Strategic use of 4 % deltamethrin impregnated-collar in seropositive dogs reduces the incidence of seroreactivity to visceral leishmaniasis in dogs from endemic areas.

The effectiveness of a visceral leishmaniasis (VL) control strategy based on the application of 4 % deltamethrin impregnated collars (DIC) exclusively in seropositive dogs was assessed between 2018 and 2019, through a prospective study. The effectiveness of DIC-collaring was evaluated by comparing the incidence rate of anti-leishmanial antibodies among dogs from two endemic districts in Brazil. In one of the areas, the conventional control measure which is based on the non-compulsory euthanasia of LV seropositive dogs, was practiced by the official healthy service as a regular procedure, whereas strategic collaring, conceived in this study, was carried out in the other.

Prevalence of self-reported chronic kidney disease in Brazil: National Health Survey of 2013.

Objective: To describe the profile of adults who reported medical diagnosis of chronic kidney disease (CKD), according to selected variables.

Methods: In a cross-sectional study with individuals included in the National Health Survey of 2013, a household population-based study was conducted in rural and urban areas of Brazil. A total of 60,202 individuals aged ≥ 18 years who self-reported a medical diagnosis of chronic renal failure or kidney disease were evaluated.
