The article presents the results of a research on world and European experience of foresight research. Attention is focused on the organization of foresight research and institutional support of foresight in EU countries. The authors substantiate the necessity of expanding the practice of foresight research in Ukraine in the conditions of those changes in the nature of the world economy that occur under the influence of the COVID-19 pandemic and on the verge of upcoming change in the Kondratiev long cycles. Current trends in the world economy facilitate access to foreign markets, but at the same time create certain risks for national economies. Increasing competition between domestic and foreign producers for many countries means the bankruptcy of domestic enterprises, especially medium- and high-tech ones, which are unable to compete with corporations that are more powerful. Domestic prices for almost all goods increasingly depend on prices in other markets, which can form imbalance between the cost and price of labor and destroy the labor market, increasing migration of the working population, especially those with high levels of human capital, which reduces the country's opportunities in education, science and production and even multiplicatively affects economic growth. In these conditions, it becomes extremely important to determine the guidelines for future economic development and society, which actualizes the whole range of foresight research. For Ukraine, where foresight research is limited, the experience of those countries where foresight has become an integral part of strategic planning is vital. The article is devoted to the study of this experience, which identifies the basic organizational measures of foresight research, the main aspects of foresight institutionalization and the problems that hinder the development of foresight in Ukraine. The publication was prepared within the research project on "Institutional and organizational basis for the foresight research "Economy of Ukraine – 2050” « (state registration No 0121U108846).
History of medicine in Ukraine during the Mesolithic period: climatic and socio-religious origins of the development of empirical medicine
Authors:   Shupyk National Medical Academy of Postgraduate Education, Mazur I.P.
Published: April 2021

The development of empirical medicine of the Mesolithic period is closely connected with the worldview, religious beliefs and beliefs of primitive men. The difficulty in studying medicine of this period is due to the lack of written sources of information. The use of the method of reconstruction on the basis of multifactor analysis and comparison of historical events, the results of archaeological, climatogeographic, paleobotanical, paleozoological, paleopathological and ethnographic studies, socio-economic activities of people, their religious beliefs and worldview allows to present the peculiarities to their health. An important source of information is the art of primitive society, its symbolic and symbolic system, which most accurately reflects the worldview and beliefs of man, the attitude to their health.

Choosing the best drug for the treatment of cardiac patients remains one of the most important aspects of medical practice. The purpose of this review is to select the optimal beta-blocker for the treatment of patients with chronic heart failure and patients with acute myocardial infarction by comparing the efficacy of carvedilol and metoprolol succinate, as both drugs significantly reduce mortality rates and reduce hospitalization. The results of meta-analyzes, randomized trials comparing the efficacy of carvedilol and metoprolol succinate in the treatment of patients with heart failure with reduced ejection fraction and patients with acute myocardial infarction were analyzed. Conflicting data received. According to the study “Effect of carvedilol vs metoprolol succinate on mortality in heart failure with reduced ejection fraction”, a meta-analysis published in the American Journal of Cardiology in 2013, carvedilol is significantly more effective than metoprolol succinate in treatment of patients with heart failure with reduced ejection fraction and patients with acute myocardial infarction, while meta-analyzes of 2015 and 2017 showed no preference for carvedilol over metoprolol succinate. Based on the results, concluded that the data obtained is not sufficient to argue that carvedilol is more effective than metoprolol succinate for this category of patients in terms of reducing the risk of all-cause mortality, cardiovascular mortality, and reducing hospitalization. This problem requires further extensive research.

Interdisciplinarity of History of Medicine and Narrowness of the Modern Domestic Historical and Medical Field
Authors:   Kharkiv National Medical University, Robak I.Yu.
Published: April 2021

Author provided a classification of modern historical and medical knowledge. Further, the author convincingly proved that certain distortions and disproportions had been developed in the modern domestic historical and medical discourse. This conclusion has been done basing on analysis of publications and speeches at scientific forums of Ukrainian historians of medicine in recent years, and applying problem-chronological as well as comparative-historical research methods. Medical researchers have been trying to undertake a reconstruction of socio-cultural components of the discipline, but without sufficient mastering historical instruments. As a result, works of low quality have published. The author recommended physicians who study History of Medicine to investigate problems of development of medical science and practice, and leave problems of social relations for professional historians.

As the development of approaches to correct compliance disorders in patients with schizophrenia remains relevant today, we examined 112 patients and studied both clinical and psychopathological and pathopsychological features on the background of treatment with neuroleptics. To identify and evaluate clinical and psychological characteristics of patients with varying degrees of adherence to treatment with neuroleptics. For implementation of the objectives of the work both clinical and psychological and psychodiagnostic examination of the mnestic and emotional sphere, personal characteristics and self-esteem in patients were used.The use of the scale of drug compliance gave the opportunity to single out groups of patients with varying degrees of compliance. The application of the technique to study the side effects of antipsychotics revealed a relation between severity of side effects of medications and patients’ compliance. Along with psychopathological features, the group with noncompliance was characterized by the maximum severity of disorders in cognitive sphere. Medical treatment was accompanied with changes in emotional sphere in the form of objective signs of affective discomfort, least pronounced in patients with full compliance. The personal features differing in patients with varying degrees of adherence to treatment were established. Analysis of color associations based on color test relationships with emotionally significant individuals and concepts revealed the most pessimistic associations with negative values of colors in relation to health and disease in patients with noncompliance. Self-assessment of patients with noncompliance was characterized by the lowest rates in contrast to patients with partial and full compliance. The revealed psychodiagnostic features make up pathopsychological complexes of symptoms, which serve as differential diagnostic criteria of compliance of varying degrees.
Sanitary and Epidemiological Portrait of the Medieval City
Authors:   Kharkiv Medical Academy of Postgraduate Education, Oparin O.A.
Published: April 2021

The work shows that the medieval Western European city was characterized by an extremely low sanitary condition, manifested in the absence of a sewerage system and water supply, in the absence of street paving, unsanitary conditions of houses and streets. The extremely low level of personal hygiene of the inhabitants of the medieval city, a high level of infant mortality, widespread alcoholism, and low life expectancy are shown. It was found that one of the leading reasons for the low sanitary state of medieval cities and the level of personal hygiene was the unbiblical teaching of the medieval church about the immortality of the soul, according to which the flesh needed constant mortification and neglect, and caring for it and the comfort of dwellings was considered a mortal sin.

Published: April 2021

Іnflammatory bowel diseases are among various chronic processes, which, in the case of inadequate diagnosis and irrational treatment, eventually lead to highly unfavorable consequences. Thus, the timely establishment of the diagnosis, as well as the prescription of effective therapy and the subsequent careful follow-up of patients with inflammatory bowel diseases is the key to prolongation of the patients’ wellbeing and prevention of the occurrence of severe complications. Due to the possible increase in the prevalence of these pathologies in the future, close and effective cooperation between specialists and primary care physicians is extremely important nowadays. Unfortunately, there are currently no tools that can be used by primary care physicians to improve the routing of patients with inflammatory bowel disease. However, close and clear communication between primary and secondary healthcare specialists should become an integral part of health care systems, including that in our country.

The combination of socially significant common chronic non-infectious diseases of internal organs, the interaction of their pathogenetic links quite often leads to the development of complications that affect the course of the main nosology. Among these tandems, chronic pancreatitis and hypertension are considered — calcium-dependent diseases, the comorbidity of which can affect the disturbances in calcium metabolism, thereby contributing to the formation of osteopenic conditions. A number of researchers have established that the development of diseases such as chronic pancreatitis and hypertension, and their complications (namely, osteoporosis) can be the result of the presence of candidate genes, the unfavorable polymorphism of which can provoke changes in the pathogenetic directions of the diseases course.

Published: April 2021

Introducción: El objetivo de este estudio fue evaluar los cambios morfológicos en la zona intrarticular y extrarticular de la porción larga del bíceps de pacientes sometidos a una tenodesis subpectoral.
Materiales y Métodos: Se incluyeron 9 pacientes con diagnóstico de tendinopatía de bíceps, a quienes se les realizó una tenodesis subpectoral de la porción larga del bíceps. La porción eliminada del tendón del bíceps se colocó en formalina al 10% y se dividió en 2 segmentos. Quedaron definidas la zona proximal, desde la inserción supraglenoidea hasta el borde proximal del pectoral mayor y la zona distal correspondiente a la inserción del pectoral mayor. Los segmentos se tiñeron con hematoxilina y eosina, y se evaluaron histológicamente utilizando el puntaje de Bonar.
Resultados: Macroscópicamente todos los tendones estaban engrosados en la región proximal. En la evaluación histológica, entre las variables más relevantes evaluadas por el puntaje de Bonar, el puntaje de morfología celular en la zona proximal fue significativamente más alto que en la zona distal (p <0,0001).
Conclusiones: Nuestros hallazgos mostraron niveles más altos de patología dentro del bíceps proximal, lo que respalda la eliminación de dicho segmento cuando se realiza un procedimiento para la tendinopatía crónica del bíceps, lo cual se puede lograr con una tenodesis subpectoral.

The southern river otter (Lontra provocax): insights from the perspective of Andean Patagonian ethnozoology
Authors: Pozzi Carla , Ladio Ana H.
Published: April 2021

Animals play a significant role in many cultures around the world. The southern river otter Lontra provocax (known locally as the “huillín”) is endemic to southern Argentina and Chile, and is currently in danger of extinction. Mapuche communities have always lived closely alongside their animal resources, generating unique bonds with them. The objective of this work is to obtain an overview of the importance given to this species in the literature of the region with regard to the nature-culture connection. A systematic bibliographical review was carried out using reference libraries and web browsers. From all the sources analysed, 110 were selected which held biocultural information. The main approach used was ecological; however, the ethnohistorical texts provided the richest information on the bond between this otter and humans. The Mapuche name “huillín” appears in all the publications analysed, showing its continuity over time. Of all the zootoponyms found, 87.5% were Chilean and 12.5% were Argentine. The Argentine case is found in Nahuel Huapi lake, and is worthy of note as its name could involve the huillín. The results of this work increase our knowledge of the biocultural heritage of our region, and enable us to reflect on the associated historical and political processes.
Theatrical arts of Jews in Belarus
Authors: Batsiayev Vasil F.
Published: April 2021

Introduction. Spiritual culture occupies an important place in the life of the Jews in Belarus. Its important component is art, including theatrical. In Belarus since the 16th century there are many different Jewish theatrical associations, but they have not been sufficiently studied to date. There are no special works on this problem in the ethnological literature. At the same time, the analysis of the process of their creation, repertoire and activity, determination of forms and structure is of great scientific interest and is of great practical importance. Research Methods. The structural method was applied for studying Jewish theater associations in Belarus. This method allowed to identify their forms (clubs, enterprises, studios, theaters) and structure. To consider the process of creating theater associations, activities in different historical periods, the comparative-historical method was applied. The functional method was also used, with the help of which the functions of theatrical associations were clarified. Results. On the basis of the analyzed scientific literature, the article examines the process of creating Jewish theatrical associations in Belarus, identifies their forms, structure, clarifies the drama and activities in various historical periods. Theatrical associations are also characterized, which used in their performances works of modern and classical drama, which absorbed the best features of Jewish culture on the Belarusian land, widely turned to Jewish literature, staged the first plays of many authors. Discussion and Conclusion. As a result of the study, it was revealed that the theatrical art of the Jews of Belarus began to develop in the 16th century, and the repertoire of Jewish theatrical associations (clubs, enterprises, studios and theaters) consisted mainly of Jewish classical and Soviet drama, Western European comedies. They also staged a high tragedy, vaudeville and operettas. The performances of these associations are characterized by a striving for bright stylized folk shows with sharp satirism, grotesque, buffoonery, carnivalism. Jewish theatrical art has made a notable contribution to Jewish culture. It contributed to the ideological, aesthetic and international education of the people.
Revolutions in Norm-Creating: Law, Morality, Religion
Authors: Koval Ekaterina A. , Sychev Andrey A. , Zhadunova Natalia V.
Published: April 2021

Introduction. The emergence of social norms is usually described as a spontaneous, objectively conditioned process. However, the norm-creating approach to the study of the indicated problem allows obtaining a fundamentally new optics of socio-philosophical studies of normativity. The purpose of this article is to analyze the position of various normative regulators (law, morality, religion) in the value-normative hierarchy, conditioned by the rule-making activity of individual and collective subjects. Materials and Methods. The theoretical and methodological basis of the study is a systematic approach that allows considering law, morality and religion as elements of a single value-normative space. To conceptualize norm-making revolutions, the model of the social imaginary in the interpretation of C. Castoriadis and Ch. Taylor is used. Results. Three norm-creating revolutions are described: moral, religious and legal, each of which is characterized by the priority of the corresponding normative regulator. The moral stage was preceded by the stage of the emergence of social norms and the primary social imaginary, characterized by the priority of the group. The moral revolution was marked by the internalization of external norms into individual consciousness and the isolation of moral norms from other social normative regulators (that had not been differentiated in the syncretic consciousness of an archaic person). A religious revolution is characterized by other subjects of rule-making (God, Councils, bishops, etc.), the switch in the value hierarchy from an individual to a group, the formation of a new type of social imaginary. A legal revolution, which entailed a certain degree of legalization of morality and religion, is associated with the development of the ideas of human rights, justice, equality in the social imaginary. It is characterized by the priority of the individual interests and the expansion of the circle of subjects of norm-creating, although their degree of participation in norm-making activities can be significantly differentiated. Discussion and Conclusion. Probably, the next norm-creating revolution has already begun, but it is not yet possible to fully understand its specifics. Most likely, the group again will occupy the center of the social imaginary, pushing the individual to the periphery of the value-normative space.

Reservoir simulation models are used to design oil field developments, estimate efficiency of geological and engineering operations and perform prediction calculations of long-term development performances. A method has been developed to adjust the permeability cube values during reservoir model history-matching subject to the corederived dependence between rock petrophysical properties. The method was implemented using an example of the Bobrikovian formation (terrigenous reservoir) deposit of a field in the Solikamskian depression. A statistical analysis of the Bobrikovian formation porosity and permeability properties was conducted following the well logging results interpretation and reservoir modelling data. We analysed differences between the initial permeability obtained after upscaling the geological model and permeability obtained after the reservoir model history-matching. The analysis revealed divergences between the statistical characteristics of the permeability values based on the well logging data interpretation and the reservoir model, as well as substantial differences between the adjusted and initial permeability cubes. It was established that the initial permeability was significantly modified by manual adjustments in the process of history-matching. Extreme permeability values were defined and corrected based on the core-derived petrophysical dependence KPR = f(KP) , subject to ranges of porosity and permeability ratios. By using the modified permeability cube, calculations were performed to reproduce the formation production history. According to the calculation results, we achieved convergence with the actual data, while deviations were in line with the accuracy requirements to the model history-matching. Thus, this method of the permeability cube adjustment following the manual history-matching will save from the gross overestimation or underestimation of permeability in reservoir model cells.

Waterflooding effectiveness of the structurally complex carbonate reservoir in the Tournaisian-Famennian formation of the Magovskoye field is studied. This formation is characterised with hardened geological conditions, which affects the development efficiency. The work includes analysis of the history and current state of the formation development, production and injection well performance, the reservoir natural energy contents, the reservoir pressure performance across wells, formation geology and lithofacies structure. A correlation was established between the well performance and lithofacies heterogeneity of the formation. A combination of boundary and marginal flooding systems is arranged at the formation target, which shows low efficiency. The wells located in the edge reservoir areas exhibit low reservoir pressures; these areas feature low reservoir properties. Concurrently, there is a difference between the upper and lower parts of the section. The wells drilled into the lower part of the section show a positive water production performance and positive energy level, which is associated with the aquifer influence. The wells drilled into the upper part of the section show lower reservoir properties, higher compartmentalisation and no aquifer influence. The wells located in the areas with low reservoir pressures were reviewed, the reasons for the depleted content of energy were identified and research proposals were provided. Furthermore, we considered the well intervention operations performed at the formation in question and at formations of similar fields in the corresponding geological field conditions, and identified operations with the highest technological effects. As a result of the studies, well intervention operations were proposed, subject to the specific structure of the lithofacies zones and the nature of the relationship between production and injection wells. It will result in enhancing the waterflood system effectiveness and affecting the target development efficiency, in general.

Morphology, abundance and the invasiveness of coral-killing sponge Chalinula nematifera (Porifera: Demosponigiae) from Con Dao National Park, Vietnam
Authors: Quang Thai Minh
Published: April 2021

This is the first study on morphology, abundance and invasion of coral-killing sponge Chalinula nematifera (De Laubenfels, 1954) from offshore waters in Con Dao islands, Vietnam. The results of the study show that the morphology is similar to that in the Western Pacific, but differs in skeletal structure compared to the description in the Eastern Pacific. The density of C. nematifera (average ± standard deviation) is 2.02 ± 5.03 colonies per 100 m2 (present at 12/15 survey stations) with the number of colonization belonging to diameter group 5–20 cm. They invade 30 species belonging to 23 genera of Scleractinia corals (44.7% on foliose/laminar and encrusting coral, 23.86% on massive coral and 21.97% on branching coral). The ability to invade corals of C. nematifera does not limit the host. So, this is considered a potential hazard to the East Vietnam Sea coral reefs in the future.

Authors: KIRLANGIÇOĞLU Cem
Published: April 2021

Throughout history, human beings have lived to survive, have struggled to have a job and have enough income for a better life. But at the point we have reached today, people's quality of life not only depends on wealth and employment, but also on many subjective factors, including the conditions of the environment in which they live, physical and mental health, education, recreation, security, leisure, freedom, human rights, social belonging and happiness level. Although this situation is related with the individuals at micro scale, it is one of the important focal points of central and local governments on macro scale. For administrators, revealing regional differences in well-being is an important criterion for eliminating social inequalities. There are many different multi criteria decision making based studies calculated the index of quality of life in 81 provinces of Turkey in accordance with 11 dimensions and 41 indicators determined by Turkstat. The aim of this study is to compare the quality of life studies and rankings of cities based on six different statistical methods. GIS based IDW interpolation technique was used to understand the spatial distribution of well-being index and make an accurate comparison of the calculation methodologies. As a result of the study, it was seen that different methods performed on the same data gave very different results from each other.
Multirotoros pilóta nélküli légijárművek háromdimenziós repülési pályáinak számítógépes tervezése és szimulációja

A pilóta nélküli légijárművek (UAVk) repülése során, főként városi, épített környezetben a felszállás és a leszállás során a repülési pálya megtervezése és a lehetséges repülési pályák közül a leginkább megfelelőnek a kiválasztása kiemelkedően fontos és egyben kritikus feladat is. A megfelelő repülési pálya megtervezésekor elsõsorban tekintettel kell lennünk a repülésbiztonságra, valamint a repülési feladat sikeres végrehajtására is. Az UAVk repülési pályáinak tervezése különösen fontos akkor, ha úgy a felszálló-, mint a leszállóhelyen korlátozott fizikai méretek állnak rendelkezésünkre, így adott esetben, akár extrém leszállópályák tervezésére is szükségünk lehet. A szerző célja olyan háromdimenziós (3D) repülési pályák számítógépes megtervezése, amelyek alkalmasak lehetnek akár multirotoros, akár hagyományos, merevszárnyú elrendezéssel bíró UAVk fel- és leszállásának végrehajtására úgy kézi, mint automatikus irányítások esetén is.
A Trump elnökség tanulságai
Authors: Matus János
Published: April 2021

2020 több szempontból is különleges elnökválasztási év volt az Egyesült Államokban. Mindenekelõtt különlegessé tette a példa nélküli koronavírus járvány és annak súlyos emberi és anyagi következményei, amelyek az átlagosnál súlyosabban érintették az ország lakosságát. Különlegessé tette továbbá a 2020-as választást a felfokozott társadalmi és politikai megosztottság, amely az erőszak alkalmazását is előidézte. A jelenlegi helyzethez vezetõ folyamatok már korábban, még az Obama-adminisztráció elõtt elkezdődtek. Obama nyolc éve alatt a Demokrata Párt dominanciáját felváltotta a Republikánus Párt többsége a Kongresszus mindkét Házában. Ez a törvényhozói hatalomban bekövetkezett változás felfogható a választók jelzéseként, hogy változásokat akarnak. 2016-ban Donald Trump megválasztásával bekövetkezett ez a változás. A tanulmány a Donald Trump alkalmasságáról szóló viták bemutatására tesz kísérletet. Azokra avéleményekre támaszkodik, amelyeket az adminisztrációból önként távozott vagy az elnök általeltávolított munkatársak fogalmaztak meg. Ismerteti néhány hagyományos konzervatív republikánus kampányszakértő állásfoglalását, amelyek kritikát fogalmaztak meg Trump elnök személyével és politikájával kapcsolatban. A Donald Trump elnökségét értékelő egyik legalapvetõbb dokumentum a Mueller-jelentés, a tanulmány fontos forrása volt. A jelentés két kötetben, több mint négyszáz oldal terjedelemben foglalja össze a 2016-os választásba történt orosz beavatkozás vizsgálatának tapasztalatait. Végül bemutatja  az Amerikai Pszichiátriai Társaság tagjainak elemzését Donald Trumpkarakteréről és az elnöki pozíció betöltésére való alkalmasságáról.

Background: Sore throat and hoarseness frequently occur following general anesthesia with tracheal intubation and are effectively reduced when dexamethasone is used prophylactically. Alchemilla vulgaris in glycerine (Neo Mucosal Activator®) suppresses inflammatory response, possibly relieving sore throat.Methods: We enrolled 94 patients (age ≥ 18 years) scheduled for thoracic surgery using double-lumen tube intubation. Before intubation, 0.2 mg/kg of dexamethasone was administered intravenously and 2 ml of normal saline was sprayed into the oropharyngeal cavity (Group D; n = 45), or 0.04 ml/kg normal saline was administered intravenously and 1 g of Neo Mucosal Activator® mixed with 1 ml of normal saline was sprayed into the oropharyngeal cavity (Group N; n = 43), in a double blind and prospectively randomized manner. Postoperative sore throat and hoarseness were recorded using a numeral rating scale and a 4-point scale to detect a change in voice quality following tracheal extubation (at 1, 6, and 24 h). The primary outcome was the incidence of sore throat at 24 h following surgery. The secondary outcomes were incidence and severity of sore throat and hoarseness.Results: There were no significant differences in the incidence of sore throat at 24 h following surgery (57.8% vs. 46.5%; P = 0.290) or in the incidence and intensity of sore throat and hoarseness at 1, 6, and 24 h following surgery between the groups. Conclusions: A. vulgaris in glycerine did not significantly differ from dexamethasone for preventing sore throat and hoarseness owing to intubation.
Review of compatibility between SANS 10400 deemed-to-satisfy masonry wall provisions and loading code

South Africa has a housing shortage estimated in excess of 2 million units. This backlog is being addressed predominantly with the construction of 40 m2 low-income, single-storey, detached, state-subsidised houses built with conventional concrete masonry units, regulated by the Application of the National Building Regulations, SANS 10400. However, several developments warrant a reconsideration of SANS 10400 deemed-to-satisfy masonry wall provisions. Two critical configurations of single-storey, unreinforced, bonded masonry walls are generated, based on these deemed-to-satisfy provisions. Subsequently, a simplified micro-scale finite element model is used to analyse these configurations under serviceability and ultimate limit state loading conditions. Characterisation tests of the concrete masonry material, together with numerical fitting to test data and data taken from literature, generate the necessary parametric input. The numerical analyses reveal that in half of the load cases, the walls' resistances failed to achieve the design load as required by the South African loading code. A significant shortfall was found for the out-of-plane resistance against the wind load, as well as structural vulnerability under seismic loading due to the geometric layout permitted by the deemed-to-satisfy rules. This indicates that the SANS 10400 provisions for masonry wall panel geometries require reconsideration, especially given the recent revision of the South African loading code.

Bakteriyel vajinosis (BV) puberte dönemindeki kadınlarda en sık görülen alt genital sistem yakınmasıdır. Vajendeki ekosistemin bozulması sonucu koruyucu laktobasillerin azalması ve anaerob bakteri sayısının aşırı derecede artması sonucu ortaya çıkar.
Bu çalışmada asemptomatik 40 kadından alınan vajinal (VSÖ) ve rektal sürüntü örnekleri (RSÖ) laktobasil insidansı ve türlerinin dağılımını tespit için sellektif kültür yöntemleri kullanılarak değerlendirilmiştir. Ayrıca laktobasillerin karekterizasyonunda fenotipik yöntemlerin yanı sıra sekans bazlı RAPD-PCR yöntemi denenmiştir.
Çalışmaya dahil edilen kadınların Ison & Hay kriterlerine göre değerlendirilmesi sonucu 5 (%15)’inin asemptomatik BV bulgularına sahip oldukları görülmüştür. Kadınların vajen ve rektum sürüntü örneklerinden 132 farklı bakteri kolonisi laktobasil şüpheli bulunmuş, kristal yöntemi ile bunlardan 111’inin 11 farklı türe ait laktobasil olduğu, RAPD-PCR ile yapılan tiplendirmede ise sadece 101’inin 9 farklı tür laktobasil olduğu tespit edilmiştir. RAPD-PCR sonucları baz alındığında 28 (%70) kadında vajen, 31 (%77.5) kadında da rektal sürüntü örneklerinde en az bir laktobasil türünün kolonize olduğu, vajen de en sık kolonize olan türün 10 izolat (%21) ile L. gasseri olduğu, bu türün rektumdan 2. sıklıkta izole edilen tür olup kadınların 6’sında (%29.8) hem vajen hem de rektum örneklerinde kolonize olduğu görülmüştür.
Sonuç olarak, vajen ve rektumunda kolonize olan laktobasil türleri arasında yüksek oranda benzerlik olduğu görülmüş, olup vajene kolonize olan laktobasillerin rektum kökenli oldukları çalışmayı desteklenmiştir.

Objective: Fibroadenoma is the most common benign breast tumor but there are a few studies in the literature that describe the histological features of inner and adjacent tissues of fibroadenomas. The aim of the present study is to examine the histological features of the epithelial and stromal tissues within and around fibroadenomas.
Materials and Metods: In this study, 52 patients with histopathologically diagnosed fibroadenoma from excisional breast biopsy were retrospectively screened and all hematoxylin eosin stained slides were reevaluated by two pathologists. All data were analyzed with SPSS v.21.0 software package.
Results: A statistically significant correlation was detected between complex fibroadenoma and usual ductal hyperplasia (p <0.001), usual ductal hyperplasia was present in 55.9 % of the complex fibroadenomas. No significant association was detected between presence of usual ductal hyperplasia in the surrounding parenchyma and fibroadenoma (p= 0.132). In 26.3 % of fibroadenomas containing usual ductal hyperplasia, usual ductal hyperplasia was present in the adjacent breast parenchyma. There was no significant correlation between complex fibroadenoma and usual ductal hyperplasia or fibrocystic changes in the surrounding parenchyma (p= 0.438 and p= 0.523, respectively).
Conclusion: The rates of the proliferative changes that create a risk for breast cancer in and around the fibroadenoma in the younger ages were found similar with the older ages. The examination of the complex and proliferative changes in the fibroadenoma and the proliferative changes in the surrounding breast parenchyma meticulously and specification of all those changes in the report will allow determination of the risk for development of breast cancer more accurately.
