Relationship between osteocalcin and glucose metabolism in postmenopausal women

BACKGROUND: Recently, osteocalcin was found to regulate blood glucose, insulin secretion, and fat deposition in mice. However, the relationship between osteocalcin levels and factors related to glucose metabolism in humans has not yet been investigated. We investigated the relationship between osteocalcin and glucose metabolism in postmenopausal women. METHODS: Three hundred thirty-nine postmenopausal women were recruited for this study. Glucose metabolism related substance and serum osteocalcin were assayed. RESULTS: There was a significant reduction in osteocalcin levels among type 2 diabetes mellitus patients compared with the normal glucose and impaired fasting glucose groups. Next, the subjects in the highest quartile for osteocalcin were observed to have significantly decreased fasting glucose and HbA1c levels compared with subjects in the lowest quartile. In addition, osteocalcin levels were inversely correlated with glucose, insulin, HbA1c, and insulin resistance. Moreover, multivariate analysis showed that serum osteocalcin was found to be an independent factor associated with glucose and HbA1c. CONCLUSIONS: There is a potential role of osteocalcin in regulating blood glucose levels in postmenopausal women. This finding indicates that in humans the skeleton may be involved in energy metabolism by functioning as part of the endocrine system.

Influence of obesity and sarcopenic obesity on plantar pressure of postmenopausal women

Background

Menopause is associated with a decrease in fat-free mass and an increase in fat mass. Sarcopenic obesity is more strongly associated with physical limitations than either obesity or sarcopenia and their effect in plantar pressure is not known. Consequently, the scope of the present study was to examine the effect of obesity and sarcopenic obesity on plantar pressure of postmenopausal women, during walking.

Methods

Body composition and biomechanics parameters of plantar pressure were assessed in 239 postmenopausal women.

Findings

Compared to non-obese and non-sarcopenic women, obese postmenopausal women have higher peak pressure in the metatarsal areas 1, 4, 5, midfoot and lateral heel and higher absolute impulses in all metatarsal and heel areas. On the other hand, sarcopenic obese postmenopausal women presented higher peak pressure and absolute impulses under all metatarsal areas, midfoot and heels. When the absolute values of maximal peak pressures and absolute impulses were normalised to body mass, pressure increases were only perceived for midfoot.

Interpretation

The pressure increase found in different foot areas of obese and particularly in sarcopenic obese could cause discomfort and pain in the foot. Sarcopenic obese postmenopausal women also present a higher loading during the stance phase comparing with non-sarcopenic non-obese, fact that might limit their basic daily activity tasks, such as walking.

Relationship between the estimates of desaturase activities and cardiometabolic phenotypes in Koreans

In the present study, we evaluated the relationships of estimated desaturase activities with cardiometabolic risk factors including abdominal obesity, atherogenic lipoprotein phenotype and inflammation in Koreans. Ninety-three healthy volunteers participated in this cross-sectional study. LDL particle size was determined using gradient gel electrophoresis and inflammatory markers including C-reactive protein, soluble intercellular adhesion molecule-1, and adiponectin were measured. Stearoyl–coA desaturase, delta-6 desaturase and delta-5 desaturase were estimated as precursor to fatty acid ratios. The results showed that stearoyl–coA desaturase was correlated with body mass index (r = 0.235, p<0.05), triglyceride (r = 0.261, p<0.001), and HDL-cholesterol (r = −0.226, p<0.05). Stearoyl–coA desaturase was associated with only triglyceride (r = 0.283, p<0.01). Delta-6 desaturase was correlated with body mass index (r = 0.236, p<0.05), waist circumference (r = 0.218, p<0.05), triglyceride (r = 0.399, p<0.001), C-reactive protein (r = 0.333, p<0.001), soluble intercellular adhesion molecule-1 (r = 0.229, p<0.05), HDL-cholesterol (r = −0.325, p<0.01), LDL particle size (r = −0.297, p<0.01) and adiponectin (r = −0.233, p<0.05). In contrast, delta-5 desaturase was correlated with body mass index (r = −0.324, p<0.01), waist circumference (r = −0.276, p<0.01), triglyceride (r = −0.329, p<0.01), C-reactive protein (r = −0.215, p<0.05), HDL-cholesterol (r = 0.262, p<0.05) and LDL particle size (r = 0.278, p<0.01). Stepwise multiple regression analysis revealed that delta-6 desaturase (p<0.01) together with waist circumference (p<0.001) were found to be independent factors for determining plasma levels of C-reactive protein (R² = 0.230). Estimated desaturase activities are closely associated with the features of cardiometabolic risk in Koreans.

Coagulation and inflammatory markers in Alzheimer's and vascular dementia

Alzheimer's disease is classified as a degenerative dementia while vascular dementia is known to be associated with atherothrombosis and classical vascular risk factors. However, over the last decade, there is increasing evidence of the role of haemostatic factors and inflammatory mechanisms in the pathogenesis of Alzheimer's disease. Serum markers of hypercoagulability and markers of inflammation could lead to thrombosis, accelerated atherogenesis and resulting dementia of both Alzheimer's and vascular dementia. In this case control study, we studied these serum markers of coagulation and inflammation in patients suffering from dementia.     

Biological variation in inflammatory and hemostatic markers

Summary.  Background:  Concentrations of inflammatory and hemostatic variables are influenced by biological variation, which is the natural within-subject variation over time. Objectives:  The aim of this study was to determine fibrinogen, C-reactive protein (CRP), platelet aggregation, thrombin generation and prothrombin time (PT): (i) the number of repeated measurements needed to obtain the true habitual concentration of an individual; (ii) the recommended analytical imprecision for diagnosis and monitoring; (iii) the recommended analytical bias; (iv) the contribution of analytical imprecision to test result variability; (v) the index of individuality; (vi) the reference change value; and (vii) the seasonal variation. Subjects and methods:  We collected 520 blood samples over a 1-year period from 40 healthy individuals, and determined the between-subject, within-subject and seasonal variation in fibrinogen, CRP, platelet aggregation, thrombin generation and PT. Results:  One or two repeated measurements were sufficient to establish the true habitual concentration, except for platelet aggregation and peak thrombin generation, where at least four and nine repeated measurements were needed, respectively. For diagnosis, the maximal recommended coefficient of analytical variation (CV) was 4%–27%, except for CRP (77.7%). For monitoring, these CVs were on average 3% lower. Recommended analytical bias varied between 1.7% and 33.2%. Finally, seasonal variation was observed in concentrations of fibrinogen and thrombin generation, which could explain approximately 11% of their total variation. Conclusion:  This study provides insights into the biological variability of selected inflammatory and hemostatic markers, which can be used for sample size calculations and to determine the analytical quality specifications for their respective assays.

Differential impact of conventional-dose and low-dose postmenopausal hormone therapy, tibolone and raloxifene on C-reactive protein and other inflammatory markers

Summary.  Background:  Postmenopausal hormone therapy (HT) is associated with an increased risk for arterial and venous thrombosis. Objectives:  To compare the impact of HT, tibolone, and raloxifene on C-reactive protein (CRP) and other inflammatory markers, and to investigate possible underlying mechanisms for changes in CRP and D-dimer. Methods:  Two hundred and two healthy women were randomly assigned to treatment for 12 weeks with either low-dose HT containing 1 mg of 17β-estradiol and 0.5 mg of norethisterone acetate (NETA) ( n  = 50), conventional-dose HT containing 2 mg of 17β-estradiol and 1 mg of NETA ( n  = 50), 2.5 mg of tibolone ( n  = 51), or 60 mg of raloxifene ( n  = 51). Results:  CRP increased in the conventional-dose HT and low-dose HT groups. These changes were significantly more pronounced in the conventional-dose HT group ( rmanova, P  = 0.02). Also, tibolone was associated with an increase in CRP, in contrast to raloxifene, which reduced CRP. Reductions in levels of Lp(a), intercellular adhesion molecule-1 (ICAM-1), P-selectin, E-selectin, monocyte chemotactic protein 1 (MCP-1) and interleukin-6 (IL-6) were observed in all treatment groups. The changes were most pronounced for the conventional-dose HT group, and least pronounced for the raloxifene group, whereas the changes in those allocated to tibolone and low-dose HT were intermediary. Increased levels of tumor necrosis factor (TNF)-α and von Willebrand factor (VWF) were seen in the raloxifene group. We observed positive associations between changes in IL-6, VWF, MCP-1, and CRP. Conclusions: The regimens had markedly different impacts on markers of inflammation. The average increase in CRP was not accompanied by increases in the average levels of IL-6, TNF-α or other markers, but women with large reductions in IL-6 had reduced increases in CRP.

Bone turnover markers and estradiol level in postmenopausal women.

It has been found recently that women with estradiol (E) levels < 5 pg/ml were more likely to suffer osteoporotic fractures. We evaluated the relationships between biomarkers of bone turnover and changes in hormone levels in early or late postmenopausal women without any replacement therapy. Follicle stimulating hormone (FSH), luteinizing hormones (LH), estradiol and serum resorption (crosslaps) and formation (osteocalcin) markers were assayed. Bone densities in the spine and femoral neck were also measured. Elevated FSH, LH and decreased estradiol in postmenopausal women were accompanied by higher osteocalcin (9.1-9.7 ng/ml) and crosslaps level (3305-3458 pmol/l) compared to premenopausal women (6.8 ng/ml and 2087 pmol/l). Bone density was lower in elderly women. A significant inverse correlation was found between estradiol and crosslaps level; FSH and LH were also correlated with bone markers. Estradiol levels < 9 pg/ml were associated with increased bone resorption, decreased hip bone density and higher frequency of osteopenia and osteoporosis. Over 57% of women with an estradiol < 9 pg/ml could be identified as having "a high turnover" compared with 30% with estradiol above 9 pg/ml. Our results indicate that changes in bone density may not be very clear but an increase in bone turnover is distinctly apparent in women with severe estradiol deficiency.
