The DNA damage response—Repair or despair?

The term “the DNA damage response” (DDR) encompasses a sophisticated array of cellular initiatives set in motion as cells are exposed to DNA-damaging events. It has been known for over half a century that all organisms have the ability to restore genomic integrity through DNA repair. More recent discoveries of signal transduction pathways linking DNA damage to cell cycle arrest and apoptosis have greatly expanded our views of how cells and tissues limit mutagenesis and tumorigenesis. DNA repair not only plays a pivotal role in suppressing mutagenesis but also in the reversal of signals inducing the stress response. If repair is faulty or the cell is overwhelmed by damage, chances are that the cell will despair and be removed by apoptosis. This final fate is determined by intricate cellular dosimeters that are yet to be fully understood. Here, key findings leading to our current view of DDR are discussed as well as potential areas of importance for future studies. Environ. Mol.

Biais inconscients et comportements inclusifs dans les organisations

Dans la foulée des revendications pour la prise en compte des inégalités et des discriminations envers les groupes historiquement et socialement marginalisés, nombreuses sont les organisations privées et publiques qui souhaitent se doter de plans, de politiques et de projets afin de transformer leurs pratiques organisationnelles en matière d’équité, de diversité et d’inclusion (EDI). Cette collection interdisciplinaire souhaite contribuer à alimenter ces changements dans les organisations en réunissant des ouvrages qui abordent différentes thématiques liées à l’EDI. Conformément à la mission de l’Institut EDI2 d’être un pôle d’expertise et de production de la connaissance en EDI, cette collection vise à faire connaître et à accompagner les personnes et les organisations de divers milieux dans leurs réflexions et leurs actions touchant à la fois les expériences individuelles et interrelationnelles et les pratiques de gestion. Cette collection réunit ainsi des ouvrages sous plusieurs axes d’intervention, tels que les concepts fondamentaux liés à l’EDI en milieu de travail, l’EDI au sein de différentes disciplines et divers secteurs d’activité, l’insertion et la rétention en emploi des groupes historiquement et socialement marginalisés dans une perspective intersectionnelle et les méthodologies et pratiques d’intervention en organisation dans toutes ses dimensions et dans une perspective de changement.

Racial and Ethnic Minorities at the Highest Risk of Uncontrolled Moderate-to-Severe Asthma: A United States Electronic Health Record Analysis

Aim of this study was to identify risk factors for uncontrolled asthma in United States cohort using electronic health record (EHR)-derived data.Patients and Methods: In this retrospective real-world study, de-identified data of adolescent and adult patients (≥ 12 years old) with moderate-to-severe asthma, based on asthma medications within 12 months prior to asthma-related visit (index date), were extracted from the Optum® Humedica EHR. The baseline period was 12 months prior to the index date. Uncontrolled asthma was defined as ≥ 2 outpatient oral corticosteroid bursts for asthma or ≥ 2 emergency department visits or ≥ 1 inpatient visit for asthma. A Cox proportional hazard model was applied.Results: There were 402,403 patients in the EHR between January 1, 2012, and December 31, 2018, who met the inclusion criteria and were analyzed. African American (AA) race (hazard ratio [HR]: 2.08), Medicaid insurance (HR: 1.71), Hispanic ethnicity (HR: 1.34), age of 12 to < 18 years (HR 1.20), body mass index of ≥ 35 kg/m2 (HR: 1.20), and female sex (HR 1.19) were identified as risk factors associated with uncontrolled asthma (P < 0.001). Comorbidities characterized by type 2 inflammation, including a blood eosinophil count of ≥ 300 cells/μL (as compared with eosinophil < 150 cells/μL; HR: 1.40, P < 0.001) and food allergy (HR: 1.31), were associated with a significantly higher risk of uncontrolled asthma; pneumonia was also a comorbidity associated with an increased risk (HR: 1.35) of uncontrolled asthma. Conversely, allergic rhinitis (HR: 0.84) was associated with a significantly lower risk of uncontrolled asthma.Conclusion: This large study demonstrates multiple risk factors for uncontrolled asthma. Of note, AA and Hispanic individuals with Medicaid insurance are at a significantly higher risk of uncontrolled asthma versus their White, non-Hispanic counterparts with commercial insurance.Keywords: asthma, underserved, uncontrolled, Medicai
