Abstract
OBJECTIVE Evidence from the medical literature suggests that surgical trainees can benefit from mindful practices. Surgical educators are challenged with the need to address resident core competencies, some of which may be facilitated by higher levels of mindfulness. This study explores whether mindful residents perform better than their peers as members of the health care team. DESIGN This study employed a multiphase, multimethod design to assess resident mindfulness, communication, and clinical performance. SETTING Academic, tertiary medical center. PARTICIPANTS Residents (N = 51) working in an intensive care unit. In phase I, medical residents completed a self-report survey of mindfulness, communication, emotional affect, and clinical decision-making. In phase II, resident performance was assessed using independent ratings of mindfulness and clinical decision-making by attending physicians and registered nurses. RESULTS In phase 1, a significant positive relationship was found between resident performance and mindfulness, positive affect (PA), and communication. In phase 2, attending physicians/registered nurses' perceptions of residents' mindfulness were positively correlated with communication and inversely related to negative affect (NA). The top quartile of residents for performance and mindfulness had the lowest NA. Higher-rated residents underestimated their performance/mindfulness, whereas those in the lowest quartile overestimated these factors. CONCLUSIONS This study offers a number of implications for medical resident education. First, mindfulness was perceived to be a significant contributor to self-assessments of competency and performance. Second, both PA and NA were important to mindfulness and performance. Third, communication was associated with resident performance, mindfulness, and PA. These implications suggest that individual characteristics of mindfulness, communication, and affect, all potentially modifiable, influence care quality and safety. To improve low performers, surgical educators could screen and identify residents with inaccurate self-assessments. Residents open to feedback will improve faster and develop awareness toward situations and interactions with patients, colleagues, attending physicians, and staff.

Abstract
Nutrition support has become widely recognized as an essential component of optimal care for acutely ill patients. Enteral nutrition is preferred over parenteral routes when possible. However, prescribed enteral nutritional regimens are sometimes met with side effects and even complications. These adverse events have been collectively termed "intolerance," and forms of intolerance occur in a spectrum from bothersome at least to life threatening when most severe. Here we discuss nutritional access and its maintenance, introduce and define intolerance, and then review the current literature with regard to principal forms of enteral nutrition intolerance.

Abstract
The enteral route has become the standard of care to deliver nutrition support for hospitalized acute care and ambulatory care patients. The same access device is increasingly being used to deliver medications, which provides cost savings but also creates new challenges. Cost savings can be negated if the concomitant administration of nutrition elicits a decrease in bioavailability due to incompatibilities that alter drug or nutrition therapy. Feeding tubes can deliver nutrients and drugs to the stomach, small bowel, or both, with optimal efficacy of medications depending on delivery to the appropriate segment of the gastrointestinal tract. Liquid preparations are often the preferred formulation for enteral administration. Obstruction of the enteral access device may occur when specialized medication formulations are altered inappropriately. Occasionally, the enteral formula should be changed to modify the content of free water, fiber, electrolytes, or vitamins that may interfere with the drug therapy. Intolerance to enteral nutrition such as abdominal distention and diarrhea may be the result of the medication, and the causative agent should be identified to improve patient comfort. This article will address optimal drug delivery via enteral access devices and possible complications associated with therapy.

Abstract
Damage control surgery (DCS) was developed to manage exsanguinating trauma patients, but is increasingly applied to the management of peritoneal sepsis and abdominal catastrophes. Few manuscripts compare the outcomes of these surgeries on disparate patient populations. A multi-institutional three group propensity score matched case cohort study comparing penetrating trauma (PT-DCS), blunt trauma (BT-DCS), and intraperitoneal sepsis (IPS-DCS) was performed comparing patients treated with DSC between 2008 and 2013. Propensity scoring was performed using demographic and presenting physiologic data. Four hundred and twelve patients were treated with DCS across two institutions. Propensity matching for age, gender, and initial Acute Physiology and Chronic Health Evaluation II score 80 identified 80 patients per group for comparison. Rate of primary fascial closure was lowest in the IPS-DCS group, and highest in the penetrating trauma DCS group. Intra-abdominal complication rates were highest in the IPS-DCS group. IPS-DCS had increased time to definitive closure compared with the other two groups (RR 1.8; 1.3–2.2; P < 0.03). Mortality at 90 days was highest in the IPS-DCS group and patients whose definitive closure was delayed >eight days were more than twice the risk of death at 90 days across all groups. (RR 2.15; 1.2–3.5; P < 0.002). Expected outcomes after the use of DCS for trauma and emergency general surgery are quite different. Despite this difference, prompt abdominal closure at the earliest possible opportunity afforded the best outcome in patients managed via DCS.

Abstract
INTRODUCTION The purpose of this study is to determine whether discrepant patterns of horse-related trauma exist in mounted vs. unmounted equestrians from a single Level I trauma center to guide awareness of injury prevention. METHODS Retrospective data were collected from the University of Kentucky Trauma Registry for patients admitted with horse-related injuries between January 2003 and December 2007 (n=284). Injuries incurred while mounted were compared with those incurred while unmounted. RESULTS Of 284 patients, 145 (51%) subjects were male with an average age of 37.2 years (S.D. 17.2). Most injuries occurred due to falling off while riding (54%) or kick (22%), resulting in extremity fracture (33%) and head injury (27%). Mounted equestrians more commonly incurred injury to the chest and lower extremity while unmounted equestrians incurred injury to the face and abdomen. Head trauma frequency was equal between mounted and unmounted equestrians. There were 3 deaths, 2 of which were due to severe head injury from a kick. Helmet use was confirmed in only 12 cases (6%). CONCLUSION This evaluation of trauma in mounted vs. unmounted equestrians indicates different patterns of injury, contributing to the growing body of literature in this field. We find interaction with horses to be dangerous to both mounted and unmounted equestrians. Intervention with increased safety equipment practice should include helmet usage while on and off the horse.

Abstract
Dramatic increases in damage control and decompressive laparotomies and a significant increase in patients with open abdominal cavities have resulted in numerous techniques to facilitate fascial closure. We hypothesized addition of the abdominal reapproximation anchor system (ABRA) to the KCI Abdominal Wound Vac™ (VAC) or KCI ABThera™ would increase successful primary closure rates and reduce operative costs. Fourteen patients with open abdomens were prospectively randomized into a control group using VAC alone (control) or a study group using VAC plus ABRA (VAC-ABRA). All patients underwent regular VAC changes; patients receiving VAC-ABRA also underwent concomitant daily elastomer adjustment of the ABRA system. Primary end points included abdominal closure, number of operating room (OR) visits, and OR time use. Eight patients were included in the VAC-ABRA group and six patients in the control group. Primary closure rates between groups were not statistically different; however, the number of trips to the OR and OR time use were different. Despite higher Acute Physiology and Chronic Health Evaluation II scores, larger starting wound size, and higher rates of abdominal compartment syndrome, closure rates in the VAC-ABRA group were similar to VAC alone. Importantly, however, fewer OR trips and less OR time were required for the VAC-ABRA group.

Abstract
BACKGROUND The influence of in-house (IH) attendings on trauma patient survival and efficiency measures, such as emergency department length of stay (LOS), ICU LOS, and hospital LOS, has been debated for more than 20 years. No study has definitively shown improved outcomes with IH vs home-call attendings. This study examines trauma outcomes in a single, Level I trauma center before and after the institution of IH attending call. STUDY DESIGN Patient data were collected from the University of Kentucky's trauma registry. Based on the Trauma-Related Injury Severity Score, survival rates were compared between the IH and home-call groups. To evaluate efficiency, emergency department LOS, ICU LOS, and hospital LOS were compared. A separate subanalysis for the most severely injured patients (trauma alert red) was also performed. RESULTS The home-call group (n = 4,804) was younger (p = 0.018) and had a higher Injury Severity Score (p = 0.003) than the IH group (n = 5259), but there was no difference in Trauma-Related Injury Severity Score (p = 0.205) between groups. In-house attending presence did not reduce mortality. Emergency department LOS, ICU LOS, and hospital LOS were shorter during the IH period. Emergency department to operating room time was not different. There was no change in trauma alert red mortality with an attending present (20.7% vs 18.2%, p = 0.198). CONCLUSIONS In-house attending presence does not improve trauma patient survival. For the most severely injured patients, attendings presence does not reduce mortality. In-house coverage can improve hospital efficiency by decreasing emergency department LOS, hospital LOS, and ICU LOS.

Abstract
BACKGROUND Acute care surgery (ACS) includes trauma, surgical critical care, and emergent general surgery. There is a national shortage of institutions that can provide for patients needing access to emergency surgical care. Inability to fund ACS surgeons can be a barrier. We hypothesize that an ACS service, in an appropriately staffed hospital, generates a positive contribution margin (CM). STUDY DESIGN Fiscal data for 2009 were retrospectively reviewed at the University of Kentucky, a Level I trauma center with an ACS service. Contribution margin (ie, net revenue minus direct costs) and mean length of stay were calculated for all patients admitted to the ACS service. Inpatient data were stratified by trauma vs general surgery, emergent vs elective, and by payor mix. RESULTS Annual CM associated with the 5 ACS faculty was $21,799,000. Trauma generated higher CM than general surgery. General surgery had a greater CM, more if emergent than if elective ($9,500 vs $5,500; p < 0.01). Self-payment was lower with emergent general surgery vs trauma (20% vs 25%; p = 0.02). CONCLUSIONS Acute care surgery generates a positive CM. Emergent general surgery generates a greater CM than elective general surgery because of increased case mix index. These data suggest that hospital subsidization of acute care surgeons is financially feasible and might address the surgical workforce shortage and the critical problem of access to emergency surgical services.

Abstract
Introduction Tumor necrosis factor-alpha (TNF-α), an early mediator in the systemic inflammatory response to infection, is a potential therapeutic target in sepsis. The primary objective of this study was to determine the safety and tolerability of AZD9773, an ovine, polyclonal, anti-human TNF-α Fab preparation, in patients with severe sepsis. Secondary outcomes related to pharmacokinetic (PK) and pharmacodynamic (PD) parameters. Methods In this double-blind, placebo-controlled, multicenter Phase IIa study, patients were sequentially enrolled into five escalating-dose cohorts (single doses of 50 or 250 units/kg; multiple doses of 250 units/kg loading and 50 units/kg maintenance, 500 units/kg loading and 100 units/kg maintenance, or 750 units/kg loading and 250 units/kg maintenance). In each cohort, patients were randomized 2:1 to receive AZD9773 or placebo. Results Seventy patients received AZD9773 (n = 47) or placebo (n = 23). Baseline characteristics were similar across cohorts. Mean baseline APACHE score was 25.9. PK data demonstrated an approximately proportional increase in concentration with increasing dose and a terminal half-life of 20 hours. For the multiple-dose cohorts, serum TNF-α concentrations decreased to near-undetectable levels within two hours of commencing AZD9773 infusion. This suppression was maintained in most patients for the duration of treatment. AZD9773 was well tolerated. Most adverse events were of mild-to-moderate intensity and considered by the reporting investigator as unrelated to study treatment. Conclusions The safety, PK and PD data support the continued evaluation of AZD9773 in larger Phase IIb/III studies.

Abstract
Hypertension is common in hospitalized patients and there are many causes. Some patients have no prior history of hypertension, few symptoms, and no apparent morbidity related to acute rises in blood pressure. Though there is no established guideline for therapy in these cases, patients often receive therapy directed at the abnormal vital sign. It is hypothesized that this practice is common and the associated costs are significant. Using the inpatient pharmacy database at the University of Kentucky Chandler Medical Center, a verified Level I trauma center and quaternary referral center, patients on the emergency general surgery or orthopedic surgery services receiving intravenous hydralazine, metoprolol, or labetalol were identified. Subjects were analyzed for indications, parameters, associated history of hypertension, and direct costs. Over the 4-month study period, 114 subjects received 522 drug doses. More than half (55%) of subjects had a prior history of hypertension but only 75 per cent were started on their home medication. Of those without hypertension before admission, 18 per cent required therapy at discharge. Labetalol was the most frequently used agent and total pharmacy costs for this cohort of patients was over $1200. Pro re nata (PRN), short-acting antihypertensive therapy has little evidence base in asymptomatic patients, but its prevalence is high on surgical services. The cost is significant, especially when extrapolated to the larger hospital population at this single institution. Further research is warranted to determine the prevalence of this practice in other centers or national regions, as well as its cost and benefit.

Abstract
BACKGROUND/PURPOSE This study sought to establish objective anthropometric measures of fit or misfit for young riders on adult and youth-sized all-terrain vehicles and use these metrics to test the unproved historical reasoning that age alone is a sufficient measure of rider-ATV fit. METHODS Male children (6-11 years, n=8; and 12-15 years, n=11) were selected by convenience sampling. Rider-ATV fit was quantified by five measures adapted from published recommendations: (1) standing-seat clearance, (2) hand size, (3) foot vs. foot-brake position, (4) elbow angle, and (5) handlebar-to-knee distance. RESULTS Youths aged 12-15 years fit the adult-sized ATV better than the ATV Safety Institute recommended age-appropriate youth model (63% of subjects fit all 5 measures on adult-sized ATV vs. 20% on youth-sized ATV). Youths aged 6-11 years fit poorly on ATVs of both sizes (0% fit all 5 parameters on the adult-sized ATV vs 12% on the youth-sized ATV). CONCLUSIONS The ATV Safety Institute recommends rider-ATV fit according to age and engine displacement, but no objective data linking age or anthropometrics with ATV engine or frame size has been previously published. Age alone is a poor predictor of rider-ATV fit; the five metrics used offer an improvement compared to current recommendations.

Abstract
The most common and widely transplanted tissue world wide is blood, which in 2000 resulted in the transfusion of 12.5 million units of blood in the US alone [Goodnough LT, Shander A, Brecher ME. Transfusion medicine: looking to the future. Lancet 2003;361:161-9]. The current use of donated blood products is relatively safe; however, there are inherent problems with allogeneic blood transfusions. The wide spread use of blood in procedures results in problems involving inadequate supply exacerbated in times of war and disasters and by the limited storage life of blood donations (30-42 days). Blood contamination due to patient pre-disposition, poor collection, sterilization, or storage is the second most common cause of death from transfusion in the US [Hillyer CD, Josephson CD, Blajchman MA, Vostal JG, Epstein JS, Goodman JL. Bacterial contamination of blood components: risks, strategies, and regulation: joint ASH and AABB educational session in transfusion medicine. Hematology (Am Soc Hematol Educ Program) 2003:575-89]. Blood is a complex tissue involved in a plethora of homeostatic roles, including immunity, wound healing and the transport of nourishment, electrolytes, hormones, vitamins, heat, oxygen and the removal of metabolic waste products. However, by far the principle role of blood transfusions is the replacement of red cell volume and the maintenance of oxygen levels within the circulation. Creation of investigational new drugs (INDs) which would function as oxygen carriers and prolong shelf life is now a very active arena of scientific research. Several such IND products are now in clinical trials. This article gives an easy to follow concise evaluation of major areas of focus and current testing for each type of blood substitution molecule.

Abstract
• Background Language barriers are significant impediments to providing quality healthcare, and increased stress levels among nurses and physicians are associated with these barriers. However, little evidence supports the usefulness of a translation tool specific to healthcare.
• Objectives To evaluate the effectiveness of a novel English-Spanish translator designed specifically for nurses and physicians. The hypothesis was that the translator would be useful and that use of the translator would decrease stress levels among nurses and physicians caring for Spanish-speaking patients.
• Methods Novel English-Spanish translators were developed entirely on the basis of input from critical care nurses and physicians. After 7 months of use, users completed surveys. Usefulness of the translator and stress levels among users were reported.
• Results A total of 60% of nurses (n = 32) and 71% (n = 25) of physicians responded to the survey. A total of 96% of physicians and 97% of nurses considered the language barrier an impediment to delivering quality care. Nurses reported significantly more stress reduction than did physicians (P = .01). Most nurses and physicians had used the translator during the survey period. Overall, 91% of nurses and 72% of physicians found that the translator met their needs at the bedside some, most, or all of the time. All nurses thought that they most likely would use the translator in the future.
• Conclusions The translator was useful for most critical care nurses and physicians surveyed. Healthcare providers, especially nurses, experienced decreased stress levels when they used the translator.

Abstract
Blood is a precious and vital resource in medicine. Its importance in maintaining human life is second only to the oxygen it transports. Nearly 300,000 blood product transfusions occurred in Kentucky last year. While donor attrition from the pool is inevitable, recruiting efforts have resulted in an overall stable donor population in the state over the last five years. Roughly 5% of community members who are eligible to donate do so each year. Despite our effort to constantly recruit new donors, there is evidence to suggest that clinicians are less than rigorous in their efforts to conserve and to be accountable for this precious human product. For example, the indications for blood transfusions are often not documented in up to a third of the cases, and arbitrary transfusion "triggers" are often the criteria used to justify transfusion rather than the patient's clinical condition. Recent development of evidence-based criteria for prevention and treatment of anemia combined with technological advances suggest that a major paradigm shift in the clinical use of red cells is warranted.

Abstract
BACKGROUND Arginine has been added to immune enhancing diets that may improve patient outcomes, but little is known about the metabolic fate of supplemental arginine. We hypothesize that supplemental enteral arginine in injured patients is metabolized to ornithine by increased activity of the enzyme arginase. MATERIALS AND METHODS Twenty-five adult patients with injury severity scores > or =20 received up to 14 days of enteral nutrition supplemented with arginine (30 g/day) or placebo in a prospective, randomized, blinded study. Plasma arginine, citrulline, and ornithine concentrations and peripheral blood mononuclear cell (PBMC) arginase activity were measured at baseline and on days 1, 3, 5, 7, 10, and 14. Clinical data collected included demographics, injury patterns, lengths of stay, and infectious complications. Data were analyzed using ANOVA and t test. RESULTS PBMC arginase activity was elevated in all patients. In the supplemented group, plasma arginine concentrations increased at days 7, 10, and 14 when compared to baseline (P < 0.05) and were higher at day 14 when compared to those of controls (P < 0.05). Citrulline concentrations in both groups were unchanged over time. Ornithine concentration increased within 24 h of arginine supplementation and remained elevated when compared to baseline (P < 0.01). Ornithine concentration in the supplemented group was higher at days 1, 3, 5, and 7 when compared to that of controls (P < 0.05). There were no differences in clinical outcomes. CONCLUSIONS Supplemental enteral arginine is absorbed in injured patients and increases arginine levels. Supplemental arginine appears to be metabolized to ornithine. Increased arginase enzyme activity in peripheral blood mononuclear cells may be a contributor.

Abstract
Appendicitis and pregnancy are both common conditions, and when they co-exist, both the general surgeon and obstetrician are presented with unique challenges. Acute appendicitis is the most common cause of the acute abdomen during pregnancy, effecting 0.1–0.3 per cent of pregnancies each year. With an estimated 4 million deliveries per year in the United States, there are potentially as many as 12,000 cases of acute appendicitis to be managed by the general surgeon during pregnancy (Eur J Surg 1992;158:603–6; Curr Surg 2003;60:164–73). Laparoscopic appendectomy has become a routine procedure and is now widely performed in North America. Although laparoscopic appendectomy has been discussed during pregnancy, limited data is available on the role of laparoscopic appendectomy in the third trimester of pregnancy. In fact, some authors have advocated a gestational age of 26–28 weeks to be the upper gestational limit for successful completion of laparoscopic surgery (Obstet Gynecol Surg 2001;56:50–9). In this paper, we present two recent cases of successful laparoscopic appendectomy during late pregnancy without immediate complication to mother or fetus and a description of our operative technique.
