Randomized Controlled Trial Multicenter Study
Short-term effects of bright light therapy in adults with chronic nonspecific back pain: a randomized controlled trial.
The present trial evaluated incorporation of bright light therapy in the treatment of chronic nonspecific back pain (CNBP). ⋯ The present randomized controlled trial shows that light therapy even in low dose could improve depressive symptoms and reduce pain intensity in CNBP patients. Further research is needed for optimizing parameters of frequency, dose, and duration of therapeutic light exposure.

Randomized Controlled Trial
Baseline brain activity predicts response to neuromodulatory pain treatment.
The objective of this study was to examine the associations between baseline electroencephalogram (EEG)-assessed brain oscillations and subsequent response to four neuromodulatory treatments. Based on available research, we hypothesized that baseline theta oscillations would prospectively predict response to hypnotic analgesia. Analyses involving other oscillations and the other treatments (meditation, neurofeedback, and both active and sham transcranial direct current stimulation) were viewed as exploratory, given the lack of previous research examining brain oscillations as predictors of response to these other treatments. ⋯ The findings support the idea that different patients respond to different pain treatments and that between-person treatment response differences are related to brain states as measured by EEG. The results have implications for the possibility of enhancing pain treatment response by either 1) better patient/treatment matching or 2) influencing brain activity before treatment is initiated in order to prepare patients to respond. Research is needed to replicate and confirm the findings in additional samples of individuals with chronic pain.

To investigate the role of preoperative pain sensitivity and preoperative symptom severity for prediction of postoperative pain intensity after lumbar spine surgery. ⋯ The study highlights that each preoperative back pain and individual pain sensitivity could predict the different aspects of postoperative pain after lumbar surgery.

A migraine is a common neurological disorder that often coexists with other illnesses including heart abnormalities, such as patent foramen ovale (PFO), atrial septal aneurysm (ASA), and mitral valve prolapse (MVP). ⋯ The results of our study raise the question of the heart's role in the mechanism of migraine attacks. If the occurrence of migraine with aura had been related to some heart abnormalities, the pathophysiology of migraine attacks may have some connection to some heart dysfunction. Resolving the association between migraine and comorbid cardiac conditions might shed light on the underlying mechanisms of migraines and even result in a different treatment strategy. However, we do not find any clear connection between PFP, ASA, and MVP, and migraine occurrence.

Opioid-induced respiratory depression (OIRD) is a life-threatening complication of opioid therapy in children. Naloxone administration triggered by OIRD has been used to monitor safety of opioid therapy in adults. We used this trigger as a quality measure of opioid safety in hospitalized children to identify risk predictors of OIRD. ⋯ OIRD is an important, albeit mostly preventable, complication of opioid therapy in children. Naloxone use can be used as a measure to track opioid safety in children, identify contributing factors, and formulate preventive strategies to reduce the risk for OIRD.
