[In accordance with the Hungarian health strategy, the authors introduce the results of the „Comprehensive Health Screening of Hungary” (MÁESZ) as of 2016 and the comparative results of 2010-2016. It has been again found that the Hungarian population is at high medical risk from multiple perspectives. The program is supported by 68 professional-scientific societies as well as by various secretary of states and the ministry. So far it has accomplished the complex screening of 159 576 residents and informed 375 879 residents about the right lifestyle, the protection of health and prevention of diseases on the ground. ]

[Bayesian and frequentist T-test and ANOVA]

MOLNÁR D. László

[T-test and ANOVA are just special cases of linear models. With these models measured values of a continuous variable (e.g. blood pressure) can be compared in two or more groups (e.g. treatment groups). In real life medical application of the frequentist linear models the data often fail the assumptions (e.g. normality and equal variances) originally needed to derive the mathematical equations and distributions for these models. Bayesian linear models are robust, flexible and transparent analogues and alternatives of the frequentist models. Bayesian statistical models can also be useful, when the data do comply with the prescribed conditions for the t-test or ANOVA. An advantage of the bayesian method is the possible incorporation of any prior knowledge into the models. It must be borne in mind, however, that there are many frequentist methods that can be used even if the distributions are not normal, or in the case of heteroscedasciticy or other model inadequacy as well. It is worth mentioning that even the frequentist Lasso (least absolute shrinkage and selection operator) is in near relationship with the Bayesian method, since it is a linear regression method, where the traditional fitting algorithm is modified with a constraint, and some information will be discarded in order to focus on the most relevant coefficients and make the model interpretation easy. Cal­culations were performed in R, primarily with the BayesFactor package developed by Morey and Rouder in 2015. ]

[Behavioral therapy of diabetes mellitus]

SAL István, KOHLNÉ Papp Ildikó

[Diabetes is a model disease of behavior therapy. Its treatment is in the hands of patients for the most part, who must make decisions about their treatment every day, which affect their health status, prognosis and risk of developing complications of the disease. This common and complex treatment represents a significant burden for the majority of patients. In practice, a significant number of patients do not follow one or more cornerstones of self-management: physical activity, healthy diet, and use of medication. Based on research results diabetic patients' quality of life and psychological state is significantly worse than those of non-diabetics, which tend to deteriorate the medical collaboration and health status. In addition, certain psychiatric disorders (depression, anxiety, eating disorders), are also more common, which impair the quality of self-treatment as well. Early detection and treatment is of great importance, but in practice, only 10% of patients get psychological treatment, despite the fact that nearly 40% of them experience psychological symptoms. Based on the above, behavior remedial methods are highly recommended to be applied in the field of diabetes care in order upgrade quality of life, although they are not yet considered as commonly accepted in psychoeducation. Our aim is to summarise the practical and proven methods of behavioral remedies in addition to the literature review. In the case study demonstrate the authors the addition of transtheoretical model. The first order condition of self-management is the adoption of the disease and motivation, afterwards comes the teaching of theoretical and practical knowledge, and the ongoing diabetes education. ]

[Diseases of the kidneys due to non-cancer mortality characteristics of Hungary between 2005-2014]

PAKSY András, KISS István

[The authors review the time of 10 years between 2005-2014 concerning the development of the mortality rate of kidney diseases in Hungary. They’ve compared the Hungarian mortality data with the ones from three other countries, namely Austria, the Czech Republic and Germany. The analyses included kidney diseases originated from hypertension, glomerulonephritis and tubulointerstitial kidney diseases, kidney failure and polycystic kidney diseases. They weren’t concerned about kidney tumors or diabetes originated kidney diseases because of the lack of data concerning the latter. The mortality data were retrieved from the KSH Demography Yearbook and the European Detailed Mortality Data-base (DMDB). The statistically examined causes of death only add up to 1.2% of the total causes of death, but with the aging of the population this proportion will surely grow. During the last 10 years, the mortality of cardiovascular diseases decreased significantly, namely the mortality of ischaemic heart disease and stroke, but the mortality of hypertension increased. These processes can also be seen in Austria, the Czech Republic and Germany. The mortality connected to primal kidney diseases decisively concerns people aged over 70. The glomerular diseases’ standardized rate is significantly higher in Hungary than in the compared countries. The tubulointerstitial kidney diseases’ mortality rate decreased over the last 10 years and we are in the middle of the international field in this regard. During the evaluation of the mortality of kidney diseases it is important to consider that in the statistics every death can only have one cause nominated, which can be (correctly) the basic disease causing the kidney disease or in other cases the kidney disease itself. This problem makes it more difficult to compare data internationally. Only 20-30 patients die of acute kidney disease on a yearly basis which is a low mortality rate even by international standards but the above-mentioned problem still exists. Of all of them the chronic kidney disease is the most significant one and between 2005-2014 the number of deaths and their rate connected to it decreased, but with the aging of the population the morbidity of kidney diseases will surely increase. Analyzing the data of all the primer kidney diseases it can be determined that between 2005-2014 the mortality rate showed a decreasing tendency, so our international situation can be viewed positively. It is important to note though that the mortality of this disease type includes patients of lower average age in Hungary than in the more developed countries. The mortality rate of polycystic kidney disease hasn’t changed significantly during the past 10 years. Although some patients live to many years, the average age of the dead is significantly lower compared to the ones of other kidney disease types. The cases below the age of 1 year of the latter add up to 10%. The comparison between the countries concerning the po­lycystic kidney disease shows that the standardized mortality rate is higher in Hun­gary.]

[Current questions on Pneumococcus infections: cardiovascular complications, cardiotoxicity and new opportunities for prevention among elderly people]


[The respiratory tract infections, first of all severe pneumonia are associated with severe cardiovascular adverse events the significance of which that had not been recognised so far. Among the adverse events, the development of acute coronaria syndromes, heart failure, arrhythimias are the most important ones leading to significatly higher mortality even after several years. In the development of acute coronaria syndrome , the proinflammatory activites play the cenral role leading to the instability of coronaria plaques and plaque rupture associated with formation of platelet thrombi. The constriction of coronariae, peripherial vasodilatation and hypoxia also contribute to the deleterius complications. The role of pneumococci in this process seems to be especially significant since this pathogen exhibit a unique direct cardiotoxic effect, namely directly invades the myocardium and produce cardiotoxic substances. As a consequence, impairement of cardiomyocite function and contractility and formation of microscopic lesions in which later collagen deposition and long-term cardiac scarring can be detected. These pathological processes are developed despite of antibiotic treatment, consequently, vaccination against pneumococcal infection seems to be the only method for efficacious prevention of the myocardium damage and cardiovascular adverse events. According to the results of the CAPITA study, the conjugate polisaccharide vaccine decrease the number of pneumococcal pneumonia and invasive pneumococcal infections by 45 and 75% resp. in the elderly population. The recognition of the direct and indirect role of pneumococci in the development of early and late cardiovascluar adverse events gives a new aspect of the beneficial effect of efficacious vaccination.]

[The future of chest X-ray screening in Hungary]

AJKAY Zoltán

[In 2001 4.095.134 chest screening examinations were carried out at 154 fixed and 50 mobile Xray screening stations in Hungary. Currently, screening for tuberculosis is mandatory by law, but a recently issued decree by the Health Minister states that the method is suitable for the screening of lung cancer as well. Unfortunately, the majority of the machines are old and since replacements are long overdue, the assessment with a high technical standard and quality is not always possible. These are the reasons why a plan must be outlined for the necessary improvement and for the renewal of the equipment pool, based on expert opinion. In the literature, there are ongoing spirited discussions on the efficacy of X-ray screening as well as on the possibilities of CT-scans for the identification of lung cancer. The size of the investment needed makes it necessary that costbenefit factors and the possibility of joining the National Health Prevention program should be considered.]

[Results of the comprehensive health screening of Hungary (MÁESZ) in 2017 and comparative results of 2010-2017 specially to hypertension]

BARNA István, KÉKES Ede, DAIKI Tenno, DANKOVICS Gergely, KISS István, A MÁESZ Programbizottsága nevében

[The year 2017 saw the continuation of Hungary’s greatest and to date most comprehensive health screening program started in 2010. The examinations - among them coronary examinations - covered the fields of cardiology and hypertension, they took place in a specially furnished lorry. In the program we measured blood pressure, pulse rate, calculated cardiovascular risk, plasma cholesterol, glucose and uric acid levels. Whole body analysis started with measuring height, weight, abdominal circumference and waist/hip ratio defining target body weight. Following the measurement of body fat and muscle content we decided the surface volume of the abdominal fat and calculated body mass index. Participants and results of the examinations of the people who have presented themselves for the test since 2017 have been evaluated. In the Program a total (52.2%) women and (47.8%) men were tested at 204 locations. Upon data processing with the help of a query 21.9% of the participants reported suffering from hypertension. The screening truck has been to 1505 places is Hungary, and travelled 183,335 km, 135,879 people have participated in comprehensive screening. The average systolic blood pressure among women was in the normal range up to the age of 55 years. The diastolic blood pressure levels were in the normal range for both sexes (with the exception of the age group 46-55 of men where it exceeded the upper limit of the normal range by a minimal extent). Among men stage 1 hypertension was the most frequent status for all age groups; blood pressures above 140/90 were measured for 39% of subjects from age 18 onwards. Conclusions: Thanks to the vast information obtained through the program a comprehensive picture has been drawn about Hungary’s present health status not only on a regional or cross sectional level but as it was described in the program, too.]

[The clinical significance of peripheral and central blood pressure form the neurologist’s point of view]


[Hypertension - affecting both the large and the small cerebral vessels - is the most frequent risk factor for cerebrovascular disorders manifesting in stroke, hypertensive encephalopathy or vascular dementia. The central pressure measured at the proximal part of the aorta has more important role in the development of vascular hypertrophy and carotid atherosclerosis than the pressure measured in the brachial artery. Central aortic pressure more accurately reflects the filling conditions of the left ventricle and thus the pressure conditions affecting the cerebral vascular system, than brachial pressure values, therefore possibly predicts more reliably the risk of cardiovascular events than brachial pressure values. Features of the stiffness of large arteries (like pulse wave velocity) more directly reflect the chronic effect of ageing, hypertension and diabetes than brachial or even central aortic pressure. Therefore in upcoming clinical trials arterial stiffness and central aortic pressure should be considered as possible surrogate endpoints. Antihypertensive treatment is an important part of primary and secondary stroke prevention. Decreasing blood pressure in hypertensive subjects significantly decreases the risk of stroke and other vascular events, and the extent of risk reduction primarily depends on the extent of the decrease in blood pressure. Several factors should be considered when choosing from treatment options. The use of traditional β blockers - partly due to their smaller effects on central blood pressure - decreased recently. Further observations will decide on the role of third generation β blockers in the prevention of cardiovascular mortality and morbidity.]

[Dizziness - vertigo Warning symptoms in vertebrobasilar ischemia - Part I. ]


[Dizziness and vertigo - like headache - are the most common complaints which leads patients to visit the doctor. In spite of the headache - which may be primary (e.g. migraine) or symptomatic - dizziness and vertigo do not appear to be a separate nosologic entity but rather the symptoms of several neurological disorders. For differential diagnosis, interdisciplinary thinking and activity is needed because the vestibular, neurological and psychiatric disorders might have a common role in the development of symptoms and further overlapping can also occur. The vascular disorders of the vertebrobasilar system are discussed in detail in this review. The importance, occurrence and causes of vertigo as a warning symptom is in the focus. The author draws attention to life-threatening conditions with acute onset in cases of the posterior scale ischemia and emphasizes the importance of the correct and early diagnosis. The author tries to clear up the nihilistic aspect in treating of stroke and stresses the necessity of thrombolysis and interventional radiological procedures which may be the only chance for the recovery of the patients. The pharmacological prevention of recurrent vascular events is also important and obligatory for the clinicians.]
