Machine-Learning Ultrasound Tools to Monitor Women's Nutrition in Ethiopia
Bryan Ranger of Boston College in the U.S. will develop a cost-effective, portable, and automated ultrasound tool to monitor nutritional health of young pregnant women in Ethiopia. The tool will incorporate AI models that guide users in collecting high quality data, so the tool can be used by frontline and community healthcare workers without extensive ultrasound training, and the models will use this data to predict metrics of nutritional status. In a pilot study conducted at the Jimma Medical center, they will create a database of ultrasound scans, anthropometry, body composition measured by gold standard techniques, and the associated clinical data from a group of young pregnant women. Ultrasound measurements will incorporate data on user position to identify the most informative positions via machine learning. They will survey clinical users to guide the ultimate design of the ultrasound system.
Remodeling Maternal Health Care: Evaluating the Impact of Midwife-Led Birthing Centers on Maternal and Neonatal Health Outcomes in Ethiopia
Solomon Hailemeskel of Debre Berhan University in Ethiopia will pilot test midwife-led birthing centers for pregnant women and newborns at low risk of complications to increase access to safe, high-quality childbirth experiences for Ethiopian women. They will implement a multicenter randomized controlled trial, recruiting a cohort of pregnant women from antenatal care clinics across diverse healthcare facilities to ensure a representative sample. After training midwives to provide continuity of care before, during, and after pregnancy, they will establish midwife-led birthing centers in dedicated spaces, either within or separate from a higher-level health facility. A subset of trial participants will be randomly assigned to the birthing centers. They will compare outcomes for the two groups, including data on maternal and neonatal health outcomes, as well as qualitative data from interviews of mothers, midwives, and healthcare providers.
Revolutionizing Decentralized Diagnosis of Bacterial Sexually Transmitted Infections for Women Worldwide
Rapidemic in the Netherlands will collaborate with Mohammed Majam of Ezintsha in South Africa to develop a prototype for a molecular test for rapid multiplex diagnosis of chlamydia and gonorrhea, while determining the requirements for its deployment in South African primary care settings to serve hard-to-reach populations. The test system will be designed to diagnose symptomatic and asymptomatic patients accurately and inexpensively using a rapid and disposable test. To guide prototyping, they will research user preferences and assess the usability of the developed device. They will also conduct research to ensure that the development meets regulatory requirements for the South African market and addresses the needs of pharmacies and primary healthcare settings in South Africa.
Meeting Them Where They Are At: Using Large Language Models to Lower Barriers to Measuring the Impact of Gender-Based Violence on Mental Health and HIV Outcomes in Girls and Women in Kenya
Mike Baiocchi of Stanford University in the U.S. will use LLMs to analyze conversational interviews with adolescent girls and young women in Kenya to identify causal mechanisms impairing their health within the potential interplay between living with HIV, mental health conditions, and gender-based violence. Working with the Kenyan Medical Research Institute, they will re-identify and enroll a previously studied cohort living with HIV. The new longitudinal dimension of the study will contribute to untangling causes and effects in parallel to the new LLM-based analysis. They will use LLMs to create statistical measures of participants' descriptions of their experiences to help identify the underlying causes, for instance detecting differences between the responses of those experiencing violence or depression compared to those who have not. Such improved understanding will help to design and target appropriate health interventions.
Acceptability and Marketing of Innovative, Quick-Drying, Reusable, Menstrual SunPad in Kenya
Elizabeth Nyothach of Kenya Medical Research Institute in Kenya will explore introduction of SunPad, a prototype reusable menstrual pad, determining its acceptability, marketability, and regulatory requirements in Kenya. The SunPad product is made of fabric with a built-in cleaning and disinfecting process that is activated by sunlight. They will conduct focus group discussions with women in Kenya to understand their needs in terms of washing, drying, and reusing the pad, and to gauge their willingness to pay for the product. They will also research the potential for local manufacturing of the pad and determine the regulatory requirements and associated documentation.
Integrating Traditional Birth Attendants to Strengthen Regulation and Improve Quality Maternal Care
Geraldine Mbagwu of Corona Management Systems in Nigeria will implement a pilot project in Bayelsa state in Nigeria that provides training to traditional birth attendants and links them with primary healthcare centers to improve maternal health outcomes. They will engage birth attendants and provide training on topics including using a mobile application to get the latest evidence and health guidelines, as well as training for identifying women with high-risk pregnancies and referring them to the appropriate level of care. They will also ensure access by the birth attendants to key maternal health products and services, including immunization and postpartum family planning. Better integration of traditional birth attendants into the healthcare system will embrace women's agency while improving health outcomes.
Pharmacokinetics of Primaquine in Lactating Women - Towards Equitable Radical Cure of Vivax Malaria
Brioni Moore of Curtin University in Australia will perform a trial in Papua New Guinea to validate minimal transfer through breastmilk of the antimalarials primaquine and tafenoquine to enable access by postpartum women to radical malaria cure. Verifying minimal drug transfer in the first two weeks post-birth would enable maternal treatment before hospital discharge, preventing postpartum relapses and improving maternal health outcomes and malaria control. They will recruit a cohort of mother-child pairs in which the mother has confirmed vivax malaria or a recent history of it. They will then quantify the excretion of primaquine and tafenoquine in colostrum and transitional breast milk and determine relative infant exposure, while assessing indices of neonatal physiology.
Rapid Detection of Neisseria gonorrhoeae and Relevant Antimicrobial Resistance Targets
Nicole Ertl of the University of Queensland in Australia will develop a molecular test prototype for diagnosis of gonorrhea and antimicrobial resistance of the causative agent Neisseria gonorrhoeae. To increase access to testing, they will design the nucleic acid-based test to be rapid, inexpensive, and to work at ambient temperature without the need for electricity. The prototype platform will combine a sample preparation reagent requiring only short incubation at room temperature, chemically heated isothermal amplification, and lateral flow detection. It will incorporate detection of a relevant genetic signature to distinguish sensitivity versus resistance to the relevant drugs ceftriaxone and ciprofloxacin. They will evaluate the sensitivity and specificity of this sample-to-results platform and its usability in settings with minimal laboratory and testing infrastructure.
Incorporating a Sex and Gender Lens into Medical Education in Pakistan
Zainab Samad of Aga Khan University in Pakistan will incorporate sex and gender as a cross-cutting theme embedded in medical education in Pakistan at Aga Khan University and Khyber Medical University. They will perform a curriculum review across the two universities, engaging students, faculty, university leadership, and patients to understand the current teaching gaps related to sex and gender. This will guide development of a tool kit for incorporating the sex and gender theme across all years of training, with customizable strategies based on sociocultural context. They will implement a year-long pilot test of the program at the universities, integrating the theme into core subjects, including how different diseases are recognized and treated and how treatment decisions are made. Feedback from participants in the program will be incorporated into a road map to guide other medical schools in Pakistan in revising their curriculum.
Femtech Innovation Hub
Imran Zia of the Centre for Economic Research in Pakistan (CERP) with the National Incubation Center will establish an innovation hub to support startup companies in creating practical and accessible health solutions for women living in underserved and low-income communities in Pakistan. They will establish a physical hub that is integrated with an existing research network and uses a human-centered design approach with evidence-based decision-making throughout, from product conception to launch and scale-up. They will develop and implement an open-source curriculum tailored to entrepreneurs for women's health and incubate a cohort of startups. Participating startups will be selected through gatherings held at leading medical universities and through collaboration with other incubators. The hub will lead to improved women's health outcomes, while generating insights on the health needs of women in Pakistan that can help inform national health policy.
