This study examined the effectiveness of an Internet-based trauma recovery intervention for Korean nurses.\u0000Methods: This randomized controlled trial was conducted with 112 nurses aged 23–40 years who were randomly assigned to the intervention (n = 56) or control group (n = 56) from May 7 to December 20, 2020. Nurses in the intervention group attended eight sessions, and the same intervention was administered to the control group. Repeated measures were collected at pre-test, post-test 1 (immediately after the intervention), and post-test 2 (four weeks after the intervention). A total of 102 nurses (intervention group: n = 49; control group: n = 53) were completed because 10 nurses dropped out before the first session. Data were analyzed using the chi-square test, Fisher’s exact test, t-test, Mann-Whitney U-test, and repeated measures ANOVA (intention-to-treat and per protocol).\u0000Results: There were significant changes in functional health, resilience, post-traumatic stress, depressive symptoms, state anxiety, and trait anxiety over time and in the group-by-time interactions (intention-to-treat and per protocol). There was a significant difference in social support in the group-by-time interactions, but there were no significant changes between the two groups or over time (intention-to-treat and per protocol).\u0000Conclusion: The Internet-based trauma recovery nursing intervention is effective in clinical and community settings for nurses who cannot participate in fixed-schedule programs due to shift work. This study’s findings are relevant for implementing Internet-based trauma recovery programs for nurses and the general population, including survivors and relatives of patients who suffered from COVID-19. This program will also be very useful for people in other high-stress situations. Nurse leaders should consider different populations and situations when offering effective coping strategies suitable for changing environments.\u0000Clinical trial registration number: NCT04989582","PeriodicalId":72654,"journal":{"name":"Complex psychiatry","volume":"13 15","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-07-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141816350","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To investigate biological underpinnings of heterogeneity in MD, the associations between depression, stratified by sex and including perinatal depression (PND), and blood biomarkers, using UK Biobank (UKB) data, were evaluated, and extended to include the association of depression with biomarker polygenic scores (PGS), generated as proxy for each biomarker. \u0000Method\u0000Using female (N=39,761) and male (N=38,821) UKB participants, lifetime major depression (MD) and PND, were tested for association with 28 blood biomarkers. A GWAS was conducted for each biomarker and genetic correlations with depression subgroups were estimated. Using independent data from the Australian Genetics of Depression Study, PGS were constructed for each biomarker, and tested for association with depression status (n [female cases/controls]=9,006/6,442; n [male cases/controls]=3,106/6,222).

The pandemic had a profoundly negative impact on the mental health of first-year students because they were not prepared to face academic and social stresses. The purpose of this study was to investigate the effect of the COVID-19 pandemic on depressive symptoms, eating behaviors and stress coping ability among first-year university students. Methods: A total of 8,424 first-year students, 2,043 males and 1,636 females who entered university in Japan in 2021-2022 (during the pandemic) and 2,912 males and 1,833 females who entered university in Japan in 2018-2019 (before the pandemic), participated. We investigated the differences in depressive symptoms (using BDI-II), eating behaviors (using EAT-26 and BITE) and stress coping (using CISS, which has three subscales) between first-year students before and during the pandemic. We divided the students into three categories (clinical, subthreshold, and nonsymptomatic) according to depressive symptoms and eating behaviors based on BDI-ll and EAT-26 scores and compared the frequencies of the three categories at two time points. Results: First-year students during the pandemic showed a higher percentage of depressive symptoms, including clinical and subthreshold levels, than first-year students before the pandemic but did not show disordered eating behaviors. Additionally, the CISS-T score was significantly lower for students with depressive symptoms, including clinical and subthreshold levels, during the pandemic than before the pandemic in females. Conclusions: This study suggests that it may be important to provide first-year university students with more information about depressive symptom awareness, including clinical and subthreshold levels, and to provide appropriate stress coping from many angles and early support in pandemic conditions.","PeriodicalId":72654,"journal":{"name":"Complex psychiatry","volume":"35 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"138979337","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, post-GWAS analyses are needed to extend the statistical inference to biologically relevant entities, e.g., genes, proteins, and pathways. To achieve this goal, researchers developed methods that incorporate biologically relevant intermediate molecular phenotypes, such as gene expression and protein abundance, which are posited to mediate the variant-trait association. Transcriptome-wide association study (TWAS) and proteome-wide association study (PWAS) are commonly used methods to test the association between these molecular mediators and the trait.</p><p><strong>Summary: </strong>In this review, we discuss the most recent developments in TWAS and PWAS.
