Cleveland Clinic Children's Hospital research suggests transmission of respiratory viruses in utero
Study offers understanding of asthma development
2013-04-19
(Press-News.org) The most common cause of lower respiratory tract infections in infants and young children, respiratory syncytial virus (RSV), can be transferred during pregnancy to an unborn baby, according to Cleveland Clinic Children's Hospital research published online this week in the journal PLOS ONE.
In animal models, the study shows that RSV is able to spread across the placenta from the respiratory tract of the mother to the fetus, and is present in the lungs after birth, throughout development and into adulthood. RSV is considered the primary cause of infant pneumonia and has been implicated in the development of asthma.
"Epidemiologic evidence suggests that early-life RSV infection predisposes children to recurrent wheezing and asthma," said Giovanni Piedimonte, M.D., the study's lead author and Chairman of Cleveland Clinic Children's Hospital and the Pediatric Institute. "This study challenges the current paradigm that RSV infection is acquired only after birth and shifts attention to prenatal effects of the virus, which may result in more severe and lasting consequences by interfering with an unborn baby's critical developmental processes."
Research was completed in an animal model, in which rats were inoculated with RSV during midterm pregnancy. Of those infected, RSV was found in 30 percent of fetuses, as well as in the lungs of 40 percent of newborns and 25 percent of those that reached adulthood.
Dr. Piedimonte has been the principal investigator or co-investigator of more than 30 research projects, and has authored and co-authored more than 250 journal articles, book chapters, monographs, editorials and abstracts. He holds 17 international patents and is frequently invited to speak nationally and internationally.

Adding "chemical shift" techniques to MRI can help differentiate clear cell renal cell carcinoma from other types of renal cell cancer, a new study shows. That differentiation can help physicians better determine treatment for these patients.
The study, conducted at Massachusetts General Hospital in Boston, included 156 patients with proven renal cell cancer. Clear cell renal carcinoma contains microscopic areas of fat, which is not seen on conventional imaging, said Dr. Azadeh Elmi, lead author of the study. "Chemical shift MRI enables us to quantify even small amounts ...

2D plus 3D breast imaging increases cancer detection rates by 11%, and could be particularly useful in detecting cancer in women with dense breasts, a new study suggests.
Researchers at Yale University Smilow Cancer Hospital in New Haven, CT, reviewed the screening mammograms of 14,684 patients. Forty-two cancers were found in 8,769 patients who had only 2D imaging (a cancer detection rate of 4.8 per 1,000), said Dr. Jaime Geisel, a lead author of the study. Thirty-two cancers were found in the group that had 2D plus 3D (tomosynthesis) imaging, for a cancer detection ...

One view 3D breast screening (tomosynthesis) means less radiation dose and about five seconds less compression, but a study from Yale University, New Haven, CT, found that obtaining both views is necessary to help ensure that a cancer won't be missed.
There are practices in Europe that have reported performing only a single view, specifically the mediolateral oblique (MLO) view, said Dr. Noa Beck, the lead author of the study. Two views are standard in the U.S. for 3D breast screening; "we wanted to see if one view would be sufficient," she said. Seven breast imagers ...

One venous puncture, rather than two, is a safe and effective approach to intravascular ultrasound-guided inferior vena cava filter placement in critically-ill patients, a new study shows. Inferior vena cava filter placement is done to prevent or treat pulmonary emboli or deep venous thrombosis.
"The majority of institutions use a dual venous puncture technique, while we use a single venous puncture technique," said Dr. Andrew Gunn, of Massachusetts General Hospital in Boston. "We were interested to know if the different approaches affected technical success, clinical ...

Boston – More than three years after the United States Preventive Services Task Force (USPSTF) recommended against routine mammogram screening for women between the ages of 40 and 49, a study from Brigham and Women's Hospital (BWH) finds that mammogram rates in the United States have not declined in that age group, or any other. The study results are published in the April 19, 2013 online edition of the journal Cancer.
"If the USPSTF recommendations had been widely adopted, we would have expected to see a significant decline in mammography rates among women in their ...

Divorce rates in some parts of New York State have been on the rise recently, according to a report by YNN. Some experts believe the uptick may be related to New York's new no-fault divorce law, which was enacted in October 2010. The new law has streamlined the divorce process for New Yorkers who wish to part ways without formally assigning blame for the breakdown of the marriage.

Truck driving is not a nine-to-five job. It entails working into the very late or very early hours of the day on the road away from home. To help protect truckers from being overworked (and to increase the safety of other motorists) the government regulates how frequently truck drivers must stop and rest.
These regulations are called hours of service (HOS) rules. They are implemented to help ensure that truck drivers are ...
