Authors: GIRI RISHABH , Vikas Kunwar Singh  , Ruchika Tiwari  , Gaurang Thanvi
Published: November 2020

Background and objective: Orbital floor fractures are very common in current day to day scenario. Till date different treatment modalities have been tried to reconstruct the orbital fractures. Conventionally various transorbital approaches have been used. But in cases where there is involvement of posterior part of orbit there is drawback of incomplete accessibility. To overcome this endoscopic assistance tends to get mandatory through trans-antral approach for better visualization, providing a good alternative to conventional approach.

Case Report: A 55-year-old male patient with pure blowout fracture along with persistent diplopia and enophthalmos was operated with sub tarsal approach along with trans antral approach using endoscope.

Result: The post-surgical results were satisfactory in respect to correction of diplopia and enophthalmos.

Conclusion: Conventional approach assisted with endoscope provides a new method of managing Orbital floor fractures improving treatment outcomes.
Magnetic peristaltic pumps for stowing operations
Authors:   Saint Petersburg Mining University, VASILYEVA Maria Aleksandrovna
Published: December 2020

Relevance of the work. The use of laying the workings is intended to increase the safety of mining operations, namely, controlling mining pressure, reduce mineral loss during excavation, prevent the occurrence of underground fires, and reduce the risks of destruction of objects in residential areas. Methodology of the work. The article is devoted to the study of the possibility of applying the system of peristaltic transportation of pasty slurries using the energy of a traveling magnetic field to work on the laying of the goaf. Taking into account the features of the materials used as the basis for filling mixtures, the specifics of the process of moving the latter to the place of laying, innovative technologies for transporting filling mixtures are becoming increasingly important. Results and scope. A fundamentally new approach to the transportation of liquid and viscous media is the use of low-frequency magnetic peristaltic pumps. The design of this pump involves the use as an executive body of the working channel, made of a magneto-active elastomer. By its extension under the influence of a traveling magnetic, periodic waves of local deformation pass, moving the filling mixture. Conclusions. The rejection of the traditional roller system, which presses the channel, and the replacement of the main executive body of the pump with the working channel, the structuring flow and preventing its separation, will expand the scope of application of pumping equipment during filling operations. The pressure developed by the pump depends on the energy characteristics of the traveling magnetic field. Studies have shown that the speed of movement of a wave of local deformation when moving various materials is sufficiently stable and slightly depends on the viscosity of a substance.

Published: December 2020

Problem Statement. Urban grounds have an artificial origin, they are formed as a result of construction activities, contain solid waste products and pollutants along with natural mineral and organic raw materials. Not all the cities have a system of registration of the urban ground types. The assessment of the pollution degree of urban grounds plays a key role in the environmental quality assessment in urban areas. The objective of the study is to conduct quantitative assessment of pollution with heavy metals for the urban grounds (on the example of Ekaterinburg, Russia). The material for the study is represented by the results of environmental engineering surveys conducted in Ekaterinburg in 2012–2015. The samples of the urban ground were collected with vertical stratification to a depth of 7 m in different geographical parts of the city. The content of Pb, Zn Cu, Mn and Ni, and the level of acidity were determined in the urban ground samples. Results. The analysis of vertical ground profiles showed a decrease in Pb, Zn and Ni content with increasing the depth. The accumulation of typical pollutants for urban environment (Pb, Zn and Cu) was found in the upper ground layer 0-20 cm. The metal content in the layer 0-20 cm was up to 5 times higher than the metal content in the lower horizons with a twofold decrease in metal concentration to depth of 1 m. In artificial ground in Ekaterinburg, there was a tendency to alkalization of soils with increasing depth (pH of the surface layer 0–20 cm was 6.5, when pH value was close to 8 at the depth > 4 m).

Game-theoretic modeling of market participants' behavior: case of Russian Adjustable-Rate Bonds with Puts
Authors:   St. Petersburg State University, Okulov Vitaly L. , Zhilina Polina S. ,   St. Petersburg State University
Published: December 2020

Adjustable-Rate Bonds with Puts (ARBP), frequently issued by the Russian companies, give the issuer the right to arbitrarily change the coupon payments on the bonds at certain moments. But at these moments, the investor has the right to force the issuer to redeem the bonds at a face value. These reciprocal actions of the issuer and investors can be considered as a dynamic game. We suggest a game-theoretic model that allow to determine the optimal decisions of the players. These decisions are compared with empirical data.
Looking forward approach with random horizon in cooperative differential games
Authors:   St. Petersburg State University, Petrosian Ovanes ,   National Research University Higher School of Economics, Pogozhev Sergei ,   St. Petersburg State University
Published: December 2020

In the paper authors present a new approach to determination and computation of a solution for differential games with prescribed duration in the case when players lack certain information about the dynamical system and payoff function on the whole time interval on which the game is played. At each time instant players receive information about dynamical system and payoff functions, however the duration of the period of this information is unknown and can be represented as a random variable with known parameters. At certain periods of time the information is updated. A novel solution is described as a combination of imputation sets in the truncated subgames that are analyzed using Looking Forward Approach with random horizon. A resource extraction game serves as an illustration in order to compare a cooperative trajectory, imputations, and imputation distribution procedure in the game with Looking Forward Approach and in the original game with prescribed duration. Looking Forward Approach is used for constructing game theoretical models and defining solutions for conflict-controlled processes where information about the process updates dynamically.
Koncepcja przebóstwienia w systemie Jana Szkota Eriugeny
Authors: Grzegorzyca Adam
Published: November 2020

W systemie filozoficznym Jana Szkota Eriugeny wszystko, co istnieje, to natura złożona z bytów i niebytów. Poznawalne dla ludzkiego intelektu części natury to byty, natomiast niepoznawalne (w sensie absolutnym) części natury to niebyty. Bytem jest zmysłowa część natury ludzkiej oraz rzeczywistość materialnych form. Dla ludzkiego intelektu Niebytem jest Bóg oraz ustanowione przez Niego prymordialne przyczyny i materia (w swej istocie). Bóg stworzył wszystko z niczego w ludzkiej naturze. Nierozumny wybór człowieka doprowadził do upadku ludzkiej natury i stworzenia, które z doskonałości przeszło do istnienia w świecie doczesnym. Syn Boży – Bóg-Logos stał się człowiekiem, który dokonał odkupienia ludzkości. W ostatecznych czasach rzeczywistość materialna zostanie zniesiona i stworzenie w ludzkiej naturze dostąpi powszechnego powrotu do pierwotnej doskonałości. Ludzkie intelekty dokonają własnego – ostatecznego (samo)sądu i wybrani skierują się ku Stwórcy. Następnie dojdzie do przebóstwienia wybranych – zjednoczenia stworzenia ze Stwórcą bez zmieszania natur, bez zniesienia fundamentalnych różnic ontologicznych oraz bez panteizmu, który w tej koncepcji jest wykluczony. Przebóstwieni będą kontemplować Boga, co oznacza, że będą wiecznie poznawać Niepoznawalnego. Wydaje się, że nawet dla ludzi zgłębiających załomy filozoficznej wiedzy o Bogu w XXI wieku ta szczęśliwa wizja przebóstwienia, które będzie nieustannym procesem poznawania Niepoznawalnego, może być atrakcyjna.
Elucidating the Risk Factors for Progression from Amyloid-Negative Amnestic Mild Cognitive Impairment to Dementia
Authors: Kim Hyung-Ji , Lee Jae-Hong , Cheong E-nae , Chung Sung-Eun , Jo Sungyang , Shim Woo-Hyun , Hong Yun J.
Published: December 2020

Background:

Amyloid PET allows for the assessment of amyloid β status in the brain, distinguishing
true Alzheimer’s disease from Alzheimer’s disease-mimicking conditions. Around 15-20%
of patients with clinically probable Alzheimer’s disease have been found to have no significant
Alzheimer’s pathology on amyloid PET. However, a limited number of studies had been conducted on
this subpopulation in terms of clinical progression.

Objective:

We investigated the risk factors that could affect the progression to dementia in patients
with amyloid-negative amnestic mild cognitive impairment (MCI).

Methods:

This study was a single-institutional, retrospective cohort study of patients over the age of 50
with amyloid-negative amnestic MCI who visited the memory clinic of Asan Medical Center with a
follow-up period of more than 36 months. All participants underwent brain magnetic resonance imaging
(MRI), detailed neuropsychological testing, and fluorine-18[F18]-florbetaben amyloid PET.

Results:

During the follow-up period, 39 of 107 patients progressed to dementia from amnestic MCI.
In comparison with the stationary group, the progressed group had a more severe impairment in verbal
and visual episodic memory function and hippocampal atrophy, which showed an Alzheimer’s diseaselike
pattern despite the lack of evidence for significant Alzheimer’s disease pathology. Voxel-based
morphometric MRI analysis revealed that the progressed group had a reduced gray matter volume in
the bilateral cerebellar cortices, right temporal cortex, and bilateral insular cortices.

Conclusion:

Considering the lack of evidence of amyloid pathology, clinical progression of these subpopulation
may be caused by other neuropathologies such as TDP-43, abnormal tau or alpha synuclein
that lead to neurodegeneration independent of amyloid-driven pathway. Further prospective studies
incorporating biomarkers of Alzheimer’s disease-mimicking dementia are warranted.
Ewing Sarcoma Family Tumors: Past, Present and Future Prospects
Authors: Abbas Adil , Alaa Mohammed N.S.
Published: November 2020

Ewing’s sarcoma (ES), also known as mesenchymal primitive neuroectodermal tumor
(PNET), is a malignant round blue cell tumor (MRBCT) with a varying degree of neuronal differentiation.
PNET arises from the primitive nerve cells of the central nervous system (CNS) but may
also occur in the bones of the extremities, pelvis, vertebral column, and chest wall. Extraskeletal
ES/PNET may affect the various soft tissues, including those of the pelvis, paraspinal region, and
thoracopulmonary region.

Histopathological differentiation between ES, PNET, and other related sarcomas is often difficult.
On light microscopy, the same histopathological appearance of ES has been termed PNET, Askin-
Rosay (A-R) tumor, and malignant neuroepithelioma by various other authors. The immunohistochemical
distinction is also difficult due to poor tissue differentiation and low intake of the various
specific immunohistochemical markers. The most frequent translocation is t (11; 22) (q24; q12), resulting
in the EWSR1-FLI1 fusion gene detected in nearly 90% of cases and is considered the hallmark
of the diagnosis of ES, PNET, atypical ES, and A-R tumor. Therefore, ES, atypical ES,
PNET, and A-R tumor are currently regarded as one entity grouped together under the Ewing Family
Tumor (EFT) and are treated in an identical way. EFT represents only about 3% of all pediatric
malignancies. The annual incidence is between 2 and 5 cases per million children per year. The
peak prevalence of the tumor is between the ages of 10 and 15 years. The incidence is higher in
males than in females, with a ratio of 1.3:1.

Newer groups of MRBCT that have great similarities to EFT are being recently described. These tumors,
atypical EFT and Ewing’s like Sarcomas (ELS), bear similarities to EFT but have basic morphological
and molecular differences. Optimal treatment requires the use of adjuvant and new-adjuvant
chemotherapy (CTR), radical surgical resection and/or involves field radiotherapy (RT). The
reported disease-free survival (DFS) and overall survival (OS) range between 45-80% and 36-71%,
respectively. The overall prognosis for the metastatic and recurrent disease remains poor. The use
of newer conventional and targeted medications, improved RT delivery, and surgical techniques
may further improve the outcomes. The past few years have seen advances in genomics-based sarcoma
diagnosis and targeted therapies. In this comprehensive review article, we provide a detailed
report of EFT and discuss the various clinical aspects and the recent advances used in the diagnosis
and treatment.
Aneurysm of the Communicating Vein Between the Left Renal Vein and Left Ascending Lumbar Vein Mimicking Retroperitoneal Lymphadenopathy: A Case Report
Authors: Arslan Sevtap , Sarıkaya Yasin , Karcaaltincaba Musturay , Karaosmanoglu Ali D.
Published: November 2020

Introduction:

Aneurysm of the communicating vein between the left renal vein and left
ascending lumbar vein is extremely rare, with only anecdotal reported cases. Unless detected and
recognized promptly, this rare condition may give rise to severe bleeding in patients undergoing
retroperitoneal surgery. It may also closely mimic enlarged retroperitoneal lymph nodes, paragangliomas,
adrenal masses, or renal artery aneurysms.

Case report:

In this case study, we reported the imaging findings of this rare entity which was falsely diagnosed as
enlarged retroperitoneal lymph node in an outside medical center, reported as to be consistent with metastatic disease, in a
patient with newly diagnosed testicular cancer.

Conclusion:

The aneurysm of the communicating vein should be considered in the differential diagnosis in patients with
testicular cancer and other disease processes where lymph nodes are commonly affected.

Cilj: Endemska nefropatija (EN) je kronična bubrežna bolest koja nastaje zbog dugotrajnog izlaganja aristolohičnoj kiselini. EN je povezan s razvojem terminalnog stadija bubrežne insuficijencije, ali i s razvojem karcinoma urotela, poglavito gornjeg dijela mokraćnoga sustava. U radu ćemo prikazati pacijenticu s endemskom nefropatijom, u koje se nakon presađivanja bubrega razvio panurotelijalni karcinom. Prikaz slučaja: U 76-godišnje pacijentice s EN-om je 2013. godine učinjena uspješna kadaverična transplantacija bubrega. Nakon transplantacije otkriven joj je površinski karcinom mokraćnoga mjehura koji je više puta liječen transuretralnim putem. Zbog pojave karcinoma u gornjem dijelu mokraćnoga sustava učinjena joj je i obostrana nefroureterektomija. Unatoč promjeni imunosupresivne terapije i kirurškom liječenju razvila se metastatska bolest uz letalni ishod tri godine po transplantaciji uz funkcionirajući presadak. Zaključak: U pacijenata s EN-om može doći do razvoja panurotelijalne bolesti, a posebno su ugroženi pacijenti u kojih je učinjena transplantacija bubrega. U ove skupine pacijenata vrlo je važna prijetransplantacijska obrada, kao i praćenje nakon transplantacije bubrega.

An Individual Cognitive Stimulation Therapy App for People With Dementia and Their Carers: Protocol for a Feasibility Randomized Controlled Trial
Authors: Rai Harleen Kaur , Schneider Justine , Orrell Martin
Published: December 2020

Background

There is a need for more resources to support the cognition and quality of life of people with dementia. The individual cognitive stimulation therapy (iCST) app aims to provide cognitive stimulation and social interaction to people with dementia and carers through interactive touchscreen technology. The iCST app has been developed according to the principles of CST and iCST, which have previously shown to improve the cognition and quality of life of people with dementia and benefit the relationship between the person with dementia and his/her carer. The iCST app has also shown to improve the quality of the carer’s life.

Objective

The aim of this study is to evaluate the usability of the iCST app intervention and the feasibility of conducting a full-scale randomized controlled trial (RCT) to assess the clinical effectiveness of the iCST app intervention compared to that of treatment-as-usual for people with mild-to-moderate dementia.

Methods

We aim to recruit 60 people with mild-to-moderate dementia and their informal carers as dyads in a multi-center feasibility RCT with a treatment-as-usual control group. Both parties must be able to provide informed consent and participate in the intervention. Dyads will complete a baseline assessment that will include cognition and quality of life measures and they will subsequently be randomized (1:1) to the iCST app intervention in addition to usual care or to usual care only. All participants will be followed up at 5 weeks and at 11 weeks after the baseline assessments. A range of feasibility outcomes will be assessed, including recruitment and retention rates, intervention fidelity and usability, and acceptability of the outcome measures. A sample of the experimental group will be invited to a semistructured posttrial interview to further examine the experience of using the iCST app.

Results

This study received funding in May 2015 and obtained ethical approval in March 2018. Data collection began in November 2018 and was completed in March 2020 with a total of 61 dyads recruited. Data analyses are in progress and the final results are expected to be available in the spring of 2021.

Conclusions

This study will investigate whether it is feasible to conduct a full-scale RCT to evaluate the clinical effectiveness of the iCST app in comparison to that of usual care alone. In addition, this study will examine the usability of the iCST app. The data will provide information on potential modifications to be made to the intervention, study design, and study process.

How to Address Your Instructor: An Analysis of Classroom Discourse at Saudi Arabian Universities
Authors: Abalkheel Albatool Mohammed
Published: December 2020

Hofstede’s (1986) concept of national culture includes the key dimension of how power distance affects interactions between interlocutors on all levels and settings of a society, including that of the university. An examination of such interactions, including the expected linguistic behaviors of instructors and students, is quite useful, because cultural values and the archetypal roles of instructors and their students tend to shed light on the relationships and general atmosphere of not just the higher education setting, but also of the society as a whole. In the large power distance culture of Saudi Arabia, this concept is examined through an analysis of the different address terms students use in classroom discourse to address their instructors. Since the use of titles is related to classroom interaction, it is affected by power distance. This study investigates and analyzes the discourse of the classroom in Saudi universities to identify titles and address terms used in student-instructor communications. The research found that the terms students employ with instructors include social and academic terms; whereas first and last names were usually avoided. Effects of potential factors are explained in terms of Hofstede’s (1986) concept of power distance.

Temperature is one of the most important ecological factors which play a significant role on the earth, and all the living organisms have evolved various methods to meet extremes of temperature. Seasonal temperature variations are quite significant in freshwater lakes and ponds. The present study deals with the effect of seasonal variations of water temperature on different water quality parameters of Tamdil lake, Mizoram, India, for a period of two years, i.e., from March, 2014 to February, 2016. The water samples were collected from five sampling sites, and the average reading was calculated for each of the water quality attributes namely, temperature, pH, Dissolved Oxygen (DO) and Biological Oxygen Demand (BOD). The water samples were analyzed monthly, and the results are computed on seasonal basis, i.e., pre-monsoon, monsoon, post- monsoon and winter seasons. Statistically, there was a positive and significant relationship between water temperature and pH, and negative significant relationship between temperature and DO. A negative correlation was observed between temperature and BOD. The result shows that there is a significant seasonal variation in physico-chemical parameters. The lake has not reached the polluted stage yet.

Dam site selection is an important task in water resource management and it depends on a number of biophysical as well as socio-economic factors. Dam site selection is becoming important research area due to the increase of water scarcity and also to prevent flood in certain area. This paper presents Multi Criteria Decision Making (MCDM) approach in water resources management through the integration of Analytic Hierarchy Process (AHP) and Technique for Order of Preference by Similarity to Ideal Solution (TOPSIS). These methods were applied for identification of suitable dam site in Tlawng sub-basin. The influential criteria for dam site selection were initially identified through literature review and experts opinion which was followed by the selection of four (4) feasible sites after having studied Tlawng watershed. Lastly, AHP and TOPSIS were applied to determine the relative weight and rank respectively.

Published: December 2020

Introdução: A trigonocefalia consiste no fechamento prematuro da sutura metópica sendo considerada o segundo tipo mais frequente de craniossinostose. Esta condição resulta no crescimento restrito do osso frontal e abaulamento local. O diagnóstico é clínico e o tratamento cirúrgico. Apresentação do caso: Paciente masculino de 7 meses e 30 dias de vida com assimetria craniana. Investigação clínica e por imagem evidenciou hipodesenvolvimento do osso frontal, presença de saliência óssea na linha média frontal, sem outras alterações ao exame neurológico. Encaminhado à cirurgia para correção de trigonocefalia não sindrômica. Discussão: A trigonocefalia compõe o grupo das craniossinostoses, malformações de fechamento prematuro das suturas cranianas. A grande maioria corresponde a casos isolados, não-sindrômicos e envolvem apenas uma sutura. O diagnóstico é clínico, sendo corroborado principalmente pela tomografia computadorizada (TC). O tratamento é cirúrgico e tem como objetivo evitar a progressão das deformidades craniofaciais. A técnica cirúrgica deste relato consiste na incisão coronal em zigue-zague, osteotomia sem avanço e sem remodelamento orbitário, fato que não comprometeu o resultado estético. Além de exigir menor tempo cirúrgico e, por conseguinte, menor perda sanguínea. Conclusão: Este relato mostra-se relevante, uma vez que numerosas variações de técnicas cirúrgicas têm sido propostas. Novos estudos fazem-se necessários para aprimorar o manejo destas malformações e para definir a melhor estratégia cirúrgica a ser empregada.

A Síndrome de Brown-Séquard (SBS) é uma condição neurológica rara que se caracteriza pela hemissecção da medula espinhal e corresponde a aproximadamente 3% de todas as lesões medulares traumáticas, sendo mais comumente causada por arma branca. Clinicamente, apresenta-se com perda da motricidade voluntária ipsilateral à lesão, perda do tato discriminativo, da sensibilidade proprioceptiva e vibratória ipsilateral à lesão, e perda da sensibilidade termoalgésica contralateral à lesão. Relatamos o caso de um paciente, 42 anos, que desenvolveu SBS após sofrer ferimento por arma de fogo (FAF) em região cervical direita. A síndrome decorrente de FAF é evento incomum, por conseguinte, conhecer a semiologia neurológica e a realização de propedêutica adequada é de inestimável relevância, pois contribuem para o diagnóstico correto e para a conduta apropriada

E agora, caro leitor, você está prestes a se tornar também meu confidente e – como dito acima – meu cúmplice. Espero contaminá-lo com o meu amor pela vida e com o otimismo que me foi inculcado por meus mestres, os quais continuam vivos em minha memória, pois, como dizia Bertold Brecht, “só se morre, de fato, quando se é esquecido”. Cada um destes mestres continua vivo. Vejo-os, ouço-lhes a voz e não raro pergunto-me o que me aconselhariam quando se me depara uma situação difícil. Creia ou não, caro leitor, isto me ajudou em mais de uma dificuldade intraoperatória.

Geografía lingüística: a brief insight into the variety of the Spanish language across Latin America
Authors:   University of Latvia, Feizaka Margarita
Published: December 2020

While there are studies on differences between traditional Spanish and Latin American Spanish, they tend to either compare Castilian Spanish to one national variation in Latin America (e.g. Mexican Spanish) or assume that the whole region of Latin America is rather linguistically homogenous. This research aims to provide a brief insight into differences between variations of the Spanish language spoken in different countries in Latin America, comparing three local dialects: Mexican, Venezuelan and Chilean. Qualitative content analysis and the comparative method were applied to conduct the research. The findings suggest that there are differences in grammar usage and lexicon between different countries. While phenomena like anglicisms and changing prepositions were detected in all local dialects, Mexican Spanish stood out in terms of grammar, and Mexican and Venezuelan Spanish vocabulary showed specific local expressions.

Published: November 2020

The article is devoted to the analysis of a very relevant topic at present: the process of transferring employees (employees) of an organization (company, firm, Department etc.) to a remote (remote) mode of operation, and thus creating a so-called virtual office. For the most part, the translation algorithm and organizational and technical support of the virtual office creation process are typical (universal). However, there is certain specificity in the organization and implementation of this process in relation to engineering organizations and high-tech industrial enterprises, due to the peculiarities of their activities in modern conditions of diversification of industrial production at the enterprises of the defense-industrial complex.
How Firms Fail at D&I
Authors: Leri Alice
Published: December 2020

This paper analyzes the impact that inclusive marketing practices might have on society using modest fashion as a case study. The study employs an ethnographic approach to discourse analysis and explores the impact of modest fashion in reshaping the boundaries of exclusion and belonging in the United States. Throughout the paper the author argues that as firms try to become more inclusive in the marketplace, they inadvertently perpetuated hegemonic and micro-hegemonic systems of belonging wherein non-threatening forms of otherness are assimilated into a safe "new normal" and liminal identities are further marginalized.

Published: November 2020

The steel industry is classified as a strategic industry that supports many industries, due to continuous national development. The steel industry must improve the quality of its production processes in order to increase its competiveness. One factor that supports the stability of the production process is the procurement process. To overcome the problem, the TOPSIS method is used to analyze supplier performance as a basis for determining supplier selection during the procurement process. Data is taken from the results of the questionnaire from the Material Procurement Division and the Vendor Management Office with criteria of price, quality, delivery time, suitability of the goods and Supplier Professionalism, and by choosing five alternative suppliers who are active in supplying goods. From the results of the questionnaire created a normalized matrix. Form the matrix determined distance with positive solution and negative solution alternative so we get a preference value for each alternative, and obtained PT. Siemen as a supplier with the closest relative proximity with a value of 0.6469.

This study aims to analyze defects in the sheet production process in the 301 Corrugator area by analyzing the total number of sheets produced and the number of sheets that have been damaged over a certain period of time using the Statistical Process Control (SPC) method and Failure Modes and Effect Analysis (FMEA). Based on the research results, there are 6 defects, namely untidy cuts, wrinkled sheets, uneven surface, curved sheets, uneven sides, loose sheet layers. The most dominant defect is uneven surface, which is 185.141 Kg or 60%. Based on the value of the RPN table, the product defect that has the highest value is the loose sheet layer with an RPN value of 245 from the calculation stage of the RPN value, a suggestion is made to reduce defects resulting from the loose sheet layer. From the stage of making improvements, the company should prioritize and focus on the types of disabilities and types of disabilities that have the highest RPN ranking when using the Failure Mode and Effect Analysis (FMEA) method.

Published: December 2020

Introduction: Anaphylaxis is a potentially life threatening allergic
reaction that is rapid in onset and multisystemic in nature.
Distribution of anaphylaxis tends to fluctuate based on age, gender,
race, geographical residence and socioeconomic status of the involved
subjects. Diagnosis of anaphylaxis in children is generally
underestimated particularly in developing countries, and when diagnosed,
proper management is occasionally lacking. Aim of the study: to evaluate
the frequency and pattern of anaphylaxis and mistakes in diagnosis and
treatment among a group of Egyptian children and adolescents. Subjects
and methods: This observational study was conducted over 6 months
duration, from 1st of September 2019 to the end of February 2020, in
Children’s hospital, Ain Shams University, Cairo, Egypt, on children
presenting to emergency department (ED). Anaphylaxis frequency,
presentation, triggers, diagnosis, management and long term follow up
were assessed. Results: frequency rate of anaphylaxis among children and
adolescents was 0.43% (80/18816) over a year. Sixty percent of patients
were infants. Biphasic reactions were reported in 11.3% of patients.
The commonest trigger was food (22.5%) followed by medications (8.8%).
Epinephrine was given to all patients, in proper dosage and method in
most occasions (78.7%). Long term management and follow up appointment
were deficient. In conclusion: Anaphylaxis in children was relatively
high, with food being the most common trigger. Diagnosis and early
management of anaphylaxis was satisfactory, however, long term
management and follow up were defective.
Development and Validation of an Interleukin-6 Nomogram to Predict Primary Non-response to Infliximab in Crohn’s Disease Patients: From Bedside to Bioinformatics.
Authors: Chen Yueying , Li Hanyang , Feng Qi , Shen Jun
Published: December 2020

Background: The primary nonresponse (PNR) rate of Infliximab (IFX)
varies from 20% to 46% for the treatment of Crohn’s disease (CD).
Detected PNR reduces the improper use of specific treatments. To date,
there is hardly any knowledge regarding early markers of PNR. The aim of
this study was to evaluate the role of Interleukin-6 (IL-6) as an early
predictor of PNR of IFX for the treatment of CD. Methods: We enrolled
322 bio-naïve patients diagnosed with CD from January 2016 to May 2020.
Primary response was determined at week 14. Multivariable logistic
regression was used to construct prediction models. The discrimination,
calibration and clinical validity of the models in the validation cohort
were assessed by area under the curve (AUC), calibration and decision
curves analyses. GEO data were analyzed to identify potential mechanisms
of IL-6 in IFX therapy for CD. Results: PNR occurred in 31.06% (100 of
322) patients who were assessable at week 14. IL-6 levels significantly
decreased after IFX therapy (P < 0.001). The validation model
containing IL-6 presented enhanced discrimination with an AUC of 0.908
and high calibration. Decision curve analysis (DCA) indicated that the
model added extra predictive value. GEO data confirmed the IL-6 levels
were increased in the PNR group and IL-6-related differently expressed
genes (DEGs) were enriched in the inflammatory response. Conclusion: We
concluded that IL-6 may be used as a predictive factor to assess the
risk of PNR to IFX therapy.
Complete recovery of deep venous thrombosis from Coombs (+) Thrombotic Thrombocytopenic Purpura: Case report
Authors: Zhou Mi , Yin Jie
Published: December 2020

Catheter-related DVT under the setting of TTP or TTP recovery stage may
be presented as a more fulminant form. Certain guidelines for
anticoagulation and antiplatelet therapy for thrombosis early should be
further established. We present here a case of a patient presented with
Comb (+) TTP and developed catheter-associated deep vein thrombosis
(DVT). The patient was firstly diagnosed with Evans syndrome. However,
he was refractory to a methylprednisolone pulse therapy with a
combination of platelet transfusion and eventually developed
microangiopathy of central nerve system. The immediate start of PEX
(1500ml/d) induced a complete remission of acquired TTP and
disappearance of neurological signs and symptoms. However, external
iliac and femoro-popliteal venous thrombosis was diagnosed subsequently,
inferior vena cava filter (IVC) filter was immediately planting
accompanied with anticoagulation therapy. Meanwhile, PEX session was
sustained as well as oral anticoagulant (rivaroxaban). 14 days later,
the patient got full recovery. Our report aims at raising awareness of
Catheter-related DVT under the setting of TTP should be cautious. It is
necessary to start anticoagulation and antiplatelet therapy for
thrombosis early, especially in such cases when PLT count >
50×109/L.

Background: Brazil is an upper-middle-income country in South America
with the world’s sixth largest population. Little is known on the
volume, outcomes and trends of coronary artery bypass grafting (CABG) in
Brazil’s public health system. Objective: The aim of this study was to
evaluate the outcome of CABG in the public health system in from January
2008 to December 2017 through the database DATASUS. Methods: This study
is based on publicly available material obtained from DATASUS, the
Brazilian Ministry of Health’s data processing system, on numbers of
surgical procedures, death rates, length of stay, and costs. Only
isolated CABG procedures were included in our study. We used the TabNet
software from the DATASUS website to generate reports. Chi-square test
was used to compare death rates. A p-value of <0.05 was
considered statistically significant. Results: We identified 226,697
CABG procedures performed from January 2008 to December 2017. The
overall in-hospital mortality over the 10-year period was 5.7%. We
observed statistically significant differences in death rates between
the five Brazilian macro regions. Death rates by state ranged from 2.6%
to 13.1%. The national average mortality rate remained stable over the
course of time. Conclusion: Over 10 years, a high volume of CABG was
performed in the Brazilian Public Health System with significant
differences in mortality, number of procedures, and distribution of
surgeries by region. Future databases involving all centers that perform
CABG and carry out risk-adjusted analysis will help improve Brazilian
results, and enable policymakers to adopt appropriate health care
policies for greater transparency and accountability.
