Wildfire air pollution may increase risks of hospitalization and death among patients on dialysis

(Press-News.org) Highlights
Among individuals receiving in-center hemodialysis treatment in Washington, Oregon, and California, exposure to wildfire-related air pollution was associated with elevated risks of hospitalization and mortality.
Results from the study will be presented at ASN Kidney Week 2023 November 1–November 5.
Philadelphia, PA (November 2, 2023) — In analyses of data from western US states, increases in wildfire-related air pollution around dialysis clinics were linked to higher rates of hospitalizations and deaths among patients. The research will be presented at ASN Kidney Week 2023 November 1–November 5.
Wildfires, which are increasing in frequency and severity, are major sources of air pollution that may disproportionately impact vulnerable populations such as individuals with kidney failure who are undergoing hemodialysis.
In the study of 79,963 patients who received in-center hemodialysis treatment at 191 Fresenius Kidney Care clinics in Washington, Oregon, and California during 2005–2018, scientists investigated the risk of all-cause hospitalization and mortality associated with wildfire exposure, using 2 metrics: wildfire smoke and wildfire-related fine particulate matter (aerodynamic diameter <2.5 microns).
Exposure to wildfire smoke plume was associated with a 3% higher risk of all-cause hospitalization the following day. The risk of death increased by 5% on the day of exposure. Exposure to wildfire-related fine particulate matter was linked to a similar increase in risk.
“This research sheds light on the health risks faced by hemodialysis patients during wildfire events,” said corresponding author Hyeonjin Song, a PhD student at the University of Maryland, College Park. “The most recent US National Climate Assessment suggests that wildfire seasons will continue to get longer with a corresponding increase in frequency and intensity of wildfire events in response to ongoing climate change. We need to pay attention to how such hazards impact the most vulnerable among us and enhance our preparedness activities to minimize the disease burden.”

The gene-editing technology known as CRISPR has led to revolutionary changes in agriculture, health research and more.
In research published in Nature Catalysis, scientists at Florida State University produced the first high-resolution, time-lapsed images showing magnesium ions interacting with the CRISPR-Cas9 enzyme while it cut strands of DNA, providing clear evidence that magnesium plays a role in both chemical bond breakage and near-simultaneous DNA cutting.
“If you are cutting genes, you don’t want to have only one strand of DNA broken, because the cell can repair it easily without editing. You want both strands to be broken,” said Hong ...

ITHACA, N.Y. – Online grocery carts tend to include less variety and fewer fruits and vegetables than those in a trip to a brick-and-mortar supermarket – but online shoppers are less susceptible to unhealthy impulse buys, according to a new Cornell University study.
In an analysis of nearly 2 million shopping trips, the researchers found that within a given household, Instacart baskets are more similar to each other from week to week than in-store carts, with more than twice as many overlapping items between successive trips to the same retailer.
Nutritionally, however, ...

Generative artificial intelligence tools like ChatGPT, an AI-powered language tool, and Midjourney, an AI-powered image generator, can potentially assist people with various disabilities. These tools could summarize content, compose messages or describe images. Yet the degree of this potential is an open question, since, in addition to regularly spouting inaccuracies and failing at basic reasoning, these tools can perpetuate ableist biases.
This year, seven researchers at the University of Washington conducted a three-month autoethnographic study — drawing on their own experiences as people with and without disabilities — to test AI tools’ utility for accessibility. Though ...

WOODS HOLE, Mass. -- Sharks differ from other fish in many ways, including an apparently remarkable ability to heal from wounds, according to reports of sharks recovering from injuries sustained in the wild. While this healing ability has not yet been documented in controlled laboratory conditions, some of the chemical compounds found in shark skin may have significant biomedical potential.
To investigate this possibility, two dermatology researchers from the Karolinska Institute in Sweden carried out research on a small shark, the spiny dogfish (Squalus acanthias) and other cartilaginous fish species at the ...

Epigenetics, the chemical mechanisms that controls the activity of genes, allows our cells, tissues and organs to adapt to the changing circumstances of the environment around us. This advantage can become a drawback, though, as this epigenetic regulation can be more easily altered by toxins than the more stable genetic sequence of the DNA.

DENVER/Nov. 2 – A scientific analysis published in Veterinary and Comparative Oncology using Golden Retriever Lifetime Study data notes a potential correlation between canine sterilization and hemangiosarcoma development. This startling finding has been previously suggested by experts but still is poorly understood.
The authors note that the likelihood of diagnosing hemangiosarcoma appears consistently low across all sexes and neutering statuses until about eight years of age. Beyond this point, intact and neutered male ...

Excluding herbivores – or reintroducing their predators – may aid restoration efforts in many locations, suggests a new meta-analysis of more than 600 global studies. According to the analysis, herbivores at restoration sites reduced vegetation abundance by 89%, on average, a larger effect than they had at relatively undisturbed sites. Herbivores also suppressed plant diversity at these locations. Vegetation is a primary foundation of most ecosystems. However, in many, it has been dramatically degraded, contributing to the loss of biodiversity and ...

Driven in part by large-scale atmospheric climate modes, the Southern Hemisphere accounts for more than 95% of the recent decline in global water availability, according to a new study. Global land water availability has varied due to climate change and increased human water use. Although this crucial resource underpins livelihoods, socioeconomic development, and ecosystems worldwide, it remains unclear how water availability has changed in recent decades and what is driving these changes at a global scale. Yongqiang Zhang and colleagues combine various data, including streamflow observations of large river basins of ...
