Buprenorphine, a partial opioid agonist, has emerging evidence as an alternative to full agonist opioids for treatment of acute pain. This systematic review aimed to evaluate the safety and efficacy of buprenorphine for acute pain in older adults. ⋯ This review did not find buprenorphine to be superior to alternative analgesia; however the mixed results provide scientific rationale for future studies testing buprenorphine in older populations.

Patients with chronic pain disorders, including Temporomandibular Disorders (TMDs) endorse high levels of sleep disturbances, frequently reporting reduced sleep quality. Despite this, little is known about the effect that daytime pain has on the microstructure and macro-architecture of sleep. Therefore, we aimed to examine the extent to which daytime pain sensitivity, measured using quantitative sensory testing (QST), is associated with objective sleep parameters the following night, including sleep architecture and power spectral density, in women with TMD. ⋯ Our findings demonstrate that higher generalized pain sensitivity, masseter pain pressure threshold, as well as central sensitization were associated with a lower percentage of REM in participants with myofascial pain and arthralgia of the masticatory system. These findings provide an important step toward understanding the mechanistic underpinnings of how chronic pain interacts with sleep physiology.
