Familial combined hypolipidemia due to mutations in the ANGPTL3 gene
2013
The role of ANGPTL3 in lipoprotein metabolism emerged from studies in a mutant mouse strain characterized by severe hypotriglyceridemia and carrying a loss-of-function (LOF) mutation of the ANGPTL3 gene. ANGPTL3 was found to inhibit lipoprotein lipase and endothelial lipase. Genome-wide association studies in humans demonstrated the association of ANGPTL3 variants with plasma triglyceride levels and LOF mutations of ANGPTL3 were found in hypotriglyceridemic subjects in population studies. Recently, individuals originally classified as affected by familial hypobetalipoproteinemia were found to be homozygotes/compound heterozygotes for rare LOF mutations of ANGPTL3. They show a striking reduc…
The reporting of previous lifestyle counseling by persons at high risk of Type 2 diabetes.
2011
Abstract Objective To assess (i) whether the reporting of counseling previously received is associated with high-risk individuals' agreement to participate in lifestyle intervention, (ii) whether the reporting of previous counseling differed within such a high-risk group, and (iii) the associations between lifestyles and previous lifestyle counseling. Methods Cross-sectional data were drawn from 10149 adults at high risk of Type 2 diabetes, who were participating in a Finnish national diabetes prevention project (FIN-D2D). Bivariate analysis and multivariate logistic regression were used. Results In relation to the reporting of previous counseling, no difference was found between persons wh…
Cardiovascular risk factors in centenarians"
2008
Several studies have shown that centenarians have better cardiovascular risk profiles compared to younger old people. Some reports have revealed that cardiovascular diseases (i.e. hypertension, diabetes, angina and/or myocardial infarction) are less common in centenarians respect to 70 and 80 years old persons. In order to explain this evidence, there is a growing number of hypothesis that consider a combination of genetic factors and lifestyle aspects to elucidate the exceptional longevity of centenarians, able to overcome the most frequent mortality cause, which is a cardiovascular event. It has been suggested that a role on this better cardiovascular risk profile may be played by the inc…
Adherence to a Mediterranean-type diet and reduced prevalence of clustered cardiovascular risk factors in a cohort of 3204 high-risk patients
2008
Background The Mediterranean food pattern (MeDiet) has been suggested to have beneficial effects on cardiovascular risk factors. Scarcity of assessment of this effect on large samples of patients at high risk is, however, observed. Our objective was to estimate the association between adherence to MeDiet and the prevalence of risk factors in 3204 asymptomatic high-risk patients. Design Cross-sectional assessment of baseline characteristics of participants in a primary prevention trial. Methods Participants were assessed by their usual primary-care physicians to ascertain the prevalence of diet-related cardiovascular risk factors (diabetes, hypertension, dyslipidemia, or obesity) using stand…
Cross-sectional assessment of nut consumption and obesity, metabolic syndrome and other cardiometabolic risk factors: the PREDIMED study
2013
INTRODUCTION: Prospective studies have consistently suggested that nut consumption is inversely related to fatal and non-fatal coronary heart disease. Limited data are available on the epidemiological associations between nut intake and cardiometabolic risk factors. OBJECTIVE: To evaluate associations between frequency of nut consumption and prevalence of cardiometabolic risk factors [obesity, metabolic syndrome (MetS), type-2 diabetes, hypertension, and dyslipidemia] in a Mediterranean population at high cardiovascular risk. MATERIALS AND METHODS: Cross-sectional study of 7,210 men and women (mean age, 67 y) recruited into the PREDIMED study. MetS was defined by the harmonized ATPIII and I…
An International Atherosclerosis Society Position Paper: global recommendations for the management of dyslipidemia.
2014
An international panel of the International Atherosclerosis Society has developed a new set of recommendations for management of dyslipidemia. The panel identifies non-high density lipoprotein cholesterol (non-HDL-C) as the major atherogenic lipoprotein. Primary and secondary prevention are considered separately. Optimal levels for atherogenic lipoproteins are derived for the two forms of prevention. For primary prevention, the recommendations emphasize lifestyle therapies to reduce atherogenic lipoproteins; drug therapy is reserved for higher risk subjects. Risk assessment is based on estimation of lifetime risk according to differences in baseline population risk in different nations or r…
LC-ESI/HRMS analysis of glucosinolates, oxylipins and phenols in Italian rocket salad (Diplotaxis erucoides subsp. erucoides (L.) DC.) and evaluation…
2021
BACKGROUND: This study investigated the chemical profile and biological activity of Diplotaxis erucoides subsp. erucoides (L.) DC. (Brassicaceae) collected in Sicily (Italy). RESULTS: Liquid chromatography coupled with electrospray ionization and high-resolution mass spectrometry (LC-ESI/HRMS) analysis of the ethanol extract revealed the presence of 42 compounds – glucosinolates, hydroxycinnamic acids, flavonoids, and oxylipins. The extract was tested for its antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH), 2,2′-azinobis(3-ethylbenzothiazoline-6-sulfonic) acid (ABTS), ferric reducing ability power (FRAP), and β-carotene bleaching tests. Promising protection from lipid peroxi…
Study of the ability of apolipoprotein C1 to inhibit cholesteryl ester transfer protein activity in normolipidemic and hyperlipidemic patients with c…
2013
High cholesteryl ester transfer protein (CETP) activity was found to accelerate the progression of atherosclerosis. Apolipoprotein C1 (apoC1) is a potent physiological inhibitor of CETP. ApoC1 operates as CETP inhibitor through its ability to modify the electrostatic charge at the lipoprotein surface. The inhibitory potential of apoC1 has never been studied in high risk patients or in patients with hyperlipidemia. Our aim was to address the functionality of apoC1 as CETP inhibitor in normo- and hyperlipidemic patients with documented coronary artery disease and in patients with type 1 and type 2 diabetes in comparison with normolipidemic-normoglycemic healthy subjects. We confirmed that apo…
Riesgo elevado de disfunción lipoproteica en la diabetes mellitus tipo 2
2008
La diabetes tipo 2 contribuye a un elevado riesgo cardiovascular. Un componente importante de dicho riesgo puede atribuirse a la dislipidemia diabetica, una agrupacion de anomalias de los lipidos y las lipoproteinas plasmaticos que estan interrelacionadas metabolicamente. Sus principales caracteristicas son una elevacion de los trigliceridos, una reduccion de las lipoproteinas de alta densidad (HDL) y un aumento de las lipoproteinas de baja densidad (LDL) pequenas y densas, a lo que se denomina la “triada lipidica aterogenica”. La dislipidemia diabetica se asocia a resistencia a la insulina, obesidad visceral y contenido de grasa hepatica. La resistencia a la insulina esta relacionada con u…

2012
Resumen Fundamento y objetivo La hiperlipidemia familiar combinada (HFC) es un modelo genetico de dislipidemia aterogenica con insulinorresistencia y cardiopatia isquemica precoz. Nuestro objetivo fue evaluar la presencia de alteraciones a nivel carotideo, como marcador de arteriosclerosis sistemica, en sujetos con HFC, y valorar el efecto del tratamiento con 80 mg de atorvastatina diarios durante 2 anos sobre el grosor de la placa de ateroma. Sujetos y metodos Estudiamos 100 sujetos con HFC sin diabetes en prevencion primaria reclutados consecutivamente. Se determinaron parametros clinicos y bioquimicos, y se realizo ecografia carotidea. En los sujetos con placa de ateroma se inicio tratam…
