(1) Moderate hypertension linked to brain damage. Physcians think about the burden of hypertension on the heart and the kidney, not on the brain.
Dr. White et al enrolled 72 people aged 75-89 who underwent blood pressure, cognitive, mobility and MRI brain assessments at entry and 24 months later. The amount of white matter hyperintensity was the marker of brain damage.
The top and buttom tertiles had average systolic pressures of 144 and 117 mmHg. The top tertile showed a significantly larger increase in brain damage over the 2 years of follow up, a siginificantly longer 8-foot walk time, a significantly slwoer walking speed and nonsignificant trend toward poorer results on cognition tests.

(2) Exercise Can Reduce Colon Polyps by One-Third. In a prospective study of multiple ethnic groups, people with at least one hour of moderate physical activity per week had a one-third lower risk of colon polyps, reports Dr. Nelson Sanchez at Sloan-Kettering Cancer Center, New York. Of the 982 middle-aged adults who enrolled in the study, 558(57%) were Hispanic, 202(21%) were Asian, 149(15%) were black, 69(7%) were white.
The polyps were identified during screening colonoscopy. About half of the participants(513 or 52%)reported that they exercise for at least 1 hour per week, and the median duration of this activity levels was 5 years. The overall prevalence of colon polyps was 29.5%. The prevalence was significantly higher among patients who reported not exercising for 1 hour or more: 33.2% vs 25.3%, respectively.
