- Major Signaling Pathway in Scleroderma May Enable Effective Treatments, Cures
(Pulmonary Hypertension News)
As any scleroderma patient knows, the disease has no cure and no effective treatments exist. The main goal of current treatments is reducing inflammation which, often times, is not enough to provide relief to patients, especially those who have developed pulmonary hypertension as a result of thickened pulmonary arteries.

- Scleroderma Patients Benefit from Stem Cell Transplants Over Conventional Treatment
(Pulmonary Hypertension News)
Scleroderma patients, who are sometimes affected by pulmonary hypertension, are becoming routinely treated with stem cell transplants. Dr. Dinesh Khanna, at the annual European Congress of Rheumatology, previewed the results of the Autologous Stem Cell Transplantation International Scerloderma (ASTIS) trial evaluating 156 severe scleroderma patients randomized to receive a stem cell transplant or cyclophosphamide, a conventional drug used to treat some auto-immune diseases because it decreases the immune system’s response.

- New PAH-Related Hospitalization Study Released
(Pulmonary Hypertension News)
Lead author Charles Burger, MD, from the Mayo Clinic, and colleagues reported their findings in Chest. Data was gathered for 862 patients, and 490 (56.8%) experienced at least one hospitalization during their first three years post-diagnosis. 490 of the total had experienced at least one hospitalization during the 3-year follow-up period. 52.4% of the hospital admissions were PAH-related, while 43.7% were unrelated to the disease and 3.9% were due to undetermined causes. Half were related to the patients’ PAH, and the mean total number of days spent in the hospital was 15.3 days. Not only is a hospital stay burdensome to patients, but also it places a burden on the healthcare system.

- New technology removes blood clots
When a large blood clot was discovered attached to the end of a catheter inside the right atrial chamber of a patient's heart, doctors faced a daunting challenge. If the clot came loose, the consequences would likely be catastrophic for the patient, who suffered from pulmonary hypertension - a dangerous narrowing of blood vessels connecting the heart and lungs.
But experts at the UC San Diego Sulpizio Cardiovascular Center (SCVC) are now able to save patients like this one from potentially fatal outcomes by using a new technology capable of removing blood clots, infected masses or foreign bodies from major cardiac blood vessels without performing open-heart surgery.....

- The LARIAT trial: PAH clinical trial using bardoxolone methyl
The molecular and pharmacological effects of bardoxolone methyl are broad through its induction of Nrf2 and suppression of NF-κB. Bardoxolone methyl may therefore address multiple facets of the pathophysiology of PAH because it suppresses activation of proinflammatory mediators, enhances endothelial NO bioavailability, improves metabolic dysfunction, suppresses vascular proliferation, and prevents maladaptive remodeling. Furthermore, while existing therapies primarily target only smooth muscle cells, bardoxolone methyl targets multiple cell types relevant to PAH, including endothelial cells, smooth muscle cells, and macrophages.
This is a two-part study sponsored by Reata Pharmaceuticals of Irving, TX....

- Failure Of Health Information Technology
An article published in the University of Las Vegas Law Journal looks at the failure of health information technology to revolutionize medical care. This failure is something unexpected since the introduction of massive computerized information technology has changed just about every other industry. It only makes sense. Get all the information in a person's medical record together in a single bundle: history, physical, lab work, imaging such as x-rays, CT scans and MRIs, and so on. It will all be organized and can be followed without duplication. It only makes sense to do this until it is tried in real life.

- Corticosteroids and Transition to Delirium in Patients With Acute Lung Injury
Delirium is common in mechanically ventilated patients in the ICU and associated with short- and long-term morbidity and mortality. The use of systemic corticosteroids is also common in the ICU. Outside the ICU setting, corticosteroids are a recognized risk factor for delirium, but their relationship with delirium in critically ill patients has not been fully evaluated. We hypothesized that systemic corticosteroid administration would be associated with a transition to delirium in mechanically ventilated patients with acute lung injury.
