Professional American-style football players are among the largest athletes across contemporary sporting disciplines. Weight gain during football participation is common, but the health implications of this early-life weight gain remain incompletely understood. We sought to define weight trajectories of former professional American-style football athletes and to establish their relationship with 5 common health afflictions (cardiovascular disease, cardiometabolic disease, neurocognitive impairment, sleep apnea, and chronic pain). ⋯ Early-life weight gain among American-style football athletes is common and is associated with risk of adverse health profiles during later-life. These findings establish football-associated weight gain as a key predictor of post-career health and raise important questions about the central role of targeted weight gain in this population.

The measurement of D-dimer can provide useful information to aid in the diagnosis of patients with suspected venous thromboembolism. D-dimer measurement in conjunction with adequate estimation of pretest probability can facilitate the safe discharge of patients with suspected pulmonary embolism and limit unnecessary investigation or anticoagulation. We review clinical decision-making strategies in the diagnosis of pulmonary embolism and propose means to minimize diagnostic error that might arise from knowledge of the D-dimer result prior to clinical assessment.

Drinking coffee can raise public health problems, but the association between coffee and kidney disease is unknown. We studied whether coffee intake can affect the development of chronic kidney disease in the general population. ⋯ Our findings suggest that daily coffee intake is associated with decreased risk of the development of chronic kidney disease.

Dementia and Atrial Fibrillation: Pathophysiological Mechanisms and Therapeutic Implications.
Atrial fibrillation increases the risk of stroke by a factor of four- to fivefold, and dementia is a common consequence of stroke. However, atrial fibrillation has been associated with cognitive impairment and dementia, even in patients without prior overt stroke. Nonischemic mechanisms include cerebral hypoperfusion, vascular inflammation, brain atrophy, genetic factors, and shared risk factors such as age or hypertension. ⋯ Overall, the pathogenesis linking atrial fibrillation to dementia is likely multifactorial. Cerebral infarctions, including silent stroke, play a central role. These findings underscore the importance of stroke prevention measures in atrial fibrillation patients.
