ReviewIntratracheal Clara cell secretory protein (CCSP) administration in preterm infants with or at risk of respiratory distress syndrome.
Clara cell secretary protein (CCSP) is an immune-modulating and anti-inflammatory agent. CCSP is available synthetically as recombinant human Clara cell protein (rhCC10). It has been shown in animal models to reduce lung injury, improve pulmonary compliance and oxygenation, decrease systemic inflammation and up-regulate surfactant protein and vascular endothelial growth factor expression. These properties makes intratracheally administered CCSP a potential agent in prevention of chronic lung disease (CLD). ⋯ There are insufficient data to determine the role of rhCC10 in clinical practice. Further studies are required to determine if rhCC10 reduces lung inflammation in infants at risk of CLD, and to determine dose and dosing strategy.

Non-specialist health worker interventions for mental health care in low- and middle- income countries.
This is the protocol for a review and there is no abstract. The objectives are as follows: ⋯ In order to assess the impact of delivery by non-specialist health workers (NSHWs) and other professionals with health roles (OPHRs) on the effectiveness of mental healthcare interventions in low- and middle- income countries (LMICs), we will specifically analyse the effectiveness of NSHWs and OPHRS in delivering acute mental health interventions; as well as the effectiveness of NSHWs and OPHRs in delivering long term follow-up and rehabilitation for people with mental disorders; and the effect of the detection of mental disorders by NSHWs and OPHRs on patient and health delivery outcomes. For each of these objectives we will examine the current evidence for the impact of delivery by NSHWs and OPHRs on the resource use and costs associated with mental healthcare provision in LMICs.

Review Meta AnalysisWITHDRAWN: Interventions for preventing ankle ligament injuries.
Some sports, for example basketball and soccer, have a very high incidence of ankle injuries, mainly sprains. Consequently, ankle sprains are one of the most commonly treated injuries in acute care. ⋯ This review provides good evidence for the beneficial effect of ankle supports in the form of semi-rigid orthoses or air-cast braces to prevent ankle sprains during high-risk sporting activities (e.g. soccer, basketball). Participants with a history of previous sprain can be advised that wearing such supports may reduce the risk of incurring a future sprain. However, any potential prophylactic effect should be balanced against the baseline risk of the activity, the supply and cost of the particular device, and for some, the possible or perceived loss of performance.Further research is indicated principally to investigate other prophylactic interventions, their cost-effectiveness and general applicability.

Selenium is a trace element essential to humans. Higher selenium exposure and selenium supplements have been suggested to protect against several types of cancers. ⋯ No reliable conclusions can be drawn regarding a causal relationship between low selenium exposure and an increased risk of cancer. Despite evidence for an inverse association between selenium exposure and the risk of some types of cancer, these results should be interpreted with care due to the potential limiting factors of heterogeneity and influences of unknown biases, confounding and effect modification.The effect of selenium supplementation from RCTs yielded inconsistent results. To date, there is no convincing evidence that selenium supplements can prevent cancer in men, women or children.

Review Meta AnalysisAntiretroviral therapy for prevention of HIV transmission in HIV-discordant couples.
Antiretroviral drugs have been shown to reduce risk of mother-to-child transmission of human immunodeficiency virus (HIV) and are also widely used for post-exposure prophylaxis for parenteral and sexual exposures. Observational data, ecological studies and models suggest that sexual transmission may be lower in couples in which one partner is infected with HIV and the other is not and the infected partner is on antiretroviral therapy (ART). ⋯ ART appears to be a potent intervention for prevention of HIV in discordant couples. However, the most important question from a clinical standpoint is whether being in a serodiscordant sexual relationship and having >350 CD4 cells/µL should be an indication for ART. In our analysis, there were broad confidence intervals in this subgroup, overlapping the null hypothesis of no effect. There is currently one large randomised controlled trial in the field, whose results are scheduled to be ready in 2015. Significant questions remain about durability of protection, when to start treating an infected partner (for instance, at diagnosis or at a specific CD4 level) and transmission of ART-resistant strains to partners.
