Chest radiographs allow for the meticulous examination of a patient's chest but demands specialized training for proper interpretation. Automated analysis of medical imaging has become increasingly accessible with the advent of machine learning (ML) algorithms. Large labeled datasets are key elements for training and validation of these ML solutions. In this paper we describe the Brazilian labeled chest x-ray dataset, BRAX: an automatically labeled dataset designed to assist researchers in the validation of ML models. The dataset contains 24,959 chest radiography studies from patients presenting to a large general Brazilian hospital. A total of 40,967 images are available in the BRAX dataset. All images have been verified by trained radiologists and de-identified to protect patient privacy. Fourteen labels were derived from free-text radiology reports written in Brazilian Portuguese using Natural Language Processing.

The purpose of the present study was to understand how executives responsible for Diversity and Inclusion construct their identities while occupying positions of "Marginal Leadership," and how they deal with threats to such identities. We conducted qualitative and inductive research with Brazilian executives in 66 organizations, focusing on their experiences as leaders. In our resulting model, we theorized that leaders in positions of Marginal Leadership demonstrate little role clarity, resources, and confidence for the exercise of their activities, suffering threats to their identities, which are not observed in executives occupying positions in more traditional functions such as Finance, Production, and Marketing.

The prevention of coffee fraud through the use of digital and intelligence-based technologies is an analytical challenge because depending on the adulterant, visual inspection is unreliable in roasted and ground coffee due to the similarity in color and texture of the materials used. In this work, a 3D-printed apparatus for smartphone image acquisiton is proposed. The digital images are used to authenticate the geographical origin of indigenous canephora coffees produced at Amazon region, Brazil, against canephora coffees from Espírito Santo, Brazil, and to capture the adulteration of indigenous samples.

Evidence is lacking on alignment of current guidance from the Region of the Americas (AMR) countries with the new guidelines for people with hepatitis B virus (HBV) infection published by the World Health Organization (WHO) in March 2024. We gathered the most updated guidance on HBV infection from organisations/societies and seven countries from AMR. Most guidelines were aligned with the new WHO recommendation to treat persons with elevated ALT and HBV-DNA levels ≥2,000 IU/ml or with HIV-coinfection, hepatocellular carcinoma family history, extra-hepatic manifestations, or immunosuppression.
