Risk and protective factors associated with adolescent depression in Singapore: a systematic review.

Introduction: Adolescent depression is prevalent, and teen suicide rates are on the rise locally. A systemic review to understand associated risk and protective factors is important to strengthen measures for the prevention and early detection of adolescent depression and suicide in Singapore. This systematic review aims to identify the factors associated with adolescent depression in Singapore. Methods: A systematic search on the following databases was performed on 21 May 2020: PubMed, EMBASE and PsycINFO. Full texts were reviewed for eligibility, and the included studies were appraised for quality using the Newcastle Ottawa Scale. Narrative synthesis of the finalised articles was performed through thematic analysis. Results: In total, eight studies were included in this review. The four factors associated with adolescent depression identified were: (1) sociodemographic factors (gender, ethnicity); (2) psychological factors, including childhood maltreatment exposure and psychological constructs (hope, optimism); (3) coexisting chronic medical conditions (asthma); and (4) lifestyle factors (sleep inadequacy, excessive internet use and pathological gaming). Conclusion: The identified factors were largely similar to those reported in the global literature, except for sleep inadequacy along with conspicuously absent factors such as academic stress and strict parenting, which should prompt further research in these areas. Further research should focus on current and prospective interventions to improve mental health literacy, targeting sleep duration, internet use and gaming, and mitigating the risk of depression in patients with chronic disease in the primary care and community setting.

A Systematic Review of Youth and Teen Mental Health First Aid: Improving Adolescent Mental Health.

PURPOSE: Adolescent mental illness often goes undetected. Youth and teen Mental Health First Aid (MHFA) are variations of adult MHFA that aims to help adults and adolescents recognize the signs and provide help where appropriate. We conducted a systematic review to summarize the current evidence for youth and teen MHFA, providing direction for future training and research. METHODS: A systematic search was performed on September 12, 2020 on PubMed, Embase, PsycINFO, ERIC, and Cochrane using keywords related to teen or youth MHFA, adolescents, and mental health. A narrative synthesis was then carried out. RESULTS: Of the 695 articles identified, 14 studies were included. All studies were from the U.S. and Australia. All studies demonstrated significant improvements in knowledge, recognition, stigmatizing attitudes, confidence, helping intentions, and helping behavior in both adult and youth participants. Improvement in knowledge and confidence was most reported, and improvement in helping behavior was the least reported. There is encouraging evidence of long-term benefits after the training. CONCLUSIONS: More studies need to be conducted in non-Western countries, high-risk populations, and different professional settings. Future interventions could also consider different modes of learning, longer-term follow-up, and the measurement of outcomes that evaluate the quality of helping behavior.

Biodegradable Block Copolyelectrolyte Hydrogels for Tunable Release of Therapeutics and Topical Antimicrobial Skin Treatment.

Biodegradable polycarbonate-based ABA triblock copolyelectrolytes were synthesized and formulated into physically cross-linked hydrogels. These biocompatible, cationically, and anionically charged hydrogel materials exhibited pronounced shear-thinning behavior, making them useful for a variety of biomedical applications. For example, we investigated the antimicrobial activity of positively charged thiouronium functionalized hydrogels by microbial growth inhibition assays against several clinically relevant Gram-negative and Gram-positive bacteria. It is noteworthy that these hydrogels exhibited broad spectrum killing efficiencies approaching 100%, thereby rendering these thixotropic materials attractive for treatment of skin and other surface bound infections. Finally, cationic trimethylammonium containing hydrogels and anionic carboxylic acid functionalized hydrogels were utilized to sustain the release of negatively charged (diclofenac) and positively charged (vancomycin) therapeutics, respectively. Collectively, the present work introduces a simple method for formulating charged hydrogel materials that are capable of interacting with various analytes of interest through noncovalent interactions.
