Impact of coping strategies on perceived stress, depression, and cortisol profiles among gynecologic cancer patients.

We explored associations between problem-focused, emotional processing, and emotional expression coping strategies and markers of stress including perceived stress, depressive symptoms, and diurnal cortisol profiles among women with gynecologic cancer. Problem-focused coping was associated with less perceived stress, fewer depressive symptoms, and more rhythmic diurnal salivary cortisol profiles. Emotional processing was associated with lower perceived stress and fewer depressive symptoms. Emotional expression was associated with fewer depressive symptoms and elevated diurnal mean and evening cortisol levels. Results point to key differences in coping strategies. In this sample, only problem-focused coping was linked with adaptive differences in both psychological and physiological stress measures.

Relationship between obstructive sleep apnea and difficulty of anesthesia induction in children undergoing tonsillectomy.

OBJECTIVE: To determine whether anesthesiologists need to rely on polysomnography (PSG) when predicting need for airway intervention during induction in patients with sleep-disordered breathing (SDB). METHODS: Prospective case-control observational study at a tertiary care pediatric hospital. Children between the ages of 2-17 undergoing tonsillectomy were divided into three groups: those presenting with OSA observed by history and/or physical examination alone (SDB; n = 33), those with OSA determined by preoperative PSG (OSA; n = 32), and a control group (n = 35) undergoing tonsillectomy for recurrent tonsillitis. An anesthesiologist ranked each case on the level of intervention required to maintain ventilation. RESULTS: Age, height and BMI were associated with greater induction difficulty (r's > .225, p's < .025). Compared to controls, induction difficulty was significantly greater for the SDB group (mean difference = -0.751, 95% confidence interval [CI] = -1.241, -0.261, p = .003), but not for the OSA group (p = .061). No significant difference in induction difficulty was observed between SDB and OSA groups. In a subgroup analysis of the OSA group, an apnea-hypopnea index (AHI) > 10 correlated with increased level of intervention during induction (r = .228, p = .022). Race was also associated with AHI >10 (odds ratio = 3.859, 95% CI = 1.485, 10.03, p = .006). CONCLUSION: Children with OSA undergoing tonsillectomy require more airway intervention during induction than children with recurrent tonsillitis. Age and BMI were correlated with greater induction difficulty, suggesting that PSG data should be considered in light of these clinical characteristics to ensure an optimal postoperative course for children undergoing tonsillectomy.

Predictors for hemorrhage following pediatric adenotonsillectomy.

OBJECTIVE: To determine risk factors and trends for posttonsillectomy hemorrhage (PTH) following adenotonsillectomy (T&A) at a single children's tertiary referral hospital. METHODS: Charts from all patients 2-12 years old undergoing T&A alone at a single children's hospital from January 1, 2010 through December 31, 2015 were reviewed. Data was collected on patient demographics, indication for procedure, time of year, academic affiliation of surgeon, surgical technique and method, post-operative pain medication prescribed,and readmission for PTH. Univariate chi-square analyses and logistic regression along with multivariable stepwise logistic regression were used to identify predictors of PTH. SPSS version 24 was used for statistical analyses with p < .05 indicating statistical significance. RESULTS: There were 2565 children undergoing T&A during the study period. One hundred seventy-three (6.7%) patients were readmitted, of which 53 (30.6%) were due to PTH. Univariate analyses identified children at the highest age quartile of the study, 7.72-12.97 years old (odds ratio [OR] = 5.775, 95% confidence interval [CI] = 2.248-14.837, p < .001) and children with a BMI z-score of 2 or greater (OR = 3.391, 95% CI = 1.497-7.680, p = .003) were at increased risk for PTH. Multivariable analyses also identified both the highest age quartile and BMI z-score of 2 or greater to be a risk factor for PTH. CONCLUSION: In children undergoing T&A, age greater than 7.72 years old and BMI z-score of 2 or greater are significant risk factors for PTH. Replication of these findings in a more highly powered trial is needed.

Depressive symptoms and actigraphy-measured circadian disruption predict head and neck cancer survival.

OBJECTIVE: Depressive symptoms have demonstrated prognostic significance among head and neck cancer patients. Depression is associated with circadian disruption, which is prognostic in multiple other cancer types. We hypothesized that depressive symptoms would be associated with circadian disruption in head and neck cancer, that each would be related to poorer 2-year overall survival, and that relationships would be mediated by tumor response to treatment. METHODS: Patients (N = 55) reported on cognitive/affective and somatic depressive symptoms (PHQ-9) and wore an actigraph for 6 days to continuously record rest and activity cycles prior to chemoradiation. Records review documented treatment response and 2-year survival. Spearman correlations tested depressive symptoms and circadian disruption relationships. Cox proportional hazard models tested the predictive capability of depressive symptoms and circadian disruption, separately, on survival. RESULTS: Depressive symptoms were significantly associated with circadian disruption, and both were significantly associated with shorter survival (somatic: hazard ratio [HR] = 1.325, 95% confidence interval [CI] = 1.089-1.611, P = .005; rest/activity rhythm: HR = 0.073, 95% CI = 0.009-0.563, P = .012; nighttime restfulness: HR = 0.910, 95% CI = 0.848-0.977, P = .009). Tumor response to treatment appeared to partly mediate the nighttime restfulness-survival relationship. CONCLUSIONS: This study replicates and extends prior work with new evidence linking a subjective measure of depression and an objective measure of circadian disruption-2 known prognostic indicators-to shortened overall survival among head and neck cancer patients. Continued examination should elucidate mechanisms by which depressive symptomatology and circadian disruption translate to head and neck cancer progression and mortality.

Depressive symptoms predict head and neck cancer survival: Examining plausible behavioral and biological pathways.

BACKGROUND: Head and neck cancers are associated with high rates of depression, which may increase the risk for poorer immediate and long-term outcomes. Here it was hypothesized that greater depressive symptoms would predict earlier mortality, and behavioral (treatment interruption) and biological (treatment response) mediators were examined. METHODS: Patients (n = 134) reported depressive symptomatology at treatment planning. Clinical data were reviewed at the 2-year follow-up. RESULTS: Greater depressive symptoms were associated with significantly shorter survival (hazard ratio, 0.868; 95% confidence interval [CI], 0.819-0.921; P < .001), higher rates of chemoradiation interruption (odds ratio, 0.865; 95% CI, 0.774-0.966; P = .010), and poorer treatment response (odds ratio, 0.879; 95% CI, 0.803-0.963; P = .005). The poorer treatment response partially explained the depression-survival relation. Other known prognostic indicators did not challenge these results. CONCLUSIONS: Depressive symptoms at the time of treatment planning predict overall 2-year mortality. Effects are partly influenced by the treatment response. Depression screening and intervention may be beneficial. Future studies should examine parallel biological pathways linking depression to cancer survival, including endocrine disruption and inflammation.

Distress and quality of life in an ethnically diverse sample awaiting breast cancer surgery.

Poor breast cancer-related quality of life is associated with flattened cortisol rhythms and inflammation in breast cancer survivors and women with advanced disease. We explored the associations of cancer-specific distress (Impact of Events Scale), mood (Profile of Mood States), activity/sleep (wake after sleep onset, 24-hour autocorrelation coefficient) and cortisol (diurnal slope) circadian rhythms, and inflammation (interleukin-6) with quality of life (Functional Assessment of Cancer Therapy-Breast) among patients awaiting breast cancer surgery ( N = 57). Models were adjusted for differences in age and cancer stage. Distress and mood disturbance were significantly correlated with lower quality of life. Ethnic differences in the relationship between distress and mood disturbance with global quality of life and subscales of quality of life were observed. Actigraphic measures showed that in comparison with non-Hispanic patients, African Americans had significantly poorer activity/sleep (wake after sleep onset, 24-hour autocorrelation coefficient). Circadian disruption and inflammation were not associated with quality of life. Physiological dysregulation and associated comorbidities may take time to develop over the course of disease and treatment.

Mindfulness meditation alleviates fibromyalgia symptoms in women: results of a randomized clinical trial.

BACKGROUND: Several recent reviews have evaluated evidence on the efficacy of Mindfulness-Based Stress Reduction (MBSR) among fibromyalgia sufferers, and concluded that more research should test effects on both psychological and physiological functioning. PURPOSE: We conducted a randomized prospective trial of MBSR among female fibromyalgia patients. METHODS: Effects on perceived stress, pain, sleep quality, fatigue, symptom severity, and salivary cortisol were tested in treatment (n=51) versus wait-list control participants (n=40) using data at baseline, post-program, and 2-month follow-up. RESULTS: Analyses revealed that MBSR significantly reduced perceived stress, sleep disturbance, and symptom severity, with gains maintained at follow-up. Greater home practice at follow-up was associated with reduced symptom severity. MBSR did not significantly alter pain, physical functioning, or cortisol profiles. CONCLUSION: MBSR ameliorated some of the major symptoms of fibromyalgia and reduced subjective illness burden. Further exploration of MBSR effects on physiological stress responses is warranted. These results support use of MBSR as a complementary treatment for women with fibromyalgia ( ISRCTN: 34628811).

Diurnal cortisol rhythm as a predictor of lung cancer survival.

BACKGROUND: Poorly coordinated diurnal cortisol and circadian rest-activity rhythms predict earlier mortality in metastatic breast and colorectal cancer, respectively. We examined the prognostic value of the diurnal cortisol rhythm in lung cancer. METHODS: Lung cancer patients (n=62, 34 female) were within 5 years of diagnosis and had primarily non small-cell lung cancer, with disease stage ranging from early to advanced. Saliva collected over two days allowed calculation of the diurnal cortisol slope and the cortisol awakening response (CAR). Lymphocyte numbers and subsets were measured by flow cytometry. Survival data were obtained for 57 patients. Cox Proportional Hazards analyses were used to test the prognostic value of the diurnal cortisol rhythm on survival calculated both from study entry and from initial diagnosis. RESULTS: The diurnal cortisol slope predicted subsequent survival over three years. Early mortality occurred among patients with higher slopes, or relatively "flat" rhythms indicating lack of normal diurnal variation (Cox Proportional Hazards p=.009). Cortisol slope also predicted survival time from initial diagnosis (p=.012). Flattened profiles were linked with male gender (t=2.04, df=59, p=.046) and low total and cytotoxic T cell lymphocyte counts (r=-.39 and -.30, p=.004 and .035, respectively). After adjustment for possible confounding factors, diurnal slope remained a significant, independent predictor of survival. CONCLUSIONS: Flattening of the diurnal cortisol rhythm predicts early lung cancer death. Data contribute to growing evidence that circadian disruption accelerates tumor progression.
