Fatal police violence nearby increases risk of preterm birth

Higher incidence of preterm births correlates with police violence in Black communities, UCSF study finds

2021-03-11
(Press-News.org) Black women have 80% higher risk of preterm birth between 32 and 33 weeks of pregnancy if a Black person who lives in their neighborhood is killed by police during the pregnancy, according to a study by researchers at UC San Francisco and UC Berkeley.

The study by scientists at the UCSF California Preterm Birth Initiative (PTBI-CA) and UC Berkeley School of Public Health, studied the records of 3.8 million pregnant women to assess whether fatal police violence occurring in their neighborhood during pregnancy was associated with extremely early, early, moderate or late preterm delivery.

"Our findings suggest that deaths due to police violence, which already differentially affect Black and Brown communities, adversely affect the health of mothers and babies during pregnancy," said first author Dana Goin, PhD, post-doctoral scholar in the UCSF Department of Obstetrics, Gynecology, and Reproductive Sciences. "In addition, we observed the strongest associations with preterm birth when the victim of the lethal violence and the mother/birth parent were both Black."

The researchers analyzed California Department of Public Health (CDPH) birth records from 2007 to 2015, using the birth parents' addresses to determine the parent's census tract of residence. They examined two different sources of police violence data, specifically CDPH death records that capture deaths due to "legal intervention" and records from the Fatal Encounters database that collects media-based accounts of police violence. They matched the police violence measures to the time range of the pregnancies, using as their control group residents of the same census tract who did not experience police violence during their pregnancy. The study published March 10, 2021, in Paediatric and Perinatal Epidemiology.

According to the analysis, neighborhoods where at least one incident of fatal police violence occurred tended to be where birth parents were Black or Latinx, had less than high school education and had public insurance, compared to all the births in California.

The World Health Organization lists preterm birth as a baby born at 37 weeks or earlier, compared to a 40-week "full-term" pregnancy, and considers birth at 32 to 33 weeks to be "moderate preterm. The Centers for Disease Control and Prevention (CDC) lists the rate of preterm births among Black women as 50% higher than the rate of preterm births among white or Latina women.

The researchers also discovered that the associations of fatal police violence with preterm birth were stronger among female infants. Since male fetuses are more sensitive to stress during pregnancy, it is plausible that male fetuses exposed to police violence may have been more likely than female fetuses to be miscarried earlier in the pregnancy, said Goin, who intends to explore this possibility further in a subsequent study.

"Our research provides evidence that policing practices that differentially harm Black people in California can also contribute to their disproportionate risk for preterm delivery," she said. "This work contributes to the evidence that additional forms of stress and hardship experienced from racism and institutional violence significantly affect their health and the health of the next generation."

With masks on, three feet is just as safe as six feet apart in Massachusetts schools

2021-03-11
BOSTON - As COVID-19 infection rates continue to fall, Massachusetts officials are signaling it's almost time to end remote learning and send all school-aged children back to the classroom. While emerging data suggest young children and schools have not been primary drivers of the COVID-19 pandemic, evidence to guide best practices to prevent the spread of the virus in the school setting has been limited and, as a result, national and international recommendations are inconsistent. A study led by Beth Israel Deaconess Medical Center (BIDMC) physician-researchers provides new, much-needed data about the optimal physical ...

Climate change influences river flow

2021-03-11
Climate change is affecting the water balance of our planet: depending on the region and the time of year, this can influence the amount of water in rivers potentially resulting in more flooding or drought. River flow is an important indicator of water resources available to humans and the environment. The amount of available water also depends on further factors, such as direct interventions in the water cycle or land use change: if, for example, water is diverted for irrigation or regulated via reservoirs, or forests are cleared and monocultures grown in their place, this can have an impact on river flow. However, how river flow ...

Polarization: From better sunglasses to a better way of looking at asteroid surfaces

Polarization: From better sunglasses to a better way of looking at asteroid surfaces
2021-03-11
Using the same principles that make polarized sunglasses possible, a team of researchers at the Arecibo Observatory in Puerto Rico have developed a technique that will help better defend against asteroids on a collision course with Earth. A new study recently published in The Planetary Science Journal found a better way to interpret radar signals bounced off asteroids' surfaces. The data can better tell us if an asteroid is porous, fluffy or rocky, which matters because there are hundreds of near-Earth asteroids that could potentially hit the planet. "Learning more about the physical properties of asteroids is crucial in Planetary Defense," says Dylan Hickson the lead author and a research scientist at the Arecibo Observatory in Puerto Rico. "A porous, fluffy asteroid does ...

Hubble sees new atmosphere forming on a rocky exoplanet

Hubble sees new atmosphere forming on a rocky exoplanet
2021-03-11
The planet GJ 1132 b appears to have begun life as a gaseous world with a thick blanket of atmosphere. Starting out at several times the radius of Earth, this so-called "sub-Neptune" quickly lost its primordial hydrogen and helium atmosphere, which was stripped away by the intense radiation from its hot, young star. In a short period of time, it was reduced to a bare core about the size of Earth. To the surprise of astronomers, new observations from Hubble [1] have uncovered a secondary atmosphere that has replaced the planet's first atmosphere. It is rich in hydrogen, hydrogen cyanide, methane and ammonia, and also has a hydrocarbon haze. Astronomers theorise that hydrogen from the original atmosphere was absorbed into the planet's molten magma mantle and is now being slowly released ...

New insight into how cancer spreads

New insight into how cancer spreads
2021-03-11
Breast cancer is harmful enough on its own, but when cancer cells start to metastasize -- or spread into the body from their original location -- the disease becomes even more fatal and difficult to treat. Thanks to new research published in Oncogene from the lab of University of Colorado Cancer Center associate director of basic research Heide Ford, PhD, in collaboration with Michael Lewis, PhD, from Baylor College of Medicine, doctors may soon have a better understanding of one mechanism by which metastasis happens, and of potential ways to slow it down. "Metastasis is a huge problem nobody's tackled very well," says Ford, who ...

Laser-driven experiments provide insights into the formation of the universe

2021-03-11
The universe is filled with magnetic fields. Understanding how magnetic fields are generated and amplified in plasmas is essential to studying how large structures in the universe were formed and how energy is divided throughout the cosmos. An international collaboration, co-led by researchers at the University of Rochester, the University of Oxford, and the University of Chicago, conducted experiments that captured for the first time in a laboratory setting the time history of the growth of magnetic fields by the turbulent dynamo, a physical mechanism thought to be responsible for generating ...

Simultaneous multicontrast OR-PAM from single laser source

Simultaneous multicontrast OR-PAM from single laser source
2021-03-11
Optical-resolution photoacoustic microscopy (OR-PAM), a new hybrid imaging technique, allows us to listen to the sound of light and see the color of biological tissue itself. It can be used for live, multicontrast functional imaging, but the limited wavelength choice of most commercial lasers and the limitations of the existing scanning methods have meant that OR-PAM can obtain only one or two different types of contrast in a single scan. These limitations have made multicontrast functional imaging time-consuming, and it's been difficult to capture the ...

'Hunker down' stress genes boosted in women who live in violent neighborhoods

Hunker down stress genes boosted in women who live in violent neighborhoods
2021-03-11
CHAMPAIGN, Ill. -- The chronic stress of living in neighborhoods with high rates of violence and poverty alters gene activity in immune cells, according to a new study of low-income single Black mothers on the South Side of Chicago. The changes in stress-related gene expression reflect the body's "hunker down" response to long-term threat, a physiological strategy for lying low and considering new actions rather than launching an immediate "fight-or-flight" response. This has implications for health outcomes in communities of color and other marginalized populations, said researchers at the University of Illinois Urbana-Champaign and collaborators at the University of Kentucky and UCLA. The researchers published the study in the journal Psychoneuroendocrinology. "The ...

Birds learn to avoid flashy, hard-to-catch butterflies and their lookalikes

Birds learn to avoid flashy, hard-to-catch butterflies and their lookalikes
2021-03-11
GAINESVILLE, Fla. --- The showy colors of some butterflies could advertise their speed and nimbleness, much like a coat of bright yellow paint on a sports car. A new study shows birds can learn to recognize these visual cues, avoiding not only butterflies they've failed to nab in the past but similar-looking species as well. The research provides some of the strongest evidence to date for the idea of evasive mimicry, a strategy in which animals protect themselves from predators by matching the colors or patterns of agile relatives. First proposed more than 60 years ago, the hypothesis has been a challenge to test. But in an experimental setting, ...
