Awarded Grants

Grand Challenges is a family of initiatives fostering innovation to solve key global health and development problems. Each initiative is an experiment in the use of challenges to focus innovation on making an impact. Individual challenges address some of the same problems, but from differing perspectives.

Preventing Preterm Birth in Zambia

Preventing Preterm Birth
1 Oct 2013

Jeffrey Stringer of the University of North Carolina Global Women’s Health group in the U.S. will oversee a team of Zambian and U.S. researchers in a prospective cohort study of 2,000 pregnant women over a three-year period in Lusaka, Zambia. The study will assess gestational age by early ultrasound and collect data and specimens throughout pregnancy and at delivery with standardized systems to document complications of pregnancy and assessment of birth outcomes. Data and specimens will be used to evaluate the causes of preterm birth and investigate novel strategies for prevention.

Preventing Preterm Birth
1 Jul 2013

David Eschenbach and his team from the University of Washington in the U.S. will determine the effect of disturbances in the vaginal microbiome on preterm birth. Their research will investigate how specific vaginal bacterial infections and changes in the female reproductive tract are associated with preterm birth. The long-term goal is to identify new ways for early identification and treatment of women at risk of preterm birth and develop a point-of-care diagnostic test appropriate for low-resource settings, which would function much like a home pregnancy test, indicating an elevated risk of premature birth.

Systems Biology of Preterm Birth: A Pilot Study

Preventing Preterm Birth
1 Feb 2013

Stephen Lye at Mount Sinai Hospital in Canada and his team will initiate a pilot study that will use a systems biology analysis of genomic, proteomic and plasma markers to identify novel pathways and biomarkers to preterm birth, as well as define the risk of preterm birth in pregnant women. Previous efforts to identify pathways or biomarkers associated with preterm birth have focused on single methodological approaches. With new capabilities in computational analyses, it is now possible to integrate information from multiple analytic techniques – collectively known as systems biology – to derive informative pathways and potential diagnostic biomarkers.
