Generating realistic virtual patients from a limited amount of patient data is one of the major challenges for quantitative systems pharmacology modeling in immuno-oncology. Quantitative systems pharmacology (QSP) is a mathematical modeling methodology that integrates mechanistic knowledge of biological systems to investigate dynamics in a whole system during disease progression and drug treatment. In the present analysis, we parameterized our previously published QSP model of the cancer-immunity cycle to non-small cell lung cancer (NSCLC) and generated a virtual patient cohort to predict clinical response to PD-L1 inhibition in NSCLC. The virtual patient generation was guided by immunogenomic data from iAtlas portal and population pharmacokinetic data of durvalumab, a PD-L1 inhibitor. With virtual patients generated following the immunogenomic data distribution, our model predicted a response rate of 18.6% (95% bootstrap confidence interval: 13.3-24.2%) and identified CD8/Treg ratio as a potential predictive biomarker in addition to PD-L1 expression and tumor mutational burden. We demonstrated that omics data served as a reliable resource for virtual patient generation techniques in immuno-oncology using QSP models.

Background: Stroke, frequently associated with carotid artery disease, is evaluated using carotid computed tomography angiography (CTA). Dual-energy CTA (DE-CTA) enhances imaging quality but presents challenges in maintaining high image clarity with low-dose scans.
Objectives: To compare the image quality of 50 keV virtual monoenergetic images (VMI) generated using Deep Learning Image Reconstruction (DLIR) and Adaptive Statistical Iterative Reconstruction-V (ASIR-V) algorithms under a triple-low scanning protocol in carotid CTA.
Background: To help reduce mental health disparities in the transgender and gender diverse (TGD) population, there is a need to equip future psychiatric mental health nurse practitioners (PMHNPs) with affirming care competence.
Method: This study evaluated a multimodal education program that combined eLearning with two virtual standardized patient (SP) simulations to teach PMHNP students to provide affirming mental health care to TGD people.
Results: Slight increases in knowledge and attitudes were not practically applicable.

Purpose: The purposes of this study were threefold: (1) to evaluate the influence of femoral antecurvature on coronal alignment changes following supracondylar femoral derotational osteotomy (FDO); (2) to investigate the combined effects of derotation angle and osteotomy orientation in relation to femoral antecurvature and (3) to propose a practical strategy for minimising valgus deviation after FDO based sagittal femoral bowing.
Materials And Methods: Sixty-six cadaveric femoral computed tomography (CT) scans were analysed using three-dimensional (3D) simulation. Femurs were classified into three groups based on the degree of antecurvature using the distal diaphyseal angle (DDA).

Background: Intrauterine devices (IUDs) are safe and effective long-acting reversible contraceptive therapies that are also used as minimally invasive treatment for heavy menstrual bleeding, endometrial hyperplasia, and early-stage endometrial cancer. Despite many advantages, IUDs are underused predominantly due to patient discomfort. Although many techniques have been explored previously in the literature, there is currently little consensus on effective analgesic strategies.

Introduction: Developing and implementing trauma clinical guidance is integral to providing quality care to all trauma patients while maintaining a minimum standard of treatment. A mixed-methods novel consensus-building approach was used to identify the current barriers to developing and implementing trauma clinical guidance and highlight the priority areas for change to better support end users.
Methods: As part of year 1 of the Design for Implementation: The Future of Trauma Clinical Guidance and Research Conference Series, preconference participant surveys and hybrid, professionally facilitated, structured dialogue were used to define the ideal future state of trauma clinical guidance development and dissemination.
