MedicalResearch.com: What is the background for this study?
Response: Our research group had previously studied how oncology drugs are approved in these two previous papers listed below. One is focused on the time delay trade-off from surrogate endpoints (i.e. response rate and progression-free survival) over definite endpoints (i.e. overall survival and quality of life). The other is focused on how promising the response rate of a drug candidate have to be to be considered for oncology drug approval.

MedicalResearch.com: What is the background for this study? Would you briefly explain what is meant by atopic dermatitis?
Response: Chronic allergic itch is a worldwide problem that leads to substantial health expenses,but what causes this universal urge to scratch remains elusive in chronic allergic itch. Atopic dermatitis is a common allergic skin disease that often associated with extremely itchy and inflamed skin.
In our study, we showed, for the first time, a molecular pathway that is involved in chronic allergic itch as we identified an endogenous mediator (periostin) and a new role for its sensory neuron receptor, the integrin αVβ3, which drives the excitability and transmission of itch signal to the spinal cord.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: I've been working with Coady Wing and Ashley Bradford on a few different studies of the effects of recreational marijuana laws on drug and alcohol use.
Soon after EVALI became a major issue, the prevailing theory from the CDC and others was that EVALI was caused by the use of vitamin E acetate in illegal THC vaping products.
Our group read about this and we thought about some of the things that often happen in black markets for illegal drugs. For instance, during the alcohol prohibition era, bootleg alcohol producers often made and sold alcohol products that were not that safe to drink. In more recent years, there are cases where black market sellers of illegal drugs like heroin try to increase profit margins by adding other substances, which can be harmful.
We thought that maybe something like that could be happening in EVALI. Perhaps people in states where recreational marijuana is legal tended to purchase marijuana products from the legal market and the legal market was not selling any marijuana vaping products that included vitamin E acetate.

MedicalResearch.com: What is the background for this study? What are the main findings?
Response: Children in foster care have high rates of medical problems including chronic diseases. There is less known about the differences in mortality for children in foster care.
Looking at national data from 2003 to 2016, this study finds that children (ages 1 to 18) in foster care have higher mortality compared to children in the general population and that the difference in mortality has increased over time.

MedicalResearch.com: What is the background for this study?
Response: As some health care systems approach collapse, a pressing need exists for tools modeling the capacity of acute and critical care systems during the COVID-19 pandemic.
We developed an online tool to estimate the maximum number of COVID-19 cases that could be managed per day within the catchment area served by a health care system, given acute and critical care resource availability.
The COVID-19 Acute and Intensive Care Resource Tool (CAIC-RT) is open access and available at
