The purpose of this study was to determine the most effective method for bonding composite resin to artificially aged amalgam. A spherical amalgam alloy was triturated and condensed by hand into cylindrical plastic molds (6 mm in diameter and 4 mm in height) to create 90 specimens, which were then aged for 2 weeks in closed plastic containers at 23°C. The amalgam surfaces underwent 1 of 3 surface treatments (n = 30 per treatment): (1) air particle abrasion (APA) with 50-μm aluminum oxide particles applied with a force of 45 psi from a 10-mm distance, followed by rinsing with deionized water for 60 seconds; (2) APA following the same protocol with subsequent application of a metal primer (Alloy Primer); or (3) coating with 30-μm silica (CoJet) at a force of 45 psi from a 10-mm distance until the surface turned black.

The term second victim describes a person involved in patient care who, due to an extraordinary patient care situation, also becomes traumatized. This phenomenon is largely unknown to the general public, although it is widespread, and is being exacerbated by the COVID-19 pandemic. Pronounced psychological strain among clinicians entails the risk of increasing pressure on the healthcare system even further.

A preliminary risk assessment revealed serious risks for both students and patients and had to be addressed by appropriate measures such as mandatory systematic safety training for each student.
Methods: A short-term educational intervention named "Survival-Day" was designed to minimize risks related to nursing internships of students.
Importance: Many of the 4.5 billion annual episodes of diarrhea are treated unnecessarily with antibiotics; prevalence of antibiotic resistance among diarrheal pathogens is increasing. Knowledge-based antibiotic stewardship interventions typically yield little change in antibiotic use.

However, beliefs and behaviors related to antimicrobial resistance are poorly understood. We explored laypersons' and health-care providers' (HCP) awareness and perceptions of antimicrobial resistance in the context of treatment of adult diarrheal disease in Karachi, Pakistan.
