Filter by:The Military Health and Nutrition Examination Study (MHANES) is a Department of Defense funded study conducted by Pennington Biomedical Research Center and the US Army Research Institute of Environmental Medicine. This cross-sectional study will assess, in a large, diverse sample of Army Service Members (n=600), food and supplement intake, cardiovascular health, body composition, biomarkers of nutritional status, measures of health status, injury prevalence, mental wellbeing, gut microbiome composition, and physical performance outcomes. The proposed study is modeled after the National Health and Nutrition Examination Survey (NHANES) and customized for the Army population.
The aim of our proposed program is to develop and implement a multilevel, multicomponent and health-financing intervention that will facilitate the scale up of evidence-based strategies to improve non-communicable diseases prevention, detection and control in Tanzania. We will accomplish this by: 1) adapting two intervention components that are candidates for inclusion in a highly effective optimized strategy (called STOP-NCDs) and; (b) Assess their individual and combined effectiveness and 2) conducting a robust, mixed-methods evaluation of the implementation process and assess factors that may influence implementation and sustainability for delivering and scaling the optimized STOP-NCDs strategy. We will select and/or adapt intervention components making up the optimized STOP-NCDs strategy. Using a hybrid clinical-effectiveness implementation design, we will conduct a study in 2 sequential phases: 1) A clinical-effectiveness phase in which we evaluate the effect of our combined strategies (task-sharing and WelTel) versus Usual Care, on rates of systolic BP reduction at 12 months; as well as other secondary outcomes including diagnosis and treatment of diabetes and, patient knowledge of CVD risks and prevention, and, other features of health provider NCD prevention activities. 2) A post-implementation phase in which we use the RE-AIM framework to evaluate changes in the adoption and maintenance of our combined strategies in participating iCHF health facilities across Kilimanjaro region. We will use the WelTel communication and Patient Management platform for to deliver culturally and contextually appropriate evidence-based text messaging to patients. It allows for quality improvement and is a unique tool for our program to scaling low-cost interventions that provide capabilities for tracking of health system service uptake, quality-metrics at health facilities, drug stock-out management, and patient-centered behavioral health interventions. Deployment of WelTel will allow for integration of NCD prevention targeted health services to all adult iCHF members across differing life stages and NCD risk and have a significant impact on increasing quality of care and sustainability of health financing and performance-based incentives through improved prescribing, patient engagement, medication adherence and healthy behaviour change.
This study will test the effects of a physical activity intervention among midlife Hispanic women.
Nitric Oxide (NO) is an important molecule that is produced naturally in the body and that helps maintain healthy blood flow. Low availability of NO contributes to many diseases while administration of NO is therapeutic. In addition to being made naturally in the body, NO can be obtained through the diet via the Nitrate-Nitrite-NO cycle. Nitrate, which is abundant in green leafy vegetables and beetroot juice, is partially converted to nitrite by oral bacteria. The nitrate and nitrite are taken up into the blood and nitrite is converted into NO. Remaining nitrate in the blood is taken back up into the mouth by salivary glands and the cycle continues. Emerging studies suggest that the Nitrate-Nitrite-NO cycle may contribute to cardiovascular health. In addition, there have been many studies where dietary nitrate is given to increase NO and treat various conditions. The current study rests on the premise that the quality of the oral microbiome plays a major role in the Nitrate-Nitrite-NO cycle and hence cardiovascular health and the efficacy of dietary nitrate interventions. Investigators have begun to identify oral bacterial species that are effective nitrite producers as well as though that are nitrite depleters (those that interfere with nitrite production from nitrate). In laboratory experiments, certain bacterial species have been shown to block nitrate to nitrite conversion by other oral bacteria. These nitrite depleting species are found in a commercially available oral probiotic designed to improve oral health. The purpose of this study is to examine if use of the probiotic negatively affects the Nitrate-Nitrite-NO cycle. Nitrate to Nitrite conversion will be assessed by measuring plasma levels of nitrite before and after consumption of nitrate-rich beetroot juice. Dietary nitrate to plasma nitrite conversion will assessed at baseline and after one week of consumption of the probiotic or a placebo (follow-up). The primary hypothesis of this study is that participants that consume the probiotic will have lower nitrate to nitrite conversion at follow-up compared to baseline and that there will be no significant change in nitrate to nitrite conversion between baseline and follow-up for participants who consume the placebo. While this study does not aim to treat any specific disease, it is intended to elucidate a basic physiological function that may be relevant to cardiovascular health and certain NO-based therapeutics.
Around 50% of infants born extremely preterm develop a chronic lung disease known as bronchopulmonary dysplasia of which some infants will also develop pulmonary hypertension of which 50% of children will die before the age of 2. Physicians are currently limited in their ability to select the most appropriate oxygen targets that will improve outcomes in infants with this condition. This clinical trial will determine whether using different amounts of oxygen improve outcomes in infants with this disease.
This study is a multi-centre, non-interventional, observational, prospective study with retrospective analysis. The main purpose of the study is to describe the rate of CKD diagnosis in patients with AH and CKD markers. This study will include 10 000 adult outpatients with arterial hypertension, who have one or more Chronic Kidney Disease laboratory markers (without recorded CKD diagnosis prior to enrolment) and have no diabetes mellitus or chronic heart failure, who are monitored and treated by cardiologists or internal medicine specialists in approximately 50 outpatient sites in about 20 regions in Russia. This observational study does not provide for any diagnostic and therapeutic procedures other than those used in routine practice.
The present study, OBPM_Calfree2024, with N = 85 participants minimum over 1 visit (lasting around 1h), has been designed to evaluate the performances and safety of the Aktiia.product-G2C that doesn't require any calibrations, as compared against double auscultation for BP reference measurements, and finger pulse oximeter for pulse rate reference measurements, for a cohort of subjects characterized by a wide variety of phenotypes.
The goal of this implementation science study is to design evidence based and stakeholder informed implementation strategies to integrate the management of hypertension (HTN) into existing community anti-retro-viral treatment (ART) delivery models of HIV care in Uganda and evaluate their effectiveness and implementation outcomes. The main questions it aims to answer are: 1. What are the perspectives of patients (hypertensive PLHIV) on integrating hypertension care in community ART delivery models of HIV care? 2. What are the perspectives of health care providers', district leaders', and policymakers' perspectives on integrating hypertension care in community ART delivery models of HIV care? 3. What implementation strategies would support integration of the management of hypertension into existing community ART delivery models in Uganda? 4. What is the effectiveness of implementation strategies to integrate the management of hypertension care in community ART delivery models of HIV care in Uganda? 5. What are the implementation outcomes of strategies to integrate hypertension care in community ART delivery models of HIV care in Uganda? 6. What is the cumulative incidence, types and severity of HTN medication-related adverse events and their predictors among PLHIV with HTN? Investigators will use qualitative research methods to explore key stakeholders' perspectives and preferences on integrating hypertension care in community ART delivery models in Uganda; design implementation strategies that integrate the management of hypertension into existing community ART delivery models; determine the effectiveness of implementation strategies that integrate the management of hypertension in community ART delivery models; evaluate implementation outcomes of strategies that integrate hypertension care in community ART delivery models; determine the cumulative incidence, types and severity of medication-related adverse events and their predictors; and assess the patients and provider costs, health related quality of life, cost-effectiveness of leveraging existing HIV differentiated service delivery models to screen and treat HTN among persons with HIV in Uganda.
The goal of this pilot clinical trial is to evaluate a culturally tailored computerized education program in hospitalized African-American patients with advanced chronic kidney disease (CKD). The main question it aims to answer are: does computerized adaptive education (CAE) increase patients' knowledge about CKD self-care and renal replacement therapy (RRT) options compared to usual care (UC) and will CAE will be increase patients' intent to participate in CKD self-care and RRT preparation compared to UC
The investigators long-term goal is to better understand novel interventions to promote cardiovascular health in humans. The goal of the proposed research is to investigate whether there is sex-specificity in the effects of dietary capsaicin on mechanisms regulating nitric oxide (NO) bioavailability, its effect on key markers of cardiovascular (CV) health, including BP, macro- and microvascular function, and arterial stiffness. This knowledge will provide critical insight into the effects of dietary capsaicin on CV health and will guide future trials.
