Genetics could explain why some people get severe COVID-19

July 21, 2021.  One of the greatest mysteries of the COVID-19 pandemic is why some people fall severely ill while others suffer nary a sniffle. Now, after compiling data from around the world, researchers have determined that the answer seems to lie, in part, in genetics.

"Teams of scientists from around the world shared data as quickly as it was generated, and this data was analyzed almost as quickly as it was shared," said Manuel Rivas, DPhil, assistant professor of biomedical data scientist and PHS faculty fellow who helped lead Stanford's contribution to the analysis. "That's transformative for our understanding of the genetics behind COVID-19 infection. This type of rapid data sharing and analysis hasn't been the model for studying other viruses, but it really should be."


A majority of Americans think children will be financially worse off than their parents, survey finds

July 21, 2021.  The coronavirus pandemic has made parents pessimistic about their children’s future, according to a survey by Pew Research.

More than two-thirds (68%) of U.S. respondents said they think today’s children will be financially worse off as adults than their parents, up from 60% in 2019. Only 32% think children will be better off.

2016 study co-authored by Stanford sociologist and PHS faculty fellow David Grusky, found that only half of those born in 1984 were earning more than their parents, compared to 92% of those born in 1940.

The main reason for the decline is that income inequality dramatically increased over this time period, Grusky explained.

“If the benefits of economic growth had instead been broadly shared, then a large swath of children would be doing better than their parents,” he said.

In order to reverse the trend, that economic success has to reach everyone, he noted.

“It would solve the absolute mobility problem … and a great many other problems facing our country.”


Virus or Bacterium? Rapid Test Pinpoints Infection’s Cause

July 20, 2021.  Runny nose, cough, fever: patients show up in clinics every day with these classic symptoms of respiratory infection. But is the culprit a bacterium, which can be attacked with antibiotics, or a virus, which is harder to target with medication? Often doctors cannot be certain. But researchers say they are closing in on an accurate test that can make the call quickly, right in a physician’s office.

Technology to examine genes’ response to pathogens in a rapid and integrated way was just recently developed, says Stanford University Purvesh Khatri, PhD, associate professor of biomedical informatics and of biomedical data science, and the Center for Population Health Science, faculty fellow. Purvesh Khatri, who was not involved in the study. Amplifying RNA through PCR-based methods, a key analytic step, can now be done in 15 to 20 minutes. Khatri co-founded Inflammatix, a company set to soon release its own rapid test “to tell whether there is an infection and which [pathogen] is likely causing it and also give information about severity.”


Study shows why second dose of COVID-19 vaccine shouldn’t be skipped

July 17, 2021.  The second dose of a COVID-19 vaccine induces a powerful boost to a part of the immune system that provides broad antiviral protection, according to a study led by investigators at the Stanford University School of Medicine.

“Despite their outstanding efficacy, little is known about how exactly RNA vaccines work,” said Bali Pulendran, PhD, professor of pathology and of microbiology and immunology. “So we probed the immune response induced by one of them in exquisite detail.”

He shares senior authorship of the study with Kari Nadeau, MD, PhD, the Naddisy Foundation Professor of Pediatric Food, Allergy, Immunology, and Asthma and professor of pediatrics, and Purvesh Khatri, PhD, associate professor of biomedical informatics and of biomedical data science, and the Center for Population Health Science, faculty fellow. The study’s lead authors are Prabhu Arunachalam, PhD, a senior research scientist in Pulendran’s lab; medical student Madeleine Scott, PhD, a former graduate student in Khatri’s lab; and Thomas Hagan, PhD, a former postdoctoral scholar in Pulendran’s Stanford lab and now an assistant professor at the Yerkes National Primate Research Center in Atlanta.

The center is led by faculty directors at Stanford University, the University of Southern California, the University of California at Davis, the University of California at Los Angeles, and the University of California at Berkeley.


Stanford researchers offer practical tips to mitigate harm from wildfire smoke

July 7, 2021.  Warnings of another severe wildfire season abound, as do efforts to reduce the risk of ignition. Yet few are taking precautions against the smoke. Stanford experts advise on contending with hazardous air quality.

The health effects of wildfire smoke are well-documented in research by Kari Nadeau, director of Stanford’s Sean N. Parker Center for Allergy & Asthma Research, and Mary Prunicki, the center’s director of air pollution and health research.

Economist Marshall Burke, associate professor of Earth system science in the School of Earth, Energy & Environmental Sciences, and faculty fellow, Center for Population Health Sciences, has studied the toxicity of wildfire smoke from an environmental justice perspective. Leakier structures in less economically advantaged communities allow more particulate matter to travel indoors, Burke explained during a May presentation at a Stanford symposium on energy and water in the West.


Racial, ethnic disparities in COVID-19 vaccination coverage

July 1, 2021. New joint research by Stanford Health Policy and the Kaiser Family Foundation indicates that at the pace of vaccination, 65% of people ages 12 and older in the United States would be at least partially vaccinated by July 4 -- but for Hispanic and Black people, rates are lower.
The researchers wrote in their study, which was published by the foundation, that vaccination rates among Black and Hispanic people have lagged behind those of white people, largely a result of access and logistical barriers, as well as concerns about safety and potential side effects.
Marissa Reitsma, a graduate student, PHS and lead author on the study, noted vaccine data by race and ethnicity are inconsistently reported across states, making it hard to monitor vaccine equity. 


Why eliminating the SAT would not help Black or Hispanic students

June 29, 2021. But if we abolish the SAT, we will lose our best measure of the academic skills of high school students, while doing exactly nothing to improve the skills of Black and Hispanic students. That problem will remain whether we measure it or not.
A study by Benjamin Domingue, assistant professor in the Graduate School of Medicine and faculty fellow at the Center for Population Health Sciences, Stanford University, and Derek Briggs of the University of Colorado estimated that students who receive coaching increase their math scores by only 11 to 15 points and their verbal scores by only 6 to 9 points, compared with otherwise similar students who receive no coaching.

The study’s lead author is Bibek Paudel, PhD, research fellow at the Sean N. Parker Center and the Stanford Woods Institute for the Environment and postdoctoral research fellow with the Center for Population Health Sciences.


San Diego Group Repurposes Sleep Apnea Machines to Help India Fight COVID-19

June 11, 2021.   India has been devastated by a catastrophic second wave of the virus, overwhelming hospitals and already suffering from a dire lack of oxygen and ventilators while other parts of the world are transitioning from COVID-19 to recovery mode I’m out.

“You can’t build a medical ventilator in your garage, but you can do this in your garage,” said Dr. Sakya Tripathy, a biomedical engineer, while holding a donated CPAP machine. “It’s in most homes, and when assembled with tubes and masks, it’s a very good and cheap ventilator. It’s a very interesting and innovative solution to very complex problems.”

 Manu Prakash, PhD, associate professor of bioengineering of Stanford University, a roommate at Tripathy University, said at the start of the pandemic that CPAP and BiPAP sleep apnea devices would be reused for non-invasive ventilators at his Bay Area Institute. Developed a cost-effective idea.


Maternal care and race: ‘Birth equity is where a whole life starts’

June 8, 2021.   The United States has the highest maternal death rate of any wealthy nation, and the proportion of women who experience severe, nonfatal childbirth complications has nearly tripled since 1993.

"We all deserve to be able to expect equal treatment when we receive medical care," said Stanford epidemiologist Stephanie Leonard, PhD, whose research -- featured in the article "Childbirth's unequal burden" -- has helped illuminate how pregnant and birthing women are not equally treated.


Stanford explainer: Social cost of carbon

June 8, 2021.   Carbon emissions not only are causing widespread and potentially irreversible damage to the environment but also may have significant impacts on the economy. Here, Stanford University economists Marshall Burke (faculty fellow at the Stanford Center for Population Health Sciences) and Lawrence Goulder explain one tool for understanding those impacts: the social cost of carbon. Burke and Goulder describe what the social cost of carbon is, how it is calculated and used in policymaking, and how it relates to environmental justice.


Theranos is history, but big blood testing breakthroughs are coming post-Covid

June 7, 2021.   Medical researchers say within a few years major breakthroughs in blood testing technology that use immune system response and genetic analysis to identify disease quickly and cost-effectively will be on the market.

While neither the FDA nor any European regulators have approved these kinds of gene-based pathogen detection systems, Purvesh Khatri, an associate professor at the Stanford Institute for Immunity, Transplantation and Infection and Department of Medicine, and faculty fellow at the Stanford Center for Population Health Sciences, Khatri, who is helping launch a related commercial venture, says they’re coming soon. “In the next year or two, there will be several that will be available on the market.”


Stanford’s Dr. Latha Palaniappan Helps Measure Impact

June 4, 2021.   Dr. Palaniappan is a diabetes expert and researcher at Stanford Medical Center, and the founder of its Center for Asian Health Research & Education (CARE), who is focused on the study of diverse populations, chronic disease, and prevention. Given the alignment of her research and Arogya’s mission, she is spending her sabbatical this year with Arogya World.

India has the greatest number of people with diabetes. Arogya’s programs, including its Healthy Workplaces, mDiabetes, MyThali, and Healthy Schools, all focus on helping people make healthy lifestyle changes to prevent diabetes. Dr. Palaniappan and her students will study the impact of these programs including how digitization can affect change. The use of contactless mobile technology, such as text messaging has been shown to be successful in affecting self-reported behavioral changes. And, as Dr. Palaniappan says “digitization makes chronic disease prevention efforts more scalable.”


Toolmakers aim to untangle fundamental challenges in neuroscience

June 3, 2021.   But two groups of Stanford researchers are tackling these long-standing problems head on. As part of the Wu Tsai Neurosciences Institute’s Big Ideas in Neuroscience program, they are forging new technologies and connections between disciplines that have the potential to transform the field:

The Neuro-Omics Initiative is bringing to bear new technologies to bridge long-standing gaps in understanding between molecular and systems-level descriptions of the brain, while the Stanford Brain Organogenesis Program is developing new laboratory models of human brain circuits to allow the field to study the human brain’s unique development — and how its complex circuits go awry in neurological and psychiatric disease.

Joining the effort are a multi-disciplinary team of collaborators, including machine learning expert and faculty fellow with the Stanford Center for Population Health SciencesJure Leskovec, PhD, evolutionary and organismal biologist Lauren O'Connell, PhD, and bioengineer and developmental biologist Bo Wang, PhD.


Do College Application Essays Favor the Wealthy?

June 3, 2021.   Everyone has heard that the SAT and ACT correlate with family wealth. Wealthier students generally attend high schools that are focused on the college application process, and many offer special programs for students to stretch their skills. Wealthier students can afford to hire SAT or ACT tutors and to take the tests as many times as possible.  

So what are colleges to do?

Inside Higher Ed posed that question to the authors of the paper, AJ Alvero, Sonia Giebel, Anthony Lising Antonio, Mitchell L. Stevens, Benjamin W. Domingue of Stanford, assistant professor, Graduate School of Education, and faculty fellow with the Stanford Center for Population Health Sciences, and Ben Gebre-Medhin of Mount Holyoke College. They provided a joint answer:

The environmental case for remote working

June 3, 2021.   Anyone searching for a silver lining to the pandemic should look to the clear, blue skies above them. A reduction in pollution worldwide has been an unintended benefit of the lockdowns and stay-in-place orders imposed to control the spread of COVID-19.

The fall in pollution during China country’s lockdown in January and February “likely saved 20 times more lives in China than have currently been lost due to infection with the virus in that country”, calculates Marshall Burke of Stanford University’s Department of Earth System Science and faculty fellow at the Stanford Center for Population Health Sciences, as reported in Forbes in March. He adds: “The fact that disruption of this magnitude could actually lead to some large (partial) benefits suggests that our normal way of doing things might need disrupting.”


Countering decades of racism in medicine

June 3, 2021.   Race and health in the United States are traditionally intertwined and, often, it's at the expense of people of color. Recent public health data makes that abundantly clear: People in Black and Latino communities are more likely to be exposed to, contract and die from COVID-19. African Americans have the highest mortality rate for all cancers when compared with any other racial or ethnic group. When compared with white adolescents, Indigenous American and Alaska Native adolescents are 30% more likely to be obese.

Food as medicineLisa Goldman Rosas, PhD, assistant professor of epidemiology and population health and of medicine and associate faculty director, community engagement, PHS, is testing the power of leafy greens in a study designed to determine whether healthy foods can mitigate chronic disease risk. Goldman Rosas and others are collaborating with local sustainable farmers to connect people at high risk for chronic disease with weekly boxes of vegetables and recipes to prepare them.


After Decades On The Rise, U.S. Life Expectancy Has Stalled

May 24, 2021.   Americans live shorter lives than people in other high-income countries. Many experts believe the culprit is socioeconomic inequality.

Ample evidence suggests that low-income populations face a health disadvantage throughout life. They are more prone to smoking. They are less physically active, often living in landscapes unsuited to exercise. Those same environments may lack nutritious food, green space, clean air and other essential components of wellbeing. Many of the direct causes of premature death are individual choices, but research finds them associated with economic choices made, ultimately, by governments. “This is driven by pretty intentional decisions over time, in terms of our federal policies and state policies,” says David Rehkopf, a social epidemiologist and co-director at the Center for Population Health Sciences at Stanford University. 


COVID aid to India: Stanford scientists rally to combat crisis

May 20, 2021.   Nidhi Rohatgi, MD, clinical associate professor of medicine and many of her colleagues -- including Aruna Subramanian, MD, clinical professor of medicine; Manu Prakash, PhD, associate professor of bioengineering; and Sonoo Thadaney, executive director of presence and program of bedside medicine -- are leading an effort from thousands of miles away to provide assistance and combat harmful misinformation circulating in India about COVID-19 and how to treat it.

With hugs and haircuts, U.S. epidemiologists start returning (carefully!) to everyday life

May 12, 2021.  In a new informal survey this month by The New York Times, 723 epidemiologists in the United States responded to questions about their life now and how they are navigating this in-between phase of the pandemic, when vaccines have become widespread and cases are declining nationally, but herd immunity is not assured and Covid-19 remains a threat.
“I would be more comfortable taking risks if I did not have young, unvaccinated children whom I want to keep healthy and who need to be in day care for me to keep working,” said Stephanie Leonard, an epidemiologist at Stanford.


Silent calamity: The health impacts of wildfire smoke

May 12, 2021. Marshall Burke, an associate professor of Earth system science at Stanford is lead author of a 2021 paper in the Proceedings of the National Academy of Sciences (PNAS) on the evolving, multipronged threat posed by increasing U.S. wildfires.

In an October 2020 policy brief, Burke and two Stanford colleagues noted that wildfire smoke likely is responsible for 5,000 to 15,000 U.S. deaths in a typical year, and that especially smoky years like 2018 or 2020 will have a much higher death toll.


Stanford researchers map how people in cities get a health boost from nature

May 11, 2021.  Your local city park may be improving your health, according to a new paper led by Stanford University researchers. The research, published in Proceedings of the National Academy of Sciences, lays out how access to nature increases people's physical activity - and therefore overall health - in cities. Lack of physical activity in the U.S. results in $117 billion a year in related health care costs and leads to 3.2 million deaths globally every year.

April 30, 2021.  Madhukar Pai is a professor of epidemiology and global health at McGill University. Manu Prakash is an associate professor of bioengineering at Stanford University’s Center for Innovation in Global Health.

The covid-19 crisis in India is a massive setback for the entire world. The scale of the nation’s surge is a warning not only for its neighboring countries, which are also experiencing sharp increases in cases, but also for countries around the globe. If we do not heed this warning and work on vaccine equity, we risk a forever pandemic with long-term cycles of lockdowns, economic damage and constant fear.

Waiting for data: Barriers to executing data use agreements

Many academic researchers who use preexisting data to conduct research describe a common experience: waiting for university officials to finalize and sign contracts necessary to transfer the data. These data use agreements (DUAs) detail the terms under which data will be disclosed, transferred, stored, and used, specifying rights and obligations for both the data supplier and the recipient (1). Faculty members often struggle to understand why DUAs for transfers of seemingly low-risk data take so long to conclude. To understand reasons for delays and explore what might be done to streamline the process, we interviewed a sample of university officials responsible for negotiating DUAs.

How many steps should you take a day?

Humans are moving less than ever. Humans, once in constant motion as hunters and gatherers, are moving less than ever. At first, this trend seemed like progress: Transferring our heavy and dangerous work to animals, then machines, enabled more people to live longer. As recently as the 1950s, doctors considered exercise dangerous for people over age 40; for heart disease, which was then killing a record number of Americans, they prescribed bed rest.

Stillbirth linked to more childbirth complications for mom, Stanford study finds

Life-threatening delivery complications are more than four times as common during and after a stillbirth than a live birth, and some of these complications are more than 10 times as likely with stillbirths, a new Stanford study has found.

The research, which was published in Obstetrics & Gynecology, is the first large, population-based study to ask whether stillbirth puts women at greater risk than live birth. The researchers used data from more than 6 million California births between 1999 and 2011.

"We really need to start thinking more about the quality of maternity care for women whose pregnancies don't result in a live birth," said Elizabeth Wall-Wieler, PhD, the lead author of the new study. Maternal complications in stillbirth have seldom been studied because stillbirths themselves are rare, affecting six of every 1,000 births, she said.”


U.S. 'gag rule' linked to 40% jump in abortions in parts of Africa

New research finds that U.S. foreign policy that cuts money to nongovernmental organizations performing or promoting abortions abroad has actually led to an increase in abortions, because loss of funding cuts availability of contraceptives, with unwanted pregnancies the result. The study, which was led by Eran Bendavid and Grant Miller – both associate professors of medicine – and doctoral candidate Nina Brooks, is highlighted here.

The common denominator to improving health in developing countries: Democracy

Most studies that look at whether democracy improves global health rely on measurements of life expectancy at birth and infant mortality rates. Yet those measures disproportionately reflect progress on infectious diseases — such as malaria, diarrheal illnesses and pneumonia — which relies heavily on foreign aid.

A new study led by Stanford Health Policy's Tara Templin and the Council on Foreign Relations suggests that a better way to measure the role of democracy in public health is to examine the causes of adult mortality, such as noncommunicable diseases, HIV, cardiovascular disease and transportation injuries. Little international assistance targets these noncommunicable diseases.

Immune cell turned biomarker: Prediciting severity of lung scarring

By crunching a massive amount of patient data, scientists have found a marker that can predict survival of a life-threatening lung disease. The disease, called idiopathic pulmonary fibrosis, develops without warning and leads to irreversible scarring in the lungs, ultimately cementing the stretchy tissue over time until it can no longer expand.
Now Purvesh Khatri, PhD, and Nigam Shah, PhD, associate professors of medicine and of biomedical data science, have found a biomarker that flags which patients with pulmonary fibrosis are most at risk for imminent lung failure.  A paper detailing the research was published in The Lancet Respiratory Medicine. Khatri and Shah are the senior authors, and graduate student Madeleine Scott is the first author.
