Betrachtet werden die {\"U}bermittlung und Verf{\"u}gbarkeit von Gesundheitsdaten, Gesundheitsregister, die elektronische Patientenakte, Einwilligungsverfahren f{\"u}r die {\"U}bermittlung von Daten und der Zugriff auf Gesundheitsdaten zu Forschungszwecken. Methoden Die Studie basiert auf einer computergest{\"u}tzten Telefonbefragung (Dual-Frame) bei einer Zufallsstichprobe der Bev{\"o}lkerung in Deutschland im Zeitraum 01.-27.06.2022 (n = 1.308). Ergebnisse Der Wissensstand zur {\"U}bermittlung von Gesundheitsdaten an Krankenkassen ist hoch, wohingegen das Vorhandensein zentraler Sterbe-, Impf- und Gesundheitsregister sowie der Zugriff auf Gesundheitsdaten durch behandelnde {\"A}rztinnen und {\"A}rzte {\"u}bersch{\"a}tzt werden. Die Akzeptanz medizinischer Register ist sehr hoch. Die elektronische Patientenakte ist bei der H{\"a}lfte der Bev{\"o}lkerung unbekannt, die Nutzungsbereitschaft ist eher gering ausgepr{\"a}gt; bei der {\"U}bertragung von Daten wird eine Zustimmungsoption bevorzugt, und {\"u}ber achtzig Prozent w{\"u}rden die Daten der elektronischen Patientenakte zur Forschung freigeben. Drei Viertel w{\"u}rden ihre Gesundheitsdaten allgemein zur Forschung freigeben, insbesondere an Universit{\"a}ten in Deutschland, wobei meist Anonymit{\"a}t Bedingung ist. Die Bereitschaft zur Datenfreigabe steigt mit der H{\"o}he des Vertrauens in die Presse sowie in Universit{\"a}ten und Hochschulen, und sie sinkt, wenn ein Datenleck als schwerwiegend erachtet wird. Diskussion und Schlussfolgerung In Deutschland besteht, wie in anderen europ{\"a}ischen L{\"a}ndern, eine große Bereitschaft zur Freigabe von Gesundheitsdaten zu Forschungszwecken. Dagegen ist der Wunsch zur Nutzung der elektronischen Patientenakte eher gering. Ebenso niedrig ist die Akzeptanz einer Widerspruchsoption, die jedoch als Voraussetzung f{\"u}r eine erfolgreiche Einf{\"u}hrung einer elektronischen Patientenakte gilt.

We evaluated the prognostic value of different patterns of invasion (PI) in cervical carcinomas (CX). Methods: Six hundred eleven surgically treated CX (FIGO IB to IIB) were re-evaluated histologically regarding the PI, using a three-level scoring system. Closed PI was defined as cohesive growth with well-delineated (pushing) borders. In finger-like PI the tumor grows in solid cords/trabecles. Highly dissociative growth in small groups or single cells was defined as spray-like PI. Types of PI were correlated to tumor stage, histo-morphologic factors and prognostic outcome. Results: Sixty percent of the tumors showed a spray-like PI, 30\% a finger-like PI and only 7.4\% were of the closed type. Spray-like PI showed a significant correlation with advanced stage disease, lymphovascular space involvement, poorly differentiated tumors and pelvic lymph node metastases. Spray-like PI was accompanied by a reduced 5-year overall survival when compared to the finger-like and closed PI (68.7\% vs. 80.9\% vs. 88.5\%; P=0.0004). The prognostic impact of the PI disappeared in node-positive patients (P=0.06) but persisted in patients without pelvic lymph node disease (P=0.03). In multivariate analysis, using COX regression model, the PI represented as independent prognostic factor. Conclusions: Spray-like PI (i.e., highest degree of tumor cell dissociation) is associated with advanced tumor stages, increased rate of recurrency and a reduced overall survival. In separate analysis of patients with and without lymph node metastases, the impact of PI persisted only in node-negative cases as a prognostic factor.}, subject = {Geb{\"a}rmutterhalskrebs}, language = {en} } @article{HornFischerRaptisetal., author = {Horn, Lars-Christian and Fischer, Uta and Raptis, Georgios and Bilek, Karin and Hentschel, Bettina}, title = {Tumor size is of prognostic value in surgically treated FIGO stage II cervical cancer}, series = {Gynecologic Oncology}, volume = {107}, journal = {Gynecologic Oncology}, number = {2}, doi = {10.1016/j.ygyno.2007.06.026}, pages = {310 -- 315}, abstract = {Objectives Tumor size is a well recognized prognostic factor in early stage cervical carcinoma (CX). However, limited knowledge exists about the value of tumor size in surgically treated CX with extrauterine extension. Methods 245 cases of local advanced CX (FIGO stage IIA and IIB) who received upfront surgery were evaluated regarding tumor size, regarding the prediction of pelvic lymph node involvement and recurrence free and overall survival during a median follow-up time of 54 months (95\% CI 45.4-62.6 months). Tumors larger than 4 cm were defined as bulky stage disease. Results Bulky disease was seen in 46.1\% (113/245). 60.2\% of these patients showed pelvic lymph node involvement, compared to 42.4\% (56/132) in non-bulky tumors (p = 0.006; odds ratio: 2.2 [95\% CI: 1.3-3.6]). Patients with bulky tumors showed an increase of recurrent disease (40.2\% vs. 28.0\%; p = 0.045). The relative risk for recurrent disease was 1.97 (95\% CI: 1.3-3.0). The 5-year overall survival rate was significantly lower (67.7\% [95\% CI: 58.2-74.8] vs. 49.5\% [95\% CI: 36.8-59.1]; p = 0.0015). In multivariate analysis, tumor stage, pelvic lymph node involvement and maximal tumor size were independent prognostic factors. Conclusions The results suggest that tumor size, defining bulky disease as tumors larger than 4 cm, is of prognostic impact also in FIGO stage II cervical carcinomas. A revised FIGO/TNM classification system similar to the subgrouping of stage IB CX is recommended for stage II using a cut-off value of 4 cm as discriminator: stage IIA1 and stage IIB1 for tumors with ≤ 4 cm and IIA2 and IIB2 for tumors > 4 cm (i.e. bulky disease).}, subject = {Geb{\"a}rmutterhalskrebs}, language = {en} } @inproceedings{HoehRaptis, author = {H{\"o}h, H. and Raptis, Georgios}, title = {Applications of the Erbium: YAG Laser in Ophthalmology - Cataracta-, Glaukoma-, Eyelid-Surgery and pars plana Vitrectomy}, abstract = {Recent developments in lasers have provided us the possibility of laser ocular surgery.

This paradigm shift also affects eHealth applications. Digital identities in nation-wide eHealth infrastructures are often realized via smart cards, which however, do not support mobile applications well. In this paper we propose a concept of a mobile eID for eHealth based on smartphones with embedded secure hardware, an mobile authenticator app and an account manager as well as an Identity Provider (IdP) as backend services. The practical applicability of the concept is shown using the example of the German eHealth infrastructure. Our method generates a cryptographic key pair in secure hardware on the user's smartphone, registers it on the IdP and uses it to authenticate on the IdP. The security of the private key and the integrity of the smartphone is also validated and attestated. The user's established smartcard-based identity "Electronic Health Card" (EHC) forms the trust anchor. To authenticate against specialist eHealth apps the IdP issues standard-compliant OAuth2.0/OIDC tokens with a limited period of validity. Furthermore, in our security analysis we demonstrate that based on specific security requirements for smartphones and operating systems, at least the eIDAS security level "substantial" related to the technical security aspects of the system can be achieved. On the basis of this research German legislation was adjusted and "digital identities" supplementary to the smartcard-based EHC will be issued from 2023 in the German eHealth infrastructure.}, language = {en} } @misc{Raptis, author = {Raptis, Georgios}, title = {Vernetzung und ubiquit{\"a}re Informationsverarbeitung - technisch-organisatorischer Datenschutz in der Arztpraxis}, series = {2.

In this paper, we focus on the effects of the choice architecture on the decision for the adoption ofnational EHRs. Our study aims to link influences on human behaviour through nudging with the adoption of EHRs to inves-tigate how choice architects can facilitate the adoption of national information systems. Methods: We employ a qualitative explorative research design, namely the case study method. Using theoretical sampling,we selected four cases (i.e., countries) for our study: Estonia, Austria, the Netherlands, and Germany. We collected and ana-lyzed data from various primary and secondary sources: ethnographic observation, interviews, scientific papers, homepages,press releases, newspaper articles, technical specifications, publications from governmental bodies, and formal studies. Results: The findings from our European case studies show that designing for EHR adoption should encompass choice archi-tecture elements (i.e., defaults), technical elements (i.e., choice granularity and access transparency), and institutional ele-ments (i.e., regulations for data protection, information campaigns, and financial incentives) in combination.

Im Gegensatz zu den erblich bedingten Tumorerkrankungen sind die Kenntnisse zur Bedeutung famili{\"a}rer Faktoren bei den sog. sporadischen Tumoren, insbesondere beim Zervixkarzinom (CX) begrenzt. Material und Methode: Patientinnen des CX-Registers der Universit{\"a}ts-Frauenklinik wurden retrospektiv bez{\"u}glich der Familienanamnese (FA) analysiert. Als positive FA wurde eine maligne Tumorerkrankung bei einem oder mehreren Verwandten ersten Grades definiert. Es wurde unterschieden, ob es sich um Zervixkarzinome, andere gyn{\"a}kologische Malignome (außer Mammakarzinom) oder eine extragenitale Lokalisation handelte. Diese Daten wurden zum Erkrankungsalter und zum Nachweis pelviner Lymphknotenmetastasen in Beziehung gesetzt. Ergebnisse: 159/737 Frauen (21,6 \%) wiesen eine positive FA auf. In 10,7 \% der F{\"a}lle war mehr als ein Verwandter ersten Grades erkrankt; bei 6,9 \% Angeh{\"o}rige ersten und zweiten Grades. Weibliche Verwandte ersten Grades von 42 Frauen wiesen Malignome des weiblichen Genitaltraktes (außer CX) auf. In 6,9 \% waren die Mutter und/oder die Schwester an einem Zervixkarzinom erkrankt. Das Durchschnittsalter der Patientinnen mit positiver Familienanamnese (FA) unterschied sich nicht von dem derjenigen mit leerer FA, wohl aber bei getrennter Betrachtung nach der Tumorlokalisation. Bez{\"u}glich des Tumorstadiums (pTNM) und der Zahl der Patientinnen mit histologisch nachgewiesenen pelvinen Lymphknotenmetastasen bestand kein Unterschied. Schlussfolgerungen: Die bisherigen Ergebnisse deuten auch beim Zervixkarzinom auf eine famili{\"a}re Belastung hin. Dabei existieren offenbar Familien, in denen mit HPV-assoziierte Pr{\"a}kanzerosen bzw. Tumoren vermehrt auftreten. Besonders gef{\"a}hrdet sind Patientinnen, deren weibliche Anverwandte ersten Grades bereits an einer zervikalen Pr{\"a}kanzerose (besonders CIN III) oder einem invasiven CX erkrankt sind. Diese Frauen sollten einem engmaschigen Screening unterzogen werden.}, subject = {Geb{\"a}rmutterhalskrebs}, language = {de} } @article{HornRaptisNenning, author = {Horn, Lars-Christian and Raptis, Georgios and Nenning, Hans}, title = {DNA cytometric analysis of surgically treated squamous cell cancer of the uterine cervix, stage pT1b1-pT2b}, series = {Analytical and quantitative cytology and histology}, volume = {24}, journal = {Analytical and quantitative cytology and histology}, number = {1}, pages = {23 -- 29}, abstract = {Objective: To determine the utility of DNA content and DNA-related variables of proliferative activity regarding prognosis in cervical cancer. Study design: DNA image (ICM) andflow cytometry (FCM) were performed to determine the DNA index (DI), 5c-exceeding rate (5c-ER), S-phase fraction (SPF) and proliferation index (PI) in 163 patients with surgically staged pT1b1-pT2b squamous cell cancer of the uterine cervix and treated with primary radical hysterectomy. ICM was performed on imprint cytology, obtained from fresh tumor tissue, which was also used for FCM. Results were analyzed using the chi2 test and Cox regression analysis for risk of pelvic lymph node involvement, tumor recurrence and recurrence-free survival (RFS). Results: ICM was performed on all 163 and FCM on 133 samples. One-third of the tumors showed DNA aneuploidy. Analysis demonstrated prognostic significance of a DI > or = 1.70, with a (70:30) 2.3-fold risk of recurrence (P=.024) and reduced RFS of 10 months (P=.003) in cases of DI > or = 1.70. A high 5c-ER > 11\% was associated with pelvic lymph node involvement and decreased RFS (P < or = .04). Significantly more relapses were found in tumors with SPF > 12\% (70.8\% vs. 29.2\%, P=.007). RFS was markedly reduced in tumors with high SPF (52.3 vs. 61.1 months, P=.011). Low proliferative tumors (PI<25\%) were associated with lower stage (P=.036) and increased RFS (61.2 vs. 47.1 months, P=.028). In multivariate analysis of clinicopathologic variables (pT category, nodal status, lymphovascular space involvement) and DNA related variables, pelvic lymph node involvement was the only significant predictor of RFS. In patients with nodal involvement, tumors with DI >1.70 were associated with lessfavorable outcomes. Conclusion: DNA-related variables of cell cycle analysis were valuablefor predicting prognosis in cervical cancer patients. Tumors with DI>1.70, 5c-ER >11\% and high proliferative activity (SPF>12\%, PI>25\%) represent a subgroup with a poor prognosis.}, subject = {Geb{\"a}rmutterhals}, language = {en} } @article{HornPippigRaptisetal., author = {Horn, Lars-Christian and Pippig, S. and Raptis, Georgios and Fischer, Uta and K{\"o}hler, U. and Hentschel, Bettina and Martin, Rosemarie}, title = {Clinical relevance of urokinase-type plasminogen activator and its inhibitor type-1 (PAI-1) in squamous cell carcinoma of the uterine cervix}, series = {Australian and New Zealand Journal of Obstetrics and Gynaecology}, volume = {42}, journal = {Australian and New Zealand Journal of Obstetrics and Gynaecology}, number = {4}, doi = {10.1111/j.0004-8666.2002.00385.x}, pages = {385 -- 388}, abstract = {Objective The expression of uPA and PAI-1 as parameters of tumour-associated proteolysis has been implicated in the process of tumour cell invasion and the metastatic process. However, there is limited information on the impact of these parameters in cervical carcinoma. Methods Quantitative levels for uPA (n = 114) and PAI-1 (n = 103) were researched in operatively treated, surgically staged squamous cell cancer of the uterine cervix, using an ELISA-technique. Results were assessed regarding their impact in predicting pelvic lymph nodes metastases, tumour recurrence rate and recurrence free survival (RFS) using uni- and multivariate analysis. Results Median levels of both parameters were significantly higher in tumour tissue than in normal cervical tissue (p < 0.001). Detection of uPA gave no useful prognostic information. PAI-1 concentration showed a positive correlation with advanced tumour stage (p = 0.008), but no significant correlation with nodal status (pN0: 2.6 vs. pN1: 4.0 ng/mg protein; p = 0.092). Using a cut-off level of 2.4 ng/mg protein, patients with elevated PAI-1 levels demonstrated reduced RFS (45.9 versus 52.9 months; p = 0.1). Multivariate analysis, including nodal status, tumour stage, lymphovascular space involvement and grading failed to demonstrate any prognostic impact of uPA and PAI-1. Conclusions The results indicate, that PAI-1 expression is of some prognostic impact in cervical cancer, indicating an association of elevated PAI levels with local tumour progression and reduced recurrence-free survival.}, subject = {Plasminogen human-Aktivator}, language = {en} } @inproceedings{Raptis, author = {Raptis, Georgios}, title = {Ein Verfahren zur L{\"o}sung des Problems der kryptographischen Langzeitsicherheit medizinischer Daten, die in einer Infrastruktur gespeichert werden}, series = {BIOSIG-Konferenz 2007, Darmstadt}, booktitle = {BIOSIG-Konferenz 2007, Darmstadt}, abstract = {Medizinische Daten, die - wie derzeit f{\"u}r die Telematik-Infrastruktur nach \S291a SGB V spe-zifiziert - auch außerhalb der physischen Kontrolle der Eigent{\"u}mer oder Ersteller (also z.B. außerhalb von Arztpraxen oder Klinken) auf Servern kryptographisch verschl{\"u}sselt gespeichert werden, m{\"u}ssen sehr lange vertraulich bleiben.
