: Although the risk of serious bleeding following peritoneal dialysis catheter insertion is low, pericannular bleeding can increase the risk of catheter-related infections and reduce catheter survival. We aimed to analyze the risk factors for bleeding complications during peritoneal dialysis catheter insertion and assess whether temporary preemptive hemodialysis before catheterization can reduce bleeding and improve catheter survival. : We retrospectively analyzed bleeding complications and catheter survival in patients who underwent temporary hemodialysis prior to peritoneal dialysis catheter insertion.

BACKGROUND Diffusion tensor imaging (DTI) is an advanced magnetic resonance imaging (MRI) method used to identify changes in microstructures in the brain's white matter. Severe brain injuries after trauma are associated with disorders of consciousness (DOC) and may result in hyponatremia due to damage to the hypothalamus. This case-control study aimed to use DTI to evaluate the hypothalamus in 36 patients with hyponatremia and DOC due to severe brain injuries.

Backgruound: Because premed students do not take courses related to medicine during their first 2 years, they cannot establish their identity as students at medical schools, making it difficult for them to set goals as future doctors. We conducted an early clinical and basic laboratory exposure program for premed students and studied the effects of the program and student satisfaction levels.

Methods: We performed an early clinical and basic laboratory exposure program for premed students for 2 days and evaluated the effects of the program and student satisfaction with it.

Background: In case of intractable exit site and/or tunnel infections, peritoneal dialysis (PD) catheter removal and re-insertion are recommended. Previous studies have reported the possibility of catheter salvage before removal, but they were either case-series or had a small sample size.

Methods: We identified all incident patients with PD who underwent revision at a tertiary medical center.

Anatomical differences between the renal cortex and medulla may influence inflammatory responses. Owing to the difficulty in diagnosing rejections from the medulla, rejection is usually diagnosed through the cortex. However, previous studies have shown that there are no significant differences in renal cortical and medullary lesions in acute allograft rejection.

Background: A population-based study would be useful to identify the association between chronic kidney disease (CKD) or acute kidney injury (AKI) and prognosis of coronavirus disease 2019 (COVID-19) patients.

Methods: This retrospective study utilized the claim data from Korea. Patients who underwent COVID-19 testing and were confirmed to be positive were included and divided into the following three groups based on the presence of CKD or requirement of maintenance dialysis: Non-CKD (participants without CKD), non-dialysis CKD (ND-CKD), and dialysis-dependent CKD (DD-CKD) patients.

Aim: Previous studies have reported inconsistent results regarding the association between metformin use and clinical outcomes in diabetes mellitus (DM) patients with coronavirus disease 2019 (COVID-19). This study aimed to evaluate the association between metformin use and clinical outcomes in DM patients with COVID-19.

Methods: This retrospective study was based on claims data.

Background: We investigated the effects of tranilast on epithelial-to-mesenchymal transition (EMT) in an animal model and on the EMT signaling pathway in human peritoneal mesothelial cells (HPMCs).

Methods: We performed studies (cytotoxicity, cell morphology, and western blot analyses) on HPMCs from human omenta, along with studies (peritoneal membrane function and morphometric and immunohistochemical analyses) on Sprague Dawley rats. Thirty-two rats were divided into three groups: control (C) group (peritoneal dialysis [PD] catheter but not infused with dialysate), PD group (4.

Background: Fahr's syndrome presenting multiple and symmetric calcification of basal ganglia and cerebral cortex is rare, and idiopathic hypoparatyroidism is known as one of the causes. The relationship between ossification of posterior longitudinal ligament (OPLL) and idiopathic hypoparatyroidism is also reported in a few cases. Here, we report a patient presenting concomitant Fahr's syndrome and thoracic OPLL developed by idiopathic hypoparatyroidism.

Background: Periodontitis and cardiovascular disease (CVD) share inflammation as common pathogenesis. Evaluating the association between periodontitis and CVD would be helpful to better understand the pathophysiology and various complications of periodontitis. We aimed to determine whether there is an independent relationship between periodontitis and various CVD risk indicators or prevalence.

Non-alcoholic fatty liver disease (NAFLD) is associated with the dysregulation of multiple metabolic and inflammatory pathways. These can lead to extrahepatic disorders involving the kidney, a vulnerable organ responsible for extra-renal complications. Evaluating the association between NAFLD and low-grade albuminuria as a renal complication would be helpful to better understand the pathophysiology and extra-hepatic complications of NAFLD.

Clusterin is a secretory glycoprotein that is involved in multiple physiopathological processes, including lipid metabolism. Previous studies have shown that clusterin prevents hepatic lipid accumulation via suppression of sterol regulatory element-binding protein (SREBP) 1. In this study, we examined the role of clusterin in renal lipid accumulation in clusterin-knockout mice and NRK52e tubular epithelial cells.
