Genetic ancestry superpopulations show distinct prevalence and outcomes across pediatric central nervous system tumors from the PBTA and PNOC.

Background: Central nervous system (CNS) tumors lead to cancer-related mortality in children. Genetic ancestry-associated cancer prevalence and outcomes have been studied, but is limited.

Methods: We performed genetic ancestry prediction in 1,452 pediatric patients with paired normal and tumor whole genome sequencing from the Open Pediatric Cancer (OpenPedCan) project to evaluate the influence of reported race and ethnicity and ancestry-based genetic superpopulations on tumor histology, molecular subtype, survival, and treatment.

Humanizing processes after harm part 1: patient safety incident investigations, litigation and the experiences of those affected.

Background: There is a growing international policy focus on involving those affected by healthcare safety incidents, in subsequent investigations. Nonetheless, there remains little UK-based evidence exploring how this relates to the experiences of those affected over time, including the factors influencing decisions to litigate.

Aims: We aimed to explore the experiences of patients, families, staff and legal representatives affected by safety incidents over time, and the factors influencing decisions to litigate.

Humanising processes after harm part 2: compounded harm experienced by patients and their families after safety incidents.

Background: Healthcare organisations risk harming patients and their families twofold. First, through the physical, emotional and/or financial harm caused by safety incidents themselves, and second, through the organisational response to incidents. The former is well-researched and targeted by interventions.

multimutants enable efficient identification of SPI-2 effector protein function in gut inflammation and systemic colonization.

enterica spp. rely on translocation of effector proteins through the SPI-2 encoded type III secretion system (T3SS) to achieve pathogenesis. More than 30 effectors contribute to manipulation of host cells through diverse mechanisms, but interdependency or redundancy between effectors complicates the discovery of effector phenotypes using single mutant strains.

Average Age of Resuscitation Blood Products Is not Associated With In-Hospital Mortality Among Trauma Patients: A Retrospective Cohort Study.

Introduction: Transfusion of packed red blood cells (PRBC) or low-titer group O whole blood (LTOWB) has become standard practice in trauma patients with significant blood loss. As blood ages, it undergoes metabolic and structural changes. This study aimed to test the association between age of PRBC/LTOWB and mortality among adult trauma patients.
