[Melatonin, sleep and the circadian rhythm: theoretical considerations and their chronopharmacological applications ]

BÓDIZS Róbert

[The predictive homeostasis of living organisms is an anticipatory adaptation to rhythmical environmental changes. A good example for this is the circadian rhythm preparing the organism for the alternation of day and night. The circadian rhythm of melatonin production anticipates the timing and duration of nocturnal sleep of human subjects. It also induces a sleep-like stimulusprocessing mode of the brain and - in case of adequate environmental circumstances - a soporific and in part, a sleep-inducing effect. Specificities of melatonin effects on sleep are the reduction of slow-wave EEG activity, as well as the increase in seep EEG spindling and REM sleep time. Like other substances with hypnotic properties, melatonin decreases core body temperature, but has also a strong chronobiotic effect that is expressed as rapid and strong phase shifts of the circadian rhythm, depending on the time of day of melatonin administration. Because light acutely suppresses melatonin production, adequately timed light exposition, containing also low wavelength components, together with exogenous melatonin, could be useful in treating jet-lag syndrome and other circadian rhythm disorders.]

[What worries Hungarian men? - Characteristics of masculine gender role stress]

SUSÁNSZKY Anna, SUSÁNSZKY Éva, KOPP Mária

[INTRODUCTION - The aim of this study was to establish the characteristics of stress associated with male gender role and its relationship to health and to risk behaviours among Hungarian men. SUBJECTS AND METHODS - The present analysis is based on data of the Hungarostudy 2006 survey. Forty-one percent of the participants were men. Eighty nine percent of the male respondents completed the Eisler-Skidmore Masculine Gender Role Stress Scale; data of 1764 persons were analyzed. RESULTS - Anxiety about sexual performance, breadwinner role, and appearance (i.e. tradition factor) causes a much greater burden of stress than anxiety about changing gender relationships (i.e. modernization factor). With the increase of age, stress caused by traditional role expectations significantly decreases; tensions caused by women’s dominance and by situations which demand emotional response and empathy are the highest among middle aged men. Traditional gender role stress is more prevalent among pensioners than among economically active men; stress caused by the modernization of masculine gender role particularly afflicts unemployed men. Married men are to the least extent troubled by female dominance and difficulties in expressing emotions. Of the two dimensions analyzed here (tradition and modernization) only the values on the tradition factor were related to health status, psychological well-being, and frequency of smoking. CONCLUSIONS - Modernization of gender roles represents only a small - if any - stressor in the life of Hungarian men; on the other hand, unsuccessful adaptation to traditional role expectations highly increases the burden of stress and is closely related to smoking.]

Investigation of risk factors, topographic location and stroke mechanisms of unilateral isolated and posterior cerebral ARTERY thalamic infarcts

GÖKCAL Elif, SENGUL Yildizhan, USLU Ilgen Ferda

Aim - In this study, we aimed to examine the risk factors, topographic features and stroke mechanisms of acute ischemic unilateral infarcts of thalamus. Methods - Patient with isolated thalamic infarct and those with posterior cerebral artery (PCA) infarction who were admitted to our hospital between January 2014 and January 2017 with acute unilateral thalamic infarction (TI) were included in this study (isolated thalamic infarction/ isolated TI; thalamic and posterior cerebral artery infarction/PCA+TI). Demographic characteristics and vascular risk factors of the patients were determined. Thalamic infarct areas were recorded topographically as anterior, posteromedial, ventrolateral, posterolateral, more than one area, and variant areas. Stroke mechanism was determined according to the criteria of „Trial of Org 10172 in Acute Stroke Treatment” (TOAST). Patients with isolated TI and PCA TI were compared according to risk factors, stroke mechanism and infarct topography. Results - Forty-three patients with a mean age of 63.3 ± 14.5 years were included in the study. Twenty-eight patients (60.1%) were found to have isolated TI and the remaining 15 patients (34.9%) had PCA+TI. 32.1% of patients with isolated TI had sensory symptoms on presentation, and 60% of patients with PCA-TI had sensorimotor symptoms. The mean age, the mean score on National Institutes of Health Stroke Scale (NIHSS) and the mean frequency of atrial fibrillation were higher in PCA+TI patients than in isolated-TI patients (p: 0.04, p: 0.004, p: 0.02 respectively). 32.6% of the patients had ventrolateral, 30.2% had posteromedial involvement. Ventrolateral topography was seen in 46.7% of the PCA+TI patients, while posteromedial topography was seen in 39.3% of the isolated-TI patients. 53.6% of the isolated-TI had small vessel disease etiology, while 40% of the PCA+TI had cardioembolic etiology, and the other 40% had large artery atherosclerosis. Conclusion - Our study showed that the most ommon stroke mechanism in patients with thalamic infarction is the small vessel disease. Isolated TI and PCA+TI patients differ in terms of etiologic mechanism and infarct topography. Variant territorial involvement and multiple area involvements can be quite common in thalamic infarcts.

[The influence of changes in lifestyle on treatment and prevention of cardiovascular diseases are the objects of surveys in many places of the world. On the basis of clinical trials one can underline that the Mediterranean diet, with enhanced physical activity, changing lifestyle, cessation of smoking, reducing alcohol intake, maintaining normal weight can decrease dyslipidaemia, atherosclerosis and prevent cardiovascular diseases.]

[NON-HDL-CHOLESTEROL AND ITS SIGNIFICANCE]

SIMONYI Gábor

[The role of LDL-cholesterol in cardiovascular risk has been established in a number of studies. According to current recommendations, therefore, the primary goal of lipidlowering therapy is reducing the level of LDL-cholesterol. Of lipid-lowering drugs, statins are the most efficient in reducing cardiovascular risk. According to large studies on statins, however, there is a significant residual risk even in patients receiving aggressive treatment. It is well known that many patients continue to have dyslipidaemia despite statin therapy, and not all patients with cardiovascular disease have elevated LDL-cholesterol levels. These observations indicate that lipids other than LDL-cholesterol also have a role in the development of atherosclerosis. A growing attention is paid to non-HDL-cholesterol as a cardiovascular risk factor. Calculating non-HDL-cholesterol target is easy: LDL-cholesterol measurement plus 0,8. Non-HDL-cholesterol incorporates a number of atherogenic lipoprotein particles [VLDL-cholesterol, IDL-cholesterol, LDL-cholesterol, and lipoprotein(a)]. As the atherogenic effect of apoB-containing lipoproteins (LDL, IDL-C és VLDL) is significant, they may be stronger predictors of coronary heart disease (CHD) risk than LDL-cholesterol is. Considering the strong correlation between apoB and non-HDLcholesterol and the limitations of apoB measurement (standardisation, cost), non- HDL-cholesterol is a more useful parameter and therapeutic target, especially if triglyceride levels are greater than 2.26 mmol/l.]

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

BERECZKI Dániel, VASTAGH Ildikó

[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.]
