No improvements with losmapimod after heart attack

Mon, 04/04/2016 - 10:10pm
Patients taking losmapimod, an anti-inflammatory drug currently being developed, for 12 weeks following a heart attack did not show improvements in the trial's primary endpoint, the rate of cardiovascular death, subsequent heart attack or urgent coronary revascularization, which includes placement of a stent or coronary artery bypass surgery, according to new research.

Device that detects congestion in the lung improves heart failure outcomes

Mon, 04/04/2016 - 10:10pm
In patients with heart failure, use of an investigational device that monitors the accumulation of fluid in the lungs appeared to cut heart failure-related hospitalizations by more than half, meeting the study's primary endpoint, and reduced deaths from any cause by 39 percent per year compared with standard assessment and treatment, researchers reported.

New device for heart failure patients fails to improve primary outcomes

Mon, 04/04/2016 - 10:10pm
A new implantable medical device intended to help patients with heart failure by stimulating the vagus nerve did not significantly reduce rates of heart failure-related hospitalization or death from any cause in a study presented at the American College of Cardiology's 65th Annual Scientific Session.

Cancer research shows promise for combating deadly lung cancer

Mon, 04/04/2016 - 10:09pm
Blocking the blood supply of small cell lung cancer tumors may help reduce their growth and delay the regrowth process after treatment, new research indicates. Small cell lung cancer is considered the most lethal of all lung cancers.

No benefit from addition of aliskiren to 'gold standard' ACE inhibitor

Mon, 04/04/2016 - 10:08pm
In one of the largest trials ever conducted in patients who have heart failure with reduced ejection fraction -- a measure of the heart's ability to pump blood -- the investigational drug aliskiren failed to show superiority over full-dose treatment with the existing 'gold standard' therapy, the angiotensin-converting enzyme inhibitor enalapril, researchers reported.

Precision medicine brings new hope to those with advanced urothelial cancer

Mon, 04/04/2016 - 10:08pm
Five of six patients with advanced metastatic urothelial cancer and one of two specific genetic abnormalities responded to treatment with afatinib, approved in 2013 for lung cancer. One patient with both mutations had stable disease for 16 months. None of the other 17 patients had a significant response. Time to disease progression with afatinib was much longer for patients carrying certain genetic abnormalities.

To treat a leading cause of osteoporosis, surgery is better than widely used medications

Mon, 04/04/2016 - 10:08pm
A leading cause of the bone-loss disease osteoporosis is hyperparathyroidism. Doctors commonly treat this using a class of prescription drugs called bisphosphonates, which are supposed to strengthen bones. A new study found those drugs actually increase the risk of fracture, meaning that taking them is worse than doing nothing at all. The research also revealed that patients who have surgery to remove the overactive parathyroid glands have fewer subsequent bone fractures.

Severe case of Ebola virus disease described by doctors

Mon, 04/04/2016 - 10:08pm
For more than a month in 2015, a multidisciplinary team of clinicians treated a critically ill patient who had contracted Ebola virus disease in Sierra Leone. A new report by the medical caregivers details the clinical course of the 34-year-old American healthcare worker who was admitted to the NIH Special Clinical Studies Unit on day seven of his illness. The patient survived his illness with intensive supportive care, despite multi-organ failure.

Yelp reviews can enhance government reports on hospital quality, study suggests

Mon, 04/04/2016 - 10:07pm
Yelp reviews of hospitals cover topics not found in the federal government's survey of patients' hospital experiences, according to the results of a new study. The additional information, which the authors say tends to be strongly linked to positive or negative reviews from Yelp contributors, could influence patient decision making on where to receive hospital care, and provide valuable information to hospital administrators, caregivers, and policymakers.
