A new study from the UK suggests that low levels of the 'good' HDL cholesterol is linked to poor memory, and decline in memory, in middle aged adults. The study is the work of researchers at University College, London, and is published in the 30th June issue of the Arteriosclerosis, Thrombosis and Vascular Biology journal of the American Heart Association.

Women over age 90 are significantly more likely to have dementia compared to men in their 90s, according to a study published in the July 2, 2008, online issue of Neurology®, the medical journal of the American Academy of Neurology. Research shows that dementia risk for both men and women increases from age 65 to 85, but this most recent study is one of few that looks at people over age 90.

Black women taking low-dose oral contraceptives have a risk of side effects that can lead to heart disease and diabetes, according to a study published in the Journal of Clinical Endocrinology, Reuters health reports. For the study, NIH researcher Anne Summer and colleagues examined 104 healthy black women who did not have diabetes. Twenty-one of the women were taking oral contraceptives and 83 were not.read more

IntroductionA number of breast cancer risk prediction models have been developed to provide insight into a woman's individual breast cancer risk. Although circulating levels of estradiol in postmenopausal women predict subsequent breast cancer risk, whether the addition of estradiol levels adds significantly to a model's predictive power has not previously been evaluated.Methods:Using linear regression, the authors developed an imputed estradiol score using measured estradiol levels (the outcome) and both case status and risk factor data (e.g., body mass index) from a nested case-control study conducted within a large prospective cohort study and used multiple imputation methods to develop an overall risk model including both risk factor data from the main cohort and estradiol levels from the nested case-control study.Results:The authors evaluated the addition of imputed estradiol level to the previously published Rosner and Colditz log incidence model for breast cancer risk predi

Measuring calcium deposits in the heart's arteries can help predict overall death risk in American adults, even when they are elderly, according to a new study published in the July issue of Journal of the American College of Cardiology. Matthew J. Budoff, M.D.
