OBJECTIVE: Parasympathetic dysfunction is an independent risk factor in individuals with coronary artery disease, and cholinergic stimulation is a potential therapeutical option. We determined the effects of pyridostigmine bromide, a reversible anticholinesterase agent, on electrocardiographic variables of healthy individuals. METHODS: We carried out a cross-sectional, double blind, randomized, placebo-controlled study. We obtained electrocardiographic tracings in 12 simultaneous leads of 10 healthy young individuals at rest before and after oral administration of 45 mg of pyridostigmine or placebo. RESULTS: Pyridostigmine increased RR intervals (before: 886±27 ms vs after: 1054±37 ms) and decreased QTc dispersion (before: 72±9ms vs after: 45±3ms), without changing other electrocardiographic variables (PR segment, QT interval, QTc, and QT dispersion). CONCLUSION: Bradycardia and the reduction in QTc dispersion induced by pyridostigmine may effectively represent a protective mechanism if these results can be reproduced in individuals with cardiovascular diseases.

A epilepsia é uma das causas mais freqüentes de distúrbios neurológicos em adultos jovens. Relatamos um caso em que uma paciente conviveu durante doze anos com o diagnóstico de epilepsia resistente ao tratamento, quando, na verdade, a causa de seus sintomas pôde ser encontrada com a realização do teste de inclinação (tilt teste). O cardiologista deve estar alerta para o possível diagnóstico de síncope neurocardiogênica em pacientes previamente diagnosticados como portadores de epilepsia, especialmente naqueles com difícil controle terapêutico.Epilepsy is one of the most frequent causes of neurological disorders in young adults. We report the case of a patient who lived with the diagnosis of refractory epilepsy for twelve years, when actually the cause of the symptoms could be found with the performance of a tilt table test. Cardiologists should be aware of the possible diagnosis of neurocardiogenic syncope in patients previously diagnosed with epilepsy, especially in those with difficult therapeutic control.

Abstract Background: The occurrence of minute-ventilation oscillations during exercise, named periodic breathing, exhibits important prognostic information in heart failure. Considering that exercise training could influence the fluctuation of ventilatory components during exercise, we hypothesized that ventilatory variability during exercise would be greater in sedentary men than athletes. Objective: To compare time-domain variability of ventilatory components of sedentary healthy men and athletes during a progressive maximal exercise test, evaluating their relationship to other variables usually obtained during a cardiopulmonary exercise test. Methods: Analysis of time-domain variability (SD/n and RMSSD/n) of minute-ventilation (Ve), respiratory rate (RR) and tidal volume (Vt) during a maximal cardiopulmonary exercise test of 9 athletes and 9 sedentary men was performed. Data was compared by two-tailed Student T test and Pearson´s correlations test. Results: Sedentary men exhibited greater Vt (SD/n: 1.6 ± 0.3 vs. 0.9 ± 0.3 mL/breaths; p < 0.001) and Ve (SD/n: 97.5 ± 23.1 vs. 71.6 ± 4.8 mL/min x breaths; p = 0.038) variabilities than athletes. VE/VCO2 correlated to Vt variability (RMSSD/n) in both groups. Conclusions: Time-domain variability of Vt and Ve during exercise is greater in sedentary than athletes, with a positive relationship between VE/VCO2 pointing to a possible influence of ventilation-perfusion ratio on ventilatory variability during exercise in healthy volunteers.

Abstract Aim: Swimming races outside swimming pools take place all over the world, but studies focusing on their physiological aspects are scarce. In fact, rules forbid any direct contact with swimmers during sanctioned events. This case report presents heart rate responses of a master athlete during an ultra-endurance open water solo swim and analyzes results based on a prior cardiopulmonary exercise test. Methods: The swimmer performed a cardiopulmonary exercise test on a treadmill, following a ramp protocol, with continuous electrocardiogram recording. The athlete performed a 36 km swimming race with continuous heart rate recording. Description of swimming heart rate accordingly to heart rate training zones and correlation analysis between HR and swim speed was assessed. Results: The athlete swam the 36 km event in 11 hours, 16 minutes and 15 seconds. Most of the swim time was spent in training zone 3 (55%), and only 2% of race time was spent in zone 5. Swimming speed (3.2 ± 0.7 km/h) failed to correlate with HR during the event (r2 = 0.1334, p > 0.05). Conclusion: Although HR did not correlate with swimming speed it successfully indicated exercise intensity during this 36 km event. These results can be used in the preparation and monitoring of other solo long-distance swimmers.

Objetivos. Analisar a produção científica existente, descrevendo os fatores intrínsecos e extrínsecos relacionados aos motivos que levam os usuários classificados como não urgentes, segundo o protocolo de ACCR, à procurem o atendimento nas UPA. Método. Trata-se de uma revisão integrativa de literatura, realizada nas bases de dados PUBMED e BVS e Google acadêmico, utilizando descritores específicos para cada base. Foram incluídos artigos completos, publicados entre 2010 e 2021 e disponíveis nos idiomas português, espanhol e inglês, sendo excluídos os artigos de revisões, teses, dissertações, artigos duplicados e os estudos que não contemplavam o tema em questão. Após a aplicação dos critérios de elegibilidade, foram selecionados 6 artigos. Resultados. Foram identificados 12 fatores, sendo 4 intrínsecos (33,3%) e 8 extrínsecos (66,6%), demonstrando que os fatores relacionados à estrutura e forma de funcionamento das unidades que compõem a RAS influenciam em maior grau essa procura equivocada por atendimento nas UPA. Por outro lado, fatores intrínsecos, relacionados à percepção do paciente, não devem ser negligenciados uma vez que também propiciam reflexões quanto às intervenções práticas à serem desenvolvidas. Conclusão. Os fatores apresentados refletem diferentes frentes de ação capazes de reverter o quadro de descaracterização de atendimentos nas UPA.

Objetivos. Analisar a produção científica existente sobre a percepção dos usuários quanto aos aspectos positivos e negativos relacionados ao Acolhimento e Classificação de Risco (ACCR) realizado nas UPA, com vistas a subsidiar a reflexão e o aprimoramento do serviço prestado. Método. Trata-se de uma revisão integrativa de literatura, realizada nas bases de dados PUBMED, BVS e Google acadêmico, utilizando descritores específicos para cada base. Foram incluídos artigos completos, publicados entre 2010 e 2021 e disponíveis nos idiomas português, espanhol e inglês, sendo excluídos os artigos de revisões, teses, dissertações, artigos duplicados e os estudos que não contemplavam o tema em questão. Após a aplicação dos critérios de elegibilidade, foram selecionados 7 artigos. Resultados. Os aspectos positivos identificados traduzem o esforço realizados pelos profissionais, mesmo em condições inapropriadas, de exercerem suas práticas de forma humanizada e acolhedora. Por outro lado, os problemas identificados caracterizam uma rede de atenção fragmentada e pouco resolutiva, que não tem conseguido atuar de forma preventiva, nem atender as demandas da população em tempo hábil. Diferentes recomendações práticas foram propostas, porém o grande desafio é sua operacionalização em um cenário de restrições. Conclusão. Revela-se a necessidade de reflexões para além dos muros das UPAS, através de uma análise crítica por parte dos gestores, sobre a necessidade de intervir a nível de Rede de Atenção à Saúde, tendo em vista que todos os elementos que a compõem precisam estar funcionando adequadamente e de forma articulada para que nenhum deles se sobrecarregue.

The World Health Organization declared that the new coronavirus outbreak is a public health emergency of pandemic proportions. The outbreak has caused various governments to take protective measures such as lockdown of cities, travel bans, prohibition of group gatherings and public events, and social distancing. Many health and exercise training facilities were closed, as well as cardiac rehabilitation services. These restrictions are disrupting people’s daily activities. Although staying at home can contain virus spread, it will certainly reduce regular physical [...]

Apresentam-se, neste estudo, os números relativos ao controle de doping em nosso país, em competição e fora de competição do ano de 2003, e consideram-se as ações preventivas desenvolvidas. Todos os controles foram feitos de acordo com as técnicas e procedimentos orientados pela Agência Mundial Antidoping (AMA), sendo então realizada uma estatística descritiva dos mesmos. Os resultados mostram 3.797 exames realizados, sendo 3.266 controles em competição e 531 fora de competição, com caráter de surpresa. A maior parte dos controles em competição (92,1%) e fora dela (92,4%) foi realizada pelo LAB DOP, da Universidade Federal do Rio de Janeiro (UFRJ). O futebol profissional foi responsável por grande parte dos controles em competição, 2.975 (91,1%), apresentando oito positivos e um percentual baixo de 0,27%, quando comparado com dados da literatura internacional. A grande maioria dos controles fora de competição foi realizada pelo Comitê Olímpico Brasileiro (COB), durante a preparação de nossos atletas para os XIV Jogos Pan-Americanos, na República Dominicana (92,4%). Foram encontrados 19 exames positivos nos controles em competição e seis positivos fora de competição, dentre os quais dois atletas de eqüestre que se negaram a ceder uma amostra biológica. O percentual encontrado em competição (0,5%) é menor do que o descrito internacionalmente, que é de 1,80, com exceção da luta de braço (30%), do tênis de mesa paraolímpico (10%), do atletismo (6,1%) e do ciclismo (4,6%). Nos exames fora de competição, foi observada uma incidência maior do que a descrita internacionalmente no fisiculturismo (33,33%), em eqüestre (22,2%), no boxe (7,6%). Na natação (2,5%) e no atletismo (1,8%), estão um pouco elevados e a média encontrada (1,1%) pode ser descrita como estando ainda na média internacional (0,9%). Os trabalhos de prevenção do COB, da Confederação Brasileira de Futebol (CBF) e do LAB DOP da UFRJ são referidos no presente artigo, juntamente com a nova legislação antidoping proposta pelo Ministério do Esporte.El presente estudio presenta los números relativos al control de dopaje en nuestro país, en competencia y fuera de competencia en el año 2003, considerando además las acciones preventivas desarrolladas.

Dentro de los cuales dos de los atletas de ecuestre se negaron a brindar la muestra biológica. El porcentaje encontrado en competencia (0,5%) es menor que el que se describe internacionalmente que es de 1,8%, con excepción de la lucha (30%), del tenis de mesa paralimpico (10%), del atletismo (6,1%) y del ciclismo (4,6%). En los exámenes fuera de competencia se ha observado una incidencia mayor que la descripta internacionalmente en el fisicoculturismo (33,33%), en ecuestre (22,2%), en boxeo (7,6%). En natación (2,5%) y en atletismo (1,8%), están un poco elevados de la media encontrada (1,1%) lo que lo podría definir como estando en la media internacional (0,9%). Los trabajos de prevención del COB, de la Brasileña de Fútbol (CBF) y del LAB DOP de la UFRJ están referidos en el presente artículo juntamente con la nueva legislación antidopaje propuesta por el Ministerio del Deporte.This study presents the statistics of doping control, in- and out-of-competition in Brazil during the year 2003 and also shows the preventive actions developed. We have asked four laboratories and their coordinators to inform us about the controls on Brazilian athletes performed during the year 2003. All controls were performed under the World Anti-doping Agency's (WADA) rules and regulations. Our results show that 3,797 controls were performed in this year, being 3,266 in-competition and 531 out-of-competition controls. Most of the in-competition (92.16%) and out-of-competition tests (92.47%) were performed by LAB DOP, the doping control laboratory of the Chemical Institute of the Rio de Janeiro Federal University (UFRJ), one of the South American accredited laboratories. Professional soccer was the sport where most of the in-competition controls were performed (2.975 = 91.1%), with eight positive findings and a very low percent of positives (0.27%) when compared to the international literature. Most of the out-of-competition tests were performed by the Brazilian Olympic Committee (COB), during the preparation of our athletes for participating in the XIV Pan-American Games, at the Dominican Republic (92.47%). The positive result found was 19 positive in in-competition test and six in out-of-competition test. Two equestrian athletes refused to be tested. The percentage of positive in-competition (0.58%) is lower than the international percentages described, that ranges from 1 to 2%, with the exceptions of arm-fighting (30%), Paralympics table-tennis (10%), track and field (6.15%) and cycling (4.69%). The out-of-competition tests were found to have a greater incidence of positive results in bodybuilding (33.33%), equestrian (22.22%) and boxing (7.69%). The results of swimming (2.56%), track and field (1.89%) were in agreement with international data. The preventive actions of COB, the Brazilian Soccer Confederation and LAB DOP were shown in this article, altogether with the new anti-doping law from the Brazilian Sports Ministry.
