Two large studies found a link between high consumption of ultra-processed foods and increased risks of cardiovascular disease, bowel cancer, and death. The findings support policies limiting ultra-processed foods and promote eating unprocessed or minimally-processed foods for improved public health.
A recent investigation by The BMJ reveals that hospital trusts in England are bracing for a significant increase in energy bills this winter, with some anticipating a rise of over 200% in fuel costs. This would result in reduced patient care and staffing levels, posing a major challenge to the NHS's ability to operate effectively.
A large study found associations between steroid use and structural changes in brain white and grey matter, which may explain neuropsychiatric side effects. Steroid use was associated with reduced white matter structure and altered brain structures involved in cognitive and emotional processing.
Despite progress in women's participation and equal pay, sexist scheduling of major mixed-sex sporting fixtures perpetuates unequal opportunities for female athletes. Experts call for a rethink to enable women and girls to realize their full potential on and off the sports field.
Researchers found a lower concussion rate in Florida, where headgear was mandated, compared to states without. The rate was 0.39 concussions/1000 athlete exposures with mandatory headgear, vs 0.44 without. This suggests that headgear may be worth considering for high schools and other levels of play.
