Orientador: Maria Lúcia Gomes Lourenço / Resumo: A doença renal crônica (DRC) é uma alteração com elevada casuística na clínica de pequenos animais, caracterizada por lesão irreversível dos néfrons. Muitos avanços foram realizados na conduta terapêutica do paciente nefropata na clínica de cães e gatos, dentre estes, a instituição da hemodiálise intermitente (HDI), representando um tratamento suporte importante. Em medicina, muitos indicadores relacionados ao risco de mortalidade têm sido explorados, dentre eles a variabilidade da frequência cardíaca (VFC), a dispersão da onda P, bem como a dispersão do intervalo QT já muito estudados, inclusive em pacientes submetidos à hemodiálise. O objetivo do presente estudo consistiu em avaliar a VFC, bem como descrever o perfil arritmogênico de cães portadores de DRC IV submetidos à HDI e compará-los a cães portadores de DRC IV submetidos apenas ao tratamento clínico e a cães saudáveis. Foram utilizados 30 cães, de ambos os sexos, de variadas idades e raças, pesando entre 15 a 30 kg. Os animais foram divididos em três grupos, sendo o grupo I (controle) –com 10 cães saudáveis, grupo II (tratamento clínico) –com 10 cães com DRC em estádio IV, submetidos ao tratamento clínico, duas vezes por semana e grupo III (HDI) –com 10 cães com DRC IV, submetidos, ao tratamento clínico e dialítico, duas vezes por semana. As análises clínicas, laboratoriais, índices de VFC e parâmetros eletrocardiográficos, bem como as dispersões do intervalo QT e onda P foram realizadas nos dois grupos de DRC IV, an...

Many advances have been made in the therapeutic management of the nephropathic patient in the clinic of dogs and cats, among them, the institution of intermittent hemodialysis (IHD), representing an important support treatment. In medicine, many indicators related to mortality risk have been explored, including heart rate variability (HRV), P-wave dispersion, as well as the dispersion of the QT interval already widely studied, including in patients undergoing hemodialysis. The objective of the present study was to evaluate the HRV, as well as to characterize the arrhythmogenic profile of dogs with CKD stage IV undergoing IHD and to compare them to dogs with CKD stage IV submitted only to clinical treatment and to healthy dogs. Thirty dogs of both sexes, of varying ages and races, weighing between 15 and 30 kg were used. The animals were divided into three groups, group I (control) - 10 healthy dogs, group II (clinical treatment) - 10 dogs with CKD IV, submitted to clinical treatment twice a week and group III (IHD) - 10 dogs with CKD IV, submitted, in addition to clinical treatment, to dialysis treatment, with intermittent hemodialysis, twice a week. Clinical, laboratory, HRV indexes and electrocardiographic parameters as well as QT and P-wave dispersions were performed in both CKD groups, prior to and after the end of each clinic...

Orientador: Katia Denise Saraiva Bresciani / Resumo: A Leishmaniose Visceral (LV) apresenta uma ampla distribuição geográfica em todos os continentes, representando um sério problema de Saúde Pública. Os flebotomíneos (Diptera, Psychodidae, Phlebotominae) são importantes insetos vetores de microrganismos patogênicos como Leishmania spp., Bartonella spp. e arbovírus (Vesiculovirus, Phlebovirus, Orbivirus), porém, estes insetos apresentam grande importância para a transmissão das leishmanioses em várias regiões do mundo, incluindo as Américas do Sul e Central. No Brasil, há duas espécies, até o momento, relacionadas com a transmissão da Leishmania infantum: a Lutzomyia longipalpis e a Lutzomyia cruzi. Infecções por Leishmania spp. são potencialmente zoonóticas e acometem homens e diversas espécies de animais silvestres e domésticos. Os cães são importantes hospedeiros, fontes de infecções e potenciais reservatórios, não só pelo estreito relacionamento ou convívio com os seres humanos, mas também por sua incapacidade imunológica em responder à doença com sucesso. O Ministério da Saúde no Brasil, preconiza para o diagnóstico da Leishmaniose Visceral Canina (LVC), o teste imunocromatográfico, como exame de triagem e o ensaio imunoenzimático, como confirmatório. Também recomenda o diagnóstico precoce e tratamento adequado dos casos humanos, o controle dos vetores, a eutanásia dos cães e atividades de educação em saúde nas áreas endêmicas para esta doença. Por tanto, foram instituídas ações de prevenção e controle da LV canina, na áre...

Sand flies (Diptera, Psychodidae, Phlebotominae) are important insect vectors of pathogenic microorganisms such as Leishmania spp., Bartonella spp. and arboviruses (Vesiculovirus, Phlebovirus, Orbivirus), however, these insects are of great importance for leishmaniasis transmission in various regions of the world, including South and Central America. In Brazil, there are two species related to the transmission of Leishmania infantum: Lutzomyia longipalpis and Lutzomyia cruzi. Leishmania spp. infections are potentially zoonotic and affect men and various species of wild and domestic animals. Dogs are important hosts, sources of infections and potential reservoirs, not only for their close relationship or contact with humans, but also for their immunological inability to successfully respond to the disease. The Health Ministry of Brazil recommends for the diagnosis of canine visceral leishmaniasis (CVL), the immunochromatographic test as a screening test and the enzyme immunoassay as confirmatory. It also recommends early diagnosis and appropriate treatment of human cases, vector control, dog euthanasia and health education activities in endemic areas for this disease. Therefore, prevention and control actions of canine VL were instituted in the urban area of municipality of Araçatuba, São Paulo, Brazil. / Doutor

Este estudo permitiu a padronização da densidade mineral óssea (DMO) na extremidade distal do rádio de 36 cães adultos da raça Rottweiler, por meio da densitometria óptica radiográfica. Os membros foram radiografados juntamente com uma escala de referência confeccionada em alumínio. As radiografias foram digitalizadas e analisadas por um programa de computador para comparação de tonalidades de cinza entre as duas imagens da escala de referência (padrão e a radiografada junto ao osso). Posteriormente aos ajustes realizados nos tons da imagem, foram feitas as medições densitométricas no osso, cujos valores foram expressos em milímetros de alumínio (mmAl). Também foram estudadas correlações entre a DMO e o sexo, peso corpóreo e as medidas externas como o comprimento da coluna, altura do animal e circunferência na extremidade distal do membro em estudo. Os valores médios e os desvios-padrão da densidade mineral óssea na extremidade distal do rádio foram: para a região metafisária foi de 7,88 ± 0,89 mmAl, para a região diafisária 1 de 8,58 ± 0,80 mmAl e para região diafisária 2 de 9,00 ± 0,74 mmAl. / This study allowed the standardization of the bone mineral density (BMD) of the distal extremity of the radio of 36 dogs adults in Rottweiler breed by radiographic optic densitometry. The limbs of the animals were radiographed with scale of aluminum that served as a reference. The radiographies images were digitalized and analyzed by a computer program for comparison of gray tones between the standard image and the image of the reference scale radiographed with the bone. Afterwards the values of density were expressed in millimeters of aluminum. Also studied the correlations between BMD and the sex, weight and external measures as the length of spine, height of the animal and circumference the distal extremity of the limb in study. The mean values and standard deviations of the bone mineral density of the distal extremity of the radio were: for the metaphysary region the average of BMD of 7,88 ± 0,89 mmAl, the diaphysary region 1 the average of BMD of 8,58 ± 0,80 mmAl and for diaphysary region 2 of BMD of 9,00 ± 0,74 mmAl.

The use of dogs in a reading program is not a new concept. However, this study addresses the gap in the literature by exploring the connection between reading to dogs, reading self-efficacy, and reading standardized test scores. Using an experimental control group design, this study will look at below-average readers in the fifth grade with half randomly assigned to read once a week to a certified therapy dog and volunteer and the other half randomly assigned to read to just an adult volunteer with no dog. This study will use a reading self-efficacy questionnaire (Carroll & Fox, 2017) and the existing reading standardized test used in the school district. The study should find that reading to dogs has a significant effect on reading self-efficacy and reading standardized test scores. Self-efficacy should mediate the effect of the presence of dogs in the reading group on test scores. This study will contribute to the existing literature on canine-assisted reading programs as well as academic self-efficacy. Though the results are based on local fifth grade students, the study can be replicated in other grades and school districts.

Skeletal remains of the prehistoric New Zealand dog, the kuri, are frequently recovered from archaeological sites. Despite their relative ubiquity only one major study, and the last for twenty five years, has been conducted. That work provided limited anatomical and osteometric information and concluded that the kuri population was homogenous through space and across time. This study set out to provide a more detailed skeletal description and to investigate the question of population homogeneity by examinig kuri skeletal material from five museums and two university anthropology departments. Metric and non-metric data was collected from a total of thirty seven archaeological sites from throuhout New Zealand. Variation within the population was established by comparing coefficients of variation across a number of variables. A program of univariate and multivariate analysis was carried out to examine spatial and temporal variation. Results showed that the appendicular skeleton of the kuri has the highest levels of variation. Smaller limb shaft dimensions of late prehistoric kuri are thought to be due to a reliance on insufficient quantities of marine foods. Tooth wear analysis of late prehistoric dogs showed that they had severe tooth wear compared to �Archaic� dogs.
