- To improve health care for older persons, we need to learn more about ageing, e.g. identify protective factors and early markers for diseases. The Gothenburg H70 Birth Cohort Studies (the H70 studies) are multidisciplinary epidemiological studies examining representative birth cohorts of older populations in Gothenburg, Sweden. So far, six birth cohorts of 70-year-olds have been examined over time, and examinations have been virtually identical between studies. This paper describes the study procedures for the baseline examination of the Birth cohort 1944, conducted in 2014-16. In this study, all men and women born 1944 on specific dates, and registered as residents in Gothenburg, were eligible for participation (n=1839). A total of 1203 (response rate 72.2%; 559 men and 644 women; mean age 70.5years) agreed to participate in the study. The study comprised sampling of blood and cerebrospinal fluid, psychiatric, cognitive, and physical health examinations, examinations of genetics and family history, use of medications, social factors, functional ability and disability, physical fitness and activity, body composition, lung function, audiological and ophthalmological examinations, diet, brain imaging, as well as a close informant interview, and qualitative studies. As in previous examinations, data collection serves as a basis for future longitudinal follow-up examinations. The research gained from the H70 studies has clinical relevance in relation to prevention, early diagnosis, clinical course, experience of illness, understanding pathogenesis and prognosis. Results will increase our understanding of ageing and inform service development, which may lead to enhanced quality of care for older persons.

- ObjectivesThe use of the Injustice Experience Questionnaire (IEQ) in psychological assessment of individuals with chronic pain is supported by research. The psychometric properties of the Swedish version, the IEQ-S, has not yet been evaluated. Hence, the aim was to investigate structural validity, and concurrent criterion validity of the IEQ-S against the Work Ability Index (WAI), the Pain Catastrophizing Scale (PCS-SW), the Patient Health Questionnaire 9-item depression module (PHQ-9), and the Generalized anxiety disorder 7-item scale (GAD-7). Internal consistency and test-retest reliability were also studied.MethodsSixty-five participants, referred to a University hospital, with a pain duration over three months were consecutively sampled. They completed the IEQ-S at admission and again within six weeks. A confirmatory factor analysis was performed for the study of structural validity. Concurrent criterion validity was evaluated using Spearman’s correlation coefficient. Internal consistency reliability for the full IEQ-S was calculated using the Cronbach’s alpha. Test-retest reliability was calculated using an Intraclass Correlation Coefficient (ICC).ResultsThe median total score (0–48, where high scores indicate high levels of injustice) at admission (test 1) was 27.0 (n=64), 25th percentile=15.3, 75th percentile=37.8, range=3–48 points. A one-factor model was supported with item-loadings between 0.67–0.92. Spearman’s correlation coefficient between the IEQ-S and the WAI (n=56) was r S =−0.46; the PCS-SW (n=63) was r S =0.68, the PHQ-9 (n=64) was r S =0.50 and the GAD-7 (n=64) was r S =0.57, p<0.01. Cronbach’s alpha was 0.94 (n=64). The ICC was 0.80 (n=55), with a 95% confidence interval, ranging between 0.69–0.88.ConclusionsOur study supported structural validity and concurrent criterion validity of the IEQ-S against other measures of psychological constructs and work ability. It also supported the internal consistency reliability of the IEQ-S and the test-retest reliability with a retest interval up to six weeks, was good. These findings support the use of the IEQ-S as an adjunct tool to assess appraisals of injustice in patients with chronic pain who are referred to tertiary care in Sweden. The added value might be identification of those who are at risk for slow or no improvement in their pain condition over time, and sick-leave, but this has to be confirmed in future studies.

Experiences of pain and associations between pain, disease severity and individual quality of life in people with motor neuron diseases
- 2019

Licentiatavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Many people with the incurable and often times fatal motor neuron diseases have pain, but there is lack of knowledge about people’s experiences of living with pain. Further, the correlation between pain and their quality of life is not well understood, and previous studies have not used individual quality of life, namely that people with their own words express what quality of life is. The aim of these studies was to explore the experiences of pain and the association between pain and quality of life in people with MND.Methods: Study I was explorative about the individual experience of pain, while study II was correlational between pain, pain severity, disease severity and IQOL. Study I was qualitative, whereas study II used both qualitative and quantitative analysis.Results and conclusions: People with motor neuron diseases experienced pain to have multiple characteristics and impact. However, the results emphasise that the individual experienced some pain characteristics as difficult and that pain could worsen functions that were already affected by the disease. The experience was also that it could be challenging to manage pain. However, the symptom of pain could pass unnoticed in contacts with healthcare professionals (study I). The three most important areas for individual quality of life in both participants with and without pain were: Social relations, followed by Activities for amusement and relaxations, and Being in the outdoor environment. Individual quality of life was noticed to be good regardless of pain. Pain and pain severity were not found to be associated with satisfaction of individual quality of life in patients with motor neuron diseases, neither was disease severity. The results support previous findings, that strong associations between symptoms of MND and IQoL are not obvious. However, this does not infer that pain in people with MNDs should be neglected and undertreated. On the contrary, it seems to be important for healthcare to pay more attention to pain in people with motor neuron diseases and that pain continuously is measured, individually treated and followed. Regardless of whether persons with MND have pain or not, the results point to the importance of healthcare professionals providing support to not only the patient but also the patient’s family and friends, as well as assisting in various forms of relaxing activities and possibility of being in the outdoor environment.

- OBJECTIVE: To study changes in cerebrospinal fluid (CSF) protein markers of blood-CSF barrier integrity and immunological reactions during surgical stress. SUBJECTS AND METHODS: Thirty-five patients without neurological or psychiatric disorders undergoing knee replacements had CSF and serum samples drawn from spinal and arterial catheters before, 3 h after and the morning after surgery. RESULTS: Serum albumin decreased during surgery and CSF albumin decreased during and after surgery, and, as a consequence, the CSF/serum albumin ratio decreased significantly during the study period, especially after the intervention. In contrast, CSF concentrations of beta-2-microglobuline (beta2M) increased significantly during surgery and remained high. The CSF general marker beta-trace protein (betaTP) remained unchanged. CONCLUSIONS: Central nervous system protein reactions to a non-neurological surgical intervention include sharply decreased permeability of albumin into the CSF and signs of intrathecal inflammatory activity.

Physical activity in subjects with multiple sclerosis with focus on gender differences : a survey
- 2014

Tidskriftsartikel (refereegranskat)abstract
- Background: There is increasing research that examines gender-issues in multiple sclerosis (MS), but little focus has been placed on gender-issues regarding physical activity. The aim of the present study was to describe levels of physical activity, self-efficacy for physical activity, fall-related self-efficacy, social support for physical activity, fatigue levels and the impact of MS on daily life, in addition to investigating gender differences. Methods: The sample for this cross-sectional cohort study consisted of 287 (84 men; 29.3%) adults with MS recruited from the Swedish Multiple Sclerosis Registry. A questionnaire was sent to the subjects consisting of the self-administrated measurements: Physical Activity Disability Survey - Revised, Exercise Self-Efficacy Scale, Falls-Efficacy Scale (Swedish version), Social Influences on Physical Activity, Fatigue Severity Scale and Multiple Sclerosis Impact Scale. Response rate was 58.2%. Results: Men were less physically active, had lower self-efficacy for physical activity and lower fall-related self-efficacy than women. This was explained by men being more physically affected by the disease. Men also received less social support for physical activity from family members. The level of fatigue and psychological consequences of the disease were similar between the genders in the total sample, but subgroups of women with moderate MS and relapsing remitting MS experienced more fatigue than men. Conclusions: Men were less physically active, probably a result of being more physically affected by the disease. Men being more physically affected explained most of the gender differences found in this study. However, the number of men in the subgroup analyses was small and more research is needed. A gender perspective should be considered in strategies for promoting physical activity in subjects with MS, e. g. men may need more support to be physically active.

Tidskriftsartikel (refereegranskat)abstract
- Background: The benefits of physical activity in persons with Multiple Sclerosis (MS) are considerable. Knowledge about factors that correlate to physical activity is helpful in order to develop successful strategies to increase physical activity in persons with MS. Previous studies have focused on correlates to physical activity in MS, however falls self-efficacy, social support and enjoyment of physical activity are not much studied, as well as if the correlates differ with regard to disease severity. The aim of the study was to examine associations between physical activity and age, gender, employment, having children living at home, education, disease type, disease severity, fatigue, self-efficacy for physical activity, falls self-efficacy, social support and enjoyment of physical activity in a sample of persons with MS and in subgroups with regard to disease severity.Methods: This is a cross-sectional survey study including Swedish community living adults with MS, 287 persons, response rate 58.2%. The survey included standardized self-reported scales measuring physical activity, disease severity, fatigue, self-efficacy for physical activity, falls self-efficacy, and social support. Physical activity was measured by the Physical Activity Disability Survey – Revised.Results: Multiple regression analyzes showed that 59% (F(6,3)=64.9, p=0.000) of the variation in physical activity was explained by having less severe disease (β=-0.30), being employed (β=0.26), having high falls self-efficacy (β=0.20), having high self-efficacy for physical activity (β=0.17), and enjoying physical activity (β=0.11). In persons with moderate/severe MS, self-efficacy for physical activity explained physical activity.Conclusions: Consistent with previous research in persons with MS in other countries this study shows that disease severity, employment and self-efficacy for physical activity are important for physical activity. Additional important factors were falls self-efficacy and enjoyment. More research is needed to confirm this and the subgroup differences.

- PURPOSE: The purpose was to evaluate the psychometric properties of physical activity measures in persons with multiple sclerosis (PwMS).METHODS: Adults with multiple sclerosis were recruited, n = 30 (validation) and n = 57 (test-retest). Steps measured with PiezoRX, Yamax SW200 and ActiGraph GT9X Link (AGlink) and time in different positions measured with AGlink were validated against data from video analysis. Psychometric properties of the Physical Activity and Disability Survey - Revised Swedish version (PADS-R(Sw)) was evaluated.RESULTS: The most valid measures were AGlink using the low-frequency extension filter, and PiezoRX with median absolute percentage errors (MeAPEs) of 0.9-3.1% and 1.3-3.3%. The MeAPEs were higher for Yamax SW200 (2.9-21.0%), AGlink display (3.6-44.8%) and AGlink normal filter (8.9-48.9%), indicating low validity. AGlink was not valid in measurements of sitting (MeAPE 12.0-12.5%) or lying (MeAPE 31.0-41.7%). The correlation between PADS-R(Sw) and AGlink steps was r = 0.492 (p = .009). The relative reliability of PADS-R(Sw) was ICC2,1 0.85 (CI 0.76-0.91), and absolute reliability was SEM 0.54.CONCLUSION: AGlink and PiezoRX were valid measures of steps in PwMS. The questionnaire PADS-R(Sw) was valid, with high relative reliability, but its absolute reliability was unsatisfactory.

- Clinical differentiation between parkinsonian syndromes (PS) remains a challenge despite well-established clinical diagnostic criteria. Specific diagnostic biomarkers have yet to be identified, though in recent years, studies have been published on the aid of certain brain related proteins (BRP) in the diagnosing of PS. We investigated the levels of the light subunit of neurofilament triplet protein (NF-L), total tau and phosphorylated tau, amyloid-β(1-42), and the soluble α- and β-cleaved fragments of amyloid precursor proteins in a cohort of patients with various PS.
