Published: November 2021

Intramedullary spinal cord tumors are rare and comprise less than one percentage of all central nervous system (CNS) neoplasms. When encountered, most are found in the lumbosacral region with coinciding spinal dysraphism. Here, we discuss a case of isolated non-dysraphic intramedullary lipoma of cervicothoracic spine in an adolescent who was surgically managed with posterior decompression and subtotal resection via laminoplasty.
A 21-year-old male adolescent, without a history of spinal dysraphism, presented with a progressive sensory ataxia. This manifestation was attributed to magnetic resonance documented intramedullary lipoma, extending from C7 to T2 spinal level. Patient underwent subtotal surgical resection of the lesion; and histopathology report was confirmed as spinal lipoma.
Surgical management of this rare pathology has a wide variety of options depending on clinical presentation. In our case, a subtotal resection and laminoplasty was achieved with no further worsening of neurologic symptoms.

Published: November 2021

Introduction: Traumatic brain injury disease of major importance globally. Prognostic models are useful for making decisions in the clinical practice. The aim of this study was to assess the accuracy of International Mission for Prognosis and Analysis of Clinical Trials in TBI (IMPACT) score in predicting outcome in moderate to severe TBI at 3 months. 
Materials and Methods: All patients admitted to National Trauma Center, National Academy of Medical Sciences with moderate to severe traumatic brain injury from February 2020 to February 2021 were included in the study. IMPACT scores (core/extended core/ lab) were recorded separately at admission. Outcome was measured with Glasgow Outcome Scale (GOS) at the time of discharge and at six months. Correlation between observed and predicted outcomes was evaluated by Pearson’s correlation coefficient (r). Sensitivity and specificity were plotted in the receiver-operating characteristic (ROC) curve, and the area under the curve (AUC) was calculated to determine the discrimination ability of this prognostic model.
Results: A total of 112 patients were enrolled in the study. Eighty (71.4 %) patients had moderate and 32 (28.57 %) had severe TBI. The median age was 33 years with male preponderance (M: F=4:1). Thirty three (29.5 %) patients died within 6 months of TBI, and 38 (33.9 %) patients  had an unfavorable outcome. Pearson correlation coefficient showed good correlation between observed and predicted outcomes. Hosmer-Lemeshow test showed good model fit for IMPACT core, IMPACT extended and IMPACT lab in diagnosing mortality and unfavorable outcome in six months (p>0.05). The ROC curve indicated that all 3 models could accurately discriminate between favorable and unfavorable outcomes, as well as between survival and mortality (unfavorable outcome AUC= 0.905, 0.940, 0.955; mortality AUC= 0.875, 0.914, 0.917 respectively) in our patient population.
Conclusion: The IMPACT score is a good prognostic model to predict 6-month outcomes in moderate to severe TBI at admission in Nepalese patient population. Among the three IMPACT models, IMPACT lab has the greatest discriminating ability.

Portfolios with Evidence of Reflective Practice Required by Regulatory Bodies: An Integrative Review
Authors: Zaccagnini Marco , Miller Patricia A.
Published: November 2021

Purpose: Regulatory bodies impose continuing professional development (CPD) requirements on health care professionals (HCPs) as a condition for license revalidation. Many regulatory bodies require annual evidence of CPD activities that are informed by reflective practices, guided by learning plans, and compiled into a portfolio. The purpose of this integrative review is to summarize the literature discussing how regulatory bodies use portfolios with evidence of reflection for licensure renewal. Method: We reviewed English-language articles published until May 2020 discussing evidence of CPD and reflective practice in portfolios in the context of licensure renewal. Results: We located 17 articles for the review. None reported or measured outcomes beyond submission of reflective evidence. Sixteen articles (93%) included information about passive learning resources that regulatory bodies provided to help guide HCPs’ reflective learning activities. HCPs’ feedback about using reflective learning activities indicated mixed opinions about their utility. Conclusions: Few publications reported how jurisdictions expected HCPs to provide evidence of reflective practices for licensure renewal. None of the regulatory bodies required evidence regarding the impact of reflective practice on patient or organizational outcomes. HCPs reported both benefits and challenges of a mandated reflective process.
‘My mother left behind a few manuscripts.’ On the author’s perspective of L. Petrushevskaya
Authors: Gordon T. A. , Rafalson N. S.
Published: November 2021

The genre-speciﬁc nature of L. Petrushevskaya’s The Time: Night [Vremya noch] and its intertextual aspect are examined in the context of ideas about the folk character of art. The paper especially focuses on drawing parallels with A.Akhmatova’s works. The authors pose a question: how does the story interpret the topic that is paramount for Russian literature — public consciousness? Petrushevskaya’s works typically evoke the drama of antiquity, Russian folklore and the Narodnichestvo ideology. Her prose brings back the images of the classical tragedy (fate, retribution, the chorus), common Russian folk mythologemes (an orphaned child, a frisky steed, and sister Alyonushka), as well as Pochvenniks’ theses about popular wisdom. The article suggests that The Time: Night both subverts and pays homage to it. The novelet parodies but also celebrates folk epos and its creators.
D. Portnova. The dotted line of distant joys
Authors: Duardovich I.
Published: November 2021

The review deals with a book of reminiscences by Dalila Portnova, a niece of the writer Yury Dombrovsky (1909–1978), a preeminent master of prison camp prose who wrote extensively about Stalin-era repressions. The chapters devoted to the author’s family include Portnova’s memories of her late uncle that were ﬁrst printed in the Noviy Mir journal in 2017; a sensation at the time, they also provoked a mixed reaction of surviving family members and people who knew Dombrovsky well. Yet no coherent attempts were made to disprove the publication (other than comments on Facebook), even though Portnova’s account is not without flaws and inaccuracies. In his review, Igor Duardovich points out the valid new facts recounted in Portnova’s memoir as well as its discrepancies and explains why the book is relevant for a complete reconstruction of Dombrovsky’s biography: a project as yet unaccomplished, either in the form of separate publications or as a monograph.

Published: November 2021

By simulating the welding process, potential non-conformities can be detected before serial production is launched, which can significantly reduce operation costs. There are many different possibilities for modeling the process, therefore it is very important to choose a method that will ensure high accuracy of the solution in a relatively short time. The article will present the influence of various methods of modeling the welding process in the CAE environment on the obtained deformation results. For the given geometry and type of weld, the thermal deformations have been simulated based on the Finite Element Method. Several analyzes were carried out using different process modeling approaches (mesh type). Finally, a comparison of the results for the discussed cases is presented to determine the influence of the parameters used on the deformation results obtained.
Adapt to Translate
Authors: Jadreškić Daria
Published: November 2021

The article presents the advantages and limitations of adaptive clinical trials for assessing the effectiveness of medical interventions and specifies the conditions that contributed to their development and implementation in clinical practice. I advance two arguments by discussing different cases of adaptive trials. The normative argument is that responsible adaptation should be taken seriously as a new way of doing clinical research insofar as a valid justification, sufficient understanding, and adequate operational conditions are provided. The second argument is historical. The development of adaptive trials can be related to lessons learned from research in cases of urgency and to the decades-long efforts to end the productivity crisis of pharmaceutical research, which led to the emergence of translational, personalized, and, recently, precision medicine movements.

Published: November 2021

It is necessary to recognize and address the differential impact of disasters on society. It is quite possible that a significant number of children to become victims of the COVID-19 caused social disaster. As a result, there would be an increase in the number of school dropouts and child labor, which indicates a substantial number of children will be deprived of their right to education. Any alternative response during school closure, like internet-based remote teaching learning, might not compensate the loss of learning as nearly half of the world is without access to the internet. "Emergency situations" are considered any situation either man-made or natural disasters suddenly disrupt the normal course of life, empathy and educational opportunities of children. The present study intended to find out the nature of social disaster caused by COVID-19 and how it impacted the learning loss and socio-emotional immunity of the under privileged school going children. A narrative review technique was used for this research study to explore the policy advocacies adopted in emergency basis in mitigating the impacts of the ongoing pandemic on such underprivileged children.  The data were derived from published articles and reports available in national and international data repositories. The findings reveal that the closure of schools raise the vulnerability of underprivileged children as they are being deprived of their right to education and socio-emotional security. Present pandemic has led adverse situation, therefore disrupted delay or deny the right to education. It is time to rethink to adopt a new policy and mechanism to continue their education and to provide socio-emotional immunity in the time of emergency to address the gravity of crisis.

Physics of a Spinning Object Cyclic Inversion at an Orbital Flight
Authors: Usubamatov Ryspek , Bergander Marek
Published: November 2021

The opening up of space flights is going on with physical discoveries. One of them was a spinning object cyclic inversion revealed on the MIR space station classified in 1985. Later, the NASA International Space Station openly showed the same effect. This physical effect was an object of stare studying by physicists and mathematicians. They developed only approximated and numerical models on the level of assumptions. The inversion of the spinning objects in the condition of free flight is the subject of gyroscope theory. The mass of the spinning object at the orbital flight generates the system of the interrelated inertial torques that results from the action of the inertial torques produced by the curvilinear motion of the object around the earth. This system of the torques acting on the spinning object at an orbital flight manifests its cyclic inversions, which is the gyroscopic effects. The theory of the gyroscopic effects describes the method of application of the system of the inertial torques, the physics of all gyroscopic effects that manifested by any rotating objects under any condition of their motions.

Penelitian ini bertujuan untuk menganalisis kesalahan-kesalahan yang dilakukan siswa dalam mengerjakan soal pada materi determinan dan invers matriks. Jenis penelitian ini adalah penelitian kualitatif. Teknik pengumpulan data yang digunakan adalah teknik tes dan wawancara secara daring. Subjek penelitian yaitu 30 siswa XI MIA 1 MAN 3 Kota Pekanbaru tahun pelajaran 2020/2021. Analisis kesalahan siswa dilihat berdasarkan objek matematika menurut Soedjadi yaitu fakta, konsep, prinsip, dan operasi. Hasil analisis kesalahan menunjukkan bahwa kesalahan paling banyak dilakukan siswa adalah kesalahan konsep dengan persentase sebesar 17,3%. Penyebab terjadinya kesalahan yang dilakukan siswa adalah siswa belum memahami konsep matriks, siswa lupa dengan konsep matriks dan kurang teliti dalam melakukan operasi perhitungan. Dalam pembelajaran, hendaknya guru tidak mengajarkan siswa untuk menghafalkan rumus namun lebih mengutamakan pemahaman konsep siswa. AbstractMost students sometimes make mistakes in solving math problems, either deliberately or unintentionally. This study aims to analyze the errors made by students in working on the questions on the determinant and inverse matrix material. This type of research is qualitative research. The data collection techniques used were online test and interview techniques. The research subjects were 30 students of XI MIA 1 MAN 3 Pekanbaru City in the 2020/2021 school year. Analysis of student errors is seen based on mathematical objects according to Soedjadi, namely facts, concepts, principles, and operations. The results of the error analysis showed that the most mistakes made by students were misconceptions with a percentage of 17.3%. The cause of the errors made by students is that students do not understand the concept of the matrix, students forget the concept of the matrix, and are not careful in performing calculation operations. In learning, the teacher should not teach students to memorize formulas but prioritize students' understanding of concepts.
