NCT ID: NCT03490695 Active, not recruiting - Hypertension Clinical Trials

Uptake of Task-Shifting for Blood Pressure Control

Start date: September 1, 2017
Phase: N/A
Study type: Interventional

Uptake of a community-based evidence-supported interventions for hypertension control in Ghana are urgently needed to address the cardiovascular disease epidemic and resulting illness, deaths, and societal costs. This study will evaluate the effect of Practice Facilitation on the uptake and maintenance of the evidence-based task-shifting strategies for hypertension control (TASSH) protocol across 70 Community-based Health Planning and Services (CHPS) zones delivered by trained community health officers. Findings from this study will provide policy makers and other stakeholders the "how to do it" empirical literature on the uptake of evidence-based interventions in Ghana, which may be applicable to other low-income countries.

NCT ID: NCT03373357 Active, not recruiting - Clinical trials for Hypertension Arterial

Hypertension and Cardiovascular Risk Associated With Obstructive Sleep Apnea in Adult in Guadeloupe (French West Indies)

Start date: September 9, 2008
Phase: N/A
Study type: Interventional

The MAPA is the reference method to estimate the PA during the SAHOS. The MAPA can be recommended over 48 hours: indeed, the PA falls at the beginning of every apnea then increases gradually up to a pressif peak arising at the time of the ventilatoire resumption. These variations arise under the influence of 4 stimulus: the désaturation in O2, the rise of the PaCO2, the increase of the respiratory effort and the microawakening of the end of apnea who are at the origin of a sympathetic stimulation. Consequently a better diagnostic approach of the HTA (confirmation of a resistant HTA, an identification of the masked HTA and the patients " not dipper " by the MAPA), the identification of the SAHOS, and a better coverage) of the associated cardiovascular risk factors are essential and establish a stake in public health. To investigator's knowledge, no datum or study on the association HTA-SAHOS and its consequences was until then realized in the French overseas departments.

NCT ID: NCT03369496 Active, not recruiting - Obesity Clinical Trials

The Montreal Neighbourhood Networks and Healthy Aging Panel

Start date: July 1, 2007
Phase: N/A
Study type: Observational

Social networks, social capital, i.e., network-accessed resources, and neighbourhood environments have been shown associated with a range of health behaviours and conditions, including obesity, physical activity, nutrition, and mental health. Research on social capital and health in Montreal has shown the importance of network social capital for a person's subjective health status, sense of control, self-reported physical activity, and obesity. Research has also shown high social capital to reduce health service use, mental health service use, and improve the management of chronic illnesses. Despite advances in the understanding of social capital and its link to health and health service use, most research on social capital is cross sectional and is unable to identify the causal pathways linking social networks and capital to health and health care use. Longitudinal research would strengthen the evidence base for designing interventions to prevent or delay the use of health services, particularly in older adults. This research has three main objectives: (1) transform the original sample of Montreal Neighbourhood Networks and Healthy Aging (MoNNET-HA) households (n=2707) into a panel study, (2) link the MoNNET-HA participant data to their Quebec Health Insurance Registry (Régie de l'assurance maladie (RAMQ)) information, and (3) assess the feasibility of extending the MoNNET-HA panel by one wave to include participant's core network members. Unique about the original MoNNET-HA sample is that it purposefully oversampled older adults (> 64 years old) but remains representative of Montreal adults at various ages and income levels. In addition, MoNNET-HA data is integrated into a GIS database which allows researchers to examine the effects of neighbourhood environmental characteristics on health. By linking MoNNET-HA data to RAMQ, researchers will be able to examine patterns of diagnosed health conditions, (e.g., fractures, depression), pharmaceutical use and adherence, and formal health care use over time. Transforming the cross-sectional study into a panel study would also allow researchers to examine longitudinally the dynamics of health and health care utilization among Panel participants over the life course, and the causal pathways linking neighbourhoods and networks to health and health care use.

NCT ID: NCT03314012 Active, not recruiting - Clinical trials for Hypertension,Essential

First-In-Human Study Evaluating a Novel Catheter Device in Subjects With Treatment-Resistant Hypertension

Start date: December 11, 2015
Phase: N/A
Study type: Interventional

The carotid body is located at the bifurcation of the internal and external carotid arteries. It is a chemoreceptor that plays a role in the sympathetic nervous system and in the development and maintenance of hypertension. Hypertension is a major cardiovascular risk factor and is associated with coronary artery disease, stroke, chronic kidney disease, and heart failure. The objective of this study is to assess the effectiveness and safety of a catheter-based system to ablate the carotid body and reduce blood pressure (BP) in patients with resistant hypertension and to confirm sustainability of the treatment benefits long-term as seen following surgical CB removal.

NCT ID: NCT03301194 Active, not recruiting - Hypertension Clinical Trials

Cost-effectiveness of RAMP-HT for Patients With Uncontrolled Hypertension in Hong Kong

Start date: August 1, 2016
Study type: Observational

Hypertension (HT) is an important risk factor for stroke, coronary heart disease (CHD), heart failure and renal diseases, and the leading risk factor of global disease burden. A multitude of interventions have proven efficacy in lowering blood pressure and reducing long term HT complications, including pharmacologic treatment, DASH diet (Dietary Approaches to Stop Hypertension), exercise, weight reduction, smoking cessation, alcohol moderation and self-monitoring of blood pressure. Objectives: To evaluate long-term effectiveness and cost-effectiveness of Risk-Assessment-and-Management-Programme-for-Hypertension (RAMP-HT), a multi-disciplinary structured service to enhance quality of hypertension care in primary care compared to usual care Hypotheses: 1. RAMP-HT is effective in reducing HT complications, based on previous results showing RAMP-HT was effective in improving patients' blood pressure 2. RAMP-HT is cost-effective Design and Subjects: Retrospective study of 5-year longitudinal data on matched cohorts of public primary care patients with uncontrolled HT under RAMP-HT and usual care will be conducted to evaluate long-term effectiveness and direct medical costs. Results from the long-term effectiveness and costing analyses will be applied to Markov modeling to determine the life time cost-effectiveness of RAMP-HT. Main outcome measures: 1. 5-year incidence of cardiovascular complications 2. Direct medical costs of RAMP-HT and usual care HT patients 3. Incremental cost-effectiveness ratio (ICER) of cost per quality-adjusted life year (QALY) gained by RAMP-HT compared to usual care Data analysis: Cox regression will be performed to estimate the effect of RAMP-HT on the development of HT complication adjusted for baseline covariates. Descriptive statistics will be used to calculate costs of RAMP-HT and annual direct medical costs for HT patients. Markov modeling will be used to simulate 2 patient cohorts (RAMP-HT versus usual care) to estimate the respective lifetime direct medical costs and QALY gained/person. Cost/QALY of RAMP-HT will be compared to that of usual care to determine the ICER. Expected results: The results can provide evidence on the effectiveness and cost-effectiveness of RAMP-HT for primary care patients with uncontrolled HT, which can inform health policy and service planning.

NCT ID: NCT03296332 Active, not recruiting - Hypertension Clinical Trials

Shandong and Ministry of Health Action on Salt and Hypertension Project

Start date: January 2011

NCT ID: NCT03285230 Active, not recruiting - Breast Cancer Clinical Trials

The French E3N Prospective Cohort Study

Start date: June 15, 1990
Phase: N/A
Study type: Observational

The French E3N cohort was initiated in 1990 to investigate the risk factors associated with cancer and other major non-communicable diseases in women. The participants were insured through a national health system that primarily covered teachers, and were enrolled from 1990 after returning baseline self-administered questionnaires and providing informed consent. The cohort comprised nearly 100 000 women with baseline ages ranging from 40 to 65 years. Follow-up questionnaires were sent approximately every 2-3 years after the baseline and addressed general and lifestyle characteristics together with medical events (cancer, cardiovascular diseases, diabetes, depression, fractures and asthma, among others). The follow-up questionnaire response rate remained stable at approximately 80%. A biological material bank was generated and included blood samples collected from 25 000 women and saliva samples from an additional 47 000 women. Ageing among the E3N cohort provided the opportunity to investigate factors related to agerelated diseases and conditions as well as disease survival.
