2 Clinical Trials for Various Conditions
The purpose of this study is to measure oil production of the face, facial properties, and gut bacteria in people being given oral probiotics. Probiotic supplements contain active cultures of bacteria that are thought to be beneficial to human health.The investigators want to find out if probiotics taken by mouth alter the bacteria in subject's gut and subject's skin oil production compared to a placebo. This is a single blind study and subject may receive a probiotic or a placebo for the first half of the study and a placebo or a probiotic for the second half of the study. Subject will not know what was given to participants.
Premature infants are at risk for a variety of diseases, the investigators would like to learn more about why some premature babies are at higher risk and some are protected from these diseases. Scientists at UC Davis and other universities have developed new ways to measure the bacteria and a large number of small molecules in specimens of infant blood, urine, stomach fluid and poop and in mother's milk. These discoveries allow us to consider questions that were impossible to answer before these new techniques were developed. One such question is whether the bacteria in the poop of a premature baby can help us predict the baby's risk for developing infection or a common and serious disease of premature infants called necrotizing enterocolitis. A second question is whether the DNA of a premature baby (obtained from saliva with a q-tip) can predict higher risk for diseases of premature babies.
