The role of lipid emulsions containing omega-3 fatty acids for medical and surgical critical care patients.

In critical illness the regulation of inflammation and oxidative stress can improve patient outcomes, and thus omega-3 polyunsaturated fatty acids (PUFAs) have been used as part of parenteral nutrition (PN) owing to their potential anti-inflammatory effects. The international lipids in PN Summit, encompassed discussions and the production of consensus guidelines concerning PN intravenous lipid emulsion (ILE) use in critical care. The Lipid Summit participants agreed that the inclusion of fish oil in ILEs is associated with meaningful clinical benefits without signals of harm, based on a strong biological rationale and current clinical evidence. Decisions concerning ILE choice should be made based on current evidence, thus addressing clinical requirements for guidance, particularly as further definitive evidence seems unlikely to occur. In addition, a future of individualized ICU care is envisioned, yielding better clinical outcomes. This approach will require the greater use of intelligent study designs incorporating the use of biomarkers of omega-3 derivatives, inflammatory-resolving processes, and/or muscle protein breakdown.

The "Guidelines for parenteral nutrition in preterm infants: the American Society for parenteral and enteral nutrition" were developed by the American Society for Parenteral and Enteral Nutrition and published in the Journal of Parenteral and Enteral Nutrition in September 2023. The guidelines provide recommendations on 12 key clinical questions regarding parenteral nutrition (PN) for preterm infants. In comparison to similar guidelines, this set offers more detailed perspectives on PN for preterm infants. It presents evidence-based recommendations for the commencement time, nutrient dosage, and composition of PN, considering primary outcomes such as growth and development, as well as secondary outcomes like sepsis, retinopathy of prematurity, parenteral nutrition-related liver disease, and jaundice. This article aims to interpret the guidelines to provide a reference for colleagues in the field.

Expert consensus statements and summary of proceedings from the International Safety and Quality of Parenteral Nutrition Summit.

PURPOSE: The International Safety and Quality of Parenteral Nutrition (PN) Summit consisted of presentations, discussions, and formulation of consensus statements. The purpose here is to briefly summarize the summit and to present the consensus statements. SUMMARY: There was a high degree of consensus, with all statements approved by all authors/summit experts. These consensus statements should be regarded not as formal guidelines but rather as best-practice guidance intended to complement national and international nutrition society evidence-based guidelines and position statements. This article also summarizes key discussion topics from the summit, encompassing up-to-date knowledge and practical guidance concerning PN safety and quality in various countries and clinical settings, focusing on adult patients. Clear geographical differences exist between practices in Europe and the United States, and different approaches to improve the safety, quality, and cost-effectiveness of PN vary, particularly with regard to the delivery systems used. Discussion between experts allowed for an exchange of practical experience in optimizing PN use processes, opportunities for standardization, use of electronic systems, potential improvements in PN formulations, better management during PN component shortages, and practical guidance to address patients' needs, particularly during long-term/home PN. CONCLUSION: The consensus statements are the collective opinion of the panel members and form best-practice guidance. The authors intend that this guidance may help to improve the safety and quality of PN in a variety of settings by bridging the gap between published guideline recommendations and common practical issues.

Safe and efficient practice of parenteral nutrition in neonates and children aged 0-18 years - The role of licensed multi-chamber bags.

Parenteral nutrition (PN) is recognized as a complex high-risk therapy. Its practice is highly variable and frequently suboptimal in pediatric patients. Optimizing care requires evidence, consensus-based guidelines, audits of practice, and standardized strategies. Several pediatric scientific organizations, expert panels, and authorities have recently recommended that standardized PN should generally be used over individualized PN in the majority of pediatric patients including very low birth weight premature infants. In addition, PN admixtures produced and validated by a suitably qualified institution are recommended over locally produced PN. Licensed multi chamber bags are standardized PN bags that comply with Good Manufacturing Practice and high-quality standards for the finished product in the frame of their full manufacturing license. The purpose of this article is to review the practical aspects of PN and the evidence for using such multi-chamber bags in pediatric patients. It highlights the safety characteristics and the limitations of the different PN practices and provides some guidance for ensuring safe and efficient therapy in pediatric patients.

Parenteral nutrition in the hospital setting/short-term parenteral nutrition.

PURPOSE: This article is based on presentations and discussions held at the International Safety and Quality of Parenteral Nutrition (PN) Summit concerning the acute care setting. Some European practices presented in this article do not conform with USP general chapter <797> requirements. Nevertheless, the purpose is to cover the challenges experienced in delivering high-quality PN within hospitals in the United States and Europe, in order to share best practices and experiences more widely. SUMMARY: Core issues regarding the PN process within an acute care setting are largely the same everywhere: There are ongoing pressures for greater efficiency, optimization, and also concurrent commitments to make PN safer for patients. Within Europe, in recent years, the use of market-authorized multi-chamber bags (MCBs) has increased greatly, mainly for safety, cost-effectiveness, and efficiency purposes. However, in the US, hospitals with low PN volumes may face particular challenges, as automated compounding equipment is often unaffordable in this setting and the variety of available MCBs is limited. This can result in the need to operate several PN systems in parallel, adding to the complexity of the PN use process. Ongoing PN quality and safety initiatives from US institutions with various PN volumes are presented. In the future, the availability of a greater selection of MCBs in the US may increase, leading to a reduction in dependence on compounded PN, as has been seen in many European countries. CONCLUSION: The examples presented may encourage improvements in the safety and quality of PN within the acute care setting worldwide.

Safety and quality of parenteral nutrition: Areas for improvement and future perspectives.

PURPOSE: This article is based on presentations and discussions held at the International Safety and Quality of Parenteral Nutrition (PN) Summit (held November 8-10, 2021, at Charleston, SC, and Bad Homburg, Germany) and aims to raise awareness concerning unresolved issues associated with the PN process and potential future directions, including a greater emphasis on patients' perspectives and the role of patient support. SUMMARY: Ensuring that every patient in need receives adequate PN support remains challenging. It is important to have a standardized approach to identify nutritional risk and requirements using validated nutritional screening and assessment tools. Gaps between optimal and actual clinical practices need to be identified and closed, and responsibilities in the nutrition support team clarified. Use of modern technology opens up opportunities to decrease workloads or liberate resources, allowing a more personalized care approach. Patient-centered care has gained in importance and is an emerging topic within clinical nutrition, in part because patients often have different priorities and concerns than healthcare professionals. Regular assessment of health-related quality of life, functional outcomes, and/or overall patient well-being should all be performed for PN patients. This will generate patient-centric data, which should be integrated into care plans. Finally, communication and patient education are prerequisites for patients' commitment to health and for fostering adherence to PN regimes. CONCLUSION: Moving closer to optimal nutritional care requires input from healthcare professionals and patients. Patient-centered care and greater emphasis on patient perspectives and priorities within clinical nutrition are essential to help further improve clinical nutrition.

Parenteral nutrition consensus report from KEPAN.

OBJECTIVES: Medical nutrition therapy is one of the core components of patient management, although its implication is still limited in Daily practice globally. Clinicians are in need of guidance that will ease the application of medical nutrition therapy. The pre- and post-graduate curriculum for medical nutrition therapy is limited in most regions, worldwide. A report that is short, clear, and having clear-cut recommendations that will guide the primary healthcare professionals in indications, choice, practical application, follow-up, and stopping parenteral nutrition (PN) would facilitate the application and success of medical nutrition therapy. KEPAN is the Clinical Enteral and Parenteral Nutrition Society of Turkey and is an active member of the European Society for Clinical Nutrition and Metabolism (ESPEN). METHOD: In this study, we present the KEPAN PN consensus report on optimal PN use in medical nutrition therapy as outlined by the works of academicians experienced in the clinical application of PN (nine working group academicians and 10 expert group academicians). RESULTS: This report provides 22 clear-cut recommendations in a question-answer format. CONCLUSIONS: We believe that this report could have a significant impact on the optimum use of PN in the context of medical nutrition therapy when clinicians manage everyday patients.

Multidisciplinary evidence-based tools for improving consistency of care and neonatal nutrition.

BACKGROUND: Extrauterine growth restriction from inadequate nutrition remains a significant morbidity in very low birth weight infants. Participants in the California Perinatal Quality Care Collaborative Quality Improvement Collaborative, Grow, Babies, Grow! developed or refined tools to improve nutrition and reduce practice variation. METHOD: Five Neonatal Intensive Care Units describe the development and implementation of nutrition tools. Tools include Parenteral Nutrition Guidelines, Automated Feeding Protocol, electronic medical record Order Set, Nutrition Time-Out Rounding Tool, and a Discharge Nutrition Recommendations. 15 of 22 participant sites completed a survey regarding tool value and implementation. RESULTS: Reduced growth failure at discharge was observed in four of five NICUs, 11-32% improvement. Tools assisted with earlier TPN initiation (8 h) and reaching full feeds (2-5 days). TPN support decreased by 5 days. 80% of survey respondents rated the tools as valuable. CONCLUSION: Evidence and consensus-based nutrition tools help promote standardization, leading to improved and sustainable outcomes.

Detection and reduction of errors in parenteral nutrition compounding through gravimetric and product control. / [Artículo traducido] Detección y reducción de errores en la elaboración de la nutrición parenteral mediante control gravimétrico y de producto.

OBJECTIVE: To analyze the errors in the preparation of parenteral nutrition in a Pharmacy Service, detected through an already consolidated gravimetric and product quality control, and compare them with those detected during the initial years of implementing this quality control. METHODS: All errors detected through quality control in the compounding of pediatric and adult parenteral nutrition between 2019 and 2021 were prospectively analyzed. This quality control consisted of 3 sequential processes: a visual check, a gravimetric control, and a product control. Errors were classified as gravimetric, when the nutrition had a deviation of more than 5% from the theoretical weight, or as product errors when a qualitative or quantitative error was detected upon reviewing the remainder of the components used. These errors were analyzed in terms of type and the component involved. A comparison was made with the errors detected during the implementation phase of this quality control from 2016 to 2018. RESULTS: A total of 41,809 parenteral nutritions were reviewed, and 345 errors were detected (0.83% of the preparations); of these, 59 errors were found in pediatric nutritions (0.68% of them), and 286 in adult nutritions (0.86% of them). Among these errors, 193 were of gravimetric nature, while 152 were detected through product control. The main components involved in product errors were electrolytes, primarily due to the addition of excessive volumes and the use of incorrect components. A significant absolute reduction of 0.71% (p < 0.05) in the total number of errors was observed when compared to the implementation phase. This reduction was consistent in both gravimetric errors (-0.59%) and product-related errors (-0.12%) (p < 0.05). CONCLUSIONS: Comprehensive quality control of parenteral nutrition preparation is an easily implementable tool that effectively detected and prevented significant errors. Furthermore, its widespread adoption contributed to a reduction in the overall error count.

Reducing Procedural Pain and Avoiding Peripheral Intravenous Catheters by Implementing a Feeding Protocol for Late Preterm Infants: A Quality Improvement Project.

BACKGROUND: Late preterm births account for a large portion of preterm births, yet the optimal method of nutrition and enteral feeding in this population remains unclear and often involves intravenous (IV) fluids. PURPOSE: To develop and implement a late preterm feeding protocol in order to decrease the necessity of IV access, decrease the use of starter parenteral nutrition (PN), and reduce the pain endured by an infant in the neonatal intensive care unit. METHODS: The Plan-Do-Study-Act quality improvement model was utilized as a framework for the implementation of this quality improvement project. A literature review was conducted and subsequently, a feeding protocol was developed and included the more judicious use of starter PN. This protocol was implemented, evaluated, and adopted. A second Plan-Do-Study-Act cycle was completed with the addition of an auto-text reminder incorporated into admission notes in the electronic medical record. RESULTS: The implementation of the protocol significantly reduced placement of IV access and the use of starter (PN) in late preterm infants without considerable differences in balancing measures. The percentage of infants who received peripheral IV access declined considerably from 70% to 42% ( P = .0017) subsequently, less pain endured by the infants. There was a decrease in the initiation of starter PN from 55% to 7% ( P < .00001). IMPLICATIONS FOR PRACTICE: Administering enteral feedings on admission to stable, late preterm infants reduced the need for peripheral IV access and thus decreased pain from this procedure.

Aluminum blood concentration in adult patients: effect of multichamber-bag versus hospital-compounded parenteral nutrition / Concentración sanguínea de aluminio en pacientes adultos: efecto de la nutrición parenteral tricameral frente a la nutrición parenteral elaborada en el hospital

Background: the administration of aluminum-contaminated parenteral nutrition (PN) leads to an accumulation of aluminum. The aim of this study was to assess blood aluminum concentrations (BACs) of inpatients receiving multichamber-bag (MCB) PN compared to those receiving compounded PN. Methods: available BACs were retrospectively gathered from patient charts of adult inpatients receiving PN from 2015 to 2020, and compared depending on the type of PN administered. Long-term PN patients, defined as ≥ 20 days of PN, receiving at least > 10 days of compounded PN, were compared to long-term patients receiving only MCB. Results: a total of 160 BACs were available from 110 patients. No differences were found according to type of PN (mean BAC: 3.11 ± 2.75 for MCB versus 3.58 ± 2.08 µg/L for compounded PN). Baseline total bilirubin, surgery and days with PN were related to higher BACs (coefficient: 0.30 [95 % CI, 0.18-0.42], 1.29 [95 % CI, 0.52-2.07], and 0.06 [95 % CI: 0.01-0.11], respectively). Regarding long-term PN, patients receiving only MCB (n = 21) showed lower BACs compared to the compounded PN (n = 17) [2.99 ± 1.55 versus 4.35 ± 2.17 µg/L, respectively; p < 0.05]. Conclusions: although there were no differences in BAC according to type of PN administered, in long-term PN, MCB PN was associated with lower BACs as compared to compounded PN. (AU)

Antecedentes: la administración de nutrición parenteral (NP) contaminada con aluminio conduce a su acumulación. El objetivo de este estudio fue evaluar las concentraciones de aluminio en sangre (CAS) en pacientes hospitalizados que recibieron NP elaboradas en el hospital o bolsas tricamerales. Métodos: se recogieron retrospectivamente las CAS disponibles de los pacientes hospitalizados con NP durante el período entre 2015 y 2020, comparándose los valores en función del tipo de NP administrada. Se comparan igualmente los valores de pacientes de larga duración, definida como ≥ 20 días de NP, que recibieron al menos > 10 días de NP elaborada frente aquellos de larga duración que recibieron solo NP tricameral. Resultados: se incluyeron un total de 160 CAS de 110 pacientes. No se encontraron diferencias con respecto al tipo de NP (CAS media: 3,11 ± 2,75 para la tricameral frente a 3,58 ± 2,08 µg/L para la elaborada). La bilirrubina total basal, la cirugía y los días con NP se relacionaron con un mayor valor de CAS (coeficiente: 0,30 [IC 95 %: 0,18-0,42], 1,29 [IC 95 %: 0,52-2,07] y 0,06 [IC 95 %: 0,01-0,11], respectivamente). En la NP a largo plazo, los pacientes que recibieron solo NP tricameral (n = 21) mostraron una CAS menor en comparación con el grupo que recibió al menos 10 NP elaboradas (n = 17) [2,99 ± 1,55 versus 4,35 ± 2,17 µg/L, respectivamente; p < 0,05]. Conclusiones: aunque no hubo diferencias de CAS con respecto al tipo de NP administrada, en la NP a largo plazo, la administración de NP tricameral se asoció con CAS menores en comparación con la NP elaborada.

Evidence-based recommendations of the Andalusian Group for Nutrition Reflection and Investigation (GARIN) for the management of adult patients with short bowel syndrome / Recomendaciones basadas en la evidencia del Grupo Andaluz para la Reflexión e Investigación en Nutrición (GARIN) para el manejo del paciente con síndrome de intestino corto

In order to develop evidence-based recommendations and expert consensus for the nutritional management of patients with short bowel syndrome (SBS), we conducted a systematic literature search using the PRISMA methodology plus a critical appraisal following the GRADE scale procedures. Pharmacological treatment with antisecretory drugs, antidiarrheal drugs, and somatostatin contributes to reducing intestinal losses. Nutritional support is based on parenteral nutrition; however, oral intake and/or enteral nutrition should be introduced as soon as possible. In the chronic phase, the diet should have as few restrictions as possible, and be adapted to the SBS type. Home parenteral nutrition (HPN) should be individualized. Single-lumen catheters are recommended and taurolidine should be used for locking the catheter. The HPN's lipid content must be greater than 1 g/kg per week but not exceed 1 g/kg per day, and omega-6 fatty acids (ω6 FAs) should be reduced. Trace element vials with low doses of manganese should be used. Patients with chronic SBS who require long-term HPN/fluid therapy despite optimized treatment should be considered for teduglutide treatment. All patients require a multidisciplinary approach and specialized follow-up. These recommendations and suggestions regarding nutritional management in SBS patients have direct clinical applicability. (AU)

Con el fin de desarrollar recomendaciones basadas en la evidencia y el consenso de expertos para el manejo nutricional de los pacientes con síndrome de intestino corto (SIC), realizamos una búsqueda bibliográfica sistemática utilizando la metodología PRISMA junto a una valoración crítica siguiendo los procedimientos de la escala GRADE. El tratamiento farmacológico con fármacos antisecretores, antidiarreicos y somatostatina contribuye a reducir las pérdidas intestinales. El apoyo nutricional se basa en la nutrición parenteral; sin embargo, la ingesta oral y/o la nutrición enteral deben introducirse lo antes posible. En la fase crónica, la dieta debe tener las menores restricciones posibles y adaptarse al tipo de SIC. La nutrición parenteral domiciliaria (NPD) debe individualizarse. Se recomiendan catéteres de un solo lumen y se debe utilizar taurolidina para bloquear el catéter. El contenido de lípidos de la HPN debe ser superior a 1 g/kg por semana, pero no debe exceder 1 g/kg por día, y debe reducirse el ácido graso omega-6 (AG ω6). Deben utilizarse viales de oligoelementos con dosis bajas de manganeso. Los pacientes con SIC crónico que requieren NPD/fluidoterapia a largo plazo a pesar del tratamiento optimizado deben considerarse para el tratamiento con teduglutida. Todos los pacientes requieren un abordaje multidisciplinar y un seguimiento especializado. Estas recomendaciones y sugerencias con respecto al manejo nutricional de los pacientes con SIC tienen aplicabilidad clínica directa. (AU)

Differential DNA methylation by early versus late parenteral nutrition in the PICU: a biological basis for its impact on emotional and behavioral problems documented 4 years later.

BACKGROUND: The PEPaNIC multicenter randomized controlled trial (RCT) has shown that early administration of supplemental parenteral nutrition (early-PN) as compared with withholding PN for 1 week (late-PN) induced long-term internalizing, externalizing and total emotional/behavioral problems in critically ill children, as observed 4 years later. Early-PN was further shown to alter the methylation status of 37 CpG-sites in leukocyte DNA between admission and discharge from the pediatric intensive care unit (PICU). In a preplanned subanalysis of the PEPaNIC trial, we now investigated whether the altered methylation of these CpG-sites could statistically explain the negative impact of early-PN on emotion/behavior documented 4 years after PICU admission. RESULTS: The combination of DNA methylation data and data on behavior 4 years after PICU admission was available for 403 of the 1440 patients (aged 0-17 years at PICU admission) who were included in the PEPaNIC RCT (192 early-PN and 211 late-PN patients). Mediation analyses with use of bootstrapped multivariable non-linear regression analyses adjusted for baseline risk factors revealed that the adverse alterations by early-PN in methylation of the 37 CpG-sites together statistically explained its harmful impact on internalizing, externalizing and total emotional/behavioral problems. When adding the methylation status of the 37 CpG-sites to the models, the explanatory power improved with a 1.710 to 1.851-fold increase, and the impact of the altered methylation status of the CpG-sites explained the impact of the randomization to early-PN versus late-PN. CONCLUSIONS: Abnormal DNA methylation induced by the early use of PN in the PICU provides a biological basis for its long-term harmful effect on emotion/behavior of critically ill children 4 years after PICU admission.

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.
