Myocarditis in COVID-19 presenting with cardiogenic shock: a case series.

Background: SARS-CoV2, also known as COVID-19, is a specific strain of coronavirus that is responsible for an ongoing global pandemic. COVID-19 primarily targets the respiratory system via droplet transmission, causing symptoms similar to influenza, including fever, cough, and shortness of breath. It is now known to impact other organ systems, causing significant cardiovascular and gastrointestinal illness, among others.

The impact of deployment on COPD in active duty military personnel.

Purpose: To identify trends in chronic obstructive pulmonary disease (COPD) diagnoses among active duty U.S. military personnel based on deployment history and whether International Classification of Disease, 9th edition (ICD-9) coding meet criteria for the diagnosis of COPD.

Correlation of airway hyper-responsiveness with obstructive spirometric indices and FEV(1) > 90% of predicted.

Background: Current published guidelines on spirometry interpretation suggest an elevated FVC and FEV(1) > 100% of predicted with an obstructive ratio may represent a physiological variant. There is minimal evidence whether this finding can be indicative of symptomatic airways obstruction.

Methods: Pulmonary function testing databases for a 4-year period were retrospectively reviewed.
