Review Meta AnalysisOmega-3 fatty acids for intermittent claudication.
Omega-3 fatty acids are established as being effective in the treatment and prevention of coronary artery disease. It is possible that they may also benefit people with peripheral arterial disease, since the pathogenesis of the two conditions is similar. ⋯ Omega-3 fatty acids appear to have some beneficial biochemical and haemodynamic effects in people with intermittent claudication but there is no evidence of improved clinical outcomes. It should be noted that no consistent effect on primary outcome measures was detected. Further research is needed in this area, to evaluate short- and long-term effects on more clinically relevant outcomes.

Review Meta AnalysisSemen preparation techniques for intrauterine insemination.
Semen preparation techniques for assisted reproduction, including intrauterine insemination (IUI), were developed to separate the motile morphological normal spermatozoa. Leucocytes, bacteria and dead spermatozoa produce oxygen radicals that negatively influence the ability to fertilize the egg. The yield of as many motile, morphologically normal spermatozoa might influence treatment choices and therefore outcomes. ⋯ There is insufficient evidence to recommend any specific preparation technique. Large high quality randomised controlled trials, comparing the effectiveness of a gradient and/ or a swim-up and/ or wash and centrifugation technique on clinical outcome are lacking. Further randomised trials are warranted. Results from studies comparing semen parameters may suggest a preference for gradient technique, but firm conclusions cannot be drawn and the limitations should be taken into consideration.

Review Meta AnalysisAnaesthesia for hip fracture surgery in adults.
The majority of people with hip fracture are treated surgically, requiring anaesthesia. ⋯ Overall, there was insufficient evidence available from trials comparing regional versus general anaesthesia to rule out clinically important differences. Regional anaesthesia may reduce acute postoperative confusion but no conclusions can be drawn for mortality or other outcomes.

Review Meta AnalysisTelephone consultation and triage: effects on health care use and patient satisfaction.
Telephone consultation is the process where calls are received, assessed and managed by giving advice or by referral to a more appropriate service. In recent years there has been a growth in telephone consultation developed, in part, as a response to increased demand for General Practitioner (GP) and Accident and Emergency (A&E) department care. ⋯ Telephone consultation appears to reduce the number of surgery contacts and out-of-hours visits by general practitioners. However, questions remain about its affect on service use and further rigorous evaluation is needed with emphasis on service use, safety, cost and patient satisfaction.

Lupus nephritis is the renal manifestation of systemic lupus erythematosus (SLE) - a disease mainly affecting young women with substantial morbidity and mortality. It is classified by the World Health Organization (WHO) criteria I - VI based on histology. WHO Class IV is a diffuse proliferative glomerulonephritis which has the worst prognosis without treatment, with a reported 17% five year survival in the era 1953-1969. This survival was 82% in the early 1990's and continues to improve. An important factor behind this has been the use of cytotoxics such as cyclophosphamide in addition to steroids. ⋯ Until future RCTs of newer agents are completed, the current use of cyclophosphamide combined with steroids remains the best option to preserve renal function in proliferative LN. The smallest effective dose and shortest duration of treatment should be used to minimise gonadal toxicity, without compromising efficacy.
