Review Meta AnalysisLay health workers in primary and community health care for maternal and child health and the management of infectious diseases.
Lay health workers (LHWs) are widely used to provide care for a broad range of health issues. Little is known, however, about the effectiveness of LHW interventions. ⋯ LHWs provide promising benefits in promoting immunisation uptake and breastfeeding, improving TB treatment outcomes, and reducing child morbidity and mortality when compared to usual care. For other health issues, evidence is insufficient to draw conclusions about the effects of LHWs.

Review Meta AnalysisAnthelmintics for people with neurocysticercosis.
Neurocysticercosis is an infection of the brain by the larval stage of the pork tapeworm. In endemic areas it is a common cause of epilepsy. Anthelmintics (albendazole or praziquantel) may be given to kill the parasites. However, there are potential adverse effects, and the parasites may eventually die without treatment. ⋯ In patients with viable lesions, evidence from trials of adults suggests albendazole may reduce the number of lesions. In trials of non-viable lesions, seizure recurrence was substantially lower with albendazole, which is counter-intuitive. It may be that steroids influence headache during treatment, but further research is needed to test this.

Review Meta AnalysisTailored interventions to overcome identified barriers to change: effects on professional practice and health care outcomes.
In the previous version of this review, the effectiveness of interventions tailored to barriers to change was found to be uncertain. ⋯ Interventions tailored to prospectively identified barriers are more likely to improve professional practice than no intervention or dissemination of guidelines. However, the methods used to identify barriers and tailor interventions to address them need further development. Research is required to determine the effectiveness of tailored interventions in comparison with other interventions.

Review Meta AnalysisAntidepressants for depression in physically ill people.
There is an increased risk of depression in people with a physical illness. Depression is associated with reduced treatment adherence, poor prognosis, increased disability and higher mortality in many physical illnesses. Antidepressants are effective in the treatment of depression in physically healthy populations, but there is less clarity regarding their use in physically ill patients. This review updates Gill's Cochrane review (2000), which found that antidepressants were effective for depression in physical illness. Since Gill there have been a number of larger trials assessing the efficacy of antidepressants in this context. ⋯ This review provides evidence that antidepressants are superior to placebo in treating depression in physical illness. However, it is likely that publication and reporting biases exaggerated the effect sizes obtained. Further research is required to determine the comparative efficacy and acceptability of particular antidepressants in this population.

Review Meta AnalysisEarly psychological interventions to treat acute traumatic stress symptoms.
The amelioration of psychological distress following traumatic events is a major concern. Systematic reviews suggest that interventions targeted at all of those exposed to such events are not effective at preventing post traumatic stress disorder (PTSD). Recently other forms of intervention have been developed with the aim of treating acute traumatic stress problems. ⋯ There was evidence that individual TF-CBT was effective for individuals with acute traumatic stress symptoms compared to both waiting list and supportive counselling interventions. The quality of trials included was variable and sample sizes were often small. There was considerable clinical heterogeneity in the included studies and unexplained statistical heterogeneity observed in some comparisons. This suggests the need for caution in interpreting the results of this review. Additional high quality trials with longer follow up periods are required to further test TF-CBT and other forms of psychological intervention.
