ABSTRACT

Introduction
The aim of this study was to analyze the effects of 16 wk of Muay Thai practice on body perception, self-esteem, and quality of life in adolescents with overweight/obesity.

Methods
The sample consisted of adolescents with overweight/obesity, aged 10–17 yr. Overweight/obesity was confirmed using body mass index (BMI) and body fat (BF). Body mass and height were measured, from which BMI was calculated. BF was assessed using dual-energy x-ray absorptiometry. Body perception was measured using the Brazilian Silhouette Scale for Children, self-esteem was measured using the Rosenberg Self-Esteem Scale, and quality of life was measured using the 36-Item Short Form Health Survey. The Muay Thai intervention lasted 16 wk, with the initial 4 wk intended for adaptation and familiarization. Sessions were held three times per week on nonconsecutive days for 1.5 h. Protective equipment and devices, such as gloves, Thai pads, gauntlets, and head and rib protectors, were used. Training intensity was maintained between moderate and high according to the rate of perceived exertion scale. The control group did not perform any type of systematic training.

Results
There was a statistically significant group effect for self-esteem only (P < 0.01; effect size (η
2) = 0.13). When analyzing η
2, there was a group × time interaction in the pain domain of quality of life (P = 0.07; η
2
p = 0.11) considered medium to large. Furthermore, increases were observed in the prevalence of healthy self-esteem (before, 65.0%; after, 73.1%) and satisfaction with body image (before, 0%; after, 3.8%) in the Muay Thai group.

Conclusion
Muay Thai led to increased prevalences of individuals satisfied with their body image and with healthy self-esteem, as well as an increase in the pain domain score of quality of life in adolescents with overweight/obesity.
Comparison Between Mean-Variance and Monotone Mean-Variance Preferences Under Jump Diffusion and Stochastic Factor Model

Published: September 2024

This paper compares the optimal investment problems based on monotone mean-variance (MMV) and mean-variance (MV) preferences in a Lévy market with an untradable stochastic factor. It is an open question proposed by Trybuła and Zawisza. Using the dynamic programming and Lagrange multiplier methods, we get the Hamilton-Jacobi-Bellman-Isaacs (HJBI) and Hamilton-Jacobi-Bellman (HJB) equations corresponding to the two investment problems. The equations are transformed into a new-type parabolic equation, from which the optimal strategies under both preferences are derived. We prove that the two optimal strategies and value functions coincide if and only if an important market assumption holds. When the assumption is violated, MMV investors act differently from MV investors. Thus, we conclude that the difference between continuous-time MMV and MV portfolio selections is due to the discontinuity of the market. In addition, we derive the efficient frontier and analyze the economic impact of the jump diffusion risky asset. We also provide empirical evidence to demonstrate the validity of the assumption in real financial markets.

Published: September 2024

Emergency contraception in Poland is often referred to as the “morning-after pill”. Its legal status has changed many times. In Poland, it has only been available on prescription since 2017. Attempts have been made to change the legal status in 2024. A draft amendment to the Pharmaceutical Act was then submitted to Parliament. However, the bill was vetoed by the President of the Republic of Poland. In response to the veto, the Minister of Health issued a decree on a pilot programme in the field of pharmacists’ services related to reproductive health. In connection with this regulation, a question arose for pharmacists: whether it is necessary to obtain the consent of the legal guardian of minors who want to use the programme. Therefore, the aim of the work was a legal-comparative and dogmatic-legal analysis of legal acts in the field of reproductive health. A review of the data shows that while the pharmacist carries out the activities indicated in the pilot programme for pharmacist services about reproductive health, health services are provided to patients. Therefore, in the case of minor patients under 16 years of age, or who are over 16 but under 18 years of age, the consent of their legal representatives is required. It should also be noted that the term “pharmacist service” used in the title is not defined in any way in the law (unlike the term “pharmaceutical service”) and does not constitute a definition that would allow the statement to be made that it is another unlisted activity that exempts the pharmacist from the obligation to obtain the consent of the legal guardian. It should therefore be assumed that this consent is necessary to provide the service.

Unified atmospheric attenuation models for visible and infrared wavelengths
Authors: Elamassie Mohammed , Uysal Murat 
Published: September 2024

Optical wireless communication (OWC) encompasses the utilization of optical frequencies, including visible light (VL) and infrared (IR), for unguided data transmission. Two common terms within this field are free-space optical (FSO) communication, which involves laser-based systems for long-distance point-to-point transmission at IR wavelengths, and visible light communication (VLC), which refers to LED-based systems with shorter transmission ranges at VL wavelengths. For outdoor operation of these systems, it is critical to understand the interaction of optical signals with the propagation environment. The extinction coefficient measures how strongly a light at a specific wavelength is attenuated as a result of its passage through a medium. Over the years, many studies have attempted to determine the extinction coefficient in various atmospheric conditions; however, the majority of these studies are limited to the IR spectrum and also come with several other constraints. In this paper, we use MODTRAN (MODerate resolution atmospheric TRANsmission) software, which solves the radiative transfer equation (RTE) for the given input parameters of operation wavelength, the observer altitude, target altitude, and path length in km. First, we extract the transmittance of the optical beam through fog, rain, cloud, drizzle, and aerosol through extensive simulations in the MODTRAN for optical wavelengths of 350–1550 nm. Then, we use a non-linear curve fitting to obtain closed-form expressions for all these atmospheric conditions.

Background
Mood disorders involve a complex interplay between multifaceted internal emotional states, and complex external inputs. Dynamical systems theory suggests that this interplay between aspects of moods and environmental stimuli may hence determine key psychopathological features of mood disorders, including the stability of mood states, the response to external inputs, how controllable mood states are, and what interventions are most likely to be effective. However, a comprehensive computational approach to all these aspects has not yet been undertaken.

Methods
Here, we argue that the combination of ecological momentary assessments (EMA) with a well-established dynamical systems framework—the humble Kalman filter—enables a comprehensive account of all these aspects. We first introduce the key features of the Kalman filter and optimal control theory and their relationship to aspects of psychopathology. We then examine the psychometric and inferential properties of combining EMA data with Kalman filtering across realistic scenarios. Finally, we apply the Kalman filter to a series of EMA datasets comprising over 700 participants with and without symptoms of depression.

Results
The results show a naive Kalman filter approach performs favourably compared to the standard vector autoregressive approach frequently employed, capturing key aspects of the data better. Furthermore, it suggests that the depressed state involves alterations to interactions between moods; alterations to how moods responds to external inputs; and as a result an alteration in how controllable mood states are. We replicate these findings qualitatively across datasets and explore an extension to optimal control theory to guide therapeutic interventions.

Conclusions
Mood dynamics are richly and profoundly altered in depressed states. The humble Kalman filter is a well-established, rich framework to characterise mood dynamics. Its application to EMA data is valid; straightforward; and likely to result in substantial novel insights both into mechanisms and treatments.

ObjectiveThis study aimed to determine the prevalence of hearing loss and identify associated risk factors in a Chinese population aged 45 years and older.Study designThis study employed a cross-sectional research design. Data from the 4th wave survey of the China Health and Retirement Longitudinal Study (CHARLS) conducted in 2018 were utilized. Participants were assessed using self-reported questionnaires, and various demographic and comorbidity factors were analyzed to elucidate the risk factors associated with hearing loss.MethodsA total of 17,695 individuals from 10,257 households in 450 villages and urban settlements were included in the study. Hearing loss was assessed through self-reported questionnaires. Risk factors, including demographic characteristics and comorbidities, were analyzed to identify associations with hearing loss.ResultsThe study population had a hearing loss prevalence rate of 17.9% (n = 3,179). Regional variations were observed, with highest rates in Chongqing (28.67%), Yunnan (25.12%), and Qinghai (24.36%), and lowest rates in Zhejiang (17.71%), Tianjin (10.56%), and Shanghai (9.26%). Age ≥70 was associated with higher risk (OR = 3, p<0.05), while being female was associated with reduced risk (OR = 0.81, p<0.05). Higher education level showed lower risk (OR<1, p<0.05). Non-agricultural workers had lower risk (OR = 0.67, p<0.05). Fewer social activities were correlated with decreased risk (OR = 0.89, p = 0.024). Ethnic minorities had slightly higher risk (OR = 1.23, p<0.05).ConclusionThis study provides valuable insights into the prevalence and risk factors associated with hearing loss in the Chinese population aged 45 years and older. The findings emphasize the importance of early detection and intervention, particularly among older individuals and those residing in specific regions, for effective hearing loss management.

INTRODUCTION:
Real-time assessment of gastrointestinal (GI) symptoms in irritable bowel syndrome (IBS) using the experience sampling method (ESM) is suggested as a more appropriate approach than currently used end-of-day or end-of-week reports. This psychometric evaluation study assesses the validity and reliability of a previously developed ESM-based patient-reported outcome measure (PROM) for real-time GI symptom assessment in IBS.

METHODS:
This multicenter validation study included 230 Rome IV patients with IBS (80% female; mean age 41.2 years) in 3 European countries. Patients completed the electronic ESM-PROM (up to 10 random moments daily, with a weekly minimum completion rate of 33%) and an end-of-day symptom diary for 7 consecutive days. End-of-week questionnaires (Gastrointestinal Symptom Rating Scale for IBS, IBS Severity Scoring System, Patient Health Questionnaire-9, and Generalized Anxiety Disorder-7) were completed at the end of the 7-day period.

RESULTS:
The ESM assessment had a mean completion rate of 71%. Strong and significant correlations (0.651–0.956) with moderate-to-good consistency (intra-class correlation coefficients 0.580–0.779) were observed between ESM and end-of-day scores. However, end-of-day scores were significantly higher (Δ0.790–1.758, P < 0.001) than mean daily ESM scores. Differences with end-of-week scores were more pronounced, with weaker correlations (Pearson's r 0.393–0.802). ESM-PROM exhibited moderate-to-good internal consistency (Cronbach's α 0.585–0.887) across 5 symptom domains. First and second half-week scores demonstrated good-to-excellent consistency (intraclass correlation coefficients 0.871–0.958).

DISCUSSION:
Psychometric evaluation demonstrated strong validity and reliability of the ESM-PROM for real-time GI symptom assessment in IBS. In addition, the ESM-PROM provides a precise and reliable ascertainment of individual symptom pattern and trigger interactions, without the bias of peak reporting when compared with retrospective methods. This highlights its potential as a valuable tool for personalized healthcare in monitoring disease course and treatment response in patients with IBS.

Abstract
The last decade of the existence of the Soviet Union is considered by many as years of development, and many, who lived through that period, still remember those years very fondly. In many independent post-Soviet countries numerous problems required urgent solutions. This article describes the condition of libraries in Soviet Armenia and in independent Armenia, and informs about development trends, problems, and attempts to resolve them. The introduction of information technology in Armenian libraries has been quite complex and uneven, but it has had a unifying effect on library policy and librarians.

Abstract

Objectives
The main objective is to study gynecological and obstetrical emergencies among adolescents admitted to the emergency room in our department.

Methods
At the Farhat Hached University Hospital in Sousse’s Obstetrics and Gynecology Department, we carried out a retrospective study. Sociodemographic and clinical characteristics of adolescents who consulted over a period of 12 months were described.

Results
We recorded 78 emergencies during the study period, representing a frequency of 0.39 %. Gynecological and obstetrical emergencies in adolescents are dominated by abdominal-pelvic pain (36 %), followed by pregnancy diagnoses (16.7 %), and dysmenorrhea in 10 % of cases. Admission decisions were made in only 6.4 % of cases.

Conclusions
Advances in adolescent gynecology highlight the importance of specialized care for this population, crucial for preventive healthcare. Evaluation and management rely on recognizing clinical challenges and understanding specific issues.
Recent process of using nanoparticles in the T cell-based immunometabolic therapy
Authors: Chen Bingxin , Li Yangyang , Wang Hui 
Published: September 2024

Abstract
Immunotherapy is currently the main treatment for malignant tumors by activating immune cell. Metabolic reprogramming in tumor microenvironment can greatly affect the function of immune cell, and T cell is the main anti-tumor effector cell. Therefore, the T cell-based immunometabolic therapy can improve clinical efficacy. In T cell-based immunometabolic therapy, regular agents in conventional forms are difficult to achieve the intended efficacy due to poor tumor permeability and low cellular uptake. Nanoparticle-based strategy can serve as the optimal targeted drug delivery system due to co-encapsulation of multiple therapeutic agents and stable loading. Here, we intend to summarize examples of nanoparticles in the T cell-based immunometabolic therapy, and provide a comprehensive and helpful review by covering notable and vital applications of nanotechnology-based strategies for T cell-based immunometabolic therapy.
Simple waves for anti-van der Waals modified Chaplygin gas in 2-D magnetohydrodynamics
Authors: Gaurav  , Singh Lal Pratap 
Published: September 2024

Abstract
This paper presents essential findings on the reducible equations introduced by Courant and Friedrichs in their seminal work, Supersonic Flow and Shock Waves. In this paper, we discuss the presence of simple waves in a 2-D magnetohydrodynamic system with an anti-van der Waals-modified Chaplygin gas. Following the approach of Hu and Sheng (characteristic decomposition of the 2 × 2 quasilinear strictly hyperbolic systems). Appl. Math. Lett. 25(3), 262–267 (2012), and (simple waves and characteristic decompositions of quasilinear hyperbolic systems in two independent variables). Math. Methods Appl. Sci. 38(8), 1494–1505 (2015) for the characteristic decomposition of a strictly hyperbolic system, we establish the existence of simple waves for a non-reducible system. This extends Courant and Friedrichs’s fundamental finding, which was initially proposed for reducible system (R. Courant and K. O. Friedrichs, Supersonic Flow and Shock Waves, New York, Interscience Publishers, Inc, 1948, p. 464). These results enhance our understanding of simple wave behaviour in magnetohydrodynamic systems with modified Chaplygin gas, expanding the applicability of Courant and Friedrichs’s theoretical framework.

Published: September 2024

In brief
During zygotic genome activation, thousands of genes are activated, and those pre-mRNAs must be accurately spliced to support the production of functional proteins. This study shows that SON is necessary for proper nuclear speckle organization, pre-mRNA splicing, transcriptome establishment, and histone methylation in mouse preimplantation embryos.

Abstract
Thousands of genes are activated in late two-cell embryos, which means that numerous pre-mRNAs are generated during this time. These pre-mRNAs must be accurately spliced to ensure that the mature mRNAs are translated into functional proteins. However, little is known about the roles of pre-mRNA splicing and the cellular factors modulating pre-mRNA splicing during early embryonic development. Here, we report that downregulation of SON, a large Ser/Arg (SR)-related protein, reduced embryonic development and caused deficient blastomere cleavage. These embryonic developmental defects result from dysregulated nuclear speckle organization and pre-mRNA splicing of a set of cell cycle-related genes. Furthermore, SON downregulation disrupted the transcriptome (2128 upregulated and 1399 downregulated) in four-cell embryos. Increased H3K4me3, H3K9me3, and H3K27me3 levels were detected in four-cell embryos after SON downregulation. Taken together, these results demonstrate that accurate pre-mRNA splicing is essential for early embryonic development and that SON plays important roles in nuclear speckle organization, pre-mRNA splicing, transcriptome establishment, and histone methylation reprogramming during early embryonic development.
Analysis of stress-strain state of the metal plate based on discrete data of displacement values

Published: September 2024

An actual problem of stress-strain state (SSS) analysis of a bent metal plate under an uncertain acting load is solved.
A problem in the direct use of spatial interpolation for obtaining the surface of a metal plate, which is realized in the Surfer software product, is formed. It is noted that direct use of existing interpolation methods without considering physical-mechanical properties leads to results distortion. It was noted that spatial interpolation methods have analogy with the finite element method (FEM) in terms of surface display using meshes. This was the basis for comparing the results of surface modelling by FEM and grid-cell interpolation methods. The main difference of the interpolated surface was the absence of spline properties.
A new approach to solving the problem was the additional use of second and fourth-order polynomial spline functions, whose expressions are obtained from the initial and boundary conditions of the deformed plate. With its help, lines of smooth curvature, which acted as frame lines, were obtained and plotted on the grid-cell surface. The introduction of the frame lines on the grid-cell resulted in the combination of the initial discrete data with the displacement values calculated using the expressions of polynomial spline functions. A significant increase in the number of point data allowed the spatial interpolation method to extend the spline properties to the grid-cell interframe space as well. As a result, an adequate deformed surface of a metal plate was reproduced, giving it spline properties - smooth radii of curvature.

Published: September 2024

Se va a estudiar el comportamiento de un reactor electroquímico a escala piloto de compartimentos separados por separadores cerámicos, con una configuración de tipo filtro prensa, el cual fue aplicado para la recuperación de cromo hexavalente, procedente de la industria del metalizado de plásticos. Previamente, en una primera parte se determinó el régimen del fluido que lo caracteriza, utilizando distintos promotores de turbulencia, mediante la obtención de la distribución de tiempos de residencia (DTR). El conocimiento de la (DTR) es fundamental para seleccionar las mejores condiciones hidrodinámicas que se utilizarán posteriormente cuando el reactor se aplique a la recuperación de cromo hexavalente y otros tipos de metales pesados. Se ha obtenido un modelo matemático que rige el comportamiento hidrodinámico del reactor filtro prensa, el cual depende del coeficiente de dispersión y el caudal de operación.
