This study aimed to investigate alterations in hemorheology induced by L-carnosine, an anti- oxidant dipeptide, and to determine their relationship to oxidative stress in density-separated erythrocytes of aged and young rats. 28 male Sprague Dawley rats were divided into 4 groups as aged (Aca), young (Yca) L-carnosine groups (250 mg/kg L-carnosine, i.p.) and aged (As), young (Ys) control groups (saline, i.p.). Density separation was further performed to these groups in order to separate erythrocytes according to their age. Blood samples were used for the determination of erythrocyte deformability, aggregation; and oxidative stress parameters. Erythrocyte deformability of Yca group measured at 0.53 Pa was lower than Aca group. Similarly, deformability of least-dense (young) erythrocytes of Yca group was decreased compared to least-dense erythrocytes of Aca groups. Total antioxidant capacity (TAC) of Aca group was higher and oxidative stress index (OSI) lower than As group. Although L-carnosine resulted in an enhancement in TAC of aged rats, this favorable effect was not observed in erythrocyte deformability and aggregation in the dose applied in this study. and G.

Competencies develop and changes throughout a persons life, they can gain or lose, going through various age stages. Their development does not end in youth, but continue on through the adult life. The ability to thing and reflect those thoughts specifically come forward in the center of structure of competency, which grows at the same time as the individual matures. One of the competency types is health competency. Health competency is a relatively new concept; it is not sufficiently researched. Aim of the study was to determine the factors of an adult individual health competency. 827 respondents participated in the study, in the processing of data was used SPSS. Was used factor analysis, analysis of variance with ANOVA and KruskalWallis test and Pearsons correlation. It was found that health competency is affected by several factors. These are: health education, health behavior, and the value of the environment. Each of the sets was distributed to key factors. It is the main factors affecting the health competence, but additional factors are: gender, education and income., Inara Upmale, Andrejs Geske, and Literatura
Cíl: Cílem studie je stanovit prevalenci chronického selhání ledvin u 101 pacientů s monoklonální gamapatií neurčeného významu (MGUS). Typ studie: retrospektivní studie. Materiál a metody: Porovnali jsme glomerulární filtraci odhadovanou ze sérového kreatininu a cystatinu C a hodnotili jsme korelaci mezi koncentrací volných lehkých řetězců v séru a funkcí ledvin. U všech pacientů jsme provedli elektroforézu pro - teinů séra s denzitometrickou kvantifikací monoklonálního imunoglobulinu a změřili jsme koncentraci kreatininu, cystatinu C, volných lehkých řetězců kappa a lambda, β 2 mikroglobulinu. Výsledky: Chronické selhání ledvin jsme nalezli u 38,6 % pacientů na základě odhadu ze sérového cystatinu C a u 34,6 % pacientů na základě odhadu ze sérového kreatininu. B2mikroglobulin má největší počet významných korelací; cystatin C (0,90), CysC GFR (-0,69), Kreatinin (0,70), MDRD GFR (-0,60), MIg koncentrace (0,24), κ FLC (0,22) λ FLC (0,34) a věk (0,40). Tento velký počet korelací lze vysvětlit tím, že β 2mikroglobulin odráží jak zátěž organismu maligními buňkami, tak pokles glomerulární filtrace. Závěr: Chronické selhání ledvin jsme nalezli u 38,6 % pacientů při odhadu glomerulární filtrace z cystatinu C a u 34,6 % při odhadu ze sérového kreatininu. Třída monoklonálního imunoglobulinu může mít vliv na výsledky odhadu glomerulární filtrace ze sérového cystatinu C, odhad glomerulární filtrace ze sérového kreatininu není ovlivněn třídou imunoglobulinu. Diabetici neměli statisticky signifikantně nižší glomerulární filtraci než pacienti bez diabetu mellitu., Background: Renal function is more frequently decreased in patients with monoclonal gammopathy. 10 % of patients with multiple myeloma present with acute renal failure and renal function is included in CRAB criteria for the diagnosis of multiple myeloma. Aim: The aim of this study is to determine the prevalence of chronic renal failure (CRF), defined as a glomerular filtration rate (GFR) below 1.0 ml/s/1.73m 2 , in 101 patients with monoclonal gammopathy of undetermined significance (MGUS). Design: retrospective study Material and methods: We compared GFR estimates from serum creatinine (MDRD GFR) and serum cystatin C (CysC GFR) and looked at the correlation between free light chains (FLC) concentration and renal markers. We performed serum protein electrophoresis (SPE) with quantification of monoclonal intact immunoglobulin (MIg) and measured serum creatinine, cysta - tin C, κ and λ FLC and β 2microglobulin in all patients. Results: We found CRF in 38.6% patients using estimation from serum cystatin C and 34.6 % using estimation from serum creatinine. B2microglobulin has the highest number of significant correlations; cystatin C (0.90), CysC GFR (-0.69), crea - tinine (0.70), MDRD GFR (-0.60), MIg concentration (0.24), κ FLC (0.22) λ FLC (0.34) and age (0.40). The best correlation results may be explained by the fact that β 2microglobulin reflects both malignant cells burden and renal function. Conclusions: We found CRF in 38.6 % MGUS patients using estimation from serum cystatin C and in 34.6 % using estima - tion from serum creatinine. The class of monoclonal immunoglobulin may influence results of glomerular filtration estimated from cystatin C but it does not influence GFR estimated from creatinine. Diabetic patients had not significantly lower GFR than patients without diabetes mellitus., Šálek T., Moravčíková D., Humpolíček P., Tichý M., Palička V., and Literatura
The aim of this study was to determine the prevalence of musculoskeletal problems among Czech dentists and to analyze the factors that affect these disorders. Information was gathered through questionnaire completed by 581 physicians. The questionnaire ascertained general information about physicians including their work habits and the characteristics of their work environment along with the occurrence of musculoskeletal problems as well as their intensity. In the past year the occurrence of at least mild difficulties associated with the locomotive system was reported by 96.9% of dentists surveyed (n = 557), with 66.3% of respondents (n = 381) reporting difficulties ofa moderate or major nature. Most respondents of both sexes indicated neck pain. A statistically significant correlation with the occurrence of musculoskeletal complaints of medium and major intensity was demonstrated for the following factors: sex, age, running a private practice, past injury or musculoskeletal diseases, and the perception of work as psychologically demanding. Musculoskeletal disorders in dentists in Czech Republic are relatively frequent and serious health problem. The causes of these diseases must be identified and appropriate preventive interventions undertaken that will contribute to a reduction in the incidence of these problems. and Z. Sustová, L. Hodacová, M. Kapitán
Cardiac surgery is inseparably linked to the activation of innate immunity cells recognizing danger signals of both endogenous and exogenous origin via pattern recognition receptors such as TLR receptors. Therefore, we followed by flow cytometry TLR2 and TLR4 expression on blood monocytes and granulocytes of patients who underwent coronary artery bypass grafting using beating heart surgery (off-pump, n = 34), with use of standard cardiopulmonary bypass (CPB), (on-pump, n = 30), and miniinvasive CPB (mini on-pump, n = 25), respectively, before, during surgery, and up to 7th postoperative day. TLR2 and TLR4 expression both on monocytes and granulocytes was significantly diminished already at the end of CPB being highly significantly decreased at the end of surgery in all patients' groups. TLR2 and TLR4 expression reached preoperative value at the 1st postoperative day being significantly higher at the 3rd postoperative day. Using intracellular staining we found the peak of TLR2 and TLR4 expression inside of monocytes and granulocytes at the first postoperative day in a subgroup of on-pump patients. In conclusion, TLR2 and TLR4 expression is significantly modulated in patients undergoing coronary artery bypass grafting as a part of adaptive homeostatic mechanisms induced by major surgery. The very surgical trauma is responsible for TLR2 and TLR4 modulation. Surprisingly, cardiopulmonary bypass itself was little contributing to the modulation of TLR2 and TLR4 expression. and J.

The aim of this study is to evaluate the results of total hip arthroplasty in patients with Parkinson's disease during a period of five years, focusing on the assessment of the risks and benefits of surgery. During this period we performed total hip arthroplasty in 14 patients (15 hips) with Parkinson's disease. Patients were evaluated by subjective symptoms and objective findings, with a focus on the use of support while walking and walking distance, severity of Parkinson's disease before surgery and at the time of the last follow-up. During the postoperative period, the following parameters were assessed: length of ICU stay, mobilization, complications, the total duration of hospitalization and follow-up care after discharge. Of the 11 patients (12 hips) followed-up 1-5 years with an average of 3 years after operation 8 cases showed progression of neurological disability. 5 patients (6 hips) showed an increased dependence on the use of support when walking and reduced distance that the patient was able to walk. Subjectively, 10 hip joints were completely painless and 2 patients complained of only occasional mild pain in the operated hip. Complications that were encountered were urinary tract infection (5 patients), cognitive impairment (3 patients) and pressure ulcer (2 patients). We did not observe any infection or dislocation of the prosthesis. Three patients fell and fractured the femur and 3 patients in our cohort died during follow up. Implantation of total replacement is possible with judicious indication after careful evaluation of neurological finding in patients with minimal or mild functional impairment of the locomotor system. Prerequisite for a good result is precise surgical technique and optimal implant position with balanced tension of the muscles and other soft tissues around the hip. and PG. Mathew, P. Sponer, T.

The pilot study deals with the clinical results of the regenerative therapeutical method in intraosseous periodontal defects done by surgical augmentation procedure using a material of a new generation prepared on the basis of a bioactive glass. A group of 10 individuals were treated properly for chronic periodontitis. Some of treated infraalveolar periodontal lesions, both periodontal pockets and interradicular defects, persisted or recurred in posterior teeth. In order to eliminate them they were indicated for advanced periodontal surgery or regenerative surgical therapy stimulating healing processes of supportive tissues, mostly alveolar bone around treated teeth. Relevant clinical parameters, i. e. values of the pocket depth, gingival recession, and loss of attachment were evaluated before and after the periodontal surgery and compared with each other. The therapy led to significant improvement of clinical parameters in terms of the reduction of pocket depth and loss of attachment values. and R. Slezák, V. Paulusová
Pozadie: Článok sa zaoberá vybranými aspektmi ústretovosti českého zdravotníckeho systému z pohľadu slovenských imigrantov so zameraním na dostupnosť zdravotnej starostlivosti a komunikáciu medzi pacientom a lekárom. Metódy: Kvalitatívna štúdia bola realizovaná prostredníctvom rozhovorov u 20 Slovákov žijúcich v Českej republike. Výsledky: Najväčšie prekážky pri čerpaní zdravotnej starostlivosti vidia respondenti v nedostatočnom počte registračných miest u lekárov primárnej starostlivosti. Naopak respondenti boli spokojní s prístupom českých lekárov. Závery: Pravdepodobným dôvodom ťažkostí slovenských imigrantov pri registrácii u lekárov primárnej starostlivosti je pracovná preťaženosť lekárov., Background: The article deals with selected aspects of health system responsiveness from the perspective of Slovak immigrants in the Czech Republic. It focuses on access to health care and communication between patient and physician. Methods: A qualitative study was conducted through interviews with 20 Slovaks living in the Czech Republic. Results: The biggest obstacles to health care receiving consist, according to respondents, in inadequate number of registration places at primary care physicians. However, respondents were satisfied with physician`s approach in the Czech Republic. Conclusions: The probable reason for the difficulties of Slovak immigrants during registration at primary care physicians is the work overload of physicians in the Czech Republic., Jana Gabrielová, Iva Brabcová, and Literatura
Cieľ: Cieľom výskumu bolo monitorovať a zhodnotiť rozdiely v hodnotení sledovaných indikátorov kvality ţivota pacientov s proliferatívnou a neproliferatívnou diabetickou retinopatiou. Metodika: Výskumnú vzorku tvorili pacienti s diabetickou retinopatiou (DR) v celkovom počte 80. Prvú skupinu tvorilo 27 pacientov s proliferatívnou diabetickou retinopatiou (PDR) a druhú 53 pacientov s neproliferatívnou diabetickou retinopatiou (NPDR). Komparácia prebiehala v závislosti od typu DR. Zber údajov bol realizovaný štandardizovaným dotazníkom NIE VFQ-25 (National Eye Institute – Visual Function Questionnaire) na Očnom oddelení vo Fakultnej nemocnici s poliklinikou (FNsP) J. A. Reimana v Prešove. Výsledky: T-testom boli u oboch komparovaných skupín pacientov zistené významné rozdiely vo všetkých sledovaných ukazovateľoch kvality ţivota: všeobecný zdravotný stav a zrak, problémy s videním do blízka a do diaľky, vplyv ochorenia na dosahovanie ţivotných cieľov, menšia kontrola nad svojím konaním, obmedzenie dĺţky aktivít, obmedzenie zotrvania iba na domáce prostredie, spoliehanie sa na poskytnuté informácie inými ľuďmi, potreba pomoci od iných ľudí. Záver: Čiastočná alebo úplná strata schopnosti vidieť v súvislosti s diabetom má na kvalitu ţivota diabetika s proliferatívnou diabetickou retinopatiou v holistickom poňatí, teda v biologickej, psychickej a sociálnej dimenzii negatívny dopad. Je preto nevyhnutné dostupnými spôsobmi predchádzať tejto chronickej komplikácii., Aim: To monitor and evaluate the differences in the evaluation of monitored indicators of quality of life of patients with proliferative and non-proliferative diabetic retinopathy (DR). Methods: The research sample comprised a total of 80 patients with DR. The first group consisted of 27 patients with proliferative diabetic retinopathy and the second group of 53 patients with non-proliferative diabetic retinopathy. The comparison was carried out according to the degree of DR. The data were collected using the standardized National Eye Institute Visual Function Questionnaire (NEI VFQ-25) at the Ophthalmic Department of J. A. Reiman Hospital in Prešov. Results: In both compared patient groups, T-tests showed significant differences in all studied quality of life parameters: general health and vision, difficulty seeing far away and up close, the impact of the disease on achieving life goals, being limited in control over and in length of their activities, being limited to their homes, relying on the information provided by other people and needing help from others. Conclusion: In a holistic concept, i.e. biological, psychological and social dimensions, partial or complete loss of the ability to see due to diabetes has a negative impact on the quality of life of patients with proliferative DR. Therefore, this chronic complication must be prevented by any available means., Mária Kaščáková, Ľudmila Majerníková, Janka Slaninková, and Literatura
Z 30 166 případů leukemií, evidovaných v českém registru nádorů v letech 1976–2005 bylo 3 937 vícečetných případů spojeno s výskytem jiných novotvarů. Z nich se 2 450 (62,2 %) vyskytlo u mužů a 1 487 (37,8 %) u žen, tj. 14,7% případů u mužů a 11 % u žen ze všech evidovaných leukemií. Po 1 715 primárních leukemiích bylo diagnostikováno 2 064 jiných novotvarů a před 2 222 následnými leukemiemi 2 642 jiných primárních nádorů. Ze 14 krajů se ve třech vyskytlo 35,5 % vícečetných leukemií (Jihomoravský a Severomoravský kraj, Praha). V průměru za 4,9 roku u mužů a 5,5 roku u žen následovalo 35,1 % nádorů kůže a melanom, 16,9 % nádorů trávicích, 13 % dýchacích a 8,4 % močových cest. Očekávaný nízký počet pokročilých klinických stadií u následných nádorů se nepotvrdil: u mužů zahrnoval 43,8 % nádorů dutiny ústní, 41,5 % dýchacích, 34,2% trávicích, 10,6 % močových cest a 15,7 % pohlavních orgánů; u žen 39,4 % dýchacích, 30,6 % močových, 30 % trávicích cest a 28,2 % pohlavních orgánů, 25 % prsů, 25 % dutiny ústní. Bohužel mnoho klinických stadií nebylo v registru nahlášeno. Před následnými leukemiemi bylo nejvíce primárních karcinomů kůže a melanomu u 43,6 % případů jako ukazatel maligního stavu. Do října 2007 přežívalo u mužů jen 12,4 % primárních a 10,3 % následných leukemií, respektive 19,7 % a 14 % u žen. Kolik dalších novotvarů se vyskytne u osmi tisíc přežívajících s leukemií, očekávaných v roce 2015? Rozbory vícečetných novotvarů by mohly osvětlit mechanizmy jejich vzniku a poskytnout náhled na dispenzární péči a preventivní opatření, ze kterých budou mít prospěch rostoucí počty onkologicky nemocných v remisi., A total of 30,166 cases of leukemia, based on the Czech Cancer Registry in 1976–2005, there were notificated 3,937 multiple cases associated with the ocurrence of other neoplasms. Of them there were 2,450 (62.2 %) in males and 1,487 (37.8 %) in females, i.e. 14.7 % cases in males and 11 % in females of total registered leukemia. There were diagnosed 2,064 other neoplasms after 1,715 primary leukemias and 2,642 other primary neoplasms before 2,222 subsequent leukemias. A total of 14 Czech regions were distributed 35.5 % multiple leukemias in the three regions (Southern and Northern Moravia, Prague). In the average interval 4.9 years in males and 5.5 years in females followed 35.1 % cancer of skin and melanoma, 16.9 % digestive, 13 % respiratory and 8.4 % urinary system. The expected low representation of advanced clinical stages in subsequent cancers was not confirmed: in males 43.8 % cancer of oral cavity, 41.5 % respiratory, 34.2 % digestive, 10.6 % urinary and 15.7 % genital organs; in females 39.4 % respiratory, 30.6 % urinary, 30 % digestive and 28.2 % genital organs, 25 % breast, 25 % oral cavity. Unfortunatelly a lot of clinical stages were not registered. Before the subsequent leukemias the most frequent were 43.6 % primary cancers of skin and melanoma as a sign of malignant status. Up to October 2007 in males survived only 12.4 % of primary and 10.3 % subsequent leukemias, respective 19.7 % and 14 % in females. How many other neoplasms will be diagnosed among 8,000 surviving with leukemia, estimated in the Czech Republic in 2015? The analyses of multiple neoplasms should be possible to illuminate the mechanisms of susceptibility to multiple cancers and provide insights into the long-term medical care and preventive interventions that will benefit the growing population of cancer survivors. of subsequent cancers., Edvard Geryk, Radim Štampach, Jiří Kozel, Petr Dítě, Milan Konečný, and Literatura
