreduce fear. Once a person knows that all or list of foods to avoid on antabuse some of their pain isneuro-circuit pain, and that it is not structural damage, they can say tothemselves “I am strong and healthy. There is nothing wrong with this part ofmy body.

I am list of foods to avoid on antabuse okay. I am safe. There is no danger.” This can help turn off thedanger signal.

In comparison, when list of foods to avoid on antabuse a person says, “There is something wrongwith me. I am damaged,” the alarm system is turned on, which will perpetuatethe pain. It may sound simple,but list of foods to avoid on antabuse for many people this is the beginning of changing the brain, rewiringneuro-circuits to stop the fear of pain, stop the tripping of the danger alarm,and break the cycle.

But just like learning any new skill, which all involvedmaking neuro-circuit connections, it can take time and rehearsal. This rewiring canbecome even more powerful when combined with other tools to rewire the brain.Another tool is the use of deep breaths, which lets the danger alarm know thatthings are list of foods to avoid on antabuse okay. Another tool is the use of laughter and humor.

Participatingin mindfulness, playfulness and joy can also rewire the brain to turn off thefear signals. Participating in any of these activities, or even imagining thesethings, during the previously feared movement or situation can help list of foods to avoid on antabuse rewire thebrain. For more information on this, Dr.

Schubiner has created a series of easy-to-understand animated list of foods to avoid on antabuse video beginning with “What is pain.” For those who need more intense treatment for mental health conditions, MidMichigan Health provides an intensive outpatient program called Psychiatric Partial Hospitalization Program at MidMichigan Medical Center – Gratiot. Those interested in more information about the PHP program may call (989) 466-3253. Those interested in more information on MidMichigan’s list of foods to avoid on antabuse comprehensive behavioral health programs may visit www.midmichigan.org/mentalhealth.Each year, more than a million families in the United States experience a miscarriage, stillbirth or death of an infant.

Yet because these events can be emotionally difficult to discuss, there is little public awareness, so families may not always get the support they need. October is Pregnancy and Infant Loss Awareness Month, a time to list of foods to avoid on antabuse show support for these families, highlight available resources and build understanding of how family, friends and the community can help. If you visit a MidMichiganHealth facility during the month of October, you may notice staff wearing pinkand blue ribbons to show their support.

We will also participate in theInternational Wave of Light, a worldwide remembrance event on October 15, 7 to 8p.m. During this time, candles will be lit at the entrances of MidMichigan’sMedical Centers in Alma, list of foods to avoid on antabuse Alpena, Midland and West Branch (the sites of our fourMaternity Centers) to honor babies gone too soon and their families. Patients,staff and community members are welcome to attend.

Resources for Grieving Parents Your primarycare doctor or OB/Gyn can be a good first contact to help you understand thephysical and emotional impact of list of foods to avoid on antabuse a loss and to identify other resources. MidMichigan Home Care offers grief support for individuals and families who have lost a loved one, including education, support groups, short-term counseling and referrals to community professionals for longer-term follow-up. For more information, list of foods to avoid on antabuse visit www.midmichigan.org/grief or call (800) 862-5002.

There are manylocal and national nonprofits that specialize in helping families throughinfant and pregnancy loss. Their services range from resources and materialsthat discuss what families can expect during the grieving process, to in-personand online support groups to financial assistance with funeral and otherexpenses. Some organizations focus on certain bereaved list of foods to avoid on antabuse family members, such asparents or siblings, or on specific causes of perinatal death.

Consider callingUnited Way’s 2-1-1 hotline to identify local agencies in your area that mayprovide targeted grief services. What to Say When Someone Loses a Child People tend list of foods to avoid on antabuse totreat pregnancy or infant loss as a taboo subject, so loved ones are oftenuncomfortable or unfamiliar with what to say or do. Some well-meaning peoplemay even say things that are more hurtful than helpful.

Experts recommend keepingyour condolences simple, following the family’s list of foods to avoid on antabuse cues, and asking about theirpreferences if you are unsure. Tips. Acknowledgetheir loss in short, simple phrases, such as, “I’m sorry for your loss.” Or “Iimagine this must be painful for you.” Offer to listen if they want to talk.It’s also okay to simply admit that you don’t know what to say.Askwhether it is okay to talk about the baby and to use the baby’s name.Peopleoften treat miscarriage as “no big deal,” but the value of a life is notproportional to the time spent on earth.

Gastricclinical geneticsgenetic screening/counsellingmolecular geneticsIntroductionGLI-Kruppel family member 3 (GLI3) encodes for a zinc finger transcription factor which plays a key role in the sonic hedgehog (SHH) signalling pathway essential in both limb and craniofacial development.1 2 In hand development, SHH is expressed in the zone of polarising activity (ZPA) on the posterior side of the handplate. The ZPA expresses SHH, creating a gradient of SHH from the posterior to the anterior side of the handplate. In the presence of SHH, full length GLI3-protein is produced (GLI3A), whereas absence of SHH causes cleavage of GLI3 into its repressor form (GLI3R).3 4 Abnormal expression of this SHH/GLI3R gradient can cause both preaxial and postaxial polydactyly.2Concordantly, pathogenic DNA variants in the GLI3 gene are known to cause multiple syndromes with craniofacial and limb involvement, such as. Acrocallosal syndrome5 (OMIM. 200990), Greig cephalopolysyndactyly syndrome6 (OMIM.

175700) and Pallister-Hall syndrome7 (OMIM. 146510). Also, in non-syndromic polydactyly, such as preaxial polydactyly-type 4 (PPD4, OMIM. 174700),8 pathogenic variants in GLI3 have been described. Out of these diseases, Pallister-Hall syndrome is the most distinct entity, defined by the presence of central polydactyly and hypothalamic hamartoma.9 The other GLI3 syndromes are defined by the presence of preaxial and/or postaxial polydactyly of the hand and feet with or without syndactyly (Greig syndrome, PPD4).

Also, various mild craniofacial features such as hypertelorism and macrocephaly can occur. Pallister-Hall syndrome is caused by truncating variants in the middle third of the GLI3 gene.10–12 The truncation of GLI3 causes an overexpression of GLI3R, which is believed to be the key difference between Pallister-Hall and the GLI3-mediated polydactyly syndromes.9 11 Although multiple attempts have been made, the clinical and genetic distinction between the GLI3-mediated polydactyly syndromes is less evident. This has for example led to the introduction of subGreig and the formulation of an Oro-facial-digital overlap syndrome.10 Other authors, suggested that we should not regard these diseases as separate entities, but as a spectrum of GLI3-mediated polydactyly syndromes.13Although phenotype/genotype correlation of the different syndromes has been cumbersome, clinical and animal studies do provide evidence that distinct regions within the gene, could be related to the individual anomalies contributing to these syndromes. First, case studies show isolated preaxial polydactyly is caused by both truncating and non-truncating variants throughout the GLI3 gene, whereas in isolated postaxial polydactyly cases truncating variants at the C-terminal side of the gene are observed.12 14 These results suggest two different groups of variants for preaxial and postaxial polydactyly. Second, recent animal studies suggest that posterior malformations in GLI3-mediated polydactyly syndromes are likely related to a dosage effect of GLI3R rather than due to the influence of an altered GLI3A expression.15Past attempts for phenotype/genotype correlation in GLI3-mediated polydactyly syndromes have directly related the diagnosed syndrome to the observed genotype.10–12 16 Focusing on individual hand phenotypes, such as preaxial and postaxial polydactyly and syndactyly might be more reliable because it prevents misclassification due to inconsistent use of syndrome definition.

Subsequently, latent class analysis (LCA) provides the possibility to relate a group of observed variables to a set of latent, or unmeasured, parameters and thereby identifying different subgroups in the obtained dataset.17 As a result, LCA allows us to group different phenotypes within the GLI3-mediated polydactyly syndromes and relate the most important predictors of the grouped phenotypes to the observed GLI3 variants.The aim of our study was to further investigate the correlation of the individual phenotypes to the genotypes observed in GLI3-mediated polydactyly syndromes, using LCA. Cases were obtained by both literature review and the inclusion of local clinical cases. Subsequently, we identified two subclasses of limb anomalies that relate to the underlying GLI3 variant. We provide evidence for two different phenotypic and genotypic groups with predominantly preaxial and postaxial hand and feet anomalies, and we specify those cases with a higher risk for corpus callosum anomalies.MethodsLiterature reviewThe Human Gene Mutation Database (HGMD Professional 2019) was reviewed to identify known pathogenic variants in GLI3 and corresponding phenotypes.18 All references were obtained and cases were included when they were diagnosed with either Greig or subGreig syndrome or PPD4.10–12 Pallister-Hall syndrome and acrocallosal syndrome were excluded because both are regarded distinct syndromes and rather defined by the presence of the non-hand anomalies, than the presence of preaxial or postaxial polydactyly.13 19 Isolated preaxial or postaxial polydactyly were excluded for two reasons. The phenotype/genotype correlations are better understood and both anomalies can occur sporadically which could introduce falsely assumed pathogenic GLI3 variants in the analysis.

Additionally, cases were excluded when case-specific phenotypic or genotypic information was not reported or if these two could not be related to each other. Families with a combined phenotypic description, not reducible to individual family members, were included as one case in the analysis.Clinical casesThe Sophia Children’s Hospital Database was reviewed for cases with a GLI3 variant. Within this population, the same inclusion criteria for the phenotype were valid. Relatives of the index patients were also contacted for participation in this study, when they showed comparable hand, foot, or craniofacial malformations or when a GLI3 variant was identified. Phenotypes of the hand, foot and craniofacial anomalies of the patients treated in the Sophia Children's Hospital were collected using patient documentation.

Family members were identified and if possible, clinically verified. Alternatively, family members were contacted to verify their phenotypes. If no verification was possible, cases were excluded.PhenotypesThe phenotypes of both literature cases and local cases were extracted in a similar fashion. The most frequently reported limb and craniofacial phenotypes were dichotomised. The dichotomised hand and foot phenotypes were preaxial polydactyly, postaxial polydactyly and syndactyly.

Broad halluces or thumbs were commonly reported by authors and were dichotomised as a presentation of preaxial polydactyly. The extracted dichotomised craniofacial phenotypes were hypertelorism, macrocephaly and corpus callosum agenesis. All other phenotypes were registered, but not dichotomised.Pathogenic GLI3 variantsAll GLI3 variants were extracted and checked using Alamut Visual V.2.14. If indicated, variants were renamed according to standard Human Genome Variation Society nomenclature.20 Variants were grouped in either missense, frameshift, nonsense or splice site variants. In the group of frameshift variants, a subgroup with possible splice site effect were identified for subgroup analysis when indicated.

Similarly, nonsense variants prone for nonsense mediated decay (NMD) and nonsense variants with experimentally confirmed NMD were identified.21 Deletions of multiple exons, CNVs and translocations were excluded for analysis. A full list of included mutations is available in the online supplementary materials.Supplemental materialThe location of the variant was compared with five known structural domains of the GLI3 gene. (1) repressor domain, (2) zinc finger domain, (3) cleavage site, (4) activator domain, which we defined as a concatenation of the separately identified transactivation zones, the CBP binding domain and the mediator binding domain (MBD) and (5) the MID1 interaction region domain.1 6 22–24 The boundaries of each of the domains were based on available literature (figure 1, exact locations available in the online supplementary materials). The boundaries used by different authors did vary, therefore a consensus was made.In this figure the posterior probability of an anterior phenotype is plotted against the location of the variant, stratified for the type of mutation that was observed. For better overview, only variants with a location effect were displayed.

The full figure, including all variant types, can be found in the online supplementary figure 1. Each mutation is depicted as a dot, the size of the dot represents the number of observations for that variant. If multiple observations were made, the mean posterior odds and IQR are plotted. For the nonsense variants, variants that were predicted to produce nonsense mediated decay, are depicted using a triangle. Again, the size indicates the number of observations." data-icon-position data-hide-link-title="0">Figure 1 In this figure the posterior probability of an anterior phenotype is plotted against the location of the variant, stratified for the type of mutation that was observed.

Polytomous variable LCA, poLCA V.1.4.1.). We used our LCA to detect the number of phenotypic subgroups in the dataset and subsequently predict a class membership for each case in the dataset based on the posterior probabilities.In order to make a reliable prediction, only phenotypes that were sufficiently reported and/or ruled out were feasible for LCA, limiting the analysis to preaxial polydactyly, postaxial polydactyly and syndactyly of the hands and feet. Only full cases were included. To determine the optimal number of classes, we fitted a series of models ranging from a one-class to a six-class model.

The optimal number of classes was based on the conditional Akaike information criterion (cAIC), the non adjusted and the sample-size adjusted Bayesian information criterion (BIC and aBIC) and the obtained entropy.25 The explorative LCA produces both posterior probabilities per case for both classes and predicted class membership. Using the predicted class membership, the phenotypic features per class were determined in a univariate analysis (χ2, SPSS V.25). Using the posterior probabilities on latent class (LC) membership, a scatter plot was created using the location of the variant on the x-axis and the probability of class membership on the y-axis for each of the types of variants (Tibco Spotfire V.7.14). Using these scatter plots, variants that give similar phenotypes were clustered.Genotype/phenotype correlationBecause an LC has no clinical value, the correlation between genotypes and phenotypes was investigated using the predictor phenotypes and the clustered phenotypes. First, those phenotypes that contribute most to LC membership were identified.

Second those phenotypes were directly related to the different types of variants (missense, nonsense, frameshift, splice site) and their clustered locations. Quantification of the relation was performed using a univariate analysis using a χ2 test. Because of our selection criteria, meaning patients at least have two phenotypes, a multivariate using a logistic regression analysis was used to detect the most significant predictors in the overall phenotype (SPSS V.25). Finally, we explored the relation of the clustered genotypes to the presence of corpus callosum agenesis, a rare malformation in GLI3-mediated polydactyly syndromes which cannot be readily diagnosed without additional imaging.ResultsWe included 251 patients from the literature and 46 local patients,10–12 16 21 26–43 in total 297 patients from 155 different families with 127 different GLI3 variants, 32 of which were large deletions, CNVs or translocations. In six local cases, the exact variant could not be retrieved by status research.The distribution of the most frequently observed phenotypes and variants are presented in table 1.

Other recurring phenotypes included developmental delay (n=22), broad nasal root (n=23), frontal bossing or prominent forehead (n=16) and craniosynostosis (n=13), camptodactyly (n=8) and a broad first interdigital webspace of the foot (n=6).View this table:Table 1 Baseline phenotypes and genotypes of selected populationThe LCA model was fitted using the six defined hand/foot phenotypes. Model fit indices for the LCA are displayed in table 2. Based on the BIC, a two-class model has the best fit for our data. The four-class model does show a gain in entropy, however with a higher BIC and loss of df. Therefore, based on the majority of performance statistics and the interpretability of the model, a two-class model was chosen.

Table 3 displays the distribution of phenotypes and genotypes over the two classes.View this table:Table 2 Model fit indices for the one-class through six-class model evaluated in our LCAView this table:Table 3 Distribution of phenotypes and genotypes in the two latent classes (LC)Table 1 depicts the baseline phenotypes and genotypes in the obtained population. Note incomplete data especially in the cranium phenotypes. In total 259 valid genotypes were present. In total, 289 cases had complete data for all hand and foot phenotypes (preaxial polydactyly, postaxial polydactyly and syndactyly) and thus were available for LCA. Combined, for phenotype/genotype correlation 258 cases were available with complete genotypes and complete hand and foot phenotypes.Table 2 depicts the model fit indices for all models that have been fitted to our data.Table 3 depicts the distribution of phenotypes and genotypes over the two assigned LCs.

Hand and foot phenotypes were used as input for the LCA, thus are all complete cases. Malformation of the cranium and genotypes do have missing cases. Note that for the LCA, full case description was required, resulting in eight cases due to incomplete phenotypes. Out of these eight, one also had a genotype that thus needed to be excluded. Missingness of genotypic data was higher in LC2, mostly due to CNVs (table 1).In 54/60 cases, a missense variant produced a posterior phenotype.

Likewise, splice site variants show the same phenotype in 23/24 cases (table 3). For both frameshift and nonsense variants, this relation is not significant (52 anterior vs 54 posterior and 26 anterior vs 42 posterior, respectively). Therefore, only for nonsense and frameshift variants the location of the variant was plotted against the probability for LC2 membership in figure 1. A full scatterplot of all variants is available in online supplementary figure 1.Figure 1 reveals a pattern for these nonsense and frameshift variants that reveals that variants at the C-terminal of the gene predict anterior phenotypes. When relating the domains of the GLI3 protein to the observed phenotype, we observe that the majority of patients with a nonsense or frameshift variant in the repressor domain, the zinc finger domain or the cleavage site had a high probability of an LC2/anterior phenotype.

This group contains all variants that are either experimentally determined to be subject to NMD (triangle marker in figure 1) or predicted to be subject to NMD (diamond marker in figure 1). Frameshift and nonsense variants in the activator domain result in high probability for an LC1/posterior phenotype. These variants will be further referred to as truncating variants in the activator domain.The univariate relation of the individual phenotypes to these two groups of variants are estimated and presented in table 4. In our multivariate analysis, postaxial polydactyly of the foot and hand are the strongest predictors (Beta. 2.548, p<0001 and Beta.

1.47, p=0.013, respectively) for patients to have a truncating variant in the activator domain. Moreover, the effect sizes of preaxial polydactyly of the hand and feet (Beta. ˆ’0.797, p=0123 and −1.772, p=0.001) reveals that especially postaxial polydactyly of the foot is the dominant predictor for the genetic substrate of the observed anomalies.View this table:Table 4 Univariate and multivariate analysis of the phenotype/genotype correlationTable 4 shows exploration of the individual phenotypes on the genotype, both univariate and multivariate. The multivariate analysis corrects for the presence of multiple phenotypes in the underlying population.Although the craniofacial anomalies could not be included in the LCA, the relation between the observed anomalies and the identified genetic substrates can be studied. The prevalence of hypertelorism was equally distributed over the two groups of variants (47/135 vs 21/47 respectively, p<0.229).

However for corpus callosum agenesis and macrocephaly, there was a higher prevalence in patients with a truncating variant in the activator domain (3/75 vs 11/41, p<0.001. OR. 8.8, p<0.001) and 42/123 vs 24/48, p<0.05). Noteworthy is the fact that 11/14 cases with corpus callosum agenesis in the dataset had a truncating variant in the activator domain.DiscussionIn this report, we present new insights into the correlation between the phenotype and the genotype in patients with GLI3-mediated polydactyly syndromes. We illustrate that there are two LCs of patients, best predicted by postaxial polydactyly of the hand and foot for LC1, and the preaxial polydactyly of the hand and foot and syndactyly of the foot for LC2.

Patients with postaxial phenotypes have a higher risk of having a truncating variant in the activator domain of the GLI3 gene which is also related to a higher risk of corpus callosum agenesis. These results suggest a functional difference between truncating variants on the N-terminal and the C-terminal side of the GLI3 cleavage site.Previous attempts of phenotype to genotype correlation have not yet provided the clinical confirmation of these assumed mechanisms in the pathophysiology of GLI3-mediated polydactyly syndromes. Johnston et al have successfully determined the Pallister-Hall region in which truncating variants produce a Pallister-Hall phenotype rather than Greig syndrome.11 However, in their latest population study, subtypes of both syndromes were included to explain the full spectrum of observed malformations. In 2015, Demurger et al reported the higher incidence of corpus callosum agenesis in the Greig syndrome population with truncating mutations in the activator domain.12 Al-Qattan in his review summarises the concept of a spectrum of anomalies dependent on haplo-insufficiency (through different mechanisms) and repressor overexpression.13 However, he bases this theory mainly on reviewed experimental data. Our report is the first to provide an extensive clinical review of cases that substantiate the phenotypic difference between the two groups that could fit the suggested mechanisms.

We agree with Al-Qattan et al that a variation of anomalies can be observed given any pathogenic variant in the GLI3 gene, but overall two dominant phenotypes are present. A population with predominantly preaxial anomalies and one with postaxial anomalies. The presence of preaxial or postaxial polydactyly and syndactyly is not mutually exclusive for one of these two subclasses. Meaning that preaxial polydactyly can co-occur with postaxial polydactyly. However, truncating mutations in the activator domain produce a postaxial phenotype, as can be derived from the risk in table 4.

The higher risk of corpus callosum agenesis in this population shows that differentiating between a preaxial phenotype and a postaxial phenotype, instead of between the different GLI3-mediated polydactyly syndromes, might be more relevant regarding diagnostics for corpus callosum agenesis.We chose to use LCA as an exploratory tool only in our population for two reasons. First of all, LCA can be useful to identify subgroups, but there is no ‘true’ model or number of subgroups you can detect. The best fitting model can only be estimated based on the available measures and approximates the true subgroups that might be present. Second, LC membership assignment is a statistical procedure based on the posterior probability, with concordant errors of the estimation, rather than a clinical value that can be measured or evaluated. Therefore, we decided to use our LCA only in an exploratory tool, and perform our statistics using the actual phenotypes that predict LC membership and the associated genotypes.

Overall, this method worked well to differentiate the two subgroups present in our dataset. However, outliers were observed. A qualitative analysis of these outliers is available in the online supplementary data.The genetic substrate for the two phenotypic clusters can be discussed based on multiple experiments. Overall, we hypothesise two genetic clusters. One that is due to haploinsufficiency and one that is due to abnormal truncation of the activator.

The hypothesised cluster of variants that produce haploinsufficiency is mainly based on the experimental data that confirms NMD in two variants and the NMD prediction of other nonsense variants in Alamut. For the frameshift variants, it is also likely that the cleavage of the zinc finger domain results in functional haploinsufficiency either because of a lack of signalling domains or similarly due to NMD. Missense variants could cause haploinsufficiency through the suggested mechanism by Krauss et al who have illustrated that missense variants in the MID1 domain hamper the functional interaction with the MID1-α4-PP2A complex, leading to a subcellular location of GLI3.24 The observed missense variants in our study exceed the region to which Krauss et al have limited the MID-1 interaction domain. An alternative theory is suggested by Zhou et al who have shown that missense variants in the MBD can cause deficiency in the signalling of GLI3A, functionally implicating a relative overexpression of GLI3R.22 However, GLI3R overexpression would likely produce a posterior phenotype, as determined by Hill et al in their fixed homo and hemizygous GLI3R models.15 Therefore, our hypothesis is that all included missense variants have a similar pathogenesis which is more likely in concordance with the mechanism introduced by Krauss et al. To our knowledge, no splice site variants have been functionally described in literature.

However, it is noted that the 15 and last exon encompasses the entire activator domain, thus any splice site mutation is by definition located on the 5′ side of the activator. Based on the phenotype, we would suggest that these variants fail to produce a functional protein. We hypothesise that the truncating variants of the activator domain lead to overexpression of GLI3R in SHH rich areas. In normal development, the presence of SHH prevents the processing of full length GLI34 into GLI3R, thus producing the full length activator. In patients with a truncating variant of the activator domain of GLI3, thus these variants likely have the largest effect in SHH rich areas, such as the ZPA located at the posterior side of the hand/footplate.

Moreover, the lack of posterior anomalies in the GLI3∆699/- mouse model (hemizygous fixed repressor model) compared with the GLI3∆699/∆699 mouse model (homozygous fixed repressor model), suggesting a dosage effect of GLI3R to be responsible for posterior hand anomalies.15 These findings are supported by Lewandowski et al, who show that the majority of the target genes in GLI signalling are regulated by GLI3R rather than GLI3A.44 Together, these findings suggest a role for the location and type of variant in GLI3-mediated syndromes.Interestingly, the difference between Pallister-Hall syndrome and GLI3-mediated polydactyly syndromes has also been attributed to the GLI3R overexpression. However, the difference in phenotype observed in the cases with a truncating variant in the activator domain and Pallister-Hall syndrome suggest different functional consequences. When studying figure 1, it is noted that the included truncating variants on the 3′ side of the cleavage site seldomly affect the CBP binding region, which could provide an explanation for the observed differences. This binding region is included in the Pallister-Hall region as defined by Johnston et al and is necessary for the downstream signalling with GLI1.10 11 23 45 Interestingly, recent reports show that pathogenic variants in GLI1 can produce phenotypes concordant with Ellis von Krefeld syndrome, which includes overlapping features with Pallister-Hall syndrome.46 The four truncating variants observed in this study that do affect the CBP but did not result in a Pallister-Hall phenotype are conflicting with this theory. Krauss et al postulate an alternative hypothesis, they state that the MID1-α4-PP2A complex, which is essential for GLI3A signalling, could also be the reason for overlapping features of Opitz syndrome, caused by variants in MID1, and Pallister-Hall syndrome.

Further analysis is required to fully appreciate the functional differences between truncating mutations that cause Pallister-Hall syndrome and those that result in GLI3-mediated polydactyly syndromes.For the clinical evaluation of patients with GLI3-mediated polydactyly syndromes, intracranial anomalies are likely the most important to predict based on the variant. Unfortunately, the presence of corpus callosum agenesis was not routinely investigated or reported thus this feature could not be used as an indicator phenotype for LC membership. Interestingly when using only hand and foot phenotypes, we did notice a higher prevalence of corpus callosum agenesis in patients with posterior phenotypes. The suggested relation between truncating mutations in the activator domain causing these posterior phenotypes and corpus callosum agenesis was statistically confirmed (OR. 8.8, p<0.001).

Functionally this relation could be caused by the GLI3-MED12 interaction at the MBD. Pathogenic DNA variants in MED12 can cause Opitz-Kaveggia syndrome, a syndrome in which presentation includes corpus callosum agenesis, broad halluces and thumbs.47In conclusion, there are two distinct phenotypes within the GLI3-mediated polydactyly population. Patients with more posteriorly and more anteriorly oriented hand anomalies. Furthermore, this difference is related to the observed variant in GLI3. We hypothesise that variants that cause haploinsufficiency produce anterior anomalies of the hand, whereas variants with abnormal truncation of the activator domain have more posterior anomalies.

Furthermore, patients that have a variant that produces abnormal truncation of the activator domain, have a greater risk for corpus callosum agenesis. Thus, we advocate to differentiate preaxial or postaxial oriented GLI3 phenotypes to explain the pathophysiology as well as to get a risk assessment for corpus callosum agenesis.Data availability statementData are available upon reasonable request.Ethics statementsPatient consent for publicationNot required.Ethics approvalThe research protocol was approved by the local ethics board of the Erasmus MC University Medical Center (MEC 2015-679)..

Acrocallosal syndrome5 (OMIM. 200990), Greig antabuse 250mg online cephalopolysyndactyly syndrome6 (OMIM.

175700) and Pallister-Hall syndrome7 (OMIM. 146510). Also, in non-syndromic polydactyly, such as preaxial polydactyly-type 4 (PPD4, OMIM. 174700),8 pathogenic variants in GLI3 have been described. Out of these diseases, Pallister-Hall syndrome is the most distinct entity, defined by the presence of central polydactyly and hypothalamic hamartoma.9 The other GLI3 syndromes are defined by the presence of preaxial and/or postaxial polydactyly of the hand and feet with or without syndactyly (Greig syndrome, PPD4).

Also, various mild craniofacial features such as hypertelorism and macrocephaly can occur. Pallister-Hall syndrome is caused by truncating variants in the middle third of the GLI3 gene.10–12 The truncation of GLI3 causes an overexpression of GLI3R, which is believed to be the key difference between Pallister-Hall and the GLI3-mediated polydactyly syndromes.9 11 Although multiple attempts have been made, the clinical and genetic distinction between the GLI3-mediated polydactyly syndromes is less evident. This has for example led to the introduction of subGreig and the formulation of an Oro-facial-digital overlap syndrome.10 Other authors, suggested that we should not regard these diseases as separate entities, but as a spectrum of GLI3-mediated polydactyly syndromes.13Although phenotype/genotype correlation of the different syndromes has been cumbersome, clinical and animal studies do provide evidence that distinct regions within the gene, could be related to the individual anomalies contributing to these syndromes. First, case studies show isolated preaxial polydactyly is caused by both truncating and non-truncating variants throughout the GLI3 gene, whereas in isolated postaxial polydactyly cases truncating variants at the C-terminal side of the gene are observed.12 14 These results suggest two different groups of variants for preaxial and postaxial polydactyly. Second, recent animal studies suggest that posterior malformations in GLI3-mediated polydactyly syndromes are likely related to a dosage effect of GLI3R rather than due to the influence of an altered GLI3A expression.15Past attempts for phenotype/genotype correlation in GLI3-mediated polydactyly syndromes have directly related the diagnosed syndrome to the observed genotype.10–12 16 Focusing on individual hand phenotypes, such as preaxial and postaxial polydactyly and syndactyly might be more reliable because it prevents misclassification due to inconsistent use of syndrome definition.

Subsequently, latent class analysis (LCA) provides the possibility to relate a group of observed variables to a set of latent, or unmeasured, parameters and thereby identifying different subgroups in the obtained dataset.17 As a result, LCA allows us to group different phenotypes within the GLI3-mediated polydactyly syndromes and relate the most important predictors of the grouped phenotypes to the observed GLI3 variants.The aim of our study was to further investigate the correlation of the individual phenotypes to the genotypes observed in GLI3-mediated polydactyly syndromes, using LCA. Cases were obtained by both literature review and the inclusion of local clinical cases. Subsequently, we identified two subclasses of limb anomalies that relate to the underlying GLI3 variant. We provide evidence for two different phenotypic and genotypic groups with predominantly preaxial and postaxial hand and feet anomalies, and we specify those cases with a higher risk for corpus callosum anomalies.MethodsLiterature reviewThe Human Gene Mutation Database (HGMD Professional 2019) was reviewed to identify known pathogenic variants in GLI3 and corresponding phenotypes.18 All references were obtained and cases were included when they were diagnosed with either Greig or subGreig syndrome or PPD4.10–12 Pallister-Hall syndrome and acrocallosal syndrome were excluded because both are regarded distinct syndromes and rather defined by the presence of the non-hand anomalies, than the presence of preaxial or postaxial polydactyly.13 19 Isolated preaxial or postaxial polydactyly were excluded for two reasons. The phenotype/genotype correlations are better understood and both anomalies can occur sporadically which could introduce falsely assumed pathogenic GLI3 variants in the analysis.

Additionally, cases were excluded when case-specific phenotypic or genotypic information was not reported or if these two could not be related to each other. Families with a combined phenotypic description, not reducible to individual family members, were included as one case in the analysis.Clinical casesThe Sophia Children’s Hospital Database was reviewed for cases with a GLI3 variant. Within this population, the same inclusion criteria for the phenotype were valid. Relatives of the index patients were also contacted for participation in this study, when they showed comparable hand, foot, or craniofacial malformations or when a GLI3 variant was identified. Phenotypes of the hand, foot and craniofacial anomalies of the patients treated in the Sophia Children's Hospital were collected using patient documentation.

Family members were identified and if possible, clinically verified. Alternatively, family members were contacted to verify their phenotypes. If no verification was possible, cases were excluded.PhenotypesThe phenotypes of both literature cases and local cases were extracted in a similar fashion. The most frequently reported limb and craniofacial phenotypes were dichotomised. The dichotomised hand and foot phenotypes were preaxial polydactyly, postaxial polydactyly and syndactyly.

Broad halluces or thumbs were commonly reported by authors and were dichotomised as a presentation of preaxial polydactyly. The extracted dichotomised craniofacial phenotypes were hypertelorism, macrocephaly and corpus callosum agenesis. All other phenotypes were registered, but not dichotomised.Pathogenic GLI3 variantsAll GLI3 variants were extracted and checked using Alamut Visual V.2.14. If indicated, variants were renamed according to standard Human Genome Variation Society nomenclature.20 Variants were grouped in either missense, frameshift, nonsense or splice site variants. In the group of frameshift variants, a subgroup with possible splice site effect were identified for subgroup analysis when indicated.

Similarly, nonsense variants prone for nonsense mediated decay (NMD) and nonsense variants with experimentally confirmed NMD were identified.21 Deletions of multiple exons, CNVs and translocations were excluded for analysis. A full list of included mutations is available in the online supplementary materials.Supplemental materialThe location of the variant was compared with five known structural domains of the GLI3 gene. (1) repressor domain, (2) zinc finger domain, (3) cleavage site, (4) activator domain, which we defined as a concatenation of the separately identified transactivation zones, the CBP binding domain and the mediator binding domain (MBD) and (5) the MID1 interaction region domain.1 6 22–24 The boundaries of each of the domains were based on available literature (figure 1, exact locations available in the online supplementary materials). The boundaries used by different authors did vary, therefore a consensus was made.In this figure the posterior probability of an anterior phenotype is plotted against the location of the variant, stratified for the type of mutation that was observed. For better overview, only variants with a location effect were displayed.

The full figure, including all variant types, can be found in the online supplementary figure 1. Each mutation is depicted as a dot, the size of the dot represents the number of observations for that variant. If multiple observations were made, the mean posterior odds and IQR are plotted.

Polytomous variable LCA, poLCA V.1.4.1.). We used our LCA to detect the number of phenotypic subgroups in the dataset and subsequently predict a class membership for each case in the dataset based on the posterior probabilities.In order to make a reliable prediction, only phenotypes that were sufficiently reported and/or ruled out were feasible for LCA, limiting the analysis to preaxial polydactyly, postaxial polydactyly and syndactyly of the hands and feet. Only full cases were included. To determine the optimal number of classes, we fitted a series of models ranging from a one-class to a six-class model.

The optimal number of classes was based on the conditional Akaike information criterion (cAIC), the non adjusted and the sample-size adjusted Bayesian information criterion (BIC and aBIC) and the obtained entropy.25 The explorative LCA produces both posterior probabilities per case for both classes and predicted class membership. Using the predicted class membership, the phenotypic features per class were determined in a univariate analysis (χ2, SPSS V.25). Using the posterior probabilities on latent class (LC) membership, a scatter plot was created using the location of the variant on the x-axis and the probability of class membership on the y-axis for each of the types of variants (Tibco Spotfire V.7.14). Using these scatter plots, variants that give similar phenotypes were clustered.Genotype/phenotype correlationBecause an LC has no clinical value, the correlation between genotypes and phenotypes was investigated using the predictor phenotypes and the clustered phenotypes. First, those phenotypes that contribute most to LC membership were identified.

Second those phenotypes were directly related to the different types of variants (missense, nonsense, frameshift, splice site) and their clustered locations. Quantification of the relation was performed using a univariate analysis using a χ2 test. Because of our selection criteria, meaning patients at least have two phenotypes, a multivariate using a logistic regression analysis was used to detect the most significant predictors in the overall phenotype (SPSS V.25). Finally, we explored the relation of the clustered genotypes to the presence of corpus callosum agenesis, a rare malformation in GLI3-mediated polydactyly syndromes which cannot be readily diagnosed without additional imaging.ResultsWe included 251 patients from the literature and 46 local patients,10–12 16 21 26–43 in total 297 patients from 155 different families with 127 different GLI3 variants, 32 of which were large deletions, CNVs or translocations. In six local cases, the exact variant could not be retrieved by status research.The distribution of the most frequently observed phenotypes and variants are presented in table 1.

Other recurring phenotypes included developmental delay (n=22), broad nasal root (n=23), frontal bossing or prominent forehead (n=16) and craniosynostosis (n=13), camptodactyly (n=8) and a broad first interdigital webspace of the foot (n=6).View this table:Table 1 Baseline phenotypes and genotypes of selected populationThe LCA model was fitted using the six defined hand/foot phenotypes. Model fit indices for the LCA are displayed in table 2. Based on the BIC, a two-class model has the best fit for our data. The four-class model does show a gain in entropy, http://www.ec-cigognes-oberschaeffolsheim.ac-strasbourg.fr/archives/continuite-pedagogique/cm2/semaine-du-27-avril-au-1er-mai/jeudi-30-avril/ however with a higher BIC and loss of df. Therefore, based on the majority of performance statistics and the interpretability of the model, a two-class model was chosen.

Table 3 displays the distribution of phenotypes and genotypes over the two classes.View this table:Table 2 Model fit indices for the one-class through six-class model evaluated in our LCAView this table:Table 3 Distribution of phenotypes and genotypes in the two latent classes (LC)Table 1 depicts the baseline phenotypes and genotypes in the obtained population. Note incomplete data especially in the cranium phenotypes. In total 259 valid genotypes were present. In total, 289 cases had complete data for all hand and foot phenotypes (preaxial polydactyly, postaxial polydactyly and syndactyly) and thus were available for LCA. Combined, for phenotype/genotype correlation 258 cases were available with complete genotypes and complete hand and foot phenotypes.Table 2 depicts the model fit indices for all models that have been fitted to our data.Table 3 depicts the distribution of phenotypes and genotypes over the two assigned LCs.

Hand and foot phenotypes were used as input for the LCA, thus are all complete cases. Malformation of the cranium and genotypes do have missing cases. Note that for the LCA, full case description was required, resulting in eight cases due to incomplete phenotypes. Out of these eight, one also had a genotype that thus needed to be excluded. Missingness of genotypic data was higher in LC2, mostly due to CNVs (table 1).In 54/60 cases, a missense variant produced a posterior phenotype.

Likewise, splice site variants show the same phenotype in 23/24 cases (table 3). For both frameshift and nonsense variants, this relation is not significant (52 anterior vs 54 posterior and 26 anterior vs 42 posterior, respectively). Therefore, only for nonsense and frameshift variants the location of the variant was plotted against the probability for LC2 membership in figure 1. A full scatterplot of all variants is available in online supplementary figure 1.Figure 1 reveals a pattern for these nonsense and frameshift variants that reveals that variants at the C-terminal of the gene predict anterior phenotypes. When relating the domains of the GLI3 protein to the observed phenotype, we observe that the majority of patients with a nonsense or frameshift variant in the repressor domain, the zinc finger domain or the cleavage site had a high probability of an LC2/anterior phenotype.

This group contains all variants that are either experimentally determined to be subject to NMD (triangle marker in figure 1) or predicted to be subject to NMD (diamond marker in figure 1). Frameshift and nonsense variants in the activator domain result in high probability for an LC1/posterior phenotype. These variants will be further referred to as truncating variants in the activator domain.The univariate relation of the individual phenotypes to these two groups of variants are estimated and presented in table 4. In our multivariate analysis, postaxial polydactyly of the foot and hand are the strongest predictors (Beta. 2.548, p<0001 and Beta.

1.47, p=0.013, respectively) for patients to have a truncating variant in the activator domain. Moreover, the effect sizes of preaxial polydactyly of the hand and feet (Beta. ˆ’0.797, p=0123 and −1.772, p=0.001) reveals that especially postaxial polydactyly of the foot is the dominant predictor for the genetic substrate of the observed anomalies.View this table:Table 4 Univariate and multivariate analysis of the phenotype/genotype correlationTable 4 shows exploration of the individual phenotypes on the genotype, both univariate and multivariate. The multivariate analysis corrects for the presence of multiple phenotypes in the underlying population.Although the craniofacial anomalies could not be included in the LCA, the relation between the observed anomalies and the identified genetic substrates can be studied. The prevalence of hypertelorism was equally distributed over the two groups of variants (47/135 vs 21/47 respectively, p<0.229).

However for corpus callosum agenesis and macrocephaly, there was a higher prevalence in patients with a truncating variant in the activator domain (3/75 vs 11/41, p<0.001. OR. 8.8, p<0.001) and 42/123 vs 24/48, p<0.05). Noteworthy is the fact that 11/14 cases with corpus callosum agenesis in the dataset had a truncating variant in the activator domain.DiscussionIn this report, we present new insights into the correlation between the phenotype and the genotype in patients with GLI3-mediated polydactyly syndromes. We illustrate that there are two LCs of patients, best predicted by postaxial polydactyly of the hand and foot for LC1, and the preaxial polydactyly of the hand and foot and syndactyly of the foot for LC2.

Patients with postaxial phenotypes have a higher risk of having a truncating variant in the activator domain of the GLI3 gene which is also related to a higher risk of corpus callosum agenesis. These results suggest a functional difference between truncating variants on the N-terminal and the C-terminal side of the GLI3 cleavage site.Previous attempts of phenotype to genotype correlation have not yet provided the clinical confirmation of these assumed mechanisms in the pathophysiology of GLI3-mediated polydactyly syndromes. Johnston et al have successfully determined the Pallister-Hall region in which truncating variants produce a Pallister-Hall phenotype rather than Greig syndrome.11 However, in their latest population study, subtypes of both syndromes were included to explain the full spectrum of observed malformations. In 2015, Demurger et al reported the higher incidence of corpus callosum agenesis in the Greig syndrome population with truncating mutations in the activator domain.12 Al-Qattan in his review summarises the concept of a spectrum of anomalies dependent on haplo-insufficiency (through different mechanisms) and repressor overexpression.13 However, he bases this theory mainly on reviewed experimental data. Our report is the first to provide an extensive clinical review of cases that substantiate the phenotypic difference between the two groups that could fit the suggested mechanisms.

We agree with Al-Qattan et al that a variation of anomalies can be observed given any pathogenic variant in the GLI3 gene, but overall two dominant phenotypes are present. A population with predominantly preaxial anomalies and one with postaxial anomalies. The presence of preaxial or postaxial polydactyly and syndactyly is not mutually exclusive for one of these two subclasses. Meaning that preaxial polydactyly can co-occur with postaxial polydactyly. However, truncating mutations in the activator domain produce a postaxial phenotype, as can be derived from the risk in table 4.

The higher risk of corpus callosum agenesis in this population shows that differentiating between a preaxial phenotype and a postaxial phenotype, instead of between the different GLI3-mediated polydactyly syndromes, might be more relevant regarding diagnostics for corpus callosum agenesis.We chose to use LCA as an exploratory tool only in our population for two reasons. First of all, LCA can be useful to identify subgroups, but there is no ‘true’ model or number of subgroups you can detect. The best fitting model can only be estimated based on the available measures and approximates the true subgroups that might be present. Second, LC membership assignment is a statistical procedure based on the posterior probability, with concordant errors of the estimation, rather than a clinical value that can be measured or evaluated. Therefore, we decided to use our LCA only in an exploratory tool, and perform our statistics using the actual phenotypes that predict LC membership and the associated genotypes.

Overall, this method worked well to differentiate the two subgroups present in our dataset. However, outliers were observed. A qualitative analysis of these outliers is available in the online supplementary data.The genetic substrate for the two phenotypic clusters can be discussed based on multiple experiments. Overall, we hypothesise two genetic clusters. One that is due to haploinsufficiency and one that is due to abnormal truncation of the activator.

The hypothesised cluster of variants that produce haploinsufficiency is mainly based on the experimental data that confirms NMD in two variants and the NMD prediction of other nonsense variants in Alamut. For the frameshift variants, it is also likely that the cleavage of the zinc finger domain results in functional haploinsufficiency either because of a lack of signalling domains or similarly due to NMD. Missense variants could cause haploinsufficiency through the suggested mechanism by Krauss et al who have illustrated that missense variants in the MID1 domain hamper the functional interaction with the MID1-α4-PP2A complex, leading to a subcellular location of GLI3.24 The observed missense variants in our study exceed the region to which Krauss et al have limited the MID-1 interaction domain. An alternative theory is suggested by Zhou et al who have shown that missense variants in the MBD can cause deficiency in the signalling of GLI3A, functionally implicating a relative overexpression of GLI3R.22 However, GLI3R overexpression would likely produce a posterior phenotype, as determined by Hill et al in their fixed homo and hemizygous GLI3R models.15 Therefore, our hypothesis is that all included missense variants have a similar pathogenesis which is more likely in concordance with the mechanism introduced by Krauss et al. To our knowledge, no splice site variants have been functionally described in literature.

However, it is noted that the 15 and last exon encompasses the entire activator domain, thus any splice site mutation is by definition located on the 5′ side of the activator. Based on the phenotype, we would suggest that these variants fail to produce a functional protein. We hypothesise that the truncating variants of the activator domain lead to overexpression of GLI3R in SHH rich areas. In normal development, the presence of SHH prevents the processing of full length GLI34 into GLI3R, thus producing the full length activator. In patients with a truncating variant of the activator domain of GLI3, thus these variants likely have the largest effect in SHH rich areas, such as the ZPA located at the posterior side of the hand/footplate.

Moreover, the lack of posterior anomalies in the GLI3∆699/- mouse model (hemizygous fixed repressor model) compared with the GLI3∆699/∆699 mouse model (homozygous fixed repressor model), suggesting a dosage effect of GLI3R to be responsible for posterior hand anomalies.15 These findings are supported by Lewandowski et al, who show that the majority of the target genes in GLI signalling are regulated by GLI3R rather than GLI3A.44 Together, these findings suggest a role for the location and type of variant in GLI3-mediated syndromes.Interestingly, the difference between Pallister-Hall syndrome and GLI3-mediated polydactyly syndromes has also been attributed to the GLI3R overexpression. However, the difference in phenotype observed in the cases with a truncating variant in the activator domain and Pallister-Hall syndrome suggest different functional consequences. When studying figure 1, it is noted that the included truncating variants on the 3′ side of the cleavage site seldomly affect the CBP binding region, which could provide an explanation for the observed differences. This binding region is included in the Pallister-Hall region as defined by Johnston et al and is necessary for the downstream signalling with GLI1.10 11 23 45 Interestingly, recent reports show that pathogenic variants in GLI1 can produce phenotypes concordant with Ellis von Krefeld syndrome, which includes overlapping features with Pallister-Hall syndrome.46 The four truncating variants observed in this study that do affect the CBP but did not result in a Pallister-Hall phenotype are conflicting with this theory. Krauss et al postulate an alternative hypothesis, they state that the MID1-α4-PP2A complex, which is essential for GLI3A signalling, could also be the reason for overlapping features of Opitz syndrome, caused by variants in MID1, and Pallister-Hall syndrome.

Further analysis is required to fully appreciate the functional differences between truncating mutations that cause Pallister-Hall syndrome and those that result in GLI3-mediated polydactyly syndromes.For the clinical evaluation of patients with GLI3-mediated polydactyly syndromes, intracranial anomalies are likely the most important to predict based on the variant. Unfortunately, the presence of corpus callosum agenesis was not routinely investigated or reported thus this feature could not be used as an indicator phenotype for LC membership. Interestingly when using only hand and foot phenotypes, we did notice a higher prevalence of corpus callosum agenesis in patients with posterior phenotypes. The suggested relation between truncating mutations in the activator domain causing these posterior phenotypes and corpus callosum agenesis was statistically confirmed (OR. 8.8, p<0.001).

Functionally this relation could be caused by the GLI3-MED12 interaction at the MBD. Pathogenic DNA variants in MED12 can cause Opitz-Kaveggia syndrome, a syndrome in which presentation includes corpus callosum agenesis, broad halluces and thumbs.47In conclusion, there are two distinct phenotypes within the GLI3-mediated polydactyly population. Patients with more posteriorly and more anteriorly oriented hand anomalies. Furthermore, this difference is related to the observed variant in GLI3. We hypothesise that variants that cause haploinsufficiency produce anterior anomalies of the hand, whereas variants with abnormal truncation of the activator domain have more posterior anomalies.

Furthermore, patients that have a variant that produces abnormal truncation of the activator domain, have a greater risk for corpus callosum agenesis. Thus, we advocate to differentiate preaxial or postaxial oriented GLI3 phenotypes to explain the pathophysiology as well as to get a risk assessment for corpus callosum agenesis.Data availability statementData are available upon reasonable request.Ethics statementsPatient consent for publicationNot required.Ethics approvalThe research protocol was approved by the local ethics board of the Erasmus MC University Medical Center (MEC 2015-679)..

Antabuse and vanilla extract

If your days consist of inadequate sleep, excessive screen time, and little to no physical http://2018.swissbiotechday.ch/canadian-levitra-online activity, then you might be harming your antabuse and vanilla extract health in more ways than one. Although these factors are commonly known to be detrimental to an individual’s physical and emotional health, they have an impact on your cognitive health, too.Cognitive health, or the ability to think, learn, and remember well, is crucial in everyday function. Something as antabuse and vanilla extract basic as communicating with another person, paying attention, or remembering information involves different types of cognitive processes that occur unconsciously. You might think it’s too early to be concerned about your cognition, but research shows that engaging in mentally stimulating activities throughout your life is associated with slower late-life cognitive decline.Contrary to what they claim, computer-based cognitive-training software, or popular brain training mobile applications, aren’t scientifically proven to delay cognitive decline or protect against mild cognitive impairment. Here are antabuse and vanilla extract five activities that you can do instead.1.

Language LearningLearning a new language comes with cognitive benefits because it is a complex process that stimulates different areas of the brain, says David Copeland, an associate professor of psychology and director of the Reasoning and Memory Lab at the University of Nevada, Las Vegas. Getting to know the syntax and semantics of another language, forming new grammar structures and acquiring vocabulary all require immense and consistent mental effort.A 2019 study found that a four-month-long language learning program may preserve brain plasticity and improve mental functioning in aging individuals. Additionally, intense language studies can increase cortical thickness and hippocampal volumes of the brain, which are associated with general intelligence and declarative memory performance.People often antabuse and vanilla extract assume that knowing more than one language will confuse the brain and complicate cognitive development. In reality, actively utilizing two or more languages helps you protect your brain against cognitive decline.2. MeditationNumerous studies have investigated the antabuse and vanilla extract effects of meditation on cognition, and a 2014 systematic review suggests that it may offset age-related cognitive decline.

Different brain regions get activated when you meditate, including the neural structures involved in attention, which might explain why four to five days of meditation training can enhance the ability to concentrate on a specific stimulus while tuning out other distractions. Moreover, research suggests that long-term meditators have more folds in the outer layer of their brain compared to those who don’t meditate, potentially increasing their ability to process information.3. Physical ActivityNot only does regular exercise boost physical fitness and prevent chronic diseases, but it can also improve antabuse and vanilla extract brain health. A 2011 study found that exercise training may improve memory function because it increases the size of the hippocampus, the part of the brain involved in forming and storing new memories. In addition, antabuse and vanilla extract a 2017 study demonstrates that physical activity also increases cerebral glucose metabolism in the brain regions that are important for learning and memory, possibly helping combat Alzheimer's disease.A rich body of research demonstrates how physical fitness prevents cognitive decline, and that many different mechanisms are thought to be at play.

Promoting neuroplasticity, improving vascular health — a factor that affects cognitive function — and stimulating brain growth factors involved in protecting or increasing neuron health, may be behind these exercise-induced benefits, says Laura D. Baker, professor of internal medicine, neurology, and public health sciences at Wake Forest School of Medicine.4. Leisure ReadingThe act of reading is a cognitive process involving comprehension, deductive antabuse and vanilla extract reasoning and critical analysis, which activates several areas in the brain and keeps you mentally stimulated. According to a 14-year longitudinal study, reading at least twice a week is associated with a reduced risk of cognitive decline. The researchers also suggested that reading may increase cognitive capital to resist aging-related loss antabuse and vanilla extract of cognitive function.

Although more research is needed to assess whether reading directly prevents cognitive impairment, engaging in intellectually stimulating activities can slow age-related decline in memory and thinking abilities. 5. Social Activity“Social interaction is believed to antabuse and vanilla extract be as important to brain health as is cognitive stimulation,” Baker says. €œIt is another form of enrichment that can lead to increased brain activity in regions critical for memory and attention.” Research shows that having a socially active lifestyle in late life delays memory loss and protects against dementia and Alzheimer's disease. The increased social and emotional support may enhance cognitive performance as well.Having a small social network and infrequent social interaction, otherwise known as social isolation, is associated with decreased cognitive antabuse and vanilla extract function and increased memory decline.

It also increases the risk of depression, a condition that can reduce cognitive performance and impair memory. Therefore, maintaining regular interaction with your social network through get-togethers and phone or video calls is crucial for your health.“Because our brains evolved as social animals, we typically need social interactions for healthy brain stimulation,” Copeland says. €œConversations are much more complex than we think they are.”The healthy antabuse and vanilla extract infant gut is an ecosystem much like a healthy ocean, and it's filled with trillions of microscopic bacteria. When environmental factors interfere with the natural balance — just as pollution does in the sea — this impacts the body’s ability to function at its best. Today, U.S antabuse and vanilla extract.

Babies’ guts are less diverse than they used to be. Lacking a rich stew of microbial bacteria in infancy has been linked to autoimmune diseases such as type 1 diabetes, Crohn’s and celiac, as well as colic, asthma, eczema, and allergies, according to a June 2021 study published in Cell. Naturally, an infant’s microbiome is influenced by their mother’s, research shows, but antabuse and vanilla extract external factors also play a role. Over the past five decades, antibiotic use and C-sections have increased while rates of certain diseases have also jumped rapidly — suggesting environmental and societal factors influence the gut, not just genetics. For example, babies born in antabuse and vanilla extract the U.S.

Lack some of the beneficial bacteria found in the guts of those born in less industrialized countries, researchers reported in a 2019 Nature paper. €œWe are changing the transmission of the microbiome from generation to generation because of C-sections, early-life antibiotics and not breastfeeding at the most critical period of life,” says Martin J. Blaser, a microbiologist at Rutgers University and author of antabuse and vanilla extract Missing Microbes. How the Overuse of Antibiotics is Fueling our Modern Plagues.Early exposure to antibiotics increases babies’ risk of childhood asthma, allergies, eczema, celiac disease, obesity and attention deficit hyperactivity disorder, according to a January 2021 article from Mayo Clinic Proceedings. Blaser, who was involved with the study of nearly 14,600 children, said researchers found these risks increased when antabuse and vanilla extract babies received antibiotics in the first six months of life.

And with multiple courses of antibiotics, subjects were more likely to develop certain conditions. Another study, published in Science Translational Medicine in 2016, found antibiotic use and C-section delivery resulted in babies with less stable and less diverse gut bacteria, which had long-term health effects. In the U.S., nearly one in three babies is born antabuse and vanilla extract via C-section. In Brazil, C-section procedures account for some 56 percent of births, with rates even higher in urban areas. And in the Dominican Republic, 58 percent antabuse and vanilla extract of births occurred through C-section, reports the World Health Organization.It turns out that vaginal deliveries protect babies from harmful bacteria because they receive beneficial bacteria from their mothers to launch, or seed, their body’s developing microbiome, says Karl Sylvester, a pediatric surgeon at Stanford Children’s Health.What Can Parents Do?.

If possible, mothers can try to avoid C-sections and giving their babies antibiotics, along with breastfeeding exclusively for the first six months of life. Breastfeeding infants get beneficial bacteria from skin contact and the mother’s milk. What about antabuse and vanilla extract babies’ ear s or breastfeeding moms’ mastitis?. For decades, doctors prescribed antibiotics reasoning that while it may not help, it won’t hurt, Blaser says. Additionally, not antabuse and vanilla extract all ear s require antibiotics.

Not only has their frequent prescription resulted in antibiotic-resistant bacteria, but it has also reduced the beneficial bacteria that serves as the foundation to human health. Studies also show the earlier and the more often babies were exposed to antibiotics, the more likely they were to develop asthma or a milk allergy, he says. Yet it's standard practice to antabuse and vanilla extract give infants antibiotic eye drops at birth in the U.S. And Europe to prevent vaginal transmission of an such as chlamydia or gonorrhea, a bacterial that, untreated, causes blindness, says Maria Gloria Dominguez-Bello, a microbiologist at Rutgers University. Even when babies are delivered by C-section and therefore not exposed to potential , medical staff still administers the antabuse and vanilla extract antibiotics to infants, she says.And when mothers are prescribed antibiotics while pregnant or nursing, it reaches the baby.

With proper knowledge, nursing mothers can prevent mastitis and try non-medical treatments before turning to an antibiotic, according to the American Academy of Family Physicians. Breastfeeding is still preferable to formula, Sylvester and Blaser say, because even with antibiotic use, human milk still nourishes beneficial bacteria — but formula contains none.The Pros of Probiotics Sometimes, C-sections and antibiotics can’t be avoided and parents consider probiotics or prebiotics. €œThe infant microbiome is not set in stone at antabuse and vanilla extract the time of birth,” says Karin B. Michels, epidemiologist at the UCLA Fielding School of Public Health. €œYou still have time to try to optimize it.” Probiotics vary widely in proven efficacy, and some are essentially a modern form of snake oil, says George Weinstock, director of microbial genomics at The Jackson Laboratory antabuse and vanilla extract.

That said, in a study involving infants at high risk for type 1 diabetes, those given over-the-counter probiotics in the first 27 days of life had a lower rate of developing the disease than those who didn’t take a probiotic, he says. €œIf you seed the microbiome right at the beginning with something potentially beneficial, you can reduce autoimmune disease,” Weinstock says. While it’s not yet common medical practice, two separate papers showed that providing breastfeeding infants antabuse and vanilla extract with specific probiotics had beneficial impacts on their gut health. In a double-blind 2018 Pediatrics study involving breastfeeding infants with colic, babies who received the probiotic Lactobacillus reuteri were nearly twice less likely to fuss and cry than the babies who took a placebo. But there were no significant antabuse and vanilla extract differences in crying and fussing between formula-fed babies who received the probiotic versus the placebo.

In another study, which was published in Cell in July 2021, breastfed infants ingested the probiotic Bifidobacterium infantis (B. Infantis), which is naturally found in the guts of infants living in countries where autoimmune diseases are low, such as Bangladesh and Malawi, but rarely found in infants’ guts in Europe or North America. The Cell antabuse and vanilla extract study showed B. Infantis EVC001 grew successfully in the guts of infants who received it. It consumes antabuse and vanilla extract nutrients in breast milk, and multiplies to crowd out “bad” bacteria that cause inflammation.

However, several of the authors are affiliated with a probiotic company.Still, the recent studies of B. Infantis are credible, says Tommi Vatanen, an infant gut microbiome researcher with The Auckland University in New Zealand who was not involved with the Cell study of B. Infantis EVC001. €œThat’s super compelling evidence that’s generated some buzz.”Research also shows that a practice called “vaginal seeding,” in which a nurse swabs the mother’s perinatal area with gauze and wipes it on the newborn, allows bacteria to grow on the babies’ body and helps their microbiome reflect those of babies born vaginally, says Dominguez-Bello. €œHowever, does this microbial restoration normalize disease risk?.

We have not done the randomized clinical trials to demonstrate whether this would be the case, as we hypothesize.” Similar to how some doctors and nurses opt out of the antibiotic eye drops for their babies, researchers who study the microbiome may perform vaginal seeding. When their babies are delivered by emergency C-sections, these scientists often smear their baby with vaginal fluid at birth, Michels says. €œIt’s not going to harm the child.” Michels, who studies the role nutrition plays in health, advises mothers to eat a healthy diet while pregnant and breastfeeding, and to avoid environmental pollutants. After all, babies are what their mothers eat. For example, infants whose mothers avoided peanuts while pregnant are more likely to develop a peanut allergy, she says.

Parents shouldn’t beat themselves up if they had a C-section, gave their baby antibiotics or used formula, researchers say. There’s a tremendous amount of research underway, Weinstock says. €œThese are early days.” “The microbiome is not everything. Genetics dominates almost everything,” Michels says. €œThe microbiome is one coordinate in determining our future, but it’s not the only one.” This story has been updated to include additional information from Dominguez-Bello.When Randy Gardner entered his high school science fair in 1963, he wanted to do something big.

His idea was to top the world record for sleep deprivation by staying awake for exactly 11 days. He accomplished this feat with the help of two friends, but the 264-hour “wake-a-thon” caused Gardner to experience the disturbing symptoms of sleep deprivation. Memory problems, decreased motor skills, and even hallucinations. Many of us have experienced some version of sleep deprivation — an all-nighter to finish an assignment or a late night out. The next day we feel sleepy, sluggish, and irritable.

But what happens when sleepless nights accumulate into two, four, or even 11 nights?. Sleep, despite its ubiquity among humans and other animals, remains a mystery to scientists. €œI’m fascinated by sleep because it occupies so much of our lives and yet it’s not fully understood,” says Brendan Lucey, associate professor of neurology and director of the Division of Sleep Medicine at Washington University in St. Louis, Missouri. Lucey says that while scientists don’t know exactly why sleep evolved, they theorize that its role in brain function, memory consolidation, and metabolism has led to its conservation across species.

We spend about a third of our lives sleeping, and we know sleep is essential by looking at what happens when we go without it. The loss in coordination and good judgment after just one sleepless night is comparable to that observed in a person with a blood alcohol level of .10 percent, above the legal limit for driving in most states. As sleepless nights accumulate, we exhibit increasingly stranger symptoms.24 hours. You may know that one night of lost sleep can cause fatigue, mental fog, tremors, irritability and reduced coordination. This slight deprivation also decreases blood flow and metabolism in the prefrontal cortex of the brain (the one responsible for higher reasoning like attention, problem solving, and decision making).

Our sense of smell is connected to this region, and one study found that after 24 hours of wakefulness people had trouble distinguishing between common smells like pizza, pineapple, and grass.48 hours. At two days without sleep, the body begins to experience physical symptoms of sleep loss. The immune system is impacted. Natural killer cells (responsible for fighting tumors and antabusees) decrease by 37 percent after just 48 hours of wakefulness, according to one study. Visual hallucinations can also manifest — prolonged wakefulness causes images to form incorrectly on our retinas.

These may be as benign as believing the room is larger than it is, or as frightening as the sudden appearance of an imaginary person or animal. 72 hours. At this point, your body will start finding ways to force you into unconsciousness. Microsleeps are involuntary bursts of sleep lasting between 1 and 30 seconds. Often, you don’t know you’re having them.

They can be dangerous if you happen to be driving, but you’ve probably experienced a more innocuous microsleep if you’ve ever nodded off during class or a meeting. Other forced sleep shows up on EEG readings. Delta waves (those associated with deep sleep) have been detected in the brains of severely sleep-deprived, yet completely conscious, humans. 96 hours and beyond. You may slip into a state resembling psychosis at this stage.

You could experience delusions, imagining that your neighbor is plotting your death, or becoming convinced you’re on a secret military mission. Imagined sounds and sensations of touch creep into your consciousness. You may feel detached from yourself and others, a condition called depersonalization. You can no longer correctly interpret your reality. Does Sleep Deprivation Kill?.

Luckily, severely sleep-deprived people can fully recover from these symptoms with a good night’s rest. But what if sleep deprivation continues indefinitely?. Gardner perhaps demonstrated the upper limits of sleep deprivation that humans can withstand, but a rare genetic disorder called fatal familial insomnia (FFI) pushes past that threshold. Affecting less than one person per million each year, FFI is a prion disease characterized by a buildup of misfolded proteins in the brain. Beginning with mild insomnia in middle age, the disease rapidly progresses to complete sleep loss followed by deterioration of brain regions responsible for essential functions like breathing and temperature regulation, resulting in coma and death.How to Get Better Sleep While mild sleep deprivation won’t kill you, it can have harmful effects on health.

€œSleep is enrolled in a lot of systems” in the body, says Lucey. Insomnia, obstructive sleep apnea, and shift work are common causes of sleep deficiency and have been associated with a greater risk of heart disease, high blood pressure, type-2 diabetes, obesity, and Alzheimer’s disease. So, what can you do to get proper shuteye?. Sara Benjamin, a clinical associate at the Johns Hopkins Center for Sleep, helps people overcome sleep problems. After identifying and treating physiological sleep disorders, Benjamin says good sleep boils down to routine.

€œMost people do best with a set schedule,” she says. That means going to bed and waking up at the same time every day. Also important, Benjamin says, is having a wind-down period before bed. A time when you stop doing productive things, put down your screens, and begin to relax. €œThere are so many things that we regiment in our lives, and you have to look at sleep as just as important as whatever else you're doing for your health.” In 1989, the Guinness Book of World Records discontinued the longest time without sleep category, citing health concerns for the participant.

Though others have since broken his record, Gardner’s 264 hours without sleep stands as the last official entry.To scientists' surprise, more than 80 percent of Iowa's wild and captive white-tailed deer population tested positive for alcoholism (the antabuse that causes alcoholism treatment in humans) between late November 2020 and January of this year. This revelation comes from a study posted to the pre-print server bioRxiv earlier this month. The percentage of positive samples increased throughout the course of the study, and one-third of the 283 samples ultimately tested positive.“Our studies show that while we were distracted with the antabuse in human populations during the winter months of 2020 and 2021, an outbreak of alcoholism was silently spreading amongst the deer herd quite unbeknownst to us,” says Suresh Kuchipudi, a co-author of the article and a clinical professor of veterinary and biomedical sciences at Pennsylvania State University. The authors note that the white-tailed deer, who is instantly recognizable to fans of Disney's Bambi, is the country's most popular wild deer species. Around 25 million call the U.S.

Home. The discovery that a significant portion of this population is also vulnerable to alcoholism now raises questions about the potential for an evolved version of the alcoholism to jump back into humans — which increases the likelihood that alcoholism treatment won't be wiped out completely and could instead become endemic, or a regular occurrence like the cold and flu.Caught in the HeadlightsThe idea to extract the lymph nodes, which are located in the head and neck, from hundreds of deer and test them for active didn’t come out of thin air. For one, these samples were already being collected by the Iowa Department of Natural Resources as part of its routine, statewide Chronic Wasting Disease surveillance program. But perhaps more importantly, previous studies had already identified the deer's elevated risk of contracting alcoholism.That's because the angiotensin-converting enzyme 2, or ACE2 receptor, of several animals bonds notably well with alcoholism, according to research published in the ​​Proceedings of the National Academy of Sciences in 2020. The alcoholism is extremely adept at attacking the ACE2 receptor in humans, as well as in other primates.

But the researchers were surprised to find that three species of deer, including white-tailed deer, were particularly vulnerable as well.“That's why people started to look at deer,” says Tony Goldberg, an epidemiology professor at the University of Wisconsin-Madison School of Veterinary Medicine who was not involved in the studies. €œIt wasn't because they were getting sick — deer weren't showing up for alcoholism treatment vaccinations. It was because the scientific community predicted that they would be susceptible.”This year, studies demonstrated that white-tailed deer could be inoculated with the antabuse and transmit it to one another, and that a large portion of the animal's U.S. Population had already developed antibodies against alcoholism. But the presence of antibodies, though indicative of indirect exposure to the alcoholism, didn't actually prove that the deer were actively becoming infected.The key evidence.

Recent genome sequencing conducted by Kuchipudi and other researchers at Penn State showed that alcoholism was present in white-tailed deer. This sequencing also indicated that related groups of antabuse variants found in the animals mapped closely to those circulating in human Iowans at that time, says Vivek Kapur, a professor of microbiology and infectious diseases at Pennsylvania State University and co-author of the most recent study. The patterns of genetic variation they observed strongly suggest that multiple independent spillover events traveled from humans to the deer, he adds.“More people on public lands, limited food sources for the deer during the winter time, hunting-related disruption of deer movement and high burden among humans may all have contributed to the very high positivity rate we observed in the deer samples,” Kuchipudi says.In fact, the peak positivity rate among deer samples coincided very closely with both the Iowa hunting season and the peak rate among people in the state. Over 80 percent of deer samples were positive during late November through January. €œWe don't know [how because] it does seem like it's unusual for people to be breathing within six feet of a deer,” Goldberg says.

€œThere may be a role for contamination of inanimate objects. So if I have alcoholism treatment and I'm hunting deer or walking in the woods and I sneeze a big snot glob on a leaf, and a deer comes by a few hours later and sniffs it, that might do it.” He notes that researchers have speculated about other modes of transmission as well, such as through contaminated wastewater.The Reservoir That Won’t Run DryThe antabuse will likely stick around the new environment offered by deer, Goldberg says, and other experts share this view. €œConsidering how quickly it's been spreading among deer, the fact that they don't seem to be symptomatic, and the fact that the researchers found it in the lymph nodes of deer — which is usually indicative of a antabuse that has staying power — it's probably not going away anytime soon,” he says.Although the deer appear to be asymptomatic for now, researchers worry the alcoholism could continue to evolve as it passes from deer to deer and could eventually return to humans as something far more virulent and evasive of our natural (and vaccinated) immunity.Additionally, other wildlife that interact with deer are also at risk. €œSince deer are now identified as the second known free-living reservoir host for this antabuse, our studies highlight an urgent need to carry out comprehensive alcoholism surveillance of white-tailed deer together with other susceptible animals such as deer, mice [and] skunks,” Kapur says.In epidemiology, reservoirs are defined as populations or environments in which an infectious pathogen survives and thrives. We discovered that mink, for example, are susceptible to the antabuse when every mink in Denmark — a total surpassing 12 million from more than 200 farms — was culled over fears of alcoholism treatment late last year.

Wild mink are also widespread throughout much of North America, but so far only one has been found to be infected. Ultimately, the more animal reservoirs for the alcoholism, the more opportunities it has to evolve into something even more harmful. Within the next six months, Goldberg expects researchers to have a much clearer idea of where alcoholism has spread within the U.S. Deer population.Changing the Game PlanSo far, there’s no evidence that the antabuse can be transmitted from deer to humans, but it remains a concern.In fact, we have proof of infectious disease spreading from animals to humans. Each year, a few unlucky people contract plague from infected prairie dogs, for example.

But the National Wildlife Health Center successfully reduced the mortality from plague in four species of prairie dogs in seven states by distributing peanut butter-flavored, treatment-laden bait near burrows. The scientists incorporated a harmless dye that changed the color of the prairie dogs’ hair and whiskers under UV light, so they were able to determine that about 70 percent of the animals took the bait.Read More. Self-Spreading Animal treatments Could Combat Human antabusesSimilar efforts have attempted to combat rabies. Earlier this year, for example, more than 500,000 baits containing the oral rabies treatment were dropped from aircraft in parts of North Carolina, with the intent of reducing the disease within raccoon populations. Although technologies for vaccinating wildlife exist, these endeavors are often difficult and expensive.

So far, there are no such plans for white-tailed deer and the novel alcoholism.Because the transmission of alcoholism within deer populations depends on direct contact within dense herds, says Goldberg, one possible strategy for slowing the spread of the antabuse might be to thin those herds through changes to hunting practices. And for many hunters, deer season begins this month. Recommendations from the U.S. Department of Agriculture so far include prohibiting contact between wildlife and domestic animals such as hunting dogs, avoiding any game that is found dead, and wearing gloves and a mask while processing it.While hunting practices may have contributed to the problem, they just might become part of the solution..

Social Activity“Social interaction is believed to be as important to brain health antabuse 250mg online as is cognitive stimulation,” Baker says. €œIt is another form of enrichment that can lead to increased brain activity in regions critical for memory and attention.” Research shows that having a socially active lifestyle in late life delays memory loss and protects against dementia and Alzheimer's disease.

The increased social and emotional support may enhance cognitive performance as well.Having a antabuse 250mg online small social network and infrequent social interaction, otherwise known as social isolation, is associated with decreased cognitive function and increased memory decline. It also increases the risk of depression, a condition that can reduce cognitive performance and impair memory. Therefore, maintaining regular interaction with your social network through get-togethers and phone or video calls is crucial for your health.“Because our brains evolved as social animals, we typically need social interactions for healthy brain stimulation,” Copeland says. €œConversations are much more complex than antabuse 250mg online we think they are.”The healthy infant gut is an ecosystem much like a healthy ocean, and it's filled with trillions of microscopic bacteria.

When environmental factors interfere with the natural balance — just as pollution does in the sea — this impacts the body’s ability to function at its best. Today, U.S antabuse 250mg online. Babies’ guts are less diverse than they used to be. Lacking a rich stew of microbial bacteria in infancy has been linked to autoimmune diseases such as type 1 diabetes, Crohn’s and celiac, as well as colic, asthma, eczema, and allergies, according to a June 2021 study published in Cell.

Naturally, an infant’s microbiome is influenced by their mother’s, research shows, but external factors also antabuse 250mg online play a role. Over the past five decades, antibiotic use and C-sections have increased while rates of certain diseases have also jumped rapidly — suggesting environmental and societal factors influence the gut, not just genetics. For example, antabuse 250mg online babies born in the U.S. Lack some of the beneficial bacteria found in the guts of those born in less industrialized countries, researchers reported in a 2019 Nature paper.

€œWe are changing the transmission of the microbiome from generation to generation because of C-sections, early-life antibiotics and not breastfeeding at the most critical period of life,” says Martin J. Blaser, a microbiologist antabuse 250mg online at Rutgers University and author of Missing Microbes. How the Overuse of Antibiotics is Fueling our Modern Plagues.Early exposure to antibiotics increases babies’ risk of childhood asthma, allergies, eczema, celiac disease, obesity and attention deficit hyperactivity disorder, according to a January 2021 article from Mayo Clinic Proceedings. Blaser, who was involved with the study of nearly 14,600 children, said researchers found these risks antabuse 250mg online increased when babies received antibiotics in the first six months of life.

And with multiple courses of antibiotics, subjects were more likely to develop certain conditions. Another study, published in Science Translational Medicine in 2016, found antibiotic use and C-section delivery resulted in babies with less stable and less diverse gut bacteria, which had long-term health effects. In the U.S., nearly one in three babies antabuse 250mg online is born via C-section. In Brazil, C-section procedures account for some 56 percent of births, with rates even higher in urban areas.

And in the Dominican Republic, 58 percent of births occurred through C-section, reports the World Health Organization.It turns out that vaginal deliveries protect babies from harmful bacteria because they receive beneficial bacteria from their mothers to launch, or seed, their body’s developing microbiome, says Karl Sylvester, a pediatric surgeon antabuse 250mg online at Stanford Children’s Health.What Can Parents Do?. If possible, mothers can try to avoid C-sections and giving their babies antibiotics, along with breastfeeding exclusively for the first six months of life. Breastfeeding infants get beneficial bacteria from skin contact and the mother’s milk. What about babies’ antabuse 250mg online ear s or breastfeeding moms’ mastitis?.

For decades, doctors prescribed antibiotics reasoning that while it may not help, it won’t hurt, Blaser says. Additionally, not all ear s require antibiotics antabuse 250mg online. Not only has their frequent prescription resulted in antibiotic-resistant bacteria, but it has also reduced the beneficial bacteria that serves as the foundation to human health. Studies also show the earlier and the more often babies were exposed to antibiotics, the more likely they were to develop asthma or a milk allergy, he says.

Yet it's antabuse 250mg online standard practice to give infants antibiotic eye drops at birth in the U.S. And Europe to prevent vaginal transmission of an such as chlamydia or gonorrhea, a bacterial that, untreated, causes blindness, says Maria Gloria Dominguez-Bello, a microbiologist at Rutgers University. Even when babies are delivered by C-section and therefore not exposed to potential , medical staff still administers antabuse 250mg online the antibiotics to infants, she says.And when mothers are prescribed antibiotics while pregnant or nursing, it reaches the baby. With proper knowledge, nursing mothers can prevent mastitis and try non-medical treatments before turning to an antibiotic, according to the American Academy of Family Physicians.

Breastfeeding is still preferable to formula, Sylvester and Blaser say, because even with antibiotic use, human milk still nourishes beneficial bacteria — but formula contains none.The Pros of Probiotics Sometimes, C-sections and antibiotics can’t be avoided and parents consider probiotics or prebiotics. €œThe infant microbiome is not set in stone at the time of birth,” antabuse 250mg online says Karin B. Michels, epidemiologist at the UCLA Fielding School of Public Health. €œYou still have time to try to optimize it.” Probiotics vary widely in proven efficacy, and some are essentially a modern form of snake oil, says George Weinstock, director of microbial genomics at The antabuse 250mg online Jackson Laboratory.

That said, in a study involving infants at high risk for type 1 diabetes, those given over-the-counter probiotics in the first 27 days of life had a lower rate of developing the disease than those who didn’t take a probiotic, he says. €œIf you seed the microbiome right at the beginning with something potentially beneficial, you can reduce autoimmune disease,” Weinstock says. While it’s antabuse 250mg online not yet common medical practice, two separate papers showed that providing breastfeeding infants with specific probiotics had beneficial impacts on their gut health. In a double-blind 2018 Pediatrics study involving breastfeeding infants with colic, babies who received the probiotic Lactobacillus reuteri were nearly twice less likely to fuss and cry than the babies who took a placebo.

But there were no significant differences in crying and fussing between formula-fed babies who received the probiotic antabuse 250mg online versus the placebo. In another study, which was published in Cell in July 2021, breastfed infants ingested the probiotic Bifidobacterium infantis (B. Infantis), which is naturally found in the guts of infants living in countries where autoimmune diseases are low, such as Bangladesh and Malawi, but rarely found in infants’ guts in Europe or North America. The Cell antabuse 250mg online study showed B.

Infantis EVC001 grew successfully in the guts of infants who received it. It consumes nutrients in breast milk, and multiplies to crowd out “bad” antabuse 250mg online bacteria that cause inflammation. However, several of the authors are affiliated with a probiotic company.Still, the recent studies of B. Infantis are credible, says Tommi Vatanen, an infant gut microbiome researcher with The Auckland University in New Zealand who was not involved with the Cell study of B.

Infantis EVC001. €œThat’s super compelling evidence that’s generated some buzz.”Research also shows that a practice called “vaginal seeding,” in which a nurse swabs the mother’s perinatal area with gauze and wipes it on the newborn, allows bacteria to grow on the babies’ body and helps their microbiome reflect those of babies born vaginally, says Dominguez-Bello. €œHowever, does this microbial restoration normalize disease risk?. We have not done the randomized clinical trials to demonstrate whether this would be the case, as we hypothesize.” Similar to how some doctors and nurses opt out of the antibiotic eye drops for their babies, researchers who study the microbiome may perform vaginal seeding.

When their babies are delivered by emergency C-sections, these scientists often smear their baby with vaginal fluid at birth, Michels says. €œIt’s not going to harm the child.” Michels, who studies the role nutrition plays in health, advises mothers to eat a healthy diet while pregnant and breastfeeding, and to avoid environmental pollutants. After all, babies are what their mothers eat. For example, infants whose mothers avoided peanuts while pregnant are more likely to develop a peanut allergy, she says.

Parents shouldn’t beat themselves up if they had a C-section, gave their baby antibiotics or used formula, researchers say. There’s a tremendous amount of research underway, Weinstock says. €œThese are early days.” “The microbiome is not everything. Genetics dominates almost everything,” Michels says.

€œThe microbiome is one coordinate in determining our future, but it’s not the only one.” This story has been updated to include additional information from Dominguez-Bello.When Randy Gardner entered his high school science fair in 1963, he wanted to do something big. His idea was to top the world record for sleep deprivation by staying awake for exactly 11 days. He accomplished this feat with the help of two friends, but the 264-hour “wake-a-thon” caused Gardner to experience the disturbing symptoms of sleep deprivation. Memory problems, decreased motor skills, and even hallucinations.

Many of us have experienced some version of sleep deprivation — an all-nighter to finish an assignment or a late night out. The next day we feel sleepy, sluggish, and irritable. But what happens when sleepless nights accumulate into two, four, or even 11 nights?. Sleep, despite its ubiquity among humans and other animals, remains a mystery to scientists.

€œI’m fascinated by sleep because it occupies so much of our lives and yet it’s not fully understood,” says Brendan Lucey, associate professor of neurology and director of the Division of Sleep Medicine at Washington University in St. Louis, Missouri. Lucey says that while scientists don’t know exactly why sleep evolved, they theorize that its role in brain function, memory consolidation, and metabolism has led to its conservation across species. We spend about a third of our lives sleeping, and we know sleep is essential by looking at what happens when we go without it.

The loss in coordination and good judgment after just one sleepless night is comparable to that observed in a person with a blood alcohol level of .10 percent, above the legal limit for driving in most states. As sleepless nights accumulate, we exhibit increasingly stranger symptoms.24 hours. You may know that one night of lost sleep can cause fatigue, mental fog, tremors, irritability and reduced coordination. This slight deprivation also decreases blood flow and metabolism in the prefrontal cortex of the brain (the one responsible for higher reasoning like attention, problem solving, and decision making).

Our sense of smell is connected to this region, and one study found that after 24 hours of wakefulness people had trouble distinguishing between common smells like pizza, pineapple, and grass.48 hours. At two days without sleep, the body begins to experience physical symptoms of sleep loss. The immune system is impacted. Natural killer cells (responsible for fighting tumors and antabusees) decrease by 37 percent after just 48 hours of wakefulness, according to one study.

Visual hallucinations can also manifest — prolonged wakefulness causes images to form incorrectly on our retinas. These may be as benign as believing the room is larger than it is, or as frightening as the sudden appearance of an imaginary person or animal. 72 hours. At this point, your body will start finding ways to force you into unconsciousness.

Microsleeps are involuntary bursts of sleep lasting between 1 and 30 seconds. Often, you don’t know you’re having them. They can be dangerous if you happen to be driving, but you’ve probably experienced a more innocuous microsleep if you’ve ever nodded off during class or a meeting. Other forced sleep shows up on EEG readings.

Delta waves (those associated with deep sleep) have been detected in the brains of severely sleep-deprived, yet completely conscious, humans. 96 hours and beyond. You may slip into a state resembling psychosis at this stage. You could experience delusions, imagining that your neighbor is plotting your death, or becoming convinced you’re on a secret military mission.

Imagined sounds and sensations of touch creep into your consciousness. You may feel detached from yourself and others, a condition called depersonalization. You can no longer correctly interpret your reality. Does Sleep Deprivation Kill?.

Luckily, severely sleep-deprived people can fully recover from these symptoms with a good night’s rest. But what if sleep deprivation continues indefinitely?. Gardner perhaps demonstrated the upper limits of sleep deprivation that humans can withstand, but a rare genetic disorder called fatal familial insomnia (FFI) pushes past that threshold. Affecting less than one person per million each year, FFI is a prion disease characterized by a buildup of misfolded proteins in the brain.

Beginning with mild insomnia in middle age, the disease rapidly progresses to complete sleep loss followed by deterioration of brain regions responsible for essential functions like breathing and temperature regulation, resulting in coma and death.How to Get Better Sleep While mild sleep deprivation won’t kill you, it can have harmful effects on health. €œSleep is enrolled in a lot of systems” in the body, says Lucey. Insomnia, obstructive sleep apnea, and shift work are common causes of sleep deficiency and have been associated with a greater risk of heart disease, high blood pressure, type-2 diabetes, obesity, and Alzheimer’s disease. So, what can you do to get proper shuteye?.

Sara Benjamin, a clinical associate at the Johns Hopkins Center for Sleep, helps people overcome sleep problems. After identifying and treating physiological sleep disorders, Benjamin says good sleep boils down to routine. €œMost people do best with a set schedule,” she says. That means going to bed and waking up at the same time every day.

Also important, Benjamin says, is having a wind-down period before bed. A time when you stop doing productive things, put down your screens, and begin to relax. €œThere are so many things that we regiment in our lives, and you have to look at sleep as just as important as whatever else you're doing for your health.” In 1989, the Guinness Book of World Records discontinued the longest time without sleep category, citing health concerns for the participant. Though others have since broken his record, Gardner’s 264 hours without sleep stands as the last official entry.To scientists' surprise, more than 80 percent of Iowa's wild and captive white-tailed deer population tested positive for alcoholism (the antabuse that causes alcoholism treatment in humans) between late November 2020 and January of this year.

This revelation comes from a study posted to the pre-print server bioRxiv earlier this month. The percentage of positive samples increased throughout the course of the study, and one-third of the 283 samples ultimately tested positive.“Our studies show that while we were distracted with the antabuse in human populations during the winter months of 2020 and 2021, an outbreak of alcoholism was silently spreading amongst the deer herd quite unbeknownst to us,” says Suresh Kuchipudi, a co-author of the article and a clinical professor of veterinary and biomedical sciences at Pennsylvania State University. The authors note that the white-tailed deer, who is instantly recognizable to fans of Disney's Bambi, is the country's most popular wild deer species. Around 25 million call the U.S.

Home. The discovery that a significant portion of this population is also vulnerable to alcoholism now raises questions about the potential for an evolved version of the alcoholism to jump back into humans — which increases the likelihood that alcoholism treatment won't be wiped out completely and could instead become endemic, or a regular occurrence like the cold and flu.Caught in the HeadlightsThe idea to extract the lymph nodes, which are located in the head and neck, from hundreds of deer and test them for active didn’t come out of thin air. For one, these samples were already being collected by the Iowa Department of Natural Resources as part of its routine, statewide Chronic Wasting Disease surveillance program. But perhaps more importantly, previous studies had already identified the deer's elevated risk of contracting alcoholism.That's because the angiotensin-converting enzyme 2, or ACE2 receptor, of several animals bonds notably well with alcoholism, according to research published in the ​​Proceedings of the National Academy of Sciences in 2020.

The alcoholism is extremely adept at attacking the ACE2 receptor in humans, as well as in other primates. But the researchers were surprised to find that three species of deer, including white-tailed deer, were particularly vulnerable as well.“That's why people started to look at deer,” says Tony Goldberg, an epidemiology professor at the University of Wisconsin-Madison School of Veterinary Medicine who was not involved in the studies. €œIt wasn't because they were getting sick — deer weren't showing up for alcoholism treatment vaccinations. It was because the scientific community predicted that they would be susceptible.”This year, studies demonstrated that white-tailed deer could be inoculated with the antabuse and transmit it to one another, and that a large portion of the animal's U.S.

Population had already developed antibodies against alcoholism. But the presence of antibodies, though indicative of indirect exposure to the alcoholism, didn't actually prove that the deer were actively becoming infected.The key evidence. Recent genome sequencing conducted by Kuchipudi and other researchers at Penn State showed that alcoholism was present in white-tailed deer. This sequencing also indicated that related groups of antabuse variants found in the animals mapped closely to those circulating in human Iowans at that time, says Vivek Kapur, a professor of microbiology and infectious diseases at Pennsylvania State University and co-author of the most recent study.

The patterns of genetic variation they observed strongly suggest that multiple independent spillover events traveled from humans to the deer, he adds.“More people on public lands, limited food sources for the deer during the winter time, hunting-related disruption of deer movement and high burden among humans may all have contributed to the very high positivity rate we observed in the deer samples,” Kuchipudi says.In fact, the peak positivity rate among deer samples coincided very closely with both the Iowa hunting season and the peak rate among people in the state. Over 80 percent of deer samples were positive during late November through January. €œWe don't know [how because] it does seem like it's unusual for people to be breathing within six feet of a deer,” Goldberg says. €œThere may be a role for contamination of inanimate objects.

So if I have alcoholism treatment and I'm hunting deer or walking in the woods and I sneeze a big snot glob on a leaf, and a deer comes by a few hours later and sniffs it, that might do it.” He notes that researchers have speculated about other modes of transmission as well, such as through contaminated wastewater.The Reservoir That Won’t Run DryThe antabuse will likely stick around the new environment offered by deer, Goldberg says, and other experts share this view. €œConsidering how quickly it's been spreading among deer, the fact that they don't seem to be symptomatic, and the fact that the researchers found it in the lymph nodes of deer — which is usually indicative of a antabuse that has staying power — it's probably not going away anytime soon,” he says.Although the deer appear to be asymptomatic for now, researchers worry the alcoholism could continue to evolve as it passes from deer to deer and could eventually return to humans as something far more virulent and evasive of our natural (and vaccinated) immunity.Additionally, other wildlife that interact with deer are also at risk. €œSince deer are now identified as the second known free-living reservoir host for this antabuse, our studies highlight an urgent need to carry out comprehensive alcoholism surveillance of white-tailed deer together with other susceptible animals such as deer, mice [and] skunks,” Kapur says.In epidemiology, reservoirs are defined as populations or environments in which an infectious pathogen survives and thrives. We discovered that mink, for example, are susceptible to the antabuse when every mink in Denmark — a total surpassing 12 million from more than 200 farms — was culled over fears of alcoholism treatment late last year.

Wild mink are also widespread throughout much of North America, but so far only one has been found to be infected. Ultimately, the more animal reservoirs for the alcoholism, the more opportunities it has to evolve into something even more harmful. Within the next six months, Goldberg expects researchers to have a much clearer idea of where alcoholism has spread within the U.S. Deer population.Changing the Game PlanSo far, there’s no evidence that the antabuse can be transmitted from deer to humans, but it remains a concern.In fact, we have proof of infectious disease spreading from animals to humans.

Each year, a few unlucky people contract plague from infected prairie dogs, for example. But the National Wildlife Health Center successfully reduced the mortality from plague in four species of prairie dogs in seven states by distributing peanut butter-flavored, treatment-laden bait near burrows. The scientists incorporated a harmless dye that changed the color of the prairie dogs’ hair and whiskers under UV light, so they were able to determine that about 70 percent of the animals took the bait.Read More. Self-Spreading Animal treatments Could Combat Human antabusesSimilar efforts have attempted to combat rabies.

Earlier this year, for example, more than 500,000 baits containing the oral rabies treatment were dropped from aircraft in parts of North Carolina, with the intent of reducing the disease within raccoon populations. Although technologies for vaccinating wildlife exist, these endeavors are often difficult and expensive. So far, there are no such plans for white-tailed deer and the novel alcoholism.Because the transmission of alcoholism within deer populations depends on direct contact within dense herds, says Goldberg, one possible strategy for slowing the spread of the antabuse might be to thin those herds through changes to hunting practices. And for many hunters, deer season begins this month.

Recommendations from the U.S. Department of Agriculture so far include prohibiting contact between wildlife and domestic animals such as hunting dogs, avoiding any game that is found dead, and wearing gloves and a mask while processing it.While hunting practices may have contributed to the problem, they just might become part of the solution..
