Published: May 2016

Background: The intraoperative assessment of the articular surface in displaced intra-articular distal tibia fractures can be challenging using conventional fluoroscopy. The aim of the study was to determine the frequency and the method of intraoperative corrections of fracture reductions or implant placements during open reduction, internal fixation by using cone beam computed tomography (CT) after conventional fluoroscopy. Methods: Displaced intra-articular distal tibia fractures were retrospectively analyzed from August 2001 until December 2011. The fractures were classified according to the standards of the AO/OTA as type B or C and treated with open reduction and internal plate fixation. After primary reduction using conventional fluoroscopy, an additional cone beam CT scan was used to determine the alignment of the joint line and the implant position. The number of intraoperative revisions of the primary reduction due to the use of cone beam CT was analyzed. Results: A total of 143 patients with an intra-articular tibial plafond fracture were included in the analysis. In 43 patients (30%), an intraoperative correction was performed after the cone beam CT scan. In 34 (24%) of these cases, intraoperative correction was required because of inadequate joint line reduction. Nine (6%) corrections were required as a result of a malposition of the implant. The revision rate did not differ by fracture classification. Conclusion: Despite its acceptance as the standard method of imaging, intraoperative conventional fluoroscopy for the assessment of implant positioning and fracture reduction of tibial plafond fractures is limited. The intraoperative utilization of cone beam CT provided additional information for the surgeon to detect insufficient reduction or implant malposition. Level of Evidence: Level III, retrospective comparative series.
Care leavers’ involvement in research: An ethnographic case study on impact
Authors: Liabo Kristin 
Published: May 2016

Introduction Reporting data from a case study of a collaborative systematic review, this paper discusses the impact service user involvement might have on research, and how research might benefit from this. Methods This was a qualitative case study. The researcher analysed process data on the collaboration in the form of meeting transcripts and minutes, reflective interviews and the researchers’ own field diary. The review was also compared with two systematic reviews on a similar topic, using the AMSTAR checklist. Results The young people had influence at all stages of the review, but most importantly shifted its focus from healthcare to education, emphasising education as an important determinant of health. Conclusion Young people involved in this review influenced the researcher’s reviewing as well as the review, which shows that involving service users in research is important in order to reduce researcher bias in social care research.
Can student health professionals accurately estimate alcohol content in commonly occurring drinks?
Authors: Sinclair Julia , Searle Emma 
Published: May 2016

Objectives: Correct identification of alcohol as a contributor to, or comorbidity of, many psychiatric diseases requires health professionals to be competent and confident to take an accurate alcohol history. Being able to estimate (or calculate) the alcohol content in commonly consumed drinks is a prerequisite for quantifying levels of alcohol consumption. The aim of this study was to assess this ability in medical and nursing students. Methods: A cross-sectional survey of 891 medical and nursing students across different years of training was conducted. Students were asked the alcohol content of 10 different alcoholic drinks by seeing a slide of the drink (with picture, volume and percentage of alcohol by volume) for 30 s. Results: Overall, the mean number of correctly estimated drinks (out of the 10 tested) was 2.4, increasing to just over 3 if a 10% margin of error was used. Wine and premium strength beers were underestimated by over 50% of students. Those who drank alcohol themselves, or who were further on in their clinical training, did better on the task, but overall the levels remained low. Conclusions: Knowledge of, or the ability to work out, the alcohol content of commonly consumed drinks is poor, and further research is needed to understand the reasons for this and the impact this may have on the likelihood to undertake screening or initiate treatment.

Published: May 2016

AbstractBackgroundRecent efforts in osteoarthritis (OA) research have highlighted synovial inflammation and involvement of immune cells in disease onset and progression. We sought to establish the in-vivo immune response in collagenase-induced OA and investigate the ability of human mesenchymal stem cells (hMSCs) overexpressing viral interleukin 10 (vIL-10) to modulate immune populations and delay/prevent disease progression.MethodsEight-week-old male C57BL/6 mice were injected with 1 U type VII collagenase over two consecutive days. At day 7, 20,000 hMSCs overexpressing vIL-10 were injected into the affected knee. Control groups comprised of vehicle, 20,000 untransduced or adNull-transduced MSCs or virus alone. Six weeks later knees were harvested for histological analysis and popliteal and inguinal lymph nodes for flow cytometric analysis.ResultsAt this time there was no significant difference in knee OA scores between any of the groups. A trend toward more damage in animals treated with hMSCs was observed. Interestingly there was a significant reduction in the amount of activated CD4 and CD8 T cells in the vIL-10-expressing hMSC group.ConclusionsvIL-10-overexpressing hMSCs can induce long-term reduction in activated T cells in draining lymph nodes of mice with collagenase-induced OA. This could lead to reduced OA severity or disease progression over the long term.
Evidence for an audience effect in mice: male social partners alter the male vocal response to female cues
Authors: Seagraves Kelly M. , Arthur Ben J. , Egnor S. E. Roian 
Published: May 2016

ABSTRACTMice (Mus musculus) form large and dynamic social groups and emit ultrasonic vocalizations in a variety of social contexts. Surprisingly, these vocalizations have been studied almost exclusively in the context of cues from only one social partner, despite the observation that in many social species the presence of additional listeners changes the structure of communication signals. Here, we show that male vocal behavior elicited by female odor is affected by the presence of a male audience – with changes in vocalization count, acoustic structure and syllable complexity. We further show that single sensory cues are not sufficient to elicit this audience effect, indicating that multiple cues may be necessary for an audience to be apparent. Together, these experiments reveal that some features of mouse vocal behavior are only expressed in more complex social situations, and introduce a powerful new assay for measuring detection of the presence of social partners in mice.

Upper extremity nerve block: how can benefit, duration, and safety be improved? An update
Authors: Brattwall Metha , Jildenstål Pether , Warrén Stomberg Margareta , Jakobsson Jan G. 
Published: May 2016

Upper extremity blocks are useful as both sole anaesthesia and/or a supplement to general anaesthesia and they further provide effective postoperative analgesia, reducing the need for opioid analgesics. There is without doubt a renewed interest among anaesthesiologists in the interscalene, supraclavicular, infraclavicular, and axillary plexus blocks with the increasing use of ultrasound guidance. The ultrasound-guided technique visualising the needle tip and solution injected reduces the risk of side effects, accidental intravascular injection, and possibly also trauma to surrounding tissues. The ultrasound technique has also reduced the volume needed in order to gain effective block. Still, single-shot plexus block, although it produces effective anaesthesia, has a limited duration of postoperative analgesia and a number of adjuncts have been tested in order to prolong analgesia duration. The addition of steroids, midazolam, clonidine, dexmedetomidine, and buprenorphine has been studied, all being off-label when administered by perineural injection, and the potential neurotoxicity needs further study. The use of perineural catheters is an effective option to improve and prolong the postoperative analgesic effect. Upper extremity plexus blocks have an obvious place as a sole anaesthetic technique or as a powerful complement to general anaesthesia, reducing the need for analgesics and hypnotics intraoperatively, and provide effective early postoperative pain relief. Continuous perineural infusion is an effective option to prolong the effects and improve postoperative quality.
A ADEQUAÇÃO DA CONCEPÇÃO DE INTITULAMENTOS PARA A APRECIAÇÃO DE DOTAÇÕES E SERVIÇOS AMBIENTAIS

<p>A questão ambiental sempre caracterizou-se como um tema de destaque na literatura econômica, não se restringindo apenas ao direito ambiental, mas integrando o direito econômico, direito comunitário, direito internacional. Diante disso, o hábitat ambiental é o fundamento da vida, razão pela qual mostra imprescindível que os agentes sociais se conscientizem da importância de zelar este bem precioso, para que as futuras gerações possam usufruir de qualidade de vida, visto que se não for contido o esgotamento dos recursos naturais, não haverá equilíbrio vital no planeta. O meio ambiente deve ser tutelado como um direito fundamental do ser humano, visto que consiste em patrimônio da humanidade. Em virtude disso, a natureza não se caracteriza apenas como um recurso produtivo explorado pelos indivíduos detentores do capital e, sim como uma garantia fundamental do ser humano. Diante das diversas interferências humanas no meio ambiente, a teoria econômica passa a preocupar-se com a destruição dos ecossistemas ambientais, dando origem a uma série de alternativas de análise. Neste sentido, entre estas alternativas, destaca-se a abordagem das capacitações elaborada pelo economista indiano Amartya Sen. Em decorrência disso, o empenho analítico visa englobar na análise da realidade social as capacitações. Por conseguinte, uma das percepções gerais que abrangem o sentido analítico é a de intitulamento. Desta maneira, esta pesquisa possui como escopo principal analisar a adequação da concepção de intitulamentos para a apreciação de dotações e serviços ambientais. </p>

The Sensibility of the State: Lookout Mountain Laboratory’s Operation Ivy and the Image of the Cold War “Super”
Authors: O’Gorman Ned , Hamilton Kevin 
Published: May 2016

Abstract
In 1953 a Hollywood-based U.S. Air Force film studio, Lookout Mountain Laboratory, produced a documentary film about America’s first detonation of a thermonuclear device, the 1952 “MIKE” device. The film, called Operation Ivy, was initially shown only to the highest-level government officials, but a later, edited version was eventually released for public distribution. We argue that the story of Operation Ivy illuminates not only the ways in which the rhetoric of the “Super” was managed but also the way in which the Cold War state was both subject to and productive of political and aesthetic sensibilities.
The Rhetoric of Credit, the Rhetoric of Debt: Economic Arguments in Early America and Beyond
Authors: Herring William Rodney 
Published: May 2016

Abstract
In 1790, the new United States faced a tremendous debt. Secretary of the Treasury Alexander Hamilton proposed policies for funding the debt and establishing the nation’s credit. James Madison agreed about the priority of establishing credit, but he opposed Hamilton’s proposals in the House of Representatives. The arguments each man advanced constituted two distinct rhetorics about debt, two ways of conceiving and responding to the new nation’s obligation. This essay analyzes these arguments as well as one strategy common to both men’s work: the use of an analogy insisting that states should behave as individuals do. These arguments were crucial in constructing conditions of stability in the country’s fledgling credit economy. The essay concludes by considering the legacy both of the analogy and of Hamilton’s rhetoric of credit and Madison’s rhetoric of debt in current debates over the United States’ public debt.

Published: May 2016

Abstract
The aim of the study was to analyze and assess the possibility of using a two-stage filtration system with ceramic membranes: a 3-tube module with 1.0 kDa cut-off (1st stage) and a one-tube module with 0.45 kDa cut-off (2nd stage) for treating effluent water from a juvenile African catfish aquaculture. The study revealed that during the 1st filtration stage of the effluent water, the highest degrees of retention were obtained with respect to: suspended solids SS (rejection coefficient RI=100%), turbidity (RI=99.40%), total iron (RI=89.20%), BOD5 (RI=76.0%), nitrite nitrogen (RI=62.30%), and CODCr (RI=41.74%). The 2nd filtration stage resulted in a lower reduction degree of the tested indicators in comparison to the 1st filtration stage. At the 2nd stage, the highest values of the rejection coefficient were noted in for the total iron content (RIV=100%), CODCr (RIV=59.52%; RV=64.28%, RVI=63.49%) and turbidity (RIV and RV = 45.0%, RVI=50.0%). The obtained results indicate that ceramic membranes (with 1.0 and 0.45 kDa cut-offs) may be used in recirculation aquaculture systems as one of the stages of effluent water treatment.
The methods of evaluating storage volume for single-chamber reservoir in urban catchments
Authors: Szeląg Bartosz , Mrowiec Maciej 
Published: May 2016

Abstract
The article presents a method of designing single-chamber rectangular detention reservoirs based on nomographs connecting the parameters and the shape of the inflow with the reservoir hydrograph (triangular, described by the power function and described by the gamma distribution) as well as the hydraulic characteristics of the accumulation chamber and the orifice. The preparation of nomographs involved using the SWMM (Storm Water Management Model) program with the application of numerical calculations’ results of a differential equation for the stormwater volume balance. The performed analyses confirm a high level of similarity between the results of calculating the reservoir volume obtained by using the above mentioned program and using the developed nomographs. The examples of calculations presented in the paper confirm the application aspects of the discussed method of designing the detention reservoir. Moreover, based on the conducted analyses it was concluded that the inflow hydrograph described by the gamma distribution has the greatest impact on the reservoir’s storage volume, whereas the hydrograph whose shape in the rise and recession phases is described by the power function has the smallest effect.
Effect of 3-Months Home-Based Exercise Program on Changes of Cognitive Functioning in Older Adults Living in Old People’s Home
Authors: Nemček Dagmar , Simon Alexander 
Published: May 2016

Summary
The aim of the study was to determine the effect of regular participation in home-based exercise programme on cognitive functioning changes in institutionalised older adults. Two groups of participants were recruited for the study: experimental (n = 17) in mean age 76 ± 5.6 years, who participated in home-based exercise program and control (n = 14) in mean age 80 ± 4.2 years. The standardised Stroop Color-Word Test-Victoria version (VST) was used to measure the level of cognitive functions. Group differences were analyzed with Mann-Whitney U-test for independent samples and for differences between pre-measurements and post-measurements on experimental and control group we used non-parametric Wilcoxon Signed - Rank Test. The level of significance was α < 0.05. Application of 3-months home-based exercise program significantly improved the cognitive functions only in one (Word condition; p<0.01) from three VST conditions in institutionalised older adults. That’s why we recommend longer participation in home-based exercise program, at least 6- months, with combination of various types of cognitive interventions, like concepts of cognitive training, cognitive rehabilitation, and cognitive stimulation to improve cognitive functioning in older adults living in old peoples’ homes.

Summary
The aim of the research was to determine the differences between real body mass index and perceived body-size among adolescent girls from selected secondary schools. We chose the classes from the 4-year secondary school in Bratislava. Girls involved in research were aged between 15 and 18 years. They have been measured in height and weight during the physical education lessons. We calculated the body mass index (BMI). While having them measured, they subsequently received a questionnaire with silhouettes of female figures. They identified one of the body-size about which they felt that most resembling their own body. We found the differences between real BMI and perceived body-size. From the results of our research, we can say that from all of girls (92) only 22 were seen the illustrated female body approximately at the same range as their real BMI. Test of good match - chi square not confirmed 1 % neither 5 % level of statistics significance.

Published: May 2016

Abstract
This paper presents the analysis of numerical modeling results of the influence of mining exploitation influence on the deformations of the area surface, with the use of an anisotropic elasto-plastic ubiquitous joint model and the transversely isotropic elastic model. The comparison of computer modeling results and geodetic measurements shows that with the use of transversely isotropic elastic model and ubiquitous joint model there is a possibility of the simultaneous description of both perpendicular and horizontal displacements of the area surface, caused by mining exploitation.
Investigation of Geotechnical Parameters Effect on Open Pit Mining Operation Cost (Case Study: Angouran Mine)
Authors: Taherkhani Hamidreza , Doostmohammadi Ramin 
Published: May 2016

Abstract
Properties of intact rock and discontinuities structures are the most important variables affecting mining operations. A comprehensive review of research concerning the direct effect of geotechnical parameters on changes of total exploitation cost in open-pit mines are not provided since now. In this paper, the influence of geotechnical properties of rock mass on total cost of mining operations in Angouran (the largest lead and zinc mine in Middle East located at south western province of Zanjan, Iran) is examined. At first, the classified components of slope mass rating (SMR) and then all exploitation costs (total costs of drilling operation, blasting, bulldozers work, loading and hauling) in mining blocks are surveyed. Then, an equation for determining the correlation between geotechnical properties and total cost using multivariate linear regression is proposed. Eventually, conducting sensitivity analysis revealed that the variation of joints dip is the most effective parameter in change of mining operation cost.

Published: May 2016

Abstract
Since the accession of the Visegrad Group of countries (V4) to the European Union, the importance of clusters has increased. With growing global competitiveness and EU 12 trends, a gradual awareness of creative industries is observed in V4 countries. Therefore, this article analyses creative clusters and factors conditioning their establishment and development. On the basis of a literature review and a questionnaire survey, a mapping of creative clusters was conducted. In addition, catalysts, main motives and key factors in the process of their establishment were identified, as were the activities and factors hampering their development. The scheme of cluster development is presented as the outcome of the qualitative analysis, along with a comparison to findings of other studies. Research findings show that trust building and administrative obstacles are among the main barriers, especially for design clusters and cultural clusters.
Geographical mobility among retired US migrants living in the Northwestern region of Mexico bordering California, US
Authors: Lardiés-Bosque Raúl 
Published: May 2016

Abstract
Mexico has become a regular destination for retirees coming from the USA. To date certain aspects of this group of migrants have been analysed, but little is known about those who have changed their place of residence to the Mexico- US border. In this article, the geographical mobility among retired US migrants living in the coastal area of northern Baja California, Mexico, is analysed. Firstly, reasons for retirees moving from the USA to this area are considered, and secondly, the contacts and relationships maintained with the country of origin, measured by the mobility which takes place between both countries; attention will be given to the reasons for these frequent trips, their periodicity, the means of transport used and the impacts. The main source of analysis will be 29 in-depth interviews conducted in 2009 with pensioners living in coastal municipalities of this northern area of Mexico.
