- OBJECTIVE: To evaluate the possible impact of a neutral third party on the patients' responses to health-related quality of life (HRQL) instruments. METHODS: 119 patients operated at the Department of Urology in Lund with radical cystectomy and continent urinary tract reconstruction (continent cutaneous diversion or orthotopic bladder substitution) for locally advanced bladder cancer were included in the study. They were randomly divided in two groups, similar with regard to gender, age, length of follow-up, and type of reconstruction. The EORTC instruments QLQ-C30 and QLQ-BLM30 were sent to the patients. One group; "Lund patients", received the instruments from the Department of Urology in Lund, while the other group; "Stockholm patients", received the instruments from a neutral third party, i.e. "The Project Health and Well-Being" at the Karolinska Institutet in Stockholm. RESULTS: Response rates were high in both groups, 59 out of 60 among Lund patients and 57 out of 59 among Stockholm patients. There were statistically significantly more bowel problems reported in the Stockholm patients than in the Lund patients (p<0.05) in the QLQ-C30 instrument. Regarding type of reconstruction, the Stockholm patients with continent cutaneous diversion scored higher for constipation than the Lund patients (p<0.05), and the Stockholm patients with bladder substitution scored lower for emotional functioning and higher for dyspnoea and economical problems than the Lund patients (p<0.05. There were no statistically significant differences between the Lund patients and the Stockholm patients in the QLQ-BLM30 instrument. CONCLUSION: Though few factors differed between the two groups, the results may indicate that different results are obtained when a study is totally administered and analyzed by a neutral third party as compared with the surgeon or his or her institution. Larger studies are needed to further test this hypothesis.

- Objectives: A large proportion of patients with cutaneous malignant melanoma (CMM) do not experience excess mortality due to their disease. This group of patients is referred to as the cure proportion. Few studies have examined the possibility of cure for CMM. The aim of this study was to estimate the cure proportion of patients with CMM in a Swedish population. Methods: We undertook a population-based study of 5850 CMM patients in two Swedish health care regions during 1996-2005. We used flexible parametric cure models to estimate cure proportions and median survival times (MSTs) of uncured by stage, sex, age and anatomical site. Results: Disease stage at diagnosis was the most important factor for the probability of cure, with a cure proportion of approximately 1.0 for stage IA. While the probability of cure decreased with older age, the influence of age was smaller on the MST of uncured. Differences in prognosis between males and females were mainly attributed to differences in cure as opposed to differences in MST of uncured. Conclusions: This population-based study showed approximately 100% cure among stage IA disease. Almost 50% of patients had stage IA disease and the high cure proportion for this large patient group is reassuring.

- We present experimental measurements and theoretical calculations of single and double ionization time delays in various noble gases using an interferometric method. The measured delays allow us to extract information on the electron correlation.

Assessing BIM performance in building management organisations

Konferensbidrag (refereegranskat)abstract
- This paper presents a literature review into issues related toBuilding Information Modelling(BIM) performance assessment in building management organisations and proposes an agenda for future research addressing how such an approach can be further developed. Performance in use of BIM can be described as a measure or description of how capable and mature a project team or organisation is in terms of developing, using, evaluating or receiving BIM products or services. Although BIM is awell-known and established methodology in building design and construction organisations, when procuring and executing projects, the building management side, encompassingbuilding operations and maintenance, usually lags behind. Adoption of BIM in building management has become a challenge addressed in discussions on what the next step for BIM uptake will be. By adapting and using solutions that, to an extent, have already been developed for other stages in the construction delivery process, BIM can contribute to benefits for the operations/management phase of buildings. In order to prove efficiency and applicability of BIM as a methodology in building management operations, approaches to assess actual performancearenecessary. Thispaper describes development of a possible approach of assessing BIM performance through self-assessment. It is identified that pre-requisites in the form of default performance indicators, referred to as BIM Performance Indicators (BPI) have to be established for such methodology to be possible. In order to distinguish these BPIs, new data through input from practitioners has to be gathered. This paper suggests that a case study aiming to gather data from practitioners for this development is a suitable vehicle for identifying these indicators underpinning assessment of BIM performance specific to organisations within the building management sector. The paper concludes thatappropriate dimensions in which significance for BIM use in building management organisationsshould be sought in a case study are (1) Technology, (2) Knowledge, (3) Communication, (4) Processes and (5) Organisational culture and motivation.
