Abstract
The purpose of the present study was to compare next-morning responses of RMR and appetite to pre-sleep consumption of casein protein (CP) in pre- and postmenopausal women. The study was a randomised, crossover, double-blind, placebo-controlled trial. Seven sedentary premenopausal (age: 19·9 (sd 1·2) years; BMI: 23·1 (sd 2·6) kg/m2) and seven sedentary postmenopausal (age: 56·4 (sd 4·9) years; BMI: 26·3 (sd 3·5) kg/m2) women participated. During visit one, anthropometrics and body composition were measured. Following visit one, subjects consumed either CP (25 g) or placebo (PL) ≥2 h after their last meal and ≤30 min prior to sleep on the night before visits two and three. Visits two and three occurred ≥1 week after visit one and were 48 h apart. During visits two and three, RMR (VO2), RER and appetite were measured via indirect calorimetry and visual analogue scale, respectively. Anthropometrics and body composition were analysed by one-way ANOVA. RMR and measures of appetite were analysed using a 2 × 2 (menopause status × CP/PL) repeated-measures ANOVA. Significance was accepted at P ≤ 0·05. RMR was significantly lower in postmenopausal compared with premenopausal women under both conditions (P = 0·003). When consumed pre-sleep CP did not alter RMR, RER or appetite compared with PL when assessed next morning in pre- and postmenopausal women. These data contribute to growing evidence that pre-sleep consumption of protein is not harmful to next-morning metabolism or appetite. In addition, these data demonstrate that menopause may not alter next-morning RMR, RER or appetite after pre-sleep consumption of CP.

Acupuncture in medicine : journal of the British Medical Acupuncture Society. 2021;(1):30-40
Abstract
OBJECTIVE The aim of this study was to examine the effect of acupuncture on obesity-related parameters with regard to metabolomics. METHODS This two-arm parallel, patient- and assessor-blind, sham-controlled randomized clinical trial included 120 obese participants. Participants were randomized into two groups. The treatment group received a combined intervention of manual acupuncture (MA) plus electroacupuncture (EA), while the control group received a combination of sham acupuncture interventions consisting of sham MA plus sham EA for 6 weeks. The serum lipid levels were measured as the primary outcome measure and anthropometric parameters and serum metabolic profiles including amino acids and carnitines were measured as secondary outcome measures. RESULTS The serum lipid levels and anthropometric measurements did not significantly differ between groups, while body weight, body mass index (BMI), and waist circumference were improved within each group and the level of high-density lipoprotein cholesterol increased over time in the treatment group. There were no significant differences in amino acid levels between groups, while certain carnitine (C2, C4, C6, and l-carnitine) levels were significantly increased (p < 0.05) in the treatment group compared to the control group. CONCLUSION In summary, 6 weeks of acupuncture treatment did not affect anthropometric and serum metabolic parameters, with the exception of certain carnitines, when compared to sham acupuncture. The observation of increased carnitine levels in the acupuncture group could result in potential long-term benefits to obese individuals. Additional studies are needed to investigate the long-term effects of acupuncture on lipid metabolism and the underlying mechanism of action. TRIAL REGISTRATION NUMBER This study is registered at ClinicalTrials.gov (NCT02066090).

Abstract
CONTEXT Consensus regarding diagnosis and management of osteoporosis in premenopausal women (PW) is still lacking due to few studies carried out in this population. DESIGN The European Calcified Tissue Society and the International Osteoporosis Foundation convened a working group to produce an updated review of literature published after 2017 on this topic. RESULTS Fragility fractures in PW are rare and mostly due to secondary osteoporosis (ie, in presence of an underlying disease such as hormonal, inflammatory, or digestive disorders). In absence of another disorder, low bone mineral density (BMD) together with fragility fractures qualifies as idiopathic osteoporosis. In contrast, low BMD alone does not necessarily represent osteoporosis in absence of bone microarchitectural abnormalities. BMD increases in PW with osteoporosis when the underlying disease is treated. For example, in celiac disease, an increase of 9% in radius trabecular volumetric density was achieved after 1 year of gluten-free diet, while anti-tumor necrosis factor alpha improved BMD in PW with inflammatory bowel diseases. In amenorrhea, including anorexia nervosa, appropriately delivered estrogen replacement therapy can also improve BMD. Alternatively, antiresorptive or anabolic therapy has been shown to improve BMD in a variety of conditions, the range of improvement (3%-16%) depending on skeletal site and the nature of the secondary cause. No studies were powered to demonstrate fracture reduction. The effects of bisphosphonates in childbearing women have been scantly studied and caution is needed. CONCLUSION The majority of PW with osteoporosis have an underlying disease. Specific therapy of these diseases, as well as antiresorptive and anabolic drugs, improve BMD, but without evidence of fracture reduction.

Sandoughi, M, Kaykhaei, MA, Langarizadeh, E, Dashipour, A
International journal of rheumatic diseases. 2020;(12):1692-1697
Abstract
AIM: Chronic inflammation and subsequent use of glucocorticoids can lead to relative adrenocortical insufficiency in patients with rheumatoid arthritis (RA). Previously, adrenocortical hormone, dehydroepiandrosterone (DHEA) was shown as a potential therapy for autoimmune disorders. However, data regarding effects of DHEA in RA are limited. The aim of this study was to investigate the effects of DHEA on quality of life (QOL) in premenopausal rheumatoid arthritis patients. METHOD In this randomized double blinded, controlled trial 46 premenopausal rheumatoid arthritis patients were assigned to receive 50 mg/d DHEA (23 patients) or placebo (23 patients) for 12 weeks. Disease Activity Score of 28 joints - erythrocyte sedimentation rate (DAS28-ESR) questionnaire, visual analog score and swollen and tender joint counts (both 0-28) were used for assessment of disease activity. Persian-validated World Health Organization Quality of Life Brief version (WHOQOL BREF) questionnaire was used to assess quality of life. RESULTS In comparison to the control group more improvement in QOL (P = .025) and environment health (P = .001) was observed in the DHEA group. After adjustment for age and disease duration DHEA was associated with more improvement in QOL (P = .01), psychological (P = .02) and physical health (P = .03). A trend toward a decrease in ESR was observed in DHEA group (P = .06). DAS was improved in both groups; however, there was no significant change in DAS28 between groups (P = .88). Frequency of adverse events albeit minor was similar in both groups. CONCLUSION Our study supports a slightly superior effect of DHEA over placebo to improve QOL in premenopausal female patients with rheumatoid arthritis. We did not find improvement in DAS in the DHEA group over placebo.

Abstract
METHODS A cross-sectional study was conducted among 185 participants: 88 premenopausal and 97 postmenopausal women obtaining healthcare service from Ho Teaching Hospital (HTH) and Ho Municipal Hospital from November 2018 to January 2020. Questionnaires were administered, and direct anthropometric measurements were taken. Blood samples were collected between 8:00 am and 10:00 am after overnight fast (12 to 18 hours; ≥8 hours) to assess fasting blood glucose, fasting lipids, alanine aminotransferase (ALT), aspartate aminotransferase (AST), and gamma-glutamyl transferase (GGT) concentrations at HTH laboratory using standard measuring procedures. This study in diagnosing metabolic syndrome and nonalcoholic fatty liver disease employed the National Cholesterol Education Program Adult Treatment Panel III (NCEP-ATPIII) criteria and the Bedogni fatty liver index algorithm, respectively. RESULTS The overall prevalence of MetS and NAFLD was 24.86% and 40.00% using NCEP-ATPIII and Bedogni fatty liver index algorithm, respectively. The prevalence of MetS and NAFLD among postmenopausal women was 32.99% and 49.48%, respectively, higher than 15.91% and 29.55%, respectively, observed among premenopausal women. The most prevalent MetS component among the study population was abdominal obesity (68.65%) which was significantly higher among the postmenopausal women (82.47%) than premenopausal women (53.41%) (<0.001). Hyperglycemia and hypertension were the major significant risk factors for developing MetS among premenopausal women whereas high triglyceride was the highest risk factor found among the postmenopausal women. Obesity and abdominal obesity were the most likely risk factors for developing nonalcoholic fatty liver disease among both premenopausal and postmenopausal women. Comorbidities of MetS and NAFLD were significant risk factors for developing cardiovascular diseases (CVD) (OR = 5.2, 95%CI = 2.2-12.4; p < 0.001). CONCLUSION This study established a significant association between coronary artery disease and comorbidities of MetS and NAFLD among the studied participants. Both conditions were found to be more prevalent among postmenopausal women compared to premenopausal women. Abdominal obesity was the most prevalent MetS component among the population. Women should be monitored for the two conditions and be educated on adopting healthy lifestyles to minimize the incidence of these conditions.

Sparkes, C, Sinclair, AJ, Gibson, RA, Else, PL, Meyer, BJ
Nutrients. 2020;(4)
Abstract
(1) Aim: the aim of this secondary analysis was to report the variability in response to n-3 long chain polyunsaturated fatty acids (LCPUFA) supplementation in erythrocytes, plasma and whole blood of a previously published dose response study. (2) Methods: a randomized, double-blind, placebo-controlled trial of parallel design was conducted, whereby pre-menopausal women were randomly assigned to consume 0, 0.35, 0.7 or 1 g/day of supplemental eicosapentaenoic acid (EPA) plus docosahexaenoic acid (DHA). Fasted blood samples were taken at baseline and after eight weeks intervention. Erythrocyte, plasma and whole blood fatty acids were extracted using the method of Lepage and Roy and analysed using gas chromatography. (3) Results: There were significant increases in EPA plus DHA levels in the 0.7 g and 1 g dose groups, with the highest increase with the 1 g dose notably: in erythrocytes (from 5.69% to 7.59%), plasma (from 2.94% to 5.48%) and in whole blood (from 3.81% to 6.03%). There was high variability in response to the supplement in erythrocytes, plasma and whole blood across the different doses. (4) Conclusion: there is high individual variability in n-3 LCPUFA levels in response to n-3 LCPUFA supplementation, which should be taken into account in clinical trials using n-3 LCPUFA supplements.

Ambikairajah, A, Walsh, E, Cherbuin, N
Menopause (New York, N.Y.). 2019;(11):1327-1333
Abstract
OBJECTIVES The aim of the study was to determine lipid profile differences between premenopausal and postmenopausal women. METHODS The present review used a meta-analytic approach. Sixty-six studies were included, which provided a total sample of 114,655 women consisting of 68,394 that were premenopausal and 46,261 that were postmenopausal. RESULTS The main findings were that (1) lipoproteins were significantly higher in postmenopausal women compared to premenopausal women including triglycerides (0.27 mmol/L, 95% confidence interval, 0.22-0.31), total cholesterol (0.58, 0.50-0.65), low-density lipoprotein (0.45, 0.38-0.53), and total cholesterol to high-density lipoprotein levels (0.39, 0.16-0.62); (2) there was no difference in high-density lipoprotein levels between premenopausal and postmenopausal women (0.02, -0.00-0.04); and (3) the differences in lipid levels was partly attributable to the mean age difference between premenopausal and postmenopausal women. CONCLUSIONS These findings are important as they provide precise estimates of lipid differences in women around menopause. Furthermore the results suggest that the unfavorable lipid profile that develops in postmenopausal women puts them at higher risk of cardiovascular disease such as heart disease and stroke if appropriate lifestyle/pharmacological interventions are not implemented.

Effect of Calcium Derived from Lithothamnion sp. on Markers of Calcium Metabolism in Premenopausal Women.
Zenk, JL, Frestedt, JL, Kuskowski, MA
Journal of medicinal food. 2018;(2):154-158
Abstract
A double-blind crossover pilot trial tested the hypothesis that botanically derived calcium could demonstrate greater influence over calcium metabolism markers compared with a nonplant-derived calcium carbonate supplement or placebo. Twelve fasting female subjects received a single oral dose of Aquamin F™ (derived from the marine algal Lithothamnion sp.), or calcium carbonate, or placebo. Blood and urine samples were collected at baseline and over 12 h to evaluate ionized and total calcium and parathyroid hormone (PTH). Subjects treated with Aquamin F demonstrated significantly greater urinary clearance of calcium after 12 h compared with placebo (P = .004). Following a meal at 90 min, subjects treated with Aquamin F demonstrated a more prolonged suppression of serum PTH concentration (significantly lower than placebo at 90, 120, and 240 min). Calcium carbonate provided an intermediate response; urinary clearance was not significantly different from placebo treatment and PTH was only significantly lower than placebo at 90 min. Aquamin F may demonstrate greater influence over these markers of calcium metabolism than calcium carbonate or placebo, as suggested by a greater calciuric response and a more prolonged suppression of serum PTH concentrations following a meal in premenopausal women.

Hormone molecular biology and clinical investigation. 2018;(1)
Abstract
Background Obesity-related alterations in the circulating steroid hormone profile remain equivocal in women. Our objective was to identify circulating steroid levels that relate to increased adiposity and altered adipose phenotype in premenopausal women. Materials and methods In a sample of 42 premenopausal women [age 46 ± 3 years; body mass index (BMI) 27.1 ± 4.2 kg/m2], 19 plasma steroids were quantified by electrospray ionization-liquid chromatography-tandem mass spectroscopy (ESI-LC-MS/MS). Body composition and fat distribution were assessed by dual-energy X-ray absorptiometry (DXA) and computed tomography (CT), respectively. Markers of adipose tissue function including adipocyte size distributions, radiological attenuation and macrophage infiltration were also analyzed in surgically obtained visceral and subcutaneous fat samples. Results Many negative correlations were observed between adiposity measurements such as BMI, body fat percentage or total abdominal adipose tissue area and plasma levels of androstenedione (Δ4) (r = -0.33 to -0.39, p ≤ 0.04), androsterone (ADT) (r = -0.30 to -0.38, p ≤ 0.05) and steroid precursor pregnenolone (PREG) (r = -0.36 to -0.46, p ≤ 0.02). Visceral adipocyte hypertrophy was observed in patients with low PREG concentrations (p < 0.05). Visceral adipose tissue radiologic attenuation, a potential marker of adipocyte size, was also positively correlated with PREG levels (r = 0.33, p < 0.05). Low levels of PREG were related to increased number of macrophages infiltrating visceral and subcutaneous adipose tissue (p < 0.05). Conclusion Plasma levels of androgens and their precursors are lower in women with increased adiposity and visceral adipocyte hypertrophy. Low circulating PREG concentration may represent a marker of adipose tissue dysfunction.

Abstract
BACKGROUND Soy phytoestrogens are potential alternatives to postmenopausal hormone replacement therapy (HRT). Adverse effects of HRT such as myocardial infarction, stroke, and pulmonary embolism are mediated by calcium-induced signaling. OBJECTIVE To determine whether soy isoflavones affect serum calcium in healthy female subjects. DESIGN In a double-blind trial, 197 premenopausal women were randomly assigned to either isoflavone (N = 99) or placebo pills (N = 98) 5 days per week for up to 2 years, plus prenatal vitamins. Isoflavone pills contained 60 mg genistein, 60 mg daidzein and 16.6 mg glycitein (expressed as aglycone equivalents). All pills contained 15 mg riboflavin as an adherence marker. Blood chemistries and urinary daidzein, genistein and riboflavin were measured multiple times during the luteal phase before and during treatment. RESULTS Analysis of the adherent population (N = 83 per group), revealed significantly strong associations between urinary levels of isoflavones and serum concentrations of calcium (regression coefficients 0.082 for daidzein and 0.229 for genistein, all P < 0.01) and chloride (regression coefficient, -1.537 for genistein, P < 0.0001), mediated in part by albumin. The effects amounted to mean changes of +0.24 mg/dL for calcium and -1.45 mEq/L for chloride, with each visit for subjects excreting the most vs. the least amounts of isoflavones. These associations were not evident in the intention-to-treat analysis (N = 197) that did not assess expected variations in isoflavone levels within and between subjects from metabolism and adherence. CONCLUSIONS These novel and strong effects of soy isoflavones on calcium homeostasis have important implications for long term effects of these natural substances on cardiovascular diseases.
