ReviewOrientation and mobility training for adults with low vision.
Orientation and mobility (O&M) training is provided to people who are visually impaired to help them maintain travel independence, teaching them new orientation and mobility skills to compensate for reduced visual information. ⋯ We could not find any controlled trials on the effects of orientation and mobility training for adults with low vision. As a premise to future trials, orientation and mobility instructors and scientists should reach a consensus and develop valid measures of mobility performance which are both reliable and meaningful to people with low vision.

ReviewEarly intravenous nutrition for the prevention of neonatal jaundice.
The early institution of enteral feeding in the first few days of life is known to impact on the development of unconjugated hyperbilirubinaemia. However, the effect of early intravenous nutrition on neonatal jaundice remains unknown. ⋯ Decisions regarding the institution of early intravenous nutrition must continue to be based upon factors others than its effect on neonatal jaundice.

Head injury increases the body's metabolic responses, and therefore nutritional demands. Provision of an adequate supply of nutrients is associated with improved outcome. The best route for administering nutrition (parenterally (TPN) or enterally (EN)), and the best timing of administration (e.g early versus late) of nutrients needs to be established. ⋯ This review suggests that early feeding may be associated with a trend towards better outcomes in terms of survival and disability. Further trials are required. These trials should report not only nutritional outcomes but also the effect on death and disability.

Review Meta AnalysisProphylactic antibiotic administration in pregnancy to prevent infectious morbidity and mortality.
Some previous studies suggested that prophylactic antibiotics given during pregnancy improved maternal and perinatal outcomes, some did not show any benefit and some even reported adverse effects. ⋯ Antibiotic prophylaxis given during the second or third trimester of pregnancy reduces the risk of prelabour rupture of the membranes when given routinely to pregnant women. Beneficial effects on birth weight and the risk of postpartum endometritis were seen for high risk women.

ReviewExtracorporeal membrane oxygenation for severe respiratory failure in newborn infants.
Extracorporeal membrane oxygenation (ECMO) is a complex procedure of life support in severe but potentially reversible respiratory failure, used particularly in mature newborn infants. Although the number of babies requiring ECMO is small, and the ECMO policy invasive and potentially expensive, its benefits may be high. ⋯ A policy of using ECMO in mature infants with severe but potentially reversible respiratory failure would result in significantly improved survival without increased risk of severe disability amongst survivors. For babies with diaphragmatic hernia ECMO offers short term benefits but the overall effect of employing ECMO in this group is not clear. Further studies are needed to refine ECMO techniques; to consider the optimal timing for introducing ECMO; to identify which infants are most likely to benefit; and to address the longer term implications of neonatal ECMO during later childhood and adult life.
