Authors: Deng Yu , Fan Anhui 
Published: October 2022

BackgroundAlthough changes in overall physical activity (PA) have been identified in adolescents, the trend in sports participation is still understudied. It is widely believed that monitoring the changes in sports participation is conducive to promote the development of sports activities. The purpose of this research was to identify the changes in sports participation in adolescents over the past years.MethodsThis research selected secondary data from 2011, 2013, 2015, 2017, and 2019 Youth Risk Behavior Surveillance (YRBS). Logistic regression models were applied to discuss and analyze the secular changes across the years of data. The change differences in sports participation by sex, grade, and race/ethnicity were also explored via separate logistic regression.ResultsA declined overall trend could be observed in sports participation in adolescents, the prevalence of sport participation was 58.4% in 2011 and 57.4% in 2019. The declining trend was also observed in grades 10 (62.3% in 2011 and 57.9% in 2019) and 12 (52.5% in 2011 and 49.8% in 2019) adolescents, and an increase could be observed in grade 11 (56.2% in 2011 and 59.1% in 2019) adolescents, but few changes were found in grade 9 (61.4% in 2011 and 61.9% in 2019) adolescents. Only white adolescents reported an increasing prevalence of sports participation, slight declines in sports participation were observed in black or African American, Hispanic/Latino, and other adolescents.ConclusionsThe declining trend in sports participation could be seen in adolescents between 2011 and 2019, but it should also note that large variations of trends in sport participation by subgroups were also found.

Published: October 2022

Objectives and Methods: A cross sectional study of HCPs working in public MCH clinics in Assiut city was conducted to explore their knowledge, attitudes and counselling practices regarding prevention of SHS exposure among pregnant women and children. Descriptive and regression analyses were performed.Results: 367 HCPs participated in the study, 12% of whom were smokers. The majority were nurses (45%). A considerable proportion of HCPs reported being exposed to SHS in workplace (70%) and home (52%). About half HCP reported high SHS knowledge (56%), supportive attitude towards preventing SHS exposure (53%), and having good counselling practice regarding SHS exposure (52%). Being a GP and serving urban communities were significantly associated with high knowledge. Being female, serving a rural population, receiving training on smoking cessation services, not being exposed to SHS at home, and having a supportive attitude towards prevention of SHS exposure were significantly associated with good counselling practice.Conclusion: Awareness, attitudes and counselling practice of HCPs should be improved. Training for HCPs and enforcement of smoke free polices are needed to improve awareness and facilitate changes in social norms.

Цель исследования - изучение гематологических показателей и анализ их взаимосвязи с различными параметрами композиционного состава тела у долгожителей с ИБС. Данная работа - одномоментное («поперечное») исследование, в которое были включены 239 больных старше 90 лет, госпитализированных с диагнозом ИБС; большинство из них (67,8%) составили женщины. Возраст пациентов колебался от 90 до 106 лет, составляя в среднем 92,8 года (±2,5 года). Композиционный состав тела анализировали посредством двухэнергетической рентгеновской абсорбциометрии. У 108 (45,2%) больных была выявлена анемия, при этом обнаружена достоверная прямая корреляция уровня гемоглобина и всех показателей минеральной плотности костной ткани ( р =0,004-0,00002). У пациентов с остеопорозом отмечен более низкий уровень гемоглобина ( р =0,002) и железа крови ( р =0,02). Установлены прямые корреляции уровня гемоглобина и содержания тощей ткани ( р =0,06-0,003). У больных с ожирением выявлен более высокий уровень гемоглобина ( р =0,007), эритроцитов ( р =0,03), лейкоцитов ( р =0,04), лимфоцитов ( р =0,01) и моноцитов ( р =0,05). Зарегистрирована прямая корреляция числа тромбоцитов и показателей жировой ткани ( р =0,04-0,00006) наряду с обратной корреляцией тромбоцитов и тощей ткани ( р =0,001-0,0004). Полученные результаты свидетельствуют о значимых взаимосвязях параметров композиционного состава тела, с одной стороны, и гематологическими показателями - с другой.
The study objective to investigate hematological parameters and determine the relationships between these indicators and body composition in centenarians with coronary artery disease. This work is a cross-sectional study, which enrolled 239 patients over 90 years old hospitalized with a diagnosis of coronary artery disease; most of them (67,8%) were women. The age of the patients ranged from 90 to 106 years, averaging 92,8 (±2,5) years. Body composition was analyzed by dual energy X-ray absorptiometry. Anemia was detected in 108 (45,2%) patients, while a significant direct correlation was found between the hemoglobin level and all indicators of bone mineral density (p=0,004-0,00002). Patients with osteoporosis had lower levels of hemoglobin (p=0,002) and blood iron (p=0,02). Direct correlations were established between the hemoglobin level and lean tissue mass (p=0,06-0,003). Patients with obesity had higher levels of hemoglobin (p=0,007), erythrocytes (p=0,03), leukocytes (p=0,04), lymphocytes (p=0,01) and monocytes (p=0,05). A direct correlation was registered between the platelets count and fat tissue mass (p=0,04-0,00006) along with an inverse correlation between platelets and lean tissue (p=0,001-0,0004). The study results indicate significant relationships between the parameters of body composition and hematological indicators.

Проведено проспективное исследование, включившее 92 пациента старше 70 лет с инфарктом миокарда. Всем пациентам проводили выявление и определение тяжести гериатрических синдромов, в том числе синдрома старческой астении, с использованием специализированных шкал на 5-е сутки госпитализации. Оценивали коморбидный фон с расчетом индекса Чарлсон, уровень NT-proBNP, ST-2, FGF-21, VEGF в сыворотке крови методом ИФА. В обследуемой когорте пациентов установлена выраженная коморбидность, высокая распространенность преастении и астении в сочетании с другими гериатрическими синдромами. У пациентов старше 70 лет с инфарктом миокарда и синдромом старческой астении выявлен достоверно более высокий уровень миокардиального стресса и фиброза, чем у той же категории пациентов без синдрома старческой астении, что является прогностически неблагоприятным признаком. Уровень NT-proBNP и ST-2 значимо коррелировал с основными гериатрическими синдромами и может являться маркером развития синдрома старческой астении у пациентов пожилого и старческого возраста с инфарктом миокарда.
A prospective study of 92 patients over 70 years old with myocardial infarction was carried out. All patients were diagnosed and determined the severity of geriatric syndromes, including fragility, using specialized scales on the 5th day of hospitalization. The comorbidity was assessed with the calculation of the Charlson Comorbidity Index, levels of NT-proBNP, ST-2, FGF-21, VEGF in blood serum by enzyme immunoassay. In the studied cohort of patients, marked comorbidity, high prevalence of prefragility and fragility in combination with other geriatric syndromes were revealed. Patients over 70 years old with myocardial infarction and fragility showed significantly higher levels of myocardial stress and fibrosis, which is prognostically unfavorable sign for the given group of patients. NT-proBNP and ST-2 levels have significant correlation with major geriatric syndromes and could be the markers of fragility development among elderly and senile patients with myocardial infarction.

Pedagogical algorithm for the development of professional competence of employees working with convicts - former law enforcement officers
Authors: Pashukova Anastasiya 
Published: October 2022

Abstract. The relevance of the study is due to the fact that highly qualified personnel are needed for the productive functioning of the penal system. Employees of the penal system should not only have specific professional knowledge, skills and abilities, but also be sociable, since the basis of their official activity is pedagogical communication aimed at correcting convicts of various categories.
To ensure successful professional activity, employees working with convicts – former law enforcement officers need to have a high level of professional competence. In order to solve this problem, a pedagogical algorithm for the development of professional competence of employees was developed, which is a set of sequential actions aimed at achieving results, namely, increasing the level of formation of professional competence of prison staff. The main research methods are modeling, conversation, testing, and the method of expert evaluation.
The importance of gradual formation of professional competence in the correctional system is emphasized. The pedagogical algorithm for the development of professional competence of employees of specialized establishments consists of four main stages (initial, diagnostic, organizational developmental, effective). The strict sequence of the algorithm implementation will help to improve the efficiency of the professional activities of employees in correctional institutions for the detention of convicts – former law enforcement officers.
In the course of the research, the algorithm proved its effectiveness, since after its implementation there is an increase in the level of formation of professional competence of employees of a specialized institution.
The obtained results showed that the effectiveness of activities for the re-socialization and correction of convicts of various categories directly depends on the professionalism of correctional staff.
