    Abstract Background: Needle-stick injuries (NSIs) pose a safety risk for healthcare workers with great potential for serious infections. The aim was to determine numbers and causes of NSIs as well as the frequency with which medical students report NSIs in the final stages of study.
    Methods: An online questionnaire was developed and made available in January and February 2023 to all undergraduate medical students (n = 423) in the last 1.5 years of their degree course at Würzburg University, Germany.
    Results: The response rate was 19.6% (n = 84). Among respondents, 27.4% (n = 23) reported at least one NSI. Occurrence was particularly frequent in surgery, obstetrics and gynaecology, and internal medicine. Assisting with procedures, suturing, and blood sampling were considered high-risk activities. Lack of concentration, distraction, and time pressure played a role in incidents. Respondents did not report 18.8% of NSIs with the main reasons being fear of the consequences, self-assessment of the injury as minor, or the opinion of supervisors that reporting was unnecessary. Students with previous practice on simulators or patients were significantly more likely to suffer NSIs. Instructions from occupational health specialists beforehand correlated with fewer NSIs.
    Conclusion: We assume that trained students are more experienced in handling invasive procedures, leading to a greater adoption of corresponding activities and thus an increased risk of injuries in absolute numbers. This does not counter the need for didactic interventions prior to workplace-based training to raise awareness of NSI risks. Simultaneously, concepts must be developed and implemented to support reporting and alleviate fears regarding consequences.

    Abstract Background: Climate change is the greatest threat to human health. Medical students, as future health-care workers, are important in promoting sustainable behaviours, which are strongly associated with individuals' emotional responses to climate change. At Würzburg University Hospital (Würzburg, Germany), a one-term optional course (40 learning units) about planetary health and two lectures within the curricular course Environmental Medicine were introduced in 2021. We aimed to examine the effects of these courses on the emotions and motivations of students in acting against climate change.
    Methods: We surveyed medical students from both courses during four consecutive terms during 2021-23 with a pre-post design using an anonymous online questionnaire on EvaSys. The survey consisted of 20 closed questions based on a 5-point Likert scale and six open questions. Quantitative data were analysed with SPSS version 28.0.1.1. Qualitative data were analysed with Kuckartz' qualitative content analysis.
    Findings: 458 students were initially involved (349 [76%] in the lectures and 109 [24%] in the optional course) and 396 students were involved until the final date (288 [73%] in the lectures and 108 [27%] in the optional course). Mean response rate was 389 (85%) of 458 students pre-survey and 315 (80%) of 396 post-survey. The most frequently reported initial emotions of medical students from both cohorts were "helplessness" (220 [57%] of 389), "fear" (197 [51%]), and "disappointment" (171 [44%]). Only 82 (21%) of 389 students reported having "motivation to act" and 45 (12%) reported having "confidence". When comparing 176 matched pre-lecture and post-lecture Likert scale values of reported emotions, we observed a significant decrease in "helplessness" (mean difference -0·37, 95% CI -0·2 to -0·53; p<0·0001; d=0·34) and "disappointment" (-0·35, -0·2 to -0·49; p<0·0001; d=0·36) and a significant increase in "confidence" (0·67, 0·82 to 0·51; p<0·0001; d=0·65 and "motivation to act" (0·4, 0·53 to 0·27; p<0·0001; d=0·46). Students associated these changes with options for action offered in the lecture.
    Interpretation: This pre-post evaluation provides evidence for a positive effect of planetary health education at the university level. Educators should focus on options for action and create space for improving emotional resilience within courses.

    Abstract Testing based on multiple choice questions (MCQ) is one of the most established forms of assessment, not only in the medical field. Extended matching questions (EMQ) represent a specific type of MCQ designed to require higher levels of cognition, such as problem-solving. The purpose of this evaluation was to assess the suitability and efficiency of EMQ as an assessment method. EMQ were incorporated into the end-of-semester examination in internal medicine, in which 154 students participated, and compared with three established MCQ types. Item and examination quality were investigated, as well as readability and processing time. EMQ were slightly more difficult to score; however, both item discrimination and discrimination index were higher when compared to other item types. EMQ were found to be significantly longer and required more processing time, but readability was improved. Students judged EMQ as clearly challenging, but attributed significantly higher clinical relevance when compared to established MCQ formats. Using the Spearman-Brown prediction, only ten EMQ items would be needed to reproduce the Cronbach's alpha value of 0.75 attained for the overall examination. EMQ proved to be both efficient and suitable when assessing medical students, demonstrating powerful characteristics of reliability. Their expanded use in favor of common MCQ could save examination time without losing out on statistical quality.

    Abstract Multi-parameter mapping (MPM) magnetic resonance imaging (MRI) provides quantitative estimates of the longitudinal and effective transverse relaxation rates R1 and R2*, proton density (PD), and magnetization transfer saturation (MTsat). Thereby, MPM enables better comparability across sites and time than conventional weighted MRI. However, for MPM, several contrasts must be acquired, resulting in prolonged measurement durations and thus preventing MPM's application in clinical routines. State-of-the-art imaging acceleration techniques such as Compressed SENSE (CS), a combination of compressed sensing and sensitivity encoding, can be used to reduce the scan time of MPM. However, the accuracy and precision of the resulting quantitative parameter maps have not been systematically evaluated. In this study, we therefore investigated the effect of CS acceleration on the fidelity and reproducibility of MPM acquisitions. In five healthy volunteers and in a phantom, we compared MPM metrics acquired without imaging acceleration, with the standard acceleration (SENSE factor 2.5), and with Compressed SENSE with acceleration factors 4 and 6 using a 32-channel head coil. We evaluated the reproducibility and repeatability of accelerated MPM using data from three scan sessions in gray and white matter volumes-of-interest (VOIs). Accelerated MPM provided precise and accurate quantitative parameter maps. For most parameters, the results of the CS-accelerated protocols correlated more strongly with the non-accelerated protocol than the standard SENSE-accelerated protocols. Furthermore, for most VOIs and contrasts, coefficients of variation were lower when calculated from data acquired with different imaging accelerations within a single scan session than from data acquired in different scan sessions with the same acceleration method. These results suggest that MPM with Compressed SENSE acceleration factors up to at least 6 yields reproducible quantitative parameter maps that are highly comparable to those acquired without imaging acceleration. Compressed SENSE can thus be used to considerably reduce the scan duration of R1, R2*, PD, and MTsat mapping, and is highly promising for clinical applications of MPM.
