National oral health survey on refugees in Germany 2016/2017: caries and subsequent complications
(2020)
Objectives To assess oral health, caries prevalence, and subsequent complications among recently arrived refugees in Germany and to ompare these findings with the German resident population. Methods This multicenter cross-sectional study recruited 544 refugees aged 3–75+ years; they were examined at ten registration institutions in four federal states in Germany by two calibrated dentists. The refugees were screened for caries (dmft/DMFT) and its complications pufa/PUFA); this data was compared to the resident population via the presentative national oral health surveys). Results The deciduous dentition of the 3-year-old refugees had a mean dmft value of 2.62 ± 3.6 compared with 0.48 dmft in the German resident population, and caries increased to 5.22 ± 3.4 for 6–7-year-olds (Germany: 1.73 dmft). Few refugee children had naturally healthy teeth (7% in 6–7-year-olds, Germany: 56%). In the permanent dentition, the gap in caries prevalence between refugees and the German population decreased with age (35–44-year-olds: 10.55 ± 7.1 DMFT; Germany: 11.2), but refugees exhibited more caries defects (35–44-year-olds DT = 3.13 ± 3.0; Germany: 0.5). German residents had more restorations (35–44-year-olds FT = 4.21 ± 4.6). Regarding complications, the 6–7-year-olds exhibited the highest pufa index (0.86 ± 1.4) which decreased in adolescence (13–17-year-olds, 0.18 ± 0.6) and increased in adults (45–64-year-olds, 0.45 ± 0.8). Conclusion The refugees had high caries experience, often untreated caries teeth and more complications compared with the German resident population, especially in children. Closing this gap by extending preventive systems to the refugees would decrease future treatment needs. Clinical relevance European countries should be prepared for the higher dental treatment needs in recent refugees, especially in
children.
Background: Restorative treatment for children’s teeth is still an important aspect of dentistry. In the light of an only moderate caries decline in the primary dentition and a persistently low care index in Germany during the past years [DAJ 2010], there is still a demand for further work on recent patterns and outcomes of restorative treatments in primary teeth placed in everyday practices under the Germany National Health System. Objectives: The present study aimed firstly to describe the prevalence of caries and restorations in the primary teeth in Berlin and Germany from the representative Germany surveys [DAJ 2010], secondly, to describe the frequency and distribution of restorative treatment in primary teeth performed in everyday dental practice in Berlin including children age groups from 1- to 13-years of age, thirdly, to evaluate the outcomes of restorative treatment performed in everyday dental practices in these children and finally to compare results of the present study with data from the German National Health System [KZBV 2011] and randomized community data on the longevity of restorations in primary teeth in Denmark [Qvist et al. 2010a]. Material and Methodology: In the first part of present study data from representative German surveys [DAJ 2010] were interpreted to describe and compare the prevalence of caries and restorations in the primary teeth in Berlin and Germany. For the second and third parts data generated from German National Health System in Berlin (KZV-Berlin) on fillings done in everyday practices in primary teeth of 1- to 13-year-olds during 2010/2011 were collected. This data included: distribution of children with dental treatment regardless of the type of intervention provided, of children who received restorative treatments in primary teeth during dental care visits including total number of fillings per child, the number of filled tooth surfaces, retreatment with another filling, stainless steel crowns, pulp involvement and extractions after prior filling therapy. Information on the age of the original fillings at the time of retreatment was also included. The collected data then were entered into a data base for descriptive and analytical analysis. The results were compared with equivalent data from the German National Health System [KZBV 2011] and randomized community data from Denmark [Qvist et al. 2010a]. Results: Result showed a high similarity in patterns of caries and restorative treatment in primary teeth in Berlin and all of Germany as reported in the representative German surveys [DAJ 2010]. About of 84% of 1-13-year-olds insured in the German National Health System in Berlin received dental care during 2010/2011, with considerably lower rates in very young children. Fillings in primary teeth were performed in 31.17% of all children attending the dentist. Most restorations were placed in 5-8-year-olds. In 1-13-year-olds mostly just one filling was placed, more than five fillings were per child were recorded on average for very young age groups (1-4-year-olds). 55.60% of all fillings in primary teeth were two-surface restorations, whereas more than three-surface restorations comprised 6.17% of all fillings and they were performed most frequently in young children of 1-4-years of age. Retreatment to fillings in primary teeth was 7.66% of fillings placed in 1-13-year-olds. Most retreatments took place from 5 to 9 years of age with a peak in 6-year-olds. In 1-3-year-old children fillings showed shorter mean age at the time of retreatment compared to 7-year-olds and above. Retreatment of fillings in primary teeth by stainless steel crowns was very limited with only 5.16% of all retreatments and it was preferred in children from 3 to 7 years of age. The retreatment with pulp involvement was 11.27% of all retreatments. Extractions were almost as often as retreatment as another filling (ratio 4:5), but they were preferred in older children due to the course of exfoliation. Conclusions: Under the conditions of this retrospective study, the restorative treatment with fillings performed within the National Health System in primary teeth in Berlin was very successful with low rates of retreatment and the fillings shows comparable results to data on the longevity of restorations in primary teeth in Denmark. The study highlighted the need to a structured program for prevention in primary teeth, especially for very young children with high caries activity and possibly also different treatment structures with specialized dentists in this field who can perform oral rehabilitations with pulpotomies and stainless steel crowns.
Trade of cattle between farms forms a complex trade network. We investigate partitions of this network for cattle trade in Germany. These partitions are groups of farms with similar properties and they are inferred directly from the trade pattern between farms. We make use of a rather new method known as stochastic block modeling (SBM) in order to divide the network into smaller units. SBM turns out to outperform the more established community detection method in the context of disease control in terms of trade restriction. Moreover, SBM is also superior to geographical based trade restrictions and could be a promising approach for disease control.

Die Idee von UNESCO-Biosphärenreservaten besteht darin, den Erhalt der biologischen Vielfalt mit der nachhaltigen Regionalentwicklung unter Beteiligung der Bevölkerung zu verbinden. Inwiefern die Idee unterstützt und in der eigenen Lebensweise berücksichtigt wird, wurde exemplarisch für die Bürgermeisterinnen und Bürgermeister aus drei Regionen analysiert. In Deutschland sind die UNESCO-Biosphärenreservate im Bundesnaturschutzgesetz rechtlich gesichert und gehören in den Zuständigkeitsbereich der Landesumweltministerien. Damit fehlt es ihnen oftmals an Zuständigkeiten, Personal und Geldern über naturschutzfachliche Themen hinaus. Mit dem Auftrag der Gewerbeförderung und dem Ausbau der Infrastruktur ergänzen die Gemeinden die naturschutzfachlichen Kompetenzen der deutschen UNESCO-Biosphärenreservate. Daher ist eine Zusammenarbeit für den Erfolg entscheidend. Die Forschungsfrage lautet somit: Wie ist die Idee der UNESCO-Biosphärenreservate in dem Wissen, den Einstellungen und dem Handeln der Bürgermeisterinnen und Bürgermeister aus den UNESCO-Biosphärenreservaten Schaalsee, Schorfheide-Chorin und Südost-Rügen verankert? Den Anforderungen der qualitativen Sozialforschung entsprechend, wurden die Bürgermeisterinnen und Bürgermeister der drei UNESCO-Biosphärenreservate 2010 interviewt. Das neuartige Konzept Verankerung der UNESCO-Biosphärenreservats-Idee bei Bürgermeisterinnen und Bürgermeistern ergab sich aus einem abduktiven Forschungsprozess: Er bestand aus einem Wechselspiel zwischen der Analyse von 45 leitfadengestützten Interviews nach der Grounded-Theory-Methodologie und dem Studium der sozialwissenschaftlichen Forschungen zu Akzeptanz, Partizipation und Governance in Schutzgebieten. Das Konzept Verankerung umfasst drei Dimensionen: Wissen, Einstellung und Handeln. Diese wurden mit jeweils vier bis fünf Kategorien gefüllt, die durch die explorative Analyse der Interviews identifiziert wurden. Orientiert an der Gesamtbeurteilung der Vor- und Nachteile des UNESCO-Biosphärenreservates vor Ort konnten die Bürgermeisterinnen und Bürgermeister in fünf unterschiedliche Typen der Verankerung unterteilt werden: Für die Unterstützer bringt das Biosphärenreservat vor Ort deutlich mehr Vorteile als Nachteile. Sie verfügen über umfangreiches Wissen zum Biosphärenreservat und zeigen eine hohe Eigeninitiative zur Umsetzung der Biosphärenreservats-Idee. Für die Befürworter überwiegen ebenso die Vorteile gegenüber den Nachteilen, jedoch nicht so deutlich wie bei den Unterstützern. Sie wissen weniger genau über das Biosphärenreservat vor Ort Bescheid, beteiligen sich aber bei Projekten der Biosphärenreservats-Verwaltung. Für die Unentschiedenen sind die Vor- und Nachteile des Biosphärenreservates ausgewogen. Sie kennen im Prinzip die Aufgaben von Biosphärenreservaten, konkrete Aktivitäten vor Ort sind ihnen aber kaum bekannt. Bei formellen Beteiligungsverfahren haben sie negative Erfahrungen in der Zusammenarbeit mit der Biosphärenreservats-Verwaltung gemacht. Sie loben jedoch einzelne Projekte. Für die Kritiker überwiegen die Nachteile gegenüber den Vorteilen des Biosphärenreservates. Sie bemängeln die Beteiligung der Gemeinden bei der Ausweisung des Biosphärenreservates als unzureichend und beanstanden die Zusammenarbeit mit der Biosphärenreservats-Verwaltung in formellen Beteiligungsverfahren. Sie sind Einheimische und haben im Alltag sehr starke Einschränkungen durch das Biosphärenreservat erfahren. Die Unbeteiligten können weder Vor- noch Nachteile des Biosphärenreservates benennen. Sie wissen kaum etwas über die Aktivitäten der Biosphärenreservats-Verwaltung und arbeiten selten mit ihr zusammen. In der komparatistische Analyse der Typen in den drei Biosphärenreservaten zeigen sich folgende Unterschiede: Im Biosphärenreservat Schaalsee sind die meisten Unterstützer und Befürworter zu finden, so dass dort die Biosphärenreservats-Idee am stärksten bei den Bürgermeisterinnen und Bürgermeistern verankert ist. Im Gegensatz dazu sind im Biosphärenreservat Südost-Rügen die meisten Kritiker. Im Biosphärenreservat Schorfheide-Chorin ist der Anteil der Unentschiedenen am größten. Diese Unterschiede sind eine Momentaufnahme und unterliegen einem ständigen Wandel. Da es durch die Kommunalwahlen regelmäßig zu neuen Konstellationen kommt, sollte diese Untersuchung nach jeder Wahl wiederholt werden. Die Ergebnisse können nicht mit der Verankerung der Biosphärenreservats-Idee bei der Bevölkerung gleichgesetzt werden, wie eine Gegenüberstellung mit den Ergebnissen einer Bevölkerungsbefragung aus 2010 gezeigt hat. Alles in allem liefert das Konzept Verankerung der Biosphärenreservats-Idee und die Differenzierung der Bürgermeisterinnen und Bürgermeister in Typen der Verankerung einen neuen Ansatz zur Analyse von Stakeholdern im Schutzgebietsmanagement. Es gibt dem Management eine bessere Handlungsorientierung: Es geht darum, eigenverantwortliches Handeln der Bürgerinnen und Bürger differenziert anzuregen und zu unterstützen.

Perception of climate change-related forest dieback in mountain forests among the local population
(2023)
Mountain forests provide multiple benefits but are threatened by climate change-induced forest dieback. Although many studies summarize perceptions of forest ecosystem services, relatively few deal with mountain forests. The local population’s perception of forest dieback in mountain forests in relation to climate change has rarely been investigated so far. Their perspective is relevant as local people are often deeply attached to “their” forests, they actively use forest ecosystems and—as voters and taxpayers—they need to support the state’s adaptation and funding measures. Therefore, this study investigates the climate change and forest dieback perception of local inhabitants in two mountain areas of Southern Germany (the German Alps and the Bavarian Forest) with a quantitative survey based on representative online samples (n = 709). Relying conceptually on van der Linden’s (J Environ Psychol 41:112–124, 2015. https://doi.org/10.1016/j.jenvp.2014.11.012) climate change risk perception model, the results show that experiential processing, cognitive and socio-cultural factors are related to locals’ forest dieback and climate change perception, while socio-demographics show no or few connections. Nearly two-thirds (64.7%) of the respondents perceive moderate to strong forest dieback, while more than half (55.0%) of the respondents already observe consequences of climate change. The perceptions of climate change and forest dieback are positively correlated with medium to high strength. This shows that forest dieback could be interpreted as an indicator of climate change, which is difficult to observe due to its long-term nature. We identify three groups of respondents regarding preferred forest adaptation strategies to climate change. In general, respondents support nature-based forest adaptation strategies over intense measures.
Knowledge on differences in the severity and symptoms of infections with the SARS-CoV-2 Omicron variants BA.2 (Pango lineage B.1.529.2) and BA.5 (Pango lineage B.1.529.5) is still scarce. We investigated epidemiological data available from the public health authorities in Mecklenburg-Western Pomerania, Northeast Germany, between April and July 2022 retrospectively. Comparative analyses revealed significant differences between recorded symptoms of BA.2 and BA.5 infected individuals and found strong correlations of associations between symptoms. In particular, the symptoms ‘chills or sweating’, ‘freeze’ and ‘runny nose’ were more frequently reported in BA.2 infections. In contrast, ‘other clinical symptoms’ appeared more frequently in Omicron infections with BA.5. However, the results obtained in this study provide no evidence that BA.5 has a higher pathogenicity or causes a more severe course of infection than BA.2. To our knowledge, this is the first report on clinical differences between the current Omicron variants BA.2 and BA.5 using public health data. Our study highlights the value of timely investigations of data collected by public health authorities to gather detailed information on the clinical presentation of different SARS-CoV-2 subvariants at an early stage.
