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.

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.
Bibek Paudel, postdoctoral researcher at Stanford School of Medicine is one of the authors on this paper.

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.

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

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.
