Scientists identify new genetic mutations that can cause pulmonary arterial hypertension

Columbia University Medical Center (CUMC) scientists have identified new genetic mutations that can cause pulmonary arterial hypertension (PAH), a rare fatal disease characterized by high blood pressure in the lungs.

Study documents reversal of established medical practices in last decade

While there is an expectation that newer medical practices improve the standard of care, the history of medicine reveals many instances in which this has not been the case. Reversal of established medical practice occurs when new studies contradict current practice. Reporters may remember hormone replacement therapy as an example of medical reversal. A new analysis published in Mayo Clinic Proceedings documents 146 contemporary medical practices that have subsequently been reversed.

Clinical study shows that clopidogrel not effective in infants with congenital heart diseases

One of the largest clinical trials done in infants with congenital (present at birth) heart diseases, published in the New England Journal of Medicine, shows that the increasingly common practice of using the drug clopidogrel (Plavix-) to reduce shunt-related blood flow issues is not effective in the dose studied.

ECMO can be used on neonates with severe respiratory failure until lung transplantation, say scientists

Adults with end-stage respiratory failure and pulmonary hypertension requiring ECMO (extracorporeal membrane oxygenation) have been "bridged" toward lung transplantation with novel lung assist devices such as the Novalung.

AACN Practice Alert outlines evidence-based protocols related to bathing adult patients

The long-held tradition of using a basin, soap and water to bathe bed-bound hospitalized patients is no longer the recommended standard of practice, according to the American Association of Critical-Care Nurses.

Sildenafil does not improve exercise capacity in HF patients with preserved ejection fraction

Among patients with heart failure with preserved ejection fraction (a measure of heart function), administration of sildenafil for 24 weeks, compared with placebo, did not result in significant improvement in exercise capacity or clinical status, according to a study published online by JAMA.

High life inadvisable after Fontan procedure

Living at even a moderate altitude may have an adverse impact on the health and survival of patients who have undergone the Fontan procedure for single-ventricle anatomy, say researchers.

CHOP presents new findings on pediatric cardiovascular disease at AHA 2012

Physician-researchers from the Cardiac Center at The Children's Hospital of Philadelphia presented new findings on pediatric cardiovascular disease at the American Heart Association's Scientific Sessions 2012 in Los Angeles.

Exosomes alone could protect infants' lungs from dangerous inflammation

Researchers at Boston Children's Hospital have found that microscopic particles containing proteins and nucleic acids called exosomes could potentially protect the fragile lungs of premature babies from serious lung diseases and chronic lung injury caused by inflammation.

Experts blaze TRAIL for pulmonary arterial hypertension therapy

Researchers have shown that the cell signaling molecule tumor necrosis factor-related apoptosis-inducing ligand may be a potential therapeutic target for pulmonary arterial hypertension.

CT shows promise in predicting COPD exacerbation risk

Measurement of the pulmonary artery-to-aorta ratio can predict the risk for exacerbations in patients with chronic obstructive pulmonary disease, particularly those that require hospitalization, say the authors of a US study.

CT scan appears to predict risk of chronic obstructive pulmonary disease exacerbations

The respective size of two major arteries, visible on a simple computed tomography, or CT, scan, is a strong predictor of the risk of exacerbation of chronic obstructive pulmonary disease, according to new research from the University of Alabama at Birmingham published online Sept. 3, 2012, in the New England Journal of Medicine.

JRD receives FDA priority review designation for XARELTO sNDAs to treat PE, DVT

Janssen Research & Development, LLC (Janssen R&D) announced today the U.S. Food and Drug Administration (FDA) has assigned a priority review designation to the supplemental New Drug Applications (sNDAs) filed on May 2, 2012 for XARELTO (rivaroxaban), an oral anticoagulant, seeking new indications to treat patients with deep vein thrombosis (DVT), pulmonary embolism (PE), and to prevent recurrent DVT and PE.

EKOS launches two landmark clinical studies on pulmonary embolism

EKOS Corporation today announced the launch of two more landmark clinical studies named SEATTLE I & II, intended to further establish the safety and efficacy of its unique, ultrasound-accelerated thrombolysis in treating patients with life-threatening pulmonary embolism.

Innate patient factors, overall morbidity affect neurodevelopment in infants with single-ventricle disease

In the largest multicenter clinical trial of children undergoing early-stage surgery for single-ventricle heart defects, differences in intraoperative management did not significantly affect neurodevelopmental outcomes at 14 months of age. Instead, the strongest influences were innate patient characteristics and general medical morbidity during the child's first year of life.

Addition of two MRI sequences to MRPA improves detection of pulmonary embolism

New research shows that the addition of two magnetic resonance imaging (MRI) sequences to a common MR angiography technique significantly improves detection of pulmonary embolism, a potentially life-threatening condition traditionally diagnosed through computed tomography.
