Men with long-term HIV infections at higher risk of developing plaque in their coronary arteries

Men with long-term HIV infections are at higher risk than uninfected men of developing plaque in their coronary arteries, regardless of their other risk factors for coronary artery disease, according to results of a study led by Johns Hopkins researchers. A report on the research appears in the April 1 issue of Annals of Internal Medicine.

Women who have 4 or more live births more likely to show early signs of heart disease

Women who give birth to four or more children are much more likely to have evidence of plaque in their heart or thickening of their arteries - early signs of cardiovascular disease - compared with those having fewer pregnancies, according to research to be presented at the American College of Cardiology's 63rd Annual Scientific Session.

New finding reinforces importance of developing healthy eating habits early in life

Women who ate a diet high in fresh fruits and vegetables as young adults were much less likely to have plaque build-up in their arteries 20 years later compared with those who consumed lower amounts of these foods, according to research to be presented at the American College of Cardiology's 63rd Annual Scientific Session.

New method can identify cancer's visible precursors with 97% certainty

Pancreatic cancer is often detected at a late stage, which results in poor prognosis and limited treatment options. Researchers at The University od Gothenburg, Sweden, have now developed a method which identifies the cancer's visible precursors with 97% certainty. The method, which is expected to aid in the early discovery of the cancer as well as minimize the risk of unnecessary surgery, may be introduced in patient care within five years.

New insight into germline EGFR T790M mutation in familial non-small cell lung cancer

Two studies are providing new insight into germline epidermal growth factor receptor (EGFR) T790M mutation in familial non-small cell lung cancer (NSCLC). The findings suggest the need for tailored approaches for early detection and treatment, as well as for genetic testing to identify carriers.

Imaging cancer in children using MRI: an interview with Dr. Heike E. Daldrup-Link, Stanford University School of Medicine

There have been a number of scientific publications recently that suggest that the radiation exposure from imaging tests can induce secondary cancers later in life.

Physicists recommend new strategies to make computed tomography safer

UC Davis clinicians and physicists have recommended new strategies to make computed tomography (CT) safer, including adoption of a new metric for dose measurement, ways to manage exposure protocols that differ by CT brand and specific approaches to reduce exposure during needle biopsies.

Researchers use "big data" analytics to predict triple-negative breast cancer and other cancers with 95% accuracy

Researchers at Case Western Reserve University and colleagues used "big data" analytics to predict if a patient is suffering from aggressive triple-negative breast cancer, slower-moving cancers or non-cancerous lesions with 95 percent accuracy.

Top medical organizations urge CMS to provide full Medicare coverage for LDCT screening

In a joint response to the Centers for Medicare & Medicaid Services (CMS) National Coverage and Analysis Group, the Lung Cancer Alliance, The Society of Thoracic Surgeons, American College of Radiology (ACR) and 38 other medical organizations called on CMS to quickly provide national Medicare coverage of low-dose computed tomography (LDCT) screening for patients at high risk for lung cancer.

CT scans predict effectiveness of chemotherapy for pancreatic cancer

Computed tomography (CT) scans routinely taken to guide the treatment of pancreatic cancer may provide an important secondary benefit. According to new research from The University of Texas MD Anderson Cancer Center, the scans also reflect how well chemotherapy will penetrate the tumor, predicting the effectiveness of treatment.

Prehospital stroke alerts can shorten time to emergency treatment

Prehospital stroke alerts by emergency medical services (EMS) personnel can shorten the time to effective treatment with "clot-busting" drugs for patients with stroke, according to a report in the March issue of Neurosurgery, official journal of the Congress of Neurological Surgeons.

Noninvasive imaging with MRI of carotid artery plaque accurately predicts future cardiovascular events

Noninvasive imaging of carotid artery plaque with MRI can accurately predict future cardiovascular events like strokes and heart attacks in people without a history of cardiovascular disease, according to a new study published online in the journal Radiology.

3-D imaging of two different mouse models helps understand Apert Syndrome development

Three dimensional imaging of two different mouse models of Apert Syndrome shows that cranial deformation begins before birth and continues, worsening with time, according to a team of researchers who studied mice to better understand and treat the disorder in humans.

New 256-slice CT scanner to predict potential heart attack in one second

What can you do in one second? Snap your fingers, blink your eyes, or get a diagnostic scan on a 256-slice computed tomography (CT) scanner? You can do all of those things in one second, but the one that may help save your life is the 256-slice CT scan.

iASSIST device improves surgical precision, accuracy in total knee replacements

Each year, approximately 600,000 total knee replacement procedures are performed in the United States, a number that is expected to rise exponentially in the next decade as the population ages. Successful surgeries require precise alignment in the knee, a challenging task made even more daunting by the expected rise in procedures. To help meet this demand, UC San Diego Health System is the first in the nation to use iASSIST, a computer navigation system with Bluetooth-like technology that improves surgical precision and accuracy in total knee replacements, decreasing the need for revision surgery.

New radiation-free MRI test effectively diagnoses cancer in children

A new type of whole-body magnetic resonance imaging test could be an alternative to standard positron emission tomography/computed tomography imaging for assessing cancer in children and young adults, but without exposure to radiation that has been shown to increase the risk of secondary cancers in later life.
