BACKGROUND The association between antecedent head injury and AD is inconsistent. OBJECTIVE To examine the association between early adult head injury, as documented by military hospital records, and dementia in late life; and to evaluate the interaction between head injury and APOE epsilon4 as risk factors for dementia. METHODS The study had a(More)
Measurements of erythrocytes within the blood are important clinical traits and can indicate various hematological disorders. We report here genome-wide association studies (GWAS) for six erythrocyte traits, including hemoglobin concentration (Hb), hematocrit (Hct), mean corpuscular volume (MCV), mean corpuscular hemoglobin (MCH), mean corpuscular(More)
BACKGROUND Depressive symptoms are common and can be debilitating in the months after head injury. Head injury can also have long-term cognitive effects, but little is known about the long-term risk of depression associated with head injury. We investigated the lifetime rates of depressive illness 50 years after closed head injury. METHODS Participants(More)
OBJECTIVE It has been hypothesized that adequate concentrations of vitamin B(12) and folate are essential to maintain the integrity of the neurological systems involved in mood regulation, but epidemiologic evidence for such a link in the general population is unavailable. This study examined whether community-dwelling older women with metabolically(More)
BACKGROUND Bisphenol A (BPA) is a high production volume chemical widely used in packaging for food and beverages. Numerous studies have demonstrated that BPA can alter endocrine function in animals, yet human studies remain limited. OBJECTIVE We estimated daily excretion of BPA among adults and examined hypothesized associations with serum estrogen and(More)
BACKGROUND previous studies have reported an association between cognitive function and physical performance, particularly among older adults. OBJECTIVE to examine the association between executive function and performance difference on complex versus usual walking tasks in a sample of non-demented older adults. DESIGN population-based epidemiological(More)
We hypothesized that the rising levels of inflammatory markers with aging is explained by cardiovascular risk factors and morbidity becoming progressively more prevalent in older persons. Information on inflammatory markers, cardiovascular risk factors, and diseases was collected in 595 men and 748 women sampled from the general population (age, 20-102(More)
The human interleukin IL-6 was originally cloned in 1986. In 1993, William Ershler, in his article "IL-6: A Cytokine for Gerontologists," indicated IL-6 as one of the main signaling pathways modulating the complex relationship between aging and chronic morbidity. Over the last 12 years, our understanding of the role of IL-6 in human physiology and pathology(More)
BACKGROUND Low muscle mass and weakness are common and potentially disabling in older adults, but in order to become recognized as a clinical condition, criteria for diagnosis should be based on clinically relevant thresholds and independently validated. The Foundation for the National Institutes of Health Biomarkers Consortium Sarcopenia Project used an(More)
High serum uric acid levels elevate pro-inflammatory-state gout crystal arthropathy and place individuals at high risk for cardiovascular morbidity and mortality. Genome-wide scans in the genetically isolated Sardinian population identified variants associated with serum uric acid levels as a quantitative trait. They mapped within GLUT9, a Chromosome 4(More)
