Published: July 2021

Background. There is not enough research on the topic of arthroscopic treatment of medial epicondylitis. Topographic studies are needed to justify surgical approaches with minimal trauma to the medial collateral ligament and ulnar nerve. The aim of the study was to optimize the arthroscopic treatment of medial epicondylitis and evaluate its clinical effectiveness based on the results of the topographic and anatomical study. Materials and Methods. The material for the topographic and anatomical study was 12 «fresh» anatomical preparations of the human elbow joint, of which 6 were taken from female cadavers, and 6 — from men. The features of the structure and topography of the elbow medial collateral ligament were studied, and the safety and effectiveness of arthroscopic approaches to the elbow for the flexor carpi radialis release were determined. A prospective cohort comparative study was performed, which included 70 patients. Two comparative groups were formed. In the group I (35 patients) surgical treatment was carried out by the open method. The group II included 35 patients who underwent minimally invasive surgical treatment using arthroscopic technique. The results were evaluated by Mayo Elbow Perfomance Score (MEPS) and VAS before surgery and 1, 6, and 9 weeks after. Results. Functional results in 9 weeks: group I — 81.77 (95% CI 81.13; 82.41); group II — 92.66 (95% CI 91.61–93.70) points. The average score for VAS in the same period: group I — 34.30 (31.89–36.68) points; group II — 1.5 (0.46–2.45) points. Conclusion. The safe zone is located above the midline of the humeroulnaris joint by 2 (1.0–3.2) mm. The risk of the medial ulnar collateral ligament anterior bundle injury is minimal in this area. Treatment of patients with the medial epicondylitis according to the developed arthroscopic technique can significantly improve the patients functional state and quality of life.

Background.Osteoporosis is the fourth most common disease after cardiovascular diseases, cancer, and diabetes. All these diseases have common pathogenetic mechanisms associated with impaired cholesterol metabolism. In recent decades, the use of the key enzyme of cholesterol synthesis inhibitors — statins, which can stimulate osteogenesis, has become widespread. However, statins affect the production of the vitamin D active form by reducing the production of testosterone and thus reducing the activity of 1α-hydroxylase. The combined use of statins and α-calcidol (α-C) for the osteoporosis prevention seems promising. The aim of the study was to evaluate the effect of long-term atorvastatin (ATV) and α-C administration on morphometric growth parameters and bone vascularization in the experiment.Materials and Methods. The experiment was conducted for three months on 120 laboratory male rats, which were injected daily intragastrically with ATV and α-C. After 90 days of the experiment, the animals were decapitated under ether anesthesia. For the study, the right femur and jawbone were taken from the animals. The rat bone sections were impregnated with silver, decalcified, and the histosections were stained according to van Gieson. The distribution of the studied features was evaluated according to the Shapiro-Wilk test. The differences were considered statistically significant at p0.05.Results.It was found that ATV, both separately and together with α-C, increased the size of the newly formed bone in the endoostal and periosteal zones of the femur by 64.8; 40.4 and 15.8; 29.1%, respectively. The combined use of ATV and α-C had a positive effect on the growth of blood vessels in the femur (+23.4%). ATV increased the size of the newly formed bone from the periodontal and vestibular surfaces of the lower jaw by 18.3 and 29.5%, respectively. α-C potentiated the effect of ATV on the size of the newly formed bone tissue in the periodontal and vestibular growth zones of the mandibular bone by 10.1 and 15.0%, respectively. As for the number of vessels in the jawbone tissue, thanks to ATV, it increased by 17.2%, α-C had no effect.Conclusion. ATV increases the thickness of the newly formed bone layer in the growth areas of the femur and jawbone and increases the number of vessels in the jawbone. α-calcidol increases the number of vessels in the bone tissue of the femur and potentiates the effect of ATV on the jawbone growth zones. The combined use of ATV and α-C shows that they positively complement each other.
The Optimal Surgical Needle for Tendon Suture: Cutting Edge or Reverse Cutting Edge?
Authors: Zolotov A. S. , Isokov S. Kh. , Isokova A. Kh. 
Published: July 2021

Background. Achieving a durable connection between the lacerated tendon ends is difficult. The outcome of treatment depends on many factors. Several authors consider the properties of the surgical needle used for suturing the tendon to be important. The aim of the study— to compare the strength of the tendon suture applied with the conventional cutting edge and reverse cutting edge surgical needles in the experiment.Materials and Methods.We used porcine tendons for the experiment. The tendon fragments were divided into 2 groups of 20 tendons each. On all 40 tendons, the same type of “injury” of the tendon was simulated — using a scalpel. In the first group, the interrupted suture of the tendon was applied with a cutting edge surgical needle, in the second group — reverse cutting edge. Laboratory tests of the tendon sutures strength were performed on the improvised stand.Results.In the first (suture made with a cutting needle edge), diastasis of 2 mm was determined at an average load of 1219.5 g (m = ±76.56, where «m» is the representativeness error). Complete suture failure occurred at an average load of 1770.8 g (m = ±100.02). In this group, the thread rupture was not recorded. In the second group (a suture made with a reverse cutting edge needle), diastasis occurs with an average load of 1754.75 g (m = ±77.32). Complete suture failure occurred at an average load of 2571.25 (at m= ± 103.78). In three cases, the thread ruptured. In the second group (reverse cutting edge needle), the tendon suture strength was statistically significantly higher than in the first group. Conclusion. The tendon suture strength depends on the surgical needle properties. In tendons reconstruction the reverse cutting edge needle use is more preferable compared to the conventional cutting edge needle use.

Background. Knowledge about the pathological processes in the tissues of the limb is necessary for the targeted optimization of their course, the expectation of certain treatment results. The aim of the study was to determine the ratio of different severity cases and the correlation between individual clinical, laboratory and morphometric indicators of the tissues state in patients with trophic disorders in the extremity.Materials and Methods.The material was fragments of the lower leg tissues (bones, soft tissues, skin) of 38 patients with chronic post-traumatic osteomyelitis. Gradation morphometric indicators reflecting the tissues state in the lesion focuses were used. Frequency analysis of semiquantitative indicators and correlation analysis of the relationships between clinical, laboratory and morphometric indicators with the evaluation of the association coefficient were carried out. Results.Trophic disorders in the limb tissues (bones, soft tissues, muscles, skin), observed in patients with lower leg bones post-traumatic osteomyelitis, do not represent a group of well-defined pathological processes. They form a complex of dyscirculatory, ischemic, necrotic, dystrophic, atrophic, inflammatory, reparative and regenerative changes, which are combined in tissues in different proportions. This involves the use of a number of quantitative and semi-quantitative, gradation indicators: clinical, laboratory, and pathomorphological. Pathomorphological changes in the lesions in patients with chronic posttraumatic osteomyelitis of the lower leg bones with clinical signs of trophic disorders do not differ qualitatively from the changes usually detected in chronic post-traumatic osteomyelitis. In the bones, the most frequent are destructive focuses with a predominance of exudative and productive inflammation of high activity, sequestration and osteonecrosis. In paraossal soft tissues, more common are focuses, in which mature fibrous tissue and productive inflammation of low activity predominate. In the skin near the chronic post-traumatic osteomyelitis focuses, there is dermis fibrosis and productive inflammation of low activity.Conclusion. A number of correlations between clinical and laboratory parameters, on the one hand, and morphological parameters, on the other, have been established. The closest and most stable connections for different sites are the following indicators: blood leukocytes (negative dependence for affected bone, soft tissue and skin tissues), ESR (positive dependence for soft tissues), C-reactive protein (positive dependence for soft tissues and skin), agglutination with a polyvalent strain of Staphylococcus aureus (negative dependence for affected bones and skin).
Barriers to and Facilitators for Using Nutrition Apps: Systematic Review and Conceptual Framework
Authors: König Laura Maria , Attig Christiane , Franke Thomas , Renner Britta 
Published: July 2021

Background
Nutrition apps are effective in changing eating behavior and diet-related health risk factors. However, while they may curb growing overweight and obesity rates, widespread adoption is yet to be achieved. Hence, profound knowledge regarding factors motivating and hindering (long-term) nutrition app use is crucial for developing design guidelines aimed at supporting uptake and prolonged use of nutrition apps.

Objective
In this systematic review, we synthesized the literature on barriers to and facilitators for nutrition app use across disciplines including empirical qualitative and quantitative studies with current users, ex-users, and nonusers of nutrition apps.

Methods
A systematic literature search including 6 databases (PubMed, Web of Science, PsychINFO, PSYNDEX, PsycArticles, and SPORTDiscus) as well as backward and forward citation search was conducted. Search strategy, inclusion and exclusion criteria, and the planned data extraction process were preregistered. All empirical qualitative and quantitative studies published in German or English were eligible for inclusion if they examined adolescents (aged 13-18) or adults who were either current users, ex-users, and nonusers of nutrition apps. Based on qualitative content analysis, extracted individual barriers and facilitators were grouped into categories.

Results
A total of 28 publications were identified as eligible. A framework with a 3-level hierarchy was designed which grouped 328 individual barriers and facilitators into 23 subcategories, 12 categories, and 4 clusters that focus on either the individual user (goal setting and goal striving, motivation, routines, lack of awareness of knowledge), different aspects of the app and the smartphone (features, usability of the app or food database, technical issues, data security, accuracy/trustworthiness, costs), positive and negative outcomes of nutrition app use, or interactions between the user and their social environment.

Conclusions
The resulting conceptual framework underlines a pronounced diversity of reasons for (not) using nutrition apps, indicating that there is no “one-size-fits-all” approach for uptake and prolonged use of nutrition apps. Hence, tailoring nutrition apps to needs of specific user groups seems promising for increasing engagement.

Published: July 2021

This experimental quantitative research with a descriptive approach, which was developed in a period of time of one year with the participation of the teacher of the mathematics area and a total of 100 students who were in grade 8, arose due to the difficulties that the students presented. students in the application of the Pythagorean theorem in everyday life.
Due to this, the need arose to propose methodological strategies for the contextualization of the teaching of the Pythagorean Theorem and in this way, achieve a better understanding regarding this concept; For this reason, it was investigated with the students from a pre - test of prior knowledge which allowed to show the rhythms and styles of learning.
After this search for information, it was possible to corroborate that the students felt more comfortable when classes were held outside the classroom; In this way, the activities were more experiential and significant, which made it possible to relate the Pythagorean theorem in a transversal way with areas such as physical education, in terms of the identification of the right triangle in different spaces of the court, measurements and distances; on the other hand, in relation to the artistic area in the formation of triangles the rectangles from origami and the way to find their measurements for the creation of these figures.
The construction of this knowledge could be verified through the application of a post test which resulted in an improvement in the understanding of the practical use of the Pythagorean theorem in different contexts.

Describe los problemas sociales influyentes en la transición moral en una sociedad cambiante. Metodología/Enfoque. Cuantitativa, muestra 100 universitario. Resultados/Hallazgos. Las normas jurídicas sinónimo del derecho, han tenido diversas transiciones por medio de la historia; relevante recordar que el derecho y la moral deben ir en conjunto, no puede coexistir la una sin la otra ya que son estrechamente dependientes, porque la moral va a establecer lo que es correcto, el deber ser de determinadas conductas y es una interioridad constante, evolutiva, acorde a las condiciones. Discusión/Conclusiones/Contribuciones. El derecho ha tenido cambios históricos a través del tiempo, es inconcebible no pensar que el mismo llegue a una mutación por falta de condiciones en el futuro. Las diversas crisis por las que constantemente ha tratado de sobrevivir el planeta tales como la sobrepoblación, las pandemias que reducen la durabilidad, que inducirán al derecho a dar una vuelta y acoplarse a la civilización, llegará el tiempo, que el deber del estado ya no será asegurar la vida sino la supervivencia; en el caso del aborto, podría esta carencia de condiciones cambiar la opinión colectiva respecto a este tema de controversia mundial y pasar de ser una aberración a una solución eficaz para reducir la población, en consecuencia a un control de integrantes en la familia y la aprobación de la eutanasia como recurso que justifique una muerte digna, dejando lo ético y predomina lo conveniente; siendo la moral y el derecho piezas moldeables a las necesidades de la sociedad.
Uso del análisis multivariado factorial mixto para caracterizar variables climáticas y edáficas en sistemas agropecuarios colombianos
Authors: Castillo Vargas Julián Andrés , Cuervo Vivas Wilmer Alfonso 
Published: July 2021

Contextualización: La productividad de los sistemas agropecuarios se define como la combinación de las variables climáticas y edáficas que los caracteriza. Por tanto, el entendimiento de la interrelación de tales variables debe ser estudiado bajo un abordaje multivariado.
Vacío del conocimiento: Hasta ahora, no han sido desarrollados estudios que determinen la estructura multivariada de variables asociadas a climatología y edafología de los sistemas agropecuarios en Colombia.
Propósito: determinar la estructura multivariada de variables climáticas y edáficas en los sistemas agropecuarios colombianos usando la técnica de análisis multivariado factorial mixto (AMFM).
Metodología: Se construyó una base de datos con 167 registros de variables climáticas (altitud, temperatura y humedad relativa) y edáficas (textura del suelo, pH, actividad enzimática de la ureasa y actividad enzimática de la catalasa) de predios destinados a la producción agrícola o pecuaria primaria en 21 departamentos y 120 municipios de Colombia. La estructura de las variables anteriormente mencionadas fue analizada usando un AMFM utilizando el software Statistica, versión 7.0, siendo estas clasificadas en factores latentes. Una variable era asociada a un factor latente, cuando el valor absoluto de su correlación con el factor era mayor que 0.5.

Resultados y conclusiones: Usando el AMFM, se extrajeron cuatro factores latentes para las siete variables estudiadas, los cuales representaron un 75% de la varianza total. El primer factor se asoció positivamente con la altitud (0,950) y negativamente con la temperatura (-0,957), siendo denominado como “Climático”. El segundo factor se correlacionó negativamente con la humedad relativa (-0,790) y la actividad ureasa (-0,706). Adicionalmente, este tuvo una asociación negativa secundaria con el pH (-0,343), siendo denominado como “Ureasa-agua-pH”. El tercer factor fue denominado como “Fisicoquímica-suelo” y se correlacionó positiva y fuertemente con la textura del suelo (0,917). Variables como la humedad relativa (-0,281), pH (0,306) y actividad ureasa (0,211), también tuvieron una contribución secundaria a este factor. El cuarto factor se correlacionó positivamente con el pH (0,544) y la actividad catalasa (0,887), siendo denominado como “Catalasa-pH”. Del presente estudio se puede concluir que el AMFM reveló la estructura multivariada de variables climáticas y edáficas asociadas a los sistemas de producción agropecuaria colombiana.
