Do diabetes-related foot ulcer wound fluid measures have clinical utility as biomarkers for healing? A systematic review.

Objective: This study aimed to identify potential biomarkers reported in wound fluid of diabetes-related foot ulcers (DRFUs), and their ability to reflect current and prospective wound healing.

Method: A systematic search was executed following the PRISMA methodology across five chosen databases: MEDLINE, Embase, Scopus, Cochrane Clinical Trials and Cochrane Systematic Reviews. Using keywords and phrases, it yielded 5022 results.

Assessment of the anti-hyperalgesic efficacy of J-2156, relative to clinically available analgesic/adjuvant agents in a rat model of mild to moderate chronic mechanical low back pain (LBP).

Chronic mechanical low back pain (cLBP) is a leading cause of disability and a major socio-economic burden internationally. The lifetime prevalence of non-specific LBP is approximately 84%, with the prevalence of cLBP at about 23%. Clinically available analgesic/adjuvant medications often provide inadequate pain relief in patients experiencing cLBP.

Comparison of Burrowing and Stimuli-Evoked Pain Behaviors as End-Points in Rat Models of Inflammatory Pain and Peripheral Neuropathic Pain.

Establishment and validation of ethologically-relevant, non-evoked behavioral end-points as surrogate measures of spontaneous pain in rodent pain models has been proposed as a means to improve preclinical to clinical research translation in the pain field. Here, we compared the utility of burrowing behavior with hypersensitivity to applied mechanical stimuli for pain assessment in rat models of chronic inflammatory and peripheral neuropathic pain. Briefly, groups of male Sprague-Dawley rats were habituated to the burrowing environment and trained over a 5-day period.
