SARS-CoV-2 pandemic in New York metropolitan area: the view from a major urgent care provider.

Purpose: Tracking severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) testing and positivity trends is crucial for understanding the trajectory of the pandemic. We describe demographic and clinical characteristics, testing, and positivity rates for SARS-CoV-2 among 2.8 million patients evaluated at an urgent care provider.

The emergence, surge and subsequent wave of the SARS-CoV-2 pandemic in New York metropolitan area: The view from a major region-wide urgent care provider.

Background: Describing SARS-CoV-2 testing and positivity trends among urgent care users is crucial for understanding the trajectory of the pandemic.

Objective: To describe demographic and clinical characteristics, positivity rates, and repeat testing patterns among patients tested for SARS-CoV-2 at CityMD, an urgent care provider in the New York City metropolitan area.

Design: Retrospective study of all persons testing for SARS-CoV-2 between March 1, 2020 and January 8, 2021 at 115 CityMD locations in the New York metropolitan area.

EXHANCE-3: a cohort study of the exhalation delivery system with fluticasone for chronic sinusitis with or without nasal polyps.

Background: Inhaled nasal corticosteroid sprays (INS) are often inadequate to treat chronic rhinosinusitis (CRS). The exhalation delivery system with fluticasone (EDS-FLU; XHANCE®) may improve outcomes in CRS by increasing medication delivery to target superior/posterior anatomic sites. This study assessed safety and efficacy of EDS-FLU in a large population with moderate-to-severe CRS with or without nasal polyps (CRSwNP, CRSsNP).

Coordination of multidisciplinary resources for vaccination of egg-allergic individuals during an H1N1 (novel) influenza pandemic.

Egg allergy is a contraindication for influenza vaccination because of the presence of trace egg protein. Although recent reports suggest that egg-allergic individuals can be safely immunized with seasonal influenza vaccine, the safety of H1N1 influenza vaccine in this context has not previously been reported. This study was designed to investigate how to safely immunize high-risk populations during the H1N1 influenza pandemic for whom the vaccine would be contraindicated.

Lymphocyte transformation induced by autologous cells. XVII. Lower autologous mixed lymphocyte reaction in subjects with a history of hayfever.

The autologous mixed lymphocyte reaction (AMLR) is impaired in patients with a number of diseases associated with abnormal immunoregulation. Since allergic disorders are also associated with abnormal immunoregulation, we assessed the AMLR in individuals with a history of ragweed hayfever. Lymphocytes from allergic subjects had a lower AMLR than nonallergic controls by rank order analysis.
