Kvalitet i praksisstudier i sykepleier- og vernepleierutdanning

Background: Clinical training in health and social care educations are important in the development of professional competence. Evidence indicates that there are major quality differences in clinical practice in health- and social studies. Purpose: To examine what key players related to clinical practice in nursing and social education believes provides quality. Method: Focus Group Interview where students, supervisor and teachers participated in all groups. Results: Students learning in practice presupposes a knowledge base of the student, a learning environment with adapted responsibilities and coping capabilities, and a relationship with the supervisor who promotes both recognition and needed correction. The supervisor's role can be strengthened through individual competence, clearer support from boss and co-workers, and more emphasis on triangular cooperation with the college. Conclusion: There is a large overlap in the understanding of what in practice is all about quality. The perspectives of the three actors appear primarily as mutually complementary.publishedVersio

Expression of the progenitor marker NG2/CSPG4 predicts poor survival and resistance to ionising radiation in glioblastoma

Glioblastoma (GBM) is a highly aggressive brain tumour, where patients respond poorly to radiotherapy and exhibit dismal survival outcomes. The mechanisms of radioresistance are not completely understood. However, cancer cells with an immature stem-like phenotype are hypothesised to play a role in radioresistance. Since the progenitor marker neuron-glial-2 (NG2) has been shown to regulate several aspects of GBM progression in experimental systems, we hypothesised that its expression would influence the survival of GBM patients. Quantification of NG2 expression in 74 GBM biopsies from newly diagnosed and untreated patients revealed that 50% express high NG2 levels on tumour cells and associated vessels, being associated with significantly shorter survival. This effect was independent of age at diagnosis, treatment received and hypermethylation of the O6-methylguanine methyltransferase (MGMT) DNA repair gene promoter. NG2 was frequently co-expressed with nestin and vimentin but rarely with CD133 and the NG2 positive tumour cells harboured genetic aberrations typical for GBM. 2D proteomics of 11 randomly selected biopsies revealed upregulation of an antioxidant, peroxiredoxin-1 (PRDX-1), in the shortest surviving patients. Expression of PRDX-1 was associated with significantly reduced products of oxidative stress. Furthermore, NG2 expressing GBM cells showed resistance to ionising radiation (IR), rapidly recognised DNA damage and effectuated cell cycle checkpoint signalling. PRDX-1 knockdown transiently slowed tumour growth rates and sensitised them to IR in vivo. Our data establish NG2 as an important prognostic factor for GBM patient survival, by mediating resistance to radiotherapy through induction of ROS scavenging enzymes and preferential DNA damage signalling

Psychometric properties of the Norwegian translation of the Tinnitus Handicap Inventory (THI-NOR)

Objective: To assess the psychometric properties of a Norwegian translation of the Tinnitus Handicap Inventory (THI-NOR). Design: A survey was sent by post to patients referred with tinnitus as their main complaint to an audiology department. Patients completed a Norwegian version of the Tinnitus Handicap Inventory (THI-NOR), a Norwegian translation of two revised subscales of the Abbreviated profile of hearing aid benefit (APHAB), the General Health Questionnaire (GHQ-12) as well as questionnaires measuring coping expectancies (TOMCATS) and neuroticism (EPI). Study sample: Ninety-nine persons with tinnitus. Results: No associations were found between THI-scores or pure-tone audiometry, gender or age. The proposed subscales of the original THI were not formed by responses from responders. The total scale shows good psychometric properties. Significant correlations were found between distress as measured by the GHQ-12, coping expectancies as measured by TOMCATS and neuroticism as measured by EPI and THI scores. Conclusions: THI-NOR has psychometric properties similar to those of the Danish translation (THI-DK), from which it was adapted, and to the original THI. THI-NOR seems to be a valid measure of the impact of tinnitus on a person’s everyday life. Findings show that the suggested subscales of the questionnaire should be interpreted with caution

Importance of personality and coping expectancy on patient-reported hearing disability, quality of life and distress level: a study of patients referred to an audiology service

Purpose: According to the World Health Organization (WHO), hearing loss (HL) affects up to 15% of the world’s adult population. Coping and personality are hypothesized to underlie quality of life (QoL) and distress scores. We aimed to study the importance of personality and coping in persons with HL for self-reported hearing disability, QoL, and distress. Methods: A cross-sectional survey was carried out, including one hundred and fifty-eight adults seeking hearing aids. Pure-tone average hearing thresholds (PTA) were determined for each ear. A revised version of the Abbreviated Profile of Hearing Aid Benefit (APHAB) served as a measure of self-reported hearing disability. Further, the generic part of the European Organization for Research and Treatment (EORTC) QoL questionnaire and the General Health Questionnaire (GHQ) (distress measure) were answered. Levels of neuroticism and the Theoretically Originated Measure of the Cognitive Activation Theory of Stress (TOMCATS) coping expectancy were determined. Results: Hearing disability was determined by PTA (better ear) and level of neuroticism. Distress and QoL were determined by neuroticism and coping. Conclusion: More neuroticism was associated with worse outcome for the variables hearing disability, distress, and QoL. Helplessness and hopelessness were associated with worse hearing disability, increased distress, and lowered QoL. Patient reported hearing disability was also associated with PTA (better ear). There is a need to investigate further the associations between hearing disability and QoL to psychosocial parameters

Multimodal approach to assess tumour vasculature and potential treatment effect with DCE-US and DCE-MRI quantification in CWR22 prostate tumour xenografts.

The aim of this study was to compare intratumoural heterogeneity and longitudinal changes assessed by dynamic contrast-enhanced ultrasound (DCE-US) and dynamic contrast-enhanced magnetic resonance imaging (DCE-MRI) in prostate tumour xenografts. In vivo DCE-US and DCE-MRI were obtained 24 h pre- (day 0) and post- (day 2) radiation treatment with a single dose of 7.5 Gy. Characterization of the tumour vasculature was determined by Brix pharmacokinetic analysis of the time-intensity curves. Histogram analysis of voxels showed significant changes (p < 0.001) from day 0 to day 2 in both modalities for kep , the exchange rate constant from the extracellular extravascular space to the plasma, and kel , the elimination rate constant of the contrast. In addition, kep and kel values from DCE-US were significantly higher than those derived from DCE-MRI at day 0 (p < 0.0001) for both groups. At day 2, kel followed the same tendency for both groups, whereas kep showed this tendency only for the treated group in intermediate-enhancement regions. Regarding kep median values, longitudinal changes were not found for any modality. However, at day 2, kep linked to DCE-US was correlated to MVD in high-enhancement areas for the treated group (p = 0.05). In contrast, correlation to necrosis was detected for the control group in intermediate-enhancement areas (p < 0.1). Intratumoural heterogeneity and longitudinal changes in tumour vasculature were assessed for both modalities. Microvascular parameters derived from DCE-US seem to provide reliable biomarkers during radiotherapy as validated by histology. Furthermore, DCE-US could be a stand-alone or a complementary technique. Copyright © 2015 John Wiley & Sons, Ltd
