Postpartum pain during intercourse is a prevalent and distressing problem that has substantial consequences for affected couples. Partner perceptions-such as how partners perceive women's pain self-efficacy-contribute to an individual's pain experience. This study examined whether partners under- or over-estimate women's intercourse pain self-efficacy at 3-months postpartum and the implications of this bias for women's pain and couples' sexual functioning at 3- and 6-months postpartum. ⋯ Findings may inform interventions that promote pain self-efficacy to improve partner support and couples' sexual functioning. PERSPECTIVE: When women report-and their partners perceive-low levels of women's self-efficacy for managing painful intercourse, women report greater postpartum pain during intercourse and couples indicate poorer sexual functioning. These findings suggest that interventions aimed at promoting couples' agreement at high pain self-efficacy may improve their adjustment to postpartum pain.

Pain is a pervasive problem that affects nearly half of the U. S. Veterans deployed in support of the Global War on Terror (Post-9/11 Veterans) and over half of the Post-9/11 Veterans with diagnosed traumatic brain injury (TBI). ⋯ PERSPECTIVE: The complexity of pain in patients with mTBI is categorically different than those with no TBI. Pain in patients with mTBI is heterogeneous with distinct phenotypes which may explain poor outcomes in this group. Identification of the individual differences may have a significant impact on the success of interventions.

Comparative Study
Sensitivities to Thermal and Mechanical Stimuli: Adults with Sickle Cell Disease Compared to Healthy, Pain-free African American Controls.
Evidence supports, but is inconclusive that sensitization contributes to chronic pain in some adults with sickle cell disease (SCD). We determined the prevalence of pain sensitization among adults with SCD pain compared with pain-free healthy adults. In a cross sectional, single session study of 186 African American outpatients with SCD pain (age 18-74 years, 59% female) and 124 healthy age, gender, and race matched control subjects (age 18-69 years, 49% female), we compared responses to standard thermal (Medoc TSA II) and mechanical stimuli (von Frey filaments). ⋯ Findings indicate that persistent allodynia and hyperalgesia can be part of the SCD pain experience and should be considered when selecting therapies for SCD pain. PERSPECTIVE: Compared with matched healthy controls, quantitative sensory testing in adults with pain and sickle cell disease (SCD) demonstrates higher prevalence of sensitization, including central sensitization. The findings of allodynia and hyperalgesia may indicate neuropathic pain and could contribute to a paradigm shift in assessment and treatment of SCD pain.

Complex regional pain syndrome (CRPS) results in chronic and excruciating pain in patients. Conventional therapies lack effectiveness, rendering it one of the most difficult to treat neurological conditions.. Electroacupuncture (EA) is an effective alternative therapy for pain relief. ⋯ PERSPECTIVE: Our work identified that EA exerts robust antiallodynic effect on an animal model of CRPS-I, via mechanisms involving inhibition of CXCL12/CXCR4 signaling. EA further attenuates downstream neuronal and glial cell activation and ERK pathway in SCDH. This work suggests that EA may be a potential therapeutic option for CRPS-I management in clinic.

The opioid crisis has highlighted the importance of improving patients' access to behavioral treatments for chronic pain and addiction. What is not known is if patients are interested in receiving these treatments. In this cross-sectional study, over 1,000 participants with chronic pain were surveyed using an anonymous online questionnaire on Amazon Mechanical Turk to investigate participants' use of and interest in pharmacological and behavioral treatments for chronic pain and addiction. ⋯ Results also suggest that patients endorsing behaviors consistent with opioid misuse are interested in behavioral treatments. PERSPECTIVE: This study provides information around chronic pain patients' treatment interests, treatment receipt, and recommendation receipt for behavioral pain management and addiction treatment. This study could help facilitate communication between patients and doctors regarding available treatments for chronic pain and pain treatment-related addiction problems.
