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 ...

Preventing leukemia by preventing rogue blood cells from taking over
As we age, many of us acquire mutations that cause some of our blood stem cells to multiply faster than others, forming their own distinct populations or “clones.” This is known as clonal hematopoiesis. In some cases, a single clone originating from a single genetically altered or mutated stem cell can expand to comprise up ...

Diving deep on epilepsy genetics
When child neurologist Annapurna Poduri, MD, MPH finished her clinical epilepsy fellowship at Boston Children’s Hospital in 2004, she was struck to find that the genetic understanding of epilepsy had changed little in the decade since she started medical school. Many questions were unanswered — and some weren’t yet being asked. Existing treatments were still ... Read More about Diving deep on epilepsy genetics
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?
New research NETs a fresh angle for treating severe inflammation
As we’ve seen during the COVID-19 pandemic, serious infections sometimes trigger an excessive inflammatory reaction that does as much harm — or more — than the infection itself. New research at Boston Children’s Hospital and Brigham and Women’s Hospital suggests a potential way to block this hyperinflammation response by repurposing or modifying an existing drug. ...

Finding new targets for acute myeloid leukemia in children
Acute myeloid leukemia (AML) is the second most common leukemia diagnosed in children. It is hard to treat and can be fatal in some cases. While there have been some recent successes with genetically targeted therapies for adults, AML has different genetic features in children, and care has been slow to advance. “The state of ...

‘Human accelerated regions’: How they make our brains uniquely human
Starting when humans diverged from chimpanzees some 5 to 6 million years ago, we’ve evolved in our uniquely human fashion thanks to changes in our genome. And certain parts of the human genome, known as human accelerated regions or HARs, have evolved especially rapidly. Intriguing new work led by Christopher Walsh, MD, PhD, of Boston ...

Keeping kids emotionally healthy during COVID-19
Children and teens have suffered immensely during the COVID-19 pandemic. Changing school and family routines, isolation at home, illness or loss of a family member, stressed parents, and fear of the virus itself have hit kids hard. And sadly, the pandemic continues with the rise of new COVID-19 variants. Pediatric practices can play a role ... Read More about Keeping kids emotionally healthy during COVID-19
The adolescent mental health crisis: Bolstering primary care capabilities
The mental health crisis among children and teens shows no sign of abating, and COVID-19 has clearly made matters worse. A recent study found that suicide attempts and self-harm were among the few indications for hospitalization that didn’t drop during the first waves of the pandemic. On the contrary, the past year has seen a ... Read More about The adolescent mental health crisis: Bolstering primary care capabilities
Low-carb or low-fat? Study pinpoints better diet
Despite the popularity of low-carbohydrate diets, health experts have pushed low-fat diets for the past 50 years, citing saturated fat as the main health risk. As a result, grocery shelves are stocked with low-fat and fat-free foods, many of which are high in processed carbs. Drs. David Ludwig and Cara Ebbeling, who co-direct the New ...
