Reprodução equina: um modelo de ensino / Equine reproduction: a teaching model

Vivemos nos últimos anos um momento difícil em relação ao ensino de qualidade na medicina veterinária brasileira. Por sua vez, a equideocultura brasileira possui destaque internacional pela alta demanda de empregabilidade e pela excelência de seu plantel. Sempre a frente do seu tempo, a Pontifícia Universidade Católica do Paraná, a PUCPR, possui um curso de 28 anos de história, onde a excelência no ensino é reconhecida de norte a sul do país. Ao longo dessa história, um dos grandes diferenciais da universidade são os grupos de estudos, que são realizados por áreas específicas no curso e que acontecem no contraturno do estudante. Um dos primeiros grupos de estudos formados na PUCPR, foi em 2003: o Grupo de Estudos em Reprodução Animal. E com um grande interesse dos estudantes pela área de equinos, em 2008 nasce o Grupo de Estudos em Reprodução de Equídeos que perdura até os dias de hoje com o nome de Liga Acadêmica em Reprodução de Equídeos lado a lado da Liga Acadêmica de Reprodução de Bovinos. Desde então, na área da reprodução equina, um trabalho realizado com os estudantes que simula a vida real de um haras de criação e um centro de reprodução equina junto ao rebanho didático da instituição. O que torna esse modelo de ensino da PUCPR especial é como ele é conduzido, levando o estudante através de trilhas ao longo da graduação que permite que ele realmente se forme podendo trabalhar e exercer na plenitude a reprodução equina. Ao longo de 23 anos, se observa que os profissionais ligados a reprodução equina e bovina, egressos do curso de medicina veterinária da PUCPR são referências em renomados criatórios de equinos no Brasil. Com todo esse trabalho desenvolvido ao longo dos 5 anos com esses estudantes temos a tranquilidade e a satisfação de entregar a sociedade profissionais extremamente capacitados, e prontos para o mercado do cavalo, de forma ética e respeitando os cavalos e todas as formas de bem-estar animal.(AU)

In recent years, we have experienced a difficult time in relation to quality teaching in Brazilian veterinary medicine. On the other hand, the Brazilian equideoculture has international prominence due to the high demand for employability and the excellence of its herd. Always ahead of its time, the Pontifical Catholic University of Paraná, PUCPR, has a course of 28 years of history, where excellence in teaching is recognized from north to south of the country. Throughout this history, one of the great differentials of the university are the study groups, which are carried out by specific areas in the course, and which take place in the student's after-school period. One of the first study groups formed at PUCPR was in 2003: the Animal Reproduction Study Group. And with a great interest of students in the equine area, in 2008 the Equine Reproduction Study Group was born, which lasts until today under the name of Academic League in Equine Reproduction side by side with the Academic League of Bovine Reproduction. Since then, around equine reproduction, work has been carried out with students that simulates the real life of a stud farm and an equine reproduction center with the institution's didactic herd. What makes this PUCPR teaching model special is how it is conducted, taking the student through paths throughout graduation that allow him to really graduate, being able to work and fully exercise equine reproduction. Over 23 years, it has been observed that professionals linked to equine and bovine reproduction, graduates of the PUCPR Veterinary Medicine course, are references in renowned equine breeding centers in Brazil. With all this work developed over the 5 years with these students, we have the tranquility and satisfaction of delivering extremely qualified professionals to society, ready for the horse market, ethically and respecting horses and all forms of welfare animal.(AU)

The trend towards evidence-based learning has led to the development of alternative teaching methods, where students with basic knowledge are led to learn the subject. In this way, it is possible to observe evolution in practical learning, theoretical growth in the area and more security in the execution of procedures. Through models made of different materials, such as plastics bottles, silicone models, students can practice techniques without the stress of a mistake putting the animal's life at risk, providing a more pleasant learning experience and safety to perform procedures on animals.(AU)

Colorações de malhas de sombreamento sobre a fenologia, biometria e características físico-químicas de Physalis peruviana L. em sistema orgânico de produção / Colors of shadowing meshes on phenology, biometrics and physicochemical characteristics of Physalis peruviana L. in organic production system

Objetivou-se neste trabalho verificar a influência de distintas colorações de malhas de sombreamento sobre a fenologia, biometria e características físico-químicas de Physalis peruviana L em sistema orgânico de produção. O experimento foi realizado na área experimentalda UFFS, campus Laranjeiras do Sul ­PR, no setor de Horticultura. Como material vegetal foram utilizadas mudas de P. peruviana L. produzidas em estufa agrícola da área didática experimental. O delineamento experimental foi em blocos completamente casualizados, em esquema unifatorial, com quatro malhas de sombreamento (azul, preta, vermelha e branca) + testemunha (sem cobertura), com quatro repetições. Para a fenologia não houve influência estatística das colorações de malhas de sombreamento. Plantas com maior altura e menordiâmetro de caule foram verificadas com o uso da malha de sombreamento da coloração azul. Houve alterações sobre a firmeza de frutos, massa com cálice, diâmetro, altura e sólidos solúveis em função da cor da malha de sombreamento. Conclui-se que as malhasde sombreamento de diferentes colorações não interferem na fenologia de P. peruviana, mas alteram ascaracterísticas biométricas e físico-químicas das frutas, sendo a de coloração vermelha a que proporcionou os melhores resultados, não sendo recomendada autilização da malha de coloração azul.(AU)

The objective of this work was to verify the influence of different colors of shading meshes onthe phenology, biometry and physicochemical characteristics of Physalis peruvianain an organic production system. The experiment was carried out in the experimental area of UFFS, campus Laranjeiras do Sul -PR, in the Horticulture sector. As plant material, seedlings of Physalis peruvianaL. produced in an agricultural greenhouse in the experimental teaching area were used. The experimental design was in completely randomized blocks, in a one-factor scheme, with four shading meshes (blue, black, red andwhite) + control (no cover), with four replications. For the phenology there was no statistical influence of the shading mesh colors. Plants with greater height and smaller diameter were verified using the blue color shading mesh. There were changes in fruit firmness, mass with calyx, diameter, height and soluble solids depending on the type of shading. It is concluded in this work that shading nets of different colors do not affect the phenology of the P. peruviana, but they change the biometric and physicochemical characteristics of fruits, with red color being the ones that provide the best results, the use of the blue colored mesh is not recommended.(AU)

Ten years of IRCAD, Barretos, SP, Brazil

Minimally invasive surgery represented a significant milestone in modern surgery; however, continuous innovation and the emergence of new technologies pose new challenges in terms of surgical learning curves since new interventions are associated with increased surgical complexity and a higher risk of complications.

Since its inauguration, in 2011, the center has already qualified numerous professionals and has placed the country in a privileged position in terms of surgical knowledge. The present article describes the activities developed over these ten years of the institute in Brazil as the largest training center for surgeons of the continent in order to address the importance of surgical skills training.

Causas da dificuldade de aprendizado na medicina veterinária entre os períodos matutino e noturno / Causes of learning difficulty in veterinary medicine between the morning and night periods / Causas de la dificultad de aprendizaje en medicina veterinaria entre los periodos de la mañana y la noche

Atualmente há diversas evoluções metodológicas de ensino. Assim, os cursos de Medicina Veterinária devem se adequar a formação curricular, tanto para o âmbito acadêmico quanto para preparação profissional, buscando novas possibilidades de ensino-aprendizagem centralizadas no discente, inclusive quando comparada a produtividade entre o período matutino e noturno. Com este propósito, foi desenvolvido um questionário, respondido de forma voluntária pelos alunos do curso de Medicina Veterinária, buscando analisar a importância e as dificuldades apresentadas por estes na disciplina de Biotecnologia da Reprodução Animal entre os períodos matutino e noturno. O questionário foi baseado no método observacional descritivo transversal, para coleta de dados foi utilizada a ferramenta online Google Formulários, possibilitando analisar limitações individuais, potenciais, experiências e expectativas sobre of conhecimento acadêmico entre os discentes. Concomitantemente, o questionário avaliou a realidade socioeconômica e cultural dos discentes. Através dos resultados foi possível concluir que alunos do período noturno, devido à realização de outras atividades durante o dia e fatores relacionados com a rotina apresentam maior estresse e cansaço. Tais fatores influenciam diretamente no desgaste fisico, psicológico e emocional dos discentes, do período noturno. Assim sendo, alunos de Medicina Veterinária do período noturno, na disciplina de Biotecnologia da Reprodução Animal, apresentam maiores dificuldades de assimilar conteúdo quando comparados aos alunos do período matutino.

There are currently several methodological developments in teaching. Thus, the Veterinary Medicine courses must adapt to the curricular formation, both for the academic scope and for professional preparation, seeking new possibilities of teaching-learning centered on the student, even when comparing the productivity between the morning and night shifts. With this purpose, a questionnaire was developed, answered voluntarily by students of the Veterinary Medicine course, seeking to analyze the importance and difficulties faced by them in the discipline of Animal Reproduction Biotechnology between the morning and night periods. The questionnaire was based on the transversal descriptive observational method, for data collection an online tool from Google Forms was used, enabling the analysis of individual limitations, potentials, experiences and expectations about academic knowledge among students. Concomitantly, the questionnaire assessed the socioeconomic and cultural reality of the students. Based on the results, it was possible to conclude that students from the night period, due to the performance of other activities during the day and factors related to their routine, present greater stress and fatigue. Such factors directly influence the physical, psychological and emotional wear of students at night. Therefore, night shift students of Veterinary Medicine, in the Animal Reproduction Biotechnology discipline, have greater difficulties in assimilating the content when compared to morning students.

Actualmente, existen varios avances metodológicos en la docencia. Así, los cursos de Medicina Veterinaria deben adaptarse a la formación curricular, tanto para el ámbito académico como para la preparación profesional, buscando nuevas posibilidades de enseñanza-aprendizaje centradas en el alumno, incluso al comparar la productividad entre los turnos matutino y nocturno. Con este propósito, se elaboró un cuestionario, respondido voluntariamente por los estudiantes del curso de Medicina Veterinaria, buscando analizar la importancia y dificultades que presentan en la disciplina de Biotecnología de la Reproducción Animal entre los períodos matutino y nocturno. El cuestionario se basó en el método observacional descriptivo transversal, para la recolección de datos se utilizó la herramienta en línea Google Forms, que permitió analizar las limitaciones, potenciales, experiencias y expectativas individuales sobre el conocimiento académico entre los estudiantes. Paralelamente, el cuestionario evaluó la realidad socioeconómica y cultural de los estudiantes. A través de los resultados se pudo concluir que los estudiantes del período nocturno, por realizar otras actividades durante el día y factores relacionados con su rutina, presentan mayor estrés y fatiga. Tales factores influyen directamente en el desgaste fisico, psicológico y emocional de los estudiantes durante la noche. Por tanto, los estudiantes del turno de noche de Medicina Veterinaria, en la disciplina de Biotecnología de la Reproducción Animal, tienen mayores dificultades para asimilar contenidos en comparación con los estudiantes de la mañana.

Conventional vs. advanced echocardiographic parameters for predicting fluid responsiveness in healthy dogs

Background: Volume replacement is considered an essential component in the treatment of critically ill patients, but excess f luid administration can be as harmful as the lack of fluid therapy. Therefore, the volume replacement is only beneficial in patients deemed to be fluid responsive, that is, when the individual has an increase in their stroke volume after administration of a volume challenge. This study aim to assess whether conventional and advanced echocardiographic parameters for assessing left ventricular systolic function are able to predict fluid responsiveness in healthy spontaneously breathing dogs. The hypothesis was that some of these parameters would differ between responsive and non-responsive animals and could be used as a complementary measure for assessment of fluid responsiveness. Materials, Methods & Results: A prospective study was carried out in which 22 client-owned healthy dogs over 1 year of age that presented to the Veterinary Medical Teaching Hospital for elective neutering procedure were included. All dogs underwent conventional and advanced echocardiographic examination to obtain the left ventricular internal diameter in diastole normalized (LVIDDn), left ventricular internal diameter in systole normalized (LVIDSn), ejection fraction (EF) and shortening fraction (SF) according to the Teischholz methodology, global longitudinal strain (GLS) and tissue motion annular displacement (TMAD). There parameters were evaluated before and after administration of a volume challenge with 10 mL/kg lactate ringer intravenously for 20 min. Based on the variation in aortic velocity integral time, 31.82% of dogs were considered responsive and 68.18% were non-responsive to the volume challenge. For advanced echocardiography, TMAD indexed by body weight (mm/kg) > 0.89 (P = 0.004) and body surface area (mm/m2) >18.9 (P = 0.004) after volume challenge had the best area...

Reconstrução prepucial com uso de enxerto combinado em cães / Preputial reconstruction combined with graft in dogs

Background: Preputial injuries are significant in the clinical routine. Traumas, conditions, and mass excision result in extensive and full-thickness defects that lead to chronic penile exposure and consequential injuries. Severe injuries may require preputial reconstructive surgery to restore function and aesthetics. The objective is to report the use of the preputial reconstruction technique using the caudal superficial epigastric axial standard flap associated with a single-stage, full-thickness oral mucosa graft in 3 dogs where the loss of the prepuce was significant. Cases: Three dogs were admitted to the Veterinary Teaching Hospital of UFMT with preputial lesions of different etiologies. All cases were referred for preventive reconstruction using a flap in the caudal axial epigastric pattern associated with a single-stage oral mucosa graft. In the 3 reported cases, changes that compromised surgical success, such as suture dehiscence, necrosis, or infection, were not observed during hospitalization. Cutaneous stitch dehiscence, however, was observed in all 3 cases. Dog 1. A small point of dehiscence and tissue necrosis was found and treated with chemical debridement and healed by second intention, which proved to be sufficient on the 30th day. Dog 2. A half-moon rotation flap was performed, which closed the defect. Dog 3. A new procedure using the reporting theme technique was necessary in order to cover the cranial portion of the foreskin. The dehiscence present in dogs 2 and 3 was significant. Flap retraction was observed in all 3 cases. In dogs 1 and 3, the retraction was slight, and the exposure of a small portion of the penile glans were observed, showing no changes that required intervention. In dog 2, retraction was important, leading to partial stenosis of the preputial ostium. A larger ostium was obtained by suturing the mucosa to the edge of the wedge. Considering the possibility of adhesion formation, "captons" were made in sterile silicone tubes, and sutures were placed in the dorsal and ventral aspects to prevent adherence of the oral mucosa graft located on the inside of the new foreskin. The captons were removed on the tenth post-operative day, revealing a good opening of the preputial orifice and adequate penile exposure. Discussion: The absence of a foreskin caused by trauma or surgical excision leads to chronic penile exposure, dryness, and ulcerations. The simple covering of the skin with an axial-type flap of the caudal superficial epigastric region tends to fail since only the graft edges are sutured into the abdominal skin. In these circumstances, the subcutaneous region on the penis is exposed and comes in direct contact with urine and the penile mucosa, causing the flap skin to grow to exacerbated retraction. The transplantation of a free-lip mucosa graft allows the subcutaneous region of the transposed skin flap to create adhesions in the fenestrated regions of the lip tissue through the formation of granulation tissue buds, which is performed in a single stage. The permanence of the penis protects the lower urinary system from the occurrence of infections relative to what is normally observed in cases where partial or total penile amputation is practiced in combination with adjunctive scrotal urethrostomy. Given the observations of the 3 cases described here, the technique of pre-facial reconstruction with an axial skin flap of the caudal superficial epigastric region, combined with free-labial mucosa graft, was found to be feasible for the single-stage foreskin technique, but that paraphimosis remanagement may be necessary when cutaneous portions of the penile skin caudal to the glans are removed.

Mastocitoma cutâneo em uma cadela / Cutaneous mast cell tumor in a bitch

Background: The diagnostic of neoplasia in dogs has risen significantly in the last years and this fact is mostly attributed to the longer life expectancy of these animals, which contributes to a greater chance of exposure to carcinogenic agents. In between the diverse tumors that could compromise skin, the mastocytoma is the third most commonly diagnosed neoplasia. It is characterized by being a form of neoplasia with round cells, these being the mast cells. The objective of the present study consisted in relating a case of cutaneous mastocytoma in a 7-year-old bitch mixed-breed treated at the Veterinary Medical Teaching Hospital of the University of Uberaba (UNIUBE) - Uberaba, MG, Brazil. Case: The bitch initially presented a localized nodule external to the right ear pinna with cytology test suggesting a mastocytoma. The nodule was surgically removed and, posteriorly, an histopatholgy was not requested. After 5 months since the emergence of the nodule and a month after its surgical resection, the tutor noticed the presence of a new growth in the ipsilateral cervical region to the previous nodule. At this moment, the responsible veterinarian decided to refer the animal to an oncologist. During the appointment with the oncologist, alterations such as hyporexia and anemia were related, and the presence of a nodule in the right cervical region measuring 4.5 to 4 cm of diameter was verified. Material for cytologic evaluation of the neoplasia was collected and again the result suggested a mastocytoma. The new tumor was also surgically removed but was then referred to histopathological evaluation for diagnostic confirmation, grading and evaluation of surgical margins. The tumor was classified as an infiltrative subcutaneous mastocytoma presenting, additionally, compromised surgical margins. After its excision, the association with a chemotherapy treatment using a protocol of Vimblastina 2 mg/m², i.v. in unique dosage per section, associated with Predinisona 1 mg/kg, v.o, SID was indicated. Each section was realized with an interval of 7 days in between. Only 2 chemotherapy sessions took place. Because of the worsening of the clinical condition associated with a very weakened animal the veterinarian opted for the euthanasia of the animal. Discussion: The diagnostic of mastocytoma must be realized through the association of cytology and histopathology, in case histopathological evaluation is needed to confirm the obtained cytology result, to grade the tumor and to evaluate the compromising of surgical margins. In this sense, it was observed that the bitch was submitted only to cytology diagnostic when it presented the nodule in the ear pavilion. Yet, at the second approach realized by the oncologist, it was possible to realize adequate diagnose methods. However, the animal was not submitted to clinical staging of the mastocytoma due to the non-authorization of the exam by the tutor. Such measure is very important, as it reflects directly in the treatment and prognostic of the animal. Thus, image exams such as abdominal ultrasonography and chest X-ray should have been realized, as well as cytological and histopathological evaluation of the regional lymph nodes, in order to search for metastasis points in these places. As the data suggests, the importance of clinical staging of animals affected by this neoplasia and the importance of cytological evaluation associated with histopathology for a correct diagnosis, prognosis and mastocytoma treatment is noted. It is emphasized that many times veterinarians face impediment related to requesting all necessary exams coming from tutors, which compromises treatment success.

An overweight/obesity survey among dogs and cats attended at a veterinary teaching hospital during the second year of the COVID-19 pandemic / Uma pesquisa sobre sobrepeso/obesidade em cães e gatos atendidos em um hospital veterinário escola durante o segundo ano de pandemia de COVID-19

Anecdotal reports suggest that the new coronavirus SARS-CoV-2 pandemic (COVID-19) has increased overweight and obesity prevalence in dogs and cats. The present report aimed to perform a retrospective overweight/obesity survey on 1,001 consecutive cases attended in the Veterinary Clinics Hospital from the Federal University of Rio Grande do Sul during its reopening to the public after months closed due to the pandemic. The overall overweight or obesity observed prevalence was 36.63%; being the frequency in cats slightly greater (38.37%) than compared to dogs (35.76%). No local increase in these frequencies was detected. Neutering (dogs and cats), age greater than 10 years (dogs), and male gender (cats) were factors associated with overweight/obesity. Bodyweight was not registered in about 30% of the medical records, while the body condition score was not registered in about 50% of the cases. These flaws were more often observed in feline medical records and efforts to improve these data records are warranted.

Especula-se que a pandemia pelo novo coronavirus SARS-CoV-2 (COVID-19) tenha agravado a prevalência de sobrepeso e obesidade em cães e gatos. O presente artigo teve como objetivo realizar um levantamento de sobrepeso/obesidade, o qual avaliou os registros de 1001 casos consecutivos atendidos no Hospital de Clínicas Veterinárias da Universidade Federal do Rio Grande do Sul, durante a reabertura da instituição ao público, após meses fechada devido à pandemia. Observou-se uma prevalência de sobrepeso ou de obesidade de 36,63%, sendo a frequência ligeiramente maior em gatos (38,37%) do que em cães (35,76%) e não sendo documentado aumento local na prevalência. Castrações (cães e gatos), idade > 10 anos (cães) e sexo masculino (gatos) foram associadas ao sobrepeso/obesidade. Em cerca de 30% das fichas não havia peso registrado, e em cerca de 50% não havia registro de ECC. Essas falhas foram mais frequentes em fichas de felinos e demandam medidas para aumentar o registro desses dados pelas equipes clínicas.

Pelve extrarrenal em uma gata - diagnóstico por cintilografia / Extrarenal pelvis in a cat - diagnosis by scintigraphy

Background: In people, extrarenal pelvis is a normal anatomical variant, characterized by the protusion of the pelvis out of the renal hilum, which can be associated with other anomalies, or predispose to stasis or infection. While other diagnostic imaging methods provide anatomical and morphological information about the kidney, scintigraphy allows to determine the renal function and has greater sensitivity in the detection of functional alterations. The aim of this work is to report the case of an asymptomatic cat diagnosed with extrarenal pelvis detected by scintigraphy, which presented alterations in laboratory and renal imaging tests, and absence of associated obstructive process. Case: A 7-year-old mixed-breed female cat was evaluated for a routine health assessment at the Veterinary Teaching Hospital of the Federal University of Rio Grande do Sul (HCV-UFRGS). When performing the imaging and laboratory tests, renal alterations compatible with chronic kidney disease were found in the abdominal ultrasonography examination and in serum creatinine levels. Therefore, it was decided to perform scintigraphy evaluation to better assess renal function. Dynamic renal scintigraphy with 99mTcDTPA revealed an evident concentration of the radiotracer in the left kidney with effective elimination only after the diuretic stimulus. The right kidney exhibited less concentration of the radiotracer but showed effective elimination before the diuretic stimulus. Image analysis suggested the presence of an extrarenal pelvis on the left side. The relative renal uptake was 68% for the left kidney and 32% for the right kidney. The glomerular filtration rate was 1.65 mL/min/kg. Static renal scintigraphy with 99mTcDMSA revealed irregularity in the distribution of the radiotracer in both kidneys, showing less activity in the caudal pole of the left kidney. The right kidney was apparently reduced and with less activity, especially in the medial portion. The relative renal uptake was 65% for the left kidney and 35% for right kidney, while the absolute renal uptake of the left kidney was 33% and that of the right kidney was 17%. The alteration described in the left kidney, in correlation with dynamic renal scintigraphy, suggested an aspect of lower activity in the caudal pole due to the presence of activity in the extrarenal pelvis. The left kidney was classified as presenting normal renal function and there was moderate to severe deficit of renal function on the right side. Discussion: Chronic kidney disease may be present before clinical signs and biochemical abnormalities are identified. In this report, the animal was referred for a routine evaluation and showed no clinical signs nor alterations on physical examination. However, as renal morphological alterations were seen on ultrasonography and the cat presented mild azotemia, it was decided to perform two renal scintigraphy exams. Despite the radiotracer elimination from the left kidney was seen only after the diuretic stimulus, dynamic renal scintigraphy did not show any obstructive process. This delay on elimination was probably a result of the anatomical variant called extrarenal pelvis. In the static renal scintigraphy, it was possible to evaluate morphological changes in the kidneys and suggest less activity in the caudal pole of the left kidney, due to the presence of activity in the extrarenal pelvis, apparently causing the mentioned defect. The correct diagnosis of morphological changes is essential and for this purpose the best combination of imaging tests is necessary. Renal scintigraphy was fundamental, in this case, for the diagnosis of extrarenal pelvis in one of the kidneys, an abnormality not reported in the feline species within the literature researched by the authors. In addition, renal scintigraphy helped to guide the clinical management of the patient described in this report.

O presente trabalho descreve uma metodologia ativa para auxiliar o ensino-aprendizado na formação de profissionais mais capacitados e contribuir como modelo de estudo para alunos da disciplina de Anatomia Veterinária. A gincana foi realizada com a participação de alunos (n = 48) do primeiro semestre da Faculdade de Medicina Veterinária da Universidade Federal do Pará - Castanhal, no ano de 2018. A turma foi dividida nos grupos A e B, com 24 discentes em cada. O docente (mediador) informou as regras da atividade. Os representantes do grupo A foram alocados em cadeiras individuais de nº 1 a 24 em um lado da sala, o mesmo ocorreu para o grupo B, no lado oposto. A atividade foi iniciada pela dupla da cadeira nº 1 por grupo e finalizada pela dupla da cadeira nº 24. Cada dupla foi chamada pelo mediador da atividade a sentar nos dois bancos no centro da sala, e então foi realizado o ‘par ou ímpar’ com cada dupla para o vencedor escolher um balão pregado na parede da sala, estourar e direcionar o papel que estava no seu interior com as instruções da atividade a ser proposta pelo mediador. As atividades consistiam em 1) responder as perguntas, 2) realizar mímica e 3) participar da “caixa misteriosa”. As pontuações foram acerto (+) ou erro (-), conforme critérios preestabelecidos no papel no interior do balão. A utilização de MA despertou a curiosidade dos alunos, exigindo que eles adquirissem mais conhecimento para poder participar da atividade e apesar de haver restrições na análise de sua efetividade por se tratar apenas de aspectos extraídos da fala dos estudantes, a dinâmica educacional auxiliou no desenvolvimento de competências técnicas e humanísticas. A experiência realizada destaca a importância da difusão de técnicas ativas de ensino, especialmente, em instituições de ensino superior.

The aim of this study was the description of an active learning that can assist the teaching-learning process (TLP) in the formation of more qualified professionals, and to contribute as a study model for students of Veterinary Anatomy. A total of 48 first year students from the Faculty of Veterinary Medicine (Universidade Federal do Pará/Castanhal) participated in the game. The class was divided into groups A and B, with 24 students in each of them. The teacher (mediator) informed the rules of the activity. The representatives of group A were allocated individual chairs from number 1 to 24 on one side of the room, and the same occurred for group B on the opposite side. Each pair was called by the mediator to sit on two benches in the center of the room, and then a game of “odd or even” was played with each pair so that the winner could choose a balloon stuck on the wall of the room, pop it, and send the paper with the instructions of the activity to the mediator. The activities consisted of 1) answering the questions, 2) mimic, and 3) participate in the “mystery box”. The scores were hit (+) or error (-) according to pre-established criteria. The use of TLP aroused the students’ curiosity, demanding that they acquire more knowledge in order to participate in the activity. And although there are restrictions in the analysis of its effectiveness because it deals only with aspects extracted from the students’ speech, the educational dynamics helped in the development of technical and humanistic skills. Thus, the practice applied showed the importance of active learning techniques dissemination, mainly in higher education institutions.

The class was divided into groups A and B, with 24 students in each of them. The teacher (mediator) informed the rules of the activity. The representatives of group A were allocated individual chairs from number 1 to 24 on one side of the room, and the same occurred for group B on the opposite side. Each pair was called by the mediator to sit on two benches in the center of the room, and then a game of “odd or even” was played with each pair so that the winner could choose a balloon stuck on the wall of the room, pop it, and send the paper with the instructions of the activity to the mediator. The activities consisted of 1) answering the questions, 2) mimic, and 3) participate in the “mystery box”. The scores were hit (+) or error (-) according to pre-established criteria. The use of TLP aroused the students curiosity, demanding that they acquire more knowledge in order to participate in the activity. And although there are restrictions in the analysis of its effectiveness because it deals only with aspects extracted from the students speech, the educational dynamics helped in the development of technical and humanistic skills. Thus, the practice applied showed the importance of active learning techniques dissemination, mainly in higher education institutions.(AU)

Some of the most evaluated characteristics are plasma membrane damage, mitochondrial activity, production of reactive oxygen species, sperm DNA damage, and much more. In this review, the potentials and limitations for the implementation of flow cytometry in the seminal analysis of domestic species are explored and commented.

Uso de modelo anatômico para o ensino da técnica de bloqueio regional da porção distal dos membros torácicos em equinos / Anatomical model for teaching the regional anesthesia technique via perineural block of the distal forelimb in horses

A proposta deste trabalho foi desenvolver um modelo de anestesia regional via bloqueio perineural de equinos para complementar o treinamento de habilidades práticas em alunos de graduação em medicina veterinária. Para a base óssea do modelo foi utilizado o membro torácico de um esqueleto equino. Os tendões e ligamentos foram feitos manualmente com porcelana fria e coloridos com tinta guache. A porcelana fria também foi utilizada para fixar as agulhas nos locais anatômicos para a realização dos bloqueios digital palmar, abaxial do sesamoide, quatro pontos baixos e quatro pontos altos. O modelo foi construído em aula prática realizada em laboratório pelos alunos e posteriormente utilizado para comparação com a anatomia de um equino saudável em aula prática realizada em campo. Neste trabalho, o modelo desenvolvido despertou o interesse pelo estudo da anatomia, estimulou o trabalho em grupo e facilitou o entendimento da relação entre as estruturas utilizadas como referência para o correto posicionamento das agulhas. O uso do modelo em aula complementou de forma ilustrativa a explanação teórica realizada pelo docente e foi recebido de forma positiva pelos alunos da disciplina. Desta forma, o modelo experimental se mostrou um bom método complementar para a prática de bloqueios regionais no membro de equinos. As aulas realizadas com o uso do modelo contribuíram para tornar o estudante um profissional mais preparado, confiante e completo, que poderá oferecer um trabalho de qualidade à sociedade.

The aim of the present study was to develop a model of regional anesthesia via perineural block in horses to supplement the teaching of diagnostic analgesia for undergraduate veterinary students. A simulator was built using an equine forelimb skeleton and cold porcelain painted with gouache. Cold porcelain was also used to attach needles in the positions corresponding to the anatomical location of the palmar digital, abaxial and low four-point nerve blocks. The model was developed by the students and used in practical classes based in the laboratory and in the field. The forelimb of a standing healthy horse was placed next to the model for a better understanding of the anatomical sites. In this work, the model encourages the study of anatomy, stimulated group work and enable the understanding of the anatomical reference sites for performing the technique. The use of the model in class complemented in an illustrative way the theoretical explanation made by the teacher and was received positively by the students. The experimental model proved to be a good alternative method for the practice of regional blocks in the equine forelimb. Classes held with the model contributed to professional training and confidence development, which provides a baseline for a better veterinary working.
