Effectiveness of Baduanjin Exercise on Quality of Life and Psychological Health in Postoperative Patients With Breast Cancer: A Systematic Review and Meta-analysis

The effect of Tai Chi/Qigong on depression and anxiety symptoms in adults with Cancer: A systematic review and meta-regression

OBJECTIVE

We expand on prior systematic reviews of Tai chi/Qigong (TCQ) practice on depression or anxiety symptoms in adults with cancer to estimate the mean effect of TCQ on depression and anxiety in randomized controlled trials. Additionally, we perform moderator analysis to examine whether effects vary based on patient features, TCQ stimuli properties, or characteristics of research design.

METHODS

Guided by PRISMA guidelines, we located articles published before August 31, 2023 using a combination of electronic database search and a complementary manual search through reference lists of articles and published reviews. Two separate multilevel meta-analyses with random-effects model were employed to estimate the overall effect of TCQ on depression and anxiety respectively. Further, multilevel meta-regression analysis was utilized to examine moderating effects based on moderators derived from patient features, TCQ stimuli properties, or characteristics associated with research design. Meta-analyses were performed in R4.0.0 and certainty of evidence with GRADEpro software.

RESULTS

The TCQ intervention yielded a standardized mean effect size of 0.29 (95% CI, 0.18 to 0.40) for anxiety, indicating homogeneity among the included studies. Conversely, for depression, the standardized mean effect size was 0.35 (95% CI, 0.14 to 0.55), signifying heterogeneity: reductions were larger when the trial primary outcome, predominantly function-related outcomes, changed significantly between the TCQ and control group.

CONCLUSIONS

TCQ practice exhibits small-to-moderate efficacy in alleviating depression and anxiety symptoms among cancer patients and survivors. Moreover, patients with depressive symptoms for whom TCQ intervention coupled with improvements in function-related outcomes manifested greater antidepressant effect.

The Importance of Hypoxia-Related to Hemoglobin Concentration in Breast Cancer

The importance of hemoglobin (Hgb) as a novel prognostic biomarker in predicting clinical features of cancers has been the subject of intense interest. Anemia is common in various types of cancer including breast cancer (BC) and is considered to be attributed to tumoral hypoxia. Cancer microenvironments are hypoxic compared with normal tissues, and this hypoxia is associated with Hgb concentration. Recent preclinical documents propose a direct or indirect correlation of intratumoral hypoxia, specifically along with acidity, with Hgb concentration and anemia. Analysis of the prognostic value of Hgb in BC patients has demonstrated increased hypoxia in the intratumoral environment. A great number of studies demonstrated that lower concentrations of Hgb before or during common cancer treatments, such as radiation and chemotherapy, is an essential risk factor for poor prognostic and survival, as well as low quality of life in BC patients. This data suggests a potential correlation between anemia and hypoxia in BC. While low Hgb levels are detrimental to BC invasion and survival, identification of a distinct and exact threshold for low Hgb concentration is challenging and inaccurate. The optimal thresholds for Hgb and partial pressure of oxygen (pO2) vary based on different factors including age, gender, therapeutic approaches, and tumor types. While necessitating further investigations, understanding the correlation of Hgb levels with tumoral hypoxia and oxygenation could improve exploring strategies to overcome radio-chemotherapy related anemia in BC patients. This review highlights the collective association of Hgb concentration and hypoxia condition in BC progression.

Potential roles of PIWI-interacting RNAs in breast cancer, a new therapeutic strategy

Breast cancer (BC) has been the focus of numerous studies aimed at identifying novel biological markers for its early detection. PIWI-interacting RNAs (piRNAs), a subset of small non-coding RNAs, have emerged as potential markers due to their aberrant expression in various cancers. PiRNAs have recently gained attention due to their aberrant expression in various cancers, including BC. PiRNAs, exhibit diverse biological activities, such as epigenetic regulation of gene and protein expression and their association with cell proliferation and metastasis has been well-established. As the field of non-coding RNAs rapidly evolves, there is great anticipation that therapies targeting piRNAs will advance swiftly. This review will delve into the various biological functions of piRNAs, such as gene suppression, transposon silencing, and epigenetic regulation of genes. The review will also highlight the role of piRNAs as either progenitors or suppressors in cancers, with a particular focus on BC. Lastly, it will touch upon the potential of piRNAs as biomarkers and therapeutic targets for BC.

The role of the BTLA-HVEM complex in the pathogenesis of breast cancer

Breast cancer (BC) is widely recognized as a prevalent contributor to cancer mortality and ranks as the second most prevalent form of cancer among women across the globe. Hence, the development of innovative therapeutic strategies is imperative to effectively manage BC. The B- and T-lymphocyte attenuator (BTLA)-Herpesvirus entry mediator (HVEM) complex has garnered significant scientific interest as a crucial regulator in various immune contexts. The interaction between BTLA-HVEM ligand on the surface of T cells results in reduced cellular activation, cytokine synthesis, and proliferation. The BTLA-HVEM complex has been investigated in various cancers, yet its specific mechanisms in BC remain indeterminate. In this study, we aim to examine the function of BTLA-HVEM and provide a comprehensive overview of the existing evidence in relation to BC. The obstruction or augmentation of these pathways may potentially enhance the efficacy of BC treatment.

Association between thyroid disorders and extra-thyroidal cancers, a review

Thyroid hormone has been shown to have both tumor-promoting and tumor-suppressing actions, which has led to significant debate over its involvement in the development of cancer. Proliferation, apoptosis, invasiveness, and angiogenesis are all aspects of cancer that are affected by the thyroid hormones T3 and T4, according to research conducted in animal models and in vitro experiments. The effects of thyroid hormones on cancer cells are mediated by many non-genomic mechanisms, one of which involves the activation of the plasma membrane receptor integrin αvβ3. Typically, abnormal amounts of thyroid hormones are linked to a higher occurrence of cancer. Both benign and malignant thyroid disorders were found to be associated with an increased risk of extra-thyroidal malignancies, specifically colon, breast, prostate, melanoma, and lung cancers. The purpose of this review was to shed light on this link to define which types of cancer are sensitive to thyroid hormones and, as a result, are anticipated to respond favorably to treatment of the thyroid hormone axis.

Impact of traditional Chinese Baduanjin exercise on menstrual health among international female students studying in China: a randomized controlled trial

Background

Menstrual symptoms were the common complaints of international female students during the acculturation period, and the symptoms negatively affected the daily life and school performance of those women. The present study aimed to evaluate the effectiveness of the traditional Chinese Baduanjin exercise on reducing menstrual symptoms for international female students studying in China during the acculturation period.

Methods

We conducted a randomized controlled trial among 62 international female students who suffered menstrual symptoms during the first 6 months after arriving in China. The study was carried out at three campuses of the two largest universities in the capital of a province in south-central China from March to October 2021. After screening, participants were randomly assigned to a control or intervention group. The intervention group engaged in 24 weeks of Baduanjin exercise for at least 30 min per day. The menstrual symptoms, sociocultural adaptation, perceived stress, and sleep quality were evaluated at baseline, the 12th week, and the 24th week. The chi-square test or Fisher's exact test, paired sample t-test, and multivariate analysis of variance (MANOVA)were adopted to analyze the data using SPSS 25.0.

Results

Totally, 62 participants were enrolled in this study from 30 countries. Their mean age was 27.87 ± 5.58 years. None of the participants reported an adverse event. The results of the MANOVA test showed that the traditional Chinese Baduanjin exercise reduced the total score of MSQ among international female students (intervention: 47.83 ± 8.71 vs. control: 65.12 ± 16.86; F = 19.49, P < 0.01). In addition, the results of the MANOVA indicated statistically significant decreases in scores for the two subscales of MSQ: premenstrual symptoms (intervention: 17.07 ± 3.33 vs. control: 28.42 ± 7.56; F = 44.70, P < 0.01)and menstrual pain (16.03 ± 4.53 vs. 19.58 ± 5.14; F = 6.50, P < 0.05). Moreover, the results showed that traditional Chinese Baduanjin exercise reduced the scores of the sociocultural adaptation level, the perceived stress level, and sleep quality and improved the blood progesterone hormone and blood estrogen hormone.

Conclusion

Regular Baduanjin exercise is a safe, acceptable, and effective form of exercise to promote international female students' menstrual health, reduce stress levels, and improve sleep quality.

Comparative efficacy of mind-body exercise for depression in breast cancer survivors: A systematic review and network meta-analysis

BACKGROUND

As pharmacotherapy often leads to adverse reactions, mind-body exercise (MBE) treatments have become a more popular option for treating depression in people living with breast cancer (BC). However, the most effective type of MBE treatment for this population remains unclear.

AIMS

The aim of this systematic review and network meta-analysis (NMA) was to compare the efficacy of the different MBE modes for depression in people with BC.

METHODS

A systematic search for randomized controlled trials (RCTs) from inception to March 25, 2023, was conducted in the following database: EMBASE, PubMed, Web of Science, Cochrane Library, China National Knowledge Infrastructure, Wanfang Data, China Biology Medicine, OpenGrey, and ClinicalTrials.gov. A traditional meta-analysis was conducted using the random-effects model to directly assess the effectiveness of various MBE interventions. Stata 16.0 software was used for performing the NMA.

RESULTS

The NMA was performed in 32 eligible RCTs including 2361 participants. The efficacy of MBE treatments on depression was ranked as the following: Liuzijue (surface under the cumulative ranking curve [SUCRA] = 95.4%) > Tai chi (SUCRA = 76.9%) > yoga (SUCRA = 55.0%) > Baduanjin (SUCRA = 53.9%) > Pilates (SUCRA = 38.6%) > dance (SUCRA = 30.2%) > Qigong (SUCRA = 28.1%) > control (SUCRA = 21.9%).

LINKING EVIDENCE TO ACTION

Our research showed that Liuzijue and Tai chi might be the most significantly effective MBE intervention for mitigating depression among BC survivors. Healthcare professionals could consider recommending Liuzijue and Tai Chi as a complementary therapy for BC survivors who experience depression.

Effects of exercise on immune cells with tumor-specific activity in breast cancer patients and survivors: a systematic review and meta-analysis

Exercise is effective for improving the physical and psychological health of breast cancer patients. However, there is still controversy around its role on the immune system. Therefore, this systematic review and meta-analysis is aimed to evaluate the effect of chronic exercise on the number and activity of the immune cells that can contribute to anti-tumor immune responses, such as natural killers (NK) cells, CD + 4, or CD + 8. The main hypothesis of this study was that exercise could improve the immune system or, at least, there will not be a reduction in the number or activity of immune cells because of exercise. The search was conducted in the PubMed and Web of Science databases. Out of 244 studies reviewed, 10 studies met the inclusion criteria. The studies included in the meta-analyses showed mixed results and no significant (p > 0.05) positive or negative effects of exercise interventions in women with breast cancer. Therefore, the current evidence indicates that exercise does not significantly improve or reduce the immune system; thus, the prescription of exercise must not be discouraged due to the effects on the number and activity of immune system cells, but should be recommended due to the well-known benefits in quality of life, physical function or fatigue, and the absence of negative effects on the immune system. Further studies are needed to evaluate the effects according to the type of exercise, the type of cancer, or the timing of the intervention.

Evidence for Choosing Qigong as an Integrated Intervention in Cancer Care: An Umbrella Review

Cancer is the second leading cause of noncommunicable disease death, with an increasing incidence. Qigong practice can moderate non-intrinsic, modifiable risk factors that act on the stress response using physical movements, breathing, and focused attention. The purpose of this umbrella review is to provide a concise summary to facilitate an evidence-based decision to integrate Qigong into cancer patients' care. Relevant systematic reviews and meta-analyses were identified and retrieved from the JBI database, Cochrane Library, PubMed, Embase, and CINAHL. Of all of the studies assessed, none found evidence of a risk to cancer patients, indicating that Qigong is a safe practice that can be used even by frail patients. The overall quality of life, cancer-related fatigue, and cognitive impairment were improved by Qigong. Different Qigong programs have different impacts on sleep quality and gastrointestinal problems, suggesting that longer practice sessions are required to achieve improvements. To maintain Qigong's effectiveness, an ordinary practice is essential, or such effectiveness will wear off. The use of biological markers in efficacy assessments needs to be more systematically studied. However, positive WBC, RBC, and CRP trends in Qigong practitioners are evident. Higher-quality clinical studies are necessary to measure variables more closely related to Qigong functioning and consider cancer's multifactorial nature.

Effects of baduanjin exercise on blood glucose, depression and anxiety among patients with type II diabetes and emotional disorders: A meta-analysis

BACKGROUND

Diabetes mellitus (DM) is a group of metabolic disorders reflected by high blood glucose levels and lack of hormone insulin. Notably, T2DM patients are three times more likely to report depression than the general population. Conventional exercise training programs have been shown to be beneficial for T2DM, but less is known regarding the effects of Baduanjin exercise on hemoglobin A1c (HbA1c) and psychological measures among this unique group. Therefore, this systematic review and meta-analysis aimed to investigate the effects of Baduanjin exercise on HbA1c, depression, and anxiety among type 2 diabetes mellitus (T2DM) patients with emotional disorders.

METHODS

The potential literature was searched from six electronic databases (PubMed, MEDLINE, CINAHL, Scopus, Wanfang, and CNKI) from their inception to July 2022. The randomized controlled studies that investigated the effects of Baduanjin on HbA1c, depression , and anxiety in T2DM with emotional disorders were included. The effect sizes were calculated using the random-effect models with a 95% confidence interval (CI). The Physiotherapy Evidence Database (PEDro) scale was employed to assess the study quality.

RESULTS

Eleven studies involving 755 T2DM participants with emotional disorders were analyzed in this study. The pooled results showed that Baduanjin had significant improvements in HbA1c (SMD = 0.75, 95% CI 0.46 to 1.04, p < 0.001), depression (SMD = 0.69, 95% CI 0.30 to 1.08, p < 0.01) and anxiety (SMD = 0.98, 95% CI 0.44 to 1.53, p < 0.01) compared to the control group.

CONCLUSION

Findings suggest that Baduanjin exercise may effectively alleviate HbA1c, depression, and anxiety among T2DM patients with emotional disorders. However, more well-designed studies are required to further substantiate the promising findings.

Effects of Baduanjin exercise on quality-of-life and exercise capacity in patients with heart failure: A systematic review and meta-analysis

PURPOSE

Exercise training is an efficient non-pharmacological intervention for patients with heart failure (HF). This study aimed to objectively evaluate the effects of Baduanjin exercise on the quality of life (QOL) and exercise capacity in patients with HF.

METHODS

PubMed, Embase, the Cochrane Library, Chinese National Knowledge Infrastructure (CNKI), and Wanfang data were searched from the date of their inception until 30 September 2022. All randomised controlled trials (RCTs) evaluating the effects of Baduanjin exercise on QOL and exercise capacity in patients with HF were selected. The primary outcomes were QOL, assessed using the Minnesota Living with Heart Failure Questionnaire (MLHFQ), and exercise capacity, evaluated using the 6-min walking test (6-MWT). A meta-analysis was performed by comparing the MLHFQ domain scores. Review Manager 5.3 and Stata 14.0, were used for the data analysis.

RESULTS

Baduanjin exercise showed a favourable improvement of the overall QOL (mean difference = -8.25; 95% confidence interval: -13.62 to -2.89; P = 0.003) and exercise capacity (mean difference = 118.49; 95% confidence interval: 52.57 to 184.41; P = 0.0004). Meta-analyses of the MLHFQ domain score indicated that Baduanjin exercise significantly improved the patients' physical (mean difference = -2.83; 95% confidence interval: -3.76, -1.90; P < 0.00001), emotional (mean difference = -2.52; 95% confidence interval: -3.67 to -1.37; P < 0.0001), and general QOL (mean difference = -2.61; 95% confidence interval: -5.17 to -0.06; P = 0.05), based on the decrease in the MLHFQ domain score. Marked statistical heterogeneity (I2> 70%) was observed for all the QOL and exercise capacity outcomes.

CONCLUSIONS

Baduanjin exercise is a safe, feasible, and acceptable intervention that can improve the QOL and exercise capacity in patients with HF. However, more RCTs with rigorous research designs are needed to assist in the rehabilitation of such patients.

Effects of Baduanjin exercise in nasopharyngeal carcinoma patients after chemoradiotherapy: a randomized controlled trial

OBJECTIVE

To evaluate the effects of traditional Chinese Baduanjin Qigong exercises on the physical and psychological recovery of patients with nasopharyngeal carcinoma after chemoradiotherapy.

METHODS

Eighty-eight nasopharyngeal carcinoma patients who had completed chemoradiotherapy were randomly divided into the Baduanjin intervention group (n = 44) and the control group (n = 44). Patients in the intervention group practised Baduanjin exercise for 12 weeks, with the frequency of 40 min a day and 5 days a week after discharge from the hospital. Participants in the control group received usual care. Outcome indicators included quality of life (QOL), complications, cancer-related fatigue (CRF), sleep quality, anxiety, and depression. The intention-to-treat and per-protocol populations were compared using univariate analysis of variance. Partial eta squared was used as a measure of the effect size.

RESULTS

A total of 75 patients completed the study. In the intention-to-treat analysis, after 12 weeks of exercise intervention, there were significant increases in the global FACT-H&N (95% CI = 2.09 to 11.47, η_p² = 0.088), social/family well-being (95% CI = 0.13 to 2.26, η_p² = 0.055), emotional well-being (95% CI = 0.34 to 2.44, η_p² = 0.074), and head and neck cancer subscale scores (95% CI = 0.17 to 3.86, η_p² = 0.052) in the Baduanjin group compared with the control group at the 12th week. In the per-protocol analysis, there were significant increases in the global FACT-H&N (95% CI = 4.11 to 11.75, η_p² = 0.190), physical well-being (95% CI: 0.50 to 3.04, η_p² = 0.096), social/family well-being (95% CI: 0.32 to 2.15, η_p² = 0.090), emotional well-being (95% CI: 0.60 to 2.53, η_p² = 0.125), functional well-being (95% CI: 0.25 to 2.49, η_p² = 0.075), and head and neck cancer subscale (95% CI: 1.08 to 4.08, η_p² = 0.139) scores in the Baduanjin group compared with the control group at the 12th week.

CONCLUSION

The findings in this study indicate that Baduanjin exercise is an effective and appropriate intervention for improving quality of life and is worthy of recommendation and implementation by oncology nurses in the rehabilitation process of patients with nasopharyngeal carcinoma.

Impact of physical exercise programs in breast cancer survivors on health-related quality of life, physical fitness, and body composition: Evidence from systematic reviews and meta-analyses

Background

Breast cancer is the most common cancer worldwide, and despite remarkable progress in its treatment, the survivors' quality of life is hampered by treatment-related side effects that impair psychosocial and physiological outcomes. Several studies have established the benefits of physical exercise in breast cancer survivors in recent years. Physical exercise reduces the impact of treatment-related adverse events to promote a better quality of life and functional outcomes.

Aim

This study aims to provide an overview of systematic reviews and meta-analyses on the effect of physical exercise on the health-related quality of life, cardiorespiratory fitness, muscle strength, and body composition of breast cancer survivors.

Methods

PubMed and Cochrane databases were searched for systematic reviews and meta-analyses from January 2010 to October 2022. The main focus was ascertaining the effectiveness of physical exercise in breast cancer survivors undergoing curative treatment (surgery and/or radiotherapy and/or chemotherapy). Two reviewers independently screened the literature, extracted the data, and assessed the risk of bias in the included studies.

Results

A total of 101 studies were identified, and 12 were yielded for final analysis. The eligible studies included nine systematic reviews/meta-analyses, one meta-analysis/meta-regression, and two systematic reviews. The number of randomised clinical trials included in each review varied from 11 to 63, and the number of participants was from 214 to 5761. A positive and significant effect of different physical exercise interventions on health-related quality of life was reported in 83.3% (10 studies) of the eligible studies. Physical exercise also improved cardiorespiratory fitness (3 studies; 25%) and showed to be effective in reducing body weight (3 studies; 25%) and waist circumference (4 studies; 33.3%).

Conclusions

Our results suggest that physical exercise is an effective strategy that positively affects breast cancer survivors' quality of life, cardiorespiratory fitness, and body composition. Healthcare professionals should foster the adoption of physical exercise interventions to achieve better health outcomes following breast cancer treatments.

Baduanjin exercise for patients with breast cancer: A systematic review and meta-analysis

OBJECTIVE

Baduanjin exercise is a traditional Chinese mind-body exercise routine characterized by slow, coordinated, and sequential movements. We have performed the first meta-analysis on the main effect of Baduanjin exercise in patients with breast cancer.

METHODS

This study followed the 2020 PRISMA guideline. We searched for randomized controlled trials in PubMed, Embase, Cochrane Library, Web of Science, Clinical Trials.gov, Chinese National Knowledge Infrastructure, Wanfang Data Information Site, Chinese Biomedical Database, and Chinese Science and Technique Journals Database through 31 August 2022. Data were analyzed for the outcomes of quality of life, anxiety, and depression. Review Manager 5.4 software was used for data analysis.

RESULTS

Seven randomized controlled trials with a total of 537 patients with breast cancer were examined. Compared with the control therapies, Baduanjin exercise significantly improved the total quality of life score (SMD = 0.83; 95 % CI, 0.58-1.08; P < 0.00001) and in two associated domains: emotional well-being (SMD = 0.67; 95 % CI, 0.26-1.07; P = 0.001), functional well-being (SMD = 0.55; 95 % CI, 0.30-0.79; P < 0.00001) and breast cancer subscale (SMD = 0.39; 95 % CI, 0.02-0.77; P = 0.04). Meanwhile, it significantly reduced anxiety score (SMD = - 0.60; 95 % CI, - 1.15 to - 0.05; P = 0.03) and in depression score (SMD = - 0.70 95 % CI, - 0.97 to - 0.42; P < 0.00001). None adverse event was reported.

CONCLUSION

The meta-analysis suggests that Baduanjin exercise is an effective and safe exercise for improving quality of life and alleviating depression and anxiety in patients with breast cancer. Significant methodological concerns of the included studies limit the interpretation of the results. For future trials of Baduanjin exercise on BC, we highlight the importance of adopting more rigorous study design in terms of assessor blinding, hypothesis/purpose blinding, allocation concealment, objective outcome selection and consistent reporting of adverse events.

An exercise prescription for patients with lung cancer improves the quality of life, depression, and anxiety

Introduction

Lung cancer has the highest rates of morbidity and mortality among all cancers. Patients with lung cancer inevitably confront psychosocial discomforts and progressively experience depression and anxiety that potentially impact the clinical outcomes [e.g., quality of life (QoL)]. These mental disorders in patients with lung cancer may effectively be alleviated with prescribed Chinese traditional mind-body exercises. This study aimed to determine the effect of the exercise prescription containing Chinese traditional mind-body exercise on QoL, depression, and anxiety in patients with lung cancer.

Methods

In this study, 52 patients with non-small cell lung cancer (NSCLC) recruited from the China-Japan Friendship Hospital were divided into two groups, namely, the experimental group (N = 26) and the control group (N = 26). The experimental group was treated with an 8-week exercise prescription containing aerobic and resistance training. The control group received the usual care during the study period. The QoL, depression, and anxiety were separately investigated using EORTC QLQ-C30, EORTC QLQ-LC13, the Self-Rating Depression Scale (SDS), and the Self-Rating Anxiety Scale (SAS) at baseline and post-intervention. The scores of questionnaires were analyzed using the paired sample and independent sample t-tests to explore the intragroup and intergroup differences, respectively.

Results

The EORTC QLQ-C30 scores for physical functioning, role functioning, emotional functioning, and global QoL in the experimental group at post-intervention were significantly higher than those at baseline. The EORTC QLQ-C30 scores for fatigue, pain, dyspnea, and insomnia in the experimental group at post-intervention were significantly lower than those at the baseline. The SDS scores (baseline: 57.74 ± 8.77 vs. post-intervention: 51.42 ± 7.31, p < 0.05) and the SAS scores (baseline: 56.63 ± 9.39 vs. post-intervention: 49.16 ± 7.83, p < 0.05) in the experimental group at post-intervention were significantly lower than those at baseline.

Conclusions

The 8-week exercise prescription containing moderate-intensity Baduanjin (5 days per week) can effectively alleviate QoL, depression, and anxiety in patients with NSCLC. Our exercise prescription is an effective supportive treatment for lung cancer patients with depression and anxiety.
