Incidence, Diagnosis, and Outcome of Acquired Thrombotic Thrombocytopenic Purpura (aTTP): A Nationwide Survey By the Spanish Apheresis Group
2019
Introduction: Acquired thrombotic thrombocytopenic purpura (aTTP) is a rare disease characterized by a severe deficiency of the enzymatic activity of ADAMTS13 caused by autoantibodies, with an incidence of 3-4 x106inhabitants per year according to the few published data available. Accurate estimates of the incidence of aTTP are important to assess the resources required for current treatments and to anticipate the need to develop new treatments. The aim of this study was to determine the actualincidence of aTTP in Spain, as well as its diagnosis, management, and associated complications. Material and methods:A cross-sectional surveywascarried out among hematologists working in Spanish hospi…
Effect of dietary interventions during weaning period on parental practice and lipoproteins and vitamin D status in two-year-old children
2016
ABSTRACT Objective: Evaluate if a two-day course for parents on nutrition and applied baby food preparation had an effect on child’s intake of home-made foods, lipid concentration, and vitamin D status. Design: Randomized controlled trial at age 6 months and follow-up at ages 15 and 24 months. Setting: Four health care clinics in Kristiansand, Norway. Subjects: Thirty-nine pairs of 6-month-old children and their parents in the intervention group and 20 pairs in the control group. Results: At age 15 months, the intervention group had lower intakes of ready-made porridge (2.0 vs. 5.8 servings per week (p < 0.05)), lower intake of canned baby food (2.9 vs. 6.3 servings per week (p < 0.05)) and…
Statistical characterization of deviations from planned flight trajectories in air traffic management
2016
Understanding the relation between planned and realized flight trajectories and the determinants of flight deviations is of great importance in air traffic management. In this paper we perform an in depth investigation of the statistical properties of planned and realized air traffic on the German airspace during a 28 day periods, corresponding to an AIRAC cycle. We find that realized trajectories are on average shorter than planned ones and this effect is stronger during night-time than daytime. Flights are more frequently deviated close to the departure airport and at a relatively large angle to destination. Moreover, the probability of a deviation is higher in low traffic phases. All the…
Does Pasteurized Donor Human Milk Efficiently Protect Preterm Infants Against Oxidative Stress?
2019
International audience; Pasteurized donor human milk (DHM) is the preferred alternative for infant nutrition when own mother's milk (OMM) is unavailable. Whether DHM is an efficient means for protecting preterm infants from oxidative stress remains unknown. We quantified a panel of oxidative stress biomarkers in urine samples from preterm infants (≤32 weeks of gestation and a birth weight ≤1500 g) receiving ≥80% of feeding volume as either DHM or OMM. The noninvasive in vivo assessment of oxidative stress showed no statistically significant difference between both groups at the time when full enteral nutrition (150 mL/kg body weight) was achieved and until hospital discharge. In addition, t…
De la querelle du quinquina à la querelle de l’hydroxychloroquine, ou comment notre système de protection du médicament est mis à l’épreuve : une ana…
2020
Resume La querelle actuelle sur l’utilisation de l’hydroxychloroquine, dans le cadre de la coronavirus disease 2019 (covid-19), trouve un echo dans une autre querelle, celle du quinquina, qui prit place au XVIIe siecle. Cet aparte historique est de nature a nous rappeler que les disputes scientifiques ont toujours existe, et il n’est donc pas etonnant que les proprietes de l’hydroxychloroquine soient sujettes a polemique. Cependant, les faits sont les faits : son efficacite est douteuse, alors que les risques sont certains. C’est pourquoi en France le Premier ministre a fait le choix d’encadrer sa prescription par un decret. Mais ce decret, bien que surement la seule option possible, soulev…
E2F1 interacts with BCL-xL and regulates its subcellular localization dynamics to trigger cell death
2018
International audience; E2F1 is the main pro-apoptotic effector of the pRB-regulated tumor suppressor pathway by promoting the transcription of various pro-apoptotic proteins. We report here that E2F1 partly localizes to mitochondria, where it favors mitochondrial outer membrane permeabilization. E2F1 interacts with BCL-xL independently from its BH3 binding interface and induces a stabilization of BCL-xL at mitochondrial membranes. This prevents efficient control of BCL-xL over its binding partners, in particular over BAK resulting in the induction of cell death. We thus identify a new, non-BH3-binding regulator of BCL-xL localization dynamics that influences its anti-apoptotic activity.
Outcome of liver transplantation for hepatopulmonary syndrome: a Eurotransplant experience.
2019
Hepatopulmonary syndrome (HPS) is a pulmonary vascular complication of liver disease that affects up to 30% of patients with cirrhosis [1]. Intrapulmonary vascular dilatations and shunts result in gas exchange abnormalities, ranging from elevated alveolar-arterial oxygen gradients with no hypoxemia to very severe hypoxemia [1, 2]. Currently, liver transplantation (LT) is the only treatment option [3]. The Model for End-Stage Liver Disease (MELD) is a scoring system for assessing liver disease severity that has been validated to predict the 3-months waitlist mortality, and is used by Eurotransplant for prioritising allocation of liver transplants [4]. Footnotes This manuscript has recently b…
International consensus: What else can we do to improve diagnosis and therapeutic strategies in patients affected by autoimmune rheumatic diseases (r…
2017
Autoimmune diseases are a complex set of diseases characterized by immune system activation and, although many progresses have been done in the last 15 years, several unmet needs in the management of these patients may be still identified. Recently, a panel of international Experts, divided in different working groups according to their clinical and scientific expertise, were asked to identify, debate and formulate a list of key unmet needs within the field of rheumatology, serving as a roadmap for research as well as support for clinicians. After a systematic review of the literature, the results and the discussions from each working group were summarised in different statements. Due to th…
Identification of a large, fast-expanding HIV-1 subtype B transmission cluster among MSM in Valencia, Spain
2017
We describe and characterize an exceptionally large HIV-1 subtype B transmission cluster occurring in the Comunidad Valenciana (CV, Spain). A total of 1806 HIV-1 protease-reverse transcriptase (PR/RT) sequences from different patients were obtained in the CV between 2004 and 2014. After subtyping and generating a phylogenetic tree with additional HIV-1 subtype B sequences, a very large transmission cluster which included almost exclusively sequences from the CV was detected (n = 143 patients). This cluster was then validated and characterized with further maximum-likelihood phylogenetic analyses and Bayesian coalescent reconstructions. With these analyses, the CV cluster was delimited to 11…
Cosavirus, Salivirus and Bufavirus in Diarrheal Tunisian Infants
2016
International audience; Three newly discovered viruses have been recently described in diarrheal patients: Cosa-virus (CosV) and Salivirus (SalV), two picornaviruses, and Bufavirus (BuV), a parvovirus. The detection rate and the role of these viruses remain to be established in acute gastroen-teritis (AGE) in diarrheal Tunisian infants. From October 2010 through March 2012, stool samples were collected from 203 children <5 years-old suffering from AGE and attending the Children's Hospital in Monastir, Tunisia. All samples were screened for CosV, SalV and BuV as well as for norovirus (NoV) and group A rotavirus (RVA) by molecular biology. Positive samples for the three screened viruses were …
