Resumo A Educação a distância é uma modalidade de ensino e aprendizagem que possibilita a formação de estudantes em espaços e tempos distintos. Introdução: Nessa perspectiva é apresentado o curso de formação de supervisores e tutores, realizado na modalidade a distância no ambiente virtual de aprendizagem Moodle, da Universidade Federal do Rio Grande do Sul, do Brasil. O curso é composto por 10 módulos e cada módulo tem a duração de 30 dias. Os participantes da pesquisa realizam a parte teórica no Moodle e a parte prática num curso voltado a trabalhadores da saúde que ocorre em todo o território nacional. Objetivo: Analisar a percepção dos cursistas sobre as suas aprendizagens no curso de formação de supervisores e tutores na modalidade a distância. Método: É um estudo descritivo com abordagem qualitativa de análise temática. A coleta de dados foi realizada a partir do questionário COLLES (Constructivist Online Learning Environment Survey) online aplicado no quinto módulo, para orientar possíveis reconstruções das atividades até o final do curso. Foi utilizada a questão aberta para a análise deste artigo. Resultados: Obtivemos 4190 respostas no total de 4400 cursistas, destas 639 participantes responderam também a uma questão aberta que solicitava comentários a respeito do curso de formação. Na análise temática textual foram elencadas duas categorias: aprendizagem e educação permanente em saúde. Conclusão: O curso de formação possibilitou diversas aprendizagens dentre elas aprimorou a qualidade dos processos de mediação e feedbacks nos fóruns e nas atividades propostas. A aprendizagem na modalidade a distância apresenta-se muitas vezes como um desafio, porém gradualmente os tutores e supervisores avançaram na superação destes, seja pelo apoio das equipes do Curso, por um maior conhecimento da realidade que estão inseridos e das necessidades dos estudantes, pela análise dos resultados das propostas em ação ou mesmo por essa conjunção de fatores.

Abstract Distance education is a teaching and learning modality that enables the training of students in different spaces and times. Introduction: In this perspective, the training course for supervisors and tutors is presented, carried out in the distance mode in the virtual learning environment Moodle, at the Federal University of Rio Grande do Sul, Brazil. The course has the duration of 10 modules, each module lasting 30 days. The research participants carry out the theoretical part in Moodle and the practical part in a course aimed at health workers which takes place throughout the national territory. Objective: To analyze the perception of course participants about their learning in the training course for supervisors and tutors in the distance modality. Method: It is a descriptive study with a qualitative approach of thematic analysis. Data collection was carried out from the online COLLES questionnaire (Constructivist Online Learning Environment Survey) applied in the fifth module, to guide possible reconstructions of activities until the end of the course. Results: A total of 4190 responses were obtained from 4400 participants, of which 639 participants also responded to an open question that requested comments about the training course. In the thematic textual analysis, two categories were listed: learning and continuing education in health. Conclusion: The training course enabled several learning opportunities, among which it improved the quality of mediation and feedback processes in the forums and proposed activities. Distance learning often presents itself as a challenge, but gradually tutors and supervisors have made progress in overcoming these challenges, whether through the support of the Course teams, through greater knowledge of the reality in which they are inserted and the needs of the students, through the analysis of the results of the proposals in action or even through this combination of factors.

ABSTRACT Knowing the distribution and spatial pattern of species within a plant community is essential for planning conservation strategies and establishing sustainable management measures in forest formations, especially in Caatinga areas. In this sense, the aim of the study was to analyze the structure and spatial distribution of Pilosocereus pachycladus F. Ritter subsp. pernambucoensis (F. Ritter) in natural populations in areas of Caatinga and Brejo vegetation in the semi-arid region of Paraíba, in the municipalities of Bananeiras and Arara, respectively. In the study areas, 25 plots of 20 m x 20 m were demarcated, totaling a sample area of 10,000 m2 (1 ha). Within the plots, all individuals were labeled and the total height and circumference were measured at the base of the stem using a measuring tape. The spatial structure of the populations was obtained by collecting the geographic coordinate of each individual in each area and expressed through maps of spatial distribution. 61 specimens were sampled in the Caatinga of Bananeiras, with an absolute density of 61 ind.ha-1 and absolute frequency (FA) of 52%. 64 specimens were sampled in the Caatinga of Arara, with an absolute density of 64 ind.ha-1 and absolute frequency (FA) of 56%. The two populations were arranged in a cluster pattern (Pi = 3.74 and 3.47, respectively). P. pachycladus subsp. pernambucoensis of the two areas have a habit of aggregate growth and population structure with few regenerating individuals. Regional conservation actions for Cactaceae species in their habitat need to take these findings into account to ensure the survival of these species.

RESUMO Conhecer a distribuição e o padrão espacial de espécies dentro de uma comunidade vegetal é imprescindível para o planejamento de estratégias de conservação e estabelecer medidas de manejo sustentável em formações florestais, sobretudo em áreas de Caatinga. Nesse sentido, o objetivo do estudo foi analisar a estrutura e a distribuição espacial de Pilosocereus pachycladus F. Ritter subsp. pernambucoensis (F. Ritter) em populações naturais em áreas de Caatinga e de Brejo no Semiárido Paraibano, nos municípios de Bananeiras e Arara, respectivamente. Nas áreas de estudo, foram demarcadas 25 parcelas de 20 m x 20 m, totalizando uma área amostral de 10.000m2 (1 ha). Dentro das parcelas, todos os indivíduos foram etiquetados e a altura total e a circunferência foram auferidas ao nível da base do caule com auxílio de uma fita métrica. A estrutura espacial das populações foi obtida pela coleta da coordenada geográfica de cada indivíduo em cada área e expressa por meio de mapas de distribuição espacial. Foram amostrados 61 espécimes na Caatinga do município de Bananeiras, apresentando densidade absoluta de 61 ind.ha-1 e frequência absoluta (FA) de 52%. Foram amostrados 64 espécimes no bioma do município de Arara, apresentando densidade absoluta de 64 ind.ha-1 e frequência absoluta (FA) de 56%. As duas populações estavam dispostas em padrão de agrupamento (Pi = 3,74 e 3,47, respectivamente). Os indivíduos de P. pachycladus subsp. pernambucoensis das duas áreas possuem hábito de crescimento agregado e estrutura populacional com poucos indivíduos regenerantes. As ações regionais de conservação das espécies de Cactaceae em seu habitat precisam levar em consideração essas descobertas para garantir a sobrevivência dessas espécies.

Aim The study aimed to evaluate the accuracy of the maximum bilateral molar bite force and the Root Mean Square (RMS) Electromyography (EMG) index of the masticatory muscles in the maximum bilateral molar bite (MMBMax) of women with myogenic Temporomandibular Disorder (TMD) and asymptomatic. Methods This is a cross-sectional study, composed of 86 women allocated to the TMD Group (n=43) and Control Group (n=43) diagnosis through the Diagnostic Criteria for Temporomandibular Disorders. The maximum bilateral molar bite force was evaluated using a bite dynamometer and the RMS EMG index of the masticatory muscles (anterior temporalis, masseter) during 5 seconds of the MMBMax task. Student t-test was used for data comparison between accuracy of the bite force and RMS EMG of masticatory muscles during the MMBMax. Results The maximum bilateral molar bite force showed high accuracy (AUC=0.99) for the diagnosis of women with myogenic TMD and asymptomatic women, and the RMS EMG index evaluated during the MMBMax showed a moderate level of accuracy for all masticatory muscles (AUC=0.70 to 0.75). Conclusion The bilateral bite dynamometer with a surface EMG during bilateral bite can be used to diagnose TMD in young women.

ABSTRACT. Wooden breast myopathy (WB) strongly affects the poultry industry mainly in terms of consumers rejection and economical loses, due to morphological changes in broiler muscle tissue and consequently low meat quality. The aim of this study is to evaluate the histomorphometry of muscle fibers of breast fillets of broilers with severity levels of WB myopathy. The histological evaluation considered 30 samples of the pectoralis major muscle and the level of WB myopathy (ten normal fillets, ten moderate fillets, and ten severe fillets). Fillets with a severe level of WB present low average fiber number, high average fiber diameter, low percentage of fibers with diameter of less than 20 µm, low percentage of fibers with diameter between 20 and 40 µm, and high percentage of fibers with diameter between 40 and 70 µm. Fiber cross-sectional area is greater in fillets affected by moderate and severe WB. Thus, fillets with a severe level of WB damage the muscle fiber structure and contribute more severely to the degenerative processes of breast meat.

Abstract The induction of polyploidy in Eucalyptus can lead to higher-yielding and more adapted clones, with better wood quality. After artificial polyploidization, it is necessary to certify the effectiveness of the process through cytogenetic analyses and anatomical trait evaluations. Thus, the aim of this study was to certify the chromosome duplication in artificially polyploidized clones of Eucalyptus grandis × Eucalyptus urophylla using cytogenetic analysis, flow cytometry, and leaf anatomy measurements. Chromosomal counts and DNA content estimation allowed the identification of artificially polyploidized clones and mixoploids. Polyploid clones had larger stomata diameter than diploids. The increase in stomata size was accompanied by lower stomatal density in most polyploid clones. The typical gigas effect of polyploidized plants was demonstrated by the expressive increase in leaf area in polyploid individuals compared to diploids. Our findings indicate that the use of polyploidy in Eucalyptus breeding is promising, allowing the discrimination of diploid, tetraploid, and mixoploid plants.

ABSTRACT The objective of this study was to determine the energy values and metabolizability of different lipid sources in the diet of Japanese quail at the laying phase. The quail were distributed in a completely randomized design with ten replications of seven poultry per treatment, totaling six treatments: basal feed (control) and basal feed containing 10% soybean oil, corn oil, canola oil, sunflower oil, and poultry fat. The values of nitrogen-corrected apparent metabolizable energy (AMEn) and the metabolizability coefficient (MC%) were evaluated. No significant difference was found between the different lipid sources for AMEn (kcal/kg) and MC (%). The value of metabolizable energy corrected for nitrogen for soybean oil was 8,790 kcal/kg; 8,773 kcal/kg for corn oil; 8,784 kcal/kg for canola oil; 8,788 kcal/kg for sunflower oil; and 8,681 kcal/kg for poultry fat in laying Japanese quail. The digestibility coefficients were 93.88% for soybean oil, 93.53% for corn oil, 93.32% for canola oil, 93.74% for sunflower oil, and 93.06% for poultry fat.

There is no consensus on the most appropriate method for normalizing electromyography (EMG) signals from masticatory muscles during isotonic activity. Aim To analyze the best method for data processing of the EMG signal of the masticatory muscles during isotonic activity (non-habitual chewing), comparing raw data and different types of normalization. Methods This is a cross-sectional study. Women aged between 18 and 45 years were selected. Anthropometric data were collected (age, height, body mass index – BMI, masticatory preference) as well as EMG signal (root mean square – RMS) data for the anterior temporal and masseter bilaterally, and for the suprahyoid muscles, during isotonic (non-habitual chewing) and isometric tasks. EMG data were processed offline using Matlab® Software. The normalization of the EMG signal was carried out using the 2nd masticatory cycle, chosen at random, of the 20 cycles collected, the maximum RMS value, and the maximum voluntary contraction (MVC). To analyze the best method of data processing for the isotonic data, the coefficient of variation (CV) was calculated. Descriptive data analysis was adopted, using the mean and standard deviation. ANOVA with repeated measures was used to detect significant differences between the methods of normalization. Statistical significance was set at 5% (α<0.05). Results The final sample of this research was composed of 86 women. The volunteers presented an average age of 27.83±7.71 years and a mean BMI of 22.85±1.91 Kg/m2. Regarding masticatory preference, 73.25% reported the right side, and 26.75% the left side. Considering the comparison between the methods, the %CV measure of the 2nd cycle showed the lowest variation coefficient during biting for all the muscles from the raw data, RMS Max, and MVC (p=0.001, p=0.003, and p=0.001 respectively). Conclusion In conclusion, for non-habitual chewing activity, the results of this study recommend data processing using normalization with the second cycle during chewing.

ABSTRACT Purpose: To evaluate the effects of the experimental subcutaneous Walker-256 tumor and L-glutamine supplementation, an antioxidant, on the glomerular morphology of rats. Methods: Twenty Wistar rats were distributed into four groups (n = 5): control (C); control treated with 2% L-glutamine (CG); rats with Walker-256 tumor (WT); and rats with Walker-256 tumor treated with 2% L-glutamine (WTG). Renal histological samples were submitted to periodic acid-Schiff and Masson’s Trichrome staining to analyze glomerular density, morphometry of glomerular components and glomerulosclerosis; and to immunohistochemistry for fibroblast growth factor-2 (FGF-2). Results: WT showed 50% reduction in body mass gain and cachexia index > 10%, while WTG demonstrated reduction in cachexia (p < 0.05). WT revealed reduction of glomerular density, increase in the glomerular tuft area, mesangial area, matrix in the glomerular tuft, decrease in the urinary space and synechia, and consequently higher glomerulosclerosis (p < 0.05). L-glutamine supplementation in the WTG improved glomerular density, and reduced glomerular tuft area, urinary space, mesangial area, and glomerulosclerosis compared to WT(p < 0.05). WT showed higher collagen area and FGF-2 expression compared to C (p < 0.05). WTG presented lower collagen fibers and FGF-2 expression compared to WT (p < 0.05). Conclusions: L-glutamine supplementation reduced cachexia and was beneficial for glomerular morphology of the rats, as well as it reduced kidney damage and improved the remaining glomeruli morphology.

Abstract This study aims to evaluate the residual effect of different lipid sources in the diet of Japanese quails (Coturnix japonica) in the rearing phase on the performance and egg quality in the initial phase of egg-laying. In the first stage, 400 Japanese quails aged 21 days were used, being distributed in a completely randomized experimental design, with five treatments and ten replicates of eight birds/replicate Treatments consisted of basal ration (BR) with 2.5% soybean oil; BR with 2.5% corn oil; BR with 2.5% cottonseed oil; BR with 2.5% sunflower oil; and BR with 2.5% canola oil. At 42 days, maintaining the initial design, all quails received a basal ration with soybean oil, in order to evaluate the residual effect of the previous phase on the performance and egg quality in the initial phase of egg-laying (43 - 84 days). The different lipid sources did not affect the performance of quails in the initial phase of production. For egg quality, yolk height, yolk diameter, yolk index, gravity, and Haugh unit (HU) showed better results in the treatment using sunflower oil. There was a residual effect of the use of lipid sources of vegetable origin in the rearing phase diet of Japanese quails on egg quality traits. Lipid sources from soybean, corn, cottonseed, canola, and sunflower seeds can be used as energy sources in the rearing diet of egg-laying quails for not being harmful to their initial performance. The longevity in egg production of quails fed with different lipid sources in the rearing phase was similar.

Resumo A pesquisa foi conduzida com objetivo de avaliar o efeito residual de diferentes fontes lipídicas na dieta de codornas japonesas (Coturnix japonica) na fase de recria sob o desempenho e a qualidade de ovos na fase inicial de postura. Na primeira etapa foram utilizadas 400 codornas japonesas com idade de 21 dias, as aves foram distribuídas em tratamentos seguindo um delineamento inteiramente casualizado com dez repetições, de oito aves, em cinco tratamentos: ração basal (RB) com 2,5% de óleo de soja, RB com 2,5 % de óleo de milho, RB com 2,5% de óleo algodão, RB com 2,5% de óleo de girassol e RB com 2,5% de óleo de canola. Aos 42 dias mantendo o delineamento inicial, todas aves receberam ração basal com óleo de soja, para que fosse avaliado o efeito residual da fase anterior sobre o desempenho e a qualidade dos ovos na fase inicial de postura (43 - 84 dias). As diferentes fontes lipídicas não afetaram o desempenho das aves na fase inicial de produção. Para a qualidade dos ovos, os parâmetros de altura, diâmetro e índice de gema, gravidade e UH foram melhores no tratamento com utilização de óleo de girassol. Houve efeito residual da utilização de fontes lipídicas de origem vegetal na dieta em fase de recria de codornas japonesas sobre as características da qualidade dos ovos. As fontes lipídicas oriundas das sementes de soja, milho, algodão, canola e girassol podem ser utilizadas como ingredientes energéticos na dieta de recria de codornas poedeiras por nâo serem prejudiciais ao desempenho inicial das aves. A longevidade na produção dos ovos das aves alimentadas com diferentes fontes lipídicas na fase de recria foi semelhante.

ABSTRACT Purpose: The aim of this randomized study was to compare the complications and perioperative outcome of three different techniques of laparoscopic cholecystectomy (LC). Changes in the liver function test after LC techniques were investigated. Also, we compared the degree of postoperative adhesions and histopathological changes of the liver bed. Methods: Thirty rabbits were divided into three groups: group A) Fundus-first technique by Hook dissecting instrument and Roeder Slipknot applied for cystic duct (CD) ligation; group B) conventional technique by Maryland dissecting forceps and electrothermal bipolar vessel sealing (EBVS) for CD seal; group C) conventional technique by EBVS for gallbladder (GB) dissection and CD seal. Results: Group A presented a longer GB dissection time than groups B and C. GB perforation and bleeding from tissues adjacent to GB were similar among tested groups. Gamma-glutamyl transferase and alkaline phosphatase levels increased (p ≤ 0.05) on day 3 postoperatively in group A. By the 15th postoperative day, the enzymes returned to the preoperative values. Transient elevation of hepatic transaminases occurred after LC in all groups. Group A had a higher adherence score than groups B and C and was associated with the least predictable technique. Conclusions: LC can be performed using different techniques, although the use of EBVS is highly recommended.

Abstract Introduction: Sensitization to human leukocyte antigen is a barrier to. Few data have been published on desensitization using polyvalent human intravenous immunoglobulin (IVIG) alone. Methods: We retrospectively reviewed the of 45 patients with a positive complement-dependent cytotoxicity crossmatch (CDCXM) or flow cytometry crossmatch (FCXM) against living donors from January 2003 to December 2014. Of these, 12 were excluded. Patients received monthly IVIG infusions (2 g/kg) only until they had a negative T-cell and B-cell FCXM. Results: During the 33 patients, 22 (66.7%) underwent living donor kidney transplantation, 7 (21.2%) received a deceased donor graft, and 4 (12.1%) did not undergo transplantation. The median class I and II panel reactive antibodies for these patients were 80.5% (range 61%-95%) and 83.0% (range 42%-94%), respectively. Patients (81.8%) had a positive T-cell and/or B-cell CDCXM and 4 (18.2%) had a positive T-cell and/or B-cell FCXM. Patients underwent transplantation after a median of 6 (range 3-16). The median donor-specific antibody mean fluorescence intensity sum was 5057 (range 2246-11,691) before and 1389 (range 934-2492) after desensitization (p = 0.0001). Mean patient follow-up time after transplantation was 60.5 (SD, 36.8) months. Nine patients (45.0%). Death-censored graft survival at 1, 3, and 5 years after transplant was 86.4, 86.4, and 79.2%, respectively and patient survival was 95.5, 95.5, and 83.7%, respectively. Conclusions: Desensitization using IVIG alone is an effective strategy, allowing successful transplantation in 87.9% of these highly sensitized patients.

Resumo Introdução: Sensibilização HLA é uma barreira ao transplante em pacientes sensibilizados. Há poucos dados publicados sobre dessensibilização utilizando somente imunoglobulina intravenosa humana polivalente (IgIV). Métodos: Revisamos retrospectivamente prontuários de 45 pacientes com prova cruzada positiva por citotoxicidade dependente do complemento (CDCXM) ou citometria de fluxo (FCXM) contra doadores vivos, de Janeiro/2003-Dezembro/2014. Destes, excluímos 12. 33 pacientes receberam infusões mensais de IgIV (2 g/kg) apenas até apresentarem FCXM células T e B negativa. Resultados: Durante dessensibilização, 22 pacientes (66,7%) realizaram transplante renal com doador vivo, 7 (21,2%) receberam enxerto de doador falecido, 4 (12,1%) não realizaram transplante. A mediana do painel de reatividade de anticorpos classes I e II para estes pacientes foi 80,5% (intervalo 61%-95%) e 83,0% (intervalo 42%-94%), respectivamente. 18 pacientes (81,8%) apresentaram CDCXM célula T e/ou B positiva; 4 (18,2%) apresentaram FCXM célula T e/ou B positiva. Pacientes realizaram transplante após mediana de 6 (intervalo 3-16) infusões. A mediana da somatória da intensidade média de fluorescência do anticorpo específico contra o doador foi 5057 (intervalo 2246-11.691) antes e 1389 (intervalo 934-2492) após dessensibilização (p = 0,0001). O tempo médio de acompanhamento do paciente pós transplante foi 60,5 (DP, 36,8) meses. Nove pacientes (45,0%) não apresentaram rejeição e 6 (27,3%) apresentaram rejeição mediada por anticorpos. Sobrevida do enxerto censurada para óbito em 1, 3, 5 anos após transplante foi 86,4; 86,4; 79,2%, respectivamente, e sobrevida do paciente foi 95,5; 95,5; 83,7%, respectivamente. Conclusões: Dessensibilização utilizando apenas IgIV é uma estratégia eficaz, permitindo transplante bem-sucedido em 87,9% destes pacientes altamente sensibilizados.

Resumen Este artículo aborda la problemática de la alfabetización digital e informacional, relacionándola con la relevancia de la gobernanza electrónica y el impacto que esta tiene en las personas mayores. Para ello, se utilizó un enfoque cualitativo–descriptivo para el análisis de los datos sobre el impacto del programa. Como instrumento de análisis se optó por la noción y método de agencia personal, que da prioridad a la libertad, el cumplimiento de metas y el desarrollo de valores personales transcendentes para el individuo. Entre los principales resultados obtenidos se destacan los logros alcanzados por las personas mayores en autoeficacia, autodeterminación, control de sus conductas, reconocimiento de su aprendizaje y empoderamiento. Entre las principales conclusiones se destacan que por medio de un programa enfocado en las personas mayores se logra disminuir la brecha digital, destacándose la importancia de la autonomía e independencia respecto de su entorno, el autoaprendizaje y el aprender haciendo, como competencias fundamentales para sociedad actual.

Abstract This article addresses the problem of digital and information literacy, relating it to the relevance of electronic governance and the impact it has on the elderly. For this, a qualitative-descriptive approach was used to analyze the data on the impact of the program. As an instrument of analysis, the notion and method of personal agency was chosen, which gives priority to freedom, the fulfillment of goals and the development of transcendent personal values for the individual. Among the main results obtained, the achievements made by older people in self-efficacy, self-determination, control of their behavior, recognition of their learning and empowerment stand out. Among the main conclusions, it is highlighted that through a program focused on the elderly, the digital gap is reduced, highlighting the importance of autonomy and independence with respect to their environment, self-learning and learning by doing, as fundamental skills for today´s society.

Resumen Introducción: la capilaroscopia es un método no invasivo que permite observar la microvasculatura en el área periungueal. Los resultados informados pueden ser altamente variables entre distintos observadores. A lo largo del tiempo surgieron métodos cuantitativos y semicuantitativos para mejorar la reproducibilidad. Objetivos: conocer el nivel de acuerdo intra e interobservador al informar los diferentes patrones capilaroscópicos en individuos con diferente nivel de entrenamiento. Materiales y métodos: estudio de corte transversal. Participaron médicos reumatólogos especialistas y en formación que habían realizado previamente un curso virtual de capacitación en capilaroscopia. Recibieron 40 imágenes capilaroscópicas proyectadas en una presentación de PowerPoint y debían responder a través de un cuestionario digital. Se evaluó la concordancia de respuestas intra e interobservador. Resultados: se encontró un alto nivel de concordancia global con un kappa 0,66 IC 95% (0,63-0,70) p<0,0000. También en otros grupos como reumatólogos en formación: kappa 0,65 IC 95% (0,60-0,71) p=0,0000, y médicos reumatólogos: kappa 0,67 IC 95% (0,62-0,72) p=0,0000. Conclusiones: el nivel de concordancia encontrado fue globalmente alto, independientemente del nivel de entrenamiento de los profesionales, y de ser o no reumatólogo. La concordancia fue superior cuando se comparó a quienes tenían más de 4 años de experiencia en la realización de videocapilaroscopia.

Abstract Introduction: videoapillaroscopy is a non-invasive method that allows the observation of the microvasculature in the periungual area. Reported results can be highly variable between different observers. Over time, quantitative and semi-quantitative methods emerged to improve reproducibility. Objetives: to know the level of intra and interobserver agreement when reporting the different capillaroscopic patterns in individuals with different levels of training. Materials and methods: cross section study. Specialist rheumatologists and those in training who had previously completed a virtual capillaroscopy training course participated. They received 40 capillaroscopic images projected in a PowerPoint presentation and had to issue their response through a digital questionnaire. Concordance of intra and interobserver responses was evaluated. Results: a high level of global agreement was found with a kappa 0.66 CI 95% (0.63-0.70) p<0.0000, also in other groups such as rheumatologists in training: kappa 0.65 CI 95% (0.60-0.71) p=0.0000, physicians rheumatologists: kappa 0.67 95% CI (0.62-0.72) p=0.0000. Conclusions: the level of agreement found was globally high, regardless of the level of training of the professionals, and whether or not they were a rheumatologist. Concordance was higher when compared to those who had more than 4 years of experience performing videocapillaroscopy.
