Background: Sessile serrated adenomas/polyps (SSA/P) are an under-recognized disease with a unique malignant pathway. Improved endoscopic recognition and pathological interpretation is needed.

Aims: To determine whether an educational intervention that improved adenoma detection rate (ADR) could improve SSA/P detection rate after reclassification of previously termed "hyperplastic" polyps.

Objective: To determine the incidence of ventricular tachycardia and ventricular fibrillation in patients with prolonged corrected QT interval (QTc) who received levofloxacin through retrospective chart review at a tertiary care teaching hospital in the United States.

Patients And Methods: We selected 1004 consecutive hospitalized patients with prolonged QTc (>450 ms) between October 9, 2009 and June 12, 2012 at our institution. Levofloxacin was administered orally and/or intravenously and adjusted to renal function in the inpatient setting.

Background/aim: Nucleic acid metabolism is biochemically compartmentalized to the nucleus. Thus, it is necessary to define the proteome of the various macromolecular structures within this organelle.

Materials And Methods: We isolated the nuclear matrix (NM) fraction from rat liver by sequential centrifugation steps at 13,000 rpm, staggered between endogenous nuclease treatment for 2 h at 37°C, followed by high-salt (H.

Background: Patients undergoing high-definition white-light colonoscopy by a high adenoma detector may have a lower risk of interval adenoma detection on follow-up colonoscopy and may require less frequent follow-up but may paradoxically be assigned to more frequent surveillance when more adenomas are detected.

Aims: To evaluate whether high-definition white-light colonoscopy (vs. standard-definition white-light colonoscopy) and endoscopist adenoma detection rate (ADR) at index colonoscopy are associated with increased likelihood of adenomas at follow-up.

Background: Outcomes on colon endoscopic mucosal resection in the very elderly patient population are unknown.

Aims: Aims of this study were to evaluate the outcomes and safety of colon endoscopic mucosal resection in this target population.

Methods: Observational, retrospective study of patients ≥ 80 years of age that underwent colon endoscopic mucosal resection ≥ 2 cm.
