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.
“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).
By the time oral and maxillofacial surgeon Salim Afshar, DMD, MD, was 29 years old, he had acquired medical and dental degrees from Harvard Medical School and Harvard School of Dental Medicine. Ever since, he has dedicated his life to community service and his surgical skills to improving community and global health.
An impassioned humanitarian, Afshar serves as one of the faculty members in the Program in Global Surgery and Social Change at Harvard Medical School. As an entrepreneur and innovator, he’s co-founded a health care software company that enables providers to engage and manage patients and their families around complex episodes of care.
“My whole orientation in life is around being of service — service to my patients, service to my community and service to my family,” Afshar says.

Affordable home dialysis, a device to triage heart murmurs, a cardiopulmonary support enhancer, a novel technology to treat septic shock and a better system for studying neurological function. Which of these ideas will catch fire?
The 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.
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.
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.
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.
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.
