Naloxone on demand: Shining a light to reverse opioid overdose
Overdose deaths from fentanyl and other opioids are at record highs in the U.S. Naloxone, if delivered soon after an overdose, is proven to be life-saving. It binds to the same brain receptors that opioids use, thereby blocking opioids’ effects. A naloxone nasal spray (Narcan) is now available over the counter, but there are still problems ...

Gold particles and light could melt venous malformations away
Venous malformations — tissues made up largely of abnormally shaped veins — are often difficult to treat, especially when located in sensitive areas like the eyes, face, and genitourinary organs. In the worst cases, the lesions are disfiguring and can crush or obstruct surrounding tissues, cause bleeding and clotting, interfere with breathing or vision, or ...

A new approach to C. diff? Targeting the inflammation, not the bacteria
Clostridium difficile (C. diff) intestinal infections can cause severe, debilitating diarrhea in patients who are hospitalized or on immunosuppressive therapies. The infections can be very hard to eradicate, roaring back when patients try to taper their antibiotics. Many people wind up on antibiotics for months and can become resistant to three or more of them. ... Read More about A new approach to C. diff? Targeting the inflammation, not the bacteria

Could we intervene in Huntington’s disease before symptoms appear?
Huntington’s disease is the most common single-gene neurodegenerative disorder and is characterized by motor and cognitive deficits and psychiatric symptoms. Work led by Beth Stevens, PhD, and Dan Wilton, PhD, in the Department of Neurology at Boston Children’s Hospital, now shows that the disease process begins well before symptoms appear. That raises the possibility of ... Read More about Could we intervene in Huntington’s disease before symptoms appear?

Toddlers diagnosed with autism should be reevaluated over time
Parents whose child has been diagnosed with autism spectrum disorder (ASD) may feel it’s a lifelong label. But a new study offers hope: It found that 37 percent of children diagnosed as toddlers no longer met criteria for autism when they reached early school age. Findings were published October 2 in JAMA Pediatrics. Study leader ... Read More about Toddlers diagnosed with autism should be reevaluated over time
Bringing equity to genomic sequencing in newborns: BabySeq 2.0
Today, nearly 900 disorders caused by a single gene are known to be treatable. Yet the recommended “heel stick” testing for newborns only covers about 60 inherited, treatable disorders, and many individual states screen for fewer. What if newborns could instead have their entire genome sequenced at birth, with the results shared and acted on ... Read More about Bringing equity to genomic sequencing in newborns: BabySeq 2.0
This two-handed robot goes deep into the brain
Robots have become common partners in the OR, enabling surgeons to operate through small incisions and manipulate tools endoscopically, avoiding invasive open surgery. But in neurosurgery, robots’ capabilities have been more limited. While they can assist with relatively simple procedures like inserting an electrode, more invasive and complex operations like removing a tumor still require ...

Making immunotherapy safe for AML
Acute myeloid leukemia (AML), the second most common leukemia in children, is hard to treat and has a five-year survival rate of just 65 to 70 percent, according to the American Cancer Society. While immunotherapies like monoclonal antibodies or CAR T-cell therapy are effective for certain blood cancers, they have not been possible in AML ...

EEG markers in early life could help predict and diagnose anxiety
Anxiety disorders are the most common mental health problem among children and adolescents and are a risk factor for adult disorders. Stress is a big factor — at home, at school, and from external factors like COVID-19 and climate change. But some children may be innately more susceptible to anxiety. New research at Boston Children’s ... Read More about EEG markers in early life could help predict and diagnose anxiety

Pioneering trial offers hope for late treatment of ‘lazy eye’
In children with amblyopia or “lazy eye,” one eye is weaker than the other for any of a number of reasons. It may not focus as well, it may be misaligned due to strabismus, or its vision may be obstructed by a cataract or a droopy eyelid. As a result, the brain starts to favor ...
