Aging is a global health challenge that is associated with a decline in cognitive function. In the United States, most older adults (≥50 years) do not meet the recommended daily fiber intake, although preliminary evidence suggests that dietary fiber consumption could elicit clinical benefits on cognitive function. We investigated the associations between dietary fiber intake and cognitive function in older adults. ⋯ Higher dietary fiber intake is associated with improved specific components of cognitive function in older adults aged 60 years and older. Public health interventions that target a recommended dietary fiber intake may provide a promising strategy to combat cognitive decline in high-risk groups of older adults.

Anemia is common in older individuals, but it is not known whether the prognostic impact of transfusion differs according to cardiac troponin concentration. ⋯ This pilot study suggests that transfusion could be associated with better 30-day outcomes in older anemic patients with anemia-related myocardial injury. Thus, troponin levels could be involved in decision-making relative to transfusion in anemic older patients. Clinical trials are needed to establish the benefit of transfusion in patients with elevated troponins.

Clinical characteristics of patients with acute myocardial infarction after gastrointestinal bleeding are poorly characterized. We sought to evaluate the incidence, management and outcomes of myocardial infarction following hospitalization for gastrointestinal bleeding. ⋯ In the first 3 months after hospitalization for gastrointestinal bleeding, 1 of every 83 patients was readmitted with acute myocardial infarction. Patients with myocardial infarction after gastrointestinal bleeding were less likely to undergo invasive management and coronary revascularization and had higher mortality than those without recent bleeding.
