Usage Information
Abstract
Bone formation in soft tissues, known as heterotopic ossification (HO), can occur as a complication of trauma or burn injury and can cause pain and functional limitations in the affected site. HO remains an unmet clinical challenge due to a general lack of specific medical therapies. In this issue of the JCI, a study by Moye et al. identified obesity as a risk factor for HO and further found that the association with obesity was driven not by caloric surplus, but instead by dietary omega-6 lipids, which are characteristically elevated in the Western diet. These omega-6 lipids accumulated directly at the incipient HO site, where they served as substrates for prostaglandin E2 (PGE2), fueling aberrant osteoblast differentiation. Overall, this work provides compelling support for dietary intervention or pharmacologic therapy directed at downstream PGE2 signaling as approaches to reduce HO in at-risk patients.

Usage information is collected from two different sources: this site (JCI) and Pubmed Central (PMC). JCI information (compiled daily) shows human readership based on methods we employ to screen out robotic usage. PMC information (aggregated monthly) is also similarly screened of robotic usage.
Various methods are used to distinguish robotic usage. For example, Google automatically scans articles to add to its search index and identifies itself as robotic; other services might not clearly identify themselves as robotic, or they are new or unknown as robotic. Because this activity can be misinterpreted as human readership, data may be re-processed periodically to reflect an improved understanding of robotic activity. Because of these factors, readers should consider usage information illustrative but subject to change.
