BACKGROUND: Many studies have found an association between mood-disorder-related traits and endometriosis and adenomyosis. However, the cause-effect relationship remains unclear. AIMS: We conducted Mendelian randomisation analyses to evaluate any causal relationship between mood disorders and endometriosis as well as different sites of endometriosis. METHOD: Summary-level statistics for mood-disorder-related traits and endometriosis (8288 cases, 68 969 controls) in European populations were derived from large-scale data-sets of genome-wide association studies...

What humans look at strongly determines what they see. We show that individual differences in the tendency to look at positive stimuli are stable across time and across contents, establishing gaze positivity preference as a perceptual trait that determines the amount of positively valence stimuli individuals select for visual processing. Furthermore, we show that patients with major depressive disorder exhibit consistently low positivity preference before treatment. In a subset of patients, we also assessed the positivity preference after two months of treatment in which positivity gaze preference increased to levels similar to healthy individuals...

BACKGROUND: Major Depressive Disorder (MDD) is a prevalent and debilitating condition, necessitating novel therapeutic strategies due to the limited efficacy and adverse effects of current treatments. We explored how galanin receptor 2 (GALR2) and Neuropeptide Y1 Receptor (NPYY1R) agonists, working together, can boost brain cell growth and increase antidepressant-like effects in rats. This suggests new ways to treat Major Depressive Disorder (MDD). RESEARCH DESIGN AND METHODS: In a controlled laboratory setting, adult naive Sprague-Dawley rats were administered directly into the brain's ventricles, a method known as intracerebroventricular (ICV) administration, with GALR2 agonist (M1145), NPYY1R agonist, both, or in combination with a GALR2 antagonist (M871)...

BACKGROUND: Substantial observational evidence suggests an association between neuropsychiatric conditions and Venous Thromboembolism (VTE). However, the causal relationship between these two conditions requires further investigation. Therefore, we employed a two-sample Mendelian Randomization (MR) approach to assess bidirectional causal effects between four neuropsychiatric conditions and VTE, Deep Vein Thrombosis (DVT), and Pulmonary Embolism (PE). METHODS: Genetic variants associated with four neuropsychiatric conditions, including Schizophrenia (SCH), Major Depressive Disorder (MDD), Bipolar Disorder (BD), and Epilepsy, as well as VTE, DVT, and PE were selected...

BACKGROUND: Depression is a highly prevalent and disabling mental health condition among adolescents. The epidemiology of depression in adolescents has been changing over time, reflecting changes in risk factors as well as disease concepts and diagnosis. However, few studies have characterized the longitudinal epidemiology of depression in adolescents. Understanding trends of disease burden provides key insights to improve resource allocation and design targeted interventions for this vulnerable population...

This study examined predictors of, and associations between, self-concept, demographic variables, and clinical measures in fifty-eight children and adolescents with Persistent Tic Disorder (PTD; 44 males, Mage  = 11.9 years, SD = 2.74). Participants completed measures that assessed self-concept, tic severity, tic-related impairment, and comorbid psychological symptoms. Results showed that generalized anxiety disorder, major depressive disorder, persistent depressive disorder, total tic severity, number and complexity of tics, and total and social tic-related impairment were associated with self-concept...

INTRODUCTION: Suicide is a serious global public health issue, and a history of attempted suicide is the most critical indicator of suicide risk. There are limited studies on the effectiveness of psychotherapy in individuals who have attempted suicide, and other outcome measures related to suicide risk in suicide attempts have not been explored. AIM/QUESTION: This study aimed to systematically review and perform a meta-analysis of the effectiveness of psychotherapy on individuals who have attempted suicide...

The 5-HT2A receptor is a molecular target of high pharmacological importance. Ligands of this protein, particularly atypical antipsychotics, are useful in the treatment of numerous mental disorders, including schizophrenia and major depressive disorder. Structure-based virtual screening using a 5-HT2A receptor complex was performed to identify novel ligands for the 5-HT2A receptor, serving as potential antidepressants. From the Enamine screening library, containing over 4 million compounds, 48 molecules were selected for subsequent experimental validation...

BACKGROUND: In West Africa, healers greatly outnumber trained mental health professionals. People with serious mental illness (SMI) are often seen by healers in "prayer camps" where they may also experience human rights abuses. We developed "M&M," an 8-week-long dual-pronged intervention involving (1) a smartphone-delivered toolkit designed to expose healers to brief psychosocial interventions and encourage them to preserve human rights (M-Healer app), and (2) a visiting nurse who provides medications to their patients (Mobile Nurse)...

The primary outcome was the prevalence of EB, self-reported using a validated screening question...

Stress has been considered as a major risk factor for depressive disorders, triggering depression onset via inducing persistent dysfunctions in specialized brain regions and neural circuits. Among various regions across the brain, the lateral habenula (LHb) serves as a critical hub for processing aversive information during the dynamic process of stress accumulation, thus having been implicated in the pathogenesis of depression. LHb neurons integrate aversive valence conveyed by distinct upstream inputs, many of which selectively innervate the medial part (LHbM) or lateral part (LHbL) of LHb...
