Review Meta Analysis Comparative StudyExtra-abdominal versus intra-abdominal repair of the uterine incision at caesarean section.
Different techniques have been described to reduce morbidity during caesarean section. After the baby has been born by caesarean section and the placenta has been extracted, temporary removal of the uterus from the abdominal cavity (exteriorisation of the uterus) to facilitate repair of the uterine incision has been postulated as a valuable technique. This is particularly so when exposure of the incision is difficult and when there are problems with haemostasis. Several clinical trials have been done, with varying results, including substantial reduction in the rate of postoperative infection and morbidity with extra-abdominal closure of the uterine incision, and less associated peri-operative haemorrhage. Subsequent studies suggest that the method of placental removal rather than method of closure of the uterine incision influences peri-operative morbidity. ⋯ There is no evidence from this review to make definitive conclusions about which method of uterine closure offers greater advantages, if any. However, these results are based on too few and too small studies to detect differences in rare, but severe, complications.

Circumcision is a painful procedure that many newborn males undergo in the first few days after birth. Interventions are available to reduce pain at circumcision; however, many newborns are circumcised without pain management. ⋯ DPNB was the most frequently studied intervention and was the most effective for circumcision pain. Compared to placebo, EMLA was also effective, but was not as effective as DPNB. Both interventions appear to be safe for use in newborns. None of the studied interventions completely eliminated the pain response to circumcision.

Review Meta AnalysisLow glycaemic index diets for coronary heart disease.
The glycaemic index (GI) is a physiological measure of the ability of a carbohydrate to affect blood glucose. Interest is growing in the low GI carbohydrate concept for the clinical management of people at risk of, or with established coronary heart disease. There is a need to review the current evidence from controlled trials in this area. ⋯ The evidence from randomised controlled trials showing that low glycaemic index diets reduces coronary heart disease and CHD risk factors is weak. Many of the trials identified were short-term, of poor quality and conducted on small sample sizes. There is a need for well designed, adequately powered, randomised controlled studies, of greater than 12 weeks duration to assess the effects of low glycaemic index diets for CHD.

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 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.
