Sarah Murray and colleagues of Johns Hopkins Bloomberg School of Public Health and School of Nursing in the U.S. along with colleagues at the University of Bamako in Mali will develop a group approach to provide better antenatal care to pregnant adolescents in Mali and protect them from common mental disorders such as depression. Over half of adolescent girls in Mali have a child before their 18th birthday, and as a consequence are more likely to live in poverty, be uneducated, and experience violence. Although antenatal health services and support are available, they are limited. To address this, they will develop a group format for more efficient delivery of antenatal mental health care that encourages open discussions and provides social networks and support. This will be done in collaboration with adolescent mothers, their husbands, and health care providers. They will train health care workers to teach relevant coping strategies in a group format using cognitive behavioral therapy techniques, and pilot test their approach on small groups of pregnant adolescents with partners in Bamako, Mali.

Lisa Butler of the University of Connecticut in the U.S. will develop an approach to improve the mental health of pregnant and new mothers between 15 and 19 years old in Botswana that incorporates interactive group sessions mediated by trained community workers, informative text messages, and an SMS-based mental health screening tool. Between 19-25% of women in low- to middle-income countries suffer from depression during pregnancy, which can also have serious effects on the child. In Botswana, there are large numbers of young, single mothers, who lack support and are particularly vulnerable to depression. They will develop the materials and format for their approach with support from a community working group of adolescent mothers and health providers to ensure it is culturally appropriate and addresses their specific needs. They will also incorporate a theoretical model designed to address the triggers and reduce the stigma of mental health disorders. Their approach will be field tested with 80 pregnant adolescents in a traditional village in Botswana to evaluate its feasibility and acceptability.

Pushpendra Singh of IIIT Delhi in India will develop interactive training and mentoring sessions for community health workers in India (ASHAs) using mobile phones and interactive voice response systems so they can provide better public healthcare in rural communities. Current training programs are run by medical professionals and require the workers to visit a health center, which may be inconvenient. The lack of medical experts has also reduced the frequency of these programs. These limitations could be overcome with online sessions whereby one expert trains multiple health workers remotely. They have already developed the format of the sessions, which involves an expert delivering a defined curriculum to groups of health workers followed by a question and answer session, and shown that it improved the knowledge and confidence of the health workers in a pilot test. They will now scale up the testing to 500 health workers, and also evaluate the platform as a peer-to-peer learning mechanism for health workers to share their experiences and learn from each other without the need for an expert.

Xing Xie of the Georgia Institute of Technology in the U.S. will test whether super-absorbent polymers in sample tubes can improve the accuracy of diagnostics by absorbing molecules like DNA and viruses from liquid samples such as blood, and protecting them during transport to the laboratory. Normally, blood and urine samples degrade over time, particularly when they are exposed to heat or cold. This makes the subsequent diagnostic result unreliable. They propose that low-cost, super-absorbent polymers can preserve diagnostic target molecules by separating them from contaminating cells and bacteria, which can be poured away from sample tubes, and providing a pH buffer and preservatives to extend their shelf-life. They will optimize synthesis of the beads and test their ability to preserve different analytical targets including a human virus surrogate and an antibody against HIV.
