Data synthesis via differentially private markov random fields
Authors: Cai Kuntai , Lei Xiaoyu , Wei Jianxin , Xiao Xiaokui
Published: October 2021

This paper studies the synthesis of high-dimensional datasets with differential privacy (DP). The state-of-the-art solution addresses this problem by first generating a set
M
of noisy low-dimensional marginals of the input data
D
, and then use them to approximate the data distribution in
D
for synthetic data generation. However, it imposes several constraints on
M
that considerably limits the choices of marginals. This makes it difficult to capture all important correlations among attributes, which in turn degrades the quality of the resulting synthetic data.

To address the above deficiency, we propose PrivMRF, a method that (i) also utilizes a set
M
of low-dimensional marginals for synthesizing high-dimensional data with DP, but (ii) provides a high degree of flexibility in the choices of marginals. The key idea of PrivMRF is to select an appropriate
M
to construct a
Markov random field (MRF)
that models the correlations among the attributes in the input data, and then use the MRF for data synthesis. Experimental results on four benchmark datasets show that PrivMRF consistently outperforms the state of the art in terms of the accuracy of counting queries and classification tasks conducted on the synthetic data generated.
Real-world trajectory sharing with local differential privacy
Authors: Cunningham Teddy , Cormode Graham , Ferhatosmanoglu Hakan , Srivastava Divesh
Published: October 2021

Sharing trajectories is beneficial for many real-world applications, such as managing disease spread through contact tracing and tailoring public services to a population's travel patterns. However, public concern over privacy and data protection has limited the extent to which this data is shared. Local differential privacy enables data sharing in which users share a perturbed version of their data, but existing mechanisms fail to incorporate user-independent public knowledge (e.g., business locations and opening times, public transport schedules, geo-located tweets). This limitation makes mechanisms too restrictive, gives unrealistic outputs, and ultimately leads to low practical utility. To address these concerns, we propose a local differentially private mechanism that is based on perturbing hierarchically-structured, overlapping
n
-grams (i.e., contiguous subsequences of length
n
) of trajectory data. Our mechanism uses a multi-dimensional hierarchy over publicly available external knowledge of real-world places of interest to improve the realism and utility of the perturbed, shared trajectories. Importantly, including real-world public data does not negatively affect privacy or efficiency. Our experiments, using real-world data and a range of queries, each with real-world application analogues, demonstrate the superiority of our approach over a range of alternative methods.
PolyFrame

Published: October 2021

In the last few years, the field of data science has been growing rapidly as various businesses have adopted statistical and machine learning techniques to empower their decision-making and applications. Scaling data analyses to large volumes of data requires the utilization of distributed frameworks. This can lead to serious technical challenges for data analysts and reduce their productivity. AFrame, a data analytics library, is implemented as a layer on top of Apache AsterixDB, addressing these issues by providing the data scientists' familiar interface, Pandas Dataframe, and transparently scaling out the evaluation of analytical operations through a Big Data management system. While AFrame is able to leverage data management facilities (e.g., indexes and query optimization) and allows users to interact with a large volume of data, the initial version only generated SQL++ queries and only operated against AsterixDB. In this work, we describe a new design that retargets AFrame's incremental query formation to other query-based database systems, making it more flexible for deployment against other data management systems with composable query languages.
TQEL

Published: October 2021

Social media analysis over blogs (such as tweets) often requires determining top-k mentions of a certain category (e.g., movies) in a collection (e.g., tweets collected over a given day). Such queries require entity linking (EL) function to be executed that is often expensive. We propose TQEL, a framework that minimizes the joint cost of EL calls and top-k query processing. The paper presents two variants - TQEL-exact and TQEL-approximate that retrieve the exact / approximate top-k results. TQEL-approximate, using a weaker stopping condition, achieves significantly improved performance (with the fraction of the cost of TQEL-exact) while providing strong probabilistic guarantees (over 2 orders of magnitude lower EL calls with 95% confidence threshold compared to TQEL-exact). TQEL-exact itself is orders of magnitude better compared to a naive approach that calls EL functions on the entire dataset.
microempresarios mexicanos informales más visibles en 2016, una cuestión de escape y exclusión
Authors: Saavedra García María Luisa , Palacios Duarte Pablo Daniel
Published: October 2021

El objetivo de esta investigación consistió en brindar un panorama de las características de los jefes de familia mexicanos que se encuentran en el sector microempresarial informal, así como determinar el rendimiento de su trabajo, con la finalidad de conocer qué es lo que los motiva a la informalidad: el escape o la exclusión. Se utilizó una muestra de 51 471 trabajadores formales y 3424 trabajadores informales aplicando un modelo de Heckit, con datos del año 2016. Los hallazgos muestran que el ingreso que reciben los trabajadores informales es superior y que se dedican a esta actividad por escape; es decir, existen factores, como el número de horas que dedican al trabajo, la remuneración por el tiempo empleado y el mantener, conservar y equilibrar las relaciones familiares, que motivan la informalidad, especialmente en la mujer. También, el nivel educativo, aunado a la baja calidad del empleo, limitan la migración al sector formal.
Wpływ transglutaminazy na objętość właściwą i porowatość miękiszu bezglutenowego chleba gryczanego
Authors: Sadowska Aleksandra , Diowksz Anna
Published: October 2021

Pieczywo to podstawowy składnik codziennej diety. Dla chorych na celiakię tym podstawowym produktem jest chleb bezglutenowy, który w stosunku do pieczywa tradycyjnego charakteryzuje się mniejszą wartością odżywczą. Poszukuje się więc sposobów, aby tę wartość zwiększyć, a jednym z kierunków badań jest poprawa parametrów jakościowych pieczywa bezglutenowego dzięki wykorzystaniu preparatów enzymatycznych. Celem przeprowadzonych badań była ocena wpływu dodatku transglutaminazy (TG) o aktywności 5, 10, 15 U/100 g mieszanki, zawierającej w równych ilościach mąkę gryczaną i bezglutenową skrobię pszenną, na parametry jakościowe chleba bezglutenowego, w tym objętość właściwą pieczywa i porowatość miękiszu. Włączenie preparatu enzymatycznego do receptury ciasta wpłynęło na zmianę podstawowych parametrów wypiekowych pieczywa gryczanego – zwiększyła się wilgotność miękiszu chleba, a zmniejszyła się strata piecowa. Dodatek TG wywarł także korzystny wpływ na objętość właściwą pieczywa. Zaobserwowano istotne różnice już przy dawce 5 U TG/100 g mieszanki. Poprawiła się struktura porowata miękiszu – znacznie zwiększyła się liczba porów przypadająca na 10 cm2 powierzchni kromki, stały się one cienkościenne i równomiernie rozmieszczone. Jednocześnie stwierdzono, że zwiększenie dawki enzymu do 15 U/100 g mieszanki nie było korzystne. W ocenie sensorycznej wskazano na dobrą akceptację pieczywa gryczanego. Również pod tym względem szczególnie wysoko oceniono próbę zawierającą 5 U TG/100 g mieszanki. Paneliści docenili wygląd przypominający konwencjonalne pieczywo oraz charakterystyczny dla ziarniaków gryki smak i zapach, co wyróżnia pieczywo gryczane wśród innych produktów bezglutenowych.

mundo no es dueño en su propia casa: hacia una teoría-narrativa y alternativa de la globalización
Authors: García Escobar Rubén Darío
Published: October 2021

Dos hechos caracterizan la globalización: de un lado, el incremento de interacciones sociales ha dado lugar a un nuevo ámbito social que se caracteriza por tener sus propias instituciones e imaginarios sociales, los cuales se superponen o entran en conflicto con aquellos que son propios de sociedades particulares; de otro lado, este nuevo ámbito social cuenta con sus propias clausuras, tendencia de lo social a explicarse a partir de sí misma. Juntos hacen parte de un mismo fenómeno por el cual el planeta entero ha participado de lo que en este trabajo se denomina clausura mundánica, proceso mediante el cual el mundo deviene sujeto-objeto-contenedor, llevándolo a ser un imaginario incuestionable. Precisamente porque nadie duda del mundo es necesario hacerlo y analizar cómo se manifiesta, qué efecto tiene en la experiencia de vivir en un ámbito social global, unitario e interdependiente. Para ello el artículo se encuentra dividido en tres partes: primero, análisis de la mundialización como el proceso por el cual el mundo se hace sujeto de su propio devenir; segundo, análisis de la globalización como el proceso mediante el cual el mundo logra coincidir con la tierra o consigo mismo; tercero, siendo los dos momentos constitutivos de la clausura mundánica, globalización y mundialización han derivado en una tiranía de mundo que no es más que la situación de heteronomía a la que conduce el mundo en la forma de una alienación frente a los entes y el tiempo. En el artículo se exploran las propuestas que caracterizaron el ánimo intelectivo de comienzos del siglo XX y, también, se acudirá a ciertos aportes de la Escuela Inglesa de Relaciones Internacionales por ayudar a enriquecer esta discusión. El objetivo de esta indagación es poder elucidar ciertos elementos que permitan construir una narrativa alternativa que pueda ayudar a comprender mejor la experiencia de vivir en un mundo en el cual el neoliberalismo se ha hecho una razón global.
El islam en la globalización LGBTQ: una aproximación queer a las Relaciones Internacionales
Authors: Fernández Daniel Ahmed
Published: October 2021

El objetivo de este artículo es la elaboración de un estado de la cuestión sobre el islam en el marco de la globalización LGBTQ atendiendo a las formas históricas específicas en que se constituye el conocimiento vinculado a cada uno de estos dos ejes, además de las prácticas sociales, las formas de subjetividad y las relaciones de poder inherentes a tales conocimientos desde el punto de vista de las estrategias de vigilancia, control y prohibición. Este trabajo se ha llevado a cabo a través del análisis de las dos posiciones hegemónicas de oposición entre islam y diversidad sexual y de género —una, de LGBTQfobia islamizada, la otra, de islamofobia queerizada— sobre la base de las cuales las personas musulmanas, incluyendo las LGBTQ, son subalternizadas, discriminadas y criminalizadas en la actualidad, tanto en Occidente como en los países de mayoría musulmana. Este trabajo propone un enfoque queer a través del cual poner en conversación las Relaciones Internacionales y los estudios transnacionales y/o globales queer en torno a las conexiones contemporáneas entre raza, religión, clase, género, sexualidad, estado y nación desde un compromiso de denuncia contrahegemónica. Con el fin de profundizar en todas estas cuestiones el artículo está estructurado en cuatro secciones: introducción, enfoque teórico-metodológico, dos epígrafes de desarrollo y conclusiones. El apartado introductorio clarifica, desde una perspectiva antropológica crítica, la pertinencia de la reconceptualización de la religión como categoría de análisis a la hora de abordar el estudio del islam. El primer epígrafe de desarrollo, centrado en la LGBTQfobia islamizada, analiza los múltiples elementos geográficos, culturales, sociopolíticos, económicos y legislativos que componen esta problemática. El segundo epígrafe de desarrollo, dedicado a la islamofobia queerizada, profundiza en el ensamblaje del homonacionalismo y constata la consolidación de lo LGBTQ en tanto que requisito de acceso a la ciudadanía y como marcador civilizacional de la alteridad musulmana. Finalmente, en el apartado de conclusiones, se presenta un resumen de los resultados del trabajo y se pincelan algunas posibles futuras líneas de investigación.
Land Rights and Health Outcomes in American Indian/Alaska Native Children
Authors: Burns Joseph , Angelino Alessandra C. , Lewis Kyna , Gotcsik Marah E. , Bell Ronny A. , Bell Joseph , Empey Allison
Published: October 2021

American Indian and Alaska Native (AI/AN) land rights, sovereignty conflicts, and health outcomes have been significantly influenced by settler colonialism. This principle has driven the numerous relocations and forced assimilation of AI/AN children as well as the claiming of AI/AN lands across the United States. As tribes across the country begin to reclaim these lands and others continue to struggle for sovereignty, it is imperative to recognize that land rights are a determinant of health in AI/AN children. Aside from the demonstrated biological risks of environmental health injustices including exposure to air pollution, heavy metals, and lack of running water, AI/AN children must also face the challenges of historical trauma, the Missing and Murdered Indigenous Peoples crisis, and health care inequity based on land allocation. Although there is an undeniable relationship between land rights and the health of AI/AN children, there is a need for extensive research into the impacts of land rights and recognition of sovereignty on the health of AI/AN children. In this article we aim to summarize existing evidence describing the impact of these factors on the health of AI/AN children and provide strateg ies that can help pediatricians care and advocate for this population.

Published: October 2021

A saúde mental dos profissionais de saúde da linha de frente durante a pandemia da Doença Coronavírus-2019 (COVID-19) está relacionada a uma percepção qualitativa de risco sobre a doença, segundo a Teoria do Traço Difuso. Uma pesquisa de levantamento foi realizada com 134 profissionais de saúde da linha de frente em um município da região metropolitana do Rio Grande do Sul. Os participantes responderam a um questionário online sobre percepção de risco e a Clinical Outcome Routine Evaluation - Outcome Measure. Análises de regressão linear corroboraram a literatura, indicando que a percepção qualitativa do risco estava relacionada a menor sofrimento psicológico e uma avaliação quantitativa, a maior sofrimento. Os resultados demonstraram a importância da Teoria do Traço Difuso para compreensão dos riscos associados ao sofrimento mental (potencialmente clínico) de profissionais de saúde durante a pandemia.

Referential and non-referential (im)politeness
Authors: Cook Haruko Minegishi
Published: October 2021

Honorifics are non-referential indices that are generally understood as polite linguistic forms. Why do speakers use honorifics when they express a face-attacking referential message? Brown and Levinson’s politeness theory (1987) explains that the use of honorifics is a negative politeness strategy that mitigates an FTA (face-threatening act). However, the reason why honorifics co-occur with a face-attack probably involves more than mitigating an FTA. This article deals with a case of institutional impoliteness by examining a Japanese company’s new employee orientation discourse. This is a context in which impoliteness is ideologically legitimised and often deployed. At the same time, the goal of the orientation is to train new employees to behave in an extremely polite manner. By qualitatively analysing the speech of the trainer of a new employee orientation, this article concludes that the trainer’s use of honorifics while attacking the positive face of the new employees is a way of resolving the conflicting demands of a Japanese company. This article contributes to (im)politeness research in that it points to the importance of distinguishing referential and non-referential (im)politeness.

Authors: Labella-Sánchez Natalia , Viana da Rosa Francyelle
Published: October 2021

O presente trabalho tem como objetivo analisar provas de espanhol do Exame Nacional do Ensino Médio (ENEM) de modo a qualificar o planejamento e a produção de materiais didáticos para as aulas de Espanhol em Pré-Universitários Populares, espaços educativos que têm como finalidade principal a democratização do acesso ao ensino superior. A reflexão sobre tal contexto de ensino apoiou-se nos pressupostos freirianos referentes à Educação Popular (Freire, 2017), relacionando-os ao conceito bakhtiniano de dialogismo e a relação intrínseca entre língua e vida. Como aporte teórico para a análise das provas de espanhol, também utilizamos os conceitos bakhtinianos de dialogismo (Bakhtin, 2016) e os pressupostos teórico-metodológicos relacionados às capacidades de linguagem (Dolz; Schneuwly, 1998; 2010), ambos refletidos nos procedimentos metodológicos adotados. Os resultados evidenciaram a necessidade de preparar um material voltado para a formação consciente e cidadã dos estudantes e para a formação de leitores capazes de mobilizar conhecimentos de mundo e de compreender os contextos de produção dos textos, uma vez que a capacidade de ação é um dos conhecimentos mais mobilizados para a solução das questões dos exames.

Published: October 2021

Resumo Objetivo compreender as percepções de profissionais da educação sobre as violências contra crianças e adolescentes em contexto de pandemia pela Covid-19. Método pesquisa com abordagem qualitativa, ancorada no Paradigma Complexo, realizada com sete profissionais da educação entre setembro e outubro de 2020. A coleta de dados se deu por entrevistas semiestruturadas realizadas em plataforma virtual gratuita, sendo os dados analisados tematicamente. Resultados emergiram dois temas finais “Violência e pandemia” e “(Não) percepção de possibilidades de atuação”. A violência contra crianças e adolescentes é vislumbrada como fenômeno multidimensional pelos participantes. Pelas especificidades de maior ocorrência nas famílias, as alterações da vida impostas pela pandemia, em especial, o afastamento escolar, podem implicar no aumento de casos e maior dificuldade para identificação de violências contra essa população. Os impactos à saúde mental de crianças e adolescentes nesse período foi reforçado. Conclusão e implicações para a prática apesar da compreensão de maior exposição às violências durante a pandemia, os profissionais não conseguiram propor estratégias para enfrentamento. Novos estudos sobre o tema com diferentes atores envolvidos, e articulação intersetorial para enfrentamento do fenômeno, são necessários.
Influence of backfill type on the load-bearing performance of GRS bridge abutments
Authors: Hatami K. , Boutin J.
Published: October 2021

The influence of backfill type and material properties on the performance of field-scale geosynthetic reinforced soil (GRS) abutment models is investigated. Two alternative types of backfill as recommended in the Federal Highway Administration (FHWA) guidelines (called open-graded and well-graded) were used to build two field-scale model abutments and compare their load-bearing performance under a loading beam. Results are presented and discussed relative to the loading beam settlement, facing deformation and reinforcement strains. The well-graded backfill was found to result in smaller beam settlements and facing lateral deformations, especially at smaller loads that were comparable to service load levels. However, it was significantly faster and easier to compact the open-graded aggregate to the unit weight recommended in the guidelines. Nevertheless, performances of both abutment models were found to be satisfactory relative to the limiting requirements on the beam settlement and facing deformations at service load levels.
Gender and Stature Estimate Based on Facial Measurements: an Anthropometric Study in Southwest Iranian Population
Authors: Eftekhari Moghadam Alireza , Absalan Forouzan , Pirzad Kimia , Zahedi Atefeh
Published: October 2021

This study was aimed to evaluate the facial dimensions and their relation with gender and stature in the Iranian southwest population. A cross-sectional study was conducted among 300 southwest Iranian cases age 20-50 years (150 males and 150 females). Studied variables through physical anthropometry in both genders were Upper facial height (UFH), Total facial height (TFH), Facial Height (FH), Facial Width (FW), and intercanthal width (IC) using a standard sliding caliper and Collis. Regarding the sex and age of the individuals, general descriptive analysis of facial dimensions was determined. All measurements, except TFH and FH, were different between men and women (p≤ 0.01). In male subjects, the Pearson’s correlation coefficient (r) revealed that IC (0.72 ⃰ ⃰ ), FW (0.58 ⃰ ⃰ ) and UFH (0.18 ⃰⃰ ⃰ ) parameters had a positive correlation with stature. In the female group, none of the facial parameters had a significant correlation with stature. Regarding the value of each facial diameter in discriminating male and female stature and gender, the highest discriminative value was specified to the FW (cutoff: 11.89, sensitivity: 89%, specificity: 11%) and IC (cutoff: 2.26, sensitivity: 98%, specificity: 0.04%) respectively. This study showed a significant association of some facial measurements with stature and gender in the southwest Iranian population. IC and FW had the most diagnostic value for gender and stature definition. It is shown a useful reference for the adult southwest Iranian population for facial recognition and that the subject’s sex should be considered during body identification procedures.

Preparation of oleylethylene glycol-sreptavidin surfaces for SPR v2
Authors: Fernig Dave , Su Dunhao
Published: October 2021

Surface plasmon resonance uses gold surfaces for sensing. Manufacturers provide a range of pre-functionalised surfaces, but these are often prone to non-specific binding problems. In other surface science sensing techniques a range of surface functionalisation approaches have been described. Here, the preparation of a self-assembled monolayer (SAM) of a thiolated oleyl ethylene glycol, incorporating a defined mole % of biotinylated ligands , on a gold surface is described. This allows the formation of a streptavidin layer on the SAM with control over the average surface coverage of streptavidin. Biotinylated ligands can then be immobilised on the streptavidin. Such surfaces have proved to be very resistant to non-specific binding and they are easily implemented on the sensor surfaces of commercial (surface plasmon resonance) SPR instruments. This is adapted from a published method: Migliorini, E. et al. Well-defined biomimetic surfaces to characterize glycosaminoglycan-mediated interactions on the molecular, supramolecular and cellular levels.

Prerequisites for Accepting the Digital Educational Environment in New Cultural and Historical Conditions
Authors: Radchikova N.P. , Odintsova M. , Sorokova M.G.
Published: October 2021

According to cultural historical activity theory motivation, adaptability, study-related experience (“perezhivanie”), and moral codes may be considered as prerequisites for Digital educational environment (DEE) acceptance. To measure the attitudes towards DEE a Scale for Assessing University Digital Edu¬cational Environment was used (AUDEE Scale by M. Sorokova, M. Odintsova, and N. Radchikova). Aca¬demic motivation was evaluated by “Academic Motivation Scales” Questionnaire (by T. Gordeeva, O. Sy¬chev, and E. Osin). Study-related experiences were measured by Activity-Related Experiences Assessment technique (AREA) developed by D. Leontiev and his colleagues. Moral behavior was evaluated with the help of Moral Disengagement Questionnaire (MD-24) adapted by Y. Ledovaya and her colleagues. Stu¬dents’ adaptability was accessed by a questionnaire developed by T. Dubovitskaya and A. Krylova. 406 stu¬dents of Moscow State University of Psychology and Education took part in the investigation (90,1% fe¬male). The average age was 28,7±9,6 years (median = 24 years) varying from 19 to 72 years. The results showed that it is possible to distinguish two groups based on the results of AUDEE scale: Acceptance group and Resistance group. Acceptance group has higher scores in almost all motivation indicators, study-related experiences of pleasure and meaning, adaptability to educational activities, and lower scores in five out of seven moral disengagement strategies. Statistical analysis (classification trees) showed that motiva¬tion (both external and internal) and study-related experience are key resources for the DEE acceptance.
Effect of FOXP3 gene variants on the immune-active HBV and inactive HBV phases
Authors: AKGÖLLÜ Ersin
Published: October 2021

Purpose: FOXP3 gene rs2232365 A/G and the rs3761548 A/C polymorphisms were associated with immune system-related diseases such as Hepatitis B virus (HBV) infection. The function of Treg cells which act as immune-suppressors in the control of HBV-related liver inflammation may be affected by these polymorphisms. The aim of the present study was to evaluate the association between these polymorphisms with HBV infection phases.

Materials and Methods: The current study examined the FOXP3 gene polymorphisms in 116 patients with immune-active hepatitis B phase and in 116 individuals with inactive hepatitis B phase by a real-time polymerase chain reaction (RT-PCR).

Results: In females, the A allele and AA genotype of rs2232365 polymorphism was not statistically significant although it increased 1.28- and 1.67-fold immune-active HBV risk. Although the G allele of rs2232365 polymorphism increased 1.69-fold immune active HBV risk, it was not statistically significant in males, either. Likewise, the rs3761548 polymorphism could not reach a statistically significant value in males and females, either.

Conclusion: This research is to demonstrate the relation between phases of HBV infection and polymorphisms of the FOXP3 gene in the Turkish population. The results of this study showed that there is no effect of these polymorphisms on the immune-active phase of HBV, even though it increased immune-active HBV.
«MONGOLIAN QUESTION» AT THE YALTA CONFERENCE (1945)
Authors:   Dorzhi Banzarov Buryat State University, Galdan A. Galdanov
Published: October 2021

The article is devoted to the historical significance of the Yalta (Crimea) Conference held from 4 to 11 February 1945 for the history of Mongolia. The struggle of the Mongolian People’s Republic for independence and its participa-tion in World War II are the subject of constant study of Russian and Mongolian his-toriography. However, as a rule, these events are considered partially and are not an independent subject of research. The process of restoring the sovereignty of Mongo-lia has gone a long grassroots and difficult way. In 1911 Mongolia declared itself a sovereign state, and after that for almost fifty years it defended the right to be an in-dependent state, primarily in front of China, which remained the main sound-forming opponent of Mongolia’s sovereignty when it was reunited. China’s policy remained unchanged even after the military balance on this side changed in favor of the USSR. It was only after World War II that China officially recognized the independence of the Mongol People’s Republic. It is also worth noting the position of the allies of the USSR on the anti-Hitler coali-tion represented by the United States and the Great Britain on this question. Because of the strategic plans, the United States and the United Kingdom did not oppose it. But it should be emphasized that the United States carefully studied this question up to the trip of the American delegation to Mongolia in 1944. In the conclusion we have emphasized the important role of the Yalta (Crimea) Conference for Mongolia.
Presence of women in futsal. A systematic review
Authors: Sanmiguel-Rodríguez Alberto
Published: October 2021

Futsal is one of the sports that has been gaining in number of practitioners worldwide. Among the groups in which the practice has grown in recent decades, women stand out. Thus, the objective of this review is to offer a vision of the most recent scientific publications in relation to the presence of women in futsal. For this, a systematic review was carried out from 2015 to 2020, searching with the terms of the UNESCO Thesaurus: “futsal” and “woman” in the Scopus and Dialnet databases, allowing the selection of original articles (experimental, descriptive, quasi -experimental and / or case studies) that included information on this line of research. A total of 381 articles were found, although after applying the inclusion criteria of the review they were reduced to 27 articles. These publications were divided into three main categories: 1) Research related to conditioning factors of training and competition in women, 2) Research related to injuries and other psychological variables in women and 3) Other topics investigated; doing a discussion about each of these categories. In conclusion, this systematic review makes it possible to quickly and easily observe the analysis of women’s futsal research within the international context in recent years, as well as to identify the most relevant scientific issues today. Thus, there is a scarce number of publications on the presence of women in futsal in all the topics of study, and therefore, it is necessary to cover with greater scientific contribution given the great boom, extension and popularity that has been acquiring the figure of the woman in this sport.

The objective of this work is to analyze the reliability and validity of the new inertial measurement unit (IMU) PUSHTM Band 2.0 to measure barbell velocity. Six healthy males (24.83±3.71years; 69.88±8.36kg; 175.92±4.5cm) participated in this study and performed several sets on the bench press. Barbell concentric mean (MV) and peak (PV) velocity were recorded with a LT and the IMU. Pearson correlation coefficient shows a very high relationship for MV (r = 0.97; SEE: 0.08 m/s; 95%CI: 0.95-0.98; p< 0.001) and PV (r = 0.97; SEE: 0.13 m/s; 95%CI: 0.96-0.98; p< 0.001). There was a very high agreement for the values of MV and PV (MV: ICC = 0.945, CI = 0.834–0.974, α = 0.981; PV: ICC = 0.926, CI = 0.708–0.969, α = 0.977). Paired sample t-test revealed systematic bias for MV (p< 0.001; mean difference between instruments = 0.06 ± 0.09 m/s) and PV (p< 0.001; mean difference between instruments = 0.15 ± 0.18 m/s). Bland-Altman plots showed almost trivial and moderate relationships for MV (r2 = 0.1) and PV (r2 = 0.37). In conclusion, the PUSHTM Band 2.0 was proven to be a valid alternative for measuring barbell velocity in the bench press.

Introduction: The possibility of performing intense workouts without falling into states of chronic fatigue stimulates the use of devices that improve muscular and hormonal functionality in athletes. The Elevation Training Mask (Training Mask LLC) (ETM) allows the application of hypoxia during exercise. The ETM is integrated into training routines increasing the physical stimulus to improve performance. Objective: We evaluated the impact of ETM on Workouts of the Day (WODs), muscular and hormonal behavior in Crossfit® athletes. Material and method: Prospective cohort study. During 12 weeks 20 Crossfit® athletes trained 60 minutes 3 days a week were randomly divided into 2 groups, control group (CG) (n=10) and ETM group (EG) (n=10) applying an additional progressive simulated altitude between 914 and 2743 meters. WODs (press, squat, deadlift, total CF and grace), macular markers: lactate dehydrogenase (LDH); creatine kinase (CK); myoglobin (Mb) and hormones: testosterone (T); cortisol (C), were evaluated at 2 time points of the study: day 1 (T1) and day 84 (T2). Results: All WODs and parameters LDH, CK, Mb, T and C showed no significant difference (p>0.05) in the time group interaction. In EG, a substantially lower percentage change (Δ) between T1 and T2 was observed in Mb (-16.01±25.82%), CK (6.16±26.05%) and C (-0.18±4.01%) than in CG (Mb: -094±4.39%; CK: 17.98±27.19%; C: 4.56±3.44%). The Δ T1-T2 in the WODs were similar. Conclusion: After 12 weeks of training under simulated hypoxia conditions with ETM there are no improvements in athletic performance assessed by WODs. However, the greater tendency to decrease Mb, CK and C, after using ETM, could stimulate recovery and indicate a lower muscle catabolism of the Crossfit® athlete in the long term.

Authors: A. Mary Stephen , P. Jayasri , J. Harigaravelu P.
Published: October 2021

Internuclear ophthalmoplegia is characterised by restricted ocular motility in lateral gaze in which the affected eye shows impairment of adduction and it results from damage to medial longitudinal fasciculus (MLF). Wall-eyed bilateral internuclear ophthalmoplegia (WEBINO) is an extremely rare neurological manifestation which has typical signs including primary gaze exotropia, vertical gaze palsy, ptosis, abducting nystagmus. The common and serious etiological factor is cerebrovascular accident involving the vessels supplying MLF and many cases have life threatening associated neurological impairment. In this case report we have discussed about a gentleman who presented with bilateral ptosis, primary gaze exotropia and headache. Patient found to have vertical gaze palsy and abducting nystagmus on examination. Computed tomography (CT) imaging shows infarct in pontine region and CT angiography revealed basilar artery occlusion supplying region of pons with involvement of posterior cerebral artery. Patient treated with antiplatelet and diplopia managed. Patient showed improvement on subsequent follow-up visits.

Authors: Sheth Sharad , Abraham Abi , Abraham Georgi , Kumar Sampath
Published: October 2021

Renal diseases like chronic kidney disease (CKD) and end-stage renal disease (ESRD) are a major healthcare burden in developing countries like India. Kidney transplantation is considered to be the most viable treatment option for such patients. In comparison to dialysis, renal transplantation is associated with reduced mortality and improved quality of life. However, a major challenge experienced in transplant procedures is transplant rejection. Four virtual advisory board meetings involving 30 nephrology experts were conducted to discuss the current therapeutic landscape of kidney transplant rejection in India and subsequent practice-based insights of the experts were garnered. The experts concurred on the need for appropriate screening including immunological profiling, diagnosis, and management of candidates for transplantation. While immunosuppressive therapy and strategies like plasmapheresis, intravenous immunoglobulin, corticosteroids, and rituximab have been well established in the treatment of transplant rejection, novel and emerging treatment modalities like interleukin-6 antagonists, imlifidase or complement inhibitors have shown promise and should be considered. Increased awareness among physicians about the development of newer immunosuppressive regimens with lower side effects that may improve long-term outcomes of kidney transplantation is warranted.

Authors: Chandak R. M. , Sharma Mohit , Jha Amrit
Published: October 2021

Background: Proximal humeral fracture is 3rd most common fracture in elderly population. Selection of appropriate implant is always challenging to get optimum results in these osteoporotic bones. Though locking plates are gold standard, major complications range from 9% to 36%. To study clinical and radiological outcome of J nail technique for Neer’s three or four part proximal humeral fractures in patients more than 60 years age.

Methods: We retrospectively studied 60 patients of 3 or 4 part proximal humeral fractures, >60 years of age treated with J nail technique from the period of 2015 to 2017. J nails were made using 2 mm 12 inches blunt tip Lambrinudi wires. At final follow-up, clinical outcome was assessed using constant score and radiological evaluation was done according to the Bahr criteria.

Results: The mean constant score at final follow-up was 90. The postoperative reduction was excellent in 98% of patients and remained excellent in 90%. The mean postoperative neck shaft angle was 135.0° and final neck shaft angle was 131.4°. No deep infection was seen. No avascular necrosis of humeral head was found till follow up to 2 years.

Conclusions: Our study suggests that the functional and radiological outcomes obtained with J nailing are excellent and similar to locking plates and percutaneous Kirschner wire fixation with many other advantages of being simple, minimally invasive, avoiding muscle transfixation and no pin site infections.
Lateral distal tibial locking compression plate fixation through single lateral incision technique is biologically superior and mechanically equivalent alternative to medial plate fixation for lower third tibia-fibula fractures
Authors: Borade Amrut , Hajgude Gitkumar
Published: October 2021

Background: A number of surgical options for management of distal tibia fractures makes scenario confusing and available techniques are associated with complications. Recently lateral plating of tibia has shown good promise. To compare results between medial and lateral distal tibial locking compression plate for treatment of distal third tibia fractures

Methods: Prospective clinical study was carried out among 24 patients presenting with distal third tibia fractures. Patients were randomized into two groups of 12 each. One group was allocated into medial distal tibial LCP and second group was allocated into lateral distal tibial LCP. In first group, approach taken was medial or anteromedial while in second group, approach taken was lateral. Follow up was done for six months after surgery.

Results: There were 10 cases in medical group and eight cases in lateral group which had fracture due to road traffic accidents. All cases in medical group had concomitant fibula fracture while such cases were 10 in lateral group. One case in each group developed infection after surgery. There was one case of superficial skin dehiscence and one case of hardware problem in medial group compared to none in lateral group. Two cases from medial group required removal of implant compared to none from medial group.

Conclusions: Lateral distal tibial LCP seems to provide biological advantage than medial distal tibial LCP without difference in biomechanical properties of implants. Single lateral incision technique is an ingenious, biologically sound, and cosmetically superior for fixation of both lower third tibia & fibula fractures together.

A high degree of suspicion and accurate reduction is pivotal in restoring the functional outcome of the hand. In our case report, a forty year old man presented with ulnopalmar dislocation of the fifth carpometacarpal joint and was treated with open reduction and K wiring. We review the literature and discuss the available methods of management.
Toropets in the Territorial and Administrative System of the Grand Duchy of Lithuania and the Moscow State at the End of the 15th — 16th Century
Authors: Stepanova Iuliia
Published: October 2021

The article is devoted to the peculiarities of the territorial, administrative and settlement structure of Toropets and Toropets uezd at the end of the 15th — 16th centuries. During the period when Toropets was part of the Grand Duchy of Lithuania, it was influenced by its peripheral position and its status as a state settlement, direct tax collection and at the same time maintaining relative independence. Communal traditions inherited from the Old Russian period were also preserved. The involvement of both urban and rural population in crafts activities was recorded, which influenced the formation of special territories (perevaras) in the Toropets uezd. The territories of volosts and a perevaras according to the scribe book of 1540 were localized. The territories of perevaras were within the borders of volosts. The inhabitants of the volosts and the townspeople of Toropets owned the side honey trees. In the city, the yards of shabry are recorded — the collective landowners, and in the county, on the territory of the crossing — the “nest” of settlements under a generalizing name, which served as a means of identifying the object of taxation. After Toropets joined the Moscow state, these features remain. However, the community land ownership and honey craft gradually decline throughout the 16th century.
