Current practice in nutrition after allogeneic hematopoietic stem cell transplantation - Results from a survey among hematopoietic stem cell transplant centers.

BACKGROUND: Allogeneic hematopoietic stem cell transplantation (alloHSCT) is frequently associated with impaired oral intake and malnutrition, which potentially increases morbidity and mortality. Therefore, nutrition is one of the major challenges in the post-transplant period. METHODS: To document the current clinical approach in nutritional treatment, we designed a questionnaire concerning the current practice in nutrition after alloHSCT and distributed it to German speaking centers performing alloHSCT in Germany, Austria and Switzerland between November 2018 and March 2020. Twenty-eight (39%) of 72 contacted centers completed the survey, 23 from Germany, two from Austria and three from Switzerland, representing 50% of alloHSCT activity within the participating countries in 2018. RESULTS: All centers reported having nutritional guidelines for patients undergoing alloHSCT, whereby 86% (n = 24) provided a low-microbial diet during the neutropenic phase. The criteria to start parenteral nutrition (PN) directly after alloHSCT seemed to be consistent, 75% (n = 21) of the corresponding centers started PN if the oral nutritional intake or the bodyweight dropped below a certain limit. In the setting of intestinal graft-versus-host disease (GvHD) the current practice appeared to be more heterogenous. About 64% (n = 18) of the centers followed a special diet, added food stepwise modulated by GvHD symptoms, while only four centers regularly stopped oral intake completely (intestinal GvHD grade >1). Half of the centers (54%, n = 15) applied a lactose-free diet, followed by 43% (n = 12) which provided fat- and 18% (n = 5) gluten-free food in patients with intestinal GvHD. Supplementation of micronutrients in acute intestinal GvHD patients was performed by 54% (n = 15) of the centers, whereas vitamin D (89%, n = 25) and vitamin B12 (68%, n = 19) was added regularly independently of the presence of GvHD. Only 5 (18%) participating centers ever observed a food-associated infection during hospitalization, whereas food-associated infections were reported to occur more often in the outpatient setting (64%, n = 18). CONCLUSION: The survey documented a general consensus about the need for nutritional guidelines for patients undergoing alloHSCT. However, the nutritional treatment in clinical practice (i.e. lactose-, gluten- or fat-free in intestinal GvHD) as well as the use of food supplements was very heterogeneous. In line with current general recommendations the centers seemed to focus on safe food handling practice rather than providing a strict neutropenic diet. More high-quality data are required to provide evidence-based nutrition to patients during and after alloHSCT.

Omega-3 fatty acid-containing parenteral nutrition in ICU patients: systematic review with meta-analysis and cost-effectiveness analysis.

BACKGROUND: Omega-3 (ω-3) fatty acid (FA)-containing parenteral nutrition (PN) is associated with significant improvements in patient outcomes compared with standard PN regimens without ω-3 FA lipid emulsions. Here, we evaluate the impact of ω-3 FA-containing PN versus standard PN on clinical outcomes and costs in adult intensive care unit (ICU) patients using a meta-analysis and subsequent cost-effectiveness analysis from the perspective of a hospital operating in five European countries (France, Germany, Italy, Spain, UK) and the US. METHODS: We present a pharmacoeconomic simulation based on a systematic literature review with meta-analysis. Clinical outcomes and costs comparing ω-3 FA-containing PN with standard PN were evaluated in adult ICU patients eligible to receive PN covering at least 70% of their total energy requirements and in the subgroup of critically ill ICU patients (mean ICU stay > 48 h). The meta-analysis with the co-primary outcomes of infection rate and mortality rate was based on randomized controlled trial data retrieved via a systematic literature review; resulting efficacy data were subsequently employed in country-specific cost-effectiveness analyses. RESULTS: In adult ICU patients, ω-3 FA-containing PN versus standard PN was associated with significant reductions in the relative risk (RR) of infection (RR 0.62; 95% CI 0.45, 0.86; p = 0.004), hospital length of stay (HLOS) (- 3.05 days; 95% CI - 5.03, - 1.07; p = 0.003) and ICU length of stay (LOS) (- 1.89 days; 95% CI - 3.33, - 0.45; p = 0.01). In critically ill ICU patients, ω-3 FA-containing PN was associated with similar reductions in infection rates (RR 0.65; 95% CI 0.46, 0.94; p = 0.02), HLOS (- 3.98 days; 95% CI - 6.90, - 1.06; p = 0.008) and ICU LOS (- 2.14 days; 95% CI - 3.89, - 0.40; p = 0.02). Overall hospital episode costs were reduced in all six countries using ω-3 FA-containing PN compared to standard PN, ranging from €-3156 ± 1404 in Spain to €-9586 ± 4157 in the US. CONCLUSION: These analyses demonstrate that ω-3 FA-containing PN is associated with statistically and clinically significant improvement in patient outcomes. Its use is also predicted to yield cost savings compared to standard PN, rendering ω-3 FA-containing PN an attractive cost-saving alternative across different health care systems.

High Frequency of Non-Compliance with Quality Indicators of Enteral and Parenteral Nutritional Therapy in Hospitalized Patients.

Quality indicators in nutritional therapy (QINT) are measures of the effectiveness and quality of nutrition support. The purpose of this study was to evaluate the frequency of the QINT adequacy of Enteral Nutritional Therapy (EN) and/or Parenteral (PN) in hospitalized patients and identify the best indicators according to health professionals. A prospective study was performed, including data from patients aged 18 years or over admitted to clinical or surgical wards. The patients who had received EN and/or PN were followed from the first day of nutritional prescription until discharge. Twelve indicators were calculated, as recommended by the literature. Regarding professional opinion, the QINT adequacy was evaluated by observing its utility, simplicity, objectivity, and cost. Of the 727 hospitalized patients, 101 were on EN and/or PN. Regarding the 12 QINT evaluated, only 25% (3) achieved the goals: involuntary withdrawal of enteral feeding tube (0.01%); feeding tube occlusion or withdrawal per occlusion (0%); the measurement of energy and protein requirements (92%). A high frequency of non-compliance (75% of QINT) was observed in clinical and surgical patients on EN and/or PN. With knowledge of the six best indicators chosen by health professionals in this service, it will be possible to elaborate protocols according to the real-life situation in the institution.

Biomarkers in critical care nutrition.

The goal of nutrition support is to provide the substrates required to match the bioenergetic needs of the patient and promote the net synthesis of macromolecules required for the preservation of lean mass, organ function, and immunity. Contemporary observational studies have exposed the pervasive undernutrition of critically ill patients and its association with adverse clinical outcomes. The intuitive hypothesis is that optimization of nutrition delivery should improve ICU clinical outcomes. It is therefore surprising that multiple large randomized controlled trials have failed to demonstrate the clinical benefit of restoring or maximizing nutrient intake. This may be in part due to the absence of biological markers that identify patients who are most likely to benefit from nutrition interventions and that monitor the effects of nutrition support. Here, we discuss the need for practical risk stratification tools in critical care nutrition, a proposed rationale for targeted biomarker development, and potential approaches that can be adopted for biomarker identification and validation in the field.

ASPEN Lipid Injectable Emulsion Safety Recommendations, Part 1: Background and Adult Considerations.

Lipid injectable emulsions (ILEs) are complex pharmaceutical formulations used as a source of energy and essential fatty acids in parenteral nutrition. Issues associated with ILE use are distinctly different from oral fat and arise from emulsion stability, dose, and infusion tolerance. Since 1975, soybean oil has been the consistent source oil used in ILE formulations in the US. Partly because of safety concerns with the soybean-based ILE and frequent and long-standing problems with product inventory shortages, new ILE products have become available. Gaps in ILE best practices create a risk for ILE safety errors in prescribing, compounding, and administration of these products. This paper provides information on appropriate indications, dosing, and methods to avoid potential errors with ILE products in the US. This paper (Part 1) will focus on ILE background, information, and recommendations for adult patients, whereas Part 2 of this series will focus on neonatal and pediatric patient-specific information.

Nutrition therapy in critical illness: a review of the literature for clinicians.

Nutrition therapy during critical illness has been a focus of recent research, with a rapid increase in publications accompanied by two updated international clinical guidelines. However, the translation of evidence into practice is challenging due to the continually evolving, often conflicting trial findings and guideline recommendations. This narrative review aims to provide a comprehensive synthesis and interpretation of the adult critical care nutrition literature, with a particular focus on continuing practice gaps and areas with new data, to assist clinicians in making practical, yet evidence-based decisions regarding nutrition management during the different stages of critical illness.

Brazilian Nutritional Consensus in Hematopoietic Stem Cell Transplantation: Adults.

The nutritional status of patients submitted to hematopoietic stem cell transplant is considered an independent risk factor, which may influence on quality of life and tolerance to the proposed treatment. The impairment of nutritional status during hematopoietic stem cell transplant occurs mainly due to the adverse effects resulting from conditioning to which the patient is subjected. Therefore, adequate nutritional evaluation and follow-up during hematopoietic stem cell transplant are essential. To emphasize the importance of nutritional status and body composition during treatment, as well as the main characteristics related to the nutritional assessment of the patient, the Brazilian Consensus on Nutrition in Hematopoietic Stem Cell Transplant: Adults was prepared, aiming to standardize and update Nutritional Therapy in this area. Dietitians, nutrition physicians and hematologists from 15 Brazilian centers thar are references in hematopoietic stem cell transplant took part.

The Influence of Donor Milk Supplementation on Duration of Parenteral Nutrition in Preterm Infants.

BACKGROUND: Data are limited on the association between the use of donor human milk and improvements in feeding tolerance. OBJECTIVE: To determine the influence of the duration of parenteral nutrition on the growth and morbidity of the breastfed newborn when using donated human milk in the absence of mother's own milk. METHODS: We conducted a retrospective study before and after the intervention that compared two groups of newborns (N = 284; each group n = 142). We used a convenience sample of all newborns ≤32 weeks gestation consecutively admitted in a single unit before (Group 1 between December 2012 and May 2014) or after (Group 2 between October 2014 and December 2016) the availability of donor human milk. In Group 2, donor human milk was administered at least 3 to 4 weeks or until the baby weighed 1,500 g. Weight was recorded daily and length and head circumference weekly. Parenteral nutrition was continued until enteral feeding volume reached 120 ml/kg/day. Additional variables measured were the number of days with a central venous catheter, age that the enteral feeding volume reached 150 ml/kg/day, and duration of stay. RESULTS: The duration of parenteral feeding was the same before and after: 12 (8.23) and 11 (7.19) days (p = .822). The z scores for weight and height of newborns was lower in Group 2 = -1.8 (1.0) and -2.3 (1.1) and Group 1 = -1.2 (1.1) (p < .001) and -1.8 (1.4) (p = .005). CONCLUSION: We did not find an association between the administration of donor human milk as a supplement to mother's own milk and reduced number of days of parenteral nutrition.

[Iron supplementation in iron deficiency anaemia]. / Suppletie van ijzer bij ijzergebreksanemie.

Iron deficiency anaemia is a common problem. The majority of patients are treated with oral iron supplements. The current recommended dosage for oral supplementation of 200 mg ferrous fumarate 3x per day however, is based on a single small study of poor quality. There is no consensus concerning parenteral dosing. In recent years, new insights have been gained regarding both the dosage of oral supplementation and the indication for parenteral supplementation. Oral therapy is preferred. In principle, 100 mg ferrous fumarate once a day is sufficient for the treatment of symptom-free patients with anaemia. In cases of severe anaemia, or in patients with symptoms, 200 mg/day should be prescribed. If side effects appear, it can be dosed every other day. Where oral therapy does not show effectiveness, the anaemia is severe, or rapid increase of haemoglobin is indicated, parenteral supplementation should be chosen. Parenteral supplementation is more effective than oral supplementation in specific conditions, such as dialysis-dependent renal insufficiency, heart failure or active IBD.

Clinical Nutrition in Critical Care Medicine - Guideline of the German Society for Nutritional Medicine (DGEM).

PURPOSE: Enteral and parenteral nutrition of adult critically ill patients varies in terms of the route of nutrient delivery, the amount and composition of macro- and micronutrients, and the choice of specific, immune-modulating substrates. Variations of clinical nutrition may affect clinical outcomes. The present guideline provides clinicians with updated consensus-based recommendations for clinical nutrition in adult critically ill patients who suffer from at least one acute organ dysfunction requiring specific drug therapy and/or a mechanical support device (e.g., mechanical ventilation) to maintain organ function. METHODS: The former guidelines of the German Society for Nutritional Medicine (DGEM) were updated according to the current instructions of the Association of the Scientific Medical Societies in Germany (AWMF) valid for a S2k-guideline. According to the S2k-guideline classification, no systematic review of the available evidence was required to make recommendations, which, therefore, do not state evidence- or recommendation grades. Nevertheless, we considered and commented the evidence from randomized-controlled trials, meta-analyses and observational studies with adequate sample size and high methodological quality (until May 2018) as well as from currently valid guidelines of other societies. The liability of each recommendation was described linguistically. Each recommendation was finally validated and consented through a Delphi process. RESULTS: In the introduction the guideline describes a) the pathophysiological consequences of critical illness possibly affecting metabolism and nutrition of critically ill patients, b) potential definitions for different disease phases during the course of illness, and c) methodological shortcomings of clinical trials on nutrition. Then, we make 69 consented recommendations for essential, practice-relevant elements of clinical nutrition in critically ill patients. Among others, recommendations include the assessment of nutrition status, the indication for clinical nutrition, the timing and route of nutrient delivery, and the amount and composition of substrates (macro- and micronutrients); furthermore, we discuss distinctive aspects of nutrition therapy in obese critically ill patients and those treated with extracorporeal support devices. CONCLUSION: The current guideline provides clinicians with up-to-date recommendations for enteral and parenteral nutrition of adult critically ill patients who suffer from at least one acute organ dysfunction requiring specific drug therapy and/or a mechanical support device (e.g., mechanical ventilation) to maintain organ function. The period of validity of the guideline is approximately fixed at five years (2018-2023).

AGREEing on Guidelines for Nutrition Management of Adult Severe Burn Patients.

BACKGROUND: Severe burns are associated with a plethora of profound metabolic, immunologic, and physiologic responses, demanding prompt and adequate management. The objective of the present study was to review, compare, and critically appraise medical nutrition therapy guidelines for adult patients with severe burns, and produce salient points for the future update of relevant guidelines. METHODS: A total of 8 clinical practice guidelines developed by the American Burn Association (ABA), the European Burn Association (EBA), the European Society for Parenteral and Enteral Nutrition (ESPEN), the Midlands National Health Service, the Society for Critical Care Medicine (SCCM)/American Society for Parenteral and Enteral Nutrition (ASPEN), the Spanish Society of Intensive Care Medicine and Coronary Units and Spanish Society of Parenteral and Enteral Nutrition, the Indian Association for Parenteral and Enteral Nutrition (IAPEN), and the International Society for Burn Injury regarding medical nutrition therapy in burn patients was independently reviewed by a team of 4 multidisciplinary researchers using the Appraisal of Guidelines for Research & Evaluation (AGREE II) instrument. RESULTS: From the appraised guidelines, the SCCM/ASPEN guidelines received the greatest scoring in the majority of AGREE domains compared with ABA, EBA, and IAPEN, which obtained the lowest scores. On the other hand, the ESPEN guidelines provided the majority of information concerning nutrition support and medical nutrition therapy. CONCLUSION: Our study identified gaps in most nutrition guidelines and emphasized methodologic issues that could improve the quality of future guidelines concerning nutrition support among adult severe burn patients.

Chinese guidelines for the assessment and provision of nutrition support therapy in critically ill children.

BACKGROUND: This document represents the first evidence-based guidelines to describe best practices in nutrition therapy in critically ill children (> 1 month and < 18 years), who are expected to require a length of stay more than 2 or 3 days in a Pediatric Intensive Care Unit admitting medical patients domain. METHODS: A total of 25,673 articles were scanned for relevance. After careful review, 88 studies appeared to answer the pre-identified questions for the guidelines. We used the grading of recommendations, assessment, development and evaluation criteria to adjust the evidence grade based on the quality of design and execution of each study. RESULTS: The guidelines emphasise the importance of nutritional assessment, particularly the detection of malnourished patients. Indirect calorimetry (IC) is recommended to estimate energy expenditure and there is a creative value in energy expenditure, 50 kcal/kg/day for children aged 1-8 years during acute phase if IC is unfeasible. Enteral nutrition (EN) and early enteral nutrition remain the preferred routes for nutrient delivery. A minimum protein intake of 1.5 g/kg/day is suggested for this patient population. The role of supplemental parenteral nutrition (PN) has been highlighted in patients with low nutritional risk, and a delayed approach appears to be beneficial in this group of patients. Immune-enhancing cannot be currently recommended neither in EN nor PN. CONCLUSION: Overall, the pediatric critically ill population is heterogeneous, and an individualized nutrition support with the aim of improving clinical outcomes is necessary and important.

Drug Shortages: Effect on Parenteral Nutrition Therapy.

Drug shortages continue to be a threat to the health and welfare of numerous patients in the United States. For patients who depend on parenteral nutrition (PN) for survival, these shortages pose an even greater threat. Almost 75% of active drug shortages are sterile injectables, which includes PN components. Providing PN therapy is particularly challenging for clinicians because this is a complex medication and may contain 40 or more individual ingredients, of which multiple components may simultaneously be in limited supply. The availability of PN components must be considered during every step of the PN use process from ordering the PN prescription to administering this therapy to a patient. Alterations to a standardized process can lead to medication errors that can adversely affect patient outcomes and consume healthcare resources.

Nutrition Therapy in Sepsis.

Sepsis is characterized by early massive catabolism, lean body mass (LBM) loss, and escalating hypermetabolism persisting for months to years. Early enteral nutrition should attempt to correct micronutrient/vitamin deficiencies, deliver adequate protein and moderated nonprotein calories, as well-nourished patients can generate reasonable endogenous energy. After resuscitation, increasing protein/calories are needed to attenuate LBM loss and promote recovery. Malnutrition screening is essential, and parenteral nutrition can be safely added when enteral nutrition is failing based on preillness malnutrition. Following discharge from intensive care unit, significantly increased protein/calorie delivery is required for months to years to facilitate functional and LBM recovery.

Guidelines for the Provision and Assessment of Nutrition Support Therapy in the Pediatric Critically Ill Patient: Society of Critical Care Medicine and American Society for Parenteral and Enteral Nutrition.

This document represents the first collaboration between 2 organizations-the American Society for Parenteral and Enteral Nutrition and the Society of Critical Care Medicine-to describe best practices in nutrition therapy in critically ill children. The target of these guidelines is intended to be the pediatric critically ill patient (>1 month and <18 years) expected to require a length of stay >2-3 days in a PICU admitting medical, surgical, and cardiac patients. In total, 2032 citations were scanned for relevance. The PubMed/MEDLINE search resulted in 960 citations for clinical trials and 925 citations for cohort studies. The EMBASE search for clinical trials culled 1661 citations. In total, the search for clinical trials yielded 1107 citations, whereas the cohort search yielded 925. After careful review, 16 randomized controlled trials and 37 cohort studies appeared to answer 1 of the 8 preidentified question groups for this guideline. We used the GRADE criteria (Grading of Recommendations, Assessment, Development, and Evaluation) to adjust the evidence grade based on assessment of the quality of study design and execution. These guidelines are not intended for neonates or adult patients. The guidelines reiterate the importance of nutrition assessment-particularly, the detection of malnourished patients who are most vulnerable and therefore may benefit from timely intervention. There is a need for renewed focus on accurate estimation of energy needs and attention to optimizing protein intake. Indirect calorimetry, where feasible, and cautious use of estimating equations and increased surveillance for unintended caloric underfeeding and overfeeding are recommended. Optimal protein intake and its correlation with clinical outcomes are areas of great interest. The optimal route and timing of nutrient delivery are areas of intense debate and investigations. Enteral nutrition remains the preferred route for nutrient delivery. Several strategies to optimize enteral nutrition during critical illness have emerged. The role of supplemental parenteral nutrition has been highlighted, and a delayed approach appears to be beneficial. Immunonutrition cannot be currently recommended. Overall, the pediatric critical care population is heterogeneous, and a nuanced approach to individualizing nutrition support with the aim of improving clinical outcomes is necessary.

PROTOCOL NUTRITION THERAPY OF CRITICALLY ILL CHILDREN.

The Protocol isn't seen as directive. The goal of the Protocol is to define theframes ofdiagnostic criteria and therapeutic action, within which a doctor working in an intensive therapy children have freedom of choice. The Protocol takes into account that the critical and postagressive states are characterized by the features of malnutrition, particularly manifested in the period of intensive growth (first life year). The Protocol submitted by: contraindications to artificial nutricion in any form; indications for parenteral nutrition; components ofparenteral nutrition; calculation of water and energy needs; calculation of substrate requirements; the system of "two in one" and "three in one "; monitoring the effectiveness ofparenteral nutrition; the use of adjuvants and active additives to artificial nutrition, indications for early enteral nutrition, time of the beginning of enteral nutricion and tolerance to it: trial feeding; trophic nutricion; the technique ofprobe feeding; selection offormulas for enteral nutrition; monitoring the effectiveness of enteral nutrition. The Protocol does not discuss the issues of planned nutritional preparation for surgery, nutritional support in chronic malabsorption, sipping.

Quality indicators for enteral and parenteral nutrition therapy: application in critically ill patients "at nutritional risk".

INTRODUCTION: Quality Indicators for Nutritional Therapy (QINT) allow a practical assessment of nutritional therapy (NT) quality. OBJECTIVE: To apply and monitor QINT for critically ill patients at nutritional risk. METHODS: Cross sectional study including critically ill patients > 18 years old, at nutritional risk, on exclusive enteral (ENT) or parenteral nutritional therapy (PNT) for > 72 hours. After three consecutive years, 9 QINT were applied and monitored. Statistical analysis was performed with SPSS version 17.0. RESULTS: A total of 145 patients were included, 93 patients were receiving ENT, among then 65% were male and the mean age was 55.7 years (± 17.4); 52 patients were receiving PNT, 67% were male and the mean age was 58.1 years (± 17.4). All patients (ENT and PNT) were nutritionally screened at admission and their energy and protein needs were individually estimated. Only ENT was early initiated, more than 70% of the prescribed ENT volume was infused and there was a reduced withdrawal of enteral feeding tube. The frequency of diarrhea episodes and digestive fasting were not adequate in ENT patients. The proper supply of energy was contemplated only for PNT patients and there was an expressive rate of oral intake recovery in ENT patients. CONCLUSION: After three years of research, the percentage of QINT adequacy varied between 55%-77% for ENT and 60%-80% for PNT. The results were only made possible by the efforts of a multidisciplinary team and the continuous re-evaluation of the procedures in order to maintain the nutritional assistance for patients at nutritional risk.

[Nutritional management for patients hospitalized during allogeneic stem cell transplantation: Guidelines from the Francophone Society of Bone Marrow Transplantation and Cellular Therapy (SFGM-TC)]. / Prise en charge nutritionnelle des patients hospitalisés pour allogreffe de CSH : recommandations de la Société francophone de greffe de moelle et de thérapie cellulaire (SFGM-TC).

Allogeneic haematopoietic stem-cell transplantation is usually applied with success for patients with diseases involving bone marrow and associated with frequent and severe malnutrition. Denutrition is an independent survival factor and contribute to transplant-related mortality. Due to the heaviness of the treatment, this event is frequent. Before allogeneic transplantation, the nutritional statute should be evaluated. The adult or pediatric patient's evaluation modalities and nutritional needs are detailed in this paper. The administration modalities (enteral or parenteral) with doses are specifically precise. We also explain why the enteral nutritional support may remain the best option comparing to parenteral option.

Parenteral trace element provision: recent clinical research and practical conclusions.

The aim of this systematic review (PubMed, www.ncbi.nlm.nih.gov/pubmed and Cochrane, www.cochrane.org; last entry 31 December 2014) was to present data from recent clinical studies investigating parenteral trace element provision in adult patients and to draw conclusions for clinical practice. Important physiological functions in human metabolism are known for nine trace elements: selenium, zinc, copper, manganese, chromium, iron, molybdenum, iodine and fluoride. Lack of, or an insufficient supply of, these trace elements in nutrition therapy over a prolonged period is associated with trace element deprivation, which may lead to a deterioration of existing clinical symptoms and/or the development of characteristic malnutrition syndromes. Therefore, all parenteral nutrition prescriptions should include a daily dose of trace elements. To avoid trace element deprivation or imbalances, physiological doses are recommended.
