Effects of Traditional vs. iPad-Enhanced Aerobic Exercise on Wayfinding Efficacy and Cognition: A Pilot Randomized Controlled Trial.

The purpose of this pilot study was to test the feasibility and efficacy of an iPad-enhanced aerobic exercise intervention designed to enhance wayfinding efficacy and performance and relevant cognitive functioning among middle-aged adults at risk for cognitive impairment. Twenty-seven low active adults (21 females) aged 45 to 62 years (51.22 ± 5.

Cognitive function in hypertensives treated with atenolol or propranolol.

Study Objective: To test reports that beta blockers, particularly lipophilic forms, impair cognitive function and cause psychiatric disturbances.

Design: Randomized, double-blind, controlled crossover trial with eight-week treatment periods.

Patients: Sequential sample of 42 male veterans, with untreated diastolic blood pressures (DBP) between 90 and 110 mmHg, aged 35-64 years.

Physical examination: a revered skill under scrutiny.

Clinicians in the 1980s rely on the physical examination to a lesser degree than their predecessors in making diagnostic and therapeutic decisions. The major criticisms are that the physical examination lacks sensitivity for many common diseases and has not been subjected to the same scientific scrutiny afforded laboratory testing. On the positive side, the physical examination is a series of diagnostic maneuvers that permit physicians to test hypotheses generated during history taking, to determine disease severity, and to lessen clinical uncertainty.
