Acute inflammatory demyelinating polyneuropathy or Guillain-Barré syndrome associated with COVID-19: a case report
Authors: Gagarkin Dmitriy A. , Dombrowski Keith E. , Thakar Keyur B. , DePetrillo John C.
Published: April 2021

Background

Coronavirus disease 2019 (COVID-19) is a global pandemic. The disease, typically characterized by bilateral pulmonary infiltrates and profound elevation of inflammatory markers, can range in severity from mild or asymptomatic illness to a lethal cytokine storm and respiratory failure. A number of recognized complications of COVID-19 infection are described in the literature. Common neurological complications include headache and anosmia. Guillain-Barré syndrome (GBS) is an uncommon complication described in isolated case reports. However, a causal relationship has yet to be established. This case report adds to the growing body of evidence that GBS is a potential COVID-19 complication.

Case presentation

A 70-year-old Caucasian woman with recently diagnosed COVID-19 infection presented to the emergency department with 4 days of gradually worsening ascending lower extremity weakness. Exam revealed bilateral lower extremity weakness, mute reflexes, and sensory loss. Soon after starting intravenous administration of immunoglobulin (IVIG), the patient developed respiratory distress, eventually requiring intubation. She remained intubated for the duration of her IVIG treatment. After five rounds of treatment, the patient was successfully extubated and transferred to acute rehab. Following 4 weeks of intense physical therapy, she was able to walk with assistance on room air.

Conclusion

At the present time, this is one of the few reports of acute inflammatory demyelinating polyneuropathy (AIDP) or GBS associated with COVID-19 in the United States. It is unclear whether a causal relationship exists given the nature of the syndrome. However, in light of the growing number of reported cases, physicians should be aware of this possible complication when evaluating COVID-19 patients.
Is T2 mapping reliable in evaluation of native and repair cartilage tissue of the knee?
Authors: Banitalebi Hasan , Owesen Christian , Årøen Asbjørn , Tran Hang Thi , Myklebust Tor Åge , Randsborg Per-Henrik
Published: April 2021

Purpose

To evaluate the effect of imaging plane and experience of observers on the reliability of T2 mapping of native and repair cartilage tissue of the knee.

Methods

Fifteen consecutive patients from two randomised controlled trials (RCTs) were included in this cross-sectional study. Patients with an isolated knee cartilage lesion were randomised to receive either debridement or microfracture (RCT 1) or debridement or autologous chondrocyte implantation (RCT 2). T2 mapping was performed in coronal and sagittal planes two years postoperatively. A musculoskeletal radiologist, a resident of radiology and two orthopaedic surgeons measured the T2 values independently. Intraclass Correlation Coefficient (ICC) with 95% Confidence Intervals was used to calculate the inter- and intraobserver agreement.

Results

Mean age for the patients was 36.8 ± 11 years, 8 (53%) were men. The overall interobserver agreement varied from poor to good with ICCs in the range of 0.27– 0.76 for native cartilage and 0.00 – 0.90 for repair tissue. The lowest agreement was achieved for evaluations of repair cartilage tissue. The estimated ICCs suggested higher inter- and intraobserver agreement for radiologists. On medial femoral condyles, T2 values were higher for native cartilage on coronal images (p < 0.001) and for repair tissue on sagittal images (p < 0.001).

Conclusions

The reliability of T2 mapping of articular cartilage is influenced by the imaging plane and the experience of the observers. This influence may be more profound for repair cartilage tissue. This is important to consider when using T2 mapping to measure outcomes after cartilage repair surgery.

Preventing crash in stock market: The role of economic policy uncertainty during COVID-19
Authors: Dai Peng-Fei , Xiong Xiong , Liu Zhifeng , Huynh Toan Luu Duc , Sun Jianjun
Published: April 2021

This paper investigates the impact of economic policy uncertainty (EPU) on the crash risk of US stock market during the COVID-19 pandemic. To this end, we use the GARCH-S (GARCH with skewness) model to estimate daily skewness as a proxy for the stock market crash risk. The empirical results show the significantly negative correlation between EPU and stock market crash risk, indicating the aggravation of EPU increase the crash risk. Moreover, the negative correlation gets stronger after the global COVID-19 outbreak, which shows the crash risk of the US stock market will be more affected by EPU during the epidemic.
Primary breast angiosarcoma: a case report
Authors: Pang Fui Tin , Lee Sze Yuen , Kaur Maninderpal
Published: April 2021

Background

Angiosarcomas are rare and fast growing tumors that arise from vascular structures. This case report is significant because it is rare and may cause treatment delay if not considered as a differential diagnosis. Hence, we aim to inform efficient, appropriate, and evidence-based imaging practice to the benefit of patients regionally and worldwide.

Case presentation

Thirty-five-year-old lady, presented with a large left breast swelling. She had recent history of trauma to the breast which initially caused confusion regarding the possible diagnosis. Ultrasound and MRI raised high suspicion of an angiosarcoma. Patient went through embolectomy prior to mastectomy and axillary clearance. Histopathology confirmed the diagnosis of an angiosarcoma. She had no distant metastases at the time of diagnosis and the patient was treated with chemotherapy and radiotherapy. However, she returned with recurrence within 1-year duration.

Conclusion

Primary breast angiosarcomas are rare aggressive vascular tumors with generally poor prognosis and no pathognomonic signs on radiological imaging, especially mammogram. Ultrasound and MRI do help in characterizing these tumors and raising the suspicion of a vascular tumor. Ultrasound-guided biopsy is recommended to avoid unnecessary complications. In young patients with rapidly growing, highly vascular breast tumors, a differential diagnosis of primary angiosarcomas should be considered until proven otherwise.
Impact of financing decisions ratios on firm accounting-based performance: evidence from Jordan listed companies
Authors: Kasasbeh Feras Izzat
Published: April 2021

The impacts of financing decision ratios on a firm's accounting-based performance are essentially associated with particular data. For this purpose, firm size, firm age, and leverage are taken into account as control variables. The past studies have been reviewed to find gaps, which seemed to incorporate worn-out methods of research, and the inability of past researchers to inculcate firm accounting-based performance while measuring a firm's overall performance. So, data from 40 listed Jordan listed firms from the year 2007 have been collected, and 200 observations are made. The researcher also collected data from the website of the World Bank regarding these firms. It is employed by the generalized movement technique method to avoid heteroscedasticity, autocorrelation, and potential endogenous problems. The study results showed that the impacts of total debt to total assets and short-term debt to total assets are significant and negative on return on assets and return on equity. However, the impacts of long-term debt to total assets are significant and flattering on both return on assets and return on equity. The research has implications for the higher authorities and management to enhance the quality of their financial structure. In contrast, that research has some limitations because of employing a small number of factors to study the impacts of financing decision ratios.
Out of Empire into Socialist Modernity
Authors: Marung Steffi
Published: April 2021

In this article the Soviet-African Modern is presented through an intellectual history of exchanges in a triangular geography, outspreading from Moscow to Paris to Port of Spain and Accra. In this geography, postcolonial conditions in Eastern Europe and Africa became interconnected. This shared postcolonial space extended from the Soviet South to Africa. The glue for the transregional imagination was an engagement with the topos of backwardness. For many of the participants in the debate, the Soviet past was the African present. Focusing on the 1960s and 1970s, three connected perspectives on the relationship between Soviet and African paths to modernity are presented: First, Soviet and Russian scholars interpreting the domestic (post)colonial condition; second, African academics revisiting the Soviet Union as a model for development; and finally, transatlantic intellectuals connecting postcolonial narratives with socialist ones. Drawing on Russian archives, the article furthermore demonstrates that Soviet repositories hold complementary records for African histories.

Uuringu eesmärk on ettevõtlusõpetajate kogemuste analüüsi alusel selgitada, kuidas rakendatakse ettevõtlusõpet Eesti kutsehariduses, keskendudes uurimisküsimusele, kuidas arendatakse ettevõtluspädevust ja rakendatakse  ettevõtluspedagoogikat Eesti kutsehariduses. Teoreetiline lähenemine tugineb sotsiaal-konstruktivistlikest õppimisteooriatest lähtuvale lõimitud pedagoogika lähenemisele ning ettevõtluspädevuse mudelile. Andmestiku moodustavad 26 ettevõtlusõpetajaga tehtud intervjuud, millest osa on tehtud 2018., osa 2019. ja osa 2020. aasta kevadel. Fenomenoloogilise lähenemise raames kasutame induktiivset andmeanalüüsi meetodit. Tulemustest selgub, et ettevõtlusõpe on peamiselt ettevõtlikkuse toetamisele suunatud, sihtrühma spetsiifikat arvestav ja praktiline. Praktilise kogemuse ja eneseregulatiivse teadmise dialoogi puudumine teoreetilisega ning viimase nõrkus on peamised vajakajäämised ettevõtlusõppe pedagoogikas.

Uurimuse eesmärk oli välja selgitada, kuidas seostuvad hilisteismeliste väärtustega tajutud eakaaslaste ja õpetajate hoolivus, aga ka kooli asukoht ja pere sotsiaalmajandusliku staatuse näitajad. Uurimuses osales 528 kümnenda klassi õpilast (keskmine vanus 16,25). Nende väärtusi hinnati Schwartzi portreeküsimustikuga ning tajutud eakaaslaste ja õpetajate hoolivust kahe üksikväitega. Tulemused näitasid, et teismelised väärtustasid enim heasoovlikkust ja hedonismi. Väikelinna koolide õpilastele oli võim vähem oluline ning turvalisus olulisem kui suurlinna koolide õpilastele. Teismelised, kelle emal oli kõrgem haridus, pidasid kõikehaaravust vähem oluliseks kui need, kelle emal oli madalam haridustase. Kui eakaaslaste hoolivus teismeliste väärtustega ei seostunud, siis õpetajate hoolivus seostus enamiku väärtustega. Mida hoolivamatena tajuti õpetajaid, seda kõrgemalt väärtustati teiste inimeste heaolule, looduse hoidmisele ja reeglite järgimisele orienteeritud väärtusi.

DIAGNOSIS OF CHRONIC RADIATION SYNDROME AT THE EARLY STAGE
Authors: Akleev A.
Published: April 2021

Purpose: To describe early symptoms of chronic radiation syndrome (CRS) which is of utmost importance for diagnosing this rare radiation pathology in man.

Material and methods: The paper presents the findings of retrospective analysis of early clinical manifestations of chronic radiation syndrome (CRS) based on the data of a long-term medical follow up of the residents of the Techa riverside communities. Mean doses of postnatal exposure to red bone marrow in patients with CRS calculated with TRDS-2016D were 698.8±18.2 mGy, maximum doses were 3 603.9 mGy.

Results: Clinical picture of the CRS at the early stage was characterized by a set of non-specific changes including hematological, immune, neurological, and endocrine ones, as well as impairment of functions of a number of internal organs. The above-mentioned CRS symptoms developed in a certain sequence and depended on dose rate and absorbed dose to the organs. Prior to the development of a full-scale CRS clinical picture patients had a decrease in olfactory and taste thresholds, in vibration sensitivity, and changes in systemic immunity. Impairment of hematopoiesis, nervous and endocrine systems were also noted even at the early stage of CRS. Initial CRS changes were moderate and transient. The analysis of early CRS symptoms allows assuming that early CRS stage is a dysregulation pathology that is caused initially by radiation-induced disorders of immunohematopoiesis, nervous and endocrine systems. Visceral changes at the early CRS stage are secondary and functional. If exposure is terminated, they are reversible. However, if exposure continues at doses high enough to cause morphological changes in organs and tissues (dystrophy, fibrosis, hypoplasia, etc.), CRS course worsens and becomes irreversible.

Conclusion: It was demonstrated that CRS diagnosis at the early stage is very complicated. The key issue is to analyze the relationship of specific CRS symptoms development and dose rate and absorbed organ doses.

Determinants of Islamic Social Responsibility Disclosure the Case of Islamic Bank: Cross Country Analysis
Authors: Maulana Agus , Violita Evony Silvino
Published: April 2021

Introduction to The Problem: The rapid growth of Islamic financial institutions around the world attracts a lot of attention, but its growing is not supported by adequate accountability. Several evidence show that accountability of Islamic banks is still very low. The lack of accountability may causes low public trust, so it is important to study the determinant of Islamic Social Responsibility Disclosure by Islamic Bank.Objective Study: This study intends to examine the determinants of Islamic Social Responsibility disclosure (ISR). So practitioners and academics can get a clear view of Islamic Bank's accountability through ISR disclosure.Methodology: This paper applies some theories such as stakeholder theories, agency theory, and legitimacy theory to developed hypotheses linking ISR disclosure and its determinants (internationality, Islamic Corporate Governance, and Socio-Political Context). This paper uses the content analysis method to assess the ISR disclosure of Islamic banks from 13 countries spanning from 2014 to 2016. The ISR index consists of 72 items developed based on AAOIFI. Finally, OLS Regression Analysis is used to test the hypotheses.Findings: The paper find that the level of ISR disclosure is still very low (44%). From the internationality aspect, we found that the proportion of foreign ownership and the status of the multinational corporation influenced the level of ISR disclosure, but we did not find evidence that the CEO's overseas experience affected the level of disclosure. This paper also confirm that Islamic Corporate Governance and Socio-Political context are the main determinant of ISR disclosure by Islamic Bank.
Le Deuil d'un pays imaginé : Rêves, luttes et déroute du Canada français
Authors: Martel Marcel
Published: April 2021

Depuis 1960, les relations entre le Québec et la francophonie canadienne n’ont pas cessé de s’effriter. En fait, la Révolution tranquille a apporté dans son sillage le renouvellement du discours identitaire au Canada français. Marcel Martel nous livre ici une fascinante étude historique et politique des rapports entre ces communautés de 1867 à 1975, année précédent l’élection du Parti Québécois. Faisant l’étude de quelques-uns des principaux catalyseurs tels l’Ordre de Jacques-Cartier, le Conseil de la vie française en Amérique, l’Association canadienne-française d’éducation de l’Ontario, le Deuxième Congrès de la langue française et le États généraux du Canada français, il démontre comment le projet de nation canadienne-française s’est transformé au fil des ans. Il identifie aussi les causes qui ont amené les communautés francophones minoritaires à se méfier de l’intervention de l’État québécois.

burning in air at 1 atm. This diagnostic was applied to characterize
how the path-integrated gas temperature of HMX flames varies in time
and with distance above the burning surface. Additionally, Abel
inversion with Tikhonov regularization was applied to determine the

Design method of wide field-of-view imaging systems using Gaussian radial basis functions freeform surfaces
Authors: Ni Junhao , Yang Tong , Cheng Dewen , Wang Yongtian
Published: April 2021

High optical performance systems with wide field-of-view (FOV) have important applications in remote sensing. The radial basis functions, which have a prominent local characteristic in surface description, have attracted much attention in recent years. In this paper, an effective design method for the wide FOV imaging system using Gaussian radial basis function freeform surfaces is proposed. The FOV of the optical system is extended from a relatively small value to a larger one, and the Gaussian radial basis function surfaces are extended stepwise based on certain criteria. A high image quality and small distortion off-axis freeform three-mirror system with a wide FOV (60∘×0.6∘) is designed as an example. Tolerance analysis considering both surface figure error and assembly error is performed. The design results demonstrate the effectiveness of the proposed method.
Numerical investigation of high birefringence and nonlinearity tellurite glass photonic crystal fiber with microstructured core
Authors: Wang Jiangyun
Published: April 2021

In this paper, a novel photonic crystal fiber (PCF) based on tellurite glass with high birefringence and high nonlinearity is designed. Six small air holes arranged nearly rectangularly are added in the fiber core to form the near-elliptic core. By using the finite-element method with the help of COMSOL Multiphysics software, we investigate and simulate the birefringence, effective mode area, nonlinear coefficient, and the dispersion characteristics. Simulation results show that by optimizing the structure parameters of the core, at the wavelength of 1.55 µm, the birefringence is up to

Fast processing of underwater polarization imaging based on optical correlation
Authors: Zhang Huajun , Ren Mingyuan , Wang Hantao , Yao Jinren , Zhang Yu
Published: April 2021

Underwater polarization differential imaging requires the estimation of different parameters, and the parameters can be accurately obtained by using optical correlation. However, optical correlation as a criterion function to estimate parameters takes a lot of time. To expedite the parameters’ estimation process, we propose two operations to process underwater polarization images. One operation is to update the analyzer angle range to reduce the number of processed images. The other is image downsampling, which reduces the amount of calculation for the corresponding images. In experiments, we confirmed the feasibility of our method. We have obtained an average of 42 times the calculation speed increase under the conditions of updating the analyzer angle range 3 times and reducing the image scale by 16 times. The results of our method are consistent with those of traditional methods. This established method is conducive to the practical application of underwater polarization differential imaging.
