Examining the Workability, Mechanical, and Thermal Characteristics of Eco-Friendly, Structural Self-Compacting Lightweight Concrete Enhanced with Fly Ash and Silica Fume.

This study compares the workability, mechanical, and thermal characteristics of structural self-compacting lightweight concrete (SCLWC) formulations using pumice aggregate (PA), expanded perlite aggregate (EPA), fly ash (FA), and silica fume (SF). FA and SF were used as partial substitutes for cement at a 10% ratio in various mixes, impacting different aspects: According to the obtained results, FA enhanced the workability but SF reduced it, while SF improved the compressive and splitting tensile strengths more than FA. EPA, used as a fine aggregate alongside PA, decreased the workability, compressive strength, and splitting tensile strength compared to the control mix (K0).

COVID-19: mortality rates of patients on hemodialysis and peritoneal dialysis.

Objective: Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection might have a higher mortality rate in patients with end-stage renal disease due to immunosuppression. This study investigates the mortality rates of SARS-CoV-2 infection and the factors affecting mortality among patients who were on maintenance hemodialysis and continuous ambulatory peritoneal dialysis.

Materials And Methods: A total of 200 patients, including 157 maintenance hemodialysis and 43 continuous ambulatory peritoneal dialysis patients followed in our hospital, were included in the study.

25-Hydroxy vitamin D level is associated with sleep disturbances in patients with chronic kidney disease on hemodialysis: a cross-sectional study.

Background/aim: Deficient levels of vitamin D are an important factor in the pathogenesis of some neurodegenerative diseases. The aim of this study is to determine the relationship between vitamin D deficiency and depression status and sleep disorders of patients on dialysis.

Materials And Methods: In this cross-sectional study, 121 hemodialysis patients were enrolled.

Free triiodothyronine in hemodialysis patients: link with malnutrition and inflammation.

Introduction: Free triiodothyronine (FT3) is a marker of comorbidity in end-stage renal disease and in many acute and chronic diseases. There is lack of data about the link between FT3 levels and malnutrition and inflammation in hemodialysis patients. The objective of the present study was to investigate the link between FT3 and malnutrition and inflammation in hemodialysis patients.
