Summary: This systematic review and meta-analysis examined the impact of simulation-based ultrasound training (SIM-UT) in obstetrics and gynecology compared to non-SIM-UT on trainee learning, clinical performance, patient outcomes, and training costs. The results showed that SIM-UT significantly improved trainee learning and clinical performance, with most studies favoring SIM-UT over traditional clinical training methods.

Summary: This paper analyzes the development of quality culture in Taiwan's higher education, which has recently undergone major reforms in quality assurance policies. The implementation of internal quality assurance initiatives is essential for forming a quality culture that fundamentally and comprehensively impacts Taiwanese higher education. Through interviews with policymakers, QA experts, and academics, this paper explores government policy strategies and changes in QA approaches, identifies common features and distinct characteristics of QC in Taiwanese higher education, and examines its relation to QA mechanisms. These perspectives offer a different understanding of QC in QA policies. Furthermore, QC development not only enhances quality in higher education but also drives QA and higher education changes.

Summary: In contemporary academia, accreditation plays a crucial role in maintaining the reputation and delivering quality education. Key Performance Indicators (KPIs) contribute significantly to this process, enabling institutions to assess their performance in important areas. To ensure sustainable accreditation, universities require a comprehensive data management system capable of handling extensive data and generating relevant insights. High-quality education is essential for academic institutions to equip students with necessary skills for societal and economic advancement. A sustainable quality management system emphasizes continuous improvement and long-term planning to enhance overall performance and maintain competitiveness within the sector.

Summary: The aim of this study was to compare the detection rates of malformations before and after the introduction of extended basic screening in Hesse. The study found that the musculoskeletal system had the highest prevalence of congenital malformations, while the nervous system had the highest prenatal detection rate. The introduction of extended basic ultrasound did not improve the detection rates of malformations.

Summary: Three-dimensional (3D) printing of individualized anthropomorphic phantoms offers promising possibilities for assessing and optimizing radiation exposures for specific patient groups. This study aimed to reproduce a conventionally produced female chest and breast phantom using a multi-material extrusion-based printer and evaluate its equivalence with respect to image contrasts and absorbed doses in CT examination. The results demonstrated that 3D-printed phantoms are generally equivalent to conventionally manufactured phantoms in terms of image contrasts and absorbed doses, with minor differences observed.

Summary: Ultrasound has become an essential tool in gynecology, and it is crucial for every gynecologist to be able to distinguish between normal and pathological findings. Standardized settings, indications, and knowledge of normal and common pathological appearances in ultrasound are necessary for safe and confident clinical management. Updated recommendations have been established by DEGUM, oGUM, and SGUM.

Summary: This article argues that a conceptual framework focusing on the technical and social nature of public policy instruments can integrate the instrumental, political, and symbolic dimensions of quality assurance in higher education. Through a comparative analysis of the Chilean and Colombian systems, it highlights contrasting approaches to quality despite initial instrumental similarities.

Summary: This research examines the association between the internal quality assurance system and the continuous improvement of academic program quality in Vietnamese higher education institutions. The findings indicate that while the IQA system in Vietnamese higher education has established infrastructure and used indirect tools, it does not frequently use IQA results to improve educational quality.

Summary: The purpose of this study is to examine the importance of educational processes, practices, and research activities in predicting knowledge skills and employability in Indonesian higher education. The findings show that facilities significantly influence the educational process, but there is no significant relationship between the educational process and employability or between the educational process and knowledge skills. Additionally, practical activities and research activities have a significant impact on employability and knowledge skills.

Summary: Rodent studies suggest that oral metformin use can reduce inflammation, inhibit cell apoptosis, and prolong lifespan. Epidemiological evidence shows that oral metformin use may protect against age-related macular degeneration (AMD) in humans. A systematic review and meta-analysis of nine studies involving 1,427,074 individuals with diabetes found that metformin users had a significantly lower risk of AMD compared to non-users. However, there were inconsistent findings among individual studies and potential publication bias, indicating the need for careful interpretation.

Summary: The study aimed to evaluate the temporal changes in the incidence rates of retinal vein occlusion (RVO) in patients receiving anti-vascular endothelial growth factor (anti-VEGF) treatment, the proportion of patients continuing the treatment over time, and to develop a forecast model for future number of patients with RVO receiving anti-VEGF treatment. The study used registry-based data from patients in the Capital Region of Denmark who started anti-VEGF therapy between January 1, 2007 and June 30, 2022. The results showed that the number of patients increased significantly in the early years of anti-VEGF therapy introduction and then grew slower according to demographic changes. The forecast indicated a continuous, slow growth in the number of patients receiving anti-VEGF therapy for RVO until at least 2035.

Summary: The use of AI in medical education can enhance tasks and efficiency, such as automating assessment of written responses and providing reliable feedback on medical imaging interpretations. However, there is a lack of conceptual or methodological guides for educators in evaluating or conducting AI research. This guide aims to address practical considerations, define terminology, and identify suitable medical education problems and data for AI use.

Summary: This study investigated whether surgeon-performed ultrasonography is as effective as scintigraphy in localizing pathological parathyroid glands in patients with primary hyperparathyroidism. The results showed that conventional ultrasonography by an experienced parathyroid surgeon-sonographer was noninferior to scintigraphy and may be considered as a valid first-line imaging modality.

Summary: This study compared the validity evidence for the assessment of a complex clinical skill using AI-based assessments (AIBA) and expert-based assessments (EBA). Both AIBA and EBA showed validity evidence for scoring, generalisation, extrapolation and implications, but AIBA had weak links in construct representation, explainability, and robustness compared to EBA.

Summary: This study evaluated the safety, efficacy, and preservation of renal function of percutaneous cryoablation (PCA) for small renal masses (SRMs) in patients with inherited renal cell carcinoma (RCC). The results showed that image-guided cryoablation is a safe and effective treatment option for hereditary small kidney cancers, as it maintains good kidney function and controls cancer development. PCA offers low complication rates and achieves good oncological outcomes in patients with hereditary RCC SRMs.

Summary: The study aimed to assess the usability of a newly developed virtual reality (VR) simulator and explore students' self-perceived clinical readiness (SPCR) before and after training with wrist radiographs in the simulator. Results showed that the concept of training with the VR simulator was feasible, with positive feedback from the students. While there was a slight improvement in SPCR scores after the training session, it was not statistically significant.

Summary: This study compared the radiation dose and image quality of standard and ultra-low-dose CT protocols for GE, Canon, and Siemens scanners. The results showed dose reductions of 96%, 68%, and 84% in NCCT and ULDCT, respectively. ULDCT achieved the lowest radiation dose, but slightly compromised image quality compared to standard dose.
