[Digitally-assisted treatment planning in precision oncology]

PETÁK István, VÁLYI-NAGY István

[The progress of molecular information based on personalized precision medicine has reached a new milestone. Actually, about 6 million mutations of 600 genes may be related to the development of cancer, and on average, 3-4 of these “driver” mutations are present in each patient. Due to the progress in molecular diagnostics, we can now routinely identify the molecular profile of tumors in clinical settings. By clinical translation, there are actually available more than 125 targeted pharmaceuticals and hundreds of such therapies are under clinical trial. As a result, we have many first-line and licenced treatment options to be elected by molecular information as the optimal one for every patient. There is an increasing need for complex informatics solutions by medical software. Geneticists, molecular biologists, molecular pathologists, molecular pharmacologists are already using bioinformatics and interpretation software on their daily work. Today, online digital tools of artificial intelligence are also available for physicians for assisted treatment planning. Telemedicine, videoconferencing provide solutions for interdisciplinary virtual molecular tumor boards, which democratizes the access to precision oncology for all doctors and patients. ]

[Metals and cancer]

VETLÉNYI Enikő, RÁCZ Gergely

[We often tend to forget about our environment when looking for the origin of a disease. Inhaled air, drinking water and food, substances in contact with the skin all have an effect on the human body. Metals are indispensable parts of our everyday lives, their mining, processing and use cause a continuous exposure to them. Metal exert their effects on the body in various ways. Many of them are essential for maintaining homeostasis, but excessive or harmful metal intake can lead to health damage, including tumour formation through multiple attack points. Metals substitute each other during different transport processes and in the structure of proteins, they cause oxidative stress and bind to DNA, thereby damaging it. Applying them appropriately, the proapoptotic effect of the metal compounds is brought to the fore, thus becoming a therapeutic tool for tumours. Nowadays, platinum(II) compounds are widely used as chemotherapeutic agents and there are many ongoing studies to fi nd metal compounds with an ideal therapeutic and side-effect profi le. The aims of this article were to draw the attention to the dangers of metals in relation to cancer and to highlight their diverse application possibilities in current and future cancer therapy and diagnostics.]

[Role of Atrial Fibrillation in Stroke Prevalence: Implementation of CHA2DS2 – Vasc Risk Stratifi­cation Scale]

PAPP László, VIDA Nóra, BENGŐ Szilvia, KIS Tamás , GAÁL Gabriella, PETŐ Zsófia

[Introduction: Stroke is one of the leading causes of death and disability, therefore is an important public health concern. 20% of ischaemic cerebrovascular diseases are casued by cardiac-related embolism, wiith non-valvular atrial fibrillation (AF) as a major cause, and results in approximately 3-5-fold risk improvement. The aim of this study is to introduce the CHADS2-VASc scoring system, as an important tool in the estimation of stroke risk in AF patients. Recognition of AF and initiation of adequate therapy is a crucial step in the prevention of serious complications. The best-known indexes for AF’s vascular effects are HAS-BLED and CHADS2-VASc. According to European Society of Cardiology, CHADS2-VASc is recommended to use in every AF case with stroke risk, when direct anticoagulant therapy could be implemented. A nurse can work on stroke risk reduction among AF patients in various levels and competences. Primary prevention and health promotion is a responsibility for every health care worker, but at the same time, Advenced Practice Nurse could have a role either in diagnostics or initiating proper therapy.]

[The role of MR angiography in the examination of intracranial aneurysms: A comparative study]

P. Nagy Zoltán, BAJZIK Gábor , BOGNER Péter, BERÉNYI Ervin, SZÁSZ Krisztina, KOPA János, REPA Imre

[MR imaging has recently emerged for visual representation of blood vessel structures as well. With MR angiography (MRA), appropriate diagnosis can be established for a number of pathologies involving the arteries and veins. In this report, authors analyse the significance of MR and MRA examinations in the diagnostics of intracranial aneurysms of 87 cases, comparing these procedures with results obtained by digital subtraction angiography (DSA), which is regarded as the gold standard method. In 52 patients where surgical intervention was performed, intraoperative findings were used as control. MR - MR angiographic examination was very sensitive in detecting aneurysms larger than 3 mm (98%), the rate of depicting smaller aneurysms proved to be lower (56%), the overall sensitivity was 79%. MRA is an excellent non invasive diagnostic tool in the examination of intracranial aneurysms. The method can not replace catheter angiography completely but its application is justified and useful in many cases. Occasionally, aneurysms not seen on DSA can be depicted with MR angiography. ]

[Metabolic syndrome - metabolic risk factors]

AUDIKOVSZKY Mária, PADOS Gyula

[Since abdominal type obesity, diabetes mellitus and the metabolic syndrome were classified as primary coronary risk factors beside hypercholesterolaemia and smoking, five out of six of the most significant risk factors are regarded of metabolic origin. Simultaneous occurrence of these factors are far more frequent in the population. The composition and background of this syndrome were subject of numerous analyses and classification from syndrome-X to metabolic syndrome. Reaven finds insulin resistance and compensatory hyperinsulinism as the primary cause, while Matsuzava et al regards visceral type obesity (visceral fat syndrome), and Björntrop views the increase in sympathetic tone (civilization syndrome) as fundamental. In the diagnostics and therapy of the metabolic syndrome we should consider all factors mentioned above. We have to establish the presence of three or more classic risk factors for a firm diagnosis. In the therapy, decreasing the body weight with diet and exercise is crucial, with adjuvant drug therapy of antidiabetics, insulinsensitizers, lipid lowering agents and antihypertensives, as needed. ]

[Newly discovered molecules the chemokines]

KŐHIDAI László, DÉRFALVY Beáta

[Chemokine research in the last decade has provided new results in several areas of biomedicine. Investigation and characterization of chemokines resulted in better understanding and modeling complex pathophysiological and immunological processes. Chemokine research opened up entirely new aspects on the defense against pathogenic agents as well as on the processes of inflammation and angiogenesis. With the amount of clinical data growing steadily, it is clear that chemokines could play very important role not only in solving the problems of the oretical and experimental biology but also with their application in clinical diagnostics and therapy. ]

[The role of APN in the Care of Patients with High Blood Pressure]

VÖRÖS Tünde, PAKAI Annamária, SZEBENI-KOVÁCS Gyula, SZABÓNÉ Bálint Ágnes, OLÁH András

[Internationally the role of Advanced Practice Nurses (APN) has grown a lot in the treatment for high blood pressure. The tasks of Advanced Practice Nurses with an advanced degree include the observation, following, diagnostics, medicinal treatment, health education, education of patients, coordination of care, checking of performance and improvement of quality. In Hungary the family doctors do the care of people with hypertonia in the primary care. Because of the number of patients who must be treated every day comes less time per capita in the care. For a high number of acute patients must be cared and for this reason less time remains for the care of chronic patients. In Hungary the education for Advanced Practice Nurse (APN) with an advanced degree has started in autumn 2017. The first of these nurses will get out of the education in February 2019. Due to their education they will be able to care acute illnesses in practices of family doctors and in communities of practice. Besides they will be able to explore, care and follow chronic patients. ]

[Molecular residual tumor monitoring in solid cancers]

SZÁSZ A. Marcell, TOBIÁS Bálint, KÓSA János, LAKATOS Péter

[Blood-based diagnostics has long been used in the oncological practice of solid tumors, but its full potential is just unfolding recently. Quantitative measurement of tumor markers, circulating tumor cells, and some of their products or components have now become available and are part of a multimodal system that provides additive parameters in clinical decision making. The most challenging oncological questions can be answered by the detection, characterization and measurement of circulating free DNA (cfDNA), which, due to its growing importance, bears the potential of incorporation into routine practice. In this overview, we review the „blood impressions” of solid tumors and present the most promising results in different patient groups, especially in lung, breast, colon, and bladder tumors, which are also valid for other solid tumors.]
