Randomized Controlled TrialExercise and vitamin D in fall prevention among older women: a randomized clinical trial.
While vitamin D supplementation and exercise are recommended for prevention of falls for older people, results regarding these 2 factors are contradictory. ⋯ The rate of injurious falls and injured fallers more than halved with strength and balance training in home-dwelling older women, while neither exercise nor vitamin D affected the rate of falls. Exercise improved physical functioning. Future research is needed to determine the role of vitamin D in the enhancement of strength, balance, and mobility.

Prospective evaluation of the association of nut/peanut consumption with total and cause-specific mortality.
High intake of nuts has been linked to a reduced risk of mortality. Previous studies, however, were primarily conducted among people of European descent, particularly those of high socioeconomic status. ⋯ Nut consumption was associated with decreased overall and cardiovascular disease mortality across different ethnic groups and among individuals from low SES groups. Consumption of nuts, particularly peanuts given their general affordability, may be considered a cost-effective measure to improve cardiovascular health.

Perioperative cardiovascular care for patients undergoing noncardiac surgical intervention.
The field of perioperative medicine has garnered legitimacy during the past 3 decades. Adverse cardiovascular events in the perioperative period account for significant morbidity and mortality. Although testing patients preoperatively to detect ischemia and identify those who may benefit from modifications in care is a tempting strategy, risk assessment should account for posterior probability. ⋯ There has been enthusiasm for medical therapies that may reduce the risk of adverse cardiovascular events in the perioperative period. Current guidelines encourage the perioperative use of β-blockade in patients already receiving such therapy and caution against initiating such therapy on the day of the surgical procedure. Reduction of morbidity and mortality in the perioperative period relies on an understanding of the myriad physiological perturbations in this period and thoughtful selection of patients for further testing and treatment.
