Unlabelled: This study was intended to investigate the microcirculation endothelial dysfunction through a laser Doppler method (PORH post-occlusive reactive hyperemia) in patients with chronic kidney disease.
Materials And Methods: The study included 299 patients diagnosed with chronic kidney disease, which were divided into three groups: hemodialysis patients, peritoneal dialysis patients and patients with chronic kidney disease stages 3-4. Endotelial dysfunction was assesed with the Laser Doppler Perfusion Monitor type device (Periflux System Monitor 5001).
Results: The values of the parameters we evaluated with postocclusive reactive hyperemia were altered in all patients with chronic kidney disease. In the dialysis groups there was no statistically significant correlation between parameters we tested by measuring PORH and the method of renal replacement therapy or dialysis duration. The same was observed in patients with pre-dialysis chronic kidney disease.
Conclusions: Post-occlusive reactive hyperemia, a novel method for assessing endothelial dysfunction on the microcirculatory system and early marker of cardiovascular damage requires more studies to validate in patients advanced renal disfunction.

Identifying Research Priorities for Cognition in CKD: A Delphi Study.
Kidney360
January 2025
University of Manitoba, Winnipeg, MB, Canada.
Background: Cognition is a research priority for people living with chronic kidney disease (CKD), but identification of critical research questions is lacking. This study aimed to determine which cognition-related research questions are most important to CKD stakeholders.
Methods: A modified Delphi technique with 3 survey rounds was used.
Associations between dialysis modality and adherence to immunosuppression after kidney transplantation-A single-center study.
PLoS One

Helsinki University Hospital, Abdominal Centre, Transplantation and Liver Surgery, and University of Helsinki, Helsinki, Finland.
Background: Patients with end-stage kidney disease often prefer home-based dialysis due to higher self-efficacy, which relates to improved medical treatment adherence. Kidney transplantation (KT) success depends on adhering to immunosuppressive medication post-transplant.
Objectives: To investigate whether adherence post-kidney transplantation (KT) and patients' attitudes toward immunosuppression were influenced by their prior dialysis type modality.
Association of chronic kidney disease with acute clinical outcomes and hospitalization costs of cancer resection.
PLoS One
January 2025
Cardiovascular Outcomes Research Laboratories (CORELAB), University of California, Los Angeles, Los Angeles, CA, United States of America.
Purpose: Patients with chronic kidney disease (CKD) and end-stage renal disease (ESRD) have been noted to face increased cancer incidence. Yet, the impact of concomitant renal dysfunction on acute outcomes following elective surgery for cancer remains to be elucidated.
Methods: All adult hospitalizations entailing elective resection for lung, esophageal, gastric, pancreatic, hepatic, or colon cancer were identified in the 2016-2020 National Inpatient Sample.
Iodinated Contrast Adsorption in Cartridges With Styrene-Divinylbenzene Sorbent.
Artif Organs

International Renal Research Institute of Vicenza (IRRIV), Vicenza, Veneto, Italy.
Background: Contrast-associated acute kidney injury (CA-AKI) is frequent in patients with chronic kidney disease who are submitted to cardiac endovascular procedures using iodinated contrast. In hemoadsorption, cartridges containing styrene-divinylbenzene sorbent resin are applied to remove substances from the blood through an extracorporeal circuit. Importantly, iodinated contrast is also removed via adsorption.

This study aimed to assess the correlation between estimated pulse wave velocity (ePWV) and mortality rates related to all-cause and cardiovascular disease (CVD) among individuals diagnosed with chronic kidney disease (CKD) in the United States. A total of 4669 participants with CKD were identified from the National Health and Nutrition Examination Survey conducted between 1999 and 2018. We calculated the incidence of CKD using an estimated glomerular filtration rate (eGFR) of < 60 mL/min/1.
