Schizophrenia and bipolar disorder are common, severe, and disabling psychotic disorders, which are difficult to research. We argue that the genetically determined neurodevelopmental disorder Prader-Willi syndrome (PWS), which is associated with a high risk of affective psychotic illness, can provide a window into genetic mechanisms and associated neural pathways. People with PWS can all show non-psychotic psychopathology and problem behaviours, but the prevalence of psychotic illness differs markedly by genetic subtype; people with PWS due to chromosome 15 maternal uniparental disomy have higher prevalence of psychotic illness compared with patients with PWS due to 15q11-13 deletions of paternal origin...

Sexual dysfunction often accompanies severe psychiatric illness and can be due to both the mental disorder itself and the use of psychotropic treatments. Many sexual symptoms resolve as the mental state improves, but treatment-related sexual adverse events tend to persist over time, and are unfortunately under-recognized by clinicians and scarcely investigated in clinical trials. Treatment-emergent sexual dysfunction adversely affects quality of life and may contribute to reduce treatment adherence. There are important differences between the various compounds in the incidence of adverse sexual effects, associated with differences in mechanisms of action...

In the mammalian retina, horizontal cells receive glutamatergic inputs from many rod and cone photoreceptors and return feedback signals to them, thereby changing photoreceptor glutamate release in a light-dependent manner. Horizontal cells also provide feedforward signals to bipolar cells. It is unclear, however, how horizontal cell signals also affect the temporal, spatial and contrast tuning in retinal output neurons, the ganglion cells. To study this, we generated a genetically modified mouse line in which we eliminated the light dependency of feedback by deleting glutamate receptors from mouse horizontal cells...

BACKGROUND: Ratings of particular temperament-types with the TEMPS-A autoquestionnaire have been associated with suicidal risk, and combinations of such ratings may enhance the association. However, the predictive value of scores for individual temperaments and combinations remains to be quantified. METHOD: We evaluated associations of TEMPS-A ratings for anxious (anx), cyclothymic (cyc), dysthymic (dys), hyperthymic (hyp) and irritable (irr) temperaments, with a history of suicidal acts or reported suicidal ideation in 882 patients with bipolar (BD; n = 509), major depressive (MDD; n = 268) or anxiety (ANX; n = 105) disorders...

OBJECTIVE: A paucity of corroborative psychological and psychiatric evidence may be inhibiting detection of drug intoxication suicides in the United States. We evaluated the relative importance of suicide notes and psychiatric history in the classification of suicide by drug intoxication versus firearm (gunshot wound) plus hanging/suffocation-the other two major, but overtly violent methods. METHODS: This observational multilevel (individual/county), multivariable study employed a generalized linear mixed model (GLMM) to analyze pooled suicides and undetermined intent deaths, as possible suicides, among the population aged 15 years and older in the 17 states participating in the National Violent Death Reporting System throughout 2011-2013...

BACKGROUND: Despite ongoing advances in the treatment of mood disorders, a substantial proportion of people diagnosed with major depression or bipolar disorder remain symptomatic over time. Yoga, which has been shown to reduce stress and depressive symptoms, as well as to improve overall quality of life, shows promise as an adjunctive treatment. However, dissemination of yoga for clinical populations remains challenging. The purpose of this pilot study was to test the feasibility and acceptability of an online yoga intervention for individuals with mood disorders...

Background Many psychiatric disorders including schizophrenia, bipolar disorder and major depression convey an excess burden of cardiovascular morbidity and mortality. The medications used to treat these conditions may further adversely affect cardiovascular risk and exacerbate health disparities for vulnerable populations. There is a clinical need to appreciate the cardiometabolic adverse effects of psychotropic medications. Methods This paper reviews the most relevant cardiometabolic effects of psychotropic medications, organized around the components of metabolic syndrome...

Few replicable genetic associations for Major Depressive Disorder (MDD) have been identified. Recent studies of MDD have identified common risk variants by using a broader phenotype definition in very large samples, or by reducing phenotypic and ancestral heterogeneity. We sought to ascertain whether it is more informative to maximize the sample size using data from all available cases and controls, or to use a sex or recurrent stratified subset of affected individuals. To test this, we compared heritability estimates, genetic correlation with other traits, variance explained by MDD polygenic score, and variants identified by genome-wide meta-analysis for broad and narrow MDD classifications in two large British cohorts - Generation Scotland and UK Biobank...

Timing walk error in pulsed time-of-flight based laser range finding was studied using two different types of laser diode drivers. The study compares avalanche bipolar junction transistor (BJT) and metal-oxide-semiconductor field-effect transistor switch based laser pulse drivers, both producing 1.35 ns current pulse length (full width at half maximum), and investigates how the slowly rising part of the current pulse of the avalanche BJT based driver affects the leading edge timing walk. The walk error was measured to be very similar with both drivers within an input signal dynamic range of 1:10 000 (receiver bandwidth of 700 MHz) but increased rapidly with the avalanche BJT based driver at higher values of dynamic range...

OBJECTIVE: Circadian rhythm dysfunction has been considered to be common in bipolar disorder (BD) and plays an important role in mood dysregulation in this disorder. However, no study has investigated whether circadian rhythm dysfunction would affect the clinical course of BD. The aim of this study was to test the hypothesis that circadian rhythm dysfunction could be a predictor of relapse in euthymic BD patients. METHODS: One hundred four euthymic outpatients with BD diagnosed according to the criteria of the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition (DSM-5), participated in this prospective follow-up study from August 2014 to April 2015...

Obsessive-compulsive disorder (OCD) is a chronic illness with waxing and waning course. OCD is not uncommonly found to be comorbid with bipolar affective disorder (BPAD). The course and prognosis of OCD have distinctive features in such cases. Only rarely symptoms of OCD emerge during mania in such individuals. We hereby report a very unusual case of OCD comorbid with BPAD in which obsession and compulsion symptoms occurred only during manic episodes with complete remission during periods between manic episodes (including during depressive episodes)...
