Rio Grande do Sul (RS) is the second highest state with respect to sporotrichosis incidence in Brazil, with most cases occurring in the southern region. Given the importance of epidemiologic monitoring in hyperendemic areas, this study evaluated the spatial, geographical and annual sporotrichosis incidence over a period of 7 years in the southern region of RS, as well as the disease evolution over the last two decades. Data were collected from the Mycology Laboratory of the Federal University of Rio Grande (FAMED-FURG) and from the Centre for Zoonosis Control (CZC) of the Prefeitura Municipal of Pelotas city. All feline cases of sporotrichosis diagnosed between 2010 and 2016 were included and analysed. In addition, cases of human and canine sporotrichosis were accounted for. Over the 7-year period (2010-2016), 372 feline, 34 canine and 83 human cases of sporotrichosis were diagnosed, being the mean number of cases/year 18.33 in the first 3 years of the study and 116.33 in the last 3 years. Cases were distributed among 34 and 28 neighbourhoods in Rio Grande and Pelotas city, respectively. Socioeconomic features reinforced the result that the disease is already spreading across a major part of the southern region. In addition, the study demonstrated the intensification and expansion of the high endemicity areas. Therefore, given that the number of feline sporotrichosis cases in southern RS reached alarming proportions, we suggested that this region will promptly face an epidemic of sporotrichosis if no preventive or control measures are undertaken.

The application of marine current turbines for electricity generation could offer a distinct advantage over other renewable energy sources due to the regular and predictable nature of this resource. This paper details the application of Analytical Hierarchy Process (AHP) as a possible tool for decision makers to better understand the environment and the impacts of the marine current turbines. The best areas for generating energy from the currents were found using a tridimensional model (TELEMAC3D). In addition to applying the energy conversion module, these regions were also evaluated for energy production, which was then applied to the AHP. Several databases (Transmission and Transport, Socioeconomic, Conservation Units, Endangered Species and Geological Information) were compared to minimize decision deviation. The results showed the viability of the northern region of the Southern Brazilian Shelf (SBS) as a possible area to harvest energy from the currents, as much of the studied region was limited by human activities in the coastal zone and sensitive biological resources.
