RESUMO
Background: Obstructive sleep apnea (OSA) has been associated with mental disorders, but the strength of this association is unknown. The aim of our study was to investigate the association among OSA, depression, and anxiety in adults and to quantitatively summarize the results. Methods: A literature search in Medline, PubMed, PsycInfo, Scopus, and Web of Science was conducted. Seventy-three articles were selected for study. Results: The pooled prevalence of depressive and anxious symptoms in OSA patients was 35% (95% CI, 28-41%) and 32% (95% CI, 22-42%), respectively. Conclusions: The association between OSA, anxiety, and depression indicates the value of an early diagnosis and personalized treatment of OSA to improve mental disorders conditioning compliance to therapy. These conditions share a probably bidirectional relationship.

BACKGROUND: Obstructive sleep apnea (OSA) is a chronic illness that increases in prevalence with age. Treatment includes continuous positive airway pressure (CPAP) devices. Studies about the use of CPAP in the elderly are scarce. The main objective of this study is to determine whether CPAP contributes to improvement in health-related quality of life (HRQL) in elderly patients with OSA. METHOD: This was a prospective, pre-/postintervention assessment of a cohort of patients ≥65 years of age with OSA diagnosis by polysomnography who were being treated with CPAP and were physically independent and had good cognitive status. We determined HRQL before and after 3 months of CPAP treatment using the Short Form-36 Health Survey (SF-36, a 36-item, patient-reported survey) and Sleep Apnea Quality of Life Index (SAQLI). The effect of CPAP on daytime sleepiness was assessed with the Epworth Sleepiness Scale (ESS). RESULTS: Of the 103 participants with a mean age of 71.5 ± 4.19 years, 66% were male. After 3 months of therapy, the mean CPAP usage was 6.3 ± 1.41 hr/day. The effectiveness of CPAP in controlling the OSA was demonstrated (mean difference pre- and posttherapy: 34.30 ± 18.52 events/hr, p < .001). Postintervention, the categories of the SF-36 improved meaningfully ( p < .001). Moreover, all categories of SAQLI improved ( p < .001) with the exception of "symptoms" ( p = .073). ESS scores also improved significantly (difference = 5.2 ± 4.47, p < .001) postintervention. CONCLUSION: Therapy with CPAP in elderly patients with OSA helps improve their HRQL and reduces daytime sleepiness.

In 2015, the American College of Surgeons (ACoS) Commission on Cancer will require cancer centers to implement screening programs for psychosocial distress as a new criterion for accreditation. A joint task force from the American Psychosocial Oncology Society, the Association of Oncology Social Work, and the Oncology Nursing Society developed consensus-based recommendations to guide the implementation of this requirement. In this review, the authors provide recommendations regarding each of the 6 components necessary to meet the ACoS standard: 1) inclusion of psychosocial representation on the cancer committee, 2) timing of screening, 3) method/mode of screening, 4) tools for screening, 5) assessment and referral, and 6) documentation.

OBJECTIVE: Cancer patients are more likely to experience depression than the general population. This study aims to evaluate the possible association between cancer stigma and depression among cancer patients. METHODS: As a part of the Korean government's program to develop comprehensive supportive care, we conducted a nationwide survey in 2010 at the National Cancer Center and in nine regional cancer centers across Korea. Cancer stigma was assessed by using a set of 12 questions grouped in three domains-impossibility of recovery, stereotypes of cancer patients, and experience of social discrimination. Depression was measured by using the Hospital Anxiety and Depression Scale. RESULTS: A total of 466 cancer patients were included in the study. Over 30% of the cancer survivors had negative attitudes toward cancer and held stereotypical views of themselves: about 10% of the participants experienced social discrimination due to cancer, and 24.5% reported clinically significant depressive symptoms. Patients who had or experienced cancer stigma were 2.5 times more likely to have depression than patients with positive attitudes. CONCLUSIONS: Regardless of highly developed medical science and increased survivorship, cancer survivors had cancer stigmas, and it was significantly associated with depression. IMPACT: Our findings emphasize the need for medical societies and health professionals to pay more attention to cancer stigma that patients are likely to experience during treatment.

BACKGROUND: Obesity is associated with an increased risk for recurrence and all-cause mortality in breast cancer survivors. Excess adiposity is associated with increased estrogen, insulin, and leptin, and with decreased sex hormone binding globulin (SHBG) concentrations, which may promote breast cancer progression and recurrence. This study aimed to assess the effects of weight loss on these factors. PATIENTS AND METHODS: Breast cancer survivors who were overweight or obese (n = 220) and who were enrolled in a weight loss intervention study provided baseline and follow-up blood samples and weight data. Serum estrogens, SHBG, insulin, and leptin were measured at baseline, 6 months, and 18 months. RESULTS: Weight loss of ≥5% of initial weight decreased leptin and insulin compared with those who did not achieve that amount of weight loss (P < .0001). Weight loss also increased SHBG at 6 and 18 months (P < .01). Postmenopausal women who lost ≥5% of body weight at 6 months had lower estrone (P = .02), estradiol (P = .002), and bioavailable estradiol (P = .001) concentrations than women who did not lose at least 5% of body weight, and weight loss at 18 months was significantly related to a change in serum bioavailable estradiol concentration (P = .02). CONCLUSIONS: Favorable changes in estrogens, SHBG, insulin, and leptin were observed in association with weight loss in these women who were overweight or obese and who had been diagnosed and treated for breast cancer. Weight loss appears to have favorable effects on hormonal and biologic factors associated with increased risk for recurrence and poorer prognosis.

OBJECTIVES: This study aims to validate the ability to perform depression screening with the patient health questionnaire (PHQ)-2 and PHQ-9 depression modules in a busy, outpatient practice, and to evaluate the prevalence of depression among lung cancer outpatients at our institution. METHODS: In 2010, 64 patients in a thoracic malignancy clinic completed the Patient Health Questionnaire-2. Patients endorsing either one or both items were then given the Patient Health Questionnaire-9, a nine-item depression assessment tool. Patients with mild or worse depression were offered a referral to a mental health care provider. RESULTS: Eighteen of 64 patients (28 %) endorsed one or both items on the PHQ-2. Thirteen of 18 patients with a positive PHQ-2 screen completed the PHQ-9, with mean score of 10.2 (SD 3.91), suggesting moderate depression. PHQ-9 item 4, evaluating fatigue, was positive in 12 patients, and PHQ-9 item 9, evaluating suicidal ideation, was never reported. Only 1 of 18 patients with a positive PHQ-2 screen was being followed by a psychiatrist, and no patient accepted a new referral to a mental health provider. CONCLUSIONS: The PHQ-2 and PHQ-9 modules are an effective means of depression screening in a busy, outpatient clinic. A high prevalence of depression was reported; yet, suicidal ideation was not reported. Depression severity ranged from mild to severe. The most endorsed PHQ-9 item was fatigue, although it is uncertain if this reflects a symptom of depression, a sequela of lung cancer itself, or both. The lung cancer patients in this sample who reported depression were unlikely to receive mental health services.

Study Objectives. Continuous positive airway pressure (CPAP) therapy is efficacious for treating obstructive sleep apnea (OSA), but recent studies with placebo CPAP (CPAP administered at subtherapeutic pressure) have revealed nonspecific (or placebo) responses to CPAP treatment. This study examined baseline psychological factors associated with beneficial effects from placebo CPAP treatment. Participants. Twenty-five participants were studied with polysomnography at baseline and after treatment with placebo CPAP. Design. Participants were randomized to either CPAP treatment or placebo CPAP. Baseline mood was assessed with the Profile of Mood States (POMS). Total mood disturbance (POMS-Total) was obtained by summing the six POMS subscale scores, with Vigor weighted negatively. The dependent variable was changed in apnea-hypopnea index (ΔAHI), calculated by subtracting pre- from post-CPAP AHI. Negative values implied improvement. Hierarchical regression analysis was performed, with pre-CPAP AHI added as a covariate to control for baseline OSA severity. Results. Baseline emotional distress predicted the drop in AHI in response to placebo CPAP. Highly distressed patients showed greater placebo response, with a 34% drop (i.e., improvement) in AHI. Conclusion. These findings underscore the importance of placebo-controlled studies of CPAP treatment. Whereas such trials are routinely included in drug trials, this paper argues for their importance even in mechanical-oriented sleep interventions.
RESUMO
OBJECTIVE: People with cancer may experience distress related to diagnoses, disease-related symptoms, and treatment side effects. Assessment of cancer-related needs can facilitate timely triage and intervention and contribute to individualized comprehensive cancer care. This study assessed the internal consistency, test-retest reliability and construct validity of the Cancer Needs Distress Inventory (CaNDI), a self-report, needs-based measure of cancer-related distress. METHODS: A sample of 100 patients (27% male) with various cancer diagnoses completed the CaNDI, Hospital Anxiety and Depression Scale, Brief Symptom Inventory, Functional Assessment of Cancer Therapy-General, and the Paulhus Deception Scales. RESULTS: The CaNDI total and depressive and anxiety subscale scores all demonstrated excellent test-retest reliability and moderate to high correlations with other measures of these constructs. The instrument was minimally confounded by social desirability and provided high sensitivity and specificity in detecting depression and anxiety. CONCLUSIONS: Initial results suggest that the CaNDI has strong psychometric properties and may be a useful addition to cancer patient needs assessment, research and care.

PURPOSE: Patients with obstructive sleep apnea (OSA) commonly have cognitive complaints. There are few randomized studies that have examined neuropsychological effects of continuous positive airway pressure (CPAP) treatment in patients with OSA. In this double-blind trial, we examined if a 3-week CPAP treatment compared with placebo CPAP treatment has specific therapeutic effects on cognitive impairments in patients with OSA and if there are specific domains of cognitive impairments sensitive to 3-week CPAP treatment. SUBJECTS AND METHODS: Thirty-eight newly diagnosed patients with untreated OSA underwent neuropsychological testing before and after 3-weeks CPAP or Placebo CPAP treatment. The two treatment groups (therapeutic CPAP, and placebo-CPAP) were compared using repeated measures analysis of variance (ANOVA). RESULTS AND CONCLUSION: Impairments in neuropsychological functioning ranged from 2.6% to 47.1% before treatment. In response to 3 weeks of treatment, there was no significant time by treatment interaction for a global deficit score of neuropsychological functioning. Only the Stroop Color (number correct) test showed significant improvement specific to CPAP treatment. The study demonstrates the importance of further randomized placebo controlled studies in this area.
RESUMO
OBJECTIVE: This systematic and quantitative review evaluates the literature on associations between depressed mood and flow-mediated dilation (FMD), a measure of endothelial function, in adults. METHODS: Published English-language articles (through December 2010) were identified from literature searches, assessed for data extraction, and evaluated for quality. RESULTS: The literature includes cross-sectional (n = 9) and retrospective examinations (n = 3) of how FMD correlates with clinical or subclinical depression in healthy adults and cardiovascular patients (total N across 12 studies = 1491). FMD was assessed using a variety of methodologies. Samples were predominately older white and Asian subjects with higher socioeconomic status. In eight of the 12 articles selected for this review, at least one significant inverse association was noted between depressed mood and FMD, with primarily moderate effect sizes. The overall meta-analysis (random-effects model) revealed a combined effect size of correlation coefficient r = 0.19 (95% confidence interval = 0.08-0.29, p = .001). Significant combined effects were found for subgroups of studies that a) received better quality ratings (r = 0.29), b) examined patients with cardiovascular disease or with cardiovascular disease risk factors/comorbidity (r = 0.29), c) used maximum vasodilation to quantify FMD (r = 0.27), and d) assessed samples that had a mean age of 55 years and older (r = 0.15). CONCLUSIONS: Diverse studies support the inverse correlation between depressed mood and endothelial function, as measured by FMD. This literature would be strengthened by prospective studies, increased methodological consistency in FMD testing, and broader sampling (e.g., African Americans, younger age, lower socioeconomic status).

After successful treatment of early breast cancer, many women still report pain symptoms, and attribute them to the previous illness or its treatment. However, knowledge about the long-term course of pain in breast cancer is limited. Baseline assessment included 3,088 women who received a breast cancer diagnosis on average 2 years prior to enrollment, and who completed typical medical treatments. After 4 years, a subsample of 2,160 recurrence-free women (70%) was re-assessed. The major outcome variable was the composite index for general pain symptoms. Over the 4-year course, a slight but significant increase in pain was reported. If only medical variables were examined, a triple interaction between surgery type, breast cancer stage, and time indicated that pain scores increased in most subgroups, while they decreased in stage II women after mastectomy and stage III women after lumpectomy. Using a regression analytical approach, psychological and other variables added significantly to the prediction of pain persistence. Regression analysis revealed that pain symptoms increased in those women taking tamoxifen at baseline, in those reporting depression at baseline or stressful life events during the first 12 months after enrollment. Exercise at baseline had a beneficial effect on pain recovery. The persistence or increase of pain symptoms in women surviving breast cancer is associated with some medical factors (surgery type, tamoxifen use), but also with psychological factors. Pain should be a standard outcome variable in the evaluation of cancer treatment programs.

Introducción. El síndrome de apnea/hipopnea del sueño (SAHS) es una enfermedad crónica caracterizada por episodios repetidos de obstrucción de las vías aéreas durante el sueño. Los trastornos emocionales se han asociado frecuentemente al SAHS, aunque no hay consenso entre los resultados de las diferentes investigaciones. Objetivos. Evaluar la depresión y la ansiedad en pacientes con SAHS y determinar cuáles son las variables polisomnográficas que mejor predicen el estado de ánimo en esta muestra. Pacientes y métodos. La muestra estuvo compuesta de 100 personas: 50 pacientes con SAHS, diagnosticados mediante polisomnografía convencional, y 50 sujetos sin síntomas de SAHS. Ambos grupos respondieron al inventario de ansiedad estado-rasgo y al inventario de depresión estado-rasgo. Resultados. Los resultados muestran que los pacientes con SAHS presentan niveles más elevados de depresión y ansiedad, estado y rasgo, respecto al grupo de personas sin síntomas. Las variables que mejor predijeron el estado de ánimo fueron el índice de masa corporal y el tiempo total de sueño. Conclusiones. En este estudio se muestra la repercusión que el SAHS tiene sobre el estado de ánimo de los pacientes y se confirma la compleja relación existente entre obesidad, calidad de sueño y trastornos emocionales en pacientes con SAHS (AU)
Introduction. Obstructive sleep apnea syndrome (OSAS) is a chronic illness characterized by episodes of upper airway obstruction during sleep. Mood disturbance has been frequently related to OSAS, but there is no a consensus among results of different studies.Aims. To assess depression and anxiety of patients with SAHS, and to determine which of polysomnographic variables that best predicts the mood of the patients. Patients and methods. The sample consisted of 100 subjects: 50 patients with OSAS diagnosed with traditional polysomnography,and 50 without OSAS symptoms. Both groups answered the State-Trait Anxiety Inventory and the State and Trait Depression Questionnaire. Results. The results demonstrate that the patients with OSAS show higher scores in depression and anxiety than the control group. The variables that better predict the OSAS patients mood symptoms were body mass index and total sleep time. Conclusions. This study shows the effect of the OSAS in the mood of the patients and confirms the complex relation between obesity, quality of sleep and mood disorder in OSAS patients (AU)

BACKGROUND: Obesity is characterized by chronic mild inflammation and may influence the risk and progression of cancer. PURPOSE: The current study is an exploratory analysis of the effect of a weight loss intervention that emphasized increased physical activity on inflammatory cytokines (tumor necrosis factor-α [TNF-α], interleukin-6 [IL-6], interleukin-8 [IL-8], and vascular endothelial growth factor [VEGF]) at the end of the 16-week intervention period in overweight breast cancer survivors. METHODS: Study participants averaged 56 years of age (N=68). Intervention participants (n=44 vs. 24 controls) participated in a cognitive behavioral therapy-based weight management program as part of an exploratory randomized trial. The intervention incorporated strategies to promote increased physical activity and diet modification. Baseline and 16-week data included height, weight, body composition, physical activity level, and biomarkers IL-6, IL-8, TNF-α, and VEGF. RESULTS: Weight loss was significantly greater in the intervention group than controls (-5.7 [3.5] vs. 0.2 [4.1] kg, P<0.001). Paired t tests noted favorable changes in physical activity level (P<0.001 intervention, P=0.70 control), marginally lower IL-6 levels (P=0.06 intervention, P=0.25 control) at 16 weeks for participants in the intervention group, and lower TNF-α levels for participants in the intervention (P<0.05) and control groups (P<0.001). Increased physical activity was associated with favorable changes in IL-6 for participants in the intervention group (R(2) =0.18; P<0.03). CONCLUSION: Favorable changes in cytokine levels were observed in association with weight loss in this exploratory study with overweight breast cancer survivors.

BACKGROUND: Health-related quality of life has been hypothesized to predict time to additional breast cancer events and all-cause mortality in breast cancer survivors. METHODS: Women with early-stage breast cancer (n=2967) completed the SF-36 (mental and physical health-related quality of life) and standardized psychosocial questionnaires to assess social support, optimism, hostility, and depression prior to randomization into a dietary trial. Cox regression was performed to assess whether these measures of quality of life and psychosocial functioning predicted time to additional breast cancer events and all-cause mortality; hazard ratios were the measure of association. RESULTS: There were 492 additional breast cancer events and 301 deaths occurred over a median 7.3 years (range: 0.01-10.8 years) of follow-up. In multivariate models, poorer physical health was associated with both decreased time to additional breast cancer events and all-cause mortality (p trend=0.005 and 0.004, respectively), while greater hostility predicted additional breast cancer events only (p trend=0.03). None of the other psychosocial variables predicted either outcome. The hazard ratios comparing persons with poor (bottom two quintiles) to better (top three quintiles) physical health were 1.42 (95% CI: 1.16, 1.75) for decreased time to additional breast cancer events and 1.37 (95% CI: 1.08, 1.74) for all-cause mortality. Potentially modifiable factors associated with poor physical health included higher body mass index, lower physical activity, lower alcohol consumption, and more insomnia (p<0.05 for all). CONCLUSION: Interventions to improve physical health should be tested as a means to increase time to additional breast cancer events and mortality among breast cancer survivors.

PURPOSE: This study examined how well the Psychomotor Vigilance Task (PVT) performance was related to subjective measures of fatigue. In order to study subjects presenting with a wide range of fatigue symptoms, we studied healthy individuals as well as patients with varying severity of obstructive sleep apnea. We also examined if the PVT/fatigue relationship could be influenced by depressive symptoms. SUBJECTS AND METHODS: Forty-eight participants had their sleep monitored with polysomnography. Fatigue was assessed by Multidimensional Fatigue Symptom Inventory-short form (MFSI-sf). Depressed mood was assessed by the Center for Epidemiologic Studies-Depression (CES-D) Scale. After sleep monitoring and psychological assessments, the 10-minute PVT was administered. The main outcome variable was the PVT lapse count. Simple correlations and hierarchical linear regression were used to examine the association between age, body mass index (BMI), sleep variables, apnea hypopnea index (AHI), oxygen desaturation index (ODI), CES-D, fatigue, and PVT. RESULTS AND CONCLUSION: The PVT lapse count was significantly associated with MFSI-sf physical fatigue (r = 0.324, p = 0.025). In hierarchical regression (full model R2 = 0.256, p = 0.048), higher BMI (p = 0.038), and higher MFSI-sf physical fatigue (p= 0.040) were independent predictors of the PVT lapse count. Age, AHI, ODI, and CES-D were unrelated to the PVT lapse count. In conclusion, the findings suggest that even after controlling for age, BMI, depression, and apnea severity, physical fatigue is associated with the PVT lapse.

BACKGROUND: Although objective and subjective indicators of socioeconomic status (SES) are linked to cardiovascular disease (CVD), little is known about their relationship to endothelial dysfunction, which often precedes CVD. PURPOSE: This study examined how objective and subjective SES relate to brachial artery flow-mediated dilation (FMD). METHODS: FMD was assessed in 72 healthy adults (mean age 36 years). The MacArthur Scale of Subjective Social Status assessed perceived social standing in the USA (SSS-USA) and local community (SSS-Community). Objective SES measures included income and the Hollingshead Two-Factor Index of Social Position (education, occupation). RESULTS: Adjusted regressions revealed that SSS-Community positively correlated with FMD (p < 0.05) and explained 8% of the variance. No other SES measures were significant for FMD. The association between FMD and SSS-Community remained significant (p < 0.01) after adjustment for objective SES and other covariates. CONCLUSIONS: Lower subjective social status in one's community may be linked to CVD via impaired vasodilation.

BACKGROUND: Breast cancer survivors not only experience distressing physical symptoms associated with treatments, but also are faced with psychosocial challenges. Despite growing scientific evidence that physical activity (PA) may mitigate psychosocial distress experienced by women treated for breast cancer, the literature is equivocal. PURPOSE: This study investigated the relationships between cardiorespiratory fitness (CRF), PA, and psychosocial factors in breast cancer survivors. METHOD: Data involving overweight or obese breast cancer survivors (N = 260) were examined. CRF was determined by a submaximal graded exercise test. PA, depressive symptoms, total fatigue, and global self-esteem were assessed with self-report measures. Pearson's correlations were conducted to determine associations among CRF, PA, depressive symptoms, total fatigue, and global self-esteem. Multiple regression models, with age and body mass index as covariates, were performed using continuous levels for CRF and PA. RESULTS: Bivariate correlations suggested that CRF and PA were unrelated to the psychosocial variables. One of the regression models identified a marginally significant (P = 0.06) inverse association between depressive symptoms and PA. CONCLUSION: CRF and PA were not associated with psychosocial factors in this sample of breast cancer survivors. However, minimal PA was reported by the majority of participants, so low PA variability likely influenced these findings.

OBJECTIVE: To examine the impact of mood states on endothelial function, as measured noninvasively by brachial artery flow-mediated dilation (FMD). Substantial literature indicates that negative mood is linked to cardiovascular disease (CVD). However, the mechanisms underlying this relationship are not well defined. CVD is often preceded by dysfunction of the endothelium. METHODS: Healthy adults (n = 70; mean age, 36 years) completed the Profile of Mood States (POMS), which contains six subscales (depression/dejection; tension/anxiety; anger/hostility; confusion/bewilderment; fatigue/inertia; vigor/activity) that are used to compute a total mood disturbance score for overall psychological distress. FMD was calculated (maximum percentage change in brachial artery diameter) from ultrasound assessment of arterial diameter at baseline and for 10 minutes after occlusion. RESULTS: Regressions showed that increases in POMS total mood disturbance scores were associated with decreases in endothelial function. Mood disturbance explained 10% of the variance in FMD (p < .01), after controlling for age, sex, mean arterial pressure, body mass index, and socially desirable response bias. An exploratory set of separate regressions conducted to decompose the link between FMD and total mood disturbance revealed that the following POMS subscales were inversely correlated with FMD: depression/dejection, tension/anxiety, anger/hostility, fatigue/inertia (p's < .05), and confusion/bewilderment (p < .01). CONCLUSIONS: Mood disturbance could contribute to CVD via impaired vasodilation. These preliminary results show that even mild levels of adverse psychological states, particularly depressed, anxious, angry, confused, and fatigued states, might be linked to increased cardiovascular risk.

This analysis was conducted to determine whether comorbid medical conditions predict additional breast cancer events and all-cause mortality in women with a history of early stage breast cancer. Women (n = 2,542) participating in a randomized diet trial completed a self-administered questionnaire regarding whether they were currently being treated for a wide variety of diseases (cardiovascular, diabetes, gallbladder, gastrointestinal, arthritis, and osteoporosis) and conditions (high blood pressure, elevated cholesterol level). Height and weight were measured at baseline. Participants were followed for a median of 7.3 years (range 0.8-15.0). Cox regression analysis was performed to assess whether comorbidities predicted disease-free and overall survival; hazard ratio (HR) was the measure of association. Overall, there were 406 additional breast cancer events and 242 deaths. Participants with diabetes had over twofold the risk of additional breast cancer events (HR 2.1, 95% CI: 1.3, 3.4) and mortality (HR 2.5, 95% CI: 1.4, 4.4). The presence of multiple comorbidities did not statistically significantly predict additional breast cancer events. However, compared to no comorbidities, participants with 3 or more comorbidities had a HR of 2.1, 95% CI: 1.3, 3.3 for mortality. In conclusion, type 2 diabetes is associated with poor breast cancer prognosis. Given that 85% of deaths were caused by breast cancer, these findings suggest that multiple comorbidities may reduce the likelihood of surviving additional breast cancer events.
