Effectiveness and safety of biosimilars in pediatric inflammatory bowel diseases: an observational longitudinal study on the French National Health Data System.

Background: Data on biosimilar use in pediatric inflammatory bowel diseases (IBD) are scarce compared to the status of studies in adults, resulting in limitations in its treatment. We compared effectiveness and safety of biosimilars versus originators in this population.

Methods: We used data from the French National Health Data System to identify children (less than 18 years old at treatment initiation) initiating treatment with a biosimilar or the originator infliximab or adalimumab for Crohn's disease (CD) or ulcerative colitis (UC), from first biosimilar launch (January 2015 and October 2018, respectively) to 31 December 2022.

Computerized cognitive training for problem gambling: A randomized controlled trial (TRAIN-online).

Background: Non-face-to-face interventions offer promise, with cognitive training showing potential but inconsistent efficacy in problem gambling.

Methods: We conducted a non-face-to-face, parallel, randomized, controlled, single-blinded trial to evaluate training programs in adults with problem gambling (CPGI ≥5). Participants were randomized 1:1 to a web-based cognitive training program targeting inhibition unrelated to addiction cues or a control program on visuo-spatial functioning.

Characterization of an Activated Metabolic Transcriptional Program in Hepatoblastoma Tumor Cells Using scRNA-seq.

Hepatoblastoma is the most common primary liver malignancy in children, with metabolic reprogramming playing a critical role in its progression due to the liver's intrinsic metabolic functions. Enhanced glycolysis, glutaminolysis, and fatty acid synthesis have been implicated in hepatoblastoma cell proliferation and survival. In this study, we screened for altered overexpression of metabolic enzymes in hepatoblastoma tumors at tissue and single-cell levels, establishing and validating a hepatoblastoma tumor expression metabolic score using machine learning.

ADHD and alcohol: Emotional regulation efforts pay off in quality of life points.

The emotion dysregulation and impulsivity are highly associated with alcohol use disorder (AUD). This study explored the role of impulsivity and emotion dysregulation and the interaction with adult probable ADHD on alcohol-related quality of life (QoL). In this observational trial, we analyzed data from the randomized TRAIN study, which compared efficacy of two cognitive training programs in patients AUD recently detoxified at 5 centers in France from February 2019 to February 2023, and who completed child and adult ADHD screening data (WURS + ARSR, n = 206 of 226).

Metabolic Transcriptional Activation in Ulcerative Colitis Identified Through scRNA-seq Analysis.

Background: Ulcerative colitis is a chronic inflammatory disease affecting the colon. During chronic inflammation of epithelial cells, lipid metabolism via pro-inflammatory eicosanoids is known to modify the immune response.

Methods: Starting from the Mammalian Metabolic Database, the expression of metabolic enzymes was investigated in two independent cohorts from transcriptome datasets GSE38713 and GSE11223, which analyzed ulcerative colitis tissue samples from the digestive tract.

Anxiety, depression and fear of cancer recurrence in uveal melanoma survivors and ophthalmologist/oncologist communication during survivorship in France - protocol of a prospective observational mixed-method study.

Background: Quality of life (QoL) in patients undergoing surveillance for uveal melanoma (UM) can be affected by psychological sequelae. Fear of cancer recurrence (FCR) may be acute especially when prognostication indicates an increased risk of metastatic recurrence. Communication with an ophthalmologist or oncologist can then play a key role in impacting QoL.

Caesarean section scar: Histological analysis on hysterectomy specimen. A pilot study.

Introduction: In recent years, caesarean section (CS) rate has risen worldwide. Complications associated with CS scars have risen too, such as scar dehiscences and uterine ruptures. Uterine healing is a complex phenomenon still poorly understood.

Polygenic risk scores stratify breast cancer risk among women with benign breast disease.

Purpose: Most breast biopsies are diagnosed as benign breast disease (BBD), with 1.5- to fourfold increased breast cancer (BC) risk. Apart from pathologic diagnoses of atypical hyperplasia, few factors aid in BC risk assessment of these patients.

Trastuzumab Deruxtecan in Human Epidermal Growth Factor Receptor 2-Positive Metastatic Gastric Cancer in a Real-World Setting: A Nationwide Cohort Study.

Introduction: Trastuzumab deruxtecan (T-DXd) has been approved for human epidermal growth factor receptor 2-positive locally advanced or metastatic gastric and gastroesophageal junction (HER2+ mG/GEJ) cancer since July 2022 in France, through an accelerated approval. The aim of this study was to evaluate its real-world use.

Methods: We characterized T-DXd users treated for HER2+ mG/GEJ cancer using data from the French National Health Insurance database.

Enhanced heterologous gene expression in Trichoderma reesei by promoting multicopy integration.

Trichoderma reesei displays a high capability to produce extracellular proteins and therefore is used as a platform for the expression of heterologous genes. In a previous study, an expression cassette with the constitutive tef1 promoter and the cbh1 terminator compatible with flow cytometry analysis was developed. Independent transformants obtained by a random integration into the genome of a circular plasmid containing the expression cassette showed a wide range of fluorescence levels.

Influence of mRNA Covid-19 vaccine dosing interval on the risk of myocarditis.

Myocarditis is the most salient serious adverse event following messenger RNA-based Covid-19 vaccines. The highest risk is observed after the second dose compared to the first, whereas the level of risk associated with more distant booster doses seems to lie in between. We aimed to assess the relation between dosing interval and the risk of myocarditis, for both the two-dose primary series and the third dose (first booster).

Risk of heavy menstrual bleeding following COVID-19 vaccination: A nationwide case-control study.

Background: COVID-19 vaccination has been inconsistently associated with an increased risk of heavy menstrual bleeding in previous studies. This study aimed to assess the risk of heavy menstrual bleeding requiring hospital care following COVID-19 vaccination according to the number of doses received and the time elapsed since vaccination.

Methods: Using comprehensive data of the French National Health Data System, we carried out a case-control study.

Facilitating patient-oncologist communication in advanced treatment-resistant cancer: development and feasibility testing of a question prompt list.

Background: Patients' expectations regarding medical information in advanced stages of cancer are still poorly understood. Tailoring information to advanced cancer patients is a subtle task. We developed a question prompt list (QPL) that serves as a patient-oncologist communication aid in France.

Long-Term Prognosis of Patients With Myocarditis Attributed to COVID-19 mRNA Vaccination, SARS-CoV-2 Infection, or Conventional Etiologies.

Importance: Although patients with myocarditis after COVID-19 mRNA vaccination appear to have a good prognosis near hospital discharge, their longer-term prognosis and management remain unknown.

Objective: To study the cardiovascular complications of post-COVID-19 mRNA vaccination myocarditis and other types of myocarditis during an 18-month follow-up, as well as disease management based on a study of the frequency of medical procedures and drug prescriptions.

Design, Setting, And Participants: In this cohort study based on the French National Health Data System, all individuals aged 12 to 49 years hospitalized for myocarditis in France between December 27, 2020, and June 30, 2022, were identified.

Determinants and risk factors for renal damage: where do patients hospitalized for severe anorexia nervosa stand? A multi-center study.

Background: Although renal damage is increasingly reported among the most undernourished patients with Anorexia Nervosa (AN), it remains underestimated in current practice, and often associated with acute dehydration. The purpose of our study was to evaluate the frequency, the extent, and the risk factors of renal involvement among adolescents and adults hospitalized in specialized units for AN.

Methods: In this multi-center study, 197 consecutive participants were included, aged 13-65, from 11 inpatient eating disorder psychiatric units.

Risk factors for COVID-19 hospitalisation after booster vaccination during the Omicron period: A French nationwide cohort study.

Background: In spite of major effectiveness, a residual risk after COVID-19 primary vaccination was identified, in particular, for vulnerable individuals of advanced age or with comorbidities. Less is known about the Omicron period in people protected by a booster dose. We aimed to identify the characteristics associated with severe COVID-19 during the Omicron period in a population that had received a booster dose in France and to compare differences with the previous periods of the pandemic.

Relevance of individual bronchial symptoms for asthma diagnosis and control in patients with rhinitis: A MASK-air study.

Rationale: It is unclear how each individual asthma symptom is associated with asthma diagnosis or control.

Objectives: To assess the performance of individual asthma symptoms in the identification of patients with asthma and their association with asthma control.

Methods: In this cross-sectional study, we assessed real-world data using the MASK-air app.

Testosterone Reduces Myelin Abnormalities in the Wobbler Mouse Model of Amyotrophic Lateral Sclerosis.

Amyotrophic lateral sclerosis (ALS) is a fatal motoneuron degenerative disease that is associated with demyelination. The () mouse exhibits motoneuron degeneration, gliosis and myelin deterioration in the cervical spinal cord. Since male s display low testosterone (T) levels in the nervous system, we investigated if T modified myelin-relative parameters in s in the absence or presence of the aromatase inhibitor, anastrozole (A).

Reducing musculoskeletal disorders in iron ore mine operators: A fuzzy-based intervention approach.

Background: This study focuses on evaluating the exposure to whole-body vibration (WBV) and association of musculoskeletal disorders (MSDs) with various risk factors among dumper operators in the mining industry. Despite the issue's significance, prior research has been limited.

Objective: The study introduces a novel fuzzy-based approach for identifying, selecting, and prioritizing safety measures to mitigate MSD risks.

Targeting the TNF/IAP pathway synergizes with anti-CD3 immunotherapy in T-cell acute lymphoblastic leukemia.

T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematological malignancy. Current treatments, based on intensive chemotherapy regimens provide overall survival rates of ∼85% in children and <50% in adults, calling the search of new therapeutic options. We previously reported that targeting the T-cell receptor (TCR) in T-ALL with anti-CD3 (αCD3) monoclonal antibodies (mAbs) enforces a molecular program akin to thymic negative selection, a major developmental checkpoint in normal T-cell development; induces leukemic cell death; and impairs leukemia progression to ultimately improve host survival.

Uterine wound healing after caesarean section: A systematic review.

The rate of caesarean section (CS) is increasing worldwide. Defects in uterine healing have a major gynaecological and obstetric impact (uterine rupture, caesarean scar defect, caesarean scar pregnancy, placenta accreta spectrum). The complex process of cellular uterine healing after surgery, and specifically after CS, remains poorly understood in contrast to skin wound healing.

The relationship between negative life events and cortical structural connectivity in adolescents.

Adolescence is a crucial period for physical and psychological development. The impact of negative life events represents a risk factor for the onset of neuropsychiatric disorders. This study aims to investigate the relationship between negative life events and structural brain connectivity, considering both graph theory and connectivity strength.
