(Press-News.org) A study based on a nationally representative sample of adults in China in 2010 indicates that nearly 12 percent of Chinese adults had diabetes and the prevalence of prediabetes was about 50 percent, according to a study in the September 4 issue of JAMA.
"Noncommunicable chronic diseases have become the leading causes of mortality and disease burden worldwide. It was estimated that 34.5 million deaths globally were due to noncommunicable diseases in 2010, which reflected a significant increase from 1990. Mortality from diabetes doubled during this period and increased to 1.3 million deaths worldwide in 2010. In addition, diabetes is a major risk factor for ischemic heart disease and stroke, which collectively killed an estimated 12.9 million people globally in 2010," according to background information in the article.
"The prevalence of diabetes has increased significantly in recent decades and is now reaching epidemic proportions in China. The prevalence of diabetes was less than 1 percent in the Chinese population in 1980. In subsequent national surveys conducted in 1994 and 2000-2001, the prevalence of diabetes was 2.5 percent and 5.5 percent, respectively. The most recent national survey in 2007 reported that the prevalence of diabetes was 9.7 percent, representing an estimated 92.4 million adults in China with diabetes."
Yu Xu, Ph.D., of the Shanghai Jiao-Tong University School of Medicine, Shanghai, China, and colleagues with the 2010 China Noncommunicable Disease Surveillance Group, conducted a study to investigate the prevalence of diabetes and glycemic control in the Chinese adult population. Using a multistage, probability sampling design, the researchers conducted a cross-sectional survey in a nationally representative sample of 98,658 Chinese adults in 2010. Plasma glucose and hemoglobin A1c levels were measured after at least a 10-hour overnight fast among all study participants, and a 2-hour oral glucose tolerance test was conducted among participants without a self-reported history of diagnosed diabetes. Diabetes and prediabetes were defined according to the 2010 American Diabetes Association criteria; whereas, a hemoglobin A1c level of END

Comparison of antibody levels for 4 different immunization schedules for PCVs
2013-09-04
The use of 4 different 13-valent pneumococcal conjugate vaccine immunization schedules in healthy term infants resulted in no statistically significant differences in antibody levels between the infants after the booster dose at 12 months of age for almost all serotypes, according to a study in the September 4 issue of JAMA.
"The World Health Organization (WHO) estimated that more than 800,000 children younger than 5 years died from pneumococcal disease in 2000, making it the leading vaccine-preventable cause of death. Since the licensure in 2000 of the first 7-valent ...
Effect of iron supplementation among children living in malaria-endemic area on incidence of malaria
2013-09-04
Children in a malaria-endemic community in Ghana who received a micronutrient powder with iron did not have an increased incidence of malaria, according to a study in the September 4 issue of JAMA. Previous research has suggested that iron supplementation for children with iron deficiency in malaria-endemic areas may increase the risk of malaria.
"In sub-Saharan Africa, malaria is a leading cause of childhood morbidity and mortality, and iron deficiency is among the most prevalent preventable nutritional deficiencies. The provision of iron to children with iron deficiency ...
Hepatitis B immunization program in Taiwan associated with reduction in chronic liver disease deaths
2013-09-04
"Hepatitis B virus (HBV) infection causes infant fulminant hepatitis (IFH), and chronic HBV infection may progress to chronic liver disease (CLD) and hepatocellular carcinoma (HCC). Taiwan launched a nationwide HBV immunization program for newborns in July 1984, which has successfully lowered the prevalence of chronic HBV carriers, incidence of HCC, and mortality of IFH in vaccinated birth cohorts. The mortality of CLD before and after HBV immunization has never been examined," write Chun-Ju Chiang, Ph.D., of National Taiwan University, Taipei, and colleagues.

Sleep boosts production of brain support cells
2013-09-04
Washington, DC — Sleep increases the reproduction of the cells that go on to form the insulating material on nerve cell projections in the brain and spinal cord known as myelin, according to an animal study published in the September 4 issue of The Journal of Neuroscience. The findings could one day lead scientists to new insights about sleep's role in brain repair and growth.
Scientists have known for years that many genes are turned on during sleep and off during periods of wakefulness. However, it was unclear how sleep affects specific cells types, such as oligodendrocytes, ...
Whole genome sequencing provides researchers with a better understanding of bovine TB outbreaks
2013-09-04
The use of whole bacterial genome sequencing will allow scientists to inexpensively track how bovine tuberculosis (TB) is transmitted from farm to farm, according to research presented this week at the Society of General Microbiology Autumn Conference.
Bovine TB is primarily a disease of cattle, caused by the bacterium Mycobacterium bovis. The disease is hugely expensive, costing the Government over £91 million in England in 2010/11.
Researchers from the University of Glasgow, working in collaboration with the Agri-Food and Biosciences Institute and the Department ...
Multi-drug pills help people stick to heart disease prevention regimens
2013-09-04
People are much more likely to take preventive medicines if they're combined in one pill, an international study has found. The findings are published today in the Journal of the American Medical Association.
Taking aspirin, cholesterol-lowering and blood pressure-lowering drugs long-term more than halves heart attack and stroke recurrence. However, only about 50 per cent of people with cardiovascular disease in high-income countries take all recommended preventive medications. In low- and middle-income countries, only five to 20 per cent do. This leaves tens of millions ...
Stressful life events significantly raise the risk of falls in older men
2013-09-04
A study of around 5,000 older men has shown that stressful life events such as death of a loved one, or serious financial problems, significantly raised the risk of falls in the year following the incident. The research is published online today in the journal Age and Ageing.
Dr Howard A. Fink of the VA Medical Center in Minneapolis and colleagues conducted a study of 5,994 community-dwelling men over the age of 65 who were enrolled in the Osteoporotic Fractures in Men (MrOS) study in six locations across the United States. 5,125 participated in a second study visit ...
Brain wiring quiets the voice inside your head
2013-09-04
DURHAM, N.C. -- During a normal conversation, your brain is constantly adjusting the volume to soften the sound of your own voice and boost the voices of others in the room.
This ability to distinguish between the sounds generated from your own movements and those coming from the outside world is important not only for catching up on water cooler gossip, but also for learning how to speak or play a musical instrument.
Now, researchers have developed the first diagram of the brain circuitry that enables this complex interplay between the motor system and the auditory ...
Promiscuity and sperm selection improves genetic quality in birds
2013-09-04
New research from the University of East Anglia has shown that females can maximise the genetic quality of their offspring by being promiscuous.
Researchers studied red junglefowl (the wild ancestor of the domestic chicken) in a collaborative project with the University of Oxford, Stockholm University and Linköping University.
Findings published today in the journal Proceedings of the Royal Society B reveal that mating with different males helps females produce offspring that are more resistant to diseases.
This is down to 'cryptic female choice' -- where an internal ...

Not a bat choice: echolocation works better than eyesight, even under adequate light
A new study in Frontiers in Physiology shows for the first time that bats catch insects by sonar as it is far more efficient than using vision, even during twilight.
Bats have eyes and may not have evolved their ultrasonic sonar from the earliest time of their existence on earth. Approximately 1000 species of bats use sonar to detect prey, despite showing considerable variation in the preferred size of their prey and their mode of hunting. But why? Many bats ...
