A new Harvey L. Neiman Health Policy Institute study assesses temporal and patient-level differences in paracentesis and thoracentesis procedures performed on Medicare beneficiaries by radiologists and non-radiologists with respect to overall procedure volume, day of week, and patient complexity. The study is published online in Journal of Vascular and Interventional Radiology.
Researchers at the University of Delaware have identified ammonia as a source for engineering fuel cells that can provide a cheap and powerful source for fueling cars, trucks and buses with a reduced carbon footprint.
Advancements in genetic testing mean ongoing problems need to be addressed.
A new study from Penn researchers has identified a key regulator of a process that controls skin regeneration, which can control whether cells turn into a common skin cancer.
Heavy cigarette smokers with at least a 20 pack-year smoking history can reduce their risk of cardiovascular disease (CVD) by 39% within five years if they quit, according to a study published today in the Journal of the American Medical Association (JAMA).
Monitoring and tracking biological threats or epidemics require the ability to carry out tests in the field during austere situations. Expensive laboratory equipment is often unavailable in these settings, so inexpensive point-of-care technology is needed. Ordinary paper is often used, since it’s cheap, portable and widely available. However, paper poses some problems that hinder its usefulness. In this week’s Biointerphases, investigators report a technique that greatly improves the performance of paper-based point-of-care technologies.
Telemedicine programs provide an effective alternative to in-person clinic visits for follow-up evaluation after plastic surgery procedures for patients in rural areas, reports a study in the August issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).
Vitamin D deficiency in middle childhood could result in aggressive behavior as well as anxious and depressive moods during adolescence, according to a new University of Michigan study of school children in Bogotá, Colombia.
Merkel cell carcinoma (MCC) is a rare, aggressive skin tumor that is diagnosed in approximately 2,000 people each year in the United States. Since MCC affects so few people, it is difficult to study the genetic factors that lead to its development and how those factors correlate with response to therapy. However, Moffitt Cancer Center researchers have developed the largest descriptive genomic analysis of MCC patients to date, in collaboration with Foundation Medicine and the Dana Farber Cancer Institute. Their analysis, published in Clinical Cancer Research, will provide important information to improve the care and treatment of MCC patients for many years to come.
Especially in women who have had multiple pregnancies, widening and thinning of the abdominal muscles may contribute to problems with the outcomes of abdominoplasty ("tummy tuck") surgery, reports a study in the August issue of Plastic and Reconstructive Surgery®, the official medical journal of the American Society of Plastic Surgeons (ASPS).
In a new study of seven people with Parkinson’s disease, Johns Hopkins Medicine researchers report evidence that deep brain stimulation using electrical impulses jumpstarts the nerve cells that produce the chemical messenger dopamine to reduce tremors and muscle rigidity that are the hallmark of Parkinson’s disease, and increases feelings of well-being.
An international team of scientists reviewed more than 10,000 published climate change studies and has reached a sobering conclusion. Birds and other animals cannot adapt fast enough to keep pace with climate change, throwing species survival in doubt.
A new study shows that older adults enthusiastically adopt on-demand rideshare technology options, which improves their access to medical care and overall quality of life. However, the cost of these services remain a challenge.
An international team of scientists, including climate scientists from Lawrence Berkeley National Laboratory, found that accounting for phosphorus-deficient soils reduced projected carbon dioxide uptake by an average of 50% in the Amazon, compared to current estimates based on previous climate models that did not take into account phosphorus deficiency.
-- A drug used to slow cognitive decline in adults with Alzheimer's disease appears to reverse brain inflammation and neuron damage in rats exposed to alcohol during adolescence.
New research shows that visitors to urban parks use happier words and express less negativity on Twitter than before their visit—and that their elevated mood lasts for up to four hours. The effect is so strong that it’s equivalent to the mood spike on Christmas, the happiest day each year on Twitter. With increasing urbanization and mood disorders, this research may have powerful implications for public health and urban planning.
A team of researchers led by the University of South Australia has discovered a way to find and beat superbugs, providing a critical breakthrough against many deadly infectious diseases.
Missouri S&T researchers are demonstrating a new concept to reconstruct holographic images by using a single two-dimensional material monolayer with the thickness of less than one nanometer. Their work could lead to the creation of smart watches with holographic displays, printed security cryptograms on bank notes and credit cards, and new possibilities for data storage.
Each year there are more than 200 million cases of malaria worldwide, a mosquito-borne disease caused by a parasite that brings on fever and body aches and, in some cases, more serious conditions such as coma and death. While the vast majority of these cases occur in sub-Saharan Africa and South Asia, the U.S. each year sees more than 1,500 cases, and currently there is limited access to an intravenously-administered (IV) drug needed for the more serious cases, according to a top malaria researcher at the University of Maryland School Medicine (UMSOM).
