Appropriateness Criteria for Radiation Therapy in the Setting of Presumed Early-Stage Lung Cancer.

Low-dose chest computed tomography imaging for lung cancer screening is revealing increasing numbers of radiographic early-stage lung cancers. This topic discussion describes when a clinical scenario merits radiation therapy without a histologic diagnosis, with an emphasis on pragmatic algorithms in settings without readily available advanced biopsy techniques.

Controlling bacterial growth and inactivation using thin film-based surface acoustic waves.

Formation of bacterial films on structural surfaces often leads to severe contamination of medical devices, hospital equipment, implant materials, , and antimicrobial resistance of microorganisms has indeed become a global health issue. Therefore, effective therapies for controlling infectious and pathogenic bacteria are urgently needed. Being a promising active method for this purpose, surface acoustic waves (SAWs) have merits such as nanoscale earthquake-like vibration/agitation/radiation, acoustic streaming induced circulations, and localised acoustic heating effect in liquids.
