Randomized trial of Tibetan yoga in patients with breast cancer undergoing chemotherapy.

BACKGROUND: The current randomized trial examined the effects of a Tibetan yoga program (TYP) versus a stretching program (STP) and usual care (UC) on sleep and fatigue in women with breast cancer who were undergoing chemotherapy. METHODS: Women with stage (American Joint Committee on Cancer (AJCC) TNM) I to III breast cancer who were undergoing chemotherapy were randomized to TYP (74 women), STP (68 women), or UC (85 women). Participants in the TYP and STP groups participated in 4 sessions during chemotherapy, followed by 3 booster sessions over the subsequent 6 months, and were encouraged to practice at home. Self-report measures of sleep disturbances (Pittsburgh Sleep Quality Index), fatigue (Brief Fatigue Inventory), and actigraphy were collected at baseline; 1 week after treatment; and at 3, 6, and 12 months. RESULTS: There were no group differences noted in total sleep disturbances or fatigue levels over time. However, patients in the TYP group reported fewer daily disturbances 1 week after treatment compared with those in the STP (difference, -0.43; 95% confidence interval [95% CI], -0.82 to -0.04 [P = .03]) and UC (difference, -0.41; 95% CI, -0.77 to -0.05 [P = .02]) groups. Group differences at the other time points were maintained for TYP versus STP. Actigraphy data revealed greater minutes awake after sleep onset for patients in the STP group 1 week after treatment versus those in the TYP (difference, 15.36; 95% CI, 7.25-23.48 [P = .0003]) and UC (difference, 14.48; 95% CI, 7.09-21.87 [P = .0002]) groups. Patients in the TYP group who practiced at least 2 times a week during follow-up reported better Pittsburgh Sleep Quality Index and actigraphy outcomes at 3 months and 6 months after treatment compared with those who did not and better outcomes compared with those in the UC group. CONCLUSIONS: Participating in TYP during chemotherapy resulted in modest short-term benefits in sleep quality, with long-term benefits emerging over time for those who practiced TYP at least 2 times a week.

Effects of the Brief Simha Kriya Breathing Practice for Health Care Workers During the COVID-19 Pandemic.

Introduction: During the COVID-19 pandemic, health care workers (HCWs) experienced increased anxiety, depression, loneliness, and other mental health issues. HCWs need additional resources to cope with the mental health impact of their work. Yoga techniques could be helpful strategies to manage different stressors during times of uncertainty. Methods: This prospective, single-arm, trial examined the effects of a brief pranayama yoga practice on the wellbeing of HCWs during the height of COVID-19. HCWs were recruited through announcements and institutional websites at a large major cancer center in the southern United States. A short, prerecorded, 5-min breathwork video intervention called "Simha Kriya" was provided to participants, and they were encouraged to practice one to two times daily for 4 weeks. Participants completed self-report instruments at baseline and weeks 1 and 4, including: (1) Perceived Stress Scale (PSS); (2) Brief Resilient Coping Scale (BRCS); and (3) a questionnaire assessing the experience of COVID-19 among HCWs that had five subscales. HCWs also conducted a measure of breath holding time. Paired sample t-tests and mixed-effects analysis of variance models examined changes over time. Results: One hundred participants consented to the study, with 88 female, 60 white, 39 worked remotely, and 27 were clinical staff. Sixty-nine participants provided data at week 1 and 56 at week 4. Participants' adherence to the breathing exercises between weeks 1 and 4 was similar, with a mean of six times per week. At week 4, there were significant decreases in the COVID-19 Distress score (p < 0.0001) and COVID-19 Disruption (p = 0.013), yet no changes in the PSS. There were also significant increases in COVID-19 Stress Management (p = 0.0001) and BRCS scores (p = 0.012), but no changes in Perceived Benefits of COVID-19 and no changes in breath holding time. Discussion: Brief yoga-based breathing practices helped reduce pandemic-specific stress, improved resilience, and stress management skills in HCWs. Trial Registration Number: NCT04482647.

Dietary Magnesium Replacement for Prevention of Hypomagnesemia in Patients With Ovarian Cancer Receiving Carboplatin-Based Chemotherapy.

PURPOSE: Hypomagnesemia is a common side effect of platinum-based chemotherapy and predicts poor overall survival in some cancers. Standard magnesium replacement strategies are often inadequate for maintaining magnesium levels. We hypothesized that a daily dietary magnesium replacement approach through magnesium-rich foods would help maintain adequate magnesium levels during platinum-based treatment. MATERIALS AND METHODS: We conducted a prospective feasibility study of magnesium-rich diets in patients 18 years and older with previously untreated ovarian cancer scheduled to receive carboplatin-containing chemotherapy of at least six consecutive cycles. Education about magnesium-rich diets was provided at enrollment and then weekly during chemotherapy. Feasibility was defined as ≥60% completion of dietary recalls and ≥280 mg average daily dietary magnesium intake across all patients. RESULTS: Twenty-one of 26 patients enrolled completed at least five chemotherapy cycles and were included in the analysis. Adherence to the study diet was 76%. Daily dietary magnesium intake was 100.5 mg at baseline and increased throughout each cycle: 6% of patients at baseline, 24% after the first cycle, and 67% after the fifth cycle reached ≥280-mg/day magnesium intake. Seven (33%) of 21 had at least one incident of hypomagnesemia. Patients who were adherent had significantly lower incidence of hypomagnesemia (19% v 80%, P = .03) and less need for intravenous magnesium (6% v 60%, P = .03) than those who were nonadherent. CONCLUSION: The study achieved primary feasibility objectives of retention and adherence to the study intervention. Weekly education about magnesium-rich diets was effective in increasing dietary magnesium intake. Adequate dietary magnesium appeared to be protective against hypomagnesemia.

A Pragmatic Evaluation of Symptom Distress After Group Meditation for Cancer Patients and Caregivers: A Preliminary Report.

CONTEXT: Complementary health approaches such as meditation may help improve cancer patient and caregiver symptoms, yet little research has examined the clinical application of these programs. OBJECTIVES: We explored the effects of a meditation group class, offered as part of an integrative medicine clinic at a comprehensive cancer center, on patient and caregiver self-reported symptoms. METHODS: Participants (patients and caregivers) of any three meditation group classes offered-Power of Breath (PB), Sacred Sounds (SS), and Movement & Breath (MB)-were asked to complete the Edmonton Symptom Assessment Scale (ESAS; scale 0-10, 10 most severe) before and after participation. ESAS individual items and subscales were analyzed; distress subscales included global (global distress score 0-90), physical (physical distress score 0-60), and psychological (psychological distress score, 0-20). Data were analyzed examining premeditation/postmeditation scores using paired t-tests and between types of meditation using analyses of variance. RESULTS: One hundred forty-two unique participants (76 patients and 66 caregivers) attended one or more meditation groups (mean 1.84) from May to December 2015 (265 total attendance: PB n = 92; SS n = 87; MB n = 86). For all participants, we observed clinically significant reduction/improvement in global distress scores (-5.17, SD 8; P < 0.0001) and in individual symptoms (ESAS decrease ≥ 1; means) of well-being (-1.36 SD 1.7; P < 0.0001), fatigue (-1.34 SD 1.9; P < 0.0001), anxiety (-1.26 SD 1.6; P < 0.001), and shortness of breath (-1.2 SD 2; P = 0.001). Comparing class length (60 vs. 90 minutes), class content (PB vs. SS vs. MB), and participants (caregivers vs. patients), there were no statistically significant differences in symptom score reduction. CONCLUSION: A single meditation group class offered as part of clinical care resulted in relief of multiple self-reported symptoms in both patients and caregivers.

A research protocol for a pilot randomized controlled trial designed to examine the feasibility of a couple-based mind-body intervention for patients with metastatic lung cancer and their partners.

BACKGROUND: Given the generally incurable nature of metastatic non-small cell lung cancer (mNSCLC), patients and their romantic partners are at risk for existential/spiritual distress. Although a handful of dyadic psychosocial interventions for lung cancer patients and their caregivers exist, none of them target spiritual well-being. Informed by the mindfulness-based intervention literature and our pilot work in couples affected by lung cancer, we developed a brief couple-based mind-body (CBMB) intervention. The primary aim of this research protocol is to determine the feasibility of implementing the CBMB intervention versus an active control (AC) or wait list control (WLC) group in patients with mNSCLC and their partners using a randomized controlled trial design. METHODS: Seventy-five patients with mNSCLC receiving treatment and their partners are randomized to the CBMB intervention, an AC or a WLC group. Those in the CBMB intervention and AC groups receive four intervention sessions of 60 min each over 4 weeks and complete weekly homework assignments. The first session is delivered in person, and the remaining sessions are delivered via videoconference. The dyads in the AC group discuss cancer-related and personal growth concerns with the interventionist but are not taught coping skills. Patients and partners in all groups complete baseline assessments of quality of life (QOL) prior to randomization. Follow-up assessments are performed 4 weeks and then again 3 months later. The primary outcome is feasibility (i.e., ≥ 30% of eligible couples consent, ≥ 70% of enrolled couples are retained, and ≥ 50% of all CBMB and AC sessions are attended). We will also perform primarily descriptive analyses of the self-reported outcomes (e.g., spiritual well-being and psychological distress) and explore potential intervention mediators (i.e., compassion, communication, mindfulness, and closeness) to inform a larger, future trial. DISCUSSION: This trial will provide important information regarding the feasibility of a behavioral intervention in a vulnerable yet understudied population using videoconferencing and descriptive data regarding spiritual well-being and other indices of QOL in both mNSCLC patients and their partners. TRIAL REGISTRATION: ClinicalTrials.gov NCT02596490.

Pilot Testing of a Brief Couple-Based Mind-Body Intervention for Patients With Metastatic Non-Small Cell Lung Cancer and Their Partners.

CONTEXT: Given the generally incurable nature of metastatic lung cancer, patients and their spouses/partners are at risk for psychological and spiritual distress. To address this concern, we developed a couple-based mind-body (CBMB) intervention. OBJECTIVES: This formative research aimed at examining the intervention's acceptability and initial efficacy in patients with metastatic lung cancer undergoing treatment and their spouses. METHODS: Intervention content evaluation sessions and an ensuing single-arm trial were conducted. To evaluate intervention content, participants performed intervention exercises and then participated in semistructured interviews and completed written evaluations. In the single-arm trial, four intervention sessions were delivered over two weeks, focusing on cultivating mindfulness, interpersonal connection, gratitude, and purpose. Newly recruited couples completed measures of depressive symptoms, cancer distress, spiritual well-being, and sleep disturbances before and after the intervention. RESULTS: Content evaluations by seven dyads of patients and their partners revealed high acceptability ratings for the CBMB intervention (e.g., all participants would recommend the intervention). Consent and adherence rates (54% and 67%, respectively) were acceptable in the single-arm trial. All patients (n = 7 dyads; 67% male; mean age, 55 years) and partners (33% male; mean age, 59 years) rated the intervention as useful. Paired t-test analyses revealed large effect sizes for reduced sleep disturbances (d = 1.83) and medium effect sizes for cancer-specific distress (d = 0.61) for patients and large effect sizes for depressive symptoms (d = 0.90) for partners. CONCLUSION: Based on these results, the CBMB intervention appears to be acceptable and subjectively useful. In addition, we observed preliminary evidence of quality of life gains in both patients and their partners.
