Logistical Considerations and Clinical Outcomes Associated With Converting Operating Rooms Into an Intensive Care Unit During the Coronavirus Disease 2019 Pandemic in a New York City Hospital.

Background: Coronavirus disease 2019 (COVID-19) emerged as a public health crisis that disrupted normal patterns of health care in the New York City metropolitan area. In preparation for a large influx of critically ill patients, operating rooms (ORs) at NewYork-Presbyterian/Columbia University Irving Medical Center (NYP-Columbia) were converted into a novel intensive care unit (ICU) area, the operating room intensive care unit (ORICU).

Methods: Twenty-three ORs were converted into an 82-bed ORICU.

Emergent Transcatheter Aortic Valve Replacement for Aortic Insufficiency.

There are few case reports in the literature of transcatheter aortic valve replacement used as emergent therapy for aortic insufficiency. We present a case in which transcatheter aortic valve replacement was implemented successfully as a salvage therapy in a hemodynamically unstable patient having aortic insufficiency as a result of a torn bioprosthetic leaflet during an unrelated abdominal operation. The successful use of this technique in a noncardiac operating room allowed the patient to be placed on extracorporeal support and ultimately to be discharged home.

Monitored Anesthesia Care for the Acute Ischemic Stroke Patient with End-stage Pulmonary Disease.

The majority of patients who suffer acute ischemic stroke (AIS) from large vessel occlusion are at a significant risk for disability or death. Because patients on veno-arterial extracorporeal membrane oxygenation (VA ECMO) are therapeutically anticoagulated, intravenous recombinant tissue plasminogen activator is contraindicated. For AIS management, these patients must undergo emergent intra-arterial therapy.

The scientific rationale and development of an optimized dentifrice for the treatment of dentin hypersensitivity.

Purpose: To describe the development of a new dentin hypersensitivity treatment, Colgate Sensitive Maximum Strength dentifrice, containing 5% potassium nitrate as the anti-hypersensitivity active agent. The objective was to develop a home-use hypersensitivity dentifrice that would be superior to the market leader, improving on what is available, which also contains 5% potassium nitrate as the anti-hypersensitivity active agent.

Methods: In vivo (clinicals, taste evaluation and rat caries), in vitro (potassium flux) and analytical (rheology, dispensed volume, scanning electron microscopy, electron scanning chemical analysis and radioactive dentin abrasion) methods were performed.
