As a result, weight loss is a common recommendation for pain management among those with higher body weight. Body weight is an appealing target because it is modifiable and evidence-based treatments to produce weight loss are well-established. In the last 2 decades, there has been a growing line of scientific work investigating the application of weight loss to individuals with chronic pain. This represents an important step to integrate the conceptualization of pain and body weight and there is preliminary work suggesting treatment effects are enhanced when weight loss treatment is combined with pain coping skills. However, weight loss outcomes are variable and difficult to sustain, and access to evidence-based treatment is limited. These concerns are set against the backdrop of growing public and academic concern about the weight-centric approach to health care that dominates western medicine. This is a timely moment to reconsider the conceptualization of weight and pain, and the role of weight loss in chronic pain treatment.

We used a longitudinal cohort study of middle-aged adults to investigate whether chronic pain is reciprocally associated with coverage by any insurance and type of insurance coverage over a 2-year period (2018 and 2020). Among 5,137 participants (median age of 57 years in 2018), 29% reported chronic pain in either year, while 9 to 10% were uninsured each year. Using multivariable cross-lagged logistic regression analysis, chronic pain in 2018 was not associated with having any insurance coverage in 2020, and lack of coverage in 2018 was not associated with chronic pain in 2020. In further analysis, we determined that public coverage, other (non-private) coverage, or no coverage in 2018 were associated with an increased risk of chronic pain in 2020; while chronic pain in 2018 increased the risk of coverage by public rather than private insurance 2 years later, as well as the risk of coverage by other (non-private) payors. The reciprocal association of non-private insurance coverage and chronic pain may be related to insufficient access to chronic pain treatment among publicly insured adults, or qualification for public insurance based on disability among adults with chronic pain.

Pain sensitivity was quantified by 8 distinct measures that were subdivided as static (ie, pressure pain thresholds, heat pain thresholds, fixed mechanical pain, and fixed cold pain) and dynamic pain sensitivity (ie, mechanical temporal summation, thermal ramp and hold, heat pain aftersensations, and conditioned pain modulation).

We examined the hypothesis that engaging mesenchymal stem cells (MSCs) would foster local neuroimmune interactions, leading to a potential reduction in postamputation pain. We utilized an ex vivo neuroma model from a phantom limb pain patient to uncover that the oligodeoxynucleotide IMT504 engaged human primary MSCs to promote an anti-inflammatory microenvironment. Reverse translation experiments recapitulated these effects. Thus, in an in vivo rat model, IMT504 exhibited strong efficacy in preventing autotomy (self-mutilation) behaviors. This effect was linked to a substantial accumulation of MSCs in the neuroma and associated dorsal root ganglia and the establishment of an anti-inflammatory phenotype in these compartments. Centrally, this intervention reduced glial reactivity in the dorsal horn spinal cord, demonstrating diminished nociceptive activity. Accordingly, the exogenous systemic administration of MSCs phenocopied the behavioral effects of IMT504.
