Background. The teacher needs to analyse and promptly make changes in each student’s dosage of physical activity in the class. At the same time, students within the group differ from each other in gender, age, physical fitness and health level. Such differences make it difficult to clearly discern the individual characteristics of every student and thus to help them develop their physical data in the best way, choose a proper motor regime to improve their health. The aim of the work is to calculate and analyse the physical health index for 1st-year students of the 2023-2024 academic year at the Russian New University in scores in order to control their physical condition in the discipline “Physical Culture”. Materials and methods. The survey used the methods, tests and computer programmes developed by the Association “People’s Sports Park”. The Association “People’s Sports Park” has a patent of the Russian Federation No. 2147208 for the “Method of assessing physical health reserves and working capacity of the population” and the ownership right to the computer programme processing and evaluating testing results for different categories of the population. Materials of the research: data from 15 tests for the following human body systems: cardiovascular, respiratory, muscular, nervous. The tests include measurements made both in the state of relative dormancy and in dynamics. The main method of working with the obtained data was their statistical processing and analysis of its results. Results. The article reflects the findings of the study of the first-year students’ heart rhythm obtained with the use of technical means and recorded in real time. The calculation of the physical health index (PHI) of the first-year students made in the 2023-2024 academic year showed the following distribution: • 34% of the students scored between 3 and 3.9 out of 6 points maximum and have a satisfactory level of health and performance ability; • 41% of the first-year students have an unsatisfactory physical condition, which corresponds to 2.0-2.9 points out of 6 maximum; • 25% of the first-year students have good and excellent health levels, which corresponds to 4-6 points; • 75% of the first-year students have a quality of health that requires perfection and maximum control by specialists.

Introduction. The relevance of the article is determined by the importance of assessing the determinants of fertility to determine the possible prospects for its change and the correct justification of the directions and measures of demographic policy aimed at increasing it. The aim of the study is to identify the determinants of fertility decline in the Republic of Tatarstan in 2020‒2022 in comparison with the pre-pandemic period and to predict their impact. Materials and Methods. The authors have calculated and analyzed the dynamics of age-specific fertility rates in the Republic of Tatarstan. The influence of the structural factor and the factor of birth intensity, as well as the indirect factor ‒ age-specific marriage rates ‒ was estimated. Using the method of age movement, the dynamics of fertility and the impact of these factors on it up to 2042 were forecasted. Results. The decrease in the total fertility rate in the Republic of Tatarstan in 2020‒2022 was due to changes in the sex and age structure of the population. The excess of the total fertility rate of the region over the indicators of the Volga Federal District and the Russian Federation is due to higher total coefficients for first and second births. The difference between the average number of first births for real generations and for calendar years is determined by temporal shifts associated with postponement of first births due to late entry into first marriage and registered marriages. Discussion and Conclusion. It is predicted that the number of young people will decrease until 2028 and the number of births until 2031. The negative impact of the factor of the gender and age structure of the population will last until 2030, in the 2030s the structural factor will contribute to an increase in the overall fertility rate. The research results presented in the article can be used to determine hypotheses regarding fertility prospects when developing forecasts for demographic and socio-economic development. Correct assessment of the determinants of fertility provides grounds for the development of effective measures of demographic policy with regard to fertility.

The aim of the study was to evaluate the data of phylogenetically analyzed nucleotide sequences from the K. pneumoniae strain uge genes carried out in the perinatal center. Materials and methods. Fifty-six sequences of the K. pneumoniae uge gene were analyzed. The uge gene was detected by real-time PCR using DT light amplifier (Russia). Results. The rate of K. pneumoniae strains among patients of obstetric and gynecological departments in 2020–2023 averaged 1.4%. In pediatric hospitals, the isolation of K. pneumoniae strains comprised 12–14% in 2020, 2021 and 2023. In 2022, a fourfold decrease in detected K. pneumoniae strains was recorded. Phylogenetic analysis showed that the nucleotide sequences were significantly grouped into 14 clusters. The K. pneumoniae virulence factor uge gene is found in 64.3% cases. The nucleotide sequences allowed to detect heterogeneous K. pneumoniae strain population isolated from patients at the perinatal center from 2019 to 2023 analyzed by the phylogenetic method. There are clusters that combine K. pneumoniae genovariants isolated in 2019 and not replenished with new isolates, which confirms the effectiveness of ongoing anti-epidemic measures, enhanced during COVID-19 spread, excluding the transmission of an infectious agent from a source to a susceptible organism in nosocomial environment. P249Q, N279L amino acid substitutions within the uge gene were determined, which distinguish hypervirulent strains from those with a lower degree of pathogenicity. Out of five mother-child pairs, in four — nucleotide sequences of K. pneumoniae strain uge gene were genetically closer to each other than to other strains isolated from patients of the Medical Departments suggesting about a high degree of their relationship, highly likely indicating that the source of the strain for the child was the paired mother, and not the patients of the departments or the staff of the institution. In one mother-child pair, K. pneumoniae strains belonged to different clusters. The isolate obtained on 09/06/2021 from neonatal faeces (age: 7 days old) was grouped with strains isolated on 12/12/2020 from a patient in the maternity ward and in Laos in 2013 (CP035196). K. pneumoniae isolated on 06/04/2021 from the urine of a woman, was significantly grouped with strains included in cluster 13. Conclusion. An opportunity for improving local microbiological monitoring by sequencing and phylogenetic analysis of K. pneumoniae uge gene has been demonstrated. Assessment of changes in the intraspecies population pattern of HCAI pathogens is necessary for a timely and reasonable response to the deterioration of the epidemiological situation.

Aim. To evaluate the endometrial microbiota in patients with uterine scar defect after cesarean section. Materials and methods. The study included 80 women of reproductive age. The main group included 50 patients with a uterus scar defect due to cesarean section; the comparison group included 30 women with a competent uterus scar due to cesarean section. Patients underwent a Pipelle endometrial biopsy on days 2022 of the menstrual cycle using a double-lumen catheter that excludes sample contamination with vaginal and cervical microflora. A molecular genetic study of the endometrium was performed by real-time polymerase chain reaction using the Femoflor 16 reagent kit (DNA-Technology Moscow). The DNA content in the specimen was measured using software and expressed in genome equivalent (GE) proportional to the number of microorganisms. The statistical data were processed using the Exсel software package and SPSS Statistics 22.0. Results. The study showed the following statistically significant differences: lower count of Lactobacillus spp. 2.600 (1.4303.600) GE/mL vs 3.550 (2.8004.700) GE/mL in patients of the comparison group (p=0.02); higher count of Streptococcus and Staphylococcus spp. 3.270 (3.0003.700) GE/mL and 3.450 (3.2003.600) GE/mL vs 1.030 (0.7601.700) GE/mL and 0.560 (0.1201.200) GE/mL in the comparison group, respectively (p0.00001); higher count of Enterobacteriaceae 2.700 (1.7003.300) GE/mL vs 0.950 (0.6601.120) GE/mL in the comparison group (p0.00001); higher count of Gardnerella/Prevotellabivia/Porphyromonas spp. 2.310 (0.9303.480) GE/mL vs 1.000 (0.0001.860) GE/mL (p=0.003); higher count of Peptostreptococcus spp. 0.195 (0.0001.560) GE/mL vs 0.000 (0.000-0.000) GE/mL (p=0.032); Eubacterium spp. 1.355 (0.1002.460) GE/mL vs 0.000 (0.0001.560) GE/mL (p=0.040). Conclusion. Endometrial dysbiosis in patients with a uterus scar defect after cesarean section due to the possible effects of microorganisms can be considered one of the leading causes of the formation of a uterus scar defect in the postoperative period.

Introduction. The family forms the habitus of the child's health-preserving behavior: the presence or absence of bad habits, involvement in sports, food preferences, and the attitude to disease prevention. The article, based on the conducted research, identifies the dependence of various parameters of the health of school-age children on the socio-biological well-being of the family, its lifestyle, life support conditions that contribute to the implementation of family health-preserving practices. Materials and Methods. The research materials used were the data from a survey conducted in 2019 by the Center for Family and Demography Center of Tatarstan Academy of Sciences among parents of students of lyceums, grammar schools, and general education schools, including those with in-depth study of specific subjects (city of Kazan, Arsk and Chistopol municipal districts of the Republic of Tatarstan). The total population of parents of students was 433,706 people, the selection was 325 people. The value, social activity, and generation approaches within the sociological discourse on health issues are aimed at identifying the social determinants of various parameters of adolescent health and their health preservation habitus. Results. The study has identified a number of factors that determine the lifestyle of modern schoolchildren and have a negative impact on their health in the context of significant academic loads, intensification of the educational process, and involvement in intense extra-curricular activities: non-compliance with age regulations of the daily routine; low motor activity; unsatisfactory organization and deterioration of the quality of nutrition in the family; habitus of parents’ behavior, not focused on health preservation. Discussion and Conclusion. The conducted research provides scientific substantiation of and emphasizes the need for measures aimed at increasing physical activity and healthy nutrition of both younger and older schoolchildren in the context of the demographic crisis. Practical application of the conclusions drawn in this study involves formulation of proposals for improving the effectiveness of managerial decisions taken by ministries and departments of the Republic of Tatarstan.

Abstract Background Patients’ comfort level during the injection procedure affects the quality of care. However, the literature does not provide a valid, reliable, and specific measurement tool to measure this level. Objective The present study aimed to develop a valid and reliable measurement tool to determine patients’ comfort levels during the injection procedure. Method The study was designed methodologically. The study data were collected at two Hospitals. The sample consisted of 102 patients in the pilot application stage and 186 patients in the main application stage. The study’s data collection tools were the “Personal Information Form,” “VAS for Comfort,” and the “Comfort Scale for Injection” draft. The obtained data were used for validity and reliability analyses. Validity analyses involved content validity, Exploratory Factor Analysis (EFA), Confirmatory Factor Analysis (CFA), and criterion validity. Reliability was assessed using Cronbach's Alpha and split-half tests. Statistical analyses were performed with SPSS 22 and AMOS. EFA used the KMO test and Bartlett’s Test (KMO = 0.878; p

ABSTRACT Objective: This study aimed to examine the experiences of nursing students learning psychomotor skills during the COVID-19 pandemic, the problems they experienced in this process, and their feelings and needs. Methods: This was a qualitative phenomenological study. The research was analyzed descriptively and thematically. The research was conducted in Erzurum in January 2022. The population of the study consisted of 2nd-year students studying at the Atatürk University Faculty of Nursing in the fall semester of the 2021–2022 academic year. The sample consisted of four second-year undergraduate nursing students selected by the criterion sampling method. The research data were collected with an ‘Introductory Information Form’ and a ‘Semistructured Questionnaire’. The content analysis method was used to evaluate the qualitative data. Results: Four themes and three subthemes were identified as a result of the analysis of the data obtained from the interviews with the students. The main themes are inefficiency, expectations from the instructor, emotions, and active learning. It was determined that inefficiency was categorized under the subthemes of “Problems experienced in online education and the limitation of online education in terms of learning psychomotor skills” and “Reasons for inefficiency”. It was determined that there were no subthemes in the themes of expectations from the instructor and emotions. Active learning was found to be under the subtheme of “Getting more efficiency from homework rather than what the instructors teach”. Conclusions: The online education process was inadequate for learning the psychomotor skills of nursing students.

Background: It is unknown if health-care literacy and social media use of the students affect vaccine preferences during the COVID-19 pandemic. Objectives: The aim of the present research was to detect whether health-care literacy and social media use of the students affect vaccine preferences during the COVID-19 pandemic. Materials and Methods: The universe of the sample consisted of the students of a university in Mus Alparslan University. The sample of the research included students whose last digit of the school number is an odd number. Four hundred and twenty students participated into the study. The data of the study were collected through the “Sociodemographic Characteristics Questionnaire,” “Health Literacy Scale (HLS),” and “Social Media Usage Scale (SMUS).” Results: The total score average of the students on the “HLS” was 42.74 ± 13.85 and the “SMUS” was 21.30 ± 7.38. It was determined that those who have preferred the “Sinovac” vaccine had higher score averages on the “Information Understanding Subdimension” and “HLS” than those who have preferred the Türkovac vaccine. Furthermore, it was determined that the score average of “Continuity Subdimension,” “Competency Subdimension” and “Social Media Use Scale” were higher, and these differences were statistically significant. Conclusion: It was detected that the health literacy (HL) levels of the students were lower and they do not use social media competently. On the other hand, it was determined that social media use and HL affect the vaccine preferences.

Background: Optimizing hamstring exercises is crucial for injury prevention and performance. This study explored the effects of blood flow restriction (BFR) during Nordic hamstring exercises (NHE) on hamstring muscle activation and vascular function., Methods: A randomized, single-blind study included 14 healthy, physically active males (mean age: 27.5 years). Each participant's lower extremities were randomly assigned to BFR or control groups. In the BFR group, blood flow was restricted to 60% of arterial occlusion pressure. Participants performed three sets of five NHE repetitions. Endothelial function was assessed by flow-mediated dilation (FMD) via Doppler ultrasound before and after exercise. Surface electromyography (EMG) recorded neuromuscular activation of the semitendinosus (ST) and biceps femoris (BF) muscles during exercises., Results: FMD values showed no significant differences between BFR and control groups (F(1,13) = 0.156, p = 0.7, partial η² = 0.012). Neuromuscular activations of ST and BF muscles decreased across sets in both groups but did not differ significantly between groups (ST: F(2,26) = 1.172, p = 0.448, partial η² = 0.09; BF: F(2,26) = 1.442, p = 0.527, partial η² = 0.1)., Conclusions: BFR did not produce acute additional effects on muscle activation or endothelial function compared to standard NHE. This suggests that incorporating BFR in NHE may not enhance immediate neuromuscular or vascular responses. Further research is needed to evaluate its long-term benefits., (© 2025 Scandinavian Society of Clinical Physiology and Nuclear Medicine.)

Background: Rheumatoid arthritis (RA) is a systemic and autoimmune disease that affects many tissues and organs in the body, especially the synovial joint and periarticular structures. One of the most affected joints is the hand joints, and there is also involvement in the wrist joint., Objectives: The purpose of this study was to assess the sensory and motor functions of the wrist with a gold standard method and to determine the relationship between the motor and sensory functions of the wrist and wrist-related pain/disability level and hand grip strength in patients with RA., Method: Flexor and extensor muscle strength and joint position sense of the wrist were evaluated using isokinetic dynamometer, hand grip strength was measured using dynamometer, and wrist related pain and disability was assessed by Patient Rated Wrist Evaluation (PRWE) questionnaire., Results: Thirty-one patients with RA and 31 healthy controls were included in the study. Control group had better results regarding wrist flexor and extensor muscle strength and wrist joint position sense than RA patients for both hands/wrists. A positive and strong correlation and a negative and weak correlation were found between muscle strength and joint position sense of the wrist and hand grip strength, respectively., Conclusions: Compared to healthy subjects, RA patients showed wrist-related sensorimotor deficits. Therefore, evaluation of the wrist should not be ignored in the examination of patients with RA. In addition, when planning the treatment program of the patients, not only hand exercises but also exercises involving the wrist should be taken into consideration., Competing Interests: Declaration of competing interest Nurten Gizem Tore, Ali Zorlular, Derya Yildirim, Nevin Atalay Guzel and Deran Oskay declare that they have no conflict of interest., (Copyright © 2024 Elsevier Ltd.

Objective: To determine the myotoxicity of bupivacaine on muscles after suprainguinal fascia iliaca block for postoperative analgesia in total knee arthroplasty (TKA) patients through changes in serum creatine phosphokinase (CPK) levels during the perioperative period., Study Design: Observational study. Place and Duration of the Study: Postoperative Recovery Room department of Anaesthesiology and Reanimation, Samsun University, Samsun, Training and Research Hospital, Samsun, Turkiye, between December 2022 and February 2023., Methodology: Patients undergoing for the procedure of TKA surgery were recruited. (40 controls and 42 SIFIB groups). Serum CPK levels were evaluated preoperatively, at postoperative 6th hour and 24th hour., Results:  From total 82 patients, 42 of them who received SIFIB as a component of multimodal analgesia had serum CPK levels comparable to those in the control group at all time points (p>0.05). While the increase in CPK level at 6th hour relative to baseline was significant in both groups (p<0.05), only the block group demonstrated a statistically significant difference between the 6th and 24th hours (p<0.05)., Conclusion: SIFIB administration did not result in severe bupivacaine-induced myotoxicity in comparison to the control group. SIFIB administration is a safe option when used as part of multimodal analgesia in TKA., Key Words:  Bupivacaine, Creatine phosphokinase, Myotoxicity, Regional anaesthesia.

This study explored the effects of the germination of red and white sorghum grains ( Sorghum bicolor [Moench (L.)]) for up to seven days on various properties of the grain. Germination enriched sorghum's nutritional and sensory qualities while mitigating existing anti-nutritional factors. The study employed Fourier-transformed infrared spectroscopy (FT-IR) and scanning electron microscopy techniques to support its findings. Germination increased protein and lipid content but decreased starch content. White sorghum grains showed elevated calcium and magnesium but decreased iron, potassium, and zinc. Red sorghum grains showed a consistent decrease in mineral content during germination. Germination also increased fiber and lignin values in both sorghum varieties. The results of the FT-IR analysis demonstrate that germination induced significant changes in the molecular structure of white sorghum samples after 24 h, whereas this transformation was observed in red sorghum samples at four days. Total phenolic content (TPC) in red sorghum ranged from 136.64 ± 3.76 mg GAE/100 g to 379.5 ± 6.92 mg GAE/100 g. After 72 h of germination, the germinated seeds showed a threefold increase in TPC when compared to ungerminated seeds. Similarly, the TPC of white sorghum significantly increased ( p < 0.05) from 52.84 ± 3.31 mg GAE/100 g to 151.76 mg GAE/100 g. Overall, during the 7-day germination period, all parameters showed an increase, and the germination process positively impacted the functional properties that contributed to the health benefits of white and red sorghum samples.

Colorants are widely employed in the food industry as an essential ingredient in many products since color is one of the most valued attributes by consumers. Furthermore, the utilization of colorants is currently being extended to the food packaging technologies. The objective of this review was to compile recent information about the main families of natural coloring compounds, and to describe their real implications in food coloring. In addition, their technological use in different food systems (namely, bakery products, beverages, meat and meat products, and dairy products) and their utilization in intelligent packaging to monitor the freshness of foodstuffs with the aim of extending food shelf life and improving food properties was discussed. The potential of using natural colorant in different food to improve their color has been demonstrated, although color stability is still a challenging task. More interestingly, the application of intelligent colorimetric indicators to exhibit color changes with variations in pH can enable real-time monitoring of food quality., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2022 Elsevier Ltd.
