Health-related quality of life (HRQoL) has become an important outcome in the evaluation of kidney transplantation (KT). Although the medical and sociodemographic predictors of HRQoL in patients after KT are well known, there is still a lack of knowledge about the psychological factors involved. This study focuses on the role of personality and actual psychological distress in predicting HRQoL after KT. Sociodemographic (gender, age, education, average income), medical (glomerular filtration, serum albumin, number of co-morbid diseases) and psychological data (neuroticism, extroversion, psychological distress) were collected from 177 (60.5% male subjects; 48 ± 12.1 years) kidney transplant recipients, and physical and mental HRQoL were measured using the SF-36. A univariate general linear model analysis was performed. Higher physical HRQoL was associated with younger age, higher education and income, a low number of co-morbid diseases, lower neuroticism and distress. Higher mental HRQoL was associated with higher education and income, longer time from KT, higher extroversion, lower neuroticism and distress. In both physical and mental HRQoL, actual distress was the best predictor, even when controlled for neuroticism. These results confirm the importance of psychological distress in patients and its impact on their HRQoL after KT and can be applied in intervention programs focused on increasing HRQoL. © 2009 European Society for Organ Transplantation.

Purpose: To explore how social support is associated with anxiety and depression in Parkinson's disease (PD) patients controlling for gender, disease duration and disease severity.Methods: The sample consisted of 124 patients (52.4% male; mean age 68.1 ± 8.4 years; mean disease duration 6.3 ± 5.5 years). Anxiety and depression were measured with the Hospital Anxiety and Depression Scale, social support with the Multidimensional Scale of Perceived Social Support and disease severity with the Unified Parkinson Disease Rating Scale. Data were analyzed using linear regression.Results: Gender, disease duration, disease severity and social support explained 31% of the total variance in anxiety in younger PD patients but did not significantly contribute to the explanation of depression. In the older group, this model explained 41% of the variance in depression but did not significantly contribute to the explanation of anxiety.Conclusion: PD patients experience the positive influence of social support differently according to age. In the younger group, disease duration plays the primary role regarding anxiety. In the older group, poor social support especially from friends is associated with more depression after controlling for the relevant variables.Implications of RehabilitationPD is a disease of older age with a neurodegenerative character and treatment should focus on increasing quality of life.Anxiety and depression are common co-morbidities in PD patients.The support network should also be screened regularly and involved in enhancing the quality of life. © 2014 Informa UK Ltd.

Effects of the probiotic (PRO) Lactobacillus plantarum and of the combination of PRO and the prebiotic (PRE) inulin enriched with oligofructose (2%), and PRO with Lini oleum virginale (O) on counts of lactobacilli and coliforms and enzymatic activities in faeces of rats were studied. The rats (n = 60) were divided into 5 groups of 12 subjects. The animals were fed on a high fat diet (10%) for 8 weeks of experiment. Colon cancer was induced by the application of 1,2-dimethylhydrazine (DMH) twice a week in a dose of 20 mg/kg s.c. in groups G2-G5. The rats in group 1 (control 1) received a diet without any supplements. The rats in group 2 (control 2) received 1,2 DMH without any supplements. The rats in group 3 received PRO, group 4 PRO and PRE, and group 5 received PRO and O. A significant decrease (P < 0.05) of coliforms was found out after the application of PRO, PRO-O, and PRO-PRE in comparison with control group G2. Significantly higher (P < 0.05) counts of lactobacilli were determined after the application of PRO-O and PRO-PRE. Significantly lower (P < 0.001) activities of β-galactosidase, β-glucuronidase and α-glucosidase were observed in PRO, PRO-PRE and PRO-O, while in the case of the enzyme β-glucosidase the activity was lower only after the addition of PRO-O. The protective effect of lactobacilli was observed in the order PRO-O, PRO-PRE, and PRO. It was shown that combinations of PRO-O and PRO-PRE had a synergistic effect which was higher than the effect of administering only PRO.

Physical and screen-based activity in adolescents plays a crucial role in future health outcomes. Therefore, the aim of the study was to examine the associations of physical activity and screen-based activity with behavioural and psychosocial characteristics of school-aged children.Data on 11, 13 and 15 years old elementary school pupils (N=9,014; mean age=13.59) who participated in the cross-sectional Health Behaviour in School-aged Children 2009/2010 study in the Czech Republic and the Slovak Republic were analyzed. The associations of vigorous physical activity and screen-based activity with substance use, violent behaviour, eating habits and school-related outcomes adjusted for age were explored using logistic regression.Vigorous physical activity was positively associated with some of the health-related behaviours (smoking, breakfast consumption, vegetable and fruit consumption) and school related outcomes (perceived school achievement and school pressure), with gender and country based differences. Screen-based activity was significantly associated with all examined health-related behaviours and school related outcomes with only some country and gender based differences.Vigorous physical activity is positively associated with healthy development of adolescents. Screen-based behaviour shows an inverse relationship with adolescents healthy development, especially in the group of 11 and 13 years old children. Supporting physical activity conducive environments might lead to a reduction in screen-based behaviour in adolescents and should be highlighted in health-promoting strategies.

Objectives: Prostate cancer (PCa) represents one of the most complicated human tumors and, like many others malignancies, arises from progressive genetic and epigenetic alterations. Among all recognized epigenetic alterations, aberrant DNA methylation (hypo- and hypermethylation) is the most important and the best characterized change in PCa. Background: We analyzed GSTP1, APC and RASSF1 gene promoter hypermethylation in urine DNA of ten previously non-treated prostate-diseased patients. Methods: For the purpose, the quantitative real-time methylation specific PCR (MSP) with primers designed for amplification of methylated bisulfite-converted human DNA, followed by melting procedure, was currently optimized. Results: GSTP1 gene promoter hypermethylation was detected in 2 and 1 out of 5 patients with biopsy-confirmed PCa using the primers covering the 3' and 5' CpG regions of the promoter, respectively. The APC gene promoter hypermethylation was found in neither of PCa or non-PCa patients and the RASSFI gene promoter hypermethylation was found in some non-PCa and not in all PCa patients. Conclusions: Our results suggest that GSTP1 gene promoter hypermethylation can be detected in urine DNA of PCa patients with real-time MSP followed by melting. This enables evaluation of its potential as a useful biomarker in the diagnosis and prognosis of PCa.

Strong state of science supports the health benefits of regular physical activity in young population. Therefore, it is understandable that the factors that influence physical activity in adolescent population can aid the proposal of more effective interventions that will help young people to become more active. Previous studies, investigating correlates of youth physical activity, life style, demographic characteristics and body fat have produced conflicting results. All study participants completed a standard questionnaire on selected correlates of parents’ involvement in physical activity and selected demographic characteristics. Percentage of body fat accumulation in freshman students was investigated by the means of Omron BF 511 device. Results were summarized using a comprehensive analysis for young female adults aged 18 to 20,n=1139, from University ofP.J. Šafárik in Košice 2012. Our cross-sectional study was part of VEGA project No. 1/1343/12 “Selected risk factors of obesity and its prevention by physical activity”. The variables that were consistently associated with higher percentage of body fat in students were lack of parents’ adoption to healthy lifestyle and participation and guidance of their own kids towards physical activity. On the contrary, we did not find statistical significance between selected demographic characteristics and higher percentage of body fat in the adolescent sample. In order to improve the state of health in the young population, we recommend health promotion activity campaign with relevant tailored messages that should target the parent population. These consistently related variables should be confirmed in prospective studies, and intervention to improve the modifiable variables should be developed and evaluated in order to improve overall healthy behavior of young population. © 2016, Univerzitet u Travniku.

Photosensitizers (PSs) in photodynamic therapy (PDT) are, in most cases, administered systemically with preferential accumulation in malignant tissues; however, exposure of non-malignant tissues to PS may also be clinically relevant, when PS molecules affect the pro-apoptotic cascade without illumination. Hypericin (Hyp) as PS and its derivatives have long been studied, regarding their photodynamic and photocytotoxic characteristics. Hyp and its derivatives have displayed light-activated antiproliferative and cytotoxic effects in many tumor cell lines without cytotoxicity in the dark. However, light-independent effects of Hyp have emerged. Contrary to the acclaimed Hyp minimal dark cytotoxicity and preferential accumulation in tumor cells, it was recently been shown that non-malignant and malignant cells uptake Hyp at a similar level. In addition, Hyp has displayed light-independent toxicity and anti-proliferative effects in a wide range of concentrations. There are multiple mechanisms underlying Hyp light-independent effects, and we are still missing many details about them. In this paper, we focus on Hyp light-independent effects at several sub-cellular levels—protein distribution and synthesis, organelle ultrastructure and function, and Hyp light-independent effects regarding reactive oxygen species (ROS). We summarize work from our laboratories and that of others to reveal an intricate network of the Hyp light-independent effects. We propose a schematic model of pro-and anti-apoptotic protein dynamics between cell organelles due to Hyp presence without illumination. Based on our model, Hyp can be explored as an adjuvant therapeutic drug in combination with chemo-or radiation cancer therapy. © 2016 by the authors; licensee MDPI, Basel, Switzerland.

HEART2D was a multinational, randomized, controlled trial designed to compare the effects of prandial insulin versus basal insulin on risk for subsequent cardiovascular (CV) outcomes in patients with type 2 diabetes (T2D) after acute myocardial infarction (MI). Trial design was based on the hypothesis that 2.5 mmol/L postprandial blood glucose (BG) difference between groups would result in risk reduction of 19 to 23% over the planned follow up period (18-36 mo) in the group with lower postprandial BG. One thousand one hundred and fifteen (1115) patients were randomized [prandial strategy (N = 557), basal strategy (N = 558)]. HEART2D was stopped after futility rule implementation at the fourth interim analysis. The risk of a first combined adjudicated CV events in the prandial group (N = 174, 31.2%) and basal (N = 181, 32.4%) groups was similar (HR = 0.98; 95% CI [0.8, 1.21]). The results of HEART2D left the question of the role of postprandial hyperglycemia in diabetic CV disease unanswered. Here, we discuss possible reasons for this outcome, including characteristics of daily BG profiles in the two treatment groups, event rate, risk factors other than standard CV risk factors and glycemic variables. The main reasons for this outcome of HEART2D study could be smaller than expected on-study differences between the study groups in postprandial hyperglycemia, and low event rate. Further trials with larger patient populations and improved designs, focusing also on diabetic patients with lower cardiovascular risk and lower baseline HbA(1c) levels are needed in order to shed more light on this important clinical problem.

The Social Norms Approach, with its focus on positive behaviour and its consensus orientation, is a health promotion intervention of relevance to the context of a Health Promoting University. In particular, the approach could assist with addressing excessive alcohol consumption.This article aims to discuss the link between the Social Norms Approach and the Health Promoting University, and analyse estimations of peer alcohol consumption among European university students.A total of 4392 students from universities in six European countries and Turkey were asked to report their own typical alcohol consumption per day and to estimate the same for their peers of same sex. Students were classified as accurate or inaccurate estimators of peer alcohol consumption. Socio-demographic factors and personal alcohol consumption were examined as predictors for an accurate estimation.72% of male and 51% of female students were identified as having accurate estimations about the amount of alcoholic drinks consumed per day by their peers. Male students, older students, those studying year 3 and above, and Turkish and Danish students were more likely to accurately estimate their peers alcohol consumption. Independent from these factors, students accurate estimation of peers drinking decreased significantly with increasing personal consumption.As accurate estimates of peer alcohol consumption appear to affect personal drinking behaviour positively, social norms interventions targeted at correcting possible misperceptions about peer alcohol use among students may be a useful health promotion tool in the context of a health promoting university.
