Biobehavioral predictors of mood, pain, fatigue, and insomnia in endometrial cancer survivors.

Objective: Endometrial cancer survivors experience persistent health-related quality of life concerns, including pain, fatigue, and disrupted emotional and social functioning. The purpose of this longitudinal study was to evaluate associations between biobehavioral factors, including daytime physical activity, nighttime sleep, and 24-h circadian rest-activity rhythms, with psychological and physical symptoms following endometrial cancer surgery.

Methods: This study included 69 adult female patients undergoing surgery for endometrial cancer.

Biobehavioral mechanisms underlying symptoms in cancer patients with chronic graft-versus-host disease.

Chronic graft-versus-host disease (cGVHD) is a complication of allogeneic hematopoietic cell transplant (HCT) and is associated with morbidity and high symptom burden. This study evaluated two biobehavioral mechanisms, inflammation and circadian rest-activity rhythms, that may underly commonly reported psychological and physical symptoms in cGVHD patients. Adults with cGVHD (N=57) wore a wrist actigraph for 7 days, provided a blood sample, and completed patient-reported outcome (PRO) measures.

Don't hold PAT: watch for and correct oximetry artifact.

Unlabelled: This study evaluated the accuracy of the algorithmic oxygen saturation (SpO) nadir detection of WatchPAT (Zoll/Itamar, Caesarea, Israel) compared with visual inspection in a real-world setting. SpO tracings for 209 consecutive adult WatchPAT recordings were reviewed for SpO artifact, with erroneous SpO data removed manually. Error rates for SpO minima were determined across all studies, and relationships between correct and erroneous studies examined.

Sleep and Women's Mental Health.

Women have increased risks for both sleep disturbances and disorders and for mental health issues throughout their lives, starting in adolescence. Women have a higher prevalence of insomnia disorder and restless legs syndrome (RLS) versus men, and obstructive sleep apnea (OSA) is more likely as women age. Hormonal transitions are important to consider in women's sleep.

Psychological and physical function in allogeneic hematopoietic cell transplant survivors with chronic graft-versus-host disease.

Purpose: Chronic graft-versus-host disease (cGVHD) is a common late complication of allogeneic hematopoietic cell transplantation (HCT). This study comprehensively evaluated physical and psychological function among individuals with cGVHD. Additional aims were to investigate relationships between disease severity and psychological and physical function, and to investigate patterns of psychological and physical function by disease site.

A biobehavioral intervention to enhance recovery following hematopoietic cell transplantation: Protocol for a feasibility and acceptability randomized control trial.

Background: Insomnia, fatigue, and depression are among the most persistent and distressing concerns for hematologic cancer patients recovering from hematopoietic cell transplantation (HCT). This study will evaluate a novel behavioral intervention, (ReSET), designed to alleviate insomnia, fatigue, and depression by improving rest-activity patterns. Evidence-based behavioral strategies to improve nighttime sleep and increase non-sedentary daytime activity will be combined to optimize 24-h rest-activity patterns.

Potential Maladaptive Sleep-Related Cognitions in Depression with Comorbid Hypersomnolence: An Exploratory Investigation.

: Dysfunctional sleep-related cognitions (SRCs) have been demonstrated in both insomnia and depression, but have not been evaluated in patients experiencing depression with co-occurring hypersomnolence. Given the prominence of maladaptive thinking in depression with comorbid insomnia, dysfunctional SRCs may also exist in depressed persons experiencing hypersomnolence. Identifying potentially maladaptive SRCs may assist development of cognitive-behavioral strategies to alleviate hypersomnolence and its related impairment, particularly when comorbid with depression.

Sleep disruption among cancer patients following autologous hematopoietic cell transplantation.

Despite a high prevalence of sleep disruption among hematopoietic cell transplant (HCT) recipients, relatively little research has investigated its relationships with modifiable cognitive or behavioral factors or used actigraphy to characterize sleep disruption in this population. Autologous HCT recipients who were 6-18 months post transplant completed self-report measures of cancer-related distress, fear of cancer recurrence, dysfunctional sleep cognitions, and inhibitory sleep behaviors upon enrollment. Patients then wore an actigraph for 7 days and completed a self-report measure of sleep disruption on day 7 of the study.

Sex Differences in the Relationship Between Depressive Symptoms and Actigraphic Assessments of Sleep and Rest-Activity Rhythms in a Population-Based Sample.

Objective: Depression is often associated with disruptions in sleep and circadian rhythms. We aimed to confirm these relationships via actigraphic assessment in a large, population-based sample and test whether sex moderates these relationships.

Methods: A total of 418 participants (age = 35-85 years, mean [standard deviation] = 57.

Regional Patterns of Elevated Alpha and High-Frequency Electroencephalographic Activity during Nonrapid Eye Movement Sleep in Chronic Insomnia: A Pilot Study.

Study Objectives: To examine nonrapid eye movement (NREM) sleep in insomnia using high-density electroencephalography (EEG).

Methods: All-night sleep recordings with 256 channel high-density EEG were analyzed for 8 insomnia subjects (5 females) and 8 sex and age-matched controls without sleep complaints. Spectral analyses were conducted using unpaired t-tests and topographical differences between groups were assessed using statistical non-parametric mapping.

Sleep Disturbances in Mood Disorders.

The article provides an overview of common and differentiating self-reported and objective sleep disturbances seen in mood-disordered populations. The importance of considering sleep disturbances in the context of mood disorders is emphasized, because a large body of evidence supports the notion that sleep disturbances are a risk factor for onset, exacerbation, and relapse of mood disorders. In addition, potential mechanisms for sleep disturbance in depression, other primary sleep disorders that often occur with mood disorders, effects of antidepressant and mood-stabilizing drugs on sleep, and the adjunctive effect of treating sleep in patients with mood disorders are discussed.

Effects of partial sleep deprivation on slow waves during non-rapid eye movement sleep: A high density EEG investigation.

Objective: Changes in slow waves during non-rapid eye movement (NREM) sleep in response to acute total sleep deprivation are well-established measures of sleep homeostasis. This investigation utilized high-density electroencephalography (hdEEG) to examine topographic changes in slow waves during repeated partial sleep deprivation.

Methods: Twenty-four participants underwent a 6-day sleep restriction protocol.

Biopsychosocial predictors of pain among women recovering from surgery for endometrial cancer.

Objective: This study investigated post-surgical changes in pain among endometrial cancer patients, as well as the extent to which emotional distress and inflammatory and regulatory cytokine levels were associated with pain.

Methods: Women (N=71) who underwent surgery for endometrial cancer completed questionnaires assessing pain intensity and interference, depression, and anxiety at 1week, 4weeks, and 16weeks post-surgery. Participants also provided a blood sample for the analysis of a panel of 7 cytokines at the same time points.

Circadian actigraphic rest-activity rhythms following surgery for endometrial cancer: A prospective, longitudinal study.

Objective: To investigate (1) circadian rest-activity rhythm disturbances among endometrial cancer patients as they recover from surgery in comparison to a historical reference group of women with no cancer history and (2) health- and treatment-related predictors of dysregulated rest-activity rhythms in endometrial cancer patients.

Methods: 60 endometrial cancer patients participated in a prospective, longitudinal study with actigraphic assessment at 1week, 1month, and 4months post-surgery. 60 women without cancer from an epidemiological sample completed one actigraphic assessment, acting as a reference group.

Sleep Related Cognitions in Individuals with Symptoms of Insomnia and Depression.

Study Objectives: Depression has been identified as the most common condition comorbid to insomnia, with findings pointing to the possibility that these disorders may be causally related to each other or may share common mechanisms. Some have suggested that comorbid insomnia and depression may have a different clinical course than either condition alone, and may thus require specific treatment procedures. In this report we examined the clinical characteristics of individuals referred to an academic sleep center who report comorbid symptoms of insomnia and depression and those with symptoms of insomnia outside the context of meaningful depression, and we identified differences between these groups with regard to several cognitive-related variables.

Contribution of cancer symptoms, dysfunctional sleep related thoughts, and sleep inhibitory behaviors to the insomnia process in breast cancer survivors: a daily process analysis.

Study Objectives: using a comprehensive cognitive-behavioral model of insomnia and a daily process approach, this study was conducted to examine the contribution of cancer symptoms and dysfunctional sleep related thoughts and behaviors to the process of insomnia in breast cancer survivors.

Design: within-group longitudinal research design.

Setting: an academic medical center.

A comparison of conventional pain coping skills training and pain coping skills training with a maintenance training component: a daily diary analysis of short- and long-term treatment effects.

Unlabelled: Pain coping skills training (PCST) has been shown to produce immediate improvements in pain and disability in rheumatoid arthritis (RA). However, some patients have difficulty maintaining these gains. This study compared a conventional PCST protocol with a PCST protocol that included maintenance training (PCST/MT).
