ReviewWhy creating standardized core outcome sets for chronic kidney disease will improve clinical practice.
Chronic kidney disease (CKD) is common and is associated with increased mortality, morbidity and cost. However, insufficient high-quality trial data are available to answer many relevant clinical questions in this field. In addition, a wide range of variable outcomes are used in studies, and often they are incompletely reported. ⋯ Common problems with outcome reporting are as follows: choosing the wrong domains to measure; within domains, choosing the wrong measures (invalid surrogates, composite, non-patient relevant); within measures, choosing the wrong/variable metrics; and within metrics, choosing variable presentation methods. With this article, we aim to underline why standardized outcome reporting is key to achieving evidence-based guidance and improving clinical care for patients; highlight the frameworks available for achieving core outcome sets; and starting from these frameworks, we propose steps needed to develop a core outcome set in the field of CKD. We hope that standardized core outcome sets for nephrology will lead to the most important outcome of guideline production, improving outcomes for our patients.

Severe adverse systemic drug events occur commonly as a result of treatment of cancer patients. Nephrotoxicity of chemotherapeutic agents remains a significant complication limiting the efficacy of the treatment. A variety of renal disease and electrolyte disorders can result from the drugs that are used to treat malignant disease. ⋯ Many other drugs such as alkylating agents, antimetabolites, vascular endothelial growth factor pathway inhibitors and epidermal growth factor receptor pathway inhibitors may have toxic effects on the kidneys. The aim of this review is to discuss the issue of nephrotoxicity associated with chemotherapy. In routine clinical practice, monitoring of kidney function is mandatory in order to identify nephrotoxicity early, allowing dosage adjustments or withdrawal of the offending drug.

ReviewRole of biomechanical forces in hyperfiltration-mediated glomerular injury in congenital anomalies of the kidney and urinary tract.
Congenital anomalies of the kidney and urinary tract (CAKUT) including solitary kidney constitute the main cause of progressive chronic kidney disease (CKD) in children. Children born with CAKUT develop signs of CKD only during adolescence and do not respond to renin-angiotensin-aldosterone system blockers. Early cellular changes underlying CKD progression to end-stage renal disease by early adulthood are not well understood. ⋯ Podocytes (i) are mechanosensitive to tensile and shear forces, (ii) use prostaglandin E2, angiotensin-II or nitric oxide for mechanoperception and (iii) use specific signaling pathways for mechanotransduction. We discuss (i) the nature of and differences in cellular responses to biomechanical forces, (ii) methods to study biomechanical forces and (iii) effects of biomechanical forces on podocytes and glomeruli. Future studies on FFSS will likely identify novel targets for strategies for early intervention to complement and strengthen the current regimen for treating children with CAKUT.

Review Meta Analysis Comparative StudyThe efficacy and safety of sevelamer and lanthanum versus calcium-containing and iron-based binders in treating hyperphosphatemia in patients with chronic kidney disease: a systematic review and meta-analysis.
It remains unclear which phosphate binders should be preferred for hyperphosphatemia management in chronic kidney disease (CKD). ⋯ Sevelamer was associated with a nonsignificant reduction in mortality and significantly lower hospitalization rates and hypercalcemia compared with calcium-based binders. However, differences in important outcomes, such as cardiac events, fractures, calciphylaxis, hyperchloremic acidosis and health-related quality of life remain understudied. Lanthanum and iron-based binders did not show superiority for any clinically relevant outcomes. Future studies that fail to measure clinically important outcomes (the reason why phosphate binders are prescribed in the first place) will be wasteful.
