Anatomy of the splenic artery: what does the surgeon need to know?

OBJECTIVE: to determine the prevalence and describe the main morphological and metric variations of the splenic artery in terms of its origin, path and polar and terminal branches. METHODS: cross-sectional study, carried out at Hospital de Clínicas between July and November 2020. Computed tomography scans were analyzed with intravenous contrast of the patients seen at the Radiology and Diagnostic Imaging Service. The findings were categorized as to origin, path and splenic ramifications. RESULTS: 1,235 patients were evaluated. As for the origin, the splenic artery appears in the celiac trunk in 99.11% of the individuals. Of these, 5.95% have a bifurcated celiac pattern, 92.17% trifurcated and 1.88% tetrafurcated. The mean arterial diameter was 5.92mm (±1.2), the highest one being in white men. As for the path, the splenic artery was unique in the entire sample. The suprapancreatic course was found in 75.63% of the individuals, with a higher occurrence in women, 78.87% (p<0.001). The terminal splitting pattern of the splenic artery was characterized by the bifurcated type (95.47%). The terminal branches seen most frequently were those with three arteries (34.90%) and most individuals did not have polar branches. CONCLUSION: the splenic artery presents a highly variable pattern of origin and its average caliber is influenced by sex and color. The suprapancreatic path was the most characteristic and predominant in females. The bifurcated pattern of final division, with three terminal branches and the absence of polar arteries, occurs more frequently.

First molecular detection of canine herpesvirus 1 (CaHV-1) in the Eastern Brazilian Amazon

Background@#Canine herpesvirus type 1 (CaHV-1) infects dogs and is associated with neonatal deaths and reproductive, ocular, neurological, and respiratory problems. In Brazil, reports of CaHV-1 have been restricted to the southeast and south regions, particularly in municipalities in the state of Rio Grande do Sul. @*Objectives@#To assess the presence and variability of CaHV-1 in canine populations in the state of Pará, North Brazil. @*Methods@#Biological samples from 159 dogs from 4 municipalities in the State of Pará were evaluated using polymerase chain reaction and phylogenetic analyses, with the target being the viral enzyme, thymidine kinase. @*Results@#CaHV-1 was detected in 13 dogs (8.2%), with 2 animals being from the municipality of Santa Bárbara do Pará, 8 from Algodoal Island, 2 from Salinópolis, and one from Capanema. The study sequences revealed 100% identity among themselves and 64% to 100% identity with the other nucleotide sequences from Australia, Brazil, United Kingdom, and United States, including 100% identity with the 2002 isolate from Australia. The 1996 isolate from France was grouped in a branch that was different from the sequence of this study. @*Conclusions@#This study presents the first molecular detection of CaHV-1 in dogs from the Amazon region in northern Brazil. The nucleotide identity between the strains and cytosine insertion in the sequences isolated in this study suggests at least 2 strains of CaHV-1 circulating in Brazil (Pará and BTU-1).

RESUMO Objetivo: determinar a prevalência e descrever as principais variações morfológicas e métricas da artéria esplênica quanto a sua origem, trajeto e ramos terminais e polares. Métodos: estudo transversal, realizado no Hospital de Clínicas entre julho e novembro de 2020. Foram analisadas tomografias computadorizadas com contraste endovenoso dos pacientes atendidos no Serviço de Radiologia e Diagnóstico por Imagem. Os achados foram categorizados quanto à origem, trajeto e ramificações esplênicas. Resultados: foram avaliados 1.235 pacientes. Quanto à origem, a artéria esplênica surge no tronco celíaco em 99,11% dos indivíduos. Desses, 5,95% apresentam padrão celíaco bifurcado, 92,17% trifurcado e 1,88% tetrafurcado. O diâmetro arterial médio foi de 5,92mm (±1,2), sendo a maior média em homens brancos. Quanto ao trajeto, a artéria esplênica se apresentou única em toda a amostra. O curso suprapancreático esteve em 75,63% dos indivíduos, com maior ocorrência em mulheres 78,87% (p<0,001). O padrão de divisão terminal da artéria esplênica caracterizou-se pelo tipo bifurcado (95,47%). Os ramos terminais visualizados mais frequentemente foram os com três artérias (34,90%) e a maioria dos indivíduos não apresentou ramos polares. Conclusão: a artéria esplênica apresenta padrão de origem altamente variável e seu calibre médio é influenciado por sexo e cor. O trajeto suprapancreático foi o mais característico e predominou no sexo feminino. O padrão bifurcado de divisão final, com três ramos terminais e ausência de artérias polares, ocorre com maior frequência.

Cardiac parameters and endothelial function in a strength athlete: a case report

We aimed to discuss a case of strength training athlete who competes in international competitions regarding cardiac (dimension and function), vascular (endothelium and vascular resistance), hemodynamic (blood pressure), given limited evidence supporting these cardiovascular adaptations as well as concerning endothelial function in long-term high-intensity strength training. Methods: We assessed heart structure and function (echocardiography); systolic (SBP) and diastolic blood pressure (DBP); endothelium-dependent vasodilation (flow-mediated dilation, FMD); maximum force tested in the squat, bench press, and deadlift; and maximum oxygen consumption (spirometry). Results: powerlifter's cardiac dimensions (interventricular septum 13 mm; posterior wall thickness 12 mm; LV diastolic diameter 57 mm; left ventricle mass 383 g; LV mass adjusted by body surface area 151.4 g/m2) are above the proposed cutoff values beyond which pathology may be considered. Moreover, cardiovascular function systolic (ejection fraction by Simpson's rule, 71%) is preserved and FMD measure is fairly close and above normal; however, a mild increase in systolic and diastolic blood pressure was observed (130/89 mmHg, respectively). Conclusion: Cardiac remodeling cannot be viewed as either pathological or harmful to the cardiovascular system. Furthermore, we showed an improvement in endothelial function.(AU)

Impact of Different Normality Thresholds for 24-hour ABPM at the Primary Health Care Level / Impacto de Diferentes Limiares de Normalidade para a MAPA de 24 Horas no Nível de Atenção Primária à Saúde

Abstract Background: Hypertension is an important risk factor for cardiovascular outcomes. Primary health care (PHC) physicians should be prepared to act appropriately in the prevention of cardiovascular risk factors. However, the rates of patients with control of blood pressure (BP) remain low. The impact of the reclassification of high BP by 24-hour ambulatory BP monitoring (ABPM) can lead to different medical decisions in PHC. Objective: To evaluate the agreement between the BP measured by a conventional method by PHC physicians and by 24-hour ABPM, considering different BP normal thresholds for the 24-hour ABPM according to the V Brazilian ABPM Guidelines and the European Society of Hypertension Guidelines. Methods: A cross-sectional study including 569 hypertensive patients. The BP was initially measured by the PHC physicians and, later, by 24-hour ABPM. The BP measurements were obtained independently between the two methods. The therapeutic targets for the conventional BP followed the guidelines by the Eighth Joint National Committee (JNC 8), the V ABPM Brazilian Guidelines, and the 2013 European Hypertension Guidelines. Results: There was an accuracy of 54.8% (95% confidence interval [95%CI] 0.51 - 0.58%) for the BP measured with the conventional method when compared with the 24-hour ABPM, with a sensitivity of 85% (95%CI 80.8 - 88.6%), specificity of 31.9% (95%CI 28.7 - 34.7%), and kappa value of 0.155, when considering the European Hypertension Guidelines. When using more stringent thresholds to characterize the BP as "normal" by ABPM, the accuracy was 45% (95%CI 0.41 - 0.47%) for conventional measurement when compared with 24-hour ABPM, with a sensitivity of 86.7% (95%CI 0.81 - 0.91%), specificity of 29% (95%CI 0.26 - 0.30%), and kappa value of 0.103. Conclusion: The BP measurements obtained by PHC physicians showed low accuracy when compared with those obtained by 24-hour ABPM, regardless of the threshold set by the different guidelines.

Resumo Fundamentos: A hipertensão arterial sistêmica é um fator de risco importante para desfechos cardiovasculares. Médicos da atenção primária à saúde (APS) devem estar preparados para atuar adequadamente na prevenção de fatores de risco cardiovascular. No entanto, as taxas de pacientes com pressão arterial (PA) controlada continuam baixas. O impacto da reclassificação do diagnóstico de hipertensão pela utilização da monitorização ambulatorial da PA (MAPA) de 24 horas pode levar a diferentes decisões médicas na APS. Objetivo: Avaliar a concordância entre as PAs medidas por método convencional por médicos da APS e por MAPA de 24 horas, considerando diferentes limiares de normalidade para a MAPA de 24 horas de acordo com as recomendações da V Diretriz Brasileira de MAPA e da Diretriz da Sociedade Europeia de Hipertensão. Métodos: Estudo transversal com 569 pacientes hipertensos. A PA foi medida inicialmente por médicos da APS e, posteriormente, pela MAPA de 24 horas. As medidas foram obtidas de forma independente entre os dois métodos. Os alvos terapêuticos para a PA convencional seguiram as orientações do Eighth Joint National Committee (JNC 8), das V Diretrizes Brasileiras de MAPA e das Diretrizes Europeias de Hipertensão de 2013. Resultados: Foi observada uma acurácia de 54,8% (intervalo de confiança de 95% [IC95%] 0,51 - 0,58%) para a PA aferida de forma convencional quando comparada à obtida com a MAPA de 24 horas, além de uma sensibilidade de 85% (IC95% 80,8 - 88,6%), especificidade de 31,9% (IC95% 28,7 - 34,7%) e kappa de 0,155, quando consideradas as Diretrizes Europeias de Hipertensão. Quando utilizados limiares mais rígidos para caracterizar a PA como "normal" pela MAPA, foi identificada uma acurácia de 45% (IC95% 0,41 - 0,47%) pela medida convencional quando comparada à obtida pela MAPA de 24 horas, além de uma sensibilidade de 86,7% (IC95% 0,81 - 0,91%), especificidade de 29% (IC95% 0,26 - 0,30%) e kappa de 0,103. Conclusão: As medidas de PA avaliadas pelos médicos da APS apresentaram baixa acurácia quando comparadas às medidas pela MAPA de 24 horas, independente do limiar utilizado pelas diferentes diretrizes.

Serum C-reactive protein levels and body mass index in children and adolescents with CHD.

BACKGROUND: The prevalence of overweight in children with CHD is about 26.9%. Increase in adipose tissue is related to the secretion of proinflammatory markers such as C-reactive protein. Assuming that children with CHD are exposed to other inherent risk factors for heart disease, our objective was to evaluate the correlation between levels of C-reactive protein and body mass index in children and adolescents with CHD. METHODS: A cross-sectional study with 377 children and adolescents with CHD in a clinical setting of a reference hospital was carried out. C-reactive protein data were collected after 12 hours of fasting. Nutritional status was classified according to body mass index. The patients were divided into three groups: cyanotic, acyanotic, and minimal heart defects (controls). RESULTS: The mean age was 9.9±4.2 years, and 53.6% of the sample included males. The cyanotic group represented 22.3%, acyanotic 42.2%, and minimal defects 35.5% of the sample. The average body mass index percentile was 57.23±32.06. The median values of C-reactive protein were as follows: cyanotic 0.340, acyanotic with clinical repercussion 0.203, and minimal defects 0.128. There was a significant difference between the minimal defects and the cyanotic groups (p=0.023). There was a significant correlation between C-reactive protein and body mass index percentile (r=0.293, p<0.01). C-reactive protein levels were higher in girls (p=0.034). There were no significant correlations between C-reactive protein and age or birth weight. CONCLUSION: The correlation between body mass index percentile and C-reactive protein was confirmed in this population. The prevention of overweight is paramount to avoid overlapping modifiable risk factors to those already inherent to the CHD.

Interest in research among medical students: Challenges for the undergraduate education.

INTRODUCTION:: In recent decades, there has been a reduction in the number of graduates from medical schools who choose to pursue a career in scientific research. That has an impact on the profile of graduates, since medical education depends on understanding the formation of scientific evidence. The construction of new knowledge is also hampered by the reduction of medical scientists, whose clinical experience with patients provides an essential step towards medical Science evolution. OBJECTIVE:: The present cross-sectional study sought to identify the interest in research among medical students from a federal university in southern Brazil. METHOD:: Medical students from a federal university were asked to respond to a self-administered questionnaire that sought to identify the level of knowledge about the importance of scientific research in medical training, and the interest of this population in this element of their training. RESULTS:: 278 medical students from the first to the sixth year responded to the questionnaire, and 81.7% stated their interest in medical research. However, only 4.7% of respondents considered research as first in degree of importance to their medical training. The variable "interest in research" showed no statistically significant association with age, gender, presence of physicians in the family, or other prior college courses. CONCLUSION:: Although interest in research is clearly present among the students, this is still an underexplored element among the population studied. The incorporation of research in the learning process depends on stimulus and guidance until it becomes culturally consolidated as an essential element of the medical training.

Resumo Introdução: nas últimas décadas, diminuiu o número de egressos de escolas médicas que optam por se dedicar à pesquisa científica. Isso tem impacto sobre o perfil dos profissionais formados, já que o aprendizado médico é indissociável da compreensão da formação da evidência científica. A formação de novo conhecimento é prejudicada com a redução de pesquisadores médicos, cujo contato clínico com os pacientes fornece etapa essencial na evolução da ciência médica. Objetivo: o presente estudo transversal buscou identificar o interesse em pesquisa entre estudantes de medicina de uma universidade federal do Sul do Brasil. Método: estudantes de medicina de uma universidade federal foram convidados a responder um questionário autoaplicável que buscou identificar o nível de conhecimento sobre a importância da pesquisa científica na formação do médico, bem como o interesse dessa população por esse elemento da formação. Resultados: 278 estudantes de todas as séries do curso de medicina responderam ao questionário, e 81,7% declararam interesse pela pesquisa científica. Contudo, apenas 4,7% dos entrevistados consideraram a pesquisa em primeiro lugar em grau de importância para a sua formação. A variável "interesse em pesquisa" não apresentou associação estatisticamente significativa com idade, gênero, presença de médicos na família ou outro curso superior prévio. Conclusão: embora o interesse em pesquisa esteja claramente presente entre os estudantes, este é um elemento da formação ainda pouco explorado pela população estudada. A incorporação da pesquisa na rotina do aprendizado depende de estímulo e orientação até que esteja culturalmente consolidada como matriz essencial da formação.

Carpal tunnel syndrome: mobilization and segmental stabilization / Mobilização neural e estabilização segmentar na síndrome do túnel do carpo

Abstract Introduction: Carpal tunnel syndrome is a compressive neuropathy, frequently seen in women. Conservative treatment for carpal tunnel syndrome focuses on control of symptoms and the nervous path, due to the possibility of double compression. Objective: To assess whether a protocol with emphasis on motor control techniques, including segmental cervical stabilization and neural mobilization, has better results in mechanical reorganization and reduction of symptoms when compared with classic therapeutic exercise techniques in the conservative treatment of carpal tunnel syndrome. Methods: This pilot study was a randomized, double-blind clinical trial, involving 11 women with an average age of 54 (± 6) years, allocated to either a classical kinesiotherapy group (CG) or experimental group (EG). The intervention spanned 12 weeks, with assessments prior to and following therapy, using the monofilament test, handgrip dynamometer, and BCTQ, DASH, and PRWE questionnaires. All normally distributed data was analysed with Student's T-tests. Results: Both groups exhibited an increase in grip strength and relief of symptoms with improved functionality. There was a significant reduction in sensitivity noted in the CG group, and a significant increase in grip strength observed in the EG group. Conclusion: The experimental protocol group exhibited better results in mechanical reorganization, reflected in increased strength, sensitivity, and improved functionality, when compared to the group with conventional therapeutic exercise, but without the same symptomatic reduction.

Resumo Introdução: Compreende a Síndrome do Túnel do Carpo (STC) uma neuropatia compressiva frequente em mulheres. No tratamento conservador, a ênfase é dada ao controle da sintomatologia e ao trajeto nervoso devido à hipótese de dupla compressão. Objetivo: Avaliar se um protocolo com ênfase nas técnicas de controle motor, constituído por estabilização segmentar cervical e mobilização neural, apresentam melhores resultados na reorganização mecânica e redução dos sintomas quando comparado com técnicas de cinesioterapia clássica. Métodos: Estudo piloto de um ensaio clínico randomizado duplo cego, em 11 mulheres, alocadas em Grupo Cinesioterapia clássica (GC), e Grupo Experimental (GE). A intervenção foi de 12 semanas, com avaliações no pré e pós, por meio da estesiometria, dinamometria de preensão palmar e aplicação dos questionários BCTQ, DASH e PRWE. Resultados: Ambos aumentaram a força de pinça com alívio da sintomatologia e melhora da funcionalidade. Houve diminuição da sensibilidade no GC e aumento significativo da força de preensão palmar no GE. Conclusão: O grupo do protocolo proposto apresentou melhores resultados na reorganização mecânica, com reflexo no aumento da força, da sensibilidade e melhora da funcionalidade, quando confrontado ao grupo com cinesioterapia convencional, porém sem o mesmo impacto para a redução dos sintomas.

Resilience in Patients with Ischemic Heart Disease / Resiliência em Pacientes Portadores de Cardiopatia Isquêmica

Background: Resilience is a psychosocial factor associated with clinical outcomes in chronic diseases. The relationship between this protective factor and certain diseases, such heart diseases, is still under-explored. Objective: The present study sought to investigate the frequency of resilience in individuals with ischemic heart disease. Method: This was a cross-sectional study with 133 patients of both genders, aged between 35 and 65 years, treated at Rio Grande do Sul Cardiology Institute - Cardiology University Foundation, with a diagnosis of ischemic heart disease during the study period. Sixty-seven patients had a history of acute myocardial infarction. The individuals were interviewed and evaluated by the Wagnild & Young resilience scale and a sociodemographic questionnaire. Results: Eighty-one percent of patients were classified as resilient according to the scale. Conclusion: In the sample studied, resilience was identified in high proportion among patients with ischemic heart disease.

Fundamento: A resiliência é um fator psicossocial associado a desfechos clínicos em doenças crônicas. A relação entre este fator protetor e determinadas doenças, como cardiopatia s, ainda é pouco explorada. Objetivos: O presente estudo buscou investigar a frequência da resiliência em indivíduos portadores de cardiopatia isquêmica. Método: Este foi um estudo transversal com 133 pacientes entre 35 e 65 anos, de ambos os gêneros, atendidos no Instituto de Cardiologia do Rio Grande do Sul - Fundação Universitária de Cardiologia, com diagnóstico de cardiopatia isquêmica durante o período do estudo. Destes, 67 já haviam apresentado pelo menos um episódio de infarto agudo do miocárdio. Os indivíduos foram entrevistados e avaliados pela Escala de Avaliação de Resiliência desenvolvida por Wagnild & Young e por uma ficha de questionário sociodemográfico. Resultados: Do total de pacientes, 81% foram classificados como resilientes de acordo com a escala. Conclusão: Na amostra estudada, a resiliência foi identificada em elevada proporção na população de pacientes com cardiopatia isquêmica.

Resilience in Patients with Ischemic Heart Disease.

BACKGROUND: Resilience is a psychosocial factor associated with clinical outcomes in chronic diseases. The relationship between this protective factor and certain diseases, such heart diseases, is still under-explored. OBJECTIVE: The present study sought to investigate the frequency of resilience in individuals with ischemic heart disease. METHOD: This was a cross-sectional study with 133 patients of both genders, aged between 35 and 65 years, treated at Rio Grande do Sul Cardiology Institute - Cardiology University Foundation, with a diagnosis of ischemic heart disease during the study period. Sixty-seven patients had a history of acute myocardial infarction. The individuals were interviewed and evaluated by the Wagnild & Young resilience scale and a sociodemographic questionnaire. RESULTS: Eighty-one percent of patients were classified as resilient according to the scale. CONCLUSION: In the sample studied, resilience was identified in high proportion among patients with ischemic heart disease.

Fratura mandibular atípica por arma branca: relato de caso / Atypical mandibular fracture by lethal weapon: a case report

Lesões em face causadas por armas brancas, são pouco citadas na literatura, na maioria das vezes com relatos de casos. O cirurgião Buco- Maxilo-Facial, entretanto, deve estar apto a lidar com tal ocorrência, haja vista a significância estético-funcional dessa área. Como forma de contribuir com a referida temática, este trabalho tem por objetivo apresentar e discutir detalhes das técnicas bem como cuidados para prevenir possíveis complicações de um paciente apresentando múltiplos ferimentos corto contusos em região de mento e de traqueia, associados à fratura de sínfise e corpo mandibulares...

Docinhos e ensaios de não inferioridade: uma experiência pedagógica criativa / Candies in the study of non-inferiority trials: a creative pedagogic experiment

Os novos desafios na área da educação surgem com o próprio desenvolvimento do conhecimento. Novas técnicas de pesquisa possibilitaram grandes descobertas na ciência e, com isso, uma crescente complexificação dos temas estudados. Os alunos, inseridos no universo dinâmico da internet, também evoluíram e não se encaixam mais nas prescrições da pedagogia tradicional. Para essas novas realidades, a forma de educar no século XXI exige dos educadores um esforço de criatividade para transmitir um conhecimento cada vez mais complexo. Para ilustrar essa nova situação, relatamos uma experiência pedagógica que buscou, com a criatividade de uma intervenção fictícia, favorecer o ensino dos ensaios clínicos de não inferioridade. A experiência demonstra a utilidade de tais ensaios clínicos quando se necessita testar a eficácia de tratamentos. A utilização dos docinhos e a participação dos alunos como sujeitos do ensaio configuraram-se como uma metodologia ativa, de aproximação entre os educandos e seu objeto de estudo. O exercício realizado está de acordo com os modelos pedagógicos sugeridos pela teoria da aprendizagem significativa e pode servir de referência para iniciativas semelhantes.

New challenges in education parallel with knowledge expansion. New research techniques have enabled major discoveries in science, together with a growing complexity of the studied themes. Students, part of the dynamic universe of the Internet, have also evolved and no longer fit the requirements of traditional pedagogy. For these new realities the way to educate in the twenty-first century requires a creative effort from educators, in order to convey knowledge that is increasingly complex. As an illustration of this new situation, we bring the report of a pedagogical experiment that sought, with the creativity of a fictitious intervention, to support the teaching of non-inferiority clinical trials. The experiment managed to show the usefulness of such clinical trials when there is the need to test the efficacy of treatments. The use of sweets and the participation of students as the test subjects constitute an active methodology, bringing students closer to their subject of study. The exercise conducted is in line with the pedagogical models suggested by the meaningful learning theory and can be used as a benchmark for similar initiatives.
