A recent study by University of Illinois researcher Sheldon H. Jacobson found a strong correlation between the rise in automobile usage and obesity rates in the US. By analyzing data from 1985 to 2007, Jacobson discovered that vehicle use is directly linked to sedentary behavior, which ultimately contributes to obesity.
Advances in technology have reduced sequencing gene costs to $1,000, but analyzing genomic data for personalized medicine remains costly. New trends in bioinformatics, such as commercial drug discovery and collaboration, are helping reduce the burden.
A recent study analyzing data from 6,400 low-income immigrant children in Montreal reveals that their BMI drops significantly as they grow up in Canada. The 'healthy immigrant effect' seen in adult immigrants is lost in successive generations of children.

A study of Medicare beneficiaries found that the length of hospital stay after hip replacement surgery decreased over time, while the proportion of patients discharged home declined and those sent to skilled care facilities increased. Readmission rates also rose after hip replacement surgery.
A recent study published in Archives of Surgery found that patients with do-not-resuscitate (DNR) orders have a higher risk of poor surgical outcomes, including increased mortality rates and complication rates. The study analyzed data from over 120 hospitals and found that nearly a quarter of DNR patients died within 30 days of surgery.

A large-scale Harvard study of over 51,000 men and 121,700 women found no association between mercury exposure and increased risk of coronary heart disease or stroke. Higher levels of mercury exposure were actually linked to lower cardiovascular disease risk, likely due to beneficial effects of fish consumption.

A study published in CMAJ found that nonmilitary personnel in Iraq and Afghanistan were more likely to be medically evacuated with non-war-related injuries, returning to duty after such injuries. Military personnel, however, were more likely to be evacuated for war-related injuries.
A study by Johns Hopkins Medicine found that civilians with noncombat injuries are more likely to be evacuated for treatment, but also more likely to return to work in war zones due to higher salaries. In contrast, soldiers are less motivated to return after such injuries, possibly due to the loss of hazardous duty pay.

A new study found that female executives are more likely to leave their jobs voluntarily and involuntarily than their male counterparts. Women account for 7.2% of departures, compared to 3.8% for men, with higher voluntary rates (4.3% vs 2.8%) and involuntary rates (2.9% vs 0.9%). The study suggests that women may leave due to domestic...
A new study from the University of Toronto suggests that having more schedule control at work can lead to blurring of boundaries between work and family life. Researchers found that individuals with partial or full schedule control experienced less negative consequences in terms of work-family multitasking activities.

A meta-analysis of previous research reveals that very low-birth-weight and very preterm infants have a higher likelihood of neonatal and predischarge death when born at less-specialized hospitals. The study found a significant increase in mortality rates for these high-risk infants, emphasizing the importance of hospital level of care.
Researchers found that spouses tend to pick each other based on shared personality traits rather than growing alike over time. Aggression is an exception to this pattern, where spouses may become more aggressive together due to their interactions.
