Abstract
Purpose
The purpose of this study is to report a new mini-invasive technique to remove an intracranial bullet in a child by using O-arm for intraoperative neuronavigation.

Case report
A 14-year-old refugee boy had suffered a shooting injury 4 years earlier. O-arm imaging-assisted neuronavigation during craniotomy was performed in order to remove a bullet from the intracranial space in a paediatric patient.

Conclusion
Navigation using O-arm is a feasible method in removing a foreign material in a child and gave an accurate location of the bullet in the adopted surgical operation position without significant imaging artefacts.

Abstract
Background
Laparoscopic resections for rectal cancer are routinely performed in high-volume centres. Despite short-term advantages have been demonstrated, the oncological outcomes are still debated. The aim of this study was to compare the oncological adequateness of the surgical specimen and the long-term outcomes between open (ORR) and laparoscopic (LRR) rectal resections.

Methods
Patients undergoing laparoscopic or open rectal resections from January 1, 2013, to December 31, 2019, were enrolled. A 1:2 propensity score matching was performed according to age, sex, BMI, ASA score, comorbidities, distance from the anal verge, and clinical T and N stage.

Results
Ninety-eight ORR were matched to 50 LRR. No differences were observed in terms of operative time (224.9 min. vs. 230.7; p = 0.567) and postoperative morbidity (18.6% vs. 20.8%; p = 0.744). LRR group had a significantly earlier soft oral intake (p < 0.001), first bowel movement (p < 0.001), and shorter hospital stay (p < 0.001). Oncological adequateness was achieved in 85 (86.7%) open and 44 (88.0%) laparoscopic resections (p = 0.772). Clearance of the distal (99.0% vs. 100%; p = 0.474) and radial margins (91.8 vs. 90.0%, p = 0.709), and mesorectal integrity (94.9% vs. 98.0%, p = 0.365) were comparable between groups. No differences in local recurrence (6.1% vs.4.0%, p = 0.589), 3-year overall survival (82.9% vs. 91.4%, p = 0.276), and disease-free survival (73.1% vs. 74.3%, p = 0.817) were observed.

Conclusions
LRR is associated with good postoperative results, safe oncological adequateness of the surgical specimen, and comparable survivals to open surgery.
A procedure for the introduction of leanness into a company
Authors: Cimermančič Davorin , Kušar Janez , Berlec Tomaž 
Published: January 2021

AbstractChanging a traditional company into a lean one is a very complex and time-consuming process that needs to be addressed in an appropriate way, otherwise the project of introduction of leanness into a company may fail on the one hand and even have a negative impact on business operations of the company on the other. When introducing a change, a step-by-step procedure leading to a progress may be of great help. The paper outlines a general procedure of leanness, an important part of which is a lean agent. A portfolio analysis is also used as a measure of leanness or as an indicator of the desired direction. The applied working methods were mainly active workshops and interviews with employees. The procedure has been tested on an example of a Slovene company; first, the existing situation is outlined, then the leanness steps taken according to the procedure and the final result after the first transition of the procedure.
The Importance of Body Part Labeling to Enable Enterprise Imaging: A HIMSS-SIIM Enterprise Imaging Community Collaborative White Paper
Authors: Towbin Alexander J. , Roth Christopher J. , Petersilge Cheryl A. , Garriott Kimberley , Buckwalter Kenneth A. , Clunie David A. 
Published: January 2021

AbstractIn order for enterprise imaging to be successful across a multitude of specialties, systems, and sites, standards are essential to categorize and classify imaging data. The HIMSS-SIIM Enterprise Imaging Community believes that the Digital Imaging Communications in Medicine (DICOM) Anatomic Region Sequence, or its equivalent in other data standards, is a vital data element for this role, when populated with standard coded values. We believe that labeling images with standard Anatomic Region Sequence codes will enhance the user’s ability to consume data, facilitate interoperability, and allow greater control of privacy. Image consumption—when a user views a patient’s images, he or she often wants to see relevant comparison images of the same lesion or anatomic region for the same patient automatically presented. Relevant comparison images may have been acquired from a variety of modalities and specialties. The Anatomic Region Sequence data element provides a basis to allow for efficient comparison in both instances. Interoperability—as patients move between health care systems, it is important to minimize friction for data transfer. Health care providers and facilities need to be able to consume and review the increasingly large and complex volume of data efficiently. The use of Anatomic Region Sequence, or its equivalent, populated with standard values enables seamless interoperability of imaging data regardless of whether images are used within a site or across different sites and systems. Privacy—as more visible light photographs are integrated into electronic systems, it becomes apparent that some images may need to be sequestered. Although additional work is needed to protect sensitive images, standard coded values in Anatomic Region Sequence support the identification of potentially sensitive images, enable facilities to create access control policies, and can be used as an interim surrogate for more sophisticated rule-based or attribute-based access control mechanisms. To satisfy such use cases, the HIMSS-SIIM Enterprise Imaging Community encourages the use of a pre-existing body part ontology. Through this white paper, we will identify potential challenges in employing this standard and provide potential solutions for these challenges.

Published: January 2021

AbstractThe aim of this study was to assess genotype by environment interaction for grain yield, plant height and thousand-grain weight in winter triticale cultivars by the additive main effects and multiplicative interaction (AMMI) model. The study comprised of ten winter triticale varieties i.e.: Algoso, Baltiko, Grenado, Magnat, Moderato, Pawo, Todan, Trimester, Trismart and Witon. Field trials were performed at seven locations in three years (21 environments) in a randomized complete block design, with two replicates at two levels of cultivation technology (standard – A1 and intensive – A2). Field experiments were carried out as part of Post Registration Variety Trials in Wielkopolska region. AMMI analyses revealed significant genotype and environmental effects as well as genotype by environmental interaction with respect to all three observed traits in both levels of cultivation intensity. The cultivars Algoso, Baltiko and Trimester are recommended for further inclusion in the breeding programs because of their stability and good average values of observed traits.
An Optimization Algorithm for Exponential Curve Model of Single Pile Bearing Capacity
Authors: Ma Hongmei , Peng Cheng , Gan Jinying , Deng Yonghong 
Published: January 2021

AbstractThe ultimate bearing capacity of single pile is very important to engineering safety, so correctly predicting its value becomes an important part of engineering safety. Based on the traditional exponential curve model, a parameter optimization algorithm of the exponential curve model of single pile bearing capacity, which combines the golden section method and the linear least square method, is proposed. In order to verify the reliability of the proposed optimization algorithm, the measured data of the building engineering in the literature were optimized and calculated. Through comparison, it is found that the optimization algorithm is closer to the measured value than the traditional exponential curve model algorithm, which can better guide the engineering practice, and verify the effectiveness and superiority of the proposed parameter optimization method.
Career-first: an approach to sustainable labour market integration
Authors: Fuertes Vanesa , McQuaid Ronald , Robertson Peter J. 
Published: January 2021

AbstractActive labour market policies aim at supporting people entering and, importantly, remaining in the labour market. Initiatives to this end have often been characterised by a mixture of ‘human capital’ and ‘work-first’ approaches, although both have had a relatively limited effect on achieving job sustainability for those most distant from the labour market. This paper explores a distinctive approach to supporting job entry and sustainable employment that we have called ‘career-first’. The career-first approach to labour activation draws on three separate traditions of thinking: labour market, career development, and the capability literatures. Common ground is found in these three perspectives so each complements the weaknesses of the others. A career-first approach may be able to help deliver benefits to the individual, their family, and the wider society.
Gastric Electrical Stimulation for Treatment of Refractory Gastroparesis: the Current Approach to Management
Authors: Shanker Aaron , Bashashati Mohammad , Rezaie Ali 
Published: January 2021

AbstractPurpose of ReviewGastroparesis is one of the more challenging entities in the landscape of gastroenterology, posing difficulties for both patients and physicians with regard to effective management and therapies. In this article, we reviewed various gastroparesis treatment options, with an emphasis on gastric electrical stimulation (GES).Recent FindingsGES has demonstrated a significant reduction of cardinal symptoms in refractory gastroparetic patients, particularly nausea and vomiting, across multiple studies. However, GES has not been shown to conclusively decrease gastric emptying time in these patients. Such finding has led the investigators to analyze the impact of combining GES with pyloroplasty. While this treatment pathway is nascent, its results thus far reveal an amplified improvement of gastroparesis symptomatology in addition to significant reduction of gastric transit, compared to GES by itself.SummaryLimited treatment choices are available for refractory gastroparesis. Combining GES with pyloroplasty holds promise but requires further assessment in large-scale trials to fully evaluate the risks and benefits.
Rain Erosion Maps for Wind Turbines Based on Geographical Locations: A Case Study in Ireland and Britain
Authors: Pugh K. , Stack M. M. 
Published: January 2021

AbstractErosion rates of wind turbine blades are not constant, and they depend on many external factors including meteorological differences relating to global weather patterns. In order to track the degradation of the turbine blades, it is important to analyse the distribution and change in weather conditions across the country. This case study addresses rainfall in Western Europe using the UK and Ireland data to create a relationship between the erosion rate of wind turbine blades and rainfall for both countries. In order to match the appropriate erosion data to the meteorological data, 2 months of the annual rainfall were chosen, and the differences were analysed. The month of highest rain, January and month of least rain, May were selected for the study. The two variables were then combined with other data including hailstorm events and locations of wind turbine farms to create a general overview of erosion with relation to wind turbine blades.
Labour market performance of young migrant workers with heterogeneous educational trajectories in China
Authors: Xiang Nan , Zhang Yuxi 
Published: January 2021

AbstractSuccessful global cities present a spectrum of development strategies but share the benefit of the reciprocal dynamics between tailored education systems and matching labour markets. This paper examines burgeoning cities in China and investigates the effects of the heterogeneous educational trajectories of young migrant workers in urban China on their labour market performance. Drawing on the National Migrant Dynamics Monitoring Survey, this paper finds striking wage variations among the young migrant population. Migrant workers who attended high schools in current receiving cities earned less than their counterparts who received senior-secondary education elsewhere. Students following the academic track were better off than students following the vocational track. To further explore what has prevented the urban labour market from rewarding migrants who studied in a receiving city, where the education system is expected to better cater to the city’s specific industrial needs, we tested and found evidence of the mediating effects of job industry and occupation. In addition to engaging with empirical debates in the field, this paper develops a theoretical framework to model how the qualitative attributes of an education system affect wage variations among migrant workers.
Design improvement and experimental study on shell and tube condenser for bio-oil recovery from fast pyrolysis of wheat straw biomass
Authors: Salvi B. L. , Soni T. , Jindal S. , Panwar N. L. 
Published: January 2021

AbstractIn this study, the design improvement was done in a shell and tube condenser for improved heat transfer and condensation of bio-oil vapour. The developed condenser has split shell and segmental baffles, which divide the shell in various zones and condensate collection points. The fast pyrolysis of wheat straw was done and the bio-oil vapour condensate collected from various outlets located at bottom of condenser shell. From experimental results it was found that production of bio-oil increased from 10.2 to 20.8% with increase in cooling water flow rate from 1000 to 2500 L/h; but, further increasing it beyond 2500 L/h provide marginal effects on production of bio-oil. The production of bio-oil increased from 15.2 to 20.7% as sweep gas flow rate was increased from 20 to 40 L/min at 2500 L/h of cooling water flow rate. But, further increase in sweep gas flow rate beyond 40 L/min resulted in to decrease in production of bio-oil. The novelty of this work is development of improved condenser with segmental baffles, which help in fractional condensation of bio-oil vapour, split shell for cleaning of outer surface of the cooling water tubes and compact design of condenser for optimal condensation of bio-oil.
Numerical and experimental investigation of alumina-based nanofluid effects on double-pipe heat exchanger thermal performances
Authors: Bendaraa A. , Charafi My. M. , Hasnaoui A. 
Published: January 2021

AbstractIn this study, we investigate the thermal behaviour of nanofluids in a double-pipe heat exchanger. It is about a counterflow configuration, designed to cool a lubrication unit of a thermoelectric power plant. The subject of this work is to evaluate the thermal performances of the exchanger by using a nanofluid based on alumina suspension comparing with deionized water. In order to evaluate the thermal performance of the studied configuration, we carried out numerical experiments in an application developed on COMSOL Multiphysics environment, these experiments are utilized to show the feasibility of this application. As result, we found that the nanofluid with an increase in its volume fraction leads to an increase in the overall exchange coefficient, the convective heat transfer coefficient, as well as the efficiency and the power of the exchanger. It is noted that an increase of 1% in volume fraction, can enhance the overall exchange coefficient, the power and the effectiveness of the exchanger by 17.62%, 1.473% and 10.80% respectively. Besides, it is noted that the increase in the concentration of nanofluids leads to a narrowing of the pinch points of the inlet and outlet temperatures, which means that nanofluids are more efficient in cooling temperatures than conventional fluids.

Published: January 2021

ABSTRACT (248 WORDS)IntroductionThere is public concern about potential associations between adolescent social media/smartphone use and risk for suicide. However, no prior studies leverage qualitative methods to explore the experiences of adolescents currently at‐risk for suicide.MethodsThis study examined social technology use from the perspectives of adolescents (n = 30; Mage = 16.1 years) currently hospitalized for a recent suicide attempt or severe ideation. We conducted in‐depth interviews and coded transcripts using thematic analysis. We had three research questions: What (1) negative and (2) positive experiences do suicidal adolescents report related to their use of social media/smartphones? (3) How do adolescents describe their disconnection from these technologies use during inpatient hospitalization and views on a subsequent return to digital connectivity after discharge?Results and conclusionsResults reveal both positive and negative social technology uses, with most participants reporting mixed (positive and negative) experiences. Negatives/risks included trouble regulating use, stress related to social media metrics, encounters with “triggering” content, hostility and meanness, self‐denigrating comparisons, and burdensome friendship expectations. Positives/benefits included social connection, social support, affect‐enhancing content, shared interests, and resources for mental health and coping. Overall, the documented risks and benefits of social technology use correspond with established (offline) risk and protective factors for suicidal thoughts and behaviors. Participants generally valued the break from social technologies during hospitalization, and also viewed them as integral to social re‐entry and identified related concerns. Future studies should test well‐being focused ‘digital hygiene’ interventions for maximizing potential benefits and minimizing potential harms of social technologies for at‐risk adolescents.

AbstractA crossover trial was conducted to compare hand rub and hand scrub-brush methods for reducing bacterial loads when using propan-1-ol-60% according to European regulations. Both methods significantly reduced the bacterial load immediately after antisepsis, but only the hand rub method achieved significant bacterial load reduction 3 hours after the procedure.
Dangerous dyads in the post-Soviet space: explaining Russia's military escalation decisions, 1992–2010
Authors: Rosa Paolo , Cuppuleri Adriana 
Published: January 2021

AbstractThis paper analyses the military behaviour of Russia from 1992 to 2010. The method used is a combination of the dyad analysis introduced by Stuart Bremer in 1992 and the analysis of unit-level variables, which is distinctive of foreign policy analysis. We empirically test a set of hypotheses about the determinants of Russia's military behaviour in the post-Cold War period by considering the impact of changes of international variables – relative power, the presence of military alliance pacts, the territorial salience of the dispute – and state-level variables – the degree of democracy/autocracy and regime vulnerability. A bivariate and a multivariate analysis are carried out to explain the separate and joint impacts of independent variables.
Standardised ginseng extract G115® potentiates the antidepressant-like properties of fluoxetine in the forced swim test
Authors: Terstege Dylan J. , MacDonald Debra S. , Tasker R. Andrew 
Published: January 2021

AbstractObjective:Ginsenosides, biologically active components of the root ofPanax ginseng, have been reported to have therapeutic benefits in a number of disease states including psychiatric conditions such as major depressive disorder. Our objective was to determine if a standardised commercial ginseng extract, G115®, could reduce the signs of behavioural despair commonly observed in animal models of depression either alone or in combination with the selective serotonin reuptake inhibitor (SSRI) fluoxetine.Methods:Male Sprague-Dawley (SD) rats (N = 51) were divided into four groups: vehicle control, G115® ginseng root extract, fluoxetine and fluoxetine plus G115®. Rats were trained to voluntarily consume treatments twice daily for 14 days and were then tested in an open field (OF), elevated plus maze (EPM) and forced swim test (FST). Post-mortem hippocampal and prefrontal cortex tissue was analysed for expression of brain-derived neurotrophic factor (BDNF) and tropomyosin receptor kinase B (TrkB) by western blot.Results:One-way Analysis of Variance revealed no significant group differences in the OF or plus-maze performance on any variable examined. In the FST, fluoxetine significantly reduced immobility time and increased latency to immobility. The effects of fluoxetine were further significantly potentiated by co-administration of G115®. Post-mortem tissue analysis revealed significant group differences in BDNF expression in the left hippocampus and left prefrontal cortex without any accompanying changes in TrkB expression.Conclusions:We conclude that oral G115® significantly potentiates the antidepressant-like effect of fluoxetine in the FST in the absence of potentially confounding effects on locomotion and anxiety.

AbstractObjectiveThe ENT run through pilot was introduced in 2018 to improve early recruitment to the specialty. This study aimed to understand what makes a successful interview applicant and the experience of the run through trainees during the specialty trainee one and specialty trainee two years.MethodA questionnaire survey was sent to all ENT run through trainees.ResultsTwenty-three trainees responded. Of the successful candidates, 74 per cent held additional degrees prior to application. The median core surgical interview rank was 27 (range: 3–174). Trainees felt that being on the run through pilot had increased ENT trainer engagement.ConclusionThe ENT run through posts are highly competitive, and holding an additional degree may improve applicant success. The pilot programme has been successful by increasing trainer engagement at this critical stage of training. These results will enable development of the pilot programme and provide valuable information for those applying to an ENT run through post.
