A study published in The Lancet Respiratory Medicine found that smokers who metabolize nicotine quickly have better quit rates with varenicline, a non-nicotine replacement therapy drug. In contrast, slow metabolizers have similar success with the nicotine patch but without side effects.
A study published in Diabetologia found that black women working night shifts are more likely to develop diabetes than those who never work at night. The study revealed a stronger association in younger women, with increased risks of up to 39% after 10 or more years of night shift work.
Across Australia, severe winter temperatures are a bigger risk to health than sweltering summer heat. Death rates in cities like Brisbane were up to 30% higher in winter than summer. The study found that Australians may be more vulnerable to cold weather due to lack of preparation and focus on public health campaigns.
