Filter by:BACKGROUND. Sleep deficiency (not getting enough sleep) is widespread in American adults and can lead to many harmful health outcomes such as a higher risk of obesity, heart disease, and diabetes. Sleep deficiency can also harm cognitive performance, which refers to one's awareness and thinking ability. Sleep deficiency and sleep-related health issues are of high interest among those who have irregular and/or extended work schedules, because such schedules can interfere with normal biological rhythms of sleepiness and wakefulness. PURPOSE. This study will examine the health and cognitive effects of work schedule and sleep patterns in caregivers (such as nurses, laboratory technicians, and non-clinical hospital staff). The investigators hypothesize that the nontraditional, irregular, and extended work hours common in these professions will have adverse health and cognitive effects. The purposes of this protocol are to: - Enroll caregivers into a one year cohort study on the relationships among work schedule, sleep, diet, chronic disease, and cognitive performance. (A cohort study follows a group of participants over time to see how different behaviors or risk factors affect health.) - Collect data from caregivers on work schedule, sleep, diet, chronic disease, and cognitive performance. - Give personalized information and feedback to caregivers about these health factors. - Educate caregivers about healthy diet and exercise choices. - Collect saliva from caregivers for future research on the role of genes in health. (Specimen collection for genetic testing will be offered as a separate option for study participants.) RECRUITMENT. This study will use the Let's Get Healthy! health research and education program (OHSU IRB #3694) as a platform for recruitment and data collection. Caregivers will be invited to participate in a Let's Get Healthy! event and will be given information prior to the event about the cohort study. At the Let's Get Healthy! event, caregivers will first consent to the anonymous research study (OHSU IRB #3694), in which demographic and health screening data are linked to a random number. Caregivers will then have the option to consent to a cohort study, in which data are no longer anonymous but instead linked to participants' names and contact information. PROCEDURES. This cohort study piggybacks on procedures already approved for the Let's Get Healthy! program (OHSU IRB #3694). Let's Get Healthy! is a study in which participants provide anonymous data at health fairs through any or all of the following manners: short computer surveys on cancer awareness, risk factors, and family history (with immediate feedback given on cancer risk and prevention); short computer surveys on diet and sleep patterns (with immediate printed feedback given); health screening measurements (blood pressure, height, weight, waist circumference, body mass index, body fat percentage); a finger stick to assess sugar and fat levels in blood; and a mouthwash swish to provide a saliva specimen. However, this cohort study (OHSU IRB #7542) will make the following changes and additions: - Personal health data, instead of being anonymous, will be linked to participants' names and contact information (for follow-up data collection). - Let's Get Healthy! events will include cognitive performance tests, a preventative-care survey, and a work schedule survey. - Participants will provide data not only at an initial Let's Get Healthy! event, but also at a follow-up event and during the time period between events. Between events, participants will do the surveys on work schedule, diet, and sleep, and they will complete cognitive performance tests. - There will be a separate consent process for participants to provide a fully identifiable saliva specimen. DATA ANALYSIS. Participants' health data will be fully identifiable at the time of data collection but will be coded and stored in a physically separate location from the identifiable information. The link between identifiable information and coded health information will be stored on a password protected computer, and all identifiable information will be deleted upon completion of data analyses. Data will be analyzed to explore relationships among work schedule, sleep, diet, body composition, metabolic health, chronic disease, and cognitive performance in caregivers. Genetic relationships with these factors will be analyzed in those who provided a saliva specimen during entry visit data collection.
Functional brown adipose tissue (BAT) exists in adult humans and can be detected by PET and especially during acute cold exposure. It is conceivable that BAT activity might reduce the risk of developing obesity since fat stores are used for thermogenesis, and a directed enhancement of adipocyte metabolism might have value in weight reduction. So it is important to know the different metabolic characteristics in human adults who have detected BAT. Therefore, the purpose of the investigators study is to compare different metabolic characteristics in the presence of brown adipose tissue in humans.
Linkages between depression and cardiovascular disease have been well documented. These appear to be more than associations, and may reflect causal relationships through a number of proposed pathways, including decreased physical activity, poor dietary habits, medication non-adherence, and a direct impact on inflammatory mediators. Older adults are affected by both depression and heart disease, with increased risk in African American and Latino elderly. The BRIGHTEN-Heart trial tests the hypothesis that an enhanced primary care delivery system intervention which provides evidence-based, patient-centered mental health services targeting depression and cardiovascular risk factors can reduce the risk of development of cardiovascular disease in low-income elderly blacks and Hispanics. BRIGHTEN stands for Bridging Resources of a Geriatric Health Team via Electronic Networking, and in this intervention, specialty providers including geropsychologists, social workers, pharmacists, nutritionists, chaplains, occupational therapists, and others collaborate via the internet as a virtual team. The study will determine if such a virtual interdisciplinary clinical team collaboration can reduce depression in older (age ≥ 65) minority adults with comorbid depression and metabolic syndrome.
Dietary polyphenols might have beneficial effects on glucose and lipid metabolism based on the studies made in animals or cell cultures. The findings regarding the possible decrease of low-grade inflammation are existing also in humans. Low-grade inflammation has been suggested to be a mechanistic link between obesity and its consequences on cardiometabolic health. The aim of the present study is to examine the effect of diet rich in berries on glucose and lipid metabolism and inflammatory markers.
The purpose of this study is to examine the effects of walnut consumption on endothelial function and lipid markers in overweight patients with at least one factor of metabolic syndrome as compared to the control group.
Metabolic syndrome (MS) is a significant risk factor of cardiovascular disease. However, the relationships between coenzyme Q10, antioxidant vitamins (Vitamin A, C, E) and the prevention of the risk of MS are still inconsistent. The purposes of this study are going to investigate the relation of coenzyme Q10, antioxidant vitamins concentration with the blood lipid levels, the markers of lipid peroxidation (TBARS), antioxidant enzymes activities (catalase, glutathione peroxidase and superoxide dismutase), and the inflammatory markers (hs-CRP,IL-6 and adiponectin). The investigators will recruit MS patients (case group, n = 100) and age-gender matched healthy subjects from previous study(n = 105) as a control group . The inclusion criteria of MS are according to the Bureau of Health Promotion, Department of Health in Taiwan (2007).Hopefully, the results of this study could provide the information to what has been know in MS subjects. The investigators expect coenzyme Q10 or antioxidant vitamins could be a preventive supplement to reduce the risk of MS.
The purpose of this study is to define whether the acute consumption of low-fat milk protects against postprandial vascular endothelial dysfunction by reducing oxidative stress responses that limit nitric oxide bioavailability to the vascular endothelium. The investigators hypothesis is that the consumption of low-fat milk will improve postprandial vascular endothelial function in an oxidative stress-dependent manner that allows greater nitric oxide (NO) bioavailability. The objectives of this study are to 1) examine improvements in postprandial vascular endothelial function in response to low-fat milk ingestion, 2) define low-fat milk-mediated improvements in circulating biomarkers of redox status, and 3) define the mechanism by which low-fat milk improves NO bioavailability. Collectively, the successful completion of these studies is expected to define NO mediated activities of low-fat milk that protect against vascular endothelial dysfunction in individuals at high risk for developing CVD.
Pulses have the potential to be positioned as a food for body weight and metabolic control based on their composition, effects on rate of digestion and absorption of fat and carbohydrates, and effects on satiety. However, the role of individual pulses incorporated into a mixed meal on regulation of food intake, satiety and glycaemic control remains unclear. Therefore, the objective of our study was to determine the effects of ad libitum consumption of pulse meals (treatments) on food intake at an ad libitum pulse meal, food intake at an ad libitum pizza meal at four hours, subjective appetite and blood glucose.
A prospective, randomized, controlled, open-label study will be carried out on 80 post-menopausal women affected by the metabolic syndrome (criteria are described in NIH ATP III). After a written informed consent, women will be randomly treated for 6 months with hypocaloric diet (control group) or with diet and a supplementation of myo-inositol 2000 mg plus cocoa polyphenols 30 mg and plus isoflavones 80 mg. will be given randomly Eighty post-menopausal women, affected by metabolic syndrome will be randomized into two groups: 40 treated with myo-inositol 2 g twice per day and forty treated with placebo for six months. The investigators hypothesize that the administration of myo-inositol would improve the insulin-receptor activity in these women, reducing insulin resistance.
The study will enroll 68 overweight male and female subjects with a high (> 2 3dl-can soda/day) consumption of sweetened beverage per day. After a run-in period of 4 weeks, subjects will be randomized to either a 12-week intervention arm in which sweetened beverages will be replaced by artificially sweetened, calorie-free beverages, or to a control arm. The following measurements will be performed at the end of the run-in period and at the end of the intervention period - intrahepatic fat concentration - visceral fat volume - changes in day-long metabolic profile from baseline(plasma glucose, insulin, and triglyceride concentrations) - changes in food intake and daily energy, carbohydrate and sugars intake from baseline
