Research Projects

Reducing Asphyxia-Related Perinatal Mortality in Resource-Limited Settings

Brett D. Nelson, MD, MPH, DTM&H, and collaborators are committed to addressing the leading causes of mortality during the most dangerous time in life: the few moments around birth. Each year, nearly 3 million newborn deaths and 3 million stillbirths occur worldwide. The vast majority of these perinatal deaths occurs in low- and middle-income countries and are most commonly a result of asphyxia (intrapartum-related complications), infection, prematurity and birth complications. Nearly all of these deaths are preventable. However, there has been limited success in implementing proven interventions in resource-limited settings. A critical next step in reducing millions of annual perinatal deaths is assessing barriers to the successful introduction and sustainability of proven interventions. With this aim in mind, Dr. Nelson is currently leading the critical evaluation of country-level newborn training programs in East and West Africa.

Analysis of the Effects of In-Utero Antiretroviral Exposure on Longitudinal Growth of HIV-Exposed Uninfected Infants in Botswana

Kate Powis, MD, MPH, MBA, is an investigator in two NIH-funded Botswana-based randomized controlled trials which investigated mother-to-child transmission (MTCT) of HIV. She is using data collected in the Mashi and Mma Bana studies to evaluate any difference in growth patterns over the first 24 months of life for HIV-exposed uninfected infants born to HIV-infected women who either took three antiretroviral drugs or zidovudine during pregnancy for prevention of MTCT.

Research on the Issues Surrounding HIV-Infected Pregnant Women and Their Infants:

Kate Powis, MD, MPH, MBA, is a co-investigator in two NIH-funded Botswana-based randomized controlled trials (RCT):

  • The Mpepu study initiated enrollment in May 2011 and with over 2,500 HIV-infected women and their HIV-uninfected infants enrolled thus far and total planned accrual of approximately 3,700 mother-infant pairs. Infants will be randomized to daily cotrimoxazole (CTX) or placebo from as early as 14 days of life through 15 months of life. For mothers opting to breastfeed, infants will be randomized to 6 or 12 months of breastfeeding. Infant HIV-free survival will be analyzed at 18 months of life based upon randomization to CTX or placebo. Additionally, 2010 revised World Health Organization guidelines recommending 12 months of breastfeeding in resource-limited settings, the Mpepu study will be the first randomized controlled trial to provide evidence-based outcomes of HIV-transmission rates and HIV-free survival outcomes comparing 6 months to 12 months of breastfeeding.
  • Early Infant Treatment: HIV-exposed infants born in selected hospitals in Botswana will undergo HIV testing on day of birth.  Any infants found to be HIV-infected will be initiated on treatment within 24 hours of a positive result and followed through at least two years of life.  This study will establish PK levels of antiretroviral drugs in the first weeks of life in order to devise safe dosing guidelines and will explore whether or not early initiation of antiretroviral treatment in HIV-infected infants prevents the establishment of viral reservoirs.

Determinants of Malnutrition in Botswana among Children under the Age of 5

  • This cross sectional study enrolled infants and children under the age of 5 attending well-child visits at government health facilities in Botswana, along with their caregivers in 2013 and 2014.  Over 1,600 child-caregiver pairs were enrolled in the study.  Anthropometric measures were obtained from the infant/child, their health records were abstracted and socio-demographic information was solicited from their caregiver.  This study represents a collaboration between Botswana Harvard AIDS Institute Partnership, Botswana Ministry of Health and Massachusetts General Hospital. Results of the study are being used by Botswana Ministry of Health to alter national healthcare and nutrition policies.  The dataset from the study is available to interested residents for smaller research projects/publications.  Interested residents should contact Kate Powis at

Evaluating the prevalence and causes of anemia amongst females in India using needleless technology

Nupur Gupta MD, MPH

Anemia is a major contributor to maternal and child death. It is a preventable cause of mortality and morbidity, yet it continues to affect a third of the world’s population and causes 68 million disability adjusted life years (DALYS). The prevalence of anemia in India is staggering, with estimates suggesting that 88% of pregnant women, 55% of non-pregnant women, and 70% of children under-5 are affected. Iron-deficiency anemia increases risk of preterm labor and low birth rate, child and maternal mortality; negatively impacts the cognitive development and physical growth of children, and weakens both the mother and child's immune response to infection. Amongst adolescent girls, physical growth and menses can aggravate anemia and place young girls at risk for complications and mortality during their pregnancy. Anemia during pregnancy can contribute to maternal death by exacerbating hemorrhage, septicemia, eclampsia, and cardiac arrest. In India although anemia has long been recognized as a problem four decades of efforts have failed to make a significant impact on the burden of this disease. Also the adolescent female population has been left out of both national data collection efforts and interventions. Adolescence is an ideal time for detection and correction of anemia prior to pregnancy. In many states in India the average age at marriage for girls is 15 years old, and by 19 years of age, 36% of women have begun childbearing, making the adolescent years an essential time for intervention. Accurate measurement of anemia is essential to providing adequate care and treatment.   Clinical examination and current measures employed are inaccurate and require a pinprick, which may cause pain, discomfort and increased risk of infection for the participants. There is a critical need for accurate and acceptable hemoglobin monitoring tools for resource-limited settings, accurate prevalence data in adolescent females and an understanding of the factors contributing to poor compliance of iron folic acid interventions.  The Pronto-7 device (Masimo) is a FDA approved pulse oximeter that provides accurate hemoglobin estimation. 

The objectives of the study are the following:

  • Determine the prevalence of anemia amongst adolescent girls and pregnant women, using the FDA approved Pronto-7 device,
  • Elucidate factors contributing to the high burden of anemia, as well as reasons that current interventions are failing to achieve a significant impact.

The results of the study will help us lay the foundation for a culturally acceptable educational or incentive based program aimed toward eradication of anemia in rural female population in India.  Eliminating iron-deficiency anemia in this population will help reduce maternal and child mortality.  

Education Opportunities

Pediatric “Longitudinal Elective in Global Health” (LEiGH)

The Division has established a rigorous pediatric global health curriculum that provides residents an essential understanding of how to deliver effective clinical care in resource-poor settings and unique clinical needs of immigrant families for whom residents provide care in their continuity outpatient clinics. Energetic faculty members collaborate to provide expert resident training in global health through engaging presentations interspersed in the resident longitudinal curriculum and mentoring residents in global health clinical elective experiences. Topics include global burden of disease, child nutrition, newborn and maternal-child health, and infectious diseases, global health professionalism, and practical skills that you “must know before you go” on an international elective.

Residents have the opportunity to work globally during Global Health Clinical Electives in safe, mentored, and educational environments. Our residents have worked at well-developed sites in Botswana, Uganda and Mexico. Some residents have opted to coordinate their own elective sites, with vetting and approval from the Division of Pediatric Global Health. These have included Tanzania, Guatemala, Haiti and Geneva. Our residents benefit from the expertise of a diverse faculty working in a multitude of international settings who are eager to serve as mentors to the next generation of leaders in pediatric global health.

“Clinical Topics in Global Health,” a Global Health and Tropical Medicine Course at Harvard Medical School

This global health course, co-directed by Brett D. Nelson, MD, MPH, DTM&H, and Peter Moschovis, MD, is a novel clinical skills-based curriculum established for Harvard medical students and residents with the primary objective of providing participants with essential clinical knowledge and skills to work effectively in resource-limited settings. The course consists of 10 evening sessions taught by a multidisciplinary faculty, with curriculum focused on the practical management of the leading causes of mortality and morbidity in low- and middle-income countries.

Currently there are three overseas sites where MassGeneral Hospital for Children residents can participate in mentored clinical electives.


Botswana is a land-locked middle-income country located in southern Africa, and bounded by South Africa to the south, Zambia to the north, Zimbabwe to the east and Namibia to the west. The population is slightly greater than 2 million people. Formerly a British Protectorate, in 1966 Botswana gained its independence and has had a democratic and stable political system. In 1967, large quantities of diamonds were discovered. The gross domestic product of the country relies on the diamond and tourism sectors predominantly.

Botswana has the second highest prevalence of HIV among adults aged 15 to 49. The HIV epidemic in Botswana led to support from the United States government in the form of the President’s Emergency Plan for AIDS Relief (PEPFAR) initiated by President Bush. PEPFAR funding continues to support activities to control Botswana’s HIV epidemic. In late 1990s, Professor Max Essex of the Harvard T.H. Chan School of Public Health met with President Fetus Mogae and formed the Botswana-Harvard AID Institute Partnership (BHP), a collaboration between the Botswana government and Harvard School of Public Health to build laboratory capacity within the country to manage the HIV epidemic. This organization is one of the country’s national lab sites for HIV viral load testing. Activities have expanded to research, public health policy, and clinical education. In 2009, a partnership between BHP and Scottish Livingstone Hospital (SLH) was created to improve the overall quality of hospital care and provide a training site for Boston area residents. Scottish Livingstone is a district hospital with 350 beds and substantial outpatient services.

This clinical site accepts pediatric and med-peds residents to work on inpatient pediatrics and adult medicine wards, the outpatient pediatric HIV clinic, and outpatient adult medicine, accident and emergency centers. There are opportunities to engage in a quality improvement project selected from a list of initiatives deemed to be important to the hospital’s management team. The contact person for this site is Dr. Kate Powis.

Mbarara, Uganda

Sub-Saharan Africa faces a most daunting challenge: it bears 25 percent of the global burden of disease but has only 3 percent of the world’s health workers. With a population of 37 million, Uganda is one of Africa's largest and fastest-growing countries. Despite rapid economic growth realized in the past decade, many Ugandans still live in poverty and confront several social and economic inequities: 65 percent of its population lives on less than US$2 per day. Training and retention of professional health staff is a serious problem, and Uganda is no exception. Under the auspices of the Mass General Center for Global Health, Mass General has developed a multidisciplinary collaborative relationship with Mbarara University of Science and Technology (MUST) and Mbarara Regional Referral Hospital (MRRH), as well as with the health center at Bugoye, a level III rural health center serving 35,000 people located approximately three hours by car northwest of Mbarara. Residents from the Mass General departments of Pediatrics, Medicine, Surgery, OB-GYN, Anesthesia, and others regularly visit MUST to collaborate on research and education. Additionally, the Bugoye Health Center is a primary training site for residents in the Mass General Global Primary Care Program.

Faculty in the Department of Pediatrics at MRRH, in the Mass General Center for Global Health, and in the Division of Pediatric Global Health at MassGeneral Hospital for Children are engaged in a diverse focus of research, including malaria, TB, pneumonia, HIV, and neonatal resuscitation. A collaborative initiative is presently underway to develop a regional oncology center at MRRH, with support from the Mass General Cancer Center and the Uganda National Cancer Institute.

At the Mbarara Regional Referral Hospital (MRRH), Mass General pediatric residents have the opportunity to work alongside Ugandan pediatricians and trainees from the Mbarara University of Science and Technology (MUST) to provide inpatient and outpatient care and to develop educational initiatives in a resource-constrained setting. Mass General pediatric faculty are currently active in research projects and medical education at MUST, and provide close mentorship and support for pediatric resident who chose to train at this site. The contact person for this site is Dr. Kate Powis.
