The 97th Annual American College of Surgeons Clinical Congress

The annual Clinical Congress of the American College of Surgeons was held from Oct. 23 to 27 in San Francisco, and attracted approximately 15,000 participants from around the world, including surgeons and other health care professionals. The conference included panel sessions, postgraduate courses, scientific paper presentations, surgical forum sessions, video-based education presentations, and posters focusing on the latest advances in surgical care. The conference also featured meet-the-expert luncheons and town hall meetings.

Elizabeth M. Pontarelli, M.D., of the Children's Hospital Los Angeles, and colleagues aimed to identify a protein in breast milk that upregulates a cell protein called P-glycoprotein, which is known to decrease the incidence and severity of necrotizing enterocolitis (NEC) in neonates.

"We are currently in the process of identifying this protein in breast milk. We have eliminated a number of contaminants and have narrowed it down to just a few proteins. We are close but not there yet. The next step would be to give the protein to formula-fed animals and evaluate its effectiveness in preventing NEC," Pontarelli said. "Ideally, this protein would be added to formula and would be able to decrease the incidence of NEC in newborn babies. NEC is a serious disease that can be fatal, especially in premature neonates. It doesn't have a good treatment right now, so being able to prevent it could make a significant impact on infant morbidity and mortality."

In another study, Laura Horst Rosenberger, M.D., of the University of Virginia Health System in Charlottesville, and colleagues evaluated whether a rising proportion of infections with resistant organisms was associated with worse mortality in an intensive care unit.

"We found there is a progressive rise in resistant organisms; however, mortality has decreased over time. We believe the impact of a resistant infection provides only a small contribution toward overall mortality and therefore the rising rates of resistant infections do not appear to be a significant factor in the overall mortality of patients in the surgical intensive care unit," Rosenberger said. "We believe these resistant infections are preferentially infecting those with the highest severity of illness and therefore the patients are dying with their infection and not because of it."

Kelly Bettina Currie, M.D., of Bassett Medical Center in Cooperstown, N.Y., and colleagues developed a mathematical model to predict patient specific risk for readmission among those undergoing cardiac surgery to assist with resource allocation and distribution in an effort to prevent readmission.

"Based on our analysis, congestive heart failure, chronic lung disease, time on cardiopulmonary bypass, and body mass index ≥40 were independent predictors of readmission in all patients undergoing cardiac surgery at our institution during the study period," Currie said. "We feel the model we have developed is applicable to everyday practice for patients who have undergone cardiac surgery. However, to make the model even more applicable, we plan to create a similar predictive model from an even larger set of patients."

ACS: Timed Walking Predicts Post-Op Recovery in Elderly

THURSDAY, Oct. 27 (HealthDay News) -- A simple timed walking test can be an effective predictor of postoperative adverse events in elderly patients undergoing cardiac and colorectal surgery, according to a study presented at the Annual Clinical Congress of the American College of Surgeons, held from Oct. 23 to 27 in San Francisco.

ACS: Drug-Resistant Infections Rise but Mortality Declines

WEDNESDAY, Oct. 26 (HealthDay News) -- One surgical intensive care unit (ICU) registered an increased rate of drug-resistant infections between 2000 and 2010 but had a decrease in its all-cause mortality rate, according to a study presented at the annual Clinical Congress of the American College of Surgeons, held from Oct. 23 to 27 in San Francisco.
