Researchers have long known that cancerous tumors grow collections of abnormal blood cells, the fuel that feeds this disease and keeps it growing. Now, new evidence in an animal model suggests that blood vessels in the fat tissue of obese individuals could provide the same purpose - and could provide the key to a new way for people to lose weight.

Researchers at Albert Einstein College of Medicine of Yeshiva University have developed a therapy for pancreatic cancer that uses Listeria bacteria to selectively infect tumor cells and deliver radioisotopes into them. The experimental treatment dramatically decreased the number of metastases (cancers that have spread to other parts of the body) in a mouse model of highly aggressive pancreatic cancer without harming healthy tissue.

Children can get five to 10 colds each year, so it's not surprising that adults often turn to over-the-counter cough and cold medicines to relieve their little ones' symptoms. But a new University of Michigan poll shows that many are giving young kids medicines that they should not use.

A massive study analyzing gene expression data from 22 tumor types has identified multiple metabolic expression changes associated with cancer. The analysis, conducted by researchers at Columbia University Medical Center, also identified hundreds of potential drug targets that could cut off a tumor's fuel supply or interfere with its ability to synthesize essential building blocks.

Nearly 30 percent of women failed to pick up their bisphosphonate prescriptions, a medication that is most commonly used to treat osteoporosis and similar bone diseases, according to a Kaiser Permanente study published this week in the journal Osteoporosis International. The failure to pick up these newly prescribed medications, called primary nonadherence, can lead to an increased risk of fractures for these patients.

National Institutes of Health (NIH) scientists studying an emerging coronavirus have found that a combination of two licensed antiviral drugs, ribavirin and interferon-alpha 2b, can stop the virus from replicating in laboratory-grown cells. These results suggest that the drug combination could be used to treat patients infected with the new coronavirus, but more research is needed to confirm this preliminary finding.

A study published in the European Heart Journal found no evidence that digoxin increases mortality in patients with atrial fibrillation (AF), the opposite of results just published by another group in the same journal analyzing the same data. Older patients with AF also often have heart failure, and digoxin is approved to treat both conditions.
