- Lymphocyte count as a sign of immunoparalysis and its correlation with nutritional status in pediatric intensive care patients with sepsis: A pilot study(2016) MANZOLI, Talita Freitas; DELGADO, Artur Figueiredo; TROSTER, Eduardo Juan; CARVALHO, Werther Brunow de; ANTUNES, Ana Caroline Barreto; MARQUES, Desiree Mayara; ZAMBERLAN, PatriciaOBJECTIVES: Developing malnutrition during hospitalization is well recognized worldwide, and children are at a relatively higher risk for malnutrition than adults. Malnutrition can lead to immune dysfunction, which is associated with a higher mortality rate due to sepsis, the most frequent cause of death in pediatric intensive care units (PICUs). The aim of this study was to investigate whether malnourished patients are more likely to have relative or absolute lymphopenia and, consequently, worse prognoses. METHODS: We enrolled 14 consecutive patients with sepsis whose legal representatives provided written informed consent. Patients were classified as normal or malnourished based on anthropometric measurements. As an additional evaluation of nutritional status, serum albumin and zinc were measured on the 1 st and 7 th days of hospitalization. Lymphocyte count was also measured on the 1 st and 7 th days. Clinicaltrials. gov: NCT02698683. RESULTS: Malnutrition prevalence rates were 33.3% and 42.8% based on weight and height, respectively. Laboratory analyses revealed a reduction of serum albumin in 100% of patients and reduction of zinc in 93.3% of patients. A total of 35% of patients had fewer than 500 lymphocytes/mm(3) on their first day in the PICU. Lymphocyte counts and zinc concentrations significantly increased during hospitalization. CONCLUSIONS: Nutritional evaluations, including anthropometric measurements, were not correlated with lymphocyte counts. Lymphocyte counts concomitantly increased with zinc levels, suggesting that micronutrient supplementation benefits patients with sepsis.

Design: Survey with a questionnaire sent to Latin American Society of Pediatric Intensive Care members. Setting: PICUs of participant hospitals. Patients: Critically ill children between 1 month and 18 years old. Interventions: None. Measurements and Main Results: Forty-seven surveys from 17 countries were analyzed. Sixty-seven percent of PICUs were from university-affiliated hospitals, with a median of 380 admissions/yr. Sixty-eight percent and 48.9% had a nutritional support team and nutritional support protocol, respectively. Seventy-five percent completed nutritional evaluations, with 34.2% at admission. PICUs with high-volume admissions were likely to have a nutritional support team (p < 0.005), and university-affiliated hospitals showed a trend of having a nutritional support team (p = 0.056). Measured, estimated, and ideal weights were used in 75%, 14.6%, and 10.4%, respectively. Energy requirements were calculated using Holliday & Segar and Schofield equations in 90% of the PICUs; 43% used correction factors. Only three PICUs had indirect calorimetry. At day 3 of initiation of nutritional support, 57.3% of PICUs provided at least 50% of the calculated energy requirement, and 91.5% at day 5. Protein needs were estimated according to American Society for Parenteral and Enteral Nutrition and European Society for Clinical Nutrition and Metabolism/European Society for Paediatric Gastroenterology Hepatology and Nutrition guidelines in 55.3% and 40.4%, respectively. Enteral nutrition was the preferred feeding method, initiated in 97.7% at 48 hours. The feeding route was gastric (82.9%), by bolus (42.5%) or continuous (57.4%). Monitoring methods included gastric residual measurement in 55.3%. Enteral nutrition was discontinued in 82.8% when gastric residual was 50% of the volume. Prokinetics were used in 68%. More than half of PICUs used parenteral nutrition, with 95.8% of them within 72 hours. Parenteral nutrition was administered by central vein in 93.6%. Undernourished children received parenteral nutrition sooner, whether or not enteral nutrition intolerance was present. When enteral nutrition was not tolerated beyond 72 hours, parenteral nutrition was started in 57.4%. Parenteral nutrition was initiated when enteral nutrition delivered less than 50% in 97%. Conclusions: Nutritional practices are heterogeneous in Latin American PICUs, but the majority use nutritional support strategies consistent with international guidelines.
conferenceObject Nutritional Status Deterioration of Children with Cancer in the First Week of Intensive Care and Relation to Clinical Outcomes(2018) VIANI, K.; RAFAEL, M. Neto; PUGLIESE, C.; MIGUEL, G. Bouchabki; MANZOLI, B. Stachissini; ZAMBERLAN, P.- Nutrition Therapy in a Pediatric Intensive Care Unit: Indications, Monitoring, and Complications(2011) ZAMBERLAN, Patricia; DELGADO, Artur Figueiredo; LEONE, Claudio; FEFERBAUM, Rubens; OKAY, Thelma SuelyBackground: Nutrition therapy (NT) is essential for the care of critically ill children. Inadequate feeding leads to malnutrition and may increase the patient's risk of morbidity and mortality. The aim of this study was to describe the NT used in a tertiary pediatric intensive care unit (PICU). Methods: The authors evaluated NT administered to 90 consecutive patients who were hospitalized for 7 days in the PICU of Instituto da Crianca, Hospital das Clinicas, Universidade de Sao Paulo, Brazil. NT was established according to the protocol provided by the institution's NT team. NT provided a balance of fluids and nutrients and was monitored with a weekly anthropometric nutrition assessment and an evaluation of complications. Results: NT was initiated, on average, within 72 hours of hospitalization. Most children (80%) received enteral nutrition (EN) therapy; of these, 35% were fed orally and the rest via nasogastric or postpyloric tube. There were gastrointestinal complications in patients (5%) who needed a postpyloric tube. Parenteral nutrition (PN) was used in only 10% of the cases, and the remaining 10% received mixed NT (EN + PN). The average calorie and protein intake was 82 kcal/kg and 2.7 g/kg per day. Arm circumference and triceps skinfold thickness decreased. Conclusions: The use of EN was prevalent in the tertiary PICU, and few clinical complications occurred. There was no statistically significant change in most anthropometric indicators evaluated during hospitalization, which suggests that NT probably helped patients maintain their nutrition status.

- Bioelectrical Impedance Phase Angle and Morbidity and Mortality in Critically Ill Children(2019) ZAMBERLAN, Patricia; FEFERBAUM, Rubens; DORIA FILHO, Ulysses; CARVALHO, Werther Brunow de; DELGADO, Artur FigueiredoBackgroundNutrition markers may be useful for diagnosis and monitoring and, also, as additional indicators of estimating death risk. We tested the association of body composition indicators (mid-upper arm circumference and phase angle) with pediatric intensive care unit (PICU) length of stay and mortality in critically ill pediatric patients. MethodsData from children aged 2 months-18 years were collected, and bioelectrical impedance was performed to obtain phase angle. Severity was evaluated by scoring the Pediatric Index of Mortality. Descriptive statistics were reported for nominal variables. Receiver operating characteristic curve was used to analyze the association of phase angle with 30-day mortality and to find the best cutoff. Survival probabilities and PICU length of stay were estimated using the Kaplan-Meier method. ResultsWe evaluated 247 children with a median age of 4.8 years whose main cause of admission was sepsis. Survival curves showed higher survival in patients with phase angle >2.8 degrees compared with patients with phase angle 2.8 degrees (P<.0001). Kaplan-Meier time-to-event analysis showed that children with lower phase angle values were more likely to remain in the PICU (hazard ratio, 1.84; P=.003). Lower survival was also observed in patients who presented mid-upper arm circumference values 5th percentile (P<.03). ConclusionsMid-upper arm circumference and phase angle were associated with mortality and morbidity in critically ill children, suggesting that these parameters may be useful not only for nutrition diagnosis and monitoring, but also as an additional indicator in estimating prognosis.

- Influence of Shortened Fasting Time on Perioperative Outcomes in Pediatric Patients: A Systematic Review(2024) MATA, Amanda Michelly Braga da; TOMAZ, Ane Gabriele do Carmo; CUNHA, Gabriella Cristina Andrade da; ZAMBERLAN, Patricia; BONFIM, Maria Aparecida CarlosBackground: Prolonged preoperative fasting can cause hypoglycemia, dehydration, hypotension, and irritability, especially in children. Multimodal protocols such as the Enhanced Recovery After Operation (ERAS) and the Accelerated Full Postoperative Recovery (ACERTO, Acelera & ccedil;& atilde;o da Recupera & ccedil;& atilde;o Total P & oacute;s-Operat & oacute;ria) recommend a shortened fasting period. The aim of this study is to evaluate the association between shortened preoperative fasting and perioperative outcomes in pediatric patients. Methods: This study is a systematic review of the literature. The inclusion criteria were original studies published between January 2017-November 2022 that used shortened preoperative fasting protocols validated in patients aged 0-17 years and that evaluated the association of this practice with perioperative outcomes. The studies were obtained from the Latin American and Caribbean Literature on Health Sciences (LILACS), National Library of Medicine and National Institutes of Health (PubMed) and Science Direct databases. Results: A total of 6064 articles were obtained, of which eight were considered eligible. The results showed that shortened preoperative fast is safe in children and adolescents. The main benefits of this practice were higher preoperative blood glucose, no episodes of preoperative hypoglycemia, lower incidence of nausea, and minor complaints of crying. Conclusions: Shortening the fasting time with high-carbohydrate drinks between one and 2 h before operation is safe in children and adolescents, being associated with better metabolic and emotional responses in the perioperative period.
