- Using the ImmunoChip custom genotyping array, we analyzed 14,498 subjects with multiple sclerosis and 24,091 healthy controls for 161,311 autosomal variants and identified 135 potentially associated regions (P < 1.0 × 10(-4)). In a replication phase, we combined these data with previous genome-wide association study (GWAS) data from an independent 14,802 subjects with multiple sclerosis and 26,703 healthy controls. In these 80,094 individuals of European ancestry, we identified 48 new susceptibility variants (P < 5.0 × 10(-8)), 3 of which we found after conditioning on previously identified variants. Thus, there are now 110 established multiple sclerosis risk variants at 103 discrete loci outside of the major histocompatibility complex. With high-resolution Bayesian fine mapping, we identified five regions where one variant accounted for more than 50% of the posterior probability of association. This study enhances the catalog of multiple sclerosis risk variants and illustrates the value of fine mapping in the resolution of GWAS signals.

- Background: Pediatric anxiety disorders are highly prevalent and associated with significant functional disabilities and lifelong morbidity. Cognitive-behavioral therapy (CBT), sertraline, and their combination are effective treatments, but little is known about how these treatments exert their effects.Methods: Using network intervention analysis (NIA), we analyzed data from the largest randomized controlled treatment trial of pediatric anxiety disorders (Child/Adolescent Anxiety Multimodal Study, NCT00052078, clinicaltrials.gov/ct2/show/NCT00052078) and outlined the causal symptom domain-specific effects of CBT, sertraline, and their combination over the course of the 12-week treatment while taking into account both specificity and overlap between symptom dimensions. Results: All active treatments produced positive effects with the most pronounced and consistent effects emerging in relation to psychological distress, family interference, and avoidance. Psychological distress was consistently the most and physical symptoms the least influential symptom domain in the disorder network.Conclusions: All active treatments showed beneficial effects when compared to placebo and NIA identified that these effects were exerted similarly across treatments and primarily through a reduction of psychological distress, family interference, and avoidance. CBT and sertraline may have differential mechanisms of action in relation to psychological distress. Given the lack of causal effects on interference outside family and physical symptoms, interventions tailored to target these domains may aid in the building of more effective treatments. Psychological distress and avoidance should remain key treatment focuses because of their central roles in the disorder network. The findings inform and promote developing more effective interventions. Keywords: CBT/cognitive behavior therapy; anxiety/anxiety disorders; pharmacotherapy; clinical trials; child/adolescent.

- ObjectivePediatric anxiety disorders can have a chronic course and are considered gateway disorders to adult psychopathology, but no consistent predictors of long-term outcome have been identified. A single latent symptom dimension that reflects features shared by all mental health disorders, the p factor, is thought to reflect mechanisms that cut across mental disorders. Whether p predicts outcome in youth with psychiatric disorders has not been examined. We tested whether the p factor predicted long-term psychiatric and functional outcomes in a large naturalistically followed-up cohort of anxiety-disordered youth.MethodYouth enrolled in a randomized controlled treatment trial of pediatric anxiety during childhood/adolescence were followed-up on average six years posttreatment and then annually for four years. Structural equation modeling was used to estimate p at baseline. p and previously established predictors were modeled as predictors of long-term outcome.ResultsHigher levels of p at baseline were related to more mental health disorders, poorer functioning, and greater impairment across all measures at all follow-up time points. p predicted outcome above and beyond previously identified predictors, including diagnostic comorbidity at baseline. Post hoc analyses showed that p predicted long-term anxiety outcomes, but not acute treatment outcome, suggesting that p may be uniquely associated with long-term outcome.ConclusionYouth with anxiety disorders who present with a liability towards broad mental health problems may be at a higher risk for poor long-term outcome across mental health and functional domains. Efforts to assess and address this broad liability may enhance long-term outcome.

- Aim The increasing prevalence of chronic conditions and impairments in the population is putting new demands on health and rehabilitation services. Research on self-help groups suggest that participation in these groups might have a positive impact on people who are struggling with chronic illnesses or disabilities. In this study, we explore person-centred support in which participants in self-help groups are undergoing rehabilitation to develop their knowledge, skills and confidence necessary to handle life's challenges. Method The design is exploratory, analysing data from informant interviews and focus groups (a total of 32 participants) using a Grounded Theory inspired approach to analyse. The participants were rehabilitation clients aged between 20 and 60 years; eight were men and twenty-six were women. Results Three main categories emerged as being important self-help processes that were likely to promote positive rehabilitation outcomes: (1) Learning and practicing safely, (2) A refuge from expectations, (3) Internal processes that accentuate the positives. Conclusion Peer support delivered through the structured self-help environment can facilitate the development of new self-awareness, promote acceptance and adjustment, facilitate the establishment of new skills and enable transfer of learning to new environments, including the workplace.
