Purpose: The purpose was to test a published model of body image in the bariatric surgery patient in the clinical office setting.

Background: A model was created based on clinical observations during field work and the literature. It focuses on five concepts of body image: body attitude, body checking, appearance orientation, perceived body size, and perceived body space.

In response to growing interest in human exposure to perfluorinated compounds (PFCs), the state of Minnesota measured and reported PFC concentrations in fish collected from the Minneapolis-St. Paul area. To better determine the geographical distribution of PFC contamination throughout Minnesota, fish were collected from 59 lakes throughout the state and several areas along the Mississippi River.

Article Synopsis
  • A new method using solid phase extraction, liquid chromatography, and tandem mass spectrometry is developed to measure 10 perfluorinated compounds (PFCs) in fish fillets, specifically bluegill sunfish from Minnesota and North Carolina.
  • * Four PFCs were commonly detected, with perfluorooctane sulfonate (PFOS) being the most prevalent, showing varying levels of contamination across different locations in Minnesota and North Carolina.
  • * The study's findings indicate significant PFC contamination in fish from areas without known historical sources, highlighting a broader concern over PFCs in freshwater fish populations.

A method for the analysis of 10 perfluorinated compounds (PFCs) in whole fish homogenate is presented and applied to 60 fish samples collected from the Ohio, Missouri, and upper Mississippi Rivers in 2005. Method accuracy ranged between 86 and 125% with limits of quantitation between 0.2 and 10 ng/g wet weight.
