Objectives: Endoscopic mucosal resection (EMR) is an established technique for the management of Barrett's esophagus (BE). Although EMR is generally perceived to be a relatively safe procedure, the published data regarding EMR-related complications are variable and the expertise of those performing EMR is often not disclosed. Our aim was to determine the complication rates in a large cohort of patients who underwent EMR at a specialized BE unit.
Methods: A prospectively maintained database was reviewed for patients with BE who underwent EMR from January 1995 to August 2008. EMR was performed in patients with neoplastic appearing lesions. Bleeding, stricture, and perforation related to EMR were reviewed as the main outcome measurements.
Results: In all, 681 patients (83% male; mean age 70 years old) underwent a total of 1,388 endoscopic procedures and 2,513 EMRs. Median length of BE was 3.0 cm (interquartile range (IQR) 1-7). A single experienced endoscopist performed 99% of the EMR procedures. EMR was performed using commercially available EMR kits in 95% (77% cap-snare and 18% band-snare) and a variceal band ligation device in 5% of cases. No EMR-related perforations occurred during the study period. The rate of post-EMR bleeding was 1.2% (8 patients). Seven patients were successfully treated endoscopically and one needed surgery. The rate for symptomatic strictures after EMR was 1.0% (7 cases), and all of the cases did not involve intervening ablation therapies. All strictures were successfully treated with endoscopic dilation.
Conclusions: This is the largest series reported to date on EMR in BE. In this large retrospective study, EMR for BE was associated with a low rate of complications for selected patients when performed by experienced hands.

Stabilizing large easy-axis type magnetic anisotropy in molecular complexes is a challenging task, yet it is crucial for the development of information storage devices and applications in molecular spintronics. Achieving this requires a deep understanding of electronic structure and the relationships between structure and properties to develop magneto-structural correlations that are currently unexplored in the literature. Herein, a series of five-coordinate distorted square pyramidal Co complexes [Co(L)(X)].

Previous work identified a sub-group of trauma patients at risk for bacteremia who presented with signs of infection, including fever. A majority were older adult falls who had early onset bacteremia. Fever in the trauma bay is associated with a greater risk of adverse outcomes and identifies patients who might benefit from early initiation of interventions for sepsis.

Background: Delivering adequate quality care remains a challenge in many low-and middle-income countries (LMICs), especially for people living with type 1 diabetes (T1D), requiring a complex treatment regimen. Digital health solutions, including electronic medical record (EMR) systems, have shown potential to improve delivery and quality of care but still require a successful implementation.
Objective: To analyze the adoption of a newly implemented EMR system in Rwanda from the perspectives of individuals with T1D, health care providers, and experts.
