The proposed changes may affect the proportion of individuals who qualify for a diagnosis of autism spectrum disorder, according to a study by Yale Child Study Center researchers published in the April issue of the Journal of the American Academy of Child & Adolescent Psychiatry.
The proposed changes to the diagnostic definition will be published in the fifth edition of the American Psychiatric Association's (APA) "Diagnostic and Statistical Manual of Mental Disorders (DSM-5)."
"Given the potential implications of these findings for service eligibility, our findings offer important information for consideration by the task force finalizing DSM-5 diagnostic criteria," said Yale Child Study Center director Fred Volkmar, M.D., who conducted the study with colleagues Brian Reichow and James McPartland.
Volkmar and his team performed an analysis of symptoms observed in 933 individuals evaluated for autism in the field trial for DSM-4. They found that about 25 percent of those diagnosed with classic autism and 75 percent of those with Asperger's Syndrome or pervasive developmental disorder, not otherwise specified, would not meet the new criteria for autism. The study also suggests that higher-functioning individuals may be less likely to meet the new criteria than individuals with intellectual disabilities.
Volkmar cautioned that these findings reflect analyses of a single data set and that more information will be provided by upcoming field trials overseen by the APA. He stressed that it is critical to examine the impact of proposed criteria in both clinical and research settings.
"Use of such labels, particularly in the United States, can have important implications for service," he said. "Major changes in diagnosis also pose issues for comparing results across research studies."

Among the general public, solar thermal energy is currently associated with dark blue, rectangular collectors on building roofs. Technologies are needed for aesthetically high quality architecture which offer the architect more room for manoeuvre when it comes to low- and plus-energy buildings. With the “ArKol” project, researchers at Fraunhofer ISE together with partners are currently developing two façade collectors for solar thermal energy generation, which permit a high degree of design flexibility: a strip collector for opaque façade sections and a solar thermal blind for transparent sections. The current state of the two developments will be presented at the BAU 2017 trade fair.
As part of the “ArKol – development of architecturally highly integrated façade collectors with heat pipes” project, Fraunhofer ISE together with its partners...
At TU Wien, an alternative for resource intensive formwork for the construction of concrete domes was developed. It is now used in a test dome for the Austrian Federal Railways Infrastructure (ÖBB Infrastruktur).
Concrete shells are efficient structures, but not very resource efficient. The formwork for the construction of concrete domes alone requires a high amount of...
Many pathogens use certain sugar compounds from their host to help conceal themselves against the immune system. Scientists at the University of Bonn have now, in cooperation with researchers at the University of York in the United Kingdom, analyzed the dynamics of a bacterial molecule that is involved in this process. They demonstrate that the protein grabs onto the sugar molecule with a Pac Man-like chewing motion and holds it until it can be used. Their results could help design therapeutics that could make the protein poorer at grabbing and holding and hence compromise the pathogen in the host. The study has now been published in “Biophysical Journal”.
The cells of the mouth, nose and intestinal mucosa produce large quantities of a chemical called sialic acid. Many bacteria possess a special transport system...

Fiber-reinforced plastics (FRP) are frequently used in the aeronautic and automobile industry. However, the repair of workpieces made of these composite materials is often less profitable than exchanging the part. In order to increase the lifetime of FRP parts and to make them more eco-efficient, the Laser Zentrum Hannover e.V. (LZH) and the Apodius GmbH want to combine a new measuring device for fiber layer orientation with an innovative laser-based repair process.
Defects in FRP pieces may be production or operation-related. Whether or not repair is cost-effective depends on the geometry of the defective area, the tools...
