Hematopoietic hierarchy aging blood cell hematopoietic stem cell blood disorder Derrick Rossi

Blood-forming hematopoietic stem cells (top) give rise to all blood and immune cell types. In children with SCID, the steps leading to immune cells are broken.

In the world of fatal congenital immunodeficiency diseases, good news is always welcome, because most patients die before their first birthday if not treated. Babies with severe combined immunodeficiency disease, aka SCID or the “bubble boy disease,” now have more hope for survival thanks to two pieces of good news.

Transplants are looking up

First came a July paper in the New England Journal of Medicine (NEJM) by the Primary Immune Deficiency Treatment Consortium. This North American collaborative analyzed a decade’s worth of outcomes of hematopoietic stem cell transplant (HSCT), currently the only standard treatment option for SCID that has a chance of providing a permanent cure.

magnetic suturing needle

A magnetic needle and thread lets surgeons maneuver in tight spots.

The current method of suturing used in surgery—stitching with a needle and thread—has been around for thousands of years. Kaifeng Liu, MD, a research fellow at Boston Children’s Hospital, hopes to reimagine this fundamental operating room practice. His workbench is filled with various prototypes of a magnetic needle, a device he hopes will make suturing simpler, faster and more efficient for researchers and clinicians alike.

“Sometimes it is the simplest things in medicine that stay the same over time,” says Liu, whose invention will be featured later this week at Boston Children’s Hospital’s Global Pediatric Innovation Summit + Awards 2014 (October 30-31). Full story »

Delivering a baby MEG

by Kipaya Kapiga on October 24, 2014

This array of sensors surrounding a baby's head will give researchers and eventually clinicians an clear and sharp image of neural activity.

This array of sensors surrounding a baby's head will give researchers and eventually clinicians a high-resolution image of neural activity.

Imagine you’re a clinician or researcher and you want to find the source of a newborn’s seizures. Imagine being able to record, in real time, the neural activity in his brain and to overlay that information directly onto an MRI scan of his brain. When an abnormal electrical discharge triggered a seizure, you’d be able to see exactly where in the brain it originated.

For years, that kind of thinking has been the domain of dreams. Little is known about infant brains, largely because sophisticated neuroimaging technology simply hasn’t been designed with infants in mind. Boston Children’s Hospital’s Ellen Grant, MD, and Yoshio Okada, PhD, are debuting a new magnetoencephalography (MEG) system designed to turn those dreams into reality. Full story »

Dallas map Ebola electronic health records

(Google Maps)

The Ebola situation in Dallas—with one patient death, two nurse exposures, dozens under quarantine, and talk last week of declaring a state of emergency in the city—has thrown into stark relief the gaps between public health and frontline clinical care. But those gaps also present opportunities to make public health data work harder and to change how doctors approach clinical care in times when events and information are changing at Internet speed.

That’s the gist of an editorial by Boston Children’s Hospital’s Kenneth Mandl, MD, MPH, published Monday in the Journal of the American Medical Association.

It comes down to making electronic health records (EHRs) work more flexibly, in ways that help promote situational awareness among clinicians during times of crisis and flag instances when a patient’s condition may require more attention than usual. Full story »

Hacking Pediatarics brainstorming wall

(Dana Hatic for MedTech Boston)

What are the pain points in pediatrics? There are at least 37: the number of clinicians, parents and others who lined up at the podium last weekend to pitch problems they hoped to solve at the second annual Hacking Pediatrics.

The hackathon, produced by Boston Children’s Hospital in collaboration with MIT Hacking Medicine, brought out many common themes: Helping kids with chronic illnesses track their symptoms, take their meds and avoid lots of clinic visits. Helping parents coordinate their children’s care and locate resources. Helping pediatric clinicians make better decisions with the right information at the right time.

Hackathons have a simple formula: Pitch. Mix. Hack. Get Feedback. Iterate. Repeat—as many times as possible. Full story »

Global Pediatric Innovation Summit Awards big dataWhere is the next generation of therapeutic innovations going to come from? Population-level genomic studies? The fitness trackers on everyone’s wrist? Mining electronic medical records? People’s tweets, Yelps and Facebook posts?

How about all of the above?

What all of these things have in common is data. Lots of it. Some of it represents kinds of data that didn’t exist 5 or 10 years ago, but all of it is slowly beginning to fuel the pharma sector’s efforts to create the next blockbuster drug or targeted therapeutic.

At least, it should be. Full story »

Shark Tanks in health care

Health care institutions, universities and even the U.S. government are helping innovators hone their pitches and get backing.

On ABC’s reality show “Shark Tank,” a panel of veteran investors listens to business pitches for everything from new dietary supplements to a nail salon for men. After asking tough questions, each shark either backs the venture—sometimes not for the reasons you’d think—or more likely declares, “I’m out.”

It’s a great infotainment formula—even my 10-year-old daughter is a fan—but it’s also a hit beyond the living room. Health care organizations are increasingly borrowing the “Shark Tank” script to get new ideas or to bankroll their own innovations. Boston Children’s Hospital is doing so at our Global Pediatric Innovation Summit + Awards (Oct. 30-31), bringing in “Shark Tank”’s Daymond John to moderate. But we’re certainly not alone.

Tamiflu influenza neuraminidase inhibitors conflicts of interest

(stanrandom/Flickr)

This winter, if your doctor suggests that you take Tamiflu, you might want to ask for a conflict of interest statement: a new study suggests that doctors who received payments from the makers of flu-fighting neuraminidase inhibitors—drugs like Tamiflu® and Relenza®—were more likely to view the drugs’ prowess in a favorable light.

In the study, published last week in the Annals of Internal Medicine, a team led by Boston Children’s Hospital’s Florence Bourgeois, MD, MPH, tallied up the financial connections of doctors who participated in 37 reviews of neuraminidase inhibitors.

While it’s been unclear for years whether these drugs really are effective against influenza, it was crystal clear that financial relationships are associated with positive reviews. Full story »

Breast cancer cholesterol ezetimibe Zetia angiogenesisYou are what you eat, the saying goes. For some conditions (think cardiovascular disease or type 2 diabetes), there are clear connections between diet, health and illness.

For breast cancer, the picture is less clear. Many epidemiologic and laboratory studies have examined the Western diet (in particular, cholesterol) and its relation to breast cancer, with conflicting results.

“There’s been a raging debate in the field,” says Christine Coticchia, PhD, who works in the laboratory of Boston Children’s Hospital’s Vascular Biology Program director, Marsha Moses, PhD. “The biology of cancer and of cholesterol are so complex, and there are many subsets of breast cancer. In order to find any connections, you have to ask very specific questions.”

Banding together with Keith Solomon, PhD, in Boston Children’s Urology Department,  Coticchia and Moses asked whether dietary cholesterol might encourage progression of the most aggressive, so-called “triple-negative” breast tumors. As they report in the American Journal of Pathology, they found a big impact, at least in mice. But it’s too early to say just yet that cutting back on cholesterol will help women avoid breast cancer. Full story »
