Increased risk of stroke in people with cognitive impairment

2014-08-25
(Press-News.org) People with cognitive impairment are significantly more likely to have a stroke, with a 39% increased risk, than people with normal cognitive function, according to a new study published in CMAJ (Canadian Medical Association Journal).

"Given the projected substantial rise in the number of older people around the world, prevalence rates of cognitive impairment and stroke are expected to soar over the next several decades, especially in high-income countries," writes Dr. Bruce Ovbiagele, Chair of the Department of Neurology, Medical University of South Carolina, Charleston, South Carolina, with coauthors.

Cognitive impairment and stroke are major contributors to disability, and stroke is the second leading cause of death world-wide. Although stroke is linked to the development and worsening of cognitive impairment, it is not known whether the reverse is true. Previous studies that have looked at the link between cognitive impairment and subsequent stroke have been inconsistent in their findings.

The study in CMAJ, by researchers in the United States, Taiwan and South Korea, analyzed data from 18 studies of 121 879 people with cognitive impairment, of whom 7799 later had strokes. Most of the included studies were conducted in North America or Europe.

The researchers observed a significantly higher rate of stroke in people with cognitive impairment than in people with normal cognitive function.

"We found that the risk of future stroke was 39% higher among patients with cognitive impairment at baseline than among those with normal cognitive function at baseline," write the authors. "This risk increased to 64% when a broadly adopted definition of cognitive impairment was used."

Blockage of blood vessels in the brain (brain infarcts), atherosclerosis, inflammation and other vascular conditions are associated with a higher risk of stroke and cognitive impairment and may contribute to the increased risk.

"Cognitive impairment should be more broadly recognized as a possible early clinical manifestation of cerebral infarction, so that timely management of vascular risk factors can be instituted to potentially prevent future stroke events and to avoid further deterioration of cognitive health," conclude the authors.

Knee surgery shows no benefit for people with mild osteoarthritis

2014-08-25
A new study indicates that there is no apparent benefit to arthroscopic knee surgery for age-related tears of the meniscus in comparison with nonsurgical or sham treatments. The study, published in CMAJ (Canadian Medical Association Journal), provides evidence that middle-aged or older patients with mild or no osteoarthritis of the knee may not benefit from the procedure. As people age, the meniscus in the knee thins and becomes less flexible and more susceptible to tearing. When the meniscus tears, it can cause pain and mechanical symptoms. Arthroscopic knee surgery ...

Knee surgery not needed for mild osteoarthritis: Study

2014-08-25
Their study, published in the Canadian Medical Association Journal (CMAJ) today, says middle-aged or older patients with mild or no osteoarthritis of the knee may not benefit from the procedure of arthroscopic knee surgery. Each year more than four million such keyhole surgeries are performed worldwide for degenerative meniscus tears. Doctors need to be carefully weighing the costs and benefits when deciding who should undergo such surgery, says Dr. Moin Khan, principal investigator for the study and research fellow in orthopedic surgery in the Michael G. DeGroote School ...

Yellow pigment in eye may aid vision through haze, suggests Optometry and Vision Science

2014-08-25
August 25, 2014 – Individuals with greater amounts of yellow pigment in the eye may be better able to see distant objects in hazy conditions, suggests a study in the September issue of Optometry and Vision Science, official journal of the American Academy of Optometry. The journal is published by Lippincott Williams & Wilkins, a part of Wolters Kluwer Health. Increased macular pigment (MP) may help in filtering out "blue haze," thus making distant objects more visible, according to the experimental study by Laura M. Fletcher, MS, and colleagues of University of Georgia, ...

New research: Parents of anxious children can avoid the 'protection trap'

New research: Parents of anxious children can avoid the protection trap
2014-08-25
Tempe, Ariz. (Aug. 25, 2014) - Parents naturally comfort their children when they are scared, but new research shows that some reactions may actually reinforce their children's feelings of anxiety. A new Arizona State University study shows that parents whose children suffer from anxiety often fall into the "protection trap" that may influence their child's behavior. The paper, "Variations in the Influence of Parental Socialization of Anxiety among Clinic Referred Children," was published in the journal, "Child Psychiatry and Human Development," by ASU graduate student ...

Happy Camper and July Fire Complexes in California

Happy Camper and July Fire Complexes in California
2014-08-25
The Happy Camp Complex of fires began as a lightning strike on August 12, 2014. Currently the fire has consumed 22,670 acres and is 20% contained. There are close to 2,000 personnel working on this fire at present. It consists of many small fires and a number of large ones. Most of the small fires have been contained and only account for about 100 acres. An inversion layer settled over the fire area throughout the morning and early afternoon on August 24, keeping fire activity moderate. As the inversion lifted in the afternoon, fire activity continued to the south. ...

Racial and ethnic stereotypes may contribute to obesity among minorities

2014-08-25
Many Americans need extraordinary willpower to avoid becoming obese – or to slim down if they already weigh too much. For members of minority groups, maintaining a healthy weight can be that much harder according to new research led by Luis Rivera, an experimental social psychologist at Rutgers University-Newark. Rivera says it is common for minorities in the United States to endure negative stereotypes, pervasive messages that suggest those groups are inferior, and that these attitudes can prevent people from doing what is needed to care for their health. "When you ...

Illinois scientists work with World Health Organization to fortify condiments, seasonings

2014-08-25
URBANA, Ill. – Two University of Illinois scientists are contributing to World Health Organization (WHO) efforts to fortify condiments and seasonings for use in countries with widespread micronutrient deficiencies. "In some countries where these deficiencies are widespread, there is consistent use—almost a daily dose—of certain condiments and seasonings, such as soy sauce in Southeast Asia, at all socioeconomic levels, and there's a real opportunity to correct deficiencies by fortifying these food items," said Luis A. Mejia, a U of I adjunct professor in food science ...

Organic vs. paid advertising? Inside the mind of an online browser

2014-08-25
NEW YORK—The keyword term a consumer uses in their search engine query can predict the likelihood that they will click on an organic or paid advertisement. That's according to new research by Columbia Business School that takes a unique look at a consumer's behavior between the keyword search and the point-of-click. The new information may give marketers the edge in converting even more consumer clicks on their sites. The research, "Consumer Click Behavior at a Search Engine: The Role of Keyword Popularity," published in this month's Journal of Marketing Research gives ...

Former Hurricane Lowell finally fades away

Former Hurricane Lowell finally fades away
2014-08-25
Satellite data showed that Lowell had ceased its life as a tropical cyclone over the past weekend. By Saturday, August 23 at 11 p.m. EDT, the once mighty and huge Tropical Storm Lowell degenerated into a remnant low pressure area. At that time, the center of post-tropical cyclone Lowell was located near latitude 24.7 north and longitude 127.4 west. That's about 1,110 miles (1,790 km) west of the southern tip of Baja California, Mexico. The post-tropical cyclone was moving toward the northwest near 8 mph (13 kph) and maximum sustained winds decreased to 25 mph (55 kph). NOAA's ...

NASA sees Marie become a major hurricane, causing dangerous surf
2014-08-25
The National Hurricane Center expected Marie to become a major hurricane (Category 3 or higher on the Saffir-Simpson Hurricane Wind Scale) and it did. On August 24, when NASA's Aqua satellite passed overhead, Marie reached Category 4 hurricane status and maintained strength on August 25. Marie continues to cause dangerous surf along the west coast of Mexico. The MODIS instrument (or Moderate Resolution Imaging Spectroradiometer) aboard NASA's Aqua satellite took a visible picture of Hurricane Marie as it reached Category 4 hurricane status off the west coast of Mexico ...
