A recent analysis from the Tribal Tobacco Use Project Survey of 964 urban American Indian residents in Hennepin County and Ramsey County in 2011 found a high prevalence of cigarette smoking among persons aged 25-44 years (72 percent). Among all survey respondents 59 percent were current smokers, 19 percent were former smokers and 22 percent had never smoked.

Furthermore, the smoking rate and secondhand smoke exposure is still high despite being covered by Minnesota’s strong smoke-free law.

Study shows CDC’s PulseNet cost-effectively prevents illness and saves money

Editor’s note: This post originally appeared on the School of Public Health’s blog.

A study from the School of Public Health shows that over the past 20 years, PulseNet, a foodborne outbreak surveillance system, has justified its expense by preventing thousands of bacterial infections and saving millions of dollars in medical and productivity costs.

The study, led by Professor Craig Hedberg and economist Robert Scharff from Ohio State University, was recently published in the American Journal of Preventative Medicine.

“If it weren’t for the activity of PulseNet, we’d actually have seen an increase in infections, such as Salmonella, over time in the United States,” says Hedberg.

Research snapshot: UMN researchers develop unique method to analyze oxidative DNA damage in age-related macular degeneration

The triple quadrupole mass spectrometer, part of the Masonic Cancer Center’s Analytical Biochemistry Shared Resource, was used for the analysis of mitochondrial DNA adducts by liquid chromatography nanoelectrospray-tandem mass spectrometry.

Age-related macular degeneration (AMD) is the leading cause of blindness among older adults in the developed world. To better understand the mechanisms of AMD to hopefully one day prevent and treat it, researchers in the University of Minnesota’s School of Public Health and the Department of Ophthalmology & Visual Neurosciences have developed a unique method for analyzing oxidative damage in tiny amounts of DNA from the human eye. Results of the study were recently published in Scientific Reports.

Led by Irina Stepanov, Ph.D., assistant professor in the School of Public Health and Masonic Cancer Center, University of Minnesota, the team used a highly sensitive method that can detect specific oxidative modifications in DNA. They used this method to analyze mitochondrial DNA from retinal pigment epithelium, a single cell layer from eye tissues, and compared results between samples that came from healthy eyes and those with age-related macular degeneration.

SPH report: Health status of American Indians/Alaska Natives continues to decline – Part 3

Editor’s note: This is the third post in a three part series. The first and second posts can be found here and here. A summary of the report can be found here. The complete report can be found here.

Throughout this series we’ve provided you with an overview of a recent report by Linda Frizzell, Ph.D., assistant professor in the University of Minnesota School of Public Health that shows the overwhelming and persistent health disparities American Indians and Alaska Natives (AI/AN) face.

The conclusion of the series will highlight some additional challenges AI/ANs endure, and Frizzell will provide some recommendations for policymakers to improve AI/AN health.

SPH report: Health status of American Indians/Alaska Natives continues to decline – Part 2

Editor’s note: This is the second post in a three part series. The first post can be found here. A summary of the report can be found here. The complete report can be found here.

Yesterday we discussed the persistent health inequities American Indians and Alaska Natives (AI/AN) face today brought forth in a new report by Linda Frizzell, Ph.D., assistant professor in the University of Minnesota School of Public Health.

The Indian health system (IHS) is unlike any other. It serves some of the poorest, sickest and most remote populations in the United States. Each tribe’s culture guides their elected leadership to meet their respective needs in this complex environment.
