Abstract
Portal vein embolization (PVE) is a potential tool useful for inducing future liver remnant (FLR) hypertrophy in patients with advanced hepatic malignancies who are at high risk of hepatic insufficiency if treated by surgical resection. However, the safety and effectiveness of PVE in the context of patients who have undergone hepatic arterial infusion (HAI) is unknown. This retrospective, single-center study identified nine patients who underwent PVE after HAI between January 2015 and December 2022. There were no major adverse events, including biliary, or high-grade liver failure. Analysis showed an increase in standardized FLR from 21.1 ± 2.4% to 34.8 ± 2.1% over 9.8 ± 1.2 weeks, with a mean kinetic growth rate of 2.2 ± 0.6%. The study suggested compatibility of PVE after HAI. Patients who have undergone HAI therapy should not be excluded from consideration of PVE as part of their operative clearance strategy.

Abstract
BACKGROUND COVID-19 presented numerous challenges to primary care, but little formal research has explored the experience of practice leaders and their strategies for managing teams as the crisis unfolded. OBJECTIVE Describe the experience of leaders in US primary care delivery organizations, and their strategies for leading teams during COVID-19 and beyond. DESIGN Qualitative study using semi-structured interviews performed between 9/15/2020 and 8/31/2021. PARTICIPANTS Purposive sample of 17 clinical leaders in a range of US primary care organizations. APPROACH An iterative grounded review of interview transcripts was performed, followed by immersion/crystallization analysis. KEY RESULTS Early in the pandemic, practice leaders reported facing rapid change and the need for constant decision-making, amidst an environment of stress, fear, and uncertainty, but this was buffered by a strong sense of purpose. Later, leaders noted the emergence of layered crises, and evolving challenges including fatigue, burnout, and strained relationships within their organizations and with the communities they serve. Leaders described four interrelated strategies for supporting their teams: (1) Being intentionally present, physically and emotionally; (2) Frequent and transparent communication; (3) Deepening and broadening relationships; (4) Increasing adaptive decision-making, alternating between formal hierarchical and flexible participatory processes. These strategies were influenced by individual leaders' perceived autonomy, which was impacted by the leader's specific role, and organizational size, complexity, and funding model. CONCLUSIONS As the burnout and workforce crises have accelerated, the identified strategies can be useful to leaders to support teams and build organizational resilience in primary care moving forward.

Abstract
OBJECTIVE To understand the ways relational organizing practices impacted collaborations between independent or health system-affiliated community health clinics, public health offices, and community groups during the early COVID-19 pandemic. DATA SOURCES AND STUDY SETTING Between November 2020 and June 2021, we interviewed clinical and public health workers, clinic-based community organizers, and staff and volunteers at community organizations who participated in three COVID-19 response collaborations in the Northwestern United States. STUDY DESIGN This was a qualitative study employing participatory and rapid data collection and analysis methods. DATA COLLECTION Research team members invited key participants in organizing efforts to a semi-structured virtual interview conducted by an independent health services researcher. A sensemaking team that included project participants analyzed interview data using an iterative, thematic approach and conducted a ripple effect mapping exercise to supplement interview data. A total of 19 people contributed data for analysis. Analysis was guided by the underlying research questions: whether and how relational organizing practices contributed to successful collaboration, and what challenges were encountered. PRINCIPAL FINDINGS Relational organizing was perceived to contribute to multiple positive project outcomes, including greater self-efficacy in a time of crisis and enhanced sense of connection; these outcomes contributed to a sense of successful collaboration. Four mechanisms were identified that explained relational organizing's collaborative efficacy: (1) mobilizing existing relationships for rapid community engagement; (2) bringing concrete skills for enhancing trust among cross-sector partners; (3) recognizing and addressing power dynamics; and (4) creating vehicles for exercising collective community power. Lack of trust and unsurfaced power dynamics were perceived as common challenges to sustained collaboration, which relational organizing could sometimes mitigate. CONCLUSIONS Our findings suggest relational organizing practices can be protective against common "pain points" faced by cross-sectoral partnerships, especially in times of crisis. Further piloting of clinic-based relational organizing is recommended, as is research on longer-term impacts.

Abstract
In our previous work, we demonstrated that it is feasible to perform analysis on mutation signature data without the need for downloads or installations and analyze individual patient data at scale without compromising privacy. Building on this foundation, we developed an in-browser Software Development Kit (a JavaScript SDK), mSigSDK, to facilitate the orchestration of distributed data processing workflows and graphic visualization of mutational signature analysis results. We strictly adhered to modern web computing standards, particularly the modularization standards set by the ECMAScript ES6 framework (JavaScript modules). Our approach allows for the computation to be entirely performed by secure delegation to the computational resources of the user's own machine (in-browser), without any downloads or installations. The mSigSDK was developed primarily as a companion library to the mSig Portal resource of the National Cancer Institute Division of Cancer Epidemiology and Genetics (NIH/NCI/DCEG), with a focus on FAIR extensibility as components of other researchers' own data science constructs. Anticipated extensions include the programmatic operation of other mutation signature API ecosystems such as SIGNAL and COSMIC, advancing towards a data commons for mutational signature research (Grossman et al., 2016).

Abstract
CdTe-based detectors have the problem of Te-rich surface layers caused by Br etching, which is one of fabrication steps. Te-rich layer acts as a trapping center and serves as an additional source of charge carriers, thereby degrading transport property of charge carriers and enriching leakage current on surface of detector. To solve this problem, we introduced sodium hypochlorite (NaOCl) as a passivant, and investigated its effect on Cd0.95Mn0.05Te0.98Se0.02 (CMTS), by analyzing chemical state of surface and its performance. After passivation with NaOCl, the results of X-ray photoelectron spectroscopy (XPS) shows the formation of tellurium oxide and elimination of water on CMTS surface, and CMTS presented enhanced performance with Am-241 radioisotope. Consequently, it is demonstrated that the passivation with NaOCl reduces leakage current, compensates defect, and elevates transport of charge carriers, thereby decreasing charge loss of carriers and improving performance of CMTS detector.

Abstract
Fluorescence-guided surgery can aid in the intraoperative visualization of target tissues, with promising applications in human and veterinary surgical oncology. The aim of this study was to evaluate the performances of two fluoresce camera systems, IC-FlowTM and VisionsenseTM VS3 Iridum, for the detection of two non-targeted (ICG and IRDye-800) and two targeted fluorophores (AngiostampTM and FAP-Cyan) under different room light conditions, including ambient light, new generation LED, and halogen artificial light sources, which are commonly used in operating theaters. Six dilutions of the fluorophores were imaged in phantom kits using the two camera systems. The limit of detection (LOD) and mean signal-to-background ratio (mSBR) were determined. The highest values of mSBR and a lower LOD were obtained in dark conditions for both systems. Under room lights, the capabilities decreased, but the mSBR remained greater than 3 (=clearly detectable signal). LOD and mSBR worsened under surgical lights for both camera systems, with a greater impact from halogen bulbs on VisionsenseTM VS3 Iridium and of the LED lights on IC-Flow due to a contribution of these lights in the near-infrared spectrum. When considering implementing FGS into the clinical routine, surgeons should cautiously evaluate the spectral contribution of the lights in the operating theater.

Abstract
BACKGROUND High throughput experiments in cancer and other areas of genomic research identify large numbers of sequence variants that need to be evaluated for phenotypic impact. While many tools exist to score the likely impact of single nucleotide polymorphisms (SNPs) based on sequence alone, the three-dimensional structural environment is essential for understanding the biological impact of a nonsynonymous mutation. RESULTS We present a program, 3DVizSNP, that enables the rapid visualization of nonsynonymous missense mutations extracted from a variant caller format file using the web-based iCn3D visualization platform. The program, written in Python, leverages REST APIs and can be run locally without installing any other software or databases, or from a webserver hosted by the National Cancer Institute. It automatically selects the appropriate experimental structure from the Protein Data Bank, if available, or the predicted structure from the AlphaFold database, enabling users to rapidly screen SNPs based on their local structural environment. 3DVizSNP leverages iCn3D annotations and its structural analysis functions to assess changes in structural contacts associated with mutations. CONCLUSIONS This tool enables researchers to efficiently make use of 3D structural information to prioritize mutations for further computational and experimental impact assessment. The program is available as a webserver at https://analysistools.cancer.gov/3dvizsnp or as a standalone python program at https://github.com/CBIIT-CGBB/3DVizSNP .

Abstract
Mass casualty incidents (MCI), particularly involving pediatric patients, are high-risk, low-frequency occurrences that require exceptional emergency arrangements and advanced preparation. In the aftermath of an MCI, it is essential for medical personnel to accurately and promptly triage patients according to their acuity and urgency for care. As first responders bring patients from the field to the hospital, medical personnel are responsible for prompt secondary triage of these patients to appropriately delegate hospital resources. The JumpSTART triage algorithm (a variation of the Simple Triage and Rapid Treatment, or START, triage system) was originally designed for prehospital triage by prehospital providers but can also be used for secondary triage in the emergency department setting. This technical report describes a novel simulation-based curriculum for pediatric emergency medicine residents, fellows, and attendings involving the secondary triage of patients in the aftermath of an MCI in the emergency department. This curriculum highlights the importance of the JumpSTART triage algorithm and how to effectively implement it in the MCI setting.

Abstract
Abstract
Tet-On is a powerful inducible system and a classical tool to regulate gene expression in mammalian cells. It has also been applied to regulate Pol III-driven transcription, such as shRNA or gRNA driven by a U6 or H1 promoter. However, all of the current versions of Tet-On shRNA vectors are based on H1-2O2 or U6-2O2 promoters, which are only compatible with first-generation tetracycline repressor TetR. In addition, these promoters have the problem of driving downstream transcription without the binding of the Tet regulatory protein. Here, we developed a new system that is built upon tetracycline activator protein, Tet-On 3G, combined with a new structure of Tet responsive promoter H1-4O4, which tightly regulates the downstream transcription of gRNA or shRNA. The responsiveness of our system to Doxycycline regulation is dramatically improved compared with the current versions. The new Tet-On system is further optimized into a compact structure to be compatible with the lentivirus package (All-In-One Lenti-Tet-On system), which still keeps the leaky expression at an undetectable level. Combined with all these features, the new generation of the Tet-On system offers broad applications in gene knocking down and genomic editing.

Abstract
The epidermal growth factor receptor (EGFR) signaling pathway is one of the main pathways responsible for propagating the luteinizing hormone (LH) signal throughout the cumulus cells and the oocyte. Recently, we have proposed the C-C motif chemokine receptor 2 (CCR2) and its main ligand (monocyte chemoattractant protein-1, MCP1) as novel mediators of the ovulatory cascade. Our previous results demonstrate that the gonadotropins (GNT), amphiregulin (AREG), and prostaglandin E2 (PGE2) stimulation of periovulatory gene mRNA levels occurs, at least in part, through the CCR2/MCP1 pathway, proposing the CCR2 receptor as a novel mediator of the ovulatory cascade in a feline model. For that purpose, feline cumulus-oocyte complexes (COCs) were cultured in the presence or absence of an EGFR inhibitor, recombinant chemokine MCP1, and gonadotropins [as an inducer of cumulus-oocyte expansion (C-OE), and oocyte maturation] to further assess the mRNA expression of periovulatory key genes, C-OE, oocyte nuclear maturation, and steroid hormone production. We observed that MCP1 was able to revert the inhibition of AREG mRNA expression by an EGFR inhibitor within the feline COC. In accordance, the confocal analysis showed that the GNT-stimulated hyaluronic acid (HA) synthesis, blocked by the EGFR inhibitor, was recovered by the addition of recombinant MCP1 in the C-OE culture media. Also, MCP1 was able to revert the inhibition of progesterone (P4) production by EGFR inhibitor in the C-OE culture media. Regarding oocyte nuclear maturation, recombinant MCP1 could also revert the inhibition triggered by the EGFR inhibitor, leading to a recovery in the percentage of metaphase II (MII)-stage oocytes. In conclusion, our results confirm the chemokine receptor CCR2 as a novel intermediate in the ovulatory cascade and demonstrate that the EGFR/AREG and the CCR2/MCP1 signaling pathways play critical roles in regulating feline C-OE and oocyte nuclear maturation, with CCR2/MCP1 signaling pathway being downstream EGFR/AREG pathway within the ovulatory cascade.

Abstract
Abstract
Proven metallotherapeutics, such as cisplatin and oxaliplatin, alter immune responses as part of their multimodal mechanisms-of-action. These immune responses can drive efficacy in specific patient populations and/or in combination with other oncology drugs. BOLD-100, currently in a multinational Phase 2 trial, is a first-in-class metallotherapeutic that (1) alters the unfolded protein response (UPR) through selective GRP78 inhibition, and (2) induces reactive oxygen species (ROS), leading to DNA damage and cell cycle arrest. Collectively, these pathways result in cell death in both sensitive and resistant cancers, giving BOLD-100 the potential to significantly improve outcomes in a wide range of both solid and liquid tumors in combination with other anticancer therapies. BOLD-100 can also alter immune responses, including through induction of immunogenic cell death, but these responses have not been investigated in a clinical population. A recently completed Phase 1b trial investigating BOLD-100 in combination with FOLFOX demonstrated a 3X improvement in progression-free survival (PFS) in 3rd line or later metastatic colorectal cancer patients compared to existing therapies, with a favorable safety profile. In this Phase 1b study, BOLD-100 was administered via IV infusion for 60-90 minutes immediately prior to FOLFOX on a 2-week cycle. To investigate the pharmacodynamics of immune markers, plasma samples were collected at baseline and 1, 6, 24, and 48 hours after initiation of BOLD-100 plus FOLFOX treatment for each of the first 4 cycles, and then at baseline for all subsequent cycles. In 326 samples collected from 15 patients, 48 cytokines were measured via multiplex. Multiple cytokines showed short-term (1 to 48 hours) transient increases in plasma concentration levels, including IL-10, IL-27, G-CSF, MIP-1β, IP-10, IL-2, IL-18 and TNFα. IL-10, a cytokine previously investigated as an anticancer therapeutic, increased significantly by 1 hour (6.7X increase) and by 6 hours (84.5X increase) after treatment, before reverting to baseline levels by 48 hours. Despite large acute increases in specific cytokines, no changes to baseline levels over multiple treatment cycles were observed. Correlation analysis showed that baseline MCP-1 and MIP-1α levels were negatively correlated with overall survival; and the maximum change in concentration over the first dosage cycle of RANTES, IL-17F, Eotaxin, TGFα and MDC were positively correlated with overall survival. These results show that BOLD-100 in combination with FOLFOX can induce immune responses, and that these immune responses may predict clinical outcome. Analysis of additional patient samples from the Phase 2 trial is ongoing.

Abstract
OBJECTIVES To investigate stifle kinematics and kinetics following TPLO and TPLO combined with an extra-articular lateral augmentation (TPLO-IB) during the tibial compression test (TCT) and the tibial pivot compression test (TPT), applied with an external (eTPT) and an internal moment (iTPT). STUDY DESIGN Experimental ex vivo study. SAMPLE POPULATION Ten cadaveric hindlimbs of dogs weighing 23-40 kg. METHODS 3D-kinematic and kinetic data were collected while performing TCT, eTPT, and iTPT and compared under the conditions (1) normal, (2) CCL deficient, (3) TPLO, and (4) TPLO-IB. Two-way repeated-measures ANOVA was used to examine the effect of test and treatment on kinetic and kinematic data. RESULTS Mean ± SD preoperative TPA was 24.7° ± 1.7°, postoperative TPA was 5.9° ± 0.7°. During TCT, there was no difference in cranial tibial translation between the intact stifle and after TPLO (p = .17). In contrast, cranial tibial translation was six times larger in TPLO compared to intact when performing eTPT and iTPT (p < .001). Cranial tibial translation with TCT, eTPT and iTPT was not different between intact stifle and TPLO-IB. Intraclass correlation coefficient for eTPT and iTPT after TPLO and TPLO-IB was excellent being 0.93 (0.70-0.99) and 0.91 (0.73-0.99), respectively. CONCLUSION Whereas TCT is negative after TPLO, instability persists when a rotational moment is combined using eTPT and iTPT. TPLO-IB neutralizes craniocaudal and rotational instability when performing TCT, eTPT, and iTPT.

Abstract
PURPOSE The purpose of the study's mixed-methods evaluation was to examine the ways in which a relational leadership development intervention enhanced participants' abilities to apply relationship-oriented skills on their teams. DESIGN/METHODOLOGY/APPROACH The authors evaluated five program cohorts from 2018-2021, involving 127 interprofessional participants. The study's convergent mixed-method approach analyzed post-course surveys for descriptive statistics and interpreted six-month post-course interviews using qualitative conventional content analysis. FINDINGS All intervention features were rated as at least moderately impactful by at least 83% of participants. The sense of community, as well as psychological safety and trust created, were rated as impactful features of the course by at least 94% of participants. At six months post-intervention, participants identified benefits of greater self-awareness, deeper understanding of others and increased confidence in supporting others, building relationships and making positive changes on their teams. ORIGINALITY/VALUE Relational leadership interventions may support participant skills for building connections, supporting others and optimizing teamwork. The high rate of skill application at six months post-course suggests that relational leadership development can be effective and sustainable in healthcare. As the COVID-19 pandemic and systemic crises continue to impact the psychological well-being of healthcare colleagues, relational leadership holds promise to address employee burnout, turnover and isolation on interprofessional care teams.

Abstract
Cadmium zinc telluride (CZT) has been actively researched and developed by researchers in various fields. In medical applications, especially photon-counting, CZT enables improved image quality, multi-material decomposition, and improved dose efficiency. Moreover, band gap engineering and selenium addition on CZT improved electrical, spectroscopic and structural properties, thereby supporting performance of CZT as a photon-counting detector. In this study, it is shown that Cd0.875Zn0.125Te0.98Se0.02 (CZTS) shows sufficient performance without loss of detection efficiency. We carried out a study involving the application of this CZTS on calculating bone mineral density (BMD) values, because this application has a novelty of new material for BMD sensor which follows the CdTe- or CdZnTe- based BMD detector. Anatomical images from different energy bins contained different information of attenuation although the images were taken in the same region at the same time. Moreover, calculated BMD values had a proper tendency depending on the amount of bone in that region. The final BMD value was 1.1972 g/cm2, which is close to the real value of 1.2 g/cm2. The introduction with a bone filter and a smaller pixel size will improve the accuracy and precision of photon-counting CZTS detectors for measuring BMD values. However, in this study the CZTS showed the feasibility that a photon-counting CZTS detector can help the measurement of BMD values and the diagnosis of osteoporosis.

Abstract
Introduction Near-infrared (NIR) fluorescence-guided surgery is increasingly utilized in humans and pets. As clinical imaging systems are optimized for Indocyanine green (ICG) detection, the usage of targeted dyes necessitates the validation of these systems for each dye. We investigated the impact of skin pigmentation and tissue overlay on the sensitivity of two NIR cameras (IC-FlowTM, VisionsenseTM VS3 Iridum) for the detection of non-targeted (ICG, IRDye800) and targeted (AngiostampTM, FAP-Cyan) NIR fluorophores in an ex vivo big animal model. Methods We quantitatively measured the limit of detection (LOD) and signal-to-background ratio (SBR) and implemented a semi-quantitative visual score to account for subjective interpretation of images by the surgeon. Results VisionsenseTM VS3 Iridum outperformed IC-FlowTM in terms of LOD and SBR for the detection of all dyes except FAP-Cyan. Median SBR was negatively affected by skin pigmentation and tissue overlay with both camera systems. Level of agreement between quantitative and semi-quantitative visual score and interobserver agreement were better with VisionsenseTM VS3 Iridum. Conclusion The overlay of different tissue types and skin pigmentation may negatively affect the ability of the two tested camera systems to identify nanomolar concentrations of targeted-fluorescent dyes and should be considered when planning surgical applications.

Abstract
ObjectiveThe purpose of this study was to quantify three-dimensional (3D) stifle kinematics during walking in dogs with complete cranial cruciate ligament insufficiency (CCL-I) treated with a CORA-based leveling osteotomy (CBLO).Study designFour client-owned dogs with unilateral complete CCL-I were prospectively enrolled. Custom digital 3D models of the femora and tibiae were created from pre-and postoperative computed tomographic scans for each dog. Lateral view fluoroscopic images were collected during treadmill walking preoperatively and 6 months after CBLO. Results were generated using a 3D-to-2D image registration process. Pre-and postoperative stifle kinematics (craniocaudal translation, extension angle) were compared to that of the unaffected contralateral (control) stifle. Force plate gait analysis was performed, and symmetry indices (SI) were calculated for peak vertical force (PVF) and vertical impulse (VI).ResultsAfter CBLO, craniocaudal femorotibial motion was reduced by a median (range) of 43.0 (17.0–52.6) % over the complete gait cycle. Median (range) PVF SI was 0.49 (0.26–0.56) preoperatively and 0.92 (0.86–1.00) postoperatively, and VI SI was 0.44 (0.20–0.48) preoperatively and 0.92 (0.82–0.99) postoperatively.ConclusionCBLO mitigated but did not fully resolve abnormal craniocaudal translation; lameness was substantially improved at 6 months.

Abstract
BACKGROUND AND PURPOSE Synthetic MR imaging is a time-efficient technique. However, its rather long scan time can be challenging for children. This study aimed to evaluate the clinical feasibility of accelerated synthetic MR imaging with deep learning-based reconstruction in pediatric neuroimaging and to investigate the impact of deep learning-based reconstruction on image quality and quantitative values in synthetic MR imaging. MATERIALS AND METHODS This study included 47 children 2.3-14.7 years of age who underwent both standard and accelerated synthetic MR imaging at 3T. The accelerated synthetic MR imaging was reconstructed using a deep learning pipeline. The image quality, lesion detectability, tissue values, and brain volumetry were compared among accelerated deep learning and accelerated and standard synthetic data sets. RESULTS The use of deep learning-based reconstruction in the accelerated synthetic scans significantly improved image quality for all contrast weightings (P < .001), resulting in image quality comparable with or superior to that of standard scans. There was no significant difference in lesion detectability between the accelerated deep learning and standard scans (P > .05). The tissue values and brain tissue volumes obtained with accelerated deep learning and the other 2 scans showed excellent agreement and a strong linear relationship (all, R 2 > 0.9). The difference in quantitative values of accelerated scans versus accelerated deep learning scans was very small (tissue values, <0.5%; volumetry, -1.46%-0.83%). CONCLUSIONS The use of deep learning-based reconstruction in synthetic MR imaging can reduce scan time by 42% while maintaining image quality and lesion detectability and providing consistent quantitative values. The accelerated deep learning synthetic MR imaging can replace standard synthetic MR imaging in both contrast-weighted and quantitative imaging.

Abstract
A man in his 60s with penetrating ileocolonic Crohn’s disease (CD), recently started on ustekinumab therapy, presented with new onset dyspnoea, paroxysmal nocturnal dyspnoea and dependent oedema. He was diagnosed with heart failure (HF) 10 months after starting ustekinumab therapy. His symptoms resolved with discontinuation of ustekinumab and he had recovery of his cardiac function. Though initial studies that led to the U.S Food and Drug Administration (FDA)approval for ustekinumab did not detect a signal for HF, postmarketing surveillance has detected rare cases of HF after initiation of the medication. This is one of the few reported cases of HF associated with ustekinumab therapy for CD.

Abstract
OBJECTIVE To identify perioperative risk factors for postoperative delirium (POD) in patients aged 65 or older undergoing lumbar spinal fusion procedures. PATIENTS AND METHODS A retrospective cohort analysis was performed on patients undergoing lumbar spinal fusion over an approximately three-year period at a single institution. Demographic and perioperative data were obtained from electronic medical records. The primary outcome was the presence of postoperative delirium assayed by the Delirium Observation Screening Scale (DOSS) and Confusion Assessment Method for the ICU (CAM-ICU). Univariate and multivariate analyses were performed on the data. RESULTS Of the 702 patients included in the study, 173 (24.6%) developed POD. Our analysis revealed that older age (p < 0.001), lower preoperative hemoglobin (p < 0.001), and higher ASA status (p < 0.001), were significant preoperative risk factors for developing POD. The only significant intraoperative risk factor was a higher number of spinal levels that were instrumented (p < 0.001). Higher pain scores on postoperative day 1 (p < 0.001), and lower postoperative hemoglobin (p < 0.001) were associated with increased POD; as were ICU admission (p < 0.001) and increased length of ICU stay (p < 0.001). Patients who developed POD had a longer hospital stay (p < 0.001) with lower rates of discharge to home as opposed to an inpatient facility (p < 0.001). CONCLUSION Risk factors for POD in older adults undergoing lumbar spinal fusion surgery include advanced age, diabetes, lower preoperative and postoperative hemoglobin, higher ASA grade, greater extent of surgery, and higher postoperative pain scores. Patients with delirium had a higher incidence of postoperative ICU admission, increased length of stay, decreased likelihood of discharge to home and increased mortality, all consistent with prior studies. Further studies may determine whether adequate management of anemia and pain lead to a reduction in the incidence of postoperative delirium in these patients.

Abstract
MOTIVATION The Division of Cancer Epidemiology and Genetics (DCEG) and the Division of Cancer Prevention (DCP) at the National Cancer Institute (NCI) have recently generated genome-wide association study (GWAS) data for multiple traits in the Prostate, Lung, Colorectal, and Ovarian (PLCO) Genomic Atlas project. The GWAS included 110 000 participants. The dissemination of the genetic association data through a data portal called GWAS Explorer, in a manner that addresses the modern expectations of FAIR reusability by data scientists and engineers, is the main motivation for the development of the open-source JavaScript software development kit (SDK) reported here. RESULTS The PLCO GWAS Explorer resource relies on a public stateless HTTP application programming interface (API) deployed as the sole backend service for both the landing page's web application and third-party analytical workflows. The core PLCOjs SDK is mapped to each of the API methods, and also to each of the reference graphic visualizations in the GWAS Explorer. A few additional visualization methods extend it. As is the norm with web SDKs, no download or installation is needed and modularization supports targeted code injection for web applications, reactive notebooks (Observable) and node-based web services.

Abstract
Abstract
Cell line screening of unique compounds can provide mechanistic insights and identify optimal drug combination partners. Bioinformatics analysis of cell screen data and correlation to publicly available datasets can support identification of appropriate patient populations for subsequent preclinical and clinical development. BOLD-100 is a first-in-class ruthenium-based anticancer agent currently being tested in a Phase 1b/2a clinical trial in combination with FOLFOX in the treatment of advanced gastrointestinal cancers. BOLD-100 works by altering the unfolded protein response through selective GRP78 inhibition; and inducing reactive oxygen species which causes DNA damage and cell cycle arrest. Collectively, these result in cell death in a range of different cancer types, and in combination with many different classes of anticancer agents. To determine optimal indications for BOLD-100 development, BOLD-100 was tested against 316 cancer cell lines in 72-hour Cell Titer Glo assays with downstream bioinformatic analysis and validation experiments. Multiple cancer types showed preferential response to BOLD-100, including bladder, esophageal, pancreatic, multiple myeloma and ovarian cancers. Subtype analysis identified potential populations of increased responsiveness, including in bladder cancer where BOLD-100 had increased response in luminal and mixed subtypes, as compared to basal subtypes. Utilizing bladder cancer as a case study, subsequent combination testing of BOLD-100 in combination with fluorouracil or cisplatin demonstrated that BOLD-100 enhanced cell death across different bladder cancer cell lines through synergistic interactions with these standard-of-care agents. The pan-cancer response profile of BOLD-100 was compared against 449 other anticancer drug responses that are part of the GDSC database. BOLD-100 displayed limited correlation with existing drugs, suggesting a unique mechanism of action and clinical utility where standard-of-care agents have limited efficacy. Pharmacogenomic analysis of the cell screen data indicated potential pathways and genes of relevance to BOLD-100 response, including increased response in KRAS-mutant cancers. Collectively, BOLD-100 showed a unique sensitivity profile across a panel of over 300 cancer cell lines, identifying multiple potential indications for future development. Subsequent investigations into several cancer types of interest and drug combinations are ongoing.

Abstract
Research to date offers inconclusive and even conflicting evidence regarding whether organizations learn from failure. The present study sheds new light on this debate by highlighting a previously overlooked factor: whether the failure was caused by human error. In attempts to learn from failure, organizational members tend to focus on simplified representations of experiences and, in doing so, distinguish between failures attributed to human errors versus other causes. Our core thesis is that failures resulting from human error attract significant amounts of attentional resources, thereby depleting the limited stock of organizational attention otherwise directed at managing the risk of failures resulting from other causes. We hypothesize that this disproportionate allocation of attention simultaneously is associated with both positive learning outcomes and negative side effects, specifically, a subsequent decrease in failures resulting from human error and also an increase in failures resulting from other causes. We also hypothesize that failures resulting from causes other than human error attract less organizational attention and, thus, lead to weaker learning outcomes. The proposed hypotheses were tested and supported using data from accident reports filed by natural gas pipeline operators with the U.S. Pipeline Hazardous Materials Safety Administration from 2002 to 2012. Additional analyses, including text analysis of accident reports, a series of simulations, and a supplementary study, point to organizational attention as the mechanism at play. Taken together, these findings suggest that organizational learning from failure caused by human error produces not only benefits, but also unintended consequences.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) is one of the most common chronic inflammatory diseases and is characterized by sinonasal inflammation that lasts longer than 12 weeks. Whether the effect of chronic inflammation caused by CRS on cardiovascular diseases (CVDs) is similar to its effect on other inflammatory disorders has not been thoroughly evaluated. We aimed to demonstrate whether CRS patients have a higher prevalence of CVDs, including stroke and ischemic heart disease (IHD). METHODOLOGY We compared the prevalence of various comorbidities between CRS and control participants through a case-control cohort study from 2002 to 2015 that included 514,866 participants. CRS (n=6,552) and control (n=26,208) participants who were over 40 years old were selected by matching age, sex, income, and area of residence at a 1:4 ratio. RESULTS A stratified Cox proportional hazards model was utilized to assess the hazard ratio (HR) of CRS for stroke and IHD. The HRs for stroke and IHD were significantly increased in CRS patients compared to controls after adjusting for obesity, alcohol consumption, smoking, systolic and diastolic blood pressure, fasting blood glucose, total cholesterol, hemoglobin, and Charlson Comorbidity Index (CCI) scores. The HR of stroke was significantly higher in the absence of nasal polyps than in the presence of nasal polyps. The HR of IHD was significantly increased in the CRS group regardless of the presence of nasal polyps. CONCLUSIONS This study showed that CRS participants had a significantly higher prevalence of stroke and IHD.

Abstract
Consortium-based research is crucial for producing reliable, high-quality findings, but existing tools for consortium studies have important drawbacks with respect to data protection, ease of deployment, and analytical rigor. To address these concerns, we developed COnsortium of METabolomics Studies (COMETS) Analytics to support and streamline consortium-based analyses of metabolomics and other -omics data. The application requires no specialized expertise and can be run locally to guarantee data protection or through a Web-based server for convenience and speed. Unlike other Web-based tools, COMETS Analytics enables standardized analyses to be run across all cohorts, using an algorithmic, reproducible approach to diagnose, document, and fix model issues. This eliminates the time-consuming and potentially error-prone step of manually customizing models by cohort, helping to accelerate consortium-based projects and enhancing analytical reproducibility. We demonstrated that the application scales well by performing 2 data analyses in 45 cohort studies that together comprised measurements of 4,647 metabolites in up to 134,742 participants. COMETS Analytics performed well in this test, as judged by the minimal errors that analysts had in preparing data inputs and the successful execution of all models attempted. As metabolomics gathers momentum among biomedical and epidemiologic researchers, COMETS Analytics may be a useful tool for facilitating large-scale consortium-based research.

Abstract
STUDY DESIGN Retrospective cohort study OBJECTIVE: The aim of this study was to investigate the effect of body mass index (BMI) on the reoperation rate and cervical sagittal alignment of patients who underwent posterior cervical decompression and fusion for cervical spondylotic myelopathy (CSM). SUMMARY OF BACKGROUND DATA Cervical sagittal balance has been correlated with postoperative clinical outcomes. Previous studies have shown worse postoperative sagittal alignment and higher reoperation rates in patients with high BMI undergoing anterior decompression and fusion. Similar evidence for the impact of obesity in postoperative sagittal alignment for patients with (CSM) undergoing posterior cervical decompression and fusion (PCF) is lacking. METHODS A retrospective analysis of 198 patients who underwent PCF for cervical myelopathy due to degenerative spine disease was performed. Demographics, need for reoperation, and perioperative radiographic parameters were collected. Cervical lordosis (CL), C2-7 sagittal vertical axis (SVA), and T1 slope (T1S) was measured on standing lateral radiographs. Comparative analysis of the patient cohort was performed by stratifying the sample population into three BMI categories (<25, 25-30, ≥30). RESULT Of the 198 patients that met inclusion criteria, 53 had BMI normal (<25), 65 were overweight (25-30), and 80 were obese (≥30). Mean SVA increased postoperatively in all groups, 4 mm in the normal group, 13 mm in the overweight group, and 13 mm in the obese group (p = 0.003). There was no significant difference in the postoperative change of cervical lordosis or T1 slope between the groups. Multivariate analysis demonstrated fusions involving the cervicothoracic junction and those involving 5 or more levels significantly affected alignment parameters. There were 27 complications requiring reoperation (14%) with no significant differences among the groups stratified by BMI (p = 0.386). CONCLUSIONS Overweight patients (BMI>25) with CSM undergoing PCF had a greater increase in SVA than normal weight patients while reoperation rates were similar. In addition, preoperative CL increased with increasing BMI, although this trend was not Powered by Editorial Manager® and ProduXion Manager® from Aries Systems Corporation significant and there was not found to be a significant difference between the change in CL from baseline to post-fusion between BMI cohorts. This study further highlights the importance of considering BMI when attempting to optimize sagittal alignment in patients undergoing PCF.

Abstract
OBJECTIVE To evaluate intradiskal pressure (IDP) in the C6-7 intervertebral disk (IVD) after destabilization and distraction-fusion of the C5-C6 vertebrae. SAMPLE 7 cadaveric C4-T1 vertebral specimens with no evidence of IVD disease from large-breed dogs. PROCEDURES Specimens were mounted in a custom-made 6 degrees of freedom spinal loading simulator so the C5-C6 and C6-C7 segments remained mobile. One specimen remained untreated and was used to assess the repeatability of the IDP measurement protocol. Six specimens underwent 3 sequential configurations (untreated, partial diskectomy of the C5-6 IVD, and distraction-fusion of the C5-C6 vertebrae). Each construct was biomechanically tested under neutral, flexion, extension, and right-lateral bending loads. The IDP was measured with a pressure transducer inserted into the C6-7 IVD and compared between the nucleus pulposus and annulus fibrosus and across all 3 constructs and 4 loads. RESULTS Compared with untreated constructs, partial diskectomy and distraction-fusion of C5-C6 decreased the mean ± SD IDP in the C6-7 IVD by 1.3 ± 1.3% and 0.8 ± 1.3%, respectively. During motion, the IDP remained fairly constant in the annulus fibrosus and increased by 3.8 ± 3.0% in the nucleus pulposus. The increase in IDP within the nucleus pulposus was numerically greatest during flexion but did not differ significantly among loading conditions. CONCLUSIONS AND CLINICAL RELEVANCE Distraction-fusion of C5-C6 did not significantly alter the IDP of healthy C6-7 IVDs. Effects of vertebral distraction-fusion on the IDP of adjacent IVDs with degenerative changes, such as those in dogs with caudal cervical spondylomyelopathy, warrant investigation.

Abstract
BACKGROUND Inconsistent results about the effect of air pollution on chronic rhinosinusitis (CRS) have been reported. This study aimed to evaluate the impact of meteorological conditions/air pollution on the prevalence of CRS in adult Koreans. METHODOLOGY The data from the Korean National Health Insurance Service-Health Screening Cohort from 2002 through 2015 were used. A CRS group (defined as ICD-10 codes J32, n=6159) was matched with a control group (n=24,636) in 1:4 ratios by age, sex, income, and region of residence. The meteorological conditions and air pollution data included the daily mean, highest, and lowest temperature (°C), daily temperature range (°C), relative humidity (%), ambient atmospheric pressure (hPa), sunshine duration (hr), and the rainfall (mm), SO2 (ppm), NO2 (ppm), O3 (ppm), CO (ppm), and PM10 (μg/m3) levels before the CRS diagnosis. Crude and adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for CRS were analyzed using logistic regression analyses. RESULTS When the NO2 level increased by 0.1 ppm, the odds for CRS increased 5.40 times, and when the CO level increased by 1 ppm and PM10 increased by 10 μg/m3, the odds for CRS decreased 0.75 times and 0.93 times, respectively. Other meteorological conditions, such as the mean/highest/lowest temperature, temperature range, rainfall and other air pollution, such as SO2 and O3, were not statistically significant. NO2 for 90 days before the index date increased the risk of CRS in all subgroups, except for the nasal polyp and older age subgroups. CONCLUSION CRS is related to high concentrations of NO2.

Abstract
To compare the diagnosis andtreatment rates of osteoporosis and diabetes in Korea, a nationwide database was used. The results showed that although osteoporosis management is improving, it is still lower compared with that of diabetes; thus, further efforts are needed in this regard. INTRODUCTION This study aimed to re-evaluate the diagnosis and treatment of osteoporosis from the KNHANES 2016-2017 and compare the temporal change of the rate with those of diabetes as another prevalent chronic disease in South Korea. METHODS The prevalence of osteoporosis in 2016 was estimated using the previous data classified by age groups (50-59,60-69, and ≥70years) and the 2016 Korean census data. The physician diagnosis and treatment rates of osteoporosis in adults aged ≥50years were estimated using the 2016-2017 KNHANES data. The physician diagnosis and treatment rates of diabetes were evaluated using the KNHANES 2008-2009 and 2016-2017 data. RESULTS The estimated physician diagnosisrate of osteoporosis increased from 29.9% in females and 5.8% in males in 2008-2009 to 62.8% in females and 22.8% in males in 2016-2017. The treatment rate for the estimated total number of patients with osteoporosis increased from 14.4% in females and 3.8% in males in 2008-2009 to 32.2% in females and 9.0% in males in 2016-2017. An increasing trend in the estimated treatment rateof physician-diagnosed osteoporosis patients was not observed (48.3% [2008-2009] vs 51.5% [2016-2017] in females; 42.6% [2008-2009] vs 42.2% [2016-2017] in males). The physician diagnosis and treatment rates of diabetes were considerably better and more stable than those of osteoporosis. CONCLUSION Osteoporosis management in South Korea is improving but is insufficient compared with diabetes management. More extensive efforts are needed to improve the diagnosis and treatment rates of osteoporosis.

Abstract
BACKGROUND Chronic rhinosinusitis (CRS) and chronic otitis media (COM) share pathophysiological mechanisms such as bacterial infection, biofilm, and persistence of the obstruction state of ventilation routes. However, only a few studies have investigated the relationship between these two diseases nationwide and in the general population. The purpose of this study was to determine whether the incidence of COM in patients with CRS differed from that of a matched control from the national health screening cohort. METHODS Data from the Korean Health Insurance Review and Assessment Service-National Patient Samples were collected from 2002 to 2015. Participants who were treated ≥ ≥ ≥2 times and underwent head and neck computed tomography evaluation were selected. A 1:4 matched CRS group (n=8,057) and a control group (n=32,228) were selected. The control group included participants who were never treated with the ICD-10 code J32 from 2002 to 2015. The CRS group included CRS patients with/without nasal polyps. RESULTS The incidence of COM was significantly higher in the CRS group than in the control group. In a subgroup analysis, the incidence of COM in all age groups and in men and women was significantly higher in the CRS group than in the control group. More, CRS increased the risk of COM. CONCLUSIONS A significant association was observed between CRS and COM. This indicates that CRS patients have a high risk of developing COM.

Abstract
BACKGROUND: Cardiovascular disease is one of the main causes of mortality in patients with chronic obstructive pulmonary disease (COPD), and atherosclerosis is a cause of cardiac comorbidities in COPD. However, it is not clear whether airflow limitation is associated with atherosclerosis irrespective of smoking.OBJECTIVE: To investigate whether airflow limitation is independently associated with vascular stiffness.METHODS: We enrolled 18 893 participants (male 70.5%; mean age 47.5 ± 9.8 years; never smokers 44.2%) who underwent spirometry and brachial-ankle pulse wave velocity (baPWV) as part of a standard health examination at Ajou University Hospital, Suwon, South Korea, from January 2010 to December 2015.We defined vascular peripheral atherosclerosis as baPWV ≥ 1400 cm/s and airflow limitation as pre-bronchodilator ratio of forced expiratory volume in 1 sec (FEV1) to forced vital capacity (FVC) <70%.RESULTS: Mean baPWV was higher in subjects with airflow limitation (1477.6 ± 331.7 cm/sec, n = 638) than in those without airflow limitation (1344.1 ± 231.8 cm/sec, n = 18255, P < 0.001). In multivariate logistic regression analysis, the following were independent predictors associated with peripheral atherosclerosis (P < 0.05): age, male sex, fasting serum glucose, mean blood pressure, serum leukocyte count, serum low density lipoprotein level and FEV1.CONCLUSION: Airflow limitation was an independent predictor of vascular stiffness irrespective of smoking history, which suggests that airflow limitation is linked with atherosclerosis.

Abstract
PREMISE The Ocotea complex contains the greatest diversity of Lauraceae in the Neotropics. However, the traditional taxonomy of the group has relied on only three main floral characters, and previous molecular analyses have used only a few markers and provided limited support for relationships among the major clades. This lack of useful data has hindered the development of a comprehensive classification, as well as studies of character evolution. METHODS We used RAD-seq data to infer the phylogenetic relationships of 149 species in the Ocotea complex, generating a reference-based assembly using the Persea americana genome. The results provide the basis for a phylogenetic classification that reflects our current molecular knowledge and for analyses of the evolution of breeding system, stamen number, and number of anther locules. RESULTS We recovered a well-supported tree that demonstrates the paraphyly of Licaria, Aniba, and Ocotea and clarifies the relationships of Umbellularia, Phyllostemonodaphne, and the Old World species. To begin the development of a new classification and to facilitate precise communication, we also provide phylogenetic definitions for seven major clades. Our ancestral reconstructions show multiple origins for the three floral characters that have routinely been used in Lauraceae systematics, suggesting that these be used with caution in the future. CONCLUSIONS This study advances our understanding of phylogenetic relationships and character evolution in a taxonomically difficult group using RAD-seq data. Our new phylogenetic names will facilitate unambiguous communication as studies of the Ocotea complex progress.

Abstract
The US health care system has a long history of discouraging the creation
and maintenance of meaningful relationships between patients and
providers. Fee-for-service payment models, the 1-directional,
paternalistic approach of care providers, electronic health records,
anddocumentation requirements, all present barriers to the development
of meaningful relationships in clinic visits. As patients and
providers adopt and experiment with telemedicine and other systems
changes to accommodate the impact of Coronavirus disease 2019, there
is an opportunity to reimagine visits entirely—both office-based and
virtual—and leverage technology to transform a unidirectional model
into one that values relationships as critical facilitators of health
and well-being for both patients and providers.

Abstract
Abstract
Although next generation sequencing (NGS) has become commonplace for breast and other cancers, interpretation of reports remains a challenging unmet need. This is further confounded by the therapeutic importance of understanding and interpreting whether pathogenic variants/mutations are germline versus somatic. Here we will discuss and provide examples of how molecular tumor boards can aid clinicians in providing interpretation of NGS results for optimal patient benefit.

Abstract
BACKGROUND The Breslow depth is an important parameter to determine the excision margin and prognosis of melanoma. However, it is difficult to accurately determine the actual Breslow depth before surgery using the existing ocular micrometer and biopsy technique. OBJECTIVES To evaluate the use of 3D wide-field multispectral photoacoustic imaging to non-invasively measure depth and outline the boundary of melanomas for optimal surgical margin selection. METHODS Six melanoma patients were examined in vivo using the 3D multispectral photoacoustic imaging system. For five cases of melanomas (one in situ, three nodular, and one acral lentiginous type melanoma), the spectrally unmixed photoacoustic depths were calculated and compared against histopathological depths. RESULTS Spectrally unmixed photoacoustic depths and histopathological depths match well within a mean absolute error of 0.36 mm. In particular, the measured minimum and maximum depths in the in situ and nodular type of melanoma were 0.6 and 9.1 mm, respectively. In the 3D photoacoustic image of one metastatic melanoma, feeding vessels were visualized in the melanoma, suggesting the neovascularization around the tumour. CONCLUSIONS The 3D multispectral photoacoustic imaging not only provides well-measured depth and sizes of various types of melanomas, it also visualizes the metastatic type of melanoma. Obtaining accurate depth and boundary information of melanoma before surgery would play a useful role in the complete excision of melanoma during surgery.

Abstract
UNLABELLED The risks for hip fracture and vertebral fracture, but not the risk for distal radius fracture, were significantly higher in the blindness group than in the control group with a maximum 12-year follow-up. PURPOSE To evaluate the influence of visual impairment on the risk for osteoporotic fractures at common sites: hip, thoracic/lumbar vertebra, and distal radius. METHODS This longitudinal follow-up study used a database of a national sample cohort from 2002 to 2013 provided by the Korean National Health Insurance Service. Of a total of 1,125,691 subjects, 3918 patients with visual impairment and age ≥ 50 years were enrolled in a 1:4 ratio; 15,672 control participants were matched for age, sex, income, and region of residence. Stratified Cox proportional-hazards models were used to evaluate the crude and adjusted (for steroid medication, rheumatoid arthritis, depression, osteoporosis, diabetes mellitus, and stroke history) hazard ratios (HRs) for each fracture site. Fracture diagnoses were based on the ICD-10 codes: hip fracture (S720, S721, S722), vertebral fracture (S220, S320), and distal radius fracture (S525). RESULTS The HRs for hip and vertebral fracture were significantly higher in the blindness group (adjusted HR = 2.46, p < 0.001 for hip fracture; adjusted HR = 1.42, p = 0.020 for thoracic/lumbar vertebral fracture) than in the matched control group. However, the HR for distal radius fracture was not higher in the blindness group. The HRs for all three fracture sites were not significantly higher in the non-blindness visual impairment group after adjustment. CONCLUSION The risks for hip fracture and vertebral fracture were significantly higher in the blindness group. However, the risk for distal radius fracture was not related to visual impairment including blindness.

Abstract
Background Anemia is common in cardiac surgery affecting 25-40% of patients and associated with increased blood transfusions, morbidity, mortality, and higher hospital costs. Higher rates of stroke, acute renal injury, and total number of adverse postoperative outcomes have also been reported to be associated with preoperative anemia. This systematic review assessed the current evidence for preoperative intravenous iron on major outcomes following cardiac surgery. Methods Outcome measures included postoperative hemoglobin, transfusion rates, major adverse events, and mortality. The review was conducted according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines, and articles were identified using PubMed, Cochrane, CLINAHL, WOS, and EMBASE databases. Articles were included if they compared patients with and without preoperative anemia based on treatment with intravenous iron. Quality was assessed using Cochrane Risk of Bias Tool and Newcastle-Ottawa scale, and strength of evidence was assessed using the Grading of Recommendations, Assessment, Development and Evaluations (GRADE) approach. Results Of the articles reviewed, six met inclusion criteria. These included four randomized double-blind prospective cohort studies, one randomized non-blinded prospective study, and one non-randomized non-blinded prospective study with historical control. Across studies, 1,038 patients were enrolled. Two studies showed higher hemoglobin with iron therapy, and only one study showed significant differences in multiple outcomes such as transfusion and morbidity. Conclusions Given the paucity of studies and biases within them, the current evidence for treatment with intravenous iron prior to cardiac surgery is weak. More evidence is needed to support the administration of preoperative intravenous iron in cardiac surgery patients.
