Long commutes unhealthy

Long commutes to work, particularly more than 10 miles, may be hazardous for health. These are associated with increased weight, bigger waistlines and poorer heart and lung fitness. Researchers at Washington University in St Louis, Missouri, who studied nearly 4,300 commuters, found that people, who travelled 10 miles to work, were more likely to have high blood pressure and workers commuting 15 miles had a greater risk of being obese and not getting enough exercise.

Probiotics may prevent diarrhoea

Taking probiotics on top of a course of antibiotics may help ward off the diarrhoea that often comes along with antibiotic treatment, a new review of past studies suggests. When researchers combined trials of all types of the gut-healthy microbes, they found that patients with a range of conditions —from ear infections to sepsis — were 42 per cent less likely to get diarrhoea from their antibiotic drugs if they were also taking probiotics.

Tablet may help reduce HIV risk

Gilead Sciences Inc’s Truvada tablets appear safe and effective for reducing the risk of HIV infection, US regulators have said. But they recommended a cautious approach for using the drug in efforts to prevent the virus that causes AIDS. Food and Drug Administration staff said Truvada, which is already being used by patients with the human immunodeficiency virus, is well tolerated overall by uninfected people and may prevent infection in high-risk individuals when used in combination with other strategies. — Reuters
