Strategies to reduce sugar-sweetened beverages (SSB) have become one of the leading public health targets to address the epidemics of obesity and diabetes. National food, nutrition, and health policies and programs have positioned low-fat milk as the preferred caloric replacement strategy for SSBs. This strategy derives from evidence that replacement of SSBs with low-fat milk is associated with reductions in weight and incident diabetes in prospective cohort studies and reduces liver fat (an important early metabolic lesion linking obesity to diabetes), as well as triglycerides and blood pressure in randomized trials. Whether these benefits hold for soy milk alternatives is unclear. There is an urgent need for studies to clarify the benefits of soy milk as an alternative to cow's milk. Our overarching aim is to produce high-quality clinical evidence that informs the use of soy as a "public health intervention" for addressing the dual epidemics of obesity and diabetes and overall metabolic health. To achieve this aim, we propose to conduct the Soy Treatment Evaluation for Metabolic health (STEM) trial, a large, pragmatic, randomized controlled trial to assess the effect of using 2% soy milk (soy protein vehicle) versus 2% cow's milk (casein and whey vehicle matched for protein and volume) as a "public health intervention" to replace SSBs on liver fat and key cardiometabolic mediators/indicators in an at risk population.
Oat fibre has been shown to lower cholesterol and may have cardioprotective effects. However, whether this translates to actual cardiovascular risk reduction is unclear, as there is a lack of controlled human trials. To address this uncertainty, the investigator proposes to use established cardiovascular disease risk scores, such as those recommended by the Canadian Cardiovascular Society and other clinical practice groups, to create composite risk scores in assessing future risk. The data on oat fibre will be collected through a systematic review of controlled trials, composite cardiovascular risk scores will be calculated for each eligible study, and meta-analyses will be conducted to assess the overall effect. The findings generated by this proposed knowledge synthesis will help improve the health of consumers through informing evidence-based guidelines and improving health outcomes by educating healthcare providers and patients, stimulating industry innovation, and guiding future research design.
Prosthetic paravalvular leaks (PVL) leading to heart failure and/or haemolysis can be treated by interventional cardiology or open-heart surgery. Predictors of clinical success of transcatheter closure remains little known and should be identified to help choose between these two options.Patient selection criteria for the best option are needed. The investigators aimed to identify predictors of clinical success after transcatheter PVL closure. Consecutive patients referred to 24 European centres for transcatheter PVL closure in 2017-2019 were included in a prospective registry (Fermeture de Fuite ParaProthétique, FFPP) and followed over 2 years
The purpose of this investigation is to see if the TRICENTO Valved Stent Graft implant reduces tricuspid regurgitation (TR) and improves the symptoms and quality of life in 15 participants with carcinoid heart disease, and who are not able to have a new valve via a surgical procedure.
Background: Illicit drug use is a growing issue in Europe and leading cause of acute cardiac events in patients admitted to intensive cardiac care units. Indeed, cardiovascular complications are one of the main causes of death due to illicit drug use. However, its prevalence in patients hospitalized in intensive cardiac care units is unknown. Objectives: This large multicenter prospective study will assess the prevalence of illicit drug use in consecutive patients hospitalized in intensive cardiac care units by urine drug assay. Eligibility: - Patient over 18 years old admitted to intensive Cardiac Care Unit (CCU) for any reason. - Without hospitalization for a planned interventional procedure. - Without hospitalization for more than 24 hours at any hospital facility before admission to the CCU. Design: - Multicentre cohort study with a prospective enrolment of all consecutive patients admitted to the CCU to assess the prevalence of illicit drug use in 40 centers throughout France. - Participants will be screened with a physical exam, medical history and addiction survey. - Participants will be screened for drug use by urine drug assay (NarcoCheck®, Kappa City Biotech SAS, Montluçon, France) and for tobacco by standardized exhaled carbon monoxide (CO) measurement with a CO-Check Pro device (Bedfont Scientific Ltd, Kent, UK). - Participants will be followed at 6 months of follow-up to assess the occurrence of cardiovascular events.
The DIAST-CMD registry (Prognostic Impact of Cardiac Diastolic Function and Coronary Microvascular Function) is prospective registry which enrolled patients who underwent echocardiography, cnically-indicated invasive coronary angiography and comprehensive physiologic assessments including fractional flow reserve (FFR), CFR, and IMR measurements for at least 1 vessel from Samsung Medical Center. Patients with hemodynamic instability, severe LV dysfunction (left ventricular ejection fraction<40%), a culprit vessel of acute coronary syndrome, severe valvular stenosis or regurgitation were excluded.
Selection of the appropriate administered activity for each patient's body habitus is very important to obtain diagnostic image quality. Current SPECT imaging guidelines suggest "…an effort to tailor the administered activity to the patient's habitus and imaging equipment should be made… [however] strong evidence supporting one particular weight-based dosing scheme does not exist." An increase in body weight leads to higher fractions of attenuated and scattered photons, resulting in lower quality PET images for a given injected activity. Weight-based tracer dosing is commonly recommended as a solution in whole-body PET imaging with F-18-FDG. In contrast, Rb-82 PET imaging has traditionally been performed using a single dose (e.g. 40 mCi) administered for all patients but this is known to result in lower count-density and image quality in larger patients. This effect can be mitigated to some degree by administration of Rb-82 activity as a proportion of body weight while maintaining accuracy for the detection of disease. The objective of this project is to determine whether Rb-82 activity administered as a squared function of patient weight (quadratic dosing) can standardize PET myocardial perfusion image quality over a wide range of body weights. Sequential patients referred for dipyridamole stress Rb-82 PET perfusion imaging at the University of Ottawa Heart Institute. Patients will be divided into 4 weight groups to determine if there are significance differences in image quality or accuracy of injected Rb-82 activity between patients. Twelve (12) patients will be recruited in each of the 4 weight groups (3 in each 10 kg interval) to uniformly sample the full range of patient weights from 30 to 190 kg. Based on the previous oncology PET literature image quality is not expected to change as a function of weight, i.e. SNR and CNR will be proportional to weight0 (no weight-dependence) with quadratic dosing of Rb-82. Two operators will perform the PET image analysis as described above.
PROTEUS is a multicentre, two arm, randomised controlled trial of a medical device to assess the impact of the introduction of EchoGo into the standard care pathway for stress echocardiology.
Based on the clinical data of patients, a machine learning model for coronary heart disease diagnosis was established to evaluate whether the model could improve the accuracy of coronary heart disease diagnosis, and to evaluate its authenticity, reliability and benefits.
