Purpose: This study was designed to elicit medical students' opinions on the characteristics of a good ultrasound tutor. The results should help educators to create an optimal teaching environment and inform tutor training.

Materials And Methods: The qualitative study recruited 15 participants from a larger mixed-methods study of 64 medical students who underwent a basic course on abdominal ultrasound taught by faculty and near-peer tutors.

Background: Near-peer teaching is increasingly used in medical education, supporting or replacing faculty teaching. It has positive aspects for learners and tutors, some of which are explained by higher social and cognitive congruence between learners and near-peer tutors (NPTs). This study investigates the optimal combination of faculty tutors (FTs) and NPTs in an abdominal ultrasound course.

Article Synopsis
  • The study highlights the urgent need for effective antimicrobials due to rising antimicrobial-resistant bacteria and investigates the antibacterial properties of silver nanoparticles (AgNPs).
  • AgNPs were found to exhibit strong antibacterial efficacy against various resistant bacterial strains, demonstrating bactericidal activity at low concentrations without causing harm to mammalian cells.
  • The research also revealed that AgNPs could enhance the effectiveness of antibiotics, significantly reducing the required concentrations of aminoglycosides, while remaining non-toxic to human cells.

Accumulating evidence demonstrates a role of the cerebellum in nociception. Some studies suggest that this is mediated via endogenous pain modulation. Here, we used t-DCS to test the effects of modulation of cerebellar function on nociception and endogenous pain modulation.

Near-Peers First, Physician Tutors Last. Interim Report of a Mixed-Methods Study Exploring Optimal Timing in Undergraduate Ultrasound Teaching While many medical undergraduate ultrasound teaching programmes combine teaching from both physician and student ('near-peer') tutors, there has been little research on how these can be optimally combined. In this study, four groups of 16 medical undergraduates each received twelve lessons from student tutors and four lessons from physician tutors as part of their basic ultrasound course.
