- Abstract
Background: Clinical trials have shown that cenobamate (CNB) is an efficacious and safe anti-seizure medication (ASM) for drug-resistant focal epilepsy. Here, we analyzed one of the largest real-world cohorts, covering the entire spectrum of epilepsy syndromes, the efficacy and safety of CNB, and resulting changes in concomitant ASMs., Methods: We conducted a retrospective observational study investigating CNB usage in two German tertiary referral centers between October 2020 and June 2023 with follow-up data up to 27 months of treatment. Our primary outcome was treatment response. Secondary outcomes comprised drug response after 12 and 18 months, seizure freedom rates, CNB dosage and retention, adverse drug reactions (ADRs), and changes in concomitant ASMs., Results: 116 patients received CNB for at least two weeks. At 6 months, 98 patients were eligible for evaluation. Thereof 50% (49/98) were responders with no relevant change at 12 and 18 months. Seizure freedom was achieved in 18.4% (18/98) at 6 months, 16.7% (11/66), and 3.0% (1/33) at 12 and 18 months. The number of previous ASMs did not affect the seizure response rate. Overall, CNB was well-tolerated, however, in 7.7% (9/116), ADRs led to treatment discontinuation. The most frequent changes of concomitant ASMs included the discontinuation or reduction of sodium channel inhibitors, clobazam reduction, and perampanel discontinuation, while brivaracetam doses were usually left unchanged., Conclusions: CNB proved to be a highly effective and generally well-tolerated ASM in patients with severe drug-resistant epilepsy, comprising a broad array of epilepsy syndromes beyond focal epilepsy., (© 2024.

- Abstract
Purpose: Older employees are often thought to be vulnerable to negative effects of information and communication technology (ICT). Our study aims to examine associations between work-related ICT exposure (i.e. ICT use or digital work intensification), physical health, mental health and work ability (WA). We examine whether these associations are modified by socio-economic position (SEP)., Methods: We analysed cross-sectional data from 3180 participants (born in 1959 and 1965) in wave 3 of the representative German lidA cohort study. We performed hierarchical multiple regression to assess the distinct associations of ICT use and digital work intensification with mental and physical health and WA. We stratified analyses by SEP and controlled for age, sex, and digital affinity., Results: 92% of participants reported ICT use at work. Almost 20% reported high levels of digital work intensification, while a similar proportion did not experience digital work intensification. In bivariate analyses, ICT use by itself was not significantly associated with mental health or WA in the total sample or when stratified. Digital work intensification displayed negative associations with mental health and WA. In hierarchical multiple regressions, digital work intensification showed consistently negative associations with mental health and work ability of similar strength across SEP., Conclusion: Our results suggest that ICT use, per se, does not negatively impact older workers. Digital work intensification may be associated with worse mental health and work ability. Research on health and social implications of work-related ICT should differentiate patterns of ICT exposure and assess modifications by SEP to better gauge the ambiguous effects of ICT.

- Abstract
Preventable chronic diseases account for the greatest burden in the German health system and statutory health insurance (SHI) funds play a crucial role in implementing and financing prevention strategies. On the contrary, the morbidity-based scheme to distribute financial resources from the Central Reallocation Pool among the different sickness funds may counteract efforts of effective prevention from an economic perspective. We assessed financial impacts of prevention from a sickness funds perspective in a retrospective controlled study. Claims data of 6,247,275 persons were analyzed and outcomes between two propensity-matched groups (n = 852,048) of prevention users and non-users were compared in a 4-year follow-up. Using a difference-in-differences approach, we analyzed healthcare expenditures, the development of morbidity, financial transfers from the Central Reallocation Pool, and contribution margins. The group of prevention users develops less morbidity (incidences and disease aggravations) compared to the control group. Healthcare expenditures increase in both groups within 4 years, whereas the increase is lower for prevention users compared to non-users (€568.04 vs. €640.60, p < 0.0001). Taking morbidity-based financial transfers into account, the decrease in contribution margins is stronger for prevention users (- €188.44 vs. - €138.73, p < 0.0001). This study demonstrates an economic disincentive from a sickness funds' perspective. In the semi-competitive SHI market, sickness funds will be discouraged from effective prevention strategies if investments are not worth it financially. Their efforts and knowledge are, however, crucial for joint action to foster prevention over cure in the health system.

- Abstract
Purpose: This study aimed to find out more about factors that hinder physicians' careers, especially with regard to gender differences, and which future working conditions they would prefer., Methods: In an online survey, members of the professional societies of Hematology and Oncology in Germany, Austria and Switzerland were asked to rate factors that might hinder or facilitate their professional career. Data analysis included χ
2 -tests, t tests and analyses of variance., Results: 469 physicians participated (61% female, response rate 9.1%). 40% of the participants experience a lack of compatibility between family life and career. Female physicians with children living in their household especially feel restricted in their professional development. The most preferred conditions for improving compatibility were flexible working hours (72%), opportunities to work in home office (71%), better opportunities for specialist training (51%) and enabling managerial activities on a part-time basis (73%). Both female and male physicians would like fathers to be encouraged to take parental leave to the same extent as mothers (50%). They would, e.g., like to see more flexible drop-off and pickup times for children (71%) and more childcare options offered by their employer (61%)., Conclusion: Results suggest various options for promoting compatibility of family life and work, e.g., by family-friendly working time models and part-time offers breaking with traditional role models. Managerial positions might be offered on a regular part-time basis. Structured qualification programs could enable the compatibility of clinical work, research and family life. Childcare services should preferably be provided in line with existing needs., (© 2022. The Author(s), under exclusive licence to Springer-Verlag GmbH Germany, part of Springer Nature.)- Published

- Abstract
As the German population is continually aging and the majority of older adults still wish to 'age in place', the need for informal care provided by family and friends will correspondingly continue to increase. In addition, while the need for formal (professional) care services is also likely to increase, the supply already does not meet the demand in Germany today. The aim of our study is the elicitation of people's willingness to provide informal care by means of a discrete choice experiment. The self-complete postal survey was disseminated to a random sample of the German general population in Lower Saxony. Data cleansing resulted in a final sample size of 280 participants. A conditional logit and a latent class model were estimated. All attributes were judged as highly relevant by the respondents. The results revealed that an increase in the care hours per day had the greatest negative impact overall on the willingness to provide informal care in our sample. The marginal willingness-to-accept for 1 h of informal care was €14.54 when having to provide informal care for 8 h in reference to 2 h per day. This value is considerably higher than the national minimum wage of €9.82. A three-class latent class model revealed preference heterogeneity. While a monetary compensation is often discussed to increase the willingness and availability of informal care in a country, our results show that this statement could not be generalized within our entire sample., (© 2022.

- Abstract
Purpose: The International Abstract(s) of Surgery (IAS) was a monthly supplement to Surgery, Gynecology & Obstetrics (SG&O, later Journal of the American College of Surgeons) from 1913-1994, approximately equal in size to the journal itself. It followed the example of the Zentralblatt für Chirurgie (ZblCh), which had been compiling abstracts of the current world surgical literature since 1874 (but in the German language). This article seeks to review the relationships of these surgical abstract journals in historical context., Methods: Citations in the IAS were systematically sampled for 1913-1990, and in the ZblCh and other American and German surgical publications for 1905-1940. Changes in the proportions of citations by language category were tabulated over time and related to concurrent international events and the publication histories of the sampled journals., Results: German-language citations were most frequent until the First World War, even in America. They subsequently became less frequent in America, but remained dominant in Germany. Articles in French or other languages were occasionally cited by Americans, but in German publications, they were cited as frequently as those in English. Contemporary observations from this time confirm that the American literature was being disregarded by most German surgeons. Since the Second World War, surgical publications have become predominantly English-language, even in Germany, and printed abstract compilations have become irrelevant., Conclusions: The history of the IAS and ZblCh reflects world events of the early twentieth century, the isolation and decline of German scientific leadership, the rise of American surgery, and the transition from a multilingual print-based era to one where scientific communication is primarily electronic and in English., (© 2022.

- Abstract
Objective: Due to recent trends such as globalization and digitalization, more and more employees tend to have flexible working time arrangements, including boundaryless working hours. The aim of this study was to investigate the relationships of various aspects of boundaryless working hours (overtime, Sunday work, and extended work availability) with employees' state of recovery. Besides, we examined the mediating and moderating role of recovery experiences (psychological detachment, relaxation, mastery, and control) in these relationships., Methods: We used data from 8586 employees (48% women; average age of 48 years) who took part in the 2017 BAuA-Working Time Survey, a representative study of the German working population. Regression analyses were conducted to test main effects as well as mediation and moderation., Results: Overtime work, Sunday work, and extended work availability were negatively related to state of recovery. Psychological detachment mediated these relationships. Furthermore, we found that relaxation and control mediated the association between extended work availability and state of recovery. However, no relevant moderating effects were found., Conclusions: Altogether, our findings indicate that various aspects of boundaryless working hours pose a risk to employees' state of recovery and that especially psychological detachment is a potential mechanism in these relationships. In addition, the results suggest that a high level of recovery experiences cannot attenuate these negative relationships in leisure time. Therefore, employers and employees alike should try to avoid or minimize boundaryless working hours., (© 2021. The Author(s).)

- Abstract
Background: Survey by the commission for cross-sectoral ophthalmology, as a joint commission of the German Ophthalmological Society (DOG) and the Professional Association of German Ophthalmologists (BVA) on the effects of the SARS-CoV‑2 pandemic on ophthalmological patient care in Germany., Methods: Online-based survey., Results: A total of 1190 questionnaires were (partly) answered. With respect to outpatient care and consultations from 15 March to 15 April 2020, a total of 69 (5.8%) participants indicated unlimited, 756 (63.5%) reduced and 330 (27.7%) emergency care only, independent of the type of institution. Outpatient surgery was restricted to emergency surgery in 68% of clinics, 42.0% of inpatient wards, 45.0% of surgical medical care centers and group practices and 33.0% of private practices. Inpatient procedures were limited to emergency care in 75.0% of inpatient wards and in 71.0% of clinics. With the exception of endophthalmitis (+8.2%), the number of urgent indications and emergencies declined: retinal detachment (-34.8%), perforating eyeball injuries (-7.3%), acute glaucoma (-17.8%), central retinal artery occlusion and anterior ischemic optic neuropathy (-31.0%), others (-30.9%), penetrating keratoplasty and amniotic membrane transplantation (-59.1%). Institutional or professional policy requirements (76.0%) and appointment cancellation by patients (84.0%) were the most common reasons for limitations in ophthalmic patient care., Conclusion: The initial phase of the pandemic was characterized by a massive reduction in non-urgent conservative and surgical treatment that affected all areas of ophthalmology. Due to intensive care capacities required for COVID-19 patients, inpatient treatment was largely restricted to emergencies. Treatment of ophthalmological patients, including ocular emergencies and urgent treatment, was maintained across all sectors with a (considerable) decrease in the number of cases even in these groups., (© 2021.

- Abstract
Introduction: Neck dissection (ND) is a surgical procedure addressing cervical lymph nodes and metastases in patients with oral squamous cell carcinoma (OSCC). The aim of this study was to analyze clinical decisions regarding indications and variations of ND in Oral and Maxillofacial Surgery (OMFS) in Germany., Material and Methods: A nationwide survey of the German Association of Oral and Maxillofacial Surgery was performed using dynamic online questionnaires including 38 questions. Data about oncological centers, case numbers, and staging procedures were collected. Relevant aspects, such as inclusion of level IIb and levels IV and V to ND, uni- vs. bilateral ND, and the influence of extra-nodal extension (ENE) of metastases on extension of ND were evaluated., Results: Eighty-four OMFS of university and non-university hospitals participated in the study (responding rate 21.4%). Sixty-six (78.57%) stated to work at certified cancer centers and 53.57% of the hospitals treated between 50 and 100 OSCC cases per year. CT and/or MRI of the head and neck was performed in most of the staging procedures. Level IIb was included by 71 (93.42%) of the participants in selective ND. Levels IV and V were included by 53 (69.74%) in node-positive neck. In solitary ipsilateral metastases (ENE-), 49 participants (62.82%) stated to perform exclusively an ipsilateral ND and 40 (51.95%) stated to perform only an ipsilateral ND in ENE+., Conclusion: This study demonstrated a high rate of certified cancer centers in Germany showing differences regarding staging procedures, indications, and extension of ND, especially in increasingly complex cases., Clinical Relevance: Clinical decisions regarding ND are dependent on case-individual aspects and must be decided individually.

- Abstract
Virtual reality (VR) is increasingly gaining importance as a valuable methodical tool for psychological research. The greatest benefit of using VR is generating rich, complex and vivid, but still highly controllable settings. As VR has been found to elicit lifelike psychophysiological and emotional responses, we examined by means of a height exposure whether VR resembles physical reality to the necessary degree to constitute a suitable framework for investigating real-life behavior in a controlled experimental context. As hypothesized, participants behaved in VR exactly as would be appropriate in a real environment: Being exposed to great height, participants walked significantly slower across a virtual steel girder construction protruding from a high-rise building as compared to participants who traversed the very same construction on the ground level. In the height condition, this realistic behavior could be predicted on basis of the participants' trait anxiety. Aligned with the behavioral responses, they showed realistic psychophysiological responses, i.e., an elevated heart rate when exposed to height. Interestingly, participants of the height condition reported a greater sense of presence, which indicates that emotions have an elevating effect on presence. As a conclusion, our findings provide further evidence that VR evokes lifelike responses at both behavioral and psychophysiological level and therefore increases ecological validity of psychological experiments.

- Abstract
Objective: The aim of this prospective study was to examine employer changes among older workers and to relate them to psychosocial work factors, health, and work ability. Four groups of employees as elaborated by Hom et al. (2012) were distinguished: Enthusiastic leavers (EL), reluctant leavers (RL), enthusiastic stayers (ES), and reluctant stayers (RS)., Methods: Repeated Measures ANOVA analyses were based on data from the second and third waves (2014, 2018) of the German lidA Cohort Study, a representative study of employees born in 1959 or 1965., Results: The largest proportion of participants was ES (73.3%), 13.2% stayed with their employer although they would have preferred to leave (RS). 7.1% changed employer between 2014 and 2018 voluntarily (EL), 6.4% involuntarily (RL). Analyses confirmed that the four groups already differed in 2014 in terms of health, work ability, and psychosocial work factors and that these outcomes change in different characteristic patterns over time. Most outcomes improved substantially following the change among EL. RS already reported poor outcomes in 2014 and exhibited a further deterioration while staying at the undesired workplace., Conclusion: Our findings indicate that an employer change is followed by improvements of work, health, and work ability. We conclude that an inclusive labor market policy for older workers allowing for high job mobility may have the potential to contribute to considerable improvements of workers' individual working conditions, health, and work ability, thereby increasing the work participation. Also, the considerable group of RL requires increased political and scientific attention.

- Abstract
Objective: In 2018 Germany had the lowest rate of post-mortem organ donation in the Eurotransplant network. Healthcare trainees and students will be important advisors on organ donation for patients in the future. This study aimed to examine 1) attitudes and knowledge about post-mortem organ donation, 2) how past transplantation scandals have affected those attitudes and 3) how satisfied respondents were with the knowledge provided on the courses., Methods: A cross-sectional study was conducted between 20 March and 8 July 2019 at a university hospital and nursing schools in Berlin and Potsdam, Germany. Study participants were 209 medical students, 106 health sciences students and 67 trainee nurses., Results: Of the respondents 29.3 and 50.8% knew the tasks of the German Organ Transplantation Foundation and Eurotransplant, respectively. All brain death questions were correctly answered by 56.3% of the medical students, 25.7% of the health sciences students and 50.9% of the trainee nurses (Fisher's exact test p < 0.001, Cramer's V = 0.242). Transplantation scandals had damaged attitudes towards organ donation for 20.7% of the medical students, 33.3% of the health sciences students and 13.6% of the trainee nurses (χ
2 -test p = 0.001, Cramer's V = 0.164). Asked whether post-mortem organ donation was sufficiently addressed in their courses, 39.5% of the medical students, 60.4% of the health sciences students and 51.9% of the trainee nurses said this was not or tended not to be the case (Kruskal-Wallis H-test p < 0.001, Spearman's rho r = -0.112)., Conclusion: Given the knowledge gaps identified and the respondents' dissatisfaction with the knowledge they received, organ donation should be better integrated into curricula and training programs.- Published

- Abstract
Per- and polyfluoroalkyl substances (PFAS) are known as persistent and bioaccumulative chemicals. The present paper describes the analysis of 969 human blood samples collected in South Germany aiming to determine whether there are statistic significant differences in internal PFAS burden between three regions with known PFAS releases in the environment (study regions) and three regions without known PFAS releases in the environment (control regions). Nine environmental relevant PFAS were analyzed, including the perfluorooctanoic acid (PFOA) substitute 3H-perfluoro-3-[(3-methoxy-propoxy)propanoic acid] ammonium salt (ADONA). We found that concentrations of PFOA and perfluorooctane sulfonate (PFOS) were higher than for all other PFAS in all of the six regions, but all medians of PFOA (between 0.8 and 0.9 ng/ml for the study and control regions) and PFOS (between 1.3 and 1.5 ng/ml for the study regions and between 1.4 and 1.5 ng/ml for the control regions) were below the human biomonitoring values (HBM) I for PFOA (2 ng/ml) und for PFOS (5 ng/ml) derived by the German HBM Commission. Concentrations of ADONA were below the limit of quantification in all samples. Minor differences were observed in PFAS blood levels between study and control regions. Especially for PFOS and PFOA the medians for women are slightly lower compared to men. In summary, individuals living in regions with known environmental PFAS contaminations show no higher internal PFAS exposure to controls and in comparison to other studies in the literature., (© 2024.

- Abstract
Purpose: The healthcare system is responsible for around 5% of CO
2 emissions globally and in Germany. So far, there are no data on the amount of waste from dry eye disease (DED) therapy in ophthalmology. The aim of this project was to evaluate the amount and type of waste from single- and multi-dose units (SDU/MDU) generated by eyedrops used to treat DED in Germany., Methods: The net waste weight (outer/inner packaging, instruction leaflet, empty container) from factory-sealed products was determined using a precision scale. Based on prescription data from PharMaAnalyst, a database of medical prescriptions from over 70 million patients in Germany, the total annual waste volume for 2016-2021 and the net weight of a 30-day treatment were calculated., Results: The total annual waste volume increased significantly (p < 0.0001) from 7.13 tons in 2016 to 20.64 tons in 2021. A 30-day treatment with MDUs (without/with filter) results in a significantly lower mean waste volume (paper: SDU 24.3 ± 18.7 g; MDU 4.8 ± 1.7 g/8.8 g ± 1.7 g; SDU/MDU p = 0.0003, with filter p = 0.0034; plastic: SDU 35.0 ± 4.0, MDU 6.6 ± 0.7 g/ 15.1 g ± 5.8 g, SDU/MDU p < 0.0001, with filter p < 0.0001)., Conclusion: Prescription-based treatment of DED in Germany causes an increasing and substantial waste volume. The use of SDUs is considerably more resource-intensive than MDUs. Due to the large and rising number of patients suffering from DED improvements in packaging could considerably reduce the CO2 footprint of DED treatment., (© 2024. The Author(s).)- Published

- Abstract
In this paper, we use unique health record data that cover outpatient care and the associated costs to quantify the health care costs of a sizable increase in the retirement age in Germany. For the identification, we exploit a sizable cohort-specific pension reform which abolished an early retirement program for all women born after 1951. Our results show that health care costs significantly increase by about 2.9% in the age group directly affected by the increase in the retirement age (women aged 60-62). We further show that the cost increase is mainly driven by the following specialist groups: Ophthalmologists, general practitioners (GPs), neurology, orthopedics, and radiology. While the effects are significant and meaningful on the individual level, we show that the increase in health care costs is modest relative to the positive fiscal effects of the pension reform. Specifically, we estimate an aggregate increase in the health costs of about 7.7 million euro for women born in 1952 aged 60-62 which amounts to less than 2% of the overall positive fiscal effects of the pension reform., (© 2022.

- Abstract
Purpose: The evidence-based (S3) guideline "Adult Soft Tissue Sarcomas" (AWMF Registry No. 032/044OL) published by the German Guideline Program in Oncology (GGPO) covers all aspects of sarcoma treatment with 229 recommendations. Representatives of all medical specialties involved in sarcoma treatment contributed to the guideline. This paper compiles the most important recommendations for surgeons selected by delegates from the surgical societies., Methods: A Delphi process was used. Delegates from the surgical societies involved in guideline process selected the 15 recommendations that were most important to them. Votes for similar recommendations were tallied. From the resulting ranked list, the 10 most frequently voted recommendations were selected and confirmed by consensus in the next step., Results: The statement "Resection of primary soft tissue sarcomas of the extremities should be performed as a wide resection. The goal is an R0 resection" was selected as the most important term. The next highest ranked recommendations were the need for a preoperative biopsy, performing preoperative MRI imaging with contrast, and discussing all cases before surgery in a multidisciplinary sarcoma committee., Conclusion: The evidence-based guideline "Adult Soft Tissue Sarcomas" is a milestone to improve the care of sarcoma patients in Germany. The selection of the top ten recommendations by surgeons for surgeons has the potential to improve the dissemination and acceptance of the guideline and thus improve the overall outcome of sarcoma patients., (© 2023.

- Abstract
When healthcare interventions prolong life, people consume medical and non-medical goods during the years of life they gain. It has been argued that the costs for medical consumption should be included in cost-effectiveness analyses from both a healthcare and societal perspective, and the costs for non-medical consumption should additionally be included when a societal perspective is applied. Standardized estimates of these so-called future costs are available in only a few countries and the impact of inclusion of these costs is likely to differ between countries. In this paper we present and compare future costs for five European countries and estimate the impact of including these costs on the cost-effectiveness of life-prolonging interventions. As countries differ in the availability of data, we illustrate how both individual- and aggregate-level data sources can be used to construct standardized estimates of future costs. Results show a large variation in costs between countries. The medical costs for the Netherlands, Germany, and the United Kingdom are large compared to Spain and Greece. Non-medical costs are higher in Germany, Spain, and the United Kingdom than in Greece. The impact of including future costs on the ICER similarly varied between countries, ranging from €1000 to €35,000 per QALY gained. The variation between countries in impact on the ICER is largest when considering medical costs and indicate differences in both structure and level of healthcare financing in these countries. Case study analyses were performed in which we highlight the large impact of including future costs on ICER relative to willingness-to-pay thresholds., (© 2022. The Author(s).)

- Abstract
This paper contributes to the discussion of whether non-indicated ultrasound examinations of the thyroid gland contribute to overtreatment and excess health care expenditures. Using two sources of claims data from Germany, we analyzed data from patients who underwent a TSH blood test which is the initial diagnostic measure to check for possible presence of thyroid dysfunction. In a matching analysis, we compared health costs of two groups of patients. One consisted of patients who underwent an early thyroid ultrasound that according to medical guidelines-at this point-was probably not indicated. The other group consisted of patients, who underwent no ultrasound examination at all or later in the course of the disease, making probable a correct indication. Both groups were made comparable by the means of a matching procedure. Average thyroid-specific health costs were substantially higher for the first group in the quarter in which the ultrasound examination took place. Some deviation in these specific costs persisted over a substantial period of time, with drug expenditures exhibiting the biggest difference. If, however, total health costs were considered, difference in costs was only found in the initial quarter. We conclude that non-indicated ultrasound examination of the thyroid gland may have some moderate effects on thyroid-specific costs. Yet the data do not suggest that long-lasting overtreatment and excess health expenditures are initiated by non-indicated ultrasound in Germany., (© 2021. The Author(s).)

- Abstract
When Adolf Hitler annexed Austria to the German Reich in 1938, the famous Jewish oral pathologist Bernhard Gottlieb was in great distress. The Viennese university teacher immediately lost his employment and teaching authority and was forced to emigrate.While Gottlieb's exceptional scientific position in oral pathology is well documented, the complex implications of his deprivation of rights and forced emigration in the Third Reich have so far received little attention. Against this background, the present contribution poses the question of the concrete effects of this drastic event on Gottlieb's life and work.In order to clarify this question, Gottlieb's career status, his scientific success up to 1938, the concrete background of his forced emigration, as well as the further course of his life and career in the USA (his immigration country) are scrutinized. In addition, the paper analyzes the extent to which Gottlieb was able to build on his professional career after 1945 and posthumously. The work is based on a thorough analysis of Gottlieb's academic career using archival sources and a re-analysis of the relevant research literature.The study concludes that Gottlieb suffered a severe setback after his emigration. Several reasons played a role. In particular, cultural and age-related adjustment problems, difficult local conditions, and scarce financial resources hampered the seamless continuation of Gottlieb's career in the USA. Only in the last two decades have efforts been made, particularly in the environment of the University of Vienna, to bring Bernhard Gottlieb and his scientific achievements back into collective memory., (© 2020.

- Abstract
Background: Herbert Siegmund (1892-1954) was undoubtedly one of the most influential German pathologists of the 20th century. He received numerous high honors both during the Third Reich and after 1945. He was, among other things, rector of the University of Münster (1943-1945), holder of the Goethe Medal awarded by Hitler (1944), honorary doctor of the University of Cologne (1949), recipient of the Paracelsus Medal (1953), and president of the German Society for Pathology (DGP, 1954). The almost seamless post-war career was possible above all because Siegmund was counted among the politically uninvolved university physicians after 1945. It was not until after the turn of the millennium that this picture cracked., Material and Methods: The article is based on primary sources from the State Archives of Schleswig-Holstein and North Rhine-Westphalia, the University Archives of Münster, the Federal Archives of Berlin, the University Archives of Cologne, and the City Archives of Stuttgart, some of which were evaluated for the first time. Two questions are at the center of this article: (1) To what extent can it be proven that Siegmund benefited from the Nazi state in terms of his career after 1933? (2) Are there indications that he served the Nazi regime and its networks? In addition, we will discuss how Siegmund himself described his role in the Third Reich and whether his statements stand up to critical scrutiny., Results: The paper concludes that Siegmund contributed to valorizing the Nazi system. After 1945, he did not position himself at a critical distance from his activities in the Third Reich; rather, he drew of himself - largely unopposed - the image of a politically blameless scholar., (© 2020.

- Abstract
Like many OECD countries, Germany is currently facing a shortage of long-term care (LTC) workers. This situation is concerning in the context of the ageing of the German population. A potential reason why Germany fails to recruit and retain LTC workers is that LTC jobs are particularly demanding (physical and psychological strain) which may be harmful to health. However, there is a lack of empirical evidence demonstrating this effect. This article fills the gap in the literature by exploring to what extent LTC jobs reduce workers' health over time. We estimate a dynamic panel data model on the German Socio-Economic Panel (v.35; 1984-2018), which allows adressing selection issues into occupations. Our paper provides innovative findings on the impact of LTC occupations on workers' health. We confirm that LTC jobs have a negative impact on self-reported health. Our results have strong policy implications: we emphasize the need to provide sufficient assistance to LTC workers, who are at risk of facing more health issues than other workers. This issue is key to increase the attractiveness of LTC jobs and reduce turnover in the LTC workforce.

- Abstract
Objective: Studies examining what renders workplace interventions to sustain and promote work ability of older workers successful have largely neglected older workers´ perspective. This paper outlines the results of a study with regard to older workers´ experiences and expectations of a workplace intervention. Based on these findings, some reflections on how to improve the design and the implementation of workplace interventions for older workers are provided., Methods: Semi-structured interviews were conducted with older workers (N = 8) participating in a workplace intervention undertaken at one production site of a large manufacturing company in Baden-Wurttemberg/Germany. The interview guide included questions on participants´ experiences with and expectations of the intervention. The interviews were recorded, transcribed verbatim and analyzed using qualitative content analysis according to Mayring (2014)., Results: Older workers´ reported some challenges they face due to their participation in the workplace intervention. These resulted from the work environment (physical challenges), the work process design (new long work cycle), the work organization (tight time allowances, little job rotation, change of teams, age stereotypes) and the management of the workplace intervention (bad information, feeling of occupational insecurity and lack of being valued)., Conclusions: The study shows that challenges arising for older workers from their participation in the workplace intervention may have counteracted the promotion of work ability. As findings suggest, some of these challenges might have been avoided either by considering workers´ perspective during design and implementation of an intervention or by referring to evidence on aging and work ability.

- Abstract
Objective: To determine whether a history of cerebrovascular disease (CVD) increases risk of severe coronavirus disease 2019 (COVID-19)., Methods: In a retrospective multicenter study, we retrieved individual data from in-patients treated March 1 to April 15, 2020 from COVID-19 registries of three hospitals in Saxony, Germany. We also performed a systematic review and meta-analysis following PRISMA recommendations using PubMed, EMBASE, Cochrane Library databases and bibliographies of identified papers (last search on April 11, 2020) and pooled data with those deriving from our multicenter study. Of 3762 records identified, 11 eligible observational studies of laboratory-confirmed COVID-19 patients were included in quantitative data synthesis. Risk ratios (RR) of severe COVID-19 according to history of CVD were pooled using DerSimonian and Laird random effects model. Between-study heterogeneity was assessed using Cochran's Q and I2-statistics. Severity of COVID-19 according to definitions applied in included studies was the main outcome. Sensitivity analyses were conducted for clusters of studies with equal definitions of severity., Results: Pooled analysis included data from 1906 laboratory-confirmed COVID-19 patients (43.9% females, median age ranging from 39 to 76 years). Patients with previous CVD had higher risk of severe COVID-19 than those without [RR 2.07, 95% confidence interval (CI) 1.52-2.81; p < 0.0001]. This association was also observed in clusters of studies that defined severe manifestation of the disease by clinical parameters (RR 1.44, 95% CI 1.22-1.71; p < 0.0001), necessity of intensive care (RR 2.79, 95% CI 1.83-4.24; p < 0.0001) and in-hospital death (RR 2.18, 95% CI 1.75-2.7; p < 0.0001)., Conclusion: A history of CVD might constitute an important risk factor of unfavorable clinical course of COVID-19 suggesting a need of tailored infection prevention and clinical management strategies for this population at risk.

- Abstract
This paper examines the behaviour of mental health care providers in response to marginal payment incentives induced by a discontinuous per diem reimbursement schedule with varying tariff rates over the length of stay. The analyses use administrative data on 12,627 cases treated in 82 psychiatric hospitals and wards in Germany. We investigate whether substantial reductions in marginal reimbursement per inpatient day led to strategic discharge behaviour once a certain length of stay threshold is exceeded. The data do not show gaps and bunches at the duration of treatment when marginal reimbursement decreases. Using logistic regression models, we find that providers did not react to discontinuities in marginal reimbursement by significantly reducing inpatient length of stay around the threshold. These findings are robust in terms of different model specifications and subsamples. The results indicate that if regulators aim to set incentives to decrease LOS, this might not be achieved by cuts in reimbursement over LOS.

- Abstract
Purpose: Preference-based measures are essential for producing quality-adjusted life years (QALYs) that are widely used for economic evaluations. In the absence of such measures, mapping algorithms can be applied to estimate utilities from disease-specific measures. This paper aims to develop mapping algorithms between the MacNew Heart Disease Quality of Life Questionnaire (MacNew) instrument and the English and the US-based EQ-5D-5L value sets., Methods: Individuals with heart disease were recruited from six countries: Australia, Canada, Germany, Norway, UK and the US in 2011/12. Both parametric and non-parametric statistical techniques were applied to estimate mapping algorithms that predict utilities for MacNew scores from EQ-5D-5L value sets. The optimal algorithm for each country-specific value set was primarily selected based on root mean square error (RMSE), mean absolute error (MAE), concordance correlation coefficient (CCC), and r-squared. Leave-one-out cross-validation was conducted to test the generalizability of each model., Results: For both the English and the US value sets, the one-inflated beta regression model consistently performed best in terms of all criteria. Similar results were observed for the cross-validation results. The preferred model explained 59 and 60% for the English and the US value set, respectively. Linear equating provided predicted values that were equivalent to observed values., Conclusions: The preferred mapping function enables to predict utilities for MacNew data from the EQ-5D-5L value sets recently developed in England and the US with better accuracy. This allows studies, which have included the MacNew to be used in cost-utility analyses and thus, the comparison of services with interventions across the health system.

- Abstract
This paper summarises the view of the German Commission on Radiological Protection ("Strahlenschutzkommission", SSK) on the rationale behind the currently valid dose limits and dose constraints for workers recommended by the International Commission on Radiological Protection (ICRP). The paper includes a discussion of the reasoning behind current dose limits followed by a discussion of the detriment used by ICRP as a measure for stochastic health effects. Studies on radiation-induced cancer are reviewed because this endpoint represents the most important contribution to detriment. Recent findings on radiation-induced circulatory disease that are currently not included in detriment calculation are also reviewed. It appeared that for detriment calculations the contribution of circulatory diseases plays only a secondary role, although the uncertainties involved in their risk estimates are considerable. These discussions are complemented by a review of the procedures currently in use in Germany, or in discussion elsewhere, to define limits for genotoxic carcinogens. To put these concepts in perspective, actual occupational radiation exposures are exemplified with data from Germany, for the year 2012, and regulations in Germany are compared to the recommendations issued by ICRP. Conclusions include, among others, considerations on radiation protection concepts currently in use and recommendations of the SSK on the limitation of annual effective dose and effective dose cumulated over a whole working life.

- Abstract
In this paper, I analyze whether premium refunds can reduce ex-post moral hazard behavior in the health insurance market. I do so by estimating the effect of these refunds on different measures of medical demand. I use panel data from German sickness funds that cover the years 2006-2010 and I estimate effects for the year 2010. Applying regression adjusted matching, I find that choosing a tariff that contains a premium refund is associated with a significant reduction in the probability of visiting a general practitioner. Furthermore, the probability of visiting a doctor due to a trivial ailment such as a common cold is reduced. Effects are mainly driven by younger (and, therefore, healthier) individuals, and they are stronger for men than for women. Medical expenditures for doctor visits are also reduced. I conclude that there is evidence that premium refunds are associated with a reduction in ex-post moral hazard. Robustness checks support these findings. Yet, using observable characteristics for matching and regression, it is never possible to completely eliminate a potentially remaining selection bias and results may not be interpreted in a causal manner.

- Abstract
This paper presents a new approach to deal with spatial inequalities in risk adjustment between health insurances. The shortcomings of non-spatial and spatial fixed effects in risk adjustment models are analysed and opposed against spatial kernel estimators. Theoretical and empirical evidence suggests that a reasonable choice of the spatial kernel could limit the spatial uncertainty of the modifiable area unit problem under heavy-tailed claims data, leading to more precise predictions and economically positive incentives on the healthcare market. A case study of the German risk adjustment shows a spatial risk spread of 86 Euro p.c., leading to incentives for spatial risk selection. The proposed estimator eliminates this issue and conserves incentives for services optimisation.

- Abstract
Competition in hospital services has been fostered in an increasing number of OECD countries with the goal that hospitals improve quality and/or efficiency. With the same intention competition has been promoted in Germany when introducing a system of prospective payments based on diagnosis-related groups (DRGs) in 2003. Beyond its intended effects, however, the reform led to a substantial increase in hospital activity, particularly for orthopaedic surgery. To shed more light on these developments, this paper analyses the relationship between the rates of certain orthopaedic surgical procedures and hospital competition across and within each of Germany's 402 districts. We measured competition with the Herfindahl-Hirschman Index (HHI) based on market shares for hip replacements, knee replacements and spine surgeries. Using spatial panel regression, which allows for spatial dependency and unobserved individual heterogeneity, we found that the rate of hip and knee replacements rose as market concentration increased. A potential explanation might be that hospitals specialize in these particular procedures.

- Abstract
In response to the growing burden of obesity, public primary prevention programs against obesity have been widely recommended. Several studies have estimated the cost-effectiveness of diabetes-prevention trials for different countries. Nevertheless, it is still controversial if prevention conducted in more real-world settings and among people with increased risk but not yet exhibiting increased glucose tolerance can be a cost-saving strategy to cope with the obesity epidemic. We examine this question in a simulation model based on the results of the M.O.B.I.L.I.S program, a German lifestyle intervention to reduce obesity, which is directed on the high-risk group of people who are already obese. The contribution of this paper is the use of 4-year follow-up data on the intervention group and a comparison with a control group formed by SOEP respondents as inputs in a Markov model of the long-term cost savings through this intervention due to the prevention of type 2 diabetes. We show that from the point of view of a health insurer, these programs can pay for themselves.

- Abstract
The paper describes the importance of toxicology as a discipline, its past achievements, current scientific challenges, and future development. Toxicological expertise is instrumental in the reduction of human health risks arising from chemicals and drugs. Toxicological assessment is needed to evaluate evidence and arguments, whether or not there is a scientific base for concern. The immense success already achieved by toxicological work is exemplified by reduced pollution of air, soil, water, and safer working places. Predominantly predictive toxicological testing is derived from the findings to assess risks to humans and the environment. Assessment of the adversity of molecular effects (including epigenetic effects), the effects of mixtures, and integration of exposure and biokinetics into in vitro testing are emerging challenges for toxicology. Toxicology is a translational science with its base in fundamental science. Academic institutions play an essential part by providing scientific innovation and education of young scientists.

- Abstract
The objective of this paper is to quantify selection effects related to blood donation behavior and their impact on donors' perceived health status. We rely on data from the 2009 and 2010 survey waves of the German socio-economic panel (N = 12,000), including information on health-related, demographic and psychographic factors as well as monetary donation behavior and volunteer work. We propose a propensity score matching approach to control for the healthy donor effect related to the health requirements for active blood donations. We estimate two separate models and quantify selection biases between (1) active and inactive blood donors and (2) active donors and non-donors. Our results reveal that active donors are more satisfied with their health status; after controlling for selection effects, however, the differences become non-significant, revealing selection biases of up to 82% compared with non-donors. These differences also exist between active and inactive donors, but the differences are less distinct. Our methodological approach reveals and quantifies selection biases attributable to the healthy donor effect. These biases are substantial enough to lead to erroneous statistical artifacts, implying that researchers should rigorously control for selection biases when comparing the health outcomes of different blood donor groups.

- Abstract
It is still an open question whether increasing life expectancy as such causes higher health care expenditures (HCE) in a population. According to the "red herring" hypothesis, the positive correlation between age and HCE is exclusively due to the fact that mortality rises with age and a large share of HCE is caused by proximity to death. As a consequence, rising longevity-through falling mortality rates-may even reduce HCE. However, a weakness of many previous empirical studies is that they use cross-sectional evidence to make inferences on a development over time. In this paper, we analyse the impact of rising longevity on the trend of HCE over time by using data from a pseudo-panel of German sickness fund members over the period 1997-2009. Using (dynamic) panel data models, we find that age, mortality and 5-year survival rates each have a positive impact on per-capita HCE. Our explanation for the last finding is that physicians treat patients more aggressively if the results of these treatments pay off over a longer time span, which we call "Eubie Blake effect". A simulation on the basis of an official population forecast for Germany is used to isolate the effect of demographic ageing on real per-capita HCE over the coming decades. We find that, while falling mortality rates as such lower HCE, this effect is more than compensated by an increase in remaining life expectancy so that the net effect of ageing on HCE over time is clearly positive.

- Abstract
The dynamics of drug launch has been an under-researched area, especially in the context of developing countries, which have diverse disease profiles and weaker forms of regulation compared to developed countries. A limited set of studies, undertaken in recent years, on the diffusion of new drugs in developing countries indeed conjectures the importance of these factors in shaping drug launch dynamics. Taking a survival analysis approach, we investigate the delay of new drug launch in India for drugs launched in the German market during 1990-2004, when, due to weak intellectual property rights (IPR), not only the innovators but also domestic firms could launch new drug molecules in the country. The paper makes an attempt to distinguish between the commercial success of a new drug and its innovativeness. We find little association between these two characteristics of a drug. Also, the influence of global commercial success in shortening delay is much stronger than that of innovativeness. The study also finds interesting results for the threat of imposition of a strong IPR system, market structure and first mover advantages. Policy implications are discussed briefly.

- Abstract
Purpose: Clinical pathways (CP) are nowadays used in numerous institutions, but their real impact is still a matter of debate. The optimal design of a clinical pathway remains unclear and is mainly determined by the expectations of the individual institution. The purpose of the here described pilot project was the development of two CP (colon and rectum carcinoma) according to Business Process Modeling Notation (BPMN) and Tangible Business Process Modeling (t.BPM)., Methods: BPMN is an established standard for business process modelling in industry and economy. It is, in the broadest sense, a computer programme which enables the description and a relatively easy graphical imaging of complex processes. t.BPM is a modular construction system of the BPMN symbols which enables the creation of an outline or raw model, e.g. by placing the symbols on a spread-out paper sheet. The thus created outline can then be transferred to the computer and further modified as required. CP for the treatment of colon and rectal cancer have been developed with support of an external IT coach., Results: The pathway was developed in an interdisciplinary and interprofessional manner (55 man-days over 15 working days). During this time, necessary interviews with medical, nursing and administrative staffs were conducted as well. Both pathways were developed parallel. Subsequent analysis was focussed on feasibility, expenditure, clarity and suitability for daily clinical practice. The familiarization with BPMN was relatively quick and intuitive. The use of t.BPM enabled the pragmatic, effective and results-directed creation of outlines for the CP. The development of both CP was finished from the diagnostic evaluation to the adjuvant/neoadjuvant therapy and rehabilitation phase. The integration of checklists, guidelines and important medical or other documents is easily accomplished. A direct integration into the hospital computer system is currently not possible for technical reasons., Conclusion: BPMN and t.BPM are sufficiently suitable for the planned modelling and imaging of CP. The application in medicine is new, and transfer from the industrial process management is in principle possible. BPMN-CP may be used for teaching and training, patient information and quality management. The graphical image is clearly structured and appealing. Even though the efficiency in the creation of BPMN-CP increases markedly after the training phase, high amounts of manpower and time are required. The most sensible and consequent application of a BPMN-CP would be the direct integration into the hospital computer system. The integration of a modelling language, such as BPMN, into the hospital computer systems could be a very sensible approach for the development of new hospital information systems in the future.

- Abstract
Over the last decades, methods for the economic evaluation of health care technologies were increasingly used to inform reimbursement decisions. For a short time, the German Statutory Health Insurance makes use of these methods to support reimbursement decisions on patented drugs. In this context, the discounting procedure emerges as a critical component of these methods, as discount rates can strongly affect the resulting incremental cost-effectiveness ratios. The aim of this paper is to identify the appropriate value of a social discount rate to be used by the German Statutory Health Insurance for the economic evaluation of health technologies. On theoretical grounds, we build on the widespread view of contemporary economists that the social rate of time preference (SRTP) is the adequate social discount rate. For quantifying the SRTP, we first apply the market behaviour approach, which assumes that the SRTP is reflected in observable market interest rates. As a second approach, we derive the SRTP from optimal growth theory by using the Ramsey equation. A major part of the paper is devoted to specify the parameters of this equation. Depending on various assumptions, our empirical findings result in the range of 1.75-4.2% for the SRTP. A reasonable base case discount rate for Germany, thus, would be about 3%. Furthermore, we deal with the much debated question whether a common discount rate for costs and health benefits or a lower rate for health should be applied in health economic evaluations. In the German social health insurance system, no exogenously fixed budget constraint does exist. When evaluating a new health technology, the health care decision maker is obliged to conduct an economic evaluation in order to examine whether there is an economically appropriate relation between the value of the health gains and the additional costs which are given by the value of the consumption losses due to the additional health care expenditures. Therefore, a discount rate lower than the SRTP for consumption should be applied if an increase in the consumption value of health is expected. However, given the limited empirical evidence on the relationship between consumption and the value of health, it is hardly possible to make reliable forecasts of this value. Regarding the practice of the German evaluation authority, it is not recommended to use differential discounting in the base case. Instead, the issue of differential discounting should be addressed in sensitivity analyses. Reducing the discount rate for health compared to the rate for costs by a figure in the range between near 0% and 3% may be considered to be appropriate for Germany.

- Abstract
This paper shows that patients with private health insurance (PHI) are being offered significantly shorter waiting times than patients with statutory health insurance (SHI) in German acute hospital care. This behavior may be driven by the higher expected profitability of PHI relative to SHI holders. Further, we find that hospitals offering private insurees shorter waiting times when compared with SHI holders have a significantly better financial performance than those abstaining from or with less discrimination.

- Abstract
Purpose: Correct diagnosis, surgical treatment, and perioperative management of patients with esophageal carcinoma remain crucial for prognosis within multimodal treatment procedures. This study aims to achieve a consensus regarding current management strategies in esophageal cancer by questioning a panel of experts from the German Advanced Surgical Treatment Study (GAST) group, comprised of 9 centers specialized in esophageal surgery, with a combined total of >220 esophagectomies per year., Materials and Methods: The Delphi method, a systematic and interactive, evidence-based approach, was used to obtain consensus statements from the GAST group regarding ambiguities and disparities in diagnosis, patient selection, surgical technique, and perioperative management of patients with esophageal carcinoma. After four rounds of surveys, agreement was measured by Likert scales and defined as full (100% agreement), near (≥66.6% agreement), or no consensus (<66.6% agreement)., Results: Full or near consensus was obtained for essential aspects of esophageal cancer staging, proper surgical technique, perioperative management and indication for primary surgery, and neoadjuvant treatment or palliative treatment. No consensus was achieved regarding acceptability of minimally invasive technique and postoperative nutrition after esophagectomy., Conclusion: The GAST consensus statement represents a position paper for treatment of patients with esophageal carcinoma which both contributes to the development of clinical treatment guidelines and outlines topics in need of further clinical studies.

- Abstract
Purpose: This paper seeks to outline the development of disaster medicine services in Germany and the preparedness of the security and rescue forces for mass casualty incidents after an accident, a natural disaster or a terrorist attack., Method: The method used was review of articles and interview with experts., Results: The plane crash at the 1988 Ramstein air show highlighted problems in the approach to incident management. Following this event, Germany improved the medical management of major incidents. At the railway accident in Eschede in 1998, a "proof of concept" was evident. The newest increases of terrorist threats were also turning points in the further development of disaster medicine in Germany., Conclusions: Emergency medical training must be adapted to the increase in disasters, mass casualty incidents, and terrorist threats.

- Abstract
A previous analysis of the radon-related lung cancer mortality risk, in the German uranium miners cohort, using Poisson modeling techniques, noted internal (spontaneous) rates that were higher on average than the external rates by 16.5% (95% CI: 9%; 24%). The main purpose of the present paper is to investigate the nature of, and possible reasons for, this difference by comparing patterns in spontaneous lung cancer mortality rates in a cohort of male miners involved in uranium extraction at the former Wismut mining company in East Germany with national male rates from the former German Democratic Republic. The analysis is based on miner data for 3,001 lung cancer deaths, 1.76 million person-years for the period 1960-2003, and national rates covering the same calendar-year range. Simple "age-period-cohort" graphical analyses were applied to assess the main qualitative differences between the national and cohort baseline lung cancer rates. Some differences were found to occur mainly at higher attained ages above 70 years. Although many occupational risk factors may have contributed to these observed age differences, only the effects of smoking have been assessed here by applying the Peto-Lopez indirect method for calculating smoking attributability. It is inferred that the observed age differences could be due to the greater prevalence of smoking and more mature smoking epidemic in the Wismut cohort compared to the general population of the former German Democratic Republic. In view of these observed differences between external population-based rates and internal (spontaneous) cohort baseline lung cancer rates, it is strongly recommended to apply only the internal rates in future analyses of uranium miner cohorts., (© Springer-Verlag 2010)

- Abstract
Neurosurgeons are mainly concerned with child abuse in cases of severe cranio-cerebral trauma. Aim of the present paper is to highlight the clinical picture and symptoms in cases of child abuse and our multidisciplinary approach to reveal a solid diagnosis. The detection of child abuse requires a high index of suspicion, especially in cases of subtle injuries. Besides reporting to the appropriate agencies primary goals are to terminate suspected abuse and to prevent further harm to the child. All this requires a confirmed diagnosis.

This is a comment on a recent paper by Bengt Liljas (Eur J Health Econ 11:5-13, 2010) in this Journal. The author's analysis is flawed because he fails to take the envelope theorem into account. As a bottom line, we conclude that from a welfare theoretic point of view, future consumption and future labor hours should not be considered in a valid CEA.

- Abstract
This paper analyses the effect of the onset of disability on the well-being of individuals. In particular, we are interested in studying whether people can adapt to disability over time after its onset. Using longitudinal data from the German Socio-Economic Panel (GSOEP) for the period 1984-2006, we estimate life satisfaction equations using a fixed-effects model for working-age males (aged 21-58). The results show that disability has a significant negative effect on life satisfaction, but, in time, hedonic adaptation will return disabled males to life satisfaction levels registered by those who have not become disabled. These findings contribute to supporting the idea within psychology literature that individuals bounce back from painful events or adversities (such as the onset of disability) to achieve initial life satisfaction scores.

- Abstract
The potential of secondary prevention measures, such as cancer screening, to produce cost savings in the healthcare sector is a controversial issue in healthcare economics. Potential savings are calculated by comparing treatment costs with the cost of a prevention program. When survivors' subsequent unrelated health care costs are included in the calculation, however, the overall cost of disease prevention rises. What have not been studied to date are the secondary effects of fatal disease prevention measures on social security systems. From the perspective of a policy maker responsible for a social security system budget, it is not only future healthcare costs that are relevant for budgeting, but also changes in the contributions to, and expenditures from, statutory pension insurance and health insurance systems. An examination of the effect of longer life expectancies on these insurance systems can be justified by the fact that European social security systems are regulated by the state, and there is no clear separation between the financing of individual insurance systems due to cross-subsidisation. This paper looks at how the results of cost-comparison analyses vary depending on the inclusion or exclusion of future healthcare and non-healthcare costs, using the example of colorectal cancer screening in the German general population. In contrast to previous studies, not only are future unrelated medical costs considered, but also the effects on the social security system. If a German colorectal cancer screening program were implemented, and unrelated future medical care were excluded from the cost-benefit analysis, savings of up to 548 million euros per year would be expected. The screening program would, at the same time, generate costs in the healthcare sector as well as in the social security system of 2,037 million euros per year. Because the amount of future contributions and expenditures in the social security system depends on the age and gender of the recipients of the screening program (i.e. survivors of a typically fatal condition), the impact of age and gender on the results of a cost-comparison analysis of colorectal cancer screening are presented and discussed. Our study shows that colorectal cancer screening generates individual cost savings in the social security system up to a life expectancy of 60 years. Beyond that age, the balance between a recipient's social security contributions and insurance system expenditure is negative. The paper clarifies the relevance of healthcare costs not related to the prevented disease to the economic evaluation of prevention programs, particularly in the case of fatal diseases such as colorectal cancer. The results of the study imply that, from an economic perspective, the participation of at-risk individuals in disease prevention programs should be promoted.

- Abstract
Introduction: At the end of the nineteenth century, three prominent German surgical journals (i.e., "Deutsche Zeitschrift für Chirurgie," "Bruns' Beiträge," and "Langenbeck's Archiv für Klinische Chirurgie") dominated the surgical academic scene in Germany. While written exclusively in German, these publications were widely read in Germany as well as abroad. Today, only the oldest of these journals, Langenbeck's Archiv, remains. In 1913, the "Zentralorgan für die gesamte Chirurgie" was instituted in Germany as a separate publication specifically dedicated to improve the communication of foreign scientific contributions. However, on a number of occasions, landmark papers from outside the country were not fully appreciated by the German readership, just as nowadays, key surgical papers published in German are only infrequently acknowledged in the Anglo-American scientific literature. At all times, innovative scientific works had a difficult time finding open ears and minds if they challenged long-held academic preconceptions. It appeared hard to question dogmas that readers had believed to be true for so long. After 1945, German surgery found itself eclipsed in many areas by new developments in the anglophone surgical communities since the academic exchange of ideas had been largely curtailed for more than a decade. English-speaking surgeons were more numerous, and the flow of communication became easier and more and more rapid., Conclusion: Over time, the entire field of surgery in Germany began to emulate what had proven so effective in the English-speaking world. Langenbeck's Archiv is now published in English.

- Abstract
Purpose: The aim of this paper was to analyse the cross-sectional associations between work-related stressors and work ability and to investigate moderator-type effects of internal health-related control beliefs (IHRCB)., Methods: A total of 1,348 working men and women aged 30-59 years from the baseline survey of the German Sociomedical Panel of Employees were included in the analyses. Work ability was assessed by the Work Ability Index (WAI). Work-related stressors were defined as physical demands and in terms of the demand-control model and the effort-reward imbalance model., Results: Restrictions of work ability were explained independently by physical demands and by work stress exposure due to high demand and low control and due to effort-reward imbalance. These effects were more serious for workers with low IHRCB than those with high IHRCB., Conclusions: IHRCB are an important personal resource that might moderate the effect of work-related stressors on work ability. However, longitudinal analyses are required to confirm these results.

- Abstract
Objective: The exposure situation of German hard coal miners with respect to the components nitrogen monoxide and nitrogen dioxide. Carbon monoxide was measured additionally and the results are displayed but not discussed in detail in this paper. The data were used to estimate personal long-term exposures in an inception cohort., Methods: For all three components, time weighted 8-h shift values were determined for typical groups of coalminers according to the European measurement standard. An expert panel from the coal mining company made an effort to estimate major potential changes in the exposure situation., Results: The main sources of nitrogen oxides and carbon monoxide in hard coal mining were the diesel engines. Blasting fumes contributed only to a lesser degree and with different exposure characteristics, e.g. much reduced NO(2) levels compared to the mines' rear areas. As rough 8 h-shift averages describing the current exposure situation, we found 1.35 ppm NO and 0.21 ppm NO(2) for the diesel engine drivers. Blasting specialists were more difficult to evaluate but rough 8 h-shift averages of 0.84 ppm NO and 0.014 ppm NO(2) could be estimated from our measurement series. By applying these data and the estimates of experts about the retrospective exposure situation to a cohort of 1,369 coalminers, we derived mean (max) cumulative exposures in ppm x number of shifts of 1,748 (5,928) for NO and 19.6 (1,013) for NO(2) when summarizing over the follow-up period from 1974 until 1998., Conclusions: Especially for the diesel engine drivers, exposure can be regarded as rather high, in particular, when compared to recommended limits by SCOEL and MAK, though the exposures have been in line with the enforced German occupational exposure limits. Whether this exposure situation has caused adverse health effects will be investigated epidemiologically.

- Abstract
To eradicate rabies in foxes, almost 97 million oral rabies vaccine baits have been distributed in Germany and Austria since 1983 and 1986, respectively. Since 2007, no terrestrial cases have been reported in either country. The most widely used oral rabies vaccine viruses in these countries were SAD (Street Alabama Dufferin) strains, e.g. SAD B19 (53.2%) and SAD P5/88 (44.5%). In this paper, we describe six possible vaccine-virus-associated rabies cases in red foxes (Vulpes vulpes) detected during post-vaccination surveillance from 2001 to 2006, involving two different vaccines and different batches. Compared to prototypic vaccine strains, full-genome sequencing revealed between 1 and 5 single nucleotide alterations in the L gene in 5 of 6 SAD isolates, resulting in up to two amino acid substitutions. However, experimental infection of juvenile foxes showed that those mutations had no influence on pathogenicity. The cases described here, coming from geographically widely separated regions, do not represent a spatial cluster. More importantly, enhanced surveillance showed that the vaccine viruses involved did not become established in the red fox population. It seems that the number of reported vaccine virus-associated rabies cases is determined predominantly by the intensity of surveillance after the oral rabies vaccination campaign and not by the selection of strains.
