Finding ways to reduce the financial and social costs of pacemakers
As the number of complex heart operations has increased over the years, so have cases of postoperative heart block, a form of arrhythmia that often requires a pacemaker and more surgery. Heart block occurs when unseen conduction tissue — the cells and electrical signals that control the beating of a heart — is injured. It is a ...

Microvillus inclusion disease: From organoids to new treatments
Microvillus inclusion disease (MVID) is a rare type of congenital enteropathy in infants that causes devastating diarrhea and an inability to absorb food. Infants can lose liters of fluid a day, become severely dehydrated, and stop growing. There is no specific treatment. “Until about 10 years ago, 50 percent of kids with MVID would die ...

Exposing a tumor’s antigens to enhance immunotherapy
Successful immunotherapy for cancer involves activating a person’s own T cells to attack the tumor. But some tumors have a trick: They hide themselves from the immune system by preventing their antigens from being displayed, a necessary step in activating T cells. In new work published in Science, researchers in the Program in Cellular and ... Read More about Exposing a tumor’s antigens to enhance immunotherapy
Combining CAR-T cells and inhibitor drugs for high-risk neuroblastoma
Chimeric antigen receptor (CAR)-T cell therapy is a potent emerging weapon against cancer, altering patients’ T cells so they can better find and destroy tumor cells. But CAR-T cell therapy doesn’t work well in every cancer — including many cases of neuroblastoma, a cancer that begins in young children’s nerve tissue and can metastasize to ...

When diagnosis is just the first step: The Brain Gene Registry
Through advances in genetic sequencing, many children with rare, unidentified neurodevelopmental disorders are finally having their mysteries solved. But are they? “Once families receive results of genetic testing, that’s just the beginning of a new journey,” says Maya Chopra, MBBS, FRACP, an investigator with the Rosamund Stone Zander Translational Neuroscience Center at Boston Children’s Hospital. ...

Helping clinicians embrace family-centered rounds
If you’ve ever been hospitalized, you may have experienced this: groups of doctors coming in and talking about you like you’re not there or addressing you in a perfunctory manner, using medical jargon you don’t understand. Peggy Markle was taken aback when her son was hospitalized for a not-yet-defined condition in Washington and his care ... Read More about Helping clinicians embrace family-centered rounds
Ductus arteriosus stenting could help severely ill infants with pulmonary arterial hypertension
Treatment for infants who have severe pulmonary arterial hypertension (PAH) is sometimes limited. Because they haven’t physically matured, a procedure could increase the risk of serious complications, including failure of the heart’s right ventricle. A Boston Children’s Department of Cardiology study found an interventional therapy that’s potentially safe and suitable for those critically ill small infants: the placement of ...

Could a GI bug’s toxin curb hard-to-treat breast cancer?
Clostridium difficile can cause devastating inflammatory gastrointestinal infections, with much of the damage inflicted by a toxin the bug produces. But research from Boston Children’s Hospital suggests that the same toxin could also be a useful tool for curbing highly aggressive triple-negative breast cancers that don’t respond to chemotherapy. Min Dong, PhD, in the Department ... Read More about Could a GI bug’s toxin curb hard-to-treat breast cancer?
Researchers identify genes that could affect children’s bone growth
Many children anticipate reaching the next number on a measuring stick as they chart their growth. But measurements can be frustrating or stressful for children who have skeletal disorders that prevent bones from growing. Key findings Researchers used genome-wide association studies and CRISPR gene editing to see if alterations to cartilage cells, which are known ...

Engineered cartilage could turn the tide for patients with osteoarthritis
About one in seven adults live with degenerative joint disease, also known as osteoarthritis (OA). In recent years, as anterior cruciate ligament (ACL) injury and other joint injuries have become more common among adolescent athletes, a growing number of 20- and 30-somethings have joined the ranks of aging baby boomers living with chronic OA pain. ...
