In contrast to most hematopoietic lineages, megakaryocytes (MKs) can derive rapidly and directly from hematopoietic stem cells (HSCs). The underlying mechanism is unclear, however. Here, we show that DNA damage induces MK markers in HSCs and that G2 arrest, an integral part of the DNA damage response, suffices for MK priming followed by irreversible MK differentiation in HSCs, but not in progenitors.

Introduction: Studies exploring the effectiveness and safety of left atrial appendage occlusion (LAAO) in patients with chronic kidney disease (CKD) are limited.

Methods: We utilized the National Inpatient Sample (NIS) to identify hospitalizations for LAAO from 2016 to 2020 and further identified cases with concomitant CKD. The primary outcome was mortality, and secondary outcomes were cerebrovascular accidents, major bleeding, vasopressor requirements, percutaneous coronary intervention, cardiac arrest, acute respiratory failure, transfusion, length of stay (LOS), and total hospital charges.

Changes in ventricular size, related to brain edema and hydrocephalus, as well as the extent of hemorrhage are associated with adverse outcomes in patients with subarachnoid hemorrhage (SAH). Frequently, these are measured manually using consecutive non-contrast computed tomography scans. Here, we developed a rule-based approach which incorporates both intensity and spatial normalization and utilizes user-defined thresholds and anatomical templates to segment both lateral ventricle (LV) and SAH blood volumes automatically from CT images.

Article Synopsis
  • Mammalian AIM-2-like receptor (ALR) proteins are critical for the immune response, as they bind to nucleic acids and trigger the production of interferons or inflammasomes.
  • The ALR gene region in mice is highly variable and undergoes rapid evolution, with the IFI207 gene emerging through gene conversion or recombination events and varying significantly among species.
  • IFI207 enhances the immune response against murine leukemia virus infection and stabilizes STING protein, illustrating the ongoing evolution between hosts and pathogens, which leads to new gene functions that play vital roles in immunity.

infection (CDI) is an intestinal infection that causes morbidity and mortality and places significant burden and cost on the healthcare system, especially in recurrent cases. Antibiotic overuse is well recognized as the leading cause of CDI in high-risk patients, and studies have demonstrated that even short-term antibiotic exposure can cause a large and persistent disturbance to human colonic microbiota. The recovery and sustainability of the gut microbiome after dysbiosis have been associated with fewer CDI recurrences.

We call for a reevaluation of the long-standing dogmatic nutritional principle that "all foods fit" for all cases of eating disorders (EDs) and its corollary, "there are no bad foods" (for anyone ever) during ED treatment. Based on accumulated scientific research, we challenge these ideologies as outdated, confusing, and potentially harmful to many patients. We review the evidence that indicates the folly of these assumptions and show there are a variety of exceptions to these rules, including (1) food allergies, sensitivities, and intolerances, (2) religious and spiritual preferences or doctrines, and (3) the ubiquitous emergence and widespread availability of ultra-processed foods leading to the potential development of addiction-like eating and a higher prevalence of various medical and psychiatric comorbidities, as well as higher mortality.
