Seasonality and pediatric inflammatory bowel disease.
The researchers sought to determine whether disease activity in pediatric-onset inflammatory bowel disease (IBD) is associated with a seasonal pattern. Studying 1325 patients with Crohn disease and 587 patients with ulcerative colitis, their findings do not support any strong associations between season of the year and disease activity in pediatric IBD.

Spatial and temporal stability of paneth cell phenotypes in Crohn's disease: implications for prognostic cellular biomarker development.
The researchers sought to develop Paneth cell phenotype as a prognostic biomarker in Crohn’s disease by additional characterization building on their earlier research. Specifically, they examined the effects of disease activity, phenotype duration, and the minimal crypt number that would allow for accurate Paneth cell phenotyping. They demonstrated that Paneth cell phenotypes are not affected either by disease activity or by exposure to therapeutic agents.

Harnessing claims to improve detection of surgical site infections following hysterectomy and colorectal surgery.
The researchers conducted retrospective cohort studies at 2 academic medical centers, extending analyses of patients undergoing hysterectomy or colorectal surgery. They concluded that claims-enhanced surveillance can help to identify surgical site infections (SSIs) missed by routine surveillance, identifying nearly twice as many SSIs following hysterectomy and 4 times more SSIs following colorectal surgery.
