Interaction of Insurance and Neighborhood Income on Operative Colorectal Cancer Outcomes Within a National Database.

INTRODUCTION: Sociodemographic disparities in colorectal cancer (CRC) surgical patients are known. Few studies, however, have examined the intersection of insurance type and median household income (MHI). METHODS: In this retrospective analysis of the National Inpatient Sample from 2000 to 2019, all CRC surgery patients between 50 and 64 y old were included. Patients were further stratified based on insurance type (commercial, Medicaid, and uninsured) as well as county-level MHI quartiles. Outcomes included nonelective surgery (primary outcome), inpatient mortality, complications, and blood transfusions. Multivariate logistic regression adjusted for sociodemographic variables, medical comorbidities, and hospital-level factors. RESULTS: Of 108,606 patients, 80.5% of patients had commercial insurance, while 5.8% were uninsured. On multivariate analysis, Medicaid or no insurance, especially when living in a lower-income community, were associated with significantly higher odds of nonelective surgery (ORs: 1.11-4.54). There was a stepwise effect on nonelective surgery by insurance type (uninsured with lower odds than insured) and MHI (each lower quartile had higher odds). There were similar trends for inpatient blood transfusions, but there were no significant differences in mortality or complications. CONCLUSIONS: Especially when considered together, noncommercial insurance and lower MHI were associated with worse outcomes in CRC patients. Insurance was more protective than MHI against worse outcomes. These findings among a screening-aged cohort have policy planning implications for insurance expansions and healthcare funding allocations. Further research is needed to understand the complex underlying mechanisms that create this interaction between insurance and MHI.

Use of a New Prevention Model in Acute Care Surgery: A Population Approach to Preventing Emergency Surgical Morbidity and Mortality.

Whether patients undergo the more morbid and costly emergent rather than an elective type of surgery, may depend on many factors. Since tertiary prevention (preventing poor outcomes from emergency surgery) carries a much higher mortality than secondary prevention (preventing emergency surgery) or primary prevention (preventing the disease requiring surgery), the overall United States mortality might be reduced significantly, if emergency surgery could be avoided via high-quality primary prevention and non-surgical therapy or increasing elective surgery at the expense of emergency procedures, e.g., secondary prevention. The practice and study of acute care surgery then has the potential to broaden from a focus on the patient in the hospital emergency and operating rooms to the patient who no longer requires either, whose disease is treated or prevented in his/her/their community.

Validation of the American Association for the Surgery of Trauma Emergency General Surgery Grading System for Colorectal Resection: An EAST Multicenter Study.

BACKGROUND: The American Association for the Surgery of Trauma (AAST) has developed a grading system for emergency general surgery (EGS) conditions. We sought to validate the AAST EGS grades for patients undergoing urgent/emergent colorectal resection. METHODS: Patients enrolled in the "Eastern Association for the Surgery of Trauma Multicenter Colorectal Resection in EGS-to anastomose or not to anastomose" study undergoing urgent/emergent surgery for obstruction, ischemia, or diverticulitis were included. Baseline demographics, comorbidity severity as defined by Charlson comorbidity index (CCI), procedure type, and AAST grade were prospectively collected. Outcomes included length of stay (LOS) in-hospital mortality, and surgical complications (superficial/deep/organ-space surgical site infection, anastomotic leak, stoma complication, fascial dehiscence, and need for further intervention). Multivariable logistic regression models were used to describe outcomes and risk factors for surgical complication or mortality. RESULTS: There were 367 patients, with a mean (± SD) age of 62 ± 15 years. 39% were women. The median interquartile range (IQR) CCI was 4 (2-6). Overall, the pathologies encompassed the following AAST EGS grades: I (17, 5%), II (54, 15%), III (115, 31%), IV (95, 26%), and V (86, 23%). Management included laparoscopic (24, 7%), open (319, 87%), and laparoscopy converted to laparotomy (24, 6%). Higher AAST grade was associated with laparotomy (P = .01). The median LOS was 13 days (8-22). At least 1 surgical complication occurred in 33% of patients and the mortality rate was 14%. Development of at least 1 surgical complication, need for unplanned intervention, mortality, and increased LOS were associated with increasing AAST severity grade. On multivariable analysis, factors predictive of in-hospital mortality included AAST organ grade, CCI, and preoperative vasopressor use (odds ratio (OR) 1.9, 1.6, 3.1, respectively). The American Association for the Surgery of Trauma emergency general surgery grade was also associated with the development of at least 1 surgical complication (OR 2.5), while CCI, preoperative vasopressor use, respiratory failure, and pneumoperitoneum were not. CONCLUSION: The American Association for the Surgery of Trauma emergency general surgery grading systems display construct validity for mortality and surgical complications after urgent/emergent colorectal resection. These results support incorporation of AAST EGS grades for quality benchmarking and surgical outcomes research.

Emergency surgery workforce and its inverse relationship with multidimensional poverty in Colombia.

PURPOSE: General surgeons, anesthesiologists, obstetricians and gynecologists (ob-gyns), and orthopedic surgeons are the vital disciplines to provide emergency surgery within a healthcare system. This paper aims to examine the relationship (if any) between multidimensional poverty (MDP) and GDP per-capita with the emergency surgery workforce density in Colombia. METHODS: We performed an ecological study, where the observation units were the 32 Colombian departments. The total numbers of general surgeons, anesthesiologists, ob-gyns, and orthopedic surgeons were obtained from the "Registro Unico Nacional de Talento Humano en Salud" (ReTHUS) registry. The 2020 population projections, the incidence of MDP and the GDP per capita were obtained from the Colombian National Administrative Department of Statistics. A spearman's correlation coefficient was calculated to measure the strength of the correlations between the surgical workforce density with MDP and GDP per-capita. RESULTS: There were significant moderate inverse linear correlations between the incidence of multidimensional poverty and workforce density. The correlation coefficients for the incidence of multidimensional poverty and the workforce density were - 0.5273, - 0.5620, - 0.4704, and - 0.4612 for surgeons, anesthesiologists, ob-gyns, and orthopedic surgeons, respectively. Conversely, the correlation coefficients for the GDP per-capita and the workforce density were 0.4045, 0.3822, 0.4404, and 0.3742 for surgeons, anesthesiologists, ob-gyns, and orthopedic surgeons, respectively. CONCLUSION: This study found that Colombian trauma and emergency surgery workforce density was inversely and directly correlated with multidimensional poverty and GDP per-capita levels, respectively. The relationship of these economic indicators with the surgical capacity deserves further investigation.

Access to paediatric cardiac surgery in Colombia: a population-based study.

OBJECTIVES: Globally congenital heart disease mortality is declining, yet the proportion of infant deaths attributable to heart disease rises in Colombia and other middle-sociodemographic countries. We aimed to assess the accessibility of paediatric cardiac surgery (PCS) to children <18 years of age in 2016 in the South American country of Colombia. METHODS: In Bogotá, Colombia, a multi-national team used cross-sectional and retrospective cohort study designs to adapt and evaluate 4 health system indicators at the national level: first, the population with timely geographic access to an institution providing PCS; second, the number of paediatric cardiac surgeons; third, this specialized procedure volume and its national distribution; and fourth, the 30-day perioperative mortality rate after PCS in Colombia. RESULTS: Geospatial mapping approximates 64% (n = 9 894 356) of the under-18 Colombian population lives within 2-h drivetime of an institution providing PCS. Twenty-eight cardiovascular surgeons report performing PCS, 82% (n = 23) with formal training. In 2016, 1281 PCS procedures were registered, 90% of whom were performed in 6 of the country's 32 departments. National non-risk-adjusted all-cause 30-day perioperative mortality rate after PCS was 2.73% (n = 35). CONCLUSIONS: Colombia's paediatric population had variable access to cardiac surgery in 2016, largely dependent upon geography. While the country may have the capacity to provide timely, high-quality care to those who need it, our study enables future comparative analyses to measure the impact of health system interventions facilitating healthcare equity for the underserved populations across Colombia and the Latin American region.

Use of geospatial analysis for priority setting in surgical system investment in Guatemala.

Background: Two-hour and 30 min travel times to a hospital capable of performing emergency general surgery and cesarean section are benchmarks for timely surgical access. This study aimed to estimate the population of Guatemala with timely access to surgical care and identify existing hospitals where the expansion of surgical services would increase access. Methods: The World Federation of Societies of Anaesthesiologists (WFSA) Anesthesia Facility Assessment Tool (AFAT) previously identified 37 public Guatemalan hospitals that provide surgical care. Nine additional public non-surgical hospitals were also identified. Geospatial analysis was performed to estimate walking and driving geographic access to all 46 hospitals. We calculated the potential increase in access that would accompany the expansion of surgical services at each of the nine non-surgical hospitals. Findings: The percentage of the population with walking access to a surgical hospital within 30 min, 1 h, and 2 h are 5·1%, 12·9%, and 27·3%, respectively. The percentage of people within 30 min, 1 h, and 2 h driving times are 27·3%, 41·1%, and 53·1%, respectively. The median percentage of the population within each of Guatemala's 22 administrative departments with 2 h walking access was 19·0% [IQR 14·1-30·7] and 2 h driving access was 52·4% [IQR 30·5-62·8]. Expansion of surgical care at existing public Guatemalan hospitals in Guatemala would result in a minimal increase in overall geographic access compared to current availability. Interpretation: While Guatemala provides universal health coverage, geographic access to surgical care remains inadequate. Geospatial mapping and survey data work synergistically to assess surgical system strength and identify gaps in geographic access to essential surgical care. Funding: None.

Non-English Primary Language is Associated with Emergency Surgery for Diverticulitis.

BACKGROUND: Language barriers can limit access to care for patients with a non-English primary language (NEPL). The objective of this study was to define the association between primary language and emergency versus elective surgery among diverticulitis patients. MATERIALS AND METHODS: Retrospective cohort study of adult patients from the 2009-2014 New Jersey State Inpatient Database. Patients were included if they had primary language data and underwent a partial colon resection for diverticulitis. Primary language was dichotomized into NEPL versus English primary language (EPL). The primary outcome was surgical admission type - urgent/emergent (referred to as "emergency") versus elective. Descriptive and multivariable analyses were performed. RESULTS: A total of 9,453 patients underwent surgery for diverticulitis, of which 592 (6.3%) had NEPL. Among NEPL patients, 300 (51%) had Spanish as primary language and 292 (49%) had another non-Spanish primary language. Patients with NEPL and EPL were similar in age (median age 58 versus 59 years; P = 0.54) and sex (52% versus 53% female; P = 0.45). Patients with NEPL were less likely to have commercial insurance (45% versus 59%; P <0.001). On multivariable analysis, compared to patients with EPL, NEPL was associated with increased odds of emergency surgery for diverticulitis (OR 1.35; 95% Confidence Interval 1.13-1.62; P = 0.001) CONCLUSION: Patients with NEPL have higher odds of emergency versus elective surgery for diverticulitis compared to patients with EPL. Further research is needed to examine differences in referral pathways, patient-provider communication, and health literacy that may hinder access to elective surgery in patients with diverticulitis.

A longitudinal surgical systems strengthening research program for medical students: the exploration of a model for global health education.

BACKGROUND: In response to the staggering global burden of conditions requiring emergency and essential surgery, the development of international surgical system strengthening (SSS) is fundamental to achieving universal, timely, quality, and affordable surgical care. Opportunity exists in identifying optimal collaborative processes that both promote global surgery research and SSS, and include medical students. This study explores an education model to engage students in academic global surgery and SSS via institutional support for longitudinal research. OBJECTIVES: We set out to design a program to align global health education and longitudinal health systems research by creating an education model to engage medical students in academic global surgery and SSS. PROGRAM DESIGN AND IMPLEMENTATION: In 2015, medical schools in the United States and Colombia initiated a collaborative partnership for academic global surgery research and SSS. This included development of two longitudinal academic tracks in global health medical education and academic global surgery, which we differentiated by level of institutional resourcing. Herein is a retrospective evaluation of the first two years of this program by using commonly recognized academic output metrics. MAIN ACHIEVEMENTS: In the first two years of the program, there were 76 total applicants to the two longitudinal tracks. Six of the 16 (37.5%) accepted students selected global surgery faculty as mentors (Acute Care Surgery faculty participating in SSS with Colombia). These global surgery students subsequently spent 24 total working weeks abroad over the two-year period participating in culminating research experiences in SSS. As a quantitative measure of the program's success, the students collectively produced a total of twenty scholarly pieces in the form of accepted posters, abstracts, podium presentations, and manuscripts in partnership with Colombian research mentors. POLICY IMPLICATIONS: The establishment of scholarly global health education and research tracks has afforded our medical students an active role in international SSS through participation in academic global surgery research. We propose that these complementary programs can serve as a model for disseminated education and training of the future global systems-aware surgeon workforce with bidirectional growth in south and north regions with traditionally under-resourced SSS training programs.

Assessment of Cervical Cancer Prevention and Treatment Infrastructure in Belize.

PURPOSE: Belize has one of the highest cervical cancer burdens among Latin American and Caribbean countries, despite the implementation of national policies to increase access to prevention and treatment services. This study evaluates the policies, infrastructure, and workforce of the cervical cancer management system in Belize to inform capacity building efforts. METHODS: In 2018, health facility assessments were conducted across all six districts of Belize at the national pathology facility and 12 public facilities identified as critical to cervical cancer control. Human and infrastructure resource availability and existing policies related to cervical cancer screening and treatment services were assessed through a structured instrument. RESULTS: The public cervical cancer screening workforce in Belize consists of 75 primary care nurses and physicians-one per 1,076 screening-eligible women, with 44% conducting rural outreach. All districts have at least one screening facility, but 50% perform screening services only once per week. Colposcopy and loop electrical excision procedures are available in three and four districts, respectively; radical hysterectomy and chemotherapy are available in two districts; and radiation therapy is unavailable. Of essential pathology equipment, 38.5% were present and functional, 23% were present but nonfunctional, and 38.5% were unavailable. Additionally, 35% of supplies were unavailable at the time of assessment, and 75% were unavailable at least once in the 12 months before assessment. CONCLUSION: Public-sector cervical cancer management services differ among districts of Belize, with tertiary service availability concentrated in the largest district. Screening, outreach, and pathology are limited mostly by resource availability. This study characterizes the current capacity of services in Belize and pinpoints health system components for future investment and capacity-building efforts.

Differences in outcomes after emergency general surgery between Hispanic subgroups in the New Jersey State Inpatient Database (2009-2014): The Hispanic population is not monolithic.

BACKGROUND: Our aim was to examine differences in clinical outcomes between Hispanic subgroups who underwent emergency general surgery (EGS). METHODS: Retrospective cohort study of the HCUP State Inpatient Database from New Jersey (2009-2014), including Hispanic and non-Hispanic White (NHW) adult patients who underwent EGS. Multivariable analyses were performed on outcomes including 7-day readmission and length of stay (LOS). RESULTS: 125,874 patients underwent EGS operations. 22,971 were Hispanic (15,488 with subgroup defined: 7,331 - Central/South American; 4,254 - Puerto Rican; 3,170 - Mexican; 733 - Cuban). On multivariable analysis, patients in the Central/South American subgroup were more likely to be readmitted compared to the Mexican subgroup (OR 2.02; p < 0.001, respectively). Puerto Rican and Central/South American subgroups had significantly shorter LOS than Mexican patients (Puerto Rico -0.58 days; p < 0.001; Central/South American -0.30 days; p = 0.016). CONCLUSIONS: There are significant differences in EGS outcomes between Hispanic subgroups. These differences could be missed when data are aggregated at Hispanic ethnicity.

Mesenteric venous thrombosis: A lethal complication of hyperglycemic crises.

PURPOSE: Although hyperglycemic crises can lead to a hypercoagulable state, few instances of associated mesenteric venous thrombosis (MVT) have been reported. Worsening abdominal pain in the context of shock requiring vasopressor support should prompt urgent further investigation. SUMMARY: A 44-year-old Hispanic male arrived at an emergency department with chief complaints of lethargy, polydipsia, and polyuria. His past medical history included type 2 diabetes, epilepsy, obesity, tobacco smoking, and noncompliance with his medications. On arrival the patient had a serum glucose concentration of >1,600 mg/dL, and hyperosmolar hyperglycemic syndrome (HHS) was diagnosed. The patient was admitted to the intensive care unit with respiratory failure and subsequently developed shock refractory to fluid resuscitation, necessitating vasopressor support. On hospital day 4, a computerized tomogram obtained for investigation of increasing abdominal tenderness revealed superior MVT and pneumatosis intestinalis. Despite an emergency laparotomy and enterectomy, the patient ultimately succumbed on hospital day 41 due to recurrent pneumonia complicated by acute respiratory distress syndrome and septic shock. CONCLUSION: Shock that is refractory to aggressive fluid resuscitation, necessitating pressor support, in the setting of HHS or diabetic ketoacidosis should prompt investigation for the underlying source of shock. Other etiologies, including hypovolemic, cardiogenic, and obstructive shock, should be considered; however, infection is the leading trigger of hyperglycemic crises. Although rarely reported, MVT should be considered in the diagnostic algorithm in the absence of an identified infectious source. Prompt investigation should include use of diagnostic modalities such as computed tomography to assess for MVT.

Colorectal resection in emergency general surgery: An EAST multicenter trial.

OBJECTIVE: Evidence comparing stoma creation (STM) versus anastomosis after urgent or emergent colorectal resection is limited. This study examined outcomes after colorectal resection in emergency general surgery patients. METHODS: This was an Eastern Association for the Surgery of Trauma-sponsored prospective observational multicenter study of patients undergoing urgent/emergent colorectal resection. Twenty-one centers enrolled patients for 11 months. Preoperative, intraoperative, and postoperative variables were recorded. χ, Mann-Whitney U test, and multivariable logistic regression models were used to describe outcomes and risk factors for surgical complication/mortality. RESULTS: A total of 439 patients were enrolled (ANST, 184; STM, 255). The median (interquartile range) age was 62 (53-71) years, and the median Charlson Comorbidity Index (CCI) was 4 (1-6). The most common indication for surgery was diverticulitis (28%). Stoma group was older (64 vs. 58 years, p < 0.001), had a higher CCI, and were more likely to be immunosuppressed. Preoperatively, STM patients were more likely to be intubated (57 vs. 15, p < 0.001), on vasopressors (61 vs. 13, p < 0.001), have pneumoperitoneum (131 vs. 41, p < 0.001) or fecal contamination (114 vs. 33, p < 0.001), and had a higher incidence of elevated lactate (149 vs. 67, p < 0.001). Overall mortality was 13%, which was higher in STM patients (18% vs. 8%, p = 0.02). Surgical complications were more common in STM patients (35% vs. 25%, p = 0.02). On multivariable analysis, management with an open abdomen, intraoperative blood transfusion, and larger hospital size were associated with development of a surgical complication, while CCI, preoperative vasopressor use, steroid use, open abdomen, and intraoperative blood transfusion were independently associated with mortality. CONCLUSION: This study highlights a tendency to perform fecal diversion in patients who are acutely ill at presentation. There is a higher morbidity and mortality rate in STM patients. Independent predictors of mortality include CCI, preoperative vasopressor use, steroid use, open abdomen, and intraoperative blood transfusion. Following adjustment by clinical factors, method of colon management was not associated with surgical complications or mortality. LEVEL OF EVIDENCE: Therapeutic study, level IV.

Integrating a Novel Global Surgery and Health Inequity Course to the Surgical Clerkship.

OBJECTIVE: Medical students report growing interest in health inequity and global surgery, subjects not currently integrated to their core curriculum. Currently, fundamental tenets of global surgical inequity are only available to students on an elective basis or in special interest groups. Therefore, an hour-long course with emphasis on global surgery was developed for third-year medical students. The aim of this study was to examine student response to this pilot course and to establish whether course content was applicable to clinical rotations. DESIGN: A 1-hour structured curriculum was delivered to third-year medical students (MS3s) during the 2-day orientation phase of each rotation of an 8-week surgery clerkship from August 2018 to May 2019. The course targeted approximately 30 students per session in the preclinical orientation at Rutgers-New Jersey Medical School. Upon completion of the 8-week clerkship rotation, a paper survey was administered to evaluate student's exposure to previous content, attitudes toward global health, interest and engagement in course materials, and applicability of learned course content to local environments. SETTING: Rutgers-New Jersey Medical School, an urban medical school located in Newark, New Jersey. PARTICIPANTS: A total of 191 students attended the global surgery and health equity course; 146 participants participated in the postcourse survey. RESULTS: When asked about baseline interest in global or public health, the majority (51%) were extremely interested or very interested. Nearly all participants found the course to be valuable (94%). When asked which educational modality was preferred, 23% of participants favored the traditional lecture component and 29% favored case-based discussions. Nearly half (48%) the respondents found both modalities to be valuable. Fifty students (34% of respondents) reported encounters with patients affected by barriers in access to surgical care during their clerkships. CONCLUSIONS: Medical students responded favorably to this health inequity and global surgery pilot course and requested supplemental lectures. Additionally, course content was applicable to local clinical experiences. Therefore, 1 modality of integrating global surgery to the established curriculum is under the framework of health inequity and social determinants of health during surgical clerkships. This study demonstrates that meaningful inclusion of global surgery and health inequity can be implemented within the existing curricular structure.

Use of the six core surgical indicators from the Lancet Commission on Global Surgery in Colombia: a situational analysis.

BACKGROUND: Surgical, anaesthetic, and obstetric (SAO) health-care system strengthening is needed to address the emergency and essential surgical care that approximately 5 billion individuals lack globally. To our knowledge, a complete, non-modelled national situational analysis based on the Lancet Commission on Global Surgery surgical indicators has not been done. We aimed to undertake a complete situation analysis of SAO system preparedness, service delivery, and financial risk protection using the core surgical indicators proposed by the Commission in Colombia, an upper-middle-income country. METHODS: Data to inform the six core surgical system indicators were abstracted from the Colombian national health information system and the most recent national health survey done in 2007. Geographical access to a Bellwether hospital (defined as a hospital capable of providing essential and emergency surgery) within 2 h was assessed by determining 2 h drive time boundaries around Bellwether facilities and the population within and outside these boundaries. Physical 2 h access to a Bellwether was determined by the presence of a motor vehicle suitable for individual transportation. The Department Administrativo Nacional de Estadística population projection for 2016 and 2018 was used to calculate the SAO provider density. Total operative volume was calculated for 2016 and expressed nationally per 100 000 population. The total number of postoperative deaths that occurred within 30 days of a procedure was divided by the total operative volume to calculate the all-cause, non-risk-adjusted postoperative mortality. The proportion of the population subject to impoverishing costs was calculated by subtracting the baseline number of impoverished individuals from those who fell below the poverty line once out-of-pocket payments were accounted for. Individuals who incurred out-of-pocket payments that were more than 10% of their annual household income were considered to have experienced catastrophic expenditure. Using GIS mapping, SAO system preparedness, service delivery, and cost protection were also contextualised by socioeconomic status. FINDINGS: In 2016, at least 7·1 million people (15·1% of the population) in Colombia did not have geographical access to SAO services within a 2 h driving distance. SAO provider density falls short of the Commission's minimum target of 20 providers per 100 000 population, at an estimated density of 13·7 essential SAO health-care providers per 100 000 population in 2018. Lower socioeconomic status of a municipality, as indicated by proportion of people enrolled in the subsidised insurance regime, was associated with a smaller proportion of the population in the municipality being within 2 h of a Bellwether facility, and the most socioeconomically disadvantaged municipalities often had no SAO providers. Furthermore, Colombian providers appear to be working at or beyond capacity, doing 2690-3090 procedures per 100 000 population annually, but they have maintained a relatively low median postoperative mortality of 0·74% (IQR 0·48-0·84). Finally, out-of-pocket expenses for indirect health-care costs were a key barrier to accessing surgical care, prompting 3·1 million (6·4% of the population) individuals to become impoverished and 9·5 million (19·4% of the population) individuals to incur catastrophic expenditures in 2007. INTERPRETATION: We did a non-modelled, indicator-based situation analysis of the Colombian SAO system, finding that it has not yet met, but is working towards achieving, the targets set by the Lancet Commission on Global Surgery. The observed interdependence of these indicators and correlation with socioeconomic status are consistent with well recognised factors and outcomes of social, health, and health-care inequity. The internal consistency observed in Colombia's situation analysis validates the use of the indicators and has now informed development of an early national SAO plan in Colombia, to set a data-informed stage for implementation and evaluation of timely, safe, and affordable SAO health care, within the National Public Health Decennial Plan, which is due in 2022.

Comparison of Common Analytical Methods for the Quantification of Total Polyphenols and Flavanols in Fruit Juices and Ciders.

Multiple analytical methods are used for quantification of total polyphenols and total flavanols in fruit juices and beverages. Four methods were evaluated in this study: Folin-Ciocalteu (F-C), Lowenthal permanganate (L-P), 4-dimethylaminocinnamaldehyde (DMAC), and the bovine serum albumin (BSA) precipitation method. Method validation parameters, including working range, limit of detection, limit of quantitation, precision (repeatability), accuracy, and specificity, were assessed and compared. The F-C method was not specific to polyphenols, and the L-P method had the widest working range but lacked accuracy. The DMAC method was the most specific to flavanols, and the BSA method was not suitable for quantification of smaller flavanols, such as catechin and epicatechin. Quantitative performance was evaluated using commercial fruit juice samples (n = 14), apple juice samples of different cultivars (n = 22), and commercial ciders (n = 17). In general, the L-P titration method and DMAC method resulted in higher quantitative values than the F-C method and BSA precipitation method, respectively. However, ratios of results obtained by the L-P and F-C method ranged from 1 to 28, and ratios of results obtained by the DMAC and BSA precipitation method ranged from <1 to 280. This tremendous variation is likely due to variation in polyphenol composition and sample matrix. This information provides perspective for comparison of results obtained through these different methods, and a basis for choosing the most appropriate analytical method for quantification of polyphenols to address a specific research question when working with commercial fruit juice, apple juice from different apple cultivars, and commercial ciders. PRACTICAL APPLICATION: This study compared results obtained when four common polyphenol quantification methods were applied to a diverse selection of fruit juices and beverages with distinct polyphenol composition and sample matrix. The matrix and polyphenol composition of the samples significantly influenced the results. Our findings can help manufacturers of fruit-based products choose the most appropriate analytical method for polyphenol quantification as part of a quality assurance program or to convey information on dietary polyphenol content to consumers. An assessment of analytical method validation parameters is provided for each of the four methods, which will help users of these methods to understand their limitations.

Next Generation of Global Surgeons: Aligning Interest With Early Access to Global Surgery Education.

BACKGROUND: Although interest in global surgery is increasing among medical students,1 several questions remain unanswered such as: the association of demographics with said interest, the extent that global surgical burden education has been integrated into medical education, and the availability of global surgery electives. This study aimed to assess the current state of global surgery education in the United States (U.S.) to support recommendations for future curriculum development. MATERIALS AND METHODS: An anonymous online survey was distributed to medical students currently enrolled in the U.S. Descriptive data were compiled regarding interest in and access to global surgery programs; demographic data were analyzed using chi-squared testing for categorical variables. RESULTS: A total of 754 students from 18 medical schools throughout the U.S. responded to the survey. Only complete responses were included in final analysis (n = 658). Most of the respondents (66%) reported interest in global surgery, with a higher proportion of those interested being in their preclinical years. However, the majority (79%) reported that global surgery issues are rarely or never addressed in their required curriculum. Over half of respondents were unaware of whether their school even offers such programs. CONCLUSIONS: Although interest in global surgery is on the rise among medical students, results suggest that many currently lack exposure to global surgery concepts in their medical education. To that end, early exposure may be most effective during the preclinical years, so that the next generation may align global surgery participation with clinical aspirations, with the ultimate goal of addressing global disparities.

Management of duodenal trauma: A retrospective review from the Panamerican Trauma Society.

INTRODUCTION: The operative management of duodenal trauma remains controversial. Our hypothesis is that a simplified operative approach could lead to better outcomes. METHODS: We conducted an international multicenter study, involving 13 centers. We performed a retrospective review from January 2007 to December of 2016. Data on demographics, mechanism of trauma, blood loss, operative time, and associated injured organs were collected. Outcomes included postoperative intra-abdominal sepsis, leak, need for unplanned surgery, length of stay, renal failure, and mortality. We used the Research Electronic Data Capture tool to store the data. Poisson regression using a backward selection method was used to identify independent predictors of mortality. RESULTS: We collected data of 372 patients with duodenal injuries. Although the duodenal trauma was complex (median Injury Severity Score [ISS], 18 [interquartile range, 2-3]; Abbreviated Injury Scale, 3.5 [3-4]; American Association for the Surgery of Trauma grade, 3 [2-3]), primary repair alone was the most common type of operative management (80%, n = 299). Overall mortality was 24%. On univariate analysis, mortality was associated with male gender, lower admission systolic blood pressure, need for transfusion before operative repair, higher intraoperative blood loss, longer operative time, renal failure requiring renal replacement therapy, higher ISS, and associated pancreatic injury. Poisson regression showed higher ISS, associated pancreatic injury, postoperative renal failure requiring renal replacement therapy, the need for preoperative transfusion, and male gender remained significant predictors of mortality. Duodenal suture line leak was statistically significantly lower, and patients had primary repair over every American Association for the Surgery of Trauma grade of injury. CONCLUSIONS: The need for transfusion prior to the operating room, associated pancreatic injuries, and postoperative renal failure are predictors of mortality for patients with duodenal injuries. Primary repair alone is a common and safe operative repair even for complex injuries when feasible. LEVEL OF EVIDENCE: Therapeutic study, level IV.
