Sleep management training for cancer patients with insomnia

Is poor sleep quality associated with poor neurocognitive outcome in cancer survivors? A systematic review

PURPOSE

Cancer-related neurocognitive impairment and poor sleep are prevalent in cancer survivors and have a negative impact on their quality of life. This systematic review studies the association between sleep disturbance and neurocognitive functioning, as well as the potential positive effects of sleep interventions on neurocognitive functioning in cancer survivors. In addition, we aimed at determining the potential positive effects of sleep interventions on neurocognitive functioning in this population.

METHODS

Following PRISMA guidelines for reporting systematic reviews and meta-analyses, a comprehensive PubMed, Embase, PsycINFO, and CINAHL search was performed. Inclusion criteria were adult cancer survivors, self-reported or objective measures of neurocognitive functioning and sleep quality, or reports on the association between sleep and neurocognitive functioning.

RESULTS

Of the 4,547 records retrieved, 17 studies were retained for this review. Twelve studies were correlational, and five reported on interventions aimed at improving sleep quality. All studies that included self-reported neurocognitive functioning found that poorer sleep was associated with worse neurocognitive functioning. In four out of eight studies, poorer sleep was associated with objective neurocognitive impairment. Three out of five interventional studies showed neurocognitive functioning improved with improved sleep.

CONCLUSIONS

While poor sleep in cancer survivors is associated with self-reported neurocognitive impairment, the association between poor sleep and objective neurocognitive impairment is less evident.

IMPLICATIONS FOR CANCER SURVIVORS

It is important that care providers are aware of the association between sleep and neurocognitive functioning and that improving sleep quality can be a way to decrease neurocognitive impairment in cancer survivors.

Psychological Aspects of Breast Cancer

Breast cancer is the most commonly diagnosed cancer in women. Associated psychological symptoms include stress, adjustment difficulties, anxiety, depression, impaired cognitive function, sleep disturbances, altered body image, sexual dysfunction, and diminished overall well-being. Distress screening and assessment identifies women who will benefit from therapeutic interventions. Addressing these symptoms improves compliance with treatment and outcomes including disease-related outcomes, psychological symptoms, and quality of life. The most effective treatments include teaching coping skills such as expressing emotion, along with other structured cognitive behavioral, interpersonal, and mindfulness approaches. Patients should be provided these psychosocial supports throughout their cancer journey.

Kidney Cancer Integrative Oncology: Possible Options for Care

PURPOSE OF REVIEW

This study aims to review how complementary and integrative medicine (CIM), defined as therapies utilizing nutrition, physical activity, herbs, supplements, mind-body therapies, homeopathy, and other non-traditional therapies, can address the prevention, treatment, side effects, and recurrence of kidney cancer. This review discusses advances and discoveries in research, gaps in research, current debates on the subject, and directions for future research. We queried Ovid MEDLINE and PubMed databases using the search terms kidney cancer, integrative medicine, integrative oncology, nutrition, supplements, treatment, prevention, and therapy. Searches were limited to integrative medicine and integrative oncology. We reviewed CIM therapies related to prevention, treatment, side effect mitigation, and recurrence of kidney cancers.

RECENT FINDINGS

Search results yielded 211 studies, of which 87 were relevant to this review. Studies related to CIM and kidney cancer were clustered into themes, including nutrition, physical activity, supplements, mind-body therapies, and alternative therapies. This review provides a foundation for utilizing the principles of integrative medicine in the prevention of and care for patients with kidney cancer and the need for further focused research on the effectiveness of CIM in kidney cancers.

Understanding Sleep Disturbances in Prostate Cancer-A Scientometric Analysis of Sleep Assessment, Aetiology, and Its Impact on Quality of Life

Prostate cancer is the most commonly diagnosed cancer in the United Kingdom. While androgen-deprivation therapy is the most common treatment for prostate cancer, patients undergoing this treatment typically experience side effects in terms of sleep disturbances. However, the relation between prostate cancer and sleep and the way in which sleep interventions may benefit oncological patients is underinvestigated in the literature. The current study aims to review in a data-driven approach the existing literature on the field of prostate cancer and sleep to identify impactful documents and major thematic domains. To do so, a sample of 1547 documents was downloaded from Scopus, and a document co-citation analysis was conducted on CiteSpace software. In the literature, 12 main research domains were identified as well as 26 impactful documents. Research domains were examined regarding the link between prostate cancer and sleep, by taking into account variations in hormonal levels. A major gap in the literature was identified in the lack of use of objective assessment of sleep quality in patients with prostate cancer.

Being a Cancer Patient during the Time of COVID-19: Impact of the Pandemic on the Anxiety and the Sleeping Quality of Oncology Patients

Objective

In this study, we aimed to assess anxiety and sleep quality in cancer patients treated or followed up at our clinic at the time of the outbreak of the COVID-19 pandemic.

Methods

Seven hundred and sixty-one patients who were either treated or followed up at our oncology clinic between April 2020 and May 2020 were included. Patients were assessed with the State-Trait Anxiety Inventory (STAI) and the Pittsburgh Sleep Quality Index (PSQI).

Results

Mean scores of the 761 participants were STAI, 43.45 ± 9.34 (range, 23–75), and PSQI, 5.67 ± 4.24 (range, 0–19). Quality of sleep was found bad in 447 (58.7%) (global score ≥5). Univariate analyses demonstrated statistical differences by stage of cancer, status of treatment, subgroup of treatment, monthly income, and levels of education in anxiety and sleep quality levels. Multivariate analyses showed active treatment (OR: 21.4; 95% CI: 9.08–50.4; p < 0.001) as the major independent variable that affected sleep quality; the major independent variable associated with anxiety was low income (OR: 4.43; 95% CI: 1.69–11.5; p = 0.002).

Conclusion

Anxiety and sleep quality levels were found comparable to pre-pandemic reports, and the pandemic was not observed to have additional negative impact on cancer patients. Also, universal basal anxiety and sleep disorder that accompany cancer or active treatment were observed in our study. The accurate effects of the pandemic can be analyzed in further studies using repeated data obtained from the same patient group.

Sleep Disorders in Cancer-A Systematic Review

INTRODUCTION

Sleep disorders, especially insomnia, are very common in different kinds of cancers, but their prevalence and incidence are not well-known. Disturbed sleep in cancer is caused by different reasons and usually appears as a comorbid disorder to different somatic and psychiatric diagnoses, psychological disturbances and treatment methods. There can be many different predictors for sleep disturbances in these vulnerable groups, such as pre-existing sleep disorders, caused by the mental status in cancer or as side effect of the cancer treatment.

METHODS

A systematic literature review of 8073 studies was conducted on the topic of sleep and sleep disorders in cancer patients. The articles were identified though PubMed, PsycInfo and Web of Knowledge, and a total number of 89 publications were qualified for analysis.

RESULTS

The identified eighty-nine studies were analyzed on the topic of sleep and sleep disorders in cancer, twenty-six studies on sleep and fatigue in cancer and sixty-one studies on the topic of sleep disorders in cancer. The prevalence of sleep disturbences and/or sleep disorders in cancer was up to 95%.

DISCUSSION

Sleep disturbances and sleep disorders (such as insomnia, OSAS, narcolepsy and RLS; REM-SBD) in cancer patients can be associated with different conditions. Side effects of cancer treatment and cancer-related psychological dysfunctions can be instigated by sleep disturbances and sleep disorders in these patients, especially insomnia and OSAS are common. An evidence-based treatment is necessary for concomitant mental and/or physical states.

The Effects of Progressive Relaxation Exercises following Lumbar Surgery: A Randomized Controlled Trial

BACKGROUND AND AIM

This study aimed to examine the effect of progressive relaxation exercises on anxiety, pain, and sleep quality among patients who underwent surgery for lumbar disc hernia.

MATERIALS AND METHODS

This randomized, non-blinded, parallel-group clinical trial was conducted with 97 patients who had a lumbar microdiscectomy. On the first, second, and third day of the postoperative period, routine nursing care was performed on the control group, while additional progressive relation exercises were performed on the experimental group.

RESULTS

When the experimental and control groups were compared regarding SAI, VAS-P, and VAS-S scores before the surgery, no differences were found (p > 0.05); however, there were significant differences in the scores obtained on the mornings of the second and third days after the surgery (p < 0.05).

CONCLUSIONS

Progressive relation exercises used as a supportive nursing intervention were found to reduce pain and anxiety and increase sleep quality.

Sleep problems in advanced cancer patients and their caregivers: Who is disturbing whom?

Background The aims of the study were to understand sleep problems and their effects in advanced cancer patients and spousal and intimate partner caregivers and to examine the directionality of the link between patients' and caregivers' sleep problems. Methods Fifty-four advanced cancer patients and their spousal and intimate partners were administered a battery of questionnaires that included the Pittsburgh Sleep Quality Index and the Center for Epidemiological Studies at the patients' cancer diagnosis and at 2, 4, and 6 months after diagnosis. Results Patients' and caregivers' sleep duration was significantly related. Using cross-lagged panel analyses, caregivers' sleep quality significantly predicted patients' sleep quality and patients' sleep quality subsequently predicted caregivers' sleep quality. Patients' sleep latency significantly was found to significantly predict caregivers' sleep latency. Conclusion Patients diagnosed with cancer and their intimate partners have poor sleep quality and sleep patterns are related.

Effects of acupuncture versus cognitive behavioral therapy on cognitive function in cancer survivors with insomnia: A secondary analysis of a randomized clinical trial

BACKGROUND

Cancer-related cognitive impairment is a prevalent, disruptive condition potentially exacerbated by sleep disturbances. The current study was performed to evaluate the effects of acupuncture versus cognitive behavioral therapy for insomnia (CBT-I) on objective and subjective cognitive function in cancer survivors with insomnia.

METHODS

Using data from a randomized clinical trial (160 survivors) that compared acupuncture versus CBT-I for insomnia occurring in cancer survivors, the authors analyzed cognitive outcomes and their relationship to insomnia symptoms. Analysis was limited to 99 patients who reported baseline cognitive difficulties. Interventions were delivered over 8 weeks. Objective attention, learning, and memory were evaluated using the Buschke Selective Reminding Test. Subjective cognitive function was assessed using the Brown Attention-Deficit Disorder Scales. Insomnia symptoms were assessed using the Insomnia Severity Index. All outcomes were collected at baseline, week 8, and week 20.

RESULTS

From baseline to week 8, acupuncture produced statistically significant within-group improvements in objective attention (Cohen D, 0.29), learning (Cohen D, 0.31), and memory (Cohen D, 0.33) that persisted to week 20 (all P < .05), whereas CBT-I produced a statistically significant within-group improvement in objective attention from baseline to week 20 (Cohen D, 0.50; P < .05); between-group differences were not statistically significant. Both interventions produced statistically significant within-group improvements in subjective cognitive function at weeks 8 and 20 compared with baseline (all P < .001); between-group differences were not statistically significant. In the acupuncture group, patients with clinically meaningful responses with regard to insomnia symptoms demonstrated a significantly greater improvement in subjective cognitive function compared with those without clinically meaningful insomnia responses (P = .006).

CONCLUSIONS

Among cancer survivors with insomnia, both acupuncture and CBT-I produced significant improvements in objective and subjective cognitive function. However, the effect sizes varied and only survivors in the acupuncture group demonstrated a significant relationship between cognitive and sleep outcomes. These preliminary findings warrant further investigation to guide the personalized management of patients with cancer-related cognitive impairment.

The effect of relaxation exercises on sleep quality in pregnant women in the third trimester: A randomized controlled trial

OBJECTIVE

To assess the effects of relaxation exercises on subjective sleep quality of in third-trimester pregnant women.

MATERIALS AND METHODS

The pretest posttest randomized controlled trial recruited 84 pregnant women in the third trimester. Following random assignment of subjects, the treatment group (n = 46) performed relaxation exercises for four weeks and the control group (n = 46) received standart cares. At baseline and after the intervention sleep quality was assessed. Data obtained were analyzed in SPSS.

RESULTS

The mean score of the global Pittsburgh Sleep Quality Index was 7.12 ± 3.66. It was determined that relaxation exercises improved some sleep quality subscales including subjective sleep quality, sleep latency, sleep duration and habitual sleep efficiency, sleep disturbances, daytime dysfunction and global sleep quality. The difference between the two groups was found to be statistically significant (p < 0.05).

CONCLUSION

A four -week compact disc guide relaxation exercises program can be effective in improving sleep quality.

An Integrative Review of Nonpharmacological Interventions to Improve Sleep among Adults with Advanced Serious Illness

BACKGROUND

Sleep fragmentation is common among those with advanced serious illness. Nonpharmacological interventions to improve sleep have few, if any, adverse effects and are often underutilized in these settings.

OBJECTIVE

We aimed to summarize the literature related to nonpharmacological interventions to improve sleep among adults with advanced serious illness.

METHODS

We systematically searched six electronic databases for literature reporting sleep outcomes associated with nonpharmacological interventions that included participants with advanced serious illness during the period of 1996-2016.

RESULTS

From a total of 2731 results, 42 studies met the inclusion criteria. A total of 31 individual interventions were identified, each evaluated individually and some in combination with other interventions. Twelve of these studies employed either multiple interventions within an intervention category (n = 8) or a multicomponent intervention consisting of interventions from two or more categories (n = 5). The following intervention categories emerged: sleep hygiene (1), environmental (6), physical activity (4), complementary health practices (11), and mind-body practices (13). Of the 42 studies, 22 demonstrated a statistically significant, positive impact on sleep and represented each of the categories. The quality of the studies varied considerably, with 17 studies classified as strong, 17 as moderate, and 8 as weak.

CONCLUSIONS

Several interventions have been demonstrated to improve sleep in these patients. However, the small number of studies and wide variation of individual interventions within each category limit the generalizability of findings. Further studies are needed to assess interventions and determine effectiveness and acceptability.

Cognitive Behavioral Therapy for Insomnia, Mindfulness, and Yoga in Patients With Breast Cancer with Sleep Disturbance: A Literature Review

The number of patients with breast cancer diagnosed with sleep disturbance has grown substantially within the United States over the past 20 years. Meanwhile, there have been significant improvements in the psychological treatment of sleep disturbance in patients with breast cancer. More specifically, cognitive behavioral therapy for insomnia (CBT-I), mindfulness, and yoga have shown to be 3 promising treatments with varying degrees of benefit, supporting data, and inherent limitations. In this article, we will outline the treatment approach for sleep disturbance in patients with breast cancer and conduct a comprehensive review of CBT-I, mindfulness, and yoga as they pertain to this patient population.

The Effect of Progressive Relaxation Exercises on Fatigue and Sleep Quality in Individuals With COPD

This randomized controlled experimental study was conducted to investigate the effect of progressive muscle relaxation exercises on dyspnea, fatigue, and sleep quality in individuals with chronic obstructive pulmonary disease. A Descriptive Questionnaire and the Chronic Obstructive Pulmonary Disease and Asthma Fatigue Scale, Chronic Obstructive Pulmonary Disease and Asthma Sleep Scale and Medical Research Council Dyspnea Scale were used for data collection. The decrease in the mean dyspnea, fatigue, and sleep scores in the intervention group was statistically significantly more pronounced than the patients in the control group (P < .05). Progressive relaxation exercises can be implemented to decrease the dyspnea, fatigue, and sleep problems seen in patients with moderate and advanced chronic obstructive pulmonary disease by nurses working in the clinic.

Effect of nursing care given at home on the quality of life of patients with stomach cancer and their family caregivers' nursing care

In Turkey, the high incidences of stomach and oesophageal cancers in East and high incidence of stomach cancer in Northeast regions are remarkable. This study was conducted to identify homecare needs of patients with stomach cancer and their caregivers and the effect of family supportive nursing care on the quality of life of patients and families. The patient and his/her caregiver were assessed with respect to their daily life activities and NANDA was used for the identified nursing diagnoses, NIC for the appropriate interventions and NOC for assessment of the results. This study was conducted in a pre-test, post-test, controlled trial model to identify. The sample of the investigation consisted of 72 patients and 72 caregivers. As a data-collecting instrument, the Quality of Life Scale and Caregiver Quality of Life Index-Cancer were used. The overall quality of life, global health status and emotional and cognitive functions of the patients in the experimental group improved after the interventions. The overall quality of life and global health status was found to be poorer in the control group patients at post-test as compared to pre-test and their physical, role and social functions deteriorated. The caregivers' quality of life in the control group was affected more negatively with respect to the "Disruption in Daily Life" subscale as compared to pre-test values.

Psychiatric Symptoms and Psychosocial Problems in Patients with Breast Cancer

Cancer is a physical disease and also one of the leading clinical manifestations where psychosocial problems are prevalent. Psychosocial problems that these patients may have in the long run include anxiety, uneasiness, mourning, helplessness, fatigue, impairment of concentration, sleep disorders, mental and cognitive reservation, sexual dysfunction, infertility, psychological distress, and psychiatric disorders. Psychosocial problems have a nature of underpinning the emergence of psychological troubles. The prevalence of psychological disorders in patients with cancer range from 29% to 47%. Psychiatric disorders that are likely to be seen are severe stress disorder, adjustment disorder, depressive disorder, and other neurotic disorders. It is considered by the present author that in the event of breast cancer, potential psychiatric disorders may affect prognosis of the disease, adherance to and success of therapy, social and societal functioning, and survival rate. This paper aims to review the psychiatric symptoms and diseases that may develop in patients with breast cancer, which is one of the most frequent types of a globally common disease; i.e., cancer, as well as the impact of psychiatric symptoms on the treatment of disease.

Long-Term Effects of Two Formats of Cognitive Behavioral Therapy for Insomnia Comorbid with Breast Cancer

STUDY OBJECTIVES

The goal of this randomized controlled trial, conducted in breast cancer patients, was to assess the long-term efficacy of a video-based cognitive behavioral therapy for insomnia (VCBT-I), as compared to a professionally administered intervention (PCBT-I) and to a no-treatment group (CTL). An earlier report revealed that, at posttreatment, VCBT-I patients showed significantly greater sleep improvements than CTL, but that PCBT-I produced superior effects than VCBT-I on some sleep and secondary outcomes. In this report, long-term effects are compared.

METHODS

Two hundred forty-two women with breast cancer and with insomnia symptoms or using hypnotic medications participated to this three-arm randomized controlled trial: (1) PCBT-I (n = 81); (2) VCBT-I (n = 80); or (3) no treatment (CTL; n = 81) group. PCBT-I was composed of six weekly, individual sessions of approximately 50 min, whereas VCBT-I comprised a 60-min animated video and six booklets.

RESULTS

Study measures (sleep and secondary variables) were administered at pretreatment and posttreatment, and at a 3-, 6-, and 12-mo follow-up. Treatment gains were well sustained at follow-up in both PCBT-I and VCBT-I. As at posttreatment, the remission rate of insomnia at follow-up was greater in PCBT-I than in VCBT-I, which was greater than in CTL.

CONCLUSIONS

Although face-to-face therapy remains the optimal format to efficaciously administer CBT for insomnia in cancer patients, a minimal intervention, such as the video-based intervention tested in this study, produces significant and sustainable treatment effects.

Comorbid insomnia and cognitive behavior therapy

Insomnia most commonly presents comorbidly in association with medical and psychiatric disorders. Comorbid insomnia, however, remains under treated in the majority of patients. Concerns about drug interactions, adverse events, and dependence as well as the assumption that treating the insomnia as a secondary presentation that will resolve when the primary condition improves are all factors that contribute to the under treatment of comorbid insomnia. This article presents the growing research evidence that highlights the benefits and importance of targeting the insomnia that presents comorbidly with medical and psychiatric conditions utilizing the nonpharmacological and effective treatment of cognitive behavior therapy.

A pilot trial of brief group cognitive-behavioral treatment for insomnia in an adult cancer survivorship program

BACKGROUND

Cognitive-behavioral therapy for insomnia (CBT-Insomnia) is effective, yet rarely available for cancer survivors. This is unfortunate because survivors are at elevated risk for insomnia, which is associated with significant health consequences in this already at-risk population. Barriers to delivering CBT-Insomnia in oncology settings include a lack of trained providers, distance to cancer centers, and treatment duration.

PURPOSE

To address insomnia treatment barriers, we adapted standard CBT-Insomnia treatment and evaluated a pilot group-based approach for feasibility and efficacy in an adult cancer survivorship program.

METHODS

Thirty-eight cancer survivors (mean age = 52.2 years) enrolled in our three-session program delivered over 1 month. They were primarily diagnosed with breast cancer (58.6%) and were an average of 6.0 years post-diagnosis and 3.6 years post-treatment. Participants completed sleep logs throughout the study and measures of sleep at baseline and week 4.

RESULTS

Participants reported experiencing insomnia symptoms an average of 2.4 years, with 89.7% indicating that the cancer experience had caused/exacerbated symptoms. Significant pre/post-intervention group improvements in sleep efficiency (77.3% to 88.5%), sleep quality, and insomnia symptoms were reported (all ps < .01). Less than 1 in 3 had discussed insomnia symptoms with their oncology providers in the prior year.

CONCLUSIONS

Pilot data indicate that a brief, group-based CBT-Insomnia intervention in a survivorship setting is both feasible and efficacious. There is a need to increase awareness about insomnia and its treatment among both cancer survivors and oncology providers. If validated in future studies, this novel approach can improve cancer survivors' access to much needed insomnia treatment. Copyright © 2016 John Wiley & Sons, Ltd.

Evaluation of sleep disorders in cancer patients based on Pittsburgh Sleep Quality Index

Insomnia, poor sleep quality and short sleep durations are the most common problems seen in cancer patients. More studies are needed about sleep disorders in cancer patients. In our study, we aimed to investigate the prevalence of sleep disorders and the impact of these problems on the quality of life in cancer patients. Pittsburgh Sleep Quality Index (PSQI) was given to a total of 314 patients. The psychometric evaluation of the Turkish version of PSQI in cancer patients revealed that 127 (40.4%) patients had global PSQI scores >5, indicating poor sleep quality. There was no statistically significant relationship between PSQI scores and sexuality, marital status, cancer stage and chemotherapy type (P > 0.05); while the patients with bone and visceral metastasis had much lower PSQI scores (P = 0.006). Patients with Eastern Cooperative Oncology Group performance scores of 3 or more had also significantly lower PSQI scores (P = 0.02). In conclusion, PSQI questionnaire may be used to evaluate the sleep disorders in cancer patients. Consistent use of multi-item measures such as PSQI with established reliability and validity would improve our understanding of difficulties experienced by cancer patients with chronic insomnia.

Systematic review of sleep disorders in cancer patients: can the prevalence of sleep disorders be ascertained?

Although sleep is vital to all human functioning and poor sleep is a known problem in cancer, it is unclear whether the overall prevalence of the various types of sleep disorders in cancer is known. The purpose of this systematic literature review was to evaluate if the prevalence of sleep disorders could be ascertained from the current body of literature regarding sleep in cancer. This was a critical and systematic review of peer-reviewed, English-language, original articles published from 1980 through 15 October 2013, identified using electronic search engines, a set of key words, and prespecified inclusion and exclusion criteria. Information from 254 full-text, English-language articles was abstracted onto a paper checklist by one reviewer, with a second reviewer randomly verifying 50% (k = 99%). All abstracted data were entered into an electronic database, verified for accuracy, and analyzed using descriptive statistics and frequencies in SPSS (v.20) (North Castle, NY). Studies of sleep and cancer focus on specific types of symptoms of poor sleep, and there are no published prevalence studies that focus on underlying sleep disorders. Challenging the current paradigm of the way sleep is studied in cancer could produce better clinical screening tools for use in oncology clinics leading to better triaging of patients with sleep complaints to sleep specialists, and overall improvement in sleep quality.

Sleep disorders and fatigue: special issues in the older adult with cancer

Older adults with cancer reporting fatigue and sleep disorders often have coexisting geriatric syndromes and are at high risk of further functional decline. This review summarizes special considerations in the diagnosis and treatment of sleep disorders and fatigue when older persons with cancer present with multiple comorbidities, polypharmacy, dementia, delirium, and/or falls. Physicians caring for these older adults need to be aware of the unique diagnostic and treatment concerns in this population so that these patients can receive optimal care.

Is a video-based cognitive behavioral therapy for insomnia as efficacious as a professionally administered treatment in breast cancer? Results of a randomized controlled trial

STUDY OBJECTIVE

To assess the short-term efficacy of a video-based cognitive behavioral therapy for insomnia (CBT-I) as compared to a professionally administered CBT-I and to a no-treatment group.

DESIGN

Randomized controlled trial.

SETTING

Radio-oncology department of a public hospital affiliated with Université Laval (CHU de Québec).

PARTICIPANTS

Two hundred forty-two women with breast cancer who had received radiation therapy in the past 18 mo and who had insomnia symptoms or were using hypnotic medications were randomized to: (1) professionally administered CBT-I (PCBT-I; n = 81); (2) video-based CBT-I (VCBT-I; n = 80); and (3) no treatment (CTL; n = 81).

INTERVENTIONS

PCBT-I composed of six weekly, individual sessions of approximately 50 min; VCBT-I composed of a 60-min animated video + six booklets.

MEASUREMENT AND RESULTS

Insomnia Severity Index (ISI) total score and sleep parameters derived from a daily sleep diary and actigraphy, collected at pretreatment and posttreatment. PCBT-I and VCBT-I were associated with significantly greater sleep improvements, assessed subjectively, as compared to CTL. However, relative to VCBT-I, PCBT-I was associated with significantly greater improvements of insomnia severity, early morning awakenings, depression, fatigue, and dysfunctional beliefs about sleep. The remission rates of insomnia (ISI < 8) were significantly greater in PCBT-I as compared to VCBT-I (71.3% versus 44.3%, P < 0.005).

CONCLUSIONS

A self-administered cognitive behavioral therapy for insomnia (CBT-I) using a video format appears to be a valuable treatment option, but face-to-face sessions remain the optimal format for administering CBT-I efficaciously in patients with breast cancer. Self-help interventions for insomnia may constitute an appropriate entry level as part of a stepped care model.

Sleeping well with cancer: a systematic review of cognitive behavioral therapy for insomnia in cancer patients

Individuals with cancer are disproportionately affected by sleep disturbance and insomnia relative to the general population. These problems can be a consequence of the psychological, behavioral, and physical effects of a cancer diagnosis and treatment. Insomnia often persists for years and, when combined with already high levels of cancer-related distress, may place cancer survivors at a higher risk of future physical and mental health problems and poorer quality of life. The recommended first-line treatment for insomnia is cognitive behavioral therapy for insomnia (CBT-I), a non-pharmacological treatment that incorporates cognitive and behavior-change techniques and targets dysfunctional attitudes, beliefs, and habits involving sleep. This article presents a comprehensive review of the literature examining the efficacy of CBT-I on sleep and psychological outcomes in cancer patients and survivors. The search revealed 12 studies (four uncontrolled, eight controlled) that evaluated the effects of CBT-I in cancer patients or survivors. Results suggest that CBT-I is associated with statistically and clinically significant improvements in subjective sleep outcomes in patients with cancer. CBT-I may also improve mood, fatigue, and overall quality of life, and can be successfully delivered through a variety of treatment modalities, making it possible to reach a broader range of patients who may not have access to more traditional programs. Future research in this area should focus on the translation of evidence into clinical practice in order to increase awareness and access to effective insomnia treatment in cancer care.

Sleep-wake disturbances in cancer patients: narrative review of literature focusing on improving quality of life outcomes

PURPOSE

Evidence suggests a high prevalence of sleep-wake disturbances in patients with cancer, occurring at diagnosis, during treatment, and continuing to survivorship. Yet associations between sleep-wake disturbances and the impact on quality of life outcomes is less clear. The purpose of this narrative review of the literature is to evaluate sleep-wake disturbances in patients with cancer, to describe the influence of poor sleep on quality of life as an outcome, and to evaluate the evidence to recommend future interventions.

FRAMEWORK AND METHODS

This review was guided by the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) approach. Four databases (CINAHL, MEDLINE, PsycINFO, and Embase) were searched using terms "cancer OR neoplasm", "sleep, sleep disturbance, sleep disorders or insomnia", and "quality of life"; the search included all years, English language, and peer-reviewed articles on research studies. Studies included measurements of sleep and quality of life in cancer patients at a minimum of two time points and demonstrated relationships between sleep and quality of life. Data were collected on date, patient demographics, cancer type and treatment, timeframe, design, measurement, variables, and results.

RESULTS

This narrative review demonstrates that sleep-wake disturbance is a major problem/symptom in patients with cancer. Of the 18 studies included, measurement of sleep-related variables included objective and subjective measures; however, direct measurement of the associations between sleep and quality of life was not common. Cognitive behavioral therapy for insomnia and mind-body interventions demonstrated feasibility when implemented into cancer care settings. In addition, the majority of interventions exhibited moderate effectiveness in improving sleep-wake disturbance and quality of life outcomes.

CONCLUSION

The studies predominantly reported that poor sleep negatively impacts quality of life. The intervention studies included nonpharmacologic interventions such as cognitive behavioral treatment and mind-body and exercise interventions with moderate-to-high levels of evidence for improvement in sleep measures and quality of life.

Psychosocial interventions for men with prostate cancer

BACKGROUND

As the incidence and prevalence of prostate cancer continue to rise, the number of men needing help and support to assist them in coping with disease and treatment-related symptoms and their psychosocial effects is likely to increase.

OBJECTIVES

To evaluate the effectiveness of psychosocial interventions for men with prostate cancer in improving quality of life (QoL), self-efficacy and knowledge and in reducing distress, uncertainty and depression.

SEARCH METHODS

We searched for trials using a range of electronic databases including the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE and PsycINFO to October 2013, together with handsearching of journals and reference lists.

SELECTION CRITERIA

Randomised controlled trials of psychosocial interventions for men at any stage of prostate cancer. We included psychosocial interventions that explicitly used one or a combination of the following approaches: cognitive behavioural, psychoeducational, supportive and counselling. Interventions had to be delivered or facilitated by trained or lay personnel.

DATA COLLECTION AND ANALYSIS

Pairs of review authors independently extracted data and assessed risk of bias. We analysed data using standardised mean differences (SMDs), random-effects models and 95% confidence intervals (CIs).

MAIN RESULTS

Nineteen studies comparing psychosocial interventions versus usual care in a total of 3204 men with prostate cancer were included in this review. All but three of these studies were conducted in the United States.Men in the psychosocial intervention group had a small, statistically significant improvement in the physical component of general health-related quality of life (GHQoL) at end of intervention (1414 participants, SMD 0.12, 95% CI 0.01 to 0.22) based on low-quality evidence. A small improvement in favour of psychosocial interventions (SMD 0.24, 95% CI 0.02 to 0.47) was also seen in the physical component of GHQoL at end of intervention for group-based interventions. No clear evidence of benefit was found for GHQoL scores at end of intervention with individual-based interventions compared with controls. Also, no clear evidence suggested that psychosocial interventions were beneficial in improving the physical component of GHQoL at four to six and at eight to 12 months post-intervention. In addition, no clear evidence showed benefit associated with psychosocial interventions for the mental component of GHQoL at end of intervention (1416 participants, SMD -0.04, 95% CI -0.15 to 0.06) based on moderate-quality evidence. Results for the mental component of GHQoL at four to six and at eight to 12 months post-intervention were compatible with benefit and harm. At end of intervention, cancer-related QoL showed a small improvement following psychosocial interventions (SMD 0.21, 95% CI 0.04 to 0.39), but at eight and 12 months, the effect was compatible with benefit and harm. For prostate cancer-specific and symptom-related QoL, the differences between groups were not significant.No clear evidence indicated that psychosocial interventions were beneficial in improving self-efficacy at end of intervention (337 participants, SMD 0.16, 95% CI -0.05 to 0.38) based on very low-quality evidence in three studies that assessed individual-based interventions. The results for self-efficacy at six to eight and at 12 months post-intervention were compatible with benefit and harm. Men in the psychosocial intervention group had a moderate increase in prostate cancer knowledge at end of intervention (506 participants, SMD 0.51, 95% CI 0.32 to 0.71) based on very low-quality evidence in two studies; this increase was also observed in the subgroups of group-based and individual-based interventions. A small increase in knowledge with psychosocial interventions was noted at three months post-intervention (SMD 0.31, 95% CI 0.04 to 0.58).The results for uncertainty (916 participants, SMD -0.05, 95% CI -0.35 to 0.26) and distress (916 participants, SMD 0.02, 95% CI -0.11 to 0.15) at end of intervention were compatible with both benefit and harm based on very low-quality evidence. No clear evidence suggests that psychosocial interventions were beneficial in reducing uncertainty and distress between groups at six to eight and at 12 months post-intervention. Finally, no clear evidence of benefit is associated with psychosocial interventions for depression at end of intervention (434 participants, SMD -0.18, 95% CI -0.51 to 0.15) based on very low-quality evidence. Individual-based interventions significantly reduced depression when compared with usual care groups. The results for depression at six and at 12 months post-intervention were compatible with benefit and harm.The overall risk of bias in the included studies was unclear or high, primarily as the result of performance bias.No data regarding stage of disease or treatment with androgen deprivation therapy (ADT) were extractable for subgroup analysis. Only one study addressed adverse effects. High attrition could indicate that some participants may not have been comfortable with the interventions.

AUTHORS' CONCLUSIONS

Overall, this review shows that psychosocial interventions may have small, short-term beneficial effects on certain domains of well-being, as measured by the physical component of GHQoL and cancer-related QoL when compared with usual care. Prostate cancer knowledge was also increased. However, this review failed to demonstrate a statistically significant effect on other domains such as symptom-related QoL, self-efficacy, uncertainty, distress or depression. Moreover, when beneficial effects were observed, it remained uncertain whether the magnitude of effect was large enough to be considered clinically important. The quality of evidence for most outcomes was rated as very low according to GRADE, reflecting study limitations, loss to follow-up, study heterogeneity and small sample sizes. We were unable to perform meaningful subgroup analyses based on disease stage or treatment modality. Although some findings of this review are encouraging, they do not provide sufficiently strong evidence to permit meaningful conclusions about the effects of these interventions in men with prostate cancer. Additional well-done and transparently reported research studies are necessary to establish the role of psychosocial interventions in men with prostate cancer.

Self-relaxation training can improve sleep quality and cognitive functions in the older: a one-year randomised controlled trial

AIMS AND OBJECTIVE

To evaluate the effects of self-relaxation training on sleep quality and cognitive functions in the older.

BACKGROUND

Ageing causes declines in sleep quality and cognitive functions in older adults, and decreased sleep quality also accelerates declines in cognitive functions. Therefore, it is necessary to find cost-effective interventions to enhance sleep quality in the older, thereby improving their cognitive functions or delaying cognitive decline.

DESIGN

Randomised controlled study.

METHODS

The study was conducted between July 2010 and June 2011 at Wangyuehu Community in Changsha, China. Eighty older adults with reduced sleep quality were selected and randomly assigned to experimental (n = 40) or control (n = 40) group. Subjects in the experimental group received self-relaxation training including progressive muscle relaxation and meditation based on sleep hygiene education, while the control group received sleep hygiene education only. Sleep quality and cognitive functions of the two groups were measured prior to training and at the end of the 3rd, 6th and 12th months using four reliable and valid questionnaires.

RESULTS

Repeated measures anova revealed that the self-relaxation training had significant main effect as well as interaction effect with time on sleep quality and cognitive functions. Except for scores of Epworth Sleepiness Scale, Mini-Mental State Examination and number memory, time had significant main effect on scores of Pittsburgh Sleep Quality Index, picture memory, associative memory and understanding memory.

CONCLUSION

Self-relaxation training can improve sleep quality and cognitive functions in the older.

RELEVANCE TO CLINICAL PRACTICE

Self-relaxation training is a non-invasive, simple and inexpensive therapeutic method of improving sleep quality and cognitive functions in community-dwelling older people.

Cancer-Related Insomnia

Insomnia increases cancer symptom burden and impairs quality of life. The lack of standard definitions and treatment guidelines makes management difficult. Insomnia is common in most cancers but appears particularly so in lung, breast, and head and neck tumors. Older women seem most susceptible. Insomnia not only affects patients with cancer but also caregivers and families. Systematic screening is important. Few validated assessment scales are available. Nonpharmacologic therapies like cognitive behavioral therapy may help. New nonbenzodiazepine hypnotics may have some therapeutic advantages over older agents. Management of associated or contributory symptoms like fatigue, pain, and hot flashes with appropriate symptom-specific agents is important. Successful management may have a significant positive impact on global quality of life.

The effect of Benson's relaxation technique on the quality of sleep of Iranian hemodialysis patients: a randomized trial

OBJECTIVE

This study was performed to evaluate the effectiveness of Benson's relaxation technique in the quality of sleep of hemodialysis patients.

DESIGN

It was a randomized controlled trial with a pre-post-test design. A total of 86 hemodialysis patients referring to hemodialysis units were assigned to either the intervention (receiving Benson's relaxation technique) or the control group (routine care) through block randomization.

SETTING

The study was performed in two hemodialysis units affiliated to Shiraz University of Medical Sciences, Shiraz, Iran.

INTERVENTION

The patients in the intervention group listened to the audiotape of Benson's relaxation technique twice a day each time for twenty minutes for eight weeks.

MAIN OUTCOME MEASURES

The global score of Pittsburgh Sleep Quality Index (PSQI) as well as its components was computed in both the intervention and the control group before and at the 8th week of the intervention.

RESULTS

The results of ANCOVA indicated significant differences between the two groups regarding the scores of Pittsburgh Sleep Quality Index subscales, such as sleep disturbance, daytime dysfunction, the use of sleep medication, and subjective sleep quality and as well as its global scores at the 8th week of the intervention (p<0.05).

CONCLUSIONS

This study highlighted the importance of Benson's relaxation technique in improvement of the sleep quality of the patients on hemodialysis. Thus, educational sessions are recommended to be planned on this cost effective and easy to use relaxation technique in order to improve hemodialysis patients' sleep quality. Further studies are needed to assess the effectiveness of this technique in other groups of patients.

Sleep related beliefs and their association with alcohol relapse following residential alcohol detoxification treatment

BACKGROUND

Alcohol dependence is known to impact upon sleep, and poor sleep has been shown to affect relapse rates following treatment for alcohol dependence.

AIMS

The aim of this study was to investigate the association between sleep problems and relapse in dependent drinkers in an inpatient setting. This was done by studying sleep related cognitions in individuals undergoing medically assisted alcohol withdrawal.

METHOD

Sleep and sleep-related cognitions data were collected for 71 individuals undergoing detoxification treatment. Sleep was measured using sleep diaries and actigraph motion monitors. Participants completed sleep-related cognition questionnaires and were subject to telephone follow-up interviews. The results were then used to predict relapse rates 4 weeks after discharge.

RESULTS

Longer sleep onset latency recorded on the unit predicted relapse at 4 weeks. Higher dysfunctional beliefs about sleep were found to be associated with lower relapse rates.

CONCLUSIONS

This study suggests that some dysfunctional beliefs about sleep may support recovery following discharge from treatment. The study further supports the need for tailored cognitive-behavioural treatments for sleep difficulties in this population to reduce relapse rates.

Prevalence, putative mechanisms, and current management of sleep problems during chemotherapy for cancer

Sleep problems are highly prevalent in cancer patients undergoing chemotherapy. This article reviews existing evidence on etiology, associated symptoms, and management of sleep problems associated with chemotherapy treatment during cancer. It also discusses limitations and methodological issues of current research. The existing literature suggests that subjectively and objectively measured sleep problems are the highest during the chemotherapy phase of cancer treatments. A possibly involved mechanism reviewed here includes the rise in the circulating proinflammatory cytokines and the associated disruption in circadian rhythm in the development and maintenance of sleep dysregulation in cancer patients during chemotherapy. Various approaches to the management of sleep problems during chemotherapy are discussed with behavioral intervention showing promise. Exercise, including yoga, also appear to be effective and safe at least for subclinical levels of sleep problems in cancer patients. Numerous challenges are associated with conducting research on sleep in cancer patients during chemotherapy treatments and they are discussed in this review. Dedicated intervention trials, methodologically sound and sufficiently powered, are needed to test current and novel treatments of sleep problems in cancer patients receiving chemotherapy. Optimal management of sleep problems in patients with cancer receiving treatment may improve not only the well-being of patients, but also their prognosis given the emerging experimental and clinical evidence suggesting that sleep disruption might adversely impact treatment and recovery from cancer.

Evaluation of the effect of progressive relaxation exercises on fatigue and sleep quality in patients with multiple sclerosis

BACKGROUND AND OBJECTIVES

Fatigue and sleep problems are very commonly observed in patients with multiple sclerosis (MS). The Progressive Muscle Relaxation Technique (PMRT), used as one of the alternative methods in recent years, is reported to have benefits such as facilitating sleep and reducing sensitivity against fatigue. This research was conducted to investigate the effect of PMRT on fatigue and sleep quality in patients with MS.

SETTING AND DESIGN

This research was performed as a single-group pretest/post-test pretrial model. The research was conducted between March 2008 and December 2009 in the neurology polyclinic.

MATERIALS AND METHODS

The study was conducted with 32 patients who met the research criteria and agreed to participate in the study. A Personal Information Form was used as a data collection tool, Fatigue Severity Scale was used for measuring fatigue, and the Pittsburgh Sleep Quality Index was used for evaluating the sleep quality. PMRT was applied to the sample group once a day for 6 weeks.

STATISTICAL ANALYSIS

Percentage, paired t-test, and Pearson's correlation analysis were used in the assessment of data.

RESULTS

It was determined that PMRT decreased patients' fatigue level and improved their sleep quality, and this difference was observed to be statistically significant. Moreover, patients' fatigue level increased as their sleep quality decreased.

CONCLUSIONS

This study supports the effect of PMRT on fatigue and sleep quality in patients with MS, and it is recommended that further studies be conducted on this subject in the future.

Promoting sleep for hospitalized patients with advanced cancer with relaxation therapy: experience of a randomized study

AIMS AND OBJECTIVES

Sleep disorders are frequent in patients with advanced cancer receiving palliative care. The objective of this study was to demonstrate whether relaxation therapy can improve their satisfaction with sleep.

BACKGROUND

Few studies have investigated the effectiveness of relaxation in patients hospitalized with an advanced chronic disease.

DESIGN

Prospective randomized study with an immediate intervention group (IIG; relaxation days 3-6) and a delayed intervention group (DIG; relaxation days 6-9).

METHODS

The main measure was the overall satisfaction of sleep measured on a Numerical Rating Scale of Satisfaction of Sleep (NRSSS) between 0 and 10.

RESULTS

Totally 18 (IIG: 9; DIG: 9) patients were included in this study (mean age 66 ± 10.7). The NRSSS improved in both the groups (almost statistically significant) between the day of inclusion and day 2. Because of the dropout of the patients during the last days of the study, we analyzed the improvement in sleep satisfaction only between day 2 and 5. The NRSSS D5 for the immediate and delayed groups were 4.0 ± 23 and 3.8 ± 2.3, respectively. There was no significant improvement in both the groups.

CONCLUSION

The results demonstrated the difficulty to include patients with advanced cancer in a randomized study with a DIG. We were not able to demonstrate the effectiveness of relaxation therapy on sleep satisfaction.

RELEVANCE TO CLINICAL PRACTICE

Techniques that can be easily used to improve sleep in patients with an advanced cancer should be developed and used already early in the disease.

Initial evaluation of an Internet intervention to improve the sleep of cancer survivors with insomnia

OBJECTIVE

Insomnia is a common complaint among cancer survivors. Fortunately, cognitive-behavioral therapy for insomnia (CBT-I) has been shown to be an effective treatment in this population. However, it is rarely implemented given its limited availability. To address this barrier, we examined the ability of an easily accessible online CBT-I program to improve insomnia symptoms in cancer survivors.

METHODS

Twenty-eight cancer survivors with insomnia were randomly assigned to either an Internet insomnia intervention (n = 14) or to a waitlist control group (n = 14). The online program, Sleep Healthy Using The Internet, delivers the primary components of CBT-I (sleep restriction, stimulus control, cognitive restructuring, sleep hygiene, and relapse prevention). Pre- and post-assessment data were collected via online questionnaires and daily sleep diaries.

RESULTS

Participants in the Internet group showed significant improvements at post-assessment compared with those in the control group in overall insomnia severity (F(1,26) = 22.8; p<0.001), sleep efficiency (F(1,24) = 11.45; P = 0.002), sleep onset latency (F(1,24) = 5.18; P = 0.03), soundness of sleep (F(1,24) = 9.34; P = 0.005), restored feeling upon awakening (F(1,24) = 11.95; P = 0.002), and general fatigue (F(1,26) = 13.88; P = 0.001). Although other group × time interactions were not significant, overall adjusted effect sizes for all sleep variables as well as for fatigue, depression, anxiety, and quality of life ranged from small to large.

CONCLUSIONS

CBT-I delivered through an interactive, individually tailored Internet intervention may be a viable treatment option for cancer survivors experiencing insomnia.

Prevalence and risk factors for insomnia among breast cancer patients on aromatase inhibitors

PURPOSE

Insomnia is increasingly recognized as a major symptom outcome in breast cancer; however, little is known about its prevalence and risk factors among women receiving aromatase inhibitors (AIs), a standard treatment to increase disease-free survival among breast cancer patients.

METHODS

A cross-sectional survey study was conducted among postmenopausal women with stage 0-III breast cancer receiving adjuvant AI therapy at an outpatient breast oncology clinic of a large university hospital. The insomnia severity index (ISI) was used as the primary outcome. Multivariate logistic regression analyses were performed to evaluate risk factors.

RESULTS

Among 413 participants, 130 (31.5 %) had subthreshold insomnia on the ISI, and 77 (18.64 %) exceeded the threshold for clinically significant insomnia. In a multivariate logistic regression model, clinically significant insomnia was independently associated with severe joint pain (adjusted odds ratio (AOR) 4.84, 95 % confidence interval (CI) 1.71-13.69, P = 0.003), mild/moderate hot flashes (AOR 2.28, 95 % CI 1.13-4.60, P = 0.02), severe hot flashes (AOR 2.29, 95 % CI 1.23-6.81, P = 0.015), anxiety (AOR 1.99, 95 % CI 1.08-3.65, P = 0.027), and depression (AOR 3.57, 95 % CI 1.48-8.52, P = 0.004). Age (>65 vs. <55 years; AOR 2.31; 95 % CI 1.11-4.81; P = 0.026) and time since breast cancer diagnosis (<2 vs. 2-5 years; AOR 1.94; 95 % CI 1.02-3.69; P = 0.045) were also found to be significant risk factors. Clinical insomnia was more common among those who used medication for treating insomnia and pain.

CONCLUSIONS

Insomnia complaints exceed 50 % among AI users. Clinically significant insomnia is highly associated with joint pain, hot flashes, anxiety and depression, age, and time since diagnosis.
