Abstract
INTRODUCTION Carpal tunnel syndrome is a common disorder affecting a substantial portion of the general population. Surgical intervention is often deemed necessary, with the median nerve release being one of the most frequent operations. Optimising all the aspects of this procedure can enhance patient satisfaction with the treatment. METHODS AND ANALYSIS We aim to determine the differences in the aesthetic outcome of the scar as well as the pain experienced during the healing process between the use of absorbable and non-absorbable sutures. The primary outcome measure will be the patients' subjective satisfaction with the aesthetic appearance of the scar 1 year after the operation. Secondary outcomes will include a similar evaluation of the aesthetics performed by a blinded outcome assessor, as well as pain experienced by the patients during the 2 weeks postoperatively. The severity and improvement of the patients' symptoms will also be measured by a Finnish version of the Boston Carpal Tunnel Questionnaire. Costs will be evaluated for both groups. Safety of the wound closure will be followed and reported. ETHICS AND DISSEMINATION This protocol was approved by the Research Ethics Committee of the Northern Savo Hospital District (2319/2021). The trial will be conducted in accordance with the principles of Good Clinical Practice and the Declaration of Helsinki. The results will be disseminated through publication in peer-reviewed journals. TRIAL REGISTRATION NUMBER NCT05503719.

Body composition, balance, functional capacity and falls in older women. Aging Clin Exp Res 2024; 36:76. [PMID: 38512411 PMCID: PMC10957703 DOI: 10.1007/s40520-024-02719-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/08/2023] [Accepted: 02/01/2024] [Indexed: 03/23/2024]
Abstract
BACKGROUND The aim of this study was to examine the association of body composition, muscle strength, balance, and functional capacity on falls and fall injuries among community-dwelling older women. METHODS The study comprised of a 2-year randomized controlled trial involving 914 women with an average age of 76.5 (SD = 3.3) years at baseline. The women were assigned to exercise intervention (n = 457) and control groups (n = 457). Clinical measurements were conducted at baseline, 12 months and 24 months. RESULTS During the 2-year follow up, total of 546 women (59.7%) sustained a fall. The total number of falls was 1380 and out of these, 550 (40%) of falls were non-injurious and 745 (54%) were injurious. Higher femoral neck bone mineral density (BMD) was associated with a higher overall risk of falls [RR = 2.55 (95% CI = 1.70-3.84, p < 0.001)], but was a protective factor for severe fall injuries [RR = 0.03 (95% CI = 0.003-0.035, p < 0.01)]. Slower Timed Up and Go (TUG) was associated with an increased overall risk of falls [RR = 1.07 (95% CI = 1.05-1.10, p < 0.001)] and injuries requiring medical attention [RR = 1.10 (95% CI = 1.02-1.19, p = 0.02)]. Longer single leg standing time was a protective factor for falls [RR = 0.99 (95% CI = 0.99-1.00, p < 0.01)] and overall injurious falls [RR = 0.99 (95% CI = 0.99-1.00, p = 0.02)]. CONCLUSION For postmenopausal women with higher femoral neck BMD appear to sustain more falls, but have a lower risk of severe fall injuries. Better TUG and single leg standing time predict lower risk of falls and fall injuries.

Abstract
Objectives To determine the diagnostic cut-off values of components for sarcopenia in Caucasian women. Methods The present retrospective cross-sectional study based on the REFERENCE sample included 400 healthy women aged 20 to 40 years, and the OSTPRE sample included 344 women aged 63 to 75. The subjects of the OSTPRE population were re-measured five and ten years later after the baseline. Both samples underwent grip strength (GS), quadriceps strength (QS), and total-body DXA (TB-DXA) measurements, from which Relative Skeletal Muscle Mass Index (RSMI) was calculated. Results In the REFERENCE population, the -1 SD / -2 SD cut-off points were for RSMI 5.8 kg/m2 / 5.1 kg/m2, for GS 32.0 kg / 26.4 kg, and for QS 39.8 kg / 29.8 kg. The prevalence of under -2 SD distributions in REFERENCE were: RSMI 1.8%, GS 1.3%, and QS 2.0%, and in OSTPRE (15/20/25 years measurements): RSMI 1.2 %/1.9 %/0.5 %, GS 52.2%/42.3%/48.8%, and QS 47.4%/55.2%/not available. The distributions of GS and QS were statistically significantly different between REFERENCE and all OSTPRE measurement points (p<0.001 in Chi-squared). Conclusions The diagnostic cut-offs for components of sarcopenia are RSMI 5.1 kg/m2, grip strength 26.4 kg, and quadriceps strength 29.8 kg in Finnish Caucasian women.

Protocol for a double-blinded randomised controlled trial investigating the use of adjunct bicarbonate in carpal tunnel release: a single-centre study. BMJ Open 2023; 13:e071488. [PMID: 37723109 PMCID: PMC10510898 DOI: 10.1136/bmjopen-2022-071488] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 08/24/2023] [Indexed: 09/20/2023] Open
Abstract
INTRODUCTION This study aims to compare the effectiveness of buffered and non-buffered long-acting local anaesthetics in pain relief during and after carpal tunnel release (CTR) surgery. Carpal tunnel syndrome (CTS) is the most common peripheral nerve entrapment syndrome. Surgical treatment of CTS, CTR, is the most common hand surgical operation. CTR is usually performed under local anaesthesia, the application of which is often the most painful event during the procedure. One important aspect of patient satisfaction is adequate pain management during and after CTR. Long-acting local anaesthetics provide good postoperative pain control. Adjunct bicarbonate has been shown to reduce pain during injection of local anaesthetic and to prolong its analgesic effect. To date, no published randomised controlled trial has compared buffered to non-buffered long-acting local anaesthetic during CTR. METHODS AND ANALYSIS The study will randomly assign 116 patients with CTS to receive buffered or non-buffered mixtures of lidocaine and bupivacaine with epinephrine before CTR. The primary outcome is overall pain experienced during the injection of local anaesthetic, assessed with the Visual Analogue Scale. The secondary outcomes are pain intensity from the injection and during CTR, use of painkillers and pain intensity every 4 hours until third postoperative night, symptom severity and functional status preoperatively and at 3 months after surgery, and patient-rated outcome measures at 3 months after surgery. ETHICS AND DISSEMINATION This protocol was approved by the Research Ethics Committee of the Northern Savo Hospital District (2311/2021). The study will be performed according to the principles of good clinical practice and the Declaration of Helsinki. The results are expected to be presented in an international hand surgical conference and the manuscript to be sent to a hand surgery-orientated peer-reviewed journal during 2024. TRIAL REGISTRATION NUMBER This study is registered to clinicaltrials.gov, study ID NCT05328180.

Intra- and inter-observer agreement in distal radius fracture dislocation measurement of casting position. Acta Orthop 2023; 94:379-386. [PMID: 37493603 PMCID: PMC10370410 DOI: 10.2340/17453674.2023.13707] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2022] [Indexed: 07/27/2023] Open
Abstract
BACKGROUND AND PURPOSE Most displaced distal radius fractures (DRF) are treated nonoperatively, with reduction and immobilization in a cast. Studies assessing intra- or inter-observer agreement on radiologic measurements of casting position have not been published, which was the aim of our study. PATIENTS AND METHODS Our study is based on the Kuopio Osteoporosis Risk Factor and Prevention (OSTPRE) study. All detected DRFs during the OSTPRE follow-up were retrieved and based on sample size calculations 50 fractures were randomly selected for the study. 5 independent reviewers measured dislocation parameters and wrist position in a cast from the radiographs. A linear mixed model was used to estimate the concordance correlation coefficient (CCC) and total deviance index (TDI) that were used to evaluate intra- and inter-observer agreement. We used Kappa values to determine intra- and inter-rater agreement on radiographically acceptable reduction of the DRF. Limits of acceptable position were those defined by Finnish Current Care Guidelines. RESULTS For radial inclination, radial shortening, and dorsal/volar tilt, intra- and inter-observer correlations were high (CCC > 0.76). In addition, measurements of wrist angle in a splint had high correlations (CCC > 0.78), whereas measurement of intra-articular gap and step had poor correlations (CCC < 0.52). The Kappa value for overall agreement on the radiographically acceptable position of the DRF was modest (0.59). CONCLUSION Intra- and inter-observer repeatability of casting position of radial inclination, radial shortening, and dorsal/volar tilt were high whereas intra-articular gap and step had poor correlations.

Effectiveness of exercise on fall prevention in community-dwelling older adults: a 2-year randomized controlled study of 914 women. Age Ageing 2023; 52:7136744. [PMID: 37097767 PMCID: PMC10128158 DOI: 10.1093/ageing/afad059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/10/2022] [Indexed: 04/26/2023] Open
Abstract
BACKGROUND Communal exercise interventions may help prevent falls and injuries. However, pragmatic trials demonstrating the effectiveness of such strategies are sparse. METHODS We determined whether a cost-free 12-month admission to the city's recreational sports facilities including initial 6 months of supervised weekly gym and Tai Chi sessions decreases the number of falls and related injuries. The mean (SD) follow-up time was 22·6 (4.8) months in 2016-19. A total of 914 women from a population-based sample with a mean age of 76.5 (SD 3.3, range 71.1-84.8) years were randomized into exercise intervention (n = 457) and control (n = 457) groups. Fall information was collected through biweekly short message (SMS) queries and fall diaries. Altogether 1,380 falls were recorded for the intention-to-treat analysis, with 1,281 (92.8%) being verified by telephone. RESULTS A 14.3% fall rate reduction was detected in the exercise group (Incidence rate ratio (IRR) = 0.86; CI 95% 0.77-0.95) compared with the control group. Approximately half of the falls caused moderate (n = 678, 52.8%) or severe (n = 61, 4.8%) injury. In total, 13.2% (n = 166) of falls (including 73 fractures) required medical consultation with a 38% lower fracture rate in the exercise group (IRR = 0.62; CI 95% 0.39-0.99). Overall, the greatest reduction of 41% (IRR = 0.59; CI 95% 0.36-0.99) was observed in falls with severe injury and pain. CONCLUSIONS A community-based approach for a 6-month exercise period combined with a 12-month free use of sports premises can reduce falls, fractures and other fall-related injuries in aging women.

The impact of teacher's presence on learning basic surgical tasks with virtual reality headset among medical students. MEDICAL EDUCATION ONLINE 2022; 27:2050345. [PMID: 35262467 PMCID: PMC8920371 DOI: 10.1080/10872981.2022.2050345] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/04/2021] [Revised: 12/26/2021] [Accepted: 03/03/2022] [Indexed: 05/26/2023]
Abstract
BACKGROUND The aim of this study was to investigate whether the presence of a teacher affects learning related outcomes in teaching basic surgical tasks with a Virtual Reality (VR) headset. METHODS 26 fourth-year medical studentsparticipated in a voluntary exercise. Students practiced basic surgical procedure exercises using the VR4HEALTHCARE application in VR with OCULUS Rift S glasses. 12 students performed the exercises under the guidance of a teacher and 14 without the teacher present. After the exercise, the groups filled out a feedback form. Statistical analysis was performed using IBM SPSS Statistics 25.0 software using the Mann-Whitney U test and multivariate analysis of variance. RESULTS The most important data collected related to whether the student learned something new and whether VR adds value to medical education. Ratings were based on a scale of 0-10 (0 = worst, 10 = best). When the teacher was present, on average, the students felt that they were learning something new and gave an average rating of 7.8 ± 1.8, and when the teacher was not present 5.3 ± 2.6 (p = 0.003). VR added value to teaching with a rating of 7.8 ± 1.7 when the teacher was present and 5.5 ± 3.0 when not present (p = 0.045). This study also analyzed specific use of VR for abscess incision, suturing and insertion of a suprapubic catheter. DISCUSSION When a teacher was present VR added value to teaching and the usefulness and usability of VR was experienced more positively. The student should also have adequate knowledge of the subject to be taught before VR training. CONCLUSIONS VR adds value to teaching, but VR exercises may not completely replace high-quality traditional teaching methods. Consequently, it is important to determine the differences between VR and traditional teaching methods and how to combine these methods in the future.

Incidence and risk factors of spinal cord stimulation for persistent or recurrent pain after lumbar spine surgery: a population-based study. Acta Neurochir (Wien) 2022; 164:2645-2653. [PMID: 35713719 PMCID: PMC9519649 DOI: 10.1007/s00701-022-05268-w] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/04/2022] [Accepted: 06/01/2022] [Indexed: 01/26/2023]
Abstract
PURPOSE This study aims to elucidate the incidence of and independent risk factors for spinal cord stimulator implantations for patients who underwent lumbar spine surgery. METHODS The PERFormance, Effectiveness, and Cost of Treatment (PERFECT) episodes database, which was established for selected diseases and procedures in Finland, includes all patients who underwent lumbar spine surgery for degenerative spine conditions or spinal cord stimulation (SCS) in Finland from 1986 to 2018. The data on age, sex, hospital diagnoses, surgical procedures, and causes of death were imported from the Finnish national registers into the PERFECT database. RESULTS Between 1986 and 2018, 157,824 patients had their first lumbar spine procedure and for 1769 (1.1%) of them, a subsequent SCS procedure was observed during the follow-up. The cumulative incidence of SCS for persistent or recurrent pain after lumbar disk herniation, spinal stenosis, degenerative disk disease, and spondylolysis and spondylolisthesis surgery at 15 years was 1.2%, 1.0%, 2.7%, and 2.6% respectively. At 15 years, the cumulative incidence of SCS for persistent or recurrent pain after lumbar spine surgery after five or more lumbar spinal operations was 11.9%. CONCLUSION Repeated surgery was the most prominent significant risk factor for SCS for persistent or recurrent pain after lumbar spine surgery. The risk of SCS for persistent or recurrent pain after lumbar spine surgery increases significantly along with the number of lumbar spine procedures. When considering repeated lumbar spine surgery, careful evaluation of treatment options should take place to ensure good patient outcomes.

Abstract
The aim of this study was to monitor long-term changes in bone mineral density (BMD) after menopause and factors affecting BMD. The study population consisted of a random sample of 3222 women from the Kuopio Osteoporosis Risk Factor and Prevention (OSTPRE) study, of which 62.1% were postmenopausal at the beginning of the study. This group of women underwent dual-energy X-ray absorptiometry (DXA) measurements at the femoral neck every 5 years from baseline (in 1989) up to 25-year follow-up. They also responded to risk-factor questionnaires at 5-year intervals. During the 25-year follow-up, the baseline cohort decreased to 686 women. The women were divided into quartiles based on their baseline BMD. Self-reported hormone replacement therapy (HRT) and corticosteroid use were divided into ever users and never users. Morbidity was assessed as the total number of self-reported diseases and BMD-affecting diseases. The mean 25-year BMD change was found to be -10.1%, p < 0.001. Higher baseline BMD was associated with higher bone loss rate; the reduction in the highest quartile BMD was 11.1% and in the lowest quartile 7.4% (p = 0.0031). Lower baseline body mass index (BMI) and a greater increase in BMI were found to protect against postmenopausal bone loss (p < 0.001). The lowest bone loss quartile included 15.2% more HRT users than the highest bone loss quartile (p = 0.004). The number of diseases/bone-affecting diseases, use of vitamin D/calcium supplementation, use of corticosteroids, smoking or alcohol use had no statistical significance for annual bone loss rate. This study presents hitherto the longest (25-year) BMD follow-up in postmenopausal women. The linear femoral neck bone loss of 10% was less than previously assumed. A 5-year BMD change appeared to predict long-term bone loss in postmenopausal women. © 2021 The Authors.

Association between severe lumbar disc degeneration and self-reported occupational physical loading. J Occup Health 2022; 64:e12316. [PMID: 35084078 PMCID: PMC8793002 DOI: 10.1002/1348-9585.12316] [Citation(s) in RCA: 5] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/25/2021] [Revised: 01/07/2022] [Accepted: 01/12/2022] [Indexed: 11/16/2022] Open
Abstract
Objectives Occupational physical loading has been reported to be associated with intervertebral disc degeneration. However, previous literature reports inconsistent results for different vertebral levels. The aim of our study was to investigate the association between lumbar disc degeneration (LDD) at different vertebral levels and the self‐reported physical loading of occupation. Methods The study population consisted of 1,022 postmenopausal women and was based on the prospective Kuopio Osteoporosis Risk Factor and Prevention (OSTPRE) study cohort. The severity of LDD was graded from T2‐weighted MRI images using the five‐grade Pfirrmann classification. Five intervertebral levels (L1–L2 to L5–S1) were studied (total 5110 discs). The self‐rated occupational physical loading contained four groups: sedentary, light, moderate, and heavy. Results The heavy occupational physical loading group had higher odds for severe LDD at the L5–S1 vertebral level (OR 1.86, 95% CI: 1.19–2.92, p = .006) in comparison with the sedentary work group. A clear trend of increasing disc degeneration with heavier occupational loading was also observed at the L5–S1 level. Age, smoking, and higher body mass index (BMI) were associated with more severe LDD. Leisure‐time physical activity at the age of 11–17 years was associated with less severe LDD. Controlling for confounding factors did not alter the results. Conclusions There appears to be an association between occupational physical loading and severe disc degeneration at the lower lumbar spine in postmenopausal women. Individuals in occupations with heavy physical loading may have an increased risk for work‐related disability due to more severe disc degeneration.

Dietary omega-3 polyunsaturated fatty acid and alpha-linolenic acid are associated with physical capacity measure but not muscle mass in older women 65-72 years. Eur J Nutr 2021; 61:1813-1821. [PMID: 34913105 PMCID: PMC9106622 DOI: 10.1007/s00394-021-02773-z] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/23/2021] [Accepted: 12/06/2021] [Indexed: 12/02/2022]
Abstract
Purpose The aim was to investigate the cross-sectional association of dietary omega-3 polyunsaturated fatty acids PUFA (alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA)) intake with multiple physical functions, muscle mass and fat mass in older women. Method Study subjects were 554 women from the Osteoporosis Risk Factor and Prevention Fracture Prevention Study, with dietary intake assessed with 3-day food record. Body composition was measured by dual-energy X-ray absorptiometry. Physical function measures included walking speed 10 m, chair rises, one leg stance, knee extension, handgrip strength and squat. Short physical performance battery (SPPB) score was defined based on the European working group on sarcopenia criteria. Results The multivariable adjusted models showed statistically significant associations for dietary ALA with higher SPPB (β = 0.118, P = 0.024), knee extension force at baseline (β = 0.075, P = 0.037) and lower fat mass (β = − 0.081, P = 0.034), as well as longer one-leg stance (β = 0.119, P = 0.010), higher walking speed (β = 0.113, P = 0.047), and ability to squat to the ground (β = 0.110, P = 0.027) at baseline. Total dietary omega-3 PUFA was associated with better SPPB (β = 0.108, P = 0.039), one-leg stance (β = 0.102, P = 0.041) and ability to squat (β = 0.110, P = 0.028), and with walking speed (β = 0.110, P = 0.028). However, associations for dietary EPA and DHA with physical function and body composition were not significant. Conclusion Dietary omega-3 and ALA, but not EPA and DHA, were positively associated with muscle strength and function in older women. The intake of omega-3 and its subtypes was not associated with muscle mass. Longitudinal studies are needed to show whether omega-3 intake may be important for muscle function in older women.

Abstract
Background Physical capacity and subjective wellbeing are important for healthy aging. Our aim was to study how objective/subjective physical capacity and subjective health relate to life satisfaction, in a 10-year follow-up of aging women. Methods The participants (n = 1485, mean age 67.4 years) consisted of community-dwelling older women living in Kuopio, Finland. Grip strength and one-legged stance test time were used as objective, and self-rated mobility (SRM) as subjective physical capacity measures. Self-rated health (SRH) and SRM were assessed with one-item scales and life satisfaction with a 4-item scale. Correlation and linear regression were used to analyze these relationships and correlation network analysis to visualize them. Age and BMI were included in the analysis as adjusting factors. Results All the study variables were significantly correlated with baseline and follow-up life satisfaction, except BMI, which was only associated with life satisfaction at follow-up. On both occasions, SRH and SRM were the two strongest correlates of life satisfaction, but their mutual correlation was still higher. In linear regression analyses, SRH was positively associated with both baseline and follow-up life satisfaction, but physical capacity measures became non-significant after including SRH and SRM in the model. In the partial correlation network analyses, SRH and SRM were the most central nodes, connecting every other variable. Conclusions Self-reports on health, mobility, and life satisfaction are closely intertwined and provide easily accessible health information among aging women, but the impacts of objective physical capacity measures warrant further longitudinal studies in respect to subjective wellbeing among aging people.

Abstract
Background and purpose - There is lack of knowledge concerning patient-reported long-time outcome after arthroplasty. Therefore, we investigated patient self-reported physical capabilities (PC) and subjective well-being (SW) up to 20 years after total hip (THA) or knee (TKA) arthroplasty.Subjects and methods - The self-reports from postal questionnaires for study checkpoints (baseline, 10-year follow-up, 20-year follow-up) were provided by the Kuopio OSTPRE study including only women aged 52-62 years (n = 6,462). The Finnish Arthroplasty Register and Care Register for Health Care provided data on arthroplasties in the OSTPRE population. The results of women with THA/TKA were compared with women without arthroplasty (control group).Results - In subjects with THA performed before the 10-year follow-up, the proportion of good PC was initially decreased by 0.6 percentage points (pp) at the 10-year follow-up and later by 19 pp at the 20-year follow-up. After TKA, the proportion of subjects with good PC decreased by 4.1 pp (10-year follow-up) and 27 pp (20-year follow-up), respectively. The proportion of controls reporting good PC decreased by 1.4 pp at the 10-year follow-up and 14 pp at the 20-year follow-up compared with the baseline. After THA, the proportion of subjects with good SW stayed on the same level at 10-year follow-up and decreased by 2.3 pp at 20-year follow-up. After TKA, the proportion of good SW increased by 9.0 pp (10-year follow-up) and decreased by 14 pp (20-year follow-up). The proportion of controls reporting good SW increased by 4.0 pp (10-year follow-up) and decreased by 8.8 pp (20-year follow-up).Interpretation - THA and TKA maintain PC and SW. The overall PC and SW are lower in women with arthroplasty, in comparison with controls without arthroplasty. THA seems to outperform TKA in maintaining PC.

Abstract
Background and purpose - COVID-19 lockdowns have resulted in noteworthy changes in trauma admissions. We report and compare the incidence and characteristics of severe injuries (New Injury Severity Score [NISS] > 15) during the COVID-19 lockdown in Finland with earlier years.Methods - We retrospectively analyzed incidence rate, injury severity scores, injury patterns, and mechanisms of injury of all severely injured patients (NISS >15) in 4 Finnish hospitals (Tampere University Hospital, Kuopio University Hospital, Central Finland Hospital, Mikkeli Central Hospital) during the 11-week lockdown period (March 16-May 31, 2020) with comparison with a matching time period in earlier years (2016-2018). These 4 hospitals have a combined catchment area of 1,150,000 people or roughly one-fifth of the population of Finland.Results - The incidence rate of severe injuries during the lockdown period was 4.9/105 inhabitants (95% CI 3.7-6.4). The incidence rate of severe injuries during years 2016-2018 was 5.1/105 inhabitants (CI 3.9-6.5). We could not detect a significant incidence difference between the lockdown period and the 3 previous years (incidence rate difference -0.2 (CI -2.0 to 1.7). The proportion of traffic-related accidents was 55% during the lockdown period and 51% during previous years. There were no detectable differences in injury patterns. During the lockdown period, the mean age of patients was higher (53 years vs. 47 years, p = 0.03) and the rate of severely injured elderly patients (aged 70 or more) was higher (30% vs. 16%).Interpretation - Despite heavy social restrictions, the incidence of severe injuries during the lockdown period was similar to previous years. Notably, a decline in road use and traffic volumes did not reduce the number of severe traffic accidents. Although our data is compatible with a decrease of 2.0 to an increase of 1.7 severely injured patients per 105 inhabitants, we conclude that severely injured patients do not disappear even during pandemic and stabile hospital resources are needed to treat these patients.

Abstract
UNLABELLED Association of body mass index and hip fracture has been controversial. In this study, women with lowest and highest body weight had the highest fracture incidence. A 25-year follow-up indicated that obesity associates with early hip fracture risk and suggested increasing trend in normal-weight women at a later stage. INTRODUCTION Obesity is a pandemic health issue. Its association with hip fracture risk remains controversial. We studied the long-term relationship of body mass index and hip fracture incidence in postmenopausal women. METHODS The cohort of 12,715 Finnish women born in 1932-1941 was followed for 25 years, covering ages from 58 up to 83. Fractures and deaths were obtained from national registries. Women were investigated in deciles of BMI as well as in WHO weight categories (normal, overweight, or obese). The follow-up analysis was carried out in two age strata as "early" (58-70 years) and "late" (> 70 years). Body weight information was updated accordingly. Femoral neck BMD was recorded for a subsample (n = 3163). Altogether, 427 hip fractures were observed. RESULTS A higher risk of early hip fracture was observed in obese and normal-weight compared with overweight women with hazard ratios (HRs) of 2.3 ((95% CI) 1.4-3.7) and 2.0 (1.3-3.1) while no difference was observed in late hip fracture risk between the three WHO categories (log rank p = 0.14). All-cause mortality during the follow-up was 19.3%. Compared with normal weight women, the obese women had a higher risk of death with an HR of 1.6 (1.4-1.8) and higher baseline BMD (p < 0.001). Faster bone loss was observed in the obese compared with other women (p < 0.001). CONCLUSION Obesity associates with earlier hip fracture and higher postfracture mortality. The obese women with low BMD have clearly the highest risk of hip fracture. This combination increases hip fracture risk more than either of the factors alone. After 75 years of age, risk appears to increase more in normal weight women, but this trend is in need of further confirmation.

Abstract
Aims There is evidence that prior lumbar fusion increases the risk of dislocation and revision after total hip arthroplasty (THA). The relationship between prior lumbar fusion and the effect of femoral head diameter on THA dislocation has not been investigated. We examined the relationship between prior lumbar fusion or discectomy and the risk of dislocation or revision after THA. We also examined the effect of femoral head component diameter on the risk of dislocation or revision. Methods Data used in this study were compiled from several Finnish national health registers, including the Finnish Arthroplasty Register (FAR) which was the primary source for prosthesis-related data. Other registers used in this study included the Finnish Health Care Register (HILMO), the Social Insurance Institutions (SII) registers, and Statistics Finland. The study was conducted as a prospective retrospective cohort study. Cox proportional hazards regression and Kaplan-Meier survival analysis were used for analysis. Results Prior lumbar fusion surgery was associated with increased risk of prosthetic dislocation (hazard ratio (HR) = 2.393, p < 0.001) and revision (HR = 1.528, p < 0.001). Head components larger than 28 mm were associated with lower dislocation rates compared to the 28 mm head (32 mm: HR = 0.712, p < 0.001; 36 mm: HR = 0.700, p < 0.001; 38 mm: HR = 0.808, p < 0.140; and 40 mm: HR = 0.421, p < 0.001). Heads of 38 mm (HR = 1.288, p < 0.001) and 40 mm (HR = 1.367, p < 0.001) had increased risk of revision compared to the 28 mm head. Conclusion Lumbar fusion surgery was associated with higher rate of hip prosthesis dislocation and higher risk of revision surgery. Femoral head component of 32 mm (or larger) associates with lower risk of dislocation in patients with previous lumbar fusion. Cite this article: Bone Joint J 2020;102-B(8):1003–1009.

Abstract
INTRODUCTION Falls are a substantial health problem in seniors, causing fractures and being the leading cause of fatal injuries. The benefits of physical activity in fall prevention have been shown in randomised controlled trials (RCTs) in small cohorts (eg, ≤200 persons), but there is a gap between the known health effects of exercise and the large-scale implementation of effective activity in communities. Mental health and subjective well-being (SWB) should also be studied since they are strongly related to healthy ageing. Thus far, the proven efficacy of communal strategies to reduce falls and improve healthy ageing is sparse. METHODS AND ANALYSIS In 2016, a 2-year RCT was launched in Kuopio, Finland to estimate the efficacy of a large, population-based, fall prevention exercise programme in community-living older women (born 1932-1945). Both the intervention and control group (n=457+457) receive health education. The intervention group is also offered free 6-month supervised training courses (weekly gym training and Taiji sessions), followed by a free 6-month unsupervised use of exercise facilities, as well as unsupervised low-cost exercise is also offered for another 12 months. During the whole 24-month follow-up, controls are free to pursue all their normal physical activities. Both study groups undergo the study measurements three times. Outcome measures include recording of falls, injuries, bone mineral density, changes in health and functional status and cognitive performance, deaths and SWB. Finally, the cost-effectiveness and cost-utility analysis will be conducted from the societal view. The main analyses comparing outcomes between study groups will be conducted using the intention to treat principle. ETHICS AND DISSEMINATION The study has been reviewed and approved by the Research Ethics Committee of the Hospital District of North Savo. All regulations and measures of ethics and confidentiality are handled in accordance with the Declaration of Helsinki. TRIAL REGISTRATION NUMBER NCT02665169; Pre-results.

Abstract
The aim of this prospective cohort study was to investigate the independent effect of postural sway on overall fracture and osteoporotic fracture risk after controlling for other established fracture risk factors. As a secondary outcome, mortality was also investigated. The study sample is a stratified random sample of 1568 women born between 1932 and 1941, residing in Kuopio province, eastern Finland. Fracture data were obtained through study questionnaires and verified through hospital records. Mortality data were verified through the National Registry. Using static posturography, postural sway was recorded for 1568 women at the fifth year of follow-up in 1994 through 1997. Mediolateral (ML), anteroposterior (AP), and total sway parameters were used for analysis. Mean follow-up time for any fractures, osteoporotic fractures, and mortality was 10.6, 11.4, and 17.5 years, respectively. After adjustment, subjects in the highest quartile of ML sway (HR, 2.0; 95% CI, 1.5 to 2.8) and total sway (HR, 1.6; 95% CI, 1.2 to 2.2) had a higher risk for any fracture. Osteoporotic fracture risk was also higher in the fourth quartile of ML sway (HR, 1.9; 95% CI, 1.1 to 3.0) and total sway (HR, 1.7; 95% CI, 1.0 to 2.8). The models were adjusted for fracture risk assessment tool risk factors and leg-extension strength. Further, women having both lowest bone density and highest postural sway were at 4.9 (95% CI, 2.6 to 9.5) times higher risk of overall fracture and 11.8 (95% CI, 2.7 to 51.3) times higher risk for osteoporotic fracture in comparison with subjects having highest bone density and lowest postural sway. The association between postural sway and mortality was not significant after adjustment. In conclusion, high postural sway is an independent risk factor for any fractures as well as for osteoporotic fractures. A combination of low bone density and high postural sway poses even higher fracture risk than either factor alone. Postural sway does not predict mortality independently. © 2019 American Society for Bone and Mineral Research.

Abstract
UNLABELLED Our findings imply that simple functional tests can predict both hip fracture risk and excess mortality in postmenopausal women. Since the tests characterize general functional capacity (one-legged stance, squatting down, and grip strength), these simple measures should have clinical utility in the assessment of women at risk of falls and fragility fracture. INTRODUCTION Functional impairment is associated with the risk of fall, which is the leading cause of hip fracture. We aimed to determine how clinical assessments of functional impairment predict long-term hip fracture and mortality. METHODS A population-based prospective cohort involved 2815 Caucasian women with the average baseline age of 59.1 years. The mean follow-up time in 1994-2014 was 18.3 years. Three functional tests and their combinations assessed at baseline were treated as dichotomous risk factors: (1) inability to squat down and touch the floor (SQ), (2) inability to stand on one leg for 10 s (SOL), and (3) having grip strength (GS) within the lowest quartile (≤ 58 kPa, mean 45.6 kPa). Bone mineral density (BMD) at the proximal femur was measured by DXA. Fractures and deaths were verified from registries. Hazard ratios were determined by using Cox proportional models. Age, body mass index (BMI), and BMD were included as covariates for fracture risk estimates. Age, BMI, and smoking were used for mortality. RESULTS Altogether, 650 (23.1%) women had 718 follow-up fractures, including 86 hip fractures. The mortality during the follow-up was 16.8% (n = 473). Half of the women (56.8%, n = 1600) had none of the impairments and were regarded as the referent group. Overall, women with any of the three impairments (43.2%, n = 1215) had higher risks of any fracture, hip fracture, and death, with hazard ratios (HR) of 1.3 ((95% CI) 1.0-1.5, p < 0.01), 2.4 (1.5-3.4, p < 0.001), and 1.5 (1.3-1.8, p < 0.001), respectively. The strongest single predictor for hip fracture was failing to achieve a one-leg stand for 10 s (prevalence 7.1%, n = 200), followed by inability to squat down (27.0%, n = 759) and weak grip strength (24.4%, n = 688), with their respective HRs of 4.3 (2.3-8.0, p < 0.001), 3.1 (2.0-5.0, p < 0.001), and 2.0 (1.2-3.4, p < 0.001). In addition, age, lower BMD, BMI, and smoking were significant covariates. CONCLUSIONS These findings suggest that functional tests provide long-term prediction of fracture and death in postmenopausal women. Whether reversal of these impairments is associated with a reduction in adverse outcomes is an area for future trials.

Abstract
OBJECTIVES 1) To study if limb length explains variability in appendicular and total muscle mass better than height and 2) if muscle mass adjusted for limb length rather than height correlates better with grip and knee extension strength. METHODS 400 healthy women aged 20-40 were recruited as a reference population. Body composition, limb length, grip strength and knee extension strength were measured. New relative muscle mass indexes were computed by adjusting upper limb muscle mass for upper limb length (ULRSMI) and lower limb muscle mass for lower limb length (LLRSMI). RESULTS Height correlated strongest with all muscle mass measures. Height had the highest R² values for predicting variability in appendicular skeletal muscle mass (0.33), upper limb skeletal muscle mass (0.20), lower limb skeletal muscle mass (0.34) and total skeletal muscle mass (0.36). Correlation of relative skeletal muscle mass index (RSMI) with grip and knee extension strength (r=0.47 and 0.43) was higher when compared with correlation of ULRSMI and LLRSMI with these measures. CONCLUSION Compared to limb length, height correlates better with regional and total muscle mass. Muscle mass adjusted for height correlates better with grip strength and knee strength when compared with muscle mass adjusted for limb length.

Dietary fatty acids were not independently associated with lipoprotein subclasses in elderly women. Nutr Res 2017; 43:60-68.

Abstract
Dietary fatty acids are known to affect serum lipoproteins; however, little is known about the associations between consumption of dietary fatty acids and lipoprotein subclasses. In this study, we hypothesized that there is an association between dietary fatty acids and lipoprotein subclasses and investigated the cross-sectional association of dietary fat intake with subclasses of lipoproteins in elderly women. Altogether, 547 women (aged ≥65 years) who were part of OSTPRE cohort participated. Dietary intake was assessed by 3-day food records, lifestyle, and health information obtained through self-administrated questionnaires, and lipoprotein subclasses were determined by nuclear magnetic resonance spectroscopy. To analyze the associations between fatty acids and lipoprotein subclasses, we used Pearson and Spearman correlation coefficients and the analysis of covariance (ANCOVA) test with, adjustment for physical activity, body mass index, age, smoking status, and intake of lipid-lowering drugs. There were significant correlations between saturated fatty acids (SFA; % of energy) and concentrations of large, medium, and small low-density lipoproteins (LDL); total cholesterol in large, medium, and small LDL; and phospholipids in large, medium, and small LDL, after correction for multiple testing. After adjustment for covariates, the higher intake of SFA was associated with smaller size of LDL particles (P = .04, ANCOVA) and lower amount of triglycerides in small very low-density lipoproteins (P = .046, ANCOVA). However, these associations did not remain significant after correction for multiple testing. In conclusion, high intake of SFA may be associated with the size of LDL particles, but the results do not support significant, independent associations between dietary fatty acids and lipoprotein subclasses.

Abstract
It has been hypothesized that high protein intakes are associated with lower bone mineral content (BMC). Previous studies yield conflicting results and thus far no studies have undertaken the interaction of body mass index (BMI) and physical activity with protein intakes in relation to BMC and bone mineral density (BMD). OBJECTIVE To evaluate the associations of dietary total protein (TP), animal protein (AP) and plant protein (PP) intakes with BMC and BMD and their changes. We tested also the interactions of protein intake with, obesity (BMI ≤30 vs. >30 kg/m2) and physical activity level (passive vs. active). Design/ Setting: Prospective cohort study (Osteoporosis Risk-Factor and Fracture-Prevention Study). Participants/measures: At the baseline, 554 women aged 65-72 years filled out a 3-day food record and a questionnaire covering data on lifestyle, physical activity, diseases, and medications. Intervention group received calcium 1000 mg/d and cholecalciferol 800 IU for 3 years. Control group received neither supplementation nor placebo. Bone density was measured at baseline and year 3, using dual energy x-ray absorptiometry. Multivariable regression analyses were conducted to examine the associations between protein intake and BMD and BMC. RESULTS In cross-sectional analyses energy-adjusted TP (P≤0·029) and AP (P≤0·045) but not PP (g/d) were negatively associated with femoral neck (FN) BMD and BMC. Women with TP≥1·2 g/kg/body weight (BW) (Ptrend≤0·009) had lower FN, lumbar spine (LS) and total BMD and BMC. In follow-up analysis, TP (g/kg/BW) was inversely associated with LS BMD and LS BMC. The detrimental associations were stronger in women with BMI<30 kg/m2. In active women, TP (g/kg/BW) was positively associated with LS BMD and FN BMC changes. CONCLUSIONS This study suggests detrimental associations between protein intake and bone health. However, these negative associations maybe counteracted by BMI>30 kg/m2 and physical activity.

Abstract
The timing of the menopause transition has remained fairly constant throughout history. It represents a milestone in female health and, after passing through it, women experience increased musculoskeletal and cardiovascular morbidity. Muscle performance is an important determinant of functional capacity and quality of life among the elderly and is also involved in the maintenance of balance. Therefore, good muscle strength can prevent fragility fractures and lessen the burden of osteoporosis. Muscle strength begins to decline during the perimenopausal years and this phenomenon seems to be partly estrogen dependent. Randomized controlled trials have indicated that hormone replacement therapy may prevent a decline in muscle performance, although the exact mechanism of estrogen-dependent sarcopenia remains to be clarified. Exercises have been shown to improve postmenopausal muscle performance and hormone replacement therapy may also potentiate these beneficial effects. Improvement or maintenance of muscle strength alone, however, may not be considered as a primary indication for long-term hormone replacement therapy in view of current knowledge of its risks and benefits. Work history and educational background may be associated with postmenopausal muscle performance, which itself has unique associations with skeletal and cardiovascular diseases.

Abstract
PURPOSE To investigate the relationships of severe health disorders (SHD) with bone loss, grip strength (GS) and mobility in postmenopausal women. METHOD The study sample consisted of 2227 Finnish women (mean age 53.2) from the Kuopio Osteoporosis Risk Factor and Prevention (OSTPRE) cohort. Postal inquiries and clinical measurements were completed during the 15-year follow-up at 5-year intervals between 1989 and 2004. Femoral neck bone mineral density (BMD) and GS were measured. Life-style factors and mobility were obtained via postal inquiries. Work disability pension according to the ICD-9 was an indicator of a SHD. RESULTS At the baseline 242 women had SHD, 506 got late SHD during 1989-1995, whereas 1479 women had none until 1996. The women with baseline SHD had higher annual bone loss (0.44%) than those without SHD (0.34%) (p < 0.05), those with late SHD (0.39%) no difference was seen. Bone loss was highest with respiratory diseases, but BMD was lowest throughout the follow-up in nervous and sense organ diseases. Lower GS and mobility was also associated with SHD. CONCLUSION Effects of SHDs on BMD, GS, and mobility are disease-specific. Thus, rehabilitation should be encouraged in postmenopausal women with SHD, especially in case of diseases of respiratory and nervous system. Implications for Rehabilitation Osteoporosis, muscle strength and co-morbidity Women with severe health disorders (SHD) leading to work disability have impaired musculoskeletal health. Active monitoring of the musculoskeletal health is advised for those with SHD. Women with SHD may benefit from rehabilitative treatment in order to avoid complications of musculoskeletal impairments.

Abstract
OBJECTIVES Higher vertebral bone mineral density (BMD) has been found to be related with lumbar disc degeneration (LDD), while relationship between femoral neck BMD and LDD remains controversial. The aim of our research was to study the relationship between LDD and BMD of the lumbar spine and femoral neck. STUDY DESIGN The study population consisted of 168 postmenopausal women (aged 63.3-75.0 years, mean 68.6 years) from the prospective OSTPRE and OSTPRE-FPS study cohorts. The severity of LDD was graded from T2-weighted MRI images using the five-grade Pfirrmann classification. Four vertebral levels (L1-L4) were studied (total 672 discs). The association between lumbar BMD and Z-score and the severity of LDD was studied separately for each vertebral level with AN(C)OVA analysis, using potential confounders as covariates. RESULTS Higher lumbar BMD and Z-score were associated with more severe LDD at all studied levels (L1-L4): between L4-L5 disc and L4 BMD (p=0.044) and L4 Z-score (p=0.052), between L2-L3 disc and L3 BMD (p=0.001) and at all other levels (p<0.001). The mean degeneration grade of the studied discs was associated with the mean L1-L4 BMD and Z-score (p<0.001). Statistical significance of any result did not alter after controlling for confounding factors. There was no significant association between femoral neck BMD and LDD. CONCLUSIONS Higher lumbar BMD/Z-score were associated with more severe LDD. There was no significant association between femoral neck BMD and disc degeneration. Femoral neck BMD may be a more reliable measurement for diagnosing osteoporosis in postmenopausal women with degenerative changes in the lumbar spine.

In vivo diagnostics of human knee cartilage lesions using delayed CBCT arthrography. J Orthop Res 2014; 32:403-12.

Abstract
The aim of this study was to investigate the feasibility of delayed cone beam (CBCT) arthrography for clinical diagnostics of knee cartilage lesions. Knee joints with cartilage lesions were imaged using native radiography, MRI, and delayed CBCT arthrography techniques in vivo. The joints were imaged three times with CBCT, just before, immediately after (arthrography) and 45 min after the intra-articular injection of contrast agent. The arthrographic images enabled sensitive detection of the cartilage lesions. Use of arthrographic and delayed images together with their subtraction image enabled also detection of cartilage with inferior integrity. The contrast agent partition in intact cartilage (ICRS grade 0) was lower (p < 0.05) than that of cartilage surrounding the ICRS grade I-IV lesions. Delayed CBCT arthrography provides a novel method for diagnostics of cartilage lesions. Potentially, it can also be used in diagnostics of cartilage degeneration. Due to shorter imaging times, higher resolution, and lower costs of CT over MRI, this technique could provide an alternative for diagnostics of knee pathologies. However, for comprehensive evaluation of the clinical potential of the technique a further clinical study with a large pool of patients having a wide range of cartilage pathologies needs to be conducted.

Abstract
The incidence of severe sepsis and septic shock requiring intensive care in Finnish adult population has increased to 0.60 11000 /y. Despite improved prognosis, hospital mortality related to severe sepsis and septic shock is high 24.1%. Key recommendations include prompt administration of antimicrobial therapy, optimally after blood cultures, quantitative fluid resuscitation and imaging studies to identify possible source of infection. Crystalloids are suitable for fluid resuscitation. Norepinephrine is the first-choice vasopressor in septic shock. Hydrocortisone should be considered only if fluid and vasopressor treatment does not restore hemodynamics.

Relationship between postmenopausal osteoporosis and the components of clinical sarcopenia. Maturitas 2013; 75:175-80. [PMID: 23628279 DOI: 10.1016/j.maturitas.2013.03.016] [Citation(s) in RCA: 140] [Impact Index Per Article: 12.7] [Reference Citation Analysis] [Abstract] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/17/2012] [Revised: 03/21/2013] [Accepted: 03/25/2013] [Indexed: 01/11/2023]
Abstract
PURPOSE The aim of the study was to determine the relationship between the components of clinical sarcopenia and osteoporosis in postmenopausal women. METHODS A population-based cohort of 590 Finnish postmenopausal women (mean age 67.9; range 65-72) was selected from the Osteoporosis Fracture Prevention (OSTPRE-FPS) study in 2002. Bone mineral density (BMD) and lean tissue mass were assessed by dual X-ray absorptiometry (DXA). The study sample was divided into three categories according to the WHO BMD classification: normal, osteopenia and osteoporosis. The study sample was divided into non-sarcopenic, presarcopenic, sarcopenic and non-classified groups according to quartiles of RSMI i.e. relative skeletal muscle index (appendicular muscle mass (kg)/square of height (m)), hand grip strength (kPa) and walking speed. RESULTS In logistic regression analysis sarcopenic women had 12.9 times higher odds of having osteoporosis (p ≤ 0.001, OR=12.9; 95% CI=3.1-53.5) in comparison to non-sarcopenic women. In comparison to women in the highest grip strength quartile, women within the lowest quartile had 11.7 times higher odds of having osteoporosis (p=0.001, OR=11.7; 2.6-53.4). Sarcopenic women had 2.7 times higher odds of having fractures than their non-sarcopenic counterparts (p=0.005, OR=2.732; 1.4-5.5). Sarcopenic women had also 2.1 times higher risk of falls during the preceding 12 months compared to non-sarcopenic women (p=0.021, OR=2.1; 1.1-3.9). Adjustment for age, body mass index (BMI), physical activity and hormone therapy (HT) did not significantly alter these results. CONCLUSIONS The components of clinical sarcopenia are strongly associated with osteoporosis. Grip strength is the most significant measurement to reveal the association between sarcopenia and osteoporosis, falls and fractures.

Abstract
Repetitive strain injuriesof the upper extremities refer to pain in the forearm, wrist and hand, caused by excessive strain. Diagnoses include tenosynovitis, epicondylitis and carpal tunnel syndrome. Treatment is aimed at alleviating pain, restoring normal physical functioning and maintain ability to work. Preventive interventions have shown some attenuation of discomfort but no effects on disease prevalance or sick leave days. Return to work interventions seem to decrease length of sickness absences. Part time work has hastened return to work and decreased sickness absences in musculoskeletal disorders.

Muscle strength and body composition are clinical indicators of osteoporosis. Calcif Tissue Int 2012; 91:131-8. [PMID: 22733383 DOI: 10.1007/s00223-012-9618-1] [Citation(s) in RCA: 70] [Impact Index Per Article: 5.8] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/08/2012] [Accepted: 05/15/2012] [Indexed: 11/24/2022]
Abstract
We examined the role of muscle strength, lean tissue distribution, and overall body composition as indicators of osteoporosis (OP) in a pooled sample of 979 Finnish postmenopausal women (mean age 68.1 years) from the Kuopio Osteoporosis Risk Factor and Prevention study. Bone mineral density (BMD) at the femoral neck (FN) and total body composition were assessed by dual-energy X-ray absorptiometry scans. The women (n = 979) were divided into three groups according to WHO criteria, based on FN BMD T score: normal (n = 474), osteopenia (n = 468), and OP (n = 37). Soft tissue proportions, fat mass index (FMI, fat/height²), lean mass index (LMI, lean/height²), and appendicular skeletal muscle mass (ASM, (arms + legs)/height²) were calculated. Handgrip and knee extension strength measurements were made. OP subjects had significantly smaller LMI (p = 0.001), ASM (p = 0.001), grip strength (p < 0.0001), and knee extension strength (p < 0.05) but not FMI (p > 0.05) compared to other subjects. Grip and knee extension strength were 19 and 16 % weaker in OP women compared to others, respectively. The area under the receiver operating characteristic curve was 69 % for grip and 71 % for knee extension strength. In tissue proportions only LMI showed predictive power (63 %, p = 0.016). An overall linear association of LMI (R² = 0.007, p = 0.01) and FMI (R² = 0.028, p < 0.001) with FN BMD remained significant. In the multivariate model, after adjusting for age, grip strength, leg extension strength, FMI, LMI, number of medications, alcohol consumption, current smoking, dietary calcium intake, and hormone therapy, grip strength (adjusted OR = 0.899, 95 % CI 0.84-0.97, p < 0.01), leg extension strength (OR = 0.998, 95 % CI 0.99-1, p < 0.05), and years of hormone therapy (OR = 0.905, 95 % CI 0.82-1, p < 0.05) remained as significant determinants of OP. Muscle strength tests, especially grip strength, serve as an independent and useful tool for postmenopausal OP risk assessment. In addition, lean mass contributes to OP in this age group. Muscle strength and lean mass should be considered separately since both are independently associated with postmenopausal BMD.

Abstract
OBJECTIVE To explore the association of frailty according to questionnaire data (modified Fried criteria) with important endpoints in older men. DESIGN AND SETTING Prospective cohort study (the Helsinki Businessmen Study) in Finland. PARTICIPANTS AND MEASUREMENTS In 1974, clinically healthy men (born 1919-1934, n=1815) of similar socioeconomic status were identified. After a 26-year follow-up in 2000 (mean age 73 years), disease prevalence, mobility-disability, and frailty status (80.9% of survivors, n=1125) were appraised using a postal questionnaire including RAND-36. Four criteria were used for definition: 1) >5% weight loss from midlife, or body mass index (BMI) <21 kg/m2; 2) reported physical inactivity; 3) low vitality (RAND-36); 4) physical weakness (RAND-36). Responders with 3-4, 1-2, and zero criteria were classified as frail (n=108), prefrail (n=567), and nonfrail (n=450), respectively. Eight-year mortality was assessed from registers, and in 2007, survivors were re-assessed with questionnaires. RESULTS Nonfrail as referent and adjusted for age, BMI and smoking, both prefrail (HR 2.26; 95% CI, 1.57-3.26), and frail status (4.09; 95% CI, 2.60-6.44) were significant predictors of mortality. Nonfrailty predicted better survival independently of the frailty components, diseases, and disability, and also predicted faster walking speed and less disability 7 years later. CONCLUSIONS Frailty, and also prefrailty, as defined using questionnaire data (RAND-36) independently predicted important endpoints in older men.

Abstract
Postmenopausal population is at increased risk of musculoskeletal impairments. Sarcopenia and osteoporosis are associated with significant morbidity and social and health-care costs. These two conditions are uniquely linked with similarities in pathophysiology and diagnostic methods. Uniform diagnostic criteria for sarcopenia are still evolving. Postmenopausal sarcopenia and osteoporosis share many environmental risk- and preventive factors. Moreover, geriatric frailty syndrome may result from interaction of osteoporosis and sarcopenia and may lead to increased mortality. The present paper reviews the factors in evolution of postmenopausal sarcopenia and osteoporosis.

Abstract
OBJECTIVE We tested whether an intra-articular ultrasound (IAUS) method could be used to evaluate cartilage status arthroscopically in human knee joints in vivo. DESIGN Seven patients undergoing arthroscopic surgery of the knee were enrolled in this study. An ultrasonic examination was conducted using the same portals as in the arthroscopic surgery. A high-frequency (40-MHz) ultrasound transducer (diameter = 1 mm) was directed to the desired location on the articular surface under arthroscopic control. In addition to ultrasound data, an IAUS video and optical video through the arthroscope were recorded. Classification of cartilage injuries according to International Cartilage Repair Society, as conducted by the orthopedic surgeon, provided reference data for comparison with the IAUS. RESULTS The IAUS method was successful in imaging different characteristics of the articular surfaces (e.g., intact surface, surface fibrillation, and lesions of varying depth). In some cases, also the subchondral bone and abnormal internal cartilage structure were visible in the IAUS images. Specifically, using the IAUS, a local cartilage lesion of 1 patient was found to be deeper than estimated arthroscopically. CONCLUSIONS The IAUS method provided a novel arthroscopic method for quantitative imaging of articular cartilage lesions. The IAUS provided quantitative information about the cartilage integrity and thickness, which are not available in conventional arthroscopy. The present equipment is already approved by the Food and Drug Administration for intravascular use and might be transferred to intra-articular use. The invasiveness of the IAUS method might restrict its wider clinical use but combined with arthroscopy, ultrasonic assessment may enlarge the diagnostic potential of arthroscopic surgery.

Abstract
UNLABELLED The present study investigated the bone health related factors that were associated with the use of bisphosphonates (BP) among 2,050 postmenopausal Finnish women. Low BMD + low trauma energy fracture was the strongest determinant of BP use, while other secondary causes of osteoporosis were less strongly related with BP use. BP use was associated with reduced femoral neck (FN) and lumbar spine (LS) bone loss rate. INTRODUCTION The aim was to identify bone health related factors associated with the use of BP in a community setting. METHODS A population-based sample of 2,050 Finnish postmenopausal women was measured with dual X-ray absorptiometry at the FN and LS in 1989, 1994, 1999 and 2004, and information on osteoporosis risk factors, including low-trauma energy fractures, were collected with postal inquiries. Self-reported use of BP in 2004 was considered as the end point variable. RESULTS Among BP users, 12% had T-score > -2.0 SD and no fracture during follow-up (FU). In women without any bone medication, 26% had T-score < -2.0 SD or low-trauma energy fracture or both during the FU. In BP users, a significant reduction in FN and LS bone loss rate, cumulative with duration of use, was observed in ANCOVA (p < 0.001). Among BP users, there was a significantly higher proportion of women with several independent risk factors for osteoporosis and more spine and humerus fractures but less ankle fractures. T-score < -2 SD combined with low-trauma energy fracture was significantly related to the use of BPs (p < 0.001, OR = 15.96) and T-score < -2 SD was a stronger predictor of BP use (p < 0.001, OR = 13.29) than fracture (p > 0.05, OR = 1.35) in multivariate logistic regression. Other factors related with BP use were vitamin D use (p = 0.001, OR = 2.27), high number of medications (p < 0.001, OR = 1.26) and rheumatoid arthritis (p < 0.05, OR 2.55). CONCLUSIONS These findings reveal the recent bone health-related indications for BP prescription.

Abstract
SUMMARY The Osteoporosis Risk Factor and Prevention-Fracture Prevention Study (OSTPRE-FPS) was a randomized population-based open trial (n = 593). The supplementation group (n = 287) received daily cholecalciferol 800 IU + calcium 1,000 mg for 3 years while the control group (n = 306) received neither supplementation nor placebo. Daily vitamin D and calcium supplementation have a positive effect on the skeleton in ambulatory postmenopausal women. INTRODUCTION vitamin D deficiency is common in the elderly, and vitamin D levels are associated with low bone mineral density (BMD). The working hypothesis was that vitamin D and calcium supplementation could prevent bone loss in ambulatory postmenopausal women. METHODS the OSTPRE-FPS was a randomized population-based open trial with a 3-year follow-up in 3,432 women (aged 66 to 71 years). A randomly selected subsample of 593 subjects underwent BMD measurements. The supplementation group (n = 287) received daily cholecalciferol 800 IU + calcium 1,000 mg for 3 years while the control group (n = 306) received neither supplementation nor placebo. RESULTS in the intention-to-treat analysis, total body BMD (n = 362) increased significantly more in the intervention group than in the control group (0.84% vs. 0.19%, p = 0.011). The BMD change differences at the lumbar spine (p = 0.372), femoral neck (p = 0.188), trochanter (p = 0.085), and total proximal femur (p = 0.070) were statistically nonsignificant. Analyses in compliant women (≥ 80% of use) resulted in stronger and statistically significant effects at the total body and femoral regions. CONCLUSION daily vitamin D and calcium supplementation have a positive effect on the skeleton in ambulatory postmenopausal women with adequate nutritional calcium intake.

Abstract
Results on fracture risk among physically active persons are contradictory. The aim of this study was to investigate the long-term association between the self-reported physical activity (PA), the risk of fractures, and bone loss among peri- and postmenopausal women. The association between PA and fracture risk was examined during 15 years of follow-up in the population-based Osteoporosis Risk Factor and Prevention (OSTPRE) Study among 8560 women with a mean age of 52.2 years (range 47 to 56 years) at baseline. The amount and type of PA, as well as the types and mechanisms of fractures, were registered with self-administered questionnaires at 5-year intervals (ie, 1989, 1994, 1999, and 2004). A total of 2641 follow-up fractures were verified in 2073 women (24.2%). The study cohort was divided into quartiles by average hours of reported PA during the whole follow-up. Areal bone mineral density (aBMD) at the proximal femur (n = 2050) and lumbar spine (L(2)-L(4); n = 1417) was followed at 5-year intervals from a random stratified subsample with dual X-ray absorptiometry (DXA). Risk of fracture was estimated by using the Cox proportional hazards model with a mean follow-up time of 15.2 years. Weekly average time spent on leisure-time PA was 0.4, 1.7, 3.3, and 7.0 hours from the least to the most active quartiles, respectively. The risk of wrist fracture was higher in the active quartiles (II to IV) than in the most inactive quartile (I), with hazard ratios (HRs) of 1.3 [95% confidence interval (CI) 1.05-1.57, p = .014] for the second (II), 1.2 (95% CI 1.01-1.51, p = .045) for the third (III), and 1.4 (95% CI 1.14-1.69, p = .001) for the fourth (IV) quartile, respectively. Overall, most of the fractures were reported as a result of a fall (69.0%), with a 2.1 times higher rate of wrist fractures during the winter (November to April) than during summer season. There were no significant associations of PA with any other fracture types. Bone loss at the femoral neck, trochanter, and Ward's triangle was significantly associated with long-term PA (ANCOVA p < .05), whereas no associations of bone loss and PA in lumbar spine were seen. PA is associated with a moderate rise in wrist fracture risk, which might be explained in part by a higher number of outdoor activities. Regular PA of at least 1½ hours per week does not seem to increase the risk of other fractures and might significantly decrease proximal femur bone loss among peri- and postmenopausal women.

Abstract
Antifracture efficacy of high-dose vitamin D (800 IU) and calcium (1000 mg) remains controversial. To determine whether daily 800 IU of vitamin D and 1000 mg of calcium supplementation prevents fractures, we randomized 3432 women of the population-based Osteoporosis Risk Factor and Prevention (OSTPRE) Study cohort (ages 65 to 71 years) living in the region of northern Savonia, Finland (latitude 62 degrees to 64 degrees N) for 3 years to receive 800 IU of cholecalciferol and 1000 mg of calcium as calcium carbonate or to a control group that did not receive placebo. The main outcome measure was incident fractures. Fracture data were collected in telephone interviews and validated. Data on 3195 women, 1586 in the intervention group and 1609 in the control group, were available for analysis. In adjusted Cox proportional hazards models, the risk of any fracture decreased in the vitamin D and calcium group by 17% [adjusted hazard ratio (aHR) = 0.83; 95% confidence interval (CI) 0.61-1.12], and the risk of any nonvertebral fracture decreased by 13% (aHR = 0.87; 95% CI 0.63-1.19). The risk of distal forearm fractures decreased by 30% (aHR = 0.70; 95% CI 0.41-1.20), and the risk of any upper extremity fractures decreased by 25% (aHR = 0.75; 95% CI 0.49-1.16), whereas the risk of lower extremity fractures remained essentially equal (aHR = 1.02; 95% CI 0.58-1.80). None of these effects reached statistical significance. In conclusion, this study did not produce statistically significant evidence that vitamin D and calcium supplementation prevents fractures in a 65- to 71-year-old general population of postmenopausal women.

Abstract
Aim was to investigate fracture risk (FR) according to bone loss (BL) rate. A random sample of 1652 women aged 53.5 years was measured with dual X-ray absorptiometry in femoral neck in 1989 and 1994 and divided into tertiles of annual BL rate: high >0.84%, moderate 0.13%-0.84%, and low <0.13%. Low trauma energy fractures during following 10 years were recorded. There were no differences in FR between BL tertiles in Cox regression model. Factors predicting lower FR in Cox model were in high tertile: high T-score (HR 0.71; 95% CI 0.54-0.93, P = .012), no sister's fracture (HR 0.35; 0.19-0.64, P = .001), no mother's fracture (HR 0.52; 0.31-0.88, P = .015), in moderate tertile: high T-score (HR 0.69;0.53-0.91, P = .008) and good grip strength (HR 0.98; 0.97-0.99, P = .022). In low tertile there were no predictors for FR. BL predicted FR in women with mother's fracture in univariate and multivariate model (OR 2.6; 1.15-5.7, P = .021) but with sister's fracture this was observed only in multivariate model (OR 2.66; 1.09-6.7, P = .039). Accordingly, the risk factors for postmenopausal fractures, especially mother's fracture, may interact with BL.

Correlates and predictors of self-rated health and ambulatory status among elderly women - Cross-sectional and 10 years population-based cohort study. Maturitas 2009; 65:244-52. [PMID: 20018468 DOI: 10.1016/j.maturitas.2009.11.014] [Citation(s) in RCA: 14] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/08/2009] [Revised: 10/31/2009] [Accepted: 11/13/2009] [Indexed: 10/20/2022]
Abstract
AIM To investigate the correlates and predictors of self-rated health (SRH) and self-reported ambulatory status (AMB) among elderly women. SUBJECTS AND METHODS A random sample of 1620 postmenopausal women aged 53-66 years in 1994 was selected from Osteoporosis Risk Factor and Prevention (OSTPRE) - study cohort in Finland. SRH and AMB were assessed in baseline (1994) and after 10-year follow-up (2004). A prognostic model was developed to predict the probability of good 10-year SRH and AMB. RESULTS Full AMB was correlated with and predicted by good SRH (OR=4.3, p<0.001). Good quality of life (QoL) was both correlate and predictor of good 10-year SRH (OR=2.0, p<0.001) and full AMB (OR=2.6, p<0.001). Low BMI was associated with good SRH (OR=0.97, p<0.049) and full AMB (OR=0.92, p<0.001), good grip strength with good SRH (OR=2.7, p<0.001) and ability to squat down with full AMB (OR=1.7, p=0.002). Cardiovascular diseases, arthritis and back pain were common significant negative correlates (p<0.001) of baseline AMB and SRH out of variety of chronic diseases with significant association with either one. The significant (p<0.05) baseline predictors in final prognostic model for good 10-year SRH included baseline AMB and SRH, QoL, age, BMI, grip strength and psychiatric diseases (C-index=0.81) and for full 10-year AMB ability to squat, baseline AMB and SRH, QoL, BMI, hypertension and arthritis (C-index=0.81). These risk scores had better predictive power in comparison to that of baseline SRH and AMB alone (p<0.001 in univariate Z-score test). CONCLUSIONS Among elderly women AMB is strongly linked to SRH. SRH and AMB are affected mostly by musculoskeletal, cardiovascular and psychiatric diseases as well as body anthropometry, muscle strength and subjective QoL. The present study provides a novel algorithm for predicting probability of full AMB and good SRH in postmenopausal women.

Sister's fracture history may be associated with perimenopausal bone fragility and modifies the predictability of fracture risk. Osteoporos Int 2009; 20:557-65. [PMID: 18661087 DOI: 10.1007/s00198-008-0704-1] [Citation(s) in RCA: 8] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/25/2008] [Accepted: 06/23/2008] [Indexed: 11/28/2022]
Abstract
SUMMARY The present study investigated the effects of first degree relatives' fractures on fracture incidence after the menopause. Sister's, but not other relatives', wrist or hip fracture history was associated with increased risk of fragility fractures after the menopause. This suggests genetic predisposition to bone fragility among postmenopausal women. OBJECTIVE The aim of the present study was to investigate the association between first degree relatives' fractures and perimenopausal bone fragility. MATERIALS AND METHODS The study sample of 971 perimenopausal women was extracted from randomly selected Kuopio Osteoporosis Risk Factor and Prevention cohort and measured with dual X-ray absorptiometry in femoral neck (FN) in baseline (1989-1991), in 5 years (1994-97), and in 10 years (1999-2001). All low-trauma energy fractures during the 10-year follow-up were recorded based on self-reports and validated from medical records. First degree relatives' history of life-time hip and wrist fractures (exact classification or trauma energy not specified) was questioned by postal inquiries. RESULTS There was a significant correlation between fathers' vs. brothers' and mothers' vs. sisters' fractures (p < 0.01 in Pearson bivariate correlations). Sister's, but not mother's, father's, or brother's wrist and hip fractures were associated with significantly lowered 10-year fragility fracture-free survival rate (HR = 0.56, p = 0.006). Sisters' or other relatives' fractures were not associated with FN bone loss rate or bone mineral density (BMD) in the follow-up measurements (p = NS in ANCOVA). The predictive power of BMD for fragility fractures differed according to sisters' fracture history: Baseline FN T score predicted fracture-free survival only among women without sisters' fracture history (HR 0.62, p < 0.001 vs. women with sisters' fracture in Cox regression). CONCLUSIONS In conclusion, sisters' fracture history is associated with 10-year fracture-free survival in perimenopausal women but not with BMD or its changes. Predictability of fragility fracture risk with BMD may depend on sister's fracture history. This may indirectly suggest genetic predisposition to bone fragility independently of BMD.

Physical tests for patient selection for bone mineral density measurements in postmenopausal women. Bone 2009; 44:660-5. [PMID: 19138768 DOI: 10.1016/j.bone.2008.12.010] [Citation(s) in RCA: 33] [Impact Index Per Article: 2.2] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/16/2008] [Revised: 11/26/2008] [Accepted: 12/08/2008] [Indexed: 10/21/2022]
Abstract
INTRODUCTION There is a need for cost-effective clinical methods to select women for bone densitometry. The aim of the present study was to determine whether relatively simple and clinically applicable physical tests could be useful in prediction of bone density in postmenopausal women. METHODS A total of 606 women (age range 66-71 years) taking part in the population based OSTPRE Fracture Prevention Study were investigated. Spinal and femoral bone mineral density (BMD) was measured by Dual X-ray Absorptiometry (DXA). Physical tests included the standing-on-one-foot (SOOF), grip strength (GS), leg extension strength, ability to squat down, standing 10 s eyes closed, chair rising, regular walk for 10 m and tandem walk for 6 m. All linear regression models were adjusted for age, body mass index, years on hormone therapy, years since menopause, current smoking and use of oral glucocorticoids. RESULTS The SOOF was associated with lumbar spine BMD (r2=0.16, p=0.004) and the femoral regions (r2 values from 0.17 to 0.23 and p-values all<0.001). The GS was associated with lumbar spine BMD (r2=0.16, p=0.011) and the femoral regions (r2 values from 0.16 to 0.21 and p-values from <0.001 to 0.004). The ability to squat down on the floor was associated with the femoral regions (r2 values from 0.15 to 0.21 and p-values from 0.028 to 0.040). In addition, functional capacity was decreased in women with femoral neck osteoporosis (WHO classification) compared to women with normal or osteopenic BMD: SOOF -39% (p=0.001), GS -18% (p<0.001), leg extension strength -19% (p=0.007) and ability to squat down on the floor -40% (p=0.004). For osteoporosis prediction (ROC analysis) a threshold of a 22 kg in GS would yield a true-positive rate (sensitivity) of about 58% and a true-negative rate (specificity) of 86% (AUC 0.76). CONCLUSIONS We suggest that grip strength could be used in medical decision making to identify those women who would benefit from BMD measurements albeit alone it may not provide accurate enough tool for osteoporosis screening.

Grip strength may facilitate fracture prediction in perimenopausal women with normal BMD: a 15-year population-based study. Calcif Tissue Int 2008; 83:93-100. [PMID: 18641912 DOI: 10.1007/s00223-008-9155-0] [Citation(s) in RCA: 27] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/26/2008] [Accepted: 06/10/2008] [Indexed: 11/30/2022]
Abstract
The aim of the present study was to investigate the ability of grip strength measurements to predict fracture risk in perimenopausal women according to bone mineral density (BMD). A random sample of 971 perimenopausal women from the Kuopio Osteoporosis Risk Factor and Prevention study cohort was measured with dual-energy X-ray absorptiometry (DXA) at the femoral neck and grip strength with a pneumatic squeeze dynamometer in 5-year intervals from baseline (1989-1991). Fractures during the 15-year follow-up were recorded based on self-reports and validated from medical records. In the total sample and in osteopenic or osteoporotic women (T score < -1, n = 284) grip strength was not significantly associated with fracture-free survival rate (P = nonsignificant in Cox regression). In women with normal baseline BMD (N-BMD, T score > -1, n = 687) the lowest grip strength quartile had a significantly lower fracture-free survival rate in the Cox proportional hazard model (P = 0.005, hazard ratio [HR] = 2.0). In the multivariate Cox regression model, T score and grip strength were the only significant predictors of 15-year fracture-free survival in the N-BMD group and a risk index (RI) was formed according to HRs of these two variables. High RI (0-5 points) was associated with significantly lower 15-year fracture-free survival rate (P = 0.001, HR = 0.137) in the N-BMD group. In contrast, 5-year T score was no better a predictor of fractures in the baseline N-BMD group (P = 0.04, HR = 0.36). In conclusion, grip strength predicts 15-year fracture-free survival in perimenopausal women with N-BMD, while 5-year DXA does not seem to be any better a predictor of fracture risk. DXA measurements could be coupled with simple and cost-effective grip strength measurements. Controlling BMD in women with N-BMD could be abandoned.

Association between functional capacity tests and fractures: an eight-year prospective population-based cohort study. Osteoporos Int 2008; 19:1203-10. [PMID: 18236100 DOI: 10.1007/s00198-008-0561-y] [Citation(s) in RCA: 50] [Impact Index Per Article: 3.1] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/07/2007] [Accepted: 01/02/2008] [Indexed: 10/22/2022]
Abstract
UNLABELLED This study of postmenopausal women (n=2,928) with an eight-year follow-up revealed that impairment in functional status associated with the increased fracture risk. The standing-on-one-foot and grip strength tests and a question about self-assessed ability to move can be used to identify women with a high risk of suffering a fracture. INTRODUCTION Poor functional status has pointed to associate with injurious falls and consequent fractures. Our aim was to define association between functional capacity and fractures. METHODS This study was based on the Osteoporosis Risk Factor and Prevention Study (OSTPRE). A total of 2,928 postmenopausal women took part in the functional capacity and muscle strength tests. The duration of fracture follow-up varied from 6.43 to 9.86 (mean 8.37) years and the first fracture was the end-point event for the statistical analyses. All analyses were done with Cox-regression. RESULTS A total of 261 end-point fractures occurred. In multivariate analysis the inability to stand-on-one-foot for 10 seconds increased the risk of hip fracture (hazard ratio with 95% CI) 9.11-fold (1.98-42.00). Decreased grip strength associated with 1.05-fold (1.01-1.09) increased risk of hip fractures. Low leg extension strength associated with 1.02-fold (1.00-1.03) higher risk for all fractures. The self-assessed ability to walk less than 100 meters at baseline increased the risk of ankle 2.36-fold (1.10-5.08), hip 11.57-fold (2.73-49.15) and clinical vertebral fractures 3.85-fold (1.45-10.22). CONCLUSION According to these results the standing-on-one-foot less than 10 seconds, grip strength and a question about ability to walk less than 100 meters may help to predict postmenopausal fractures.
