Review Meta AnalysisTreatment for women with postpartum iron deficiency anaemia.
Postpartum anaemia is associated with breathlessness, tiredness, palpitations and maternal infections. Blood transfusions or iron supplementation have been used in the treatment of iron deficiency anaemia. Recently other anaemia treatments, in particular erythropoietin therapy, have also been used. ⋯ There is some limited evidence of favourable outcomes for treatment of postpartum anaemia with erythropoietin. However, most of the available literature focuses on laboratory haematological indices, rather than clinical outcomes. Further high-quality trials assessing the treatment of postpartum anaemia with iron supplementation and blood transfusions are required. Future trials may also examine the significance of the severity of anaemia in relation to treatment, and an iron-rich diet as an intervention.

Review Meta AnalysisOmega 3 fatty acids for prevention and treatment of cardiovascular disease.
It has been suggested that omega 3 (W3, n-3 or omega-3) fats from oily fish and plants are beneficial to health. ⋯ It is not clear that dietary or supplemental omega 3 fats alter total mortality, combined cardiovascular events or cancers in people with, or at high risk of, cardiovascular disease or in the general population. There is no evidence we should advise people to stop taking rich sources of omega 3 fats, but further high quality trials are needed to confirm suggestions of a protective effect of omega 3 fats on cardiovascular health. There is no clear evidence that omega 3 fats differ in effectiveness according to fish or plant sources, dietary or supplemental sources, dose or presence of placebo.

Review Meta AnalysisSelenium supplementation for critically ill adults.
Selenium is a trace mineral essential to human health, which has an important role in the immune response, defence against tissue damage and thyroid function. Improving selenium status could help protect against overwhelming tissue damage and infection in critically ill adults. ⋯ There is insufficient evidence to recommend supplementation of critically ill patients with selenium or ebselen. Trials are required which overcome the defects of the reviewed studies, particularly inadequate size and methodology. This review will be updated when four ongoing trials are completed.

Review Meta AnalysisAntibiotic regimens for suspected early neonatal sepsis.
Early acquired infection may cause severe illness or death in the neonatal period. Prompt treatment with antibiotics has shown to reduce mortality. It is not clear which antibiotic regimen is suitable for treatment of presumed early neonatal sepsis. ⋯ There is no evidence from randomised trials to suggest that any antibiotic regimen may be better than any other in the treatment of presumed early neonatal sepsis. More studies are needed to resolve this issue.

Review Meta AnalysisDiscontinuation of epidural analgesia late in labour for reducing the adverse delivery outcomes associated with epidural analgesia.
Although epidural analgesia provides the most effective labour analgesia, it is associated with some adverse obstetric consequences, including an increased risk of instrumental delivery. Many centres discontinue epidural analgesia late in labour to improve a woman's ability to push and reduce the rate of instrumental delivery. ⋯ There is insufficient evidence to support the hypothesis that discontinuing epidural analgesia late in labour reduces the rate of instrumental delivery. There is evidence that it increases the rate of inadequate pain relief in the second stage of labour. The practice of discontinuing epidurals is widespread and the size of the reduction in instrumental delivery rate could be clinically important; therefore, we recommend a larger study than those included in this review be undertaken to determine whether this effect is real or has occurred by chance, and to provide stronger evidence about the safety aspects.
