Filter by:The aim of the study will be comparing the effectiveness of two diets: moderate in fat with a high proportion of monounsaturated fatty acids (MUFAs) - the Mediterranean diet (MED) and 2) the low in fat and high in dietary fiber contents the dietary approaches to stop hypertension diet (DASH) on weight maintenance and cardiovascular risks following a recent body weight reduction in centrally obese postmenopausal women. The tested diets will be given ad libitum manner. Moreover, adherence to both prescribed weight-loss maintenance diets will be also evaluated by the plasma concentration of alkylresorcinols (AR) as a possible whole grain wheat/rye dietary biomarker and by the analysis of fatty acids profile in erythrocyte membranes as a dietary biomarker of a fatty acids consumption. The participants of this study will be 150 non-smoking, postmenopausal women with central obesity, who wished to lose weight and have at least one other criterion of metabolic syndrome. The intervention will include 3 phases: Phase I (weeks 1-8), weight loss dietary intervention with 700 kcal/d energy deficit, Phase II (week 9-32), weight loss maintenance intervention for those participants losing ≥10% initial body weight the MED or the DASH diet will be offered in a random manner. The control group will receive oral dietary recommendations based on the Harvard model "Healthy Eating Plate". After this 32 weeks period will be finished, the participants will be discharged to the community with no contact by study personnel, until the 52-weeks follow-up period (Phase III).
Urinary tract infections (UTIs) are bothersome and more likely to occur in postmenopausal women. Frequent UTIs, as well as other problems with the urinary and genital systems such as painful sex and urinary frequency/urgency, are part of a symptom complex called genitourinary syndrome of menopause (GSM). Prasterone (Intrarosa®) is a man-made steroid that helps with painful sex in postmenopausal women. Because previous studies have shown prasterone to help with other GSM problems, this study was designed to investigate if prasterone used in the vagina decreases the number of UTIs in postmenopausal women.
This study intends to evaluate the impact of resistance training variable manipulation (intensity and volume) on body composition, fatigability and functional capacity in postmenopausal breast cancer survivors.
Sustainability of vaginal ultra-low dose estrogen therapy in postmenopausal women
Osteoporosis is a large public health disease, characterized by low bone mass and micro architectural deterioration of bone tissue, resulting in enhanced bone fragility and consequent increase in fracture risk. Osteoporosis is present when bone mineral density (BMD) or content (BMC), measured by dual-energy X-ray absorptiometry (DXA), is more than 2.5 SDs below the mean value of the young adult. BMD measured by DXA is a surrogate measure of bone strength and is the primary determinant of fracture risk in both men and women. However, the majority of fragility fractures occur in women and in individuals who do not have osteoporosis according to these standards, indicating that BMD is just one among several indicators of bone health and that assessment of fracture risk should also rely on other bone properties. Newer imaging methods, such as quantitative computerized tomography (QCT), can complement information from DXA-measurements due to its ability to assess volumetric BMD and bone geometry and to differentiate between cortical and trabecular bone compartments. Bones are composite materials made predominantly of living cells, extracellular matrix, water and lipids. This composite nature of the bone material enables it to absorb stresses by elastic deformation and to endure high loads before fracturing. A new in vivo measurements of bone material strength can be used to evaluate bone mechanical properties and thereby the fracture risk. It is well established that the skeleton benefits, in terms of increased density, from regular physical activity. However, changes in BMD are still the main surrogate for assessing improvements in exercise-induced bone health despite the experimental findings as well as findings in humans showing that improvements in mechanical bone properties are independent of changes in BMD. These improvements in mechanical bone properties may be due to changes in bone shape or matrix composition. It could then be argued that a decrease in BMD is only one of the possible manifestations of osteoporosis and that bone strength or fragility is multifactorial. The objective for this study is to investigate the role of mechanical loading on bone material strength and bone microarchitecture in middle-aged women. The overall hypothesis is that mechanical loading is a regulator of bone material strength and microarchitecture in middle-aged women. This is an intervention study where the participants will act as their own controls. The investigators intend to include 40 postmenopausal and healthy women 50-60 years of age in the study. Advertisements in local papers and at the hospital will be used to come into contact with suitable study subjects. The women will be asked to perform an intervention program, including jumping on one leg every day during a 3-month period according to a protocol with a gradually increasing load/number of jumps. The women have to choose one of their legs as intervention-leg and stick to the chosen leg throughout the study. The leg without intervention will be used as a control. Both bone material strength (BMS) and bone microarchitecture will be measured before and after intervention in both legs (tibia). The operators measuring BMS (OsteoProbe®) and bone microarchitecture (high resolution pQCT) will be blinded concerning each participant's choice of leg for intervention. In addition, subjects will be asked to register daily physical activity in a structured diary. The primary outcome measure will be changes in bone material strength (BMS) in the lower leg (tibia) with intervention compared to the leg (tibia) without intervention. Participants will attend two clinic visits, at baseline and after 3 months when the intervention period is completed. The secondary outcome measures will be changes in total volumetric density, cortical volumetric density, cortical cross sectional area and trabecular bone volume fraction in the lower leg (tibia) with intervention compared to the leg (tibia) without intervention.
Alleged benefits experienced after the consumption of soy in Asian countries have been attributed to the isoflavone content of soy products. Amongst other benefits, isoflavones are believed to relieve menopausal symptoms and are therefore often consumed in supplement form in Western countries. These supplements contain relatively high amounts of isoflavones and are on the market in different compositions. The question is whether supplements with different compositions exert similar effects or whether the effects differ substantially.
Up to 50% of all postmenopausal women, experience vaginal dryness, irritation, burning, itching or discomfort, which often make sex to become difficult or painful. These symptoms combined are known as vaginal atrophy. Vaginal atrophy is a consequence of the lining tissue of the vagina becoming thinner, drier, and less elastic due to the lack of estrogen. In addition, vaginal atrophy is associated with an increased pH, which creates an environment more susceptible to infections. The mucosal epithelium shows signs of severe atrophy and cytological examination demonstrate increased number of the basal and parabasal cells and reduced number of superficial cells. Estrogen treatment either as hormone replacement therapy or topical application is a common treatment for vaginal atrophy. However, some women experience adverse reactions such as uterine bleeding, perineal pain and breast pain and many women are also reluctant to use estrogens due to a general negative view to this topic in the society. Oxytocin is a peptide hormone, which is normally released into the circulation via the pituitary. The most well known effects of oxytocin are its roles in female reproduction such as facilitation of birth and breast feeding. In addition, oxytocin has in vitro been shown to exert positive effects on the proliferation of human vaginal mucosal cells from postmenopausal women. Considering the stimulatory effects of oxytocin on vaginal mucosal cell proliferation, topical application of oxytocin to the vaginal mucosa may be an approach to treat vaginal atrophy. In one previous placebo-controlled study on 20 postmenopausal women suffering from vaginal atrophy, a gel containing oxytocin for topical intra-vaginal administration was applied daily for seven days. The results indicated that for subjects receiving topical oxytocin the vaginal atrophy assessed by histological examination was reversed after treatment. A similar effect was not seen in the placebo group, which indicated a difference between placebo and active treatment. However, the limited number of exposed subjects in this pilot study necessitates a larger study in order to generate conclusive proof of concept data for the effects of oxytocin on vaginal atrophy. Due to the limitations of estrogens in the treatment of vaginal atrophy, many postmenopausal women are left without an effective remedy. Hence, there is a need for alternative non-estrogenic treatments of this indication. The present study is aiming to investigate the efficacy of topical oxytocin in the treatment of vaginal atrophy. The main objective of this study is to investigate if topical oxytocin can reverse vaginal atrophy, as assessed by cytological examination of the vaginal mucosal epithelium, in postmenopausal women after 12 weeks of treatment as compared to placebo.
This is cross-over, randomized clinical trial, with objective to evaluate the effects of low-dose oral hormone therapy and non-oral hormone therapy on endothelial function markers (fibrinogen, von Willebrand factor, c-reactive protein), natriuretic peptide and on anthropometric, metabolic and hormonal variables in early and healthy postmenopausal women and analyzing polymorphisms in the estrogen receptor gene and FTO polymorphisms Patients will be randomized to receive oral hormone treatment or non-oral hormone treatment The investigators hypothesis is that a different genotypes in the receptor estrogen gene and FTO may have an influences on treatment response in metabolic markers and cardiovascular risk
The study objective is, to evaluate the fractional absorption of calcium from amorphous calcium carbonate (ACC) Vs crystalline calcium carbonate (CCC) dietary supplements in postmenopausal women.
Alleged benefits experienced by the consumption of soy in Asian countries have been attributed to the isoflavone content of soy products. Amongst other benefits, isoflavones are believed to relieve menopausal symptoms and are therefore often consumed in supplement form in Western countries. These supplements contain relatively high amounts of isoflavones, and the question is if these concentrations still exert beneficial effects or whether negative effects become dominant. Therefore, the investigators will study the effect of intake of one dose of isoflavones, as compared to placebo, for eight weeks on gene-expression in Peripheral Blood Mononuclear Cells (PBMCs) in post-menopausal, equol-producing women.
