Emotional approach coping (EAC) is a potentially adaptive emotion-focused coping style that involves understanding or processing one's emotions and expressing them appropriately. Although EAC has been studied in various populations, little is known about this construct among people with chronic pain, including potential mediators such as negative affect, which might link EAC to pain-related variables, and moderators of these relationships. ⋯ EAC is associated with lower pain intensity in young/middle-age adults and lower pain interference in women, and lower negative affect mediates these relationships. These results suggest the potential value of assessing and bolstering emotional approach coping processes in some people with chronic pain.

Review Meta Analysis
Systemic inflammatory markers in neck pain: a systematic review with meta-analysis.
Mechanisms underpinning symptoms in non-traumatic neck pain (NTNP) and whiplash-associated disorder (WAD) are not comprehensively understood. There is emerging evidence of systemic inflammation in musculoskeletal pain conditions, including neck and back pain. The aim of this systematic review was to determine if raised blood inflammatory markers are associated with neck pain. ⋯ This systematic review advances our understanding of neck pain pathophysiology by demonstrating the presence of systemic inflammation in chronic neck pain, in the form of raised IL-1β and TNFα. Further, numerous inflammatory markers were associated with clinical variables, including pain intensity, disability and hyperalgesia. These findings imply that systemic inflammation may contribute to mechanisms underlying neck pain.

Review Meta Analysis
The response-time relationship and covariate effects of acupuncture for chronic pain: a systematic review and model-based longitudinal meta-analysis.
Critical clinical questions regarding how soon and how long the analgesic effect will be achieved by acupuncture, as well as who will be responsive to acupuncture, need further address. The aim of the study was to investigate the response-time relationship and covariate effects of acupuncture. ⋯ Our systematic review and meta-analysis provides the clear evidence for the treatment duration and significant related covariates of acupuncture intervention for chronic pain. These results provide useful suggestion for acupuncture intervention in clinical pain management.

The aim of this study was (a) to statistically identify distinct trajectories of pain following surgery in infants less than 6 months of age, and (b) to compare these trajectories to descriptions of chronic pain in infants in the neonatal intensive care unit (NICU). ⋯ This study has revealed two distinct pain trajectories in infants after surgery. While recovery from pain occurs within days in the typical group, the atypical group demonstrates pain for a significantly longer period, often weeks and months following surgery. This latter group adheres closely to current descriptions of chronic pain in infants.

Movement and posture are commonly believed to relate to non-specific low back pain (NSLBP). While people with NSLBP appear to move and posture themselves differently from those without NSLBP, changes in movement and posture infrequently relate to improvements in NSLBP when analysed at a group-level. Additionally, little is known about how movement or posture change when clinical outcome improves. ⋯ Changes to individually relevant movement and posture appear to often relate to clinical outcome, but not always. Patient-specific activities, and movement or postural parameters that related to improved pain and activity limitation, varied across the 12 participants, highlighting the potential importance of individualised management. Where clinical improvements were related to changes in movement or posture, participants consistently returned towards being 'less protective' (increased range and speed of movement, increased posterior-pelvic-tilt during sitting and standing). Mechanisms and generalizability remain unclear.
