Young adult, teen cancer patients studied IRVINE, Calif. (UPI) -- Teens and young adults with cancer require targeted care that crosses the boundaries between pediatric and adult oncology, U.S. researchers suggest. Dr. Leonard S. Sender of University of California, Irvine, says pioneers in the still-developing field of adolescent and young adult oncology had a roundtable discussion that helped identify 15-to-39-year-old cancer patients as a distinct and relevant patient group. "Adolescent and young adult cancer presents the medical community with several unique problems. First, it requires true collaboration between pediatric and medical oncologists as the age range crosses both disciplines," Sender said in a statement. "Next, our adolescent and young adult cancer patients not only have cancer but are also often dealing with ongoing developmental and psychosocial issues at the same time; as such, we must be aware of how a cancer diagnosis interferes with their normal development." Several factors contributed to the growing recognition that adolescents and young adults are a distinct group of cancer patients who have not had the same improvements in overall survival as their younger and older peers, Sender said. The reasons for the differences have not been fully understood but many experts suspect multiple factors working independently or together. These include biological differences, treatment protocol or medical facility variances, lack of relevant clinical trials or access to care due to a lack of insurance or inadequate insurance.

Study: News consumers interested in facts COLUMBUS, Ohio (UPI) -- News reporting that doesn't attempt to resolve factual disputes in politics may have detrimental effects on readers, U.S. communications experts say. "There are consequences to journalism that just reports what each side says with no fact checking," study author Raymond Pingree, an assistant professor of communication at Ohio State University, says in a statement. "It makes readers feel like they can't figure out what the truth is. And I would speculate that this attitude may lead people to tune out politics entirely, or to be more accepting of dishonesty by politicians." Pingree conducted an experiment with 538 college students in which all were asked to read one of four versions of a fictional news story about a fictional healthcare bill under debate in the House of Representatives. The stories were nearly identical and set up two factual debates about the bill. In one, opponents of the bill claimed that its cost will be far higher than the estimated $200 million and in the other, opponents claimed that the bill is redundant with Medicaid and will create unnecessary bureaucracy. Other versions simply mentioned the dispute with no fact checking. The study, published in the Journal of Communication, found people who read the passive article -- lacking a resolution of contradictory assertions -- felt they were less able to find truth in politics, compared to those who read the article resolving who was correct in the debate. "It is noteworthy that just reading a single news story about a single topic can affect how people feel about their own ability to find truth in politics," Pingree says.

Pancreatitis not always linked to alcohol INDIANAPOLIS (UPI) -- Contrary to popular belief, not all cases of chronic pancreatitis are alcohol-induced, U.S. researchers said. Lead author Dr. Gregory A. Cote of Indiana University School of Medicine said patients with no identifiable cause for pancreatitis, as well as those with non-alcohol-related causes, represent an unexpectedly large subgroup, particularly among women. "One of the more remarkable observations is that in more than 50 percent of patients, alcohol was not considered as the causative factor of chronic pancreatitis," Cote said in a statement. "Future analyses will likely identify previously unrecognized genetic factors and/or interaction between genes and environmental factors as potential explanations of disease development. In the meantime, the era of dismissing all cases of chronic pancreatitis as alcohol-induced has undoubtedly come to a close." The researchers studied data from patients with chronic pancreatitis and controls enrolled in the North American Pancreatitis Study. The study, published in the journal Clinical Gastroenterology and Hepatology, found among the groups, 44.5 percent of patients had chronic pancreatitis due to alcohol consumption, 26.9 percent had non-alcohol related chronic pancreatitis and 28.6 percent had chronic pancreatitis of unknown cause.

Stem cells used for bone grafts FORT LAUDERDALE, Fla. (UPI) -- Surgeons are using new methods to get bone material, and even stem cells, right "off the shelf," a California foot and ankle surgeon says. Dr. Glenn M. Weinraub -- who led a discussion among surgeons on bone healing at the American College of Foot and Ankle Surgeons' annual scientific conference in Fort Lauderdale, Fla. -- says bone grafts are generally used for large open fractures with bone loss, broken bones that have not healed, bone tumors and reconstructive procedures. "Harvesting a patient's own bone has always been considered the gold standard, but nowadays I think that concept should be thought of as the historical standard," Weinraub, president of ACFAS, says in a statement. Grafts are helpful for patients who might not heal under normal conditions, such as smokers, diabetics, people who are obese or patients with nutritional deficits. However, surgeons can now use stem cells, which are self-renewing cells found throughout the body, to assist the bone in healing. "These cells have the potential to become almost any other cell in the body and can actually form bone," Weinraub says. Like bone graft material, stem cells can come from the patient or a lab, which harvests the cells from the bones of donors and makes billions of copies, Weinraub says.
