Glioblastoma is the most common and malignant brain malignancy worldwide, with a 10-year survival of only 0.7%. Aggressive multimodal treatment is not enough to increase life expectancy and provide ...good quality of life for glioblastoma patients. In addition, despite decades of research, there are no established biomarkers for early disease diagnosis and monitoring of patient response to treatment. High throughput sequencing technologies allow for the identification of unique molecules from large clinically annotated datasets. Thus, the aim of our study was to identify significant molecular changes between short- and long-term glioblastoma survivors by transcriptome RNA sequencing profiling, followed by differential pathway-activation-level analysis. We used data from the publicly available repositories The Cancer Genome Atlas (TCGA; number of annotated cases = 135) and Chinese Glioma Genome Atlas (CGGA; number of annotated cases = 218), and experimental clinically annotated glioblastoma tissue samples from the Institute of Pathology, Faculty of Medicine in Ljubljana corresponding to 2-58 months overall survival (n = 16). We found one differential gene for long noncoding RNA
whose overexpression showed correlation to poor patient OS. Moreover, we identified overlapping sets of congruently regulated differential genes involved in cell growth, division, and migration, structure and dynamics of extracellular matrix, DNA methylation, and regulation through noncoding RNAs. Gene ontology analysis can provide additional information about the function of protein- and nonprotein-coding genes of interest and the processes in which they are involved. In the future, this can shape the design of more targeted therapeutic approaches.
We examined whether driving-related reaction times differ between 26 healthy adults (university students) and 26 patients after stroke, and how distractors and leg-dominance affect reaction time and ...correctness of reactions of healthy adults. Reaction times were measured with the Fiat Mediatester driving simulator using 18-lamps reaction test (simple reaction time measurement) and choice reaction test (scored as reaction time and number of correct reactions). There was no statistically significant difference between the groups in simple reaction time. As expected, choice reaction times of the healthy adults were shorter on average and their reactions more accurate than those of the patients. Under the influence of distractors, healthy adults had statistically significantly longer choice and simple reaction times and made fewer correct choices compared to normal conditions. Leg dominance statistically significantly affected choice reaction times and correctness of reactions, but not simple reaction times. Our results confirm validity and usefulness of the Fiat Mediatester driving simulator for research purposes.
Sub-solidus phase relations in the ternary CaO–La2O3–TiO2 system at 1400°C in air were determined. The multi-phase samples were prepared by a solid-state reaction method, whereas the single-phase ...samples for the structure analysis of selected solid solutions were prepared by a wet-precipitation method in order to provide good homogeneity of the starting mixtures. The phases in the prepared samples were characterized by X-ray powder diffraction (XRD), scanning electron microscopy (SEM) and energy-dispersive spectroscopy (EDS). The oxides form seven ternary compounds in the equilibrium state, many solid solutions (which extend across a broad concentration region), and a large, single-phase area based on the CaTiO3 solid solution. The structures of several new phases – solid solutions on the tie lines CaTiO3–Ca3La4Ti3O15 and La2TiO5–Ca3La4Ti3O15 – were determined in detail.
The Measure of Processes of Care (MPOC) is a questionnaire for parents used to evaluate the behaviours of healthcare providers. We applied its 20-item version (MPOC-20) to explore the associations ...between parental evaluation of processes of care and child, parent and family characteristics in Slovenia. A novelty of our approach was the emphasis on the role of a key person. Parents of 235 children who were admitted as inpatients or outpatients of six institutions (hospitals and health centres) because of chronic illness or disability participated in the study. Parents were asked to fill in a general questionnaire on several characteristics of the child, child's health problems, the family and the therapy programmes, and MPOC-20. Univariate associations of the five MPOC-20 scale scores with child, parent and family characteristics were tested first. Multiple linear regression was used for modelling scale scores in relation to child, parent and family characteristics. The analyses singled out availability of a key person as the factor most consistently and unequivocally influencing parental satisfaction. We also found a general positive effect of male sex of the child on the MPOC-20 scores. Neither the present age of children nor age at the onset of health problems was found to be associated with MPOC-20 scores. We found no notable association of the number of health problems with the MPOC-20 scores, but observed clear differences when comparing parental satisfaction with processes of care between different participating institutions.
In the process of developmental (re)habilitation, determination of the functional abilities of an individual is an important step. For that we need appropriate measurement instruments. Because we do ...not have such measurement instruments in Slovenia, we chose the Pediatric Evaluation of Disability Inventory (PEDI), translated it, and applied it in daily practice to assess its usefulness and applicability. The purpose of the study was to find out whether the functional abilities of the population of Slovene children evaluated with the Pediatric Evaluation of Disability Inventory is comparable to the American normative data. We also wanted to assess the possible influence of gender, parent education, community size, and the presence of siblings on children's functional abilities. The Pediatric Evaluation of Disability Inventory was administered in the form of a structured interview to the parents of 147 healthy children in three age groups (0.5—1 year, 3—3.5 years, and 5—5.5 years) in different health care centers in Slovenia. Data analysis showed significant differences in functional skills and caregiver assistance scale scores when comparing the Slovene sample with the American normative data, particularly in the youngest age group. Slovene children were found consistently to be different (scoring either higher or lower) from American children at comparable ages in several functional skills and caregiver assistance scales. The analysis also confirmed the importance of gender and the presence of siblings for gaining higher scores on some of the functional skills and caregiver assistance scales. The level of parent education did not prove to have a significant impact on the results. Our results suggest that the American normative data are not completely appropriate for reference purposes in Slovenia. The results are in agreement with the findings of other studies, demonstrating the importance of ascertaining intercultural differences. We believe that adaptation and norming of the Slovene version of the Pediatric Evaluation of Disability Inventory are necessary before using the instrument in clinical practice in our country.
