METAL PARTS OF THE BELT FITTINGS OF THE KRUTIK BURIAL GROUNDS OF THE IX - EARLY XI CENTURY (KLADOVKA I, II)
Authors: Милованова М.П.
Published: January 2023

Поселение Крутик - один из важных средневековых памятников Белозерья. К нему относятся могильники Кладовка I и II, выявленные в 2008 и 2009 гг. Одной из основных категорий находок, полученных на памятниках, являются металлические детали ременной гарнитуры. Они найдены в 230 экземплярах, всего из них гипотетически выделяется 12 наборов. На основании существующих аналогий наборы можно разделить на две традиции - южную и восточную. Южная является самой ранней и может быть связанна с салтовскими и мадъярскими древностями. Восточная традиция стилистически уводит нас в направлении Волжской Булгарии, Прикамья, Марийского Поволжья и имеет широкий круг аналогий. В целом эти предметы ременной гарнитуры датируются IX-XI вв.

The settlement of Krutik is an important medieval settlement of the Belozerye. It includes the burial grounds of Kladovka I and II, identified in 2008 and 2009. One of the main categories of finds obtained on the monuments are metal parts of the belt set. They are found in 230 copies, a total of 12 sets are allocated. Based on the existing analogies, they can be divided into two traditions - southern and eastern. The southern one is the earliest and may be associated with the Saltov and Madyar antiquities. The Eastern tradition is stylistically oriented in the direction of Volga Bulgaria, the Kama region, and the Mari Volga region and has a wide range of analogies. In general, these items of the belt set date back to the IX-XI centuries.

Published: January 2023

В статье представлены результаты раскопок могильника X-XII вв. Гнездилово, произведенных в 2020 г. Средневековые памятники в округе Гнездилова хорошо известны в литературе. Здесь в 1851 г. под руководством графа А. С. Уварова раскопано 28 курганов с кремациями и ингумациями, в 1980-1987 гг. под руководством В. А. Лапшина проходили широкомасштабные исследования одного из крупнейших в Суздальской округе поселений с культурными отложениями эпохи викингов. В современном ландшафте, практически полностью снивелированном распашкой, не сохранилось видимых следов курганного могильника, раскопанного в XIX в. Повторное обнаружение некрополя в 2019 г. позволило провести рекогносцировочные работы, в результате которых в раскопе площадью около 120 кв. м выявлено 15 ингумаций XI - начала XII в. в могильных ямах с западной ориентировкой и остатки кремаций, рассредоточенных в пахотном слое и заполнении ям. В 8 погребениях обнаружен сопровождающий инвентарь - стеклянные бусы, височные кольца, подвески, дирхем и денарий, железные ножи. Особый интерес представляет погребение 13 с помещенным в ногах боевым топором. Новые полевые исследования на памятнике демонстрируют, что Гнездилово было большим средневековым кладбищем с разнообразными погребальными обрядами - подкурганными кремациями и ингумациями, грунтовыми погребениями и кремациями, рассыпанными на поверхности или в неглубоких ямах.

The paper presents results of the excavations at the Viking Age burial site Gnezdilovo conducted in 2020. Gnezdilovo local area is known in medieval archaeology as a prominent place with the barrow burial ground first discovered in 1851 and the dwelling site with Late Viking Age cultural deposits, one of the local centers of Suzdal’ region, which had been under excavations in 1980-87. Non of the burial mounds survived in the landscape after the excavation campaign of 1851 which disclosed 28 barrows with cremations and inhumations (28) and appeared to leave poor perspectives for further research. Burial site, totally leveled by ploughing, was re-discovered in 2019. Trail excavations at the area of about 120 sq.m revealed 15 west-oriented inhumation burials in ground pits and remains of cremations dispersed in ploughed deposits and in pits. 8 inhumation burials contained grave goods - glass beads, temple rings, pendants, belt mounts, dirham coin and denarius, iron knives. Of special interest is burial 13 with a battleaxe placed at the feet of the deceased. Inhumation burials date the XI-th - the early XII-th cc. New field research at the site prove that Gnezdilovo was a large cemetery with diverse burial rituals (barrows with cremations and inhumations, cremations in shallow ground pits, inhumations in ground pits). Considerable part of the graves remains well preserved after the excavations conducted in the XIX-th c.

В 2019 г. при раскопках в Георгиевском соборе в г. Юрьеве-Польском обнаружены фрагменты штукатурки, которые предположительно можно было отнести к фрагментам стенного письма. Собор XIII в. не расписывался, и найденные фрагменты, вероятно, являются остатками более раннего собора XII в. Фрагменты были изучены с использованием методов: растровой электронной микроскопии с энергодисперсионным рентгеновским микроанализом, газовой хроматографии с масс-спектрометрией, рентгенофазового анализа на источнике синхротронного излучения КИСИ-«Курчатов». Результаты исследований показали присутствие в верхнем слое образцов таких пигментов, как красная охра, желтая охра, киноварь, зеленая земля. Также было выявлено наличие органических связующих на основе молока крупного рогатого скота. Особенности штукатурки позволили предположить, что первый собор был построен из каменных квадров.

During excavations in 2019 at the St. George Cathedral located in the Yuryev-Polsky town, fragments of colored wall plaster were discovered. These fragments were suggestively attributed to wall painting. The cathedral dated to the XIII century has not ever been painted and thus the fragments found had to belong to an earlier cathedral of the 12th century. The fragments were analyzed using the natural science techniques including scanning electron microscopy with energy dispersive X-ray microanalysis, gas chromatography with mass spectrometry and X-ray phase analysis implemented at the KISI-”Kurchatov” synchrotron radiation source. Our research revealed a number of mineral pigments in the samples upper layer such as: red ocher, yellow ocher, cinnabar, and green earth. More over the presence of organic binders based on cattle milk was discovered. The features of the wall plaster made it possible to assume that the first cathedral was built from stone squares.
Materials Science Optimization Benchmark Dataset for Multi-fidelity Hard-sphere Packing Simulations
Authors: Baird Sterling G. , Sparks Taylor D.
Published: January 2023

Benchmarks are an essential driver of progress in scientific disciplines. Ideal benchmarks mimic real-world tasks as closely as possible, where insufficient difficulty or applicability can stunt growth in the field. Benchmarks should also have sufficiently low computational overhead to promote accessibility and repeatability. The goal is then to win a “Turing test” of sorts by creating a surrogate model that is indistinguishable from the ground truth observation (at least within the dataset bounds that were explored), necessitating a large amount of data. In materials science and chemistry, industry-relevant optimization tasks are often hierarchical, noisy, multi-fidelity, multi-objective, high-dimensional, and non-linearly correlated while exhibiting mixed numerical and categorical variables subject to linear and non-linear constraints. To complicate matters, unexpected, failed simulation or experimental regions may be present in the search space. In this study, 438371 random hard-sphere packing simulations representing 279 CPU days’ worth of computational overhead were performed across nine input parameters with linear constraints and two discrete fidelities each with continuous fidelity parameters and results were logged to a free-tier shared MongoDB Atlas database. Two core tabular datasets resulted from this study: 1. a failure probability dataset containing unique input parameter sets and the estimated probabilities that the simulation will fail at each of the two steps, and 2. a regression dataset mapping input parameter sets (including repeats) to particle packing fractions and computational runtimes for each of the two steps. These two datasets can be used to create a surrogate model as close as possible to running the actual simulations by incorporating simulation failure and heteroskedastic noise. For the regression dataset, percentile ranks were computed within each of the groups of identical parameter sets to enable capturing heteroskedastic noise. This contrasts with a more traditional approach that imposes a-priori assumptions such as Gaussian noise, e.g., by providing a mean and standard deviation. A similar approach can be applied to other benchmark datasets to bridge the gap between optimization benchmarks with low computational overhead and realistically complex, real-world optimization scenarios.

Published: January 2023

We report piperazine-fused six-membered-cyclic dichalcogenides as rapid-response redox sensors for probes, prodrugs, and bifunctional conjugates that interface with cellular thiol/disulfide redox biology. By combining the thermodynamic stability of 1,2-dithianes with unprecedently rapid kinetics of self-immolation after reduction, these motifs are uniquely reliable and flexible reduction-based sensors for live cell applications. We synthesise four cis- and trans-piperazine-fused cyclic disulfides and diselenides by scalable, diastereomerically pure, six-step synthetic routes with just one chromatographic purification. Fluorogenic probes using these redox-active diamines are >100-fold faster activated than the previously known monoamines, which now allowed us to deconvolute the kinetics of the reduction and the cyclisation steps during activation. The diastereomers have remarkably different reductant specificity. In particular, the cis-fused disulfides are only activated by strong vicinal dithiol reductants, while trans-fused disulfides are activated even by monothiols like GSH. Thus, although both disulfides are good substrates for glutaredoxins and thioredoxins in cell-free assays, upon cellular applications the cis-disulfide probes substantially report on oxidoreductase activity in the thioredoxin system (the trans-disulfides remain promiscuously reactive). Finally, we showcase efficient late-stage synthetic diversification of the piperazine-disulfides, promising their broad applicability as cleavable bifunctional cores for redox probes and prodrugs, for solid phase synthesis, and as linkers for antibody-drug conjugates.
Selection of equipment for oil tank repair in northern conditions
Authors: Kuznetsova V. N. , Kuznetsov I. S.
Published: January 2023

Introduction. The oil industry is a key component of the economy of the Russian Federation. A large number of tanks are used to store oil, each of which needs timely repair. According to the results of some research, almost half of the accidents are caused by excess uneven settlement of the tank, which causes premature failure. To restore the serviceable and operable condition of the tanks, it is necessary to carry out repair work, the quality and efficiency of which depends on the repair equipment used. An urgent task is to justify the choice of equipment for the repair of tanks, in particular, steel tanks of a vertical type.

Methods and materials. A review of the different types of tanks was carried out and showed that vertical steel tanks are the most widely used. One of the ways to eliminate the uneven settlement of the tank is to raise it with the help of jacks and form a new base with the elimination of the slope.

Results. The repair process for a 10,000 m3 steel vertical tank was considered. The values of the mass of the tank were obtained when filling with liquid petroleum products at 1% of the maximum occupancy. The value of the load on one lifting device is obtained. The design of the device structure and the strength calculation in the Compass 3D program were completed.

Сonclusions. The most efficient type of the lift from the existing ones was determined, and its design was modernized. The strength calculation showed that the hydraulic lift is efficient under the given conditions.
Theoretical research and maintenance of electro hydraulically controlled injectors
Authors: Zhigadlo A. P. , Makushev Yu. P.
Published: January 2023

Introduction.Nowadays the part of the diesel engines for KamAZ-740 cars are operated with fuel equipment, in which the injectors have hydro mechanical control. Their main disadvantage is the low fuel pressure in front of the injector openings (less than 60 MPa) and the lack of fuel supply control.

The use of injectors with electro hydraulic control (EHC) increases the pressure in the injector cavity up to 250 MPa and control the fuel injection process. The disadvantage of the injectors with EHC is a structural complexity of a control valve, the difficulty of its regulation and coding. The object of the study is the injectors of KamAZ-740 diesel engine with electro hydraulic control of the atomizer needle stroke.

The purpose of this work is to carry out theoretical research and improve the methods of maintenance of injectors with electro hydraulic control (control valve regulation and coding), which will increase their reliability, durability and ensure a reduction in diesel fuel consumption.

Research methods.The study of the nozzle control valve is theoretical and calculated. The paper proposes a calculation method and performs theoretical studies for the influence of pressure (50 – 250 MPa) on the value of the effective flow section and the diameter of the nozzle holes of the sprayer.

For the injectors with EHC, the control valve regulation procedure has been clarified, which consists in the fact that at the beginning of regulation, the main force acting on the ball from the side of the maximum pressure in the control chamber (for example, 200 MPa) equal to 76 N is calculated (see Figure 4). Then the required spring force of 100 N is determined (20-40% more, see Figure 5). Next, the strength of the electromagnet is estimated at 140 N (20 – 40% more of the spring force, see Figure 6).

The results of theoretical research.The results of computational (theoretical) studies for the effective flow section of the sprayer and the diameter of the nozzle holes, depending on the pressure P in front of the nozzle holes, are presented.

The paper defines.1. The forces acting on the ball (57 – 105 N) depending on the pressure in the control chamber (150 – 275 MPa). 2. Spring forces (40 – 140 N) with a stiffness of 40 N /mm, depending on its compression up to 3.5 mm. 3. The forces of the electromagnet (140 – 20 N) depending on the gap between the anchor and the core (0.2 – 0.5 mm).

The method of restoring the required (rated) cyclic fuel supply when it changes as a result of replacing the control valve or adjusting is considered. The calculated values of fuel supply per cycle (mm3/cycle) from the activation time are given.

Conclusion.The results of the study are intended for organizations and enterprises engaged in diagnostics, restoration, adjustment and coding of injectors with electro hydraulic control for the needle stroke of sprayers. The results of computational studies can be used to refine the methodology of maintenance of fuel systems with electronic control (Common Rail).
Digital transport traseology based on Agisoft Metashape and unmanned aerial vehicle
Authors: Nedobitkov A. I.
Published: January 2023

Introduction. A vehicle and trace evidence analysis is one of the most requested types of examinations performed within the framework of criminal cases on road traffic accidents. The main methodical guidelines for traffic and trace evidence analyses were developed in the past century, while nowadays the fourth industrial revolution is on the rise. The industrial revolution is based on computer and information technologies, various software and hardware tools. Hence there is a vital necessity in update of the vehicle and trace evidence analysis methodology in order to conform to current-day realities.

Materials and methods. Results of use of the unmanned aerial vehicle and Agisoft Metashape software are presented in the article in the context of specific road traffic accidents. It was made clear that application of this method has the following advantages: firstly, time of fixation of objects of the roadway network, vehicles and their traces on traffic ways is significantly reduced; secondly, fixation accuracy is improved; thirdly, use of the method makes it possible to establish all actual facts needed to perform analysis of the mechanism of a road traffic accident. Digital models obtained using this method could be used for 3D modeling, what offers an opportunity for more accurate determination of a mode and an angle of approach of vehicles before an accident with significant reduction of financial and time expenditures.

Results. It was shown that digital models of road traffic accident sites and vehicles could be entered into the case file in general as well as into an expert’s statement in particular. Such entering will improve objectivity and believability of the conducted examination. Digital models of road traffic accident sites (digital twins) could be stored for an indefinitely long time and could contain the entire information on physical accident scene. Therefore such digital models are considered as valuable information while performing additional or repeated examinations.

Conclusion. The proposed method for creating a digital model of a vehicle or a site of a traffic accident can be used in digital transport traceology.

Authors: Rodionov O. A. , Rasheed B.
Published: January 2023

Introduction: The field of unmanned technologies is rapidly developing and a lot of research is being conducted on the practical application of artificial intelligence algorithms to solve complex problems on the road. The difficulties in the perception of the surrounding world by the machine led to the appearance of special High definition maps. These maps are used to simplify and improve the quality and reliability of other subsystems from the stack of autonomous technologies, such as localization, prediction, navigation and planning modules. In modern literature, there are mainly works on the practical application of such maps, and the process of developing a map remains outside the scope of consideration.

The aim of the work is to create a methodology for designing semantic maps for autonomous vehicles with a detailed description of each of the development stages.

Materials and methods: The article describes the methodology for creation of HD maps, which includes the stages of data collection using SLAM (Simultaneous localization and mapping) approach, its further processing and the development of the semantics of the road network. The described algorithm is applied in practice to develop the semantic map of Innopolis city area using SLAM approach with LIDAR inertial odometry via smoothing and mapping (LIO-SAM).

Results: The main stages of the methodology for creating HD maps for autonomous vehicles have been proposed and investigated. Authors implemented the proposed concept in practice and described in detail the process of creating a semantic map for the Innopolis city area.

Conclusions: The proposed methodology can be used for any type of autonomous robots (ground vehicles, unmanned aerial vehicle, water transport) and can be implemented in different road conditions (city, off-road), depending on the information the map should provide for the implementation of the goals and objectives set for the autonomous vehicle.
Updating parameters of an information model for road construction flow in work development project
Authors: Bobrova T. V.
Published: January 2023

Introduction. The article reflects the main trends and problems in the development of information modelling technology in the Russian road industry. A set of mutually integrated domestic software products is presented that provide the formation and support of information models of roads in the life cycle process. It has been established that the transition from traditional simulation modelling of building flows to information modelling of flow systems requires a detailed analysis of the lower elements of the flow structure. Such elements in the system of an integrated road construction flow include linear specialized detachments.

Models and methods. A single information model of an object as part of the construction organization project (COP) forms the overall strategy for managing the construction of the road. At the stage of the project for the production of works (PPW), it is necessary to take into account the technical and technological features of the contractor in the calendar plan. At the PPW level, it is necessary to create a new structure and define the parameters of this structure in such a way as to satisfy the specified restrictions established by the COP in terms of time and costs,  and also provide for certain reserves for insuring possible risks.  The aim of the study is to develop a methodology for information modelling of a specialized road flow as part of the PPW, taking into account the optimization and updating of its parameters in relation to the conditions of the contracting organization.

Results. A modelling algorithm has been developed for creating an updated structure of a specialized linear flow in an integrated computer environment, which provides visualization of a construction site, control and operational management of work in a shared data environment. An example of the implementation of this method is considered when designing a specialized flow, first as part of a COP, with the subsequent updating of this model in the MS Project program when developing a PPW based on a typical flow chart.

Conclusion. The use of information modelling creates wide opportunities for analyzing and monitoring the progress of work at the construction site of a linear flow, and also allows you to perform prompt automated restructuring of the loading of detachment vehicles when adjusting the amount of work at the work sites.

Tutela provisória: uma abordagem à luz do novo Código de Processo Civil.
Authors:   , Filippo Guilherme Lucas
Published: January 2023

O instituto da tutela provisória, disciplinado pelo Livro V e entre os artigos 294 e 311 do novo Código de Processo Civil, sofreu inovações importantes com relação às disposições estabelecidas pelo Código de Processo Civil de 1973, agora revogado. As alterações trazidas pela nova legislação deram uma roupagem diferenciada ao instituto da tutela provisória e, pelo que parece, contribuíram principalmente para o desenvolvimento de sua efetividade. O novo Código de Processo Civil realizou a divisão da tutela provisória em duas categorias: tutela de urgência e tutela da evidência. Provocando a unificação entre as tutelas de urgência satisfativas e conservativas (tutela antecipada e tutela cautelar), o novo Código promoveu a aproximação entre o direito processual civil brasileiro e o europeu. Todavia, parte da doutrina enfrenta com relutância algumas das disposições inauguradas pelo novo Código, o que faz surgir discussões sobre a constitucionalidade e a forma de emprego de algumas medidas. Em virtude do frescor do assunto pela recente publicação do novo Código de Processo Civil, que entrará em vigor no dia 18 de março de 2016, o estudo da matéria será pautado em posicionamentos contemporâneos, valendo-se principalmente do método bibliográfico de pesquisa pela existência de uma infinidade de obras que abordam o tema de maneira aprofundada.
Reflections on mathematics ability, anxiety, and interventions
Authors: Brewster Barbara Jane , Miller Tess
Published: January 2023

Competency in mathematics is needed to respond to the vast employment opportunities available in the STEM sectors. These employment opportunities all require basic foundational mathematics skills, yet there is a shortfall of mathematics abilities due, in-part, to mathematics anxiety. Mathematics anxiety can surface as fear and avoidance of mathematics and has been linked to low mathematics performance and ability (Ashcraft, 2002; Luttenberger et al., 2018). This thought paper (Snell, n.d.), paper begins with a synthesis of research on mathematics anxiety including the known causal factors: cognitive/affective, social, and genetic as well as the recently proposed causal factor, missed opportunity (Brewster & Miller, 2020). Missed opportunity refers to cases where an individual who is capable academically to comprehend mathematics but has missed the opportunity to learn basic foundational skills in mathematics. Missing the opportunity to learn foundational concepts in mathematics places great stress, which can result in feelings of anxiety. Next, a synthesis of interventions for mathematics anxiety such as mindfulness exercises (Brunyé et al., 2013) and expressive writing (Brewster & Miller, 2022; Park et al., 2014) are discussed, which led to the realization that interventions are more complex than previously reported given that other factors can affect interventions such as duration of writing, quality of instruction, or additional stressors causing anxiety, including test anxiety. Knowing the causal factors influencing an individual’s mathematics anxiety may prove beneficial to designing more focused and influential interventions.
Effect of Partial Replacement of Coarse Aggregate with Electronic Waste Plastic in Light Weight Concrete
Authors: Botchway Derrick Nii-Laryea , Bentil John , Henaku Charles Yeboah
Published: January 2023

This study assessed the usefulness of the replacement of coarse aggregate partially with electronic waste (e-waste) plastic in lightweight concrete since developing countries have been challenged with management of e-waste as well as high cost of coarse aggregates for concrete production. Coarse aggregates were replaced with e-waste plastic in concrete at 5%, 10%, 15%, and 20% for a concrete class of C20. The particle size distribution of the e-waste plastic aggregates was determined as well as the slump, compressive strength, water absorption and bulk density of the concrete. Generally, the slump decreased as the e-waste increased. The compressive strengths decreased for the 5% and 10% replacement of coarse aggregates with e-waste but increased for the 15% and 20% replacement of coarse aggregate with e-waste. 0% water absorption was obtained for the 15% and 20% e-waste content while the 10% e-waste concrete obtained 0.01% and the 5% e-waste obtaining of 0.013% after 28days of curing. The densities of 5%, 10%, 15% and 20% e-waste plastic content decreased as compared to the 0% e-waste plastic content. The values of compressive strength obtained showed that coarse aggregate replacements by e-waste plastic at 15% and 20% may be appropriate for lightweight concrete of class C20/25 since compressive strengths ranged between 16.09 Nmm–2 and 22.87 Nmm–2. This implies that partial replacement of coarse aggregate with e-waste plastic may be useful for lightweight concrete as well as helping in eradicating the environment of the menace of e-waste plastic.

Various natural antibacterial materials from plant extract can be used as an attempt to inhibit the growth of Streptococcus mutans and it has minimal side effects, one of which is butterfly pea extract. From the research that has been done, butterfly pea extract contains phytochemical compounds such as alkaloid, flavonoid, tannin, saponin, and ternatin which act as antibacterial agents against the growth of microorganisms. Objective: To prove that butterfly pea extract has potential as an antibacterial agent that can be observed from the formation of the inhibition zone of Streptococcus mutans. Methods: The in vitro study was conducted by diffusion method using 12 test groups with 4 times repetitions. The test group consisted of a positive control group with chlorhexidine 0.2%, a treatment group with 10%, 20%, 30%, 40%, 50%, 60%, 70%, 80%, 90%, and 100% concentration of butterfly pea extract, and a negative control group with sterile distilled water. The samples were then incubated at 37ºC under anaerobic conditions for 24 hours. The inhibition zone formed was then measured using a caliper in millimeters (mm). Results: Butterfly pea extract can inhibit the growth of Streptococcus mutans starting at a concentration of 50%. One Way ANOVA test results P=0.001 (P<0.05), means that there are differences in the inhibition zone of Streptococcus mutans in each group. Conclusion: Butterfly pea extract can inhibit the growth of Streptococcus mutans.
Epistemología en la formación del profesorado de ciencias: Herramientas conceptuales del positivismo lógico y del Círculo de Viena
Authors: Clemente Gonçalves Marco Aurelio , Adúriz-Bravo Agustín
Published: January 2023

El presente trabajo busca indagar en el movimiento denominado Círculo de Viena, especialmente en lo que se refiere a sus tesis fundamentales de carácter positivista lógico, con el fin de identificar contribuciones conceptuales al debate filosófico y epistemológico dentro de la formación del profesorado de ciencias naturales. Hace parte de un estudio más amplio sobre el estado actual de los fundamentos epistemológicos propuestos para la formación docente en dos programas académicos de una Universidad pública del nordeste brasileño. La metodología elegida es la de investigación bibliográfica: se analizan fuentes primarias y secundarias vinculadas al positivismo lógico y se busca reconocer posibles trazas de sus ideas en la formulación del currículo de formación de profesores en la mencionada institución. Los resultados muestran que, a pesar de la notable influencia que el positivismo lógico tuvo en el moldeado de la epistemología (o filosofía de la ciencia) anglosajona del siglo XX, en el ámbito de las carreras de formación docente en el interior del estado de Bahía existen solo débiles referencias al modo analítico de entender la ciencia propugnado por esta escuela.

Published: January 2023

Background: Endometrial ablation is a safe and effective minimally invasive surgical procedure. Despite the high success rate of endometrial ablation for heavy uterine bleeding management, some patients experience persistent symptoms after the procedure, necessitating a hysterectomy. The aim of this study is to determine the pre-operative clinical predictive factors of failure of endometrial ablation in the management of uterine bleeding. Methods: Retrospective cohort study of endometrial ablation procedures performed for treating heavy uterine bleeding. Results: Ninety five patients were included in the study. The failure rate was 24.2%. There was a statistically significant association between ablation failure and fluid deficit (p = 0.002) and intra-operative blood loss (p = 0.047). There was a statistically significant moderate association between adenomyosis (p = 0.003, φ = 0.37) and failed endometrial ablation. However, the age, body mass index (BMI), parity, number of miscarriages, number of cesarean sections, uterine length, endometrial thickness and procedure duration had no significant association with endometrial ablation. There was no significant relationship between the uterine abnormalities in general and the outcome of the endometrial ablation (p = 0.637). However, patients with combined adenomyosis and dysmenorrhea had a statistically significant association with outcome of the endometrial ablation (p = 0.016, φ = 0.28) and were more likely to have a failed endometrial ablation (crude odds ratio (COR) = 4.67, 95% confidence interval (CI), 1.35–16.09). Logistic regression to adjust for related factors revealed that the adenomyosis (adjusted odds ratio (AOR) = 50.83, 95% CI, 3.64–706.75, p = 0.003) and fluid deficit (AOR = 1.003, 95% CI, 1.000–1.006, p = 0.044) had a higher likelihood of an unsuccessful outcome. Hysterectomy was performed in 47.8% of patients who had failure of the ablation. Conclusions: Among pre-operative factors, adenomyosis, fluid deficit and combined adenomyosis and dysmenorrhea were found to predict failure of hysteroscopic endometrial ablation. Clinical Trial Registration: It was registered in https://www.clinicaltrials.gov database with Identifier: NCT05483348.
The Rate of Gestational Weight Gain are Associated with Preterm Birth in Pregnant Women at Low Risk for Preterm Birth: A Single-Center, Observational Study

Published: January 2023

Background: Preterm birth (PTB) is the main cause of infant disease and death worldwide. Approximately 70% of neonatal deaths and 36% of infant deaths worldwide are caused by premature birth. Gestational weight gain (GWG) is associated with adverse pregnancy outcomes. This study explored the relationship between the rate of GWG and PTB among pregnant women at low risk of preterm birth. Methods: Our study used a cohort of mother-child pairs with a one-and-a-half-year follow-up from January 2020 to June 2021. We excluded pregnant women with undisputed high-risk factors for PTB and the remaining women were considered the low-risk group. The average rate of GWG was utilized in this research as the measure of GWG. Multivariate logistic regression was used to evaluate the relationship between GWG and PTB among pregnant women at low risk for preterm birth. Results: The final cohort study of mother-child pairs included 3480 pregnant women in the low-risk group. Women with low GWG had a higher possibility of PTB than those with adequate GWG. Comparing underweight women with an adequate GWG rate to underweight women with a low GWG rate, PTB risk increased by 2.52-fold with a low GWG rate. Compared to women with adequate GWG, underweight women with excessive GWG had significantly higher odds of PTB. No significant results were observed for pregnant women classified as overweight or obese. Conclusions: A reasonable GWG during pregnancy can effectively reduce the risk of PTB, especially for pregnant women with low pre-pregnancy body mass index. Low or excessive GWG may lead to an increased risk of PTB.

Published: January 2023

Background: The objective was to compare the use of micronized vaginal progesterone 800 mg daily and oral dydrogesterone 40 mg daily in the endometrial preparation for frozen-thawed embryo transfer (FET). Methods: Prospective randomized study with women undergoing FET along with hormone replacement therapy for endometrial preparation, between September 2019 and February 2021. A total of 73 patients were randomly selected and orally received 40 mg/day dydrogesterone (DYD group, n = 36) or 800 mg/day micronized vaginal progesterone (MVP group, n = 37) after endometrial preparation with transdermal estradiol. The main outcome was a viable ongoing pregnancy with 12 weeks of gestation. Biochemical pregnancy, clinical pregnancy and live birth rates were the secondary outcome. Results: The reproductive outcomes in FET cycles were similar, with pregnancy and Live birth rates in the didrogesterone and MVP treatment groups being respectively: Biochemistry (38.9%/37.8%; p = 0.189 [95% confidence interval (CI) = –23.4–21.2]), Clinical (33.3%/35.1%; p = 0.192 [95% CI = –20.0–23.6]); 12 Weeks Pregnancy (33.3%/32.4%; p = 0.196 [95% CI = –22.4–20.6]); Live birth (33.3%/32.4%; p = 0.196 [95% CI = –22.4–20.6]). Conclusions: 40 mg/day dydrogesterone and 800 mg/day MVP revealed similar reproductive results in FET cycles. The use of oral dydrogesterone is a reasonable option, may be more accepted by patients in terms of ease of use and lower cost. Clinical Trial Registration: U1111-1247-1845.
