Integrated Pediatric Intensive Care and Hematopoietic Stem Cell Transplantation Service Improves The Peri-Transplant Survival In Children.

Background: Peri-transplant is a critical period which is associated with a myriad of complications that require pediatric intensive care unit (PICU) referral. PICU outcomes have been historically poor post-hematopoietic stem cell transplantation (HSCT), especially when associated with inotrope support, invasive ventilation, and renal replacement therapy. The study aimed to assess the outcomes of PICU referral in children undergoing HSCT.

Volumetric imaging of the 3D orientation of cellular structures with a polarized fluorescence light-sheet microscope.

Polarized fluorescence microscopy is a valuable tool for measuring molecular orientations in biological samples, but techniques for recovering three-dimensional orientations and positions of fluorescent ensembles are limited. We report a polarized dual-view light-sheet system for determining the diffraction-limited three-dimensional distribution of the orientations and positions of ensembles of fluorescent dipoles that label biological structures. We share a set of visualization, histogram, and profiling tools for interpreting these positions and orientations.

ECM-dependent regulation of septin 7 in focal adhesions promotes mechanosensing and functional response in fibroblasts.

Fibroblasts are adherent cells that maintain tissue homeostasis by sensing and responding to the extracellular matrix (ECM). Focal adhesions (FAs) link these ECM changes to actomyosin dynamics through changes in its composition, influencing cellular response. Septin-7 (Sept-7) has previously been found in FA proteomics studies and shown to influence ECM sensing.

Haploidentical hematopoietic stem cell transplantation with post-transplant cyclophosphamide for Fanconi anemia with/without anti-thymocyte globulin.

Background: We present comparative data of children with Fanconi anemia undergoing haploidentical hematopoietic stem cell transplantation (HSCT) with or without the addition of rabbit anti-thymocyte globulin (r-ATG) to the conditioning regimen.

Patients And Methods: This retrospective study included children with Fanconi anemia aged up to 18 years who underwent haploidentical HSCT between January 2015 and December 2022. The children were included in two cohorts in this study.
