Review Meta Analysis
Physical activity interventions for people with mental illness: a systematic review and meta-analysis.
To determine effects of physical activity on depressive symptoms (primary objective), symptoms of schizophrenia, anthropometric measures, aerobic capacity, and quality of life (secondary objectives) in people with mental illness and explore between-study heterogeneity. ⋯ Physical activity reduced depressive symptoms in people with mental illness. Larger effects were seen in studies of poorer methodological quality. Physical activity reduced symptoms of schizophrenia and improved anthropometric measures, aerobic capacity, and quality of life among people with mental illness.

Recent, large, randomized controlled trials (RCTs) showed no benefit of long-acting injectable (LAI) antipsychotics over oral antipsychotics in preventing relapse in schizophrenia, nor did a recent meta-analysis incorporating these studies. However, RCTs might enroll a disproportionate number of patients with better treatment adherence and lower illness severity. Mirror-image studies, which compare periods of oral antipsychotic versus LAI treatment in the same patients, might therefore better reflect the real-world impact of LAIs. ⋯ Results from mirror-image studies in patients eligible for clinical use of LAIs showed strong superiority of LAIs compared to oral antipsychotics in preventing hospitalization. The results were in contrast to the recent meta-analysis of RCTs, which showed no superiority of LAIs. Given the possible biases in mirror-image studies, such as expectation bias, natural illness course, and time effect, a cautious interpretation is required. Nevertheless, the population in mirror-image studies better reflects the population receiving LAIs in clinical practice.

Review Meta Analysis
Efficacy and effectiveness of depot versus oral antipsychotics in schizophrenia: synthesizing results across different research designs.
Nonadherence is a major challenge in schizophrenia treatment. While long-acting (depot) antipsychotic medications are often recommended to address adherence problems, evidence on the comparative effectiveness of depot versus oral antipsychotics is inconsistent. We hypothesize that this inconsistency could be due to systematic differences in study design. This review evaluates the effect of study design on the comparative effectiveness of antipsychotic formulations. The optimal use of different antipsychotic formulations in a general clinical setting depends on better understanding of the underlying reasons for differences in effectiveness across research designs. ⋯ The comparative effectiveness of antipsychotic formulations is sensitive to research design. Depot formulations displayed significant advantages in nonrandomized observational studies, whereas in RCTs no difference was observed. The estimated conversion factors may facilitate comparison across studies.

Review Meta Analysis
Antidepressant exposure during pregnancy and congenital malformations: is there an association? A systematic review and meta-analysis of the best evidence.
Depression is often not optimally treated during pregnancy, partially because of conflicting data regarding antidepressant medication risk. This meta-analysis was conducted to determine whether antenatal antidepressant exposure is associated with congenital malformations and to assess the effect of known methodological limitations. ⋯ Overall, antidepressants do not appear to be associated with an increased risk of congenital malformations, but statistical significance was found for cardiovascular malformations. Results were robust in several sensitivity analyses. Given that the RRs are marginal, they may be the result of uncontrolled confounders. Although the RRs were statistically significant, none reached clinically significant levels.

High-frequency repetitive transcranial magnetic stimulation (HF-rTMS) is a safe and effective treatment for major depression. However, its utility as a strategy to accelerate and improve clinical response to antidepressants is still unclear. ⋯ HF-rTMS is a promising strategy for accelerating clinical response to antidepressants in major depression, providing clinically meaningful benefits that are comparable to those of other agents such as triiodothyronine and pindolol. Furthermore, HF-rTMS seems to be an acceptable treatment for depressed subjects.
