We sought to identify plasma biomarkers predictive of MAKE in patients hospitalized with COVID-19. STUDY DESIGN: Prospective cohort study. SETTING AND PARTICIPANTS: A total of 576 patients hospitalized with COVID-19 between March 2020 and January 2021 across 3 academic medical centers.

RATIONALE AND OBJECTIVE: Hypertension is a known risk factor for dementia and cognitive impairment. There are limited data on the relation of systolic blood pressure (SBP) and diastolic blood pressure (DBP) with incident cognitive impairment in adults with chronic kidney disease. We sought to identify and characterize the relationship among blood pressure, cognitive impairment, and severity of decreased kidney function in adults with chronic kidney disease. STUDY DESIGN: Longitudinal Cohort study...

Fatigue surrounding hemodialysis treatments is a common and often debilitating symptom that impacts patients' quality of life. Intra-dialytic fatigue develops or worsens immediately prior to hemodialysis and persists through the dialysis treatment. Little is known about associated risk factors or pathophysiology, although it may relate to a classical conditioning response. Post-dialysis fatigue (PDF) develops or worsens after hemodialysis and may persist for hours. There is no consensus on how to measure PDF...

Recent advances in multiparametric Magnetic Resonance Imaging (MRI) allow multiple quantitative measures to assess kidney morphology, tissue microstructure, oxygenation, kidney blood flow and perfusion to be collected in a single scan session. Animal and clinical studies have investigated the relationship between the different MRI measures and biological processes, although their interpretation can be complex due to variations in study design and generally small participant numbers. However, emerging themes include the apparent diffusion coefficient (ADC) derived from diffusion weighted imaging, T1 and T2 mapping parameters and cortical perfusion being consistently associated with kidney damage and predicting kidney function decline...

RATIONALE & OBJECTIVE: Hypokalemia may accelerate kidney function decline. Both hypo- and hyperkalemia can cause sudden cardiac death. However, little is known about the relationship between serum potassium and death or the occurrence of kidney failure requiring replacement therapy (KRT). We investigated this relationship in older people with chronic kidney disease (CKD) stage 4-5. STUDY DESIGN: Prospective observational cohort study. SETTING & PARTICIPANTS: We followed 1714 patients (≥65y) from the European QUALity (EQUAL) study for eight years from their first eGFR <20ml/min/1...

RATIONALE & OBJECTIVE: Central venous catheters (CVCs) are widely used for hemodialysis but are prone to burdensome and costly bloodstream infections. We aimed to determine whether multifaceted quality improvement interventions in hemodialysis units can prevent hemodialysis catheter-related bloodstream infections (HDCRBSI). STUDY DESIGN: Systematic review. SETTING & STUDY POPULATIONS: People receiving hemodialysis via a CVC outside of intensive care units (ICU)...

RATIONALE & OBJECTIVE: The clinical implications of the discrepancy between cystatin C (cysC)- and serum creatinine (sCr)-estimated glomerular filtration rate (eGFR) in patients with heart failure and reduced ejection fraction (HFrEF) are unknown. STUDY DESIGN: Post-hoc analysis of randomized trial data. SETTING & PARTICIPANTS: 1,970 patients with HFrEF enrolled in PARADIGM-HF with available baseline cysC and sCr. EXPOSURE: Intra-individual differences between eGFRcysC and eGFRsCr (eGFRdiffcysC-sCr )...

RATIONALE & OBJECTIVE: Obesity is common among patients with end-stage kidney disease (ESKD) and is a pervasive barrier to kidney transplantation. Patient perspectives about barriers to weight loss and patient and health care professionals' viewpoints about optimal obesity management in ESKD are needed. STUDY DESIGN: Qualitative study using a descriptive phenomenological approach to understand ESKD patients' lived experiences with obesity and weight loss and patients' and health professionals' perceptions about optimal obesity care for ESKD patients...

RATIONALE & OBJECTIVE: Acute kidney injury (AKI) carries high rates of morbidity and mortality. This study quantified various short- and long-term outcomes after hospitalization with AKI. STUDY DESIGN: Retrospective propensity score (PS)-matched cohort study. SETTING & PARTICIPANTS: Optum Clinformatics, a national claims database, was used to identify patients hospitalized with and without an AKI discharge diagnosis between January 2007 and September 2020...

RATIONALE & OBJECTIVE: C3 glomerulopathy (C3G) and atypical hemolytic uremic syndrome (aHUS) are two distinct rare kidney diseases caused by dysregulation of the alternative complement pathway. Patients with C3G and concurrent kidney lesions of thrombotic microangiopathy (TMA) have been rarely reported. The objectives of this study were to characterize the clinical features and underlying immunological abnormalities in these patients. STUDY DESIGN: Case series...

RATIONALE & OBJECTIVE: Direct-acting antiviral (DAA) treatment of hepatitis C virus (HCV) infection in patients with chronic kidney disease (CKD) has made transplantation of kidneys from HCV-infected donors to uninfected recipients (D+/R-) feasible. To facilitate an update to the 2018 KDIGO guideline for patients with CKD and HCV, we conducted a systematic review of HCV D+/R- kidney transplantation coupled with DAA treatment. STUDY DESIGN: Systematic review and meta-analysis...

RATIONALE & OBJECTIVE: Acute kidney injury (AKI) is a heterogeneous clinical syndrome with varying causes, pathophysiology, and outcomes. We incorporated plasma and urine biomarker measurements to identify AKI subgroups (subphenotypes) more tightly linked to underlying pathophysiology and long-term clinical outcomes. STUDY DESIGN: Multicenter cohort study. SETTING & PARTICIPANTS: 769 hospitalized adults with AKI matched with 769 without AKI, enrolled from December 2009 to February 2015 in the ASSESS-AKI Study...

RATIONALE & OBJECTIVE: Ultraprocessed foods are widely consumed in the US and are associated with cardiovascular disease (CVD), mortality, and kidney function decline in the general population. We investigated associations between ultraprocessed food intake and chronic kidney disease (CKD) progression, all-cause mortality, and incident CVD in adults with CKD. STUDY DESIGN: Prospective cohort study. SETTING & PARTICIPANTS: Chronic Renal Insufficiency Cohort (CRIC) Study participants who completed baseline dietary questionnaires...

Decisions around initiating and forgoing treatments for kidney failure are complex and contemporary approaches to medical decision-making are designed to uphold patients' own preferences and values when there are multiple clinically reasonable treatment options. When patients do not have cognitive capacity to make their own decisions, these models can be adapted to support previously-expressed preferences of older adults and to promote open futures as autonomous persons for young children. Nonetheless, an autonomy-focused approach to decision-making may not align with other overlapping values and needs of these groups...
