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.
If you’re in New York City in the next few months, pop into the Museum of Modern Art (MoMA) and stop by the “This Is For Everyone: Design For The Common Good” exhibit. There—alongside displays dedicated to the “@” symbol, the pin icon from Google Maps and bricks made from living mushroom roots—you’ll find three small silicone blocks mounted on a wall panel.
Earlier this month, MoMA announced its plans to include the chips as part of their exploration of contemporary design in the digital age. In the museum’s eyes, organs-on-chips are more than a way to model disease in a complex, living system—they’re also art.
Single-Dose Cures for Malaria, Other Diseases (MIT Technology Review)
Pills that deliver a full course of treatment in one swallow could, or “super pills,” could simplify the treatment of diseases such as malaria and potentially produce cost savings that stretch into the $100 billion a year range, according to Bob Langer, PhD, from the Massachusetts Institute of Technology.
Our daughter, Saoirse, was diagnosed with cancer when she was 11 months old. Her care, safety and comfort were our first priorities. When she had a PICC line and later a central line placed to infuse drugs and fluids, we saw a need for a better way to keep these lines safe and secure without using skin-damaging tape and irritating mesh netting. Saoirse was tugging at her lines and trying to pull off the tape, so I handmade a fabric sleeve for her PICC line and a chest wrap for her central line, and she went back to playing and being a kid.
Vaccines to protect against infectious disease are the single most effective medical product, but developing new ones is a challenging and lengthy process, limiting their use in developing countries where they are most needed. Once a new vaccine is developed, it undergoes animal testing, which is time-consuming and does not necessarily reflect human immunity.
“It can take decades from the start of vaccine development to FDA approval at huge cost,” says Ofer Levy, MD, PhD, a physician and researcher in the Division of Infectious Diseases at Boston Children’s Hospital. “We are working on making the process faster and more affordable.”
A variety of new strategies are emerging to facilitate vaccine development and delivery:
1. Modular approaches to vaccine production
The Multiple Antigen Presenting System (MAPS) is one innovative modular method to more efficiently produce vaccines that provide robust immunity.
Last week was a good week for neuroscience. Boston Children’s Hospital received nearly $2.2 million from the Massachusetts Life Sciences Center (MLSC) to create a Human Neuron Core. The facility will allow researchers at Boston Children’s and beyond to study neurodevelopmental, psychiatric and neurological disorders directly in living, functioning neurons made from patients with these disorders.
Patient-derived neurons are ideal for modeling disease and for preclinical screening of potential drug candidates, including existing, FDA-approved drugs. Created from induced pluripotent stem cells (iPSCs) made from a small skin sample, the lab-created human neurons capture disease physiology at the cellular level in a way that neurons from rats or mice cannot.
Tools like CRISPR could give us the power to alter humanity’s genetic future. A group of senior American scientists and ethicists have called for a moratorium any attempts to create genetically engineered children using these technologies until there can be a robust debate.
While studying quality of care in the 1990s, Mark Schuster, MD, PhD found that few studies on pediatric quality had been conducted. The typical explanation that he was given was that the federal government wasn’t funding research into quality measures because children on Medicaid don’t drive federal health-care costs nearly as much as adults on Medicaid and Medicare do.
But Schuster, chief of General Pediatrics at Boston Children’s Hospital and William Berenberg Professor of Pediatrics at Harvard Medical School, believes there have been other challenges in measuring care quality in children. In an acceptance speech upon receiving the 2014 Douglas K. Richardson Award for Perinatal and Pediatric Healthcare Research, published today in the journal Pediatrics (PDF), Schuster points to factors including the relative rarity of many pediatric conditions and that many of the benefits of excellent pediatric care are not observed until adulthood.

It is said that necessity is the mother of invention, so when David Casavant, MD, observed his teenagers routinely using FaceTime and Skype to connect with friends, he had a lightbulb moment. Could videoconferencing help him support his patients—children and young adults who require mechanical ventilation in their homes?
“It just seemed obvious,” says Casavant, a physician in the Boston Children’s Hospital’s CAPE (Critical Care, Anesthesia and Perioperative Extension & Home Ventilation) program, part of the Division of Critical Care Medicine. “In my work we are always weighing the risk versus the benefit to the patient. It’s easy for ambulatory patients to swing by their primary care office, get a prescription or go for an x-ray, but that’s not the case for patients who have to have their oxygen, their suction or their ventilator. If you don’t have to put them on the road you are better off not to.”
Back in the day, the 1980s to be specific, there was a brief fad around amber-on-black computer screens (as opposed to green-on-black or white-on-black) for supposed ergonomic reasons. My computer had one, along with its 5 ¼” floppy drives (remember those?).
More recently, with kids texting at night and people logging late hours on computers and devices, there’s been a recognition that artificial light at night is bad for sleep and disruptive to physiology overall, with blue light increasingly recognized as the culprit.
That’s given birth to some new fads. You can now download programs to eliminate blue light from your computer screen at night or buy amber-tinted glasses for computing and gaming to “filter the harsh spectra” of light. Airlines are using “mood” lighting to mimic sunrises and sunsets, which supposedly reduces jetlag.
In a paper in Neuron last week, Alan Emanuel and Michael Do, PhD, of the F.M. Kirby Neurobiology Center at Boston Children’s Hospital and Harvard Medical School provide some science to support and inform these fads, as well as the use of light therapy for conditions like seasonal affective disorder.
