INTRODUCTION: The purpose of this study was to compare the occurrence of microcracks in teeth prepared with different retreatment systems using microcomputed tomography (micro-CT). METHODS: Forty-two freshly extracted mandibular premolar teeth were used. The root canals were instrumented with stainless steel K-files to an apical size of 35/.02 using the balanced-force technique and were obturated using the passive compaction technique. The specimens were divided into 3 experimental groups according to retreatment system used (n = 14): ProTaper Universal retreatment (PTUR), Mtwo retreatment (MTR), or D-RaCe retreatment (D-RC) systems...

BACKGROUND: There has been indisputable growth in adoption of electronic medical record (EMR) systems in the recent years. However, physicians' progress in using these systems has stagnated when measured with maturity scales. While this so-called ceiling effect has been observed and its consequences described in previous studies, there is a paucity of research on the elements that could explain such an outcome. We first suggest that in the context of EMR systems we are in presence of a "tiered ceiling effect" and then we show why such phenomenon occurs...

Currently, several endoscopic resection (ER) methods for colorectal tumors are available, including polypectomy, conventional endoscopic mucosal resection (EMR), endoscopic submucosal dissection (ESD), and modified ER. In the present review, we mainly focus on the current status of ER for colorectal tumors as well as the report from the Endoscopic Forum Japan (EFJ) 2016, which was held in Tokyo in August 2016. The proposed ER methods for colorectal tumors larger than 10 mm in diameter are as follows. (i) Pedunculated-type tumor is an indication for polypectomy, regardless of size...

BACKGROUND AND AIM: Endoscopic submucosal dissection (ESD), which provides a higher en bloc resection rate than conventional endoscopic mucosal resection (EMR), is considered to be a useful treatment option for large colorectal tumors. However, colorectal ESD is not widely used because of its technical difficulty, risk of complications and time required. To overcome these drawbacks, a simpler modified technique, ESD with snaring (hybrid ESD), has been developed. The aim of the present study was to retrospectively compare the safety and efficacy of hybrid ESD and conventional ESD for colorectal tumors...

PURPOSE: Perioperative antibiotics decrease rates of surgical-site infections. Numerous interventions have improved administration of the first antibiotic dose; however, failures in the administration of subsequent doses frequently occur. We hypothesized that modifications to the electronic medical record (EMR) would improve the administration of the second antibiotic dose and that such improvements would be sustained over time. METHODS: This historical cohort before-and-after study of multipronged alerts in the EMR analyzed 1,348 operations on adult patients...

REVIEW
Samuel Han, Sachin Wani
Barrett's esophagus (BE) is a well-established premalignant condition for esophageal adenocarcinoma (EAC); a cancer that is associated with a poor 5-year survival rate. Several strategies have been explored in the context of reducing the burden of EAC. Endoscopic eradication therapy (EET) is considered the standard of care for the management of patients with BE with dysplasia and early neoplasia; a practice that has been endorsed by all gastroenterology societal guidelines. The effectiveness of EET has been demonstrated in multiple studies and contemporary management includes a combination of endoscopic mucosal resection (EMR) of all visible lesions followed by eradication of the remaining BE using ablative techniques of which radiofrequency ablation (RFA) has the best evidence supporting effectiveness and safety...

Low-socioeconomic status (SES) households have little income or wealth to buffer against the negative impacts of an adverse health event (health shock) among adult household members. However, these households may employ a variety of other coping strategies such as receiving help from family, friends, and social services. Administrative data from a non-profit food distribution center, electronic medical record (EMR) data from a safety-net healthcare system, and publicly available residential appraisal data were linked to provide insight into these coping strategies...
