ReviewHigh-frequency ventilation versus conventional ventilation for treatment of acute lung injury and acute respiratory distress syndrome.
High-frequency ventilation is often used to treat patients with acute lung injury (ALI) or acute respiratory distress syndrome (ARDS) but the effect of this treatment on clinical outcomes has not been well established. ⋯ There is not enough evidence to conclude whether high-frequency ventilation reduces mortality or long-term morbidity in patients with ALI or ARDS; further trials are needed.

ReviewBenzo-pyrones for reducing and controlling lymphoedema of the limbs.
Lymphoedema is the accumulation of excess fluid in the body caused by obstruction of the lymphatic drainage mechanisms. It can be caused by a number of factors, including congenital predisposition, parasitic infection or surgery. Lymphoedema is chronic and progressive and affects a significant proportion of the population. The standard treatment regimes include compression hosiery, skin care and exercise. The use of drugs in treatment, particularly benzo-pyrones, has gained favour over the last ten years. Benzo-pyrones, originally developed for use in vascular medicine, are prescribed to reduce vascular permeability and thus the amount of fluid forming in the subcutaneous tissues. Advocates for this treatment method believe that, as a result of reducing filtration, the drugs have some beneficial effect on pain and discomfort in the swollen areas. Proponents also claim that these drugs increase macrophage activity, encouraging the lysis of protein, which in turn reduces the formation of fibrotic tissue in the lymphoedematous limb. ⋯ Meta-analysis was not performed due to the poor quality of the trials. It is not possible to draw conclusions about the effectiveness of Benzopyrones in reducing limb volume, pain, or discomfort in lymphoedematous limbs from these trials.

ReviewInterventions for improving adherence to treatment in patients with high blood pressure in ambulatory settings.
Lack of adherence to blood pressure lowering medication is a major reason for poor control of hypertension worldwide. Interventions to improve adherence to antihypertensive medication have been evaluated in randomised trials but it is unclear which interventions are effective. ⋯ Reducing the number of daily doses appears to be effective in increasing adherence to blood pressure lowering medication and should be tried as a first line strategy, although there is less evidence of an effect on blood pressure reduction. Some motivational strategies and complex interventions appear promising, but we need more evidence on their effect through carefully designed RCTs.

ReviewBenzodiazepine receptor antagonists for hepatic encephalopathy.
Hepatic encephalopathy may be associated with accumulation of substances that bind to a receptor-complex in the brain resulting in neural inhibition. Benzodiazepine receptor antagonists may have a beneficial effect on patients with hepatic encephalopathy. ⋯ Flumazenil had a significant beneficial effect on short-term improvement of hepatic encephalopathy in patients with cirrhosis and a highly favourable prognosis. Flumazenil had no significant effect on recovery or survival. Considering the fluctuating nature of hepatic encephalopathy, future trials should use a parallel design and assess if treatment with flumazenil leads to a sustained improvement or increased recovery and survival. Until this has been demonstrated, flumazenil may be considered for patients with chronic liver disease and hepatic encephalopathy, but cannot be recommended for routine clinical use.

ReviewCommunication skills training for health care professionals working with cancer patients, their families and/or carers.
Research suggests communication skills do not reliably improve with experience. Considerable effort is dedicated to courses improving communication skills for health professionals. Evaluation of such courses is important to enable evidence-based teaching and practice. ⋯ Training programmes assessed by these trials appear to be effective in improving some areas of cancer care professionals communication skills. It is unknown whether this training would be effective if taught by others, nor the comparative efficacy of these programmes.
