Sleep is markedly altered in intensive care unit (ICU) patients and may alter respiratory performance. Our objective was to assess the impact of sleep alterations on weaning duration. We conducted a prospective physiological study performed in a French teaching hospital. ICU-patients intubated at least 24 h and difficult-to-wean were included. Complete polysomnography was performed after the first spontaneous breathing trial failure. Presence of atypical sleep, duration of sleep stages particularly rapid eye movement (REM) sleep, and electroencephalogram (EEG) reactivity at eye opening were assessed by a neurologist...

OBJECTIVE: Assess the influence of background music tempo on driving performance. BACKGROUND: Music with a fast tempo is known to increase the level of arousal, whereas the reverse is observed for slow music. The relationship between driving performance and level of arousal was expected to take the form of an inverted U-curve. METHOD: Three experiments were undertaken to manipulate the musical background during driving. In Experiment 1, the driver's preferred music track played at its original and modified (plus or minus 30%) tempo were used together with the simple ticking of a metronome...

The Big Gravitational Spectrometer (BGS) takes advantage of the strong influence of the Earth's gravity on the motion of ultracold neutrons (UCNs) that makes it possible to shape and measure UCN spectra. We optimized the BGS to investigate the "small heating" of UCNs, that is, the inelastic reflection of UCNs from a surface accompanied by an energy change comparable with the initial UCN energy. UCNs whose energy increases are referred to as "Vaporized UCNs" (VUCNs). The BGS provides the narrowest UCN spectra of a few cm and the broadest "visible" VUCN energy range of up to ∼150 cm (UCN energy is given in units of its maximum height in the Earth's gravitational field, where 1...

Multiple aspects of mitochondrial function and dynamics remain poorly studied in the skeletal muscle of pediatric models in response to a short-term high-fat diet (HFD). This study investigated the impact of a short-term HFD on mitochondrial function and dynamics in the oxidative soleus (SOL) and glycolytic extensor digitorum longus (EDL) muscles in young rats. Young male Wistar rats were submitted to either HFD or normal chow (NCD) diets for 14 days. Permeabilized myofibers from SOL and EDL were prepared to assess mitochondrial respiration and reactive oxygen species (ROS) production...

BACKGROUND: Club Cell Secretory Protein (CCSP) G38A polymorphism has recently been involved in lung epithelial susceptibility to external injuries. Lung transplantation (LT) is currently limited by ischemia-reperfusion injury leading to Primary Graft Dysfunction (PGD). We thus hypothesized that donor CCSP G38A polymorphism might impact the risk of PGD following LT. METHODS: We focused on LT included in the French multicentric Cohort in Lung Transplantation (COLT), performed between January 2009 and December 2014, and associated with preoperative blood samples from the donor and the recipient...

The isolation of Legionella from respiratory samples is the gold standard for Legionnaires' disease (LD) diagnosis and enables epidemiological studies and outbreak investigations. The purpose of this work was to adapt and evaluate the performance of an amoebic coculture procedure (the amoebae plate test, APT) to the recovery of Legionella strains from respiratory samples, in comparison with axenic culture and a liquid-based amoebic coculture (LAC). Axenic culture, LAC, and APT were prospectively performed on 133 respiratory samples from patients with LD...

Pulmonary and systemic antifungal immunity influences quality of life and survival of people with cystic fibrosis. Aspergillus fumigatus (Af) induces specific IgG and IgE. Mast cells respond to IgE, IgG and direct interactions with Af. Mast cells are the source of the protease tryptase. We aimed at evaluating serum baseline tryptase as a potential biomarker of the Af-host interaction in cystic fibrosis patients. Serum baseline tryptase, IgE and IgG directed to Af extract and Af molecular allergens were measured in 76 cystic fibrosis patients...

In this issue of JEM, Álvarez-Prado et al. ( designed a DNA capture library allowing them to identify 275 genes targeted by AID in mouse germinal center B cells. Using the molecular features of these genes to feed a machine-learning algorithm, they determined that high-density RNA PolII and Spt5 binding-found in 2.3% of the genes-are the best predictors of AID specificity.

Late-onset noninfectious pulmonary complications (LONIPCs) affect 6% of allogeneic stem cell transplantation (SCT) recipients within 5 years, conferring subsequent 5-year survival of 50%. Lung transplantation is rarely performed in this setting due to concomitant extrapulmonary morbidity, excessive immunosuppression and concerns about recurring malignancy being considered contraindications. This study assesses survival in highly selected patients undergoing lung transplantation for LONIPCs after SCT.SCT patients undergoing lung transplantation at 20 European centres between 1996 and 2014 were included...

Sarcoma represents a highly heterogeneous group of tumours. We report here the first unbiased and systematic search for gene fusions combined with unsupervised expression analysis of a series of 184 small round cell sarcomas. Fusion genes were detected in 59% percent of samples, with half of them being observed recurrently. We identified biologically homogeneous groups of tumours such as the CIC-fused (to DUX4, FOXO4 or NUTM1) and BCOR-rearranged (BCOR-CCNB3, BCOR-MAML3, ZC3H7B-BCOR and BCOR internal duplication) tumour groups...

A Q fever epidemic occurred in 2013 in a small military residential area in Cayenne, French Guiana. A retrospective cohort study was conducted to identify Q fever risk factors. Confirmed acute Q fever case was defined as positive serology (IgM ≥ 50 and phase II IgG ≥ 200) and/or positive qPCR on serum or blood. In addition, wild mammals were captured at the study site and tested by serology and real-time PCR performed on blood, vaginal swabs and ticks. The attack rate was 20 percent (11/54). All the cases were symptomatic with fever >38...

Tall stature is not a common motive for medical consultation, even though by definition 2.5 % of children in the general population are concerned. It is usually defined as height greater than+2 standard deviations (SD) using the appropriate growth chart for age and gender, or a difference greater than +2 SD between actual height and target height. With a patient presenting tall stature, the physician has to determine whether it is a benign feature or a disease. Indeed, making the diagnosis is essential for hormonal disease or genetic overgrowth syndromes...

Previous data have suggested that B-cell-depletion therapy may induce the settlement of autoreactive long-lived plasma cells (LLPCs) in the spleen of patients with autoimmune cytopenia. To investigate this process, we used the AID-CreERT2-EYFP mouse model to follow PCs engaged in an immune response. Multiplex-PCR at the single-cell level revealed that only a small fraction of splenic PCs had a long-lived signature, whereas PCs present after anti-CD20 antibody treatment appeared more mature, similar to bone-marrow PCs...

With the large amount of attention being given to microplastics in the environment, several researchers have begun to consider the fragmentation of plastics down to lower scales (i.e., the sub-micrometer scale). The term "nanoplastics" is still under debate, and different studies have set the upper size limit at either 1000 nm or 100 nm. The aim of the present work is to propose a definition of nanoplastics, based on our recently published and unpublished research definition of nanoplastics. We define nanoplastics as particles unintentionally produced (i...

Aim: The purpose of the present study was to investigate the role of endogenous Shh in ischemia-induced angiogenesis. Methods and results: To this aim, we used inducible Shh knock-out (KO) mice and unexpectedly found that capillary density was significantly increased in regenerating muscle of Shh deficient mice 5 days after hind limb ischemia (HLI) was induced, demonstrating that endogenous Shh does not promote angiogenesis but more likely limits it. Myosin and MyoD expression were equivalent in Shh deficient mice and control mice, indicating that endogenous Shh is not required for ischemia-induced myogenesis...
