Objectives:
The objective of this study was to assess the immediate impact of dynamic stretching with and without floss band on hamstring flexibility in futsal players.

Methods:
Fifty-four players were included and randomly divided into tissue flossing and non-tissue flossing groups. Both groups performed dynamic stretching of the hamstring muscle, three sets of 15 repetitions. Active knee extension (AKE), straight leg raise (SLR), and sit-and-reach tests were conducted before and after the intervention. Blood samples were also drawn pre- and post-intervention to determine serum creatine kinase (CK) and lactate dehydrogenase (LDH) for recording muscle damage.

Results:
On comparing the results of both groups, the tissue flossing group had significantly increased scores (left leg P = 0.005, right leg P = 0.007) for the AKE and sit-and-reach tests (P = 0.017). The two groups had no significant SLR, CK, or LDH disparity (P > 0.05). On the other hand, within-group comparisons showed a significant disparity (P < 0.05) between all variables in both groups.

Conclusion:
The present study revealed that dynamic stretching with and without a floss band improved hamstring flexibility by increasing AKE, SLR, and sit-and-reach tests; however, results were significantly improved with a floss band. Compared to dynamic stretching without flossing, flossing resulted in better improvement of AKE and sit-and-reach test scores, while serum CK and LDH remained the same for both groups.

Background:Gram-positive opportunistic bacteria of theNocardiaspecies are responsible for a large spectrum of infections, such as pneumonia, skin infections, and more widespread conditions, including brain abscesses.Case Description:A 67-year-old male patient suffered from headache, gait disorder, and vertigo for a week before admission to our department. An enhanced magnetic resonance imaging scan revealed a mediosagittal hyperintense infratentorial lesion with concomitant compression of the fourth ventricle. The patient underwent surgical treatment with general anesthesia. The frozen section did not reveal any tumoral tissue but rather a purulent content. He was comatose on the 1stpostoperative day, and he underwent a follow-up computed tomography (CT) scan, which revealed triventricular hydrocephalus. The external ventricular drain was performed, and a follow-up CT scan revealed significant improvement of hydrocephalus. Matrix-Assisted Laser Desorption Ionization Time of Flight did not reveal any causative agent from the intraoperative content, but the 16s ribosomal DNA method confirmedNocardia cyriacigeorgica. The patient was intravenously treated with ceftriaxone and trimethoprim/sulfamethoxazole and died on the 5thpostoperative day.Conclusion:Nocardiosis presents a rare Gram-positive bacterial infection that typically affects immunocompromised hosts.Nocardia-caused brain abscesses present a significant challenge in its treatment for its atypical presentation and slow culture growth.

Ключевым фактором успешного развития страны в целом и регионов в частности выступает положительная динамика внешнеэкономических связей. Несмотря на «форс-мажорные» западные санкции, трудности в поддержании устойчивости сложившихся много ранее торгово-экономических взаимодействий, нельзя отменить ставку на расширение экспортно-ориентированного сегмента российского бизнеса. Региональные кластерные модели остаются эффективным механизмом привлечения инвестиций и активизации экономической интеграции со странами-партнерами. Так, развитию экспортного потенциала Калужского региона, обладающего соответствующими характеристиками и возможностями, способствует формирование транспортно-логистического кластера. Закрытие границ, фактическое ограничение торговли с западными странами и санкции, введенные против РФ, безусловно, повлияли на состояние транспортной логистики региона. Ощутимым стало увеличение стоимости запчастей, сервисного обслуживания грузового транспорта и самих транспортных средств. Подобные изменения неизбежно ведут к росту себестоимости рейсов, соответственно, повышаются и цены для заказчиков грузоперевозок, что приводит к удорожанию поставляемой продукции, понижению реальных доходов потребителя. Реализация перспектив транспортно-логистического кластера Калужской области возможна исключительно при условии учета новых реалий и принятия адаптационных решений.

Rationale: Age-related macular degeneration in the modern world is one of the leading problems leading to blindness. It is a rapidly progressive disease characterized by damage to the central area of the retina.Objective: The aim of the study was to evaluate the morphological and functional parameters of the retina after surgical treatment of submacular hemorrhages against the background of anti-vasoproliferative therapy in patients with a wet form of age-related macular degeneration.Methods: The study was conducted on the basis of the Ophthalmology Center NMHC named by Pirogov (Moscow). It included 90 participants with an active form of age-related macular degeneration. The average age of the patients was 71.3 ± 8.5 years, including 50 women aged 61 to 82 years and 40 men aged 74 to 78 years. The rationale for the use of the “treat and extend” strategy in this work is the possibility of using fewer intravitreal injections compared to a fixed scheme that gives similar results of visual functions.Conclusion: It can be concluded that the preservation of the vitreous body during minimally invasive vitreoretinal intervention allows you to adhere to the “treat and extend” mode without reducing the inter-injection interval.

Published: November 2024

New drugs and methods of early diagnosis of malignant tumors of the visual organ have appeared in the last decades. Nevertheless, the problem of untimely diagnosis and treatment of these diseases remains in practical ophthalmology, which leads to more radical and less organ-preserving methods of treatment and, as a consequence, to the deterioration of cosmetic and functional results in subsequent eye prosthetics.Aim. To analyze and discuss the literature on the following topics: ocular prosthetics and ophthalmic oncology using available databases.Material and methods. Optimization of domestic and foreign scientific papers using eLibrary, PubMed, ScienceDirect and Google Scholar databases.Results. The 52 most relevant sources of domestic and foreign literature were analyzed.Conclusions. Having analyzed the literature data in domestic and foreign sources, we can conclude that the world medical community has not fully disclosed the issue of eye prosthetics in patients after oncological treatment. More research and practical recommendations are needed in this area. The use of a staggered prosthetic method, as well as the shape of the eye prosthesis, taking into account the individual characteristics of the conjunctival cavity, will help to achieve the best results.

Published: November 2024

Diabetic retinopathy is one of the most severe complications of diabetes mellitus, requiring the participation of doctors of various specialties: endocrinologists, diabetologists, therapists, cardiologists, surgeons, anesthesiologists and others.The task of an ophthalmologist is to identify pathological changes in the eye associated with diabetes mellitus and prescribe appropriate treatment.There are three main methods for treating diabetic retinopathy: laser coagulation of the retina;intravitreal injections of anti-VEGF and glucocorticoids;vitreoretinal surgery.This literature review examines the use of vascular endothelial growth factor inhibitors in the treatment of diabetic retinopathy. In particular, it discusses the most relevant drugs, the most important studies on the therapy of DR and diabetic macular edema, as well as a post hoc analysis of these studies. In addition, the role of these drugs in the therapy of refractory DME is discussed.

Objective: to evaluate the role of ischemia in the pathogenesis of diabetic vitreopapillary traction syndrome.Material and methods: The analysis is based on a sample of 30 patients with diabetic vitreopapillary traction syndrome. The study included a standard ophthalmological examination, color doppler mapping, fluorescent angiography. All patients underwent three-port vitrectomy to eliminate traction syndrome.Results: The results of the obtained data indicated that patients with diabetic vitreopapillary traction syndrome had significant changes in the hemodynamics of the eye compared to the normal parameters. A significant difference in a blood flow parameters in the posterior short ciliary arteries system was recorded in eyes with vitreopapillary traction syndrome compaired to paired eyes.Conclusion: The results of the studies indicate that patients with diabetic vitreopapillary traction syndrome have significant changes in regional hemodynamics: a decrease in blood flow velocity in the central retinal artery, posterior short ciliary arteries and an increase in peripheral vascular resistance, which indicates ischemia of the optic nerve head and may also be one of the reasons for the development of vitreopapillary traction.

Rhegmatogenous retinal detachment (RRD) is one of the general determinants of the primary sight disability. However, employable people represent the majority of patients with RRD.Over the past 50 years, retinal detachment surgery had rapid progress, and the rate of success surgery increased up to 90% and higher. However, reducing the risks of reoperations, improving functional outcomes and increasing postoperative visual acuity remain topical issues at present.The main reason for second surgical interventions is progression of the proliferative vitreoretinopathy, which can lead to epiretinal membrane, macular oedema, and to recurrence of the retinal detachment.We reviewed current literature studies that report the results of internal limiting membrane peeling in cases with RRD and other alternative techniques aimed at reducing the risk of mentioned above postoperative complications.
ACTUALIZATION AUTOSCLEROKERATOPLASTY IN CORNEAL DISEASES
Authors: Laptev N. E. , Lapteva A. V. 
Published: November 2024

Rationale: Diseases of the cornea of the eye account for a quarter of the total incidence of ophthalmological pathologies, which, in turn, are detected in 11% of all cases of appeals. These pathologies are dangerous, since 75% of patients with this group of diseases may subsequently develop visual impairment, up to its complete loss. In case of severe lesions, surgical intervention is inevitable, while both allo- and autografts can be used for corneal flap transplantation, with the sclera being the most preferred option in this case. Autosclerokeratoplasty seems to be a modern, most rational method for treating severe pathologies of the cornea, and updating this method seems to be a very important task.Objective: updating the method of autosclerokeratoplasty for corneal lesions using a clinical example of the successful use of the method for ulcerative lesions of the cornea.Methods: An analytical work of scientific literature for the last 10 years was carried out, PubMed databases were used, including PubMed Central, Google Scholar, CyberLeninka. The search was conducted using the keywords “autosclerokeratoplasty”, “autosclera”, “corneal ulcer”, etc.To characterize the possibility of using autosclerokeratoplasty in clinical practice for corneal damage, a clinical case is given, medical documentation was used for the analysis: outpatient card, medical history, instrumental and physical examination data. The data were systematized using modern methods of information analysis.Results: The method has many advantages over other methods of surgical treatment of corneal pathologies: 1) performing anterior lamellar keratoplasty of the cornea allows to reliably close the optical zone, eliminating the threat of perforation and in some cases improve the patient’s vision, 2) in case of a threat of rejection of the lamellar keratograft, it is possible to take a second peripheral fragment of the cornea under the upper eyelid, 3) suture fixation of the autoscleral flap over the area ofthe corneal defect under the upper eyelid allows to achieve an aseptic course of the process, 4) the location of the area for taking the lamellar keratograft under the upper eyelid does not worsen the cosmetic appearance of the operated eye. Based on a clinical case with a severe patient, the potential of this operation is visible.Conclusion: autosclerokeratoplasty is a progressive method of surgical treatment of corneal pathologies. Since the incidence of these pathologies is high, and the risk of disability is high, the actualization of this method is most important. At the same time, all the current data on the possibilities of autosclerokeratoplasty are provided based on scientific literature and a clinical case.

Published: November 2024

Usually, the recurrence rate of regmatogenic retinal detachment (ROS) after surgery ranges from 3% to 30%. In cases where the disease recurs after successful surgery, in 60% of cases the main factor is the progression of proliferative vitreoretinopathy (PVR), which makes it one of the most severe complications that can occur in the postoperative period. In addition, after removal or absorption of a tampon agent (in particular, endotamponade with silicone oil), recurrent retinal detachment may occur due to the inability to detect retinal rupture during surgery.Objective: this study is aimed at evaluating the effectiveness of diagnostic methods used during operations for regmatogenic retinal detachment. After completing the standard stages of central vitrectomy, the group of patients was divided into two equal groups: the first group included patients who received the double contrast method, and the second group (control) – patients who underwent the traditional surgical method.Results and discussion: in patients of the control group, there was a significant increase in the number of relapses of ROS. In addition, it was found that an increase in the number of retinal tears correlated with a greater likelihood of macular involvement; Statistical evaluation has shown that the absence of AST and tight adhesion of the posterior hyaloid membrane to the retina and small retinal tears increase the risk of recurrence of ROS due to the progression of PVR.
Motivation, Learning Styles and Strategies in English Language among First-Year College Students in Public HEI’s in Sulu
Authors: Aurizia Duha Siraji  
Published: November 2024

English, as the most frequently spoken second language, and sometimes referred to as the global lingua franca, acts as a bridge for communication across cultures and nations. Learning English is a strong tool that allows people to fully participate in the global society by encouraging understanding, collaboration, and personal growth. This descriptive-comparative paper analyzed the motivation, learning styles, and learning strategies of first year college students from public higher education institutions (HEIs) in Sulu, Philippines. Participants were purposively sampled (n=200) to participate in the study. Findings indicated that first year college students in the province were integratively motivated to learn the English language. They particularly engaged in psychological and sociological learning styles through speaking to fluent English speakers, understanding emotional cues, reflection, and self-assessment. They engage in metacognitive (planning, organizing thoughts) and cognitive (assessment, analysis) to learn and understand English. Educators should adopt a holistic approach to teaching English, one that motivates students, respects their individual learning styles, and equips them with effective learning strategies. Such an approach could likely lead to more effective and meaningful language learning experiences, which could improve students' proficiency and confidence in using English.
A Study of Bilingual Development of Subject Realization of a Mandarin-English Bilingual Preschool Child from China to Australia

Published: November 2024

This article traces the developmental trajectory of bilingual subject realization of a Mandarin-English bilingual child from China to Australia from age 3;04 to 5;05. There is an assumption that age 3 is the dividing line between Bilingual First Language Acquisition (BFLA) and Early Second Language Acquisition (ESLA). Determining similarities and differences between them is of great theoretical and methodological significance. While BFLA studies show consistent results under the condition of adequate input and meaningful interaction, ESLA studies indicate that these children proceed their early English differently from BFLA. Previous studies mainly focused on young children’s English development in English-speaking countries without prior English input. However, an increasing number of children migrate to English-speaking countries after age 1 with limited English input. This study examines whether there is qualitative difference between BFLA and ESLA children’s bilingual subject realization. Drawing upon the naturalistic data before and after the child’s migration from China to Australia and CLAN analysis, the 25-month longitudinal case study indicates that the ESLA child’s bilingual subject realization developmental trajectories are qualitatively similar but quantitatively different from Mandarin-English BFLA peers. This study could be the first of its kind by investigating a bilingual child who acquires two languages with changed environmental language (Lε), contributing theoretically and practically to early childhood bilingualism.

The impact of the language of instruction on academic achievement is a critical issue, particularly in multilingual settings. This study investigates how using French as the medium of instruction affects the academic performance of first-year physics and chemistry students at Moroccan universities. The research, conducted at Mohamed I and Abdelmalek Essaadi Universities, involved 365 students and 20 teachers. Data were collected through questionnaires and semi-structured interviews. We conducted a correlation analysis to examine the relationship between French proficiency and academic performance in physics and chemistry. A frequency analysis identified common difficulties students face when studying these subjects in French. An ANOVA determined if using French as the medium of instruction significantly impacts academic performance. The results show a significant relationship between students' proficiency in French and their academic performance in science subjects taught in French. Our analysis indicates that instruction in a non-native language has a negative impact on academic success. Many students expressed discomfort with French, citing difficulties with scientific vocabulary and comprehension. Teachers corroborated these challenges, noting that students' limited French proficiency impedes their understanding of complex scientific concepts, contributing to higher failure rates. Additionally, a strong positive correlation was found between French language proficiency and academic performance in physics and chemistry. Students with lower proficiency in French tend to have poorer academic performance in these subjects.

Ventral hernias (VH) continue to be one of the most common surgical pathologies in planned and emergency surgery. Surgical treatment of large VH (≥10 cm) requires the use of traumatic surgical techniques in order to align the edges of the hernia defect and restore the integrity of the anterior abdominal wall.
Objective — to assess the effectiveness of the botulinum toxin type A (BTA) injections and to study the peculiarities of their administration into the muscles of the anterior abdominal wall in patients with large VH in the preoperative period.
Materials and methods. A prospective cohort study included 66 patients with large VH, primary (PVH), and incisional (IH). From June 2017 to August 2024, all patients underwent treatment and received injections of 100 units of BTA into the anterior abdominal wall muscles in the preoperative period. The patients’ average age was 58.98±9.48. There were 23 men (34.8%) and 43 women (65.2%). Before BTA, the average width of the hernial defect in PVH patients was 12.29±1.93 cm, whereas IH was 13.46±2.06 cm. All patients underwent surgical intervention for their hernias 4—5 weeks after the injection of BTA.
Results. No complications were detected throughout the BTA administration or the 4—5 weeks of observation before the surgical hernia repair. After injection, the length of the anterior abdominal wall muscles increased by an average of 1.7 cm (min 0.1 cm, max 4.01 cm) on each side. Patients with PVH had an average hernial defect width reduction of 4.17±0.68 cm, whereas those with IH had an average reduction of 5.14±0.75 cm (p <0.001). After BTA administration, the volume ratio of the hernia sac to the abdominal cavity decreased from 4.97±3.55% to 3.70±2.77% in patients with PVH (p=0.008) and from 5.59±3.71% to 4.21±2.88% in patients with IH (p=0.008).
Conclusions. The administration of 100 units of botulinum toxin type A in the preoperative period consistenly increases the length of the abdominal wall muscles, reduces the width of the hernial defect, and enhances the possibilities of further surgical treatment of large VH using laparoscopic technologies.
