Abstract Objective To evaluate the validity of the triage system CLARIPED in a pediatric population in the city of São Paulo, Brazil. Methods Prospective, observational study in a secondary-level pediatric emergency service from Sep-2018 to Ago-2019. A convenience sample of all patients aged 0-18 years triaged by the computerized CLARIPED system was selected. Associations between urgency levels and patient outcomes were analyzed to assess construct validity. Sensitivity, specificity, and positive and negative predictive values (PPV and NPV) to identify the most urgent patients were estimated, as well as under-triage and over-triage rates. Results The distribution of 24,338 visits was: RED 0.02%, ORANGE 0.9%, YELLOW 23.5%, GREEN 47.9%, and BLUE 27.7% (highest to the lowest level of urgency). The frequency of the following outcomes increased with increasing urgency: hospital admission (0.0%, 0.02%, 0.1%, 7.1% and 20%); stay in ED observation room (1.9%, 2,4%, 4.8%, 24.1%, 60%); use of ≥ 2 diagnostic/therapeutic resources (2.3%, 3.0%, 5.9%, 28.8%, 40%); ED length of stay (12, 12, 15, 99.5, 362 min). The most urgent patients (RED, ORANGE, and YELLOW) exhibited higher chances of using ≥ 2 resources (OR 2.55; 95%CI: 2.23-2.92) or of being hospitalized (OR 23.9; 95%CI: 7.17-79.62), compared to the least urgent (GREEN and BLUE). The sensitivity to identify urgency was 0.88 (95%CI: 0.70-0.98); specificity, 0.76 (95%CI: 0.75-0.76); NPV, 0.99 (95%CI: 0.99-1.00); overtriage rate, 23.0%, and undertriage, 11.5%. Conclusion This study corroborates the validity and safety of CLARIPED, demonstrating significant correlations with clinical outcomes, good sensitivity, and low undertriage rate in a secondary-level Brazilian pediatric emergency service.

RESUMO O carcinoma hepatocelular (CHC) é uma das principais causas de mortalidade relacionada a câncer no Brasil e no mundo. A Sociedade Brasileira de Hepatologia (SBH) publicou em 2020 a atualização das recomendações da SBH para o diagnóstico e tratamento do CHC. Desde então, novas evidências científicas sobre o tratamento sistêmico do CHC foram relatadas na literatura médica, incluindo novos medicamentos aprovados que não estavam disponíveis na época do último consenso, levando a diretoria da SBH a promover uma reunião monotemática on-line para discutir e rever as recomendações sobre o tratamento sistêmico do CHC. Um grupo de experts foi convidado para realizar uma revisão sistemática da literatura e apresentar uma atualização, baseada em evidências científicas, sobre cada tópico relacionado ao tratamento sistêmico e a apresentar os dados e recomendações resumidas durante a reunião. Todos os painelistas se reuniram para discutir os tópicos e elaborar as recomendações atualizadas. O presente documento é a versão final do manuscrito revisado, contendo as recomendações da SBH, e seu objetivo é auxiliar os profissionais de saúde, formuladores de políticas e planejadores no Brasil e na América Latina na tomada de decisões sobre o tratamento sistêmico de pacientes com CHC.

ABSTRACT Hepatocellular carcinoma (HCC) is the third most common cause of cancer-related mortality worldwide. The Brazilian Society of Hepatology (SBH) published in 2020 the updated recommendations for the diagnosis and treatment of HCC. Since then, new data have emerged in the literature, including new drugs approved for the systemic treatment of HCC that were not available at the time. The SBH board conducted an online single-topic meeting to discuss and review the recommendations on the systemic treatment of HCC. The invited experts were asked to conduct a systematic review of the literature on each topic related to systemic treatment and to present the summary data and recommendations during the meeting. All panelists gathered together for discussion of the topics and elaboration of the updated recommendations. The present document is the final version of the reviewed manuscript containing the recommendations of SBH and its aim is to assist healthcare professionals, policy-makers, and planners in Brazil and Latin America with systemic treatment decision-making of patients with HCC.

Resumo As características anatômicas foliares são amplamente utilizadas para melhor compreender a taxonomia entre as angiospermas. No entanto, tais informação são escassas para a família Myrtaceae. Com o objetivo de preencher esta lacuna de conhecimento, estudamos a anatomia foliar de dez espécies do gênero Psidium: P. cattleyanum, P. cauliflorum, P. corynanthum, P. guajava, P. guineense, P. macahense, P. myrtoides, P. oligospermum, P. ovale e P. sartorianum. A epiderme unisseriada, os estômatos paracíticos, as cavidades secretoras e a hipoderme adaxial são comuns entre as espécies estudadas e são características típicas de Myrtaceae. A presença de três ou mais camadas de parênquima paliçádico e a ausência de esclerênquima são caracteres diagnósticos de P. guajava. A epiderme abaxial de Psidium cattleyanum e P. macahense possuem paredes curvas. Psidium corynanthum e P. macahense são as únicas espécies com paredes anticlinais sinuosas em ambos os lados da epiderme, sendo que todas as outras espécies têm paredes retas ou curvas. Os feixes vasculares bicolaterais abertos estão presentes em todas as espécies estudadas, exceto em P. guineense. Com exceção de P. cauliflorum, todas as espécies estudadas possuem drusas. A ausência de colênquima na face adaxial é exclusiva de P. ovale. A anatomia foliar de P. macahense, P. corynanthum, P. oligospermum e P. ovale é descrita pela primeira vez neste trabalho. angiospermas entanto Myrtaceae conhecimento P cauliflorum guajava guineense myrtoides sartorianum unisseriada paracíticos curvas drusas trabalho

Abstract Leaf anatomical features are widely used to better understand angiosperm taxonomy. However, such information is scarce for the family Myrtaceae. Aiming to fill this knowledge gap, we studied anatomical and micromorphological leaf characters of ten species of Psidium: P. cattleyanum, P. cauliflorum, P. corynanthum, P. guajava, P. guineense, P. macahense, P. myrtoides, P. oligospermum, P. ovale and P. sartorianum. Uniseriate epidermis, paracytic stomata, secretory cavities, and adaxial hypodermis are common among the studied species and are typical characteristics of Myrtaceae. The presence of three or more layers of palisade parenchyma and the absence of sclerenchyma are diagnostic characters of P. guajava. The abaxial epidermis of Psidium cattleyanum and P. macahense possess curved walls. Psidium corynanthum and P. macahense are the only species with sinuous anticlinal walls on both sides of the epidermis, with all other species having straight or curved walls. Open bicollateral vascular bundles are present in all the studied species except P. guineense. With the exception of P. cauliflorum, all the studied species possess druses. The absence of collenchyma in the adaxial face is exclusive to P. ovale. The leaf anatomy of P. macahense, P. corynanthum, P. oligospermum and P. ovale are described for the first time here. taxonomy However Myrtaceae gap P cauliflorum guajava guineense myrtoides sartorianum stomata cavities druses here

Abstract: Malnutrition affects billions of individuals worldwide and represents a global health challenge. This study aimed to determine the prevalence of malnutrition (undernutrition or overweight) among mother-child dyads in children under 5 years old in Brazil in 2019 and to estimate changes in this prevalence from 2006 to 2019. Individual-level data from the Brazilian National Survey on Child Nutrition (ENANI-2019) and the Brazilian National Survey of Demography and Health of Women and Children carried out in 2006 (PNDS 2006) were analyzed. Malnutrition outcomes in mother-child dyads included overweight mother and child, undernourished mother and child, and the double burden of malnutrition, i.e., overweight mother and child having any form of undernourishment (stunting, wasting, or underweight). Prevalence and 95% confidence intervals (95%CI) were estimated. Most women (58.2%) and 9.7% of the children were overweight, 6.9% were stunted, and 3.1% of mothers and 2.9% of the children were underweight. The prevalence of overweight in the mother-child dyad was 7.8% and was statistically higher in Southern Brazil (9.7%; 95%CI: 7.5; 11.9) than in the Central-West (5.4%; 95%CI: 4.3; 6.6). The prevalence of overweight mother and stunted child was 3.5%, with statistically significant difference between the extremes of the mother’s education [0-7 vs. ≥ 12 years, 4.8% (95%CI: 3.2; 6.5) and 2.1%, (95%CI: 1.2; 3.0), respectively]. Overweight in the dyad increased from 5.2% to 7.8%, and the double burden of malnutrition increased from 2.7% to 5.2% since 2006. Malnutrition in Brazilian mother-child dyads seems to be a growing problem, and dyads with lower formal education, higher maternal age, and from the South Region of Brazil were more vulnerable.

Resumo: A má nutrição afeta bilhões de indivíduos em todo o mundo e representa um desafio de saúde global. Este estudo teve como objetivo determinar a prevalência de má nutrição (desnutrição ou excesso de peso) entre díades mãe-filho em crianças menores de cinco anos no Brasil em 2019 e estimar as mudanças nessa prevalência de 2006 a 2019. Foram analisados dados individuais do Estudo Nacional de Alimentação e Nutrição Infantil (ENANI-2019) e da Pesquisa Nacional de Demografia e Saúde da Criança e da Mulher realizada em 2006 (PNDS 2006). Os desfechos de má nutrição incluíram mãe e filho com excesso de peso, mãe e filho desnutridos e a dupla carga de má nutrição, ou seja, mãe com excesso de peso e filho com qualquer forma de desnutrição (défict de crescimento, magreza ou baixo peso). Foram estimadas a prevalência e os intervalos de 95% de confiança (IC95%). A maioria das mulheres (58,2%) e 9,7% das crianças estavam acima do peso, 6,9% apresentaram déficit de crescimento e 3,1% das mães e 2,9% das crianças estavam abaixo do peso. A prevalência de excesso de peso na díade mãe-filho foi de 7,8% e foi estatisticamente maior no Sul do Brasil (9,7%; IC95%: 7,5; 11,9) do que no Centro-oeste (5,4%; IC95%: 4,3; 6,6). A prevalência de mãe com sobrepeso e filho com déficit de crescimento foi de 3,5%, com uma diferença estatisticamente significante entre os extremos de escolaridade materna [(0-7 vs. ≥ 12 anos de estudo), 4,8% (IC95%: 3,2; 6,5) and 2,1% (IC95%: 1,2; 3,0), respectivamente]. O excesso de peso na díade aumentou de 5,2% para 7,8% e a dupla carga de má nutrição aumentou de 2,7% para 5,2% desde 2006. A má nutrição nas díades mãe-filho brasileiras parece ser um problema crescente, sendo as mais vulneráveis aquelas com menor escolaridade e maior idade materna e residentes na Região Sul do Brasil.

Resumen: La malnutrición afecta a muchas personas en todo el mundo y representa un desafío para la salud mundial. Este estudio tuvo como objetivo determinar la prevalencia de malnutrición (desnutrición o sobrepeso) entre díadas madre-hijo en niños menores de cinco años en Brasil en 2019 y estimar cambios en esta prevalencia de 2006 a 2019. Se analizaron datos individuales del Estudio Nacional de Alimentación y Nutrición Infantil (ENANI-2019) y de la Encuesta Nacional de Demografía y Salud del Niño y de la Mujer de 2006 (PNDS 2006). Los resultados de la malnutrición incluyeron a madre e hijo con sobrepeso, madre e hijo desnutridos y la doble carga de mala nutrición, es decir, madre con sobrepeso e hijo con cualquier forma de desnutrición (retardo en el crecimiento, emaciación o bajo peso). Se calcularon prevalencias y los intervalos de 95% de confianza (IC95%). La mayoría de las mujeres (58,2%) y el 9,7% de los niños tenían sobrepeso, el 6,9% de los niños presentaban retraso en el crecimiento, y el 3,1% de las madres y el 2,9% de los niños, bajo peso. La prevalencia de sobrepeso en la díada madre-hijo fue del 7,8%, estadísticamente mayor en el Sur de Brasil (9,7%; IC95%: 7,5; 11,9) que en el Centro-Oeste (5,4%; IC95%: 4,3; 6,6). La prevalencia de madres con sobrepeso y de niños con retraso del crecimiento fue del 3,5%, con una diferencia estadísticamente significativa entre los extremos de nivel educativo de la madre [(0-7 vs. ≥ 12 años de nivel educativo), 4,8% (IC95%: 3,2; 6,5) y 2,1% (IC95%: 1,2; 3,0), respectivamente]. El sobrepeso en la díada tuvo un aumento del 5,2% al 7,8%, y la doble carga de mala nutrición aumentó del 2,7% al 5,2% desde 2006. La malnutrición en la díada madre-hijo brasileña resulta ser un problema creciente, siendo las más vulnerables aquellas con menor escolaridad y mayor edad materna y residentes en la Región Sur de Brasil.

Abstract Objective: To evaluate the validity of the computerized version of the pediatric triage system CLARIPED. Methods: Prospective, observational study in a tertiary emergency department (ED) from Jan-2018 to Jan-2019. A convenience sample of patients aged 0-18 years who had computerized triage and outcome variables registered. Construct validity was assessed through the association between urgency levels and patient outcomes. Sensitivity, specificity, positive and negative predictive values (PPVand NPV), undertriage, and overtriage rates were assessed. Results: 19,122 of 38,321 visits were analyzed. The urgency levels were: RED (emergency) 0.02%, ORANGE (high urgency) 3.21%, YELLOW (urgency) 35.69%, GREEN (low urgency) 58.46%, and BLUE (no urgency) 2.62%. The following outcomes increased according to the increase in the level of urgency: hospital admission (0.4%, 0.6%, 3.1%, 11.9% and 25%), stay in the ED observation room (2.8%, 4.7%, 15.9%, 40.4%, 50%), ≥ 2 diagnostic or therapeutic resources (7.8%, 16.5%, 33.7%, 60.6%, 75%), and ED length of stay in minutes (18, 24, 67,120, 260). The odds of using ≥ 2 resources or being hospitalized were significantly greater in the most urgent patients (Red, Orange, and Yellow) compared to the least urgent (Green and Blue): OR 7.88 (95%CI: 5.35-11.6) and OR 2.85 (95%CI: 2.63-3.09), respectively. The sensitivity to identify urgency was 0.82 (95%CI: 0.77-0.85); specificity, 0.62 (95%CI: 0.61-0.6; NPV, 0.99 (95%CI: 0.99-1.00); overtriage rate, 4.28% and undertriage, 18.41%. Conclusion: The computerized version of CLARIPED is a valid and safe pediatric triage system, with a significant correlation with clinical outcomes, good sensitivity, and low undertriage rate.

Abstract Objectives To study the impact of the implementation of the Pediatric Surviving Sepsis Campaign protocol on early recognition of sepsis, 1 -h treatment bundle and mortality. Methods Retrospective, single-center study, before and after the implementation of the sepsis protocol. Outcomes: sepsis recognition, compliance with the 1 -h bundle (fluid resuscitation, blood culture, antibiotics), time interval to fluid resuscitation and antibiotics administration, and mortality. Patients with febrile neutropenia were excluded. The comparisons between the periods were performed using non-parametric tests and odds ratios or relative risk were calculated. Results We studied 84 patients before and 103 after the protocol implementation. There was an increase in sepsis recognition (OR 21.5 [95% CI: 10.1-45.7]), in the compliance with the 1 -h bundle as a whole (62% x 0%), and with its three components: fluid resuscitation (OR 31.1 [95% CI: 3.9−247.2]), blood culture (OR 15.9 [95% CI: 3.9−65.2]), and antibiotics (OR 35.6 [95% CI: 8.9−143.2]). Significant reduction between sepsis recognition to fluid resuscitation (152min × 12min, p < 0.001) and to antibiotics administration (137min × 30min) also occurred. The risk of death before protocol implementation was four times greater (RR 4.1 [95% CI: 1.2-14.4]), and the absolute death risk reduction was 9%. Conclusion Even if we considered the low precision of some estimates, the lower limits of the Confidence Intervals show that the implementation of the Pediatric Surviving Sepsis Campaign guidelines alongside a qualitive assurance initiative has led to improvements in sepsis recognition, compliance with the 1 -h treatment bundle, reduction in the time interval to fluid resuscitation and antibiotics, and reduction in sepsis mortality.

ABSTRACT BACKGROUND: Cardiovascular risk factors are frequently associated with lowered cognitive performance among elderly people, but rarely among middle-aged adults. OBJECTIVES: To investigate associations between cardiovascular risk factors (age, physical inactivity, smoking, alcohol use, hypertension and diabetes) and lower cognitive performance among middle-aged (45-64 years) Brazilian adults. DESIGN AND SETTING: Cross-sectional study nested within the Pró-Saúde cohort. From 2,876 baseline study participants (1999), we randomly selected 488 participants and gave them validated and standardized cognitive tests (2012). METHODS: We used multiple linear and logistic regression analyses to detect associations of cardiovascular risk factors with crude scores in cognitive tests on memory (word test) and executive function (verbal fluency tests), and with overall cognitive performance scores, respectively. RESULTS: All cognitive test scores presented statistically significant inverse associations with age and direct associations with education. There was no association between lower cognitive performance and smoking or alcohol use. In both 1999 and 2012, after adjusting for sex, age and schooling, being physically active was inversely associated with lower performance regarding late memory. For individuals with diabetes in 1999, there was an association with lower performance regarding executive function, while there was a borderline association for those reporting it only in 2012. Having a diagnosis of hypertension since 1999 was associated with lower performance regarding both memory and executive functions, while reporting hypertension in 2012 was associated with lower performance regarding executive function. CONCLUSIONS: Aging, low schooling and cardiovascular risk factors may represent life course disadvantages associated with cognitive decline even among middle-aged Brazilian adults.

Resumen Antecedentes: El tumor testicular es el tumor sólido más frecuente en hombres entre 20 y 34 años. Los tumores testiculares pueden dividirse histológicamente en células germinales que se presentan en 90-95% y no germinales en alrededor del 5%. Los marcadores tumorales son cruciales en el diagnóstico, clasificación, pronóstico y vigilancia posterior al tratamiento de los tumores testiculares. Objetivo: Conocer la prevalencia puntual de cáncer de testículo en nuestro servicio. Determinar las características clínico-patológicas del cáncer de testículo. Correlacionar los niveles de marcadores tumorales con la estirpe histológica y el estadio clínico del cáncer testicular Metodología: Es un estudio transversal en el que se analizó el total de expedientes de pacientes atendidos en el servicio Urología con diagnóstico de cáncer de testículo, durante el período entre el 1° de enero de 2014 al 31° de diciembre de 2018. Resultados: Se incluyeron 99 pacientes, la media de edad fue de 29±8.5 años. Los tumores que con mayor frecuencia se registraron fueron: tumor de células germinales en el 99%: germinal mixto 50 (50.51%), seguido del seminoma con 42 (42.42%), teratoma 5 (5.05%). La combinación TNM mas comúnmente encontrada fue T1 N0 M0. El estadio clínico mas frecuente fue estadio I, seguido del II y finalmente el III. La alfafetoproteína es el único marcador tumoral que se asocia a extirpe histológica y podría estar asociado a enfermedad diseminada. Limitaciones: Las limitaciones de nuestro estudio es un tamaño de muestra pequeño con una incidencia de algunas variedades de tumores también muy baja. Originalidad: El valor de nuestro estudio es que aporta información sobre la materia en población latinoamericana que es escasamente reportada. Conclusiones: La estirpe histológica que se encontró mayor frecuencia fueron los tumores germinales mixtos y la clasificación TNM más comúnmente encontrada en nuestros pacientes fue T1a, N0, M0 y estadio clínico I. La AFP es el único marcador predictor de la estirpe histológica y de una posible enfermedad diseminada.

Abstract Background: Testicular tumor is the most frequent solid tumor in men between 20 and 34 years of age. Testicular tumors can be histologically divided into germ cell tumors, which present in 90-95% of cases, and non-germ cell tumors, which present in around 5%. Tumor markers are crucial for the diagnosis, classification, and prognosis of testicular tumors, as well as for surveillance after treatment. Objective: To know the actual prevalence of testicular cancer at our service, determine the clinical and pathologic characteristics of testicular cancer, and correlate tumor marker levels with histologic pattern and clinical stage of the disease. Methodology: A cross-sectional study analyzed the case records of patients with testicular cancer seen at the urology service, within the time frame of January 1, 2014 and December 31, 2018. Results: Ninety-nine patients with a mean age of 29±8.5 years were included. The most frequent tumors were germ cell tumors, reported in 99% of cases: 50 were mixed germ cell tumors (50.51%), 42 were seminoma (42.42%), and 5 were teratoma (5.05%). The most common TNM combination was T1 N0 M0. The most frequent clinical stage was stage I, followed by stage II, and then stage III. Alpha-fetoprotein was the only tumor marker that was associated with histologic pattern and possible disseminated disease. Limitations: Small sample size and a low incidence of some of the types of tumor were study limitations. Originality: Our analysis provides information on testicular cancer in a Latin American population, an infrequently studied cohort. Conclusions: The most frequent histologic pattern in our patients was mixed germ cell tumor and the most common TNM classification was T1a, N0, M0 and clinical stage I. Alpha-fetoprotein was the only predictive marker for histologic pattern and possible disseminated disease.

Resumo Objetivo: Descrever as características clínicas de crianças e adolescentes internados em unidade de terapia intensiva com COVID-19 confirmada. Método: Estudo prospectivo, multicêntrico, observacional, em 19 unidades de terapia intensiva pediátrica. Foram incluídos pacientes entre um mês e 19 anos, admitidos consecutivamente (março a maio de 2020). As características demográficas, clínico-epidemiológicas, o tratamento e os resultados foram coletados. Os subgrupos foram comparados de acordo com as comorbidades, idade < 1 ano e necessidade de ventilação mecânica invasiva. Um modelo de regressão logística multivariável foi utilizado para preditores de gravidade. Resultados: Setenta e nove pacientes foram incluídos (10 com síndrome inflamatória multi-ssistêmica). Mediana de idade, quatro anos; 54% eram do sexo masculino (síndrome inflamatória multissistêmica, 80%); 41% tinham comorbidades (síndrome inflamatória multissistêmica, 20%). Febre (76%), tosse (51%) e taquipneia (50%) foram comuns nos dois grupos. Sintomas graves egastrointestinais e marcadores inflamatórios mais elevados foram mais frequentes na presença de síndrome inflamatória multissistêmica. Infiltrados intersticiais pulmonares foram comuns em ambos os grupos, mas o derrame pleural foi mais prevalente no grupo com síndrome inflamatória multissistêmica (43% vs. 14%). A ventilação mecânica invasiva foi utilizada em 18% (mediana 7,5 dias); antibióticos, oseltamivir e corticosteroides foram utilizados em 76%, 43% e 23%, respectivamente, mas não a hidroxicloroquina. A mediana do tempo de permanência na unidade de terapia intensiva pediátrica foi de 5 dias; duas mortes ocorreram (3%) no grupo não- síndrome inflamatória multissistêmica. Os pacientes com comorbidades eram mais velhos, e as comorbidades foram independentemente associadas à necessidade de ventilação mecânica invasiva(OR 5,5; IC95%, 1,43-21,12; P 0,01). Conclusões: Nas unidades de terapia intensiva pediátrica brasileiras, a COVID-19 apresentou baixa mortalidade, a idade inferior a um ano não foi associada a um pior prognóstico, os pacientes com síndrome inflamatória multissistêmica apresentaram sintomas mais graves, biomarcadores inflamatórios mais elevados e uma grande predominância no sexo masculino, mas apenas a presença de comorbidades e doenças crônicas foi um preditor independente de gravidade.

Abstract Objective: To describe the clinical characteristics of children and adolescents admitted to intensive care with confirmed COVID-19. Method: Prospective, multicenter, observational study, in 19 pediatric intensive care units. Patients aged 1 month to 19 years admitted consecutively (March-May 2020) were included. Demographic, clinical-epidemiological features, treatment, and outcomes were collected. Subgroups were compared according to comorbidities, age < 1 year, and need for invasive mechanical ventilation. A multivariable logistic regression model was used for predictors of severity. Results: Seventy-nine patients were included (ten with multisystemic inflammatory syndrome). Median age 4 years; 54% male (multisystemic inflammatory syndrome, 80%); 41% had comorbidities (multisystemic inflammatory syndrome, 20%). Fever (76%), cough (51%), and tachypnea (50%) were common in both groups. Severe symptoms, gastrointestinal symptoms, and higher inflammatory markers were more frequent in multisystemic inflammatory syndrome. Interstitial lung infiltrates were common in both groups, but pleural effusion was more prevalent in the multisystemic inflammatory syndrome group (43% vs. 14%). Invasive mechanical ventilation was used in 18% (median 7.5 days); antibiotics, oseltamivir, and corticosteroids were used in 76%, 43%, and 23%, respectively, but not hydroxychloroquine. The median pediatric intensive care unit length-of-stay was five days; there were two deaths (3%) in the non- multisystemic inflammatory syndrome group. Patients with comorbidities were older and comorbidities were independently associated with the need for invasive mechanical ventilation (OR 5.5; 95% CI, 1.43-21.12; p = 0.01). Conclusions: In Brazilian pediatric intensive care units, COVID-19 had low mortality, age less than 1 year was not associated with a worse prognosis, and patients with multisystemic inflammatory syndrome had more severe symptoms, higher inflammatory biomarkers, and a greater predominance of males, but only comorbidities and chronic diseases were independent predictors of severity.

RESUMO Objetivo: Avaliar a validade e a confiabilidade de um sistema de classificação de risco para emergências pediátricas (CLARIPED) desenvolvido no Brasil. Métodos: Fase de validade: estudo observacional prospectivo em crianças de 0 a 15anos atendidas consecutivamente no serviço de emergência pediátrica (SEP) de um hospital terciário entre 2 e 18de julho de 2013. Avaliou-se a associação dos níveis de urgência com desfechos clínicos (utilização de recursos, taxa de admissão no SEP, taxa de hospitalização e tempo de permanência no SEP); e comparou-se o desempenho do CLARIPED com um padrão de referência. Fase de confiabilidade interobservadores: uma amostra de conveniência de pacientes atendidos entre abril e julho de 2013 foi submetida a duas classificações de risco consecutivas e independentes, e estimou-se o Kappa ponderado quadrático. Resultados: Em 1.416 atendimentos realizados na fase de validade, a distribuição de níveis de urgência foi: 0,0% vermelho/emergência; 5,9% laranja/muito urgente; 40,5% amarelo/urgente; 50,6% verde/pouco urgente; e 3,0% azul/sem urgência. Ospercentuais de pacientes que usaram dois ou mais recursos diminuíram do nível laranja para o amarelo, verde e azul (81, 49, 22 e 2%, respectivamente, p<0,0001), assim como a taxa de admissão no SEP, o tempo de permanência no SEP e a taxa de admissão hospitalar. Asensibilidade para discriminar pacientes muito urgentes foi de 0,89 (intervalo de confiança de 95%- IC95% 0,78-0,95), e a taxa de subtriagem foi de 7,4%. Aconfiabilidade interobservadores em 191 pacientes classificados por duas enfermeiras foi substancial (kw2=0,75; IC95% 0,74-0,79). Conclusões: O sistema CLARIPED mostrou boa validade e substancial confiabilidade para classificação de risco em um serviço de emergência pediátrica.

ABSTRACT Objective: To assess the validity and reliability of a triage system for pediatric emergency care (CLARIPED) developed in Brazil. Methods: Validity phase: prospective observational study with children aged 0 to 15 years who consecutively visited the pediatric emergency department (ED) of a tertiary hospital from July 2 to 18, 2013. We evaluated the association of urgency levels with clinical outcomes (resource utilization, ED admission rate, hospitalization rate, and ED length of stay); and compared the CLARIPED performance to a reference standard. Inter-rater reliability phase: a convenience sample of patients who visited the pediatric ED between April and July 2013 was consecutively and independently double triaged by two nurses, and the quadratic weighted kappa was estimated. Results: In the validity phase, the distribution of urgency levels in 1,416 visits was the following: 0.0% red (emergency); 5.9% orange (high urgency); 40.5% yellow (urgency); 50.6% green (low urgency); and 3.0% blue (no urgency). The percentage of patients who used two or more resources decreased from the orange level to the yellow, green, and blue levels (81%, 49%, 22%, and 2%, respectively, p<0.0001), as did the ED admission rate, ED length of stay, and hospitalization rate. The sensitivity to identify patients with high urgency level was 0.89 (confidence interval of 95% [95%CI] 0.78-0.95), and the undertriage rate was 7.4%. The inter-rater reliability in 191patients classified by two nurses was substantial (kw2=0.75; 95%CI 0.74-0.79). Conclusions: The CLARIPED system showed good validity and substantial reliability for triage in a pediatric emergency department.

ABSTRACT Objectives: The role of viral co-detection in children with severe acute respiratory infection is not clear. We described the viral detection profile and its association with clinical characteristics in children admitted to the Pediatric Intensive Care Unit (PICU) during the 2009 influenza A(H1N1) pandemic. Method: Longitudinal observational retrospective study, with patients aged 0–18 years, admitted to 11 PICUs in Rio de Janeiro, with suspected H1N1 infection, from June to November, 2009. The results of respiratory samples which were sent to the Laboratory of Fiocruz/RJ and clinical data extracted from specific forms were analyzed. Results: Of 71 samples, 38% tested positive for H1N1 virus. Of the 63 samples tested for other viruses, 58 were positive: influenza H1N1 (43.1% of positive samples), rhinovirus/enterovirus (41.4%), respiratory syncytial vírus (12.1%), human metapneumovirus (12.1%), adenovirus (6.9%), and bocavirus (3.5%). Viral codetection occured in 22.4% of the cases. H1N1-positive patients were of a higher median age, had higher frequency of fever, cough and tachypnea, and decreased leukometry when compared to H1N1-negative patients. There was no difference in relation to severity outcomes (number of organic dysfunctions, use of mechanical ventilation or amines, hospital/PICU length of stay or death). Comparing the groups with mono-detection and co-dection of any virus, no difference was found regarding the association with any clinical variable. Conclusions: Other viruses can be implicated in SARI in children. The role of viral codetection has not yet been completely elucidated.

El objetivo de la investigación fue identificar los factores socioeconómicos y parasitológicos que limitan la producción del cacao en Chiapas, México. Se llevaron a cabo encuestas y visitas a 109 productores de las dos principales regiones productoras. Entre los resultados más importantes se registró que solamente el 14.7 % de los productores cultiva cacao de almendra blanca. La unidad de producción promedio es de 2.6 ha. Los productores tienen una edad promedio de 59 años y el 56 % de ellos no completó su instrucción primaria. Sólo el 19.3 % de las unidades productivas está bajo la responsabilidad de mujeres. El rendimiento promedio es de 118 kg ha-1 y el 60.5 % de los productores vende el cacao a intermediarios. Las plagas que afectan al cultivo y su frecuencia son: Moniliophthora roreri(100 %), Phytophthora capsici(67 %), Fusariumsp. (10.1 %), Colletotrichum gloeosporioides(3.7 %), Ceratocystis cacaofunesta(0.9 %), Atta sp. (33.9 %), Toxoptera aurantii (11 %), ardillas (7.3 %), Xyleborus ferrugineus, Xylosandrus morigerus, Hypothenemus birmanus, Corthylus minutissimus, Taurodermus sharpi, Hypothenemus interstitialis(5.5 %), Vanduzea segmentata(5.5 %), pájaro carpintero (4.6 %), Selenothrips rubrocintus (3.7 %), Clastoptera laenata (3.7 %) y tuzas (3.7 %). Moniliophthora es el principal factor que afecta la supervivencia del cacao y su biodiversidad en Chiapas. Esta enfermedad destruye la producción, hace su control no rentable e induce a los agricultores a abandonar sus huertas.

The main goal of this research was to identify the socioeconomic and parasitological factors that limit cocoa production in Chiapas, Mexico. One hundred and nine cacao-growers were visited and interviewed in the two main cocoa-producing regions. According to results only 14.7 % farmers grow white-almond cacao. The average production unit is 2.6 hectares. Cacao growers are 59 years-old on average and 56 % of them did not finish elementary school. Only 19.3 % of the production units are under woman responsibility. Average yield is 118 kg ha-1 and 60.5 % growers sell cacao to intermediaries. Pests that affect the crop and their occurrence include Moniliophthora roreri(100 %), Phytophthora capsici(67%), Fusariumsp. (10.1 %), Colletotrichum gloeosporioides(3.7 %), Ceratocystis cacaofunesta(0.9 %), Atta sp. (33.9 %), Toxoptera aurantii (11 %), squirrels (7.3 %), Xyleborus ferrugineus, Xylosandrus morigerus, Hypothenemus birmanus, Corthylus minutissimus, Taurodermus sharpi, Hypothenemus interstitialis(5.5 %), Vanduzea segmentata(5.5 %), woodpecker (4.6 %), Selenothrips rubrocintus (3.7 %), Clastoptera laenata (3.7 %) and mole (3.7 %). Moniliophthora is the main factor that affects cacao survival and biodiversity in Chiapas. The disease destroys production, makes control uneconomical and causes growers to abandon their plantations.

As Lentiviroses de Pequenos Ruminantes (LVPR) são enfermidades infecciosas de etiologia viral causadas por retrovírus, caracterizadas por uma doença de degeneração progressiva e lenta. O objetivo deste estudo foi determinar a ocorrência de anticorpos contra o lentivírus no rebanho ovino Santa Inês, de Sergipe. Para analisar o número mínimo de amostras utilizou-se o cálculo de Astudillo, com prevalência esperada (p) de 10%, margem de erro (α) de 20% e grau de confiança de 95% (g = 1,96), obtendo-se o número mínimo de amostras (n) de 861. Foram colhidas 941 amostras de soro ovino oriundas de 54 propriedades e 19 municípios distribuídos nas três mesorregiões do Estado, sendo o número de amostras proporcional ao efetivo ovino do município. O soro foi acondicionado a -20°C até a realização do teste de Imunodifusão em Gel de Ágar (IDGA). Os resultados considerados positivos ou suspeitos na IDGA foram reavaliados através da técnica de Western blotting. Dos animais amostrados, 194 (20,62%) eram machos e 747 (79,38%) eram fêmeas. Quanto à estratificação por idade, 300 ovinos eram jovens (31,88%), entre seis meses e um ano, 308 (32,73%) eram jovens adultos, entre 1 e 3 anos, e 333 (35,39%) tinham idade estimada superior a 3 anos. Os resultados obtidos demonstraram que anticorpos contra o vírus Maedi-Visna (MVV) ocorrem no rebanho ovino do estado de Sergipe em baixa frequência (0,11%). Assim, relata-se a ocorrência da infecção por Maedi-Visna em ovinos no estado de Sergipe e ressalta-se a participação do trânsito de animais na epidemiologia da doença.

Small Ruminant Lentiviruses (SRLV) are infectious diseases of viral etiology caused by retroviruses, characterized for being a slowly progressive degenerative disease. The aim of this study was to determine the occcurrence of antibodies against lentivirus in the flock of Santa Inês sheep in Sergipe, Brazil. A minimum number of samples was analyzed by the Astudillo calculation, with an expected prevalence (p) of 10%, error rate (α) of 20% and confidence level of 95% (g = 1.96) obtaining the minimum number of samples (n) of 861. Finally, 941 serum samples were collected, derived from 54 properties and 19 municipalities distributed in three regions of the State, and the number of collected samples was proportional to the sheep flock of each municipality. The serum was placed at -20°C until the Agar Gel Immunodiffusion test (AGID), and results considered as positive or suspicious in AGID were assessed by the Western blotting technique. Out of sampled animals, 194 (20.62%) were male and 747 (79.38%) were female. From the stratification by age, 300 were young sheep (31.88%), aged between six months and one year old, 308 (32.73%) were young adults, aged between 1 and 3 years old, and 333 (35.39%) were estimated to be older than three years old. Results showed that antibodies against the Maedi-Visna virus in the sheep flock occcurred in the State of Sergipe at low frequency (0.11%). Thus, the occcurrence of Maedi-Visna infection in sheep in the State of Sergipe is reported, and emphasizes the participation of the transit of animals in the epidemiology of the disease.
