High rates of undiagnosed vascular cognitive impairment among American Indian veterans.

As data on prevalence and etiology of dementia in American Indians are limited, we sought to determine rates and patterns of memory loss among American Indian veterans with vascular risk factors. Sixty consecutive outpatient American Indian veterans with a mean age of 64 years (range 50-86), without prior dementia or mild cognitive impairment (MCI), and with ≥ 2 vascular risk factors were enrolled. The Montreal Cognitive Assessment (MoCA) and the Beck Depression Inventory-II were used to screen for cognitive impairment and depression.

Reduced high-density lipoprotein level is linked to worse ankle brachial index and peak oxygen uptake in postmenopausal women with peripheral arterial disease.

Women with peripheral arterial disease (PAD) have more limited physical function than men but the mechanisms involved are not clear. We determined whether alterations in lipid components, such as decreased high-density lipoprotein cholesterol (HDL-C), are associated with worsening intermittent claudication (IC) in postmenopausal women with PAD. Our cross-sectional cohort study included 69 postmenopausal women with IC (Fontaine stage II).
