Scientists at the Walter Reed Army Institute for Research demonstrated that biomarkers associated with traumatic brain injury were elevated among law enforcement and military personnel, particularly in active duty participants with longer duration of service. Most notably, these elevated biomarker levels were observed in individuals without a diagnosed brain injury or concussion.
Hypertension is a common medical condition and a primary cause of cardiovascular diseases and stroke worldwide. Unfortunately, as Professor Wei-Li Zhang of the Chinese National Center for Cardiovascular Diseases notes, "the unaffordability of drugs is a major barrier to medication adherence among patients living in low- and middle-income areas."
DURHAM, N.C. - When patients complain of coughing, runny nose, sneezing and fever, doctors are often stumped because they have no fundamental tool to identify the source of the respiratory symptoms and guide appropriate treatments.
A new study published in Medical Care Research and Review found that the Affordable Care Act, which expanded Medicaid programs to cover people previously uninsured, provided a financial boost to hospitals.
The study conducted by faculty at the Colorado School of Public Health on the University of Colorado Anschutz Medical Campus is the first to investigate the effects of Medicaid expansion by comparing estimates using data from both the Internal Revenue Service (IRS) and the Centers for Medicare and Medicaid Services (CMS).
BOSTON - Researchers at Massachusetts General Hospital (MGH) have identified the protein "signature" of severe COVID-19, which they describe in a new study published in Cell Reports Medicine. "We were interested in asking whether we could identify mechanisms that might be contributing to death in COVID-19," says MGH infectious disease expert Marcia Goldberg, MD, who studies interactions between microbial pathogens and their hosts, and is senior author of the study.
BOSTON - Researchers from Massachusetts General Hospital (MGH) appear to have solved the 120-year-old mystery surrounding the failing health of famed Antarctic explorer Sir Ernest Shackleton over the course of his daring expeditions to Antarctica in the early part of the twentieth century.
Researchers have found that people who live beyond 105 years tend to have a unique genetic background that makes their bodies more efficient at repairing DNA, according to a study published today in eLife.
This is the first time that people with 'extreme longevity' have had their genomes decoded in such detail, providing clues as to why they live so long and manage to avoid age-related diseases.
TAMPA, Fla. (May 4, 2021) -- Repetitive transcranial magnetic stimulation, or rTMS, was FDA approved in 2008 as a safe and effective noninvasive treatment for severe depression resistant to antidepressant medications. A small coil positioned near the scalp generates repetitive, pulsed magnetic waves that pass through the skull and stimulate brain cells to relieve symptoms of depression. The procedure has few side effects and is typically prescribed as an alternative or supplemental therapy when multiple antidepressant medications and/or psychotherapy do not work.
Relatives of the giant crocodile might have been kings of the waterways during the Cretaceous period, eating anything--including dinosaurs--that got a little too close to the water's edge, but the largest of these apex predators still started off small. Figuring out how these little crocs grew up in a world surrounded by giants is no small task. Now crocs fossils from Texas are shedding light on how these animals changed their diets as they grew, helping them find a place of their own in environments alongside their bigger, badder relatives.
Scientists have shed light on why some people who have a stroke do not also have abnormal heart rhythms, even though their hearts contain similar scar tissue.
Their results, published today in eLife, could help identify the best treatments for people who might be at risk of recurrent stroke, new heart disorders, or both.
The human immune system doesn't just protect our health, it reflects it. Each encounter with a potential disease-causing agent causes the body to produce specific immune agents -- proteins known as antibodies and T-cell receptors -- tailor-made to recognize and destroy the invader. Tasked with preventing re-infection, antibodies and T-cell receptors (TCR) from your previous encounters circulate throughout the body indefinitely, like a record of your personal medical history that you carry inside of you.
PHILADELPHIA - Lung cancer is the third most common cancer in the U.S. and the leading cause of cancer death, with about 80% of the total 154,000 deaths recorded each year caused by cigarette smoking. Black men are more likely to develop and die from lung cancer than persons of any other racial or ethnic group, pointing to severe racial disparities.
Researchers at AMBER, the SFI Centre for Advanced Materials and BioEngineering Research, and from Trinity's School of Physics, have developed next-generation, graphene-based sensing technology using their innovative G-Putty material.
The team's printed sensors are 50 times more sensitive than the industry standard and outperform other comparable nano-enabled sensors in an important metric seen as a game-changer in the industry: flexibility.
A state of the art plenary session during the Pediatric Academic Societies (PAS) 2021 Virtual Meeting will bring together national experts on child poverty, racism and racial inequities, immigrant health, Native American culture, and environmental threats to discuss the intersectionality of child poverty.
Next-generation gene sequencing (NGS) technologies --in which millions of DNA molecules are simultaneously but individually analyzed-- theoretically provides researchers and clinicians the ability to noninvasively identify mutations in the blood stream. Identifying such mutations enables earlier diagnosis of cancer and can inform treatment decisions.
