Study: Blood test can predict postoperative stroke risk following cardiac surgery

The results of a blood test done immediately after heart surgery can be a meaningful indicator of postoperative stroke risk, a study by researchers at Wake Forest Baptist Medical Center has found.

Discovery may lead to new potential treatment for drug-resistant melanoma

In the last several years, targeted therapies - drugs that directly impact specific genes and proteins involved in the progression of cancer - have been approved for a wide variety of cancers, including melanoma, the deadliest form of skin cancer. Now, researchers at The Wistar Institute have discovered one way in which melanoma becomes resistant to a particular form of targeted therapy, and understanding this phenomenon may lead to a new melanoma target or prompt new designs of these treatments.

Vitamin D plays major role in preventing diabetes and atherosclerosis

In recent years, a deficiency of vitamin D has been linked to type 2 diabetes and heart disease, two illnesses that commonly occur together and are the most common cause of illness and death in Western countries. Both disorders are rooted in chronic inflammation, which leads to insulin resistance and the buildup of artery-clogging plaque.

Catheter ablation more beneficial to heart failure patients than Amiodarone treatment

Among patients with heart failure and atrial fibrillation, those who underwent catheter ablation were less likely to die, be hospitalized or have recurrent atrial fibrillation than patients taking a heart rhythm regulating drug, according to a study presented at the American College of Cardiology's 64th Annual Scientific Session.

Study reveals novel approach to treat breast cancer

A means of reprogramming a flawed immune response into an efficient anti-tumoral one was brought to light by the results of a translational trial relating to breast cancer. Thanks to the innovative combination of mathematical modelisation and experimentation, only 20 tests were necessary, whereas traditional experimentation would have required 596 tests to obtain the same results.

Patients who experience deadliest form of heart attack may benefit from angioplasty

Patients who experience the deadliest form of heart attack--ST segment elevation myocardial infarction (STEMI)--and suffer from substantial narrowing in multiple heart arteries may benefit from receiving angioplasty in constricted arteries not affected by the heart attack, thereby reducing the need for future angioplasty, according to research presented at the American College of Cardiology's 64th Annual Scientific Session.

Baroreflex activation therapy safe, effective for symptomatic advanced heart failure patients

Results of a clinical trial announced today at the American College of Cardiology Annual Scientific Session show a new type of therapy is safe and effective for symptomatic advanced heart failure patients who are already receiving optimum drug and device therapy.

Researchers find that exercise may slow tumor growth, improve chemotherapy

One way many cancers grow resistant to treatment is by generating a web of blood vessels that are so jumbled they fail to provide adequate oxygen to the tumor. With oxygen starvation, the tumor gains a sort of cloaking device that protects it from the toxic effects of chemotherapy drugs and radiation, which are designed to seek out well-oxygenated tissue.

Routine cardiac CT scan may help reduce heart attack risk

Routine heart scans for patients referred to cardiac clinics with chest pain could reduce heart attack rates, research suggests.

Study: Cancer drug may help reduce bleeding in HHT patients

A cancer drug that helps keep tumors from growing blood vessels may help patients with a rare genetic condition in which malformed vessels increase their risk for bleeding and anemia.

CT coronary angiography can accurately diagnose coronary artery disease

Use of computed tomography coronary angiography, which provides 3-D images of the heart, coupled with standard care allows doctors to more accurately diagnose coronary artery disease in patients presenting with chest pain, therefore, leading to more appropriate follow-up testing and treatments, according to research presented at the American College of Cardiology's 64th Annual Scientific Session.

New antibody treatment blocks immune signaling protein crucial to psoriasis

Many patients suffering from psoriasis showed significant recovery after just a single dose of an experimental treatment with a human antibody that blocks an immune signaling protein crucial to the disease, researchers report.

Yale researchers test new device that protects patients' brain during heart-valve replacement procedure

In the first multicenter trial of its kind, Yale researchers tested a new device that lowers the risk of stroke and cognitive decline in patients undergoing heart-valve replacement.

Mechanistic subtypes of IPAH revealed

Researchers have provided evidence for distinct processes underlying vasodilator-responsive and nonresponsive idiopathic pulmonary arterial hypertension.

'Turbocharged' protein holds promise in hemophilia gene therapy

Using gene therapy to produce a mutant human protein with unusually high blood-clotting power, scientists have successfully treated dogs with the bleeding disorder hemophilia, without triggering an unwanted immune response.

Glyconanoparticles may help reduce cell damage and inflammation after stroke

Materials resulting from chemical bonding of glucosamine, a type of sugar, with fullerenes, kind of nanoparticles known as buckyballs, might help to reduce cell damage and inflammation occurring after stroke.

Medicine-loaded nanoparticles could help patients achieve corneal transplant success

There are about 48,000 corneal transplants done each year in the U.S., compared to approximately 16,000 kidney transplants and 2,100 heart transplants. Out of the 48,000 corneal transplants done, 10 percent of them end up in rejection, largely due to poor medication compliance. This costs the health care system and puts undue strain on clinicians, patients and their families.

Organ-on-a-chip could replace use of animals to test drugs for safety and efficacy

When University of California, Berkeley, bioengineers say they are holding their hearts in the palms of their hands, they are not talking about emotional vulnerability.

Excess dietary sodium can adversely affect organs

You may think you're one of the lucky ones who can eat all the salty snacks and convenience foods you want and still register low numbers on the blood pressure cuff. But, new research suggests you may not be so lucky after all.

MDC scientists identify new molecular signaling pathway that regulates placental development

During pregnancy, the mother supplies the fetus with nutrients and oxygen via the placenta. If placental development is impaired, this may lead to growth disorders of the embryo or to life-threatening diseases of the mother such as preeclampsia, a serious condition involving high blood pressure and increased urinary protein excretion.
