Hormone therapy has a bigger impact than chemotherapy on women’s quality of life

Analysis of the CANTO cohort published in the journal Annals of Oncology will upset received wisdom on the effects that hormone therapy and chemotherapy have on the quality of life in women with breast cancer. Contrary to the commonly held view, 2 years after diagnosis, hormone therapy, a highly effective breast cancer treatment worsens quality of life to a greater extent and for a longer time, especially in menopausal patients. The deleterious effects of chemotherapy are more transient.

La science agit pour l’égalité homme/femme

Violetta Zujovic, chercheuse à l’Inserm et ses collègues du comité XX initative regroupés au sein de l’Institut du cerveau et de la moelle épinière (Inserm/CNRS/Sorbonne Université) à l’hôpital de la Pitié-Salpêtrière AP-HP, expliquent comment une approche neuroscientifique permet de lutter plus efficacement contre les inégalités femmes/hommes.

Lire les sons du langage : une aire du cerveau spécialisée dans la reconnaissance des graphèmes

Une étude a permis d’analyser les mécanismes de la lecture à l’œuvre chez les adultes. Les chercheurs ont identifié une région cérébrale du cortex visuel qui serait responsable de la reconnaissance des graphèmes, c’est-à-dire des lettres ou groupes de lettres transcrivant un son élémentaire de la langue parlée (phonèmes).

Assistance médicale à la procréation : la congélation embryonnaire associée à une augmentation du poids de naissance

Des équipes du CHU de Montpellier et de l’Inserm publient dans la revue Scientific Reports une étude portant sur une différence de poids de plus de 250 grammes entre les enfants nés à la suite d’une congélation embryonnaire et ceux issus d’embryons « frais ».

Atopic dermatitis: how allergens get on our nerves

Atopic dermatitis, or eczema, primarily affects infants and children, and manifests itself in hypersensitivity to allergens in the environment. A skin disease characterized by flare-ups, it is often treated with topical anti-inflammatories. A new study shows that immune cells and sensory neurons interact in the skin to form units that can detect allergens and trigger inflammation. A discovery that provides an insight into how atopic dermatitis works, and points the way to new therapeutic possibilities.

Dysentery: Shigella, bacteria with adaptation to respiration

Imagerie montrant la déplétion de l'oxygène au sein de la muqueuse intestinale par Shigella (vert), induisant une hypoxie (rouge) au sein des foyers infectieux inflammatoires (neutrophiles: marqués à l'aide du Myelotracker, bleu).

Bacillary dysentery caused by the intestinal bacteria Shigella is a major health problem in tropical regions and developing countries. Complications from this infection lead to several hundred thousand deaths a year, primarily among infants. Researchers from Inserm and the Institut Pasteur have studied the mechanisms of Shigella virulence. They found that these bacteria are not only able to consume the oxygen in colonic tissue in order to grow and create foci of infection, but can also adapt their mode of respiration so that they can continue to grow once the oxygen in these foci has been used up.

Identified: A Protein Essential for Chikungunya Virus Replication

Chikungunya is characterized by high fever and intense joint and muscle pain that can last for several months. The mechanisms of infection of human cells with the virus remain very poorly understood. Led by Ali Amara in collaboration with Marc Lecuit researchers from Inserm, Institut Pasteur, CNRS and Université de Paris have identified a protein that is crucial in order for the virus to replicate within its target cells.
