Study: Native Hawaiians at higher risk of hemorrhagic stroke at younger age

2011-02-16
(Press-News.org) ST. PAUL, Minn. – Native Hawaiians and Pacific Islanders may be at higher risk for hemorrhagic stroke at a younger age and more likely to have diabetes compared to other ethnicities, according to a study released today that will be presented at the American Academy of Neurology's 63rd Annual Meeting in Honolulu April 9 to April 16, 2011.

"Racial differences in stroke risk factors have been well-studied in Hispanic and African-American populations, but this is the first study to address people of Native Hawaiian ethnicity," said study author Kazuma Nakagawa, MD, with The Queen's Medical Center in Honolulu.

Data on 573 people hospitalized for intracerebral hemorrhage was taken from the "Get with the Guidelines-Stroke" database from The Queen's Medical Center over a period of six years. Of those, 18 percent were Native Hawaiian/Pacific Islanders, 63 percent were Asian, 16 percent were Caucasian, 0.2 percent were African-American and three percent were described as other.

On average, Native Hawaiians who experienced a hemorrhagic stroke were around the age of 55, more than 10 years younger than those from other racial groups which had a combined average age of 67 when a stroke occurred. More Native Hawaiians also had diabetes; 35 percent compared to other racial groups at 21 percent. There were no differences in gender or other cardiovascular risk factors between the groups.

"Knowing risk factors for certain populations is an important step toward recognizing, treating and preventing stroke. More research needs to be done to determine which factors are contributing to stroke at such a young age in Native Hawaiians," said Nakagawa.

### The study was supported by the Queen Emma Research Fund and the Hawaii Community Foundation.

The American Academy of Neurology, an association of more than 22,500 neurologists and neuroscience professionals, is dedicated to promoting the highest quality patient-centered neurologic care. A neurologist is a doctor with specialized training in diagnosing, treating and managing disorders of the brain and nervous system such as Alzheimer's disease, stroke, migraine, multiple sclerosis, brain injury, epilepsy and Parkinson's disease.

Alcohol's disruptive effects on sleep may be more pronounced among women

Contact: Ian Demsky idemsky@umich.edu 734-764-2220 University of Michigan Alcoholism: Clinical & Experimental Research Alcohol's disruptive effects on sleep may be more pronounced among women Researchers have known for decades that alcohol can initially deepen sleep during the early part of the night but then disrupt sleep during the latter part of the night; this is called a "rebound effect." A new study of the influence of gender and family history of alcoholism on sleep has found that intoxication can increase feelings of sleepiness while at the same time ...

Analysis of violent deaths of Iraqi civilians between 2003-2008

2011-02-16
A paper published in this week's issue of PLoS Medicine provides the most detailed assessment thus far of civilian deaths in the course of the recent Iraq war. Madelyn Hsiao-Rei Hicks from King's College London, UK and colleagues analyzed data from Iraq Body Count (IBC), a nongovernmental project that collates media reports of deaths of individual Iraqi civilians and cross-checks these reports with data from hospitals, morgues, nongovernmental organizations, and official figures. The authors studied 92,614 Iraqi civilian direct deaths from the IBC database that occurred ...

Intravaginal practices are associated with acquiring HIV infection

2011-02-16
Although there is no evidence to suggest a direct causal pathway, some intravaginal practices used by women in sub-Saharan Africa (such as washing the vagina with soap) may increase the acquisition of HIV infection and so should be avoided. Encouraging women to use less harmful intravaginal practices (for example, washing with water alone) should therefore be included in female-initiated HIV prevention research strategies in sub-Saharan Africa. These are the key findings from a study by Nicola Low, from the University of Bern, Bern, Switzerland, and colleagues and published ...

Ion-exchange water softeners do not improve eczema in children

2011-02-16
Water softeners provide no additional clinical benefit to usual care in children with eczema, so the use of ion-exchange water softeners for the treatment of moderate to severe eczema in children should not be recommended. However, it is up to each family to decide whether or not the wider benefits of installing a water softener in their home are sufficient to consider buying one. These are the findings of a study by Kim Thomas from the University of Nottingham, Nottingham, UK, and colleagues and published in this week's PLoS Medicine. The authors conducted their randomised ...

Atomic model of tropomyosin bound to actin

2011-02-16
New research sheds light on the interaction between the semi-flexible protein tropomyosin and actin thin filaments. The study, published by Cell Press on February 15th in the Biophysical Journal, provides the first detailed atomic model of tropomyosin bound to actin and significantly advances the understanding of the dynamic relationship between these key cellular proteins. Tropomyosin is a long protein that associates with actin, a highly conserved thin filament protein found in organisms from yeast to humans. Actin, a major part of the cell's cytoskeleton, drives shape ...

Jefferson researchers provide genetic evidence that antioxidants can help treat cancer

2011-02-16
PHILADELPHIA—Researchers from Jefferson's Kimmel Cancer Center have genetic evidence suggesting the antioxidant drugs currently used to treat lung disease, malaria and even the common cold can also help prevent and treat cancers because they fight against mitochondrial oxidative stress—a culprit in driving tumor growth. For the first time, the researchers show that loss of the tumor suppressor protein Caveolin-1 (Cav-1) induces mitochondrial oxidative stress in the stromal micro-environment, a process that fuels cancer cells in most common types of breast cancer. "Now ...
