Sex steroid treatment changes HDL cholesterol levels in transgender youth
In an important study in transgender youth, researchers at Boston Children’s Hospital and colleagues have discovered that HDL cholesterol levels change within six months after starting gender-affirming medical treatment. HDL levels dropped an average 7 points in transmasculine patients and they rose by about 11 points in transfeminine youth. The HDL shifts do not indicate ... Read More
Piecing together the preterm infant microbiome
The human microbiome — the collection of microbes living in the gut — is now recognized as an important contributor to health and disease. The environment, the host, and microbe-microbe interactions are all likely to shape the microbiome’s dynamics, but the unique roles of each are not well understood. Now, a Boston Children’s Hospital infectious ... Read More
Can we prevent leukemia in patients with Shwachman-Diamond syndrome?
Anna Nazarenko doesn’t see herself as sick. The strong-willed, spunky 6-year-old loves to dance and ski, and spent much of April Fool’s day pranking her parents. Aside from the enzymes she takes to help digest her food, you wouldn’t know that she has Shwachman-Diamond syndrome (SDS). The rare, inherited type of bone marrow failure has ... Read More
Diversifying therapeutic antibodies: From one, come many with potential different uses
A new method for producing antibodies against disease could result in a wider variety of drugs for infectious diseases, immune disease, and even cancer. The immune system naturally produces enormous varieties of antibodies to fight diseases. Therapeutic antibodies — antibodies created against specific therapeutic targets — have been used for decades to either rev up ... Read More
Game-changing surgical procedure results in zero-percent TEF re-recurrence rate
A tracheaesophageal fistula (TEF) is a congenital defect in which an abnormal connection forms between a child’s esophagus and trachea. It often occurs with esophageal atresia. Even after surgical repair, TEFs recur in about 10 to 15 percent of infants and children. They rarely close spontaneously and typically require surgical or endoscopic intervention. Key takeaways: ...

Sturdier spikes may explain SARS-CoV-2 variants’ faster spread
The fast-spreading U.K., South Africa, and Brazil variants are raising concerns and questions about whether current COVID-19 vaccines will protect against them. A structural biology study led by Bing Chen, PhD, at Boston Children’s Hospital now reveals how the D614G mutation — carried by all three variants — makes SARS-CoV-2 spread faster. Key takeaways: The main ... Read More
