Body
Scientists have shown for the first time that the brain is involved in the development of a heart condition called Takotsubo syndrome (TTS). They found that regions of the brain responsible for processing emotions and controlling the unconscious workings of the body, such as heart beat, breathing and digestion, do not communicate with each other as well in TTS patients as in healthy people.
DURHAM, NC - Researchers today presented results from the HPTN 071 (PopART) study at the annual Conference on Retroviruses and Opportunistic Infections (CROI) in Seattle. The study examined the impact of a package of HIV prevention interventions on community-level HIV incidence in urban and peri-urban communities in Zambia and South Africa.
Bundled payments have been touted as mechanisms to optimize quality and costs. A prior feasibility study evaluating bundled payments for screening mammography episodes predated widespread adoption of digital breast tomosynthesis (DBT). A new study, published online in the Journal of the American College of Radiology (JACR), explores an episodic bundled payment model for breast cancer screening that reflects the emerging widespread adoption of DBT.
CLEMSON, South Carolina -- By loading a chelation drug into a nano-sized homing device, researchers at Clemson University have reversed in an animal model the deadliest effects of chronic kidney disease, which kills more people in the United States each year than breast or prostate cancer.
When kidneys stop working properly, calcium builds up in artery tissue, leading to heart disease. Although nearly half a million Americans receive kidney dialysis, heart disease is the leading cause of death for people with chronic kidney disease.
American smokers mistakenly think that using snus, a type of moist snuff smokeless tobacco product, is as dangerous as smoking tobacco, according to a Rutgers study.
Each year in the United States, more than 600,000 children are seen in emergency rooms due to traumatic brain injury, a disruption to the normal function of the brain caused by a bump, blow or jolt to the head. Severe TBI results in approximately 7,000 childhood deaths annually, while survivors of the condition may suffer from long-term health conditions such as seizures, learning difficulty and communication disorders.
Researchers at American University have developed a new, highly sensitive rapid genetic test that can determine whether bacteria carries a gene that causes resistance to two common antibiotics used to treat strep throat and other respiratory illnesses. The scientists show that the new method works as accurately as culture-based methods but gives results in minutes, not hours or days. The research has been published in BMC Infectious Diseases.
A team of University of Central Florida researchers has overcome a long-standing problem in laser science, and the findings could have applications in surgery, drilling and 3D laser mapping.
Using the principle of supersymmetry, they have developed the first supersymmetric laser array. Their findings were published recently in the journal Science.
Supersymmetry is a conjecture in physics that says every particle of matter, such as an electron, has one or more superpartners that is the same except for a precise difference in their momentum.
A U.S.-funded initiative to improve quality of care and referrals during pregnancy and childbirth in Indonesia resulted in significant reductions in maternal and newborn mortality at participating hospitals, according to a new study led by scientists at the Johns Hopkins Bloomberg School of Public Health.
Delaying or witholding antibiotics for over 65s with symptoms of urinary tract infection (UTI) appears to be associated with higher risk of bloodstream infection (sepsis) and death, finds a study published by The BMJ today.
The findings suggest that older adults (especially men aged over 85) should start taking antibiotics as soon as possible after diagnosis to prevent serious complications.
Many antibiotic courses prescribed for common infections treated in English primary care (general practices and community services) exceed the recommended guidelines, reveals a study in The BMJ today.
Treatment courses were 1.3 million days beyond the durations recommended by guidelines, with most excess days due to treatment for respiratory conditions.
Exercise may play a role in reducing the growth of colon cancer cells according to new research published in The Journal of Physiology. The study found that after a short session of high intensity interval training (HIIT), growth of colon cancer cells was reduced, and this also increased indicators of inflammation.
The AIDS Clinical Trials Group (ACTG), the world's largest and longest-established HIV research network, funded by NIAID at the U.S. NIH, will make 11 oral and 19 poster presentations at CROI 2019 (Seattle, March 4-7). Several have the potential to influence clinical practice and guidelines for care.
By estimating a statistical model for male and female marathon world record progressions, Dr Angus also found that 1:58.05 is likely the fastest time that any living human being will be able to run this distance.
Published today in Medicine and Science in Sports and Exercise, the American College of Sports Medicine's flagship journal, results show that the chance of a female athlete ever breaking the two-hour mark is less than 1 in 100, with the fastest all-time female marathon time estimated to be 2:05.31.
People who suffer from obesity and type 2 diabetes are more likely to become victims of infectious diseases. Both conditions affect the immune system and hence increase the risk of infections. Scientists have long sought a deeper understanding of the mechanism underlying this weakness in the immune system of obese and diabetic individuals.
