Ethiopia is experiencing the type of rapid food system transformation that leads to a double burden of malnutrition and increased non-communicable diseases. Front-of-pack labels on packaged foods are an emerging public health strategy with the potential to address non-communicable diseases by discouraging the purchase and consumption of products with high levels of nutrients of public health concern. The aim of this study is to evaluate and compare the effectiveness of front-of-pack labeling systems to reduce the intent to purchase unhealthy foods among adults in Ethiopia. The study will recruit approximately 1200 adults using a street-intercept methodology. Participants will be randomized to 1 of 4 arms to complete a survey in which the presence and type of front-of-pack label differs across survey arms and asked to rate participants' intent to purchase unhealthy packaged foods.
This study aimed to discuss the correlation between interdialytic weight gain and cardiovascular diseases in children with end-stage kidney disease undergoing chronic hemodialysis. The cardiovascular parameters used include left ventricular hypertrophy, systolic and diastolic function, carotid intima-media thickness, myocardial circumferential strain, and strain rate.
Surgical coronary bypass surgery (CABG) has been demonstrated to confer significant survival benefit over medical therapies patients with LMCA in earlier clinical trials1,2,3 and therefore was the revascularization modality of choice for a long time. Recently, several randomized controlled trials and meta-analyses have shown percutaneous coronary intervention (PCI) to be non-inferior to CABG in the treatment of LMCA disease4,5,6,7,8. PCI is now considered to be an appropriate alternative to CABG for LMCA disease in patients with suitable anatomy9,10. Over recent decades, LMCA PCI has been performed in patients with increasing anatomical complexity and higher risk profiles (e.g. elderly, heart failure, renal failure etc). 11,12. In recent years, remarkable advancement in interventional techniques and technologies such as 2nd/3rd generation DES and potent antiplatelet therapy have contributed to the improvement of PCI success rates and reduction in complications and adverse events. Knowledge related to long term temporal variation of clinical and procedural characteristics and outcomes in patients with LMCA disease treated with PCI will therefore be important to inform and define future treatment strategies. This proposal aims to evaluate time-trends and regional differences in clinical characteristics and outcomes of patients with LMCA disease treated with PCI in the Asia-Pacific region
This study aims to obtain data on the potential influence of Vine to Bar product(s) containing Chardonnay marc on cardiometabolic health. These initial studies will inform the design and timing of data collection for future dietary intervention trials that will examine the influence of Chardonnay marc intake on outcomes/biomarkers of both cardiometabolic health and the gut microbiome. This includes collecting data on the potential differences in response to the products based on the unique food matrix for each of the products that will be tested. Moreover, as there is a paucity of data on the influence of cocoa flavanol intake on vascular function beyond 4 hours post intake, the response of the selected outcomes will be assessed after 6 hours of flavanol intake. This is a time point that captures the increased circulating presence of microbial derived flavanol metabolites.
The NITRATE-OCT:- Contrast Nephropathy Sub-study is a proof-of concept single center, randomized, clinical trial designed to ascertain whether a dietary NO3- approach might prove useful adjunctive therapy improving renal function and reducing CIN in patients with stable angina undergoing elective angioplasty. Objectives: To determine whether dietary NO3- ingestion exerts any effect on the glomerular filtration rate (GFR) after the exposure to contrast media. To determine if dietary NO3- ingestion will decrease the incidence of contrast induced nephropathy. Setting: The patients will be recruited from an on-going clinical trial NITRATE-OCT. This is a study assessing whether the use of dietary NO3- may reduce the incidence of restenosis following elective angioplasty. This study is recruiting patients with stable angina and single/multiple coronary artery stenosis undergoing elective PCI who are haemodynamically stable (systolic BP>100 mmHg). These patients will be recruited at The Barts Heart Centre at St Bartholomew's Hospital. This is one of the biggest centres in the UK, serving a population of almost two million people from The City of London and The North East up to the M25 and is a 24/7 centre performing approximately 3000 angioplasties a year. The study will take place in the Clinical Trials Unit, William Harvey Heart Centre. Target population: A total of 246 patients (male and female, age 18-85) with stable angina as per requirements indicated above. Follow-up will take place in the Clinical Trials Unit, William Harvey Research Institute. Treatment: Patients will be randomised (using an on line randomisation database) to receive 70 ml of a beetroot juice concentrate containing 4-5 mmol nitrate or nitrate-depleted placebo juice concentrate. This intervention will be taken by the patient daily from one day prior to re-establishment of flow with PCI and stent implantation.
This study is aimed to investigate the changes in pharmacokinetics and efficacy of antiplatelet agents before and after distal gastrectomy in gastric cancer patients taking oral antiplatelet agents for primary or secondary treatment for cardiovascular disease and to evaluate its impact on the occurrence of postoperative bleeding complications and thromboembolic events.
Background. Atherosclerotic cardiovascular disease (ACVD) comprising coronary disease, cerebrovascular disease, peripheral artery disease, and aortic atherosclerosis caused 8.9 million deaths worldwide according to reports submitted by the World Health Organization during 2019, the development and progression of atherosclerosis is favored in the presence of modifiable risk factors such as dyslipidemia. In Mexico, during the period from December 29, 2019, to August 29, 2020, 141,873 deaths from heart disease were reported, even above the 108,658 deaths from SARS COV2 in the same time period. Although it is known that the Mexican mestizo population is susceptible to certain metabolic lipid disorders related to genetic variants, the frequency of dyslipidemia in patients with high cardiovascular risk is unknown to date and may be responsible for this increase. On the other hand, it has been shown that lowering LDL-C levels in this population by means of the pharmacological or dietary treatment stated the current guidelines, decreases chance of death, heart failure, angina, re-infarction or need for coronary revascularization; however, there are still patients not achieving treatment goals. Consequently, it is suggested that through the implementation and correct use of technological tools it is possible to increase efficiency in the medical follow-up of patients, allowing for appropriate lipid levels, like other chronic degenerative diseases such as diabetes and systemic arterial hypertension. Objective. To describe the frequency of dyslipidemias in high-risk and very high-risk patients with atherosclerotic cardiovascular disease, who are IMSS beneficiaries, and to analyze the impact of using an application to achieve dyslipidemia treatment goals at one-year follow-up. Hypothesis For the National Register: Not required since the main objective is to carry out a national register of dyslipidemias. For the use of the application: Null hypothesis: The use of the application does not change the frequency of patients with high and extremely high atherosclerotic cardiovascular risk who achieve the goals of dyslipidemia treatment during one year of follow-up.
Fenofibrate, a peroxisome proliferator-activated receptor-alpha (PPAR-a) agonist known to improve diabetic dyslipidemia, has been proposed as a drug to prevent cardiovascular disease (CVD) in type 2 diabetes (T2D). However, the results of clinical trials have been mixed. Supporting the hypothesis that these disappointing results hide a genetic heterogeneity in the CVD response to fenofibrate, a common genetic variant (rs6008845) in the gene coding for PPAR-a has been found to dramatically influence the ability of this drug to reduce CVD events in the ACCORD Lipid trial (PMID:31974142). The aim of this study is to validate these findings by dissecting the pathways and mechanism through which this variant exerts such a modulatory effect, by means of a randomized clinical trial. If successful, this project will pave the way to a precision medicine approach to prescribe fenofibrate optimally, offering a cardio-protective drug to those patients that are most likely to experience a robust benefit from this medication.
The majority (>80%) of strokes are of ischemic etiology, of which ≈15% to 20% are attributable to atherosclerosis of the extracranial carotid arteries. The primary goal in carotid artery revascularization is to prevent stroke in patients with carotid artery stenosis. Treatment options including carotid endarterectomy (CEA) and carotid artery stenting (CAS). Hence, the investigators aim to compare carotid artery stenting (CAS) with carotid endarterectomy (CEA) in terms of long-term prognostic endpoints. Also, CEA and CAS result in different postoperative geometric features of carotid arteries that entail relevant modifications of rheological parameters, that may be associated with the risk of local complications and carotid artery restenosis. Finally, long-term and sustained cognitive benefits after carotid artery revascularization need further research and evidence.
