Efecto del género y de la obesidad en la lipemia posprandial en sujetos sanos normolipidémicos no diabéticos y sujetos con hiperlipemia familiar comb…
2006
Introduccion Un nuevo metodo basado en la autodeterminacion de trigliceridos (TG) capilares permite un mejor conocimiento de la lipemia posprandial (LP). Los objetivos de nuestro estudio son analizar el efecto del genero y la obesidad sobre la LP valorada por medicion capilar de TG diurnos mediante Accutrend GCT® en sujetos sanos y sujetos con hiperlipemia familiar combinada (HFC). Material y metodos Hemos estudiado a 23 sujetos con HFC no relacionados entre si (10 hombres) y a 45 sujetos (29 hombres) normolipidemicos no diabeticos. Todos ellos realizaron tres perfiles diarios de TG capilares durante una semana. Resultados En los sujetos sanos normolipidemicos no diabeticos encontramos valo…
Asociación de pravastatina y fenofibrato (Pravafenix®). Estudios de seguridad
2014
Resumen Aunque el colesterol unido a lipoproteinas de baja densidad (cLDL) es el objetivo primario de tratamiento para reducir el riesgo cardiovascular, el incremento de trigliceridos y el descenso del colesterol unido a lipoproteinas de alta densidad (cHDL) constituyen el denominado riesgo cardiovascular residual. El tratamiento con estatinas asociado a fibratos es una posibilidad real de tratamiento del riesgo cardiovascular total. Sin embargo, esta asociacion puede con frecuencia asociarse a efectos adversos, especialmente musculares y hepaticos. Por sus caracteristicas farmacologicas, la asociacion de pravastatina con fenofibrato puede ser eficaz y segura, con escasos efectos secundario…
Lipid profile during pregnancy in HIV-infected women
2006
Purpose: We investigated the evolution of serum lipid levels in HIV-infected pregnant women and the potential effect of antiretroviral treatment during pregnancy using data from a national surveillance study. Method: Fasting lipid measurements collected during routine care in pregnancy were used, analyzing longitudinal changes and differences in lipid values at each trimester by protease inhibitors (Pls) and stavudine use. Multivariate analyses were used to control for simultaneous factors potentially leading to hyperlipidemia. Study population included 248 women. Results: Lipid values increased progressively and significantly during pregnancy: mean increases between the first and third tri…
Työttömät : Helsingin Sanomien mielipidekirjoituksissa rakentuvia kulttuurisia merkityksiä
2015
Tutkimus tarkastelee Helsingin Sanomissa vuosien 2008 ja 2013 välillä julkaistuja työttömien mielipidekirjoituksia. Tutkimustehtävänä on ymmärtää millaisia sosiokulttuurisia merkityksiä ja arvoja työlle ja työttömyydelle annetaan. Keskeisinä tutkimuskäsitteinä toimivat työ ja työttömyys, jotka määritellään laajasti aiempaa tutkimuskirjallisuutta hyödyntäen. Tutkimuksen metodologia pohjaa diskurssianalyysiin. Diskurssianalyysin avulla luokittelen tutkimusaineiston diskursseiksi, joita tarkastelen tutkimuksen analyysivaiheessa. Työttömien mielipidekirjoitukset työttömyydestä luovat yhdenmukaisen kertomuksen. Tutkimuksen pohjalta työttömyys näyttäytyy kulttuurisen normaalin ulkopuolella olemis…
Dyslipidemia management with medical nutrition therapy: current status and perspectives
2013
In Italy, patients with dyslipidennia account for 15-20% of the adult population with major healthcare and socio-economic impact. According to the ESC/EAS guidelines for the management of dyslipidemias, desirable cholesterol and triglyceride levels can be achieved with a synergy between drug treatment and adequate diet therapy. However, what diets should be adopted? In this review article, different types of dietary treatments are compared, with a special focus on diet education. The new scientific frontier of nutrigenetics is also discussed.
Intestinal CD36 : A long chain fatty acid receptor which controls post prandial hypertriglyceridemia, endotoxemia and intestinal epithelium integrity
2014
Post prandial hypertriglyceridemia represents a risk factor for cardio-vascular diseases and it is associated with metabolic syndrom, obesity, and insulino-resistance. The intestine influences lipid bioavailibility and post prandial hypertriglyceridemia. It controls the quantity and the quality of secreted chylomicrons by adapting its metabolism according to the lipid content of the diet. Nevertheless, the mechanism of dietary lipid detection by the enterocyte is not understood. Our work demonstrates that the transmembrane glycoprotein CD36 is a Long Chain Fatty Acid (LCFA) receptor which triggers ERK1/2 activation. This activation is responsible for the induction of mRNA rate of 3 key prot…
Anti-inflammatory Therapies for Cardiovascular Disease: Signaling Pathways and Mechanisms
2019
Cardiovascular diseases (CVD) are the clinical manifestation of atherosclerosis, a chronic inflammatory disease promoted by several risk factors such as dyslipidemia, type 2 diabetes mellitus, hypertension, and smoking. Acute CVD events are the result of an unresolved inflammatory chronic state that promotes the rupture of unstable plaque lesions. Of note, the existing intensive therapies modify risk factors but do not prevent life-threatening recurrent ischemic events in high-risk patients, who have a residual inflammatory risk displayed by increased C-reactive protein (CRP) levels. Better understanding of the role of innate and adaptive immunity in plaque development and rupture has led t…
Physico-chimie des lipopolysaccharides et réponse inflammatoire : rôle des lipoprotéines
2014
LPS is a potent bacterial pro-inflammatory agent, consisting of hydrophilic, polysaccharide part and of a lipid A which is considered like active moiety. Nevertheless, the O chain of LPS influences their aggregation in aqueous media. Therefore, our goal has been to determine the role of O chain on the LPS biological and physiopathological effects. Our work was organized according to three main axes, and led to the following findings :- development of a new LPS assay by LC-MS/MS. The combination of this new technique with LAL test allowed us to calculate an inactivation ratio which reflects the ability of host organism to inactivate LPS, especially through their transfer to HDL by PLTP. The …
Distribution of Intraocular Pressure and Its Association with Ocular Features and Cardiovascular Risk Factors
2013
Purpose To describe the distribution of intraocular pressure (IOP) and its association with ocular features and cardiovascular risk factors in an adult European cohort. Design Population-based, cross-sectional study. Participants This analysis was based on a Gutenberg Health Study (GHS) cohort that included 4335 eligible enrollees from among 5000 subjects who participated in the survey from 2007 through 2008. The age range was 35 to 74 years at enrollment. Methods Participants underwent a standardized protocol with a comprehensive questionnaire; ophthalmic examination including slit-lamp biomicroscopy, noncontact tonometry, fundus photography, central corneal thickness measurement, and visu…
RELAZIONI TRA PARAMETRI LIPIDICI E MASSA VENTRICOLARE SINISTRA IN SOGGETTI CON IPERTENSIONE ARTERIOSA ESSENZIALE
2014
Dati non univoci sono riportati in letteratura sul ruolo della dislipidemia nello sviluppo dell’ipertrofia ventricolare sinistra. Scopo del nostro studio, è stato quello di valutare le potenziali associazioni dei principali parametri lipidici con la massa ventricolare sinistra (LVM) in pazienti con ipertensione essenziale (EHs). Abbiamo arruolato 724 soggetti con EH (età media 45±12 anni; 63% maschi), senza complicanze cardiovascolari e non trattati con farmaci ipolipemizzanti. In tutti i soggetti dono stati dosati la colesterolemia totale (Tchol), la trigliceridemia (TG) e il colesterolo HDL (HDLc). Il colesterolo LDL (LDLc) è stato stimato con la formula di Friedewald ed è stato calcolato…
