Surgery in Bilateral Wilms Tumor-A Single-Center Experience.

The treatment of bilateral Wilms tumors (BWT) involves curing the cancer, preserving long-term renal function, and maintaining a good quality of life. Established methods for achieving these goals include preoperative chemotherapy and nephron-sparing surgery (NSS). This study aimed to evaluate the experience of a single institution in treating patients with BWT. We analyzed cases of BWT treated at the Pediatric Oncology Institute-GRAACC-Federal University of São Paulo over a period of 35 years. Bleeding control was performed with manual compression of the renal parenchyma. Thirty-three patients were included in the study. Thirty cases were synchronous tumors. The mean age at diagnosis was 30.4 months (±22 m) and 66.7% were girls. The median follow-up period was 83 months. Neoadjuvant chemotherapy was the primary approach in most patients (87.9%), with a simultaneous upfront surgical approach performed in 84.8%. Most patients underwent bilateral NSS (70.4%). There were no early complications in this series, but 39.4% had clinical complications. The five-year survival rate was 76%. Therefore, it is clear that the surgical approach to BWT plays a crucial role in achieving good outcomes. However, it is difficult to standardize surgical techniques and technology may have the potential to enhance safety.

Survival analysis and prognostic factors in posterior fossa ependymomas in children and adolescents.

OBJECTIVE: In this study, the authors aimed to analyze the overall survival (OS) and progression-free survival (PFS) of patients younger than 18 years of age who were diagnosed with posterior fossa ependymomas, and to identify prognostic factors such as the degree of resection, tumor topography, and involvement of the lesion in the hindbrain. METHODS: The authors performed a retrospective cohort study of patients younger than 18 years of age, treated beginning in 2000, with a diagnosis of posterior fossa ependymoma. Ependymomas were separated into three groups: tumors restricted to the fourth ventricle, tumors inside the fourth ventricle and exiting from the foramen of Luschka, and tumors inside the fourth ventricle and completely surrounding the hindbrain. Furthermore, the tumors were classified by molecular group using the staining method for H3K27me3. Statistical analysis was performed using Kaplan-Meier survival curves, with p < 0.05 considered statistically significant. RESULTS: Of 1693 patients who underwent surgical treatment between January 2000 and May 2021, 55 patients who met the inclusion criteria were included. The median age at diagnosis was 2.98 years. The median OS was 44 months, and the survival rates at 1, 5, and 10 years were 92.5%, 49.1%, and 38.3%, respectively. The cases were assigned to two posterior fossa ependymoma molecular groups: 35 (63.6%) cases to group A and 8 (14.5%) to group B. The median ages in groups A and B were 2.94 and 2.85 years and the median OS values were 44 and 38 months, respectively (p = 0.9245). Statistical analysis was performed on multiple variables, including age, sex, histological grade, Ki-67 expression, tumor volume, extent of resection, and adjuvant therapies. The median PFS of patients with dorsal-only involvement was 28 months; for dorsolateral involvement, it was 15 months; and for total involvement, it was 9.5 months (p = 0.0464). No statistically significant difference was found for OS. There was a statistically significant difference between the proportion of patients in whom gross-total resection was achieved in the dorsal-only involvement group (73.1%, 19/26) and those in the total involvement group (0%, 0/6) (p = 0.0019). CONCLUSIONS: This study confirmed that the extent of resection has an impact on OS and PFS. The authors found that adjuvant radiotherapy resulted in a higher OS but did not prevent progression, that the pattern of involvement of the brainstem in the tumor at diagnosis could elicit important information regarding the patient's prognosis regarding PFS, and that the total involvement of the rhombencephalon impaired the gross-total resection of these tumors.

Sintomas depressivos, ansiedade e os sintomas estressantes durante a gravidez afetam o ganho de peso gestacional? / Do depressive symptoms, anxiety and stressful symptoms during pregnancy affect gestational weight gain?

Resumo O objetivo deste artigo é estimar os efeitos dos sintomas de transtornos mentais na gravidez (sintomas depressivos, ansiedade e estresse) no ganho de peso gestacional. Estudo longitudinal, realizado com dados da Coorte de nascimento BRISA, iniciada em 2010 em São Luís, Maranhão. O ganho de peso gestacional foi classificado de acordo com Institute of Medicine. A variável independente foi um construto (variável latente) nomeado de sintomas de transtornos mentais, englobando as variáveis sintomas depressivos, a ansiedade e os sintomas estressantes (todas de forma contínua). Utilizou-se modelagem de equações estruturais, a fim de investigar a associação entre a saúde mental e ganho de peso. Em relação a associação entre sintomas de transtornos mentais e ganho de peso na gestação, não se encontrou efeito total (CP=0,043; p=0,377). Em relação aos efeitos indiretos, também não se encontrou efeito através dos comportamentos de risco (CP=0,03; p=0,368) e através da atividade física (CP=0,00; p=0,974). Finalmente os dados não evidenciaram efeito direto dos sintomas de transtornos mentais durante a gravidez como o ganho de peso gestacional (CP=0,050; p=0,404). O ganho de peso gestacional não apresentou efeito direto, indireto e total nos sintomas de transtornos mentais de gestantes.

Abstract The scope of this article is to estimate the effects of symptoms of mental disorders during pregnancy (depressive symptoms, anxiety and stress) on gestational weight gain (kg). It is a longitudinal study, carried out with data from the BRISA Birth Cohort, which was launched in 2010 in São Luís, Maranhão. Gestational weight gain was classified according to the Institute of Medicine. The independent variable was a construct (latent variable) referred to as symptoms of mental disorders, made up of the depressive symptoms, anxiety and stressful symptoms variables (all on an ongoing basis). Structural equation modeling was used to investigate the association between mental health and weight gain. Regarding the association between symptoms of mental disorders and weight gain during pregnancy, no total effect was found (PC=0.043; p=0.377). Regarding indirect effects, no effect was found either through risk behaviors (PC=0.03; p=0.368) or through physical activity (PC=0.00; p=0.974). Finally, the data did not show a direct effect of symptoms of mental disorders during pregnancy such as gestational weight gain (PC=0.050; p=0.404). Gestational weight gain had no direct, indirect or total effect on symptoms of mental disorders in pregnant women.

Pharmacogenetics of the Primary and Metastatic Osteosarcoma: Gene Expression Profile Associated with Outcome.

Osteosarcoma (OS) is the most common malignant bone tumor in children and adolescents. In recent decades, OS treatment has reached a plateau and drug resistance is still a major challenge. Therefore, the present study aimed to analyze the expression of the genes related to pharmacogenetics in OS. The expression of 32 target genes in 80 paired specimens (pre-chemotherapeutic primary tumor, post-chemotherapeutic primary tumor and pulmonary metastasis) obtained from 33 patients diagnosed with OS were analyzed by the real-time PCR methodology. As the calibrators (control), five normal bone specimens were used. The present study identified associations between the OS outcome and the expression of the genes TOP2A, DHFR, MTHFR, BCL2L1, CASP3, FASLG, GSTM3, SOD1, ABCC1, ABCC2, ABCC3, ABCC5, ABCC6, ABCC10, ABCC11, ABCG2, RALBP1, SLC19A1, SLC22A1, ERCC1 and MSH2. In addition, the expression of the ABCC10, GGH, GSTM3 and SLC22A1 genes were associated with the disease event, and the metastasis specimens showed a high expression profile of ABCC1, ABCC3 and ABCC4 genes and a low expression of SLC22A1 and ABCC10 genes, which is possibly an important factor for resistance in OS metastasis. Therefore, our findings may, in the future, contribute to clinical management as prognostic factors as well as possible therapeutic targets.

Quantitative expression evaluation of PRAME gene in osteosarcoma.

BACKGROUND: In a previous study, our group observed that 68% of the osteosarcoma (OS) samples presented PRAME (Preferentially Expressed Antigen in Melanoma) gene expression. In this work, we propose to investigate quantitatively gene expression of PRAME in distinct patients groups. METHODS AND RESULTS: 61 osteosarcoma samples, from 3 distinct patients groups were selected for this study: (1) Patients younger than 10 years old at diagnosis, (2) Patients that had poor evolution of disease and (3) Patients that were in remission of disease and had treatment with no intercurrences) PRAME gene expression levels were obtained using quantitative Real-Time Polymerase Chain Reaction method (qRT-PCR). Clinical parameters were collected from patient's medical charts. Results demonstrated an increase in PRAME gene expression in all samples, with high variation in expression levels, when considering all samples and when analyzed in each group. In addition, no statistical difference was found when considering clinical data collected or patients groups. CONCLUSION: PRAME gene expression quantitative investigation did not bring any complementary information beyond of what had already been observed in other qualitative investigations published by our group, there is no relation between PRAME gene expression levels and disease evolution. However, the findings in this work contribute for validation PRAME gene expression as a good biomarker to OS, which, in the future, may allow identification circulating tumor cell or molecules to contribute with early diagnostic of metastasis, a genuine problem in OS that determinate flattening in survival curves.

Para além do imaginável: experiências vividas por profissionais de saúde em UTI durante a pandemia da Covid-19 / Beyond the imaginable: experiences lived by ICU health professionals during the Covid-19 pandemic

Resumo Objetivou-se analisar experiências de profissionais relacionadas às mudanças no trabalho em saúde em Unidade de Terapia Intensiva, durante o período crítico da primeira onda da pandemia da Covid-19 no Maranhão. Estudo descritivo-exploratório, de abordagem qualitativa, desenvolvido nas Unidades de Terapia Intensiva de hospitais públicos no Maranhão, de novembro de 2020 a janeiro de 2021. Participaram do estudo 15 profissionais. A técnica utilizada para coleta de dados foi a entrevista semiestruturada, com amostra definida pelo critério de saturação dos sentidos. Utilizaram-se da análise de conteúdo e do software NVIVO® 12. Evidenciou-se que sobrecarga de trabalho, escassez de profissionais e o medo do contágio afetaram a qualidade da assistência e geraram novas formas de produção do cuidado. Naquele contexto, ofertar a assistência de "alto padrão" foi um desafio que perpassou os espaços social e técnico da terapia intensiva. Vivenciar as mortes em maior escala afetou as relações intersubjetivas nas esferas pessoal e profissional. As mudanças na organização do espaço, a assistência e as relações interprofissionais podem indicar caminhos para se repensar os efeitos desse fenômeno para agentes, usuários e serviços, além de fornecer maiores habilidades para lidar com cenários emergenciais futuros.

Abstract The study aimed to analyze the experiences lived by professionals related to changes in health work in the Intensive Care Unit, during the critical period of the first wave of the Covid-19 pandemic in Maranhão. This is a descriptive-exploratory study with a qualitative approach, carried out in the Intensive Care Units of public hospitals in Maranhão, from November 2020 to January 2021. Fifteen professionals took part in the study. Data collection was done through semi-structured interviews, with the sample defined by the criterion of saturation of meanings. Content analysis and NVIVO® 12 software were used. It emerged that work overload, shortage of professionals and fear of contagion affected the quality of care and generated new ways of producing care. In that context, providing "high standard" care was a challenge cutting across the social and technical spaces of intensive care. Experiencing deaths on a larger scale affected intersubjective relationships in personal and professional spheres. Changes in the organization of space, care and interprofessional relationships may indicate ways to rethink the effects of this phenomenon on agents, users and services, as well as providing greater skills to deal with future emergency scenarios.

Processo de trabalho em Clínicas Populares de Saúde na perspectiva de médicos / El proceso de trabajo en Clínicas Populares de Salud bajo la perspectiva de médicos / Work process in Low-Cost Health Clinics from the perspective of physicians

O objetivo deste estudo foi compreender a perspectiva de médicos acerca do processo de trabalho em Clínicas Populares de Saúde. Para isso, realizamos uma pesquisa qualitativa na qual foram entrevistados oito jovens médicos especialistas que atuam nessas empresas em São Luís, Maranhão. Identificamos condições precarizadas de trabalho, mas com pouca resistência por parte dos médicos, considerando que essas empresas são encaradas como espaços de projeção no mercado de trabalho local. Devido às limitações do modelo assistencial do tipo queixa-conduta, os entrevistados acionam uma rede informal e os usuários das Clínicas Populares de Saúde são encaminhados para o Sistema Único de Saúde (SUS). Assim, o processo de trabalho do médico é desafiado por esse modelo assistencial fragmentado, o que faz borrar os limites nas interfaces público-privado na medida em que uma dupla porta de entrada para o SUS é naturalizada.(AU)

El objetivo de este estudio fue comprender la perspectiva de médicos sobre el proceso de trabajo en Clínicas Populares de Salud.

Identificamos condiciones precarias de trabajo, pero con poca resistencia por parte de los médicos, considerando que esas empresas son consideradas como espacios de proyección en el mercado de trabajo local. Debido a las limitaciones del modelo asistencial del tipo queja-conducta, los entrevistados ponen en acción una red informal y los usuarios de las Clínicas Populares de Salud son derivados para el Sistema Brasileño de Salud (SUS). De tal forma, el proceso de trabajo del médico es desafiado por ese modelo asistencial fragmentado, lo que borra los límites de las interfaces público-privado a medida que se naturaliza una doble puerta de entrada al SUS.(AU)

The objective of the study was to understand the perspective of doctors regarding the work process in Low-cost Health Clinics. To this end, we conducted qualitative research interviewing 8 young specialist doctors who work in these business firms in São Luís, Maranhão. We identified precarious working conditions, although presenting little resistance from the doctors, considering that these businesses are seen as spaces of projection in the local job market. Due to the limitations of the complaint-driven model of care, the interviewees activate an informal network, and the users of the Low-Cost Health Clinics are referred to the Brazilian National Health System (SUS). Thus, the physician's work process is challenged by this fragmented care model, which blurs the boundaries in the public-private interfaces leading to a naturalized double gateway to the SUS.(AU)

Challenges in the care of children born to mothers diagnosed with COVID-19 during the pandemic / Desafíos en la atención de niños nacidos de madres diagnosticadas con COVID-19 durante la pandemia / Desafios no cuidado de crianças nascidas de mães com diagnóstico de COVID-19 durante a pandemia

ABSTRACT Objective: To understand the challenges in the care of children born to mothers with COVID-19 during the pandemic. Method: Qualitative research, conducted from November 2020 to May 2021, in two public maternity hospitals, with women who had children during the first wave of the pandemic, diagnosed with COVID-19 during pregnancy and/or childbirth. There were nineteen semi-structured interviews with thematic analysis. Symbolic Interactionism was used as a theoretical framework. Results: Changes in the care for newborn children were identified. In the domestic environment, hygiene measures with the newborn children were intensified, social isolation restricted the support network and mothers felt alone and overwhelmed. In terms of health care, there was a setback in neonatal care and interruption of professional care, such as the suspension of appointments. Conclusion: The pandemic has restructured traditional models of family care, intensified difficulties in accessing healthcare, and exposed children to inherent risks due to a lack of proper follow-up.

RESUMEN Objetivo: Comprender los desafíos en el cuidado de niños nacidos de madres con COVID-19 durante una pandemia.

Prevalence of self-medication and associated factors in adolescents aged 18-19 years: the 1997/1998 cohort in São Luís-MA, Brazil / Prevalência de automedicação e fatores associados em adolescentes de 18-19 anos: a coorte de 1997/1998 em São Luís-MA, Brasil

Abstract This article aims to assess the prevalence and factors associated with self-medication in adolescents. Cross-sectional study, nested in cohort, with 2,515 adolescents aged 18-19 years born in São Luís-MA. The use of medication in the last 15 days without a medical prescription or by a qualified professional was considered self-medication. Factors associated with self-medication were evaluated using Poisson regression with robust variances and hierarchical selection of variables. Medicines were used in the last 15 days by 48.05% of adolescents. Among these, 70.09% use it without a prescription or indication from another health professional. The most used medications for self-medication were "over the counter" (93.68%). Self-medication was positively associated with female gender (PR: 1.41; 95%CI: 1.25-1.59), screen time ≥5h/day (PR: 1.32; 95%CI: 1.05-1.67) and self-reported diagnosis of allergic rhinitis (PR: 1.19; 95%CI: 1.02-1.39); however, negatively associated with self-satisfaction with health (PR: 0.79; 95%CI: 0.67-0.94) and hospitalization in the previous year (PR: 0.70; 95%CI: 0.50-0.97). Self-medication was common among adolescents and to reduce this practice, greater attention should be given to women, individuals with intense exposure to meshes and allergic diseases.

Resumo O objetivo deste artigo é avaliar a prevalência e os fatores associados a automedicação em adolescentes. Estudo transversal, aninhado a uma coorte, com 2.515 adolescentes de 18-19 anos nascidos em São Luís-MA. O uso de algum medicamento nos últimos 15 dias sem prescrição médica ou de profissional habilitado foi considerado automedicação. Os fatores associados a automedicação foram avaliados usando regressão de Poisson com variâncias robustas e seleção hierárquica das variáveis. Medicamentos foram utilizados nos últimos 15 dias por 48,05% dos adolescentes. Entre estes, 70,09% fazem uso sem receita médica ou indicação de outro profissional de saúde. Os medicamentos mais utilizados na automedicação foram os "over the counter" (93,68%). A automedicação foi positivamente associada ao sexo feminino (RP: 1,41; IC95%: 1,25-1,59), tempo de tela ≥5h/dia (RP: 1,32; IC95%: 1,05-1,67) e diagnóstico autorreferido de rinite alérgica (RP: 1,19; IC95%: 1,02-1,39); porém, negativamente associada a autossatisfação com a saúde (PR: 0,79; IC95%: 0,67-0,94) e hospitalização no ano anterior (RP: 0,70; IC95%: 0,50-0,97). A automedicação foi comum entre os adolescentes e para redução dessa prática uma maior atenção deve ser dada a mulheres, indivíduos com intensa exposição a telas e doenças alérgicas.

Is sleep time associated with handgrip strength in adolescents from the 1997/1998 São Luís Birth Cohort? / O tempo de sono está associado à força de preensão manual em adolescentes da Coorte de São Luís de 1997/1998?

Abstract This article aims to analyze the association between sleep time and handgrip strength in adolescents belonging to the 1997/1998 São Luís Birth Cohort. This was a cross-sectional study nested in a birth cohort study. One thousand two hundred sixty-nine individuals (18 and 19 years) wore an Actigraph® GTX3+ accelerometer on their wrist 24 hr/day for 7 consecutive days. Handgrip strength was measured using a digital hand dynamometer. We used directed acyclic graphs (DAG) to identify confounding variables. This sample of adolescents was mostly composed of men, with brown skin color, economic class C, which did not work, did not consume alcohol, did not smoke, and never used drugs. The mean value of handgrip strength was 28.2 (±9.3) kgf, and the mean of sleep time was 6 (±1.0) hours per day. The crude analysis showed an association between sleep time and muscle strength. An increase of one hour of sleep reduced the handgrip strength by 1.95 kgf (95%CI:-2.51;-1.39). However, after adjustment for confounders, the association was not maintained (β:-0.07; 95%CI:-0.48;0.36). Sleep time is not associated with handgrip strength in adolescents in São Luís.

Resumo O objetivo deste artigo é analisar a associação entre tempo de sono e força de preensão manual em adolescentes da Coorte de Nascimentos de São Luís 1997/1998. Estudo transversal aninhado a um estudo de coorte de nascimentos. Mil duzentos e sessenta e nove indivíduos (18 e 19 anos) usaram um acelerômetro Actigraph® GTX3 + em seu pulso 24 horas/dia por sete dias consecutivos. A força de preensão manual foi medida por meio de um dinamômetro digital de mão. Usou-se gráficos acíclicos direcionados (DAG) para identificar variáveis ​​de confusão. A amostra de adolescentes foi composta em sua maioria por homens, de cor da pele parda, classe econômica C, que não trabalhava, não consumiam álcool, não fumavam e nunca usaram drogas. O valor médio da força de preensão manual foi de 28,2 (±9,3) kgf, e a média do tempo de sono foi de seis (±1,0) horas por dia. A análise bruta mostrou associação entre tempo de sono e força muscular. O aumento de uma hora de sono reduziu a força de preensão manual em 1,95 kgf (IC95%:-2,51;-1,39). No entanto, após o ajuste para fatores de confusão, a associação não foi mantida (β:-0,07; IC95%:-0,48;0,36). O tempo de sono não foi associado à força de preensão manual em adolescentes de São Luís.

Gliomas in children and adolescents: investigation of molecular alterations with a potential prognostic and therapeutic impact.

PURPOSE: Gliomas represent the most frequent central nervous system (CNS) tumors in children and adolescents. However, therapeutic strategies for these patients, based on tumor molecular profile, are still limited compared to the wide range of treatment options for the adult population. We investigated molecular alterations, with a potential prognostic marker and therapeutic target in gliomas of childhood and adolescence using the next-generation sequencing (NGS) strategy. METHODS: We selected 95 samples with initial diagnosis of glioma from patients treated at Pediatric Oncology Institute-GRAACC/UNIFESP. All samples were categorized according to the 2021 World Health Organization Classification of Tumors of the CNS, which included 39 low-grade gliomas (LGGs) and 56 high-grade gliomas (HGGs). Four HGG samples were classified as congenital glioblastoma (cGBM). NGS was performed to identify somatic genetic variants in tumor samples using the Oncomine Childhood Cancer Research Assay® (OCCRA®) panel, from Thermo Fisher Scientific®. RESULTS: Genetic variants were identified in 76 of 95 (80%) tumors. In HGGs, the most common molecular alteration detected was H3F3A c.83A > T variant (H3.3 K27M) and co-occurring mutations in ATRX, TP53, PDGFRA, MET, and MYC genes were also frequently observed. One HGG sample was reclassified as supratentorial ependymoma ZFTA-fusion positive after NGS was performed. In LGGs, four KIAA1549-BRAF fusion transcripts were detected and this alteration was the most recurrent genetic event and favorable prognostic factor identified. Additionally, genetic variants in ALK and NTRK genes, which provide potential targets for therapy with Food and Drug Administration-approved drugs, were identified in two different cases of cGBM that were classified as infant-type hemispheric glioma, a newly recognized subgroup of pediatric HGG. CONCLUSION: Molecular profiling by the OCCRA® panel comprehensively addressed the most relevant genetic variants in gliomas of childhood and adolescence, as these tumors have specific patterns of molecular alterations, outcomes, and effectiveness to therapies.

Decline in head circumference growth and associated factors in congenital Zika syndrome / Declínio no crescimento do perímetro cefálico e fatores associados à síndrome congênita associada à infecção pelo vírus Zika / Disminución del crecimiento del perímetro cefálico y factores asociados en el síndrome congénito del Zika

Little is known about the evolution of head circumference (HC) in children with congenital Zika syndrome (CZS). This study aims to evaluate HC growth in children with CZS in the first three years of life and identify associated factors. HC data obtained at birth and in neuropediatric consultations from 74 children with CZS were collected from the Child's Health Handbook, parents' reports, and medical records. Predictors of HC z-score were investigated using different mixed-effects models; Akaike's information criterion was used for model selection. The HC z-score decreased from -2.7 ± 1.6 at birth to -5.5 ± 2.2 at 3 months of age, remaining relatively stable thereafter. In the selected adjusted model, the presence of severe brain parenchymal atrophy and maternal symptoms of infection in the first trimester of pregnancy were associated with a more pronounced reduction in the HC z-score in the first three years of life. The decrease of HC z-score in CZS children over the first three months demonstrated a reduced potential for growth and development of the central nervous system of these children. The prognosis of head growth in the first 3 years of life is worse when maternal infection occurs in the first gestational trimester and in children who have severe brain parenchymal atrophy.

Pouco se sabe sobre a evolução do perímetro cefálico (PC) em crianças com síndrome congênita associada à infecção pelo vírus Zika (SCZ) em acompanhamentos contínuos. Este estudo buscou avaliar o crescimento do PC em crianças com SCZ nos primeiros três anos de suas vidas e identificar os fatores associados a ele. Os dados do PC ao nascimento e obtidos em consultas neuropediátricas de 74 crianças com SCZ foram coletados no Cartão da Criança, nos laudos paternos e em seus prontuários. Os preditores de escore-z para PC foram investigados utilizando-se diferentes modelos de efeitos mistos. O critério de informação de Akaike foi utilizado para selecionar os modelos usados. O escore-z de PC diminuiu de -2,7 ± 1,6 ao nascimento para -5,5 ± 2,2 aos 3 meses de idade, mas permaneceu relativamente estável desde então. No modelo ajustado selecionado, a presença de atrofia parênquimal cerebral grave e sintomas maternos de infecção no primeiro trimestre de sua gravidez estiveram associados a uma redução mais acentuada no escore-z de PC nos primeiros três anos de vida dos participantes. A diminuição do escore-z de PC em crianças com SCZ nos primeiros 3 meses de sua vida monstra o potencial reduzido de crescimento e desenvolvimento do sistema nervoso central dessas crianças. O prognóstico de crescimento do perímetro cefálico nos primeiros 3 anos de vida é pior quando a infecção materna ocorreu no primeiro trimestre gestacional e em crianças que tiveram atrofia parênquimal grave.

Se conoce poco sobre la evolución del perímetro cefálico (PC) en niños con síndrome de Zika congénito (SZC) en los seguimientos continuos. El objetivo del estudio fue evaluar el crecimiento del PC en niños con SZC en los primeros 3 años de vida e identificar los factores asociados. Se recogieron datos del PC al nacimiento y obtenidos en las consultas de neuropediatría de 74 niños con SZC a partir de la Tarjeta del Niño, los informes de los padres y los registros médicos. Se investigaron los predictores de la puntuación Z del PC mediante diferentes modelos de efectos mixtos; se utilizó el criterio de información de Akaike para la selección del modelo. La puntuación Z del PC disminuyó de -2,7 ± 1,6 al nacer a -5,5 ± 2,2 a los 3 meses de edad, pero a partir de entonces se mantuvo relativamente estable. En el modelo ajustado seleccionado, la presencia de atrofia grave del parénquima cerebral y los síntomas maternos de infección en el primer trimestre del embarazo se asociaron con una reducción más pronunciada de la puntuación Z del PC en los primeros 3 años de vida. La disminución de la puntuación Z del PC en los niños con SZC durante los primeros 3 meses demuestra el menor potencial de crecimiento y desarrollo del sistema nervioso central de estos niños. El pronóstico del crecimiento de la cabeza en los primeros 3 años de vida es peor cuando la infección materna se produjo en el primer trimestre gestacional y en los niños que tenían una atrofia grave del parénquima cerebral.

Physical activity in birth cohorts of three Brazilian cities (Ribeirão Preto, Pelotas, and São Luís): A cross-sectional study / Atividade física em coortes de nascimento de três cidades brasileiras (Ribeirão Preto, Pelotas e São Luís): estudo transversal

ABSTRACT Objective: To describe the prevalence of physical activity among subjects from birth cohorts of three cities located in different regions of Brazil according to sociodemographic characteristics and sex, comparing the relationships within and between cohorts. Methods: Cross-sectional study involving 12,724 adolescents and young adults who participated in five birth cohorts: Ribeirão Preto [1978/79 (37/39 years old in 2016) and 1994 (22 years in 2016)]; Pelotas [1982 (30 years in 2012) and 1993 (22 years in 2015)], and São Luís [1997/98 (18/19 years in 2016)]. Leisure-time physical activity was evaluated with questionnaires (insufficiently active: <150 min/week and active: ≥150 min/week) and moderate and vigorous physical activity (MVPA) was objectively measured by accelerometry. Those, in each city, were evaluated accordingly to skin color, socioeconomic classification, and study/work activities. Results: The prevalence of leisure-time physical activity ranged from 29.2% at 30 years old in Pelotas to 54.6% among adolescents from São Luís. The prevalence of leisure-time physical activity was higher among younger people (54.6% in São Luís 1997), while the same was not observed for total physical activity. MVPA (3rd tercile) was higher in the cohorts from Pelotas and São Luís. The prevalence of leisure-time physical activity and MVPA was higher in men. The data showed that the variation in physical activity was associated with sex and sociodemographic conditions in all cohorts. Conclusion: Sociodemographic characteristics should be considered when promoting leisure-time physical activity and actions aimed at young people, and adults who are more socioeconomically vulnerable should be encouraged.

RESUMO Objetivo: Descrever a prevalência de atividade física entre sujeitos de coortes de nascimento de três cidades localizadas em diferentes regiões do Brasil segundo características sociodemográficas e sexo, comparando relações intra e intercoortes. Métodos: Estudo transversal com 12.724 adolescentes e adultos jovens que participaram de cinco coortes de nascimento: Ribeirão Preto [1978/79 (37/39 anos em 2016) e 1994 (22 anos em 2016)]; Pelotas [1982 (30 anos em 2012) e 1993 (22 anos em 2015)] e São Luís [1997/98 (18/19 anos em 2016)]. A atividade física no lazer foi avaliada com questionários (insuficientemente ativo: <150 min/semana; ativo: ≥150 min/semana) e a atividade física moderada e vigorosa (AFMV) foi medida objetivamente por acelerometria. Foram avaliadas a cor da pele, a classificação socioeconômica e as atividades de estudo/trabalho. Resultados: A prevalência de ativos no lazer variou de 29,2% aos 30 anos em Pelotas a 54,6% entre os adolescentes de São Luís. A prevalência de ativos no lazer foi maior entre os mais jovens (54,6% em São Luís/1997), o que não foi observado para a atividade física total. A AFMV (3o tercil) foi maior nas coortes de Pelotas e São Luís. A prevalência de ativos no lazer e a AFMV foi maior nos homens. Os dados mostraram que a variação da atividade física foi associada ao sexo e às condições sociodemográficas em todas as coortes. Conclusão: As características sociodemográficas devem ser consideradas na promoção da atividade física no lazer e as ações voltadas para jovens e adultos mais vulneráveis socioeconomicamente devem ser incentivadas.

From prenatal to postpartum care: changes in obstetric health services during the covid-19 pandemic / Del prenatal ao posparto: cambios en los serviços de saúde obstétricos durante la pandemia de la covid-19 / Do pré-natal ao puerpério: mudanças nos serviços de saúde obstétricos durante a pandemia da covid-19

ABSTRACT Objective: to analyze changes in maternal health care during the Covid-19 pandemic, according to reports by health professionals. Method: qualitative research, conducted with managers, physicians, nurses, residents and nursing technicians working in a prenatal outpatient clinic, obstetric emergency department, delivery center and obstetric inpatient ward of a high complexity federal public hospital in the Northeast of Brazil. Data were collected from December 2020 to August 2021. The sample, chosen intentionally, sought the diversity of characteristics and situations, was closed by the criterion of saturation of meaning. A structured questionnaire and a semi-structured interview script were used for data collection. The interviews were recorded and transcribed. Content analysis was used in the thematic modality. Results: 28 professionals were interviewed. Changes in the dynamics of obstetric care were identified and categorized as: prenatal care; and childbirth/postpartum. In prenatal care, there was a decrease in elective consultations; increased time between consultations; delayed care due to paramentation; implementation of new hygiene protocols; limitation of the number of companions; creation of new environments such as the Covid-19 isolation room for symptomatic pregnant women; teleservice and work overload due to the increased demand coming from Primary Health Care. In childbirth/postparum, the reports indicated a reduction in the number of beds; testing and isolation of symptomatic patients; limitating walking, restriction of companions and mandatory use of mask by pregnant woman. Conclusion: the restructuring of services and the creation of new spaces to care for patients with Covid-19 led to a reduction in the availability of vacancies for prenatal and postpartum consultations. The changes were accompanied by new service rules, with setbacks regarding the guarantee of rights.

Acolhimento ao parto em estabelecimentos de saúde vinculados à Rede Cegonha no Brasil: a perspectiva das usuárias / Childbirth care in health services affiliated with the Stork Network in Brazil: the users' perspective / Acogida al parto en establecimientos de salud vinculados a la Red Cegonha en Brasil: la perspectiva de las usuarias

Este estudo objetivou analisar os fatores sociodemográficos e reprodutivos associados ao acolhimento ao parto em estabelecimentos de saúde vinculados à Rede Cegonha no Brasil, na perspectiva das usuárias. Foram selecionados 606 serviços com amostra de 10.540 puérperas. O desfecho foi a variável latente acolhimento da puérpera, composta por cinco indicadores: apresentação dos profissionais com nome e função, chamar a gestante pelo nome, compreensão das informações dadas, se sentir bem tratada e respeitada e ter as necessidades respondidas pela equipe. As variáveis explicativas foram: idade, escolaridade, cor da pele, situação conjugal, tipo de parto, paridade e peregrinação. Foi utilizada modelagem de equações estruturais. Observaram-se maiores percentuais de mulheres com idade de 20 a 34 anos (68,31%), que se autodeclararam como pardas (56,3%), com escolaridade entre 9 e 11 anos de estudo (56,1%) e que tinham companheiro (78,8%). Houve predominância de puérperas que tiveram parto vaginal (56,6%), com um a dois filhos (46%) e que relataram não peregrinar (91,9%). Apresentaram efeito direto positivo sobre o acolhimento mulheres com maior idade (CP = 0,094; p < 0,001) e maior escolaridade (CP = 0,096; p < 0,001). O parto cesáreo apresentou efeito direto negativo (CP = -0,059; p < 0,002) e cor da pele preta e parda apresentou efeitos direto e indireto negativos (CP = -0,081; p < 0,001 e CP = -0,014; p < 0,001). Puérpera com maior idade, maior escolaridade e que tiveram parto vaginal tiveram percepção mais positiva do acolhimento nos serviços de saúde.

This study aimed to analyze sociodemographic and reproductive factors associated with childbirth care in health services affiliated with the Stork Network in Brazil, from the users' perspective. The sample included 10,540 postpartum women from 606 services. The outcome was the latent variable reception of the patient, consisting of five indicators: healthcare staff members introducing themselves stating their names and roles, calling the pregnant woman by her name, the patient's understanding of the information provided, the patient feeling well treated and respected, and the patient having her needs met by the staff. The explanatory variables were maternal age, schooling, skin color, marital status, type of delivery, parity, and number of services visited before admission for childbirth. Most of the women were 20 to 34 years of age (68.31%), self-identified as brown (56.3%), had 9 to 11 years of schooling (56.1%), and were married or lived with the partner (78.8%). There was a predominance of vaginal delivery (56.6%), with one or two previous children (46%), and reports of not having gone to more than one maternity service to be admitted (91.9%). There was a direct positive effect on reception for childbirth from patient´s higher age (SC = 0.094; p < 0.001) and more schooling (SC = 0.096; p < 0.001). Cesarean delivery had a direct negative effect (SC = -0.059; p < 0.002), and black and brown skin color had direct and indirect negative effects (SC = -0.081; p < 0.001 and SC = -0.014; p < 0.001). Older postpartum women and those with more schooling and vaginal delivery had a more positive perception of their reception by maternity services.

El objetivo de este estudio fue analizar los factores sociodemográficos y reproductivos, asociados a la acogida en el parto, en establecimientos de salud vinculados a la Red Cegonha en Brasil, desde la perspectiva de las usuarias. Se seleccionaron 606 servicios en una muestra de 10.540 puérperas. El resultado fue la variable latente de acogida de la puérpera, compuesta por cinco indicadores: presentación de los profesionales con nombre y función, llamar a la gestante por el nombre, comprensión de la información proporcionada, sentirse bien tratada y respetada y contar con las necesidades cubiertas por el equipo. Las variables explicativas fueron: edad, escolaridad, color de piel, situación conyugal, tipo de parto, paridad y desplazamientos largos. Se utilizó un modelado de ecuaciones estructurales. Se observaron mayores porcentajes de mujeres con una edad comprendida entre los 20 a los 34 años (68,31%), que se autodeclararon mestizas (56,3%), con una escolaridad entre 9 y 11 años de estudio (56,1%) y que tenían compañero (78,8%). Hubo una predominancia de puérperas que tuvieron un parto vaginal (56,6%), con de 1 a 2 hijos (46%) y que informaron no realizar grandes desplazamientos (91,9%). Presentaron un efecto directo positivo sobre la acogida mujeres con mayor edad (CP = 0,094; p < 0,001) y mayor escolaridad (CP = 0,096; p < 0,001). El parto por cesárea presentó un efecto directo negativo (CP = -0,059; p < 0,002) y color de la piel negra y mestiza presentó efectos directo e indirecto negativos (CP = -0,081; p < 0,001 e CP = -0,014; p < 0,001). Puérperas con mayor edad, mayor escolaridad y que tuvieran parto vaginal tuvieron una percepción más positiva de acogida en los servicios de salud.

Challenges at the front: experiences of professionals in admitting patients to the intensive care unit during the covid-19 pandemic / Desafíos delanteros: experiencias de profesionales en el ingreso de pacientes en la unidad de cuidados intensivos en la pandemia del covid-19 / Desafios do front: experiências de profissionais na admissão de pacientes em unidade de terapia intensiva na pandemia da covid-19

ABSTRACT Objective: to know the perspectives, practices and challenges in decision-making for admitting patients into the Intensive Care Unit during the Covid-19 pandemic. Methods: a qualitative study developed in two public hospitals in Maranhão, Brazil, from November/2020 to January/2021. Data collection took place through individual interviews guided by a script. A total of 22 professionals participated in the study: nurses and doctors who worked in the Intensive Care Unit and Bed Regulation in the first wave of the pandemic. Content Analysis was used in the thematic mode, with support from the Qualitative Data Analysis software program for data categorization. The theory of Responsibility for Reasonableness guided the study. Results: two main categories emerged: "The context of the decision-making process - the paradox of celestial discharges" and "Decision-making for admission". In the scenario of high demand, a lack of beds, and the uncertainties of the "new disease", deciding who would occupy the bed was arduous and conflicting. Clinical and non-clinical criteria such as severity, chance of survival, distance to be covered and transport conditions were considered. It was found that the ambivalence of feelings attributed to death and care at that moment of the pandemic marked the social and technical environment of intensive care. Conclusions: the complexity of the decision-making process for admission to an intensive care unit was evidenced, demonstrating the importance of analyzing the allocation of critical resources in pandemic scenarios. Knowing the perspectives of professionals and their reflections on the experiences in that period can help in planning the allocation of health resources in future emergency scenarios.

RESUMEN Objetivo: conocer perspectivas, prácticas y desafíos en la toma de decisiones para el ingreso de pacientes a camas en Unidades de Cuidados Intensivos en la pandemia de COVID-19. Métodos: un estudio cualitativo, desarrollado en dos hospitales públicos de Maranhão, Brasil, de noviembre/2020 a enero/2021. La recolección de datos se realizó a través de entrevistas individuales guiadas por un guión. Un total de 22 profesionales participaron en el estudio: enfermeros y médicos que actuaban en la Unidad de Cuidados Intensivos y Regulación de Camas en la primera ola de la pandemia. Se utilizó el Análisis de Contenido en la modalidad temática, con apoyo del Software de Análisis Cualitativo de Datos para la categorización de los datos. La teoría de la Responsabilidad por la Razonabilidad guió el estudio. Resultados: surgieron dos categorías principales: "El contexto del proceso de toma de decisiones - la paradoja de los altos celestes" y "Toma de decisiones para la admisión". En el escenario de alta demanda, escasez de camas e incertidumbres de la "nueva enfermedad", decidir quién ocuparía la cama fue arduo y conflictivo. Se consideraron criterios clínicos y no clínicos, como gravedad, probabilidad de supervivencia, distancia a recorrer y condiciones de transporte. Se constató que la ambivalencia de los sentimientos atribuidos a la muerte y al cuidado, en ese momento de la pandemia, marcaron el ambiente social y técnico de la terapia intensiva. Conclusiones: se evidenció la complejidad del proceso de toma de decisiones para el ingreso a una unidad de cuidados intensivos, demostrando la importancia de analizar la asignación de recursos críticos en escenarios de pandemia. Conocer las perspectivas de los profesionales y sus reflexiones sobre las experiencias en ese período puede ayudar en la planificación de la asignación de recursos de salud en futuros escenarios de emergencia.

RESUMO Objetivo: conhecer perspectivas, práticas e desafios na tomada de decisão para admissão de pacientes em leitos de Unidades de Terapia Intensiva na pandemia da Covid-19. Métodos: estudo qualitativo, desenvolvido em dois hospitais públicos do Maranhão, Brasil, de novembro/2020 a janeiro/2021. A coleta de dados ocorreu por meio de entrevistas individuais guiadas por roteiro. Participaram do estudo 22 profissionais: enfermeiros e médicos que atuaram em Unidade de Terapia Intensiva e Regulação de Leitos na primeira onda da pandemia. Empregou-se a Análise de Conteúdo na modalidade temática, com apoio do Qualitative Data Analysis Software para categorização dos dados. A teoria da Responsabilidade pela Razoabilidade norteou o estudo. Resultados: emergiram duas categorias principais: "Contexto do processo decisório - o paradoxo das altas celestiais" e "Tomada de decisão para admissão". No cenário de alta demanda, insuficiência de leitos e de incertezas da "nova doença", decidir quem ocuparia o leito era árduo e conflitante. Critérios clínicos e não clínicos, como gravidade, chance de sobrevivência, distância a ser percorrida e condições do transporte foram considerados. Constatou-se que a ambivalência de sentimentos atribuídos à morte e ao cuidado, naquele momento da pandemia, marcaram o ambiente social e técnico da terapia intensiva. Conclusões: evidenciou-se a complexidade do processo decisório para admissão em unidade de terapia intensiva, demonstrando a importância de analisar a alocação de recursos críticos em cenários pandêmicos. Conhecer as perspectivas dos profissionais e as reflexões deles sobre as experiências naquele período podem auxiliar no planejamento de alocação de recursos de saúde em cenários emergenciais futuros.

Diagnostic Errors in Wilms' Tumors: Learning From Our Mistakes.

Aim: This study aimed to analyze clinical characteristics and image findings in patients initially diagnosed with renal masses and treated on the Société Internationale d'Oncologie Pédiatrique (SIOP) 2001 protocol for Wilms tumor (WT) that eventually were diagnosed with different pathologies. Methods: We reviewed the preoperative symptoms, laboratory tests, and images of patients who were initially treated for WT and proved to have other diagnoses. Data from these patients were compared to those of the last 10 patients with WT and the last 10 patients with neuroblastoma (NBL) treated at a single institution. Results: From June 2001 to December 2020, we treated 299 patients with NBL and 194 with WT. Five patients treated with preoperative chemotherapy for WT were postoperatively diagnosed with NBL (one patient had bilateral renal masses and one with multifocal xanthogranulomatous pyelonephritis). Three underwent nephrectomy, two biopsies only, and one adrenalectomy due to intraoperative characteristics. Regarding clinical presentation, abdominal mass or swelling was very suggestive of WT (p = 0.011); pain, although very prevalent in the study group (67%), was not statistically significant, as well as intratumoral calcifications on computed tomography (CT) (67%). Urinary catecholamines were elevated in all patients mistreated for WT with the exception of the patient with pyelonephritis in which it was not collected. Conclusion: Some pathologies can be misdiagnosed as WT, especially when they present unspecified symptoms and dubious images. Diagnostic accuracy was 98.1%, which highlights the quality of the multidisciplinary team. Abdominal mass or swelling is highly suggestive of WT, especially in the absence of intratumoral calcifications on CT. If possible, urinary catecholamines should be collected at presentation as they help in the differential diagnosis of NBL.

Molecular profiling of pediatric and adolescent ependymomas: identification of genetic variants using a next-generation sequencing panel.

PURPOSE: Ependymoma (EPN) accounts for approximately 10% of all primary central nervous system (CNS) tumors in children and in most cases, chemotherapy is ineffective and treatment remains challenging. We investigated molecular alterations, with a potential prognostic marker and therapeutic target in EPNs of childhood and adolescence, using a next-generation sequencing (NGS) panel specific for pediatric neoplasms. METHODS: We selected 61 samples with initial diagnosis of EPN from patients treated at Pediatric Oncology Institute-GRAACC/UNIFESP. All samples were divided according to the anatomical compartment of the CNS - 42 posterior fossa (PF), 14 supratentorial (ST), and five spinal (SP). NGS was performed to identify somatic genetic variants in tumor samples using the Oncomine Childhood Cancer Research Assay® (OCCRA®) panel, from Thermo Fisher Scientific®. RESULTS: Genetic variants were identified in 24 of 61 (39.3%) tumors and over 90% of all variants were pathogenic or likely pathogenic. The most commonly variants detected were in CIC, ASXL1, and JAK2 genes and have not been reported in EPN yet. MN1-BEND2 fusion, alteration recently described in a new CNS tumor type, was identified in one ST sample that was reclassified as astroblastoma. Additionally, YAP1-MAMLD1 fusion, a rare event associated with good outcome in ST-EPN, was observed in two patients diagnosed under 2 years old. CONCLUSIONS: Molecular profiling by the OCCRA® panel showed novel alterations in pediatric and adolescent EPNs, which highlights the clinical importance in identifying genetic variants for patients' prognosis and therapeutic orientation.

Prevalence and factors associated with unplanned pregnancy in a Brazilian capital in the Northeast / Prevalência e fatores associados à gravidez não planejada em uma capital do Nordeste Brasileiro

Abstract Objectives: to analyze the prevalence and factors associated with unplanned pregnancy in a Brazilian capital in the Northeast. Methods: a cross-sectional study nested to a hospital birth cohort with a probable sample of 5,110 puerperal women. Associated factors were analyzed using a hierarchical theoretical model in three levels: distal (women's socioeconomic and demographic characteristics), intermediate (reproductive characteristics, maternal habits and BMI), and proximal level (partner's characteristics). Multivariate Poisson regression analysis was performed. Results: the prevalence of unplanned pregnancy was 68.1% (CI95%=66.8-69.4). Multivariate analysis showed association with black skin color/race (PR=1.03; CI95%=1.01- 1.07), mother's age group up to 19 years old (PR=1.09; CI95%=1.06-1.12) and 20 to 24 years old (PR=1.04; CI95%=1.01-1.07), not living with partner (PR=1.09; CI95%=1.07- 1.11), highest number of people in the household: 5 people (PR= 1.10; CI95%=1.08-1.13) and 3 to 4 (PR=1.08; CI95%=1.05-1.10), number of ≥4 children (PR=1.09; CI95%=1.06- 1.13) and 2 or 3 children (PR=1.03; CI95%=1.02-1.05), alcohol consumption (PR=1.03; CI95%=1.01-1.05), malnourished pre-pregnancy BMI (PR=1.03; CI95%=1.01-1.06) and partner's low schooling (5 to 8 years) (PR=1.03; CI95%=1.01-1.07). Prior abortion was inversely associated with planned pregnancy (PR=0.95; CI95%=0.93-0.97). Conclusions: the prevalence of unplanned pregnancy was high and was associated with socioeconomic and demographic characteristics that reflect on the combination of the complex inequalities that impact women and their partners

Resumo Objetivos: analisar a prevalência e fatores associados à gravidez não planejada em uma capital do Nordeste brasileiro. Métodos: estudo transversal aninhado à coorte de nascimento hospitalar com amostra probabilística de 5.110 puérperas. Fatores associados foram analisados utilizando-se modelo teórico hierarquizado em três níveis: distal (caracteristicas socioeconômicas e demográficas da mulher), intermediário(caracteristicas reprodutivas, hábitos maternos e IMC), e nível proximal (características do companheiro). Realizou-se análise de regressão multivariada de Poisson. Resultados: a prevalência de gravidez não planejada foi de 68,1% (IC95%= 66,8-69,4). A análise multivariada mostrou associação com cor/raça preta (RP=1,03; IC95%= 1,01-1,07), faixa etária da mãe até 19 anos (RP=1,09; IC95%= 1,06-1,12) e 20 a 24 anos (RP=1,04; IC95%= 1,01-1,07), não residir com o companheiro (RP=1,09; IC95%= 1,07-1,11), maior o número de pessoas no domicílio: 5 pessoas (RP= 1,10; IC95%= 1,08-1,13) e de 3 a 4 (RP=1,08; IC95%= 1,05-1,10), número de ≥4 filhos (RP=1,09; IC95%= 1,06-1,13) e 2 ou 3 filhos (RP=1,03; IC95%= 1,02-1,05), uso de álcool (RP=1,03; IC95%= 1,01-1,05), IMC pré-gestacional desnutrido (RP=1,03; IC95%= 1,01-1,06) e baixa escolaridade (5 a 8 anos) do companheiro (RP=1,03; IC95%= 1,01-1,07). O aborto prévio associou-se inversamente com gravidez planejada (RP=0,95; IC95%= 0,93-0,97). Conclusões: foi elevada a prevalência de gravidez não planejada, e esteve associada a características socioeconômicas e demográficas que refletem a combinação de complexas desigualdades que impactam mulheres e seus parceiros.
