- The erythro form of the lignin model compound 1-(3,4-dimethoxyphenyl)-2-(2-methoxyphenoxy)-1,3-propanediol (1) was oxidized with laccase/ABTS, lead(IV) tetraacetate (LTA), lignin peroxidase/H2O2, cerium(IV) ammonium nitrate (CAN) and Fenton's reagent. The product profiles obtained with the different oxidants were compared after separation, identification and quantification of the products using HPLC, UV-diode array detector and electrospray ionization mass spectrometry in positive ionization mode. The oxidants generated different product profiles that reflected their different properties. Oxidation with laccase/ABTS resulted almost exclusively in formation of 1-(3,4-dimethoxyphenyl)-3-hydroxy-2-(2-methoxyphenoxy)-1-propanone (2). Oxidation with LTA resulted in more 3,4-dimethoxybenzaldehyde (3) than ketone 2. Lignin peroxidase and CAN gave similar product profiles and aldehyde 3 was the predominant product (only small amounts of ketone 2 were formed). Oxidation with Fenton's reagent resulted in the formation of more aldehyde 3 than ketone 2 but the yields were very low. CAN served as an excellent model for the lignin peroxidase-catalyzed oxidation, while the laccase-mediator system, LTA and Fenton's reagent provided distinctly different product profiles. Erythro-1-(3,4-dimethoxyphenyl)-1,2,3-propanetriol was present among the products obtained on oxidation with LTA, lignin peroxidase, CAN and Fenton's reagent. The differences in redox potential between the oxidants afford an explanation of the diverse product patterns but other factors may also be of importance. The reactions leading to cleavage of the β-ether bond with formation of 1-(3,4-dimethoxyphenyl)-1,2,3-propanetriol (veratrylglycerol) were found to proceed without affecting the configuration at the β-carbon atom.

- Public health policies in most European countries are concerned with how to keep older people living independently with a qualitatively good life in the community as long as possible. However, knowledge about what may characterise those seemingly 'healthy' older people is sparse. The aim of the study was to investigate the characteristics of a sample of people (75+) reporting various degrees of Quality of Life (QoL) with respect to QoL in different areas, as well as self-rated health, health problems, social support, everyday activities and sense of coherence. A postal questionnaire was sent out in spring 2001 to a randomly selected population-based sample (n= 600) in the southern parts of Sweden. A two-step cluster analysis was performed (n= 385, mean age 84.6, SD = 5.7) with 'present QoL' as clustering attribute. Three groups were disclosed, classified as high, intermediate and low present QoL, of which 33.8% could be regarded being at risk of low QoL. Those with low present QoL (18.4%) were the oldest and most vulnerable, a majority were women with 'poor or bad' self-rated health, high frequencies of health problems, low total QoL, low social support and sense of coherence and less physically active. Those with high present QoL (47.8%) reported more 'excellent or good' self-rated health, physical activity, satisfactory social support and higher sense of coherence and total QoL than the other two groups. Those with intermediate present QoL (33.8%) had more of 'poor or bad' self-rated health, more health problems were less physically active, had lower total QoL and sense of coherence, and less social support than those with high present QoL. The sample seemed to reflect the ageing process in that the respondents were at different stages of ageing. However, the fact that the level of social support, sense of coherence and self-rated health followed the same curve as QoL may indicate that some are more vulnerable to low present QoL given the same health and these should be targeted in preventive programmes since they report low QoL.

- Objective: To describe and compare self-reported health complaints, overall and health-related quality of life and to investigate how health complaints, age, gender, marital status, living and dwelling conditions and socio-economy predicted overall and health-related quality of life. Data and Method: A sample of 469 persons (aged 75-99) responded to a postal questionnaire. Multiple linear regression analysis was used to examine possible predictors. Result: Self-reported health complaints such as pain, fatigue and mobility impairment significantly predicted low overall and health-related quality life. Women had significantly lower overall and health-related quality of life than men, and a significantly higher degree of self-reported health complaints. The regression models had more similarities than differences, implying that the overall quality of life instrument were sensitive to physical influences only supposed to be detected by health-related quality of life instruments. Several of the health complaints predicting low quality of life are amenable for being relieved by nursing care. In the care of older people nurses need to assess for several health complaints simultaneously and be aware of their possible interaction when outlining interventions. Nurses are able to facilitate early detection of health complaints negatively affecting quality of life by implementing more pro-active preventive work as well as a higher degree of thorough and systematic assessments. It also seems important to consider that older woman's and men's needs for high quality of life may differ.

The experience of quality of life among older people
- 2005

- Although quality of life has been in the focus of attention for over a decade there are few studies available investigating, how the old and the oldest old experience their quality of life or what quality of life actually means for them? To illuminate this, eleven in-depth interviews were conducted with six women and five men (80+) living in their home. An interpretative hermeneutic phenomenological analysis revealed that quality of life in old age meant a preserved self and meaning in existence. Maintained self-image meant that the older people experienced a coherent life with an intact meaning. How quality of life was valued depended on the meaning the old people attached to the areas of importance as well as how they were evaluated. Additionally, areas not generally included when measuring quality of life became discernible. The meaning of home, how life was viewed, thoughts about death and dying, and telling ones story proved to be areas of importance for their perception of quality of life. Thus, indicating that older people's view of quality of life is more complex than some of today's most commonly used quality of life instruments capture and that quality of life assessment tools needs to measure beyond pure health indices. For nursing care the use of life review in everyday care, and an open way towards existential topics as well as a family oriented care along with preventive work helping people to remain in their own homes may enhance their experience of quality of life.

Condition-dependent individual decision-making determines cyprinid partial migration

- Partial migration is a common phenomenon among many animals and occurs in many types of ecosystems. Understanding the mechanisms behind partial migration is of major importance for the understanding of population dynamics and, eventually, ecosystem processes. We studied the effects of food availability on the seasonal partial migration of cyprinid fish from a lake to connected streams during winter by the use of passive telemetry. Fish with increased access to food were found to migrate in higher proportion, earlier in the season, and to reside in the streams for a longer period compared to fish with decreased access to food. Furthermore, fewer unfed migrants returned to the lake, indicating higher overwinter mortality. Our results suggest that individual fish trade off safety from predation and access to food differently depending on their body condition, which results in a condition-dependent partial migration. Hence, our main conclusion is that individual decision-making is based on assessment of own condition which offers a mechanistic explanation to partial migration. Moreover, this may be of high importance for understanding population responses to environmental variation as well as ecosystem dynamics and stability.

Tidskriftsartikel (refereegranskat)abstract
- In this exploratory research, multiple case studies of various types of festivals in two countries reveal how festival managers work with stakeholders and who they are. Stakeholders' roles are categorized as regulator, facilitator, coproducer, supplier, collaborator, audience, and the impacted, and the results show clearly that key stakeholders take multiple roles affecting the organization. Practical implications are drawn for event managers regarding the identification, evaluation, and management of stakeholder relationships. Drawing on resource dependency and stakeholder theories, a conceptual model is presented that illustrates the conclusion that festivals and events are produced within and by a set of managed stakeholder relationships. Recommendations are made for development of this line of research and theory building.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundWomen's perceptions of quality of care during episodes of breast inflammation have been scantily explored. It was the objective of the present study to describe a cohort of breastfeeding women with inflammatory symptoms of the breast during lactation regarding demographical variables, illness history and symptoms at first contact with a breastfeeding clinic and to explore their physical health status, psychological well-being and perceptions of quality of care received, at a six-week postal follow-up.MethodsThis is a descriptive study set at a midwife-led breastfeeding clinic in Sweden, which included a cohort of women with 210 episodes of breast inflammation. The women had taken part in a RCT of acupuncture and care interventions and were recruited between 2002 and 2004. Of the total cohort, 176 (84 %) responded to a postal questionnaire, six weeks after recovery.ResultsOf the 154 women for whom body temperature was recorded at the first visit, 80 (52%) had fever ranging from 38.1°C to 40.7°C. There was no significant difference between those with favourable outcomes (5 or less contact days) and those with less favourable outcomes (6 or more contact days) for having fever or no fever at first contact. Thirty-six percent of women had damaged nipples. Significantly more women with a less favourable outcome (6 or more contact days) had damaged nipples. Most women recovered well from the episode of breast inflammation and 96% considered their physical health and 97% their psychological well-being, to be good, six weeks after the episode. Those whose illness lasted 6 days or more showed less confidence in the midwives and in the care given to them. Twenty-one (12%) women contacted health care services because of recurring symptoms and eight of the 176 responders (4.5%) were prescribed antibiotics for these recurring symptoms. A further 46 women (26% of the responders) reported recurring symptoms that they managed without recourse to health care services.ConclusionInitial fever may not be indicative of outcomes for women with inflammatory breast symptoms and treatment by antibiotic therapy may be necessary less often than has been supposed. Women who are also suffering from damaged nipples may need special attention. Those with protracted symptoms were less satisfied with care and showed less confidence in caregivers. International research collaboration might help us find the optimal level of antibiotic therapy for this group of women. This is an important consideration for the global community.

- Objectivesto further compare acupuncture treatment and care interventions for the relief of inflammatory symptoms of the breast during lactation and to investigate the relationship between bacteria in the breast milk and clinical signs and symptoms.Designrandomised, non-blinded, controlled trial of acupuncture and care interventions.Settinga midwife-led breast feeding clinic in Sweden.Participants205 mothers with 210 cases of inflammatory symptoms of the breast during lactation agreed to participate. The mothers were randomly assigned to one of three treatment groups, two of which included acupuncture among the care interventions and one without acupuncture. All groups were given essential care. Protocols, which included scales for erythema, breast tension and pain, were maintained for each day of contact with the breast feeding clinic. A Severity Index (SI) for each mother and each day was created by adding together the scores on the erythema, breast tension and pain scales. The range of the SI was 0 (least severe) to 19 (most severe).Findingsno significant difference was found in numbers of mothers in the treatment groups, with the lowest possible score for severity of symptoms on contact days 3, 4 or 5. No statistically significant differences were found between the treatment groups for number of contact days needed until the mother felt well enough to discontinue contact with the breast feeding clinic or for number of mothers prescribed antibiotics. Significant differences were found in the mean SI scores on contact days 3 and 4 between the non-acupuncture group and the two acupuncture groups. Mothers with less favourable outcomes (⩾6 contact days, n=61) were, at first contact with the midwife, more often given advice on correction of the baby's attachment to the breast. An obstetrician was called to examine 20% of the mothers, and antibiotic treatment was prescribed for 15% of the study population. The presence of Group B streptococci in the breast milk was related to less favourable outcomes.Key conclusions and implications for practiceif acupuncture treatment is acceptable to the mother, this, together with care interventions such as correction of breast feeding position and babies’ attachment to the breast, might be a more expedient and less invasive choice of treatment than the use of oxytocin nasal spray. Midwives, nurses or medical practitioners with specialist competence in breast feeding should be the primary care providers for mothers with inflammatory symptoms of the breast during lactation. The use of antibiotics for inflammatory symptoms of the breast should be closely monitored in order to help the global community reduce resistance development among bacterial pathogens.
