Mechanical Circulatory Support for Massive Pulmonary Embolism.

Up to 50% of patients with pulmonary embolism (PE) experience hemodynamic instability and approximately 70% of patients who die of PE experience an accelerated cascade of symptoms within the first hours of onset of symptoms, thus necessitating rapid evaluation and intervention. Venoarterial extracorporeal membrane oxygenation and other ventricular assist devices, depending on the hemodynamic derangements present, may be used to stabilize patients with massive PE refractory to initial therapies or with contraindications to other interventions. Given the abnormalities in both pulmonary circulation and gas exchange caused by massive PE, venoarterial extracorporeal membrane oxygenation may be considered the preferred form of mechanical circulatory support for most patients.

High Body Mass Index is Associated with Lower Adalimumab Serum Levels and Higher Disease Activity in Noninfectious Uveitis.

Purpose: Adalimumab, a TNF-alpha inhibitor, is the only FDA-approved biologic for non-infectious uveitis (NIU). However, treatment responses vary, potentially due to interindividual pharmacokinetic differences influenced by body mass index (BMI). This study aimed to evaluate the impact of BMI on adalimumab serum trough levels and therapeutic efficacy in patients with NIU.

Serpiginous-Like Choroiditis with ANCA-PR3 Vasculitis in a Patient from Endemic Country: A Complex Phenotypic, Immunological and Epidemiological Puzzle.

Purpose: To report a complex case of serpiginous-like choroiditis (SLC) in a patient with anti-neutrophil cytoplasmic antibody (ANCA)-anti-proteinase 3 (PR3)-associated vasculitis with systemic involvement.

Methods: Case report.

Results: A 40-year-old male from a tuberculosis (TB)-endemic region presented with bilateral active SLC lesions.

Cross-sectional study on urinary metal concentrations in young adult residents of Emirate of Sharjah, United Arab Emirates.

Background: Human biomonitoring is crucial for regulatory toxicology, yet data on biomarker concentrations in the UAE are lacking. This study addresses this gap by analyzing urinary concentrations of 16 metals in UAE young adults, assessing correlations with personal characteristics, dietary patterns, and lifestyle habits.

Methods: A cross-sectional pilot study was conducted among 144 randomly selected young adults (71 males and 73 females) from Sharjah, UAE, between January and March 2023.
