Obstructive sleep apnea syndrome and postoperative complications: clinical use of the STOP-BANG questionnaire.

Objective: To determine whether high risk scores on preoperative STOP-BANG (Snoring, Tiredness during daytime, Observed apnea, high blood Pressure, Body mass index, Age, Neck circumference, Gender) questionnaires during preoperative evaluation correlated with a higher rate of complications of obstructive sleep apnea syndrome (OSAS).

Design: Historical cohort study.

Setting: Thomas Jefferson University Hospital, Philadelphia, Pennsylvania.

Women at a dangerous intersection: diagnosis and treatment of depression and related disorders in patients with breast cancer.

Breast cancer is a relatively common diagnosis for American women and depressive symptoms occur in many women with breast cancer. Identification of women with breast cancer and concomitant depressive symptoms and mood disorders requires particular attention by heath care providers, and may be aided by the administration of a variety of diagnostic and/or screening tools. Insomnia is also a significant problem for women with breast cancer at various stages of diagnosis and treatment, including after remission.

Hematologic problems in psychosomatic medicine.

Vitamin B12 deficiency is associated with problems in cognition, mood, psychosis, and less commonly, anxiety. Folate deficiency primarily is associated with problems in mood. Patients who have sickle cell disease, a disease of chronic pain, experience difficulties with depression, anxiety, stigma, and are at risk for substance abuse and dependence.

Normal sleep and circadian rhythms: neurobiologic mechanisms underlying sleep and wakefulness.

Sleep is a vital, highly organized process regulated by complex systems of neuronal networks and neurotransmitters. Sleep plays an important role in the regulation of central nervous system and body physiologic functions. Sleep architecture changes with age and is easily susceptible to external and internal disruption.

Update on parasomnias: a review for psychiatric practice.

Parasomnias, defined as undesirable behavioral, physiological, or experiential events that accompany sleep, are common in the general population. As a rule, they occur more frequently in children than in adults with the exception of REM sleep behavior disorder (RBD), which is more common in men over 50. No longer considered to be invariably a sign of psychopathology, parasomnias are currently understood as clinical phenomena that arise as brain transitions between REM sleep, non-REM sleep, and wakefulness.

Sleep-disordered breathing: in depression and schizophrenia.

Sleep disorders are becoming more prevalent. There is an overlap of symptoms related to obstructive sleep apnea syndrome (OSAS) and many psychiatric conditions. Complaints of excessive sleepiness, insomnia, cognitive dysfunction, and depressive symptoms can be related to both disease states.

The impact of anxiety and mood disorders on physical disease: the worried not-so-well.

Depression and anxiety can adversely affect the course of chronic physical illnesses, increasing morbidity and mortality. The literature during the past year is reviewed for gastrointestinal disorders, cancer, pain, heart disease, diabetes, and pulmonary disease. Causes for this relationship are behavioral and biological.
