A Virtual Stroll through the 2021 Bass Connections Showcase

Sticky post

Posters, presentations, and formalwear: despite the challenge of a virtual environment, this year’s annual Fortin Foundation Bass Connections Showcase still represented the same exciting scholarship and collegiality as it has in years past.

While individuals could no longer walk around to see each of this year’s 70+ teams present in person, they were instead able to navigate a virtual hall with “floors” designated for certain teams. With labels on each virtual table, it almost mimicked the freedom of leisurely strolls down a hall lined with posters, stopping at what catches your eye. Three sessions were held over Thursday, April 15 and Friday, April 16.

The beginning of each session featured five-minute “lightning” presentations by a diverse set of teams, representing the range of research that students and faculty participated in.  One such presentation was lead by Juhi Dattani ’22 (NCSU) and Annie Roberts ’21, who covered research generated by their team, “Regenerative Grazing to Mitigate Climate Change.” The team was an inter-institutional project bringing together UNC, NCCU, NCSU, and Duke. And as they aptly summarized, “It’s not the cow, but how.” Cows can help fight instead of contribute to the climate crisis, through utilizing regenerative grazing – which is an indigenous practice that has been around for hundreds of years – to improve soil health and boost plant growth.

Research is not just relegated to the physical sciences. Brittany Forniotis, a PhD candidate ’26, and Emma Rand ’22 represented the team “Mapping History: Seeing Premodern Cartography through GIS and Gaming.” Their team was as interdisciplinary as it gets, drawing from the skills of individuals in everything from art history to geography to computer science. They posited that mapmakers use features of map to argue how people should see the world, not necessarily how they saw the world. To defend this hypothesis, they annotated maps to record and categorize data and even converted maps to 3D to make them virtual, explorable worlds. The work of this team enabled the launch of Sandcastle, which aims to “enable researchers to visualize non-cartesian, premodern images of places in a comparative environment that resembles the gestural, malleable one used by medieval and early modern cartographers and artists.”

The work of the team added to a project launch of Sandcastle.

Sophie Hurewitz (T ’22) and Elizabeth Jones (MPP ’22) presented on behalf of the “North Carolina Early Childhood Action Plan: Evidence-based Policy Solutions”, Their recommendations for alleviating childhood food insecurity in North Carolina as outlined by the North Carolina Early Childhood Action Plan will provide a roadmap for NC Integrated Care for Kids (NC InCK) to consider certain policy changes.

One of the most remarkable parts of Bass Connections is how it opens doors for students to pursue avenues and opportunities that they may have never been exposed to otherwise. Hurewitz said that “Being a part of this team led me and a team member to apply for the 2021 Bass Connections Student Research Award, which we were ultimately awarded to study the barriers and facilitators to early childhood diagnosis of Autism Spectrum Disorder (ASD) among Black and Latinx children in North Carolina.” In addition to the award, Hurewitz and fellow team member Ainsley Buck were able to present their team’s research at the APA Region IV Annual Meeting.

The 2019-2020 team, pre-COVID.

From gene therapy for Alzheimer’s disease to power grids on the African continent, this year’s teams represented a wide range of research and collaboration. Erica Langan ’22, a member of the team “REGAIN: Roadmap for Evaluating Goals in Advanced Illness Navigation”, said that “For me, Bass Connections has been an extraordinary way to dive into interdisciplinary research. It’s an environment where I can bring my existing skills and knowledge to the table and also learn and grow in new ways.” This interdisciplinary thinking is a hallmark of not just Bass Connections, but Duke as a research institution, and it’s clear that this spirit is alive and well, even virtually.

Black Americans’ Vaccine Hesitancy is Grounded in More Than Mistrust

Covid-19 is considered a “general pandemic,” but its impacts have been disproportionate along the lines of race and ethnicity. Though vaccines may serve as our best chance to put an end to Covid, the problem of vaccine hesitancy amongst Black people in the U.S. is particularly pervasive and grounded by more than simple mistrust.

Gary Bennett (Ph.D.) discussed the issue of complex determinants of vaccine hesitancy among Black Americans Monday, April 5. Bennett is a Professor of Psychology, Neuroscience, Global Health, and Medicine at Duke, as well as director of Duke Digital Health and Vice Provost for Undergraduate Education.

Gary Bennett, Ph.D.

“At the end of the day, we are dealing with an issue that demands pragmatic attention,” Bennett said, “How do we get shots in arms?” It turns out, the answer is quite complex and historically confounded.

While Black people have experienced much higher burdens from Covid-19 despite contracting the disease at a similar rate to whites, they have been disproportionately vaccinated at lower rates than white people.

“Access matters and it matters a lot,” Bennett said. One clear example of decreased access for Black Americans is that fewer vaccination sites are located in areas with high concentrations of Black people.

However, Bennett said, access does not simply equal place. “How much friction are you creating in this process?” he prompted, pointing to examples of complicated registration systems, inadequate public transportation to vaccine sites, or overall distance from a location. All of these factors already limit who is able to access vaccinations without the added influences of reduced vaccine uptake due to vaccine hesitancy.

A slide from Dr. Bennett’s presentation which outlines the plethora of impactors on access.

Vaccine hesitancy was listed by the World Health Organization as a top 10 global threat in 2019, when vaccines were preventing 2-3 million deaths per year in the pre-Covid era. Though Bennett said that vaccine hesitancy “has been with us for a long time,” there “are real consequences” to continued reluctance and refusal to get vaccinated with heightened risks due to the nature of the pandemic.

Bennett said that many claims around hesitancy blame communities for their inability to access vaccines, but this fails to consider or to change the underlying behaviors that drive hesitancy. Bennett outlined these underlying drivers as 1) mistrust, 2) social norms, and 3) understandable uncertainties.

A slide from Dr. Bennett’s presentation showing the unequal distribution of vaccination sites in Atlanta GA in predominantly white areas.

“It’s not just mistrust of the medical system, it’s mistrust of institutions,” Bennett said, “There’s a lot of reasons for [Black people] to mistrust institutions.” The murder of George Floyd stands as one poignant contemporary example, but “Tuskegee [still] looms large in the minds of Black Americans.” The Tuskegee experiment exploited 600 Black men working as sharecroppers who had syphilis by knowingly withholding treatment and simply seeing what happened to their bodies as a result of the disease for over 40 years.

This experiment was not the first of its kind: Whole body radiation was tested on Black people. Fistula surgery was developed on enslaved Black women by the “father of modern gynecology.” The immortal cells of Henrietta Lacks, a Black woman, have been used far and wide to advance science after a sample of her cancerous cervix was unknowingly stolen from her. Modern studies have also shown how different implicit biases of Black patients shape their treatment outcomes due to skewed physician perceptions.

The capital riot, the murder of George Floyd, and the Jim Crow Era all exemplify the pervasive institutionalized racism that erodes Black trust in U.S. institutions of all kinds.

Our social networks are also vitally important to influencing our feelings about receiving the Covid vaccine. In Black communities, Bennett said, fewer people in their networks have gotten vaccinations and those who have received vaccines are less vocal about it leading to a collective lack of interest in receiving vaccinations.

These two factors, paired with understandable uncertainties about the side effects of the vaccine or potentially getting Covid itself, generate the need to change our approaches to vaccine hesitancy and increased uptake amongst Black communities in the U.S.

White people have been disproportionately vaccinated over all other racial/ethnic categories in the U.S.

To do this we need to lead with empathy and appreciate the fact that changing attitudes towards vaccines is a process. “Shaming people is bad,” Bennett said. “Stigmatizing people will actually lead to the converse of what we expect.”

Over time, we can work to correct misconceptions, contextualized uncertainties, and share stories rather than statistics to push people further from vaccine refusal and closer to vaccine demand.

And when more Black Americans are ready, “vaccination should be an easy choice.” By implementing opt-out policies, rather than opt-in and by taking more direct actions like making vaccination appointments for people, Covid vaccines may indeed be the key to ending the pandemic – in an equitable and proportionate way.

A Patient’s and Doctor’s Perspective on Narrative Medicine

Sticky post

When asked about the process of writing her memoir, Dana Lorene Creighton paused in thought.

“It’s like spilling your guts to a lined composition notebook,” she said.

On Tuesday, March 30th, Creighton was joined by Dr. Sneha Mantri, her neurologist at Duke and director of the Trent Center’s Program in Medical Humanities, for Narrative Medicine: A Patient’s Perspective – a conversation about the impact of narrative medicine and the journey to her memoir, A Family Disease: A Memoir of Multigenerational Ataxia.

Creighton, who has an MS in exercise physiology and has spent her career involved in clinical research and community health at both UNC-Chapel Hill and Duke, has spinocerebellar ataxia, a hereditary neurodegenerative condition characterized by a lack of muscle coordination. The illness is commonly visible through slurred speech, stumbling, falling, and incoordination due to damage to the cerebellum – the part of the brain that controls muscle coordination.

As Creighton described, prior to writing her book in her late forties, she hadn’t successfully communicated to anyone the impact of ataxia on her life. And so, her memoir was organically born, but as Creighton says, “it was hard for me to type as fast as I was thinking, and that lasted for several months.”

It took Creighton a couple of years just to write the foundation of the book, which draws on neuroplasticity research, personal memories, and medical records to highlight the importance of storytelling in deriving meaning from illness. She spent the next two years after that re-shaping the arc, drawing on a wealth of her own experiences as well as decades of journaling that had left her with a meticulous set of notes.

As both Creighton and Dr. Mantri emphasized, writing is a deeply cathartic exercise as well as a way to share significant personal narratives. This is especially true in a field such as medicine, where people are so often treated as an illness or statistic rather than a human being.

Narrative medicine was coined as a term by Dr. Rita Charon in her book Narrative Medicine: Honoring the Stories of Illness, to refer to “medicine practiced with the narrative skills of recognizing, absorbing, interpreting, and being moved by the stories of illness . . . . Along with their scientific expertise, doctors need the expertise to listen to their patients, to understand as best they can the ordeals of illness, to honor the meanings of their patients’ narratives of illness, and to be moved by what they behold so that they can act on their patients’ behalf.”

While the recognition of patient and doctor narratives has been around for many years, it was not until fairly recently that narrative medicine emerged as a field of knowledge that doctors could educate themselves in.

Dr. Mantri is familiar with the benefits of narrative medicine from a clinical perspective, holding an M.S in Narrative Medicine from Columbia University and being a leader of various narrative medicine initiatives at Duke, both with doctors and medical students.

According to Dr. Mantri, elucidating these narratives is crucial to understanding that at the end of the day, doctors and patients work to navigate challenges of illnesses with different perspectives. It’s necessary to hear the story of a patient as well as understand the story of a clinician. Only then can doctors work to find moments of alignment between these two perspectives, resulting in care that is more patient-centered.

From the patient perspective, Creighton remarks that a chapter in her book delves into narrative medicine, even though at the time she had no idea what it was. As she learned more about the field, though, it became clear just how integral narrative medicine was to her experience processing and coming to terms with her ataxia. Prior to taking a class on narrative medicine, she assumed that it wouldn’t be a positive experience. But years later, she credits the process of writing her memoir with allowing her to move on, in many ways, from the hold her illness had on her.

Creighton also pointed out that as humans, “we want the same things – to feel heard and to make meaningful connections with others who can potentially help us navigate whatever condition we’re going through.”

To that end, Dr. Mantri and Creighton both referred to several resources that can help people with illnesses find communities of other individuals with the same illness, in order to find the type of solidarity and understanding promoted by sharing experiences. One such resource is PatientsLikeMe, where individuals can ask questions and exchange tips on their specific illness with others going through similar struggles.

PatientsLikeMe

Finally, Creighton was asked about the things she’d like clinicians to know from her perspective as a patient. She described the disconnect that she had often felt, not only with doctors but with therapists and counselors, stemming from a feeling that the help she was offered often did not meet her where she was. In brainstorming ways to mitigate this gap, both Dr. Mantri and Creighton pointed to a need for doctors to focus on a patients’ needs and desires, and a need for patients to advocate for themselves.

As the conversation concluded, Creighton emphasized the importance of being seen as a human rather than a victim of a disease. Spinocerebellar ataxia is neurodegenerative, meaning that symptoms progressively get worse. But as Creighton remarked: “Losing my abilities is going to happen. Losing my abilities doesn’t change the human that I am.”

The SolarWinds Attack and the Future of Cybersecurity

Cybersecurity is the protection of computer systems and networks in order to prevent theft of or damage to their hardware, software, or electronic data. While cybersecurity has been around since the 1970s, its importance and relevance in mainstream media as well as politics is growing as an increased amount of information is stored electronically. In 1986, approximately 1% of the world’s information was stored in a digital format; by 2006, just twenty years later, this had increased to 94%.

Cyber Hacking has also become more prominent with the advent of the Digital Revolution and the start of the Information Era which began in the 1980s and rapidly grew in the early 2000s. It became an effective political form of attack to acquire confidential information from foreign countries. 

In mid-December of 2020, it was revealed that several U.S. companies and even government agencies were victims of a cyberattack that began in September of 2019. 

The Sanford School of Public Policy hosted a leading cybersecurity reporter Sean Lyngaas to lead a discussion on the national security implications of the SolarWinds hack with Sanford Professor David Hoffman as well as Visiting Scholar and Journalist Bob Sullivan. Lyngaas graduated from Duke in 2007 and majored in Public Policy at the Sanford School. 

Lyngaas did not have a direct route into cybersecurity journalism. After completing his Masters in International Relations from The Fletcher School of Law and Diplomacy at Tufts University he moved to Washington D.C. to pursue a career as a policy analyst. However, at night when he was not applying for jobs he began pitching stories to trade journals. Despite not being a “super technical guy” Lyngaas ended up becoming passionate about cybersecurity and reporting on the increasing amounts of news surrounding the growing topic. Since 2012 Lyngaas has done extensive reporting on cybersecurity breaches and recently has published several detailed reports on the SolarWinds incident. 

Sean Lyngaas

The SolarWinds attack is considered one of the most impactful cybersecurity events in history as a result of its intricacy and the number of government and private sector victims. Lyngaas explained that most people had not heard of SolarWinds until recently, but the company nevertheless, provides software to a multitude of fortune 500 companies and government agencies. One of the software products they sell is Orion, an IT performance monitoring platform that helps businesses manage and optimize their IT infrastructure. The Hackers infiltrated Orion’s update software and over several months sent out malicious updates to 18,000 companies and government agencies. Among the victims of this espionage campaign were the U.S. Justice Department and Microsoft. As a result of the campaign, countless email accounts were infiltrated and hacked.

“A perfect example of someone robbing a bank by knocking out the security guard and putting on his outfit to have access.” 

Bob Sullivan

Sullivan added that this hack is particularly concerning because the target was personal information whereas previous large-scale hacks have been centered around breaching data. Additionally, SolarWind’s core business is not cybersecurity, however, they work with and provide software to many cybersecurity companies. The attack was revealed by FireEye, a cybersecurity company that announced they had been breached.

“FireEye got breached and they are the ones usually investigating the breaches”

Sean lyngaas

This situation has prompted both those involved in the cybersecurity industry as well as the public to reconsider the scope of cyberhacking and what can be done to prevent it.

“Computer spying by nation states has been going on for decades but we talk about it more openly now.” Lyngass stated. 

Lyngaas added that the public is now expecting more transparency especially if there are threats to their information. He feels we need to have better standards for companies involved in cyber security. Solarwinds arguably was not using cybersecurity best practices and had recently made price cuts which may have contributed to their vulnerability. Hoffman explained that SolarWinds had been using an easy-to-guess password to their internal systems which allowed hackers access to the software update as well as the ability to sign a digital signature. 

“We are not going to prevent these breaches; we are not going to prevent the Russians from cyber espionage.” Lyngaas stated

However, he believes by using best practices we can uncover these breaches earlier and react in a timely manner to reduce damage. Additionally, he thinks there needs to be a shift in government spending in terms of the balance between cyber defense and offense. Historically, there has been a lack of transparency in government cyber spending, however, it is known that there has been more spent on offense in the last several years.

Changes are starting to be made in the cybersecurity landscape that hopefully should aid in reducing attacks or at least the severity of their impacts. California recently created a law centered around publicizing breaches which will increase transparency. The panelists added that the increasing amount of news and information available to the public about cybersecurity is aiding efforts to understand and prevent it. President Biden was openly speaking about cybersecurity in relation to protecting the election from hackers and continues to consider it an urgent issue as it is crucial in order to protect confidential U.S. information. 

As Lyngaas explained, it is practically impossible to completely prevent cyber attacks, however, through increasing transparency and using best practices, incidents like the SolarWinds hack will hopefully not have effects of the same scale again.

Widespread Vaccination Will Depend on Faith in Science

Two Covid vaccines have been approved via Emergency Use Authorizations. But, many scientists, health professionals, and regulatory members alike are left wondering how to best ensure the American and global public opt-in to getting vaccinated.

During Friday, December 18th Coronavirus Conversation hosted by the Duke Initiative for Science & Society, honored guests Anthony Fauci (M.D.) and Alan Alda discussed the restoration of faith in public science agencies, moderated by Hank Greely (J.D.). You can view the entire program here (40 min.)

Dr. Fauci has become a household name this year as a member of the White House Coronavirus Task Force but is more widely regarded as one of the most trusted U.S. medical figures and has been director of the National Institute of Allergy and Infectious Disease since 1984.

Mr. Alda, though popularized through his acting career, has been a life-long advocate for science. He hosted PBS show “Scientific American Frontiers,” founded the Alan Alda Center for Communicating Science at SUNY Stony Brook, and recently released a podcast titled “Soldiers of Science.” At Stanford, Mr. Greely is director for the Center for Law and Biosciences and the Program in Neuroscience and Society, as well as a Professor of Law.

Greely asked about the public’s current level of trust for science and what must be done to get it “where it should be.” Alda said that there “seems to be this awful fall off of trust in science … at the worst possible time.” But Dr. Fauci pointed out that we have seen the evolution of lack of trust in science over the previous couple of years. The pandemic fell in the middle of extreme American divisiveness, he said, leading to individuals “developing their own set of facts instead of interpreting [actual] data that exists.”

Alda and Fauci both emphasized the need for transparent and clear scientific communication as a main tactic for increasing public faith in science. This includes use of the words “I don’t know,” particularly in response to the question of vaccine longevity, a question Dr. Fauci said will be answered “in due time.”

Alda said scientific communicators should “communicate with audience[s] with respect … with personal contact where trust builds up more quickly.” He pointed out that this means communicators must become more familiar with their audiences, what terms would be best to use, and what their audiences are “ready to hear.” Dr. Fauci added that when someone is “speaking science” to any group, the objective should not be to “impress the [audience] as to how smart [they] are.” The two major objectives laid out by Fauci: 1) Know the audience and 2) know your message, avoiding granularity and inaccessible language.

Greely interjected that the though all three panelists agree on trust in science, they were three white guys “of mature years.” He continued to say that, “One of the saddest ironies [is that] people getting hammered hardest by [Covid] tend to be people from racial and ethnic minorities … those are also [the same] groups of people that have understandable historic reasons to have less trust [in scientific agencies].” How do we reach these groups?

To do this, Dr. Fauci proposed that we need to get messengers for vaccination to “to look like and understand to whom [we] we are delivering the message.” Leaning into an idea by Alda – that we should get celebrities and widely-respected and admired individuals to get vaccinated on television – Fauci described how Surgeon General Jerome Adams got publicly vaccinated Friday morning.

Adams also delivered a message to his “Black and Brown sisters and brothers” in support of vaccination. Dr. Fauci believes more positive messaging like this will be effective. Alda reinforced that “we can’t guess about the people we’re trying to talk to.” We have to know about their biases and cause for hesitancy in order to meet them where they are, as well as address their concerns in genuine, non-condescending ways.

Alda also proposed that individuals snap a quick shot of themselves getting vaccinated and post it to social media as a #vaccie – a play on the #selfie sensation – which Greely said was “brilliant.”

Alda and Fauci concurred that the most powerful proponents of restoring faith in science may lie in the impact of individual civilians who share their trust in and compliance with vaccination amongst family and friends. Fauci said individuals should not “underestimate the impact that they have in their own immediate environment.”

Sandra Lindsay, an Intensive Care Unit nurse in New York, was one of the first people in the U.S. to receive the Pfizer Covid vaccine.

This impact could be either positive or negative, though, as Alda pointed out the problem with social media algorithms. While working on “Soldiers of Science,” he learned that social media sites are designed to “keep your eyeballs on the screen” as long as possible. This means that social media sites keep “showing you what you want to see,” which is your own bias and affirmation that your ideas are correct. If #vaccie starts trending, this might provide necessary momentum for widescale vaccine uptake.

However, because we have become “addicted to [our] bias” and convinced “over and over again that only our view is right,” according to Alda, we must work intentionally to see commonalities across seemingly alienating lines. Reflecting on his work with AIDS, Dr. Fauci suggested that we take what scientific communicators and regulatory bodies learned during that time. “What do we all want?” Fauci said, ”And how do we get there in a way that is synergistic [instead of] opposing?”

In his parting thoughts, Alda stated simply that “science will save us.” It has and will continue to allow us to “counterattack the attacks we get from our mother nature.” Dr. Fauci said that in dealing with the current pandemic, “biomedical research and science has given us something that just a decade ago would have seemed unimaginable.”

“When this is over, and it’s going to be over,” Fauci said, “We’re [going to] look back and say, ‘It was science that got us out of this, pure science.’”

Greely said we have learned a lot about science communication this year – invaluable information that we must carry forward with us.

I, like so many others around the world, can’t wait for my turn to get the Covid vaccine and to kiss 2020 and the pandemic goodbye.

Trust in Gynecology: The Impact of Race & Socioeconomic Status in Women’s Health

Nikki Mahendru’s mother didn’t go to the gynecologist for 45 years — and when she did, she regretted it. Ms. Mahendru felt “decades of anxieties and hesitancy reduced to five minutes of brisk interaction with her provider,” and left convinced that the “realm of women’s health was just not for her.” According to Nikki, a Duke University undergraduate, her mother’s “trust in the system was lost.” 

Mahendru joined Dr. Megan Huchko, the director of the Duke Center for Global Reproductive Health, and Dr. Chemtai Mungo, a Fogarty Global Health Fellow and OB-GYN doctor, on the Center for Global Women’s Health Technologies’ October 20 panel “Impact of Race and Socioeconomic Status in Women’s Health and Gynecology.” The panel was moderated by Ashley Deans and Alexandria Da Ponte.

Mahendru went on to detail an experience she had in the clinic with Carmen, a patient who spoke only Spanish and was also new to the gynecologist. The medical translator and Mahendru learned her story: she had been in pain for a year but had kept quiet due to money problems, had worked most of her life to send her kids to college, and was learning English via Rosetta Stone. With the details of Carmen’s story and an “equitable working relationship,” Mahendru and the translator could relay Carmen’s previous history to her provider. But Carmen’s provider knew only of her condition. 

Mahendru thinks gynecology done right has the potential to help women love their bodies and take care of their health, but gynecologists must earn the trust of their patients: “Acts of listening help bridge disparities.”

Dr. Huchko stated that throughout history, a male-dominated healthcare landscape saw the depiction of menses as ‘dirty,’ terms like ‘hysteria,’ and an overall lack of female control. The “father of gynecology” James Marion Sims exploited Black women in his development of the field, using unanesthetized slaves as subjects of experimentation. In general, Dr. Huchko sees a trend: “The lessening or decentering of women in women’s health corresponds to more discrimination.” In addition to the decentering of women, Dr. Huchko said that structural and individual factors “produce outcomes that prevent women from getting the care they need.” Like Mahendru, she identified trust as a central issue.

Dr. Megan Huchko, MD, MPH, is the director of the Duke Center for Global Reproductive Health

Dr. Huchko cited an experience in which she bore witness to the unattended consequences of racial bias in medicine. In Niger to repair women’s fistulas, which occur due to lack of postpartum care, Dr. Huchko felt she was attending to the downstream symptom of a much broader issue. She felt uncomfortable when the urogynecologist on her team ignorantly praised Sims without acknowledging his problematic history. Then, she saw this ignorance firsthand. 

Making a false assumption about the nature of the case, Dr. Huchko’s team chose to operate on a woman with a mass in her bladder. During the surgery, they realized the mass was a malignant tumor. With an unbiased eye and a complete exam and workup, this would have been clear. But because the team was looking at these women as “one-dimensional,” a woman with stage 4 cancer was subjected to a very invasive surgery that worsened her quality of life. 

Dr. Huchko experienced a similar lack of structural competency during her residency, where colleagues openly racially profiled people and overtly discussed disparities in pain tolerances among different ethnicities. Since then, “things have changed,” and she embraces this new culture of “being patient centered, exploring our own biases, and [having] zero tolerance for racial profiling.” She stresses the need for personal education and accountability alongside systemic change. Eventually, this will lead to women feeling “respected, seen, and heard.”

Coming to the US from Kenya, Dr. Mungo quickly came to appreciate the “sheer magnitude” of structural racism and its impact on health and healthcare. Dr. Mungo explained that “mutually reinforcing systems of disadvantage” for people of color, such as food deserts, are both the result and cause of healthcare disparities and result in enduring legacies of disadvantage.

Dr. Chemtai Mungo, MD, MPH, is a Fogarty Global Health Fellow and OB-GYN doctor

Dr. Mungo also observed that with healthcare in the US being so economically driven, the best care is often directed at those with racial and socioeconomic privilege. When she worked in a high resourced (read: white, wealthy) hospital, access to uterus-saving equipment such as interventional radiology meant that she only did one hysterectomy in four years. Doctors at the hospital also came in on weekends to get a person with cancer into the OR immediately.

Now, working at a “safety net hospital,” Dr. Mungo sees a stark difference. With non-existent interventional radiology and more part-time, “less invested” employees, Dr. Mungo has done three hysterectomies in three years — a 75% increase — and sees patients with time-sensitive conditions wait much longer before surgery. This “separate and unequal access to resources” is a cause for concern. 

Dr. Mungo also stressed the need to make practices “safe places” for patients of color by increasing minority representation. Dr. Mungo explained that while Black physicians make up only 5% of doctors and 3% of faculty, there is strong evidence that patients who are cared for by someone of their own race or ethnicity have better outcomes. “We live in a racist society,” Dr. Mungo stated, “so we need specific anti-racist policies.” 

Dr. Mungo also acknowledged that healthcare providers work within “templates” like 15 minute appointments, and posed the closing question, how can we make patients feel safe and heard within the constraints of modern medicine? 

Answering questions from the audience, Dr. Mungo and Huchko discussed medical algorithms that are based on race, like the VBAC calculator and GFR. 

Dr. Mungo indicted these algorithms as “an example of how institutionalized some [racial] biases are.” There is “no concrete evidence” on why these corrections for race — which typically act to reduce the probability of success for a procedure or favorability of an outcome — exist. Dr. Mungo would urge providers “not to stop at, ‘well, African Americans have an increased risk of diabetes.’ Ask why. Have them explain food deserts… and structural and environmental racism.”

Dr. Huchko stated that giving aspirin throughout pregnancy reduces preeclampsia, and is thus traditionally offered based on risk factors for preeclampsia, like low socioeconomic status and African American race. Sometimes, healthcare providers may not be able to address these risks without the acknowledgement of race as a risk factor. Dr. Huchko is right, African American women are at a higher risk for preeclampsia, and ignoring this correlation would probably do more harm than good. 

But per Dr. Mungo’s appeal, providers must interrogate these associations more deeply — and be ever anti-racist in their efforts — if they are to create the safe spaces and trusting relationships that Mahendru, Dr. Huchko, and Dr. Mungo each hope to see.

The evolutionary advantage of being friendly

We’ve all heard the term “survival of the fittest,” which scientist Charles Darwin famously coined to explain how organisms with heritable traits that give them an advantage — such as avoiding predators or beating out others for the chance to mate — are able to survive and pass on these advantageous traits to their offspring.

In his talk with ClubEvMed last Tuesday, Brian Hare of Duke Evolutionary Anthropology explained key points from his new book that he co-authored with his wife and research partner, Vanessa Woods, entitled Survival of the Friendliest: Understanding Our Origins and Rediscovering Our Common Humanity

Image from Penguin Random House

The term “fittest” is often associated with animals who are physically stronger or of more value than others, but being “fit” can also include an organism’s ability to communicate well with others in its group, which can provide an evolutionary advantage. For example, more social animals can form alliances with each other and protect each others’ young, so the whole population stays stronger in terms of number.

Hare cited a comparison between chimpanzees and bonobos, both of which have the potential for infanticide by aggressive males in a group. However, bonobos have zero cases of infanticide because female bonobos are able to communicate well and form alliances to protect each others’ young from aggressive males. Since the high cost of aggression for males outweighs the benefit, the males are friendlier, and the young bonobos survive. While this is a specific case with wild animals, other species have adopted social skills as a method of survival through domestication or self-domestication. 

Image from brianhare.net

Hare referred to dogs as “exhibit A” of survival of the friendliest via domestication, because humans have bred dogs that are more playful, approachable and patient for centuries. Dogs are exceptionally good at understanding, responding to and communicating with humans as a result of domestication. Hare also explained one Russian study in which they began selecting foxes based on their friendliness towards people. They bred the most friendly foxes together and then compared the friendliness of their offspring to the offspring of randomly bred foxes. The results showed that friendlier foxes differed in physiology in addition to behavior, and were better at cooperating and communicating with humans. This is an example of self-domestication, which changes development patterns and has increased fitness via friendliness. Friendliness in this case means skill in cooperating and communication. 

Survival of the Friendliest argues that humans today are the friendliest species of human, which may be why we have lasted so long evolutionarily. However, with the new type of friendliness also comes a new type of aggression. Mother bears are kind and nurturing to their cubs, but also have the most potential for aggression when they feel their cubs are threatened. Similarly in humans, when we feel people who share our identity are threatened, we want to protect those individuals.

Hare and Woods reason that this desire to protect also reduces our ability to cooperate or communicate with those who we feel threaten us or threaten our “group”— whether this be our family, our race or another trait. When our ability to communicate is reduced, we begin to dehumanize those who we feel threaten the people who share our identity. This then becomes a cycle, where people dehumanize those who they believe are dehumanizing them.

In order to stop this cycle, Hare and Woods argue that humans will need to alter their view of who they believe “belongs” to their group to include more people. We need to communicate openly and build a desire to protect other humans, rather than dehumanize them.

Scholars Examine Duke’s History of Unequal Medical Care for Black People

Conversations on and actions toward making American medicine less racist continue to grow. At Duke, that includes looking at our own history as a hospital and medical center serving a diverse community.

In a Sept. 22 virtual conversation, Duke physicians Damon Tweedy M.D., Associate Professor of Psychiatry and Behavioral Sciences, and Jeffrey Baker M.D., Ph.D., Director of the Trent Center for Bioethics, Humanities, and History of Medicine, spoke about the history of Duke’s legacies of race and memory. (Watch the presentation here.)

The career of Dr. Baker, who is a professor of both pediatrics and history, has taken him around the globe, right back to his hometown of Durham –where he said he has found the most interesting story of all.

After becoming Director for the Trent Center in 2016, he was approached with “hunger” by Durham natives to know their hometown’s story. Through oral and archival sources, Dr. Baker has broached Duke hospital’s history with humility in hopes of uncovering and contextualizing the historical roles of race in Duke medicine and Durham.

Dr. Tweedy, author of Black Man in a White Coat, attended Duke for medical school in the 1990s. He was warned that it was a plantation and an institution built on tobacco and slave money.

Though Dr. Baker proposed that in many ways the hospital structure often reflects plantation hierarchies in which there is racialization of who holds what jobs and power, he said Duke’s endowment money actually came from technological progress within tobacco production rather than slavery or plantations directly.

The Duke family’s vision for the hospital was quite different from actual outcomes in practice, Dr. Baker said. The Dukes were considered racial progressives in their time and the endowment they provided to launch the Duke Medical School and Hospital in 1930 was meant to improve health and education in North Carolina and train primary care doctors for the state.

“However,” Dr. Baker said, “there were two realities: Jim Crow and the Great Depression.”

During the era of Jim Crow segregation, Duke’s primary care doctors were all white, and nearly all male. Though the hospital cared for both Black and white patients, they were segregated by race. Black patients had separate wards, and waiting areas for pediatric care were separated racially by days of the week. Waiting areas for adult patients functioned without appointments, but only white people were seen before noon. It’s likely that the care granted to white people in the first half of the day was superior to that of Black people receiving care at 4 pm or told to return the next day, he said.

The Great Depression also generated a diversion from plans in the 1940s. When the Duke Hospital came close to bankruptcy, it chose to open private clinics on the side for revenue – which had an unintended consequence. The clinics brought a lot of money into Duke, Dr. Baker said, but it also reinforced distinctions between those who could pay for treatment and those who couldn’t. Over time, the disparities expanded with shifts towards hospital beds for insured and private patients.

In one terrible example, Maltheus “Sunny” Avery, a North Carolina A & T graduate who got into a car wreck in Burlington, NC in 1950, was diagnosed with an epidermal hematoma — a clot near his brain — and sent to Duke for emergency brain surgery. But he was refused treatment due to inadequate room in the “colored” ward.

Avery was redirected to Lincoln Hospital, Durham’s Black hospital, where he died shortly after admission. Though Dr. Baker said this story quickly faded from white memory, it is something that has retained severe importance in the popular memory of Black Durhamites. This narrative is also often conflated with a similar story about Dr. Charles Drew, the Black inventor of blood banking, who died despite attempts at rescue at a white hospital in Alamance, NC. He is often misremembered as having died from the refusal of care in a racially divided South, even though he was not.

Duke’s first Black medical student, Delano “Dale” Meriwether, arrived the same year the hospital began desegregation, 1963, and he was the first Black M.D. in 1967. Meriwether was the only Black medical student for four years before other brave pioneers joined the school.

Dr. Tweedy reflected on his own medical school experiences at Duke during clinical rotations just a little more than 20 years ago.

“I was asked to help suture a deep gash on a Black patient’s forehead,” he said, “The patient asked if we were experimenting on him since I was still a student.” In the private clinics, he once “couldn’t go anywhere near” a white patent with a minor lesion on their arm, let alone suture that patient.

Dr. Baker said there are two narratives surrounding Duke Hospital’s desegregation. One assumes that desegregation was quick and easy and uneventful, while the other proposes that systems of racial segregation were simply transformed rather than eradicated. The latter narrative better applies to the public and private clinics that had become nearly completely racialized over time, Baker said.

Even though segregation was no longer legal,  Black patients received care from less experienced medical residents in the public clinics, while white patients received care from attending physicians in the nicer, private environments.

Dr. Baker said that Duke has a complicated relationship with the community of Durham. He said the merger of Durham Regional Hospital with Duke Health in the late 1990s tapped into some long-term tensions and distrust between Duke and other medical facilities of Durham.

Dr. Tweedy pointed out that Duke researchers always have trouble recruiting Black patients for clinical studies, despite the fact that Durham County is about half Black and Hispanic. There is some distrust to overcome, but a diverse patient population is essential to creating robust study data that ensures that treatments will work for everyone, he said.

Medical professionals “need more than just science,” Baker concluded. He said that being trained as scientists often inclines doctors to think that they are above the larger contexts and histories they exist within, and that they can somehow remain objective.

“We have come out of specific stories and backgrounds,” Dr. Baker said. “[When we treat patients], we have to think about what story we are walking into.”

“We all carry our bags of ‘stuff'” that complicate patient prognosis and care, Dr. Tweedy concurred.

As Ann Brown (M.D., M.H.S), Vice Dean for Faculty, stated at the beginning of the conversation, “In order to move forward, we must understand where we come from.”

This is true of our nation as a whole, and Duke is certainly no exception.

Dealing With Lead for Life

Though lead has been widely eliminated from use in products due to proven health risks, the lifelong consequences of childhood lead exposure for children born in the era of lead use in gasoline are still unknown.

Aaron Reuben, fifth-year Ph.D. candidate in clinical psychology at Duke, spoke about the long-term implications of childhood lead exposure Friday, September 18th through the Nicholas School’s Environmental Health and Toxicology Seminar series. He conducts research as a member of the Moffitt and Caspi Lab, studying genes, environment, health, and behavior.

Aaron Reuben

Reuben started with a brief history of lead exposure. After the United States’ initial use of lead in gasoline in 1923, the practice became widespread with the U.S. Public Health Services approval for expansion. Five decades later, in the mid-1970s, the Environmental Protection Agency issued the first restrictions on lead use in gasoline products. Simultaneously, surveillance of population-level blood-lead levels indicated cause for concern. Though lead was phased of out of gas completely by 1995, the peak led exposures in the 70s were on average three to four times higher than current levels that demand clinical attention. Despite lead regulations, the impacts of exposure did not miraculously cease as well.

Lead use in gasoline quickly increased after its initial introduction.

The research Reuben covered in his talk centers on the Dunedin Study. This study of 1,037 people born between April 1972 and March 1973 in Dunedin, New Zealand is an ongoing longitudinal research project comprised of over 30 years of data. The cohort of participants provide a unique chance for research in which social and economic factors do not have to be detangled from findings as they represent the full range of socioeconomic statuses in their city.

Reuben’s first question was about the impact of lead exposure on psychiatric and personality differences in adulthood. Study members were asked about symptoms such as substance dependence, depression, fears and phobias, or mania. These reports were transformed into a continuous measure of general psychopathology, which indicated that children with high lead levels experienced more psychiatric problems across adulthood. Though the developmental differences were modest, the associations between lead and psychopathological issues are of a similar magnitude to other known risk factors like childhood maltreatment and family history of mental illness. Yet, unlike the latter two risk factors, Reuben said, “Lead exposure is not preordained – it’s modifiable.”

The research team also measured participant personality using the Big Five Inventory and found that individuals with high-blood level levels as children exhibited more difficult personality styles as adults. The biggest difference between groups with high and low childhood blood-lead level was the trait of conscientiousness, which has impacts on goal obtainment within one’s education and occupation, as well as overall satisfaction with relationships.

Findings from the Big Five Inventory of Dunedin participants.

The next question of the presentation centered on differences in adulthood cognitive ability. At midlife, defined as age 38 for this question, children with higher blood-lead levels had lower cognitive ability, experiencing a deficit of two IQ points per five microgram per deciliter increase of blood-lead level. Once again, though these findings were relatively modest, the loss of IQ points was accompanied by downward social mobility compared to participants’ parents. Further, when evaluations that took place at age 45 were included in the data, researchers saw even larger declines in IQ points between exposure-level groups, which Reuben predicts may even represent a trend of acceleration. He believes that as the study continues with the participants, they will find rapid decline around age 65, with higher levels of dementia symptoms among participants compared to same-aged peers.

The last question evaluated the structural integrity of the brain at midlife. The team found that children with higher lead exposure had lower gray-matter integrity, lower white-matter integrity, and older estimated brain age at age 45. Estimated brain age was predicted by an algorithm based on MRI scans, as brains look physically different as they age and gray- and white-matter integrity refers to the conditions of physical structures in the brain. These findings suggest that childhood led exposure may result in an overall lowered brain integrity at midlife, as well as accelerated brain aging.

Reuben’s take-away findings from his presentation.

Reuben’s work is important for understanding how childhood exposure to this neurotoxin has the ability to influence continued development, behavior, emotion, and life outcomes decades later. It is crucial to evaluate long-term ramifications of childhood lead exposure – a phenomena experience by hundreds of millions of people across the globe during the era of lead in gasoline who are likely unknowingly dealing with impacts now.

We Are Not All Living The COVID Moment Equally

We are all living within the Covid moment, but we are not living within the Covid moment equally. The pandemic has exposed a recurrent rift in the United States’ healthcare system: Black Americans and other people of color (POC) are both disproportionately impacted by health issues and disproportionately lack access to care.

In a recent study on North Carolina conditions, Duke researchers found that the “odds of testing positive for [Covid] were higher for both Black and Hispanic individuals as well as within neighborhoods with a higher proportion of Black or Hispanic residents – confirming that Black and Hispanic communities are disproportionately affected.”

In a Coronavirus Conversation sponsored last week by the Science & Society Initiative, Thomas Williams J.D. discussed this and related issues with Duke scholars Keisha L. Bentley-Edwards, Ph.D. of medicine and Jay A. Pearson, M.P.H., Ph.D of public policy.

Williams opened the panel by emphasizing the relevance of this moment: Current Covid impacts are directly informed by historical inequities and intricately span into the future. This is but one system of plaguing racism.

To speak about the intimate intersection of race and healthcare in America, Pearson offered grounding insight to systemic and structural racism. The United States is a country filled with patterns that produce and reproduce systematic advantages for those who are white while simultaneously disadvantaging people of color, most often Black and indigenous populations. Racism in America greatly transcends personal acts of racialized discrimination and harassment, he said. Racism in America is multiplex, foundational, and rooted within our society’s core.

“The U.S. national identity is tied to structural racism. …This is who we are, this is who we’ve been since the beginning of this country,” Pearson said, “The racialized inequities of Covid are simply the latest [manifestations]. We shouldn’t be surprised.”

A recently circulating figure states that 96% of people with severe outcomes or death from Covid had comorbidities, the presence of health conditions in addition to Covid. But Bentley-Edwards cautioned against misuse of this claim: “Many of these people would be alive if not for Covid.”

Though many who have died from the virus had underlying conditions, it is ultimately the virus that killed them. Communities of color often have disproportionate prevalence of underlying conditions, making them more susceptible to complications from Covid. But even when the prevalence of underlying conditions is the same among white and non-white populations, people of color are more likely to be more negatively affected by them.

For example, cardiovascular disease is similarly distributed between white and Black people, yet Black people are more likely to die of it, and at a younger age, compared to white people. Similarly, Black and other POC populations who contract Covid are more likely to die despite similar rates of contracting the virus in certain regions of the country.

Dr. Bentley-Edwards speaking during Friday’s virtual Coronavirus Conversation

Pearson and Bentley-Edwards also offered their insights on who is seen as essential and who is seen as dispensable in the United States.

Those who have been on the front lines with the most exposure and risks have been laborers who are most often under-valued Black and Brown peoples, Bentley-Edwards said. Though Covid terminology has come to dub them essential, it is undeniable that our society continues to see these types of workers as dispensable or replacable, and thus does not protect the people responsible for protecting us. Because many people of color live in multi-generational households as a culturally protective factor, increased chance of contracting Covid has led to uncertainties on the safety of returning home to young and elderly family members, she said. Further, the disproportionate unemployment rate of 13% for Black Americans compared to the 8.4% national rate is a staggering one. Since insurance is tied to employment, Black and Brown communities often avoid treatments due to the financial burden of unaffordable and inaccessible care.

Within the pandemic, we have seen the ever-present epidemiological impacts of police brutality and murder in the U.S with fresh eyes, the panelists said. In many ways, Black peoples’ experiences with healthcare mirrors that of their experiences with police – likely because both systems are anchored by an unjust nucleus.

“[Covid and police brutality] are slightly different manifestations of the same phenomenon,” Pearson said. We are able to easily identify the murders of individuals such as Breonna Taylor, George Floyd, and Ahmaud Arbery as stolen lives due to racist actions, however the slow burn of a racist health care system is less easily conceptualized or reconciled with, he said. Either way, the cause is one and the same.

Racism within systems that are meant to protect have generated a deep mistrust from Black and Brown people. Williams brought up the issue of a potential Covid vaccination amongst communities of color. “You have to know the history and why they would hesitate,” Bentley-Edwards said, bringing up the Tuskegee experiments and the work of J. Marion Sims. These accounts offer grim revelation of a heinous, racist history of exploiting vulnerable people for scientific and medical explorations.

Bentley-Edwards said that governments and healthcare institutions must address the rightful apprehensions of Black and Brown people in order to decrease vaccine hesitancy and serve at-risk communities. “What are they going to do differently?”

Williams also proposed the notion of data collection as a source of bias: In what ways are the data informatics that are collected reflections of an inequitable system? Bentley-Edwards and Pearson both suggest that to understand the current moment, as well as the healthcare system more largely, there needs to be collection and analysis of racial data. Additionally, there simply needs to be measurements for indicators beyond conventional ones which do not properly account for impacts on communities of color.

The push for new and different kind of data is supported by a growing evidence for the manifestations of inequality within biological bodies. For example, Pearson spoke about his own research on telomeres, a protective structure on the ends of chromosomes that protect DNA from degradation. Telomeres are telling both of stress and aging. Pearson’s work found that the average Black American woman is six to seven biological years older than a white American woman of the same age by evaluating telomere lengths, controlling for income, education, and other important socioeconomic factors. This indicates physiological affects linked to the stresses and disproportionalities of race down to the cellular level. Through genetics, mental health, and other physical degradations, the impacts of racism and racist healthcare quite literally last a lifetime and are even intergenerational.

Pearson closed the panel by urging attendees to take action where they find themselves. Though the need for animated policy which reflects recent discussions and protests is dire, the local spaces we find ourselves in need to be reshaped as well – including our universities.

In this moment, our responsibilities to one another have become more obvious than ever before. We must become more adept in thinking about and taking action for the communities in which we live and are connected to, whether they are comprised of people who look like us or not.
