Randomized Controlled Trial
Exposure and cognitive-behavioral therapy for chronic back pain: an RCT on treatment processes.
To improve treatment outcomes, it is essential to understand the processes involved in therapeutic change. The aim of this study was to investigate the processes involved in treatment of individuals with chronic lower back pain (CLBP) and high fear-avoidance. Graded in vivo exposure (Exposure), a specific treatment, and cognitive-behavioural therapy (CBT), a general treatment, were compared. ⋯ We identified several treatment processes (e.g., reduction of fear of movement, enhancement of self-efficacy), which were associated with disability reduction during the management of chronic pain and fear-avoidance. These processes appeared to be equally important for Exposure and CBT. Practitioners should optimize these processes to improve their patients' functioning.

The antineoplastic drugs cisplatin and vincristine induce peripheral neuropathies. The sigma-1 receptor (σ1R) is expressed in areas of pain control, and its blockade with the novel selective antagonist MR-309 has shown efficacy in nociceptive and neuropathic pain models. Our goal was to test whether this compound reduces neuropathic signs provoked by these antitumoural drugs. ⋯ σ1R antagonism could be an interesting and new option to palliate antitumoural neuropathies.

Ocular surface diseases are among the most frequent ocular pathologies. Ocular pain following corneal injury is frequently observed in clinic. Corneal sensory innervation is supplied by ciliary nerves derived from ophthalmic division of the trigeminal ganglion. ⋯ This study highlights the parallel increase in ciliary nerve activity and corneal sensitivity after corneal injury in mice. The strategy of combining ex vivo electrophysiological recordings of the ciliary nerve in mice and corneal sensitivity measurements therefore helps to uncover the functional aspects of corneal pain.

Randomized Controlled Trial
Economic evaluation of a healthy lifestyle intervention for chronic low back pain: A randomized controlled trial.
Economic evaluations which estimate cost-effectiveness of potential treatments can guide decisions about real-world healthcare services. We performed an economic evaluation of a healthy lifestyle intervention targeting weight loss, physical activity and diet for patients with chronic low back pain, who are overweight or obese. ⋯ This is an economic evaluation of a randomized controlled trial of a healthy lifestyle intervention for chronic low back pain. The findings suggest that a healthy lifestyle intervention may be cost-effective relative to usual care.

Individuals born preterm are at risk of later developmental problems and long-term morbidities. There is conflicting evidence regarding musculoskeletal pain in young adulthood. We investigated the prevalence of self-reported musculoskeletal pain in young adults born across the range of preterm birth compared with a term-born reference group. ⋯ Young adults born preterm do not have increased rates of musculoskeletal pain. Our findings rather suggest that these rates may be slightly lower than among those born at term.
