Anatomopathological characterization of hepatic lesions of feline infectious peritonitis in cats.

Feline infectious peritonitis (FIP) is one of the most important infectious diseases and a significant cause of death in cats. While the pathology of FIP has been well documented, there is little information on the hepatic lesions. The aim of this study was to characterize the macroscopic, microscopic and immunohistochemical patterns of the liver lesions in cats with FIP.

Prevalence and associated factors of chronic kidney disease among Truká Indigenous adults in Cabrobó, Brazil: a population-based study.

Background: The prevalence of chronic kidney disease (CKD) is increasing worldwide, especially in developing countries, due to factors such as lifestyle changes and the rise of non-communicable diseases. Populations living in socioeconomically disadvantaged areas are subject to a higher burden of CKD. However, the burden of CKD on Brazilian Indigenous people, especially those undergoing an advanced urbanisation process, has not yet been described.

Oral health of an indigenous population in northeastern Brazil: a cross-sectional Study of the Fulni-ô ethnic group.

Background: There is a lack of studies evaluating the oral health of traditional indigenous communities in Brazil.

Objectives: Thus, the objective of this study was to describe the oral health characteristics of the indigenous Fulni-ô ethnic group in Northeast Brazil.

Design And Setting: A cross-sectional observational investigation was conducted within the Project on Atherosclerosis among Indigenous Populations.

Epidemiology of chronic kidney disease in older indigenous peoples of Brazil: findings from a cross-sectional survey.

Background: Chronic kidney disease (CKD) is a prevalent disease worldwide, with increasing incidence particularly in low- and middle-income countries. Indigenous communities have poorer CKD outcomes due to limited access to healthcare. They are also experiencing a shift toward a sedentary lifestyle and urbanization-related dietary changes, increasing the risk of CKD-related risk factors.

Urbanization and cardiovascular health among Indigenous groups in Brazil.

Background: We described the prevalence of cardiovascular risk factors in groups of Brazilian Indigenous people at different degrees of urbanization.

Methods: The Project of Atherosclerosis among Indigenous populations (Projeto de Aterosclerose em Indígenas; PAI) is a cross-sectional study conducted in Northeast Brazil between August 2016-June 2017. It included three populations: Fulni-ô Indigenous people (lowest degree of urbanization), Truká Indigenous people (greater urbanization), and a highly urbanized non-Indigenous local cohort (control group).

Association of polymorphisms in long pentraxin 3 and its plasma levels with COVID-19 severity.

COVID-19 is an infectious respiratory disease caused by SARS-CoV-2. Pentraxin 3 (PTX3) is involved in the activation and regulation of the complement system, demonstrating an important role in the pathogenesis of COVID-19. The aim was to evaluate the association of single nucleotide polymorphisms in PTX3 and its plasma levels with the severity of COVID-19.

Clinical characteristics and laboratory parameters associated with the risk of severe COVID-19 in patients from two hospitals in Northeast Brazil.

Background: Although most coronavirus disease 2019 (COVID-19) infections are mild, some patients have severe clinical conditions requiring hospitalization. Data on the severity of COVID-19 in Brazil are scarce and are limited to public databases. This study aimed to investigate the clinical and laboratory factors associated with the severity of COVID-19 in a cohort of hospitalized adults from two hospitals in Northeast Brazil.

Epigenetic and parasitological parameters are modulated in EBi3-/- mice infected with Schistosoma mansoni.

Schistosoma mansoni adaptive success is related to regulation of replication, transcription and translation inside and outside the intermediate and definitive host. We hypothesize that S. mansoni alters its epigenetic state in response to the mammalian host immune system, reprogramming gene expression and altering the number of eggs.

Clinical and molecular findings in a cohort of ANO5-related myopathy.

Objective: ANO5-related myopathy is an important cause of limb-girdle muscular dystrophy (LGMD) and hyperCKemia. The main descriptions have emerged from European cohorts, and the burden of the disease worldwide is unclear. We provide a detailed characterization of a large Brazilian cohort of ANO5 patients.

Direct Determination of Nimesulide in Natural Waters and Wastewater by Cathodic Stripping Voltammetry.

Pharmaceuticals are included in a group of compounds considered as contaminants of emerging concern (CECs) in environmental matrices. The quantification of CECs is typically accomplished using chromatographic methods that require several sample pretreatment steps. The current study proposes a voltammetric method to quantify directly nimesulide (NIM) in aqueous samples.

Stroke as the First Clinical Manifestation of Takayasu's Arteritis.

Takayasu's arteritis is a chronic inflammatory disease, and neurological symptoms occur in 50% of cases, most commonly including headache, dizziness, visual disturbances, convulsive crisis, transient ischemic attack, stroke and posterior reversible encephalopathy syndrome. The aim of this study was to report the case of a young Brazilian female with a focal neurological deficit. She presented with asymmetry of brachial and radial pulses, aphasia, dysarthria and right hemiplegia.

Contamination of public parks in Presidente Prudente (São Paulo, Brazil) by Toxocara spp. eggs.

This study aims to evaluate soil contamination by Toxocara spp. eggs in public parks in Presidente Prudente, São Paulo, Brazil. Soil samples (500 g) were collected every month over a 12-month period, from 25 parks in different parts of the city (northern, southern, eastern, western and central areas).
