Methemoglobinemia in the Era of COVID-19: A Potential Confounder of Glycemic Control.

Glycated hemoglobin A (HbA) is frequently used as a measure of glycemic control but can be inaccurate in certain clinical scenarios leading to poor estimates of insulin requirements. We present the case of a 76-year-old man with diabetes and COVID infection. HbA was measured at 5.

International cost-effectiveness analysis evaluating endoscopic screening for gastric cancer for populations with low and high risk.

Background: Gastric cancer remains one of the 3 most common causes of cancer death worldwide. Understanding the health and economic factors that affect screening cost-effectiveness in different countries will help address when and where it makes most sense to screen for gastric cancer.

Methods: We performed a cost-effectiveness analysis using a Markov model to compare screening and surveillance strategies for gastric cancer in Brazil, France, Japan, Nigeria, and the United States.

Disease Course and Outcomes of COVID-19 Among Hospitalized Patients With Gastrointestinal Manifestations.

Background & Aims: Our understanding of outcomes and disease time course of COVID-19 in patients with gastrointestinal (GI) symptoms remains limited. In this study we characterize the disease course and severity of COVID-19 among hospitalized patients with gastrointestinal manifestations in a large, diverse cohort from the Unites States.

Methods: This retrospective study evaluated hospitalized individuals with COVID-19 between March 11 and April 28, 2020 at two affiliated hospitals in New York City.

Evolving Approaches to Tissue Expander Design and Application.

Prosthetic reconstruction utilizing a 2-stage saline tissue expander-to-implant procedure is the most common technique for breast reconstruction in the United States. For nearly the past 50 years, 2-stage breast reconstruction using saline tissue expanders has been the standard of care. However, in December 2016, a carbon dioxide-filled, remote-controlled tissue expander received U.

Long-term failure of Amplatzer plugs in the treatment of aortic pathology.

We present two cases of Amplatzer® device deployment that exhibited long-term failure necessitating surgical correction. The first case illustrates recanalization of a ruptured Valsalva aneurysm with worsening aortic insufficiency after percutaneous repair with the Amplatzer Vascular Plugs and Amplatzer duct occluder, while the second case illustrates recanalization after deployment of the Amplatzer septal occluder in a patient with a pseudoaneursym in a bovine aorta after type I aortic dissection repair. These two cases illustrate the potential long-term complications and limitations in durability with these devices.
