Allocating COVID-19 vaccines based on health and socioeconomics could reduce mortality
Study suggests spatial relationship between COVID-19 mortality and population-level health factors
2021-07-13
(Press-News.org) COVID-19 vaccination strategies in the United States are informed by individual characteristics such as age and occupation. A study published in the open access journal PLOS Medicine by Sasikiran Kandula and Jeffrey Shaman of Columbia University, New York, United States suggests that including socioeconomic indicators as prioritization criteria for vaccination may help minimize severe outcomes, particularly deaths.
Efforts to reduce COVID-19 mortality rates in the US have focused on prioritizing vaccination initially for those at a higher risk of severe outcomes. The effectiveness of population-level health and socioeconomic indicators to determine risk of COVID-19 mortality is understudied. To test the hypothesis that health and socioeconomic indicators can accurately model risk of COVID-19 mortality, the researchers extracted county-level estimates of 14 indicators associated with COVID-19 mortality from public data sources. They then modeled the proportion of county-level COVID-19 mortality explained by identified health and socioeconomic indicators, and assessed the estimated effect of each predictor.
The authors found evidence for a spatial relationship between COVID-19 mortality and 9 health and socioeconomic indicators. The prevalence of chronic kidney disease and the proportion of the population resident in nursing homes had the largest individual effect on COVID-19 mortality. Although the research suggests a correlation between health and socioeconomic indicators and COVID-19 mortality, the study was limited by lags in reporting COVID-19 cases and deaths, and therefore these may have been underestimated.
According to the authors, "Our findings here show that differential risks of severe outcomes from COVID-19 across populations can be in part estimated from the structures and contexts in which the outbreak occurs, for example, a population's quality of health, its access to healthcare and the disparities therein. While vaccine supply continues to be limited for most, and especially low- and middle-income, countries, these population level indicators may help inform optimal allocation.".

An estimated 43 percent of the variability in U.S. COVID-19 mortality is linked with county-level socioeconomic indicators and health vulnerabilities, with the strongest association seen in the proportions of people living with chronic kidney disease and living in nursing homes. The study by Columbia University Mailman School of Public Health researchers suggests that allocating vaccines based on these factors could help minimize severe outcomes, particularly deaths. Results are published in the open-access journal PLOS Medicine.
"It is well known that COVID-19 deaths are concentrated in communities with underlying ...

Researchers have conducted a global study on the effectiveness of recently established protected areas in preventing forest loss
The study explores protected area performance by countries, with South Africa, Cambodia, Latvia, Guatemala, Uruguay, Brazil and New Zealand leading the way in the effectiveness of their protected areas
The research team estimated that overall, protected areas established between 2000-2012 prevented 86,062 square kilometers of forest loss
If all countries had protected areas that were as effective as their top-performing neighbor, then an additional 33,020 square kilometers of forests would have been saved
Machine learning found that agricultural ...

The University of Alberta-led research followed more than 400 infants from the CHILD Cohort Study (CHILD) at its Edmonton site. Boys with a gut bacterial composition that was high in the bacteria Bacteroidetes at one year of age were found to have more advanced cognition and language skills one year later. The finding was specific to male children.
"It's well known that female children score higher (at early ages), especially in cognition and language," said Anita Kozyrskyj, a professor of pediatrics at the U of A and principal investigator of the SyMBIOTA (Synergy in Microbiota) laboratory. "But when it comes to gut microbial ...

Children exposed to elevated levels of air pollution may be more likely to have poor inhibitory control during late childhood and poor academic skills in early adolescence, including spelling, reading comprehension, and math skills. Difficulty with inhibition in late childhood was found to be a precursor to later air pollution-related academic problems. Interventions that target inhibitory control might improve outcomes.
Results of the study by researchers at the Columbia Center for Children's Environmental Health (CCCEH) at Columbia University Mailman School of Public Health and Columbia University Irving Medical Center are published in the journal Environmental ...

Compared with heterosexual smokers, menthol cigarette smoking is higher among lesbian, gay and bisexual cigarette smokers, according to a Rutgers-led study, especially among bisexual and lesbian/gay female cigarette smokers.
The study, published in the journal Nicotine & Tobacco Research, examined national data from 2015 to 2019 of individuals ages 18 years and older by sex and sexual identity and found that among smokers, 54 and 50 percent of bisexual and lesbian/gay females smokers preferred menthol cigarettes, respectively, compared with 39 percent of smokers overall.
This study comes in the wake of plans by the U.S. Food and Drug Administration to ban menthol cigarettes; a move that researchers say is ...

Information-rich optical imaging can provide multidimensional information to enable observation and analysis of a detected target, contributing insights into mysterious and unknown worlds. With its ability to capture dynamic scenes on picosecond—and even femtosecond—timescales, ultrafast multidimensional optical imaging has important applications in the detection of the ultrafast phenomena in physics, chemistry, and biology.
While pump-probe-based ultrafast imaging can acquire high-resolution multidimensional information, it cannot adequately capture unstable or irreversible transient scenes. Fortunately, compressed ultrafast photography (CUP), based ...

A decade after scientists discovered that lab rats will rescue a fellow rat in distress, but not a rat they consider an outsider, new research from the University of California, Berkeley, pinpoints the brain regions that drive rats to prioritize their nearest and dearest in times of crisis. It also suggests humans may share the same neural bias.
The findings, published today, Tuesday, July 13, in the journal eLife, suggest that altruism, whether in rodents or humans, is motivated by social bonding and familiarity rather than sympathy or guilt.
"We have found that the group identity ...

JUPITER, FL - The brain is wired for learning. With each experience, our neurons branch out to make new connections, laying down the circuitry of our long-term memories. Scientists call this trait plasticity, referring to an ability to adapt and change with experience.
For plasticity to happen, our neurons' synapses, or connection points, must constantly remodel and adapt, too. The mechanics underlying neurons' synaptic plasticity have become clearer, thanks to new research from the lab of Scripps Research neuroscientist Sathya Puthanveettil, PhD.
Scientists have learned that synaptic plasticity requires a complex relay from the neuron's cell body to its dendrite arms and its synapse junctions. Like a 24-hour port and highway network, an internal ...

ITHACA, N.Y. - Direct farm marketing efforts, such as farmers markets and roadside stands, are more successful in communities with more nonprofits, social enterprises and creative industries, according to a team including Cornell University researchers, who created a nationwide database of assets to help municipalities craft community-specific development plans.
While many municipalities seek to encourage direct-to-consumer (DTC) marketing - an important factor in farmers' livelihoods - the success of their efforts hinges on a wide array of community resources, or capital assets, with natural and cultural ...

AMHERST, Mass. - Humans have known for over two thousand years that shipworms, a worm-like mollusk, are responsible for damage to wooden boats, docks, dikes and piers. Yet new research from the University of Massachusetts Amherst published in Frontiers in Microbiology reveals that we still don't know the most basic thing about them: how they eat.
"It's unbelievable," says Reuben Shipway, adjunct assistant professor in microbiology at UMass Amherst, research fellow at the Centre for Enzyme Innovation at the University of Portsmouth, UK, and one of the paper's authors. "The ancient Greeks wrote about them, Christopher Columbus lost his fleet due to what he called 'the havoc which the worm had wrought,' and, today, shipworms cause billions of dollars of damage a year."
Shipworms ...
