Arteriosclerosis carotídea subclínica en pacientes con hiperlipidemia familiar combinada. Evolución tras dos años de tratamiento con dosis altas de a…
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…
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…
ScreenPro FH - Screening Project for Familial Hypercholesterolemia in Central, Southern and Eastern Europe: Basic Epidemiology
2017
Uvod: I přes velký pokrok v nedavne době je familiarni hypercholesterolemie (FH) stale jestě celosvětově podceňovane, nedostatecně diagnostikovane, a tedy i nedostatecně lecene onemocněni. O přesne prevalenci pacientů postižených familiarni hypercholesterolemii v regionu středni, východni a jižni Evropy (CESE) mame jen velmi malo informaci. Cilem studie bylo popsat na zakladě dostupných udajů epidemiologickou situaci v regionu CESE. Metody: Vsichni vedouci představitele projektu ScreenPro FH v jednotlivých oblastech byli požadani o poskytnuti lokalnich udajů, ktere se týkaji (a) expertniho odhadu prevalence FH, (b) již fungujicich zdravotnických zařizeni, (c) použitých diagnostických kriter…
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…
ScreenPro FH - Screening project for familial hypercholesterolemia in central, southern and eastern Europe: Rationale and design
2017
Familial hypercholesterolemia (FH) is a genetic disorder with well-known genetic transmission and clinical course. Despite great recent progress, FH is still underestimated, under-diagnosed and thus undertreated. Furthermore it represents a significant healthcare challenge as a common risk factor for the premature development of coronary heart disease. The ScreenPro FH Project is an international network project aiming at improving complex care - from timely screening, through diagnosis to up-to-date treatment of familial hypercholesterolemia in Central, Eastern and Southern Europe. An important task for the project is to harmonise and unify diagnostic and therapeutic approaches in particip…
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…
Do Sign Language Videos Improve Web Navigation for Deaf Signer Users?
2010
The efficacy of video-based sign language (SL) navigation aids to improve Web search for Deaf Signers was tested by two experiments. Experiment 1 compared 2 navigation aids based on text hyperlinks linked to embedded SL videos, which differed in the spatial contiguity between the text hyperlink and SL video (contiguous vs. distant). Deaf Signers’ performance was similar in Web search using both aids, but a positive correlation between their word categorization abilities and search efficiency appeared in the distant condition. In Experiment 2, the contiguous condition was compared with a text-only hyperlink condition. Deaf Signers became less disorientated (used shorter paths to find the tar…
Perlecan Maintains the Integrity of Cartilage and Some Basement Membranes
1999
Perlecan is a heparan sulfate proteoglycan that is expressed in all basement membranes (BMs), in cartilage, and several other mesenchymal tissues during development. Perlecan binds growth factors and interacts with various extracellular matrix proteins and cell adhesion molecules. Homozygous mice with a null mutation in the perlecan gene exhibit normal formation of BMs. However, BMs deteriorate in regions with increased mechanical stress such as the contracting myocardium and the expanding brain vesicles showing that perlecan is crucial for maintaining BM integrity. As a consequence, small clefts are formed in the cardiac muscle leading to blood leakage into the pericardial cavity and an ar…
Stroboscopic detection of nuclear resonance in an arbitrary scattering channel
2015
The theory of heterodyne/stroboscopic detection of nuclear resonance scattering is developed, starting from the total scattering matrix as a product of the matrix of the reference sample and the sample under study. This general approach holds for any dynamical scattering channel. The forward channel, which is discussed in detail in the literature, reveals the speciality that electronic scattering causes only an energy independent diminution of the intensity. For all other channels, complex resonance line shapes in the heterodyne/stroboscopic spectra - as a result of interference of electronic and nuclear scattering - is encountered. The grazing incidence case is evaluated and described in d…
Prevalence, risk factor burden, and severity of coronary artery disease in patients with heterozygous familial hypercholesterolemia hospitalized for …
2019
Individuals with heterozygous familial hypercholesterolemia (FH) are at high risk of early myocardial infarction (MI). However, coronary artery disease (CAD) burden of FH remains not well described, especially for French patients.The objective of this study was to assess the prevalence of FH and severity of CAD from a large database of a French regional registry of acute MI.All consecutive patients hospitalized for an acute MI in a multicenter database from 2001 to 2017 were considered. FH was diagnosed using an algorithm adapted from the Dutch Lipid Clinic Network criteria. The prevalence and clinical features of FH and the severity of CAD were assessed.Among the 11,624 patients included i…
