Randomized Controlled Trial
Auricular acupressure for analgesia in perioperative period of total knee arthroplasty.
We examined whether auricular acupressure (AA) can alleviate postoperative pain and decrease narcotic consumption and its adverse effects for osteoarthritis patients after total knee arthroplasty (TKA). ⋯ Applying auricular acupoint acupressure in the perioperative period of TKA is favorable for alleviating postoperative pain, decreasing opioid consumption and its adverse effects, and promoting early rehabilitation. Also, this intervention has the advantage of lower costs, fewer complications, simple application, and high safety.

Research has shown significant rates of comorbidity among posttraumatic stress disorder (PTSD), major depressive disorder (MDD), and pain in prior era veterans but less is known about these disorders in Iraq and Afghanistan war era veterans. This study seeks to extend previous work by evaluating the association among PTSD, MDD, and pain (back, muscle, and headache pain) in this cohort. ⋯ Findings highlight the complex comorbid relationship between PTSD, MDD, and pain among Iraq and Afghanistan veterans. This observed association suggests that integrated, multidisciplinary treatments may be beneficial, particularly when multiple psychological and physical health comorbidities are present with pain. Further support may be indicated for ongoing education of mental health and primary care providers about these co-occurring disorders.

To describe the level of knowledge, attitudes, and self-reported quality of practice in pain assessment among nurses of Mainland China and explore links with current hospital pain policy and continuing education. ⋯ This study identified inadequate knowledge and low level of self-reported pain assessment practice among nurses working in high-level hospitals in Mainland China. Current education did not influence nursing self-reported pain assessment practice. Knowledge of pain evaluation should be improved through newer approaches to education. A better policy framework for pain evaluation may also contribute to improvement.

To investigate whether bilateral deep tissue pressure hyperalgesia exists in individuals with unilateral thumb carpometacarpal osteoarthritis (CMC OA). ⋯ This study revealed bilateral localized pressure pain hypersensitivity over the hand in individuals with unilateral thumb CMC OA, suggesting spinal cord sensitization mechanisms in this population. Future studies should analyze the presence of widespread pressure pain sensitivity in patients with thumb CMC OA to further determine the presence of central sensitization mechanisms.

There is an unmet clinical need for novel analgesics for neuropathic pain. This study was designed to elucidate the mechanism through which EMA300, a small molecule antagonist of the angiotensin II type 2 receptor (AT₂R) with >1,000-fold selectivity over the angiotensin II type 1 receptor, produces analgesia in a rodent model of neuropathic pain. ⋯ Augmented angiotensin II/AT₂R signaling in the DRGs of CCI rats is attenuated by EMA300 to block p38 MAPK and p44/p42 MAPK activation, a mechanism with clinical validity for alleviating neuropathic pain.
