Little systematic research has been conducted to understand pain among persons with end-stage liver disease, especially among liver transplant candidates. Appropriate pain assessment and management are important areas of consideration as treatment options are limited. ⋯ Pain is a significant problem among liver transplant candidates, and current pain treatments are perceived to be relatively ineffective. Increased understanding is needed to safely and effectively evaluate and treat such medically complicated patients.

Methadone in the chronic pain patient with a substance use disorder.
Methadone, used both to treat opioid addiction and to manage chronic pain, is commonly prescribed as an opioid of choice for patients with chronic pain and comorbid substance use disorders. This practice apparently derives from the belief that because methadone is widely used in opioid addiction treatment programs, it is an excellent choice for the management of chronic pain in individuals with substance use disorders. However, chronic pain and addiction treatment contexts are vastly different. ⋯ Methadone is a uniquely complex opioid, responsible for a disproportionate percentage of opioid-related morbidity and mortality. Its use in high-risk patients should not be a reflexive choice. Rather, it should be employed only after careful consideration of relative risks and benefits.

Psychological factors are thought to play a part in the aetiology of chronic widespread pain. We investigated the relationship between intelligence in childhood and risk of chronic widespread pain in adulthood in 6902 men and women from the National Child Development Survey (1958 British Birth Cohort). Participants took a test of general cognitive ability at age 11 years; and chronic widespread pain, defined according to the American College of Rheumatology criteria, was assessed at age 45 years. ⋯ In multivariate backwards stepwise regression, lower childhood intelligence remained as an independent predictor of chronic widespread pain (RR 1.10; 95% CI 1.01-1.19), along with social class, educational attainment, body mass index, smoking status, and psychological distress. Part of the effect of lower childhood intelligence on risk of chronic widespread pain in midlife was significantly mediated through greater body mass index and more disadvantaged socioeconomic position. Men and women with higher intelligence in childhood are less likely as adults to report chronic widespread pain.

Randomized Controlled Trial
Associations between daily chronic pain intensity, daily anger expression, and trait anger expressiveness: an ecological momentary assessment study.
Links between elevated trait anger expressiveness (anger-out) and greater chronic pain intensity are well documented, but pain-related effects of expressive behaviors actually used to regulate anger when it is experienced have been little explored. This study used ecological momentary assessment methods to explore prospective associations between daily behavioral anger expression and daily chronic pain intensity. Forty-eight chronic low back pain (LBP) patients and 36 healthy controls completed electronic diary ratings of momentary pain and behavioral anger expression in response to random prompts 4 times daily for 7 days. ⋯ Overlap with trait and state negative affect did not account for study findings. This study for the first time documents lagged within-day influences of behavioral anger expression on subsequent chronic pain intensity. Trait anger regulation style may moderate associations between behavioral anger expression and chronic pain intensity.

Chronic pain is currently considered a public health problem with high costs to the individual and society. To improve prevention and treatment of chronic pain, epidemiologic studies are mandatory for assessing chronic pain. The aims of this study were to estimate the prevalence of chronic pain in the adult Danish population and to analyze associated factors such as diseases, immigration, and opioid use. ⋯ The study population consisted of 14,925 individuals in whom a high prevalence of chronic pain (26.8%, 95% confidence interval: 26.1 to 27.5) and a high prevalence of opioid consumption (4.5%) were observed. Other aspects of particular note: (1) a higher prevalence of chronic pain occurred among individuals with cardiovascular and chronic pulmonary diseases than among individuals with cancer; and (2) individuals with a non-Western background reported a higher pain prevalence, higher pain intensities, and more widespread pain than individuals with Danish background; however, opioids were more frequently used by native Danes. The prevalence of chronic pain as well as opioid use in Denmark are alarmingly high, and the relevance of opioid consumption is unknown.
