[Diabetes mellitus and cancer risk]

BECHER Péter, PATAI Árpád, MÁJER Katalin

[In the past decades, the prevention of micro- and macrovascular complications has been the main target of diabetes treatment. On the basis of the latest publications that have created a storm we have to highlight the associations between diabetes mellitus, its treatment protocols and tumours. Analysing the often controversial human results, in the absence of relevant prospective studies, we have to consider preclinical observations to choose a safe treatment method.]

[The significance of statin pleiotropy]

KOLOSSVÁRY Endre

[Application of statins in the primary and secondary prevention of atherosclerosis is of great importance. Attenuation of cardiovascular risk by statin therapy is primarily related to a decrease in serum cholesterol levels. Scientific data published in the past few years highlight the importance of the beneficial effects of statins that are not related to cholesterol-lowering. These effects are known as pleiotropic effects. This review aims to present the current view of statins’ pleiotropic effects.]

[New findings in the cortical bone biology and its role in bone fractures]

BALOGH Ádám, BHATTOA Harjit Pál

[The authors surveyed the already known factors responsible for the osteoporotic bone fragility. Then the results of using modern imaging techniques (micro-CT, high-resolution peripheral computed quantitative tomograph - HR-pQCT) and advanced computer analytic methods (finite element analysis, FEA) are presented. These data - beyond the already known fracture risk factors (age, risk of falling, bone mineral density - BMD, and fine structure damage of trabecular bone) are stressing the importance of the (micro)damage of cortical bone as a fracture risk factor, which has been still underrated. The cortical thickening and increased porosity - verified on various population samples - are increasing the risk of fractures in certain subgroups of subjects having identical BMD values, even among those, who are considered only osteopenic by the earlier classification based on BMD values. Backed with modern software batteries, the new imaging techniques are expected to enter clinical application in the near future. Pharmacologic agents with stronger cortical effect are already available and research is continuing to find new drugs to use in the management of osteoporotic patients of high fracture risk.]

[X-ray examination of paintings]

SZABÓ Éva, SZENTKIRÁLYI Miklós

[INTRODUCTION - After the discovery of X-ray it was not only used for medical purposes, but also to study the internal structure of various objects. The X-ray examination can be applied not only to examine paintings, but other works of art. METHODS AND RESULTS - The rontgenograms are made by industrial film without any screen in the museum. In case of paintings soft-beam examination technique was used. The basic principle of the X-ray examination of different paintings is based on the presence of different atomic number in different paints. Authors after the examination of four paintings achieved a significant finding. In these paintings the stylistic and structural features of the pictures, injuries, originality, changes in the composition during the work of the artist can be studied. CONCLUSIONS - Recordings made by an industrial radiological equipment in the Museum of Fine Arts (Budapest) are helpful in the restorer work.]

[Liquid biopsy in clinical oncology – fine-tuning precision medicine]

[The classical method of genetically characterising a tumour requires tissue biopsy with which a small sample is removed from the affected organ. This sample represents the tumour in the further analyses. However, the localised nature of sample collection limits representative characterisation. The so-called circulating tumour DNA, isolated from blood plasma after a simple sample collection, potentially enables the oncological analysis of all tumour tissues carrying genetic alterations that can be identifi ed as markers. In order to maximally exploit the potentials of circulating tumour DNA, we must adjust the analytical tools to its specifi c features. The preanalytical handling and storage of the sample signifi cantly infl uences its further usability. In order to be able to detect a potential mutation in a mostly wild-type background, the development of new, specifi c methods is needed, most of which are based on next-generation sequencing techniques. In the past decades, the pronounced decrease in the costs of such techniques led to an accumulation of an immense amount of genetic information on tumorigenesis. Due to the development of sequencing technologies, the turnaround times of tests also decreased enabling their employment in routine care besides research. Starting from our research, this can be realised via three approaches: technological development, the implementation of our already existing diagnostic methods in liquid biopsy, and the construction of well-planned disease-specifi c gene panels. Based on international trends and our experience in serum diagnostics, we are certain that liquid biopsy will become a central pillar of oncological screening and precision oncology in the near future.]
