RESUMEN

BACKGROUND: Oxaliplatin is a key chemotherapeutic agent in the treatment of local and metastatic gastrointestinal (GI) malignancies. Dose density and treatment adherence can be limited by chemotherapy-induced peripheral neuropathy (CIPN). Early research suggests CIPN incidence and severity may be mitigated by acupuncture, but rigorous data in GI oncology patients is limited. Here, we describe the protocol of a randomized, waitlist-controlled pilot study testing the use of preemptive of acupuncture plus acupressure to decrease CIPN and chemotherapy-related toxicities. METHODS: Patients with a GI malignancy (n = 56) with planned 5-fluorouracil (5-FU) and oxaliplatin IV (FOLFOX, FOLFIRINOX) every 2 weeks are being recruited. Additional concurrent anti-neoplastic agents may be used. Enrolled patients are randomized 1:1 to a 3-month intervention of Arm A: acupuncture with acupressure and standard-of-care treatment, or Arm B: standard-of-care alone. In Arm A, on days 1 and 3 of each chemotherapy cycle a standardized acupuncture protocol is administered and patients are taught self-acupressure to perform daily between chemotherapy treatments. Patients in both arms are given standard-of-care oral and peripheral (hands/feet) ice chip cryotherapy during oxaliplatin administration. CIPN and other symptoms are assessed at baseline, 6 weeks, and 3 months from registration. The primary endpoint is CIPN severity at 3 months (EORTC-CIPN 20). Additional endpoints evaluate CIPN incidence (CTCAE, Neuropen, tuning fork); incidence of pain, fatigue, nausea, oral dysesthesia, and anxiety; and feasibility (recruitment, retention, adherence, acceptability). If warranted, trial results will inform the design of a multi-center trial to expand testing of the intervention to a larger patient cohort.

RESUMEN

PURPOSE: To assess whether higher plasma 25-hydroxyvitamin D [25(OH)D] is associated with improved outcomes in colon cancer and whether circulating inflammatory cytokines mediate such association. EXPERIMENTAL DESIGN: Plasma samples were collected from 1,437 patients with stage III colon cancer enrolled in a phase III randomized clinical trial (CALGB/SWOG 80702) from 2010 to 2015, who were followed until 2020. Cox regressions were used to examine associations between plasma 25(OH)D and disease-free survival (DFS), overall survival (OS), and time to recurrence (TTR). Mediation analysis was performed for circulating inflammatory biomarkers of C-reactive protein (CRP), IL6, and soluble TNF receptor 2 (sTNF-R2). RESULTS: Vitamin D deficiency [25(OH)D <12 ng/mL] was present in 13% of total patients at baseline and in 32% of Black patients. Compared with deficiency, nondeficient vitamin D status (≥12 ng/mL) was significantly associated with improved DFS, OS, and TTR (all Plog-rank<0.05), with multivariable-adjusted HRs of 0.68 (95% confidence interval, 0.51-0.92) for DFS, 0.57 (0.40-0.80) for OS, and 0.71 (0.52-0.98) for TTR. A U-shaped dose-response pattern was observed for DFS and OS (both Pnonlinearity<0.05). The proportion of the association with survival that was mediated by sTNF-R2 was 10.6% (Pmediation = 0.04) for DFS and 11.8% (Pmediation = 0.05) for OS, whereas CRP and IL6 were not shown to be mediators. Plasma 25(OH)D was not associated with the occurrence of ≥ grade 2 adverse events. CONCLUSIONS: Nondeficient vitamin D is associated with improved outcomes in patients with stage III colon cancer, largely independent of circulation inflammations. A randomized trial is warranted to elucidate whether adjuvant vitamin D supplementation improves patient outcomes.

RESUMEN

Importance: Clinical outcomes after curative treatment of resectable pancreatic ductal adenocarcinoma (PDA) remain suboptimal. To assess the potential of early control of systemic disease with multiagent perioperative chemotherapy, we conducted a prospective trial. Objective: To determine 2-year overall survival (OS) using perioperative chemotherapy for resectable PDA. Design, Setting, and Participants: This was a randomized phase 2 trial of perioperative chemotherapy with a pick-the-winner design. It was conducted across the National Clinical Trials Network, including academic and community centers all across the US. Eligibility required patients with Zubrod Performance Score of 0 or 1, confirmed tissue diagnosis of PDA, and resectable disease per Intergroup criteria. Interventions: Perioperative (12 weeks preoperative, 12 weeks postoperative) chemotherapy with either fluorouracil, irinotecan, and oxaliplatin (mFOLFIRINOX, arm 1) or gemcitabine/nab-paclitaxel (arm 2). Main Outcomes and Measures: The primary outcome was 2-year overall survival (OS), using a pick-the-winner design; for 100 eligible patients, accrual up to 150 patients was planned to account for cases deemed ineligible at central radiology review. Results: From 2015 to 2018, 147 patients were enrolled; 43 patients (29%) had ineligible disease, beyond resectability criteria, at central radiology review. There were 102 eligible and evaluable patients, 55 in arm 1 and 47 in arm 2, of whom the median (range) age was 66 (44-76) and 64 (46-76) years, respectively; 36 patients (65%) in arm 1 and 24 (51%) in arm 2 were men. In arm 1, 34 (62%) had Zubrod Performance Score of 0, while in arm 2, 31 (66%) did; and 44 (80%) in arm 1 and 39 (83%) in arm 2 had head tumors. Of 102 patients, 84% and 85% completed preoperative chemotherapy, 73% and 70% underwent resection, and 49% and 40% completed all treatment. Adverse events were expected hematologic toxic effects, fatigue, and gastrointestinal toxicities. Two-year OS was 47% (95% CI, 31%-61%) for arm 1 and 48% (95% CI, 31%-63%) for arm 2; median OS was 23.2 months (95% CI, 17.6-45.9 months) and 23.6 months (95% CI, 17.8-31.7 months). Neither arm's 2-year OS estimate was significantly higher than the a priori threshold of 40%. Median disease-free survival after resection was 10.9 months in arm 1 and 14.2 months in arm 2. Conclusions and Relevance: This phase 2 randomized clinical trial did not demonstrate an improved OS with perioperative chemotherapy, compared with historical data from adjuvant trials in resectable pancreatic cancer. Two-year OS was 47% with mFOLFIRINOX and 48% with gemcitabine/nab-paclitaxel for all eligible patients starting treatment for resectable PDA. The trial also demonstrated adequate safety and high resectability rates with perioperative chemotherapy, and challenges in quality control for resectability criteria.

RESUMEN

OBJECTIVE: To evaluate the relationship between diurnal salivary cortisol patterns and distress from heart palpitations in midlife women. METHODS: We analyzed baseline data from 293 women who were eligible for a 3 × 2 factorial trial of exercise or yoga versus routine activity, and omega-3 fish oil versus placebo for vasomotor symptoms. Women self-collected salivary cortisol using swabs at four time points over 2 consecutive days and reported distress from heart racing or pounding during the past 2 weeks using a single item. Sample description and covariate data included demographics, clinical data, vasomotor symptom frequency from daily diaries, medication use, and validated questionnaires on depression, stress, and insomnia (Patient Health Questionnaire-8, Perceived Stress Scale, and Insomnia Severity index). Data were analyzed using descriptive statistics, chi-square and t tests, and repeated measure linear regression models. RESULTS: Participants were on average 54.6 (SD = 3.6) years old, most were White (67%) postmenopausal (84%), and 26% reported distress related to palpitations. In adjusted models, the morning (wake plus 30-min) geometric mean daily salivary cortisol concentrations were significantly more blunted in those with distress from palpitations compared with those without distress (P ≤ 0.03). When all covariates were controlled, distress from palpitations was the sole significant predictor of wake plus 30-minute cortisol (-0.25 [-0.45 to -0.04], P = 0.02). CONCLUSIONS: Palpitations among midlife women may be associated with blunted morning cortisol, and this relationship is not explained by demographics, clinical variables, vasomotor symptoms, medications, depression, stress, or insomnia.

RESUMEN

OBJECTIVE: The optimal neoadjuvant therapy for resectable pancreatic ductal adenocarcinoma (PDA) and the impact on surgical outcomes remains unclear. METHODS: S1505 (NCT02562716) was a randomized phase II study of perioperative chemotherapy with mFOLFIRINOX (Arm 1) or gemcitabine/nab-paclitaxel (Arm 2). Measured parameters included resection rate, margin positivity, pathologic response, and toxicity. RESULTS: Between 2015 and 2018, 147 patients were randomized. Of these, 44 (30%) were deemed ineligible (43 by central review). Of the 103 eligible patients, 77 (76%) completed preoperative therapy and underwent surgery; reasons patients did not undergo surgery included toxicity related to preoperative therapy (n = 9), progression (n = 9), or other (n = 7). Of the 77, 73 (95%) underwent successful resection; 21 (29%) required vascular reconstruction, 62 (85%) had negative (R0) margins, and 24 (33%) had a complete or major pathologic response to therapy. The grade 3-5 postoperative complication rate was 16%. Of the 73 patients completing surgery, 57 (78%) started and 46 (63%) completed postoperative therapy. This study represents the first prospective trial evaluating modern systemic therapy delivered in a neoadjuvant/perioperative format for resectable PDA. CONCLUSIONS: We have demonstrated: (1) Based on the high percentage of enrolled, but ineligible patients, it is clear that adherence to strict definitions of resectable PDA is challenging; (2) Patients can tolerate modern systemic therapy and undergo successful surgical resection without prohibitive perioperative complications; (3) Completion of adjuvant therapy in the perioperative format is difficult; (4) Major pathologic response rate of 33% is encouraging.

RESUMEN

OBJECTIVE: The Menopause Strategies: Finding Lasting Answers for Symptoms and Health network conducted three randomized clinical trials (RCTs) testing six interventions treating vasomotor symptoms (VMS), and also collected menopause-related quality of life (QOL) measures. A fourth RCT assessed an intervention for insomnia symptoms among women with VMS. We describe these seven interventions' effects on menopause-related QOL relative to control in women with VMS. METHODS: We pooled individual-level data from 1,005 peri- and postmenopausal women with 14 or more VMS/week across the four RCTs. Interventions included escitalopram 10 to 20 mg/d; yoga/aerobic exercise; 1.8 g/d omega-3-fatty acids; oral 17-beta-estradiol 0.5 mg/d; venlafaxine XR 75 mg/d; and cognitive behavioral therapy for insomnia (CBT-I). Outcomes measures were the Menopause-specific Quality of Life scale and its subscales. RESULTS: Significant improvements in total Menopause-specific Quality of Life from baseline were observed with estradiol, escitalopram, CBT-I, and yoga, with mean decreases of 0.3 to 0.5 points relative to control. The largest improvement in the vasomotor subscale was observed with estradiol (-1.2 points), with more modest but significant effects seen with escitalopram, yoga, and CBT-I. Significant improvements in the psychosocial subscale were observed for escitalopram, venlafaxine, and CBT-I. For the physical subscale, the greatest improvement was observed for CBT-I and exercise, whereas for the sexual subscale, the greatest improvement was observed for CBT-I, with yoga and estradiol demonstrating smaller effects. CONCLUSIONS: These results suggest that for menopause-related QOL, women have a variety of treatment strategies to choose from and can select an approach based on most bothersome symptoms and individual preferences.

RESUMEN

Study Objectives: The Menopause Strategies: Finding Lasting Answers for Symptoms and Health network conducted three randomized clinical trials (RCTs) testing six interventions treating vasomotor symptoms (VMS), and also collected self-reported sleep outcomes. A fourth RCT assessed an intervention for insomnia symptoms among women with VMS. We describe these seven interventions' effects relative to control in women with comparably severe insomnia symptoms and VMS. Methods: We analyzed pooled individual-level data from 546 peri- and postmenopausal women with Insomnia Severity Index (ISI) ≥ 12, and ≥14 bothersome VMS/week across the four RCTs. Interventions included the following: escitalopram 10-20 mg/day; yoga; aerobic exercise; 1.8 g/day omega-3 fatty acids; oral 17-beta-estradiol 0.5-mg/day; venlafaxine XR 75-mg/day; and cognitive behavioral therapy for insomnia (CBT-I). Outcome measures were ISI and Pittsburgh Sleep Quality Index (PSQI) over 8-12 weeks of treatment. Results: CBT-I produced the greatest reduction in ISI from baseline relative to control at -5.2 points (95% CI -7.0 to -3.4). Effects on ISI were similar for exercise at -2.1 and venlafaxine at -2.3 points. Comparably small decreases in ISI were observed with escitalopram, yoga, and estradiol. The largest reduction in PSQI from baseline was with CBT-I at -2.7 points (-3.9 to -1.5), although PSQI decreases of 1.2 to 1.6 points were significantly better than control with escitalopram, exercise, yoga, estradiol, and venlafaxine. Omega-3 supplements did not improve insomnia symptoms. Conclusions: This study's findings support current recommendations for CBT-I as a first line treatment in healthy midlife women with insomnia symptoms and moderately bothersome VMS.

RESUMEN

STUDY OBJECTIVES: To determine effects of yoga and aerobic exercise compared with usual activity on objective assessments of sleep in midlife women. METHODS: Secondary analyses of a randomized controlled trial in the Menopause Strategies: Finding Lasting Answers for Symptoms and Health (MsFLASH) network conducted among 186 late transition and postmenopausal women aged 40-62 y with hot flashes. Women were randomized to 12 w of yoga, supervised aerobic exercise, or usual activity. The mean and coefficient of variation (CV) of change in actigraph sleep measures from each intervention group were compared to the usual activity group using linear regression models. RESULTS: Baseline values of the primary sleep measures for the entire sample were mean total sleep time (TST) = 407.5 ± 56.7 min; mean wake after sleep onset (WASO) = 54.6 ± 21.8 min; mean CV for WASO = 37.7 ± 18.7 and mean CV for number of long awakenings > 5 min = 81.5 ± 46.9. Changes in the actigraphic sleep outcomes from baseline to weeks 11-12 were small, and none differed between groups. In an exploratory analysis, women with baseline Pittsburgh Sleep Quality Index higher than 8 had significantly reduced TST-CV following yoga compared with usual activity. CONCLUSIONS: This study adds to the currently scant literature on objective sleep outcomes from yoga and aerobic exercise interventions for this population. Although small effects on self-reported sleep quality were previously reported, the interventions had no statistically significant effects on actigraph measures, except for potentially improved sleep stability with yoga in women with poor self-reported sleep quality.

RESUMEN

OBJECTIVES: Heart rate variability (HRV) reflects the integration of the parasympathetic nervous system with the rest of the body. Studies on the effects of yoga and exercise on HRV have been mixed but suggest that exercise increases HRV. We conducted a secondary analysis of the effect of yoga and exercise on HRV based on a randomized clinical trial of treatments for vasomotor symptoms in peri/post-menopausal women. DESIGN: Randomized clinical trial of behavioral interventions in women with vasomotor symptoms (n=335), 40-62 years old from three clinical study sites. INTERVENTIONS: 12-weeks of a yoga program, designed specifically for mid-life women, or a supervised aerobic exercise-training program with specific intensity and energy expenditure goals, compared to a usual activity group. MAIN OUTCOME MEASURES: Time and frequency domain HRV measured at baseline and at 12 weeks for 15min using Holter monitors. RESULTS: Women had a median of 7.6 vasomotor symptoms per 24h. Time and frequency domain HRV measures did not change significantly in either of the intervention groups compared to the change in the usual activity group. HRV results did not differ when the analyses were restricted to post-menopausal women. CONCLUSIONS: Although yoga and exercise have been shown to increase parasympathetic-mediated HRV in other populations, neither intervention increased HRV in middle-aged women with vasomotor symptoms. Mixed results in previous research may be due to sample differences. Yoga and exercise likely improve short-term health in middle-aged women through mechanisms other than HRV.

RESUMEN

OBJECTIVE: To describe the effects of six interventions for menopausal vasomotor symptoms relative to control in a pooled analysis, facilitating translation of the results for clinicians and symptomatic women. The Menopause Strategies: Finding Lasting Answers for Symptoms and Health network tested these interventions in three randomized clinical trials. METHODS: An analysis of pooled individual-level data from three randomized clinical trials is presented. Participants were 899 perimenopausal and postmenopausal women with at least 14 bothersome vasomotor symptoms per week. Interventions included 10-20 mg escitalopram per day, nonaerobic yoga, aerobic exercise, 1.8 g per day omega-3 fatty acid supplementation, 0.5 mg low-dose oral 17-beta-estradiol (E2) per day, and 75 mg low-dose venlafaxine XR per day. The main outcome measures were changes from baseline in mean daily vasomotor symptom frequency and bother during 8-12 weeks of treatment. Linear regression models estimated differences in outcomes between each intervention and corresponding control group adjusted for baseline characteristics. Models included trial-specific intercepts, effects of the baseline outcome measure, and time. RESULTS: The 8-week reduction in vasomotor symptom frequency from baseline relative to placebo was similar for escitalopram at -1.4 per day (95% confidence interval [CI] -2.7 to -0.2), low-dose E2 at -2.4 (95% CI -3.4 to -1.3), and venlafaxine at -1.8 (95% CI -2.8 to -0.8); vasomotor symptom bother reduction was minimal and did not vary across these three pharmacologic interventions (mean -0.2 to -0.3 relative to placebo). No effects on vasomotor symptom frequency or bother were seen with aerobic exercise, yoga, or omega-3 supplements. CONCLUSION: These analyses suggest that escitalopram, low-dose E2, and venlafaxine provide comparable, modest reductions in vasomotor symptom frequency and bother among women with moderate hot flushes.

RESUMEN

PURPOSE: The role of postoperative therapy in extrahepatic cholangiocarcinoma (EHCC) or gallbladder carcinoma (GBCA) is unknown. S0809 was designed to estimate 2-year survival (overall and after R0 or R1 resection), pattern of relapse, and toxicity in patients treated with this adjuvant regimen. PATIENTS AND METHODS: Eligibility criteria included diagnosis of EHCC or GBCA after radical resection, stage pT2-4 or N+ or positive resection margins, M0, and performance status 0 to 1. Patients received four cycles of gemcitabine (1,000 mg/m(2) intravenously on days 1 and 8) and capecitabine (1,500 mg/m(2) per day on days 1 to 14) every 21 days followed by concurrent capecitabine (1,330 mg/m(2) per day) and radiotherapy (45 Gy to regional lymphatics; 54 to 59.4 Gy to tumor bed). With 80 evaluable patients, results would be promising if 2-year survival 95% CI were > 45% and R0 and R1 survival estimates were ≥ 65% and 45%, respectively. RESULTS: A total of 79 eligible patients (R0, n = 54; R1, n = 25; EHCC, 68%; GBCA, 32%) were treated (86% completed). For all patients, 2-year survival was 65% (95% CI, 53% to 74%); it was 67% and 60% in R0 and R1 patients, respectively. Median overall survival was 35 months (R0, 34 months; R1, 35 months). Local, distant, and combined relapse occurred in 14, 24, and nine patients. Grade 3 and 4 adverse effects were observed in 52% and 11% of patients, respectively. The most common grade 3 to 4 adverse effects were neutropenia (44%), hand-foot syndrome (11%), diarrhea (8%), lymphopenia (8%), and leukopenia (6%). There was one death resulting from GI hemorrhage. CONCLUSION: This combination was well tolerated, has promising efficacy, and provides clinicians with a well-supported regimen. Our trial establishes the feasibility of conducting national adjuvant trials in EHCC and GBCA and provides baseline data for planning future phase III trials.

RESUMEN

OBJECTIVE: This report describes the Menopausal Strategies: Finding Lasting Answers to Symptoms and Health network and methodological issues addressed in designing and implementing vasomotor symptom trials. METHODS: Established in response to a National Institutes of Health request for applications, the network was charged with conducting rapid throughput randomized trials of novel and understudied available interventions postulated to alleviate vasomotor and other menopausal symptoms. Included are descriptions of and rationale for criteria used for interventions and study selection, common eligibility and exclusion criteria, common primary and secondary outcome measures, consideration of placebo response, establishment of a biorepository, trial duration, screening and recruitment, statistical methods, and quality control. All trial designs are presented, including the following: (1) a randomized, double-blind, placebo-controlled clinical trial designed to evaluate the effectiveness of the selective serotonin reuptake inhibitor escitalopram in reducing vasomotor symptom frequency and severity; (2) a two-by-three factorial design trial to test three different interventions (yoga, exercise, and ω-3 supplementation) for the improvement of vasomotor symptom frequency and bother; and (3) a three-arm comparative efficacy trial of the serotonin-norepinephrine reuptake inhibitor venlafaxine and low-dose oral estradiol versus placebo for reducing vasomotor symptom frequency. The network's structure and governance are also discussed. CONCLUSIONS: The methods used in and the lessons learned from the Menopausal Strategies: Finding Lasting Answers to Symptoms and Health trials are shared to encourage and support the conduct of similar trials and to encourage collaborations with other researchers.

OBJECTIVE: This study aims to determine the efficacy and tolerability of omega-3 fatty acids in reducing vasomotor symptoms (VMS) frequency and bother in perimenopausal and postmenopausal women. METHODS: This study was a 12-week, three-by-two factorial, randomized controlled trial. Eligible women were randomized to a double-blind comparison of omega-3 (n = 177) or placebo (n = 178) capsules, and simultaneously to yoga (n = 107), aerobic exercise (n = 106), or their usual physical activity (n = 142). Participants received 1.8 g of omega-3 daily for 12 weeks. Each capsule contained ethyl eicosapentaenoic acid (425 mg), docosahexaenoic acid (100 mg), and other omega-3s (90 mg). Primary outcomes were VMS frequency and bother. Secondary outcomes included sleep quality (Pittsburgh Sleep Quality Index), insomnia symptoms (Insomnia Severity Index), depressive symptoms (Physician's Health Questionnaire-8), and anxiety (Generalized Anxiety Disorder-7). RESULTS: The mean baseline frequency of VMS per day was 7.6 (95% CI, 7.0 to 8.2). After 12 weeks, the reduction in VMS frequency with omega-3 (-2.5; 95% CI, -3.0 to -1.9) did not differ significantly from that with placebo (-2.7; 95% CI, -3.3 to -2.2), with a relative difference of 0.3 fewer hot flashes per day (95% CI, -0.5 to 1.0; P = 0.28). Changes in VMS bother at 12 weeks were also similar between groups, with no relative difference on a four-point scale (95% CI, -0.1 to 0.2; P = 0.36). Omega-3s compared with placebo showed no improvement in self-reported sleep or mood (P > 0.09 for all comparisons). CONCLUSIONS: Among healthy, sedentary perimenopausal and postmenopausal women, a 12-week treatment with omega-3 does not improve VMS frequency, VMS bother, sleep, or mood compared with placebo.

RESUMEN

OBJECTIVE: This study aims to determine the efficacy of yoga in alleviating vasomotor symptoms (VMS) frequency and bother. METHODS: This study was a three-by-two factorial, randomized controlled trial. Eligible women were randomized to yoga (n = 107), exercise (n = 106), or usual activity (n = 142), and were simultaneously randomized to a double-blind comparison of ω-3 fatty acid (n = 177) or placebo (n = 178) capsules. Yoga intervention consisted of 12 weekly 90-minute yoga classes with daily home practice. Primary outcomes were VMS frequency and bother assessed by daily diaries at baseline, 6 weeks, and 12 weeks. Secondary outcomes included insomnia symptoms (Insomnia Severity Index) at baseline and 12 weeks. RESULTS: Among 249 randomized women, 237 (95%) completed 12-week assessments. The mean baseline VMS frequency was 7.4 per day (95% CI, 6.6 to 8.1) in the yoga group and 8.0 per day (95% CI, 7.3 to 8.7) in the usual activity group. Intent-to-treat analyses included all participants with response data (n = 237). There was no difference between intervention groups in the change in VMS frequency from baseline to 6 and 12 weeks (mean difference [yoga--usual activity] from baseline at 6 wk, -0.3 [95% CI, -1.1 to 0.5]; mean difference [yoga--usual activity] from baseline at 12 wk, -0.3 [95% CI, -1.2 to 0.6]; P = 0.119 across both time points). Results were similar for VMS bother. At week 12, yoga was associated with an improvement in insomnia symptoms (mean difference [yoga - usual activity] in the change in Insomnia Severity Index, 1.3 [95% CI, -2.5 to -0.1]; P = 0.007). CONCLUSIONS: Among healthy women, 12 weeks of yoga class plus home practice, compared with usual activity, do not improve VMS frequency or bother but reduce insomnia symptoms.

RESUMEN

OBJECTIVE: The purpose of this study was to determine the efficacy of 3 nonhormonal therapies for the improvement of menopause-related quality of life in women with vasomotor symptoms. STUDY DESIGN: We conducted a 12-week 3 × 2 randomized, controlled, factorial design trial. Peri- and postmenopausal women, 40-62 years old, were assigned randomly to yoga (n = 107), exercise (n = 106), or usual activity (n = 142) and also assigned randomly to a double-blind comparison of omega-3 (n = 177) or placebo (n = 178) capsules. We performed the following interventions: (1) weekly 90-minute yoga classes with daily at-home practice, (2) individualized facility-based aerobic exercise training 3 times/week, and (3) 0.615 g omega-3 supplement, 3 times/day. The outcomes were assessed with the following scores: Menopausal Quality of Life Questionnaire (MENQOL) total and domain (vasomotor symptoms, psychosocial, physical and sexual). RESULTS: Among 355 randomly assigned women who average age was 54.7 years, 338 women (95%) completed 12-week assessments. Mean baseline vasomotor symptoms frequency was 7.6/day, and the mean baseline total MENQOL score was 3.8 (range, 1-8 from better to worse) with no between-group differences. For yoga compared to usual activity, baseline to 12-week improvements were seen for MENQOL total -0.3 (95% confidence interval, -0.6 to 0; P = .02), vasomotor symptom domain (P = .02), and sexuality domain (P = .03) scores. For women who underwent exercise and omega-3 therapy compared with control subjects, improvements in baseline to 12-week total MENQOL scores were not observed. Exercise showed benefit in the MENQOL physical domain score at 12 weeks (P = .02). CONCLUSION: All women become menopausal, and many of them seek medical advice on ways to improve quality of life; little evidence-based information exists. We found that, among healthy sedentary menopausal women, yoga appears to improve menopausal quality of life; the clinical significance of our finding is uncertain because of the modest effect.

RESUMEN

BACKGROUND: Behavioral strategies are recommended for menopausal symptoms, but little evidence exists regarding efficacy. PURPOSE: Describe design and methodology of a randomized controlled 3 by 2 factorial trial of yoga, exercise and omega-3 fatty acids. METHODS: Women from three geographic areas with a weekly average of ≥14 hot flashes/night sweats, who met exclusion/inclusion criteria, were randomized to 12weeks of: 1) yoga classes and daily home practice; 2) supervised, facility-based aerobic exercise training; or 3) usual activity. Women in each arm were further randomized to either omega-3 supplement or placebo. Standardized training, on-going monitoring, and site visits were adopted to ensure consistency across sites and fidelity to the intervention. Participant adherence to the intervention protocol was monitored continuously, and retention was actively encouraged by staff. Information on adverse events was systematically collected. RESULTS: Of 7377 women who responded to mass mailings, 355 (4.8%) were randomized; mean age was 54.7 (sd=3.7), 26.2% were African American, 81.7% were post-menopausal, and mean baseline frequency of daily hot flashes/night sweats was 7.6 (sd=3.8). Adherence of ≥80% was 59% for yoga, 77% for exercise training, and 80% for study pills. Final week 12 data were collected from 95.2% CONCLUSIONS: Conducting a multi-site, multi-behavioral randomized trial for menopausal symptoms is challenging but feasible. Benefits included cost-effective study design, centralized recruitment, and methodologic standardization.
