69 Background: Healthcare organizations can cultivate the strength of a diverse workforce in creating a culture of excellence. Enabling the team to understand how personal and cultural beliefs affect our decision making and how we interact with patients and colleagues is integral. Gaps in care exist in cancer diagnoses and treatment in many minority groups. A need for education in the nature of assumptions, unconscious biases, and awareness around the existence of healthcare disparities, was identified through culture transformation work within multiple healthcare institutions. Methods: An experiential course was designed for multi-disciplinary groups of providers. Designed to meet the evolving demographics in the country and help participants recognize how their own cultural beliefs and values affect their decision making. Topics include cultural awareness, assumptions and unconscious bias, effective use of interpreters, and skills to recognize when cultural differences may be playing a role and how to successfully navigate these situations. Raising awareness of healthcare disparities is highlighted, including disparities in cancer care diagnosis, treatment and outcomes for different ethnicities and socioeconomic groups. Examples include disparities in diagnosis, treatment and outcomes of lung cancer, colon cancer and breast cancer in minorities. Results: Participants engage in skills-based work. Participants develop a plan how they can take this information and education back to help create an awareness of disparities and skills to successfully navigate these situations. After this program, participants will be cognizant of the nature of assumptions and unconscious bias and understand the strength of diversity as an asset rather than a hindrance. Conclusions: Healthcare disparities can have a significant impact on patient experience, quality and outcomes. Specific inequities in cancer diagnosis and treatment in minorities is highlighted. Participants are provided with information and skills that can be introduced to their home institutions to have all caregivers recognize and successfully navigate culturally sensitive situations.

AbstractObjectiveWhile prior Epstein–Barr virus (EBV) infection has been consistently associated with subsequent risk of developing multiple sclerosis (MS), the association with other common herpesviruses has been more controversial. Our objectives were to determine whether remote infection with EBV and other common herpesviruses affect the susceptibility to pediatric MS and if there are interactions between genetic and demographic factors and viral infections.MethodsCases with pediatric‐onset MS or clinically isolated syndrome within 4 years of disease onset, and controls were recruited from 16 American pediatric MS centers. Logistic regression models adjusted for potential confounders assessed the association between case status and serological evidence for past infection with EBV, cytomegalovirus (CMV), Herpes Simplex viruses‐1 (HSV‐1) and ‐2. We determined the heterogeneity of the effect of viral infection on the risk of having MS according to race, ethnicity and HLA‐DRB1:1501 status.ResultsA total of 356 pediatric cases and 493 controls were recruited. In multivariable models, EBV‐viral capsid antigen (VCA) seropositivity was associated with increased odds of having MS by 7.4 times (95% CI: 4.5–12.0, P < 0.001). Seropositivity for HSV‐1 was also associated with increased odds of having MS (OR 1.54, 95% CI: 1.06–2.25, P = 0.025) but this increase was seen only in Whites (OR = 2.18, 95% CI 1.35–3.52, P < 0.001) and those negative for HLA‐DRB1*1501 (OR = 1.89, 95% CI 1.17–3.03, P = 0.009). The effect of remote EBV infection on the risk of pediatric MS depended on race and HLA‐DRB1*15:01 status.InterpretationEBV seropositivity is strongly associated with pediatric MS, as is HSV‐1 seropositivity in subjects negative for HLA‐DRB1*15:01. Our report of interactions between select viral exposures, and age, race and DRB1 status suggests a complex effect of environmental and genetic risk factors on MS development.

AbstractT‐lymphoblastic leukemia/lymphoma (T‐ALL/LBL) accounts for approximately 15% of pediatric and 25% of adult ALL. While the underlying frequency of KMT2A (MLL) gene rearrangements has been identified in approximately 4‐8% of T‐ALL/LBL cases, a paucity of literature is available to characterize further the KMT2A rearrangements in pediatric/young adult T‐ALL/LBL. A 10‐year retrospective review was performed to identify KMT2A rearrangements in specimens sent for T‐ALL/LBL fluorescence in situ hybridization studies in patients under the age of 30 years. Of 806 T‐ALL/LBL FISH studies performed on unique individuals, 27 (3.3%) harbored KMT2A rearrangements. Nineteen patients were male and eight were female (M:F ratio, 2.4:1) with ages ranging from 1 to 20 years (mean 12, median 12). Of the 27 cases, nine (33%) had KMT2A/MLLT1 fusions, eight (30%) had KMT2A/AFDN fusions, two (7%) had KMT2A/ELL fusions, and one (4%) had a KMT2A/MLLT10 fusion. In addition, five (19%) had KMT2A rearrangements with unidentified gene fusion partners and two (7%) had 3’KMT2A deletions. Our results indicate that MLLT1 and AFDN account for the majority (63%) of KMT2A gene partners in pediatric/young adult T‐ALL/LBL, while no KMT2A/AFF1 or KMT2A/MLLT3 fusions were observed despite their common identification in B‐ALL and acute myeloid leukemia, respectively. In addition to diagnostic and prognostic value, detecting specific KMT2A fusions may also be of clinical importance in the era of targeted therapies.

International normalized ratio (INR) measurements manage risks of bleeding and clotting sequelae in the population with left ventricular assist device (LVAD). Studies suggest that point-of-care (POC) INR does not significantly differ from plasma INR (P-INR) values in other patient populations, although this has not been validated in a multicenter LVAD study. We sought to determine whether POC-INR and P-INR values differ significantly in the LVAD population and reviewed patients with permanent LVAD implantation at seven institutions internationally. Our cohort comprised of 279 paired POC-INR and P-INR checks in patients supported on average 630 ± 598 days postimplant with predominately HeartWare, HeartMate II, and HeartMate III devices. The population averaged 57.9 years of age, and there were 86.7% male. We found no statistically significant difference between POC-INR and P-INR values. International normalized ratio accuracy correlated weakly with the time between INR measurements (p < 0.001). When the time difference was less than 4 hours, the difference between INR pairs was significantly lower than measurements greater than 8 hours (p = 0.006). There was no statistically significant difference when comparing paired INR values and time after implant to INR check (p = 0.43), age (p = 0.12), known coagulopathy (p = 0.12), bleeding history (p = 0.22), or thrombosis history (p = 0.34). This is the first large multicenter international study comparing POC-INR and P-INR measurements in patients with LVAD and found no statistically significant difference between either methods, particularly when measured within less than 4 hours of each other.

e21704 Background: Patients with myeloproliferative neoplasms (MPN) have difficult symptom burden (i.e. fatigue, pruritus, night sweats) not resolved by current medical therapies including jak inhibitor therapy. We hypothesize that on-line (at home) yoga might alleviate MPN symptoms and complement medical therapy. Methods: MPN patients, recruited by social media, were asked to complete 60 min/week of online yoga (designed for MPN patients) for 12 weeks and completed online self-report surveys (weeks 0,7,12 and 16) on participation (Qualtrics), disease features, and symptom burden (MPN Symptom Assessment Form; NIH PROMIS measures of pain, anxiety, depression, sleep, and sexual function). Results: Two hundred and forty-four MPN patients completed the eligibility survey, 134 were eligible, 55 completed the informed consent, and 38 MPN patients completed the 12-week intervention. The majority of participants were diagnosed with either PV (n = 16) or ET (n = 16), with MF being less common (n = 6). Approximately 37% (n = 14) of study participants averaged ≥60 min/week of yoga (i.e., demand). Yoga participation averaged 50.8±36.2 min/week. Overall, 68% of participants were satisfied with online yoga and 75% felt that is was helpful for coping with MPN-related symptoms (i.e., acceptability, practicality). Additionally, 75% of participants felt safe from injury while participating in online yoga. Only one adverse event was reported (irritated enlarged spleen). From week 0 to week 12 (n = 38), there were significant improvements in total symptom burden (effect size [ES] in standard deviation units = -0.36, p = 0.004), anxiety (ES = -0.67, p = 0.002), depression (ES = -0.41, p = 0.049), sleep (ES = -0.58, p < 0.001), and fatigue (ES = -0.33, p = 0.04). These improvements remained significant at follow-up week 16 (n = 28) for all outcome measures with a trend for maintained fatigue improvement (ES = -0.34, p = 0.06) (see Table 1). There were no significant differences in outcomes between those that averaged < 60 min/week of yoga compared to those that averaged ≥60 min/week of yoga. Conclusions: A 12-week online yoga intervention is feasible (i.e., accepted, practical) for MPN patients and merits a randomized trial as complementary therapy.
