Abstract
INTRODUCTION Surgical societies provide a plethora of resources for trainees; however, these opportunities are often underused due to suboptimal guidance, sponsorship, or mentorship. Here, we present the Society of Asian Academic Surgeons (SAAS) experience in enhancing the trainee experience and engagement in a surgical society focused on professional development. MATERIALS AND METHODS We conducted an interactive idea-generating session during the 2022 SAAS Conference with all Associate Members (trainees) present in Honolulu, HI. Recurrent themes, concepts, and ideas/suggestions were carefully considered when planning the next SAAS Conference in Baltimore, MD. We employed a more targeted approach to trainee engagement at the 2023 SAAS Conference, with breakout sessions geared toward various levels of trainees, in addition to increased social events and networking opportunities. We obtained feedback from trainees in attendance through an electronic survey and informal conversations with faculty and Associate Members. RESULTS Opportunities for surgical subspecialty networking was the most well-received portion of our formal Career Development program. The majority of trainees in attendance were medical students or junior residents who valued the exposure to junior faculty and those in leadership positions at academic institutions. The addition of a group text for easy communication among trainees and informal social activities for Associate Member networking among themselves were crucial in improving the overall conference experience. CONCLUSIONS Opportunities to maximize trainee engagement in surgical societies are heightened during in-person conferences. Targeted session topics, guided networking opportunities, and creating channels for easier communication along with more social events have enhanced the overall experience for aspiring and current surgical trainees.

Abstract
BACKGROUND Liver transplant recipients with persistent renal dysfunction may be prioritized on the kidney transplant waitlist based on the Organ Procurement and Transplantation Network "safety-net" policy implemented in 2017. The aim of this study was to evaluate the utilization of kidney transplant and posttransplant outcomes, of liver transplant recipients with persistent renal dysfunction before and after implementation of the Organ Procurement and Transplantation Network kidney safety-net policy and standardization of simultaneous liver-kidney requirements. METHODS Using the United Network for Organ Sharing database from January 2015 to March 2019, outcomes of liver transplant recipients listed for kidney transplant and the subset who received kidney after liver transplants were compared before and after policy implementation. RESULTS Liver transplant recipients listed for kidney transplant increased from 58 to 200, and kidney after liver transplants increased from 29.3% to 42.5% after safety-net policy implementation. Post-policy kidney after liver transplants received more local organs (91.8% vs 70.6%, P = .03) and trended toward shorter waitlist time (47 [17-123] vs 84 [37-226] days, P = .051). The pre- and post-policy cohorts had similar (P > .05) kidney donor profile index (0.43 [0.27-0.69] vs 0.42 [0.28-0.58]) and delayed graft function (11.8% vs 14.1%). Patient, kidney graft, and liver graft survival were similar (P > .05) between pre and post-policy cohorts. Patient and kidney graft survival were similar between kidney after liver transplants and propensity score-matched kidney transplant alone recipients. Patient, kidney, and liver graft survival were similar between kidney after liver transplants and propensity score-matched simultaneous liver-kidney transplant recipients. CONCLUSION This study demonstrates that after Organ Procurement and Transplantation Network "safety-net" policy implementation, there has been an increase in liver transplant recipients with renal dysfunction who are listed for and undergo kidney transplant with excellent short-term results.

Abstract
Abstract
Background
Polypharmacy is associated with higher rates of adverse drug events and unplanned hospital visits in medical patients. Little is known about polypharmacy in frail older adults undergoing transcatheter (TAVR) or surgical (SAVR) aortic valve replacement.
Purpose
To determine the prevalence and prognostic implications of polypharmacy and potentially inappropriate medications (PIM) following TAVR or SAVR.
Methods
A post hoc analysis of the McGill Frailty Registry was conducted. Patients 70 years of age or older who were discharged alive after TAVR or SAVR at two university hospitals were included. Discharge prescriptions were codified and analyzed using the MedSafer electronic tool that has been validated to flag drug interactions and PIMs considering patient-specific comorbidities. Associations with the primary outcome of 30-day all-cause readmission were examined by logistic regression after adjusting for age, sex, Charlson Comorbidity Index, and procedure type.
Results
The cohort consisted of 495 patients (52% TAVR, 21% isolated SAVR, 27% combined SAVR). The mean age was 80.1±5.5 years with 52% females. The mean number of medications was 10.2±3.7 with 90% having 5 or more medications. A total of 55 patients were readmitted within 30 days. While the total number of medications was not predictive, three specific PIMs were found to be harmful and one PIM was found to be protective for readmission: clopidogrel with warfarin or heparin (OR 3.99; 95% CI 1.47, 10.82), diltiazem with heart failure (OR 3.16; 95% CI 1.04, 36.41), doxazosin or terazosin with hypertension (OR 6.21; 95% CI 0.99, 38.88), and any proton pump inhibitor (OR 0.47; 95% CI 0.26, 0.86). Of note, the combination of clopidogrel with direct oral anticoagulants was not found to be harmful for readmission.
Conclusion
The prevalence of polypharmacy is elevated in older patients undergoing TAVR or SAVR. Specific PIMs, but not total number of medications prescribed, were found to be associated with potentially preventable readmissions.

Abstract
Abstract
Background
Although many literatures demonstrated heavy rainfall was associated with an increased risk of acute gastroenteritis via contaminated food and water, we hypothesized there is no association between rainfall and paediatric acute gastroenteritis in a setting with high-standard food and water hygiene.
Methods
Intestinal infection-related hospital admissions data during 1998-2018 for children under 5 years of age in Hong Kong were collected. Meteorological data were collected from the Hong Kong Observatory. A distributed lag nonlinear model was employed to examine the associations between meteorological factors and the risk of hospital admissions due to acute gastroenteritis.
Results
Rainfall did not exhibit a statistically significant association with the risk of paediatric admission due to acute gastroenteritis but low temperature, low and high relative humidity did. The risk was 6.3% higher (95% confidence interval: 0.3% to 12.6%) when temperature was at 15.1oC (i.e. the 5th percentile). The adjusted relative risk was statistically significantly higher when relative humidity was ≤73.0% or ≥ 84.0%.
Conclusions
Text: We suggest rainfall playing a minor role in disease transmission via contaminated food and water in affluent societies like Hong Kong. Instead, we speculate low temperature and humidity extremes have greater impact on transmission through increased stability and infectivity of enteric viruses.
Key messages
Weather plays a minor role in food and water contamination in affluent societies.
Low temperature and humidity extremes might improve survival of enteric viruses.

Abstract
As the SARS-COV-2 pandemic created the need for social distancing and the implementation of nonessential travel bans, residency and fellowship programs have moved toward a web-based virtual process for applicant interviews. As part of the Society of Asian Academic Surgeons 5th Annual Meeting, an expert panel was convened to provide guidance for prospective applicants who are new to the process. This article provides perspectives from applicants who have successfully navigated the surgical subspecialty fellowship process, as well as program leadership who have held virtual interviews.

Abstract
BACKGROUND Level 1 evidence for multimodal treatment of resectable gastric adenocarcinoma from the Intergroup 0116 (2001) and MAGIC (2006) trials demonstrated survival benefit of adjuvant chemoradiation (CRT) and perioperative chemotherapy, respectively. We evaluated the adoption of evidence-based treatment in the post-MAGIC era and its impact on survival. METHODS A total of 7058 patients with resectable gastric adenocarcinoma undergoing definitive surgical resection between 2004 and 2015 were analyzed using the National Cancer Database. RESULTS Over the study period, the proportion of patients receiving adjuvant CRT decreased from 19.1% to 9.1%, while perioperative chemotherapy increased from 1.9% to 28.6%. Utilization of perioperative chemotherapy surpassed adjuvant CRT in 2011. Evidence-based treatment (either perioperative chemotherapy or adjuvant CRT) had better overall survival (OS) than other treatments for clinical stage II-III patients (p < 0.05). On multivariate analysis of the whole study period, evidence-based treatments were associated with better OS (HR 0.67 [0.60-0.74], p < 0.05). Only 360/1262 (28.5%) patients in the perioperative chemotherapy group completed postoperative therapy, which was associated with improved OS (p < 0.05). For clinical stage III patients (n = 2402), only 806 (33.6%) received evidence-based treatment, while 487 (22.2%) underwent surgery alone. On multivariate analysis of these patients between 2010 and 2015, both perioperative chemotherapy (HR 0.49 [0.35-0.68]) and adjuvant CRT (HR 0.31 [0.21-0.44]) were associated with better OS than surgery alone (p < 0.05). CONCLUSIONS Since the INT-0116 and MAGIC trials, utilization of evidence-based treatments for resectable gastric adenocarcinoma has increased, with perioperative chemotherapy surpassing adjuvant CRT as the preferred practice. However, overall utilization of these regimens remains quite low nationally despite association with improved OS.

Abstract
BACKGROUND An increasing number of patients achieve a pathologic complete response (pCR) after neoadjuvant chemoradiation for locally advanced rectal cancer. Consensus guidelines continue to recommend oncologic resection followed by adjuvant chemotherapy in these patients. We hypothesize that there is significant variability in compliance with this recommendation. METHODS The National Cancer Database was queried from 2006 to 2015 for patients with locally advanced rectal cancer who underwent neoadjuvant chemoradiation followed by oncologic resection with a pCR (ypT0N0). Hierarchical logistic regression models were used to generate risk and reliability-adjusted rates of adjuvant chemotherapy utilization in patients with pCR at each hospital. RESULTS In total, 2421 pCR patients were identified. Five-year overall survival was improved in pCR patients who received adjuvant chemotherapy compared with those who did not (92 vs. 85%, p < 0.01). Multivariate analysis indicated that improvement in overall survival remained associated with adjuvant chemotherapy (HR 0.60, 95% CI 0.44-0.82, p < 0.01). The mean adjuvant chemotherapy utilization rate among hospitals was 32%. There was an upward trend in use over the past decade, but two-thirds still do not receive the recommended therapy. High chemotherapy utilizer hospitals were more likely to be academic centers (54.9 vs. 45.9%, p < 0.01) when compared with low chemotherapy utilizers. CONCLUSION Adjuvant chemotherapy is associated with improved survival in rectal cancer patients with pCR following neoadjuvant chemoradiation and oncologic resection. However, utilization among centers in the USA was only 32% with significant variability across centers. National efforts are needed to standardize treatment patterns according to national guidelines.

Abstract
Supplemental Digital Content is available in the text. This single-center retrospective study evaluated a protocol for the intubation of patients with confirmed or suspected coronavirus disease 2019 (COVID-19). Twenty-one patients were intubated, 9 of whom were found to have COVID-19. Adherence to the airway management protocol was high. COVID-19 patients had lower peripheral capillary oxygen saturation by pulse oximetry (Spo2) nadirs during intubation (Spo2, 73% [72%–77%] vs 89% [86%–94%], P = .024), and a greater percentage experienced severe hypoxemia defined as Spo2 ≤80% (89% vs 25%, P = .008). The incidence of severe hypoxemia in COVID-19 patients should be considered in the development of guidelines that incorporate high-flow nasal cannula and noninvasive positive pressure ventilation.

Abstract
OBJECTIVES We reported previously on an exteriorized-uterus fetoscopic repair for open neural tube defect (ONTD) using a single-layer closure (SLC) technique. However, because SLC was associated with a high rate of cerebrospinal fluid (CSF) leakage at birth, we developed a three-layer closure (3LC) technique comprising a bovine collagen patch, a myofascial layer and a skin layer. The aims of this study were to compare SLC and 3LC in terms of intraoperative, postoperative and obstetric outcomes, as well as short-term neonatal neurologic and non-neurologic outcomes. METHODS This was a retrospective analysis of prospectively collected data, from 32 consecutive SLC controls and 18 consecutive 3LC cases, that underwent exteriorized-uterus two-port fetoscopic repair of ONTD at our center, between April 2014 and December 2018. All patients satisfied the Management of Myelomeningocele Study (MOMS) criteria. Obstetric, maternal, fetal and early neonatal outcomes were compared between the SLC and 3LC groups. RESULTS Maternal demographics and mean gestational age (GA) at fetal surgery (25.0 ± 0.7 vs 25.0 ± 0.5 weeks' gestation; P = 0.96), and at delivery (36.5 ± 3.5 vs 37.6 ± 3.0 weeks; P = 0.14), were similar between the SLC and 3LC groups, respectively. The rate of preterm prelabor rupture of membranes (PPROM) < 37 weeks (28% vs 29%; P = 0.9), mean GA at PPROM (32.3 ± 3.4 vs 32.7 ± 1.9 weeks; P = 0.83) and rate of vaginal delivery (50% vs 47%; P = 0.84) were similar for the SLC vs 3LC groups, respectively. In pregnancies that had SLC compared with those that had 3LC, there was a significantly higher incidence of CSF leakage at birth (8/32 (25%) vs 0/17 (0%); P = 0.02) and a significantly lower rate of reversal of hindbrain herniation at 6 weeks postoperatively (18/30 (60%) vs 14/15 (93%); P = 0.02). The rate of infants that met the MOMS criteria for shunt placement or died before 12 months of age (23/31 (74%) vs 7/12 (58%); P = 0.31) and those that required treatment for hydrocephalus by 12 months (15/32 (47%) vs 4/12 (33%); P = 0.42) were similar between the SLC and 3LC groups, respectively. CONCLUSIONS Compared to SLC, 3LC preserves the fetal and obstetric benefits of fetoscopic repair and shows improved rates of CSF leakage and reversal of hindbrain herniation at 6 weeks postoperatively.

Abstract
The increasing obesity epidemic has major implications in the realm of transplantation. Patients with obesity face barriers in access to transplant and unique challenges in perioperative and postoperative outcomes. Because of comorbidities associated with obesity, along with the underlying end-stage organ disease leading to transplant candidacy, these patients may not even be referred for transplant evaluation, much less be waitlisted or actually undergo transplant. However, the use of bariatric surgery in this population can help optimize the transplant candidacy of patients with obesity and end-stage organ disease and improve perioperative and postoperative outcomes. We review the impact of obesity on kidney, liver, and cardiothoracic transplant candidates and recipients and explore potential interventions to address obesity in these populations.

Abstract
BACKGROUND Postoperative complications (POCs) are associated with worse oncologic outcomes in various cancer histologies. The impact of POCs on the survival of patients with appendiceal or colorectal cancer after cytoreductive surgery (CRS) and heated intraperitoneal chemotherapy (HIPEC) is unknown. METHODS The US HIPEC Collaborative (2000-2017) was reviewed for patients who underwent CCR0/1 CRS/HIPEC for appendiceal/colorectal cancer. The analysis was stratified by noninvasive appendiceal neoplasm versus invasive appendiceal/colorectal adenocarcinoma. The POCs were grouped into infectious, cardiopulmonary, thromboembolic, and intestinal dysmotility. The primary outcomes were overall survival (OS) and recurrence-free survival (RFS). RESULTS Of the 1304 patients, 33% had noninvasive appendiceal neoplasm (n = 426), and 67% had invasive appendiceal/colorectal adenocarcinoma (n = 878). In the noninvasive appendiceal cohort, POCs were identified in 55% of the patients (n = 233). The 3-year OS and RFS did not differ between the patients who experienced a complication and those who did not (OS, 94% vs 94%, p = 0.26; RFS, 68% vs 60%, p = 0.15). In the invasive appendiceal/colorectal adenocarcinoma cohort, however, POCs (63%; n = 555) were associated with decreased 3-year OS (59% vs 74%; p < 0.001) and RFS (32% vs 42%; p < 0.001). Infectious POCs were the most common (35%; n = 196). In Multivariable analysis accounting for gender, peritoneal cancer index (PCI), and incomplete resection (CCR1), infectious POCs in particular were associated with decreased OS compared with no complication (hazard ratio [HR] 2.08; p < 0.01) or other types of complications (HR, 1.6; p < 0.01). Similarly, infectious POCs were independently associated with worse RFS (HR 1.61; p < 0.01). CONCLUSION Postoperative complications are associated with decreased OS and RFS after CRS/HIPEC for invasive histology, but not for an indolent disease such as noninvasive appendiceal neoplasm, and this association is largely driven by infectious complications. The exact mechanism is unknown, but may be immunologic. Efforts must target best practices and standardized prevention strategies to minimize infectious postoperative complications.

Abstract
BACKGROUND The evolving landscape of academic surgery demands leaders who are not only effective clinicians and researchers, but also administrators able to navigate complex hospital organizations, financial pressures in the era of quality measures, and inclusion of an increasingly diverse workforce. The aim of this study was to characterize achievements and assess perspectives in becoming a surgical chair in order to guide young surgeons in their career trajectories to surgical leadership. METHODS A survey encompassing demographics, surgical training, nonmedical advanced degrees, academic advancement, and leadership experiences was sent via electronic mail to members of the American College of Surgeons Society of Surgical Chairs in December 2018. RESULTS Of 191 Society of Surgical Chairs members, 52 (27.2%) completed the survey, with 6 (11.5%) women, 40 (76.9%) white, and the majority becoming chair between ages 46 and 60 (n = 39, 75.0%). Training beyond residency included fellowships (n = 41, 78.8%) and advanced nonmedical degrees (n = 15, 28.8%). Median H-index was 47 (range 10-120) with 126 (5-500) research publications, and grants received was 2 (0-38) for federal and 5 (0-43) for industry. Female chairs appear to have fewer nonmedical degrees (n = 1) and no difference in age at becoming chair (66.7% vs 79.6% between ages 46 and 60), H-index (26 [10-41] vs 49 [17-120]), or publications (93 [10-189] vs 150 [5,500]). Prior educational (n = 36, 69.2%) and clinical (n = 44, 84.6%) leadership roles were common, with 30 chairs (57.7%) having held both roles. Experiences which respondents felt have most helped them function as chair included serving as a clinical division director (n = 37, 71.2%), residency program director (n = 28, 53.8%), leadership courses (n = 28, 53.8%), a research career (n = 22, 42.3%), and being a vice/interim chair (n = 15, 28.8%). Personal traits felt to be most important in becoming a successful chair included being effective at communication (n = 37, 71.2%), collaborative (n = 35, 67.3%), trustworthy (n = 30, 57.7%), and a problem-solver (n = 27, 51.9%). CONCLUSION Becoming a department surgical chair often involves not only surgical subspecialty expertise, but also nonmedical training and prior leadership roles, which help facilitate development of skills integral to navigating the collaborative and diverse nature of academic surgery in the current era.

Abstract
BACKGROUND The ACOSOG Z0011 trial has essentially eliminated axillary lymph node dissection (ALND) in breast conserving therapy (BCT) patients with clinical T1/T2 and 1-2 positive sentinel lymph nodes (SLNs). Currently, ALND is recommended for positive SLNs unless ACOSOG Z0011 criteria are applicable. We aimed to assess the national trends and axillary management before and after the publication of ACOSOG Z0011 for larger tumors. METHODS An IRB-approved study evaluated the National Cancer Database from 2006 to 2016. Women with clinical T3/T4, N0 who otherwise fit ACOSOG Z0011 criteria were included. Neoadjuvant systemic therapy or known nodal disease was excluded. Clinicopathologic data were compared between two timeframes based on ACOSOZ Z0011 publication and by axillary management. Patients were categorized into SLNB alone (1-5 lymph nodes examined) and ALND (≥10 lymph nodes examined) groups. RESULTS A total of 230 women fit inclusion criteria, of whom 36% underwent ALND. ALND use decreased from 54% in 2006 to 14% in 2016 (P < 0.01). Comparing ALND to SLNB alone within the pre-Z0011 era, comprehensive community cancer programs had higher proportions of ALND, whereas academic centers had higher rates of SLND alone (P = 0.03). Comparing similar axillary management between eras, SLNB-alone patients in the post-Z0011 era had higher pT and pN stages, were less likely to be Her2 positive, and were more likely to receive systemic treatment. CONCLUSIONS There is a national trend to forgo ALND in women who have tumors larger than those included in the Z0011 criteria without any clear clinicopathologic indications.

Abstract
Simultaneous liver-kidney transplantation (SLKT) is indicated for patients with end-stage liver disease (ESLD) and concurrent renal insufficiency. En bloc SLKT is an alternative to traditional separate implantations, but studies comparing the two techniques are limited. The en bloc technique maintains renal outflow via donor infrahepatic vena cava and inflow via anastomosis of donor renal artery to donor splenic artery. Comparison of recipients of en bloc (n = 17) vs traditional (n = 17) SLKT between 2013 and 2017 was performed. Recipient demographics and comorbidities were similar. More recipients of traditional SLKT were dialysis dependent (82.4% vs 41.2%, P = .01) with lower baseline pretransplant eGFR (14 vs 18, P = .01). En bloc SLKT was associated with shorter kidney cold ischemia time (341 vs 533 minutes, P < .01) and operative time (374 vs 511 minutes, P < .01). Two en bloc patients underwent reoperation for kidney allograft inflow issues due to kinking and renal steal. Early kidney allograft dysfunction (23.5% in both groups), 1-year kidney graft survival (88.2% vs 82.4%, P = 1.0), and posttransplantation eGFR were similar between groups. In our experience, the en bloc SLKT technique is safe and feasible, with comparable outcomes to the traditional method.

Abstract
OBJECTIVE To evaluate whether elective preterm delivery (ED) at 34 weeks is of postnatal benefit to infants with isolated gastroschisis compared with routine obstetric care (RC). METHODS Between May 2013 and September 2015, all women with a sonographic diagnosis of fetal gastroschisis referred to a single tertiary center, before 34 weeks' gestation, were invited to participate in this study. Eligible patients were randomized to ED (induction of labor at 34 weeks) or RC (spontaneous labor or delivery by 37-38 weeks, based on standard obstetric indications). The primary outcome measure was length of time on total parenteral nutrition (TPN). Secondary outcomes were time to closure of gastroschisis and length of stay in hospital. Outcome variables were compared using appropriate statistical methods. Analysis was based on intention-to-treat. RESULTS Twenty-five women were assessed for eligibility, of whom 21 (84%; 95% CI, 63.9-95.5%) agreed to participate in the study; of these, 10 were randomized to ED and 11 to RC. The trial was stopped at the first planned interim analysis due to patient safety concerns and for futility; thus, only 21 of the expected 86 patients (24.4%; 95% CI, 15.8-34.9%) were enrolled. Median gestational age at delivery was 34.3 (range, 34-36) weeks in the ED group and 36.7 (range, 27-38) weeks in the RC group. One patient in the ED group delivered at 36 weeks following unsuccessful induction at 34 weeks. Neonates of women who underwent ED, compared to those in the RC group, showed no difference in the median number of days on TPN (54 (range, 17-248) vs 21 (range, 9-465) days; P = 0.08), number of days to closure of gastroschisis (7 (range, 0-15) vs 5 (range, 0-8) days; P = 0.28) and length of stay in hospital (70.5 (range, 22-137) vs 31 (range, 19-186) days; P = 0.15). However, neonates in the ED group were significantly more likely to experience late-onset sepsis compared with those in the RC group (40% (95% CI, 12.2-73.8%) vs 0%; P = 0.03). CONCLUSION This study demonstrates no benefit of ED of fetuses with gastroschisis when postnatal gastroschisis management is similar to that used in routine care. Rather, the data suggest that ED is detrimental to infants with gastroschisis. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
BACKGROUND Cytoreductive surgery and hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) results in significant morbidity and readmissions. Previous studies have been limited by single-institution design or lack of tumor details in the database used. METHODS The 12-institution US HIPEC Collaborative Database was queried between 1999 and 2017. Preoperative and intraoperative patient and tumor details were analyzed for associations with readmissions. RESULTS A total of 2017 of 2372 cases were included in the analysis. The 30-day readmission rate was 15.9% (n = 321). Common indications for readmission included failure to thrive (29.9%), infection (23.6%), and ileus/bowel obstruction (15.1%). The readmitted cohort had more complications, including intra-abdominal abscess (21.2% vs 6.2%), ileus (28.0% vs 17.2%), anastomotic leak (11.2% vs 2.2%), enteric fistula (5.6% vs 1.5%), deep venous thrombosis (6.2% vs 2.5%), and pulmonary embolism (6.9% vs 2.5%). Factors independently associated with readmission (p < 0.05) included ECOG score ≥ 3 (OR 3.4), depression (OR 2.4), total parenteral nutrition (OR 3.6), low anterior resection or partial colectomy (OR 2.0), and stoma creation (OR 2.2). Factors not associated included neoadjuvant chemotherapy, peritoneal cancer index, and completeness of cytoreduction. Readmission rate between 31 and 90 days was 3.9% (n = 78). Independent predictors (p < 0.05) included operative time (OR 1.1), low anterior resection or partial colectomy (OR 1.7), and stoma creation (OR 2.2). CONCLUSIONS In the largest study to date examining readmissions after CRS-HIPEC, 30-day readmission rate was 15.9%. Tumor factors failed to predict readmission, whereas preoperative functional status and depression along with individual cytoreductive procedures predicted readmission. Patients with these risk factors or postoperative complications may benefit from closer post-discharge monitoring.

Abstract
Anatomy played a significant role in the establishment of academies in art, initially in Italy and France, and then more widely in Europe and the Americas. This paper considers the role of anatomy in two such academies, the Royal Academy of Arts in London, and the Royal Hibernian Academy of Arts in Dublin. In both cases, anatomy teaching for art students was formalised by the appointment of a Professor of Anatomy, positions that continue to this day. The first Professor of Anatomy in the RA, William Hunter, set the standard by delivering lectures, carrying out dissections and producing écorchés. Some of his successors have published anatomy books specifically for artists, but their enthusiasm has varied. Unlike the continuity of the RA, the RHA has only had bespoke premises from 1826 to 1916, and from 1985 onwards, and its Schools or School have operated from 1826 to 1942, and from 2008 onwards. Anatomy teaching was a casualty of the decline of the formal art academy in the 20th century, but the fortunes of both are reviving in the early 21st century.

Abstract
The structure of the human body and its parts is of obvious relevance in medicine, but it has also played a role in art. Accurate observation of surface or external anatomy is essential in both disciplines, and its understanding has been enhanced by knowledge of what is found beneath the skin, the internal anatomy, usually based on dissection. The role of anatomy in art in general, and in academies of art in particular, is the theme of this paper. The revival of dissection in 14th-century Italy was, if not causative, at least coincidental with the Renaissance. In 1563, Vasari founded the Accademia del Disegno in Florence, with una Anatomia included in its regulations. As a liberal art taught by university graduates, anatomy helped raise the status of painters and sculptors from artisans to artists and from guild to academy. Anatomy teaching was required in subsequent academies in Rome (1593) and Paris (1648), where the pattern of drawing from drawings, from casts, and from life was established and a Professor of Anatomy appointed in 1777. Anatomy was central to two of the Academy's most important genres, history painting and portraiture. The Academy system, with its emphasis on anatomy, spread to other European cities and to the Caribbean and the Americas from the 17th to the 19th centuries. This paper is concerned with the role of anatomy in the founding of art academies in general, while its companion paper, 'A Tale of Two Cities', considers the cases of the academies in London and Dublin in particular.

Abstract
OBJECTIVE Fetal endoscopic tracheal occlusion (FETO) is associated with increased perinatal survival and reduced need for extracorporeal membrane oxygenation (ECMO) in fetuses with severe congenital diaphragmatic hernia (CDH). This study evaluates the impact of FETO on the resolution of pulmonary hypertension (PH) in fetuses with isolated CDH. METHODS We reviewed retrospectively the medical records of all fetuses evaluated for CDH between January 2004 and July 2017 at a single institution. Fetuses with additional major structural or chromosomal abnormalities were excluded. CDH cases were classified retrospectively into mild, moderate and severe groups based on prenatal magnetic resonance imaging indices (observed-to-expected total fetal lung volume and percentage of intrathoracic liver herniation). Presence of PH was determined based on postnatal echocardiograms. Logistic regression analyses were performed to evaluate the relationship between FETO and resolution of PH by 1 year of age while controlling for side of the CDH, use of ECMO, gestational age at diagnosis, gestational age at delivery, fetal gender, sildenafil use at discharge and CDH severity. Resolution of PH by 1 year of age was compared between a cohort of fetuses with severe CDH that underwent FETO and a cohort that did not have the procedure (non-FETO). A subanalysis was performed restricting the analysis to isolated left CDH. Parametric and non-parametric tests were used for comparisons. RESULTS Of 257 CDH cases evaluated, 72% (n = 184) had no major structural or chromosomal anomalies of which 58% (n = 107) met the study inclusion criteria. The FETO cohort consisted of 19 CDH cases and the non-FETO cohort (n = 88) consisted of 31 (35%) mild, 32 (36%) moderate and 25 (28%) severe CDH cases. All infants with severe CDH, regardless of whether they underwent FETO, had evidence of neonatal PH. FETO (OR, 3.57; 95% CI, 1.05-12.10; P = 0.041) and ECMO (OR, 5.01; 95% CI, 2.10-11.96; P < 0.001) were independent predictors of resolution of PH by 1 year of age. A higher proportion of infants with severe CDH that underwent FETO had resolution of PH by 1 year after birth compared with infants with severe CDH in the non-FETO cohort (69% (11/16) vs 28% (7/25); P = 0.017). Similar results were observed when the analysis was restricted to cases with left-sided CDH (PH resolution in 69% (11/16) vs 28% (5/18); P = 0.032). CONCLUSION In infants with severe CDH, FETO and ECMO are independently associated with increased resolution of PH by 1 year of age. Copyright © 2019 ISUOG. Published by John Wiley & Sons Ltd.

Abstract
Obesity has become an epidemic in the United States over the past decade, and recent studies have shown this trend in the liver transplantation (LT) population. These patients may be candidates for laparoscopic sleeve gastrectomy (LSG) to promote significant and sustained weight loss to prevent recurrence of nonalcoholic steatohepatitis. However, safety remains a concern, and efficacy in this setting is uncertain. A single-institution database from 2014 to 2018 was queried for patients undergoing LSG following LT. The selection criteria for surgery were consistent with National Institutes of Health guidelines, and patients were at least 6 months after LT. A total of 15 patients (median age, 59.0 years; Caucasian, 86.7%; and female, 60%) underwent LSG following LT. Median time from LT to LSG was 2.2 years with a median follow-up period of 2.6 years. The median hospital length of stay (LOS) was 2 days after LSG. Mortality and rate of liver allograft rejection was 0, and there was 1 postoperative complication (a surgical site infection). Following LSG, body mass index (BMI) decreased from 42.7 to 35.9 kg/m2 (P < 0.01), and in 12 patients with at least 1 year of follow-up, the total body weight loss was 20.6%. Following LSG in patients with diabetes, the median daily insulin requirements decreased from 98 (49-118) to 0 (0-29) units/day (P = 0.02), and 60% discontinued insulin. Post-LT patients had a similar decrease in BMI and reduction in comorbidities at 1 year compared with a matched non-LT patient cohort. In the largest patient series to date, we show that LSG following LT is safe, effective, and does not increase the incidence of liver allograft rejection. Larger longer-term studies are needed to confirm underlying metabolic changes following LSG.

Abstract
BACKGROUND AND PURPOSE MR imaging is not routinely used to image the extracranial facial nerve. The purpose of this study was to determine the extent to which this nerve can be visualized with a CISS sequence and to determine the feasibility of using that sequence for locating the nerve relative to tumor. MATERIALS AND METHODS Thirty-two facial nerves in 16 healthy subjects and 4 facial nerves in 4 subjects with parotid gland tumors were imaged with an axial CISS sequence protocol that included 0.8-mm isotropic voxels on a 3T MR imaging system with a 64-channel head/neck coil. Four observers independently segmented the 32 healthy subject nerves. Segmentations were compared by calculating average Hausdorff distance values and Dice similarity coefficients. RESULTS The primary bifurcation of the extracranial facial nerve into the superior temporofacial and inferior cervicofacial trunks was visible on all 128 segmentations. The mean of the average Hausdorff distances was 1.2 mm (range, 0.3-4.6 mm). Dice coefficients ranged from 0.40 to 0.82. The relative position of the facial nerve to the tumor could be inferred in all 4 tumor cases. CONCLUSIONS The facial nerve can be seen on CISS images from the stylomastoid foramen to the temporofacial and cervicofacial trunks, proximal to the parotid plexus. Use of a CISS protocol is feasible in the clinical setting to determine the location of the facial nerve relative to tumor.

Abstract
BACKGROUND For patients with peritoneal carcinomatosis undergoing cytoreductive surgery with heated intraperitoneal chemotherapy (CRS/HIPEC), incomplete cytoreduction (CCR2/3) confers morbidity without survival benefit. The aim of this study is to identify preoperative factors which predict CCR2/3. METHODS All patients who underwent curative-intent CRS/HIPEC of low/high-grade appendiceal, colorectal, or peritoneal mesothelioma cancers in the 12-institution US HIPEC Collaborative from 2000 to 2017 were included (n = 2027). The primary aim is to create an incomplete-cytoreduction risk score (ICRS) to predict CCR2/3 CRS utilizing preoperative data. ICRS was created from a randomly selected cohort of 50% of patients (derivation cohort) and verified on the remaining patients (validation cohort). RESULTS Within our derivation cohort (n = 998), histology was low-grade appendiceal neoplasms in 30%, high-grade appendiceal tumor in 41%, colorectal tumor in 22%, and peritoneal mesothelioma in 8%. CCR0/1 was achieved in 816 patients and CCR 2/3 in 116 patients. On multivariable analysis, preoperative factors associated with incomplete cytoreduction were male gender [odds ratio (OR) 3.4, p = 0.007], presence of ascites (OR 2.8, p = 0.028), cancer antigen (CA)-125 ≥ 40 U/mL (OR 3.4, p = 0.012), and carcinoembryonic antigen (CEA) ≥ 4.2 ng/mL (OR 3.2, p = 0.029). Each preoperative factor was assigned a score of 0 or 1 to form an ICRS from 0 to 4. Scores were grouped as zero (0), low (1-2), or high (3-4). Incidence of CCR2/3 progressively increased by risk group from 1.6% in zero to 13% in low and 39% in high. When ICRS was applied to the validation cohort (n = 1029), this relationship was maintained. CONCLUSION The incomplete cytoreduction risk score incorporates preoperative factors to accurately stratify the risk of CCR2/3 resection in CRS/HIPEC. This score should not be used in isolation, however, to exclude patients from surgery.

Abstract
BACKGROUND Selection of patients for hyperthermic intraperitoneal chemotherapy (HIPEC) continues to evolve. We hypothesized that adjuvant HIPEC for patients at high-risk of peritoneal progression is safe and associated with favorable outcomes. METHODS The institutional database of a high-volume center was queried for patients with high-risk disease undergoing HIPEC with a peritoneal carcinomatosis index (PCI) of 0. High-risk patients were defined as those with ruptured primary tumors or locally advanced (T4) disease. RESULTS 37 patients underwent adjuvant HIPEC, with a median follow-up of 5.2 years. 54% had low-grade (LG) tumors while 46% had high-grade (HG) tumors. No patients underwent neoadjuvant chemotherapy, while eleven patients (32.4%) received adjuvant chemotherapy. There were no perioperative mortalities, and the overall complication rate was 43%. For the entire cohort, five year recurrence-free survival (RFS) and overall survival (OS) were 77% and 100%, respectively. Five year RFS and OS were 75% and 100% for LG patients and 81% and 100% for HG patients, respectively. CONCLUSIONS Adjuvant HIPEC for patients at high-risk of peritoneal progression, with PCI 0, is safe and associated with favorable long-term survival. Additional prospective investigation is needed to identify patient populations who may benefit most from HIPEC.

Abstract
Surgical management of primary liver and biliary tract tumors has evolved over the past several decades, resulting in improved outcomes in these malignancies with historically poor prognoses. Expansion of patient selection criteria, progress in neoadjuvant and adjuvant therapies, development of techniques to increase future liver remnant, and the select utilization of liver transplantation have all contributed to increasing the patient pool for surgical intervention. Ongoing and future studies need to focus on improving multimodality treatment regimens and further refining the selection criteria for transplantation in order to optimize utilization of limited organ resources.

Abstract
BACKGROUND No guidelines exist for surveillance following cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS/HIPEC) for appendiceal and colorectal cancer. The primary objective was to define the optimal surveillance frequency after CRS/HIPEC. METHODS The U.S. HIPEC Collaborative database (2000-2017) was reviewed for patients who underwent a CCR0/1 CRS/HIPEC for appendiceal or colorectal cancer. Radiologic surveillance frequency was divided into two categories: low-frequency surveillance (LFS) at q6-12mos or high-frequency surveillance (HFS) at q2-4mos. Primary outcome was overall survival (OS). RESULTS Among 975 patients, the median age was 55 year, 41% were male: 31% had non-invasive appendiceal (n = 301), 45% invasive appendiceal (n = 435), and 24% colorectal cancer (CRC; n = 239). With a median follow-up time of 25 mos, the median time to recurrence was 12 mos. Despite less surveillance, LFS patients had no decrease in median OS (non-invasive appendiceal: 106 vs. 65 mos, p < 0.01; invasive appendiceal: 120 vs. 73 mos, p = 0.02; colorectal cancer [CRC]: 35 vs. 30 mos, p = 0.8). LFS patients had lower median PCI scores compared with HFS (non-invasive appendiceal: 10 vs. 19; invasive appendiceal: 10 vs. 14; CRC: 8 vs. 11; all p < 0.01). However, on multivariable analysis, accounting for PCI score, LFS was still not associated with decreased OS for any histologic type (non-invasive appendiceal: hazard ratio [HR]: 0.28, p = 0.1; invasive appendiceal: HR: 0.73, p = 0.42; CRC: HR: 1.14, p = 0.59). When estimating annual incident cases of CRS/HIPEC at 375 for non-invasive appendiceal, 375 invasive appendiceal and 4410 colorectal, LFS compared with HFS for the initial two post-operative years would potentially save $13-19 M/year to the U.S. healthcare system. CONCLUSIONS Low-frequency surveillance after CRS/HIPEC for appendiceal or colorectal cancer is not associated with decreased survival, and when considering decreased costs, may optimize resource utilization.

Abstract
BACKGROUND The purpose of the study was to characterize the prevalence and impact of perioperative blood use for patients undergoing hepatic lobectomy at academic medical centers. METHODS The University HealthSystem Consortium (UHC) database was queried for hepatic lobectomies performed between 2011 and 2014 (n = 6476). Patients were grouped according to transfusion requirements into high (>5 units, 7%), medium (2-5 units, 6%), low (1 unit, 8%), and none (0 units, 79%) during hospital stay for comparison of outcomes. RESULTS Over 20% of patients undergoing hepatic lobectomy received blood perioperatively, of which 35% required more than 5 units. Patients with high transfusion requirements had increased severity of illness (p < 0.01). High transfusion requirements correlated with increased readmission rates (23.4% vs. 19.2% vs. 16.6% vs. 13.5%), total direct costs ($31,982 vs. $20,859 vs. $19,457 vs. $16,934), length of stay (9 days vs. 8 vs. 7 vs. 6), and in-hospital mortality (10.8% vs. 2.0% vs. 0.9% vs. 2.0%) compared to medium, low, and no transfusion amounts (all p < 0.01). Neither center nor surgeon volume were associated with transfusion use. CONCLUSION High transfusion requirements after hepatic lobectomy in the United States are associated with worse perioperative quality measures, but may not be influenced by center or surgeon volume.

Abstract
BACKGROUND Our goal was to evaluate the relationship between perioperative fluid administration and the development of clinically relevant postoperative pancreatic fistula (CR-POPF) after pancreaticoduodenectomy (PD). METHODS Retrospectively, we analyzed fluid balance over the first 72 h in 104 consecutive patients who underwent PD between 2013 and 2017. Patients were categorized into tertiles (low, medium, and high) by net fluid balance. RESULTS POPF was identified in 17.3% of patients (n = 18). No significant demographic differences were identified among tertiles. Similarly, there were no differences in ASA, smoking status, hemoglobin A1C, pathologic findings, operative time, blood loss, intraoperative fluid administration, use of pancreatic stents, use of epidurals, or postoperative lactate. Patients with high 72-h net fluid balance had significantly increased rates of POPF compared with those in the medium and low tertiles (31.4% vs. 11.4% vs. 8.8%, p = 0.02). On multivariate analysis, increasing net fluid balance remained associated with CR-POPF (OR 1.26, CI 1.03-1.55, p = 0.03). CONCLUSION High net 72-h fluid balance is an independent predictor of POPF after PD. Given ongoing efforts to minimize PD morbidity, net fluid balance may represent a clinical predictor and, possibly, a modifiable target for prevention of POPF.

Abstract
The pointwise encoding time reduction with radial acquisition (PETRA) ultrashort echo time MR imaging sequence at 3T enables visualization of the facial nerve from the brain stem, through the temporal bone, to the stylomastoid foramen without intravenous contrast. Use of the PETRA sequence, or other ultrashort echo time sequences, should be considered in the MR imaging evaluation of certain skull base tumors and perhaps other facial nerve and temporal bone pathologies.

Abstract
BACKGROUND Diabetes self-management education (DSME) improves glycemic control and health outcomes in patients with diabetes. OBJECTIVE A process evaluation of a two-year pilot intervention examined the feasibility and acceptability of undergraduate volunteers as Patient Partners to foster DSME participation among the underserved.Design setting, and participants. In the setting of a student-run free clinic, 22 patients enrolled in DSME were paired with 16 undergraduate volunteers. During the DSME courses, Patient Partners assisted patients during classes, called patients weekly, and accompanied patients to clinic appointments.Key process evaluation results. Average attendance at DSME classes was 79.4% and 94.7% for patients and Patient Partners, respectively. Sixty-three percent of phone calls were successful and Patient Partners attended 50% of appointments with their patients. Focus groups demonstrated resounding acceptability of the Patient Partner role. CONCLUSIONS Volunteer undergraduate Patient Partners are a beneficial adjunct to DSME delivery in the resource-constrained environment of a student-run free clinic.

Abstract
Human retinal ganglion cells (RGCs) derived from pluripotent stem cells (PSCs) have anticipated value for human disease study, drug screening, and therapeutic applications; however, their full potential remains underdeveloped. To characterize RGCs in human embryonic stem cell (hESC) derived retinal organoids we examined RGC markers and surface antigen expression and made comparisons to human fetal retina. RGCs in both tissues exhibited CD184 and CD171 expression and distinct expression patterns of the RGC markers BRN3 and RBPMS. The retinal progenitor cells (RPCs) of retinal organoids expressed CD184, consistent with its expression in the neuroblastic layer in fetal retina. In retinal organoids CD184 expression was enhanced in RGC competent RPCs and high CD184 expression was retained on post-mitotic RGC precursors; CD171 was detected on maturing RGCs. The differential expression timing of CD184 and CD171 permits identification and enrichment of RGCs from retinal organoids at differing maturation states from committed progenitors to differentiating neurons. These observations will facilitate molecular characterization of PSC-derived RGCs during differentiation, critical knowledge for establishing the veracity of these in vitro produced cells. Furthermore, observations made in the retinal organoid model closely parallel those in human fetal retina further validating use of retinal organoid to model early retinal development.

Abstract
This paper presents a study to develop a heat index, for use in hot and humid sub-tropical climate in Hong Kong. The study made use of hospitalization data and heat stress measurement data in Hong Kong from 2007 to 2011. The heat index, which is called Hong Kong Heat Index (HKHI), is calculated from the natural wet bulb temperature, the globe temperature, and the dry bulb temperature together with a set of coefficients applicable to the high humidity condition in the summer of Hong Kong. Analysis of the response of hospitalization rate to variation in HKHI and two other heat indices, namely Wet Bulb Globe Temperature (WBGT) and Net Effective Temperature (NET), revealed that HKHI performed generally better than WBGT and NET in reflecting the heat stress impact on excess hospitalization ratio in Hong Kong. Based on the study results, two reference criteria of HKHI were identified to establish a two-tier approach for the enhancement of the heat stress information service in Hong Kong.

Abstract
BACKGROUND As part of ongoing perioperative surgical home implantation process, we applied a previously published algorithm for creation of a maximum surgical blood order schedule (MSBOS) to our operating rooms. We hypothesized that using the MSBOS we could show a reduction in unnecessary preoperative blood testing and associated costs. STUDY DESIGN AND METHODS Data regarding all surgical cases done at UC Irvine Health's operating rooms from January 1, 2011, to January 1, 2014 were extracted from the anesthesia information management systems (AIMS). After the data were organized into surgical specialties and operative sites, blood order recommendations were generated based on five specific case characteristics of the group. Next, we assessed current ordering practices in comparison to actual blood utilization to identify potential areas of wastage and performed a cost analysis comparing the annual hospital costs from preoperative blood orders if the blood order schedule were to be followed to historical practices. RESULTS Of the 19,138 patients who were categorized by the MSBOS as needing no blood sample, 2694 (14.0%) had a type and screen (T/S) ordered and 1116 (5.8%) had a type and crossmatch ordered. Of the 6073 procedures where MSBOS recommended only a T/S, 2355 (38.8%) had blood crossmatched. The cost analysis demonstrated an annual reduction in actual hospital costs of $57,335 with the MSBOS compared to historical blood ordering practices. CONCLUSION We showed that the algorithm for development of a multispecialty blood order schedule is transferable and yielded reductions in preoperative blood product screening at our institution.

Abstract
BACKGROUND The AMPLIFY trial compared apixaban with enoxaparin followed by warfarin for the treatment of acute venous thromboembolism (VTE). OBJECTIVE To perform a subgroup analysis to compare the efficacy and safety of apixaban and enoxaparin followed by warfarin for the treatment of VTE in patients with cancer enrolled in AMPLIFY. PATIENTS/METHODS Patients with symptomatic VTE were randomized to a 6-month course of apixaban or enoxaparin followed by warfarin. The primary efficacy outcome and principal safety outcome were recurrent VTE or VTE-related death and major bleeding, respectively. RESULTS Of the 5395 patients randomized, 169 (3.1%) had active cancer at baseline, and 365 (6.8%) had a history of cancer without active cancer at baseline. Among patients with active cancer, recurrent VTE occurred in 3.7% and 6.4% of evaluable patients in the apixaban and enoxaparin/warfarin groups, respectively (relative risk [RR] 0.56, 95% confidence interval [CI] 0.13-2.37); major bleeding occurred in 2.3% and 5.0% of evaluable patients, respectively (RR 0.45, 95% CI 0.08-2.46). Among patients with a history of cancer, recurrent VTE occurred in 1.1% and 6.3% of evaluable patients in the apixaban and enoxaparin/warfarin groups, respectively (RR 0.17, 95% CI 0.04-0.78); major bleeding occurred in 0.5% and 2.8% of treated patients, respectively (RR 0.20, 95% CI 0.02-1.65). CONCLUSIONS The results of this subgroup analysis suggest that apixaban is a convenient option for cancer patients with VTE. However, additional studies are needed to confirm this concept and to compare apixaban with low molecular weight heparin in these patients.

Abstract
Osteoporosis is one of the most prevalent bone diseases worldwide and is characterised by high levels of bone turnover, a marked loss in bone mass and accumulation of microdamage, which leads to an increased fracture incidence that places a huge burden on global health care systems. Bisphosphonates have been used to treat osteoporosis and have shown great success in conserving bone mass and reducing fracture incidence. In spite of the existing knowledge of the in vivo responses of bone to bisphosphonates, the cellular responses to these drugs have yet to be fully elucidated. In vitro model systems that allow the decoupling of complex highly integrated events, such as bone remodelling, provide a tool whereby these biological processes may be studied in a more simplified context. This study firstly utilised an in vitro model system of bone remodelling and comprising all three major cell types of the bone (osteocytes, osteoclasts and osteoblasts), which was representative of the bone's capacity to sense microdamage and subsequently initiate a basic multicellular unit response. Secondly, this system was used to study the effect of two commonly utilised aminobisphosphonate treatments for osteoporosis, alendronate and zoledronate. We demonstrated that microinjury to osteocyte networks being treated with bisphosphonates modulates receptor activator of nuclear factor kappa-B ligand and osteoprotegerin activity, and subsequently osteoclastogenesis. Furthermore, bisphosphonates increased the osteogenic potential following microinjury. Thus, we have shown for the first time that bisphosphonates act at all three stages of bone remodelling, from microinjury to osteoclastogenesis and ultimately osteogenesis.

Abstract
OBJECTIVES To describe a method of quantifying the amount of liver herniation in fetuses with isolated congenital diaphragmatic hernia (CDH) using two-dimensional ultrasonography and to correlate this finding with neonatal outcome. METHODS Ultrasound images obtained from 77 consecutive fetuses that presented with isolated CDH between January 2004 and July 2012 were reviewed. Liver herniation and thoracic area were measured in a cross-sectional plane of the fetal chest at the level of the four-chamber view of the heart (the same section as is used to measure the lung area-to-head circumference ratio) and the ultrasound-derived liver-to-thoracic area ratio (US-LiTR) was calculated by dividing the liver herniation area by the thoracic area. Receiver-operating characteristics (ROC) curve analysis was used to evaluate the performance of US-LiTR in predicting neonatal outcome (survival to 6 months after delivery and need for extracorporeal membrane oxygenation (ECMO)). In addition, the US-LiTR was compared with the magnetic resonance imaging (MRI)-derived volume ratio (MRI-LiTR) and percentage of liver herniation (MRI-%LH). RESULTS The overall neonatal mortality in the 77 cases with isolated CDH was 20.8% (16/77). ECMO was needed in 35.5% (27/76) of the newborns, with a survival rate of 52%. The US-LiTR was associated statistically with mortality (P < 0.01) and with the need for ECMO (P < 0.01). Good correlations were observed between US-LiTR and MRI-LiTR (r = 0.87; P < 0.001) and between US-LiTR and MRI-%LH (r = 0.90; P < 0.001). Based on ROC curve analysis, all three parameters had similar accuracy in predicting mortality (US-LiTR: area under the ROC curve (AUC), 0.78 (95% CI, 0.65-0.92), P < 0.01; MRI-LiTR: AUC, 0.77 (95% CI, 0.63-0.90), P < 0.01; MRI-%LH: AUC, 0.79 (95% CI, 0.65-0.92), P < 0.01, respectively) as well as the need for ECMO (US-LiTR: AUC, 0.72 (95% CI, 0.60-0.84), P < 0.01; MRI-LiTR: AUC, 0.73 (95% CI, 0.60-0.88), P < 0.01; MRI-%LH: AUC, 0.77 (95% CI, 0.64-0.89), P < 0.01, respectively). CONCLUSIONS Two-dimensional ultrasound measurement of the amount of liver herniation in fetuses with isolated CDH is feasible and demonstrates a predictive accuracy for neonatal outcome similar to that of MRI.

OBJECTIVE To evaluate the impact of the presence of a congenital heart anomaly (CHA) and its potential contribution to morbidity and mortality in infants with congenital diaphragmatic hernia (CDH). METHODS In this retrospective cohort study, prenatal and postnatal data of all newborns diagnosed with CDH between January 2004 and December 2012 in a single center were reviewed. Cases were classified into two groups: those with 'isolated' CDH and those with both CDH and CHA. Patients with CHA were further subclassified into those with a major or minor CHA based on the Risk Adjustment for Congenital Heart Surgery-1 (RACHS-1), and the Society of Thoracic Surgeons-European Association for Cardiothoracic Surgery (STS-EACTS) scoring systems. Patients with associated non-cardiac anomalies, including 'syndromic cases', were excluded from the analysis. Primary and secondary outcomes were survival up to 1 year of age and a need for extracorporeal membrane oxygenation (ECMO), respectively. RESULTS Of the 180 infants with CDH, 41 were excluded because of the presence of non-cardiac associated anomalies, 118 had isolated CDH and 21 had CDH with CHA (16 with minor and five with major CHA). Receiver-operating characteristics curve analysis demonstrated that the best cut-off for survival was when the score for CHA was ≤ 2 for both RACHS-1 (area under the curve (AUC), 0.74 (P = 0.04); sensitivity, 80.0%; specificity, 87.5%) and STS-EACTS (AUC, 0.83 (P = 0.03); sensitivity, 100%; specificity, 87.5%). Survival rate at 1 year was significantly lower in those with CHD and a major CHA (40.0%; P = 0.04) than in those with isolated CDH (77.1%) and those with CDH and a minor CHA (81.3%). We found no significant differences among the groups with regard to the need for ECMO. CONCLUSIONS In general, a milder form of CHA does not appear to have a negative impact on the survival of infants with CDH. However, mortality appears to be significantly higher in infants with CDH and a major form of CHA. The scoring systems appear to be useful as predictors for classifying the effects of CHA in this population of patients.
