Experimental Test Can Spot Autism in Infancy

Posted 5 days ago by Drugs.com

WEDNESDAY, Feb. 15, 2017 – In what they call a first, researchers say they can predict whether some infants under the age of 1 will actually develop autism in their second year. The new experimental technique, using standard brain screening, is designed to focus solely on newborns known to be at high risk for autism because they have an older sibling who has it. But the diagnostic breakthrough addresses a key problem that has confounded efforts to effectively screen for autism as quickly as possible: Babies typically don't show clear outward signs of the disorder until nearly the end of their second year of life. By using scans to peek into the shifting size, surface area and thickness of certain parts of a baby's cerebral cortex as a baby hits the 6-month and 12-month mark, investigators found that they could forecast autism risk with 90 percent accuracy. "These findings suggest a ... Read more

Many Women Skip Mammograms After False-Positive Result

Posted 12 days ago by Drugs.com

THURSDAY, Feb. 9, 2017 – The trauma of receiving a false-positive result from a mammogram may lead many women to delay or skip their next screening, a new study finds. A false-positive result means that an aberration on a mammogram looks like it might be cancer. But after tests – such as added imaging or biopsy – it turns out to be benign. In the meantime, however, the patient may go through distress and various procedures, and decide to delay or skip her next mammogram. That's a potentially fatal mistake, breast cancer experts said, because detecting tumors early can save lives. "Unfortunately, for women over age 50, just skipping a mammogram every other year would miss up to 30 percent of cancers," said Dr. Stefanie Zalasin, a breast imaging specialist who reviewed the new findings. "Reassuring a patient that the overwhelming majority of mammograms and even biopsies are normal can ... Read more

Is It Parkinson's or Something Else? Blood Test Might Tell

Posted 12 days ago by Drugs.com

WEDNESDAY, Feb. 8, 2017 – Measuring a particular blood protein might help doctors easily distinguish Parkinson's disease from some similar disorders, a new study suggests. The potential blood test is "not ready for prime time," Parkinson's disease experts said. But, it marks progress in the quest for an objective way to diagnose Parkinson's and similar conditions known as atypical parkinsonian disorders, they noted. Parkinson's disease is a movement disorder that affects nearly 1 million people in the United States alone, according to the Parkinson's Disease Foundation. The root cause is unclear, but as the disease progresses, the brain loses cells that produce dopamine – a chemical that regulates movement. As a result, people suffer symptoms such as tremors, stiff limbs, and balance and coordination problems that gradually worsen over time. Right now, there is no blood test, brain ... Read more

Calcium Buildup in Young Arteries May Signal Heart Attack Risk

Posted 12 days ago by Drugs.com

WEDNESDAY, Feb. 8, 2017 – Young adults with any amount of calcified plaque in their arteries are already at risk of a heart attack, a new study finds. Among those 32 to 46 years old, even a little calcified plaque – called atherosclerosis, or hardening of the arteries – can boost the odds for fatal or nonfatal heart disease fivefold over the next 12 years, researchers found. "Heart disease really begins in adolescence and early adulthood," said lead researcher Dr. Jeffrey Carr. Carr is a professor of radiology, biomedical informatics and cardiovascular medicine at Vanderbilt University in Nashville, Tenn. For the study, CT scans, which can detect these potentially deadly blockages, were performed on more than 3,000 participants whose average age was 40. Just a small amount of plaque increased the risk of heart attack over the next decade by 10 percent, regardless of other risk ... Read more

Astronaut Twins Give Clues to Health Hazards of Spaceflight

Posted 18 days ago by Drugs.com

THURSDAY, Feb. 2, 2017 – Long-term space flight appears to trigger a number of genetic and biological changes in astronauts, according to preliminary results from a NASA study. Researchers compared astronaut Scott Kelly, who returned home last March after nearly a year aboard the International Space Station, and his identical twin Mark, a retired astronaut. Mark remained on Earth during that time. "Ten researchers are sharing biological samples taken from each twin before, during and after Scott's mission," according to a NASA news release. The goal of the NASA Twins Study is to learn more about how extended time in space affects the body. According to the report, Scott had altered levels of lipids (an indication of inflammation), and the telomeres on the ends of chromosomes in his white blood cells increased in length while he was in space. However, the telomeres started to shorten ... Read more

Breast Density May Be Leading Indicator of Cancer Risk

Posted 18 days ago by Drugs.com

THURSDAY, Feb. 2, 2017 – Women whose breasts are predominantly made up of more dense, glandular tissue face higher odds for breast cancer, a new study finds. The researchers added that, based on their study of 200,000 women, breast density may be the most important gauge of breast cancer risk, eclipsing family history of the disease and other risk factors. "The most significant finding in this study is the impact of breast density on development of breast cancer in the population," said study senior author Dr. Karla Kerlikowske. She is a researcher in the department of epidemiology and biostatistics at the University of California, San Francisco (UCSF). Still, not everyone is convinced that breast tissue density is the preeminent risk factor for breast cancer. Dr. Kristin Byrne is chief of breast imaging at Lenox Hill Hospital in New York City. She believes that the numbers in the ... Read more

Gene Discoveries Offer New Height Insights

Posted 19 days ago by Drugs.com

WEDNESDAY, Feb. 1, 2017 – Dozens of newly identified gene variants may have a major influence on height, British researchers say. "The new genetic variants we found are rare in the population but their large effects on human height have revealed important new insights into human skeletal growth," said Panos Deloukas, senior co-lead author of a new report on the genes. He's a professor at Queen Mary University of London. The identified genes will be helpful in predicting a person's risk of developing certain growth disorders, Deloukas said in a university news release. Hundreds of gene variants that affect height by less than 1 millimeter had already been pinpointed. But, the 83 newly identified gene variants can result in differences of up to 2 centimeters – about three-quarters of an inch. That's more than 10 times the average impact of the previously known variants, the researchers ... Read more

Pediatricians Say No to Wearable Smartphone Baby Monitors

Posted 24 Jan 2017 by Drugs.com

TUESDAY, Jan. 24, 2017 – Parents should think twice before buying "smart" clothing with vital signs monitors to keep tabs on their baby's health, pediatricians recommend. A new class of home baby monitor has come to the market. Electronic sensors attached to socks, onesies, buttons and such continually check "vitals" like breathing, pulse rate and oxygen levels. They notify parents of any abnormalities via smartphone. But repeated false alarms from the monitors jangle parents' nerves and lead to unnecessary tests performed on babies, said Dr. Christopher Bonafide. Bonafide is a doctor with the Children's Hospital of Philadelphia. He's also lead author of an editorial in the Jan. 24 issue of the Journal of the American Medical Association (JAMA). These baby vital signs monitors have not been approved by the U.S. Food and Drug Administration, and there's no evidence the devices prevent ... Read more

'Stress Ball' in Your Brain May Be Key to Heart Risks

Posted 12 Jan 2017 by Drugs.com

WEDNESDAY, Jan. 11, 2017 – Doctors have long known that a stressed life does no favors for the heart, and new research may help unravel why that's so. A Harvard team says heightened activity in a key part of the brain may explain why stress boosts people's odds for heart disease and stroke. The finding "raises the possibility that reducing stress could produce benefits that extend beyond an improved sense of psychological well-being," said study lead author Dr. Ahmed Tawakol, who co-directs the cardiac imaging program at Massachusetts General Hospital in Boston. One neurologist agreed that the research could have real value for patients. "This study provides information that can help us better understand the mechanisms in which the body and the brain affect each other," said Dr. Jeffrey Borenstein. He is president of the Brain & Behavior Foundation in New York City. "A better ... Read more

Obamacare Boosts Breast Cancer Screening, Study Finds

Posted 9 Jan 2017 by Drugs.com

MONDAY, Jan. 9, 2017 – Americans with lower levels of income are less likely to get recommended cancer screenings, but legislation waiving out-of-pocket costs appears to narrow the prevention gap – for mammograms, at least. That's the conclusion of researchers who studied a provision of the Affordable Care Act (ACA), also known as Obamacare, allowing people to obtain certain preventive health services free of charge. The study authors wanted to know: Did the ACA make a difference in Medicare beneficiaries' use of mammograms and colonoscopies to detect breast cancer and colon cancer, respectively? After Obamacare waived out-of-pocket expenses for cancer screenings, disparities between the wealthiest and poorest women in rates of screening mammography closed a bit, the study found. What's more, mammography rates increased by about 20 percent, on average, across all levels of income and ... Read more

Minority Women Less Likely to Get Breast Cancer Screening

Posted 16 Dec 2016 by Drugs.com

FRIDAY, Dec. 16, 2016 – Black and Hispanic women are less likely than white women to be screened for breast cancer, a large review finds. Screening rates for Asian/Pacific Islander and white women were similar, the research showed. The analysis of 39 studies including 6 million women was published Dec. 16 in the Journal of the American College of Radiology. "Not only do black and Hispanic women get screened less than white women, but disparities also persist in two age groups: women who are 40 to 65 years old, and 65 and older," study author Dr. Ahmed Ahmed said in a journal news release. "These findings are important; it's evident that more work needs to be done to ensure that all eligible women have access to this preventive screening tool," added Ahmed. He's a postdoctoral fellow researcher at the Mayo Clinic in Rochester, Minn. A great deal of effort has gone into finding racially ... Read more

MRI Helps Assess Fetal Brain Abnormalities: Study

Posted 15 Dec 2016 by Drugs.com

THURSDAY, Dec. 15, 2016 – A follow-up MRI scan after a mid-pregnancy ultrasound could help improve diagnosis of a possible fetal brain abnormality, a new British study reports. Women selected for this study had undergone an ultrasound at 18 to 21 weeks of pregnancy that detected a potential brain abnormality in the fetus. The extra information provided by the follow-up MRI helped doctors give a more accurate diagnosis and advice, according to the study authors. The study was published Dec. 14 in The Lancet. "Adding an MRI scan when a problem is detected provides additional information to support parents making decisions about their pregnancy," said lead author Paul Griffiths. He's a professor of radiology at the University of Sheffield. "Based on our findings we propose that an MRI scan should be given in any pregnancy where the fetus may have a suspected brain abnormality," Griffiths ... Read more

Never Too Old for a Mammogram?

Posted 28 Nov 2016 by Drugs.com

MONDAY, Nov. 28, 2016 – Women who think they're too old to worry about mammograms may want to reconsider the age at which their breast cancer screening years are behind them, a new study suggests. Based on an analysis of nearly 7 million mammograms over a seven-year period, "the benefit continues with increasing age up until 90," said study author Dr. Cindy Lee. She is an assistant professor in residence at the University of California, San Francisco. The question of when to stop having mammograms has been widely debated. In 2009, the U.S. Preventive Services Task Force issued new guidelines, saying there wasn't enough evidence to assess the balance of benefits and harms of screening mammography in women aged 75 and older. Lee and her colleagues looked at patient age, mammogram results, recall rates for more testing, biopsy referrals and biopsy results. The investigators also looked at ... Read more

Little Gains in Efforts to Boost Outpatient Care

Posted 17 Oct 2016 by Drugs.com

MONDAY, Oct. 17, 2016 – Efforts to improve the quality of care in the United States have had little impact on many aspects of outpatient care, a new, sweeping analysis shows. The researchers examined the quality of office-based care – meaning visits to physicians, physician assistants and nurse practitioners – between 2002 and 2013. Ongoing deficits in care "pose serious hazards to the health of the American public," the study authors concluded. One in four eligible Americans, for example, failed to receive recommended cancer screening. "That didn't change at all over 10 years and, in fact, got worse in places like mammography and cervical cancer screening," said study author Dr. David Levine. Levine is an internist and research fellow at Brigham & Women's Hospital and Harvard Medical School in Boston. Levine and his team also identified wasteful spending and possible harm due to ...

Scientists Launch Project to Map Every Cell in Human Body

Posted 14 Oct 2016 by Drugs.com

FRIDAY, Oct. 14, 2016 – A project to describe every cell in the human body would have been unrealistic just a few years ago. But international scientists meeting in London Friday said they believe this vast undertaking is now within reach. Once completed, the "Human Cell Atlas" could revolutionize how diseases are diagnosed and treated, according to the Wellcome Trust Sanger Institute, one of the meeting organizers. As ambitious in scope as the Human Genome Project – which cataloged the first full human DNA sequence – the Human Cell Atlas aims to chart the types and properties of all human cells to build a reference map of the human body, according to researchers involved in the project. "The cell is the key to understanding the biology of health and disease, but we are currently limited in our understanding of how cells differ across each organ, or even how many cell types there are ...
