Pulmonary aspiration thrombectomy with Lightning Flash catheter in a young patient with fibrosing mediastinitis.

We present the case of a 33-year-old patient with atypical pulmonary anatomy secondary to fibrosing mediastinitis who underwent pulmonary thrombectomy with the Lightning Flash aspiration catheter following a pulmonary embolism triggered by tibial osteomyelitis. Despite an inconclusive computed tomography angiography report, the diagnosis was made through clinical evaluation associated with electrocardiographic and echocardiographic changes. Angiography was crucial for diagnosis.

Cholestatic Hepatitis: A Rare Manifestation of Infectious Mononucleosis.

One of the main clinical manifestations of infection by the Epstein-Barr virus (EBV) is infectious mononucleosis. In this clinical syndrome, mild hepatitis with a slight elevation of aminotransferases is common. However, cholestasis is rare and usually occurs alongside a more severe, cytolytic hepatitis.

Plasmapheresis as an Ischaemic Stroke Treatment: A Rare Case of Acquired Thrombotic Thrombocytopenic Purpura.

Acquired thrombotic thrombocytopenic purpura (acquired TTP) is a rare clinical syndrome caused by a decreased ADAMST13 activity, leading to systemic microvascular thrombotic events, with high mortality rates when the diagnosis and treatment are delayed. The authors report an acquired TTP in a patient with cerebrovascular disease. The aim is to emphasize the importance of considering atypical acquired TTP clinical presentations in order to optimize diagnostic and treatment approaches, minimize possible sequels, and improve the prognosis.

Effects of fine particulate matter air pollution on survival of Heliconius ethilla (Godart, 1819).

Human activities affect natural ecosystems worldwide and can generate negative effects on insect species such as growth inhibition, developmental abnormalities and reduction of reproductive and survival rates. Our study focused on fine particulate matter, a pollutant known to cause mechanical obstruction, heavy metal intoxication, and stress in Lepidoptera larvae. Heliconius ethilla (Lepidoptera: Nymphalidae) is a Heliconiinae found in the southeastern region of Brazil.

Development of an Electrochemical Paper-Based Device Modified with Functionalized Biochar for the Screening of Paracetamol in Substandard Medicines.

The global prevalence of counterfeit and low-quality pharmaceuticals poses significant health risks and challenges in medical treatments, creating a need for rapid and reliable drug screening technologies. This study introduces a cost-effective electrochemical paper-based device (ePAD) modified with functionalized bamboo-derived biochar (BCF) for the detection of paracetamol in substandard medicines. The sensor was fabricated using a custom 3D-printed stencil in PLA, designed for efficient production, and a 60:40 (m/m) graphite (GR) and glass varnish (GV) conductive ink, resulting in a robust and sensitive platform.
