Introduction

The Robert Koch Institute (RKI) managed the exchange of cross-border contact tracing data between public health authorities (PHA) in Germany and abroad during the early COVID-19 pandemic.

Aim

We describe the extent of cross-border contact tracing and its challenges.

Methods

We analysed cross-border COVID-19 contact tracing events from 3 February to 5 April 2020 using information exchanged through the European Early Warning Response System and communication with International Health Regulation national focal points. We described events by PHA, number of contacts and exposure context.

Results

The RKI processed 467 events, initiating contact to PHA 1,099 times (median = 1; interquartile range (IQR): 1–2) and sharing data on 5,099 contact persons. Of 327 (70%) events with known exposure context, the most commonly reported exposures were aircraft (n = 64; 20%), cruise ships (n = 24; 7%) and non-transport contexts (n = 210; 64%). Cruise ship and aircraft exposures generated more contacts with authorities (median = 10; IQR: 2–16, median = 4; IQR: 2–11) and more contact persons (median = 60; IQR: 9–269, median = 2; IQR: 1–3) than non-transport exposures (median = 1; IQR: 1–6 and median = 1; IQR: 1–2). The median time spent on contact tracing was highest for cruise ships: 5 days (IQR: 3–9).

Conclusion

In the COVID-19 pandemic, cross-border contact tracing is considered a critical component of the outbreak response. While only a minority of international contact tracing activities were related to exposure events in transport, they contributed substantially to the workload. The numerous communications highlight the need for fast and efficient global outbreak communication channels between PHA.

We show that the SARS-CoV-2 B.1.1.7 lineage is highly disseminated in Portugal, with the odds of B.1.1.7 proportion increasing at an estimated 89% (95% confidence interval: 83–95%) per week until week 3 2021. RT-PCR spike gene target late detection (SGTL) can constitute a useful surrogate to track B.1.1.7 spread, besides the spike gene target failure (SGTF) proxy. SGTL/SGTF samples were associated with statistically significant higher viral loads, but not with substantial shift in age distribution compared to non-SGTF/SGTL cases.

Published: March 2021

Monitoring adverse reactions following immunisation is essential, particularly for new vaccines such as those against COVID-19. We describe 20 cases of acute onset of a single supraclavicular lymphadenopathy manifesting between 24 h and 9 days after ipsilateral intramuscular administration of an mRNA-based COVID-19 vaccine, referred to our WHO Collaborating Centre for Vaccine Safety. Our results indicate that the swelling of supraclavicular lymph nodes following immunisation may constitute a benign and self-limited condition, related to a higher than recommended injection site.

The importance of polystyrene in handling and transportation of fragile equipment for safe delivery cannot be under stated. However; the post-usage has raised serious concern due to adverse effects caused by the litters on environment in blocking water-ways due to its weightlessness, release of oxides of carbon and resisting decomposition among others. This work was intended to model produced adhesive from polystyrene waste using Design Expert version 6.0.8 software and D-optimal mixture design for the responses analyses to obtain the best adhesive. Eight (8) experimental runs were generated for resin formulations with only 3 feasible, coded: R1, R4 and R7, based on 2 factorial design of experiment for resin formulations. Furthermore, 14 adhesive formulations were generated for each resin, coded: R1AD, R4AD and R7AD, that is, the formulated resin was combined with additives to produce adhesive using 3 factorial mixture designs and 4 responses, namely: viscosity, pH, percentage moisture content and percentage solid content. The responses were modeled using D-optimal mixture design: the viscosity response modeling was best fitted with quadratic model for R1AD produced adhesives, while R4AD and R7AD produced adhesives were fitted with Cubic model. The pH, percentage moisture content and percentage solid content responses were all fitted with cubic model based on the statistical and modeled data. The modeling solution was further optimized and validated for the three adhesive productions, the general selection of produced adhesive based on desirability factor and line with experimental analyses from the responses shows:  R7AD2>R4AD1>R1AD1 produced adhesives in the order of fitness.

Published: March 2021

CT (computerized tomography) is a necessary imaging modality for cancer staging and disease monitoring. Rodent models of cancer are commonly studied prior to human clinical trials, but CT in rodents can be difficult due to their small size and constant movement, which necessitates general
anesthesia. Because microCT equipment is not always available, clinical CT may be a viable alternative. Limitations of microCT and clinical CT include biosecurity, anesthesia to limit image distortion due to motion, and cost. To address several of these constraints, we created a 3D-printed
apparatus that accommodated simultaneous imaging of as many as 9 rats under gas anesthesia. Rats were anesthetized in series and placed in a 3 × 3 arrangement. To assess differences in attenuation between individual chambers and rows or columns in the device, we first imaged a standardized
phantom plug as a control. We hypothesized that attenuation of specific rat organs would not be affected regardless of the location or position in the 3D-printed device. Four organs—liver, kidney, femur, and brain—were evaluated in 9 rats. For both the phantom and kidneys, statistically
significant, but clinically negligible, effects on attenuation were noted between rows but not between columns. We attribute this finding to the absence of a top layer of the apparatus, which thus created asymmetric attenuation and beam hardening through the device. This apparatus allowed
us to successfully image 9 rats simultaneously in a clinical CT machine, with negligible effects on attenuation. Planned improvements in this apparatus include completely enclosed versions for biosecure imaging.

Una Archiva del DIY (Do It Yourself):autoedición y autogestión en una fanzinoteca feminista-queer» se centra en la creación de un archivo de colectivos, asociaciones o grupos autogestionados que produzcan ediciones de práctica feminista-queer con especial inte- rés en el fanzine y la relación música-dibujo.La creación de este archivo sería más bien la creación de un «no-archivo». Es difícil querer reunir y pretender hacer un archivo con este tipo de material que de primeras parece hui- dizo en sus estrategias y formatos. También es un material abierto a contradicciones y de replanteamientos cambiantes en  muy  cor- to plazo de tiempo. Sin embargo este tipo de iniciativas surgen para «hablar» y ser «escu- chadas». Hay muchos temas en común que unen estas manifestaciones, ideología, gustos, maneras de operar que a veces parecen ser protegidas para que su intención no sea mal interpretada al presentarlas en depende qué contextos. La intención de éste archivo es estudiar precisamente estos puntos en común y sus desencuentros para aprender de ellos.Todas  estas  dinámicas  coinciden  en  proponer nuevas fórmulas de «hacer» e incluso vivir. Parecen a veces un pasatiempo pero esta práctica conlleva dedicación, sus principios son fuertes y pretenden contagiar.
Primeras ediciones de artista en Sala d’Art Jove (2007-2011): del trabajo compartido y la edición como herramienta formativa
Authors: Sánchez Txuma
Published: March 2021

Este artículo pretende poner de relevancia las aportaciones y los trasvases producidos entre la edición de artista en arte emergente y las prácticas de edición de artista genéricas, renovadas notablemente en España a partir de la segunda parte de la década de los años dos mil. Para ello el texto se centra en la primera etapa de acercamiento a este tipo de prácticas en edición de la plataforma Sala d’Art Jove de Barcelona, principalmente a través de sus primeras ediciones desde el año 2007 en adelante. En las cuales –y en una utilización de la edición en tanto que proceso formativo–, se ensayaron diversos modelos de experimentación sobre la co-creación de contenidos; sobre las funciones de catálogo como herramienta de expansión de la exposición; así como sobre la distribución de la edición de artista fuera de la institución arte. Todas ellas, cuestiones relacionadas estrechamente con algunas transformaciones que sufrió la edición española de artista durante ese período: en la redefinición de los roles en la producción editorial, con el aumento de la transdisciplinariedad en la edición, o en la diversificación en la circulación de la edición de artista hacia territorios no estrictamente artísticos.
Anatomía doméstica de la ciudad. Disección de "Mínimos y Máximos" en la revista Arquitectura
Authors: Vilaplana Amelia
Published: March 2021

Este artículo analiza la obra de Eulàlia Grau «Mínimos y máximos», situada en el contexto de su publicación en 1977 en el número 204-205 de Arquitectura, revista del Colegio Oficial de Arquitectos de Madrid (COAM). Este volumen es el primero de la etapa postfranquista del COAM y se concibe como un documento que debe ayudar a reenfocar el rumbo de la arquitectura tras la dictadura y ante el vacío dejado por la arquitectura moderna.Los editores de la revista utilizan el proyecto en el que Grau expone el interior de seis viviendas situadas en distintas zonas de la ciudad para mostrar a sus lectores una nueva forma de entender la ciudad.Apoyándonos en los estudios de Beatriz Colomina sobre la arquitectura como medio de comunicación de masas y constatando la influencia de los cambios tecnológicos en el pensamiento arquitectónico, analizaremos cómo la revista, a través de «Mínimos y máximos», presenta los espacios domésticos como la matriz donde se gesta, de manera oculta, la realidad urbana. Asimismo, constataremos que la revista de arquitectura aparece como un espacio arquitectónico interior, campo de pruebas para la construcción de una nueva ciudad para una nueva época.

Authors: Puente Moisés
Published: March 2021

Los libros que versan sobre arquitectura suponen un género específico dentro del mundo editorial. Gustavo Gili construyó un proyecto ejemplar de publicaciones en el que lo teórico y lo visual formaban una unidad constituyendo un entramado de edición que se estableció como modelo de trabajo para este tipo de ensayos. Moisés Puente, editor en Gustavo Gili, presenta en este texto en forma de fichas, las colecciones de arquitectura publicadas por la editorial a lo largo de la segunda mitad del siglo XX. El artículo se inicia con la serie «Arquitectura y crítica» para cerrarse con la revista 2G. Se hace una reseña de autores y diseñadores que aparecen junto a las imágenes de las emblemáticas portadas de los libros en un estudio que se realiza por primera vez y que constituye un valioso documento historiográfico.

Особенности субъективной оценки пациентами с тревожными расстройствами действия анксиолитиков в зависимости от их индивидуально-типологических характеристик
Authors: Метлина Марианна Вячеславовна , Незнамов Григорий Георгиевич , Коваленок Татьяна Васильевна , Дорофеева Ольга Анатольевна
Published: March 2021

Проведен сравнительный анализ особенностей субъективной оценки типичного анксиолитика бромдигидрохлорфенилбензодиазепина (тестовая доза 1 мг и суточная — 2 мг) и атипичного — фабомотизола (тестовая доза 15 мг и суточная — 30 мг) при однократном и 14-дневном применении, терапевтического действия и эффективности препаратов у пациентов с тревожными расстройствами (генерализованными тревожными, тревожно-фобическими) в зависимости от преобладания у них индивидуально-типологических черт личности астенического или стенического полюса. Выявлено, что транквило-активирующее действие бромдигидрохлорфенилбензодиазепина преимущественно реализуется у пациентов с астеническими чертами личности, а его транквило-седативное действие — со стеническими чертами, тогда как транквило-активирующее действие фабомотизола определяется у пациентов со стеническими особенностями. Определено, что субъективная оценка пациентами действия разных анксиолитиков в тестовых дозах не различается в зависимости от личностных характеристик, а субъективная оценка курсового применения препаратов отражает особенности их клинико-фармакологического действия, по-разному реализуемые у пациентов с преобладанием астенических или стенических индивидуальных черт личности.
Дипептидные миметики NGF и BDNF: дизайн и фармакологические свойства
Authors: Тарасюк Алексей Валерьевич , Антипова Татьяна Алексеевна , Поварнина Полина Юрьевна , Гудашева Татьяна Александровна
Published: March 2021

Представлен обзор работ, посвященный созданию и изучению фармакологически активных димерных дипептидных миметиков нейротрофинов NGF и BDNF. Они были созданы в НИИ фармакологии им. В. В. Закусова по заданию академика С. Б. Середенина с использованием оригинальной стратегии, заключающейся в конструировании миметиков отдельных петель нейротрофинов при сохранении наиболее экспонированных центральных дипептидных фрагментов бета-поворотных участков этих петель и димерного строения нейротрофинов. Описывается спектр фармакологических свойств этих миметиков и его зависимость от картины активации пострецепторного сигналинга Trk-рецепторов.

Фармакологическая стимуляция гетеродимерного рецептора эритропоэтина EPOR/CD131 является одним из механизмов неспецифической нейропротекции при ряде патологичеких состояний. В данной работе мы оценили нейропротективный потенциал агонистов EPOR/CD131 при этанол-индуцированной нейродегенерации у крыс, вызванной 90-дневным вынужденным потреблением раствора этанола в возрастающих концентрациях. Было обнаружено, что эритропоэтин и PHBSP — короткий пептид, имитирующий пространственную структуру эритропоэтиновой альфа-спирали B, обладают выраженным нейропротективным эффектом, снижая когнитивный дефицит и проявления тревожности и ослабляя морфологические признаки нейродегенерации. Кроме того, анализ экспрессии мРНК методом количественной ПЦР выявил, что EPOR/CD131-опосредованная нейропротекция в данной модели связана с повышением экспрессии генов аутофагии Atg7, Becn1 и LC3A, нормализацией отношения Bax/Bcl-2, снижением экспрессии провоспалительных генов Il1b, Tnf и Ccl2 и увеличением экспрессии генов Bdnf и Ngf.
Вызванные карбахолином сокращения изолированной тонкой кишки возрастают у крысс с экспериментальным аутизмом, вызванным вальпроевой кислотой
Authors: Зиганшин Айрат Усманович , Иванова Д. В.
Published: March 2021

На модели аутизма, вызванного вальпроевой кислотой у крыс, исследовали влияние карбахолина, норэпинефрина, АТФ, 2-метилтио-АТФ и α,β-метилен АТФ на механическую активность изолированных препаратов двенадцатиперстной кишки, подвздошной кишки, семявыносящего протока и мочевого пузыря. Установили, что у крыс с экспериментальным аутизмом неселективный холиномиметик карбахолин вызывает достоверно более значительные сокращения изолированных гладких мышц как двенадцатиперстной, так и подвздошной кишки, по сравнению с контрольной группой животных. Расслабления подвздошной кишки крыс с аутизмом, вызванные агонистом P2Y-рецепторов 2-метилтио-АТФ, были более выражены, чем в контроле. Не выявлена достоверная разница в силе сокращений изолированных препаратов мочевого пузыря крыс 2 групп, вызываемых карбахолином и неселективным агонистом Р2Х-рецепторов α,β-метилен АТФ, тогда как сила сокращений семявыносящего протока, вызываемых норэпинефрином, была достоверно меньше в группе крыс с аутизмом. Установленные в этих экспериментах изменения в сократительной активности гладкомышечных органов у животных с аутизмом могут лежать в основе дисфункции как желудочно-кишечного тракта, так и мочеполовой системы, которые часто отмечаются в клинике у детей с аутизмом. Понимание патогенеза этих нарушений позволит разрабатывать подходы к их фармакологической коррекции.

Authors:   Gümüşhane University, Turkey, Arslan Adem
Published: March 2021

Family is the foundation stone of society. Education is very important for the health of the family and therefore society. A value-oriented family education program is designed to support families. The aim of this research is to determine the basic education needs of families for a value-oriented family education program. The study group of the research consists of 205 families who enrolled in 4 kindergartens in the city center of Gümüşhane in the 2020-2021 Academic Year. In the research, "Family Education Needs Assessment Form" and Personal Information Form given to families during registration were used as data collection tools. This study, which was carried out in accordance with the descriptive scanning model, was analyzed by document analysis method. Percentage and frequency distributions were used in the analysis of the data. In the research, it is important to determine which issues families attach more importance to in value-oriented family education, what they need and to create the program content accordingly. Subjects such as communication with the child, child-rearing attitudes and positive discipline methods, adjustment and behavioral problems observed in pre-school children, school-family cooperation, sexual education, teaching basic habits, books and children's books, play, preparation for primary school, television-internet and their effects on the child have been examined and it has been determined which of these the families need more in terms of family education. It is also seen that most of the families want to receive education in the morning and twice a week on weekdays. In addition, it was determined whether the educational needs of families differ according to the age of the child, the age of the mother, the age of the father, the education of the mother, the education of the father, the profession of the father, the family togetherness and the family income level.
Improving the cognitive clarity of graph models of knowledge representation and decision-making using visualization
Authors: Isaev Ruslan , Podvesovskiy Aleksandr
Published: March 2021

The article discusses the ways to improve the cognitive clarity of graph models for knowledge representation and decision making by applying visualization capabilities. Using fuzzy cognitive models as an example, it is shown that applying an approach based on visualization metaphors allows one to structure and partially formalize the task of increasing the cognitive clarity of models, breaking it down into separate easily interpreted stages, each of which contributes to providing cognitive clarity in general. The conclusion is made about the relevance of developing visualization metaphors to increase the cognitive clarity of graph models of other types.
