Sexual History-Taking in a Surgery Clerkship Assessment: A Stubborn Clinical Skills Gap With Reproductive Health Care Implications.

Purpose: Patients present with sexual and reproductive health needs in a variety of clinical settings, so knowing when and how to elicit a relevant sexual history is critical in any specialty. This work examined whether reinforcing the surgical relevance of sexual health with an integrated training improved third-year medical students' sexual history-taking.

Method: Third-year surgery clerkship standardized patient assessments were video coded from a 2021-2022 comparison and 2022-2023 intervention cohort (University of Louisville School of Medicine).

Assessing Abdominal Examination Skills in a Surgery Clerkship Standardized Patient Encounter for Curriculum Improvement.

Introduction: Standardized patient (SP) encounters allow medical students to practice physical examination skills and clinical reasoning. SP cases are used for learning and assessment, but recorded encounters can also be valuable curriculum evaluation tools. We aimed to review SP encounters to improve abdominal examination skills and the broader physical examination curriculum.

Calculating shear viscosity with confined non-equilibrium molecular dynamics: a case study on hematite - PAO-2 lubricant.

The behaviour of confined lubricants at the atomic scale as affected by the interactions at the surface-lubricant interface is relevant in a range of technological applications in areas such as the automotive industry. In this paper, by performing fully atomistic molecular dynamics, we investigate the regime where the viscosity starts to deviate from the bulk behaviour, a topic of great practical and scientific relevance. The simulations consist of setting up a shear flow by confining the lubricant between iron oxide surfaces.

Local application of engineered insulin-like growth factor I mRNA demonstrates regenerative therapeutic potential .

Insulin-like growth factor I (IGF-I) is a growth-promoting anabolic hormone that fosters cell growth and tissue homeostasis. IGF-I deficiency is associated with several diseases, including growth disorders and neurological and musculoskeletal diseases due to impaired regeneration. Despite the vast regenerative potential of IGF-I, its unfavorable pharmacokinetic profile has prevented it from being used therapeutically.

Computing Viscosities of Mixtures of Ester-Based Lubricants at Different Temperatures.

Synthetic esters are used as lubricants for applications at high temperatures, but their development can be a trial and error process. In this context, molecular dynamics simulations could be used as a tool to investigate the properties of new lubricants, in particular viscosity. We employ nonequilibrium molecular dynamics (NEMD) simulations to predict bulk Newtonian viscosities of a set of mixtures of two esters, di(2-ethylhexyl) sebacate (DEHS) and di(2-ethylhexyl) adipate (DEHA) at 293 and 343 K as well as equilibrium molecular dynamics (EMD) and NEMD at 393 K and compare these to experimental measurements.
