Objective: The aim of this study was to evaluate the potential effect of the methanolic extract of plantGlycyrrhiza glabraroots on bone mineral density and femoral bone strength of ovariectomized rats.Methods: Thirty 10-month-old Wistar rats were randomly separated into three groups of ten, Control, Ovariectomy and Ovariectomy-plus-Glycyrrhiza in their drinking water. Total and proximal tibial bone mineral density was measured in all groups before ovariectomy (baseline) and after 3 and 6 months post ovariectomy. Three-point-bending of the femurs and uterine weight and histology were examined at the end of the study.Results: No significant difference was noted in bone density percentage change of total tibia from baseline to 3 months between Control and Ovariectomy-plus-Glycyrrhiza groups (+5.31% ± 4.75 and +3.30% ± 6.31 respectively,P = non significant), and of proximal tibia accordingly (+5.58% ± 6.92 and +2.61% ± 13.62,P = non significant) demonstrating a strong osteoprotective effect. There was notable difference in percentage change of total tibia from baseline to 6 months between groups Ovariectomy and Ovariectomy-plus-Glycyrrhiza (−13.03% ± 5.11 and −0.84% ± 7.63 respectively,P < 0.005), and of proximal tibia accordingly (−27.9% ± 3.69 and −0.81% ± 14.85 respectively,P < 0.001), confirming the protective effect ofGlycyrrhiza glabraextract in preserving bone density of the Ovariectomy-plus-Glycyrrhiza group. Three-point-bending did not reveal any statistically significant difference between Ovariectomy and Ovariectomy-plus-Glycyrrhiza groups. Uterine weights of the Ovariectomy-plus-Glycyrrhiza group ranged between the other two groups with no statistically significant difference to each.Conclusions:Glycyrrhiza glabraroot extract notably protected tibial bone mineral density loss in Ovariectomy-plus-Glycyrrhiza rats in comparison with ovariectomized rats, but did not improve biomechanical strength.

Background: The risk factors of metabolic syndrome (MetS) in menopausal women are potential causes of osteoporosis. However, there is no consensus on this. We aimed to determine the relationship between risk factors of MetS and bone mineral density (BMD) in menopausal Korean women. Methods: We enrolled 205 menopausal Korean women who visited a health promotion center in Seoul in 2015 and divided them into the following two groups according to the National Cholesterol Education Program-Adult Treatment Panel III (NCEP-ATP III) criteria with modified waist-circumference criteria: the non-MetS group (Group 1, n=90) and the MetS group (Group 2, n=115). Anthropometric parameters and clinical parameters, including blood pressure, blood lipid profile (cholesterol, triglycerides), and fasting blood sugar levels were recorded for all participants. BMD at the lumbar spine was determined using dual-energy X-ray absorptiometry (DEXA). The relationship between the risk factors of MetS and bone mineral density was analyzed by statistical methods. Results: There was no significant difference in risk factors of MetS between the groups. In correlation tests, waist circumference showed a significant association with body surface area (BSA) (r = -0.242, P < 0.001). Diastolic blood pressure was correlated with BSA (r = 0.186, P < 0.01) and bone mineral content (BMC) (r = 0.161, P < 0.05). However, multiple regression analysis showed no significant relationship between MetS risk factors and BMD. Conclusion: The risk factors of MetS did not affect BMD in menopausal Korean women. Follow-up studies with a larger study population are necessary size to allow the investigation of other research variables.

The Relationship

HIV-infected individuals are at risk for decreased bone mineral density (BMD). The known risk factors for bone loss do not fully explain the increased risk in this population. There is emerging evidence that leptin, a hormone secreted by adipocytes, plays an important role in bone metabolism. Several studies have assessed the relationship between leptin and bone density in healthy adults, but there are few such studies in HIV-infected individuals. Furthermore, HIV infected individuals on antiretroviral therapy are at increased risk for altered fat distribution, which may impact the relationship between leptin and BMD. In a cross-sectional analysis of data in 107 HIV-infected men, we determined whether serum leptin levels were associated with whole-body BMD and bone mineral content measured by dual-energy X-ray absorptiometry (DEXA), after adjusting for confounders including body fat distribution. We found an inverse association between leptin and bone density in those with peripheral lipoatrophy, defined objectively as <3 kg appendicular fat by DEXA, but no such relationship was seen in those with >3 kg appendicular fat. This result suggests that fat distribution may modify the relationship between leptin and bone density.

Purpose: To evaluate the effect of pulsed electro-magnetic therapy and exercise training on bone mineral density (BMD) in elderly women with osteoporosis. Material and Methods: A total of 30 elderly women with osteoporosis aged from 60 to 70 years old were randomly divided into two groups: A magnetic group consisting of 15 women who received pulsed electro-magnetic therapy at a frequency of 33 Hz and an intensity of 50 gauss for 50 min per session and an exercise group consisting of 15 women who practiced active exercises that included treadmill walking and selected exercises for hip and back muscles for 50 min per session. Both interventions were applied for three sessions/week for three months at a physical therapy clinic. Dual-energy X-ray absorptiometry was used to measure the BMD of the neck of the femur and the lumbar spine (L3-L5) before and after intervention. Results: Statistical analysis revealed that the BMD of the neck of the femur and the lumbar spine significantly increased in the two groups without a significant difference between them. Conclusion: Pulsed electro-magnetic therapy and exercises can increase BMD at the neck of the femur and the lumbar spine in elderly women. Physical therapists could apply pulsed electro-magnetic therapy or exercise training to increase BMD in elderly women.

Bone Mineral Measurements

Bone mineral density measurements have been criticized on the grounds that they are not a worth-while screening tool. In this paper we argue that bone mineral measurements can be an efficient diagnostic tool even if they are not of proven value for screening. There is complex relationship between the costs of a measurement, the intervention and the predictive value of the test all of which must be accounted for when assessing the value of a bone density measurement. For bone density measurements to be used for screening, a wider evaluation needs to be undertaken compared with that for their use as a diagnostic tool. We address some common objections, for example, that low compliance with screening would undermine efficiency, and show that these are not relevant. Evaluations of screening need to address issues that are likely to affect efficiency.

Background:Inflammatory bowel disease (IBD), including ulcerative colitis (UC) and Crohn’s disease (CD), is considered as a risk factor of low bone mineral density (BMD). In fact, the prevalence of osteoporosis ranges from 17% to 41% in IBD patients. The possible contributing factors may include malabsorption, glucocorticoid treatment and coexisting comorbiditiesObjectives:The purpose of our work was to determine the frequency and the determinants of osteoporosis in patients with IBD and to assess whether there is a difference in BMD status between UC and CD.Methods:This is a retrospective study, over a period of 5 years (from January 2014 to December 2018) and including patients followed for IBD who had a measurement of BMD by DEXA. Clinical, anthropometric and densitometric data (BMD at the femoral and vertebral site) were recorded. The WHO criteria for the definition of osteoporosis and osteopenia were applied.Results:One hundred and five patients were collected; among them 45 were men and 60 were women. The average age was 45.89 years old. The average body mass index (BMI) was 25.81 kg/m2 [16.44-44.15]. CD and UC were diagnosed in respectively 57.1% and 42.9%. A personal history of fragility fracture was noted in 4.8%. Hypothyroidism was associated in one case. Early menopause was recorded in 7.6%. 46.8% patients were treated with corticosteroids. The mean BMD at the vertebral site was 1.023 g/cm3 [0.569-1.489 g/cm3]. Mean BMD at the femoral site was 0.920g/cm3 [0.553-1.286g / cm3]. The mean T-score at the femoral site and the vertebral site were -1.04 SD and -1.27 SD, respectively. Osteoporosis was found in 25.7% and osteopenia in 37.1%. Osteoporosis among CD and UC patients was found in respectively 63% and 37%. The age of the osteoporotic patients was significantly higher compared to those who were not osteoporotic (52.23 vs 43.67 years, p = 0.01). We found a significantly higher percentage of osteoporosis among men compared to women (35.6% vs 18.3%, p=0.046). The BMI was significantly lower in the osteoporotic patients (23.87 vs 26.48 kg/m2, p=0.035) and we found a significant correlation between BMI and BMD at the femoral site (p=0.01). No increase in the frequency of osteoporosis was noted in patients treated with corticosteroids (27.9% vs 21.6%, p=0.479). Comparing the UC and CD patients, no difference was found in baseline characteristics, use of steroids or history of fracture. No statistically significant difference was found between UC and CD patients for osteoporosis(p=0.478), BMD at the femoral site (p=0.529) and at the vertebral site (p=0.568).Conclusion:Osteoporosis was found in 25.7% of IBD patients without any difference between CD and UC. This decline does not seem to be related to the treatment with corticosteroids but rather to the disease itself. Hence the interest of an early screening of this silent disease.Disclosure of Interests:None declared

The Relationship

Little is known about the effect of lumbar intervertebral disc herniation (LDH) on lumbar bone mineral density (BMD), and few previous studies have used quantitative computed tomography (QCT) to assess whether the staging of LDH correlates with lumbar vertebral trabecular volumetric bone mineral density (Trab.vBMD). To explore the relationship between lumbar Trab.vBMD and LDH, seven hundred and fifty-four healthy participants aged 20–60 years were enrolled in the study from an ongoing study on the degeneration of the spine and knee between June 2014 and 2017. QCT was used to measure L2–4 Trab.vBMD and lumbar spine magnetic resonance images (MRI) were performed to assess the incidence of disc herniation. After 9 exclusions, a total of 322 men and 423 women remained. The men and women were divided into younger (age 20–39 years) and older (age 40–60 years) groups and further into those without LDH, with a single LDH segment, and with ≥2 segments. Covariance analysis was used to adjust for the effects of age, BMI, waistline, and hipline on the relationship between Trab.vBMD and LDH. Forty-one younger men (25.0%) and 59 older men (37.3%) had at least one LDH segment. Amongst the women, the numbers were 46 (22.5%) and 80 (36.4%), respectively. Although there were differences in the characteristics data between men and women, the difference in Trab.vBMD between those without LDH and those with single and ≥2 segments was not statistically significant (p > 0.05). These results remained not statistically significant after further adjusting for covariates (p > 0.05). No associations between lumbar disc herniation and vertebral trabecular volumetric bone mineral density were observed in either men or women.

Abstract Background/Aims  Vitamin D deficiency is associated with more severe presentation of primary hyperparathyroidism (PTHP) with high parathyroid hormone (PTH) levels and reduced bone mineral density (BMD). We analyzed data to determine if vitamin D levels had any impact on PTH, serum calcium and BMD at diagnosis and 3 years, in patients being managed conservatively. Methods  Retrospective analysis of patients presenting with PHPT. Based on vitamin D level at diagnosis, patients were divided into two groups; vitamin D sufficient (≥ 50 nmol/L) and vitamin D insufficient (≤ 50 nmol/L). The two groups were compared for age, serum calcium and PTH levels at diagnosis and after mean follow up of 3 years. BMD at forearm and neck of femur (NOF) was only analyzed in the two groups at diagnosis, due to lack of 3 year’s data. Results  There were a total of 93 patients, 17 males, mean age 70; range 38-90. Mean vitamin D level was 73.39 nmol/L in sufficient group (n = 42) and 34.48 nmol/L in insufficient group (n = 40), (difference between means -38.91, 95% confidence interval -45.49 to -32.33, p &lt; 0.0001). There was no significant difference in age, serum calcium and PTH at the time of diagnosis. After three years, there was no significant difference in vitamin D levels between the two groups (mean vitamin D 72.17 nmol/L in sufficient group and 61.48 nmol/L in insufficient group). Despite rise in vitamin D level in insufficient group, no significant change was observed in this group in PTH and serum calcium levels. BMD was lower at both sites in vitamin D sufficient group and difference was statistically significant at NOF. Data were analyzed using unpaired t test and presented as mean ± SEM. Conclusion  50% of patients presenting with PHPT were vitamin D insufficient at diagnosis. Vitamin D was adequately replaced so that at 3 years there was no significant difference in vitamin D status in the two groups. Serum calcium and PTH were no different in the two groups at diagnosis and at three years, despite rise in vitamin D levels in the insufficient group. Interestingly, BMD was lower at forearm and neck of femur in those with sufficient vitamin D levels and the difference was statistically significant at neck of femur. Our data show that vitamin D insufficiency does not have any significant impact on PTH and calcium levels and that vitamin D replacement is safe in PHPT and does not impact serum calcium and PTH levels in the short term. Lower BMD in those with adequate vitamin D levels is difficult to explain and needs further research. Disclosure  M. Khalid: None. V. Deshani: None. K. Jadoon: None.

ABSTRACT Objective: The objective of this study is to investigate the effect of passive smoking during pregnancy and associated with swimming on bone area growth, bone mineral density (BMD), and bone mineral content (BMC). Methods: The offspring was grouped by control matrices (G1) and passive smokers (G2). The offspring was regrouped in eight subgroups, with exposure to smoking (2x/day) and physical exercise (1 session/day), respecting the group of matrices in: sedentary control (G1CS and G2CS), swimming control (G1CN and G2CN), sedentary passive smoker (G1FS and G2FS), and passive smoker swimmer (G1FN and G2FN). The area, BMD and BMC were measured by the tibia and femur and analyzed by densitometer. The results were analyzed by One-Way ANOVA test with Tukey post-test, with a significance level of 5%. Results: In the tibia BMC study, a better rate was observed in G2CN group when compared to G1CS, G1CN and G1FN (p ≤ 0.023). When assessing BMD in the femur, a higher density ratio was observed in G1FS group when compared to G2CS, G2CN, G2FS and G2FN (p<0.008). In the tibia study, the animals of the G1FS group had higher rates when compared to G2CS and G2FN groups (p≤0.007). Conclusions: The model of male offspring exposed to passive smoking during fetal development showed a strong decrease in the analyzed parameters. Level of Evidence I, Randomized High Quality Clinical Trial With or Without Statistically Significant Difference, But Narrow Confidence Intervals.
