Effect of Yoga on Sleep Quality and Neuroendocrine Immune Response in Metastatic Breast Cancer Patients

Interventions for insomnia in cancer patients and survivors-a comprehensive systematic review and meta-analysis

BACKGROUND

Considering the persistent nature and higher prevalence of insomnia in cancer patients and survivors compared with the general population, there is a need for effective management strategies. This systematic review and meta-analysis aimed to comprehensively evaluate the available evidence for the efficacy of pharmacological and nonpharmacological interventions for insomnia in adult cancer patients and survivors.

METHODS

Following the PRISMA guidelines, we analyzed data from 61 randomized controlled trials involving 6528 participants. Interventions included pharmacological, physical, and psychological treatments, with a focus on insomnia severity and secondary sleep and non-sleep outcomes. Frequentist and Bayesian analytical strategies were employed for data synthesis and interpretation.

RESULTS

Cognitive-Behavioral Therapy for Insomnia (CBT-I) emerged as the most efficacious intervention for reducing insomnia severity in cancer survivors and further demonstrated significant improvements in fatigue, depressive symptoms, and anxiety. CBT-I showed a large postintervention effect (g = 0.86; 95% confidence interval [CI] = 0.57 to 1.15) and a medium effect at follow-up (g = 0.55; 95% CI = 0.18 to 0.92). Other interventions such as bright white light therapy, sleep medication, melatonin, exercise, mind-body therapies, and mindfulness-based therapies showed benefits, but the evidence for their efficacy was less convincing compared with CBT-I. Brief Behavioral Therapy for Insomnia showed promise as a less burdensome alternative for patients in active cancer treatment.

CONCLUSIONS

CBT-I is supported as a first-line treatment for insomnia in cancer survivors, with significant benefits observed across sleep and non-sleep outcomes. The findings also highlight the potential of less intensive alternatives. The research contributes valuable insights for clinical practice and underscores the need for further exploration into the complexities of sleep disturbances in cancer patients and survivors.

Perspectives and experiences of leisure-time physical activity in adults with stage 4 cancer: a qualitative interpretive-description study

PURPOSE

Leisure-time physical activity (LTPA) can be beneficial for individuals with advanced cancer, but little is known on how to tailor rehabilitation strategies targeting LTPA in cancer care. Our objective was to explore perspectives and experiences of LTPA in people with stage 4 cancer.

MATERIALS AND METHODS

Guided by interpretive-description methodology, our qualitative study consisted of individual, semi-structured interviews with 20 Canadian adults diagnosed with stage 4 cancer. Interviews were transcribed verbatim and analyzed inductively.

RESULTS

The participants' median age was 51.5 (range, 35-73) years. Cancer types included breast (n = 12), lung (n = 4), and other (n = 4). Participants highlighted their experiences of LTPA as diverse and complex, impacted by individual and cancer-related factors. They emphasized being intentional with LTPA through activity planning and modification. LTPA participation was linked to physical well-being, social connections, and meanings of accomplishment and loss. Many participants desired personalized support related to LTPA, that is integrated, interprofessional, and accessible in cancer care.

CONCLUSION

The experiences of LTPA for people with stage 4 cancer are personal and connected to health and psychosocial meanings. Further efforts in rehabilitation are needed to address the challenges faced by people with advanced cancer and optimize safe, meaningful participation in LTPA.IMPLICATIONS FOR REHABILITATIONExperiences of leisure-time physical activity in individuals with stage 4 cancer are personal and linked to health benefits and psychosocial meanings.Activity participation frequently involves consideration of cancer-related symptoms, management of risks, and intentional planning and modification of activities.Trained rehabilitation professionals integrated in cancer care may be well suited to support people with stage 4 cancer through personalized activity recommendations.This research can help inform future clinical, research, and educational efforts in rehabilitation aimed at targeting physical activity in individuals with advanced cancer.

Health benefits of yoga for cancer survivors: An updated systematic review and meta-analysis

Objective

To evaluate the effects of yoga on health-related outcomes [i.e., physical function, mental health, and overall quality of life (QOL)] of cancer survivors via a systematic review and meta-analysis of randomized controlled trials (RCTs) over the past 5 years across cancer types.

Methods

An updated systematic review and meta-analysis was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses. RCTs published from January 1, 2018, to February 23, 2023, were searched in five English databases (PubMed, The Cochrane Library, ISI, PsycINFO, and CINAHL), three Chinese databases (Wan Fang, China National Knowledge Infrastructure, and Chinese Biomedical Literature Database), and three English clinical trials registry platforms (International Clinical Trials Registry Platform, ClinicalTrials.gov, and EU Clinical Trials Register).

Results

A total of 34 RCTs were included in this updated review. Yoga benefited the physical function, mental health, and overall QOL of cancer survivors. The effect size of yoga for most physical and mental health-related outcomes was relatively small, but that for the QOL was generally large. The impact of yoga on the QOL of cancer survivors ranged from moderate to high.

Conclusions

Yoga has health benefits for cancer survivors and could therefore be used as an optional supportive intervention for cancer-related symptom management.

Effect of Yoga Intervention on Inflammatory Biomarkers among Women with Breast Cancer - A Systematic Review

Background

Inflammatory markers play a substantial role in the prognosis of breast cancer (BC). Studies have been conducted, evaluating the effect of yoga intervention (YI) on inflammatory biomarkers among BC cases. This systematic review consolidates the outcome of YI in the cancer microenvironment.

Objective

The objective of the study was to evaluate the effect of YI in the cancer microenvironment among BC women.

Materials and Methods

This review was conducted from May 2021 to December 2021. The inclusion criteria were experimental studies on adult BC cases with isolated YI. Studies conducted among paediatrics, case reports and case series were excluded from the study. Medline (PubMed), Medline (Ovid), Web of Science (WOS), Scopus, CINAHL and Cochrane Central databases were searched. The data were restricted from January 2000 to December 2021 with studies published in English. 'The Cochrane risk of bias assessment tool' was mobilised to evaluate the quality of the included studies.

Results

A total of nine studies met the inclusion criteria and comprised a sample size of 905 BC cases with a mean age of 50.26±8.27 years. Three studies evaluated tumour necrosis factor-alpha (TNF-α) and INTERLEUKIN (IL)-6, where two studies on TNF-α and one on IL-6 favoured the YI group. A study investigated soluble TNF receptor II (TNF-RII) and another on IL-1beta (IL-1β) has shown improved levels post-YI. A downward trend of cortisol levels was noted in four out of five studies. Two studies that examined the C-reactive protein and a study on IL-8 did not show any difference between the YI and the control groups.

Conclusion

This review's findings showed the downregulation of cortisol, markers of inflammation; TNF-α, IL-6, TNF-RII and IL-1β immediately to post-YI. Heterogeneities in terms of YIs, number of days of practice, duration and training received and the grade of BC cases are the concern of this review. However, YI can be considered a supportive therapy for BC.

Meta-analysis of effects of yoga exercise intervention on sleep quality in breast cancer patients

Objective

This study seeks to systematically evaluate and test the effects of yoga exercise intervention programs on sleep quality in breast cancer patients in order to suggest more optimized exercise programs.

Method

Computer searches of the PubMed, Embase, Cochrane Library, Web of Science and CINAHL databases are conducted from the date of their inception to June 8^th, 2022 to collect randomized controlled trials on the effects of yoga exercise intervention on sleep quality in breast cancer patients. Two investigators independently carry out the inclusion and exclusion criteria literature screening, data extraction and methodological quality assessment of the included literature by applying the Cochrane risk of bias tool. Subgroup analysis is performed using RevMan 5.4.1 software, and the six moderating variables of intervention format, intervention type, weekly intervention frequency, total intervention duration, single intervention duration and intervention evaluation at different time points are set for the 782 subjects of the 12 included publications.

Results

Twelve randomized controlled trials with a total sample size of 782 subjects are included, including 393 subjects in the experimental group and 389 subjects in the control group. The meta-analysis shows that yoga exercise intervention is effective in improving sleep quality in breast cancer patients [SMD = -0.40, 95% CI: (-0.71, -0.09), P = 0.01]; yoga exercise intervention focusing on positive meditation [SMD = -0.55, 95% CI: (-1.08, -0.03), P = 0.04] is effective in improving sleep; yoga exercise intervention two or three times a week is effective in improving sleep quality [SMD = -0.69, 95% CI: (-1.19, -0.19), P = 0.007]; yoga exercise intervention for 6-8 weeks significantly improves sleep quality [SMD = -0.86, 95% CI: (-1.65, -0.08), P =0.03]; and evaluation immediately after the end of intervention improves sleep outcomes [SMD = -0.17, 95% CI: (-0.33, 0.00), P = 0.05], while differences in sleep quality improvement are not statistically significant for the remaining subgroup outcomes (P > 0.05).

Conclusion

The available evidence suggests that yoga exercise intervention has good effects on improving sleep quality in breast cancer patients. Positive meditation intervention type, intervention frequency of two or three times per week, total intervention duration of 6-8 weeks and evaluation immediately after the end of intervention are shown to be effective in improving sleep quality.

Mind-Body Therapies for Sleep Disturbance among Patients with Cancer: A Systematic Review and Meta-analysis

OBJECTIVE

s: To assess whether mind-body therapies (MBTs) are effective for relieving sleep disturbance among patients with cancer.

DESIGN

Systematic review and meta-analysis of randomized controlled trials (RCTs).

METHODS

Seven English electronic databases were searched from the date of inception to September 2022. All RCTs that included adults (≥18 years) who were treated with mindfulness, yoga, qigong, relaxation, and hypnosis were screened. The outcome was subjective and/or objective sleep disturbance.The revised Cochrane tool (RoB 2.0) was applied to evaluate the risk of bias. The RevMan software was applied to assessed each outcome according different control groups and assessment time points. Subgroup analyses were performed according to different categories of MBTs.

RESULTS

Sixty-eight RCTs (6339 participants) were identified. After requesting for missing data from corresponding authors of included RCTs, 56 studies (5051 participants) were included in the meta-analysis. The meta-analysis showed a significant immediate effect of mindfulness, yoga, relaxation, and hypnosis on subjective sleep disturbance, compared with usual care or wait list control, and the effect of mindfulness lasted at least 6 months. For objective sleep outcomes, we observed significant immediate effects of yoga on wake after sleep onset and of mindfulness on sleep onset latency and total sleep time. Compared with active control interventions, MBTs had no significant effect on sleep disturbance.

CONCLUSIONS

Mindfulness, yoga, relaxation, and hypnosis were effective in sleep disturbance severity reduction among patients with cancer at post-intervention, and the effect of mindfulness lasted at least 6 months. Future MBTs studies should apply both objective and subjective sleep measurement tools.

Characteristics of salivary cortisol and alpha-amylase as psychobiological study outcomes in palliative care research

BACKGROUND

Psychosocial interventions are rapidly emerging in palliative care. However, randomized trials often fail to provide evidence for their effectiveness with regard to patient-reported outcomes. Stress biomarkers could complement self-report data, but little is known about their feasibility, acceptance, and interpretability.

METHODS

Therefore, we designed a randomized crossover trial in which 42 patients in a palliative care unit participated in both a brief mindfulness intervention (MI) and a resting state control condition (CC) on two consecutive afternoons. On each day, we collected four saliva samples in 20-min intervals using Salivettes^© to determine salivary cortisol (sCort) and alpha-amylase (sAA) concentration levels. At all measurement points, self-rated well-being and stress as well as cardiovascular markers were assessed. Baseline measurements further included self-rated quality of life and clinician-rated functional status.

RESULTS

78.6% of the patients provided the maximum number of 8 saliva samples and 62.2% reported no subjective difficulties with the sampling procedures. 66.6% (sCort) and 69.6% (sAA) of all possible samples were finally included in the analysis. Xerostomia and nausea were the main reasons for missing data. Higher sCort levels were associated with higher heart rate and lower quality of life, functional status, and heart rate variability. Corticosteroid and sedative medication as well as time since last meal were identified as potential confounders. Regarding reactivity to the MI, we found an overall decrease in sCort levels over time (b = -.03, p = .01), but this effect did not differ significantly between the study conditions (b = .03, p = .21). sAA levels were higher in men than in women. Trajectories over time did not significantly differ between the two conditions (b = -.02, p = .80) and associations with other stress and health-related constructs were weak.

CONCLUSIONS

Findings indicate that sCort might serve as a psychobiological outcome in future palliative care trials. However, future research should refine the exact measurement and conceptualization strategies for sCort in palliative care research. High attrition rates should be expected in patients with xerostomia or nausea.

Yoga, Meditation, Breathing Exercises, and Inflammatory Biomarkers with Possible Implications in COVID-19: A Systematic Review and Meta-Analysis of Randomized Controlled Trials

Introduction

COVID-19, a multisystem disease, has implications for various immunity and infection biomarkers. Yoga (Y), meditation (M), and pranayama (P), and their combinations have shown positive changes on those biomarkers among other than COVID-19 patients and healthy people. So, we aimed to document the evidence of possible implication in a systematic way.

Materials and Methods

We screened 84 full texts, published in the last ten years, from three databases, from which only 44 met the eligibility criteria, and then extracted the data related to demographic characteristics, intervention, results, and strengths and limitations in two MS-Excel grids, and then presented them in tables and figures. Furthermore, we carried out meta-analysis including subgroup and sensitivity analysis using a random effects model of 11 RCTs and reported the mean difference, heterogeneity, and p value with 95% CI and presented them with forest and funnel plots and the tables.

Results

Twenty-five biomarkers of 4023 participants (range, 15-413) from 13 countries, healthy and clinical, from both sexes above 18 years, and from mainly clinical settings, were reported. YMP intervention, in solitary or in different possible combinations with varied durations among clinical and pregnant (range, 960-4800 minutes) and healthy (960-8400 minutes, excluding two studies of 20 minutes only) participants, was reported. It was revealed that 25 biomarkers, nine among the apparently healthy, 14 among the patients, and two among the pregnant, changed favourably (p < 0.05). Furthermore, either in meta- or subgroup-analysis, mean differences of IL-6 (-1.44 pg/ml) (95% CI) (-2.33, -0.55), (p = 0.002, I ²  = 82%), Cortisol (-40.75 pg/ml) (95% CI) (-64.13, -17.38), (p = 0.0006, I ²  = 87%), and TNF-α (-3.40 pg/ml) (95% CI) (-4.83, -1.98), (p < 0.0001, I ²  = 79%) showed statistically significant changes. Nonetheless, considerable heterogeneity and publication bias were observed among the studies.

Conclusion

Although more than two dozens of biomarkers in individual studies showed favourable changes, only IL-6, Cortisol, and TNF-α produced significant combined results, even then with much less certainty. Further meta-analysis of biomarkers of COVID-19 patients is highly recommended. Registration: CRD42021283894.

L, TS S, D'Souza C, Kumar S. A Systematic Review Protocol on the Effect of Yoga Intervention on Inflammatory Biomarkers among Women with Breast Cancer

A systematic review protocol acts as a guide in the review process to prevent the introduction of bias, maintain transparency and allows reproducibility. Yoga intervention had been experimented on various health aspects such as physical functioning, health-related quality of life, psychosocial and emotional well-being among breast cancer populations, and the findings have been very encouraging. Studies are being performed on the effect of yoga intervention(s) at the molecular level by assessing the inflammatory cytokines and also stress hormones such as cortisol. This protocol is developed to escort in evaluating studies that have been performed on evidence-based yoga intervention at the level of cancer microenvironment, in women diagnosed with breast cancer, by assessing the inflammatory biomarkers and cortisol level, a primary stress marker, and a potent influence of inflammation. The findings will elucidate the picture of the cancer microenvironment as a result of yoga intervention.

Are yoga and physical activity determinants of quality of life in Polish adults? a cross-sectional study

OBJECTIVES

Yoga is an ancient form of physical activity (PA) that encompasses meditation, stretching and breathing techniques. Although the benefits of PA and associated lifestyle interventions are clear, we here addressed the paucity of evidence regarding the specific relationship between yoga and quality of life (QOL) in adults in Poland. We hypothesised that participation in PA and yoga could result in a positive impact on QOL.

DESIGN

Cross-sectional, self-administered questionnaire-based survey. Both the quantitative and qualitative variables were statistically compared. Multivariate analyses were performed using linear regression. Results were determined based on age, sex and education level; a p<0.05 was considered significant.

SETTING

Questionnaires were delivered to participants online, at high schools and universities, and in elderly communities in Poland.

PARTICIPANTS

714 polish citizens aged over 18 participated in the study; there are no specific entry and exclusion criteria besides age.

RESULTS

Statistically significant differences (p<0.05) were observed between the QOL of the physically active group (PAG) and non-PAG (N-PAG). Meanwhile, yoga practice was revealed to have a significant effect on QOL; QOL was found to be statistically higher (p<0.001) in the PAG with yoga (PAG-Y) (4.29±0.66) than in the N-PAG (3.83±0.92) and PAG without yoga (4.07±0.68).

CONCLUSIONS

The study shows that both regular PA and yoga practices could improve QOL; however, PAG-Y produced higher QOL scores than PA of other types. This outcome may be explained by the impact of physiological and psychological aspects within yoga practice. These results suggest that this unique combination impacts health more positively than other kinds of PA alone.

Psychoneuroendocrinological effects of music therapy versus mindfulness in palliative care: results from the 'Song of Life' randomized controlled trial

PURPOSE

Although research on psychosocial interventions in palliative care provided evidence for their effectiveness regarding patient-reported outcomes, few studies have examined their psychobiological effects yet. Therefore, the purpose of the present work as part of an overarching study was to investigate differential effects of music therapy versus mindfulness on subjective distress and both neuroendocrine and autonomic stress biomarkers.

METHODS

A total of 104 patients from two palliative care units were randomly assigned to three sessions of either music therapy or mindfulness. Before and after the second session (completed by 89 patients), participants rated their momentary distress and provided three saliva samples for cortisol and α-amylase analysis. Furthermore, photoplethysmography recordings were continuously assessed to calculate mean heart rate and heart rate variability. Data were analyzed using multilevel modeling of all available data and sensitivity analysis with multiply imputed data.

RESULTS

Between 67 and 75% of the maximally available data points were included in the primary analyses of psychobiological outcomes. Results showed a significant time*treatment effect on distress (b =  - 0.83, p = .02) indicating a greater reduction in the music therapy group. No interaction effects were found in psychobiological outcomes (all p > .05), but multilevel models revealed a significant reduction in cortisol (b =  - 0.06, p = .01) and mean heart rate (b =  - 7.89, p = .05) over time following either intervention.

CONCLUSION

Findings suggest a beneficial effect music therapy on distress while no differential psychobiological treatment effects were found. Future studies should continue to investigate optimal stress biomarkers for psychosocial palliative care research.

Effect of yoga mudras in improving the health of users: A precautionary measure practice in daily life for resisting the deadly COVID-19 disease

COVID-19 is a deadly disease that affected millions of people around the world. Vaccines are presently being made available for curtailing the disease. However, many people lost their lives because of breathing problems associated with the virus infection. Science and technology have advanced a lot in the identification of the COVID-19 virus through RT-PCR tests and CT imaging. The ashtanga yoga focuses on the moral, intellectual, and health aspect improvement of individuals. This study notes that the role of Yoga (mudras) is inevitable in improving the health conditions of both the infected and noninfected persons. The effects of mudras in health care were scientifically proven, and many reputed works are there highlighting the merits of mudras. To this end, this research work proposed a set of mudras with a breathing exercise that focuses on the improvement of immunity and minimizes respiratory issues. A consistent practice of mudras with a breathing exercise for 30 min each (morning and evening) paves the way toward a healthy life. The breathing exercise proposed in this research work is Nadi Shuddi Pranayama in Virasana position and the following mudras: garuda mudra, aswini mudra, adhi mudra, prana mudra, bronchial mudra, and apana vayu mudra. The chapter comprises of the following: introduction to yoga and its scientific evidence in improving health care, related works in improving health care by mudras, and a universal practice system comprising of breathing exercise and mudras for resisting COVID-19. In theory, the outcome of this chapter focuses on the holistic improvement of health care of people particularly during crises such as the COVID-19 pandemic.

Importance of Patient Education for At-home Yoga Practice in Women With Hormonal Therapy-induced Pain During Adjuvant Breast Cancer Treatment: A Feasibility Study

Background

Osteo-articular pain (OAP) is experienced by approximately 50% of women under hormonal therapy (HT) for breast cancer (BC), which increases the risk for therapy discontinuation. This study was aimed to assess benefits of yoga practice combined with patient education (PE) for at-home practice by evaluating feasibility among BC patients under HT and measuring OAP, flexibility and satisfaction.

Methods

Feasibility was evaluated by patient adherence as accomplishment of at least 4 out of 6 supervised yoga-PE sessions along with 70% or more at-home yoga sessions. Intervention (12 weeks) included two 6-weeks periods: P1 comprising one 90-minutes supervised yoga-PE session/week and 15-minutes daily at-home yoga and P2, daily autonomous at-home yoga sessions. Evaluations (at inclusion and by the end of each period) consisted in assessment of OAP on Visual Analog Scale (VAS), forward flexibility (cm) and patient satisfaction on Likert (0-10 points) scale.

Results

Between September 2018 and May 2019 we included 24 patients of median 53 years (range 36-72). Feasibility was validated by 83% successful adherence rate. Pain was significantly reduced from median VAS of 6 [range 4-10] to 4 [range 0-7] at the end of both P1 and P2 (p < 0.01), albeit with no difference between P1 and P2. Forward flexibility improved by a median gain of 8 cm (end of P2) and median satisfaction score of 10/10 [range 8-10].

Conclusion

Combined physiotherapy-yoga-PE intervention is a feasible strategy to increase at-home yoga practice with potential benefit on pain, flexibility, and satisfaction, thus prompting further evaluations in larger randomized multicenter trials.

Effectiveness of Yoga Lifestyle on Lipid Metabolism in a Vulnerable Population-A Community Based Multicenter Randomized Controlled Trial

Background: Dyslipidemia poses a high risk for cardiovascular disease and stroke in Type 2 diabetes (T2DM). There are no studies on the impact of a validated integrated yoga lifestyle protocol on lipid profiles in a high-risk diabetes population. Methods: Here, we report the results of lipid profile values of 11,254 (yoga 5932 and control 5322) adults (20–70 years) of both genders with high risk (≥60 on Indian diabetes risk score) for diabetes from a nationwide rural and urban community-based two group (yoga and conventional management) cluster randomized controlled trial. The yoga group practiced a validated integrated yoga lifestyle protocol (DYP) in nine day camps followed by daily one-hour practice. Biochemical profiling included glycated hemoglobin and lipid profiles before and after three months. Results: There was a significant difference between groups (p < 0.001 ANCOVA) with improved serum total cholesterol, triglycerides, low-density lipoprotein, and high-density lipoprotein in the yoga group compared to the control group. Further, the regulatory effect of yoga was noted with a significant decrease or increase in those with high or low values of lipids, respectively, with marginal or no change in those within the normal range. Conclusion: Yoga lifestyle improves and regulates (lowered if high, increased if low) the blood lipid levels in both genders of prediabetic and diabetic individuals in both rural and urban Indian communities.

Effects of yoga on immune function: A systematic review of randomized controlled trials

OBJECTIVE

This systematic review attempts to confirm the added evidence to assess the effect of yoga on immune function.

METHODS

The Cochrane Library, Embase, PsycINFO, PubMed, and Web of Science electronic databases were searched according to the PRISRMA method to identify randomized controlled trials (RCTs) on the immunological effects of yoga published in the English language from January 1, 2017, to December 31, 2020. This review could only be descriptively summarized because of heterogeneity of the included RCTs.

RESULTS

Eleven potential trials were identified and included in this review. Quality appraisal of included trials ranged from 3 for unclear risk of bias and 8 for high risk of bias. There is evidence from 11 RCTs that yoga may have favorable effects for reducing the levels of anti-inflammatory markers.

CONCLUSIONS

Yoga may be used as a complementary intervention for clinical populations or healthy individuals.

Longitudinal Changes in Sleep: Associations with Shifts in Circulating Cytokines and Emotional Distress in a Cancer Survivor Population

BACKGROUND

Sleep disturbances are associated with numerous mood disorders. Similarly, anxiety and depression are associated with modulation of the psychoneuroimmune (PNI) axis. This study hypothesized that changes in both monitored and self-reported measures of sleep would relate to changes in circulating cytokine levels in an emotionally distressed population of cervical cancer survivors.

METHODS

Biospecimens, patient-reported outcome (PRO) measures, and actigraphy were collected from cervical cancer survivors enrolled in a biobehavioral clinical trial. Longitudinal changes over a 4-month period were examined. Sleep time measured by actigraphy and PRO were analyzed for correlative changes with emotional distress and serum cytokines (n = 71).

RESULTS

Longitudinal change in the actigraph measure of sleep time was inversely associated with changes in depression and anxiety (test for linear trend, p = 0.02 and p = 0.05 respectively), as well as acute-phase response/pro-inflammatory cytokines (test for linear trend, p = 0.003, interleukin (IL)-2; 0.022, IL-1β; 0.0002, IL-6; and 0.049, tumor necrosis factor α). Conversely, changes in self-reported sleep problems were related to an increase in depression and anxiety (p = 0.001 and p = 0.01 respectively), the T helper 2 (Th2) cytokine IL-5 (p = 0.027), and the counter-regulatory cytokine IL-10 (0.016).

CONCLUSION

This study showed that an increase in sleep time or decrease in sleep problems corresponded with a reduction in self-reported emotional distress and attenuation of pro-inflammatory, Th2, and counter-regulatory cytokines. Our results support sleep measurement as a meaningful biobehavioral variable in cancer survivorship. This study also indicates that sleep investigators should be aware that choice of methodology might influence concordance with different classes of immune parameters.

The effects of yoga on dyspnea, sleep and fatigue in chronic respiratory diseases

PURPOSE

This study was carried out to find out the effects of yoga applied to chronic respiratory disease patients on dyspnea, sleep quality and fatigue.

MATERIAL AND METHOD

The study was conducted between May and August 2020 as a randomized controlled study. 'Personal Information Form', 'Respiratory Functions Monitoring Form', 'COPD and Asthma Fatigue Scale (CAFS), "Asthma and COPD Sleep Impact Scale (CASIS)" and Modified Medical Research Council Dyspnea Scale (mMRC) were used in data collection.

RESULTS

When the post-test mean scores of the patients in the experimental and control group were compared, it was found that CAFS, CASIS and mMRC mean scores of the patients in the experimental group decreased positively compared to the patients in the control group and the difference between was found to be statistically significant (p < 0.05).

CONCLUSION

Yoga has been found to reduce the severity of dyspnea and fatigue and improve sleep quality in chronic respiratory diseases.

A scoping review of studies exploring leisure-time physical activity in adults diagnosed with advanced cancer

OBJECTIVES

Despite improving survival rates, people with advanced cancer face several physical and psychosocial concerns. Leisure-time physical activity (LPA) has been found to be beneficial after cancer diagnosis, but little is known about the current state of research exploring LPA in advanced cancer. Our objectives were to (a) map the literature examining LPA in people with advanced cancer, (b) report on the terms used to describe the advanced cancer population within the literature, and (c) examine how the concept of LPA is operationalized within the literature.

METHOD

Our scoping review followed Arksey and O'Malley's methodological framework. We performed a search of 11 electronic databases and supplementary sources (February 2018; database search updated January 2020). Two reviewers independently reviewed and selected articles according to the inclusion criteria: English-language journal articles on original primary research studies exploring LPA in adults diagnosed with advanced cancer. Descriptive and thematic analyses were performed.

RESULTS

Ninety-two articles met our criteria. Most included studies were published in the last decade (80%) and used quantitative methods (77%). Many study populations included mixed (40%), breast (21%), or lung (17%) cancers. Stages 3-4 or metastatic disease were frequently indicated to describe study populations (77%). Several studies (68%) described LPA programs or interventions. Of these, 78% involved structured aerobic/resistance exercise, while 16% explored other LPA types.

SIGNIFICANCE OF RESULTS

This review demonstrates a recent surge in research exploring LPA in advanced cancer, particularly studies examining exercise interventions with traditional quantitative methods. There remains insufficient knowledge about patient experiences and perceptions toward LPA. Moreover, little is known about other leisure activities (e.g., Tai Chi, dance, and sports) for this population. To optimize the benefits of LPA in people with advanced cancer, research is needed to address the gaps in the current literature and to develop personalized, evidence-based supportive care strategies in cancer care.

Stress and coping in women with breast cancer:unravelling the mechanisms to improve resilience

Breast cancer diagnosis, surgery, adjuvant therapies and survivorship can all be extremely stressful. In women, concerns about body image are common as a result of the disease and can affect interpersonal relationships, possibly leading to social isolation, increasing the likelihood for mood disorders. This is particularly relevant as women are at greater risk to develop anxiety and depressive symptoms in response to highly stressful situations. Here we address the mechanisms and the pathways activated as a result of stress and contributing to changes in the pathophysiology of breast cancer, as well as the potential of stress management factors and interventions in buffering the deleterious effects of chronic stress in a gender perspective. An improved understanding of the biological mechanisms linking stress-management resources to health-relevant biological processes in breast cancer patients could reveal novel therapeutic targets and help clarifying which psychosocial interventions can improve cancer outcomes, ultimately offering a unique opportunity to improve contemporary cancer treatments.

Raising burden of non-communicable diseases: importance of integrating Yoga and Naturopathy at primary care level

Primary health care is a vital component in health care delivery. Non-communicable diseases (NCD's) are rising like a major threat to human survival, which is expected to account for 75% of the total mortality by 2030. Lifestyle and behavioural changes are reckoned as the way ahead. Yoga and Naturopathy, a drugless system of medicine has intersecting paradigms which addresses all planes of health effectively. Yoga and Naturopathy through its holistic approach educate and make the people responsible for their own health. It has shown its efficacy in alleviating and preventing various NCD's. A systematic approach should be initiated, which can channelize the integration of Yoga and Naturopathy at the primary care level considering its cost-effectiveness and efficacy over NCD's.

Comparative Effectiveness of Cheonwangbosimdan (Tian Wang Bu Xin Dan) Versus Cognitive-Behavioral Therapy for Insomnia in Cancer Patients: A Randomized, Controlled, Open-Label, Parallel-Group, Pilot Trial

Cancer patients have a 2 times higher prevalence of insomnia than healthy populations and cancer-related insomnia has received minimal attention while insomnia can aggravate the rehabilitation of cancer patients. Cheonwangbosimdan is a Korean herbal medicine generally used to relieve sleep deprivation, however, few studies presented the effects of Cheonwangbosimdan on cancer-related insomnia. The purpose of study is to examine the feasibility of Cheonwangbosimdan treatments for cancer patients. Twenty-two participants were allocated into a Cheonwangbosimdan or cognitive-behavioral therapy for insomnia (CBT-I) control group by equal number. The intervention group took Cheonwangbosimdan liquid once in a day and attend visits once a week for 4 weeks. The CBT-I group underwent individualized behavioral therapy 4 times in 4 weeks. The primary outcome is changes in the Insomnia Severity Index (ISI) from baseline to the end of the trial. Responses to the Pittsburgh Sleep Quality Index (PSQI), Epworth Sleepiness Scale (ESS), Zung Self-Rating Anxiety Scale (SAS), Brief Fatigue Inventory (BFI), Euroqol-5 Dimensions-5 Levels (EQ-5D-5L), and Eastern Cooperative Oncology Group Performance Status (ECOG-PS) were secondary outcomes used to evaluate the quality of sleep. Outcomes were measured at a follow-up visit (visit 5) in the fifth week of the trial. There is no difference between 2 groups, but both groups showed tendency to alleviate cancer insomnia symptoms. SAS-K showed significant difference between the 2 groups (P < .001), as treatment group score was highly lowered than control group score. The study can contribute to more attentive care for insomnia in cancer patients.

Yogic meditation improves objective and subjective sleep quality of healthcare professionals

OBJECTIVE

Our aim was to evaluate the impact of yogic meditation in sleep quality of healthy pediatric healthcare professionals.

METHOD

Subjects were randomized into a meditation group (MG, n = 32), who attended a yogic meditation class held for eight weeks, or a control group (CG, n = 32). Polysomnography (PSG) and Pittsburgh Sleep Quality Index (PSQI) scores were determined at baseline and after eight weeks.

RESULTS

The PSQI overall score was lower (p = 0.024) in the MG. Reported sleep latency (p = 0.046) and MG sleep latency (p = 0.028) were lower in the MG at eight weeks. PSG showed a time effect (p = 0.020) on decreasing minutes of wake after sleep onset in the MG. There were strong and significant correlations between PSG and PSQI variables. There was a significant time effect on heart rate (p = 0.001) in the MG.

CONCLUSION

Yogic meditation may be used as an integrative health tool to foster improvements in the health-related aspects of healthcare professionals' lives.

Feasibility and Pilot Efficacy Testing of Integrated Yoga and Shirodhara (Ayurvedic Oil-Dripping) Intervention on Clinical Symptoms, Cognitive Functions and Sleep Quality of Adults with Anxiety Disorder

Background:

Beneficial effects of yoga therapy in anxiety disorders (ADs) are known. Traditional texts describe usefulness of Ayurvedic oil-dripping, Shirodhara technique, in relieving anxiety. Thus, present study was planned to assess the feasibility and synergistic value of Shirodhara as an add-on to yoga therapy in adults with AD.

Materials and Methods:

Thirty adults (males = 14, females = 16) admitted in a residential holistic health care center with an age range of 29.66 ± 6.63 years and diagnosis of one of the ADs (generalized AD, n = 18; social phobia, n = 8; and panic AD, n = 4) as per mini-international neuropsychiatric interview (M. I. N. I. English version 5.0) by a psychiatrist were randomly divided into two groups: (1) integrated yoga-based lifestyle program (YT; n = 15) and (2) YT + Ayurveda (YA; n = 15). Both groups continued to receive conventional treatment and were on stable medications throughout the study period except in cases of emergency. Assessments were done by an independent assessor at baseline and after 2 weeks of intervention for clinical symptoms (HAM-A, State and Trait Anxiety Inventory, and Brief Psychiatric Rating Scale), sleep quality (sleep rating questionnaire), and cognition (Stroop test and digit letter substitution test) using standard validated tools. Parametric tests were applied using SPSS 10.0 to analyze the data.

Results:

Twelve subjects in yoga group and thirteen subjects in YA group completed the trial. No side effects were reported in any of the groups. Within-group comparisons showed a significant improvement in clinical symptoms, cognition and sleep quality in both the groups. Between-group comparisons showed significantly better scores in Stroop word task for YA group as compared to YT group. Furthermore, there was a trend toward better improvement in sleep quality for YA group.

Conclusion:

Adding of Shirodhara technique to YT was feasible and may be useful in improving executive memory and sleep quality in adults with ADs.

Correlation among mental resilience, perceived stress, and sleep quality in elderly patients with functional dyspepsia

BACKGROUND

Repeated epiodes of functional dyspepsia (FD) in the elderly tend to affect the psychological mood and sleep quality of patients. Sleep disorders and negative psychological mood can affect each other, forming a vicious circle. In this study, the psychological resilience, perceived pressure, and sleep quality of elderly FD patients were investigated, in order to provide important objective evidence for clinical management of this population.

AIM

To analyze the correlation among perceived stress, mental resilience, and sleep quality in elderly FD patients.

METHODS

One hundred and twenty elderly patients with FD admitted to the Second Hospital of Jinhua City, Zhejiang Province from March 2017 to June 2019 were selected as study subjects, and Pittsburgh sleep quality index (PSQI), perceived stress scale (PSS), and mental resilience scale (CD-RISC-10) were used to analyze the sleep quality, perceived stress, and mental resilience.

RESULTS

Mean PSS score was 15.3 ± 4.8, mean mental resilience score was 26.1 ± 6.2, and mean PSQI score was 7.3 ± 2.7. Mean mental resilience scores were negatively correlated with PSS scores and PSQI scores (r = -0.58, -0.41, P < 0.05). PSS scores were positively correlated with PSQI scores (r = 0.33, P < 0.05). PSS scores can positively predict PSQI scores (β= 0.31, P < 0.05), and negatively predict PSQI scores (β= -0.28, P < 0.05).

CONCLUSION

Elderly FD patients have poor sleep quality, and perceived pressure and mental resilience are risk factors affecting sleep quality. In clinical practice, sleep can be improved by reducing psychological pressure.

Progress in psycho-oncology with special reference to developing countries

PURPOSE OF REVIEW

Psycho-oncology has completed 25 years. There is growing recognition of the psychosocial needs of persons living with cancer and the role of sociocultural factors in addressing the needs. This review addresses the research in developing countries relating to distress associated with living with cancer and psychosocial care.

RECENT FINDINGS

There is growing recognition of the emotional needs, understanding of the sociocultural aspects of the emotional responses of persons, caregivers, role of resilience and posttraumatic growth and spirituality in cancer care. Psychosocial aspects of cancer are largely influenced by social, economic, cultural, religious and health systems. A number of innovative approaches to care like use of yoga, financial and material support and involvement of caregivers have been implemented. A positive development is the increasing professional attention to document and develop innovative care programmes.

SUMMARY

A significant proportion of the general population are living with cancer. There are significant psychosocial needs largely influenced by social, economic, cultural, religious aspects of the communities. There are a wide range of interventions from self-care to professional care to address the needs. In developing countries, there is need for longitudinal studies of psycho-social experiences, develop interventions that are culturally appropriate, along with enhanced use of information technology along with evaluation of interventions.

Effect of yoga exercise on the quality of life and upper extremity volume among women with breast cancer related lymphedema: A pilot study

PURPOSE

This pilot study aimed to evaluate the effect of an 8-weeks-yoga intervention on quality of life and upper extremity edema volume in women with breast cancer related lymphedema.

METHODS

This was a controlled trial with pre-post design. A total of 40 women with breast cancer related lymphedema were randomly assigned into an intervention or control groups. The intervention group participated in a yoga exercise class for 8 weeks, in a twice a week instructor-led practice and once a week home practice. Outcomes were EORTC QLQ_C30 to measure quality of life, and water displacement volume-meter to measure upper extremity edema volume. The outcomes were evaluated at baseline, 4th and 8th week. Data were analyzed using SPSS.

RESULTS

Four weeks after the intervention, a significant difference was observed between the groups with respect to role functioning of quality of life (P = 0.03). Eight weeks after the intervention, a significant difference was observed between groups concerning physical and emotional functioning of quality of life (P < 0.05). The changing trend in physical, role, emotional, and cognitive functioning had increased, and in some scales such as fatigue, pain, insomnia, and financial difficulties the scores were reduced in the intervention group. Regarding edema volume, no significant difference was found between both groups on the 4th and 8th week after the intervention (P > 0.05).

CONCLUSION

As yoga exercise might improve physical, role, and emotional functioning of quality of life as well as reduce fatigue, pain, and insomnia, using this intervention can be suggested amongst women with breast cancer related lymphedema.

Yoga for symptom management in oncology: A review of the evidence base and future directions for research

Because yoga is increasingly recognized as a complementary approach to cancer symptom management, patients/survivors and providers need to understand its potential benefits and limitations both during and after treatment. The authors reviewed randomized controlled trials (RCTs) of yoga conducted at these points in the cancer continuum (N = 29; n = 13 during treatment, n = 12 post-treatment, and n = 4 with mixed samples). Findings both during and after treatment demonstrated the efficacy of yoga to improve overall quality of life (QOL), with improvement in subdomains of QOL varying across studies. Fatigue was the most commonly measured outcome, and most RCTs conducted during or after cancer treatment reported improvements in fatigue. Results also suggested that yoga can improve stress/distress during treatment and post-treatment disturbances in sleep and cognition. Several RCTs provided evidence that yoga may improve biomarkers of stress, inflammation, and immune function. Outcomes with limited or mixed findings (eg, anxiety, depression, pain, cancer-specific symptoms, such as lymphedema) and positive psychological outcomes (such as benefit-finding and life satisfaction) warrant further study. Important future directions for yoga research in oncology include: enrolling participants with cancer types other than breast, standardizing self-report assessments, increasing the use of active control groups and objective measures, and addressing the heterogeneity of yoga interventions, which vary in type, key components (movement, meditation, breathing), dose, and delivery mode.

The Effects of High-Temperature Weather on Human Sleep Quality and Appetite

High-temperature weather appears in high frequency, big strength, and long duration in the summer. It is therefore important to study the effects of high-temperature weather on sleep quality and appetite. Ten healthy college students were selected as subjects. The experiment conditions were divided by the daily maximum temperature into 28 °C, 32 °C, 36 °C, and 38 °C. The objective sleep quality was measured by an intelligent sleep monitoring belt, and the subjective sleep quality was measured by a questionnaire survey. The subjective appetites were assessed by a visual analog scale (VAS), and the objective appetites were assessed by the meal weight and the meal time. For sleep quality, the objective results indicated that the sleep quality at 32 °C was the best, followed by 28 °C, while the sleep quality at 36 °C and 38 °C was the worst. Significant effects were mainly reflected in sleep duration and shallow sleep. The subjective results showed that temperature had significant effects on sleep calmness, difficulty in falling asleep, sleep satisfaction, and sleep adequateness. For appetite, the VAS results indicated that high temperatures mainly led to a reduction of appetite at lunch time. The meal weights of lunch were larger than those of supper except for 28 °C, and the meal time of lunch and supper was longer than that of breakfast. The meal time of lunch was longer than that of supper except for 36 °C. This paper can provide a study method and reference data for the sleep quality and appetite of human in high-temperature weather.

Impact of Yoga on Inflammatory Biomarkers: A Systematic Review

BACKGROUND

Many chronic conditions, including heart disease, cancer, and rheumatoid arthritis, are associated with underlying chronic inflammatory processes. Literature reviews have analyzed a variety of integrative therapies and their relationships with chronic inflammation. This systematic review is unique in reporting solely on yoga's relationship with inflammation. Its purpose was to synthesize current literature examining the impact of yoga interventions on inflammatory biomarkers in adults with chronic inflammatory-related disorders.

METHOD

Searches of several electronic databases were conducted. Inclusion criteria were (a) English language, (b) sample age >18 years old, (c) yoga interventions involving postures with or without yoga breathing and/or meditation, and (d) measured inflammatory biomarkers.

RESULTS

The final review included 15 primary studies. Of these, seven were rated as excellent and eight as average or fair. There was considerable variability in yoga types, components, frequency, session length, intervention duration, and intensity. The most common biomarkers measured were interleukin-6 ( n = 11), C-reactive protein ( n = 10), and tumor necrosis factor ( n = 8). Most studies reported positive effects on inflammatory biomarkers ( n = 11) from baseline to post yoga intervention. Analysis of the dose showed higher total dose (>1,000 min) resulted in greater improvements in inflammation.

CONCLUSION

This review suggests that yoga can be a viable intervention to reduce inflammation across a multitude of chronic conditions. Future studies with detailed descriptions of yoga interventions, measurement of new and well-established inflammatory biomarkers, and larger sample sizes are warranted to advance the science and corroborate results.

Improvement of well-being in cancer patients by yoga training

Background: Cancer patients frequently suffer from a reduced physical activity. Non-pharmacological interventions, such as yoga, provide opportunities to deal with these symptoms. The aim of this study is to evaluate the effect of yoga on the well-being of cancer patients.Methods: Between 2015 and 2017, we analyzed the effects of yoga on the well-being of cancer patients. Fifty-one patients received yoga training specifically designed to address cancer-related problems. Before the start (SoS) and after the end (EoS) of training, the WHO-5 well-being index was used to evaluate patients’ perception.Results: WHO-5 scores significantly improved from 47.1±21.4 at SoS to 69.7±15.1 at EoS. Patients in the middle age group (EoS–SoS: 28.0±20.6) showed a significantly higher benefit (p<0.005) compared with age groups <40 years (EoS–SoS: 10.7±15.4) and >60 years (EoS–SoS: 16.0±12.1). Patients with low initial scores benefited most from yoga.Conclusion: Our study showed that yoga training under experienced supervision could serve as a beneficial complementary treatment in cancer patients. Best effects were observed in patients with highly reduced well-being and 40–60-year-old patients.
