Background. The pandemic situation of the novel coronavirus (severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)) and its associated disease (coronavirus disease 2019 (COVID-19)) represents a challenging condition with a plethora of aspects. The course of COVID-19 in patients with immune-mediated inflammatory diseases (IMID) such as inflammatory bowel disease (IBD) and rheumatic diseases (RD) is not well known. Our study is one step toward closing this gap by collecting data on vaccination rates, infection-free survival, and individual symptom severity. Methods. We conducted a prospective questionnaire-based study between April 2022 and October 2022 at our university hospital. Outward patients over the age of 18 years were screened for participation and reported about their infection/infection-free survival since the start of the pandemic. Results. Finally, 156 patients were included in the study, 117 (75.0%) of which had inflammatory bowel disease and 39 (25.0%) patients with rheumatic disease. Altogether, 143 (91.7%) persons had received at least one vaccination against SARS-CoV-2. A total of 153 patients provided information regarding their COVID-19 history: 81 patients (52.0%) self-reported about their SARS-CoV-2 infection. In general, courses of infection were mild: only two patients (2.5% of patients with reported COVID-19) were hospitalized due to COVID-19 with one (1.2%) of the two needing intensive care. Asymptomatic COVID-19 had been described by 7 persons (8.6% of patients with reported COVID-19). Acute COVID-19 was accompanied by fatigue/tiredness in 58 persons (71.6% of patients with history of COVID-19) as the most frequent symptom. Other complaints were common cold (55 patients = 67.9%), cough (51 patients = 63.0%), headache (44 patients = 54.3%), and fever (35 patients = 43.2%). Stratified by vaccination status (unvaccinated vs. at least once vaccinated), the time to infection differed significantly (logrank test: p = 0.04 , Chi2 4.1). At least once vaccinated people had a median COVID-19-free survival of 28.5 months (confidence interval (CI): 23.6 months-not reached). Without any vaccination, the estimated time to infection was 25.1 months (CI: 23.6 months-not reached). Conclusion. Our IMID patients have a high rate of vaccination against SARS-CoV-2. Data show a significantly longer infection-free survival in vaccinated IMID patients as compared to unvaccinated patients. Discrimination between symptoms of COVID-19 and a concomitant inflammatory disease is difficult as complaints might be overlapping. This trial is registered with DRKS00028880. [ABSTRACT FROM AUTHOR]

Introduction: Despite various efforts to reduce nitrogen leaching from agricultural land, the permissible nitrate concentrations in groundwater have often been exceeded in the past. Intensive farming is often seen as the cause of the deterioration in water quality. Therefore, the present lysimeter study aimed to quantify nitrogen (N) leaching at different N fertilization levels for the agricultural land use systems of arable land and grassland to derive suitable management measures for improving groundwater quality. Methods: The effects of three different of mineral fertilization treatments (50%, 100%, and 150%) in arable land and grassland use on four distinct soil types (loamy sand, sand, loam, loess) concerning seepage formation, nitrogen concentrations, nitrogen loads, drymatter yields and nitrogen balances were tested. The study was conducted at the lysimeter facility of the Helmholtz Centre of Environmental Research - UFZ at Falkenberg (northeast Germany). Twenty-four non-weighable lysimeters with a surface area of 1 m² and a depth of 1.25 m were managed as grassland and arable land with three different fertilization treatments since 1985. Results and Discussion: For arable land use, N leaching differed between the studied soil types, with the highest N loads from the sand (36.6 kg ha-1 yr-1) and loamy sand (30.7 kg ha-1 yr-1) and the lowest N loads fromloess (12.1 kg ha-1 yr-1) and loam soil (13.1 kg ha-1 yr-1). In contrast to grassland use, a reduction of N fertilization level by 50 % did not result in reduced N leaching for arable land, whereas a maximal 29% reduced dry matter yields was observed. An increase of N fertilization by 50 % did not cause significant enhanced N leaching at arable land use. Soil-and management-related factors (soil type, texture, soil tillage, crop rotation, and others)mask the effect of increased N fertilization rates in arable land using lysimeters. For arable land use, a reduction of N fertilizer levels as the only measure was insufficient to reduce NO3- leaching, and other strategies besides N fertilization levels are required to improve groundwater quality. Measures should be targeted to reduce N losses by mineralization processes. [ABSTRACT FROM AUTHOR]

The stillbirth, mummification, embryonic death, and infertility (SMEDI) syndrome is most commonly associated with porcine parvovirus 1 (PPV1) infections. Little is known about the occurrence of coinfections with SMEDI-associated pathogens and the associations among these pathogens. In our study, we included 40 SMEDI-affected litters from 18 different farms. In total, 158 out of 358 available fetuses from diagnostic transmittals were selected by systematic random sampling and examined for PCV2, PCV3, PPV1, and Leptospira spp. by q-PCR. Results from diagnostic materials showed the following results: in eleven farms, PCV2 was present; in nine farms, PPV1 was present; in five farms, PCV3 was present; and in two farms, Leptospira spp. was present. The detection of Leptospira spp. was significantly associated with a PCV2 coinfection (OR: 26.3; p < 0.001). PCV3 positivity resulted in a reduced probability of detecting PCV2 in the corresponding fetus (OR: 0.078; p = 0.008). Fetal maceration was associated with Leptospira spp. detection (OR: 8.6; p = 0.003), whereas mummification (p = 0.047), reduced crown-rump length (p < 0.001), and bodyweight (p = 0.001) of fetuses were significantly associated with PPV1 and PCV2 coinfection and thus, presumably, a shorter time to death after infection, indicating an enhanced negative effect on the development of fetuses with PCV2 + PPV1 coinfection.

Histomonosis has become an important disease of turkeys since the ban of effective feed additives and therapeutics. Some critical risk factors for pathogen introduction into a farm have already been identified but open questions remain. Therefore, a retrospective case–control-study was used to identify the most significant risk factors for Histomonas (H.) meleagridis-introduction into a turkey farm. A total of 113 questionnaires were collected from 73 control-farms and 40 Histomonas-positive case-farms in Germany between 20 April 2021 and 31 January 2022. The data were analysed for possible risk factors by descriptive and univariate, single- and multi-factorial analysis. The presence of earthworms, snails and beetles, as vectors of H. meleagridis, as well as the proximity to other poultry-keeping farms in addition to a frequent observation of wild birds nearby the turkey farm, showed the highest risk potential for histomonosis outbreaks. Furthermore, poor biosecurity measures seem to have increased the probability for an outbreak. Insufficient climate management, straw as litter material and an inadequate litter refill frequency might have promoted a favourable humidity for vector- or pathogen survival providing important areas for improved disease control measures in the future. A retrospective case–control-study was conducted to identify impactful risk factors for a H. meleagridis introduction. The probability of a histomonosis outbreak was increased by the presence of vectors and reservoirs nearby a farm. Impactful risk factors concerning biosecurity measures, climate and litter management were identified. [ABSTRACT FROM AUTHOR]

Porcine epidemic diarrhea virus (PEDV), belonging to the genus Alphacoronavirus, can cause serious disease in pigs of all ages, especially in suckling pigs. Differences in virulence have been observed between various strains of this virus. In this study, four pigs were inoculated with PEDV from Germany (intestine/intestinal content collected from pigs in 2016) and four pigs with PEDV from Italy (intestine/intestinal material collected from pigs in 2016). The pigs were re-inoculated with the same virus on multiple occasions to create a more robust infection and enhance the antibody responses. The clinical signs and pathological changes observed were generally mild. Two distinct peaks of virus excretion were seen in the group of pigs inoculated with the PEDV from Germany, while only one strong peak was seen for the group of pigs that received the virus from Italy. Seroconversion was seen by days 18 and 10 post-inoculation with PEDV in all surviving pigs from the groups that received the inoculums from Germany and Italy, respectively. Attempts to infect pigs with a swine enteric coronavirus (SeCoV) from Slovakia were unsuccessful, and no signs of infection were observed in the inoculated animals. [ABSTRACT FROM AUTHOR]

Vertical transmission is a consistently discussed pathway of porcine circovirus type 2 (PCV2) and porcine circovirus type 3 (PCV3) transmission in pigs. To evaluate the presence of PCV2 and PCV3 in piglets, we collected tissue samples from 185 piglets that were crushed within the first week of life from 16 farms located in Germany and Austria. Pooled samples consisting of thymus, inguinal lymph node, myocardium, lung and spleen were examined for PCV2 and PCV3 by qPCR. Furthermore, oral fluid samples (OFS) from grow–finish pigs were collected and examined the same way. In piglets, PCV2 was highly prevalent (litters: 69.4%; piglets: 61.6%), whereas PCV3 prevalence was low (litters: 13.4%; piglets: 13.0%). In total, 72.6% and 67.2% of all collected OFS were PCV2 or PCV3 positive, respectively. Sow vaccination against PCV2 was identified as a protective factor concerning PCV2 in piglets (OR: 0.279; CI: 0.134–0.578; p < 0.001), whereas the porcine reproductive and respiratory syndrome virus (PRRSV) vaccination of sows was identified as a protective factor concerning PCV3 in piglets (OR: 0.252 CI: 0.104–0.610; p = 0.002). Our results show that PCV2, but not PCV3, is ubiquitous in suckling piglets and that early PCV3 infections might be modulated by PRRSV–PCV3 interaction. However, the ubiquitous nature of both viruses in older pigs could be confirmed. [ABSTRACT FROM AUTHOR]

This paper focuses on the structure and extent of wage differences among graduates of different higher-education institutions in Germany. We ask how large these differences are and how they relate to fields of study and regional labour markets. The results from our application of cross-classified random-effects models to a cohort of the DZHW Graduate Panel show that there is a considerable amount of wage variation depending on the graduates' alma mater. However, this variation can be fully explained by structural characteristics: Selection based on individual characteristics is of only minor importance, while regional labour markets do matter. Most of all, however, the differences relate to fields of study. [ABSTRACT FROM AUTHOR]

This article compares two German-speaking Mennonite colonies in Paraguay and their encounters with Nazism during the 1930s. It focuses on their understandings of the Nazi bid for transnational völkisch unity. Latin America presents a unique context for studying the Nazis' relationship to German-speakers abroad because it held the allure of being the last prospect for German cultural and economic expansion, but was simultaneously impossible for the German state to invade. The Menno Colony was made up of voluntary migrants from Canada who arrived in Paraguay in the 1920s. The Fernheim Colony was composed of refugees from the Soviet Union who settled alongside the Menno Colony in the 1930s. Both groups shared a history in nineteenth-century Russia as well as a common faith and culture. Nevertheless, they developed radically different opinions about völkisch nationalism. The Menno Colony's communal understanding of Germanness made völkisch propaganda about Hitler's "New Germany" unappealing to their local sensibilities. They rejected all forms of nationalism as worldly attempts to thwart their cultural-religious isolationism. The refugees of Fernheim Colony, by contrast, shared little communal unity since they originated from diverse settlements across the Soviet Union. They viewed Germanness as a potential bridge to an imagined German homeland and believed that the highest goal of völkisch unity was to promote communal unity. Resembling other German-speaking communities in Latin America, the two colonies—which seemed identical to Nazi observers—held vastly different interpretations of völkisch nationalism at the height of the Nazi bid to establish transnational German unity in Latin America.

Many of the processes behind the decline of farmland birds can be related to modifications in landscape structure (composition and configuration), which can partly be expressed quantitatively with measurable or computable indices, i.e. landscape metrics. This paper aims to identify statistical relationships between the occurrence of birds and the landscape structure. We present a method that combines two comprehensive procedures: the 'landscape-centred approach' and 'guild classification'. Our study is based on more than 20,000 individual bird observations based on a 4-year bird monitoring approach in a typical agricultural area in the north-eastern German lowlands. Five characteristic bird guilds, each with three characteristic species, are defined for the typical habitat types of that area: farmland, grassland, hedgerow, forest and settlement. The suitability of each sample plot for each guild is indicated by the level of persistence (LOP) of occurrence of three respective species. Thus, the sample plots can be classified as 'preferred' or 'less preferred' depending on the lower and upper quartiles of the LOP values. The landscape structure is characterized by 16 different landscape metrics expressing various aspects of landscape composition and configuration. For each guild, the three landscape metrics with the strongest rank correlation with the LOP values and that are not mutually dependent were identified. For four of the bird guilds, the classification success was better than 80%, compared with only 66% for the grassland bird guild. A subset of six landscape metrics proved to be the most meaningful and sufficiently classified the sample areas with respect to bird guild suitability. In addition, derived logistic functions allowed the production of guild-specific habitat suitability maps for the whole landscape. The analytical results show that the proposed approach is appropriate to assess the habitat suitability of agricultural landscapes for characteristic bird guilds. [ABSTRACT FROM AUTHOR]

The article discusses the relationship between social integration and government postal services in the German States during the 19th century. Particular focus is given to evidence drawn from density maps depicting the total number of post offices in a given area. According to the author, the postal systems lessened regional and geographical barriers to integration. Capital cities and system topology are also discussed.

It has been argued that at the beginning of the twentieth century German colonial officials and travelers created a myth about the Bamum Kingdom of Cameroon. Fed by innumerable invocations of the grandeur of Bamum architecture, this myth celebrated the kingdom as the long-sought paradisiacal "Africa" of the Western imagination. In this article I argue that the Bamum narrative did not exist in opposition to any identifiable reality or essential truth. Instead, I suggest that the Bamum narrative, like the similarly mythologized narrative of Mousgoum architecture, should be understood in relation to the ideological conditions of its production, including emerging tropes, theories, and methods of argumentation in German ethnology that were themselves complicit in colonialism.

The present study reports on the development of ombrotrophic raised bogs in NE Germany after the adoption of a protective program with a focus on the hydrological and floristic changes in two simultaneously restored cut-over bogs as a reference for all other bogs. At the moment, four fifths of the bogs area is dominated by woody vegetation forms and <5 % is characterized by typical raised bog vegetation. The trend of increasing areas with woody vegetation forms and decreasing areas with vegetation typical for ombrotrophic raised bogs could not be prevented despite increasing the portion of revitalized areas. The reason for the negative developments is founded in the different types of raised bogs in NE Germany, which differ in regard to the historical lagg area and the original grown up raised peat body. This as well as the kind and intensity of anthropogenic use have significant implications for the possibilities of revitalization and protection. Except for those bogs where no peat remnants remain, the revitalization of cut-over raised bogs in NE Germany can succeed if an almost closed hydrological protection zone (HPZ which is equal to the historical lagg area) is established so that the gradient of entire lateral water flow between the higher lying peat remnant and the lower lying surrounding area is reduced. The attainment of a lateral water flow gradient comparable to the original state and of a water-saturated peat body succeeds in turn in the precondition for growing Sphagnum species, which readjust the system's self regulation. The comparison of two bogs with similar preconditions concerning location, climate, and anthropogenic transformation has shown that an incompletely closed HPZ is one important reason for the decreasing portion of intact raised bogs with their typical vegetation. The influence of climate change on current hydrological and floristic changes in NE German ombrotrophic raised bogs has less influence on the success of revitalization than the historic grown type of bog and the intensity of anthropogenic use.

This contribution presents the technique of conversive translation, which has yet to receive much attention in Germany. The concept focuses on the use of verbs in the target language that describe the action from a different point of view. The situation depicted remains recognizable despite the shift, and neither are text meaning nor authorial intention impaired. The technique is applied when the target language offers no semantic equivalents, rules and conventions prevent their use, or a clearer statement is possible. [ABSTRACT FROM AUTHOR]

The article discusses the relationship between physical anthropology and ethnology at the end of the 1920s, before the National Socialists came into power. It focuses on Leipzig, Germany, as the home of the Saxon Research Institute which funded ethnological expeditions during which physical anthropology was a focus of study. It discusses physical anthropology as meaning "racial science" at this time, and refers to the studies done during the expeditions of anthropologists Egon Freiherr von Eickstedt, Paul Germann, and Bernhard Struck. Also discussed is the importance of the cooperation between the two sciences as seen from the perspective of professor Fritz Krause at the University of Leipzig in 1929 and its significance for contemporary studies.

The article reviews the exhibition in Berlin, Germany, titled "Otherwise Come Into the World. The Humboldt Forum in the Castle. A Workshop View." The Forum focused on the state of the reconstruction of the Hohenzollern Castle to house relocating Dahlem, Germany, collections dedicated to ethnology. The article discusses the exhibition from ethnological content as well as museological and cultural studies viewpoints. The mission, expected inventory of objects, and completion dates for the new museum are also reviewed.

The article presents information regarding the history of images in ethnographic research and education. Particular attention is paid to ethnographic images from the period between 1869 and 1920, because of the institutional developments of the museums and universities that housed the images. It is noted that this time period also featured technological advancements that better enabled the recording, storing, and dissemination of ethnographic drawings, photographs, and prints. Further comments are made concerning the founding of the German ethnological periodical Zeitschrift für Ethnologie (ZfE), and a discussion is included on the work of German ethnographers Otto Finsch, Theodor Koch-Grünberg, and Karl von den Steinen.

Habitat size, habitat isolation and habitat quality are regarded as the main determinants of butterfly occurrence in fragmented landscapes. To analyze the relationship between the occurrence of the butterfly Cupido minimus and these factors, patch occupancy of the immature stages in patches of its host plant Anthyllis vulneraria was studied in the nature reserve Hohe Wann in Bavaria (Germany). In 2001 and 2002, 82 A. vulneraria patches were surveyed for the presence of C. minimus larvae. The occurrence was largely affected by the size of the food plant patches. In a habitat model that uses multiple logistic regression, the type of management and habitat connectivity are further determinants of species distribution. Internal and temporal validation demonstrate the stability and robustness of the developed habitat models. Additionally, it was proved that the colonization rate of C. minimus was significantly influenced by the distance to the next occupied Anthyllis patch. Concerning long-term survival of (meta-) populations in fragmented landscapes, the results show that lower habitat quality may be compensated by higher connectivity between host plant patches.

This study was carried out to discover whether an alternative growing from officinal and spice plants on grassland sites in the north eastern part of Germany is possible. To find suitable species, special botanical studies of large grassland areas were made and analysed. Furthermore, parcel experiments with different species as well as field experiments in farms were made. First of all, the common market species Petasites hybridus L., Valeriana officinalis L., Plantago lanceolata L. and Carum carvi L. are preferred, especially for lowland grassland sites with influence of groundwater. They are meant to reach a high yield level after ploughing of grassland. Moreover those species have quite good quality parameters. Sandy soils as well as organic stoneless ones offer suitable conditions concerning cleaning and working of the root mass. During the time of harvesting, increasing groundwater levels in wintertime have to be considered. [ABSTRACT FROM AUTHOR]

The aim of the study was to investigate the effects of peat soil substrate governed by the hydrological type of mire, land use and state of anthropogenic changes on the fen soil structure in terms of the water retention curve, soil aggregates and topsoil strength. Our hypothesis was that morphological parameters of the peat soil landscape, like peat thickness and water table, are correlated with functional parameters of internal soil structure like water retention or cone resistance. These parameters were measured along several transects in fens of the Rhin-Havelluch and the Uckermark region. Results confirmed our hypothesis. The peat thickness was cross-correlated with the state of anthropogenic soil changes and soil structure. The type of land use (grassland, forest) had significant implications for the moisture status and structure in terms of density, strength, pore size distribution and aggregate sizes of topsoils.

The foliage-dwelling spider fauna was collected in maize fields and on stinging nettles in adjacent margins in Bavaria, South Germany. Two different sampling methods were evaluated: drop cloth sampling and suction sampling. The overall catch was dominated by juvenile spiders, web-building spiders, and spiders of the families Theridiidae, Linyphiidae, Tetragnathidae and Araneidae (in decreasing order). Field margins harboured more species than maize fields, whereas the total spider abundance was higher in the maize crop. Web-building spiders such as Theridiidae and Linyphiidae were prominent in maize by individual numbers. Suction sampling with a small suction device proved to be a more efficient and consistent sampling method for foliage-dwelling spiders than drop cloth sampling. Density and species richness of foliage-dwelling spiders in maize was shown to be fairly high, implying that spiders of higher strata may play a more important role in biological control than suspected up to now.

This paper reports on the mixing of Euro coins from different countries of origin in Europe, which started on 1 January 2002. There is an interesting conclusion: that the mobility of small and large denominations is different. The long-term behaviour of the mixing process is studied using a simple deterministic model and data from Germany, France and the Netherlands. The analysis leads to predictions about the future progress of the mixing process. [ABSTRACT FROM AUTHOR]

In the absence of long-term records of soil erosion by land use change in the moraine landscape, NE-Germany, slope basis deposits offer considerable potential for reconstructing the changing soil erosion rates at a catena scale in response to the environmental change. A pit with a length of 61m and an average depth of 1.5 to 3m was opened along the catena, located 60km east of Berlin, NE Germany. The 137Cs and 210Pbex dating in conjunction with soil profile analysis methods were used to define a chronology for the accumulated soil materials at slope basis of the catena. The temporal patterns of sediment accumulation rates at study catena were subdivided into five time periods. The deposited depth of sediments in the slope basis has increased eight to ten - fold during the periods between 1954 and 1986 compared to the deposit depth over the past 600 years. Over the last 100 years, deposited depth at the slope basis of the catena increased from 0.49 cm/yr to 1.04 cm/yr and then decreased to 0.45 cm/yr. Increase in sedimentation rate in the time period from 1897 to 1986 corresponded to intensive agricultural tillage operations whereas a decrease in sedimentation after 1986 corresponded to a land use change from arable land to grassland of the study catena.

In Versuchen mit Grundwasserlysimetern wurde der Einfluß des Grundwasserstandes auf den Nährstoff‐haushalt und die Evapotranspiration nordostdeutscher Niedermoore geprüft. 1. In den Stickstoffteilbilanzen wird deutlich, daß tiefe Entwässerung in den Niedermooren die Auswaschungsverluste erhöht, was auf verstärkte oxydative Torfmineralisation hinweist. Da jedoch die Erträge bei tiefen Grundwasserständen geringer waren, unterscheiden sich die Endbilanzen nicht wesentlich. 2. Der Ertrag ist der Haupteinflußfaktor in den Kailumbilanzen. Der sehr hohe Entzug durch die Ernte bei geringer Entwässerung des Niedermoorbodens führte trotz beachtlicher Zufuhr über das simulierte Grundwasser zu hohen Fehlbeträgen in der Endbilanz. Die Grundwassernähe begünstigte folglich die Kaliumauswaschung. 3. Höhere Grundwasserstände steigern deutlich die Evapotranspiration. Die Ursachen liegen einerseits in einer verstärkten Evaporation, da der kapillare Aufstieg durch die Nähe des Wassers zur Oberfläche begünstigt wird. Andererseits nimmt in der Regel der Gräserertrag mit steigendem Grundwasserstand zu, was zusätzlich eine Erhöhung der Transpiration mit sich bringt. [ABSTRACT FROM AUTHOR]

Background: Porcine epidemic diarrhea (PED) is a viral enteric disease of pigs. It affects all age classes of animals but lethality is mainly seen in suckling piglets. After its first appearance in England in 1971, Porcine epidemic diarrhea virus (PEDV) has spread worldwide. While sporadic outbreaks prevailed in Europe, the disease had high impact in Asia. Following particularly severe outbreaks in 2011, high impact cases were also reported in the United States and neighboring countries in 2013. Subsequently, outbreaks were also reported in several European countries including Germany. These outbreaks were less severe. This case report describes a recent case of PED re-emergence in Germany and the sequence analyses of the causative PEDV. Case presentation: In spring 2019 5 years after re-introduction of PED into Central Europe, a piglet-producer in northwestern Germany experienced an outbreak that affected sows, their suckling piglets, and weaners. After initial confirmation of PEDV by real-time RT-PCR, fecal material and small intestine samples from affected pigs were subjected to metagenomic analyses employing next-generation sequencing. Phylogenetic analyses showed high identities among the PEDV sequences obtained from samples of different animals and a close relation to recent strains from Hungary and France. Compared to the PEDV strains analyzed in 2014, genetic drift could be confirmed. Changes were mainly observed in the spike protein encoding S gene segment. In addition, metagenomic analyses showed multiple Picobirnavirus reads in all investigated samples. Conclusion: This case report shows that PEDV is still circulating in Europe. The causative strains are moderately virulent and are still closely related to the so-called INDEL strains reported previously in Europe, including Germany. However, a genetic drift has taken place that can be seen in a novel cluster comprising strains from Germany, Hungary and France in 2019. Relevance and impact of the detected Picobirna sequences need further investigations. [ABSTRACT FROM AUTHOR]
