ABSTRACT BACKGROUND: Dynapenia is a risk factor of mortality. Therefore, the development of low-cost and easy-to-apply tools is essential to optimize the health surveillance actions of older people. OBJECTIVES: To compare the time spent on habitual physical activity (HPA) and sedentary behavior (SB) among dynapenic and non-dynapenic older adults and ascertain the predictive ability of these behaviors on outcome. DESIGN AND SETTING: A cross-sectional population epidemiological survey was conducted involving 208 older adults. METHODS: HPA and SB were quantified using the International Physical Activity Questionnaire, and dynapenia was identified by handgrip strength (women: 18.37 kgf; men: 26.75 kgf). RESULTS: The prevalence was 24.50%. In both sexes, dynapenic individuals reported a HPA median time of 70.00 minutes/week (min/wk), while non-dynapenic women and men reported HPA median times of 240.00 and 280.00 min/wk, respectively (P < 0.05). For SB among dynapenic individuals, a median of 388.75 min/day was observed in women and 428.57 min/d in men. In contrast, non-dynapenic women and men had 291.42 and 274.28 min/day in SB (P < 0.05), respectively. The best cutoff HPA to discriminate the outcome was 150.00 min/wk in women (sensitivity: 73.30%; specificity: 60.67%) and 140.00 min/wk in men (sensitivity, 71.43%; specificity, 61.54%). The best cutoff SB was 381.43 min/day in women (sensitivity, 53.30%; specificity, 84.80%) and 351.43 min/day in men (sensitivity, 71.43%; specificity, 73.85%). CONCLUSION: Older individuals with dynapenia spent less time on HPA and more time in SB. Furthermore, HPA was found to be a better discriminator of dynapenic individuals, and SB better discriminated non-dynapenic individuals.

ABSTRACT Objective: To evaluate the psychometric properties and reliability of the Brazilian version of the tool Parent Attitudes about Childhood Vaccine (PACV-BR). Methods: The sample included 110 parents of children up to two years old served by Family Health Basic Units. The tool's internal consistency and factor validity were respectively assessed by Cronbach's alpha and exploratory factor analysis (EFA). The test-retest reliability was assessed by the intraclass correlation coefficient (ICC). Results: The EFA results indicated a proper structural adequacy of the PACV-BR (15 items and two factors). The reliability generated Cronbach's alpha values between 0.715 and 0.854 for the items, of 0.918 for the tool as a whole, of 0.877 for factor 1 and of 0.825 for factor 2, in addition to an ICC of 0.984. Conclusions: The PACV-BR showed evidence of construct validity and reliability.

RESUMO Objetivo: Avaliar as propriedades psicométricas e a confiabilidade da versão brasileira do instrumento Parent Attitudes about Childhood Vaccine (PACV-BR). Métodos: A amostra incluiu 110 pais de crianças de até dois anos atendidas em Unidades Básicas de Saúde da Família. A consistência interna e a validade fatorial do instrumento foram avaliadas, respectivamente, pelo alfa de Cronbach e pela análise fatorial exploratória (EFA). A confiabilidade teste-reteste foi avaliada pelo coeficiente de correlação intraclasse (ICC). Resultados: Os resultados da AFE indicaram adequação estrutural do PACV-BR (15 itens e dois fatores). A confiabilidade indicou valores de alfa de Cronbach entre 0,715 e 0,854 para os itens, de 0,918 para o instrumento como um todo, de 0,877 para o fator 1 e de 0,825 para o fator 2, além de ICC de 0,984. Conclusões: O PACV-BR apresentou evidências de validade de construto e confiabilidade.

Abstrac This study assesses the joint influence of capillary absorption and substrate roughness on the adhesive strength of a cementitious matrix on brick substrate. One cementitious rendering and two substrates with different water absorption and roughness were used. The capillary absorption coefficient and the roughness coefficient were determined in 1cm2 test areas to then evaluate the matrix tensile bond strength and correlate it with the properties of the substrates. The results were validated by SEM and AFM analyses. Substrates with higher capillary absorption and lower roughness presented higher tensile bond strength. Micro and nanoscale analyses led us to conclude that, in the substrates used, the higher capillary absorption and the lower roughness generate a denser and less porous paste-substrate interface, suggesting a higher extent of contact between the hydrated paste and the substrate and, consequently, higher adhesive strength.

Resumo Este estudo avalia a influência conjunta da absorção capilar e da rugosidade do substrato na adesão de uma matriz cimentícia em um bloco cerâmico. Foram usados um revestimento cimentício e dois substratos com absorção de água e rugosidade diferentes. O coeficiente de absorção capilar e o coeficiente de rugosidade da superfície foram determinados em áreas de teste de 1 cm 2 , sendo correlacionados com a resistência de aderência. Os resultados foram validados por análises de MEV e MFA. Os substratos com maior absorção capilar e menor rugosidade apresentaram maior resistência à tração. As análises em micro e nanoescala permitem concluir que, nos substratos utilizados, a maior absorção capilar e a menor rugosidade geram uma interface pasta-substrato mais densa e menos porosa, sugerindo uma maior extensão de contato entre a pasta hidratada e o substrato e, consequentemente, maior resistência de aderência.

Resumo Trata-se de um estudo ecológico que analisou a tendência temporal das taxas de incidência de leishmaniose visceral no Brasil mediante regressão temporal segmentada por pontos de inflexão. Observou-se tendência de decréscimo na taxa de incidência dessa patologia no país, com variação variação percentual média anual (average annual percent change - AAPC) de -5 (IC95%: -9,1; -0,6) e redução de 1,69 casos/100 mil habitantes em 2007, para 0,91/100 mil habitantes em 2020. A região Centro-Oeste apresentou a maior redução do AAPC (AAPC: -9,1; IC95%: -13,8; -4,3), seguida da região Sudeste (AAPC: -8,7; -14,6; -2,5). As regiões Norte e Sul apresentaram o maior número de pontos de inflexão (joinpoint) na série temporal. As maiores incidências foram registradas na população masculina, porém com tendência estacionária (AAPC: 2,14; IC95%: -8,3; 0). Na análise por faixa etária, a tendência foi decrescente nos grupos de 0 a 4 anos (AAPC: -7,7; IC95%: -12,6; -2,4), 5 a 9 anos (AAPC: -7,3; IC95%: -13,6; -0,4) e de 10 a 14 anos (AAPC: -5,5; IC95%: -10,3; -0,3). Verificou-se que, apesar de a leishmaniose visceral se tratar de uma doença endêmica no Brasil, houve declínio na sua taxa de incidência no período de 2007 a 2020.

Abstract It is an ecological study that analyzed the time trend of visceral leishmaniasis incidence rates in Brazil using segmented time regression by joinpoints. There was a decreasing incidence rate of this disease in the country with an average annual percent change (AAPC) of -5 (CI95%: -9.1; -0.6) and a reduction of 1.69 cases/100 thousand inhabitants in 2007, and 0.91/100 thousand inhabitants in 2020. The Central-West region showed the highest reduction percent (AAPC: -9.1; CI95%: -13.8; -4.3), followed by the Southeast region (AAPC: -8.7; -14.6; -2.5). The North and South regions showed the largest number of joinpoints in the time series. The highest incidences were recorded in the male population, however, stable (AAPC: 2.14; CI95%: -8.3; 0). In the age group analysis, the trend was decreasing for the groups from 0 to 4 years old (AAPC: -7.7; CI95%: -12.6; -2.4), 5 to 9 years old (AAPC: -7.3; CI95%: -13.6; -0,4) and 10 to 14 years old (AAPC: -5.5; CI95%: -10.3; -0.3). It was found that although Visceral Leishmaniasis is an endemic disease in Brazil, there was a decrease in its incidence rate from 2007 to 2020.

The aim of this study was to verify the effects of verbal interventions performed by the coach on the tactical performance of young soccer players. 24 under-13 players and a coach with more than 10 years of experience participated in this study. Players were submitted to two conditions: experimental (small-sided games with verbal intervention) and control (small-sdeid games without verbal intervention). The players, in both conditions, played small-sided games in the format Goalkeeper+3 vs. 3+Goalkeeper, lasting 4 minutes. Tactical performance was analyzed using the Football Tactical Assessment System (FUT-SAT), considering the 10 fundamental tactical principles. The categorization of verbal interventions performed by the coach was performed through content analysis. The results show that the verbal interventions used (~90% instructive/direct) positively influenced the defensive tactical performance, however, they had a negative impact on the offensive tactical performance. It is concluded that the coach's verbal interventions can be important pedagogical tools to guide the tactical performance of young players. However, the predominance of direct instructions can compromise the offensive tactical performance during small-sided games in young players. Coaches, therefore, should reflect on how and in what ways to communicate with their players, in an attempt to promote a more representative learning environment.

El objetivo de este estudio fue verificar los efectos de las intervenciones verbales realizadas por el entrenador en el desempeño táctico de jóvenes futbolistas. En este estudio participaron 24 jugadores menores de 13 años y un entrenador con más de 10 años de experiencia. Los jugadores fueron sometidos a dos condiciones: experimental (juegos reducidos con intervención verbal) y control (juegos reducidos sin intervención verbal). Los jugadores, en ambas condiciones, jugaron partidos reducidos en el formato Portero+3 vs. 3+Portero, con una duración de 4 minutos. El desempeño táctico se analizó mediante el Sistema de Evaluación Táctica del Fútbol (FUT-SAT), considerando los 10 principios tácticos fundamentales. La categorización de las intervenciones verbales realizadas por el entrenador se realizó a través del análisis de contenido. Los resultados muestran que las intervenciones verbales utilizadas (~90% instructivas/directas) influyeron positivamente en el desempeño táctico defensivo, sin embargo, tuvieron un impacto negativo en el desempeño táctico ofensivo. Se concluye que las intervenciones verbales del entrenador pueden ser importantes herramientas pedagógicas para orientar el desempeño táctico de los jóvenes jugadores. Sin embargo, el predominio de las instrucciones directas puede comprometer el desempeño táctico ofensivo durante juegos reducidos en jugadores jóvenes. Los entrenadores, por lo tanto, deberían reflexionar sobre cómo y de qué manera comunicarse con sus jugadores, en un intento de promover un entorno de aprendizaje más representativo.

O objetivo deste estudo foi verificar os efeitos das intervenções verbais realizadas pelo treinador sobre o desempenho tático de jovens jogadores de futebol. Participaram deste estudo 24 jogadores da categoria sub-13 e um treinador, com mais de 10 anos de experiência. Os jogadores foram submetidos a duas condições: experimental (jogos reduzidos com intervenção verbal) e controle (jogos reduzidos sem intervenção verbal). Os jogadores, em ambas as condições, realizaram jogos reduzidos no formato Goleiro+3 vs. 3+Goleiro, com duração de 4 minutos. O desempenho tático foi analisado por meio do Sistema de Avaliação Tática no Futebol (FUT-SAT), considerando os 10 princípios táticos fundamentais. A categorização das intervenções verbais realizadas pelo treinador foi realizada por meio da análise de conteúdo. Os resultados mostram que as intervenções verbais utilizadas (~90% instrutivos/diretos) influenciaram positivamente no desempenho tático defensivo, porém, exerceram impacto negativo no desempenho tático ofensivo. Conclui-se que intervenções verbais do treinador podem se constituir ferramentas pedagógicas importantes para orientar o desempenho tático de jovens jogadores. Contudo, a predominância de instruções diretas pode comprometer o desempenho tático ofensivo durante jogos reduzidos em jovens jogadores. Os treinadores, portanto, devem refletir sobre como e de que forma se comunicar com seus jogadores, na tentativa de promover um ambiente de aprendizagem mais representativo.

RESUMO Objetivo: Realizar uma revisão narrativa dos principais sistemas de triagem pediátrica nos serviços de emergência. Fontes de dados: Artigos publicados entre 1999 e 2019, obtidos por meio de busca nos bancos de dados Medical Literature Analysis and Retrieval System Online (Medline), Embase e PubMed usando as palavras-chave “pediatric triage”, “pediatric assessment tools” e “emergency department triage”, com ênfase em estudos que avaliaram a validação e a confiabilidade desses sistemas. Síntese dos dados: Foram avaliados 105 artigos sobre sistemas de triagem na emergência pediátrica de 12 países. Os sistemas de triagem foram divididos em dois grupos: estratificados por cores e de alerta. Os sistemas de triagem com estratificação por cores incluídos nesta revisão foram: Canadian Triage and Acuity Scale (CTAS), Manchester Triage System (MTS), Emergency Severity Index (ESI) e Australian Triage Scale (ATS). Os sistemas de alerta incluídos foram: Paediatric Observation Priority Score (POPS), Pediatric Early Warning Score (PEWS) e Pediatric Approach Triangle (PAT). Há evidências que corroboram a validade e a confiabilidade do MTS, PedCTAS, ESI v.4, PEWS, POPS e PAT em serviços de emergência de pediátricos. Conclusões: Os sistemas de triagem são ferramentas fundamentais para o atendimento de pacientes que procuram serviços de emergência. Nem todos os sistemas de triagem foram avaliados para validação e confiabilidade nem se aplicam a todas as regiões do mundo. Para a aplicação de sistemas de triagem no Brasil, devem ser feitos adaptação cultural e treinamento do estafe de saúde local, bem como estudos de validação e confiabilidade em nosso país, dado o seu contexto social e cultural diferente daquele dos países onde essas ferramentas foram desenvolvidas.

ABSTRACT Objective: The aim of this study was to perform a narrative review of the leading pediatric triage systems in emergency departments (EDs). Data source: Articles published between 1999 and 2019 were identified by searching the MEDLINE, EMBASE, and PubMed databases using the keywords “pediatric triage”, “pediatric assessment tools”, and “emergency department triage” with an emphasis on studies that evaluated the validation and reliability of triage systems. Data synthesis: A total of 105 articles on pediatric emergency triage systems in 12 countries were evaluated. Triage systems were divided into two groups: color-stratified triage systems and alert systems. The color-stratified triage systems included in this review were the Canadian Triage and Acuity Scale (CTAS), Manchester Triage System (MTS), Emergency Severity Index (ESI), and Australasian Triage Scale (ATS), and the alert systems included were the Paediatric Observation Priority Score (POPS), Pediatric Early Warning Score (PEWS), and Pediatric Approach Triangle (PAT). Evidence corroborates the validity and reliability of MTS, PaedCTAS, ESI version 4, PEWS, POPS, and PAT in pediatric emergency services. Conclusions: These are fundamental tools for risk classification of patients seeking treatment in EDs. Not all triage systems have been assessed for validity and reliability; nor are they well suited for all regions of the world. Employing triage systems in Brazil requires cultural adaptation and rigorous training of the local health staff, in addition to validation and reliability studies in our country, since the social and cultural context of this country differs from those where these tools were developed.

Resumen: El objetivo de este estudio fue traducir y realizar la adaptación intercultural de Family Health Scale (Escala de Salud Familiar) al portugués brasileño, y analizar la evidencia de la validez psicométrica de esta escala. Los 32 ítems sobre salud familiar pasaron por una adaptación transcultural y, para medir la evidencia de validez de contenido, se utilizó el cálculo del índice de validez de contenido de las características semántica, idiomática, cultural y conceptual de cada ítem, y la escala. Se realizó una prueba previa con 40 familias para identificar la evidencia de validez. En otro momento, el instrumento se aplicó a 354 familias en una ciudad del Nordeste de Brasil. El índice de acuerdo entre los jueces osciló entre 0,84 para los ítems de la escala y 0,98 para la escala total de acuerdo con el coeficiente de Kendall. La evidencia de validez psicométrica es adecuada conforme el alfa de Cronbach. La mayoría de las familias tenían un grado de salud moderado de acuerdo con la aplicación de la escala. Por lo tanto, la Family Health Scale, versión brasileña, presentó equivalencia conceptual, semántica, cultural y operativa con relación a los ítems originales, y propiedades psicométricas satisfactorias para la aplicación en la población brasileña, lo que da fe de la eficacia y seguridad de su uso.

Resumo: Os objetivos deste estudo foram realizar a tradução e adaptação transcultural da Family Health Scale (Escala de Saúde Familiar) para a língua portuguesa brasileira e analisar evidências de validade psicométricas dessa escala. Os 32 itens sobre a saúde familiar foram adaptados transculturalmente. Para a mensuração das evidências de validade do conteúdo, utilizou-se o cálculo do índice de validade de conteúdo das características semântica, idiomática, cultural e conceitual de cada item e da escala. Um pré-teste para identificação de evidência de validade foi realizado com 40 famílias. Em outro momento, a aplicação do instrumento foi executada com 354 famílias, em uma cidade no Nordeste do Brasil. O índice de concordância entre os juízes variou de 0,84, para os itens da escala, a 0,98, para a escala total, conforme o coeficiente de Kendall. As evidências de validade psicométricas mostram-se adequadas, conforme alfa de Cronbach. A maior parte das famílias teve um grau de saúde moderado, conforme aplicação da escala. Assim, a Family Health Scale, versão brasileira, apresentou equivalência conceitual, semântica, cultural e operacional em relação aos itens originais e propriedades psicométricas satisfatórias para a aplicação direcionada à população brasileira, atestando eficácia e segurança de sua utilização.

Abstract: This study aimed to translate and cross-culturally adapt the Family Health Scale into Brazilian Portuguese and analyze evidence of its psychometric validity. The 32 items on family health were cross-culturally adapted, using the content validity index to calculate semantic, idiomatic, cultural, and conceptual characteristics of the scale and its items. A pre-test to identify evidence of validity was applied to 40 families. At another time, the instrument was applied to 354 families in a Brazilian northeastern city. The index of agreement between the raters ranged from 0.84 for the scale items to 0.98 for the total scale, according to Kendall’s coefficient. According to Cronbach’s alpha, evidence of psychometric validity is adequate. Most families had a moderate degree of health, according to the scale. Therefore, the Brazilian version of the Family Health Scale showed conceptual, semantic, cultural, and operational equivalence with the original items, along with satisfactory psychometric properties for use among the Brazilian population with effectiveness and safety.

ABSTRACT Insects are fundamental to biodiversity conservation in almost all ecosystems, and their population decline, and extinction directly result from environmental impacts. These facts are aggravated by the lack of knowledge of insect biodiversity, the so-called biodiversity deficits, especially the Linnean and Wallacean shortfalls. In freshwater ecosystems, biodiversity loss is higher among aquatic insects, and caddisflies comprise one of the most vulnerable orders. In this way, research focusing on describing new caddisfly species and understanding their distribution ranges will increase knowledge of caddisfly biodiversity. In the past 14 years, the team from the Laboratório de Entomologia Aquática “Prof. Dr. Claudio Gilberto Froehlich” (LEAq, Universidade Federal da Bahia, Brazil) and collaborators have been addressing these issues, resulting in 55 described species of caddisflies. Taxa in other insect orders have also received attention and an additional 16 species have been described (eight mayflies, four stoneflies, four neuropteran spongillaflies, and antlions). Here, eight caddisfly species are described and illustrated (Atopsyche froehlichi sp. nov., Austrotinodes zeferina sp. nov., Cernotina kariri sp. nov., Neoathripsodes froehlichi sp. nov., Notalina claudiofroehlichi sp. nov., Oecetis marcus sp. nov., Phylloicus froehlichi sp. nov., and Polycentropus claudioi sp. nov.), five of them in honor of LEAq’s patron. In addition, new distributional data are presented for 10 known species. A checklist of the caddisfly fauna of Bahia state is also presented, with 138 species, around 75% and 30% of them recorded and described by the LEAq team, respectively. Currently, for caddisflies, Bahia is the fifth most species-rich state in Brazil, and the first in the Brazilian Northeast region.

ABSTRACT Podzols are highly sandy soils, in which elements, such as potassium, needed by crops, are easily leached. Studies have indicated that biochar can contribute to increasing cation exchange capacity of the soil, which can improve the retention of bases. This study aimed to evaluate the effect of the poultry litter biochar combined or not with increasing doses of KCl, on leaching and soil base content, on the production of green manure biomass, and on the distribution of K in the soil-water-plant system. A 2 × 3 factorial experiment was conducted in randomized blocks with 6 repetitions: without and with biochar (1% v / v, produced from poultry litter) × without K, with 53.65 and 107.30 mg dm-3 of K (as KCl). The experiment was carried out in four steps: Step 1) Soil incubation with the treatments (for 20 days) followed by chemical analysis of the soil; Step 2) First leaching: the containers (made with PVC with 0.30 m high) received the newly incubated soil in the surface layer and soil without treatment in the subsurface layer. The containers received water until saturation plus 50 % of the total pore volume and the leached water was collected and analyzed; Step 3) Cultivation of green manure (Mucuna aterrima) in the containers of Step 2 and harvest within 40 days (evaluation of biomass and K content); Step 4) after the mucuna harvest, the containers were subjected to second leaching. The leaching solution and the soil from the surface and subsurface layers were collected for chemical analysis. Biochar increased the pH, cationic exchange capacity, P, K, Ca, and Mg levels in the newly incubated soil, in the surface and subsurface layer. The increasing doses of KCl proportionally increased biomass production and K accumulation in green manure, and the biochar increased this response and reduces the need for potassium fertilization by 50 %. With biochar, the accumulation of total K in the soil-plant-water system increases by 125 % and, in the soil-plant system, by 145 %. Biochar changes the K ratio in the soil-plant-water system. With biochar, proportionally, the highest accumulated percentage of K occurred mainly in the soil surface and subsurface layer, and did not result in higher percentages of K in the leached water. Biochar produced from poultry litter can be used as a good alternative to improve the chemical properties of Podzols and reduce nutrient losses.

ABSTRACT Coordinated and harmonic (synchronous) ventricular electrical activation is essential for better left ventricular systolic function. Intraventricular conduction abnormalities, such as left bundle branch block due to artificial cardiac pacing, lead to electromechanical “dyssynchronopathy” with deleterious structural and clinical consequences. The aim of this review was to describe and improve the understanding of all the processes connecting the several mechanisms involved in the development of artificially induced ventricular dyssynchrony by cardiac pacing, most known as pacing-induced cardiomyopathy (PiCM). The chronic effect of abnormal impulse conduction and nonphysiological ectopic activation by artificial cardiac pacing is suspected to affect metabolism and myocardial perfusion, triggering regional differences in the activation/contraction processes that cause electrical and structural remodeling due to damage, inflammation, and fibrosis of the cardiac tissue. The effect of artificial cardiac pacing on ventricular function and structure can be multifactorial, and biological factors underlying PiCM could affect the time and probability of developing the condition. PiCM has not been included in the traditional classification of cardiomyopathies, which can hinder detection. This article reviews the available evidence for pacing-induced cardiovascular disease, the current understanding of its pathophysiology, and reinforces the adverse effects of right ventricular pacing, especially right ventricular pacing burden (commonly measured in percentage) and its repercussion on ventricular contraction (reflected by the impact on left ventricular systolic function). These effects might be the main defining criteria and determining mechanisms of the pathophysiology and the clinical repercussion seen on patients.

ABSTRACT In order to evaluate the microbiological quality of water and oysters from natural banks and oyster farms located on the Island of São Luís, Maranhão (MA), 60 samples were analyzed from September 2020 to February 2021, 30 of water and 30 of oysters (Crassostrea sp.), collected directly from shellfish farmers and owners of oyster farms in the municipalities of the Island of São Luís, MA. For the determination of total coliforms and Escherichia coli in the water samples the Colilert® rapid method was used. For the enumeration of total and thermotolerant coliforms in oysters the Most Probable Number (MPN) method was used and E. coli by biochemical tests (Indol, MV, VP, Citrate). The enumeration of coagulase positive Staphylococcus was performed using Baird Parker medium for isolation and identification, as well as biochemical tests. The geometric mean result of E. coli counts in the water samples ranged from 604.3 to 1,130.8 MPN/100mL, indicating unsatisfactory microbiological quality. As for the oyster samples, 8 (26.7%) out of 30 samples were unfit for consumption, and 4 (13.3%) were contaminated by Salmonella sp. and E. coli, respectively. According to RDC No. 331/19 and IN No. 60 of ANVISA, the results are worrisome for public health and mitigating actions are recommended, such as regular monitoring of the microbiological quality of the water.

Resumo Com o objetivo de avaliar a qualidade microbiológica de águas e ostras de bancos naturais e ostreiculturas localizados na ilha de São Luís (MA), foram analisadas no período de setembro de 2020 a fevereiro de 2021 60 amostras, sendo 30 de água e 30 de ostras (Crassostrea sp.), coletadas diretamente com os marisqueiros e proprietários de cultivos nos municípios da ilha de São Luís. Para a determinação de coliformes totais e Escherichia coli nas amostras de água, foi utilizado o método rápido Colilert®. A contagem de coliformes totais e termotolerantes em ostras foi realizada pelo método do número mais provável (NMP) e de E. coli por testes bioquímicos (Indol, VM, VP, Citrato). A enumeração de Staphylococcus coagulase positiva ocorreu pelo meio Baird Parker para isolamento e identificação, assim como por testes bioquímicos. A média geométrica do resultado da contagem de E. coli nas amostras de água variou entre 604,3 e 1.130,8 NMP/100 mL, indicando qualidade microbiológica insatisfatória. Quanto às amostras de ostras, oito (26,7%) das 30 amostras estavam impróprias para consumo, sendo quatro (13,3%) contaminadas por Salmonella sp. e E. coli, respectivamente. Segundo a Resolução da Diretoria Colegiada nº 331/19 e a Instrução Normativa nº 60 da Agência Nacional de Vigilância Sanitária, os resultados são preocupantes para a saúde pública, e recomendam-se ações mitigadoras, como o monitoramento regular da qualidade microbiológica da água.

ABSTRACT Introduction: The exponential growth of telehealth services during the COVID-19 pandemic led to the implementation of a telemedicine care service in a tertiary university pediatric hospital. It brought the need to develop a training aimed at remote care within the pediatric emergency rotation program. Objective: To describe the implementation of a telemedicine training for pediatric residents and present the preliminary results. Methods: Descriptive prospective study (pre and post), with 40 resident physicians of the first year of pediatrics. Reaction Assessments were applied before and after training, in addition to a resident physician perception questionnaire at the end of the training. Results: There was a significant difference in the resident’s perception of experience and safety after initial training. Most rated the proposal as good or excellent, considered teaching telemedicine relevant and that this experience contributed to their learning on the subject. Conclusion: This study describes an innovative proposal for training in telemedicine. The preliminary results were encouraging, demonstrating the program’s potential in training future pediatricians.

ABSTRACT In the Cerrado, the palm swamps ( veredas ) are characterized by being humid and stable environments that lead to the formation of Histosols ( Organossolos ). and soils with surface horizons of organic constitution, which are fragile and sensitive to anthropic action. This study aimed to evaluate the impact of anthropization (recurrent forest fires and livestock farming) on the chemical, physical and morphological properties of soils in two palm swamps in the Environmental Preservation Area (EPA) of Pandeiros River, Minas Gerais, namely: Água Doce, in preserved condition, and Taboa, in anthropized condition. Four soil profiles were morphologically described, two profiles in each palm swamp, with subsequent chemical and physical analyses, calculations of organic carbon stock and identification of the origin of organic matter. The results were analyzed using descriptive statistics and Pearson’s correlation coefficient. Soil morphological properties were influenced by vegetation cover, drainage and anthropization conditions. As for the physical and chemical properties, adequate values were observed in the preserved palm swamp, including lower bulk density values and higher cation contents. Anthropic actions in the anthropized palm swamp caused degradation of soils, revealed by subsidence, reduction in organic carbon content, increase in bulk density and decrease in fertility. Changes promoted in the soils of the palm swamps compromise ecosystem services, indicating that actions at either local or governmental level should be stimulated for the preservation and conservation of these environments.
