Abstract
OBJECTIVE Roux-en-Y gastric bypass surgery (RYGB) is among the most effective therapies for obesity and type 2 diabetes, and intestinal adaptation is a proposed mechanism for these effects. It was hypothesized that intestinal adaptation precedes and relates to metabolic improvement in humans after RYGB. METHODS This was a prospective, longitudinal, first-in-human study of gene expression (GE) in the "Roux limb" (RL) collected surgically/endoscopically from 19 patients with and without diabetes. GE was determined by microarray across six postoperative months, including at an early postoperative (1 month ± 15 days) time point. RESULTS RL GE demonstrated tissue remodeling and metabolic reprogramming, including increased glucose and amino acid use. RL GE signatures were established early, before maximal clinical response, and persisted. Distinct GE fingerprints predicted concurrent and future improvements in HbA1c and in weight. Human RL exhibited GE changes characterized by anabolic growth and shift in metabolic substrate use. Paradoxically, anabolic growth in RL appeared to contribute to the catabolic state elicited by RYGB. CONCLUSIONS These data support a role for a direct effect of intestinal energy metabolism to contribute to the beneficial clinical effects of RYGB, suggesting that related pathways might be potential targets of therapeutic interest for patients with obesity with or without type 2 diabetes.

Jotwani ML, Wu Z, Lunde CE, Sieberg CB. The missing mechanistic link: Improving behavioral treatment efficacy for pediatric chronic pain. FRONTIERS IN PAIN RESEARCH (LAUSANNE, SWITZERLAND) 2022; 3:1022699. [PMID: 36313218 PMCID: PMC9614027 DOI: 10.3389/fpain.2022.1022699] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 08/18/2022] [Accepted: 09/26/2022] [Indexed: 11/07/2022]
Abstract
Pediatric chronic pain is a significant global issue, with biopsychosocial factors contributing to the complexity of the condition. Studies have explored behavioral treatments for pediatric chronic pain, but these treatments have mixed efficacy for improving functional and psychological outcomes. Furthermore, the literature lacks an understanding of the biobehavioral mechanisms contributing to pediatric chronic pain treatment response. In this mini review, we focus on how neuroimaging has been used to identify biobehavioral mechanisms of different conditions and how this modality can be used in mechanistic clinical trials to identify markers of treatment response for pediatric chronic pain. We propose that mechanistic clinical trials, utilizing neuroimaging, are warranted to investigate how to optimize the efficacy of behavioral treatments for pediatric chronic pain patients across pain types and ages.
