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.

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.

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.

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.

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.

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.
