Review Meta AnalysisPartial liquid ventilation for preventing death and morbidity in adults with acute lung injury and acute respiratory distress syndrome.
Acute lung injury (ALI), and acute respiratory distress syndrome (ARDS), are syndromes of severe respiratory failure. Adults with ALI or ARDS have high mortality and significant morbidity. Partial liquid ventilation (PLV) may be better (i.e., cause less lung damage) for these patients than other forms of respiratory support. Uncontrolled studies in adults have shown improvement in gas exchange and lung compliance with partial liquid ventilation. ⋯ There is no evidence from randomized controlled trials to support or refute the use of partial liquid ventilation in adults with ALI or ARDS; adequately powered, high quality randomized controlled trials are still needed to assess its efficacy. Clinically relevant outcome measures should be assessed (especially mortality at discharge and later, duration of respiratory support and hospital stay, and long term cognitive and quality of life outcomes) and the studies should be published in full.

Review Meta AnalysisInterventions for primary vesicoureteric reflux.
Vesicoureteric reflux (VUR) results in urine passing, in a retrograde manner, up the ureter. Urinary tract infections (UTIs) have been considered to be the main cause of permanent renal parenchymal damage in children with reflux. Therefore management of these children has been directed at preventing infection by antibiotic prophylaxis and/or surgical correction of reflux. However controversy remains as to the optimum strategies for management of children with primary VUR. ⋯ It is uncertain whether the identification and treatment of children with VUR confers clinically important benefit. The additional benefit of surgery over antibiotics alone is small at best. Assuming a UTI rate of 20% for children with VUR on antibiotics for five years, nine reimplantations would be required to prevent one febrile UTI, with no reduction in the number of children developing any UTI or renal damage.

Review Meta AnalysisLong-term pharmacotherapy for obesity and overweight.
Worldwide prevalence rates of obesity and overweight are rising and safe and effective treatment strategies are urgently needed. A number of anti-obesity agents have been studied in short-term clinical trials, but long-term efficacy and safety need to be established. ⋯ Studies evaluating the long-term efficacy of anti-obesity agents are limited to orlistat and sibutramine. Both drugs appear modestly effective in promoting weight loss; however, interpretation is limited by high attrition rates. Longer and more methodologically rigorous studies of anti-obesity drugs that are powered to examine endpoints such as mortality and cardiovascular morbidity are required to fully evaluate any potential benefit of such agents.

ReviewAromatherapy and massage for symptom relief in patients with cancer.
Aromatherapy massage is a commonly used complementary therapy, and is employed in cancer and palliative care largely to improve quality of life and reduce psychological distress. ⋯ Massage and aromatherapy massage confer short term benefits on psychological wellbeing, with the effect on anxiety supported by limited evidence. Effects on physical symptoms may also occur. Evidence is mixed as to whether aromatherapy enhances the effects of massage. Replication, longer follow up, and larger trials are need to accrue the necessary evidence.

Information is routinely given to pregnant women, but information about caesarean birth may be inadequate. ⋯ Research has focussed on encouraging women to attempt vaginal delivery. Trials of interventions to encourage women to attempt vaginal birth showed no effect, but shortcomings in study design mean that the evidence is inconclusive. Further research on this topic is urgently needed.
