[Neuroendocrine background of atherosclerosis and cardiovascular damages in durable stress]

[Chronic stress is associated with increased levels of cortisol and catecholamines as well as with an enhanced activity of the sympathico-sensory nervous system. These neuroendocrine events influence both directly and indirectly the lipid and glucose metabolism as well as inflammatory immune reactions. Stress effects directly cause vascular damage and atherosclerosis via the renin-angiotensin system (RAS). Besides RAS, activities of monocytes/macrophages and the sympathico-sensory nervous system lead to local cardiovascular inflammation and cell hypertrophy. Transactivation between G-protein coupled adrenoceptors and tyrosine kinase receptors as well as the switching between β1- and β2- adrenergic receptors play an important role in the development of cardiac hypertrophy and heart failure. In all chronic neuroendocrine diseases that are associated with increased activity of the sympathetic nervous system, the development of cardiovascular damages needs to be considered.]

[Bradykinin-cytokin-storm and its pathomechanism in very severe Covid-19]

SZÉKÁCS Béla, VÁRBÍRÓ Szabolcs, KÉKES Ede, DEBRECZENI Lóránd

[The authors review the pathomechanism of severe COVID-19 leading to systemic uncontrollable inflammation, thrombotic events and other complications. The review includes the extremely complex interactions between the infecting coronavirus and the in loco cellular-tissue contact system, the kinin-kallikrein and the renin-angiotensin systems. Authors critically evaluate some potential therapeutic interventions aiming at the mitigation of the dominant bradykinin-cytokine storm in the background of severe COVID-19 by inhibiting bradykinin formation, facilitating its degradation, or blocking either the B2 receptor or the bradykinin induced cytokine response.]

[Chronic stress in the development of essential hypertension. Role of rilmenidine in the treatment of stress induced hypertension]

SIMONYI Gábor

[Hypertension is an independent risk factor of cardiovascular diseases. Several factors contribute to its development, including chronic stress, which may induce hypertension by increasing sympathetic activity. The signs of increasing sympathetic activity can be primarily detected in the initial phase of hypertension, which is characterized by the increase in cardiac output. In addition to the hemodynamic consequences (increase in cardiac output, tachycardia, coronary vasoconstriction, proarrhythmia), the increase in sympathetic activity has many harmful effects. Numerous metabolic (insulin resistance, dyslipidemia), structural and trophic effects (endothelial dysfunction, vascular hypertrophy, myocardial hypertrophy), as well as thrombotic and humoral processes (procoagulation, enhancement of thrombocyte aggregation, sodium retention, activation of the renin-angiotensin-aldosterone axis) may develop and consequently damage body functions at many targets. Several different antihypertensive drug classes are available for reducing increased sympathetic activity, including peripheral alpha and beta blockers and centrally acting drugs. First generation antihypertensive drugs with central mechanisms of action (e.g. clonidine, guanfacine, alpha-methyldopa) is currently rarely administered and only for a few indications as they have a significant adverse events profile. Among centrally acting, second generation drugs, rilmenidine stimulates imidazoline-I1 receptors and thus beneficially influences mild or moderate hypertension that involves enhanced sympathetic nervous system activity.]

[Comparative analysis of job and life satisfaction among theatre nurses in Hungary and Germany]

MÁTÉ Szilvia, PHIL. TIGGES-LIMMER Katharina, PUSZTAFALVI Henriette

[The aim of the study: The objective of the study was to assess and compare job and life satisfaction affected by workplace problems, stress, rewards, success and social support. We analyzed the coping strategies applied by the employees to solves the above problems. Material and method: The anonymous data collection was carried out in October, 2015 by applying AVEM and an own-edited socio-demographic questionnaire among theatre nurses from Hungarian and German clinics. Results: The employees evaluated stressful situations and problems differently in the two groups examined. Job satisfaction was equally important for both groups, but it affected life satisfaction of the Hungarian employees to greater extent. The stress management of the Hungarian employees was more effective in spite of the fact that German nurses used more coping strategies. Social support had a positive effect on overcoming the workplace problems in both groups. Conclusions: Job satisfaction of the nurses has a beneficial effect on their life satisfaction. The ability to divide work and private life and stress management are different among the nurses. Job satisfaction can be improved by workplace health promotion programs.]

[HANS SELYE 70 YEARS LATER: STEROIDS, STRESS ULCERS & H. PYLORI]

SZABÓ Sándor

[Although Hans Selye is mostly known for his discovery & development of the stress concept, he also introduced the first physiologically sound, structure-activity classification of steroids that was also based on the chemical structure of steroids in 1943. He not only introduced the names of glucocorticoids & mineralocorticoids but discovered the anti- & pro-inflammatory properties, respectively, of these steroids in animal models. Furthermore, he not only described the first stress-induced gastric ulcers in rats (1936) & characterized the first human ‘stress ulcers’ during the air-raids in London during World War II (1943). Thus, Selye was a much more productive & creative scientist than it is generally considered.]

[A brief survey is offering of debates on two long-standing questions in stress studies and theories: 1) question of stress nonspecificity (i.e. homo- or heterogeneity in stress responses), and 2) what is the functional role of central catecholamines in stress mechanisms, especially in stress signaltransduction and in the realization of stress responses.]
