Effect of an educational program in primary care: the case of lipid control in cardio-cerebrovascular prevention.
2014
Lowering blood cholesterol levels reduces the risk of coronary heart disease. However, the effect of interventions depends on the patients' adherence to treatment. Primary care plays an important role in the detection, treatment and monitoring of disease, therefore different educational programs (EP) have been implemented to improve disease management in general practice. The present study is aimed to assess whether a general practitioner auditing and feedback EP may improve dyslipidaemia management in a primary care setting and to evaluate patients' adherence to prescribed lipid-lowering treatment. The quality of cardiovascular and cerebrovascular disease prevention before and after the i…
Effects of statins on lipid profile in chronic kidney disease patients: a meta-analysis of randomized controlled trials
2013
The available data on statin effects in chronic kidney disease (CKD) patients are still conflicting. We investigated the impact of short- and long-term statin therapy on lipid profiles in CKD patients requiring or not requiring dialysis.Data from Scopus, PubMed, Web of Science, and the Cochrane Library from 1966 to May 2012 were searched for studies that investigated this effect. We included all randomized controlled clinical trials that investigated the impact of statin therapy on lipids and lipoproteins.The final analysis included 16 trials with 3594 subjects. In CKD patients, statin therapy significantly reduced total cholesterol (TC), triglycerides (TG) and low-density lipoprotein chole…
Dietary (n-3) polyunsaturated fatty acids exert antihypertensive effects by modulating calcium signaling in T cells of rats.
2001
After 10 wk of feeding an experimental diet enriched with (n-3) polyunsaturated fatty acids (PUFA), i.e., eicosapentaenoic acid [EPA, 20:5(n-3)] and [DHA, 22:6(n-3)] (EPAX), blood pressure in spontaneously hypertensive rats (SHR), but not in normotensive Wistar-Kyoto (WKY) rats was reduced relative to rats fed an unsupplemented control diet. Concanavalin A-stimulated T-cell proliferation was diminished in both strains of rats fed the PUFA/EPAX diet. The experimental diet lowered secretion of interleukin-2 in SHR, but not in WKY rats compared with rats fed the control diet. To determine whether there was a defect in calcium homeostasis in T cells during hypertension, we employed the followin…
Cardiovascular Risk in Young Finns
1991
This report describes the general outline and progress of a multicentre study on risk factors of coronary heart disease and their determinants in children and adolescents. "Cardiovascular Risk in Young Finns" comprises a cross-sectional study of 3 to 18-year old subjects in 1980, and follow-up studies in 1983 and 1986 in various parts of Finland, and in 1989 in one of the study areas (Turku). The number of participants in 1980 was 3596 (83.1%) of those invited. In 1983 and 1986 83.2% and 77.8% of them, respectively, participated. The study programme has comprised questionnaire data on, for example, general health and living conditions, physical activity, eating habits, smoking, and psycholo…
Impact of Accessory Renal Artery Coverage on Renal Function during Endovascular Aortic Aneurysm Repair.
2021
Background Long-term outcomes of accessory renal artery (ARA) coverage after endovascular aneurysm repair (EVAR) are unknown. We analyzed the impact of ARA coverage on renal function long-term. Methods This retrospective, monocentric study included patients treated by EVAR between 2008 and 2016. Patients with at least one ARA covered with EVAR (ARA group) were compared with patients with no covered ARA (control group). Renal function was determined by estimating the glomerular filtration rate (eGFR) and graded according to chronic kidney disease (CKD) classification stages. Results A total of 184 patients were included (ARA group, n = 25; control group, n = 159). Renal risk factors were sim…
Dietary fat intake and risk of cardiovascular disease and all-cause mortality in a population at high risk of cardiovascular disease.
2015
Background Dietary fat quality and fat replacement are more important for cardiovascular disease (CVD) prevention than is total dietary fat intake. Objective The aim was to evaluate the association between total fat intake and fat subtypes with the risk of CVD (myocardial infarction, stroke, or death from cardiovascular causes) and cardiovascular and all-cause death. We also examined the hypothetical effect of the isocaloric substitution of one macronutrient for another. Design We prospectively studied 7038 participants at high CVD risk from the PREvencion con DIeta MEDiterranea (PREDIMED) study. The trial was conducted from 2003 to 2010, but the present analysis was based on an expanded fo…
Effect of aqueous extract of Ajuga iva supplementation on plasma lipid profile and tissue antioxidant status in rats fed a high-cholesterol diet
2006
Abstract The present study was designed to explore the possible antioxidant and hypolipidemic effects of the aqueous extract of Ajuga iva (0.5% in the diet) in rats fed a high-cholesterol (1%) diet (HCD). The results indicated that the HCD-Ai versus HCD treatment led to many changes in biochemical parameters. They showed a decrease of plasma total cholesterol (TC) and VLDL-cholesterol but an increase of HDL2-cholesterol. The triacylglycerol contents were reduced in plasma and in VLDL. The lipid peroxidation determined by TBARS was decreased by 75% in plasma. TBARS in liver, heart and kidneys were highly reduced excepted in the adipose tissue. Ajuga iva treatment enhanced superoxide dismutas…
Reduction in systemic and VLDL triacylglycerol concentration after a 3-month Mediterranean-style diet in high-cardiovascular-risk subjects.
2010
The first results of the PREDIMED (PREvencion con Dieta MEDiterranea) randomized trial, after 3-month intervention, showed that the Mediterranean Diet (MD), supplemented with either virgin olive oil (VOO) or nuts, reduced systolic blood pressure, serum cholesterol and triacylglycerol (TG) concentrations and increased high-density lipoprotein (HDL)-cholesterol when compared to a control (low-fat diet) group. Serum TG levels are an independent risk factor for coronary heart disease and are strongly determined by very low-density lipoprotein (VLDL) composition, which can be specifically modified by dietary lipid source. Within the context of the PREDIMED study, we assessed the VLDL composition…
Hepatic storage and transport of n-3 and n-6 polyunsaturated fatty acids by very-low-density lipoproteins in growing rats fed low- or adequate-protei…
1997
Protein and essential fatty acid (EFA) deficiencies may both occur in chronic malnutrition and have common symptoms. To determine the interactions between dietary protein intake and EFA availability, rats were fed purified diets containing 20% or 2% casein and 5% as one of four fats (sunflower, soybean, coconut, or salmon oil) that differed particularly in their n-6 and n-3 polyunsaturated fatty acids (PUFAs). Protein malnutrition enhanced hepatic triacylglycerol and cholesterol concentrations while decreasing hepatic protein and phospholipid contents and mass and components of very-low-density lipoprotein (VLDL). The ratio of PUFAs to saturated fatty acids (SFAs) was consistently depressed…
Dietary protein deficiency affects n-3 and n-6 polyunsaturated fatty acids hepatic storage and very low density lipoprotein transport in rats on diff…
1994
Fatty livers and the similarity between the skin lesions in kwashiorkor and those described in experimental essential fatty acid (EFA) deficiency have led to the hypothesis that protein and EFA deficiencies may both occur in chronic malnutrition. The relationship between serum very low density lipoprotein (VLDL) and hepatic lipid composition was studied after 28 d of protein depletion to determine the interactions between dietary protein levels and EFA availability. Rats were fed purified diets containing 20 or 2% casein and 5% fat as either soybean oil rich in EFA, or salmon oil rich in eicosapentaenoic (EPA) and docosahexaenoic (DHA) acids, or hydrogenated coconut, oil poor in EFA. Animal…
