Blood Stream Infection

Blood stream infections are conditions that result when the body is fighting a severe infection that has spread via the bloodstream.

Study to Investigate the Safety, Tolerability, and Pharmacokinetics of DSTA4637S in Participants With Staphylococcus Aureus Bacteremia Receiving Standard-of-Care (SOC) Antibiotics

The purpose of this study is to test the safety of DSTA4637S, an investigational drug, at different dose levels and to find out what effects, good or bad, DSTA4637S, has on you while treating the S. aureus infection in your blood. DSTA4637S will be given in addition to the antibiotics you are already receiving for your S. aureus infection.

DSTA4637S is an investigational antibiotic to treat serious infections caused by the bacteria S. aureus. DSTA4637S is an experimental drug, which means that the Food and Drug Administration (FDA) or other health authorities that regulate new drugs have not approved DSTA4637S for the treatment of S. aureus bacteremia, except for testing in clinical trials.

Neonatal Salivary Transcriptomics

The ability to monitor the health status of premature neonates for research purposes has long been limited by these infants' fragile medical conditions and small blood volumes. Advancements in salivary technology suggests that transcriptomic and proteomic salivary analysis is an innovative, highly informative, and noninvasive means to monitor this patient population, and correlate medical and neurodevelopmental outcomes with specific gene expression profiles. The purpose of this study is to use normally obtained and routinely discarded neonatal salivary samples to noninvasively generate transcriptomic and proteomic profiles of premature neonates. Saliva will be collected serially from infants born greater to or equal to 24 weeks' gestation who are admitted to the Tufts Medical Center NICU or MIU. Our research is focused on two areas of neonatal physiology and pathology . The first area of interest involves monitoring infants during the learning process of oral feeding. Our second area of interest involves feeding intolerance and gastrointestinal disease (i.e. necrotizing enterocolitis) and infection. Healthy term neonates will serve as comparative controls. Both short and long term medical and neurological (up to 24 months corrected age) outcomes, will be correlated with the distinct gene expression profiles in order to better understand neonatal physiology, pathology and overall health status.
