Filter by:Cardiac output monitoring is mandatory in most surgical and critical care patients. Many techniques to assess cardiac output are invasive and/or have many limitations, contraindications and drawbacks. The measurement of cardiac output throughout the CO2 signal is an interesting option due to the simplicity and non-invasive nature of its calculation. The present study was designed to compare the cardiac output measurement using a capnodynamic formula versus the reference thermodilution method.
While observational studies often find that diets rich in fish reduce the risk of disease, and that diets including a high intake of red meat are associated with increased risk of cardiovascular disease and cancer, the difference in health effects between red meat and fish are rarely researched in intervention studies. The investigators hypothesise that the post-prandial plasma response of lipids and markers of cardiovascular disease risk will be more favourable after intake of herring compared to beef. In addition, while pickling herring in a brine/sugar solution is a common form of preparation, little is known if there is a difference in potential health effects based on the preparation of herring. The investigators will compare baked and pickled herring to understand if preparation is potentially an important factor to be considered when looking at intake of fish and health.
Background: - Heart disease is the leading cause of death and disabilities in the United States. Diets high in fruits and vegetables may reduce the risk of heart disease. Fruits, including red tart cherries and purple aroniaberries, may be especially beneficial. Researchers want to know how tart cherry and aroniaberry extracts affect heart health. Objective: - To study the benefits of tart cherry and aroniaberry extract on vascular function and other measures. These include inflammation, oxidation, and cholesterol. Eligibility: - Men and post-menopausal women ages 55 70 in good health and with normal or slightly high blood pressure or cholesterol. Design: - Participants will be screened with a physical exam, medical history, and blood tests. - Participants will have 6 visits. They will have blood taken at every visit. - Visit 1: - Blood vessel tests. Participants will lie down. Heart rhythm will be monitored. A device will be placed on the upper arm, and pictures of blood vessels will be taken. - A blood pressure cuff will be tightened around the lower arm for 5 minutes. - Cardio-Ankle-Vascular Index (CAVI). Blood pressure cuffs will be placed on both arms and legs. They will be tightened with air at the same time for a few minutes. - Participants will be assigned to one of three groups. For 3 weeks each, in random order, they will take: aroniaberry capsules, tart cherry capsules, placebo capsules, and no capsules. - Participants will answer questions online about their eating and exercise. - Participants will be keep a record of what they eat for a few periods. They will come for a study visit every 3 weeks through week 15.
The investigators propose to evaluate the implementation of an efficacious medication adherence program in a group at high risk for CVD. The program involves patients receiving/responding to e-reminders to take CVD medications via patient-selected technology [mobile/web-based applications, short message service (SMS; text messaging), interactive voice response (IVR), or e-mail] supported by a tailored, monthly, self-management program administered by either research staff or a case manager staff member from the Duke Outpatient Clinic via the telephone. This is a hybrid type II implementation science study.
This study is being conducted to evaluate the safety and the length of effect on platelet build-up in the arteries of Durlaza™ as compared to immediate-release Bayer® aspirin 81 mg or subject's current aspirin 81 mg of choice in patients who have Type 2 diabetes mellitus and cardiovascular disease or multiple risk factors of developing cardiovascular disease.
China Rural Health Initiative (CRHI), a large-scale, factorial, cluster-randomized, controlled trial was conducted in 120 villages selected from 5 Northern Provinces of rural China between 2010 and 2012. Two interventions were evaluated through CRHI. One is the standard disease management program of individuals at high risk of cardiovascular disease delivered by Primary Care Providers (village doctors). Another one is a community-based Salt Reduction program delivered by community health educators. CRHI study interventions had ended for two years now and provide a good opportunity for us to understand whether its effects could be prolonged to a longer term. This study wants to evaluate the effects of CRHI interventions at 2 years after the end of CRHI (from Sep 2014 to Feb 2015). In this follow-up survey, the baseline cohort of 5050 and post-intervention cohort of 4887 CRHI participants who were randomly selected from the 120 villages from 5 northern provinces of rural China will be recruited for the follow up study from Sep 2014 to Feb 2015. A questionnaire derived from CRHI baseline and post-intervention surveys will be used to collect data on disease history, medication use, care seeking patterns, lifestyle factors and so on. Weight, height, blood pressure and heart rate will be measured in the standard ways.
Cardiovascular disease (CVD) is largely a lifestyle-related condition that is the #1 killer of adults in the United States. Our work is aimed at understanding how short-term increases in blood sugar, like those that accompany eating a meal, affect blood vessel function and the risk of CVD. This research is aimed at understanding how meals composed of eggs affect short-term increases in blood sugar from eating, which are connected with increased risk of CVD. In particular, the investigators are trying to identify a specific meal composed of either whole eggs, egg yolks, or egg whites, that best reduces acute increases in blood sugar brought on by meals that consist of majority carbohydrate. At the same time, the investigators are trying to explore the protective affects that eggs may have on blood vessel function and the reduction of CVD risk.
Supplementation studies with vitamin D have been performed where cardiometabolic risk markers have been assessed but these are few, and results are inconsistent. Hence, the purpose of this study is to determine: 1. Whether administering supplemental Vitamin D3 at a dose of 5000IU/day (125µg) in overweight and obese adult participants for 8 weeks will significantly increase circulating concentrations of 25(OH)D or achieve optimal vitamin D status. 2. Whether administering supplemental Vitamin D3 at a dose of 5000IU/day (125µg) in overweight and obese participants for 8 weeks will significantly improve the cardiometabolic parameters measured. 3. To evaluate the relationship between these variables and 25(OH)D concentration. We hypothesise that there will be a significant increase in plasma 25(OH)D following 8 weeks (56days) supplementation of oral vitamin D3 at a dose of 5000IU/day (125µg); Administering supplemental Vitamin D3 at a dose of 5000IU/day (125µg) in overweight and obese participants for 8 weeks will significantly improve the cardio metabolic parameters measured, and there will be a relationship between these variables and 25(OH)D concentrations.
Association between serum magnesium and clinical outcome in patients with acute MI (AMI) with 1 year follow-up in 300 patients in regions supplied by desalinated drinking water (DSW) (Sheba MC) and 150 patients in regions with non-desalinated drinking water (DW) (Nahariya MC).
The proposed research brings together complementary expertise to systematically elucidate the longitudinal effects of (1) total and regional body fat and (2) the metabolic impairment that accompanies obesity on bone development during growth. The contribution of this research will be significant because it will provide a solid foundation for understanding the influence of fat (total and regional distribution) on overall bone strength, and whether insulin resistance, beta-cell dysfunction, abnormal lipids, and inflammation could be underpinning factors in the fat-bone strength relationship via effects on bone modeling activity. This knowledge will provide critical information needed to maximize potential therapeutic interventions to counter the linked risks of obesity and osteoporosis, both major public health concerns.
