Multicenter Study Comparative Study Clinical Trial
Computed Tomography Colonography vs Colonoscopy for Colorectal Cancer Surveillance After Surgery.
Recommendations for surveillance after curative surgery for colorectal cancer (CRC) include a 1-year post-resection abdominal-pelvic computed tomography (CT) scan and optical colonoscopy (OC). CT colonography (CTC), when used in CRC screening, effectively identifies colorectal polyps ≥10 mm and cancers. We performed a prospective study to determine whether CTC, concurrent with CT, could substitute for OC in CRC surveillance. ⋯ In a CRC surveillance population 1 year following resection, CTC was inferior to OC for detecting patients with polyps ≥6 mm. Clinical Trials.gov Registration Number: NCT02143115.

Randomized Controlled Trial Multicenter Study
Factors Associated With Response to Teduglutide in Patients With Short-Bowel Syndrome and Intestinal Failure.
Clinical studies showed teduglutide to increase urine production and reduce need for parenteral support volume in patients with short bowel syndrome (SBS) with intestinal failure, increasing intestinal wet weight absorption and reducing diarrhea. However, the effects of teduglutide on parenteral support vary among patients. We performed a post hoc analysis of a phase III placebo-controlled study to identify characteristics of patients in whom teduglutide has the largest effects on parenteral support volume response. ⋯ In a post hoc analysis of data from a phase III study of the effects of teduglutide on patients with SBS, we associated reduced parenteral support volume with baseline parenteral support volume, bowel anatomy, and SBS features. These findings may inform initial parenteral support volume adjustments and management of these severely disabled patients.

Preclinical studies have shown aspirin to have anticancer properties and epidemiologic studies have associated aspirin use with longer survival times of patients with cancer. We studied 2 large cohorts to determine the association between aspirin use and cancer-specific mortality in patients with esophageal or gastric cancer. ⋯ In analyses of 2 large independent cohorts in the United Kingdom, low-dose aspirin usage was not associated with increased survival of patients diagnosed with esophageal or gastric cancer.

Central neuromodulators (antidepressants, antipsychotics, and other central nervous system-targeted medications) are increasingly used for treatment of functional gastrointestinal disorders (FGIDs), now recognized as disorders of gut-brain interaction. However, the available evidence and guidance for the use of central neuromodulators in these conditions is scanty and incomplete. In this Rome Foundation Working Team report, a multidisciplinary team summarized available research evidence and clinical experience to provide guidance and treatment recommendations. ⋯ Based on systematic and selectively focused review and the consensus of a multidisciplinary panel, we have provided summary information and guidelines for the use of central neuromodulators in the treatment of chronic gastrointestinal symptoms and FGIDs. Further studies are needed to confirm and refine these recommendations.
