Abstract: Summary: The relationship between self-reported falls and fracture risk was estimated in an international meta-analysis of individual-level data from 46 prospective cohorts. Previous falls were associated with an increased fracture risk in women and men and should be considered as an additional risk factor in the FRAX® algorithm. Introduction: Previous falls are a well-documented risk factor for subsequent fracture but have not yet been incorporated into the FRAX algorithm. The aim of this study was to evaluate, in an international meta-analysis, the association between previous falls and subsequent fracture risk and its relation to sex, age, duration of follow-up, and bone mineral density (BMD). Methods: The resource comprised 906,359 women and men (66.9% female) from 46 prospective cohorts. Previous falls were uniformly defined as any fall occurring during the previous year in 43 cohorts; the remaining three cohorts had a different question construct. The association between previous falls and fracture risk (any clinical fracture, osteoporotic fracture, major osteoporotic fracture, and hip fracture) was examined using an extension of the Poisson regression model in each cohort and each sex, followed by random-effects meta-analyses of the weighted beta coefficients. Results: Falls in the past year were reported in 21.4% of individuals. During a follow-up of 9,102,207 person-years, 87,352 fractures occurred of which 19,509 were hip fractures. A previous fall was associated with a significantly increased risk of any clinical fracture both in women (hazard ratio (HR) 1.42, 95% confidence interval (CI) 1.33–1.51) and men (HR 1.53, 95% CI 1.41–1.67). The HRs were of similar magnitude for osteoporotic, major osteoporotic fracture, and hip fracture. Sex significantly modified the association between previous fall and fracture risk, with predictive values being higher in men than in women (e.g., for major osteoporotic fracture, HR 1.53 (95% CI 1.27–1.84) in men vs. HR 1.32

2. Role of the microbiome in regulating bone metabolism and susceptibility to osteoporosis

Author: Cronin, O., Lanham-New, S.A., Corfe, B.M., Gregson, C.L., Darling, A.L., Ahmadi, K.R., Gibson, P.S., Tobias, J.H., Ward, K.A., Traka, M.H., Rossi, M., Williams, C., Harvey, N.C., Cooper, C., Whelan, K., Uitterlinden, A.G., O’Toole, P.W., Ohlsson, C., Compston, J.E., and Ralston, S.H.
Abstract: The human microbiota functions at the interface between diet, medication-use, lifestyle, host immune development and health. It is therefore closely aligned with many of the recognised modifiable factors that influence bone mass accrual in the young, and bone maintenance and skeletal decline in older populations. While understanding of the relationship between micro-organisms and bone health is still in its infancy, two decades of broader microbiome research and discovery supports a role of the human gut microbiome in the regulation of bone metabolism and pathogenesis of osteoporosis as well as its prevention and treatment. Pre-clinical research has demonstrated biological interactions between the microbiome and bone metabolism. Furthermore, observational studies and randomized clinical trials have indicated that therapeutic manipulation of the microbiota by oral administration of probiotics may influence bone turnover and prevent bone loss in humans. In this paper, we summarize the content, discussion and conclusions of a workshop held by the Osteoporosis and Bone Research Academy of the Royal Osteoporosis Society in October, 2020. We provide a detailed review of the literature examining the relationship between the microbiota and bone health in animal models and in humans, as well as formulating the agenda for key research priorities required to advance this field. We also underscore the potential pitfalls in this research field that should be avoided and provide methodological recommendations to facilitate bridging the gap from promising concept to a potential cause and intervention target for osteoporosis.

Abstract: Nuclear receptor subfamily 5 group A member 1 (NR5A1) encodes steroidogenic factor 1 (SF1), a key regulatory factor that determines gonadal development and coordinates endocrine functions. Here, we have established a stem cell-based model of human gonadal development and applied it to evaluate the effects of NR5A1 during the transition from bipotential gonad to testicular cells. We combined directed differentiation of human induced pluripotent stem cells (46,XY) with activation of endogenous NR5A1 expression by conditionally-inducible CRISPR activation. The resulting male gonadal-like cells expressed several Sertoli cell transcripts, secreted anti-Müllerian hormone and responded to follicle-stimulating hormone by producing sex steroid intermediates. These characteristics were not induced without NR5A1 activation. A total of 2691 differentially expressed genetic elements, including both coding and non-coding RNAs, were detected immediately following activation of NR5A1 expression. Of those, we identified novel gonad-related putative NR5A1 targets, such as SCARA5, which we validated also by immunocytochemistry. In addition, NR5A1 activation was associated with dynamic expression of multiple gonad- and infertility-related differentially expressed genes. In conclusion, by combining targeted differentiation and endogenous activation of NR5A1 we have for the first time, been able to examine in detail the effects of NR5A1 in early human gonadal cells. The model and results obtained provide a useful resource for future investigations exploring the causative reasons for gonadal dysgenesis and infertility in humans.

Abstract: Increased blood lipid levels are heritable risk factors of cardiovascular disease with varied prevalence worldwide owing to different dietary patterns and medication use1. Despite advances in prevention and treatment, in particular through reducing low-density lipoprotein cholesterol levels2, heart disease remains the leading cause of death worldwide3. Genome-wideassociation studies (GWAS) of blood lipid levels have led to important biological and clinical insights, as well as new drug targets, for cardiovascular disease. However, most previous GWAS4‐23 have been conducted in European ancestry populations and may have missed genetic variants that contribute to lipid-level variation in other ancestry groups. These include differences in allele frequencies, effect sizes and linkage-disequilibrium patterns24. Here we conduct a multi-ancestry, genome-wide genetic discovery meta-analysis of lipid levels in approximately 1.65 million individuals, including 350,000 of non-European ancestries. We quantify the gain in studying non-European ancestries and provide evidence to support the expansion of recruitment of additional ancestries, even with relatively small sample sizes. We find that increasing diversity rather than studying additional individuals of European ancestry results in substantial improvements in fine-mapping functional variants and portability of polygenic prediction (evaluated in approximately 295,000 individuals from 7 ancestry groupings). Modest gains in the number of discovered loci and ancestry-specific variants were also achieved. As GWAS expand emphasis beyond the identification of genes and fundamental biology towards the use of genetic variants for preventive and precision medicine25, we anticipate that increased diversity of participants will lead to more accurate and equitable26 application of polygenic scores in clinical practice.

Abstract: With increasing age of the population, countries across the globe are facing a substantial increase in osteoporotic fractures. Genetic association signals for fractures have been reported at the RSPO3 locus, but the causal gene and the underlying mechanism are unknown. Here we show that the fracture reducing allele at the RSPO3 locus associate with increased RSPO3 expression both at the mRNA and protein levels, increased trabecular bone mineral density and reduced risk mainly of distal forearm fractures in humans. We also demonstrate that RSPO3 is expressed in osteoprogenitor cells and osteoblasts and that osteoblast-derived RSPO3 is the principal source of RSPO3 in bone and an important regulator of vertebral trabecular bone mass and bone strength in adult mice. Mechanistic studies revealed that RSPO3 in a cell-autonomous manner increases osteoblast proliferation and differentiation. In conclusion, RSPO3 regulates vertebral trabecular bone mass and bone strength in mice and fracture risk in humans.

Abstract: Obesity has previously been thought to protect bone since high body weight and body mass index are associated with high bone mass. However, some more recent studies suggest that increased adiposity negatively impacts bone mass. Here, we aimed to test whether acute loss of adipose tissue, via adipocyte apoptosis, alters bone mass in age-related obese mice. Adipocyte apoptosis was induced in obese male FAT-ATTAC mice through AP20187 dimerizer-mediated activation of caspase 8 selectively in adipocytes. In a short-term experiment, dimerizer was administered to 5.5 month-old mice that were terminated 2 weeks later. At termination, the total fat mass weighed 58% less in dimerizer-treated mice compared with vehicle-treated controls, but bone mass did not differ. To allow for the detection of long-term effects, we used 9-month-old mice that were terminated six weeks after dimerizer administration. In this experiment, the total fat mass weighed less (− 68%) in the dimerizer-treated mice than in the controls, yet neither bone mass nor biomechanical properties differed between groups. Our findings show that adipose tissue loss, despite the reduced mechanical loading, does not affect bone in age-related obese mice. Future studies are needed to test whether adipose tissue loss is beneficial during more severe obesity.

Abstract: The stress hormone cortisol modulates fuel metabolism, cardiovascular homoeostasis, mood, inflammation and cognition. The CORtisol NETwork (CORNET) consortium previously identified a single locus associated with morning plasma cortisol. Identifying additional genetic variants that explain more of the variance in cortisol could provide new insights into cortisol biology and provide statistical power to test the causative role of cortisol in common diseases. The CORNET consortium extended its genome-wide association meta-analysis for morning plasma cortisol from 12,597 to 25,314 subjects and from similar to 2.2 M to similar to 7 M SNPs, in 17 population-based cohorts of European ancestries. We confirmed the genetic association with SERPINA6/SERPINA1. This locus contains genes encoding corticosteroid binding globulin (CBG) and alpha 1-antitrypsin. Expression quantitative trait loci (eQTL) analyses undertaken in the STARNET cohort of 600 individuals showed that specific genetic variants within the SERPINA6/SERPINA1 locus influence expression of SERPINA6 rather than SERPINA1 in the liver. Moreover, trans-eQTL analysis demonstrated effects on adipose tissue gene expression, suggesting that variations in CBG levels have an effect on delivery of cortisol to peripheral tissues. Two-sample Mendelian randomisation analyses provided evidence that each genetically-determined standard deviation (SD) increase in morning plasma cortisol was associated with increased odds of chronic ischaemic heart disease (0.32, 95% CI 0.06–0.59) and myocardial infarction (0.21, 95% CI 0.00–0.43) in UK Biobank and similarly in CARDIoGRAMplusC4D. These findings reveal a causative pathway for CBG in determining cortisol action in peripheral tissues and thereby contributing to the aetiology of cardiovascular disease.

Subjects: *THYROTROPIN, *CONFIDENCE intervals, *HYPERTHYROIDISM, *REGRESSION analysis, *RISK assessment, *OSTEOPOROSIS, *VERTEBRAL fractures, *PROPORTIONAL hazards models, *BONE fractures, *DISEASE risk factors, *DISEASE complications, *OLD age
Abstract: Summary: In elderly men included in MrOS-Sweden, subclinical hyperthyroidism (SHyper) was markedly associated with increased risk of vertebral fractures. Introduction: Overt hyperthyroidism is associated with increased risk of fractures. However, only a few studies have investigated whether SHyper is associated with fracture risk in elderly men. We therefore investigated if SHyper was a risk factor for fractures in Swedish men. Methods: We followed (median 9.8 years) elderly men (n = 1856; mean age 75, range 69–81 years) participating in the Gothenburg and Malmö subcohorts of the prospective, population-based MrOS-Sweden study. The statistical analyses included Cox proportional hazards regression. SHyper was defined as serum thyroid-stimulating hormone (TSH) < 0.45 mIU/L (n = 38). Results: SHyper was associated with increased risk of all fractures [n = 456; hazard ratio (HR) adjusted for age, study center, and levothyroxine treatment = 1.99, 95% confidence interval (CI): 1.20–3.32], major osteoporotic fractures (MOF, n = 338; HR 2.44, 95% CI: 1.42–4.21), and vertebral fractures (n = 176; HR 3.79, 95% CI: 2.02–7.11). These associations remained after full adjustment for covariates including total hip bone mineral density and in subanalyses including only men with serum free thyroxine ≤ the upper normal limit. However, after exclusion of men receiving levothyroxine treatment, the associations with all fractures and MOF lost significance. Conclusions: In elderly Swedish men, there was a strong association between SHyper and increased risk of vertebral fractures, whereas the associations with all incident fractures and MOF need to be confirmed in further studies.

Abstract: Vitamin D is a steroid hormone precursor that is associated with a range of human traits and diseases. Previous GWAS of serum 25-hydroxyvitamin D concentrations have identified four genome-wide significant loci (GC, NADSYN1/DHCR7, CYP2R1, CYP24A1). In this study, we expand the previous SUNLIGHT Consortium GWAS discovery sample size from 16,125 to 79,366 (all European descent). This larger GWAS yields two additional loci harboring genome-wide significant variants (P = 4.7×10−9 at rs8018720 in SEC23A, and P = 1.9×10−14 at rs10745742 in AMDHD1). The overall estimate of heritability of 25-hydroxyvitamin D serum concentrations attributable to GWAS common SNPs is 7.5%, with statistically significant loci explaining 38% of this total. Further investigation identifies signal enrichment in immune and hematopoietic tissues, and clustering with autoimmune diseases in cell-type-specific analysis. Larger studies are required to identify additional common SNPs, and to explore the role of rare or structural variants and gene–gene interactions in the heritability of circulating 25-hydroxyvitamin D levels.

10. High platelet count is associated with low bone mineral density: The MrOS Sweden cohort.

Author: Kristjansdottir, H.L., Mellström, D., Johansson, P., Karlsson, M., Vandenput, L., Lorentzon, M., Herlitz, H., Ohlsson, C., Lerner, U.H., and Lewerin, C.
Subjects: BIOMARKERS, HEMOGLOBINS, PLATELET count, HYPOTHESIS, LEUKOCYTE count, DESCRIPTIVE statistics, BONE density, BONE marrow
Abstract: Summary: In elderly ambulatory men, high platelet and high neutrophil counts are related to low bone mineral density (BMD), after adjustment for relevant covariates. Low hemoglobin (hgb) is even associated with low BMD, but this relationship seems to be dependent on estradiol and osteocalcin. Purpose: Blood and bone cells exist in close proximity to each other in the bone marrow. Accumulating evidence, from both preclinical and clinical studies, indicates that these cell types are interconnected. Our hypothesis was that BMD measurements are associated with blood count variables and bone remodeling markers. Methods: We analyzed blood count variables, bone remodeling markers, and BMD, in subjects from the MrOS cohort from Gothenburg, Sweden. Men with at least one blood count variable (hgb, white blood cell count, or platelet count) analyzed were included in the current analysis (n = 1005), median age 75.3 years (range 69–81 years). Results: Our results show that high platelet counts were related to low BMD at all sites (total hip BMD; r = − 0.11, P = 0.003). No statistically significant association was seen between platelet counts and bone remodeling markers. Neutrophil counts were negatively associated with total body BMD (r = − 0.09, P = 0.006) and total hip BMD (r = − 0.08, P = 0.010), and positively related to serum ALP (r = 0.15, P < 0.001). Hgb was positively related to total hip BMD (r = 0.16, P < 0.001), and negatively to serum osteocalcin (r = − 0.13, P < 0.001). The association between platelet and neutrophil counts and total hip BMD was statistically significant after adjustments for other covariates, but the association between hgb and total hip BMD was dependent on estradiol and osteocalcin. Conclusions: Our observations support the hypothesis of an interplay between blood and bone components. [ABSTRACT FROM AUTHOR]

Subjects: BEREAVEMENT, CONFIDENCE intervals, DEATH, BONE fractures, FRAIL elderly, HIP joint injuries, LONGITUDINAL method, MARRIAGE, RISK assessment, SPOUSES, WIDOWHOOD, RETROSPECTIVE studies, DISEASE risk factors
Abstract: Summary: Death of a spouse is associated with poorer physical and mental health. We followed all married individuals, born from 1902 to 1942, during the period from 1987 to 2002, and found that widows and widowers had higher risk for hip fracture, compared with still married women and men. Introduction: Spousal bereavement can lead to poorer physical and mental health. We aimed to determine whether married women and men had an elevated risk of hip fracture after death of a spouse. Methods: In a retrospective cohort study, we followed all Swedish married individuals aged 60 to 100 years (n = 1,783,035), from 1987 to 2002. Data are presented as mean with 95% confidence interval (CI). Results: During the follow-up period, 21,305 hip fractures among widows and 6538 hip fractures among widowers were noted. The hazard ratio (HR) for hip fracture in widows compared with married women was 1.34 (95% CI 1.31 to 1.37) and for widowers compared with married men 1.32 (95% CI 1.29 to 1.35). The HR for hip fracture in the first 6 months after death of a spouse was in widows compared with married women 1.62 (95% CI 1.53 to 1.71) and in widowers compared with married men 1.84 (95% CI 1.68 to 2.03). The elevated risk was especially prominent in young widowers in the age range 60–69 years. During the first 6 months they showed a HR of 2.76 (95% CI 1.66 to 4.58) for a hip fractvure compared with age matched married men. Widows aged 60–69 years showed a HR of 1.59 (95% CI 1.26 to 1.99) compared with age matched married women. Conclusion: Our observation of a higher hip fracture risk in both genders in connection with the death of a spouse indicates a possible effect of bereavement on frailty. [ABSTRACT FROM AUTHOR]

Abstract: Few genome-wide association studies (GWAS) account for environmental exposures, like smoking, potentially impacting the overall trait variance when investigating the genetic contribution to obesity-related traits. Here, we use GWAS data from 51,080 current smokers and 190,178 nonsmokers (87% European descent) to identify loci influencing BMI and central adiposity, measured as waist circumference and waist-to-hip ratio both adjusted for BMI. We identify 23 novel genetic loci, and 9 loci with convincing evidence of gene-smoking interaction (GxSMK) on obesity-related traits. We show consistent direction of effect for all identified loci and significance for 18 novel and for 5 interaction loci in an independent study sample. These loci highlight novel biological functions, including response to oxidative stress, addictive behaviour, and regulatory functions emphasizing the importance of accounting for environment in genetic analyses. Our results suggest that tobacco smoking may alter the genetic susceptibility to overall adiposity and body fat distribution.

We examined whether genetic variants affect body shape as a composite phenotype that is represented by a combination of anthropometric traits. We developed an approach that calculates averaged PCs (AvPCs) representing body shape derived from six anthropometric traits (body mass index, height, weight, waist and hip circumference, waist-to-hip ratio). The first four AvPCs explain >99% of the variability, are heritable, and associate with cardiometabolic outcomes. We performed genome-wide association analyses for each body shape composite phenotype across 65 studies and meta-analysed summary statistics. We identify six novel loci: LEMD2 and CD47 for AvPC1, RPS6KA5/C14orf159 and GANAB for AvPC3, and ARL15 and ANP32 for AvPC4. Our findings highlight the value of using multiple traits to define complex phenotypes for discovery, which are not captured by single-trait analyses, and may shed light onto new pathways.

Abstract: Summary: We aimed to study the risk of hip fracture and risk of hip arthroplasty among farmers in Sweden. Our results indicate that farming, representing an occupation with high physical activity, in men is associated with a lower risk of hip fracture but an increased risk of hip arthroplasty.Introduction: The risks of hip fracture and hip arthroplasty are influenced by factors including socioeconomic status, education, urbanization, latitude of residence, and physical activity. Farming is an occupation encompassing rural living and high level of physical activity. Therefore, we aimed to study the risk of hip fracture and risk of hip arthroplasty among farmers in Sweden.Methods: We studied the risk of hip fracture, and hip arthroplasty due to primary osteoarthritis, in all men and women aged 35 years or more in Sweden between 1987 and 2002. Documented occupations were available in 3.5 million individuals, of whom 97,136 were farmers. The effects of age, sex, income, education, location of residence, and occupation on risk of hip fracture or hip arthroplasty were examined using a modification of Poisson regression.Results: A total of 4027 farmers and 93,109 individuals with other occupations sustained a hip fracture, while 5349 farmers and 63,473 others underwent a hip arthroplasty. Risk of hip fracture was higher with greater age, lower income, lower education, higher latitude, and urban area for all men and women. Compared to all other occupations, male farmers had a 20% lower age-adjusted risk of hip fracture (hazard ratio (HR) 0.80, 95%CI 0.77-0.84), an effect that was not seen in female farmers (HR 0.96, 95% CI 0.91-1.01). Both male and female farmers had a higher age-adjusted risk for hip arthroplasty.Conclusions: Our results indicate that farming, representing an occupation with high physical activity, in men is associated with a lower risk of hip fracture but an increased risk of hip arthroplasty.

Abstract: Summary: Spouses tend to share habits and therefore have an increased risk of same diseases. We followed all married couples in Sweden, born 1902 to 1942, in hospital records from 1987 to 2002, and found that individuals whose spouse had a hip fracture had an increased risk of hip fracture. Introduction: The purpose of this study was to determine whether spouses of hip fracture patients have an elevated risk of hip fracture. Methods: We performed a retrospective cohort study of all couples married for at least 5 years in Sweden and born between 1902 and 1942 ( n = 904,451) and all patients registered with a hip fracture ( n = 218,285) in the National Inpatients Register in Sweden from 1987 to 2002. Results: During the period 1987 to 2002 hip fractures occurred among spouses in 4212 married couples. The hazard ratio (HR) for hip fracture in a married woman following hip fracture in the husband was 1.11 (95 % confidence interval 1.07 to 1.16) compared to a woman whose husband did not have hip fracture. The corresponding HR for a married man was 1.20 (1.15 to 1.26) compared to a man whose wife did not have hip fracture. The risk was significantly elevated over the age range 60 to 90 years. The increased risk for hip fracture among spouses remained after adjustments for income, education, geographical latitude and urbanisation. In a common model with spouses and their siblings, the HR for spousal effect were 1.63 (1.01 to 2.64) and for sibling effect 2.18 (1.55 to 3.06) compared to married with spouse and sibling respectively without hip fracture. Conclusion: The novel finding of an increased risk for hip fracture among spouses provides evidence indicating that there is a homogamy effect due to common social and lifestyle factors but could also be due to assortative mating.

Subjects: CONFIDENCE intervals, ACCIDENTAL falls, FEMUR neck, BONE fractures, PATIENT aftercare, LONGITUDINAL method, MEN, OSTEOPOROSIS, POISSON distribution, PROBABILITY theory, BONE density, DESCRIPTIVE statistics
Abstract: Summary: Falls and fractures share several common risk factors. Although past falls is not included as an input variable in the FRAX calculator, we demonstrate that FRAX probability predicts risk of incident falls in the MrOs Sweden cohort. Introduction: Although not included in the FRAX® algorithm, it is possible that increased falls risk is partly dependent on other risk factors that are incorporated into FRAX. The aim of the present study was to determine whether fracture probability generated by FRAX might also predict risk of incident falls and the extent that a falls history would add value to FRAX. Methods: We studied the relationship between FRAX probabilities and risk of falls in 1836 elderly men recruited to the MrOS study, a population-based prospective cohort of men from Sweden. Baseline data included falls history, clinical risk factors, bone mineral density (BMD) at femoral neck, and calculated FRAX probabilities. Incident falls were captured during an average of 1.8 years of follow-up. An extension of Poisson regression was used to investigate the relationship between FRAX, other risk variables, and the time-to-event hazard function of falls. All associations were adjusted for age and time since baseline. Results: At enrolment, 15.5 % of the men had fallen during the preceding 12 months (past falls) and 39 % experienced one or more falls during follow-up (incident falls). The risk of incident falls increased with increasing FRAX probabilities at baseline (hazard ratio (HR) per standard deviation (SD), 1.16; 95 % confidence interval (95%CI), 1.06 to 1.26). The association between incident falls and FRAX probability remained after adjustment for past falls (HR per SD, 1.12; 95%CI, 1.03 to 1.22). High compared with low baseline FRAX score (>15 vs <15 % probability of major osteoporotic fracture) was strongly predictive of increased falls risk (HR, 1.64; 95%CI, 1.36 to 1.97) and remained stable with time. Whereas past falls were a significant predictor of incident falls (HR, 2.75; 95%CI, 2.32 to 3.25), even after adjustment for FRAX, the hazard ratio decreased markedly with increasing follow-up time. Conclusions: Although falls are not included as an input variable, FRAX captures a component of risk for future falls and outperforms falls history with an extended follow-up time.

Abstract: Summary: Serum adiponectin is a risk factor for fracture. The predictive value attenuates with time in elderly men so that its use for the risk assessment in the long term is questionable. The study underlines the importance of testing the long-term stability of potential risk factors. Introduction: High serum adiponectin is associated with an increased risk of fracture in elderly men. The aim of the present study was to determine the impact of adiponectin on the probability of fracture as a function of time. Methods: The probability of osteoporotic fracture was computed in 989 elderly men from the MrOS study in Sweden. Baseline data included clinical risk factors for fracture, femoral neck BMD and serum adiponectin. Men were followed for up to 7.4 years with a mean follow up of 5.3 years (range 0.0-7.4 years). Poisson regression was used to model the hazard function for osteoporotic fracture and death to determine the 10 year probability of fracture. Results: During follow up, 124 men sustained one or more osteoporotic fracture. There was a significant interaction between adiponectin and time since baseline ( p = 0.026) such that the longer time since baseline, the lower the gradient of fracture risk. When using this interaction in the calculation of 10-year probability of fracture, the probabilities of osteoporotic fracture varied little over the range of adiponectin values. Conclusion: Serum adiponectin is a risk factor for fracture. Nevertheless, the predictive value attenuates with time so that its use for the risk assessment in the long term is questionable. This study underlines the importance of testing the long-term stability of potential risk factors that might be used in fracture risk assessment. [ABSTRACT FROM AUTHOR]

Abstract: Summary: In a population-based study on cobalamin status and incident fractures in elderly men ( n = 790) with an average follow-up of 5.9 years, we found that low levels of metabolically active and total cobalamins predict incident fractures, independently of body mass index (BMI), bone mineral density (BMD), plasma total homocysteine (tHcy), and cystatin C. Introduction: Cobalamin deficiency in elderlies may affect bone metabolism. This study aims to determine whether serum cobalamins or holotranscobalamin (holoTC; the metabolic active cobalamin) predict incident fractures in old men. Methods: Men participating in the Gothenburg part of the population-based Osteoporotic Fractures in Men (MrOS) Sweden cohort and without ongoing vitamin B medication were included in the present study ( n = 790; age range, 70-81 years). Results: During an average follow-up of 5.9 years, 110 men sustained X-ray-verified fractures including 45 men with clinical vertebral fractures. The risk of fracture (adjusted for age, smoking, BMI, BMD, falls, prevalent fracture, tHcy, cystatin C, 25-OH-vitamin D, intake of calcium, and physical activity (fully adjusted)), increased per each standard deviation decrease in cobalamins (hazard ratio (HR), 1.38; 95 % confidence intervals (CI), 1.11-1.72) and holoTC (HR, 1.26; 95 % CI, 1.03-1.54), respectively. Men in the lowest quartile of cobalamins and holoTC (fully adjusted) had an increased risk of all fracture (cobalamins, HR = 1.67 (95 % CI, 1.06-2.62); holoTC, HR = 1.74 (95 % CI, 1.12-2.69)) compared with quartiles 2-4. No associations between folate or tHcy and incident fractures were seen. Conclusions: We present novel data showing that low levels of holoTC and cobalamins predicting incident fracture in elderly men. This association remained after adjustment for BMI, BMD, tHcy, and cystatin C. However, any causal relationship between low cobalamin status and fractures should be explored in a prospective treatment study. [ABSTRACT FROM AUTHOR]

19. The role of estrogen receptor α in the regulation of bone and growth plate cartilage.

Author: Börjesson, A., Lagerquist, M., Windahl, S., and Ohlsson, C.
Subjects: ESTROGEN receptors, BONE growth, THROMBOEMBOLISM, BONE remodeling, CELLULAR signal transduction, GROWTH plate
Abstract: Estrogens are important endocrine regulators of skeletal growth and maintenance in both females and males. Studies have demonstrated that the estrogen receptor (ER)-α is the main mediator of these estrogenic effects in bone. Therefore, estrogen signaling via ERα is a target both for affecting longitudinal bone growth and bone remodeling. However, treatment with estradiol (E2) leads to an increased risk of side effects such as venous thromboembolism and breast cancer. Thus, an improved understanding of the signaling pathways of ERα will be essential in order to find better bone specific treatments with minimal adverse effects for different estrogen-related bone disorders. This review summarizes the recent data regarding the intracellular signaling mechanisms, in vivo, mediated by the ERα activation functions (AFs), AF-1 and AF-2, and the effect on bone, growth plate and other estrogen responsive tissues. In addition, we review the recent cell-specific ERα-deleted mouse models lacking ERα specifically in neuronal cells or growth plate cartilage. The newly characterized signaling pathways of estrogen, described in this review, provide a better understanding of the ERα signaling pathways, which may facilitate the design of new, bone-specific treatment strategies with minimal adverse effects.

Abstract: Summary: In this population-based study of 24-year-old men, we have investigated the association between sport-specific exercise loading and different bone parameters. We reveal that the association between exercise loading and bone parameters is sport-specific, indicating that nonspecific resistance exercise does not impact bone density, geometry, or microstructure in young men. Introduction: In this cross-sectional study, the association between nonspecific resistive exercise and areal and volumetric bone density, bone geometry, or bone microstructure was investigated in young adult men. Methods: A total of 184 male athletes, 24.0 ± 0.6 years of age (mean ± SD), representing nonspecific resistive exercise and soccer (proportion of recreational athletes, 93.4 and 7.7 %, respectively), and 177 nonathletic age-matched controls were measured with dual-energy X-ray absorptiometry. Radius and tibia were measured by peripheral quantitative computed tomography (pQCT) at the diaphysis and by three-dimensional pQCT at the metaphysis. Results: Men in the nonspecific resistive exercise group had higher grip strength(9.1 % or 0.4 SD) and higher lean mass(5.6 % or 0.5 SD) than those in the nonathletic group( p < 0.01 and p < 0.001, respectively). However, men who participated in nonspecific resistive exercise did not have higher bone density or a more favorable bone microstructure or geometry than their nonathletic referents. In contrast, men playing soccer had higher areal bone mineral density (aBMD) at the femoral neck (19.5 % or 1.2 SD) and lumbar spine (12.6 % or 1.0 SD), as well as larger cortical cross-sectional area (16.4 % or 1.1 SD) and higher trabecular bone volume fraction (14.5 % or 0.9 SD), as a result of increased trabecular number (8.7 % or 0.6 SD) and thickness (5.7 % or 0.4 SD) at the tibia than men in the nonathletic group( p < 0.001). Conclusions: Weight-bearing exercise with impacts from varying directions (playing soccer) is associated with aBMD and volumetric BMD, cortical bone geometry, as well as trabecular microstructure of weight-bearing bone. Nonspecific recreational resistance exercise does not appear to be a strong determinant of bone density, geometry, or microstructure in young adult men. [ABSTRACT FROM AUTHOR]

Abstract: Summary: This study examines the association between sex steroids, bone mineral density (BMD), and incident fractures in 1,489 community-living Chinese men aged 65 and over. Chinese men with low serum estradiol levels display elevated bone loss and increased risk of fractures similar to findings in Caucasians. Introduction: This study examines the association between serum total testosterone (TT), free testosterone (free T), estradiol (E), bioavailable estradiol (bioE), sex hormone binding globulin (SHBG), BMD, and incident fractures. Methods: This is a cohort study with 4-year follow-up in the community in Hong Kong SAR, China. One thousand four hundred eighty-nine community-living Chinese men aged 65 and over participated. Sex steroid levels and BMD were measured at baseline; BMD was repeated after 4 years of follow-up, and fracture incidence from ascertainment from hospital databases was determined over 4 years of follow-up. Results: The strongest age-adjusted positive association with total hip and femoral neck BMD was with bioE, followed by E. Greater bone loss occurred in the lowest quartile of E and bioE. The lowest quartile of free T and bioE and the two highest quartile of SHBG were associated with the highest percentage of participants with incident fractures. Those in the lowest quartile of E and bioE had approximately a 50% increased risk of incident fractures compared with the other three quartiles. This relationship remains significant for nonvertebral incident fractures (hip, radius, pelvis, and humerus) for E only, but not bioE. Compared with the group with the three highest quartiles of TT and E, the group with the lowest quartile of both had approximately twice the risk of nonvertebral osteoporosis-related incident fractures. Conclusion: Chinese men with low serum estradiol levels display elevated bone loss and increased risk of fractures similar to findings in Caucasians. [ABSTRACT FROM AUTHOR]

Abstract: Summary: In elderly man, low serum 25-hydroxyvitamin D (25(OH)D) was associated with a substantial excess risk of death compared to 25(OH)D values greater than 50-70 nmol/l, but the association attenuated with time. Introduction: The aim of the present study was to determine whether poor vitamin D status was associated with an increase in the risk of death in elderly men. Methods: We studied the relationship between serum 25(OH)D and the risk of death in 2,878 elderly men drawn from the population and recruited to the MrOS study in Sweden. Baseline data included general health and lifestyle measures and serum 25(OH)D measured by competitive RIA. Men were followed for up to 8.2 years (average 6.0 years). Results: Mortality adjusted for comorbidities decreased by 5% for each SD increase in 25(OH)D overall (gradient of risk 1.05; 95% confidence interval 0.96-1.14). The predictive value of 25(OH)D for death was greatest below a threshold value of 50-70 nmol/l, was greatest at approximately 3 years after baseline and thereafter decreased with time. Conclusions: Low serum 25(OH)D is associated with a substantial excess risk of death compared to 25(OH)D values greater than 50-70 nmol/l, but the association attenuates with time. These findings, if causally related, have important implications for intervention in elderly men. [ABSTRACT FROM AUTHOR]

Abstract: Summary: Advancing maternal age has been related to increased risk of fetal death and morbidity, as well as higher fracture risk during childhood, in the offspring. In the present study, we demonstrate that advancing maternal age is independently associated with reduced bone mass in the young adult male offspring. Introduction: In Sweden the maternal age in both primi- and multipara mothers has steadily increased during the last three decades. It has been previously reported that advancing maternal age increases the risk of fetal death, but also of morbidity in the offspring, such as chromosome abnormalities, leukemia, diabetes mellitus type 1, and schizophrenia. Whether or not maternal age influences peak bone mass has not been reported. The aim of the present study was to investigate whether a high maternal age was associated with lower peak bone mass, as measured using DXA in a large cohort of male offspring [the Gothenburg Osteoporosis and Obesity Determinants study (GOOD)]. Methods: Through the Swedish multi-generation register, we identified the mothers of 1,009 GOOD study subjects. From the Swedish medical birth register detailed information about the medical circumstances at the time of child birth were obtained, including maternal and offspring anthropometrics (birth height and weight), maternal age, and smoking habits, parity and length of pregnancy. Results: Maternal age was inversely correlated to areal BMD (aBMD) at the total body ( r =−0.07, p = 0.03) and the lumbar spine ( r =−0.09, p < 0.01). Using a linear regression model (with covariates including current physical activity, smoking, calcium intake, weight, present height and birth height, total body lean and fat mass in the offspring, and length of pregnancy), we found that maternal age negatively independently predicted lumbar spine aBMD ( β =−0.08, p < 0.01) in the male offspring. Conclusions: In conclusion, our results suggest that advancing maternal age could negatively affect bone mass in young adult men. [ABSTRACT FROM AUTHOR]

Subjects: BLOOD pressure, CROSS-sectional method, VITAMIN D, PARATHYROID hormone
Abstract: Vitamin D status, parathyroid hormone (PTH) level and their associations with blood pressure in Chinese population are unknown. This study examined these associations in older Chinese men. Blood pressure, serum 25-hydroxyvitamin D (25OHD) and PTH was measured in 939 community-dwelling Chinese men aged 65 years and older. Linear regression analyses were performed with adjustments for age, body mass index, education, season of measurement, medication use, self-reported history of stroke and Parkinson's disease, and other lifestyle factors. In either crude or adjusted models, serum 25OHD was not associated with blood pressure, whereas increasing PTH levels was associated with higher blood pressure. Men in the highest quartile of serum PTH level had a mean difference of 3.4 mm Hg and 2.8 mm Hg higher in as systolic blood pressure (SBP) and diastolic blood pressure (DBP), respectively, than men in the lowest quartile of serum PTH level (Ptrend=0.019 for SBP and <0.001 for DBP). In conclusion, the findings support an association between serum PTH and blood pressure, but not for serum 25OHD in older Chinese men whose vitamin D status is optimal. The lack of association between serum 25OHD and blood pressure may possibly because of the relatively high serum 25OHD levels of the study sample. [ABSTRACT FROM AUTHOR]

Abstract: Summary: We studied the nature of the relationship between bone mineral density (BMD) and the risk of death among elderly men. BMD was associated with mortality risk and was independent of adjustments for other co-morbidities. A piecewise linear function described the relationship more accurately than assuming the same gradient of risk over the whole range of BMD ( p = 0.020). Low BMD was associated with a substantial excess risk of death, whilst a higher than average BMD had little impact on mortality. Introduction: Previous studies have demonstrated an association between low BMD and an increased risk of death among men and women. The aim of the present study was to examine the pattern of the risk in men and its relation to co-morbidities. Methods: We studied the nature of the relationship between BMD and death among 3,014 elderly men drawn from the population and recruited to the MrOS study in Sweden. Baseline data included general health questionnaires, life style questionnaires and BMD measured using DXA. Men were followed for up to 6.5 years (average 4.5 years). Poisson regression was used to investigate the relationship between BMD, co-morbidities and the hazard function of death. Results: During follow-up, 382 men died (all-cause mortality). Low BMD at all measured skeletal sites was associated with increased mortality. In multivariate analyses, the relationship between BMD and mortality was non-linear, and a piecewise linear function described the relationship more accurately than assuming the same gradient of risk over the whole range of BMD ( p = 0.020). Conclusions: Low BMD is associated with a substantial excess risk of death compared to an average BMD, whereas a higher than average BMD has a more modest effect on mortality. These findings, if confirmed elsewhere, have implications for the constructing of probability-based fracture risk assessment tools. [ABSTRACT FROM AUTHOR]

26. Treatment with fall-risk-increasing and fracture-preventing drugs before and after a hip fracture: an observational study.

Author: Sjöberg C, Bladh L, Klintberg L, Mellström D, Ohlsson C, and Wallerstedt SM
Abstract: Background: Hip fracture is a common diagnosis in the older population, with often serious consequences. Drug treatment may be of significance for both falls and fractures. Objective: To investigate drug treatment in older hip fracture patients, focusing on use of fall-risk-increasing and fracture-preventing drugs before and after the fracture. Methods: This was an observational study conducted in Sahlgrenska University Hospital, Gothenburg, Sweden. The participants were 100 consecutive hip fracture patients aged ≥65 years with a median age of 86 (range 66-97) years. Seventy-three patients were female, and 87 patients had at least one strong risk factor for a fracture. Four patients died during the hospital stay, and a further 18 died within 6 months after discharge. Treatment with fall-risk-increasing and fracture-preventing drugs at admission to hospital, at discharge and 6 months after the hip fracture was measured. Results: The numbers of patients treated with fall-risk-increasing drugs were 93 (93%), 96 (100%) and 73(94%) at admission, discharge and 6-month follow-up, respectively. The median (range) number of such drugs was 3 (0-9), 4(1-10) and 3(0-10), respectively. A total of 17(17%), 32(33%) and 29(37%) patients were treated with fracture-preventing drugs, predominantly calcium plus vitamin D, at admission, discharge and 6-month follow-up, respectively. Five patients (5%) used bisphosphonates or selective estrogen receptor modulators at admission. No additional patients had these drugs prescribed during the hospital stay. At 6-month follow-up, four more patients were treated with bisphosphonates. Conclusions: Treatment with fall-risk-increasing drugs was extensive among older hip fracture patients both before and after the fracture. The proportion of patients with fracture-preventing drugs was low at admission and increased slightly during the follow-up period. Hence, drug treatment in older hip fracture patients can be improved regarding both fall-risk-increasing drugs and fracture-preventing drugs. [ABSTRACT FROM AUTHOR]

Studies of knockout mice show that endogenous interleukin (IL)-6 can suppress mature-onset obesity.Objective:To systematically investigate associations of single nucleotide polymorphisms (SNPs) near the IL-6 (IL6) and IL-6 receptor (IL6R) genes with body fat mass, in support for our hypothesis that variants of these genes can be associated with obesity.Design and Study Subjects:The Gothenburg Osteoporosis and Obesity Determinants (GOOD) study is a population-based cross-sectional study of 18- to 20-year-old men (n=1049), from the Gothenburg area (Sweden). Major findings were confirmed in two additional cohorts consisting of elderly men from the Osteoporotic Fractures in Men (MrOS) Sweden (n=2851) and MrOS US (n=5611) multicenter population-based studies.Main Outcome:The genotype distributions and their association with fat mass in different compartments, measured with dual-energy X-ray absorptiometry.Results:Out of 18 evaluated tag SNPs near the IL6 and IL6R genes, a recently identified SNP rs10242595 G/A (minor allele frequency=29%) 3′ of the IL6 gene was negatively associated with the primary outcome total body fat mass (effect size −0.11 standard deviation (s.d.) units per A allele, P=0.02). This negative association with fat mass was also confirmed in the combined MrOS Sweden and MrOS US cohorts (effect size −0.05 s.d. units per A allele, P=0.002). When all three cohorts were combined (n=8927, Caucasian subjects), rs10242595*A showed a negative association with total body fat mass (effect size −0.05 s.d. units per A allele, P<0.0002). Furthermore, the rs10242595*A was associated with low body mass index (effect size −0.03, P<0.001) and smaller regional fat masses. None of the other SNPs investigated in the GOOD study were reproducibly associated with body fat.Conclusions:The IL6 gene polymorphism rs10242595*A is associated with decreased fat mass in three combined cohorts of 8927 Caucasian men.

28. Relation between fibroblast growth factor-23, body weight and bone mineral density in elderly men.

Author: Marsell, R., Mirza, M. A. I., Mallmin, H., Karlsson, M., Mellström, D., Orwoll, E., Ohlsson, C., Jonsson, K. B., Ljunggren, Ö., and Larsson, T. E.
Subjects: BODY weight, BONE density, BONE densitometry, FIBROBLAST growth factors, BONE growth, HEALTH of older men, COHORT analysis
Abstract: We evaluated the relation between serum FGF23 and bone mineral density (BMD) in a community-based cohort of elderly men. There was a weak correlation between FGF23 and BMD, which was primarily dependent on body weight. FGF23 is a hormonal factor produced in bone and regulates serum levels of phosphate (Pi) and vitamin D. FGF23 over-expression is associated with skeletal abnormalities, including rickets/osteomalacia. The relation between FGF23 and Bone Mineral Density (BMD) in the community remains unexplored. We employed a large, population-based cohort of 3014 Swedish men aged 69–80 years, without known renal disease. BMD was measured with dual X-ray absorptiometry (DXA) in the hip and lumbar spine. Serum intact FGF23 was analyzed with a two-site monoclonal ELISA. There was a weak but significant correlation between FGF23 and BMD in femoral neck ( r = 0.04, p < 0.05), femoral trochanter ( r = 0.05, p = 0.004), total hip ( r = 0.06, p = 0.0015) and lumbar spine ( r = 0.07, p = 0.0004). The correlations remained significant when adjusting for biochemical covariates (Pi, calcium, PTH, 25(OH)D and renal function). However, the association became insignificant in all regions when adjusting for established confounding variables including age, height, weight and smoking. Further analysis confirmed a significant correlation between FGF23 and body weight ( r = 0.13, p < 0.0001). The weak correlation between FGF23 and BMD in elderly male subjects is mainly due to an association between FGF23 and body weight. Therefore, FGF23 may not play a significant role in the hormonal regulation of BMD. [ABSTRACT FROM AUTHOR]

Subjects: BENIGN prostatic hyperplasia, INSULIN, MULTIVARIATE analysis, SERUM, PROSTATE, DISEASE risk factors
Abstract: The aetiology of benign prostatic hyperplasia (BPH) remains unclear. The objective of the present study was to test the insulin, oestradiol and metabolic syndrome hypotheses as promoters of BPH. The design was a risk factor analysis of BPH in which the total prostate gland volume was related to endocrine and anthropometric factors. The participants studied were 184 representative men, aged 72–76 years, residing in Göteborg, Sweden. Using a multivariate analysis, BPH as measured by the total prostate gland volume correlated statistically significantly with fasting serum insulin (β=0.200, P=0.028), free oestradiol (β=0.233, P=0.008) and lean body mass (β=0.257, P=0.034). Insulin and free oestradiol appear to be independent risk factors for BPH, confirming both the insulin and the oestradiol hypotheses. Our findings also seem to confirm the metabolic syndrome hypothesis. The metabolic syndrome and its major endocrine aberration, hyperinsulinaemia, are possible primary events in BPH.Prostate Cancer and Prostatic Diseases (2009) 12, 160–165; doi:10.1038/pcan.2008.50; published online 30 September 2008 [ABSTRACT FROM AUTHOR]

Abstract: Context:Immune functions seem to have connections to variations in body fat mass. Studies of knockout mice indicate that endogenous interleukin (IL)-1 can suppress mature-onset obesity.Objective:To systematically investigate our hypotheses that single-nucleotide polymorphisms (SNPs) and/or haplotypes variants in the IL-1 gene system are associated with fat mass.Subjects:The Gothenburg osteoporosis and obesity determinants (GOOD) study is a population-based cross-sectional study of 18–20 year-old men (n=1068), from Gothenburg, Sweden. Major findings were confirmed in elderly men (n=3014) from the Swedish part of the osteoporotic fractures in men (MrOS) multicenter population-based study.Main Outcome Measure:The genotype distributions and their association with body fat mass in different compartments, measured with dual-energy X-ray absorptiometry (DXA).Results:Out of 15 investigated SNPs in the IL-1 receptor antagonist (IL1RN) gene, a recently identified 3′ untranslated region C>T (rs4252041, minor allele frequency=4%) SNP was associated with the primary outcome total fat mass (P=0.003) and regional fat masses, but not with lean body mass or serum IL-1 receptor 1 (IL1RN) levels. This SNP was also associated with body fat when correcting the earlier reported IL1RN+2018 T>C (rs419598) SNP (in linkage disequilibrium with a well-studied variable number tandem repeat of 86 bp). The association between rs4252041 SNP and body fat was confirmed in the older MrOS population (P=0.03). The rs4252041 SNP was part of three haplotypes consisting of five adjacent SNPs that were identified by a sliding window approach. These haplotypes had a highly significant global association with total body fat (P<0.001). None of the other investigated members of the IL-1 gene family displayed any SNPs that have not been described previously to be significantly associated with body fat.Conclusions:The IL1RN gene, shown to enhance obesity by suppressing IL-1 effects in experimental animals, have no previously described gene polymorphisms and haplotypes that are associated with fat, but not lean mass in two populations of men.International Journal of Obesity (2009) 33, 525–533; doi:10.1038/ijo.2009.47; published online 17 March 2009 [ABSTRACT FROM AUTHOR]

31. Competitive physical activity early in life is associated with bone mineral density in elderly Swedish men.

Author: Nilsson, M., Ohlsson, C., Eriksson, A. L., Frändin, K., Karlsson, M., Ljunggren, Ö., Mellström, D., and Lorentzon, M.
Subjects: *PHYSICAL fitness, *YOUNG men, *OLDER men, *HUMAN life cycle, *HEALTH, *ATHLETICS, *NURSING care facilities
Abstract: In this population-based study of 75-year-old men ( n = 498), we investigated the association between physical activity (PA) early in life and present bone mineral density (BMD). We demonstrate that a high frequency of competitive sports early in life is associated with BMD at several bone sites, indicating that increases in BMD following PA are preserved longer than previously believed. Physical activity (PA) increases bone mineral density (BMD) during growth. It is unclear if the positive effects remain at old age. In this study, we aimed to determine if PA early in life was associated with BMD in elderly men. In this population-based study, 498 men, 75.2 ± 3.3 (mean±SD) years old, were included. BMD was assessed using DXA. Data concerning lifetime PA, including both competitive (CS) and recreational sports (RS), and occupational physical load (OPL), were collected at interview. Subjects in the highest frequency group of CS in the early period (10–35 years), had higher BMD at the total body (4.2%, p < 0.01), total hip (7.0%, p < 0.01), trochanter (8.7%, p < 0.01), and lumbar spine (7.9%, p < 0.01), than subjects not involved in CS. A stepwise linear regression model showed that frequency of CS in the early period independently positively predicted present BMD at the total body (β = 0.12, p < 0.01), total hip (β = 0.11, p < 0.01), trochanter (β = 0.12, p < 0.01), and lumbar spine (β = 0.11, p = 0.01). We demonstrate that PA in CS early in life is associated with BMD in 75-year-old Swedish men, indicating that increases in BMD following PA are preserved longer than previously believed.

Abstract: Genetic variation in the androgen metabolizing enzymes is important to identify and feature as they may influence the risk of prostate cancer and help clarify the etiology of the disease. Human 17β-hydroxysteroid dehydrogenase type 5 (AKR1C3) is highly expressed in the prostate gland and plays a major role in the formation and metabolism of androgens. We identified five novel polymorphisms in the AKR1C3 gene. One of those an A>G substitution in exon 2 that confers a Glu77Gly change occurred in 4.8% in Caucasians but was completely absent in Orientals. Interestingly, the testosterone level in serum was significantly lower in subjects with the Gly77 allele. A promoter A>G polymorphism was associated with significantly altered promoter activity in reporter constructs, but was not associated with any change in testosterone levels. In conclusion, the Glu77Gly polymorphism is associated with lower testosterone levels in serum.The Pharmacogenomics Journal (2007) 7, 282–289; doi:10.1038/sj.tpj.6500419; published online 19 September 2006 [ABSTRACT FROM AUTHOR]

Subjects: GENETIC polymorphisms, POPULATION genetics, ADRENERGIC receptors, HYPERTENSION, BLOOD circulation disorders
Abstract: The Arg16Gly and the Gln27Glu polymorphisms in the gene for the β2-adrenergic receptor (β2AR) have been linked to an increased risk for cardiovascular disease. The aim of the present study was to evaluate the significance of these haplotypes for development of myocardial infarction (MI) as well as other cardiovascular phenotypes. In a prospective study cohort (CAPPP), 522 hypertensive patients (174 MI and 348 matched controls) were analysed for the Arg16Gly and the Gln27Glu polymorphisms by dynamic allele-specific hybridisation. The haplotype could successfully be determined in 516 patients. Haplotype was not significantly associated with MI. Systolic blood pressure (SBP) was higher in patients with Arg16Gly+Gln27Gln and lower in patients with Arg16Gly+Gln27Glu as compared with the other haplotypes. Haplotype was not associated with body mass index, diastolic blood pressure, cholesterol, LDL, HDL triglycerides or a diagnosis of diabetes mellitus. The present study found no evidence that haplotype for the two most common polymorphisms in the β2AR are associated with development of MI in a Swedish hypertensive population, but haplotype may be associated with SBP.Journal of Human Hypertension (2005) 19, 705–708. doi:10.1038/sj.jhh.1001897; published online 2 June 2005 [ABSTRACT FROM AUTHOR]

Abstract: Osteoporosis is a well-known side effect of long-term treatment with glucocorticoids. The hepatocyte growth factor (HGF) receptor is expressed by human osteoclasts and osteoblasts, and mouse osteoblasts also express HGF, indicating that HGF may regulate bone metabolism. Because HGF could be a candidate factor in the local paracrine signaling between osteoblasts and osteoclasts in bone, we decided to study whether human osteoblasts secrete HGF and whether glucocorticoids regulate the expression of HGF. HGF was easily detectable in the culture medium from human osteoblast-like cells (hOB). The HGF protein released into the culture medium was increased with increasing confluency. Hydrocortisone decreased the amount of HGF released into the culture medium from hOB in a dose-dependent manner with a maximal effect at 10(-6) M. Time-course studies revealed that hydrocortisone decreased the amount of HGF released into the culture medium significantly after 16 hours of stimulation (65 +/- 2% of control culture). This effect of hydrocortisone was maximal after 24 hours of stimulation (52 +/- 8% of control culture). In conclusion, HGF is produced by primary cultured hOB cells. Furthermore, the amount of HGF released into the culture medium is decreased by glucocorticoids. The biological significance of this finding remains to be demonstrated. [ABSTRACT FROM AUTHOR]

38. The relative importance of endocrine versus autocrine/paracrine insulin-like growth factor-I in the regulation of body growth.

Subjects: *REGULATION of growth, *SOMATOTROPIN, *SOMATOMEDIN, *MICE, *SCIENTIFIC experimentation, *PHYSIOLOGY
Abstract: Body growth is regulated by growth hormone (GH) and insulin-like growth factor-I (IGF-I). The classical somatomedin hypothesis of this regulation is that most IGF-I in the blood originates in the liver and that body growth is controlled by the concentration of IGF-I in the blood. We have recently abolished IGF-I production in the livers of mice by using the Cre/loxP recombination system. These mice displayed a more than 75% reduction in serum IGF-I associated with increased serum levels of GH. In contrast, they demonstrated a normal postnatal growth, indicating that extrahepatic, autocrine/paracrine-acting IGF-I is the main determinant of postnatal growth. Thus, the ”classical” somatomedin hypothesis needs revision. We propose the ”dual somatomedin hypothesis” according to which: (1) autocrine/paracrine IGF-I is the main determinant of postnatal body growth and (2) liver-derived, endocrine-acting, IGF-I exerts negative feedback on GH secretion and possibly also exerts other effects on carbohydrate and lipid metabolism.
