Inflammatory Bowel Disease (IBD) is a life-long disorder that often begins between the ages of 15 and 30. Anecdotal reports suggest cannabinoids may be an effective treatment. This study sought to determine whether home cage wheel running is an effective method to assess IBD, and whether Tetrahydrocannabinol (THC), the primary psychoactive compound in cannabis, can restore wheel running depressed by IBD. ⋯ In fact, administration of THC prolonged TNBS-induced depression of wheel running for over 5 days in adolescent and adult rats. These results show that home cage wheel running is depressed by TNBS-induced IBD, making it a useful tool to evaluate the behavioral consequences of IBD, and that administration of THC, instead of producing antinociception, exacerbates TNBS-induced IBD. PERSPECTIVE: This article advances research on inflammatory bowel disease in two important ways: 1) Home cage wheel running is a new and sensitive tool to assess the behavioral consequences of IBD in adolescent and adult rats; and 2) Administration of the cannabinoid THC exacerbates the negative behavioral effects of IBD.

Complex regional pain syndrome (CRPS) has never comprehensively been examined from a lived experience perspective. Patients generally have a poorer quality of life than people with other chronic pain conditions. This study aimed to understand the essence of living with CRPS. ⋯ Better health outcomes are experienced by patients when their personal situation and experiences are heard and understood by health care professionals. PERSPECTIVE: This article presents the lived experience of CRPS. This information and the model generated can help clinicians to better understand their patients and deliver appropriate patient-centered care.

While patient perceptions of burden to caregivers is of recognized clinical significance among people with chronic pain, perceived burden to treating physicians has not been studied. This study examined how people with chronic pain perceived levels of medical evidence (low vs high) and pain severity (4,6,8/10) to influence physician burden and how burden then mediated expected clinical judgments. 476 people with chronic pain read vignettes describing a hypothetical patient with varying levels of medical evidence and pain severity from the perspective of a treating physician, rated the burden that patient care would pose, and made a range of clinical judgments. The effect of pain severity on clinical judgments was expected to interact with medical evidence and be conditionally mediated by burden. ⋯ PERSPECTIVE: : People with chronic pain expect physicians to view the care of patients without supporting medical evidence as burdensome. Higher burden is associated with less symptom credibility, more psychosocial dysfunction, and less treatment benefit. Perceived physician burden appears to impact how patients approach treatment, with potentially adverse implications for clinical practice.
