Abstract
OBJECTIVE Menopausal symptoms are common in midlife women and have broad impacts on their daily functioning and quality of life. Black cohosh extracts have been widely used to relieve menopausal symptoms. However, the comparative benefits of different combined black cohosh regimens remain inconclusive. The aim of the current updated meta-analysis is to address the comparative efficacies of different black cohosh regimens in improving menopausal symptoms. METHODS Random-effect model pairwise meta-analysis of randomized controlled trials was conducted to investigate the treatment effect on menopausal symptoms by the black cohosh extract both alone or combined with other related active ingredients. The outcomes studied were changes in menopausal symptoms after treatment with black cohosh extracts in menopausal women. RESULTS Twenty-two articles including information on 2,310 menopausal women were included in the analyses. Black cohosh extracts were associated with significant improvements in overall menopausal symptoms (Hedges' g = 0.575, 95% CI = 0.283 to 0.867, P < 0.001), as well as in hot flashes (Hedges' g = 0.315, 95% CIs = 0.107 to 0.524, P = 0.003), and somatic symptoms (Hedges' g = 0.418, 95% CI = 0.165 to 0.670, P = 0.001), compared with placebo. However, black cohosh did not significantly improve anxiety (Hedges' g = 0.194, 95% CI = -0.296 to 0.684, P = 0.438) or depressive symptoms (Hedges' g = 0.406, 95% CI = -0.121 to 0.932, P = 0.131). The dropout rate for black cohosh products was similar to that for placebo (odds ratio = 0.911, 95% CI = 0.660 to 1.256, P = 0.568). CONCLUSIONS This study provides updated evidence regarding the potentially beneficial effects of black cohosh extracts for relieving menopausal symptoms in menopausal women.

J Gen Intern Med 2022; 37:770-777. [PMID: 36042093 PMCID: PMC9481785 DOI: 10.1007/s11606-022-07592-4] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 06/29/2021] [Accepted: 04/01/2022] [Indexed: 11/30/2022]
Abstract
BACKGROUND Rates of suicide and unintended overdose death are high among midlife and older women, yet there is paucity of data identifying women at greatest risk. Psychoactive medications, commonly prescribed and co-prescribed in this population, may serve as salient indicators of risk for these outcomes. OBJECTIVE To determine whether long-term psychoactive medications and psychoactive polypharmacy predict risk of suicide and unintended overdose death among midlife and older women Veterans above and beyond other recognized factors. DESIGN Longitudinal cohort study PARTICIPANTS: Women Veterans aged ≥ 50 with at least one Veterans Health Administration (VHA) clinical encounter in FY2012-2013. MAIN MEASURES Long-term psychoactive medications (opioids, benzodiazepines, sedative-hypnotics, antidepressants, antipsychotics, and antiepileptics, prescribed for ≥ 90/180 days) and psychoactive polypharmacy (overlapping for ≥ 1 day) from VHA pharmacy records; suicide and unintended overdose death through December 31, 2018. KEY RESULTS In this national sample of 154,558 midlife and older women Veterans (mean age 63.4, SD 9.3 years), 130 died by suicide and 175 died from unintentional overdose over an average of 5.6 years. In fully adjusted models, long-term opioids (hazard ratio (HR) 2.01, 95% CI 1.21-3.35) and benzodiazepines (HR 2.99, 95% CI 1.82-4.91) were associated with death by suicide; opioids (HR 3.62, 95% CI 2.46-5.34), benzodiazepines (HR 2.77, 95% CI 1.73-4.42), sedative-hypnotics (HR 1.87, 95% CI 1.06-3.29), antidepressants (HR 1.47, 95% CI 1.03-2.12), antipsychotics (HR 1.81, 95% CI 1.02-3.22), and antiepileptics (HR 2.17, 95% CI 1.48-3.19) were associated with unintended overdose death. Women who were co-prescribed ≥ 3 psychoactive medications had over 2-fold increased risk of suicide (HR 2.83, 95% CI 1.65-4.84) and unintended overdose death (HR 2.60, 95% CI 1.72-3.94). CONCLUSIONS Long-term psychoactive medications and psychoactive medication polypharmacy were important indicators of risk for death by suicide and death by unintended overdose among midlife and older women Veterans, even after accounting for psychiatric and substance use disorders.

Abstract
BACKGROUND The greatest increases in long-term opioid use and opioid-related overdose mortality in recent years have been among women in midlife. Common menopausal symptoms broadly affect health and health care utilization in midlife, but their contribution to chronic pain management during this period is unknown. OBJECTIVE To examine relationships between menopausal symptoms and long-term opioid prescription patterns among midlife women with chronic pain. DESIGN Cross-sectional analysis of national Veterans Health Administration medical and pharmacy records (2014-2015). PARTICIPANTS Women Veterans aged 45-64 with ≥ 1 outpatient visit and chronic pain diagnoses spanning ≥ 90 days. MAIN MEASURES Long-term opioids (prescribed oral opioids for ≥ 90 days), high-dose long-term opioids (> 50 mg average morphine equivalent daily dose), and long-term opioids co-prescribed with central nervous system depressants (benzodiazepine and non-benzodiazepine sedative-hypnotics, gabapentin/pregabalin, muscle relaxants). Multivariable logistic regression models were used to examine associations between outcomes and menopausal symptoms (menopausal symptom-related diagnoses (i.e., "symptomatic menopausal states") on ≥ 2 encounters and/or menopausal hormone therapy, adjusting for race, age, body mass index, and mental health and substance use disorder diagnoses. KEY RESULTS In this national sample of 104,984 midlife women Veterans with chronic pain (mean age 54.5, SD 5.4 years), 17% had evidence of menopausal symptoms, 51% were prescribed long-term opioids, 13% were prescribed high-dose long-term opioids, and 35% were co-prescribed long-term opioids and central nervous system depressants. In multivariable analyses, women with menopausal symptoms had increased odds of long-term opioids (OR 1.21, 95% CI 1.18-1.26), high-dose long-term opioids (OR 1.08, 95% CI 1.02-1.13), and long-term opioids co-prescribed with central nervous system depressants (sedative-hypnotics OR 1.25, 95% CI 1.22-1.30; gabapentin/pregabalin OR 1.23, 95% CI 1.20-1.27; muscle relaxants OR 1.24, 95% CI 1.20-1.28). CONCLUSIONS Among midlife women Veterans with chronic pain, evidence of menopausal symptoms was associated with potentially risky long-term opioid prescription patterns, independent of known risk factors.

Abstract
This study evaluated the efficacy of red clover to relieve hot flashes and menopausal symptoms in peri/postmenopausal women. Electronic databases (MEDLINE, Scopus and the Cochrane Library) were searched. The mean frequency of hot flashes in red clover groups was lower compared with that in the control groups (close to statistical significance). Difference in means (MD) of hot flashes frequency was - 1.99 (- 4.12-0.139; p = 0.067; heterogeneity P > 0.01; I(2) = 94.93%; Random effect model). Subjective (vaginal dryness) and objective (maturation value) symptoms of vaginal atrophy showed a significant improvement with 80-mg dose of red clover. Red clover showed less therapeutic effect on psychology status, sexual problems and sleeping disorders. Red clover consumption may decrease frequency of hot flashes, especially in women with severe hot flashes (≥ 5 per day). Red clover may reduce other menopausal symptoms. Further trials are needed to confirm the current systematic review findings.

Abstract
AIMS Review controlled clinical trials of isoflavones and amino acid preparation effects on hot flashes and at least one other symptom including mood, sleep, pain, and cognitive function that women report during the menopausal transition and early postmenopause. METHODS An experienced reference librarian searched PubMed/Medline, CINAHL Plus, PsycInfo, Cochrane Database of Systematic Reviews, Cochrane Central Register of Controlled Trials, Web of Science, EMBASE, AMED, and Alt-Health Watch for English-language randomized controlled trials between 2004 and July 2011. Seventeen trials of isoflavones and amino acid effects on hot flashes and one additional symptom were identified. RESULTS In five trials of soy isoflavone preparations, two (6g soy germ extract and 25 g soy protein in soy nuts) significantly decreased hot flashes, but no other symptoms. In the seven trials of other isoflavones, six significantly reduced hot flashes; in addition, red clover (80 mg) significantly reduced mood symptoms; Rexflavone (350 mg) for women with Kupperman Index>20 significantly reduced sleep symptoms; two trials had significant reductions for pain: isoflavone powder (90 mg) and red clover (80 mg). The only trial in this systematic review that significantly reduced cognitive symptoms was red clover (80 mg). In one trial, red clover isoflavone (80 mg/day) significantly relieved hot flashes, mood, pain, and cognitive symptoms. Amino acids yielded no significant results. Equol supplements of 30 mg/day for non-Equol producing women significantly reduced mood symptoms in one trial. The magnolia bark extract combination significantly reduced hot flashes, mood, and sleep symptoms. CONCLUSIONS Isoflavone trials yielded significant reductions on hot flashes and co-occurring symptoms during the menopausal transition and postmenopause, but studies require replication with larger sample sizes and attention to measurement of outcomes.

Abstract
OBJECTIVE The relatively modest benefit of vasomotor symptom relief in clinical trials of isoflavones may reflect once-daily dosing and low percentages of participants who are able to metabolize daidzein into equol, a potentially more biologically active isoflavone. This pilot study examined whether symptom reduction was greater with more frequent administration and with higher daily doses. In addition, we explored possible effect modification by equol producer status. METHODS We randomized 130 perimenopausal (no menses in the past 3 mo) and postmenopausal (≥12 mo of amenorrhea) women with a mean of five or more moderate/severe hot flashes per day to treatment arms with varying total daily isoflavone doses and dosing frequency, separately for equol producers and nonproducers. Participants recorded the daily frequency and severity of hot flashes. Analyses compared mean daily hot flash intensity scores (sum of hot flashes weighted by severity) by total daily dose and by dosing frequency. Dose- and frequency-related differences were also compared for equol producers and nonproducers. RESULTS Hot flash intensity scores were lowest in women randomized to the highest total daily dose (100-200 mg) and in women randomized to the highest dosing frequency (twice daily to thrice daily), with greater benefits on nighttime scores than on daytime scores. Dose- and frequency-related differences were somewhat larger in equol producers than in nonproducers. CONCLUSIONS These results suggest that a twice-daily to thrice-daily dosing frequency may improve the benefit of isoflavones for vasomotor symptom relief, particularly in equol producers and for nighttime symptoms. Larger studies are needed to confirm these findings.

Abstract
The term red face is reserved for lesions located exclusively or very predominantly on the face that result from changes in cutaneous blood flow triggered by multiple different conditions. Facial erythema may not only present clinically as a distinct entity, but can also be a sign of other diseases. Patients with a red face challenge clinicians to consider a broad differential diagnosis. Diagnosis is based on date and mode of appearance, characteristics of the erythema, functional signs, and associated systemic manifestations. In most cases, the cause is a benign disease such as rosacea, contact dermatitis, photodermatosis, and climacterium, and a thorough history and physical examination is enough to make a diagnosis; facial erythema may also present as a symptom of drug allergies, cardiac disease, carcinoid syndrome, pheochromocytoma, mastocytosis, and anaphylaxis, as well as some rare causes such as medullary carcinoma of the thyroid, pancreatic cell tumor, and renal carcinoma where further laboratory, radiologic, or histopathologic studies are required. In this review, the mechanisms of flushing, its clinical differential diagnosis, and management of various conditions that cause flushing are discussed.

Abstract
OBJECTIVE This study aims to evaluate the effects of soy isoflavones on breast tissue in postmenopausal women. METHODS In this randomized, double-blind, placebo-controlled study, 80 women (aged ≥ 45 y and with amenorrhea >12 mo) with vasomotor symptoms were randomized to receive either 250 mg of standardized soy extract corresponding to isoflavone 100 mg/day (n = 40) or placebo (n = 40) for 10 months. Breasts were evaluated through mammographic density and breast parenchyma using ultrasound (US) at baseline and 10-month follow-up. Independent t test, analysis of variance, Mann-Whitney U test, and χ2 trend test were used in statistical analysis. RESULTS Baseline clinical characteristics showed no significant differences between the isoflavone group and the placebo group, with mean (SD) age of 55.1 (6.0) and 56.2 (7.7) years, mean (SD) menopause duration of 6.6 (4.8) and 7.1 (4.2) years, and mean (SD) body mass index of 29.7 (5.0) and 28.5 (4.9) kg/m2, respectively (P > 0.05). The study was completed by 32 women on isoflavone and 34 women on placebo. The groups did not differ in mammographic density or breast parenchyma by US (P > 0.05). Within each group, the baseline and final moments did not differ in mammography or US parameters significantly (P > 0.05). CONCLUSIONS The use of soy isoflavone extract for 10 months does not affect breast density, as assessed by mammography and US, in postmenopausal women.

Abstract
Stellate ganglion block (SGB) has been used for over 70 years to treat various cervical pain syndromes. Over the past 8 years, 4 different groups have reported on SGB's effects on hot flashes from unblinded, open-label trials. Review of these studies has shown markedly disparate results in terms of the magnitude of hot flash reduction from Baseline with one trial showing a 90% reduction in hot flashes and 3 other trials showing 28-44% reductions in hot flashes. The inconsistencies in these results in addition to the known potentially large (>50%) placebo effects that can occur in randomized controlled hot flash clinical trials make it difficult to render any conclusions regarding the efficacy of SGB for hot flashes at this time. A randomized controlled trial, including a sham saline treatment arm, needs to be performed to properly assess SGB's effects on hot flashes, Methodological challenges with such a study design are addressed and several suggestions are proposed to manage these challenges.
