Trace metals screening process of devices used for the collection, analysis, and storage of biological specimens
Ward CD , Williams RJ , Mullenix K , Syhapanha K , Jones RL , Caldwell K . At Spectrosc 2018 39 (6) 219-228 The Centers for Disease Control and Prevention’s (CDC) Environmental Health Laboratory uses modified versions of inductively coupled plasma mass spectrometry (ICP-MS) analytical methods to quantify metals contamination present in items that will come into contact with patient samples during the preanalytical, analytical, and postanalytical stages. This lot screening process allows us to reduce the likelihood of introducing contamination which can lead to falsely elevated results. This is particularly important when looking at biomonitoring levels in humans which tend to be near the limit of detection of many methods. The fundamental requirements for a lot screening program in terms of facilities and processes are presented along with a discussion of sample preparation techniques used for lot screening. The criteria used to evaluate the lot screening data to determine the acceptability of a particular manufacturing lot is presented as well. As a result of lot testing, unsuitable manufactured lots are identified and excluded from use. |
Promotora de salud: promoting folic acid use among Hispanic women
deRosset L , Mullenix A , Flores A , Mattia-Dewey D , Mai CT . J Womens Health (Larchmt) 2014 23 (6) 525-31 BACKGROUND: The U.S. Public Health Service recommends that all women in the United States capable of becoming pregnant consume 400 mug of folic acid daily to reduce their risk of having a pregnancy affected by a neural tube defect (NTD). However, disparities exist in the consumption of folic acid, with Hispanic women having lower rates of folic acid consumption than non-Hispanic white women. METHODS: A community-based feasibility study was designed to assess the utility of the promotora de salud model to promote consumption of multivitamins containing folic acid for the prevention of NTDs among Spanish-speaking Hispanic women in North Carolina. The study consisted of an educational intervention given by a promotora (a lay, community health worker), with data collection occurring at baseline and four months post-intervention to measure changes in knowledge and behavior. Overall, 52% (n=303) of participants completed all components of the study. RESULTS: Self-reported daily multivitamin consumption increased from 24% at baseline to 71% four months post-intervention. During the same time frame, awareness of folic acid increased from 78% to 98% and knowledge of the role of folic acid in the prevention of birth defects increased from 82% to 92%. CONCLUSIONS: The results of this study indicate that the promotora de salud model may be effective in reaching a subpopulation of women with the folic acid message. Additional studies with larger population sizes are warranted to validate these findings. |
