Effects of White Potato Consumption on Measures of Cardiometabolic Health in Individuals With Type 2 Diabetes Mellitus

Start date: April 27, 2019
Phase: N/A
Study type: Interventional

The investigators are examining the effects of potato consumption on indices of glycemic control and cardiovascular health in overweight and obese individuals with type two diabetes mellitus (T2D) to provide feasible and effective dietary ways for individuals to enhance their quality of life. The overall objective of this crossover study is to collect data regarding the effects of potato consumption on indices of glycemic control and cardiovascular health among overweight and obese individuals with T2D. The central hypothesis of this crossover study is that the daily consumption of 100 g white potato for 12 weeks will contribute to improvements in glycemic control, reductions in inflammation, and improvements in blood lipids and vascular function in overweight and obese individuals with T2D compared to a macronutrient-matched refined grain (75 g cooked long-grain white rice) for 12 weeks (with a 2 week washout period between interventions). Specific Aim) The assessment of blood glucose control, vascular function, body composition and overall cardiovascular risk after consumption of potatoes (100g/d for 12 weeks) in individuals with T2D compared to a calorie matched refined grain at the initial baseline visit as well as the 6-, and 12-week study visits (for each 12-week intervention period). This aim will assess changed in blood glucose, insulin, HbA1c, HOMA-IR, and HOMA-β as well as the following: 1. blood pressure (BP) 2. markers of endothelial function [flow-mediated dilation (FMD), pulse wave velocity (PWV), and endothelin-1 (ET-1)] 3. markers of inflammation (C-reactive protein) 4. body composition via bioelectrical impedance (BIA), lean mass and fat mass assessment 5. lipid profiles, consisting of total cholesterol (TC), triglycerides (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and oxidized LDL (Ox-LDL). Atherogenic risk ratios (TC/HDL-C, LDL-C/HDL-C, HDL-C/LDL-C) will also be assessed 6. anthropometrics [weight, height, waist circumference (WC), hip circumference (HC), waist-to-hip ratio (WC/HC)]

NCT ID: NCT04049162 Completed - Clinical trials for Overweight and Obesity

Blueberry Enhances Activity and Cognition Through Increased Vascular Efficiency

BEACTIVE
Start date: September 20, 2019
Phase: N/A
Study type: Interventional

Recent evidence suggests that increased berry intake results in a variety of health benefits, across multiple health domains. This 3-month randomized, double-blind, placebo-controlled trial assess the effects of combining daily blueberry intake with weekly exercise (BB-EX) on cardiovascular function, as well as physical activity and cognitive function, in sedentary older adults (>60 years). We will compare these effects to the same outcomes with a control group consuming a blueberry placebo (P-EX) at 0, 4, 8 and 12 weeks.

MIVAS
Start date: April 3, 2019
Phase:
Study type: Observational

This is an observational case-control study which objective is to analyse differences in intestinal microbiota between patients with and without arterial stiffness, measured by pulse wave velocity. It will take place in two different research units located in Portugal and Spain.

NCT ID: NCT03649802 Completed - Clinical trials for Vitamin D Deficiency

Vitamin D and Arterial Stiffness in Elderly

Start date: August 16, 2018
Phase: Phase 2
Study type: Interventional

Investigators will examine arterial stiffness and pulse waveform analysis. Subjects with vitamin D insufficiency will be recruited. A double blind randomized controlled study will examine the effects of standard dose vitamin D3 (800 IU) versus higher dose vitamin D3 (5000 IU)-given on a daily basis.In order to understand mechanisms of action by which vitamin D would improve arterial stiffness investigators will use biomarkers. Oxidative and inflammatory stress will be measured by plasma F2-isoprostanes and Sulforaphane levels.

NCT ID: NCT03626168 Completed - Inflammation Clinical Trials

Bioactive Compounds in Watermelon Modulating Oxidative Stress and Inflammation in Elders

MOXIE
Start date: February 16, 2016
Phase: N/A
Study type: Interventional

Watermelon is the only food with a unique combination of amino acids and antioxidants that may reduce artery stiffness. However, only 27% of older adults meet the daily recommendation for fruit intake. Because it tastes good and is convenient and easy to consume, watermelon juice is an innovative and impactful intervention to help elders easily meet recommendations for fruit servings. If effective, this intervention would be a simple, inexpensive way to combat cardiovascular diseases (CVD). Results will advance science by providing a better understanding whether four-week consumption of 100% watermelon juice may impact measures of vascular health and inflammation in postmenopausal women.

NCT ID: NCT03560804 Completed - Arterial Stiffness Clinical Trials

Use of Impedance Cardiography and Applanation Tonometry for Prediction of the Antihypertensive Effect of Two Drugs

Start date: November 10, 2014
Phase: N/A
Study type: Interventional

The principal aim of the study is to determine whether the hemodynamic parameters measured with the two methods -impedance cardiography and applanation tonometry- can be predictive of the antihypertensive effect of two different classes of drugs, ATII antagonists and diuretics. The drugs that will be used in the study are olmesartan and chlorthalidone and the duration of the study is 12 months. The other basic aim of the study is to determine whether there is a difference (>6mmHg) between the two drugs regarding the reduction of the mean 24hour blood pressure and the effect of them on the hemodynamic parameters. The hemodynamic parameters that will be measured by applanation tonometry are augmentation index, central blood pressure and pulse wave velocity. The hemodynamic parameters that will be measured by impedance cardiography are cardiac index, thoracic fluid content index, systemic vascular resistance index and others.

NCT ID: NCT03415880 Completed - Diabetes Mellitus Clinical Trials

Light Intensity Physical Activity Trial

LiPAT
Start date: November 8, 2018
Phase: N/A
Study type: Interventional

In type 2 diabetes (T2D), physical activity is an important modifiable risk factor of cardiovascular disease (CVD). Unfortunately (long-term) compliance to exercise programs in patients with T2D is poor. Light-intensity physical activity (LiPA) such as walking slowly, household activities or taking a flight of stairs might be a potential target for lowering the CVD risk in patients with T2D since it can perhaps be more be incorporated into daily life. To assess cardiovascular disease risk in this single-blinded RCT, the investigators settled on measuring arterial stiffness as the primary outcome. Arterial stiffness has independent predictive value for cardiovascular events and can be measured reliably and non-invasively. The investigators hypothesize that light intensity physical activity intervention program based upon increasing LiPA by replacing sedentary time is effective in lowering arterial stiffness as estimated by aortic pulse wave velocity (PWV) and carotid distensibility in individuals with T2D.

NCT ID: NCT03223441 Completed - Arterial Stiffness Clinical Trials

Pulse Wave Velocity as a Predictor for Postoperative Cardiovascular Events

Start date: June 2015
Phase:
Study type: Observational

Vascular stiffness increases as a person ages, due to the repetitive stress that is put on the vascular system which causes changes in the elasticity of the vessel walls. The increased stiffness of the arteries puts added stress on the circulatory system. This rise in stiffness has been shown to be associated with an increased risk of cardiovascular events, in both presumably healthy patients, as well as elderly patients The current method for assessing perioperative cardiac risk is the Goldman's Revised Cardiac Risk Index (RCRI). This method, however, does not include a direct measurement of arterial stiffness. Applanation tonometry is a non-invasive technique that has been shown to reliably provide indices of arterial stiffness While the use of applanation tonometry has been widely studied in general medicine, it is has not been studied for pre-operative risk assessment in surgical patients. The purpose of this investigation is to examine whether aortic stiffness is an independent risk factor for developing cardiovascular related adverse events in patients who are having major surgery under general anesthesia. Applanation tonometry will be performed on the right carotid and femoral arteries to assess carotid-femoral pulse wave velocity, a surrogate for aortic stiffness. (SphygmoCor system, AtCor Medical, Sydney, Australia). The measurement will be obtained before induction of general anesthesia in the presurgical area. Patients' medical history, intraoperative hemodynamics, and any postoperative complications will be recorded to determine significant correlations and relationships. This information will potentially help identify future patients that might be at greater risk of developing an adverse cardiovascular event following their surgical procedure.
