ReviewOral anticoagulants for preventing stroke in patients with non-valvular atrial fibrillation and no previous history of stroke or transient ischemic attacks.
Non-valvular atrial fibrillation (AF) is associated with an increased risk of stroke. ⋯ Adjusted-dose OAC (achieved INRs between 2-3) reduces stroke as well as disabling/fatal stroke for patients with nonvalvular AF, and these benefits were not substantially offset by increased bleeding among participants in randomized clinical trials. Limitations include relatively short follow-up and imprecise estimates of bleeding risks from these selected participants. For primary prevention in AF patients who have an average stroke rate of 4%/year, about 25 strokes and about 12 disabling fatal strokes would be prevented yearly for every 1000 given OAC.

Amniotomy (deliberate rupture of the membranes) is a simple procedure which can be used alone for induction of labour if the membranes are accessible, thus avoiding the need for pharmacological intervention. However, the time interval from amniotomy to established labour may not be acceptable to clinicians and women, and in a number of cases labour may not ensue. This is one of a series of reviews of methods of cervical ripening and labour induction using standardised methodology. ⋯ Data is lacking about the value of amniotomy alone for induction of labour. While there are now other modern methods available for induction of labour (pharmacological agents), there remain clinical scenarios where amniotomy alone may be desirable and appropriate, and this method is worthy of further research. This research should include evaluation of the appropriate time interval from amniotomy to secondary intervention, women and caregivers' satisfaction and economic analysis.

Review Comparative StudyDietary marine fatty acids (fish oil) for asthma.
Epidemiological studies suggest that a diet high in marine fatty acids (fish oil) may have beneficial effects on inflammatory conditions such as rheumatoid arthritis and possibly asthma. ⋯ There is little evidence to recommend that people with asthma supplement or modify their dietary intake of marine n-3 fatty acids (fish oil) in order to improve their asthma control. Equally, there is no evidence that they are at risk if they do so.

This review is superseded by the published Cochrane Review, Taylor 2023: https://www.cochranelibrary.com/cdsr/doi/10.1002/14651858.CD014785.pub2/full. ⋯ Given the level of investment in growth monitoring worldwide, it is surprising there is so little research evaluating its potential benefits and harms.

Neisseria gonorrhoeae can be transmitted from the mother's genital tract to the newborn during birth and can cause gonococcal opthalmia neonatorum. ⋯ Any of the antibiotic regimens tested in these trials appear to be effective for the treatment of gonorrhoea in pregnancy in terms of their effect on microbiological cure. For women who are allergic to penicillin, this review provides reassurance that treatment with ceftriaxone or spectinomycin appears to be at least as equally effective in producing microbiological cure.
