To examine sleep disturbances in the POINT cohort study consisting of participants prescribed long-term opioids for chronic noncancer pain (CNCP), and to examine the relationship between sleep and measures of pain, physical and mental health, substance use, and medication use at the baseline interview. ⋯ High levels of sleep problems were reported in this community sample of CNCP patients prescribed long-term opioids, and were associated with mental health problems and increased medication use. Nonmedication approaches to addressing sleep problems should be prioritized in this population.

Minalcipran has been approved for the treatment of fibromyalgia in several countries including Australia. Australian agency considered that the overall efficacy is moderate, although clinically significant, and could be translated into a real and strong improvement in some patients. The determination of the characteristics of patients who could benefit the most from milnacipran (MLN) is the primary objective of this manuscript. ⋯ Clustering and predictive data-mining methods provide additional insight about fibromyalgia, its symptoms, and treatment. The information is useful to physicians to optimize prescriptions in the daily practice and to regulatory bodies to refine indications.

Mental defeat has been implicated in precipitating suicide with effects not explained by depression. It has also been found to be elevated in people who are most distressed and disabled by chronic pain. This study examined the role of mental defeat in predicting suicide intent among chronic pain patients and compared the predictive value of mental defeat with other established pain and psychological constructs. ⋯ Mental defeat may be a key indicator for heightened suicide risk. Therapeutic interventions targeting mental defeat offer a novel avenue for reducing suicide risk in chronic pain patients.

Pregabalin Improves Fibromyalgia-Related Sleep Disturbance.
To investigate the effect of pregabalin on wake and sleep bout parameters. ⋯ Pregabalin improved sleep parameters characteristic of disturbed sleep in FM, by preventing awakenings and increasing sleep bout duration. These effects are reflected in, and correlated with, a decrease in "light sleep" (stage 1) and an increase in "deep sleep" (slow wave sleep).
