Researchers from Children's Hospital of Philadelphia (CHOP) and Children's Hospital Colorado have found that better control of chronic eosinophilic esophagitis (EoE)-associated inflammation during childhood leads to less stiffening of the esophagus, resulting in fewer disease complications. Using Endoluminal functional imaging (FLIP), the study team suggests this could be a key marker for assessing disease severity and progression. The findings were published online today by the journal Gastroenterology.

One of the biggest challenges in cancer treatment is that certain cancers reappear after chemotherapy—and an aggressive type of blood cancer called acute myeloid leukemia (AML) is notorious for this.

New research, led by Queen Mary University and published in the journal Clinical Psychological Science, has revealed that highly sensitive people (HSP) are more likely to experience mental health problems compared to individuals who are less sensitive.
