[Analysis of factors influencing the efficacy of Hungarian acute cardiac care]


[Despite the modern invasive acute cardiac care available for all, as opposed to short-term mortality, the long-term mortality of Hungarian myocardial infarction patients exceeds significantly those of European patients getting similar treatment. In order to change this situation, it is necessary to assess and analyse exactly the factors behind. While analysing retrospectively the data of Hungarian acute myocardial infarction patients, we identified the influencing factors of short- and long-term mortality. This study processed data from 2003 to the present days from a number of registries (Heart- and Vascular Center of Semmelweis University VMAJOR I and VMAJOR II registry, Stent for Life I and II Programs of the European Society of Cardiology, National Public Health Service’s registry about Cardiac Care in Central Hungary, Budapest Modell database). According to our detailed examination, the proportion of primary per­cutaneous coronary intervention in ST-segment elevation myocardial infarction is at Western-European level, however the invasive treatment of acute coronary attack patients with Non-ST segment myocardial infarction is below the required. The so-cal­led hesitation span of Hungarian pa­tients with ST-segment myocardial infarc­tion is substantially longer than that of neighbouring countries thus the average cardiovascular risk of relevant Hungarian patients is significantly higher than those of the GRACE Register’s population. Based on our results a complex strategy can be developed which may have impact also on strategic health­care decisions in order to reduce the long-term mortality of patients surviving myocardial infarction.]

[Opportunities and challenges in online support of cancer patients]

B. PAPP László

[The online support of oncological care may increase patients’ adherence, and by this it can contribute to the effectiveness of treatment, the improvement of quality of life and physician-patient communication as well as to a higher sense of control over the disease. With the online support of supportive care, patients and their relatives can get information on what they can do in order to improve their conditions, how they can recognize side effects and alarming symptoms of complications, what kind of changes they need to make in their lifestyle and how they can reduce the level of distress. Though the positive outcomes are feasible in many cases, quite considerable number of reports in the fi eld do not meet the requirements of evidence. The online support of oncological care may offer considerable opportunities, however, it may further increase inequality: the more educated and well-off patients with higher level of health awareness may benefi t more, meanwhile for the ones at the bottom of digital divide, the disadvantages may increase. The Hungarian internet coverage and accessibility make the broader online support technologically possible, however, its effectiveness may be hindered by the lack of human skills. Therefore, it is a real challenge to establish such platforms that can be used by the broadest spectrum of society, they are comprehensible for patients and their relatives with lower education, but also satisfying for patients and their relatives with higher level of literacy and expectations.]

[The role of stress management in the care of hypertension and the treatment of cardiovascular disease]

SOMOGYI Éva, KISS Zoltán, STAUDER Adrienne

[The aim of this paper is to give an overview of the relationship between stress and hypertension and cardiovascular diseases, furthermore to introduce an evidence based stress management intervention available in Hungary. The correlation between cardiovascular disease and psychosocial factors (including concomitant mental disorders as well as personality traits or the effect of social environment) has been established in numerous studies aimed at investigating pathogenesis or various clinical endpoints. The 2016 Guidelines of the European Society of Cardiology include the assessment and the management of psychosocial problems with behavioral medicine interventions as a I.A level recommendation. The implementation of these guidelines in everyday clinical practice is crucial to decrease cardiovascular risk. This involves the training of health care professionals, the facilitation of multidisciplinary collaboration and the integration of behavioral intervention into everyday care. The Williams Life Skills (WLS) program is an evidence based behavioral medicine intervention aiming to improve stress management and communication skills which implemented internationally and also available all over Hungary. It involves the learning of simple coping strategies that facilitate the successful management of every day psychosocial stress situations and the self-conscious reduction of bodily and psychological tensions. In cardiovascular disease, this improves quality of life and survival. The WLS program is especially recommended for healthcare workers to decrease the negative health consequences of their high stress load and to prevent burnout. Stress may affect both doctors and patients during their interactions. Bálint groups have a positive impact on the physician-patient collaboration and help to reduce burnout by improving the understanding of the diseases from a more complex approach.]

[Post-career development of cardiometabolic changes and hypertension in competitive athletes]


[Regular physical activity is essential in delaying the aging processes (e.g. arterial remodelling – stiffening, metabolism, bodyweight), the beneficial effects of competitive sports – especially strength sports – according to the recent data of the literature are questionable. The beneficial effects of physical activity on the cardiovascular (CV) system are well known, however less is known regarding the delayed impacts of high intensity competitive sports on the CV system, especially after the sport career is over. This review summarizes the effects of active competitive sport and the post-career period on the cardiometabolic system with special attention to the systemic blood pressure and the development of metabolic syndrome. After sport career, the welldeveloped high performance cardiovascular- and metabolic system suddenly is much less used, but still supported by sport-level diet. It is well known that hypertension is a significant pathogenic factor in the development of cardiovascular diseases, characterized – among others – by reduced elasticity of large- and medium- sized vessels thereby importantly contributing to the development of systolic hypertension. Inflammation and thrombus formation both play an important role in the development of vascular injury and atherosclerosis. The increased tone of microvessels can impair the blood supply of certain organs, including the coronary circulation. It has been ample shown, that regular non-competitive, aerobic exercise activities are important factors in preventing hypertension. Such pathological changes become more evident after the development of post-career obesity, as well as the development of hypertension due to the activation of the renin-angiotensin system through sodium retention and other metabolic changes (increased glucose tolerance, insulin resistance, type II diabetes mellitus). It has been ample shown, that regular non-competitive, dynamic aerobic exercise activities are important factors in preventing hypertension. The frequency, intensity, type, and time (FITT) principle of exercise prescription is the first and common therapeutic approach, which represents the translation of cardiovascular basic science research results into hypertension treatment, thus can provide a personalized physical activity program/therapy according to medical needs not just for the post-career sportspersons, but the wide range of patients.]

[The pain-trigger role of cytokines in the nervous system – the direct analgesic effect of anti-cytokine therapy ]


[Nociceptive, neuropathic and central me­chanisms are involved in the perception, transmission and processing of chronic pain and shaping of cerebral pain image. Alar­mins – molecules alarming defence and signing the presence of pathogens and tissue damage - trigger a series of pathogenic events resulting in inflammatory pain stimuli. Proinflammatory cytokines play a determining role in the pain perception at the level of the nervous system. Continuous inflammatory stimuli while sensitizing the periferic and central neurons activate the pain-related cerebral areas and develop the complex pain image, the pain matrix. Ce­reb­ral functional connections are operating in networks and can be visualized by functional MRI. Cytokines activate the neurons directly or indirectly by other neuromediators. Cytokine receptors are expressed on no­ciceptors and even on higher-level neurons and on various non-neural cells, such as microglia and astrocytes. The most ubiquitous cytokines are the Tumour Necrosis Factor and Interleukin 6 in the nervous sys­tem. The signaling pathways are the Nuclear Factor κB and the Janus-kinase enzyme system. The proinflammatory cytokines and the Janus-kinase are therefore primary therapeutic targets. Anti-cytokine biologicals and small molecular kinase inhibitors decrease the pain and improve functional activity in rheumatoid arthritis. Decrease of pain was more pronounced than expected only from the decrease of the clinical biomarkers of inflammation. The early and ra­pid painkiller effect of targeted biological and chemical-biological response modifiers is attributed to their direct analgesic effect on the brain.]

[Persisting Hashimoto’s thyroiditis converting to Graves’ disease]


[Graves’disease and Hashimoto’s thyroiditis are the two most important types of autoimmune thyroid dis­eases. Autoimmune hyperthyroidism commonly leads later on to hypothyroidism. The conversion from persisting Hashimoto-thyroiditis to hyperthyroidism is rare in the literature. The author presents the cases of two patients, whose Hashimoto’s thyroiditis treated with thyroxin for years, changed into Graves’ hyperthyroidism sponta­neously. CASE REPORT – The patients had been diagnosed with autoimmune hypothyroidism since several years. The clinical symp­­toms, the low peripheral hormone le­vels, the high level of antithyroid antibo­dies and the ultrasound imaging confirmed the hypertrophic form of Hashimoto’s thy­roiditis. After several years of high dose le­vothyroxin treatment, clinical symptoms of hyperthyroidism have appeared. After omit­ting the substitution, the thyroid hormone levelled off at high values and the level of anti-TSH receptor antibodies raised too. The diffuse, obviously increased blood flow of the thyroid glands, and in one of the patients the thyroid scan, confirmed the Graves’ disease. During the thyreostatic treatment, the symptoms of the patients disappeared, they became euthyreoid and the antibody levels decreased as well. The Graves’ disease and the Hashimoto’s thyroiditis have many common features. These immunological, ge­netic and other common features enable the mutual transition of these two diseases.]

[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.]

[Recurrent inhibition during Jendrassik maneuver]


[Objective – Conflicting theoretical models exist regarding the mechanism related to the ability of the Jendrassik maneuver to reinforce reflex parameters. Our objective was to investigate if vigorous handgrip would induce changes in recurrent inhibition of soleus motoneurons. Method – Soleus H reflex was evoked by stimulating the tibial nerve at rest and during bilateral vigorous handgrip, alternating single (H1) and paired stimulation (H2). At paired stimulation we used interstimulus intervals of 10, 15, 20 and 25 ms and supramaximal test stimulus. H1- and H2-wave amplitudes were expressed as percentage of maximal M-wave amplitude. Conditioned H2 wave maximal (H2max) and minimal (H2) amplitudes evoked at rest and expressed as a percentage of the unconditioned H1max amplitude were compared with the corresponding values obtained during handgrip by means of paired Student test and Bonferroni correction. Subjects – At the study participated 28 healthy volunteers. Results – The H1max/Mmax × 100 values obtained during handgrip (37.5±10.1) were significantly higher than those obtained at rest (27.1±7.4). The H2max/H1max × 100-va­lues obtained at paired stimulation were significantly higher during handgrip than at rest, while no significant diffe­rence was found between the H2/H1max × 100-values obtained during handgrip and at rest respectively. Discussion – The H2max/H1max is determined by both the excitability of the motoneurons and the recurrent inhibition elicited by the conditioning stimulus, while H2/H1max indicates only the level of recurrent inhibition. According to our results the Renshaw cells retain their inhibitory effect on the soleus alpha motoneurons during remote muscle contraction. Conclusion – Soleus H reflex enhancement during Jendrassik maneuver is not due to decrease of recurrent inhibition. ]

[Attachment as a predictor of risk for eating disorders on a representative hungarian adult sample]

SZALAI Dömötör Tamás, CZEGLÉDI Edit

[Background and purpose – Many studies confirm the relationship between attachment disturbances and (the severity of) eating disorders, however among them only one Hungarian study can be found. The exact predisposing traits of attachment and the strength of relationship is still uncleared. Our aim was to explore these aspects. Methods – Study was based on a cross-sectional nationally representative survey, called „Hungarostudy 2013” (N=2000, 46.9% males, mean age 46.9 years, SD=18.24 years). Measures: Sociodemographic and self-reported anthropometric data (weight and height), short Hungarian version of Relationship Scale Questionnaire, SCOFF questionnaire and short Hungarian version of Beck Depression Inventory. Results – The frequency of risk for eating disorders (anorexia or bulimia nervosa) was 3.9% (N=76) among the respondents (N=1860). Attachment anxiety was significantly higher in the risk for eating disorders group (t(1888)=-3.939, p<0.001), and significantly predicted the risk for eating disorders after adjusting for the potential background variables (OR=1.09, p=0.040). Detachment was not a significant predictor of risk for eating disorders (OR=0.98, p=0.515). Younger age (OR=0.97, p<0.001), higher level of depression (OR=1.09, p<0.001) and higher body mass index (OR=1.08, p<0.001) were also significant cross-sectional predictors of risk for eating disorders. The explained variance of the model was 10.7%. Conclusion – The study supported, that higher attachment anxiety is associated with the increased risk of eating disorders, with a possible therapeutic relevance. Assessment of attachment’s further aspects and creating multivariable models are required for more thorough understanding and optimising of intervention points.]

[Background – Contemporary neuroimaging methods disclosed structural and functional cerebral abnormalities in idiopathic generalized epilepsies (IGEs). However, individual electrical (EEG) abnormalities have not been evaluated yet in IGE patients. IGE patients were investigated in the drug-free condition and after 3-6 month of antiepileptic treatment. To estimate the reproducibility of qEEG variables a retrospective recruited cohort of IGE patients was investigated. 19- channel resting state EEG activity was recorded. For each patient a total of 2 minutes EEG activity was analyzed by LORETA (Low Resolution Electromagnetic Tomography). Raw LORETA values were Z-transformed and projected to a MRI template. Z-values outside within the [+] 1. In drug-free condition, 41-50% of IGE patients showed abnormal LORETA values. 2. Abnormal LORETA findings showed great inter-individual variability. 3. Most abnormal LORETA-findings were symmetrical. 4. Most maximum Z-values were localized to frontal or temporal cortex. 5. Succesfull treatment was mostly coupled with disappearence of LORETA-abnormality, persistent seizures were accompanied by persistent LORETA abnormality. 1. LORETA abnormalities detected in the untreated condition reflect seizure-generating property of the cortex in IGE patients. 2. Maximum LORETA-Z abnormalities were topographically congruent with structural abnormalities reported by other research groups. 3. LORETA might help to investigate drug effects at the whole-brain level.]
