In a first-of-its-kind study, researchers found that the brain’s control center for a lost appendage can persist long after surgical amputation, which stands in stark contrast to longstanding theories about the brain’s ability to reorganize itself, also known as plasticity. Scientists from the National Institutes of Health (NIH) and their colleagues examined human brain activity before and after arm amputation and found that the loss of a limb does not prompt a large-scale cerebral overhaul. Published in the journal Nature Neuroscience, this study offers new insight into the mysterious phantom limb syndrome and could help guide the development of neuroprosthetics and pain treatments for people with limb loss.

A National Institutes of Health (NIH)-supported clinical trial has found that the outcome of treating complicated Staphylococcus aureus bloodstream infections with two intravenous (IV) doses of the antibiotic dalbavancin seven days apart is just as good as daily IV doses of conventional antibiotics over four to six weeks. Nearly 120,000 S. aureus bloodstream infections and 20,000 associated deaths occurred in the United States in 2017. The study results provide the clearest evidence to date for the safety and effectiveness of dalbavancin therapy for complicated S. aureus bloodstream infections, expanding the number of antimicrobial treatment options for clinicians and patients.

Adults who smoke cigarettes and are addicted to alcohol or other drugs were more likely to achieve sustained remission of their substance use disorder symptoms if they also quit smoking, according to scientists at the National Institutes of Health (NIH).  Based on their analysis of data from a large U.S. study of smoking and health, researchers believe the results clearly show the benefit of pairing smoking cessation with addiction recovery efforts.  

Researchers at the National Institutes of Health (NIH) have shown for the first time that a type of human papillomavirus (HPV) commonly found on the skin can directly cause a form of skin cancer called cutaneous squamous cell carcinoma (cSCC) when certain immune cells malfunction. cSCC is one of the most common cancers in the United States and worldwide. Previously, scientists believed HPV merely facilitated the accumulation of DNA mutations caused by ultraviolet (UV) radiation, usually the primary driver of cSCC. The findings were published today in The New England Journal of Medicine.

Scientists at the National Institutes of Health (NIH) and their colleagues at the University of California, San Diego, have found that fine-particulate air pollution, which includes pollution from vehicles and industry, was strongly associated with increased genomic changes in lung cancer tumors among people who have never smoked. By assembling the largest-ever whole-genome analysis of lung cancer in individuals who have never smoked, researchers were able to link air pollution exposure to increased cancer-driving and cancer-promoting genetic mutations. This could potentially lead to more prevention strategies for never-smokers.
