A new NYU study found that teen alcohol consumption is linked to unsafe driving and compromised relationships with peers, while marijuana consumption compromises relationships with authority figures. Marijuana use also leads to lower school or job performance and increased regret.
A randomized controlled trial found that melatonin supplementation had no effect on reducing delirium in elderly patients undergoing hip fracture surgery. The study suggests that melatonin may not be effective in preventing postoperative delirium, and further research is needed to compare its effects with antipsychotics.
Researchers found that macrophages from the lungs of old mice had different responses to infections than those of young mice, but these changes were reversed by ibuprofen. The study suggests that reducing inflammation with diet, exercise, and/or drugs may help prevent or reduce diseases in the elderly.
The HARVEST study found that coffee drinking increased the risk of prediabetes in patients with hypertension, particularly those who were slow caffeine metabolisers and overweight or obese. Moderate coffee consumption also heightened this risk, whereas heavy coffee drinkers only saw an increased risk if they were slow metabolizers.

The intervention was also associated with fewer serious adverse events compared to traditional bariatric surgery.
Researchers at Johns Hopkins Medicine discover that tumor cells can spread through lymphatic vessels by releasing signaling molecules, which attract and facilitate the growth of new blood vessels. The HIV drug maraviroc blocks these signals, preventing breast cancer metastasis when combined with a VEGF-blocking drug.
A team of researchers has developed a mathematical model for epigenetic silencing, which reveals how DNA sequences are silenced in cancer cells. The model explains how histone and DNA methylation work together to regulate gene expression, and could lead to new strategies for preventing cancer development.

Researchers found that countries with strict dog quarantine policies had lower rates of the disease, which is spread by living cancer cells between dogs during sex.
Researchers at Kansas State University have discovered a family of proteins in Staphylococcus aureus that prevent neutrophils from functioning, leading to potential new treatments for staph infections and inflammatory diseases such as emphysema. The study sheds light on how the bacteria evade the immune system.
A new study found that primary seatbelt laws increase seatbelt usage, mitigating the drop in seatbelt use associated with increasing obesity rates. Seatbelt laws can help prevent automobile fatalities by reducing the risk of injury or death in car accidents.
A nationwide Danish register study found that psychiatrically ill youth exposed to antipsychotic medications had a significantly higher risk of developing type II diabetes compared to those not exposed. Regular cardiometabolic monitoring should be integral part of antipsychotic prescribing in children and adolescents.
Researchers found that wearing a hijab buffers against negative body image among British Muslim women, reducing reliance on media beauty standards and emphasis on appearance. The study suggests the hijab helps some women reject prescriptive beauty ideals.
A study found a substantial increase in double mastectomy use among California women with early-stage breast cancer between 1998 and 2011. Despite the procedure's lack of association with lower mortality rates compared to breast-conserving surgery plus radiation, its higher risk of death was noted.
A meta-analysis of nearly 50 trials involving over 7,300 individuals found that low-carbohydrate or low-fat diets resulted in significant weight loss, with minimal differences between individual diet programs. The study suggests that patients can choose a diet that suits their needs and preferences for optimal weight loss.
Heart failure affects millions worldwide, yet awareness is low among politicians, healthcare professionals, and the public. Many cases are preventable and treatable, improving quality of life and survival.
Recent research highlights the impact of gastrointestinal symptoms on medication absorption and availability in autism patients. Alternative modes of drug administration are needed to provide more effective therapy.
A new study reveals that modest reductions in nutrient pollution led to long-term improvements in water clarity, allowing underwater grasses to thrive. The plants' rapid growth was fueled by positive feedback loops, where they improved their own growing conditions and resisted disturbances.
A new study found lower testosterone levels in men with sudden cardiac arrest and higher estradiol levels in both men and women were associated with increased risk. The research suggests that hormone levels may play a role in predicting patients' likelihood of suffering from the usually fatal condition.
Researchers have engineered E. coli bacteria to generate renewable propane, providing a potential alternative to fossil fuels. The production of propane is achieved through the use of specific enzymes that convert fatty acids into hydrocarbons.
Despite having a family history of CVD, individuals are unlikely to adopt healthier habits, with those reporting a family history showing higher heart ages and poorer diet scores. Small lifestyle changes can still significantly reduce CVD risk, suggesting alternative strategies for behavior change.
Researchers found that short-distance migratory birds increase their flight speed in spring to reach breeding grounds first and secure resources. In contrast, long-distance migrants take a more leisurely pace in autumn as they are not under the same time pressure.
A recent study found that up to 20% of medical students reported mistreatment, including public humiliation, during their clinical education. Only 31% of those who experienced mistreatment reported it to administrators.
