From Diagnosis to Emergency: Mediastinal Abscess After Endobronchial Ultrasound-Guided Transbronchial Needle Aspiration in a Patient With Sarcoidosis.

Sarcoidosis is a systemic granulomatous disease of unknown etiology, primarily affecting the lungs and the lymphatic system. Its diagnosis is challenging, and in many cases, it requires histopathological confirmation through the identification of non-caseating granulomas. The presented case illustrates its diagnostic complexity and highlights a rare, delayed complication associated with endobronchial ultrasound-guided transbronchial needle aspiration (EBUS-TBNA).

An Uncommon Presentation of Guillain-Barré Syndrome With Lhermitte Sign.

Guillain-Barré syndrome (GBS) is a complex and potentially life-threatening disease, representing the most common cause of acute neuromuscular paralysis worldwide. Its diagnosis is primarily based on clinical findings, often complemented by electrophysiological studies and laboratory investigations. Therefore, knowledge of the clinical signs and symptoms is essential to make a prompt diagnosis and allow timely initiation of therapeutic interventions.

Direct and transgenerational effects of simvastatin on the metabolism of the amphipod Gammarus locusta.

In this study, untargeted Nuclear Magnetic Resonance (NMR) metabolomics was applied for the first time, to our knowledge, to assess the metabolic impact of direct and transgenerational exposure (F0 and F3 generations, respectively) of amphipods Gammarus locusta to simvastatin (SIM), a pharmaceutical widely prescribed for the treatment of hypercholesterolemia. Results revealed the important gender-dependent nature of each of these effects. Directly exposed males showed enhanced glucose catabolism and tricarboxylic acid (TCA) cycle activity, in tandem with adaptations in osmotic regulation and glyoxylate metabolism.

Isotemporal substitution of physical activity patterns and sitting time with obesity indicators among workers in São Paulo.

This study aimed to evaluate the association between substituting 10, 30, and 60 min/day of physical activity and sitting time with obesity indicators among workers. It is a cross-sectional study involving 394 adults (76.6% women) from São Paulo, Brazil.
