Sickle cell disease is a blood disorder wherein a person's red blood cells are changed from the normal disc shape into the shape of rigid sickles. While normal red blood cells are able to deform and squeeze through narrow blood vessels, these sickle cells can cause blockages and cut off the flow of blood to certain areas of the body, resulting in tissue death and damage to various organs. The condition also causes anemia, as the sickle cells have a much shorter lifespan than normal red blood cells, and the body's red blood cell production is unable to match this rapid loss.
Diabetes mellitus type 2, also known as adult-onset diabetes, is the most common form of diabetes, comprising 90% of all cases. The rate of type 2 diabetes has increased markedly over the past several decades, with 285 million people now suffering from the disease.
Chemotherapy is a mainstay of treatment for lymphoma, a cancer of the white blood cells. While chemotherapy drugs can often be very effective at treating certain forms of lymphoma, these medications are also highly toxic to the rest of the body, often resulting in a variety of serious and debilitating side effects.
Looking at what people are searching might find previously undetected side effects of drugs.
After all, many people who take a particular drug will search for it online to find out what the side effects are or whether it interacts with other drugs they're taking; if you mysteriously get a symptom, you're often going to look online to see what could cause it. Therefore, we'd expect searches for a drug to correlate with side effects from that drug-- even side effects we don't know about.
When you go to a hospital, the last thing you'd expect is to leave in worse shape than when you were admitted. Yet a new tool for tracking adverse events at hospitals has shown that they may be ten times more common than previously reported, occurring in up to a third of hospital admissions.
A doctor has discovered a molecular mechanism that protects people from Parkinson's disease.
Parkinson's disease is the most common movement disorder; people with Parkinson's often shake and find it difficult to walk. In about 10% of cases, Parkinson's disease is caused by mutations in specific genes, one of which is called “parkin.”
For people with severe food allergies, the risk of sudden and unexpected death is everywhere around them. When exposed to even trace amounts of allergens such as nuts, eggs, milk, or wheat, they can suffer a rapid, full-body immune response, potentially leading to shock, respiratory collapse and heart failure. 90,000 people visit the emergency room each year due to such severe reactions, known as anaphylaxis, and 100 to 200 die of it.
The Centers for Disease Control have recently warned that infections from deadly antibiotic-resistent bacteria are on the rise. Enterobacteriaceae is a family of bacteria that includes well-known bacteria like E. coli and salmonella. Over the past decade, however, the enterobacteriaceae have become resistant to carbapenem, an antibiotic usually used as a last resort.
Could a simple dietary change save your life? A recent study in the New England Journal of Medicine found that a Mediterranean diet may reduce the risk of heart attack, stroke, or death from cardiovascular causes.
