Characterization of Emergency Department Quality Assurance Cases Seen Within a Midwestern United States Health System.

Background: Hospital quality-assurance (QA) processes, including peer-review committees, seek to identify high-risk areas.

Purpose: To characterize emergency department (ED) cases sent for QA review.

Methods: A retrospective observational study was conducted of ED cases sent to a QA committee from November 2018 through July 2022 at three midwestern US hospitals.

Evaluation of computed tomography perfusion and angiogram use in stroke evaluation for thrombectomy at a community emergency department setting.

Purpose: Evaluate concordance of provider practices with clinical guidelines for thrombectomy screening in an emergency department (ED) via computed tomography perfusion and angiogram (CT-P/A).

Methods: A retrospective observational study was conducted for patients 18 years or older who received a CT-P/A of the head and neck in a US Midwestern ED between September 2019 through June 2021. Healthcare system records reviewed for patient information, CT-P/A findings, and treatment decisions.

Ethical issues and obligations with undocumented immigrants relying on emergency departments for dialysis.

Undocumented immigrants with end-stage renal disease in the United States are uniquely disadvantaged in their ability to access dialysis. This article examines the unique circumstances of the medical condition and healthcare system, including the relevant legal and regulatory influences that largely relegate undocumented immigrants to relying on emergency-only dialysis through a hospital's Emergency Medical Treatment and Labor Act obligations. We explore the ethical implications of this current state, emphasizing the adverse effects on patients and staff alike.

Characteristics and retention of emergency department patients who left without being seen (LWBS).

A retrospective observational study was conducted for patients 18 years or older presenting to a Midwestern emergency department (ED) in the United States during February 2019-January 2020 to characterize associated subsequent care utilization in patients who left the ED without being seen. Patients were classified as left without being seen (LWBS) based on documented ED disposition. The healthcare system's records were reviewed for any associated utilizations within 3 weeks following the initial ED encounter.

Ethical issues in the access to emergency care for undocumented immigrants.

Patients who are undocumented immigrants (UIs) frequently present to emergency departments in the United States, especially in communities with large immigrant populations. Emergency physicians confront important ethical issues when providing care for these patients. This article examines those ethical issues and recommends best practices in emergency care for UIs.

Iejimalides A and B inhibit lysosomal vacuolar H+-ATPase (V-ATPase) activity and induce S-phase arrest and apoptosis in MCF-7 cells.

Iejimalides are novel macrolides that are cytostatic or cytotoxic against a wide range of cancer cells at low nanomolar concentrations. A recent study by our laboratory characterized the expression of genes and proteins that determine the downstream effects of iejimalide B. However, little is known about the cellular target(s) of iejimalide or downstream signaling that lead to cell-cycle arrest and/or apoptosis.
