Aim: Recent reports suggest that immediate-start peritoneal dialysis (ISPD) initiated immediately after catheter insertion demonstrates better long-term outcomes. However, the survival rate of ISPD versus haemodialysis (HD) remains uncertain. This study aimed to compare survival rates between ISPD and HD using a matched-pair cohort.

The peptidyl-prolyl isomerase (PIN1) plays a vital role in cellular processes, including intracellular signaling and apoptosis. While oxidative stress is considered one of the primary mechanisms of pathogenesis in brain ischemic injury, the precise function of PIN1 in this disease remains to be elucidated. We constructed a cell-permeable PEP-1-PIN1 fusion protein and investigated PIN1's function in HT-22 hippocampal cells as well as in a brain ischemic injury gerbil model.

  • The study aimed to assess how effective and safe add-on dapagliflozin is for type 2 diabetes patients who weren't properly managing their blood sugar levels with metformin and linagliptin.
  • In a trial with 235 patients, half received a fixed-dose combination of dapagliflozin and linagliptin, while the other half received linagliptin plus a placebo, with results measured after 24 weeks.
  • The dapagliflozin group showed significantly lower HbA1c levels and better outcomes in achieving target blood sugar levels compared to the placebo group, with a low risk of adverse effects being noted for both treatments.

Low muscle mass is a risk factor for mortality in patients with chronic kidney disease (CKD). However, it is not clear to what extent low muscle mass contributes to this risk, either independently or in combination with metabolic abnormalities and frailty. This study used data from the National Health and Nutrition Examination Survey 1999-2006 and 2011-2018.

Article Synopsis
  • Interest in citrate-based dialysate (Cit-D) is increasing due to its advantages in anticoagulation and dialysis efficiency, yet research on its use in high-volume hemodiafiltration (HDF) is limited.
  • This study analyzed 28 patients who switched from acetate-based dialysate (Acet-D) to Cit-D, examining safety and effectiveness across three 12-week periods.
  • Results showed a 17% reduction in heparin dosage, improvements in dialysis efficiency (increased Kt/V and urea reduction ratio), and no significant safety concerns, suggesting Cit-D may have benefits over Acet-D in this setting.

Background: Pre-transplant donor-specific anti-human leukocyte antigen antibody (HLA-DSA) is a recognized risk factor for acute antibody-mediated rejection (ABMR) and allograft failure. However, the clinical relevance of pre-transplant crossmatch (XM)-negative HLA-DSA remains unclear.

Methods: We investigated the effect of XM-negative HLA-DSA on post-transplant clinical outcomes using data from the Korean Organ Transplantation Registry (KOTRY).

This study developed and assessed the impact of a digitally enabled self-care intervention program tailored for older adults with type 2 diabetes led by nursing professionals. A randomized controlled trial of a 12-week digital self-care intervention was conducted with 105 older Korean adults with type 2 diabetes. The intervention involved self-recording in the DiaNote application, newly developed for the study and a phone visit.

Objective: Since the establishment of Regional Trauma Centers (RTCs) in Korea, significant efforts have been made to improve the quality of care for patients with trauma. Simultaneously, the Department of Neurosurgery assigned neurotrauma specialists to RTCs to provide specialized care to patients with traumatic brain injury (TBI). In this study, we sought to determine whether neurotrauma specialists, compared to general neurosurgeons, could make a significant difference in treatment outcomes of patients with TBI.

Background: Autonomic dysfunction as a long-term complication may occur in end-stage kidney disease (ESKD) patients and can be diagnosed using heart rate variability (HRV) analyzed from electrocardiogram (ECG) recordings. There is limited data about HRV using real-time ECG to predict hemodialysis (HD) efficiency in patients with ESKD who are routinely doing HD in the real world.

Methods: A total of 50 patients (62.

Aim: To investigate the efficacy and safety of pioglitazone compared to placebo when added to metformin plus dapagliflozin, a sodium-glucose cotransporter-2 (SGLT2) inhibitor, for patients with type 2 diabetes mellitus (T2DM).

Materials And Methods: In a multicentre study, with a randomized, double-blind, placebo-controlled design, 249 Korean patients with T2DM suboptimally managed on metformin and dapagliflozin were assigned to receive either pioglitazone (15 mg daily) or placebo for 24 weeks, followed by a 24-week pioglitazone extension. Primary outcomes included changes in glycated haemoglobin (HbA1c), with secondary outcomes assessing insulin resistance, adiponectin levels, lipid profiles, liver enzymes, body weight and waist circumference.

Background: Immediate-start peritoneal dialysis (ISPD) is an effective renal replacement therapy that can prevent central venous catheterization due to its immediate initiation of peritoneal dialysis (PD) after catheter insertion without a break-in period. This study aimed to investigate the effect of ISPD on long-term patient survival.

Methods: In this retrospective single-center cohort study, 178 consecutive patients who started PD from August 2005 to March 2023 were enrolled, from whom 144 patients with ISPD were analyzed.

  • Autonomic neuropathy, a common complication of diabetes mellitus (DM), can be assessed through heart rate variability (HRV) using electrocardiograms (ECG), but there is limited research on real-time HRV and glucose monitoring in DM patients.
  • The study involved 43 DM patients who underwent continuous ECG and glucose monitoring to analyze the relationship between HRV and glucose levels.
  • Results showed that lower HRV was significantly associated with poorly controlled glucose levels, indicating that high blood sugar may lead to cardiac autonomic dysfunction in these patients.

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.
