- 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
- Elbow osteoarthritis (OA) is a common cause of pain and lameness in dogs, often resulting from the developmental disorder elbow dysplasia. Currently, there is no effective treatment or cure for this disease. This study aimed to evaluate the effect of treating dogs with OA with stem cells (SVF, stromal vascular fraction) and blood plasma rich in platelets (PRP) derived from the dog's own fat and blood, respectively. The mixture was administered as a single injection into affected elbows. Nineteen dogs with elbow OA were treated with SVF and PRP. Subjective and objective evaluations were performed before treatment, after six months, and after a minimum of one year. A "Symmetry Squares" graphic presentation of objective gait forces (peak force and impulse) was also used to compare changes in gait over time. The results showed that subjective evaluation of clinical lameness was improved at the six-month follow up evaluation and that the peak force was transferred from the hind limbs to the front limbs in the treated dogs after 12 months. However, the treatment failed to show a general evident effect. Further research should be conducted to evaluate whether SVF and PRP treatment should be recommended for dogs with elbow OA. (1) Background: The aim of the current pilot study was to describe the long-term effects of a single intra-articular injection of autologous stromal vascular fraction (SVF) with platelet-rich plasma (PRP) in dogs with confirmed elbow OA, using orthopedic lameness scoring and kinetic and kinematic gait analysis. For comparison of normal long-term variation of gait over time, a group of healthy control dogs (CDs) was also evaluated. (2) Methods: A prospective longitudinal clinical pilot study investigating 19 client-owned dogs with elbow OA (OADs) treated with SVF and PRP and eight CDs not receiving treatment. The OAD and CD groups were evaluated before and after 6 and at least 12 months following treatment with SVF and PRP (OAD group) and twice with a six-month interval (CD group), respectively, through orthopedic examinations, goniometry, and kinetic and kinematic analyses (seven variables). (3) Results: The OAD had an increase in fore-hind peak force symmetry >= 12 months after treatment (p < 0.05), but no other objective variables changed over time. Orthopedic consensus scores had improved at >= six months follow-up evaluation (p < 0.05). None of the investigated gait variables had changed at >= six months follow-up evaluation in the CD group. (4) Conclusions: The current study could not confirm a significant benefit from SVF and PRP treatment in OADs, but future studies should be conducted in order to fully evaluate the potential of the treatment. The improvement seen in fore-hindlimb symmetry may represent an improvement in gait or an incidental finding.

Pregnancy-related low back pain and pelvic girdle pain approximately 14 months after pregnancy : pain status, self-rated health and family situation
- 2014
-
Ingår i: BMC Pregnancy and Childbirth. - : Springer Science and Business Media LLC. - 1471-2393 .- 1471-2393. ; 14

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.

Sick leave and healthcare utilisation in women reporting pregnancy related low back pain and/or pelvic girdle pain at 14 months postpartum
- 2016

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.

Tidskriftsartikel (refereegranskat)abstract
- 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.

Tidskriftsartikel (refereegranskat)abstract
- Background: Rheumatoid arthritis (RA) is a chronic inflammatory disease often associated with disability. Despite new treatments, pain and activity limitations are still present. Objectives: To describe how persons with RA experience and manage pain in their daily life. Methods: Seven semi-structured focus groups (FGs) were conducted and analyzed using content analysis. Results: The analysis revealed four categories: 1) Pain expresses itself in different ways referred to pain as overwhelming, aching or as a feeling of stiffness. 2) Mitigating pain referred to the use of heat, cold, medications and activities as distractions from the pain. 3) Adapting to pain referred to strategies employed as coping mechanisms for the pain, e.g. planning and adjustment of daily activities, and use of assistive devices. 4) Pain in a social context referred to the participants social environment as being both supportive and uncomprehending, the latter causing patients to hide their pain. Conclusions: Pain in RA is experienced in different ways. This emphasizes the multi-professional team to address this spectrum of experiences and to find pain management directed to the individual experience that also include the persons social environment.

- Purpose: To describe the meaning of significant others in relation to participation in everyday life of persons with early diagnosed rheumatoid arthritis (RA). Materials and methods: Fifty-nine persons participated in this interview study. Inclusion criteria were three years’ experience of diagnosis and being of working age. Semi-structured interviews were conducted using critical incident technique (CIT), and the material was analysed using content analysis. Results: Four categories were revealed: (1) My early RA causes activity adaptations for us all, referring to the person and significant others modifying activities. (2) Making the significant others balance between shortfalls and participation, where the participants distinguished between needing help and feeling involved in activities. (3) Physical interactions with significant others, referring to both the problematic and manageable impact RA could have on body contact. (4) Emotions in relation to activities with others, where participants described feelings of failing others, and anxiety about future activities. Conclusions: For persons with early diagnosed RA, significant others can be both hindering and facilitating for participation in everyday life. As a clinical implication, it is valuable to identify how significant others can be involved in the rehabilitation process, to enhance participation in everyday life early in the disease process.Implications for rehabilitation Significant others of persons with rheumatoid arthritis can facilitate as well as hinder participation in everyday life, even early in the disease process. It is important to include the significant others in the rehabilitation process of persons with early diagnosed rheumatoid arthritis. It is of great importance to identify when and how significant others can be facilitators of participation in everyday life for persons with early rheumatoid arthritis. To make it easier for significant others to facilitate participation, there is a need for the healthcare system to explore ways to support significant others with easily accessible information about early rheumatoid arthritis.

The role of support from significant others in the association between disease-related factors and sickness absence in early rheumatoid arthritis : a longitudinal study
- 2021

Tidskriftsartikel (refereegranskat)abstract
- Objective: The aim of this study was to analyse how support from significant others affects the associations between disease-related variables and sickness absence during the first 2 years after rheumatoid arthritis (RA) diagnosis. Method: Data from 274 people with RA (73% women) of working age (18-63 years) were retrieved from the Swedish early RA cohort TIRA-2. These data concerned disease-related variables (disease activity, activity limitations, pain intensity, and grip force), sickness absence, and perceived support from significant others. Associations of disease-related variables with sickness absence and how these associations were moderated by support from significant others were analysed using zero-inflated negative binomial regression. Results: During the 2 years after diagnosis, higher disease activity was significantly associated with increased odds of sickness absence, a connection strengthened by perceived support from family during the first year. More perceived support was also directly and significantly associated with increased odds of sickness absence during the first year. Conclusions: Support from significant others is related to sickness absence in RA, specifically during the first year after diagnosis. Although patients report high levels of support from significant others, this does not necessarily lead to more positive work outcomes. Therefore, it is important to consider other aspects of support that might influence work outcomes, e.g. type and quality of support. Future research should investigate these forms of support, and when significant others should be encouraged to support in the rehabilitation process to increase the chances of people with RA having a well-functioning and sustainable work life.

Sustainability Assessment of Food Redistribution Initiatives in Sweden
- 2020

Ingår i: Resources. - : MDPI AG. - 2079-9276. ; 9
-
Tidskriftsartikel (refereegranskat)abstract
- Food banks that redistribute surplus food from retailers and the food industry to people in need are not a new concept globally, but their connection to food waste prevention is new. As a result, new types of food redistribution units are emerging and diversifying to find new target groups and distribution methods. The aim of this study was to identify and study surplus food redistribution units in Sweden,and then to assess the impact on several sustainability indicators for selected redistribution units, in order to increase knowledge on the types of values these redistribution concepts generate. The methods used for analyzing the scenarios were Environmental Life Cycle Assessment, Life Cycle Costing and Social Life Cycle Assessment. The results showed that providing food bags to socially exposed people generated the largest reduction of greenhouse gas emissions per kg of redistributed food (−1.2 kg CO2eq./FU). Reprocessing surplus food to a high-quality end-product was attributed a high social value, due to job creation effects in the high number of working hours required per kg of redistributed food. With regard to economic impacts, all but two scenarios studied had monthly financial losses,and therefore needed other sources of financial support.

- Patients with rheumatoid arthritis (RA), particularly those with severe disease, have increased risk of cardiovascular disease (CVD). Previous studies suggest that endothelial cell activation may contribute to this co-morbidity, and that treatment with tumour necrosis factor (TNF) inhibitors could reduce the risk of CVD in these patients. The aim of this study was to investigate endothelial cell activation markers in muscle tissue of patients after adalimumab treatment.

- AimsIdiopathic scoliosis is the most common spinal deformity in adolescents and children. The aetiology of the disease remains unknown. Previous studies have shown a lower bone mineral density in individuals with idiopathic scoliosis, which may contribute to the causation. The aim of the present study was to compare bone health in adolescents with idiopathic scoliosis with controls.MethodsWe included 78 adolescents with idiopathic scoliosis (57 female patients) at a mean age of 13.7 years (8.5 to 19.6) and 52 age- and sex-matched healthy controls (39 female patients) at a mean age of 13.8 years (9.1 to 17.6). Mean skeletal age, estimated according to the Tanner-Whitehouse 3 system (TW3), was 13.4 years (7.4 to 17.8) for those with idiopathic scoliosis, and 13.1 years (7.4 to 16.5) for the controls. Mean Cobb angle for those with idiopathic scoliosis was 29° (SD 11°). All individuals were scanned with dual energy x-ray absorptiometry (DXA) and peripheral quantitative CT (pQCT) of the left radius and tibia to assess bone density. Statistical analyses were performed with independent-samples t-test, the Mann-Whitney U test, and the chi-squared test.ResultsCompared with controls, adolescents with idiopathic scoliosis had mean lower DXA values in the left femoral neck (0.94 g/cm2 (SD 0.14) vs 1.00 g/cm2 (SD 0.15)), left total hip (0.94 g/cm2 (SD 0.14) vs 1.01 g/cm2 (SD 0.17)), L1 to L4 (0.99 g/cm2 (SD 0.15) vs 1.06 g/cm2 (SD 0.17)) and distal radius (0.35 g/cm2 (SD 0.07) vs 0.39 g/cm2 (SD 0.08; all p ≤ 0.024), but not in the mid-radius (0.72 g/cm2 vs 0.74 g/cm2; p = 0.198, independent t-test) and total body less head (1,559 g (SD 380) vs 1,649 g (SD 492; p = 0.0.247, independent t-test). Compared with controls, adolescents with idiopathic scoliosis had lower trabecular volume bone mineral density (BMD) on pQCT in the distal radius (184.7 mg/cm3 (SD 40.0) vs 201.7 mg/cm3 (SD 46.8); p = 0.029), but not in other parts of the radius or the tibia (p ≥ 0.062, Mann-Whitney U test).ConclusionIn the present study, idiopathic scoliosis patients seemed to have lower BMD at central skeletal sites and less evident differences at peripheral skeletal sites when compared with controls.

- BACKGROUND: Increased transforming growth factor-beta (TGF-beta) levels are associated with fibrosis, affected cell proliferation, and postsurgical adhesion development, but the knowledge regarding TGF-beta response to the surgical trauma is limited. This study investigated TGF-beta(1-3) isoforms and fibrinolytical factors in peritoneal serosal fluid during abdominal surgery, together with the in vitro effect of TGF-beta(1-3) on human mesothelial cell proliferation. MATERIALS AND METHODS: Total as well as biologically active TGF-beta(1-3) and fibrinolytic factors: t-PA, uPA, and PAI-1 were measured in serosal fluid and plasma from 23 patients undergoing colorectal cancer surgery. In vitro proliferation of human primary mesothelial cell cultures upon TGF-beta(1-3) stimulation was also investigated. RESULTS: Total TGF-beta1 and TGF-beta2 levels were similar in serosal fluid and plasma while active fractions were increased in serosal fluid. In contrast, total fraction of TGF-beta3 was higher in serosal fluid compared with plasma, while levels of active fractions did not differ. Plasminogen activators (t-PA, uPA) were elevated while the inhibitor (PAI-1) was decreased in serosal fluid compared with plasma. The in vitro mesothelial cell proliferation studies revealed that high TGF-beta(1-3) concentrations decreased cell proliferation, while lower concentrations of TGF-beta1 increased mesothelial cell proliferation. CONCLUSIONS: This human study shows increased active TGF-beta levels in peritoneal serosal fluid, compared with plasma, during abdominal surgery and that TGF-beta1 at physiological concentrations increased human mesothelial cell proliferation in vitro. TGF-beta cytokines may be involved in postsurgical adhesion formation.

- Six children, between 3 and 5 years of age, having infantile autism according to DSM-III-R, were treated for 3 months with 6R-L-erythro-5,6,7,8-tetrahydrobiopterin (R-BH4), a cofactor for tyrosine hydroxylases in the biosynthetic pathway of catecholamines and serotonin. A criterion for inclusion in the study was a relatively low level of R-BH4 in the cerebrospinal fluid. For clinical evaluation, the Parental Satisfaction Survey (PASS) was used every fourth week and the Griffiths Developmental Scales were used before starting and 3 months after completing the treatment. During the treatment period, all parents reported improvements in the child's social functioning-mainly eye contact and desire to interact-and in the number of words or sounds which the child used. Small positive changes were noted on the Griffiths Developmental Scales between the two testing occasions. R-BH4 levels in CSF increased significantly after treatment. The positron emission tomography (PET) study showed that the high value of dopamine D2 receptor binding in the caudate and putamen decreased by about 10% towards the normal level after treatment with R-BH4. The observations in this open study indicate that the drug might be useful for a subgroup of children with autism, but there is a need for a larger double-blind study with a longer treatment period.

- IL-6 is produced and released in large amounts from skeletal muscle during prolonged exercise in both mice and humans, but there are few data indicating the biological significance of this. IL-6 exerts metabolic effects such as stimulating energy expenditure and reducing body fat mass. We have now investigated the effects of IL-6 deficiency on exercise endurance and energy expenditure in preobese and obese IL-6-deficient (IL-6(-/-)) mice. Four-month-old preobese and 7-month-old obese IL-6(-/-) male mice backcrossed to C57BL/6 and their littermate controls were exercised on a treadmill, and energy expenditure was measured as oxygen consumption with the use of indirect calorimetry. The preobese IL-6(-/-) mice were significantly leaner than the control mice, whereas the older IL-6(-/-) mice, as expected, had developed obesity. Resting young, but not older, IL-6(-/-) mice had an elevated respiratory exchange ratio (RER), indicating that they oxidize carbohydrates rather than fat for energy utilization. During exercise, the young and older IL-6(-/-) mice had a reduced endurance and a progressive decrease in oxygen consumption compared with control mice. There was no difference in RER in young IL-6(-/-) mice, whereas RER was enhanced in older IL-6(-/-), mice during exercise. In summary, IL-6(-/-) mice have reduced endurance and energy expenditure during exercise, suggesting that IL-6 is necessary for normal exercise capacity.

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Background: Vitamin D is a prohormone that plays a key role in the calcium and phosphate balance and has physiological functions throughout the entire body. Vitamin D is supplied by exposure to ultraviolet light or by food. The prevalence of vitamin D deficiency in immigrants in Northern Sweden was unknown. There was no consensus on how to define or treat vitamin D deficiency and no pure preparations of cholecalciferol available in Sweden.Aims: To study the prevalence and determinants of vitamin D deficiency in immigrants of African and Middle Eastern origin, to examine associations between vitamin D status and muscle strength, anxiety, depression and quality of life, and to determine the effect of supplementation with cholecalciferol on 25-hydroxyvitamin D3 [25(OH)D] and vitamin D status.Methods: 1. A cross-sectional, population-based study. Immigrants ages 25-65 from Africa and the Middle East (n=1306) living in Umeå, Sweden, were invited to participate. A total of 111 men and 106 women (16.5%) participated. 25(OH)D was measured by LC-MsMs. Anthropometry, medical, socioeconomic and lifestyle data was registered. Examinations: lower limb muscle strength, grip strength, HAD, health-related quality of life (QoL) 2. An open, partially randomized, controlled trial including immigrants from Africa or the Middle East, 192 subjects screened, 160 included and 147 completed the study. Intervention: cholecalciferol 12±2 weeks, 4 parallel groups; Group 1: 25(OH)D <25nmol/L: 10000 IU/d, Groups 2a and 2b: 25(OH)D 25-49 nmol/L: 2000 IU/d or 2000 IU/w, Group 3: 25(OH)D 50-74 nmol/L: 2000 IU/d.Results: Twelve percent of the immigrants showed a vitamin D deficiency (25(OH)D ˂25 nmol/L) and 73 % showed 25(OH)D ˂50 nmol/L. Vitamin D deficiency was twice as common in African immigrants as in the Middle Eastern group. Vitamin D deficiency was associated with intake of fatty fish less than once a week, absence of travel abroad and use of long-sleeved clothing in summer. Lower limb muscle strength was associated with 25(OH)D levels and weaker grip strength was associated with vitamin D deficiency. Vitamin D deficiency was not associated with anxiety, depression or QoL in the total immigrant population. In Middle Eastern women, in whom prevalence of anxiety was higher, anxiety was associated with 25(OH)D ≤49 nmol/L. Oral cholecalciferol was effective in increasing 25(OH)D. At study end, 100% in Group 1, 89% in Group 2a, 55% in Group 2b and 96% in Group 3 reached adequate vitamin D status (25(OH)D ˃50 nmol/L). In Group 1; 62 % reached 25(OH)D ≥125 nmol/L.Conclusions: Vitamin D deficiency and insufficiency was common in the immigrant group and no difference was shown between men and women. A diet including a high intake of fatty fish was most important in avoiding vitamin D deficiency. Vitamin D status was associated with muscle strength in all immigrants. Vitamin D deficiency was not associated with anxiety, depression or QoL in the immigrants. In female immigrants from the Middle East, anxiety was associated with 25(OH)D levels ≤49 nmol/L. Supplementation with cholecalciferol 2000 IU/day for three months was safe in healthy individuals with initial 25(OH)D 25-49 nmol/L, but monitoring is warranted since 11 % did not attain sufficient vitamin D status. The dose 10 000 IU/day in patients with initial 25(OH)D <25 nmol/L was unnecessarily high.
