Timely depression diagnosis critical to maintain health of elderly

MU researchers find non-mood changes related to depression in elderly

2010-11-10

(Press-News.org) COLUMBIA, Mo. – Depression affects approximately 30 to 40 percent of nursing home residents, but it often goes unrecognized, according to American Geriatrics Society, which can lead to lower quality of life or even suicide. Now, researchers at the University of Missouri have found a series of indicators, other than changes in mood that are associated with the development of depression in nursing home residents.

"Prompt diagnosis and treatment of depression is essential to improve the quality of life for nursing home residents," said Lorraine Phillips, assistant professor in the Sinclair School of Nursing. "Many elderly people develop certain clinical characteristics at the same time they develop depression. Understanding these changes is essential to quickly and accurately diagnosing depression in nursing home residents."

Changes in characteristics that Phillips found to be associated with the development of depression include increased verbal aggression, urinary incontinence, increased pain, weight loss, changes in care needs, reduced cognitive ability and decline in performance of daily living activities.

"Depression is currently diagnosed using several methods that emphasize mood symptoms including interviewing and self-reporting of depression symptoms," Phillips said. "However, since elderly depression may appear with non-mood symptoms, these characteristics identified in this study can help diagnose depression that may be overlooked by traditional screening methods."

Phillips found that residents with increased verbal aggression were 69 percent more likely to be diagnosed with depression than those who had not shown these changes. Decreases in activities of daily living, such as feeding or dressing one's self, also were associated with increased depression diagnosis. The research indicates that men and women in nursing homes are equally likely to develop depression. This contrasts with the overall population, where women are more likely than men to experience depression.

To study these changes, MU researchers analyzed data on more than 14,000 nursing home residents aged 65 and older who were not diagnosed with depression at the beginning of the study. Researchers analyzed changes in various clinical factors, other than mood changes, to discover which changes were associated with the development of depression during a three-month interval of time. The data was collected from the Missouri Minimum Data Set, a federally mandated process for clinical assessment of all residents in Medicare- or Medicaid-certified nursing homes.

INFORMATION:

Phillips worked with Marilyn Rantz, a professor in the MU Sinclair School of Nursing and chair of the MU Minimum Data Set and Quality Research Team, and Gregory Petroski, a research assistant professor and statistician in the Office of Medical Research. The study was published in the Journal of Gerontological Nursing.

Study shows young, unsupervised children most at risk for dog bites

2010-11-10

AURORA, Colo. (Nov. 9, 2010) – As dog bites become an increasingly major public health concern, a new study shows that unsupervised children are most at risk for bites, that the culprits are usually family pets and if they bite once, they will bite again with the second attack often more brutal than the first. The study, the largest of its kind, was done by Vikram Durairaj, MD, of the University of Colorado School of Medicine, who found that dogs usually target a child's face and eyes and most often it's a breed considered `good' with children, like a Labrador retriever. "People ...

Myth of a germ-free world: A closer look at antimicrobial products

2010-11-10

Killing microorganisms has become a national obsession. A pair of antimicrobial compounds known as triclosan and triclocarban are lately the weapons of choice in our war of attrition against the microbial world. Both chemicals are found in an array of personal care products like antimicrobial soaps, and triclosan also is formulated into everyday items ranging from plastics and toys to articles of clothing. But are these antimicrobial chemicals, as commonly used by people across the nation, really safe for human health and the environment? More pointedly, do they even ...

Overcoming the IVF baby blues

2010-11-10

Between 20 and 30 percent of women who undergo in vitro fertilization (IVF) procedures suffer from significant symptoms of depression. Many practitioners believe that the hormone therapy involved in IVF procedures is primarily responsible for this. But new research from Tel Aviv University shows that, while this is true, other factors are even more influential. According to Dr. Miki Bloch of Tel Aviv University's Sackler Faculty of Medicine and the Sourasky Medical Center in Tel Aviv, stress, pre-existing depression, and anxiety are more likely than hormone therapy ...

Improving soil for better lawns and gardens

U.S. Department of Agriculture (USDA) scientists in West Virginia are finding ways to improve soil on degraded land so it can be used for sports fields and other uses. Researchers with USDA's Agricultural Research Service (ARS) at the agency's Appalachian Farming Systems Research Center (AFSRC) in Beaver, W.Va., are developing constructed or replacement subsoils and topsoils to build better and less-costly sports fields, raingardens and lawns on former landfills, mine lands and other degraded land. ARS is USDA's principal intramural scientific research agency. The constructed ...

Sick at work and surfing the net? You're not alone -- or are you?

2010-11-10

ANN ARBOR, Mich.---Some scholars estimate that presenteeism, a relatively recent buzzword that applies to people who are less productive at work because of health issues, costs employers as much as three times the dollar amount as absenteeism in terms of lost productivity. But researchers at University of Michigan believe those numbers may be inaccurate. A new opinion paper suggests that the tools for measuring and quantifying hours of lost productivity and translating those hours to dollars are unreliable and don't capture the entire presenteeism picture, said Susan ...

NASA's Fermi telescope discovers giant structure in our galaxy

2010-11-10

WASHINGTON -- NASA's Fermi Gamma-ray Space Telescope has unveiled a previously unseen structure centered in the Milky Way. The feature spans 50,000 light-years and may be the remnant of an eruption from a supersized black hole at the center of our galaxy. "What we see are two gamma-ray-emitting bubbles that extend 25,000 light-years north and south of the galactic center," said Doug Finkbeiner, an astronomer at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass., who first recognized the feature. "We don't fully understand their nature or origin." The ...

Researchers discover important link between adrenal gland hormone and brain in hypertension

2010-11-10

DALLAS – Nov. 9, 2010 – A hormone already responsible for increasing blood pressure by prompting the kidneys to retain salt appears to moonlight as a major stimulator of the brain centers that control the vascular system and blood pressure. Researchers at UT Southwestern Medical Center studied patients who overproduce aldosterone to see whether the hormone had any effect on sympathetic nerve activity responsible for blood pressure increases. "Between 10 percent and 20 percent of patients with high blood pressure who are resistant to treatment have elevated aldosterone ...
