Delayed pericarditis in a patient with COVID-19 pneumonia: a case report
Authors: Toquica Gahona Christian C. , Raj Kavin , Shah Monarch , Sankaramangalam Kesavan , Shah Riya J. , Patel Keval V.
Published: October 2021

Background:

Severe acute respiratory syndrome has been implicated in a wide spectrum of cardiovascular complications, from mild elevation in troponins to more severe cases such as pericarditis, cardiac tamponade, and myocarditis. We present a case of delayed onset of pericarditis in a patient with COVID-19 pneumonia.

Case Presentation:

A 68-year-old woman presented to the emergency department with fever for 5 days, weakness, and fatigue. Diagnosis of COVID-19 pneumonia with superimposed bacterial infection was made. By day 22 of hospitalization, new T wave elevations were seen in cardiac monitoring and confirmation was made with EKG and diagnosis of pericarditis was made.

Initial troponin was <0.03 ng/ml and repeated one increased to 1.8 ng/ml (upper limit of normal: 0.12 ng/ml). Treatment was initiated with a high dose of aspirin 650 mg oral daily. Repeat set of troponins downtrended to normal values <0.03 ng/ml. The patient died on day 25 of illness due to worsening shock. Recent reports suggest that the development of fulminant myocarditis and severe cardiac damage experiences a 10-15-day delay following the onset of symptoms from COVID-19 pneumonia, presumably after activated T-cells and macrophages infiltrate myocardial cells. Treatment options include the use of colchicine, corticosteroids, and NSAIDs. Other interventions such as the use of azathioprine, non-human immunoglobulins, and anakinra have been described as well, but there is lack of solid evidence for their benefits.

Conclusion:

Preliminary information about the mechanisms of developing COVID-19 pericarditis may indicate that colchicine and steroids would be a reasonable treatment option. The efficacy and safety of these medications are to be elucidated.

PENDAMPINGAN IBU NIFAS DALAM PEMBERIAN ASI EKSKLUSIF
Authors: Suraida Salat Sri Yunita , Satriaawati Arisda Candra
Published: October 2021

Pemerintah memiliki kebijakan nasional tentang program terkiait pemberian ASI eksklusif yang tertuang dalam Peraturan Pemerintah Republik Indonesia Nomor: 33 Tahun 2012. Cakupan bayi diberi ASI Eksklusif di Kabupaten Sumenep Tahun 2017 sebesar 82,30 %. Namun data ini bukanlah data murni melaikan data dimana pada saat pendataan jika ada seorang bayi yang berumur 0 bulan atau 1 bulan dan bayi usia 5 bulan masih diberi ASI saja, maka pada saat itu bayi tersebut dicatat sebagai bayi yang diberikan ASI Eksklusif. Oleh karena itu angka cakupan pemberian ASI Ekslusif lebih tinggi dibandingkan dengan pemberian ASI pada usia 6 bulan murni. Rendahnya cakupan ASI Eksklusif di Kabupaten Sumenep di sebabkan oleh banyak faktor, salah satunya karena karena masih adanya kebiasaan dimasyarakat yang kurang mendukung pemberian ASI ekslusi seperti pemberian nasi atau pisang sebelum berumur 6 bulan ataupun karena ibu bekerja di  luar  rumah. Tujuan dari pelaksanaan pendampingan ibu nifas dalam pemberian ASI Eksklusif ini untuk membantu ibu nifas dalam memberikan ASI saja pada bayinya saat usia 0-6 bulan. Metode pelaksanaan PKM ini yaitu dengan melakukan pendampingan langsung pada ibu nifas yang masih memberikan ASI saja pada bayinya secara door to door sehingga dapat membantu ibu dalam mengatasi kesulitan yang dialami selama ibu memberikan ASI Ekslusif. Hasil dari pendampingan yang dilakukan selama 3 bulan ini yaitu 85% dari 13 ibu nifas yang dilakukan pendampingan, masih tetap memberikan ASI saja pada bayinya tanpa makanan tambahan lainnya. Hal ini menjukkan bahwa pelaksanaan pengabdian ini berjalan cukup
PROTECTING PATIENT’S RIGHTS IN A POST-TRADITIONAL LEGAL SYSTEM: COMPARING LATVIAN AND JAPANESE MEDICAL JURISPRUDENCE
Authors: Lytvynenko A. A.
Published: October 2021

Litigation concerning the violation of patient’s rights, which are associated with informed consent, confidentiality, right to information and medical records, as well as occasionally with end-of-life decision- making are quite frequent in common law and civil law jurisdictions, and has lasted for over a century in issues concerning malpractice, or unauthorized medical interventions and breaches of medical confidentiality. However, what could we say about medical law-related litigation in Japan? Technically, the legal system of Japan is a civil law one, but is practically post-traditional, which is reflected in extreme paternalism in healthcare and patient-physician relationships, which could be observed before the recent decades and which still has some impact on the modern Japanese medical law, despite the number of medical law-related litigation is becoming more frequent nowadays. The Japanese legislation does not have a specific “patient’s rights law” in contrast to European states, and most of the principles relating to medical malpractice derive from case law – the practice of the Supreme Court and of the lower courts. Each of the decisions strongly depends upon the factual circumstances, and the post-traditional features of the legal system may have some impact on it.

Em busca da completude: O burguês entre o cômico e o sério
Authors: Tortonese Paolo
Published: October 2021

No romance O cura de Tours, Honoré de Balzac faz com que o abade Troubert pronuncie a oração fúnebre da senhorita Gamard. O hipócrita abade tem boas razões para vangloriar as virtudes cristãs da defunta solteirona, mesmo se, em segredo, a detesta. Ele exalta desmesuradamente a vida dessa mulher, na realidade medíocre e mesquinha, e a transforma em história épica. “Le tableau de la vie étroite menée par la testatrice”, escreve Balzac, “prit des proportions monumentales”. Aqui beiramos o gênero heroico-cômico, e a desproporção entre a vida da mulher, que o leitor conhece, e a apologia feita a esta por Troubert produz um efeito cômico.

Published: October 2021

This work aims at evaluating advancement in water shut-off performance using nanocomposite hydrogel (PVP-ZnO:RF) prepared from PolyVinylPyrrolidone (PVP); used as polymer, Resorcinol-Formaldehyde (RF); used as a crosslinker and nano Zinc Oxide (ZnO); used as strength modifier and it was compared with conventional hydrogel (PVP:RF)i.e., hydrogel without ZnO nanofiller. The ZnO, used as a nanofiller in this work, was successfully bio-synthesized (i.e., green route synthesized) from plant extract (Moringa oleifera leaves) and the average size was found to be 10 nm. In this research work, the effect of ZnO nanofiller on gelation time, gel strength, thermal stability, rheological properties and water shut-off performance was systematically evaluated. On the incorporation of ZnO nanofiller, gelation time decreases but gel strength increases. The thermal stability of hydrogel was studied using a Differential Scanning Calorimeter (DSC) that depicts maximum tolerable temperature increases from 86 °C to 92 °C at 0.5 wt.% of ZnO concentration in nanocomposite hydrogel (PVP). The mechanical stability of the nanocomposite hydrogel (PVP-ZnO:RF) demonstrates that infusion of ZnO nanofiller has significantly enhanced the dynamic moduli (i.e., storage modulus (G′) and loss modulus (G″)). Moreover, the optimum results of storage modulus (G′) and loss modulus (G″) are found at 0.5 wt.% of ZnO nanofiller. The water shut-off performance in the high permeable streak, in terms of percentage reduction in permeability, was 97% and 92% for nanocomposite hydrogel (PVP-ZnO:RF) and conventional hydrogel (PVP:RF), respectively. Also, the residual resistance factor is found to be 31.31 and 12.71 for PVP-ZnO:RF and PVP:RF hydrogels. Thus, the developed nanocomposite hydrogel (PVP-ZnO:RF) may be a promising solution to excessive water production in mature oil fields.

Published: October 2021

Indeks keandalan sistem tenaga listrik dikatakan baik atau handal yaitu ketika sistem tenaga listrik dapat menjamin ketersedian energi listrik bagi konsumen. Faktor yang menentukan tingkat keandalan sistem tenaga listrik salah satunya adalah nilai dari forced outage rate (FOR). Tingkat keandalan suatu sistem pembangkit energi listrik dapat diketahui dengan cara perhitungan LOLP (Loss of Load Probability). Pembangkit Listrik Tenaga Hibrid (PLTH) Pantai Baru Pandansimo di ketahui dengan perhitungan (Loss of Load Probability) memiliki nilai LOLP sebesar 51,3627 hari/tahun. Hal ini menunjukan sistem PLTH Pantai Baru Pandansimo tidak sesuai dengan standart PLN yaitu 1 hari/tahun. Dengan permasalahan tersebut maka dibuatlah skenario perbaikan 1 dan 2 nilai keandalan LOLP. Didalam perhitungan LOLP skenario 1 yaitu menganti grup KKP dengan unit pembangkit baru dan didapatkan lah nilai LOLP sebesar 9,6908 hari/tahun. Pada skenario 2 yaitu menambah unit pembangkit baru jadi  skenario di PLTH Pantai Baru Pandansimo memiliki 4 pembangkit dan di dapatkan nilai LOLP sebesar 6,8186 hari/tahun. Pada skenario 1 dan 2 nilai nya sudah lebih baik dari pada sebelumnya tetapi belum memenuhi standart PT.PLN yaitu sebesar 1 hari/tahun
Study of the nonlinear oscillations in a mathematical model of microresonator
Authors: Пиманов Д.О.
Published: October 2021

Исследуются нелинейные колебания материальной точки, описываемые дифференциальным уравнением второго порядка, под воздействием линейной упругой силы, силы трения и силы электростатического притяжения, меняющейся с заданным периодом. Рассматриваемое уравнение представляет математическую модель микрорезонатора, в котором недеформируемая платформа с заданной массой на пружине играет роль материальной точки. В связи с этим формулируется нелинейная краевая задача с условиями периодичности, которая используется для описания нелинейных колебаний платформы. Численное исследование краевой задачи проводится методом продолжения решения по параметру на основе дифференциальных прогонок метода множественной стрельбы. В результате установлены области параметров, в которых существуют периодические решения задачи Коши для рассматриваемого дифференциального уравнения с периодом внешнего воздействия с учетом их множественности и устойчивости. Приведены примеры, в которых периодические решения переходят в хаотические колебания по сценарию Фейгенбаума через удвоение периода.

Purpose. Study of a second order non-autonomous non-linear differential equation that describes oscillations of a material point under the action of linear elastic force, frictional force and the force of electrostatic attraction which varies in time with a given frequency. The problem appears in applications of a mathematical model to MEMS resonator where a non-deformable platform with given mass attached to a spring is considered as a material point.

Methodology. In connection with the periodicity of external influence, the nonlinear boundary value problem with periodicity conditions is formulated and investigated numerically by the parameter continuation on the basis of the multiple shooting method. The stability of the obtained periodic solutions is determined using the spectrum of the monodromy matrix.

Findings. The regions of existence for model parameters in which the periodic solutions of the equation with the period of external forcing are defined taking into account their multiplicity and stability. Numerical integration has shown that the nonlinear oscillations can also exist as stable periodic oscillations with a multiple period. Furthermore, for appropriate values of parameters the chaotic oscillations appear by the Feigenbaum scenario.

Originality. The proposed method of numerical investigation allows one to effectively study nonlinear properties of the model, such as multistability, nonlinear resonance and the appearance of chaos.

Published: October 2021

Рассмотрен инфраструктурный подход обработки пространственных данных
для решения задач управления территориальным развитием, который основан на
сервис-ориентированной парадигме, стандартах OGC, web-технологиях, WPS-сервисах и геопортале.

The development of territories is a multi-dimensional and multi-aspect process,
which can be characterized by large volumes of financial, natural resources, social,
ecological and economic data. The data is highly localized and non-coordinated, which
limits its complex analysis and usage. One of the methods of large volume data processing
is information-analytical environments.
The architecture and implementation of the information-analytical environment of
the territorial development in the form of Geoportal is presented. Geoportal provides
software instruments for spatial and thematic data exchange for its users, as well as
OGC-based distributed services that deal with the data processing. Implementation of
the processing and storing of the data in the form of services located on distributed
servers allows simplifying their updating and maintenance. In addition, it allows publishing
and makes processing to be more open and controlled process.
Geoportal consists of following modules: content management system Calipso (presentation
of user interface, user management, data visualization), RDBMS PostgreSQL
with spatial data processing extension, services of relational data entry and editing,
subsystem of launching and execution of WPS-services, as well as services of spatial
data processing, deployed at the local cloud environment.
The presented article states the necessity of using the infrastructural approach when
creating the information-analytical environment for the territory management, which
is characterized by large volumes of spatial and thematical data that needs to be
processed. The data is stored in various formats and applications of service-oriented
paradigm, OGC standards, web-technologies, Geoportal and distributed WPS-services.
The developed software system was tested on a number of tasks that arise during the
territory development.

Intermediate results of the project aimed at improving methods of the detailed
analysis, assessment and prediction of global climate change impact on the regional
environment and climate are presented. New reliable interactive tools for in-depth
statistical analysis and studying climate change impact obtained in this project will
provide specialists, professionals, decision-makers and stakeholders with detailed climatic
information. The project addresses the development of a topical virtual research
environment (VRE) for the comprehensive study of ongoing and possible future climate
change. It analyses the relevant subsequent effects. Such VRE will provide full topical
informational required for studying regional economic, political and social consequences
of the global climate change. The ultimate goal of this work is a design of hardware
and software prototype supporting the topical virtual research environment for climate
and environmental monitoring and analysis of the impact of climate change on socioeconomic
processes on both local and regional scales. This VRE will integrate both
already known and new archives of climate data sets with software realizations of
traditional and advanced methods for statistical analysis of big spatial data sets.
VRE prototype will provide scientists, decision-makers and stakeholders the access
to processing resources and services for interactive analysis of geographically distributed
spatial data through a web browser. It will present the results of the analysis using
geoinformation technologies and ensure the systematization of spatial data and associated
climate information. Also, the work describes an ontological approach to this
systematization, which makes it possible to compare the semantics of meteorological
and climatic parameters used in different collections and applied problems.

Алматы. Проанализированы возможности и потребности всех участников научно-образовательного кластера для построения оптимальной архитектуры распределенной информационной системы. Приведено описание и представлены результаты реализации подсистем цифрового репозитория интегрированной распределенной библиотечной информационной системы Академгородка г. Алматы.

The purpose of the work is to create an integrated distributed library information system that allows preserving the result of intellectual activity of Kazakhstan Engineering Technological University and a number of research institutes located in the Academgorodok of Almaty in an actual form and to provide access to them based on Web technologies. The relevance of the work is related to the fact that significant amounts of information obtained as a result of research of these institutions, their continuous expansion and heterogeneity in the nature of storage and distribution, along with the lack of unified access to them create significant problems of their effective use. These problems lead to the need to find new approaches and solutions to the problems of creating a repository of information resources, their organization, means and ways to access users. In addition, the work is consistent with the goals set within the framework of the State Program “Digital Kazakhstan” for 2017-2020. The following results were obtained in the present work: 1. The analysis of the capabilities and needs of all participants of the scientificand educational cluster for building the optimal architecture of the distributed information system is carried out. 2. The model of integrated distributed library information system of Almaty Akademgorodok was developed. 3. The results of the implementation of its subsystems are presented. As a result of the conducted research, it was concluded that this system corresponds to the needs of participants in the scientific and educational cluster both in terms of information content and support for sectoral and linguistic specifics, since it solves the main tasks for these systems: providing a system for reliable long-term storage of digital (electronic) documents with preservation of all semantic and functional characteristics of source documents; ensuring “transparent” search and access of users to documents, both for familiarization and for the analysis of the facts contained therein; organization of collection of information on remote digital repositories supporting the OAI-PMH, SRW/SRU, and Z39.50 protocols.
Numerical modelling of relative intensity noise (RIN) transfer as a result of four-wave mixing in optical communication links
Authors: Федотенко Тимофей Михайлович , Беднякова Анастасия Евгеньевна
Published: October 2021

Выполнено исследование распространения сигнала в волоконной линии связи с сонаправленной накачкой. Несмотря на невозможность переноса шумов из накачки в сигнал в результате вынужденного комбинационного рассеяния (ВКР), в натурном эксперименте наблюдается деградация сигнала уже при небольших длинах распространения (порядка 5-10 км). Для исследования причин деградации сигнала построена численная модель на основе обобщенного нелинейного уравнения Шрёдингера, учитывающая дисперсию высших порядков, керровскую нелинейность и запаздывающий рамановский отклик среды. Также используется более реалистичная модель многомодового источника накачки. В результате проведенного численного анализа продемонстрировано, что в определенных условиях не только ВКР, но и четырехволновое смешение может инициировать в линиях связи процесс переноса шумов из накачки в сигнал.

It is well known that any real transmission link introduces distortions into the signal that can be either recoverable or not fully removable. The sources of such unremovable distortions leading to the loss of information are double Rayleigh scattering, amplified spontaneous emission, RIN (Relative Intensity Noise) transfer and nonlinear interactions such as four-wave mixing. In this paper we perform numerical investigation of signal propagation and RIN transfer in optical communication link with co-propagating pump. Despite the impossibility of intensity noise transfer from pump to signal due to stimulated Raman scattering (SRS), in the experiment signal degradation is observed even at small propagation lengths of 5-10 km. To find the origin of signal degradation, a numerical model is proposed based on the generalized nonlinear Schr¨odinger equation. The model takes into account the higher-order dispersion, Kerr nonlinearity, and the delayed Raman response of the medium. A more realistic model of the multimode pumping source is also employed. It is worth noting, that the most common analytical and numerical models, describing RIN transfer from pump to signal, are based on balance equations and neglects influence of dispersive and nonlinear effects. As a result of the numerical analysis, it was demonstrated that not only SRS but also four-wave mixing can initiate the process of noise transfer from pump to signal in the communication links.
Numerical investigation of self-oscillatory flows in the rotation channels with cylindrical bodies on the axis
Authors: Пинчуков В.И.
Published: October 2021

Работа посвящена поиску новых автоколебательных течений и их численному изучению. Эти поиски проводились путем расчетных исследований течений с максимальным количеством контактных разрывов и точек пересечения разрывов ударных волн с ударными волнами или ударных волн с контактными разрывами. Рассмотрены два класса течений: натекание звуковой недорасширенной струи на цилиндрическое тело, расположенное в открытой трубе, и взаимодействие сверхзвукового однородного потока с системой открытый канал вращения (с переменным сечением) цилиндрическое тело на оси. В обоих случаях найдены автоколебательные режимы. Двумерные осесимметричные уравнения сжимаемого газа решены с помощью неявной схемы РунгеКутты третьего порядка. Применяется алгебраическая турбулентная вязкость, основанная на использовании обобщенной формулы Кармана.

This paper addresses a search for new selfoscillatory compressible flows and numerical studies of these flows. These searches are carried out by computational modelling of currents with the maximum number of contact discontinuities and points of intersection of discontinuities shock waves with shock waves or shock waves with contact discontinuities. Two families of unsteady flows are considered. The first one contains flows near underextended sonic jets, impinging on cylindrical bodies placed in open tubes. The second family corresponds to interactions of uniform supersonic streams with pairs containing the open channel of rotation (with transient crossection) and a cylindrical body on the axis. Selfoscillatory regimes are found in both cases. Twodimensional axysimmetrical compressble flow equations are solved by an implicit RungeKutta scheme of the third order. Algebraic turbulent viscosity is assumed which is based on the implementation of the generalized Karman formulae. Numerical results allow concluding that unsteady flows, which take place when sonic jets impinge on a pair containing of cylinders and open tubes are typical for jets impinging on obstacles. Flows, which take place when uniform streams interact with these pairs comprise a new original class of selfoscillatory flows.
Concerto for Orchestra “The Yellow Stars” by Isaac Schwartz: In the Mirror of Ashkenazi’s Musical Culture

В статье предпринят анализ последнего произведения выдающегося петербургского композитора Исаака Шварца (1923–2009) — мемориального опуса памяти жертв Холокоста. Аргументированно доказывается, что ашкеназская культура, в том числе и музыкальная, была органичной частью всей жизни композитора. Об этом свидетельствуют сформировавшийся в детские годы этнослух И. Шварца, огромное количество песен на идиш, которые он мог играть наизусть часами и, безусловно, тематизм инструментального концерта «Желтые звезды», в котором наряду с цитатным материалом выявляются и многочисленные авторские темы, отмеченные знаком еврейской идентичности. В них прослеживаются традиции синагогальной молитвы, клезмерского музицирования, идишской народной песни. Вместе с тем в работе с тематическим материалом, с формой, с оркестровкой обнаруживается прочная связь И. Шварца с ленинградской-петербургской композиторской школой.

The article analyzes the last work of the well-known Petersburg composer Isaac Schwartz (1923–2009) which is a memorial opus in memory of the victims of the Holocaust. It is argued that the Ashkenazi musical culture was a natural part of the composer’s entire life. This is evidenced by the ethnic rumor of Schwartz formed in his childhood, a huge number of songs in Yiddish that he could play by heart for hours and, of course, the themes of the instrumental concerto “The Yellow Stars”, which demonstrates, along with quotation material, numerous author’s themes, marked by Jewish identity. They trace the traditions of synagogue prayer, klezmer music, Yiddish folk song. At the same time, the work with thematic material, with form, and with orchestration, reveals Schwartz’s tight relationship with the Leningrad-Petersburg school of composition.
Foreign Productions of Puccini’s Opera “Turandot” of Recent Decades: Chinese Images Return to Their Homeland
Authors: Хо С.
Published: October 2021

В последние годы европейское оперное наследие в Китае постепенно отклонилось от первоначального традиционного направления, став объектом вторичного творчества. Китайские режиссеры и художники решаются воплотить на национальной сцене шедевры европейского искусства, пытаясь, с одной стороны, сохранить верность сложившимся традициям, с другой — адаптировать эти произведения к индивидуальным нормам китайской культуры. Сравнивая осуществленные на рубеже XX–XXI веков версии постановок жемчужины оперного искусства «Турандот» Джакомо Пуччини, мы можем ясно увидеть как европейское «прочтение» китайской культуры в этой опере, так и позитивное влияние интеграции китайской и западной парадигм. В сравнении выявляется лучший вариант исполнения. Китайские постановки, как правило, разделены на две актерские труппы: иностранную (труппа A) и китайскую (труппа B). Принцип уважения оригинального исторического облика оперного сюжета зачастую игнорируется в западных версиях, тогда как в китайских он бережно соблюдается. Визуальный дизайн китайских постановок погружает аудиторию в поток событий, музыкальное выражение потрясает слушателей. С точки зрения эмоционального выражения чувства героев в западных версиях — прямые, открытые и страстные; для Китая же характерны скрытый смысл, завуалированность в сценарии и музыке. Таким образом, западная опера «Турандот» оказывается погруженной в стихию культуры Китая.

Along with the progress of the modern era and the efforts of Chinese artists in recent years, European operatic art in China has gradually deviated from the original traditional direction towards the secondary art. Chinese artists decide to present famous works of European art on the national stage, trying, on the one hand, to preserve its traditions, and on the other, to modernize them in accordance with the individual norms of Chinese culture. Comparing the Chinese and Western versions of the pearls of opera—Turandot from the late 1980s to 2000s, we can clearly see both penetration and development of the Chinese culture in this opera and the positive impact of integration of the Chinese and the Western paradigms. Chinese performances are generally divided into two acting troupes: a foreign troup (Troup A) and a Chinese troup (Troup B). In the comparison, the best design is highlighted. The principle of respect for the original historical image of the opera plot is often ignored in Western versions, while in Chinese it is carefully observed. The visual design of the Chinese versions immerses the audience into the sequence of events, the musical expression amazing the audience. In terms of  emotional expression, the feelings of the characters in Western versions are direct, open and passionate. China is characterized by a hidden meaning, veiled in the script and music. Thus, the Western opera “Turandot” acquires an inextricable connection with the culture of China, each version having a special historical value in art.

Background: Pyrotinib is a molecular and irreversible tyrosine kinase inhibitor independently developed in China, and its efficacy against HER2- positive breast cancer in the real world is not clear. In this study, we evaluated the efficacy and safety of pyrotinib in the treatment of HER2-positive advanced breast cancer based on real-world evidence. Materials and Methods: We designed a prospective observational study. Thirty-six patients with HER2-positive advanced breast cancer from a single medical center were included in the study from December 2018 to February 2021. All patients received the oral HER2 receptor inhibitor pyrotinib and received concurrent chemotherapy or endocrinotherapy. The follow-up endpoint is set as April 1, 2021. The primary endpoint is Objective Response Rate (ORR) and Disease Control Rate (DCR), and the secondary endpoint is Progression- Free Survival (PFS) and related side effects. Results: By the end point of follow-up, a total of 17 patients had progressed (including 6 deaths), and the progression-free survival rate was 52.78%. The median PFS was 13months (PFS range: 3-22 months). As the best response, 4 patients achieved CR, 20 patients achieved PR, 9 patients achieved SD, and 3 patient developed PD. The ORR was 66.67% and DCR was 91.67%. In the analysis, first-line pyrotinib treatment appeared to have higher ORR (88.88% vs 59.26%), but there was no significant difference. In addition, pyrotinib showed significant efficacy in patients with brain metastases, with an ORR of 42.85%. In terms of safety, the incidence of diarrhea was 80.55%, but only 4 patients had grade 3 diarrhea, which was tolerable after the drug dose was reduced; 1 patient had grade 4 neutropenia and grade 3 and thrombocytopenia, which were considered to be related to the chemotherapy drugs. The incidence of other adverse reactions was low, and all were grade 1 to 2. Conclusion: Pyrotinib combined with chemotherapy has a significant effect on HER2-positive breast cancer, and there is still a high ORR in patients who fail multiple lines of treatment. Side effects are overall controllable and safe.

Trihexyphenidyl or Artane® /Parkinane® is an anti-cholinergic drug belonging to the antimuscarinic class. It is used in the treatment of Parkinson’s disease and widely in psychiatry for the management of extrapyramidal side effects of neuroleptics. Its overdose leads to a central and peripheral anticholinergic syndrome. We report here the case of a seven-year-old Senegalese boy who developed signs of intoxication due to accidental ingestion of a high dose of trihexyphenidyl and recovered completely after administration of parenteral antipyretic, gastric lavage and supportive care in a paediatric setting.
Making Use of More Reviews Skillfully in Explaninable Recommendation Gerneration

Published: October 2021

There are a lot of reviews in the Internet, and existing explainable recommendation techniques use them. However, how to use reviews has not been so far adequately addressed.　This paper proposes a new exploiting method of reviews in explainable recommendation generation. Our new method makes use of not only reviews written but also those referred to by users. This paper adopts two state-of-the-art explainable recommendation approaches and shows how to apply our method to them. Moreover, our method in this paper considers the possibility of making use of reviews which do not provide detailed review utilization. Our proposal can be applied to different explainable recommendation approaches, which is shown by adopting the two approaches, with reviews that do not necessarily provide their detailed utilization data. The evaluation with using Amazon reviews shows an improvement of the two explainable recommendation approaches. Our proposal is the first attempt to make use of reviews which are written or referred to by users in generating explainable recommendation. Particularly, this study does not suppose that reviews provide their detailed utilization data.
On the extremal points of the Lambda polytopes and classical simulation of quantum computation with magic states

We investigate the $\Lambda$-polytopes, a convex-linear structure recently defined and applied to the classical simulation of quantum computation with magic states by sampling. There is one such polytope, $\Lambda_n$, for every number $n$ of qubits. We establish two properties of the family $\{\Lambda_n, n\in \mathbb{N}\}$, namely (i) Any extremal point (vertex) $A_\alpha \in \Lambda_m$ can be used to construct vertices in $\Lambda_n$, for all $n>m$. (ii) For vertices obtained through this mapping, the classical simulation of quantum computation with magic states can be efficiently reduced to the classical simulation based on the preimage $A_\alpha$. In addition, we describe a new class of vertices in $\Lambda_2$ which is outside the known classification. While the hardness of classical simulation remains an open problem for most extremal points of $\Lambda_n$, the above results extend efficient classical simulation of quantum computations beyond the presently known range.
