Background: In heart transplantation, antibody-mediated rejection (AMR) is a major contributor to patient morbidity and mortality. Multiple routine endomyocardial biopsies (EMB) remain the gold standard to detect AMR, but this invasive procedure suffers from many limitations. We aimed to develop and validate an AMR risk model to improve individual risk stratification of AMR.

Background: There is a paucity of epidemiological data on asthma classified by disease severity in France. The ASTHMAPOP cross-sectional study aimed to review the prevalence and current management of asthma in people aged ≥18 years in France.

Methods: A self-administered questionnaire was mailed to 19 676 people representative of the French population in age, gender, region, and socio-economic status.

Article Synopsis
  • The study focuses on cardiac allograft vasculopathy (CAV), a significant cause of mortality in heart transplant patients, aiming to identify different progression patterns of CAV and the factors influencing these trajectories.
  • Researchers monitored 1,301 heart transplant recipients from multiple academic centers, analyzing numerous angiographies and medical parameters to forecast CAV development and its association with patient mortality.
  • Four distinct CAV progression profiles were discovered: no CAV progression, late-onset slow progression, mild progression, and accelerated progression, with specific early predictors identified that could help in understanding and managing CAV in patients.

Early-life adversity is a major risk factor for the development of diseases later in life. Maternal protein restriction (MPR) is associated with morbidities in offspring affecting multiple organs, but its impact on the gastrointestinal (GI) tract remains poorly studied. Using a rat model, we examined the consequences of MPR on GI function and on the enteric nervous system (ENS) in the offspring at postnatal d 35 under basal state and following a water avoidance stress (WAS).

Background: Many people in Europe remain undiagnosed for human immunodeficiency virus (HIV), hepatitis B virus (HBV), hepatitis C virus (HCV).

Objectives: To evaluate acceptability and effectiveness of a questionnaire designed to facilitate identification of risk factors for these viruses.

Methods: We performed an observational study, in a prospectively enrolled cohort of patients in Paris (France) seen in 2014.

Background: The use of levothyroxine to treat subclinical hypothyroidism is controversial. We aimed to determine whether levothyroxine provided clinical benefits in older persons with this condition.

Methods: We conducted a double-blind, randomized, placebo-controlled, parallel-group trial involving 737 adults who were at least 65 years of age and who had persisting subclinical hypothyroidism (thyrotropin level, 4.

Article Synopsis
  • Antibody-mediated rejection (AMR) is a significant factor in heart transplant failure, but understanding its mechanisms and improving detection methods is crucial for better outcomes.
  • A study involving 617 heart transplant recipients examined AMR through various techniques, including histopathology, immunostaining, and gene expression profiling, comparing patients with and without AMR.
  • Results indicated that AMR is characterized by specific immune responses and changes in gene expression related to endothelial activation and inflammation, with distinct gene sets that could effectively differentiate between AMR and non-AMR patients.

Rationale: The role of circulating antibodies in addition to traditional cardiovascular risk factors in the development of accelerated arteriosclerosis and their long-term clinical consequences have not been demonstrated.

Objective: We investigated the role of circulating antibodies in accelerated arteriosclerosis and the role of immune-associated arteriosclerosis in graft and patient survival and the occurrence of major adverse cardiovascular events.

Methods And Results: This was an observational prospective cohort study that included 1065 kidney transplant patients (principal cohort, n=744; validation cohort, n=321) between 2004 and 2010.

Enteric glial cells (EGCs) are essential in the control of gastrointestinal functions. Although lesions of EGCs are associated with neuronal degeneration in animal models, their direct neuroprotective role remains unknown. Therefore, the aims of this study were to demonstrate the direct neuroprotective effects of EGCs and to identify putative glial mediators involved.

The nucleotide sequence was determined for a 9.4-kb region of Clostridium thermocellum DNA extending from the 3' end of the gene (now termed cipA), encoding the S1/SL component of the cellulosome. Three open reading frames (ORFs) belonging to two operons were detected.

12 carboxyl residues of the Clostridium thermocellum endoglucanase CelD were mutated to alanine. The specific activity of five of the mutated proteins was 1% or less that of wild type. The Ca2+ binding isotherms of these five were similar to those of wild type CelD, consistent with the fact that none of the mutated residues is observed to be directly involved in Ca2+ binding in the three-dimensional structure of the protein (Juy, M.
