[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.]

[Not all young, athletic university students have optimal blood pressure. Results of the May 2019 Measurement Month (MMM19)]

PATÓ Anna, NÉMETH Zoltán, JÁRAI Zoltán, KOLLER Ákos

[For about 100 years, it has been known that persistently high blood pressure (hypertension) is the leading cause of cardiovascular disease deaths, such as major risk factors for heart failure, myocardial infarction, stroke, kidney and eye disease. Unfortunately, one of the characteristics of hypertension is that it remains undetected for a long time until damage to one or more organs has already occurred. Therefore, it is very important that systemic blood pressure is monitored from time to time, especially above 45 years of age. The prevalence of hypertension is more than 35% in the Hungarian population. Recent data have pointed out that hypertension may occur at a younger age, although at a lower frequency. Our studies were conducted in the context of the May 2019 Measurement Month (MMM19), an international campaign that draws attention to hypertension and the lack of systematic screening at population level. We hypothesized that hypertension may occur in young, apparently healthy university students. The studies were conducted among students of the University of Physical Education (n = 33; 25 males, 8 females). The mean age was 24.3 years (20–34 years). To measure blood pressure, an automatic blood pressure monitor (Omron MIT5) was used, placed on individuals’ upper arms, as specified in the guidelines, in a relaxed, sitting position. The measurements were repeated three times at one-minute intervals and the average of the three measurements was statistically analyzed. Blood pressure values (mean ± SEM, averaged over 3 measurements) in the student population were systolic 121.9 ± 14.4 mmHg, diastolic 75.1 ± 9.1 mmHg, mean 90.7 ± 10.9 mmHg, and heart rate: 46.8 ± 5.3 mmHg. Although mean blood pressure was within the normal range, higher values were also found in some individuals. Systolic blood pressure fell by 33% due to elevated normal blood pressure, respectively of Grade 1 hypertension. These data confirmed our hypothesis that hypertension may occur at a young age, despite the fact that members of the study population exercise regularly, which is an important preventive factor in the development of cardiovascular disease. These results underscore the importance of regular blood pressure measurement in adolescents, which may reduce the global spread of hypertension and prevent the development of a number of cardiovascular diseases, including stroke, heart attack, renal failure and mental decline.]

[Objective measurement of manual dexterity of Parkinson patients operated with DBS]

SZÁNTÓ Ildikó, SÁNDOR Balázs, KATONA Krisztián, NAGY Máté, JUHÁSZ Annamária, BALÁS István

[The evaluation of hand dexterity is an important marker for the success of DBS (deep brain stimulation) operation in patients with Parkinson’s disease. In this study we applied a simple, semiquantitative optical dental plaque staining technique for the evaluation of the hand dexterity. Ten patient with Parkinson’s disease were involved in the study. After dental students aided tooth brushing, bacterial dental deposits (plaque) were stained then photographed, and quantified under standard conditions before and after DBS surgery. Our results showed a significant decrease in dental plaque deposits after DBS operation. This simple technique seems to be a routinely applicable marker for the evaluation of the hand dexterity. Our future plans is repeating the previous experiement on a higher number of cases.]

[The propagation and semiology of focal epileptic seizures. case presentations to the insula. theoretical considerations]

BALOGH Attila, BALOGH Attila ifj.

[Study objectives – The developing of diagnostical examinations in epileptology provides new challenges in seizure semiology. On the analysis of seizures it is important to examine the mechanisms of their propagation. The brain connectivity (based on the neuroimaging), the shadowing of the movement of excessive neuronal activity (based on computerized EEG and MEG methods), the cognition of the physiological and pathological brain networks are the foot- stone of the epileptic seizure propagation. The investigators prove, by means of case demonstrations of the role of the network nodes and the role of the epileptic hubs in the seizure symptomatology. Methods – The preoperative, intra and postoperative data are analised of three insular and one parietal epileptic patients in point of view of their seizure symptomes. Complex neuroimaging, noninvasive and invasive electrophysiology, intensive long-term video-EEG monitoring, computerized EEG analysis, fuctional mapping, intraoperative corticography were used. The etiology were confirmed with hystology. Results – It is observed that on seizure semiology our patients plays the insula a double role. In some cases, it is the focus of insular seizures with their symptoms difficult to identify. However, in the majority of cases and as a consequence of its rich neural connections, the insula has a peculiar property in the evolution of the symptomatogenic features of seizures. This observations are developing new relationships between the mechanism of seizure propagation and its semiological consequences. Conclusions – On epileptological point of view there are brain structures which has peculiar role in the „designe” of propagation of the epileptic excitement. The numerous new methods in neuroimaging and neurophysiology allowed the connectomical examination of the epileptic networks. The role of the epileptic diathesis is approachable with the metholdology of the brain connectivity. Theoretically the node of the epileptic network consist of the potential pathes where the localised excessive excitement can propagete. The route where the actual seizure can go adhead is determined by the actual edpileptic propensity of the above mentioned potential pathes.]

ARANYNÉ Molnár Tímea, SZABÓ Kinga, RÁZSÓ Katalin, DOMJÁN Andrea, SZŰCS Mónika, SURÁNYI Andrea, BÓDIS József

[Aim: In our study we analysed an alternative training method alone or in combination with pelvic floor muscle (PFM) with deep abdominal muscle strengthen the PFM better. Material and Methods: The study was conducted on women (n=5, mean age ±SD: 51,8 years, ±9,23 years). The Callanetics® gymnastics consisted of training sessions of 2x1 hours (10 weeks only Callanetics® exercises, 10 weeks in combined with PFM contractions). The subjects completed a questionnaire (risk factors, symptoms) and to measure the body parts’ circumference at 0. and 20. weeks. The measurement of the conditional capacitance of the PFM was performed by EMG before the gymnastics, then at weeks 10 and 20. We used R Statistics Software. Results: Significant decreseing were observed in the circumference of extremities and on isometric contraction improves (p=0.036). The dynamic strength showed an increasing tendency. Conclusion: The alternative training method significantly increased the maximum contractions of the PFM.]

[New perspectives in the treatment of lung cancer]

SZONDY Klára, BOGOS Krisztina

[In recent years, huge research is going on in the fi eld of oncology and as a result, we can see a signifi cantly longer survival in this area of medicine. Lung cancer, which has been taken places in the back for decades, it has not become a curable disease, but begins to belong to the chronic diseases. As a result of brilliant surgical technics and stereotactic radiotherapy, or as a result of changes in drug treatment, 5-year survival is not uncommon in metastatic lung cancer patients, next to relatively long progression free survive. After the third-generation cytotoxic combinations the added growth inhibition (VEGF inhibitor) maintenance therapy or continuous pemetrexed cytotoxic chemotherapy were resulted in high survival benefi ts. The fi rst real breakthrough, long progression-free survival was achieved by targeted treatment, which proved to be effective with known driver mutations. The other great result, especially in squamous cell carcinoma, was the immunotherapy, the inhibition of immune checkpoints, which effi cacy was confi rmed in adenocarcinoma also. Several studies are going on with adjuvant or neoadjuvant immunotherapy, and combined use of immunotherapy (either in combination with radiotherapy or cytotoxic chemotherapy).]

[The adverse effects of smoking on our respiratory system based on data of the Hungarian Public Health Screening 2010-2018 ]

KÉKES Ede, DAIKI Tenno, DANKOVICS Gergely, BARNA István

[The regular smoking with or without clinical symptoms causes structural changes in the lung tissue and this is reflected in res­pi­ratory function tests. During the last 9 years of Hungary's comprehesive health promotion screening (MÁESZ) between 2010 and 2018, spiro­metric examinations (PEF, FEV1, MEF25-75, FVC) were performed on 70822 women and 60187 men. We used the percentage of predictive values in the analysis to describe the deviation from normal. The carbon monoxide (eCO) content measurement of the exhaled air (in ppm) was performed on 24899 women and 22340 men. The COPD Evaluation Ques­tionnaire (CAT) was completed by 4166 wo­men and 3170 men. All four parameters of spirometry showed lower values for smokers in both sexes, but in men they were lower than in women. Ageing lowered significantly the values. The rate of changes from normal predictive values and the difference between smokers and non-smokers was the highest for MEF25-75 and FVC. The expiratory CO content (eCO) was significantly higher in smokers than in non-smokers in all age groups. In smokers, the incidence in percent of abnormal CAT score was significantly higher. Respiratory screening tests reveal the harmful effects of smoking, even without clinical symptoms, and indicate the risk of developing COPD.]

[Experiences with the Hungarian version of the Sexual Risk Behavior Beliefs and Self-efficacy Scales ]

EÖRSI Dániel, CZEGLÉDI Edit

[INTRODUCTION - One of the most em­phasized areas of school health education is sexual safety. For risk reduction, adolescent’s beliefs and self-efficacy about sexual safety are decisive; however, no Hungarian measurement tool for this construction was available before. The aims of the present study were to adapt the Sexual Risk Behavior Beliefs and Self-efficacy Scales (SRBBS) to Hungarian, to explore the gender differences, and to assess predictors of condom use among high school students. METHOD - 9th and 10th class high school students in a north-Hungarian city were involved in our cross-sectional study (N = 649; 52.5% boys; mean age: 16.7 years; SD = 1.01 years). Measures: SRBBS questionnaire, sexual behavior issues. RESULTS - The psychometric analysis of SRBBS has yielded encouraging results. The theoretical factor structure is largely supported, the internal consistency of the scales is adequate and its test-retest reliability is mostly acceptable. 35.5% of the participants had sexual intercourse during their lifetime and 65.8% had used condoms at the last occasion. The boys (OR = 2.17, p = 0.021) and those who had more positive attitude towards condom use (OR = 1.24, p = 0.002) were significantly more likely to use a condom during the last act than girls, and subjects with less favorable attitude towards condom use. CONCLUSIONS - SRBBS questionnaire should be introduced into domestic research to measure the effectiveness of health check-ups and school health education programs. ]

[What may hurt the patient’s leg? Lower extremity ischaemia]

FENDRIK Krisztina, BIRÓ Katalin, KOLTAI Katalin, ENDREI Dóra, TÓTH Kálmán, KÉSMÁRKY Gábor

[Peripheral artery disease (PAD) is of high prevalence, and one of the most common clinical manifestations of the atherosclerosis beside ischaemic heart disease and cerebrovascular disease. PAD should be considered as a systemic disease, PAD patients have two times higher ten-year cardiovascular mortality than the normal population. For these reasons, the early recognition of the disease, the appropriate secondary preventive medical and non-medical therapy are of great importance. Risk stratification, proper physical examination, ankle pressure, ankle-brachial index, toe pressure, transcutaneous partial tissue oxygen pressure measurement and duplex ultrasound are the cornerstones to an early diagnosis. This summary aims at calling attention to the fact that lower extremity pain can not only be caused by musculo­sceletal diseases but limb and/or life-threatening limb ischaemia can be revealed in the background. ]

[Hungarian Hypertension Registry. Different methods and effects of increasing physician-patient cooperation on target blood pressure]

SZEGEDI János, KÉKES Ede, KISS István

[The life expectancy, the mortality and the development of complications of hypertensive patients are fundamentally influenced by the treatment, the effectiveness of care and physician-patient cooperation, the achievement of target blood pressure. Based on the database of the Hungarian Hypertonia Registry, we present three examples of the effect of different solutions for physician-patient cooperation on increasing the blood pressure target. During the two years between 2005 and 2007, we used a complex, versatile method of increasing the patient’s adherence in treated hypertensive patients (17,114 males and 21,772 women), with information, education, home-blood pressure diary, and continuous, regular physician- patient communication (sms, green phone line, website). The target blood pressure was significantly increased from 38.8% to 43.9%, and the rate of growth was higher in women. The increase was also significant in the elderly (over 70 years). In the first quarter of 2011, we launched a wide-ranging education and patient support campaign for 28,018 hypertensive patients under the ‘Everywhere Good, Best Home!’ subprogram for promoting of home blood pressure measurement and its use in therapy. 81.3% of the patients had completed the diaries under ther observation period, the full completion of the diaries was 91.3%. At the end of the third month, the target blood pressure of 135/85 mmHg for HBPM increased from baseline 21.2% to 48.8%. Growth was significant (P <0.001). In the year 2015-2016 we started a one-year, multicentric, prospective, observational study, in which 7735 patients aged 18-64 years were included from the database of Hungarian Hypertension Registry. In the non-active group (3313 people), treated hypertensive patients were controlled according to the traditional care program so far, while the active group members (4422) participated in an intensive care program with telemedicine (smart phone application) and other helping opportunities. The control was done at the end of 3, 6, 9, and 12 months after the start. In the active group, blood pressure dier was done by smart phone and every month, in the non-active group, paper logging was done every 3 months. In the active group, the blood pressure dieries were filled with smart phone every month and in nonactive group the paper dieries only every 3 months. Patient adherence was high in both groups (around 70%) and in the active group was greater than in the nonactive group. Target blood pressure (<140/90 mmHg) in the active group increased from 53.8% to 73.4% and in the non-active group from 49.9% to 68.1%. Studies have shown that patient interaction is determined by good communication between the care team and the patient, success of home blood pressure monitoring. The communicative ability of the care team (physician-nurse pharmacist) greatly influences the achievement of the therapeutic target. Modern telecommunications is another useful option.]
