Integrated control of neglected tropical diseases in Brazil: document review of a national campaign in light of WHO recommendations.

Objective: To describe the results of a national campaign aimed at the integrated control of neglected tropical diseases in Brazil in light of the World Health Organization (WHO) official documentation related to the integration of strategies for the prevention, control, and elimination or eradication of neglected tropical diseases.

Methods: A document review that included official WHO documents published between 2007 and 2020 and campaign results extracted from the official technical report produced by the Brazilian Ministry of Health.

Results: The integrated control of neglected tropical diseases was gradually incorporated in the WHO documentation over time.

Impact of socioeconomic status on the knowledge, attitudes, and practices about visceral leishmaniasis among dog owners.

Introduction: This cross-sectional study evaluated the impact of socioeconomic status on the knowledge, attitudes, and practices (KAP) concerning zoonotic visceral leishmaniasis (VL) among dog owners from the municipality of Rondonópolis-a highly endemic area for the disease in Central-Western Brazil.

Methodology: Data were collected between 2016 and 2017 during a household survey. A probabilistic sample of 404 dog owners were interviewed assessing sociodemographic characteristics, previous occurrence of VL cases, and KAP about human VL, vector, and canine VL.

Passive case detection for canine visceral leishmaniasis control in urban Brazil: Determinants of population uptake.

Background: In Brazil, the transmission of Leishmania infantum in urban settings is closely related to infection among dogs, with occasional transmission to humans. Serological screening of dogs for Leishmania spp. infection on requests of their owners (passive case detection) represents a frequent, but little studied, practice within the scope of Brazilian public health.

Hyperendemicity, heterogeneity and spatial overlap of leprosy and cutaneous leishmaniasis in the southern Amazon region of Brazil.

Neglected tropical diseases characterized by skin lesions are highly endemic in the state of Mato Grosso, Brazil. We analyzed the spatial distribution of leprosy and Cutaneous Leishmaniasis (CL) and identified the degree of overlap in their distribution. All new cases of leprosy and CL reported between 2008 and 2017 through the national reporting system were included in the study.

Combining surface-sensitive microscopies for analysis of biological tissues after neural device implantation.

In order to address the complexity of chemical analysis of biological systems, time-of-flight secondary ion mass spectrometry (ToF-SIMS), x-ray photoelectron spectroscopy (XPS), and x-ray photoemission electron microscopy (XPEEM) were used for combined surface imaging of a biological tissue formed around a surface neural device after implantation on a nonhuman primate brain. Results show patterns on biological tissue based on extracellular matrix (ECM) and phospholipid membrane (PM) molecular fragments, which were contrasted through principal component analysis of ToF-SIMS negative spectrum. This chemical differentiation may indicate severe inflammation on tissue with an early case of necrosis.
