This review was performed to test the hypothesis that presymptomatic diagnosis, for example by newborn screening, and early treatment may prevent or reduce irreversible organ damage and thereby improve outcome and quality of life in patients with cystic fibrosis. ⋯ There are few randomised controlled trials assessing the effectiveness of neonatal screening in cystic fibrosis. From the data available at this time, there is little evidence suggesting benefit from screening for cystic fibrosis in the neonatal period, although there is similarly little evidence of harm. This systematic review has identified the need for individual patient data from both included studies. Although we have not been able to perform a meta-analysis, this review provides a summary of all the information currently available from randomised controlled trials on the effectiveness of neonatal screening for cystic fibrosis.

Lung damage associated with persistent infection by Pseudomonas aeruginosa is the major cause of morbidity and mortality in people with cystic fibrosis. Nebulised antibiotics are commonly used for treatment of this infection. ⋯ Nebulised anti-pseudomonal antibiotic treatment improves lung function and reduces frequency of exacerbations of infection in people with cystic fibrosis. There is a need for more evidence for effect on quality of life and survival, for longer duration trials to determine if this benefit is maintained and to determine the significance of development of antibiotic resistant organisms.

ReviewAntiplatelet therapy for preventing stroke in patients with non-valvular atrial fibrillation and no previous history of stroke or transient ischemic attacks.
Atrial fibrillation (AF) carries an increased risk of stroke; antiplatelet agents are proven effective for stroke prevention in other settings. ⋯ Considering all randomized data, aspirin modestly (by about 20%) reduces stroke and major vascular events in nonvalvular AF. For primary prevention among AF patients with an average stroke rate of 4.5%/year, about 10 strokes would be prevented yearly for every 1000 given aspirin.

ReviewDepot flupenthixol decanoate for schizophrenia or other similar psychotic disorders.
Anti-psychotic drugs are the mainstay treatment for schizophrenia and similar psychotic disorders. Long-acting depot injections of drugs such as flupenthixol decanoate are extensively used as a means of long-term maintenance treatment. ⋯ From the data reported in clinical trials, it would be understandable if those suffering from schizophrenia, who are willing to take flupenthixol decanoate, would request the standard dose rather than the high dose. In the current state of evidence, there is nothing to choose between flupenthixol decanoate and other depot antipsychotics. The choice of which depot to use must therefore be based on clinical judgement and the preferences of people with schizophrenia and their carers. Managers and policy makers should expect better data than the research community has provided thus far. This review highlighted the need for large, well-designed and reported randomised clinical trials to address the effects of flupenthixol decanoate, in particular when compared to oral antipsychotics. Future studies should also consider hospital and service outcomes, satisfaction with care and record economic data.

ReviewMedical anti-shock trousers (pneumatic anti-shock garments) for circulatory support in patients with trauma.
Medical antishock trousers (MAST) have been used to increase venous return to the heart until definitive care could be given. This, combined with compression of blood vessels, is believed to cause the movement of blood from the lower body to the brain, heart and lungs. However, the equipment is expensive, and may have adverse effects. ⋯ There is no evidence to suggest that MAST/PASG application reduces mortality, length of hospitalisation or length of ICU stay in trauma patients and it is possible that it may increase these. These data do not support the continued use of MAST/PASG in the situation described. However, it should be recognised that, due to the poor quality of the trials, conclusions should be drawn with caution.
