bookPart Suporte nutricional em crianças criticamente enfermas(2023) CARDOSO, Ary Lopes; TUMAS, Rosana; ZAMBERLAN, Patricia; GANDOLFO, Adriana Servilha- Malnutrition and Nutrition Support in Latin American PICUs: The Nutrition in PICU (NutriPIC) Study(2023) CAMPOS-MINO, Santiago; FIGUEIREDO-DELGADO, Artur; ZARATE, Patricia; ZAMBERLAN, Patricia; MUNOZ-BENAVIDES, Eliana; COSS-BU, Jorge A.OBJECTIVES: To characterize the nutritional status of children admitted to Latin American (LA) PICUs and to describe the adequacy of nutrition support in reference to contemporary international recommendations. DESIGN: The Nutrition in PICU (NutriPIC) study was a combined point-prevalence study of malnutrition carried out on 1 day in 2021 (Monday 8 November) and a retrospective cohort study of adequacy of nutritional support in the week preceding. SETTING: Four-one PICUs in 13 LA countries. PATIENTS: Patients already admitted to the PICU of 1 month to 18 years old on the study day were included in the point-prevalence study. For the retrospective arm, we included patients receiving nutritional support on the study day and with a PICU length of stay (LOS) greater than or equal to 72 hours. Exclusion criteria were being a neonate, conditions that precluded accurate anthropometric measurements, and PICU LOS greater than 14 days. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Of 316 patients screened, 5 did not meet age criteria. There were 191 of 311 patients who were included in the point-prevalence study and underwent anthropometric evaluation. Underweight and length for age less than -2 z scores were present in 42 of 88 children (47.7%) and 41 of 88 children (46.6%) less than 24 months old, and 14 of 103 (13.6%) and (23/103) 22.3% of 103 children greater than or equal to 24 months, respectively. Evidence of obesity (body mass index > 2 z score) was present in 7 of 88 children (5.7%) less than 24 months old and 13 of 103 children (12.6%) greater than or equal to 24 months. In the 115 of 311 patients meeting criteria for the retrospective arm, a total of 98 patients reported complete nutritional data. The 7-day median (interquartile range) adequacy for delivered versus recommended enteral energy and protein requirement was 114% (75, 154) and 99% (60, 133), respectively. CONCLUSIONS: The NutriPIC study found that in 2021 malnutrition was highly prevalent especially in PICU admissions of less than 24 months old. Retrospectively, the 7-day median nutritional support appears to meet both energy and protein requirements.
- Body composition in pediatric patients(2023) ZAMBERLAN, Patricia; MAZZONI, Beatriz P.; BONFIM, Maria A. C.; VIEIRA, Rafaela R.; TUMAS, Rosana; DELGADO, Artur F.Undernutrition is highly prevalent in children who are critically ill and is associated with increased morbidity and mortality, including a higher risk of infection due to transitory immunological disorders, inadequate wound healing, reduced gut function, longer dependency on mechanical ventilation, and longer hospital stays compared with eutrophic children who are critically ill. Nutrition care studies have proposed that early interventions targeting nutrition assessment can prevent or minimize the complications of undernutrition. Stress promotes an acute inflammatory response mediated by cytokines, resulting in increased basal metabolism and nitrogen excretion and leading to muscle loss and changes in body composition. Therefore, the inclusion of body composition assessment is important in the evaluation of these patients because, in addition to the nutrition aspect, body composition seems to predict clinical prognosis. Several techniques can be used to assess body composition, such as arm measurements, calf circumference, grip strength, bioelectrical impedance analysis, and imaging examinations, including computed tomography and dual-energy x-ray absorptiometry. This review of available evidence suggests that arm measurements seem to be well-established in assessing body composition in children who are critically ill, and that bioelectrical impedance analysis with phase angle, handgrip strength, calf circumference and ultrasound seem to be promising in this evaluation. However, further robust studies based on scientific evidence are necessary.
