Injected microbubbles could be a safe way to deliver emergency oxygen
For years, researchers and clinicians have been trying to find a way to rapidly deliver oxygen to patients when traditional means of oxygenation are difficult or ineffective during critical moments of cardiac or respiratory arrest. Sometimes, hypoxemia caused by airway obstruction or lung disease can be so severe that methods to boost low-oxygen levels (including ...

From ‘hit to vial’: Discovery and optimization of a promising vaccine adjuvant
Many vaccines are only partially effective, have waning efficacy, or do not work well in the very young or the very old. For more than a decade, Ofer Levy, MD, PhD, and David Dowling, PhD, in the Precision Vaccines Program at Boston Children’s Hospital, have tried improving vaccines by adding compounds known as adjuvants to ...

The journey to a treatment for hereditary spastic paraplegia
In 2016, Darius Ebrahimi-Fakhari, MD, PhD, a neurology fellow at Boston Children’s Hospital, met two little girls with spasticity and decreased muscle tone in their legs, which affected their walking. Both girls, Robbie Edwards and Molly Duffy, had been diagnosed with hereditary spastic paraplegia (HSP), a group of more than 80 genetic conditions. Untreated, the ...

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 ...

Nanobodies from alpacas could steer immune attacks on influenza
While conventional flu vaccines are designed to anticipate the influenza strains projected to dominate in the next flu season, they’re only partially effective. And while antiviral drugs are available to treat active flu cases, the body quickly clears them, requiring high, frequent doses. Coupling one existing flu drug with a special ingredient from alpacas, the ... Read More about Nanobodies from alpacas could steer immune attacks on influenza
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,” ...

Going out of the box to tackle pancreatic cancer
Pancreatic cancers are deadly and hard to treat, in part because they are so often detected at an advanced stage; overall five-year survival rates are about 11 percent. Two separate labs at Boston Children’s Hospital took out-of-the-box approaches to this difficult cancer, and both uncovered some very promising leads. Wiping out pancreatic tumors’ immune defense ...

Why do so many dementia treatments fail? Questioning mouse models of tau accumulation
To date, the search for effective treatments for dementia has yielded only disappointments. Many recent drug candidates target the tau protein, which aggregates and forms tangles in patients’ brain tissue and is involved in 75 percent of all dementias. While tau-targeting drugs have looked promising in mouse models, they’ve failed in clinical trials. A recent ... Read More about Why do so many dementia treatments fail?

‘On fire’ with sJIA: When arthritis is much more than joint pain
Georgia is finally living her best life. Her toddler years were challenging: At 15 months old, a series of high fevers landed her at Boston Children’s Hospital for two weeks. After many rounds of tests looking for infection and a bone marrow biopsy to rule out cancer, she was diagnosed with systemic juvenile idiopathic arthritis ...
