Abstract
BACKGROUND Impulse oscillometry (IOS) is an effective tool for assessing airway mechanics and diagnosing obstructive airway disease (OAD) in children with sickle cell disease (C-SCD). Obesity is known to be associated with OAD, and untreated OAD often leads to hypoxia-related complications in C-SCD. Considering the increasing prevalence of obesity in C-SCD, it is important to explore the influence of body mass index (BMI) on OAD in this disease population. METHODS A longitudinal retrospective chart review was conducted on 55 C-SCD (161 IOS observations) and 35 non-SCD asthmatic children (C-Asthma) (58 observations), primarily to investigate the association between BMI and airway resistance in C-SCD and C-Asthma. We conducted generalized linear mixed models (GLMM), adjusted for pharmacotherapies, to demonstrate the influence of BMI on total (R5), central (R20), and peripheral (R5-20) airway resistance and reactance (X5, resonant frequency (Fres)). We further compared age, BMI, and IOS indices between C-SCD and C-Asthma using the Mann-Whitney test. RESULTS Age and BMI were not statistically different between the two groups. In C-SCD, BMI was associated with R5 (GLMM t-statistics:3.75, 95%CI:1.01,3.27, p-value<0.001*) and R20 (t-statistics:4.01, 95%CI:1.04,1.15, p-value<0.001*), but not with R5-20 or airway reactance. In asthmatics, BMI was not associated with IOS estimates except Fres (t-statistics: 3.93, 95%CI: -0.06, -0.02, p-value<0.001*). C-SCD demonstrated higher airway resistances (R5 and R20) and reactance (Fres) compared to C-Asthma (Mann-Whitney: p-values<0.05). CONCLUSION BMI significantly influenced total and central airway resistance in C-SCD. While higher airway resistances reflected increased OAD in C-SCD than asthmatics, higher Fres perhaps indicated progressive pulmonary involvement in C-SCD.

Abstract
Developing a reproducible and secure supply of customizable control tissues that standardizes for the cell type, tissue architecture, and preanalytics of interest for usage in applications including diagnostic, prognostic, and predictive assays, is critical for improving our patient care and welfare. The conventionally adopted control tissues directly obtained from patients are not ideal because they oftentimes have different amounts of normal and neoplastic elements, differing cellularity, differing architecture, and unknown preanalytics, in addition to the limited supply availability and thus associated high costs. In this study, we demonstrated a strategy to stably produce tissue-mimics for diagnostics purposes by taking advantage of the three-dimensional (3D) bioprinting technology. Specifically, we take anaplastic lymphoma kinase-positive (Alk+) lung cancer as an example, where a micropore-forming bioink laden with tumor cells was combined with digital light processing-based bioprinting for developing native-like Alk+ lung cancer tissue-mimics with both structural and functional relevancy. It is anticipated that our proposed methodology will pave new avenues for both fields of tissue diagnostics and 3D bioprinting significantly expanding their capacities, scope, and sustainability.

Abstract
Abstract
INTRODUCTION
Limited migration of dendritic cell (DC) vaccines to draining lymph nodes (DLN) remains a major limitation to DC efficacy for malignant gliomas. Our prior work demonstrated that increased peripheral DC migration to DLN results in enhanced antitumor efficacy. Given this, we studied DC trafficking in mouse gliomas, the meningeal lymphatic vessel (MLV) system, and the draining cervical lymph nodes (CLN).
METHODS
To elevate host DC populations, C57BL/6 and VMDk mice were implanted with B16-FMS-like tyrosine kinase 3 ligand (FLT3L) melanoma or with B16-FLT3L supernatant. Mice were implanted intracranially with CT2A, GL261-OVA, and SMA560 syngeneic glioma lines in the right parietal lobe. Antitumor efficacy was measured by tumor weights and median overall survival (mOS).
RESULTS
DC injected into glioma hemispheres display delayed kinetics of peak migration to CLN compared to control (7 days (d) vs 3d post-injection (pi), respectively). Migration of intraventricular (ivn)-injected DC to CLN is superior at days 1, 3 and 7 pi when glioma is present (p = 0.026). B16-FLT3L supernatant results in a disproportionate systemic expansion in conventional type 1 over type 2 DC (cDC1 > cDC2) compared to media control (cDC1, cDC2 fold change over media for spleen = 27,11; DLN = 6,2; blood = 6,3). Pulsed dosing of FLT3L supernatant results in significantly greater numbers of splenic cDC1 compared to daily FLT3L dosing (p = 0.002). Mice with CT2A and continuous FLT3L secretion in vivo show longer survival (mOS 30d) compared to mice with continuous GM-CSF secretion (mOS 22d) (p = 0.009). Mice with SMA560 and FLT3L secretion have significantly reduced glioma growth compared to tumor alone, GM-CSF-secreting tumors, and mixed FLT3L/GM-CSF-secreting tumors (p = 0.029).
CONCLUSION
FLT3L signaling in vivo results in cDC1 > cDC2 generation and migration through the CNS with more favorable glioma efficacy. Modeling of DC migration through the glioma-MLV-CLN system with FLT3L stimulation permits testing of strategies to improve DC therapy.

Abstract
Abstract
INTRODUCTION
Chimeric antigen receptor (CAR) T cells specific for the glioblastoma (GBM)-specific epidermal growth factor receptor variant III (EGFRvIII; CARvIII) have successfully treated tumors homogeneously expressing EGFRvIII when combined with lymphodepletion, however this is not recapitulated clinically. We generated an “armored” CARvIII which constitutively secretes IL-12, a stimulatory cytokine that enhances T cell persistence and function, that is capable of treating orthotopic heterogeneous GBM in immune competent mice.
METHODS
C57Bl/6 mice were intracranially (IC) implanted with 5 x 105 of either homogenous (CT2AvIII) or heterogeneous (1:1 CT2AvIII and CT2A parental) tumor cells. Mice were treated with 2 x 106 CARvIII or IL-12 CARvIII seven days post tumor implant and monitored for survival. TCRα -/-, CD8-/- and C57Bl/6 mice were IC implanted with homogeneous or heterogeneous tumors and treated 7 days post implant with intracranial IL-12 CARvIII therapy to assess the role of endogenous T cells. T cells within the tumor microenvironment were characterized by flow cytometry days 8, 14, and 17 post tumor implantation.
RESULTS
IL-12 CARvIII cells were successfully generated, secreted IL-12, and were cytotoxic against EGFRvIII-expressing tumor cells in vitro. IL-12 CARvIII therapy was curative in homogenous CT2AvIII tumors (p< 0.0001) and conferred a long-term survival in 50% of mice with heterogeneous CT2AvIII:CT2A parental tumors in vivo (p< 0.0001). Furthermore, IL-12 CARvIII therapy successfully eradicated the homogeneous CT2AvIII tumors in TCRα -/- and CD8-/- mice but failed to produce any efficacy against the heterogeneous CT2AvIII:CT2A parental tumors (p=0.0002). Endogenous T cells in IL-12 CARvIII treated mice were found to be more migratory, and interestingly more exhausted than in CARvIII treated mice.
CONCLUSIONS
Our findings show that IL-12 CARvIII can effectively eradicate IC homogenous tumors without lymphodepletion. Surprisingly, IL12 CARvIII therapy also treated IC heterogeneous glioma. Heterogeneous tumor clearance required an endogenous CD8 T cell response.

Abstract
Abstract
BACKGROUND
Effective immunotherapy against tumors of the central nervous system (CNS) requires that the drug the blood brain barrier (BBB) and encounter immune cells. We have previously described a mechanism which may facilitate transport of CD3-engaging therapeutics into the CNS, via carriage on activated T cells. Building on this, we sought to produce specific T cell phenotypes that rapidly enter and accumulate in the CNS.
METHODS
8–10-week-old C57/Bl6 mice (n=5-6 per group) were implanted with 30,000 CT2AvIII cells which established over 14 days. Mice received (1) CD45.1 lymphocytes activated with IL-7 and Concanavalin-A (single intravenous (IV) injection, 1 x 107 adoptive lymphocyte transfer (ALT)) or (2) CD45.1 lymphocytes activated with IL-2 and serial Con-A stimulation. Mice were sacrificed 3 hours following ALT and their brains analysed via flow cytometry. A follow-up timepoint of 48 hours was also analysed. Groups were compared using a Mann-Whitney U test.
RESULTS
Ex vivo culture in group 1 yielded a mixed population of T effector and T central memory cells whereas group 2 resulted in terminally differentiated T effector memory cells only. VLA-4, a migratory integrin involved in T cell entry into the CNS was upregulated in the IL-7 group. Mice in Group 1 demonstrated significantly enhanced entry of CD8+ effector and memory T cells into tumor bearing hemispheres 3- and 48-hours following administration compared to Group 2 (p = 0.005, p = 0.0159 respectively).
CONCLUSIONS
Varying the cytokine cocktail used for ex vivo activation and expansion of T cells results in markedly different trafficking properties and phenotype composition. Ongoing work will determine how enhanced T cell localization to tumor affects accumulation of immunotherapy via the hitchhiking mechanism. Further, we will evaluate the safety of combinatorial CD3-engaging immunotherapy and ALT in Phase I trials (NCT04903795) using a cGMP Brain Bi-specific T cell engager (BRiTE).

Abstract
Patients with human epidermal growth factor receptor 2-positive (HER2+/ERBB2) breast cancer often present with brain metastasis. HER2-targeted therapies have not been successful to treat brain metastases in part due to poor blood-brain barrier (BBB) penetrance and emergence of resistance. Here, we report that Abelson (ABL) kinase allosteric inhibitors improve overall survival and impair HER2+ brain metastatic outgrowth in vivo. Mechanistically, ABL kinases phosphorylate the RNA-binding protein Y-box-binding protein 1 (YB-1). ABL kinase inhibition disrupts binding of YB-1 to the ERBB2 mRNA and impairs translation, leading to a profound decrease in HER2 protein levels. ABL-dependent tyrosine phosphorylation of YB-1 promotes HER2 translation. Notably, loss of YB-1 inhibits brain metastatic outgrowth and impairs expression of a subset of ABL-dependent brain metastatic targets. These data support a role for ABL kinases in the translational regulation of brain metastatic targets through YB-1 and offer a therapeutic target for HER2+ brain metastasis patients.

Abstract
BACKGROUND Total body irradiation in combination with melphalan for multiple myeloma (MM), was shown to be prohibitively toxic. To ameliorate toxicity, total marrow irradiation (TMI), was given as the sole ablative modality during the second cycle of tandem autologous stem cell transplant (TASCT) for MM patients on a phase I-II trial. STUDY DESIGN Patients with MM in response or with stable disease and ≤ 18 months from diagnosis received melphalan (MEL) 200 mg/m2 and ASCT (Cycle 1), and, after recovery, TMI and ASCT (Cycle 2) followed by maintenance with an IMiD and dexamethasone for up to 12 months. TMI doses were escalated from 1,000 cGy to 1,800 cGy by 200 cGy increments. RESULTS Fifty-four patients were to receive TASCT between 2004 and 2011; 8 patients received single ASCT due to patient or physician preference. The median time between melphalan and TMI was 65 days (range 47-125). Thirty patients (55•6%) received TASCT at the maximum tolerated dose of 1600 cGy. The complete and very good partial response rates were 48•1% and 22•2% following ASCT and maintenance. Median follow-up among survivors was 12.3 years (range: 9•2-15•5+). Progression free survival and overall survival at 10 years was 20•4% (95% CI 10•9-31•9) and 38•8% (95% CI: 25•9-51•5). Secondary neoplasms included (1 each) acute myeloid leukemia, papillary thyroid and prostate carcinoma, and melanoma, and we observed 1 case of ductal carcinoma in situ and 4 patients with non-melanoma skin cancers. CONCLUSION TMI as part of TASCT was well-tolerated and TASCT lead to a 20.4% PFS plateau. The inclusion of TMI as a conditioning regiment for MM prior to ASCT warrants further study in the context of modern induction and maintenance therapies.

Abstract
Objective We describe a structured approach to developing a standardized curriculum for surgical trainees in East, Central, and Southern Africa (ECSA). Summary Background Data Surgical education is essential to closing the surgical access gap in ECSA. Given its importance for surgical education, the development of a standardized curriculum was deemed necessary. Methods We utilized Kern's 6-step approach to curriculum development to design an online, modular, flipped-classroom surgical curriculum. Steps included global and targeted needs assessments, determination of goals and objectives, the establishment of educational strategies, implementation, and evaluation. Results Global needs assessment identified the development of a standardized curriculum as an essential next step in the growth of surgical education programs in ECSA. Targeted needs assessment of stakeholders found medical knowledge challenges, regulatory requirements, language variance, content gaps, expense and availability of resources, faculty numbers, and content delivery method to be factors to inform curriculum design. Goals emerged to increase uniformity and consistency in training, create contextually relevant material, incorporate best educational practices, reduce faculty burden, and ease content delivery and updates. Educational strategies centered on developing an online, flipped-classroom, modular curriculum emphasizing textual simplicity, multimedia components, and incorporation of active learning strategies. The implementation process involved establishing thematic topics and subtopics, the content of which was authored by regional surgeon educators and edited by content experts. Evaluation was performed by recording participation, soliciting user feedback, and evaluating scores on a certification examination. Conclusions We present the systematic design of a large-scale, context-relevant, data-driven surgical curriculum for the ECSA region.

Abstract
INTRODUCTION
Glioblastoma (GBM) is a lethal primary malignant brain tumor with a median survival of < 20 months. Our next generation immunotherapy utilizes chimeric antigen receptor (CAR) T cells targeted to GBM-specific overexpression of epidermal growth factor receptor variant III (EGFRvIII), “armored” with IL-12, a stimulatory cytokine that enhances T cell persistence and function, to treat orthotopic heterogeneous GBM.
METHODS
C57Bl/6 mice were intracranially implanted with 5 x 105 of either CT2AvIII tumor cells or a 1:1 mixture of CT2AvIII and CT2A parental tumor cells. Seven days post-implant, mice were treated with 2 x 106 IL-12 CARvIII and monitored for survival. For endogenous T cell activity assessment, TCRα -/- mice were intracranially implanted with either CT2AvIII cells or a 1:1 mixture of CT2AvIII:CT2A parental cells and treated 7 days post implant with intracranial IL-12 CARvIII therapy.
RESULTS
IL-12 CARvIII therapy was curative in the treatment of CT2AvIII homogeneous tumors and confers a long-term survival in 50% of CT2AvIII:CT2A mice. Furthermore, IL-12 CARvIII therapy successfully eradicated the homogeneous CT2AvIII tumors in TCRα-/- mice but failed to produce any efficacy against the heterogeneous CT2AvIII:CT2A parental tumors, suggesting that endogenous T cells are required for IL-12 CARvIII therapeutic success against heterogeneous tumors.
CONCLUSIONS
Our findings suggest that IL-12 CARvIII may be an effective treatment against heterogeneous glioma. Furthermore, this data provides insight on treatment against the immunosuppressive tumor microenvironment and applications against other solid tumors. In anticipation of translating this therapy into a phase I clinical trial, we are also investigating adjuvant therapies such irradiation to improve antitumor efficacy of IL-12 CARvIII against heterogeneous glioma.

Abstract
INTRODUCTION
The blood-brain barrier (BBB) restricts access to the central nervous system (CNS). Our brain bispecific T cell engager (hEGFRvIII:CD3 BRiTE) treats subcutaneous syngeneic tumor (CT2AvIII) but not intracranial CT2AvIII. CD3 engaging molecules such as nanoparticles can be carried into the brain by binding to activated T cells. We therefore sought to determine if co-administration of larger molecules (BRiTE, approx. 55kDa) with activated T cells could cross the BBB, enhancing survival.
METHODS
We implanted 8–10-week-old transgenic hCD3 mice (n=7-8 per group) with 30,000 CT2AvIII cells. Tumors were established for 6 days. Mice were administered either (1) autologous lymphocyte transfer (ALT) alone (single intravenous (IV) injection, 1 x 107 activated T cells), (2) serial IV BRiTE doses (50ug, 10 days) (3) BRiTE and ALT or (4) no treatment. Mice were followed for survival using Kaplan-Meier curves and compared via log rank test. Targeted mass spectroscopy analysis as well as PET/CT imaging of mice administered Iodine-124 radiolabelled BRiTE was performed to assess for intracranial accumulation.
RESULTS
Mice who received BRiTE and ALT demonstrated significantly enhanced survival compared to controls (median survival 29 vs 21 days, p=0.0135). Mice who received only BRiTE or ALT exhibited median survival comparable to controls (p=0.192, p=0.944 respectively). Mass spectroscopy analysis revealed that mice had a 7-fold increased peak area ratio of BRiTE in the CNS when co-treated with activated T cells compared to BRiTE alone (0.14, 0.02 respectively) while PET/CT imaging demonstrated increased radioactive signal over background localized to coordinates within the brain where tumors were injected.
CONCLUSIONS
Giving activated T cells alongside BRiTE allows better access to the intracranial compartment and is required to achieve efficacy in mice with syngeneic orthotopic glioma. Future work will determine the optimal dose and schedule for this approach, as well as defining the precise mechanism by which this occurs.

Abstract
OBJECTIVE To compare the effect of surgical specialty and patient factors on 30-day postoperative outcomes and complications for children undergoing autologous costochondral grafting for microtia reconstruction. METHODS The American College of Surgeons National Surgical Quality Improvement Program Pediatric (NSQIP-P) database was searched from 2012 through 2017 for patients who underwent autologous rib grafting (CPT 21230). The group was further filtered for coexisting ICD 9 or 10 code for microtia (744.23, Q17.2) as an indication for surgery. Outcomes analyzed included patient demographics, medical comorbidities, admission type (inpatient vs. outpatient), operative time, surgeon specialty, length of hospital stay (LOS), complications, and readmission. RESULTS A total of 375 pediatric patients were identified of which 157 were female and 218 were male. Mean age at time of surgery was 9.6 years. Postoperative complications and readmission occurred in 5.6% and 3.5% of patients, respectively. Surgical site infection was the most common complication. Average operative time was 246.9 min. When comparing Otolaryngology to Plastic Surgery with multivariate analysis, there was no difference in admission type (OR 1.00, p = 0.993), complication rate (OR 0.91, p = 0.744), readmission (OR 0.68, p = 0.576), operative time (p = 0.471) or total LOS (p = 0.266). CONCLUSION The present study demonstrated postoperative complications and readmission rates following microtia repair as reported by the NSQIP-P database. Overall complication and readmission rates were low. No significant risk factors were identified on multivariate analysis. There were no differences between surgical specialty for complication rate, operative time, hospital stay or readmission when accounting for demographic data and comorbidities.

Abstract
Introduction of novel salvage therapies and expansion of the donor pool within the past decade have allowed more patients with relapsed/refractory (r/r) B cell acute lymphoblastic leukemia (B-ALL) to receive allogeneic hematopoietic cell transplantation (alloHCT). The impact of each salvage therapy on transplant outcomes have not been compared. Our primary objective was to determine post-HCT relapse-free survival (RFS) in adult patients with r/r Philadelphia-chromosome negative (Phneg) B-ALL. We retrospectively studied alloHCT outcomes in 108 adult patients with r/r Phneg B-ALL transplanted in morphological remission achieved by salvage therapy. Salvage therapies were chemotherapy-based combination (n = 45, 42%), blinatumomab (n=43, 40%), inotuzumab (n = 14, 13%), or CAR T cells (n = 6, 6%). The 2-year RFS and overall survival (OS) were 44% and 50%, respectively. In multivariable analysis, conditioning with reduced-intensity or non-myeloablative regimens (hazard ratio [HR] = 2.23, 95% confidence interval [CI], 1.31-3.80; P = .003), having received ≥3 lines of therapies prior to transplant (HR = 2.66, 95% CI, 1.56-4.54; P < .001), and inotuzumab (HR = 2.42, 95% CI, 1.14-5.12; Wald P value = .021) were independently associated with lower RFS. Blinatumomab (HR = 1.10, 95% CI, 0.62-1.96) had comparable RFS to chemotherapy. Incidence of hepatic sinusoidal syndrome was highest with inotuzumab (P < .001); however, 30-day mortality and intensive care unit admissions were not different per salvage therapy. The alloHCT in r/r Phneg B-ALL after remission induction with blinatumomab or chemotherapy led to encouraging outcomes if morphologic CR was achieved. In contrast, pretransplantation inotuzumab therapy was associated with inferior RFS. Larger studies are warranted to confirm our observations. Early transplantation after relapse and the utilization of myeloablative conditioning, when feasible, were key factors associated with improved outcomes after alloHCT in these patients.

Abstract
FMS-like tyrosine kinase 3 (FLT3) mutations are prevalent in acute myeloid leukemia (AML), and their presence confers adverse risk. FLT3-mutated (FLT3m) AML is a challenging leukemia to manage, particularly in older and unfit patients as well as patients with relapsed/refractory (r/r) disease. We retrospectively analyzed the outcomes of 50 FLT3m AML patients (17 treatment-naïve, 33 r/r) treated with venetoclax (VEN) and hypomethylating agents (HMA). The overall CR/CRi rate with VEN-HMA was 60% (94% in treatment-naïve AML and 42% in r/r AML). Early (60-days) treatment related mortality was 2%. The r/r AML setting was an independent predictor of lower complete response (OR: 0.08; 95%CI: 0.00-0.60, P = .03). Cytogenetics-molecular risk, concurrent mutations, the type of FLT3 mutation (ITD vs TKD), the ITD allelic ratio, the type of HMA, age, prior exposure to HMA and receipt of prior allogeneic transplant did not independently impact response or leukemia-free survival (LFS). Concurrent IDH mutations were associated with lower CR/CRi (P = .01), while ASXL1 or TET2 mutations showed a non-significant association toward higher CR/CRi (P = .07, for both). However, none of the concurrent mutations were an independent predictor for response when adjusted to AML setting. In conclusion, VEN-HMA is associated with encouraging efficacy in FLT3m AML among both newly diagnosed unfit and r/r patients.

Abstract
The negative impact of iron overload (IO) on outcomes of allogeneic hematopoietic cell transplantation (HCT) is well recognized, but its impact on umbilical cord blood (UCB) transplant outcome is unknown. We retrospectively analyzed outcomes of 150 patients who received UCB-HCT at our institution, stratified by pre-HCT serum ferritin (SF) level of 2000 ng/mL. Two-year overall survival rate among patients with SF >2000 and ≤2000 ng/mL was 26.1% (95% CI, 10.6% to 44.7%) and 52.1% (95% CI, 40.1% to 62.8%), respectively; hazard ratio (HR) = 2.26 (95% CI, 1.28 to 4.00, P = .005). Two-year nonrelapse mortality rate was higher among patients with SF >2000 ng/mL (56.5%; 95% CI, 33.3% to 74.4%) compared to SF ≤2000 ng/mL (30.1%; 95% CI, 20.0% to 40.9%); HR = 2.18 (95% CI, 1.10 to 4.31, P = .025). Neutrophil engraftment at 42 days was 78.3% (95% CI, 53.5% to 90.8%) in patients with SF >2000 ng/mL versus 91.8% (95% CI, 82.1% to 96.4%) in patients with SF ≤2000 ng/mL; HR = 0.58 (95% CI, 0.35 to 0.96, P = .034). A significant difference in platelet engraftment at 3 months was also observed: 52.2% (95% CI, 29.4% to 70.8%) for SF >2000 ng/mL versus 80.8% (95% CI, 69.5% to 88.3%) for SF ≤2000 ng/mL; HR = 0.48 (95% CI, 0.23 to 0.98, P = .044). In conclusion, IO defined by SF of 2000 ng/mL is a strong adverse prognostic factor for UCB-HCT and should be considered when UCB is chosen as the graft source for patients without a fully matched donor.

Abstract
7559 Background: Chronic myelomonocytic leukemia (CMML) has features of both a myeloproliferative neoplasm and a myelodysplastic syndrome. The median overall survival (OS) in most series is 20-40 months. CMML is a relatively rare entity, and there is limited understanding of prognostic molecular markers. CMML associated with bone marrow fibrosis grade 1, appear to have shorter progression free survival. In this study we investigated the correlation of mutations with bone marrow reticulin fibrosis in patients with CMML. Methods: We investigated a cohort of 41 consecutive patients diagnosed with CMML 0, 1, 2, and CMML-AML from 2014 to 2019 at our institute. The median age of 41 patients was 68 years (range, 34-82). 27% were females and 73% were males. This cohort consists of 8 (20%) patients with CMML0, 19 (46%) with CMML1, 8 (20%) with CMML2 and 6 (15%) with CMML-AML. Genomic DNA was extracted from the bone marrow aspirates and targeted mutation NGS libraries were prepared from 200 ng of genomic DNA using the SureSelect target enrichment system (Agilent Technologies Inc.). The gene panel consists of 73 genes focused on myeloid neoplasms. The data were curated on the basis of our molecular pathology and national databases. Additionally, clinical data and bone marrow (BM) reticulin fibrosis grades (n = 27 available) were retrieved from the patient’s medical record. Results: The mutational profile frequency in our cohort showed that the most common mutations were TET2 (31%), ASXL1 (31%), and SRSF2 (23%), with frequencies very similar to those reported in the literature. Of the 27 cases with an available reticulin stain, only low grade fibrosis (MF-0, n = 18. MF-1, n = 9) were identified in our cohort. The frequencies of mutations in ASXL1, U2AF1, TP53, JAK2 and RUNX1, positively correlated with low grade fibrosis (MF-1). Additionally, patients with higher frequencies of SRSF2, TET2, and SETBP1 mutations showed no fibrosis (MF-0). Conclusions: This study is the first to correlate the degree of fibrosis with the frequency of mutations in CMML. We found similar mutations spectrum reported in the literature in patients with CMML. The mutational profile associated with CMML cases appears to affect the degree of the bone marrow fibrosis at the time of diagnosis.

Abstract
Acute lymphoblastic leukemia (ALL) is associated with poor survival in older adults, and allogeneic hematopoietic cell transplant (HCT) with reduced-intensity conditioning (RIC) has been an increasingly used strategy in this population. At City of Hope we conducted a retrospective analysis of 72 patients who underwent allogeneic HCT with fludarabine and melphalan (FluMel) as the conditioning regimen between 2005 and 2018, from either a matched sibling or fully matched unrelated donor while in complete remission. Tacrolimus and sirolimus (T/S) were used as graft-versus-host disease (GVHD) prophylaxis. Overall survival and progression-free survival at 4 years post-HCT were 58% and 44%, respectively. The cumulative incidences of relapse/progression and nonrelapse mortality at 4 years were 34% and 22%, respectively. Patients with Philadelphia chromosome-positive (Ph+) ALL had a significantly lower cumulative incidence of relapse/progression (20% versus 48% for patients with Ph-negative status, P = .007). In conclusion, RIC HCT with FluMel conditioning and T/S GVHD prophylaxis was associated with favorable outcomes in patients with Ph+ ALL and should be considered as a viable consolidative therapy for adult patients with ALL.

Abstract
BACKGROUND While tacrolimus and sirolimus (T/S)-based graft-versus-host disease (GvHD) prophylaxis has been effective in preventing acute GvHD post hematopoietic cell transplantation (HCT), its efficacy and long-term outcome in matched (MUD) and mismatched unrelated donor (mMUD) setting is not well defined. METHODS Herein, we evaluated a consecutive case-series of 482 patients who underwent unrelated donor HCT (2005-2013) with T/S-based GvHD prophylaxis. RESULTS With a median follow-up of 6.2 years (range = 2.4-11.3), the 5-year overall survival (OS) and relapse/progression-free survival were 47.5% (95% confidence interval [CI]: 43.0-52.0) and 43.6% (95% CI: 39.1-48.1), respectively; and the 5-year cumulative incidence of nonrelapse mortality (NRM) and relapse were 24.9%, and 31.5%, respectively. In this cohort, mMUD was associated with worse OS (39.0% versus 50.7% at 5 y; P = 0.034), primarily due to greater risk of NRM (33.5% versus 21.7%; P = 0.038). While rates of relapse, acute (II-IV or III-IV) or chronic GvHD (limited or extensive) were not different, death caused by chronic GvHD (20.8% versus 12.8%; P = 0.022) and infection (33.0% versus 18.1%; P < 0.01) were significantly greater in mMUD. In multivariable analysis, high-risk disease (hazard ratio [HR] = 2.21, 95% CI: 1.16-4.23; P < 0.01) and mMUD (HR = 1.55, 95% CI: 1.15-2.08; P = 0.004) were independent predictive factors for OS. CONCLUSIONS T/S-based GvHD prophylaxis is an effective and acceptable GvHD prophylactic regimen. However, survival after mMUD remained poor, possibly related to the severity of chronic GvHD.

Abstract
Historically, outcomes of adult patients with relapsed acute lymphoblastic leukemia (ALL) who fail to enter remission with conventional chemotherapy are very poor. Blinatumomab, a bispecific CD3/CD19 antibody, has shown remarkable activity in relapsed/refractory (r/r) ALL. Although allogeneic hematopoietic cell transplant (HCT) is the recommended consolidation therapy for patients with r/r ALL who respond to salvage therapy, HCT and toxicity outcomes for those who received blinatumomab salvage and HCT remain largely unknown. We treated 89 patients with r/r ALL with blinatumomab, of whom 43 patients (48%) achieved remission. Here we describe our single-center experience in the subset of patients who responded to blinatumomab salvage therapy for eradication of either gross (n = 24) or minimal residual disease (n = 11) before HCT. Overall survival at 1 and 2 years after allogeneic HCT was 77% and 52%, respectively. Leukemia-free survival at 1 and 2 years were 65% and 40%, respectively. Additionally, with blinatumomab administration pre-HCT, no unusual toxicities such as delayed neutrophil/platelet engraftment or graft failure were observed. Acute grades II to IV graft-versus-host disease (GVHD) at day +100 post-HCT was at 43% and 2-year chronic GVHD was 36%, both comparable with historic control subjects. Finally, results of our subset analysis based on pre-HCT minimal residual disease (MRD) status indicated no significant difference in survival outcomes among patients undergoing transplant in MRD-negative status and the entire cohort. In conclusion, based on results of this study, blinatumomab may be considered as a safe and effective agent for r/r ALL patients before HCT.

Abstract
It remains unknown whether the administration of tyrosine kinase inhibitors (TKIs) targeting BCR-ABL1 after allogeneic hematopoietic cell transplantation (HCT) is associated with improved outcomes for patients with chronic myelogenous leukemia (CML). In this registry study, we analyzed clinical outcomes of 390 adult patients with CML who underwent transplantation between 2007 and 2014 and received maintenance TKI following HCT (n = 89) compared with no TKI maintenance (n = 301), as reported to the Center for International Blood and Marrow Transplant Research. All patients received TKI therapy before HCT. The majority of patients had a disease status of first chronic phase at HCT (n = 240; 62%). The study was conducted as a landmark analysis, excluding patients who died, relapsed, had chronic graft-versus-host disease, or were censored before day +100 following HCT. Of the 89 patients who received TKI maintenance, 77 (87%) received a single TKI and the other 12 (13%) received multiple sequential TKIs. The most common TKIs used for maintenance were dasatinib (n = 50), imatinib (n = 27), and nilotinib (n = 27). As measured from day +100, the adjusted estimates for 5-year relapse (maintenance, 35% versus no maintenance, 26%; P = .11), leukemia-free survival (maintenance, 42% versus no maintenance, 44%; P = .65), or overall survival (maintenance, 61% versus no maintenance, 57%; P = .61) did not differ significantly between patients receiving TKI maintenance or no maintenance. These results remained unchanged in multivariate analysis and were not modified by disease status before transplantation. In conclusion, our data from this day +100 landmark analysis do not demonstrate a significant impact of maintenance TKI therapy on clinical outcomes. The optimal approach to TKI administration in the post-transplantation setting in patients with CML remains undetermined.

Abstract
A mismatch at HLA-DPB1 locus is associated with higher acute GVHD and lower relapse rate after myeloablative (MAC) allogeneic hematopoietic cell transplantation (alloHCT). Also, in MAC setting, mismatch permissiveness and expression level impact alloHCT outcomes. However, in reduced intensity (RIC), DP mismatch effect on transplant outcomes is unknown. We retrospectively evaluated DP mismatch influence (number, permissiveness, and expression) on HCT outcomes in 310 patients with high-resolution typing (HLA-A, -B, -C, -DRB1, -DQB1 and -DPB1), who underwent RIC-HCT. By multivariable analysis, 11/12 had better overall survival (OS) and relapse vs. 12/12 (HR=1.61 and 2.02; p=0.04 and 0.01, respectively) and better OS vs. 10/12 (HR=1.68; p=0.02). Within the 11/12, non-permissive mismatch (NoPR) was associated with higher risk of grade II-IV acute GVHD (HR=1.97; p=0.005) and non-relapse mortality (HR=2.13; p=0.02) vs. permissive (PR). Grouping 11/12 based on the DP expression conferred higher mortality (HR=3.78; p= 0.003) when low expressers received a graft from high expressers (AG) vs. low expressers (AA). Better OS was achieved in PR 11/12, when expression was low in patient and donor (AA) vs. all other combinations. Therefore, in RIC HCT, a single DP mismatch has a protective role, especially in permissive setting, when donor and recipient are low expressers.

Abstract
Paroxysmal nocturnal hemoglobinuria (PNH) is frequently seen in the context of other aplastic anemia and myelodysplastic syndromes and is associated with hemolysis and increased thromboembolic events. Allogeneic hematopoietic stem cell transplantation (alloHCT) is the sole curative treatment but is associated with significant morbidity. The terminal complement inhibitor eculizumab reduces hemolysis and thromboembolic events and is the sole Food and Drug Administration-approved therapy for PNH. Prophylactic administration of this agent in the early post-transplantation setting to prevent hemolysis and thrombosis has not been described in the literature. We describe our institutional experience of 8 patients with PNH who underwent alloHCT and who received at least 1 dose of eculizumab within 30 days of alloHCT for prevention of thrombosis and hemolysis. One patient with underlying aplastic anemia who received bone marrow stem cells failed to engraft. Another patient experienced steroid-refractory grade IV acute graft-versus-host disease and died of a fungal infection. The other patients engrafted well; no hemolysis, thrombotic events, or infections associated with encapsulated bacteria occurred in any of the 8 patients.

Abstract
OBJECTIVE We tested the ability of a type 1 diabetes (T1D) genetic risk score (GRS) to predict progression of islet autoimmunity and T1D in at-risk individuals. RESEARCH DESIGN AND METHODS We studied the 1,244 TrialNet Pathway to Prevention study participants (T1D patients' relatives without diabetes and with one or more positive autoantibodies) who were genotyped with Illumina ImmunoChip (median [range] age at initial autoantibody determination 11.1 years [1.2-51.8], 48% male, 80.5% non-Hispanic white, median follow-up 5.4 years). Of 291 participants with a single positive autoantibody at screening, 157 converted to multiple autoantibody positivity and 55 developed diabetes. Of 953 participants with multiple positive autoantibodies at screening, 419 developed diabetes. We calculated the T1D GRS from 30 T1D-associated single nucleotide polymorphisms. We used multivariable Cox regression models, time-dependent receiver operating characteristic curves, and area under the curve (AUC) measures to evaluate prognostic utility of T1D GRS, age, sex, Diabetes Prevention Trial-Type 1 (DPT-1) Risk Score, positive autoantibody number or type, HLA DR3/DR4-DQ8 status, and race/ethnicity. We used recursive partitioning analyses to identify cut points in continuous variables. RESULTS Higher T1D GRS significantly increased the rate of progression to T1D adjusting for DPT-1 Risk Score, age, number of positive autoantibodies, sex, and ethnicity (hazard ratio [HR] 1.29 for a 0.05 increase, 95% CI 1.06-1.6; P = 0.011). Progression to T1D was best predicted by a combined model with GRS, number of positive autoantibodies, DPT-1 Risk Score, and age (7-year time-integrated AUC = 0.79, 5-year AUC = 0.73). Higher GRS was significantly associated with increased progression rate from single to multiple positive autoantibodies after adjusting for age, autoantibody type, ethnicity, and sex (HR 2.27 for GRS >0.295, 95% CI 1.47-3.51; P = 0.0002). CONCLUSIONS The T1D GRS independently predicts progression to T1D and improves prediction along T1D stages in autoantibody-positive relatives.

Abstract
Colchicine overdose is uncommon but potentially life threatening. Due to its serious adverse systemic effects, overdose must be recognized and treated. We report a case of an 18-year-old female who ingested 18 mg (~0.4 mg/kg) of colchicine in a suicide attempt. The patient's clinical manifestations included abdominal cramps, vomiting, pancytopenia, hypocholesterolemia, and rhabdomyolysis. Two unique manifestations of toxicity in this patient were profound and persistent, severe hypertriglyceridemia and electrolyte imbalance, mainly hypophosphatemia, with no other evident cause except the colchicine intoxication. Following intensive supportive treatment, including ventilator support, N-acetylcysteine, granulocyte colony stimulating factor, electrolyte repletion, and zinc supplementation, the patient made a complete recovery. Colchicine intoxication is a severe, life-threatening situation that should be followed closely in intensive care units. Severe changes in body functions can rapidly develop, as previously described in the literature. To our knowledge, this extremely elevated triglyceride level has never been reported without the administration of propofol, and requires further evaluation.

Abstract
Therapy-related acute lymphoblastic leukemia remains poorly defined due to a lack of large data sets recognizing the defining characteristics of this entity. We reviewed all consecutive cases of adult acute lymphoblastic leukemia treated at our institution between 2000 and 2017 and identified therapy-related cases - defined as acute lymphoblastic leukemia preceded by prior exposure to cytotoxic chemotherapy and/or radiation. Of 1022 patients with acute lymphoblastic leukemia, 93 (9.1%) were classified as therapy-related. The median latency for therapy-related acute lymphoblastic leukemia onset was 6.8 years from original diagnosis, and this was shorter for patients carrying the MLL gene rearrangement compared to those with other cytogenetics. When compared to de novo acute lymphoblastic leukemia, therapy-related patients were older (P<0.01), more often female (P<0.01), and had more MLL gene rearrangement (P<0.0001) and chromosomes 5/7 aberrations (P=0.02). Although therapy-related acute lymphoblastic leukemia was associated with inferior 2-year overall survival compared to de novo cases (46.0% vs 68.1%, P=0.001), prior exposure to cytotoxic therapy (therapy-related) did not independently impact survival in multivariate analysis (HR=1.32; 95% CI: 0.97-1.80, P=0.08). There was no survival difference (2-year = 53.4% vs 58.9%, P=0.68) between the two groups in patients who received allogenic hematopoietic cell transplantation. In conclusion, therapy-related acute lymphoblastic leukemia represents a significant proportion of adult acute lymphoblastic leukemia diagnoses, and a subset of cases carry clinical and cytogenetic abnormalities similar to therapy-related myeloid neoplasms. Although survival of therapy-related acute lymphoblastic leukemia was inferior to de novo cases, allogeneic hematopoietic cell transplantation outcomes were comparable for the two entities.

Abstract
Allogeneic hematopoietic stem cell transplantation (alloHCT) is offered increasingly to elderly patients with hematologic malignancies. However, outcome data in those who are 70 years or older are limited, and no standard conditioning regimen has been established for this population. In this retrospective study we evaluated the outcome of 53 consecutive patients aged 70 years and older who underwent alloHCT with melphalan-based reduced-intensity conditioning (RIC) at City of Hope. Engraftment was prompt, with median time to neutrophil engraftment of 15 days. More than 95% of patients achieved complete donor chimerism within 6 weeks from HCT, consistent with the "semiablative" nature of this regimen. With a median follow-up of 31.1 months, the 2-year overall survival (OS), progression-free survival (PFS), and nonrelapse mortality (NRM) were 68.9%, 63.8%, and 17.0%, respectively. Cumulative incidence of relapse at 1 and 2 years was 17.0% and 19.3%, respectively. One hundred-day cumulative incidence of grades II to IV acute graft-versus-host disease was 37.7% (grades III to IV, 18.9%), and 2-year cumulative incidence of chronic graft-versus-host disease was 61.9% (extensive, 45.9%). The only significant predictor for poor OS was high/very high disease risk index. Transplant-related complications and morbidities observed here did not differ from the commonly expected in younger patients treated with RIC. In conclusion, alloHCT with a melphalan-based conditioning regimen is associated with acceptable toxicities and NRM, lower incidence of relapse, and favorable OS and PFS in patients aged 70 years or older.

Abstract
Myelofibrosis (MF) is a chronic yet progressive myeloid neoplasm in which only a minority of patients undergo curative therapy, hematopoietic stem cell transplantation. Ruxolitinib, a JAK1/2 inhibitor, is the lone therapy approved for MF, offering a clear symptom and spleen benefit at the expense of treatment-related cytopenias. Pacritinib (PAC), a multi-kinase inhibitor with specificity for JAK2, FLT3, and IRAK1 but sparing JAK1, has demonstrated clinical activity in MF with minimal myelosuppression. Due to an FDA-mandated full clinical hold, the randomized phase 3 PERSIST trials were abruptly stopped and PAC was immediately discontinued for all patients. Thirty-three patients benefitting from PAC on clinical trial prior to the hold were allowed to resume therapy on an individual, compassionate-use basis. This study reports the detailed outcomes of 19 of these PAC retreatment patients with a median follow-up of 8 months. Despite a median platelet count of 49 × 109/L at restart of PAC, no significant change in hematologic profile was observed. Grade 3/4 adverse events of epistaxis (n = 1), asymptomatic QT prolongation (n = 1), and bradycardia (n = 1) occurred in three patients within the first 3 months of retreatment. One death due to catheter-associated sepsis occurred. The median time to discontinuation of PAC therapy on compassionate use for all 33 patients was 12.2 (95% CI 8.3-NR) months. PAC retreatment was associated with modest improvement in splenomegaly without progressive myelosuppression and supports the continued development of this agent for the treatment of MF second line to ruxolitinib or in the setting of treatment-limiting thrombocytopenia.

Abstract
Therapy-related myelodysplastic syndrome is a long-term complication of cancer treatment in patients receiving cytotoxic therapy, characterized by high-risk genetics and poor outcomes. Allogeneic hematopoietic cell transplantation is the only potential cure for this disease, but the prognostic impact of pre-transplant genetics and clinical features has not yet been fully characterized. We report here the genetic and clinical characteristics and outcomes of a relatively large cohort of patients with therapy-related myelodysplastic syndrome (n=67) who underwent allogeneic transplantation, comparing these patients to similarly treated patients with de novo disease (n=199). The 5-year overall survival was not different between patients with therapy-related and de novo disease (49.9% versus 53.9%; P=0.61) despite a higher proportion of individuals with an Intermediate-2/High International Prognostic Scoring System classification (59.7% versus 43.7%; P=0.003) and high-risk karyotypes (61.2% versus 30.7%; P<0.01) among the patients with therapy-related disease. In mutational analysis, TP53 alteration was the most common abnormality in patients with therapy-related disease (n=18: 30%). Interestingly, the presence of mutations in TP53 or in any other of the high-risk genes (EZH2, ETV6, RUNX1, ASXL1: n=29: 48%) did not significantly affect either overall survival or relapse-free survival. Allogeneic stem-cell transplantation is, therefore, a curative treatment for patients with therapy-related myelodysplastic syndrome, conferring a similar long-term survival to that of patients with de novo disease despite higher-risk features. While TP53 alteration was the most common mutation in therapy-related myelodysplastic syndrome, the finding was not detrimental in our case-series.

Abstract
Current conditioning regimens provide insufficient disease control in relapsed/refractory acute leukemia patients undergoing hematopoietic stem cell transplantation (HSCT) with active disease. Intensification of chemotherapy and/or total body irradiation (TBI) is not feasible because of excessive toxicity. Total marrow and lymphoid irradiation (TMLI) allows for precise delivery and increased intensity treatment via sculpting radiation to sites with high disease burden or high risk for disease involvement, while sparing normal tissue. We conducted a phase I trial in 51 patients (age range, 16 to 57 years) with relapsed/refractory acute leukemia undergoing HSCT (matched related, matched unrelated, or 1-allele mismatched unrelated) with active disease, combining escalating doses of TMLI (range, 1200 to 2000 cGy) with cyclophosphamide (CY) and etoposide (VP16). The maximum tolerated dose was declared at 2000 cGy, as TMLI simulation studies indicated that >2000 cGy might deliver doses toxic for normal organs at or exceeding those delivered by standard TBI. The post-transplantation nonrelapse mortality (NRM) rate was only 3.9% (95% confidence interval [CI], .7 to 12.0) at day +100 and 8.1% (95% CI, 2.5 to 18.0) at 1 year. The cumulative incidence of grades II to IV acute graft-versus-host disease (GVHD) was 43.1% (95% CI, 29.2 to 56.3) and for grade III and IV, it was 13.7% (95% CI, 6.9 to 27.3). The day +30 complete remission rate for all patients was 88% and was 100% for those treated at 2000 cGy. The overall 1-year survival was 55.5% (95% CI, 40.7 to 68.1). The TMLI/CY/VP16 conditioning regimen is well tolerated at TMLI doses up to 2000 cGy with a low 100-day and 1-year NRM rate and no increased risk of GVHD with higher doses of radiation.

Abstract
This paper provides a determination of the equivalent level of protection of the international standards relative to similar criteria used by the U.S. Mine Safety and Health Administration (MSHA) to approve two-fault intrinsically safe (IS) stand-alone equipment. U.S. mining law requires such a determination for MSHA to use alternatives to existing standards. The primary issue is to demonstrate that the international standards for equipment evaluation will provide at least the same level of protection for miners as the document currently used by MSHA.

The ability of ISBs to kill the biting midge Culicoides sonorensis Wirth and Jones (Diptera: Ceratopogonidae), a vector of bluetongue virus, epizootic hemorrhagic disease and vesicular stomatitis viruses, was tested. The commercial insecticide formulations (percentage active ingredient) tested included bifenthrin, cyfluthrin, deltamethrin, permethrin, dinotefuran, imidacloprid, thiamethoxam and spinosad. Mortality rates were determined for various concentrations of commercial formulations (0.01, 0.05, 0.1, 1, 2 and 3%) and observed at 1, 4, 10 and 24 h post-exposure to the ISB. In the first set of assays, laboratory-reared midges were fed sugar ad libitum and then exposed to insecticide-treated sugar solutions to measure mortality. The second assay assessed competitive feeding: midges were provided with a control sugar solution (10% sucrose) in one vial, and a sugar and insecticide solution in another. Pyrethroid treatments resulted in the greatest mortality in the first hour at the lowest concentrations and spinosad consumption resulted in the least mortality. Biting midges were not deterred from feeding on the 1% ISB solutions despite the presence of an insecticide-free alternative source of sugar.

Abstract
The biting midge Culicoides sonorensis Wirth and Jones (Diptera: Ceratopogonidae) transmits pathogens to both livestock and wildlife. Biting midge surveillance relies heavily on light traps for collection; however, little is known about the light spectra preferences of C. sonorensis midges. A light assay arena was constructed and light-emitting diodes (LEDs) of various light spectra were used as light sources to evaluate midge photoattraction. A comparison of responses to light spectra indicated the highest proportions of C. sonorensis were attracted to ultraviolet (UV) light and that midges differentiated 10-nm differences in wavelength. Stronger intensities of UV light resulted in greater attraction. Midges exhibited both sugar-seeking and escape behaviours under different conditions of sugar supplementation before and during the experiment. These behaviours occurred with lights of 355 nm and 365 nm in wavelength. Based on the results of this study, the attraction of C. sonorensis to light traps can be improved through the use of bright LEDs at 355 nm or 365 nm.

Abstract
The classical Philadelphia chromosome-negative myeloproliferative neoplasms (MPN), which include essential thrombocythemia, polycythemia vera, and myelofibrosis (MF), are in a new era of molecular diagnosis, ushered in by the identification of the JAK2(V617F) and cMPL mutations in 2005 and 2006, respectively, and the CALR mutations in 2013. Coupled with increased knowledge of disease pathogenesis and refined diagnostic criteria and prognostic scoring systems, a more nuanced appreciation has emerged of the burden of MPN in the United States, including the prevalence, symptom burden, and impact on quality of life. Biological advances in MPN have translated into the rapid development of novel therapeutics, culminating in the approval of the first treatment for MF, the JAK1/JAK2 inhibitor ruxolitinib. However, certain practical aspects of care, such as those regarding diagnosis, prevention of vascular events, choice of cytoreductive agent, and planning for therapies, present challenges for hematologists/oncologists, and are discussed in this article.
