Association Between Myocardial Work and Coronary Artery Calcium Score in Patients With Chronic Kidney Disease.

Background: Myocardial work is a novel measure of potential value for diagnosing coronary artery disease (CAD). It may therefore be useful in patients with chronic kidney disease (CKD), in whom the diagnostic work-up can be challenging.

Methods: This was a cross-sectional study of patients with CKD (G1-5, nondialysis-dependent).

Bone mineral density and the risk of kidney disease in patients with type 1 diabetes.

Aim: To explore the association between bone disorder and the risk for progression of diabetic kidney disease (DKD) in persons with type 1 diabetes mellitus (T1DM).

Methods: In this prospective cohort study the association between bone mineral density (BMD), bone-derived factors (sclerostin, Dickkopf-1, and osteoprotegerin (OPG)), and four outcomes were investigated: 1) progression of albuminuria; 2) decline in estimated glomerular filtration rate (eGFR) ≥30 %; 3) kidney failure (KF); and 4) a composite kidney outcome consisting of at least one of the outcomes.

Results: In 318 participants (median follow-up time 5.

Osteocalcin: A bone protein with multiple endocrine functions.

Bones are now recognised as endocrine organs with diverse functions. Osteocalcin, a protein primarily produced by osteoblasts, has garnered significant attention. Research into osteocalcin has revealed its impact on glucose metabolism and its unexpected endocrine role, particularly in its undercarboxylated form (ucOC).

Cohort profile: the PRIMETIME 1 (PRecIsion MEdicine based on kidney TIssue Molecular interrogation in diabetic nEphropathy) cohort - a longitudinal Danish nationwide study of individuals with diabetes and a performed kidney biopsy.

Purpose: Individuals with diabetes and chronic kidney disease are at high risk of kidney failure, cardiovascular events and premature mortality and more research is warranted to further improve the prevention and management of complications. The PRecIsion MEdicine based on kidney TIssue Molecular interrogation in diabetic nEphropathy (PRIMETIME) 1 cohort is designed to study clinical characteristics, diagnostic accuracy and prognostic markers in a population with diabetes and kidney disease classified by biopsy.

Participants: This retrospective Danish nationwide cohort includes 2586 individuals with diabetes who have undergone a kidney biopsy between the 1980s and 2022.

The validity of pathology codes for biopsy-confirmed kidney disease in the Danish National Patobank.

Background: This study validates the application of Systematized Nomenclature of Medicine second edition (SNOMED II) codes used to describe medical kidney biopsies in Denmark in encoded form, aiming to support robust epidemiological research on the causes, treatments and prognosis of kidney diseases.

Methods: Kidney biopsy reports from 1 January 1998 to 31 December 2018 were randomly extracted from the Danish National Patobank, using SNOMED codes. A 5% sample was selected, and nephrologists assessed the corresponding medical records, assigning each case the applied clinical diagnoses.

Myocardial work in chronic kidney disease: insights from the CPH-CKD ECHO Study.

Background: Myocardial work is a novel echocardiographic measure that offers detailed insights into cardiac mechanics. We sought to characterize cardiac function by myocardial work in patients with chronic kidney disease (CKD).

Methods: We prospectively enrolled 757 patients with non-dialysis-dependent CKD and 174 age- and sex-matched controls.

The role of aetiology in cardiac manifestations of chronic kidney disease: the CPH-CKD ECHO study.

Purpose: We investigated the associations between cardiac parameters and aetiologies of CKD in an exploratory study.

Methods: The study population consisted of 883 participants, 174 controls and 709 patients with aetiologies of CKD including diabetic nephropathy/renovascular KD in diabetes mellitus, hypertensive/renovascular nephropathy, tubulointerstitial nephritis, glomerulonephritis/vasculitis, polycystic KD (PKD), and CKD of unknown origin. Echocardiographic measures included left ventricular (LV) ejection fraction, global longitudinal, area, and radial strain, E/e' ratio, and LV mass index.

Protocol for a randomised controlled trial comparing warfarin with no oral anticoagulation in patients with atrial fibrillation on chronic dialysis: the Danish Warfarin-Dialysis (DANWARD) trial.

Introduction: Atrial fibrillation is highly prevalent in patients on chronic dialysis. It is unclear whether anticoagulant therapy for stroke prevention is beneficial in these patients. Vitamin K-antagonists (VKA) remain the predominant anticoagulant choice.

Shared and Distinct Renal Transcriptome Signatures in 3 Standard Mouse Models of Chronic Kidney Disease.

Introduction: Several mouse models with diverse disease etiologies are used in preclinical research for chronic kidney disease (CKD). Here, we performed a head-to-head comparison of renal transcriptome signatures in standard mouse models of CKD to assess shared and distinct molecular changes in three mouse models commonly employed in preclinical CKD research and drug discovery.

Methods: All experiments were conducted on male C57BL/6J mice.

No Detectable Coagulation Activation After Vitamin K (MK-7) Supplementation in Patients on Dialysis With Functional Vitamin K Deficiency: A One-Year Randomized, Placebo-Controlled Study.

Objective: Patients on dialysis treatment have poor functional vitamin K status, and this may increase the risk of vascular calcification. Vitamin K supplementation may therefore be relevant in patients on dialysis, but the procoagulant effects have not been studied. We evaluated effects of menaquinone-7 (MK-7) supplementation on biomarkers of coagulation in patients on dialysis.

Design and methodology of the PRIMETIME 1 cohort study: PRecIsion MEdicine based on kidney TIssue Molecular interrogation in diabetic nEphropathy.

Background: Clinical features of diabetic kidney disease alone cannot differentiate between the histopathology that defines diabetic nephropathy (DN) and non-diabetic nephropathy (NDN). A kidney biopsy is necessary to make the definitive diagnosis of DN. However, there is no consensus on when to perform a kidney biopsy in individuals with diabetes and kidney disease.

Recommended calcium intake in adults and children with chronic kidney disease-a European consensus statement.

Mineral and bone disorders (MBD) are common in patients with chronic kidney disease (CKD), contributing to significant morbidity and mortality. For several decades, the first-line approach to controlling hyperparathyroidism in CKD was by exogenous calcium loading. Since the turn of the millennium, however, a growing awareness of vascular calcification risk has led to a paradigm shift in management and a move away from calcium-based phosphate binders.

Cutaneous vascular calcifications in patients with chronic kidney disease and calcific uremic arteriolopathy: a cross-sectional study.

Introduction: Calcific uremic arteriolopathy is a life-threatening cutaneous condition in patients with chronic kidney disease. Often, clinical diagnosis is accompanied by histopathologic evaluations demonstrating vascular calcium deposits. We aimed to investigate the presence of cutaneous calcifications in non-lesional tissue in patients with chronic kidney disease, and the relation to systemic vascular calcification.

Bone Turnover in Patients with Chronic Kidney Disease Stage 5D and Healthy Controls - a Quantitative [F]Fluoride PET Study.

Background: Chronic kidney disease (CKD) is prevalent in the aging population and increases the risk of fracture 2-4 times. We compared optimized quantitative [F]fluoride PET/CT methods to the reference standard with arterial input function (AIF) to identify a clinically accessible method for evaluation of bone turnover in patients with CKD.

Methods: Ten patients on chronic hemodialysis treatment and ten control patients were recruited.

Rationale and design of a prospective, clinical study of kidney biopsies in people with type 2 diabetes and severely increased albuminuria (the PRIMETIME 2 study).

Introduction: Diabetic kidney disease is a severe complication of diabetes. The diagnosis is based on clinical characteristics such as persistently elevated albuminuria, hypertension and decline in kidney function, although this definition is not specific to kidney disease caused by diabetes. The only way to establish an accurate diagnosis-diabetic nephropathy-is by performing a kidney biopsy.

The Danish newborn standard and the International Fetal and Newborn Growth Consortium for the 21st Century newborn standard: a nationwide register-based cohort study.

Background: It is a matter of debate whether 1 universal standard, such as the International Fetal and Newborn Growth Consortium for the 21st Century standard, can be applied to all populations.

Objective: The primary objective was to establish a Danish newborn standard based on the criteria of the International Fetal and Newborn Growth Consortium for the 21st Century standard to compare the percentiles of these 2 standards. A secondary objective was to compare the prevalence and risk of fetal and neonatal deaths related to small for gestational age defined by the 2 standards when used in the Danish reference population.

Far infrared treatment on the arteriovenous fistula induces changes in sVCAM and sICAM in patients on hemodialysis.

Introduction: There is a substantial risk of developing stenosis and dysfunction in the arteriovenous fistula (AVF) in patients on hemodialysis (HD). Far infrared radiation (FIR) is a non-invasive local intervention with a potentially beneficial effect on AVF patency. The underlying mechanism is not clear.

Combination therapy with immune check point inhibitors and acute kidney injury.

Background: Immune checkpoint inhibitors have revolutionized the treatment of metastatic renal cell carcinoma and malignant melanoma but are also associated with a risk of severe side effects. Nephrotoxicity is an immune checkpoint inhibitor-related adverse effect, but acute kidney injury (AKI) can also be caused by other more common conditions. This study aimed to describe the incidence and causes of AKI in patients treated with combination therapy of immune checkpoint inhibitors.

The Effect of Magnesium Supplementation on Vascular Calcification in CKD: A Randomized Clinical Trial (MAGiCAL-CKD).

Significance Statement: Magnesium prevents vascular calcification in animals with CKD. In addition, lower serum magnesium is associated with higher risk of cardiovascular events in CKD. In a randomized, double-blinded, placebo-controlled trial, the authors investigated the effects of magnesium supplementation versus placebo on vascular calcification in patients with predialysis CKD.

Effects of Dapagliflozin on EChOcardiographic Measures of CarDiac StructurE and Function in Patients with Chronic Kidney Disease: The DECODE-CKD Trial.

Key Points: SGLT2 inhibitors (SGLT2i) exert cardioprotective effects in patients with CKD through unknown mechanisms. DECODE-CKD is the first randomized controlled trial (RCT) to evaluate the effects of SGLT2i on cardiac structure and function in patients with CKD.

Background: SGLT2 inhibitors, originally developed as glucose-lowering agents for treatment of type 2 diabetes, have been shown to have cardio- and kidney-protective effects among CKD patients with and without diabetes.
