ABSTRACT: Objective
To determine the association between hormone therapy (HT) and physical quality of life (QOL) in postmenopausal women with multiple sclerosis (MS).Methods
We included female participants from the prospective Nurses' Health Study, with a diagnosis of definite or probable MS, who had completed a physical functioning assessment (PF10; subscale of the 36-Item Short-Form Health Survey QOL survey) at a time point between 3 and 10 years after their final menstrual period (early postmenopause). We assessed the association between HT use at this time point (never vs at least 12 months of systemic estrogen with/without progestin) and both PF10 and the 36-Item Short-Form Health Survey Physical Component Scale. We used a linear regression model adjusting for age, MS duration, menopause type and duration, and further for additional covariates (only ancestry was significant).Results
Among 95 participants meeting all inclusion criteria at their first postmenopausal assessment, 61 reported HT use and 34 reported none. HT users differed from non-HT users in MS duration (p = 0.02) and menopause type (p = 0.01) but no other clinical or demographic characteristics. HT users had average PF10 scores that were 23 points higher than non-HT users (adjusted p = 0.004) and average Physical Component Scale scores that were 9.1 points higher in the 59 women with these available (adjusted p = 0.02). Longer duration of HT use was also associated with higher PF10 scores (p = 0.02, adjusted p = 0.06).Conclusions
Systemic HT use was associated with better physical QOL in postmenopausal women with MS in this observational study. Further studies are necessary to investigate causality.

Project description:BACKGROUND:It is known that the elderly population remains most of the time in light activity. Physical activity plays a key role in the primary prevention of chronic diseases to mitigate various deleterious effects of aging and improve quality of life. The objective of the present study was to evaluate whether the time that postmenopausal women remain in light activities during the day are related to better quality of life and compare these results with the quality of life of those who remain longer in moderate intensity and vigorous activity. METHODS:This is a cross sectional study there were evaluated 102 women, aged 50 to 79?years, all postmenopausal. Physical activity was measured by triaxial accelerometers. The quality of life was assessed using a Brazilian validated version of the SF-36 questionnaire. The sample was divided in three groups (G1, G2 and G3) according to tercile of time spent per week on light, moderate and moderate+vigorous physical activity. The comparisons between groups were made by ANOVA One Way, and the relationship between variables were made through the Spearman's correlation coefficient, and the significance was set at 5%. RESULTS:We found that the amount of time of light physical activity shows a higher correlation values compared to the moderate and moderate+vigorous physical activity (p?<?0,05) and presented significant correlation in all domains of quality of life. Vigorous physical activity did not presented significant correlation in all domains of quality of life. CONCLUSION:Our data suggests that light intensity physical activity presented influence on the quality of life of postmenopausal women. TRIAL REGISTRATION:(NCT02804308).

Project description:Title: Transcriptome analysis of human endometrial tissues from healthy post-menoupausal women reflecting the endometrial response to 3-weeks treatment with tibolone, E2 and E2+MPA. In an observational, open, non-randomized, controlled study uterine tissues were collected in order to generate endometrial gene expression profiles. healthy postmenopausal women were enrolled into the following treatment groups: Control-group; Tibolone-group, 2,5 mg of tibolone (administered orally) every day, starting 21 days prior to surgery; Estradiol-group, 2 mg of estradiol (administered orally) every day, starting 21 days prior to surgery; Estradiol+progestagen-group, 2 mg of estradiol (administered orally) and 5 mg of MPA (Medroxy Progesteroneacetate, administered orally) every day, starting 21 days prior to surgery. Pure (100%) endometrium was isolated from the snap-frozen uterine tissues and used for RNA isolation. RNA was labeled and hybridized to whole genome Affymetrix U133plus2 GeneChips containing 54,614 probe sets, representing approximately 47,000 transcripts. Relative to the control group, 940 genes are regulated in the endometrium of E2 treated patients, whereas only 198 genes are significantly regulated in endometria from tibolone or E2+MPA treated patients. Furthermore, only 9% of E2 regulated genes are also regulated by tibolone (85 out of 940), only 5% are also regulated by E2+MPA treatment and the overlap between tibolone and E2+MPA treatment is about 10%. This indicated that tibolone-treatment results in a weak endometrial profile similarity to E2 treatment and no profile similarity to E2+MPA treatment. A more detailed analysis showed that down stream processes, such as regulation of the cell cycle, angiogenesis and cell proliferation are almost not affected by tibolone treatment but, in contrast, are significantly affected by E2. For example, upon staining with Ki67, a marker for mitotic activity, significantly increased stromal as well as glandular cell proliferation was observed in the endometria from the E2-only treated group, while tibolone treatment resulted only in a slight increase in stromal cell proliferation (and no increase in glandular cell proliferation). These results indicate that in contrast to long-term tibolone use, short-term (21-days) use results in some estrogenic stimulation of the endometrium, which is clearly far less and rather different from what is observed during E2 treatment.

Project description:ImportanceMenopause is associated with biological aging, and hormone therapy (HT) is associated with health outcomes in postmenopausal women.ObjectiveTo evaluate the association between HT use and discrepancies between chronological and biological age in postmenopausal women as well as the potential modifying role of socioeconomic status (SES).Design, setting, and participantsThis population-based, retrospective cohort study included postmenopausal women registered in the UK Biobank. A baseline survey on HT use and biological aging biomarkers was conducted from March 2006 to October 2010. Data analyses were conducted in December 2023.ExposuresInformation regarding HT use, the age at starting HT, and HT duration was collected via a touchscreen questionnaire. SES was evaluated by education, family income, occupation, and the Townsend Deprivation Index.Main outcomes and measuresBiological aging discrepancy was evaluated using validated phenotypic age, which was calculated using chronological age and 9 biomarkers measured at baseline. All-cause and cause-specific mortality were also assessed.ResultsAmong the 117 763 postmenopausal women (mean [SD] age, 60.2 [5.4] years), 47 461 (40.3%) ever used HT. The mean phenotypic age was 52.1 (7.9) years. Ever use of HT was associated with a smaller biological aging discrepancy than never use of HT (β, -0.17 years; 95% CI, -0.23 to -0.10 years). This smaller aging discrepancy was more evident in those who started HT at age 55 years or older (β, -0.32 years; 95% CI, -0.48 to -0.15 years) and in those who used HT for 4 to 8 years (β, -0.25 years; 95% CI, -0.35 to -0.15 years). The association between HT and a smaller aging discrepancy was more evident in women with low SES, with a significant interaction observed for education (higher education: β, -0.08 years [95% CI, -0.17 to 0.01]; other education: β, -0.23 [95% CI, -0.32 to -0.14] years; P for interaction = .02). Phenotypic aging discrepancy mediated 12.7% (95% CI, 6.3% to 23.9%) of the association between HT and all-cause mortality and cause-specific mortality.Conclusions and relevanceIn this study, postmenopausal women with historical HT use were biologically younger than those not receiving HT, with a more evident association observed in those with low SES. The biological aging discrepancy mediated the association between HT and decreased mortality. Promoting HT in postmenopausal women could be important for healthy aging.

Project description:Prior epidemiologic studies suggest that regular use of analgesics may decrease risk of breast and ovarian cancer. We explored possible hormone-mediated mechanisms for these associations by examining the relationship between use of aspirin, nonaspirin nonsteroidal anti-inflammatory drugs (NSAID), and acetaminophen and sex steroid hormone concentrations among 740 postmenopausal women in the Nurses' Health Study. All women reported their analgesic use in 1988 or 1990 and provided a blood sample in 1989 to 1990. We calculated adjusted geometric mean estrogen and androgen levels for each category of analgesic use and calculated the P value for trend with increasing frequency of use. There was no association between days of use per month of aspirin, nonaspirin NSAIDs, or acetaminophen in 1990 and hormone levels (all P(trend) > or = 0.09). However, we observed significant inverse trends between the estimated number of aspirin tablets per month in 1988 and concentrations of estrone (P(trend) = 0.04) and estrone sulfate (P(trend) = 0.03). In analyses of total (aspirin and nonaspirin) NSAID use in 1990, women who used NSAIDs at least 15 days per month had significantly lower levels of estradiol compared with women with no NSAID use (P(trend) = 0.03). Frequency of use of all analgesics (aspirin, nonaspirin NSAIDs, and acetaminophen) in 1990 was inversely associated with concentrations of estradiol (P(trend) = 0.001), free estradiol (P(trend) = 0.01), estrone sulfate (P(trend) = 0.03), and the ratio of estradiol to testosterone (P(trend) = 0.04). Among postmenopausal women, regular users of aspirin and other analgesics may have lower estrogen levels than nonusers, which could contribute to a decreased risk of breast or ovarian cancer among analgesic users.

Project description:BackgroundFatigue, inactivity, and falls are major health issues for people with multiple sclerosis (MS). We examined the extent to which fatigue and low walking activity are associated with quality of life and increased fall risk in people with MS.MethodsPeople with MS (N = 210, aged 21-74 years) were categorized as having either high or low reported fatigue and walking activity levels and were then followed up for falls using monthly fall diaries for 6 months.ResultsA high level of fatigue was significantly associated with higher MS Disease Steps scores, worse balance, high composite physiological (Physiological Profile Assessment) fall risk scores, greater fear of falling, lower World Health Organization Disability Assessment Schedule (WHODAS) quality of life scores, and more prospectively recorded falls. Low walking activity was significantly associated with higher MS Disease Steps scores, reduced proprioception, worse standing and leaning balance, slow stepping, slow gait speed, worse fine motor control, high Physiological Profile Assessment fall risk scores, more fear of falling, and lower WHODAS quality of life scores.ConclusionsIncreased fatigue and low walking activity levels were significantly associated with increased fall risk and lower quality of life in people with MS. Interventions aimed at addressing fatigue and inactivity may have multiple benefits for this group.

Project description:Context:Evidence supports a protective effect of menopausal hormone therapy (HT) on bone. However, whether genetic susceptibility modifies the association of HT and fracture risk is not sufficiently explored. Objective:The objective was to test an interaction between genetic susceptibility and HT on fracture risk. Design:We constructed two weighted genetic risk scores (GRSs) based on 16 fracture-associated variants (Fx-GRSs) and 50 bone mineral density variants (BMD-GRSs). We used Cox regression to estimate the main effects of GRSs and their interactions with HT on fracture risk. We estimated the relative excess risk due to interaction (RERI) as a measure of additive interaction. We also used the case-only approach to test for a multiplicative interaction. Setting:Forty US clinical centers. Participants:A total of 9922 genotyped white postmenopausal women (age, 50 to 79) from the Women's Health Initiative HT randomized trials. Main Outcome Measures:Adjudicated fracture incidence. Results:Both GRSs were associated with fracture risk per 1-unit increment in GRS (hazard ratio, 1.04 [95% confidence interval, 1.02 to 1.06] for Fx-GRS and hazard ratio, 1.03 [95% confidence interval,1.02-1.04] for BMD-GRS). We found no evidence for multiplicative interaction for either of the GRS. However, we observed a substantial additive interaction, where the highest quartile of both GRSs and randomization to placebo have excess fracture risk: Fx-GRS P for RERI = 0.047, BMD-GRS P for RERI = 0.046. Conclusions:These results suggest that HT reduces fracture risk in postmenopausal women, especially in those at highest genetic risk of fracture and low BMD.

Project description:BACKGROUND:Sexual function is a component of quality of life, and sexual dysfunction entails reduced satisfaction with life and impaired mood and quality of relationships and affects not only the individual's quality of life, but her partner's life as well. Since Sexual Dysfunction (SD) is among the most common complaints of patients with Multiple Sclerosis (MS), this study was conducted to determine the prevalence of SD among women with MS and its effect on quality of life. MATERIALS AND METHODS:This cross-sectional study was conducted in 2018 on 300 women with MS aged 22-50?years in Isfahan, Iran, selected through systematic random sampling. Data were collected using the standard Female Sexual Function Index (FSFI) and MSQOL-54 and analyzed in SPSS using descriptive and analytical statistics. RESULTS:The overall prevalence of SD was found as 69.8% in women with MS, with the dimension of sexual desire being affected in 38.6% of the cases, sexual arousal in 38.6%, lubrication in 23.7%, orgasm in 37.3%, satisfaction in 23.4% and pain in 16.9%. SD was found to have significant relationships with age, duration of marriage, fatigue, EDSS and the combined physical and mental health aspects of quality of life (P?<? 0.05). Moreover, logistic regression analysis revealed that there was a higher probability of a sexual dysfunction among patients with MS and a high fatigue score [1.228(1.003 to 1.504); P?=?0.047]. The mean score of the combined physical and mental health aspects of quality of life was lower in the group of women with MS and SD compared to those without SD, and the difference between the two groups was statistically significant (P?<? 0.05). CONCLUSION:Sexual dysfunction is highly prevalent among women with MS and affects various dimensions of quality of life. Greater attention should be paid to the sexual problems faced by MS patients in order to improve their quality of life.

Project description:The aim of this study was to assess risks and benefits of conjugated equine estrogens (CEE) and medroxyprogesterone acetate (MPA) in postmenopausal Chinese women.A retrospective cohort study was undertaken using the Taiwan National Health Insurance Research Database, a population-based healthcare claims dataset. Eligible women aged 50 to 79 years were classified as exposed to CEE 0.625 mg/day with MPA 5.0 mg/day (estrogen [E] + progestin [P], n = 4,712) or CEE 0.625 mg/day only (E-only, n = 1,208) and were age-matched to unexposed women (n = 10,125). Follow-up was complete in 96% of the participants. The primary outcomes were coronary heart disease (CHD) and invasive breast cancer. The global index summarized risks of primary outcomes, stroke, pulmonary embolism, colon and endometrial cancers, hip fractures, and death. Time-to-event analyses were performed.Median durations of exposure in the E + P and E-only groups were 6.9 and 9 months, respectively. Median follow-up was 110 months. Hazard ratios (95% CI) for E + P exposure were as follows: myocardial infarction, 0.78 (0.51-1.19); CHD death, 1.21 (0.53-2.70); breast cancer, 1.48 (1.20-1.83); global index, 0.79 (0.72-0.87). Hazard ratios for E-only exposure were as follows: myocardial infarction, 0.76 (0.35-1.68); CHD death, 0.57 (0.11-2.80); breast cancer, 1.44 (0.99-2.10); global index, 1.09 (0.92-1.28). Per 10,000 person-years, there were 12 excess breast cancer cases with E + P exposure; there were 39 fewer global index events with E + P exposure. Adjusting for age, statin and aspirin use, hypercholesterolemia, diabetes, and hypertension did not significantly change estimates.In postmenopausal Chinese women, CEE with or without MPA was not associated with increased rates of CHD, but CEE with MPA may be associated with a higher breast cancer rate. E + P exposure conferred lower global index event rates.

Project description:Postmenopausal changes in the hormonal milieu in women with or without hormone therapy are hypothesized to be the pathway for a number of menopause-associated modifications in physiology and disease risk. Physical activity may modify these changes in women's hormone profiles. The crucial yet complex relationship between physical activity and physiologic and pharmacologic sex hormone levels in postmenopausal women has not been investigated sufficiently.Using structured recall, physical activity was assessed longitudinally during a period of 2 years in 194 postmenopausal women (90 randomized to 1 mg 17?-estradiol treatment daily and 104 randomized to placebo) in the Estrogen in the Prevention of Atherosclerosis Trial. The levels of physical activity were correlated with the serum sex hormone and the serum hormone-binding globulin levels in each treatment group.Among the placebo-treated women, total energy expenditure was positively associated with sex hormone-binding globulin (SHBG; P < 0.001) and inversely associated with testosterones (total, bioavailable, or free) and androstenedione (P < 0.001 for all), as well as with estradiol (P = 0.02). In estradiol-treated women, estradiol levels were inversely associated with total energy expenditure (P = 0.002) and weekly hours spent in moderate or more vigorous physical activity (P = 0.001).Physical activity is associated with lower serum levels of estradiol in both hormone therapy-treated and untreated women. In placebo-treated women only, physical activity is associated with reduced androgen levels and elevated SHBG levels.

Project description:Background and purposeSex differences in multiple sclerosis (MS) prevalence and disease course are thought to be driven by hormones. Exogenous exposure to estrogens may affect MS disease course. Thus, our aim was to investigate the association between hormone therapy (HT) and disease activity and disability accrual among women with MS.MethodsA register-based cohort study was conducted with prospectively enrolled cases from the Danish MS registry. Information on hormone exposure was retrieved from the National Prescription Registry. Outcomes were relapse rate, relapse rate ratio, recurrent relapses, 6-month confirmed and sustained Expanded Disability Status Scale (EDSS) milestones 4 and 6, and recurrent EDSS worsening.ResultsIn all, 3325 women were eligible for analyses, of whom 333 (10%) were ever on HT at some time during follow-up. We found no association between HT and disability accrual, although a trend for increasing risk with increasing length of use was seen. The risk of reaching 6-month confirmed and sustained EDSS 4 among users was 0.6 (95% confidence interval [CI] = 0.3-1.2) after <1 year of use and 1.4 (95% CI = 0.9-2.2) after >5 years of HT compared to never use. The risk of recurrent relapse was increased by 20% (95% CI = 1.0-1.4) among current users of HT compared to nonusers. However, the risk of recurrent relapses was driven by the first calendar period (1996-2005) before the introduction of high-efficacy disease-modifying therapy.ConclusionsOur findings from this nationwide MS population suggest that HT does not affect disability accrual in women with MS, especially if used for <5 years.
