Association of rapid response system with clinical outcomes after surgery under general anesthesia.

Background: In this population-based cohort study involving a nationwide database from South Korea, we aimed to determine whether rapid response system (RRS) implementation is associated with mortality and morbidity after surgery under general anesthesia.

Methods: Patients who underwent surgery under general anesthesia at the hospital between January 1, 2021, and December 31, 2021. Patients admitted to hospitals with an RRS were categorized into the RRS group, whereas those without an RRS were categorized into the non-RRS group.

Post-transplant cyclophosphamide plus anti-thymocyte globulin decreased serum IL-6 levels when compared with post-transplant cyclophosphamide alone after haploidentical hematopoietic stem cell transplantation.

Background: Post-transplantation cyclophosphamide (PTCy) and anti-thymocyte globulin (ATG) are common prophylactic strategies for graft-versus-host disease (GVHD) after haploidentical hematopoietic stem cell transplantation (haplo-HSCT). Interleukin (IL)-6 is a surrogate marker for cytokine release syndrome (CRS) and acute GVHD.

Method: The clinical outcomes and complications of haplo-HSCT with PTCy plus ATG versus PTCy monotherapy were compared according to serum IL-6 levels at Chungnam National University Hospital (Daejeon, South Korea) from January 2019 to February 2023.

Analyzing collaborations in clinical trials in Korea using association rule mining.

Identifying how trial sites collaborate is essential for multicenter trials. The ways in which collaboration among trial sites is established can vary according to study phase and clinical trial domains. In this study, we employed association rule mining to reveal trial collaboration.

Research on unintroduced new drugs in South Korea from 2011 to 2020: approaches to prioritization and strategy.

In recent years, with the experience of the COVID-19 pandemic, countries around the world have realized that improving patient access to new medicines can have a significant impact on public health and economic stability. The aim of this study was to identify new drugs that are urgently needed among those not yet available in South Korea from 2011 to 2020, and to develop strategies to improve access by analyzing the causes of delay. Through a 3-step screening process that included a literature review of new drugs, surveys of domestic clinicians and academics, and consideration of expedited review status by regulatory authorities, 34 out of 244 unreleased new drugs were prioritized for rapid introduction.

Identification of a Subpopulation of Astrocyte Progenitor Cells in the Neonatal Subventricular Zone: Evidence that Migration is Regulated by Glutamate Signaling.

In mice engineered to express enhanced green fluorescent protein (eGFP) under the control of the entire glutamate transporter 1 (GLT1) gene, eGFP is found in all 'adult' cortical astrocytes. However, when 8.3 kilobases of the human GLT1/EAAT2 promoter is used to control expression of tdTomato (tdT), tdT is only found in a subpopulation of these eGFP-expressing astrocytes.
