The concept does not define only one quality of the material, but reflects a complex of interactions with the biological environment in which it is placed. Over time, the definition of biocompatibility has gradually changed. Dental cements are the main clinical obturating materials. First created by Wilson and Kent in 1969, glass ionomer (polyalkenoate) cements have become widely used in medicine and dentistry. The purpose of this review is to discuss the biocompatibility of glass ionomer cements. Scientific databases - PubMed and SCOPUS were used to find appropriate studies in English on the topic of this article, with the following keywords - biocompatibility, glass ionomer cements, dentistry. A time period of 2000-2021 was set to screen articles and track the progress of the biocompatibility of dental cements in the new millennium. In addition to the cited scientific databases and articles such as clinical trials, review articles, meta-analyzes, writing of the report included information from Bulgarian and foreign textbooks in English on the subject. After applying the screening criteria, 61 results were displayed in SCOPUS and 215 in PubMed. From them, selected articles that describe experimental productions with testing the properties of cements, incl. to living cells, were reviewed. Science has found that by modifying the composition of the powder and the liquid of the cement, properties and biocompatibility can be affected. Modifications with the addition of nanoparticles hydroxylapatite and silica, carbon nanocompounds, zinc ions, cellulose microfiber and nanocrystals, amorphous calcium phosphate, chlorhexidine, collagen type 1 and peptides have been reported. Cement liquid has also been improved, which changes its properties. In the given time period between 2000-2021 there is a rapid rise of development and improvement of the properties of already synthesized cements. Efforts are being made to study the biocompatibility of materials and their properties to help tissue regeneration. There is also a wider use of materials and their implementation into various fields of medicine and dentistry.","PeriodicalId":23566,"journal":{"name":"Varna Medical Forum","volume":"104 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75992811","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Aim The aim of this article is to assess the serum expression of miR-1228 in IBD patients. Materials and Methods A total of 35 patients with ulcerative colitis (UC), 35 patients with Crohn’s disease (CD), and a control group of 30 healthy individuals were studied. Serum expression of miR-1228 was tested in all through reverse transcriptase-quantitative real-time polymerase chain reaction (RT-qPCR). Results The expression in CD patients (1.91 ±2.21) was significantly higher compared to the expression in UC patients (1.15±0.64) and healthy controls (1.14±0.59). In CD patients, increased expression of miR-1228 was observed in cases with active disease, intestinal localization (L1–2.28) and penetrating phenotype (B3–3.92). In UC patients, no difference in miR-1228 expression was observed with regards to the localization and the course of the disease. Serum expression of miR-1228 correlates positively with CRP in UC patients. Conclusion In the present study, increased expression of miR-1228 was observed in cases with active disease (UC, CD), intestinal localization (CD), and penetrating phenotype (CD), while decreased expression correlated to immunosuppressive (CD) and biological (UC) therapy.","PeriodicalId":23566,"journal":{"name":"Varna Medical Forum","volume":"52 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74948774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Methods Retrospective documentary analysis of the trends for the specialty of medical opticians. Comparative analysis of the profession with other elements of the 3 O perspective, including optometrists and ophthalmologists. Results The number of medical opticians graduated from the Medical University of Varna since 2016 is 69, the largest in 2016 – 16, and the lowest in 2018 – 10. On average 20% of medical opticians are realized in practice without further qualification, while all others continue with a master‘s degree in optometry. Medical opticians most often work in an optical store, with 60% developing their own business. The number of opticians realized in medical establishments is small. The number of masters in optometry, realized in medical institutions is significantly higher and reaches 30%. Ophthalmologists are realized in medical institutions at 100% up to 3 years after graduation. Over 80% of ophthalmologists work in optical centers during their training. Conclusions As a result of an in-depth analysis of the market and the demand for qualified eye care practitioners, Medical University of Varna closes the cycle of the 3 O perspective with the following specialties: ophthalmologists, optometrists and opticians. The three categories of eye health professionals work in symbiosis to develop a comprehensive concept for prevention, prophylaxis, optical correction and treatment. Optical centers and medical institutions providing specialized care for eye diseases exchange staff, which is beneficial for the overall concept of the eye care.","PeriodicalId":23566,"journal":{"name":"Varna Medical Forum","volume":"14 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91244890","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Thanks to this development, clinical practices and laboratory techniques are moving to digital processes. The merging of these digital puzzles into one whole is the logical continuum of this trend - the creation of a 3D virtual patient. In the context of medical education, the virtual patient is defined as an interactive computer simulation of a real-life clinical scenario for the purpose of teaching, learning and evaluation. This review is limited to one area of e-learning in dentistry. It is a fact that few studies have been published as to compare the effectiveness of new virtual and augmented reality systems in dental education. Advanced simulation technology shows the potential to improve training methods and quality. With the widespread adoption and integration of these technologies into the curriculum, students can achieve a higher level of competence before embarking on a clinical practice. Scientific researches will continue to offer a variety of technologies and effective treatments. To take full advantage of modern science, new knowledge and technology must be incorporated into the core of dental education.

Stoykov","doi":"10.14748/VMF.V10I2.7892","DOIUrl":"https://doi.org/10.14748/VMF.V10I2.7892","url":null,"abstract":"The vestibular system provides the human brain with information about the angular and linear deviation of the head and body in space, as well as the sense of gravity. It is essential for maintaining adequate body position, orientation and performance of motor acts. Synchronous work with other systems – visual and proprioceptive - is observed. Disorientation, staggering and dizziness are provoked by a conflict of the information received by the different sensors. The vestibular system is a constantly engaged system. Scientific databases - PubMed, SCOPUS and MEDLINE - were used to find appropriate studies in English and other languages on the topic of this review, with the following keywords: vestibular disorder, balance, posture, adenoid hypertrophy, hearing loss. A time period of 2010-2021 was set to trace the latest discoveries in the scientific field. Fundamental pieces of scientific research from the second half of the 20th century were also included. In addition to information from the mentioned scientific databases and articles such as clinical trials and review articles, we included information and paid attention to the work of Bulgarian authors on the problems of the topic, including information from articles, abstracts of dissertations. It can be clearly concluded, based on the analyzed literature, that the ability to maintain balance is due to specific information acquired through several sensory processing systems. While vision is important for posture and balance, the ability to hear, the absence of vestibular deficits, the lack of hypertrophic processes in the adenoids contribute to the fine control and regulation of balance. Disorders in one system - visual, audio-vestibular, stomatognathic - affect others, including the whole body, because they are all connected. Patients should be offered a comprehensive diagnosis because, as has been shown many times, the pathology is interrelated and requires appropriate diagnostic methods and treatment plan. This is done in order to improve the quality of life of the patients and reduce the consequences of the disease.","PeriodicalId":23566,"journal":{"name":"Varna Medical Forum","volume":"106 6","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91480336","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are government officials and as such it is not only necessary that they perform their duties conscientiously but also that they establish a socio-cultural model of behavior during the performance of official control. The aim of the study is to research attitudes of persons working in public purpose venues towards the behavior of PHIs (Public Health Inspectors) while performing official control. 125 representatives of public purpose venues participated in the survey, of whom 45,6% were business operators and 54,4% – employees, divided into three groups according to the type of controlling agency. Half of the public officials “explain the rights and obligations“, while 48,8% do that „thoroughy and in detail“. Causes of conflict on behalf of PHIs according to 24,8% of respondents are the differences in interpretation of legislation by different inspectors, which leads to different requirements for the same thing. Over 1/3 assert that during control PHIs behave in a professional and responsible manner and are knowledgeable of the relevant legal provisions. The respondents (62,4%) view the conduct of PHIs as „lawful and impartial“. Nevertheless, the participants in the survey share recommendations for improvement of the efficacy of health control: additional professional education of civil servants, polite attitude, respect and provision of more information on PHIs’s behalf during control.","PeriodicalId":23566,"journal":{"name":"Varna Medical Forum","volume":"83 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"86316652","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Health tourism is an emerging, global, complex and rapidly changing segment that needs to be managed with modern management tools in the present era. Health tourism comprises around 5% of general tourism in the EU-28 and contributes approximately 0.3% to the EU economy (8). Health tourism has a much higher domestic share than general tourism does. Increasing the share of health tourism may reduce tourism seasonality, improve sustainability and labor quality, and may help to reduce health costs through prevention measures and decreased pharmaceutical consumption (9). Health tourism is increasing its role as a significant contributor to the development not only of regional but also of national economy (6). Despite certain tendencies in preference for individual tourism, it is expected that health tourism and health tourism destination will continue to increase their influence and take bigger part in the tourism mix in the future. In the National strategy for sustainable development of the tourism on the territory of Bulgaria /2014-2030/ the Ministry of Tourism determines tourism as a leading, structuring national industry. Tourism is a stable factor contributing to the constant optimization of Bulgarian economy through a significant share in the GDP – 12-18%. Strategic aims of Bulgaria’s are: increasing the competitiveness of the destination Bulgaria on the international tourism market by increasing the quality of the tourist product, strong brand of the destination and product specialization and diversification. One of the main priorities of the Ministry of Tourism is increasing the share of the specialized types of tourism – balneo (medical spa), spa and wellness concretely, leading to an year-round and more intensive workload (4). Aim The authors are convinced that Bulgaria has all the necessary conditions and prerequisites to present itself more purposefully and on a larger scale as a year-round tourist destination, offering a quality tourist product, placing the main focus on health tourism (medical spa, spa and wellness), which is successfully combined with all major forms of tourism (sea, mountain, cultural, gourmet, golf/. The authors support the relevant idea of the Ministry of Tourism to adapt and upgrade the existing National Strategy for Sustainable Tourism Development in Bulgaria /with a horizon of 2040 - 2050/ by placing a strong focus on health tourism, especially relevant in the world pandemic of COVID-19, when the role of health tourism (prevention and prophylaxis) in Bulgaria is recognized by all competing European countries.","PeriodicalId":23566,"journal":{"name":"Varna Medical Forum","volume":"6 2","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-08-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"91430520","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
