This study focuses on analyzing the data collected from participants in the Faculty/Staff Exercise Program to determine the success and quantifying the results of the program. The investigators are interested in the effectiveness of this program on multiple levels, individual and group, as it is the first of its kind - an exercise program targeting the faculty and staff at a university.
The present study will analyze if exercise is able to elicit the well-known anti-atherogenic effects in patients with SCI. This will be evaluated by measuring vascular parameters such as endothelial and inflammatory blood markers, echocardiography of the heart and peripheral vessels, as well as blood pressure and arterial stiffness, in subjects performing either wheelchair dancing, wheelchair marathon or no sports. Further, it will be investigated, whether there is an association between neuroplasticity and cardiovascular health, as measured by electroencephalography (EEG), transcranial magnetic stimulation (TMS) and blood levels of the brain-derived neurotrophic factor (BDNF). We hypothesize that the cardiovascular, physical and psychological benefits of wheelchair dancing and/or wheelchair marathon parallel improved neuroplasticity in SCI-patients
The study will explore the capacity for a lifestyle modification in firefighters to improve blood pressure, blood vessel stiffness, inflammation, and reduce oxidative stress. The study will be a pre- post-testing controlled trial with three groups. The intervention will be a weekly circuit workout program and a Mediterranean (high fruit/vegetable) diet. The groups will be firefighters with >10yrs experience, firefighters with <10yrs experience, and control Non-firefighters.
This study was a parallel randomized controlled feeding trial conducted in overweight and obese participants who were attending the Nutrition Clinic in Isfahan, Iran. Inclusion criteria were as follows: women aged 18 to 50 years; body mass index (BMI) 25 kg/m2 ; having noncommunicable diseases such as diabetes, hyperlipidemia, and hypertension; having no history of liver and renal disease, hormonal disorders, food allergy, and other special diseases; not taking specific medications affecting weight; willingness to introduce a dietary change to lose weight; and habitual daily consumption of fruits, vegetables, and whole grains. The exclusion criteria were the following: weight loss of more than 10% of body weight within the 6 months before registration in the study; attending a competitive sport; no consumption of fruits, vegetables, or whole grains habitually; abnormal thyroid hormone concentration; intake of drugs or supplementation that could affect energy expenditure or weight; and not following recommended diets or returning for following visits. Recruitment ran from January 2016 to July 2016. The sample size was calculated based on the standard formula (45): by considering the Type 1 error (a) of 0.05 and Type 2 error (b) of 0.20 (power D 80%). Based on a previous study in Iranian women (46), we used a within-group BMI mean difference (d) of 2.5 kg/m2 and a standard deviation (SD) of 3.2 kg/m2 - Therefore, we needed 25 participants in each group. The study was approved by the research council and ethical committee of the School of Nutrition and Food Science, Isfahan University of Medical Sciences, Isfahan, Iran (grant number: 194172). All participants gave written consent before study enrollment. This trial was registered at ClinicalTrial.gov with code NCT03340298. Study design and interventions A randomized feeding trial was designed that aimed to compare the effect of different sources of fibers with low-calorie conventional diets on weight loss, waist circumference (WC), blood pressure, fasting blood glucose (FBS), and lipid profiles in overweight and obese women. Eligible participants were randomly assigned to the three groups after baseline measures of BMI, using a computer-generated random numbers method of randomization. Seventy-five participants who were eligible for the study were randomly divided to one of the three groups ("whole grains" high fiber diet, "fruits and vegetables" high fiber diet, and diet containing "whole grains, fruits, and vegetables") in a 1:1:1 allocation (Figure 2). Participant allocation was stratified by age and BMI. All participants consumed 35 g of fiber per day as follows: in the whole grains group (n D 25), 25 g of fiber from whole grain products and 10 g fiber from fruits and vegetables was to be consumed with the main meals; in the fruits and vegetables group (n D 25), 25 g of fiber from fruits and vegetables and 10 g from whole grain sources was to be consumed with the main meals; and in the whole grains, fruits, and vegetables group, participants were to consume an equal amount of fiber from both sources (17.5 g fiber from whole grains and 17.5 g fiber from fruits and vegetables) with their main meals daily for 10 weeks. The main meals were determined by an expert dietitian, based on the Harris-Benedict formula, considering 0.5 kg weekly weight loss for each participant. The distribution of macronutrients was similar among groups (carbohydrates, 55%; fat, 30%; and protein, 15%) and the number of servings of each food group was estimated and given to participants. Participants in each group were given their allowed food that contained a list of exchangeable foods, food groups, and subgroups (Table 2). All participants were instructed to attend the nutrition clinic to take their intended products. Participants were supplied with the fruits, vegetables, and whole grains for their diet and they consumed these food items under supervision in the nutrition clinic for 10 weeks. Other components of their weight loss diets, such as dairy, meats/alternatives, and fat groups were asked to be consumed in a free-living situation. To assess compliance of participants' intake of weight loss diets, participants were asked to record their 24-hour food intakes for 3 d/wk during weeks 2, 5, and 10 of the trial. Duration of all physical activities was collected, similar to dietary intakes. To obtain the metabolic equivalent for daily physical activity, the recorded physical activities were multiplied by the relevant metabolic equivalents task hours per day (MET-h/d) to give the MET-h/d values.
The study is designed evaluate the effects of a new combination of nutraceuticals (AkP 06) without Monacolin K on lipid and glucose metabolism. The study will analyze the impact of 4 weeks treatment with Akp06 or placebo, according to a randomized scheme, on metabolic parameters in dyslipidemic subjects that do not require or not tolerate a statin therapy. In particular, it will assess the ability of AkP 06 to reduce the plasma levels of LDL cholesterol, HbA1C, glicaemia and fasting insulin and to increase those of HDL cholesterol. In addition, effects on serum transaminase and creatine phosphokinase (CPK) concentration will be evaluated.
The investigators propose a randomized controlled effectiveness trial to evaluate the integrated clinic-community model of child obesity treatment as compared with routine primary care.
Diseases such as hypertension and stroke affect mid-life and older African Americans at higher rates than Whites, negatively affecting health status of this group. This project determine the effectiveness of a faith-based health intervention for mid-life and older African Americans using community-based participatory research approaches.
Research show that South Asians (SA) have a high burden of Cardiovascular Disease (CVD) risk factors of which, poor diet and physical inactivity remain the major lifestyle risk factors in SA. Intensive diet and physical activity behavioral interventions have been shown to yield improvements across a variety of intermediate cardiovascular health outcomes (blood pressure, cholesterol, glycated hemoglobin, weight) in persons with CVD risk factors and are recommended by national guidelines. However, the investigators prior research found that existing interventions are not reaching SA. First, the usual framing of behavioral risk factor interventions in terms of the biomedical model of CVD is mismatched to SA explanatory models, which emphasize psychosocial causes of CVD. Next, few interventions are tailored to the sociocultural patterns shared by much of the SA community. Interventions that address the individual and shared sociocultural drivers of CVD risk are needed to maximize reach and effectiveness in the high risk and rapidly growing SA population. The proposed study builds on the strong foundation of the South Asian Healthy Lifestyle Initiative (SAHELI), which has a 9-year history of using community-based participatory research to design and test culturally tailored, community-based interventions to reduce CVD disparities in SA. To date, SAHELI has engaged multi-sectoral partners, established relationships of trust, and defined mutually beneficial goals. The investigators also culturally adapted the SAHELI lifestyle intervention to (a) address the individual and sociocultural determinants of CVD risk in SA; and (b) increase components of self-regulation (motivation, self-monitoring, goal setting) that are most effective in eliciting diet and physical activity changes. Hence, the SAHELI intervention integrates evidence-based behavior change techniques with the shared the sociocultural processes salient to SA. A pilot study (n=63) established feasibility of the SAHELI intervention, had a 100% retention rate, and reduced glycated hemoglobin and weight among intervention participants compared to a control group. The proposed study is based on the pilot study and will use a hybrid trial type 1 design to evaluate the clinical effectiveness and implementation potential of the culturally tailored, community-based lifestyle intervention in a larger, more generalizable at-risk SA population. Study team is uniquely positioned to fill a critical gap in work (a) demonstrating the cultural adaptation of evidence-based lifestyle interventions, and (b) evaluating the effectiveness of the SAHELI intervention in reducing CVD risk in SA living in the U.S.
Trimethylamine-N-oxide (TMAO), a metabolite produced by gut microbial metabolism of dietary choline, has recently been causally linked to atherosclerosis in animal models and has been shown to be predictive of cardiovascular disease (CVD) risk in some but not all cohort studies. The relevance of observations in animals to humans is unclear and little information is available on the mechanisms linking TMAO to increased CVD risk. Vascular dysfunction plays a critical role in the initiation and progression of atherothrombotic disease. Whether TMAO impairs vascular function in humans is not known. The purpose of this study is to determine if short term supplementation of dietary choline, which increase TMAO, impairs vascular function.
