RESUMO

The European Union member states received about 385,000 asylum applications from children and adolescents below 18 years in 2015, and 398,000 in 2016. The latest political crises and war have led to an upsurge in refugee movements into European countries, giving rise to a re-evaluation of the epidemiology of psychiatric disorders and mental health problems among young refugees and asylum seekers. We systematically searched five electronic databases and reference lists of pertinent review articles. We then screened the results of forward citation tracking of key articles for relevant studies in the field for the period from January 1990 to October 2017. We dually reviewed citations and assessed risk of bias. We reported the results narratively, as meta-analyses were impeded due to high heterogeneity. We included 47 studies covered in 53 articles. Overall, the point prevalence of the investigated psychiatric disorders and mental health problems varied widely among studies (presenting interquartile ranges): for posttraumatic stress disorder between 19.0 and 52.7%, for depression between 10.3 and 32.8%, for anxiety disorders between 8.7 and 31.6%, and for emotional and behavioural problems between 19.8 and 35.0%. The highly heterogeneous evidence base could be improved by international, methodologically comparable studies with sufficiently large sample sizes drawn randomly among specific refugee populations. The prevalence estimates suggest, nevertheless, that specialized mental health care services for the most vulnerable refugee and asylum-seeking populations are needed.

RESUMO

We rated the body of evidence for 219 health-related questions that had been covered by 990 media articles in Austrian print and online media. In 59.5 % of these articles, the evidence for medical facts is reported in a highly distorted (exaggerated or understated) manner; only 10.8 % adequately reflect the actual strength of evidence. While 61.3% of the articles imply that the reported effects are based on the highest level of evidence, it really only applies to 2.6% of the articles. Compared to quality media, tabloid media report in a more distorted way. However, this is mainly due to a different subject coverage, since the degree of distorted reporting does not significantly differ for subjects covered by both tabloid and quality media. Online media do not report in a more distorted way than print media, with the exception of the newspaper "Der Standard". A clear difference can be seen in the reporting on different subjects. Articles on medications regulated by governmental authorities or interventions which only physicians are allowed to perform were significantly less distorted than articles on nutritional supplements or interventions that may be provided by non-physician staff. Reports on cosmetic or weight loss interventions were most distorted.

RESUMO

The multifunctional scaffolding protein gephyrin is a key player in the formation of the postsynaptic scaffold at inhibitory synapses, clustering both inhibitory glycine receptors (GlyRs) and selected GABA(A) receptor (GABA(A)R) subtypes. We report a direct interaction between the GABA(A)R α3 subunit and gephyrin, mapping reciprocal binding sites using mutagenesis, overlay, and yeast two-hybrid assays. This analysis reveals that critical determinants of this interaction are located in the motif FNIVGTTYPI in the GABA(A)R α3 M3-M4 domain and the motif SMDKAFITVL at the N terminus of the gephyrin E domain. GABA(A)R α3 gephyrin binding-site mutants were unable to co-localize with endogenous gephyrin in transfected hippocampal neurons, despite being able to traffic to the cell membrane and form functional benzodiazepine-responsive GABA(A)Rs in recombinant systems. Interestingly, motifs responsible for interactions with GABA(A)R α2, GABA(A)R α3, and collybistin on gephyrin overlap. Curiously, two key residues (Asp-327 and Phe-330) in the GABA(A)R α2 and α3 binding sites on gephyrin also contribute to GlyR ß subunit-E domain interactions. However, isothermal titration calorimetry reveals a 27-fold difference in the interaction strength between GABA(A)R α3 and GlyR ß subunits with gephyrin with dissociation constants of 5.3 µm and 0.2 µm, respectively. Taken together, these observations suggest that clustering of GABA(A)R α2, α3, and GlyRs by gephyrin is mediated by distinct mechanisms at mixed glycinergic/GABAergic synapses.
