The results of this study are presented in the form of two scientific papers. The first one refers to the data of a general survey of the main causes of death in this animal category, establishing the epidemiological conditions in which they occur. The second paper describes the epidemiology, clinical signs and pathology of respiratory diseases occuring in the same animal category. Immunohistochemical of cases of enzootic pneumonia suspected to be caused by bovine respiratory syncytial virus were also performed. / Este trabalho teve como objetivo realizar um levantamento das principais enfermidades que acometem bezerros até um ano de idade na área de influência do Laboratório Regional de Diagnóstico da Faculdade de Veterinária da Universidade Federal de Pelotas no período de 2000 a 2011. O trabalho está apresentado na forma de dois artigos científicos. O primeiro deles refere-se os dados de um levantamento geral das principais causas de morte nesta categoria animal, estabelecendo-se as condições epidemiológicas em que as mesmas ocorrem. O segundo trabalho apresenta a epidemiologia, sinais clínicos e patologia das pneumonias que ocorrem nesta mesma categoria animal. Foi realizado também um estudo imuno-histoquímico dos casos de pneumonia enzoótica suspeitos de serem causados pelo vírus respiratório sincicial bovino.

Os objetivos deste estudo foram identificar os fatores de risco para complicações pulmonares pós-operatórias em pacientes laringectomizados por carcinoma espinocelular de laringe, assim como os fatores de risco para apresentação de metástases pulmonares e os fatores de risco para apresentação de segundo tumores primários em pulmão destes pacientes no período de 1985 a 1996. O estudo consistiu em uma análise retrospectiva de 291 pacientes admitidos no Hospital do Câncer A. C. Camargo, no período de 1985 a 1996, portadores de carcinoma espinocelular de laringe, submetidos a tratamento cirúrgico com intenção curativa seguido ou não de radioterapia. Foram analisados as variáveis demográficas, as comorbidades, a localização do sítio primário, o estadiamento clínico, o tratamento do tumor primário e do pescoço, o tratamento radioterápico, a diferenciação celular, as margens cirúrgicas, as recidivas locais, as recidivas regionais, a presença de complicações maiores, de complicações menores, as metástases pulmonares e a presença de múltiplos tumores primários pulmonares. O teste de associação do qui-quadrado foi utilizado para análise univariada descritiva das diversas variáveis comparando-se os grupos com complicação pulmonar e sem complicação pulmonar. A análise multivariada através da regressão logística foi utilizada na determinação dos fatores de risco para apresentação de metástases pulmonares e múltiplos tumores primário pulmonares. A incidência de complicações pulmonares foi de 31,3%, foram identificados como fatores de risco para complicações pulmonares somente a epiglote (p=0,004; RR 2,1), tendo a variável gênero associação marginal (p=0,081; RR 2,8). As metástases pulmonares tiveram incidência de 7,2%, na análise univariada foram identificados como fatores de risco o estadiamento N (p=0,032), diferenciação histológica (p=0,004), margens cirúrgicas (p=0,017) e recidivas locoregionais (0,002). Os múltiplos tumores primários pulmonares apresentaram incidência de 3,1% e na análise univariada foram identificados como fatores de risco o estadiamento N (p=0,048) e sítio aritenóide (p=0,001). Na análise multivariada foram significativos somente a diferenciação histológica: moderamente diferenciado (p=0,007; RR 2,9) e pouco diferenciado (p=0,032; RR 4,0); e as margens cirúrgicas: exíguas (p=0,003; RR 6,4) para apresentação de metástases pulmonares e múltiplos tumores pulmonares. Este estudo demonstra a importância do estadiamento clínico como fator de risco para complicações pulmonares, metástases à distância e múltiplos tumores primário em pulmão. Os fatores de risco determinantes para aparecimento de metástases pulmonares e múltiplos tumores primários pulmonares foram a diferenciação histológica e as margens cirúrgicas / Objective: To identify the risk factors to postoperative pulmonary complications in laryngeal cancer patients submitted to surgical treatment, the risk factors to development of lung metastasis and second lung primary tumor. Patients and Methods: Retrospective study of a cohort of 291 patients admitted at Hospital do Câncer A.C.Camargo from January, 1985 to December 1996. All patients were submitted to some kind of laryngectomy with curative intent as part of treatment of a proven laryngeal cancer, followed or not by radiotherapy. The following variables were analized: demographic, comorbidities, primary site, clinical stage, primary and neck surgical treatment, histopathologic differentiation grade, surgical margins, recurrences, postoperative pulmonary complications, lung metastasis and second lung primary tumor. The univariate and multivariate analysis were utilized to built the model to predict the risks factors and the factors of prognostic significance. Results: The overall pulmonary complications incidence were 31,3%, epiglottis were identified as significant single risk factor to pulmonary complications (p=0.004; RR 2,1). Lung metastasis had 7,2% incidence to this, the risk factors were N stage (p=0.032 ), histopathologic differentiation grade (p=0.004), surgical margins (p=0.017) and locoregional recurrence (p=0.002). The second lung primary tumor incidence were 3,1%, univariate analysis showed N stage (p=0,048) and arithenoid site (p=0,001) as significant risk factors. The multivariate analysis showed the histopathologic differentiation: moderate grade (p=0.007 RR 2,9) and poor grade (p=0.032 RR 4,0) and surgical margins: close (p=0.003 RR 6,4) as prognostic factors to deveopment of lung metastasis and second lung primary tumor. Conclusions: This study showed the clinical stage importance as risk factor to development of postoperative pulmonary complication, lung metastasis and second lung primary tumor in laryngectomy cancer patients. The prognostic factors associated with lung metastasis and second lung primary tumor were the histopathologic differentiation and the surgical margins

Background: Career ending injuries are known to cause negative psychosocial and behavioural outcomes in retired athletes. However, there has been a limited amount of quantitative studies to complement mostly qualitative research. Furthermore, qualitative studies have typically assessed the effects of athletic identity, mental health/mood disturbances, loss, coping mechanisms and social support with minimal research regarding physical body transitions and body-esteem throughout the retirement process. Thus, the purpose of this thesis was to investigate the relationship between affective, behavioural, and cognitive outcomes and athletic retirement (voluntary, involuntary) among elite and competitive athletes. Method: A retrospective mixed method (questionnaire and interview) study was utilized to examine how participants interpreted their experience during the transitional process into retirement. Inclusion criteria consisted of male and female, elite and competitive athletes who have voluntarily or involuntarily (career ending injury) retired, ages 18 and above. Exclusion criteria included non-athletes/recreational athletes, athletes who were able to return to play or retired due to illness, health problems or deselection as well as who were less than 18 years of age. Posters were advertised in sports clubs, fitness centers, sports centers, physiotherapy offices and universities as well as on social media (Facebook and Instagram). The main outcome measures are as follows:1) Athletic Identity Measurement Scale (AIMS); 2) Mood and Feelings Questionnaire (MFQ), 3) Mental Health and 4) COPE Inventory. Semi-structured interviews were conducted with participants from both retirement (voluntary and involuntary) groups. All interviews (telephone, zoom) were recorded, transcribed verbatim and a thematic analysis was implemented to further determine the various themes and subthemes. An independent t-test explored the impacts of body dimensions and coping mechanisms on retirement type. Then a factorial ANOVA was conducted to examine the effects of the dependent variables (mental health, mood disturbances and coping mechanisms) on the main analysis (retirement) and the exploratory (strength of athletic identity) analysis. Results: 50 (26 involuntary and 24 voluntary) questionnaires and eight (four voluntary and four involuntary) interviews were completed by the participants. Results from the quantitative data revealed a borderline main effect of retirement type on both mental health and mood disturbances. An exploratory analysis found retirees who weakly identified with the athletic role were less likely to experience severe mood disturbances and demonstrated higher levels of mental health than retirees who strongly identified with the athletic role. Information from qualitative data suggested participants who involuntarily retired and possessed a strong athletic identity experienced higher levels of mood disturbances (depression, frustrations, loss etc.), lower levels of mental health, identity loss, physical discomfort, negative effects of mind and body dualism as well as utilized maladaptive coping techniques than their counterpart who voluntarily retired or weakly identified with the athletic role. Conclusion: Both retirement types are subjected to various athletic and non-athletic demands and psychosocial effects of athletic retirement however, what sets them apart from experiencing a successful or unsuccessful transition into retirement is the intensity and severity of their emotional reaction to their retirement. Limitations of said study included a decrease in sample size, memory recall bias, the participant’s own bias, limited diversity of the sample population as well as the inability to verify the findings from the interviews. The following study can be implemented to aid researchers, retired or soon to be retired athletes, coaches and athletic personnel to comprehend the diverse areas of athletic retirement. Future research should aim to investigate the impacts of mood disorders, the utilization of psychologist or mental performance consultant during the retirement process as well as the effects of body dimensions in retired athletes. Lastly, a longitudinal study should be employed to examine the athlete’s emotional response and reaction throughout retirement (time of injury, during physiotherapy, post- surgery and recovery). / Graduate
