Characteristics of liver cirrhosis in Italy: Evidence for a decreasing role of HCV aetiology
2017
Previous cross-sectional studies have shown that hepatitis C virus (HCV) infection had been the main agent associated with liver cirrhosis in Italy. Abstract BACKGROUND: Previous cross-sectional studies have shown that hepatitis C virus (HCV) infection had been the main agent associated with liver cirrhosis in Italy. AIM: To assess epidemiological, laboratory and clinical features of liver cirrhosis in Italy in 2014. PATIENTS: Out of the 2557 consecutive subjects evaluated in 16 hospitals located throughout Italy in 2014, 832 (32.6%) had liver cirrhosis and were enrolled in this study. RESULTS: The mean age of subjects was 60.3years, with a male/female ratio of 1.7; 74.9% of cases had Child…
Perceived effectiveness, restrictiveness and compliance with containment measures against the Covid-19 pandemic: an international comparative study i…
2021
National governments took action to delay the transmission of the coronavirus (SARS-CoV-2) by implementing different containment measures. We developed an online survey that included 44 different containment measures. We aimed to assess how effective citizens perceive these measures, which measures are perceived as violation of citizens’ personal freedoms, which opinions and demographic factors have an effect on compliance with the measures, and what governments can do to most effectively improve citizens’ compliance. The survey was disseminated in 11 countries: UK, Belgium, Netherlands, Bulgaria, Czech Republic, Finland, India, Latvia, Poland, Romania, and Sweden. We acquired 9543 unique r…
Evolution of chromatin-remodeling complexes: comparative genomics reveals the ancient origin of "novel" compensasome genes.
2003
Dosage compensation in Drosophila is mediated by a complex, called compensasome, com- posed of at least five proteins and two noncoding RNAs. Genes encoding compensasome proteins have been collectively named male-specific lethals or msls. Recent work showed that three of the Drosophila msls (msl-3, mof, and mle) have an ancient origin. In this study, I describe likely orthologues of the two re- maining msls, msl-1 and msl-2, in several inverte- brates and vertebrates. The MSL-2 protein is the only one found in Drosophila and vertebrate genomes that contains both a RING finger and a peculiar type of CXC domain, related to the one present in Enhancer of Zeste proteins. MSL-1 also contains two…
Delisting HCV-infected liver transplant candidates who improved after viral eradication: Outcome 2 years after delisting
2018
International audience; BACKGROUNDS & AIMS: Treating patients with decompensated cirrhosis with direct-acting antiviral (DAA) therapy while on the waiting list for liver transplantation results in substantial improvement of liver function allowing 1 in 4 patients to be removed from the waiting list or delisted, as reported in a previous study promoted by the European Liver and Intestine Transplant Association (ELITA). The aim of this study was to report on clinical outcomes of delisted patients, including mortality risk, hepatocellular carcinoma development and clinical decompensation requiring relisting. METHODS: One hundred and forty-two HCV-positive patients on the liver transplant waiti…
The Choice of the Filtering Method in Microarrays Affects the Inference Regarding Dosage Compensation of the Active X-Chromosome
2011
BackgroundThe hypothesis of dosage compensation of genes of the X chromosome, supported by previous microarray studies, was recently challenged by RNA-sequencing data. It was suggested that microarray studies were biased toward an over-estimation of X-linked expression levels as a consequence of the filtering of genes below the detection threshold of microarrays.Methodology/principal findingsTo investigate this hypothesis, we used microarray expression data from circulating monocytes in 1,467 individuals. In total, 25,349 and 1,156 probes were unambiguously assigned to autosomes and the X chromosome, respectively. Globally, there was a clear shift of X-linked expressions toward lower levels…
Evolution of sex chromosomes: dosage compensation of the Lcp1-4 gene cluster on the evolving neo-X chromosome in Drosophila miranda.
2007
In Drosophila miranda the small multigene family of the larval cuticle protein (Lcp1-4) genes resides on the evolving neo-X and neo-Y sex chromosome pair while in the sibling species Drosophila pseudoobscura and Drosophila persimilis the gene cluster is inherited autosomally. The neo-Y chromosomal Lcp1, Lcp2 and Lcp4 genes are, as previously shown by us, not expressed and only Lcp3 is expressed at a strongly reduced level. As a first step in understanding the evolutionary mechanism(s) transforming an autosome into a dosage compensated X we analysed the expression behaviour and promoter structure of the Lcp1-4 genes on the neo-X. The normalized relative expression levels reveal that all four…
Survival of patients with spinal muscular atrophy type 1.
2013
BACKGROUND: Spinal muscular atrophy type 1 (SMA1) is a progressive disease and is usually fatal in the first year of life. METHODS: A retrospective chart review was performed of SMA1 patients and their outcomes according to the following choices: letting nature take its course (NT); tracheostomy and invasive mechanical ventilation (TV); continuous noninvasive respiratory muscle aid (NRA), including noninvasive ventilation; and mechanically assisted cough. RESULTS: Of 194 consecutively referred patients enrolled in this study (103 males, 91 females), NT, TV, and NRA were chosen for 121 (62.3%), 42 (21.7%), and 31 (16%) patients, respectively. Survival at ages 24 and 48 months was higher in …
Determining Factors and Critical Periods in the Formation of Eating Habits: Results from the Habeat Project
2016
Un article correspondant à cette présentation devrait paraître en 2017 dans Annals of Nutrition and Metabolism.Un article correspondant à cette présentation devrait paraître en 2017 dans Annals of Nutrition and Metabolism.; Eating habits form early during childhood and are likely to track until the beginning of adulthood. Thus, understanding the formation of eating habits is important. In the HabEat* project we focused on the development of preferences for vegetables since they are the less liked foods for children. Based on the analyses of data from different European cohorts, HabEat found that breast milk may facilitate the consumption of vegetables in later childhood. HabEat found some e…
Successful Management of Fulminant Pulmonary Embolism Using a Novel Portable Extracorporeal Life Support System
2010
A 46-year-old man presented to the emergency room with pain in his left leg, dyspnea, and general cyanosis. During examination he collapsed and required resuscitation. Under suspicion of pulmonary embolism, a new portable "click 'n run" extracorporeal life support system (LIFEBRIDGE-B(2)T [Medizintechnik AG, Ampfing, Germany]) was implanted by the femoral vessels under resuscitation within 15 minutes of presentation. The patient was stabilized, despite severe decompensation (pH, 6.8), and could be transferred for a computed tomographic scan, which confirmed massive pulmonary embolism. Still connected to the life support system, the patient was transferred to the operating room. After a pulm…
Enhancement of brain event-related potentials to speech sounds is associated with compensated reading skills in dyslexic children with familial risk …
2014
Specific reading disability, dyslexia, is a prevalent and heritable disorder impairing reading acquisition characterized by a phonological deficit. However, the underlying mechanism of how the impaired phonological processing mediates resulting dyslexia or reading disabilities remains still unclear. Using ERPs we studied speech sound processing of 30 dyslexic children with familial risk for dyslexia, 51 typically reading children with familial risk for dyslexia, and 58 typically reading control children. We found enhanced brain responses to shortening of a phonemic length in pseudo-words (/at:a/ vs. /ata/) in dyslexic children with familial risk as compared to other groups. The enhanced bra…
