[Impact of the experience of urological senior physicians in Germany on professional and personal aspects]. / Welchen Einfluss hat die Dauer der Oberarzttätigkeit auf die Berufsausübung und Zufriedenheit urologischer OberärztInnen in Deutschland?

BACKGROUND: Urological senior physicians in Germany are a heterogeneous group with various clinical priorities and career objectives. To date, there are no reliable data concerning the impact of the time span for which senior physicians have been holding their position on professional, personal and position-linked aspects. MATERIAL AND METHODS: The objective of this study was a comparative analysis of perspectives, private and professional settings, specific job-related activities and individual professional goals of urological senior physicians in Germany based on their experience in this position assessed as number of years (dichotomised at 8 years as senior physician). As part of a cross-sectional study, a 55-item web-based questionnaire was designed, which was sent via a link to members of a mailing list of the German Society of Urology. The survey was available for urological senior physicians between February and April 2019. Group differences were evaluated using multivariate regression models. RESULTS: 107 of 192 evaluable questionnaires were completed by senior physicians holding this position for less than 8 years (< 8y senior physicians), 85 were completed by senior physicians holding this position for at least 8 years (≥ 8y senior physicians). < 8y senior physicians worked significantly more often at university hospitals (42.1 % vs. 18.8 %, p = 0.002). Overall, 82.4 % of ≥ 8y senior physicians assessed themselves autonomously safe in performing open surgery, compared to 39.3 % among < 8y senior physicians (p < 0.001). No significant differences concerning the self-assessment were found for endourological procedures (94.1 % vs. 87.9 %) and for the overall lower-rated self-assessment concerning laparoscopy (29.4 % vs. 20.6 %) and robotic surgery (14.1 % vs. 10.3 %). Despite the high management responsibility associated with their position, only about one third of participants (34.8 %) had received specific postgraduate education preparing them for managing and executive tasks. CONCLUSION: This study shows significant differences among senior physicians regarding surgical skills depending on the time span they hold their position. Moreover, there is considerable dissatisfaction regarding the development of leadership skills and the preparation for managing tasks. In order to ensure availability of senior staff members for the field of urology in the future, it is important to consider their professional needs and to overcome existing shortcomings by education programs within well-orchestrated human resources development strategies.

Pseudonymization of PHI Items in German Clinical Reports.

We describe the adaptation of a non-clinical pseudonymization system, originally developed for a German email corpus, for clinical use. This tool replaces previously identified Protected Health Information (PHI) items as carriers of privacy-sensitive information (original names for people, organizations, places, etc.) with semantic type-conformant, yet, fictitious surrogates. We evaluate the generated substitutes for grammatical correctness, semantic and medical plausibility and find particularly low numbers of error instances (less than 1%) on all of these dimensions.

Laser ablation inductively coupled plasma mass spectrometry imaging of metals in experimental and clinical Wilson's disease.

Wilson's disease is an autosomal recessive disorder in which the liver does not properly release copper into bile, resulting in prominent copper accumulation in various tissues. Affected patients suffer from hepatic disorders and severe neurological defects. Experimental studies in mutant mice in which the copper-transporting ATPase gene (Atp7b) is disrupted revealed a drastic, time-dependent accumulation of hepatic copper that is accompanied by formation of regenerative nodes resembling cirrhosis. Therefore, these mice represent an excellent exploratory model for Wilson's disease. However, the precise time course in hepatic copper accumulation and its impact on other trace metals within the liver is yet poorly understood. We have recently established novel laser ablation inductively coupled plasma mass spectrometry protocols allowing quantitative metal imaging in human and murine liver tissue with high sensitivity, spatial resolution, specificity and quantification ability. By use of these techniques, we here aimed to comparatively analyse hepatic metal content in wild-type and Atp7b deficient mice during ageing. We demonstrate that the age-dependent accumulation of hepatic copper is strictly associated with a simultaneous increase in iron and zinc, while the intrahepatic concentration and distribution of other metals or metalloids is not affected. The same findings were obtained in well-defined human liver samples that were obtained from patients suffering from Wilson's disease. We conclude that in Wilson's disease the imbalances of hepatic copper during ageing are closely correlated with alterations in intrahepatic iron and zinc content.
