Noninvasive assessment of liver disease severity in patients with nonalcoholic fatty liver disease (NAFLD) and type 2 diabetes

2023

Background: We evaluated the diagnostic accuracy of simple non-invasive tests(NITs) in NAFLD patients with type 2 diabetes(T2D). Methods: This was an individual patient data meta-analysis of 1780 patients with biopsy-proven NAFLD and T2D. The index tests of interest were FIB-4, NAFLD Fibrosis Score(NFS), APRI, liver stiffness measurement(LSM) by vibration-controlled transient elastography(VCTE) and AGILE 3+. The target conditions were advanced fibrosis, nonalcoholic steatohepatitis(NASH) and fibrotic NASH(NASH plus F2-F4 fibrosis). The diagnostic performance of NITs individually or in sequential combination was assessed by area under receiver operating characteristic curve(AUROC) and by dec…

Antiretroviral therapy and its role in the progression of acute and chronic liver injury

2019

Durante las últimas décadas, la utilización de terapias antirretrovirales combinadas para combatir la infección por el virus de la inmunodeficiencia humana (VIH) ha convertido esta enfermedad en una patología crónica. Por ello, en la actualidad, la morbimortalidad asociada a los pacientes infectados por VIH está fundamentalmente relacionada con el envejecimiento, ciertamente acelerado en comparación con la población general, y con el efecto tóxico crónico tanto de la propia infección vírica como de la terapia antiviral. Así pues, el principal criterio clínico para la elección de unos fármacos antirretrovirales u otros es su seguridad en terapias administradas de por vida. En la presente tes…

High-tech imaging and molecular biomarkers of fibrosis in hypertension-induced left ventricular hypertrophy

2017

La hipertensión arterial (HTA) es el factor de riesgo cardiovascular más importante según la organización mundial de salud. La enfermedad cardiovascular (ECV) es la principal causa de mortalidad en todo el mundo, y representa 17 millones de muertes al año. Se estima que las complicaciones relacionadas con la HTA representan 9,4 millones de eventos cardiovasculares mortales por año. Aproximadamente la mitad de las muertes mundiales debidas a enfermedades cardíacas, accidentes cerebrovasculares e insuficiencia cardíaca se pueden atribuir a la HTA. El sistema cardiovascular es sensible a los estimulantes fisiológicos y patológicos. La elevación de la presión arterial (PA) y el consiguiente est…

Morphology of experimentally denervated and reinnervated rat facial muscle I. Histochemical and histological findings

1994

The morphological changes in rat facial muscles were evaluated after permanent denervation and were compared with findings after immediate reinnervation. Thirty rats underwent transection of the left and right facial nerves immediately followed by hypoglossal-facial nerve anastomosis on the right side (muscular reinnervation) and removal of 8-10 mm of the facial plexus on the left side (permanent muscular denervation). Levator labii muscle samples of both sides were collected sequentially at 2, 6, 7, 10, 20, and 24 weeks after surgery and submitted to routine histological and enzyme histochemical staining procedures. In normal levator labii muscles a typical "chessboard" pattern was found, …

CFTR p.Arg117His associated with CBAVD and other CFTR-related disorders

2013

International audience; BACKGROUND:The high frequency of the cystic fibrosis (CF) transmembrane conductance regulator (CFTR) gene mutation p.Arg117His in patients with congenital bilateral absence of the vas deferens (CBAVD) and in newborns screened for CF has created a dilemma.METHODS:Phenotypic and genotypic data were retrospectively collected in 179 non-newborn French individuals carrying p.Arg117His and a second CFTR mutation referred for symptoms or family history, by all French molecular genetics laboratories, referring physicians, CF care centres and infertility clinics.RESULTS:97% of the patients had the intronic T7 normal variant in cis with p.Arg117His. 89% patients were male, wit…

Association of Dietary Patterns with MRI Markers of Hepatic Inflammation and Fibrosis in the MAST4HEALTH Study

2022

Whereas the etiology of non-alcoholic fatty liver disease (NAFLD) is complex, the role of nutrition as a causing and preventive factor is not fully explored. The aim of this study is to associate dietary patterns with magnetic resonance imaging (MRI) parameters in a European population (Greece, Italy, and Serbia) affected by NAFLD. For the first time, iron-corrected T1 (cT1), proton density fat fraction (PDFF), and the liver inflammation fibrosis score (LIF) were examined in relation to diet. A total of 97 obese patients with NAFLD from the MAST4HEALTH study were included in the analysis. A validated semi-quantitative food frequency questionnaire (FFQ) was used to assess the quality of diet…

Rare ATG7 genetic variants predispose patients to severe fatty liver disease

2022

Background & Aims: Non-alcoholic fatty liver disease (NAFLD) is the leading cause of liver disorders and has a strong heritable component. The aim of this study was to identify new loci that contribute to severe NAFLD by examining rare variants.Methods: We performed whole-exome sequencing in in-dividuals with NAFLD and advanced fibrosis or hepatocellular carcinoma (n = 301) and examined the enrichment of likely pathogenic rare variants vs. the general population. This was followed by validation at the gene level.Results: In patients with severe NAFLD, we observed an enrichment of the p.P426L variant (rs143545741 C>T; odds ratio [OR] 5.26, 95% CI 2.1-12.6; p = 0.003) of autophagy-rela…

Timing effect of intramyocardial hydrogel injection for positively impacting left ventricular remodeling after myocardial infarction

2015

Intramyocardial injection of various injectable hydrogel materials has shown benefit in positively impacting the course of left ventricular (LV) remodeling after myocardial infarction (MI). However, since LV remodeling is a complex, time dependent process, the most efficacious time of hydrogel injection is not clear. In this study, we injected a relatively stiff, thermoresponsive and bioabsorbable hydrogel in rat hearts at 3 different time points - immediately after MI (IM), 3 d post-MI (3D), and 2 w post-MI (2W), corresponding to the beginnings of the necrotic, fibrotic and chronic remodeling phases. The employed left anterior descending coronary artery ligation model showed expected infar…
