A case-control study on risk factors for nuclear, cortical and posterior subcapsular cataract: The Casteldaccia Eye Study

2005

. Purpose: To investigate risk factors for nuclear, cortical and posterior subcapsular age-related cataract. Methods: A case-control study was carried out on subjects aged 40 years and older, living in Casteldaccia, Sicily. Twenty-seven potential risk factors were investigated. Nuclear, cortical and posterior subcapsular opacities of the lens were classified according to the Lens Opacities Classification System II. Subjects with advanced lens opacities represented the cases, while an identical number of subjects without or with early cataract, matched for sex and age, were recruited as controls from within the same population. Results: Univariate analysis showed that myopia and iris atrophy…

Étude des tendances dysfonctionnelles de la personnalité chez des auteurs d’infractions sexuelles

2014

Objective A review of the literature reveals a consensus on the high prevalence of personality disorders among sexual offenders. Studies show that there is no unique personality profile for sex offenders. In France, little research has been conducted on this population with standardized assessment tools. The objective of the present study is to identify the distribution of personality disorders among sexual offenders using a new French questionnaire, i.e. the TD12. In view of the literature, we postulate that this tool will identify the diversity of personality disorders observed by various authors, but with a higher proportion of cluster B disorders. Methodology This study was conducted am…

2013

Objectives The purpose of this study was to compare sulfur hexafluoride microbubble (SonoVue)-enhanced myocardial contrast echocardiography (MCE) with single-photon emission computed tomography (SPECT) relative to coronary angiography (CA) for assessment of coronary artery disease (CAD). Background Small-scale studies have shown that myocardial perfusion assessed by SonoVue-enhanced MCE is a viable alternative to SPECT for CAD assessment. However, large multicenter studies are lacking. Methods Patients referred for myocardial ischemia testing at 34 centers underwent rest/vasodilator SonoVue-enhanced flash-replenishment MCE, standard Tc-99m-labeled electrocardiography-gated SPECT, and quanti…

THU0248 GLOMERULAR AND TUBULOINTERSTITIAL LESIONS IN PER-PROTOCOL REPEAT BUT NOT BASELINE KIDNEY BIOPSY PORTEND RELAPSE AND LONG-TERM RENAL FUNCTION …

2020

Background:In patients with lupus nephritis (LN), clinical response to treatment and renal histopathology have been shown to be discordant. No clinical or laboratory markers have to date been shown to reliably portend renal prognosis, in particular renal function impairment.Objectives:To investigate whether per-protocol repeat renal biopsies are predictive of LN relapses and long-term impairment of renal function.Methods:Forty-two patients with an incident biopsy-proven active proliferative (class III/IV ± V) LN from the LN database of the Université catholique de Louvain were included in the present retrospective study. Per-protocol repeat kidney biopsies were performed in all patients aft…

Accuracy of the water-siphon test associated to barium study in a high prevalence gastro-oesophageal reflux disease population: a novel statistical a…

2010

Summary Rationale, aims and objectives  Gastro-oesophageal reflux disease (GORD) is ‘a condition which develops when the reflux of gastric content causes troublesome symptoms or complications’. Instrumental diagnostic tests generally used for GORD are 24-hour pH-metry and upper gastrointestinal (GI) endoscopy but barium study associated with provocative manoeuvres such as the water-siphon test (WST), has also been used for GORD. The aim of this paper was to estimate the accuracy of several tests in patients with GORD in a tertiary care setting, focusing on WST, which is rapid and non-invasive, simple to perform and well-tolerated by patients. Method  A total of 172 consecutive patients, sym…

AB0266 METHOTREXATE AND CARDIOVASCULAR RISK IN RHEUMATIC DISEASES:A COMPREHENSIVE REVIEW

2021

Background:The management of inflammatory rheumatic disease has evolved in the last decade with the importance of the management of comorbidities. Methotrexate is the cornerstone of inflammatory rheumatic disease management, but its cardiovascular effects are still poorly understoodObjectives:To assess the cardiovascular impact of methotrexate in inflammatory rheumatic disease.Methods:A systematic review of the literature, following the prisma recommandations, was performed on the PubMed and Embase databases with the following keywords: (“Methotrexate”) AND (“cardiovascular”). We included papers written in English and including patients older than 18 years.Results:570 references were identi…

Magnetic resonance in isolated noncompaction of the ventricular myocardium

2010

Abstract Non-compaction of the ventricular myocardium (LCVM) is a rare disorder of myocardial morphogenesis usually diagnosed in paediatric age. The diagnosis was echocardiographically made on the basis of a reported spongeous/compacted ratio >2 in one or more segments of the left ventricle during the diastolic period. We aimed to test the diagnostic accuracy of cardiovascular magnetic resonance (CMR) imaging in distinguishing pathological left ventricular non-compaction. Methods We collected a consecutive series of 8 patients, 5 males and 3 females, with a mean age of 14.9 years with non-compaction of left ventricular myocardium. All patients were admitted in our divisions of cardiology. I…

PWE-139 Further Validation of Terminal Peptide of Procollagen Iii (PIIINP) for the Detection and Assessment of Nonalcoholic Steatohepatitis in Patien…

2013

Introduction PIIINP has recently been shown to discriminate between simple steatosis (SS) and NASH both in patients without advanced fibrosis and in patients with all degrees of fibrosis 1 . In this study we validated PIIINP as a biomarker of NASH in a cohort of patients with biopsy proven NAFLD and evaluated its performance at the proposed diagnostic thresholds. Methods 71 patients with NAFLD and no evidence of other liver disease were included in this study. Liver biopsies were performed on all patients and analysed by a expert liver histopathologist. All liver biopsies were of suitable size for analysis (> 12mm and > 5 portal tracts) and classified in a dichotomous manner into those with…

Non-invasive Diagnostic Approach to NASH: Biological Markers

2020

Non-alcoholic fatty liver disease (NAFLD) prevalence and incidence are dramatically increasing in parallel with the epidemics of both obesity and type 2 diabetes, accounting for the most growing cause of chronic liver disease, of hepatocellular carcinoma and of end-stage liver disease leading to liver transplantation. Natural history studies clearly demonstrated that among NAFLD population, those with non-alcoholic steatohepatitis (NASH) have a double risk of fibrosis progression, and that the severity of liver fibrosis is the main driver of hepatic and extrahepatic prognosis. Consistently, the availability of non-invasive markers to be used in NAFLD patients represents a relevant medical n…

Changes in the Expression of Tachykinin Receptors in the Rat Uterus During the Course of Pregnancy1

2001

In the mammalian female reproductive tract, tachykinin neuropeptides, such as substance P (SP), are localized to a population of sensory fibers and their precise physiological role is still unknown. The aim of the present study was to characterize the population of tachykinin receptors in the pregnant rat uterus and to assess their regulation during the course of pregnancy and after delivery. The expression of the tachykinin NK(1) receptor (NK(1)R), the tachykinin NK(2) receptor (NK(2)R), and the tachykinin NK(3) receptor (NK(3)R) in uteri from rats at different stages of pregnancy and on Day 1 postpartum was investigated by using a semiquantitative reverse transcription-polymerase chain re…
