‘AUSSERORDENTLICH BEWEGLICH UND NICHT ZU FANGEN’: ELUSIVENESS IN KAFKA
Authors: Speirs Ronald 
Published: June 2017

ABSTRACTThis paper takes as its starting point the interpretive puzzles presented to the reader by the highly mobile and elusive phenomenon ‘Odradek’ in Kafka's ‘Die Sorge des Hausvaters’. It goes on to consider, on the one hand, Kafka's efforts in his aphorisms to build a metaphysical scheme centred on movement as a key feature of human existence, and, on the other hand, various elements in Kafka's writing which elude containment within that metaphysical construct.Dieser kurze Beitrag beginnt mit einer Betrachtung der rätselhaften, äußerst beweglichen und nicht zu fangenden Figur Odradek in der Erzählung ‘Die Sorge des Hausvaters’. Davon ausgehend untersucht der Artikel auf der einen Seite Kafkas Bemühungen, eine metaphysische Interpretation des menschlichen Lebens aufzubauen, bei der die Bewegung eine Schlüsselrolle spielt; auf der anderen Seite richtet er die Aufmerksamkeit auf eine Reihe von Stellen bei Kafka, die sich weigern, in jenem metaphysischen Bau einfangen zu lassen.

AbstractIntroductionLong‐term persistent Helicobacter pylori infection has been associated with ulceropeptic disease and gastric cancer. Although H. pylori is predominantly acquired early in life, a clear understanding of infection dynamics during childhood has been obfuscated by the diversity of populations evaluated, study designs, and methods used.AimUpdate understanding of true prevalence of H. pylori infection during childhood, based on a critical analysis of the literature published in the past 5 years.MethodsComprehensive review and meta‐analysis of original studies published from 2011 to 2016.ResultsA MEDLINE®/PubMed® search on May 1, 2016, using the terms pylori and children, and subsequent exclusion, based on abstract review using predefined criteria, resulted in 261 citations. An Embase® search with the same criteria added an additional 8 citations. In healthy children, meta‐analysis estimated an overall seroprevalence rate of 33% (95% CI: 27%‐38%). Seven healthy cohort studies using noninvasive direct detection methods showed infection prevalence estimates ranging from 20% to 50% in children ≤5 and 38% to 79% in children >5 years. The probability of infection persistence after a first positive sample ranged from 49% to 95%. Model estimates of cross‐sectional direct detection studies in asymptomatic children indicated a prevalence of 37% (95% CI: 30%‐44%). Seroprevalence, but not direct detection rates increased with age; both decreased with increasing income. The model estimate based on cross‐sectional studies in symptomatic children was 39% (95% CI: 35%‐43%).ConclusionsThe prevalence of H. pylori infection varied widely in the studies included here; nevertheless, model estimates by detection type were similar, suggesting that overall, one‐third of children worldwide are or have been infected. The few cohort and longitudinal studies available show variability, but most studies, show infection rates over 30%. Rather surprisingly, overall infection prevalence in symptomatic children was only slightly higher, around 40%. Studies including only one positive stool sample should be interpreted with caution as spontaneous clearance can occur.

AimsSurgical excision of all benign vascular lesions of the breast identified by core needle biopsy has been recommended in the past to rule out a more serious lesion. In this study we investigated the clinical, radiological and pathological findings in patients diagnosed with a benign vascular lesion at our institution to assess whether excision may be spared for lesions without atypia.Methods and resultsWe searched the electronic medical record for patients with a vascular lesion of the breast diagnosed between 2000 and 2015. The study population consisted of 84 patients, 83 females and one male. The index diagnoses included 76 benign vascular lesions, five vascular lesions with cytological atypia and three angiosarcomas. A radiologist reviewed all pre‐ and post‐biopsy imaging studies; all cases had concordant radiological and pathological findings. Based on radiological and histological correlation, the vascular lesion accounted for the radiological target in 40 (48%) cases and was deemed an incidental finding in 44 (52%). Seven of 32 (22%) targeted and 10 of 44 (23%) incidental benign vascular lesions underwent surgical excision; there were no upgrades at excision. No recurrences or clinical events were observed in patients with a targeted or incidental benign vascular lesion with a median follow‐up of 39 months and 40.6 months, respectively.ConclusionOur data suggest that benign vascular lesions diagnosed on core biopsy with concordant radiological and pathological findings do not warrant surgical excision.

AbstractThe study presents the results of the study on porous composite biomaterials obtained using lyophilization method based on polymer solutions: chitosan solution, sodium alginate solution, or polylactide solution, and ZnO‐doped bioglass from CaO‐SiO2‐P2O5 system. The properties of zinc ions were used, which have bactericidal, immune‐stimulating, and tissue‐regenerating functions in the organism. The effects of the polymer type, granulation, and bioglass amount, as well as the amount of solvent on composite microstructure, were studied. SEM‐EDS technique was used to visualize and describe the surface results occurring after incubation of composite in the Simulated Body Fluid (SBF). The selected method of preparation, used substrates, and the process conditions resulted in porous composites of the open, connected pore structure. It was proved that composite microstructure may be controlled by the appropriately selected amount of bioglass in relation to the polymer and its appropriate grain sizes. The morphology of the obtained composites is also affected by the amount of the solvent in lyophilizated dispersions. It was proved that bioactivity in composite material is induced by bioglass because after SBF incubation the surface layer is enriched with Ca and P, what may lead to a gradual formation of apatite layer. The obtained results enabled selection of the composites for further in vitro studies concerning cytotoxicity and antibacterial activity.
Recomposition and levelling of consumption expenditures across four economic shocks in Russia, 1994–2014
Authors: Kotelnikova Zoya , Radaev Vadim 
Published: June 2017

AbstractThe authors examine the changes in the level and composition of consumption expenditures and their associations with household per capita incomes across the four different economic shocks that Russia has experienced since 1994. Data were collected from a nationally representative annual panel survey of households between 1994 and 2014, supplemented by the Federal State Statistics Service source. Four hypotheses on the relationship between per capita income and consumption, the composition of cutbacks, a levelling of expenditures among income groups, and the stability of the pattern of consumer response to economic shocks are proposed. The data demonstrate that consumption expenditures on food, non‐food, and services decreased together with per capita income during the four economic shocks. Only a few examples of significant smoothing effects were found. All income groups recomposed their expenditures to maintain consumption of necessities. The high‐income group reduced a higher proportion of expenditures on food and services, implying that economic shocks produce a temporary levelling effect on the living standards of different income groups. A relatively stable pattern of consumer responses to economic shocks was revealed, despite these shocks’ divergence; this pattern implies a temporary economization and simplification of expenditures with a fast return to pre‐crisis spending once the crisis is over.
Coping with crises: Consumption and social resilience on markets
Authors: Koos Sebastian , Vihalemm Triin , Keller Margit 
Published: June 2017

AbstractCrises, especially economic crises are an immanent element of modern market societies. While some research has been devoted to understanding the consequences of such crises on consumption, a systematic integrative approach to this problem is still missing. In this editorial we develop an encompassing model for the study of crises and consumption, to identify and connect the different elements important for understanding and explaining the relationship. Thereafter we present the papers of this special issue and discuss their contributions, based on the proposed framework. Suggestions for future research conclude the editorial.
Consumers’ evaluations of the efficiency of actions to improve environmental quality: A comparative study between Brazil and China
Authors: Mainardes Emerson Wagner , Yeh Tatiana , Leal Aureo 
Published: June 2017

AbstractThere is a gap in our knowledge about environmentally conscious consumers in industrialized economies and the desire to achieve sustainable economies. Given that most aspects of consumer behaviour are culture bound, this paper contributes by comparing consumers’ evaluations of the efficiency of actions to improve environmental quality in two of the most promising industrializing consumer societies: Brazil and China. The proposed conceptual framework includes environmental concerns, perceived consumer effectiveness, green attitudes, green behaviours and external motivators as constructs to explain the perception of efficient environmental support. Field research was conducted in Brazil with 1,149 respondents, and in China with 632 respondents to test the model. The results suggested that the belief that environmental quality can be improved is directly associated with consumers’ internal and external motivators. However, cultural traits drove important differences in the evaluation of the efficiency of such improvements. Specifically, Chinese people tended to rely on collective leadership to create the conditions necessary for improving environmental quality, while they remained concerned with the current status. In contrast, Brazilians accepted more personal responsibility for the results, although they face important constraints, such as the availability of products.
Maternal coping with the prospect of liver transplant among their school‐age children

AbstractThe purpose of the current study was to describe the following: maternal coping with the prospect of becoming the living‐donor liver transplant for their child; the daily lives of school‐age children surviving biliary atresia with their native liver; and to explore the relationship between these individuals. Semistructured interviews were conducted with 6 school‐age children surviving biliary atresia with their native liver and their mothers. The interviews were conducted from June to August 2014, and a qualitative content analysis was used. Results showed that mothers realized a possible need for transplantation in the future, which contributes to emotional and practical uncertainties. The mothers coexisted with this uncertainty and preferred to use a buffering strategy. In contrast, the children did not consider their illness and future and did not adhere to a therapeutic regimen. It is suggested that living with uncertainty about the health and survival of their children is advantageous for mothers. However, problems related to the psychosocial aspect and child's adherence may occur in the future. In addition, problem‐solving coping strategies for mothers and the independence of chronically ill children with liver disease should be promoted.

AbstractAimTo assess the scientific evidence about the types of support surfaces used in intraoperative surgical practice in the prevention of pressure ulcers due to surgical positioning.MethodThis is an integrative literature review. The electronic databases Cochrane, PubMed, Web of Science, Scopus, Lilacs, and CINAHL were used. The descriptors surgical patients, support surfaces, perioperative care, patient positioning, and pressure ulcer were used in the search strategy. Articles that addressed the use of support surfaces intraoperatively, published between 1990 and 2016, were selected. The PRISMA guidelines were used to structure the review.ResultsOf 18 evaluated studies, most were in English, followed by Portuguese and Spanish; most were performed by nurses. The most commonly cited support surfaces were viscoelastic polymer, micropulse mattresses, gel based mattresses, and foam devices.ConclusionThere are gaps in knowledge regarding the most efficient support surfaces and the specifications of the products used to prevent pressure ulcers due to surgical positioning.

OPTIMAL R&D FOR NONRENEWABLE RESOURCES: THE CASE OF COST REDUCING TECHNOLOGY
Authors: Norquist Suzanne M. 
Published: June 2017

A model is developed to determine optimal R&D spending and completion time when R&D results in lower extraction costs of a nonrenewable resource deposit. Examples of R&D projects for which the model is designed are in‐situ leaching for mining and carbon dioxide injection in petroleum.The model is a combined R&D/nonrenewable resource model (CM). Results from the CM are compared to simulations of an R&D model which ignores the nonrenewable resource. The comparison demonstrates the importance of including resource parameters in the R&D spending model.The CM extends the literature by considering R&D spending and exhaustible natural resource production simultaneously. It demonstrates the importance of including the resource deposit when R&D affects the deposit. This is important because more accurate models of R&D will increase the profitability of the R&D projects.
Unravelling direct and indirect effects of hierarchical factors driving microbial stream communities
Authors: Pajunen Virpi , Luoto Miska , Soininen Janne 
Published: June 2017

AbstractAimThe diversity and distributions of organisms are jointly influenced by local environment and large‐scale variables, such as land cover patterns, dispersal processes and climate. However, the drivers of microbial diversity are complex and the pathways of these drivers’ effects are to date largely unresolved, especially in freshwaters. We disentangled the causal direct and indirect effects of climate, land cover and water chemistry on stream diatom communities using hierarchical settings.LocationFinland, a geographical gradient of c. 1200 km (60°–70°N).MethodsWe used structural equation modelling (SEM) to analyse patterns in diatom richness, composition and the uniqueness of species composition in 143 streams. The community composition was defined as the value of the first axis in non‐metric multidimensional scaling and the uniqueness of species composition of each site as its local contribution to beta diversity.ResultsSpecies richness was mainly affected directly by energy and resource availability, increasing with nutrients but decreasing with growing degree days (GDD). The community composition was strongly influenced directly by conductivity and mainly indirectly by anthropogenic land use but also to a lesser degree by GDD (directly and indirectly), indirectly by precipitation and directly by the amount of boreal wetlands. The uniqueness of species composition increased with conductivity but decreased with nutrient concentrations with high number of unique species in southernmost and northernmost sites.Main conclusionsOur SEM analyses revealed some of the important links between climate, land cover and water chemistry, all of which influenced the microbial diversity. Energy availability has varying indirect and direct effects on diatom communities regardless of local stream conditions, whereas land cover patterns affect aquatic communities most likely indirectly through water chemistry. Collectively, these results suggest that it is important to consider environmental variables simultaneously at different hierarchically ordered scales in macroecological and biogeographical research.
Knockdown of Mtfp1 can minimize doxorubicin cardiotoxicity by inhibiting Dnm1l‐mediated mitochondrial fission
Authors: Aung Lynn H. H. , Li Ruibei , Prabhakar Bellur S. , Li Peifeng 
Published: June 2017

AbstractThe long‐term usage of doxorubicin (DOX) is largely limited due to the development of severe cardiomyopathy. Many studies indicate that DOX‐induced cardiac injury is related to reactive oxygen species generation and ultimate activation of apoptosis. The role of novel mitochondrial fission protein 1 (Mtfp1) in DOX‐induced cardiotoxicity remains elusive. Here, we report the pro‐mitochondrial fission and pro‐apoptotic roles of Mtfp1 in DOX‐induced cardiotoxicity. DOX up‐regulates the Mtfp1 expression in HL‐1 cardiac myocytes. Knockdown of Mtfp1 prevents cardiac myocyte from undergoing mitochondrial fission, and subsequently reduces the DOX‐induced apoptosis by preventing dynamin 1‐like (Dnm1l) accumulation in mitochondria. In contrast, when Mtfp1 is overexpressed, a suboptimal dose of DOX can induce a significant percentage of cells to undergo mitochondrial fission and apoptosis. These data suggest that knocking down of Mtfp1 can minimize the cardiomyocytes loss in DOX‐induced cardiotoxicity. Thus, the regulation of Mtfp1 expression could be a novel therapeutic approach in chemotherapy‐induced cardiotoxicity.

Published: June 2017

AbstractObjectivesThis study aimed to evaluate the safety of ridge preservation/augmentation procedures when performed at compromised extraction sockets.MethodsPatients subject to ridge preservation/augmentation at periodontally compromised sockets at Seoul National University Dental Hospital (SNUDH) were evaluated in a chart review. Tooth extractions due to acute infection were not included in our study as chronically formed lesions are the only lesions that can be detected from radiographic images. If inflammatory symptoms persisted following ridge preservation/augmentation and antimicrobial and anti‐inflammatory therapy, the patient was categorized as a re‐infection case and implanted biomaterial removed.ResultsOf 10,060 patients subject to tooth extractions at SNUDH, 2011 through 2015, 297 cases meeting inclusion criteria were reviewed. The severity and type of lesions were not specific because extracting data was only done by radiographic images and chart records. The review identified eight patients exhibiting inflammatory symptoms that required additional antimicrobial and anti‐inflammatory therapy. Within this group, re‐infection occurred in two patients requiring biomaterials removal. The final safety rate for the ridge preservation/augmentation was 99.3%. None of the demographic factors, systemic conditions or choice of biomaterial affected the safety of ridge preservation/augmentation.ConclusionAlveolar ridge preservation/augmentation at periodontally compromised sockets appears safe following thorough removal of infectious source.

Published: June 2017

AbstractAimAssess the association of flossing with periodontitis.Materials and MethodsThis was a cross‐sectional study using the National Health and Nutrition Examination Survey (NHANES) years 2011‐2014. We used three categories of flossing: 0–1, 2–4 and ≥5 days in the past week and the CDC definition of periodontitis. We calculated odds ratios controlling for age, gender, smoking, drinking, income and dentist visits.ResultsA total of 6939 adult subjects were included, 35% flossed ≤1 time a week, and 40% had periodontitis. After adjustment, the odds of periodontitis were 17% lower for subjects who flossed >1 time a week than for subjects who flossed less often (odds ratio=0.83, 95% CI 0.72–0.97). A dose response was not observed. Men were twice as likely as women to have periodontitis. Younger subjects, non‐smokers and subjects with the highest incomes had lower odds of having periodontitis.ConclusionsFlossing was associated with a modestly lower prevalence of periodontitis. Older age, being male, smoking, low income and less frequent dental visits were associated with a higher prevalence of periodontitis. Flossing 2–4 days a week could be as beneficial as flossing more frequently. This is a cross‐sectional study so a causal relation between flossing and periodontitis cannot be established.

AbstractThe invasiveness of Drosophila suzukii Matsumura is causing sizable damage to soft fruits and cherry. In order to define a targeted strategy for D. suzukii management, it is important to have access to highly sensitive trapping tools for detection, monitoring and control that are also selective, practical in use, economic, and with low environmental impact. The aim of this study was to compare different combinations of traps and lures to define a best practice approach for D. suzukii monitoring in Italy, extended over a wide elevational gradient and landscape complexity. The high attractiveness was not always combined with high selectivity, as in some cases up to 95% of the Drosophila spp. captured were belonging to species different from D. suzukii. The commercial Droso‐Trap was very efficient providing high capture ability. Overall, the most attractive lure was Droskidrink while Suzukii Trap was the most selective one. Lure attractiveness and selectivity, however, changed during the season in relation to environmental temperatures and phenological developmental stages, suggesting the need for implementing different lures in different periods and for the different purposes (monitoring or mass trapping). In terms of trap management, Droskidrink showed the problem of bacterial‐gel formation, while Suzukii Trap and Pherocon SWD were easier to handle as they did not need to be checked at weekly interval. Finally, these results were gathered to convey the most efficient combination of trap and bait able to efficiently perform mass trapping and attract and kill technique.
