    Background and objectives: Nutrition intervention is an essential component of kidney disease management. This study aimed to understand current global availability and capacity of kidney nutrition care services, interdisciplinary communication, and availability of oral nutrition supplements. Design, setting, participants, & measurements: The International Society of Renal Nutrition and Metabolism (ISRNM), working in partnership with the International Society of Nephrology (ISN) Global Kidney Health Atlas Committee, developed this Global Kidney Nutrition Care Atlas. An electronic survey was administered among key kidney care stakeholders through 182 ISN-affiliated countries between July and September 2018. Results: Overall, 160 of 182 countries (88%) responded, of which 155 countries (97%) answered the survey items related to kidney nutrition care. Only 48% of the 155 countries have dietitians/renal dietitians to provide this specialized service. Dietary counseling, provided by a person trained in nutrition, was generally not available in 65% of low-/lower middle-income countries and "never" available in 23% of low-income countries. Forty-one percent of the countries did not provide formal assessment of nutrition status for kidney nutrition care. The availability of oral nutrition supplements varied globally and, mostly, were not freely available in low-/lower middle-income countries for both inpatient and outpatient settings. Dietitians and nephrologists only communicated "sometimes" on kidney nutrition care in ≥60% of countries globally. Conclusions: This survey reveals significant gaps in global kidney nutrition care service capacity, availability, cost coverage, and deficiencies in interdisciplinary communication on kidney nutrition care delivery, especially in lower-income countries.

    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 Medicine
    Protein-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.

    Effect of oral nutritional supplementation combined with impedance vectors for dry weight adjustment on the nutritional status, hydration status and quality of life in patients on chronic hemodialysis: A pilot study
    (Elsevier, 2023-04) Nieves-Anaya, Iris; Várgas, Mónica B.; García, Olga P.; Biruete, Annabel; Kistler, Brandon; Atilano-Carsi, Ximena; Medicine, School of Medicine
    Background & aims Protein energy wasting frequently affect hemodialysis patients and contribute to the development of overhydration. The objective of this study was to assess the effect of oral nutritional supplementation (ONS) combined with bioelectrical vector analysis (BIVA) on the nutritional and hydration status and the quality of life (QoL) in hemodialysis (HD) patients. Methods Thirty-two chronic HD patients were included in a 6-month randomized pilot study. Patients in SUPL group received a simultaneous intervention consisting of a personalized diet, 245 mL/d ONS and dry weight adjustment through BIVA. Patients in CON group received a personalized diet and dry weight adjustment by BIVA. Anthropometrical, biochemical, dietary, QoL, handgrip strength (HGS) and bioimpedance measurements were performed. Malnutrition Inflammation Score (MIS) was applied. Results At the end of the intervention, moderate undernutrition decreased by 43.8% in SUPL group while in CON group, severe undernutrition increased by 13 % (p < 0.04 between groups). In the adjusted covariance analysis, SUPL compared to CON group, increased HGS (Δ 2.8 Kg vs Δ -1.8Kg, p=0.003), serum albumin (Δ 0.29 g/dL vs Δ -.03 g/dL, p=0.04) and serum transferrin (Δ 4.7 mg/dL vs Δ -0.7 mg/dL, p=0.0007). The increase in QoL was significantly higher in SUPL group. Dry weight was achieved in 100% of patients in SUPL and 95% in CON group. Conclusions ONS combined with BIVA for dry weight adjustment, improved nutritional status, QoL and achieved dry weight in HD patients.

    Nutritional and Dietary Management of Chronic Kidney Disease Under Conservative and Preservative Kidney Care Without Dialysis
    (Elsevier, 2023) Rhee, Connie M.; Wang, Angela Yee-Moon; Biruete, Annabel; Kistler, Brandon; Kovesdy, Csaba P.; Zarantonello, Diana; Ko, Gang Jee; Piccoli, Giorgina Barbara; Garibotto, Giacomo; Brunori, Giuliano; Sumida, Keiichi; Lambert, Kelly; Moore, Linda W.; Han, Seung Hyeok; Narasaki, Yoko; Kalantar-Zadeh, Kamyar; Medicine, School of Medicine
    While dialysis has been the prevailing treatment paradigm for patients with advanced chronic kidney disease (CKD), emphasis on conservative and preservative management in which dietary interventions are a major cornerstone have emerged. Based on high-quality evidence, international guidelines support the utilization of low-protein diets as an intervention to reduce CKD progression and mortality risk, although the precise thresholds (if any) for dietary protein intake vary across recommendations. There is also increasing evidence demonstrating that plant-dominant low-protein diets reduce the risk of developing incident CKD, CKD progression, and its related complications including cardiometabolic disease, metabolic acidosis, mineral and bone disorders, and uremic toxin generation. In this review, we discuss the premise for conservative and preservative dietary interventions, specific dietary approaches used in conservative and preservative care, potential benefits of a plant-dominant low-protein diet, and practical implementation of these nutritional strategies without dialysis.

    Pilot Study of the Effects of High-Protein Meals During Hemodialysis on Intradialytic Hypotension in Patients Undergoing Maintenance Hemodialysis
    (Elsevier, 2019-03) Choi, Mun Sun; Kistler, Brandon; Wiese, Gretchen N.; Stremke, Elizabeth R.; Wright, Amy J.; Moorthi, Ranjani N.; Moe, Sharon M.; Hill Gallant, Kathleen M.; Medicine, School of Medicine
    Objective Hemodialysis (HD) patients have high protein and energy requirements, and protein-energy wasting is common and associated with poor outcomes. Eating during dialysis may improve nutritional status by counteracting the catabolic effects of hemodialysis treatment; but, eating during HD may be discouraged due to concerns of postprandial hypotension. However, little data is available to support this practice. In this study, we hypothesized that high protein meals during HD does not lead to symptomatic intradialytic hypotension events. Design A 9-week, non-randomized, parallel-arm study. Setting A single in-center HD clinic. Subjects 18 HD patients from two shifts completed the study. Patients were 62±16 years-old in age with dialysis vintage 3.4±2.6 years. Intervention The intervention group (n=9) received meals of ~30g protein and ~1/3 daily recommended intakes of sodium, potassium, phosphorus, and fluid for hemodialysis patients during dialysis for 25 consecutive HD sessions. The control group (n=9) completed all aspects of the study including a visit by study personnel but were not given meals. The 25 consecutive sessions prior to the start of the intervention/control phase were used as a baseline comparison for each patient. Main Outcome Measure Symptomatic hypotension event frequency. Results In the intervention arm, there were 19 symptomatic hypotension events in 5 patients pre-study and 18 events in 6 patients during the study. In the control arm, there were 16 events in 7 patients pre-study and 13 events in 7 patients during the study. Change in the frequency of symptomatic hypotension events from pre-study to during study was not different between groups (P=0.71). There was no effect of meals on nutritional status, but patients reported positive attitudes towards receiving meals during dialysis. Conclusion High-protein meals during HD did not increase symptomatic hypotension events. Larger, longer-term studies are needed to confirm these results and evaluate whether high-protein meals on dialysis benefit nutritional status and clinical outcomes.
