Mapping antibiotic resistance near you: ResistanceOpen

antibiotic resistance mapping ResistanceOpen

At the moment, it would appear the bacteria are winning. Antibiotic resistance is on the rise globally (in part because much of the public may not really understand how antibiotics work), threatening doctors’ ability to treat bacterial infections and potentially making surgery, chemotherapy and other medical procedures whose safety depends on antibiotic prophylaxis more risky.

Mapping antibiotic resistance — which bacteria are resistant to which drugs, and where — can help clinicians and public health officials decide how best to focus their control efforts. The challenge to date has been compiling resistance data in geographically useful ways.

“The data about antibiotic resistance are fragmented across laboratories and hospitals globally,” says Derek MacFadden, MD, a doctoral student at the Harvard T.H. Chan School of Public Health who is working with the HealthMap team in Boston Children’s Computational Health Informatics Program. “Most of the data that are available are very high level, so you can’t get an understanding of regional-level antibiotic resistance.”

This is where ResistanceOpen could come in handy. This new tool, launched by HealthMap team this week during the World Health Organization’s World Antibiotic Awareness Week, provides a window into regional and local antibiotic resistance patterns across the globe.

Innovation Tank: And the winner is … AIR

Innovation Tank
Kevin Cedrone presents AIR to the judges at the Innovation Tank

“These start-ups are really looking to change the world. [They won’t be] the next Uber or Facebook. [Instead] they will really affect lives in the pediatric space,” said Troy Carter, founder and CEO of the entertainment company Atom Factory and newly named guest shark on ABC’s “Shark Tank,” as he introduced the Innovation Tank at the Boston Children’s Hospital Global Pediatric Innovation Summit + Awards.

Though each of the three participating innovations promised a tremendous impact on kids, the six judges agreed on the ultimate Innovation Tank winner and awarded a $30,000 investment to the Augmented Infant Resuscitator (AIR).

Four emerging advances in childhood cancer

girl-in-jfcThe 20th century saw great strides in curing childhood cancer, thanks primarily to the discovery that broadly toxic chemotherapy agents could kill malignant cells. Once virtually incurable, pediatric cancer now has an overall long-term survival rate topping 80 percent.

In the 21st century, attention is turning to additional, less toxic developments in cancer therapy. Lisa Diller, MD, Chief Medical Officer of Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, cites four coming changes:

  • Precision medicine treatments targeting specific genetic and epigenetic pathways
  • Immunotherapy drugs gaining FDA approval
  • Innovations to reduce treatment toxicity
  • A stronger focus on improving survival of childhood cancer globally.

The MERS death rate in Saudi Arabia is double that in South Korea. Why?

The Middle East respiratory syndrome (MERS) virus outbreak in South Korea is essentially over. (Not so in Saudi Arabia, where the virus first emerged, though—authorities there have reported a major uptick in new MERS cases in recent days.) And while the country gets back on its feet, some interesting data are starting to come out, especially about the outbreak’s case fatality rate (CFR; the percent of patients infected with the virus who died from it).

John Brownstein, PhD, and Maimuna Majumder, MPH, from Boston Children’s HealthMap team just reported in the journal Emerging Infectious Diseases that MERS’ CFR in South Korea (22 percent) is fully half that seen in Saudi Arabia (44 percent).

This infographic about Brownstein and Majumder’s MERS paper gives a snapshot of the data the analyzed, and what they think those data mean:

So, what’s your digital phenotype?

Ideally, we’re all supposed to see our doctor once a year for a checkup. It’s an opportunity to see how we’re doing from a health perspective, address any concerns or issues that we may have and catch any emerging issues before they become true problems.

But those visits are really only one-time, infrequent snapshots of health. They don’t give a full view of how we’re doing or feeling.

Now, think for a moment about how often you post something to Facebook or Twitter. Do you post anything about whether you’re feeling ill or down, or haven’t slept well? Ever share how far you ran, the route you biked or your number of steps for the day?

Every time you do, you’re creating a data point—another snapshot—about your health. Put those data points together, and what starts to emerge is a rich view of your health, much richer than one based on the records of your occasional medical visit.

As John Brownstein, PhD—director of the Computational Epidemiology Group (CEG) in Boston Children’s Hospital’s Computational Health Informatics Program and the hospital’s new Chief Innovation Officer—explains in this episode of the Harvard Medical School (HMS) Labcast (click the image above to hear it), this view has a name: your digital phenotype.

Detecting Ebola within minutes: A treatment and containment game changer


Tests for detecting Ebola in the blood can take anywhere from 12 hours to four days to yield results. But a recent study published in The Lancet reveals that a new point-of-care test can accurately determine results in mere minutes—another step toward potentially controlling the spread of Ebola.

Nira Pollock, MD, PhD, senior author of the paper and associate medical director of the Infectious Diseases Diagnostic Laboratory at Boston Children’s Hospital, along with researchers from Harvard Medical School and Partners In Health, showed that a commercially developed rapid diagnostic test (RDT), called the Corgenix ReEBOV Antigen Rapid Test kit, was as sensitive as a conventional laboratory-based method used for clinical testing during the recent outbreak in Sierra Leone.

Targeting inflammation in sickle cell disease with fatty acids

Painful, tissue-damaging vaso-occlusive crises (a.k.a. pain crises) are one of the key clinical concerns in sickle cell disease (SCD). The characteristic C-shaped red blood cells of SCD become jammed in capillaries, starving tissues of oxygen and triggering searing pain. Over a patient’s life, these repeated rounds of oxygen deprivation (ischemia) can take a heavy toll on multiple organs.

There’s some debate as to why these crises take place—is the sickled cell’s shape and rigidity at fault, or are the blood vessels chronically inflamed and more prone to blockage? Either way, doctors can currently do little to treat vaso-occlusive crises, and nothing to prevent them.

The inflammation view, however, is leading some researchers to ask whether omega-3 fatty acids—which can alleviate inflammation—might be part of the solution. A recent mouse study in the journal Haematologica, led by Mark Puder, MD, PhD, of Boston Children’s Vascular Biology Program, and Carlo Brugnara, MD, of the hospital’s Department of Laboratory Medicine reveals some molecular clues and suggests that human trials of omega-3s might be a good next step.

Early adversity and the brain: Bangladeshi children may provide lessons

neuroimaging adversity Bangladesh
Children from the neighborhood around the neuroimaging lab

Dhaka, Bangladesh, is a megacity, one of the world’s fastest growing. By 2025, the U.N. predicts, Dhaka will be home to more than 20 million people as rural migrants swell its population. Many residents live in extreme poverty, crowded into dense, hot, chaotic slums with open sewers and corrugated housing.

While traditional global health programs have focused on curbing infectious disease, low-resource settings like Dhaka are also coming to be seen as “living laboratories” for investigating how adversity affects children’s brain development. Last year, the Bill & Melinda Gates Foundation awarded a two-year, $2.5 million grant to Charles Nelson, PhD, to bring the first fully equipped neuroimaging facility to Bangladesh.
