Research of the application of elements of sports games in the process of therapeutic physical education activities

Recent studies have shown that the use of elements of team sports in physical education classes in a special medical group “B” (therapeutic physical education) remains one of the promising areas and, at the same time, a rather complex methodological problem, caused in many cases by concomitant diseases of students. When discussing the features and advantages of various team sports in the mode of practical exercises in therapeutic physical culture in universities, it is necessary to pay attention to the differentiated use of elements of sports games in accordance with the existing pathology.Purpose. Determine the most effective complexes of physical activity using elements of team sports.Materials and methods. The material for the work was the results of a current medical examination, motor tasks that make it possible to determine the level of development of physical qualities, and data from a functional test. The research was conducted at the departments of physical education of Astrakhan State Medical University and Kuban State Medical University and Astrakhan State University in the 2021/22 academic year. Based on functional tests, the level of physical fitness of those involved was analyzed, and hemodynamics were determined during physical activity classes using elements of team sports. The work used standard methods of mathematical analysis.Results. A reliable correlation was revealed between the use of elements of team sports and the level of increase in the regulatoryadaptive potential of the cardiovascular system, reduction of BMI, elements of team sports were identified that are advisable to recommend for the appropriate medical group. During the work, data were obtained on the effectiveness of using elements of sports games for students assigned to medical group “B”.Conclusions. It is advisable to use elements of basketball in the form of developing coordination abilities, mastering techniques of ball possession with changing parameters in space and time interval. In our opinion, this format allows you to vary the intensity of physical activity in accordance with the level of functional and physical fitness of students. In the same group, it is possible to use elements of volleyball and the game of volleyball itself according to simplified rules. The individual duration of rest breaks should allow the cardiorespiratory system to be restored to background levels.

Overtime work is related to nonrestorative sleep independently of short sleep time among a Japanese occupational population.

The symptoms of insomnia are defined as difficulty falling asleep, difficulty staying asleep, and early awakening. Although also a symptom of insomnia, nonrestorative sleep (NRS) is clearly more associated with objective indices than other insomnia symptoms. However, the link between NRS and overtime work duration is poorly understood. The results of a single year's medical examinations were investigated for 26,144 Japanese office workers who were 30 to 59years old. NRS status and lifestyle were collected through a computer-assisted medical interview. The subjects were asked about the presence or absence of NRS and their lifestyles in the most recent two to three months. The subjects were asked about their sleep times and average overtime durations per month (< 20h/month, ≥ 20 but < 40h/month, ≥ 40 but < 60h/month, and ≥ 60h/month). The relationships between NRS and overtime work duration adjusted for sleep time were also analyzed. The proportion of subjects with NRS showed a stepwise increase as overtime work hours increased. A logistic regression analysis was performed using NRS as an objective variable. The multivariate analysis demonstrated that overtime work duration (OR, 1.13; 95% CI 1.10-1.17; P < 0.001; per one-category increase) was an independent determinant of NRS. For office workers, long hours of overtime work increased the NRS prevalence at any sleep duration.

Results of preventive medical examinations of children in Donetsk People’s Republic, Luhansk People’s Republic, and Zaporizhzhya and Kherson regions

BACKGROUND: The preventive direction of medicine has become increasingly popular in recent years. The government has paid much attention to the health of the population and preventive examinations. Among the main priorities of the state, the health of the pediatric population remains a guarantee of a healthy nation.&#x0D; AIM: To assess the health status of the pediatric population of the new territories of the Russian Federation and develop measures to further improve medical care at the regional level.&#x0D; MATERIAL AND METHODS: The study enrolled children aged 017 years living in the new territories of the Russian Federation, namely, the Donetsk Peoples Republic, Luhansk Peoples Republic, Zaporozhye oblast, and Kherson oblast. A total of 32 teams of specialists from 30 territories of the Federation have been formed to conduct in-depth preventive medical examinations of the pediatric population of these new territories.&#x0D; RESULTS: The study participants were predominantly children aged 014 years. The overall morbidity in all regions was dominated by diseases from the five classes according to ICD-10, namely, diseases of the musculoskeletal system and connective tissue; endocrine, nutritional, and metabolic diseases; of the eye and adnexa; and disorders of the nervous system, respiratory system, and psychological development. Half of the study participants were diagnosed with a disease for the first time in their lives.&#x0D; In the Russian Federation, the high proportion of healthy children is due to the contingent of the child population, and the third group of health with better detection of diseases due to the in-depth nature of preventive medical examinations. The distribution into groups for physical education corresponded to health groups. According to the preventive medical examinations results, more than a third of the total number of examined children was transferred to dispensary supervision. Emergent and urgent cases and mental disorders require measures under stable conditions.&#x0D; CONCLUSION: The results of the preventive medical examinations can be the basis for subsequent therapeutic, diagnostic, and rehabilitation work by medical organizations and preventive and health-improving activities by educational institutions.

What do we Know about Flat Feet?

This question may seem strange to physicians, but how will they explain that in the forties of the last century, flat feet were tested only in 4-6% of the population, and in 2000, according to the results of a general medical examination conducted in Russia, deformities of the feet and spine were already noted in 85-95 % of the population.

Forensic medical cytological examination of the trace evidence on the knife’s blade in the case of multiple penetrating stab/cut wounds in the chest with lung damage: a case report

Various trace evidence are often found on the instruments of mechanical injury, including microparticles of humans damaged organs and tissues. The detection of cells and microparticles of organs and tissues on the instrument of injury confirms its contact with the human body, which is of great evidentiary value.&#x0D; The article presents the results of forensic medical cytological examination of biological evidence taken from the knifes blade in the case of multiple penetrating stab/cut wounds in the chest that result in lung damage. Microscopic preparations were made from the traces on knifes blade, which were stained with fluorochrome solutions (0.0005% aqueous solution of atebrine and 0.01% solution of acridine orange). The study was performed using the luminescent microscope Leica DM2500 (20 and 60 lenses, 10 eyepiece). The examination of microparticles of the striated skeletal muscle revealed areolar connective and fat tissues with capillary and arteriole fragments. The isolated mesothelial cells and type II pneumonocytes were also detected. Fibers of the striated skeletal muscle tissue looked like long multinucleated cells with distinguishing cross-striation. The areolar connective tissue was represented by loosely arranged fibers embedded in the ground substance. Fragments of the fat tissue looked like the clusters of round and oval large cells, tightly pressed together, with capillaries, and arterioles in between. Y-chromatin was detected in the nuclei of most cells. In addition, human blood was found on the knifes blade.&#x0D; Thus, the study revealed that tiny particles of tissues and isolated human cells of the male genetic sex were detected, their organtissue affiliation was established, which is a valuable diagnostic finding, because it confirms the contact of the trauma instrument with the human body.

The study was carried out on the basis of written informed consent from the subjects. The study included two stages: an assessment of the neurocognitive status of the subjects (Montreal Cognitive Function Assessment (MoCA) and an experimental study of fixations of oculomotor reactions during the perception of addictively significant stimuli (the hardware complex for assessing oculomotor reactions Tobii EyeX and the GazeControll software). &lt;strong&gt;Results.&lt;/strong&gt; Specific features of fixations of oculomotor reactions during the perception of addictively significant stimuli by patients with alcohol dependence make it possible to typify the strategies of oculomotor reactions. on an empty background field outside the depicted objects) may be due to the actualization of a pathological craving for alcohol caused by the demonstration of addictively significant stimuli.&lt;/p&gt;

Study on risk factors of diabetic peripheral neuropathy and establishment of a prediction model by machine learning

BackgroundDiabetic peripheral neuropathy (DPN) is a common complication of diabetes. Predicting the risk of developing DPN is important for clinical decision-making and designing clinical trials.MethodsWe retrospectively reviewed the data of 1278 patients with diabetes treated in two central hospitals from 2020 to 2022. The data included medical history, physical examination, and biochemical index test results. After feature selection and data balancing, the cohort was divided into training and internal validation datasets at a 7:3 ratio. Training was made in logistic regression, k-nearest neighbor, decision tree, naive bayes, random forest, and extreme gradient boosting (XGBoost) based on machine learning. The k-fold cross-validation was used for model assessment, and the accuracy, precision, recall, F1-score, and the area under the receiver operating characteristic curve (AUC) were adopted to validate the models’ discrimination and clinical practicality. The SHapley Additive exPlanation (SHAP) was used to interpret the best-performing model.ResultsThe XGBoost model outperformed other models, which had an accuracy of 0·746, precision of 0·765, recall of 0·711, F1-score of 0·736, and AUC of 0·813. The SHAP results indicated that age, disease duration, glycated hemoglobin, insulin resistance index, 24-h urine protein quantification, and urine protein concentration were risk factors for DPN, while the ratio between 2-h postprandial C-peptide and fasting C-peptide(C2/C0), total cholesterol, activated partial thromboplastin time, and creatinine were protective factors.ConclusionsThe machine learning approach helped established a DPN risk prediction model with good performance. The model identified the factors most closely related to DPN.

First-round accreditation and pass rates on licensing examination at different medical schools in China: Closing the performance gap.

Although the accreditation approach is widely used to ensure the quality of medical education in many countries, there is scant empirical evidence on whether and how it improves actual medical school performance. We focused on conditions in China, which introduced an accreditation system during the 2010s. Specifically, we examined the relationship between first-round accreditation and actual performance based on the results of medical licensing examinations. Referring to organisation theory, we hypothesised that the impacts of accreditation would depend on existing performance gaps. In 2022, we analysed panel data from 105 Chinese medical schools during accreditation (2012 to 2021) and pass rates on medical licensing examinations (2011 to 2019), as matched into 834 school-year records in a window of years before and after accreditation. We employed fixed-effects regression models with a comparison group to exclude factors that may have confounded the impacts of accreditation time. We also demonstrated the heterogeneous effects of accreditation by tier and performance gap of medical schools. The conservative estimates showed a substantial cumulative improvement (over 15 percentage points) in pass rates during the years before accreditation, with no clear trend indicating performance drops in the years after accreditation. Lower-tiered medical schools gained greater benefits from accreditation. Medical schools with a larger prior performance gap achieved a greater percentage point increase in pass rates with the passage of time in pre-accreditation years. This is the first empirical study to investigate whether accreditation has bridged performance gaps among medical schools. The results support the value of accreditation in China, a country that recently established the system, and might work as a substitute for missing information on early accreditation history in countries with long-established accreditation systems. We encourage more studies in countries that have recently introduced accreditation systems.

Purpose, subject matter and objectives of forensic medicine

It has been established that forensic medicine is a branch of medicine that deals with the application of medical knowledge and methods to resolve legal issues, in particular those related to death, injury and other types of violence. The main purpose of forensic medicine is to examine the bodies of the dead or injured in order to determine the cause of death or injury, as well as to determine the possible criminal element in the act. To do this, forensic physicians use methods of body examination, evidence collection and expert analysis.&#x0D; It has been generalised that forensic medical examination as a subject of forensic medicine is a scientific and practical research carried out by specially trained specialists with the aim of providing an objective assessment of medical issues in cases brought before a court. This examination may include determining the causes and circumstances of death, assessing injuries, determining the severity and possible consequences of injuries, examining the patient's medical history, and other medical issues that may be relevant to the resolution of court cases. The results of a forensic medical examination may be used as evidence in a court of law.&#x0D; It has been stated that the main tasks of forensic medicine as a branch of science are: study of human physiology and pathology, as well as the relationship of these processes with the knowledge of the cause of death and other traumatic injuries; development and improvement of methods for detection and assessment of traumatic injuries and their consequences, as well as establishment of the relationship between trauma and health consequences; detection of the impact of physical and chemical factors on human health, as well as establishment of the causes and consequences of the impact of these factors; determining the state of human health in the context of criminal investigation, including assessment of the state of alcohol or drug intoxication and its impact on human behaviour and actions; studying the relationship between the state of health and the crime committed, as well as establishing the facts of the presence and nature of injuries of victims.

Occupational health issues and respiratory toxicity of a complex of harmful factors in electrolytic and hydrometallurgical copper production

Introduction. In recent decades, there has been a decrease in occupational morbidity at enterprises producing rough and refined copper, in the structure of which, nevertheless, bronchopulmonary pathology retains a leading position.The aim is to study the occupational risk of developing respiratory pathology in workers engaged in obtaining cathode copper by electrolysis and electorowinning methods, based on the study of working conditions of workplaces and clinical observation.Materials and methods. The object of the study were: Uralelectromed, V. Pyshma (UEM); Uralhydromed, Polevskoy (RMK). The subject of the study were 100 employees of the electrolysis shop of UEM – the 1st observation group; 102 people of the auxiliary workshops of UEM – the 2nd observation group; 92 workers of the extraction and electorowinning department of UGM – the 3rd observation group.Results. During electrolytic refining of copper, the leading harmful factors with respiratory toxicity are sulfuric acid aerosol, selenium dioxide, nickel, arsenic, and during electrovinig – sulfuric acid aerosol. Violations of ventilation function and pulmonary gas exchange were observed in 21.0 % of cases in persons of the 1st and in 15.7% of cases in patients of the 3rd observation group).Discussion. Changes in the function of external respiration (FVD) were established mainly by the obstructive type, namely, an increase in RV, FRC and RV/TLC and a decrease in FEV1, VC, FEV1/VC, FEV25-75 of mild and moderate severity were noted. The bronchodilation test revealed the reversibility of bronchial obstruction in both groups 1 and 3. Obstructive disorders and dynamic hyperventilation of the lungs in copper refining workers are probably a consequence of hyperreactivity of the bronchi in response to the irritating properties of sulfur-containing gases, arsenic and nickel compounds.Conclusion. The results of the study indicate respiratory toxicity of harmful factors in workers of electrolysis and electrovining, which corresponds to a high and average occupational risk of class 3.3 and class 3.2 assessment of working conditions and the results of mandatory periodic medical examinations.

The results of periodic and dispensary medical examination of Kursk Region population in 2022

Objective: to analysis of indicators of preventive medical examinations and dispenserization of the adult population of Kursk, districts and the Kursk region as a whole, development of medical and organizational measures to achieve planned indicators. Material and methods. Analysis of data from form 131 and copying of information from the summary reports of medical institutions by cluster analysis and grouping of indicators depending on the achievement of the plan, extensive indicators were calculated, the results are presented in bar charts. Results. All districts and cities of the Kursk region are divided into three clusters. The first cluster (at least one of the features must reach 100% fulfillment) included 6 districts. The second cluster (districts with the implementation of the plan from 50%) included 21 districts and three cities of the Kursk region. The third cluster (districts with the implementation of the plan up to 50%) included 1 district. Conclusion. The analysis made it possible to identify areas with a low level of completeness of coverage of the adult population with preventive medical examinations and dispenserization. In these areas, it is necessary to resume the work of volunteer detachments with the population to educate them in order to achieve the planned indicators.

Relationship between nonrestorative sleep and heartburn among a Japanese occupational population.

Nonrestorative sleep (NRS) is a symptom of insomnia and is clearly more associated with objective indices than other insomnia symptoms. Gastroesophageal reflux disease (GERD) and insomnia are known to be strongly related. However, the link between NRS and heartburn, a main symptom of GERD, is poorly understood. Therefore, the relationships between them were investigated in addition to sleep duration. The results of a single year's medical examinations were investigated for 29,475 Japanese active office workers who were 20 to 59years old. NRS and heartburn were investigated in a medical interview using a personal computer. The relationships between NRS and heartburn in addition to sleep duration were also analyzed. The subjects were 46.6 ± 8.7years old (mean ± SD) and 27% and 13% of them had NRS and heartburn, respectively. The presence of NRS together with a sleep duration of ≤ 5, 6, 7 or ≥ 8hours was an independent comorbid factor for heartburn compared with the absence of NRS together with a sleep duration of seven hours (reference; odds ratio [OR], 2.38; 95% confidence interval [CI], 2.11-2.69, OR, 2.44; 95% CI, 2.16-2.76, OR, 2.33; 95% CI, 1.94-2.79; and OR, 1.72; 95% CI, 1.14-2.52). The absence of NRS together with a sleep duration of ≤ 5hours was also an independent comorbid factor for heartburn compared with the reference (OR, 1.20; 95% CI, 1.05-1.37). NRS in active workers may contribute to heartburn comorbidity despite the sleep duration as in other workers without NRS.

The structure of detected kidney diseases based on the results of forensic medical examination of corpses

The structure of the detected kidney pathology was studied according to the results of a forensic medical examination of corpses in the St. Petersburg Bureau of Forensic Medical Examination (BSME) in 2020–2021. As a result of the research, it turned out that out of the total number of all corpses that were sent by the investigative bodies for forensic medical examination to the St. Petersburg Bureau of Forensic Medical Examination over the years, kidney pathology amounted to 0.7 %. The most frequent (67 %) renal pathology leading to death were malignant kidney diseases. In the group of malignant kidney diseases, the age of the deceased was in the range of 40–90 years (with a pronounced peak of 80–90 years). The age of the majority of those who died from non-malignant kidney diseases was 50-90 years (with a pronounced peak of 80-90 years). Gender differences in the causes of death in the groups of malignant and non-malignant kidney diseases have not been established.

Ultrasonography in the evaluation of various factors of developmental dysplasia of the hip in infants: Results from a retrospective study in a large hospital of northwest China

BackgroundThe occurrence and development of developmental dysplasia of the hip (DDH) are related to a variety of factors, which have been reported in the literature, but the literature does not mention factors related to the severity of DDH. The purpose of this study is to analyze the related factors of the occurrence and severity of DDH in combination with the Graf ultrasonic diagnostic classification. MethodsThis study was a monocentric retrospective study describing the factors associated with DDH in a large hospital of northwest China. A total of 3046 infants (6092 hips) within 6 months after birth using the Graf method were admitted to our department between 2014 and 2018. We analyzed data of DDH. After reviewing medical charts and diagnostic examination results, we assessed whether factors such as ethnicity, gender, gestational age, birth weight, diagnosis age, maternal age, mode of delivery, fetal presentation, amniotic fluid volume and birth order, had any effect on development of hip. Result① Analysis showed that DDH mostly occurs in female and left hip joint, related to intrauterine fetal presentation, amniotic fluid volume, gestational age, mode of delivery, prenatal weight, and diagnosis age after birth, and the occurrence of DDH is also related to maternal age (All P＜0.05). Ethnicity and first born showed have no obvious correlation with DDH incidence (p = 0.718, 0.147, respectively). ② The strongest correlation was found with amniotic fluid, followed by birth weight. ③ The severity of DDH was correlated with ethnicity, births, prenatal weight, gestational age, diagnosis age and maternal age (All P＜0.05, respectively). ④ There were significant differences in treatment methods, duration and prognosis among different types of DDH. ConclusionsThe occurrence and development of DDH are related to a variety of factors. Ultrasound examination can provide an early assessment of the hip development status of infants and may play an important role in establishing an early clinical diagnosis treatment and monitoring and prognosis.

Prediction of criminal profiles based on forensic medical investigations in Banda Aceh, Indonesia

Background: Criminal profiles are also often referred to as psychological profiles or engagement profiles. Profile means a description the term profile to be discussed when discussing techniques and determining the possible characteristics of the debate about the results of research on crime itself. The following paper aims to present the case in predicting criminal profiles in Banda Aceh Indonesia based on forensic medical investigations. Case presentation: The victim is a male 16-year-old which is conducted a forensic medical examination. The result of forensic medical autopsy findings is the destruction of face-forming bones and skull fractures in the victim. According to the autopsy finding, the doctor concluded that the violence was carried out by someone who is powerful. The doctor states that the alleged criminal's profile consists of someone close to the victim, someone likely to be male, and someone who engaged in violence by using blunt objects. The police investigator is an Indonesian National Police in Banda Aceh district who has done the interview. The discussion with police investigators was conducted to predict the alleged perpetrator's profile. Based on the doctor's statement, the police conducted an investigation looking for the suspect, and the doctor's prediction was correct about the criminal profile of the perpetrator. During the trial, the panel of judges stated that the perpetrators used blunt objects to attack the victim. Conclusion: There is an association between the results of forensic medical examination, police investigations and facts at the trial in predicting the profiles of criminals.

Topical issues of forensic medical examination in the investigation of war crimes

The relevance of the study is conditioned by the importance of expert investigations into war crimes committed on the territory of Ukraine. Since many of these crimes result in the death or injury of victims, forensic examinations play a key role in investigations under the Criminal Procedure Code. The purpose of the study was to update the significance of the results of forensic medical examination in proceedings on war crimes, and to identify problematic aspects of the appointment of such an examination simultaneously with proposals for ways to overcome them. The methodological basis of the study was general scientific (dialectical, analysis, synthesis, induction and deduction) and special methods (system and structural, comparative legal, formal logical). It is established that modern capabilities of forensic medical examination contribute to achieving the goal of pre-trial investigation of military torts in limited conditions of forming a high-quality evidence base for such proceedings. However, the effective use of the potential of forensic medical examinations is hindered by a number of problems caused not only by the consequences of active military operations, but also by shortcomings in the legal regulation of this type of forensic examination, imperfect organisation of the structure and functioning of forensic medical institutions during the time of emergency. Possible ways to overcome the identified difficulties are proposed: reorganisation of the structure of forensic medical institutions, in particular, by establishing a department for forensic examination of corpses within a mobile military hospital with the involvement of specially trained forensic experts; simplification of the procedure for processing documents where the results of external examination of the corpse are recorded; updating the regulatory support for the activities of forensic doctors during martial law. The practical significance of the study lies in the fact that the conclusions obtained will help expand the understanding of pre-trial investigation officers of the possibilities of forensic medical examinations in the investigation of war crimes, and will also help identify the problems arising when appointing such examinations and suggest ways to solve them.

Factors influencing the sperm retrieval rate of microdissection testicular sperm extraction in patients with nonmosaic Klinefelter syndrome.

To investigate the factors affecting the sperm retrieval rate of microdissection testicular sperm extraction (micro-TESE) in patients with nonmosaic Klinefelter syndrome (KS), 64 patients with nonmosaic KS who underwent micro-TESE in the Center for Reproductive Medicine of Peking University Third Hospital (Beijing, China) between January 2016 and December 2017 were included in the study. Data on medical history, physical examination and laboratory examination results, and micro-TESE outcomes were collected. Patients were divided into two groups according to micro-TESE outcomes. The following factors were compared between the two groups by the Mann ‒ Whitney U test or Student's t-test based on the distribution (nonnormal or normal) of the factors: age, testicular size, follicle-stimulating hormone level, luteinizing hormone level, testosterone level, and anti-Müllerian hormone level. The overall success rate of sperm retrieval was 50.0%. Correlation analysis showed that testicular volume was positively correlated with testosterone level. Using a logistic regression model, age and anti-Müllerian hormone levels were found to be better predictors for the sperm retrieval rate than the other parameters.

Cavernous sinus thrombosis as a cause of fatal outcomes in forensic medical practice

Cavernous sinus thrombosis is a life-threatening condition resulting from a blockage of the cavernous sinus by a blood clot. This pathology occurs extremely rarely but is a danger to life at any age. Information about deaths from cavernous sinus thrombosis is limited and unclear in the special forensic medical literature.&#x0D; This study analyzed the results of the forensic medical examination of the corpse of a 35-year-old woman. This work outlines all stages of treatment and observation of the patient. Disease development and progression, which eventually led to a fatal outcome, were described in stages.&#x0D; The research and results were able to confirm the cause of death. Cavernous sinus thrombosis and other cerebral sinus thrombosis, as a complication of the main, timely undiagnosed, and untreated disease, is a significant problem even in modern multidisciplinary medical institutions and often causes deaths in clinical practice.

Analyzing the Most Relevant Predictors for Adult Coronary Heart Disease using Machine Learning

&#x0D; &#x0D; &#x0D; Coronary heart disease has been the number one illness to cause death in the world for decades. The healthcare indus-tries generates vast amount of clinical data, driven by medical records of patients, regulatory requirements, and results of medicalexaminations. In order to obtain the most relevant features for coronary heart disease, this study has conducted an experimental evaluation on data-driven diagnosis of coronary heart disease using classification algorithms. A statistical test (Chi-square) is usedto find the most valuable features and risk factors associated with coronary heart disease. The purposed of this univariate feature extraction algorithm is to determine the difference between the observed resuslts with expected results. Furthermore, CHD is predicted using several classification machine learning algorithms including Logistic Regression, Complement Naïve Bayes. andSupport Vector Machine (SVM). This study also evaluates ensemble machine learning algorithms, such as Random Forest and Extreme Gradient Boosting (XGBoost), Gradient Boost, to find the best performance of the classifications algorithms and select essential features from the dataset. Holdout and cross-validations methods are used to separated the dataset into two sets, called thetraining set and the testing set. The performance of proposed algorithm are assessed in terms of certain factors such as specificityand sensitivity. From this study, it is shown that Gradient boost model exhibits the best performance with 0.839 sensitivity.&#x0D; &#x0D; &#x0D;
