New Insights Into Dietary Approaches to Potassium Management in Chronic Kidney Disease. J Ren Nutr 2023; 33:S6-S12. [PMID: 37610407 PMCID: PMC10872890 DOI: 10.1053/j.jrn.2022.12.003] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/06/2022] [Revised: 10/07/2022] [Accepted: 12/13/2022] [Indexed: 08/24/2023] Open
Abstract
Potassium 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.

Abstract
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.

Effects of Sodium-Specific Medical Nutrition Therapy from a Registered Dietitian Nutritionist in Individuals with Chronic Kidney Disease: An Evidence Analysis Center Systematic Review and Meta-Analysis. J Acad Nutr Diet 2021; 122:445-460.e19. [PMID: 33941476 DOI: 10.1016/j.jand.2021.03.016] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/19/2020] [Revised: 03/18/2021] [Accepted: 03/25/2021] [Indexed: 11/15/2022]
Abstract
Dietary sodium intake can increase risk of hypertension, a leading cause of kidney failure in individuals with chronic kidney disease. The objective of this systematic review was to examine the effect of sodium-specific medical nutrition therapy provided by a registered dietitian nutritionist or international equivalent on blood pressure and urinary sodium excretion in individuals with chronic kidney disease, stages 2 through 5, receiving maintenance dialysis and posttransplant. Medline, the Cumulative Index to Nursing and Allied Health Literature, Cochrane Cochrane Central Register of Controlled Trials, and other databases were searched to identify eligible controlled trials published in the English language from January 2000 until June 2020 that addressed the research question. Risk of bias was assessed using the RoB 2.0 tool and quality of evidence was examined by outcome using the Grading of Recommendations Assessment, Development, and Evaluation method. Of the 5,642 articles identified, eight studies were included in the final analyses. Six studies targeted clients who were not dialyzed, including one with clients who were posttransplantation, and two studies with clients receiving maintenance hemodialysis. Sodium-specific medical nutrition therapy from a registered dietitian nutritionist significantly reduced clinic systolic blood pressure (mean difference -6.7, 95% CI -11.0 to -2.4 mm Hg; I2 = 51%) and diastolic blood pressure (mean difference -4.8, 95% CI, -7.1 to -2.4 mm Hg; I2 = 23%) as well as urinary sodium excretion (mean difference -67.6, 95% CI -91.6 to -43.6 mmol/day; I2 = 84.1%). Efficacy was limited to individuals who were not dialyzed, including posttransplantation, but the intervention did not significantly improve blood pressure in individuals receiving maintenance hemodialysis. Adults with chronic kidney disease should begin to work with registered dietitian nutritionist early in the course of disease to receive individualized, effective counseling to improve risk factors and, ultimately, health outcomes.

Abstract
The National Kidney Foundation's Kidney Disease Outcomes Quality Initiative (KDOQI) has provided evidence-based guidelines for nutrition in kidney diseases since 1999. Since the publication of the first KDOQI nutrition guideline, there has been a great accumulation of new evidence regarding the management of nutritional aspects of kidney disease and sophistication in the guidelines process. The 2020 update to the KDOQI Clinical Practice Guideline for Nutrition in CKD was developed as a joint effort with the Academy of Nutrition and Dietetics (Academy). It provides comprehensive up-to-date information on the understanding and care of patients with chronic kidney disease (CKD), especially in terms of their metabolic and nutritional milieu for the practicing clinician and allied health care workers. The guideline was expanded to include not only patients with end-stage kidney disease or advanced CKD, but also patients with stages 1-5 CKD who are not receiving dialysis and patients with a functional kidney transplant. The updated guideline statements focus on 6 primary areas: nutritional assessment, medical nutrition therapy (MNT), dietary protein and energy intake, nutritional supplementation, micronutrients, and electrolytes. The guidelines primarily cover dietary management rather than all possible nutritional interventions. The evidence data and guideline statements were evaluated using Grading of Recommendations, Assessment, Development and Evaluation (GRADE) criteria. As applicable, each guideline statement is accompanied by rationale/background information, a detailed justification, monitoring and evaluation guidance, implementation considerations, special discussions, and recommendations for future research.

Renal Dietitians' Perceptions of Roles and Responsibilities in Outpatient Dialysis Facilities. J Ren Nutr 2015; 25:404-11.

Abstract
OBJECTIVE This study was designed to determine what job responsibilities renal dietitians working in outpatient dialysis facilities consider as most important and most time-consuming. We hypothesized that more time-consuming activities would not always be considered most important. DESIGN AND PARTICIPANTS An online survey was sent to 3,382 renal dietitians via professional organization e-mail lists. The survey included 30 activities that renal dietitians perform, grouped into 3 categories (general responsibilities, assessments, and interventions) and based on the National Kidney Foundation-Kidney Disease Outcomes Quality Initiative nutrition guidelines. For each category of activities, respondents were asked to rank the 10 activities from 1 (most important or time-consuming) to 10 (least important or time-consuming). For analysis, the rankings were combined into 3 groups: 1 to 3 = most; 4 to 6 = mid; and 7 to 10 = least important or time-consuming. Demographic and professional questions were also included. RESULTS Four hundred sixty six renal dietitians responded, and represented a broad range of experience in renal dietetics and type of dialysis facility. The mean number of patients per 40 hours full-time equivalent dietitian was 115.5 ± 38.4. There was good agreement between the respondents' ranking of importance and time consumed. Those activities identified as most important were traditional dietitian roles such as diet assessment and nutrition education. Many respondents provided write-in response of other activities they considered important and time-consuming such as communicating with family members or caregivers, enrolling and managing patients in the in-house pharmacy program, and serving as a care coordinator. CONCLUSIONS It appears that the renal dietitian's role of providing nutrition assessments and counseling in outpatient dialysis facilities is being expanded to include administrative and coordination responsibilities. The impact of these changes on patient outcomes is unclear; however, previous research has indicated that administrative responsibilities take away from patient care time and decrease dietitian job satisfaction.

Characteristics of an Effective Preceptor: Dietetics Education as a Paradigm. JOURNAL OF ALLIED HEALTH 2015; 44:229-235.

Abstract
PURPOSE To examine the characteristics of effective preceptors, using the perceptions of students who are enrolled in a Dietetic Internship (DI), and to evaluate the influence of the following factors on preceptor behavior: a preceptors' area of practice, credentials, and type of DI program where the student is enrolled. METHODS Three hundred fifty-one students from 129 randomly selected DI programs completed an online survey to evaluate their preceptors, using a 40-item Preceptor Behavior Scale that included four categories: knowledge and professional competence, interpersonal skills, personality characteristics, and teaching ability. RESULTS The students ranked knowledge and professional competence as the most important category for effective preceptors. Teaching ability had the largest difference in mean scores between an effective and ineffective preceptor. Preceptors who were considered more effective included: a) preceptors in clinical and "other" practice areas such as community and private practice vs those in food service; b) preceptors who were registered dietitians (RD) vs non-RD; and c) preceptors in hospital-based DI programs vs university-based DI programs. CONCLUSIONS Preceptor training should emphasize skills in all of the categories from the Preceptor Behavior Scale so that preceptors can effectively help students meet the competencies required for entry-level practice. A web-based preceptor training module that can reach offsite preceptors should be developed that includes scenarios for all areas of practice, teaching skills based on the principles of adult learning, and a credential and/or a professional incentive.

Abstract
BACKGROUND Poor nutritional status has been associated with worse patient survival in maintenance hemodialysis patients. Anthropometric values are important nutritional measures, incorporating muscle and fat mass. However, the association of changes in anthropometry, including midarm circumference (MAC) and skinfold measurements, with mortality in hemodialysis patients remains unknown. Accordingly, we explored this association in the Hemodialysis (HEMO) Study. STUDY DESIGN Post hoc analysis of cohort data from a clinical trial. SETTING & PARTICIPANTS 1,846 hemodialysis patients enrolled in the HEMO Study. PREDICTORS MAC and skinfold measurements. OUTCOMES Longitudinal changes in MAC and skinfolds were jointly modeled using repeated measures and survival modeling. Time-to-event outcomes were all-cause mortality, cardiac death and hospitalization, and infection-related death. RESULTS Mean MAC was 30.1 cm, and mean baseline sum of subscapular, biceps, and triceps skinfolds was 42.4 mm. During a median follow-up of 2.5 years, there were 845 deaths. During follow-up, MAC and the skinfold measurement declined 0.26 cm and 1.1 mm per year, respectively. Declines in MAC (per cm) and skinfold (per mm) measurements were associated with higher all-cause mortality (HRs of 1.58 [95% CI, 1.29-1.94; P < 0.001] and 1.06 [95% CI, 0.99-1.13; P = 0.09], respectively), poorer cardiac outcomes (HRs of 1.49 [95% CI, 1.23-1.81; P < 0.001] and 1.05 [95% CI, 0.99-1.10; P = 0.09], respectively), and higher infection-related hospitalization (HRs of 2.45 [95% CI, 1.55-3.88; P < 0.001] and 1.16 [95% CI, 0.98-1.37; P = 0.08], respectively). The association between declining MAC and skinfold with patient survival was most notable for those with body mass index (BMI) ≤25 kg/m2 (HRs of 2.41 [95% CI, 1.81-3.19; P < 0.001] and 1.22 [95% CI, 1.10-1.35; P < 0.001], respectively). LIMITATIONS Prevalent dialysis patients only, excluding individuals weighing >85 kg. CONCLUSIONS Declines in skinfold thickness were not associated significantly with outcomes except for participants with BMI ≤25 kg/m2. Declines in MAC are associated significantly with all-cause mortality and cardiac outcomes in hemodialysis patients, most notably in those with BMI ≤25 kg/m2.

Abstract
OBJECTIVES The study objective was to identify the factors that influence dietary adherence in Hispanic patients receiving maintenance hemodialysis and to determine the differences in dietary adherence between Hispanic and non-Hispanic patients. DESIGN We performed a cross-sectional study using a descriptive-comparative design. SETTING The study took place at hemodialysis centers at Winthrop-University Hospital, New York. PARTICIPANTS The participants were adult patients of Hispanic descent receiving maintenance hemodialysis three times per week for 3 months or more and an equal number of age- and sex-matched non-Hispanic patients. INTERVENTION Information was obtained by a questionnaire about knowledge of the diet, preferred language for education, consumption of potassium- (K(+)) and phosphorus- (PO(4)) containing foods, and adherence attitudes and behaviors. Serum albumin (SAlb), K(+), and PO(4) for the past 3 months were obtained from medical records and evaluated to assess dietary adherence. MAIN OUTCOME MEASURE The main outcome measure was a mean SAlb of 3.2g/dL or greater, K(+) of 5.5 mEq/L or less, and PO(4) of 5.5 mg/dL or less. RESULTS A total of 17 Hispanic and 17 comparison patients were included. Both groups were adherent to the diet because their mean levels of SAlb, K(+), and PO(4) were within acceptable limits. Dietary adherence was observed in 76% of the Hispanic patients for SAlb, 88% for K(+), and 65% for PO(4), whereas the rate of adherence was 59%, 88%, and 76%, respectively, for the comparison group. CONCLUSION Both groups were adherent to the restrictions of the renal diet. More patients from both groups were adherent to K(+) than to PO(4) restrictions. Among the factors that probably influenced dietary adherence to the renal diet in this dialysis facility are knowledge of the renal diet, language, food frequency consumption, socioeconomic status, family support, and attitudes toward the renal diet. Patient education provided in Spanish with family involvement is an important element for promoting adherence among Hispanic patients receiving dialysis.

Abstract
OBJECTIVES To determine analytically the amount of potassium in raw tuberous root vegetables (TRV); to estimate the amount of potassium that can be leached from raw TRV by soaking in water; and to determine whether the duration of soaking and the cooking method selected affect potassium extraction. DESIGN Fresh TRV (ie, fresh and sweet batata, cocomalanga, dasheen, eddo, black yam, white yam, yellow yam, yampi, malanga, red yautia, white yautia, and yuca) were obtained from an ethnic market. Five experimental conditions with variations in soak time and cooking method were applied. Potassium was extracted from the ash of dried samples. The potassium content of aqueous extractions was determined through atomic absorption spectrophotometry. RESULTS Mean potassium content was highest in raw cocomalanga and lowest in raw dasheen. All of the raw TRV, except for dasheen, had a potassium content >200 mg (5.1 mEq)/100 g sample. Soaking was not effective in the leaching of significant amounts of potassium from most TRV. The double cooking (DC) method (ie, boil, rinse, boil again) leached more potassium from most TRV than did the normal cooking (NC) method (ie, boil), except with dasheen and yellow yam. More vegetables retained a potassium content >200 mg (5.1 mEq)/100 g following NC versus DC (92% versus 54%). CONCLUSIONS The potassium content of raw TRV varied considerably, with most tubers retaining a moderate or high potassium content following the leaching procedures. However, this study showed that DC appears to be more effective than NC for leaching potassium from TRV.

Abstract
BACKGROUND Anorexia is an important cause of protein-energy malnutrition (PEM) in haemodialysis patients. We investigated whether self-reported appetite was associated with death and hospitalization in subjects enrolled in the Hemodialysis (HEMO) Study. METHODS The HEMO Study was a 7-year, multicentre, randomized trial (N = 1846), which examined the effects of dialysis dose and membrane flux on mortality and morbidity. Three questions from the Appetite and Diet Assessment Tool (ADAT) were used to determine whether appetite had changed over time in the randomized treatment groups. The relations among ADAT scores, dietary protein and energy intakes, biochemical and anthropometric measures, and quality of life were assessed. We used Cox proportional hazards models to evaluate the relative risks of death and hospitalization associated with static and dynamic ADAT scores, adjusted for demographic factors, dose and flux assignments, and co-morbidity. RESULTS The average length of follow-up was 2.84 years. After adjusting for demographic factors and randomized treatment assignments, there was a significant association between poorer self-reported appetite and death (RR 1.52, 95% CI 1.16-1.98); however, the association became non-significant with further adjustment for co-morbidity (RR 1.23, 95% CI 0.94-1.62). Poorer appetite was unequivocally associated with increased hospitalization rates (multivariable RR 1.35, 95% CI 1.13-1.61). The longitudinal effect of worsening appetite from baseline to 1 year was not associated with mortality or hospitalization rate after adjusting for co-morbidity. CONCLUSIONS The association between appetite and death was confounded by co-morbidity. Self-reported appetite was associated with hospitalization rate in haemodialysis patients and, thus, it may be a useful screening tool for this outcome. Patients who report poor or very poor appetites should be monitored, and they should receive more comprehensive nutritional assessments.

OBJECTIVE We investigated the components of the National Kidney Foundation-Kidney Disease Outcomes Quality Initiative Nutrition Guidelines that are implemented by renal dietitians and the types of resources and support available to assist in implementing these guidelines. DESIGN AND PARTICIPANTS A 49-item survey was mailed to 1694 dietitians in the United States. who were members of the National Kidney Foundation Council on Renal Nutrition in June 2003. The survey included sections on clinical practice, tools available to perform nutrition assessments, daily activities of the dietitian, and demographic and professional questions. RESULTS Of the 1694 surveys mailed, 951 were returned (56% response rate); 848 were useable (89%). The primary employer was for-profit dialysis units (67%) and the mean (+/- SD) number of patients per dietitian was 104.9 +/- 48.3. Virtually all of the dietitians were aware of the nutrition guidelines (97%); 58% read all of the guidelines, whereas only 41% read some of the guidelines. Ninety-two percent of respondents implemented at least one guideline in their clinical practice; 72% and 55% had implemented 5 and 10 guidelines, respectively; but only 5% implemented all of the guidelines. Several barriers to implementation included lack of tools such as computers, calipers, and food models (57%); inadequate time including high dietitian-to-patient ratios (40%); and lack of administrative support from the dialysis unit (29%). CONCLUSIONS There are multiple barriers that prevent the adequate assessment of the nutritional status of dialysis patients. Only after these resources are provided will it be possible to determine the impact of the nutrition guidelines on patient outcomes.

Abstract
The use of complementary and alternative medicine (CAM) in the United States is growing at a remarkable speed. Herbal products and dietary supplements are CAM therapies that have grown faster than any other CAM treatments. Little information is available about herbs and dietary supplement use in the stage 5 chronic kidney disease population. These products contain a myriad of pharmacologically active compounds that, when used by people with kidney disease, may be hazardous. Members of the renal dietitian listserv were queried about herbs and dietary supplements reportedly used by dialysis patients. Up-to-date information on the use, safety, efficacy, adverse effects, and recommended dosages in the nondialysis population are presented for 24 products. In the dialysis population, Noni juice should be avoided because of its high potassium content. In addition, bulk-forming laxatives such as flaxseed should be used with caution because of the need for increased fluid intake. Dialysis practitioners should include specific questions about herbs and dietary supplement use in medical and nutrition histories, and they should increase their knowledge about these products to advise patients appropriately. A list of reliable sources of information for the health care provider on herbs and dietary supplements is also presented.

Abstract
OBJECTIVE To compare the demographic and clinical characteristics and outcomes (morbidity) of 442 patients receiving maintenance hemodialysis who are at different levels of nutritional risk. DESIGN A retrospective, longitudinal, chart review. SETTING/SUBJECTS An urban, outpatient hemodialysis unit in New York City. Subjects were stratified according to their number of nutritional risk factors: zero to one=low risk, two to three=moderate risk, four to six=high risk. MAIN OUTCOME MEASURES Mean values for serum albumin <37 g/L, creatinine <884 micromol/L, total cholesterol <4.42 mmol/L, normalized protein nitrogen appearance <0.9 g/kg/day, weight change > -2.5 kg, and body mass index <24. Morbidity indicators were frequency and duration of hospitalizations. STATISTICAL ANALYSES Descriptive statistics, analysis of variance, and chi 2 analysis were used to summarize data and to analyze mean differences between the groups and differences in categorical variables, respectively. RESULTS Compared with the high-risk group, the majority of subjects in the low-risk group were younger, male, and did not have diabetes; fewer had two or more comorbidities. The high-risk group had 75% more hospitalizations and spent 195% more days in the hospital than the low-risk group. CONCLUSIONS Declining values of the nutritional risk factors and higher hospitalization rates were present in the high-risk group. Older subjects, those with diabetes, and those with two or more comorbidities comprised the majority of the high-risk group. More aggressive nutrition counseling and interventions may be needed for high-risk group members to determine if their risk for morbidity could be reduced.

Abstract
BACKGROUND The effect of standard or high dialysis dose and low or high dialysis flux on nutritional status was ascertained in 1846 maintenance hemodialysis patients enrolled in the HEMO Study. METHODS Serum albumin levels, equilibrated protein catabolic rate, and postdialysis weight were obtained monthly, while adjusted protein and energy intake, self-reported appetite assessment, upper arm circumference, and calf circumference were obtained yearly. To account for patient attrition due to death or transfer, three statistical models were used to test the effects of the study interventions on longitudinal changes in nutritional parameters. RESULTS During the first 3 years of follow-up, neither mean serum albumin levels, which declined by 0.21 g/dL, nor mean postdialysis weight, which declined by 2.7 kg, were significantly affected by either study intervention. Mean levels of all anthropometric measures declined during follow-up. For years 1, 2, and 3, the mean +/- SE declines in upper arm and calf circumferences were 0.35 +/- 0.16 cm (P= 0.031) and 0.31 +/- 0.13 (P= 0.015) cm less, respectively, in the high flux compared to the low flux group. Appetite scores and mean equilibrated protein catabolic rate also declined in all randomized groups; however, the average decline in equilibrated protein catabolic rate during years 1, 2, and 3 was 0.019 +/- 0.007 g/kg/day less in the high dose than the standard dose group (P= 0.007). There was no significant change in either mean energy or protein intake from diet records over time, and neither parameter was affected by the study interventions. CONCLUSION Although the dose and flux interventions may subtly influence certain nutritional parameters, neither intervention prevented deterioration in nutritional status over time.

Abstract
Medical nutrition therapy (MNT), nutrition education, and counseling are essential components for effective management of end-stage kidney disease (ESKD). Patients with ESKD have to alter their diets and to implement new eating behaviors, sometimes irrespective of ethnic and cultural food preferences because of their high content of specific nutrients. Ethnic and cultural factors influence dietary adherence. Therefore, assessing cultural issues surrounding food and food preferences may help improve dietary adherence. A large percentage of the ESKD population in the United States is black and Hispanic, with cultural food preferences that are particularly high in potassium, phosphorus, and sodium. This article provides an overview of the role of culture and ethnicity in food habits and dietary adherence, a list of cultural and ethnic foods that should be examined and incorporated in the development of an appropriate renal diet meal plan for black and Hispanic Americans with ESKD, and practical recommendations for cross-cultural nutrition counseling. If MNT is to be effective in the medical management of patients from different cultural and ethnic backgrounds, it must incorporate more traditional and customary foods in the renal diet meal plan.

Abstract
OBJECTIVE To evaluate differences between dietary energy intake (DEI), dietary protein intake (DPI), appetite, dietary patterns, and eating habits during dialysis treatment days (DD) and non-dialysis treatment days (NDD) in 1,901 adults receiving maintenance hemodialysis who were enrolled in the baseline phase of the National Institutes of Health-sponsored Hemodialysis (HEMO) study. DESIGN A cross-sectional analysis of participants at baseline (before randomization). SETTING Fifteen clinical centers across the United States. MEASUREMENTS DEI, DPI, and self-reported assessment of appetite, dietary patterns, and eating habits. RESULTS For the entire study cohort, total mean (+/- SD) DEI (1,566 +/- 636 kcal/day) and weight-adjusted DEI (23.2 +/- 9.5 kcal/kg/day) were significantly higher (P <.0001) on NDD than on DD (1,488 +/- 620 kcal/day and 22.2 +/- 9.6 kcal/kg/day), respectively. Similarly, DPI was significantly higher (P <.0001) on NDD (65.0 +/- 29.0 g/day and 0.96 +/- 0.43 g/kg/day) than on DD (60.2 +/- 26.5 g/day and 0.90 +/- 0.41 g/kg/day). On DD and NDD, the mean weight-adjusted DEI for the entire cohort was less than the HEMO study standard of care (SOC) of > or =28 kcal/kg/day, whereas on NDD, several subgroups reported dietary protein intakes that were closer to the study's SOC. These included men, patients under 50 years of age, nonblack participants, those without diabetes, those with a normal or mild Index of Co-Existing Disease score, and those on dialysis for more than 5 years. Protein and energy intakes declined with worsening self-reported appetites in both DD and NDD after adjusting for other subgroup effects. CONCLUSION Dietary energy and protein intakes of HEMO study participants were lower on DD than on NDD, and also lower than the SOC on both days, particularly with regard to energy intake. People receiving maintenance hemodialysis should be counseled to consume adequate amounts of energy and protein daily, especially on DD. Practitioners should monitor closely those patients who report poor appetite and should intervene appropriately.

Abstract
OBJECTIVE To evaluate associations between frequently used indicators for assessing nutritional status and health-related quality of life in hemodialysis patients after controlling for demographics, comorbidity, and dialysis dose. DESIGN Survey of 1,387 hemodialysis patients enrolled at baseline in the Hemodialysis (HEMO) Study. Nutritional status indicators included dietary energy intake, equilibrated normalized protein catabolic rate (enPCR), serum creatinine (SCr), serum albumin (SAlb), body mass index (BMI), calf circumference, and appetite. Health-related quality of life was measured by the Medical Outcomes Study Short Form-36 (MOS-SF-36) summary measures: the Physical Component Scale (PCS) and Mental Component Scale (MCS). SETTING Fifteen clinical sites throughout the United States providing in-center hemodialysis. RESULTS The mean PCS score was 36.1 +/- 10 SD, lower than normative data in healthy populations. PCS scores were lower among women, whites, and those with diabetes, severe comorbidities, and poor appetites. Appetite, dietary energy intake, SAlb, and SCr were strongly associated with PCS scores even after controlling for demographics and comorbidity. The sum of the parameter estimates for the effects of nutritional status on PCS was large, 7 points or more depending on the individual's nutritional status indicators. The mean MCS score was 49.7 +/- 10.1 SD, similar to scores in healthy populations, but lower among those with severe comorbidities, poor appetites, advanced age, and more years on dialysis. Appetite, age, and years on dialysis were significantly associated with MCS after controlling for other demographics and comorbidity. Dialysis dose did not significantly alter these relationships. CONCLUSION Easy-to-use indicators for assessing nutritional status (appetite, energy intake, SAlb, and SCr) together are strongly associated with health-related quality of life, even after controlling for comorbidities and dose of dialysis in hemodialysis patients, providing an additional reason for maximizing patients' nutritional status and health.

Abstract
OBJECTIVE To evaluate the dietary energy intakes (DEI) and dietary protein intakes (DPI) of older (> or = 65 years), middle-aged (50 to 64 years), and younger (< 50 years) maintenance hemodialysis patients enrolled in the Hemodialysis (HEMO) Study, and to describe the relationship between age, nutritional status, functional status, and comorbidity. DESIGN A cross-sectional analysis of the first 1,397 participants in baseline (before randomization) was performed. MAIN OUTCOME MEASURES DEI and DPI, serum albumin, creatinine, total cholesterol, normalized protein catabolic rate (nPCR), equilibrated nPCR (enPCR), functional status, and comorbidities. RESULTS Mean DEI, DPI, serum albumin, creatinine, nPCR, and enPCR were significantly lower in the older compared with the younger patients, despite similar doses of dialysis as measured by equilibrated Kt/V. Mean DEI, DPI, nPCR, and enPCR were not significantly different between the middle-aged and older patients, whereas albumin and creatinine were significantly lower in the older patients. Mean dry weight and percent of standard body weight in the younger and older patients were similar. In all groups, mean DEI was lower than both the HEMO study's standard of care (SOC) and the Kidney Disease Outcomes Quality Initiative (K/DOQI) nutrition recommendations, whereas mean DPI was lower than the SOC and K/DOQI recommendations only in the middle-aged and older patients. Middle-aged and older patients had higher cholesterol, lower functional status, and more comorbidities than the younger patients. CONCLUSION Middle-aged and older maintenance dialysis patients may be at greater risk for developing protein-energy malnutrition than their younger counterparts. Inadequate DEI and DPI reported in middle-aged and older patients were associated with lower levels of biomarkers of nutritional status, lower functional status, and higher comorbidities than in the younger patients.

Abstract
The nutritional status of the first 1,000 patients randomized into the Hemodialysis (HEMO) Study was analyzed at baseline when they received their typical dialysis dose (equilibrated Kt/V = 1.30 +/- 0.22) and dialysis membrane. This is the largest study to date of the nutritional status of chronic hemodialysis patients. The mean (+/- SD) values for these parameters included a serum albumin level of 3.65 +/- 0.38 g/dL, a dietary energy intake of 22.9 +/- 8.4 kcal/kg/day, a dietary protein intake of 0.93 +/- 0.36 g/kg/day, and a double pool normalized protein catabolic rate (enPCR) of 1.00 +/- 0.25 g/kg/day. The percentage of patients below HEMO Study nutritional standards of care included 29% of patients with a serum albumin level less than 3.5 g/dL, 76% of patients with a dietary energy intake less than 28 kcal/kg/day, 61% of patients with a dietary protein intake less than 1.0 g/kg/day, and 52% of patients with an enPCR of less than 1.0 g/kg/day. There was a strong correlation between dietary protein intake and dietary energy intake (r = 0.74, P < 0.0001). Significant correlations were also evident between serum albumin and double pool PCR and between dietary protein intake and double-pool PCR. Kt/V and membrane flux were not predictive of baseline dietary protein intake, dietary energy intake, or serum albumin level. Thus, a majority of patients in the HEMO Study had protein and energy intake levels and enPCR levels that were below National Kidney Foundation Kidney Dialysis Outcome Quality Improvement (NKF-K/DOQI) guidelines.

Abstract
OBJECTIVE To determine the safety and efficacy of moderate doses of megestrol acetate (>/=320 mg/day) in a patient on hemodialysis. DESIGN Case study. SETTING Chronic hemodialysis facility and body composition unit in New York City. MAIN OUTCOME MEASURES Body weight, body composition, dietary energy and protein intake, appetite assessment, serum albumin, prealbumin, serum transferrin, and quality of life. RESULTS The patient received megestrol acetate for 24 weeks and gained little body weight. However, his fat mass increased by 7.5 kg (163%), and fat-free mass decreased by 6.8 kg (10.6%) from baseline measurements. The proportional content of total body water, extracellular water, intracellular water, body cell mass in fat-free mass, and average cell K+ concentration were maintained within normal ranges. Serum albumin was maintained, serum transferrin increased, prealbumin decreased, dietary energy and protein intakes increased, and reported appetite improved. CONCLUSIONS Moderate doses of megestrol acetate may be an effective therapeutic agent in reversing poor appetite, increasing dietary energy and protein intakes, and improving nutritional status in some patients receiving maintenance hemodialysis. However, these changes were at the expense of altering body composition components. Further research that includes measures of body composition, nutritional status, appetite assessment, and quality of life are needed to determine the safety and effectiveness of moderate or high doses of megestrol acetate in a large number of hemodialysis patients.

Abstract
OBJECTIVE Describe the nutrition program (assessments and interventions) and the participants' baseline nutritional characteristics in the Hemodialysis Pilot Study. DESIGN Cross sectional survey in which hemodialysis patients were examined during 10 weeks of baseline (BL), before randomization study interventions (dose and flux). SETTING Four hemodialysis centers (eight dialysis units in total). PATIENTS Twenty-nine male (mean age, 63 years; range, 34 to 75) and 20 female (mean age, 61 years; range, 29 to 73) hemodialysis patients. INTERVENTIONS None during BL. MAIN OUTCOME MEASURES Feasibility of implementing the proposed nutrition program before conducting the full-scale trial, and description of baseline characteristics related to nutrition. RESULTS A nutrition program was developed to assess nutritional status during BL and follow-up periods and to intervene in patients with weight loss or decreasing serum albumin. Methods for collecting biochemical, dietary and anthropometric data were implemented at four clinical centers. At baseline, mean protein intake estimated by single pool normalized protein catabolic rate was 0.95 +/- 0.21 gm/kg adjusted body weight (ABW) (n = 42) and by diet record assisted recalls (n = 47) 0.94 +/- 0.36 gm/kg ABW/d, respectively. Mean energy intake was 22.8 +/- 8 kcal/kg ABW/day (n = 39). Mean serum albumin concentration using the bromcresol green method was 3.8 +/- 0.4 gm/dL (n = 40). Mean body mass index was within the normal limits of 19-27 kg/m2. Mean skinfold thicknesses in females, but not males, were shifted toward the lower end of usual distributions for healthy individuals. CONCLUSIONS The goal of designing, developing, and implementing the diet and nutrition component, and related data collection for the HEMO pilot study was accomplished at four separate clinical centers. Baseline mean protein and energy intake were low, suggesting that continuing dietary surveillance is needed. The ongoing full-scale HEMO study will provide the first prospective analysis of dietary intake, nutritional status, and outcome in maintenance hemodialysis patients as a function of dialysis dose and membrane flux.

Intradialytic parenteral nutrition: a practical approach. ANNA JOURNAL 1993; 20:671-7. [PMID: 8267411] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Subscribe] [Scholar Register] [Indexed: 01/29/2023]
Abstract
Intradialytic parenteral nutrition (IDPN) therapy is becoming more prevalent in the malnourished patient undergoing maintenance hemodialysis. This is of particular concern to the nephrology nurse in that additional time is required to administer the solution, monitor the patient, and document the process. The IDPN monitoring flowsheet described in this article was developed to promote continuity of care from treatment to treatment, especially during initiation of IDPN, and to assist the nephrology nurse in administering and monitoring the therapy.
