BACKGROUND: Abnormal labor is the most common complication of labor. It occurs in 10-15% cases of labor and is an indication for operative delivery in a third of all cases. Until now, there are no effective ways to predict abnormal labor. Meanwhile, the use of high-tech forecasting methods is not available for a wide range of obstetric institutions in the Russian Federation. AIM: The aim of this study was to create a technology for predicting abnormal labor, based on generally available methods of laboratory and instrumental research. MATERIALS AND METHODS: Based on the data collected in the Regional Clinical Hospital Perinatal Center, Chita, Russia in 2018-2021, the retrospective analysis of 200 cases of labor was carried out. The total sample was divided into four study groups: 100 women with normal labor activity (group 1), 30 women with uterine inertia (group 2), 30 women with incoordinate uterine activity (group 3), and 50 women with excessive uterine activity (group 4). The groups were comparable in terms of age, anthropometric parameters and extragenital pathology. All women on the eve of labor (1-2 days) underwent general clinical and ultrasound examination. Statistical processing of the results was carried out using the IBM SPSS Statistics version 25.0 software. RESULTS: The technology for predicting abnormal labor is implemented based on a multilayer perceptron, with the percentage of incorrect predictions being 21.3%. The structure of the trained neural network included nine input neurons: labor parity, gestational age, leukocyte count, erythrocyte sedimentation rate, total protein concentration, amniotic fluid index, biparietal size, as well as fetal head and abdomen circumference. CONCLUSIONS: An integrated approach based on generally available laboratory and instrumental research methods, such as complete blood count and biochemical blood test, as well as ultrasound examination, on the eve of labor allows for predicting the abnormal labor development with an accuracy of up to 70%. The use of this technology in clinical practice will help, in the future, not only to prevent abnormal labor, but also to reduce the incidence of adverse obstetric and perinatal outcomes.

The Difference

Purpose Augmentative and alternative communication (AAC) is an intervention approach that can promote communication and language in children with multiple disabilities who are beginning communicators. While a wide range of AAC technologies are available, little is known about the comparative effects of specific technology options. Given that engagement can be low for beginning communicators with multiple disabilities, the current study provides initial information about the comparative effects of 2 AAC technology options—high-tech visual scene displays (VSDs) and low-tech isolated picture symbols—on engagement. Method Three elementary-age beginning communicators with multiple disabilities participated. The study used a single-subject, alternating treatment design with each technology serving as a condition. Participants interacted with their school speech-language pathologists using each of the 2 technologies across 5 sessions in a block randomized order. Results According to visual analysis and nonoverlap of all pairs calculations, all 3 participants demonstrated more engagement with the high-tech VSDs than the low-tech isolated picture symbols as measured by their seconds of gaze toward each technology option. Despite the difference in engagement observed, there was no clear difference across the 2 conditions in engagement toward the communication partner or use of the AAC. Conclusions Clinicians can consider measuring engagement when evaluating AAC technology options for children with multiple disabilities and should consider evaluating high-tech VSDs as 1 technology option for them. Future research must explore the extent to which differences in engagement to particular AAC technologies result in differences in communication and language learning over time as might be expected.

An overview of the data on features of ultrasound examination of the gallbladder with various forms of pathology in children is presented. We examined 650 conditionally healthy children and 840 children with diseases of the abdominal cavity organs, cardiovascular system, and some infectious diseases. The diffuse thickening of the gallbladder wall was established to be the possible result of a wide range of pathological conditions, both of surgical and non-surgical origin. It is shown that sometimes it is necessary to conduct frequent dynamic studies, especially in cases where the primary disease of the gallbladder cannot be ruled out. As a rule, the recognition of the cause of the response of the gallbladder wall and its exclusion as a result of appropriate treatment leads to a normalization of the morphology and function of the gallbladder.

Introduction: High fetal head station has been associated with prolonged labor and delivery outcomes. Although clinical assessment of fetal head station is both subjective and unreliable, women with prolonged labor are subjected to multiple digital vaginal examinations. The use of ultrasound has been proposed to aid in the management of labor since 1990s. Ultrasound examination is more accurate and reproducible than clinical examination in the diagnosis of fetal head station and in the prediction of arrest of labor. Ultrasound examination can, to some extent, distinguish those women destined for spontaneous vaginal delivery and those destined for operative delivery and  may predict the outcome of instrumental vaginal delivery. Such a technique has the potential to reduce the frequency of intrusive internal examinations and associated infection and could be useful in allowing the assessment of women in whom digital VE is traumatic or contra-indicated. Intrapartum ultrasound not only provides objective and quantitative data in labor, but also helps to make more reliable clinical decisions aiming to improve obstetric outcomes of both the mother and fetus as a supplementary tool for active management. Aim of the work: This study aims at assessing the value of intrapartum transperineal ultrasonography as a quantitative and objective tool in the evaluation of progress of labor and prediction of mode of delivery. Subjects: This study was a prospective observational study conducted on 600 primiparous women in active first stage of labor admitted to Kasr Al Ainy maternity hospital from January 2017 to June 2018. The studied population was divided into two groups. Group A of 300 women with normal progress of labor and group B of 300 women with prolonged 1st stage of labor. Methods: Fetal head station(FHS) was assessed clinically by digital vaginal examination (dVE) and sonographically by transperineal ultrasound measurement of  head perineal distance (HPD) and angle of progression (AOP). Intrapartum care of the patient continued as normal based only on digital vaginal examinations using the modified WHO partogram. (1). Statistical analysis was targeted towards assessing the potential of the intrapartum ultrasonography in the evaluation of progress of labor and prediction of mode of delivery. Results: All studied parameters for assessment of FHS (dVE, HPD, and AOP) significantly corelated with each other and with both progress of labor and mode of delivery with P value (<0.001). The highest sensitivity for prediction of progress of labor is observed using dVE (83%), the highest specificity is observed using AOP (78.3%). The highest sensitivity for prediction mode of delivery is for combined HPD & AOP (97.7%) while the highest specificity is for AOP (81%). When combining both HPD and AOP for prediction of mode of delivery, the assessment of both parameters was found to have a high sensitivity of 97.7% and a high positive predictive value of 86.63%. Conclusion: Intrapartum ultrasound examination is a valuable tool in the prediction of progress of labor and mode of delivery. The assessment of fetal head station by transperineal ultrasound measurement of HPD and AOP is much more informative of the progress of labor and the mode of delivery than digital assessment of fetal head station.

Abstract BACKGROUND Hypothalamic obesity caused by childhood–onset craniopharyngioma results in long–term cardiovascular morbidity. Knowledge about clinical markers and risk factors is rare. PATIENTS AND METHODS A cross–sectional study on transthoracic echocardiographic parameters was performed to determine the associations with clinical and anthropometric parameters in 36 patients with childhood-onset adamantinomatous craniopharyngioma. RESULTS Body mass index (BMI) correlated with the thickness of interventricular septum in diastole (IVSd) (r=0.604, p&lt;0.001) and left ventricular diastolic posterior wall in diastole (LVPWd) (r=0.460, p=0.011). Due to wide range of disease duration, 17 pediatric and 19 adult patients were analyzed separately. In the adult subgroup (age at study ≥18 years), BMI correlated with IVSd (r=0.707, p=0.003), LVPWd (r=0.592, p=0.020) and left ventricular internal diameter in diastole (LVIDd) (r=0.571, p=0.026). In the pediatric subgroup (age at study &lt;18 years), no correlation between cardiac parameters and BMI was observed. Only LVIDd correlated with disease duration (r=0.645, p&lt;0.001). All cardiac functions were within the normal range, indicating no association with severe functional impairments. CONCLUSIONS Cardiac remodeling in patients with childhood-onset craniopharyngioma correlates with the degree of hypothalamic obesity and disease duration. However, echocardiography has limited sensitivity in craniopharyngioma patients with obesity, so cardiac magnetic resonance imaging (MRI) should be considered as an alternative diagnostic approach for patients with craniopharyngioma and hypothalamic obesity.

Modern drilling rigs are complexes of high-tech equipment operated in difficult climatic and technological conditions, characterized by sudden spasmodic changes in the process of drilling a well, which contributes to increased wear of drilling components and increases the likelihood of pre-emergency and emergency situations. Drilling equipment has a wide range of characteristics and technological parameters, the values of which are available during drilling due to the use of modern software and hardware systems for processing geological and technological information. In order to single out the most frequent pre-emergency situations in practice and to preliminarily determine the set of signs necessary for their recognition, a corresponding analysis of the complications arising during well drilling has been carried out.

This article contributes to ‘sociology of professions’ theory through the study of changes that occurred in US airline pilots’ work. Findings reveal that airline pilots are quasi-professional experts who developed specialized skills based on talent and experience which allowed them to work autonomously and enjoy a correspondingly high sense of trust and prestige for which they were often well compensated. However, results of this study suggest high labour costs and weak professional communities leave quasi-professional experts vulnerable to managerial cost-cutting and work intensification agendas, particularly during periods of merger, downsizing and other forms of industry restructuring. Findings signal a deprofessionalization of some elite fields in which experts’ specialized skills become devalued and the industry-specific nature of their expertise reduces career options and job mobility. Although the present study identifies this trend in aviation, recent changes in a wide range of industries from healthcare to high-tech portend applicability in a variety of domains.

The current Strategy of Innovative Development of the Russian Federation for the period up to 2020 and the Strategy of Scientific and Technological Development of the Russian Federation determine the goals, priorities and objectives of the state innovation policy and scientific and technological development of the country. A significant role is given to areas that allow us to obtain scientific and technical results that are the basis for increasing the innovative level of production and consolidating the country's position in the foreign market. Among the priority areas is the aviation industry, namely the sector of aircraft engine construction. The creation of aircraft engines is currently one of the most science-intensive and high-tech tasks of the domestic aircraft industry. However, the analysis of the current state of implementation of programms in this area shows that the problems of their functioning and development are not always solved taking into account a wide range of emerging risks, the negative impact of which can lead to significant financial losses. To develop effective methods for assessing and minimizing risks, it is necessary to first analyze and classify them. In the article, based on the analysis, a system of classification of risks arising during development aircraft engines. The results obtained will allow us to give a preliminary qualitative assessment of the negative events that occur at various stages of the development of aircraft engines.

Advanced Manufacturing (AM) markets are a major factor of contemporary worldwide growth that to a large extent determines countries’ competitiveness. Strengthening and/or optimizing the positions on AM markets is among the major challenges for modern industrial policy. This article discusses the structure and dynamics of the development of advanced manufacturing markets, as well as the specifics of the policies of the countries strengthening their positions in these markets. Gaining entry into AM markets currently implies individual countries’ and industries’ adopting different models which combine a wide range of factors. Small nations are rapidly applying such approaches, gaining advantages and thus increasing their competitive edge, which creates certain challenges for leading high-tech countries too slow to adjust their industrial policies. So far the basis for Industry 4.0 markets is just emerging, and remains limited to a few nations including developing ones. Country cases are presented below to illustrate the development of AM markets. The authors conclude that in the current context, no universal approaches to shaping a successful industrial policy remain. The most productive strategy is to combine the unique advantages of a particular economy.
