The bluefin tuna, Thunnus thynnus, is a highly migratory and long-living fish at the top of the pelagic food web. As top predator, it plays a key role in the stability of marine food webs by exerting top-down control on its prey. The diet composition of bluefin tuna varies in relation to its growth, seasons and migratory patterns, making it difficult to evaluate spatial and temporal effects. This latter aspect is further complicated to be determined during the first months of life, whenT. thynnusspecimens have a rapid growth rate leading to changes in the trophic status. In this study, the potential collagen-related effects on δ15N and δ13C values were evaluated on the whole spine of adult tuna specimens collected in the central Mediterranean Sea. Obtained results showed non-significant differences between extracted and non-extracted collagen samples for δ15N in whole spine, allowing adopting the isotopic analysis both forannuliin the spine section of adults and for younger specimens, whose spine size does not permit the collagen extraction. Specifically, isotopic analysis of whole spine of the young of the year specimens, showed a rapid change in δ15N values with length, following an exponential model. For older specimens, δ15N values were higher and varied around a plateau, likely due to a higher specificity in the choice of prey and/or to change in the geographical location. Such variability was also mirrored inannuliof spines sections of adult tunas. As far as δ13C values are concerned, a strong collagen-related effect was evidenced, likely highlighting the influence of lipids. Consequently, δ13C analysis may be used only on adult specimens where collagen extraction is possible. This research also showed how isotopic analysis of both whole sample and sequence ofannuliin the cross-section of dorsal spine might produce isotopic profiles useful to detect specific trophic dynamics along the bluefin tuna growth.

Published: June 2020

In Talbot-Lau interferometry, the sample position yielding the highest phase sensitivity suffers from strong geometric blur. This trade-off between phase-sensitivity and spatial resolution is a fundamental challenge in such interferometric imaging applications with either neutron or conventional x-ray sources due to their relatively large beam-defining apertures or focal spots. In this study, a deep learning method is introduced to estimate a high phase-sensitive and high spatial resolution image from a trained neural network to attempt to avoid the trade-off for both high phase-sensitivity and high resolution. To realize this, the training data sets of the differential phase contrast images at a pair of sample positions, one of which is close to the phase grating and the other close to the detector, are numerically generated and are used as the inputs for the training data set of a generative adversarial network. The trained network has been applied to the real experimental data sets from a neutron grating interferometer and we have obtained improved images both in phase-sensitivity and spatial resolution.
Enhanced Surface Plasmon Resonance Wavelength Shifts by Molecular Electronic Absorption in Far- and Deep-Ultraviolet Regions
Authors: Tanabe Ichiro , Tanaka Yoshito Y. , Watari Koji , Inami Wataru , Kawata Yoshimasa , Ozaki Yukihiro
Published: June 2020

In this study, surface plasmon resonance (SPR) wavelength shifts due to molecular electronic absorptions in the far-ultraviolet (FUV, < 200 nm) and deep-ultraviolet (DUV, < 300 nm) regions were investigated by attenuated total reflectance (ATR) spectroscopy. Due to the strong absorption in the DUV region, N,N-dimethylformamide (DMF) significantly increased the SPR wavelength shift of Al film. On the other hand, no such shift enhancement was observed in the visible region for Au film because DMF does not have absorbance compared to non-absorbing materials such as water and alcohols. The enhanced SPR wavelength shift, caused by the overlap between SPR and molecular resonance wavelengths in FUV-DUV region, is expected to result in high sensitivity for resonant materials.
Validation of barley 2OGO gene as a functional orthologue of Arabidopsis DMR6 gene in Fusarium head blight susceptibility
Authors: Low Yee Chen , Lawton Michael A. , Di Rong
Published: June 2020

Fusarium head blight (FHB) caused by Fusarium graminearum (Fg) is a devastating disease of crops, especially wheat and barley, resulting in significant yield loss and reduced grain quality. Fg infection leads to the production of mycotoxins, whose consumption is toxic to humans and livestock. The Arabidopsis DMR6 gene encodes a putative 2-oxoglutarate Fe(II)-dependent oxygenase (2OGO) and has been identified as a susceptibility factor to downy mildew. We generated site-specific mutations in Arabidopsis At2OGO by CRISPR/Cas9 gene editing. The resulting At2OGO knock-out (KO) mutants display enhanced resistance to Fg in a detached inflorescence infection assay. Expression profiling of defense genes revealed that impairment of At2OGO function resulted in the upregulation of defense genes that are regulated by salicylic acid (SA), jasmonic acid (JA) and ethylene (ET) pathways. Complementation of the At2OGO-KO lines with a barley (cv. Conlon) orthologue, Hv2OGO, restored susceptibility to Fg. This result indicates that the Hv2OGO gene is functionally equivalent to its Arabidopsis counterpart and, hence, may have a similar role in conditioning susceptibility to FHB in barley. These results provide a molecular basis for proposing 2OGO as a plant immunity suppressor in Arabidopsis and potentially in barley plants and establish a rationale and strategy for enhancing FHB resistance in barley.

Design and verification of a tunable metamaterial and its sensing application
Authors: Zhong Min
Published: June 2020

In this study, the authors present a single‐band tunable metamaterial absorber in the 3.00–6.00 THz region. This absorption peak (90.00% amplitude) is excited by the cavity resonance at the resonance frequency of 4.55 THz. The cavity resonance mode is achieved in the spacer cavity formed by the metal/strontium titanate (STO)/SU‐8 photoresist (SU‐8)/STO/metal layers. The effect of structural parameters on this absorption peak is measured in two groups of experiments. As the diameter of holes array D increases, the cavity resonance peak is enhanced to 94.00% and shifted to 4.79 THz. However, for the increase in the thickness of the SU‐8 layer T3, this peak is increased to 98.00% and moved to 3.88 THz. To verify the dual detection functions, two sets of experiments are carried out. In the third set of experiments, this absorption peak is increased to 99.80% and shifted to 5.60 THz with the increasing environmental temperature. In the fourth set of experiments, samples are covered by three liquids, and both the absorption amplitude and the resonance frequency are reduced. This tunable metamaterial absorber shows possibilities for applications in environmental temperature sensing and liquid sensing.
Technological Scheme of Complex Peat Processing for Obtaining of Multifunctional Hydrophobic and Hydrophilic Powders
Authors: Misnikov Oleg
Published: June 2020

The method of hydrophobic modification of dispersed materials is based on the extraction of bituminous components of peat and applying them to a treated surface. The industrial implementation of this method is possible in the following main directions. First, it is the thermochemical treatment in a reactor of the entire material volume by hydrophobic components of peat with a low concentration. Second, it is the obtaining of concentrated hydrophobically-modifying compositions and their use in the production technology of various types of powdered dispersed materials. Positive results were obtained with organo-mineral hydrophobically- modifying concentrates based on peat with clinker, kaolin, chalk, lime, vermiculite. Third, it is the use of the sorption properties of the porous structure of peat to saturate it with additional hydrophobic components: bitumen, oleic acid, organosilicon compounds, etc. The main advantage of the obtained composite hydrophobic modifiers is quality (accurate) dosing. There are promising directions of the use of hydrophobically-modifying additives in the construction industry, chemical industry and to ensure fire safety. A block diagram of the technological process of complex peat processing to produce hydrophobic and hydrophilic powders is proposed. Additional processing of production wastes allows for the production of a stabilizing additive for asphalt concrete.

Authors: Selyukov Alexei , Byrdin Kirill
Published: June 2020

The natural conditions for the formation of coal deposits in different regions of the globe are the same, all of them belong to reservoir sedimentary deposits and differ only in the degree of metamorphism and tectonic disturbances. In this regard, coal deposits of the Kuznetsk basin (Kuzbass, Western Siberia, Russia)) that have no analogues in nature are unique. Here are all sorts of options for the occurrence of coal seams both in terms of their thickness, dip angle, number, and the degree of disturbance by plicative and disjunctive disturbances. The article presents some results of research on ways to reduce coal losses in open pit mining during its extraction by draglines. The study was carried out on the example of deposits in Kemerovo region with coal seams in an inclined and steep formations, which allows analyzing the possibilities of applying the proposed technological solutions in the widest range of specific mining and geological conditions.

Construction of Buildings and Structures on Rock Concrete Compensation Slabs when Building in Subsided Areas of Abandoned Coal Mines and Open Pits
Authors: Uglyanitsa Andrey
Published: June 2020

For building in subsided areas of abandoned coal mines and open pits on soils damaged by anthropogenic impact and mining operations, it is proposed to base buildings and structures on a three-layer slab founda- tion including: a solid reinforced concrete foundation slab, a sub-ballast of ground overburden burnt rocks and a rock concrete compensation slab lo- cated between them. During subsidence of damaged soils, the rock concrete compensation slab, collapsing and increasing in volume, fills the sinkhole lens under the building with pieces of rock concrete, protecting the rein- forced concrete foundation slab from destruction. It was experimentally es- tablished that for the production of rock concrete compensation slabs, ce- ment rock concrete with aggregate of ground burnt rocks with a coarse frac- tion (–20+10) mm and a fine fraction (−0.63) mm should be used; the ratio of the percentage mass fraction of coarse and fine fractions being 25/75 and 50/50 and the cement-water mass ratio C:W being 1:0.5. The reinforced concrete compensation slabs of the recommended composition can take a design load of up to 9-11 MPa in dry and up to 8-9 MPa in water-saturated conditions. The use of ground overburden burnt rocks for the manufacture of rock concrete compensation slabs and sub-ballast will allow utilizing overburden burnt dumps and improving the environmental situation when building in subsided areas of abandoned mining enterprises.

Adjustment of the Exploration Grids and its use to increase the Reliability of Geological Models of Coal Deposits
Authors: Rogova Tamara , Shaklein Sergey
Published: June 2020

The current procedure for determining the boundaries of geological domains, the allocation of which is the mandatory element of digital geological modelling, does not entirely take into account the specifics of coal deposits. Without its improvement, it is impossible to increase the reliability of geological models used in the implementation of the “Industry 4.0ˮ strategy. A new method for analysis of geological data is supposed – the adjustment of the exploration grids method. It is to determine the corrections for values of measured parameters, the use of which eliminates the uncertainty of geological data interpretation. The correction values determined by the method of conditional measurements, which used at equalization geodetic networks. Corrections are considered as an indicator of the significance of measurement and interpolation errors which occurs in the vicinity of specific measurement points. The measured values of parameters are not corrected. Geological domains are the areas with close in values corrections, whose boundaries are corrections isolines. Separate single corrections of anomalous magnitude indicate the presence of extreme values parameters.
Preliminary results of tests on nitrogen cushion for combating fire hazard in longwalls rich in methane
Authors: Szurgacz Dawid , Sobik Leszek , Brodny Jarosław , Grigashkin Maxim
Published: June 2020

Ventilation hazard is the most dangerous phenomena occurring in the hard coal extraction process. This particularly applies to endogenous fire hazard. In order to reduce it, it is necessary to improve the effectiveness of preventive measures. Hence this paper presents new solutions that substantially improve fire prevention effectiveness. The main idea is to develop and create an additional nitrogen cushion in the zone behind the powered roof support operating in a longwall face. The solution is based on installations for inerting of goafs and sections of the powered roof support. The nitrogen cushion restricts the access of air and oxygen to the area of goafs and limits the possibility of fire. Practical application of the developed solution allowed for effective reduction of fire hazard in conditions of a very high tendency of coal to self-ignite at short incubation period. This, in turn, enables safe exploitation and decommissioning of the longwall. Undoubtedly, the solution presented and the results obtained constitute a new approach to preventive actions in mines. It is the result of the work of theoretical and practical researchers. The solution is a combination of the potential of these two environments. The developed solution should find wide range of applications in the areas where endogenous fire and methane hazards occur.

Authors: Zakonnova Ludmila , Nikishkin Igor , Stemplewska Ludmila , Chupryakova Alena
Published: June 2020

This paper presents the principles developed by the authors for the operation of reservoirs of technogenic origin, formed as a result of the activities of coal mining and energy enterprises, which can become basic when developing models for the rational use of wastewater and land from coal mining regions: maximum environmental friendliness, reasonable technological (biotechnological) restrictions, forecasting and regulation ecological consequences of the introduction of alien objects of ichthyofauna, etc. The expediency of soft biological methods for cleaning eutrophic water bodies is substantiated. As part of the implementation of the principle of forecasting and regulating the environmental consequences of the introduction of alien fauna ichthyofauna, a new approach is proposed to create a model of variability of the hydroecosystem that will allow developing mechanisms to maintain ecological balance in water bodies and coordinate the work of hatcheries and fishing enterprises, environmental monitoring services and other institutions. The principles of a reasonable biotechnological restriction in the operation of a reservoir and the possibility of alternative use of a reservoir have found their application in the development of warm-water aquaculture using waste warm water. It is proved that the principles of operation of reservoirs of technogenic origin, formed as a result of the activities of coal mining and energy enterprises, may well be successfully implemented to preserve biological diversity in large technogenic reservoirs.

Spatial and Technological Periphery of Types of Economic Activity and Regions in Transition to Sustainable Development
Authors: Kukushkin Sergey , Kalenov Oleg , Kamanina Raisa , Kosareva Olga
Published: June 2020

Currently, the economic development of an industry or type of activity cannot be considered in isolation from the spatial component. Any organization is located in some territory. It has to interact not only with suppliers and consumers, but also with the population that lives in this territory. Therefore, the economic efficiency of the activities of any organization is directly related to the social-and-economic situation of a particular space, territory. The regions in which mining enterprises are located and systemically important are no exception. These organizations belong to the “technological periphery”. New technological solutions, which are the core of economic development for new industries and some of the traditional industries, come here with a delay. Moreover, for many of their consumers, their products are not in demand. And the consequence of this is not only the economic problems of the enterprise, but also the social problems of the region or settlement. The article considers the problem of functioning for these enterprises and regions in the conditions of a new technological structure.
Prospects for Industrial and Post-Industrial Tourism in Kuzbass Coal Mining Cluster
Authors: Rabkina Nadezda , Pavlova Oxana , Valko Olga
Published: June 2020

This article explores Kuzbass potential for industrial and post- industrial tourism, drawing on successful foreign experience and several Russian cases. We identified common international trends in using industrial heritage and outlined the challenges that Russian companies are facing on the way towards a post-industrial paradigm. Western industrial museums present their local industry in the global context, while showing its impact on local community and culture. They make a wide use of modern technology, establish links with science and business, support local arts, and involve authentic members of the industry. Russia, however, can boast very few examples of industrial tourism (e.g. the Krasnaya Gorka Museum in Kemerovo), which is largely seen as having a purely academic appeal. Yet, Kuzbass, with its long history of coal-mining and other industries, has very extensive prospects in this type of tourism. To prove it, we performed a SWOT analysis of a prospective tour into reclaimed lands which showed far more strengths and opportunities for integrating local community, business, and industrial heritage than weaknesses and threats.
The information Resource as a Basis for Digital Reorganization of Career Guidance System and Prospective Recruitment of Personnel for Enterprises of the Mineral Resource Cluster
Authors: Panina Тatjana , Dochkin Sergej
Published: June 2020

The article presents proposals for the organization of targeted selection of personnel for their subsequent training for enterprises of the mineral resource cluster of the region. Special emphasis is placed on training future specialists who are potentially positioned to solve engineering problems and master mining technologies in the context of digital transformation of the economy. The relevance is confirmed by the processes of digitalization of the economy, active use of social networks and network services by young people, which requires changes in conceptual certainty and correction of the validity of professional self- determination and professional orientation. The main task is to develop technological mechanisms for the implementation of professional self- determination and professional orientation of young people in the conditions of digital modernization of the economy. A new model of complex professional orientation and professional self-determination of young people in the educational territorial ecosystem created on the basis of professional connections, acting on the basis of the results of data analysis obtained during the processing of digital user profiles, is proposed. Expected results are the following: the concept of expanding a multi-level intelligent IT platform for a geographically distributed model of professional orientation and professional self-determination of young people; principles of modeling psychological, physiological and cognitive features of a social network user (potential University applicants) based on their digital footprint for solving problems of individualization of the learning process; algorithm for working with the data obtained to form an individual trajectory of personal development. Such approaches will allow changing the idea of professional self-determination as a temporary process at a certain stage of personal development, prolonging activities for the formation and change of career for the entire professional activity of the individual, and ensure the reproduction of highly qualified personnel for the mining industry in the region.

Published: June 2020

The achievement of high production and economic results in the economic entities of the mining industry in Bulgaria is possible only through the elaboration of an effective system for management of the subordinate personnel. In the context of the systematic approach, it is of paramount importance to outline the factors for subordinate staff management which have a positive impact on the economic status of the business organizations. Building a model of factors for subordinate staff management enables us to identify and implement multiple approaches and mechanisms. This creates opportunities for improving the management of the subordinate personnel, which has a positive impact on the development of the mining companies. The purpose of this article is to study the factors for subordinate staff management and to elaborate a model of those which have a direct and indirect impact on the production and economic results of the companies in the quarrying industry in Bulgaria. The article is structured in two main sections. The first includes an analysis of the factors of management of the subordinate workforce, examining the connections and relations with the economic performance of the companies. The second section introduces a model of management factors which prove to be particularly relevant to achieving high economic performance in the Bulgarian mining companies.
Sustainable Development Management: Actors and Institutions in the Post-Industrial Era
Authors: Kazitskaya Nina , Prusova Vera , Bochkov Sergey
Published: June 2020

Sustainable Development is a hypothetical development of a society in which human conditions improve and environmental impact is constrained by the regenerative abilities of the biosphere, so that the natural basis of human life is not destroyed. Sustainable development assumes that meeting the needs of present and future generations is maintained in a safe state, and that environmental conservation is an integral part of the development process. The era of post-industrialization is radically changing the nature of human exposure to the environment. Before raising the question about the current state of natural resource complexes, it should be recognized that humanity still faces the problem of geoecology at the national level, as part of the industrial policy of each country separately. In the post-industrial world, in which the goods created in one country are consumed all over the world, geoecological problems go global, where any component of the environment – natural, technological, social - are combined in a single chain of production and consumption. All of the above requires the formation of an effective system for managing sustainable development in the transition from an industrial to a post-industrial economy, with its specific subjects, goals and subsystems.
The role of energy security in the element base of the industrial region innovative development
Authors: Kopein Valeri , Kopein Andrey , Kostina Tatjana , Filimonova Elena
Published: June 2020

The article examines the peculiarities of the relationship between energy security and innovation processes in the industrial region. Systemized approaches to the methodology for calculating the level of financial security have been consolidated. It is concluded that it is appropriate to use an indicative method of energy security analysis as a classic epistemological variant of the study of the energy security phenomenon. As a result of the assessment of the energy security level of the Kemerovo (Kuzbass) region it is concluded that all indicators of energy security except a certain degree of depreciation of the fixed assets of the fuel and energy complex enterprises have acceptable pre-crisis values. According to the share of own sources in the balance of electricity, the disposable capacity of power plants and the capacity of the largest power plant in Kuzbass region is in the pre-crisis zone, which determines its energy independence. It is noted that the share of coal as the dominant fuel resource in the structure of fuel consumption is at the pre-crisis level. The energy supply is emphasized to cover not only the issues of production, supply of energy resources and availability of energy sources, but also the aspects of the ecology and energy resources accounting. This determines the necessity to adjust the methodology for determining the energy security. It is proposed to supplement the methodology of assessing the level of energy security with indicators that take into account the diversification of sources of electricity generation both as a main resource and the possibility of commercial accounting of electricity consumption. The statement about the impact of the innovation level of energy on the level of region energy security and the pace of innovation process is justified.

Published: June 2020

The article deals with the problem of interrelation of existing ideological paradigms with the enforcement of environmental standards in industrially developed coal regions. It is emphasized that the tasks of ideology as a reflection of industrial, technological, social and other processes include setting goals, defining standards and rules for the functioning of social institutions, it gives meaning to the actions of individuals, forms the daily consciousness of people, generates large-scale political movements. As a product of the development of society, ideology prescribes a model of development and appropriate design of all social institutions, strengthening control over social practices, including the sphere of management of industrialized regions. Attention is focused on the need for changes in the axiological structure of public consciousness based. Much attention is also paid to the significance of globalization, the development of biotechnologies, and the principles of bioethics, which are considered today as moral and ethical standards for modern scientific and technological progress. The innovative ideology of socio-economic development of modern society should be transformed and focused on the principle of environmentalism, reducing the use of non-renewable resources, diversification, and limiting the use of dangerous technologies. At the same time, special importance should be given to the priority position of the environmental imperative in the legal and normative regulation of industrial production and military technologies. And it is precisely the spread of ideological consciousness as a condition for political choice that, in this situation, becomes a necessary component for the exercise of power and the formation of a new practice of social management in industrialized regions.

Anliegen und Methodik Beschreibung der Basisdaten, der häufigsten Symptome und deren medikamentöser, nichtmedikamentöser und kombinierter symptomatischer Behandlung in einer großen Stichprobe von MS-Patienten, die sich in ambulanter Behandlung der Mitgliedspraxen des NeuroTransData (NTD)-Arztnetzwerkes in Behandlung befinden.

Ergebnisse Aktuell sind 21407 Patienten im Register. Das Durchschnittsalter betrug 49,0 ± 13,0 Jahre, der Frauenanteil lag bei 72,3 %, die Krankheitsdauer bei 14,3 ± 8,9 Jahren. Eine schubförmig-remittierende MS (RRMS) lag in 77 % vor, 15 % sekundär-progrediente MS, primär-progrediente MS (PPMS) 5 %. Der durchschnittliche EDSS-Score der Gesamtstichprobe lag bei 2,8 (Range 0,5–8). Fatigue war in allen Subtypen das häufigste Symptom (96 %), gefolgt von der Spastik (31 %), v.a. bei der SPMS (47 %) und PPMS (36 %). Hinsichtlich der medikamentösen, nichtmedikamentösen und kombinierten symptomatischen Behandlung zeigte sich eine große Variationsbreite. Während in der Gesamtpopulation die Spastik in 81 % behandelt wurde, erhalten nur 21 % der Patienten eine Behandlung der Fatigue. Auch Defäkations- und Miktionsstörungen waren in unserer Stichprobe häufig noch unbehandelt (69 % bzw. 56 %).

Schlussfolgerungen Aufbau, kontinuierliche Weiterentwicklung und Pflege eines Registers stellen bei komplexen und chronischen Erkrankungen wie der MS ein wichtiges Instrument zur Beurteilung und damit auch zur Verbesserung und zum Vergleich der Behandlungsart und ihrer Defizite dar.

Unsere Ergebnisse sind methodisch schwer vergleichbar mit der Stichprobe des MS-Registers der DMSG. Die Fatigue war aber in beiden Registern das häufigste Symptom.
Die Charcot Neuroarthropathie des Kniegelenkes
Authors: Illgner Ulrich
Published: June 2020

Hintergrund Während die Charcot Neuroarthropathie (CN) des
Fußes immer mehr Aufmerksamkeit gewinnt, wird die CN des Knies kaum
beachtet. Zwar erschienen in den letzten Jahren einige Publikationen zu CN
des Knies, es handelte sich aber fast ausschließlich um
Einzelfallbeschreibungen und meist dann auch nur zur endoprothetischen
Versorgung. Es existieren nur 2 systematische Beschreibungen der
Erkrankung.

Ergebnisse Es wird an Hand eines Patienten nun der Krankheitsverlauf
und die Charakteristika der CN am Knie detailiert sowie die Therapieoptionen
dargestellt und in den Kontext einer vorangegangenen Publikation mit 3
Patienten mit CN des Kniegelenkes gesetzt. Die CN des Kniegelenkes zeigte
die gleiche schubartige und stadienhafte Klinik analog zur CN des
Fußes. Die Anwendung derselben Therapieprinzipien wie bei der CN des
Fußes (sofortige Immobilisierung und Offloading) führte in
allen Fällen zu einer schnellen Überführung in ein
inaktives Stadium mit Konsolidierung des Befundes, sodass alle Patienten
mittels Orthesen und ohne Operation wieder gehfähig wurden. Es
handelte sich bei allen Patienten um Diabetiker mit multiplen Komplikationen
(3x Diabetes Typ I, 1x Diabetes Typ 2), alle litten an einer stark
fortgeschrittenen Polyneuropathie der unteren Extremität.

Schlußfolgerung Die CN des Kniegelenkes stellt eine schwere
Komplikation bei Polyneuropathie dar und darf nicht übersehen
werden. Dieselben Diagnose- und Behandlungskriterien wie bei der CN des
Fußes führten zum Erhalt von Knie und
Gehfähigkeit.
Unterlassene Notfallbehandlung eines akuten allergischen Kontaktekzems
Authors: Elsner P. , Meyer J.

Bei einer Patientin traten nach der Färbung der Augenbrauen mit einem vermutlich Paraphenylendiamin-haltigen Produkt eine großflächige Gesichtsrötung und eine periorbitale Schwellung auf. Bei der Vorstellung in der interdisziplinären Notaufnahme eines nahegelegenen Klinikums wurde auf eine Therapie verzichtet und die Patientin an einen niedergelassenen Dermatologen verwiesen. Erst mit Verzögerung und nach weiterer Verschlechterung des Hautbefundes wurde in einem anderen von der Patientin konsultierten Klinikum eine allergologische Notfalltherapie mit einem systemischen Glukokortikosteroid und einem Antihistaminikum eingeleitet.

Die Schlichtungsstelle beurteilte die Unterlassung der Notfalltherapie als einen ärztlichen Behandlungsfehler. Bei Einbezug der Kenntnis der zeitlichen Entwicklung der Erkrankung durch eine allergische Verursachung, die dem Dienstarzt bekannt war, wäre bei Einsatz einer Kortikoidtherapie das Krankheitsgeschehen wesentlich zu beeinflussen und eine deutliche Verkürzung des Krankheitsverlaufs zu erwarten gewesen.

Klinisch schwere akute allergische Kontaktekzeme bedürfen einer medizinischen Notfalltherapie, wozu neben einer Entfernung und Meidung möglicherweise auslösender Allergene auch eine topische und ggf. systemische antiinflammatorische Therapie gehört. Die Unterlassung dieser Notfalltherapie kann eine ärztliche Sorgfaltspflichtverletzung und damit einen Behandlungsfehler darstellen. Die Versorgung dermatologischer Notfälle durch Nichtdermatologen entbindet diese nicht von der Pflicht zu einer Notfallbehandlung, wie sie unabhängig von der Spezialisierung von jedem Arzt erwartet werden muss. Interdisziplinäre Notfallambulanzen sollten Möglichkeiten der konsiliarischen Unterstützung durch Dermatologen vorsehen.

Hintergrund Bei 15 – 20% der Patienten mit akuter Pankreatitis entwickelt sich eine nekrotisierende Form. Die Mortalität beträgt bis zu 20%. Entscheidende Säulen der Behandlung sind die intensivmedizinische Therapie sowie chirurgische und interventionelle Maßnahmen.

Methoden Diese Übersichtsarbeit zur Indikationsstellung von chirurgischen und interventionellen Maßnahmen bei der nekrotisierenden Pankreatitis wurde auf der Basis einer systematischen Literaturrecherche verfasst. In der Analyse wurden 85 Artikel ausgewertet. Die Ergebnisse wurden im Delphi-Befragungsverfahren der Qualitätskommission der Deutschen Gesellschaft für Allgemein- und Viszeralchirurgie (DGAV) und Experten auf einer Sitzung des Viszeralmedizin-Kongresses in Wiesbaden 2019 vorgestellt. Bei der abschließenden Formulierung der Empfehlungen wurde ein starker Konsensus von 84% bei den Befragten erreicht.

Ergebnisse Bei Nachweis oder Verdacht auf eine Infektion der Pankreasnekrosen besteht eine Indikation zur chirurgischen und interventionellen Behandlung (Empfehlungsgrad: stark; Evidenzstärke: schwach). In Ausnahmefällen stellen auch sterile Nekrosen eine Indikation zur Intervention dar. Wenn es der klinische Zustand erlaubt, sollte die Intervention bis in die 4. Krankheitswoche geschoben werden. Als Therapiestrategie wird mit hohem Evidenz- und Empfehlungsgrad der „step-up approach“ empfohlen. Diese Strategie der Therapieeskalation beinhaltet als 1. Maßnahme eine Drainagebehandlung und bei Erfolglosigkeit die minimalinvasive chirurgische oder endoskopische Nekrosektomie. Sind die minimalinvasiven Techniken nicht effektiv, ist die offene Nekrosektomie indiziert. Nach primärer Drainagebehandlung kann bei 35 – 50% der Patienten die 2. Therapiestufe der Nekrosektomie vermieden werden. Indikationen zur Notfalloperation sind Organperforation, Darmischämie, interventionell nicht stillbare Blutungen und das abdominelle Kompartmentsyndrom bei erfolgloser konservativer Therapie. Spätabszesse und symptomatische Pseudozysten sind Indikationen für eine interventionelle Drainagebehandlung. Bei der biliären Pankreatitis ist die Cholezystektomie indiziert, bei der milden Form frühelektiv und bei schwerem Verlauf frühestens nach 6 – 8 Wochen.

Schlussfolgerung Die vorliegenden Empfehlungen enthalten Kriterien für die Indikationsstellung zur chirurgischen und interventionellen Behandlung der akuten Pankreatitis. Sie sollen als Referenzstandards für die Entscheidungsfindung in einem multidisziplinären Team dienen.
