From aerospace to the OR: 3D modeling improves surgical planning by revealing details of patients’ hearts
One of the most important tools for complex heart surgeries at Boston Children’s isn’t even in the operating room. For years, heart surgeons couldn’t see the complete extent of a patient’s condition until a procedure started, forcing them to rely on experience, diagnostic imaging, and other information to plan surgery. Now, 3D modeling allows them ... Read More about From aerospace to the OR: 3D modeling improves surgical planning by revealing details of patients’ hearts
Bedside tech predicts newborns’ outcomes after therapeutic hypothermia
Hypoxic-ischemic encephalopathy (HIE), brain injury caused by oxygen deprivation around birth, is a common cause of admission to the neonatal intensive care unit. Therapeutic hypothermia is now becoming the standard treatment to minimize brain injury; cooling the newborn’s head or whole body for three days slows cellular metabolism and allows brain cells to avoid and ...

The sooner the better: An argument for fetal MRI before 16 weeks
To date, fetal magnetic resonance imaging (MRI) has been limited to the mid-second or the third trimester of pregnancy. This timing has been based on the belief that MRIs performed too early couldn’t produce diagnostic images because of the small fetal size and normal fetal motion. In addition, although practice guidelines indicate that first-trimester imaging ... Read More about The sooner the better: An argument for fetal MRI before 16 weeks
Fetal brain imaging predicts neurodevelopment of babies with congenital heart disease
Children with congenital heart disease (CHD) often have neurodevelopmental impairment. Until fairly recently, this was thought to stem from complications of cardiac surgery or reduced oxygen supply to the brain due to the heart defect. Now we know that some babies with CHD have impaired brain development in utero because of low oxygen supply to ...

Sound sleep, sound mind: The importance of sleep for preteens’ developing brains
When your preteen doesn’t get enough sound sleep, some of the signs, like crankiness, are obvious. But some of the effects are more subtle. A large, first-of-its-kind study from Boston Children’s Hospital now shows that too little or poor-quality sleep may prevent the brain from developing strong, efficient connections. “Early adolescence is a critical time ...

What makes the Delta variant of COVID-19 so contagious?
The Delta variant of SARS-CoV-2 has swept the planet, becoming the dominant variant within just a few months. A new study from Boston Children’s Hospital, published in Science, explains why Delta spreads so easily and infects people so quickly. It also suggests a more targeted strategy for developing next-generation COVID-19 vaccines and treatments. Last spring, ... Read More about What makes the Delta variant of COVID-19 so contagious?
Regular physical activity linked to more ‘fit’ preteen brains
We know exercise has many health benefits. A new study from Boston Children’s Hospital adds another benefit: Physical activity appears to help organize children’s developing brains. The study, led by Dr. Caterina Stamoulis, analyzed brain imaging data from nearly 6,000 9- and 10-year-olds. It found that physical activity was associated with more efficiently organized, robust, ... Read More about Regular physical activity linked to more ‘fit’ preteen brains
Sturdier spikes may explain SARS-CoV-2 variants’ faster spread
The fast-spreading U.K., South Africa, and Brazil variants are raising concerns and questions about whether current COVID-19 vaccines will protect against them. A structural biology study led by Bing Chen, PhD, at Boston Children’s Hospital now reveals how the D614G mutation — carried by all three variants — makes SARS-CoV-2 spread faster. Key takeaways: The main ... Read More about Sturdier spikes may explain SARS-CoV-2 variants’ faster spread
At the forefront of kidney stone removal: Innovative approaches transform patient care
No longer considered just an adult problem, kidney stones increasingly affect children as well. The majority of children who cannot pass stones on their own can be treated with minimally invasive approaches such as extracorporeal shock wave lithotripsy, ureteroscopy, percutaneous nephrolithotomy, laparoscopic and robotic approaches and, rarely, open surgery. Now, two recent innovations provide additional ... Read More about At the forefront of kidney stone removal: Innovative approaches transform patient care
Capturing SARS-CoV-2’s shape-shifting spike protein
The rod-like spike proteins on the surface of SARS CoV-2 are the tip of the spear of the COVID-19 pandemic. The spikes bind to human cells via the ACE2 receptor and then dramatically change shape. They jack-knife, folding in on themselves to fuse their own membrane with the membrane of our cells. And that opens ... Read More about Capturing SARS-CoV-2’s shape-shifting spike protein
