Approximately 50% of acute intestinal failure (AIF) patients on short-term parenteral nutrition (PN) have intestinal failure-associated liver disease (IFALD) without effect on hospital length of stay and mortality.

INTRODUCTION: Patients with intestinal failure (IF) are often dependent on PN for provision of calories and nutrients for survival. Similar to chronic intestinal failure (CIF) patients, those who have AIF are also at risk of IFALD, which is a poorly understood but potentially fatal condition. The local incidence of IFALD amongst AIF patients is not known. OBJECTIVES: The primary objective of this study was to determine the incidence of IFALD in AIF patients on short-term PN. Secondary objectives were to analyse patient and PN risk factors of IFALD, and clinical outcomes of length of stay (LOS) and inpatient mortality. DESIGN: This was a retrospective cross-sectional cohort study of hospitalised adult patients with AIF prescribed with short-term PN. All adult patients aged 21 years and above who received PN for at least 5 consecutive days and had normal liver function tests (LFTs) at the time of PN initiation were included in this study. RESULTS: A total of 171 patients were enrolled in this study, with 77 (45%) having deranged LFTs at the end of PN therapy and categorised under the IFLAD group. The patient cohort was predominantly male (92 [54%]) and had a median age of 68 years (IQR 59-76). Patients with IFALD at the end of PN therapy had higher diabetes prevalence (36% vs 26%, p = 0.2) and were on PN for a longer duration (median [IQR]: 12 [8-17] vs 8 [6-15] days, p = 0.003) than those without IFALD. There were no significant differences in patient and PN characteristics between the IFLAD and non-IFALD group. The multivariable models showed that the IFALD cohort had longer hospital stays (HR 0.90, 95% CI 0.65-1.23) and lower odds of inpatient death (OR 0.75, 95% CI 0.12-4.60), though both findings are not statistically significant (p = 0.5, 0.7). CONCLUSION: In this study, IFALD is a common phenomenon in AIF and the incidence was found to be an estimated 50% amongst patients on short-term PN with similar clinical outcomes between the two groups.

The impact of guideline recommended protein intake on mortality and length of intensive care unit and hospital stay in critically ill adults: A systematic review.

International guidelines recommend a target protein intake of ≥1.2 g/kg/day to all critically ill patients for optimal outcomes. There are however various conflicting data related to this recommendation. The primary objective of this review was to compare a protein intake group (≥1.2 g/kg/day) with a lower protein intake group (<1.2 g/kg/day) in critically ill adult patients on mortality, length of intensive care unit (ICU) and hospital stay. Secondly, the effect of protein intake on length of mechanical ventilation, adverse nutrition-related events and muscle mass and strength parameters were investigated. Sixteen randomised controlled trials (RCTs) of adult patients admitted to an intensive or high care unit and receiving nutrition support in the form of enteral- and/or parenteral nutrition were selected against prespecified eligibility criteria. Two independent reviewers extracted relevant data and assessed the risk of bias of the included studies. Review Manager 5.4.1 was used to analyse data and GRADE (Grading of Recommendations, Assessment, Development, and Evaluations) was used to evaluate the certainty of the evidence. The higher protein group, when compared to the lower protein group, probably results in little to no difference in mortality (risk ratio [RR] 1.01; 95% confidence interval [CI]: 0.89 to 1.14; moderate-certainty evidence); with a probable slight increase in length of ICU stay (mean difference [MD] 0.33; 95% CI -0.57 to 1.23; moderate-certainty) and length of hospital stay (MD 1.72; 95% CI -0.58 to 4.01; moderate-certainty evidence), on average. For secondary outcomes, it was found that the higher protein group probably does not reduce the length of mechanical ventilation (MD 0.08; 95% CI -0.38 to 0.53; moderate-certainty evidence). Higher protein group probably reduces the occurrence of diarrhoea and high gastric residual volume and may reduce the occurrence of constipation. It may also increase nitrogen balance (MD 3.66; 95% CI 1.81 to 5.51; low-certainty evidence). Importantly, there does not seem to be harm associated with the higher protein group, though it should be mentioned that for many of the adverse events in this study, the certainty of evidence was low or very low.

LLL 44-1 Micronutrients in clinical nutrition: Trace elements.

BACKGROUND: Trace elements are an essential component of metabolism and medical nutrition therapy, with key roles in metabolic pathways, antioxidation, and immunity, which the present course aims at summarizing. RESULTS: Medical nutrition therapy includes the provision of all essential trace elements. The clinical essential issues are summarized for Copper, Iron, Selenium, Zinc, Iodine, Chromium, Molybdenum, and Manganese: the optimal analytical techniques are presented. The delivery of all these elements occurs nearly automatically when the patient is fed with enteral nutrition, but always requires separate prescription in case of parenteral nutrition. Isolated deficiencies may occur, and some patients have increased requirements, therefore a regular monitoring is required. The clinicians should always consider the impact of inflammation on blood levels, mostly lowering them even in absence of deficiency. CONCLUSION: This text summarises the most relevant clinical manifestations of trace element depletion and deficiency, the difficulties in assessing status, and makes practical recommendations for provision for enteral and parenteral nutrition.

Indications for Intestinal Transplantation.

Outcomes for patients with chronic intestinal failure have improved with organization of experts into multidisciplinary teams delivering care in intestinal rehabilitation programs. There have been improvements in understanding of intestinal failure complications as well as development of newer therapies that have amplified the improvements in survival. In spite of this encouraging trend, patients who fail PN are often referred too late for intestinal transplantation. The author proposes a more rational framework that might allow earlier identification of intestinal failure patients at risk for PN-failure, who could appropriately be considered earlier for intestinal transplantation with improvements in overall outcomes.

Early versus late parenteral nutrition in term and late preterm infants: a randomised controlled trial.

BACKGROUND: There is limited evidence regarding the optimal time to commence parenteral nutrition (PN) in term and late preterm infants. DESIGN: Single-centre, non-blinded, exploratory randomised controlled trial. SETTING: A level-3 neonatal unit in a stand-alone paediatric hospital. PATIENTS: Infants born ≥34 weeks of gestation and ≤28 days, who needed PN. Eligible infants were randomised on day 1 or day 2 of admission. INTERVENTIONS: Early (day 1 or day 2 of admission, N=30) or late (day 6 of admission, N=30) PN. MAIN OUTCOME MEASURES: Plasma phenylalanine and F2-isoprostane levels on day 4 and day 8 of admission. Secondary outcomes were amino-acid and fatty-acid profiles on day 4 and day 8, and clinical outcomes. RESULTS: The postnatal age at randomisation was similar between the groups (2.3 (SD 0.8) vs 2.3 (0.7) days, p=0.90). On day 4, phenylalanine levels in early-PN infants were higher than in late-PN (mean (SD) 62.9 (26.7) vs 45.5 (15.3) µmol/L; baseline-adjusted percentage difference 25.8% (95% CI 11.6% to 39.9%), p<0.001). There was no significant difference in phenylalanine levels between the two groups on day 8. There was no significant difference between the groups for F2-isoprostane levels on day 4 (early-PN mean (SD) 389 (176) vs late-PN 419 (291) pg/mL; baseline-adjusted percentage difference: -4.4% (95% CI -21.5% to 12.8%) p=0.62) and day 8 (mean (SD) 305 (125) vs 354 (113) pg/mL; adjusted mean percentage difference -16.1 (95% CI -34.1 to 1.9) p=0.09).Postnatal growth restriction for weight was less severe in the early-PN group (change in weight z-score from baseline to discharge: -0.6 (0.6) vs -1.0 (0.6); p=0.02). The incidence of hyperglycaemia was greater in the early-PN group (20/30 (66.7%) vs 11/30 (36.7%), p=0.02). CONCLUSIONS: The timing of the commencement of PN did not seem to affect the degree of oxidative stress in critically ill term and late preterm infants. The effect of transiently high plasma phenylalanine with early PN on clinical outcomes requires further investigation. TRIAL REGISTRATION NUMBER: ACTRN12620000324910.

Association of Standardized Parenteral Nutrition with Early Neonatal Growth of Moderately Preterm Infants: A Population-Based Cohort Study.

In preterm infants, early nutrient intake during the first week of life often depends on parenteral nutrition. This study aimed to evaluate the influence of standardized parenteral nutrition using three-in-one double-chamber solutions (3-in-1 STD-PN) on early neonatal growth in a cohort of moderately preterm (MP) infants. This population-based, observational cohort study included preterm infants admitted to neonatal centers in the southeast regional perinatal network in France. During the study period, 315 MP infants with gestational ages between 320/7 and 346/7 weeks who required parenteral nutrition from birth until day-of-life 3 (DoL3) were included; 178 received 3-in-1 STD-PN solution (56.5%). Multivariate regression was used to assess the factors associated with the relative body-weight difference between days 1 and 7 (RBWD DoL1-7). Infants receiving 3-in-1 STD-PN lost 36% less body weight during the first week of life, with median RBWD DoL1-7 of -2.5% vs. -3.9% in infants receiving other PN solutions (p < 0.05). They also received higher parenteral energy and protein intakes during the overall first week, with 85% (p < 0.0001) and 27% (p < 0.0001) more energy and protein on DoL 3. After adjusting for confounding factors, RBWD DoL1-7 was significantly lower in the 3-in-1 STD-NP group than in their counterparts, with beta (standard deviation) = 2.08 (0.91), p = 0.02. The use of 3-in-1 STD-PN provided better energy and protein intake and limited early weight loss in MP infants.

Electron Microscopy for the Stability Assessment of Parenteral Nutrition Admixtures: Focus on Precipitation.

(1) Background: parenteral nutrition (PN) is indispensable for patients unable to receive oral or enteral feeding. However, the complexity of PN solutions presents challenges regarding stability and compatibility. Precipitation reactions may occur. The most frequent is the formation of calcium phosphate (Ca-P). The different factors influencing these reactions must be considered to ensure patient safety. (2) Methods: eight paediatric PN solutions were prepared, following standard protocols. Samples were stored at room temperature and in a refrigerator. Electron microscopy, coupled with energy dispersive X-ray spectroscopy (EDS), was employed. Precipitates were analysed for composition and morphology. (3) Results: precipitates were observed in all samples, even at day 0. Crystalline structures, predominantly composed of calcium or magnesium, sometimes associated with chlorine or phosphorus, were detected. Additionally, amorphous precipitates, contained heterogeneous compositions, including unexpected elements, were identified. (4) Conclusions: various precipitates, primarily calcium- or magnesium-based, can form in PN solutions, although it is not expected that they can form under the real conditions of use. Calcium oxalate precipitation has been characterised, but the use of organic calcium and phosphate salts appears to mitigate calcium phosphate precipitation. Electron microscopy provides interesting results on NP precipitation, but sample preparation may present technical limitations that affect the interpretation of the results.

Parenteral Nutrition in Palliative Cancer Care: Detrimental, Futile, or Beneficial?

Palliative cancer care patients may live for a long time, but malnutrition worsens the prognosis. Parenteral nutrition (PN) is suitable for replenishing a calorie deficit, but its advantages and tolerance late in the cancer trajectory are debated. We examined symptom development in hospitalized patients with and without PN. A total of 21 palliative cancer care patients receiving PN and 155 palliative cancer care patients not receiving PN during hospitalization in a specialized unit were retrospectively compared. We studied symptom intensity at admission, symptom relief during the hospital stay, and survival. The patients had locally advanced or metastatic cancer, a mean age of 70 years, and their median ECOG performance status was III. Symptom burden at admission was similar in the compared groups. Symptom relief during hospitalization was also similar. However, patients already on PN at admission reported more nausea and patients receiving PN during hospitalization reported better nausea relief compared to patients not receiving this intervention. Overall median survival was less than two months and similar in the compared groups. Based on a limited number of observations and a suboptimal study design, we were not able to demonstrate an increased symptom burden for palliative cancer care patients receiving PN late in the disease trajectory.

Expert consensus report on lipid mediators: Role in resolution of inflammation and muscle preservation.

This meeting report presents a consensus on the biological aspects of lipid emulsions in parenteral nutrition, emphasizing the unanimous support for the integration of lipid emulsions, particularly those containing fish oil, owing to their many potential benefits beyond caloric provision. Lipid emulsions have evolved from simple energy sources to complex formulations designed to improve safety profiles and offer therapeutic benefits. The consensus highlights the critical role of omega-3 polyunsaturated fatty acids (PUFAs), notably eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), found in fish oil and other marine oils, for their anti-inflammatory properties, muscle mass preservation, and as precursors to the specialized pro-resolving mediators (SPMs). SPMs play a significant role in immune modulation, tissue repair, and the active resolution of inflammation without impairing host defense mechanisms. The panel's agreement underscores the importance of incorporating fish oil within clinical practices to facilitate recovery in conditions like surgery, critical illness, or immobility, while cautioning against therapies that might disrupt natural inflammation resolution processes. This consensus not only reaffirms the role of specific lipid components in enhancing patient outcomes, but also suggests a shift towards nutrition-based therapeutic strategies in clinical settings, advocating for the proactive evidence-based use of lipid emulsions enriched with omega-3 PUFAs. Furthermore, we should seek to apply our knowledge concerning DHA, EPA, and their SPM derivatives, to produce more informative randomized controlled trial protocols, thus allowing more authoritative clinical recommendations.

Optimizing Intravenous Access for Long-Term Parenteral Nutrition.

PURPOSE OF REVIEW: Securing safe and effective intravenous (IV) access is of utmost importance for administering parenteral nutrition (PN). Sustaining this access can indeed pose challenges, especially when dealing with the risk of complications associated with long-term PN. This review emphasizes best practices to optimize intravenous access and reviews the current evidence-based recommendations and consensus guidelines. RECENT FINDINGS: An individualized approach when selecting central venous catheters (CVC) is recommended, considering the estimated duration of need for IV access and the number of lumens needed. Established and novel approaches to minimize complications, including infection and thrombosis, are recognized. These include placement and positioning of the catheter tip under sonographic guidance and the use of antimicrobial lock therapies. Moreover, when possible, salvaging CVCs can reduce the risk of vascular access loss. CVC selection for patients requiring PN depends on several factors. Carefully reviewing an individual patient's clinical characteristics and discussing options is important. Given the increased infection risk, CVC lumens should be minimized. For long-term PN beyond 6 months, using CVCs with skin barriers and larger diameters should be considered.

Is neurodevelopment impaired in Brazilian children with intestinal failure on prolonged parenteral nutrition? A single center study.

PURPOSE: To assess the neurodevelopment outcomes of children younger than 42 months of age with intestinal failure (IF) using prolonged parenteral nutrition (PN) followed by a Pediatric Multidisciplinary Intestinal Rehabilitation Program from a public tertiary hospital in Brazil. METHODS: Bayley III scale was administered in children aged 2 to 42 months with IF and receiving PN for more than 60 days. Composite scores in cognitive, motor, and language domains were analyzed. Developmental delay was defined as a performance 2 standard deviations (SD) below the average at the 3 domains. Association between Bayley III composite scores and clinical variables related to IF were tested. RESULTS: Twenty-four children with median (IQR) age of 17.5 months (9-28.5) were studied, 58.3% were male. Developmental delay was found in 34%, 33% and 27% of the patients in cognitive, motor, and language domains, respectively. There was no significant association between the Bayley-III composite scores and length of hospitalization, prematurity, and number of surgical procedures with anesthesia. CONCLUSION: The study demonstrated impairments in the cognitive, motor and language domains in approximately one-third of young patients with IF on prolonged PN.

Nutritional Outcomes of Bowel Lengthening Procedure in Patients with Short Bowel Syndrome.

BACKGROUND: Although parenteral nutrition (PN) significantly improves mortality rates in pediatric short bowel syndrome (SBS), long-term PN has many possible complications and impacts quality of life. Bowel lengthening procedures (BLPs) increase the contact surface of food and the intestinal mucosa and enable the better absorption of nutrients and liquids, possibly leading to a PN decrease. METHODS: We retrospectively reviewed the data of patients with short bowel syndrome who underwent BLPs in the period from January 2016 to January 2022. Overall, eight patients, four male, five born prematurely, underwent BLPs. RESULTS: There was a significant decrease in the percentage of total caloric intake provided via PN and PN volume after the BLPs. The more evident results were seen 6 months after the procedure and at the last follow-up, which was, on average, 31 months after the procedure. Two patients were weaned off PN after their BLPs. Patients remained well nourished during the follow-up. CONCLUSIONS: The BLP led to a significant decrease in PN needs and an increase in the food intake; however, significant changes happened more than 6 months after the procedure.

Compatibility studies of selected multichamber bag parenteral nutrition with fluconazole.

OBJECTIVE: Fluconazole (FLZ) is a drug widely used in the treatment of fungal infections including the treatment of immunocompromised patients, HIV-infected patients, and cancer patients. Critically ill patients often require the administration of drugs with parenteral nutrition (PN). The safety of this combination should be defined before the drug and PN are administered in one infusion line. This study aimed to determine the compatibility of FLZ with six selected multichamber bag parenteral nutrition. METHODS: FLZ solution for infusion was combined with PNs in appropriate proportions, considering most clinical situations resulting from different possible administration rates of the preparations. Samples were visually assessed, and pH, osmolality, turbidity, particle size (dynamic light scattering and light obscuration methods), and zeta potential were measured. These measurements were made immediately after combining the solutions and after 4 h of storage at 23 ± 1°C. RESULTS: FLZ combined with PNs did not cause changes observed visually. The turbidity of the samples was <0.4 NTU. The average particle size of the lipid emulsion was below 300 nm, and the PFAT5 parameter was ≤0.02%. The absolute value of the zeta potential of the PN + FLZ samples was higher for 5 out of 6 PN than the corresponding value for PN immediately after activation. Changes in pH and osmolality during 4 h of sample observations were within acceptable limits. CONCLUSION: Compatibility of the FLZ with six multichamber bag PN was confirmed. Hence, those preparations can be administered to patients in one infusion line using the Y-site.

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.

Evaluation of Arsenic and Cobalt Levels in Pediatric Patients Receiving Long-Term Parenteral Nutrition.

This study continues the research in which we determined the concentration of aluminum in children receiving long-term parenteral nutrition (LPN). Since our results were interesting, we decided to assay arsenic (As) and cobalt (Co) in the collected material, which, like aluminum, constitute contamination in the mixtures used in parenteral nutrition. Excesses of these trace elements in the human body are highly toxic, and deficiencies, particularly in the case of Co, can lead to various complications. The aim of this study was to determine the impact of LPN in children on their serum levels of As and Co, as well as the excretion of these elements in urine, and to compare them with a control group of healthy children. The study group consisted of 83 children receiving home parenteral nutrition from two Polish centers, while the control group included 121 healthy children. In both groups, the levels of As and Co in serum and urine were measured. The elemental compositions of the samples were determined using inductively coupled plasma mass spectrometry (ICP-MS). It was demonstrated that the children receiving LPN did not have increased As exposure compared to the controls. Greater exposure compared to the control group was shown for Co. In conclusion, children receiving LPN are not exposed to As, and even though the concentrations of Co in serum and urine were higher in the LPN group than in the healthy controls, neither trace element poses a health threat to children requiring LPN.

Proactive Use of a Human Milk Fat Modular in the Neonatal Intensive Care Unit: A Standardized Feeding Protocol.

An exclusive human milk diet (EHMD) and standardized feeding protocols are two critical methods for safely feeding very low birth weight (VLBW) infants. Our institution initiated a standardized feeding protocol for all VLBW infants in 2018. In this protocol, a human milk fat modular was used only reactively when an infant had poor weight gain, fluid restriction, or hypoglycemia. As part of our NICU quality improvement program, internal utilization review data revealed a potential opportunity to improve growth and reduce costs. While maintaining the EHMD, a simple feeding guideline process change could provide cost savings without sacrificing caloric density or growth. We examined this process change in pre-post cohorts of VLBW infants. METHODS: Our revised feeding protocol, established in October 2021, called for a human milk fat modular (Prolact CR) to be added to all infant feeding when parenteral nutrition (PN) and lipids were discontinued. The human milk fat modular concentration is 4 mL per 100 mL feed, providing approximately an additional 2 kcal/oz. We tracked data to compare (1) the use of the human milk fat modular, (2) the use of the human milk +8 fortifier, (3) overall growth before and after feeding protocol changes, and (4) cost differences between protocols. RESULTS: Thirty-six VLBW infants were followed prospectively upon the introduction of the revised feeding protocol. In the revised era, the need for human milk +8 fortifier decreased from 43% to 14%. The decrease in the cost of a more costly fortifier provided a cost savings of USD 2967.78 on average per infant. Overall growth improved from birth to discharge, with severe malnutrition declining from 3.3% to 2.7% and moderate malnutrition declining from 37% to 8%. CONCLUSIONS: With the proactive use of a human milk fat modular in a standardized feeding protocol, our VLBW infants showed improved growth, lower malnutrition rates, and decreased use of higher caloric fortifiers.

Combination of Parenteral Amino Acid Infusion and Intermittent Loading Exercise Ameliorates Progression of Postoperative Sarcopenia in Rat Model.

Postoperative sarcopenia is associated with poor outcomes in hospitalized patients. However, few studies have focused on short-term postoperative sarcopenia. Furthermore, the influence of nutritional management using amino acids (AAs) comprising a peripheral parenteral nutrition (PPN) solution and its combination with exercise (Exc) is unclear. Hence, we established a postoperative sarcopenic rat model to evaluate the effects of parenteral AA infusion combined with Exc on skeletal muscles and investigate the underlying mechanisms involved in the amelioration of muscle atrophy. Male F344 rats underwent surgery followed by hindlimb suspension (HS) for 5 days. The rats were divided into AA (-), AA (+), AA (-)-Exc, and AA (+)-Exc groups. They were continuously administered a PPN solution with or without AA at 98 kcal/kg/day. The Exc groups were subjected to intermittent loading for 1 h per day. Postoperative sarcopenic rats exhibited decreased muscle strength and mass and an upregulated ubiquitin-proteasome system, autophagy-lysosome system, and fast-twitch fiber-related genes, especially in the AA (-) group. The AA (+)-Exc group exhibited attenuated decreased muscle strength, increased gastrocnemius mass, and a suppressed upregulation of muscle atrophy- and fast-twitch fiber-related genes. Therefore, parenteral AA infusion combined with Exc may be effective in preventing postoperative sarcopenia in hospitalized patients.

Incidence of metabolic bone disease in neonates under 32 gestational weeks at the Hospital Universitario de Santander in Colombia. / Incidencia de enfermedad metabólica ósea en neonatos con menos de 32 semanas de gestación en el Hospital Universitario de Santander en Colombia

INTRODUCTION: Metabolic bone disease of premature infants is a rare complication characterized by a lower mineral content in bone tissue. OBJECTIVE: To establish the incidence of metabolic bone disease in premature infants and to determine associated risk factors. MATERIALS AND METHOD: We conducted a descriptive prospective cohort study for one year in all newborns under 32 gestational weeks, or 1,500 g, at the Hospital Universitario de Santander to determine the incidence of metabolic bone disease. We collected demographic data and prenatal histories of the selected patients, and later, we measured serum alkaline phosphatase and serum phosphorus at the third week of birth, having as reference values for diagnosis less than 5.6 mg/dl for the first one and more than 500 UI/L for the second one. We applied statistical tools for data analysis, such as average proportions, dispersion, distribution and association measures, and binomial regression. RESULTS: From a total of 58 patients, 7 had a diagnosis of metabolic bone disease, with an incidence of 12%. The weight was reported as an independent variable for the development of the disease, being significant in children under 1,160 g, as well as prolonged parenteral nutrition for more than 24 days. When performing the multivariate analysis, low weight and short time of parenteral nutrition appeared as risk factors; in the same way, maternal age below 22 years is associated with a higher relative risk, even more than a newborn weight inferior to 1,160 g. CONCLUSION: Establishing an early intervention in patients with metabolic bone disease enhancing risk factors, such as low weight and prolonged parenteral nutrition, is critical to prevent severe complications.

Durante un año, se realizó un estudio prospectivo de cohorte, descriptivo, con todos los neonatos nacidos con menos de 32 semanas de gestación o un peso menor de 1.500 g en el Hospital Universitario de Santander. Se recolectaron datos demográficos y antecedentes prenatales de los pacientes seleccionados. A la tercera semana de nacimiento, se midieron la fosfatasa alcalina y el fósforo sérico, tomando como valores de referencia diagnóstica aquellos inferiores a 5,6 mg/dl para el primero y aquellos mayores de 500 UI/L para la segunda. Para el análisis de la información, se emplearon herramientas estadísticas, como proporciones de promedios, medidas de dispersión, distribución y asociación, y regresión binomial. Resultados. De un total de 58 pacientes, 7 tuvieron diagnóstico de enfermedad metabólica ósea, con una incidencia del 12 %. De las variables estudiadas, el peso se reportó como una variable independiente para el desarrollo de la enfermedad, significativa en aquellos neonatos con peso menor de 1.160 g, al igual que la nutrición parenteral prolongada por más de 24 días. Al hacer el análisis multivariado, La edad materna menor de 22 años representó un riesgo relativo mayor, en comparación con un peso inferior a 1.160 g. Conclusión. Se estableció la importancia de una intervención temprana en pacientes con factores de riesgo para enfermedad metabólica ósea, como bajo peso (menor de 1.160 g) y nutrición parenteral prolongada (mayor de 24 días), con el fin de prevenir complicaciones graves.

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.

A clinical consensus guideline for nutrition in infants with congenital diaphragmatic hernia from birth through discharge.

OBJECTIVE: To develop a consensus guideline to meet nutritional challenges faced by infants with congenital diaphragmatic hernia (CDH). STUDY DESIGN: The CDH Focus Group utilized a modified Delphi method to develop these clinical consensus guidelines (CCG). Topic leaders drafted recommendations after literature review and group discussion. Each recommendation was sent to focus group members via a REDCap survey tool, and members scored on a Likert scale of 0-100. A score of > 85 with no more than 25% outliers was designated a priori as demonstrating consensus among the group. RESULTS: In the first survey 24/25 recommendations received a median score > 90 and after discussion and second round of surveys all 25 recommendations received a median score of 100. CONCLUSIONS: We present a consensus evidence-based framework for managing parenteral and enteral nutrition, somatic growth, gastroesophageal reflux disease, chylothorax, and long-term follow-up of infants with CDH.
