Cyberstalking: Dealing with the cyberworld's dark side

WASHINGTON – People who are cyberstalked or harassed online experience higher levels of stress and trauma than people who are stalked or harassed in person, according to a presentation at the American Psychological Association's 119th Annual Convention.

"Increasingly, stalkers use modern technology to monitor and torment their victims, and one in four victims report some form of cyberstalking, such as threatening emails or instant messaging," said Elizabeth Carll, PhD, in a talk entitled, "Electronic Harassment and Cyberstalking: Intervention, Prevention and Public Policy."

Dieting - now with less willpower needed

WASHINGTON – Dieters may not need as much willpower as they think, if they make simple changes in their surroundings that can result in eating healthier without a second thought, said a consumer psychologist at the American Psychological Association's 119th Annual Convention.

"Our homes are filled with hidden eating traps," said Brian Wansink, PhD, who presented his findings and strategies for a healthier lifestyle in a plenary address entitled "Modifying the Food Environment: From Mindless Eating to Mindlessly Eating Better."

Friending the Virgin: What Rembrandt and Facebook have in common

Stereotype threat - if you're prejudiced against yourself, small interventions may help

WASHINGTON – Picture black and white students at an Ivy League college learning about black students who are a year or so ahead of them in that school. They're told that the older black students were anxious about fitting in and how they would be viewed in college when they first arrived. But as the older black students got more involved in campus life, they began to find the school rewarding, even exciting as their life course took shape.

US physician practices spend 4 times Canadian practices

NEW YORK (Aug. 4, 2011) -- Physicians in the United States spend nearly four times as much dealing with health insurers and payers compared with doctors in Canada. Most of the difference stems from the fact that Canadian physicians deal with a single payer, in contrast to the multiple payers in the United States.

These findings are published in the August issue of the journal Health Affairs -- the result of a research collaboration among Weill Cornell Medical College, Cornell University–Ithaca, the University of Toronto, and the Medical Group Management Association.

Wireless network in hospital monitors vital signs

A clinical warning system that uses wireless sensors to track the vital signs of at-risk patients is undergoing a feasibility study at Barnes-Jewish Hospital in St. Louis.

When the full system is operational sensors will take blood oxygenation and heart-rate readings from at-risk patients once or twice a minute. The data will be transmitted to a base station, where they will be combined with other data in the patient's electronic medical record, such as lab test results.

Poorly controlled asthma costly

Poorly controlled asthma more than doubles healthcare costs associated with the disease and threatens educational achievement through a dramatic increase in school absence, according to researchers at National Jewish Health. The research team reported in the August 2011 issue of The Archives of Allergy, Asthma & Immunology that children with "very poorly controlled" asthma missed an average of 18 days of school each year, compared to 2 or less for other asthma patients.

Positive relationships at work lead to long-term health benefits

Tel Aviv — Companies like Google and Zappos.com are famous for their "work hard, play hard" attitudes and friendly work environments, but are their employees healthier too? According to a Tel Aviv University researcher, a positive relationship with your co-workers has long-term health benefits.

Use of a retroflexion technique during colonoscopy in the right side of the colon improves polyp detection

OAK BROOK, Ill. – August 4, 2011 – A new study from researchers in Indiana reports that use of a retroflexion technique in the right side of the colon during colonoscopy is safe and results in the detection of additional adenomatous (precancerous) polyps in approximately four percent of patients. This result is comparable to that expected from a second colonoscopy in the forward view. The study appears in the August issue of GIE: Gastrointestinal Endoscopy, the monthly peer-reviewed scientific journal of the American Society for Gastrointestinal Endoscopy (ASGE).

High-risk stroke patients more likely to get follow-up care after motivational talk

ANN ARBOR, Mich. — Even though many Americans learn through community health screenings that they are at high risk for having a stroke, they rarely follow-up with their doctor for care.

But a new University of Michigan study shows high-risk stroke patients are twice as likely to get follow-up care from a primary care doctor if they receive a pep talk over the telephone.

Small and local businesses pack a powerful economic punch

Thinking small and local, not big and global, may help communities ignite long-term economic growth, according to Penn State economists. Small, locally owned businesses and startups tend to generate higher incomes for people in a community than big, nonlocal firms, which can actually depress local economies, said Stephan Goetz, professor of agricultural and regional economics.

Don't forest me in - 6 million years of African savannas and human evolution

Scientists using chemical isotopes in ancient soil to measure prehistoric tree cover--in effect, shade--have found that grassy, tree-dotted savannas prevailed at most East African sites where human ancestors and their ape relatives evolved during the past six million years.

"We've been able to quantify how much shade was available in the geological past," says University of Utah geochemist Thure Cerling, lead author of a paper titled "Woody cover and hominin environments in the past 6 million years" on the results in this week's issue of the journal Nature.

Disappearance of genetic material allows tumor cells to grow

Malignant Sézary syndrome is characterized by the reproduction of a special type of white blood cells in the skin of male and female patients. In contrast to most other skin lymphomas, patients with Sézary syndrome manifest not only skin contamination but also contamination of blood and lymph nodes by degenerate T cells even at the onset of the disease.

Compression stockings may reduce OSA in some patients

Wearing compression stockings may be a simple low-tech way to improve obstructive sleep apnea in patients with chronic venous insufficiency, according to French researchers.

"We found that in patients with chronic venous insufficiency, compression stockings reduced daytime fluid accumulation in the legs, which in turn reduced the amount of fluid flowing into the neck at night, thereby reducing the number of apneas and hypopnea by more than a third," said Stefania Redolfi, MD, of the University of Brescia in Italy, who led the research.

Text message reminders improve healthcare practice in rural Africa, study finds

New research funded by the Wellcome Trust has shown that sending text message reminders to healthcare workers in rural Africa can improve the implementation of national guidelines for treating malaria. The intervention led to more patients receiving accurate antimalarial treatment.

The study, published today in The Lancet, was carried out by researchers at the Kenya Medical Research Institute (KEMRI)-Wellcome Trust Research Programme in Nairobi.
