«Label-Chain» : Konzeption & Entwicklung eines Blockchain-Prototyps im Bereich Supply-Chain-Management

Aktuell wird die Blockchain von CEOs und weltweitem Fachpublikum als eine Technologie, die das Potenzial einer «ökonomischen Revolution» in sich birgt, bezeichnet. Auch führende amerikanische Marktforschungs- und IT-Beratungsunternehmen schätzen die Technologie als aktuellen Hype im IT-Bereich ein. Nun gilt es, diese Trend-Technologie auf deren tatsächliche Praxistauglichkeit zu untersuchen, mit der Fragestellung, wie das Anwendungspotenzial der Blockchain-Technologie für eine Schweizer Organisation einzustufen ist. Im Rahmen der Erarbeitung der Master Thesis kann festgestellt werden, dass beim Einsatz der Blockchain im Supply Chain Management oftmals das Ziel der erhöhten Rückverfolgbarkeit genannt wird. Jedoch kann dies in diversen Fällen auch von einer vertrauenswürdigen Drittpartei übernommen werden und ist daher nicht geeignet für die Anwendung einer Blockchain. Eine weitere Problematik ist der Link zwischen der physischen und digitalen Welt, respektive ob ein Produkt authentisch ist und den digitalen Angaben der Blockchain entspricht. Aus diesen Gründen ist das Ziel der Label-Chain nicht eine blosse Rückverfolgbarkeit, sondern einen faireren und transparenteren Handel mit zertifizierten Nahrungsmittel Label-übergreifend zu ermöglichen

Feasibility study of advanced focused cardiac measurements within the emergency department

Abstract Background This study aims to compare the increased time needed to perform advanced focused cardiac measurements in the emergency department, including diastolic heart failure evaluation via E/E′, and cardiac output with LVOT/VTI. Patients with pertinent cardiopulmonary symptoms in the emergency department had a focused cardiac ultrasound performed by the emergency department ultrasound team. The ability to obtain basic cardiac windows, evaluate for effusion, systolic ejection fraction, and right-sided heart pressures were recorded. Advanced measurements, along with time to obtain all images and the training level of the provider, were recorded. Results Fifty-three patients were enrolled. Basic focused cardiac windows were able to be obtained in 80% of patients. The average 4-window focused cardiac ultrasound took 4 min and 49 s to perform. Diastolic measurements were able to be obtained in 51% of patients, taking an average of 3 min and 17 s. Cardiac output measurements were able to be obtained in 53% of patients, taking an average of 3 min and 8 s. Conclusion The ability to obtain these images improved with increasing level of training. Performing both cardiac output and diastolic measurements increased the time with bedside ultrasound by 6 min and 25 s, and were able to be obtained in slightly over half of all ED patients.https://deepblue.lib.umich.edu/bitstream/2027.42/143847/1/13089_2018_Article_93.pd

Association of a longitudinal, preclinical ultrasound curriculum with medical student performance

Abstract Introduction Point-of-care ultrasound (US) is used in clinical practice across many specialties. Ultrasound (US) curricula for medical students are increasingly common. Optimal timing, structure, and effect of ultrasound education during medical school remains poorly understood. This study aims to retrospectively determine the association between participation in a preclinical, longitudinal US curriculum and medical student academic performance. Methods All first-year medical students at a medical school in the Midwest region of the United States were offered a voluntary longitudinal US curriculum. Participants were selected by random lottery. The curriculum consisted of five three-hour hands on-sessions with matching asynchronous content covering anatomy and pathologic findings. Content was paired with organ system blocks in the standard first year curriculum at our medical school. Exam scores between the participating and non-participating students were compared to evaluate the objective impact of US education on performance in an existing curriculum. We hypothesized that there would be an association between participation in the curriculum and improved medical student performance. Secondary outcomes included shelf exam scores for the surgery, internal medicine, neurology clerkships and USMLE Step 1. A multivariable linear regression model was used to evaluate the association of US curriculum participation with student performance. Scores were adjusted for age, gender, MCAT percentile, and science or engineering degree. Results 76 of 178 students applied to participate in the curriculum, of which 51 were accepted. US curriculum students were compared to non-participating students (n = 127) from the same class. The US curriculum students performed better in cardiovascular anatomy (mean score 92.1 vs. 88.7, p = 0.048 after adjustment for multiple comparisons). There were no significant differences in cumulative cardiovascular exam scores, or in anatomy and cumulative exam scores for the gastroenterology and neurology blocks. The effect of US curriculum participation on cardiovascular anatomy scores was estimated to be an improvement of 3.48 points (95% CI 0.78-6.18). No significant differences were observed for USMLE Step 1 or clerkship shelf exams. There were no significant differences in either preclinical, clerkship or Step 1 score for the 25 students who applied and were not accepted and the 102 who did not apply. Conclusions Participation in a preclinical longitudinal US curriculum was associated with improved exam performance in cardiovascular anatomy but not examination of other cardiovascular system concepts. Neither anatomy or comprehensive exam scores for neurology and gastrointestinal organ system blocks were improved.http://deepblue.lib.umich.edu/bitstream/2027.42/173623/1/12909_2022_Article_3108.pd
