Previous studies have reported sex differences in patients with irritable bowel syndrome and inflammatory bowel disease, including differences in visceral pain perception. Despite this, sex differences in behavioral manifestations of visceral pain and underlying pathology of the gastrointestinal tract have been largely understudied in preclinical research. In this study, we evaluated potential sex differences in spontaneous nociceptive responses, referred abdominal hypersensitivity, disease progression, and bowel pathology in mouse models of acute and persistent colon inflammation. ⋯ During persistent colon inflammation, males exhibit worse disease progression than females, which is manifested as worse physical appearance and higher weight loss. However, no measurable sex differences were observed in persistent inflammation-induced bowel pathology, stool consistency, or fecal blood. Overall, our findings demonstrate sex differences in pain-related behaviors and disease progression in the context of acute and persistent colon inflammation, highlighting the importance of considering sex as a biological variable in future mechanistic studies of visceral pain as well as in the development of diagnostics and therapeutic options for chronic gastrointestinal diseases.

No strong and consistent variables to predict outcome after pain rehabilitation have been reported in patients with chronic musculoskeletal pain. The aim of the present study was to clarify if baseline variables could predict successful outcome after a unique, individualized, physiotherapist-led rehabilitation of nine sessions. ⋯ Of 17 potentially predictive baseline variables, mild pain ratings, short pain duration, and localized baseline pain were statistically significantly associated with improvements after individual, physiotherapist-led rehabilitation for patients with chronic musculoskeletal pain. This suggests that this type of rehabilitation probably should be offered early in the pain process. Reporting anxiety/depression or severe pain at the baseline did not hinder the improvements of overall health.

Pain management is a major medical issue. However, current medical education in Japan is inadequate with regard to training students to properly assess patients with acute and chronic pain and plan their treatment. Therefore, starting in 2019, Hyogo Medical University established a multidisciplinary educational system to better train medical students to provide pain care. ⋯ The test results were compared in terms of the percentage of correct answers and the total score for each question using McNemar's chi-square test and paired t-tests, respectively. The results showed a significant improvement in the mean of the total score, confirming the improvement in medical students' knowledge (6.43 vs. 7.35 points; p < 0.001). Based on the results, overall, pain education at the university has had positive outcomes and will therefore be continued in the future.
