Experiments were carried out in the genetically hypertensive obese rats of Koletsky type (SHR/N-cp) and in their lean siblings. Regression analysis was performed when plasma triglycerides was used as a dependent variable and plasma insulin, insulin binding to erythrocytes, basal plasma glucose tolerance data were used as independent variables. Coefficient determination (R2) as well as the tests of hypotheses of regression coefficients being zero were used to indicate which independent variables contributed the least in the explanation of dependent variable. This way we reduced the list of variables to give a simpler regression equation. In the control animals insulinemia was found to be dominant independent variable in all groups except SHR/N-cp obese females where the dominant independent variable was represented by the basal plasma glycaemia. Under the terguride treatment only in SHR/N-cp female rats the dominant independent variable remained the same as in controls. In the other groups the dominant independent variable was different in relation to the control animals. Long lasting terguride treatment normalized hypertriglyceridemia only in SHR/N-cp obese females. Thus the data obtained by multiple regression analysis of parameters of lipide and glycide metabolism show the close relationship to alleviating effect of terguride in hypertriglyceridemia.

This research proposes an assessment and decision support model to use when a driver should be examined about their propensity for traffic accidents, based on an estimation of the driver's psychological traits. The proposed model was tested on a sample of 305 drivers. Each participant completed four psychological tests: the Barratt Impulsiveness Scale (BIS-11), the Aggressive Driving Behaviour Questionnaire (ADBQ), the Manchester Driver Attitude Questionnaire (DAQ) and the Questionnaire for Self-assessment of Driving Ability. In addition, participants completed an extensive demographic and driving survey. Various fuzzy inference systems were tested and each was defined using the well-known Wang-Mendel method for rule-base definition based on empirical data. For this purpose, a programming code was designed and utilized. Based on the obtained results, it was determined which combination of the considered psychological tests provides the best prediction of a driver's propensity for traffic accidents. The best of the considered fuzzy inference systems might be used as a decision support tool in various situations, such as in recruitment procedures for professional drivers. The validity of the proposed fuzzy approach was confirmed as its implementation provided better results than from statistics, in this case multiple regression analysis.

The increasing prevalence of autism spectrum disorders (ASD) has led to worldwide interest in factors influencing the age of ASD diagnosis. Parents or caregivers of 237 ASD children (193 boys, 44 girls) diagnosed using the Autism Diagnostic Observation Schedule (ADOS) completed a simple descriptive questionnaire. The data were analyzed using the variable-centered multiple regression analysis and the person-centered classification tree method. We believed that the concurrent use of these two methods could produce robust results. The mean age at diagnosis was 5.8 ± 2.2 years (median 5.3 years). Younger ages for ASD diagnosis were predicted (using multiple regression analysis) by higher scores in the ADOS social domain, higher scores in ADOS restrictive and repetitive behaviors and interest domain, higher maternal education, and the shared household of parents. Using the classification tree method, the subgroup with the lowest mean age at diagnosis were children, in whom the summation of ADOS communication and social domain scores was ≥ 17, and paternal age at the delivery was ≥ 29 years. In contrast, the subgroup with the oldest mean age at diagnosis included children with summed ADOS communication and social domain scores < 17 and maternal education at the elementary school level. The severity of autism and maternal education played a significant role in both types of data analysis focused on age at diagnosis.

Úvod: Hemangiom močového měchýře je vzácný benigní cévní nádor vyskytující se ve všech věkových skupinách. Může se vyskytnout osamoceně nebo v souvislosti se systémovými arterio-venózními malformacemi. Metody: Popisujeme případ hemangiomu močového měchýře u 35letého muže, který byl přijat do naší nemocnice k vyšetření nebolestivé hematurie. Počítačová tomografie a MRI prokázaly zesílení stěny močového měchýře s mnohočetnými kalcifikacemi ve vaskulárním nádoru. Výsledky: Ihned po biopsii a fulguraci léze hematurie vymizela. Vzorek byl patologicky diagnostikován jako kavernózní hemangiom močového měchýře. Aby se zjistil rozsah nádoru, byla provedena angiografie pánve, která neprokázala žádnou vaskulární aktivitu v nádoru. Závěr: Nepřítomnost vaskulární aktivity při angiografii a kalcifikace v mase nádoru pozorované při intravenózní pyelografii, počítačové tomografii a magnetické rezonanci předpokládají, že byl částečně nebo kompletně trombózován a regredoval, což předpokládá konzervativní postup, pokud je možný. Spontánní regrese takového nádoru dosud nebyla v literatuře popsána.
Background: Bladder hemangioma is a rare benign vascular tumor occurring in any age group. It may occur singly or in association with systemic arteriovenous malformations. Methods: We report a case of bladder hemangioma in a 35-year-old man who was admitted to our hospital for the evaluation of painless hematuria. Computerized tomography and MRI demonstrated bladder wall thickening with multiple foci of calcification in the vascular tumor. Results: Immediately after biopsy and lesion fulguration, the hematuria disappeared. The specimen was pathologically diagnosed as cavernous hemangioma of the urinary bladder. To establish the extent of tumor pelvic angiography was performed and showed no vascular activity in tumor. Conclusion: Lack of vascular activity on angiography and the calcifications of the tumor mass as seen on intravenous pyelography, computerised tomography and magnetic resonance suggested that it was partially or completely thrombosed and regressing, suggesting a conservative approach wherever possible. Spontaneous regression of such lesions has not been documented in the literature so far.
