- We determined the efficacy of a back muscle extensor strengthening program on the back muscle extensor strength, kyphosis, height and thoracic expansion in women with at least one vertebral fracture, kyphosis and osteoporosis. Thirty-six patients were included and randomized to a control or a training group. The training focused on back muscle extensor strengthening program for 1 h, twice a week for 4 months and was performed by a physiotherapist. The main outcome measure was the back muscle extensor strength. In an intention-to-treat analysis no significant effects on back muscle strength in the training group vs. controls could be seen (p = 0.74). In a per-protocol analysis (n = 28), the training group increased back muscle strength from 290 ± 87 to 331 ± 89 N while the control group showed no improvement. After adjusting for the strength at baseline, a significant effect of training could be demonstrated (p = 0.029). When comparing the heights between the groups a significant group × time interaction was observed (p = 0.012) where the training women increased their mean height with 0.3 cm (p = 0.101) and controls decreased 0.44 cm (p = 0.045). The training group improved their thoracic expansion compared with baseline (p = 0.03). No effect of training on kyphosis was seen. In conclusion, a 4-months back extensor training program can improve back strength and seems to maintain height and thoracic expansion.

Tidskriftsartikel (refereegranskat)abstract
- Background: Pelvic girdle pain (PGP) in pregnancy is distinct from pregnancy-related low back pain (PLBP). However, women with combined PLBP and PGP report more serious consequences in terms of health and function. PGP has been estimated to affect about half of pregnant women, where 25% experience serious pain and 8% experience severe disability. To date there are relatively few studies regarding persistent PLBP/PGP postpartum of more than 3 months, thus the main objective was to identify the prevalence of persistent PLBP and PGP as well as the differences over time in regard to pain status, self-rated health (SRH) and family situation at 12 months postpartum. Methods: The study is a 12 month follow-up of a cohort of pregnant women developing PLBP and PGP during pregnancy, and who experienced persistent pain at 6 month follow-up after pregnancy. Women reporting PLBP/PGP (n = 639) during pregnancy were followed up with a second questionnaire at approximately six month after delivery. Women reporting recurrent or persistent LBP/PGP at the second questionnaire (n = 200) were sent a third questionnaire at 12 month postpartum. Results: A total of 176 women responded to the questionnaire. Thirty-four women (19.3%) reported remission of LBP/PGP, whereas 65.3% (n = 115) and 15.3% (n = 27), reported recurrent LBP/PGP or continuous LBP/PGP, respectively. The time between base line and the 12 months follow-up was in actuality 14 months. Women with previous LBP before pregnancy had an increased odds ratio (OR) of reporting 'recurrent pain' (OR = 2.47) or 'continuous pain' (OR = 3.35) postpartum compared to women who reported 'no pain' at the follow-up. Women with 'continuous pain' reported statistically significant higher level of pain at all measure points (0, 6 and 12 months postpartum). Non-responders were found to report a statistically significant less positive scoring regarding relationship satisfaction compared to responders. Conclusions: The results from this study demonstrate that persistent PLBP/PGP is a major individual and public health issue among women 14 months postpartum, negatively affecting their self-reported health. However, the perceived relationship satisfaction seems to be stable between the groups.

Prevalence and predictors of persistent pelvic girdle pain 12 years postpartum
- 2017

Ingår i: BMC Musculoskeletal Disorders. - : BIOMED CENTRAL LTD. - 1471-2474. ; 18

Tidskriftsartikel (refereegranskat)abstract
- Background: Pelvic girdle pain (PGP) is not always a self-limiting condition. Women with more pronounced persistent PGP (PPGP) report poorer health status compared to women with less pronounced symptoms. The knowledge concerning the long-term consequences of PPGP is limited, thus more knowledge in this area is needed. The overall aim was to study the prevalence and predictors of PPGP 12 years after delivery. Methods: This is a long-term follow-up study based on a previous cohort study that commenced in 2002. New questionnaire data 12 years postpartum were collected in 2014 and early 2015. The questionnaire was distributed to a total of 624 women from the initial cohort. Results: In total, 295 women (47.3%) responded to the questionnaire where 40.3% (n = 119) reported pain to a various degree and 59% (n = 174) reported no pain. Increased duration and/or persistency of pain, self-rated health, sciatica, neck and/or thoracic spinal pain, sick leave the past 12 months, treatment sought, and prescription and/or non-prescription drugs used were all associated with an statistically significant increase in the odds of reporting pain 12 years postpartum. Widespread pain was common and median expectation of improvement score was 5 on an 11-point numeric scale (interquartile range 2-7.50). More than one of five women (21.8%) reporting pain stated that they had been on sick leave the past 12 months and nearly 11% had been granted disability pension due to PPGP. No statistically significant differences were found between respondents and non-respondents regarding most background variables. Conclusions: This study is unique as it is one of few long-term follow-up studies following women with PPGP of more than 11 years. The results show that spontaneous recovery with no recurrences is an unlikely scenario for a subgroup of women with PPGP. Persistency and/or duration of pain symptoms as well as widespread pain appear to be the strongest predictors of poor long-term outcome. Moreover, widespread pain is commonly associated with PPGP and may thus contribute to long-term sick leave and disability pension. A screening tool needs to be developed for the identification of women at risk of developing PPGP to enable early intervention.

Tidskriftsartikel (refereegranskat)abstract
- Background: There is insufficient evidence regarding psychosocial factors and its long-term association with persistent pregnancy-related lumbopelvic pain. The overall aim of this study was to investigate women with persistent pregnancy-related lumbopelvic pain 12 years postpartum based on psychosocial and behavioural characteristics using the Swedish version of the Multidimensional Pain Inventory (MPI-S) classification system.Material and methods: This is a cross-sectional study based on a previous cohort. Data collection took place through a questionnaire. A total of 295 women from the initial cohort (n = 639) responded to the questionnaire giving a response rate of 47.3%. To determine the relative risk (RR) of reporting pain 12 years postpartum, a robust modified Poisson regression was used. This is the first study using the MPI-S as a predictive variable on women with persistent pregnancy-related lumbopelvic pain.Results: The MPI-S classification procedure was carried out on a total of n = 226 women, where 53 women were classified as interpersonally distressed (ID), 82 as dysfunctional (DYS), and 91 as adaptive copers (AC). Women in the ID and DYS subgroups had a relative risk (RR) of reporting persistent pregnancy-related lumbopelvic pain 12 years postpartum that was more than twice as high compared to the AC subgroup (95% confidence interval (CI) in parenthesis): RR 2.57 (CI 1.76 - 3.75), p<0.0001 and RR 2.23 (CI 1.53 - 3.25), p<0.0001 respectively. Women in the DYS subgroup had more than 5 times increased risk of reporting sick leave the past 12 months compared to the AC subgroup (RR 5.44; CI 1.70 - 17.38, p=0.004).Conclusions: The present study demonstrates that it is possible to classify women with persistent pregnancy-related lumbopelvic pain 12 years postpartum into relevant clinical subgroups based on psychosocial and behavioural characteristics using the MPI-S questionnaire.

Tidskriftsartikel (refereegranskat)abstract
- Background: Pregnancy related low back pain (PLBP) and pelvic girdle pain (PGP) are considered common complications of pregnancy. The long-term consequences for women with persistent PLBP/PGP postpartum are under-investigated. The main objective was to investigate the prevalence, pattern and degree of sick leave as well as healthcare utilisation and its perceived effect in women with persistent PLBP/PGP at 12 months postpartum.Method: This is a follow-up study of a cohort involving of a sample of women, who delivered from January 1st 2002 to April 30th in 2002 at Umea University Hospital and Sunderby Hospital, and who reported PLBP/PGP during pregnancy. A total of 639 women were followed-up by a second questionnaire (Q2) at approximately 6 months postpartum. Women with persistent PLBP/PGP at the second questionnaire (N = 200) were sent a third questionnaire (Q3) at approximately 12 months postpartum.Results: The final study sample consisted of 176 women reporting PLBP/PGP postpartum where N = 34 (19.3 %) reported 'no' pain, N = 115 (65.3 %) 'recurrent' pain, and N = 27 (15.3 %) 'continuous' pain. The vast majority (92.4 %) of women reported that they had neither been on sick leave nor sought any healthcare services (64.1 %) during the past 6 months at Q3. Women with 'continuous' pain at Q3 reported a higher extent of sick leave and healthcare seeking behaviour compared to women with 'recurrent' pain at Q3. Most women with persistent PLBP/PGP had been on sick leave on a full-time basis. The most commonly sought healthcare was physiotherapy, followed by consultation with a medical doctor, acupuncture and chiropractic.Conclusion: Most women did not report any sick leave or sought any healthcare due to PLBP/PGP the past 6 months at Q3. However, women with 'continuous' PLBP/PGP 14 months postpartum did report a higher prevalence and degree of sick leave and sought healthcare to a higher extent compared to women with 'recurrent' PLBP/PGP at Q3. Women with more pronounced symptoms might constitute a specific subgroup of patients with a less favourable long-term outcome, thus PLBP/PGP needs to be addressed early in pregnancy to reduce both individual suffering and the risk of transition into chronicity.

Effects of gonadal hormone deficiency on bone mineral density : can physical activity increase bone mineral density in women?
- 2006
-
Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Osteoporosis with its associated fragility fractures is a global health care problem. The incidence of ftagility ftactures has increased dramatically the last 50 years. This has been suggested to at least in part be due to the sedentary lifestyle in the modem society. The prevalence of osteoporosis increases with increasing age. In the decade following menopause, most women experience more rapid bone loss than that caused by aging alone. This is mainly due to the decreased ovarian estrogen secretion. Bone mineral density (BMD) decrease can be prevented by estrogen therapy. One of the aims of these studies was to investigate the effects of decreased levels of gonadal hormones on bone mineral density (BMD) in men and women. Men with prostate cancer were subjected to medical or surgical castration. This led to decreased testosterone levels and decreased bone mineral density. The decrease in bone mass was larger in the surgically castrated group. Treatment of fertile women with GnRH analogues for endometriosis for 6 months and hereby decreased estrogen levels led to a decrease in bone mineral density. Perimenopausal women with fluctuating estradiol levels and occasional ovulations were followed for 18 months. There was a significant decrease in BMD over an 18 months period. The main aim of this thesis was to study if moderate physical training could prevent the loss of bone mass or even increase BMD in women with low circulating estradiol levels. Therefore young women with endometriosis treated with GnRH analogues for 6 months were randomised to physical training for 12 months or no intervention. The subjects trained during six months of GnRH treatment and during six months following cessation of therapy. Perimenopausal women with fluctuating estradiol levels and postmenopausal women with a forearm fracture and low bone mineral density were randomized to training or to controls for 18 and 12 months respectively. The results indicate a moderately positive effect of physical training in all three studies. The groups were small and no direct comparison was made. The most pronounced positive effect of training on BMD was found in the young women during six months following cessation of GnRH therapy. The least pronounced effect was found in the postmenopausal women with low stable estradiol levels. We concluded that moderate physical activity can prevent perimenopausal decrease in BMD, increase BMD in postmenopausal women with low bone mass and increase the speed of recovery of bone mass after GnRH therapy in women of fertile age with endometriosis.

Preliminär skattning av utsläpp av växthusgaser 2013
- 2014
-
Rapport (övrigt vetenskapligt/konstnärligt)abstract
- Naturvårdsverket har uppdragit åt SMED att utföra preliminära skattningar av utsläpp av växthusgaser 2013 för publicering i slutet av april 2014. Med tanke på den korta tidsfristen och den i vissa fall begränsade tillgången till uppdaterade indata levereras skattningarna med en något annan sektorsindelning än till ordinarie rapportering. Utsläppen redovisas i Gg CO2-ekvivalenter totalt samt per sektor enligt den modifierade sektorsindelningen. Metodiken baseras i huvudsak på SMED 20121 och 1996 års rapporterings- och metodriktlinjer från UNFCCC och IPCC. Förutsättningarna och metodvalet skiljer sig åt mellan olika sektorer. För utsläpp från energiproduktion och transporter samt i viss mån industriprocesser och avfallsförbränning har data avseende 2013 funnits tillgängliga och utnyttjats. Utsläpp från jordbruk och avfallshantering exklusive förbränning har skattats genom framskrivning av tidigare års utsläpp med linjär regression. Resultatet av beräkningarna blev att Sveriges totala utsläpp av växthusgaser 2013 var 55 657 Gg CO2-ekvivalenter exklusive utrikes transporter. Det innebär en minskning med 3 procent jämfört med 2012 års utsläpp enligt submission 2014. Totalt 80 procent av utsläppen har beräknats baserat på uppdaterade data avseende 2013. Resultatet är preliminärt och 2013 års utsläpp kommer att revideras till ordinarie submission 2015. Inga osäkerhetsskattningar har gjorts. Den preliminära skattningen av 2012 års utsläpp som rapporterades i april 2013 enligt samma metodik var drygt en procent högre på aggregerad nivå än den slutgiltiga rapporteringen i submission 2014. Detta kan ge en grov fingervisning om den förväntade avvikelsen från den slutgiltiga skattningen. Den preliminära skattningen av 2013 års utsläpp som redovisas här kommer dock inte att vara direkt jämförbar med submission 2015 på grund av bytet av riktlinjer.

- The occurrence of methionine-enkephalin-Arg(6)-Phe(7) (MEAP) and dynorphin B (DYNB) representing two main precursors of opioids was analyzed in specimens from rat cortical bone, periosteum, bone marrow and joint tissue by radioimmunoassay (RIA). MEAP and DYNB were extracted in a solution of 4% EDTA in 2 M acetic acid previously proven suitable for extraction of sensory and autonomic neuropeptides in bone and joints. In crude extracts of cortical bone, the immunoreactive (ir) levels of both opioids were under the detection limit of RIA. As for DYNB this also applied to crude extracts of joints and periosteum. Therefore, two purification methods were tested and compared, i.e. reverse phase C 18 and ion exchange chromatography. RIA of the elution fraction disclosed a significant difference between the two methods in terms of recovery, i.e. <5% and 50%, respectively. Thus, purification by ion exchange chromatography prior to RIA appeared to be the most suitable by providing measurable levels of both MEAP and DYNB in all tissues analyzed (highest in bone marrow, lowest in cortical bone). The described method offers a means of quantifying opioid peptides in bone and joints, which may be utilized in the analysis of regulatory mechanisms of nociception, growth and immune responses in different conditions.

- Background Support from significant others is important for participation in everyday life for persons with rheumatoid arthritis (RA). Meanwhile, significant others also experience limitations. Aims To explore how support is expressed by persons with RA and significant others, and how support relates to participation in everyday life of persons with RA. Material and methods Sixteen persons with RA and their significant others participated in individual semi-structured interviews. The material was analyzed using dyadic analysis. Results Persons with RA and significant others reported that RA and support had become natural parts of everyday life, especially emotional support. The reciprocal dynamics of support were also expressed as imperative. Also, support from people outside of the dyads and well-functioning communication facilitated everyday life. Conclusions Significant others and the support they give are prominent factors and facilitators in everyday life of persons with RA. Concurrently, the support persons with RA provide is important, along with support from outside of the dyads. Significance The results indicate that the interaction between persons with RA and the social environment is central to gain insight into how support should be provided for optimal participation in everyday life. Significant others can preferably be more involved in the rehabilitation process.
