High-priced cigarettes ($4.50+ per pack) and smoke-free homes are associated with lower smoking behaviors in low-income individuals, who tend to smoke more due to lower state cigarette prices. A smoke-free home is also crucial for successful quitting among these smokers.
A new study by American College of Surgeons found that appendectomy patients who undergo surgery on weekends do not experience more postoperative complications compared to weekday patients. However, they pay $419 more in hospital charges on average. The study analyzed nearly 826,000 appendectomies performed between 2006 and 2009.
A Finnish population-based study with over 4,000 participants found that eating five meals a day reduces the risk of obesity in adolescents. Skipping breakfast, on the other hand, is associated with greater BMI and waist circumference. Maternal weight gain during pregnancy also increases the risk of obesity in offspring.
A systematic review of six studies involving over 900,000 patients found a positive association between severe hypoglycaemia and cardiovascular disease risk. The link was consistent across all studies, suggesting that avoiding severe hypoglycaemia may be crucial to preventing CVD in type 2 diabetics.
A large clinical study found no evidence that THC slows progressive multiple sclerosis (MS) progression. However, participants at the lower end of the disability scale showed some benefits. The study suggests that further research is needed to confirm these findings.
A study of 601 women with breast cancer found that African-American women were more likely to experience delay in treatment due to type of treatment received or younger age. White women experienced delay if they underwent immediate breast reconstruction following mastectomy.

The study aims to investigate chronic diseases and risk factors in this population.
A study published in CMAJ found that 13.5% of Canadian Forces personnel who served in support of the Afghanistan mission between 2001-08 had a mental health disorder related to their deployment. The most common disorders were posttraumatic stress disorder (PTSD) and depression, with PTSD being found in 8% of personnel.
A Stanford-led study found that men diagnosed with azoospermia have a significantly higher risk of developing cancer than the general population. The study, which analyzed data from over 2,200 infertile men, found that azoospermic men were nearly three times more likely to receive a cancer diagnosis than non-azoospermic men.

A study published in Archives of Neurology found a strong association between poor physical performance and increased dementia risk in individuals aged 90 and older. The study revealed that even modest declines in physical performance were associated with higher dementia odds, particularly gait slowing and grip strength.
A large-scale study found that people with mental health problems have a lower life expectancy due to increased risks of cardiovascular disease and cancer. Even minor symptoms of anxiety or depression are associated with higher mortality rates.
A recent Genographic Project study has shown that individuals with the Romanian 'Basarab' surname may not be direct biological descendants of the Basarab dynasty, which ruled Wallachia from 1330-1601. The research found genetic diversity among modern-day Basarab men, suggesting a polyphyletic name with multiple unrelated male founders.

A team of Indiana University researchers has discovered that promiscuous female birds have higher reproductive success due to a genetic 'trade-up', resulting in more offspring. By studying dark-eyed juncos, the study found that females who mate outside their social pair have twice as many grandchildren than those who remain truly monog...
Results from CREDO-Kyoto registry show CABG associated with lower risk for serious adverse events in patients with triple vessel disease. Higher risk of MI and all-cause death found with PCI, particularly in those with high SYNTAX scores.
The RESET trial demonstrates that sirolimus-eluting stents are non-inferior to everolimus-eluting stents in terms of target-lesion revascularisation rate and late lumen loss. However, the study's findings may be influenced by the relatively low-risk patient population.
Research at Queen's University Biological Station reveals that singing shared songs is an attention-seeking behavior often displayed by older males. Song sharing is linked to individual differences like age and neighborhood characteristics.
Researchers have identified a gene variant associated with the onset of chronic obstructive pulmonary disease (COPD) in Caucasian men. The study found that variants in the vitamin D receptor gene influence the time to development of COPD, highlighting the potential role of vitamin D metabolic pathways in COPD risk.
A Spanish-Mexican research team found that wild birds exhibit ageing in terms of reproductive capacity and DNA damage. As males age, their germline becomes damaged, increasing the risk of genetic illnesses in their offspring.
A large population-based study found that even mild stress can lead to long-term disability and an inability to work. Higher levels of stress at the start of the study were associated with a significantly greater likelihood of receiving disability benefits, with up to 70% more likely for those with mild stress.
Researchers from Kansas State University discovered that people's enjoyment of movies depends on both the content and their co-viewer. The study found that graphic sex scenes in particular cause discomfort for parents and teens, leading to awkward interactions.
