Its biomarkers and molecular characteristics remain controversial, and there are no specific therapeutic targets or strategies for its clinical treatment.

Methods: A retrospective study was conducted between January 2010 and December 2021.

Pressure induces peritoneal fibrosis and inflammation through CD44 signaling.

Peritoneal dialysis (PD) is a widely used sustainable kidney replacement therapy. Prolonged use of PD fluids is associated with mesothelial-mesenchymal transition, peritoneal fibrosis, and eventual ultrafiltration (UF) failure. However, the impact of pressure on the peritoneum remains unclear.

Urban-rural health disparity among patients with chronic kidney disease: a cross-sectional community-based study from 2012 to 2019.

Objectives: The incidence of chronic kidney disease (CKD) is increasing owing to the ageing population, resulting in an increased demand for dialysis and kidney transplantation, which can be costly. Current research lacks clarity regarding the relationship between residence setting and CKD prevalence or its related risk factors. This study explored the urban-rural disparities in CKD prevalence and risk factors in Taiwan.

Risk factors for acute kidney injury or mortality and long-term follow-up in coronavirus disease 2019 infected patients in the era before vaccination.

Background: Acute kidney injury (AKI) is a severe complication of coronavirus disease 2019 (COVID-19) and is associated with a higher risk of mortality. Understanding the risk factors contributing to COVID-19-related AKI and mortality before vaccination is important for the initiation of preventative measures and early treatment strategies.

Methods: This study included patients aged ≥18 years diagnosed with COVID-19 through polymerase chain reaction from May 2020 to July 2021, admitted in three local hospitals in Taiwan, with an extended follow-up until June 30, 2022.

Epigallocatechin Gallate Derivative Y6 Reverses Oxaliplatin Resistance in Hepatocellular Carcinoma via Targeting the MiR-338-3p/HIF-1α/TWIST Axis to Inhibit EMT.

Background: The emergence of drug resistance to oxaliplatin (OXA) is one of the critical obstacles in the therapy of advanced Hepatocellular Carcinoma (HCC). As an ethyl derivative of the natural compound epigallocatechin gallate (epigallocatechin-3-gallate, EGCG), Y6 was found to be able to enhance the sensitivity of HCC cells to doxorubicin. This study aimed to investigate the effect of Y6 on oxaliplatin resistance in HCC.

Prevention and management of cytomegalovirus infection and disease in kidney transplant: A consensus statement of the Transplantation Society of Taiwan.

Kidney transplant recipients have an increased risk of cytomegalovirus (CMV) infection and disease. A strategy for mitigating the risk of CMV infection in kidney transplant recipients has not yet been established in Taiwan. The Transplantation Society of Taiwan aimed to develop a consensus by expert opinion on the prevention and management of CMV infection.

Interprofessional Differences in Multidimensional Self-Efficacy Associated With Professional Performance in Nephrology During Case-Based Learning.

Introduction: Postgraduate medical education assumes rising importance in the rapidly advancing field of medicine. Case-based learning (CBL), a learner-centered pedagogy employing clinical cases to improve decision-making, is widely embraced in postgraduate medical education, including nephrology. Studies suggest that learning self-efficacy (SE) was closely associated with learning motivation and academic performance; however, very few studies examined this association in postgraduate nephrology education.

MicroRNA-34 Family in Cancers: Role, Mechanism, and Therapeutic Potential.

MicroRNA (miRNA) are small noncoding RNAs that play vital roles in post-transcriptional gene regulation by inhibiting mRNA translation or promoting mRNA degradation. The dysregulation of miRNA has been implicated in numerous human diseases, including cancers. miR-34 family members (miR-34s), including miR-34a, miR-34b, and miR-34c, have emerged as the most extensively studied tumor-suppressive miRNAs.

Weak synchronization can alter circadian period length: implications for aging and disease conditions.

The synchronization of multiple oscillators serves as the central mechanism for maintaining stable circadian rhythms in physiology and behavior. Aging and disease can disrupt synchronization, leading to changes in the periodicity of circadian activities. While our understanding of the circadian clock under synchronization has advanced significantly, less is known about its behavior outside synchronization, which can also fall within a predictable domain.

A National Case-Crossover Study on the Risk of Kidney Injury Requiring Dialysis after Sepsis.

Background: Patients with sepsis-associated acute kidney injury (AKI) are at risk of kidney damage, potentially necessitating acute temporary or chronic dialysis. Our study aims to estimate the odds ratio (OR) of preceding sepsis among patients requiring their first dialysis.

Methods: A nationwide population-based case-only study was conducted using claims records from the National Health insurance database of Taiwan.

Leukocyte 8-hydroxy-2'-deoxyguanosine as an oxidative stress marker to predict cardiovascular events and death in chronic hemodialysis patients.

Background: Hemodialysis patients have a markedly increased risk of cardiovascular (CV) morbidity and mortality. Oxidative stress plays a pathogenic role in the progression of atherosclerosis and CV disease among chronic hemodialysis patients. The 8-hydroxy-2'-deoxyguanosine (8-OHdG) content in leukocyte deoxyribonucleic acid (DNA) has been shown as a sensitive and well-known biomarker of oxidant-induced DNA damage in chronic hemodialysis patients.

Transitions of dialysis status and outcomes after the unplanned first dialysis: a nationwide population-based cohort study.

In Taiwan, most first-time dialysis was started without the creation of an arteriovenous shunt. Here, we aimed to elucidate the transitions of dialysis status in the unplanned first dialysis patients and determine factors associated with their outcomes. A total of 50,315 unplanned first dialysis patients aged more than 18 years were identified from the National Health Insurance Dataset in Taiwan between 2001 and 2012.

Prevention and management of tuberculosis in solid organ transplantation: A consensus statement of the transplantation society of Taiwan.

Solid organ transplant recipients have an increased risk of tuberculosis (TB). Due to the use of immunosuppressants, the incidence of TB among solid organ transplant recipients has been consistently reported to be higher than that among the general population. TB frequently develops within the first year after transplantation when a high level of immunosuppression is maintained.

Genetic insight into primary glomerulonephritis.

Primary glomerulonephritis is a major global health concern and a disorder with significant heritable components. Rapid advances in sequencing technologies have led to genome-wide, high-throughput investigations of the genetic basis of complex human traits. Genetic studies have successfully mapped several susceptibility loci and disease-causing genes for different subtypes of primary glomerulonephritis.

The Incidence of Contrast-Induced Nephropathy and the Need of Dialysis in Patients Receiving Angiography: A Systematic Review and Meta-Analysis.

The purpose of this phase I clinical trial is to assess the safety and tolerability of allogeneic adipose tissue-derived stem cells (ADSCs) among chronic kidney disease (CKD) patients. 12 eligible CKD patients with an estimated glomerular filtration rate (eGFR) of 15-44 ml/min/1.73 m received one dose of intravenous allogeneic ADSCs (ELIXCYTE ), as 3 groups: 3 low dose (6.

Efficacy of Osteoporosis Medications for Patients With Chronic Kidney Disease: An Updated Systematic Review and Network Meta-Analysis.

Chronic kidney disease (CKD) is associated with bone and mineral metabolism. In this study we evaluated the comparative efficacies and safety of osteoporosis medications in patients with CKD or a history of kidney transplantation, and make recommendations for the best choice of osteoporosis treatment among patients with CKD or a history of kidney transplantation. We systemically searched for randomized controlled trials published in PubMed, Embase, and Cochrane databases up to June 2020.

The Influence of Diabetes Mellitus on the Risks of End-Stage Kidney Disease and Mortality After Liver Transplantation.

This retrospective study aimed to investigate the effect of diabetes mellitus (DM) on the risks of end-stage kidney disease (ESKD) and post-liver transplantation (post-LT) mortality. Using data from the National Health Insurance Research Database, Taiwan, 3,489 patients who received a LT between 1 January 2005, and 31 December 2015, were enrolled in this study and divided into the pre-existing DM, post-LT DM (PLTDM), and without DM groups. All subjects were followed up from 1 year after LT to the index date for ESKD, and the occurrence of death, or until 31 December 2016.

Predicting 3-month and 1-year mortality for patients initiating dialysis: a population-based cohort study.

Background: Despite the continual improvements in dialysis treatments, mortality in end-stage kidney disease (ESKD) remains high. Many mortality prediction models are available, but most of them are not precise enough to be used in the clinical practice. We aimed to develop and validate two prediction models for 3-month and 1-year patient mortality after dialysis initiation in our population.

Differentiation of fetal hematopoietic stem cells requires ARID4B to restrict autocrine KITLG/KIT-Src signaling.

Balance between the hematopoietic stem cell (HSC) duality to either possess self-renewal capacity or differentiate into multipotency progenitors (MPPs) is crucial for maintaining homeostasis of the hematopoietic stem/progenitor cell (HSPC) compartment. To retain the HSC self-renewal activity, KIT, a receptor tyrosine kinase, in HSCs is activated by its cognate ligand KITLG originating from niche cells. Here, we show that AT-rich interaction domain 4B (ARID4B) interferes with KITLG/KIT signaling, consequently allowing HSC differentiation.
