The purpose of the study: to evaluate the effectiveness of various methods of shock wave therapy in the complex treatment of athletes with lateral epicondylitis.Materials and methods: the study involved 122 people. with a diagnosis of Lateral epicondylitis, aged 20 to 45 years, of which 55 (45.1 %) women and 67 (54.9 %) men. All patients were divided into 4 groups: a control group, which included 28 people who underwent standard treatment, and 3 groups, a total of 94 people, who underwent shock wave procedures using various methods against the background of standard treatment. The examination included the collection of complaints, anamnesis, physical examination, assessment of the function of the upper limb using the QuickDASH questionnaire, assessment of tennis elbow using the PRTEE questionnaire, carpal dynamometry was performed on a MEGEON-34090 dynamometer, and statistical methods. All studies were conducted before, after treatment, as well as after 3 weeks and 1 month. after treatment.Results: shockwave therapy applied to tendons, flexors of the hand, and triceps brachii outperformed shockwaves to tendons or tendons and flexors of the hand in terms of Upper Limb Functional Activity (DASH) (p < 0,05) and score tennis elbow (PRTEE) (p < 0,05) after 3 weeks and after 1 month after treatment.Conclusion: reducing the severity of pain syndrome and functional disorders of the upper limb when performing various types of activities, when conducting shock wave therapy on the area of the tendons, flexor muscles of the hand and the triceps muscle of the shoulder indicates a faster recovery of the functions of the upper limb, which is especially important for athletes

Lateral epicondylitis: tendinitis or tendinosis?

Lateral epicondylitis is a common pathology of the musculoskeletal system resulting from repeated microtrauma of the extensor muscles of the forearm and their tendons. Lateral epicondylitis was previously thought to be tendinitis, which is an inflammatory reaction in the tendon. However, histopathologically, it has been shown to be low in inflammatory elements: macrophages and neutrophils. Thus, it is now believed that this pathology is a tendinosis, which is defined as a degenerative rather than an inflammatory process

Shock wave therapy evaluation in the complex treatment of athletes with lateral epicondylitis

Objective: to evaluate the effectiveness of shock wave therapy in the complex treatment of athletes with lateral epicondylitis in comparison with standard methods of treatment.Materials and methods: On outpatient treatment in the period from 2019 to 2022. There were 168 athletes diagnosed with Lateral epicondylitis, including 78 women (46.4 %) and 90 men (53.6 %) aged 20 to 45 years. The mean age of the patients was 31.48 ± 6.72 years. The average duration of the disease was 33.68 ± 28.17 days. To achieve the set goals and objectives, a prospective randomized controlled clinical trial was conducted. We used a clinical examination of patients, a study of carpal dynamometry of the affected arm, an assessment of the level of pain and quality of life using the QuickDash and Patient-Rated Tennis Elbow Evaluation (PRTEE) scales, statistical research methods, as well as the use of standard treatment for lateral epicondylitis and radial shock wave therapy with an assessment of effectiveness one month after treatment.Results: shock wave therapy in the complex treatment of athletes with lateral epicondylitis, compared with standard methods of treatment, improved the quality of life and reduced pain three weeks after the start of treatment and has a more pronounced effect in the long term (p < 0.05); allowed to reduce the intensity of the signal from the bone tissue (trabecular edema) according to the results of magnetic resonance imaging.Conclusion: the expediency of using shock wave therapy in the complex treatment of athletes with lateral epicondylitis is substantiated, which makes it possible to recommend its use in practical healthcare

Robust cryogenic matched low-pass coaxial filters for quantum computing applications

Electromagnetic noise is one of the key external factors decreasing superconducting qubits coherence. Matched coaxial filters can prevent microwave and IR photons negative influence on superconducting quantum circuits. Here, we report on design and fabrication route of matched low-pass coaxial filters for noise-sensitive measurements at milliKelvin temperatures. A robust transmission coefficient with designed linear absorption (-1dB/GHz) and ultralow reflection losses less than -20 dB up to 20 GHz is achieved. We present a mathematical model for evaluating and predicting filters transmission parameters depending on their dimensions. It is experimentally approved on two filters prototypes different lengths with compound of Cu powder and Stycast commercial resin demonstrating excellent matching. The presented design and assembly route are universal for various compounds and provide high repeatability of geometrical and microwave characteristics. Finally, we demonstrate three filters with almost equal reflection and transmission characteristics in the range from 0 to 20 GHz, which is quite useful to control multiple channel superconducting quantum circuits.Comment: 5 pages, 4 figure

Features of case management with neuromuscular disease during COVID-19. Clinical impression

The new COVID-19 coronavirus infection, which has become a pandemic, is a very dangerous disease, the clinical picture of which can vary from mild to extremely severe forms of the course. Currently, there are no complete data on the pathogenetic mechanism of SARS-CoV-2, but there are extensive data on the probable risk factors for the development of extremely severe forms of COVID-19. The study of such factors becomes most suitable in terms of preventing their development and influence on the course of the disease in individuals with compromised immune systems and patients with impaired neuromuscular transmission. The article describes two clinical cases of extremely severe COVID-19 in patients with impaired neuromuscular transmission. Based on the analysis of the course of diseases, the conclusions are made about the possible aggravation and mutual activation of the immunopathological process with the launch of the cascade mechanism of the cytokine storm. An assumption has been made about the influence of human leukocyte antigen (HLA) on the severity of COVID-19, which is confirmed by a positive dynamics against the background of administration of IVIG, glucocorticosteroids (GCS), virusinactivated plasma and extracorporeal detoxification methods

БИОТЕХНОЛОГИЧЕСКАЯ ТРАНСФОРМАЦИЯ ОВОЩНОГО СЫРЬЯ В ПРОЦЕССЕ НАПРАВЛЕННОГО ФЕРМЕНТИРОВАНИЯ МОЛОЧНОКИСЛЫМИ МИКРООРГАНИЗМАМИ

The article reflects the possibility of using the transformation of raw materials of vegetable type when using lactic acid organisms by the process of fermentation. The authors point out that such terms as salted, soaked and sauerkraut fruits and vegetables are widely used in vegetable processing technology and technical literature. In the canning industry there is a widespread salting cucumbers, tomatoes, pickled cabbage and beets, pickled watermelon and apples. The contamination of fresh cucumbers with lactic acid microorganisms is on average only 3-6%, and fresh cabbage from 5 to 20% of the total number of microorganisms. A significant place in the epiphytic microflora is occupied by putrefactive microorganisms and microorganisms of the genus Coli aerogenes. Contamination of vegetables microflora increases significantly during storage. As a result of the research, it was concluded that the total number of microorganisms on cucumbers that were stored for more than a day increased by 20-60 times and on cabbage with expired cabbage by 3-4 times. The article shows that the use of fermentation is one of the most popular and well-known ways to preserve fruits and vegetables from spoilage. This method relates to microbiological methods of preservation, which is based on the transformation of sugars contained in vegetables and fruits, lactic acid under the action of lactic acid bacteria, initially located on the surface of the processed raw materials. The task of the research was to study the process of directed fermentation of cabbage of white-leaved variety Slava, using strains of lactic acid microorganisms and their consortia, taking into account the degree of their mutual influence.В статье рассмотрены возможности использования трансформации овощного сырья при использовании молочнокислых организмов в процессах ферментирования. Авторы указывают, что в технологии переработки овощей и технической литературе широко применяют такие термины, как соленые, моченые и квашеные фрукты и овощи. В консервной промышленности широко распространено соление огурцов, томатов, квашение капусты и свеклы, мочение арбузов и яблок. Обсемененность свежих огурцов молочнокислыми микроорганизмами составляет в среднем всего 3-6%, а свежей капусты от 5 до 20% от общего числа микроорганизмов. Значительное место в эпифитной микрофлоре занимают гнилостные микроорганизмы и микроорганизмы рода Coli aerogenes. Обсеменение овощей микрофлорой значительно возрастает в процессе их хранения. В результате исследований был получен вывод о том, что общее число микроорганизмов на огурцах, которые хранили более суток, увеличилось в 20-60 раз, а на капусте с истекшим сроком годности капусте в 3-4 раза. В статье показано, что использование процессов ферментирования является одним из самых популярных и известных способов сохранения овощей и фруктов от микробиологической порчи. Этот способ относится к микробиологическим методам консервирования, который основан на превращении сахаров, содержащихся в овощах и фруктах, в молочную кислоту под действием молочнокислых бактерий, изначально находящихся на поверхности перерабатываемого сырья. Задачей исследований являлось изучение процесса направленного ферментирования капусты белокочанной сорта Слава с использованием штаммов молочнокислых микроорганизмов и их консорциумов с учётом степени их взаимного влияния
