Objective: The aim of this study was to investigate whether the degree of urbanization influences the prevalence of chronic kidney disease in Brazilian indigenous people.
Methods: This is a cross-sectional study conducted between 2016 and 2017 in northeastern Brazil and includes individuals aged between 30 and 70 years from two specific indigenous groups who volunteered to participate in the study: the Fulni-ô people (lowest degree of urbanization) and the Truká group (greater degree of urbanization). Cultural and geographical parameters were used to characterize and measure the magnitude of urbanization.
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).

Article Synopsis
- Chikungunya fever (CHIKF) is a significant global health issue affecting over 2 million people since 2005, particularly impacting vulnerable groups like Indigenous populations, with limited epidemiological data available.
- The study aimed to analyze the serological and epidemiological profiles of chikungunya virus in two Indigenous tribes in Northeast Brazil, comparing them to an urbanized non-Indigenous community, while examining correlations with physical health measurements.
- Findings revealed a 49.9% overall prevalence of CHIKV antibodies, with a striking 78.3% positivity in the Fulni-ô group, no cases in the Truká tribe, and 5.8% in the urban control group, highlighting the variations in

Unlabelled: Cerebral embolism from cardiac source is an important cause of stroke, specially in patients younger than 45 years old.
Objective: To describe the transesophageal echocardiography (TEE) findings in young and non-young stroke patients without any prior evidence of cardiac source for cerebral embolism.
Method: Transversal study: 523 patients (267 men and 256 women) with ischemic stroke, without any evidence of cardiac abnormality, underwent to TEE.
