The aim of this systematic review was to provide a picture of suicidality (suicide ideation and behavior, both fatal and nonfatal) among indviduals with migraine. ⋯ Research has empirically documented a link between migraine and suicide ideation and behavior, particularly concerning the subtype of migraine with aura. Overall, nonfatal suicidal behavior among people with migraine has primarily been investigated, with only 2 studies analyzing suicide mortality. In addition, majority of studies originated from the United States or Canada (n=10). Future research should thoroughly define migraine and investigate link between migraine and suicide mortality.

The purpose of this study was to determine whether pain at hospital discharge is associated with general health and depression and posttraumatic stress disorder (PTSD) at 1 year following traumatic orthopedic injury. ⋯ Findings highlight the importance of early screening for uncontrolled postoperative pain to identify patients at high risk for poor psychological outcomes and who could benefit from more aggressive pain management. Results suggest early interventions are needed to address pain severity in patients with orthopedic trauma.

Randomized Controlled Trial Multicenter Study
Safety and Efficacy of Needle-Free Powder Lidocaine Delivery System in Adult Patients Undergoing Venipuncture or Peripheral Venous Cannulation: Randomized, Double-blind, Placebo-controlled Trial.
The purpose of this study was to evaluate the efficacy, safety, and tolerability of a needle-free powder lidocaine delivery system compared with sham placebo in adults. ⋯ This clinical trial demonstrated that use of a needle-free powder lidocaine delivery system resulted in a significant reduction of pain during venipuncture and peripheral intravenous cannulation in adults. Both the predefined primary endpoint and all 3 secondary endpoints were met. The needle-free powder lidocaine delivery system may be an option for analgesia during venous access procedures in adults.

Multicenter Study
Chronic Pain and Heart Rate Variability in a Cross-Sectional Occupational Sample: Evidence for Impaired Vagal Control.
The vagus nerve influences the modulation of pain. Chronic pain is associated with disturbance of the descendent inhibitory pathway (DIP). Heart rate variability (HRV) is a proxy measure for vagal activity and may reflect dysfunction of the DIP. We aimed to investigate the association of HRV and pain in individuals with and without chronic pain. ⋯ Our results suggest that the DIP indexed by vagal activity operationalized as RMSSD is disturbed in persons with chronic pain. Furthermore, the correlations between RMSSD and pain are different between those without and those with chronic pain. The findings are discussed, emphasizing changes in brain activity and the comorbid dysregulation of emotion in patients with chronic pain, to provide implications for the treatment of chronic pain.

Multicenter Study Observational Study
Pain-related Sleep Disturbance - A Prospective Study with Repeated Measures.
Pain has been found to be associated with poor sleep quality, awakenings, and shorter sleep time. There is a need to understand the relationship of pain and sleep over time to adequately manage the pain disorder and its consequences. The objectives of this study were to establish the prevalence of sleep disturbance in patients with acute or persistent low back pain (LBP), to investigate the correlation between pain and sleep disturbance and to explore the influence of pain on sleep disturbance. ⋯ This study used repeated measures of both pain and sleep disturbance. The results were in line with previous research, confirming that sleep disturbance was found in the majority of patients with LBP. Pain and sleep measures were significantly correlated, and there was an increased risk of reporting sleep disturbance after experiencing LBP.
