Repeated stress produces hyperalgesic priming in preclinical models, but underlying mechanisms remain uncertain. As stress engages kappa opioid receptors (KORs), we hypothesized that repeated administration of KOR agonists might mimic, in part, stress-induced hyperalgesic priming. The potential contribution of circulating prolactin (PRL) and dysregulation of the expression of PRL receptor (PRLR) isoforms in sensory neurons after KOR agonist administration was also investigated. ⋯ Umbellulone-induced allodynia was prevented by cabergoline co-treatment during priming with KOR agonists in female, but not male, mice. Hyperalgesic priming therefore occurs in both sexes after either biased or nonbiased KOR agonists. However, a PRL/PRLR-dependence is observed only in female nociceptors possibly contributing to pain in stress-related pain disorders in females.

Randomized Controlled TrialOutpatient Treatment With Gabapentin in Women With Severe Acute Pain After Cesarean Delivery Is Ineffective: A Randomized, Double-Blind, Placebo-Controlled Trial.
Most of the 1.1 million women who deliver by cesarean in the United States each year have an uncomplicated recovery. However, severe pain resistant to standard multimodal therapy within the first days after surgery is associated with an increased risk for prolonged pain and opioid use. The best outpatient management for parturients with severe resistant early onset pain is not known. ⋯ Outpatient supplementation with gabapentin did not reduce time to opioid cessation, pain, anxiety, depression, fatigue, or improve physical function in women with severe pain after cesarean delivery. Gabapentin should not be routinely added to the standard outpatient multimodal regimen of ibuprofen, acetaminophen, and opioids.

Analgesia and Sedation at Terminal Extubation: A Secondary Analysis From Death One Hour After Terminal Extubation Study Data.
To describe the doses of opioids and benzodiazepines administered around the time of terminal extubation (TE) to children who died within 1 hour of TE and to identify their association with the time to death (TTD). ⋯ Children after TE are often prescribed opioids and benzodiazepines. For patients dying within 1 hour of TE, TTD is not associated with the dose of medication administered as part of comfort care.

Opioid-related promotional payments are associated with increased prescribing of the promoted drug, but little is known about whether physicians receiving payments influence peers to accept similar payments. ⋯ Our study demonstrates that physicians receiving opioid-related payments are more likely to cluster within physician networks.
