ERCP for the initial management of malignant biliary obstruction - real world data on 596 procedures.

Aims: To evaluate outcomes of ERCP as first-line management in patients with malignant biliary obstruction (MBO) of all causes and stages, reflecting a real-life setting.

Methods: Retrospective observational study of patients with ERCP as the first-line management of MBO at Oslo University Hospital between 2015 and 2021. Primary outcome measure was  ≥ 50% decrease from the pre-procedural bilirubin within 30 days after ERCP.

Update of the diagnostic criteria of brain death: application and training of physicians.

Objective: To evaluate the medical knowledge regarding the application of the diagnostic criteria for brain death and to correlate it with training parameters for this diagnosis according to Federal Council of Medicine resolution 2,173 of 2017.

Method: We interviewed 174 physicians with experience with comatose patients. A structured questionnaire adapted from previous studies was used.

Use of iron ore tailing from tailing dam as catalyst in a fenton-like process for methylene blue oxidation in continuous flow mode.

The global demand for iron ore with high iron contents to supply the steel industry is associated, in most countries, with the generation of tailings from mineral processing. The chemical compositions of iron ore tailings (basically FeO and SiO) make them an excellent candidate as a catalyst for advanced oxidation processes (AOPs), especially the Fenton process and its derivatives. Therefore, this paper aimed to transform iron ore tailings from tailing dams into catalysts able to activate HO for the purpose of treating, in a continuous flow, effluents contaminated with organic dyes, employing methylene blue as a model molecule.

Acute disseminated paracoccidioidomycosis in a 3 year-old child.

Clinical cases involving paracoccidioidomycosis in children, diagnosed in Mato Grosso State, in the central western region of Brazil, are rare despite the state being classified with a moderate to high incidence. We describe a clinical case of infant acute disseminated Paracoccidioidomycosis in Mato Grosso State, Brazil, highlighting the importance of early differential diagnosis from other severe pathologies, thus contributing to the survival of compromised patients. A 3 year-old male child, weighing 12.
