The widely used antidepressant paroxetine is neither safe nor effective for adolescents with depression, concludes a reanalysis of an influential study originally published in 2001. The new results, published by The BMJ today, contradict the original research findings that portrayed paroxetine as an effective and safe treatment for children and adolescents with major depression.

A gap in scientific knowledge about a family of drugs that are used to treat Type 2 diabetes has been highlighted in a new study. Researchers behind the study say that while their results are speculative at this stage, they point to a lack of complete information about the potential impact of a group of treatments known as GLP-1 agonists, or incretin mimetics.

Research has found evidence that spending time in nature provides protections against a startling range of diseases, including depression, diabetes, obesity, ADHD, cardiovascular disease, cancer, and many more. How this exposure to green space leads to better health has remained a mystery.

Two recently published studies in the journals Age and the British Journal of Nutrition (BJN) demonstrate that consuming cocoa flavanols improves cardiovascular function and lessens the burden on the heart that comes with the ageing and stiffening of arteries. The studies also provide novel data to indicate that intake of cocoa flavanols reduces the risk of developing cardiovascular disease (CVD).

Societies are failing women, children and adolescents, particularly in the poorest communities around the world, and urgent action is needed to save lives and improve health, say global health experts.

Eating a Mediterranean diet supplemented with extra virgin olive oil was associated with a relatively lower risk of breast cancer in a study of women in Spain, according to an article published online by JAMA Internal Medicine. Breast cancer is a frequently diagnosed cancer and a leading cause of death in women.

Capsaicin, the compound responsible for chilis' heat, is used in creams sold to relieve pain, and recent research shows that in high doses, it kills prostate cancer cells. Now researchers are finding clues that help explain how the substance works. Their conclusions suggest that one day it could come in a new, therapeutic form.
