[Cardiovascular prevention - Opportunities of risk reduction, 2010]

NAGY András Csaba

[10 years of experience following the millennium has confirmed again that data on long term cardiovascular morbidity and mortality can be influenced by effective prevention most substantially. Growing body of knowledge and experience in the field of modern cardiovascular prevention is available, but novel and novel milestone studies have been published leading to updating of guidelines, however, we cannot be satisfied with the results. Evidence suggest that despite recent efforts, Hungarian cardiovascular morbidity and mortality has not been reduced significantly and except for some success - acute ST elevation myocardial infarction care in accordance with the European standard - we are behind the other EU countries in cardiovascular mortality of the active (age 30-65 years) age group. Recently several interesting contradiction has been published in the field of prevention, like the effectiveness of aspirin as primer prevention, which changes our common prevention conception. Data have to be also addressed, which can explain the controversial results from a different point of view. Now we are talking about the results of REALITY study, which highlight not only the noncompliance of the patient but that of the physician as well.]

[The drug-treatment of atherosclerosis by statins]

KÉKES Ede

[The pathogenesis of atherosclerosis is a complex and complicated process. The rule of some factors (lipoproteindeposition, oxidative stress, lipid peroxidation, endothel dysfunction, etc) is well known, but others are not yet clarified. Conventional, metabolic and some special residual factors have also influenced for the starting process. One of them, the lipid profile is the most important. Statins are able to decrease the lipid levels - LDL cholesterol - significantly to the physiological level. These drugs are essential for the primer and secunder cardiovascular prevention moreover it is advisable to give in acute coronary syndrome as well. The most excellent statin is rosuvastatin, because of beneficial effect to decreasing LDL cholesterol level and cardiovascular events. Rosuvastatin is able to produce a regression of atherosclerotic process int he vessel walls. Presumably this effect can be explained by their pleiotrop property.]

[The series gives a brief overview on the discovery of the juxtaglomerular apparatus (JGA), an interesting story, as well as on details of its structure and function down to the molecular level. The discovery of JGA, i.e., a phylogenetically ancient organ, is a fine example of the close morphological and functional correlations characteristic of living organisms. Presented are the JGA related misconcepts and the underlying theoretical and practical difficulties. Utilization of the most modern methods, such as atomic force microscopy, as well as the in vivo multiphoton laser microscopy revealed previously unrecognized phenomen highlighting the ambiguities of textbook information, accepted paradigms. The author is looking for relationship between the new and provocative theoretical research and clinical consequences of pharmacological interventions. He shows that JGA is not only a participant of the salt-water balance and blood pressure regulation, but it can also play a significant role in the pathogenesis of the major public diseases. Finally, he makes an attempt to analyze the current research directions that predict some potential scientific discoveries and describe some general lessons from his own research career.]

[Effects of nasal provocation with a single-dose allergen on the explicit and implicit memory of physically active and inactive patients with ragweed allergy]

TOKODI Margaréta, CSÁBI Eszter, KIRICSI Ágnes, SCHULTZ Rebeka, MOLNÁR H Andor, ROVÓ László, BELLA Zsolt

[Background and purpose - Allergy is an endemic disease and has a considerable impact on the quality of life. This study aimed to measure the effect of active allergic rhinitis on memory functions of physically active and inactive patients with ragweed allergy. Methods - Memory functions were assessed before and after allergen exposure. Participants in both groups were provoked nasally with 30 IR/mL ragweed allergen in each nostril. Explicit memory was measured with story-recalling and implicit memory was investigated with reaction time task. Results - In neuropsychological assessments athletes performed significantly better, compared with the control group after allergen provocation in short-term and long-term memory functions. There was no difference between the groups in the implicit tasks. Athletes have achieved better results after provocation, comparing to the baseline test and the tests that measured short-term and long-term memory functions. Conclusion - Short-term disturbing factors, e.g. swollen nasal mucosa, sneezing, and watery eyes after provocation did have not caused deterioration in cognitive functions. A single-shot allergen in high doses have caused an increase of mental concentration, which was more pronounced in athletes.]
