The effectiveness of e-healthcare interventions for mental health of nurses: A PRISMA-compliant systematic review of randomized controlled trials.

BACKGROUND: Mental health problems, including burnout among nurses, are common and important. With the rapid development of information and communication technologies and the rise in use of smartphones, the use of e-mental health strategies is increasing in public and clinical settings, and initial clinical trials using this intervention have been conducted. This systematic review evaluated whether e-healthcare interventions improve burnout and other mental health aspects in nurses. METHODS: Six electronic databases including MEDLINE (via PubMed), EMBASE (via Elsevier), the Cochrane Library Central Register of Controlled Trials, the Cumulative Index of Nursing and Allied Health Literature, the Allied and Complementary Medicine Database, and PsycARTICLES were searched to collect relevant randomized controlled trials up to January 28, 2021, using e-healthcare interventions for mental health in nurses. The e-healthcare intervention was classified as web-based, smartphone-based, and real-time online interventions. The primary outcome was burnout in this population. Due to the heterogeneity of the interventions used in the included studies, quantitative synthesis was not performed, but included studies were analyzed qualitatively. Also, the details of e-healthcare for the mental health of nurses were analyzed. The methodological quality of included studies was assessed using Cochrane's Risk of Bias tool. RESULTS: Seven randomized controlled trials were included in this study. The 20-minute session of an online form of the emotional freedom technique was reported to significantly improve burnout severity compared to no intervention (P < .001). Other outcomes, such as career identity, quality of work life, workplace bullying, job stress, turnover intention, distress, anxiety, and resilience in nurses, were also reported to be improved by e-healthcare interventions. The methodological quality of the included studies was generally poor. CONCLUSIONS: In conclusion, there was some evidence that e-healthcare interventions may improve mental health outcomes, including burnout in nurses, compared with no intervention. However, due to the poor methodological quality and wide heterogeneity of the interventions and outcomes in the included studies, we were not able to reach sufficiently reliable conclusions. E-healthcare intervention for nurses in the new coronavirus disease era was discussed. High-quality clinical trials in this area should be conducted in the future.

The Effectiveness and Safety of Mind-Body Modalities for Mental Health of Nurses in Hospital Setting: A Systematic Review.

The mental health of nurses including burnout is an important issue. The purpose of this systematic review was to evaluate whether mind-body modalities improve burnout and other mental health aspects of nurses. A comprehensive search was conducted using six electronic databases. Randomized controlled trials using mind-body modalities on the mental health of nurses, up to January 2021, were included. The methodological quality of the included studies was assessed using the Cochrane Risk of Bias tool. Seventeen studies were included in the review. Data on mindfulness-based interventions (MBIs) and yoga were available for burnout, and there was no evidence that multimodal resilience programs including MBIs statistically significantly improved burnout levels compared to no intervention or active control groups. However, one study reported that yoga could significantly improve emotional exhaustion and depersonalization, which are subscales of burnout, compared to usual care. In addition, the effects of MBIs, relaxation, yoga, and music on various mental health outcomes and stress-related symptoms have been reported. In conclusion, there was some evidence that yoga was helpful for improvement in burnout of nurses. However, due to the heterogeneity of interventions and outcomes of the studies included, further high-quality clinical trials are needed on this topic in the future.

Identification of target genes regulated by the Drosophila histone methyltransferase Eggless reveals a role of Decapentaplegic in apoptotic signaling.

Epigenetic gene regulation is essential for developmental processes. Eggless (Egg), the Drosophila orthologue of the mammalian histone methyltransferase, SETDB1, is known to be involved in the survival and differentiation of germline stem cells and piRNA cluster transcription during Drosophila oogenesis; however the detailed mechanisms remain to be determined. Here, using high-throughput RNA sequencing, we investigated target genes regulated by Egg in an unbiased manner. We show that Egg plays diverse roles in particular piRNA pathway gene expression, some long non-coding RNA expression, apoptosis-related gene regulation, and Decapentaplegic (Dpp) signaling during Drosophila oogenesis. Furthermore, using genetic and cell biological approaches, we demonstrate that ectopic upregulation of dpp caused by loss of Egg in the germarium can trigger apoptotic cell death through activation of two pro-apoptotic genes, reaper and head involution defective. We propose a model in which Egg regulates germ cell differentiation and apoptosis through canonical and noncanonical Dpp pathways in Drosophila oogenesis.
