Cholera vaccine supply set to double, easing global shortage

The global supply of oral cholera vaccines is set to double after WHO approved a third producer, helping to address global shortages and expand access in more countries. Globally, OCV production is low, with demands currently exceeding supply. Sudan and Haiti last year made requests to WHO for supplies of vaccines to conduct pre-emptive vaccination campaigns that could not be filled because of the global shortage. The vaccine producer, a South Korean company, is the latest oral cholera vaccine (OCV) manufacturer to be approved under the WHO’s pre-qualification programme, which…

High-Dose Vitamin D Supplementation Ups Elderly Fall Risk

High-dose vitamin D supplementation does not improve lower-extremity function and increases the risk for falls among elderly adults, a new study finds. The results were published online January 4 in JAMA Internal Medicine by Heike A Bischoff-Ferrari, MD, DrPH, chair of the department of geriatrics and aging research at the University Hospital of Zurich, Switzerland, and colleagues. In the randomized clinical trial of 200 men and women aged 70 or older who had experienced at least one low-trauma fall in the prior year, two high vitamin D doses monthly were…

Herbal food supplement labels ‘can be misleading’

    Some herbal food supplements do not contain what they claim on the label, a study has found. The BBC health series ‘Trust Me, I’m a Doctor’ teamed up with experts from University College London to test a selection of products bought from high street shops or online retailers. Of 30 ginkgo products tested, eight contained little or no ginkgo extract. In one case of milk thistle, unidentified substances were present in place of milk thistle. All the evening primrose products performed well. The UCL team tested around 70…

‘Softener’ may help kill cancers

    It may be possible to “soften-up” cancers before hitting them with chemotherapy drugs, researchers suggest. A study, published in the Cancer Cell, uncovered how tumours can become resistant to commonly used drugs. The University of Manchester team suggest drugs already in development may be able to counter this resistance to make chemotherapy more effective. The approach has not yet been tested in people. The team were looking at a class of drugs called taxanes, which are used to treat a range of cancers including breast and ovarian. The…

Dietary supplements linked to increased cancer risk

Consumers are always looking for ways to minimize their cancer risk, which is one reason why many turn to over-the-counter vitamin and mineral supplements. But new research finds that while companies promote dietary supplements for their cancer-prevention benefit, some may end up doing more harm than good. Dr. Tim Byers, director for cancer prevention and control at the University of Colorado Cancer Center, conducted a meta-analysis of two decades worth of research — 12 trials that involved more than 300,000 people — and found a number of supplements actually made a person much more…

Tests of Cholesterol Drugs Offer Hope of Reducing Heart Attacks and Strokes

A new class of experimental cholesterol drugs might sharply reduce the risk of heart attacks and strokes, researchers reported on Sunday, citing what they described as preliminary evidence. The drugs, one being developed by Amgen and the other by Sanofi andRegeneron Pharmaceuticals, are already known to sharply reduce so-called bad cholesterol, sometimes to levels lower than those achieved by statins like Lipitor, the mainstay lipid-lowering medicines. What has not been known, however, is whether the drugs do what patients and doctors really care about: protect against heart attacks, strokes and other cardiovascular problems or “events.” The early…

HIV drugs ‘boost South African life expectancy’

Life expectancy in South Africa has increased dramatically over the last decade, mainly thanks to life-saving Aids drugs, a government report says. South Africans are living on average up to 61.2 years compared to 52.2 years nearly 10 years ago, the figures show. “The life expectancy is expected to keep improving because of improving medical science methods,” the head of the national statistics agency said. South Africa runs the world’s largest anti-retroviral (ARV) drugs programme. “For 2014, life expectancy at birth is estimated at 59.1 years for males and 63.1…
