ReviewPositive expiratory pressure physiotherapy for airway clearance in people with cystic fibrosis.
Chest physiotherapy is widely prescribed to assist the clearance of airway secretions in people with cystic fibrosis (CF). Positive expiratory pressure (PEP) devices provide constant back pressure to the airways during expiration. This may improve clearance by building up gas behind mucus via collateral ventilation. Given the widespread use of PEP devices, there is a need to determine the evidence for their effect. ⋯ There was no clear evidence that PEP was a more or less effective intervention overall than other forms of physiotherapy. There was limited evidence that PEP was preferred by participants compared to other techniques but this finding is from studies of low quality.

Antipsychotic drugs are the mainstay treatment for schizophrenia. Long-acting depot injections of drugs such as bromperidol decanoate are extensively used as a means of long-term maintenance treatment. ⋯ Currently, minimal poorly reported trial data suggests that bromperidol decanoate may be better than placebo injection but less valuable than fluphenazine or haloperidol decanoate. If bromperidol decanoate is available it may be a viable choice, especially when there are reasons not to use fluphenazine or haloperidol decanoate. Well-conducted and reported randomised trials are needed to inform practice in Belgium, Germany, Italy and the Netherlands.

ReviewZuclopenthixol acetate for acute schizophrenia and similar serious mental illnesses.
Medication used for acute aggression in psychiatry must have rapid onset of effect, low frequency of administration and low levels of adverse effects. Zuclopenthixol acetate is said to have these properties. ⋯ Recommendations on the use of zuclopenthixol acetate for the management of psychiatric emergencies in preference to 'standard' treatment have to be viewed with caution. Most trials present important methodological flaws and findings are poorly reported. This review did not find any suggestion that zuclopenthixol acetate is more or less effective in controlling aggressive acute psychosis, or in preventing adverse effects than intramuscular haloperidol, and neither seemed to have a rapid onset of action. Well-conducted pragmatic randomised controlled trials are needed.

The prevalence of chronic heart failure is increasing, and increases with increasing age. Major symptoms include breathlessness and restricted activities of daily living due to reduced functional capacity, which in turn affects quality of life. Exercise training has been shown to be effective in patients with coronary heart disease and has been proposed as an intervention to improve exercise tolerance in patients with heart failure. ⋯ Exercise training improves exercise capacity and quality of life in patients mild to moderate heart failure in the short term. There is currently no information regarding the effect of exercise training on clinical outcomes. The findings are based on small-scale trials in patients who are unrepresentative of the total population of patients with heart failure. Other groups (more severe patients, the elderly, women) may also benefit. Large-scale pragmatic trials of exercise training of longer duration, recruiting a wider spectrum of patients are needed to address these issues.

Thrombolytic therapy is a useful tool in the management of acute peripheral arterial ischaemia. Fibrinolytic drugs are used to disperse blood clot to clear arterial occlusion. A variety of techniques are used to deliver these agents. ⋯ Implications for practice Thrombolysis should be reserved for patients with limb threatening ischaemia, due to the high risk of haemorrhage or death. Greater benefit is seen when the thrombolytic agent is delivered into the thrombus. Systemic intravenous thrombolysis is less effective than intra-arterial thrombolysis and is associated with an increase in bleeding complications. 'High dose' and 'forced infusion' techniques, or adjunctive agents such as platelet glycoprotein IIb/IIIa inhibitors may speed up thrombolysis, but these are not accompanied by lower amputation rates or a decreased need for adjunctive endovascular or surgical procedures. 'Low dose continuous infusion', following initial lacing of the thrombus with a high dose of the thrombolytic agent, is the least labour intensive technique. Implications for research Only large multicentre trials with carefully controlled inclusion criteria will be sufficiently powerful to demonstrate genuine benefit for a particular thrombolytic regime.
