- Background: Patients with type 1 diabetes have a high prevalence of upper extremity impairments (UEIs), such as frozen shoulder, carpal tunnel syndrome, and trigger finger. The UEIs are strongly associated with activity limitations and impaired quality of life. The etiology of the UEI is not clear. Vitamin D deficiency has been considered to play a role in the pathogenesis of type 1 diabetes and in the development of macro- and microvascular complications in diabetes. Aim: To characterize vitamin D status in a large population of patients with type 1 diabetes, if vitamin D deficiency is associated with metabolic factors and possible association with UEI. Material and methods: Patients who diagnosed before 35 years of age, whose diabetes duration >20 years, and who are not older than 65 years were invited to participate in this cross-sectional case-control, multicenter study. Controls matched for age and sex were obtained from the national population registry. Fasting blood samples were collected and stored at -80 degrees C until analyzed regarding 25-hydroxy-vitamin D (25(OH)D3) by a liquid chromatographic-mass spectrometric method (LC-MS/MS). Results: Vitamin D levels varied with season as expected in the northern hemisphere. The association between 25(OH)D3 and clinical variables was analyzed in a univariate general linear model, which indicated no difference in 25(OH)D3 in men with and without diabetes but higher values in women with diabetes. About 30% of both patients and controls had vitamin D deficiency (=50 nmol/L). Analyzed by binary logistic regression UEIs was not associated with 25(OH)D3 levels. In both patients and controls, 25(OH)D3 was correlated to apolipoprotein A1 (r = 0.153; 0.220, P < 0.001). Conclusion: In patients with type 1 diabetes and a duration of 20 years or more, vitamin D level is not lower than in nondiabetic controls and is not associated with UEIs.

- The SummaryThis study examined the imminent risk of a future fracture within 1 and 2years following a first fracture in women aged 50years and older and assessed independent factors associated with risk of subsequent fractures. The study highlights the need to intervene rapidly after a fracture to prevent further fractures.IntroductionThis study aims to determine the imminent risk of subsequent fractures within 1 and 2years following a first fracture and to assess independent factors associated with subsequent fractures.MethodsRetrospective, observational cohort study of women aged 50years with a fragility fracture was identified from Swedish national registers. Clinical/demographic characteristics at the time of index fracture and cumulative fracture incidences up to 12 and 24months following index fracture were calculated. Risk factors for subsequent fracture were identified using multivariate regression analysis.ResultsTwo hundred forty-two thousand one hundred eight women (mean [SD] age 74 [12.5] years) were included. The cumulative subsequent fracture incidence at 12months was 7.1% (95% confidence interval [CI], 6.9-7.2) and at 24months was 12.0% (95% CI, 11.8-12.1). The rate of subsequent fractures was highest in the first month (similar to 15 fractures per 1000 patient-years) and remained steady between 4 and 24months (similar to 5 fractures/1000 patient-years). Higher age was an independent risk factor for imminent subsequent fractures (at 24months, sub-distribution hazard ratio [HR], 3.07; p<0.001 for women 80-89years [reference 50-59years]). Index vertebral fracture was a strong independent risk factor for subsequent fracture (sub-distribution HR, 2.72 versus hip fracture; p<0.001 over 12months; HR, 2.23; p<0.001 over 24months).ConclusionsOur findings highlight the need to intervene rapidly after any fragility fracture in postmenopausal women. The occurrence of a fragility fracture provides healthcare systems with a unique opportunity to intervene to reduce the increased risk of subsequent fractures.

- Bone mineral density (BMD) is an established measure used to diagnose patients with osteoporosis. In clinical trials, change in BMD has been shown to provide a reliable estimate of fracture risk reduction, and achieved BMD T-score has been shown to reflect the near-term risk of fracture. We aimed to test the association between BMD T-score and fracture risk in patients treated for osteoporosis in a real-world setting. This retrospective, observational cohort study included Swedish females aged ≥55 years who had a total hip BMD measurement at one of three participating clinics. Patients were separated into two cohorts: bisphosphonate-treated and bisphosphonate-naïve prior to BMD measurement, stratified by age and prior nonvertebral fracture status. The primary outcome was cumulative incidence of clinical fractures within 24 months of BMD measurement, with other fracture types included as secondary outcomes. Associations between T-score and fracture risk were estimated using proportional hazards regression and restricted cubic splines. A total of 15,395 patients were analyzed: 11,973 bisphosphonate-naïve and 3422 bisphosphonate-treated. In the 24 months following BMD measurement, 6.3% (95% confidence interval [CI], 5.9–6.7) of bisphosphonate-naïve and 8.4% (95% CI, 7.5–9.4) of bisphosphonate-treated patients experienced a clinical fracture. Strong inverse relationships between BMD T-score and fracture incidence were observed in both cohorts. Among bisphosphonate-naïve patients, this relationship appeared to plateau around T-score −1.5, indicating smaller marginal reductions in fracture risk above this value; bisphosphonate-treated patients showed a more consistent marginal change in fracture risk across the evaluated T-scores (−3.0 to –0.5). Trends remained robust regardless of age and prior fracture status. This real-world demonstration of a BMD–fracture risk association in both bisphosphonate-naïve and bisphosphonate-treated patients extends evidence from clinical trials and recent meta-regressions supporting the suitability of total hip BMD as a meaningful outcome for the clinical management of patients with osteoporosis.

Aspects of Vitamin D : Prevalence of deficiency and impact on musculoskeletal parameters
- 2017

Doktorsavhandling (övrigt vetenskapligt/konstnärligt)abstract
- Vitamin D is central in calcium turnover, and adequate levels are important for skeletal health. It is not clear how large contributions from food and sunlight are in Swedish primary care patients, considering the low radiation of UVB in Sweden and fortification of some foods, and whether differences exist between patients of immigrant and Swedish origin. Increasing incidence of osteoporosis-related fractures is a major global health problem. Genetic variations in metabolising enzymes and in the Vitamin D receptor (VDR) have also been shown to be of importance to the overall effect of vitamin D. Polymorphic variation in the gene CYP2R1 encoding the 25-hydroxylase has previously been reported to correlate with circulating levels of 25(OH)D3. Results of association studies between genetic variants of the VDR and muscle strength, as well as falls have been contradictory.The purposes of this thesis were to examine possible differences in plasma-25(OH)D3 levels and intake of vitamin D between Swedish and immigrant female primary care patients, to estimate what foods contribute the most, and to identify contributors to vitamin D status (Paper I-II). Furthermore, the relationship between polymorphisms in the CYP2R1 gene and levels of 25(OH)D3 as well as other biochemical parameters (parathyroid hormone, calcium, phosphate and fibroblast growth factor 23) of skeletal homeostasis, bone mineral density and incidence of fractures was investigated (Paper III). Also, the association between genetic variations in the gene for the vitamin D receptor and measures of muscle strength, physical performance and falls (Paper IV), was investigated by using data from a Swedish multicenter study of elderly men (MrOS).Most important results: Vitamin D deficiency was common, with significant difference between Swedish born and immigrant patients (Paper I). Food intake of vitamin D is associated with circulating vitamin D, but the factors most strongly affecting vitamin D levels were reported sun holiday and origin (Paper II). CYP2R1 polymorphisms are associated with circulating levels of 25(OH)D3 and bone mineral density (Paper III). VDR genetic variants do not appear to have a direct effect on muscle strength or physical performance and incidence of falls in elderly Swedish men (Paper IV).

- Background: Digital resources in learning are increasingly available and offer new possibilities in education. Mobile learning devices (MLD) such as tablets provide easy and flexible access for users.Purpose: To investigate whether the introduction of MLDs in radiology education affected time spent on studies over a longer time frame and whether learning behavior and attitudes changed.Material and Methods: The radiology residents employed during 2015–2016 were invited to participate in this 12-month MLD intervention study. Results were evaluated using online questionnaires at six months (6 m) and 12 months (12 m).Results: Thirty-one residents were included, of whom half were in the early stages of residency (<2 years). After the MLD introduction, most participants (91% [6 m] and 83% [12 m]) estimated increased time spent on studies. Of these, 32% stated “a lot more” at 6 m but only 8% at 12 m (P ¼ 0.12). The MLDs showed positive effects on the experience of radiology studies, as a majority of participants stated better quality and effectiveness in their studies (100% [6 m]–92% [12 m]), that MLD facilitated access to educational materials to a high degree (83% [6 m]–75% [12 m]), and that studies had become better and more fun (96% [6 m]–100% [12 m]).Conclusion: The use of MLDs seems to facilitate learning effectively for radiologic residents. However, a larger scale study is required as a trend of decreasing figures in the longer term was seen, but our results did not show a significant reduction of time spent on radiology studies.

- IntroductionPatient education in combination with physical activity has been proposed as a way of increasing health-related quality of life and functional capacity in patients with osteoporosis. A randomised pilot study called the School of Osteoporosis in Linkoping (SOL) was conducted in 2018 for persons aged >= 60 years with established spinal osteoporosis. The SOL was scheduled for ten weeks with once-weekly theory education with or without additional supervised physical group training. The purpose of the present study was to explore the experiences of having participated in an osteoporosis school in persons with established spinal osteoporosis.Materials and methodsTen participants who had completed the SOL with patient education and supervised physical group training were invited to individual interviews, while six persons were accepted to participate. Qualitative content analysis was conducted with an inductive approach.FindingsThree main categories were identified from the interviews: The structure of the osteoporosis school; Gained knowledge related to the education in the osteoporosis school; and Experiences of health status one-year post-intervention. Seven associated subcategories were identified. Increased knowledge and perceptions of improved health acquired by the interventions were emphasised. However, continued supervised group training was requested and there were also concerns about worsened health at the one-year post-intervention follow-up.ConclusionThe tailored content and the group aspects of the structured osteoporosis school were experienced as the most important factors for successful results.

- Background:People with osteoporotic vertebral compression fractures (VCFs) have decreased health-related quality of life (HRQoL). Yoga and mindfulness are methods that can promote well-being. Objective:The aim of this article was to explore the effect of mindfulness and modified medical yoga on HRQoL, stress, sleep, and pain in people 60 years or older with a diagnosed osteoporotic VCF. Design:The School of Osteoporosis in Linkoping (SOL) is a pilot study with randomized groups. Materials and Methods:The SOL-study was scheduled to once a week for 10 weeks. Ten people were randomized to a theory (T) group, and ten people were randomized to a theory and mindfulness/medical yoga (MMY) group. The educational sessions lasted 60 min and were similar for the groups, but they took place at different facilities. An experienced physiotherapist supervised the MMY sessions for 60 min. Sleep quality and present stress experience were measured on a symmetric Likert scale. The numeric rating scale was used for pain, and EQ-5D, RAND-36, and Qualeffo-41 were used for HRQoL. The patient enablement instrument (PEI) was used to reflect how the participants coped with their illness. Results:Eight women in the MMY-group and seven women in the T-group completed the SOL study interventions. The adherence to the intervention program was 89% in the MMY-group and 87% in the T-group. There was no adverse consequence of the MMY training. After the 10-week intervention period, sleep quality (p = 0.018) and present stress (p = 0.043), but not perceived pain were improved in the MMY-group. The social function (SF) domain was improved in the MMY-group that was measured by both RAND-36 (p = 0.028) and Qualeffo-41 (p = 0.012). There was a trend toward a better PEI-score in the MMY-group compared with the T-group postintervention (p = 0.089). Conclusion:This article suggests that mindfulness and modified medical yoga supervised by a skilled physiotherapist may be a feasible way to improve SF, sleep, and stress in older women with osteoporotic VCFs.

- Aim. The aims of the current study were (1) to determine the prevalence of upper extremity impairments (UEIs) in patients with type 1 diabetes by clinical investigation; (2) to investigate if self-reported impairments were concordant with clinical findings and if key questions could be identified; and (3) to investigate if answers to our self-reported questionnaire regarding UEIs are reliable. Methods. Patients with type 1 diabetes were invited to participate in a cross-sectional study of clinical and self-reported (12 items) UEIs in adjunction to ordinary scheduled clinical visit. Before the visit, a questionnaire on UEIs was filled in twice (test-retest) followed by clinical testing at the planned visit. Results. In total, 69 patients aged and with diabetes duration were included in the study. In the clinical examination, two-thirds (65%) of the patients showed one or more UEI, with failure to perform hand against back as the most common clinical finding (40%) followed by positive Phalen’s test (27%), Tinel’s test (26%), and Prayer’s sign (24%). UEIs observed by clinical examination were often bilateral, and multiple impairments often coexisted. Self-reported shoulder stiffness was associated with impaired shoulder mobility and with Prayer’s sign. Self-reported reduced hand strength was associated to lower grip force, Prayer’s sign, trigger finger, fibrosis string structures, and reduced thenar strength as well as reduced shoulder mobility. In addition, self-reporting previous surgery of carpal tunnel and trigger finger was associated with several clinical UEIs including shoulder, hand, and finger. The test-retest of the questionnaire showed a high agreement of 80-98% for reported shoulder, hand, and finger impairments. Conclusion. UEIs are common in type 1 diabetes. Self-reported shoulder stiffness and reduced hand strength might be used to capture patients with UEIs in need of clinical investigation and enhanced preventive and therapeutic strategies, as well as rehabilitative interventions.

- ContextIn type 1 diabetes (T1D), dysregulation of the GH-IGF-1 axis has been reported. Whether this is related to upper extremity impairments (UEI) is unknown. ObjectiveExamine differences in GH-IGF-1 axis between T1D on subcutaneous insulin treatment and matched controls without diabetes and possible associations between GH-IGF-1 axis and UEI. DesignCross-sectional population-based study. Patients with T1D, onset amp;lt;35years, duration 20years, amp;lt;67years old and controls were invited to answer questionnaires and take blood samples. SubjectsA total of 605 patients with T1D and 533 controls accepted to participate. OutcomesFasting levels of IGF-1, IGF-1 Z-score, IGFBP-1, IGFBP-3, C-peptide, GH and UEI. ResultsPatients with T1D had lower IGF-1 and IGFBP-3 and higher IGFBP-1 and GH than controls. The difference in IGF-1 persisted with age. Insulin dose was associated with increasing IGF-1 Z-score but even at a very high insulin dose (amp;gt;1U/kg) IGF-1 Z-score was subnormal compared to controls. IGF-1 Z-score was unaffected by glycaemic control (HbA1c) but increased with residual insulin secretion, (C-peptide 1-99 pmol/L). IGFBP-1 was associated with fasting blood glucose, negatively in controls and positively in patients with T1D probably reflecting insulin resistance and insulin deficiency, respectively. There was no association between lower IGF-1 Z-score and UEI in T1D. ConclusionIn adult T1D with fair glycaemic control, the GH-IGF-1 axis is dysregulated exhibiting GH resistance, low IGF-1 and elevated IGFBP-1. Subcutaneous insulin cannot normalize these changes while endogenous insulin secretion has marked effects on IGF-1 pointing to a role of portal insulin.

- Purpose: To compare health-related quality of life (HRQOL) in type 1 diabetes and non-diabetic controls and possible links to upper extremity impairments (UEIs). Prevalence of sick-leave and causes were investigated.Materials and methods: This Swedish population-based case-control study included type 1 diabetes patients <67 years old and with a diabetes duration ≥20 years. Participants completed a postal questionnaire including Short Form 36, and questions regarding UEIs, and sick-leave.Results: In total, 773 patients, aged 50 ± 10 years (diabetes duration 35 ± 10 years), and 708 non-diabetic controls, aged 54 ± 9 years, completed the study. Patients reported significantly lower HRQOL compared with controls. The difference was greatest for general health, vitality, and bodily pain. Patients with shoulder or hand but not finger impairments scored significantly lower than asymptomatic patients. The prevalence of sick leave was higher in patients vs. controls (23% vs. 9%, p < 0.001), and nearly half cited impairments from back, muscles, or joints as the main reason.Conclusions: Health-related quality of life is lower in type 1 diabetes than controls and in patients with shoulder and hand impairments than in asymptomatic. Musculoskeletal impairments (back/muscle/joints) have impact on work ability. Identification of UEIs is important for initiating preventative-, therapeutic-, and rehabilitative interventions.Implications for rehabilitationUpper extremity impairments (UEIs) that are common in type 1 diabetes, and associated with reduced health-related quality of life, should preferably be screened for on a regular basis along with other known diabetes complications.Early identification of UEIs is important to improve health by initiating preventive as well as therapeutic multi-professional rehabilitative interventions.Sick leave is higher in type 1 diabetes than in controls. Musculoskeletal impairments, including the back, muscles, and joints, are a common cause for sick leave warranting further studies.
