Abstract This study aimed to examine the relative age effect on muscle power in a large sample of Brazilian children and adolescents. The sample consisted of 87,766 girls and boys aged 7-16 years, data collected in repeated cross-sectional surveillance carried out since 1999. The participants were grouped into four age subgroups within each chronological age based on birthdates. Upper and lower limbs muscle power were assessed using the 2-Kg medicine ball throw and horizontal jump tests, respectively. The normative distribution of physical fitness components was used for classification. The results showed a significant association between relative age and normative classification of muscle power. Among boys, there was a sequential increase in the frequency of individuals classified as “very good/excellent” as the relative age increased. A similar trend was observed among girls. The findings provided evidence of a relative age effect on muscle power in Brazilian children and adolescents. These findings have implications for the organization of structured physical activities and sports, as early-born individuals may have an advantage in performance. Further research is needed to explore the underlying mechanisms and potential interventions to mitigate the relative age effect and promote equal opportunities for all youth in physical activities and sports. adolescents 87766 87 766 87,76 716 7 16 7-1 years crosssectional cross sectional 1999 birthdates 2Kg Kg 2 tests respectively very good/excellent goodexcellent good excellent increased sports earlyborn early born performance 8776 8 76 87,7 71 1 7- 199 877 87, 19

Resumo Este estudo teve como objetivo examinar o efeito da idade relativa na potência muscular em crianças e adolescentes brasileiros. A amostra foi composta por 87.766 meninas e meninos com idades entre 7 e 16 anos. Os participantes foram agrupados em quatro subgrupos etários dentro de cada idade cronológica tendo como base as datas de nascimento e da coleta dos dados. A potência muscular dos membros superiores e inferiores foi avaliada por meio dos testes de arremesso de medicine ball de 2 kg, e salto horizontal, respectivamente. A distribuição normativa (fraco; razoável; bom; muito bom; excelente) dos dois testes de potência foi utilizada para a classificação. Os resultados mostraram associação significativa entre os subgrupos etários e a classificação normativa da potência muscular. Entre os meninos, houve aumento na frequência de indivíduos classificados como “muito bom/excelente” à medida que a idade relativa aumentava. Uma tendência semelhante foi observada entre as meninas. Os achados forneceram evidências do efeito de idade relativa na potência muscular de crianças e adolescentes brasileiros. Esses resultados têm implicações práticas na organização de atividades físicas estruturadas e esportes em diferentes contextos, pois indivíduos nascidos mais cedo podem ter vantagem no desempenho em tarefas que exijam potência muscular. Mais pesquisas são necessárias para explorar os mecanismos subjacentes e intervenções que possam mitigar o efeito de idade relativa e promover oportunidades iguais para todas as crianças e adolescentes nas atividades físicas e esportes. brasileiros 87766 87 766 87.76 1 anos dados kg horizontal respectivamente fraco (fraco razoável bom excelente bom/excelente bomexcelente aumentava contextos 8776 8 76 87.7 877 87.

Abstract Vismia japurensis Reichardt is a plant of ecological and chemical importance from which a variety of bioactive substances have been isolated. The current study aimed to establish in vitro cultures of this species as a source of secondary metabolites. Appropriate decontamination treatments and germination tests were performed and, after in vitro culture establishment, the propagated plants were multiplied in a sterile environment to increase the biomass of available experimental material. Seeds showed low contamination and a high germination percentage on Woody Plant Medium (WPM) supplemented with gibberellic acid (both at concentrations of 5 and 10 mg/L). V. japurensis nodal segments rapidly regenerated when first grown in WPM and then transplanted to Murashige and Skoog medium (MS). After 60 days in MS medium, the propagated plants were removed, lyophilized, and extracted with hexane and methanol. The hexane extract was fractionated via open column chromatography, and the substance isolated was purified by high performance liquid chromatography. Structural determination of the isolated substance was carried out using one and two-dimensional nuclear magnetic resonance and mass spectrometry. The isolated substance was identified as 1,8,10-trihydroxy-3,10-dimethyl-9(10H)-anthracenone, which, based on the conducted literature search, is reported for the first time. metabolites establishment material (WPM both 1 mg/L. mgL mg/L . mg L mg/L) V MS.

Abstract Background Postoperative cough may occur after tracheal intubation, but it is indistinct which drug is best at diminishing these events. Additionally, airway reflexes are commonly accompanied by severe hemodynamics responses during emergence. Objectives To evaluate the role of topical airway anesthesia on immediate post-extubation cough/bucking and extubation time. Methods Randomized clinical trials from MEDLINE, EMBASE, CENTRAL, and LILACS published until December 23, 2020 were included. Our primary outcome was postoperative cough/bucking incidence which was compared between local anesthetics and controls. Extubation times were likewise considered. Predisposition appraisal and subgroup, affectability investigations were likewise performed. Results The pooled analysis found a 45% reduction in cough incidence after treatment with topical airway local anesthetic (RR = 0.55; 95% CI: 0.42 to 0.72; p< 0.001). The number needed to treat (NNT) was 4.61. The intervention showed no differences in reduction of the extubation time (mean difference = -0.07; 95% CI: -0.14 to 0.28; p= 0.49). Conclusion Topical airway anesthesia demonstrated better than placebo or no medication in reducing immediate post-extubation cough/bucking. Further studies could have this objective to combine the different ways to perform better outcomes for patients. intubation events Additionally emergence postextubation post coughbucking bucking MEDLINE EMBASE CENTRAL 23 202 included controls considered subgroup performed 45 RR 0.55 055 0 55 95 CI 042 42 0.4 0.72 072 72 p 0.001. 0001 0.001 . 001 0.001) NNT (NNT 461 4 61 4.61 mean 0.07 007 07 -0.07 0.14 014 14 -0.1 0.28 028 28 0.49. 049 0.49 49 0.49) patients 2 20 0.5 05 5 9 04 0. 0.7 7 000 0.00 00 46 6 4.6 0.0 -0.0 0.1 01 1 -0. 0.2 02 4. -0 -

Abstract Waste generated from agribusiness, such as swine production, can be used in agricultural soil; however, certain technical criteria should be followed. The objective of this study was to evaluate the effects of different depths of irrigation with swine wastewater (SW), associated with the soil management system, on soil chemical attributes after two corn crop cycles. The experiments were conducted in the field, in an arrangement with two soil management systems (conventional tillage system – CTS and no-tillage system – NTS) and five depths of irrigation with SW (50%, 75%, 100%, 125% and 150% of evapotranspiration from the crop – ETc). Soil samples were collected at depths of 0–0.1 and 0.1–0.2 m to determine the pH, Ca, Mg, K, Na, Al, P, Fe, Cu and Zn at the end of each crop cycle. Soil nutrient contents increased with the application of SW irrigation in the two crop cycles and in the depths of 0–0.1 and 0.1–0.2 m, mainly with an increase of irrigation depths. No effect of the management systems was observed for the majority of the nutrients evaluated. The content of the heavy metals Cu and Zn remained below the critical limits established by the Brazilian Regulations. agribusiness production however followed SW, , (SW) field conventional notillage no NTS 50%, 50 (50% 75 75% 100 100% 125 150 ETc.

SUMMARY Cordia trichotoma, popularly known in Brazil as ‘louro-pardo’, has numerous environmental and timber-related applications. This species is naturally propagated by seeds; however, this form of propagation results in restricted seedling production due to high genetic variability associated with a low degree of forest improvement. Thus, cloning of selected adult trees is an alternative for producing high-quality plants. The aims of this work were to evaluate the emission of epicormic shoots from pruned branches and to define a protocol for the in vitro establishment of C. trichotoma selected adult trees. Propagules used in these experiments were derived from the selection of four C. trichotoma adult trees. The branches were placed in a greenhouse to induce epicormic shoots. Number of shoots according to the climatic season (autumn and spring) and shoot collection time were evaluated. Three sodium hypochlorite concentrations were evaluated for five minutes (C1 = 0.58 % active chlorine, C2 = 1.12 % active chlorine, and C3 = 2.12 % active chlorine) for in vitro establishment. Results indicated that the epicormic shoot technique could be considered viable for shoot emission of C. trichotoma, regardless of the climatic season (autumn or spring). Sodium hypochlorite solution applied for 5 minutes (1.12 % of active chlorine) was effective for the in vitro establishment of nodal segments from epicormic shoots, resulting in 61.3 % of established explants. These results are promising for the cloning of adult trees during the mature stage of development in the field without the need to cut the selected tree.

RESUMEN: Cordia trichotoma, conocida popularmente en Brasil como "louro-pardo", tiene numerosas aplicaciones ambientales y madereras. Esta especie se propaga naturalmente por semillas; sin embargo, esta forma de propagación resulta en una producción restringida de plántulas por la alta variabilidad genética asociada con un bajo grado de mejoramiento forestal. La clonación de árboles adultos seleccionados es una alternativa para producir plantas de alta calidad. El objetivo de este trabajo fue evaluar la emisión de brotes epicórmicos de ramas podadas y definir un protocolo para el establecimiento in vitro de árboles adultos seleccionados. Los propágulos utilizados se derivaron de la selección de cuatro árboles adultos y las ramas se colocaron en un invernadero para inducir brotes epicórmicos. Se evaluó el número de brotes según la época climática (otoño y primavera), el tiempo de recolección de los brotes, y tres concentraciones de hipoclorito de sodio durante cinco minutos (C1 = 0,58 % de cloro activo, C2 = 1,12 % de cloro activo y C3 = 2,12 % de cloro activo) para el establecimiento in vitro. Los resultados indicaron que la técnica de brotes epicórmicos podría considerarse viable para la emisión de brotes independientemente de la estación climática. La solución de hipoclorito de sodio (1,12 % de cloro activo) fue eficaz para el establecimiento in vitro de segmentos nodales de brotes epicórmicos, resultando en un 61,3 % de explantes establecidos. Los resultados son prometedores para la clonación de laureles durante la etapa madura de desarrollo en el campo sin necesidad de cortar el árbol seleccionado.

OBJECTIVES: The current study compared the impact of pretreatment with melatonin and N-acetylcysteine (NAC) on the prevention of rat lung damage following intestinal ischemia-reperfusion (iIR). METHODS: Twenty-eight Wistar rats were subjected to intestinal ischemia induced by a 60 min occlusion of the superior mesenteric artery, followed by reperfusion for 120 min. Animals were divided into the following groups (n=7 per group): sham, only abdominal incision; SS+iIR, pretreated with saline solution and iIR; NAC+iIR, pretreated with NAC (20 mg/kg) and iIR; MEL+iIR, pretreated with melatonin (20 mg/kg) and iIR. Oxidative stress and inflammatory mediators were measured and histological analyses were performed in the lung tissues. RESULTS: Data showed a reduction in malondialdehyde (MDA), myeloperoxidase (MPO), and TNF-alpha in the animals pretreated with NAC or MEL when compared to those treated with SS+iIR (p<0.05). An increase in superoxide dismutase (SOD) levels in the NAC- and MEL-pretreated animals as compared to the SS+iIR group (34±8 U/g of tissue; p<0.05) was also observed. TNF-α levels were lower in the MEL+iIR group (91±5 pg/mL) than in the NAC+iIR group (101±6 pg/mL). Histological analysis demonstrated a higher lung lesion score in the SS+iIR group than in the pretreated groups. CONCLUSION: Both agents individually provided tissue protective effect against intestinal IR-induced lung injury, but melatonin was more effective in ameliorating the parameters analyzed in this study.

SUMMARY: Few studies have focused on the in vitro multiplication methods for Eucalyptus cloeziana. In this work we developed an indirect organogenesis protocol to obtain micropropagated plants. The interactions of plant growth regulators in juvenile tissues were evaluated. Hypocotyl, cotyledon and root tissues obtained from in vitro germinated seedlings were subjected to combinations of α-naphthaleneacetic acid (NAA), thidiazuron (TDZ) and 2,4-dichlorophenoxyacetic acid (2,4-D). In vitro callogenesis, adventitious bud induction, shoot elongation, and ex vitro survival and rooting were evaluated. Callogenic structures were observed in all evaluated tissues. Morphogenic characteristics related to the meristematic center was observed. The tissues that presented the callus mass were subcultured in a regeneration culture medium supplemented with 1.0 mg L-1 of 6-benzylaminopurine (BAP). Only hypocotyl and cotyledon induced adventitious bud and shoot elongation. Hypocotyl subjected to 2.0 mg L-1 TDZ had the highest number of elongated shoots. The two tissues (i.e., hypocotyl and cotyledon) combined with thidiazuron were characterized by the ex vitro survival of microcuttings and by adventitious rooting. Results confirmed tissue culture efficiency for microplants production by indirect organogenesis from hypocotyl and cotyledon cultivated with TDZ, and its implementation can be an alternative for forest tree breeding programs of E. cloeziana.

RESUMEN: Pocos estudios se han centrado en los métodos de multiplicación in vitro para Eucalyptus cloeziana. En este trabajo se desarrolló un protocolo de organogénesis indirecta para obtener plantas micropropagadas. Se evaluaron las interacciones de los reguladores del crecimiento en tejidos juveniles. Los tejidos del hipocótilo, cotiledón y raíces obtenidos de plántulas germinadas in vitro se sometieron a combinaciones de ácido α-naftaleneacético (ANA), tidiazurón (TDZ) y ácido 2,4-diclorofenoxiacético (2,4-D). Se evaluaron la callogénesis in vitro, la inducción adventicia de yemas, el alargamiento de brotes, y la sobrevivencia y enraizamiento ex vitro. Se observaron estructuras calogénicas en todos los tejidos evaluados. Se observaron características morfogénicas relacionadas con la formación de centros meristemáticos. Los tejidos que presentaron la masa del callo fueron subcultivados en medio de cultivo de regeneración suplementado con 1,0 mg L-1 de 6-bencilaminopurina (BAP), y solo los tejidos del hipocótilo y cotiledón formaron yemas adventicias y brotes alargados. Los tejidos del hipocótilo sometidos a 2,0 mg L-1 de tidiazuron obtuvieron mayor número de brotes alargados. Los dos tejidos (hipocótilo y cotiledón) combinados con TDZ se caracterizaron por sobrevivencia y el enraizamiento adventicio ex vitro de las microestacas. Los resultados confirmaron la eficiencia del cultivo de tejidos para la producción de microplantas por organogénesis indirecta a partir de tejidos del hipocótilo y cotiledón cultivados con TDZ y su implementación puede ser una alternativa para los programas de mejoramiento forestal de E. cloeziana.

Resumo Duroia saccifera (Rubiaceae) ocorre na floresta Amazônica. Seus extratos apresentaram atividade antibacteriana. Para obter maiores quantidades de substâncias ativas, foram utilizados segmentos de folhas de plântulas in vitro de D. saccifera como explantes para indução de calos; os calos foram multiplicados através de múltiplos subcultivos, depois secos e extraídos com hexano, seguido por acetato de etila (AcOEt) e metanol (MeOH). Como D. macrophylla foi relatada como produtora de substâncias antimicobacterianas, os extratos de calos foram testados contra Mycobacterium tuberculosis (cepa H37Rv). O extrato AcOEt dos calos foi ativo, com uma concentração inibitória mínima (CIM) de ≤ 25 mg mL-1, IC90de 19,5 mg mL-1 e concentração bactericida mínima (MBC) de 200 mg mL-1. O extrato AcOEt foi analisado por cromatografia em camada delgada comparativa (CCDC) e Ressonância Magnética Nuclear (RMN) para determinar o seu perfil químico e mostrou ser rico em terpenos. O fracionamento cromatográfico do extrato AcOEt conduziu ao isolamento de uma mistura de dois esteroides, β-sitosterol e estigmasterol (na proporção de 2:1), os quais foram identificados por análises de RMN de 1H e bidimensionais. Pelo levantamento bibliográfico realizado, este é o primeiro relato da cultura de células in vitro de Duroia saccifera, da atividade antituberculose do extrato de calos e do isolamento de β-sitosterol e estigmasterol da cultura de células vegetais in vitro da espécie.

Abstract Duroia saccifera (Rubiaceae) occurs in the Amazon rainforest and their extracts showed antibacterial properties. To obtain greater quantities of active substances, leaf segments from in vitro D. saccifera seedlings were used as explants for calli induction; calli were multiplied via multiple subcultures, dried and extracted with hexane followed by ethyl acetate (EtOAc) and methanol (MeOH). As D. macrophylla had been reported to produce antimycobacterial substances, we assayed calli extracts against Mycobacterium tuberculosis (H37Rv strain). Calli EtOAc extract was active, with a minimal inhibitory concentration (MIC) of ≤ 25 mg mL-1, IC90of 19.5 mg mL-1 and minimal bactericidal concentration (MBC) of 200 mg mL-1. EtOAc extract was analyzed by Thin Layer Chromatography (TLC) and Nuclear Magnetic Resonance (NMR) to determine its chemical profile, and was found to be rich in terpenes. Chromatographic fractionation of the EtOAc extract yielded a mixture of two sterols, β-sitosterol and stigmasterol (in proportion of 2:1), which were identified by 1H and 13C NMR analysis. As far as we know, this is the first report of Duroia saccifera in vitro cell culture, antituberculosis activity of calli extract and β-sitosterol and stigmasterol isolation from in vitro plant cell culture.

RESUMO As blendas poliméricas obtidas com resíduos que antes eram chamados de lixos vêm crescendo como uma solução viável, permitindo melhorias nas propriedades mecânicas e como alternativas sustentáveis. Este trabalho relata os efeitos de misturas de polietileno de baixa densidade (PEBD) e borracha natural(NR), com cinzas de bagaço de cana-de-açúcar (CBCA) como carga, com e sem polietileno-enxertado com anidrido maleico (PE-g-MA) como agente de ligação. Os comportamentos dinâmico-mecânico e a análise de tensão-deformação foram estudados. Os materiais foram avaliados por calorimetria diferencial de varredura e observações morfológicas. Os resultados mostraram que a incorporação do PE-g-MA reduziu a deformação e melhorou o estresse e o módulo Young das misturas. Além disso, a presença de SCBA aumentou a dureza, mantendo a resistência à tração e o comportamento de alongamento do polímero. Os resultados demonstram o potencial uso da CBCA na mistura de elastômeros e termoplásticos, livres de agentes de vulcanização.

ABSTRACT The polymer blends obtained with residues that before were called wastes has been growing as a viable solution, allowing improvements in the mechanical properties and as sustainable alternative. This work reports the effects of blends of low-density polyethylene (LDPE) and natural rubber (NR), with sugar cane bagasse ash (SCBA) as filler, with and without polyethylene-graft-maleic anhydride (PE-g-MA) how coupling agent. The dynamic mechanical behavior and a stress-strain analysis were studied. The materials were further evaluated by differential scanning calorimetry and morphological observations. The results showed that incorporation of the PE-g-MA reduced the strain and improved the stress and the Young module of the mixtures. Moreover, the presence of SCBA increased the hardness while maintaining the tensile strength and the elongation behavior of the polymer. The results demonstrate the potential use of SCBA in the elastomer and thermoplastic mixture, free of vulcanization agents.

RESUMO Os cursos de educação médica têm implementado disciplinas e módulos que aproximem os discentes da realidade da saúde nacional, a fim de se adequarem às crescentes necessidades de reorganização da formação médica. O presente artigo relata uma experiência de acadêmicos de Medicina da Universidade Estadual de Santa Cruz (UESC) com as atividades e ações incluídas no módulo de Gestão e Rede de Atenção à Saúde, parte da Prática de Integração Ensino-Serviço-Comunidade (PIESC), como proposta de reorientação do currículo na aquisição de habilidades de liderança e gerenciamento de recursos físicos e humanos em saúde. A proposta foi inserir os discentes em diferentes níveis de complexidade tecnológica do SUS a fim de contextualizar o estudo da Rede de Atenção à Saúde (RAS) por meio de vivências e pesquisa-ação em serviços de saúde situados nos diferentes níveis de atenção. Para isso, foram realizadas entrevistas semiestruturadas com profissionais e usuários em cada ambiente visitado. Tais vivências ampliaram a visão dos acadêmicos sobre os serviços de saúde, possibilitando um melhor entendimento da estruturação da RAS, bem como um dimensionamento dos entraves encontrados nos diferentes cenários e proporcionando uma experiência in loco das críticas e dificuldades apresentadas e vividas por usuários e profissionais. Percebeu-se que não há resolutividade dos problemas de saúde dos usuários nos serviços, bem como existe uma falta de entendimento destes acerca de seus direitos e da continuidade da atenção à saúde nos diferentes níveis de atenção. Explicitou-se que as instâncias primárias de atenção não funcionam como porta de entrada adequada, o que culmina com a desestruturação da RAS observada. A experiência relatada neste artigo demonstrou um modo dinâmico de abordar a temática da Gestão e Rede de Atenção à Saúde, além de contribuir para a formação do estudante de Medicina, já que possibilitou um melhor entendimento da rede quanto às práticas em saúde e às dimensões do processo saúde-doença implicados na gestão do SUS.

ABSTRACT Medical courses in Brazil have implemented subjects and modules that aim to bring students closer to actual national health concerns, as one way of adapting to the growing needs for medical training reorganization. Thus, this article reports on the experience of medical students at the Universidade Estadual de Santa Cruz (UESC) [State University of Santa Cruz] with activities and actions included in the Health Care Network and Management module, part of the Teaching-Service-Community Intergration Practice (PIESC), as a proposal for the reorientation of the curriculum and acquisition of leadership skills and management of physical and human resources in health. The proposal was to insert the students at different levels of technological complexity of the Unified Health System (SUS) in order to contextualize the study of the Health Care Network (RAS) through experiences and action research in health services located at different care levels. Semi-structured interviews with professionals and users were therefore performed in each visited environment. These experiences served to broaden the students’ vision of health care networks, enabling a better understanding of how the services are structured, as well as of the magnitude of the obstacles found in different scenarios, providing an in loco experience of the criticisms and difficulties faced by users and professionals. It was noticed that user health problems are often not resolved within the health care services, and the users lack understanding of their health rights. A lack of continuity of the health care was also observed through the various health care levels. Thus, it is concluded that the instances of primary care fail to offer adequate gateway services, culminating in the breakdown of the observed network. The experiment reported in this article demonstrated a dynamic way to approach the issue of Health Care Network Management, contributing to medical student training, as it enabled a better understanding of the network in terms of the health practices and the dimensions of the health-disease process involved in the management of the SUS.

ABSTRACT The objective of this study was to evaluate the production performance and carcass traits of feedlot steers fed a high-energy diet supplemented with doses of an enzyme complex (0, 2.5, 5.0, and, 7.5 g animal−1 day−1). Thirty-two ½ Angus ½ Nellore crossbred steers at an average age of 12 months and an average initial weight of 422 kg, were kept in a feedlot for 77 days. The roughage-free diet was composed of a mixture of whole corn grain and a protein-mineral-vitamin mix at a constant ratio of 85:15, on a dry matter basis. A completely randomized block design was adopted, consisting of four treatments and four replicates, in which each replicate was represented by a stall with two animals. Each gram of product added to the diet led to a decrease of 0.0818 kg in daily dry matter intake (DMI), whereas fat thickness at the ribs and at the hindquarter increased by 0.3850 and 0.080 mm, respectively. Feed efficiency increased by 0.0054 kg BW kg DMI−1 per gram of enzyme added. Apparent dry matter digestibility had a quadratic response, with maximum digestion manifested at the dose of 4.78 g animal−1 day−1. The gradual inclusion of enzyme complex reduces the DMI but increases feed efficiency and carcass fat cover of feedlot steers.

Abstract On August 14, 1967, the reporter Saulo Gomes, working at TV Tupi, went to a small city in the State of São Paulo called Buritizal to investigate reports of a meteorite fall and write a newspaper report. He actually recovered three fragments of the meteorite at a small farm. In 2014, he donated one of the fragments to the Museu Nacional of the Universidade Federal do Rio de Janeiro (MN/UFRJ). We named this meteorite Buritizal and studied its petrology, geochemistry, magnetic properties and cathodoluminescence with the intent to determine the petrologic classification of the meteorite. In this manner, the Buritizal meteorite is classified as an ordinary chondrite LL 3.2 breccia (as indicated by lithic fragments). The meteorite consists of ~ 2% of metallic Fe,Ni and many well-defined chondrules with ~ 0.8 mm in average diameter. An ultramafic ferromagnesian mineralogy is predominant in the meteorite, represented by olivine, orthopyroxene, clinopyroxene, Fe-Ni alloy, troilite and glass. The total iron content was calculated as 20.88 wt%. Furthermore, the meteorite was classified as weathering grade W1 and shock stage S3. Buritizal is the 25th observed meteorite fall recovered in Brazil, of 70 meteorites known from Brazil. Thus, the study of the Buritizal meteorite is very important and relevant for the Brazilian scientific community.

RESUMO O câncer de mama pode ser considerado, atualmente, um problema de saúde pública devido a sua crescente incidência e índices de letalidade. Diante disso, o movimento Outubro Rosa visa chamar a atenção da população a respeito dessas neoplasia em mulheres de todo o mundo, de modo que suas ações têm por objetivo comum realizar o diagnóstico precoce no intuito de diminuir a mortalidade em decorrência dessa neoplasia. Dessa forma, o presente artigo objetiva relatar a experiência de acadêmicos do curso de Medicina da Universidade Estadual de Santa Cruz, no Módulo de Práticas de Integração Ensino, Serviço e Comunidade III (Piesc III), numa ação conjunta com a Equipe de Saúde da Família (ESF) de Iguape, em Ilhéus (BA), no contexto do movimento Outubro Rosa, objetivando também compartilhar considerações sobre a formação médica levantadas pelo grupo acerca da vivência descrita. No período, realizou-se abordagem inicial na sala de espera, anamnese dirigida e foi feito o exame físico das mamas das pacientes que compareceram à Unidade de Saúde da Família. A experiência não consistiu apenas em identificar pacientes com suspeita de câncer de mama e quantificar os dados, mas numa oportunidade de exercício da Educação e Comunicação em Saúde e de desenvolvimento da relação médico-paciente. Ainda permitiu aos acadêmicos reconhecer e entender melhor as dificuldades das usuárias em relação à prevenção e promoção da saúde das mamas, sendo que se observou que diversas mulheres não estavam familiarizadas com os temas abordados. O estudante de Medicina precisa compreender que o conhecimento teórico-prático se reconstrói em cada paciente com contexto histórico específico e com diferentes visões e interpretações dos conceitos de saúde e doença. Além disso, o profissional médico deve exercitar, desde a graduação, habilidades que extrapolam o ortodoxo trabalho médico, assumindo também uma postura de multiplicador de cidadania, um agente propagador de direitos e deveres.

ABSTRACT The breast cancer can now be considered a public health problem due to its increasing incidence and lethality rates. In view of this, the October Rosa mobilization aims at drawing the population’s attention regarding this neoplasm in women from all over the world, so that their common objective is to perform the early diagnosis in order to reduce mortality due to this neoplasm. Thus, the following article describes the experiences of undergraduate medical students at the Universidade Estadual de Santa Cruz (Uesc) regarding the practice module on Integrated Teaching with Community Health and Service, as part of a joint initiative with a Family Health Team in the outskirts of Ilhéus, Bahia, Brazil, within the context of the “Pink October” movement, also aiming to share thoughts on the medical degree raised by the group on the experience described. As part of the Pink October initiative, the students were given the opportunity to take a clinical approach in the waiting room, collecting information and performing physical examinations on patients who appear at the Family Health Unit. This experience was not only intended to identify patients with suspected cancer and measure the data collected, but was also designed to provide the students the opportunity to put their health education and communication skills into practice, developing the doctor-patient relationship. It also allows academics to better recognize and understand users’ difficulties in preventing and promoting breast health. In this context, it was observed that several women were not familiar with the recommended techniques for the breast self-exam (???). Medical students must understand that practical and theoretical knowledge is reconstructed with every single patient according to their specific historical context and varying viewpoints and interpretations of the concepts of health and disease. In addition, the medical professional must exercise, from the undergraduate, skills that extrapolate the orthodox medical work, also assuming a position of multiplier of citizenship, a propagating agent of rights and duties.

Sete foram suspeitas de crises agudas de HM, das quais duas não foram consideradas como HM. Nas cinco crises compatíveis com HM, todos os pacientes receberam anestésicos inalatórios halogenados (2 isoflurano, 3 sevoflurano) e um usou também succinilcolina; havia quatro homens e uma mulher, com média de idade de 18 anos (2-27). Problemas descritos nas cinco crises de HM: taquicardia (cinco), aumento do gás carbônico expirado (quatro), hipertermia (três), acidemia (um), rabdomiólise (um) e mioglobinúria (um). Um paciente recebeu dantrolene. Todos os cinco pacientes com crises de HM foram seguidos em unidade de terapia intensiva e recuperaram-se sem sequelas. A suscetibilidade à HM foi posteriormente confirmada em dois pacientes por meio do teste de contratura muscular in vitro. CONCLUSÕES: O número de chamadas por ano no serviço brasileiro de hotline para HM ainda é reduzido. As características das crises foram similares às descritas em outros países. É preciso aumentar o conhecimento sobre HM no Brasil.

BACKGROUND AND OBJECTIVES: Malignant hyperthermia (MH) is a pharmacogenetic disease that causes abnormal hypermetabolic reaction to halogenated anesthetics and/or depolarizing muscle relaxants. In Brazil, there is a hotline telephone service for MH since 1991, available 24 hours a day in São Paulo. This article analyzes the activity of the Brazilian hotline service for MH in 2009. METHODS: Prospective analysis of all phone calls made to the Brazilian hotline service for MH from January to December 2009. RESULTS: Twenty-two phone calls were received: 21 from the South/Southeast region of Brazil and one from the North region. Fifteen calls were requests for general information about MH. Seven were about suspected MH acute episodes, two of which were not considered as MH. In five episodes compatible with MH, all patients received halogenated volatile anesthetics (2, isoflurane; 3, sevoflurane) and one also used succinylcholine; there were four men and one woman, with a mean age of 18 years (2-27). The problems described in the five MH episodes were tachycardia (5), increased expired carbon dioxide (4), hyperthermia (3), acidemia (1), rhabdomyolysis (1), and myoglobinuria (1). One patient received dantrolene. All five patients with MH episodes were follow-up in the intensive care unit and recovered without sequelae. Susceptibility to MH was later confirmed in two patients by in vitro muscle contracture test. CONCLUSIONS: The number of calls per year in the Brazilian hotline service for MH is still low. The characteristics of MH episode were similar to those reported in other countries. The knowledge of MH in Brazil needs to be increased.

JUSTIFICATIVA Y OBJETIVOS: La Hipertermia Maligna (HM) es una enfermedad farmacogenética, con una reacción hipermetabólica anormal a los anestésicos halogenados y/o relajantes musculares despolarizantes. Desde 1991 existe un servicio hotline de atención telefónica para la HM en Brasil a disposición las 24 horas del día en São Paulo. Este artículo analiza la actividad del servicio brasileño de hotline para la HM en el 2009. MÉTODOS: Análisis prospectivo de todas las llamadas telefónicas realizadas al servicio brasileño de hotline para la HM, desde enero a diciembre de 2009. RESULTADOS: Se recibieron 22 llamadas; 21 provenientes del Sur y Sudeste de Brasil y una del Norte. Quince eran solicitudes de informaciones generales sobre la HM. Siete fueron sobre sospechas de crisis agudas de HM, de las cuales dos no fueron consideradas como HM. En las cinco crisis compatibles con la HM, todos los pacientes recibieron anestésicos inhalatorios halogenados (2 isoflurano, 3 sevoflurano) y uno también usó succinilcolina. Había cuatro hombres y una mujer, con un promedio de edad de 18 años (2-27). Los problemas descritos en las cinco crisis de HM: taquicardia (cinco), aumento del gas carbónico espirado (cuatro), hipertermia (tres), acidemia (uno), rabdomiólisis (uno) y mioglobinuria (uno). Un paciente recibió dantrolene. Todos los cinco pacientes con crisis de HM recibieron acompañamiento en la unidad de cuidados intensivos y se recuperaron sin secuelas. La susceptibilidad a la HM fue posteriormente confirmada en dos pacientes por medio del test de la contractura muscular in vitro. CONCLUSIONES: El número de llamadas por año al servicio brasileño de hotline para la HM todavía es pequeño. Las características de las crisis fueron similares a las descritas en otros países. Es necesario aumentar el conocimiento que se tiene sobre la HM en Brasil.
