Snail vectors of Schistosoma mansoni in Alagoas, Northeast Brazil: spatial distribution in the hydrographic grid of the state.

Schistosomiasis mansoni is a parasitic infectious disease of significant epidemiological importance caused by Schistosoma mansoni. The intermediate hosts are snails of the genus Biomphalaria spp. As gastropods are crucial for the spread of the disease, this study aimed to assess the influence of water bodies on the distribution of snails responsible for transmitting S.

Sociodemographic aspects, time series and high-risk clusters of malaria in the extra-Amazon region of Brazil: a 22-year study.

Background: Malaria is an acute febrile parasitic disease that significantly impacts global public health. In Brazil, the most studied endemic area for the disease is the Amazon region. This study aims to analyze temporal, spatial, and spatiotemporal patterns of malaria in the extra-Amazon region of Brazil over a 22-year period.

Ultralow Catalytic Loading for Optimised Electrocatalytic Performance of AuPt Nanoparticles to Produce Hydrogen and Ammonia.

The hydrogen evolution and nitrite reduction reactions are key to producing green hydrogen and ammonia. Antenna-reactor nanoparticles hold promise to improve the performances of these transformations under visible-light excitation, by combining plasmonic and catalytic materials. However, current materials involve compromising either on the catalytic activity or the plasmonic enhancement and also lack control of reaction selectivity.

Temporal trend, high-risk spatial and spatiotemporal clustering of leprosy indicators in Brazil: A 20-year ecological and population-based study.

Objectives: Leprosy still represents a public health concern in Brazil. The country is the only one in America not to reach the global goal of leprosy disease control. Hence, this study aimed to assess the temporal, spatial and space-time patterns of leprosy cases in Brazil of the 20-year time series 2001-2020.

Incidence related to accidents caused by venomous animals in the Northeast Region of Brazil: a spatial approach and spatio-temporal retrospective (2008 to 2017).

Accidents with venomous animals correspond to the second cause of epidemiological notification in Brazil, with around 140 thousand cases registered in recent years, which constitutes a serious public health problem. This study aimed to analyze the epidemiological profile and the spatial and spatio-temporal patterns of the incidence of accidents by venomous animals in the Northeast region of Brazil, from 2008 to 2017. We carried out an epidemiological and observational study of an ecological nature, with tools for spatial analysis.

Nuclear Magnetic Resonance Approach in Brazil Nut Oil and the Occurrence of Aflatoxins.

Carcinogenic metabolites of fungi such as aflatoxins play a toxic role in some tree nuts and need to be monitored in their by-products, such as oil. In this context, Brazil nut (Bertholletia excelsa) oil, which is a commodity of great economic importance to Brazil, requires attention to monitor the presence of these toxic agents. Therefore, this study aimed to evaluate the presence of aflatoxins in Brazil nut oil and relate it to the presence of fatty acids in the oil as a surveillance tool for food safety.

Using Palladium and Gold Palladium Nanoparticles Decorated with Molybdenum Oxide for Versatile Hydrogen Peroxide Electroproduction on Graphene Nanoribbons.

Electrocatalytic production of HO via a two-electron oxygen reduction reaction (ORR-2e) is regarded as a highly promising decentralized and environmentally friendly mechanism for the production of this important chemical commodity. However, the underlying challenges related to the development of catalytic materials that contain zero or low content of noble metals and that are relatively more active, selective, and resistant for long-term use have become a huge obstacle for the electroproduction of HO on commercial and industrial scales. The present study reports the synthesis and characterization of low metal-loaded (≤6.

Aspects related to positivity for schistosomiasis: a cross-sectional study in a low prevalence area in Alagoas, Brazil, 2020.

Objective: To analyze aspects related to schistosomiasis positivity in an area of low prevalence in Brazil.

Methods: This was a cross-sectional study, carried out in the first half of 2020, where we analyzed the proportion of positivity, according to the number of Kato-Katz slides, the diagnostic performance of the test and positivity estimates based on data from the Schistosomiasis Surveillance and Control Program Information System (SISPCE).

Results: 2,088 slides from 348 individuals were analyzed, with proportion of positivity of 11.

Primary conjunctival sporotrichosis in three cats from Northeastern Brazil.

Introduction: Classically, sporotrichosis occurs as a chronic granulomatous lymphocutaneous infection. The extracutaneous form is uncommon and may affect the eye without cutaneous involvement. The most frequent form of ocular sporotrichosis reported in humans is a granulomatous conjunctivitis.

New epidemiological profile of schistosomiasis from an area of low prevalence in Brazil.

Introduction: Schistosomiasis, caused by infection from Schistosoma mansoni, is a disease that represents an important public health problem for Brazil, especially for states in the Northeast region. Thus, the aim of this study is to present a new epidemiological profile for the disease in a municipality with low prevalence in the state of Alagoas, Brazil.

Methods: A cross-sectional study was conducted through a coproparasitological and malacological survey.
