AI Article Synopsis
Article Abstract
Background: Cardiovascular disease in chronic kidney disease (CKD) has peculiar characteristics. The aim of this study was to analyze atherosclerosis, vascular calcification and nitration in arteries from CKD patients.
Methods: External iliac and renal artery segments from 27 stage 5 CKD patients and 25 donor controls, respectively, were collected during the transplantation procedure.
Results: CKD patients presented a significantly higher degree of lesion. In a large proportion (72%) of CKD patients, we observed vascular calcifications. Immunohistochemistry for nitrotyrosine revealed a significant increase in nitrotyrosine production in arteries from CKD patients compared with control donors. In addition, within CKD patients, nitrotyrosine staining was significantly stronger in arteries with media calcification when compared with arteries without media calcification.
Conclusion: The arteriopathy in the CKD patients appears in an early age and seems to be distinct from the arteriopathy of the general population, especially due to intense calcification and vascular oxidative stress.

Physiologic insulin resensitization lowers cost in patients with diabetes and kidney disease.
Am J Manag Care
January 2025
McGovern Medical School at UTHealth Houston, 4513 Teas St, Bellaire, TX 77401.
Objective: To examine the effect of physiologic insulin resensitization (PIR) on the cost of treating patients with diabetes and chronic kidney disease (CKD).
Study Design: The mean 1-year cost of treating 66 Medicare Advantage patients with diabetes and CKD who were receiving PIR was compared with that of treating 1301 Medicare Advantage patients with diabetes and CKD not receiving PIR. Differences in disease severity were compared using mean risk adjustment factor scores.

Nephrology Division, University of Washington, Seattle, WA; Providence Medical Research Center, Providence Inland Northwest Health, Spokane, WA.
Background: Chronic limb-threatening ischemia (CLTI) in patients with chronic kidney disease (CKD) has a high risk of poor outcomes. We aimed to compare the outcomes of lower extremity revascularization in patients with CLTI stratified by CKD severity in patients enrolled in the prospective, randomized Best Endovascular vs Best Surgical Therapy in Patients with CLTI (BEST-CLI) trial.
Methods: The BEST-CLI trial dataset was queried to categorize patients into three groups according to CKD stage.
Canagliflozin reduces oral loop diuretic intensification in patients with type 2 diabetes: A participant-level pooled analysis of the CANVAS and CREDENCE trials.
Eur J Heart Fail

The George Institute for Global Health, University of New South Wales, Sydney, NSW, Australia.
Aims: The sodium-glucose cotransporter 2 inhibitor canagliflozin reduces the risk of heart failure (HF) hospitalization or cardiovascular death and chronic kidney disease (CKD) progression among patients with type 2 diabetes at high cardiovascular risk or with CKD. Patients with type 2 diabetes commonly have coexisting HF or CKD that require treatment with loop diuretics; however, the prognostic implications of oral loop diuretic intensification are not well characterized.
Methods And Results: In this participant-level pooled analysis of the CREDENCE and CANVAS trials (not including CANVAS-R), 1454/8731 (16.
High prevalence of unrecognized chronic kidney disease in the Lolland-Falster Health Study: a population-based study in a rural provincial area of Denmark.
Eur J Public Health

Department of Nephrology and Endocrinology, Rigshospitalet, Copenhagen, Denmark.
Chronic kidney disease (CKD) affects 10-15% globally and is a marked independent risk factor for cardiovascular disease. Prevalence estimations are essential for public health planning and implementation of CKD treatment strategies. This study aimed to estimate the prevalence and stages of CKD in the population-based Lolland-Falster Health Study, set in a rural provincial area with the lowest socioeconomic status in Denmark.

Background: It is clinically relevant to predict outcomes in dogs with acute kidney injury (AKI) treated with haemodialysis. The aim of this study was to evaluate the prognostic value of contrast-enhanced ultrasound (CEUS) and its role in discriminating between AKI and acute impairment associated with chronic kidney disease (AKI/CKD).
Methods: Dogs diagnosed with AKI or AKI/CKD were prospectively enrolled in the study.
