Observational Study
Pain Severity and Pain Interference in Late Pregnancy: An Analysis of Biopsychosocial Factors among Women Scheduled for Cesarean Delivery.
Pain is a variably experienced symptom during pregnancy, and women scheduled for cesarean delivery, an increasingly common procedure, are a relatively understudied group who might be at higher pain risk. Although biopsychosocial factors are known to modulate many types of chronic pain, their contribution to late pregnancy pain has not been comprehensively studied. We aimed to identify biopsychosocial factors associated with greater pain severity and interference during the last week of pregnancy. ⋯ Independent of demographic or clinical factors, psychological factors, including depression, sleep disturbance, and pain catastrophizing, conferred a greater risk of late pregnancy pain. These findings suggest that women at higher risk of pain during late pregnancy could benefit from earlier nonpharmacological interventions that concurrently focus on psychological and pain symptoms.

Depression frequently coexists with chronic pain. Contemporary models suggest that these conditions share pathobiological mechanisms, prompting a need to investigate their temporal association. This investigation aimed to explore two distinctly different chronic pain conditions, and their cross-sectional and prospective associations with depression. ⋯ Pain may be a stressor from which depression can arise. Development of depression may be differentially dependant upon the type of pain experienced. Screening for depression symptoms among individuals with both chronic pain conditions is indicated and should be repeated over time.

Randomized Controlled Trial
Efficacy of Duloxetine in Patients with Central Post-Stroke Pain: A Randomized Double Blind Placebo Controlled Trial.
Central post-stroke pain (CPSP) refers to neuropathic pain in areas of the body corresponding to stroke lesions. Duloxetine, a serotonin-norepinephrine reuptake inhibitor, is safe and effective against neuropathic pain. In this randomized double-blind placebo-controlled study, we studied the effect of duloxetine in CPSP patients. ⋯ Duloxetine can be an effective treatment option for patients with moderate to severe central post-stroke pain.

Multicenter Study
Assessing validity of the original and Rasch versions of the central sensitization inventory with psychophysical tests in people with knee osteoarthritis.
To determine the extent of agreement between the original Central Sensitization Inventory (CSI) and the Rasch-calibrated version (RC-CSI) and to explore the association of both versions with psychophysical tests and their respective sensitivity and specificity. ⋯ Because of poor variance explained with psychophysical tests and high false positive rates, our results indicate that there is little clinical value of using either version of the CSI in people with knee osteoarthritis.
