Abstract Studies investigating the effects of different modalities of exercises on the immune system are scarce. Therefore, the aim of this study was to compare the effects of eight weeks of resistance and aerobic training on the proliferation of T and B lymphocytes from mice. Eighteen male C56BL6/J mice were divided into groups (n=6), sedentary, aerobic, and resistance training. After 8 weeks, animals were euthanized, and their splenocytes were labeled and cultured with and without stimulation. Lymphocyte proliferation (CD4+, CD8+ and CD21/CD35+) was evaluated by flow cytometry. The mice subjected to resistance exercise exhibited greater proliferation for total, CD8+ and B lymphocytes (p<0.05), but not CD4+ cells (p>0.05), compared with their sedentary counterparts. We found significant correlations between maximum load and total, CD8+ and B lymphocytes proliferation rates (p<0.05). In conclusion, our results showed that resistance training promoted an improvement in the immune response associated with CD8+ and B lymphocytes.

ABSTRACT Purpose To identify the pathophysiological definitions adopted by studies investigating “cochlear synaptopathy” (CS) and “hidden hearing loss” (HHL). Research strategies The combination of keywords “Auditory Synaptopathy” or “Neuronal Synaptopathy” or “Hidden Hearing Loss” with “etiology” or “causality” or “diagnosis” was used in the databases EMBASE, Pubmed (MEDLINE), CINAHL (EBSCO), and Web of Science. Selection criteria Studies that investigated CS or HHL in humans using behavioral and/or electrophysiological procedures were included. Data analysis Data analysis and extraction were performed with regard to terminology, definitions, and population. Results 49 articles were included. Of these, 61.2% used the CS terminology, 34.7% used both terms, and 4.1% used HHL. The most-studied conditions were exposure to noise and tinnitus. Conclusion CS terminology was used in most studies, referring to the pathophysiological process of deafferentiation between the cochlear nerve fibers and inner hair cells.

ABSTRACT Purpose To compare the speech and voice patterns of myasthenia gravis (MG) patients over four years, and correlate the results with clinical aspects of the disease. Methods Data was collected for 4 years. The clinical assessment tools included the Quantitative Myasthenia Gravis (QMG) score, the Myasthenia Gravis Foundation of America (MGFA) clinical classification, and the Myasthenia Gravis Quality of Life 15-item Scale (MG-QoL). To assess speech, the recorded speaking tasks were analyzed acoustically and given auditory-perceptual ratings. Sex (equal distribution) and age (p=0.949) were used as matching criteria in the final sample, which consisted of 10 individuals in the MG group (MGG) and 10 individuals in the control group (CG). Results After 4 years, the MG participants presented stable health status, increased mild and moderate dysarthria (from 40% to 90% of the subjects), and a significant deterioration in the respiration, phonation, and articulation subsystems. The acoustic analysis showed a decline in articulatory patterns (speech rate p=0.047, articulation rate p=0.007, mean syllable duration p=0.007) and vocal quality (increased jitter p=0.022). In the follow-up comparison, there was a significant difference between the phonation variables (shimmer and harmonic-to-noise ratio) of the MGG and CG. Conclusion The MG patients presented a decline in speech over four years and an increase in mild and moderate dysarthria. Despite presenting stable health status, their respiratory, phonatory, and articulatory subsystems worsened. There was no correlation between speech patterns and clinical characteristics of the disease (severity and motor scale).

RESUMO Objetivo Comparar o padrão de fala e voz de indivíduos com Miastenia Gravis (MG) em um intervalo de quatro anos e correlacionar com aspectos clínicos da doença. Método A coleta de dados foi realizada ao longo de 4 anos. A avaliação clínica foi composta pelo Quantitative Myasthenia Gravis Score (QMGS), pela Myasthenia Gravis Foundation of America Classification (MGFA) e pela escala de qualidade de vida para Miastenia Gravis (MG-QOL). A avaliação da fala foi composta por gravação de tarefas, análise perceptivo-auditiva e análise acústica. A amostra final foi composta por 10 indivíduos em MG e 10 indivíduos no grupo controle (GC), pareados por sexo (distribuição igualitária) e idade (p=0,949). Resultados Após 4 anos, os indivíduos com MG apresentaram estabilidade clínica, aumento do diagnóstico de disartria leve e moderada (de 40% para 90% dos sujeitos) e diminuição significativa no desempenho dos subsistemas da fala: respiração, fonação e articulação. Na análise acústica, houve declínio do padrão articulatório (taxa de fala p=0,047, taxa de articulação p=0,007, duração média das sílabas p=0,007) e qualidade vocal (jitter aumentado p=0,022). Houve diferença significativa nas variáveis fonatórias (shimmer e harmonic-to-noise ratio) entre os grupos MG e GC na comparação do seguimento. Conclusão Indivíduos com MG apresentaram declínio no padrão de fala em um intervalo de quatro anos, com aumento no número de disártricos (leve e moderado). Mesmo com a estabilidade da doença, houve piora dos subsistemas respiratório, fonatório e articulatório. Não houve correlação entre o padrão de fala e as características clínicas da doença (gravidade e escala motora).

Objectives: To examine drug overdose records in Brazil from 2000 to 2020, analyzing trends over time in overdoses and overall sociodemographic characteristics of the deceased. Methods: Using data from the Brazilian Mortality Information System (Sistema de Informações sobre Mortalidade), we identified records from 2000-2020 in which the underlying cause-of-death was one of the following codes: X40-X45 (accidental poisoning), X60-X65 (intentional poisoning), or Y10-Y15 (undetermined intentionality poisoning). The Brazilian dataset included 21,410 deaths. We used joinpoint regression analysis to assess changes in trends over time. Results: People who died of drug overdoses in Brazil between 2000 and 2020 had a mean age of 38.91 years; 38.45% were women, and 44.01% were identified as White. Of the overdose deaths, 44.70% were classified as intentional and 32.12% were classified as unintentional. Among the identified drugs, stimulants were the most common class. However, most records did not report which drug was responsible for death. Conclusion: Sociodemographic trends in overdose deaths in Brazil must guide country-specific policies. Nevertheless, data collection protocols must be improved, particularly regarding the drug used in overdoses.

ABSTRACT: The objective of this study was to verify the impact of early childhood caries (ECC) and parental oral health literacy (OHL) on the use of oral health care services by preschool children. A population-based study was conducted with 449 dyads of preschool children aged 4-6 years and their parents/caregivers in the city of Ribeirão das Neves, Brazil. Two examiners performed the diagnosis of ECC using the International Caries Detection and Assessment System (ICDAS- Epi). The Brazilian version of the Hong Kong Oral Health Literacy Assessment Task for Pediatric Dentistry was administered to measure parents’ OHL. Parents/caregivers answered the question “When was your child’s last visit to the dentist?” to measure the use of oral health care services by the preschool children. The multiple logistic regression (p<0.05) revealed that children with presence of cavitated caries lesions were 1.82-fold more likely to use oral health care services (OR=1.82; 95%CI: 1.23-2.70) compared to those with absence of cavitated caries lesions. Children whose parents/caregivers had lower OHL were 34 % less likely to use oral health care services compared to those whose parents had higher OHL (OR=0.66; 95%CI: 0.45-0.99). Preschool children Dental services are used more by preschool children with presence of cavitated caries lesions and whose parents/caregivers have higher scores of OHL.

RESUMEN: El objetivo de este estudio fue verificar el impacto de la caries de la primera infancia (CPI) y la alfabetización en salud oral de los padres (ASB) en el uso de los servicios de salud oral por parte de los niños en edad preescolar. Se realizó un estudio de base poblacional con 449 díadas de preescolares de 4 a 6 años y sus padres/cuidadores en la ciudad de Ribeirão das Neves, Brasil. Dos examinadores realizaron el diagnóstico de CPI utilizando el Sistema Internacional de Evaluación y Detección de Caries (ICDAS-Epi). Se administró la versión brasileña de Hong Kong Oral Health Literacy Assessment Task for Pediatric Dentistry para medir la ASB de los padres. Los padres/cuidadores respondieron la pregunta "¿Cuándo fue la última visita de su hijo al dentista?" medir la utilización de los servicios de salud oral por parte de los preescolares. La regresión logística múltiple (p<0,05) reveló que los niños con presencia de lesiones de caries cavitadas tenían 1,82 veces más probabilidades de utilizar los servicios de salud oral (OR=1,82; IC95%: 1,23-2,70) en comparación con aquellos con ausencia de lesiones de caries cavitadas. Los niños cuyos padres/cuidadores tenían un ASB más bajo tenían un 34 % menos de probabilidades de utilizar los servicios de atención de la salud bucodental en comparación con aquellos cuyos padres tenían un ASB más alto (OR = 0,66; IC del 95%: 0,45-0,99). Los servicios dentales para niños en edad preescolar son utilizados con mayor frecuencia por niños preescolares con presencia de lesiones cariosas cavitadas y cuyos padres/cuidadores tienen puntuaciones más altas de ASB.

ABSTRACT Introduction: Patients on renal replacement therapy (RRT) and kidney transplant recipients (KTR) present multiple factors that may increase the risk of death from coronavirus disease 2019 (COVID-19). This study aimed to evaluate the incidence and impact of COVID-19 in RRT patients and KTRs. Methods: Between March 2020 and February 2021, we monitored the RRT population of thirteen dialysis facilities that refer patients for transplantation to our center, a tertiary hospital in Southern Brazil. In the same period, we also monitor COVID-19 incidence and mortality in our KTR population. Demographical, clinical, and COVID-19-related information were analyzed. Results: We evaluated 1545 patients in the dialysis centers, of which 267 (17.4%) were infected by COVID-19 and 53 (19.9%) died. Among 275 patients on the kidney transplant waiting list, 63 patients (22.9%) were infected and seven (11.1%) died. COVID-19 was the leading cause of death (29.2%) among patients on the waiting list. Within the population of 1360 KTR, 134 (9.85%) were diagnosed with COVID-19 and 20 (14.9%) died. The number of kidney transplants decreased by 56.7% compared with the same period in the previous twelve months. Conclusion: In the study period, patients on RRT and KTRs presented a high incidence of COVID-19 and high COVID-19-related lethality. The impact on the patients on the transplant waiting list was less pronounced. The lethality rate observed in both cohorts seems to be related to age, comorbidities, and disease severity.

Resumo Introdução: Pacientes em terapia renal substitutiva (TRS) e receptores de transplante renal (RTR) apresentam múltiplos fatores que podem aumentar o risco de óbito por doença do coronavírus 2019 (COVID-19). Este estudo teve como objetivo avaliar incidência e impacto da COVID-19 em pacientes em TRS e RTR. Métodos: Entre Março de 2020 e Fevereiro de 2021, monitoramos a população em TRS de treze unidades de diálise que encaminham pacientes para transplante ao nosso centro, um hospital terciário no Sul do Brasil. No mesmo período, também monitoramos a incidência e mortalidade da COVID-19 em nossa população de RTR. Foram analisadas informações demográficas, clínicas e relacionadas à COVID-19. Resultados: Avaliamos 1545 pacientes nos centros de diálise, dos quais 267 (17,4%) foram infectados pela COVID-19 e 53 (19,9%) foram a óbito. Entre 275 pacientes na lista de espera para transplante renal, 63 (22,9%) foram infectados e sete (11,1%) foram a óbito. COVID-19 foi a principal causa de óbito (29,2%) entre pacientes na lista de espera. Dentre a população de 1360 RTR, 134 (9,85%) foram diagnosticados com COVID-19 e 20 (14,9%) foram a óbito. O número de transplantes renais diminuiu em 56,7% comparado ao mesmo período nos doze meses anteriores. Conclusão: No período do estudo, pacientes em TRS e RTR apresentaram alta incidência de COVID-19 e alta letalidade relacionada à COVID-19. O impacto nos pacientes na lista de espera para transplante foi menos pronunciado. A taxa de letalidade observada em ambas as coortes parece estar relacionada à idade, comorbidades e gravidade da doença.

Abstract In recent years, there has been a growing scientific interest in the field of human-animal interaction, and the results have suggested several potential benefits in both adults and children. Dogs can play an important role in children's social, emotional and cognitive development. Playing with the dog can also contribute to increase children's physical activity, improving their quality of life. However, it is undeniable that there are unfavorable effects or risks that must be considered. The most frequently mentioned are allergy, asthma and transmission of zoonotic diseases. In addition, risks such as aggression and bites must also be considered. It has been studied whether the age of exposure to the dog can influence the risk of allergic disease, and there are not enough data. There is no evidence to support the existence of hypoallergenic species. The physician must inform the family of all the risks and benefits associated with owning a dog, contributing to an informed and conscious parental decision. It is also advisable to carefully select the dog, taking into account its intrinsic characteristics, namely aggressiveness. Factors such as available daily time, adequate space, caregivers for periods of absence and economic availability should also be considered.

Resumo Nos últimos anos, tem havido um interesse científico crescente no campo da interação homem-animal, e os resultados têm sugerido vários potenciais benefícios, tanto em adultos como em crianças. Os cães podem desempenhar um papel importante no desenvolvimento social, emocional e cognitivo das crianças. Brincar com o cão pode também contribuir para aumentar a atividade física das crianças melhorando a sua qualidade de vida. No entanto, é inegável que existem efeitos desfavoráveis ou riscos que devem ser considerados. As preocupações mais frequentemente referidas são alergia, asma e transmissão de doenças zoonóticas. Além disso, riscos tais como agressões e mordeduras também devem ser considerados. Tem estado a ser estudado se a idade de exposição ao cão pode influenciar o risco de doença alérgica, não existindo dados suficientes. Não há evidência que suporte a existência de espécies hipoalergénicas. O médico deve informar a família de todos os riscos e benefícios associados à posse de um cão, contribuindo para uma decisão parental informada e consciente. É também aconselhável selecionar cuidadosamente o cão, tendo em conta as suas características intrínsecas, nomeadamente a agressividade. Fatores como o tempo diário disponível, espaço adequado, prestadores de cuidados para períodos de ausência e disponibilidade económica também devem ser ponderados.

ABSTRACT Objective: Intrauterine environment can induce fetal metabolic programming that predisposes to adiposity-related chronic diseases in its lifespan. We examined the associations of parental nutritional status and gestational weight gain with offspring body composition in early adulthood. Materials and methods: This is cross-sectional analysis of female participants of the NutriHS who were submitted to questionnaires, clinical examinations and body composition assessed by DXA. Association of pre-conception parental BMI and maternal gestational weight gain (exposures) with body composition measurements (outcomes) were analyzed using multiple linear models adjusted for Directed Acyclic Graphs-based covariables (maternal and paternal educational level, maternal age, and tobacco, alcohol and/or drugs use). The sample included 124 women (median 28 (24-31) years) with a mean BMI of 25.4 ± 4.7 kg/m2. Results: No association between previous paternal BMI and offspring’s body composition was detected. In the fully adjusted linear regression model, maternal BMI was associated with offspring’s total lean mass (β = 0.66, p = 0.001), appendicular skeletal muscle mass index (ASMI) (β = 0.11, p = 0.003) and fat mass index (FMI) (β = 0.03, p = 0.039). Gestational weight gain was associated with increased offspring’s BMI (OR 1.12 [95% CI 1.02-1.20], p = 0.01). The linear regression model adjusted for maternal age and maternal and paternal education levels showed associations of gestational weight gain with offspring’s ASMI (β = 0.42, p = 0.046), FMI (β = 0.22, p = 0.005) and android-to-gynoid fat ratio (β = 0.09, p = 0.035). Conclusion: Our findings suggest that preconception maternal BMI could influence lean mass and general adiposity of young adult female offspring and that gestational weight gain could be useful for predicting centrally distributed adiposity.

Abstract Objective: To assess the predictive value of selected growth phenotypes for neonatal morbidity and mortality in preterm infants < 30 weeks and to compare them with INTERGROWTH-21st (IG21). Methods: Retrospective analysis of data from the Brazilian Neonatal Research Network (BNRN) database for very low birth weight (VLBW) at 20 public tertiary-care university hospitals. Outcome: the composite neonatal morbidity and mortality (CNMM) consisted of in-hospital death, oxygen use at 36 weeks, intraventricular hemorrhage grade 3 or 4, and Bell stage 2 or 3 necrotizing enterocolitis. Selected growth phenotypes: small-for-gestational-age (SGA) defined as being < 3rd (SGA3) or 10th (SGA10) percentiles of BW, and large-for-gestational-age (LGA) as being > 97th percentile of BW. Stunting as being < 3rd percentile of the length and wasting as being < 3rd percentile of BMI. Single and multiple log-binomial regression models were fitted to estimate the relative risks of CNMM, comparing them to IG21. Results: 4,072 infants were included. The adjusted relative risks of CNMM associated with selected growth phenotypes were (BNRN/IG21): 1.45 (0.92–2.31)/1.60 (1.27–2.02) for SGA; 0.90 (0.55–1.47)/1.05 (0.55–1.99) for LGA; 1.65 (1.08–2.51)/1.58 (1.28–1.96) for stunting; and 1.48 (1.02–2.17) for wasting. Agreement between the two references was variable. The growth phenotypes had good specificity (>95%) and positive predictive value (70-90%), with poor sensitivity and low negative predictive value. Conclusion: The BNRN phenotypes at birth differed markedly from the IG21 standard and showed poor accuracy in predicting adverse neonatal outcomes.

ABSTRACT: Aim: To analyze the trend of neonatal mortality in Brazil from 2015 to 2019 and its preventable causes. Methods: Ecological time-series study with data extracted from the Mortality Information System and Live Births Information System. Neonatal mortality rates were calculated overall and according to preventable causes. Trend analysis was performed by Prais-Winsten regression. Results: The overall neonatal mortality rate reduced from 8.78 in 2015 to 8.60 in 2019. Disparities in neonatal mortality rates were observed among regions, with higher rates in the northern (10.3/1,000) and northeastern (9.9/1,000) regions. The causes preventable by adequate care for pregnancy, delivery and neonatal care prevailed, together totaling 97.8% of neonatal deaths in the period. There was a decreasing trend in preventable causes due to adequate care of the newborn (p < 0.001). Conclusion: There was a decrease in the neonatal mortality rate in Brazil from 2015 to 2019.

ABSTRACT Objective: To evaluate radiological (gestational and perinatal) and neonatal signs of patients with Patau syndrome and semilobar holoprosencephaly, as well as to report the association of both pathologies. Case description: This case report is about a female infant, born at term with trisomy of the chromosome 13 and semilobar holoprosencephaly, with thalamic fusion and a single cerebral ventricle, in addition to several other changes that worsened the patient's prognosis. Comments: Chromosome 13 trisomy is a genetic alteration that leads to the symptoms that determines Patau syndrome. In this syndrome, cardiovascular, urogenital, central nervous system, facial structure and intellectual impairment are common, in addition to problems in limb formation, such as decreased humerus and femur length, polydactyly, hypotelorism and low ear implantation. It is estimated, however, that holoprosencephaly is present in only 24 to 45% of the patients with trisomy 13.

RESUMO Objetivo: Avaliar sinais radiológicos (gestacionais e perinatais) e neonatais de paciente com síndrome de Patau e holoprosencefalia semilobar, assim como relatar a associação de ambas as patologias. Descrição do caso: Trata-se de um relato de recém-nascido do sexo feminino a termo, que apresentou trissomia do cromossomo 13 e holoprosencefalia semilobar, com fusão talâmica e ventrículo cerebral único, além de várias outras alterações que pioraram o prognóstico da paciente. Comentários: A trissomia do cromossomo 13 é um defeito genético que caracteriza um conjunto de sintomas que compõem a Síndrome de Patau. Nesta síndrome, é comum o acometimento cardiovascular, urogenital, do sistema nervoso central, da estrutura facial e da capacidade intelectual, além de falhas na formação dos membros, como diminuição no comprimento do úmero, fêmur, polidactilia, hipotelorismo e baixa implantação das orelhas. Estima-se, no entanto, que a holoprosencefalia apresente-se nesse grupo de malformações congênitas apenas em 24 a 45% dos casos.

Abstract Mass movements naturally occurring along slopes, especially after heavy rains, cause heavy losses of materials and life and affect highways, pipelines, and bridges, among other structures. Among the most common mass movements, landslides and subsequent mass flows especially stand out. Remote sensing and geoprocessing techniques are useful tools for geological and geotechnical analysis, here applied to characterization of mass movements from the analysis of the influence of slopes, lineaments or fractures, and geological-geotechnical at the junction of the Curral homocline and the Moeda syncline, Quadrilátero Ferrífero, Southeast Brazil. The area consists of Archean granitic-gneissic basement and the greenstone belt sequence of the Rio das Velhas Supergroup with Proterozoic metasedimentary rocks of the Minas Supergroup covering these two older successions. Based on satellite images, a preliminary map of lineaments was created, and fractures were grouped according to their direction before being rasterized. Each lineament group was associated with a previously known geological and/or structural feature. Geological units mapped in the area were numerically classified according to their mass movement susceptibility and related geotechnical units. Using a Shuttle Radar Topography Mission (SRTM) image, a terrain slope raster was generated. The objective was to obtain a raster indicating low and high probabilities of mass movements. Four sets of lineaments were identified: the first set associated with the northeast strike stratification of the rocks of the Moeda Formation; the second set related to eastward-trending warp axis lineations; the third set related to the southeast trend of stretch lineaments or mafic dykes directions; and the fourth set evidently associated with the watershed pattern of the Curral Range crest, perpendicular to the strike of the rocks in the area. Simulations with different combinations of parameters produced eight scenarios were generated were constructed to classify the area as to its susceptibility to rupture through changes in slope, lithotype, and lineament density; the first four (1 to 4) were classified by using the slope percentage raster without interval reclassification, so its values in the cartographic algebra were not grouped. The last for (5 to 8), consider the slope percentage classified. This methodology successfully combines mathematical models for predicting mass movements and determining areas in the urban landscape most susceptible to these phenomena. As such, it comprises a useful tool for government planning of preventative actions for areas of high risk.

Abstract: Introduction: In 2020, aiming to contain the progression of the Coronavirus pandemic, social distancing was determined by reducing interactions between people. The educational institutions were closed and distance teaching-learning was applied using digital technologies for study continuity. The closing of a community university in Santa Catarina, in the medical course, implied in a disruptive situation regarding the teaching format, since they use active methodologies and these had not been applied digitally up to that moment. From these circumstances, one asks how the faculty perceives and experiences this new reality. Objective: This study aimed to understand the experiences of educators teaching from the first to the fourth year of medical school using active methodologies during the remote education activities at the emergence of the Coronavirus pandemic aiming at understanding the impacts on learning. Method: This is a field research with an exploratory objective and a quantitative-qualitative approach. This study has been analyzed by the Research Ethics Committee. The participants were contacted by electronics means and were invited to answer a two-step questionnaire using the Google Forms platform, containing objective and descriptive questions regarding their experience with remote teaching. Data analysis was performed by statistics, by thematic content analysis and by correlation analysis, and the findings were compared using the theoretical reference. Result: Twenty-nine teachers answered the survey. Most of them felt, at least, partially prepared to work in the remote education and guidance and requests for help were not related to the preparation. Facilities and weaknesses related to the technology were observed. Computers, cell phones and Google Meet were the recourses most often used. Adaptations for the materials used in face-to-face classes were necessary, but in some cases, they were not satisfactory. The pedagogical activities were accomplished within the proposed ones, but two-thirds of the teachers believed there were losses related to study quality and half of them adjusted their behavior to virtual class mediation. Conclusion: The transition to the digital teaching format constituted a challenge for the teachers. The learning process was compromised; however, benefits and potentials were observed. A change is occurring in society and digital teaching is being solidified and training is essential to support this process in active methodologies.

Resumo: Introdução: Em 2020, a fim de conter a progressão da pandemia do coronavírus, determinou-se o distanciamento social por redução da interação entre as pessoas. As instituições de ensino foram fechadas, e adotou-se o ensino-aprendizagem a distância aplicado por tecnologias digitais para a continuidade do estudo. O fechamento de uma universidade comunitária em Santa Catarina, no curso de Medicina, implicou uma situação disruptiva quanto ao formato de ensino, visto que se utilizam metodologias ativas que não haviam sido aplicadas digitalmente até o momento. Dessa circunstância, pergunta-se como o corpo docente percebe e vivencia essa nova realidade. Objetivo: Pretendeu-se conhecer a experiência de professores do primeiro ao quarto ano de graduação médica com metodologias ativas durante as atividades do ensino remoto no advento da pandemia do coronavírus para entender as repercussões na aprendizagem. Método: Trata-se de uma pesquisa de campo, com objetivo exploratório e abordagem quanti-qualitativa. O trabalho passou por apreciação do Comitê de Ética em Pesquisa. Os participantes foram contatados eletronicamente para responder, na plataforma Google Forms, a um questionário dividido em duas etapas com perguntas objetivas e descritivas relativas à vivência deles no ensino remoto. A exploração de dados ocorreu por estatísticas, análise temática de conteúdo e análise de correlação, confrontando-se os resultados com o referencial teórico. Resultado: Responderam à pesquisa 29 professores. A maioria deles se sentiu ao menos parcialmente preparada para atuar no ensino remoto, e orientações e busca por auxílio não se correlacionaram com o preparo. Facilidades e fragilidades relacionadas à tecnologia foram observadas. Computador, celular e Google Meet foram os recursos mais utilizados. Materiais do presencial necessitaram de adaptações, não sendo satisfatórias em alguns casos. As atividades pedagógicas foram cumpridas dentro do proposto, entretanto, para dois terços dos docentes, houve prejuízo na qualidade do ensino, e metade deles mudou de conduta para mediação de aulas virtuais. Conclusão: A passagem para o ensino digital foi um desafio para professores. A aprendizagem foi comprometida, porém observaram-se benefícios e potencialidades. Como há um processo de mudança na sociedade com o propósito de consolidar a educação digital, são essenciais as devidas capacitações para apoiar esse processo em metodologias ativas.

ABSTRACT Research from the last 20 years has provided important insights into the molecular pathogenesis of craniopharyngiomas (CPs). Besides the well-known clinical and histological differences between the subtypes of CPs, adamantinomatous (ACP) and papillary (PCP) craniopharyngiomas, other molecular differences have been identified, further elucidating pathways related to the origin and development of such tumors. The present minireview assesses current knowledge on embryogenesis and the genetic, epigenetic, transcriptomic, and signaling pathways involved in the ACP and PCP subtypes, revealing the similarities and differences in their profiles. ACP and PCP subtypes can be identified by the presence of mutations in CTNNB1 and BRAF genes, with prevalence around 60% and 90%, respectively. Therefore, β-catenin accumulates in the nucleus-cytoplasm of cell clusters in ACPs and, in PCPs, cell immunostaining with specific antibody against the V600E-mutated protein can be seen. Distinct patterns of DNA methylation further differentiate ACPs and PCPs. In addition, research on genetic and epigenetic changes and tumor microenvironment specificities have further clarified the development and progression of the disease. No relevant transcriptional differences in ACPs have emerged between children and adults. In conclusion, ACPs and PCPs present diverse genetic signatures and each subtype is associated with specific signaling pathways. A better understanding of the pathways related to the growth of such tumors is paramount for the development of novel targeted therapeutic agents.
