Background: The immediate postoperative period following heart surgery poses a substantial risk of life-threatening complications notably acute pulmonary and cardiac failure. Non-invasive ventilation (NIV) use may reduce the incidence of pulmonary and/or heart failure.

Research Question: Is the use of NIV before and after cardiac surgery associated with a lower rate of acute pulmonary and heart failure in patients at risk for post-operative complications?

Study Design And Methods: We designed a prospective, randomized, monocentric trial comparing pre- and post-operative NIV in cardiac surgery to standard care.

Network approaches to psychopathology have become increasingly common in mental health research, with many theoretical and methodological developments quickly gaining traction. This article illustrates contemporary practices in applying network analytical tools, bridging the gap between network concepts and their empirical applications. We explain how we can use graphs to construct networks representing complex associations among observable psychological variables.

Article Synopsis
  • Depression was a significant public health issue even before the Covid-19 pandemic, with a 2021 national study in France showing a 25% prevalence of major depressive disorder (MDD) among medical students and residents.
  • A survey conducted in 2021 revealed that only 32% of those who experienced MDD received adequate treatment, with only 20% receiving the recommended pharmacotherapy.
  • Factors like being further along in their medical studies and receiving care from both a general practitioner and a psychiatrist were linked to better treatment outcomes, highlighting the need for improved interventions to address MDD in medical students and residents.

Psychiatric disorders are common and can cause psychological disabilities. While the creation of day hospitals (DHs) was intended to direct psychiatric care towards community settings, they may have paradoxically contributed to a form of chronicity. Furthermore, the heterogeneity and lack of evaluation of care within DHs prevent the availability needed to collect objective data on users outcomes.

Background: Knowledge of premorbid glenoid parameters at the time of shoulder arthroplasty, such as inclination, version, joint line position, height, and width, can assist with implant selection, implant positioning, metal augment sizing, and/or bone graft dimensions. The objective of this study was to validate a scapular statistical shape model (SSM) in predicting patient-specific glenoid morphology in scapulae with clinically relevant glenoid erosion patterns.

Methods: Computed tomography scans of 30 healthy scapulae were obtained and used as the control group.

Background: The etiology of humeral posterior subluxation remains unknown, and it has been hypothesized that horizontal muscle imbalance could cause this condition. The objective of this study was to compare the ratio of anterior-to-posterior rotator cuff and deltoid muscle volume as a function of humeral subluxation and glenoid morphology when analyzed as a continuous variable in arthritic shoulders.

Methods: In total, 333 computed tomography scans of shoulders (273 arthritic shoulders and 60 healthy controls) were included in this study and were segmented automatically.

Article Synopsis
  • The study aimed to investigate the potential link between muscle imbalances and humeral posterior subluxation in arthritic shoulders by comparing the volumes of rotator cuff muscles and deltoids in patients with different glenoid types.
  • A total of 333 CT scans were analyzed to measure muscle volume ratios, but no significant differences or correlations were found between muscle ratios and glenoid morphology/humeral subluxation in the arthritic shoulder group.
  • However, a notable finding was that the AP ratio for type A glenoids was higher compared to type B and C glenoids, highlighting some moderate correlations between these muscle ratios and glenoid positioning across both health statuses.

Background: Social restrictions and their possible impact on lifestyle make people with multimorbidity (≥2 co-existing chronic conditions) more vulnerable to poor perceived mental health and health behaviours modifications during the COVID-19 pandemic.

Objective: To understand the mental health status and health behaviour modifications among individuals with multimorbidity during different levels of COVID-19 social restrictions.

Methods: Longitudinal multinational cohort study consisting of two online questionnaires with its first wave taken place while social restrictions were imposed (May 2020), and its second wave with less social restrictions in place (November 2020).

Article Synopsis
  • The study investigates exercise dependence, referred to as problematic physical activity (PPA), highlighting challenges in its theoretical and methodological frameworks.
  • Using confirmatory factor analysis (CFA) and a bifactor model, researchers analyzed the French version of the Exercise Dependence Scale-Revised (EDS-R) among 435 selected students to determine its dimensional structure.
  • Findings suggest that most items on the EDS-R are better indicators of a general exercise dependence factor, with withdrawal being identified as a distinct sub-dimension, contributing to ongoing discussions around behavioral addiction and how to conceptualize exercise dependence.

Article Synopsis
  • Total shoulder arthroplasty (TSA) seeks to restore the anatomy of a damaged shoulder, and this study investigates whether healthy shoulders can serve as a template by examining the symmetry of anatomical features between left and right shoulders in healthy individuals aged 18 to 50.
  • The research analyzed 130 pairs of healthy shoulder CT scans, measuring various glenoid and scapular dimensions, finding statistically significant differences in some aspects like glenoid version and inclination, but not in glenoid height.
  • Despite the observed differences, the overall similarity between the left and right shoulders suggests that healthy contralateral scapulae can be reliably used for surgical planning in TSA, with strong correlations between comparable measurements.

Physical activity (PA) is recommended to optimize well-functioning in people with schizophrenia. PA has been found to improve quality of life, general symptomatology, depression, anxiety and stress symptoms, global and social functioning. In PA research, most of the interventions are based on one-on-one interventions but there is poor information about group-based PA interventions.

Background: The mental health of health students is considered a public health issue which increased dramatically with the COVID 19's pandemic. Few studies have assessed the prevalence of depression in medical, pharmacy, and dental students. Our goal was to assess mental health in health students from the same university and identify the associated factors.

Introduction: The duration of untreated psychosis has been largely associated with poor outcomes in psychosis. Actual diagnostic tools may be used by very specialized teams and need sustained evaluation. We present a French version of a self-report questionnaire: the 16-item Prodromal Questionnaire (fPQ16).

Mental health represents a high cost for society, estimated at 109 billion euros per year in France, 80 % of which are indirect costs. Mental diseases start before the age of 24 for 75 % of patients. Students, whose age is predominantly between 18 and 25, are a particularly high-risk population and for whom mental illness can have very serious consequences.

Purpose: Treatment adherence is crucial in patients with rheumatoid arthritis (RA). The device used by the patients for self-injections may influence adherence to methotrexate (MTX) treatment. A MTX-autoinjector has been recently marketed in Europe.

Background And Context: Problematic use of physical activity is frequent in subjects with anorexia nervosa (AN). Although it increases resistance to therapeutic treatment, paradoxically, physical activity in AN can also improve mental and physical health. Based on the literature review we hypothesized that adding an adapted physical activity (APA) program to treatment programs could be more beneficial than a total suppression of physical activities.

Article Synopsis
  • The study investigates the prevalence of probable psychiatric disorders in the workforce and assesses how work-related psychosocial risk factors (PSRFs) contribute to these disorders.
  • Involved 3,200 participants from the French working population, it found a 22.2% prevalence of probable psychiatric disorders, with significant associations identified for ten PSRFs.
  • The strongest link was related to difficulties managing professional and personal responsibilities, with other notable associations including lack of support from colleagues and feeling fearful at work.
