Published: November 2020

The direction of research on the development of a scientific and methodological tool for the analysis of spatial objects in order to determine their generalized spatial parameters was selected. An approach to the problem of modeling networks and groups of objects based on the synthesis of a weighted graph is proposed. The spatial configuration of objects based on the given conditions is described by a weighted graph, the edge length of which is considered as the weight of the edges. A generalization to the typical structure of a spatial graph is formulated; its essence is representation of nodal elements as two-dimensional (polygonal) objects. To take into account the restrictions on the convergence of the vertices described by the buffer zones, a complementary graph is formed. An algorithm for constructing the implementation of a spatial object based on the sequential determination of vertices that comply with the given conditions is proposed. Using the software implementation of the developed algorithm, an experiment was performed to evaluate the spatial parameters of the simulated objects described by typical graph structures. The following parameters were investigated as spatial ones

Published: November 2020

The necessity of oil and gas fields arrangement in the Extreme North and developing updated edition of rules’ for making engineering surveys codes, taking into account the specific features of the oil and gas fields territories with heaving mounds of permafrost (MMP) is considered in details. The developed models of temperature fields enable predicting possible deformation changes in the geospatial position of the underground and aboveground components of the heaving mounds. It is recommended that the corridor of linear communications be located at least 50 meters from the underground component of the heaving mound and 100 meters from the upper line of the intersection of the heaving mound with the earth’s surface. A new formula for determining the depth of thawing is proposed, taking into account the amount of seasonal thawing and the lateral influence of the heave hill. The research results are introduced in the production of engineering surveys in Samburg, Centillica and Yamburg.

Authors: Chan Jeremy , Basu Ayan , discenza gabriela , bartlett Jack , Fan Ka , Oo Shwe
Published: November 2020

Background: Aortic Valve Neocuspidization using glutaraldehyde-treated
autologous pericardium was first performed by Ozaki et al. in 2007. This
technique has become an alternative to tissue and mechanical valve as
long-term anticoagulation is not required and shows promising midterm
results and durability. Method: A comprehensive search was performed on
the major database using search terms “Ozaki technique” AND “Aortic
Valve Neocuspidization” AND “AV Neocuspidization” AND “Autologous
pericardium” AND “glutaraldehyde-treated autologous pericardium”.
Articles up to 1st of August 2020 were included in this study. Results:
A total of 9 studies with a total of 1342 patients were included. The
mean age was 67.36 and 54.23% were male. 66.32% and 23.92% of
patients had aortic stenosis and aortic regurgitation, respectively.
66% of patients had a native tricuspid aortic valve and 31.37 %
patients’ native aortic valve was bicuspid. Three studies reported their
experience performing Aortic Valve Neocuspidization via mini sternotomy.
Conclusion: Aortic Valve Neocuspidization is an alternative to
biological and mechanical prostheses for surgical aortic valve
replacement. The short and mid-term outcome are comparable without the
need for long term oral anticoagulation. Long term follow-up data is
required for this novel approach to be widely adopted.

Published: November 2020

Objective: To demonstrate that a double balloon catheter combined with
oxytocin decreases time between induction of labour and delivery (TID)
as compared to a vaginal dinoprostone insert in cases of PROM at term.
Design: Prospective, randomized, controlled trial. Setting: French
university hospital Population: Patients undergoing labour induction for
PROM at term with unfavorable cervix. Methods: We compared the double
balloon catheter over a period of 12 hours with adjunction of oxytocin 6
hours after catheter insertion, versus dinoprostone vaginal insert.
After device ablation, cervical ripening continued only with oxytocin.
Main outcome measures: The primary outcome was TID. Secondary outcomes
concerned delivery mode, maternal and fetal outcome and were adjusted
for parity. Results: 40 patients per group were randomized. Each group
had similar baseline characteristics. The study failed to demonstrate
reduced TID (16.2 vs 20.2 hours, ES = 0.16 (-0.27 to 0.60), p=0.12) in
catheter group versus dinoprostone except in nulliparous women (17.0 vs
26.5 hours, ES = 0.62 (0.10 to 1.14), p=0.006). The rate of vaginal
delivery <24h significantly increased with combined induction
(88.5% vs 66.6%, p=0.03). No statistical difference was observed
concerning caesarean rate (12.5% vs 17.5%, p>0.05),
chorioamnionitis (0% vs 2.5%, p=1), postpartum endometritis, maternal
or neonatal outcomes. Procedure-related pain and tolerance to devices
were found to be similar for the two methods. Conclusion: The double
balloon catheter combined with oxytocin is an alternative for cervical
ripening in case of PROM at term, and may reduce TID in nulliparous
women.
Epileptic Convulsions Probably Induced by Desloratadine, a Second-Generation H1-Antihistamine
Authors: Han Xiaonian , Zan Xin , Xiong Fengmei , Nie Xiaojing , Peng Lirong
Published: November 2020

Second-generation H1-antihistamines are generally considered to be safe.
Here we describe a healthy boy who developed left-arm convulsions after
repeated exposure to a dry suspension of desloratadine combined with
Huatengzi granules. The boy had no family or disease history of
epilepsy, convulsions, or any other drug therapy. The Naranjo Adverse
Drug Reaction Probability Scale was used to determine that the
convulsions were probably related to desloratadine. Our findings suggest
that desloratadine (a second-generation H1-antihistamine) can cause
epileptic convulsions in healthy children, and so clinicians should be
vigilant of the possibility of central side effects.

Objectives: To follow-up pediatric CF patients—in terms of health
status and nutritional status—via Telehealth services during the
COVID-19 pandemic. Additional aims were to measure the level of anxiety
in the patients and their parents, and to determine the COVID-19
transmission status in the CF patients. Materials and Methods: The CF
team supported the patients via remote contact, including dedicated
telephone lines. During Telehealth Services interviews, in addition to
obtaining information about the patients’ anthropometric measurements,
health status, and CF-related complaints, the State-Trait Anxiety
Inventory (STAI) was administered to the patients and the Hospital
Anxiety and Depression Scale (HAD) was administered to their parents.
Results: The study included 144 pediatric CF patients (74 male and 70
female). Mean age of the patients was 8.9 years. In all, 42 (29.2%) of
the patients were tested for COVID-19, of which 4 were positive. The
mean STAI score was significantly lower in the patient group than in the
control group (P < 0.001). The mean HAD anxiety score was
significantly higher in the parents of the CF patients, as compared to
the parents of the controls (P = 0.005). The mean HAD depression score
was also statistically higher in the parents of the CF patients (P
< 0.001). Conclusion: Telehealth is an innovative method for
providing healthcare services while maintaining social distancing,
avoiding the risk of exposure and spread of COVID-19. Telehealth
services reduce patients’ and parents’ anxiety, and increases their
confidence in managing CF-related complications.
An Experimental Study of L2 Acquisition of Mandarin Unaccusative Verbs by English-Speaking Learners
Authors:   School of Education and Languages, The Open University of Hong Kong, Wong Catherine Shee Hei
Published: November 2020

The present study investigates the acquisition of Chinese Mandarin unacussative verbs by English-speaking L2 leaners of Chinese, in light of Universal Grammar and Interlanguage (IL) phenomenon. The results of the experiment show that there is no strong evidence for the overpassivization of Mandarin unaccusative verbs, which calls into question the claim that the overpassivization phenomenon of unaccusative verbs is universal in second language acquisition (SLA). The L2 learners in our experiment performed better with non-alternating unaccusative verbs than alternating unaccusative verbs, which might suggest that learners were probably treating the alternating unaccusative verbs in our experiment as underlyingly transitive and thus accepted the ungrammatical passivized unaccusative verbs in the Grammaticality Judgement task. This phenomenon is consistent with child’s L1 development. We attribute the overpassivization of the Chinese unaccusative verbs in our experiment to the hypothesis of non-target lexical causativization as in L2 acquisition of English.
A educação (em tempo) integral no Brasil: um olhar sobre diferentes experiências
Authors: Vilas Boas Mariana Lubarino , Abbiati Andréia Silva
Published: November 2020

Os projetos de educação em tempo integral desenvolvidos por Anísio Teixeira (1950) e Darcy Ribeiro (1980) impulsionaram diferentes experiências educacionais no Brasil. Em vista disto, apresenta-se como objetivo deste artigo analisar algumas dessas experiências à luz de artigos científicos disponibilizados na plataforma da biblioteca online SciELO, no período de 2002 a 2019. A análise revelou que as concepções de educação integral e de educação em tempo integral permeiam as discussões e provocam dúvidas quanto à função social da educação em tempo integral. Além disso, a falta de infraestrutura das escolas de tempo integral é frequentemente apontada como fator impeditivo à realização de atividades primordiais desta forma de organização do ensino. Considera-se que são necessários maiores aportes de investimentos para que a jornada escolar ampliada cumpra seu papel transformador na educação brasileira, ou seja, a formação integral do estudante.

Published: November 2020

O artigo tem como objetivo descrever a gestão diretiva com o estresse laboral dos professores desde a pandemia Covid-19 na Escola San Ignacio de Viña del Mar, Região de Valparaíso, Chile. Para tanto, utilizou-se uma abordagem quantitativa, descritiva e exploratória. Os participantes foram atendidos por 87 educadores da referida instituição, submetidos a exame de censura em função da intensificação da investigação. Os resultados indicam que os professores estabelecem relações de colaboração com seus colegas de trabalho por meio da conectividade e ainda há necessidade de considerar competências e habilidades na realização da práxis educacional. Os achados constataram que o diretor da escola não articula os recursos necessários ao bom funcionamento do corpo docente. A situação de pandemia não tem impacto significativo sobre os resultados do estresse no trabalho percebido. Isso pode ser explicado pelo esforço que implica para o educador realizar seu trabalho pedagógico.
Sinterability and characterization of Ag/Al2O3 metal and ceramic matrix composites processed by mechanical milling
Authors: Davodi Ramin , Ardestani Mohammad , Kazemi Arqavan
Published: November 2020

In this research, the sinterability of Ag/Al2O3 milled powders with 10 and 90
wt%Ag were investigated. The powders were consolidated by two different
processes including conventional and spark plasma sintering. The
conventionally sintered composites with 90 wt%Ag were further densified by
cold pressing and subsequent annealing at 700?C. The microstructural
evaluations confirmed a fine dispersion of the constituents within the
microstructure of the spark plasma sintered composites. Moreover, the
results showed that the relative density, hardness, and flexural strength of
the spark plasma sintered samples were much higher than those of the other
samples. The hardness and flexural strength of Ag/10 wt%Al2O3 spark plasma
sintered samples at 650?C were 146 HV and 264 MPa, respectively. However,
unlike the composite with 90 wt%Ag, the applied sintering temperatures have
not led to the synthesis of an Ag/90 wt% Al2O3 composite with the desired
properties
Preparation and modification of inverse opal zirconia pigment

Published: November 2020

Inverse opal zirconia pigment prepared by traditional process has the
disadvantages of low color saturation and variegated color which restrict
its further application. In this work, the inverse opal zirconia pigment was
prepared by colloidal crystal template fabricated using polystyrene
microspheres with particle size of 340 ? 10 nm as raw material and further
modified by sintering at 600 ?C for 2 h with heating rate of 2 ?C/min in an
atmosphere tube of 0.8 L min-1 nitrogen flow. The morphology, phase
crystallinity and color performance of the inverse opal zirconia pigment
before and after modification were characterized in detail and the modified
mechanism was investigated. The results showed that morphology of the
inverse opal zirconia pigment before modification was basically a highly
ordered porous structure, the phase was relatively pure, and the overall
appearance was variegated color. Some parts of the samples exhibited low
color saturation and different areas showed various colors, indicating that
the samples had certain angle dependence. After modification, the samples
showed bigger-area single blue-green color, suggesting that the color
saturation was significantly improved and the angle dependence was reduced
evidently. The mechanism for modification was that the zirconia precursor
and polystyrene templates were carbonized when sintered in nitrogen
atmosphere. The generated in-situ carbon remained in the samples and
absorbed the tray background light, which significantly suppressed the
multiple scattering of structural defects.

Authors: Johnsy Arputhavalli , Agilan S. , Jebasingh S. , Vijay Joseph
Published: November 2020

In the present study, the wear resistance behavior and the microhardness of
the Co38Ni35Al27 and Co35Zn10Ni32Al23 ferromagnetic shape memory alloys
(FSMAs) were investigated. The alloy samples were prepared by powder
metallurgy method along with the vacuum sintering technique. The major aim
is to prepare an alloy with high wear resistance having remarkable
microhardness suitable for the sustainable shape memory alloy. The wear test
report shows that the wear resistance is high for the sample sintered at 673
K and it gradually reduces when the sintering temperature decreases. The
result also shows that the inclusion of zinc in the alloy increases the wear
rate. The maximum hardness value of 126 HV was observed in Co38Ni35Al27
sample sintered at 673 K for 8 hrs because of its minimal porosity.

Published: November 2020

No âmbito educacional, a ideologia da Ditadura, por meio da Doutrina de Segurança Nacional, foi um forte mecanismo de legitimação dos governos militares reverberando em reformas de todas as modalidades e níveis. Especificamente no caso da Educação Profissional, houve mudanças no currículo e acentuação, na rotina escolar, de regras, horários e disciplinamento. Além da forte aproximação com o modelo tecnicista que imprimia uma atmosfera de empresa à escola. Nosso objetivo neste artigo é realizar uma discussão teórica acerca da história oral e memória relacionada a cultura escolar da Escola Técnica Federal do Rio Grande do Norte-ETFRN (1968-1985), durante a Ditadura Militar. Dialogamos com Maurice Halbwachs, Michael Pollack e Ecléia Bosi, no que se refere a noção de memória, esquecimento e silêncio. E, no caso da história oral, as obras de Verena Alberti, Sebe Bom Meihy e Suzana Ribeiro, Alessandro Portelli, Ana Maria Mauad, nos deram as bases para a compreensão dos usos da história oral como arte da escuta e integrada aos novos tempos, ao fazer registros não só auditivos, mas também visuais/imagéticos. Associado a oralidade usaremos também outras fontes: escritas e visuais, como jornais da época, fotografias, diários de classe, currículos e etc. Consideramos que não há uma realidade unívoca, a mesma escola que regulava e disciplinava era a que, por meio de vivências múltiplas construía sujeitos críticos e capazes de ir além do saber fazer.

Does the Nature of Index and Liquidity Influence the Mispricing in Future Contracts in India?
Authors: Garg Deeksha
Published: November 2020

In this study, we investigate the variations in the mispricing of futures in Nifty (benchmark index), Bank Nifty and Nifty IT. Using a regression model on 1230 observations for the period of 1 January 2014 to 31 December 2018, we find no significant mispricing exists in the last week to the expiry of the contract in all three indices. This finding supports the existing literature that as the contract moves towards the maturity date, its value converges the market value. However, the main highlight of the paper is to reveal the difference in the life of mispricing in different indices. This difference in mispricing can be allocated to the liquidity in that indices. We report that being the most liquid, Bank Nifty is having mispricing only in 1 week (first week) of the contract, after that no significant mispricing exists in mispricing, Nifty shows significant mispricing for the first two weeks and Nifty IT shows mispricing for all weeks except last week. This is the pioneering work which considers the sectoral differences while evaluating futures mispricing. The findings of this study will provide a useful insight to the regulator and investors.
A Network Analysis of the Asia-Pacific and Other Developed Stock Markets: Pre and Post Global Financial Crisis
Authors: Guhathakurtha Kousik , Bhattacharya Sharad Nath , Bhattacharya Mousumi
Published: November 2020

This paper examines the volatility spillover and connectedness between Asia-Pacific, US, UK, and eurozone stock markets. A spillover index is built using forecast error variance decomposition in a vector autoregression framework and the spillover index is used to build network diagrams. It shows evidence of how the increase in risk transfer (volatility spillover) between the markets led to the global financial crisis and of the higher level of connectedness since. Network diagrams show the direction and strength of the connectedness. The network strength estimation enables us to understand the risk associated with connectedness across the markets in the event of a trigger and its influence in portfolio management decisions of international funds. The Chinese market appears to be the most insulated, while the South Korean, Hong Kong, and Singapore stock markets dominate in terms of risk transfer. The US, UK, EU, Singapore and Hong Kong are the top five volatility spillover recipient markets, both during pre and post global financial crisis periods. We find the market size to be irrelevant in the determination of the level of connectedness, whereas the role of geographical proximity cannot be ruled out. The findings are relevant to multinational investment strategies and in understanding the relative risk of investment in the Asia-Pacific region.
Planning simulation experiments in problems of studying operational strategies of container terminals
Authors: Kuznetsov Alexander Lvovich , Kirichenko Alexander Viktorovich , Semenov Anton Denisovich , Radchenko Anna Aleksandrovna
Published: November 2020

The article describes the problem of the effectiveness of different container stacking strategies, which has been the matter of research in many scientific works. The methods of substantiating the strategies vary from mathematical calculations to practical application. There has been set the task to prove the adequacy of the new container stacking strategy. The application of different strategies for container terminals is found not reliable due to rapid changes of operating conditions and insufficient amount of data that can be collected for the short period of a strategy application. It is proved that the only reliable method that provides the independent proof of the efficiency of container stacking strategies is simulation modelling. Special attention in the studies should be given to planning of the experiments. To compare the strategies it is proposed to use multiple experiments with different parameters of the incoming and outgoing traffic. There is presented a case of comparison of strategies for finding a minimum over the entire stack and stacking containers based on their shelf life. When analyzing the strategies for storing containers it is necessary to determine the optimality criterion, since the attractiveness of a particular strategy will depend on the selected optimized parameter. As a criterion of optimality in the given example, the complexity of the selection of containers is taken, which is determined by the average number of movements required to select one container. It is justified that according to the optimality criterion, the best strategy takes into account the storage periods of containers.

Published: November 2020

The article discusses the results of experiments on measuring vibration of the hull of a small vessel using various methods of vibroinsulation of outboard motors SEA PRO (nominal capacity 5 h.p.) and SEA PRO (nominal capacity 2.5 h.p.). There have been recorded the harmful effects of prolonged exposure to vibration on the human body, as well as on the boat hull and outboard motor. The peak vibration level was measured and the effectiveness of different types of vibroinsulation was evaluated. The experiments were carried out using a vibrometer Ekofizika-110A made in Russia (relative measurement error ± 0.5 dB) and a vibrometer AR63A made in China (relative measurement error ± 5%). The illustrations of the vibrometers used are presented. It was determined that a multi-layer transom cover is a fairly effective way to reduce the vibration of the motor boat hull. The highest efficiency was achieved for the outboard motor SEA PRO 5.0 when it was running at full speed; a 17.3% reduction in vibration was recorded when using the relative value of vibration acceleration (dB). For the outboard motor SEA PRO 2.5 running at medium speed the decreased vibration (9.5%) was recorded when using the relative value of vibration acceleration (dB). The conclusion has been made about the prospects of reducing the vibration of outboard motors and the need for scientific and experimental research, as well as for the development of standards for permissible vibration of the motor boat hull, which can limit the harmful effect on the crew, the boat structure and the outboard motor. The formula of the logarithmic levels of vibration acceleration in relative units is given in accordance with generally accepted sanitary rules and regulations.

Published: November 2020

The article presents a detailed analysis of the technogenic risks in building and operating oil and gas complexes in the offshore area of the Caspian Sea and actualizes the problem of the Caspian environmental crisis, the possible measures for preventing and minimizing the negative consequences from the extensive offshore oil and gas production for the ecosystem being considered. The geothermal regime of the ground of the Caspian Sea has been analyzed in respect of the deep-earth processes. The bottom of the Caspian Sea is rather varied, hence, the risks for constructing facilities in the area under development are possible. The surface, underwater and island mud volcanoes formed by the large longitudinal and transverse tectonic disturbances pose a threat to oil production and transportation facilities. The tectonic processes of the bottom of the Caspian Sea are studied in detail. It has been stated that the global geodynamic processes are taking place in the earth's crust of the region affecting the natural environment of the Caspian Sea, which will inevitably affect the industrial objects on the shelf. The Caspian Sea ground is divided into two parts in terms of seismic activity: the seismically inactive northern part (the Scythian-Turanian platform and the East European platform) and the southern part (alpine orogenic-folded belt) that is currently seismically active. The diagrams of possible earthquakes and seismic activity in the bottom area of the Caspian Sea are presented. Since the mechanism of the developing seismic activity caused by volcanoes is not fully examined, there has been substantiated the need to prognose precisely the location of hazardous zones and joints in connection with the development of the oil and gas industry. The tectonic and geological frame of the Caspian region has been illustrated; the regional fractures that influence the formation of biosphere zones and the largest tectonic joints that affect natural and man-made processes are noted. Particular attention is paid to the risks of the hydrogen sulfide pollution of the Caspian Sea. Conclusions are drawn about the prospects for the development of the Caspian, which is rich in oil and gas reserves; on the need to ensure safety and reduce losses in the ecological system of the Caspian Sea.

Riset ini bertujuan untuk menentukan dosis kalium diformat (KDF) yang paling efektif dalam pakan untuk meningkatkan performa kesehatan ikan bawal air tawar (Colossoma macropomum). Riset ini menggunakan Rancangan Acak Lengkap (RAL) dengan 4 perlakuan dan 4 ulangan. Perlakuan yang digunakan adalah penambahan KDF pada pakan komersil (0%, 0,1%, 0,3% dan 0,5%). Setelah 35 hari pemberian KDF, ikan diuji tantang menggunakan Aeromonas hydrophila dengan kepadatan 108 cfu/ml secara intraperitonial, kemudian diamati selama 14 hari. Parameter yang diamati adalah kelangsungan hidup, jumlah sel darah putih, jumlah sel darah merah dan gejala klinis makroskopis. Hasil riset menunjukkan bahwa jumlah leukosit seluruh perlakuan meningkat sampai hari ke-7 dikarenakan adanya infeksi, kemudian jumlah leukosit menurun kembali pada hari ke-10 menuju kondisi normal. Jumlah eritrosit seluruh perlakuan menurun sampai hari ke-10, hal ini disebabkan oleh adanya aktivitas hemolitik dari A. hydrophila dan kembali meningkat menuju kondisi normal pada hari ke-14. Gejala klinis makroskopis seluruh perlakuan cenderung seragam yaitu sisik mengelupas, bercak merah, perut membengkak dan sirip geripis. Dapat disimpulkan bahwa perlakuan KDF 0,3% merupakan perlakuan terbaik karena memiliki nilai kelangsungan hidup tertinggi setelah uji tantang yaitu sebesar 55%.

An Analysis of Perceived and Actual Anticoagulant Knowledge among Independent Pharmacy Patients
Authors: Ware Kenric , Faile Marty , Lynch Carrie
Published: November 2020

Background: Deficits in knowledge of parameters surrounding anticoagulant therapy administration carry substantial risks for patient harm. Patients prescribed anticoagulants may overestimate their knowledge of anticoagulant use principles. The purpose of this study was to analyze independent pharmacy patients’ perceived versus actual knowledge of their anticoagulation therapies.
Methods: A 15-item survey across a dual-site pharmacy location evaluated patients’ confidence in their understanding of anticoagulant prescribing parameters and their awareness of measures to take to safeguard anticoagulant therapy routines. A pharmacist reviewed patient responses to survey items referencing actual understanding of anticoagulant therapies at the conclusion of the survey. Data analyses occurred by gender, age, ethnicity, location, living situation, self-management of anticoagulants, patient perception of anticoagulant safety, and reported receipt of anticoagulant education. Linear regressions were used for statistical analyses, with significance set at p<.05.
Results: During the span of three months, 45 patients, 20 females and 25 males, completed the survey. Perceived anticoagulant knowledge did not differ significantly by demographics. Actual anticoagulant knowledge declined by over 20% between age groups 60-69 and 80-89 years old. African Americans displayed 10% lower actual anticoagulant knowledge than Caucasian Americans.
Conclusions: This study revealed gaps in knowledge of anticoagulants among patients at an independent pharmacy. An appeal remains for more strategies to assist with knowledge of anticoagulant regimens. Healthcare institutions should continue to incorporate programs geared towards ongoing anticoagulant education, such as question and answer sessions, along with peer support mediums that foster optimal outcomes.

Merkel Cell Carcinoma Presenting as an Indurated Plaque
Authors: Maxi Margaret Coleman , Byrne Joel , Martin Ardenne , Martin Pamela
Published: November 2020

Merkel Cell Carcinoma (MCC) is a rare and aggressive neuroendocrine carcinoma that most commonly occurs in elderly Caucasian males who have a history of extensive sun exposure. Most cases of Merkel Cell Carcinoma (MCC) present in the outpatient setting and include a single, asymptomatic, red or pink lesion on sun exposed areas with a diameter less than 2 cm. There was a threefold increase in the incidence of MCC from 1986 to 2001, and the incidence of MCC is predicted to continue to increase secondary to the aging “baby boomer” population.To our knowledge, there are only two case reports that describe MCC resembling and receiving the diagnosis of cellulitis at initial presentation. We report an unusual case of MCC presenting as suspected cellulitis of the chest wall in an elderly Caucasian male.

Purpose: A clinical hurdle for dermatopathology is the accurate diagnosis of melanocytic neoplasms. While histopathologic assessment is frequently sufficient, high rates of diagnostic discordance are reported. The development and validation of a 35-gene expression profile (35-GEP) test that accurately differentiates benign and malignant pigmented lesions is described.
Methods: Lesion samples were reviewed by at least three independent dermatopathologists and included in the study if 2/3 or 3/3 diagnoses were concordant. Diagnostic utility of 76 genes was assessed with quantitative RT-PCR; neural network modeling and cross-validation were utilized for diagnostic gene selection using 200 benign nevi and 216 melanomas for training. To reflect the complex biology of melanocytic neoplasia, the 35-GEP test was developed to include an intermediate-risk zone.
Results: Validation of the 35-GEP was performed in an independent set of 273 benign and 230 malignant lesions. The test demonstrated 99.1% sensitivity, 94.3% specificity, 93.6% positive predictive value and 99.2% negative predictive value. 96.4% of cases received a differential result and 3.6% had intermediate-risk.
Conclusions: The 35-GEP test was developed to refine diagnoses of melanocytic neoplasms by providing clinicians with an objective tool. A test with these accuracy metrics could alleviate uncertainty in difficult-to-diagnose lesions leading to decreased unnecessary procedures while appropriately identifying at-risk patients.

Published: November 2020

Background:

We describe the technical report and results of the first image-guided, linear accelerator, frameless radiosurgical third ventriculostomy.

Methods:

We report a 20 years old man, with diplopia, balance disturbances, and limitation for gaze supraversion. Magnetic resonance imaging resonance imaging of the brain and cranial computed tomography showed showed a left thalamic-midbrain lesion that caused partial compression of the Silvio aqueduct and mild ventricular dilatation. The biopsy revealed the diagnosis of pleomorphic xanthoastrocytoma. Before radical treatment of the tumor with fractionated stereotactic radiotherapy, the patient underwent to frameless radiosurgical third ventriculostomy, on the TrueBeam STX® platform with the ExacTrac localization system. The target used was the one defined on the floor of the third ventricle, at the midpoint between the mammillary bodies and the infundibular recess. The prescription dose was 120 Gy, given using a monoisocentric technique of multiple noncoplanar circular arches. The geometric arrangement of the plan consisted of 15 arches, with a 4 mm cone, distributed over a 110° table.

Results:

There was symptomatic and image improvement two days after radiosurgery. On CT, a reduction in ventricular dilation was observed with a reduction in the Evans index from 0.39 (initial CT) to 0.29 (CT at 15 days). In 3.0T magnetic resonance image at 3 months, we showed the third ventriculostomy. There have been no treatment failures or complications.

Conclusion:

It is possible to effectively perform the frameless radiosurgical third ventriculostomy without associated morbidity in the short term.
