Multiomics dissection of human RAG deficiency reveals distinctive patterns of immune dysregulation but a common inflammatory signature.

Human recombination-activating gene (RAG) deficiency can manifest with distinct clinical and immunological phenotypes. By applying a multiomics approach to a large group of -mutated patients, we aimed at characterizing the immunopathology associated with each phenotype. Although defective T and B cell development is common to all phenotypes, patients with hypomorphic variants can generate T and B cells with signatures of immune dysregulation and produce autoantibodies to a broad range of self-antigens, including type I interferons.

Variations and Opportunities in Postnatal Management of Hemolytic Disease of the Fetus and Newborn.

Importance: Preventive efforts in pregnancy-related alloimmunization have considerably decreased the prevalence of hemolytic disease of the fetus and newborn (HDFN). International studies are therefore essential to obtain a deeper understanding of the postnatal management and outcomes of HDFN. Taken together with numerous treatment options, large practice variations among centers may exist.

Spinal Anesthesia in Elderly Patients With Femoral Neck Fractures on Apixaban Therapy: A Case Series.

This case series reviews surgeries involving elderly patients with femoral neck fractures on apixaban who underwent spinal anesthesia (SA) within 72 hours of their last dose. Despite patients being on anticoagulation, no neurological complications occurred, suggesting SA may be practical in cases where the benefits of timely surgery outweigh the potential risks, including apixaban discontinuation for a period of less than the recommended 72 hours with detectable levels of the drug remaining in the plasma. Quantitative apixaban measurements offered useful anticoagulation status insights, though safe thresholds remain undefined.

A pan-tumor review of the role of poly(adenosine diphosphate ribose) polymerase inhibitors.

Poly(adenosine diphosphate ribose) polymerase (PARP) inhibitors, such as olaparib, talazoparib, rucaparib, and niraparib, comprise a therapeutic class that targets PARP proteins involved in DNA repair. Cancer cells with homologous recombination repair defects, particularly BRCA alterations, display enhanced sensitivity to these agents because of synthetic lethality induced by PARP inhibitors. These agents have significantly improved survival outcomes across various malignancies, initially gaining regulatory approval in ovarian cancer and subsequently in breast, pancreatic, and prostate cancers in different indications.

Do SGLT2 Inhibitors Protect the Kidneys? An Alternative Explanation.

SGLT2 inhibitors are a family of drugs that were developed to treat diabetes mellitus. In randomized controlled trials, SGLT2 inhibitors seem to prevent kidney deterioration in patients with nephropathies, both diabetic and non-diabetic. However, in contrast to biochemical/physiological results (proteinuria and serum creatinine levels) that improve in all studies, the clinical results (all-cause mortality, cardiovascular death, need for dialysis, or renal transplant) do not consistently improve.

Black posterior vitreous detachment: A 10-year historical cohort of pigmented uveal tumors.

Objective: Pigmentary posterior vitreous detachment (PVD), referred to as "black PVD," is a rare entity describing PVD along with pigment dispersion in the vitreous. There are a few case reports describing pigmentary PVD, yet the association between pigmentary PVD and uveal and optic disc tumors was not described before. The aim of this study was to report the clinical features of patients with pigmentary PVD associated with these tumors.

Severe neonatal hypotonia due to variant affecting function of ZnT5 zinc transporter.

The tightly-regulated spatial and temporal distribution of zinc ion concentrations within cellular compartments is controlled by two groups of Zn transporters: the 14-member ZIP/SLC39 family, facilitating Zn influx into the cytoplasm from the extracellular space or intracellular organelles; and the 10-member ZnT/SLC30 family, mobilizing Zn in the opposite direction. Genetic aberrations in most zinc transporters cause human syndromes. Notably, previous studies demonstrated osteopenia and male-specific cardiac death in mice lacking the ZnT5/ zinc transporter, and suggested association of two homozygous frameshift variants with perinatal mortality in humans, due to hydrops fetalis and hypertrophic cardiomyopathy.

Digital light processing printing of non-modified protein-only compositions.

This study explores the utilization of digital light processing (DLP) printing to fabricate complex structures using native gelatin as the sole structural component for applications in biological implants. Unlike approaches relying on synthetic materials or chemically modified biopolymers, this research harnesses the inherent properties of gelatin to create biocompatible structures. The printing process is based on a crosslinking mechanism using a di-tyrosine formation initiated by visible light irradiation.

Maintenance treatment with vedolizumab in paediatric inflammatory bowel disease (VEDOKIDS): 54-week outcomes of a multicentre, prospective, cohort study.

Background: Infliximab and adalimumab are the only biologics thus far approved for paediatric patients with inflammatory bowel disease (IBD), so other biologics, such as vedolizumab, are prescribed off-label. Despite its frequent use, prospective data for vedolizumab treatment in children are available only for short-term induction outcomes. We aimed to evaluate the long-term efficacy and safety of maintenance therapy with vedolizumab in paediatric patients with IBD.

Long-read structural and epigenetic profiling of a kidney tumor-matched sample with nanopore sequencing and optical genome mapping.

Carcinogenesis often involves significant alterations in the cancer genome, marked by large structural variants (SVs) and copy number variations (CNVs) that are difficult to capture with short-read sequencing. Traditionally, cytogenetic techniques are applied to detect such aberrations, but they are limited in resolution and do not cover features smaller than several hundred kilobases. Optical genome mapping (OGM) and nanopore sequencing [Oxford Nanopore Technologies (ONT)] bridge this resolution gap and offer enhanced performance for cytogenetic applications.

Machine learning-based prediction of disease progression in primary progressive multiple sclerosis.

Primary progressive multiple sclerosis (PPMS) affects 10-15% of multiple sclerosis patients and presents significant variability in the rate of disability progression. Identifying key biological features and patients at higher risk for fast progression is crucial to develop and optimize treatment strategies. Peripheral blood cell transcriptome has the potential to provide valuable information to predict patients' outcomes.
