Evaluating anti-Orthopoxvirus antibodies in individuals from Brazilian rural areas prior to the bovine vaccinia era

Vaccinia virus naturally circulates in Brazil and is the causative agent of a zoonotic disease known as bovine vaccinia (BV). We retrospectively evaluated two populations from the Amazon and Southeast Regions. BV outbreaks had not been reported in these regions before sample collection. Neutralising antibodies were found in 13 individuals (n = 132) with titres ranging from 100 ≥ 6,400 neutralising units/mL. Univariate analysis identified age and vaccination as statistically significant risk factors in individuals from the Southeast Region. The absence of detectable antibodies in vaccinated individuals raises questions about the protection of smallpox vaccine years after vaccination and reinforces the need for surveillance of Orthopoxvirus in Brazilian populations without evidence of previous outbreaks.

A representação do portador do vírus da imunodeficiência humana sobre o tratamento com os anti-retrovirais

Tendo como objeto de investigação a percepção dos portadores do HIV/AIDS sobre a adesão à terapêutica com medicamentos anti-retrovirais, este estudo de abordagem qualitativa teve como objetivos: conhecer as representações sociais dos portadores do HIV/AIDS sobre a terapêutica medicamentosa e analisar a relação entre a percepção do portador do HIV/AIDS sobre a terapêutica medicamentosa e a motivação para aderir ao tratamento. Os sujeitos do estudo foram nove usuários, internados na unidade de doenças infecciosas de um hospital de ensino na cidade de Juiz de Fora. Os dados foram colhidos através de entrevista semi-estruturada. A categoria de análise permitiu discutir as diversas facetas da adesão aos anti-retrovirais, partindo das representações elaboradas pelos sujeitos que fazem o tratamento, os quais, tomando como mediação o diálogo, falam dos aspectos dificultadores e as motivações para a gestão do tratamento.

Adherence to anti-hypertensive treatment within a chronic disease management program: A longitudinal, retrospective study

Objective This study assessed pharmacological treatment adherence using the Morisky-Green Test and identified related variables. Method A longitudinal and retrospective study examined 283 patients with hypertension (62.5% women, 73.4 [10.9] years old) who were being monitored by a chronic disease management program for 17 months between 2011 and 2012. Nurses performed all the actions of the program, which consisted of advice via telephone and periodic home visits based on the risk stratification of the patients. Results A significant increase in treatment adherence (25.1% vs. 85.5%) and a decrease in blood pressure were observed (p<0.05). Patients with hypertension and chronic renal failure as well as those treated using angiotensin-converting enzyme inhibitors were the most adherent (p<0.05). Patients with hypertension who received angiotensin receptor blockers were less adherent (p<0.05). Conclusions Strategies such as nurse-performed chronic disease management can increase adherence to anti-hypertensive treatment and therefore contribute to the control of blood pressure, minimizing the morbidity profiles of patients with hypertension.
