    B-vitamin supplements should not be recommended for prevention of heart disease, say scientists. A Cochrane Systematic Review has shown these supplements do not reduce the risk of developing or dying from the disease.“There is no evidence to support the use of B-vitamins as supplements for reducing the risk of heart attack, stroke or death associated with cardiovascular disease,” says lead researcher, Arturo Martí-Carvajal of the Iberoamerican Cochrane Network in Valencia, Venezuela. “And it...

    More research is required to establish whether Chinese herbal medicines can reduce the likelihood of developing diabetes, according to Cochrane Researchers. Although herbal medicines are widely used in Asian countries to treat pre-diabetes (impaired glucose tolerance or IGT), the precursor of the disease, researchers say there is still not enough hard scientific evidence to confidently recommend their use.“People with impaired glucose tolerance are more likely to develop full blown diabetes...

    New, less invasive surgical treatments for stress urinary incontinence in women are just as effective as traditional open surgical approaches, according to Cochrane Researchers. The researchers carried out a systematic review of trials comparing different surgical approaches to treating the condition.A third of women suffer from stress urinary incontinence. As well as the social distress involved, the condition places a significant financial burden on health systems and individuals. Surgery is...

    Rapid viral diagnosis tests for respiratory diseases in children who arrive in emergency departments have the potential to reduce pressures on health systems by enabling doctors to reach a quicker diagnosis, according to Cochrane Researchers. However, they say larger trials are needed to confirm this finding.“The existing evidence is not strong enough to prove that these tests help to reduce pressure on health systems, but it certainly does look promising,” said lead researcher, Quynh Doan of...

    Area-wide traffic calming schemes that discourage through-traffic from using residential roads are effective at reducing traffic-related injuries in high-income countries and may even reduce deaths. However, more research needs to be carried out to see whether these interventions will work in low- and middle-income countries, according to a Cochrane Systematic Review of the available evidence. Each year, 1.23 million people die in road traffic accidents. Over the next decade, road deaths...

    Aiming for lower than standard blood pressure targets offers no known clinical benefit, according to a Cochrane Review. In a systematic review of the evidence, researchers found that using antihypertensive drugs to reduce blood pressure below the 140/90 mm Hg standard was not associated with any reduction in death rates or serious morbidity.“At present there is no evidence from randomized trials to support aiming for a blood pressure target lower than 140/90, in the general population of...

    There is not enough evidence to support using gels and creams containing rubefacients for chronic and acute pain, according to a systematic review by Cochrane Researchers. Rubefacients cause irritation and reddening of the skin, due to increased blood flow. The review focused on formulations containing salicylates, which are widely prescribed or sold over the counter as topical treatments for sports injuries and muscle pain.“At present, due to a lack of high quality evidence, we can’t say...

    Parental acupuncture, clown doctors, hypnotherapy, low sensory stimulation and hand-held video games are promising non-drug interventions that are likely to help reduce children’s anxiety during the onset of their anaesthetic, is the main conclusion of a new Cochrane Systematic Review.The review was conducted because undergoing a general anaesthetic can be a frightening experience for a young child and distressing to parents. Children can be given a “premed” to sedate them when anaesthesia is...

    Antimicrobial treatments for bacterial vaginosis (BV) are effective, but taking lactobacillus tablets alongside metronidazole antibiotic therapy increases effectiveness over taking this antibiotic alone, according to a Cochrane Systematic Review. The researchers also concluded that intravaginal lactobacillus was as effective as oral metronidazole, although they did note unexplained drop-outs from the trials.BV is a very common vaginal infection. Traditionally, antibiotics in tablet or gel form...

    Giving a local anaesthetic during a Caesarean section helps manage pain after the operation and can reduce consumption of painkillers, according to Cochrane Researchers. The researchers recommend local anaesthetics as part of integrated pain management strategies for Caesarean section operations, provided that consideration is given to the cost.“This review is particularly important in light of the growing number of women giving birth by Caesarean section,” says lead researcher, Anthony...
