Hematopoietic stem cell transplant has been the single curative treatment for inborn errors of immunity (IEI) and is recommended for the most severe IEI conditions, such as severe combined immunodeficiency (SCID). However, adverse outcomes primarily due to histocompatibility differences between the donor and the patient are still of concern. Progress in genetic and molecular mechanisms, as well as new technology to insert DNA sequences in cell genomes has allowed the development of strategies to treat genetic diseases by correcting the gene defect in patients' cells.

Background: Genome-wide association studies have identified several hundred susceptibility single nucleotide variants for coronary artery disease (CAD). Despite single nucleotide variant-based genome-wide association studies improving our understanding of the genetics of CAD, the contribution of structural variants (SVs) to the risk of CAD remains largely unclear.

Method And Results: We leveraged SVs detected from high-coverage whole genome sequencing data in a diverse group of participants from the National Heart Lung and Blood Institute's Trans-Omics for Precision Medicine program.

Despite significant advances in its management, AF remains a major healthcare burden affecting millions of individuals. Rhythm control with antiarrhythmic drugs or catheter ablation has been shown to improve symptoms and outcomes in AF patients, but current treatment options have limited efficacy and/or significant side-effects. Novel mechanism-based approaches could potentially be more effective, enabling improved therapeutic strategies for managing AF.

Acute respiratory distress syndrome (ARDS) is a clinical syndrome of acute hypoxic respiratory failure caused by diffuse lung inflammation and edema. ARDS can be precipitated by intrapulmonary factors or extrapulmonary factors, which can lead to severe hypoxemia. Patients suffering from ARDS have high mortality rates, including a 28-day mortality rate of 34.

According to the ESC guidelines, cangrelor may be considered in P2Y12-inhibitor-naïve acute coronary syndrome (ACS) patients undergoing percutaneous coronary intervention (PCI). The aim of this review is to summarize available evidence on the optimal maintenance therapy with P2Y12 receptor inhibitor after cangrelor. Transitioning from cangrelor to a thienopyridine, but not ticagrelor, can be associated with a drug-drug interaction (DDI); therefore, a ticagrelor loading dose (LD) can be given any time before, during, or at the end of a cangrelor infusion, while a LD of clopidogrel or prasugrel should be administered at the time the infusion of cangrelor ends or within 30 minutes before the end of infusion in the case of a LD of prasugrel.

Unlabelled: Neurodegenerative disorders, including Alzheimer's disease and AD-related dementias (AD/ADRD), pose significant challenges to health care systems globally, particularly in Africa. With the advances in medical technology and research capabilities, especially in next-generation sequencing and imaging, vast amounts of data have been generated from AD/ADRD research. Given that the greatest increase in AD/ADRD prevalence is expected to occur in Africa, it is critical to establish comprehensive bioinformatics training programs to help African scientists leverage existing data and collect additional information to untangle AD/ADRD heterogeneity in African populations.

Background: Diagnosing rare genetic disorders relies on precise phenotypic and genotypic analysis, with the Human Phenotype Ontology (HPO) providing a standardized language for capturing clinical phenotypes. Traditional HPO tools, such as Doc2HPO and ClinPhen, employ concept recognition to automate phenotype extraction but struggle with incomplete phenotype assignment, often requiring intensive manual review. While large language models (LLMs) hold promise for more context-driven phenotype extraction, they are prone to errors and "hallucinations," making them less reliable without further refinement.

Anticipating the onset, location and severity of radiation dermatitis before radiotherapy can aid in dermatological care. This study developed a method for creation of a prediction diagram for dermatitis and conducted a comparative verification between the prediction diagram and actual patient condition. The prediction diagram involved converting skin doses into 2 Gy fractionated equivalent doses using α/β of 10.

Introduction: Growing interest centers on the association between circulating ketone bodies (KB) and cognitive function, notably in aging and neurodegenerative diseases.

Methods: Associations of plasma KB with incident dementia and cognitive performances were examined among Multi-Ethnic Study of Atherosclerosis (MESA) participants. KB were measured using plasma samples collected following an overnight fasting at Exam 1 (2000-02) and detailed cognitive testing at Exam 5 (2010-2012,  = 4392), Exam 6 (2016-2018,  = 1838), and in MESA-MIND (2019-2021,  = 2060).

Prolonged antibiotic exposure causes dangerous hematologic side effects, including neutropenia, in up to 34% of patients. Murine studies established a link between the intestinal microbiota and hematopoiesis. To identify factors that predispose to neutropenia in pediatric patients, we evaluated changes in microbiota-derived metabolites and intestinal microbiota composition after prolonged courses of antibiotics.

The concept of love of life, which refers to a positive attitude towards one's own life, care for it and attachment to it, has recently captured the attention of researchers in the field of positive psychology. Despite its growing importance, there is a lack of research investigating the underlying mechanisms through which love of life impacts the flourishing and well-being of individuals. For the first time, the present study examined the mediating roles of optimism and hope in the association between love of life and flourishing in Turkish youth.

Article Synopsis
  • The meta-analysis compares long-term outcomes of transcatheter aortic valve replacement (TAVR) and surgical aortic valve replacement (SAVR) in low-surgical risk patients with severe aortic stenosis.
  • TAVR showed lower all-cause mortality risk within 30 days and up to one year compared to SAVR, but risks were similar after one year.
  • Additionally, TAVR had lower rates of cardiovascular mortality, disabling strokes, rehospitalizations, and new-onset atrial fibrillation, but a higher chance of needing a permanent pacemaker, especially in the first 30 days.

Spreading depolarization (SD) is a slowly propagating wave of massive cellular depolarization that transiently impairs the function of affected brain regions. While SD typically arises as an isolated hemispheric event, we previously reported that reducing M-type potassium current (I) by ablation of in forebrain excitatory neurons results in tightly coupled spontaneous bilateral seizure-SD complexes in the awake mouse cortex. Here we find that enhanced persistent Na current due to gain-of-function (GOF) mutations in (N1768D/+, hereafter D/+) produces a similar compound cortical excitability phenotype.

Background: -mutated acute myeloid leukemia (AML) is the most frequent AML subtype. As wild-type NPM1 is known to orchestrate ribosome biogenesis, it has been hypothesized that altered translation may contribute to leukemogenesis and leukemia maintenance in -mutated AML. However, this hypothesis has never been investigated.

Article Synopsis
  • Mental operations, like evaluating options, require significant attentional effort, and determining the right amount of effort is essential for maximizing rewards without excessive cost.
  • A study involving macaques explored choices and brain activity, linking local reward rates to improved decision-making accuracy and increased attentional effort, as shown by physiological indicators like pupil size.
  • Findings indicated that higher reward rates not only enhanced the clarity of value coding in specific brain regions (ventral striatum and orbitofrontal cortex) but also suggested that attentional effort operates via distinct population codes for value, contributing to the understanding of rational inattention in economic decisions.
