Objectives – Stroke is the third leading cause of death in the European region. In spite of a decreasing trend, stroke related mortality remains higher in Hungary and Romania when compared to the EU average. This might be due to higher incidence, increased severity or even less effective care. Methods – In this study we used two large, hospital based databases from Targu Mures (Romania) and Debrecen (Hungary) to compare not only the demographic characteristics of stroke patients from these countries but also the risk factors, as well as stroke severity and short term outcome. Results – The gender related distribution of patients was similar to those found in the European Survey, whereas the mean age of patients at stroke onset was similar in the two countries but lower by four years. Although the length of hospital stay was significantly different in the two countries it was still much shorter (about half) than in most reports from western European countries. The overall fatality rate in both databases, regardless of gender was comparable to averages from Europe and other countries. In both countries we found a high number of risk factors, frequently overlapping. The prevalence of risk factors (hypertension, smoking, hyperlipidaemia) was higher than those reported in other countries, which can explain the high ratio of recurring stroke. Discussion – In summary, the comparatively analyzed data from the two large databases showed several similarities, especially regarding the high number of modifiable risk factors, and as such further effort is needed regarding primary prevention.

DUKAY-SZABÓ Szilvia, SIMON Dávid, VARGA Márta, SZABÓ Pál, TÚRY Ferenc, RATHNER Günther

[Aim - Eating disorders are becoming an increasingly relevant health issue, therefore the fast and accurate screening of people at risk is of great practical importance. The aim of SCOFF questionnaire is to assess this risk and the extent to which a person is affected, by using five simple yes or no questions. The objective of our study was to assess the validity of the Hungarian version of the test Methods - 777 medical students (210 men, 567 women, mean age 22.3±2.33 years) participated in the survey. The online questionnaire contained anthropometric data, the Eating Behaviour Severity Scale and, beside the SCOFF, the Eating Disorder Inventory (EDI). Results - The SCOFF is excellent at screening clinical eating disorders. Its sensitivity was 100% and specificity 85.1%. It is less efficient at detecting subclinical cases, but it does not show worse results than EDI. According to the data SCOFF is better at identifying more serious cases. Applying on the same sample SCOFF had higher sensitivity and lower specificity than EDI. Discussion - SCOFF is suitable for primary screening of eating disorders with a non-diagnostic purpose, taken two “yes” answers out of five as the critical margin, specified by the authors.]

[Cardiovascular risk assessment in chronic kidney disease, significance of left ventricular myocardial mass index]

SÁGI Balázs, KÉSŐI István, VAS Tibor, CSIKY Botond, NAGY Judit, KOVÁCS Tibor

[Introduction: Earlier studies have shown that cardiovascular (CV) mortality and morbidity in chronic kidney disease (CKD) often exceed their average population, and left ventricular hypertrophy (LVH) is an independent risk factor for CV disease. However, in CKD, the relationship between LVH, arterial stiffness (AS) and renal function has not yet been fully elucidated. Little data is available on their prognostic role. Aims of our study a) cross-sectional examination of the relationship between left ventricular mass index (LVMI), arterial vascular stiffness, and renal function, b) in our follow-up study, clarification of the LVMI, the prognostic role of AS in patients with CKD, IgA nephropathy (IgAN). Methods: In our cross-sectional study, 79 IgAN patients were examined in our clinic. The myocardial mass index (LVMI) was determined using an estimation formula after echocardiographic measurements. Arterial stiffness was measured using a photoplethizmography technique (PulseTrace) and characterized by the stiffness index (SI). The MDRD formula was used to estimate renal function (GFR) (eGFR, ml/min/1.73 m2). In the prognostic study the primary combined endpoint was total mortality, the most important CV events (stroke, myocardial infarction or cardiovascular interventions such as revascularization) and end stage renal disease. Secondary endpoints were CV and renal endpoints separately. Results: Of the 79 patients included in our cross-sectional study, 50 were men, with an average age of 46 ± 11 years. The mean value of LVMI was 106.66 ± 22.98 g/m2. Patients were divided into groups of 115 g/m2 for males considered to be abnormal and 95 g/m2 for women. LVMI is closely correlated with SI and inversely with eGFR (corr. coeff: 0.358; p <0.05 or -0.526; p <0.001). In case of LVH, SI was significantly higher in both sexes (p = 0.005 in males, p = 0.04 in females). In case of higher LVMI, renal function was significantly lower (p = 0.002 in males, p = 0.01 in females). Metabolic syndrome occurred in several cases in both sexes with LVH, but the difference was only significant in male patients (males 6 vs. 10, p = 0.008; females 2 vs. 4, p = 0.29). In our follow-up study, the presence of LVH in men significantly reduced survival in both primary and secondary endpoints, whereas in women there was no significant difference. Conclusion: In IgAN decreasing of renal function is closely related to left ventricular hypertrophy and vascular stiffness, as well as a close relationship was found between LVMI and AS. Reduced renal function is associated with an increase in LVMI and an increase in AS, which may result in a worse prognosis for both CV and renal outcomes. The underlying role of all these can be assumed to be a common vascular and myocardial pathological remodeling.]

[About general practitioners in Hungary - without political roadblocks]

BALÁZS Péter

[A brief introduction about the primary care’s evolution is rather improving the clear sight since it supports our right judgement and helps to draw right consequences. Thus, we are able to realise more precisely our strategic aims, actual domestic problems, and the forced pathways indicated by the prevailing trends and the action radius of our reform endeavours. The present study shows hidden risks encoded in human resources, specialists’ services and shed light into the grey zone of remuneration. Indeed, the trends are alarming, the spaces are narrow for actions nevertheless we can escape our century old legacy by innovative solutions. While re-thinking totally the whole system nevertheless maintaining all immanent principles we can just in the short run revitalise our ailing primary health care. ]

[Recommendations of the European Atherosclerosis Society (EAS) and the European Society of Cardiology (ESC) for dyslipidaemia. Focused on: primary prevention]

BAJNOK László

[In 2019 the European Atherosclerosis So­ciety (EAS) and European Society of Car­dio­logy (ESC) renewed their dyslipidae­mia guidelines. The new version is more progressive than the previous ones. Thus, in the low-risk, not severely hy­per­choles­te­ro­lae­mic population cholesterol-lowering medication is also suggested. Except this low-risk group, atherogenic target values, e.g. for LDL-cholesterol, were reduced by an entire category, in some cases to the lowest one. If these goals cannot be achieved with statin-monotherapy, combined treatment is recommended generally by the cholesterol inhibitor ezetimib, and in some very high-risk cases also by innovative cholesterol lowering so-called PCSK9 inhibitor. ]

TORZSA Péter, KALABAY László, CSATLÓS Dalma, HARGITTAY Csenge, MÁRKUS Bernadett, MOHOS András, SZIGETI Mátyás, FERENCI Tamás, MARJOLEIN Verschoor, ROZSNYAI Zsofia, JACOBIJN Gussekloo, ROSALINDE K. E. Poortvliet, SVEN Streit

[BACKGROUND - When treating very el­der­ly and frail hypertensive patients, there have to be taken in account the general health condition and frailty of patients, the present cardiovascular diseases (CVD) and values of the systolic blood pressure (SBP). Goals - In a clinical study performed in 29 countries, we aimed to analyse differences in practical antihypertensive therapy of family doctors among patients older than 80 years; further we sought to answer how much was influenced their therapeutic choice by frailty of the old age. The other goal of our study was to compare Hungarian versus international outcomes. Methodology - As part of an online survey, family practitioners had to decide about necessity of starting antihypertensive treatment among very elderly patients according to different patterns of frailty, SBP and CVD. The ratio of specific cases with positive treatment decision of family practitioners was compared in all 29 countries. We used a logistic mixed model analysis to multivariately model the role of frailty. Results - 2543 family practitioners participated in the cross-national study; 52% were female; 51% practised in urban environment. In 61% of practices, there was the ratio higher than 10% of very elderly patients. Hungary participated with 247 family practitioners in the study; 52.3% were female; 63.1% practised in urban environment. In 48.8% of practices the ratio of very elderly patients was higher than 10%. In 24 out of the 29 countries (83%), frailty was associated with GPs’ negative decision about starting treatment even after adjustment for SBP, CVD, and GP characteristics (odds ratio [OR 0.53]), 95% CI: 0.48-0.59; ORs per country 0.11-1.78). The lowest treatment ratio was in the Netherlands (34.2%; 95% CI: 32.0-36.5%) and the highest one in Ukraine (88.3%; 95% CI: 85.3-90.9%). In Hungary’s treatment ratio ranged 50-59%. This country ranked on the 27th place since Hungarian family practitioners chose rather to start antihypertensive treatment despite the frailty of the patient (OR=1.16; 95% CI: 0.85-1.59). Hungarian family practitioners started pharmacotherapy of elderly patients more frequently if they were males (OR= 1.45; 95% CI: 0.81-2.61), were working in their practice for less than 5 years (OR=2.41; 94% CI: 0.51-11.38), and if they had many patients aged over 80 years in their practice (OR=2.18; 95% CI: 0.70-6.80), however these differences were sta­­tistically not significant. Among Hun­ga­rian family practitioners starting therapy was significantly influen­ced by cardiovascular disease (OR=3.71; 95% CI: 2.64-5.23) and a SBP over 160 mmHg (OR=190.39; 95% CI: 106.83-339.28). Conclusions - In our study, there was significant difference between countries in starting antihypertensive treatment for very elderly patients. However, Hungary was among the countries where family practitioners preferred to treat their frail patients. The patients’ frailty did not have any impact on starting the therapy; rather cardiovascular disease and a SBP over 160 mmHg decided. It is an important message of the study that there is continuous need to educate family practitioners and trainees about the treatment of frail, elderly hypertensive patients.]

[Correction of the physiological artefacts at pre-surgical clinical functional MR]

KISS Máté, GÁL Andor Viktor, KOZÁK Lajos Rudolf, MARTOS János, NAGY Zoltán

[Introduction/aim of the study - Pre-surgical functional MRI (fMRI) is an important modality of examinations before brain surgery. There are several artefacts (e.g. motion, susceptibility) which may hinder the evaluation of fMRI data. Physiological artefacts (breathing, pulsation) also affect the sensitivity and specificity of anatomical localization. The aim of this study is to demonstrate the efficiency of physiological artefact identification and removal methods for presurgical evaluation. Materials and methods - Siemens Magnetom Verio 3T MRI scanner was used to collect data. The physiological parameters (breathing, pulse) were recorded with the MRI system’s built-in devices. Data from fourteen patients - with primary brain tumour - were evaluated with SPM12 utilizing the RETROICOR/RVHR tool to detect and decrease the effect of physiological artefacts. We compared the statistical maps obtained with and without the physiological correction using the Jaccard similarity coefficient, and ROI analyses. Results - Significant differences were found in the mean ROI values (p<0.0016) and the extensions of eloquent activations (p<0.0013), when using the physiological correction (RETORICOR/RVHR) based on convolution method. On the other hand, no significant differences were found between the ROIs’ standard deviations (F=0.28). The RETROICOR/ RVHR method helps to define the precise localisation of eloquent areas (p<0.009). The number of irrelevant (non-significant) voxels were increased (p<0.001). Conclusions - Minimising of physiological artefacts in fMRI data calculations, the (RETROICOR/RVHR) method based on convolution has been successfully adapted. This algorithm could be helpful before neurosurgical intervention. The activity pattern became more reliable. ]

[The Veszprém model, alias a different approach of psychiatric care]

BALCZÁR Lajos, ENGLERT Tímea

[This study describes an integration of a county-level psychiatric care unit with two elements of primary social care, namely the community psychiatric care and the daycare for psychiatric patients via mediation of a specific foundation. Adequate trainings make the connection and dual employment possible in the presented system. On the health care side development is characterized by extended psychiatric care with effective psychosocial interventions. Adding specialized group psychotherapies and sociotherapies to the activity of the social care also brought a quality change, extension of which provided self-help and the consumers' applicability as therapy leaders in sociotherapy group. Based on our ten years of practice we may declare that recovery-based psychiatric rehabilitation can be realized more effectively in this community-based biopsychosocial model of care. ]

[Molecular subtypes and the evolution of treatment decisions in metastatic colorectal cancer]

RODRIGO Dienstmann, RAMON Salazar, JOSEP Tabernero

[Colorectal cancer (CRC) has clinically-relevant molecular heterogeneity at multiple levels: genomics, epigenomics, transcriptomics and microenvironment features. Genomic events acquired during carcinogenesis remain drivers of cancer progression in the metastatic setting. For example, KRAS and NRAS mutations defi ne a population refractory to EGFR monoclonal antibodies, BRAFV600E mutations associate with poor outcome under standard therapies and response to targeted inhibitors in combinations, while HER2 amplifi cations confer unique sensitivity to double HER2 blockade. Multiple rare gene alterations driving resistance to EGFR monoclonal antibodies have been described with signifi cant overlap in primary and acquired mechanisms, in line with a clonal selection process. In this context, sequential analysis of circulating tumor DNA has the potential to guide drug development in a treatment refractory setting. Rare kinase fusion events and complex alterations in genes involved in DNA damage repair have been described, with emerging evidence for targetability. On the other hand, transcriptomic subtypes and pathway activation signatures have also shown prognostic and potential predictive value in metastatic CRC. These markers refl ect stromal and immune microenvironment interactions with cancer cells. For example, the microsatellite instable (MSI) or POLE ultramutant CRC population is particularly sensitive to immune checkpoint inhibitors, while tumors with a mesenchymal phenotype are characterized by activation of immunosuppressive molecules that mandate stratifi ed development of novel immunotherapy combinations. In this manuscript we review the expanding landscape of targetable oncogenic alterations and signatures in metastatic CRC and discuss the clinical implementation of novel molecular diagnostic tests.]
