Factors Associated With Cardiac Rehabilitation Participation in Older Adults After Myocardial Infarction: THE SILVER-AMI STUDY.

Purpose: Cardiac rehabilitation (CR) is a key aspect of secondary prevention following acute myocardial infarction (AMI). While there is growing evidence of unique benefits of CR in older adults, it remains underutilized. We aimed to examine specific demographic, clinical, and functional factors associated with utilization of CR among older adults hospitalized with AMI.

Falls in older adults after hospitalization for acute myocardial infarction.

Background: After hospitalization for acute myocardial infarction (AMI), older adults may be at increased risk for falls due to deconditioning, new medications, and worsening health status. Our primary objective was to identify risk factors for falls after AMI hospitalization among adults over age 75.

Methods: We used data from the Comprehensive Evaluation of Risk Factors in Older Patients with AMI (SILVER-AMI) study, a prospective cohort study of 3041 adults age 75 and older hospitalized with AMI at 94 community and academic medical centers across the United States.

Dose-Response Relationships Between Gonadal Steroids and Bone, Body Composition, and Sexual Function in Aging Men.

Context: Most labs set the lower limit of normal for testosterone at the 2.5th percentile of values in young or age-matched men, an approach that does not consider the physiologic changes associated with various testosterone concentrations.

Objective: To characterize the dose-response relationships between gonadal steroid concentrations and measures regulated by gonadal steroids in older men.

Gonadal steroid-dependent effects on bone turnover and bone mineral density in men.

Background: Severe gonadal steroid deficiency induces bone loss in adult men; however, the specific roles of androgen and estrogen deficiency in hypogonadal bone loss are unclear. Additionally, the threshold levels of testosterone and estradiol that initiate bone loss are uncertain.

Methods: One hundred ninety-eight healthy men, ages 20-50, received goserelin acetate, which suppresses endogenous gonadal steroid production, and were randomized to treatment with 0, 1.

Measurement of perihematomal edema in intracerebral hemorrhage.

Background And Purpose: Perihematomal edema (PHE) is a marker of secondary injury in intracerebral hemorrhage (ICH). PHE measurement on computed tomography (CT) is challenging, and the principles used to detect PHE have not been described fully. We developed a systematic approach for CT-based measurement of PHE.

Angiographic management of pseudoaneurysm and arteriocalyceal fistula following blunt trauma: case report and review of the literature.

We report a case of blunt trauma causing both a pseudoaneurysm and an arteriocalyceal fistula. These 2 lesions have not previously been reported occurring simultaneously as a complication of renal trauma. Pathophysiology, clinical presentation, and management options are discussed.
