Risk of Chronic Kidney Disease May Increase Due To Polluted Air

Looking at areas that are heavily polluted versus areas that are less polluted, you will find more chronic kidney diseases in the heavily polluted areas.

Polluted air increases the risk of chronic kidney disease (CKD) which occurs when a person’s kidneys are damaged, or cannot filter blood properly, researchers, including one of Indian origin, have found.

The study highlighted that people with diabetes, obesity, high blood pressure or heart disease are at an increased risk of developing CKD.

Apart from PM2.5, air pollution also contains heavy metals such as lead, mercury and cadmium — all of which are known to negatively affect the kidneys.

Researchers from the University of Michigan in the US, warn high-risk patients who live in heavily populated areas to recognise the danger and take precautions.

“Similar to smoking, air pollution contains harmful toxins that can directly affect the kidneys,” said lead author Jennifer Bragg-Gresham, from the varsity.

“Kidneys have a large volume of blood flowing through them, and if anything harms the circulatory system, the kidneys will be the first to sense those effects,” she added.

Previous studies have shown that polluted air increases the risk of respiratory problems such as asthma, organ inflammation, worsening of diabetes and other life-threatening conditions.

The new study, published in the journal PLOS ONE, examined several prior studies on the issue.

Looking at areas that are heavily polluted versus areas that are less polluted, you will find more chronic kidney diseases in the heavily polluted areas, said co-author Rajiv Saran, a nephrologist at the varsity.

“In heavily polluted areas, consider wearing masks that cover your nose and mouth, limit hours outside and limit long hours commuting to work in high traffic as well,” cautioned Saran, adding that the risk should be taken seriously. (IANS)

Researchers Develop Wearable Device to Measure Wearer’s Physiological Response to Environment

The team says the aim of Project Coolbit is to create a personalised comfort model for each wearer, as well as crowdsourcing environmental data in the city in real-time.

Researchers are developing a wearable device that aims to provide individualised information while gathering environmental data.

According to researchers, the device can measure the wearer’s physiological response to their immediate environment.

“We have added some sensors to the Fitbit watches that get information from air temperature and humidity, but also from the physiological response of the individual in that environment, such as your heart rate, your skin temperature, and your skin humidity,” said Negin Nazarian from UNSW.

“We have also developed some apps where you can interact with and tell us how you feel about the environment, so that way we can develop a methodology and a solution that is personalised and not one-size-fits-all,” Nazarian added.

The team says the aim of Project Coolbit is to create a personalised comfort model for each wearer, as well as crowdsourcing environmental data in the city in real-time.

“So your wearable already knows your personal comfort model, it knows your preference of the environment, the type of activities you like and some information about your physiological response,” the team said.

A Coolbit user could create a personalised heat safe route for a run, based on the previous information received by the wearable, according to the researcher.

“It also knows, based on the environmental information that other parties may give about the cities, the climate of the city,” the researchers said. (IANS)
