Filter by:The purpose of this study is evaluate the effectiveness of different doses of supervised exercise training intensity -concomitant to lifestyle counselling- as a Primary Health Care intervention tool for the management of the metabolic syndrome in low active adults with one or more metabolic risk factors. Secondary aims of the study are to investigate the effects of these interventions on systemic inflammation and adipose tissue function, cardiorespiratory fitness, physical activity and sedentary habits, and the cost-effectiveness of the intervention with regard to health related quality of life. The general hypothesis is that adults with risk factors for metabolic syndrome participating in interventions for the promotion of a healthy lifestyle that together with counselling strategies will include supervised physical exercise of vigorous intensity will present greater improvements in terms of metabolic risk, physical condition, physical activity/sedentary behaviours and psychological parameters at the end of the intervention and at 6-months follow-up than participants in interventions for the promotion of a healthy lifestyle that will include counselling plus physical exercise of low-to-moderate intensity or interventions based exclusively on counselling. It is a three arms controlled randomized clinical trial implemented in the Primary Health Care setting and of 10 months duration.
Cardio-metabolic risk factors include obesity, physical inactivity, smoke, alcohol abuse, high blood lipids or sugar and arterial hypertension. Systems for self-learning and self-monitoring may help people improve and maintain a healthy lifestyle through tailored suggestions about diet, weight control, physical activity, fatigue,stress. SEMEOTICONS exploits the human face as an indicator of individual's health status and translates signs obtained from the face using contactless sensors into measures and descriptors to be automatically evaluated by a an interactive smart mirror. This "Wize Mirror" extracts descriptors from videos, images and gas concentration signals and integrates them in a virtual model used to compute and trace the evolution of an individual's wellness index. A health diary enables each individual to evaluate and personally relate his/her lifestyle to his/her well-being. Coaching messages are provided, in relation to the evolution of the wellness index and of each descriptor, to provide useful suggestions on correct lifestyle self-monitoring. The purpose of this study is assess the accuracy of the information derived from the Wize Mirror in expressing the health status of the individual. The reproducibility and repeatability study will evaluate whether measurements are stable over short time spans and whether they are influenced by meals light and temperature conditions. To verify whether the Wize Mirror is able to detect variations in physical and emotional health status with appropriate lifestyle changes, the validation study will cross-check measurements from the Wize Mirror against reference clinical tests at enrolment and after 3 months of personalized suggestions for healthy behavior. Reference tests include - Physician visit - Measurement of blood oxygen content and skin end products of sugar metabolism,body composition, energy expenditure, vascular function - Laboratory profile and exhaled gas composition - Questionnaires on quality of life and lifestyle (food, sleep, physical activity, smoking, alcohol, stress). Wize Mirror measures include - 3D reconstruction of face images for roundness, color, stress and fatigue - Heart and respiratory rate - Detection of skin sugar metabolism end-products and of eye lipid deposits - Small vessel vasodilating ability with local heating The results will allow to assess whether the Wize Mirror is easy to use and helpful for self-monitoring of cardio-metabolic risk.
Fats and oils are made up of >90% triacylglycerol fat molecules which consist of a glycerol backbone to which 3 esterified fatty acids are attached. The positions of fatty acid attachment are referred to by stereospecific numbers, sn -1, -2 and -3. There is existing evidence to show that vegetable oils having unsaturated fatty acids in the sn-2 position with predominantly palmitic acid (16:0) or stearic acid (18:0) in the sn-1 and sn-3 positions of fat molecules do not raise serum cholesterol levels. These observations have come to be known as or explained by the "sn-2 hypothesis". New evidence have also emerged to show that saturated fatty acids (16:0, 18:0) in the sn-1 and -3 positions reduces fat deposition in a rat model. In this proposed study, the effects on the outcome measures investigated of three test fats [namely palm olein IV64 (POP), virgin olive oil (OOO) and cocoa butter (POS)], with oleic acid primarily at the sn-2 position but differing amounts of palmitic, stearic and oleic acids at the sn-1/sn-3 positions of the triglyceride molecule, are investigated
This study investigates the feasibility, acceptability, and effectiveness of adding Cognitive-Behavioral Therapy for Insomnia (CBT-I) to the standard care received at the Integrative Cardiac Health Project (ICHP) on insomnia symptoms and severity. ICHP is an established cardiovascular disease prevention program to reduce cardiovascular disease risk through the adoption of lifestyle changes related to improvements in diet, stress, sleep, and exercise. The study will be conducted among patients with insomnia who are already enrolled in the ICHP cardiovascular risk prevention program. This is a single-center study, prospective, randomized, controlled, interventional trial within ICHP at the Walter Reed National Military Medical Center (WRNMMC). To conduct both phases of the study, up to 76 total male and female patients enrolled in ICHP who meet criteria for insomnia will be recruited. Participants who meet inclusion and exclusion criteria for this study, and consent to participate, will be randomized to one of two conditions: (1) ICHP, or (2) ICHP + CBT-I treatment. CBT-I treatment will consist of four in-person appointments and two telephone appointments.
The study Sponsor, Heart Force Medical Inc. (HFM), has developed a patented medical device called the SPhENo-CardiographTM. The SPhENo-Cardiograph™ provides a non-invasive assessment of the electro-mechanical function of the heart. The electrocardiograph (ECG) represents the waveform of the electrical stimulus to the cardiac muscle. The mechanical actions of the electrical potentials delivered in the ECG are revealed as the seismocardiograph (SCG). The SCG represents the changes in acceleration of the heart during the cardiac cycle. The SCG waveform reflects the ultra-low frequency vibrations of cardiac contraction. These low frequency vibrations are transmitted through the sternum. Using the point of initiation of ventricular contraction on the ECG, the Q wave, with fiduciary points on the synchronous seismocardiograph, it is possible to determine timing events of the cardiac cycle. The timing events of the cardiac cycle during systole are referred to as Systolic Timing Intervals (STI) and comprise the Pre-Ejection Period (PEP) and the Left Ventricular Ejection Time (LVET). The PEP is the time from the Q wave to the Aortic valve opening. The Left Ventricular Eject Time (LVET) is the time between the Aortic Valve opening and closing. The ratio of PEP/LVET in individuals with established heart disease is > 0.42. It is based on the formula described by Dr Arnold Weissler and first published in Circulation in 1968 (Weissler et al,1968). Weissler et al showed that the PEP/LVET ratio >0.42 are indicative of a lengthening of the PEP with some marginal shortening of the LVET. This is indicative of pathology associated with the coronary circulation (Ahmed et al, 1972;). This ratio can then be used as part of a non-invasive quantitative assessment of cardiac performance (Lewis et al 1977). Using the SPhENo-CardiographTM, HFM has developed an algorithm to assess heart health that otherwise requires a number of technologies; stethoscope, ECG and Carotid pulse tracing to identify the dicrotic notch or Aortic Valve closure.

Is a randomized, double-blind, placebo-controlled trial to determine the behavior of hyperglycemia and postprandial lipemia after a standard mixed meal load in patients with carbohydrate intolerance treated with acarbose.
Red palm oil is obtained from crude palm oil through a novel low-temperature process. Owing to this special process, RPO possesses a special flavour and aroma, and is rich in phytonutrients that include carotenes, vitamin E, phytosterols, phospholipids, squalene, phenolic acids, flavonoids and co-enzyme Q10. These phytonutrients are the main constituents through which palm oil exhibits its nutritional properties. Among the major health promoting properties are anti-cancer, cardio-protection, anti-angiogenesis, cholesterol inhibition, brain development and neuro-protective properties, antioxidative defence mechanisms, provitamin A activity and anti-diabetes. As red palm oil has variety of phytonutrients and health benefits, the potential of improved cardiovascular health should be considered to understand better and thus treasure more our golden oil.
