Objectives: Three-dimensional reconstruction of patient-specific anatomy and virtual simulation for procedural planning in thoracoscopic segmentectomy could theoretically improve the clinical outcomes. Therefore, the aim of this study was to evaluate the contemporary evidence to test this hypothesis.
Methods: Four databases (PubMed, Embase, Cochrane Library, Web of Science) were searched for articles published before 12 October 2024. Intraoperative parameters (operative time, intraoperative blood loss, the number of lymph node resections, inadequate margin) and postoperative parameters (postoperative complications, total chest drainage, chest tube duration, postoperative hospital stay) were the comparative end-points.
Results: A total of 10 articles were included in this study.772 patients were in the three-dimensional (3 D) reconstruction group and 652 patients were in the non-three-dimensional (Non-3D) reconstruction group. The procedural planning with 3 D reconstruction and simulation reduced the probability of inadequate surgical margins [Odds Ratio (OR) =0.09; 95% confidence interval (CI)=0.02-0.50; P = 0.006] and postoperative complication rates (OR = 0.53; 95% CI = 0.38-0.74; P<0.001).In the subgroup analysis, 3 D reconstruction reduced the operative time [Mean Difference (MD) =-10.85 min; 95% CI=-15.39 to -6.02, P<0.001] and intraoperative blood loss (MD=-5.41 ml; 95% CI=-9.87 to -0.94, P = 0.020) in complex segmentectomies. As for the number of lymph node resections, chest tube duration, total chest drainage, and postoperative hospital stay, the two groups were similar with no statistically significant difference.
Conclusions: Patient-specific 3 D reconstruction and simulation for procedural planning in segmentectomy may help reduce the probability of inadequate surgical margins and complications. In complex segmental resections, it may shorten the operative time and reduce intraoperative blood loss.

Purpose: Real‑time magnetic resonance-guided radiation therapy (MRgRT) integrates MRI with a linear accelerator (Linac) for gating and adaptive radiotherapy, which requires robust image‑quality assurance over a large field of view (FOV). Specialized phantoms capable of accommodating this extensive FOV are therefore essential. This study compares the performance of four commercial MRI phantoms on a 0.

Introduction: The role of imaging in radiotherapy is becoming increasingly important. Verification of imaging parameters prior to treatment planning is essential for safe and effective clinical practice.
Methods: This study described the development and clinical implementation of ImageCompliance, an automated, GUI-based script designed to verify and enforce correct CT and MRI parameters during radiotherapy planning.

Purpose: The development of on-board cone-beam computed tomography (CBCT) has led to improved target localization and evaluation of patient anatomical change throughout the course of radiation therapy. HyperSight, a newly developed on-board CBCT platform by Varian, has been shown to improve image quality and HU fidelity relative to conventional CBCT. The purpose of this study is to benchmark the dose calculation accuracy of Varian's HyperSight cone-beam computed tomography (CBCT) on the Halcyon platform relative to fan-beam CT-based dose calculations and to perform end-to-end testing of HyperSight CBCT-only based treatment planning.

Background: Interventions aimed to increase healthcare provider empathy and capacity to deliver person-centered care have been shown to improve healthcare seeking and outcomes. In the context of self-injectable contraception, empathetic counseling and coaching may be promising approaches for addressing "fear of the needle" among clients interested in using subcutaneous depot medroxyprogesterone (DMPA-SC). In Nigeria, the Delivering Innovation in Self-Care (DISC) project developed and evaluated an empathy-based in-service training and supportive supervision intervention for public sector family (FP) planning providers implemented in conjunction with community-based mobilization.

Background: Live tissue training (LTT) refers to the use of live anaesthetised animals for the purpose of medical education. It is a type of simulation training that is contentious, and there is an ethical imperative for educators to justify the use of animals. This should include scrutinising educational practices.
