The increasing resistance to antimicrobial drugs is a growing public health concern, particularly in low- and middle-income countries that require high out-of-pocket payments for prescription drugs.

“Understanding the drivers of antibiotic resistance in low- to middle-income countries is important for wealthier nations because antibiotic-resistant pathogens, similar to other communicable diseases, do not respect national boundaries,” said Marcella Alsan, MD, PhD, MPH, the lead author of the study, which was published July 9 in The Lancet Infectious Disease.

Alsan is an assistant professor of medicine at Stanford, an investigator at the Veterans Affairs Palo Alto Health Care System and a core faculty member at the Center for Health Policy/Center for Primary Care and Outcomes Research.

“Out-of-pocket health expenditures are a major source of health-care financing in the developing world,” said Jay Bhattacharya, MD, PhD, senior author of the study and a professor of medicine, a senior fellow at the Freeman Spogli Institute for International Studies and another core faculty member at CHP/PCOR.

“I am the first child of my parents. I have a small brother at home. If the first child were a son, my parents might be happy ... but I am a daughter. I complete all the household tasks, go to school, again do the household activities in the evening … my parents do not give value or recognition to me.”

 

Stanford Assistant Professor of Medicine Marcella Alsan often refers to this comment by a 15-year-old girl from Nepal when she talks about how the division of labor among men and women starts at a young age in the developing world.

“Anecdotally, girls must sacrifice their education to help out with domestic tasks, including taking care of children, a job that becomes more onerous if their younger siblings are ill,” said, Alsan, a core faculty member at the Center for Health Policy/Center for Primary Care and Outcomes Research (CHP/PCOR) within the Freeman Spogli Institute of International Studies, and the Department of Medicine.

More than 100 million girls worldwide fail to complete secondary school, despite research that shows a mother’s literacy is the most robust predictor of child survival. So Alsan is analyzing whether medical interventions in children under 5 tend to lead their older sisters back to school.

She is one of two winners of this year’s Rosenkranz Prize for Health Care Research in Developing Countries, awarded by CHP/PCOR to promising young Stanford researchers.

Her Stanford Department of Medicine colleague, Jason Andrews, is the other recipient of the $100,000 prize given to young Stanford researchers to investigate ways to improve access to health care in developing countries.

Andrews is looking at cheap, effective diagnostic tools for infectious diseases, while Alsan is researching how older girls in poorer countries are impacted by the health of their younger siblings.

“My proposed work lays the foundation for a more comprehensive understanding of how illness in households and early child health interventions impact a critical determinant of human development: an older girl’s education,” she said.

Alsan, the only infectious-disease trained economist in the United States, said Stanford is the ideal place to carry out her interdisciplinary global health research.

“I am humbled and honored to receive this prize, since Dr. Rosenkranz has done so much for women’s health worldwide,” she said.

Alsan – an MD with a specialty in infectious disease who has a PhD in economics from Harvard – said she intends to estimate the impact that illnesses in under-5 children have on older girls’ schooling using econometric tools.

She will compile data from more than 100 Demographic and Health Surveys (DHS) covering nearly 4 million children living in low- and middle-income countries.

The surveys ask about episodes of diarrhea, pneumonia and fever in children under 5 and record data on literacy and school enrollment for every child in the household.

Alsan also intends to collaborate with partners in sub-Saharan Africa to study the gendered effect of household illness on time use, using culturally appropriate questionnaires.

Douglas K. Owens, a Stanford professor of medicine and director of CHP/PCOR, called Alsan’s work “groundbreaking.”

“Although training is critical, more importantly, her work to date shows a degree of innovation, creativity and rigor that led us to conclude she was likely to become one of the top investigators in her field worldwide,” he said.

Low-Cost Diagnostic Tools

Andrews, also an assistant professor of medicine, has been working on ways to bring low-cost diagnostic tools to impoverished communities that bear the brunt of disability and death from infectious disease.

“I began working in rural Nepal as an undergraduate student and as a medical student founded a nonprofit organization that provides free medical services in one of the most remote and impoverished parts of the country,” Andrews said. “As I became a primary physician, and then an infectious diseases specialist, one of the consistent and critical challenges I encountered in this setting was routine diagnosis of infectious disease.”

He said those routine diagnostics were typically hindered by lack of electricity, limited laboratory infrastructure and lack of trained lab personnel.

“In my experiences working throughout rural Nepal – and in India, South Africa, Brazil, Peru and Ethiopia – I found these challenges to be common across rural resource-limited settings,” said Andrews, who founded a nonprofit Nyaya Health – recently renamed Possible Health – which provides modern, low-cost healthcare to rural Nepal.

Andrews has been collaborating with engineers to develop an electricity-free, culture-based incubation and identification system for typhoid; low-cost portable microscopes to detect parasitic worm infections; and most recently an easy-to-use molecular diagnostic tool that does not require electricity.

“The motivation for these projects was not to develop fundamentally new diagnostic approaches, but rather to find simple, low-cost means to make established laboratory techniques affordable and accessible,” he said.

Image
The Rosenkranz Prize will allow him to continue to develop a simple, rapid, molecular diagnostic for cholera that is 10 times more sensitive than the tests that are currently available. The diagnostic tool uses paper for DNA extraction, in contrast to traditional approaches that rely on expensive instruments requiring electricity and maintenance.

“We then perform isothermal amplification heated by a reusable, solar-heated, phase-change material,” Andrews said, adding that the entire process is completed in less than 20 minutes and can be performed by anyone with minimal training.

Andrews will enroll 250 patients with suspected cases of cholera in Nepal, using the new diagnostic tools and adapting as many local supplies as possible.

Andrews also intends to establish and curate a website to gather open-source ideas and evidence on diagnostic techniques for use in the developing world.

“Stanford is one of the world’s greatest hubs for innovation and information sharing as pertains to science and technology and is an ideal home for this venture,” he said.

In the current scientific climate, most National Institutes of Health grants go to established researchers. The Rosenkranz Prize aims to stimulate the work of Stanford’s bright young stars – researchers who have the desire to improve health care in the developing world, but lack the resources.

The award’s namesake, George Rosenkranz, first synthesized cortisone in 1951, and later progestin, the active ingredient in oral birth control pills. He went on to establish the Mexican National Institute for Genomic Medicine, and his family created the Rosenkranz Prize in 2009.

The award embodies Dr. Rosenkranz’s belief that young scientists hold the curiosity and drive necessary to find alternative solutions to longstanding health-care dilemmas.

“As in past years, the competition was extremely tough,” said Grant Miller, a senior fellow at the Freeman Spogli Institute and associate professor of medicine who chaired the prize committee this year.

“It’s exciting to see all of the truly innovative global health research being done by junior scholars at Stanford,” he said. “Both Jason and Marcella really exemplify this – and the legacy of George Rosenkranz.”

Maria Polyakova, an assistant professor of health research and policy at the Stanford School of Medicine, is this year’s recipient of the Ernst-Meyer Prize, which recognizes original research about risk and health insurance economics.

Polyakova, who wrote her thesis, “Regulation of Public Health Insurance,” while working on her Ph.D. in economics at MIT, was given the award by The Geneva Association, an international insurance economics think tank based in Switzerland.

Image
Christophe Courbage, research director of the health and aging and insurance economics programs at the association, made the announcement Tuesday. He called Polyakova’s work “an important and insightful thesis on a set of first order – but understudied – issues in insurance: namely the regulation of privately provided social insurance.”

Courbage said the topic not only had considerable academic interest, but also was “an important public policy issue in both the United States and Europe.

“This work makes extremely useful insights about an important area of public policy that has yet to get the attention it needs: the interaction of regulation with important demand and supply-side features of private insurance markets.”

Polyakova said she was honored to receive the award and thanked her thesis committee for their “unbounded support” of her work.

“I am especially grateful to Amy Finkelstein for inspiring my interest in social insurance in general, and health insurance, in particular,” she said. “I hope to continue my work in this area."

A summary of Polyakova’s thesis will be published in the July 2015 issue of The Geneva Association’s Insurance Economics newsletter.

Stanford School of Medicine Dean Lloyd Minor told a distinguished group of visiting physicians, engineers, economists and businessmen from India that it was the perfect time to be collaborating with the world’s largest democracy.

As India’s economy heats up once again and biomedical research scales across the South Asian nation, Stanford intends to remain a key partner in this growth.

“India is on a journey to overcome its challenges,” Minor said. “Despite the substantial gaps in healthcare infrastructure and a shortfall of skilled healthcare workers, there’s enormous opportunity and enormously good work going on today – most of it being done by the people in this room.”

Minor was addressing a healthcare and policy panel during the two-day held on the Stanford campus on May 28-29. Reigniting India’s Growth: Perspectives from Business, Engineering, Medicine and Economics was sponsored by the Stanford Center for International Development, the Graduate School of Business, the schools of Engineering and Medicine, as well as the Office of the Vice Provost and Dean of Research.

“I’m really eager to explore ways that we can deepen the collaboration and interactions between Stanford and India,” Minor said. “As I’m sure everyone here is aware, India is the world’s most populous democracy, one of the fastest growing major economies and a rising power with growing international influence – led by a prime minister who has great ambitions for the country.”

Prime Minister Narendra Modi has said his core mission is the revival of the Indian economy – once a powerhouse destined to rival that of China. Since taking office last year, when economic growth stood at 5 percent, the IMF forecasts India’s economy will grow to 7.5 percent by the end of this year.

Stanford has many partnerships with India, such as the Stanford-India Biodesign project to train the next generation of medical technology innovators in India. In 2007, Stanford joined with the nonprofit GVK Emergency Management Research Institute, based in Hyderabad, India, to train the country’s first corps of paramedics.

Minor noted that the Stanford-India Biodesign program has led to the founding of 37 biotech companies. “And the technologies that they have invented have been used in the care of over 300,000 patients – and that’s only the beginning,” he said.

Stanford physicians developed an educational curriculum and have trained thousands of paramedics and emergency instructors in India. EMRI says that since the training program began, more than 150,000 healthcare professions have been trained at its training center.

“These paramedics instructors have played a crucial role in the development of emergency medicine in India,” he said. “It’s been a true collaboration with a curriculum developed here in the U.S. and then standardized and implemented in a way that’s meaningful for people in India.”

Grant Miller, an associate professor at the School of Medicine and a senior fellow at the Freeman Spogli Institute for International Studies, is the director of the Stanford Center for International Development, which organized and co-hosted the India conference.

Image
“This year’s India Conference was new for SCID in that it was a cross-campus collaboration, partnering us with the business school and schools of medicine and engineering,” said Miller, also a core faculty member at CHP/PCOR.

“We feel that there is great potential for more campus-wide activity focused on India, enabling Stanford to develop new partnerships in India as well as across parts of our own university.”

Miller also launched the Stanford India Health Policy Initiative with another CHP/PCOR researcher, Nomita Divi. The initiative, connected with FSI’s International Policy Implementation Lab, joins Stanford with Indian health policymakers and professionals to design collaborative projects in India.

Last year the SIHPI fellows spent the summer investigating the factors that motivate formal and informal healthcare providers. This summer, three Stanford undergrads and a medical student will do fieldwork on the outskirts of Mumbai for seven weeks to document the impact of existing pharmaceutical networks on formal and informal provider practices.

“Health improvement is of course a critical objective of broad-based social and economic development, and we are very excited to see Stanford’s potential to make interdisciplinary contributions to health improvement in India,” Miller said on the sidelines of the India conference.

The conference featured four panel sessions in which perspectives from economics, business, engineering and medical sectors were debated. Discussions focused on how best to combine these to ensure sustained high growth in the Indian economy.

Each session featured a distinguished panel of speakers, and was followed by a lengthy floor discussion. Among the speakers were Nandan Nilekani, the co-founder of Infosys, one of India’s most successful IT services companies; Stanford President John Hennessy; Montek Ahluwalia, former deputy chairman of India’s Planning Commission, and Mr. K. Ram Shriram, managing partner at the venture capital firm, Sherpalo Ventures.

Ashok Alexander, former founding country director of the Bill and Melinda Gates Foundation in India, said too many India observers tout the incredible growth of its economy and highly educated and skilled technology innovators. Yet they ignore the majority of the country’s 1.2 billion people still lack adequate public healthcare and that 70 percent of medical spending comes out of pocket.

Image

 

“We cannot ignite India nor can we sustain India unless we think about the ways to fix public health problems,” Alexander said. “The solution to most public health problems in India are absurdly simple; it’s all about scaling up of well-known solutions.”

Only 1.3 percent of India’s GDP was devoted to public health in 2014, according to the World Bank. That is one of the world’s lowest rates. The risk of dying during childbirth is one in 43, whereas the rate in developed countries is one in 4,000.

“While India is making such great strides in its energy and business sectors, how come there is no great debate on public health?” he asked.

Amit Sengupta, a senior biomedical consultant at Tata Memorial Center and adjunct professor at ITT/AIIMS in New Delhi, told the medical panel that modern medicine is still not the first preference in rural Indian and the urban slums.

“Health is not only a biomedical issue, but also sociocultural issue,” he said. “Fifty percent of the world’s tribal population lives in India; it’s a rich heritage but they eschew Western medicine.”

Sengupta said rural India is plagued by physical and psychological stress, alcoholism and domestic violence. Meanwhile, he said, the government continues to cut the healthcare budget – a cycle that always leads back to poverty.

And, he said, remember Gandhi’s memorable saying: “Poverty is the worst form of violence.”

Abstract:  Foreign aid for health in low- and middle-income countries has increased five-fold over the past 25 years.  Between 2005 and 2010, health aid made up more than 30% of all health spending in low-income countries.  Global health is also an increasingly important component of U.S. foreign aid, rising steadily from under 4% of all U.S. non-military aid in 1990 to 22.7% in 2011.  There is growing evidence for the role of health aid in improving health among recipient countries, but is that it?  In this talk I will address the arguments for and against health as a focus of aid efforts and present initial evidence on the role of health aid on human capital and economic development.

My academic focus is on global health, health policy, infectious diseases, environmental changes, and population health. Our research primarily addresses how health policies and environmental changes affect health outcomes worldwide, with a special emphasis on population living in impoverished conditions.

Our recent publications in journals like Nature, Lancet, and JAMA Pediatrics include studies on the impact of tropical cyclones on population health and the dynamics of SARS-CoV-2 infectivity in children. These works are part of my broader effort to understand the health consequences of environmental and policy changes.

Collaborating with trainees and leading academics in global health, our group's research interests also involve analyzing the relationship between health aid policies and their effects on child health and family planning in sub-Saharan Africa. My research typically aims to inform policy decisions and deepen the understanding of complex health dynamics.

Current projects focus on the health and social effects of pollution and natural hazards, as well as the extended implications of war on health, particularly among children and women.

Specific projects we have ongoing include:

  • What do global warming and demographic shifts imply for the population exposure to extreme heat and extreme cold events?

  • What are the implications of tropical cyclones (hurricanes) on delivery of basic health services such as vaccinations in low-income contexts?

  • What effect do malaria control programs have on child mortality?

  • What is the evidence that foreign aid for health is good diplomacy?

  • How can we compare health inequalities across countries? Is health in the U.S. uniquely unequal?

The study provides evidence that a country’s ability to reduce the gap in child-mortality rates is related to good governance.

The child-mortality gap has narrowed between the poorest and wealthiest households in a majority of more than 50 developing countries, a new study from the Stanford University School of Medicine has found.

This convergence was mostly driven by the fact that child-mortality rates declined the fastest among the poorest families. In the countries where the gap increased, the study identified a common thread: poor governance.

The findings provide important information for making decisions about prioritizing global health investments to effectively promote equity, said Eran Bendavid, MD, assistant professor of medicine, core faculty member at CHP/PCOR, and the study’s author.

The study, published online Nov. 10 in Pediatrics, analyzed data from nearly 1 million families living in 54 low- and middle-income countries to determine the relationship between mortality in children under the age of 5 and wealth inequality.

“In many countries, national wealth has increased hand-in-hand with increasing health inequality. That’s been a signature of our time,” Bendavid said. “It’s a pressing concern for many societies, especially in wealthy countries, but it’s also been an issue in low- and middle-income countries.”

Assessing child mortality within developing countries

Many studies have assessed the national child mortality trends in developing countries, but they say little about the mortality gap between the poorest and wealthiest within those countries. National trends could be associated with either narrowing or widening gaps between the poorest and wealthiest populations, Bendavid noted. For example, if child mortality decreases faster among the wealthy compared with the poor, the overall child-mortality rate in that country could decrease even as the mortality gap widens. Alternatively, if child mortality decreases faster among the poor, the health gap could narrow.

To fill this gap in knowledge, the study sought to understand whether developing countries are experiencing a widening or narrowing mortality-rate gap among children under 5 of the poorest and wealthiest families.

To compare wealth status and under-5 child mortality within a country, Bendavid used data from the demographic and health surveys for 1.2 million women living in 929,224 households in 54 developing countries. The women provided information about their children’s survival status. 

 “The people who conduct these surveys, they’re intrepid surveyors,” said Bendavid, who is also a core faculty member of Stanford Health Policy, which is part of the Freeman Spogli Institute for International Studies. “They reach remote villages up the Congo basin and in the Sahel in Niger, and track the heads of households and women for these in-depth interviews.”

The surveys include information about each woman’s birth histories, including detailed birth registries documenting millions of children. With this information, Bendavid could estimate the probability of a child dying before reaching age 5 per 1,000 live births.

Tallying household possessions

Determining each household’s wealth status was not as straightforward as reviewing annual income and tax returns, which don’t exist in the countries involved in the study. “These surveys tally the possessions in the household. What is the floor made of? What is the roof made of?” Bendavid said. “You can get a wide distribution of household possessions that reflects to a large degree the household wealth.”

Next, Bendavid developed a three-tier wealth index using the household assets. The three wealth categories were relative — poorest, middle and wealthiest.

To analyze trends in wealth status and under-5 mortality, Bendavid looked at all developing countries that had completed the surveys in two specific time frames: 2002-07 and 2008-12. The study found that the under-5 mortality rates among the poorest groups had decreased the most rapidly. The average decline was 4.36 deaths each year per 1,000 live births among the poorest, 3.36 among the middle and 2.06 among the wealthiest. Because the poorest group’s mortality rate is decreasing more quickly that the other groups, the gap in child-mortality rates is closing.

This is good news, Bendavid said. However, not all countries followed this same trend. In a quarter of the surveys examined by the study, inequality in under-5 mortality increased over time.

Bendavid found that four factors were present in countries with a narrowing child-mortality gap: government effectiveness, rule of law, control of corruption and regulatory quality. He found that the difference in mortality rates was significantly associated with the governance score: Better governance scores were related to greater convergence in mortality rates among the three wealth groups.

Benefits from controlling communicable diseases

Bendavid said the evidence in this study is consistent with gains in controlling communicable diseases, such as malaria, measles, diarrhea and respiratory illnesses, that preferentially affect the poorest. Over the past decade, international health aid organizations have financed interventions for these diseases at a high rate.

It makes a persuasive case that these improvements have often begun to benefit the poor even more than the better-off.

“Dr. Bendavid’s study is an important contribution to knowledge about child health improvements in the developing world,” said Davidson Gwatkin, a senior fellow at the Results for Development Institute and a senior associate at Johns Hopkins Bloomberg School of Public Health. “It makes a persuasive case that these improvements have often begun to benefit the poor even more than the better-off.” Gwatkin was not involved in the study.

The study also raises questions about the role of foreign aid institutions in low- and middle-income countries. While the aid efforts are making a difference in child-mortality rates in countries with effective governments, the study seems to show that this is not the case in nations with poor governance, Bendavid said.

“We have the technologies, we have the means, we have the know-how to reduce child mortality dramatically,” said Bendavid. “Even for such low-hanging fruit, however, implementation is not always easy. You have to have government that enables basic safety, and the ability to reach poor and rural communities that benefit from these kinds of programs.”

This work was supported by the National Institute of Allergy and Infectious Diseases (grant KOIAI084582), the Doris Duke Charitable Foundation and the Dr. George Rosenkranz Prize for Health Care Research in Developing Countries.

In response to the current outbreak, the international community has endorsed the clinical use of unregistered treatments for Ebola. Even with this accelerated pathway to in-human testing and use, radically novel approaches to drug development will be needed to improve the likelihood that a treatment is realised. Bypassing steps in development does not alter the probability of success, and historical patterns in drug development suggest that there is a slim probability of success with the current portfolio of potential Ebola treatments (all of which are were in preclinical development prior to the outbreak)....

Traditional drug repurposing, although successful in treating some diseases, still requires considerable time to identify candidate compounds and even more time to test them in clinical trials. Ebola requires and deserves a much more aggressive approach, while still balancing safety and efficacy concerns.

One way to considerably speed up the drug development process is to use high-end, bioinformatics-oriented computing approaches. When applied to drug repurposing, this approach can allow for a much faster identification of candidate compounds. When applied to clinical trials, this approach may quickly provide valuable animal and human information without the need for actual subjects.

With bioinformatics, drug repurposing can be used quickly without resorting to desperate measures that compromise safety. These bioinformatics approaches are already under development for diseases that are prevalent in wealthy countries, like cancer; Ebola provides an opportunity for this potentially game-changing approach to be applied to a disease primarily affecting those in resource-limited countries.
