Marion Sumari-de Boer and Kennedy Ngowi from Kilimanjaro Clinical Research Institute in the United Republic of Tanzania and Rosalijn Both from Segel Research and Training Consulting in Ethiopia will use mobile phones to learn about the contraceptive needs and behaviors of young unmarried men in Ethiopia and Tanzania in order to promote the use of contraception. This group is mostly overlooked in studies aiming to improve contraceptive and family planning practices, even though their behavior is directly relevant.

Howard Ochman of the University of Texas in the U.S. will develop an approach to identify bacteria that can spread antibiotic resistance genes to other bacteria and harm human health. Most methods for monitoring antibiotic resistance are used once resistance has occurred. Here they will measure the capacity for developing resistance, which should help better evaluate how antibiotic resistance persists, spreads and circulates on a global scale.

Jane Harries of the University of Cape Town in South Africa will take a multisensory approach to increase the use of contraception, particularly over the long term, across South Africa. By exploring how different contraceptives are perceived via multiple senses, not only visual perceptions but also how they feel, and how their use impacts the daily life of the woman, and her wider network, they hope to identify new barriers that influence uptake.

Paul Crits-Christoph and Chelsea Morroni of the University of Pennsylvania in the U.S. will develop a mobile phone application that enables women to identify the method of contraception best suited to their needs to help reduce the number of unwanted pregnancies in Botswana, which is currently estimated at 44%. Although around 61% of women are reported to not want any more children, the most commonly used contraceptives are single use, such as condoms, despite the availability of longer-term measures like intrauterine devices.

Martin Matzuk, along with Nicholas Simmons of Baylor College of Medicine in the U.S. and Masahito Ikawa of Osaka University in Japan, will build a male contraceptive drug discovery platform comprising a library of two billion small compounds generated by DNA-Encoded Chemistry Technology (DEC-Tec) at relatively low cost, and a panel of male-specific fertility proteins. Contraception options for men are currently limited to condoms or vasectomy. A safe, low-cost small molecule contraceptive similar to the female "pill", could also help men to better control family planning.

Alison Norris of Ohio State University in the U.S. will perform a prospective study to assess how individuals' contraceptive needs and identified barriers explain contraceptive use over time for developing a simple tool to prevent unintended pregnancies in Malawi. In collaboration with a Malawi NGO, they will access their cohort of one thousand reproductive age women and their partners in rural Malawi. Study team members will visit each participant in their home four times over eight months to assess factors related to contraceptive need such as pregnancy desire, and perceived fecundity.

Léger Foyet of Population Services International in the U.S. along with the Organization to Advance Solutions in the Sahel (OASIS) and the High Commission of the Nigeriens Nourish Nigeriens agriculture initiative (HC3N) will improve gender equity, nutrition, and access to family planning in Niger. Niger has one of the highest levels of poverty and malnutrition. Women in Niger are usually married before the age of 16 and have on average around eight children. Men generally make the decisions on family planning, and there is limited access to contraceptives and healthcare.

John Belisle of Colorado State University in the U.S. will assess the feasibility of using small molecules created by the metabolic processes of host or pathogen cells, as well as lipids and fatty acids produced by the TB bacterium, as biomarkers of active disease.

Paul Kelly of Queen Mary and Westfield College in the United Kingdom and the University of Zambia will work with colleagues to identify and evaluate candidate biomarkers of environmental enteropathy, which causes growth failure in children in the developing world. Possible markers of enteropathy in serum and gut secretions will be correlated with two severe clinical outcomes, impaired nutrient absorption, and loss of gut barrier function leading to bacteria entering the bloodstream. The aim is to drive the development of new treatments.

Asad Ali of Aga Khan University in Pakistan and co-­investigators will test a selected group of candidate biomarkers to identify and monitor environmental enteropathy, which causes malnutrition and stunting. The biomarkers, which include markers of inflammation and enteric pathogens, will be tested in blood, urine and stools, and correlated with structural features of the small bowel using biopsies from malnourished children. They will also attempt to identify new candidate biomarkers in these biopsies using mRNA sequencing.
