Ten Chronic Overlapping Pain Conditions (COPCs) are currently recognized by the National Institutes of Health Pain Consortium (eg, irritable bowel syndrome, chronic migraine headache, and chronic low back pain). These conditions affect millions of Americans; however, assessing these conditions, their co-occurrence, and their relationship to treatment has proven challenging due to time constraints and a lack of standardized measures. We present a Chronic Overlapping Pain Condition-Screener (COPC-S) that is logic-driven, efficient, and freely available in electronic format to nonprofit entities. ⋯ PERSPECTIVE: Assessing COPCs remains a challenge for researchers and clinicians. The COPC-S is an efficient and logic-driven electronic tool that allows for the rapid screening assessment of 10 COPCs. The instrument may have utility in research and clinical settings.

Persistent Genital Arousal Disorder/Genito-Pelvic Dysesthesia (PGAD/GPD), which affects up to 4.3% of individuals, is a distressing and poorly understood condition characterized by persistent, unwanted, and often painful sensations of genito-pelvic arousal (eg, throbbing) in the absence of sexual desire. PGAD/GPD is associated with significant negative impacts on psychosocial well-being and daily functioning. Recent research has indicated that PGAD/GPD shares many similarities with other forms of chronic genito-pelvic pain. ⋯ Interventions targeting fear-avoidance factors may help to reduce PGAD/GPD symptom intensity, distress, and increase psychological well-being and daily functioning. PERSPECTIVE: This article provides support for the applicability of the fear-avoidance model of chronic pain to Persistent Genital Arousal Disorder/Genito-Pelvic Dysesthesia (PGAD/GPD). These results suggest that interventions targeting fear-avoidance cognitions and behaviors (catastrophizing, fear, avoidance, hypervigilance) may help to reduce PGAD/GPD symptom intensity and improve psychological well-being and daily functioning.

Most reports agree that aging negatively impacts pain processing and that the prevalence of chronic pain increases significantly with age. To improve current therapies, it is critical that aged animals be included in preclinical studies. Here we compared sensitivities to pain and itch-provoking stimuli in naïve and injured young and aged mice. ⋯ That observation is consistent with our finding of contralateral hypersensitivity after nerve injury in the aged but not the young mice. We conclude that aging has opposite effects on baseline versus postinjury pain and itch processing. PERSPECTIVE: Aged male and female mice (22-24 months) are less sensitive to mechanical, thermal (heat), and itch-provoking stimuli than are younger mice (6 months).

Two common elements in patient care are reoccurring painful events (eg, blood draws) and verbal suggestions from others for lessened pain. Research shows that verbal suggestions for lower pain can decrease subsequent pain perception from novel noxious stimuli, but it is less clear how these suggestions and prior painful experiences combine to influence the perception of a reoccurring painful event. The presented experiment tested the hypothesis that the order of these 2 factors influence pain perception for a reoccurring painful event. ⋯ Given many pain events within medical contexts are, or become, familiar to patients, further researching the timing at which patients receive verbal suggestions for lower pain can inform practices to optimize the therapeutic, pain-reducing potential of such suggestions. PERSPECTIVE: Providing suggestions that a familiar pain event (ie, the second of 2) will be less painful than a prior event can reduce perceived pain for the familiar event depending on when it is presented. These findings can inform practices to optimize the therapeutic potential of verbal suggestions for reduced pain.

We previously conducted an exploration of the trustworthiness of a group of clinical trials of cognitive-behavioral therapy and exercise in spinal pain. We identified multiple concerns in 8 trials, judging them untrustworthy. In this study, we systematically explored the impact of these trials ("index trials") on results, conclusions, and recommendations of systematic reviews and clinical practice guidelines (CPGs). ⋯ PERSPECTIVE: We found that a group of trials of CBT for spinal pain with concerns relating to their trustworthiness has had substantial impacts on the analyses and conclusions of systematic reviews and clinical practice guidelines. This highlights the need for a greater focus on the trustworthiness of studies in evidence appraisal. PRE-REGISTRATION: Our protocol was preregistered on the Open Science Framework: https://osf.io/m92ax/.
