Some great inventions were on view this week at the second annual Boston Children’s Hospital Innovators Showcase. Hosted by the hospital’s Innovation Acceleration Program and Technology & Innovation Development Office, the event featured everything from virtual reality goggles with gesture control to biomedical technologies. Below are a few new projects that caught Vector’s eye (expect to hear more about them in the coming months), a kid-friendly interview about the SimLab and list of inventions kids themselves would like to see.

David Hunter, MD, PhD, chief of Ophthalmology at Boston Children’s Hospital, gets a lot of questions from parents, but the number one question is: “What can my baby see?”
That depends. How old is the baby?
Five days after birth, she might see something like the image at left; at 3 months, the image at right:
At 6 months and 9 months, there’s increasing color and resolution:
Sung-Yun Pai, MD, a pediatric hematologist/oncologist at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, was lead author on two recent articles on severe combined immune deficiency (SCID) in The New England Journal of Medicine. The first reviewed outcomes after bone marrow transplantation; the second reported the first results of a new international gene therapy trial for X-linked SCID. Here, she discusses what’s known to date about these therapies.
Q: What is SCID?
A: SCID is a group of disorders that compromise the blood’s T cells, a key component of the immune system that helps the body fight common viral infections, other opportunistic infections and fungal infections. T-cells are also important for the development of antibody responses to bacteria and other microorganisms. A baby born with SCID appears healthy at birth, but once the maternal antibodies that the baby is born with start to wane, the infant is at risk for life-threatening infections. Unless diagnosed and treated—with a stem cell transplant from a healthy donor or a more experimental therapy like gene therapy—babies with SCID typically die before their first birthday.
It’s long been known that a master clock in the hypothalamus, deep in the center of our brain, governs our bodily functions on a 24-hour cycle. It keeps time through the oscillatory activity of timekeeper molecules, much of which is controlled by a gene fittingly named Clock.
It’s also been known that the timekeeper molecules and their regulators live outside this master clock, but what exactly they do there remains mysterious. A new study reveals one surprising function: they appear to regulate the timing of brain plasticity—the ability of the brain to learn from and change in response to experiences.
“We found that a cell-intrinsic Clock may control the normal trajectory of brain development,” says Takao Hensch, PhD, a professor in the Departments of Molecular and Cellular Biology and Neurology at Harvard University and a member of the F.M. Kirby Neurobiology Center at Boston Children’s Hospital.
Exome sequencing comes to the clinic (JAMA)
An approachable and thorough summary of the growing trend, describing the ways in which sequencing can help provide a diagnosis, the diagnostic yield (as high as 40 percent or more, depending on the population), how often the results have changed treatment decisions and the question of who pays.
Who Owns CRISPR? (The Scientist)
Excellent coverage of the escalating patent scramble for genome editing.
Doctors Make House Calls On Tablets Carried By Houston Firefighters (NPR)
Interesting use of telemedicine in Houston, where many people call 911 in non-emergency situations. EMTs carry tablets, and can have callers chat with a physician on a video app, avoiding the need to take them to the ED.

Next week—on April 15—Boston-area visitors can sample inventions and technologies from around Boston Children’s Hospital, some in development and some already in use. More than 20 medical innovations will be on display in an interactive “science fair” format. We’ll be demonstrating a variety of medical devices, mobile applications, software IT innovations, wearables and bioengineering innovations. It’s free and open to the public.
Can sequencing of newborns’ genomes provide useful medical information beyond what current newborn screening already provides? What results are appropriate to report back to parents? What are the potential risks and harms? How should DNA sequencing information be integrated into patient care?
Four teams from across the country will converge this week (April 8–10) in Kansas City, Mo., to address these questions and share learnings from NIH-funded pilot projects. The four teams, comprising the NIH’s Newborn Sequencing In Genomic medicine and public HealTh (NSIGHT) project, will give updates on their work at the 6th Annual Pediatric Genomics Conference, hosted by Children’s Mercy Kansas City.
Bubble wrap used for cheap blood and bacteria tests (New Scientist)
Snap, crackle, pop are the familiar sounds of bubble wrap. According to George Whitesides at the Wyss Institute for Biologically Inspired Engineering at Harvard University, the cheap packing material may be popping up in the near future as a diagnostic tool, replacing costlier 96-well plates.
Nearly half of all pre-schoolers with ADHD are on medication (Washington Post)
The American Academy of Pediatrics calls for children under 6 with ADHD to engage in behavioral therapy before taking medication. Yet according to a national survey published in the Journal of Pediatrics, nearly half of preschool-aged children are on medication for the condition, and more than a fifth were receiving neither of the recommended therapies.
Device developers tend to focus on the FDA approval process—PMAs and 510(k) clearances—while overlooking another major challenge: getting insurers to cover the device. Before approaching investors, and certainly before doing any studies, keep payers in mind, advises Maren Anderson, president of MDA Consulting, Inc., which specializes in reimbursement planning.
In the old days, doctors prescribed, and insurers paid. Under health care reform, that’s changed, says Anderson.
Rett syndrome, a neurodevelopmental disorder affecting mostly girls, takes away the ability to speak, and this makes the condition hard to reliably measure and assess. But children with Rett syndrome also display distinctive hand movements or stereotypies, including hand wringing, clasping and other repetitive hand movements, visible in many of these videos. With help from a grant from Boston Children’s Hospital’s Innovation Acceleration Program, researchers are transforming these hand movements into an assessment tool.
Until now, there has been no quantitative measure for monitoring Rett hand movements. Adapting commercially available wearable sensor technology, biomedical engineering researcher Heather O’Leary has created a bracelet-like device not unlike Fitbit, another wearable accelerometer used to monitor exercise activity levels.
