RESUMEN
This study aimed to evaluate the incidence and risk factors associated with refeeding syndrome (RFS) in preterm infants (≤32 weeks gestational age) during their first week of life. Infants (gestational age ≤ 32 weeks; birth weight < 1500 g) who were admitted to the neonatal intensive care unit (NICU), level III, and received parenteral nutrition between January 2015 and April 2024 were retrospectively evaluated. Modified log-Poisson regression with generalized linear models and a robust variance estimator was applied to adjust the relative risk of risk factors. Of the 760 infants identified, 289 (38%) developed RFS. In the multivariable regression analysis, male, intraventricular hemorrhage (IVH), and sodium phosphate significantly affected RFS. Male infants had significantly increased RFS risk (aRR1.31; 95% CI 1.08-1.59). The RFS risk was significantly higher in infants with IVH (aRR 1.71; 95% CI 1.27-2.13). However, infants who received higher sodium phosphate in their first week of life had significantly lower RFS risk (aRR 0.67; 95% 0.47-0.98). This study revealed a notable incidence of RFS among preterm infants aged ≤32 gestational weeks, with sex, IVH, and low sodium phosphate as significant risk factors. Refined RFS diagnostic criteria and targeted interventions are needed for optimal management.

BACKGROUND: Patients receiving parenteral nutrition (PN) may develop refeeding syndrome (RFS). This study determined RFS prevalence in hospitalized adults on PN and evaluated whether higher energy delivered by PN on day 1 of PN initiation was associated with RFS development. METHODS: We reviewed the medical records of adult patients receiving PN at a Thai quaternary hospital from June 2019 to May 2022. RFS was defined based on the Nutrition Management Clinical Practice Recommendation by the Society of Parenteral and Enteral Nutrition of Thailand. The association between PN energy delivery and RFS development was determined using a generalized estimating equation for multiple logistic regression analysis adjusted for NICE guideline risk factors. RESULTS: A total of 547 patients was included (mean age 59.8 ± 17.2 years, mean body mass index 20.7 ± 4.8 ). The prevalence of RFS was 45%. Factors associated with RFS included energy from PN on the first day of PN initiation (adjusted odds ratio [aOR] 1.17; 95% CI 1.04-1.33; for every 5 kcal/kg/day increase), starvation >5 days prior to PN (aOR 1.54; 95% CI 1.04-2.26), concomitant diuretic use (aOR 1.81; 95% CI 1.25-2.64), low baseline potassium level (aOR 1.79; 95% CI 1.19-2.70), and individual compounding PN (aOR 1.61; 95% CI 1.04-2.51). CONCLUSION: RFS was common among hospitalized patients receiving PN. The amount of energy delivered on the first day of PN was independently associated with RFS, raising a concern regarding initiation of PN with higher energy.

OBJECTIVE: To describe the incidence of hypophosphatemia in patients admitted to the ICU who have required mechanical ventilation. To analyze the presence of risk factors and its relationship with nutritional practice. DESIGN: Prospective observational study. SETTING: Polyvalent ICUs of 2 University Hospitals. PATIENTS OR PARTICIPANTS: Patients on invasive mechanical ventilation ≥72â¯h with normal level of phosphorus at admission. INTERVENTIONS: None. MAIN VARIABLES OF INTEREST: Electrolyte levels (phosphorus, magnesium, potassium) were determined on admission to the ICU and at 96â¯h. Risk categories on admission, caloric intake, insulin doses and acid-base status during the first 4 days of admission were recorded. Incidence was calculated as the number of patients who developed hypophosphataemia after admission. Univariate analysis was performed for between-group comparison and multivariate analysis of potential risk factors. RESULTS: 89 patients were included. The incidence of hypophosphataemia was 32.6%. In these patients phosphorus decreased from 3.57⯱â¯1.02â¯mmol/l to 1.87⯱â¯0.65â¯mmol/l (52.3%). The mean kcal/kg/24â¯h provided in the first 4 days was 17.4⯱â¯4.1, with no difference between the group that developed hypophosphataemia and the group that did not. Significant risk factors were insulin doses administered and pH and PaCO2 values. CONCLUSIONS: The incidence of hypophosphataemia at 96â¯h from admission in mechanically ventilated patients is high and unrelated to the risk category and hypocaloric nutritional practice used. Insulin dosis and acid-base status are the main determinants of its occurrence.

OBJECTIVE: Nutritional rehabilitation and weight restoration are often critical for the treatment of eating disorders (ED), yet are restricted by the potential risk of refeeding syndrome (RFS). The primary objective was to determine the incidence of RFS. Secondary objectives were to explore predictive factors of RFS and describe its impact on treatment goals for patients with ED. METHOD: This retrospective observational study reviewed the nutrition management for patients admitted to a quaternary hospital for ED treatment from 2018 to 2020. Data were collected during the first 4 weeks of admission and included anthropometry, energy prescription, incidence and severity of RFS, and electrolyte and micronutrient prescription. Outcomes included incidence of RFS, energy prescription and advancement, and weight change. RESULTS: Of 423 ED admissions, 217 patients (median [interquartile range, IQR] age 25 [21-30.5] years; 210 [97%] female) met inclusion criteria. Median (IQR) body mass index (BMI) on admission was 15.5 (14.1-17.3) kg/m2 . The mean (standard deviation) length of admission was 35 (7.3) days. Median (IQR) initial energy prescription was 1500 (930-1500) kcal/day. Seventy-three (33%) patients developed RFS; 34 (16%) mild, 27 (12%) moderate, and 12 (5%) severe. There was no association between RFS severity and admission BMI, energy prescription, or prescription of prophylactic electrolytes or micronutrients. Lower admission weight was associated with RFS (odds ratio 0.96, 95% confidence interval [0.93-1.00], p = .035). Less than half of the participants met the weight gain target (>1 kg per week) in the first 3 weeks of admission. DISCUSSION: The incidence of severe RFS was low in this cohort and was associated with lower admission weight. PUBLIC SIGNIFICANCE: This study is one of the largest studies to utilize consensus-defined criteria to diagnose RFS among adult patients admitted for treatment of an ED. This population is still considered to be at risk of RFS and will require close monitoring. The results add to the growing body of research that restriction of energy prescription to prevent RFS may not require the level of conservatism traditionally practiced.

Introduction: starvation is usual in patients referred for endoscopic gastrostomy (PEG). A high risk of refeeding syndrome (RS) may contribute to poor prognosis. Objectives: this study aims to: a) evaluate serum phosphorus and magnesium when patients underwent PEG; b) determine the mortality rate during the first week and first month of enteral nutrition; and c) assess if hypophosphatemia or hypomagnesemia are associated with early mortality. Material and methods: retrospective study with patients followed in the Artificial Nutrition Clinic and died under PEG feeding. General nutritional assessment included NRS 2002, anthropometry and serum proteins. Serum phosphorus and magnesium were measured immediately before gastrostomy. Survival was recorded and compared to electrolyte and nutritional status. Results: one hundred and ninety-seven patients (137 men/60 women) aged 26-100 years. Most underwent PEG due to neurologic disorders (60.9%) and were malnourished according to body mass index (BMI) and serum proteins. Low phosphorus and magnesium were found in 6.6% and 4.6%, respectively. Hypophosphatemia was associated with malnutrition (p < 0.05). Mean survival was 13.7 ± 15.4 months. Mortality was 4.6% in the first week and 13.2% in the first month post-gastrostomy. Overall survival was shorter in malnourished patients but malnutrition did not directly influence early mortality (p > 0.05). Hypophosphatemia was associated with mortality during the first week (p = 0.02) and the first month of PEG feeding (p = 0.02). Conclusions: hypophosphatemia was uncommon but predicted early mortality after PEG. Although RS may be less frequent than expected, hypophosphatemia may be used as a RS marker and RS is the probable cause of increase early mortality in hypophosphatemic PEG-fed patients
Introducción: la inanición es habitual en pacientes referenciados para gastrostomía endoscópica (PEG). Un riesgo alto de síndrome de realimentación (SR) puede contribuir a un mal pronóstico. Objetivos: este estudio pretende: a) estudiar el fósforo y el magnesio séricos cuando los pacientes son sometidos a PEG; b) determinar la tasa de mortalidad durante la primera semana y el primer mes de nutrición entérica; y c) evaluar si la hipofosfatemia y la hipomagnesemia se asocian con una mortalidad temprana. Material y métodos: estudio retrospectivo con pacientes seguidos en la consulta de nutrición artificial y que fallecieron utilizando alimentación por PEG. La evaluación nutricional genérica ha incluido el NRS 2002, la antropometría y la determinación de las proteínas séricas. El fósforo y el magnesio séricos se han determinado inmediatamente antes de la gastrostomía. La sobrevida fue registrada y comparada con el perfil iónico y el estado nutricional de los pacientes. Resultados: el estudio se realizó en 197 pacientes (137 hombres/60 mujeres) de 26-100 años. La mayoría se sometieron a PEG por trastornos neurológicos (60,9%) y estaban desnutridos de acuerdo con el índice de masa corporal (IMC) y las proteínas séricas. El fósforo y el magnesio séricos estaban bajos, con un 6,6% y un 4,6%, respectivamente. La hipofosfatemia se asoció con la desnutrición (p < 0,05). La sobrevida media fue de 13,7 ± 15,4 meses. Se ha registrado una mortalidad del 4,6% en la primera semana y del 13,2% en el primer mes después de la gastrostomía. La sobrevida general fue más corta en los pacientes desnutridos, pero la desnutrición no ha afectado directamente a la mortalidad temprana (p > 0,05). La hipofosfatemia se asoció con la mortalidad durante la primera semana (p = 0,02) y el primer mes de alimentación con PEG (p = 0,02). Conclusiones: la hipofosfatemia fue infrecuente, pero predijo una mortalidad temprana después del PEG. Aunque el SR es aparentemente menos frecuente de lo esperado, la hipofosfatemia puede ser utilizada como un marcador del SR y el SR es probablemente la causa de una mortalidad temprana en pacientes hipofosfatémicos alimentados con PE
