Human Oncostatin M deficiency underlies an inherited severe bone marrow failure syndrome.

Oncostatin M (OSM) is a cytokine with the unique ability to interact with both the OSM receptor (OSMR) and the leukemia inhibitory factor receptor (LIFR). On the other hand, OSMR interacts with IL31RA to form the interleukin-31 receptor. This intricate network of cytokines and receptors makes it difficult to understand the specific function of OSM.

Incidence and risk factors of graft failure in allogeneic hematopoietic stem cell transplantation for mucopolysaccharidosis in a nationwide pediatric cohort. A study on behalf of the Francophone Society of Bone Marrow Transplantation and Cellular Therapy.

Context: Mucopolysaccharidosis (MPS) requires urgent treatment to prevent neurological damage. While gene therapy holds promise for effectively treating these diseases with minimal toxicity, access remains limited for most patients. Consequently, advancing allogeneic hematopoietic stem cell transplantation (HSCT) for young children is crucial.

Asymmetric Synthesis of β-Ketoamides by Sulfonium Rearrangement.

The synthesis of enantioenriched α-substituted 1,3-dicarbonyls remains a contemporary challenge in synthesis due to their tendency to undergo racemization via keto-enol tautomerization. Herein, we report a method to access enantioenriched β-ketoamides by a chiral sulfinimine-mediated [3,3]-sigmatropic sulfonium rearrangement. The transformation displays good chirality transfer, as well as excellent chemoselectivity and functional group tolerance.

[Clinical and transversal competencies of advanced practice nurses (APNs) within a cellular therapy team (SFGM-TC)].

The advanced practice nurse (APN) has been introduced in France, following the 2016 health law and implementing decrees published in 2018. In this context, the French Society for Bone Marrow Transplantation and Cellular Therapy (SFGM-TC) has already issued guidelines regarding the allocation of APNs' new clinical competences and their collaboration with physicians. It is now providing new recommendations on the transversal activities that can be fulfilled by APNs, such as research, leadership, training and teaching.
