Study identifies distinct sub-types of aggressive tumours to allow for targeted treatment

A new study led by clinician-scientists from the National Cancer Centre Singapore (NCCS), with collaborators from research institutions worldwide, has found that angiosarcomas have unique genomic and immune profiles which allow them to be classified into three different subtypes. With this new and improved classification system, patients can be treated using a personalised-medicine approach and it will encourage the development of novel treatments.

Common diabetes drug may trigger rare complications for COVID-19 patients

Diabetes is a known risk factor for morbidity and mortality related to COVID-19. In diabetes patients, rare but severe complications, like the potentially lethal condition diabetic ketoacidosis (DKA), can arise when illness or certain conditions prevent cells from receiving enough glucose to fuel their functioning. An uptick in a particular type of DKA called euDKA at Brigham and Women's Hospital during the COVID-19 pandemic has led researchers to hypothesize that diabetes patients on glucose-lowering drugs may be at increased risk for euDKA when they contract COVID-19. The observational case series was published in The American Association of Clinical Endocrinologists Clinical Case Reports.
