For older adults, being unable to identify scents is a strong predictor of death within five years, according to a study published Oct. 1 in the journal PLOS ONE. Thirty-nine percent of study subjects who failed a simple smelling test died during that period, compared to 19 percent of those with moderate smell loss and just 10 percent of those with a healthy sense of smell.

Scientists find that essential fatty acid found in vegetable oils does not promote inflammation in humans
COLUMBIA, Mo. — A typical American consumes approximately 3 or more tablespoons of vegetable oil each day. Vegetable oils, like those from soy, corn and canola, are a significant source of calories and are rich in linoleic acid (LA), which is an essential nutrient. Since the 1970s, researchers have known that LA helps reduce blood cholesterol levels, and for decades, scientists have known that consuming LA can help lower the risk of heart disease. However, some experts have been claiming recently that Americans might be getting too much of a good thing. A new study from the University of Missouri contradicts that claim.
In the study, “Effect of Dietary Linoleic Acid on Markers of Inflammation in Healthy Persons: A Systematic Review of Randomized Controlled Trials,” researchers at the University of Missouri and the University of Illinois found that no link exists between vegetable oil consumption and circulating indicators of inflammation that are often associated with diseases such as heart disease, cancer, asthma and arthritis. While earlier animal studies have shown that a diet rich in LA can promote inflammation, MU animal sciences researcher Kevin Fritsche says that humans respond to LA differently. (more…)
*PhD candidate explores their interconnection*
Like any 28 year old, Arif Jetha, a fourth-year PhD candidate at the University of Toronto’s Dalla Lana School of Public Health, is worrying about his future. Once he completes his PhD, should he remain at home with his parents and pursue post-doctoral work or move on to full-time employment and begin establishing his career?
Then, he thinks about the participants in his Young Adult, Health and Employment Study (YHES) ) and realizes his own challenges pale in comparison to theirs. They are 18- to 30-year-olds who live with disabling health conditions such as lupus, juvenile arthritis and spinal cord injuries, and the transition to adulthood and employment is often exacerbated by their health status.

*UA scientists have teamed up to study the relationship between arsenic in human toenails and arsenic concentration in drinking water. Exposure to arsenic is associated with several chronic diseases ranging from dermatitis to various cancers.*
Scientists from the University of Arizona specializing in environmental health sciences and pharmacology and toxicology have teamed up with the help of a seed grant to study the relationship between arsenic in human toenails and arsenic concentration in drinking water.
Arsenic exposure in Arizona is a concern because of naturally occurring contamination of groundwater, said Miranda Loh, assistant professor of environmental health sciences at the UA Mel and Enid Zuckerman College of Public Health. (more…)
GAINESVILLE, Fla. — Skipping doses of medicine or taking it at the wrong times can worsen a patient’s condition and lead to costly complications — even organ rejection in patients who have undergone a kidney transplant.
A consortium of researchers in the United States and Canada, including at the University of Florida, has received a $2.5 million grant from the National Institutes of Health to test techniques that may increase medication adherence in perhaps the most challenging population of patients:teenagers.

*Intervention focuses on couples in which one partner is HIV-positive*
Intervention programs that promote healthier eating, increased physical activity and cancer screenings may be beneficial for African American couples that are at high risk for chronic diseases and that include one partner who is HIV-positive, according to new research.
With such inverventions, each partner appears to draw encouragement from the other to monitor his or her own lifestyle and health, according to study co-author Gail Wyatt, a professor of psychiatry and biobehavioral sciences at the Semel Institute for Neuroscience and Human Behavior at UCLA and an associate director of the UCLA AIDS Institute.

Less than seven hours of sleep each night is leading to a host of sleep-related problems including drowsy driving and difficulty concentrating at work, according to two new studies released on Thursday.
Roughly one-third of adults in 12 states reported getting less than seven hours of sleep each night with about the same number saying they’ve unintentionally dozed off during the day, according to one of the studies on sleep-related behavior from the Centers for Disease Control and Prevention.
