- Background: Chronic musculoskeletal pain is common in adolescents, and it has been shown that adolescents with pain may become young adults with pain. Pain often coincides with psychosomatic symptoms in adults, but little is known about longitudinal associations and predictors of pain in adolescents. The aim was to investigate chronic musculoskeletal pain and its associations with health status, sleeping problems, stress, anxiety, depression, and physical activity in 16-year-old students at baseline, and to identify risk factors using a three-year follow-up. Methods: This was a longitudinal study of 256 students attending a Swedish upper secondary school. Questionnaires regarding chronic musculoskeletal pain and distribution of pain (mannequin), health status (EQ-5D3 L), sleeping problems (Uppsala Sleep Inventory), stress symptoms (single-item question), anxiety and depression (Hospital Anxiety and Depression Scale), and physical activity (International Physical Activity Questionnaire) were issued at baseline and follow-up. Student's t-test and chi2 test were used for descriptive statistics and logistic regression analyses were used to study associations between chronic pain and independent variables. Results: Fifty-two out of 221 students at baseline (23.5%) and 39 out of 154 students at follow-up (25.3%) were categorized as having chronic musculoskeletal pain. Chronic musculoskeletal pain at follow-up was separately associated with reporting of an EQ-5D value below median (OR 4.06, 95% CI 1.83-9.01), severe sleeping problems (OR 3.63, 95% CI 1.69-7.82), and possible anxiety (OR 4.19, 95% CI 1.74-10.11) or probable anxiety (OR 3.82, 95% CI 1.17-12.48) at baseline. Similar results were found for associations between chronic musculoskeletal pain and independent variables at baseline. In multiple logistic regression analysis, chronic musculoskeletal pain at baseline was a predictor of chronic musculoskeletal pain at follow-up (OR 2.99, 95% CI 1.09-8.24, R-2 = 0.240). Conclusion: Chronic musculoskeletal pain at baseline was the most important predictor for reporting chronic musculoskeletal pain at the three-year follow-up, but a worse health status, severe sleeping problems, and anxiety also predicted persistence or development of chronic musculoskeletal pain over time. Interventions should be introduced early on by the school health services to promote student health.

Tidskriftsartikel (övrigt vetenskapligt/konstnärligt)abstract
- Background: The relationship between chronic multisite musculoskeletal pain (CMP) and sleep is complex, where pain can lead to sleeping problems and lack of sleep can intensify the pain perception. Most previous studies relates to adults, but adolescents may also suffer from CMP, and there is a need for more knowledge regarding the relationships between CMP and sleeping problems, stress, anxiety, depression, and health status.Objectives: To study background factors associated to CMP in first year Swedish high school students.Methods: First year Swedish high school students (n=296) were invited to complete questionnaires on chronic pain (mannequin with 18 body regions), sleeping problems (Uppsala Sleep Inventory, four items scored from 1–5), stress (ELO questions, scored from 1–5), anxiety and depression (Hospital Anxiety and Depression Scale, scored from 0–21), health status (EQ-5D, scored from 0 to 1, worst to best) and physical activity (International Physical Activity Questionnaire, categorised into low, moderate and high levels). Stress and sleeping items were dichotomized into 1–3 points (best) vs 4–5 points (worst). Individuals scoring at least severe problems (4 points) at one or more sleeping items were classified as having severe sleeping problems. HADS were categorised as non-cases (0–7), possible7–10 and probable cases (11–21 points). Students were grouped as having CMP (pain present in ≥3 regions) or not (no chronic pain or chronic pain in 1–2 regions). Multiple logistic regression analyses (adjusted for sex) with CMP as dependent variable were performed in SPSS, version 24.Results: 254 students (86% of total sample, 87 boys and 167 girls) with a mean age of 16.1 (SD 0.6) years participated in the study. CMP was present in 25 (9.8%) students with no differences between boys and girls (8.0% vs 10.8%; p=0.488). Having CMP was associated with reporting severe sleeping problems (OR 2.49, 95% CI: 1.06 to 5.81, p=0.035) with initiating sleep, maintaining sleep, early morning awakenings and/or not feeling restored after sleep in comparison to the other students. Students with CMP were more likely to be categorised as probable cases for anxiety (OR 3.06, 95% CI: 1.09 to 8.61, p=0.034), but there were no associations for possible cases for anxiety (OR 1.15, 95% CI: 0.38 to 3.51, p=0.800), possible cases (OR 2.03, 95% CI: 0.63 to 6.54), or probable cases for depression (OR 3.35, 95% CI: 0.33 to 33.83). There was a nearly significant association between stress and belonging to the CMP group (OR 2.31, 95% CI: 0.97 to 5.53, p=0.059). A higher self-reported health status was associated to a lower likelihood for CMP (OR 0.04, 95% CI: 0.01 to 0.27, p=0.001). Distribution of physical activity levels of low, moderate and high was not significantly associated to having CMP in comparison with not having it.Conclusions: One in ten high school students fulfilled criteria for having chronic multisite musculoskeletal pain. CMP was associated to sleeping problems, anxiety, and a worse health status. The results from this study may be used by school health-care professionals in their preventive work to promote student’s health.Disclosure of Interest: None declared

Mass spectrometry in peptide and tumor marker analysis
- 1999

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Integration of preparative protein and peptide separations with analytical techniques, in particular mass spectrometry (MS), is important. This thesis describes preparation via capillary electrophoresis and two-dimensional (2-D) gel electrophoresis for identification and structure determination of polypeptides. Protocols for protein identification via mass spectrometry were developed. Applications in sequence determination of peptides and in screening of proteins extracted from solid tumor material were tested. Preparative capillary electrophoresis of peptide samples and subsequent characterization of fractionated material with matrix-assisted laser desorption ionization (MALDI)-MS is feasible provided the same electrolyte is not used for both separation and collection because of a risk for signal suppression in the mass analysis. To avoid suppression, separate electrolytes were used, phosphate buffer for good resolution in the separations and trifluoroacetic acid for improved signal to-noise ratio and resolution of sodium adducts in the mass analysis. To increase the preparative capacity in capillary electrophoresis and to prevent wall adsorption and band-broadening, a low amount of ethylene glycol was used in both sample and buffers. C-terminal sequence analysis of peptides was carried out using a mixture of two carboxypeptidases, CPP and CPY. The resulting amino acid sequence was determined via MALDI-MS. To distinguish Lys from Gln, which have similar mass, Lys was derivatized to homoarginine. For ladder sequencing of peptides containing Cys, this amino acid was converted to 4-tialaminine. The protein expression patterns of oncogene-transformed cell lines and tumor cells of different malignancies from breast, lung and ovary were analyzed by 2-D gel electrophoresis. The purpose was to find proteins which can be of potential use as tumor markers. Different protocols were tested for isolation of the protein fragments from the gel matrix. In-gel digestion using modified trypsin with extensive washings to remove salts and detergents was essential, together with precautions to avoid introduction of keratin contaminants and polymers. Both MALDI-MS and ion-trap LC (liquid chromatography)-MS/MS were applied for identification of gel-separated proteins. In general, MALDI-MS is more sensitive than ESI (electrospray ionization)-MS, less affected by contaminants and can serve as a first screening step as several samples can be analyzed sequentially. LC on line with ESI-MS means sample clean-up before analysis of separate peptide components. This set-up is possible to automatize and suppression is reduced, which both are advantages in relation to nanospray technology.

Tidskriftsartikel (refereegranskat)abstract
- BackgroundDuring the pandemic, increased numbers of patients requiring intensive care unit (ICU) admission required an increase in ICU capacity, including ICU staffing with competence to care for critically ill patients. Consequently, nurses from acute care areas were called in to staff the ICU along with experienced intensive care nurses.Aims and objectivesTo describe Swedish registered nurses' experiences of caring for patients with COVID-19 in ICUs during the pandemic.DesignMixed method survey design.MethodsAn online questionnaire was distributed through social media to registered nurses who had been working in the ICU during the COVID-19 outbreak. Data were collected for 1 week (May 2020) and analysed using content analysis and descriptive statistics.ResultsOf the 282 nurses who participated, the majority were ICU nurses (n = 151; 54%). Half of the nurses specialized in ICU reported that they were responsible for the ICU care of three or more patients during the pandemic (n = 75; 50%). Among non-intensive care nurses, only 19% received introduction to the COVID-19 ICU (n = 26). The analysis of data regarding nurses' experiences resulted in three categories: tumbling into chaos, diminished nursing care, and transition into pandemic ICU care. Participants described how patient safety and care quality were compromised, and that nursing care was severely deprioritized during the pandemic. The situation of not being able to provide nursing care resulted in ethical stress. Furthermore, an increased workload and worsened work environment affected nurses' health and well-being.ConclusionsThe findings from the present study indicate that nurses perceived that patient safety and quality of care were compromised during the pandemic. This resulted in ethical stress among nurses, which may have affected their physical and psychosocial well-being.Relevance to clinical practiceThe COVID-19 pandemic had a severe impact on nurses' work environment, which could result in burnout and staff turnover.

- Background: To explore the relationships between anaemia or iron deficiency (ID) and symptoms, quality of life (QoL), morbidity, and mortality.Methods: A post-hoc, non-prespecified, explorative substudy of the prospective randomized PREFER trial. One centre study of outpatients with severe HF and palliative need managed with advanced home care. Associations between anaemia, ID, and the Edmonton Symptom Assessment Scale (ESAS), Euro QoL (EQ-5D), Kansas City Cardiomyopathy Questions (KCCQ) were examined only at baseline but at 6months for morbidity and mortality.Results: Seventy-two patients (51 males, 21 females), aged 79.2±9.1years. Thirty-nine patients (54%) had anaemia and 34 had ID (47%). Anaemia was correlated to depression (r=0.37; p=0.001), anxiety (r=0.25; p=0.04), and reduced well-being (r=0.26; p=0.03) in the ESAS; mobility (r=0.33; p=0.005), pain/discomfort (r=0.27; p=0.02), and visual analogue scale of health state (r=-0.28; p=0.02) in the EQ-5D; and physical limitation (r=-0.27; p=0.02), symptom stability; (r=-0.43; p<0.001); (r=-0.25; p=0.033), social limitation;(r=-0.26; p=0.03), overall summary score; (r=-0.24, p=0.046) and clinical summary score; (r=-0.27; p=0.02) in the KCCQ. ID did not correlate to any assessment item. Anaemia was univariably associated with any hospitalization (OR: 3.0; CI: 1.05-8.50, p=0.04), but not to mortality. ID was not significantly associated with any hospitalization or mortality.Conclusion: Anaemia, but not ID, was associated although weakly with symptoms and QoL in patients with advanced HF and palliative home care.

Tidskriftsartikel (refereegranskat)abstract
- Background: A new biomarker, suppression of tumorigenicity 2 (ST2) has been introduced as a marker for fibrosis and hypertrophy. Its clinical value in comparison with N-terminal pro-hormone of brain natriuretic peptide /Amino-terminal pro-B-type natriuretic peptide (NTproBNP) in predicting mortality in elderly patients with symptoms of heart failure (HF) is still unclear.Aim: To evaluate the prognostic value for all-cause- and cardiovascular mortality of ST2 or NTproBNP and the combination of these biomarkers.Patients and methods: One hundred seventy patients patients with clinical symptoms of HF (77 (45%) were with verified HF) were recruited from one selected primary health care center (PHC) in Sweden and echocardiography was performed in all patients. Blood samples were obtained from 159 patients and stored frozen at -70 degrees C. NTproBNP was analyzed at a central core laboratory using a clinically available immunoassay. ST2 was analyzed with Critical Diagnostics Presage ST2 ELISA immunoassay.Results: We studied 159 patients (mean age 778.3years, 70% women). During ten years of follow up 78 patients had died, out of which 50 deaths were for cardiovascular reasons. Continuous NTproBNP and ST2 were both significantly associated with all-cause mortality (1.0001; 1.00001-1.0002, p=0.04 and 1.03; 1.003-1.06, p=0.03), NTproBNP but not ST2 remained significant for cardiovascular mortality after adjustments (1.0001; 1.00001-1.0002, p=0.03 and 1.01; 0.77-1.06, p=0.53), respectively. NTproBNP above median (>328ng/L) compared to below median was significantly associated with all-cause mortality(HR: 4.0; CI :2.46-6.61; p<0.001) and cardiovascular mortality (HR: 6.1; CI: 3.11-11.95; p<0.001). Corresponding analysis for ST2 above median (25.6ng/L) was not significantly associated neither with all-cause mortality (HR; 1.4; CI: 0.89-2.77) nor cardiovascular mortality (HR: 1.3; CI: 0.73-2.23) and no significant interaction of NTproBNP and ST2 (OR: 1.1; CI: 0.42-3.12) was found.Conclusion: In elderly patients with symptoms of heart failure ST2 was not superior to NTproBNP to predict all cause or cardiovascular mortality. Furthermore, it is unclear if the combination of ST2 and NTproBNP will improve long-term prognostication beyond what is achieved by NTproBNP alone.

Tidskriftsartikel (refereegranskat)abstract
- Psoriasis is a disease with considerable heterogeneity in clinical presentation. This is the first study using two-dimensional gel electrophoresis to compare global protein expression patterns in lesional and non-lesional skin from subjects with acute guttate psoriasis associated with streptococcal throat infection and chronic plaque psoriasis. Samples from experimentally induced contact eczema and normal skin from healthy controls were also included. Proteins with statistically significant differences in expression were used in hierarchical cluster analyses resulting in separation of the different samples into groups. Chronic plaque and guttate psoriasis samples were distinctly separated, indicating that they represent discrete phenotypes at the protein expression level. Interestingly, there was a trend in which guttate psoriasis lesions clustered closer to eczema than to chronic plaque psoriasis lesions, indicating that the duration of the inflammatory reaction may affect clustering. Several of the differentially expressed proteins were identified by mass spectrometry.

BDNF Responses in Healthy Older Persons to 35 Minutes of Physical Exercise, Cognitive Training, and Mindfulness : Associations with Working Memory Function

Tidskriftsartikel (refereegranskat)abstract
- Brain-derived neurotrophic factor (BDNF) has a central role in brain plasticity by mediating changes in cortical thickness and synaptic density in response to physical activity and environmental enrichment. Previous studies suggest that physical exercise can augment BDNF levels, both in serum and the brain, but no other study has examined how different types of activities compare with physical exercise in their ability to affect BDNF levels. By using a balanced cross over experimental design, we exposed nineteen healthy older adults to 35-minute sessions of physical exercise, cognitive training, and mindfulness practice, and compared the resulting changes in mature BDNF levels between the three activities. We show that a single bout of physical exercise has significantly larger impact on serum BDNF levels than either cognitive training or mindfulness practice in the same persons. This is the first study on immediate BDNF effects of physical activity in older healthy humans and also the first study to demonstrate an association between serum BDNF responsivity to acute physical exercise and working memory function. We conclude that the BDNF increase we found after physical exercise more probably has a peripheral than a central origin, but that the association between post-intervention BDNF levels and cognitive function could have implications for BDNF responsivity in serum as a potential marker of cognitive health.

- Six individuals with experience of psychosis were interviewed about their psychotic experiences. The material was analyzed using the empirical phenomenological psychological method. The results consist of a whole meaning structure, a gestalt, entailing the following characteristics: The feeling of estrangement in relationship to the world; the dissolution of time; the loss of intuitive social knowledge; the alienation of oneself, and finally; the loss of intentionality/loss of agency. In brief, the results show that an altered perception of the self and the world was an essential part of the psychotic experience where subjects described themselves as changed; something was sensed as being wrong as psychosis is perceptible but hard to communicate. The normal life-world experience was altered and reality seemed strange. Time perception seemed to be changed as temporality appeared dissolved and the experience of time was focused on the current moment excluding the future. The subjects described loss of intentionality, they were no longer agents in their actions but partly steered by others and they could feel as if their experiences were not theirs. The patients also describe problems regarding their ability to socialize and communicate with others. They seem to lose their intuitive social capacity and were prone to suspiciousness.

Daily Musculoskeletal Pain Affects Health And Sports Performance Negatively In Youth Athletes
- 2017

Tidskriftsartikel (refereegranskat)abstract
- In sports, musculoskeletal pain (MSP) is often studied from the perspective of sport specific injuries, why little is known about the prevalence of daily or multisite MSP that does not affect participation in sports. It is also unclear if daily or multisite MSP is a risk factor for worse health-related quality of life (HRQoL) and worse sports performance in youth athletes.PURPOSE: To study how HRQoL and sports performance is affected by daily MSP in youth athletes that are able to participate in sports.METHODS: 136 Swedish youth athletes attending a sport school (13 to 14 years, boys n=83, girls n=53) completed the EQ-5D measuring HRQoL (range 0 to 1, worst to best), a pain questionnaire including current pain (yes/no), pain in 18 body regions (never to rarely/monthly to weekly/more than once a week to almost daily), and pain intensity in the last week (0 to 10, best to worst), anthropometric measures to estimate biological age, and sports performance tests (grip strength, 20 meter sprint, and countermovement jump(CMJ)).RESULTS: 109 to 117 of the 136 students answered the different pain questions. 53 of 113 (47%) reported current MSP, and 28 of 109 (26%) experienced MSP ‘more than once a week to almost daily’ from one or more body regions (frequent MSP group), while 28% (n=30) stated ‘never to rarely’ in MSP (no MSP group). Boys in the frequent MSP group reported worse HRQoL, higher pain intensity, performed worse in all sports performance tests, and had a younger biological age than boys in the no MSP group. Girls in the frequent MSP group reported worse HRQoL and higher pain intensity than the girls in the no MSP group. No other differences were found (table).CONCLUSIONS: Every other youth athlete attending a sport school reported current MSP and one out of four reported almost daily MSP. MSP affects HRQoL negatively in both boys and girls, and sports performance negatively in boys. The prevalence of MSP in youth athletes is concerning since pain in younger ages may predict pain in adult ages.© 2017 American College of Sports Medicine
