Clinical examinations for medical students during the COVID-19 outbreak: a simulated patient programme perspective
Authors: Ngiam Nicola , Yasol Geena , Goh Denise Li-Meng 
Published: October 2020

BackgroundThe COVID-19 pandemic had a profound impact on how our university had to administer the high stakes, final year medical undergraduate clinical examinations without real patients, while maintaining its validity and rigour.Method11 out of the 21 stations of the medical, surgical and orthopaedic clinical examinations needed to be converted to simulated patient (SP)-based or task-based stations. Cases were developed based on an assessment blueprint, with consideration for SP demographics and availability of equipment. Infection control measures were strictly enforced to avoid transmission of COVID-19. Planning had to include consideration for physical distancing, cohorting and segregation of students and examiners. Student and SP anxiety had to be addressed.ResultsThe examination was executed successfully for 300 medical students. Everyone worked professionally and dealt with the changes and precautions that were required with flexibility.DiscussionAn infectious disease outbreak can derail plans for major clinical examinations. Factors that facilitated a rapid and effective response included decisive leadership, open communication, willingness to collaborate, mobilising resources, adaptability and flexibility. Our school managed uncertainty by erring on the side of caution. This experience may serve as a reference for others in similar situations, particularly when COVID-19 restrictions start to be lifted.

BackgroundAlthough stroke management, primary and secondary preventions have been improved in China last decades, the trends and predictors of major vascular events after ischaemic stroke or transient ischaemic attack (TIA) at national scale are less known.MethodsData were obtained from the three phases of China National Stroke Registry (CNSR), including CNSR-Ⅰ (years 2007–2008), CNSR-Ⅱ (years 2012–2013) and CNSR-III (years 2015–2018). For comparison, patients who were diagnosed as ischaemic stroke or TIA were included. Kaplan-Meier estimates of myocardial infarction (MI) or vascular death were calculated at 1 year. Independent predictors were further assessed with a Cox proportional hazards regression.ResultsFrom 2007 to 2018, a total of 50 284 patients with ischaemic stroke or TIA were enrolled in this study. A declining trend was found in 1-year MI or vascular death (p for trend <0.001), while recurrent stroke depicted a U-shape curve with a nadir in 2012–2013 cohort. A similar trend was also observed in patients who were admitted to 26 hospitals in all three CNSRs. In 2015–2018 cohort, only 251 (1.7%; 95% CI 1.5% to 1.9%) MI or vascular death had occurred at 1 year. Older age, previous stroke or TIA, history of coronary artery disease and the National Institutes of Health Stroke Scale >6 were associated with both an increased risk of MI or vascular death and recurrent stroke. While early antiplatelet therapy and lipid-lowering agents at discharge predicted a reduced risk.ConclusionA declining trend and current low incidence of MI or vascular death, rather than recurrent stroke, after ischaemic stroke or TIA were observed in China. Traditional factors were found as independent predictors. These findings suggested there is still much room to improve for stroke management.
Data-Driven Analysis of Tiny Touchscreen Performance with MicroJam
Authors: Martin Charles Patrick , Torresen Jim 
Published: October 2020

Abstract
The widespread adoption of mobile devices, such as smartphones and tablets, has made touchscreens a common interface for musical performance. Although new mobile music instruments have been investigated from design and user experience perspectives, there has been little examination of the performers' musical output. In this work, we introduce a constrained touchscreen performance app, MicroJam, designed to enable collaboration between performers, and engage in a data-driven analysis of more than 1,600 performances using the app. MicroJam constrains performances to five seconds, and emphasizes frequent and casual music-making through a social media–inspired interface. Performers collaborate by replying to performances, adding new musical layers that are played back at the same time. Our analysis shows that users tend to focus on the center and diagonals of the touchscreen area, and that they tend to swirl or swipe rather than tap. We also observe that, whereas long swipes dominate the visual appearance of performances, the majority of interactions are short with limited expressive possibilities. Our findings enhance our understanding of how users perform in touchscreen apps and could be applied in future app designs for social musical interaction.
The Reflection Effect for Higher-Order Risk Preferences
Authors: Bleichrodt Han , Bruggen Paul van 
Published: October 2020

Abstract
Higher-order risk preferences are important determinants of economic behavior. We apply insights from behavioral economics: we measure higher-order risk preferences for pure gains and losses. We find a reflection effect not only for second-order risk preferences, as did Kahneman and Tversky (1979), but also for higher-order risk preferences: we find risk aversion, prudence and intemperance for gains and much more risk-loving preferences, imprudence and temperance for losses. These findings are at odds with a universal preference for combining good with bad or good with good, which previous results suggest may underlie higher-order risk preferences.
Victim Incentives and Criminal Activity: Evidence from Bus Driver Robberies in Chile
Authors: Dominguez Patricio 
Published: October 2020

Abstract
This paper analyzes crime as a function of the interaction between offenders and victims. I study robbery of bus drivers, a crime that remains common in cities throughout the world. Exploiting the timing of a Chilean public transportation reform and detailed administrative data, I show how victims' propensity to resist an attack can alter the level and nature of criminal activity. I also find a large decline in crime after the implementation of a technological innovation that eliminated cash transactions on buses. My results suggest a strong relationship between victim incentives, cash, and crime.
Description of Ektaphelenchus masseyi n. sp. (Rhabditida: Ektaphelenchinae) found in dead wood, from Iran
Authors: Heydari Fariba , Pedram Majid 
Published: October 2020

Summary
Ektaphelenchus masseyi n. sp. is described and illustrated. The new species was isolated from dead/rotten wood collected from natural forests in north Iran. It is characterised by 501-758 μm long females having three lines in lateral field, more or less continuous cephalic region separated from the body only by a shallow depression, relatively short tripartite stylet (total length 13-14 μm) lacking basal knobs or swellings, excretory pore at base of metacorpus or slightly anterior to it, post-vulval uterine sac 24-32 μm long, rectum and anus absent, posterior body region conical with finely rounded terminus, and males rare, with a dorsally convex and ventrally flat tail with a small mucron at terminus, 13-15 μm long spicules, and seven caudal papillae. The new species was morphologically compared with typologically similar species of Ektaphelenchus having three lines in the lateral field, namely E. joyceae, E. macrobulbosus, E. taiwanensis, and E. winteri. It was further compared with E. olitorius and E. prolobos having a similar female posterior body end shape and with an unknown number of incisures in the lateral field. It was also compared with three species currently placed under Ektaphelenchoides, namely E. andrassyi and E. poinari with three lines in the lateral field, and E. compsi with obscure lateral lines. The molecular phylogenetic relationships of the new species with other ektaphelenchid species were investigated using partial small, and large subunit ribosomal RNA gene (SSU and LSU rDNA D2-D3) sequences using the maximal number of currently sequenced ektaphelenchid and seinurid taxa.
Russia as the State Continuing the Legal Personality of the USSR – An Inquiry into State Identity or Succession
Authors: Acquaviva Guido 
Published: October 2020

Abstract
The Russian Federation is overwhelmingly considered the same subject of international law as the USSR. Moving from a re-assessment of the incidence of the elements traditionally associated with the identity of a state, this article notes that scholars have generally neglected to study what are the actual bases for this nearly universal consensus. Since the creation and the identity of states are often described as questions of fact, the author suggests that a useful addition to the debate surrounding the identity of the USSR and Russia is an analysis of the nature of the actual governmental power within the USSR. This may contribute to assessing anew how the seismic changes in 1990 and 1991 affected it and, therefore, how contemporary Russia actually arose. Such an interdisciplinary approach to the question of state succession could further be used to shed light on similar cases of succession.
Manufacturing International Law: Pre-printed Treaties in the ‘Scramble for Africa’
Authors: Harris Steven M. 
Published: October 2020

Abstract
The 1880s saw a unique confluence of means, motives, and opportunities which led the British and their agents on African frontiers to enter into hundreds of pre-printed form treaties with local groups. By treating indigenous groups as interchangeable counterparties to their agreements, the new tools carried by these diplomats in canoes carried both the benefits of expediency and the problems of alienation. The mass production of international law – made by relatively unskilled labour, in bulk, with limited variation – had arrived. This practice connects the emerging modernity of the cultures of international law, diplomacy, printing technology, and domestic law.
Theorising Order in the Shadow of War. The Politics of International Legal Knowledge and the Justification of Force in Modernity
Authors: Simon Hendrik 
Published: October 2020

Abstract
The History of International Law lacks systematic studies on the link between legal scholars and practices of justifying war. This missing analytical link has for a long time given the impression that legal scholars describe ‘state practice’ in an ‘objective’, unpolitical way. Contradicting this impression, the article turns to the politics of legal scholars in the genesis of the modern war discourse. It reflects on the fateful entanglement of violence, law and politics, but nevertheless distinguishes between ‘objective’ and ‘political’ scholarship on the basis of Hans Kelsen’s work. Furthermore, the article illustrates the politicisability of legal scholars in selected historical cases of the ‘long 19th century’ (1789–1918). In all cases, two hearts pounded in lawyers’ chests: one scientific, the other political. As will be shown, the modern war discourse is shaped by a phenomenon that enables scholars to expand the intrinsic limits to the political instrumentalisation of law: ‘multi-normativity’.
The Challenges of Registration of Asylum-Seekers in the Hashemite Kingdom of Jordan
Authors: al-Arasi Sarah Mahmoud , al-Afaishat Muneer Mohammad Shahada , al-Tibi Tareq Majed 
Published: October 2020

Abstract
This study aims to identify difficulties and challenges facing countries without a National Registration Law, with the Hashemite Kingdom of Jordan as model. Jordan, in compliance with the United Nations High Commissioner for Refugees (UNHCR), regulates the presence of refugees and asylum seekers inside the Kingdom and at its borders in accordance with the UNHCR 1998 Memorandum of Understanding. Many such individuals have lost their identification documents when forced to leave their homelands due to armed conflict. Jordanian authorities try to solve such problems through the use of a magnetic-card system and iris scans. This study concludes that Jordan, in ratio to its population, is the second country worldwide to host the largest number of refugees. This study recommends that Jordan enact a National Asylum Law to regulate the presence of such refugees in the Kingdom.
Sharīʿah Regulation and Supervision of the Iraqi Islamic Banking System
Authors: Salh Shamsalden Aziz , Hyland Mark 
Published: October 2020

Abstract
This article critically evaluates the Sharīʿah regulation and supervision of the Iraqi Islamic banking system. Due to the country’s incomplete Islamic banking framework and lack of qualified Sharīʿah scholars, the Iraqi Islamic banking system is somewhat ineffective. In Iraq both the internal and external Sharīʿah supervisory systems in the Islamic banking sector are weak. The internal Sharīʿah supervisory system suffers from a shortage of qualified Islamic banking experts. At the same time, there is no effective external Sharīʿah supervisory system due to the lack of a Central Sharīʿah Board. This article examines the Sharīʿah supervisory system of the Iraqi Islamic banking industry by using case studies on Malaysia and Bahrain, both of which have a developed Islamic banking system. The Sharīʿah supervisory systems in these two countries are examined in order to propose an effective and comprehensive Sharīʿah regulatory and supervisory framework for the Iraqi Islamic banking industry.
Small Business Bankruptcy Reform in the Arab World: Two Steps Forward, One Step Back
Authors: Kilborn Jason J. 
Published: October 2020

Abstract
This article assesses a series of recently adopted bankruptcy laws in the Arab world, situating them within three historical phases of global bankruptcy reform. It introduces recently released recommendations from international standard-setting organisations for best practices in the bankruptcies of small and medium enterprises (SME) and applies them to evaluate the key details of recent bankruptcy reforms in Saudi Arabia, the United Arab Emirates, Egypt, Morocco, Tunisia, Oman, and Bahrain. Seeking an explanation for the persistent absence of an especially crucial element of effective SME rescue policy, it recalls the Islamic law relating to debt distress and recovery. Finally, it reveals a revolutionary new approach to this controversial topic, adopted by one Arab state to produce a bankruptcy law that is truly and exceptionally responsive to the needs of SME s.
Different Structure, Neither Debt nor Equity: What Should Be the Approaches for Restructuring Ṣukūk (Islamic Bonds) Default?
Authors: Radzi Rafisah Mat 
Published: October 2020

Abstract
This study discusses the issues of ṣukūk (Islamic bonds) default surrounding its transaction structures and potential for restructuring the default. By explaining the basic concept of ṣukūk structure, this study further provides a classification of ṣukūk from the perspectives of the standard-setting bodies and credit-rating agencies. Since the structures that underpin ṣukūk vary and technically ṣukūk is neither debt nor equity, this study provides the potential restructuring of ṣukūk in cases of default. The contingent approaches such as extending maturity, haircut and debt-equity swap are based on the classification of ṣukūk structures and require a case-by-case approach.
Breton non-local spirantization reexamined
Authors: Mondon Jean-François 
Published: October 2020

Abstract
In certain dialects of Breton, spirantization triggered by a few possessive adjectives appears to apply their mutation on a non-local word. A plausible diachronic development is proposed in which noun phrases with and without the intervening word were nearly semantically identical, making it easier for the mutation effects on the noun to spread to the construction in which a word intervened between the possessive adjective and the noun. A synchronic solution couched in Distributed Morphology which makes use of string-vacuous Local Dislocation is proposed, which provides a locality-obeying account.
Refractory Hypocalcemia Following Stomach Intestinal Pylorus-Sparing Bariatric Surgery and Thyroidectomy: Successful Management With Creation of a Proximal Roux-en-Y Gastric Bypass
Authors: Jensen Stephanie M. , Thompson Richard E. , Machineni Sriram , Overby David W. , Farrell Timothy M. 
Published: October 2020

Some forms of bariatric surgery make patients susceptible to calcium malabsorption, and the parathyroid hormone (PTH) axis is important for maintaining normocalcemia in these patients. Injury to the parathyroid glands due to anterior neck surgery commonly causes PTH axis disruption and can result in severe hypocalcemia in bariatric surgery patients. Herein, we present a case of a patient with a history of stomach intestinal pylorus-sparing bariatric surgery who developed refractory hypocalcemia requiring daily intravenous (IV) calcium 2 years after thyroidectomy. PTH levels were inappropriately normal during episodes of hypocalcemia, and urinary calcium level was <3.0 mg/dL following large oral doses of calcium, suggesting that both inadequate PTH response and malabsorption contributed to her severe hypocalcemia. In order to enhance calcium absorptive capacity while minimizing the risk of weight regain, she was surgically treated with a Roux-en-Y gastric bypass proximal to the prior operation. The surgery successfully improved blood calcium levels; the patient was successfully weaned from IV calcium and was able to maintain normocalcemia with oral supplements. We discuss the case in the context of available literature and provide our recommendations.

Background Multisite studies can considerably increase the pool of normally aging individuals with neurodegenerative disorders and thereby expedite the associated research. Understanding the reproducibility of the parameters of related brain structures—including the hippocampus, amygdala, and entorhinal cortex—in multisite studies is crucial in determining the impact of healthy aging or neurodegenerative diseases. Purpose To estimate the reproducibility of the fascinating structures by automatic (FreeSurfer) and manual segmentation methods in a well-controlled multisite dataset. Material and Methods Three traveling individuals were scanned at 10 sites, which were equipped with the same equipment (3T Prisma Siemens). They used the same scan protocol (two inversion-contrast magnetization-prepared rapid gradient echo sequences) and operators. Validity coefficients (intraclass correlations coefficient [ICC]) and spatial overlap measures (Dice Similarity Coefficient [DSC]) were used to estimate the reproducibility of multisite data. Results ICC and DSC values varied substantially among structures and segmentation methods, and values of manual tracing were relatively higher than the automated method. ICC and DSC values of structural parameters were greater than 0.80 and 0.60 across sites, as determined by manual tracing. Low reproducibility was observed in the amygdala parameters by automatic segmentation method (ICC = 0.349–0.529, DSC = 0.380–0.873). However, ICC and DSC scores of the hippocampus were higher than 0.60 and 0.65 by two segmentation methods. Conclusion This study suggests that a well-controlled multisite study could provide a reliable MRI dataset. Manual tracing of volume assessments is recommended for low reproducibility structures that require high levels of precision in multisite studies.
Serum microRNA-365 suppresses non-small-cell lung cancer metastasis and invasion in patients with bone metastasis of lung cancer
Authors: Liu Yanyan , Jia Junmei , Song Bin , Qiu Haile , Liang Gang , Zhang Bo , Wang Kang 
Published: October 2020

Objective In the present investigation, we evaluated the effects of microRNA-365 (miR-365) on non-small-cell lung cancer (NSCLC) cell metastasis and invasion in patients with bone metastasis of lung cancer. Methods Blood samples from patients with NSCLC and healthy controls and the A549 adenocarcinoma cell line were included in this study. Quantitative real-time PCR and microarray were performed on blood samples. The MTT assay, luciferase reporter assay, Transwell assay, ELISA, and western blot were performed to evaluate expression of associated factors. Results Expression of miR-365 was reduced in patients with bone metastasis of NSCLC. Downregulation of miR-365 promoted cell growth, metastasis, and invasion of NSCLC. Upregulation of miR-365 reduced cell growth, metastasis, and invasion of NSCLC. Downregulation of miR-365 induced expression of NKX homeobox-1 (NKX2-1), epidermal growth factor receptor (EGFR), phosphoinositide-3-kinase (PI3K), and p-Akt proteins in an in vitro model of NSCLC. Inhibition of NKX2-1 reduced the effects of miR-365 on cell growth, metastasis, and invasion of NSCLC. Activation of EGFR reduced the effects of miR-365 on cell growth, metastasis, and invasion of NSCLC. Conclusions The study established that the serum miR-365 suppresses NSCLC cell metastasis and invasion in patients with bone metastasis of lung cancer via EGFR/PI3K through NKX2-1.
Contact lens induced bacterial keratitis in LCD II: Management and multimodal imaging: a case report and review of literature
Authors: Alafaleq Munirah , Knoeri Juliette , Boutboul Sandrine , Borderie Vincent 
Published: October 2020

Purpose: To describe the management and multimodal imaging of lattice corneal dystrophy type II (LCD-II) complicated by an infectious keratitis due to a bandage contact lens and to review current literature. Observation: A 50-year-old female was diagnosed with Meretoja’s Syndrome by the triad of facial palsy, loose skin (cutix laxa), and stromal corneal dystrophy. At slit lamp, bilateral lattice corneal dystrophy (LCD) was characterized by multiple linear refractile lines and subepithelial fibrosis along with Neurotrophic keratitis Mackie grade I. Findings of anterior segment optical coherence tomography (AS-OCT) were epithelial irregularity, subepithelial fibrosis, hyperreflectivity on anterior stromal layer, lobulated stromal surface. In vivo confocal microscopy (IVCM) showed hyperreflected deposits on the basal and Bowman layers, visible keratocytes; fine lines and streaks between corneal lamella. The sub-basal nerve plexus and the stromal nerves were no longer visible. She presented in emergency with a left red eye. A severe bacterial keratitis was diagnosed as a complication of a bandage contact lens used to treat recurrent epithelial erosion. Corneal anesthesia was complete. Corneal neovascularization was evident 10 weeks later and topical bevacizumab (5 mg/ml) was introduced twice daily. Partial regression of deep stromal vessels was noticed at 3 months. Conclusion: In Meretoja’s syndrome, neurotrophic keratopathy secondary to polyneuropathy due to systemic amyloid deposits is present in the advanced stages, promotes recurrent corneal erosions. Corneal sensitivity test, AS-OCT and IVCM are crucial in the diagnosis behind any recurrent corneal erosion. The use of bandage contact lens should be avoided in Meretoja’s syndrome to prevent a possible infectious keratitis.
