The effect of Cornus mas extract consumption on bone biomarkers and inflammation in postmenopausal women: A randomized clinical trial. Phytother Res 2021; 35:4425-4432. [PMID: 33969554 DOI: 10.1002/ptr.7143] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/31/2020] [Revised: 04/13/2021] [Accepted: 04/13/2021] [Indexed: 11/09/2022]
Abstract
The drastic decrease in estrogen levels in menopausal women can elevate bone resorption and osteoporosis. Cornus mas extract (C. mas extract) is a potential candidate for treating menopausal-related bone complications because of its phytoestrogen and anti-inflammatory contents. It was an interventional double-blind placebo-controlled randomized study. Eighty-four women aged 45-60 years old were randomly allocated to either the extract group receiving 3 capsules of 300 mg C. mas extract or the placebo group receiving 3 capsules of 300 mg of starch powder per day for 8 weeks. Then, venous blood was used to measure bone-specific alkaline phosphatase (BAP), osteocalcin (OC), C-terminal telopeptide (TC) as well as serum levels of PTH and hsCRP. Our results indicated the decrease in alkaline phosphatase, PTH, and as an inflammation biomarker, hsCRP, between two groups at the end of the study. No statistically significant difference was observed in telopeptide C, osteocalcin, and calcium between the placebo and extract groups after 8 weeks of intervention. In conclusion, the results indicate that the C. mas extract supplement of 900 mg/day may decrease levels of BAP, PTH, and hsCRP. However, this intervention had no beneficial effect on OC and TC in healthy postmenopausal women.

Reference values for bone metabolism in a Japanese cohort survey randomly sampled from a basic elderly resident registry. Sci Rep 2021; 11:7822. [PMID: 33837266 PMCID: PMC8035137 DOI: 10.1038/s41598-021-87393-7] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2020] [Accepted: 03/19/2021] [Indexed: 11/09/2022] Open
Abstract
The aim of this study was to provide definitive reference values for bone mineral density (BMD) and bone turnover markers in the general elderly population. Registered citizens of 50 to 89 years old were targeted for this survey. After random sampling from the resident registry of Obuse town, we established eight groups based on age (50 s, 60 s, 70 s, and 80 s) and gender. A total of 411 people were enrolled. We used a dual-energy x-ray absorptiometry device to measure and evaluate BMD. The bone formation marker bone alkaline phosphatase (BAP) was measured as a bone turnover marker. Bone quality marker pentosidine, and bone resorption markers including urinary total deoxypyridinoline (DPD), tartrate-resistant acid phosphatase 5b (TRACP-5b), 25-hydroxyvitamin D (25[OH]D), and whole parathyroid hormone (PTH) were also measured as bone turnover markers. Sixty-three people (15.3%) were diagnosed as osteoporosis. BMD decreased with age in the femoral neck and total hip. On the other hand, there was no characteristic change with age in the lumber spine. As for bone markers, pentosidine and DPD increased with aging, although 25(OH)D, whole PTH, and BAP showed no characteristic associations with gender and aging. In terms of the relationship between low BMD and bone markers, there was a significant independent association between low BMD and TRACP-5b in females. In conclusions, hip BMD decreased with aging in men and women. However, there was no characteristic decline with aging in the lumbar spine. All bone markers showed no significant independent characteristics associated with age or gender in a multivariate analysis model, except for a significant association between low BMD and TRACP-5b in females. TRACP-5b was a potentially useful marker for the detection of low BMD.

Abstract
Background: Metabolic syndrome is defined as a state of metabolic dysregulation characterized by insulin resistance, a predisposition to Type 2 diabetes mellitus and atherosclerotic vascular disease. The changing hormonal milieu with altered estrogen and testosterone ratio is the cause of metabolic syndrome at menopausal transition. Aims and Objectives: This study was designed to determine the incidence of metabolic syndrome and its various components in premenopausal and postmenopausal women from Punjab. Materials and Methods: This study was conducted on 200 females in the age group of 45–60 years attending outpatient department over a period of 2 years in the Department of Obstetrics and Gynaecology, Bebe Nanki Mother and Child Care Centre, Government Medical College, Amritsar. A detailed history and physical examination were done and recorded on a pro forma. Biochemical assessment comprising fasting blood glucose, triglycerides, and cholesterol was done. Metabolic syndrome was assessed as per the modified NCEP ATP III criteria. Results: Twenty-nine percent women were found to have newly onset metabolic syndrome, the incidence in premenopausal group was 16%, and in postmenopausal group was 42%. Among the components, the incidence of hypertension (58%) was the highest followed by waist circumference (42%). Maximum correlation of metabolic syndrome was found with high-density lipoprotein (odds ratio - 7.250) followed by waist circumference (odds ratio - 7.111). Conclusion: The incidence of metabolic syndrome was found to be higher in postmenopausal women than in premenopausal women. Currently, the need of the hour is lifestyle modification to reduce the emergence of metabolic syndrome and cardiovascular diseases.

Abstract
OBJECTIVE Bone turnover markers (BTMs) reflect the metabolic activity of bone tissue and can be used to monitor osteoporosis therapy. To adequately interpret BTMs, method-specific reference intervals are needed. We aimed to determine reference intervals for serum concentrations of intact amino-terminal propeptide of type I procollagen (PINP), bone-specific alkaline phosphatase (BAP) and carboxy-terminal telopeptide of type I collagen (CTX). MATERIAL AND METHODS We established a healthy reference population of 1107 men as well as 382 pre- and 450 postmenopausal women, who participated in the first follow-up of the Study of Health in Pomerania. Serum PINP, BAP and CTX concentrations were measured on the IDS-iSYS Automated System (Immunodiagnostic Systems, Frankfurt am Main, Germany). The reference interval was defined as the central 95% range. We determined age-specific reference intervals for PINP, BAP, and CTX for men by quantile regression. Reference intervals for women were age-independent. RESULTS Reference intervals for men for PINP and CTX decreased with age (25-29year-old men: PINP 31.1-95.9ng/mL, CTX 0.12-0.83ng/mL; 75-79year-old men: PINP 15.7-68.1ng/mL, CTX 0.05-0.58ng/mL). The reference interval for men for BAP did not significantly change with age (25-29year-old men: 7.4-27.7ng/mL; 75-79year-old men: 7.6-24.4ng/mL). The reference intervals for 30-54year-old premenopausal women were: PINP 19.3-76.3ng/mL, BAP 6.0-22.7ng/mL, and CTX 0.05-0.67ng/mL. The reference intervals for 50-79year-old postmenopausal women were: PINP 18.2-102.3ng/mL, BAP 8.1-31.6ng/mL, and CTX 0.09-1.05ng/mL. CONCLUSION An intensively characterized, large reference population free of bone-related diseases allowed us to determine robust reference intervals for serum concentrations of PINP, BAP and CTX. Our normative data may aid to interpret bone turnover in adult men and pre- and postmenopausal women.

Abstract
OBJECTIVE To determine the relationship between sociodemographic, reproductive and lifestyle factors and the severity of menopausal symptoms among Saudi women attending a university hospital in Riyadh city. METHODS A cross-sectional survey was carried out during 2010 in Riyadh city. Women aged > 40 years attending or accompanying their relatives in outpatient clinics in King Khalid University Hospital were invited to participate in the study. The English version of the Menopause Rating Scale (MRS) was used to assess the severity of menopausal symptoms after translation and validation on a sample of 30 women. RESULTS A total of 490 women were included. Severe urogenital symptoms were more common among housewives compared to working women (odds ratio (OR) 2.27, 95% confidence interval (CI) 1.12-4.68) and women living in apartments or small houses compared to women living in villas (OR 1.70, 95% CI 1.90-2.64). Nulliparous women had more severe somatic symptoms compared to those who had been pregnant (OR 2.83, 95% CI 1.10-7.69). Women who exercised regularly were less likely to experience severe somatic and urogenital symptoms (OR 0.57, 95% CI 0.37-0.86; OR 0.65, 95% CI 0.44-0.98, respectively). Obese women experienced more severe psychosomatic symptoms compared to those of normal body mass index (OR 2.01, 95% CI 0.96-4.93). CONCLUSION Women who are housewives, living in apartments, not exercising regularly and obese are more likely to suffer from severe symptoms of menopause.

Abstract
This study is carried out to determine the prevalence of metabolic syndrome (MS) in 148 women between 36 to 65 years using the International Diabetes Federation criteria in the North-Eastern part of India. The prevalence of MS and all its individual components were found to be significantly higher among postmenopausal as compared to premenopausal and perimenopausal women. Various components of MS except waist circumference shows a significant increase and homeostasis model assessment index for insulin resistance also showed significant differences between the three groups. All the MS diagnostic markers (except serum high density lipoprotein) showed a strong positive correlation with MS score among the groups. Further MS score correlated with indicators of insulin resistance evaluated. This study concluded that MS is highly prevalent among North-East Indian postmenopausal women seeking primary health care and its determinant factors related to age and sedentary habits. Thus recognizing and treating MS early with proper intervention can minimize complication.

Abstract
The objective of this study was to determine the effects of vitamin D3 plus calcium supplements (D3-calcium) on pharmacokinetics of isoflavones in Thai postmenopausal women. This study was an open-labeled, randomized three-phase crossover study. Twelve healthy subjects were randomized to receive one of the following regimens: (a) a single dose of isoflavones, (b) a single dose of isoflavones, and D3-calcium, or (c) continuous D3-calcium for 7 days followed by a single dose of isoflavones on the 8th day. After a washout period, subjects were switched to receive the 2 remaining regimens according to their randomized sequences. Blood samples were collected before dose and at specific time points until 32 hours after isoflavone administration. Plasma was treated with β-glucuronidase/sulfatase to hydrolyze glucuronide and sulfate conjugates of daidzein and genistein. Plasma concentrations of daidzein and genistein were determined by high performance liquid chromatography. The estimated pharmacokinetic parameters of isoflavones were time to maximal plasma concentration (Tmax), maximal plasma concentration (Cmax), half-life (t1/2) and area under the plasma concentration-time curve (AUC). Tmax of daidzein and genistein after regimen B was significantly longer than that of regimen A. Other pharmacokinetic parameters of daidzein and genistein obtained following the three regimens were not significantly different.

Abstract
Objectives: The purpose of this study is to determine the effect of a multimodal intervention (including the Women’s Wellness Program) on increasing levels of physical activity in Iranian midlife women. Study design: This 12-week study was conducted in women aged 50–65 years living in the general population. Women who were allocated to the intervention group (n = 40) received an intervention, which combined a multimodal program of physical activity and health education. Women in the control group continued their normal physical activities (n = 45). Mean outcome measure: The women completed a questionnaire that included measures for items of interest for this analysis, such as menopausal status, sociodemographic, and exercise and activity levels. Results: Analysis of covariance indicated that the intervention was effective in improving women’s physical activity. The test showed that there was a significant difference between intervention and control in current vigorous activity. Conclusion: Physical activity should be encouraged for prevention and reduction of risks for chronic disease and for improvement of health in midlife women. The multimodal intervention program may offer implications for designing and implementing exercise interventions in further studies.

Abstract
Two kinds of evidence suggest that female fertility may end at an earlier age in modern people than in ancestral populations or in our closest living relatives, chimpanzees. We investigate both to see whether fertility schedules or ovarian follicle counts falsify the alternative hypothesis that the age of terminal fertility changed little in the human lineage while greater longevity evolved due to grandmother effects. We use 19th century Utah women to represent non-contracepting humans, and compare their fertility by age with published records for wild chimpanzees. Then we revisit published counts of ovarian follicular stocks in both species. Results show wide individual variation in age at last birth and oocyte stocks in both humans and chimpanzees. This heterogeneity, combined with interspecific differences in adult mortality, has large and opposing effects on fertility schedules. Neither realized fertility nor rates of follicular atresia stand as evidence against the hypothesis that ages at last birth changed little while greater longevity evolved in our lineage.

Abstract
INTRODUCTION Biochemical markers of bone turnover (BTMs) are important in determining fracture risk in postmenopausal women; high levels being associated with increased risk. A proposed goal of anti-resorptive therapy is to reduce BTMs to the lower half of the reference range for healthy young pre-menopausal women. Our aims were a) to establish reference ranges for bone alkaline phosphatase (bone ALP), crosslinked C- and N-telopeptides of type I collagen (betaCTX, NTX), osteocalcin (OC) and procollagen type I N propeptide (PINP) in pre-menopausal women and b) to investigate the determinants of these BTMs. METHODS BTMs were measured in peripheral blood and second morning void urine collected from 200 healthy pre-menopausal women ages 30 to 45 years. Each subject completed a short medical and lifestyle questionnaire. RESULTS BTMs were higher before the age of 35 years than after it. BTMs were higher in women with low BMI (betaCTX and OC), low alcohol consumption (PINP), current smoking habit (bone ALP and NTX), and around time of ovulation (NTX). CONCLUSIONS We recommend that the age range 35 to 45 years should be used when establishing BTM reference ranges in women.

Abstract
UNLABELLED Gender-dependent differences in platelet count have been demonstrated in few studies. In women platelet count is higher than in men, which seems to reflect different hormonal profiles or a compensatory mechanism associated with menstrual blood loss. The aim of the study was to assess platelet count, mean platelet volume and thrombocytopoietic indices in women and men. The study was conducted on healthy blood donors divided into groups: F - 60 women and M - 65 men. Platelet count and mean platelet volume were determined on a haematological analyser Advia 120, Bayer. The following thrombocytopoietic indices were measured: thrombopoietin concentration (ELISA), percentage of reticulated platelets (flow cytometry, COULTER EPICS XL) and absolute reticulated platelet count. RESULTS Higher platelet count was noted in the group of women 252.35 +/- 41.25 x 10(9)/l as compared to men 221.87 +/- 37.63 x 10(9)/l (p = 0.0002). At the same time women had lower thrombopoietin concentration 156.50 +/- 57.18 pg/ml compared to men 180.46 +/- 60.98 pg/ml, (p = 0.03). No statistically significant differences were found in the mean platelet volume, percentage of reticulated platelets or absolute reticulated platelet count between group F and M. CONCLUSIONS Platelet count is gender-dependent, being higher in women than in men. Thrombopoietin concentration is gender-dependent and is lower in women than in men. In physiological conditions, there is no correlation between platelet count and thrombopoietin concentration in women (r = -0.155) and men (r = -0.2586).

Abstract
OBJECTIVE To evaluate the impact that administration of transdermal estradiol gel combined with medroxyprogesterone acetate (MPA) has on hemostasis. METHODS In this open prospective longitudinal study, thirty postmenopausal women received transdermal estradiol gel (1 mg/day) continuously combined with oral MPA (5 mg/day) for 12 days/month. The following parameters were determined: prothrombin time (PT), activated partial thromboplastin time (aPTT), factors VII, X, and XII activity, fibrinogen levels, thrombin-antithrombin complex levels, protein C and S antigen, antithrombin activity, plasminogen activator inhibitor type 1 (PAI-1) antigen, tissue-type plasminogen activator (t-PA) antigen, plasminogen activity and fibrin degradation products (FbDP) antigen. They were evaluated before and after 6 months of treatment. RESULTS There was a significant decrease in factor VII activity (P=0.001), factor X activity (P=0.016), protein C antigen (P=0.022), antithrombin activity (P=0.025), plasminogen activity (P=0.023), t-PA antigen (P=0.043) and FbDP antigen (P=0.048) compared with baseline values. CONCLUSION The results suggest that the treatment with transdermal estradiol gel combined with MPA avoids any major activation of coagulation and does not produce any overall effect on fibrinolysis. Therefore, this treatment might provide interesting effects on hemostasis in postmenopausal Brazilian women.
