Gender Specific Differences In The Pros And Cons Of Smoking Among Current Smokers In Eastern Kentucky: Implications For Future Smoking Cessation Interventions, Dana A. Hazen, David M. Mannino, Richard Clayton

Preventive Medicine and Environmental Health Faculty Publications

This study investigated gender differences in the perceived “pros” and “cons” of smoking using the constructs of decisional balance (DB) and stage of change from the Transtheoretical Model. The population distribution for stage of change among a population-based, cross-sectional survey of 155 current smokers over 40 years was: precontemplation (22.6%), contemplation (41.9%), preparation (35.5%). Results of stepwise regression models indicated significant gender differences in DB were in the preparation stage of change; scores on the DB measure increased 3.94 points (95% CI: 1.94, 5.93) for male smokers. Interventions targeting the “pros” and “cons” of smoking may need to be gender …

Genetic Variation In Genes For The Xenobiotic-Metabolizing Enzymes Cyp1a1, Ephx1, Gstm1, Gstt1, And Gstp1 And Susceptibility To Colorectal Cancer In Lynch Syndrome, Mala Pande, Christopher I Amos, Daniel R Osterwisch, Jinyun Chen, Patrick M Lynch, Russell Broaddus, Marsha L Frazier

Faculty, Staff and Student Publications

Individuals with Lynch syndrome are predisposed to cancer due to an inherited DNA mismatch repair gene mutation. However, there is significant variability observed in disease expression likely due to the influence of other environmental, lifestyle, or genetic factors. Polymorphisms in genes encoding xenobiotic-metabolizing enzymes may modify cancer risk by influencing the metabolism and clearance of potential carcinogens from the body. In this retrospective analysis, we examined key candidate gene polymorphisms in CYP1A1, EPHX1, GSTT1, GSTM1, and GSTP1 as modifiers of age at onset of colorectal cancer among 257 individuals with Lynch syndrome. We found that subjects heterozygous for CYP1A1 I462V …

The Interplay Of Obesity And Asthma, James Plumb, Rickie Brawer, Nancy Brisbon

Department of Family & Community Medicine Faculty Papers

The relationships, interactions, and association between obesity and asthma are complex, and are active sources of hypotheses and research. An association between obesity and asthma has been reported in many studies, although considerable debate about the existence of the association and its meaning still exists. Potential associative relationships may result from genetics, immune system modifications, and mechanical mechanisms. The rising prevalence of asthma and obesity in children and adults, and the significant morbidity from both, makes it imperative that clinicians recognize the importance of weight management in patients with and without asthma.

Reduction In The Incidence Of Type 2 Diabetes With Lifestyle Intervention Or Metformin., William C. Knowler, Elizabeth Barrett-Connor, Sarah E. Fowler, Richard F. Hamman, John M. Lachin, Elizabeth A. Walker, David M. Nathan, P. G. Watson, J. T. Mendoza, K. A. Smith, J. Caro, B. Goldstein, C. Lark, L. Menefee, L. Murphy, C. Pepe, J. M. Spandorfer

Department of Medicine Faculty Papers

BACKGROUND: Type 2 diabetes affects approximately 8 percent of adults in the United States. Some risk factors--elevated plasma glucose concentrations in the fasting state and after an oral glucose load, overweight, and a sedentary lifestyle--are potentially reversible. We hypothesized that modifying these factors with a lifestyle-intervention program or the administration of metformin would prevent or delay the development of diabetes.

METHODS: We randomly assigned 3234 nondiabetic persons with elevated fasting and post-load plasma glucose concentrations to placebo, metformin (850 mg twice daily), or a lifestyle-modification program with the goals of at least a 7 percent weight loss and at least …

Permeabilization Of Cochliomyia Hominivorax (Diptera: Calliphoridae) Embryos, Dennis Berkebile, Jan Chirico, Roger A. Leopold

Department of Entomology: Faculty Publications

Embryos of the primary screwworm, Cochliomyia hominivorax (Coquerel), were successfully permeabilized for use in subsequent cryopreservation studies. Mortality was greater for eggs incubated for<5 h before treatment. The mean survival of embryos to first instars was 55.7, 61.1, and 62.6% when the embryos were incubated for 5, 5.5, and 6 h before treatment, respectively. The survival to the pupal and adult stages was low. An improved media for culturing the embryos during and immediately after treatment needs to be devised and the procedure for rearing the larval stages also needs to be altered to improve survival for emerging adults.
