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.

Solid-dominant lung cancer histology no barrier to segmentectomy

Complete resection with segmentectomy is as effective as lobectomy for patients with solid-dominant clinical stage IA lung adenocarcinoma, Japanese study findings suggest.

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.

PET eliminates approximately 50% of unnecessary surgeries in lung cancer patients

New quantitative data suggests that 30 percent of the surgeries performed for non-small cell lung cancer patients in a community-wide clinical study were deemed unnecessary.

Study lays groundwork for PET imaging studies on human Menkes disease

Scientists at the RIKEN Center for Life Science Technologies have used PET imaging to visualize the distribution in the body of copper, which is deregulated in Menkes disease, a genetic disorder, using a mouse model. This study lays the groundwork for PET imaging studies on human Menkes disease patients to identify new therapy options.

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.

FDA approves expansion of BIOTRONIK's ongoing ProMRI trial

BIOTRONIK, a leading manufacturer of cardiovascular medical devices, announced today that the Food and Drug Administration has approved the expansion of BIOTRONIK's ongoing ProMRI trial. The new phase of the trial (Phase C) will study the company's ProMRI technology in implantable cardioverter-defibrillator (ICD) devices.

Oncologists use mathematical model to develop treatment plans for cancer patients

Physics applies to everything. So when Vittorio Cristini, PhD, started researching cancer, he applied physics. The result he got was a set of mathematical equations that describe, for each person, how many of their tumor cells a cancer treatment could kill.

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.

Plaque in brain could guide treatment decisions for patients at risk for Alzheimer's

Brain imaging using radioactive dye can detect early evidence of Alzheimer's disease that may predict future cognitive decline among adults with mild or no cognitive impairment, according to a 36-month follow-up study led by Duke Medicine.

Researchers determine affected areas of brain using speech processing tests with aid of fMRT

The brain processes read and heard language differently. This is the key and new finding of a study at the University Department of Radiology and Nuclear Medicine at the MedUni Vienna, unveiled on the eve of the European Radiology Congress in Vienna (6 to 10 March).

Biodegradable scaffolds promote tissue growth during the healing process

Researchers from the University of Pittsburgh's Swanson School of Engineering and McGowan Institute for Regenerative Medicine (MIRM) are proposing that if 3-D printers, or additive manufacturing, can produce custom replacement parts for machines, why couldn't the same process create biodegradable tissue repair structures for the human body?
