Evaluation and management of insomnia in women with breast cancer

Acupuncture for systemic therapy-associated insomnia in patients with breast cancer: a systematic review and meta-analysis of randomized controlled trials

Background

Systemic therapy-associated insomnia is highly prevalent among patients with breast cancer. However, no meta-analysis has explored the efficacy of acupuncture for Systemic therapy-associated insomnia among patients with cancer.

Methods

According to the PRISMA Statement, randomized controlled trials (RCTs) through April 2024 were identified and extracted from PubMed, Embase, and the Cochrane CENTRAL Register of Controlled Trials. The quality of the RCTs was assessed using the Cochrane Systematic Review Handbook 5.1 and its recommended risk-of-bias assessment tool. Two independent investigators screened and extracted the data and performed statistical analysis using RevMan5.3.

Results

Of the total 411 studies identified, 4 RCTs were analyzed. The meta-analysis revealed that acupuncture significantly improved the total sleep time and sleep efficiency relative to wait-list control or sham EA among patients with breast cancer experiencing insomnia after systemic therapy (mean difference [MD] 29.86, 95% confidence interval [CI] 16.20-43.51, P < 0.0001 and MD 4.56, 95% CI 1.84-7.29, P = 0.001), reduced the pittsburgh sleep quality index (PSQI) relative to wait-list control or sham EA with an MD of -0.87 (95% CI -1.60 to -0.15, P = 0.02, I2 = 25%) in 4 weeks and an MD of -0.82 (95% CI -1.60 to -0.04, P = 0.04, I2 = 12%) in 8 weeks, and reduced the hospital anxiety and depression scale (HADS)-anxiety both in 4 weeks with an MD of -0.85 (95% CI -1.42 to -0.27, P = 0.004, I2 = 0%) and in 8 weeks with an MD of -0.94 (95% CI -1.56 to -0.32, P = 0.003, I2 = 0%. However, no significant differences in insomnia severity index (MD -2.15, 95% CI -5.07 to 0.78, P = 0.15 and MD -1.48, 95% CI -3.91 to 0.94, P = 0.23), and HADS-depression (MD -0.67, 95% CI -2.32 to 0.99, P = 0.43 and MD -0.63, 95% CI -2.39 to 1.12, P = 0.48) in 4 and 8 weeks were observed between the acupuncture group and the wait-list control or sham EA group.

Conclusion

Acupuncture has a great potential to be used in the management of systemic therapy-associated insomnia in patients with breast cancer. More studies with rigorous designs and larger sample sizes are warranted to verify the efficacy and safety of acupuncture for insomnia among patients with breast cancer.

Post-mastectomy wound care - need for an empathetic approach

Mastectomy, a surgical procedure involving the removal of breast tissue, is a common treatment option for breast cancer. Post treatment, survivors often experience both physical and psychological symptoms, which in turn delay the recovery phase. Post-mastectomy wound complications, such as infection, pain, delayed healing, seroma formation, persistent discomfort and limited mobility often lead to prolonged hospital stays and reduced quality of life. Proper wound care, including dressing changes and wound management, is crucial for optimal healing. However, mastectomy also has a significant emotional and psychological impact on patients, leading to depression, anxiety, and poor body image due to significant changes in the body such as loss of hair, unsightly scars and weight changes. Patients also feel uncomfortable when medical professionals concentrate solely on survival, rather than empathizing with them. While these emotional reactions are often expected and considered normal during breast cancer treatment, what comes as a surprise is the additional harm caused by healthcare providers' communication and behaviour when treating breast cancer patients. Despite advances in medical technology, there remains a significant gap in providing psychosocial support for breast cancer survivors. Undergoing a mastectomy is an emotionally challenging experience, and healthcare providers play a vital role in establishing the groundwork for psychological recuperation. By incorporating empathetic practices into daily patient care, healthcare providers can be trained to create an unbiased, informative, and compassionate environment, to improve patient outcomes and satisfaction. The use of compassionate communication when interacting with the patient and their care givers can foster a more nurturing atmosphere for all parties involved. By prioritizing empathy in post-mastectomy wound care, healthcare providers can enhance the overall well-being of breast cancer survivors. This review explores the physical and emotional impact of mastectomy on patients, the healing process, and the importance of integrating empathy into post-mastectomy wound care.

Non-Pharmacological Interventions for Managing the Symptoms of Depression in Women with Breast Cancer: A Literature Review of Clinical Trials

Symptoms of depression represent a significant burden to patients with breast cancer, not only because of the psychological stress associated with their diagnosis, but also because of the adverse effects of its treatment. We reviewed the clinical trials examining the management of the symptoms of depression in breast cancer patients through different non-pharmacological interventions in different databases (PubMed, Embase, Scopus, and the American Psychological Association). Cognitive behavioural therapy, interpersonal psychotherapy or psychodynamic psychotherapy, as well as acceptance and commitment therapy have been effective in improving symptoms of depression in cancer patients with moderate to severe symptoms. Physical exercise, yoga, mindfulness, and support groups have been shown to benefit patients with mild depressive symptoms. These interventions not only showed positive results in interventions in women with breast cancer in terms of the symptoms of depression, but also highlighted their benefits for comorbid anxiety, stress, and poor sleep quality; moreover, it is suggested that these interventions should be leveraged to manage mental health issues in breast cancer patients. The molecular effects of these interventions, such as the reduction in inflammatory cytokines and cortisol levels, have seldom been reported and need further studies.

Synthesis, Aromatase Inhibition, Cytotoxicity and Molecular Docking Studies of New Fluorinated and Non-Fluorinated Thiourea Derivatives of Desloratadine

Aromatase inhibitors are among the most effective treatment of the breast cancer. Aromatase catalyzes estrogen biosynthesis, which is a long-term cause of breast cancer. Current study describes the synthesis, purification of 26 new fluorinated and non-fluorinated thiourea derivatives of desloratadine (5), and their aromatase inhibition activity, cytotoxicity against cancer cell line (MDA-MB-231). Compounds 7 v and 7 l exhibited a significant anti-aromatase activity, while compounds 7 a, 7 g-h, 7 m and 7 u were also significant active against MDA-MB-231 cell line. Furthermore, the molecular docking studies revealed that active compounds form key interactions with the crucial amino acid of aromatase active site including TRP224, LEU477, CYS437, ALA438, MET374, ARG115, ILE305, and PHE221, which are responsible for the binding interactions of aromatase. All analogues were new, except 7 b and 7 k and also lacked cytotoxicity against BJ human fibroblasts, with the exception of 5 and 7 x. This selectivity makes this series particularly interesting for further studies.

Role and perception of healthcare professionals in referring cancer patients to online cognitive behavioral therapy for insomnia

PURPOSE

Insomnia represents a major issue in oncology, which can be successfully treated by online Cognitive-Behavioural Therapy for Insomnia, such as the Insomnet program. However, promoting its successful implementation in routine care requires healthcare providers' involvement. This study aimed to explore healthcare professionals' perceptions of this online program.

METHODS

This qualitative study was a part of the French Sleep-4-All-2.0 multicentric study. It explored, through two focus groups including 19 healthcare professionals of three cancer centers, their perceptions regarding their role in patient referral, and the perceived barriers and facilitators in accessing this type of intervention. The content of the focus groups was subjected to a descriptive thematic analysis.

RESULTS

Four major themes were identified: (1) ambivalent representations of online tools (including patients convinced by remote intervention, evolution of representations in relation to the health context, adapted to sleep disorders, professionals' preconceptions of online tools), (2) barriers to implementation (including few perceived barriers, forgetting patients' particularities, professionals' lack of knowledge, a possible threat to the patient-caregiver relationship, financial cost), (3) levers for implementation (including real benefits for patients, professionals who feel confident, preserved patient-caregiver relationship, institutional innovations to remedy dysfunctions), and (4) professional involvement in implementation (what they need, what to avoid, what they already do, what they see themselves doing).

CONCLUSION

Online (healthcare) services were reported to help increase access to healthcare, but that should not replace the relationship between patients and healthcare professionals. All professionals must be informed and trained to refer patients to these programs.

Auricular acupressure for insomnia in women with breast cancer: A systematic review and meta-analysis of randomized controlled trials

BACKGROUND

Breast cancer as the malignant tumor with the highest incidence and mortality rate among the global female population. Insomnia is a common complaint in breast cancer patients, more than one-third (38-47%) of breast cancer patients suffer it. Auricular acupressure (AA), a non-pharmacological therapy, has been used in the studies to intervene in insomnia in breast cancer patients. The objective of this systematic review and meta-analysis is to investigate the efficacy and safety of AA therapy in intervening with insomnia in breast cancer.

METHODS

A systematic literature search was performed for 10 databases up to January of 2024 to identify randomized control trials (RCTs). The methodological quality of RCTs was assessed independently using the Cochrane Handbook for Systematic Reviews of Interventions. The quality of evidence was evaluated with the Grading of Recommendations Assessment, Development and Evaluation approach. Data were screened and extracted independently using predesigned forms. The meta-analysis was conducted using RevMan 5.3 software, P-value < .05 means statistically significant.

RESULTS

This review included 15 studies from 3 different countries with a total of 1125 adult participants. The pooled results showed that AA significantly in improving sleep quality (mean difference [MD] = -3.36, 95% confidence interval [CI]: [-4.65, -2.07], P < .001) and life quality (MD = -7.82, 95% CI: [-14.76, -0.88], P = .03). Based on data from sleep monitoring devices, AA was valuable for improving sleep efficiency (MD = -3.63, 95% CI: [-4.19,-3.07], P = .03) in breast cancer patients. Adverse events were reported in 5 RCTs. Common adverse reactions include auricular skin allergic reaction (10/259, 3.9%), bruising (7/259, 2.7%), pain (3/259, 1.2%), and local pressure ulcers on the auricular points (2/259, 0.8%). The evidence grade was moderate because of the substantial heterogeneity among studies. Heart, Shenmen, and Subcortex were the 3 most numerous auricular points, with a total share of up to 71.70%.

CONCLUSION

This systematic review and meta-analysis demonstrates the efficacy and safety of AA in intervening insomnia in breast cancer patients, providing a basis for the selection of clinical auricular points. However, the high-quality RCTs in existence are not enough, and more rigorous trials are needed to identify the efficacy of AA and insomnia.

Prevalence of Insomnia and Related Factors Among Cancer Outpatients in China

Background

The incidence of insomnia in cancer patients is significantly higher than in the general population. Chronic insomnia imposes pronounced physical and psychological burdens on cancer patients, affecting their quality of life and survival rate. This study aims to investigate insomnia in cancer patients and further analyze potentially related factors.

Methods

Oncology outpatients treated at Fudan University Shanghai Cancer Center were consecutively recruited. Demographic information and clinical features, such as type of cancer and treatment status, were collected. Insomnia was assessed using the Insomnia Severity Index (ISI).

Results

A total of 146 patients participated in the study, with the majority suffering from breast tumors (40.4%), gastrointestinal tract tumors (18.5%), and endocrine tumors (5.8%). Among these patients, 25 (17.1%) did not report insomnia, 69 (47.3%) had subclinical insomnia, and 52 (35.6%) reached the level of clinical insomnia. Older patients aged 41-50 years (Estimate = -3.49, 95% CI, -6.99 to 0.00, p = 0.05) and those with higher education levels (Estimate = -2.72, 95% CI, -4.88 to -0.55, p = 0.01) were less likely to have higher ISI total scores. In contrast, undergoing chemotherapy (Estimate = 3.86, 95% CI, 0.53 to 7.19, p = 0.02) was associated with higher ISI total scores. Gender, age, education, treatment modalities correlated with ISI subitem scores.

Conclusion

The prevalence of insomnia is higher in oncology patients and is associated with gender, age, education, tumor type, and treatment modality. Screening and interventions for insomnia should be emphasized in the whole-course management of oncology patients.

Examining the factor structure of the Pittsburgh Sleep Quality Index and its determinants among GI cancer patients

BACKGROUND

Poor sleep quality is one of the prevalent manifestations experienced by cancer patients. There is a lack of research focusing specifically on sleep quality and affecting factors in Gastrointestinal (GI) cancer patients. This study aimed to assess the potential interaction between dietary, comorbid conditions, demographic, and socioeconomic determinants of sleep quality in GI cancer patients.

METHODS

In a cross-sectional study, the Pittsburg Sleep Quality Index (PSQI) was completed for 875 adult patients suffering from GI cancer in a referral hospital. We conducted structural equation modeling analyses to evaluate the potential interaction between dietary and socioeconomic determinants of sleep quality in GI cancer patients.

RESULTS

This study demonstrated that the PSQI encompasses two factors (perceived sleep quality and sleep disturbances) in GI cancer patients in Iran. Based on the standardized coefficients for the structural paths, the wealth index (WI) partially mediated the effect of food insecurity (FI) on the sleep quality index. There was a direct predictive effect of the WI on the PSQI (β = 0.10, P = 0.01). In addition, WI indirectly through FI (effect of WI on FI: β = -0.21, P = 0.01 & effect of FI on PSQI: β = 0.07, P = 0.03) had a negative effect on PSQI. Our finding suggested the full mediation effect of age on PSQI through the number of comorbidities (effect of age on number of comorbidities: β = 0.25, P < 0.001 & the effect of number of comorbidities on PSQI: β = 0.13, P < 0.001). Structural path outputs for gender-model indicated the full mediation effect of age on PSQI through the number of comorbidities among males and through the FI among females.

CONCLUSION

These findings highlight the importance of considering the bi-dimensional construct of the PSQI for assessing sleep quality among GI cancer patients. The current study demonstrated that food insecurity and comorbidity prevalence mediated the relationship between socio-demographic determinants of sleep quality in patients with GI cancer.

Effects of intermittent hand-foot hypothermia therapy on chemotherapy-induced peripheral neurotoxicity

PURPOSE

Chemotherapy-induced peripheral neuropathy (CIPN) is a common side effect in patients with breast cancer undergoing chemotherapy. This study aimed to assess the effects of three different intermittent hypothermia temperatures applied to the hands and feet on CIPN symptoms in patients with breast cancer undergoing chemotherapy.

METHODS

In total, 108 patients were randomly divided into three experimental groups (n = 36). Patients wore cold gloves and foot covers (groups 1-3, three 10 °C intervals from 0 to - 30 °C) for 15 min before and after each infusion. CIPN symptoms and their interference with activities of daily living (ADL) were assessed before the intervention and after the third and sixth cycles. Hypothermia tolerability and safety were also evaluated.

RESULTS

Baseline characteristics were similar across groups. After three intervention cycles, the scores were lower in group 3 than in group 1 for finger/hand numbness, toe/foot numbness, finger/hand/toe/foot discomfort, muscle/joint pain, and arm/leg weakness. After six intervention cycles, group 3 showed lower scores than group 1 for finger/hand tingling, toe/foot tingling, and difficulty maintaining balance. After six cycles of intervention, the influence of CIPN on ADL in all dimensions (except getting along with others) and the total score was lower in group 3 than in group 1. Additionally, CIPN symptoms and effects on activities of daily living were significant across time, groups, and interactions.

CONCLUSIONS

Intermittent hand-foot therapy (- 20 to - 30 °C) was the most effective for improving symptoms and ability to perform day-to-day activities. All temperatures tested were well-tolerated and safe.

Care process for breast cancer patients with sleep disturbances: a best practice implementation project

INTRODUCTION

Patients with breast cancer are 50% more likely to experience sleep disturbances during treatment. Sleep disturbances may affect physiological and psychological functions and even induce cancer recurrence. Screening, assessment, and management of sleep disturbances improves sleep quality in breast cancer patients.

OBJECTIVES

This project aimed to establish a care process for breast cancer patients with sleep disturbances in a cancer ward.

METHODS

The project was implemented using the JBI Evidence Implementation Framework, which is grounded in audit and feedback. A baseline audit examined the existing care for sleep disturbances in breast cancer patients undergoing chemotherapy. Eight criteria were applied to evaluate compliance with best practice recommendations. A JBI Getting Research into Practice (GRiP) analysis was conducted, and five barriers to recommended practices were identified. Fourteen improvement strategies were then implemented and a follow-up audit was conducted to measure changes in practice.

RESULTS

The baseline audit showed that the sleep screening rate was 71% (Criterion 1). However, for the remaining criteria (2-8), the compliance rate was 0%. After project implementation, all criteria improved. Thus, 100% of nurses received education on sleep disturbance; the screening rate increased to 90%; 100% of screened patients received comprehensive sleep assessment; and 100% of assessed patients received tailored, multimodal sleep management based on their assessment results.

CONCLUSIONS

This project improved compliance with evidence-based practices in caring for breast cancer patients with sleep disturbances. Process orientation, interdisciplinary collaboration, and leadership contributed to project success. Further studies in digitalized sleep assessment are needed to ensure the efficiency and sustainability of sleep care.

Psychological Interventions for Insomnia in Patients with Cancer: A Scoping Review

BACKGROUND/OBJECTIVES

Insomnia is a frequent and distressing symptom with limited treatment in patients with cancer. Among the available treatments for insomnia, psychological interventions are some of the most assessed. While studies and reviews show promise of interventions improving insomnia in patients with cancer, inconsistent approaches to operationalizing and measuring insomnia combined with the heterogeneity of available treatments render comparisons and synthetization difficult. This review sought to rigorously synthesize psychological interventions for patients with cancer and insomnia by describing current therapies, identifying gaps in the literature, and offering supportive interventions.

METHODS

A comprehensive search of five databases-Ovid MEDLINE, Ovid Embase, Ovid PsycInfo, EBSCO CINAHL Plus with Full Text, and Cochrane Library-was conducted through 1 August 2024. The review included randomized trials and non-inferiority trials evaluating psychological interventions for patients with various types of cancers. Twenty-one studies were included, and study quality ranged from good to excellent, according to the PEDro scale.

RESULTS

The current evidence supports the use of cognitive behavioral therapy (CBT) to treat insomnia over and above psychoeducation alone, mindfulness-based stress reduction, Brief Behavioral Therapy, the Benson Relaxation Technique, progressive muscle relaxation, mindfulness meditation, mind-body bridging, and home-based psychological nursing. Digital, minimal, and internet-based intervention modalities are effective, though professional-delivered CBT proved most effective.

CONCLUSIONS

CBT remains the most effective psychological intervention for insomnia in this population. Challenges exist regarding the implementation of CBT, so further research is warranted to identify the best psychological interventions for specific settings and subsets of patients with cancer.

Sleep quality in cancer patients: a common metric for several instruments measuring sleep quality

PURPOSE

Sleep problems are frequently observed in cancer patients. Multiple questionnaires for assessing sleep quality have been developed. The aim of this study was to present transfer rules that allow the conversion of the patients' scores from one questionnaire to another. In addition, we anchored this common metric to the general population.

METHODS

A sample of 1,733 cancer patients completed the following questionnaires: Pittsburgh Sleep Quality Index, Insomnia Sleep Index, Jenkins Sleep Scale, EORTC QLQ-C30, and the sleep scale of the EORTC QLQ-SURV100. The methods for establishing a common metric were based on Item Response Theory.

RESULTS

The main result of the study is a figure that allows the conversion from one of the above-mentioned sleep scales into another. Furthermore, the scores of the questionnaires can be transferred to theta scores that indicate the position within the group of cancer patients and also to T scores that indicate the position in relation to the general population. The correlations between the sleep scales ranged between 0.70 and 0.85.

CONCLUSIONS

The conversion rules presented in the study enable researchers and clinicians to directly compare single scores or mean scores across studies using different sleep scales, to assess the degree of sleep problems with regard to the general population, and to relate cutoff scores from one questionnaire to another.

The effects of Tai Chi and Baduanjin on breast cancer patients: systematic review and meta-analysis of randomized controlled trials

Background

Tai Chi and Baduanjin are nonpharmacological interventions that are widely applied among cancer patients.

Objective

This meta-analysis aimed to assess the effect of Tai Chi and Baduanjin on breast cancer patients by summarizing and pooling the results of previous studies.

Methods

The PubMed, Embase, Web of Science, Scopus and Cochrane Library and several databases were searched up to December 1, 2023, to identify high-quality RCTs. Relevant terms such as Tai Chi and Baduanjin were used as keywords. Stata 15.0 software and Review Manager (version 5.3; Cochrane Training) were used to screen the studies, extract the data, code the data, and perform the meta-analysis. The mean differences (MDs) and standardized mean differences (SMDs) with 95% CIs were used to calculate continuous variables. The Cochrane risk of bias assessment tool was used to evaluate the risk of bias. The PICOS framework was used to develop the following eligibility criteria: (i) population - breast cancer patients; (ii) intervention - Tai Chi and Baduanjin intervention; (iii) comparison - Tai Chi and Baduanjin group and different intervention (e.g., regular intervention, routine rehabilitation training, waiting list, sham Qigong, usual care, no intervention); (iv) outcomes - cognitive ability, shoulder joint function, anxiety, depression, fatigue, sleep quality, quality of life; and (v) study design - randomized controlled trial.

Results

From January 2013 to December 2023, we included a total of 16 RCTs involving 1247 patients. A total of 647 patients were in the experimental group and were treated with Tai Chi and Baduanjin, while 600 patients were in the control group and were treated with traditional methods. The results of our meta-analysis indicate that Tai Chi and Baduanjin yield outcomes that are comparable to those of traditional treatment methods. Specifically, Tai Chi and Baduanjin significantly increased cognitive function, increased shoulder joint function, improved sleep quality indicators and improved quality of life indicators. Furthermore, Tai Chi and Baduanjin significantly reduced anxiety symptoms, depression symptoms, and fatigue symptoms among breast cancer patients. Sensitivity analysis was performed, a funnel plot was constructed. No publication bias was indicated by Egger's or Begg's test.

Conclusion

Overall, Tai Chi and Baduanjin are viable and effective nonpharmacological approaches for treating breast cancer patients, as they yield better results than traditional treatment methods. However, these findings should be interpreted with caution due to the limited number of controlled trials, small sample sizes, and low quality of the evidence.

Sleep oscillations related to memory consolidation during aromatases inhibitors for breast cancer

Aromatase inhibitors (AIs) are associated with sleep difficulties in breast cancer (BC) patients. Sleep is known to favor memory consolidation through the occurrence of specific oscillations, i.e., slow waves (SW) and sleep spindles, allowing a dialogue between prefrontal cortex and the hippocampus. Interestingly, neuroimaging studies in BC patients have consistently shown structural and functional modifications in these two brain regions. With the aim to evaluate sleep oscillations related to memory consolidation during AIs, we collected polysomnography data in BC patients treated (AI+, n = 17) or not (AI-, n = 17) with AIs compared to healthy controls (HC, n = 21). None of the patients had received chemotherapy and radiotherapy was finished since at least 6 months, that limit the confounding effects of other treatments than AIs. Fast and slow spindles were detected during sleep stage 2 at centro-parietal and frontal electrodes respectively. SW were detected at frontal electrodes during stage 3. Here, we show lower frontal SW densities in AI + patients compared to HC. These results concord with previous reports about frontal cortical alterations in cancer following AIs administration. Moreover, AI + patients tended to have lower spindle density at C4 electrode. Regression analyses showed that, in both patient groups, spindle density at C4 electrode explained a large variance of memory performances. Slow spindle characteristics did not differ between groups and sleep oscillations characteristics of AI- patients did not differ significantly from those of both AI + patients and HC. Overall, our results add to the compelling evidence of the systemic effects of AIs previously reported in animals, with deleterious effects on cortical activity during sleep and associated memory consolidation in the current study. There is thus a need to further investigate sleep modifications during AIs administration. Longitudinal studies are needed to confirm these findings and investigation in other cancers on this topic should be conducted.

Association between perceived stress, loneliness and sleep disorders among breast cancer patients: the moderating roles of resilience

Sleep disorders are prevalent and often neglected among breast cancer patients. This study aimed to identify the association among perceived stress, loneliness, resilience and sleep disorders and to further explore whether resilience could be a moderator in the association between them and sleep disorders. A cross-sectional study was conducted by 492 female breast cancer patients. Patients were asked in response to the questionnaires including the Pittsburgh Sleep Quality Index, Perceived Stress Scale-10, the Three-Item Loneliness Scale and Resilience Scale-14. The association among perceived stress, loneliness, resilience and perceived stress/loneliness × resilience interaction with sleep disorders were examined by hierarchical multiple regression analysis. The interaction was visualized by using simple slope analysis. 36.58% of the female breast cancer patients reported sleep disorders in our study. Perceived stress and loneliness were related to sleep disorders. Resilience could moderate the relationship between them and sleep disorders. When resilience was higher, perceived stress and loneliness had a weaker impact on sleep disorders. Medical staff should systematically evaluate the internal environmental factors related to patients' sleep quality and help patients relieve their emotional distress caused by the disease through positive psychological guidance.

Effectiveness of a theory-based tailored mHealth physical activity intervention for women undergoing chemotherapy for breast cancer: A quasi-experimental study

Objectives

This study aimed to explore the effectiveness of the theory-based tailored mHealth physical activity (PA) intervention among patients with breast cancer undergoing chemotherapy.

Methods

A quasi-experimental study design was adopted. A total of 60 breast cancer patients were selected from two tertiary hospitals in Shanghai and Hangzhou City from September 2019 to August 2021. According to the admission order, 30 patients were first included in the control group, followed by 30 patients in the intervention group. A smartphone application (app) named "Breast Care" was developed based on social cognitive theory, self-efficacy theory, and the theory of planned behavior. The app integrated various functions, including information browsing, PA monitoring and feedback, symptom reporting, and social interaction. Patients in the intervention group received three months of personalized online PA guidance in addition to routine care. The control group received routine care. Baseline and post-intervention investigations after three months were conducted in two groups using the Short Form of International Physical Activity Questionnaire, the Hospital Anxiety and Depression Scale, and the Functional Assessment of Cancer Therapy-Breast cancer.

Results

After three months of intervention, compared to the control group, breast cancer patients in the intervention group showed significant improvements in walking, moderate PA, and overall PA (P < 0.05). Compared to the baseline data, breast cancer patients in the intervention group had significant improvements in walking and overall PA after three months (P < 0.05), whereas the control group experienced significant declines in walking, moderate PA, and overall PA after three months (P < 0.05). There were statistically differences between the two groups in scores for anxiety, overall quality of life, and its dimensions, such as physical well-being, emotional well-being, and additional breast cancer well-being (P < 0.05).

Conclusions

The theory-based tailored mHealth PA intervention has demonstrated a positive impact on promoting PA behavior change and emotional management among breast cancer patients. The 'Breast Care' app integrated various practical behavior change strategies, offering valuable guidance for personalized remote rehabilitation support for cancer patients.

Investigation of screening questions to identify insomnia in cancer patients

The high prevalence of insomnia in cancer patients leads to a significant reduction in the quality of life of those affected. A detailed record of symptoms therefore plays an essential role for further course of treatment. Which screening instruments enable identification of cancer patients with insomnia is the subject of this single-arm nonrandomized study. During the data collection period, cancer patients meeting the following criteria: self-reported tiredness and/or trouble falling or staying asleep or sleeping too much in an electronic patient-reported outcome measurement were enrolled. For further analysis, focus was placed on the Patient Health Questionnaire Depression Scale (PHQ-8), the Minimal Documentation System (MIDOS2) and the Insomnia Severity Index (ISI). Frequency, correlation, and variance analyses were conducted to identify likely predictors of insomnia. Our findings indicate a closer correlation between the screening question pertaining to sleep disorders and the ISI, compared to the question on tiredness and the ISI. The initial recording of sleep-related parameters plays an essential role for cancer patients in order to identify and treat modifiable factors as promptly as possible. For an initial assessment, we recommend asking about trouble falling or staying asleep or sleeping too much.

Educating Nurses in Sleep Screening, Brief Intervention, and Referral for Treatment

BACKGROUND

Poor sleep is an unrecognized problem among cancer survivors that affects quality of life. However, screening for sleep disorders is not routine in cancer care. To fill this gap, a self-paced online training program was designed for RNs to screen patients for sleep disturbance and provide brief intervention or referral for treatment (Sleep-SBIRT).

METHOD

A three-phase evaluation pilot study included the following steps: (a) develop an online training program with in situ simulation; (b) implement the program with RNs at a comprehensive cancer center; and (c) evaluate module and quiz completion rates and focus group thematic analysis.

RESULTS

Of the 22 RNs participating, 17 completed online modules and in situ simulation. The RNs were satisfied (M = 4.74/5, SD = 0.42) and self-confident (M = 4.45/5, SD = 0.45) with the learning. Focus group themes were learning new knowledge, learning online effectively, applying learning to in situ simulation, and intending to implement.

CONCLUSION

The RNs gained knowledge applying Sleep-SBIRT, but future larger studies are warranted. [J Contin Educ Nurs. 2024;55(8):387-392.].

Exercise Intervention on Insomnia in Patients with a Cancer: A Systematic Review of the Literature

Cancer is associated with increased muscle weakness, reduced physical functioning, increased fatigue, but also sleep disturbances, including insomnia, that affect quality of life (QoL). Physical activity demonstrated benefits on functional capacity, resilience and cancer-related fatigue, but there is a paucity of available data regarding its effects on insomnia in patients with cancer. This systematic review aims to examine the efficacy of exercise levels with insomnia in cancer patients. A systematic search was performed for articles published in PubMed and Cochrane Library databases from December 2013 to February 2023. Included studies explored insomnia during or after cancer treatment, with various exercise interventions. The search identified nine studies included in this review. Due to substantial heterogeneity in the interventions across studies, meta-analysis was not performed. Three studies reported positive results for insomnia reduction by self-reported outcomes under a supervised aerobic exercise program alone or combined with strength training. The present systematic review establishes the role of exercise interventions for reducing cancer-related insomnia. Further studies are indeed warranted to improve the level of evidence for exercise interventions for implementation in the care of cancer-related insomnia.

The impact of symptom clusters on endocrine therapy adherence in patients with breast cancer

BACKGROUND

When taken as prescribed, endocrine therapy is effective in reducing risk of recurrence and mortality in the treatment of patients with breast cancer. However, treatment side effects can act as a barrier to medication adherence. Existing research has not identified any specific side effects as consistent predictors of nonadherence. Our aim was to explore the influence of symptom clusters on self-reported adherence in patients with breast cancer.

METHODS

A cross-sectional online survey was conducted, including patients with breast cancer currently or previously prescribed endocrine therapy (N = 1051). This included measures of self-reported endocrine therapy adherence and common symptoms among this population (insomnia, depression, anxiety, fatigue, musculoskeletal, and vasomotor symptoms).

RESULTS

Unintentional nonadherence was higher than intentional nonadherence (50.8 % vs 31.01 %). The most troublesome symptom was insomnia (73.83 % displayed probable insomnia disorder). K-means cluster analysis identified 2 symptom clusters: overall High symptoms, and overall Low symptoms. Participants in the Low symptoms cluster were significantly more likely to be classed as adherent based on unintentional and intentional items.

CONCLUSIONS

Nonadherence was high in the current sample, and significantly more likely in participants reporting overall severe symptoms. Clinicians should be aware of the scale of common side effects and facilitate open conversation about potential barriers to adherence. Follow-up care should include assessment of common symptoms and signpost patients to appropriate support or treatment when required. Future research should explore potential for a central symptom to act as a target for intervention, to relieve overall side effect burden and facilitate better medication adherence.

Sleep disturbance among breast cancer survivors and controls from midlife to early older adulthood: Pink SWAN

PURPOSE

To compare sleep disturbance from 5 years pre- to 5 years post-diagnosis between breast cancer survivors (BCS) and women without cancer over the same period and to identify BCS subgroups exhibiting different sleep trajectories.

METHODS

Analyses included data from 152 BCS and 2163 controls from 20 years of follow-up in the longitudinal Study of Women's Health Across the Nation (SWAN), a multi-racial/ethnic cohort study. SWAN participants were assessed approximately annually from 1995 to 2015 using a standardized protocol. Pink SWAN focused on women who reported no cancer at SWAN enrollment and developed incident breast cancer after enrollment or did not develop breast cancer. Nonparametric locally weighted scatterplot smoothing plots and linear mixed models were used to compare the prevalence of the most frequently reported sleep problem, frequently waking several times a night (a sleep maintenance problem) during the previous 2 weeks, between BCS and controls in the 5 years pre- to 5 years post-diagnosis. We characterized heterogeneity among BCS on this sleep problem using group-based trajectories and examined pre-diagnosis variables as predictors of group membership.

RESULTS

No differences were found between BCS and controls in prevalence of frequent nighttime awakenings either before or after diagnosis. Among BCS, three trajectory groups were identified. Thirty-seven percent of BCS had consistently low prevalence of waking several times per night, 30% had high prevalence, and 33% had increasing prevalence which started 2 years pre-diagnosis. Prevalence of pre-diagnosis vasomotor symptoms, anxiety, depressive symptoms, and smoking differed among these groups.

CONCLUSION

Among mid-aged women diagnosed with breast cancer, this diagnosis did not trigger/amplify a sleep maintenance problem. The majority of BCS had similar levels of this sleep problem from pre- to post-diagnosis.

IMPLICATIONS FOR CANCER SURVIVORS

Although sleep maintenance problems were not amplified by a cancer diagnosis, a subset of BCS may have sleep issues that should be monitored and treated, as indicated.

Global prevalence of poor sleep quality in cancer patients: A systematic review and meta-analysis

OBJECTIVE

Poor sleep quality is common in patients with cancer, but the prevalence rates varied widely across studies. This systematic review and meta-analysis examined the pooled prevalence of poor sleep quality among patients with cancer.

METHODS

Systematic literature searches were independently conducted in the major databases (Web of Science, PubMed, EMBASE and PsycINFO). Studies that reported the prevalence of poor sleep quality in patients with cancer were analyzed using a random effects model. Funnel plots and Egger's tests were used to assess publication bias. Statistical analyses were performed using R software.

RESULTS

A total of 59 epidemiological studies involving 16,223 patients were included. The pooled prevalence of poor sleep quality in patients with cancer was 57.4% [95% confidence interval (CI): 53.3% - 61.6%]. Additionally, three comparative studies with 372 patients and 412 healthy controls were included. Compared to healthy controls, patients with cancer had a significantly higher risk for poor sleep quality [odd ratio (OR) = 3.0; 95%CI: 1.2-7.2; P < 0.05]. Subgroup analyses of the studies revealed that studies from Middle East & North Africa region and low income countries, and on gynecological cancer as well as those with a lower cut-off value of sleep quality (all P < 0.01) reported a higher prevalence of poor sleep quality. Meta-regression analyses showed that higher prevalence of poor sleep quality was associated with higher prevalence of comorbid depression (P < 0.05) and anxiety (P < 0.01), but was associated with a lower education level (P < 0.05) and alcohol use ratio (P < 0.05).

CONCLUSION

Poor sleep quality is common among patients with cancer. Considering the overall high prevalence rate and negative impact of poor sleep quality, appropriate measures to identify and improve poor sleep quality are needed to enhance the clinical outcomes in this group.

Differential Characteristics of Fatigue-Pain-Sleep Disturbance-Depression Symptom Cluster and Influencing Factors of Patients With Advanced Cancer During Treatment: A Latent Class Analysis

BACKGROUND

Patients with advanced cancer may experience symptom clusters during treatment (eg, fatigue, pain, sleep disturbance, depression). Understanding the characteristics and factors associated with symptom cluster classes among this patient population is essential for effective symptom management.

OBJECTIVE

The aims of this study were to identify symptom cluster (fatigue-pain-sleep disturbance-depression) classes and explore influencing factors in patients with advanced cancer during the treatment.

METHODS

A cross-sectional survey was conducted in an oncology department of a tertiary hospital in China from September 2020 to March 2021. Cancer patients (stage III/IV) 18 years or older completed the questionnaires on pain, fatigue, sleep disturbance, depression, physical activity, and exercise self-efficacy. Latent class analysis and multinomial logistic regression were used.

RESULTS

Three hundred sixty-five patients who were male (65.2%) and younger than 60 years (59.5%) completed questionnaires. Three symptom cluster classes were identified: class 1 ("low symptom burden" class), class 2 ("fatigue-insomnia" class), and class 3 ("high symptom burden" class), with a percentage of 54.5%, 38.6%, and 6.8%, respectively. The quality-of-life score, introversion/extroversion, economic burden, Karnofsky Performance Status, albumin level, and exercise self-efficacy were significantly different among the 3 classes (P < .05).

CONCLUSION

Patients with advanced cancer were classified into 3 distinct classes, with class 1 having the best function. Results from this study reveal that Karnofsky Performance Status, albumin level, and exercise self-efficacy were significant factors for the latent classes of symptom cluster.

IMPLICATIONS FOR PRACTICE

Exercise self-efficacy is important for personalized interventions and improving symptom management efficiency.

Neurological mechanism and efficacy of acupuncture for breast cancer-related insomnia: a study protocol for randomized clinical trial

Background

Breast cancer survivors (BCSs) are at a higher risk of developing insomnia. The negative effects of cancer-related insomnia (CRI) include depression, anxiety, fatigue, aggressive pain, impaired immune functioning, decreased quality of life, and even increased cancer mortality. Although preliminary progress has been made in the treatment of CRI with acupuncture, the evidence is insufficient and the neurological mechanism underlying the effect of acupuncture is still unclear.

Methods

The study employs a single-blinded, randomized, controlled trial design. A total of 80 participants will be randomly allocated in a 1:1 ratio to either the treatment group (n = 40) or the control group (n = 40). The former will receive acupuncture treatment, while the latter will receive sham acupuncture treatment. Both groups will receive 12 sessions over a 4-week period, three times per week (every other day), and each session will last for 30 min. Follow-up assessments will be conducted in week 8. The primary outcome will be the treatment response rate. Secondary outcomes include the change in Insomnia Severity Index (ISI), the treatment remission rate, actigraphy sleep assessment, Generalized Anxiety Disorder Scale (GAD-7), Patient Health Questionnaire-9 (PHQ-9), Quality of Life Core Scale (QLQ-C30), the weekly usage of remedial drugs, and functional magnetic resonance imaging (fMRI) analysis. Data for the outcomes will be collected at week 0 (the baseline), week 1 (the intervention period), week 4 (the post-treatment period), and week 8 (the follow-up period).

Discussion

The objective of this study is to assess the efficacy of acupuncture for patients with CRI in comparison with sham acupuncture. Additionally, the research aims to explore the neuropathological mechanisms of CRI and provide the first evidence on the characteristics of acupuncture treatment using fMRI. We expect that the results of this study will provide valuable scientific evidence of acupuncture treatment for CRI.Clinical trial registration: Chinese Clinical Trial Registry, identifier ChiCTR2300070349: https://www.chictr.org.cn/showproj.html?proj=188677.

Efficacy of mind-body therapies for sleep disturbance in patients with early-stage cancer: A systematic review and network meta-analysis

OBJECTIVE

To evaluate and compare the efficacy of different mind-body therapies (MBTs) for sleep disturbance in patients with early-stage cancer.

METHODS

Randomised controlled trials that included patients (aged ≥18 years) with early stage cancer who underwent MBTs (mindfulness, hypnosis, relaxation, yoga, and qigong) were searched in the CINAHL via the EBSCO Host, Cochrane Library, Embase, MEDLINE, PsycINFO, PubMed, and Scopus databases, from the date of database inception to October 2022. The outcomes were subjective sleep disturbance and objective sleep efficiency. Network meta-analysis (NMA) and comparative effects ranking were performed using STATA (v14.0; STATACorp, College Station, TX, USA).

RESULTS

Forty-seven studies investigating five MBTs were included in the NMA. For cancer patients receiving active treatment, mindfulness demonstrated the largest effect size in reducing subjective sleep disturbance (standardised mean difference [SMD]: 0.85; 95% confidence intervals [CI]: 0.20-1.50; Grading of Recommendations Assessment, Development, and Evaluation assessment: moderate), and had the highest cumulative probability compared to usual care or waitlist. For cancer patients who had completed active treatment, qigong demonstrated the largest effect size in reducing subjective sleep disturbance (SMD: 0.99; 95% CI: 0.35-1.63; GRADE: low), followed by hypnosis (SMD: 0.87; 95% CI: 0.32-1.42; GRADE: moderate), and mindfulness (SMD: 0.42; 95% CI: 0.24-0.59; GRADE: moderate). Qigong also demonstrated the largest effect size in improving objective sleep efficiency (weighted mean differences: 10.76; 95% CI: 2.01-19.50; GRADE: low); however, the effect of qigong was tested in only one study in this NMA. Among the eight different treatment conditions, cognitive behavioral therapy (CBT) showed the highest cumulative probability (surface under the cumulative ranking curve: 96.3%) in reducing subjective sleep disturbance and the second highest cumulative probability (SUCRA: 83.3%) in improving objective sleep efficiency.

CONCLUSION

There is no evidence supporting the use of MBTs to replace or be comparable to CBT. Mindfulness can be recommended as an optional treatment for reducing sleep disturbance in patients with early-stage cancer. Some support was observed for qigong and hypnosis in reducing sleep disturbances in patients with early-stage cancer who had completed active treatment. More rigorous trials are warranted to confirm whether different forms of MBTs have different effects on sleep in patients with cancer.

Effect of online interventions on reducing anxiety and depression for women with breast cancer: a systematic review and network meta-analysis protocol

INTRODUCTION

Breast cancer has becoming the most common malignancy in women globally. Various online interventions have been conducted to help women with breast cancer to manage their psychological symptoms. However, there has been not yet a network meta-analysis that has synthesised scientific evidence about online intervention on reducing anxiety and depression for women with breast cancer. To fill the literature gap, this protocol aims to generate a systematic review and network meta-analysis to assess the effectiveness of online interventions on reducing anxiety and depression for these women with breast cancer. The study results may inform the recommendations for clinical guidelines and facilitate the decision-making process to improve psychological health of women with breast cancer.

METHODS AND ANALYSIS

The protocol is in compliance with the guideline of Preferred Reporting Items for Systematic Reviews and Meta-Analysis Protocols and for Systematic Reviews and Network Meta-Analysis. The electronic databases of Pubmed, EMBASE, CINAHL, PsycINFO, Web of Science, Cochrane Central Registry of Controlled Trials and OpenGrey will be used for searching of related randomised controlled trials from their inception. No restrictions on publication date and language will be applied. The primary outcomes are the symptoms of anxiety and depression, and the secondary outcome is the satisfaction with the received healthcare. Two reviewers independently evaluate the risk of bias using the Cochrane Collaboration's Risk of Bias tool. The assessment of heterogeneity, inconsistency, subgroup analysis, sensitivity analysis and publication bias will be conducted. The netmeta package of R software will be used to perform the network meta-analysis.

ETHICS AND DISSEMINATION

This study will be based on previous research findings, so that ethics approval is not required. Data searching commences in July 2023 and expects to complete in January, 2024. The findings will be disseminated through peer-reviewed journals and academic conferences.

Research on the applicability of an exercise rehabilitation app aiming to improve the mental and physical health of breast cancer patients in the post-operative period

Purpose

Breast cancer is one of the most common malignant cancers in women, seriously endangering the physical and mental health of patients. In this study, we developed an app for breast cancer patients undergoing radiotherapy or chemotherapy with a focus on exercise interventions, supplemented by nutritional and psychological interventions, to verify the applicability of the app for these patients and its impact on their quality of life, sleep, and psychological state. We also investigated the patients' experience and perceptions of the app.

Methods

A total of 17 participants, aged 42-58 years, were recruited for this study using a mixed-methods design, including quantitative group pre-and post-test scores and qualitative interview results. The participants used the app for 8-18 weeks depending on their radiotherapy or chemotherapy cycle. During the radiotherapy or chemotherapy period, the participants used the "Yun Dong Ru Kang" exercise rehabilitation app to perform aerobic exercises twice a week, as well as rehabilitation exercises appropriate to their radiotherapy or chemotherapy stage, and used the app on their own the rest of the time. The primary results included their scores on the PSSUQ overall assessment usability questionnaire, the users' use of the app, and the results of the interviews; the secondary indicators were quality of life, sleep status, and anxiety and depression status.

Results

An overall score of 6.2 (out of 7 points) on the PSSUQ questionnaire indicates the high usability; the average use time per subject per week was 97.69 ± 11.82 min, which exceeds the minimum use time, but the average use time tended to decrease as the use time was postponed. Promoted articles on nutritional diets received the most hits. The results of the interviews were consistent with the questionnaire scores, with the majority of participants believing that the means of exercise should be enriched and the interface optimized, while the reduction in the length of use was related to the participants' own state of learning about calisthenics. In the results of the Breast Cancer-Specific Scale FACT-B, there was a significant increase (p < 0.05) in the Emotional Status dimension score and a significant decrease (p < 0.05) on the Additional Concerns dimension score. In the results of the Pittsburgh Sleep Quality Inventory PSQI, there was a non-significant improvement in all items except for a significant increase (p < 0.05) for the Hypnotic Medication item. In the Hospital Anxiety and Depression Scale (HADS), there was no significant improvement in any of the anxiety and depression factors.

Conclusions

The "Yun Dong Ru Kang "app has certain applicability, and the use of the exercise rehabilitation app may effectively reduce the negative impact of chemotherapy side effects on the quality of life, sleep and depression of breast cancer patients in the chemotherapy or radiotherapy phase. Before it is put into use in the future, the app should be enriched with exercise tools, the interface should be optimized, and articles on nutrition and diet should be promoted.

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.

Construction of a cutoff and fusion model of breast cancer patients in family: a grounded theory study

PURPOSE

To construct a coping model for interactions between breast cancer patients and their families across the disease trajectory using the patients' voice, and to establish a mechanism for restoring family balance when faced with stresses related to breast cancer.

METHODS

This study employed a longitudinal qualitative study design using constructivist grounded theory. We divided breast cancer trajectory into four periods: suspicion, diagnosis, treatment, and rehabilitation. We then interviewed patients during each of these periods.

RESULTS

Twenty patients with breast cancer were interviewed. A cutoff and fusion model of the breast cancer patient's interactions with her family contained three coping themes: independence, coexistence, and interconversion. The coping trajectory of breast cancer patients in their families has specific themes in each period, such as anxiety, information, emotion, and experience.

CONCLUSION

We constructed a cutoff and fusion model of breast cancer patients' coping trajectory in their families. This model not only explains the opposite, coexistent, and interconvertible relationship between cutoff and fusion but also the specific challenges requiring cutoff and fusion during the four periods. Our findings highlight the dynamic balance of cutoff and fusion for patients' coping in their families.

IMPLICATIONS FOR PRACTICE

This model helps clinical staff understand the coping of breast cancer patients in their families. When providing family education, clinical staff should suggest that they not only provide support to the patient but give each other space as well.

Associations of accelerometer-measured physical activity, sedentary behavior with self-reported insomnia in older women: Does pattern matter?

AIMS

Insomnia is a common sleep disorder that widely occurs in older population, especially older women. This study aims to investigate the associations between accelerometer-measured physical activity (PA) and sedentary behavior (SB) patterns with insomnia in older Chinese women.

METHODS

Cross-sectional data derived from the baseline survey of the Physical Activity and Health in Older Women Study were analyzed for 1112 older women aged 60 to 70. Insomnia was evaluated using Athens Insomnia Scale. PA and SB patterns were measured through an accelerometer. Multivariate logistic regression was used to investigate associations of PA and SB patterns with insomnia.

RESULTS

All SB variables were positively associated with insomnia, with multivariate-adjusted ORs of 1.24, 1.19 and 1.19 for 60-min increase of total SB, 10min-bouted SB and 30min-bouted SB, respectively. Total LPA and bouted LPA were negatively associated with insomnia, with multivariate-adjusted ORs of 0.90 and 0.89 for 30-min increase of total LPA and bouted LPA, respectively.

CONCLUSION

Avoiding SB and encouraging LPA engagement may hold promise in preventing insomnia and promoting sleep in older population. Future studies with experimental study design and follow-up periods are warranted to illustrate the causal associations.

Insomnia among Cancer Patients in the Real World: Optimising Treatments and Tailored Therapies

BACKGROUND

Insomnia is commonly reported by cancer patients. Its multifaceted pathophysiology makes this symptom a complex challenge for the clinician, who should bear in mind the manifold world of causes and consequences of sleep disturbances in these patients and the importance of accurate treatment that should consider the frequent co-prescription of multiple medications. With our work, we aim to provide a tool to better master the treatment of this symptom in cancer patients, considering the gap between clinical and pharmacodynamic knowledge about the efficacy of different molecules and evidence-based prescribing.

METHODS

A narrative review of the studies investigating the pharmacological treatment of insomnia in cancer patients was conducted. Three hundred and seventy-six randomised controlled trials (RCTs), systematic reviews and meta-analyses were identified through PubMed. Only publications that investigated the efficacy of the pharmacological treatment of insomnia symptoms in cancer patient were considered.

RESULTS

Among the 376 publications that were individuated, fifteen studies were eligible for inclusion in the review and were described. Pharmacological treatments were outlined, with a broad look at specific clinical situations.

CONCLUSIONS

The management of insomnia in cancer patients should be personalised, as is already the case for the treatment of pain, taking into account both the pathophysiology and the other medical treatments prescribed to these patients.

The Effect of Vinyasa Yoga Practice on the Well-Being of Breast-Cancer Patients during COVID-19 Pandemic

BACKGROUND

Vinyasa yoga practice improves body fitness and potentially positively affects practitioners' well-being and health. Due to the diverse intensity of practice and positions customized to the practitioner's needs, it can also support cancer patients. Undertaking physical activity that has a potentially positive effect on well-being and health was particularly important during the self-isolation that followed the COVID-19 pandemic. The purpose of this study was to evaluate the impact of three-month mild and moderate intensity vinyasa yoga practice on breast-cancer patients' stress perception, self-confidence, and sleep quality during COVID-19 induced self-isolation.

METHODS

Female breast-cancer patients participated in twelve-weeks of online vinyasa practice during the COVID-19 induced self-isolation period. Meetings were held once a week, where 60-min vinyasa yoga sequences were followed by 15 min of relaxation. Patients completed pre- and post-intervention surveys to evaluate changes in the following outcomes: stress perception, self-confidence, and sleep quality. Forty-one female patients enrolled in the Vinyasa course completed the pre-intervention survey, while 13 attended all the meetings and completed the post-intervention survey.

RESULTS

The effect of the twelve-week yoga and relaxation practice significantly reduced sleep problems and stress of oncological patients. The participants also declared an improvement in their general well-being and self-acceptance.

CONCLUSION

Dynamic forms of yoga combined with mindfulness techniques can be applied to patients treated for oncological diseases. It contributes to improving their well-being. However, in-depth studies are needed to analyze the complexity of this effect.

The Experience of Mindfulness-Based Stress Reduction on Menopausal Symptoms, Sleep Disturbance, and Body Image among Patients with Breast Cancer-A Qualitative Study

BACKGROUND AND AIM

The objective was to decrease patient menopausal symptoms, sleep disturbance, and body image using a nonpharmacological therapy for cultivating key healthy lifestyle habits in patients with breast cancer.

MATERIALS AND METHODS

The participants were 26 women with breast cancer who had recently received structured mindfulness-based stress reduction (MBSR) training in a clinical trial. Focus groups and interviews were conducted, during which the participants were asked semistructured, open-ended questions regarding the experiences of MBSR.

RESULTS

The participants indicated that MBSR helped them to alleviate hot flashes and night sweats, and improve sleep quality and be more at ease with the external aspect of their body. On the other hand, during MBSR intervention in a group manner, the participants felt more psychological support and an outlet for sharing negative emotional experiences.

CONCLUSION

This study identified the short-term benefits associated with group-based MBSR for women with breast cancer. In addition, our research identified the difficulties of intervention measures and coping methods. The study described the benefits of MBSR for patients with breast cancer. The findings of this study will help nursing staff identify the main coping menopausal symptoms and control negative mental health.

Sleep disturbance is associated with perturbations in immune-inflammatory pathways in oncology outpatients undergoing chemotherapy

OBJECTIVE/BACKGROUND

Sleep disturbance is a common problem in patients receiving chemotherapy. Purpose was to evaluate for perturbations in immune-inflammatory pathways between oncology patients with low versus very high levels of sleep disturbance.

PATIENTS/METHODS

Sleep disturbance was evaluated using the General Sleep Disturbance Scale six times over two cycles of chemotherapy. Latent profile analysis was used to identify subgroups of patients with distinct sleep disturbance profiles. Pathway impact analyses were performed in two independent samples using gene expression data obtained from RNA sequencing (n = 198) and microarray (n = 162) technologies. Fisher's combined probability test was used to identify significantly perturbed pathways between Low versus Very High sleep disturbance classes.

RESULTS

In the RNA sequencing and microarray samples, 59.1% and 51.9% of patients were in the Very High sleep disturbance class, respectively. Thirteen perturbed pathways were related to immune-inflammatory mechanisms (i.e., endocytosis, phagosome, antigen processing and presentation, natural killer cell mediated cytotoxicity, cytokine-cytokine receptor interaction, apoptosis, neutrophil extracellular trap formation, nucleotide-binding and oligomerization domain-like receptor signaling, Th17 cell differentiation, intestinal immune network for immunoglobulin A production, T-cell receptor signaling, complement and coagulation cascades, and tumor necrosis factor signaling).

CONCLUSIONS

First study to identify perturbations in immune-inflammatory pathways associated with very high levels of sleep disturbance in oncology outpatients. Findings suggest that complex immune-inflammatory interactions underlie sleep disturbance.

Comparative efficacy and acceptability of interventions for insomnia in breast cancer patients: A protocol for systematic review and network meta-analysis

BACKGROUND

Symptoms of insomnia are highly prevalent in patients with breast cancer. There are a large number of pharmacological and non-pharmacological interventions that can be used for the management of insomnia in breast cancer patients; however, their comparative effectiveness and acceptability remain uncertain. This review aims to evaluate the efficacy and acceptability of different interventions for insomnia in breast cancer patients using a Bayesian network meta-analysis (NMA).

METHODS

We will perform a comprehensive literature search in PubMed, EMBASE, Cochrane Central Register of Controlled Trials (CENTRAL), Web of Science, and PsycINFO from inception to November 2022. We will include randomized controlled trials (RCTs) that compared the effects of different interventions on the management of insomnia in breast cancer patients. We will assess the risk of bias assessment using a modified Cochrane instrument. We will conduct a Bayesian random-effects framework NMA to estimate relative effects of interventional procedures. We will use Grading of Recommendations Assessment, Development and Evaluation to rate the certainty of evidence.

DISCUSSION

To our knowledge, this will be the first systematic review and network meta-analysis to compare the effectiveness and acceptability of all currently available interventions for insomnia in patients with breast cancer. The results of our review will help provide more evidence for the treatment of insomnia in breast cancer patients.

The association between sleep problems and general quality of life in cancer patients and in the general population

Objective

It is well-known that patients with cancer frequently experience sleep problems, and that sleep quality is associated with general quality of life (QoL). The aims of this study were to analyze the relationship between sleep problems and other components of QoL in more detail and to investigate sex and age differences in sleep quality in cancer patients in comparison with the general population.

Method

This study comprised one general population sample (n = 4,476) and eight samples with cancer patients (n between 323 and 4,020). Sleep Quality was measured using the QoL questionnaire EORTC QLQ-C30.

Results

All of the cancer patient groups reported more sleep problems than the general population. Sleep problems were associated with all facets of QoL both in cancer patients and in the general population. The highest associations were found in cancer patients for fatigue (r = 0.52) and emotional functioning (r = -0.47). The association between sleep quality and general QoL was lower in the cancer samples (r = -0.37) than in the general population (r = -0.46). Female cancer patients reported markedly more sleep problems than male patients did (d = 0.45), while this sex difference was lower in the general population (d = 0.15). In contrast to the general population, younger cancer patients had greater trouble sleeping than older patients did (d = -0.17).

Conclusion

The results underline the significance of the role mental factors play in sleep problems. Health care providers should pay special attention to female patients and younger patients concerning this issue.

Quality of Life of Chilean Breast Cancer Survivors: Multicentric Study

Introduction: As breast cancer survivorship rates increase, so does the necessity to improve survivors’ health-related quality of life (HRQoL). Objective: To analyze HRQoL among Chilean breast cancer survivors, in general and considering geographic location. In addition, to correlate HRQoL with age, education level and body mass index (BMI). Method: Cross-sectional observational study which included 125 female breast cancer survivors from three public hospitals in three Chilean Macroregions: Central, North Central, and South. The EORTC Questionnaires, QLQ-C30 and QLQ-BR23, and sociodemographic and clinical records were applied. Results: The mean age was 56.1 (±11.9) years with a HRQoL summary score of 67.6 (21.9). HRQoL was reduced mainly in emotional functioning, pain, and insomnia. Fatigue, dyspnea, appetite loss, constipation, financial difficulties, breast and arm symptoms were also reported. The women from the South Macroregion Hospital presented the worst HRQoL scores for most of the domains [general health, functioning (physical, emotional, cognitive and social), fatigue, and nausea], p<0.001. The summary score of HRQoL was correlated to age (Spearman´s rho=0.202, p=0.033), BMI (rho=-0.341, p<0.001), and education level (rho=0.310, p=0.001). Conclusion: Women from three Macroregions showed differences in HRQoL. The latter correlated to age, BMI, and education level. Considering the high presence of symptoms, it is necessary to improve survivorship care plans, providing access to rehabilitation in the continuum of care.

Sleep reactivity predicts insomnia in patients diagnosed with breast cancer

STUDY OBJECTIVES

To examine the role of sleep reactivity as a predictor of insomnia in patients diagnosed with breast cancer.

METHODS

A total of 173 women with breast cancer participated and were followed up over a period of 9 months. At baseline, participants were assigned to a high (n = 114) or low (n = 59) sleep reactivity group, based on their responses to the Ford Insomnia Response to Stress Test (FIRST). We assessed whether these FIRST groupings (high/low sleep reactivity) predicted changes in insomnia over time using the Insomnia Severity Index. We also tested if these FIRST groupings predicted insomnia disorder (using Insomnia Severity Index cutoffs) at 3 different time points (T3, T6, and T9).

RESULTS

Individuals with high sleep reactivity were more likely to experience a worsening of insomnia. Using logistic regression, we also found that FIRST grouping predicted insomnia disorder. Results remained significant after controlling for estimated premorbid sleep, age, and whether someone had chemotherapy.

CONCLUSIONS

Our study shows that sleep reactivity may be a robust predictor of insomnia within breast cancer populations. Sleep reactivity should be considered in routine clinical assessments as a reliable way to identify patients at risk of developing insomnia. This would facilitate early sleep intervention for those patients who are considered high risk.

Acupuncture for insomnia in people with cancer

This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To assess the effects of acupuncture therapy for insomnia in people with cancer, during and after active anti‐cancer treatment. 

We will evaluate the effects at different periods of treatment in relation to cancer treatment (before, during, or after treatment), and analyse the effects of acupuncture on quality of life.

Cognitive behavioural therapy for insomnia in people with cancer

This is a protocol for a Cochrane Review (intervention). The objectives are as follows:

To assess the effects of cognitive behavioural therapy (CBT) for insomnia in people with cancer. 

We will evaluate the effects at different periods of the cancer treatment (before, during, or after treatment), and analyse the effects of CBT on quality of life.

Psycho-oncology interventions focusing on fatigue and sleep disturbances

PURPOSE OF REVIEW

Cancer-related fatigue (CRF) and sleep disturbances are common symptoms among patients with cancer. They are often conceptualized as a part of a larger symptom cluster, also comprising pain and emotional distress. Despite their prevalence and long-lasting effects, CRF and sleep disturbances are still poorly addressed in clinical settings. Specific interventions are needed to manage these symptoms.

RECENT FINDINGS

In addition to conventional pharmacological therapies, other kinds of interventions are increasingly being developed in oncology. This review will discuss three categories of interventions for patients with cancer and their interest in alleviating CRF and sleep disturbances: physical exercises (e.g., aerobic, resistance training, running, free weights), psychological interventions (e.g., cognitive-behavioural therapy, psychoeducational interventions), and mind-body interventions (e.g., yoga, mindfulness, hypnosis). The multicomponent aspect of these interventions seems particularly important to address these symptoms.

SUMMARY

The findings detailed in this review will allow the scientific community, as well as health professionals working in oncology settings, to be informed about new nonpharmacological therapeutic options to help patients to manage their symptoms. It could eventually help to improve existing interventions for these patients.

Effect of internet-delivered cognitive behavioral therapy on insomnia in convalescent patients with COVID-19: Protocol for a systematic review and meta-analysis

Introduction

Coronavirus Disease 2019 (COVID-19) has made a serious public health threat worldwide. Recent evidence has indicated that COVID-19 patients in convalescence frequently experience insomnia, which reduces their quality of life and causes unknown risks. The positive effect of cognitive behavior on insomnia has been well addressed in previous studies. Given the high infectivity and epidemicity of COVID-19, Internet-delivered intervention may be safer than face-to-face treatment. However, whether Internet-delivered cognitive behavioral therapy can effectively improve the insomnia of COVID-19 patients in convalescence has not been completely determined yet. Therefore, we conducted a meta-analysis and systematic review to evaluate the effects of Internet-delivered cognitive behavioral therapy on insomnia in COVID-19 patients in convalescence, with the aim to confer some guidance for its clinical application.

Methods and analysis

This systematic review and meta-analysis has been registered in the International Prospective Register of Systematic Reviews (PROSPERO). Two researchers will retrieve the relevant literature on Internet-delivered cognitive behavioral therapy for insomnia in convalescent patients with COVID-19 in PubMed, Web of Science, Embase, MEDLINE, Cochrane Library, Clinical Trials gov, Chinese Biomedical Literature Database (CBM), and Chinese National Knowledge Infrastructure (CNKI) from inception to 11th of December. In addition, we will review the relevant trials and references of the included literature and manually searched the grey literature. The two researchers will independently extracted data and information and evaluated the quality of the included literature. The Review Manager software (version 5.3) and Stata software (version 14.0) will be used for data analysis. The mean difference or the standardized mean difference of 95% CI will be used to calculate continuous variables to synthesize the data. In addition, I² and Cochrane will be used for heterogeneity assessment.

Psychological Impact of Type of Breast Cancer Surgery: A National Cohort Study

Background

The present study assessed the impact of different types of breast surgery on rates of psychological disorders in breast cancer patients.

Methods

This nationwide cohort study, based on Korean Health Insurance Review and Assessment Service claims data, included 26,259 breast patients who underwent surgery from June 1, 2017, to December 31, 2018. Associations between the incidence of psychological disorders and variables were evaluated by time dependent Cox regression analyses.

Results

Of the 26,259 patients, 9394 (35.8%) underwent total mastectomy (TM) and 16,865 (64.2%) underwent partial mastectomy (PM); of the former, 4056 (43.2%) underwent breast reconstruction surgery (RS). A total of 4685 patients (17.84%) were newly diagnosed with psychological disorders after surgery. Multivariable analysis showed that axillary lymph node dissection was significantly associated with increased rates of overall psychological disorders (p < 0.0001), depression (p = 0.0462), anxiety (p < 0.0001) and insomnia (p < 0.0001). The rates of overall psychological disorders (p = 0.0002) and insomnia (p = 0.01) were significantly lower in patients who underwent TM than PM. RS tended to associated with reduced rates of overall psychological disorders in patients who underwent TM. Subgroup analysis showed that, compared with PM, RS after TM significantly associated with a reduced incidence of overall psychological disorders and insomnia in younger patients (< 50 years) and those who underwent sentinel lymph node biopsy.

Conclusion

In contrast to general belief, rates of overall psychological disorders and insomnia were lower in patients who underwent TM than PM. Moreover, RS after TM confers psychological benefit in younger patients with early stage breast cancer compared with PM.

Breast Cancer Survivors' Lived Experience of Adjuvant Hormone Therapy: A Thematic Analysis of Medication Side Effects and Their Impact on Adherence

Objectives

Side effects from Hormone Therapy (HT) impact medication adherence in breast cancer survivors. Understanding the most distressing HT side effects and their impacts may inform the development and implementation of interventions to alleviate these side effects and maximise HT adherence. This study aimed to explore the lived experience of adjuvant HT and understand the impact of HT side effects on adherence in a sample of breast cancer survivors.

Methods

Twenty-five female breast cancer survivors who were currently taking adjuvant HT participated in the study. One-to-one, online, semi-structured interviews were conducted to explore (i) specific side effects from HT and (ii) the impact of these side effects on HT adherence. Data were analysed using Thematic Analysis.

Results

The most commonly reported side effects were sleep disturbance, hot flashes, anxiety, and joint pain. Data exploring the impacts of these side effects on HT adherence were thematically synthesised into four analytical themes: "A bitter pill to swallow," "Seeking relief," "Taking control," and "The only way out is through." These themes encompass 14 sub-themes that encapsulate participants' daily struggle with HT side effects and the coping strategies developed to manage these.

Conclusion

Adverse side effects from HT, such as sleep disturbance, hot flashes, pain and anxiety, impair quality of life and increase the likelihood of participants' becoming non-adherent to HT medication. In order to maximise HT adherence and reduce breast cancer mortality, HT side effects should be closely monitored to identify individuals who would benefit from targetted intervention strategies aimed at alleviating these side effects.
