AbstractObjectiveCareer paths leading to department chair positions are elusive. Women represent only 11% of academic emergency department (ED) chairs. It is unclear whether the pathway to chair is different for men and women; the characteristics, achievements, and qualifications among those who become ED chairs is unknown.MethodsThis study is a cross‐sectional analysis of curriculum vitae (CV) of current ED chairs in departments with Accreditation Council for Graduate Medical Education (ACGME)‐accredited residency programs. Former women chairs were included due to paucity of current women chairs. Statistics were calculated using bivariate and multivariate analysis.ResultsOf 163 eligible chairs, 88 CV (54%) were obtained, including six former women chairs. A majority (86.4%) self‐identified as White/Caucasian, 21.5% were women, 46% were chief residents, 28.4% completed additional postgraduate degrees, and 21.8% were fellowship trained. At time of chair appointment, 58% were professor rank, 53.5% held ED operations roles, and 32% served as vice chair. Women were more likely to be in educational (53% vs. 22%) versus operational (26% vs. 61%, p = 0.02) roles. Women obtained more advanced degrees (47% vs. 25%, p = 0.02), were awarded more nonfederal grants (median = 7 vs. 3, p = 0.04), and achieved more national committee leadership (median = 4 vs. 1, p = 0.02). There were no gender differences in fellowship training, awards, leadership training programs, publications, federal grants, or national/international lectures after adjusting for years in practice.ConclusionWhile the majority of chairs held prior leadership roles in ED operations, only one in five women chairs did, suggesting gender differences in the path to chair attainment. These differences in paths may contribute to persistent gender disparities in ED chairs and may be influenced by career path choices, implicit bias, and structural barriers.

333 Background: Hepatitis B is a cause of hepatocellular carcinoma (HCC) globally, irrespective of viral loads. Interestingly, this process is not necessarily mediated through cirrhosis and may in fact involve oncogenic processes. Prior studies have suggested specific oncogenic gene expression pathways affected by viral regulatory proteins. Thus, identifying these genes and associated pathways could highlight predictive factors for HCC transformation, and has implications in early diagnosis and treatment. Methods: We employed our Search, Tag, Analyze, Resource (STARGEO) platform to conduct a meta-analysis of public data from NCBI's Gene Expression Omnibus. We performed meta-analysis consisting of 155 tumor samples compared against 185 adjacent non-tumor samples. We present the results from the meta-analysis in Ingenuity Pathway Analysis. Results:Our analysis revealed LXR/RXR activation, LPS-IL-1 mediation inhibition of RXR, and FXR/RXR activation as top canonical pathways amongst others. Top upstream regulators identified included the Ras family gene RABL6. The role of RABL6 in oncogenesis is beginning to unfold but its specific role in HBV-related HCC remains undefined. Our causal analysis suggests RABL6 mediates pathogenesis of HBV-related HCC through promotion of genes related to cell division, epigenetic regulation, and Akt signaling. Additionally, HOXA10 was a top upstream regulator and was strongly upregulated in our analysis. While described in other cancer, HOXA10 has not been well documented in HBV-related HCC and our causal analysis suggests it mediates pathogenesis through downregulation of tumor suppressors and its protective effect from oxidative stress. Conclusions: This meta-analysis describes possible role of viral regulatory proteins such as RABL6 and HOXA10 in the pathogenesis of HBV -related HCC. Further prospective studies are needed to confirm our findings.

Objective: The aim of this work is to formulate recommendations based on global expert consensus to guide the surgical community on the safe resumption of surgical and endoscopic activities. Background: The COVID-19 pandemic has caused marked disruptions in the delivery of surgical care worldwide. A thoughtful, structured approach to resuming surgical services is necessary as the impact of COVID-19 becomes better controlled. The Coronavirus Global Surgical Collaborative sought to formulate, through rigorous scientific methodology, consensus-based recommendations in collaboration with a multidisciplinary group of international experts and policymakers. Methods: Recommendations were developed following a Delphi process. Domain topics were formulated and subsequently subdivided into questions pertinent to different aspects of surgical care in the COVID-19 crisis. Forty-four experts from 15 countries across 4 continents drafted statements based on the specific questions. Anonymous Delphi voting on the statements was performed in 2 rounds, as well as in a telepresence meeting. Results: One hundred statements were formulated across 10 domains. The statements addressed terminology, impact on procedural services, patient/staff safety, managing a backlog of surgeries, methods to restart and sustain surgical services, education, and research. Eighty-three of the statements were approved during the first round of Delphi voting, and 11 during the second round. A final telepresence meeting and discussion yielded acceptance of 5 other statements. Conclusions: The Delphi process resulted in 99 recommendations. These consensus statements provide expert guidance, based on scientific methodology, for the safe resumption of surgical activities during the COVID-19 pandemic.

Introduction: Patients with D-TGA palliated with atrial switch operations have the morphologic right ventricle in the systemic position. There is increased risk of atrial arrhythmias and systemic right ventricle (SRV) failure. We sought to analyze the long term outcomes of these patients. Methods: All patients with D-TGA and SRV followed in the Adult Congenital Heart Disease Clinic of a large tertiary care institution were reviewed. A comprehensive retrospective analysis of the medical record was performed, including consult notes, ECGs, echocardiograms and electrophysiology reports. Results: A total of 154 patients (63% male) aged 29±11 years were followed for a mean of 10±9 years (range 0-51). During follow-up, 3 patients underwent cardiac transplantation and 15 died; 5 had sudden death, 2 had cardiogenic shock, 5 had non-cardiac death (i.e., infective endocarditis, sepsis) and 3 had unknown causes of death. Heart failure symptoms were present in 53(34%) patients. Severe SRV systolic dysfunction occurred in 37(24%) patients, with a mean EF of 23±5.5%; moderate SRV dysfunction occurred in 67(44%) patients, mean EF 35±4%. Sinus node dysfunction was present in 75(49%) patients, complete AV block in 9(5%) patients, and a pacemaker placed in 60(39%) patients, with cardiac resynchronization therapy in 5. Atrial arrhythmias occurred in 94(61%) patients and ablations were performed in 47(31%) patients. An ICD was implanted in 37 patients; 5 patients had appropriate shocks, but 7 had inappropriate shocks due to atrial arrhythmias. Age (HR 1.07, p=001), heart failure symptoms (HR 4.9, p= 0.007), severe SRV enlargement (HR 3.7, p=0.03), severe systolic dysfunction (HR 5.4, p=0.003), severe systemic AV valve regurgitation (HR 5.2, p=0.002) and a QRS duration> 122ms (HR 3.7, p=0.02) were significant predictors of mortality. The 15 year probability of sudden death was 3.2%(95% CI 0-6.9%). Conclusions: Atrial arrhythmias are common after atrial switch operations secondary to atriotomy scars. Further studies will need to determine whether restoration of sinus rhythm or cardiac synchrony may prevent further deterioration of the systemic right ventricle. Severe SRV dysfunction and prolonged QRS duration >122ms were significantly correlated with mortality.

The excess intake of dietary sodium is a key modifiable factor for reducing disease progression in autosomal dominant polycystic kidney disease (ADPKD). The aim of this study was to test the hypothesis that the scored salt questionnaire (SSQ; a frequency questionnaire of nine sodium-rich food types) is a valid instrument to identify high dietary salt intake in ADPKD. The performance of the SSQ was evaluated in adults with ADPKD with an estimated glomerular filtration rate (eGFR) ≥ 30 mL/min/1.73 m2 during the screening visit of the PREVENT-ADPKD trial. High dietary sodium intake (HSI) was defined by a mean 24-h urinary sodium excretion ≥ 100 mmol/day from two collections. The median 24-h urine sodium excretion was 132 mmol/day (IQR: 112–172 mmol/d) (n = 75; mean age: 44.6 ± 11.5 years old; 53% female), and HSI (86.7% of total) was associated with male gender and higher BMI and systolic blood pressure (p < 0.05). The SSQ score (73 ± 23; mean ± SD) was weakly correlated with log10 24-h urine sodium excretion (r = 0.29, p = 0.01). Receiving operating characteristic analysis showed that the optimal cut-off point in predicting HSI was an SSQ score of 74 (area under the curve 0.79; sensitivity 61.5%; specificity 90.0%; p < 0.01). The evaluation of the SSQ in participants with a BMI ≥ 25 (n = 46) improved the sensitivity (100%) and the specificity (100%). Consumers with an SSQ score ≥ 74 (n = 41) had higher relative percentage intake of processed meats/seafood and flavourings added to cooking (p < 0.05). In conclusion, the SSQ is a valid tool for identifying high dietary salt intake in ADPKD but its value proposition (over 24-h urinary sodium measurement) is that it may provide consumers and their healthcare providers with insight into the potential origin of sodium-rich food sources.

AbstractBackgroundMultiple mononeuropathy is a rare presentation of primary (AL) amyloidosis and nerve biopsy is usually needed for diagnosis. Conventional imaging is useful to identify proximal nerve involvement but may be inadequate. We report a patient with multiple mononeuropathy whose presentation was suggestive of AL amyloid neuropathy and in whom repeated tissue biopsies were negative for amyloid (including two sensory nerves and one muscle).MethodsThe patient underwent magnetic resonance imaging (MRI) and whole body 18F‐florbetapir positron emission tomography (PET)/MRI.ResultsWhole body 18F‐florbetapir PET/MRI revealed abnormal low‐level florbetapir uptake in the right proximal tibial and peroneal nerves, which provided a target for a sciatic bifurcation fascicular nerve biopsy that was diagnostic of AL amyloidosis.Conclusions 18F‐florbetapir PET/MRI imaging is a promising diagnostic tool for patients with suspected peripheral nerve amyloidosis (including multiple mononeuropathy) in whom conventional imaging and nerve and muscle biopsies miss the pathology.

AbstractThe functional lumen imaging probe (FLIP) is a diagnostic tool that utilizes impedance planimetry to allow the assessment of luminal diameter and distensibility. It has been used primarily in esophageal diseases, in particular, in the assessment of achalasia, esophagogastric junction outflow obstruction, and eosinophilic esophagitis (EoE). The usage and publications have increased over the past decade and it is now an essential tool in the armamentarium of the esophagologist. Indications are emerging outside of the esophagus, in particular with regard to gastroparesis. Our paper will review the history of FLIP, optimal current usage, data for key esophageal disorders (including achalasia, reflux, and EoE), data for nonesophageal disorders, and our sense as to whether FLIP is ready for prime time, as well as gaps in evidence and suggestions for future research.

9592 Background: Palliative care (PC) is an essential part of the continuum of care for cancer (CA) patients (pts). Little is known about the aggregate characteristics and survival of pts receiving inpatient palliative care consultation (PCC). Methods: We reviewed data prospectively collected on patients seen by the Palliative Care Inpatient Consult Service at Mayo Clinic - Rochester from 2003–2008. Demographics, consult characteristics, and survival were analyzed. Kaplan-Meier survival curves and a Cox model of survival were produced. Results: 1794 total patients were seen over the five year period. Cancer is the most common primary diagnosis (47%). Growth in annual PCC has risen dramatically (113 in 2003 vs. 414 in 2007) despite stable total hospital admissions. Patient are predominantly men (52% vs. 48%, p=0.02); median age is 76. General medicine, medical cardiology, and medical intensive care unit services refer most often. Most frequent issues addressed are goals of care, dismissal planning, and pain control (29%, 19%, 17%). PCC in actively dying pts have increased with 27% of all non-operating room, non-trauma in-hospital deaths being seen. Although CA pts have the highest median survival after PCC vs. other diagnoses (17 days, p = 0.018), we observed a five-year trend of decreasing survival from admission to death and PCC to death. Median time from admission to death in CA pts is 36 days in 2003 and 19 days in 2008 (p<0.01). Median time from PCC to death is 33 versus 11.5 days (p<0.01). Despite this, median hospital length of stay and time from PCC to discharge have remained fixed at 8 and 2.5 days, respectively. A Cox model of survival to discharge and <6 months survival (hospice eligibility) shows hospital length of stay, time from consult to discharge, and dismissal location from hospital are all prognostic factors. Conclusions: Survival window for PC intervention for CA pts is lessening. With the trend of shorter survival after PCC, PC professionals have little over two days to implement a comprehensive, ongoing care plan. This highlights the importance of earlier outpatient palliative care involvement with advanced cancer patients and families. No significant financial relationships to disclose.

Abstract ObjectiveThis study aims to determine the role of personal protective measures in the prevention of COVID-19 spread among the physicians working at different health facilities in Bangladesh.MethodsThis hospital-based cross-sectional comparative was conducted from May to June 2020. A total of 98 COVID-19 positive physicians and 92 COVID-19 negative physicians (physicians having no symptoms of COVID-19 or tested negative), were enrolled. The questionnaire was adapted from a tool developed by the World Health Organization (WHO) for risk assessment and management of exposure of health care workers in the context of COVID-19. Data was collected from the respondents online using google forms.ResultsThere was no significant difference in baseline information between COVID-19 positive and COVID-19 negative physicians. The physicians, who were unaware of direct participation in COVID-19 patient care, had higher odds of being COVID-19 positive (OR= 4.018; CI: 1.532-10.535). Also, the physicians, who were unaware of the COVID-19 status while performing aerosol generated procedure (AGP), had a higher chance of being COVID-19 positive, had a higher chance of being COVID-19 positive (OR= 2.522; CI: 1.020-6.233). Using face shields/goggles (OR=0.437; CI:0.228-0.837), regular decontamination of the patient’s surroundings (OR=0.392; CI:0.176-0.873) while usual take care of patients and use of N95 masks while performing AGP (OR=0.372; CI:0.159-0.873) had protective roles against COVID-19 among the physicians. The physicians who had reused the medical gown had two times more chance of being tested positive for COVID-19 than those who had not reused it (OR= 2.3; CI:1.251-4.259).ConclusionThe use of face shield/goggles and N95 masks and decontamination of the patient’s surroundings may give protection against COVID-19. Also, reusing medical gown should be avoided as much as possible.
