Knowledge, attitudes, and barriers to carrier screening for the Ashkenazi Jewish panel: a Florida experience : Education and Barriers assessment for Jewish Genetic Diseases.

The knowledge, attitudes, and barriers to Jewish genetic diseases (JGDs) and screening and their relative importance in reproductive decision-making were assessed in a population-based sample of Ashkenazi Jewish young adults in Florida. These adults attended educational screening fairs hosted by The Victor Center for the Prevention of Jewish Genetic Diseases at the University of Miami. Parametric and nonparametric tests were used as appropriate to analyze data from a single group pretest/posttest design. Four hundred twelve individuals (mean age = 24.9; 54.7 % female, 45.3 % male) completed the questionnaires. Participants' level of knowledge increased from pre- to post-intervention (81.4 vs. 91.0 %; p < 0.0001). Concern about the possibility of being a carrier of a JGD was significantly higher after an educational session (5-point Likert scale mean difference = 0.45; p < 0.0001), as was their level of concern regarding having an affected child (mean difference = 0.20; p < 0.0001). The number of participants who agreed or strongly agreed that the test results would not have any influence on their reproductive behavior was lower after the session (17.2 vs. 20.8 %; p < 0.0001). This study demonstrates that an educational carrier screening program increased knowledge and elucidated awareness of the attitudes and barriers toward JGDs and carrier screening.

Association between northern Manhattan study global vascular risk score and successful aging.

OBJECTIVES: To examine the association between successful aging without subsequent cognitive decline (SA-ND) and the Northern Manhattan Study (NOMAS) global vascular risk score (GVRS), which is predictive of stroke, myocardial infarction, and vascular death. DESIGN: Prospective cohort study. SETTING: A stroke-free sample of Hispanic, black, and white participants living in the same community enrolled in a magnetic resonance imaging (MRI) substudy of NOMAS, a population-based prospective cohort study. PARTICIPANTS: One thousand two hundred ninety individuals in whom a cognitive screen was administered at baseline and at enrollment in the MRI substudy. MEASUREMENTS: SA-ND was based on disease, disability, and cognitive function. The GVRS includes age, sex, race and ethnicity, waist circumference, alcohol intake, smoking, physical activity, blood pressure, antihypertensive medication use, fasting blood sugar, lipid levels, and peripheral vascular disease. RESULTS: Data at baseline and follow-up were available for 1,162 participants (mean age 70 ± 9; 61% women; 13% white, 16% black, 69% Hispanic; mean GVRS 8.6 ± 0.9). Logistic regression, adjusted for education, socioeconomic status, and follow-up time, showed that the odds of SA-ND were 38% greater for each additional 1-point decrease on the GVRS (odds ratio = 1.38, 95% confidence interval = 1.17-1.61; P < .001). An inverse dose-response was observed between quartiles of GVRS and SA-ND. Greater diastolic blood pressure in participants taking antihypertensive medication and a history of claudication (P = .003) or peripheral arterial disease (P < .001) were inversely associated with SA-ND in the fully adjusted model. CONCLUSION: Potentially modifiable vascular risk factors were independently associated with SA-ND in a multiethnic community-based sample. Improvements in GVRSs could help promote healthy longevity in the aging population.

The aging mind: vascular health in normal cognitive aging.

In spite of the breakneck speed at which understanding of the biological basis of the aging process has evolved, the important determinants of aging and longevity have yet to be uncovered. The preservation of cognitive functioning is an essential component of successful aging, and the ability to distinguish those who maintain cognitive health into advanced age from those who experience cognitive decline may influence public health efforts to prevent or delay the onset of cognitive impairment in old age. There is growing evidence implicating vascular risk factors and related subclinical cerebrovascular damage in cognitive impairment and dementia, but Alzheimer's disease is highly prevalent in older populations, and the role of inflammation in vascular and neurodegenerative processes is poorly understood. There is a growing need to examine the effects of these factors on normal cognitive aging. This brief survey of the literature reviews evidence of the roles of subclinical vascular brain damage and exposure to cerebrovascular risk factors in normal cognitive aging.
