Climate change increases kidney stones

(When the daily temperature rises, the number of patients seeking treatments for kidney stones also increases. In a study that could reflect both and predict a global warming effect on human health, a research team found an association between hot days and kidney stones at 60,000. multiplying in some US cities along with climate change.

'We found that when the day temperature increased, there was a rapid increase in the number of patients with kidney stones that could appear 20 days later , ' said lead author Gregory E.Tasian, MD. , M.Sc., MSCE, an expert on urology and an epidemiologist at Children's Hospital of Philadelphia (CHOP), is an employee of the Hospital's Kidney Center as well as the Brand Center. Clinical results of the hospital (Hospital's Center for Pediatric Clinical Effectiveness - CPCE) said.

Tasian, senior researcher Ron Keren, MD, MPH, also belongs to CHOP and CPCE centers, and colleagues from other centers presented their research results in the Journal of Perspective of Power. Environmental Health Perspectives, a National Research Institute for Environmental Health Sciences (National Institute of Environmental Health Sciences). Urological diseases in the America Project, supported by the National Research Institute for Diabetes, Digestion and Kidney Disease, sponsored this study.

The research team analyzed medical records of more than 60,000 adults and children with kidney stones from 2005 to 2011 in Atlanta, Chicago, Dallas, Los Angeles and Philadelphia, in connection with data on weather. Tasian and colleagues described the risk of gravel for adequate temperature relief in each city. When the day temperature rises above 50 degrees Fahrenheit (10 degrees Celsius), the risk of developing kidney stones increases in all cities except Los Angeles. The delay between the high temperature of the day and the appearance of kidney stones is very short, peaking within 3 days under hot sunny days.

'These findings indicate potential public health effects associated with climate change , ' Tasian said. However, Tasian warned, ' although 11% of Americans are having kidney stones, most others do not. That means higher temperatures increase the risk of kidney stones in people who are more likely to form kidney stones . ' Higher temperatures contribute to dehydration, which leads to higher levels of calcium and other minerals in the urine that promote kidney stone formation.

This painful disease forced half a million patients to go to emergency rooms in the US, kidney stones increased significantly worldwide in the last three decades. While stones are more common in adults, the number of babies developing kidney stones has increased at an amazingly high rate over the past 25 years. The factors that contribute to kidney stones are still unknown, but may be affected by changes in diet and water intake . When stones are unable to dig out of the body, surgery may be necessary.

The team also found that very low outdoor temperatures increase the risk of kidney stones in three cities: Atlanta, Chicago and Philadelphia. The authors argue that cold weather keeps people more in the home, warmer indoor temperatures, changes in diet and reduced physical activity may increase the risk of kidney stones.

The researchers concluded that the number of hot days in a year could predict the risk of kidney stones better than the average annual temperature. Atlanta and Los Angeles share the same annual temperature (63 degrees F or 17 degrees C), but Altlanta has much hotter days than Los Angeles, with nearly double the rate of kidney stones.

Tasian added that the above five US cities have a climate that represents all regions of the world, further research can be done to understand what the current research has done. . Other studies can analyze the types of risk models in different population groups, including children, represented by a small sample size in this study.

The broader context of research is in the pattern of global warming. The authors note that other scientists have reported overall global temperatures between 2000 and 2009 to be 82% higher than temperatures over the past 11,300 years. Furthermore, the increase in greenhouse gas emissions is expected to increase the earth's average temperature by 2 to 8 degrees F (equivalent to 1 to 4.5 degrees Celsius) by 2100. "Billion Kidney stones have increased over the past 30 years, and we can predict this trend will continue, increasing in both quantity and size, as the temperature increases, " concluded Tasian. "With some experts predicting that extreme temperatures will become popular 30 years later, children will suffer the burden of climate change."
