Having teaching staff with didactic qualifications in university teaching leads to a measurable improvement in academic skills among students. Previous recommendations on the type and scope of medical didactic qualification measures primarily apply to teaching staff at university and in-patient settings. The situation of primary care medicine, which often employs external lecturers and whose teaching takes place to a considerable extent in decentralized training facilities (teaching practices) is not adequately addressed. Taking into account a survey on the status quo at higher education institutions for General Practice in Germany, recommendations for minimum standards are made, based on national and international recommendations on the content and scope of medical didactic qualification measures. These recommendations include preliminary work by the Personnel and Organizational Development in Teaching (POiL) Committee of the Society for Medical Education (GMA), the MedicalTeachingNetwork (MDN), the Society of University Teaching Staff in General Medicine (GHA) as well as the experiences of the committee members, who hail from the field of general medicine, internal medicine and pediatrics amongst others., Competing Interests: The authors declare that they have no competing interests., (Copyright © 2020 Böhme et al.)

Introduction: A "smoke-free" society is assumed if less than 5 % of a population smoke. We predict when this goal could be reached in Germany. To reduce the proportion of smokers in the population, the World Health Organization recommends a bundle of measures (MPOWER) that should minimize both the supply of and the demand for tobacco. The current level of implementation of these recommendations in Germany is presented., Methods: A total of 21 representative cross-sectional surveys of the Drug Affinity Study and the Epidemiological Survey of Substance Abuse since 2000/2001 with adolescents and adults show the smoking behavior of the population until 2018. Per capita consumption of factory-built and self-made cigarettes during the same period is used as an objective data basis. Regression analyses are used to model the date at which less than 5 % of the German population smoke. A selective literature review is carried out to describe the implementation of the MPOWER program., Results: Before 2000 there was no trend in Germany towards non-smoking. After the implementation of various preventive measures such as price increases for tobacco products and the introduction of non-smoking protection laws, the spread of smoking among the population has steadily decreased since 2000. By 2018, the 5 % prevalence target among adolescents had almost been reached, as the relative proportion of adolescents who smoked fell by 20.9 percentage points to 6.6 %. The relative proportion of smoking in adult women fell by 12.1 percentage points to 18.5 %, the relative proportion of smoking in men by 14.8 percentage points to 24.2 %. Assuming a linear trend, the prevalence target of less than 5 % smoking adults can be reached by around 2043. Of the six recommended measures of the MPOWER program, Germany is currently only implementing the monitoring of tobacco consumption in society without compromises., Discussion: After various tobacco prevention measures were implemented, a trend towards non-smoking began in Germany. The continual price increase recommended by the World Health Organization, the further restriction of availability, the ban on all tobacco advertising and promotion, the support of smoking cessation as well as the education of the population appear to be necessary to reinforce this trend and to achieve the health policy goal of a smoke-free society in 2040., Competing Interests: RH, BI und MM beteiligen sich an der Implementation des gemeinnützigen, schulbasierten Präventionsprogramms „Be Smart – Don’t Start“.

Digitalization in the healthcare system is a great challenge for rheumatology as for other medical disciplines. The German Society for Rheumatology (DGRh) wants to actively participate in this process and benefit from it. By founding the commission on digital rheumatology, the DGRh has created a committee that deals with the associated tasks, advises the DGRh on questions and positions associated with digital health. For the DGRh, this affects the most diverse areas of digitalization in medicine and rheumatology. This position paper presents the topics and developments currently handled by the commission and the tasks identified.

Media-associated disorders in childhood and adolescence: Evidence paper of the joint addiction commision of the German societies and professional associations of child and adolescent psychiatry and psychotherapy Abstract. Media-associated disorders (MAD) describe the problematic use of the internet, certain electronic devices in general as well as digital applications. During childhood and adolescence, digital games and social media are the most commonly used applications. In May 2019, as first MAD "gaming disorder" was included as a clinical diagnosis in the ICD-11. The prevalence of MAD in German children and adolescents is estimated to lie between 3 % and 5 %. In most cases, MAD are accompanied by psychiatric comorbidities. MAD ensue because of dysfunctional learning processes in combination with general and specific risk factors. They are associated with neural changes like those of substance-associated addictions. Diagnostics can be based on validated questionnaires and clinical exploration, though a standardized diagnostic path is not yet common. Treatment depends on the level of severity and generally comprises outpatient, day-clinic, and inpatient therapy approaches with elements from cognitive-behavioral therapy and under parental involvement. Suitable treatments are not yet available in all German regions and have also not been sufficiently evaluated. Moreover, only a few studies exist on the efficacy of prevention measures addressing MAD in children and adolescents. Thus, further research is strongly required.

Increased awareness of the rising antimicrobial resistance problem and impending loss of suitable treatment options for infectious diseases have changed patient care. Antimicrobial/antibiotic stewardship (ABS) activities aiming to optimize antimicrobial treatment were specified in international (WHO, ECDC) and national programmes and evidence-based practice guidelines. In Germany, ABS in hospitals is enshrined in the Infection Protection Act §23 and in a national guideline. The position paper presents the goals and tasks of ABS as well as the necessary organisational and staff requirements.Qualified training and education, mandates and support from hospital directors, and the provision of sufficient resources are essential prerequisites for the successful work of the ABS team. The ABS team should work hospital-wide across clinical services. Their main tasks are developing and implementing an ABS programme tailored to local needs and the conditions of the hospital, taking into account anti-infective drug prescribing, the resistance situation and case mix. Their tasks also include drafting and implementing in-house recommendations for diagnosis, prophylaxis and treatment of important infectious diseases. The ABS team should be interdisciplinary and include specially qualified doctors and pharmacists. Doctors commissioned for ABS should support this team and take the department-specific concerns into account. The document specifies a minimum ABS staff of one full-time equivalent (FTE) per 500 beds. Depending on the case mix and specialties, additional staff may be required. It proposes that there should be 0.1 FTE doctors commissioned for ABS per 100 beds.

Tick-borne diseases are a public health issue. To predict vector tick abundance and activity, it is necessary to understand the driving factors for these variables. In this study, the activity of Ixodes ricinus was investigated in forest and meadow habitats in Germany with a focus on abiotic factors. Ixodes ricinus adults, nymphs and larvae were caught by flagging over a period of 2 years. Microclimatic and weather conditions were recorded at the collection sites. Statistical models were applied to describe correlations between abiotic factors and tick activity in univariable and multivariable analyses. Tick activity was observed in a broad range of air temperature between 3 and 28 °C, and air humidity varied between 35 and 95%. In general, tick activity of nymphs and larvae was higher in forest habitats than that in meadows. With the exception of a single specimen of Dermacentor reticulatus, all ticks were Ixodes ricinus, most of them nymphs (63.2% in 2009 and 75.2% in 2010). For the latter, a negative binomial mixed-effects model fitted best to the observed parameters. The modelling results showed an activity optimum between 20 and 23 °C for air temperature and between 13 and 15 °C for ground temperature. In univariable analyses, the collection site, month, season, ground and air temperature were significant factors for the number of ticks caught and for all life stages. In the multivariable analysis, temperature, season and habitat turned out to be key drivers. Ixodes ricinus positive for RNA of tick-borne encephalitis virus was only found at a single sampling site. The results of this study can be used in risk assessments and to parameterise predictive models.

Purpose: Current trials on adjunctive treatment with antiseizure drugs often do not reveal results which are relevant for clinical practice., Method: Therefore, an interdisciplinary group of German experts discussed a new framework for future antiseizure drug (ASD) trials in adults. This group included members of the executive board of the German Society of Epileptology, of the German institutes for health technology assessment (HTA), of patient organizations and of drug manufacturers. Agreement was reached by consensus decision making after intensive discussion of the findings of a narrative review of the current literature., Results: The group jointly recommends that ASD trials in adults should be based on and include relevant patient groups, e.g. elderly patients and patients with relevant co-morbidities, should adopt a study duration of at least 12 months, should avoid placebo arms, should include active comparators of clinical relevance, may be designed as open label trials with blinded outcome measurements, should focus on patient relevant outcomes that reflect the impact of benefits and harms of treatments on daily living, such as seizure freedom and seizure severity as well as retention rate, functional outcomes and quality of life as compound measures, and should avoid arbitrary and non-sensitive primary endpoints such as dichotomized changes in seizure frequency., Conclusions: This paper focused on improved head-to-head trials on adjunctive treatment with antiseizure drugs. The group welcomes any further work and discussion to enhance future studies which can be applied to the entire spectrum of potentially meaningful study populations and outcomes., (Copyright © 2020 British Epilepsy Association.

Background: The Schedule for the Evaluation of Individual Quality of Life-Direct Weighting (SEIQoL-DW) is a prevalent face-to-face interview method for measuring quality of life by integrating respondent-generated dimensions. To apply this method in clinical trials, a paper-administered alternative would be of interest. Therefore, our study aimed to analyze the agreement between the SEIQoL-DW and a paper questionnaire version (SEIQoL-PF/G)., Methods: In a crossover design, both measures were completed in a random sequence. 104 patients at a heart surgery hospital in Germany were randomly assigned to receive either the SEIQoL-DW or the SEIQoL-PF/G as the first measurement in the sequence. Patients were approached on their earliest stable day after surgery. The average time between both measurements was 1 day (mean 1.3; SD 0.8). Agreement regarding the indices, ratings, and weightings of nominated life areas (cues) was explored using Bland-Altman plots with 95% limits of agreement (LoA). Agreement of the SEIQoL indices was defined as acceptable if the LoA did not exceed a threshold of 10 scale points. Data from n = 99 patients were included in the agreement analysis., Results: Both measures led to similarly nominated cues. The most frequently nominated cues were "physical health" and "family". In the Bland-Altman plot, the indices showed a mean of differences of 2 points (95% CI, - 1 to 6). The upper LoA showed a difference of 36 points (95% CI, 30 to 42), and the lower LoA showed a difference of - 31 points (95% CI, - 37 to - 26). Thus, the LoAs and confidence intervals exceeded the predefined threshold. The Bland-Altman plots for the cue levels and cue weights showed similar results. The SEIQoL-PF/G version showed a tendency for equal weighting of cues, while the weighting procedure of the SEIQoL-DW led to greater variability., Conclusions: For cardiac surgery patients, use of the current version of the SEIQoL-PF/G as a substitute for the SEIQoL-DW is not recommended. The current questionnaire weighting method seems to be unable to distinguish weighting for different cues. Therefore, the further design of a weighting method without interviewer support as a paper-administered measure of individual quality of life is desirable.

In Germany, there are currently many voices calling for a reform of hospital planning and reimbursement to correct some aberrations of the last decades and to enable the system to cope with future challenges. Some recent political decisions to change the structures of emergency medical services as well as the introduction of mandatory nurse-to-patient ratios and the exclusion of the cost for nursing from the case-based hospital reimbursement represent first steps of a reform, which also affects intensive care and emergency medicine. In this discussion paper a group of intensivists, emergency physicians, medical controllers, and representatives of nurses suggest more far-reaching changes, which can be summarized in 5 points: (1) General hospitals with intensive care units (ICU) and emergency departments (ED) which are part of the emergency medical system should be considered as an element of public service and be planned accordingly. (2) The planning of the intensive care infrastructure should be based on the three levels of emergency medical services to identify hospitals that are system relevant and to define appropriate criteria for structure and quality measures. (3) Hospital reimbursement should consist of a base amount (covering costs for hospital staff, infrastructure plus investments) and case-based fees (covering material costs). (4) To determine the requirements for nurses, physicians, and other medical staff, adequate tools for ICU and ED should be applied. (5) For these purposes as well as for quality management and optimal medical care, hospitals should be provided with a substantially improved IT-infrastructure.

Background: 5-Fluorouracil (FU) is one of the most commonly used cytostatic drugs in the systemic treatment of cancer. Treatment with FU may cause severe or life-threatening side effects and the treatment-related mortality rate is 0.2-1.0%., Summary: Among other risk factors associated with increased toxicity, a genetic deficiency in dihydropyrimidine dehydrogenase (DPD), an enzyme responsible for the metabolism of FU, is well known. This is due to variants in the DPD gene (DPYD). Up to 9% of European patients carry a DPD gene variant that decreases enzyme activity, and DPD is completely lacking in approximately 0.5% of patients. Here we describe the clinical and genetic background and summarize recommendations for the genetic testing and tailoring of treatment with 5-FU derivatives. The statement was developed as a consensus statement organized by the German Society for Hematology and Medical Oncology in cooperation with 13 medical associations from Austria, Germany, and Switzerland. Key Messages: (i) Patients should be tested for the 4 most common genetic DPYD variants before treatment with drugs containing FU. (ii) Testing forms the basis for a differentiated, risk-adapted algorithm with recommendations for treatment with FU-containing drugs. (iii) Testing may optionally be supplemented by therapeutic drug monitoring., (© 2020 S. Karger AG, Basel.)

Against the background of the pandemic caused by infection with the SARS-CoV-2 virus, the German Respiratory Society has appointed experts to develop therapy strategies for COVID-19 patients with acute respiratory failure (ARF). Here we present key position statements including observations about the pathophysiology of (ARF). In terms of the pathophysiology of pulmonary infection with SARS-CoV-2, COVID-19 can be divided into 3 phases. Pulmonary damage in advanced COVID-19 often differs from the known changes in acute respiratory distress syndrome (ARDS). Two types (type L and type H) are differentiated, corresponding to early- and late-stage lung damage. This differentiation should be taken into consideration in the respiratory support of ARF. The assessment of the extent of ARF should be based on arterial or capillary blood gas analysis under room air conditions, and it needs to include the calculation of oxygen supply (measured from the variables of oxygen saturation, hemoglobin level, the corrected values of Hüfner's factor, and cardiac output). Aerosols can cause transmission of infectious, virus-laden particles. Open systems or vented systems can increase the release of respirable particles. Procedures in which the invasive ventilation system must be opened and endotracheal intubation carried out are associated with an increased risk of infection. Personal protective equipment (PPE) should have top priority because fear of contagion should not be a primary reason for intubation. Based on the current knowledge, inhalation therapy, nasal high-flow therapy (NHF), continuous positive airway pressure (CPAP), or noninvasive ventilation (NIV) can be performed without an increased risk of infection to staff if PPE is provided. A significant proportion of patients with ARF present with relevant hypoxemia, which often cannot be fully corrected, even with a high inspired oxygen fraction (FiO2) under NHF. In this situation, the oxygen therapy can be escalated to CPAP or NIV when the criteria for endotracheal intubation are not met. In ARF, NIV should be carried out in an intensive care unit or a comparable setting by experienced staff. Under CPAP/NIV, a patient can deteriorate rapidly. For this reason, continuous monitoring and readiness for intubation are to be ensured at all times. If the ARF progresses under CPAP/NIV, intubation should be implemented without delay in patients who do not have a "do not intubate" order., (© 2020 S. Karger AG, Basel.)

Sarcoidosis is a multisystemic granulomatous disorder which affects the respiratory system in the majority of the cases. Symptomatic cardiac manifestations are found in less than 10 % of the affected cohorts and show a large heterogeneity based on the ethnic background. Cardiac sarcoidosis is not only found in patients with rhythmogenic heart disease, such as atrial and ventricular fibrillation but also in all phenotypes of cardiomyopathy. The overall morbidity and mortality caused by cardiac sarcoidosis in Germany remains unclear and large prospective international observational studies.underline the importance of this disease entity. This consensus paper on diagnostic and therapeutic algorithms for cardiac sarcoidosis is based on a current literature search and forms an expert opinion statement under the auspices of the German Respiratory Society and the German Cardiac Society. The rationale of this statement is to provide algorithms to facilitate clinical decision-making based on the individual case situation., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (© Georg Thieme Verlag KG Stuttgart · New York.)

The "Masterplan Medizinstudium 2020" from the German Federal Government should not be underestimated as only one among many announcement. Thus, the Surgical Working Group on Medical Education (CAL) of the German Association of Surgeons (DGCH) comments on the intended measures of the "Masterplan Medizinstudium 2020" and discusses the challenges, consequences and duties arising from the "Masterplan Medizinstudium 2020" for the representatives of the surgical societies and those engaged in surgical undergraduate training., Competing Interests: Die Autoren geben an, dass kein Interessenkonflikt besteht., (Georg Thieme Verlag KG Stuttgart · New York.)

The article discusses the Best Paper Prize awarded by the journal Computational Optimization and Applications. The winning paper, written by Alberto De Marchi, focuses on a numerical method for convex quadratic programs (QPs), which are optimization problems with quadratic objective functions and polyhedral constraints. De Marchi's method, called QPDO, combines the proximal point algorithm and a globalized Newton-type method to solve QPs efficiently and robustly. The paper's findings have influenced the development of methods for more general problem classes and have potential applications in various fields, including control systems and data science. Alberto De Marchi is a postdoctoral researcher at the University of the Bundeswehr Munich, Germany, with expertise in computational optimization. [Extracted from the article]

Background and Rationale: Xerosis cutis (also referred to as xeroderma, dry skin, asteatosis) affects more than 10 million individuals in Germany. It is among the most common dermatological diagnoses and a cardinal symptom of many dermatological, internal and neurological diseases. Even though it has been established that basic skin care plays a significant role in the management of patients with xerosis cutis, there are as yet no evidence-based algorithms for diagnosis and treatment., Objective: The present position paper provides physicians across all specialties with a practical, symptom-based approach to the prevention, diagnosis and treatment of xerosis cutis., Methods: Within a structured decision-making process, a panel of experienced dermatologists first defined questions relevant to everyday clinical practice, which were then addressed by a systematic review of the literature. Based on the evidence available as well as expert consensus, diagnostic and treatment algorithms were subsequently developed and agreed upon., Results: Xerosis cutis is generally diagnosed on clinical grounds. Possible trigger factors must be avoided, and comorbidities should be adequately and specifically treated. Suitable skin care products should be chosen with a view to improving skin hydration and restoring its barrier function. They should therefore contain both rehydrating and lipid-replenishing components. The "drier" the skin appears, the greater the lipid content should be (preferably using water-in-oil formulations). The choice of ingredients is based on a patient's individual symptoms, such as scaling (e.g., urea), fissures/rhagades (e.g., urea or dexpanthenol), erythema (e.g., licochalcone A) and pruritus (e.g., polidocanol). Other factors to be considered include the site affected and patient age. Ingredients or rather combinations thereof for which there is good clinical evidence should be preferentially used. The best evidence by far is available for urea, whose efficacy in the treatment of xerosis is further enhanced by combining it with other natural moisturizing components and ceramides. The "xerosimeter" is a tool developed in an effort to facilitate patient management and for training purposes. It not only includes practical tools for diagnosis and follow-up but also a classification of ingredients and a structured treatment algorithm., Conclusion: The structured symptom- and evidence-based approach proposed herein contains a road map for diagnosis and treatment of xerosis cutis. It aims to raise awareness in terms of prevention and early treatment of this condition and may thus improve quality of life and prevent potential sequelae., (© 2019 The Authors Journal der Deutschen Dermatologischen Gesellschaft published by John Wiley & Sons Ltd on behalf of Deutsche Dermatologische Gesellschaf.)

Background: The Syria crisis has forced more than 4 million people to leave their homeland. As a result, in 2016, an overwhelming number of refugees reached Germany. In response to this, it was of utmost importance to set up refugee camps and to provide humanitarian aid, but a health surveillance system was also implemented in order to obtain rapid information about emerging diseases., Objective: The present study describes the effects of using digital paper and pen (DPP) technology on the speed, sequence, and behavior of epidemiological documentation in a refugee camp., Methods: DPP technology was used to examine documentation speed, sequence, and behavior. The data log of the digital pens used to fill in the documentation was analyzed, and each pen stroke in a field was recorded using a timestamp. Documentation time was the difference between first and last stroke on the paper, which includes clinical examination and translation., Results: For three months, 495 data sets were recorded. After corrections had been made, 421 data sets were considered valid and subjected to further analysis. The median documentation time was 41:41 min (interquartile range 29:54 min; mean 45:02 min; SD 22:28 min). The documentation of vital signs ended up having the strongest effect on the overall time of documentation. Furthermore, filling in the free-text field clinical findings or therapy or measures required the most time (mean 16:49 min; SD 20:32 min). Analysis of the documentation sequence revealed that the final step of coding the diagnosis was a time-consuming step that took place once the form had been completed., Conclusions: We concluded that medical documentation using DPP technology leads to both an increase in documentation speed and data quality through the compliance of the data recorders who regard the tool to be convenient in everyday routine. Further analysis of more data sets will allow optimization of the documentation form used. Thus, DPP technology is an effective tool for the medical documentation process in refugee camps., (©Kai Kehe, Roland Girgensohn, Walter Swoboda, Dan Bieler, Axel Franke, Matthias Helm, Martin Kulla, Kerstin Luepke, Thomas Morwinsky, Markus Blätzinger, Katalyn Rossmann.

Introduction: The term variations of sex development subsumes a large number of congenital conditions including chromosomal mosaics and variations of chromosomal, gonadal, and phenotypic sex. A situation of this nature may cause severe distress to both, parents and affected persons. One of the reasons for this is the binary form of gender classification in the society. In the past, because of a fear of possible stigmatization and an inability to cope with complex situations, it has been medical policy and practice for newborns to undergo early, mostly 'feminizing' elective surgery with the aim of achieving an outer genital appearance that is unambiguously male or female. Protests by advocacy groups for the most part as well as the results of outcome studies have shown that the development of affected persons may be very different to what has been expected and often does not result in the intended clear female or male gender identity as had been intended. It, therefore, seemed a matter of urgency to implement this new awareness as well as the ethical and personal human rights perspectives in the recommendations for the medical and psychosocial management of diverse sex development (DSD) in the future., Study Design: In 2012, an interdisciplinary group of German academics engaged in the field of DSD decided to work on a consensus paper for this topic. It involved the participation of all faculties and non-scientific groups dealing with DSD, in particular advocacy and service-user groups. In a structured consensus, process recommendations were developed based on scientific literature as well as personal experiences of clinicians and affected individuals., Results: Finally, 37 recommendations were agreed on. The strength of consensus is reflected in the degree of agreement as expressed in percentages., Conclusion: The introduction of the consensus paper reflects on the emerging paradigm shift and the necessity for a more open view of gender within society. The paper is intended to aid the performance of appropriate diagnostics in DSD-affected newborns and especially to help parents and affected persons cope with the biological and social consequences of DSD. With regard to medical or surgical therapy, it gives information about the most recent treatment trends., (Copyright © 2018 Journal of Pediatric Urology Company. Published by Elsevier Ltd.

Background: Currently, more than 30,200,000 COVID-19 cases have been diagnosed in Germany alone. However, data regarding prevalence of COVID-19 in children, both in Germany and internationally, are sparse. We sought to evaluate the number of infected children by measuring IgG antibodies. Methods: Oropharyngeal swabs were collected between December 2020 and August 2021 to measure SARS-CoV-2, and capillary blood for the detection of SARS-CoV-2 antibodies (by rapid test NADAL® and filter paper test Euroimmun® ELISA); venous blood was taken for validation (Roche® ECLIA and recomLine Blot) in 365 German children aged 3–16 years from 30 schools and preschools. We used multiple serological tests because the filter paper test Euroimmun® ELISA performs better in terms of sensitivity and specificity than the rapid test NADAL®. The Roche® ECLIA test is used to detect SARS-CoV-2 spike protein, and the recomLine Blot test is used to rule out the possibility of infection by seasonal SARS-viruses and to test for specific SARS-CoV-2 proteins (NP, RBD and S1). In addition, one parent each (n = 336), and 4–5 teachers/caregivers (n = 90) per institution were tested for IgG antibodies from capillary blood samples. The total study duration was 4 months per child, including the first follow-up after 2 months and the second after 4 months. Results: Of 364 children tested at baseline, 3.6% (n = 13) were positive for SARS-CoV-2 IgG antibodies using Euroimmun® ELISA. Seven children reported previously testing positive for SARS-CoV-2; each of these was confirmed by the Roche® Anti-SARS-CoV-2-ECLIA (antibody to spike protein 1) test. SARS-CoV-2 IgG antibodies persisted over a 4-month period, but levels decreased significantly (p = 0.004) within this timeframe. The median IgG values were 192.0 BAU/ml [127.2; 288.2], 123.6 BAU/ml [76.6; 187.7] and 89.9 BAU/ml [57.4; 144.2] at baseline, 2 months and 4 months after baseline, respectively. During the study period, no child tested positive for SARS-CoV-2 by oropharyngeal swab. A total of 4.3% of all parents and 3.7% of teachers/caregivers tested positive for IgG antibodies by Euroimmun® ELISA at baseline. Conclusion: We noted a rather low seroprevalence in children despite an under-reporting of SARS-CoV-2 infections. Measurement of IgG antibodies derived from capillary blood appears to be a valid tool to detect asymptomatic infections in children. However, no asymptomatic active infection was detected during the study period of 4 months in the whole cohort. Further data on SARS-CoV-2 infections in children are needed, especially in the group of <5-year-olds, as there is currently no licensed vaccine for this age group in Germany. The Robert Koch Institute's Standing Commission on Vaccination (STIKO) recommended COVID-19 vaccination for 12–17 and 5–11 year olds in August 2021 and May 2022 respectively. [ABSTRACT FROM AUTHOR]

The Thirteenth Meeting of the International Congress on Mathematical Education (ICME-13) convened in Hamburg, Germany, in July, 2016. There were two Topic Study Groups (TSGs) dedicated exclusively to adult learners and the authors of this paper served on the organizing committees of these groups. Arrangements were made by the congress committee for the publication of peer-reviewed papers from each TSG by Springer International Publishing AG in a series of edited books. In this paper we focus on our experiences as editors of the monographs resulting from our two TSGs.

Objective: To investigate if paper-based documentation in the authors' emergency medical service (EMS) satisfies scientific requirements., Methods: From 1 July 2007 to 28 February 2008, data from all paper-based protocols of a physician-run EMS in Aachen, Germany, were transferred to a SQL database (n=4815). Database queries were conducted after personal data had been anonymised. Documentation ratios of 11 individual parameters were analysed at two points in time (T1, scene; T2, arrival in emergency department). The calculability of the Mainz Emergency Evaluation Score (MEES, embracing seven vital parameters) was investigated. The calculability of the Revised Trauma Score (RTS) was also determined for all trauma patients (n=408). Fisher's exact test was used to compare differences in ratios at T1 versus T2., Results: The documentation ratios of vital parameters ranged from 99.33% (Glasgow Coma Scale, T1) to 40.31% (respiratory rate, T2). The calculability of the MEES was poor (all missions: 28.31%, T1; 22.40%, T2; p<0.001). In missions that required cardiopulmonary resuscitation (n=87), the MEES was calculable in 9.20% of patients at T1 and 29.89% at T2 (p<0.001). In trauma missions, the RTS was calculable in 37.26% at T1 and 27.70% at T2 (p=0.004)., Conclusions: Documentation of vital parameters is carried out incompletely, and documentation of respiratory rate is particularly poor, making calculation of accepted emergency scores infeasible for a significant fraction of a given test population. The suitability of paper-based documentation is therefore limited. Electronic documentation that includes real-time plausibility checks might improve data quality. Further research is warranted.

This article presents a possible framework for the cooperation of mathematics and physics education research domains. Moreover, the potential topics for such a scientific collaboration are explained by means of a structuring qualitative content analysis of current handbooks and conference proceedings in Germany and Vietnam. These topics can form a basis for further projects on the connection of subject-related didactics. One of these projects is an interdisciplinary course in teacher training at the Hanoi National University of Education (HNUE) as part of the Inter TeTra project between the HNUE and the University of Siegen.

Four experiments were conducted to test whether recent developments in display technology would suffice to eliminate the well-known disadvantages in reading from screen as compared with paper. Proofreading speed and performance were equal for a TFT-LCD and a paper display, but there were more symptoms of eyestrain in the screen condition accompanied by a strong preference for paper (Experiment 1). These results were replicated using a longer reading duration (Experiment 2). Additional experiments were conducted to test hypotheses about the reasons for the higher amount of eyestrain associated with reading from screen. Reduced screen luminance did not change the pattern of results (Experiment 3), but positioning both displays in equal inclination angles eliminated the differences in eyestrain symptoms and increased proofreading speed in the screen condition (Experiment 4). A paper-like positioning of TFT-LCDs seems to enable unimpaired reading without evidence of increased physical strain. Practitioner Summary: Given the developments in screen technology, a re-assessment of the differences in proofreading speed and performance, well-being, and preference between computer screen and paper was conducted. State-of-the-art TFT-LCDs enable unimpaired reading, but a book-like positioning of screens seems necessary to minimise eyestrain symptoms. [ABSTRACT FROM AUTHOR]

Background: In the last years, there has been an increase in publication of systematic reviews of normative ("argument-based") literature or of normative information (such as ethical issues) in bioethics. The aim of a systematic review is to search, select, analyse and synthesise literature in a transparent and systematic way in order to provide a comprehensive and unbiased overview of the information sought, predominantly as a basis for informed decision-making in health care. Traditionally, one part of the procedure when conducting a systematic review is an appraisal of the quality of the literature that could be included., Main Text: However, while there are established methods and standards for appraising e.g. clinical studies or other empirical research, quality appraisal of normative literature (or normative information) in the context of a systematic review is still rather a conundrum - not only is it unclear how it could or should be done, but also the question whether it necessarily must be done is not settled yet. Based on a pragmatic definition of "normative literature" as well as on a typology of different types of systematic reviews of normative literature/information, this paper identifies and critically discusses three possible strategies of conducting quality appraisal., Conclusions: The paper will argue that none of the three strategies is able to provide a general and satisfying solution to the problems associated with quality appraisal of normative literature/information. Still, the discussion of the three strategies allows outlining minimal conditions that elaborated strategies have to meet in future, and facilitates sketching a theoretically and practically promising strategy.

Background: Psychosocial factors in cardiovascular diseases are increasingly acknowledged by patients, health care providers and payer organizations. Due to the rapidly increasing body of evidence, the German Cardiac Society has commissioned an update of its 2013 position paper on this topic. The German version was published in 2018 and the current manuscript is an extended translation of the original version., Methods: This position paper provides a synopsis of the state of knowledge regarding psychosocial factors in the most relevant cardiovascular diseases and gives recommendations with respect to their consideration in clinical practice., Results: Psychosocial factors such as low socioeconomic status, acute and chronic stress, depression, anxiety and low social support are associated with an unfavorable prognosis. Psychosocial problems and mental comorbidities should be assessed routinely to initiate targeted diagnostics and treatment. For all patients, treatment should consider age and gender differences as well as individual patient preferences. Multimodal treatment concepts should comprise education, physical exercise, motivational counseling and relaxation training or stress management. In cases of mental comorbidities, brief psychosocial interventions by primary care providers or cardiologists, regular psychotherapy and/or medications should be offered. While these interventions have positive effects on psychological symptoms, robust evidence for possible effects on cardiac outcomes is still lacking., Conclusions: For coronary heart disease, chronic heart failure, arterial hypertension, and some arrhythmias, there is robust evidence supporting the relevance of psychosocial factors, pointing to a need for considering them in cardiological care. However, there are still shortcomings in implementing psychosocial treatment, and prognostic effects of psychotherapy and psychotropic drugs remain uncertain. There is a need for enhanced provider education and more treatment trials.

Background: Some of the advantages of implementing electronic emergency department information systems (EDIS) are improvements in data availability and simplification of statistical evaluations of emergency department (ED) treatments. However, for multi-center evaluations, standardized documentation is necessary. The AKTIN project ("National Emergency Department Register: Improvement of Health Services Research in Acute Medicine in Germany") has used the "German Emergency Department Medical Record" (GEDMR) published by the German Interdisciplinary Association of Intensive and Emergency Care as the documentation standard for its national data registry., Methods: Until March 2016 the documentation standard in ED was the pen-and-paper version of the GEDMR. In April 2016 we implemented the GEDMR in a timeline-based EDIS. Related to this, we compared the availability of structured treatment information of traumatological patients between pen-and-paper-based and electronic documentation, with special focus on the treatment time., Results: All 796 data fields of the 6 modules (basic data, severe trauma, patient surveillance, anesthesia, council, neurology) were adapted for use with the existing EDIS configuration by a physician working regularly in the ED. Electronic implementation increased availability of structured anamnesis and treatment information. However, treatment time was increased in electronic documentation both immediately (2:12 ± 0:04 h; n = 2907) and 6 months after implementation (2:18 ± 0:03 h; n = 4778) compared to the pen-and-paper group (1:43 ± 0:02 h; n = 2523; p < 0.001)., Conclusions: We successfully implemented standardized documentation in an EDIS. The availability of structured treatment information was improved, but treatment time was also increased. Thus, further work is necessary to improve input time.

Objective: We conducted a trial embedded within the German National Cohort comparing the responses to study invitations sent in recycled envelopes of grey color vs. envelopes of white color. We analyzed paradata for reactions to the invitation letters by potential subjects, the duration between mailing date of the invitation and active responses, and study participation., Results: Grey envelopes only slightly increased the chance of active responses (OR 1.16, 95% CI 0.83, 1.62) to the invitation letter. Potential study subjects with German nationality (OR 3.75, 95% CI 2.07, 7.66) and age groups above 50 years (50-59: OR 1.78, 95% CI 1.19, 2.69; 60-69: OR 2.25, 95% CI 1.48, 3.43) were more likely to actively respond to the invitation letter. The duration between mailing date of the invitation and active response was not associated with envelope color, sex, nationality, or age. Our trial replicates previous observations that the color of the envelope of a study invitation does not influence the likelihood of an active response or study participation.

The regulations for ability to drive with cerebrovascular diseases in the German Driving License Regulations (Fahrerlaubnisverordnung, FeV) and German Guidelines for the Evaluation of Driving Ability of the Federal Highway Research Institute (BASt) are not up to date with the current medical knowledge and are not consistent with comparable regulations regarding cardiovascular diseases. This is particularly true for the assessment of future risks for a sudden loss of control during driving. The present position paper of six medical and neuropsychological societies in Germany presents the current conditions for the assessment of driving ability of patients a cerebrovascular diesease and recommends an estimation of the ability to drive founded on the current state of scientific knowledge. It addresses the following: 1. Physical and mental functional limitations and the possibilities for compensation, which if necessary enable a fitness to drive under conditions or within limits, including the importance of behavioral or personality changes and cognitive deficiencies that interfere with safety. 2. The potential danger due to a sudden loss of control as a result of a transient ischemic attack (TIA) new stroke event, or another cardiovascular event while driving. A summary in the form of a table provides physicians and expert assessors with assistance for the most important cerebrovascular diseases.

Thanks to multiple recirculation of process water, the German paper industry has succeeded in decreasing the specific fresh water demand from an average of 50 m3/t thirty years ago to 13 m3/t today. Although the increasing closure of white water loops creates many problems, it is bound to be part of the German paper industry's ongoing development. For a few years, in the production of packaging paper, two paper mills have been running with a totally closed water system including different process water treatment plants as 'kidneys'. This paper presents a comprehensive survey of the pros and cons of closed process water systems followed by significant examples of effluent-free production of corrugating medium and test liner. Additionally, operation experiences and economic aspects are discussed.

Social norm interventions hold the potential to change people's behavior. Five field experiments (N = 1,163) examined the effects of a simple and easily realizable social norm nudge based on the social media format "Be like Bill." The nudge consisted of a stick figure named Toni that communicated descriptive and injunctive norms regarding pro-environmental or pro-social behaviors. Nudge conditions were compared to no-intervention control conditions. Experiment 1 (N = 179) focused on paper towel consumption in a women's restroom at a German university. The nudge condition used less paper towels than the control condition, d = 0.48. Experiment 2 (N = 183) replicated this result (d = 0.32) in a more diverse setting of a women's restroom at a German Christmas market. Experiment 3 (N = 250) examined differences in the effects of prescriptive (i.e., 'do-norm') versus proscriptive (i.e., 'do not-norm') social norms on paper towel consumption again in a university women's restroom. The effectiveness of both social norm nudge conditions was shown in comparison to the control condition (d = 0.46; d = 0.40), while the prescriptive and proscriptive social norm manipulations did not differ. Experiment 4 (N = 206) applied the nudging approach to the use of plastic lids in a coffee shop, where no effect was found. Finally, Experiment 5 (N = 345) focused on the pro-social behavior of mask wearing in a bakery toward the end of the Covid-19 pandemic restrictions in Germany. In the nudge condition, more visitors put on face masks compared to the control group, d = 0.39. Limitations and contextual factors regarding the applicability of our social norm nudge are discussed.

Background: The Syria crisis has forced more than 4 million people to leave their homeland. As a result, in 2016, an overwhelming number of refugees reached Germany. In response to this, it was of utmost importance to set up refugee camps and to provide humanitarian aid, but a health surveillance system was also implemented in order to obtain rapid information about emerging diseases. Objective: The present study describes the effects of using digital paper and pen (DPP) technology on the speed, sequence, and behavior of epidemiological documentation in a refugee camp. Methods: DPP technology was used to examine documentation speed, sequence, and behavior. The data log of the digital pens used to fill in the documentation was analyzed, and each pen stroke in a field was recorded using a timestamp. Documentation time was the difference between first and last stroke on the paper, which includes clinical examination and translation. Results: For three months, 495 data sets were recorded. After corrections had been made, 421 data sets were considered valid and subjected to further analysis. The median documentation time was 41:41 min (interquartile range 29:54 min; mean 45:02 min; SD 22:28 min). The documentation of vital signs ended up having the strongest effect on the overall time of documentation. Furthermore, filling in the free-text field clinical findings or therapy or measures required the most time (mean 16:49 min; SD 20:32 min). Analysis of the documentation sequence revealed that the final step of coding the diagnosis was a time-consuming step that took place once the form had been completed. Conclusions: We concluded that medical documentation using DPP technology leads to both an increase in documentation speed and data quality through the compliance of the data recorders who regard the tool to be convenient in everyday routine. Further analysis of more data sets will allow optimization of the documentation form used. Thus, DPP technology is an effective tool for the medical documentation process in refugee camps.

The case of the highly restricted writings of the philosopher Martin Heidegger raises interesting issues of archival access and publication as they are affected by questions of privacy and publicity, history and responsibility, collective memory, the author's intentions, the demands of scholars, and general archival policies. After Heidegger bequeathed his considerable legacy of unpublished papers, lecture notes, and correspondence to the Deutsches Literaturarchiv in Marbach, Germany, his son, Hermann Heidegger, became his literary executor. With only rare and seemingly arbitrary exceptions, Hermann has not allowed any scholar to view unpublished materials within the archives. Restrictions on the collection stipulate that no scholar can view any of Heidegger's texts until they are published, and the publication schedule is incomplete, exceedingly protracted, and prone to long delays. Meanwhile, scholars of Heidegger bemoan the fact that thousands of pages of his philosophy remain "still unpublished, and not even planned for publication, but just gathering dust at the Marbach Archives." These facts of the case show the complexity of the issues surrounding archival policy for public intellectuals such as Heidegger. Even if an archival institution has developed a firm set of basic principles by which to permit access in a reasonable and equitable manner, the restrictions imposed by donors can supersede an institution's own best practices.
