This study aimed to ascertain the spatial, environmental, and socioeconomic factors associated with snakebite risk by analyzing notification data of cases in the state of Paraná. Notification and socioeconomic data were gathered from the online platforms of the National System of Notifiable Diseases (SINAN) and the Brazilian Institute of Geography and Statistics (IBGE).

Absence of Trichinella spp. larvae in carcasses of road-killed wild animals in Paraná state, Brazil.

Trichinella spp. are zoonotic parasites that are widely distributed in warm-blooded carnivores and omnivores, including humans. Until the present moment, Brazil has been considered by World Animal Health Organization free from the domestic cycle of trichinellosis, whereas the parasite's sylvatic cycle has the status of infection in limited zones.

High occurrence of viable forms of Cryptosporidium and Giardia in domestic sewage from an agricultural region of Brazil.

Cryptosporidium and Giardia are the main etiologies of waterborne outbreaks caused by protozoa. These parasites are commonly detected in wastewater; however, there is little knowledge about the concentration of viable forms in treated sewage, mainly in small communities. To understand more about the presence of viable oocysts and cysts in domestic sewage, we monitored the affluent and effluent of a wastewater treatment plant (WWTP) in inner-city Brazil.

A total of 408 fecal samples from calves aged 1-60 days were analyzed.

Bee stings in Brazil: Epidemiological aspects in humans.

Bees are insects of the order Hymenoptera and are involved in human accidents. In Brazil, bees that cause accidents are crosses derived from Europeans with African bees and are known for their aggressive behavior. Despite being considered an important public health concern, epidemiological studies at the national level are scarce.

Socioeconomic factors associated with infection by Toxoplasma gondii and Toxocara canis in children.

The intense contact of children with domestic animals or environments contaminated with faeces of these animals, together with habits related to lack of hygiene, can facilitate infection by zoonoses. The study evaluated the seroprevalence and risk factors associated with toxoplasmosis and toxocariasis in schoolchildren in the city of Jataizinho, Paraná. Of the 412 children aged 4-15 years, 56.

American cutaneous leishmaniasis associated with degradation of native forest, regardless of economic, social and infrastructure vulnerability.

American cutaneous leishmaniasis (ACL) is a notifiable dermatozoonosis with relevant morbidity. The present study aimed to evaluate the epidemiological aspects of cases of ACL reported in Northern Paraná (2007-2016), as well as to georeference and analyse the influence of economic, social and environmental variables. Data from ACL notification forms were obtained and the patients' houses were georeferenced.

Toxoplasma gondii and Neospora caninum infections and factors associated in goats in the Parana state, Southern Brazil.

The aim of this study was to determine the occurrence of anti-Toxoplasma gondii and anti-Neospora caninum antibodies and their associated factors among goats in farms from the Paraná state, South Brazil. The serological analysis was performed by indirect ELISA on 629 goat serum samples collected from 32 farms distributed in five mesorregions from the state. Seropositivity was observed in 30.

Isolation, genetic and immunohistochemical identification of Toxoplasma gondii from human placenta in a large toxoplasmosis outbreak in southern Brazil, 2018.

The present study aimed to describe a molecular analysis of environmental and pork samples, the isolation, genetic identification and immunohistochemistry (IHC) of Toxoplama gondii from placenta and amniotic fluid from five pregnant women that miscarried during a toxoplasmosis outbreak in 2018, Santa Maria, Rio Grande do Sul. Environmental and pork samples were submitted to polymerase chain reaction (PCR); placenta and amniotic fluid samples to histopathology, IHC, mouse bioassay and PCR. All samples were genotyped by PCR-RFLP with 11 loci.

Correlation between goniometric and photogrammetric assessment of shank-forefoot alignment in athletes.

Background: The shank-forefoot alignment (SFA) measurement has been previously developed to enhance the applicability of foot alignment measurement in sports preseason assessment because it is reliable and less time consuming. The use of SFA measurements in the clinical context, usually done with photogrammetry, may be simplified by using the universal goniometer and no longer requiring the image processing step that takes additional time and equipment.

Objective: Investigate the correlation between the goniometric and photogrammetric assessment of shank-forefoot alignment in athletes.
