- Objective Fast-track concepts have been implemented in hepatopancreatobiliary surgery cancer care to improve postoperative recovery. For optimal postoperative care, patient participation is also required. The aim was to investigate and analyse whether an intervention with patient-owned fast-track protocols (PFTPs) may lead to increased patient participation and improve information for patients who underwent surgery for hepatopancreatobiliary cancer. Methods A quantitative comparative design with a control and intervention group was used. The participants in the intervention group followed a PFTP during their admission. After discharge, the patients answered a questionnaire regarding patient participation. Data analyses were performed with descriptive statistics and ANCOVA. Results The results are based on a total of 222 completed questionnaires: 116 in the control group and 106 in the intervention group. It is uncertain whether the PFTP increased patient participation and information, but its use may indicate an improvement for the patient group. Conclusion A successful implementation strategy for the use of PFTP, with daily reconciliations, could be part of the work required to improve overall satisfaction with patient participation.

- Background Quality cancer care necessitates opportunities for patient participation, supposedly recognizing the individual's preferences and experiences for being involved in their health and healthcare issues. Previous research shows that surgical cancer patients wish to be more involved, requiring professionals to be sensitive of patients' needs. Aims To explore preference-based patient participation in surgical cancer care. Methods A cross-sectional study was conducted. The Patient Preferences for Patient Participation tool (4Ps) was used, which includes 12 attributes of preferences for and experiences of patient participation. Data were analyzed with descriptive and comparative statistical methods. Results The results are based on a total of 101 questionnaires. Having reciprocal communication and being listened to by healthcare staff were commonly deemed crucial for patient participation. While 60% of the patients suggested that taking part in planning was crucial for their participation, they had experienced this only to some extent. Learning to manage symptoms and phrasing personal goals were items most often representing insufficient conditions for preference-based patient participation. Linking Evidence to Action To support person-centered surgical care, further efforts to suffice preference-based participation are needed, including opportunities for patients to share their experiences and engage in the planning of healthcare activities.

- Planning for the disposal of spent nuclear fuel is at an advanced stage in several nations around the world. Licensing of the disposal facility requires correspondingly detailed assessment of the future performance of the facility. With increased site-specific detail available to the assessment, local characteristics play an increasingly important role in determining the potential radiological risk posed by releases to the biosphere. In this paper we go beyond existing reference biosphere models and investigate the potential for specific accumulation mechanisms. The implications for the modelling carried out in long timescale performance assessment are discussed.

The complexation of some radionuclides with natural organics : Implications for radioactive waste disposal
- 1994

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Natural organics like humic substances are important for the speciation, mobility and bioavailability of metals in the environment. This ability necessitates the investigation of what impact humic substances may have on radionuclides that accidentally can escape from radioactive waste repositories. The objective of the present thesis is to contribute to the understanding of how radionuclides are complexed by humic substances as well as cellulose degradation products and how this may influence their adsorption to particularly geological materials.A comparison of characteristics of humic substances from different origins has been carried out in an attempt to give a general picture of the properties of these compounds. Evidence was found that supports the statement that the conformation and the molecular weight of the humic substance molecule are important factors in detennining ionic strength effects. A large fraction of the investigated fulvic acids (FA) had pK,'PP-values around 4.0 which suggestes -COOH functionality.A well-characterized aquatic FA, and its complexation with four different radionuclides (Sr, Eu, Th, U) ha;e been studied. The effect of pH, ionic strength, competing metal ions and different methods of investigation (IEDS and UF) on the complexation was examined. It was found that the influence of pH and ionic strength varied with the method of investigation, but that the ionic strength effect was greatest when applying JEDS. Both methods showed that Eu formed stronger complexes than Sr. Thorium formed the strongest complexes. The hexavalent U seemed to form weaker complexes than Eu, especially at pH values below 4. No effect of competing ions (AI, Fe, Sr) on the Eu-FA complex was noticed and it was suggested that this was due to different binding sites for Eu and the competing ions.The investigation of how FA influences the adsorption of Sr and Eu onto alumina and quartz showed that FA has the ability to both increase and decrease the adsorption of Sr and Eu depending on pH and ionic strength.Cellulose degradation products as well as some organic hexose derivatives were found to decrease the adsorption of Eu onto cement at high pH (> 12). However, this decrease disappeared with time probably due to continued degradation.A general conclusion is that aquatic humic substances maY have a significant impact on speciation and transport properties of tri- and tetravalent elements like Eu and Th as well as hexavalent U, in the presence of high concentrations, of humics (surface waters), butinsignificant effect under most groundwater conditions.

Bokkapitel (refereegranskat)abstract
- The complexation of an aquatic fulvic acid, FA, with Sr2+ and Eu3+ was studied using an ultrafiltration technique and an ion exchange distribution method. The total amount of bound metal (Sr2+ and Eu3+) was measured as a function of pH at low meta! concentrations (trace levels) and constant FA concentration. In the Sr-FA system the bound meta! fraction increased slightly with pH, and the values obtained from the two experimental techniques were comparable. For Eu-FA, according to the ultrafiltration data, the fraction of bound meta! ion was relatively insensitive to pH changes, whereas values from the ion exchange measurements showed a strong and positive dependence on pH. The results are discussed in the light of possible intrinsic problems of the two methods.
