Sadie McCallum’s own life led her to become an inventor. She’s 9, has cerebral palsy, for which she’s seen at Boston Children’s Hospital, and relies on a walker to get around. “It would be SO much easier if my walker was more like an all-terrain vehicle and could go over curbs or stairs,” she says.
This year, in third grade, Sadie took part in her school’s annual Invention Convention and designed and built the Amazing Curb Climber. She sketched the design, and her family helped her with the planning, drilling, sawing and assembly. The end product combined two of Sadie’s old walkers and six lawn mower wheels (three on either side) to create an all-terrain design, plus two smaller wheels in back. Her dad helped build a portable curb for testing and demo purposes.
The invention won first place for Best Use of a Wheel and second place for Kids’ Choice. Sadie went on to the regional Invention Convention, where she took the first place for the Special Needs Award as well as the Microsoft Technology Award.
New smartphone-based diagnostic tools are enabling consumers to take their temperatures, diagnose simple skin conditions and much more. As advanced smartphone imaging puts more and more capabilities in patients’ hands, it’s no surprise that clinicians and numerous digital health startups are leveraging them.
Pediatric medicine just took a step for the better in Boston’s Longwood Medical Area with a new, expanded pediatric Simulation (SIM) Center — a dedicated space where doctors, nurses and other staff can rehearse tough medical situations or practice tricky or rare procedures in a clinical setting that looks and feels real.
But clinicians aren’t the only ones who will be using the new 4,000-square-foot facility, which incorporates real medical equipment, set design and special effects.
Families can get hands-on practice with medical equipment they’ll be using at home. Inventors and “hackers” can develop and test new devices or software platforms and see how they perform in a life-like clinical environment. Planned hacks, for example, will explore different medical and surgical applications for voice-activated and gesture-controlled devices. …
Through smart home hubs and the growing Internet of Things, people can now control lights, thermostats and other appliances and get information and entertainment with their always-connected digital devices. Consumers have widely adopted home automation products like Nest from Google and ecosystems like Apple’s HomeKit and Amazon’s Alexa.
But home hubs also have the potential to achieve the promise of connected health — access to health care services anywhere and anytime.
Home hubs can deliver enormous value as a means of health care delivery — not just helping casual consumers become familiar with their health and take preventive measures, but also helping manage complex care for patients with chronic illness and supporting timely decision making by clinical teams. Everybody involved with a person’s care can be plugged in, enabling coordination across providers and caregivers in a way that’s increasingly intuitive and meaningful. …
When Sarah and Jon Morris’ twins were born nine weeks early, they embarked on a journey largely dictated by their children’s medical needs. While son Drew was thriving, daughter Emma was severely compromised and was transferred to Boston Children’s Hospital’s Neonatal Intensive Care Unit (NICU). “We felt powerless,” remembers Jon. “Every time we thought we had made progress, we had a setback. It’s always two steps forward, one step back in the NICU. That backwards step always hit the hardest.”
After 296 days at Boston Children’s, Emma went home tethered to breathing and feeding tubes. The Morrises had a pulse oximeter at home to regularly test Emma’s blood oxygen level.
There were frustrating limitations to Emma’s oximeter: …

Zika’s surface in stunning detail; mosquito tactics
We haven’t curbed the Zika epidemic yet. But cryo-electron microscopy — a newer, faster alternative to X-ray crystallography — at least reveals the structure of the virus, which has been linked to microcephaly (though not yet definitively). The anatomy of the virus’s projections gives clues to how the virus is able to attach to and infect cells, and could provide toeholds for developing antiviral treatments and vaccines. Read coverage in the Washington Post and see the full paper in Science.
Meanwhile, as The New York Times reports, scientists are coming together in an effort to control Zika by genetically manipulating the mosquito that spreads it, Aedes aegypti. …
An anterior cruciate ligament (ACL) tear can be a devastating sports injury. Every year, 400,000 people, many of them teen and young adult athletes, sustain ACL injuries or tears. Martha Murray, MD, an orthopedic surgeon at Boston Children’s Hospital, worked with a team of colleagues to create a new procedure known as bridge-enhanced ACL repair (BEAR) that encourages natural healing. Watch this animation to see how it works:
Why do surgeons need a better way to repair ACL injuries?
The current standard of care, surgical ACL reconstruction, is a good solution. But it is linked with a 20 percent risk of re-tearing the ACL, and many young patients face an increased risk of arthritis. Instead of removing the torn ACL and replacing it with a tendon graft, the BEAR technique uses a special protein-enriched sponge to encourage the torn ends to reconnect and heal. The researchers have completed a 20-patient safety trial and are enrolling additional patients in a 200-patient clinical study.

Blood-brain barrier on chip
The blood-brain barrier protects the brain against potentially damaging molecules, but its gate-keeping can also prevent helpful drugs from getting into the central nervous system. Reporting in PLoS One, a team at the Wyss Institute for Biologically Inspired Engineering describes a 3-D blood-brain barrier on a chip — a hollow blood vessel lined with living human endothelial cells and surrounded by a collagen matrix bearing human pericytes and astrocytes. …
What if I told you that there was a new technology that improved outcomes for patients of all ages, reduced pain and suffering, reduced time in the operating room, reduced anesthetic times and, the more you did it, the better it benefited patients. And here’s the kicker — it has no side effects. And it’s available everywhere care is delivered.”
Judges include representatives from the four founding hospitals — Boston Children’s Hospital, Cincinnati Children’s Hospital, Texas Children’s Hospital and Children’s Hospital of Philadelphia — and from Sesame Workshop, whose recently announced Sesame Ventures plans to support companies that “help kids grow smarter, stronger and kinder.”
John Brownstein, PhD, chief innovation officer at Boston Children’s and one of the judges on the panel, agrees with that mission. “When it comes to innovation, pediatrics is often a second thought or gets left out altogether,” he says. “I’m extremely impressed with the landscape this year and the breadth of startup ideas.” …
