Abstract
OBJECTIVE The goal was to characterize short-term kidney status and describe variation in early care utilization in a multicenter cohort of patients with childhood-onset systemic lupus erythematosus (cSLE) and nephritis. METHODS We analyzed previously collected prospective data from North American patients with cSLE with kidney biopsy-proven nephritis enrolled in the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry from March 2017 through December 2019. We determined the proportion of patients with abnormal kidney status at the most recent registry visit and applied generalized linear mixed models to identify associated factors. We also calculated frequency of medication use, both during induction and ever recorded. RESULTS We identified 222 patients with kidney biopsy-proven nephritis, with 64% class III/IV nephritis on initial biopsy. At the most recent registry visit at median (interquartile range) of 17 (8-29) months from initial kidney biopsy, 58 of 106 patients (55%) with available data had abnormal kidney status. This finding was associated with male sex (odds ratio [OR] 3.88, 95% confidence interval [95% CI] 1.21-12.46) and age at cSLE diagnosis (OR 1.23, 95% CI 1.01-1.49). Patients with class IV nephritis were more likely than class III to receive cyclophosphamide and rituximab during induction. There was substantial variation in mycophenolate, cyclophosphamide, and rituximab ever use patterns across rheumatology centers. CONCLUSION In this cohort with predominately class III/IV nephritis, male sex and older age at cSLE diagnosis were associated with abnormal short-term kidney status. We also observed substantial variation in contemporary medication use for pediatric lupus nephritis between pediatric rheumatology centers. Additional studies are needed to better understand the impact of this variation on long-term kidney outcomes.

Abstract
BACKGROUND Children with juvenile idiopathic arthritis (JIA) who achieve a drug free remission often experience a flare of their disease requiring either intraarticular steroids (IAS) or systemic treatment with disease modifying anti-rheumatic drugs (DMARDs). IAS offer an opportunity to recapture disease control and avoid exposure to side effects from systemic immunosuppression. We examined a cohort of patients treated with IAS after drug free remission and report the probability of restarting systemic treatment within 12 months. METHODS We analyzed a cohort of patients from the Childhood Arthritis and Rheumatology Research Alliance (CARRA) Registry who received IAS for a flare after a period of drug free remission. Historical factors and clinical characteristics and of the patients including data obtained at the time of treatment were analyzed. RESULTS We identified 46 patients who met the inclusion criteria. Of those with follow up data available 49% had restarted systemic treatment 6 months after IAS injection and 70% had restarted systemic treatment at 12 months. The proportion of patients with prior use of a biologic DMARD was the only factor that differed between patients who restarted systemic treatment those who did not, both at 6 months (79% vs 35%, p < 0.01) and 12 months (81% vs 33%, p < 0.05). CONCLUSION While IAS are an option for all patients who flare after drug free remission, it may not prevent the need to restart systemic treatment. Prior use of a biologic DMARD may predict lack of success for IAS. Those who previously received methotrexate only, on the other hand, are excellent candidates for IAS.

Abstract
Neuroblastoma (NB) is the second leading extracranial solid tumor of early childhood with about two-thirds of cases presenting before the age of 5, and accounts for roughly 15 percent of all pediatric cancer fatalities in the United States. Treatments against NB are lacking, resulting in a low survival rate in high-risk patients. A repurposing approach using already approved or clinical stage compounds can be used for diseases for which the patient population is small, and the commercial market limited. We have used Bayesian machine learning, in vitro cell assays, and combination analysis to identify molecules with potential use for NB. We demonstrated that pyronaridine (SH-SY5Y IC50 1.70 µM, SK-N-AS IC50 3.45 µM), BAY 11-7082 (SH-SY5Y IC50 0.85 µM, SK-N-AS IC50 1.23 µM), niclosamide (SH-SY5Y IC50 0.87 µM, SK-N-AS IC50 2.33 µM) and fingolimod (SH-SY5Y IC50 4.71 µM, SK-N-AS IC50 6.11 µM) showed cytotoxicity against NB. As several of the molecules are approved drugs in the US or elsewhere, they may be repurposed more readily for NB treatment. Pyronaridine was also tested in combinations in SH-SY5Y cells and demonstrated an antagonistic effect with either etoposide or crizotinib. Whereas when crizotinib and etoposide were combined with each other they had a synergistic effect in these cells. We have also described several analogs of pyronaridine to explore the structure-activity relationship against cell lines. We describe multiple molecules demonstrating cytotoxicity against NB and the further evaluation of these molecules and combinations using other NB cells lines and in vivo models will be important in the future to assess translational potential.

Abstract
BACKGROUND Stratifying risk of postoperative pulmonary complications after major abdominal surgery allows clinicians to modify risk through targeted interventions and enhanced monitoring. In this study, we aimed to identify and validate prognostic models against a new consensus definition of postoperative pulmonary complications. METHODS We did a systematic review and international external validation cohort study. The systematic review was done in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. We searched MEDLINE and Embase on March 1, 2020, for articles published in English that reported on risk prediction models for postoperative pulmonary complications following abdominal surgery. External validation of existing models was done within a prospective international cohort study of adult patients (≥18 years) undergoing major abdominal surgery. Data were collected between Jan 1, 2019, and April 30, 2019, in the UK, Ireland, and Australia. Discriminative ability and prognostic accuracy summary statistics were compared between models for the 30-day postoperative pulmonary complication rate as defined by the Standardised Endpoints in Perioperative Medicine Core Outcome Measures in Perioperative and Anaesthetic Care (StEP-COMPAC). Model performance was compared using the area under the receiver operating characteristic curve (AUROCC). FINDINGS In total, we identified 2903 records from our literature search; of which, 2514 (86·6%) unique records were screened, 121 (4·8%) of 2514 full texts were assessed for eligibility, and 29 unique prognostic models were identified. Nine (31·0%) of 29 models had score development reported only, 19 (65·5%) had undergone internal validation, and only four (13·8%) had been externally validated. Data to validate six eligible models were collected in the international external validation cohort study. Data from 11 591 patients were available, with an overall postoperative pulmonary complication rate of 7·8% (n=903). None of the six models showed good discrimination (defined as AUROCC ≥0·70) for identifying postoperative pulmonary complications, with the Assess Respiratory Risk in Surgical Patients in Catalonia score showing the best discrimination (AUROCC 0·700 [95% CI 0·683-0·717]). INTERPRETATION In the pre-COVID-19 pandemic data, variability in the risk of pulmonary complications (StEP-COMPAC definition) following major abdominal surgery was poorly described by existing prognostication tools. To improve surgical safety during the COVID-19 pandemic recovery and beyond, novel risk stratification tools are required. FUNDING British Journal of Surgery Society.

Abstract
Abstract
Introduction: Chordoma is a rare tumor with a median survival of 7 years in US. At present, standard treatment involves surgery and/or radiation. Complete surgical resection, however, can be challenging as the tumor is located on the skull base or spine. Moreover, there is currently no approved systemic therapy for advanced chordoma. These challenges have resulted in significant morbidity and a dismal cure rate of approximately 30%, highlighting the need for development of new therapeutic strategies for this orphan disease. Emerging evidence suggests a key role for the PI3K/mTOR pathway in chordoma and numerous reports point to an enrichment of chordoma cases in individuals with tuberous sclerosis syndrome, which is driven by dysregulated mTOR activity. Another study of chordoma tumors from 111 patients demonstrated that the mTOR pathway was activated in 46% of the tumors, and sequencing studies have revealed oncogenic alterations to the PI3K/mTOR pathway in approximately 15-20% of chordomas. We surmised that dual inhibition of both the mTOR and the PI3K pathways may represent a desirable profile as it will not only have the potential to address the effects of activation of both these targets, but also prevent feedback reactivation of the pathway resulting from the inhibition of one or the other. Previously, SPR965 was shown as a potent, selective and orally bioavailable PI3K and mTOR C1/C2 inhibitor with an excellent PK/ADME profile.
Methods: SPR965 and comparator compounds were evaluated in vitro in the chordoma cell lines JHC7, U-CH1, and U-CH2 by (Resarufin assay). SPR965 was evaluated in vivo in multiple chordoma PDX models.
Results: SPR965 in vitro showed significant effect on cell proliferation with EC50 of 50-90nM. SPR965 was more active at 1uM than PI3K/mTOR inhibitors VS-5584, Bimiralisib, PF-04691502, WYE-687, Dactolisib, and Voxtalisib in the Kinase Chemogenomic Set. SPR965 in vivo monotherapy in SF8894 PDX at 3mg/kg had similar tumor growth inhibition (TGI) to CDK4/6 inhibitor Palbociclib at 50mg/kg. SPR965 combination with Palbocicilib had similar TGI to PI3K inhibitor Buparlisib at 35mg/kg. In CF459 PDX, SPR965 potently inhibited tumor growth at 10mg/kg. TGI% was statistically significant with SPR965 versus untreated controls in both models.
Conclusion: In SF8894 PDX model SPR965 was more efficacious as it produced similar tumor growth inhibition at 12- and 17-fold lower dose than Buparlisib (PI3K) and Palbociclib (CDK4/6) respectively, both these compounds are in phase 2 clinical trials. In CF459 PDX model SPR965 exhibited dose-dependent tumor growth inhibition, and at 10mg/kg profoundly slowed tumor growth compared to Palbociclib. Studies are underway to elucidate potential mechanisms of SPR965 sensitivity. SPR965 represents a significant opportunity for development of a targeted therapeutic for chordoma patients.

Abstract
Little is known about those who are widowed while raising dependent children. This study aimed to explore the factors which influence adjustment to partner death. Seven fathers and five mothers were interviewed, and constructivist grounded theory was used. Three interrelated themes were identified: Interpersonal influences, Intrapersonal influences, and Contextual influences. Dependent children meant sole responsibility and increased demands, yet ultimately provided widowed parents a purpose. Participants highlighted the need for increased awareness of young widowhood at a systemic and cultural level, to improve communication around death and young widowhood. Implications included social, financial and therapeutic interventions.

Abstract
BACKGROUND Social determinants of health (SDH) greatly influence outcomes during the first year of treatment in rheumatoid arthritis, a disease similar to polyarticular juvenile idiopathic arthritis (pJIA). We investigated the correlation of community poverty level and other SDH with the persistence of moderate to severe disease activity and functional disability over the first year of treatment in pJIA patients enrolled in the Childhood Arthritis and Rheumatology Research Alliance Registry. METHODS In this cohort study, unadjusted and adjusted generalized linear mixed effects models analyzed the effect of community poverty and other SDH on disease activity, using the clinical Juvenile Arthritis Disease Activity Score-10, and disability, using the Child Health Assessment Questionnaire, measured at baseline, 6, and 12 months. RESULTS One thousand six hundred eighty-four patients were identified. High community poverty (≥20% living below the federal poverty level) was associated with increased odds of functional disability (OR 1.82, 95% CI 1.28-2.60) but was not statistically significant after adjustment (aOR 1.23, 95% CI 0.81-1.86) and was not associated with increased disease activity. Non-white race/ethnicity was associated with higher disease activity (aOR 2.48, 95% CI: 1.41-4.36). Lower self-reported household income was associated with higher disease activity and persistent functional disability. Public insurance (aOR 1.56, 95% CI 1.06-2.29) and low family education (aOR 1.89, 95% CI 1.14-3.12) was associated with persistent functional disability. CONCLUSION High community poverty level was associated with persistent functional disability in unadjusted analysis but not with persistent moderate to high disease activity. Race/ethnicity and other SDH were associated with persistent disease activity and functional disability.

In 2021, the ICRP initiated the revision of the general recommendations of the system of radiation protection, and part of it will focus on dose quantities. The recently published ICRP Publication 147 and ICRU Report 95 have described the extent of the proposed modifications and paved the way for the strategy to be adopted. These revisions would seek to simplify, improve the accuracy and extend the field of use of dose quantities. While the Radiological Protection Working Group of the World Nuclear Association recognises the notable improvement in the estimation of the protection quantities and the usefulness of such changes for the medical and research sector, the benefits of the proposed new system seem very limited for the nuclear industry and industries involving naturally occurring radioactive materials. The complexity associated with changing a long-standing and robust system and the risk incurred by the human factor seem unjustified, bearing in mind the likely cost.

Abstract
BACKGROUND AND PURPOSE Posterior fossa type A (PFA) ependymomas have 2 molecular subgroups (PFA-1 and PFA-2) and 9 subtypes. Gene expression profiling suggests that PFA-1 and PFA-2 tumors have distinct developmental origins at different rostrocaudal levels of the brainstem. We, therefore, tested the hypothesis that PFA-1 and PFA-2 ependymomas have different anatomic MR imaging characteristics at presentation. MATERIALS AND METHODS Two neuroradiologists reviewed the preoperative MR imaging examinations of 122 patients with PFA ependymomas and identified several anatomic characteristics, including extension through the fourth ventricular foramina and encasement of major arteries and tumor type (midfloor, roof, or lateral). Deoxyribonucleic acid methylation profiling assigned ependymomas to PFA-1 or PFA-2. Information on PFA subtype from an earlier study was also available for a subset of tumors. Associations between imaging variables and subgroup or subtype were evaluated. RESULTS No anatomic imaging variable was significantly associated with the PFA subgroup, but 5 PFA-2c subtype ependymomas in the cohort had a more circumscribed appearance and showed less tendency to extend through the fourth ventricular foramina or encase blood vessels, compared with other PFA subtypes. CONCLUSIONS PFA-1 and PFA-2 ependymomas did not have different anatomic MR imaging characteristics, and these results do not support the hypothesis that they have distinct anatomic origins. PFA-2c ependymomas appear to have a more anatomically circumscribed MR imaging appearance than the other PFA subtypes; however, this needs to be confirmed in a larger study.

Abstract
Purpose/Objective(s) COVID-19 has dramatically increased telehealth utilization for cancer care delivery. We hypothesized that patient satisfaction scores following virtual visits may improve over time as patients and physicians become more accustomed to a virtual platform. To evaluate this, we compared virtual visit patient satisfaction scores between early and late pandemic visits at a comprehensive cancer center. Materials/Methods Anonymized patient surveys from all virtual visit (VV) and in-person visits (IP) collected between April 2020 through January 2021 were included. Surveys consisted of 12 questions assessing the following aspects of the patient experience: connection quality, patient-physician communication, and overall provider quality. Open-ended questions (2/12) were excluded. Qualitative responses were given on a 1-3 Likert-type scale ranging from no, yes (somewhat), and yes (definitely). Surveys were grouped into early-pandemic (April 2020 - July 2020) and late-pandemic (August 2020 - January 2021). Responses were binned into satisfied (yes, [definitely] responses) and not satisfied (no and yes [somewhat] responses). Patient characteristics and survey responses for early and late pandemic were compared using a chi-square or independent t-test with significance set at P < 0.05. Results In total, 1,688 VV (45% early and 55% late pandemic) and 5,279 IP (39% early and 61% late pandemic) surveys were assessed. VV surveys were from the following specialties: 69% medical oncology, 13% surgical oncology, 12% radiation oncology, and 6% gynecologic oncology. The age distribution of VV patients was ≤49 (16%), 50-64 (28%), and ≥65 (56%) years compared to ≤49 (16%), 50-64 (32%), and ≥65 (52%) for IP patients. Survey response rates were 41% and 42% for VV and IP patients, respectively. Compared to early pandemic VV patients, late pandemic VV patients were more satisfied with regard to quality of explanation (91% vs 80%, P < .001), provider preparedness (89% vs 81%, P < 0.001), patient-provider trust (93% vs 87%, P < 0.001), provider listening (94% vs 86%, P < 0.001), follow-up instructions (85% vs 76%, P < 0.001), connection ease (83% vs 71%, P < 0.001), connection quality (85% vs 72%, P < 0.001), and appointment timing (84% vs 66%, P < 0.001). There was no significant difference between early and late pandemic for overall provider rating (mean [SD], 1-10 scale: 9.52 [1.45] vs. 9.58 [1.29], P = 0.36) or whether the patient would recommend the provider (94.6% vs. 92.3%, P = 0.10). In contrast, no significant differences were observed in patient survey scores between early and late pandemic for IP visits. Conclusion Patients who had virtual visits were significantly more satisfied on multiple aspects of their encounter later in the pandemic compared with earlier while no significant differences were observed for in-person visits. Understanding the underlying reasons will be important for optimizing the virtual patient experience, which is likely to remain a common way of “seeing” patients.

Abstract
Abstract
Introduction/Objective
The autopsy is an undervalued and underutilized resource in medicine. Many people believe autopsies are used solely in forensics while in fact much of what we know about human disease comes from examining the human body at autopsy. The decrease in requests for autopsy over the past several decades possibly results from medical professionals’ lack of exposure to and understanding of autopsy. We conducted a survey to explore non-pathologist physicians’ exposure to and understanding of the autopsy and discover challenges and barriers faced by non-pathologists when requesting an autopsy. Better understanding of non-pathologist physicians’ views and experiences can guide further inquiry or intervention to remove barriers to autopsy requests.
Methods/Case Report
We disseminated a Google Forms survey via Twitter, tweeting weekly between 10/26/20- 2/26/2021 to obtain a convenience sample. Mean differences in continuous variables were assessed using an independent samples T-test. Chi-squared analyses were employed to report proportional differences in categorical variables. Where appropriate, comparisons of Likert scores (percentages) were performed using ordinal regression methods and reported as odds ratios. Analyses were performed on SPSS statistical software (v.27). P-value was considered significant if <0.05.
Results (if a Case Study enter NA)
162 physicians responded to the survey. 29 responses were excluded (work outside US, practice pathology, or in residency), resulting in 133 surveys for analysis. Preliminary analysis suggests that Likert scores were generally favorable (>3) for questions that asked whether the autopsy was of benefit to the clinical team, public health, and family closure. Also, Likert scores revealed that physicians experience barriers surrounding the autopsy in terms of understanding and comfort with tasks related to the autopsy.
Conclusion
Our study reveals that physicians are often unsure about the cause of their patients’ death, highlighting the continued importance of the autopsy in patient care. Barriers to autopsy use may include limited understanding of the procedure, how it is financed, and how to request an autopsy. Physicians also express discomfort with discussing autopsy with families. Education and specific training on conversations about the autopsy may increase use.

Abstract
Low dose radiation has been widely accepted by the radiation protection community as presenting a very low risk to human health, if any. Over-conservatism in optimisation principles and regulations have resulted in a disproportionate fear of radiation amongst the general public and government authorities alike, overlooking the great benefits nuclear science and techniques have brought to society as a whole. As such, the World Nuclear Association advocates for a recontextualisation of the radiation hazards with regards to low dose radiation, and a greater awareness as to the absence of any discernible effects associated with it.

Abstract
Background:Juvenile Localized Scleroderma (jLS) is a rare pediatric inflammatory disease of skin and underlying tissues that may cause significant functional impairment and disfigurement. Management approaches vary and an optimum treatment regimen is lacking. In 2012, a group of jLS researchers of Childhood Arthritis and Rheumatology Research Alliance (CARRA) proposed consensus treatment plans (CTPs), aimed to streamline the approach to care for jLS patients.Objectives:This study aimed to evaluate a large jLS patient cohort seen over a 21-year period in a single tertiary care pediatric hospital in the USA, in order to examine treatments utilized and determine parameters for systemic therapy initiation.Methods:This retrospective cohort study included jLS patients with disease onset in childhood (≤18-years of age) who were seen in rheumatology, dermatology, or combined rheumatology-dermatology clinics from 1999-2020, with ≤ 3 years of follow-up. Data on demographics, disease characteristics, therapies prescribed, and treatment trends were analyzed.Results:Of the 270 jLS patients identified, 101 fulfilled the inclusion criteria. The primary reason for exclusion was <3 years of follow-up. Selected demographic data and disease characteristics of patients are shown in Table 1. There were no statistically significant differences in most patient and disease characteristics between patients who received systemic treatment and those who did not. There were no significant differences in baseline laboratory values. The group treated with systemic therapy did have higher rates of extracutaneous involvement and had a higher proportion of patients with a generalized morphea phenotype.Table 1.Demographic and Disease CharacteristicsAll Patients(n=101)On Systemic Therapy(n=63)No Systemic Therapy(n=38)p valueAge-onset (Y), median (IQR)7.5 (6.4)9 (6)7 (4)NSAge-diagnosis(Y), median (IQR)9 (7.9)10 (6.7)9 (3.7)NSDiagnostic delay(M), median (IQR)10 (2.9)12 (13)7.5 (17)NSFollow-up (M), median (IQR)74 (69.3)65 (44.5)78 (47.7)NSSubtype Linear563917NS Face29209NS Circumscribed23419<0.0001 Mixed220NS Generalized201820.004Extracutaneous Involvement191810.001Clinic type Dermatology29227<0.0001 Rheumatology211920.003 Combined51429<0.0001The majority of patients who were on systemic immunomodulatory therapy were treated with methotrexate (59/63, 93.6 %) and/or systemic corticosteroids (21/63, 33 %). 5 patients were treated with hydroxychloroquine, 2 of which were also on methotrexate. 6 patients on methotrexate were either switched to or had mycophenolate mofetil added as concomitant therapy. The most common adverse effects observed in methotrexate-treated patients were gastrointestinal complaints (12/61, 19.7%) and fatigue (7/61, 11.5%). The median treatment duration was 50 months (IQR: 33.5). Patients were more likely to receive systemic therapy if they were followed in rheumatology or combined rheumatology-dermatology clinics as compared to dermatology clinics. Finally, 78% of patients with jLS received systemic treatment after 2013 (a year after publication of the CARRA jLS CTP) as compared to 55% of patients prior to 2013 (p < 0.05).Conclusion:This jLS cohort is one of the largest reported from a single center and reflects an increase in the use of systemic therapy since publication of CARRA CTPs in 2012. Further studies on long-term treatment outcomes and therapeutic approaches utilized when first-line treatment failures occur are warranted.References:[1]Li SC, Torok KS, Pope E, et al.

Abstract
BACKGROUND The existence of race and gender disparity has been described in numerous areas of medicine. The management of hepatocellular cancer is no different, but in no other area of medicine, is the treatment algorithm more complicated by local, regional, and national health care distribution policy. METHODS Multivariate logistic regression and Cox-regression were utilized to analyze the treatment of patients with hepatocellular cancer registered in SEER between 1999 and 2013 to determine the incidence and effects of racial and gender disparity. Odd ratios (OR) are relative to Caucasian males, SEER region, and tumor characteristics. RESULTS The analysis of 57,449 patients identified the minority were female (25.31%) and African-American (16.26%). All tumor interventions were protective (p < 0.001) with respect to survival. The mean survival for all registered patients was 13.01 months with conditional analysis, confirming that African-American men were less likely to undergo ablation, resection, or transplantation (p < 0.001). Women were more likely to undergo resection (p < 0.001). African-American women had an equivalent OR for resection but had a significantly lower transplant rate (p < 0.001). CONCLUSIONS Utilizing SEER data as a surrogate for patient navigation in the treatment of hepatocellular cancer, our study identified not only race but gender bias with African-American women suffering the greatest. This is underscored by the lack of navigation of African-Americans to any therapy and a significant bias to navigate female patients to resection potentially limiting subsequent access to definitive therapy namely transplantation.

Abstract
BACKGROUND Carbapenemase-producing organisms (CPO) have been largely responsible for the extensive spread of carbapenem resistance, and their prevalence is increasing in many parts of the world. AIM To evaluate clinical and molecular epidemiology and mortality associated with CPO among patients. METHODS All CPO from clinical and long-term healthcare surveillance cultures across Scotland in 2003-2017 were reviewed retrospectively. Polymerase chain reaction was used to detect genes coding for carbapenemases. A generalized linear mixed model was used to identify risk factors for mortality. FINDINGS In total, 290 individuals with CPO were identified. The overall incidence increased over time (P<0.001) from 0.02 to 1.38 per 100,000 population between 2003 and 2017. A total of 243 distinct CPO isolates were obtained from 269 isolations in 214 individuals with available metadata. The majority of the isolates were Enterobacterales (206/243, 84.8%), and Klebsiella pneumoniae (65/206, 31.6%) and Enterobacter cloacae (52/206, 25.2%) were the most common species. VIM (75/243, 30.9%) and NDM (56/243, 23.0%) were the most common carbapenemases. The crude 30-day mortality rate was 11.8% (25/211), while the case fatality rate was 5.7% (12/211). Age >60 years [adjusted odds ratio (aOR) 3.36, 95% confidence interval (CI) 1.06-10.63; P=0.033], presence of non-fermenters (aOR 4.88, 95% CI 1.64-14.47; P=0.005), and systemic infection or organ failure (aOR 4.21, 95% CI 1.38-12.81; P=0.032) were independently associated with 30-day mortality. CONCLUSION The incidence of CPO in Scotland is low but increasing. Awareness is required that inpatients aged >60 years, patients with systemic infection or organ failure, and patients presenting with non-fermenters are at higher risk of death from CPO.

Abstract
BACKGROUND Studies have demonstrated that there are sex disparities in the rate of liver transplantation. However, little is known statistically about whether this disparity is caused by liver compartment size, Model for End-Stage Liver Disease adjustments, or regional differences. METHODS We use retrospective data from the United Network for Organ Sharing Standard Treatment Analysis and Research data files for liver transplantation from 1995 through 2012. The final sample consists of 150,149 patients. These data contain information on all individuals who registered for the liver transplant waiting list as well as updated outcome data. Linear probability and logistic regression models were both used. RESULTS Women were 4.8 percentage points less likely to receive a transplant. Adjustment for race, weight, body mass index, region, education, and other characteristics attenuated the sex difference by roughly 19% (from 4.8 to 3.9 percentage points). The disparity was consistent across the 11 United Network for Organ Sharing allocation regions. Comparing the heaviest women to the lightest men, the disparity flipped. Pairwise comparisons between men and women of various sizes suggest that disparities in favor of men increase with the ratio of male-to-female size. CONCLUSION Our results document persistent sex disparity in liver transplantation, only 19% of which is explained by size differentials between men and women. Differences in rates of transplantation are increasing in the ratio of male-to-female height and weight, suggesting that some of the disparity is explained by differences in liver compartment size.

Abstract
Chordoma is a devastating rare cancer that affects one in a million people. With a mean-survival of just 6 years and no approved medicines, the primary treatments are surgery and radiation. In order to speed new medicines to chordoma patients, a drug repurposing strategy represents an attractive approach. Drugs that have already advanced through human clinical safety trials have the potential to be approved more quickly than de novo discovered medicines on new targets. We have taken two strategies to enable this: (1) generated and validated machine learning models of chordoma inhibition and screened compounds of interest in vitro. (2) Tested combinations of approved kinase inhibitors already being individually evaluated for chordoma. Several published studies of compounds screened against chordoma cell lines were used to generate Bayesian Machine learning models which were then used to score compounds selected from the NIH NCATS industry-provided assets. Out of these compounds, the mTOR inhibitor AZD2014, was the most potent against chordoma cell lines (IC50 0.35 µM U-CH1 and 0.61 µM U-CH2). Several studies have shown the importance of the mTOR signaling pathway in chordoma and suggest it as a promising avenue for targeted therapy. Additionally, two currently FDA approved drugs, afatinib and palbociclib (EGFR and CDK4/6 inhibitors, respectively) demonstrated synergy in vitro (CI50 = 0.43) while AZD2014 and afatanib also showed synergy (CI50 = 0.41) against a chordoma cell in vitro. These findings may be of interest clinically, and this in vitro- and in silico approach could also be applied to other rare cancers.

Abstract
Abstract
A collaborative study was conducted using a modified AOAC method (sugars in chocolate) for the determination of fructose, glucose, sucrose, and maltose in presweetened cereals by high pressure liquid chromatography (HPLC). Eight samples consisting of 6 products were analyzed in duplicate by the HPLC method and the AOAC Lane-Eynon method. The AOAC method was modified to use water-alcohol (1 + 1) and Sep-Pak C18 cartridges for sample cleanup. The HPLC results indicate precision comparable to the Lane-Eynon method and the chocolate method. The modified HPLC method has been adopted official first action.

Abstract
Namao virus (NV) is a sturgeon nucleocytoplasmic large DNA virus (sNCLDV) that can cause a lethal disease of the integumentary system in lake sturgeon Acipenser fulvescens. As a group, the sNCLDV have not been assigned to any currently recognized taxonomic family of viruses. In this study, a dataset of NV DNA sequences was generated and assembled as two non-overlapping contigs of 306 and 448 base pairs (bp) and then used to conduct a comprehensive systematics analysis using Bayesian phylogenetic inference for NV, other sNCLDV, and representative members of six families of the NCLDV superfamily. The phylogeny of NV was reconstructed using protein homologues encoded by nine nucleocytoplasmic virus orthologous genes (NCVOGs): NCVOG0022—mcp, NCVOG0038—DNA polymerase B elongation subunit, NCVOG0076—VV A18-type helicase, NCVOG0249—VV A32-type ATPase, NCVOG0262—AL2 VLTF3-like transcription factor, NCVOG0271—RNA polymerase II subunit II, NCVOG0274—RNA polymerase II subunit I, NCVOG0276—ribonucleotide reductase small subunit, and NCVOG1117—mRNA capping enzyme. The accuracy of our phylogenetic method was evaluated using a combination of Bayesian statistical analysis and congruence analysis. Stable tree topologies were obtained with datasets differing in target molecule(s), sequence length, and taxa. Congruent topologies were obtained in phylogenies constructed using individual protein datasets and when four proteins were used in a concatenated approach. The major capsid protein phylogeny indicated that ten representative sNCLDV form a monophyletic group comprised of four lineages within a polyphyletic Mimi-Phycodnaviridae group of taxa. Overall, the analyses revealed that Namao virus is a member of the Mimiviridae family with strong and consistent support for a clade containing NV and CroV as sister taxa.

Abstract
The neutron spin rotation (NSR) collaboration used parity-violating spin rotation of transversely polarized neutrons transmitted through a 0.5 m liquid helium target to constrain weak coupling constants between nucleons. While consistent with theoretical expectation, the upper limit set by this measurement on the rotation angle is limited by statistical uncertainties. The NSR collaboration is preparing a new measurement to improve this statistically-limited result by about an order of magnitude. In addition to using the new high-flux NG-C beam at the NIST Center for Neutron Research, the apparatus was upgraded to take advantage of the larger-area and more divergent NG-C beam. Significant improvements are also being made to the cryogenic design. Details of these improvements and readiness of the upgraded apparatus are presented. We also comment on how recent theoretical work combining effective field theory techniques with the 1/Nc expansion of QCD along with previous NN weak measurements can be used to make a prediction for dϕ/dz in 4He.
An experiment using the same apparatus with a room-temperature target was carried out at LANSCE to place limits on parity-conserving rotations from possible fifth-force interactions to complement previous studies. We sought this interaction using a slow neutron polarimeter that passed transversely polarized slow neutrons by unpolarized slabs of material arranged so that this interaction would tilt the plane of polarization and develop a component along the neutron momentum. The results of this measurement and its impact on the neutron-matter coupling gA2 from such an interaction are presented. The NSR collaboration is also preparing a new measurement that uses an upgraded version of the room-temperature target to be run on the NG-C beamline; and it is expected to constrain gA2 by at least two additional orders of magnitude for λc between 1 cm and 1 μm.

Abstract
Drugs of abuse, like alcohol, modulate gene expression in reward circuits and consequently alter behavior. However, the in vivo cellular mechanisms through which alcohol induces lasting transcriptional changes are unclear. We show that Drosophila Notch/Su(H) signaling and the secreted fibrinogen-related protein Scabrous in mushroom body (MB) memory circuitry are important for the enduring preference of cues associated with alcohol's rewarding properties. Alcohol exposure affects Notch responsivity in the adult MB and alters Su(H) targeting at the dopamine-2-like receptor (Dop2R). Alcohol cue training also caused lasting changes to the MB nuclear transcriptome, including changes in the alternative splicing of Dop2R and newly implicated transcripts like Stat92E. Together, our data suggest that alcohol-induced activation of the highly conserved Notch pathway and accompanying transcriptional responses in memory circuitry contribute to addiction. Ultimately, this provides mechanistic insight into the etiology and pathophysiology of alcohol use disorder.

This included 320 controls and 29 cardiovascular disease cases that were augmented with 98 additional known cases to yield a case cohort of 447 participants (320 controls, 127 cases). Biosamples from
DCCT
baseline, year 1, and closeout of
DCCT
, and 1 to 2 years post‐
DCCT
(
EDIC
years 1 and 2) were measured for markers of oxidative stress, including plasma myeloperoxidase, paraoxonase activity, urinary F
2α
isoprostanes, and its metabolite, 2,3 dinor‐8
iso
prostaglandin F
2α
. Following adjustment for glycated hemoblobin and weighting the observations inversely proportional to the sampling selection probabilities, higher paraoxonase activity, reflective of antioxidant activity, and 2,3 dinor‐8
iso
prostaglandin F
2α
, an oxidative marker, were significantly associated with lower risk of cardiovascular disease (−4.5% risk for 10% higher paraoxonase,
P
<0.003; −5.3% risk for 10% higher 2,3 dinor‐8
iso
prostaglandin F
2α
,
P
=0.0092). In contrast, the oxidative markers myeloperoxidase and F
2α
isoprostanes were not significantly associated with cardiovascular disease after adjustment for glycated hemoblobin. There were no significant differences between
DCCT
intensive and conventional treatment groups in the change in all biomarkers across time segments.
Conclusions
Heightened antioxidant activity (rather than diminished oxidative stress markers) is associated with lower cardiovascular disease risk in type 1 diabetes mellitus, but these biomarkers did not change over time with intensification of glycemic control.

Abstract
Fibrodysplasia ossificans progressiva (FOP) is a rare bone disease characterized by episodic events of heterotopic ossification (HO). All cases of FOP have been attributed to mutations in the ACVR1 gene that render the encoded BMP type I ALK2 receptor hypersensitive, resulting in the activation of BMP signaling, at inappropriate times in inappropriate locations. The episodic or sporadic nature of HO associated with FOP rests with the occurrence of specific 'triggers' that push the hypersensitive ALK2-FOP receptor into full signaling mode. Identification of these triggers and their mechanism of action is critical for preventing HO and its devastating consequences in FOP patients. Models of FOP, generated in Drosophila, are shown to activate the highly conserved BMP signaling pathway in both Drosophila cell culture and in developing tissues in vivo. The most common FOP mutation, R206H, in ALK2 and its synonymous mutation, K262H, in the orthologous Drosophila receptor Sax, abolish the ability of wild type receptors to inhibit BMP ligand-induced signaling and lead to ubiquitous pathway activation in both cases but with important differences. When expressed in Drosophila, human ALK2R206H exhibits constitutive signaling. SaxK262H on the other hand can elicit excessive signaling similar to that observed for ALK2R206H in mammalian systems in vivo. For example, hyperactive signaling mediated by SaxK262H is triggered by an increase in ligand or in type II receptors. Interestingly, while the constitutive nature of ALK2R2026H in Drosophila requires activation by the type II receptor, it does not require its ligand binding domain. The differences exhibited by the two Drosophila FOP models enable a valuable comparative analysis poised to reveal critical regulatory mechanisms governing signaling output from these mutated receptors. Modifier screens using these Drosophila FOP models will be extremely valuable in identifying genes or compounds that reduce or prevent the hyperactive BMP signaling that initiates HO associated with FOP.

Abstract
Using a novel set of 12 microsatellites, a captive, adult female swellshark Cephaloscyllium ventriosum that produced five pups via parthenogenesis is described; naturally occurring parthenogenesis has been observed in every vertebrate class with the exception of mammals. As demonstrated in this study, a captive environment is ideal for long-term monitoring of animals under controlled conditions, and easily allows the detection of particular facets of their biology.
