INTRODUCTION Acute cor pulmonale (ACP) and patent foramen ovale (PFO) remain common in patients under protective ventilation for acute respiratory distress syndrome (ARDS). We sought to describe the hemodynamic profile associated with either ACP or PFO, or both, during the early course of moderate-to-severe ARDS using echocardiography. METHODS In this 32-month prospective multicenter study, 1...

INTRODUCTION Idiopathic pulmonary fibrosis (IPF) is a severe disease with no known effective therapy. Patients with IPF may develop severe increase of pulmonary arterial pressure (PAP) on exercise, the mechanisms of which is not clearly identified. OBJECTIVES To determine whether oxygen may correct the increase of PAP developed during exercise in patients with IPF. PATIENTS AND METHODS We p...

Alkaline phosphatase (AP) is a bi-metalloenzyme with potential applications in biotechnology and bioremediation. The enzyme hydrolyses nonspecifically phosphate monoesters under alkaline conditions to yield inorganic phosphate. The AP isolated from the bacterium Sphingomonas sp. Strain BSAR-1 (SPAP) was shown to be particularly useful for the recovery of uranium from alkaline radioactive waste....

BACKGROUND Down's syndrome (DS) is a genetic anomaly, which undergoes increased morbidity and mortality when associated with congenital heart disease (CHD). The aims of the study were to determine the prevalence of CHD and pulmonary hypertension (PH) in DS. METHODS One hundred twenty-seven patients with DS living in Mexico City were evaluated by physical exam, electrocardiogram and echocardio...

BACKGROUND To date, Doppler echocardiography is the most widespread and well-recognized technique for the noninvasive evaluation of systolic pulmonary artery pressure (sPAP). However, recent studies have reported reservations about the relevance of Doppler echocardiography or the tool's reliability in the diagnosis and follow-up of patients with pulmonary hypertension (PH). Thus, the aim of thi...

Abstract Background Transthoracic Echocardiography (TTE) seems to be mistaken for the estimation of systolic Pulmonary Artery Pressure (sPAP) especially in patients with severe Tricuspid Regurgitation (TR). This study aimed determine reliability assessment sPAP by TTE this population. Methods is a monocentric analysis 236 consecutive concomitant Right Heart Catheterization (RHC) and performed a...

‎‎we exhibit an explicit construction for the second cohomology group‎ ‎$h^2(l‎, ‎a)$ for a lie ring $l$ and a trivial $l$-module $a$‎. ‎we show how the elements of $h^2(l‎, ‎a)$ correspond one-to-one to the‎ ‎equivalence classes of central extensions of $l$ by $a$‎, ‎where $a$‎ ‎now is considered as an abelian lie ring‎. ‎for a finite lie‎ ‎ring $l$ we also show that $h^2(l‎, ‎c^*) cong m(l)$‎...

BACKGROUND Pulmonary artery hypertension (PAH) is difficult to diagnose because of its nonspecific symptoms. Although echocardiography can reliably and rapidly recognize the presence of pulmonary hypertension, chest X ray (CXR) is more widely used because of its availability. The objective of this study was to find a parameter, which, by changing the scale of CXR, is still useful for detection ...

STUDY OBJECTIVE To determine the validity of the association between systemic hypertension (HTN) and unexplained pulmonary hypertension (PHTN) as identified with Doppler echocardiography. METHODS All patients with a reported systolic pulmonary artery pressure (SPAP) on routine Doppler echocardiography from our 1997 echocardiographic database were identified. Exclusions included all diseases k...

Introduction. Primary Sjögren's syndrome (pSS) is an autoimmune epithelitis. Pulmonary arterial hypertension (PAH) is an important and severe complication, which is encountered in many collagen tissue disorders. Early diagnostic strategies are required to define it at the asymptomatic stage. Doppler echocardiography is an important, noninvasive screening test for PAH diagnosis. Objective. The a...
