Hereditary hemochromatosis beyond hyperferritinemia: Clinical and laboratory investigation of the patient's profile submitted to phlebotomy in two reference centers in southern Brazil.

Hereditary Hemochromatosis is a disorder characterized by iron deposition in several organs and hyperferritinemia. The most studied variants are linked to the HFE gene. In Brazil, surveys that characterize this population are scarce, with no sampling in the state of Rio Grande do Sul.

Identification of rare blood types in southern Brazil: impact on transfusion support.

The prevalence of blood group antigens and phenotypes varies significantly in Brazil. To ensure a proper rare blood supply, it is essential to establish a local and regional database of rare donors connected to the national registry. The objective of this study was to create a database of rare blood donors in the northern region of southern Brazil.

Association of positive direct antiglobulin test (DAT) with nonreactive eluate and drug-induced immune hemolytic anemia (DIHA).

Background And Objectives: Drug-induced immune hemolytic anemia is a rare condition that occurs primarily because of drug-induced antibodies, either dependent or independent and positive direct antiglobulin test. Our aim was to evaluate the association of positive DAT with nonreactive eluate and DIHA.

Materials And Methods: From 2014-2018, we evaluated 159 patients who presented positive DAT with a nonreactive eluate.

"Hey assistant, how can I become a donor?" The case of a conversational agent designed to engage people in blood donation.

Background: People have insufficient knowledge and many misconceptions about the blood donation process, which hampers donors recruitment. Therefore, novel strategies and resources are needed to provide information and improve these circumstances.

Objective: We aimed at an interactive conversational agent to explain about blood donation.
