Better 10‐Year Cerebrovascular Outcome After Transplant Than on Standard‐Care in Sickle Cell Anemia: DREPAGREFFE Trial

American Journal of Hematology, Volume 101, Issue 8, Page 1799-1817, August 2026.
ABSTRACT Management of cerebral vasculopathy in sickle cell anemia (SCA) includes standard‐care, that is, chronic transfusion (CT) or hydroxyurea, and hematopoietic cell transplantation (HCT). DREPAGREFFE‐1 (December 2010/June 2013), a French multicenter trial, was the first prospective trial comparing standard‐care to match sibling donor (MSD)‐HCT in ...

Backrest Position and Outcome in Comatose Survivors of Out‐of‐Hospital Cardiac Arrest: Protocol for a Multi‐Center Randomized Comparison Within the Danish Out‐of‐Hospital Cardiac Arrest (DANOHCA) Trial

Acta Anaesthesiologica Scandinavica, Volume 70, Issue 7, August 2026.
ABSTRACT Background Intensive care following resuscitation from out‐of‐hospital cardiac arrest (OHCA) is based on a set of interventions, all of which are intended to reduce anoxic brain injury and improve outcomes, including sedation, mechanical ventilation, circulatory optimization, and temperature control protocols.

A 17 Year Old With Developmental Delay Presenting With Increasing Confusion and Imbalance

Annals of Clinical and Translational Neurology, Volume 13, Issue 7, Page 1518-1523, July 2026.
ABSTRACT Methylmalonic acidemia is an autosomal recessive genetic disorder primarily caused by defects in methylmalonyl‐CoA mutase and cobalamin (vitamin B12) metabolism. These defects disrupt the tricarboxylic acid cycle and oxidative phosphorylation, leading to the abnormal accumulation of metabolic products such as methylmalonic acid, propionic acid,

Transplant versus no transplant outcome in adolescents and adults with sickle cell disease eligible for allogeneic hematopoietic stem cell transplantation

HemaSphere, Volume 10, Issue 7, July 2026.
Abstract Hematopoietic stem cell transplantation (HSCT) remains the only curative option for sickle cell disease (SCD), but its use in adolescents and adults is limited by toxicity concerns. We evaluated the risk–benefit profile of HSCT in this population through a comparative analysis of transplant versus nontransplant strategies. HSCT was analyzed as
