This systematic review examined 14 U.S. studies published since 2000 reporting prevalence estimates for intellectual disability (ID) or developmental disability (DD). Prevalence rates for children were between 11.0 and 13.4 per 1,000 for ID and between 45.8 and 69.9 per 1,000 for DD using data from 2010 or later. A 2015 Ohio study of adults yielded a prevalence estimate of 41.0 per 1,000 for DD. The only study of ID in adults and the only study incorporating DD Act definitions used the 1994/1995 NHIS-D yielding prevalence estimates for ID and/or DD of 38.2 per 1,000 for children birth to 5 years, 31.7 for children 6 to 18 years, and 7.9 per 1,000 for adults. Notable differences in prevalence estimates by age and operational definition have important implications for public policy and research. Serious surveillance gaps limit our understanding of service utilization rates, unmet needs, and health and other outcomes for adults with ID or DD.

Self-directed home and community based services (HCBS) waiver services and supports for people with intellectual and developmental disabilities (IDD) have become a viable and widely used method of service provision in the United States. Grounded in theories of self-determination, previous literature on self-direction has suggested high satisfaction and positive outcomes for people who use self-directed programs as well as cost savings for state IDD service systems. This study explored the ways in which state IDD service administrators think about how self-direction may be used as a method of achieving cost savings while providing opportunities for people with IDD and their families to exercise choice and control. Informed by 54 high-level IDD service administrators in 34 states, and guided by a thematic analysis approach to data interpretation, the study found evidence that administrators typically see strong potential for self-direction to have cost-savings benefits, while also fostering choice. In the current political climate, the need for cautious fiscal stewardship may become a stronger driving force behind self-direction for people with IDD in the United States.

The Nanotechnology Characterization Laboratory's (NCL) unique set-up has allowed our lab to handle and test a variety of nanoparticle platforms intended for the delivery of cancer therapeutics and/or imaging contrast agents. Over the last six years, the NCL has characterized more than 250 different nanomaterials from more than 75 different investigators. These submitted nanomaterials stem from a range of backgrounds and experiences, including government, academia and industry. This has given the NCL a unique and valuable opportunity to observe trends in nanoparticle safety and biocompatibility, as well as note some of the common mistakes and oversights of nanoformulation. While not exhaustive, this article aims to share some of the most common pitfalls observed by the NCL as they relate to nanoparticle synthesis, purification, characterization and analysis.

Esophageal duplication cysts are uncommon embryologic entities that are often discovered incidentally. When identified, complete excision is the recommended treatment regardless of symptoms. We report the case of a 2-year-old boy with a distal esophageal duplication cyst discovered incidentally during laparoscopy for fundoplication. The esophageal duplication cyst was completely resected and a 360-degree fundoplication was then constructed, incorporating the cyst resection site. This is only the second report describing complete laparoscopic excision of an incidentally discovered esophageal duplication cyst in a child. This method is a safe and effective way of managing these lesions.
