- Background: If localised pain represent one end of a pain spectra, with overall better general health, chronic widespread pain (CWP) and fibromyalgia represent the other end of the spectra with worse general health and more comorbidities with other somatic diseases and mental illness. Sleep problems and fatigue are common among individuals reporting CWP and previous research indicate that sleep problems may be an important predictor for pain prognosis.Objectives: The aim of this population-based study was to investigate if sleep problems and fatigue predict the onset of CWP 5 and 18 years later.Methods: In order to get more stable baseline classifications of CWP, a wash-out period was used, including only individuals who had not reported CWP (according to ACR 1990 criteria for fibromyalgia) at baseline (−98) and three years prior baseline (−95). In all, data from 1249 individuals entered the analyses for the 5 year follow-up (−03) and 791 entered for the 18 year follow-up (−16). Four parameters related to sleep (difficulties initiating sleep, maintaining sleep, early morning awakening and non-restorative sleep), and one parameter related to fatigue (SF-36 vitality scale) were investigated as predictors for CWP. Binary logistic regression analysis were used for analyses.Results: All investigated parameters predicted the onset of CWP five years later (problems with initiating sleep (OR 1.91; 1.16–3.14), maintaining sleep (OR 1.85; 1.14–3.01), early awakening (OR 2.0; 1.37–3.75), non-restorative sleep (OR 2.27; 1.37–3.75) and fatigue (OR 3.70; 1.76–7.84)) in a model adjusted for age, gender, socio-economy and mental health. All parameters except problems with early awakening predicted the onset of CWP also 18 years later. In all, 785 individuals did not report any of the sleeping problems at baseline (fatigue not included), 268 reported one of the problems, 167 two, 128 three and 117 subjects reported to have all four sleep problems. Reporting all four sleep problems was significantly associated with CWP at follow-up at both time points when adjusting for age, gender, socio economy and mental health (OR 4.00; 2.03–7.91 and OR 3.95; 1.90–8.20); adjusting for age, gender, socio economy and number of pain regions (OR 2.94; 1.48–5.82 and OR 2.65; 1.24–5.64) and in a model adjusting for age, gender, socio economy and pain severity (OR 2.97;1.53–5.76; and OR 3.02;1.47–6.21) for the 5 year and 18 year follow-up respectively, compared to not reporting any of the sleep problems at baseline.Conclusions: Both sleeping problems and fatigue predicts the onset of CWP 5- and 18 years later. The results highlight the importance of the assessment of sleep quality in the clinic.

- BackgroundPrevious research suggests that sleep problems may be an important predictor for chronic widespread pain (CWP). With this study we investigated both sleep problems and fatigue as predictors for the onset of CWP over a 5-year and an 18-year perspective in a population free from CWP at baseline.MethodsTo get a more stable classification of CWP, we used a wash-out period, including only individuals who had not reported CWP at baseline (1998) and three years prior baseline (1995). In all, data from 1249 individuals entered the analyses for the 5-year follow-up and 791 entered for the 18-year follow-up. Difficulties initiating sleep, maintaining sleep, early morning awakening, non-restorative sleep and fatigue were investigated as predictors separately and simultaneously in binary logistic regression analyses.ResultsThe results showed that problems with initiating sleep, maintaining sleep, early awakening and non-restorative sleep predicted the onset of CWP over a 5-year (OR 1.85 to OR 2.27) and 18-year (OR 1.54 to OR 2.25) perspective irrespective of mental health (assessed by SF-36) at baseline. Also fatigue predicted the onset of CWP over the two-time perspectives (OR 3.70 and OR 2.36 respectively) when adjusting for mental health. Overall the effect of the sleep problems and fatigue on new onset CWP (over a 5-year perspective) was somewhat attenuated when adjusting for pain at baseline but remained significant for problems with early awakening, non-restorative sleep and fatigue. Problems with maintaining sleep predicted CWP 18years later irrespective of mental health and number of pain regions (OR 1.72). Reporting simultaneous problems with all four aspects of sleep was associated with the onset of CWP over a five-year and 18-yearperspective, irrespective of age, gender, socio economy, mental health and pain at baseline. Sleep problems and fatigue predicted the onset of CWP five years later irrespective of each other.ConclusionSleep problems and fatigue were both important predictors for the onset of CWP over a five-year perspective. Sleep problems was a stronger predictor in a longer time-perspective. The results highlight the importance of the assessment of sleep quality and fatigue in the clinic.

Tidskriftsartikel (refereegranskat)abstract
- Background: Fatigue, pain, stiffness and impaired physical function are some of the most pronounced symptoms in rheumatoid arthritis (RA) that may affect quality of life. Quality of life is an individual experience composed of a wide range of factors, including physical health, psychological state, level of independence, social relationships, and the patients' relationship to salient features of their environment. There is a need to describe and assess quality of life in chronic diseases like established RA. Previous research has mainly focused on disease-specific instruments for assessing quality of life. A deeper understanding of patients' experience of quality of life in established RA is important in both clinical research and daily clinical practice.Objectives: To describe variations in patients' experiences of quality of life in established RA.Methods: The study had a qualitative design with a phenomenographic approach, including 22 interviews with patients from the Swedish BARFOT (Better Anti-Rheumatic FarmacoTherapy) cohort, BARFOT, a long time follow up study of early RA. Patients were strategically selected by gender (14 women and 8 men), age (30 to 84 years old), disease duration (8–23 years), function as measured by HAQ (0–1.38), and quality of life as measured by EQ5D (0.52–1.00). The interviews were recorded, transcribed verbatim and coded into categories.Results: Four categories emerged from the patients' experiences of quality of life in established RA: well-being, freedom, empowerment, and participation. Quality of life as well-being meant pleasure and being physical active. Quality of life as freedom meant dependence or independence in the ability to manage daily life activities. Quality of life as empowerment meant different coping strategies, such as positive thinking and resources to manage fatigue, pain and physical function. Quality of life as participation meant togetherness in different contexts with other people.Conclusions: Quality of life in established RA could be understood by the patients in different ways. The patients experienced quality of life as well-being, freedom, empowerment, and participation. This is important knowledge when evaluating the concept of quality of life in RA research, and for health professionals when promoting quality of life in patients with RA.

- Background: Fatigue, pain, stiffness, impaired muscle function and impaired physical function are some of the most pronounced symptoms in rheumatoid arthritis (RA) and these may be related to lifestyle habits such as physical activity, diet, smoking and alcohol.There is limited knowledge about how patient with longstanding RA understand their lifestyles habits in relation to their disease and quality of life.Objectives: To describe experiences of how lifestyle habits relate to quality of life in patients with longstanding RA. Methods: A qualitative study with a deductive content analysis design, including 17 patients from the Swedish BARFOT (Better Anti-Rheumatic FarmacoTherapy) cohort. BARFOT is a long time follow up study of early RA. Informants were strategically selected by gender (ten women and seven men), age (range 30-84 years), disease duration (8-23 years), function as measured by HAQ, and quality of life as measured by EQ5D. Semi-structured interviews focused on four lifestyle habits (main categories); Physical activity, Diet, Smoking, and Alcohol. The interviews were recorded, transcribed verbatim and coded into subcategories within each of the four main categories.Results: In patients with longstanding RA quality of life was related to the four given main categories (lifestyle habits). Each main category included two to three subcategories; (1) Physical activity means barrier, opportunities and well-being, (2) Diet means shame, well-being and social relationship, (3) Smoking means reward and fear, and (4) Alcohol means ambivalence and social relationship.Conclusions: In longstanding RA, lifestyle habits relates to quality of life through both positive and negative experiences. This has to be taken into account in clinical care for a better understanding of how patients conceive and adherer to advice on lifestyle.References: Scott DL, Wolfe F, Huizinga TW.

Pressure pain thresholds and the associations with chronic widespread pain, knee osteoarthritis and obesity in individuals with knee pain
- 2020
-
Konferensbidrag (refereegranskat)abstract
- Approximate 30% of individuals with symptomatic knee osteoarthritis (OA) had developed chronic widespread pain (CWP) over a period of 20 years [1]. In order to prevent CWP in those with knee pain, it is important to study associated factors.Objectives:The aim was to study pressure pain thresholds among individuals with knee pain with or without radiographic changes, and associations with CWP, radiographic knee OA, and obesity.Methods:Out of 300 individuals with knee pain (with or without radiographic changes) from an ongoing longitudinal study, 279 conducted pressure pain thresholds (PPT) measurement at baseline in this cross-sectional study (71% women; mean age 51 years). The PPT were measured using a computerized pressure algometry on eight predefined tender points (Figure 1) out of the 18 points as part of the definition of fibromyalgia [2]. PPTs were dichotomised based on the lowest tertial vs the two higher tertials for each of the eight points. A group that had ≥4 points with low PPT (low PPT group) was compared to a group that had <4 low PPT (not low PPT group). A pain mannequin categorised the participants in three different pain groups: CWP, chronic regional pain (CRP), and no chronic pain (NCP) according to the definition of the ACR [2]. Radiographic knee OA was defined according to the Ahlbäck five grading scale as having score ≥1 vs score 0 [3]. Obesity was measured by bioimpedance measuring BMI and visceral fat area (VFA, cm2). To study associations, a crude logistic regression model controlled for age and sex was used including main and significant variablesFigure 1Differences in mean PPT in the eight tender pointsResults:The prevalence of CWP was 37% and higher in the low PPT group compared to those in the not low PPT group (Table 1). No differences were found between the groups in BMI, VFA or radiographic knee OA (Table 1). The low PPT group had significantly lower mean PPT on all eight tender points, was younger, had more pain sites, and more cases of fibromyalgia compared to the group with not low PPT (Table 1, Figure 1). Age (OR 0.95; 95% CI 0.92–0.97), having CWP (OR 3.00; CI 1.66–5.06), fibromyalgia (OR 21.91; CI 2.45–194.69) and increased number of pain sites (OR 1.13; CI 1.05–1.22) were associated with low PPT.Table 1.Descriptive statistics for the whole sample and for the groups: low PPT and not low PPTAlln = 279Low PPTn = 99Not low PPTn = 180p-valueAge, mean years (sd)51 (9)49 (9)53 (8)<0.001Women, n (%)197 (71%)69 (70%)128 (71%)0.804Pain group, n (%)<0.001 NCP/CRP160 (63%)41 (47%)119 (71%) CWP95 (37%)46 (53%)49 (29%)Numbers of pain sites, mean (sd)5 (4)6 (5)4 (3)0.003Fibromyalgia, n (%)8 (3%)7 (9%)1 (1%)0.001Knee OA Ahlbäck, n (%)59 (23%)16 (18%)43 (26%)0.132BMI, n (%)127 (48%)42 (47%)85 (48%)0.801 Normal Overweight/Obese139 (52%)48 (53%)91 (52%)VFA, mean cm2(sd)114 (54)115 (51)113 (55)0.788Conclusion:Baseline characteristics of individuals with knee pain showed a higher prevalence of CWP than in the general population [4]. In the group with low PPT, the prevalence was even higher. The study found associations between CWP and low PPT, however, almost half of the individuals with low PPT reported NCP/CRP. Moreover, a third in the group that not had low PPT reported CWP. The development of widespread pain in individuals with knee pain needs to be further studied over time to increase the knowledge of CWP’s origin in order to prevent the condition.References:[1]Bergman et al.

- BackgroundKnee osteoarthritis (KOA), chronic widespread pain (CWP) and overweight/obesity are public health problems that often coincide, and there is a multifactorial and unclear relationship between them. The study aimed to (1) investigate pain sensitivity, assessed by pressure pain thresholds (PPTs), among women and men with knee pain and (2) associations with, respectively, radiographic KOA (rKOA), CWP, and overweight/obesity.MethodsBaseline data from an ongoing longitudinal study involving 280 individuals with knee pain in the 30-60 age group. Pain sensitivity was assessed by PPTs on eight different tender points using a pressure algometer. The participants' knees were x-rayed. Self-reported CWP and number of pain sites were assessed with a pain figure, and overweight/obesity was measured using body mass index (BMI), visceral fat area (VFA), and body fat percentage, assessed with a bioimpedance. Associations were analysed using regression analyses.ResultsWomen reported lower PPTs than men (p<0.001), but no PPTs differences were found between those with and without rKOA. Low PPTs was associated with female sex, more pain sites, CWP, and a higher VFA and body fat percentage. The tender points second rib and the knees were most affected. The prevalence of CWP was 38%.ConclusionsThe modifiable factors, increased VFA, and body fat could be associated with increased pain sensitivity among individuals with knee pain. Longitudinal studies are needed to further investigate the associations.

- In contrast to animal and fungal cells, green plant cells contain one or multiple chloroplasts, the organelle(s) in which photosynthetic reactions take place. Chloroplasts are believed to have originated from an endosymbiotic event and contain DNA that codes for some of their proteins. Most chloroplast proteins are encoded by the nuclear genome and imported with the help of sorting signals that are intrinsic parts of the polypeptides. Here, we show that a chloroplast-located protein in higher plants takes an alternative route through the secretory pathway, and becomes N-glycosylated before entering the chloroplast.

- Background: Chronic widespread pain (CWP) is a common condition (approximately 10% prevalence), that affects women twice as often as men. There is a lack of knowledge in how different coping strategies relates to health status during CWP development in a general population.Objectives: To explore different ways of coping with CWP and to relate the different coping strategies to health-related factors, before and after developing CWP.Methods: A sequential explorative mixed methods study including 19 women 45-67 of age, who had reported CWP in a survey 2016, but not in 1995. Individual interviews were analysed with a phenomenographic approach, and resulted in four categories of coping strategies. These categories were further explored with regard to four dimensions of health status (physical function, bodily pain, vitality and mental health) as measured by SF-36 (0-100, a lower score indicates more disability) and sleep problems measured both in 1995, and 2016.Results: The qualitative analysis revealed four categories representing different coping strategies, where each woman was labelled by the most dominant category; the mastering woman, the persistent woman, the compliant woman and the conquered woman. The first two categories emerged as being active coping strategies, and the latter two as passive. Women with passive strategies reported significantly lower vitality (median 57.5 vs 75, p=0.007) and worse mental health (median 54 vs 93, p=0.021) in 1995, before they had developed CWP compared with those with active coping strategies. No differences were seen between the groups on physical function, bodily pain or sleep.In 2016, there were still a difference between the passive and active group regarding mental health (median 56 vs 80, p=0.022), but not for vitality (median 35 vs 40, p=0.707). No differences were seen between the groups on physical function or bodily pain. All eight women with passive strategies reported problems with sleep in 2016, as compared to 6 of the 11 women with active strategies (p=0.045).Conclusion: Women that reported CWP in 2016, but not in 1995, described both active and passive coping strategies. The qualitative findings were associated with differences in vitality and mental health already in 1995, before they had developed CWP. Further, those with passive coping strategies reported worse health with regard to mental health and sleep problems in 2016. Interestingly, the groups did not differ in bodily pain or physical function neither in 1995 nor in 2016, which implicates the importance for the clinician to take the typical coping strategy into consideration, when meeting these patients in clinical settings. © Aili, Bergman, Bremander, Haglund & Larsson 2019.

Tidskriftsartikel (refereegranskat)abstract
- Background: Approximately ten percent of the population report chronic widespread pain (CWP), the condition is more common among women than men. For most people, the pain interferes with many aspects of every-day life and implies large consequences. However, the group reporting CWP is heterogeneous and there is a need for better understanding of the different strategies used for coping with pain in every-day life.Objectives: The purpose of this study was to describe women’s experiences of how to cope with CWP.Methods: The study had a descriptive design with a qualitative content analysis approach. Individual interviews were conducted with 19 women, 31–66 of age, who had reported CWP in a survey 2016. CWP was defined according to the 1990 ACR criteria for fibromyalgia. To be considered chronic, the pain should have persisted for more than three months during the last 12 months. A manifest qualitative content analysis was used to analyze the main question “How do you cope with your chronic widespread pain?” The analysis resulted in four categories.Results: Women described their coping with CWP in four different ways; to take control, to continue as usual, to follow instructions and to rest. To take control meant to make deliberate decisions to handle everyday day life. It also meant to take care of oneself, to think positive and to exercise at an adequate level. To continue as usual meant not to listen to body signals and either to ignore or accept the pain. To follow instructions meant listening to the health professionals and following advices, but without taking any part of the responsibility for the treatment outcome. To rest meant to perceive an unreasonable need for recovery, to resign and let the pain set the terms for the daily living.Conclusions: Women expressed different ways of coping with CWP including both active and passive strategies. The coping strategies included two dimensions, where one ranged from actively taking control over the pain, to passively following instructions and the other from actively continue as usual by either accepting or ignoring the pain to passively rest and being mastered by pain.
