Highly Pathogenic Avian Influenza A(H5N1) Virus Infections in Humans.

Background: Highly pathogenic avian influenza A(H5N1) viruses have caused widespread infections in dairy cows and poultry in the United States, with sporadic human cases. We describe characteristics of human A(H5N1) cases identified from March through October 2024 in the United States.

Methods: We analyzed data from persons with laboratory-confirmed A(H5N1) virus infection using a standardized case-report form linked to laboratory results from the Centers for Disease Control and Prevention influenza A/H5 subtyping kit.

Mechanical Deformation Behavior of Polymer Blend Thin Films.

Examining the mechanical properties of polymer thin films is crucial for high-performance applications such as displays, coatings, sensors, and thermal management. It is important to design thin film microstructures that excel in high-demand situations without compromising mechanical integrity. Here, a polymer blend of polystyrene (PS) and polyisoprene (PI) is used as a model to explore microscale deformation behavior under uniaxial mechanical testing.

Venous thromboembolism in transfer trauma patients: A global problem.

Background: As air travel and immobility are risk factors for venous thromboembolism, we aimed to test the hypothesis that internationally transferred trauma patients have a high incidence of venous thromboembolism on arrival.

Methods: A prospectively maintained registry of all international transferred trauma patients who presented to our level I trauma center from January 2023 to June 2024 was retrospectively reviewed. Patients with either lower extremity venous duplex ultrasound or computed tomography scan of the chest with contrast on arrival were included.

Time to Therapy May Not Impact Diagnosis Upstaging in Patients Referred for Management of Luminal Gastrointestinal Neoplasia.

Background: The COVID-19 pandemic dramatically impacted endoscopy practice. Recommendations were to postpone elective cases, including procedures for removal of luminal neoplasia. This provided a natural experiment to evaluate outcomes related to these decisions and the impact of time to procedure on change in histology.

Bioreactor contamination monitoring using off-gassed volatile organic compounds (VOCs).

Metabolically active cells emit volatile organic compounds (VOCs) that can be used in real time to non-invasively monitor the health of cell cultures. We utilized these naturally occurring VOCs in an adapted culture method to detect differences in culturing Chinese hamster ovary (CHO) cells with and without Staphylococcus epidermidis and Aspergillus fumigatus contaminations. The VOC emissions from the cell cultures were extracted and measured from the culture flask headspace using polydimethylsiloxane (PDMS)-coated Twisters, which were subjected to thermal desorption-gas chromatography-mass spectrometry (TD-GC-MS) analysis.
