Authors: Ferrari Silvano , Striano Rosa , Lucking Eric , Pillastrini Paolo , Monticone Marco , Vanti Carla 
Published: December 2019

AbstractBackgroundHigh pain self-efficacy and low kinesiophobia seem related to a better prognosis in patients complaining of low back pain (LBP). The literature stresses the potential negative effects of anatomical defect diagnosis (e.g. lumbar spondylolisthesis) on the psychological profile. The aim of this study is to investigate the relationships between awareness of having a spondylolisthesis, pain self-efficacy and kinesiophobia.MethodsA secondary retrospective analysis was done. Ninety-eight subjects with subacute and chronic LBP were included: 49 subjects with diagnosed symptomatic lumbar spondylolisthesis and 49 subjects with diagnosed non-specific LBP. The pain self-efficacy measured with the Pain Self-Efficacy Questionnaire and the fear of movement measured with the Tampa Scale of Kinesiophobia were considered variables to investigate, whereas diagnosis and demographic/clinical variables were considered predictors or potential confounders.ResultsBy comparing the two groups, the awareness of having a spondylolisthesis did not significantly influence neither pain self-efficacy (p = 0.82), nor kinesiophobia (p = 0.75). Higher perceived pain reduces pain self-efficacy and increases kinesiophobia in both groups (p = 0.002 and p = 0,031 respectively).ConclusionsIt seems that the awareness of an anatomical defect as spondylolisthesis does not significantly affect the beliefs of carry out activities and movements despite the pain. Other studies with wider samples are required, to confirm these preliminary results.
Surgically-induced brain injury: where are we now?
Authors: Travis Zachary D. , Sherchan Prativa , Hayes William K. , Zhang John H. 
Published: December 2019

AbstractNeurosurgical procedures cause inevitable brain damage from the multitude of surgical manipulations utilized. Incisions, retraction, thermal damage from electrocautery, and intraoperative hemorrhage cause immediate and long-term brain injuries that are directly linked to neurosurgical operations, and these types of injuries, collectively, have been termed surgical brain injury (SBI). For the past decade, a model developed to study the underlying brain pathologies resulting from SBI has provided insight on cellular mechanisms and potential therapeutic targets. This model, as seen in a rat, mouse, and rabbit, mimics a neurosurgical operation and causes commonly encountered post-operative complications such as brain edema, neuroinflammation, and hemorrhage. In this review, we elaborate on SBI and its clinical impact, the SBI animal models and their clinical relevance, the importance of applying therapeutics before neurosurgical procedures (i.e., preconditioning), and the new direction of applying venom-derived proteins to attenuate SBI.

Published: December 2019

Abstract
Background
Cognitive overload can impair learning, and different factors might affect cognitive load during simulation-based training. In this study, we investigate the role of failure in repeated practice of virtual reality (VR) simulation of hip fracture surgery on cognitive load (CL) estimated by secondary-task reaction time test and two questionnaires.

Methods
The VR simulation training program consisted of three competency levels of increasing complexity starting with the placement of a Kirschner wire in a fractured hip of one patient, adding clinical variability at the intermediate level, and performing the entire dynamic hip screw procedure in 24 different patients at the highest level. Thirteen consecutive passed simulations were required to advance to the next level. Performance was measured as passing/failing a procedure and the number of failed procedures within the latest three and five simulations. CL was measured objectively using reaction time testing during simulation and subjectively using the NASA-TLX and PAAS questionnaires. The study was carried out at a simulation center from November 2016 to March 2019. Forty-two first-year orthopedic surgery residents from the Central Denmark Region and the North Denmark Region participated in the training program.

Results
A failing performance in the simulated procedure was associated with a higher CL than passing a procedure. The subjective CL estimates were affected by the number of failures during last three and five procedures with a higher number of failures being associated with a higher CL. In contrast, relative reaction time estimates of CL were not affected by previous failures.

Conclusions
Questionnaires for estimation of CL seem to be affected by participant frustration after failure—a meta-cognitive “carry-over” effect. This could be a general limitation of the subjective questionnaire approach to estimate CL. Reducing CL through instructional design and handling of participant frustration might improve the learning outcome of simulation training programs.

AbstractBackgroundTranscatheter aortic valve implantation (TAVI) has evolved to be a treatment of choice in high-risk patients with aortic stenosis (AS). However, it is not known whether TAVI is safe and beneficial for the creation of arteriovenous fistula for maintenance hemodialysis in high-risk patients with severe AS.Case presentationA 91-year-old woman was referred to our hospital due to oligoanuria and progressive renal dysfunction. She was diagnosed with anti-glomerular basement membrane (GBM) disease. She had hypertension, chronic kidney disease stage G3b, and AS. We chose not to perform immunosuppressive therapy and plasmapheresis for anti-GBM disease because the risk of death outweighed the benefit of treatment. Hemodialysis with a venous catheter was initiated for the renal indication. As she showed severe AS, she had a risk of cardiac decompensation after arteriovenous fistula creation for dialysis. Following the clinical decision-making process, she underwent TAVI. Although she required the implantation of a cardiac pacemaker for an advanced atrioventricular block that occurred 11 days after TAVI, arteriovenous fistula was successfully created thereafter. She could undergo maintenance hemodialysis using arteriovenous fistula.ConclusionsTAVI is safe and beneficial for the creation of arteriovenous fistula shortly after initiating acute hemodialysis using a catheter in a very old patient with anti-GBM disease.
Design ecologies: sustaining ethno-cultural significance of products through urban ecologies of creative practice

Published: December 2019

AbstractThis paper presents an account of field research and its findings from an international knowledge exchange project entitled Design Ecologies: Sustaining ethno-cultural significance of products through urban ecologies of creative practice, jointly funded by the UK’s Arts and Humanities Research Council (AHRC) and the Chinese Academy of Social Sciences (CASS), Beijing. The contribution of this paper is to effectively communicate the processes, mechanisms and benefits of an academic knowledge exchange programme. In this case, six exchange visits were carried out, three to China by the British team and three to the UK by the Chinese team. These visits offered opportunities for both teams to gain insights into a variety of heritage sites and craft practices, as well as to the wider policy landscapes in each country. We found that the use of certain terms, like ‘creative industries’, to refer to traditional craft practices and other heritage related activities can be problematic as they tend to emphasise their instrumental rather than their intrinsic value. The Chinese team found the importance and significance of volunteers within the UK’s cultural heritage landscape to be very different from that of China, which does not have a history of volunteering. On the other hand, China supports its Intangible Cultural Heritage through adoption of the UNESCO Convention for the Safeguarding of the Intangible Cultural Heritage, hereafter referred to as the UNESCO Intangible Cultural Heritage (ICH) programme or UNESCO convention (UNESCO 2019b; Cominelli and Greffe 2012); in contrast, the UK has not ratified the UNESCO convention. The China team commented on the UK’s approach to heritage that keeps a sense of ‘living’ heritage, e.g. The English Lake District is a UNESCO World Heritage Centre in which people still live and work. In China, such areas are often depopulated to preserve the heritage and focus on tourism. The British team identified opportunities for design contributions in the visualisation of interrelated and interdependent “ecosystems” of design and production, as observed in Jingdezhen Ceramics Factory. Also, at Taoxichuan Creative Zone design was already being used effectively for the design of artefacts, points of sale, branding and packaging. There is much potential for this to be explored and developed further with different case studies in the UK and China. A shared understanding was developed from the knowledge exchange visits and visit reports created by each of the respective teams. These led to a set of conclusions, insights and themes. Finally, this project has already paved the way for a further Arts and Humanities Research Council (AHRC) research project entitled Located Making, in collaboration with the Beijing Institute of Fashion Technology and Ningxia University.
Nutrient dynamics in decomposing litter from four selected tree species in Makurdi, Benue State, Nigeria
Authors: Okoh Thomas , Edu Esther 
Published: December 2019

Abstract
Background
Nutrient release during litter decomposition was investigated in Vitex doniana, Terminalia avecinioides, Sarcocephallus latifolius, and Parinari curatellifolius in Makurdi, Benue State Nigeria (January 10 to March 10 and from June 10 to August 10, 2016). Leaf decomposition was measured as loss in mass of litter over time using the decay model Wt/W0 = e−kd t, while $$ \mathrm{Kd}=-\frac{1}{t} In\left(\frac{Wt}{W0}\right) $$Kd=−1tInWtW0 was used to evaluate decomposition rate. Time taken for half of litter to decompose was measured using T50 = ln 2/k; while nutrient accumulation index was evaluated as NAI =$$ \left(\frac{\omega t\ Xt}{\omega \mathrm{o}X\mathrm{o}}\right). $$ωtXtωoXo.

Results
Average mass of litter remaining after exposure ranged from 96.15 g, (V. doniana) to 78.11 g, (S. lafolius) in dry (November to March) and wet (April to October) seasons. Decomposition rate was averagely faster in the wet season (0.0030) than in the dry season (0.0022) with P. curatellifolius (0.0028) and T. avecinioides (0.0039) having the fastest decomposition rates in dry and wet seasons. Mean residence time (days) ranged from 929 to 356, while the time (days) for half the original mass to decompose ranged from 622 to 201 (dry and wet seasons). ANOVA revealed highly significant differences (p < 0.01) in decomposition rates and exposure time (days) and a significant interaction (p < 0.05) between species and exposure time in both seasons.

Conclusion
Slow decomposition in the plant leaves implied carbon retention in the ecosystem and slow release of CO2 back to the atmosphere, while nitrogen was mineralized in both seasons. The plants therefore showed effectiveness in nutrient cycling and support productivity in the ecosystem.
Are asylum seekers more likely to work with more inclusive labor market access regulations?
Authors: Slotwinski Michaela , Stutzer Alois , Uhlig Roman 
Published: December 2019

AbstractIn the face of recent refugee migration, early integration of asylum seekers into the labor market has been proposed as an important mechanism for easing their economic and social lot in the short as well as in the long term. However, little is known about the policies that foster or hamper their participation in the labor market, in particular during the important initial period of their stay in the host country. In order to evaluate whether inclusive labor market policies increase the labor market participation of asylum seekers, we exploit the variation in asylum policies in Swiss cantons to which asylum seekers are as good as randomly allocated. During our study period from 2011 to 2014, the employment rate among asylum seekers varied between 0 and 30.2% across cantons. Our results indicate that labor market access regulations are responsible for a substantial proportion of these differences, in which an inclusive regime increases participation by 11 percentage points. The marginal effects are larger for asylum seekers who speak a language that is linguistically close to the one in their host canton.SummaryInclusive labor market access regulations substantially increase the employment chances of asylum seekers, in particular if the language distance is short.
Evaluation of biological control agents for managing squash powdery mildew under greenhouse conditions
Authors: Elsisi Ahmed A. 
Published: December 2019

AbstractSquash (Cucurbita pepoL.), is one of the most important vegetable crops for human nutriment in Egypt and the world. One of the most serious diseases that infect squash and cause yield losses was powdery mildew, caused byPodosphaera xanthisii. The aim of this study was to investigate the role ofBacillus subtilis,Paenibacillus polymyxa(109cell ml/1),Trichoderma harzianum,T. album,T. virideandT. hamatum(107spore ml/l) for controlling disease under greenhouse conditions. Results indicated that all treatments significantly inhibited the conidial germination ofP. xanthiithan control in vitro and decreased the incidence and disease severity after spraying with the bio-agents on squash plants under greenhouse conditions. The fungicide, Topas-100 (10.0% penconazole “w/v” [(R,S-1-(2-(2,4-dichlorophenyl)-Q pentyl)-1H-1,2,4-triazole]), followed byB. subtiliswas highly significant for decreasing disease incidence (2.8 and 5.3%, respectively) and disease severity percentage (3.5 and 4.8%, respectively) than the control. The activities of biochemical changes, i.e., peroxidase, polyphenol oxidase, and total phenols, were significantly upregulated as results of most treatments. Also, bio-agent treatments caused significant increase in yield characteristics of squash plants such as fruit number/plant and fruit weight/plant than control.B. subtilisrecorded the highest increase (110.9% and 98.7%) in fruit number and fruit weight/plant than control.

Published: December 2019

AbstractBackgroundA study was conducted to investigate changes in oxidative stress indicators of West African dwarf (WAD) goats at different reproductive stages. There are a total of 35 dry does, 30 gravid does at first trimester (40–45 days post-mating), 33 gravid does at second trimester (85–90 days post-mating), 31 gravid does at third trimester (135–140 days post-mating), and 40 postpartum does (30–35 days postpartum). Fastened blood samples were collected from all tagged animals and serum obtained. Serum was assayed for lipid peroxidation, total antioxidant activity, glutathione peroxidase, catalase and superoxide dismutase, serum biochemical, glucose, total protein, albumin, cholesterol, triglyceride, high-density lipoprotein, alkaline phosphatase, alanine aminotransferase, aspartate aminotransferase, urea, and creatinine using standard procedures.ResultsResult revealed that intense metabolic changes were associated with late prepartum and postpartum does as pronounced in oxidative and biochemical indicators of WAD does. Significant differences were found in serum biochemical indices across the different physiological stages of the doe except for triglyceride and low-density lipoprotein. Antioxidant defense is higher at early and mid-gestation and dry does, through low lipid peroxidation and high antioxidant activity as compared to late gestation and lactation does.ConclusionThe observed result shows that the WAD does display oxidative stress during late gestation and lactation owing to intense metabolism. Antioxidant fortification should be employed especially during late gestation and lactation to counteract the oxidative stress in WAD goats.

Abstract
Background
Slow-release fertilizers (SRF) are quite numerous, and diverse group of materials are involved in the improvement of the effectiveness of fertilization, mitigation of the negative impact of fertilizers on the environment, and the reduction of labor and energy consumption connected with the application of conventional fertilizers. The objective of the experiment was to measure vegetative growth parameters and nutritional status of Nonpareil almond young trees under two types of slow-release compound fertilizers: Matador at 30, 60, and 120 kg/Feddan and Nitrophoska at (25, 50, and 100 kg/Feddan. The experiment was conducted in the Experimental Research Station of National Research Centre at Nubaria, El Behera governorate, Egypt, during successive growing seasons 2018 and 2019.

Results
The results indicated that increasing doses of slow-release fertilizer significantly improved vegetative growth of trees. The highest dose of Nitrophoska had significantly higher stem length, diameter, numbers of branches and leaves/trees, leaf area, leaf chlorophyll content, leaf fresh and dry weight while the highest significant of specific leaf dry weight was obtained by applying the highest dose of Matador compared with control trees that received the fast-release fertilizer NPK 19:19:19 at 200 kg/Feddan. Leaf mineral contents of some macro (N, P, K and Mg) and micro elements (Fe, Mn, Zn, and Cu) were significantly increased as a result of application with slow-release fertilizers. Nitrophoska at 100 kg/Feddan gave the highest values of nitrogen, potassium, magnesium, and iron while Matador at 120 kg/Feddan gave the highest value of manganese. Matador at all doses resulted in a significant increment in phosphorus concentration in leaves in both seasons. Nitrophoska at 100 kg/Feddan and Matador at 120 kg/Feddan recorded the highest values of zinc and copper without significant differences between them.

Conclusions
It could be concluded that application with slow-release fertilizers resulted in a positive and significant influence on most investigated vegetative growth measurements and leaf mineral contents of Nonpareil almond trees, since the application with Nitrophoska at 100 kg/Feddan was the most effective treatment for increasing growth measurements and improving leaf nutritional status of Nonpareil almond trees grown under Nubaria condition.
Relationship between risk perception and occupational accidents: a study among foundry workers
Authors: Jafari Mohammad Javad , Saghi Fahimeh , Alizadeh Ebrahim , Zayeri Farid 
Published: December 2019

Abstract
Background
Risk perception is an effective factor in the determining of the incidence of unsafe behaviors and the occurrence of occupational accidents in the workplace.

Objective
The purpose of this study is to determine the relationship between risk perception and occupational accidents among foundry workers in Tehran, Iran.

Methods
In this cross-sectional study, all male workers in a foundry unit were initially selected (n = 245). After applying the study criteria and dismissing incomplete returned questionnaires, only 109 workers were included in the study. The General Health Questionnaire and the Flynn et al. Risk Perception Questionnaire were used to assess the mental health and risk perception of workers, respectively. Data regarding the occupational accidents of workers were also extracted from the accidents’ records of the foundry. Workers with a record of occupational accidents during 2013–2016 were compared with workers without an occupational accident record.

Results
Findings showed that a one-unit increase in the risk perception score resulted into an increase of approximately 33% in the odds of the occurrence of occupational accidents, but this rate was not significant (p = 0.695). In addition, the study found no significant relation between the risk perception score and the frequency of occupational accidents (Spearman’s r = 0.003, p = 0.977).

Conclusion
There is no statistically significant relationship between risk perception and occupational accidents among foundry workers in Tehran, Iran.

Published: December 2019

Abstract
Background
With the development of assisted reproductive technology (ART), diseases believed to be caused by ART have begun to be identified as imprinted disease. However, no conclusion has been reached. So we sought to determine whether ART procedures disturb gene methylation and whether imprinted genes alone are selectively disturbed. To examine whether the constituents of the culture medium contribute to the changes in methylation, we used a mouse model to conduct IVF and comprehensively analyzed 5′–C–phosphate–G–3′ (CpG) by reduced representation bisulfite sequencing (RRBS) using a second-generation sequencer to determine changes in methylation using four types of culture media with different amino acid constituents.

Results
We cultured ova to the blastocyst stage in a mouse model in culture media with four different amino acid constituents. Each culture medium included (1) KSOM culture medium (NoAA), (2) KSOM media + essential amino acids (EAAs), (3) KSOM medium + non-essential amino acids (NEAAs), or (4) KSOM medium + EAAs + NEAAs (AllAA) analyzed by reduced representation bisulfite sequencing. The results showed that (1) there were many regions that maintained hypermethylation with NEAAs, (2) there was little effect of demethylation on reprogramming in the 5′UTR and promoter regions, and (3) specific changes were observed in imprinted genes such as Nnat and Nespas.

Conclusions
Compared with EAAs, NEAAs could protect genes from demethylation caused by reprogramming. On the imprinted genes, methylation of the promoter region of H19 was decreased by NEAAs, suggesting that specific genes were prone to changes in methylation. It was suggested that these changes could provide similar results in humans. Further studies are needed to understand how changes in methylation may affect gene expression profiles.
