Review Meta AnalysisLong-chain polyunsaturated fatty acid supplementation in infants born at term.
The n-3 and n-6 fatty acids linolenic acid and linoleic acid are precursors of the n-3 and n-6 long chain fatty acids (LCPUFA). Infant formula has historically only contained the precursor fatty acids. Controversy exists over whether LCPUFA are also essential nutrients in infancy. Over the last few years, some manufacturers have added LCPUFA to formulae and marketed them as providing an advantage for the development of term infants. ⋯ The results of most of the well conducted RCTS have not shown beneficial effects of LCPUFA supplementation of formula milk on the physical, visual and neurodevelopmental outcomes of infants born at term. Only one group of researchers have shown some beneficial effects on VEP acuity. Two groups of researchers have shown some beneficial effect on mental development. Routine supplementation of milk formula with LCPUFA to improve the physical, neurodevelopmental or visual outcomes of infants born at term can not be recommended based on the current evidence. Further research is needed to see if the beneficial effects demonstrated by Dallas 2005 trial of Birch et al can be replicated in different settings.

Review Meta AnalysisBiocompatible hemodialysis membranes for acute renal failure.
Acute renal failure (ARF) is associated with substantial morbidity and mortality. Some studies have reported a survival advantage among patients dialyzed with biocompatible membranes (BCM) compared to bioincompatible membranes (BICM). These findings were not consistently observed in subsequent studies. ⋯ There is no demonstrable clinical advantage to the use of BCM versus BICM in patients with ARF who require intermittent hemodialysis.

Review Meta AnalysisPregabalin add-on for drug-resistant partial epilepsy.
Epilepsy is a common chronic neurological disease with an estimated prevalence of 1% in the United Kingdom. Approximately a third of these people continue to have seizures despite drug treatment. In order to try to improve outcomes a number of new antiepileptic drugs have been developed and pregabalin is one of these. ⋯ Pregabalin, when used as an add-on drug for treatment-resistant partial epilepsy, is significantly more effective than placebo at achieving a 50% or greater seizure reduction. Results demonstrate efficacy for doses from 150 mg to 600 mg per day, with no evidence for plateauing of effect at the doses tested. The trials included in this review were of short duration and longer term trials are needed to better inform clinical decision making.

Peripheral arterial disease (PAD) affects 4% to 12% of people aged 55 to 70 years and 20% of people over 70 years. The most common complaint is intermittent claudication (IC) characterised by pain in the legs or buttocks that occurs with exercise and which subsides with rest. Compared with age-matched controls, people with IC have a three- to six-fold increase in cardiovascular mortality. Symptoms of IC, walking distance, and quality of life can be improved by risk factor modification, smoking cessation, and a structured exercise program. Antiplatelet treatment is beneficial in patients with IC for the reduction of vascular events but has not been shown to influence claudication distance. ⋯ Patients with IC should receive secondary prevention for cardiovascular disease. Cilostazol has been shown to be of benefit in improving walking distance in people with IC. There are no data on whether it results in a reduction of adverse cardiovascular events.

Review Meta AnalysisTreatment foster care for improving outcomes in children and young people.
Treatment foster care (TFC) is a foster family-based intervention that aims to provide young people (and, where appropriate, their families) with a tailored programme designed to effect positive changes in their lives. TFC was designed specifically to cater for the needs of children whose difficulties or circumstances place them at risk of multiple placements and/or more restrictive placements such as hospital or secure residential or youth justice settings. ⋯ Although the inclusion criteria for this systematic review set a study design threshold higher than that of previous reviews, the results mirror those of earlier reviews but also highlights the tendency of the perceived effectiveness of popular interventions to outstrip their evidence base. Whilst the results of individual studies generally indicate that TFC is a promising intervention for children and youth experiencing mental health problems, behavioural problems or problems of delinquency, the evidence base is less robust than that usually reported.
