Filter by:The European Prospective Investigation into Cancer and Nutrition in Norfolk is a population based prospective study of approximately 25,000 men and women resident in Norfolk United Kingdom. They were aged 39-79 years when first recruited from general practice age sex registers at baseline assessment 1993-1997. While part of a ten country half million participant European collaboration originally aimed to investigate diet and other lifestyle determinants of cancer, the objectives of the Norfolk cohort from inception were expanded to encompass the trajectory of health, ill health and mortality in a population over time and to examine the biological and lifestyle determinants of health and chronic disease.
This study aims to demonstrate that the BioFreedom™ Cobalt Chromium Drug Coated Stent is non-inferior to the market authorized BioFreedom™ Stainless Steel Stent with respective to efficacy and shows a similar safety profile.
Fabry disease (FD) is a genetic disorder that leads to progressive accumulation of fat or 'sphingolipid' within the tissues, including the heart muscle and conductive tissue. Improvements in the detection of FD, together with more organised clinical services for rare diseases, has led to a rapid growth in the disease prevalence. Earlier and more frequent diagnosis of asymptomatic individuals before development of the disease itself has focused attention on early detection of organ involvement and closer monitoring of disease progression. Moreover, the introduction of enzyme replacement therapy within the last two decades has changed the natural history of FD as follows: a) increased life expectancy; b) improved morbidity; c) modification of the main cause of morbidity and mortality from renal (kidney) to cardiovascular (heart) events, including heart failure, abnormal heart rhythms, stroke and sudden death. Although symptoms such as palpitations and blackouts are extremely common, information on the frequency of proven abnormal heart rhythms is limited. In addition, the rate and appropriateness of implantation of life-saving devices is very variable, including pacemakers to boost the heart when too slow and cardio-defibrillators that stop the heart when too fast. The main markers of risk in similar diseases such as hypertrophic cardiomyopathy cannot be used in FD. While patients are routinely followed up in clinic with heart tracings and echocardiography (ultrasound of the heart), a recent small study has emphasised that these tests under-estimate the burden of abnormal heart rhythms in patients with advanced FD. The use of continuous heart monitoring with an implantable loop recorder (ILR) has led to a significant change in treatment in 13 out of 15 of FD patients. The investigators believe that more frequent use of ILRs will identify a greater need for change in therapy in many more patients than currently treated, with the aim of reducing morbidity and mortality in this patient cohort. In addition this will provide valuable data to inform an estimate of future risk for these patients.
Short-term (1-year) results of renal transplantation are now excellent (over 95%). Long-term (10-year and longer) results are, however, still disappointing. Where most research has focused on immunosuppression and infections, the investigators hypothesize that in renal transplant recipient, amongst others overweight, obesity, chronic use of immunosuppressive drugs and impaired renal function contribute to insulin resistance and chronic low-grade inflammation, which pose the renal transplant recipients at increased risk for cardiovascular disease, decline of function of the transplanted kidney and other complications, including post-transplant diabetes. This study is a biobank and cohort study which investigates this hypothesis.

Purpose: The Guangzhou Nutrition and Health Study (GNHS) project aims to assess the determinants of metabolic disease in nutritional aspects, as well as other environmental and genetic factors, and explore possible mechanisms with multi-omics integration. Study design: GNHS is a community-based prospective cohort study. Participants: In this cohort, the original GNHS and another cohort study (the controls of a case-control study of hip fractures, CCFH) have been integrated into the one GNHS project. After completing the baseline examination, a total of 5118 participants were recruited during 2008-2015 in the GNHS project. Visits and Data Collection: Participants were/will be visited every three years by invited to the School of Public Health, Sun Yat-sen University. At each visit, face-to-face interviews, specimen collection, anthropometric measurements, dual-energy x-ray absorptiometry (DXA) scanning, ultrasonography evaluation, vascular endothelial function evaluation, cardiopulmonary exercise testing, magnetic resonance imaging (MRI), 14-d real-time continuous glucose monitoring tests, laboratory tests, and multi-omics data were/will be conducted. Up to December 2022, 3442 and 2895 subjects completed the 2nd and 3rd visits. Key variables: 1. Questionnaire interviews. 2. Physical examinations: Anthropometric measurements, blood pressure tests, handgrip strength, muscle function and bracelet motion monitoring. 3. DXA scanning: To determine bone density, bone mineral content, bone geometry information, fat mass, and muscle mass. 4. Ultrasonography evaluations: To determine carotid artery intima-media thickness and plaque, and fatty liver. 5. Vascular endothelial function evaluation. 6. Cardiopulmonary exercise testing: Lung function. 7. MRI: Brain and upper-abdomen MRI. 8. 14-d Real-time continuous glucose monitoring tests. 9. Specimen collections: Overnight fasting blood, early morning first-void urine, faces, and saliva samples. 10. Laboratory tests: Metabolic syndrome-related indices; Diabetes-related indices; Uric acid; Nutritional indices; Inflammatory cytokines; Index of oxidative stress; Adipocytes; Sexual hormones; Liver and renal function-related markers; Routine blood test. 11. Multi-omics data: Genotyping data; Gut microbiota; Untargeted serum and fecal proteomics; Targeted serum and fecal metabolomics. 12. Morbidity and mortality: Relevant data were/will be also retrieved via local multiple health information systems.
For the purpose of organ donation after neurological determination of death (NDD), death must be declared using a set of standardized clinical criteria. When a full clinical evaluation cannot be completed, additional neuroimaging ancillary testing is required. The ideal ancillary test for NDD would demonstrate no cerebral blood flow, be free of false-positive and false negative results, rapid, safe, readily available, non-invasive, and inexpensive. No current ancillary test for NDD meets these criteria. Computed tomography (CT) perfusion has the characteristics of an ideal test for NDD, but has not been evaluated for routine clinical use for NDD. The overarching goal of this project is to improve the NDD process by establishing CT-perfusion as the ideal ancillary test. A large prospective Canadian multi-centre diagnostic cohort study will be conducted to validate CT-perfusion for the neurological determination of death. Specific objectives are: Primary objective: To determine diagnostic accuracy of CT-perfusion compared to complete clinical evaluation for NDD. Secondary objectives: 1) To confirm the safety of performing CT-perfusion in critically ill patients suspected of being neurologically deceased; 2) To establish the CT-perfusion inter-rater reliability for NDD; 3) To evaluate the diagnostic accuracy of CT-angiography compared to complete clinical evaluation and to CT-perfusion for NDD; 4) To describe the clearance of commonly used sedatives and narcotics in the setting of NDD; and 5) to investigate biological changes (inflammatory and nanovesicles) that occur in humans during the brain dying process.
Primary objective of the study is to measure the impact of a comprehensive package of interventions introduced by the Safe Motherhood Promotion and Newborn Survival project on neonatal mortality in three Upazila of Chandpur district, Bangladesh
The Helsinki Businessmen Study (HBS) is a clinico-epidemiological longitudinal study started in 1964. It also included a 5-year randomized, controlled multifactorial primary prevention trial of cardiovascular diseases between 1974-1980. The cohort is being actively followed-up through national registers since the 1980, and since 2000 with regular questionnaire surveys. Latest in 2015. Also clinical and laboratory studies have been performed in random subcohorts. Follow-up is ongoing with new hypothesis-generating research questions.
The major objective is to demonstrate the safety and efficacy of ANG-3777 in improving graft function and reducing the severity of delayed graft function (DGF) in recipients at high risk of DGF after receiving a deceased donor renal allograft.
