Multicenter Study
Physical health after childbirth and maternal depression in the first 12 months post partum: results of an Australian nulliparous pregnancy cohort study.
to investigate the relationship between maternal physical health problems and depressive symptoms in the first year after childbirth. ⋯ poor physical health in the early postnatal period is associated with poorer mental health throughout the first 12 months post partum. Early intervention to promote maternal mental health should incorporate assessment and intervention to address common postnatal physical health problems.

ReviewPatient selection for spinal cord stimulators: mental health perspective.
Research has shown that psychosocial factors can predict poor outcome for spinal cord stimulation (SCS) for patients with chronic pain, substantiating the need for standardized assessment techniques to incorporate psychosocial factors in patient selection. Presurgical psychological assessment is often required for SCS. ⋯ In addition, psychologists take part in preparing patients who were initially deemed unsuitable for SCS by providing recommendations and potential access to clinical care addressing psychological issues in chronic pain. Barriers to presurgical psychological assessments include limited access to skilled psychologists and issues with feasibility and appropriateness of standardized measures, and further work is needed to improve standardized methodology.

Chronic back pain is globally acknowledged as a common reason why people seek help from health professionals. The complexity of persistent chronic pain can undermine the person's self-esteem and present a number of challenges to an individual's ability to manage their pain. Multi-professional person-centered care is advocated as a key strategy to support people with chronic back pain. ⋯ These categories formed the "conditional partnership" as a theory to explain person-centered care, which related to the way in which the partnership developed between the patients and teams. The findings suggest that person-centered care was influenced by the participants' need to be believed and the relationship developed with health care providers. Crucially, these findings suggest that legitimizing the pain experience through person-centered approaches to care can empower people with chronic back pain to regain control of their lives and their pain.

Comparative Study
Intervertebral discs from spinal nondeformity and deformity patients have different mechanical and matrix properties.
It is well-established that disc mechanical properties degrade with degeneration. However, prior studies utilized cadaveric tissues from donors with undefined back pain history. Disc degeneration may present with pain at the affected motion segment, or it may be present in the absence of back pain. The mechanical properties and matrix quantity of discs removed and diagnosed for degeneration with patient chronic pain may be distinct from those with other diagnoses, such as spinal deformity. ⋯ Our data suggest that discs from nondeformity discs have subtle differences in mechanical properties compared with deformity discs. These differences were partially explained by matrix biochemical composition for the annulus, but not for the nucleus. The results of this study suggest that compromised matrix quality and diminished mechanical properties are features that potentially accompany discs of patients undergoing segmental fusion or disc replacement for disc degeneration and chronic back pain. These features have previously been implicated in pain via instability or reduced motion segment stiffness.

The hippocampus has been shown to undergo significant changes in rodent models of neuropathic pain; however, the role of the hippocampus in human chronic pain and its contribution to pain chronification have remained unexplored. Here we examine hippocampal processing during a simple visual attention task. We used functional MRI to identify intrinsic and extrinsic hippocampal functional connectivity (synchronous neural activity), comparing subacute back pain (SBP, back pain 1-4 mo) and chronic back pain (CBP, back pain >10 yr) patients to control (CON) subjects. ⋯ Furthermore, in SBP patients the strength of HG-mPFC reflected variations in back pain over the year. These relationships were replicated when examined in a different task performed by SBP patients (rating fluctuations of back pain), indicating that functional connectivity of the hippocampus changes robustly in subacute pain and the nature of these changes depends on whether or not patients recover from SBP. The observed reorganization of processing within the hippocampus and between the hippocampus and the cortex seems to contribute to the transition from subacute to chronic pain and may also underlie learning and emotional abnormalities associated with chronic pain.
