Environment-wide association study of five per- and polyfluoroalkyl substance (PFASs) exposure pathways in Korean adolescents from the Korean National Environmental Health Survey (2018-2020).

Per- and polyfluoroalkyl substances (PFASs) are widely used in consumer products and are easily encountered in daily life. PFASs that accumulate in the human body can negatively affect adolescent health. This study aimed to identify key exposure pathways that influence serum PFAS levels in Korean adolescents, using data from the Korean National Environmental Health Survey (2018-2020) cycle 4.

Role of 11β-hydroxysteroid dehydrogenase type 1 inhibition in the antiobesity effect of J2H-1702 on adipocytes and a high-fat diet-induced NASH model.

Obesity due to excessive body fat accumulation remains a global problem. Patients with obesity have high cortisol levels, and its dysregulation is caused by increased 11β-hydroxysteroid dehydrogenase type 1 (11β-HSD1) levels. The effects and mechanism of J2H-1702, an 11β-HSD1 inhibitor, on nonalcoholic steatohepatitis (NASH) were explored.

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.

Identification and Characterization of Vancomycin-Resistant Staphylococcus aureus CC45/USA600, North Carolina, USA, 2021.

Vancomycin-resistant Staphylococcus aureus (VRSA) is a rare but serious public health concern. We describe a VRSA case in North Carolina, USA. The isolate from the case belonged to the USA600 lineage and clonal complex 45.
