Practitioner Review: Unguided and guided self-help interventions for common mental health disorders in children and adolescents: a systematic review and meta-analysis

Mental health problems are common in children and adolescents, yet evidence-based treatments are hard to access. Self-help interventions can increase such access. The aim of this paper was to conduct a systematic review and meta-analysis of the use of guided and unguided self-help for children and young people with symptoms of common mental health disorders. In contrast to previous reviews of self-help in children, all types of self-help and multiple mental health disorders were investigated in order to increase power to investigate potential moderators of efficacy. Importantly, studies with control arms as well as those comparing against traditional face-to-face treatments were included. Fifty studies (n = 3396 participants in self-help/guided self-help conditions) met the inclusion criteria. Results demonstrated a moderate positive effect size for guided and unguided self-help interventions when compared against a control group (n = 44; g = 0.49; 95% CI: 0.37 to 0.61, p < .01) and a small but significant negative effect size when compared to other therapies (n = 15; g = −0.17; 95% CI: –0.27 to –0.07, p < .01). Few potential moderators had a significant effect on outcome. Most comparisons resulted in significant heterogeneity and therefore results are interpreted with caution.     

Insights into Genetic Characteristics and Virological Features of Endemic Avian Influenza A (H9N2) Viruses in Egypt from 2017–2021

From 2010 to 2013, genotype I avian influenza A(H9N2) viruses of the G1-lineage were isolated from several poultry species in Egypt. In 2014, novel reassortant H9N2 viruses were detected in pigeons designated as genotype II. To monitor the subsequent genetic evolution of Egyptian A(H9N2) viruses, we characterized the full genomes of 173 viruses isolated through active surveillance from 2017 to 2022. In addition, we compared the virological characteristics and pathogenicity of representative viruses. Phylogenetic analysis of the HA indicated that all studied sequences from 2017–2021 were grouped into G1-like H9N2 viruses previously detected in Egypt. Phylogenetic analysis indicated that the Egyptian A(H9N2) viruses had undergone further reassortment, inheriting four genes (PB2, PB1, PA, NS) from genotype II, with their remaining segments deriving from genotype I viruses (these viruses designated as genotype III). Studying the virological features of the two most dominant genotypes (I and III) of Egyptian H9N2 viruses in vitro and in vivo indicated that both replicated well in mammalian cells, but did not show any clinical signs in chickens, ducks, and mice. Monitoring avian influenza viruses through surveillance programs and understanding the genetic and antigenic characteristics of circulating H9N2 viruses are essential for risk assessment and influenza pandemic preparedness.     

A comparison of the effectiveness of a game informed online learning activity and face to face teaching in increasing knowledge about managing aggression in health settings

The present study compared the impact of face to face teaching with a short online game informed learning activity on health participants’ knowledge about, and confidence in, managing aggressive situations. Both forms of teaching resulted in a significant increase in participants’ knowledge and confidence. Face to face training led to significantly greater increases in knowledge but was equivalent in terms of confidence. Both forms of teaching were rated positively, but face to face teaching received significantly higher ratings than the online activity. The study suggests that short online game informed learning activities may offer an effective alternative for health professional training where face to face training is not possible. Further research is needed on the longer term impact of both types of training on practice.     

Serum Immune Complexes and Disease

Summary: The solid phase Clq radioimmunoassay was used to detect immune complexes in sera from patients with systemic lupus erythematosus (14/25), rheumatoid arthritis (4/5), vasculitis (5/15), infective endocarditis (2/2), acute rheumatic fever (2/3), pre-eclamptic toxaemia (0/14), lung cancer (3/7), glomerulonephritis (26/98) and renal transplant patients (0/5). The best correlation with disease activity was seen in systemic lupus erythematosus and infective endocarditis where serial immune complex determinations were clearly of value in monitoring therapy. The findings in primary glomerulonephritis indicate only a limited usefulness of the assay in that serum immune complexes were detected in a minority (22/73) of patients with glomerular immune deposits. In particular the data do not support a role for Clq fixing immune complexes in the pathogenesis of membranous glomerulonephritis or in pre-eclamptic toxaemia.     

An initial report on a double-blind trial comparing small and large doses of gold in the treatment of rheumatoid disease.

A double-blind clinical trial on 60 patients with rheumatoid disease comparing 10 mg sodium aurothiomalate weekly to 50 mg weekly is continuing. An initial report on thirty of these patients, who had completed a year of treatment, shows no statistically significant difference in the response between the two groups. No conclusions can be drawn about toxic reactions in this number of patients having received treatment for only one year.
