More children die from the indirect impact of armed conflict in Africa than those killed in the crossfire and on the battlefields, according to a new study by Stanford researchers. 

The study is the first comprehensive analysis of the large and lingering effects of armed conflicts — civil wars, rebellions and interstate conflicts — on the health of noncombatants.

The numbers are sobering: 3.1 to 3.5 million infants born within 30 miles of armed conflict died from indirect consequences of battle zones between 1995 and 2005. That number jumps to 5 million deaths of children under 5 in those same conflict zones.

“The indirect effects on children are so much greater than the direct deaths from conflict,” said Stanford Health Policy's Eran Bendavid, senior author of the study published today in The Lancet.

The authors also found evidence of increased mortality risk from armed conflict as far as 60 miles away and for eight years after conflicts. Being born in the same year as a nearby armed conflict is riskiest for young infants, the authors found, with the lingering effects raising the risk of death for infants by over 30 percent.

On the entire continent, the authors wrote, the number of infant deaths related to conflict from 1995 to 2015 were more than three times the number of direct deaths from armed conflict. Further, they demonstrated a strong and stable increase of 7.7 percent in the risk of dying before age 1 among babies born within 30 miles of an armed conflict.

The authors recognize it is not surprising that African children are vulnerable to nearby armed conflict. But they show that this burden is substantially higher than previously indicated. 

“We wanted to understands the effects of war and conflict, and discovered that this was surprisingly poorly understood,” said Bendavid, an associate professor of medicine at Stanford Medicine.  “The most authoritative source, the Global Burden of Disease, only counts the direct deaths from conflict, and those estimates suggest that conflicts are a minuscule cause of death.”

Paul Wise, a professor of pediatrics at Stanford Medicine and a senior fellow at the Freeman Spogli Institute for International Studies, has long argued that lack of health care, vaccines, food, water and shelter kills more civilians than combatants from bombs and bullets. 

This study has now put data behind the theory when it comes to children.

“We hope to redefine what conflict means for civilian populations by showing how enduring and how far-reaching the destructive effects of conflict have on child health,” said Bendavid, an infectious disease physician whose co-authors include Marshall Burke, PhD, an assistant professor of earth systems science and fellow at the Center on Food Security and the Environment.

“Lack of access to key health services or to adequate nutrition are the standard explanations for stubbornly high infant mortality rates in parts of Africa,” said Burke. “But our data suggest that conflict can itself be a key driver of these outcomes, affecting health services and nutritional outcomes hundreds of kilometers away and for nearly a decade after the conflict event”. 

The results suggest efforts to reduce conflict could lead to large health benefits for children.

The Data

The authors matched data on 15,441 armed-conflict events with data on 1.99 million births and subsequent child survival across 35 African countries. Their primary conflict data came from the Uppsala Conflict Data Program Georeferenced Events Dataset, which includes detailed information about the time, location, type and intensity of conflict events from 1946 to 2016. 

The researchers also used all available data from the Demographic and Health Surveys conducted in 35 African countries from 1995 to 2015 as the primary data sources on child mortality in their analysis.

The data, they said, shows that the indirect toll of armed conflict among children is three-to-five times greater than the estimated number of direct casualties in conflict. The indirect toll is likely even higher when considering the effects on women and other vulnerable populations.

Zachary Wagner, a health economist at RAND Corporation and first author of the study, said he knows few are surprised that conflict is bad for child health.

“However, this work shows that the relationship between conflict and child mortality is stronger than previously thought and children in conflict zones remain at risk for many years after the conflict ends.” 

He notes that nearly 7 percent of child deaths in Africa are related to conflict and reiterated the grim fact that child deaths greatly outnumber direct combatant deaths.

“We hope our findings lead to enhanced efforts to reach children in conflict zones with humanitarian interventions,” Wagner said. “But we need more research that studies the reasons for why children in conflict zones have worse outcomes in order to effectively intervene.” 

Another author, Sam Heft-Neal, PhD, is a research fellow at the Center for Food Security and the Environment and in the Department of Earth Systems Science. He, Burke and Bendavid have been working together to identify the impacts of extreme climate events on infant mortality in Africa.

There are a billion guns in the world today. Those firearms took the lives of about 251,000 people in 195 countries in 2016, according to new research. 

That’s a lot of guns and fatalities, mostly by homicide, suicide and accidents with firearms.

About 35 percent of those gun deaths were by Americans committing suicide.

In the most comprehensive investigation of its kind, the findings, published this week in the Journal of the American Medical Association (JAMA), show 64 percent of firearm-related deaths were homicides, 27 percent were suicides and 9 percent were unintentional deaths.

And in all but one year of the 27-year study period — 1994 due to the Rwandan genocide — firearm deaths were more common along sidewalks than on the battlefields.

“This constitutes a major public health problem for humanity,” said Stanford Health Policy’s David Studdert, a professor of medicine and professor of law.

In an accompanying editorial alongside the research by a consortium of public health experts, the Global Burden of Disease 2016 Injury Collaborators, Studdert and his co-authors write:

“Injuries and deaths from firearms are increasingly part of modern consciousness, particularly in some countries. In the United States, gun-related massacres at schools, places of worship, workplaces, night clubs, and recreational venues have seared images of innocent victims in the minds of the populace. In the United States and elsewhere, acts of terrorism committed with firearms and other lethal means have changed the way people live, work, travel, and play.”

But Studdert and his co-authors — firearms and public health experts Frederick P. Rivara at the University of Washington and Garden J. Wintemute at the University of California, Davis — argue that the deaths from these headline-generating mass shootings and terrorist attacks are only a fraction of the public health burden of firearm-related murders and suicides.

“Mass shootings and terrorism perpetrated with guns are the most visible forms of firearm violence,” Studdert told SHP. “But most firearm deaths are private tragedies. They are homicides and suicides that occur behind closed doors, leaving families and communities devastated.”

 
 
 
 

The global burden of firearm mortality is highly concentrated, according to the research. In 2016, six countries in the Americas — Brazil, the United States, Mexico, Columbia, Venezuela and Guatemala — accounted for slightlymore than 50 percent of all deaths.

An estimated 32 percent of the deaths occurred in just two countries, Brazil and the United States, with Brazil accounting for one-fourth of all firearm homicides and the United States 35 percent of all firearm suicides.

“For individuals living in the United States, where the national policy debate has focused largely on interpersonal violence, the study provides a reminder of the importance of firearm suicide. In 2016, there were 2 firearm suicides for every firearm homicide, a margin that has widened over the past decade as suicide rates have increased and homicide rates have been relatively flat. Older white non-Hispanic men are at greatest risk of firearm suicide. Research and prevention efforts in the United States should proceed from a more inclusive definition of firearm violence.”

The authors believe more robust methods for estimating the number and distribution of firearms — as well as a better understanding of access — are critically important in determining which policies and prevention strategies are most effective and how best to implement them.

Studdert and his fellow researchers said research on firearm violence and public health has been impeded by the Dickey Amendment, the 1996 bill that mandated “none of the funds made available for injury prevention and control  at the Centers for Disease Control and Prevention may be used to advocate or promote gun control.”

“In the absence of this funding, several private foundations have stepped in to fill the void," they wrote. "However, real progress in addressing the vast public health problem that the Global Burden of Injury Collaborators document will depend on sustained action from governments in both research and policy.”

Malaria claims nearly half-a-million lives worldwide each year — and yet we still know so little about the immunology of the disease that has plagued humanity for centuries.

There were 216 million cases in 2016, according to the World Health Organization. Sub-Saharan Africa carries 80 percent of the global burden of the mosquito-borne infectious disease which devastates families, disrupts education, and promotes the vicious cycle of poverty.

It is particularly brutal to pregnant women, who are three times more likely to suffer from a severe form of the disease, leading to lower birthweight among their newborns and higher rates of miscarriage, premature and stillborn deliveries.

“Pregnant women and their unborn children are more susceptible to the adverse consequences of malaria, so we are working to investigate new strategies and even lay the foundation for a vaccine to prevent malaria in pregnancy,” said Prasanna Jagannathan, MD, an assistant professor of medicine who is this year’s recipient of the Rosenkranz Prize.

Jagannathan, an infectious disease physician who is also a member of Stanford’s Child Health Research Institute, said the $100,000 stipend that comes with the prize will allow his lab members to ramp up their research in Uganda. A member of the nonprofit Infectious Disease Research Collaboration in Kampala, his team is particularly interested in how strategies that prevent malaria might actually alter the development of natural immunity to malaria.

“With support from the Rosenkranz Prize, we hope to identify maternal immune characteristics and immunologic targets that are associated with protection of malaria in pregnancy and infancy,” Jagannathan said.

The Dr. George Rosenkranz Prize for Health Care Research in Developing Countries is awarded each year by the Freeman Spogli Institute for International Studies and Stanford Health Policy to a young Stanford researcher who is trying to improve health care in underserved countries. It was established in 2009 by the family or Dr. George Rosenkranz, a chemist who first synthesized cortisone in 1951, and later progesterone, the active ingredient in oral birth control pills.

“My father has held a lifelong commitment to scientific research as a way to improve the lives and well-being of communities around the world,” said Ricardo T. Rosenkranz, MD. “In particular, he has always sought to improve the health of at-risk populations. Dr. Jagannathan’s work offers the very sort of innovative ingenuity that characterized my father’s early research, as well as his vision towards the future.”

Jagannathan and his collaborators at UCSF and in Uganda are currently conducting a randomized control trial of 782 Ugandan women who are receiving intermittent preventive treatment with a fixed dose of dihydroartemisinin-piperaquine(or IPTp-DP), a medication that has dramatically reduced the risk of maternal parasitemia, anemia, and placental malaria. Their preliminary data suggests that among 684 infants born to these women, maternal receipt of IPTp-DP may lead to a reduced incidence of malaria in the first year of life.

“Having the discretionary support of the Rosenkranz Prize will allow us to generate some preliminary ideas from this trial that could lead to larger studies, to push this agenda further along,” Jagannathan said.

That agenda is to create a vaccine that targets pregnant women to prevent malaria both during pregnancy — but also potentially preventing malaria in infants, giving them a better start in life.

“We’re not the first ones to think of this, but we have the opportunity to test these hypotheses in incredibly unique settings, with really well-studied cohorts that have real-world implications in terms of what we find,” Jagannathan said. “I’m hopeful that the data that’s generated over the new few years will allow us to keep moving forward.”

Jagannathan has been traveling to Uganda for a decade to study malaria. He’s seen firsthand the relentless, gnawing impact the disease has on daily life.

“Before I went to Uganda I really didn’t understand the burden that malaria causes in communities — and it’s just incredible,” he said. His first study was on children aged 5 and under who had on average six episodes of malaria a year.

“They just get it over and over again, and the toll on society is enormous,” he said. The clinics are overwhelmed and a parent or sibling must miss work or school to stay home with that child.

Yet, in highly endemic settings, children eventually develop an immunity that protects against the adverse outcomes from malaria. If he and his colleagues can understand how pregnant women and children develop this clinical immunity to malaria, it could lead to better treatments and preventative strategies.

“If we understand the mechanisms that underlie naturally acquired immunity, that would offer some clues as to how we can develop a vaccine that actually allows either that immunity to occur more quickly or prevents us from developing immunity that allows for the parasite to persist without symptoms,” he said.

There is currently a malaria vaccine undergoing testing in Africa. The vaccine, known as RTS,S, was developed by GlaxoSmithKline and the PATH Malaria Vaccine Initiative, with support from the Bill and Melinda Gates Foundation. Decades in the making, four doses of the vaccine are required to reduce malaria infection in humans.

“It’s a remarkable vaccine in that it’s effective in the beginning, but the problem is that the efficacy wanes very rapidly,” Jagannathan said, noting that some studies show that beyond three years, the effectiveness drops to 15-20 percent.

“That’s the big issue and why people are really interested in trying to find new strategies and new approaches for a next-generation malarial vaccine,” he said. “That’s the overarching aspect of what motivates my work.”

Poor air quality is thought to be an important mortality risk factor globally1,2,3, but there is little direct evidence from the developing world on how mortality risk varies with changing exposure to ambient particulate matter. Current global estimates apply exposure–response relationships that have been derived mostly from wealthy, mid-latitude countries to spatial population data4, and these estimates remain unvalidated across large portions of the globe. Here we combine household survey-based information on the location and timing of nearly 1 million births across sub-Saharan Africa with satellite-based estimates5 of exposure to ambient respirable particulate matter with an aerodynamic diameter less than 2.5 μm (PM2.5) to estimate the impact of air quality on mortality rates among infants in Africa. We find that a 10 μg m−3 increase in PM2.5 concentration is associated with a 9% (95% confidence interval, 4–14%) rise in infant mortality across the dataset. This effect has not declined over the last 15 years and does not diminish with higher levels of household wealth. Our estimates suggest that PM2.5 concentrations above minimum exposure levels were responsible for 22% (95% confidence interval, 9–35%) of infant deaths in our 30 study countries and led to 449,000 (95% confidence interval, 194,000–709,000) additional deaths of infants in 2015, an estimate that is more than three times higher than existing estimates that attribute death of infants to poor air quality for these countries2,6. Upward revision of disease-burden estimates in the studied countries in Africa alone would result in a doubling of current estimates of global deaths of infants that are associated with air pollution, and modest reductions in African PM2.5 exposures are predicted to have health benefits to infants that are larger than most known health interventions.

Humanitarians in Crisis: Lessons from the Battle for Mosul, Iraq

The Battle of Mosul was one of the largest urban sieges since World War II. From October 2016 and July 2017, Iraqi and Kurdish forces fought to retake Iraq’s second largest city, which had fallen to ISIL in 2014. They were backed by U.S.-led coalition forces. More than 940,000 civilians fled during the siege, and thousands were injured as they sought safety.

As global health assistance for developing countries dwindles, a Stanford student working on her PhD in health policy has developed a novel formula to help donors make more informed decisions about where their dollars should go.

Donors have typically relied predominately on gross national income (GNI) per capita to determine aid allocations. But using GNI is problematic because it effectively penalizes economic growth. It also fails to capture contextual nuances important to channeling aid effectively and efficiently.

So Tara Templin, a first-year Stanford PhD student specializing in health economics, and her Harvard colleague Annie Haakenstad, have developed a framework that estimates funding based on needed resources, expected spending and potential spending into 2030. They believe the more flexible model makes it adaptable for use by governments, donors and policymakers.

“We've observed development assistance for health growth attenuate over the last seven years,” said Templin, who was a research fellow at the Institute for Health Metrics and Evaluation before coming to Stanford. “There are difficult trade-offs, and this entails honing in on the specific challenges and countries most in need.”

Their research published in the journal Health Policy and Planning outlines how their “financing gaps framework” can be adapted to short- or long-run time frames, between or within countries.

“Depending on donor preferences, the framework can be deployed to incentivize local investments in health, ensuring the long-term sustainability of health systems in low- and middle-income countries, while also furnishing international support for progress toward global health goals,” write the authors, who also are Stephen Lim of the University of Washington, Jesse B. Bump of Harvard and Joseph Dieleman, also at the University of Washington.

The authors developed a case study of child health to test out their framework. It shows that priorities vary substantially when using their results as compared to focusing mainly on GNI per capita or child mortality.

The case study uses data from the Global Burden of Disease 2013 Study, Financing Global Health 2015, the WHO Global Health Observatory and National Health Accounts. Funding flows are anchored to progress toward the U.N. Sustainable Development Goals’ target for reductions in the death rates of children under 5. More than six million children die each year before their fifth birthday, so the United Nations set a goal to reduce under-5 mortality to at least 25 per 1,000 live births.

To build their child health case study, the authors relied on a 2015 study that estimated the average cost per child-life saved is $4,205 in low-income countries, $6,496 in lower-middle income countries and $10,016 in upper-middle countries.

The framework considers three concepts. First, expected government spending is constructed from national health accounts, which are standardized financial reports from countries around the world. Second, ability to pay is estimated by looking at countries with similar levels of economic development and looking at associations with country investment in the health sector. Lastly, needed investment considers a health target, the country’s current health burden, and average costs to save children’s lives in each country.

“Our focus is on the gap between the resources needed to reach critical health targets and domestic health spending,” the authors wrote. “We highlight two facets of domestic health resources—expected spending and potential spending—as critical. While donor preferences may vary, basing aid allocation on expected or existing spending levels incentivizes countries to spend less on health. We therefore propose the use of potential spending, which is a measure of a country’s ability to pay, as the domestic resource benchmark.”

Instead of the gap between expected spending and need, their framework focuses on the gap between potential spending and the health resources needed to meet global health targets. In the framework, policymakers can choose which gap they want to target, since this decision can involve many factors.

“By focusing on that gap, donors can catalyze sustained domestic spending while also addressing the resource needs critical to reaching international health goals,” they wrote.

They then looked at 10 countries with the most need for additional child health resources. The gap between expected spending and potential spending was highest in Afghanistan, at 79 percent, and lowest in Cameroon, where expected spending exceeded potential spending.

“Fifty years ago, GNI was the best proxy for countries’ ability to finance their own development and health,” the authors wrote.

But today, more empirical data and technology are available, allowing donors to incorporate a broader set of health financing measures into their decision-making process.

“The flexible but targeted nature of our framework is critical in the current era of global health financing,” said Haakenstad, the lead author. “Our framework helps to ensure the poor and disadvantaged, the majority of which now reside in middle-income countries, are reached by development assistance and other public financing. This funding is critical to reducing death and disability and reaching global targets in health.”

At least 91 Americans die every day from an opioid overdose. The epidemic has claimed more than 300,000 lives since 2000 and is expected kill another half million over the next decade.

So perhaps it’s time to step up lawsuits against the drug manufacturers that sell the opioids to the tune of $13 billion per year, Stanford Health Policy’s Michelle Mello argues in a commentary in the current issue of The New England Journal of Medicine.

Mello, a professor of law and of health research and policy, and co-author Rebecca L. Haffajee, an assistant professor of health management and policy at University of Michigan School of Public Health, note that although heroin and illicitly manufactured fentanyl account for an increasing proportion of opioid overdoses, the majority of people who are addicted to opioids get hooked on prescribed painkillers.

While clinicians and health-care providers are trying to prescribe fewer opioids, Mello and Haffajee believe litigation is another crucial method to fight the crisis.

“The search for solutions has spread in many directions, and one tentacle is probing the legal accountability of companies that supply opioids to the prescription market,” the authors write.

The final report of President Trump’s Commission on Combating Drug Addiction and the Opioid Crisis details decades of aggressive marketing of oxycodone from 1997-2002 that led to a tenfold rise in prescriptions to treat moderate to severe pain. “To this day, the opioid pharmaceutical industry influences the nation’s response to the crisis,” the report said, noting the industry had sponsored some 20,000 conferences for physicians on managing pain with opioids while claiming their potential for addiction was low.

Mello and Haffajee argue that similar to the early cigarette promotions by Big Tobacco, opioid manufacturers have failed to adequately warn patients about addition risks on drug packaging and in their marketing campaigns.

“Some recent claims allege that opioid manufacturers deliberately withheld information about their products’ dangers, misrepresenting them as safer than alternatives,” they write.

Early attempts to bring class-action suits against opioid manufacturers have encountered procedural barriers. Judges typically find that proposed class members lack sufficiently common claims because of different circumstances surrounding opioid use and clinical conditions.

But the tide may be turning. There has been an uptick in litigation against Big Pharma since Purdue Pharma, the maker of the blockbuster painkiller, OxyContin, agreed in 2007 to pay $600 million to settle charges that it misled federal regulators, doctors, and patients about the drug’s risk of addiction and its potential to be abused.

“As the population harmed by opioids grows and more information about the population is documented, it becomes easier to identify subgroups with similar factual circumstances and legal claims — for example, newborns with neonatal abstinence syndrome,” they said.

Perhaps most promising, the authors write, is the “advent of suits brought against drug makers and distributors by the federal government and dozens of states, counties, cities, and Native American tribes.

“Because the government itself is claiming injury and seeking restitution so that it can repair social systems debilitated by opioid addiction, these suits avoid defenses that blame opioid consumers or prescribers,” they said. “They also garner substantial publicity.”

The government is borrowing from the playbooks used to sue tobacco and firearms companies, relying on four strategies:

  • Focus on the “public scourge” created by the opioid manufacturers due to their oversaturation of the market, arguing that opioids constitutes a public nuisance;
  • Paint the opioid companies’ business practices as deceptive;
  • Call out the manufacturers’ lax monitoring of suspicious opioid orders; and
  • Ask courts to make companies disgorge the “unjust enrichment” they have reaped at the government’s expense through their unfair business practices.

Two large settlements have occurred in state cases that included unjust enrichment claims, the authors note, although the pharmaceutical companies avoided admitting fault. The Commonwealth of Kentucky settled with Purdue Pharma for $24 million in 2015 over allegations that it had profited while Kentucky was left paying associated medical and drug costs of those who became addicted.

Earlier this year, drug wholesaler Cardinal Health Inc. agreed to pay $20 million to settle a lawsuit brought by West Virginia’s attorney general over accusations that it flooded the market with opioids in a state that now has the highest opioid overdose rate in the nation.

Such lawsuits have garnered a lot of media attention and contributed to pressure on the U.S. government to take action against the abusive practices of drug manufacturers and distributors.

“Win or lose, lawsuits that very publicly paint the opioid industry as contributing to the worst drug crisis in American history put wind in the sails of agencies and legislatures seeking stronger oversight,” Mello and Haffajee write. “Together, litigation and its spillover effects hold real hope for arresting the opioid epidemic.”

 

Listen to a podcast with Haffajee talking about the opioid crisis.

There is plenty of research on how the rapid warming of the planet is going to have growing adverse impacts on global economies, health, food supplies and natural disasters.

A new study now suggests that as temperatures continue to rise — particularly with more and more 90-plus-degree days — more fetuses and infants will experience economic loss by age 30.

“There is a growing body of evidence that finds that shocks to the fetus and young child — whether nutritional, environmental, economic or stress-related — have long-term consequences on health, education and economic outcomes throughout the life cycle,” said Maya Rossin-Slater, an assistant professor of health research and policy at Stanford Medicine and a faculty fellow at the Stanford Institute for Economic Policy Research.

Rossin-Slater published her study Dec. 4 in the Proceedings of the National Academy of Sciences, indicating early-life exposure to extreme temperatures is linked to potential losses in human capital. Her co-authors are Adam Isen, an economist with the U.S. Department of Treasury, and Reed Walker, an assistant professor at University of California, Berkeley.

The researchers used data from the U.S. Census Bureau’s Longitudinal Employer Household Dynamic Files, which contain information on adult labor market outcomes linked to county and exact date of birth. They looked at weather in counties in 24 states on any given day, and then measured how many days with average temperatures above 90 degrees a child born on that day in that county would have experienced during gestation and during the first year of life. They then compared the earnings of individuals who were exposed to different numbers of such hot days, but who were of the same race and gender, and born in the same county and on the same day of the year (but in different years).

Each day a fetus or infant experiences 90-plus-degree temperatures, Rossin-Slater and her co-authors found that he made $30 less a year on average, or $430 over the course of his lifetime. While that may not seem like a huge loss of income, the authors point out that their study is best understood from a population-level perspective rather than from an individual one.

“There is a lot of research already showing that extreme heat has immediate effects on labor market productivity and GDP,” she said. “What we are saying is that there is another wrinkle to this — that there can be consequences many years later, on cohorts who are still in the womb.”

Most Americans today only experience one day a year that is 90 degrees or hotter. But the Climate Impact Lab has indicated that if countries continue to take only moderate action on climate change, by the end of this century there will be about 43 such days a year.

So, if you multiple a $30 annual loss a day by 43 days, you come up with an average $1,290 a year — and compounded in large populations of pregnant women in hot climates.

“Prior research shows that exposure to extreme heat in utero leads to lower birth weight and increases infant mortality,” said Rossin-Slater, who is also a core faculty member at Stanford Health Policy. She said poor fetal and infant health could impact adult earnings in three ways: cognitive impairment, poor health that causes people to miss school or work, and less non-cognitive skill development such as self-control.

“With regard to exposure to heat specifically, fetuses and infants are especially sensitive because their thermoregulatory systems are not fully developed and they have less capacity to self-regulate when their bodies are exposed to extreme temperatures,” Rossin-Slater said.

Hot Zones and Air Conditioners

The obvious questions that arise from such research: What happens to the babies of women who already live in very high temperatures? And why not just ensure that all pregnant women have air conditioners, at least in the developed world where it would be more affordable?

Women in warm zones such as parts of Africa and South Asia, as well as U.S. cities like Phoenix and Washington, D.C., shouldn’t worry too much. The loss of income is relatively little and people living in hot climates may actually adapt over time to exposure to extreme heat.

“Our study is not saying that individual people should be doing something differently to avoid exposure to extreme heat,” Rossin-Slater said. “Instead, we think we are providing additional evidence for the possible population-level consequences of climate change and the projected increase in the number of days with extreme temperatures.”

And what about those air conditioners? The cohorts in the study are actually born in the 1970s, during a period of rapid expansion in air conditioning across American households. The researchers found the earning losses went away in areas where most people got air conditioners installed.

“If we think that there is something biological going on as a result of the fetus being overheated, then it makes sense that AC, which prevents the overheating, can mitigate this negative effect,” Rossin-Slater said.

But it’s important to recognize, she said, that air conditioners come with costs, both financial from the perspective of individuals and households who can and can’t afford such systems, and environmental from the perspective of the country or planet as a whole.

“So this is not a `free’ solution and any cost-benefit calculations related to climate change should take into account this adaption response,” Rossin-Slater said. “But we ought to think about what these results imply at the global level — in many countries that are much hotter than the United States and still don’t have AC. So if we are trying to understand global inequality and the impacts of climate change on developing countries, our results suggest that climate change could play a role in perpetuating global inequality across generations.”

Paul Wise watched as children ran around a playground attached to a health clinic at a displaced persons camp on the outskirts of Mosul — the northern city in Iraq once controlled by the Islamic State but now back in the hands of the Iraqi government.

The children had survived the Battle of Mosul, which had fallen to ISIS in 2014 but was retaken by the government forces and allied militias during a nine-month military campaign that ended in July. Many of the children suffer from physical and mental wounds and Wise wondered how they would recover with so little medical infrastructure.

Wise was part of a small delegation of physician-academics asked to evaluate a World Health Organization-led system to treat civilians injured in the Mosul fighting. Wise and his colleagues recently slipped into Mosul to visit field hospitals, review health care on the ground and determine whether there is a better way to distribute medical aid during armed conflict.

The visit left the Stanford Medicine professor of pediatrics and senior fellow at the Freeman Spogli Institute for International Studies with questions about health care, humanitarian ethics, and conduct of war: Are there better ways to deliver emergency medical care during the height of battle? How do relief workers maintain neutrality when embedded with government security forces? Has the system of financing humanitarian interventions — one that was essentially created during the Cold War — become dangerously outdated?

Answering these questions is the mission of a new health-and-security initiative at Stanford led by Wise, a core faculty member at Stanford Health Policy who has spent 40 years working to improve the health of children impacted by conflict. Much of his work has been in Guatemala through his Children in Crisis project, the first university-based program to address the needs of children in areas of unstable governance and civil war.

“In talking with the groups that are running these humanitarian efforts in Mosul, there was this uneasiness, this kind of disorientation with the way things are now,” said Wise. “It was a kind of recognition that humanitarian norms are changing, the health personnel and facilities are at greater risk; the financial gap between humanitarian need and humanitarian capability is growing; and the old way of financing humanitarian intervention is inadequate, archaic.”

 

 

An Interdisciplinary Approach

Wise believes academics are well suited to help resolve these humanitarian conundrums.

“So we are going to move ahead and try to bring all the players together to reconsider this global challenge. Here at Stanford, we have the capacity to draw upon remarkable resources,” he said.

The new biosecurity initiative led by Stanford Medicine physician and FSI senior fellow, David Relman, together with world-renowned political scientists, security specialists, computer scientists and health policy experts will “attempt to craft new strategies for the provision of critical services to populations affected by conflict and political stability.”

The initiative will collaborate with other institutions such as Johns Hopkins, UCSF, Harvard, and the American Academy of Arts and Sciences. It will also seek the engagement of partners committed to providing humanitarian services, including WHO, the U.N. High Commissioner for Refugees, Doctors Without Borders and the International Committee of the Red Cross.

“The voice of communities impacted by war should also be an essential element in this ambitious effort,” Wise said. “To break new ground, we’re going to have to do things differently; the health strategies need to take into consideration fundamental understanding of the political dynamics. But we have a special opportunity here at Stanford because we take an interdisciplinary approach.”

Children of War

Most of the children Wise saw will never be the same, he said, nor the humanitarian workers who risked their lives to treat them, their families, and fighters from all sides of the battle to oust the Islamic extremists from the city on the Tigris River.

“I look at these little kids with horrendous emotional trauma and PTSD, and I think to myself, it’s the collision of all these questions playing out within a 50-square-meter little playground,” he said. “It’s these broader, strategic and ethical questions that are really profound. And as a pediatrician who is dedicating the last phase of my career to these questions of security and the political dimensions — I have to engage on all of these levels. That’s not easy.”

Wise traveled with WHO officials, as well as Paul Spiegel, a physician who leads the Center for Humanitarian Health at Johns Hopkins Bloomberg School of Public Health; Adam Kushner, a trauma surgeon affiliated with Johns Hopkins; and Kent Garber, a surgical resident at UCLA and research associate at Johns Hopkins.

Spiegel also believes academics are uniquely positioned to help assess the current system of responding to medical crises during conflict.

“I believe that we can bring objectivity and rigor to analyzing and evaluating important and innovative responses, such as the trauma response by WHO and others in Mosul,” Spiegel said. “Humanitarian organizations are often busy responding quickly to rapidly changing situations; they don’t always have the luxury of time to do what academic humanitarians can do.”

Making the two-hour drive from Erbil to Mosul in armored, bulletproof SUVs provided by the United Nations, they slipped into field hospitals to meet with Iraqi physicians and medical teams with the humanitarian agencies.

Wise, who was able to take a few photos and video on his smartphone, described the devastation on the ground, noting that not since the siege of Leningrad has a city of this size experienced such street-by-street fighting. In large parts of the city, virtually every building was bombed or bulleted. It will take years to clear the rubble and rebuild.

“It’s just a remarkable story of tragedy and resilience,” he said.

Since the city was not long ago controlled by ISIS, the field hospitals are still surrounded by massive concrete barricades and tactical trucks stationed outside with mounted machine guns.

The team found that at the height of the battle for Mosul, there was tremendous pressure to treat injured civilians and discharge patients very quickly, due to the lack of medical infrastructure and personnel and the continuous wave of new injuries coming in.

“The charge for us was to evaluate the system and how well it worked, what ways could it be improved, how many lives that it saved,” Wise said. “One of the concerns, for example, was that in order to put in medical people that close to the frontline, you have to give them some kind of security. This raised issues among the humanitarians about their need for independence and neutrality, since you’re essentially embedding them with Iraqi security forces.”

Epidemiology and Ethics

 

“We are looking at the technical issues and the epidemiologic issues, but also dealing with the ethical issues and their implications,” he said.

They intend to write an internal report and then publish their findings in a major medical journal, to get the word out about the issue and gain support for ongoing collaborative work. They’re looking to partners like the American Academy of Arts and Sciences, which recently devoted an entire issue of its journal, Daedalus, to the factors and influences of contemporary civil war. One of the essays in that issue by Wise and his Stanford colleague, Dr. Michele Barry, who directs the Center for Innovation in Global Health, talks about the threat of a global pandemic as a potential byproduct of the 30 ongoing civil wars around the world.

“We’re trying to get the report completed quickly because the model of trauma care for civilians in Mosul is a new model and could be implemented in other combat areas, like the fighting in Syria and other places in Iraq,” Wise said.

Wise worries some see Stanford University as an insulated Silicon Valley institution in a beautiful setting and not always engaged in the real world.

“Well, this is about as engaged in the real world as you can get — this is Stanford moving and doing things out there, not just sitting around in seminar rooms. Sometimes you need to get close to the front lines to save lives,” he said.

When asked what surprised him during this trip to Mosul, Wise smiled.

“I’m sort of old and I’ve seen a lot of the world and not a lot surprises me anymore,” he said. “But it was a reminder of how desperate are the lives of millions of people — that we could do so much more. It’s a reminder of just how fragile physical security really is in this world."
