spp. are facultative pathogens that contribute to the pathogenesis of multiple bovine diseases, including the bovine respiratory disease complex, and have been shown to form biofilms. Biofilm formation is associated with increased antibiotic resistance in many organisms, but accurate determination of antimicrobial susceptibility in biofilms is challenging.

This could limit access to rapid monitoring and increase the diagnostic delay, both of which may be addressed by point-of-care testing (POCT). This study investigated the LumiraDx POC platform for INR monitoring.

- Most research on sonoluminescence and sonochemistry focuses on frequencies above 20 kHz, leaving a gap in understanding bubble dynamics at audible frequencies.
- The study introduces a hybrid modeling approach that combines complex and simpler models to predict heat and mass transfer in bubbles influenced by sound at 17.8 kHz.
- Results show significant deviations between the models at lower frequencies, with the simpler model overestimating bubble size and trapped vapor but underestimating temperature and pressure, highlighting the need for more research in this frequency range.
Anticoagulant therapy in pregnant women with mechanical and bioprosthetic heart valves.

Objective: The aim of the present study was to review maternal and fetal outcomes in pregnant women with prosthetic heart valves.
Methods: A retrospective record review of pregnant women with prosthetic heart valves on anticoagulation was performed at the Specialist Cardiac Antenatal Clinic, Johannesburg South Africa from 2015 to 2023.
Results: Fifty pregnancies with mechanical heart valves and three with tissue valves, on anticoagulation for comorbid atrial fibrillation were identified.
