Babesia spp. and Ehrlichia chaffeensis infection in Dogs from Southeastern Bahia, Brazil

Background: Tickborne diseases are frequent in tropical countries such as Brazil. Protozoa of the Babesia genus and bacteria of the Ehrlichia genus spread throughout the country with high prevalences in urban and rural areas, causing clinical or subclinical diseases in dogs. This study aimed to investigate the prevalence of infection from Babesia spp. and Ehrlichia chaffeensis in the dog population in the municipality of Ituberá, Bahia, Brazil, and to verify the risk factors associated with the infections.Materials, Methods & Results: A cross-sectional study was conducted, consisting of the following procedures: clinical examination and blood samples collection from 380 dogs and application of a structure questionnaire to dog owners to collect epidemiological data. All dogs were evaluated for the presence of ticks and clinical signs associated with the infections. Blood samples were collected and tested for Babesia spp. through capillary blood smears, indirect immunofluorescence assays (IFAT), and polymerase chain reaction (PCR); all the samples were also tested for E. chaffeensis through nested PCR. Intra-erythrocyte piroplasms were visualized in the blood smears of two animals (2/380; 0.5%) in the cytology exams. Anti-B. canis antibodies were detected in 140/380 (36.8%) dogs, at 1:40 dilution. By PCR, 147/380 (38.7%) dogs tested positive for infection by Babesia sp., but no animal was infected by E. chaffeensis. Only 115/380 dogs (30.3%) were infested by ticks. In total, 223/380 dogs (58.7%) were found infected by Babesia spp. No clinical signs were it found to be significant for the infection. The infected (Ht = 40%) and uninfected dogs’ (Ht = 39%) hematocrit averages were not found to significantly differ (P = 0.47). No hematological changes were found to be significant for the disease. The evaluated variables sex, habitat (urban or rural), exposure to other dogs, age, and infestation by ticks were not found to be risk factors. The condition of semirestriction of 175/223 (78.4%) dogs was found as a risk factor for the infection (P = 0.01; OR = 1.75; IC 95% = 1.10-2.78).Discussion: The low detection from blood smears was inferior to the lowest prevalences found in Brazil. On the other hand, the high seroprevalence rate by IFAT observed in this study was found in other Brazilian states.  The low infection prevalence in the cytologic analysis associated with high seroprevalence are characteristics of chronic or subclinical infections. The high seroprevalence rates may also indicate chronicity and/or subclinical disease when associated with low parasitemia and may also be indicated by the low title variation observed. In this study, some dogs that tested positive for Babesia by serology tested negative in the PCR, which suggests a previously exposure to this pathogen and maintenance of detectable levels of antibodies, or that they were subclinical or chronic carriers of the infection. The equal hematocrit averages of dogs either carrying or not the disease suggests that the infected animals, especially the seemingly healthy dogs, are subclinical or chronic carriers, either asymptomatic or otherwise, that are adapted to the disease, which may contribute to the agent remaining in this population. The fact that no clinical sign of hematological change was significant for the infection may demonstrate the low pathogenicity of this agent in the evaluated population. The semi-restricted condition of the dogs as a risk factor is probably due to the increased exposure of these animals to canine babesiosis vectors during their movement through different neighborhood areas and villages in the municipality. The combination of diagnostic methods is important to identify the infection and determine its prevalence in epidemiological studies. Also, PCR was fundamental in this study, to identify the infection in asymptomatic dogs

Cardiopulmonary Re-Immonation (CPR): How Long Should A Person Insist On Performing The Maneuvers?

Objetive: The study had the aim to describe the exact moment of interrupting CPR maneuvers in patients in CRP situations. Method: This is an exploratory and descriptive research, with quantitative character and approach. It was performed with 67 (seventy-seven) nurses from a Regional Hospital, who were informed about the objectives of the same. There were included those who act in direct patient care; of effective position and contracted in the service; And with more than one (1) year of training. The instrument used for data collection was a questionnaire, previously elaborated, containing objective, subjective and non-inductive questions, which allowed the informant to answer the data pertinent to the study. It was found that the majority of the interviewees were women, aged between 31 and 35 years, specialists, with more than 4 years of training and 3 years of service, medical / surgical clinic attendees, and without reports of training. Results: They demonstrated they know the exact timing of CPR maneuvers but reported that they would not apply CPR in situations in which the patient had cadaveric stiffness, decomposition, crushing of the skull and thorax, or a CPA report of more than 20 minutes. Faced with conditions in which the team could decide not to perform CPR, they reported not applying CPR in the vegetative state, in terminal or chronic patients. Conclusion: Therefore, they conclude that the said moment of interrupting the protocol is determined in a personal and ethical way, that is, by the individuality of each situation. Keywords: Nurses.

Implantação do e-SUS AB no Distrito Sanitário IV de João Pessoa (PB): relato de experiência

RESUMO Os sistemas de informação têm o propósito de auxiliar os gestores nas tomadas de decisões. O e-SUS AB facilita e contribui para a organização do trabalho dos profissionais de saúde na Atenção Básica. O presente artigo tem o objetivo de apresentar o processo de implantação e desenvolvimento do e-SUS AB no Distrito Sanitário IV de João Pessoa (PB), em 2014. Trata-se de um estudo descritivo, na forma de relato de experiência, o qual aponta as dificuldades e qualidades do sistema. Conclui-se que os esforços para reestruturação do sistema só serão efetivos com o apoio dos envolvidos na implantação, na utilização e no aprimoramento do Sistema de Informação em Saúde da Atenção Básica (Sisab) e da estratégia e-SUS AB
