Study of the cellular and humoral immune responses to SARS-CoV-2 vaccination.

Our understanding of cellular immunity in response to COVID-19 infection or vaccination is limited because of less commonly used techniques. We investigated both the cellular and humoral immune responses before and after the administration of a third dose of the SARS-CoV-2 vaccine among a group of healthcare workers. Cellular immunity was evaluated using the VIDAS interferon-gamma (IFNγ) RUO test, which enables automated measurement of IFNγ levels after stimulating peripheral blood lymphocytes.

Low performance of interferon gamma release assay Quantiferon-TB gold coupled or not with Pst1/3/lipoglycan humoral detection to predict Mycobacterium tuberculosis complex disease in a low-burden area.

Whole T cell interferon gamma release assays such as QuantiFERON-TB Gold Plus (QTF-TB) are used to evaluate Mycobacterium tuberculosis complex (MTC) exposure but fail to discriminate latent tuberculosis infection (LTBI) from active disease. In this study conducted in a low-burden area, 1215 patients presenting MTC risk and tested both for QTF-TB and mycobacterial infection (microscopy, culture, and/or PCR) were selected, as well as 1298 controls screened with QTF-TB before medical recruitment. The humoral response (LIODetect®TB-ST) was further evaluated in 199 selected patients.

Antibody Titers and Protection against Omicron (BA.1 and BA.2) SARS-CoV-2 Infection.

The emergence of the SARS-CoV-2 variants of concern has greatly influenced the immune correlates of protection, and there are little data about the antibody threshold concentrations to protect against infection with SARS-CoV-2 Omicron BA.1 or BA.2.

Decreased Efficiency of Neutralizing Antibodies from Previously Infected or Vaccinated Individuals against the B.1.617.2 (Delta) SARS-CoV-2 Variant.

The neutralizing antibody response is a key component of adaptive immunity and a primary protection against severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) infection. The increased transmissibility of the SARS-CoV-2 Delta variant and its capacity to cause more severe disease could be linked to a significant reduction in neutralizing antibodies generated during a previous infection or vaccination. We analyzed blood samples from 162 unvaccinated health care workers (HCWs) collected 1 to 3 months postinfection and from 263 vaccinated health care workers 1 month after the last injection.

Impact of the treatment of chronic myeloid leukaemia by tyrosine-kinase inhibitors on sick leaves refund: a nationwide cohort study.

Background: The advent of chronic myeloid leukaemia (CML) tyrosine-kinase inhibitors (TKI) has led to new paradigms including occupational rehabilitation.

Objectives: This study aimed to characterize the impact of CML treatment on sick leaves within the 2 years following diagnosis in working-age patients.

Methods: A cohort of all 18-60-year-old newly diagnosed CML patients initiating a TKI between January 1 2011 and December 31 2014 in France was identified in the French National Healthcare database (Système National des Données de Santé [SNDS]).

The real seroprevalence of SARS-CoV-2 in France and its consequences for virus dynamics.

The SARS-CoV-2 virus has spread world-wide since December 2019, killing more than 2.9 million of people. We have adapted a statistical model from the SIR epidemiological models to predict the spread of SARS-CoV-2 in France.

Development of a Questionnaire for the Search for Occupational Causes in Patients with Non-Hodgkin Lymphoma: The RHELYPRO Study.

Non-Hodgkin lymphoma (NHL), multiple myeloma and chronic lymphocytic leukemia are possibly related to environmental and/or occupational exposure. The primary objective of this study was to develop a questionnaire for screening patients with these blood disorders who might benefit from a specialized consultation for possible recognition of the disease as an occupational disease. The study included 205 subjects (male gender, 67.

[Compensation of damage in cancerology].

In a few situations, the consequences secondary to a carcinological pathology require an assessment of damages for compensatory purposes. This is particularly the case when liable parties have been found to be at cause of the disease: occupational pathologies in the case of inexcusable employer's fault, exposure to a radioactive risk, for example in the context of full compensation for damages suffered by the victims of nuclear experiments performed by France, or lastly, in the after-effects of late diagnosis. This article does not discuss the imputability of cancer pathologies to an event, but it proposes an adaptation of methods for assessing damages, in an attempt to provide full compensation for damages.

Evolution of medication consumption in a working environment in France: Results of the four waves of the "Drugs and Work" study (1986-2016).

Objectives: Previous studies in the working environment have underlined the high prevalence of drug consumption. The aim of this study was to present the main characteristics of this consumption in French workers and to identify changes from the 1986, 1996, 2006 and 2016 surveys.

Methods: The design was a repeated cross-sectional study in 1986, 1996, 2006 and 2016.

Barriers to seeking help for physicians with substance use disorder: A review.

Background: Substance use disorders (SUD) might concern as many as 8-15% of physicians. Previous studies suggest that self-diagnosis and self-medication are common practices among physicians. The aim of this review was to identify if barriers to seeking help and medical care for impaired physicians exist.

Lung cancer survivors and employment: A systematic review.

Background: The aim of this systematic review is to identify, in a comprehensive manner, the impact of lung cancer on the employment status of survivors.

Methods: The Preferred Reported Items for Systematic Reviews and Meta-analyses (PRISMA) statement was used as a formal guideline. The systematic review includes scientific papers published between January 2000 and October 2018.

Work adjustments and employment among breast cancer survivors: a French prospective study.

Purpose: The objective of our study was to assess the rate of work adjustments 1 year after the diagnosis in a population of female breast cancer (BC) survivors, in the context of the French system of social protection. We also characterised these adjustments and their influence on the reduction of professional exclusion of patients 1 year after the diagnosis.

Methods: This observational, prospective study was conducted from February 2015 to April 2016 among female patients with BC.

The impact of chronic myeloid leukemia on employment: the French prospective study.

Patients with chronic myeloid leukemia treated with breakpoint cluster region-Abelson tyrosine kinase inhibitors are likely to survive in excess of 20 years after diagnosis. New challenges appear as we consider life after the disease, including professional challenges and the social reintegration of patients. The purpose of this study was to determine the impact of chronic myeloid leukemia on employment within 2 years after diagnosis.
