Fuelling the debate on e-cigarettes

- Featured Image

E-cigarettes continue to divide opinion (resulting in some strange bedfellows), but there is emerging evidence that they are a beneficial aid to stopping smoking and reducing consumption. The first version of what is likely to be a frequently updated review included two randomised trials involving 662 smokers that compared e-cigarettes with and without nicotine. About 9% of smokers who used nicotine e-cigarettes had stopped smoking for at least 6 months, compared with 4% of those using nicotine-free e-cigarettes. Nicotine e-cigarettes were also more effective than placebo e-cigarettes in enabling participants to halve cigarette consumption rates (doi: 10.1002/14651858.CD010216.pub2). There is not yet sufficient evidence to properly compare e-cigarettes with other quitting aids.

A recent review of point-of-care biomarker testing sounds a cautiously optimistic note in the fight against antibiotic resistance. Six trials involving over 3200 mostly adult patients with acute respiratory infections were reviewed. All investigated the use of C-reactive protein tests to guide antibiotic prescribing in primary care. Encouragingly, doctors who test for the presence of bacterial infections were likely to prescribe fewer antibiotics, and no difference was found between the two groups in terms of how long patients took to recover (doi: 10.1002/14651858.CD010130.pub2).
