Abstract
In 2021, airplanes consumed nearly 250 million tons of fuel, equivalent to almost 10.75 exajoules. Anticipated growth in air travel suggests increasing fuel consumption. In January 2022, demand surged by 82.3%, as per the International Air Transport Association. In tackling aviation emissions, governments promote synthetic e-fuels to cut carbon. Sustainable aviation fuel (SAF) production increased from 1.9 million to 15.8 million gallons in six years. Although cost of kerosene produced with carbon dioxide from direct air capture (DAC) is several times higher than the cost of conventional jet fuel, its projected production cost is expected to decrease from $104-$124/MWh in 2030 to $60-$69/MWh in 2050. Advances in DAC technology, decreasing cost of renewable electricity, and improvements in FT technology are reasons to believe that the cost of e-kerosene will decline. This review describes major e-kerosene synthesis methods, incorporating DAC, hydrogen from water electrolysis, and hydrocarbon synthesis via the Fischer-Tropsch process. The importance of integrating e-fuel production with renewable energy sources and sustainable feedstock utilization cannot be overstated in achieving carbon emission circularity. The paper explores the concept of power-to-liquid (PtL) pathways, where renewable energy is used to convert renewable feedstocks into e-fuels. In addition to these technological improvements, carbon pricing, government subsidies, and public procurement are several policy initiatives that could help to reduce the cost of e-kerosene. Our review provides a comprehensive guide to the production pathways, technological advancements, and carbon emission circularity aspects of aviation e-fuels. It will provide a valuable resource for researchers, policymakers, industry stakeholders, and the general public interested in transitioning to a sustainable aviation industry.

Abstract
Peroxisomes are organelles with crucial functions in oxidative metabolism. To correctly target to peroxisomes, proteins require specialized targeting signals. A mystery in the field is the sorting of proteins that carry a targeting signal for peroxisomes and as well as for other organelles, such as mitochondria or the endoplasmic reticulum (ER). Exploring several of these proteins in fungal model systems, we observed that they can act as tethers bridging organelles together to create contact sites. We show that in Saccharomyces cerevisiae this mode of tethering involves the peroxisome import machinery, the ER-mitochondria encounter structure (ERMES) at mitochondria and the guided entry of tail-anchored proteins (GET) pathway at the ER. Our findings introduce a previously unexplored concept of how dual affinity proteins can regulate organelle attachment and communication.

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
Most children with high-risk Langerhans cell histiocytosis (LCH) have BRAFV600E mutation. BRAFV600E alleles are detectable in myeloid mononuclear cells at diagnosis but it is not known if the cellular distribution of mutation evolves over time. Here, the profiles of 16 patients with high-risk disease were analyzed. Two received conventional salvage chemotherapy, 4 patients on inhibitors were tracked at intervals of 3 to 6 years, and 10 patients, also given inhibitors, were analyzed more than 2 years after diagnosis. In contrast to the patients responding to salvage chemotherapy who completely cleared BRAFV600E within 6 months, children who received inhibitors maintained high BRAFV600E alleles in their blood. At diagnosis, mutation was detected predominantly in monocytes and myeloid dendritic cells. With time, mutation switched to the T-cell compartment, which accounted for most of the mutational burden in peripheral blood mononuclear cells, more than 2 years from diagnosis (median, 85.4%; range, 44.5%-100%). The highest level of mutation occurred in naïve CD4+ T cells (median, 51.2%; range, 3.8%-93.5%). This study reveals an unexpected lineage switch of BRAFV600E mutation in high-risk LCH, which may influence monitoring strategies for the potential withdrawal of inhibitor treatment and has new implications for the pathogenesis of neurodegeneration, which occurred in 4 patients.

Abstract
BACKGROUND Procedural anxiety was anticipated in children 5-11 years during the COVID-19 vaccine rollout in Victoria, Australia, as children in this age group receive few routine vaccines. Therefore, the Victorian state government designed a tailored, child-friendly vaccine program. This study aimed to assess parental satisfaction with elements of the bespoke vaccination pathway. METHODS The Victorian government and state-run vaccination hubs in Victoria facilitated an online immunisation plan to help parents identify their child's support needs, and utilised experienced paediatric staff and additional supports for children with severe needle distress and/or disability. All parents/guardians of children 5-11 years who received a COVID-19 vaccine in a vaccination hub were sent a 16-item feedback survey via text message. RESULTS Between 9 February and 31 May 2022 there were 9203 responses; 865 children (9.4%) had a first language other than English, 499 (5.4%) had a disability or special needs, and 142 (1.5%) were Aboriginal or Torres Strait Islander. Most parents (94.4%; 8687/9203) rated their satisfaction with the program as very good or excellent. The immunisation plan was used by 13.5% (1244/9203) of respondents, with usage more common for Aboriginal or Torres Strait Islander children (26.1%; 23/88) or families with a first language other than English (23.5%; 42/179). The child-friendly staff (88.5%, 255/288) and themed environment (66.3%, 191/288) were the most valued measures for vaccination. Additional support measures were required by 1.6% (150/9203) of children in the general population and 7.9%, (17/261) of children with a disability and/or special needs. CONCLUSION A tailored COVID-19 vaccination program for children 5-11 years, with additional support for children with severe needle distress and/or disability, had high parental satisfaction. This model could be utilised for COVID-19 vaccination in pre-school children and for routine childhood vaccination programs to provide optimal support to children and their families.

Abstract
Abstract
Oncogenic alterations of the RAS/RAF/MEK/ERK signaling pathway drives growth of over 40% of human tumors, frequently due to activating mutations of components of the pathway, such as RAS or BRAF. Targeting the pathway using BRAF inhibitors (BRAFi) in combination with MEK inhibitors (MEKi) is now the standard of care for metastatic melanoma patients harboring the BRAF(V600E) mutation. However, effective targeted therapies are lacking for most cancers driven by other pathway alterations, including those with RAS activating mutations. The effectiveness of current clinical BRAFi relies on the fact that they bind selectively and inhibit the mutationally activated monomeric form of the BRAF(V600E) kinase in tumors but not wild-type BRAF in normal tissue where BRAF signals in its dimeric form. Yet, the development of adaptive resistance, frequently due to RAF dimerization, limits BRAFi therapeutic effectiveness. Another class of BRAFi equipotent for both monomeric and dimeric BRAF have been developed, but are predicted to have lower therapeutic index due to inhibition of dimeric wild-type BRAF in normal tissues as well. Recently, we identified and characterized a novel class of BRAFi that preferentially binds and inhibits dimeric BRAF over monomeric BRAF(V600E) (i.e. RAF dimer-selective inhibitors). Furthermore, we rationally designed a combinatorial approach utilizing a BRAF monomer-selective plus a BRAF dimer-selective inhibitor plus a MEK inhibitor, that potently disrupts the BRAF/MEK complex, to maximally inhibit BRAF(V600E) signaling in tumors while retaining a broad therapeutic index. This triple combination potently suppressed tumor growth of multiple BRAF(V600E) colorectal cancer and melanoma models resistant to the current clinical BRAFi and MEKi combinations both in vitro and in vivo. To design effective therapeutic approaches for RAS-mutated tumors, we also assessed the effectiveness of RAF and MEK inhibitors belonging to diverse biochemical and structural classes, either alone or in combination in RAS-mutant tumor models and normal cells with wild-type RAS signaling. We found that RAF dimer-selective inhibitors potently antagonized MAPK signaling and growth in various RAS mutant cancer models as compared to normal cells. We found further that RAF and MEK inhibitor combinations belonging to certain biochemical classes resulted in more potent MAPK suppression in RAS-mutant tumor as compared to wild-type RAS normal cells (“therapeutic synergy”) and should be prioritized for clinical testing. In contrast, those combinations which are more potent in normal over tumor cells (“adverse synergy”) are unlikely to be clinically successful. Thus, rationally designed combinations of selected RAFi and MEKi, based on their distinct biochemical properties, can uncover new therapeutic opportunities tailored for more effective targeting of BRAF or RAS mutant tumors.

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
Introduction/Objective
Anaplastic lymphoma kinase-positive large B-cell lymphoma (ALK-positive LBCL) is a rare, aggressive type of non-Hodgkin’s B-cell lymphoma with characteristic rearrangements and overexpression of ALK. Diagnosis of ALK-positive LBCL is challenging because of its rarity and uncharacteristically low expression of B- lineage antigens usually needed for diagnosis of B-cell lymphomas. In this report, we describe a case of ALK-positive large B cell lymphoma involving epidural soft tissue in a young adult.
Methods/Case Report
29 year old presented to emergency department with a two week history of back pain and a three day history of worsening numbness and weakness in the lower extremities. MRI of the thoracic spine showed an epidural soft tissue mass posterior to T5, T6 and T7 vertebral bodies with abnormal signal in the T6 spinous process. Histological examination from the epidural mass revealed sheets of atypical lymphoid cells with abundant pale cytoplasm and round vesicular nuclei with prominent single to occasional multiple nucleoli. Immunohistochemical stains demonstrated neoplastic cell positivity for ALK, VS38c, CD138, EMA, MUM1, CD45, PAX5 and MCK. They were negative for CD3, CD20, CD19, CD79a, CD30, CD2, CD117, SOX10, HMB45, cytokeratin, synaptophysin and chromogranin. These overall findings were consistent with ALK-positive large B-cell lymphoma.
Results (if a Case Study enter NA)
NA.
Conclusion
ALK-positive large B-cell lymphoma is a non-Hodgkin lymphoma associated with high morbidity and mortality. Absence of reliable B-cell marker expression in this B-cell lymphoma requires recognition of morphological findings to order confirmatory testing such as immunohistochemical stains for CD138 and ALK. This particular case also showed an unusual anatomic presentation in epidural tissue.

Abstract
The efficient removal of pharmaceutical pollutants presents a great challenge for the conventional sewage treatment system. Herein, we document the nanosheets assembled 3D hierarchical Fe3O4 hollow microspheres co-modified by Ag and g-C3N4 quantum dots (Ag/CNQDs@Fe3O4) for efficient degradation of two classic anticancer drugs, i.e., capecitabine (CAP) and 5-fluorouracil (5-FLU) under visible light in 1 h. Benefiting from the unique hierarchically hollow structure, the intrinsic strengths of each component and their interactions, synergistic reinforcing mechanism is constructed, furnishing more accessible reactive places, promoting the diffusion of pollutants/oxidants, improving charge separation ability, and raising light utilization rate. Consequently, Ag/CNQDs@Fe3O4 can not only show superior photocatalytic properties, but also greatly boost PMS activation to yield sufficient oxidative radicals. More notably, the studied system also features excellent stability and strong tolerance to real water samples, and maintains appreciable performance even under natural sunlight illumination. The predominant active species, possible ADs decomposition pathways, and underlying reaction mechanism for the Ag/CNQDs@Fe3O4/PMS/vis system are thoroughly explored. This work presents significant advancement in enabling an integrated technology of PMS and photocatalysis to realize its great potential in environment restoration.

Abstract
Background Point-of-care ultrasound (POCUS) has been previously studied in cardiac arrest, without definitive markers for futile resuscitation efforts identified. Intracardiac thrombus during cardiac arrest has not been systematically studied. Our objective was to describe the incidence of intracardiac thrombus and spontaneous echo contrast found during cardiac arrest. Methods A two hospital, retrospective, observational cohort study of 56 cardiac arrest patients who were assessed with POCUS (between January 1st, 2017 to April 30th, 2020). Eligible studies were reviewed for echocardiographic findings (e.g. presence of intracardiac thrombus or spontaneous echo contrast), baseline patient demographics, cardiac arrest-related data, and clinical outcomes. Primary outcome was in-hospital mortality. Results Fifty-six intra-arrest POCUS echocardiograms were identified (out of 738 out-of-hospital cardiac arrests). The median patient age was 63 years (interquartile range [IQR]: 51–72), with 25% female patients, and median Charlson Comorbidity Index score of 4 (IQR: 2–6). The incidence of intracardiac thrombus was 21 out of 56 patients (38%). Time-to-new thrombus formation during cardiac arrest was approximately 6 minutes (IQR: 2-–8). All patients with intracardiac thrombus during cardiac arrest had termination of resuscitation. Conclusions Intracardiac thrombus is potentially common during out-of-hospital cardiac arrests and was observed more frequently in those in whom termination of resuscitation was recommended. However, this is only hypothesis-generating at this time, and further study is required to determine if the presence of intracardiac thrombus may be used as a potential marker of resuscitation futility.

Abstract
Introduction
For older adults, feeling subjectively younger is associated with improvements in cognition, subjective well-being and depressive symptoms. Positive psychiatry is the field that focuses on patient strengths and the promotion of positive outcomes, rather than just mitigation of illness. Younger subjective age may be a useful measure of successful aging, but little is known about how subjective age is associated with positive psychosocial characteristics.
Objectives
Our objective is to characterize how subjective age is related validated positive psychosocial measures, with the goal of better understanding the determinants of successful aging.
Methods
The Successful Aging Evaluation (SAGE) longitudinal study recruited over 1,300 community-dwelling residents of San Diego County, CA, from age 21 to over 100. A single-item question asked “How old/young do you feel?” We used spearman correlations to assess the relationship between subjective age and validated positive psychosocial scales such as the Self-Rated Successful Aging, Life Orientation Test, Personal Mastery Scale, Connor-Davidson Resilience Scale, Satisfaction with Life Scale, Adult Hope Scale, and Social Support Index.
Results
Mean chronological age was 65.5, and mean subjective age was 53.6. Mean age discrepancy was 11.5 years. Younger subjective age was positively associated with most of the positive psychosocial characteristics measured, including self-rated successful aging, optimism, personal mastery, resilience, curiosity, hope, and social support.
Conclusions
There is a growing movement within psychiatry to understand the positive characteristics that lead to successful aging. This is one of the first studies demonstrating younger age identities are associated with positive psychosocial characteristics and successful aging.
Disclosure

Abstract
BACKGROUND Posterior ankle impingement syndrome (PAIS) is a common and debilitating condition, commonly affecting people who participate in activities that involve repetitive ankle plantarflexion. The relationship between clinical and imaging findings in PAIS has not been established. PURPOSE To investigate the relationship between clinical and imaging features in PAIS by reviewing the literature comparing symptomatic patients to asymptomatic controls. MATERIAL AND METHODS A systematic literature search was performed to identify all English-language articles that compared imaging features in patients diagnosed with PAIS to imaging in an asymptomatic control group. RESULTS A total of 8394 articles were evaluated by title and abstract, and 156 articles were read in full text. No articles compared imaging findings to an asymptomatic control group, thus no articles met the inclusion criteria. CONCLUSION This systematic review found no published research that compared the imaging findings of people diagnosed with PAIS to asymptomatic people. Until this information is available, imaging features in people with posterior ankle impingement should be interpreted with caution.

Abstract
Background Stigmatization may prompt gay, bisexual, queer and other men who have sex with men (GBQMSM) to avoid or delay HIV testing. There has been little attention to GBQMSMs’ perspectives about how stigma may influence their decisions about whether, where, and how often to get tested for HIV. Methods We conducted nine focus groups with 64 adult GBQMSM in Metropolitan Detroit, including HIV-negative men and people living with HIV (PLWH). Data were thematically analyzed deductively and inductively in three rounds. Results Three themes emerged regarding whether to get tested: (1) Perceived promiscuity, risk perceptions and HIV testing; (2) Fearing sexual rejection; and (3) Fearing friend and family member distancing and rejection. Themes concerning where to get tested included: (4) Conflating HIV testing and diagnosis; and (5) Seeking privacy and safety at specialized services. As for how often to get tested, themes included: (6) Reducing contact with healthcare providers due to intersectional stigma; (7) Responsibility and regular testing; and (8) HIV stigma and testing as routine care. Black participants articulated themes (3), (4), and (6) with greater frequency than other participants. Framing HIV testing as a personal responsibility may have created a “new stigma,” with unintended consequences not observed with “routine healthcare” messaging. Conclusions GBQMSMs’ perspectives indicate the potential for new foci for HIV testing promotion interventions based on stigma-related issues that they deem important. There is a need for interventions to challenge the “promiscuity” stereotype, and to reduce the sexual stigmatization of GBQMSM living with HIV/AIDS—especially online. Provider stigma requires both intervention and continued availability of specialized services. Future stigma-reduction interventions for Black GBQMSM could focus on building family support/acceptance, awareness of multiple testing options, and integrating LGBTQ-related issues into initiatives for racial justice in health care.

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.

Abstract
OBJECTIVE To report the prevalence of MRI features commonly associated with posterior ankle impingement syndrome in elite ballet dancers and athletes and to compare findings between groups. MATERIALS AND METHODS Thirty-eight professional ballet dancers (47.4% women) were age- and sex-matched to 38 elite soccer or cricket fast bowler athletes. All participants were training, playing, and performing at full workload and underwent 3.0-T standardised magnetic resonance imaging of one ankle. De-identified images were assessed by one senior musculoskeletal radiologist for findings associated with posterior ankle impingement syndrome (os trigonum, Stieda process, posterior talocrural and subtalar joint effusion-synovitis, flexor hallucis longus tendon pathology and tenosynovitis, and posterior ankle bone marrow oedema). Imaging scoring reliability testing was performed. RESULTS Posterior talocrural effusion-synovitis (90.8%) and subtalar joint effusion-synovitis (93.4%) were common in both groups, as well as the presence of either an os trigonum or Stieda process (61.8%). Athletes had a higher prevalence of either os trigonum or Stieda process than dancers (74%, 50% respectively, P = 0.03). Male athletes had a higher prevalence of either os trigonum or Stieda process than male dancers (90%, 50% respectively, P = 0.01), or female athletes (56%, P = 0.02). Posterior subtalar joint effusion-synovitis size was larger in dancers than athletes (P = 0.02). Male and female dancers had similar imaging findings. There was at least moderate interobserver and intraobserver agreement for most MRI findings. CONCLUSION Imaging features associated with posterior impingement were prevalent in all groups. The high prevalence of os trigonum or Stieda process in male athletes suggests that this is a typical finding in this population.

IntroductionPositive psychiatry is the science and practice of psychiatry seeking to promote overall well-being and understand the “positive” aspects of the patient’s life, such as resilience, social connections, and meaning and values in life. While positive psychiatry research has recently blossomed, the field lacks practical ways to integrate these overarching principles into clinical practice. Life review interventions are commonly used in palliative care, spiritual care, and geriatrics, and involve a healthcare team member interviewing a patient about their life.ObjectivesOur objective is to describe the implementation of a positive psychiatry-informed life story review initiative into medical education, with the goal of creating a structure for medical trainees to see the larger context of patients’ health, understand how past experiences influence current values, and improve patients’ overall well-being.MethodsFirst- and third-year students at Alpert Medical School of Brown University are required to participate in at least one strengths-based life review with a patient in the community or inpatient setting, transcribe the story, and integrate the story into the electronic health record.ResultsPreliminary results demonstrate high acceptability and perceived development of patient-centered competencies, such as understanding patients as more complete human beings. While this is a low cost and sustainable intervention, barriers include buy-in from medical educators, hospital administrators, and trainees.ConclusionsTo our knowledge, this is one of the first positive psychiatry-informed interventions to be implemented into the required medical curricula. Life story reviews may allow providers to understand the “positive” aspects of patients’ lives and understand their patients better as people.

Abstract
Treatment-related toxicity is an important component in non-small cell lung cancer (NSCLC) management decision-making. Our aim was to evaluate and compare the toxicity rates of curative and palliative radiotherapy with and without chemotherapy. This meta-analysis provides better quantitative estimates of the toxicities compared to individual trials. A systematic review of randomised trials with > 50 unresectable NSCLC patients, treated with curative or palliative conventional radiotherapy (RT) with or without chemotherapy. Data was extracted for oesophagitis, pneumonitis, cardiac events, pulmonary fibrosis, myelopathy and neutropenia by any grade, grade ≥ 3 and treatment-related deaths. Mantel–Haenszel fixed-effect method was used to obtain pooled risk ratio. Forty-nine trials with 8609 evaluable patients were included. There was significantly less grade ≥ 3 acute oesophagitis (6.4 vs 22.2%, p < 0.0001) and any grade oesophagitis (70.4 vs 79.0%, p = 0.04) for sequential CRT compared to concurrent CRT, with no difference in pneumonitis (grade ≥ 3 or any grade), neutropenia (grade ≥ 3), cardiac events (grade ≥ 3) or treatment-related deaths. Although the rate of toxicity increased with intensification of treatment with RT, the only significant difference between treatment regimens was the rate of oesophagitis between the use of concurrent and sequential CRT. This can aid clinicians in radiotherapy decision making for NSCLC.

Abstract
Abstract
Introduction/Objective
The role of Herpes Simplex Virus (HSV) virus in the development of lymphomas is unclear and poses a diagnostic challenge along with limited literature explaining the relationship between HSV and Anaplastic large-cell lymphoma (ALCL).
Methods
A 26-year-old female admitted for intractable fever (103.7 F), chills, and dysuria; her urine analysis was suggestive of a mild urinary tract infection. During the admission, she developed abdominal pain with subsequent CT- scan showing thickening of the gallbladder and possible cholecystic fluid. Her liver function tests were: albumin 2.8 g/dL, AST 394 U/L, ALT 303 U/L, ALP 156 U/L, total bilirubin 0.3 INR 1. A subsequent Magnetic Resonance Cholangiopancreatography (MRCP) showed heterogeneous enhancement pattern of the liver without any masses following which she underwent cholecystectomy, during which her liver was abnormal along with an enlarged peri- cholic lymph node. Intraoperative biopsy of the liver showed patchy hepatocyte necrosis and occasional hepatocytes with ground-glass nuclei. The morphologic features were suggestive for Herpes Simplex Virus (HSV) hepatitis, and an HSV immunohistochemical stain confirmed this diagnosis. Removal of the lymph node showed a sinusoidal infiltrate of atypical lymphohistiocytic cells with abundant pale cytoplasm and large moderately irregular nuclei and occasional prominent amphophilic nucleoli. A few “hallmark”-like cells with curved nuclei were noted with rare mitosis. A panel of adequately controlled immunohistochemical stains showed positivity for CD4, CD30 (variable), and CD45. CD2, CD3, CD5, CD7, CD8, CD10, CD15, CD20, CD68 (positive in adjacent macrophages), BCL2, ALK1 were negative.
Results
Flow cytometry was negative for a neoplastic leukocyte population with a polytypic B-cell population. Taken together, a diagnosis of ALK1 negative, ALCL was made. A subsequent CT scan revealed borderline enlarged para- aortic lymph nodes along with an increased number of non-enlarged lymph nodes in the bilateral axillary, mediastinal, lower neck, and subpectoral regions. A bone marrow biopsy performed was negative for lymphoma.
Conclusion
Off note, her hepatitis serology panel, CMV, and HIV screens were negative. Thus, with her unusual presenting symptoms and no signs of malignancy led to numerous workups, which further led to an infectious cause, however, the patient was ultimately discovered to have an occult ALCL.

Abstract
Abstract
Introduction/Objective
Natural Killer cells (NK-cells) malignancies are extremely rare and the two NK-cell disorders involving the peripheral blood and bone marrow include chronic lymphoproliferative disorder of NK-cells (CLPDNK) and aggressive NK-cell leukemia (ANKL). ANKL is EBV associated with a prevalence in Asian adults and a fulminant clinical course leading to death within 2 months.
Methods
A 76-year-old female with a history of iron deficiency anemia presented for evaluation of lymphocytosis (78 TH/mm) and negative EBV with extreme fatigue, weight loss, and worsening weakness from the past 8 months.
Results
The peripheral and bone marrow aspirate showed an increase in granular lymphocytes with bland nuclei and abundant pale-staining cytoplasm containing fine to coarse azurophilic granules with no evidence of nuclear atypia. Flow cytometry demonstrated an atypical lymphocytic cell population comprising >50% of total marrow and peripheral blood lymphocytes demonstrating loss of CD56 and diminished CD7 expression. The analysis showed atypical lymphocytes with the following immunophenotype: CD2, CD8 (the majority, at least 75%),CD7 (dim), CD38, CD11c (subset) with no expression of CD3, CD5, CD4, CD56, or CD11c. Flow cytometry is important as it helps in the phenotypic detection of aberrancy. A broad panel of immunohistochemical stains revealed scattered positivity for CD3, CD4, CD7, CD8, TIA-1, granzyme, perforin, and tryptase and negative for CD56 and CD57. Our top differential with a similar clinical course included T-cell large granular lymphocytic leukemia which is characterized by a clonal proliferation of mature cytotoxic T cells and also has an indolent course. They show CD3 positivity by flow cytometry along with co-expression of NK cell-associated markers (CD16 and CD57), and variable expression of other pan T cell markers such as CD2, CD5, CD7. It is found incidentally in patients having cytopenias with a persistent increase in circulating mature NK-cells. Of note, the PET scan revealed splenomegaly with no other significant findings.The patient was started on steroids and is currently doing well.
Conclusion
Thus, overall morphologic, immunophenotypic, and molecular results with negative expression of surface or cytoplasmic CD3 as well as the absence of TCR expression were most consistent with CLPD-NK with an unusual expression of CD57 expression detected in flow cytometry.

Abstract
BACKGROUND This study aimed to determine the impact of preoperative exposure to intravenous contrast for CT and the risk of developing postoperative acute kidney injury (AKI) in patients undergoing major gastrointestinal surgery. METHODS This prospective, multicentre cohort study included adults undergoing gastrointestinal resection, stoma reversal or liver resection. Both elective and emergency procedures were included. Preoperative exposure to intravenous contrast was defined as exposure to contrast administered for the purposes of CT up to 7 days before surgery. The primary endpoint was the rate of AKI within 7 days. Propensity score-matched models were adjusted for patient, disease and operative variables. In a sensitivity analysis, a propensity score-matched model explored the association between preoperative exposure to contrast and AKI in the first 48 h after surgery. RESULTS A total of 5378 patients were included across 173 centres. Overall, 1249 patients (23·2 per cent) received intravenous contrast. The overall rate of AKI within 7 days of surgery was 13·4 per cent (718 of 5378). In the propensity score-matched model, preoperative exposure to contrast was not associated with AKI within 7 days (odds ratio (OR) 0·95, 95 per cent c.i. 0·73 to 1·21; P = 0·669). The sensitivity analysis showed no association between preoperative contrast administration and AKI within 48 h after operation (OR 1·09, 0·84 to 1·41; P = 0·498). CONCLUSION There was no association between preoperative intravenous contrast administered for CT up to 7 days before surgery and postoperative AKI. Risk of contrast-induced nephropathy should not be used as a reason to avoid contrast-enhanced CT.

Abstract
Background:Efficacy observed in controlled trials may not reflect RW effectiveness, given documented differences in patient populations and management.1Objectives:This study aimed to assess disease measures over time as measured in a trial setting (AMPLE) and in a separate RW observational setting, both among patients with RA treated with abatacept.Methods:The RW cohort comprised retrospective patient-level data abstracted by 31 community rheumatologists for adult RA patients treated with abatacept who had an anti-cyclic citrullinated peptide-2 titer ≥250 AU/mL. AMPLE was a phase III, randomized controlled trial of RA patients treated with abatacept that assessed disease measures over a 2-year follow-up. Data included demographics, treatments, labs, and disease measures (tender and swollen joint counts (TJC, SJC), C-reactive protein (CRP), American College of Rheumatology-20 (ACR20) and ACR50 at baseline and 3 and 6 months) and were summarized descriptively. Disease measures were evaluated across AMPLE and RW cohorts.Results:Of the 291 RW patients and 318 AMPLE patients, the majority were female (70%, 81%), white (72%, 81%), and RF-positive (91%, 76%), respectively (Table 1). The mean ages at abatacept initiation were 54.7 and 51.4 years old in RW and AMPLE, respectively. Concomitant corticosteroids (45%, 65%) and methotrexate (62%, 100%) were common in RW and AMPLE, respectively. All patients in AMPLE were biologic naïve, whereas 83% of RW patients had prior biologic use. AMPLE administered abatacept subcutaneously (SC), while 37% of RW patients received abatacept SC. Patients had median SJC and TJC of 6 and 8 in RW and 13 and 22 in AMPLE at abatacept initiation, respectively (Table 2). SJC (TJC) improved a median of 65% (60%) and 68% (66%) at 3 months and 75% (67%) and 76% (75%) at 6 months in RW and AMPLE, respectively (Fig 1). The majority of patients achieved ACR20 at 3 months (79% and 60%) and 6 months (88% and 66%) in RW and AMPLE, respectively, while 58% and 32% achieved ACR50 at 3 months and 67% and 45% at 6 months, respectively (Fig 2).Table 1:Patient Characteristics.RW cohort(n=291)AMPLE cohort(n=318)Female (n, %)205 (70%)259 (81%)White (n, %)209 (72%)257 (81%Age at abatacept initiation, years (mean, SD)54.7 (14.8)51.4 (12.6)RF-positive* (n, %)249 (91%)240 (76%)Concomitant medications (n, %) Corticosteroids†132 (45%)207 (65%) Methotrexate179 (62%)318 (100%)Prior biologic use (n, %)241 (83%)0 (0%)Route of administration (n, %) Intravenous183 (63%)0 (0%) Subcutaneous108 (37%)318 (100%)LEGEND: *among 274 with known RF status;†corticosteroids in AMPLE cohort at any time in the 2-year study periodTable 2.Changes in Disease Activity.RW cohort(n=291)AMPLE cohort(n=318)SJC (median) Baseline value613 3-month value24 6-month value13TJC (median) Baseline value822 3-month value37 6-month value25CRP, mg/dL (mean) Baseline value1.081.6 3-month value0.470.8 6-month value0.300.8ACR20 achieved (n, %) 3-month value194 (79%)191 (60%) 6-month value78 (88%)209 (66%)ACR50 achieved (n, %) 3-month value144 (58%)103 (32%) 6-month value60 (67%)144 (45%)LEGEND: values soonest after 3 months and value between 6-9 months used for RW cohort; values at days 85 and 197 used for AMPLE cohort.Conclusion:Despite differences in patient characteristics, improvements in SJC and TJC, as well as high rates of ACR20 and ACR50, were observed in both trial setting and RW settings.

Abstract
INTRODUCTION UK and European guidelines recommend consideration of a self-expandable metallic stent (SEMS) as an alternative to emergency surgery in left-sided colonic obstruction. However, there is no clear consensus on stenting owing to concern for complications and long-term outcomes. Our study is the first to explore SEMS provision across England. METHODS All colorectal surgery department leads in England were contacted in 2018 and invited to complete an objective multiple choice questionnaire pertaining to service provision of colorectal stenting (including referrals, time, location and specialty). RESULTS Of 182 hospitals contacted, 79 responded (24 teaching hospitals, 55 district general hospitals). All hospitals considered stenting, with 92% performing stenting and the remainder referring. The majority (93%) performed fewer than four stenting procedures per month. Most (96%) stented during normal weekday hours, with only 25% stenting out of hours and 23% at weekends. Compared with district general hospitals, a higher proportion of teaching hospitals stented out of hours and at weekends. Stenting was performed in the radiology department (64%), the endoscopy department (44%) and operating theatres (15%), by surgeons (63%), radiologists (60%) and gastroenterologists (48%). A radiologist was present in 66% of cases. Of 14 hospitals that received referrals, 3 had a protocol, 3 returned patients the same day and 4 returned patients for management in the event of failure. CONCLUSIONS All responding hospitals in England consider the use of SEMS in colonic obstruction. Nevertheless, there is great variation in stenting practices, and challenges in terms of access and expertise. Centralisation and regional referral networks may help maximise availability and expertise but more work is needed to support this.

Abstract
The Canadian healthcare system serves as an example of equity and federal service to citizens across the world. However, it is not without its challenges. Prosthetic coverage across Canada is highly variable and largely unable to provide equal coverage for Canadian persons living with amputation. Many persons with limb loss are forced to rely upon personal resources, fundraising, or the charity of non-governmental organizations in order to meet this basic healthcare need. This disparity in the Canadian healthcare system is unusual and largely undescribed in the literature. We thus explore the nature of Canadian healthcare prosthetic coverage across Canada, investigating the variability in coverage, presence of prosthetic coverage policies, clarity of policy, eligibility criteria, and interval of prosthetic replacement. Our findings highlight potential areas for improvement within current Canadian healthcare policy.

Abstract
The RING finger protein TRAIP protects genome integrity and its mutation causes Seckel syndrome. TRAIP encodes a nucleolar protein that migrates to UV-induced DNA lesions via a direct interaction with the DNA replication clamp PCNA. Thus far, mechanistically how UV mobilizes TRAIP from the nucleoli remains unknown. We found that PCNA binding is dispensable for the nucleolus-nucleoplasm shuttling of TRAIP following cell exposure to UV irradiation, and that its redistribution did not rely on the master DNA damage kinases ATM and ATR. Interestingly, I-PpoI-induced ribosomal DNA damage led to TRAIP exclusion from the nucleoli, raising the possibility that active ribosomal DNA transcription may underlie TRAIP retention in the nuclear sub-compartments. Accordingly, chemical inhibition of RNA polymerase I activity led to TRAIP diffusion into the nucleoplasm, and was coupled with marked reduction of DNA/RNA hybrids in the nucleoli, suggesting that TRAIP may be sequestered via binding to nucleic acid structures in the nucleoli. Consistently, cell pre-treatment with DNase/RNase effectively released TRAIP from the nucleoli. Taken together, our study defines a bipartite mechanism that drives TRAIP trafficking in response to UV damage, and highlights the nucleolus as a stress sensor that contributes to orchestrating DNA damage responses.

Abstract
Synthetic hydrogels are investigated extensively in tissue engineering for their tunable physicochemical properties but are bioinert and lack the tissue-specific cues to produce appropriate biological responses. To introduce tissue-specific biochemical cues to these hydrogels, we have developed a modular hydrogel cross-linker, poly(glycolic acid)-poly(ethylene glycol)-poly(glycolic acid)-di(but-2-yne-1,4-dithiol) (PdBT), that can be functionalized with small peptide-based cues and large macromolecular cues simply by mixing PdBT in water with the appropriate biomolecules at room temperature. Cartilage- and bone-specific PdBT macromers were generated by functionalization with a cartilage-associated hydrophobic N-cadherin peptide, a hydrophilic bone morphogenetic protein peptide, and a cartilage-derived glycosaminoglycan, chondroitin sulfate. These biofunctionalized PdBT macromers can spontaneously cross-link polymers such as poly(N-isopropylacrylamide) to produce rapidly cross-linking, highly swollen, cytocompatible, and hydrolytically degradable hydrogels suitable for mesenchymal stem cell encapsulation. These favorable properties, combined with PdBT's modular design and ease of functionalization, establish strong potential for its usage in tissue engineering applications.

Abstract
We report on an upward traveling, radio-detected cosmic-ray-like impulsive event with characteristics closely matching an extensive air shower. This event, observed in the third flight of the Antarctic Impulsive Transient Antenna (ANITA), a NASA-sponsored long-duration balloon payload, is consistent with a similar event reported in a previous flight. These events could be produced by the atmospheric decay of an upward-propagating τ lepton produced by a ν_{τ} interaction, although their relatively steep arrival angles create tension with the standard model neutrino cross section. Each of the two events have a posteriori background estimates of ≲10^{-2} events. If these are generated by τ-lepton decay, then either the charged-current ν_{τ} cross section is suppressed at EeV energies, or the events arise at moments when the peak flux of a transient neutrino source was much larger than the typical expected cosmogenic background neutrinos.

Abstract
The clinical examination in diagnostic criteria for temporomandibular disorders (DC/TMD) is a strict procedure and comprises mandatory commands. However, learning and using these mandatory commands in general practice have proven to be difficult and their use of DC/TMD is minimal. To investigate whether reliability on a diagnostic level for DC/TMD diagnoses differs between examiners using the mandatory commands or not. Six examiners were divided into two groups: one using the mandatory commands in DC/TMD for the clinical examination and one who did not use the mandatory commands. A reliability assessment was performed twice, one occasion for each group of examiners. The assessment was performed according to the guidelines from the International Network for Orofacial Pain and Related Disorders Methodology. Each group of examiners thereby examined 16 subjects (11 TMD patients and 5 healthy individuals) each, and the diagnostic agreement (reliability) as compared to diagnoses derived by a reference standard examiner was calculated with Cohen' s kappa coefficient. The DC/TMD diagnoses myalgia, arthralgia and headache attributed to TMD were included in the reliability assessment. There was no significant difference regarding diagnostic agreement reliability between the examiners using or not using the mandatory DC/TMD commands. This study indicates that not using the mandatory commands in DC/TMD in general practice does not impair the diagnostic reliability regarding the diagnoses myalgia, arthralgia and headache attributed to TMD compared to including the commands.

Abstract
Amblyopia is a prevalent developmental visual disorder of childhood that typically persists in adults. Due to altered visual experience during critical periods of youth, the structure and function of adult visual cortex is abnormal. In addition to substantial deficits shown with task-based fMRI, previous studies have used resting state measures to demonstrate altered long-range connectivity in amblyopia. This is the first study in amblyopia to analyze connectivity between regions of interest that are smaller than a single cortical area and to apply partial correlation analysis to reduce network effects. We specifically assess short-range connectivity between retinotopically defined regions of interest within the occipital lobe of 8 subjects with amblyopia and 7 subjects with normal vision (aged 19–45). The representations of visual areas V1, V2, and V3 within each of the four quadrants of visual space were further subdivided into three regions based on maps of visual field eccentricity. Connectivity between pairs of all nine regions of interest in each quadrant was tested via correlation and partial correlation for both groups. Only the tests of partial correlation, i.e., correlation between time courses of two regions following the regression of time courses from all other regions, yielded significant differences between resting state functional connectivity in amblyopic and normal subjects. Subjects with amblyopia showed significantly higher partial correlation between para-foveal and more eccentric representations within V1, and this effect associated with poor acuity of the worse eye. In addition, we observed reduced correlation in amblyopic subjects between isoeccentricity regions in V1 and V2, and separately, between such regions in V2 and V3. We conclude that partial correlation-based connectivity is altered in an eccentricity-dependent pattern in visual field maps of amblyopic patients. Moreover, results are consistent with known clinical and psychophysical vision loss. More broadly, this provides evidence that abnormal cortical adaptations to disease may be better isolated with tests of partial correlation connectivity than with the regular correlation techniques that are currently widely used. Cortical functional connectivity abnormalities exist in amblyopia at a scale finer than previously reported. Connectivity changes within primary visual cortex are consistent with known loss of function. Connectivity changes between visual areas are consistent with concept of deafferentation. Partial correlation differentiates patients from controls, whereas correlation does not.
