Noninvasive imaging test may spare benign kidney tumor patients from unnecessary surgery

The latest in a series of studies led by researchers at Johns Hopkins Medicine shows that addition of a widely available, noninvasive imaging test called 99mTc-sestamibi SPECT/CT to CT or MRI increases the accuracy of kidney tumor classification.

Clemson University researcher receives NIH grant to advance study into abdominal aortic aneurysms

One of the top ten killers for men older than 55 is the target of Clemson University research that could lead to a new life-saving therapy and a better way of telling whether surgery is necessary.

3D-printed models provide cost-efficient tool to improve practical experience for surgeons

Cher Zhao recently had the rare opportunity to practice skills belonging to the most advanced surgeons: reconstructive cartilage grafting.

Study finds unnecessary referrals, testing in patients treated at hospital-based primary practices

Patients with common conditions such as back pain, headaches and upper respiratory infections are more likely to receive tests and services of uncertain or little diagnostic or therapeutic benefit--so-called low-value care--when they seek treatment in primary care clinics located at hospitals rather than at community-based primary care clinics, according to a nationwide study led by researchers at Harvard Medical School and the David Geffen School of Medicine at UCLA.

Hand-held EEG device can quickly assess brain bleeding in head injuries

In a clinical trial conducted among adults in 11 hospitals, researchers have shown that a hand-held EEG device approved in 2016 by the U.S. Food and Drug Administration that is commercially available can quickly and with 97 percent accuracy rule out whether a person with a head injury likely has brain bleeding and needs further evaluation and treatment.

Five simple tests provide more accurate assessment of heart-disease risk

Five simple medical tests together provide a broader and more accurate assessment of heart-disease risk than currently used methods, cardiologists at UT Southwestern Medical Center found.

Study finds direct link between increasing width of vestibular aqueduct and severity of child's hearing loss

It may be possible to predict the severity of hearing loss for children diagnosed with enlarged vestibular aqueduct, according to a new study published in JAMA-Otolaryngology-Head & Neck Surgery.

Researchers examine potential for microRNAs to detect gastrointestinal cancer in blood, bodily fluids

Blood tests that could detect cancer before it develops show promise for the future of screening and prevention, though researchers continue to test which cancer clues are good markers for diagnosis.

Tsimane indigenous South Americans have lowest prevalence of coronary atherosclerosis of any population yet studied

The Tsimane people – a forager-horticulturalist population of the Bolivian Amazon – have the lowest reported levels of vascular ageing for any population, with coronary atherosclerosis (hardening of the arteries) being five times less common than in the US, according to a study published in The Lancet and being presented at the American College of Cardiology conference.

CT scans reveal subclinical leaflet thrombosis in patients undergoing aortic valve replacement

About 12 percent of patients undergoing aortic valve replacement developed non-symptomatic blood clots around the valve leaflets (known as subclinical leaflet thrombosis) that reduced the motion of the valves, according to an observational study presented at the American College of Cardiology's 66th Annual Scientific Session.

CT lung cancer screening test for longtime smokers detects patient's tumor before symptoms

Dawn Andersen lost her husband to lung cancer, and as a longtime smoker herself, she also was at high risk for the disease.

UCLA study finding holds promise to prevent progressive cognitive decline in children with brain injury

A new biological marker may help doctors identify children at risk of poor outcomes after a traumatic brain injury, UCLA scientists report in a preliminary study.

Variation in hospital-level resources may impact diagnostic evaluation of children with appendicitis

At some hospitals, children receive better care in the daytime than they do at night for suspected appendicitis. This is the finding of a study to be published in the April 2017 issue of Academic Emergency Medicine, a journal of the Society for Academic Emergency Medicine.

Counseling and shared decision-making can enhance understanding of lung cancer screening

Lung cancer screening using a low-dose CT scan can be a lifesaving test for high-risk patients. While it offers clear benefits, incidental findings and radiation exposure mean there are some potential risks associated with yearly screening.

Hormone replacement therapy linked to lower risk of atherosclerosis and death in women

Hormone replacement therapy has long been controversial as studies have associated it with health benefits and risks. While some studies suggest that it lowers the risk of osteoporosis and improves some aspects of heart health, others link it to higher risk of cancer and stroke.

Study: Nonoperative management of abdominal gunshot wounds is safe option in selected patients

At one time, trauma surgeons considered an operation mandatory to treat gunshot wounds to the abdomen, but a study published online as an "article in press" on the Journal of the American College of Surgeons website has found that in selected patients, avoiding an operation--a practice known as nonoperative management--is an acceptable and effective treatment.

New online tool can help clinicians quantify minimal risk in patients with stable chest pain

A two year follow-up on a study involving more than 10,000 people with stable chest pain finds that an online tool can accurately predict which patients are likely to have normal non-invasive tests and remain free of cardiac events.

High paracardial fat volume linked to increased risk for heart disease in postmenopausal women

A higher volume of a certain type of fat that surrounds the heart is significantly associated with a higher risk of heart disease in women after menopause and women with lower levels of estrogen at midlife, according to new research led by the University of Pittsburgh Graduate School of Public Health.

Advances in imaging technology help diagnose more trauma patients with blunt cerebrovascular injuries

Advances in diagnostic imaging technology have meant that more trauma patients are being diagnosed with blunt cerebrovascular injuries, and as a result, stroke and related death rates in these patients have declined significantly over the past 30 years.
