ABSTRACT
Introduction: To assess the use of nutritional support in children and adolescents submitted to autologous hematopoietic stem cell transplantation (HSCT), and analyze changes in nutritional status at hospital discharge after HSCT. Methods: A retrospective observational study was conducted on pediatric oncology patients hospitalized for autologous HSCT between 2010 and 2017. Nutritional therapy was evaluated based on the duration of enteral tube feeding (ETF) and parenteral nutrition (PN), either alone or in combination. The length of hospital stay was measured in days. Nutritional status was assessed at admission and discharge, and classified according to World Health Organization criteria. Results: The sample consisted of 68 patients, 54.4% of whom were boys. Most participants (89.7%) had solid tumors. Nutritional therapy was required in over half (52.9%) of cases, with PN being the most common indication. There was a reduction in the percentage of overweight patients and an increase in the percentage of underweight patients at discharge relative to admission. Conclusions: The use of nutritional therapy is highly prevalent in this population, and HSCT has a negative impact on nutritional status at discharge. (AU)

Objective To establish a reference range of cancellous bone ultrasonic backscatter coefficient (BSC) in term neonates,and to determine the significance of BSC in bone nutritional status in term newborns and infants.Methods Six hundred and sixty-five term newborns,who were born in Shanghai First Maternity and Infant Hospital from July 2014 to August 2014,were enrolled.On the third day and the 42nd day after birth,all infants underwent ultrasonic measurement of the calcaneum bone using a broadband-non-focus ultrasonic transducer at three frequencies (2.25,3.5 and 5 MHz).MATLAB software was used to analyze the backscatter signals.Clinical data of the infants,including gestational age,birth weight and birth age,were recorded at the same time.Statistical analyses of the data included variance analysis,Tukey's test,rank sum test,Dunn test and Pearson or Spearman correlation analysis.Results (1) Of the 665 infants,335 were male.The mean gestational age at birth was (38.0± 1.9) weeks,and the mean birth weight was (3 1524±226) g.(2) On the third day,there were significant differences in BSC values acquired at 2.25 and 3.5 MHz among the groups with different gestational ages or birth weights (2.25 MHz:H=9.842 and 17.271;3.5 MHz:H=6.275 and 21.450,respectively,all P<0.05).At 3.5 and 2.25 MHz,BSC values were positively correlated with gestational age (r=0.047 and 0.035,respectively,both P<0.05) and birth weight (r=0.125 and 0.186,both P<0.05).(3) On the 42nd day,significant differences in BSC were observed at each frequency among the groups with different gestational ages or birth weights (gestational age:H=76.832,16.498 and 32.756;birth weight:H=70.014,18.095 and 34.126;all P<0.01).Gestational age and birth weight were positively correlated with BSC value acquired at each frequency (r=0.397,0.286 and 0.272 for gestational age,0.451,0.223 and 0.196 for birth weight;all P<0.01).Conclusions A preliminary BSC reference percentile in term-born infants is established.There are positive correlations between BSC value and newborn gestational age and birth weight at certain frequencies,which can reflect the status of the newborn's cancellous bone.Determination of BSC value should be performed during the follow-up period to assess the nutritional status of neonatal bone.
