(Press-News.org) NEW YORK, January 23, 2012 – When it comes to taking prescribed medications for hypertension, a patient's self confidence could be as important as doctor's orders. A new study by researchers at NYU School of Medicine reveals that positive affirmation, when coupled with patient education, seems to help patients more effectively follow their prescribed medication regimen.
The study, funded by the National Heart, Lung, and Blood Institute, appears online ahead of print today in the Archives of Internal Medicine, one of the JAMA/Archives journals.
"As doctors, we're always trying to do the right thing for our patients and get them to do the right thing for themselves – change their habits, adopt healthier lifestyles," said lead author Gbenga O. Ogedegbe, MD, of the Center for Healthful Behavior Change (CHBC) at NYU School of Medicine. "Patients know what the doctors tell them they should do. Often however, knowledge of what to do and the consequences of not doing so are not sufficient. With this study, we were looking for a way to effectively increase motivation and improve patients' medication taking behavior, as hypertension is a serious problem in this country."
For the study, Ogedegbe and colleagues enrolled 256 hypertensive African-Americans and randomized them into two study groups. Patients in both groups received a hypertension self-management workbook, a behavioral contract that asked participants to make a commitment to taking their medications as prescribed, and bimonthly telephone calls to help the participants overcome barriers to medication compliance. Additionally, patients in the intervention group were given an extra chapter in their workbook that addressed the benefits of positive moments in overcoming obstacles to taking their blood pressure medications. They were also encouraged during their bimonthly calls to identify small things in their lives that invoke positive feelings and to incorporate those positive thoughts into their daily routines. As part of the intervention, these participants received unexpected small gifts mailed to them before each telephone call and were asked to remember their core values and proud moments in their lives whenever they encounter situations that make it difficult for them to take their medications.
Researchers followed the participants for one year and then compared medication adherence between the two groups for the study period.
They found that participants in the intervention group had 22 percent higher adherence rates than those in the control group, indicating that enhancing simple patient education with positive psychology can have a significant impact on adherence rates, particularly in hypertensive African-Americans.
"Other studies have shown that positive feelings can affect health behavior, but to our knowledge, no previous studies have looked at the effect of positive feelings on medication adherence," said co-investigator Joseph E. Ravenell, MD, also of the CHBC. "This is a relatively simple target that may have a huge impact and certainly a path we should pursue to combat cardiovascular disease. It's possible that, with future research, the findings could extend to a broader range of medical conditions, as well."
The study was conducted in African-Americans, who are disproportionately affected by hypertension compared to whites and suffer worse hypertension-related outcomes. Poor medication adherence may explain, to some extent, poor blood pressure control in hypertensive patients – especially African-Americans – which can lead to serious cardiovascular problems and death.
Hypertension – or high blood pressure – is one of the most serious known contributors of heart disease, the leading cause of death in the United States. One in three adults in the country has hypertension, according to the National Institutes of Health, which estimated that number to be more than 76 million people in 2008.
Dr. Ogedegbe is a clinical epidemiologist, hypertension specialist, and behavioral scientist with expertise in development, implementation and translation of evidence-based behavioral interventions targeted at cardiovascular risk reduction in minority populations into primary care practices and community-based settings. He and other researchers involved with the CHBC at the School of Medicine, are dedicated to translating research into clinical improvements in medicine by finding simple strategies that physicians and other individuals in healthcare can use in real world settings to improve patient health.

CHAMPAIGN, Ill. — Land and marine iguanas and giant tortoises living close to human settlements or tourist sites in the Galápagos islands are more likely to harbor antibiotic-resistant bacteria than those living in more remote or protected sites on the islands, researchers report in a new study.
Feces collected at several different sites from free-living reptiles harbored Escherichia coli bacteria that were resistant to ampicillin, doxycycline, tetracycline, and trimethoprin/sulfamethoxazole. Another bacterial species collected from the feces, Salmonella enterica, was ...
URBANA – Could preventing colon cancer be as simple as developing a taste for yerba mate tea? In a recent University of Illinois study, scientists showed that human colon cancer cells die when they are exposed to the approximate number of bioactive compounds present in one cup of this brew, which has long been consumed in South America for its medicinal properties.
"The caffeine derivatives in mate tea not only induced death in human colon cancer cells, they also reduced important markers of inflammation," said Elvira de Mejia, a U of I associate professor of food chemistry ...

CHICAGO (January 23, 2012) – A new study published online today in the Journal of the American College of Surgeons finds hospitals participating in a regional collaborative of the American College of Surgeon's National Surgical Quality Improvement Program (ACS NSQIP®), achieved substantial improvements in surgical outcomes, such as reducing the rates of acute renal failure and surgical site infections. The collaborative also saved $2,197,543 per 10,000 general and vascular surgery cases when comparing results from 2010 with results from 2009. ACS NSQIP is the leading nationally ...
INDIANAPOLIS — An Indiana University School of Medicine study has determined that a patient's socioeconomic status has more influence than race on physician diagnosis of whether a child's injury was accidental or caused by abuse.
When presented with scenarios that could possibly but not obviously indicate child abuse, 2,109 physicians from across the United States who participated in the study were most likely to suspect maltreatment rather than accident for white children from families with low socioeconomic status than for black children with low socioeconomic status ...

Troy, N.Y. – Graphene is the thinnest material known to science. The nanomaterial is so thin, in fact, water often doesn't even know it's there.
Engineering researchers at Rensselaer Polytechnic Institute and Rice University coated pieces of gold, copper, and silicon with a single layer of graphene, and then placed a drop of water on the coated surfaces. Surprisingly, the layer of graphene proved to have virtually no impact on the manner in which water spreads on the surfaces.
Results of the study were published Sunday in the journal Nature Materials. The findings ...
Chicago -- U.S. states that enacted unilateral divorce laws saw substantial increases in violent crime in the years following the reform, according to research in the Journal of Labor Economics. But the ill-effects of the new laws appear to be largely temporary.
The research found an average 9 percent increase in violent crime after a state enacted a unilateral divorce law, which allows one spouse to end a marriage without the consent of the other. The increase in crime was mainly confined to the first two decades after the reform and was mostly attributable to individuals ...

WASHINGTON, DC – A Georgetown University Medical Center professor says the voluntary action taken by two research teams to temporarily halt work involving the highly pathogenic avian influenza H5N1 is "laudable."
In the researchers' statement, published today by Science and Nature, the authors stated that they "recognize that we and the rest of the scientific community need to clearly explain the benefits of this important research and the measures taken to minimize its possible risks." The statement comes in the wake of a debate following the U.S. government's request ...
