Influência do jet lag social em marcadores circadianos de atividade - repouso e cardíaco em estudantes de medicina

Studies reveal that in recent decades a decrease in sleep duration has occurred. Social commitments, such as work and school are often not aligned to the "biological time" of individuals. Added to this, there is a reduced force of zeitgeber caused by less exposure to daylight and larger exposure to evenings. This causes a chronic sleep debt that is offset in a free days. Indeed, a restriction and extent of sleep called "social Jet lag" occurs weekly. Sleep deprivation has been associated to obesity, cancer, and cardiovascular risk. It is suggested that the autonomic nervous system is a pathway that connects sleep problems to cardiovascular diseases. However, beyond the evidence demonstrated by studies using models of acute and controlled sleep deprivation, studies are needed to investigate the effects of chronic sleep deprivation as it occurs in the social jet lag. The aim of this study was to investigate the influence of social jet lag in circadian rest-activity markers and heart function in medical students. It is a cross-sectional, observational study conducted in the Laboratory of Neurobiology and Biological Rhythmicity (LNRB) at the Department of Physiology UFRN. Participated in the survey medical students enrolled in the 1st semester of their course at UFRN. Instruments for data collection: Munich Chronotype Questionnaire, Morningness Eveningness Questionnaire of Horne and Östberg, Pittsburgh Sleep Quality Index, Epworth Sleepiness Scale, Actimeter; Heart rate monitor. Analysed were descriptive variables of sleep, nonparametric (IV60, IS60, L5 and M10) and cardiac indexes of time domain, frequency (LF, HF LF / HF) and nonlinear (SD1, SD2, SD1 / SD2). Descriptive, comparative and correlative statistical analysis was performed with SPSS software version 20. 41 students participated in the study, 48.8% (20) females and 51.2% (21) males, 19.63 ± 2.07 years. The social jet lag had an average of 02: 39h ± 00:55h, 82.9% (34) with social jet lag ≥ 1h and there was a negative correlation with the Munich chronotype score indicating greater sleep deprivation in subjects prone to eveningness. Poor sleep quality was detected in 90.2% (37) (X2 = 26.56, p <0.001) and 56.1% (23) excessive daytime sleepiness (X2 = 0.61, p = 0.435). Significant differences were observed in the values of LFnu, HFnu and LF / HF between the groups of social jet lag <2h and ≥ 2h and correlation of the social jet lag with LFnu (rs = 0.354, p = 0.023), HFnu (rs = - 0.354 , p = 0.023) and LF / HF (r = 0.355, p = 0.023). There was also a negative association between IV60 and indexes in the time domain and non-linear. It is suggested that chronic sleep deprivation may be associated with increased sympathetic activation promoting greater cardiovascular risk.

A terapia comunitária e a vivência de estudantes de medicina: uma estratégia de ensino aprendizagem do cuidado humanizado na ESF?

Before the scenario full of criticism about a medical model that gives privilege to the diseases and not to the diseased, there are many arguments that defend the need of redeem the humanized relationship between doctor and patient. It became indispensable to mold during the medical graduation a professional capable of perform a special care, less instrumental and more humanized; however, even though the advances of the pedagogical program of the medical graduation, we still face numerous challenges in the process of molding. This study has as general goal to understand if the students medicine experience with the Integrative Community Therapy (TCI) at the Primary Attention – APS/Family Healthy Strategy-ESF, presents potential to configure itself while strategy of teaching-learning to the integral and humanized care. It was held a qualitative research with the students of the medical graduation from the tenth to the twelfth semester that had experience with the TCI, as part of the Boarding of Family and Community Medicine – MFC. We used interviews with script and we resorted to analyze the narratives to Gadamerian Hermeneutics. It was possible to find that before join the boarding of MFC, the students were unaware the TCI and their preconceptions lined up with depreciated character. The experience with the TCI enabled the reframing of the prejudices and the build of new concepts. Internship in ESF and participate of TCI revealed potential to learning of the humanized care by the practical exercise with experiences that privilege the built of ties; the autonomy of the patient; the fulfillment of the longitudinality at the care of the patient; the acknowledgment of the power of resilience of the patients, at the strength of the collective, at the pain sharing, at the strength of a good communication, at the gains of qualified listening exercise. The absence of models of what to do was replaced by experiences of pains and joys at the learning of becoming a doctor. The pains spoke of the structural difficulties (inputs), at the get along with the socials vulnerabilities of the users and the difficult of perform a good communication with the patients. The joys were experienced at the finding of the humanized care exercise. Questions as structural difficulties, low number of people with TCI degree, a shortly experience of with TCI, show up as limitations to its utilization as pedagogical tool. In turn, the reflective potential is capable of cause resignifications about the know-how before the pain of the other being very much present at the narratives, signaling the potential of the learning of TCI. Therefore, this study advocate that the participation of the students at the TCI, beyond the power of offering the students a teaching-learning strategy to the humanized care, represents the possibility of enlarge the horizons of those future doctors at a glance much more conscious of the difficulties and potential of a professional at the ESF, contributing to the graduation of more sensitized professionals and prepared to perform an integral and humanized approach of the person and his/her community, contributing to an APS/ESF more resolute and rewarding to everyone.

Ensino da ultrassonografia diagnóstica a partir do ciclo básico do curso de medicina utilizando livro digital multimídia

Currently, the diagnostic ultrasound is inserted in various areas of medical action and carried out by many medical professionals, from which militate directly in the image area, such as radiologists and sonographers, but also by gynecologists, pediatricians, neurologists, general practitioners, endocrinologists, angiologists, orthopedists, rheumatologists, urologists, general and vascular surgeons. It is well known that the medical professional, for the exercise of its mission, requires a broad set of skills, competencies and attitudes developed and exercised during their training period. Living with medical students over nearly 20 years in hospital environment, I noticed gaps in the learning process by the students about what is diagnostic ultrasound and its applications, demonstrating failures as understanding the basic acoustic ultrasound, difficulties in identifying of anatomical structures in ultrasound images and inability in requests examinations and interpretations of images and reports. Based on these findings, it was developed in this Professional Masters a multimedia digital book that exposes what the ultrasound as a diagnostic modality imaging, dealing with its historiography and its physical/acoustic concepts, relating the process of formation of the ultrasound image, discussing about the features of sonographic equipments and their embedded technologies and highlighting its diagnostic applications , the latter presented through videos which will be described aspects of captured ultrasound images. This book will be available for access in digital format, serving as a teaching tool in medical education since the beginning of the course, so that can be used in conjunction with the discipline of Gross Anatomy, offered in the basic cycle of the Medicine Undergraduate Course of the Federal University of Rio Grande do Norte (UFRN).

Utilização de mapas conceituais como ferramenta de ensino para o desenvolvimento do raciocínio clínico no curso de medicina da Universidade Federal do Rio Grande do Norte

BACKGROUND: Among the wide range of skills displayed by a medical doctor is undoubtedly the need to use cohesive and well grounded clinical reasoning in order for medical care to be indeed effective. It is in this respect that conceptual maps emerge; these are a methodological innovation that allows a comprehensive, panoramic and associative outlook of theoretical content, making it more practical and applicable to the reality of clinical observation. Promoting learning, learning resources and a feedback system between professor and students, as well as assessing and monitoring the performance of students during their academic training, are the main features of this tool. OBJETIVE: Assess the use of conceptual maps as a teaching-learning tool in the training of undergraduate medical students at Universidade Federal do Rio Grande do Norte (UFRN). METHODOLOGY: Interventional, randomized, cross-sectional study conducted with students from the 3rd and 5th periods of the medical course at UFRN, during the second semester of 2014, totaling 86 participants, divided into two groups: GI (intervention – clinical case resolution with a conceptual map) and GII (control – clinical case resolution without a conceptual map) in each period. RESULTS: The use of conceptual maps to teach liver failure syndrome resulted in a statistically significant cognitive gain for G1 students from the 5th period (GI: 6.8±1.6 and 8.0±1.5, p = 0.024; GII: 7.2±2.1 and 8.0±1.7, p = 0.125, pre and post-intermediate means, respectively), a result not observed in the period 3rd (GI: 7.7±1.3 and 8.0±1.4, p = 0.501; GII: 6.7±1.8 and 7.8±1.8; p=0.068, pre and post-intermediate means, respectively). Students in the 3 rd period gave better responses to the first clinical case, with a larger number of suitable concepts and crosslinks, when they used conceptual maps (GI: 91.3±13.15 and GII: 64.84±22.84, p=0,002). Students in the 5th period exhibited better clinical reasoning and more complete responses using the tool (p=0,01). Most of the students were not aware of the tool (53.8% from the 3rd period and 65.3% from the 5th period). Among those who knew about conceptual maps, most (59.3%) had only used them during high school, 14.8% had never used them and only seven students (25.9%) used them during the medical course. Analysis of open responses, obtained in process assessment showed clear satisfaction and enthusiasm with learning about the new tool, and frequent suggestions to use it at other moments in the course. Assessment of learning profile, using the VARK questionnaire, showed that most students from both periods exhibited a multimodal style. CONCLUSION: Despite their scant knowledge regarding the tool, good acceptability and understanding was observed in the study participants. The conceptual maps allowed cognitive gains, better responses and clinical reasoning in teaching liver failure syndrome to 5th period students.

Avaliação do ensino da obstretícia e da assistência ao parto sob a percepção dos graduandos em medicina e enfermagem na Universidade Federal do Rio Grande do Norte

OBJETIVE: To evaluate the perception of Medical and Nursing students of Medicine and Nursing graduation courses at the Federal University of Rio Grande do Norte (UFRN), on obstetrics teaching and labor assistance in the context of the maternal care provided by the Maternity Hospital Januário Cicco (MEJC) and contribute to curricular updating planning of teaching obstetrics, in accordance with the principles of humanization. METHODS: It was conducted a study of cross-cutting approach and qualitative and quantitative descriptive method, with students in medicine and nursing of UFRN, who were attending or had been attended the midwifery disciplines medicine; and women's health in nursing. The data were collected through a questionnaire with objective and subjective questions, and stored in a database, spreadsheet software Excel / Office 2010 with all the variables. RESULTS: We interviewed 169 students, 118 of medical school and 51 from the nursing program, of which 46.75% were male and 53.25% female. The largest number of medical respondents is the 11th period (40.67%), and nursing, on 10, (43.15%). These students witnessed 1,073 births, and (61.8%) vaginal deliveries. The obstetricians were the most performed vaginal deliveries (40%). Nurses performed only (8.13%). The assistance provided to women during the process of labor and delivery, was configured as suitable for 87.58% of respondents and these glimpsed humane conduct. Students who performed deliveries, 76.27% were medical and 11.76% were nursing. All had guidance while doing them. A total of 19.50% medical students reported that there is a prejudice against vaginal delivery, particularly for the humanized birth, unlike all nursing students (100%) who reported that there is this prejudice. Most students (73%) showed preference for vaginal delivery, especially nursing students. On the knowledge of myths in relation to vaginal delivery, 60.35% answered that they know some. CONCLUSION: This study presents itself as a highly relevant, since the results may contribute to curricular changing and updating related to obstetrics teaching, but also serve as a resource for analysis of humanization practices that should be developed in educational institutions and which are recommended by the Ministry of Health.

A simulação como método de ensino de habilidades no curso de medicina: relato de uma experiência com punção lombar

The teaching of the lumbar puncture (LP) technique with simulator is not well systematized in the curricula of medical schools. Studies show that training in the simulator provides learning technical skills, acquisition and retention of knowledge, improve self-confidence of the learner and enables the transfer to clinical practice. We intend this study to introduce simulated training in LP in medical course at the Universidade Federal do Rio Grande do Norte evaluating the experience taking into account quantitative aspects (performance on standardized tests) and qualitative (perception of the students regarding the method and the teaching process learning). The study was conducted in two phases. In the first phase practical training in PL was introduced in the 3rd year of medical school. Seventy-seven students were trained in small groups, guided by a checklist developed in the model Objective Structured Assessment of Technical Skill (OSATS), at this moment they knew they were not under performance evaluation. They were also asked whether they had prior chances to make an LP in patients. At the end of the first phase the students evaluated training in the following areas: teaching technique, simulator realism, time available per group, number of participants per group and relevance to medical practice. In the second phase, two years later, 18 students trained in first stage performed a new LP on the mannequin simulator, and its performance was evaluated through the same checklist of training in order to verify the technical retention. In addition, they answered a multiple choice test about practical aspects of the LP technique. Each participant received individual feedback on their performance at the end of their participation in the study. In the first phase of the study we found that only 4% of students had performed a lumbar puncture in patients until the 3rd year. The training of LP technique with simulator mannequin was considered relevant and the teaching methods was thoroughly evaluated. In the second phase, all participants were successful in implementing the lumbar puncture on the mannequin simulator, compliance with the most steps in a reasonable time, suggesting that would be able to perform the procedure in a patient.

Estratégia de capacitação pedagógica do residente: uma perspectiva para melhoria do ensino na Universidade Federal do Rio Grande do Norte

Studies have shown that resident informally plays the role of teacher. It is estimated that up to 25% of the residents of the time is devoted to teaching, mainly contributing as a facilitator, however, almost the entire medical residency programs in Brazil did not offer teacher training during residency education. This paper aims to introduce educational content initiation to teaching as part of the training of resident physician inserted in residency program of the University Hospital Onofre Lopes (HUOL). It is an exploratory, descriptive and prospective study in HUOL the Federal University of Rio Grande do Norte. Three steps were developed: preparation and planning of a pedagogic course, associated with a motivating technical content (basic and advanced life support); second stage, testing of pedagogical model for medical students; and finally, replication to residents. The interventions were made two practice stations life support with performance evaluation in practical activity through OSPE (Objective Structured Practical Examination). The techniques presented teachings were one-minute preceptor and feedback. Data collection was conducted through a structured evaluation form during the life support stations and at the end of the course, and analyzed using descriptive statistics. The results showed that the feedback and one minute preceptor were considered important for teaching and learning for more than 85% of participants. The feedback from evaluators practices stations added information about the performance and were held appreciatively way, according to 100% of the participants. Positive aspects highlighted by the participants were related to educational content, especially the participants of the first intervention. The time of the lectures of motivating technical content was the most repeated negative. Based on the good acceptance of pedagogical contents, this pioneer teacher training strategy was included in the formal residency program in Cardiology of our institution. It is considered therefore that the educational training model with motivating technical content was feasible and had a good evaluation and acceptance by most participants in both interventions. Thus, we believe that the educational content can be inserted in the formal curriculum of medical residency of other programs at HUOL through the training model developed in this study.

Características de virulência, resistência e diversidade genética de sorovares de Salmonella com impacto na saúde pública, isolados de frangos de corte no Brasil /

Salmonella Enteritidis, S. Typhimurium and S. Infantis are often associated with cases of human infections worldwide and is transmitted through consumption of contaminated food, particularly those of animal origin, especially chicken meat. This thesis was fractionated into three chapters, the first one relating to general considerations about the topics discussed in the following chapters. The second chapter aimed to evaluate virulence characteristics, antimicrobial resistance and the genetic similarity of 51 strains of S. Infantis isolated in samples of poultry origin from an industry located in the state of São Paulo, Brazil, during the 2009 to 2010 period. The third chapter aimed to analyze 111 strains of S. Enteritidis, 45 of Salmonella Typhimurium and 31 of Salmonella Typhimurium monophasic variant I 4, [5], 12:i:- isolated from chicken carcasses in different brazilian slaughterhouses from 2009 to 2011, and to estimate the risk to human health, based on the presence of virulence genes and antimicrobial resistance, correlating to the pathogenicity profiles (antimicrobial resistance and presence of virulence and resistance genes) with the genetic profile (ribogroup) of the isolates. To evaluate the antimicrobial susceptibility was performed the disk diffusion test for all serotypes of Salmonella, and exclusively to S. Enteritidis and S. Typhimurium, was also verified the minimum inhibitory concentration for ciprofloxacin and ceftazidime antibiotics. The presence of virulence genes invA (invasion), lpfA (fimbriae-adhesion), agfA (fimbriae-biofilm) and sefA (fimbriae-adhesion) were evaluated by PCR. The strains that showed resistance to antibiotics of β-lactams class were evaluated for the presence of resistance genes blaTEM, blaSHV, blaCTX-M and blaAmpC. For resistant strains to quinolones and fluoroquinolones antibiotics classes were searched the qnrA and qnrS genes. The phylogenetic relationship among the isolates was determined by RAPD method for S. Infantis strains, and by ribotyping technique to S. Enteritidis and S. Typhimurium.

Acceso a medicamentos de alto precio en Brasil: la perspectiva de médicos, farmacéuticos y usuarios

Objetivo: Explorar las percepciones sobre el acceso a los medicamentos del Componente Especializado de la Asistencia Farmacéutica (CEAF) del Sistema Único de Salud brasileño (que incluye los medicamentos de alto costo), por parte de los actores involucrados en el ámbito asistencial del CEAF. Métodos: Estudio cualitativo descriptivo. Para la recolección de los datos se realizaron un grupo focal con siete usuarios/as y 11 entrevistas semiestructuradas a profesionales de la salud (medicina y farmacia) del estado de Santa Catarina. Resultados: Según los/las participantes, el acceso a medicamentos del CEAF ha mejorado. Se encontraron también dos percepciones sobre los Protocolos Clínicos y Directrices de Tratamiento del CEAF: las exigencias son burocracia que limita el acceso y los requisitos aumentan la demanda de exámenes y especialistas, superando la capacidad de la red de servicios de salud. A partir de estas percepciones se generan vías alternativas de acceso que evidencian una concepción frágil del derecho a la salud, desinformación y dependencia por parte de los usuarios, las cuales pueden tener consecuencias en la salud de las personas y en el sistema de salud. Según los/las participantes, debido a las dificultades en el acceso de los servicios de salud en general, el pleno acceso a los medicamentos aún es un objetivo por alcanzar. Conclusión: De acuerdo con las percepciones encontradas, aunque el acceso a los medicamentos del CEAF ha mejorado, persisten dificultades para garantizar su oportunidad y su integralidad.

A racionalização das condições de trabalho nos hospitais: uma análise crítica baseada em relatos de ginecologistas obstetras e pediatras atuantes na urgência e emergência

Hospitals are a big part of the service sector. Thus, such institutions are highly influenced by the logic of the capitalist accumulation, technology and forms of labor organization, especially by private organizations. Starting with the restructuring process motion and incorporation of technologies, many changes in the working process occur, therefore, the activities of medical professionals as well. During the preparation of this research items regarding the banalization of evil were identified. This banalization and resignation of the professionals face to violence are caused by the adoption of collective defense strategies. Therefore, this research aims to analyze how the rationalization of working conditions by gynecologists obstetricians and pediatricians working in the emergency rooms of public and private hospitals in Curitiba and metropolitan region occurs. An approach of mixed methods was used as methodological procedures. The naturalization of violence, the suffering which professionals are submitted to, are combined with the political and ideological control, bureaucratic control, the imaginary built about hospitals and collective defense strategies. It is therefore possible to understand that labor conditions of gynecologists obstetricians and pediatricians in emergency rooms are rationalized. When social injustice is naturalized, political strategies for changes are not possible. For this reason, the first step is to gather awareness, there is a need to unveil the reality, to understand the phenomena at its core and discard superficialities. It is also necessary that the actions and expressions of indignation to come hand in hand with political actions in order to change to happen.

Aplicação de redes neurais no Brasil: um estudo bibliométrico

As Redes Neurais Artificiais (RNA) simulam o cérebro humano ao coletar evidências empíricas e também ao preservar e permitir o uso do conhecimento experimental. Esta habilidade fez com que a aplicação da técnica atingisse um número cada vez maior de campos de estudo. Em meio às vantagens e desvantagens da adoção das RNA, este artigo se propõe a além de apresentar aspectos básicos das RNA e das implicações do seu uso, realizar um levantamento bibliométrico dos últimos dez anos, contemplando o termo “redes neurais” nos artigos científicos publicados na CAPES e SPELL. Os resultados foram classificados de acordo com a área de pesquisa e, especificamente quanto aos estudos de finanças, aprofundou-se em objetivo, amostra e resultados. Após o tratamento dos dados, foram encontradas 126 publicações, com aumento de 50% na quantidade de pesquisas publicadas entre o início e o final da década. Encontrou-se a seguinte ordem de relevância nas áreas de pesquisa: aplicações gerais; engenharia e manufatura; contabilidade e finanças; saúde e medicina e; marketing. Quanto aos estudos de finanças, em sua maioria os resultados foram melhores com o uso de RNA, sendo as maiores aplicações desta técnica em previsão de falências e estratégias para negociação em bolsas de valores.

Utilização do mapa espacial de radiação e dose acumulada como ferramenta para otimização de doses em pacientes e trabalhadores nas clínicas de medicina nuclear

This study has as general aim to propose a spatial map of doses as an auxiliary tool in assessing the need for optimization of the workplace in nuclear medicine services. As specific aims, we assessed the workers individual dosimetry; we analyzed the facilities of the nuclear medicine services; and we evaluated environment exposure rates. The research is characterized as a case study, with an exploratory and explanatory nature. It was conducted in three Nuclear Medicine Services, all established in the Northwest of the Paraná State. Results indicated that the evaluated dose rates and workers dosimetry, in all the dependencies of the surveyed services, are within the limits of annual doses. However some exceeded the limits recommended in the standard CNEN-NN 3:01 (2014). It was concluded that the spatial map dose is an important tool for nuclear medicine services because it facilitates the visualization of areas with highest concentration of radiation, and also helps in the constant review of these measures and resources, aiding in the identification of any failures and shortcomings, providing resources to correct any issues and prevent their repetition. The spatial map dose is also important for the regular inspection, evaluating if the radiation protection objectives are being met.

Historia do Brasil-Reino e Brasil-Imperio, comprehendendo :a historia circumstanciada dos ministerios, pela ordem chronologica dos gabinetes ministeriaes, seus programmas, revoluções politicas que se derão ... desde o dia 10 de março de 1808 ate 1871 ; a da conquista de Cayenna, da independencia do brasil e das constituições politicas desde 1789 ate 1834 ...

Alexandre Jose de Melo Moraes (1816-1882), foi medico Historiador e politico brasileiro. Revela-se como autor de um Compêndio de historia no ano de 1854, quando publica a obra Ensaio corografico do imperio do Brasil. O sucesso da obra levou-o a mudar radicalmente o rumo de seu interesse de assuntos tão diversos como a Medicina, Botanica e Agricultura para a Historia. Mello Moraes não tinha formação de historiador nem jamais se dedicara a pesquisa historica, porem legou seu nome a posteridade como um dos maiores amealhadores de documentos historicos relevantes. Sua obra e recheada de preocupações politicas assemelhou a tarefa de historiador a de um juiz que censura, mostra os defeitos, acusa os crimes ou louva as virtudes para a posteridade. Foi considerado um Grande colecionador e pesquisador.
