Healthcare costs for infections linked to bacteria in water supply systems are rising
September 12, 2016 10:38 AM - Tufts University via EurekAlert!

A new analysis of 100 million Medicare records from U.S. adults aged 65 and older reveals rising healthcare costs for infections associated with opportunistic premise plumbing pathogens--disease-causing bacteria, such as Legionella--which can live inside drinking water distribution systems, including household and hospital water pipes.

A team led by researchers from the Friedman School of Nutrition Science and Policy at Tufts University and Tufts University School of Medicine found that between 1991 and 2006, more than 617,000 hospitalizations related to three common plumbing pathogens resulted in around $9 billion in Medicare payments--an average of $600 million a year. The costs may now exceed $2 billion for 80,000 cases per year, write the study authors. Antibiotic resistance, which can be exacerbated by aging public water infrastructure, was present in between one and two percent of hospitalizations and increased the cost per case by between 10 to 40 percent.

Selecting the right house plant could improve indoor air
August 24, 2016 07:30 AM - American Chemical Society via EurekAlert!

Indoor air pollution is an important environmental threat to human health, leading to symptoms of "sick building syndrome." But researchers report that surrounding oneself with certain house plants could combat the potentially harmful effects of volatile organic compounds (VOCs), a main category of these pollutants. Interestingly, they found that certain plants are better at removing particular harmful compounds from the air, suggesting that, with the right plant, indoor air could become cleaner and safer. 

The researchers are presenting their work today at the 252nd National Meeting & Exposition of the American Chemical Society (ACS). ACS, the world's largest scientific society, is holding the meeting here through Thursday. It features more than 9,000 presentations on a wide range of science topics. A brand-new animation on the research is available at http://bit.ly/ACSindoorairpollution.

"Buildings, whether new or old, can have high levels of VOCs in them, sometimes so high that you can smell them," says Vadoud Niri, Ph.D., leader of the study.

Thousands of Homes Keep Flooding, Yet They Keep Being Rebuilt Again

Katherine Bagley, Yale Environment 360

The U.S. National Flood Insurance Program, which holds policies for more than 5 million homes, is $23 billion in debt after a string of natural disasters this century. As climate change further strains the program, analysts say it is time to shift its focus from rebuilding to mitigating risk.

More than 2,100 properties across the U.S. enrolled in the National Flood Insurance Program have flooded and been rebuilt more than 10 times since 1978, according to a new analysis of insurance data by the Natural Resources Defense Council (NRDC). One home in Batchelor, Louisiana has flooded 40 times over the past four decades, receiving $428,379 in insurance payments. More than 30,000 properties in the program, run by the Federal Emergency Management Agency, have flooded multiple times over the years. Those homes, known as “severe repetitive loss properties,” make up just 0.6 percent of federal flood insurance policies. But they account for 10.6 percent of the program’s claims — totaling $5.5 billion in payments.

The new data illustrates the serious problems facing the nation’s flood insurance program. The National Flood Insurance Program (NFIP), which currently provides policies for more than 5 million American homes, is $23 billion in debt following a string of major natural disasters over the last decades, including as Hurricanes Katrina and Sandy.
