RESUMEN

OBJECTIVE: This randomized comparative effectiveness trial evaluated a novel insomnia treatment using acceptance and commitment therapy (ACT) among women veterans. Participants received either the acceptance and the behavioral changes to treat insomnia (ABC-I) or cognitive behavioral therapy for insomnia (CBT-I). The primary objectives were to determine whether ABC-I was noninferior to CBT-I in improving sleep and to test whether ABC-I resulted in higher treatment completion and adherence versus CBT-I. METHOD: One hundred forty-nine women veterans with insomnia disorder (Mage = 48.0 years) received ABC-I or CBT-I. The main sleep outcomes were Insomnia Severity Index (ISI), Pittsburgh Sleep Quality Index (PSQI), and sleep efficiency (SE) by actigraphy (objective) and sleep diary (subjective). Measures were collected at baseline, immediate posttreatment, and 3-month posttreatment follow-up. Treatment completion and adherence were assessed during the interventions. RESULTS: Both interventions improved all sleep outcomes from baseline to immediate posttreatment and 3-month posttreatment follow-up. At immediate posttreatment, ABC-I was statically noninferior for sleep diary SE and objective SE, but noninferiority was not statistically confirmed for ISI or PSQI total scores. At 3-month posttreatment follow-up, ABC-I was noninferior for all four of the key outcome variables. There was not a statistically significant difference between the number of participants who discontinued CBT-I (11%) versus ABC-I (18%; p = .248) before completing treatment. ABC-I was superior to CBT-I for some adherence metrics. CONCLUSIONS: Overall, ABC-I was similar in effectiveness compared to CBT-I for the treatment of insomnia and may improve adherence to some behavioral elements of treatment.

RESUMEN

STUDY OBJECTIVES: Cognitive behavioral therapy for insomnia (CBTI) for comorbid insomnia and obstructive sleep apnea (OSA) has had mixed results. We integrated CBTI with a positive airway pressure (PAP) adherence program and tested effects on sleep and PAP use. METHODS: 125 veterans (mean age 63.2, 96% men, 39% non-Hispanic white, 26% black/African American, 18% Hispanic/Latino) with comorbid insomnia and newly-diagnosed OSA (apnea-hypopnea index ≥ 15) were randomized to 5-weekly sessions integrating CBTI with a PAP adherence program provided by a "sleep coach" (with behavioral sleep medicine supervision), or 5-weekly sleep education control sessions. Participants and assessment staff were blinded to group assignment. Outcomes (baseline, 3 and 6 months) included Pittsburgh Sleep Quality Index (PSQI), 7-day sleep diary (sleep onset latency [SOL-D], wake after sleep onset [WASO-D], sleep efficiency [SE-D]), 7-day actigraphy (SE-A), and objective PAP use (hours/night and nights ≥ 4 h). Insomnia Severity Index (ISI), Epworth Sleepiness Scale (ESS), and Functional Outcomes of Sleep Questionnaire-10 (FOSQ-10) were also collected. RESULTS: Compared to controls, intervention participants showed greater improvement (baseline to 3 and 6 months, respectively) in PSQI (-3.2 and -1.7), SOL-D (-16.2 and -15.5 minutes), SE-D (10.5% and 8.5%), SE-A (4.4% and 2.6%) and more 90-day PAP use (1.3 and 0.9 more hours/night, 17.4 and 11.3 more nights PAP ≥ 4 h). 90-day PAP use at 3 months was 3.2 and 1.9 h/night in intervention versus controls. Intervention participants also had greater improvements in ISI, ESS, and FOSQ-10 (all p < 0.05). CONCLUSIONS: An intervention integrating CBTI with a PAP adherence program delivered by a supervised sleep coach improved sleep and PAP use in adults with comorbid insomnia and OSA.

RESUMEN

STUDY OBJECTIVES: To estimate the prevalence of insomnia disorder among older veterans and to study relationships among age and self-rated health, with insomnia disorder, self-reported sleep duration and sleep efficiency. METHODS: A cross-sectional postal survey of community-dwelling older veterans (older than 60 years) seen at one VA Healthcare System in the prior 18 months was performed, which was constructed to align with the general diagnostic criteria for insomnia disorder (International Classification of Sleep Disorders, Second Edition [ICSD-2]). The survey also queried self-reported sleep duration, bedtime, and wake time, which were used to calculate sleep efficiency. The survey also asked about race/ethnicity and self-rated health (using the general health item from the Short Form-36). RESULTS: A completed survey was returned by 4,717 individuals (51.9% response rate; mean age 74.1 years). Of those, 2,249 (47.7%) met ICSD-2 diagnostic criteria for insomnia disorder. In logistic regression analyses, insomnia disorder was more likely among younger age categories (odds ratios [OR] 1.4-2.5) and in those with worse self-rated health (OR 2.1-14.4). Both total nocturnal sleep time and time in bed increased with older age (all P < .001), whereas sleep efficiency did not differ. Worse self-rated health was associated with shorter total nocturnal sleep time, more time in bed, and lower (worse) sleep efficiency. CONCLUSIONS: Results of the postal survey suggest that almost half of community-dwelling older veterans have insomnia disorder, which was more common in young-old and among those with worse self-rated health. Additional work is needed to address the high burden of insomnia among older adults, including those with poor health.

RESUMEN

Subjective and objective estimates of sleep are often discordant among individuals with insomnia who typically under-report sleep time and over-report wake time at night. This study examined the impact and durability of cognitive-behavioural therapy for insomnia on improving the accuracy of sleep and wake perceptions in older adults, and tested whether changes in sleep quality were related to changes in the accuracy of sleep/wake perceptions. One-hundred and fifty-nine older veterans (97% male, mean age 72.2 years) who met diagnostic criteria for insomnia disorder were randomized to: (1) cognitive-behavioural therapy for insomnia (n = 106); or (2) attention control (n = 53). Assessments were conducted at baseline, post-treatment, 6-months and 12-months follow-up. Sleep measures included objective (via wrist actigraphy) and subjective (via self-report diary) total sleep time and total wake time, along with Pittsburgh Sleep Quality Index score. Discrepancy was computed as the difference between objective and subjective estimates of wake and sleep. Minutes of discrepancy were compared between groups across time, as were the relationships between Pittsburgh Sleep Quality Index scores and subsequent changes in discrepancy. Compared with controls, participants randomized to cognitive-behavioural therapy for insomnia became more accurate (i.e. minutes discrepancy was reduced) in their perceptions of sleep/wake at post-treatment, 6-months and 12-months follow-up (p < .05). Improved Pittsburgh Sleep Quality Index scores at each study assessment preceded and predicted reduced discrepancy at the next study assessment (p < .05). Cognitive-behavioural therapy for insomnia reduces sleep/wake discrepancy among older adults with insomnia. The reductions may be driven by improvements in sleep quality. Improving sleep quality appears to be a viable path to improving sleep perception and may contribute to the underlying effectiveness of cognitive-behavioural therapy for insomnia.

RESUMEN

We examined whether baseline self-reported physical activity is associated with the efficacy of cognitive behavioral therapy for insomnia (CBT-I) in older veterans. Community-dwelling veterans aged 60 years and older with insomnia received CBT-I in a randomized controlled trial. Participants who received active treatment were divided into low and high physical activity based on self-report. Sleep outcomes were measured by sleep diary, questionnaire and wrist actigraphy; collected at baseline, post-treatment, 6-month and 12-month follow-up. Mixed-effects models compared differences between physical activity groups in change in sleep outcome from baseline to each follow-up, and equivalence tests examined if physical activity groups were clinically equal. There were no significant differences in sleep outcomes between physical activity groups. Equivalence tests suggested possible equality in physical activity groups for five of seven sleep outcomes. Efficacy of CBT-I in older veterans was not associated with self-reported physical activity at baseline. Older adults with insomnia who report low levels of physical activity can benefit from CBT-I.

RESUMEN

OBJECTIVES: To examine relationships between cognitive expectancies about sleep and hypnotics and use of medications commonly used for insomnia (hypnotics). METHODS: We analyzed baseline data from older veterans who met diagnostic criteria for insomnia and were enrolled in a trial comparing CBTI delivered by a supervised, sleep educator to an attention control condition (N = 159; 97% male, mean age 72 years). We classified individuals as hypnotic users (N = 23) vs. non-users (N = 135) based upon medication diaries. Associations between hypnotic status and Dysfunctional Beliefs and Attitudes about Sleep-16 (DBAS) total score (0-10, higher = worse) and two DBAS medication item scores (Item 1: "…better off taking a sleeping pill rather than having a poor night's sleep;" Item 2: "Medication… probably the only solution to sleeplessness"; 0-10, higher = worse) were examined in logistic regression models. RESULTS: Higher scores on the DBAS medication items (both odds ratios = 1.3; p-values < .001) were significantly associated with hypnotic use. DBAS-16 total score was not associated with hypnotic use. CONCLUSION: Cognitive expectancy (dysfunctional beliefs) about hypnotics was associated with hypnotic use in older adults with chronic insomnia disorder. CLINICAL IMPLICATIONS: Strategies that specifically target dysfunctional beliefs about hypnotics are needed and may impact hypnotic use in older adults.

RESUMEN

OBJECTIVES: To test a new cognitive behavioral therapy for insomnia (CBT-I) program designed for use by nonclinicians. DESIGN: Randomized controlled trial. SETTING: Department of Veterans Affairs healthcare system. PARTICIPANTS: Community-dwelling veterans aged 60 and older who met diagnostic criteria for insomnia of 3 months duration or longer (N = 159). INTERVENTION: Nonclinician "sleep coaches" delivered a five-session manual-based CBT-I program including stimulus control, sleep restriction, sleep hygiene, and cognitive therapy (individually or in small groups), with weekly telephone behavioral sleep medicine supervision. Controls received five sessions of general sleep education. MEASUREMENTS: Primary outcomes, including self-reported (7-day sleep diary) sleep onset latency (SOL-D), wake after sleep onset (WASO-D), total wake time (TWT-D), and sleep efficiency (SE-D); Pittsburgh Sleep Quality Index (PSQI); and objective sleep efficiency (7-day wrist actigraphy, SE-A) were measured at baseline, at the posttreatment assessment, and at 6- and 12-month follow-up. Additional measures included the Insomnia Severity Index (ISI), depressive symptoms (Patient Health Questionnaire-9 (PHQ-9)), and quality of life (Medical Outcomes Study 12-item Short-form Survey version 2 (SF-12v2)). RESULTS: Intervention subjects had greater improvement than controls between the baseline and posttreatment assessments, the baseline and 6-month assessments, and the baseline and 12-month assessments in SOL-D (-23.4, -15.8, and -17.3 minutes, respectively), TWT-D (-68.4, -37.0, and -30.9 minutes, respectively), SE-D (10.5%, 6.7%, and 5.4%, respectively), PSQI (-3.4, -2.4, and -2.1 in total score, respectively), and ISI (-4.5, -3.9, and -2.8 in total score, respectively) (all P < .05). There were no significant differences in SE-A, PHQ-9, or SF-12v2. CONCLUSION: Manual-based CBT-I delivered by nonclinician sleep coaches improves sleep in older adults with chronic insomnia.

RESUMEN

OBJECTIVES: The aims of the study were to determine whether mild, occult sleep-disordered breathing (SDB) moderates the efficacy of cognitive behavioral therapy for insomnia (CBTI) in older adults and to explore whether CBTI reduces the number of patients eligible for positive airway pressure (PAP) therapy. METHODS: Data were analyzed for 134 adults 60 years or older with insomnia and apnea-hypopnea index (AHI) of less than 15 who were randomized to a larger study of CBTI versus a sleep education control. Sleep outcomes (sleep onset latency, total wake time, wake after sleep onset, sleep efficiency, Pittsburgh Sleep Quality Index) were compared between CBTI and control at 6 months using repeated-measures analysis of variance adjusted for baseline values. AHI of 5 or greater versus less than 5 was included as an interaction term to evaluate changes in sleep outcomes. The number of participants at baseline and 6 months with mild SDB for whom insomnia was their only other indication for PAP was also compared between CBTI and control. RESULTS: AHI status (AHI ≥ 5 [75.5% of participants] versus AHI < 5) did not moderate improvements in sleep associated with CBTI (all p values ≥ .12). Nine (45.0%) of 20 participants with mild SDB for whom insomnia was their only other indication for PAP therapy at baseline no longer had another indication for PAP at 6 months, with no significant difference between CBTI and control. CONCLUSIONS: CBTI improves sleep in older veterans with insomnia and untreated mild SDB. Larger trials are needed to assess whether CBTI reduces the number of patients with mild SDB eligible for PAP.

RESUMEN

PURPOSE: While fatigue, sleep disturbance, and depression often co-occur in breast cancer patients, treatment efficacy for this symptom cluster is unknown. A systematic review was conducted to determine whether there are specific interventions (ie, medical, pharmacological, behavioral, psychological, and complementary medicine approaches) that are effective in mitigating the fatigue-sleep disturbance-depression symptom cluster in breast cancer patients, using the Rapid Evidence Assessment of the Literature (REAL(©)) process. METHODS: Peer-reviewed literature was searched across multiple databases; from database inception - October 2011, using keywords pre-identified to capture randomized controlled trials (RCT) relevant to the research question. Methodological bias was assessed using the Scottish Intercollegiate Guidelines Network (SIGN) 50 checklist. Confidence in the estimate of effect and assessment of safety were also evaluated across the categories of included interventions via the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) methodology. RESULTS: The initial search yielded 531 citations, of which 41 met the inclusion criteria. Of these, twelve RCTs reported on all three symptoms, and eight of these were able to be included in the GRADE analysis. The remaining 29 RCTs reported on two symptoms. Studies were of mixed quality and many were underpowered. Overall, results suggest that there is: 1) promising evidence for the effectiveness of various treatment types in mitigating sleep disturbance in breast cancer patients; 2) mixed evidence for fatigue; 3) little evidence for treating depression; and 4) no clear evidence that treatment of one symptom results in effective treatment for other symptoms. CONCLUSION: More high-quality studies are needed to determine the impact of varied treatments in mitigating the fatigue-sleep disturbance-depression symptom cluster in breast cancer patients. Furthermore, we encourage future studies to examine the psychometric and clinical validity of the hypothesized relationship between the symptoms in the fatigue-sleep disturbance-depression symptom cluster.

RESUMEN

BACKGROUND: Breast cancer (BC) patients often experience cancer-related fatigue (CRF) before, during, and after their chemotherapy. Circadian rhythms are 24-hour cycles of behavior and physiology that are generated by internal pacemakers and entrained by zeitgebers (e.g., light). A few studies have suggested a relationship between fatigue and circadian rhythms in some clinical populations. METHODS: One hundred and forty-eight women diagnosed with stage I-III breast cancer and scheduled to receive at least four cycles of adjuvant or neoadjuvant chemotherapy, and 61 controls (cancer-free healthy women) participated in this study. Data were collected before (Baseline) and after four cycles of chemotherapy (Cycle-4). Fatigue was assessed with the Short Form of Multidimensional Fatigue Symptom Inventory (MFSI-SF); circadian activity rhythm (CAR) was recorded with wrist actigraphy (six parameters included: amplitude, acrophase, mesor, up-mesor, down-mesor and F-statistic). A mixed model analysis was used to examine changes in fatigue and CAR parameters compared to controls, and to examine the longitudinal relationship between fatigue and CAR parameters in BC patients. RESULTS: More severe CRF (total and subscale scores) and disrupted CAR (amplitude, mesor and F-statistic) were observed in BC patients compared to controls at both Baseline and Cycle-4 (all p's<0.05); BC patients also experienced more fatigue and decreased amplitude and mesor, as well as delayed up-mesor time at Cycle-4 compared to Baseline (all p's<0.05). The increased total MFSI-SF scores were significantly associated with decreased amplitude, mesor and F-statistic (all p's<0.006). CONCLUSION: CRF exists and CAR is disrupted even before the start of chemotherapy. The significant relationship between CRF and CAR indicate possible underlying connections. Re-entraining the disturbed CAR using effective interventions such as bright light therapy might also improve CRF.

RESUMEN

This study examined the longitudinal relation between health-related quality of life (HR-QOL) and subjective and objective sleep quality in 166 women with newly diagnosed Stage-1 through Stage-3 breast cancer, who were scheduled to receive ≥ 4 cycles of adjuvant/neoadjuvant chemotherapy. HR-QOL was assessed with the Medical Outcomes Study 36-item Short Form, Physical Component Scale (PCS), and Mental Component Scale (MCS) scores; subjective sleep was assessed with the Pittsburgh Sleep Quality Index; and objective sleep was measured with actigraphy. Data were collected before starting chemotherapy and during the last week of Cycle 4 of chemotherapy. Patients reported poor HR-QOL and poor sleep quality before and during chemotherapy. Short sleep time and long naps were recorded at both time points. The MCS score was related to reports of poor sleep, but not to recorded sleep; worse PCS scores were associated with reports of poor sleep and less recorded naptime, suggesting sleep plays an important role in cancer patients' HR-QOL.

RESUMEN

OBJECTIVES: To evaluate whether objectively and subjectively measured sleep disturbances persist among older adults in assisted living facilities (ALFs) and to identify predictors of sleep disturbance in this setting. DESIGN: Prospective, observational cohort study. SETTING AND PARTICIPANTS: A total of 121 residents, age ≥ 65 years, in 18 ALFs in the Los Angeles area. MEASUREMENTS: Objective (actigraphy) and subjective (Pittsburgh Sleep Quality Index) sleep measures were collected at baseline and 3- and 6-month follow-up. Predictors of baseline sleep disturbance tested in bivariate analyses and multiple regression models included demographics, Mini-Mental State Examination score, number of comorbidities, nighttime sedating medication use, functional status (activities of daily living; instrumental activities of daily living), restless legs syndrome, and sleep apnea risk. RESULTS: Objective and subjective sleep measures were similar at baseline and 3- and 6-month follow-up (objective nighttime total sleep [hours] 6.3, 6.5, and 6.4; objective nighttime percent sleep 77.2, 77.7, and 78.3; and Pittsburgh Sleep Quality Index total score 8.0, 7.8, and 7.7, respectively). The mean baseline nighttime percent sleep decreased by 2% for each additional unit increase in baseline comorbid conditions (measured as the number of conditions), and increased by 4.5% for each additional unit increase in baseline activities of daily living (measured as the number of activities of daily living), in a multiple regression model. CONCLUSIONS: In this study, we found that objectively and subjectively measured sleep disturbances are persistent among ALF residents and are related to a greater number of comorbidities and poorer functional status at baseline. Interventions are needed to improve sleep in this setting.

RESUMEN

Fatigue and sleep disturbances are two of the most common and distressing symptoms reported by cancer patients. Fatigue and sleep are also correlated with each other. While fatigue has been reported to be associated with some inflammatory markers, data about the relationship between cancer-related sleep disturbances and inflammatory markers are limited. This study examined the relationship between fatigue and sleep, measured both subjectively and objectively, and inflammatory markers in a sample of breast cancer patients before and during chemotherapy. Fifty-three women with newly diagnosed stage I-III breast cancer scheduled to receive at least four 3-week cycles of chemotherapy participated in this longitudinal study. Fatigue was assessed with the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF), sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI) and objective sleep was measured with actigraphy. Three inflammatory markers were examined: Interleukin-6 (IL-6), Interleukin-1 receptor antagonist (IL-1RA) and C-reactive protein (CRP). Data were collected before (baseline) and during cycle 1 and cycle 4 of chemotherapy. Compared to baseline, more fatigue was reported, levels of IL-6 increased and IL-1RA decreased during chemotherapy. Reports of sleep quality remained poor. Mixed model analyses examining changes from baseline to each treatment time point revealed overall positive relationships between changes in total MFSI-SF scores and IL-6, between changes in total PSQI scores and IL-6 and IL-1RA, and between total wake time at night and CRP (all p's<0.05). These relationships suggest that cancer-related fatigue and sleep disturbances may share common underlying biochemical mechanisms.

RESUMEN

STUDY OBJECTIVE: Fatigue and sleep disturbances are two of the most common and distressing symptoms of cancer patients. A relationship between the two symptoms was reported in symptom cluster studies; however, only subjective measurements of sleep were examined and most studies were cross-sectional. In this study of women with breast cancer undergoing chemotherapy, we explored the longitudinal relationship between fatigue and sleep measured both subjectively and objectively. DESIGN: Prospective study. Data were collected at 7 time points: before (baseline) and during the 3 weeks of cycle 1 and cycle 4 chemotherapy. PARTICIPANTS: Ninety-seven women with newly diagnosed stage I-III breast cancer who were scheduled to receive at least four 3-week cycles of chemotherapy. MEASUREMENT AND RESULTS: Objective sleep parameters were measured with an Actillume actigraph (Ambulatory Monitoring Inc.). Subjective sleep quality was assessed with the Pittsburgh Sleep Quality Index (PSQI). Fatigue was assessed with the Multidimensional Fatigue Symptom Inventory-Short Form (MFSI-SF). Fatigue became worse during both cycles of chemotherapy (P-values < 0.01). Subjective sleep quality was poor at baseline and remained unchanged throughout treatment. Objective nighttime and daytime total sleep time increased compared to baseline during the treatment administration week of both cycles; daytime total wake time decreased during the treatment week of both cycles and during the last 2 week of cycle 4. Mixed model results revealed that fatigue was positively associated with total PSQI scores and with objective measures of total nap time, and negatively associated with total wake time during the day (all P-values < 0.01). CONCLUSION: Fatigue was significantly associated with subjective reports of poor sleep and objective measures of daytime sleepiness, but not with nocturnal sleep as measured with actigraphy. This relationship between fatigue and sleep warrants further studies to explore their possible common underlying etiology.

RESUMEN

BACKGROUND: Cortisol is a stress-related hormone with a robust circadian rhythm where levels typically peak in the morning hours and decline across the day. Although acute cortisol increases resulting from stressors are adaptive, chronic elevated cortisol levels are associated with poor functioning. Studies have shown age-related changes in cortisol levels. The present study investigated the relationship between salivary diurnal cortisol and functional outcomes among older adults undergoing inpatient post-acute rehabilitation. METHODS: Thirty-two older adults (mean age 78 years; 84% men) in a Veterans Administration inpatient post-acute rehabilitation unit were studied. Functional outcomes were assessed with the motor component of the Functional Independence Measure (mFIM; where mFIM change = discharge - admission score). Saliva samples were collected on 1 day at wake time, 45 minutes later, 11:30 AM, 2 PM, 4:30 PM, and bedtime. We analyzed the relationship between cortisol measures and functional outcomes, demographics, and health measures. RESULTS: The analyses consistently showed that greater functional improvement (mFIM change) from admission to discharge was associated with lower comorbidity scores and higher cortisol levels at 2 PM, 4:30 PM, and bedtime. A morning cortisol rise was also associated with greater mFIM change. CONCLUSIONS: Measurement of cortisol in saliva may be a useful biological marker for identification of patients who are "at risk" of lower benefits from inpatient rehabilitation services and who may require additional assistance or intervention during their post-acute care stay.

RESUMEN

STUDY OBJECTIVE: To evaluate the association between self-reported sleep quality among older adults during inpatient post-acute rehabilitation and one-year survival. DESIGN: Prospective, observational cohort study. SETTING: Two inpatient post-acute rehabilitation sites (one community and one Veterans Administration). PARTICIPANTS: Older patients (aged ≥ 65 years, n = 245) admitted for inpatient post-acute rehabilitation. INTERVENTIONS: None. MEASUREMENTS AND RESULTS: Within one year of post-acute rehabilitation, 57 participants (23%) were deceased. Cox proportional hazards models showed that worse Pittsburgh Sleep Quality Index (PSQI) total scores during the post-acute care stay were associated with increased mortality risk when controlling for amount of rehabilitation therapy received, comorbidities, and cognitive functioning (Hazard ratio [95% CI] = 1.11 [1.02-1.20]). Actigraphically estimated sleep was unrelated to mortality risk. CONCLUSIONS: Poorer self-reported sleep quality, but not objectively estimated sleep parameters, during post-acute rehabilitation was associated with shorter survival among older adults. This suggests self-reported poor sleep may be an important and potentially modifiable risk factor for negative outcomes in these vulnerable older adults. Studies of interventions to improve sleep quality during inpatient rehabilitation should therefore be undertaken, and the long-term health benefits of improved sleep should be explored.

RESUMEN

Breast cancer is the most commonly diagnosed cancer in women. Insomnia is a significant problem in breast cancer patients, affecting between 20% to 70% of newly diagnosed or recently treated cancer patients. Pain, fatigue, anxiety, and depression are also common conditions in breast cancer and often co-occur with insomnia in symptom clusters, exacerbating one another, and decreasing quality of life (QOL). There have been no clinical trials of drugs for sleep in cancer. Cognitive behavioral psychotherapies on the other hand, have shown some of the most positive results in alleviating the distressing symptoms that often accompany the breast cancer experience, but even these studies have not targeted the symptom cluster. Pharmacological as well as non-pharmacological treatments need to be explored. It might be that a combined pharmacological and behavioral treatment is most efficacious. In short, substantially more research is needed to fully understand and treat the symptom cluster of insomnia, fatigue, pain, depression and anxiety in breast cancer.

RESUMEN

Insomnia is a common problem among older adults. In particular, older adults experience insomnia coupled with early morning awakenings due to an interaction between age-related changes in circadian rhythm timing coupled with behavior changes that contribute to sustained poor sleep. Cognitive-behavioral therapy for insomnia (CBT-I), at times coupled with circadian interventions (e.g., timed light exposure), are likely to be most successful in optimizing sleep quality. In delivering CBT-I to older adults, modifications are sometimes necessary to accommodate for medical problems, lifestyle, social factors, and patient preferences. Addition of circadian interventions can ameliorate the negative effects of inappropriately timed sleep as well. These treatment methods can be highly effective and benefits can be long-standing. A case example is used to illustrate these points.

RESUMEN

OBJECTIVES: To describe sleep patterns in older adults living in assisted living facilities (ALFs) and to explore the relationship between sleep disturbance and quality of life, functional status, and depression over 6 months of follow-up. DESIGN: Prospective, observational cohort study. SETTING: Eighteen ALFs in the Los Angeles area. PARTICIPANTS: One hundred twenty-one ALF residents aged 65 and older (mean age 85.3, 86% female, 88% non-Hispanic white). MEASUREMENTS: Data were collected at baseline and 3 and 6 months after enrollment. Data collected were demographics, physical and cognitive functioning, depression, quality of life, comorbidities, medications, and subjective (i.e., questionnaires) and objective (i.e., 3 days and nights of wrist actigraphy) measures of sleep. RESULTS: Sixty-five percent of participants reported clinically significant sleep disturbance on the Pittsburgh Sleep Quality Index, and objective wrist actigraphy confirmed poor sleep quality. In regression analyses including sleep variables and other predictors, more self-reported sleep disturbance at baseline was associated with worse health-related quality of life (Medical Outcomes Study 12-item Short Form Survey Mental Component Summary score) and worse depressive symptoms five-item Geriatric Depression Scale at follow-up. Worse nighttime sleep (according to actigraphy) at baseline was associated with worse activities of daily living functioning and more depressive symptoms at follow-up. CONCLUSIONS: Sleep disturbance is common in older ALF residents, and poor sleep is associated with declining functional status and quality of life and greater depression over 6 months of follow-up. Studies are needed to determine whether improving sleep in ALF residents will result in improvements in these outcomes. Well-established treatments should be adapted for use in ALFs and systematically evaluated in future research.

RESUMEN

PURPOSE: Estimates of insomnia in breast cancer patients are high, with reports of poor sleep lasting years after completion of cancer treatment. This randomized controlled crossover pilot study looked at the effects of individual cognitive behavioral therapy for insomnia (IND-CBT-I) on sleep in breast cancer survivors. PATIENTS AND METHODS: Twenty-one participants were randomly assigned to either a treatment group (six weekly IND-CBT-I sessions followed by six weeks of follow up) or a delayed treatment control group (no treatment for six weeks followed by six weekly IND-CBT-I sessions). Of these, 14 participants completed the pilot study (six in the treatment group and eight in the delayed treatment control group). RESULTS: Self-rated insomnia was significantly improved in the treatment group compared to the waiting period in the delayed treatment control group. The pooled pre-post-IND-CBT-I analyses revealed improvements in self-rated insomnia, sleep quality, and objective measures of sleep. CONCLUSIONS: These preliminary results suggest that IND-CBT-I is appropriate for improving sleep in breast cancer survivors. Individual therapy in a clinic or private practice may be a more practical option for this population as it is more easily accessed and readily available in an outpatient setting.
