During the preclinical period of medical school, the clinical relevance of theoretical knowledge is given little attention. Medical students of the second year were invited to participate in an interdisciplinary congress for robot-assisted and digital surgery. The students had to evaluate the impact of the congress on their learning motivation, decision-making for a career in surgery, and relevance for their educational curriculum. Participation in the congress increased their learning motivation for preclinical subjects, and significantly increased their interest in a surgical career. Most students considered active involvement in medical congresses a valuable supplement to the medical curriculum. Congress participation during the preclinical period was ranked positively by medical students. Greater learning motivation and enthusiasm for the pilot teaching project as well as for surgical disciplines were registered. Thus, early involvement of medical students in scientific congresses should be an integral part of their educational curriculum.In den vorklinischen Semestern des Medizinstudiums wird der klinischen Relevanz oft wenig Aufmerksamkeit geschenkt. Medizinstudierende des zweiten Studienjahres wurden eingeladen, an einem interdisziplinären Kongress für robotergestützte und digitale Chirurgie teilzunehmen. Im Anschluss sollten die Studierenden den Einfluss des Kongresses auf ihre Lernmotivation, die Entscheidungsfindung für eine Karriere in einem chirurgischen Fach und die Relevanz für das Curriculum bewerten. Durch die Kongressteilnahme steigerte sich die Lernmotivation für vorklinische Fächer, und das Interesse an einer chirurgischen Laufbahn nahm erheblich zu. Die meisten Studierenden betrachteten die aktive Teilnahme an medizinischen Kongressen als wertvolle Ergänzung des Lehrplans für das Studium. Die Kongressteilnahme während der Vorklinik wurde sehr positiv bewertet. Es wurde eine größere Lernmotivation für das Medizinstudium sowie eine Begeisterung für das Pilot-Lehrprojekt und für die chirurgischen Disziplinen registriert. Daher sollte die frühzeitige Einbindung der Medizinstudenten in wissenschaftliche Kongresse ein integraler Bestandteil ihres Curriculums werden.

The use of virtual reality trainers for teaching minimally invasive surgical techniques has been established for a long time in conventional laparoscopy as well as robotic surgery. The aim of the present study was to evaluate the impact of reproducible disruptive factors on the surgeon&rsquo, s work. In a cross-sectional investigation, surgeons were tested with regard to the impact of different disruptive factors when doing exercises on a robotic-surgery simulator (Mimic Flex VRTM). Additionally, we collected data about the participants&rsquo, professional experience, gender, age, expertise in playing an instrument, and expertise in playing video games. The data were collected during DRUS 2019 (Symposium of the German Society for Robot-assisted Urology). Forty-two surgeons attending DRUS 2019 were asked to participate in a virtual robotic stress training unit. The surgeons worked in various specialties (visceral surgery, gynecology, and urology) and had different levels of expertise. The time taken to complete the exercise (TTCE), the final score (FSC), and blood loss (BL) were measured. In the basic exercise with an interactive disruption, TTCE was significantly longer (p &lt, 0.01) and FSC significantly lower (p &lt, 0.05). No significant difference in TTCE, FSC, or BL was noted in the advanced exercise with acoustic disruption. Performance during disruption was not dependent on the level of surgical experience, gender, age, expertise in playing an instrument, or playing video games. A positive correlation was registered between self-estimation and surgical experience. Interactive disruptions have a greater impact on the performance of a surgeon than acoustic ones. Disruption affects the performance of experienced as well as inexperienced surgeons. Disruption in daily surgery should be evaluated and minimized in the interest of the patient&rsquo, s safety.

Background: Live surgery events serve as a valuable tool for surgical education, but also raise ethical concerns about patient safety and professional performance. In the present study, we evaluate the technical feasibility and didactic benefits of live surgery on body donors compared to real patients. Methods: A live surgery session performed on a body donor&rsquo, s cadaver embalmed in ethanol&ndash, glycerol&ndash, lysoformin was integrated into the live surgery program presented at a major gynecological convention of minimally invasive surgery. Surgical procedures carried out in real patients were paralleled in the body donor, including the dissection and illustration of surgically relevant anatomical landmarks. A standardized questionnaire was filled by the participants (n = 208) to evaluate the appropriateness, effectiveness, and benefits of this novel concept. Results: The live surgery event was appreciated as a useful educational tool. With regard to the use of body donors, authenticity was rated high (85.5%), and the overall value of body donors for surgical education and training was rated very high (95.0%). The didactic benefit of simultaneous operations performed on body donors and real patients was considered particularly useful (95.5%), whereas complete replacement of real patients by body donors was not favored (14.5%). Conclusions: The study demonstrated both the technical feasibility and didactic benefits of performing minimally invasive surgery in body donors as part of live surgery events. This novel concept has the potential to enhance anatomical knowledge, providing insights into complex surgical procedures, and may serve to overcome yet unresolved ethical concerns related to live surgery events.

To investigate the effect of ω-3 fatty acids on human meibomian gland epithelial cells (HMGECs, cell line) in vitro. HMGECs were stimulated with docosahexaenoic acid (DHA) or combinations with eicosapentaenoic acid (EPA) and acetyl sialic acid (ASA). Sudan III fat staining, viability and proliferation assays, electric cell-substrate impedance sensing, real-time PCR for gene expression of cyclooxygenase-2 and 15-lipoxygenase and ELISAs for resolvin D1 (RvD1), IFNγ, TNFα and IL-6 were applied. Lipid droplet accumulation and viability was increased by 100 μM DHA in the presence or absence of EPA in serum cultured HMGECs. In contrast, HMGECs cultured with DHA and EPA under serum-free conditions showed minimal lipid accumulation, decreased proliferation and viability. Normalized impedance was significantly reduced in serum-free cultured HMGECs when stimulated with DHA and EPA. HMGECs cultured in serum containing medium showed increased normalized impedance under DHA and EPA stimulation compared to DHA or EPA alone or controls. IL-6 and IFNγ were downregulated in HMGECs treated for 72 h with DHA and EPA. In general, TNFα, IFNγ and IL-6 levels were decreased after 72 h compared to 24 h in serum containing medium with or without DHA or EPA. The concentration of RvD1 was elevated 2-fold after DHA treatment. Cyclooxygenase-2 gene expression decreased compared to controls during DHA stimulation after 72 h. Treatment with DHA and ASA revealed a decreased 15-lipoxygenase gene expression which was reduced after three days of DHA incubation. DHA and EPA supplementation affected HMGECs in vitro and supported anti-inflammatory effects by influencing cytokine levels, decreasing COX-2 expression and increasing the production of RvD1.
