Pain and its disruptive impact on daily life are common reasons that patients seek primary medical care. Pain contributes strongly to psychopathology, and pain and depressive symptoms are often comorbid in primary care patients. Not all those who experience pain develop depression, suggesting that the presence of individual-level characteristics, such as positive and negative affect, that may ameliorate or exacerbate this association. ⋯ The association between pain and depressive symptoms is attenuated when greater levels of positive affects are present. Therapeutic bolstering of positive affect in primary care patients experiencing pain may reduce the risk for depressive symptoms.

To understand facilitators and barriers to participation in a peer support intervention for self-management of chronic pain. ⋯ Awareness of facilitators and barriers to participation in a peer-supported self-management program for chronic pain, as well as strategies to capitalize on facilitators and mitigate barriers, are essential for further study and ultimate clinical implementation of such a program.

There is no well-defined predictor of satisfactory pain relief after celiac plexus block (CPB) at the early stage of treatment. This study evaluated whether measurement of the electrocardiographic R-wave and the arrival time of the pulses at the toe pulse transit time (E-T PTT) can be an early predictor of pain response and success of CPB in patients with chronic intractable visceral pain. ⋯ Prolongation of E-T PTT at 5 minutes after CPB correlates closely with a significant analgesic effect.

Review Meta Analysis
Psychological Factors and Conditioned Pain Modulation: A Meta-Analysis.
Conditioned pain modulation (CPM) responses may be affected by psychological factors such as anxiety, depression, and pain catastrophizing; however, most studies on CPM do not address these relations as their primary outcome. The aim of this meta-analysis was to analyze the findings regarding the associations between CPM responses and psychological factors in both pain-free individuals and pain patients. ⋯ Certain psychological factors seem to be associated with modality-specific CPM responses in healthy individuals. This potentially supports the notion that CPM paradigms evoked by different stimulation modalities represent different underlying mechanisms.
