Non-recovery acute kidney injury and additional risk factors for short-term and long-term hypoglycemia: A multi-institutional cohort study.

Background: Acute kidney injury (AKI) is associated with increased in-hospital and short-term hypoglycemia risk. However, the impact of non-recovery of renal function before discharge on hypoglycemia risk in AKI survivors after discharge have not been well studied. We aim to analyze the association between non-recovery of AKI and hypoglycemia, hyperglycemia crisis risk, to identify additional risk factors for hypoglycemia, and to examine the impact of AKI non-recovery on HbA1c variability.

Impact of Different Angiotensin-Converting Enzyme Inhibitors or Angiotensin Receptor Blocker Resumption Timing on Post Acute Kidney Injury Outcomes.

Introduction: Evidence suggests a survival benefit from resuming angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) post acute kidney injury (AKI) compared to nonuse; however, the optimal timing and its impact on outcomes are unclear. The risks of earlier resumption, such as recurrent AKI or hyperkalemia, remain unexplored.

Methods: Using multiinstitutional electronic health records, we analyzed the relationship between 3 ACEI or ARB (ACEI/ARB) resumption timelines post-AKI (prior to discharge, 0-3 months, and 4-6 months postdischarge) and outcomes including all-cause mortality, major adverse cardiac and cerebrovascular events (MACCEs), dialysis initiation or end-stage renal disease (ESRD), severe hyperkalemia, and recurrent AKI with hospitalization.

The role of maintaining lower LDL-C level during statin treatment for advanced CKD patients.

Background And Aims: Different from other high cardiovascular (CV) risks populations, the evidence supporting the CV protective effect of LDL-C reduction with statins in chronic kidney disease (CKD) patients is comparatively scarce. This study is aimed to investigate the role of maintaining lower LDL-C level in advanced CKD patients.

Methods: By using Chang Gung Research Database, on the basis of Taiwan's largest healthcare group, a total of 5367 adult patients newly-diagnosed with stage 4 CKD and receiving statin were extracted and further categorized into three groups based on their LDL-C levels: <70 mg/dL, 70-100 mg/dL, and ≥100 mg/dL.

PPAR-γ agonist pioglitazone and the risks of malignancy among type2 diabetes mellitus patients.

Aims: PPAR-gamma shows promise in inhibiting malignancy cell progression. However, pioglitazone, the sole current PPAR-gamma agonist, was reported to have risks of bladder cancer in previous clinical researches. This study is aimed to assess the influence of pioglitazone on the development of tumors.

Prognostic nutritional index as a predictive marker for acute kidney injury in adult critical illness population: a systematic review and diagnostic test accuracy meta-analysis.

Background: The prognostic nutritional index (PNI), integrating nutrition and inflammation markers, has been increasingly recognized as a prognostic predictor in diverse patient cohorts. Recently, its effectiveness as a predictive marker for acute kidney injury (AKI) in various clinical settings has gained attention. This study aims to assess the predictive accuracy of the PNI for AKI in critically ill populations through systematic review and meta-analysis.

Comparison of different medical treatments for primary hyperaldosteronism: a systematic review and network meta-analysis.

Background: The effectiveness and side effects between different medical treatments in patients with primary hyperaldosteronism have not been systematically studied.

Objective: To analyze the efficacy between different mineralocorticoid receptor antagonists (MRAs) and epithelial sodium channel (ENaC) inhibitors in a network meta-analysis (NMA) framework, while also evaluating adverse events.

Design: Systematic review and NMA.

Fibrate and the risk of cardiovascular disease among moderate chronic kidney disease patients with primary hypertriglyceridemia.

Introduction: Hypertriglyceridemia is the most prevalent dyslipidemia in patients with chronic kidney disease (CKD). However, research about fibrate treatment in CKD patients is limited, and assessing its benefits becomes challenging due to the frequent concurrent use of statins. Thus, this study is aimed to investigate the role of fibrate in CKD stage 3 patients with hypertriglyceridemia who did not receive other lipid-lowering agents.

Exploring nontraditional cardiorenal advantages of SGLT-2 inhibitors and GLP-1 receptor agonists.

This commentary provides an analysis of the study by Fu et al. in Kidney International, which employs 3 administrative databases to investigate the hyperkalemia protective effects of sodium-glucose cotransporter-2 inhibitors, glucagon-like peptide-1 receptor agonists, and dipeptidyl peptidase-4 inhibitors. It emphasizes the methodological approach, notably the use of a fixed-effect model to aggregate pairwise comparisons from 3 data sets.

Phasic dopamine signals are reduced in the spontaneously hypertensive rat and increased by methylphenidate.

The spontaneously hypertensive rat (SHR) is a selectively bred animal strain that is frequently used to model attention-deficit hyperactivity disorder (ADHD) because of certain genetically determined behavioural characteristics. To test the hypothesis that the characteristically altered response to positive reinforcement in SHRs may be due to altered phasic dopamine response to reward, we measured phasic dopamine signals in the SHRs and Sprague Dawley (SD) rats using in vivo fast-scan cyclic voltammetry. The effects of the dopamine reuptake inhibitor, methylphenidate, on these signals were also studied.

All-cause and immune checkpoint inhibitor-associated acute kidney injury in immune checkpoint inhibitor users: a meta-analysis of occurrence rate, risk factors and mortality.

Background: Immune checkpoint inhibitors (ICIs) have been associated with acute kidney injury (AKI). However, the occurrence rate of ICI-related AKI has not been systematically examined. Additionally, exposure to proton pump inhibitors (PPIs) and non-steroidal anti-inflammatory drugs (NSAIDs) were considered as risk factors for AKI, but with inconclusive results in ICI-related AKI.

Clinical outcomes between elderly ESKD patients under peritoneal dialysis and hemodialysis: a national cohort study.

With ageing populations, new elderly end-stage kidney disease (ESKD) cases rise. Unlike younger patients, elderly ESKD patients are less likely to undergo kidney transplant, and therefore the decision of receiving peritoneal dialysis (PD) and hemodialysis (HD) is more crucial. A total of 36,852 patients, aged more than 65, who were newly diagnosed with ESKD and initiated renal replacement therapy between 2013 and 2019 were identified.

Immunosenescence, gut dysbiosis, and chronic kidney disease: Interplay and implications for clinical management.

Immunosenescence refers to the immune system changes observed in individuals over 50 years old, characterized by diminished immune response and chronic inflammation. Recent investigations have highlighted similar immune alterations in patients with reduced kidney function. The immune system and kidney function have been found to be closely interconnected.

Effects of multicomponent exercise training on muscle oxygenation in young and older adults.
