Missed signals? A new way we vary from each other biologically
Genetics has made huge strides over the past 20 years, from the sequencing of the human genome to a growing understanding of factors that turn genes on and off, namely transcription factors and the DNA “enhancer” sequences they bind to. New research from Boston Children’s Hospital introduces another previously unknown layer of human genetics. It ... Read More about Missed signals? A new way we vary from each other biologically
Rising global temperatures tied to rising antibiotic resistance
A new data analysis suggests that two rising public health threats — climate change and antibiotic resistance — are related. The study, spanning 2000 to 2016, doesn’t establish cause and effect. But its findings, in the journal Eurosurveillance, suggest that rising global temperatures could be helping to fuel increases in antibiotic-resistant bacteria. Key takeaway Countries ...

Precision chemo-immunotherapy for pancreatic cancer?
Pancreatic cancer is highly lethal and in great need of better treatments. Only about 10 percent of patients remain alive five years after diagnosis. In a new study, researchers in the lab of Marsha Moses, PhD, at Boston Children’s Hospital offer a glimmer of hope. Key takeaway An antibody-drug combination effectively targeted, penetrated, and shrank ... Read More about Precision chemo-immunotherapy for pancreatic cancer?
Why do some children exposed to the coronavirus go on to develop MIS-C?
Most children exposed to the SARS-CoV-2 coronavirus have few or no symptoms. But a small number become sick enough to go to the hospital. And a tiny handful develop a severe inflammatory illness called multisystem inflammatory syndrome (MIS-C), often weeks after initial exposure to the virus. Why? A team at Boston Children’s Hospital is using ... Read More about Why do some children exposed to the coronavirus go on to develop MIS-C?
Remdesivir: What to know about the first drug approved to treat COVID-19
In late October, the U.S. Food and Drug Administration (FDA) officially approved the antiviral drug remdesivir (Veklury) for COVID-19. The approval has been controversial, with many scientists questioning the strength of the evidence and proposing that the drug undergo further clinical trials before receiving full FDA approval . What does this mean for children who ... Read More about Remdesivir: What to know about the first drug approved to treat COVID-19
Too many blood cells: Probing a blood cancer’s genetic origins
At age 7, Meredith Shah began having debilitating migraine headaches. “I would have trouble seeing and shapes were blurry,” she recalls. “It was really painful.” Over time, the frequency and intensity of the headaches escalated. Her parents, Heidi and Nil, sought the help of multiple specialists. But they received few answers, other than an indication ...

The tiny choroid plexus protects the prenatal brain — but may also pass on inflammation from the mother
Floating in fluid deep in the brain are small, little-understood fronds of tissue. Two new studies reveal that these miniature organs are a hotbed of immune system activity. This activity may protect the developing brain from infections and other insults — but may also contribute to neurodevelopmental disorders like autism. Key takeaway This pioneering work ...

Coordinated care and research for genetic cardiovascular disorders
Genetic cardiovascular disease in children sometimes comes to light in a crisis — a sudden collapse, sudden breathing difficulty, a sudden death in the family. Or it may be part of a diverse collection of symptoms, mostly having nothing to do with the heart. Sometimes it is picked up incidentally. “From an incidental ECG finding ...

Affordable Care Act eases health care costs for families with children, study finds
On November 10, the U.S. Supreme Court will hear arguments on a case challenging the Affordable Care Act. With the ACA’s future in question, a study from Boston Children’s Hospital provides a reminder that the law has substantially reduced health care expenses for many families with children — particularly low- and middle-income families. Key takeaway ... Read More about Affordable Care Act eases health care costs for families with children, study finds
A diabetes drug with a potential side benefit: Reduced COVID-19 mortality
In 2006, the Food and Drug Administration approved the drug sitagliptin to lower blood sugar in type 2 diabetes. Now, a multicenter observational study in Italy suggests the drug also cuts mortality in diabetic patients hospitalized with COVID-19 — by as much as half. Paolo Fiorina, MD, PhD, of Boston Children’s Hospital led the study, ... Read More about A diabetes drug with a potential side benefit: Reduced COVID-19 mortality
