The researchers analyzed data from over 4 million deliveries and found that women with sleep apnea were more likely to develop these conditions, particularly when their weight was taken into account.
Researchers measured pollutants from secondhand smoke near bars and restaurants with indoor smoking bans, finding a rise in pollutants associated with an increase in smokers. The study suggests that secondhand smoke is present in these outdoor zones, potentially creating unhealthy environments for non-smokers.
A new study of 914 children with mild to moderate asthma found that consistent inhaled steroid use was associated with a 20% lower likelihood of well-controlled asthma. The study suggests genetic factors may play a role in non-response to steroids, highlighting the need for personalized treatment approaches.

Certain environmental factors such as older home conditions and carpeting increase endotoxin levels, while genetic predisposition may also play a role.
A survey of high school students found that most struggle with early morning start times, leading to decreased alertness and poor academic performance. The teens recommended starting school at a later time, allowing for more sleep and improved focus.
A new study found that a two-step sedation and ventilator weaning protocol, called 'wake up and breathe,' allows patients to come off the ventilator faster. This results in reduced ICU stays and improved patient outcomes.
