Multicenter Study
Negative mood mediates the effect of poor sleep on pain among chronic pain patients.
Sleep disturbances and increased negative mood are common among chronic pain patients. Research suggests that sleep disruption can contribute to increased pain; however, the role of negative mood in this relationship is unclear. The present study investigated the relationship among sleep disturbance, negative mood, and pain within a large sample of chronic pain patients. It was hypothesized that negative mood would mediate the relationship between sleep and pain. ⋯ These findings suggest that addressing negative mood directly, or by addressing sleep disturbances in chronic pain patients, may have a beneficial impact on patients' pain. As sleep disturbance may be causing negative mood, treating the sleep disturbance may also be beneficial among chronic pain patients. Negative mood may perpetuate the impact of sleep disturbances on pain, possibly through increased arousal or disruptions in diurnal patterns.

Clinical Trial
The use of opioids for breakthrough pain in acute palliative care unit by using doses proportional to opioid basal regimen.
To determine the efficacy and safety of different opioids used in doses proportional to the basal opioid regimen for the management of breakthrough pain (BP). ⋯ This survey suggests that doses of opioids for BP proportional to the basal opioid regimen, are very effective and safe in clinical practice, regardless the opioid and modality used.

Pain after breast cancer therapy is a recognized complication found to have an adverse impact on patient's quality of life, increasing psychosocial distress. In recent years, case reports about myofascial pain syndrome are emerging in thoracic surgery as a cause of postsurgery pain. Myofascial pain syndrome is a regional pain syndrome characterized by myofascial trigger points in palpable taut bands of skeletal muscle that refers pain a distance, and that can cause distant motor and autonomic effects. ⋯ Myofascial pain syndrome is a common source of pain in women undergoing breast cancer surgery that includes axillary lymph node dissection at least during the first year after surgery. Myofascial pain syndrome is one potential cause of chronic pain in breast cancer survivors who have undergone this kind of surgery.

Prevention of occupational low back pain (LBP) in nurses is a research priority. Recent research suggests intervening before commencing nursing employment is ideal; however, identification of modifiable risk factors is required. The objective of this study was to investigate modifiable personal characteristics that predicted new-onset LBP in nursing students. ⋯ Modifiable personal characteristics across multiple domains are associated with new-onset LBP in female nursing students. These findings may have implications for the development of prevention and management interventions for LBP in nurses.

Fibromyalgia syndrome (FMS) is a chronic disorder defined by widespread muscle pain and multiple tender points. The objectives of this study were to estimate prevalence of comorbidities, healthcare resources utilization, and costs associated with FMS. ⋯ Results of this analysis of the RAMQ database illustrate the high prevalence of comorbidities among patients with a diagnosis of FMS and strongly indicate that the economic burden of FMS is substantial.
