Background: Parenteral nutrition (PN) plays a crucial role in nutrition support therapy, yet data on related adverse events (AEs) in practical settings are scarce. To address this, we analyzed AE signals associated with PN treatment from the United States Food and Drug Administration Adverse Event Reporting System (FAERS) database.

Methods: We extracted data from the FAERS database, covering the period from the first quarter (Q1) of 2004 to Q1 of 2024. Drug names and AEs were standardized. We then conducted disproportionality analyses using four different algorithms to evaluate the association between PN and its associated AEs.

Results: We collected a total of 48,890,925 reports from the FAERS database, of which 1642 involved PN-related AEs. After categorization, we identified 21 system organ classes (SOCs), and hepatobiliary disorders were the only significant SOC across all four algorithms. At the preferred term (PT) level, we identified 99 PTs that showed significant disproportionality in all four algorithms. Fat overload syndrome, fatty acid deficiency, parenteral nutrition-associated liver disease (PNALD), Malassezia infection, and Pantoea agglomerans infection were the most prominent PTs. In addition, several potential new AE signals included nervous, cardiac, immune, psychiatric, blood, renal, urinary, and eye disorders.

Conclusion: Our study identified several common and rare PN-related AEs reported in the FAERS database. Patients and healthcare providers should remain vigilant about these AEs. Understanding the risks of PN therapy and establishing practical procedures can help reduce AEs.

Background: This study aimed to investigate and propose novel approaches to calculate muscle quality index (MQI) using muscle mass derived from single-frequency bioelectrical impedance analysis (SF-BIA) and calf circumference in both unadjusted and body mass index (BMI)-adjusted forms. In addition, we examined their prognostic significance in patients with cancer.

Methods: A secondary analysis was conducted on a prospective cohort study of patients with cancer. Handgrip strength was measured. SF-BIA was conducted to estimate appendicular lean soft tissue (ALST, in kilograms). MQI was calculated using three approaches: (1) the ratio of handgrip strength to ALST (MQI_SF-BIA), (2) the ratio of handgrip strength to calf circumference (MQI_{calf circumference}), and (3) the ratio of handgrip strength to BMI-adjusted calf circumference (MQI_{adj. calf circumference}). Maximally selected log-rank was calculated to estimate their cutoff values to predict survival.

Results: Two hundred eighty-four patients were included (51.1% men; median age, 61 years). Solid tumors were the most frequent (89.8%). All approaches to MQI (MQI_SF-BIA, MQI_{calf circumference}, and MQI_{adj. calf circumference}) were independent predictors of 6-month mortality. The found cutoffs were (1) MQI_SF-BIA (<1.52 for men, <0.63 for women), (2) MQI_{calf circumference} (<0.74 for men, <0.24 for women), and (3) MQI_{adj. calf circumference} (<0.75 for men, <0.25 for women).

Conclusion: This study introduces MQI_SF-BIA, MQI_{calf circumference}, and MQI_{adj. calf circumference} as future potential surrogate methods for computing MQI in clinical practice when other robust procedures are unavailable, pending further validation.

The vision of the ASPEN Rhoads Research Foundation is to promote innovation and research discovery to improve nutrition care and health. The Foundation was launched in 1993, incorporated in 2002, and established as a nonprofit 501(c)(3) organization in 2007. On the occasion of American Society for Parenteral and Enteral Nutrition (ASPEN)'s 50th anniversary, this article examines the creation of the Foundation, the state of clinical nutrition research funding, the Foundation's philanthropic mission, and the return on investment of Foundation grant support. To date, 114 investigators have received 2.78 million dollars in funding. The article examines the success of ASPEN research programs and Foundation grant support in career development, leadership, and mentorship. It is important to document a historical account of the ASPEN Rhoads Research Foundation and encourage innovation and discovery and ongoing financial support.

Background: Chyme reinfusion therapy treats patients with high-output fistulas or stomas by returning chyme to the distal gut. The role of this treatment in severe acute intestinal failure is currently unclear. The primary outcome of this study was a successful establishment of chyme reinfusion therapy, defined by the ability to replace parenteral nutrition for nutrition support.

Methods: A descriptive cohort study of adult patients with severe acute intestinal failure due to a high-output stoma and distal mucus fistula or a high-output small intestinal fistula receiving chyme reinfusion therapy was undertaken. The effect of chyme reinfusion therapy on parenteral nutrition requirements, medication, nutrition status, liver function, and treatment cost were studied.

Results: Twenty-four patients commenced treatment for a median of 44 (range, 3-571; total, 2263) days. Fifteen (62.5%) were successfully established for 1208 days, and nine continued treatment at home. Parenteral requirements, including volume, energy and nitrogen content, and frequency, were significantly reduced (P = 0.002), whereas anthropometric measurements remained stable. However, chyme therapy was not tolerated in nine patients (37.5%), and only two (8.3%) weaned fully from parenteral nutrition. Chyme reinfusion therapy was associated with a 47.6% reduction in parenteral energy requirements, 42.8% reduction in nitrogen, and 33.3% reduction in volume of parenteral nutrition requirements. Treatment was associated with a net cost of £30.05 ($40.27) per patient per day.

Conclusion: Chyme reinfusion therapy was associated with reductions in the need for parenteral therapy and medication but did not replace parenteral nutrition or result in a significant cost saving.

Background: Parenteral nutrition (PN) is a high-risk medication, and its prescription and administration requires extensive training. Difficulties inherent with bedside teaching have made teaching these concepts challenging. Currently, no knowledge assessment tools with validity evidence exist to test the effectiveness of new PN teaching interventions. We sought to develop and provide validity evidence for a pediatric PN knowledge test to measure the effectiveness of future teaching interventions.

Methods: We created a multiple-choice question knowledge assessment tool that underwent content validation by PN experts and was emailed to potential participants. We evaluated the knowledge assessment tool for factorial validity, internal consistency reliability, and discriminant validity.

Results: We enrolled 103 medical students (40%), residents and fellow trainees (55%), and attending physicians (5%) into the study between October 2021 and October 2022. Five of the 30 questions performed poorly based on their nonsignificant contribution to the primary aim of assessing pediatric PN knowledge. Following the exclusion of those questions, the knowledge assessment tool demonstrated an acceptable model fit, and the root mean squared error of approximation was <5%. The omega coefficient was 0.829, indicating acceptable levels of reliability, and using an analysis of variance test (ANOVA) demonstrated significant differences between groups, showing good discrimination between levels of experience (F[2, 80] = 39.002; P < 0.001).

Conclusion: We have developed and provided validity evidence for a multiple-choice question knowledge test that may be used by educators and programs to evaluate knowledge of pediatric PN in physicians and trainees.

Objectives: The main objective of this study was to analyze the reasons for customizing parenteral nutrition (PN) in pediatric patients admitted to a quaternary hospital.

Methods: We performed a descriptive cohort study on 264 hospitalized children receiving PN. Anthropometric, biochemical, and hospitalization data were collected from patient records. Unequivocal reasons for customizing PN were defined as situations precluding prescription of a standard adult/teenager PN and included renal and/or liver failure, energy-protein adequacy, and elevated mineral and triglyceride levels.

Results: A total of 264 patients, with a median age of 2.2 years (IQR: 0.3-9.0 years), comprising intensive care (n = 216; 81.8%) and malnourished (n = 91; 36.1%) patients, were evaluated. In the first 48 h, 87.9% (n = 232) of the sample required customized PN for energy-protein adequacy (210 of 232), maintained over subsequent days in most cases. Among patients requiring second individualization, mineral disturbance was the main reason observed, especially within the first 4 days of PN use (n = 21; 60%). Unequivocal reasons for customizing PN occurred in 97.4% (n = 226) of cases in the first 48 h; 96.2% (n = 177) of cases on the fourth day; and 90.1% (n = 92) of cases on the seventh day of PN use. An inverse correlation was found between weight/age z score and number of second individualizations (r = -0.222; P = 0.002).

Conclusion: Customized PN proved essential, especially for younger, malnourished, and intensive care patients. Investment in training a Nutritional Multidisciplinary Therapy Team and acquiring a specific electronic system for prescribing PN is suggested.

Background: Indirect calorimetry is recommended for directing energy provision in the intensive care unit (ICU). However, limited reports exist of measured energy expenditure according to the phases of critical illness in large cohorts of patients during ICU admission. This study aimed to analyze measured energy expenditure overall in adult patients who were critically ill and across the different phases of critical illness.

Methods: Indirect calorimetry measurements completed at a mixed ICU between January 2010 and July 2019 were eligible. Measured energy expenditure was analyzed and reported as kcal/day and kcal/kg/day overall, as the percentage increase above predicted basal metabolic rate and according to the phases of critical illness; acute early (day 1-2), acute late (day 3-7) and recovery (>7 days) phases using mixed effects linear modelling.

Results: There were 629 patients with 863 measurements included; age mean (standard deviation) 48 (18) years, 68% male and 269 (43%) with a traumatic brain injury. Measured energy expenditure overall was 2263 (626) kcal/day (30 (7) kcal/kg/day), which corresponded to a median [interquartile range] of 135 [117-155] % increase above predicted basal metabolic rate. In patients with repeat measurements (n = 158), measured energy expenditure (mean ± standard error) increased over time; 27 ± 0.5 kcal/kg/day in the early acute, 30 ± 0.4 kcal/kg/day in the late acute, and 31 ± 0.4 kcal/kg/day in the recovery phases of critical illness (P < 0.001).

Conclusion: In a large cohort of ICU patients, measured energy expenditure was 135% above the basal metabolic rate and increased from the early acute to the late acute and recovery phases of critical illness.

Introduction: Intestinal failure-associated liver disease covers a spectrum of conditions from mild to end-stage disease. Currently, there are 9 diagnostic criteria divided to four categories: cholestasis, steatosis, fibrosis, and unclassified. Our aim was to evaluate the application of these criteria to patients with chronic severe liver disease in patients with intestinal failure.

Methods: This was a cross-sectional study of patients attending the home parenteral nutrition clinic of a national UK reference intestinal failure center from March 2015 to December 2019. Exclusion criteria included active malignancy, home parenteral nutrition for <6 months duration, and liver transplantation. Clinically significant intestinal failure-associated liver disease was defined as moderate-severe fibrosis or cirrhosis on liver biopsy and/or radiological imaging compatible with liver cirrhosis.

Results: Two hundred and twenty-one patients were included (age at home parenteral nutrition initiation: 50 ± 16.0 years; 63.6% female). There was a wide range of intestinal failure-associated liver disease point prevalence depending on the established criteria used (2.9%-35.1%). Twenty-three patients (9.5%) were diagnosed with clinically significant intestinal failure-associated liver disease, but no patient with clinically significant intestinal failure-associated liver disease met all diagnostic criteria, and 6 of 23 (26.1%) did not fit any of the established criteria.

Conclusions: Intestinal failure-associated liver disease is a poorly defined medical condition, and current noninvasive diagnostic methods are unreliable in predicting disease severity. Further studies are needed to develop the definition to reflect that intestinal failure-associated liver disease is a spectrum of disease that includes chronic severe liver disease and improve methods of disease diagnosis.

Children use nasogastric tubes (NGTs) to ensure optimum nutrition and medication delivery when oral feeding fails or when they experience faltering growth. Although this method is less invasive, children may experience complications associated with NGTs. There is a gap in the literature regarding the types and prevention of complications of NGTs in the pediatric population at home. This review determines at-home complications associated with NGTs in the pediatric population (aged 0-18 years) and the type of education and support provided to caregivers. Databases MEDLINE, Embase using the Ovid interface, and CINAHL using the EBSCOhost interface were searched for relevant studies from January 1946 to November 2022. Twenty-four articles were found, of which 16 studies with 902 children with NGTs feeding were systematically reviewed. Two themes emerged: (1) prevalence and types of NGT complications and (2) preventable complications and education/management strategies for prevention. Seven studies reported main complications of vomiting, retching and gagging, nausea, aspiration, local granulation tissue, and inadvertent removal, with two studies reporting no complications. Most complications were managed at home, suggesting caregivers were able to address issues without seeking additional medical intervention. Key recommendations to mitigate complications included training caregivers in NGT management, troubleshooting common complications, and evaluating caregiver competency before discharge. This systematic review emphasized the need for structured training programs to improve caregiver competence and safety practices, highlighting key areas for clinical improvement, including caregiver education, reducing at-home complications, and standardizing care for children using NGTs.
