Rising Temperatures Could Lead to Greater Care Needs for MS Patients 4.6 (12)
Rising average temperatures may lead to a worsening of symptoms in people with multiple sclerosis (MS) and a greater need for hospital care, according to a preliminary study by researchers in the U.S.
“Our study suggests that warming trends could have serious health implications over the long term for people living with MS,” Holly Elser, PhD, an epidemiologist at Stanford University School of Medicine in California and a study author, said in a press release.
Many people with MS experience a temporary worsening of symptoms, such as fatigue or weakness, when they overheat in hot weather. These changes are linked to heat sensitivity, and can result from slight increases in core body temperature that further affect the ability of nerves to conduct electrical impulses, especially if the nerve fibers are damaged as happens in MS.

A new review of existing evidence proposes eight hallmarks of environmental exposures that chart the biological pathways through which pollutants contribute to disease: oxidative stress and inflammation, genomic alterations and mutations, epigenetic alterations, mitochondrial dysfunction, endocrine disruption, altered intercellular communication, altered microbiome communities, and impaired nervous system function.
The study by researchers at Columbia University Mailman School of Public Health, Ludwig Maximilian University, and Hasselt University is published in the journal
Cell. Every day we learn more about how exposure to pollutants in air, water, soil, and food is harmful to human health, says senior author Andrea Baccarelli, MD, PhD, chair of Environmental Health Sciences at Columbia Mailman School. Less understood, however, are the specific biological pathways through which these chemicals inflict damage on our bodies. In this paper, we provide a framework to

NIEHS-Funded Study Finds Graphene Nanochannel Filters Hold Promise for Contaminant Clean-Up
The March 2021 issue of Environmental Factor, a monthly newsletter published by the National Institute of Environmental Health Sciences (NIEHS), includes an item entitled New graphene nanochannel filters hold promise for contaminant clean-up. See https://factor.niehs.nih.gov/2021/3/papers/dert/index.htm#a2 According to the item, an NIEHS-funded study found a new strategy to design nanomaterials to filter contaminants better from water. To improve the usefulness of graphene oxide nanosheets for filtering contaminants from liquid, the researchers modified how the sheets are assembled, reduc[ing] the distance water must
