Risk Factors for Blood Transfusion with Neck Dissection.

Objectives: To identify risk factors of perioperative blood transfusions (PBTs) for neck dissection and identify the association of PBTs with other postoperative outcomes.

Methods: This is a retrospective study of the American College of Surgeons National Surgical Quality Improvement Program (ACS-NSQIP) database. The database was queried for neck dissection procedures performed by otolaryngologists from 2006 to 2014.

Gemini Cationic Amphiphiles Control Biofilm Formation by Bacterial Vaginosis Pathogens.

Antibiotic resistance and recurrence of bacterial vaginosis (BV), a polymicrobial infection, justify the need for novel antimicrobials to counteract microbial resistance to conventional antibiotics. Previously, two series of cationic amphiphiles (CAms) which self-assemble into supramolecular nanostructures with membrane-lytic properties were designed with hydrophilic head groups and nonpolar domains. The combination of CAms and commonly prescribed antibiotics is suggested as a promising strategy for targeting microorganisms that are resistant to conventional antibiotics.
