(Press-News.org) MINNEAPOLIS – A new study suggests that Chinese people may be at higher risk for stroke than Caucasians. The research is published in the July 16, 2013, print issue of Neurology®, the medical journal of the American Academy of Neurology.
"While stroke is the second most-common cause of death worldwide, in China it is the leading cause of death and adult disability," said study author Chung-Fen Tsai, MD, with the University of Edinburgh in Scotland. "The global impact of stroke in the decades ahead is predicted to be greatest in middle income countries, including China. It is important to gain a better understanding of how stroke affects different populations as we try to reduce the burden of the disease worldwide."
For the analysis, researchers reviewed studies from 1990 onward that included first strokes in Chinese people in China and Taiwan. A total of 404,254 Chinese were included. The study included more than two million person-years and 3,935 strokes.
The researchers also identified 10 community-based studies among Caucasians including 1,885,067 people, more than 3.2 million person-years and 4,568 strokes.
Comparing the two groups, the research found a slightly higher overall risk of stroke in Chinese people than in Caucasians, with a range of 205 to 584 strokes per 100,000 Chinese people age 45 to 74, compared to 170 to 335 strokes per 100,000 Caucasian people the same age. Chinese also had a higher risk of intracerebral hemorrhage, a type of stroke due to bleeding into the brain from a ruptured blood vessel, compared to Caucasian people, or 33 percent of all strokes compared to 12 percent of all strokes in community-based studies. Chinese people had a lower average age of stroke onset of 66 to 70 years-old, compared to 72 to 76 years-old for Caucasians.

The vaccination programme against HPV infection began in 2008 in the UK, but only among girls, on the grounds that this would curb the spread of the infection to boys as well.
But, say the authors, from the Royal Liverpool University Hospital, Homerton University Hospital, and Chelsea and Westminster Hospital, gay men are more than 15 times as likely to develop genital cancer, particularly anal cancer, as a result of becoming infected with HPV, as are straight men.
While rates of anal cancers are higher among men who are also HIV positive - despite antiretroviral treatment ...
Massachusetts General Hospital (MGH) researchers have used vascular precursor cells derived from human induced pluripotent stem cells (iPSCs) to generate, in an animal model, functional blood vessels that lasted as long as nine months. In their report being published in PNAS Early Edition, the investigators describe using iPSCs – reprogrammed adult cells that have many of the characteristics of embryonic stem cells – from both healthy adults and from individuals with type 1 diabetes to generate blood vessels on the outer surface of the brain or under the skin of mice. ...
In children with fever but no other symptoms of illness, it is difficult to know whether a child has a viral infection that will resolve on its own or a potentially serious bacterial infection that requires antibiotics.
Now, researchers at Washington University School of Medicine in St. Louis report that they can distinguish between viral and bacterial infections in children with fever by profiling the activity of genes in a blood sample. In a small study, analyzing genes in white blood cells was more than 90 percent accurate, far better than the standard diagnostic test, ...
The risk of elevated blood pressure among children and adolescents rose 27 percent during a thirteen-year period, according to new research in the American Heart Association journal Hypertension.
Higher body mass, larger waistlines and eating excess sodium may be the reasons for the elevated blood pressure readings, researchers said.
High blood pressure is a risk factor for stroke, heart disease and kidney failure — accounting for about 350,000 preventable deaths a year in the United States.
"High blood pressure is dangerous in part because many people don't know they ...
Prosthetic valve endocarditis (inflammation and infection involving the heart valves and lining of the heart chambers) remains associated with a high one-year mortality rate and early valve replacement does not appear to be associated with lower mortality compared with medical therapy according to a study by Tahaniyat Lalani, M.D., M.H.S., of the Naval Medical Center, Portsmouth, Virginia, and colleagues.
PVE occurs in approximately 3 percent to 6 percent of patients within five years of valve implantation and is associated with significant morbidity and mortality, according ...
ANN ARBOR – Use of electronic health records can reduce the costs of outpatient care by roughly 3 percent, compared to relying on traditional paper records.
That's according to a new study from the University of Michigan that examined more than four years of healthcare cost data in nine communities. The "outpatient care" category in the study included the costs of doctor's visits as well as services typically ordered during those visits in laboratory, pharmacy and radiology.
The study is groundbreaking in its breadth. It compares the healthcare costs of 179,000 patients ...
Individual ethnic groups use psychiatric and mental health services in Scotland very differently, a study suggests.
Researchers have found that there is a significant difference in the rates of hospitalisations for mental health problems according to ethnic group.
The study also revealed that there are widely differing patterns of hospitalisation for mental health problems among non-White groups. It is the first study of its kind to be carried out in Scotland.
Researchers say that psychiatric and mental health services should be reviewed and monitored to ensure ...

A little bit of learned fear is a good thing, keeping us from making risky, stupid decisions or falling over and over again into the same trap. But new research from neuroscientists and molecular biologists at USC shows that a missing brain protein may be the culprit in cases of severe over-worry, where the fear perseveres even when there's nothing of which to be afraid.
In a study appearing the week of July 15 in the Proceedings of the National Academy of Sciences, the researchers examined mice without the enzymes monoamine oxidase A and B (MAO A/B), which sit next to ...
WASHINGTON, D.C., July 15, 2013 -- In a study released last week, education researchers found that personifying energy allowed students to grapple with difficult ideas about how energy works. Contrasted with more traditional lectures and graphs, this innovative instructional technique may be useful for teaching about other ideas in physical science, which commonly deals with things that change form over time.
Energy is a very important concept across many fields of science, and is a key focus of the new national science standards. Energy is also a central player in several ...
