A new study published in The Lancet HIV indicates that HIV-2 is more pathogenic than previously demonstrated, with a slower but identical progression to AIDS as HIV-1. Early treatment is recommended for all patients with HIV-2, despite current WHO guidelines only offering treatment to those with HIV-1.
A systematic review and meta-analysis of 19 studies found that people with the highest anthocyanin intake were 9% less likely to suffer from coronary heart disease. Anthocyanins have also been linked to improved risk factors for heart disease, such as cholesterol levels and blood pressure.
A study by Penn State found that adults who sleep six hours per night have significantly more concentrated urine and higher odds of dehydration compared to those who sleep eight hours. This is due to the body's hormonal system regulating hydration, particularly the hormone vasopressin.

The study, led by the Barcelona Institute for Global Health, analyzed data from over 4,500 people and found that physical activity benefits even in areas with high air pollution.
A new study published in The BMJ suggests that genetics play a significantly larger role in the development of high serum urate levels than diet. Despite long-held assumptions about diet's impact on gout, researchers found that only a small percentage of variation in urate levels could be explained by food choices.
Research from the University of Bath and London School of Economics found that business owners with above-average optimism earned 30% less than those with below-average optimism. Pessimistic entrepreneurs are more likely to avoid poor entrepreneurial projects, while optimistic ones may be misled into setting up failing businesses.
