Insulin effects on the left ventricle in older hypertensive subjects

Article Abstract:

Hyperinsulinemia appears to be associated with increased left ventricular (LV) mass and with better systolic performance in older hypertensive subjects. Insulin effects on the left ventricle have been studied in Italy in 37 hypertensive subjects aged 50-80, 17 of whom were men. Divided into two groups based on the median value of a 2-hr post-loading plasma insulin, no difference was found in blood pressure level. Hyperinsulinemic hypertensive subjects, however, had greater LV mass, interventricular septum thickness and mean wall thickness and better systolic function-ejection and shortening fractions.

Home visits by an occupational therapist for assessment and modification of environmental hazards: a randomized trial of falls prevention

Article Abstract:

Home visits by an occupational therapist for assessment/modification of environmental hazards have been investigated in a randomized controlled trial. Falls prevention was investigated. It was found that home visits by such therapists could prevent falls among older persons at increased risk of falling, but the effect might not be from home modifications only. Changes in behavior may enable older pole to live more safely as a result of the visits.
