“The fact that we were able to predict influenza outbreaks faster than China’s national surveillance programs really shows the capacity for everyday, wearable digital health devices to track the spread of disease at the population level,” says the study’s lead author Yulin Hswen, who is a research fellow in Boston Children’s Computational Epidemiology Group and a doctoral candidate at the Harvard T. H. Chan School of Public Health.
China has 620 million mobile internet users who can theoretically access the standalone Thermia application from any computer, smartphone or even the Amazon Alexa assistant.
Although the Boston Children’s team has previously demonstrated that social media can be used to track disease, this is the first time they’ve shown that outbreaks can be predicted through an integrated wearable device and online tool. …
“It’s a brutal disease; there’s just no other way to describe DIPG,” says Steve Czech. “And what’s crazy is that there aren’t many treatment options because it’s such a rare, orphan disease.”
Czech’s son, Mikey, was diagnosed with a diffuse intrinsic pontine glioma (DIPG) on Jan. 6, 2008. It was Mikey’s 11th birthday. The fast growing and difficult-to-treat brainstem tumors are diagnosed in approximately 300 children in the U.S. each year.
Sadly, the virtually incurable disease comes with a poor prognosis for most children. The location of DIPG tumors in the brainstem — which controls many of the body’s involuntary functions, such as breathing — has posed a huge challenge to successful treatment thus far.
“Typically, they give kids about nine months,” says Czech. “Our lives changed forever the day that Mikey was diagnosed.” …
Recently, the annual ASPHO (American Society for Pediatric Hematology/Oncology) meeting brought together more than 1,100 pediatric hematologists and oncologists, including a team from the Dana-Farber/Boston Children’s Cancers and Blood Disorders Center. Some of the delegates from Dana-Farber/Boston Children’s included:
Amy Billett, MD: president of ASPHO, director of safety and quality and a hematologist/oncologist at Dana Farber/Boston Children’s
“Without iron, life itself wouldn’t be feasible,” says Barry Paw, MD, PhD. “Iron transport is very important because of the role it plays in oxygen transport in blood, in key metabolic processes and in DNA replication.”
Although iron is crucial to many aspects of health, it needs the help of the body’s iron-transporting proteins. Which is why new findings reported in Science could impact a whole slew of iron disorders, ranging from iron-deficiency anemia to iron-overload liver disease. The team has discovered that a small molecule found naturally in Japanese cypress tree leaves, hinokitiol, can transport iron to overcome iron disorders in animals.
The multi-institutional research team is from the University of Illinois, Dana-Farber/Boston Children’s Cancer and Blood Disorders Center, Brigham and Women’s Hospital and Northeastern University. Paw, co-senior author on the new paper and a physician at Dana-Farber/Boston Children’s, and members of his lab demonstrated that hinokitiol can successfully reverse iron deficiency and iron overload in zebrafish disease models.
“Amazingly, we observed in zebrafish that hinokitiol can bind and transport iron inside or out of cell membranes to where it is needed most,” says Paw.
This gives hinokitiol big therapeutic potential. …
In the U.S., about one in 100 people have some form of epilepsy. A third of those people have seizures that cannot be controlled with drugs, eventually requiring surgery to remove the area of their brain tissue that is triggering seizure activity.
“If you can identify and surgically remove the entire epileptogenic zone, you will have a patient who is seizure-free,” says Christos Papadelis, PhD, who leads the Boston Children’s Brain Dynamics Laboratory in the Division of Newborn Medicine and is an assistant professor in pediatrics at Harvard Medical School.
At present, however, these surgeries are not always successful. Current diagnostics lack the ability to determine precisely which parts of an individual’s brain are inducing his or her seizures, called the epileptogenic zone. In addition, robust biomarkers for the epileptogenic zone have been poorly established.
But now, a team at Boston Children’s Hospital is doing research to improve pre-surgical pinpointing of the brain’s epileptogenic zone. They are using a newly-established biomarker for epilepsy — fast brain waves called high-frequency oscillations (HFOs) — that can be detected non-invasively using scalp electroencephalography (EEG) and magnetoencephalography (MEG). …
In 1962, the Harvard School of Public Health made a critical loan to Boston Children’s Hospital: the Harvard hyperbaric chamber. It established a new approach to pediatric heart surgery at Boston Children’s.
For many children — including a premature infant named Janet, born in 1964 with a heart murmur — the hyperbaric chamber would prove to be life-saving.
At that time, before the invention of the heart-lung bypass machine, hyperbaric chambers offered a way to operate on infants more safely. That’s because hyperbaric oxygenation, coupled with the effects of increased pressure on the respiratory system, seemed to give infants a better chance of surviving heart surgery. …
Now, 2017: Today, Orkin is associate chief of Hematology/Oncology and chairman of Pediatric Oncology at Dana-Farber/Boston Children’s Cancer and Blood Disorders Center (DF/BC). In this photo, he examines a rendering of a gene regulatory molecule’s structure. Orkin’s lab investigates gene regulation of stem cell development, genetic vulnerabilities to cancer and gene and other therapies for treating hemoglobin disorders. …
Today, stories of polio may seem like echoes from far-away history to those born after 1979, the year that polio was eradicated in the U.S. Since then, it has been customary for children to receive four doses of the polio vaccine to protect them from ever contracting the terrifying disease also known as “infantile paralysis.”
Polio, however, still afflicts people in some areas of the world today. It causes muscle wasting and — in the most severe cases — can completely rob a person of his or her ability to move or breathe, resulting in death.
In the U.S., research efforts to create a polio vaccine lasted much of the 20th century. Although the virus was thriving and spreading among people, researchers repeatedly failed at getting poliovirus to survive in culture.
Then, one of the most crucial breaks in the fight against polio occurred in a Boston Children’s Hospital laboratory in 1949, during the heyday of polio outbreaks. …
Childhood cancers are rare and account for about one percent of U.S. cancer diagnoses. They differ from adult tumors in that they often arise from many more diverse kinds of cells, including embryonal tissues, sex-cord stromal cells of the ovary or testis, the brain’s neural and glial cells and more.
Yet although improved tumor detection and treatment have increased survival rates for many different cancer subtypes, more than 1,900 children across the U.S. still lose their battle each year.
A new dataset — comprising the genomic profiles of a huge array of pediatric tumors — could help change that. …
Residents of Arkansas have been under siege by a viral threat that is typically preventable through vaccination. Since August 2016, more than 2,000 people have been stricken with mumps, an infection of the major salivary glands that causes uncomfortable facial swelling.
The disease is highly contagious but can usually be prevented by making sure that children (or adults) have had two doses of the measles-mumps-rubella (MMR) vaccine. But strangely, about 70 percent of people in Arkansas who got sick with mumps reported that they had received their two doses of the MMR vaccine.
