Lowering of blood pressure (BP) in high-risk hypertensive individuals reduces major adverse cardiovascular and cerebrovascular events. Diabetic patients with hypertension benefit from BP lowering treatment. The present trial, IPAD in brief, is a randomized, open-label, parallel-designed, multicenter study involving nearly 12,000 patients to be recruited and to be followed up for a median of four years. IPAD tests the hypothesis that antihypertensive medications in adults with type 2 diabetes, whose seated BP 120-139 mm Hg systolic and below 90 mm Hg diastolic, results in 20% difference in the incidence of major adverse cardiovascular and cerebrovascular events. During follow-up for participants in the intensive group, the sitting systolic pressure should be decreased to below 120 mm Hg, by titration and combination of the study medications of an angiotensin type-1 receptor blocker Allisartan (240 mg/day), a dihydropyridine calcium-channel blocker (amlodipine 5-10 mg/day), and/or other medications if necessary. For those in the standard group, the sitting systolic pressure should be monitored and controlled below 140 mm Hg.
A prospective double blind, placebo-controlled, randomized cross-over trial to evaluate the effect of lowering cerebral blood flow on the ventilatory chemoreflexes (acute hypoxic and hypercapnic ventilatory responses).
This study aims to evaluate whether dietary supplementation with fish oil can protect against the cardiopulmonary alterations linked to air pollution
Food insecurity increases the risk of obesity, diabetes, hypertension, and cancer. American Indians (AIs) in Oklahoma are three times as likely as Whites to be food-insecure (21% vs. 7%) and have burdens of obesity (42%), hypertension (38%), and diabetes (15%) that exceed those of the general US population. While individual-level obesity prevention efforts have been implemented with AIs, few environmental interventions to reduce food insecurity and improve fruit and vegetable intake have been conducted with tribal communities. Community gardening interventions have been shown to increase vegetable and fruit intake, reduce food insecurity, and lower BMI among children and adults; however, to date, no such interventions have been evaluated with AI families. The proposed study, entitled "Food Equity Resource and Sustainability for Health (FRESH)," will assess the impact of a tribally-initiated community gardening intervention on vegetable and fruit intake, food insecurity, BMI, and blood pressure in families living on the Osage Nation reservation in Oklahoma.
Mechanical ventilation has been known to produce changes in the flow of blood through the major blood vessels in the body. These changes may go undetected, but with continuous arterial blood pressure measurements, changes in the arterial waveform can be visualized. Although we know that these arterial pressure variations occur during mechanical ventilation, little is known about the effects of various modes of mechanical ventilation on these changes. The most common modes of ventilation used in ICU are Volume control, Pressure control and Airway pressure release ventilation. Objective We have designed a prospective randomized pilot study to determine the effects of the commonly used ventilator modes on the arterial pressure.
This study will use contrast echocardiography to assess the accuracy of a new non-invasive imaging method for subharmonic aided pressure estimation (SHAPE) compared to simultaneously acquired intra-cardiac pressures measured invasively during cardiac catheterization. This study is designed to verify that contrast echocardiography using the SHAPE method, already proven in a canine model and tested in a human pilot study can be used as a surrogate for cardiac catheterization with sufficient accuracy to allow clinical applicability in humans.
The fundamental hypothesis of this project is that real-time intracardiac pressures can be monitored and quantified noninvasively in humans using a novel contrast-enhanced ultrasound technique called subharmonic-aided pressure estimation (SHAPE).This study will use contrast echocardiography to assess the accuracy of SHAPE compared to simultaneously acquired intracardiac pressures measured invasively during cardiac catheterization. This study is designed to verify that contrast echocardiography using the SHAPE method, already proven in a canine model and tested in a human pilot study can be used as a surrogate for cardiac catheterization with sufficient accuracy to allow clinical applicability in humans.
The purpose of the study is to compare 3 different diets in pregnancy, equal in calories, and fats, different in refined grains compared to whole grains as a source of carbohydrates, and in calories from carbohydrate, compared to protein as a source of calories.The hypothesis is that there will be differences in the specified outcomes because the proportions of macronutrients are significant. The primary objective is to detect differences in weight gain.
INTRODUCTION: Accurate estimation of dry weight (DW) is an important and difficult problem in clinical practice. DW is defined as the lowest weight after hemodialysis (HD) where the patient will not develop symptoms of hypotension and edema, in addition to not using antihypertensives. Achieving a fluid balance benefits the control of blood pressure and reduces cardiovascular risk. In most HD centers, the DW is estimated using a subjective method dependent on the signs and symptoms that the patient presents. Recently, several approaches have been studied to develop a standardized DW evaluation technique. Among these, the analysis of electric bioimpedance vectors (BIVA) has been recognized as a simple and promising method with high reproducibility. OBJECTIVE: To use BIVA to improve dry weight estimation in patients with chronic renal failure undergoing hemodialysis. Methods: This is a non-randomized pre-test / post-test clinical trial, where the universe of patients comes from the hemodialysis unit of the General State Hospital of Sonora. Patients who have limb amputations, pacemakers, metal implants, who are under renal transplant protocol or who have a renal transplant, and presence of infectious foci will be restricted from participating. The diagnosis of DW in the patients will be performed for modification and follow-up. Fluid status will be evaluated using BIVA. Measurements will be made before and after HD in three consecutive weekly periods and one one final assessment at three months. At the beginning of each period, weight, electrolytes, creatinine, total proteins, albumin, pre-albumin, urea and blood pressure will be measured to calculate the Malnutrition Inflammation Score and Bilbrey Index. At the end of the HD protocol of each period, body composition and muscle strength will be evaluated through triceps skinfold, mid-upper arm circumference and dynamometry. The dialysis dose received will be modified according to BIVA. The main variables to be considered will be DW, extracellular water and blood pressure. The duration of the study will be approximately 6 months. In addition, at the end of each measurement, each participant will be given a nutritional recommendation (feeding guide) specific to their energy requirements.
