Treating hyperkalemia is one of the main goals of supportive care in patients on hemodialysis. In this context, therapy with new potassium binders is a promising resource. The main aim is to evaluate the difference in serum potassium concentration after treatment with sodium zirconium cyclosilicate or patiromer compared to placebo/sodium polystyrene sulfonate/calcium polystyrene sulfonate. We will perform systematic research in PubMed, EMBASE, CINAHLE, and grey literature will be screened. We will screen RCTs on patients treated with SZC or patiromer in chronic hemodialysis, without sex or age restriction, which include the differences in serum potassium concentration, adverse events (AEs), and mortality as outcomes. This systematic review is expected to provide a comprehensive evaluation of the efficacy and adverse effects of new potassium binders, compared to sodium polystyrene sulfonate or calcium polystyrene sulfonate or placebo, on serum potassium concentration, in a sample of hemodialysis patients. Furthermore, possible gaps in actual knowledge can be highlighted, suggesting new research. The present protocol for a systematic review will consider all existing evidence from published RCTs about the efficacy of HIF-PHIs on hemodialysis patients.

Background: Patients with both heart failure (HF) and chronic kidney disease (CKD) are often treated with renin-angiotensin-aldosterone system inhibitors (RAASi), but these drugs can cause hyperkalemia, which may lead to their reduction or discontinuation, resulting in the loss of their beneficial effects. Approaches to managing RAASi-induced hyperkalemia are discordant, so in this study we aimed to establish a cross-specialty consensus on the optimal approach to managing hyperkalemia in patients with HF and CKD.

Methods And Results: The study used a modified Delphi methodology.

Industrial waste recycling approach: An ecofriendly geopolymer binder for clean and sustainable environments (A 24-h green recycling process).

J Environ Manage

March 2025

Instituto de Investigaciones en Materiales, Universidad Nacional Autónoma de México, Circuito exterior s/n, Ciudad Universitaria, Del. Coyoacán, Ciudad de México, CP 04510, Mexico.

Bypass cement waste dust (BCWD) significantly threatens human health and the environment due to its high concentrations of fine, respirable crystalline silica, chlorine, and sulfates. This study introduces an eco-friendly recycling approach that processes BCWD at a low temperature of 80 °C for 24 h. The method combines 50% BCWD with an equal proportion of natural black volcanic ash (BVA) and varying concentrations of NaOH to produce an innovative material known as Green Geopolymer Bypass Binder (GGBB).

Olive Pomace Fly Ash as an Alternative Alkaline Activator for Electric Arc Furnace Slag for Sustainable Cementitious Materials.

Materials (Basel)

January 2025

Department of Chemical, Environmental, and Materials Engineering, Higher Polytechnic School of Jaén, Campus Las Lagunillas, University of Jaén, s/n, 23071 Jaen, Spain.

This study analyzes the potential of olive pomace fly ash (OPFA) as an alternative alkaline activator for electric arc furnace slag (EAFS) in the manufacture of sustainable cementitious materials. Cements were prepared by replacing 30-50 wt% of EAFS with OPFA and compared with control cements activated with potassium hydroxide (KOH) at concentrations of 4 and 8 M. Cements were characterized by bulk density, water absorption, total porosity, compressive and flexural strength, as well as analytical techniques such as XRD, FTIR and SEM-EDS.
