Item Deconstructing Disease-Related Malnutrition: A New Assessment Framework for Clinical Practice(Elsevier, 2023-04-27) St-Jules, David E.; Lloyd, Lyn; Meade, Anthony; Biruete, Annabel; Kistler, Brandon; Carrero, Juan-Jesus; Medicine, School of MedicineProtein-energy wasting (PEW) is a key cause of functional impairment and poor health outcomes in people with chronic kidney disease. While PEW can be mitigated with nutrition therapy, it is a complex myriad of disorders with numerous interacting etiologies and corresponding presentations, which make it difficult to diagnose and manage in practice. A variety of scoring rubrics have been developed to facilitate malnutrition assessment. Although these tools have greatly benefited the recognition and treatment of PEW, the typical format of grading specified PEW indicators has the potential to overlook or overstate highly relevant individual-specific factors. This review presents a simple framework for malnutrition assessment that can be used to complement and evaluate conventional assessment tools. Unlike standard tools, which are designed to identify and rate malnutrition risk and severity, the malnutrition framework is conceptual model that organizes PEW assessment into three distinct, but interacting facets of PEW risk: nutrient balance, nutrition status, and malnutrition risk. The new framework encourages critical thinking about PEW risk that may help clinicians plan and interpret assessments to efficiently and effectively manage this condition.Item New Insights Into Dietary Approaches to Potassium Management in Chronic Kidney Disease(Elsevier, 2023) Sumida, Keiichi; Biruete, Annabel; Kistler, Brandon M.; Khor, Ban-Hock; Ebrahim, Zarina; Giannini, Rossella; Sussman-Dabach, Elizabeth J.; Avesani, Carla Maria; Chan, Maria; Lambert, Kelly; Wang, Angela Yee-Moon; Clegg, Deborah J.; Burrowes, Jerrilynn D.; Palmer, Biff F.; Carrero, Juan-Jesus; Kovesdy, Csaba P.; Nutrition and Dietetics, School of Health and Human SciencesPotassium disorders are one of the most common electrolyte abnormalities in patients with chronic kidney disease (CKD), contributing to poor clinical outcomes. Maintaining serum potassium levels within the physiologically normal range is critically important in these patients. Dietary potassium restriction has long been considered a core strategy for the management of chronic hyperkalemia in patients with CKD. However, this has been challenged by recent evidence suggesting a paradigm shift toward fostering more liberalized, plant-based dietary patterns. The advent of novel potassium binders and an improved understanding of gastrointestinal processes involved in potassium homeostasis (e.g., gastrointestinal potassium wasting) may facilitate a paradigm shift and incorporation of heart-healthy potassium-enriched food sources. Nevertheless, uncertainty regarding the risk-benefit of plant-based diets in the context of potassium management in CKD remains, requiring well-designed clinical trials to determine the efficacy of dietary potassium manipulation toward improvement of clinical outcomes in patients with CKD.
