From June 18-July 6, Emory Medishare's faculty surgeons and anesthesiologists; medical students; surgery residents; and mid-level practitioners provided surgical care to residents of Haiti's Plateau Central, the poorest and most medically underserved region in the country. Despite such conditions as oppressive heat, an OR that functioned on a diesel generator, minimal lighting, intermittent power outages, and an autoclave mishap that required surgical instruments to be sterilized off the premises for the first two days of the trip, the team managed to perform 65-to-70 procedures.

"The types of things we take for granted in U.S. hospitals, like ORs with environmental controls, automated scrub sinks, and having enough basic supplies like surgical gloves, are not always the case in a country as impoverished as Haiti," says general surgeon Dr. Jahnavi Srinivasan, who has participated in Emory Medishare's summer trips to Haiti's L'Hôpital Sainte-Thérèse de Hinche since 2010. "It's as if the physical environment consistently conspires against the type of work we do. Compassion for those severely in need is what gets us there, but thinking on our feet and doing our best with not nearly enough is what makes it work."

Born as an affiliate of Project Medishare, a non-profit consortium of U.S. medical schools dedicated to providing comprehensive health and development services in Haiti, Emory Medishare made its first trip to Hinche in 2008. Beyond the objective of providing the highest quality treatment possible to a rural Haitian patient population that has little access to medical care, the heart of Emory Medishare is the interaction between faculty leaders, their resident assistants, and medical students, who receive credit for their involvement as a global surgery elective. Months before they set foot in Haiti, medical students have the responsibility of raising funds to finance the trips, making travel arrangements, recruiting physicians and staff, and stockpiling medical supplies and pharmaceuticals. On the ground, the 3rd and 4th year medical students meet patients at first presentation and diagnosis, follow them to the operating room, observe and assist on procedures, coordinate all facets of postoperative care, and provide for discharge.

In addition to the medical students and physician staff, the clinical teams include volunteer, Haitian expatriate ICU nurses from Emory University and Grady Memorial hospitals that assist with translating and caring for patients. "The nurses are great liaisons, not only because they speak the language, but because they share a cultural heritage with the patients and the hospital staff," Dr. Srinivasan says. "They are very focused on giving back to their people."

For the first week of the trip, Dr. Srinivasan and the medical students were joined by urologist Dr. Jeff Carney, Medishare-veteran and anesthesiologist Dr. Cinnamon Sullivan, anesthesiology resident Dr. Elizabeth Fuacher, and retired Emory professor and former pediatric surgery chief Dr. Richard Ricketts. "I'm always thinking of how we can involve other specialties in these trips," says Dr. Srinivasan. "Dr. Ricketts made it easy. He approached me at his retirement party and was very emphatic about volunteering. While we've been able to do many of the simple pediatric surgeries over the years, we just aren't used to routinely operating on children. Pediatric surgical care is scarce in Haiti, and Dr. Ricketts is just so fantastic. We were lucky to have him."

In addition to Dr. Carney, the staff for the second week included general surgery resident Dr. Blayne Sayed, general surgeons Dr. Joe Sharma (his third Medishare trip) and Dr. Carla Haack, anesthesiologist Dr. Grant Lynde, and anesthesiology resident Dr. Caitlin Sutton. The third and final week was devoted to surgery follow-up clinic and was supervised by Dr. Barbara Pettitt, director of medical student education for the Department of Surgery, with assistance from Dr. Haack and the 4th year medical students. Approximately 80% of the surgical patients from the prior two weeks returned to the hospital to be seen.

The most common procedures performed during the trip were inguinal hernia tissue repairs, open prostectomies, hydrocele repair, and removal of enlarged lipomas, cysts, benign soft tissue tumors, and other subcutaneous masses.

Dr. Srinivasan's desire to expose medical students and residents to global health issues has remained constant on her Medishare trips, though other motivations have shifted. "When I first started going, I was partially motivated by the idea of placing myself in an environment that would truly test my ability to rise to a challenge. These days, that's just a given. Now—and I believe I can speak for all of my colleagues—our passion is for the Haitian people and knowing that there is a population of patients who will benefit from care that they would be unlikely to receive if not for our us. It's great watching how that realization impacts our students, and it's wonderful to have the opportunity to mentor them through an experience that forms the foundation for a career in global health for many of them."

Dr. Coopersmith and Dr. Ford receive multi-PI R01 to study alcoholism and sepsis

Compared to septic patients with no significant history of alcoholism, septic patients with chronic alcohol abuse have increased severity of multiple organ dysfunction and mortality. Dr. Craig Coopersmith, associate director of the Emory Critical Care Center and vice chair of research for the Emory Department of Surgery, and Dr. Mandy Ford, scientific director of the Emory Transplant Center, have received a collaborative R01 from the NIH to study the impact of chronic alcohol abuse on the pathophysiology of sepsis. The team hopes to determine the mechanisms underlying mortality in sepsis following chronic alcohol ingestion with the goal of tailoring an appropriate therapeutic approach for these patients.

This study is in addition to Dr. Coopersmith and Dr. Ford's prior, ongoing R01, which is investigating the effect of pre-existing cancer on sepsis. Both studies benefit from Dr. Coopersmith's experience studying the consequences of and adaptation to sepsis and shock and Dr. Ford's focus on examining pathologic immune responses. For example, Dr. Coopersmith's R01 study "Mechanisms of Intestinal Integrity in Sepsis and Shock" has just been renewed for a third cycle of funding by the NIH, and Dr. Ford is the PI of several studies concerned with T cell activation, programming, and memory generation following transplantation.

The co-PIs have created a murine model that replicates the heightened mortality seen in alcoholic septic patients relative to septic patients with no prolonged alcoholism. While the function and state of the majority of organs are similar between alcohol-fed and water-fed septic mice, the team has found that both gut integrity and components of the immune system are severely dysregulated in the alcohol-fed group. It has become clear that abnormalities in gut integrity and the immune response are exacerbated in alcohol-fed septic mice, and that certain mechanisms appear to be specific to the combination of sepsis and chronic alcohol usage. Specifically, multiple anomalies exist with the combination of chronic alcohol ingestion and sepsis that are absent from either chronic alcohol ingestion or sepsis in isolation.

The new study will seek to understand these mechanisms by examining both gut integrity (apoptosis, permeability, proliferation, and villus length) and the host immune response, with a primary focus on CD4+ T cells and NK cells. The team will examine the crosstalk between the gut and the immune system to determine how shifting gut integrity and altered immune response affect each other in alcohol-fed septic mice. Considering that sepsis affects over 100,000 patients with alcohol use disorders annually and is a very costly, highly lethal disease, gaining an understanding of the physiological interactions underlying mortality in sepsis following chronic alcohol ingestion has significant public health implications.

Analysis of outcomes for early stage lung cancer surgery could yield better treatment tactics

The Agency for Healthcare Research and Quality (AHRQ) has notified Emory cardiothoracic surgeon-scientist Dr. Felix Fernandez that it will fund his RO1 application "National Longitudinal Outcomes Following Surgical Therapy for Lung Cancer." Dr. Fernandez is the PI of the grant on behalf of the Society of Thoracic Surgeons (STS). The study hopes to identify which patients are at risk for reduced long-term survival following lung cancer surgery and determine the most advantageous surgical strategies for these patients.

"It is well known that lung cancer is the leading cause of cancer mortality in the U.S.," says Dr. Fernandez. "However, the opportunity to lessen that trend is becoming more obtainable because detection of early stage lung cancer is becoming more common. This was demonstrated by recent efforts like the National Lung Screening Trial, which showed that screening heavy smokers with CT scans could reduce lung cancer mortality by 20%. Early detection will allow us to cure more lung cancers with surgery, though we need to understand which procedures will yield the best possibility of non-morbid cures for unique patient types and groups."

The source data for Dr. Fernandez's investigation will be provided by the linkage of the STS General Thoracic Surgery Database (GTSD) with administrative data collected by the Centers for Medicare and Medicaid Services (CMS). The STS-GTSD captures unique patient-level demographic, medical history, treatment, and complication details that are unavailable in other cancer databases, making it perfectly suited for large comparative effectiveness studies of lung cancer surgical strategies, though it is unable to give longitudinal survival data beyond 30 days. This limitation will be resolved by the CMS connection.

"By leveraging two complimentary national datasets to produce a unique cross-linked data infrastructure of individual patient clinical characteristics and longitudinal outcomes that cannot otherwise be replicated, we will identify predictors of long-term outcomes following lung cancer resection, including the optimal strategies with respect to surgical approach and extent of resection," says Dr. Fernandez.

Dr. Fernandez hypothesizes that long-term survival following lung cancer surgery will vary according to individual patient clinical and treatment variables, that such minimally invasive approaches as video assisted thoracic surgery (VATS) and sublobar resections are not inferior in terms of long-term survival compared to more invasive approaches like thoracotomy and lobectomy, and that VATS and sublobar resections are associated with more favorable economic outcomes than the standard methods. These hypotheses will be tested by creating a risk prediction model for long-term survival following lung cancer resection and comparing survival, resource use, and cost according to surgical approach and extent of pulmonary resection.

By establishing those patients at risk for poor long-term survival following lung cancer surgery as well as the most favorable surgical strategies for treating those patients and associated costs, the study results could allow physicians and patients to focus on individual patient characteristics and make better informed treatment decisions, drive quality improvement and value in lung cancer care both nationally and internationally, and guide the development of future prospective trials.
