WATCHFUL WAITING: DEFERRED LADD PROCEDURE IN PATIENTS WITH CONGENITAL HEART DISEASE, HETEROTAXY SYNDROME, AND KNOWN INTESTINAL MALROTATION(The University of Arizona., 2015-04-14)Purpose: Infants born with Heterotaxy Syndrome (HS) often have intestinal malrotation in addition to severe congenital heart disease (CHD). Given the catastrophic risk of midgut volvulus, where the vascular supply to the gut is cut off causing necrotic bowel and possible future short‐gut syndrome following surgery, an elective Ladd procedure is recommended at the first diagnosis of malrotation. In patients with severe CHD, however, the risk of complications from prophylactic surgery is high, especially in infancy prior to stable cardiac palliation. This study sought to determine whether deferring a Ladd procedure during the first six months of life in infants with CHD is safe by focusing on the incidence of volvulus in the HS population, morbidity of volvulus and morbidity of an elective Ladd procedure. Methods: Medical records of patients with HS and intestinal malrotation at Phoenix Children’s Hospital from 2006‐2011 were reviewed. Stage of heart surgery, severity of heart disease, diagnosis of intestinal malrotation, and timing of Ladd procedure if applicable were recorded. Results: 31 patients with HS and intestinal malrotation were identified. Of the 31, 9 had a Ladd procedure prior to six months of age, 2 for volvulus and the other 7 either electively or for less severe GI symptoms that were not suggestive of volvulus. The other 22 did not have a Ladd procedure prior to six months of age. There was one death (1/22) from a non‐gastrointestinal cause in a patient who had not undergone a Ladd procedure. There were no deaths in the 9 patients who underwent a Ladd procedure (0/9). Conclusions: Given the low overall incidence of volvulus in HS, and with continued vigilance for obstructive symptoms, this study suggests that delaying the Ladd procedure in asymptomatic patients with HS and CHD and intestinal malrotation is safe. Watchful waiting may reduce the incidence of cardiac complications during the Ladd procedure by allowing for stabilizing cardiac surgical palliation prior to elective abdominal surgery.
“WATCHING” WHAT WE EAT: WHAT TELEVISION IS MODELING(The University of Arizona., 2015-04-09)Background: Obesity has transitioned from an individual health concern to being a national problem with almost two‐thirds of the adult population in the United States now overweight or obese1. Television potentially provides a medium in which to model healthy and unhealthy behaviors to millions of viewers each week. Although there is no quick solution to obesity, promoting and normalizing healthy lifestyles in today’s most viewed shows may be one tool to help combat an obesogenic lifestyle. Research Question: To what degree do today’s most popular sitcoms model healthy and unhealthy behaviors? Methods: A scorecard with 11 behaviors (6 healthy and 5 unhealthy) was created using publically published guidelines from the Center for Disease Control (CDC)1,2,3, World Health Organization (WHO)4, and the United States Department of Agriculture (USDA)5,6. The top three sitcoms for the 2013‐2014 season, as determined by TV Guide, were viewed and analyzed by one evaluator. These included The Big Bang Theory, The Millers, and Modern Family7. Results: In total, 898 unhealthy behaviors and 532 healthy behaviors were portrayed. The Big Bang Theory demonstrated the most behaviors overall and had the most favorable ratio of healthy to unhealthy behaviors at 1/1.1, compared to 1/3.8 for The Millers and 1/3.2 for Modern Family. The most common unhealthy behavior viewed was beverage choice with 492 occurrences. One of the least portrayed healthy behaviors was moderate physical activity with only 47 instances. In two of the three shows, there were remarkably few examples of fruit and vegetable consumption. Conclusion: Today’s top three sitcoms expose their viewers to many healthy and unhealthy behaviors during the span of a 22‐minute show. Significantly more unhealthy behaviors were portrayed than healthy behaviors. The most common unhealthy behavior centered on beverage choice. This is a behavior that can easily be adjusted to promote a healthier lifestyle. Additionally, food content could reflect more healthy choices. Television shows reach millions of viewers each week and may prove to be a useful tool in helping to reinforce and normalize healthy lifestyle choices.
