MedicalResearch.com Interview with: Jordan J. Karlitz, MD Staff Gastroenterologist Southeast Louisiana Veterans Health Care System Associate Professor, Division of Gastroenterology Director, GI Hereditary Cancer and Genetics Program, Tulane University School of Medicine MedicalResearch.com: What is the background for this study? Response: Currently, there is debate over whether average-risk colorectal cancer screening should begin at age 45 or 50. Given this controversy, we sought to conduct a colorectal cancer incidence rate analysis by yearly-age, as opposed to age range blocks (i.e. 30-39, 40-49 etc.) as has been done in the past. We believed that this type of "high definition" analysis would allow a better understanding of incidence rates of those approaching or at screening in age. We were particularly interested in the transition from age 49 to 50 as this is when average risk screening has historically been recommended. (more…)

MedicalResearch.com Interview with: Giovanni Piedimonte, MD, FAAP, FCCP Vice President for Research Institutional Official Professor of Pediatrics Tulane University MedicalResearch.com: What is the background for this study? Response: We have been testing the hypothesis that, when a pregnant woman catches a common cold with a virus called respiratory syncytial virus (RSV), viral particles can spread from the mother’s respiratory tract to the unborn child via the placenta. Preliminary data in animal models suggest that this is possible, and might cause changes in lung growth predisposing the offspring to develop asthma after birth. Recently, also human data have supported this theory. However, an essential step to conclusively demonstrate vertical transmission of respiratory viruses was the confirmation that human placentas can be infected and allow the transmission of such germs, which is the main finding of this study.

MedicalResearch.com Interview with: Dr. Lu Qi MD PhD Department of Epidemiology, School of Public Health and Tropical Medicine Tulane University New Orleans, LA 70112 Department of Nutrition, Harvard T.H. Chan School of Public Health, Channing Division of Network Medicine, Department of Medicine, Brigham and Women's Hospital and Harvard Medical School Boston, MA 02115 Yoriko Heianza RD, PhD Department of Epidemiology, School of Public Health and Tropical Medicine, Tulane University New Orleans, LA MedicalResearch.com: What is the background for this study? What are the main findings? Response: Growing data suggest that antibiotic exposure is associated with a long-lasting alteration in gut microbiota, and may be related to subsequent cardiovascular disease (CVD). We investigated associations of duration of antibiotic use in different phases of adulthood (young, middle and late adulthood) with the CVD incidence among women at usual risk. This new analysis from the Nurses’ Health Study shows that women who take antibiotics for long periods, especially during more recent adulthood (such as in middle- and late adulthood) had a higher risk of CVD in later life.

MedicalResearch.com Interview with: M. Pia Chaparro, MS, PhD Assistant Professor Department of Global Community Health and Behavioral Sciences School of Public Health and Tropical Medicine Tulane University New Orleans, LA 70112 MedicalResearch.com: What is the background for this study? What are the main findings? Response: In 2009, the WIC program changed the food packages participants receive to better align them with federal dietary guidelines. These changes included the addition of fruits, vegetables, and whole grains; a reduction in the amount of dairy and juice; and a calibration in formula amounts to match infants’ age and needs. We found that this change in the food package was associated with a 10-12% lower obesity risk at age 4 years among children who participated in WIC in Los Angeles County continuously from birth until age 4.
