Global filtration rate

BACKGROUND: Recently, the target systolic blood pressure (BP) <120 mm Hg was suggested in the population with chronic kidney disease. We aimed to determine the applicability of intensified BP and to assess the incidence of cardiovascular disease (CVD) in the population with chronic kidney disease. METHODS AND RESULTS: Participants who were >20 years old and had estimated glomerular filtration rate 15 to 60 mL/min per 1.73 m2 during 2009 to 2011 were included from the database of Korean National Health Insurance Service and were followed up to 2018...

BACKGROUND & AIMS: Cardiogenic shock (CS) is a serious complication of acute myocardial infarction (MI) and is associated with significant mortality. We describe a contemporary, real-world cohort of patients with ST-elevation MI (STEMI) and CS, including 30-day mortality and clinically relevant predictors of mortality. METHODS: All patients presenting with STEMI who were treated with percutaneous coronary intervention (PCI) in New Zealand (2016 to 2020) were identified from the Aotearoa New Zealand All Cardiology Services Quality Improvement (ANZACS-QI) registry and stratified based on their Killip class on arrival to the cardiac catheterisation laboratory...

IMPORTANCE: Patients with chronic kidney disease (CKD) are at high risk for cardiovascular disease, but their systematic underrepresentation in cardiovascular randomized clinical trials (RCTs) limits the generation of appropriate evidence to guide cardiovascular risk management (CVRM). OBJECTIVE: To evaluate the underrepresentation of patients with CKD in cardiovascular RCTs, and to highlight evidence gaps in CVRM medications in this population. EVIDENCE REVIEW: A systematic search was conducted in ClinicalTrials...

Immunoglobulin A nephropathy (IgAN) is the most common primary glomerular disease, and the "four-hit" theory represents its currently accepted pathogenic mechanism. Mucosal immunity triggered by infections in the respiratory tract, intestines, or other areas leads to antigen presentation, T cell stimulation, B cell maturation, and the production of IgA-producing plasma cells. The proteins B-lymphocyte stimulator (BLyS) and a proliferation-inducing ligand (APRIL) are involved in this process, and alternative complement and lectin pathway activation are also part of the pathogenic mechanism...

BACKGROUND: Atrial fibrillation (AF) has been linked to an increased risk of cardiovascular death, overall mortality and heart failure in patients with type 2 diabetes mellitus (T2DM). The present study investigated the additive effects of paroxysmal AF on left ventricular (LV) function and deformation in T2DM patients with or without AF using the cardiovascular magnetic resonance feature tracking (CMR-FT) technique. METHODS: The present study encompassed 225 T2DM patients differentiated by the presence or absence of paroxysmal AF [T2DM(AF+) and T2DM(AF-), respectively], along with 75 age and sex matched controls, all of whom underwent CMR examination...

IMPORTANCE: There is increasing concern that continued use of a glomerular filtration rate (GFR) estimating equation adjusted for a single racial group could exacerbate chronic kidney disease-related disparities and inequalities. OBJECTIVE: To assess the performance of GFR estimating equations across varied patient populations. DATA SOURCES: PubMed, Embase, Web of Science, ClinicalTrials.gov, and Scopus databases were systematically searched from January 2012 to February 2023...

INTRODUCTION: IgA nephropathy (IgAN) is the most prevalent primary glomerulonephritis globally. While nephrotic syndrome (NS) is uncommon in IgAN, its significance remains unclear. METHODS: We conducted a retrospective analysis of 170 IgAN patients, classifying them into NS ( n = 85) and non-NS ( n = 5) groups. Our study aims to compare their clinical characteristics, treatment responses, and prognoses. Patients were selected based on renal biopsy from 2003 to 2020...

BACKGROUND: Tolvaptan, the only pharmaceutical treatment available for autosomal dominant polycystic kidney disease (ADPKD), reduced the rates of total kidney volume (TKV) increase and kidney function decline in patients with ADPKD in the global phase 3 TEMPO 3:4 study. Since tolvaptan initiation is associated with an initial decline in the estimated glomerular filtration rate (eGFR), this post hoc analysis of the TEMPO 3:4 study investigated whether initial changes in eGFR from baseline to week 3 after tolvaptan administration can predict its longer-term effects on eGFR and TKV in patients with ADPKD...

Chronic kidney disease (CKD) poses a substantial global health burden. It is classified according to estimated glomerular filtration rate (eGFR) (G1-G5) and albuminuria (A1-A3). In recent years the clinicians' therapeutic options for slowing CKD progression and mitigating cardiovascular disease has been significantly expanded:For CKD with albuminuria, concomitant cardiovascular disease or diabetes mellitus, a target blood pressure <130/80mmHg should be aspired. Apart from the geriatric population and those with a life expectancy below one year a blood pressure <140/90mmHg should be targeted...

Fabry disease (FD) is a multisystem lysosomal storage disorder induced by genetic variants in the alpha-galactosidase A ( α GalA) gene. Some FD patients have GLA variants with a reduction in overall α GalA enzymatic activity due to mutated proteins with reduced stability, caused by protein misfolding and premature degradation, but the α GalA catalytic activity remains conserved ("amenable" genetic variants). To correct this misfolding and to prevent premature degradation, migalastat, a small iminosugar molecule was developed...

INTRODUCTION: Population pharmacokinetic studies of β-lactam antimicrobials in critically ill patients derive models that inform their dosing. In non-linear mixed-effects modelling, covariates are often used to improve model fit and explain variability. We aimed to investigate which covariates are most commonly assessed and which are found to be significant, along with global patterns of publication. METHODS: We conducted a systematic review, searching MEDLINE, Embase, CENTRAL and Web of Science on 01 March 2023, including studies of critically ill adults receiving β-lactam antimicrobials who underwent blood sampling for population pharmacokinetic studies...

AIMS: There are minimal data on the prognostic impact of right atrial strain during the reservoir phase (RASr) in patients with immunoglobulin light-chain (AL) cardiac amyloidosis. METHODS AND RESULTS: Among 78 patients who were diagnosed with AL cardiac amyloidosis at Kumamoto University Hospital from 2007 to 2022, 72 patients with sufficient two-dimensional speckle tracking imaging data without chemotherapy before the diagnosis were retrospectively analysed. During a median follow-up of 403 days, 31 deaths occurred...

BACKGROUND: Acute kidney injury (AKI) is a common complication after surgery and is associated with detrimental outcomes. This systematic review and meta-analysis evaluated perioperative dexmedetomidine on AKI and renal function after non-cardiac surgery. METHODS: PubMed, Embase, and Cochrane Library databases were searched until August 2023 for randomised trials comparing dexmedetomidine with normal saline on AKI and renal function in adults undergoing non-cardiac surgery...

IMPORTANCE: Continuous kidney replacement therapy (CKRT) is increasingly used in youths with critical illness, but little is known about longer-term outcomes, such as persistent kidney dysfunction, continued need for dialysis, or death. OBJECTIVE: To characterize the incidence and risk factors, including liberation patterns, associated with major adverse kidney events 90 days after CKRT initiation (MAKE-90) in children, adolescents, and young adults. DESIGN, SETTING, AND PARTICIPANTS: This international, multicenter cohort study was conducted among patients aged 0 to 25 years from The Worldwide Exploration of Renal Replacement Outcomes Collaborative in Kidney Disease (WE-ROCK) registry treated with CKRT for acute kidney injury or fluid overload from 2015 to 2021...

BACKGROUND: In 2021, a new Chronic Kidney Disease Epidemiology (CKD-EPI) Collaboration equation was introduced that excluded race correction. We set out to compare estimated glomerular filtration rate (eGFR) determined using the creatinine-based CKD-EPI 2009 and 2021 equations and the reclassification of chronic kidney disease (CKD) eGFR staging to explore the potential ramifications of adopting the 2021 equation on reported eGFR and CKD staging. METHODS: We analyzed secondary data previously utilized to determine reference intervals among Black African individuals residing in urban towns in Kenya...

BACKGROUND: Acute kidney injury (AKI) is a common complication postheart transplantation and is associated with significant morbidity and increased mortality. METHODS: We conducted a single-center, retrospective, observational cohort study of 109 consecutive patients undergoing heart transplantation between September 2019 and September 2021 to determine major risk factors for, and the incidence of, severe postoperative AKI as defined by Kidney Disease Improving Global Outcomes criteria in the first 48-h posttransplantation and the impact that this has on mortality and dialysis dependence...

BACKGROUND: The association between surgical treatment of mitral regurgitation (MR) and renal function is not sufficiently well-known. We tried to evaluate renal function before and after the procedure of surgical mitral valve repair (SMVR) in degenerative severe MR. METHODS: Patients with primary severe (4+) MR and normal left ventricular ejection fraction (LVEF) that underwent SMVR, examined by a cutting-edge 3-dimensional (3D) echocardiographic probe were enrolled in this study...

INTRODUCTION: Kidney disease is a well-known extraintestinal manifestation (EIM) associated with inflammatory bowel disease (IBD), with a variety of underlying etiologies. However, little is known about the overall outcomes and predictors. METHODS: This is a retrospective, observational cohort study. Patients with IBD in whom a native kidney biopsy was performed at Mayo Clinic (Rochester, MN) between 1994 and 2022, were included. Demographic, clinical, and histologic characteristics of prognostic interest were collected...

Water reuse is a growing global reality. In regulating water reuse, viruses have come to the fore as key pathogens due to high shedding rates, low infectious doses, and resilience to traditional wastewater treatments. To demonstrate the high log reductions required by emerging water reuse regulations, cost and practicality necessitate surrogates for viruses for use as challenge organisms in unit process evaluation and monitoring. Bacteriophage surrogates that are mitigated to the same or lesser extent than viruses of concern are routinely used for individual unit process testing...

BACKGROUND: The incidence of chronic kidney disease among patients with diabetes mellitus (DM) remains a global concern. Long-term obesity is known to possibly influence the development of type 2 diabetes mellitus. However, no previous meta-analysis has assessed the effects of body mass index (BMI) on adverse kidney events in patients with DM. AIM: To determine the impact of BMI on adverse kidney events in patients with DM. METHODS: A systematic literature search was performed on the PubMed, ISI Web of Science, Scopus, Ovid, Google Scholar, EMBASE, and BMJ databases...
