Nutrició parenteral; Alumini; ToxicitatParenteral nutrition; Aluminum; ToxicityNutrición parenteral; Aluminio; ToxicidadBackground: 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.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
Parenteral Nutrition Overview
Parenteral nutrition (PN) is a life-saving intervention for patients where oral or enteral nutrition (EN) cannot be achieved or is not acceptable. The essential components of PN are carbohydrates, lipids, amino acids, vitamins, trace elements, electrolytes and water. PN should be provided via a central line because of its hypertonicity. However, peripheral PN (with lower nutrient content and larger volume) can be administered via an appropriate non-central line. There are alternatives for the compounding process also, including hospital pharmacy compounded bags and commercial multichamber bags. PN is a costly therapy and has been associated with complications. Metabolic complications related to macro and micronutrient disturbances, such as hyperglycemia, hypertriglyceridemia, and electrolyte imbalance, may occur at any time during PN therapy, as well as infectious complications, mostly related to venous access. Long-term complications, such as hepatobiliary and bone disease are associated with longer PN therapy and home-PN. To prevent and mitigate potential complications, the optimal monitoring and early management of imbalances is required. PN should be prescribed for malnourished patients or high-risk patients with malnutrition where the feasibility of full EN is in question. Several factors should be considered when providing PN, including timing of initiation, clinical status, and risk of complications
Clinical, Ergonomic, and Economic Outcomes With Multichamber Bags Compared With (Hospital) Pharmacy Compounded Bags and Multibottle Systems: A Systematic Literature Review
Preparados estándar de nutrición parenteral en situaciones clínicas complejas
Objetivo: Los preparados binarios y ternarios de nu-trición parenteral, en determinados casos pueden ver su utilidad limitada. El objetivo de este estudio es establecer situaciones de difícil manejo nutricional y analizar el tipo de fór-mula utilizada en estas situaciones. Material y métodos: Se incluyen pacientes tratados con nutrición parenteral durante 9 meses. Se definen tres situaciones clínicamente complejas: larga dura-ción, con más de 25 días; insuficiencia renal, uremia > 20 mmol/L o creatinina sérica > 200 µmol/L; e insufi-ciencia hepática, bilirrubina total > 30 mmol/L o ALT > 2 µkat/L y fosfatasa alcalina > 3 µkat/L o GGT > 3 µkat/L. Se estudian la mortalidad e hipoalbuminemia (< 35 g/L) y se comparan mediante un test de Ji cua-drado (p < 0,05) al resto de los pacientes. La utilización de fórmulas individualizadas se estudia con un modelo de regresión logística múltiple, la variable dependiente es la administración o no de fórmulas individualizadas y las variables independientes son los 3 grupos de pa-cientes en situaciones clínicas definidas como comple-jas. Coo medida del riesgo se estudian las ¿Odds Ra-tio¿ (OR). Resultados: Se estudian 511 pacientes con 8.015 NP. 283 resultaron incluidos en una o más de las 3 situacio-nes clínicas complejas. Los tres grupos presentaron ni-veles de mortalidad e hipoalbuminemia superiores con diferencias estadísticamente significativas sobre el grupo de situación clínica no compleja. La utilización de fórmulas individualizadas fue superior en los tres grupos definidos resultando las diferencias estadística-mente significativas: OR = 6,7 (IC 95%; 3,78-11,91) en larga duración, OR = 3,66 (IC 95%: 2,68-5,68) en insuficiencia renal IR y OR = 1,5 (IC 95%: 1,01-2,35) en insuficiencia hepática. Conclusiones: Los pacientes en situación clínica compleja presentan mayor desnutrición visceral, peor evolución clínica y, en nuestro hospital, su tratamiento nutricional por vía parenteral se basa en una mayor utilización de fórmulas individualizadas

Summary of proceedings and expert consensus statements from the international summit "Lipids in Parenteral Nutrition"
Background: the 2018 Lipids in Parenteral Nutrition Summit involved a panel of experts in clinical nutrition, lipid metabolism, and pharmacology, to assess the current state of knowledge and develop expert consensus statements regarding the use of intravenous lipid emulsions in various patient populations and clinical settings. The main purpose of the consensus statements is to assist healthcare professionals by providing practical guidance on common clinical questions related to the provision of lipid emulsions as part of parenteral nutrition.Methods: the summit was designed to allow interactive discussion and consensus development. The resulting consensus statements represent the collective opinion of the members of the expert panel, which was informed and supported by scientific evidence and clinical experience.Results: the current article summarizes the key discussion topics from the summit and provides a set of consensus statements designed to complement existing evidence-based guidelines. Lipid emulsions are a major component of parenteral nutrition, serving as a condensed source of energy and essential fatty acids. In addition, lipids modulate a variety of biologic functions, including inflammatory and immune responses, coagulation, and cell signaling. A growing body of evidence suggests that lipid emulsions containing omega-3 fatty acids from fish oil confer important clinical benefits via suppression of inflammatory mediators and activation of pathways involved in the resolution of inflammation.Conclusions: this article provides a set of expert consensus statements to complement formal parenteral nutrition guideline recommendations
Multicenter study of parenteral nutrition in non-critically ill elderly patients compared to younger patients - Study IAIOS-PN (Incidence and Assessment of Iatrogenesis in Older Subjects receiving Parenteral Nutrition)
OBJECTIVE: this study assessed the incidence of hyperglycemia, hypertriglyceridemia, and liver function test (LFT) alterations among patients older and younger than 65 years receiving parenteral nutrition (PN). A secondary objective was to compare the incidence of any of these three events. MATERIAL AND METHODS: inclusion criteria were non-critically ill adult inpatients receiving PN for ≥ 7 days in 15 hospitals in Spain. Exclusion criteria were hyperglycemia, hypertriglyceridemia, LFT alterations, sepsis, shock, pancreatic/hepatobiliary surgery, renal failure, diabetes mellitus (DM) type 1, insulin-treated DM type 2, acute DM complications, or obesity prior to PN. Patients were classified into groups YOUNG (aged 35-64) and OLD (aged 65-95). RESULTS: this study recruited 200 patients. Group YOUNG included 63 (31.5%) patients and OLD, 137 (68.5%). Hyperglycemia appeared in 37 (18.5%) patients, eight (12.7%) in group YOUNG and 29 (21.2%) in group OLD (p = 0.174). Hypertriglyceridemia appeared in only one (0.7%) patient. LFT alterations appeared in 141 (70.5%) patients, 44 (69.8%) in group YOUNG and 97 (70.8%) in group OLD (p = 1.000). The model for hyperglycemia included DM type 2, previous surgical procedure, and use of hyperglycemia-inducing medications. The model for LFT alteration included previous surgical procedure, amount of lipids and amino acids, medications causing LFT alterations and a trend for age group. The model for any event included surgical procedure, DM type 2, and medications causing alterations. CONCLUSION: patients of ≥ 65 years receiving PN had similar incidences of hyperglycemia, hypertriglyceridemia, and LFT alterations as younger patients. Additionally, older patients had trends toward lower LFT alterations
