Information Avoidance and Information Seeking Among Parents of Children With ASD.

We estimated the effects of information avoidance and information seeking among parents of children diagnosed with autism spectrum disorder (ASD) on age of diagnosis. An online survey was completed by 1,815 parents of children with ASD. Children of parents who self-reported that they had preferred "not to know," reported diagnoses around 3 months later than other children.

Clinical signs associated with earlier diagnosis of children with autism Spectrum disorder.

Background: The objective of this study is to gain new insights into the relationship between clinical signs and age at diagnosis.

Method: We utilize a new, large, online survey of 1743 parents of children diagnosed with ASD, and use multiple statistical approaches. These include regression analysis, factor analysis, and machine learning (regression tree).

Grandma knows best: Family structure and age of diagnosis of autism spectrum disorder.

This pilot study estimates the effects of family structure on age of diagnosis, with the goal of identifying factors that may accelerate or delay diagnosis. We conducted an online survey with 477 parents of children with autism. In addition, we carried out novel, follow-up surveys of 196 "friends and family," who were referred by parents.

The cost-effectiveness of low-dose CT screening for lung cancer: preliminary results of baseline screening.

Background: Low-dose CT scan screening greatly improves the likelihood of detecting small nodules and, thus, of detecting lung cancer at a potentially more curable stage.

Methods: To evaluate the cost-effectiveness of a single baseline low-dose CT scan for lung cancer screening in high-risk individuals, data from the Early Lung Cancer Action Project (ELCAP) was incorporated into a decision analysis model comparing low-dose CT scan screening of high-risk individuals (ie, those > or = 60 years with at least 10 pack-years of cigarette smoking and no other malignancies) to observation without screening. Cost-effectiveness was expressed as the incremental cost per year of life saved.
