RESUMEN
BACKGROUND: Short bowel syndrome is considered a low prevalence disease. The scant information available about intestinal failure in Latin America was the driving force to expand this registry. METHODS: A prospective, multicenter observational registry was created for patients with chronic intestinal failure short bowel at specialized centers in Latin America. Demographics, clinical characteristics, nutrition assessment, parenteral nutrition management, intestinal rehabilitation, related complications, clinical outcome, and survival were analyzed. RESULTS: From May 2020 to July 2023, 167 patients (115 adults, 52 children) from 20 centers were enrolled. For the adults, the mean age was 37.2 ± 18 years, 48% were female, and the mean follow-up was 22.6 ± 18.3 months. The main etiology was surgical resections (postsurgical complications: 37%; ischemia: 25%); the mean intestinal length was 73 ± 55 cm. The complications were as follows: infections: 0.4/1000 catheter-days; thrombosis: 0.24/1000 catheter-days; liver disease: 2.6%. The outcomes were as follows: 28% were rehabilitated, 15% died, 9.6% were lost to follow-up, 0.9% underwent transplant, and 45.6% continued follow-up. For the children, the mean age 48 ± 52 months, 48% were female, 52% were premature. The mean follow-up was 17.2 ± 5.6 months; the mean remaining intestinal length was 38 ± 45 cm. The leading etiologies were atresia (25%), NEC (23%), and gastroschisis (21%). The complication were as follows: infections: 2/1000 catheter-days; thrombosis: 2.22/1000 catheter-day; 25% developed liver disease. The outcomes were as follows: 7.7% died, 3.8% were rehabilitated, and 88.5% continued follow-up. CONCLUSION: The RESTORE amendment served as a registry and educational tool for the participating teams. The aspiration is to objectively show current aspects of intestinal failure in the region and carry them to international standards. Including all Latin American countries and etiologies of chronic intestinal failure besides short gut would serve to complete this registry.

BACKGROUND AND AIMS: Correctly characterizing malnutrition is a challenge. Transthyretin (TTR) rapidly responds to adequate protein intake/infusion, which could be used as a marker to identify malnutrition. Nutritional therapy is used to prevent malnutrition. Parenteral nutrition (PN) requires daily monitoring to determine whether what is being offered is adequate. This article aims to investigate whether the practice of measuring TTR is justified. METHODS: Data from patients admitted to the ward or intensive care unit (ICU) were collected at three different times: within the first 72 h (T1) of PN use, on the 7th day (T2), and the 14th day (T3) after the initial assessment. RESULTS: 302 patients were included; the average age was 48.3 years old; the prevalence of death was 22.2%, and 61.6% of the sample were male. TTR values and the effectiveness of nutritional support in these patients were not associated with the outcome; however, meeting caloric needs was related to the outcome (p = 0.047). No association was found when TTR values were compared to the nutritional status. Thus, TTR was not a good indicator of nutritional risk or nutritional status in hospitalized patients. CONCLUSIONS: Undoubtedly, the TTR measurement was inversely proportional to CRP measurements. It was possible to conclude in this follow-up cohort of hospitalized patients that TTR values were not useful for determining whether the patient was malnourished, predicting death or effectiveness of nutritional support, yet based upon our analyses, a decrease in TTR greater than 0.024 units for every 1 unit increase in CRP might be due to ineffective nutritional supply.

OBJECTIVE: This study aimed to verify the dietary adequacy of full enteral feeding in preterm newborns (PTNB) and its relationship with birth weight (BW) during the period of hospitalization in the neonatal intensive care unit (NICU). METHODS: This is a prospective cohort study whose population were babies born at less than 37 gestational weeks and weighing less than 2500 g, admitted to a NICU. PTNB were monitored regarding their dietary evolution, considering parenteral and enteral nutrition and adequacy of diet supply in terms of volume, energy, and protein. For statistical analysis, the Statistical Package for the Social Sciences (SPSS) software was used, considering p < 0.05 as significant. RESULTS: A total of 76 PTNB were included. The mean time of using parenteral nutrition was 14 days. The mean time to reach the full enteral feeding for nutrition (FEF-N) was 29 days. However, half of the PTNB reached nutritional recommendations after this means. The time to achieve FEF-N was influenced by BW. Additionally, BW significantly influenced the length of stay in the NICU (p < 0.001). When reaching the recommended full enteral feeding for hydration (FEF-H), 60% of the sample was unable to reach the recommended energy and protein intake. CONCLUSIONS: BW influenced the time needed to reach the FEF-H and FEF-N. The lower the BW, the longer it took to achieve dietary adequacy. Despite achieving the FEF-H, most premature babies did not reach the necessary energy and protein intake at the appropriate time.

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.

OBJECTIVE: Endogenous melatonin is produced from tryptophan which is an essential amino acid. Besides its role in the regulation of sleep patterns, melatonin has anti-inflammatory effects. In this case-control study, we aimed to compare tryptophan and melatonin levels and their relationship with the inflammatory response, specifically serum interleukin-1, interleukin-6, and c-reactive protein levels following major abdominal surgery in patients with food restriction and who receive parenteral nutritional therapy. METHODS: We enrolled 40 patients between the ages of 18 and 65 years in the study. We collected blood and urine samples 48 h before the operation and on postoperative days 1, 3, and 5. RESULTS AND CONCLUSION: The tryptophan levels in the experimental group were higher than in the control group but failed to reach any statistical difference. Melatonin levels were increased in both groups following the surgery compared with preoperative levels. The increase in the experimental group was statistically different 3 days after the surgery. The difference in the level of interleukin-1 between the control and the experimental groups was greatest on postoperative day 3. On postoperative day 3, the interleukin-6 level in the treatment group was slightly higher than in the control group. We did not find any difference in the levels of c-reactive protein between the groups. As a result, the levels of tryptophan and melatonin were increased in the parenteral nutrition group, irrespective of the postoperative inflammatory response.

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.
Introducción. La enfermedad metabólica ósea de neonatos prematuros es una complicación poco común que se caracteriza por una disminución del contenido mineral en el hueso. Objetivo. Establecer la incidencia de la enfermedad metabólica ósea en neonatos prematuros y los factores de riesgo asociados. Materiales y métodos. 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.

OBJECTIVE: To compare the phase angle (PhA) through bioelectrical impedance (BIA) of children with intestinal failure (IF) using prolonged parenteral nutrition (PN) followed by an Intestinal Rehabilitation Program, with a control group. METHODS: Children under 10 years of age with IF using prolonged PN for >60 days (study group) were included. The control group consisted of healthy children without chronic pathologies, matched by sex and age. Anthropometric parameters evaluated were: weight, height, weight/age z-score (W/A), height/age z-score (H/A), BMI, BMI/A z-score, arm circumference, triceps skinfold, subscapular skinfold, mid-arm muscle circumference. BIA parameters were resistance (R), reactance (Xc), and phase angle (PhA). RESULTS: Twenty-eight children were included in the study group, median (IQR) age was 11 (8-27) months, 53.6 % were male. In the control group, 28 children were included, median (IQR) age was 12.5 (8-24.7) months, 50 % were male. Children from the study group had W/A z-scores and H/A z-scores significantly lower than controls. There was no significant difference between PhA in the study group and controls, [median (IQR) 4.3° (3.8;4.6) vs 4.0° (3.8;5.4) respectively, p = 0.980]. Prematurity was significantly higher in the study group than in the controls, but there was no significant correlation between gestational age at birth and PhA of the children from the study group. CONCLUSION: Children with IF using prolonged PN showed lower W/A and H/A compared to the control group, but without significant difference between the PhA of children with IF compared to controls.

OBJECTIVE: The present study aimed to evaluate the association between muscle mass variation, estimated by different equations, during hospitalization with the energy and protein intake and clinical and nutrition outcomes of patients using nutrition support. METHODS: A prospective observational study with patients older than 18 years in use of enteral and/or parenteral nutrition therapy and monitored by the Nutritional Therapy Committee between December 14, 2021, and December 14, 2022. Data were collected from the electronic records and were applied in 11 equations to estimate the four different portions of muscle mass of patients receiving nutrition support at the beginning and the end of hospitalization. RESULTS: A total of 261 patients were evaluated, with a median age of 61.0 (49.0-69.75) years, and 106 were women (40.6%). According to the nutrition diagnosis, several participants had severe malnutrition (39.5%). The most muscle mass estimation equations indicated a reduction of muscle mass during hospitalization. All patients presented negative energy and protein balances during hospitalization, but greater protein intake increased the lean soft tissue. Also, the greater the number of infections, metabolic complications, and scheduled diet interruption, the greater was the chance of losing muscle mass. CONCLUSION: There can be an association between the variation in muscle mass and energy and protein intake during hospitalization of patients using nutrition support. In addition, variation in muscle mass was associated with complications from nutrition support. The results emphasize the importance of anthropometric measurements to estimate muscle mass when other methods are not available.

Parenteral nutrition (PN) is commonly used in intensive care units (ICUs) and is associated with earlier hospital outcome. However, there is scarcity of information about the metabolic effects of PN caloric distribution for dogs. Considering the high tolerance of dogs to lipids and, also, that hospitalized animals usually present insulin resistance, PN formulation with high fat instead high glucose can provide metabolic benefits in this specie. This study evaluated two PN protocols, based on high lipid or high carbohydrate in 12 healthy dogs under sedation/ventilation during 24 h. For baseline data, blood samples were collected 24 h before the study beginning. After fasting, the dogs were anesthetized and put under mechanical ventilation without energy support for 12 h to obtain: daily energy expenditure (DEE), respiratory quotient (RQ), oxygen consumption (VO2), carbon dioxide production (VCO2), lactate, glucose, cholesterol, and triglycerides concentrations. After, the dogs were allocated into two groups: lipid-based energy group (LEG) and carbohydrate-based energy group (CEG). Both groups received the PN infusions at a rate of 3 mL/kg/h for 12 h. Blood tests were performed 12, 24, and 48 h after infusion's completion. VO2 increased after PN in LEG, increasing energy expenditure compared to CEG. RQ remained close to 1 in CEG, indicating carbohydrate preferential consumption. Triglycerides increased in both groups after propofol infusion, remaining higher in LEG until the end of the evaluation. Glycaemia increased in CEG compared to baseline. In conclusion, both PN protocols can be used in healthy animals undergoing prolonged sedation protocols. However, high lipid PN had higher VO2 and DEE, and resulted in higher triglycerides concentrations and lower glycaemia indexes than carbohydrate, making high carbohydrate PN preferable to high lipid PN. Therefore, for use in critically ill patients, the data obtained in this study should be extrapolated, taking into consideration the specificity of each case.

Nutritional support in adult patients receiving extracorporeal membrane oxygenation (ECMO) therapy is controversial. Although there are guidelines for the NS (Nutritional support) in pediatric patients with ECMO, in adults these guidelines are not available for the use, type, route and timing of nutritional therapy. In critically ill patients it is well known that early enteral nutrition is beneficial, however there is the possibility that in patients with ECMO early enteral nutrition leads to gastrointestinal complications. Likewise, there have not been established caloric targets, proteins and doses or types of micronutrients to use for this specific population being a challenge for the clinician. In addition, patients with ECMO are some of the most seriously ill in intensive care units, where malnutrition is associated with increased morbidity and mortality. Regarding the use of parenteral nutrition (NP) it has not been described if it implies a risk of circuit failure at the time of introducing lipids to the oxygenator. Therefore, a correct evaluation and specific nutritional intervention by experts in the field is imperative to improve the prognosis and quality of life in this population, which is a primary goal in the care of adult patients receiving extracorporeal membrane oxygen.
El soporte nutricional (SN) en pacientes adultos que reciben terapia de oxigenación por membrana extracorpórea (ECMO, extracorporeal membrane oxygenation) es controvertido. Si bien existen guías para el SN en pacientes pediátricos con ECMO, en adultos no se cuenta con estos lineamientos para el uso, tipo, ruta y momento de la terapia nutricional. En pacientes críticamente enfermos es bien sabido que la nutrición enteral (NE) temprana es beneficiosa, no obstante existe la posibilidad de que en pacientes con ECMO la NE temprana condicione complicaciones gastrointestinales. Asimismo, no se han establecido metas calóricas, proteicas y dosis o tipos de micronutrimentos que usar para esta población en específico, siendo un reto para el clínico encargado de brindar el SN. Aunado a esto los pacientes con ECMO son algunos de los más gravemente enfermos en las unidades de cuidados intensivos, donde la desnutrición se asocia con una mayor morbilidad y mortalidad. En cuanto al uso de nutrición parenteral (NP), no se tiene descrito si implica riesgo de falla en el circuito al momento de introducir lípidos al oxigenador. Por lo anterior es imperativa una correcta evaluación e intervención nutricional específica, realizada por expertos en el tema para mejorar el pronóstico y la calidad de vida en esta población, siendo un objetivo primordial en los cuidados de los pacientes adultos que reciben terapia de ECMO.

OBJECTIVE: We aimed to assess the evidence on the efficacy and safety of transanastomotic feeding tubes (TAFTs) in neonates with congenital duodenal obstruction (CDO), we conducted a systematic review. MATERIAL AND METHODS: Using the databases EMBASE, PubMed, and Cochrane, we carried out a thorough literature search up to 2022. Studies comparing TAFT + and TAFT - for CDO were included. We applied a random effect model. RESULTS: 505 CDO patients who met the inclusion criteria were selected. The TAFT + group had a shorter time to reach full feeds (weighted mean difference [WMD]: -6.63, 95% confidence interval [CI]: -8.83 - -4.43; p < 0.001) and had significantly less central venous catheter (CVC) insertion (I2 = 85%) (RR: 0.43, 95% CI: 0.19-1.00; p < 0.05). Fewer patients in the TAFT + group received parenteral nutrition (PN) (I2 = 78%) (RR: 0.43, 95% CI: 0.20-0.95; p < 0.05). There was no statistically significant difference in terms of the development of sepsis (I2 = 37%) (risk ratio [RR]: 1.35, 95% CI: 0.52-3.46; p > 0.05). No statistically significant difference was observed in terms of length of stay (I2 = 82%) (WMD: 2.22, 95% CI: -7.59-12.03; p > 0.05) and mortality (I2 = 0%) (RR: 0.55, 95% CI: 0.07-4.34; p > 0.05). CONCLUSIONS: The use of the transanastomotic tube resulted in early initiation of full feeding, less CVC insertion, and less need for PN.
OBJETIVO: Nuestro objetivo fue evaluar la evidencia sobre la eficacia y seguridad de TAFT en recién nacidos con CDO, realizamos una revisión sistemática. MATERIAL Y MÉTODOS: Utilizando las bases de datos EMBASE, PubMed y Cochrane, realizamos una búsqueda bibliográfica exhaustiva hasta 2022. Se incluyeron estudios que compararan TAFT + y TAFT - para CDO. Aplicamos un modelo de efectos aleatorios. RESULTADOS: Se seleccionaron 505 pacientes con ODC que cumplían con los criterios de inclusión. El grupo TAFT + tuvo un tiempo más corto para alcanzar la alimentación completa (DMP -6.63, IC del 95 %: −8.83 a −4.43; p < 0.001) y tuvo una inserción de CVC significativamente menor. Menos pacientes en grupo TAFT + recibieron NP (I2 = 78%) (RR: 0.43, IC del 95%: 0.20 a 0.95; p < 0.05). No hubo diferencia estadísticamente significativa en cuanto al desarrollo de sepsis. No se observaron diferencias estadísticamente significativas en cuanto a la duración de la estancia (I2 = 82 %) (DMP 2.22, IC del 95 %: −7.59 a 12.03; p < 0.05) y mortalidad (I2=0 %) (RR: 0.55, IC del 95 % 0.07 a 4.34; p > 0.05). CONCLUSIONES: El uso de la sonda transanastomótica resultó en el inicio temprano de la alimentación completa, menor inserción de CVC y menor necesidad de NP.

PURPOSE: Parenteral nutrition (PN) has been shown to be a safe method of feeding in the intensive care unit with modern infection prevention practices, but similar analysis in the hematology-oncology setting is lacking. METHODS: A retrospective analysis of 1,617 patients with hematologic malignancies admitted and discharged from the Hospital of the University of Pennsylvania during 3,629 encounters from 2017 to 2019 was undertaken to evaluate the association of PN administration with risk of central line-associated bloodstream infection (CLABSI). Proportions of mucosal barrier injury (MBI)-CLABSI and non-MBI-CLABSI were also compared between groups. RESULTS: Risk of CLABSI was associated with cancer type and duration of neutropenia but not with PN administration (odds ratio, 1.015; 95% CI, 0.986 to 1.045; P = .305) in a multivariable analysis. MBI-CLABSI comprised 73% of CLABSI in patients exposed to and 70% in patients not exposed to PN, and there was no significant difference between groups (χ2 = 0.06, P = .800). CONCLUSION: PN was not associated with increased risk of CLABSI in a sample of patients with hematologic malignancy with central venous catheters when adjusting for cancer type, duration of neutropenia, and catheter days. The high proportion of MBI-CLABSI highlights the effect of gut permeability within this population.

Antecedentes: Los dispositivos de asistencia ventricular (VAD, sigla en inglés) se utilizan cada vez más para el manejo de la insuficiencia cardíaca descompensada en unidades de cuidados intensivos. El manejo nutricional es fundamental para la evolución clínica de estos pacientes. Objetivos: El objetivo fue evaluar en cuánto tiempo se puede alcanzar las necesidades nutricionales, utilizando distintas modalidades de apoyo nutricional, en pacientes que requirieron asistencia con VAD por insuficiencia cardíaca aguda en una clínica privada del país. Métodos: En una clínica privada se efectuó un estudio observacional retrospectivo analizando los datos clínicos relacionados al aporte nutricional de 12 pacientes que requirieron asistencia con VAD. Las vías de aporte nutricional evaluadas fueron la nutrición enteral (NE) y/o nutrición parenteral (NP). Se midió el tiempo de implementación del apoyo nutricional y su efecto se estimó por una valoración nutricional subjetiva y por la medición de indicadores de laboratorio. Además, se vigilaron las complicaciones asociadas al aporte nutricional. Resultados: El estudio incluyó a 12 pacientes. Los objetivos nutricionales se alcanzaron por completo en el 91% de los pacientes (n=11) en 3,7 ± 1 días después de iniciado el apoyo nutricional. En ese momento, 5 pacientes recibían NE exclusiva, 4 pacientes NP complementaria a la NE, 1 paciente NE complementaria a la alimentación oral y 1 paciente con vía oral. Al momento de alcanzar los requerimientos nutricionales ningún paciente tenía NP exclusiva. Conclusión: Concluimos que el apoyo nutricional precoz es factible y seguro en pacientes con VAD. Alcanzar los objetivos nutricionales es posible sin efectos adversos graves. Se necesitan estudios futuros para determinar el beneficio a largo plazo del apoyo nutricional agresivo para pacientes en estado crítico que requieren apoyo hemodinámico.
Background: Ventricular assist devices (VAD) are being used more frequently in patients with severe heart failure. Nutritional support is a critical factor for the outcome in these patients. Aim: to evaluate the time required and mode of nutritional support in patients with severe cardiac dysfunction being treated with VAD. Methods: 12 patients with VAD being treated in an intensive care unit were evaluated to determine the time and mode of support required to achieve adequate nutrition. Enteral and / or parenteral modes of nutritional support were used. The outcomes were evaluated by subjective appreciation, weight measurement and serum levels of albumin, pre-albumin and vitamin D. Results: Adequate nutritional support was achieved in 91% of patients a mean of 3 days after beginning of treatment (SD 1 day). At that time 5 patients were receiving only enteral nutrition, 4 patients enteral and parenteral nutrition, 1 patient enteral nutrition in addition to oral nutrition and 1 patients was receiving only oral nutrition. No patient was receiving only parenteral nutrition. Conclusion: early nutritional support is posible and safe in patients with an VAD. Further studies are needed to evaluate long term benefits of this strategy of nutritional support.

The American Society of Parenteral and Enteral Nutrition recommends nutritional risk (NR) screening in critically ill patients with Nutritional Risk Screening - 2002 (NRS-2002) ≥ 3 as NR and ≥ 5 as high NR. The present study evaluated the predictive validity of different NRS-2002 cut-off points in intensive care unit (ICU). A prospective cohort study was conducted with adult patients who were screened using the NRS-2002. Hospital and ICU length of stay (LOS), hospital and ICU mortality, and ICU readmission were evaluated as outcomes. Logistic and Cox regression analyses were performed to evaluate the prognostic value of NRS-2002, and a receiver operating characteristic curve was constructed to determine the best cut-off point for NRS-2002. 374 patients (61·9 ± 14·3 years, 51·1 % males) were included in the study. Of these, 13·1 % were classified as without NR, 48·9 % and 38·0 % were classified as NR and high NR, respectively. An NRS-2002 score of ≥ 5 was associated with prolonged hospital LOS. The best cut-off point for NRS-2002 was a score ≥ 4, which was associated with prolonged hospital LOS (OR = 2·13; 95 % CI: 1·39, 3·28), ICU readmission (OR = 2·44; 95 % CI: 1·14, 5·22), ICU (HR = 2·91; 95 % CI: 1·47, 5·78) and hospital mortality (HR = 2·01; 95 % CI: 1·24, 3·25), but not with ICU prolonged LOS (P = 0·688). NRS-2002 ≥ 4 presented the most satisfactory predictive validity and should be considered in the ICU setting. Future studies should confirm the cut-off point and its validity in predicting nutrition therapy interaction with outcomes.

BACKGROUND: Whether fasting early in critical illness course is acceptable is not clear and high-quality data on this topic are lacking. To generate equipoise for future clinical trials and bring additional data to current literature, we compared outcomes of patients fasted during the first 72 h of intensive care unit (ICU) stay to patients receiving any nutrition support during this period. METHODS: Retrospective cohort study of a medical ICU from a tertiary academic center in Brazil. Adult patients treated between November 2017 and February 2022 with an ICU length of stay of ≥5 days were included. Baseline and daily data were retrieved from the prospectively collected administrative database. We did 1:1 propensity score matching to compare patients fasting for at least 72 h with controls. Primary outcome was hospital mortality and secondary outcomes were other resources' use. RESULTS: During the study period, 1591 patients were cared for in this ICU, of which 998 stayed ≥5 days. After excluding readmissions and propensity score matching, 93 patients in the fasting group were matched to 93 controls. Hospital mortality was similar between fasting and matched control groups (odds ratio = 1.04; 95% CI = 0.56-1.94; P > 0.99). Secondary outcomes were not different between groups, including length of stay, days on mechanical ventilation, and incidence of new infections. CONCLUSION: Withholding nutrition support in the first 72 h of ICU stay was not associated with worse outcomes in this cohort of severe critically ill patients.

OBJECTIVE: The use of parenteral nutrition (PN) formulations that do not contain iodine can contribute to the deficiency of this mineral, potentially leading to hypothyroidism and, ultimately, neurocognitive impairments. This study aimed to evaluate TSH alterations in newborns receiving PN. METHODS: Retrospective study of neonatal intensive care unit patients receiving PN for > 15 days. Nutritional, anthropometric, and biochemical variables (TSH, T4, CRP) were analyzed. Hypothyroidism was defined by TSH > 10 mU/L. RESULTS: Two hundred newborns were evaluated [156 (78%) preterm, 31±5 weeks of gestational age, 112 (56%) with very or extremely low birth weight]. The median (IQR) hospital stay was 68 (42-110) days, PN duration was 31 (21-47) days, and 188 (94%) patients also received enteral nutrition. Overall, 143 (71.5%) newborns underwent at least one TSH measurement. The prevalence of hypothyroidism was 10.5%. The Median PN duration in this group was 51 (34-109) days. Among those with hypothyroidism, 10 received Lugol's solution and six levothyroxine. Thirteen patients received prophylactic Lugol's solution with a median PN duration of 63 (48-197) days. TSH levels correlated positively with PN duration (r = 0.19, p = .02). CONCLUSIONS: The present data suggest that changes in TSH and T4 levels are present in neonates receiving PN for > 15 days, suggesting this population may be at risk for developing hypothyroidism. Therefore, the authors suggest that TSH and T4 measurements should be included as routine in neonatal patients receiving PN for > 15 days if PN formulations are not supplemented with iodine, and that iodine supplementation be provided as necessary.
