A Web- and Mobile-Based Intervention for Women Treated for Breast Cancer to Manage Chronic Pain and Symptoms Related to Lymphedema: Results of a Randomized Clinical Trial

Comparison of the effects of different functional exercise sequences on lymphedema in breast cancer: protocol for an exploratory randomised controlled cross-over trial

INTRODUCTION

Breast cancer-related lymphedema (BCRL) is a common postoperative complication of breast cancer. It develops in a chronic and vicious cycle. Once lymphedema occurs, it cannot be cured and bring serious physiological, psychological, social and economic burden to patients. Upper limb functional exercises are an effective and convenient intervention for managing lymphedema. However, the optimal exercise sequence remains unclear. Therefore, we aim to compare the effects of exercise sequences under the guidance of commonly used exercise sequences and lymphatic flow theory.

METHODS

An exploratory randomised controlled cross-over trial will be conducted. 32 patients with BCRL are randomly allocated into two groups (group A and group B). Group A patients will perform functional exercise from wrist joint to shoulder joint, and the exercise direction of group B is opposite to that of group A, that is, from shoulder joint to wrist joint end. Exercise time is once a day, each 20-30 min, for 2 weeks. After 2 weeks of washout period, A and B groups of exchange exercise sequences (exercise frequency and duration unchanged). The primary outcome is upper limb circumference, and secondary outcomes are upper limb function and lymphedema symptoms.

ETHICS AND DISSEMINATION

This study protocol is presented in accordance with the Standard Protocol Items: Recommendations for Interventional Trials guidelines. All participants will sign a written informed consent. The research ethics regional committee of Shanghai Seventh People's Hospital has approved the study. Regardless of the outcome of this study, the results will be published in open-access journals to ensure public access.

The Utilization of e-Health in Lymphedema Care: A Narrative Review

Background: Electronic health (e-Health), refers to technologies that can be utilized to enhance patient care as well as collect and share health information. e-Health comprises several umbrella terms, including telehealth, mobile health, e-Health, wearables, and artificial intelligence. The types of e-Health technologies being utilized in lymphedema (LE) care are unknown. Method: In this narrative review, a search of published research on the utilization of e-Health technologies in LE-related care was conducted. Results: Five different types of e-Health modalities were found (robotics, artificial intelligence, electronic medical records, smart wearable devices, and instructive online information) spanning 14 use cases and 4 phases of care (preventative, diagnostic, assessment, and treatment phases). Broad e-Health utilization examples were found including robotic-assisted surgery to reduce the likelihood of LE after lymphadenectomy, machine learning to predict patients at risk of filarial-related LE, and a novel wearable device prototype designed to provide lymphatic drainage. Conclusions: e-Health has reported merit in the prevention, diagnoses, assessment, and treatment of LE with utilization demonstrating cutting edge applicability of e-Health for achieving optimal patient care and outcomes. As technology continues to advance, additional research into the utilization of e-Health in LE care is warranted.

Effects of digital self-management symptom interventions on symptom outcomes in adult cancer patients: A systematic review and meta-analysis

PURPOSE

Digital self-management (SM) interventions targeting symptom relief have demonstrated positive as well as null outcomes, whereas no study has synthesized the effect of the interventions. In this study, we aimed to evaluate the effectiveness of digital SM symptom interventions on symptom outcomes in adult cancer patients.

METHODS

A systematic review and meta-analysis based on the previous scoping review was conducted. Six databases (PubMed, CINAHL, Embase, the Cochrane Library, RISS [Korean], and KoreaMed [Korean]) were searched. Population was adult cancer patients. Intervention was SM interventions applying digital health tool targeting symptom management. Comparison was usual care, waitlist controls or active controls. The primary outcome was symptom burden, and the secondary outcomes were individual symptoms.

RESULTS

Our meta-analysis of 32 randomized controlled trials (RCTs) including 7888 patients demonstrated that digital SM symptom interventions had a significant effect on reducing symptom burden (effect size [ES] = -0.230) and relieving pain (ES = -0.292), fatigue (ES = -0.417), anxiety (ES = -0.320), and depression (ES = -0.261).

CONCLUSIONS

Digital SM interventions can improve symptom outcomes in adult cancer patients. Oncology nurses should be aware that digital SM interventions have demonstrated promising outcomes in cancer patient care.

Strategies in activating lymphatic system on symptom distress and health-related quality of life in patients with heart failure: secondary analysis of a pilot randomized controlled trial

Background

Abnormal interstitial fluid accumulation remains the major cause for patients with heart failure (HF) to endure a myriad of distressing symptoms and a decline in their health-related quality of life (HRQoL). The lymphatic system is essential in regulating fluid balance within the interstitial compartment and has recently been recognized as an important target for the prevention and mitigation of congestion. This study aimed to investigate the effects of exercises in activating lymphatic system on symptom distress and HRQoL among patients with HF.

Methods and results

This was a pre-determined, secondary analysis of the TOLF-HF [The-Optimal-Lymph-Flow for Heart Failure (TOLF-HF)] study, a two-arm pilot randomized controlled trial evaluating the preliminary effects of the lymphatic exercise intervention in enhancing interstitial decongestion among patients with HF. Participants were randomized to receive either a four-week TOLF-HF program in addition to standard care or standard care alone. The Chinese version of the Minnesota Living with Heart Failure Questionnaire (MLHFQ) was employed to measure symptom distress and HRQoL before and after the intervention. Data analyses included descriptive statistics, the independent sample t-test, Pearson's chi-square test, the Mann-Whitney U test, and covariance analysis. Of the 66 patients enrolled, 60 completed the study. The study results exhibited that the TOLF-HF intervention were effective in alleviating both physical and psychological symptom distress. The intervention group yielded significantly lower MLHFQ total scores in comparison to the control group. The odd ratio of achieving meaningful improvement in HRQoL in TOLF-HF group was 2.157 times higher than those in the control group.

Conclusions

The TOLF-HF program focusing on activating lymphatic system was effective in alleviating physical and psychological symptom distress as well as improving HRQoL for patients with HF. The tolerability, feasibility, and effectiveness of the TOLF-HF intervention make it a promising intervention for patients to manage HF.

Precise management system for chronic intractable pain patients implanted with spinal cord stimulation based on a remote programming platform: study protocol for a randomized controlled trial (PreMaSy study)

BACKGROUND

Spinal cord stimulation (SCS) is a surgical technique used in patients with chronic intractable pain, and its effectiveness and safety have been validated by multiple studies. However, to maintain an optimal and steady long-term effect is still challenging. Here, we report a new management paradigm integrating smartphone application and remote programming. Chronic pain patients with SCS implants can monitor their pain status on the phone and change stimulation parameters accordingly. The PreMaSy study is a randomized controlled trial to evaluate the clinical effectiveness and safety of this precise management system.

METHODS

Patients with chronic intractable pain will be screened for eligibility, and 82 participants are anticipated to be enrolled in this trial. After the electrode implantation, the stimulation effectiveness will be tested. Participants with a reduction of more than 50% in the visual analog scale (VAS) will receive implantation of an implantable pulse generator and randomized (1:1) into the experimental group or control group. All participants will be asked to take online follow-ups and complete assessments using a smartphone application. Daily pain characteristic assessments and monthly quality of life questionnaires are integrated into the App, and participants will be required to complete these assessments. The daily VAS for pain intensity will be monitored and a threshold will be set based on baseline VAS score. The interventional appointment will be scheduled once the threshold is reached. The primary outcome is the health condition and quality of life assessed by the five-level EuroQol five-dimensional questionnaire (EQ-5D-5L). Utility values of EQ-5D-5L will be assessed at baseline and 1, 3, and 6 months post-operative.

DISCUSSION

The PreMaSy study aims to evaluate the effectiveness and safety of a novel App-based, patient-centered, self-assessment management system for chronic intractable pain. A randomized controlled trial is designed to test the non-inferiority of this precise management system compared to the monthly online follow-ups. It is also expected to yield valuable experiences regarding precision medicine.

Avatar-Based Strategies for Breast Cancer Patients: A Systematic Review

There is a lack of studies to determine if avatar-based protocols could be considered an efficient and accurate strategy to improve psychological well-being in oncology patients, even though it represents a growing field of research. To the best of our knowledge, this is the first systematic review addressing the effectiveness of avatar-based treatments to enhance quality of life (QoL) and psychological well-being in breast cancer patients. The purpose of this study was to review the scientific literature of those studies involving avatar-based technology and breast cancer patients in order to answer the following questions. (1) Are avatar-based strategies useful to im-prove QoL and psychological well-being (anxiety and depression symptoms) in breast cancer patients? (2) Which is the best way to develop avatar-based protocols for breast cancer patients? We conducted a systematic review of the peer-reviewed literature from EBSCO, Ovid, PubMed, Scopus, and Web of Science (WOS), following the PRISMA statements and using "avatar + breast cancer" or "avatar + cancer" as keywords. Studies which were published in either English or Spanish and which addressed QoL and psychological well-being in breast cancer patients were reviewed. The results will contribute to developing innovative avatar-based strategies focused on breast cancer patients.

Mobile Apps and Quality of Life in Patients With Breast Cancer and Survivors: Systematic Literature Review

BACKGROUND

Side effects of breast cancer treatment may persist long into survivorship, reducing quality of life (QOL) in patients with breast cancer and survivors. There is growing evidence for the use of digital health technologies, such as mobile apps, to support self-management, decrease symptom burden, and improve QOL in patients with cancer. However, an updated overview of the effects of mobile apps on QOL and well-being in patients with breast cancer and survivors is needed.

OBJECTIVE

The aim of this review was to provide an overview of breast cancer-specific, mobile app-driven lifestyle or behavioral interventions in patient care through to survivorship and their impact on QOL and mental well-being.

METHODS

A systematic search of PubMed, Scopus, and Web of Science was conducted to identify relevant studies. The inclusion criteria were limited to original studies involving a trial of a mobile app-driven lifestyle or behavioral intervention for patients with breast cancer or survivors and using QOL or well-being measures. The results of the studies that met the inclusion criterion were then synthesized in text and table format. The quality of the evidence was assessed with the Cochrane risk-of-bias tool.

RESULTS

A total of 17 studies with the number of participants ranging from 23 to 356 met the inclusion criterion. Of the 17 reviewed studies, 7 (41%) delivered an app-only intervention, and 10 (59%) combined an app with additional supporting materials, such as SMS text messaging, telecoaching, wearables, or printed materials. Among the 17 reviewed studies, 6 (35%) focused on aiding patients with breast cancer during the active treatment phase (excluding ongoing hormone therapy), whereas the remaining 11 (65%) focused on survivorship. The majority of the studies (14/17, 82%) observed some positive effects on QOL or well-being measures.

CONCLUSIONS

The results of the review indicate that mobile apps are a promising avenue for improving QOL and well-being in breast cancer care. Positive effects were observed in patients undergoing active treatment in all reviewed studies, but effects were less clear after chemotherapy and in long-term survivors. Although lifestyle and behavioral digital interventions are still being developed, and further research should still be pursued, the available data suggest that current mobile health apps aid patients with breast cancer and survivors.

Exercises in activating lymphatic system on fluid overload symptoms, abnormal weight gains, and physical functions among patients with heart failure: A randomized controlled trial

Background

Fluid overload remains a vexing problem in management of heart failure. The lymphatic system that plays the central role in fluid homeostasis has recently been explored as a potential target to counteract tissue fluid overload. The goal of the study was to evaluate the preliminary effects of exercises in activating lymphatic system on fluid overload symptoms, abnormal weight gains, and physical functions for patients with heart failure.

Methods and results

A pilot, pre- and post-test, randomized clinical trial was conducted to recruit a total of 66 patients who were randomized to receive either a 4-week The-Optimal-Lymph-Flow for Heart Failure (TOLF-HF) program or usual care alone. The primary outcome was the prevalence and burden of the fluid overload symptoms. Findings of the trial showed that the TOLF-HF intervention was effective in reducing the prevalence or burden of the majority of fluid overload symptoms. TOLF-HF intervention also demonstrated significant improvement in the outcomes of abnormal weight gains (MD: -0.82; 95% CI: -1.43 to -0.21; P = 0.010) and physical functions (F = 13.792, P < 0.001).

Conclusions

The TOLF-HF program focusing on activating lymphatic system through the performance of therapeutic lymphatic exercises holds the promise as an adjuvant therapy for patients with heart failure to manage fluid overload symptoms, reduce abnormal weight gains, and improve physical functions. Future larger-scale study with longer duration of follow-up is needed.

A systematic review of m-health apps on managing side effects of breast cancer treatment

PURPOSE

After breast cancer treatment, women with breast cancer may experience distress caused by treatment side effects, both in physical and psychological aspects. Technology use is increasing in favor among women. Therefore, it is essential to update the scientific evidence regarding mobile and web apps' effectiveness in managing the side effects of breast cancer treatments for breast cancer survivors. The purpose of this systematic review was to investigate the scientific evidence on the effectiveness of mobile and web apps in managing the side effects of breast cancer treatments among this group.

METHODS

A literature search was conducted using ScienceDirect, Scopus, PubMed, CINAHL, and Cochrane. Published papers in English focused on mobile and web apps and the side effects of breast cancer treatment in breast cancer survivors were selected. The search reviewed studies from January 2011 to December 2021. From a total of 925 retrieved manuscripts, 11 studies were included for analysis.

RESULTS

The findings showed that mobile apps were more frequently used and more likely to be an effective method for managing the side effects of breast cancer treatment among breast cancer survivors. The content in web or mobile apps for breast cancer survivors should include five categories: (1) information about cancer, (2) overview of cancer care, (3) opportunities for interaction with other people, (4) symptom management strategies, and (5) feedback about cancer treatment side effect management. However, a few studies examined the effects of a combination of mobile and web apps in managing breast cancer treatment side effects. Therefore, future research is needed to examine solo and combination use. In addition, more rigorous studies are warranted to examine these interventions.

CONCLUSIONS

Nurses may refer survivors to these resources to obtain more information and effectively manage the signs and symptoms of breast cancer and its treatment side effects.

Strategies in activating lymphatic system to promote lymph flow on lymphedema symptoms in breast cancer survivors: A randomized controlled trial

Background

Many breast cancer survivors face long-term postoperative challenges as a result of developing lymphedema symptoms and chronic lymphedema. The-Optimal-Lymph-Flow (TOLF) program is an intervention based on physiological-cognitive-behavioral principles that teaches patients self-management strategies to activate lymphatic system and promote lymph flow to decrease lymphatic pain, reduce the risk and severity of lymphedema.

Objective

The purpose of this pilot clinical trial was to evaluate the use of TOLF program as an early intervention on improving lymphedema symptom experience (i.e., symptom number, symptom severity, symptom distress, and the impact of symptoms on patients’ activities of daily living) and optimizing lymph fluid levels (measured by the arm volume differences) among breast cancer survivors.

Methods

This study is a parallel, randomized clinical trial. A total of 92 breast cancer patients were randomly assigned to either the TOLF intervention group or the control group focusing on promoting arm mobility. Data were collected at baseline and end of the trial at the 3-month post intervention. The Breast Cancer and Lymphedema Symptom Experience Index was used to measure lymphedema symptom experience. Anthropometric measurements were used for circumferential arm measurements. Generalized linear mixed-effects models were used to evaluate the trial outcomes.

Results

Significant improvements of lymphedema symptom experience were found in patients in the TOLF intervention group in comparison with patients in control group: the number of lymphedema symptoms (P<0.001) and the severity of lymphedema symptoms (P<0.001) as well as the impact of symptoms on patients’ daily living function (P<0.001). Patients in both groups showed improvements in all study outcomes over the 3 months, whereas those in the TOLF group gained greater benefits in reducing the number and severity of lymphedema symptoms. Moreover, the TOLF group had significantly fewer patients with ≥5% arm volume differences ([5/45] vs [13/43], P=0.035) at the study endpoint.

Conclusions

Findings of the study demonstrated positive outcomes of relieving lymphedema symptom experience, optimizing arm circumference and halting the progression of lymphedema status in breast cancer survivors receiving TOLF intervention during early postoperative time. Given its feasibility, acceptability, and effectiveness, this program may be incorporated in routine breast cancer care.

Leveraging Telehealth for the Management of Breast Cancer: A Systematic Review

Background: Breast cancer affects 2.3 million women and kills 685,000 globally, making it the most prevalent cancer. The telemedicine modality has been used to treat the symptoms associated with breast cancer recovery. Objectives: To analyze the effectiveness of telemedicine to help women recover from the treatment-associated effects and promote overall recovery from breast cancer. Methods: Four databases were queried for published literature from the last 10 years. The systematic literature review was conducted in accordance with the Kruse Protocol and reported in accordance with PRISMA 2020. Results: Five interventions were identified in the literature, with the most dominant being eHealth and mHealth. The other interventions were telephone, video teleconference, and a combination of eHealth and mHealth. There were positive effects of these telemedicine interventions in 88% of the studies analyzed. Telemedicine is shown to positively affect physical and mental health, sleep outcomes, quality of life, and body image. The largest barriers to the adoption of telemedicine interventions are training, cost, workflow, time of providers, and low reimbursement. Conclusion: Telemedicine offers promise to both providers and breast cancer survivors to improve the physical and mental health detriments of both cancer and its associated treatments. It also helps women develop healthy habits to reduce the risk of reoccurrence.

Effect of a telehealth-based exercise intervention on the physical activity of patients with breast cancer: A systematic review and meta-analysis

Telehealth-based exercise intervention as a non-pharmacological intervention has gradually emerged in breast cancer (BC), which shows feasibility and high levels of patient satisfaction. This systematic review aims to identify the effect of telehealth-based exercise interventions on the physical activity (PA) of patients with BC. We searched CENTRAL, CINAHL, PsycINFO, EMBASE, PubMed, Web of Science, ClinicalTrials.gov, CNKI, Wanfang, VIP, and SinoMed. Study selection and quality appraisal were performed independently by two reviewers. The review protocol was registered in PROSPERO (CRD42022326484). Nine studies, which included 1127 patients with BC, were identified. Compared with usual care, the telehealth-based exercise intervention had a significantly positive effect on PA (Standardized mean difference (SMD) = 0.26, 95% confidence interval (CI) 0.09 to 0.43, P = 0.003), aerobic capacity (SMD = 0.20, 95% CI 0.03 to 0.38, P = 0.02), upper body function (Mean difference (MD) = −4.56, 95% CI −7.66 to −1.47, P = 0.004), upper muscle strength (SMD = 0.26, 95% CI 0.09 to 0.42, P = 0.002), lower muscle strength (SMD = −0.95, 95% CI −1.27 to −0.62, P < 0.00001), abdominal muscle strength (MD = 23.85, 95% CI 13.84 to 33.86, P < 0.000,01), fatigue (SMD = 0.56, 95% CI 0.13 to 1.00, P = 0.01), and quality of life (SMD = 0.26, 95% CI 0.04 to 0.49, P = 0.02). Conversely, anthropometric and body composition and pain did not differ significantly between the two groups. Telehealth-based exercise intervention improved PA, physical performance, fatigue, and quality of life of patients with BC compared with routine care, which should be promoted clinically as a comprehensive treatment for BC.

Experiences of breast cancer survivors with lymphedema self-management: a systematic review of qualitative studies

PURPOSE

This study systematically identified, evaluated, and synthesized qualitative literature on the experiences of breast cancer survivors with lymphedema self-management.

METHODS

This systematic review followed the Joanna Briggs Institute meta-aggregation approach and was guided by the ENTREQ, graded according to the ConQual approach, and evaluated using the Joanna Briggs Institute Qualitative Assessment and Review Instrument (JBI-QARI). Qualitative studies related to the experiences in lymphedema self-management among breast cancer survivors conducted until March 9, 2022, were searched. The selected studies were reviewed independently, and the data were synthesized collaboratively into core themes.

RESULTS

A total of 24 studies were included, and 85 findings resulted in three synthesis findings: (a) breast cancer survivors face challenges in lymphedema self-management, (b) breast cancer survivors are entangled in rebuilding a new balance between different roles, and (c) breast cancer survivors seek internal and external resources to regulate negative emotions.

CONCLUSIONS

Lymphedema self-management is a lifetime commitment and a challenge for breast cancer survivors, who find it difficult to adhere to self-management and cope with their problems. They require timely and continuous effective self-management education, and instrumental and emotional support from others, particularly healthcare providers and family members.

IMPLICATIONS FOR CANCER SURVIVORS

Timely self-management education and access to lymphedema treatment and related resources are important for survivors to prevent and manage lymphedema. Breast cancer survivors should develop coping skills, and family members should participate in survivors' lymphedema self-management.

The Effects of Exercise-Based Interventions on Fluid Overload Symptoms in Patients with Heart Failure: A Systematic Review and Meta-Analysis

Patients with heart failure are subjected to a substantial burden related to fluid overload symptoms. Exercise can help the lymphatic system function more effectively to prevent fluid build-up in tissues and interstitium, thus potentially mitigating the symptoms due to fluid overload. The objective of this systematic review was to examine the effects of exercise-based interventions on fluid overload symptoms among patients with heart failure. MEDLINE, Embase, Cochrane Library, and CINAHL databases were systematically searched for relevant studies published from inception to August 2021. We included randomized controlled trials that compared exercise-based interventions of different modalities and usual medical care for adult patients with heart failure and reported the effects of interventions on any symptoms related to fluid overload. A random-effects meta-analysis was used to estimate the effectiveness, and a subgroup analysis and univariate meta-regression analysis were used to explore heterogeneity. Seventeen studies covering 1086 participants were included. We found robust evidence indicating the positive effect of exercises in dyspnea relief (SMD = −0.48; 95%CI [−0.76, −0.19]; p = 0.001); the intervention length also influenced the treatment effect (β = 0.033; 95%CI [0.003, 0.063]; p = 0.04). Initial evidence from existing limited research showed that exercise-based intervention had positive effect to alleviate edema, yet more studies are needed to verify the effect. In contrast, the exercise-based interventions did not improve fatigue compared with usual care (SMD = −0.27; 95%CI [−0.61, 0.06]; p = 0.11). Findings regarding the effects of exercises on bodily pain, gastro-intestinal symptoms, and peripheral circulatory symptoms were inconclusive due to limited available studies. In conclusion, exercise-based interventions can be considered as an effective nonpharmacological therapy for patients with heart failure to promote lymph flow and manage fluid overload symptoms. Exercise-based interventions seem to have very limited effect on fatigue. More research should investigate the mechanism of fatigue related to heart failure. Future studies with high methodological quality and comprehensive assessment of symptoms and objective measure of fluid overload are warranted.
