- Nutritional status at diagnosis among children with cancer referred to a nutritional service in Brazil(2021) VIANI, Karina; BARR, Ronald D.; FILHO, Vicente Odone; LADAS, Elena J.Introduction: Children and adolescents with cancer are particularly vulnerable to malnutrition and require special attention on nutritional assessment. An adequate nutritional status during treatment is essential in reducing morbidity and mortality, being a modifiable risk factor for clinical outcomes. This study aims to determine the nutritional status of pediatric patients with cancer assessed by the nutrition team at diagnosis and evaluate its association with the overall survival. Method: This is a retrospective cross-sectional study of patients at the time of cancer diagnosis who had nutritional assessments when hospitalized or referred to the nutrition outpatient clinic. Nutritional status was classified by the mid-upper arm circumference (MUAC) and body mass index for age z-score (zBMI/A). The Cox regression analysis was used to determine the association between the nutritional status and overall survival, adjusting for gender, tumor group and age. Results: The study included 366 patients. The prevalence of undernutrition varied from 8 to 23% and overweight, from 5 to 20%. The MUAC identified more children as undernourished than the zBMI/A in patients with solid and hematological tumors. There was no significant difference in the overall survival by malnutrition classified by the zBMI/A (p = 0.1507) or MUAC (p = 0.8135). When adjusted for gender, tumor group and age, the nutritional status classification by the zBMI/A (hazard ratio [HR], 1.27; 95% confidence interval [CI], 0.88-1.83; p = 0.209) and MUAC (HR, 0.94; 95% CI, 0.61-1.44; p = 0.773) did not impact overall survival. Conclusion: The nutritional status at diagnosis did not significantly impact the overall survival, which suggests there may have been a protective effect by successful nutritional intervention during the subsequent care.

Jane; LOCATELLI, Franco- A model for preservation of thymocyte-depleted thymus(2023) DIAS, A. S.; DAMACENO-RODRIGUES, N. R.; GIMENEZ, T. M.; OLIVEIRA, P. M.; ZERBINI, M. C.; CARNEIRO-SAMPAIO, M.; FILHO, V. Odone; JATENE, M. B.; VASCONCELOS, D. M.; ROCHA, V.; NOVAK, E. M.DiGeorge syndrome is a disorder caused by a microdeletion on the long arm of chromosome 22. Approximately 1% of patients diagnosed with DiGeorge syndrome may have an absence of a functional thymus, which characterizes the complete form of the syndrome. These patients require urgent treatment to reconstitute T cell immunity. Thymus transplantation is a promising investigational procedure for reconstitution of thymic function in infants with congenital athymia. Here, we demonstrate a possible optimization of the preparation of thymus slices for transplantation through prior depletion of thymocytes and leukocyte cell lineages followed by cryopreservation with cryoprotective media (5% dextran FP 40, 5% Me2SO, and 5% FBS) while preserving tissue architecture. Thymus fragments were stored in liquid nitrogen at -196 & DEG;C for 30 days or one year. The tissue architecture of the fragments was preserved, including the distinction between medullary thymic epithelial cells (TECs), cortical TECs, and Hassall bodies. Moreover, depleted thymus fragments cryopreserved for one year were recolonized by intrathymic injections of 3 x 106 thymocytes per mL, demonstrating the capability of these fragments to support T cell development. Thus, this technique opens up the possibility of freezing and storing large volumes of thymus tissue for immediate transplantation into patients with DiGeorge syndrome or atypical (Omenn-like) phenotype.
- High-Resolution Magic-Angle-Spinning NMR in Revealing Hepatoblastoma Hallmarks(2022) TASIC, Ljubica; AVRAMOVIC, Natasa; JADRANIN, Milka; QUINTERO, Melissa; STANISIC, Danijela; MARTINS, Lucas G. G.; COSTA, Tassia Brena Barroso Carneiro; NOVAK, Estela; ODONE, Vicente; RIVAS, Maria; AGUIAR, Talita; CARRARO, Dirce Maria; CUNHA, Isabela Werneck da; COSTA, Cecilia Maria Lima da; MASCHIETTO, Mariana; KREPISCHI, AnaCancer is one of the leading causes of death in children and adolescents worldwide; among the types of liver cancer, hepatoblastoma (HBL) is the most common in childhood. Although it affects only two to three individuals in a million, it is mostly asymptomatic at diagnosis, so by the time it is detected it has already advanced. There are specific recommendations regarding HBL treatment, and ongoing studies to stratify the risks of HBL, understand the pathology, and predict prognostics and survival rates. Although magnetic resonance imaging spectroscopy is frequently used in diagnostics of HBL, high-resolution magic-angle-spinning (HR-MAS) NMR spectroscopy of HBL tissues is scarce. Using this technique, we studied the alterations among tissue metabolites of ex vivo samples from (a) HBL and non-cancer liver tissues (NCL), (b) HBL and adjacent non-tumor samples, and (c) two regions of the same HBL samples, one more centralized and the other at the edge of the tumor. It was possible to identify metabolites in HBL, then metabolites from the HBL center and the border samples, and link them to altered metabolisms in tumor tissues, highlighting their potential as biochemical markers. Metabolites closely related to liver metabolisms such as some phospholipids, triacylglycerides, fatty acids, glucose, and amino acids showed differences between the tissues.

- Copy Number Alterations in Hepatoblastoma: Literature Review and a Brazilian Cohort Analysis Highlight New Biological Pathways(2021) BARROS, Juliana Sobral; AGUIAR, Talita Ferreira Marques; COSTA, Silvia Souza; RIVAS, Maria Prates; CYPRIANO, Monica; TOLEDO, Silvia Regina Caminada; NOVAK, Estela Maria; ODONE, Vicente; CRISTOFANI, Lilian Maria; CARRARO, Dirce Maria; CUNHA, Isabela Werneck da; COSTA, Cecilia Maria Lima; VIANNA-MORGANTE, Angela M.; ROSENBERG, Carla; KREPISCHI, Ana Cristina VictorinoHepatoblastoma (HB) is a rare embryonal tumor, although it is the most common pediatric liver cancer. The aim of this study was to provide an accurate cytogenomic profile of this type of cancer, for which information in cancer databases is lacking. We performed an extensive literature review of cytogenetic studies on HBs disclosing that the most frequent copy number alterations (CNAs) are gains of 1q, 2/2q, 8/8q, and 20; and losses at 1p and 4q. Furthermore, the CNA profile of a Brazilian cohort of 26 HBs was obtained by array-CGH; the most recurrent CNAs were the same as shown in the literature review. Importantly, HBs from female patients, high-risk stratification tumors, tumors who developed in older patients (> 3 years at diagnosis) or from patients with metastasis and/or deceased carried a higher diversity of chromosomal alterations, specifically chromosomal losses at 1p, 4, 11q and 18q. In addition, we distinguished three major CNA profiles: no detectable CNA, few CNAs and tumors with complex genomes. Tumors with simpler genomes exhibited a significant association with the epithelial fetal subtype of HBs; in contrast, the complex genome group included three cases with epithelial embryonal histology, as well as the only HB with HCC features. A significant association of complex HB genomes was observed with older patients who developed high-risk tumors, metastasis, and deceased. Moreover, two patients with HBs exhibiting complex genomes were born with congenital anomalies. Together, these findings suggest that a high load of CNAs, mainly chromosomal losses, particularly losses at 1p and 18, increases the tendency to HB aggressiveness. Additionally, we identified six hot-spot chromosome regions most frequently affected in the entire group: 1q31.3q42.3, 2q23.3q37.3, and 20p13p11.1 gains, besides a 5,3 Mb amplification at 2q24.2q24.3, and losses at 1p36.33p35.1, 4p14 and 4q21.22q25. An in-silico analysis using the genes mapped to these six regions revealed several enriched biological pathways such as ERK Signaling, MicroRNAs in Cancer, and the PI3K-Akt Signaling, in addition to the WNT Signaling pathway; further investigation is required to evaluate if disturbances of these pathways can contribute to HB tumorigenesis. The analyzed gene set was found to be associated with neoplasms, abnormalities of metabolism/homeostasis and liver morphology, as well as abnormal embryonic development and cytokine secretion. In conclusion, we have provided a comprehensive characterization of the spectrum of chromosomal alterations reported in HBs and identified specific genomic regions recurrently altered in a Brazilian HB group, pointing to new biological pathways, and relevant clinical associations.
- A longitudinal study of the peripheral and central auditory pathways in individuals with acute lymphoid leukemia(2023) VOSGRAU, Jessica Sales; SILVA, Liliane Aparecida Fagundes; FILHO, Vicente Odone; MATAS, Carla GentileObjective: To characterize the peripheral and central auditory pathways in individuals with Acute Lymphoid Leukemia (ALL) and compare assessment results before and during chemotherapy. Method: The study included 17 subjects with ALL, divided into two age groups: 3 to 6 (11 individuals) and 7 to 16 years old (6 individuals). Each subject was evaluated twice (before and 3 to 6 months after chemotherapy treatment) with the following procedures: medical history survey, otoscopy, Pure-Tone Threshold (PTA) and speech audiometry, acoustic immittance measures, Brainstem Auditory Evoked Potentials (BAEP) and LongLatency Auditory Evoked Potentials (LLAEP).Results: PTA was normal. Tympanometry was abnormal in the second assessment in 2 individuals aged 3 to 6 years. One subject in each age group had absent ipsilateral acoustic reflexes. In high-frequency audiometry, 1 individual had abnormal results. BAEP was abnormal in 5 (first assessment) and 7 individuals (second assessment) aged 3 to 6 years and 2 (first assessment) and 1 individual (second assessment) aged 7 to 16 years. As for LLAEP, P1 latency was increased in 5 (first assessment) and 7 individuals (second assessment) aged 3 to 6 years.Conclusion: No hearing loss was identified in the behavioral audiological assessment. BAEP was more affected in the 3-to-6-year-old group, with greater impairment in the lower brainstem in the first and second assessments. In LLAEP, P1 was the most impaired component in children aged 3 to 6 years, and P2 and N2 were so for those 7 to 16 years old, especially in the second assessment.
- Perceptions of Health Professionals on the Implementation of Integrative and Complementary Practices at a University Pediatric Hospital in Brazil: A Qualitative Interview Study(2023) TROENDLE, Marc; SOUZA, Danton Matheus de; POLASTRINI, Rita Tiziana Verardo; ODONE FILHO, Vicente; SEIFERT, Georg; STRITTER, Wiebke; BLAKESLEE, Sarah B.; MUCCI, Ana Lucia dos Santos Teco; PASQUALUCCI, Paula LageBackground: Despite an increase in use of pediatric complementary and integrative health (PCIH), many healthcare professionals still have an inadequate understanding of such practices and consider their use inappropriate, which might thwart implementation processes. In a qualitative interview study we examined the feedback of conventional healthcare professionals about the integrative practices provided to pediatric patients by an integrative team in a pediatric oncological hospital.Methods: Fifteen semi-structured interviews were carried out with various conventional healthcare professionals in an university pediatric hospital in Sao Paulo, Brazil. The interviews were audio-recorded, transcribed and pseudonymized. DSCsoft (R) and MAXQDA (R) software assisted in a profound qualitative analysis using the collective subject discourse and thematic analysis method in order to display participants' perspectives on PCIH and the project in their hospital.Results: Interviewees acknowledged their lack of knowledge about PCIH practices and reflected on the limits of their care as well as on new possibilities PCIH could offer. PCIH was perceived by interviewees as an effective supportive tool of care to promote patients' wellbeing, assist overall compliance, strengthen cooperation between professionals, children and their relatives and hence facilitated general patient care. Since PCIH was implemented in their clinic, perceptions led interviewees to wish for increased PCIH offering and a more profound integration of its therapists into the standard of care.Discussion: The coexistence of integrative and conventional practices in the conventional healthcare setting is important to give visibility to the possibilities offered by the integrative pediatrics field. Regular and constant encounters with integrative practices, as well as information access seem crucial to reach a wider openness for PCIH and subsequently a broader application and dissemination of it.
