Study assesses post-coronary artery bypass graft surgery atrial fibrillation and long-term survival

Atrial fibrillation is a common complication of cardiac surgery, occurring in 10 percent to 40 percent of patients. Recent studies show it to be associated with poorer health following surgery and poorer long-term survival. Furthermore, development of atrial fibrillation after cardiac surgery leads to average additional health care costs of $15,000 to $20,000.

NFAT protein plays a part in development of acute pancreatitis

It is likely that the protein is also highly significant for other inflammatory diseases. The research results have been published in the American journal Gastroenterology.

New intriguing knowledge on blood haemoglobin

Scientists at the research centre MEMBRANES at Aarhus University, Denmark, have completed an old puzzle, which since the 60s from many sides has been regarded as impossible to complete. The challenge was to solve the structure of the protecting protein complex that forms when haemoglobin is released from red cells and becomes toxic. This toxic release of haemoglobin occurs in many diseases affecting red cell stability, e.g. malaria.

Astellas Pharma receives FDA approval for Xtandi to treat metastatic CRPC

The U.S. Food and Drug Administration today approved Xtandi (enzalutamide) to treat men with late-stage (metastatic) castration-resistant prostate cancer that has spread or recurred, even with medical or surgical therapy to minimize testosterone.

Exposure to polychlorinated biphenyls could increase risk of asthma symptoms in children

Children who are exposed to polychlorinated biphenyls (PCBs), which were commonly used in a range of industrial products, could be at risk of an increase in asthma symptoms, according to new research.

Scientists show how pluripotent stem cells mobilize in wounded planarian worms

The skin, the blood, and the lining of the gut-adult stem cells replenish them daily. But stem cells really show off their healing powers in planarians, humble flatworms fabled for their ability to rebuild any missing body part. Just how adult stem cells build the right tissues at the right times and places has remained largely unanswered.

Researchers define new treatment for potentially fatal lung disease in patients with CVID

A team of researchers at the Medical College of Wisconsin and Children's Hospital of Wisconsin Research Institute defined a new treatment for a potentially fatal lung disease in patients with a primary immunodeficiency known as common variable immunodeficiency (CVID).

The safety of trainee surgeons: an interview with Prof Calvin Coffey

Surgical training begins at an undergraduate medical student level where students are involved in operations to a minor degree, and educated using a combination of didactic and problem-based approaches.

Study reports flaws in design, analysis, and interpretation of Lyme disease

Most doctors treat Lyme disease with antibiotics for two to four weeks after diagnosis, but if symptoms persist after that, medical guidelines recommend against antibiotic retreatment. That recommendation may not be warranted. A newly published statistical review of the four studies upon which those guidelines are based reports flaws in design, analysis, and interpretation that call into question the strength of the evidence against retreatment.

Well-known protein plays central role in development of acute pancreatitis

There is now a clear target for the treatment of acute pancreatitis, according to researchers at Lund University in Sweden, who have discovered that a well-known protein plays a central role in the development of the disease. It is likely that the protein is also highly significant for other inflammatory diseases.

Tunes and T-shirts for cardiac rehabilitation

Two studies presented at the European Society of Cardiology Congress in Munich, Germany, showed how researchers are developing innovative approaches to help patients get the most out of cardiac rehabilitation.

Prenatal exposures to polyfluoroalkyl compounds may lead to obesity in babies

Pregnant women who are highly exposed to common environmental chemicals - polyfluoroalkyl compounds (PFCs) - have babies that are smaller at birth and larger at 20 months of age, according to a study from Emory University's Rollins School of Public Health published online in the August 30 edition of Environmental Health Perspectives.

Scientists identify specific role of RESA protein in modulating blood circulation

When the parasite responsible for malaria infects human red blood cells, it launches a 48-hour remodeling of the host cells. During the first 24 hours of this cycle, a protein called RESA undertakes the first step of renovation: enhancing the stiffness of the cell membranes.

Research identifies new pathway to target with anti-inflammatory drugs

Scientists' discovery of an important step in the body's process for healing wounds may lead to a new way of treating inflammation.

Researchers identify several genetic factors linked to C-reactive protein

African Americans have higher blood levels of a protein associated with increased heart-disease risk than European Americans, despite higher "good" HDL cholesterol and lower "bad" triglyceride levels. This contradictory observation now may be explained, in part, by a genetic variant identified in the first large-scale, genome-wide association study of this protein involving 12,000 African American and Hispanic American women.

Study explains why some cancer vaccines are not as effective as hoped

A research report published in the September 2012 issue of the Journal of Leukocyte Biology offers a possible explanation of why some cancer vaccines are not as effective as hoped, while at the same time identifies a new therapeutic strategy for treating autoimmune problems. In the report, scientists suggest that cancer, even in the very early stages, produces a negative immune response from dendritic cells, which prevent lymphocytes from working against the disease.

Glaucoma and cell death: an interview with Dr. Vivek Gupta

Glaucoma is normally caused by increased pressure of aqueous humour fluid in the eye. A defining feature of this disease is destruction of a particular type of cells in the retina called retinal ganglion cells and excavation of the optic disc region.

Weill Cornell Medical College receives three new research grants for translational blood cancer study

Weill Cornell Medical College has been awarded three new research grants from the Leukemia & Lymphoma Society totaling $1.8 million. The funds will support critically-needed translational research for blood cancers, accelerating promising discoveries from the laboratory to the patient's bedside.

Renal artery stent revascularization reduces blood pressure in patients with severe hypertension

Patients with uncontrolled renovascular hypertension saw a significant improvement in their blood pressure with renal artery stent deployment. The multicenter HERCULES trial, evaluating the safety and effectiveness of the RX Herculink Elite Stent, found that patients with higher blood pressure levels at baseline had the most dramatic reduction in blood pressure following intervention.

Researchers discover new immune response mechanism during infection

Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered a new "first response" mechanism that the immune system uses to respond to infection. The findings challenge the current understanding of immunity and could lead to new strategies for boosting effectiveness of all vaccines. The study, conducted in mice, published online today in the journal Immunity.
