(Press-News.org) The incidence of a potentially life-threatening complication of diabetes, diabetic ketoacidosis, in youth in Colorado at the time of diagnosis of type 1 diabetes increased by 55 percent between 1998 and 2012, suggesting a growing number of youth may experience delays in diagnosis and treatment, according to a study in the April 21 issue of JAMA, a theme issue on child health.
Diabetic ketoacidosis (DKA) at the time of type 1 diabetes (T1D) diagnosis has detrimental long-term effects and is characterized by dangerously high blood sugar and the presence of substances in the blood known as ketones. It may reflect delayed access to health care, lower quality of care, or income inequality. Little is known about long-term trends of DKA in the United States, according to background information in the article.
Arleta Rewers, M.D., Ph.D., of the University of Colorado School of Medicine, Aurora, and colleagues examined trends in DKA at T1D diagnosis between 1998 and 2012 in Colorado and factors associated with DKA. Between this time period, youth diagnosed with T1D before age 18 years at any medical facility were included in the study if a Colorado resident and followed up at the Barbara Davis Center for Diabetes in Denver, which serves more than 80 percent of youth with diabetes in Colorado. Standard criteria were used to define DKA. Data were extracted from medical records.
Diabetic ketoacidosis was present in 1,339 of 3,439 youth (39 percent) at T1D diagnosis. Youth with DKA had a median age of 9.4 years, 54 percent were male, and 76 percent were white. The proportions with DKA increased significantly, especially after 2007 (30 percent in 1998; 35 percent in 2007; 46 percent in 2012). The only characteristic that changed over time was insurance, with those covered by public insurance increasing from 17.1 percent in 2007 to 37.5 percent in 2012. Younger age and African American race were associated with higher risk, whereas private insurance and history of T1D in a first-degree relative were associated with lower risk.
The authors note that the incidence of DKA found in this study is consistent with incidences in countries with poor access to health care and low community and physician awareness of diabetes, and is much higher than incidences reported in Canada or the United Kingdom.
"Some of the factors associated with DKA at diagnosis are potentially modifiable. For example, the association with family history suggests the importance of awareness of diabetic symptoms. However, economic factors are more difficult to modify. Increasing incidence of DKA correlated temporally with an increase in Colorado child poverty prevalence from 10 percent in 2000 to 18 percent in 2012. The recent increase of DKA incidence among youth with private insurance may be related to proliferation of high-deductible health plans."
"To our knowledge, this is the only report of increasing incidence of DKA in the developed world. Further research on the reasons for the increase and interventions to decrease the incidence are warranted."

A multi-site study sponsored by the National Institute of Mental Health (NIMH) finds young children with autism spectrum disorder and serious behavioral problems respond positively to a 24-week structured parent training. The benefits of parent training endured for up to six months post intervention.
Published in the April 21 issue of the Journal of the American Medical Association the study found parent training was more effective in reducing disruptive and aggressive behavior than 24 weeks of parent education. Parent training provided parents with specific strategies ...
Researchers from the University of Tokyo have revamped an old e-paper concept to make an inexpensive handwriting-enabled e-paper well suited to large displays like whiteboards. They describe the e-paper in the Journal of Applied Physics, from AIP Publishing.
Traditional ink and paper is convenient for both reading and writing. In e-paper development the writing feature has generally lagged behind. Handwriting-enabled displays mainly show up in the inexpensive, but feature-limited realm of children's toys, and in the high-end realm of touch-screen e-readers and smart ...
French teams from CIC Biothérapie (AP-HP/Inserm), from pediatric hematology department of Necker Hospital for Children (AP-HP), led by Marina Cavazzana, Salima Hacein Bey Albina and Alain Fischer and from Genethon led by Anne Galy (Genethon/Inserm UMR-S951), and English teams from UCL Institute of Child Health and Great Ormond Street Hospital in London led by Adrian Thrasher and Bobby Gaspar demonstrated the efficacy of gene therapy treatment for Wiskott-Aldrich Syndrome (WAS). Six children that were treated and followed for at least 9 months had their immune system ...

Scientists from the DFG Center for Regenerative Therapies Dresden, TU Dresden and the Institut für Diabetesforschung, Helmholtz Zentrum München, together with researchers from Vienna, Bristol and Denver (USA) have successfully completed the first step in development of an insulin vaccine to prevent type 1 diabetes.
As reported by these diabetes researchers in the current edition of the renowned scientific journal JAMA, evaluations of the international Pre-POINT study point to a positive immune response in persons at risk for the disease who were given oral doses ...
AURORA, Colo. (April 21, 2015) - The incidence of a potentially life-threatening complication of diabetes, called diabetic ketoacidosis, increased by 55 percent between 1998 and 2012 in youth in Colorado, according to a study by researchers from the Barbara Davis Center for Childhood Diabetes and the University of Colorado School of Medicine on the Anschutz Medical Campus.

AURORA, Colo. (April 21, 2015) - Children at risk for type 1 diabetes, who were given daily doses of oral insulin, developed a protective immune response to the disease that researchers with the Barbara Davis Center for Childhood Diabetes at the University of Colorado Anschutz Medical Campus say could possibly lay the groundwork for a vaccine against the chronic illness.
The pilot study, published Tuesday, April 21, in the Journal of the American Medical Association (JAMA), was carried out in the U.S., Germany, Austria and the United Kingdom.

Sweet potatoes from all over the world naturally contain genes from the bacterium Agrobacterium. Researchers from UGent and the International Potato Institute publish this discovery in PNAS. Sweet potato is one of the most important food crops for human consumption in the world. Because of the presence of this 'foreign' DNA, sweet potato can be seen as a 'natural GMO.'
The researchers discovered the foreign DNA sequences of Agrobacterium while searching the genome - this is the entire DNA-code - of sweet potato for viral diseases. Instead of contributing this peculiar ...
Female liver cells, and in particular those in menopaused women, are more susceptible to adverse effects of drugs than their male counterparts, according to new research carried out by the JRC. It is well known that women are more vulnerable when it comes to drug-induced liver effects, but it's the first time it has been shown that there are differences at cellular level. The findings are striking and clinically relevant, and emphasise the importance of considering sex-based differences in human health risk assessment.
In this study, five prevalently used drugs (diclofenac, ...
WORCESTER, MA -- In a promising breakthrough for smokers who are trying to quit, neuroscientists at the University of Massachusetts Medical School and The Scripps Research Institute have identified circuitry in the brain responsible for the increased anxiety commonly experienced during withdrawal from nicotine addiction.
"We identified a novel circuit in the brain that becomes active during nicotine withdrawal, specifically increasing anxiety," said principal investigator Andrew Tapper, PhD , associate professor of psychiatry. "Increased anxiety is a prominent nicotine ...
