Published: August 2023

The most common cause of antibiotic resistance is the irrational use of antibiotics. Most of the irrational use of antibiotics is related to use in the community and the prevalence of self-medication in different populations. This review aimed to explore the prevalence of self-medication with antibiotics in European countries and the main sources of antibiotics. An online search of Pubmed and Scopus was conducted to identify relevant studies. A two-phase mapping approach was used. All steps in this scoping review were carried out using the Covidence® software. A total of 22 studies were included. The prevalence of self-medication with antibiotics is greater in Southern European countries than in Northern and Western European countries. The main sources of over-the-counter antibiotics are community pharmacies and leftovers from previous courses. Targeted communication strategies and interventions are needed to reduce the overuse of antibiotics and to slow down the spread of antibiotic resistance until new classes of effective antibiotics are developed.

Published: August 2023

Background

Tracheal intubation in critically ill patients remains high-risk despite advances in equipment, technique, and clinical guidelines. Many patients with COVID-19 were in respiratory distress and required intubation that is considered an aerosol-generating procedure (AGP). The transition to videolaryngoscopy as a routine first line option throughout anesthetic and ICU practice has been reported. We evaluated the ease of intubation, success rate, use of accessory maneuvers and adverse outcomes during and 24 hours after intubation with the McGrath videolaryngoscope.

Methods

This was a prospective, observational single center study conducted at non-operating room locations that included all adults (>18 years old) with suspected or confirmed COVID-19 infection and were intubated by McGrath videolaryngoscope. The anesthesiologist performed tracheal intubation were requested to fill online data collection form. A co-investigator was responsible to coordinate daily with assigned consultants for COVID intubation and follow up of patients at 24 hours after intubation.

Results

A total of 105 patients were included in our study. Patients were predominantly male (n=78; 74.3%), their COVID status was either confirmed (n=97, 92.4%) or suspected (n=8, 7.6%). Most were intubated in the COVID ward (n=59, 56.2%) or COVID ICU (n=23, 21.9%). The overall success rate of intubation with McGrath in the first attempt was 82.9%. The glottic view was either full (n=85, 80.95%), partial (n=16, 15.24%) or none (n=4, 3.81%). During intubation, hypoxemia occurred in 18.1% and hypotension in 16.2% patients. Within 24 hours of intubation, pneumothorax occurred in 1.9%, cardiac arrest and return of spontaneous circulation in 6.7% and mortality in 13.3% of patients.

Conclusion

These results illustrate the ease and utility of the McGrath videolaryngoscope for tracheal intubation in COVID-19 patients. Its disposable blade is of significant value in protectin during tracheal intubation.

Background

Data on risk factors associated with mechanical ventilation (MV) weaning failure among SARS-CoV2 ARDS patients is limited. We aimed to determine clinical characteristics associated with weaning outcome in SARS-CoV2 ARDS patients under MV.

Objectives

To determine potential risk factors for weaning outcome in patients with SARS-CoV2 ARDS.

Methods

A retrospective observational study was conducted in the ICUs of four Greek hospitals via review of the electronic medical record for the period 2020–2021. All consecutive adult patients were screened and were included if they fulfilled the following criteria: a) age equal or above 18 years, b) need for MV for more than 48 hours and c) diagnosis of ARDS due to SARS-CoV2 pneumonia or primary or secondary ARDS of other aetiologies. Patient demographic and clinical characteristics were recorded for the first 28 days following ICU admission. The primary outcome was weaning success defined as spontaneous ventilation for more than 48 hours.

Results

A hundred and fifty eight patients were included; 96 SARS-CoV2 ARDS patients. SOFA score, Chronic Obstructive Pulmonary Disease (COPD) and shock were independently associated with the weaning outcome OR(95% CI), 0.86 (0.73–0.99), 0.27 (0.08–0.89) and 0.30 (0.14–0.61), respectively]. When we analysed data from SARS-CoV2 ARDS patients separately, COPD [0.18 (0.03–0.96)] and shock [0.33(0.12 – 0.86)] were independently associated with the weaning outcome.

Conclusions

The presence of COPD and shock are potential risk factors for adverse weaning outcome in SARS-CoV2 ARDS patients.
Influence of boulder array on the near-bed turbulent flow characteristics in a gravel bed stream - An experimental investigation
Authors: Datta Akash , Das Ratul , Majumder Mrinmoy
Published: August 2023

The present study aims to focus the turbulent flow characteristics over arrays of submerged boulders in a gravel bed stream. Round shaped boulders of diameter, Dc
= 6 cm were staggered over a gravel bed stream (d
50 = 4 cm) with varying boulder-to-boulder spacing and the flows over the arrays were studied experimentally. The flow measurements were carried out by an acoustic Doppler velocimeter and the double averaging methodology (DAM) was applied. The results of large spacing boulder array reveals near-bed velocity deficit within 1Dc
upstream to 5Dc
downstream of the boulder and no influence on the approaching velocity was observed after 5Dc
corroborating the recovery of boundary layer. In case of medium and small spacing boulder array, the velocity deficit is significant at all locations. The shear stress distributions depict development of high and low bed shear stresses causing redistributions of the local bed shear stress. The higher magnitude of shear stress is observed at the boulder crest whereas; the secondary peak near the gravel bed crest is attributed to the skin shear stress on the individual boulder. Moreover, the present research contributes to our understanding that the boulder array on a rough bed stream leads to higher turbulent intensity at the boulder crest level.
Simplified dispersion analysis based on dye tests at a small stream
Authors: Říha Jaromír , Julínek Tomáš , Kotaška Stanislav
Published: August 2023

The modelling of solid transport in open channels requires good knowledge about parameters related to basic processes such as hydrodynamic dispersion, advection and decay rates. Such parameters are usually determined by dye tests. Numerous tracer studies have been performed on laboratory flumes and natural rivers. However, on-site sampling is often difficult, expensive and needs special apparatus. The main aim of the study was to justify simplified method based on the monitoring of the dye cloud shape in order to determine both longitudinal and transversal dispersion coefficients. In this study, four dye tests were carried out on a small local stream (the Lipkovsky) using Rhodamine WT fluorescein dye as a tracer. The tests were carried out in such a manner that both longitudinal and horizontal transversal dispersion data were obtained. For this purpose, the visually determined extent of the dye cloud was interpreted via the analytical solution of the advection-dispersion equation. The results obtained by this simplified approach indicated that the longitudinal dispersion coefficient Dx
= 0.051–0.057 m2/s and the coefficient of horizontal transversal dispersion Dy
= 0.00024–0.00027 m2/s. The method was justified by corresponding root mean square error (RMSE) counting RMSE = 0.65–1.02 m for the dye cloud centre, RMSE = 1.87–2.46 m for the head and tail of the cloud and RMSE = 0.025–0.11 m for the cloud width, the Nash-Sutcliffe efficiency coefficients ranged from 0.9 to 0.998. The comparison of these values with empirical formulae and other tracer studies indicated significant overestimation of the mentioned values of Dx
, which can be attributed to the uniform velocity distribution along the width of Lipkovsky Stream. Much better agreement was achieved for Dy

A Swan Lake: Exploring the Materiality of Water in Alexander Ekman’s Ballet
Authors: Ibarra Martina Cayul
Published: August 2023

This article analyses Ekman’s ballet A Swan Lake from the perspective of new materialism, which is understood as the agency of the non-human, particularly the role of water in the creation of movement and in the script of the ballet. The question guiding this article concerns how the materiality of water takes place in Ekman’s ballet. I propose that by paying attention to the corporeality of dance itself as a discursive practice (Barad 2003), it is possible to appreciate the creation of a kind of language or code that can be interpreted. Following Barad, a discursive practice not only is language or what is said but allows certain things to be said. Here, both the bodies of the dancers and the water allow things to be said. In other words, encounters of the materiality of the human, that is, the bodies of the dancers with the non-human agency of the water, provoke new ways of moving and therefore form part of the choreographic composition, thus co-creating the ballet itself.
Passing On—The Power of Oral Transmission
Authors: Öberg Anna , Ruth Charlotta
Published: August 2023

Living Documents is a series of looped live installations developed between 2017 and 2019 based on five artist-choreographers and how they work. The project was initiated by Dominik Grünbühel and Charlotta Ruth as an artistic response to the following research question: What is liveness and what can it be? The research was directed towards the necessity—but also difficulty—of documenting live performances. This text reflects how the method of passing on (in Swedish, tradera) through the collaborative process with choreographer Anna Öberg, whose practice is based in Swedish folk dance, has come to influence the documentary approach. By resonating how passing on in the cosmology of Folk Traditions is different to other methods of physical and oral transfer, Öberg together with Ruth develop how passing on can be valuable beyond the realm of Folk Tradition.

Specifically, they unfold the ways in which this multi-sensorial transfer of material and knowledge from person to person and context to context can inspire documentary and reflexive translations between media and different aesthetic realms and thereby contribute to creative ways of sharing knowledge in the field of artistic research.
Active Current Sensor Fault-Tolerant Control of Induction Motor Drive with Online Neural Network-Based Rotor and Stator Resistance Estimation
Authors: Adamczyk Michal , Orlowska-Kowalska Teresa
Published: August 2023

This article presents an active current sensor (CS) fault-tolerant control (FTC) strategy for induction motor (IM) drive with adaptation of rotor and stator resistances. The stator current estimator with online adaptation of resistance parameters was applied for the reconstruction of missing current signals. A model reference adaptive system (MRAS), based on a neural network (NN), was used to estimate the rotor resistance. Additionally, stator resistance estimation was applied based on ratio index. The use of such a solution allowed for a significant increase in the quality of stator current reconstruction, which is particularly important for the design of CS fault detection (FD) and compensation algorithms. A wide range of simulation studies have been carried out for different operating conditions of the IM drive. The results showed that applying rotor and stator resistance estimation can improve the quality of stator current estimation by up to approximately 95% under rated operating point. The study was carried out for nominal and low speeds, with two, one, and without healthy CS.

Approximation of Discrete Measures by Finite Point Sets
Authors: Weiss Christian
Published: August 2023

For a probability measure μ on [0, 1] without discrete component, the best possible order of approximation by a finite point set in terms of the star-discrepancy is &inline as has been proven relatively recently. However, if μ contains a discrete component no non-trivial lower bound holds in general because it is straightforward to construct examples without any approximation error in this case. This might explain, why the approximation of discrete measures on [0, 1] by finite point sets has so far not been completely covered in the existing literature. In this note, we close the gap by giving a complete description for discrete measures. Most importantly, we prove that for any discrete measures (not supported on one point only) the best possible order of approximation is for infinitely many N bounded from below by &inline for some constant 6 ≥ c> 2 which depends on the measure. This implies, that for a finitely supported discrete measure on [0, 1]d the known possible order of approximation &inline is indeed the optimal one.

Published: August 2023

Hybrid rice is derived from a cross between the cytoplasmic male sterile (CMS) as the female parent and the restorer line as the male parent. This study aimed to evaluate the ability of several new plant type (NPT) rice lines as restorers of the CMS female parent and to elucidate the performance of the hybrid combinations. The research was carried out from December 2019 to November 2020 at Babakan Sawah Baru Experimental Station, Department of Agronomy and Horticulture, IPB University, Bogor, Indonesia. The hybrids were evaluated in the field together with the CMS female parent, male parents, and two check varieties, namely Ciherang and hybrid P05 Prima Seed. The experimental design used was a randomized complete block design (RCBD) with two replications. The results showed that two male parental lines, IPB189-F-10-3-2 (T6) and IPB189-14-1-1 (T9), had a hybrid seed yield per hill of 66.04 g and 75.27 g, respectively. These two parents have the restorer gene (R) which is substantiated by the good characteristics of the number of filled grains and total grain per panicle of the two hybrids. The potential hybrids CMS x IPB189-F-10-3-2 and CMS x IPB189-14-1-1 had a positive heterosis for panicle length and 1,000 grain weight, and could be evaluated in future research.

Plasmodium kinases are increasingly recognized as potential novel antiplasmodial targets for the treatment of malaria, but only a small subset of these kinases have had structure-activity-relationship (SAR) campaigns reported. Herein we report the discovery of CZC-54252 (1) as an inhibitor of five P. falciparum kinases PfARK1, PfARK3, PfNEK3, PfPK9 and PfPKB. 39 analogues were evaluated against all five kinases to establish SAR at three regions of the kinase active site. Nanomolar inhibitors of each kinase are discovered. We identify common and divergent SAR trends across all five kinases, highlighting substituents at each region that improve potency and selectivity for each kinase. Potent analogues were evaluated against the P. falciparum blood stage. Eight submicromolar inhibitors were discovered, of which 37 demonstrated potent antiplasmodial activity (EC50 = 0.16 μM). Our results provide an understanding of features needed to inhibit each individual kinase and lay groundwork for future optimization efforts towards novel antimalarials.
Ultrafast Spectroscopy Reveals Slow Water Dynamics in Biocondensates
Authors: Lorenz-Ochoa Keegan , Baiz Carlos
Published: August 2023

Cells achieve high spatiotemporal control over biochemical processes through compartmentalization to membrane-bound, as well as membraneless organelles that assemble by liquid-liquid phase separation. Characterizing the balance of forces within these environments is essential to understanding their stability and function, and water is an integral part of the condensate, playing a nontrivial role in mediating the electrostatic and hydrogen bonding interactions. Here we investigate the picosecond hydrogen-bond dynamics of a model biocondensate consisting of a peptide Poly-L-Arginine and the nucleic acid adenosine monophosphate (AMP) using ultrafast two-dimensional infrared (2D IR) spectroscopy. We investigate three vibrational modes, the arginine side chain C=N stretches, an AMP ring mode, and the amide backbone carbonyl stretches, to provide different perspectives. In general, dynamics slow down considerably between the dilute phase and the condensate phase for each vibrational probe. For example, the arginine side chain C=N modes slows from 0.38 ps to 2.26 ps due to strong electrostatic interactions. Hydrogen bond lifetime computed from all-atom molecular dynamics simulations provide an atomistic interpretation. Simulations predict that a significant fraction of water molecules are highly constrained within the condensate. We attribute this slowdown in dynamics to a highly disordered and extremely crowded water environment.
Photoredox-catalyzed α-Scission vs β-Scission of PR3-OH Radicals: Synthetic Utilizations and Mechanistic Studies

Published: August 2023

Photoinduced generation of phosphoranyl radicals offers a versatile strategy to access a variety of synthetically valuable radicals, which has opened exciting new opportunities for radical manipulations and synthetic chemistry. While β-scission mode of phosphoranyl radicals has been intensively studied and broadly utilized via deoxygenation or desulfurization processes, a long-standing challenge still remains in the regulation of phosphoranyl radical to undergo α-scission pathway by overcoming the inherent driving force to generate the stable phosphine oxide via β-scission, which has been largely unexplored and rarely applied. We herein developed an unprecedented protocol to switch the fragmentation patterns between α- and β- scission of the generated phosphoranyl radicals under photocatalytic conditions. The success of our strategy presumably relies on finely tuning the reactivity of the crucial P(OH)R3 radical by altering the R substituents, and this P(OH)R3 radical intermediate is ultimately from water and tertiary phosphine reagent. Notably, the synthetic utility of both fragmentation patterns of the P(OH)R3 radical were well demonstrated via selective hydroalkylation or hydrogenation transformations of alkenes. A combination of experimental and computational studies was carried out to understand the reaction mechanisms.

In this paper, I present a course structure that focuses on scaffolding with student empowerment, growth, and success at the forefront of the design. I also present options for program assessment that focuses on skills and competencies as outcomes. Each instructor and program should consider their own values, outcome goals, and the context of the student body and university when designing assessments.
Challenges experiences by students during Study Abroad: Implications for Family Science faculty
Authors: Taylor Sarah , Brown Tiffany L. , Medora Nilufer
Published: August 2023

Family science literature has documented the benefits of studying abroad on students’ overall development. However, research has focused less on the challenges that students experience while studying abroad. This study aimed to explore the challenges family science students experienced in a semester-long study abroad program. Qualitative data were collected from 80 students participating in the Semester at Sea study abroad program. Participants responded to an open-ended survey question. Researchers used qualitative content analysis techniques to analyze data and identify common themes. Six major themes emerged from the data. Students experienced: 1) cognitive challenges; 2) social challenges; 3) academic challenges; 4) cultural challenges; 5) logistical challenges, and 6) emotional challenges. Students reported challenges across a variety of domains during the study abroad voyage. Understanding these challenges experienced by students may help family science faculty know where study abroad students can be further supported. Faculty should emphasize students’ cognitive preparations and support students in processing their experiences throughout their study abroad program. Faculty should also prepare students to return home and manage the guilt they may experience.

When Tomorrow Comes: contextualising the independent review of Tomorrow’s Schools
Authors: Barker Michael
Published: August 2023

The Tomorrow’s Schools reforms in 1989 fundamentally changed primary and secondary schooling in New Zealand. While the devolved nature of Tomorrow’s Schools has enabled higher levels of local autonomy, it has also been criticised for opening up schools to marketisation and contributing to inequality between schools. Around 30 years after the original reforms, a significant government-sponsored review was undertaken into whether the compulsory schooling system was still fit for purpose under the Tomorrow’s Schools settings. This article finds that there is a mismatch between the recommended structural reform and the resulting ‘reset’ of Tomorrow’s schools.

There has been a lack of research regarding endometrial stem cells in farm animals, and particularly, regarding epithelial stem/progenitor cells. We aimed to identify potential stem cell subpopulations in porcine and bovine endometrium by measuring the expression of selected stem cell markers (OCT3/4, CD44, SSEA-1, SOX10, CD73, and CD117) during the follicular and luteal phases of the oestrous cycle. We studied 28 endometrial tissue samples collected from 14 healthy, cycling pigs and cows. The endometrial mucosa of each sample was divided into basal, middle, and luminal portions, and the immunohistochemical staining intensity and percentages of cells that were marker-positive were recorded for each portion of the endometrium. Expression of OCT-3/4 was identified in the glands and stroma, and that of SOX10 and CD117 was identified in stroma of both porcine and bovine endometrium. In porcine endometrium, CD44 was only expressed in the glands, whereas SSEA-1 was expressed in the glands and stroma. In bovine endometrium, CD73 was only expressed in the glands. Differences in the expression of most of these markers were found between phases of the oestrous cycle and/or portions of the endometrial mucosa. Our data indicate the existence of both epithelial and mesenchymal stem cell subpopulations in the endometrium of pigs and cows during their oestrous cycles. The expression pattern of the stem cell marker SSEA-1 in porcine endometrium suggests a possible alternative location of the epithelial stem/progenitor cell population in the middle portion of the endometrial glands.

Qələbə qazanmaq üçün ehtiraslı arzu həmişə özünə inam, güclü iradə və inkişaf etmiş özünü təşkil etmək və özünü idarə etmək qabiliyyəti ilə dəstəklənir, bu, xüsusilə bərabər və ya üstün rəqiblə mübarizənin çətin vəziyyətlərində rəqiblər üçün zəruridir. Qələbə heç vaxt zəiflərə gəlmir, bu, özlüyündə təsadüfi deyil, lakin gözlənilməz qəza qələbənin əldə olunmasına mane ola bilər və ya əksinə, onu daha zəif rəqibə bəxş edə bilər.
TÜRKİYƏ XARİCİ SİYASƏTİNİN METOD VƏ YANAŞMA ANLAYIŞLARINA ÜMUMİ BİR BAXIŞ

Xarici siyasət araşdırmasının dəqiq və öyrədici nəticələrə çatması üçün ilkin mənbələrlə işləmək, məsələn ölkənin imzaladığı beynəlxalq sənədləri oxuyucuya təqdim etmək bəzən kifayət etmir.Statistik göstəricilərdən asanlıqla yalnış istiqamətə yönələ bilərsən. Bu zaman bir araşdrımacı hekayəni qurarkən istifadə edəcəyi üsul və yanaşmalar iki əsas məqsədə yönəlməlidir. Birincisi məsələnin mahiyyətini qavramaq, ikincisi bu mahiyyəti obyektiv şəkildə ortaya qoymaqdır. Bütövlükdə xarici siyasəti qavrayışının anlaşılması üçün müxtəlif metod və üsullardan istifadə edilməsi geniş yayılmışdır. Türkiyə xarici siyasətinin araşdırarkən onun özünəməxsus bir fenomen çərçivədə tədqiq edilməsi lazımdır. Osmanlı imperiyası ilə Türkiyə cumhuriyyəti arasında oxşarlıqlar və kəskin fərqlər bu iki dövlətin xarici siyasətində də özünü göstərmişdi. Eyni coğrafiyada, eyni xalqla birbirinin davamı olaraq qurulmuş “Orta dövlət” olmanın ortaq xüsusiyyətləri nəticəsində bu iki dövlətin xarici siyasətindəki oxşarlıqlar diqqəti çəkir. Hər ikisi öz mövcudluğunu müəyyən olunmuş iki əsas prinsip üzərindən aparmağa çalışıb. Böyük ehtiyatla qüvvələr nisbətinə riayət edərək ayaqda qalmaq və əks halda işğal təhlükəsi yoxdursa dövlətlər arasında müharibələrə girməməkdən ibarətdir.
Polis Amefricana:
Authors: Alves Jaime Amparo , Vargas João da Costa
Published: August 2023

A polis latino-americana é uma disposição geo-ontológica antinegra. O termo América e suas derivações estão enraizados no genocídio colonial e suas manifestações contemporâneas. Não se trata somente do papel das ‘elites criolas’ mas principalmente de um inconsciente coletivo planetário que constrói e reflete o que se convencionou chamar de América Latina não apenas em oposição à Europa, mas principalmente em oposição à negritude e aos corpos, culturas, epistemologias, e territórios associados a ela. Recusando estabelecer comparações, e sem ambições de oferecer uma leitura hemisférica, o artigo se propõe a discutir, a partir de uma perspectiva relacional, os limites de Américas, como comunidade política e modo de sociabilidade fundado na anti*negri*cidade constitutiva do projeto de latinidade.
Racismo à brasileira:
Authors: Véras Maura Pardini Bicudo
Published: August 2023

Este artigo pretende analisar o peso do racismo à brasileira, utilizando os termos de Munanga (2017) ao apontar que é um crime perfeito, pois apesar da negação de se assumir racista, seus efeitos são reais e evidentes; analisam-se as repercussões espaciais do racismo que não se assume como determinante das profundas desigualdades sociais presentes no país, deixando ao mercado de terras e habitações a regulação do acesso ao ambiente construído adequado. Resultam disso territórios da precariedade, expulsão e nomadismo urbano, em processos de relegação e social e racial. As chamadas periferias, em sua heterogeneidade, têm merecido um olhar contemporâneo e cuidadoso na apreensão das relações de alteridade do cotidiano multifacetado da vida urbana, na territorialidade possível, nos deslocamentos pendulares ou esporádicos, na busca do trabalho, cultura e reconhecimento de sua cidadania, no sofrimento ético-político dos sujeitos que habitam tais regiões.
Estado da Arte nos estudos e pesquisas sobre Cidades, Urbanização e Relações Étnico-Raciais, e Enunciados sobre o Dossiê Cidades Negras no Brasil e nas Américas

Published: August 2023

O presente texto tem como objetivo apresentar o estado da arte sobre a cidade, a urbanização e as relações étnico-raciais no Brasil, em especial, as pólis e os territórios negros. Posteriormente, apresentamos os textos que constituem o dossiê, Cidades Negras nas Américas: a produção de políticas de enfrentamento ao racismo. Por último, é urgente a produção de ensino, pesquisa e extensão sobre as cidades brasileiras com ênfase nas relações étnico-raciais, como as urbes de grande, médio e pequeno portes, porque a população africana e afro-brasileira, durante os 388 anos do escravismo, fundou cidades, bairros e territórios com a sua força de trabalho e em toda a paisagem natural desenvolveu a produção social do espaço. No decorrer dos últimos 135 anos, da pós-abolição aos dias de hoje, foi exatamente a força de trabalho africana e afro-brasileira, por intermédio da cultura e da organização dos territórios de luta por direitos, que proporcionou o quadro atual do desenvolvimento no Brasil e nas Américas.

Este estudio analizó la relación entre indicadores de riesgo para la salud y los componentes del somatótipo según los niveles de actividad física en niños. Se trata de una investigación epidemiológica, compuesta por 168 niños (6 a 11 años) de ambos sexos. Fueron mensuradas: evaluaciones antropométricas (estatura; masa corporal; pliegues de adiposidad subcutánea; perímetros del brazo contraído, cintura, cuadril y pantorrilla), presión arterial sistólica y diastólica, y actividad física (activo/inactivo); el somatótipo, a través del cálculo de: razón cintura-cuadril y razón cintura-estatura. Se realizó el análisis de comparación, correlación y regresión lineal múltiple, considerando intervalo de confianza del 95%. Los niños presentaron mayor número de pasos, razón cintura-cuadril y cintura-estatura. Los niños activos eran mayores, tenían mayor perímetro de cintura, cuadril y presión arterial sistólica. En el grupo físicamente activo, el sexo estuvo asociado directamente al perímetro de cintura y razón cintura-estatura, mientras que la edad se asoció con el perímetro de cuadril y presión arterial diastólica. En los niños inactivos, todas las variables predictoras (excepto para la variable sexo con relación al perímetro de cuadril) se mostraron significativas para el perímetro de la cintura y cuadril, explicando, conjuntamente, ~83% y 85% de la expresión de estas variables, respectivamente. La relación entre indicadores de riesgo para la salud y los componentes del somatotipo fue mayor en niños inactivos. Independientemente del nivel de actividad física, la endomorfia mostró una relación significativa con los componentes de salud, con mayor efecto en el grupo inactivo, con vistas a la asociación con la composición corporal de los sujetos.

ON THE IMPROVEMENT OF MEASURES FOR THE PROTECTION OF MINORS IN THE EVENT OF A THREAT TO THEIR LIFE AND HEALTH IN FAMILY RELATIONS
Authors: Aseeva Kristina , Timoshina Elena
Published: August 2023

The article touches upon the existing problem of legal regulation of the protection of minors in the event of a threat to their life and health in family and domestic relations. The article considers the practice of illegal removal of children from parents as a result of the application by the guardianship and guardianship authorities of Article 77 of the Family Code of the Russian Federation, which regu-lates the removal of a child from his parents (one of them) or from other persons in whose care he is with a direct threat to his life or health.

As a way to solve these problems, it is proposed to amend the current legislation, providing for the introduction of the institution of "temporary measures to protect the child", which ensures the prompt solution of the problem of protecting a minor who is without supervision and assistance in a situation that threatens his life.
