Summary: Schizophrenia, bipolar disorder, and major depressive disorder are the most common psychiatric disorders. Diagnosing these disorders is difficult due to overlaps in genetic epidemiology and molecular genetics. This study used transcriptomic data to identify key genes and construct a classification model for differentiating these disorders. The model showed potential for improving the diagnoses of these psychiatric disorders.

Summary: Research suggests that both genetic and environmental risk factors are involved in the development of schizophrenia and major depressive disorder. The study found that gene-environment correlation gets stronger over time and the majority of this correlation remains stable across different development periods.

Summary: This study shows differences in genetic association between bipolar I disorder (BD-I) and bipolar II disorder (BD-II) with schizophrenia (SCZ) and major depressive disorder (MDD). The study finds that BD-II is more polygenic compared to BD-I, SCZ, and MDD, and there is substantial polygenic overlap between BD-I and SCZ, as well as between BD-I and MDD. The study also identifies specific shared genetic loci between BD subtypes and SCZ or MDD.

Summary: Near-infrared spectroscopy (NIRS) can be used to differentiate major depressive disorder (MDD), bipolar disorder (BPD), and schizophrenia (SZ) at the individual level by analyzing the spatiotemporal characteristics of hemodynamic responses. This can provide diagnostic support in clinical settings.

Summary: Schizophrenia and affective disorder are complex mental disorders with high heritability. Rare variants contribute to the genetic liability of these two disorders. Whole genome sequencing analysis identified multiple rare inherited variants in two families, providing evidence that these variants may contribute to the heritability of psychiatric disorders.

Summary: Pharmacotherapy is the most common treatment for SCZ, BD, and MDD, but pharmacogenetic studies have limited clinical utility. DNAm, an epigenetic modification, has been proposed to be involved in the pathogenesis and drug treatment of these disorders. BDNF DNAm shows promise as a predictor of antidepressant treatment response for MDD, while more pharmacoepigenetic studies are needed for a variety of diseases. Future research should utilize system-wide analysis and strict analytical procedures.

Summary: The study found a potential relationship between the rs144643855 variation in the NEUROG3 gene and altered frontal brain activity in MDD patients. Specific brain regions were significantly associated with clinical manifestations, suggesting a possible role for NEUROG3 in the neuropathophysiology of MDD.

Summary: The study investigated brain phenotyping in patients with schizophrenia and major depressive disorder using EEG. Patients showed deficiencies in N1 and P3 components in the sum of amplitudes and cortical sources, indicating attentional dysfunction. LDA and SVM classifiers in the AP300 are useful for distinguishing patients with SZ and HCs and/or MDD and HCs.

Summary: In this study, the association between positive emotion expression in children's writing at age 11 and well-being outcomes at age 50 was investigated. The study found that positive emotion expression at age 11 was related to greater optimism, life satisfaction, meaning in life, and social well-being, but not positive emotions or physical health.

Summary: Elevated rates of mental health difficulties are often seen in conflict-affected and displaced populations. This study aimed to review challenges and share lessons learned from administering and supervising a structured clinical interview. The findings suggest that cultural and contextual sensitivity, addressing practical barriers, and considering interconnected formulations are essential in informing prevalence rates, treatment plans, and public health strategies.

Summary: This study investigated the relationship between war exposure, current living conditions, hair cortisol concentrations (HCC), and post-traumatic stress disorder (PTSD) symptoms in a cohort of Syrian refugee children and adolescents. The findings suggest that HCC is weakly associated with the number of war-related events experienced, particularly for those who were at least 12 years old at the time of war exposure. However, HCC decreases with time since leaving Syria and is associated with PTSD symptoms but not with the quality of current living conditions.

Summary: According to various theories, individuals vary in their sensitivity to environmental influences, with some being more susceptible to both positive and negative contextual conditions. This sensitivity has a genetic basis but is also influenced by environmental factors. This article proposes that prenatal experiences contribute to the development of environmental sensitivity and provides empirical evidence to support this hypothesis. The study explores the biological mechanisms involved in the pathway from prenatal stress exposure to postnatal environmental sensitivity and discusses factors that may moderate the effects of prenatal programming. Additionally, the article highlights unknowns in prenatal programming and their practical implications.

Summary: This study aims to develop a consensus-based research agenda for mental health and psychosocial support (MHPSS) interventions in humanitarian settings for 2021-30. Through qualitative studies, consultations, and expert panel evaluations, a final list of 20 research questions was selected and rated, with a focus on applied research and systems-oriented implementation. Answering these questions requires improved partnerships and equity in funding for MHPSS research in low-income and middle-income countries.

Summary: This study presents an integrated theoretical perspective on Environmental Sensitivity and provides new empirical evidence. Results from three studies show that sensitivity can be measured reliably and validly with the 12-item Highly Sensitive Person scale (HSP-12). People scoring high on the HSP-12 are more sensitive to both adverse and positive experiences. The findings confirm the theoretical proposition that people differ in their sensitivity to environmental influences, and propose future directions for research.

Summary: The instability hypothesis suggests that family structure transitions can lead to negative child outcomes through stress. However, this study found that in many cases, family structure transitions were not associated with stress or negative child outcomes. The study aimed to test the instability hypothesis and examine the specific circumstances under which family structure transitions lead to stress and worsened child physical health. The findings suggest the need for further exploration of the instability hypothesis to understand the specific conditions that influence the impact of family structure transitions on child outcomes.

Summary: This study aimed to investigate the distinctiveness of Environmental Sensitivity (ES) captured by the Highly Sensitive Person 12-item scale (HSP-12) from traditional personality traits and its independent contribution to psychological adjustment, as well as the influence of rearing environment. The study also explored the psychometric properties of HSP-12 and its invariance across countries (UK and Italy) and samples (university and general population). The results provided evidence that ES can be reliably assessed using HSP-12 across different countries and groups, and it is distinguishable from established personality traits. ES was found to be associated with lower well-being and negative affect beyond personality, and a caring environment played a buffering role.
