People with autoimmune disease have a higher complication rate after heart attack: Study
After a heart attack, people with an autoimmune disease were more likely to die, develop heart failure or have a second heart attack compared to people without an autoimmune disease, according to new research published today in the Journal of the American Heart Association.
Autoimmune diseases, are known to increase risk of cardiovascular disease, likely due to multiple factors. People with an autoimmune disease have a higher prevalence of traditional cardiovascular risk factors in addition to aspects of autoimmune disease that are also linked to higher cardiovascular risk and long-term use of steroid medications.

Multivitamins taken daily may improve brain function
Could taking a daily multivitamin help maintain cognitive health with aging and possibly prevent cognitive decline? According to new research from Wake Forest University School of Medicine, conducted in collaboration with Brigham and Women's Hospital in Boston, taking a daily supplement may improve cognition in older adults. The study also showed that daily use of a cocoa extract supplement does not benefit cognition.
According to the Alzheimer's Association, more than 6.5 million Americans are living with Alzheimer's disease, and 1 in 3 seniors die with the disease or another form of dementia. The study, published in Alzheimer's & Dementia, investigated whether taking a daily cocoa extract supplement or a daily multivitamin-mineral supplement reduces the risk of developing heart disease, stroke, cancer and other health outcomes.

Engineered enzyme against antibiotic-resistant anthrax
Antibiotic-resistant strains of the bacteria are of growing concern, and researchers are preparing to fight back. Now, a team reporting in ACS Infectious Diseases has taken a step toward the development of a therapeutic that can treat the infection in mice without antibiotics.
One type of B. anthracis, called the Ames strain, is particularly virulent because it can wrap itself in a protective capsule of poly-D-glutamic acid that acts like a cloak of invisibility, helping the bacteria evade the human immune system.

Air pollution can lead to arrhythmias in healthy teens
Breathing particulate matter (i.e., tiny particles suspended in the air) air pollution may trigger irregular heart rhythms (arrhythmias) in healthy teenagers, according to new research published today in the Journal of the American Heart Association.
The study examined the impact of breathing fine particulate matter on heart rhythms of adolescents. Fine particulates (PM2.5) are less than 2.5 microns in size and can easily be inhaled deep into the lungs and even enter the bloodstream. Once inhaled, the pollutants irritate the lungs and blood vessels around the heart, and previous research has suggested that over time, pollutants increase the process of disease in the arteries.
