Playing the long game: An exciting discovery in telomere disease
Each time our cells divide, the protective caps that keep our chromosomes from fraying, called telomeres, lose a bit of their DNA. Telomeres shorten steadily as we age, but in certain medical conditions like dyskeratosis congenita, the process is accelerated. “Your telomeres determine your lifeline; how long they are determines how old your body is,” ...

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
Years in the making: Team performs successful fetal intervention for VOGM
On an ordinary Wednesday in March, a team of specialists from two institutions made the extraordinary happen: a first-of-its-kind intervention for a rare, life-threatening type of blood vessel anomaly called a vein of Galen malformation (VOGM) — performed in utero. The ultrasound-guided embolization involves deploying tiny metal coils into the affected vein via a microcatheter ...

Immune biomarkers predicted COVID-19 severity and could help in future pandemics
Why did some people fall critically ill from COVID-19 and others not? In May 2020, as COVID-19 swept the world, Boston Children’s Hospital helped launch a national, NIAID-funded study called IMPACC (IMmunoPhenotyping Assessment in a COVID-19 Cohort). Taking a “systems immunology” approach, the goal was to document the virus’s impact on the immune system in ...

Advancing mother-child health globally: Grace Chan MD, MPH, PhD
First in an ongoing series profiling researchers at Boston Children’s Hospital. Globally, five million children die annually before the age of 5. Forty percent of these deaths are in the first month — and many are preventable. Grace Chan, MD, MPH, PhD, finds these numbers unacceptable. They contrast starkly with U.S. medicine, including at Boston ... Read More about Advancing mother-child health globally: Grace Chan MD, MPH, PhD
Another angle on Alzheimer’s: CSF, proteomics, and metabolic enzymes
Currently there are no objective, easily assessed diagnostic markers for Alzheimer’s disease, and no good therapeutic options. Taking an agnostic approach, proteomics expert Hanno Steen, PhD, and neurobiologist Judith Steen, PhD, who share a lab at Boston Children’s Hospital, teamed up to analyze proteomics data from the cerebrospinal fluid (CSF) that bathes the brain, combining ...

BMI and the adolescent brain: A concerning connection
We all know that obesity is a growing epidemic in children and adults. A large national study now finds that preteens carrying excess weight have notable differences in cognitive performance, brain structures, and brain circuitry when compared to preteens with normal body-mass index (BMI). Funded by the National Science Foundation’s Harnessing the Data Revolution initiative, ... Read More about BMI and the adolescent brain: A concerning connection
(Virtually) visiting the home to help control childhood asthma
Many children have difficulty taking their asthma medicine on a regular basis. Sometimes it’s a matter of feeling well and deciding not to take the medication; other times, it’s simply forgetting. But some children also don’t know how to properly use an asthma inhaler, or they can’t access their medicine in the first place. A ...

Could we make blood anywhere in the body?
Our bodies make blood in a specialized niche — a “nursery” within our bone marrow that nurtures blood stem cells so they can replicate and make different kinds of blood cells. The lab of Leonard Zon, MD, has even shown how blood stem cells, once they settle in the niche, are “cuddled” by nearby cells. ... Read More about Could we make blood anywhere in the body?
A new cancer mechanism: Failed cellular housekeeping
Cancer can stem from mutations in many different genes. New research from Boston Children’s Hospital and Dana-Farber Cancer Institute pinpoints a gene that, when mutated, causes cancer through a mechanism not before seen: Inability of cells to dispose of their trash, namely defective strands of RNA. This mechanism appears to cut across many different malignancies, ... Read More about A new cancer mechanism: Failed cellular housekeeping
