Objective: To investigate the long-term changes in nutritional status in children with solid tumors during treatment and the relationship between nutritional status and clinical outcomes., Methods: This study was a retrospective medical records review of data from children who were diagnosed with solid tumors and followed up for more than 3 months from January 2016 to December 2021 in China. Patient demographics and clinical information, including nutritional status, parenteral nutrition use, intensive care unit (ICU) transfers, infection during hospitalization, hospitalization frequency, length of stay, hospitalization costs and antibiotic costs, were collected to analyze the nutritional status of children with different types of solid tumors, the dynamic changes in nutritional status during treatment, and the relationship between nutritional status and clinical outcomes., Results: Among the 764 patients (383 males (50.1%); 381 females (49.9%); mean age: 2.58 years), 41.6% of the solid tumors were neuroblastomas, 17.1% were hepatoblastomas, and Wilms tumors as the third most common solid tumors (8.9%). The median follow-up duration was 6 months (range: 3-40 months). At diagnosis, the proportion of children who were undernourished (underweight and wasting) versus overweight or obese were 26.71% versus 5.21% (25.86% vs. 2.89% in the third month; 29.77% vs. 2.28% in the sixth month; 24.77% vs. 3.27% in the 12th month). The body mass index Z scores decreased from the initial values after the first month (-0.56 (-1.47, 0.23) vs. -0.44 (-1.29, 0.41)) but improved later and decreased again at 6 months. The children in the undernutrition group had longer hospital stays (p < 0.001), higher hospitalization costs (p < 0.001), higher antibiotic costs (p < 0.001), a higher risk of neutropenia (OR = 4.781 (95% CI: 1.571-14.553), p = 0.006), and a higher risk of ICU transfers (OR = 1.498 (95% CI: 1.010-2.224), p = 0.044). No significant differences in those associations by malnutrition and infection, ICU duration, or length of parenteral nutrition were observed., Conclusion: There is a considerable prevalence of malnutrition in children with solid tumors. Malnutrition is related to adverse clinical outcomes and increases in total hospital expenses and antibiotic costs., (© 2023 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.)

Objective: This study aimed to assess the long-term effectiveness and seizure recurrence risk in children with drug-resistant epilepsy who achieved seizure freedom on a ketogenic diet (KD). Predictors associated with seizure recurrence were also evaluated., Methods: Patients with drug-resistant epilepsy who received KD therapy for at least 3 months between May 2011 and April 2020 were included. The clinical efficacy of the KD was evaluated. Patients who achieved seizure freedom for at least 3 months on the KD were focused. Multivariate Cox regression models were used to explore the risk factors of seizure relapse in patients who achieved seizure freedom., Results: This study included 288 patients (163 males, 125 females). The seizure-free rates of the KD at 3, 6, 12, and 24 months were 9.7%, 16.7%, 14.2%, and 9.0%, respectively. Additionally, the seizure reduction rates between 50% and 99% were 46.5%, 39.9%, 30.2%, and 20.5%, respectively. Patients with Angelman syndrome (AS) showed the highest efficacy rate, followed by those with Dravet syndrome (DS). 51 patients achieved at least 3 months of seizure freedom on the KD. Seizures recurred in 24 (47.1%) patients. None of the patients with AS relapsed, while those with DS had the highest recurrence rate. The etiology of epilepsy, KD maintenance treatment period, and electroencephalography (EEG) abnormalities during follow-up differed significantly between patients with and without recurrence. However, multivariate Cox regression analysis indicated that a KD maintenance treatment period of less than 12 months and the presence of EEG abnormalities during follow-up were significantly correlated with a higher risk of relapse. Epilepsy control was restored in 3 of the 24 (12.5%) patients who experienced relapse., Significance: KD appears to be effective in children with various types of drug-resistant epilepsy. A short KD maintenance treatment period and EEG abnormalities during follow-up were associated with an increased risk of seizure recurrence., (© 2023 International League Against Epilepsy.)

Background and Objectives: The impacts of nutritional status on clinical outcomes in children receiving umbilical cord blood stem cell transplantation (UCBT) are not fully described. We evaluated the risk for malnutrition before transplantation admission and influence of weight loss during hospitalization on short-term clinical outcomes in children with UCBT., Methods and Study Design: We conducted a retrospective study of pediatric patients up to age 18 years who received UCBT and were treated at the Children's Hospital of Fudan University between January 2019 and December 2020., Results: The mean age of the 91 patients was 1.3 years, with 78 (85.7%) men and 13 (14.3%) women (p<0.001). UCBT was performed mostly for primary immunodeficiency disease (PID) (83, 91.2%). The weight loss differences among children with different primary diseases were statistically significant (p=0.003). Children with a large amount of weight loss during hospitalization (n = 24) had higher risks of skin graft-versus-host disease (GVHD) (multivariate OR=5.01, 95% CI: 1.35-18.65), intestinal GVHD (multivariate OR=7.27, 95% CI: 1.74-30.45), a longer median hospital stay (p=0.004), higher antibiotic costs (p=0.008) and higher total hospitalization costs (p=0.004). Malnutrition on admission was significantly positively correlated with longer parenteral nutrition (PN) time (p=0.008). Early nutritional intervention effects on clinical outcomes need further assessment., Conclusions: Underweight recipient child and excessive weight loss during transplantation increases the length and cost of hospital stay, and is associated with a high incidence of GVHD, which affects the prognosis of transplantation and medical resources consumption.

A method based on elemental fingerprint, stable isotopic analysis and combined with chemometrics was proposed to trace the geographical origins of Licorice ( Glycyrrhiza uralensis Fisch) from 37 producing areas. For elemental fingerprint, the levels of 15 elements, including Ca, Cu, Mg, Pb, Zn, Sr, Mn, Se, Cd, Fe, Na, Al, Cr, Co, and K, were analyzed by inductively coupled plasma atomic emission spectrometry (ICP-AES). Three stable isotopes, including δ 13 C, δ 15 N, and δ 18 O, were measured using an isotope-ratio mass spectrometer (IRMS). For fine classification, three multiclass strategies, including the traditional one-versus-rest (OVR) and one-versus-one (OVO) strategies and a new ensemble strategy (ES), were combined with two binary classifiers, partial least squares discriminant analysis (PLSDA) and least squares support vector machines (LS-SVM). As a result, ES-PLSDA and ES-LS-SVM achieved 0.929 and 0.921 classification accuracy of GUF samples from the 37 origins. The results show that element fingerprint and stable isotope combined with chemometrics is an effective method for GUF traceability and provides a new idea for the geographical traceability of Chinese herbal medicine., Competing Interests: The authors declare that there are no conflicts of interest regarding the publication of this paper., (Copyright © 2022 Zhongying Lu et al.)

Objective: To evaluate the nutritional status of children with SMA types II and III in a Chinese population., Methods: We performed a retrospective medical record review of prospectively collected data from children with SMA types II and III in a single centre. We analysed data including clinical parameters, anthropometrics, and 24-hour dietary intake records in our clinic., Results: We analysed the anthropometric data from 86 children with 69 (80%) SMAII and 17 (20%) SMAIII; 47 (55%) were female, mean age was 5.22 ± 3.73 years. The WAZ of the SMAII ( n  = 69) and SMAIII ( n  = 17) were -0.48 (IQR -1.69, 0.57) vs -0.53 (IQR -1.60, 0.55), P  = 0.926; the HAZ were -0.62 (IQR -1.4, 0.3) vs -0.6 (IQR -1.61, 0.4), P =0.72; the BMIZ were -0.51 (IQR -1.53, 0.99) vs -0.08 (IQR -1.625, 1.125), P  = 0.537.The dietary intake of 51 children was compared to the Chinese Dietary Reference Intakes (DRIs). The actual energy intake in SMAII was similar to the DRIs, but which in SMAIII was less than the DRIs (1312.4 ± 329.5 kcal vs. 1655 ± 640.1 kcal, P  = 0.028). The protein intake in SMAII and SMAIII was higher than the DRIs (55 ± 16.3 g/d vs 30.2 ± 4.6 g/d, P  < 0.05; 56.8 ± 18.1 g/d vs 41.5 ± 17.5 g/d, p  = 0.22), and calcium intake was lower than the recommendation (507.7 ± 177.8 mg/d vs 731.7 ± 123.4 mg/d, P  < 0.05; 478.4 ± 207.4 mg/d vs 478.4 ± 207.4 mg/d, P  = 0.01). Swallowing on the Neuromuscular Disease Status Scale was 7.41 ± 0.5., Conclusions: Children with SMAII and SMAIII were at risk for malnutrition and low calcium intake.
