Comparative StudyHemodynamic parameters obtained by transthoracic echocardiography and right heart catheterization: a comparative study in patients with pulmonary hypertension.
Hemodynamic evaluation is crucial for the management of patients with pulmonary hypertention. Clinicians often prefer a rapid and non-invasive method. This study aimed to examine the feasibility of transthoracic echocardiography for the measurements of hemodynamic parameters in patients with pulmonary hypertension. ⋯ The non-invasive measurements by PASP, PADP, and CO in patients with pulmonary hypertension correlate well with the invasive determinations. Transthoracic echocardiography (TTE) was inappropriate for estimating PCWP and PAMP.

Sixty-two severe and critical patients with 2009 influenza A (H1N1) in Shanghai, China.
Pandemic influenza A (H1N1) emerged rapidly in China in May 2009. Preliminary comparisons with seasonal influenza suggest that pandemic 2009 influenza A (H1N1) disproportionately affects younger ages and causes generally mild disease. To characterize disease progress, comorbidities, and treatment outcomes among consecutive severe and critically ill patients in a hospital served as a reference center for the care of patients with H1N1 in Shanghai, China. ⋯ Severe illness from 2009 influenza A (H1N1) infection in Shanghai occurred among young individuals. Critical cases were associated with severe hypoxemia, multisystem organ failure, and a requirement for mechanical ventilation. Most patients had a good prognosis.
