Question: To determine the associations between serum cortisol and HDL cholesterol, other lipoprotein lipids and cardiovascular risk factors, carotid atherosclerosis, and clinical heart disease in older people.', 'A cross-sectional, observational, ancillary study of the Cardiovascular Health Study (CHS).', 'A total of 245 community-dwelling people, 65 to 89 years old, were recruited consecutively for a 2-month period from the CHS cohort in Forsyth County, North Carolina.', 'Cortisol was measured by radioimmunoassay in serum collected between 7:00 and 10:00 AM after an overnight fast. Cortisol levels were correlated with lipoprotein lipids, insulin, glucose, body mass index, waist-hip ratio, prevalent coronary heart disease, hypertension, diabetes, and carotid atherosclerosis by B-mode ultrasound.', 'Serum cortisol was correlated negatively (r = -.24) with body mass index and waist-hip ratio (r = -.16) but was not related significantly to fasting insulin or glucose. Cortisol was not associated significantly with triglyceride and low density lipoprotein cholesterol but showed a positive correlation (r = .21) with high density lipoprotein cholesterol. The relationship between cortisol and high density lipoprotein cholesterol persisted after adjustment for gender, body mass index, waist-hip ratio, cigarette and alcohol use, triglyceride level, and diabetes. There was a trend toward a negative correlation between cortisol and measures of carotid atherosclerosis, but no significant relationship was indicated between cortisol and prevalent coronary heart disease, hypertension, or diabetes.

Question: We aimed to investigate structural abnormalities in first-episode remitted geriatric depression (RGD) with optimized voxel-based morphometry (VBM) in closely matched patients and healthy control subjects and examine the relationship of performances on neuropsychological tests with regional gray matter volumes.', 'Nineteen subjects with first-episode RGD and 16 well-matched healthy control subjects were recruited for this study, and neuropsychological tests and magnetic resonance imaging were conducted on the subjects. The differences in regional gray matter volume were determined between these two groups by optimized VBM.', 'The volumes of right superior frontal cortex, left postcentral cortex, and right middle temporal gyrus were significantly smaller in patients with RGD relative to healthy control subjects. However, patients with RGD had larger left cingulate gyrus volume compared with healthy control subjects. There was a significant negative correlation between left cingulate gyrus volume and Rey Auditory Verbal Learning Test delayed recall raw score in patients with RGD.

Question: The parenteral administration of oestradiol acutely protects against exercise-induced myocardial ischaemia in women, but whether this effect is sex-specific is not known.', 'The effects of acutely administered conjugated equine oestrogen on exercise-induced myocardial ischaemia in men with established coronary heart disease were investigated in a randomized, placebo-controlled, double-blind cross-over trial.', 'Twenty men, aged 62 +/- 11.6 years, with reproducible exercise-induced myocardial ischaemia were treated with either intravenous conjugated equine oestrogen (25 mg) or saline prior to undergoing an exercise stress test. Primary end-points were total exercise time and time to 1 mm ST-segment depression.', 'All participants completed the protocol. Total exercise time exceeded the baseline value in 17 of the 20 men following saline, and in 17 of the 20 men following oestrogen pretreatment. Time to 1 mm ST-segment depression exceeded the baseline value in 14 of the 19 men following saline, and following oestrogen administration, exceeded baseline in 13 of the 19 men. There was no significant difference between the two treatments in either time to 1 mm ST-segment depression or total exercise time. A period effect was apparent for total exercise time (P = 0.05) but not for time to ST-segment depression.
