Multi-site #microbiota alteration is a hallmark of kidney #stone formation

Inquiry of microbiota involvement in kidney stone disease (KSD) has largely focussed on potential oxalate handling abilities by gut bacteria and the increased association with antibiotic exposure. By systematically comparing the gut, urinary, and oral microbiota of 83 stone formers (SF) and 30 healthy controls (HC), we provide a unified assessment of the bacterial contribution… Continue reading Multi-site #microbiota alteration is a hallmark of kidney #stone formation

Detecting Severe #AKI in Hospitalized Patients with Biomarkers of Kidney Injury – A Physician’s Guide to Precision Diagnosis

Acute Kidney Injury (AKI) is a critical concern in hospitalized patients, associated with increased morbidity, mortality, and healthcare costs. The ability to detect AKI early and accurately is paramount for timely intervention and improved patient outcomes. In this post, I embark on a physician’s journey to explore the world of biomarkers for kidney injury, shedding… Continue reading Detecting Severe #AKI in Hospitalized Patients with Biomarkers of Kidney Injury – A Physician’s Guide to Precision Diagnosis

#Choroidal and #retinal thinning in chronic #kidney disease independently associate with eGFR decline and are modifiable with treatment

In patients with chronic kidney disease (CKD), there is an unmet need for novel biomarkers that reliably track kidney injury, demonstrate treatment-response, and predict outcomes. Here, we investigate the potential of retinal optical coherence tomography (OCT) to achieve these ends in a series of prospective studies of patients with pre-dialysis CKD (including those with a… Continue reading #Choroidal and #retinal thinning in chronic #kidney disease independently associate with eGFR decline and are modifiable with treatment

Trajectories of #renal biomarkers and new-onset #heart failure in the general population: Findings from the PREVEND study

Renal dysfunction is one of the most critical risk factors for developing heart failure (HF). However, the association between repeated measures of renal function and incident HF remains unclear. Therefore, this study investigated the longitudinal trajectories of urinary albumin excretion (UAE) and serum creatinine and their association with new-onset HF and all-cause mortality.Methods and resultsUsing… Continue reading Trajectories of #renal biomarkers and new-onset #heart failure in the general population: Findings from the PREVEND study

Association between added #sugars and kidney #stones in U.S. adults: data from National Health and Nutrition Examination Survey 2007–2018

Added sugar is associated with a variety of adverse health outcomes, but its association with kidney stones is unclear. This study was to determine whether added sugar is associated with kidney stones.Materials and methods: This nationally representative study used National Health and Nutrition Examination Survey (NHANES) datasets from 2007 to 2018 for analysis. People aged ≥20 years… Continue reading Association between added #sugars and kidney #stones in U.S. adults: data from National Health and Nutrition Examination Survey 2007–2018

Interferon signaling promotes tolerance to chromosomal instability during metastatic evolution in renal cancer

Molecular routes to metastatic dissemination are critical determinants of aggressive cancers. Through in vivo CRISPR–Cas9 genome editing, we generated somatic mosaic genetically engineered models that faithfully recapitulate metastatic renal tumors. Disruption of 9p21 locus is an evolutionary driver to systemic disease through the rapid acquisition of complex karyotypes in cancer cells. Cross-species analysis revealed that… Continue reading Interferon signaling promotes tolerance to chromosomal instability during metastatic evolution in renal cancer

Longitudinal biomarkers and kidney disease progression after acute kidney injury

BACKGROUND. Longitudinal investigations of murine acute kidney injury (AKI) suggest that injury and inflammation may persist long after the initial insult. However, the evolution of these processes and their prognostic values are unknown in patients with AKI.METHODS. In a prospective cohort of 656 participants hospitalized with AKI, we measured 7 urine and 2 plasma biomarkers of kidney… Continue reading Longitudinal biomarkers and kidney disease progression after acute kidney injury

Population-Wide Screening for Chronic Kidney Disease

Background:Sodium–glucose cotransporter-2 (SGLT2) inhibitors have the potential to alter the natural history of chronic kidney disease (CKD), and they should be included in cost-effectiveness analyses of screening for CKD.Objective:To determine the cost-effectiveness of adding population-wide screening for CKD.Design:Markov cohort model.Data Sources:NHANES (National Health and Nutrition Examination Survey), U.S. Centers for Medicare & Medicaid Services data,… Continue reading Population-Wide Screening for Chronic Kidney Disease

Circulating Extracellular Vesicle-Propagated microRNA Signature as a Vascular Calcification Factor in Chronic Kidney Disease

Background:Chronic kidney disease (CKD) accelerates vascular calcification via phenotypic switching of vascular smooth muscle cells (VSMCs). We investigated the roles of circulating small extracellular vesicles (sEVs) between the kidneys and VSMCs and uncovered relevant sEV-propagated microRNAs (miRNAs) and their biological signaling pathways.Methods and Results:We established CKD models in rats and mice by adenine-induced tubulointerstitial fibrosis.… Continue reading Circulating Extracellular Vesicle-Propagated microRNA Signature as a Vascular Calcification Factor in Chronic Kidney Disease
