[The importance of anticoagulant therapy in patients with artial fibrillation in stroke prevention – summary of international data and novel therapeutic modalities]


[The most common cardiogenic cause of ischaemic stroke is atrial fibrillation which increases the probability of stroke five-fold and doubles case fatality. Based on international data the incidence of atrial fibrillation is approx. 2% however this rapidly increases with age. The necessity of using oral anticoagulants in the prevention of non-valvular atrial fibrillation related stroke is decided based on estimated stroke risk. The CHADS2 and the more predictive CHA2DS2-VASc scales are used for this purpose while the bleeding risk of patients treated with anticoagulant may be estimated by the HAS-BLED scoring scale. For decades oral anticoagulation meant using vitamin-K antagonists. Based on international data we can see that rate of anticoagulation is unacceptably low, furthermore most of the anticoagulated patients aren’t within the therapeutic range of INR (INR: 2-3). A lot of disadvantages of vitamin-K antagonists are known (e.g. food-drug interaction, need for regular coagulation monitoring, increased risk of bleeding), therefore compounds with new therapeutic target have been developed. The novel oral anticoagulants (NOAC) can be divided in two major subgroups: direct thrombin inhibitors (dabigatran etexilate) and Xa-factor inhibitors (rivaroxaban, apixaban, edoxaban). These products are administered in fix doses, they less frequently interact with other medications or food, and regular coagulation monitoring is not needed when using these drugs. Moreover several studies have shown that they are at least as effective in the prevention of ischaemic stroke than the vitamin-K antagonists, with no more haemorrhagic complications.]

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


[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. ]

[Practical use of meta-analyses in predicting disease risk, outcome, and therapy response in breast cancer]


[Breast cancer is globally the most frequent malignant disease in women with increasing incidence. Meta-analyses using data from a large set of patients combining genetic and standard clinicopathological features provide valuable models in predicting disease risk, outcome and therapy response. With the advent of molecular technologies, the amount of available data generated for each tumor and each patient is growing exponentially. The increased data availability allows the development of new innovative systems enabling to discover more effective prognostic and predictive biomarkers. The goal of this review is to summarize meta-analyses that utilize data from countless patients to provide breast cancer risk prediction (Gail-model, Claus-model, BRCApro, IBIS, BOADICEA), and prediction of prognosis and expected therapy response (PREDICT, Magee). In the last part of the review we introduce online analytical tools (KMplot, ROCplot) developed to examine, rank and validate new prognostic and predictive biomarker candidates.]

[White-coat and masked hypertension]


[White-coat hypertension is a heterogenous clinical entity, that includes patients with lower and higher cardivascular risk. Its prognosis is relatively benign, when it is not associated with other cardiovascular risk factors. Therefore, cardiovascular risk evaluation has utmost importance in patients with white-coat hypertension for the determina­tion of appropriate treatment. Masked hy­per­tension, however, is not a benign pheno­type, as it has been proven. Its early recognition, regular follow-up and effective anti­hypertensive drug treatment are mandatory. ]

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


[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. ]

[Non-invasive evaluation of cardiovascular risk in pediatric chronic kidney disease patients]

BÁRCZI Adrienn, DÉGI Arianna Amália, KIS Éva, REUSZ György

[Cardiovascular diseases are the leading cause of mortality and morbidity in children with chronic kidney disease (CKD). Similar to adults, children with CKD experience a high burden of traditional and uremia-associated risk factors. Recent years, several studies were published in connection with cardiovascular risk factors, patomechanism, and early markers of cardiovascular diseases. Early signs of cardiomyopathy, such as left ventricular hypertrophy or dysfunction, and markers of atherosclerosis, such as increased intima-media thickness of the carotid artery or increased wall stiffness of the aorta are frequently present in early stages of CKD in children. As prevention is important in pediatrics, the evaluation of subtle changes of the cardiovascular system provide opportunity for early treatment and that enables children to develop normally and have a better long-term quality of life. Recently, newer non-invasive cardiovascular imaging modalities have been emerged to diagnose subclinical alterations of the heart and vessels in this specific population with kidney disease. In this review, we provide an overwiev of the emerging imaging techniques used to detect early subclinical organ damage in pediatric chronic kidney disease patients.]

Hyperhomocysteinemia in female migraineurs of childbearing ages


Background and purpose - Migraine is a risk factor for ischemic stroke in women of childbearing ages. Previous researches revealed a higher prevalence of hyperhomocysteinemia in migraineurs. Possible differences on the frequencies of hyperhomocysteinemia between migraine with aura and migraine without aura could contribute the established variances in stroke risk between these migraine types. Therefore, we aimed to search if the frequency of hyperhomocysteinemia was different between these subtypes of migraine or not. Methods - We analyzed the findings of serum homocysteine levels in female migraineurs of 16-49 years old who admitted to our outpatient clinic. Results - Homocysteine level was elevated in 13.3% of study population. There were not any significant differences on median serum homocysteine levels between migraine with aura (8.0 mikromol/L) and without aura (8.5 mikromol/L). (p=0.426) The frequencies of hyperhomocysteinemia were also similar (9.1% versus 16.7%, respectively; p=0.373). Correlation analyses did not reveal any linear correlation between ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura (p=0.417 and p=0.647, respectively). Similarly, any linear correlation between disease ages and homocysteine levels either in group of migraine with aura or in group of migraine without aura was not detected (p=0.359 and p=0.849, respectively). Conclusion - The median serum homocysteine levels and the frequencies of hyperhomocysteinemia are similar between migraine with aura and without aura in women of childbearing ages. Therefore, the variances on stroke risk ratios between these types of migraine are probably not originated from the differences of serum homocysteine status.

[Carvedilol in chronic kidney disease]

CSIKY Botond

[Chronic kidney disease (CKD) is endemic affecting 850 million people worldwide. Adequate antihypertensive treatment slows the progression of the kidney disease and also decreases the mortality of this population. Because of the comorbidities and the high cardiovascular risk beta-blockers have to be administered frequently in these patients. Carvedilol is a 3rd generation non-selective beta-blocker with alpha- 1 receptor blocking and antioxidant properties. It is metabolically neutral, it does not increase the risk of new onset diabetes and it does not increase the patients’ body weight. In some animal models of CKD and in several human CKD studies carvedilol has shown to have nephroprotective properties and it also decreased the cardiovascular risk in combination therapies.]

[Statins for elderly people, in primary prevention?]


[In a recent, retrospective cohort study, statin usage in primary prevention was found being not beneficial for patients (i) without diabetes over 75 years of age, and (ii) with diabetes over 85 years of age (75-84 years total mortality of diabetics was also lower). These findings are in sharp contrast to the two outstanding, double-blind, placebo controlled, randomized, a primary prevention studies done with rosuvastatin. Of these, 50% reduction in LDL-C in JUPITER was associated with a 50% reduction in risk and 25% reduction in LDL-C in HOPE-3 with 25% reduction in risk. Furthermore, subgroup analyzes did not indicate lower efficacy for the elderly. The recommendation of the European Atherosclerosis Society for primary preventions of the elderlies recommending consideration of statin use in these cases (Class IIa) is particularly relevant, especially in the presence of other risk factors such as hypertension. In the primary prevention lipid treatment, we can see quite clearly till 75 years of age and hopefully, we will even further after learning about the results of STAREE, a study that is designed to elderly and in which 40 mg atorvastatin is applied.]

[Modalities of the therapy of patients with high cardiovascular risk]


[International and Hungarian guidelines emphasize the need of the combinations in the therapy of hypertension. Single pill combinations (SPC) are preferred. The importance of the treatment reducing cardiovascular risk is underlined by the fact that in most hypertensive patients other cardiovascular risk factors, among them most frequently dyslipidemia is present. In addition to antihypertensive drugs these patients should be treated also with those decreasing plasma lipids. Adherence / persistence to therapy of patients is greatly improved by the use of single pill combinations. Today we also have SPCs decreasing both, blood pressure and plasma lipids. Among them there is the combination containing amlodipine and atorvastatin. Several international and Hungarian clinical studies have been conducted. Results of these investigations have been described in several publications. In this paper I summarise the most important results of some of these studies. ]
