(Boston) - A new study shows that children whose families move frequently or live in overcrowded conditions are more likely to suffer from hunger and poor health than those in stable housing. The study was carried out by the Children's Sentinel Nutrition Assessment Program (C-SNAP) which has the largest clinical data base on poor children under age three in America. C-SNAP has been reporting on the impact of economic conditions and public policies on children's health since 1998.

CAMDEN – No matter the species, from flies to humans, we all start the same: a single-cell fertilized egg that embarks on an incredible journey. The specifics of this journey are being uncovered at Rutgers University–Camden, where a biologist is researching how from one cell a jumble of many are able to organize and communicate, allowing life to spring forth.
WILKES-BARRE, PA. – Patients treated with radiation prior to surgery for advanced rectal cancer have fewer instances of cancer recurrence and better overall survival rates, according to a recent Geisinger report.
The report examined a treatment called neoadjuvant therapy, which can reduce cancerous tumor size or limit the spread of cancer, before surgery to remove the tumor. Neoadjuvant therapy may include chemotherapy and/or radiation.
In the summer of 1968, Dave Kavanaugh set off on a hike that would change the course of his life. As a second-year medical student at the University of Colorado, he had joined a climbing club with a few members of the biophysics department, and the group had set their sights on Gray's Peak—the ninth highest mountain in Colorado. Kavanaugh, who has never been able to do anything slowly, scampered up to the top of the peak in record time and sat down to wait for the rest of the group. As he peeled an orange and gazed out at the surrounding terrain, a sudden movement caught his eye.
Researchers at the Burnham Institute for Medical Research (Burnham) have shown in both fruit flies and humans that genes involved in embryonic heart development are also integral to adult heart function. The study, led by Rolf Bodmer, Ph.D., was published in Proceedings of National Academy of Sciences.
A team led by Stanford researchers has developed a prototype blood scanner that can find cancer markers in the bloodstream in early stages of the disease, potentially allowing for earlier treatment and dramatically improved chances of survival.
A new paper released today by The George Institute for International Health is warning a cardiovascular disease based epidemic is gaining pace among many low- and middle-income countries (LMIC), exemplified at its worst in the world's largest populated countries – China and India. Preventive cardiovascular treatments that are widely available in high income countries are not yet widely accessed in LMIC, contributing to an escalating inequality in health status between rich and poor.
Researchers have discovered one potential mechanism by which briefly cutting off, then restoring, blood flow to arteries prior to a heart attack lessens the damage caused, according to a study published today in the journal Cardiovascular Research. The new mechanism points to how future drugs could provide protection ahead of heart attacks and strokes for those at highest risk. In the nearer term, the work may help to prevent damage caused as U.S. heart surgeons temporarily cut off blood flow 450,000 times each year to perform coronary artery bypass graft surgeries.
LOS ANGELES, Calif. – Dec. 2, 2008 – Presbycusis, or age-related hearing loss, accounts for 30 percent of all hearing loss. So, why do some people lose their hearing as they get older but other people can still hear a pin drop?
The answer may be in a study released online in the journal Human Molecular Genetics. Advance access is available online at http://hmg.oxfordjournals.org/papbyrecent.dtl.
CHICAGO – Including a patient's photo with imaging exam results may enable a more meticulous reading from the radiologist interpreting the images, as well as a more personal and empathetic approach, according to a study presented today at the annual meeting of the Radiological Society of North America (RSNA).
"Our study emphasizes approaching the patient as a human being and not as an anonymous case study," said lead author Yehonatan N. Turner, M.D., radiology resident at Shaare Zedek Medical Center in Jerusalem, Israel.
CHICAGO – New research reveals that computed tomography (CT) colonography, also known as virtual colonoscopy, has the potential to screen for two diseases at once—colorectal cancer and osteoporosis, both of which commonly affect adults over age 50. Results of the study will be presented today at the annual meeting of the Radiological Society of North America (RSNA).
CHICAGO – A study has found that positron emission mammography (PEM), a new technique for imaging the breast, is not affected by either breast density or a woman's hormonal status, two factors that limit the effectiveness of standard mammography and MRI at detecting cancer. Results will be presented today at the annual meeting of the Radiological Society of North America (RSNA).
Vienna, 2 December 2008 - The International Atomic Energy Agency (IAEA) today called for increased investment in a plant breeding technique that could bolster efforts aimed at pulling millions of people out of the hunger trap.
IAEA scientists use radiation to produce improved high-yielding plants that adapt to harsh climate conditions such as drought or flood, or that are resistant to certain diseases and insect pests. Called mutation induction, the technique is safe, proven and cost-effective. It has been in use since the 1920s.
In a new analysis of tissue biomarkers expressed in ovarian cancer samples, published by PLoS Medicine, David Huntsman and his colleagues from Vancouver General Hospital suggest that substantial differences exist between ovarian cancer subtypes which should be reflected in patient management. Although ovarian cancer is not the most common gynecologic cancer in women, the disease contributes a substantial burden of mortality in part because symptoms are nonspecific and the disease presents late in its course.
An article in this week's PLoS Medicine describes the African AIDS Vaccine Programme (AAVP), which was established in 2000. The AAVP is a network of African HIV vaccine stakeholders, led by Africans across the continent, with a vision of "an AIDS-free Africa through an effective vaccine."
