RESUMO
OBJECTIVES: In the post-SARS-CoV-2 pandemic era, "breakthrough infections" are still documented, due to variants of concerns (VoCs) emergence and waning humoral immunity. Despite widespread utilization, the definition of the anti-Spike (S) immunoglobulin-G (IgG) threshold to define protection has unveiled several limitations. Here, we explore the advantages of incorporating T-cell response assessment to enhance the definition of immune memory profile. METHODS: SARS-CoV-2 interferon-gamma release assay test (IGRA) was performed on samples collected longitudinally from immunocompetent healthcare workers throughout their immunization by infection and/or vaccination, anti-receptor-binding domain IgG levels were assessed in parallel. The risk of symptomatic infection according to cellular/humoral immune capacities during Omicron BA.1 wave was then estimated. RESULTS: Close to 40% of our samples were exclusively IGRA-positive, largely due to time elapsed since their last immunization. This suggests that individuals have sustained long-lasting cellular immunity, while they would have been classified as lacking protective immunity based solely on IgG threshold. Moreover, the Cox regression model highlighted that Omicron BA.1 circulation raises the risk of symptomatic infection while increased anti-receptor-binding domain IgG and IGRA levels tended to reduce it. CONCLUSION: The discrepancy between humoral and cellular responses highlights the significance of assessing the overall adaptive immune response. This integrated approach allows the identification of vulnerable subjects and can be of interest to guide antiviral prophylaxis at an individual level.

BACKGROUND: Regional Centers for Occupational and Environmental Pathologies (CRPPE) are responsible for identifying possible occupational etiologies of pathologies. When an occupational origin is determined, an Initial Medical Certificate (IMC) is given to the patient to allow him to initiate a procedure for recognition as an occupational disease (OD) by his health insurance organization. OBJECTIVES: The main aim of this study was to investigate the outcome of occupational disease claims in patients who received an IMC delivered by the CRPPE of Lyon. METHODS: A telephone interview was systematically conducted with patients who consulted the CRPPE for a claim for occupational disease recognition between 07/2020 and 06/2021, about six months after the consultation. It was conducted by a physician using a standardized questionnaire. RESULTS: Out of 128 patients eligible for this study, 98 were included. Diseases of the respiratory system (34.7%) and cancers (28.6%) were the most common pathologies in our population. A process of OD compensation was initiated by 86 patients (87.8%). At the time of the study, the outcome was favorable for 63 patients (73.3%). Moreover, 18 patients (18.4%) wished for additional help from the CRPPE to carry out the procedures. Nine patients requested a new consultation, including five who still needed to complete the process. CONCLUSION: This study shows the benefit of a consultation by occupational disease consultants. However, difficulties still need to be solved in these procedures. Thus, the systematic follow-up of patients shows its advantages. The provision of support to carry out the process seems necessary.

Addressing health challenges that impact human well-being requires a comprehensive, interdisciplinary approach that would be at the crossroad of population-based prevention and individual-level clinical care, which is in line with a Global Health perspective. In the absence of a unifying theoretical framework to guide such interventions, a Dynamic Ecosystem Adaptation through the Allostasis (DEA-A) framework has been proposed, emphasizing the functional adaptation of individuals and organizations in symbiosis with their living ecosystem. While a conceptual model has been presented, this methodological contribution aims at illustrating the practical application of the DEA-A framework for planning Global Health interventions. The methodology combines Intervention Mapping and Cognitive and Behavioral Theory, extended to the ecosystem. Practical guidelines and supporting tools are provided to help public health providers and clinicians in establishing a functional ecosystem diagnosis of the issue; defining not only behavioral, but also emotional and cognitive change objectives (allostasis targets) expected for each stakeholder; and designing intervention plans targeting determinants of these allostasis. The discussion addresses implementation and evaluation perspectives of interventions based on the DEA-A framework, emphasizing the importance of considering change in its processual and ecosystem complexity. Lastly, encouragements for a deeper understanding of individual and ecosystem homeostasis/allostasis processes are made in order to promote more functional interventions.

Introduction: The mental health of residents is a growing significant concern, particularly with respect to hospital and university training conditions. Our goal was to assess the professional, academic, and psychological determinants of the mental health status of all residents of the academy of Lyon, France. Materials and methods: The Health Barometer of Lyon Subdivision Residents (BASIL) is an initiative which consists in proposing a recurrent online survey to all residents in medicine, pharmacy, and dentistry, belonging to the Lyon subdivision. The first of these surveys was conducted from May to July 2022. Participants should complete a series of validated questionnaires, including the Warwick-Edinburgh Mental Wellbeing Scale (WEMWBS), and the Kessler Psychological Distress Scale (K6), respectively, and ad-hoc questions assessing their global health and hospital and academic working conditions. A Directed Acyclic Graph (DAG) analysis was conducted prior to multivariable analyses, to explore the determinants associated with low wellbeing (WEMWBS <43) and high psychological distress (K6 ≥ 13). Results: A total of 904 residents (response rate: 46.7%) participated in the survey. A low level of wellbeing was observed in 23% of participants, and was significantly associated to job strain (OR = 2.18; 95%CI = [1.32-3.60]), low social support (OR = 3.13; 95%CI = [2.05-4.78]) and the experience of very poor university teaching (OR = 2.51; 95%CI = [1.29-4.91]). A high level of psychological distress was identified for 13% of participants, and associated with low social support (OR = 2.41; 95%CI = [1.48-3.93]) and the experience of very poor university teaching (OR = 2.89, 95%CI = [1.16-7.21]). Conclusion: Hospital working conditions, social support, and the perception of teaching quality, were three major determinants of wellbeing and psychological distress among health profession residents. Demographic determinants, personal life and lifestyle habits were also associated. This supports a multilevel action in prevention programs aiming to enhance wellbeing and reduce mental distress in this specific population and local organizational specificities.
RESUMO
PURPOSE: Return to work (RTW) is important for quality of life after breast cancer but its analysis at the population-level remains limited in France. This study aimed to implement Electronic Healthcare Data (EHD)-based indicators and trajectories to measure RTW after breast cancer diagnosis, and to examine stakeholders' perspectives regarding these indicators. METHODS: We followed a mixed-methods approach that consisted of (i) implementing RTW indicators and identifying clusters of trajectories using state sequence analysis with data from a representative sample of the French National Health Data System and (ii) exploring, through qualitative focus group and interviews, stakeholders' perceptions on the interpretation, limitations, and utility of these indicators. RESULTS: We extracted data from 317 women aged 25-55 years with a first diagnosis of early-stage breast cancer. The median number of sickness absence periods was 2 for a total of 434 days during the 3-year follow-up, and the median time to sustainable RTW was 240 days. Three clusters of RTW trajectories were identified: "early RTW" (49.5% of the population), "RTW after partial resumption" (37.5%) and "continuous compensation" (12.9%). Feedback from stakeholders highlighted the multi-factorial nature of RTW and underscored the added value of EHD for studying RTW, despite certain limitations. CONCLUSIONS: We demonstrated the feasibility of calculating RTW indicators and identifying trajectories using the French National Health Data System. These indicators can serve as outcome measures in RTW promotion and provide a basis for designing targeted interventions for breast cancer survivors.
