The genetic basis of mood disorders can, theoretically, provide diagnostic information in scenarios of clinical uncertainty. Therefore, we examined the available body of knowledge on the association between polygenic risk scores for bipolar disorder (BP-PRSs) and pediatric bipolar spectrum and related disorders. We performed a literature search through PubMed in March of 2020. The following variables were extracted from relevant studies population age, study sample size, source of polygenic risk scores, source of data, the primary goal of the study, the assessments used during the course of the study, and the main findings/outcomes of each study. BP-PRSs were associated with deficits in executive functioning and the diagnosis of attention deficit/hyperactivity disorder (ADHD). Three studies included in our analysis directly compared major depressive disorder (MDD)-PRSs to BP-PRSs in youth. Results showed that MDD-PRSs, and not BP-PRSs, were associated with ADHD symptoms, internalizing problems, and social problems. ADHD-PRSs were associated with conduct problems, depressive symptomatology, and externalizing disorders symptoms. Findings revealed that ADHD-PRSs were more clearly associated with emotional reactivity, emotional dysregulation, and irritability-frequent correlates of pediatric BP disorder. These findings suggest that ADHD-PRSs may have an important contribution to the development of mood related problems in youth.Previous studies have suggested the involvement of Nogo-A/RTN4 in the pathogenesis of schizophrenia. We investigated an association between the promoter haplotypes of RTN4 comprised of rs1348528-rs1822618-rs2241958 and schizophrenia. A significant association between the rare TGA haplotype and schizophrenia was shown (p less then 0.0001). Additionally, the promoter activity was profoundly decreased by the TGA haplotype. These results suggested that the TGA haplotype of RTN4 may contribute to the susceptibility of schizophrenia.The COVID-19 outbreak has been associated with significant occupational stressors and challenges for healthcare workers (HCWs) including the risk of exposure to SARS-CoV-2. Many reports from all over the world have already found that HCWs have significant levels of self-reported anxiety, depression and even symptoms of post-traumatic stress disorder. Therefore, supporting mental health of HCWs is a crucial part of the public health response to the COVID-19 pandemic. The aim of the present review is to ascertain the interventions put in place worldwide in reducing stress in HCWs during the COVID-19 outbreak. We evidenced how only few countries have published specific psychological support intervention protocols for HCWs. All programs were developed in university associated hospitals and highlighted the importance of multidisciplinary collaboration. All of them had as their purpose to manage the psychosocial challenges to HCW's during the pandemic in order to prevent mental health problems.Whether one program offers distinct benefit compared to the others cannot be known given the heterogeneity of the protocols and the lack of a rigorous protocol and clinical outcomes. Further research is crucial to find out the best ways to support the resilience and mental well-being of HCWs. This study aims to elucidate the association paths between subjective sleep quality and the learning and memory ability of drug-free patients with schizophrenia. 150 patients with schizophrenia were recruited. Information on clinical and socio-demographic was obtained, and a neurocognitive battery was administered. The Pittsburgh Sleep Quality Index (PSQI) was used to assess the quality of subjective sleep. The Verbal Learning Test and the Visual Learning Test that were taken from the MATRICS Consensus Cognitive Battery were used to assess the patient's ability to learn and recall. Structural equation modelling (SEM) was performed to examine the relationship between subjective sleep quality and learning and memory ability .The model was further modified and fitted. There were significant negative correlations between learning and memory variables and the PSQI scores or the PANSS scores. Significant direct effect of PSQI on Verbal Learning and Visual Learning, and significant indirect effect of PSQI on Verbal Learning and Visual Learning through psychotic symptoms were found in the most plausible SEM model that explains the data. Subjective sleep quality has a direct impact on the ability to learn and memory, and indirectly affects the ability to learn and memory through psychotic symptoms in drug-free patients with schizophrenia. Sleep quality could be an intervention target for improving cognitive function in patients with schizophrenia.

So far, smaller studies on the relationship between mental disorders and blood types yielded contradicting results. In this study we analyzed the association between ABO blood types and lifetime major depressive disorder (MDD). We performed a pooled analysis with data from 26 cohorts that are part of the MDD working group of the Psychiatric Genomics Consortium (PGC). The dataset included 37,208 individuals of largely European ancestry of which 41.6% were diagnosed with lifetime MDD. ABO blood types were identified using three single nucleotide polymorphisms in the ABO gene rs505922, rs8176746 and rs8176747. Regression analyses were performed to assess associations between the individual ABO blood types and MDD diagnosis as well as putative interaction effects with sex. The models were adjusted for sex, cohort and the first ten genetic principal components. The percentage of blood type A was slightly lower in cases than controls while blood type O was more prominent in cases. However, these differences were not statistically significant. Our analyses found no evidence of an association between ABO blood types and major depressive disorder.
