Review Meta AnalysisFirst-line allogeneic hematopoietic stem cell transplantation of HLA-matched sibling donors compared with first-line ciclosporin and/or antithymocyte or antilymphocyte globulin for acquired severe aplastic anemia.
Acquired severe aplastic anemia is a rare and potentially fatal disease, which is characterized by hypocellular bone marrow and pancytopenia. The major signs and symptoms are severe infections, bleeding, and exhaustion. First-line allogeneic hematopoietic stem cell transplantation (HSCT) of a human leukocyte antigen (HLA)-matched sibling donor (MSD) is a treatment for newly diagnosed patients with severe aplastic anemia. First-line treatment with ciclosporin and/or antithymocyte or antilymphocyte globulin (as first-line immunosuppressive therapy) is an alternative to MSD-HSCT and is indicated for patients where no MSD is found. ⋯ There are insufficient and biased data that do not allow any conclusions to be made about the comparative effectiveness of first-line allogeneic hematopoietic stem cell transplantation of an HLA-matched sibling donor and first-line treatment with ciclosporin and/or antithymocyte or antilymphocyte globulin (as first-line immunosuppressive therapy). We are unable to make firm recommendations regarding the choice of intervention for treatment of acquired severe aplastic anemia.

Review Meta AnalysisMass media interventions for reducing mental health-related stigma.
Mental health-related stigma is widespread and has major adverse effects on the lives of people with mental health problems. Its two major components are discrimination (being treated unfairly) and prejudice (stigmatising attitudes). Anti-stigma initiatives often include mass media interventions, and such interventions can be expensive. It is important to know if mass media interventions are effective. ⋯ Mass media interventions may reduce prejudice, but there is insufficient evidence to determine their effects on discrimination. Very little is known about costs, adverse effects or other outcomes. Our review found few studies in middle- and low-income countries, or with employers or health professionals as the target group, and none targeted at children or adolescents. The findings are limited by the quality of the evidence, which was low for the primary outcomes for discrimination and prejudice, low for adverse effects and very low for costs. More research is required to establish the effects of mass media interventions on discrimination, to better understand which types of mass media intervention work best, to provide evidence about cost-effectiveness, and to fill evidence gaps about types of mass media not covered in this review. Such research should use robust methods, report data more consistently with reporting guidelines and be less reliant on student populations.

Review Meta AnalysisEarly versus late administration of amino acids in preterm infants receiving parenteral nutrition.
Observational studies in preterm newborns suggest that delay in administering amino acids could result in a protein catabolic state and could impact on growth and development. ⋯ There is no available evidence of the benefits of early administration of amino acids on mortality, early and late growth and neurodevelopment. There is evidence from four randomised controlled trials included in this review that early administration of amino acids is associated with a positive nitrogen balance. The clinical relevance of this finding is not known. Acid-base status and ammonia levels were normal in the infants who received amino acids early. Given the small number of infants in the randomised controlled trials included in this review, the clinical heterogeneity among them, and the lack of data on important clinical outcomes, there is insufficient evidence to guide practice regarding the early versus late administration of amino acids to infants less than 37 weeks gestation.

Review Meta AnalysisDiet or exercise, or both, for weight reduction in women after childbirth.
Weight retention after pregnancy may contribute to obesity. It is known that diet and exercise are recommended components of any weight loss programme in the general population. However, strategies to achieve healthy body weight among postpartum women have not been adequately evaluated. ⋯ Evidence from this review suggests that both diet and exercise together and diet alone help women to lose weight after childbirth. Nevertheless, it may be preferable to lose weight through a combination of diet and exercise as this improves maternal cardiorespiratory fitness and preserves fat-free mass, while diet alone reduces fat-free mass. This needs confirmation in large trials of high methodological quality. For women who are breastfeeding, more evidence is required to confirm whether diet or exercise, or both, is not detrimental for either mother or baby.
