    The objective of this work is to analyze the project of the Basic Fluvial Health Unit (UBSF) from the author's elective internship experience. The work of a fluvial family health team (eSFF) was monitored along 20 riverside communities on the Tefé and Curumitá rivers, in Amazonas. To contemplate the objective of the study, the research strategy known as triangulation of methods was used, in which the elements then triangulated correspond to the narrative that characterizes and reports the experience of the elective internship; the theory, through two renowned works in the field of collective health, which are the attributes of primary care by Starfield (2002) and the taxonomy of health needs elaborated by Cecílio e Matsumoto (2006), added to the edition by Merhy (2007) ; the affections that the experience of the elective stage produced in the author. It was observed that the UBSF project as a primary care device was established considering much of what is thought about the attributes of primary care and the health needs of individuals and/or groups. It is also pointed out that problems in professional retention affect the establishment of a user-team bond and its monitoring over time. In addition, there is a difficulty for scientific medicine to dialogue with traditional and alternative care practices. Finally, it reinforces the need for studies on the organization of health services in different contexts, such as the riverside Amazon, and its visibility. And it is noteworthy that analyzing and/or evaluating innovative projects, such as the UBSF, requires also innovative analytical and evaluative instruments, under the risk that “whatever fluctuates may also be tied up”.O objetivo deste trabalho é analisar o projeto da Unidade Básica de Saúde Fluvial (UBSF) a partir da experiência de estágio eletivo do autor. Acompanhou-se o trabalho de uma equipe de saúde da família fluvial (eSFF) ao longo de 20 comunidades ribeirinhas nos rios Tefé e Curumitá, no Amazonas. Para a contemplação do objetivo do estudo utilizou-se da estratégia de pesquisa conhecida por triangulação de métodos, na qual os elementos então triangulados correspondem à narrativa que caracteriza e relata a experiência do estágio eletivo; a teoria, através de duas obras consagradas no campo da saúde coletiva, que são os atributos da atenção primária de Starfield (2002) e a taxonomia das necessidades de saúde elaborada por Cecílio e Matsumoto (2006) acrescidas da edição feita por Merhy (2007); as afecções que a vivência do estágio eletivo produziu no autor. Observou-se que o projeto da UBSF como um dispositivo da atenção básica se estabeleceu considerando grande parte do que se pensa sobre os atributos da atenção primária e as necessidades de saúde de indivíduos e/ou grupos. Aponta-se ainda que problemas na fixação profissional afeta o estabelecimento de vínculo usuário-equipe e seu acompanhamento ao longo do tempo. Além disso, há uma dificuldade da medicina científica em dialogar com práticas tradicionais e alternativas de cuidado. Por fim, reforça-se a necessidade de estudos sobre a organização dos serviços de saúde em diferentes contextos, como a amazônia ribeirinha, e sua visibilização. E ressalta-se que analisar e/ou avaliar projetos inovadores, como a UBSF, requer instrumentos analíticos e avaliativos também inovadores, sob o risco de que “aquilo que flutua também possa estar amarrado”

    Get PDF
    The use of osseointegrated implants has become an important alternative treatment approach in the rehabilitation of totally or partially edentulous patients. The classic protocol recommended to wait several months following extraction for the placement of implants. However,   the   refinement   of   surgical   techniques   and   implant   surfaces   has   allowed   for   the development of immediate post-extraction implant placement procedures. The immediate loading protocol contributes not only to decrease treatment time but also minimize the amount bone resorption. Additional advantages include easier determination of implant position, improved post-­operative  healing  in  extraction  sockets,  and  increased  patient  acceptance.  The  objective  of the present study was to describe the extraction and immediate loading of a mandibular right central incisor following a diagnosis of root fracture. Our report showed that the results obtained with immediate implant placement are feasible and predictable, and that the use of one-stage procedures results in increased patient satisfaction

    Este estudo tem como objetivo analisar a percepção de docentes que lecionam nos cursos de graduação em Ciências Contábeis do Brasil em relação à função e atuação do Comitê de Pronunciamentos Contábeis (CPC). Os resultados estão baseados na percepção de 190 professores sobre a função do CPC e sua atuação (Estudo I) e sobre a importância do CPC para a profissão contábil (Estudo II). Trata-se de uma pesquisa descritiva, realizada por meio de levantamento. Para análise dos dados recorreu-se a estatística descritiva e qui-quadrado de Pearson (Teste χ2). Com este último foi possível verificar se variáveis categóricas como região, titulação, idade, gênero, instituição em que trabalha, disciplina que leciona, ser docente de dedicação exclusiva ou ter junto outra profissão influenciaram nos padrões de respostas observados. No tocante ao Estudo I, grande parte dos docentes reconhece o CPC como entidade de classe responsável pela convergência no país, contribuindo, assim, para a melhoria da qualidade da informação contábil. A avaliação do órgão foi considerada boa, realizando um bom trabalho rumo à convergência. Os docentes não concordam que o Comitê simplesmente traduz as normas internacionais. Todavia, não existe consenso entre os professores em relação ao fato de que a velocidade com que as normas são publicadas pode estar prejudicando as discussões sobre a convergência. O Estudo II mostrou que a maior parte dos docentes concorda que o órgão permite maior participação da classe contábil na elaboração de padrões de contabilidade, o que irá fortalecer a classe contábil, atribuindo-lhe autoridade substantiva. ___________________________________________________________________________________ ABSTRACTThe main objective of this paper is to examine the perception of the teachers of undergraduate courses in Accounting in Brazil regarding the function and performance of the Accounting Pronouncements Committee (Comitê de Pronunciamentos Contábeis - CPC). The results are based on the perceptions of 190 (one hundred and ninety) teachers on the CPC function and performance (Study I) and the CPC relevance for the accounting profession (Study II). This is descriptive research, conducted through a survey. For data analysis descriptive statistics and chi-square(χ 2 test) were adopted. Adopting chi-squared test was possible to identify whether category variables such as region, status, age, gender, institution of work, the discipline taught, being a full time teacher or having another parallel profession influenced the response patterns observed. Regarding Study I, most of the teachers recognize CPC as the entity responsible for the convergence in the country, contributing, thus, to the improvement of accounting information. The entity’s evaluation was considered good, doing a good work on the convergence. Teachers don´t agree that CPC simply reflects the international standards. However, there is no consensus among the teacher in the fact that the speed at which the standards are published may be harming the discussions on convergence. Study II showed that most of the teachers agree that CPC allows more participation of the accounting professionals on elaborating accounting standards, strengthen and giving them substantive authority

    Este trabalho tem como principal objetivo analisar a percepção dos docentes que lecionam nos cursos de graduação em Ciências Contábeis do Brasil em relação ao atual processo de convergência internacional. Participaram da pesquisa 190 professores de todo país. Trata-se de uma pesquisa exploratória e descritiva do ponto de vista de seus objetivos; já quanto aos procedimentos técnicos classifica-se como um levantamento. Para a análise dos dados recorreu-se a estatística descritiva e a estatística qui-quadrado de Pearson (Teste χ2 ). Com este último foi possível verificar se variáveis categóricas como região, titulação, idade, gênero, instituição que trabalha, disciplina que leciona, ser o docente dedicação exclusivamente ou ter outra profissão influenciaram nos padrões de respostas observados. Os resultados evidenciaram que a maior parte dos docentes avalia o processo de convergência como muito importante, uma vez que reduz os custos na elaboração de informações contábeis e facilita a inserção no mercado internacional de empresas brasileiras. Para eles, o fato do país não possuir uma profissão contábil forte e atuante pode representar um obstáculo ao processo de adoção dos IFRS divide opiniões, de forma que os resultados sobre o assunto são inconclusivos. Apesar de se sentirem preparados para lecionar nessa nova realidade, eles reconhecem que as instituições educacionais brasileiras não estão. __________________________________________________________________________________________________________________ ABSTRACTThis paper is meant to examine the perceptions of teachers who teach in undergraduate courses in Accounting in Brazil in relation to the current process of international convergence. 190 teachers participated in the survey across the country. It is an exploratory and descriptive in terms of its objectives, and technical procedures have to be treated as a withdrawal. For data analysis we used descriptive statistics and chi-square test (χ2 test). With the latter it was possible to verify that categorical variables such as region, title, age, gender, institution that works, teaches discipline, be dedicated exclusively to teaching or have other profession influenced the response patterns observed. The results showed that most teachers evaluate the convergence process as very important, as it reduces costs in the preparation of accounting information and facilitates the integration into the international market for Brazilian companies. For them, the fact that the country does not have a strong accounting profession and active may represent an obstacle to the adoption process of IFRS divides, so the results are inconclusive on the subject. Although they feel prepared to teach in this new reality, they recognize that educational institutions are not Brazilian

    During the surgical and implant procedures, there is considerable risk of injury to oral nerves. The dental surgeon must recognize clinical signs of the main nerve lesions that might occur following surgical or dental implant procedures, and take the necessary precautions to prevent them. Objective: The aim of this manuscript was to describe a legal case of clinical paresthesia due to alveolar nerve compression following an implant placement, revising the types of nerve lesions of surgical-implant etiology, and advise the dental professional against clinical and legal flaws. Case report: In this case, a female patient underwent oral rehabilitation, including the placement of an osseointegrated implant in the lower left first molar region. After the setting of the device, the patient presented paresthesia on the left mentonian region and buccal mucosa of elements 34, 33 and 32 and, dissatisfied with the situation, she appealed to justice and requested the responsibility of the professional. Conclusion: It is important to discuss that prevention continues to be the key issue when it comes to avoiding clinical, ethical or legal repercussions. Practicing adequate diagnosis and treatment planning and conducting the necessary complementary exams are essential, allied to previously patients’ signed consent

    O propósito deste estudo foi analisar o comportamento da frequência cardíaca (FC) versus a carga de trabalho crescente (CTC) em teste de esteira, utilizando três modelos matemáticos (linear, linear com dois segmentos de reta e sigmóide) e verificar qual o melhor modelo que possibilita a identificação de um limiar de FC que pudesse servir de preditor para os limiares ventilatórios (LV1 e LV2). Vinte e dois homens realizaram um teste incremental (re-teste: n=12), com velocidade inicial de 5,5 km.h-1 e incrementos de 0,5 km.h-1 a cada minuto, até a exaustão. Medidas contínuas de FC e trocas gasosas foram convertidas para médias de 5 e 20 segundos. Somatória dos resíduos quadrados e quadrado médio do erro foram usados para verificar o melhor ajuste. A relação FC/CTC foi melhor representada pelo modelo Lin2 no grupo teste e re-teste (p<0,05). Foi possível identificar um ponto de deflexão de FC, utilizando o modelo Lin2 (limiar de FC) em todos os indivíduos no teste (164 ± 16,6 bpm; 83,6% FC MÁX) e no re-teste (162 ± 20,0 bpm; 83,9% FC MÁX). O limiar de FC (Lin2PDFC) ocorreu a 9,2 ± 1,3 km.h-1 (67,9% VelMÁX) e foi menor que o LV2 (LV2= 10,6 ± 1,5 km.h-1; 77,3% VelMÁX; p< 0,05), mas não diferente de LV1 (8,4 ± 1,2 km.h-1; 61,6% VelMÁX; p&gt; 0,05). Durante teste incremental em esteira, a relação FC/CTC parece ser bem descrita por uma função linear com 2 segmentos de reta, a qual permite a determinação de um limiar de FC que se aproxima do LV1.The objective of this study was to analyze the heart rate (HR) profile plotted against incremental workloads (IWL) during a treadmill test using three mathematical models [linear, linear with 2 segments (Lin2), and sigmoidal], and to determine the best model for the identification of the HR threshold that could be used as a predictor of ventilatory thresholds (VT1 and VT2). Twenty-two men underwent a treadmill incremental test (retest group: n=12) at an initial speed of 5.5 km.h-1, with increments of 0.5 km.h-1 at 1-min intervals until exhaustion. HR and gas exchange were continuously measured and subsequently converted to 5-s and 20-s averages, respectively. The best model was chosen based on residual sum of squares and mean square error. The HR/IWL ratio was better fitted with the Lin2 model in the test and retest groups (p<0.05). The Lin2 model permitted the identification of the HR threshold (Lin2HRDP) in all subjects of the test (164 ± 16.6 bpm; 83.6% HR MAX) and retest groups (162 ± 20.0 bpm; 83.9% HR MAX). Lin2HRDP (9.2 ± 1.3 km.h-1; 67.9% speedMAX) was lower than VT2 (10.6 ± 1.5 km.h-1, 77.3% speedMAX; p<0.05), but did not differ from VT1 (8.4 ± 1.2 km.h-1, 61.6% speedMAX; p&gt;0.05). During a treadmill incremental test, the HR/IWL ratio seems to be better fitted with a Lin2 model, which permits to determine the HR threshold that coincides with VT1

    Objective The objective of this study was to evaluate the local effects of statins as adjuvants for treatment by scaling and root planing (SRP) of periodontal disease induced in rats. Material and Methods Ninety rats were used in the present experiment. Periodontal disease was induced in all animals using a cotton thread placed in the left first mandibular molar. After 7 days of induction, the bandage was removed and the animals were divided into three groups: 1) NT group (n=30), no treatment; 2) SRP group (n=30): SRP and irrigation with control gel; 3) S group (n=30) - SRP and irrigation with Simvastatin. Ten animals from each group were euthanized at 7, 15 and 30 days after treatment. Gingival biopsy specimens were processed to analyze the expression of matrix metalloproteinase 8 (MMP-8). The mandibles were removed and submitted to radiographic and laboratory processing for histometric analysis. Results The S group showed a significantly lower expression of MMP-8 compared to NT and SRP groups in all experimental periods. In the radiographic and histometric analyses between the groups, S group showed a significantly lower bone loss (BL) compared to NT and SRP groups in all experimental periods. Conclusions Within the limits of this study, it can be concluded that locally applied statin was effective as an adjuvant treatment for SRP in rats with induced periodontal disease

    Objective. Evaluate the productivity, sweet maize plants characteristics, crude protein and economic indicators of the production of sweet maize silage inoculated with Azospirillum brasilense and thiamine as seed treatment (0; 15; 30; 45 mg kg-1). Material and Methods. Biometric characteristics, productivity, crude protein content were evaluated, and the total operational cost structure was used to determine the economic indexes of a productive cycle. Results. It was observed that treatments with isolated or combined application of A. brasilense and thiamine did not affect the plant height, stem diameter, fresh and dry mass productivity and crude protein contents of sweet maize plants. However, the inoculation with A. brasilense increased in 24.36%, 24.36%, 53.15% and 10.47%, the productivity of fresh matter, gross revenue, operating profit and the profitability index, respectively, compared to the control treatment. Even with different responses, all treatments resulted in positive profitability indices, indicating the appropriate economic return with this activity. Conclusions. It was concluded that A. brasilense and thiamine applied as seed treatment do not significantly affect sweet maize plants development and composition; treatments influenced the economical indexes, and the isolated application of A. brasilense resulted in higher earnings; thiamine isolated application as seed treatment can be used as an alternative for improvement of economical gains.Objetivo.

    Objective: This study aims to understand the social representations of old age LGBT (lesbians, gays, bisexuals, transvestites, and transgenders) among adults living with human immunodeficiency virus (HIV) in Brazil. Method: 111 people from 21 Brazilian states participated in the study, with a mean age of 42 years, most of the men (85%), homosexuals (75%), single (85%), and without religion (34%). For data collection, a sociodemographic questionnaire was used; a structured interview was also used; both instruments were applied online. Results: The classes of representations shared by the investigated group are structured in three main axes: Old age of LGBT people; Old age of people living with HIV; Intersectionality, and commonalities between groups. Conclusions: The representations directed to the specificities of each group were: Older LGBT people, connected to loneliness and discrimination; People living with HIV, related to the continuous use of medication. The common and intersectoral experiences for both groups are those related to the experience of stigma and social exclusion. Thus, based on the representations expressed, one can see the need for an intersectional understanding of the groups being investigated and the importance of countering the negative stereotypes to which these people are subjected.Objetivo: Este estudo teve como objetivo compreender as representações sociais da velhice LGBT (lésbicas, gays, bissexuais, travestis e transexuais) entre adultos vivendo com vírus da imunodeficiência humana (VIH) no Brasil. Método: Participaram do estudo 111 pessoas de 21 Estados brasileiros, com média de idade de 42 anos, a maioria homens (85%), com orientação sexual homossexual (75%), solteiros (85%) e sem religião (34%). Para a coleta de dados foi utilizado um questionário sociodemográfico, também foi utilizada uma entrevista estruturada; ambos os instrumentos foram aplicados online. Resultados: As classes de representações partilhadas pelo grupo investigado se estruturam em três eixos principais: Velhice de pessoas LGBT; Velhice de pessoas que vivem com VIH; Interseccionalidade e pontos em comum entre os grupos. Conclusões: As representações direcionadas às especificidades de cada grupo foram: Idosos LGBT, ligados à solidão e discriminação; Pessoas vivendo com VIH, relacionadas com o uso contínuo de medicamentos. As experiências comuns e intersetoriais para ambos os grupos são as relacionadas com a vivência do estigma e da exclusão social. Assim, a partir das representações apreendidas, percebe-se a necessidade de uma compreensão interseccional acerca dos grupos investigados, tal como, a importância de trabalhar no combate aos estereótipos negativos aos quais esses sujeitos são submetidos
