Depression in Korean immigrants with hepatitis B and related liver diseases.

The authors evaluated 50 Korean immigrants who had chronic viral hepatitis or who were healthy carriers for the hepatitis B virus in terms of the relationships between their depression scores, psychosocial stressors, social support, and biological markers of dysfunction. All participants completed a questionnaire, describing their worries and concerns, and the shortform of the Beck Depression Inventory (BDI-sf). Hepatic transaminases, albumin levels, and prothrombin times were measured during routine clinic follow-up visits and were abstracted from the medical record. Values recorded within 3 months before and within 3 months after the psychiatric interview were correlated with BDI scores. BDI-sf total scores were significantly associated with transaminase elevations (P<0.001) both before and after BDI-sf administration. BDI scores were not associated with other measures of liver dysfunction or other medical causes of depression. Patients with higher BDI-sf total scores had more psychosocial stressors (P = 0.008) and lower Global Assessment of Functioning (GAF) scores (P = 0.000).

Constant observation practices in the general hospital setting: a national survey.

The authors conducted a national survey of 355 general medical/surgical hospitals to assess constant observation (CO) practices. The authors assessed overall use, expense, staffing patterns, funding strategies, and cost-saving interventions. Virtually all responding hospitals (N = 102) reported using some form of CO. Several hospitals reported significant decreases in CO expenditures after the implementation of cost-saving interventions (the largest annual decrease reported was $340,000). Cost-saving interventions included utilizing consolidated bed spaces, relocating patients near nursing stations, placing at-risk patients in bed enclosure devices, and regularly assisting patients to the toilet. In addition, less costly personnel were hired, and volunteers and/or patient family members provided CO (or were required to assist with the cost of CO). Finally, hospital staff were educated about the costs and the appropriate use of CO. They were also taught to recognize and effectively treat delirium.

Self-reported sleep quality and quality of life for individuals with chronic pain conditions.

OBJECTIVE: To determine the sleep quality and quality of life for individuals with degenerative spinal disease or failed back surgery syndrome. DESIGN: Cross-sectional survey design utilizing standardized instruments. Data were analyzed with use of hierarchical stepwise multiple regression analyses. PATIENTS: One hundred sixty-seven individuals with degenerative spinal disease or postlaminectomy syndrome who presented to a tertiary care outpatient patient pain center. OUTCOME MEASURES: The Center for Epidemiological Studies Depression Index measured depressive symptomatology. A modified Pittsburgh Sleep Quality Index (PSQI) measured sleep quality. The arithmetic average of least and usual VAS ratings of pain measured everyday pain. A visual analog scale rating of highest pain during the past 2 weeks measured highest pain. The Epworth Sleepiness Scale measured daytime sleepiness. The Medical Outcome Study-Short Form-Health Survey (SF-36) measured the mental health and general health components of quality of life. RESULTS: Higher overall sleep quality and lower sleep latency primarily were related to higher ratings of physical functioning and shorter duration of pain. Ratings of the highest pain, but not everyday pain, were independent predictors of overall sleep quality and sleep latency. Daytime sleepiness was associated with younger age and depressed mood. Pain was not associated independently with daytime sleepiness. The quality of life related to mental functioning was associated positively with depressed mood and with the interaction of pain and depressed mood. None of the variables in the model (i.e., pain intensity, sleep quality, depression, and demographic variables) predicted quality of life related to overall general health. CONCLUSIONS: These data suggest that physical functioning, duration of pain, and age may be more important than pain intensity and depressed mood in contributing to decreased overall sleep quality and sleep latency. The contribution of physical functioning was particularly strong and should be included in subsequent studies of sleep, pain, and mood. The SF-36 should be compared to pain-specific quality-of-life measures to further evaluate the usefulness of this instrument with outpatients with chronic nonmalignant pain conditions.

Sleep disturbance and nonmalignant chronic pain: a comprehensive review of the literature.

Sleep disturbance is an important clinical complaint for individuals with nonmalignant pain conditions. This review is a broad introduction to the literature on sleep disturbance and chronic pain conditions. The article critically reviews studies of sleep disturbance in musculoskeletal pain, arthritis, headache, and fibromyalgia. Current neurobiological hypotheses regarding the pathogenesis of sleep disturbance and chronic pain, common comorbid disorders, and pharmacologic and non-pharmacologic treatments for sleep disturbance are reviewed.

Outcome of chronic opioid therapy for non-cancer pain.

Potential iatrogenic mood and cognitive declines associated with long-acting opioid therapy were examined in 19 patients receiving long-acting oral opioid medications and compared to ten patients receiving usual care. Pain, mood, and cognitive function were measured before and after achieving stable doses. In addition to reducing pain, long-acting opioid medication reduced anxiety and hostility. No declines in cognitive function were associated with the long-acting opioid medications, and the group receiving long-acting opioid medications showed significant improvement on a measure of psychomotor speed and sustained attention. Both patient groups reported significant reductions in perceived impairment in daily activities due to pain. Treatment responders taking long-acting opioid medications (63%) were taking a significantly lower dose at follow-up than the treatment non-responder group. These findings suggest that long-acting opioid medications can improve mood and do not impair cognitive functioning in patients with chronic non-cancer pain.
