Effect of cell therapy with adipose-derived stem cells in the treatment of acute rupture of the Achilles tendon in humans.

The aim of this study was to evaluate the effect of adipose-derived stem cells (ADSCs) in the treatment of acute rupture of the Achilles tendon. It was a cross-sectional study involving 15 patients. Patients were randomly divided: group 1-rupture; group 2-suture; group 3-rupture + ADSCs. In the AOFAS score, the score was higher in group 3 with a significant difference. In the ATRS score, the score was higher in groups 2 and 3, also with a significant difference. As for the ultrasound score, there was a significant difference between the experimental groups in relation to this score, however, in the multiple comparisons test, comparing two groups at a time, it was possible to observe a significant difference of the experimental groups. It can be concluded that cell therapy in this condition may be a treatment option due to tissue regeneration and significant recovery of function.

Experimental introduction of specially - preparatory exercises in the training of young powerlifters 16-17 years old in the preparatory period

The article analyzes motor activity in various competitive powerlifting exercises, which made it possible to develop a training plan for a shock microcycle in the preparatory period for young athletes of the experimental group. The performance of any physical or strength exercise is associated with a certain mode of muscle work, and muscle strength increases significantly. In powerlifting, competitive exercises are: squats with a barbell on the shoulders, bench press, deadlift. The purpose of the work is to develop sets of exercises based on muscle groups that ensure the performance of competitive exercises in powerlifting by young powerlifters 16-17 years old. The maximum force that a person can show depends, on the one hand, on the biomechanical characteristics of the movement (the length of the shoulder levers, the possibility of its implementation with the help of the largest muscles, etc.), on the other hand, on the magnitude of the tension of individual muscle groups. The study involved young puerlifters 16-17 years old in the amount of 24 athletes. The control group carried out the training process according to the traditional methodology used in the Youth Sports School. Experimental according to the methodology developed by us, taking into account the use of complexes of exercises for each competitive exercise. In the course of the study, it was determined that, thanks to the knowledge of the anatomy of the muscles involved in a particular movement, it is possible to modify any exercise to obtain the desired result in the formation of the muscles of the shoulder girdle or muscles of the chest, back, arms, legs, buttocks or abdomen, as well as improve the technique of performing any exercise. Testing carried out at the end of the preparatory period indicates more significant results of the experimental groups in relation to the control group in bench press (t=3,23, p<0,01), squat with a barbell (t=2,93, p<0,05 ), and deadlift (t=2,20, p<0,05).

The effectiveness of a counseling program based on behavioral cognitive approach in reducing the severity of depression and improving the sense of self-esteem of a sample of adolescents in the northwestern Badia district

This study aimed to confirm the effectiveness of a group-counseling program based on behavioral cognitive approach in reducing the severity of depression and improving the sense of self-esteem among a sample of adolescents in the northwestern Badia district. The participants of the study consisted of thirty (30) student aging 12-14years. They are enrolled in the seventh and eighth grades in one of the schools affiliated with the Northwestern Badia Brigade in the Mafraq region. Among 130 students, they volunteered to participate in the pilot program after obtaining high marks on the Kovacs scale for child and adolescent depression and the self-esteem scale during the first semester of the academic year 2019/2020. The study participants were randomly divided into two groups: an experimental group and a control group. The participants in the experimental group (15 students) underwent a pilot program consisting of 10 sessions, while their counterparts in the control group (15 students) were not enrolled in any training. The results of the multivariance analysis showed that there are statistically significant differences on the scale of depression between the two study groups in favor of the experimental group in relation to the overall score of the scale. There is also a statistically significant difference on the scale of self-esteem between the two study groups and in favor of the experimental group, which indicates the efficiency of the indicative program in reducing the depression severity and improving self-esteem feelings. The study recommended the importance of applying the Counseling Programs that are based on the Behavioral Cognitive Approach in Reducing Depression symptoms and low Self-esteem among adolescent students.

ENHANCING THE PROBLEM-SOLVING AND CRITICAL THINKING SKILLS OF STUDENTS USING THE MATHEMATICAL INVESTIGATION APPROACH

The interest in understanding what is involved in doing mathematical investigations brought together several researchers and classroom teachers. In this paper, the proponent decided to set up a project to experiment with tasks involving students exploring and investigating mathematical ideas, concepts, and processes. The work includes producing, experimenting, and evaluating such tasks and studying the competencies needed for using them successfully in the mathematics classroom. This study aimed to describe the attitude and performance of the students when exposed to investigative tasks. It is also driven to compare the performance of the control and experimental groups in relation to the implementation of the intervention and to see whether their attitude towards math investigation matters in the students' problem-solving and critical thinking skills. 
 The findings showed that on the attitudes, the experimental group has a very favorable attitude toward the process of doing the investigation in spite of its complexity particularly in giving proof. The data obtained claimed that the control group did meet the expectations for both tests while the experimental post-test presented a very satisfactory performance indicating that their exposure to investigations taught them to explore and provide absolute mathematical reasoning. A significant difference was found in the performance of the two groups making the experimental group better than the control group as reaffirmed in the effect size of large. Further, students’ attitudes on the implementation of math investigation are described as a predictor of successful problem solving and improving the critical thinking skills of the students.

Psycho-Oncological Intervention Through Counseling in Patients With Differentiated Thyroid Cancer in Treatment With Radioiodine (COUNTHY, NCT05054634): A Non-randomized Controlled Study.

BackgroundDiagnosis and treatment of differentiated thyroid carcinomas (DTC) cause anxiety and depression. Additionally, these patients suffer hormonal alterations that are associated with psychological symptoms (e.g., changes in mood, emotional instability, and memory loss). This study aims to evaluate the effectiveness of a psycho-oncological intervention based on counseling to reduce anxiety and depression related to the treatment in patients with DTC.MethodsA non-randomized controlled study, with two groups [experimental group (EG), n = 37, and control group (CG), n = 38] and baseline and posttreatment measures, was designed. Patients in the EG received a psycho-oncological intervention based on counseling in addition to the standard treatment. The independent variable was the assigned group and the dependent one was the evolution of anxiety and depression, which were analyzed separately, and both were evaluated using the Hospital Anxiety and Depression Scale. Other relevant covariables related to the quality of life (QoL) were also analyzed using Short Form-36 Health Survey and Psychological General Wellbeing Index scales.ResultsThe difference of the posttreatment-baseline variation showed a statistically significant reduction in anxiety and depression in the EG in relation to the CG (p < 0.001). The mean of the Psychological General Wellbeing Index scales score increased significantly in the EG (p < 0.001) and decreased significantly in the CG (p < 0.001). All the baseline and the posttreatment scores of the variables evaluated showed a statistically significant improvement in the EG vs. the CG.ConclusionThis study demonstrates significant benefits of psycho-oncological intervention based on counseling in anxiety, depression, QoL, and wellbeing of the patient with differentiated thyroid carcinomas.

Investigation of Antibiotic Release from Bone Allograft in an Experiment on Rabbits

BACKGROUND: The treatment of chronic osteomyelitis, despite the use of new methods, is still an urgent problem. Local use of antibacterial drugs in combination with systemic antibiotic therapy has become popular in recent decades. Autologous bone grafts are considered ideal for bone defects filling. Different methods of allograft preparation may have differences in the rate and duration of antibiotic release. Moreover, it can affect the effectiveness of microbial agent eradication. The study analyzed the differences in the release of gentamicin from different types of allografts in dynamics and methods of preparation: «PerOssal» medium, whole bone allograft soaked in antibiotic, whole bone allograft, welded with an antibiotic, and perforated bone allograft soaked in an antibiotic solution. AIM: The objective of the study was to study the stability of antibiotic release and to determine the effectiveness of local transport systems. Evaluation of the difference in gentamicin release from different types of allografts in dynamics and methods of preparation had been realized: “PerOssal” medium, whole bone allograft soaked in antibiotic, whole bone allograft welded with an antibiotic, and perforated bone allograft, soaked in antibiotic solution. MATERIALS AND METHODS: The research was conducted between September 2020 and March 2021. The experiments were performed on 120 laboratory rabbits (weight – 3000–3500 g, age – 6–8 months), which were divided into four groups (30 animals in each group). Group 1 consisted of animals treated with “PerOssal.” The whole bone allograft soaked in an antibiotic was used in the treatment of animals of Group 2. The whole bone allograft, welded with an antibiotic, was used in the treatment of animals of Group 3. Perforated bone allograft soaked in an antibiotic was used in Group 4. Osteomyelitis of the proximal femur was formed in experimental animals. RESULTS AND DISCUSSION: Statistically insignificant decrease in the concentration of gentamicin was observed by the 7th day in all experimental groups. In rabbits whose bone defect was filled with a whole bone allograft welded with antibiotic and perforated bone allograft impregnated with an antibiotic (Groups 3 and 4), the most stable concentration of gentamicin was noted throughout the study period. Statistically significant differences were revealed between the experimental groups in relation to the dynamics of changes in the concentration of gentamicin in blood plasma. It was found that the group using the biodegradable material “PerOssal” on the 1st day showed a high concentration of the antibiotic in the blood plasma. However, by the 2nd day, a lower concentration of the antibiotic was recorded compared to all comparison groups of the bone allograft. CONCLUSIONS: The results of the analysis of the dynamics of gentamicin concentration may indicate significant differences between the methods of graft preparation, especially in the relationship with antibiotic release into the blood plasma. The most stable antibiotic concentration was registered in the groups of animals that underwent the filling of bone defect using a whole bone allograft welded with an antibiotic and a perforated bone allograft impregnated with antibiotic. A significant decrease of gentamicin concentration in the femur homogenate by the 7th day after transplantation was observed when using a whole bone allograft impregnated with an antibiotic. At the same time, a stable concentration of the antibiotic in the blood plasma was registered. The highest initial antibiotic concentration in the homogenate with a gradual decrease over 7 days was observed when using the antibiotic-impregnated biodegradable material “PerOssal.”

HEMATOLOGICAL PROFILE OF BROILER CHICKENS AFTER ACTION OF «ENTERONORMIN» IN COMPLEX WITH IODINE AND SELENIUM

The uncontrolled use of antibiotics, sulfanilamide preparations, coccidiostatics and numerous vaccinations leads to the emergence of antibiotic resistance, immunodeficiency and death of bird. In view of this, probiotics have been used to normalize the microflora of the intestine and the strengthening of immune and antioxidant functions. Microbial preparations from associations of non-pathogenic bacteria have a positive effect on performance and natural resistance of poultry, contribute to the restoration of a healthy microbiom and generally improve the efficiency of growing broilers. Therefore, in order to obtain biologically full and environmentally friendly poultry products, it is recommended to use synbiotic preparations from the first days of life.&#x0D; The article presents the results of a comprehensive study of indicators characterizing the hematological profile of broiler chickens during their cultivation under the action of the synbiotic preparation "Enteronormin" activated by aqueous solution of iodine and selenium. The drug contains living crops of useful microorganisms, the genus Lactobacillus spp., Enterococcus spp. and bacteria Bacillus subtilis, chitosan water-soluble, peptone microbiological, as a source of vitamins of the group B and indispensable amino acids. The results of conducted experimental studies have shown that the use of chicken broilers of the synbiotic drug "Enteronormin" in a complex with iodine and selenium caused a stimulus effect on the oxygen-transport function of blood. As evidenced by a greater number of erythrocytes and concentration of hemoglobin in the blood of chicken broilers of the experimental group in relation to control in all periods of research.

Bone mineral density of the rat tibia under modeling of glucocorticoid-induced osteoporosis and the influence of whole body vibration: experimental stud

The aim – investigate the effect of whole-body vibration with high-frequency on the mineral density of the tibia of rats treated with glucocorticoids.Material and methods. 54 adult male Wistar rats were randomized to three groups: control, experimental group I - rats treated with methylprednisolone and experimental group II - methylprednisolone with whole-body vibration. Rats of the two experimental groups received methylprednisolone at a dose of 3 mg/kg every other day for 24 weeks. Group II was subjected to a total vertical vibration (50 Hz, with a vibration acceleration of 0.3g) for 30 min per day, 5 days per week throughout the experiment. Mineral density was assessed by CT densitometry at 8-16-24 weeks of the study.Results. The most significant bone loss was observed in experimental group I at the 16th and 24th week of the experiment, which decreased by 18.6% and 20.8%, respectively, compared with the control group. In experimental group II, the bone density index did not statistically decrease at the 8th week of our study, but at the 16th week decreased by -16.3%; and on the 24th week by -23.5% according to the control group. The density of the cortical layer of bone tissue did not change statistically in the experimental groups in relation to the control group.Conclusions. Our study demonstrated that high-frequency mechanical oscillations could partially suppress the harmful effects of methylprednisolone on bone mineral density in rats. Because glucocorticoids are an important cause of secondary osteoporosis in humans, mechanical stimulation in the form of exercise and training can prevent bone loss and stimulate bone formation.

Video versus Traditional Teaching Strategy for Enhancing Intramuscular Injection Skills among College of Nursing Students in Kuwait: A Comparative Study

Purpose: The study aims to assess the performance and compare the effectiveness of intramuscular injection skills of nursing students utilizing two different teaching strategies –traditional (with the use of performance checklist only) versus video (together with the performance checklist).&#x0D; Methodology: A quasi-experimental research design was used. The sample was divided into two groups - control group, 28 female nursing students and experimental group, 27 male nursing students. Socio-demographic data sheet and an observational checklist were used to collect pertinent data.. Analysis was performed using descriptive statistics and analytical tests, such as the independent t-test between the experimental and control group, regarding the preparation and injection of medication. P value of &lt; 0.05 was considered to be significant. &#x0D; Findings: Most of the experimental and control group subjects are non-Kuwaitis. In medication preparation, the experimental group showed higher scores in the following steps: mixing solution; withdrawing prescribed amount of medication. The control group, on the other hand, scored higher in the following steps: removing needle cap, withdrawing into syringe amount of air equal to volume of medication to be withdrawn; carefully inserting needle into upright vial; and withdrawing prescribed amount of medication. In medication administration, the control group obtained higher scores in putting on clean gloves and applying gentle pressure at the site. The experimental group had higher score only in putting on clean gloves. A highly significant positive correlation was found between medication preparation and injection of medication and socio-demographic parameters of age and nationality (p= 0.008, p= 0.007) respectively. There is no statistically significant correlation detected between control and experimental group in relation to injection of the medication. &#x0D; Unique Contribution to Theory and Practice: The results of this study indicated that while traditional and video-assisted teaching are equally effective, there is no substitute for clinical demonstration.

BONE MINERAL DENSITY OF THE RATS TIBIA AFTER MODELING OF ARTIFICIAL MENOPAUSE AND INFLUENCE OF WHOLE BODY VIBRATION

Early deficiency of female sex hormones provokes bone loss in various parts of the skeleton, which further requires therapeutic correction. However, it is known that vibrational oscillations are anabolic for the trabecular layer of bone, which have been studied in both animal models and humans under physiological norms. It is likely that this anabolic reaction does not occur evenly throughout the skeleton, on the one hand, due to the cushioning properties of muscle tissue, ligaments, joints, and resonance, on the other.&#x0D; The aim of the study is to assess the condition and mineral density of the tibia under the condition of artificial menopause and the influence of non-physiological whole body vibration (WBV) with acceleration 0,3 g.&#x0D; Material and methods. The experiments were performed on 54 adult female Wistar rats. Rats were divided into three groups: control group (n=18) – SHAM surgery, experimental group I (n=18) - rats with ovariectomy, experimental group II (n=18) - rats after ovariectomy + WBV. Rats of were subjected to total vibration with acceleration of 0,3 g for 30 minutes 5 days a week for 24 weeks. At the 8th, 16th and 24th week of the experiment CT-densitometry of the tibia was performed.&#x0D; Results. The greatest loss of bone tissue was observed in experimental group I at the 24th week of the experiment, which decreased by 23.5% compared with the control group. At the 8th week of the study, the rate did not change statistically, and at the 16th - decreased to 8.1%. In experimental group II, bone density did not decrease statistically at the 8th and 16th week of our study, however, at the 24th week decreased by -16% to the control group, and compared with group I, increased by +11,2 % on the 24th day. The cortical layer of the tibial bone tissue did not change statistically in the experimental groups in relation to the control group. Factors that can affect the anabolic response in the tissues of the musculoskeletal system are the parameters of vibration, in particular the frequency and level of vibration acceleration. In our experimental study, we observed a decrease in bone mineral density in rats with ovariectomy and compared with ovariectomized rats subjected to vibration. We observed a positive correlation between whole body vibration and bone mass increase, which may be due to the effect of increased mechanical stress on the skeleton. We also demonstrated the negative effect of time after ovariectomy on bone density in experimental rats. The use of vibration maintained normal bone mineral density for a long time, and until the 16th week of the experiment, but at the 24th week, rate decreased significantly compared with the control group, but was higher than in group I. Analysis of CT scans showed high values of mineral density in experimental group II (ovariectomy + WBV) compared with experimental group I.&#x0D; Conclusions. The obtained results allow us to conclude that the WBV inhibits the accelerated remodeling after ovariectomy and prevents the rapid loss of bone tissue for a long time. To this end, mechanical vibrations should be used in the early menopause to maintain normal bone mineral mass. This therapy can be used alone and as an adjunct to osteoporosis medication. Therefore, early detection of osteopenia and timely appropriate treatment is important, which, in addition to antiresorptive drug treatment, should include lifestyle changes and exercise.

INTEGRACIÓN Y EVALUACIÓN DE UNA PROPUESTA PARA LA ENSEÑANZA DEL CONOCIMIENTO ESTRATÉGICO EN CAD

Computer-aided design competency is critical for an engineering graduate starting in the world of work. Therefore, the development of this competency must be in line with professional requirements and consider the design constraints. For example, in the case of modeling, a geometrically correct model may not be sufficient if it is unable to withstand the modifications required by design changes. Therefore, we consider that training must be based on the development of this knowledge, known as strategic knowledge, and encourage its acquisition. This article describes a CAD training proposal focused on the development of strategic knowledge. Starting from the contributions of researchers, the modeling process is broken down so that it can be reproduced in the different scenarios that may be presented at the time of modeling. In order to facilitate the acquisition of this knowledge, an active learning framework has been established and specific didactic strategies have been developed for this purpose. Finally, the results of an empirical test are presented after the implementation of this proposal in which the results show a notable improvement in the experimental group in relation to the control group. Keywords: CAD modeling, teaching-learning, strategic knowledge

ИСПОЛЬЗОВАНИЕ ЗАДЕРЖКИ ДЫХАНИЯ В СПОРТИВНОЙ ТРЕНИРОВКЕ ДЕТЕЙ 10–12 ЛЕТ КАК СПОСОБ ПОВЫШЕНИЯ ИХ ФУНКЦИОНАЛЬНОЙ ВЫНОСЛИВОСТИ

Statement of the problem. The article describes an alternative and affordable method of hypoxic training through holding the breath on inhalation and exhalation, as a tool for developing endurance. The relevance of the topic is in the absence of a method that develops endurance and hypoxic characteristics with a sparing effect on heart rate (HR) and availability in use. Research methodology (materials and methods). Using hypoxic tests of Stange and Genchi (holding the breath on the inhale and exhale by the stopwatch), as markers that determine the development of endurance, we arranged the experiment. We divided 24 young men of volleyball players aged 10–12 into two groups, experimental and control, 12 people in each group with a uniform level of sports fitness. The arithmetic mean of indices in the introductory Stange samples in the control group and in the Genchi samples showed 1 minute 8 seconds and 31 seconds, respectively. In the experimental group, there were 48 seconds in the Barbell samples and 25 seconds in the Genchi samples, confirming the uniformity of training in the development of endurance. The experiment lasted three months, during which time the experimental group underwent breathing exercises on inhalation and exhalation, regulated by the time of 20 and 7 seconds, maximum in the corridor of execution, and the control group trained in the normal mode. At the end of the experiment, samples were taken, similar to the introductory ones. The average result of the breath holding time in the control group changed by 4 seconds in the Genchi and Stange samples, in relation to their own results, and the results of the experimental group in relation to their own results increased by 1 minute 13 seconds in the Stange sample and by 23 seconds in the Genchi sample. The values of the samples are detailed in Table. Research results. As a result of the study, the experimental group exceeded the control group in the samples with breath-holding during inhalation (Stange) by 47 seconds and breath-holding during exhalation (Genchi) by 31 seconds. This practically confirms the significance of hypoxic training with regulated breath holding to develop endurance. Conclusion. The experiment proves the effectiveness of alternative hypoxic training with regulated breath holding during inhalation and exhalation and contributes to the further study of the tool, which is available for material and technical use.

Efficacy and Safety of Socheongryong-Tang Among Atopic Dermatitis Patients With Respiratory Disorders: A Double-Blinded, Randomized, Placebo-Controlled Clinical Trial.

Atopic dermatitis is a chronic inflammatory skin disease that affects the growth and development of children. The prevalence of atopic dermatitis has been continually increasing, and this has also been accompanied by rising socioeconomic costs. Interest has been growing in alternative medicine as a means of alleviating the burden of atopic dermatitis. This was a single-center, double-blinded, randomized, placebo-controlled investigator-led clinical trial including 60 atopic dermatitis patients. The participants were classified into an experimental group (30 persons) and a control group (30 persons), who were administered, respectively, socheongryong-tang or a placebo for 4 weeks. After 4 weeks of treatment, the participants visited the trial center again and assess their efficacy and safety. The researchers performed statistical comparisons of the changes in the SCORAD Index, amount and frequency of ointment use, and height and weight to assess the efficacy. To assess the safety, diagnostic tests and vital sign checks were performed at each visit, and the presence or absence of adverse events was observed. As a result, the frequency and the amount of steroid ointment application in both groups increased, but the experimental group showed less tendency (p = 0.081). Results of analyzing the children in the experimental group in relation to growth showed a significantly greater height growth than the control group (p < 0.05). In addition, all study participants did not show any remarkable abnormal signs in the safety evaluation. In conclusion, compared to the control group, the experimental group, who took socheongryong-tang showed a tendency to be less dependent on steroid ointment and statistically significant increase in height.

Efeito do treino específico e de curta duração na aquisição e retenção do alcance manual em lactentes prematuros e baixo peso ao nascimento

Este é um estudo de caráter descritivo, longitudinal, com amostra por conveniência de natureza aplicada, desenvolvido de fevereiro a dezembro de 2018, com o objetivo de verificar se o treino específico, condição de prática variada seriada, de curta duração, influencia o comportamento de alcance manual e a retenção da habilidade em lactentes pré-termo com baixo peso ao nascimento. Participaram seis lactentes de ambos os sexos, aleatoriamente divididos em: grupo experimental que recebeu treino específico, e grupo controle que recebeu apenas interação social. Foram analisados 180 alcances de ambos os grupos. Embora sem diferença estatisticamente significativa, mas com relevância clínica, os resultados demonstraram que o treino específico promoveu melhora na frequência total do alcance (d=0,88, 95% IC), e, nos ajustes distais do alcance (mão oblíqua e semiaberta), no grupo experimental em relação ao grupo controle. Nos parâmetros cinemáticos do alcance, os resultados mostraram um alcance mais organizado, indicando que algo foi aprendido e/ou mudado no período imediato ao treino, contudo, não foi verificada a retenção da aprendizagem. Assim, acredita-se ser necessário um treino mais prolongado para se obter a retenção da aprendizagem.

Espirulina un suplemento alimenticio como posible alternativa en el control de peso. Un estudio con ratas Wistar

Recently spirulina algae have been used for weight reduction. It is known that at least 36 g of this algae provide all the essential amino acids, among other different compounds such as fiber and flavonoids with the possibility of treating obesity or overweight, The objective was to determine if the administration of spirulina helps reduce body weight in Wistar rats as well as determining possible effects on the metabolism of different general bio-chemical markers such as a lipid profile, urea and creatinine. A double-blind experimental study was applied using 10 Wistar rats, four rats called experimental rats, 5.8 mg of spirulina diluted in 1 mL of water, by orogas-tric tube for eight weeks, were administered to the control group (6 rats same species and initial weight) He was given only 1 mL of water. The weight of the experimental rats versus the controls had no significant changes. Regarding the biochemical markers, only a significant increase in the values of urea, total cholesterol, and tri-glycerides of the experimental group in relation to the control was found. The findings suggest the intake of spirulina for weight control and in possible states of malnutrition.
