Estimation of the relative effectiveness and waning of the monovalent third dose of COVID-19 vaccine against hospital admission in France: a novel self-controlled case series analysis.

We present a novel application of the SCCS method for estimating the effectiveness and waning of the third dose of COVID-19 monovalent vaccine in France. We used data on individuals hospitalised for COVID-19 between September 2021 and February 2022 from the Système National des D...

Should We Still Care About the Child and Adolescent Mental Health Services (CAMHS) to Adult Mental Health Services (AMHS) Transition? Evidence From a Systematic Review and Meta-Analysis

Objective Transition from Child and Adolescent Mental Health Services (CAMHS) to Adult Mental Health Services (AMHS) represents a vulnerable period for transitional age youth (TAY), with high risk of disengagement and unmet needs. Evidence on effective transition models remains l...

Palliative and end-of-life care on the battlefield: a scoping review

Abstract Background Modern conflicts have brought about a paradigm shift in military medicine. In Prolonged Field Care, recommendations have so far focused on damage control and care aimed at ensuring survival. But, particularly in large scale combat operation, not all patients w...

Measuring children’s HRQoL via self-reports and parent proxy-reports in the French Enabee 2022 study: an evaluation of the psychometric properties of both versions of the French KINDL-R questionnaire

Child well-being policies require quality data that takes children’s perspectives into account, recorded through appropriate, accurate and reliable measurement instruments. This study evaluated the psychometric properties of two versions of the KINDL-R questionnaire used in the 2...

Re-schooling as a major outcome of « therapeutic and schooling » programs for adolescents with obesity

Background School absenteeism is a frequent but underrecognized consequence of adolescent obesity, with long-term implications for social and professional integration. Objectives To assess changes in school attendance among adolescents with complex obesity before and after partic...

Lifetime exposure to atypical working hours among healthcare professionals compared with the workforce in other sectors: Nationwide cohort study

Background Despite well-documented health risks, cumulative exposure to atypical working hours (AWH) over a career remains poorly quantified, especially among healthcare workers. Objectives This study aimed to compare career-long AWH exposure among healthcare professionals and ot...

Randomized phase III trial with a factorial design assessing the efficacy and safety of darolutamide and stereotactic dose-escalated radiotherapy in patients with high-risk localized prostate cancer: the PEACE 7 (GETUG-AFU 45) study protocol

Approximately 15% of patients with localized prostate cancer harbor high risk features. Nowadays, the standard of care for such patients is the combination of androgen deprivation therapy (ADT) plus radiotherapy (hypofractionated or conventional dose escalated radiotherapy). A su...

Generational changes in lung function in adults from several world regions: results from the Burden of Obstructive Lung Disease study

This study estimated birth cohort effects on lung function using BOLD (Burden of Obstructive Lung Disease) data from 28 569 adults born between 1902 and 1976 across 41 sites in 34 countries. Forced vital capacity (FVC), forced expiratory volume in 1 s (FEV 1 ) and the FEV 1 /FVC...

The NPIS model: a consensus-based framework for evaluating non-pharmacological interventions

The term non-pharmacological intervention (NPI) refers to health prevention and care protocols supervised by healthcare professionals. However, no precise and widely adopted definition currently exists. Additionally, unlike drugs, NPIs do not have a global evaluation framework be...

Research Study Attrition and Participant-Informed Retention Strategies Among Cancer Survivors

Importance Attrition in longitudinal cancer cohorts compromises data completeness, introduces bias, and limits generalizability. Objective To quantify nonresponsiveness over time in a contemporary cohort of cancer survivors, identify individual- and center-level factors associate...

Association of cryptic pregnancy and alcohol consumption with fetal alcohol spectrum disorder: a nationwide population-based study of 5 million women in 2015–2022

Cryptic pregnancy (CP) also known as pregnancy denial remains an underexplored risk factor for FASD. To our knowledge, there is no available epidemiologic data in the scientific literature exploring the association between CP and FASD. This study aimed to examine the association...

Longitudinal evidence for decreasing statistical learning abilities across childhood

Abstract Statistical learning enables us to identify patterns in our environment and predict future events, thereby supporting a range of motor, cognitive, and linguistic skills. Despite its significance, the developmental trajectory of statistical learning has remained unclear d...

Cost-utility study of cognitive-behavioural management of auditory hallucinations in schizophrenia: a study protocol

Abstract Background Auditory verbal hallucinations (AVHs) affect 60–80% of patients with schizophrenia, causing significant distress and functional impairment. Although cognitive-behavioural therapy (CBT) has been shown to reduce AVH-related distress and relapse risk, its use rem...

Oral health, oral follow-up and infectious risk management of rheumatoid arthritis patients on anti-TNF drugs: a survey of a French e-cohort

Abstract Background As periodontitis is a recognized risk factor for rheumatoid arthritis (RA), it should be adequately treated before the initiation of biologic disease-modifying antirheumatic drugs (bDMARDs), along with any concomitant acute oral infection. bDMARDs remains a co...

Death determination at the bedside: clinical judgement beyond criteria

In clinical practice, death determination—a core responsibility of critical care clinicians—is commonly taught as the technical application of standardized medical and legal criteria. However, contemporary practices, including resuscitation, death determination by neurological cr...

The limitations of non-mechanistic methods for characterizing pathogen-pathogen interactions: A simulation study

Abstract Pathogen-pathogen interactions occur when infection with one pathogen influences one’s chance of infection or disease due to another. Increasingly, evidence suggests that interactions are a common feature of infectious disease epidemiology. However, due to both the nonli...

Prospective analysis of pre-diagnostic untargeted plasma metabolomics and risk of triple-negative breast cancer in the European Prospective Investigation into Cancer and Nutrition (EPIC)

Triple-negative breast cancer (TNBC) accounts for 10–15% of newly diagnosed breast cancer, and its aetiology is poorly understood compared to other breast cancer subtypes. We applied untargeted metabolomics to identify novel biological pathways associated with TNBC risk and poten...

Lost in Translation: Interprofessional Variability in Understanding Pro Re Nata (PRN) Prescribing in Geriatric Practice—A Prospective Observational Study

Background/Objectives: Medication safety is a critical concern in older adults due to age-related vulnerability, multimorbidity, and polypharmacy. Pro Re Nata (PRN, “as needed”) prescribing is common in geriatric care but may be interpreted inconsistently across healthcare profes...

Win ratio analysis of surgical approaches for lung cancer: a nationwide observational study using the French national hospital discharge database

Minimally invasive surgical approaches have gained widespread adoption, yet comparative evidence integrating multiple hierarchical endpoints remains limited. Our objective was to compare the surgical approaches for lung cancer resection (thoracotomy, VATS, robot-assisted surgery)...

Visible mould and blood inflammatory phenotypes of asthma in adults: the CONSTANCES cohort

Studying the associations between indoor mould contamination and blood inflammatory phenotypes may provide further insight into the mechanisms by which this environmental factor affects asthma. Among 1870 adults with current asthma from a population-based cohort, 29.6% reported v...
