An epidemiological study was carried out in order to characterize the bovine tuberculosis situation and to support the planning and implementation of the National Program for the Control and Eradication of Bovine Tuberculosis in the State of Bahia, owing to the importance of the disease in causing economic burdens and its impact on public health. The State was divided into four regions. In each region, properties were randomly chosen and, a pre-established number of animals was also randomly selected; these animals then subjected to the intradermal comparative cervical tuberculin diagnostic test. Animals with inconclusive test results were retested with the same diagnostic procedure within a minimum interval of 60 days. Within each sampled property, a questionnaire was administered to verify possible risk factors for the disease. In the State, the prevalence of infected herds was 1.6% [1.0–2.6] and that of infected animals 0,21% [0,07; 0,60]. In the regions, the prevalence of infected herds and infected animals were, respectively, 2,0% [1,0; 4,2%] and 2,0% [1,0; 4,2%] in region 1; , 2,9% [1,5; 5,5] and 0,66% [0,20; 2,16] in region 2; 0,3% [0,04; 2,1] and 0,02% [0,002; 0,12] in region 3; and 0,6% [0,2; 2,5] and 0,05% [0,01; 0,20] in region 4. The risk factors associated with tuberculosis infection were dairy farm (odds ratio [OR] = 9.72) or mixed farm (OR = 6.66), and size of herd ? 18 cows ? 24 months of age (OR = 8.44). In conclusion, it is recommended that the State of Bahia implement a surveillance system for the detection of herds with bovine tuberculosis to certifying them in free herds, with special attention to dairy properties, and develop a solid program of health education so that producers test animals for bovine tuberculosis before introducing them into their herds.

SummaryA total of 333 patients with stable intermittent claudication at recruitment were followed up for 6 years to determine risk factors associated with subsequent mortality. Cardiovascular diseases were the underlying cause of death in 78% of the 114 patients who died. The strongest independent predictor of death during the follow-up period was the plasma fibrinogen level, an increase of 1 g/l being associated with a nearly two-fold increase in the probability of death within the next 6 years. Age, low ankle/brachial pressure index and a past history of myocardial infarction also increased the probability of death during the study period. The plasma fibrinogen level is a valuable index of those patients with stable intermittent claudication at high risk of early mortality. The results also provide further evidence for the involvement of fibrinogen in the pathogenesis of arterial disease.

<strong>Objective:</strong> We aimed to evaluate the risk factors associated with acute renal failure in patients who underwent coronary artery bypass surgery.<br /><strong>Methods:</strong> One hundred and six patients who developed renal failure after coronary artery bypass grafting (CABG) constituted the study group (RF group), while 110 patients who did not develop renal failure served as a control group <br />(C group). In addition, the RF group was divided into two subgroups: patients that were treated with conservative methods without the need for hemodialysis (NH group) and patients that required hemodialysis (HR group). Risk factors associated with renal failure were investigated.<br /><strong>Results:</strong> Among the 106 patients that developed renal failure (RF), 80 patients were treated with conservative methods without any need for hemodialysis (NH group); while <br />26 patients required hemodialysis in the postoperative period (HR group). The multivariate analysis showed that diabetes mellitus and the postoperative use of positive inotropes and adrenaline were significant risk factors associated with development of renal failure. In addition, carotid stenosis and postoperative use of adrenaline were found to be significant risk factors associated with hemodialysis-dependent renal failure (P &lt; .05). The mortality in the RF group was determined as 13.2%, while the mortality rate in patients who did not require hemodialysis and those who required hemodialysis was 6.2% and 34%, respectively.<br /><strong>Conclusion:</strong> Renal failure requiring hemodialysis after CABG often results in high morbidity and mortality. Factors affecting microcirculation and atherosclerosis, like diabetes mellitus, carotid artery stenosis, and postoperative vasopressor use remain the major risk factors for the development of renal failure.<br /><br />

Objetivo: Ainda não está claro quais são os fatores de risco para a esquizofrenia resistente ao tratamento (ERT) em primeiro episódio psicótico (PEP). O objetivo deste trabalho é investigar indicadores de risco para ERT em PEP. Métodos: Foram selecionados 53 pacientes em primeiro episódio psicótico, com diagnóstico de esquizofrenia, que deram entrada à enfermaria de psiquiatria do Hospital das Clínicas Luzia de Pinho Melo entre 2011 e 2015. Ao ser admitido na enfermaria, o paciente era avaliado com a Escala de Sintomas para as Síndromes Positiva e Negativa (Positive and Negative Syndrome Scale – PANSS) e recebia tratamento inicial por 4 semanas. Caso sua resposta fosse inferior a 40% de redução na PANSS, o antipsicótico era trocado, e as escalas eram aplicadas novamente após mais 4 semanas. Após a falha com dois antipsicóticos, em doses plenas, por 4 semanas cada, a clozapina era introduzida, e o paciente era considerado ERT. Uma regressão logística foi aplicada onde sexo, idade de início, tempo de doença não tratada, uso de substâncias, avaliação global do funcionamento inicial e PANSS inicial total foram inseridos como variáveis independentes, e ERT foi inserida como variável dependente. Resultados: Tempo de doença não tratada apresentou significância de p = 0,038 e Exp (B) = 4,29, enquanto que PANSS total apresentou p = 0,012 e Exp (B) = 1,06. Conclusão: Identificar os fatores associados à resistência precoce ao tratamento poderia permitir aos clínicos evitar o atraso na introdução da clozapina e prevenir um pior prognóstico para esses pacientes.
