Influence of apoptosis on liver and spleen resistance in dogs with visceral leishmaniosis

The aim of this study was to evaluate apoptosis and parasite load in the liver and spleen of dogs with visceral leishmaniosis (VL), using immunohistochemistry. Liver and spleen samples from 71 dogs with VL were used. The parasite load in the spleen and liver showed significant difference between organs in infected group (P=0.0219). The density of the parasite load in the spleen (median=2.4) was higher than liver (median=0.8). Immunodetection of apoptotic cells was predominant in lymphocytes and differ between the infected and control group in spleen (P=0.0307) and liver (P=0.0346). There was a significant correlation between apoptosis and parasite load (P = 0.0084; r=0.3104) only in the spleen of the infected group, where it was observed that, when increasing the number of apoptotic cells increases the parasitic load. It was concluded that the liver and spleen of infected dogs presented greater numbers of cells undergoing apoptosis (lymphocytes) than the control group, thus suggesting that this process may be contributing towards the survival of Leishmania in these organs, because lymphocyte in apoptosis did not have the ability to present and recognize the antigen, allowing the survival of the parasite

Triage in an adult emergency service: patient satisfaction

Abstract OBJECTIVE Assess the degree of patient satisfaction with triage in the adult emergency service of a public hospital. METHOD Exploratory, descriptive, cross-sectional study with a quantitative approach. Three hundred patients were interviewed and the data were analyzed using descriptive statistics based on sociodemographic variables and those related to patient satisfaction. RESULTS There was a predominance of women, with elementary education and a mean age of 41 years. Most of the interviewees reported being satisfied in regard to the following items: timely service, embracement, trust, environment (comfort, cleanliness and signage), humanization (courtesy, respect, and interest), timely referral/scheduling of appointments and care expectations. CONCLUSION There was a high level of patient satisfaction, evidenced by the strong association of user satisfaction with the items investigated
