Safety Profile of Biportal Endoscopic Spine Surgery Compared to Conventional Microscopic Approach: A Pooled Analysis of 2 Randomized Controlled Trials.

Objective: To compare the safety profiles of biportal endoscopic spinal surgery (BESS) and microscopic spinal surgery (MSS) for lumbar disc herniation and spinal stenosis by analyzing the associated adverse events.

Methods: We pooled data from 2 prospective randomized controlled trials involving 220 patients (110 in each group) who underwent single-level lumbar surgery. Participants aged 20-80 years with radiating pain due to lumbar disc herniation or spinal stenosis were included in this study.

Steroid sulfatase suppresses keratinization by inducing proteasomal degradation of E-cadherin via Hakai regulation.

X-linked ichthyosis (XLI) is a genetic disorder characterized by a steroid sulfatase (STS) deficiency inducing excessive cholesterol sulfate accumulation and keratinization. Our study utilizes STS knockout mice to reproduce the hyperkeratinization typical of XLI, providing a valuable model for investigating the underlying mechanisms. From the experiment of STS-deficient keratinocytes using the CRISPR/Cas9 system, we observed upregulation of E-cadherin, which is associated with keratinocyte differentiation and stratification.

Gaps and Similarities in Research Use LOINC Codes Utilized in Korean University Hospitals: Towards Semantic Interoperability for Patient Care.

Background: The accuracy of Logical Observation Identifiers Names and Codes (LOINC) mappings is reportedly low, and the LOINC codes used for research purposes in Korea have not been validated for accuracy or usability. Our study aimed to evaluate the discrepancies and similarities in interoperability using existing LOINC mappings in actual patient care settings.

Methods: We collected data on local test codes and their corresponding LOINC mappings from seven university hospitals.

Artemisinin-Quinidine Combination for Suppressing Ventricular Tachyarrhythmia in an Ex Vivo Model of Brugada Syndrome.

Background: The ionic mechanism underlying Brugada syndrome (BrS) arises from an imbalance in transient outward current flow between the epicardium and endocardium. Previous studies report that artemisinin, originally derived from a Chinese herb for antimalarial use, inhibits the Ito current in canines. In a prior study, we showed the antiarrhythmic effects of artemisinin in BrS wedge preparation models.

Uncovering potential causal genes for undiagnosed congenital anomalies using an in-house pipeline for trio-based whole-genome sequencing.

Background: Congenital anomalies (CAs) encompass a wide spectrum of structural and functional abnormalities during fetal development, commonly presenting at birth. Identifying the cause of CA is essential for accurate diagnosis and treatment. Using a target-gene approach, genetic variants could be found in certain CA patients.
