Published: December 2020

Background Radiation-associated angiosarcoma of the breast (RAASB) is a serious late consequence caused by breast cancer treatment. Initial symptoms are often inconspicuous, thus contributing to diagnostic delay. Most previous studies of the diagnostic aspects of RAASB are case reports. Purpose To perform a complete review of the imaging findings and biopsy methods in a nationwide RAASB cohort. Material and Methods RAASB patients were identified from a national cancer registry and additional patients were included from our hospital. All available information from imaging (mammogram [MGR], ultrasound [US], magnetic resonance imaging [MRI], and computed tomography [CT]) and biopsies was reviewed. The sensitivity of imaging and biopsy methods for detection of RAASB was calculated. Results Fifty-eight patients with RAASB were found. Fourteen MGR, 30 US, 24 MRI, and 25 CT studies were available for evaluation. The sensitivity of MGR, US, MRI, and CT for detection of RAASB was 43%, 50%, 92%, and 84%, respectively. Superior sensitivity was demonstrated for punch biopsy (84%) and incisional biopsy (93%) compared to fine-needle aspiration cytology (0%) and core needle biopsy (18%). Conclusion MRI and CT have comparable sensitivity for detection of RAASB, while MGR and US are unreliable. However, negative findings in MRI or CT must be interpreted with caution. Punch biopsy and incisional biopsy are the preferred biopsy methods.

Published: December 2020

Background Femoral head collapse and coxa vara lead to internal fixator failure in elderly patients with hip fracture. External fixator application is an optimal choice; however, the existing methods have many disadvantages. Methods Type 31-A1.3 hip fracture models were developed in nine pairs of 1-year-old fresh bovine corpse femur specimens. Each left femur specimen was fixed by a dynamic hip screw (control group), and each right femur specimen was fixed by the slide-poking external fixator (experimental group). Vertical loading and torsion tests were then performed in both groups. Results In the vertical loading experiment, a 1000-N load was implemented. The mean vertical downward displacement of the femoral head in the experimental and control groups was 1.49322 ± 0.116280 and 2.13656 ± 0.166374 mm, respectively. In the torsion experiment, when the torsion was increased to 10.0 Nm, the mean torsion angle in the experimental and control groups was 7.9733° ± 1.65704° and 15.4889° ± 0.73228°, respectively. The slide-poking external fixator was significantly more resistant to compression and rotation than the dynamic hip screw. Conclusion The slide-poking external fixator for hip fractures that was designed and developed in this study can provide sufficient stability to resist compression and rotation in hip fractures.

Background Laminectomy is a traditional method for treating lumbar diseases; however, the destruction of the posterior structures may cause postoperative symptoms. An individualized poly-ether-ether-ketone (PEEK) artificial lamina was designed to reconstruct the posterior structures after laminectomy. This study aimed to explore the biomechanical effects of reconstruction of the posterior structures with an individualized PEEK artificial lamina using validated finite element models. Objective To examine the biomechanical effects of individualized PEEK artificial lamina on postlaminectomy lumbar. Methods A finite element (FE) model of L3-5 was developed based on computed tomography images. Four surgical models (laminectomy, artificial lamina alone, ligament reconstruction, and osseointegration) were constructed, representing different stages of L4 artificial lamina implantation. The range of motion (ROM), intradiscal pressure (IDP), stresses in the annulus fibrosus at the surgical level and cephalad adjacent level, and stresses in the artificial lamina and screws were measured. Results The ROM, IDP, and stresses in the annulus fibrosus of the different artificial lamina models decreased compared to those of the laminectomy model at both surgical and adjacent levels for all motion patterns, most notably in the osseointegration model. In addition, the results of the stresses in the implants showed that the artificial lamina could enhance the lumbar isthmus and disperse the abnormally concentrated stresses after laminectomy. Conclusion The application of a PEEK artificial lamina has the potential to stabilize the postlaminectomy lumbar spine and prevent adjacent segment disease (ASD) and iatrogenic lumbar deformities, resulting in a reduction in the incidence of post-lumbar surgery syndrome.

Published: December 2020

Background Aiming to protect breastfeeding, the World Health Organization released the International Code of Marketing of Breastmilk Substitutes in 1981, which was adopted by the vast majority of the 118 member countries, including Brazil. The Brazilian Code regulates the marketing of infant formulas, baby bottles, teats, pacifiers, milk, and processed complementary food. Research aims (1) To determine if retail stores had violated the Brazilian Code and (2) to analyze factors associated with these violations. Methods This cross-sectional study included all drugstores, supermarkets, and department stores in the Southern Zone of Rio de Janeiro City, Brazil. Trained health professionals observed retail stores for marketed products and violations of the Brazilian Code and then interviewed their managers. Factors associated with the retail stores violating the Brazilian Code (outcome) were analyzed, employing a logistic regression model with 95% Confidence Interval. Results Of the retail stores ( N = 349) evaluated, 62.8% violated the Brazilian Code, ranging from 1 to 37 violations per retail store. The most common promotion strategies were price discounts and special displays. Retail stores being part of a chain store (aOR = 4.59) and their manager receiving visits from industry business representatives (aOR = 2.14) were associated with the presence of violations. Conclusions The prevalence of Brazilian Code violations was high, especially in chain stores. The association between regular visits by industry representatives and violations suggests an indirect influence of manufacturers on the promotion of human milk substitutes. We recommend strengthening compliance with the Brazilian Code through calling on governmental surveillance agencies and civil society mobilization.

Published: December 2020

Background The purpose of this study was to determine agreement with the American Academy of Orthopaedic Surgery Appropriate Use Criteria (AUC) for distal radius fractures (DRFs), before and after their adoption, and secondarily determine predictors of operative management. Methods A single-institution retrospective cohort study comparing patients treated either nonoperatively (115 patients) or operatively (767 patients) for DRFs between May 1, 2008, and May 1, 2018, by 8 hand surgeons was performed. Data included demographics, injury characteristics, DRF radiographic measurements, treatment rendered, and their appropriateness according to the AUC. Statistical testing used the Fisher and χ2 tests, t test, and multiple variable logistic regression, with a significance level of .05. Results Overall, there was a significant increase in AUC agreement for operatively treated DRFs (82.7%-89.3%, P = .01), but no difference in agreement for nonoperatively treated DRFs (12.5%-10.7%, P = .77). Age <80 years, AO classes other than B, intra-articular displacement >1 mm, radial inclination <18°, high-energy mechanism of injury, and greater than 1 week to treatment were independent predictors of operative treatment. The area under the curve for the validated regression model using the aforementioned predictors was 0.82. Conclusion Agreement with AUC for DRFs increased after its adoption for operatively treated, but not for nonoperatively treated, fractures. In addition, a predictive model for operative treatment was developed and validated. Future studies may benefit from further model refinement and testing in other patient cohorts.

Published: December 2020

AbstractBackgroundWe conducted a correlative study for E2399, a function preservation trial for resectable locally advanced oropharynx and larynx cancer, to prospectively assess effects of chemoradiation (CCR) on quality of life (QOL), swallowing and voice. We correlated the results of swallow assessments done via questionnaires and objective assessments by modified barium swallow (MBS).MethodsThe Functional Assessment of Cancer-HN (FACT-HN), the Performance Status Scale – Head and Neck (PSS-HN), swallow assessments (including modified barium swallow studies), and voice assessments: Voice Handicap Index (VHI), the Voice Disability Assessment (VDA), and American Speech-Language Hearing Association’s Functional Communication Measure (FCM) were conducted at baseline and periodically post-treatment for 2 years.ResultsBaseline QOL and swallowing function predicted overall survival. Patients experienced a marked decrease in QOL, swallowing, and speech post CCR although the decrease in vocal function was modest. Function and QOL returned towards baseline in the majority of patients by 12 months post treatment. Less than 10% of patients had severe dysphagia and were PEG dependent at 12 months post treatment. There was a high degree of correlation between the FACT-HN and PSS-HN swallow items. Statistically significant correlations were found between subjective and objective measures of swallow function.ConclusionsPatients experience marked loss in swallowing function post CCR which returned to baseline in the majority of patients. The correlations between the FCM and self-report swallow items on the PSS and FACT-HN appear to be sufficiently strong to justify their use as a surrogate marker for swallowing disability in large therapeutic trials.
Corrosion behavior of 15CrMo steel for water-wall tubes in thermal power plants in the presence of urea and its byproducts

Published: December 2020

Abstract
The corrosion behavior of 15CrMo used for water-wall tubes was studied in various urea-containing solution to determine the corrosion problem of water-wall tubes caused by urea in a coal-fired power plant. Urea decomposition tests, together with corrosion experiments, were carried out. The temperature was 320 °C, and the concentrations of urea were 70, 140, 280, 560 and 840 mg/L. Weight loss experiments and surface analysis indicated that the corrosion of 15CrMo steel is mainly manifested as localized corrosion. The corrosion rate of 15CrMo steel increased with the increase of urea concentration, and the maximum value reached 0.686 mm/y (mm per year) when the urea concentration was 840 mg/L. Electrochemical analysis suggested that the corrosion rates of 15CrMo were enhanced substantially by urea decomposition products. The results of UPLC-ESI-MS, infrared spectroscopy and X-ray diffraction showed that urea solution produced corrosive ions NH2COO− during the decomposition process, which caused the corrosion of 15CrMo. Results provided evidence as relevant explanation for the corrosion behavior of 15CrMo in urea solution.
Rechtspopulismus und organisierte Zivilgesellschaft
Authors: Schroeder Wolfgang , Greef Samuel , Elsen Jennifer Ten , Heller Lukas 
Published: December 2020

Zusammenfassung
Rechtspopulist*innen intervenieren in die Zivilgesellschaft, wobei sie die etablierten Akteure auf der Basis ihrer korporatistischen Einbindung als Teil des Establishments angreifen und bestehende Konflikte nach populistischer Logik umdeuten. Die Reaktionen der zivilgesellschaftlichen Organisationen erfolgen situativ und changieren zwischen wertebezogener Abgrenzung und inhaltlicher Auseinandersetzung. Die Zivilgesellschaft ist herausgefordert, ihre inneren Widersprüche zu bearbeiten, um nicht als Einfallstor für, sondern als Schutzfaktor gegen Rechtspopulismus zu wirken.

Published: December 2020

Abstract

Objectives
Patients with celiac disease had significantly decreased bone mineral density even in patients with no gastrointestinal symptoms. Only few bone studies are available on pediatric patients with celiac disease.

Methods
Forty-six patients underwent measurement of areal bone mineral density (aBMD) by dual-energy X-ray absorptiometry (DXA) before the initiation of gluten-free diet. Anthropometric, laboratory and DXA measurements at baseline and at sixth month of the treatment were compared.

Results
The frequency of low aBMD Z-score (≤−1 SDS) in both or any site was found to be 78.2% in this study. Of 16 patients with an aBMD Z-score of <−2 SDS five gained more than 1 SDS, and one gained more than 2 SDS. Nine of 20 patients with an aBMD Z-score of <−1 SDS completely normalized.

Conclusions
The results of the study showed that low BMD is common in children with celiac disease at the time of diagnosis and could improve in a short period of six months with a strict gluten-free diet and adequate supplementation of calcium and vitamin D.
PALEOECOLOGICAL IMPLICATIONS OF LARGE-SIZED WILD BOAR TRACKS RECORDED DURING THE LAST INTERGLACIAL (MIS 5) AT HUELVA (SW SPAIN)

ABSTRACTWell-preserved tracks of the wild boar Sus scrofa are described from the Matalascañas Trampled Surface (MTS) in the upper Pleistocene aeolian basal unit of the El Asperillo Cliff, Huelva (southwestern Spain). These are the first published tracks of suid pigs in the fossil record, here formally described as Suidichnus galani igen. and isp. nov. A revision of valid artiodactyl ichnogenera is provided for comparison. The large size of wild boar found in the Late Pleistocene of Spain contradicts the general trend towards smaller size known for the evolution of the species and the Bergmann's ecogeographical rule for the extant subspecies. In the present case, the remarkable large size that can be reached by these tracks is discussed as an ecomorphological adaptation of wild boars to either resource bonanza, and/or predation pressure during the Last Interglacial. The large S. scrofa scrofa identified in MTS corresponds to some of the earliest evidences known to this subspecies in Iberia.
The Art of Design: from philosphy to practice
Authors: Kathryn Jane Moore  
Published: December 2020

This exposition sets out evidence of the research undertaken over the last decade to understand the implications beyond the academy of the new paradigm presented in ‘Overlooking The Visual: Demystifying the Art of Design’ (2010), leading to
‘Towards New Research Methodologies in Design: Shifting Inquiry Away from the Unequivocal Towards the Ambiguous’ (2018). The exposition shows the process of developing ‘The Art of Design’ at a regional scale through a number of sequential case studies. Requiring investigative and analytical drawing from a position of knowledge and the reimagining and re-presenting of places in order to rekindle and reinvent the connection between communities and the space they inhabit, recognising the pride people take in that space, its cultural identity, be it urban, suburban or rural, is very much a modern, contemporary view of how our landscapes work.

The ideas expressed in the visual narratives have engaged a wide range of decision makers and are shifting perceptions, planning policy and practices at a local, national and international level. The student work exhibited in 2019 (BCU) explored the spatial implications of the ethos of the West Midlands National Park focused on specific locations and was vital in persuading key regional and national stakeholders of the significance of this new approach.

This predominantly visual exposition presents the transformative practice-based research process manifest as visual artefacts from philosophy to practice interrogating the art of design.
Empirical study on big data of workplace spirituality theory method and computational simulation
Authors: Cao EnWei , Green Jim 
Published: December 2020

Abstract
Workplace spirituality, job engagement, and perceived organisational support have become the themes over which heated discussion is held in the fields of management and public research. With the development of science and technology and the arrival and upgrading of burgeoning technologies, the competition among enterprises has been aggravated, while the employee's job engagement has become one of the key aspects to keep the competitive edge. By taking workplace spirituality as the premise variable of job engagement and perceived organisational support, the influences of workplace spirituality, perceived organisational support, and job engagement are discussed in this paper. In addition, by taking perceived organisational support as the regulated variable, a theoretical model was built and the regulating effect of perceived organisational support on workplace spirituality and job engagement was discussed. The empirical data of the model was obtained through 187 questionnaires. Data analysis and research hypothesis was implemented through SPSS23.0, theory method, and computational simulation. In sum, workplace spirituality and job involvement are remarkable and are positively associated with each other. Perceived organisational support plays a role in regulating the job engagement. These results provide new perspectives for exploring unemployment problems existing due to lack of job engagement. The organisation can intervene in employees’ work by cultivating workplace spirituality.

Published: December 2020

Abstract
The influence of the sintering temperature on the structure and on the hysteresis loops of Fe3+ doped Pb(ZrxTi1-x)O3 system has been investigated. Three compositions have been selected in the following mode: one in rhombohedral region, one in MPB region and one in tetragonal region have been obtained by solid state reaction technique. Sintering has been carried out at 12000C and 12500C respectively. The nature of the phases has been investigated in detail using X-ray diffraction analysis (XRD). All the sintered samples reveal a perovskite type structure. The surfaces have been lapped and metalized in order to obtaine the hysteresis loops at room temperature. The results showed a similar behaviour with “hard” PZT ceramics.

Published: December 2020

Abstract
Antifungal of bee products have been shown to be protective against microbial biofilms invasion Sahara honey and propolis were applied as an antimicrobial in treatment for many infections in Algeria. In this study, Fourier transform infrared spectroscopy (FTIR) analysis was utilized to characterize the chemical structures and functional groups. In addition, in this study, we determined the anti-candida activity of honey used alone or in combination with propolis. Proteins, carbohydrates, carboxylic acids, free amino acids, cellulose and lipids, ketones and phenol compounds were identified by FTIR analysis. Combination of Sahara honey and propolis increased antifungal efficacy, compared to compounds tested alone. Propolis increased the anti-candidal effect of Sahara honey. In addition, the treatment of Sahara honey and Propolis-Sahara honey catheters with a Candida albicans biofilms reduced biofilm formation after 24 and 48-h exposure period. The results provide evidence that honey/propolis combination may help in designing a more potent novel, natural antibiofilm blend at sufficiently low concentrations in medical domain.

Authors: Juričić Vedran , Radošević Matea , Fuzul Ena 
Published: December 2020

Abstract

Background
Blockchain technology has gained a great public interest due to the appearance of cryptocurrencies, a digital asset used for exchanging funds. Although blockchain calculations offer the benefits of security and reduced costs, blockchain is still strongly criticised for its lack of usefulness and resource-heavy consumption.

Objectives
The aim of this research is to provide different insights into blockchain technology and to propose NP-complete problems as a suitable alternative to the current consensus algorithm.

Methods/approach
This research discusses the current state of proposed alternatives, projects such as distributed volunteering for scientific purposes and different consensus algorithms within cryptocurrencies but focusing on incorporating NP-complete problems as a secondary, more useful option.

Results
Using the properties of NP-complete problems, it is possible to solve various problems in different areas, such as science, biology, medicine and finance, but also to improve business processes, optimize markets, payments and supply chains while decreasing environmental costs.

Conclusions
This paper shows that the alternative mechanisms are being developed and used to substitute an existing Blockchain algorithm with a more efficient one. It also suggests further investigation in this area because the alternatives greatly improve blockchain’s usability and efficiency.
