Goals: To develop an encounter decision aid [Barrett’s esophagus Choice (BE-Choice)] for patients and clinicians to engage in shared decision making (SDM) for management of BE with low-grade dysplasia (BE-LGD) and assess its impact on patient-important outcomes. Background: Currently, there are 2 strategies for management of BE-LGD—endoscopic surveillance and ablation. SDM can help patients decide on their preferred management option. Study: Phase-I: Patients and clinicians were engaged in a user-centered design approach to develop BE-Choice. Phase-I included review of evidence on BE-LGD management, observation of usual care (UC), creation, field-testing, and iterative development of BE-Choice in clinical settings. Phase-II: Impact of BE-Choice on patient-important outcomes (patient knowledge, decisional conflict, and patient involvement in decision making) was assessed using a controlled before-after study design (UC vs. BE-Choice). Results: Phase-I: Initial prototype was designed with observation of 8 clinical encounters. With field-testing, 3 successive iterations were made before finalizing BE-Choice. BE-Choice was paper based and fulfilled the qualifying criteria of International patient decision aid standards. Phase II: 29 patients were enrolled, 8 to UC and 21 to BE-Choice. Compared with UC, use of BE-Choice improved patient knowledge (90.4% vs. 70.5%; P =0.03), decisional comfort (89.6 vs. 71.9; P =0.01), and patient involvement (OPTION score: 27.1 vs. 19.2; P =0.01). Conclusions: BE-Choice is a feasible and effective decision aid to promote SDM in the management of BE-LGD. On pilot testing, BE-Choice had promising impact on patient-important outcomes. A larger multicenter trial is needed to confirm our results and promote widespread use of BE-Choice.

SummarySickle cell disease (SCD) has a distinct pattern of transfusional iron overload (IO) when compared to transfusion‐dependent β‐thalassaemia major (TDT). We conducted a single institution prospective study to evaluate plasma biomarkers of iron regulation and inflammation in patients with SCD with IO (SCD IO cases, n = 22) and without IO (SCD non‐IO cases, n = 11), and non‐SCD controls (n = 13). Hepcidin was found to be inappropriately low, as evidenced by a significantly higher median hepcidin/ferritin ratio in non‐SCD controls compared to SCD IO cases (0·3 vs. 0·02, P < 0·0001) and SCD non‐IO cases (0·3 vs. 0·02, P < 0·0001), suggesting that certain inhibitory mechanism (s) work to suppress hepcidin in SCD. As opposed to the SCD non‐IO state, where hepcidin shows a strong significant positive correlation with ferritin (Spearman ρ = 0·7, P = 0·02), this correlation was lost when IO occurs (Spearman ρ = −0·2, P = 0·4). Although a direct non‐linear correlation between erythroferrone (ERFE) and hepcidin did not reach statistical significance both in the IO (Spearman ρ = −0·4, P = 0·08) and non‐IO state (Spearman ρ = −0·6, P = 0·07), patients with highest ERFE had low hepcidin levels, suggesting that ERFE contributes to hepcidin regulation in some patients. Our results suggest a multifactorial mechanism of hepcidin regulation in SCD.

Introduction We assessed patients’ perceptions of physician empathy during telemedicine consultations as compared to in-person consultations during clinical encounters for acute stroke. Methods This prospective cohort study was undertaken at a comprehensive stroke centre hub in collaboration with a distant community hospital spoke site. Eligible participants presented to hub or spoke emergency departments with suspected acute stroke within three hours of symptom onset. Participants were evaluated at the hub site in person or at the remote site via telemedicine by the same group of neurologists. Following acute care decisions, single-visit data including participant-reported assessments of physician empathy were collected within 24 h. The primary outcome was the Consultation and Relational Empathy score. The secondary outcome for the telemedicine cohort was the Telemedicine Patient Satisfaction Measure score. Results Between 31 May 2013–13 March 2019, 70 patients completed the study. Fifty patients were seen by telemedicine and 20 patients were seen in person. Median Consultation and Relational Empathy scores (with a possible score of 10–50) were 49 (range 27–50) for telemedicine and 45 (range 26–50) for in-person consultations (Wilcoxon rank sum p = 0.18). Each item of the Consultation and Relational Empathy questionnaire was rated very good or excellent by at least 87% of participants in the telemedicine group. The median Telemedicine Patient Satisfaction Measure score was 54 (range 12–60), with each item rated agree or strongly agree by at least 84% of participants. Discussion We found no difference between telemedicine and in-person visits in patient perception of physician empathy in acute stroke care. Therefore, we conclude that empathy can be conveyed by facial expression, voice and attentiveness in a telemedicine encounter and, in the setting of acute stroke care, does not require physical touch or proximity.

ObjectivesTo assess the outcomes of abdominal dermal‐fat grafting following superficial and total parotidectomy.MethodsA retrospective chart review of parotidectomy patients was performed. Patients were divided into four groups based on surgical extent and grafting status: superficial parotidectomy (SP), superficial parotidectomy with grafting (SPg), total parotidectomy (TP), and total parotidectomy with grafting (TPg). Complication rates and operative times were then compared between surgically matched groups (SP vs. SPg, TP vs. TPg). Complications included graft necrosis, gustatory sweating, first‐bite syndrome, infection, hematoma, sialocele, and seroma. Data was analyzed via chi‐square and two‐sample t testing, logistic regression, and one‐way analysis of variance.ResultsThe cohort consisted of 330 patients: 106 SP (32.12%), 61 SPg (18.48%), 82 TP (24.85%), and 81 TPg (24.55%). No donor site complications occurred. TPg resulted in seven graft necroses (8.64%), and 22 reported gustatory sweating (27.20% vs. 10 TP patients (12.2%), P = 0.016); SPg resulted in two necroses (3.28%). There were no other statistically significant differences in complication rates. Graft recipients receiving adjuvant radiation were more likely to develop necrosis (odds ratio [OR] 4.60, 95% confidence interval [CI], 1.16–18.27, P = .0194). Patients who developed gustatory sweating were 8.38 years younger (95% CI 2.66–14.10, P = 0.002, follow‐up time > 48 days). Grafting did not increase operative times (TP/TPg: mean = 275.91/263.65 minutes, standard error of the mean = 41.96/33.75, P = 0.822).ConclusionAn abdominal dermal‐fat graft is an excellent reconstructive choice for a parotidectomy defect and is not associated with increased complication rates or prolonged operative time.Level of Evidence4 Laryngoscope, 130:2144–2147, 2020

Because of the rising incidence and lethality of esophageal adenocarcinoma, Barrett's esophagus (BE) is an increasingly important premalignant target for cancer prevention. BE-associated neoplasia can be safely and effectively treated with endoscopic eradication therapy (EET), incorporating tissue resection and ablation. Because EET has proliferated, managing patients after complete eradication of intestinal metaplasia has taken on increasing importance. Recurrence after complete eradication of intestinal metaplasia occurs in 8%–10% of the patients yearly, and the incidence may remain constant over time. Most recurrences occur at the gastroesophageal junction, whereas those in the tubular esophagus are endoscopically visible and distally located. A simplified biopsy protocol limited to the distal aspect of the BE segment, in addition to gastroesophageal junction sampling, may enhance efficiency and cost without significantly reducing recurrence detection. Similarly, research suggests that current surveillance intervals may be excessively frequent, failing to reflect the cancer risk reduction of EET. If validated, longer surveillance intervals could reduce the burden of resource-intensive endoscopic surveillance. Several important questions in post-EET management remain unanswered, including surveillance duration, the significance of gastric cardia intestinal metaplasia, and the role of advanced imaging and nonendoscopic sampling techniques in detecting recurrence. These merit further research to enhance quality of care and promote a more evidence-based approach.

Background: With increasing demand for neurologists, nontraditional health care delivery mechanisms have been developed to leverage this limited resource. Introduction: Telemedicine has emerged as an effective digital solution. Over the past three decades, telemedicine use has steadily grown; however, neurologists often learn on the job, rather than as part of their medical training. The current literature regarding telestroke training during neurology training is sparse, focusing on cerebrovascular fellowship curricula. We sought to enhance telestroke training in our neurology residency by incorporating real-life application. Materials and Methods: We implemented a formal educational model for neurology residents to use telemedicine for remote acquisition of the National Institutes of Health Stroke Scale (NIHSS) for patients with suspected acute ischemic stroke (AIS) before arrival at our comprehensive stroke center. This three-phase educational model involved multidisciplinary classroom didactics, simulation exercises, and real-world experience. Training and feedback were provided by neurologists experienced in telemedicine. Results: All residents completed formal training in telemedicine prehospital NIHSS acquisition and had the opportunity to participate in additional simulation exercises. Currently, residents are gaining additional experience by performing prehospital NIHSS acquisition for patients in whom AIS is suspected. Our preliminary data indicate that resident video encounters average 10.6 min in duration, thus saving time once patients arrive at our hospital. Discussion: To our knowledge, this is the first report of a telestroke-integrated neurology residency program in a comprehensive stroke center resulting in shortened time to treatment in patients with suspected AIS. Conclusions: We present a model that can be adopted by other neurology residency programs as it provides real-world telemedicine training critical to future neurologists.

Objective Volumetric laser endomicroscopy (VLE) is an advanced imaging modality used in Barrett’s oesophagus (BE) to help identify dysplasia in the oesophagus. VLE criteria exist for oesophageal dysplasia but not for dysplasia in the gastric cardia. The aim of this study was to determine if there are in vivo VLE features that can predict gastric cardia dysplasia in BE. Design This was a single-centre observational cohort study from August 2016 to August 2018. Patients were included if they had BE, were undergoing a VLE exam as standard of care, and had a suspicious target laser marked at the gastric cardia. The following VLE features were correlated to histology to determine if an association existed between histology subtype and VLE feature: wide crypts, irregular surface, one large isolated gland, multiple glands, and complex glands. Results A total of 110 in vivo gastric cardia targets in 77 patients with BE were analysed. The following abnormalities were identified: 61 wide crypts, 34 isolated glands, 16 irregular surfaces, 15 multiple glands, and 11 complex glands. Complex glands were the only VLE feature that correlated to any histology subtype. They were present in 71% of targets with high-grade dysplasia (HGD), T1a cancer or T1b cancer and had a sensitivity, specificity, and accuracy of 71%, 99%, and 85%, respectively. Of the 10 patients with complex glands on VLE and HGD/cancer on histology, 4 had a normal-appearing mucosa (40%) on endoscopy. Conclusion Identification of complex glands on VLE may aid in detection of HGD or early cancer in the gastric cardia in BE. This is particularly important, as dysplasia at the gastric cardia can be difficult to see endoscopically.

Abstract Background: Recent reports from the thalassemia literature suggest that serum ferritin may be a poor and possibly misleading measure of total iron store in heavily iron overloaded patients. Moreover, the relationship between plasma ferritin and body iron stores is distorted by ascorbate deficiency, fever, infection, inflammation, and hepatic dysfunction, all of which occur in patients with sickle cell disease (SCD). On the other hand, following the results of multiple studies that demonstrated a high correlation of hepatic iron overload determination by magnetic resonance imaging to the values found in specimens from liver biopsy, R2* liver MRI has emerged as the best noninvasive yet highly sensitive and specific method for measuring the level of iron in the liver. The goal of this study was to determine the correlation of liver iron by liver R2* MRI with serum ferritin and by extrapolation assess whether serum ferritin remains to be a useful clinical marker of iron overload in patients with SCD. We also sought to determine the correlation of liver iron concentration with abnormalities in the liver function tests. Methods: We conducted a retrospective analysis of 31 patients with sickle cell disease and transfusional iron overload who are being followed at the Augusta University Comprehensive Sickle Cell Center. Serum ferritin, hepatic R2* MRI liver iron concentration, hepcidin level, and liver function tests (AST, ALT and total bilirubin) were assessed for correlation. We used the Pearson correlation coefficient to determine the relationship between the various variables with hepatic R2* MRI. Results: Serum ferritin levels showed a statistically significant positive correlation with R2* hepatic MRI (r = 0.479 with p = 0.0085) in the patients with SCD and transfusional iron overload . We also saw a positive correlation, although not statistically significant, between hepcidin level and liver iron concentration by liver MRI(r=0.493 with P= 0.399). This may be due to the small sample size of the patients who had hepcidin levels available. On the other hand, no correlation was detected between abnormalities in liver function tests and liver iron concentration. The correlation between liver iron concentration(LIC) and AST was 0.045 with p = 0.816 and the correlation between LIC and ALT was 0.233 with p = 0.224. Conclusion: While R2* MRI is the the most accurate method to diagnose and monitor response to therapy in SCD patients with transfusional iron overload, we have found a statistically significant positive correlation with serum ferritin values. Thus, where R2* liver MRI is unavailable, serum ferritin remains a clinically useful tool that can be used in the diagnosis and monitoring of iron overload in sickle cell patients, despite its limitations. As previously reported, we did not find any correlation between LIC and liver function abnormalities in this population (Harmatz et al, 2000) These findings suggest that patients with SCD may have a different response to iron overload in comparison to patients with thalassemia or hereditary hemochromatosis.

Abstract Abstract 94 Background: Lymphoma diagnosed during pregnancy is a rare occurrence. Further, there is heterogeneity in clinical presentation and a range of lymphoma histologies resulting in a continued deficiency of lymphoma-specific data in the literature regarding prognosis, optimal therapy, maternal complications, and fetal outcome. Methods: A comprehensive retrospective analysis was completed for patients (pts) diagnosed (dx) with Hodgkin lymphoma (HL) or non-Hodgkin lymphoma (NHL) during pregnancy at 9 large U.S. academic centers over a 13-year period (1998–2011). The vast majority of cases were co-managed with high-risk maternal fetal medicine. Data on maternal disease characteristics, treatment details, obstetric complications, and fetal outcomes were analyzed. Results: 88 cases were identified with complete data available in 82. The median age of pts was 31 yrs (18–40). Lymphoma dx occurred at a median of 24 weeks (wks) gestation (5–40). 15% of pts were dx during the 1st trimester, 46% during the 2nd trimester, 35% during the 3rd trimester, while 4% (n=3) of pts had a pre-existing NHL dx (follicular lymphoma (FL)). 52% (n=43) of pts had NHL and 48% (n=39) HL. Of NHL cases, 83% (n=33) were B-cell and 17% (n=10) T-cell. B-cell histologies were DLBCL n=23 (including 2 primary CNS and 1 'double hit' NHL), FL n=5 (including 1 leukemic phase FL), Burkitt's lymphoma n=3, and mixed histology n=1; T-cell histologies were anaplastic large cell n=6, PTCL not otherwise specified n=2, and T-cell/NK NHL n=2. Pts with B-cell NHL and HL were dx at a median age of 29 yrs (range, 18–40), while T-cell NHL pts were dx at a median of 34 years (19–37). MRI without gadolinium was the most common imaging modality utilized for staging. 63% of NHL and 19% of HL pts had stage III/IV disease (25% of HL with stage IIB). Pregnancy was terminated in 6 pts (n=4 aggressive NHL and n=2 HD) to enable immediate chemotherapy (five in the 1st trimester [at 5, 8, 10, 10, and 12 wks] and 1 pt in the early 2nd trimester who required high-dose methotrexate). 48 pts (63%) initiated anti-lymphoma therapy at a median of 25 wks gestation (range, 13–37) with 79% of pts initiating therapy in the 2nd trimester (see Table 1). The median gestation at time of lymphoma dx for pts who received intra-partum treatment was 20 wks vs 34 wks for pts who had therapy deferred to post-delivery (p<0.0001). The overall response rate among pts who received therapy was 87% (74% complete remission). Notably, gestation went to full-term in 54% with delivery occurring at a median of 37 wks (31–40). Therapy was deferred until post-delivery in 28 pts (37%) and the majority of these pregnancies were also carried to term (median delivery at 38 wks). At a median follow-up of 41 months (6–157), the 3-year PFS and OS for all pts were 79% and 89% respectively. Histology-specific 3-year PFS and OS were: B-cell NHL: 73% and 82%, respectively; T-cell NHL: 50% and 90%, respectively; and HL: 90% and 95%, respectively (Figure 1). Detailed obstetrical information was available in 59 pts. There were minimal pre-term complications, the most common being induction of labor in 45%. Perinatal events included spontaneous rupture of membranes in 5% and pre-eclampsia in 8%. Further, there were no differences in these events detected among pts who received intra-partum treatment vs deferred therapy. No episodes of chorioamnionitis or endometritis were noted. There was 1 stillbirth that occurred at 19 wks gestation in a 34-year-old pt with double-hit NHL following 1 cycle of R-CHOP. The median birth weight of infants was 2427 grams (1005–5262) with no difference among pts who received intra-partum chemotherapy vs not (2637 grams vs 2212 grams, respectively; p=NS). Microcephaly was reported in 1 case following 4 intra-partum cycles of CHOP for DLBCL; there were otherwise no malformations detected. Conclusions: To our knowledge, this represents one of the largest experiences reported of lymphoma in pregnancy. Our data show that standard NHL and HL chemotherapeutic regimens (without anti-metabolites) administered during the 2nd and 3rd trimester, including as early as 13 wks gestation in select cases, is associated with minimal maternal complications or fetal detriment. In addition, pts with low risk clinical scenarios (e.g., indolent NHL and/or late gestational dx) had therapy safely deferred to post-partum. In our experience, this approach was associated with overall expected lymphoma-related survival. Disclosures: No relevant conflicts of interest to declare.
