NCT04826991
Wells and Enteric Disease Transmission
Approximately 40 million people in the US are served by private, and frequently untreated, wells. Our best estimate is that 1.3 million cases of gastrointestinal illnesses (GI) per year are attributed to consuming water from untreated private wells in the US, but in reality, there are no robust epidemiological data that can be used to estimate cases of GI attributable to these sources. We propose the first randomized controlled trial (RCT) to estimate the burden of GI associated with private well water. We will test if household treatment of private well water by ultraviolet light (UV) vs. sham (inactive UV device) decreases the incidence of GI in children under 5. We will also examine the presence of viral, bacterial, and protozoan pathogens in stool and well water from participants. These data will fill a knowledge gap on sporadic GI associated with federally-unregulated private water supplies in the US.

Fish Oil in pREgnancY for Personalized Prevention of Early Childhood Asthma
The overall aim of the study is to develop a nutritional preventive fish oil supplementation strategy in pregnancy for early childhood asthma/persistent wheeze during the first three years of life as we hypothesize that both supplementations in higher doses than recommended could reduce the risk of disease development.
