Abstract
Background/Objective. Enlarged lateral ventricle (LV) volume and decreased volume in the corpus callosum (CC) are hallmarks of schizophrenia (SZ). We previously showed an inverse correlation between LV and CC volumes in SZ, with global functioning decreasing with increased LV volume. This study investigates the relationship between LV volume, CC abnormalities, and the microRNA MIR137 and its regulated genes in SZ, because of MIR137's essential role in neurodevelopment. Methods. Participants were 1224 SZ probands and 1466 unaffected controls from the GENUS Consortium. Brain MRI scans, genotype, and clinical data were harmonized across cohorts and employed in the analyses. Results. Increased LV volumes and decreased CC central, mid-anterior, and mid-posterior volumes were observed in SZ probands. The MIR137-regulated ephrin pathway was significantly associated with CC:LV ratio, explaining a significant proportion (3.42 %) of CC:LV variance, and more than for LV and CC separately. Other pathways explained variance in either CC or LV, but not both. CC:LV ratio was also positively correlated with Global Assessment of Functioning, supporting previous subsample findings. SNP-based heritability estimates were higher for CC central:LV ratio (0.79) compared to CC or LV separately. Discussion. Our results indicate that the CC:LV ratio is highly heritable, influenced in part by variation in the MIR137-regulated ephrin pathway. Findings suggest that the CC:LV ratio may be a risk indicator in SZ that correlates with global functioning.

Abstract
OBJECTIVE To assess if the dental follicle volume of palatally impacted canines (PICs) affects the relative root position of the adjacent lateral incisors (LIs) and first premolars (FPs). MATERIALS AND METHODS A retrospective cross-sectional study of 49 patients with unilaterally PICs with dental follicles who had CBCT imaging previously taken. Four orthodontic centers in different countries provided the sample. A mean difference of 5° between the angular measurements (mesiodistal tip, buccolingual inclination, or mesiodistal rotation) of the LI and FP adjacent to the PIC and the controls was considered clinically relevant. A value of 0.05 was set for significance level and a power of 80%. The minimum sample size was determined to be 26 patients. These patients were further assigned to an LI sample (n = 49) and an FP sample (n = 23), dependent on the direct contact of the dental follicle to that adjacent tooth. A manual segmentation technique was used to obtain the volumetric measurements of the dental follicle. Angular measurements of adjacent teeth were then compared to the contralateral nonimpacted side, which acted as the control. A multivariant regression analysis was performed using IBM SPSS software, and statistical significance was set at α = 0.05. RESULTS Adequate intra-rater reliability was accomplished. The multivariant regression analysis implied that there is no difference in the mean change in the tip, torque, and rotation of the LI and FP between the impacted and control sides when dental follicle volumes are considered (P = .509 for the LI sample and P = .804 for the FP sample). LIMITATIONS CBCT imaging of dental follicle border delimitations, partial volume effect, and scattering are limitations. This is a convenience sample where the FP subsample is small. CONCLUSION The dental follicle volume of the PICs does not seem to influence the relative position of the adjacent LI and FP mesiodistal tip, buccolingual inclination, and mesiodistal rotation. Early intervention could have been suggested to avoid certain malocclusion traits if significant displacements were demonstrated.

Abstract
BACKGROUND Using high awake blood pressure (BP; ≥130/80 mm Hg) on ambulatory BP monitoring (ABPM) as a reference, the purpose of this study was to determine the accuracy of high office BP (≥130/80 mm Hg) at an initial visit and high confirmatory office BP (≥130/80 mm Hg), and separately, high home BP (≥130/80 mm Hg) among participants with high office BP (≥130/80 mm Hg) at an initial office visit. METHODS AND RESULTS The accuracy of office BP measurements using the oscillometric method for detecting high BP on ABPM was determined among 379 participants with complete office BP and ABPM data in the IDH (Improving the Detection of Hypertension) study. For detecting high BP on ABPM, the accuracy of high confirmatory office BP using the oscillometric method and, separately, high home BP was also determined among the subgroup of 122 participants with high office BP at an initial visit and complete home BP monitoring data. High office BP had moderate sensitivity (0.61 [95% CI, 0.53-0.68]) and high specificity (0.85 [95% CI, 0.80-0.90]) for high awake BP. High confirmatory office BP and high home BP had moderate sensitivity (0.69 [95% CI, 0.59-0.79] and 0.79 [95% CI, 0.71-0.87], respectively) and low and moderate specificity (0.44 [95% CI, 0.27-0.61] and 0.72 [95% CI, 0.56-0.88], respectively). CONCLUSIONS Many individuals with high BP on ABPM do not have high office BP. Confirmatory office BP and home blood pressure monitoring also had limited ability to identify individuals with high BP on ABPM.

Abstract
BACKGROUND Home blood pressure (BP) monitoring over a 7-day period is recommended to confirm the diagnosis of hypertension. METHODS We determined upper and lower home BP thresholds with >90% positive predictive value and >90% negative predictive value using 1 to 6 days of monitoring to identify high home BP (systolic BP ≥130 mm Hg or diastolic BP ≥80 mm Hg) based on 7 days of home BP monitoring. The sample included 361 adults from the Improving the Detection of Hypertension Study who were not taking antihypertensive medication. We used two 7-day periods, at least 3 days apart, the first being a sampling period and the second a reference period. For each number of days in the sampling period, we determined the percentage of participants who had a high likelihood of having (>90% positive predictive value) or not having (>90% negative predictive value) high BP and would not need to continue home BP monitoring. Only the participants in an uncertain category (ie, positive predictive value ≤90% and negative predictive value ≤90%) after each day were carried forward to the next day of home BP monitoring. RESULTS Of the 361 participants (mean [SD] age of 41.3 [13.2] years; 60.4% women), 38.0% had high home BP during the reference period. There were 63.7%, 17.1%, 10.5%, 3.3%, 3.6%, and 1.4% participants who would not need to continue after 1, 2, 3, 4, 5, and 6 days of monitoring. CONCLUSIONS In most people, high home BP can be identified or excluded with a high degree of confidence with 3 days or less of monitoring.

Abstract
PURPOSE/OBJECTIVE(S) There has been increased interest in the use of short course hypofractionated radiotherapy as part of a total neoadjuvant treatment (TNT) approach in the management of rectal cancer since publication of the RAPIDO trial. However, the literature on short course radiation for rectal cancer has not reported significant acute toxicities in the weeks immediately following the completion of treatment. Anecdotally, a subset of patients has experienced acute neuropathic pain characterized in a lumbosacral distribution. This study investigates acute lumbosacral toxicity for patients receiving hypofractionated short course radiation as part of their definitive treatment for rectal cancer. MATERIALS/METHODS We retrospectively analyzed 75 patients with locally advanced rectal adenocarcinoma treated with hypofractionated short course radiation (25 Gy in 5 fractions) at our institution between 2016 and 2022. Acute toxicity caused by radiation was defined as that occurring from the start of radiation treatment to either 30 days post radiation completion, the start of chemotherapy, or date of surgery, whichever occurred first. RESULTS Among 75 patients treated with hypofractionated short course preoperative radiation with definitive intent, we identified 10 patients (13.3%) who experienced significant lumbosacral neuropathic pain and initiated a report to their medical providers during the acute toxicity time frame. Commonly, this was described as an achy pain in the bilateral buttocks radiating down to the knees or posterior claves. Patients rated this pain between moderate to extreme and management included steroids after failure of improvement with conservative measures, gabapentin, and conservative treatment with NSAIDs and Tylenol. Average time to onset of acute lumbosacral neuropathic pain was 3.7 days (SD 2.05) from start of RT. CONCLUSION We have identified a previously underappreciated acute toxicity of neuropathic lumbosacral pain in short course hypofractionated radiation therapy, which may be due to a lumbosacral plexus toxicity. Further analysis will seek to identify predictive factors such as comorbidities and dose to the lumbosacral plexus, and to determine whether there is a correlation between these observed acute toxicities and long-term outcomes.

Abstract
Importance Oral chemotherapy is often dispensed to patients as a 1-month supply, with pill dose and package size predetermined by the drug manufacturer; thus, changing the patient dosage may waste the remaining initial drug supply. The cost of pills wasted due to dose modification and discontinuation is often unreported. Objective To estimate the cost of pill wastage due to dose modification and discontinuation for oral anticancer drugs that were recently approved by the US Food and Drug Administration (FDA) or that are commonly prescribed. Design, Setting, and Participants This retrospective cross-sectional economic evaluation initially identified 26 oral anticancer drugs newly approved between January 1, 2020, and August 31, 2022, from the FDA website and the top 50 best-selling pharmaceuticals in 2021 abstracted from the Drug Discovery Trends website managed by Drug Discovery and Development. The monthly costs of each agent were extracted from the Micromedex RED BOOK database. The FDA package insert, and in some cases PubMed, of each identified drug and indication was searched (matching on trial registration number) for information on registration trials. Information extracted for each drug included the name of the drug approved, drug target, cost of the drug, number of pills per bottle, available strengths, indication, name of the trial, number of patients exposed to treatment drug, number of dose level reductions, median duration of treatment, percentage of patients who received dose reduction, and percentage of dose discontinuation. All variables included in calculations were derived from the package insert or original trial publication. Main Outcomes and Measures The cost of wastage for selected oral anticancer drugs due to dose reduction or discontinuation and the percentage of wastage in comparison with the total cost of treatment. Results After removing duplicates, 22 oral anticancer medications were included in the study. Because some drugs had more than 1 indication, data from 35 clinical trials were analyzed. Eight of the medications (covering 9 indications) had pill strengths divisible at each dose-reduction level; thus the cost of reduction for these pills was assumed to be zero. Two medications did not allow for dose reduction. The median cost of wastage from dose reduction and discontinuation was $1750 (range, $43-$27 200), with a mean cost of $4290 (SD, $5720) per patient. The median percentage of wastage from the total cost of treatment was 1.04% (range, 0.04%-10.80%) with a mean of 1.78% (SD, 2.21%). Conclusions and Relevance This economic evaluation found that due to both the high cost per pill and limited pill strength availability, the mean cost of wastage associated with dose reduction or discontinuation was $4290 per patient. These results suggest that to reduce the financial burden for patients with cancer, regulatory bodies should enforce availability of pill strengths that will limit pill wastage during dose modification or recommend that drug manufacturers issue credit for unused pills.

Abstract
AlGaN-based UV-A LEDs have wide applications in medical treatment and chemical sensing; however, their efficiencies are still far behind visible LEDs or even shorter wavelengths UV-C counterparts because of the large lattice mismatch between the low-Al-content active region and the AlN substrate. In this report, we investigated the composition and thickness of the quantum barrier in the active region in terms of LED performance. Due to the improved strain management and better carrier confinement, efficient UV-A LEDs (320 nm - 330 nm) with EQEs up to 6.8% were demonstrated, among the highest efficiencies at this wavelength range.

Abstract
INTRODUCTION Community treatment orders (CTOs) enable patients to actively engage in mental health services while being supervised in the community outside the hospital setting. However, the efficacy of CTOs remains controversial in terms of mental health services usage or service contacts, emergency visits, and violence. METHODS The databases PsychINFO, Embase, and Medline were searched on 11 March 2022 by 2 independent reviewers through the Covidence website (www.covidence.org). Randomised or non-randomised case-control studies and pre-post studies were included if they examine the effect of CTOs on service contacts, emergency visits, and violence in individuals with mental illnesses by comparing with control groups or pre-CTO conditions. Conflicts were resolved by consultation of the third independent reviewer. RESULTS Sixteen studies provided sufficient data in the target outcome measures and were included in analysis. Variability in the risk of bias was high among studies. Meta-analyses were conducted separately for case-control studies and pre-post studies. For service contacts, a total of 11 studies with 66,192 patients reported changes in the number of service contacts under CTOs. In 6 case-control studies, a small non-significant increase in service contacts was observed in those under CTOs (Hedge's g = 0.241, z = 1.535, p = 0.13). In 5 pre-post studies, a large and significant increase in service contacts was noted after CTOs (Hedge's g = 0.830, z = 5.056, p < 0.001). For emergency visits, a total of 6 studies with 930 patients reported changes in the number of emergency visits under CTOs. In 2 case-control studies, a small non-significant increase in emergency visits was noted in those under CTOs (Hedge's g = -0.196, z = -1.567, p = 0.117). In 4 pre-post studies, a small significant decrease in emergency visits was noted after CTOs (Hedge's g = 0.553, z = 3.101, p = 0.002). For violence, a total of 2 pre-post studies reported a moderate significant reduction in violence after CTOs (Hedge's g = 0.482, z = 5.173, p < 0.001). CONCLUSION Case-control studies showed inconclusive evidence, but pre-post studies showed significant effects of CTOs in promoting service contacts and reducing emergency visits and violence. Future studies on cost-effectiveness analysis and qualitative analysis for specific populations with various cultures and backgrounds are warranted.

Abstract
OBJECTIVES Suicide is a leading cause of maternal mortality. Suicidality during and around the time of pregnancy can have detrimental impacts on a child's development and outcomes. This paper examines prevalence, demographic characteristics, and timing of initial contact with first responders and health services for a cohort of women who experienced suicidality during and around the time of pregnancy. METHODS Findings are drawn from the Partners in Prevention (PiP) study, a population-wide linked data set of suicide-related attendances by police or paramedics in Queensland, Australia. A sub-cohort of women was identified, who were between 6 months preconception and 2 years postpartum at the time of a suicide-related contact with police or paramedics (PiP-Maternal). Findings are compared to other girls and women who had a suicide-related contact with police or paramedics (PiP-Female). Prevalence, demographic characteristics, timing of contact with first responders and health services, re-presentations, and mortality are reported. RESULTS The PiP-Maternal cohort comprised 3020 individuals and 3400 births. Women in the PiP-Maternal cohort were younger, more likely to be of Aboriginal and/or Torres Strait Islander descent and live outside of a major city than the PiP-Female cohort. There were high rates of out-of-hours calls to police and ambulance, and similar perceived seriousness of the call between women in the PiP-Maternal and PiP-Female cohorts. Women in the PiP-Maternal cohort were less likely to be admitted to an emergency department within 24 hours, even after matching on covariates. Prevalence of suicidality for women who were pregnant and up to 2 years postpartum was 1.32% (95% CI = [1.27, 1.37]). CONCLUSION Vulnerabilities and high rates of contact with police or paramedics, coupled with lower levels of follow-up, highlight the critical need to improve service responses for women with mental health needs during these phases of life.

Abstract
Chronic exposure to Δ-9-tetrahydrocannabinol (THC) during adolescence is associated with long-lasting cognitive impairments and enhanced susceptibility to anxiety and mood disorders. Previous evidence has revealed functional and anatomical dissociations between the posterior vs. anterior portions of the hippocampal formation, which are classified as the dorsal and ventral regions in rodents, respectively. Notably, the dorsal hippocampus is critical for cognitive and contextual processing, whereas the ventral region is critical for affective and emotional processing. While adolescent THC exposure can induce significant morphological disturbances and glutamatergic signaling abnormalities in the hippocampus, it is not currently understood how the dorsal vs. ventral hippocampal regions are affected by THC during neurodevelopment. In the present study, we used an integrative combination of behavioral, molecular, and neural assays in a neurodevelopmental rodent model of adolescent THC exposure. We report that adolescent THC exposure induces long-lasting memory deficits and anxiety like-behaviors concomitant with a wide range of differential molecular and neuronal abnormalities in dorsal vs. ventral hippocampal regions. In addition, using matrix-assisted laser desorption/ionization imaging mass spectrometry (MALDI-IMS), we show for the first time that adolescent THC exposure induces significant and enduring dysregulation of GABA and glutamate levels in dorsal vs. ventral hippocampus. Finally, adolescent THC exposure induced dissociable dysregulations of hippocampal glutamatergic signaling, characterized by differential glutamatergic receptor expression markers, profound alterations in pyramidal neuronal activity and associated oscillatory patterns in dorsal vs. ventral hippocampal subregions.

Abstract
OBJECTIVES The objective of this study is to describe the epidemiological features of each presentation with a primary dermatological diagnosis to a regional emergency department (ED). DESIGN 1-year retrospective audit. SETTING Regional Victorian hospital emergency department. PARTICIPANTS Any presentation to this regional emergency department with a dermatological condition from 1 January 2020 to 31 December 2020. MAIN OUTCOME MEASURES Dermatology presentations to the ED in 2020 and the prevalence of the associated primary diagnosis. RESULTS In total, 4.7% (n = 1873) of ED presentations had a primary dermatological diagnosis. Of these, 1484 were ≥18 years of age and 389 were ≤17 years of age. Cellulitis (26.1%, n = 388) was the most common primary diagnosis among presentations ≥18 years. Non-specific rash was the most common diagnosis (23.6%, n = 92) in presentations ≤17 years. Indigenous Australians ≥18 years were more likely to be in a younger age group (p < 0.01), and dermatitis/eczema presentations ≥18 years (n = 10) were the largest diagnostic group referred to a dermatologist. A total of 134 (7.1%) patients ≥18 years travelled more than 50 km to the ED. There were no dermatological emergencies identified. CONCLUSIONS A high proportion of presentations to this regional ED with a dermatological diagnosis could be well managed by a dermatologist or general practitioner (GP) as an outpatient. The findings of this study inform the need for future rural public dermatology services. Options include teledermatology, or a public weekly or fortnightly rapid review dermatology clinic with a visiting dermatologist, in the absence of a dermatologist onsite.

Abstract
Designing studies of immunotherapy is limited due to a lack of pre-clinical models that reliably predict effective immunotherapy responses. To address this gap, we developed humanized mouse models of colorectal cancer (CRC) incorporating patient-derived xenografts (PDX) with human peripheral blood mononuclear cells (PBMC). Humanized mice with CRC PDXs were generated via engraftment of autologous (isolated from the same patients as the PDXs) or allogeneic (isolated from healthy donors) PBMCs. Human T cells were detected in mouse blood, tissues, and infiltrated the implanted PDXs. The inclusion of anti-PD-1 therapy revealed that tumor responses in autologous but not allogeneic models were more comparable to that of patients. An overall non-specific graft-vs-tumor effect occurred in allogeneic models and negatively correlated with that seen in patients. In contrast, autologous humanized mice more accurately correlated with treatment outcomes by engaging pre-existing tumor specific T-cell populations. As autologous T cells appear to be the major drivers of tumor response thus, autologous humanized mice may serve as models at predicting treatment outcomes in pre-clinical settings for therapies reliant on pre-existing tumor specific T-cell populations.

Abstract
BACKGROUND Identification of circulating tumor DNA (ctDNA) following curative intent therapies is a surrogate for microscopic residual disease for patients with metastatic colorectal cancer (mCRC). Preclinically, in micrometastatic microsatellite stable (MSS) CRC, increased TGF-β signaling results in exclusion of anti-tumor cytotoxic T cells from the tumor microenvironment. Bintrafusp alfa (BA) is a bifunctional fusion protein composed of the extracellular domain of the TGF-βRII receptor ("TGF-β trap") and anti-PD-L1 antibody. METHODS Patients with liver-limited, MSS mCRC and with detected ctDNA after complete resection of all known tumors and standard-of-care therapy were treated with 1200 mg of BA intravenously every 14 days for six doses. The primary endpoint was ctDNA clearance. Radiographic characteristics at recurrence were compared using independent t-tests to historical data from a similar cohort of patients with liver-limited mCRC who underwent observation. RESULTS Only 4 of 15 planned patients received BA before the study was stopped early for loss of equipoise. There was no grade ≥3 AE. None of the patients cleared ctDNA. All patients developed radiographic recurrence by the first planned restaging. Although not detectable at prior to treatment, TGFβ3 was found in circulation in all patients at cycle 2 day 1. Compared to a historical cohort, patients administered BA developed more metastases (15 versus 2, p=0.005) and greater tumor volumes (9 cm vs 2 cm, p=0.05). CONCLUSIONS Treatment with BA in patients with ctDNA-detected, liver-limited mCRC did not clear ctDNA and was associated with large-volume recurrence, highlighting the potential context-specific complexity of dual TGF-β and PD-L1 inhibition.

Abstract
Primary liver tumours (i.e. hepatocellular carcinoma (HCC) or intrahepatic cholangiocarcinoma (ICC)) are among the most frequent cancers worldwide. However, only 10-20% of patients are amenable to curative treatment, such as resection or transplant. Liver metastases are most frequently caused by colorectal cancer, which accounts for the second most cancer-related deaths in Europe. In both primary and secondary tumours, radioembolization has been shown to be a safe and effective treatment option. The vast potential of personalized dosimetry has also been shown, resulting in markedly increased response rates and overall survival. In a rapidly evolving therapeutic landscape, the role of radioembolization will be subject to changes. Therefore, the decision for radioembolization should be taken by a multidisciplinary tumour board in accordance with the current clinical guidelines. The purpose of this procedure guideline is to assist the nuclear medicine physician in treating and managing patients undergoing radioembolization treatment. PREAMBLE: The European Association of Nuclear Medicine (EANM) is a professional non-profit medical association that facilitates communication worldwide among individuals pursuing clinical and research excellence in nuclear medicine. The EANM was founded in 1985. These guidelines are intended to assist practitioners in providing appropriate nuclear medicine care for patients. They are not inflexible rules or requirements of practice and are not intended, nor should they be used, to establish a legal standard of care. The ultimate judgment regarding the propriety of any specific procedure or course of action must be made by medical professionals taking into account the unique circumstances of each case. Thus, there is no implication that an approach differing from the guidelines, standing alone, is below the standard of care. To the contrary, a conscientious practitioner may responsibly adopt a course of action different from that set out in the guidelines when, in the reasonable judgment of the practitioner, such course of action is indicated by the condition of the patient, limitations of available resources or advances in knowledge or technology subsequent to publication of the guidelines. The practice of medicine involves not only the science but also the art of dealing with the prevention, diagnosis, alleviation and treatment of disease. The variety and complexity of human conditions make it impossible to always reach the most appropriate diagnosis or to predict with certainty a particular response to treatment. Therefore, it should be recognised that adherence to these guidelines will not ensure an accurate diagnosis or a successful outcome. All that should be expected is that the practitioner will follow a reasonable course of action based on current knowledge, available resources and the needs of the patient to deliver effective and safe medical care. The sole purpose of these guidelines is to assist practitioners in achieving this objective.

Abstract
Proteins adsorption occurs spontaneously on biomaterial upon insertion within the body. The resulting protein layer influences biomaterial biocompatibility through enhanced bio-integration or, on the contrary, adverse reactions. Furthermore, upon adsorption, proteins can undergo modifications of their structure and, ultimately, their physicochemical properties and activity. Hence, the understanding of protein adsorption on implanted materials appears essential, as exemplified by silicone breast prostheses that might lead to serious health issues. Surface modifications with a bioactive polymer, poly(styrene sodium sulfonate)-polyNaSS, on a hydrophobic silicone surface that composes breast implants, have been successfully performed under UV irradiation by a radical surface polymerization. This strategy enhances cell biocompatibility and antibacterial features. Although detailed insights related to the mechanism are still scarce, polyNaSS is supposed to promote changes in the conformation and/or orientation of adsorbed plasma proteins, reducing the odd for a biofilm to form. The present work addresses more in-depth structural investigations of the adsorbed state of two plasma proteins: Bovine Serum Albumin (BSA), as a model protein, and fibronectin (FN), for its role in cell adhesion. Using Atomic force microscopy (AFM), we report that polyNaSS showed no significant impact on the BSA structure conversely to the FN one. However, imaging findings with AFM clearly outlined a change in the structural organization of FN, going from a nano fibrillar assembly with an average length of 130 nm to a globular one when the surface was grafted. Thus, it is highlighted that polyNaSS interacts specifically with FN. In addition, cell spreading assay of L929 fibroblasts on FN-coated surfaces with optical microscopy indicated no significant impact of the change in FN structure upon fibroblasts adhesion, which displayed active elongated shapes. The present features are crucial for understanding the cell adhesion mechanism induced by surface modification.

Abstract
Darier's disease (also known as keratosis follicularis or dyskeratosis follicularis) is an autosomal dominant inherited disorder which manifests as hyperkeratotic greasy papules in the first or second decade of life. Aside from symptom management and behavioral modifications to avoid triggers, there are currently no validated treatments for Darier's disease (DD). However, a variety of treatments have been proposed in the literature including retinoids, steroids, vitamin D analogs, photodynamic therapy, and surgical excision. The purpose of this review article is to identify therapeutic options for treating DD and to outline the evidence underlying these interventions. A search was conducted in Medline for English language articles from inception to July 4, 2020. Our search identified a total of 474 nonduplicate studies, which were screened by title and abstract. Of these, 155 full text articles were screened against inclusion/exclusion criteria, and 113 studies were included in our review. We identified Grade B evidence for the following treatments of DD: oral acitretin, oral isotretinoin, systemic Vitamin A, topical tretinoin, topical isotretinoin, topical adapalene gel, topical 5-flououracil, topical calciptriol and tacalcitol (with sunscreen), grenz ray radiation, and x-ray radiation. All other evidence for treatments of DD consisted of case reports or case series, which is considered grade C evidence. Considering the quality and quantity of evidence, clinicians may consider initiating a trial of select topical or oral retinoids first in patients with localized or generalized DD, respectively.

Abstract
Abstract
Introduction
Endoscopic biliary stenting is a common procedure, with indications from malignant obstruction to benign stone disease. We discuss a patient who re-presented after endoscopic stenting having been lost to follow up, with a large ‘stentolith’ requiring open CBD exploration.
Case Presentation
A 56-year-old female presented in 2013 with obstructive jaundice and a 2-week history of abdominal pain. She was a smoker, but otherwise had no past medical, surgical, or relevant family history. After initial workup, ERCP with sphincterotomy and pigtail stent placement was performed with interval laparoscopic cholecystectomy in 2014. Post-operative follow up was not arranged, and the patient subsequently re-presented in 2020 with fatigue. MRCP confirmed a proximal CBD stone and linear artefact. Open exploration facilitated removal of the stone-stent complex.
Discussion
Complications of stenting include cholangitis, stent occlusion and migration [2]. Stenting for failed biliary stone extraction is considered a temporary measure, with removal or exchange at three months (1). However, patients may be lost to follow up and return with non-specific symptoms. A rare cause is de novo formation of a gallstone calculus encasing the stent, a phenomenon termed “stentolith” [4]. Proposed pathophysiology is through promotion of bacterial proliferation by the stent, with biofilm formation and calcium bilirubinate precipitation [6]. Variation in formation has been described, with plastic stents developing circumferential stones [12-25], due to potential space between the wall and stent.
Conclusions
This highlights the importance of robust inter-disciplinary working; careful patient follows up and implementation of a mandatory registry at all hospitals for stented patients.

Abstract
BACKGROUND Virtual reality, augmented reality, and mixed reality make use of a variety of different software and hardware, but they share three main characteristics: immersion, presence, and interaction. The umbrella term for technologies with these characteristics is extended reality. The ability of extended reality to create environments that are otherwise impossible in the real world has practical implications in the medical discipline. In ophthalmology, virtual reality simulators have become increasingly popular as tools for surgical education. Recent developments have also explored diagnostic and therapeutic uses in ophthalmology. OBJECTIVE This systematic review aims to identify and investigate the utility of extended reality in ophthalmic education, diagnostics, and therapeutics. METHODS A literature search was conducted using PubMed, Embase, and Cochrane Register of Controlled Trials. Publications from January 1, 1956 to April 15, 2020 were included. Inclusion criteria were studies evaluating the use of extended reality in ophthalmic education, diagnostics, and therapeutics. Eligible studies were evaluated using the Oxford Centre for Evidence-Based Medicine levels of evidence. Relevant studies were also evaluated using a validity framework. Findings and relevant data from the studies were extracted, evaluated, and compared to determine the utility of extended reality in ophthalmology. RESULTS We identified 12,490 unique records in our literature search; 87 met final eligibility criteria, comprising studies that evaluated the use of extended reality in education (n=54), diagnostics (n=5), and therapeutics (n=28). Of these, 79 studies (91%) achieved evidence levels in the range 2b to 4, indicating poor quality. Only 2 (9%) out of 22 relevant studies addressed all 5 sources of validity evidence. In education, we found that ophthalmic surgical simulators demonstrated efficacy and validity in improving surgical performance and reducing complication rates. Ophthalmoscopy simulators demonstrated efficacy and validity evidence in improving ophthalmoscopy skills in the clinical setting. In diagnostics, studies demonstrated proof-of-concept in presenting ocular imaging data on extended reality platforms and validity in assessing the function of patients with ophthalmic diseases. In therapeutics, heads-up surgical systems had similar complication rates, procedural success rates, and outcomes in comparison with conventional ophthalmic surgery. CONCLUSIONS Extended reality has promising areas of application in ophthalmology, but additional high-quality comparative studies are needed to assess their roles among incumbent methods of ophthalmic education, diagnostics, and therapeutics.

Abstract
MOTIVATION DNA methylation is a key epigenetic factor regulating gene expression. While promoter methylation has been well studied, recent publications have revealed that functionally important methylation also occurs in intergenic and distal regions, and varies across genes and tissue types. Given the growing importance of inter-platform integrative genomic analyses, there is an urgent need to develop methods to discover and characterize gene-level relationships between methylation and expression. RESULTS We introduce a novel sequential penalized regression approach to identify methylation-expression quantitative trait loci (methyl-eQTLs), a term that we have coined to represent, for each gene and tissue type, a sparse set of CpG loci best explaining gene expression and accompanying weights indicating direction and strength of association. Using TCGA and MD Anderson colorectal cohorts to build and validate our models, we demonstrate our strategy better explains expression variability than current commonly used gene-level methylation summaries. The methyl-eQTLs identified by our approach can be used to construct gene-level methylation summaries that are maximally correlated with gene expression for use in integrative models, and produce a tissue-specific summary of which genes appear to be strongly regulated by methylation. Our results introduce an important resource to the biomedical community for integrative genomics analyses involving DNA methylation. AVAILABILITY AND IMPLEMENTATION We produce an R Shiny app (https://rstudio-prd-c1.pmacs.upenn.edu/methyl-eQTL/) that interactively presents methyl-eQTL results for colorectal, breast, and pancreatic cancer. The source R code for this work is provided in the supplement. SUPPLEMENTARY INFORMATION Supplementary data are available at Bioinformatics online.

Abstract
79 Background: Microsatellite instability-high (MSI-H) tumors are characterized by deficient mismatch repair, high tumor mutation burden, and exceptional anti-tumor responses to immunotherapy. While durable disease control is often observed for advanced MSI-H cancers treated with immune checkpoint blockade (ICB), some patients (pts) experience treatment resistance. In melanoma and urothelial cancer, acquired resistance to ICB has been associated with increased signaling of the immunosuppressive TGF-β pathway. Bintrafusp alfa (BA) is a first-in-class bifunctional fusion protein composed of the extracellular domain of the TGF-βRII receptor (a TGF-β “trap”) fused to a human IgG1 monoclonal antibody blocking PD-L1. Methods: In this phase II study (NCT03436563), pts with MSI-H metastatic solid tumors who had progressed on prior ICB were eligible. Pts received 1200 mg BA intravenously every 14 days. Paired tumor biopsies were collected for biomarker analysis. The primary objective was to estimate response rate (RR) per iRECIST. Median progression-free survival (PFS) and overall survival (OS) were calculated according to the Kaplan-Meier method. Adverse events (AEs) were assessed according to CTCAE v5.0. Results: 15 pts [arising from the colon/rectum (12), pancreas (1), duodenum (1), appendix (1)] were enrolled. Median duration of prior ICB before progression was 7.2 months (range, 1.8-24). All pts were evaluable for toxicity, and 14 for response. There was 1 grade 3 treatment-related AE (adrenal insufficiency) and 1 grade 5 treatment-related immune AE (hepatic failure). Median number of doses with BA was 4 (interquartile range, 2-4). There were 3 pts with stable disease and 11 with progressive disease as best response. RR was 0% (95% confidence interval (CI), 0-24%), and disease control rate was 21% (95% CI, 5-51%). Median PFS and OS were 1.8 months (95% CI, 1.5-5.7) and 9.1 months (95% CI, 5.3-not estimable), respectively. One pt with colorectal cancer demonstrated sustained stable disease (20.5 months) with BA. Conclusions: Dual inhibition of TGF-β and PD-L1 by BA did not demonstrate significant anti-tumor activity in the majority of pts with MSI-H metastatic cancer who had progressed on prior ICB. One pt did experience prolonged clinical benefit from BA. Ongoing correlative studies may inform on the effect of TGF-β and PD-L1 modulation by BA within the tumor microenvironment. Clinical trial information: NCT03436563.

Abstract
We evaluated outcomes of treatment with 5-fluorouracil (5-FU), doxorubicin, and streptozocin (FAS) in well-differentiated pancreatic neuroendocrine tumors (PanNETs) and its impact on subsequent therapy (everolimus or temozolomide). Advanced PanNET patients treated at our center from 1992 to 2013 were retrospectively reviewed. Patients received bolus 5-FU (400 mg/m2), streptozocin (400 mg/m2) (both IV, days 1-5), and doxorubicin (40 mg/m2 IV, day 1) every 28 days. Overall response rate (ORR) was assessed using RECIST version 1.1. Of 243 eligible patients, 220 were evaluable for ORR, progression-free survival (PFS), and toxicity. Most (≥90%) had metastatic, nonfunctional PanNETs; 14% had prior therapy. ORR to FAS was 41% (95% confidence interval [CI]: 36-48%). Median follow-up was 61 months. Median PFS was 20 (95% CI: 15-23) months; median overall survival (OS) was 63 (95% CI: 60-71) months. Cox regression analyses suggested improvement with first-line versus subsequent lines of FAS therapy. Main adverse events ≥ grade 3 were neutropenia (10%) and nausea/vomiting (5.5%). Dose reductions were required in 32% of patients. Post-FAS everolimus (n = 108; 68% second line) had a median PFS of 10 (95% CI: 8-14) months. Post-FAS temozolomide (n = 60; 53% ≥ fourth line) had an ORR of 13% and median PFS of 5.2 (95% CI: 4-12) months. In this largest reported cohort of PanNETs treated with chemotherapy, FAS demonstrated activity without significant safety concerns. FAS did not appear to affect subsequent PFS with everolimus; this sequence is being evaluated prospectively. Responses were noted with subsequent temozolomide-based regimens although PFS was possibly limited by line of therapy.

Abstract
PURPOSE AT-rich interactive domain 1A (ARID1A) is commonly mutated in colorectal cancer, frequently resulting in truncation and loss of protein expression. ARID1A recruits MSH2 for mismatch repair during DNA replication. ARID1A deficiency promotes hypermutability and immune activation in preclinical models, but its role in patients with colorectal cancer is being explored. EXPERIMENTAL DESIGN The DNA sequencing and gene expression profiling of patients with colorectal cancer were extracted from The Cancer Genome Atlas and MD Anderson Cancer Center databases, with validation utilizing external databases, and correlation between ARID1A and immunologic features. IHC for T-cell markers was performed on a separate cohort of patients. RESULTS Twenty-eight of 417 patients with microsatellite stable (MSS) colorectal cancer (6.7%) had ARID1A mutation. Among 58 genes most commonly mutated in colorectal cancer, ARID1A mutation had the highest increase with frameshift mutation rates in MSS cases (8-fold, P < 0.001). In MSS, ARID1A mutation was enriched in immune subtype (CMS1) and had a strong correlation with IFNγ expression (Δz score +1.91, P < 0.001). Compared with ARID1A wild-type, statistically significant higher expression for key checkpoint genes (e.g., PD-L1, CTLA4, and PDCD1) and gene sets (e.g., antigen presentation, cytotoxic T-cell function, and immune checkpoints) was observed in mutant cases. This was validated by unsupervised differential expression of genes related to immune response and further confirmed by higher infiltration of T cells in IHC of tumors with ARID1A mutation (P = 0.01). CONCLUSIONS The immunogenicity of ARID1A-mutant cases is likely due to an increased level of neoantigens resulting from increased tumor mutational burden and frameshift mutations. Tumors with ARID1A mutation may be more susceptible to immune therapy-based treatment strategies and should be recognized as a unique molecular subgroup in future immune therapy trials.

Abstract
BACKGROUND AND OBJECTIVE Recruiting and retaining male donors remain an ongoing challenge for blood collection agencies. Research suggests that interventions based on costly signalling theory that allows donors to unobtrusively but publicly signal their donor status may be effective. However, what functions as such a signal and how it is interpreted has not been determined. MATERIALS AND METHODS A total of 242 Australian residents (127 female; 115 male) recruited through an online research platform rated their perceptions of a male target wearing (a) no bandage, (b) a regular unmarked bandage or (c) a blood donor branded bandage. RESULTS The target wearing a blood donor branded bandage was rated as significantly more generous by female participants and moral compared to both the target who wore no bandage and the target wearing a regular unmarked bandage. The target wearing the unmarked bandage was perceived as significantly less healthy and competent compared to the target not wearing a bandage. CONCLUSION A public signal of public donor status conveys the generosity and morality of the wearer. The bandage applied to donors after they have donated can act as such an effective signal, but only when these bandages are clearly branded as resulting from donating blood.

Abstract
BACKGROUND CpG island methylator phenotype (CIMP) forms a distinct epigenetic phenotype in colorectal cancer (CRC). Though associated with distinct clinicopathologic characteristics, limited evidence exists of the association of CIMP with patient's reported lifestyle factors and tumor molecular characteristics. We assessed the associations of these characteristics in a pooled analysis of CRC patients. PATIENTS AND METHODS We pooled data from 3 CRC patient cohorts: Assessment of Targeted Therapies Against Colorectal Cancer (ATTACC), biomarker-based protocol (Integromics), and The Cancer Genome Atlas (TCGA). CIMP was measured using the classical 6-gene methylated-in-tumor (MINT) marker panel (MINT1, MINT2, MINT31, p14, p16, and MLH1) in ATTACC and genome-wide human methylation arrays in Integromics and TCGA, respectively. CIMP-High (CIMP-H) was defined as ≥ 3 of 6 methylated markers in ATTACC. In TCGA and Integromics, CIMP-H group was defined on the basis of clusters of methylation profiles and high levels of methylation in tumor samples. Baseline comparisons of characteristics across CIMP groups (CIMP-H vs. CIMP-0) were performed by Student t test or chi-square test for continuous or categorical variables, respectively. Further logistic regression analyses were performed to compute the odds ratio (OR) of these associations. RESULTS Pooled prevalence of CIMP-H was 22% across 3 data sets. CIMP-H CRC tumors were associated with older age at diagnosis (OR, 1.02; 95% confidence interval [CI], 1.01, 1.03), microsatellite instability-high (MSI-H) status (OR, 9.15; 95% CI, 4.45, 18.81), BRAF mutation (OR, 7.70; 95% CI, 4.98, 11.87), right-sided tumor location (OR, 2.40; 95% CI, 1.78, 3.22), poor differentiation (OR, 2.94; 95% CI, 1.95, 4.45), and mucinous histology (OR, 2.47; 95% CI, 1.77, 3.47), as reported previously in the literature. CIMP-H tumors were also found to be associated with self-reported history of alcohol consumption (OR, ever vs. never, 1.58; 95% CI, 1.07, 2.34). Pathologically, CIMP-H tumors were associated with the presence of intraepithelial lymphocytes (OR, 3.31; 95% CI, 1.41, 7.80) among patients in the Integromics cohort. CONCLUSION CIMP-H tumors were associated with history of alcohol consumption and presence of intraepithelial lymphocytes. In addition, we confirmed the previously known association of CIMP with age, MSI-H status, BRAF mutation, sidedness, and mucinous histology. Molecular pathologic epidemiology associations help us explore the underlying association of lifestyle and clinical factors with molecular subsets like CIMP and help guide cancer prevention and treatment strategies.

Abstract
Abstract
Introduction: The need to rapidly collect, integrate, and share data on COVID-19 patients with cancer at scale has given rise to multiple internal and cross-institutional research registries. These registries support use cases that require data at different levels of granularity and are built using mixed standards. Ensuring semantic interoperability and quality of this data is critical for generating reliable and reproducible evidence. At MSK, we created a framework that enabled the rapid development of semantically compatible COVID and cancer registries and data exchange.
Background: Handling and harmonizing real-world data for COVID and cancer research presented with typical challenges: maintenance of complex patient cohorts; reconciling different levels of temporal and semantic granularity; supporting crosswalks between different representations without information loss; and sharing it internally and with research consortia. Solving these challenges for COVID and cancer studies necessitated advanced infrastructure and harmonization solutions.
Methods: We used MSK Extract, our research platform, to create an integrated COVID and cancer data research framework. It included a library of reusable standardized REDCap used in multiple RedCap instances supporting individual research studies; PostgreSQL database containing patient cohorts and data from Electronic Health Records (EHR) standardized to OMOP; and ETL pipelines. Our approach to the REDCap design and data management allowed for combined sets of detailed, atomic, and aggregate-level data through a combination of abstraction, curation, and extraction of data from different sources. We developed reconciliation methodology between initial curation, available raw data, and the subsequent abstraction. We enforced consistent temporal constraints on data extraction and curation. We used the OMOP vocabulary for semantic harmonization, mapping metadata from internal and external registries to OMOP concepts. We linked procedure and medication codes to high-level treatment groups leveraging classifications available in the OMOP vocabulary.
Results: Our approach to the REDCap design supported various analytical use cases and enabled data sharing between different investigators and registries. Reuse of the data that was previously abstracted complemented with the data extracted from EHR allowed investigators and their teams to quickly review, validate, and update the prior curation. Explicit temporal constraints supported alignment between different registries. Using the OMOP standards and high-level treatment classifications supported data conversion between various registries and integration of the data collected via REDCap and sourced from EHR.
Conclusion: Using real-world data for observational COVID and cancer research presented us with opportunities to improve and mature our evolving research infrastructure and better support internal and distributed research, and highlighted the need for uniform data standards in the cancer domain.

Abstract
The Department of Forensic Psychiatry of Castle Peak Hospital is the only facility in Hong Kong that provides territory-wide forensic psychiatric services for patients with criminal involvement. This retrospective study aimed to explore whether the rehabilitation programs provided by the department could significantly reduce the risks of forensic psychiatric inpatients as measured by the Short-Term Assessment of Risk and Treatability (START). START ratings of inpatients who were hospitalized in the department for more than 3 months and were discharged to the community during the period from 11 April 2015 to 31 March 2019 were analyzed. A total of 79 patients were assessed, of whom 61 (77.2%) were males. Fifty-four (68.4%) patients suffered from schizophrenia. START scores upon admission (strength score = 5.67; vulnerability score = 17.43) and upon discharge (strength score = 6.87, vulnerability score = 11.18) indicated significant reduction of risks among inpatients (p < 0.05).

Abstract
BACKGROUND Although the need for whole blood is declining, so too are the number of first-time and repeat blood donors. To develop new recruitment and retention strategies, therefore, we need to draw on as wide a variation in blood donor motivations as possible. The primary aim of this study is to draw on a large survey of donors to develop a broad, theoretically instantiated typology of donor motivations to identify new and less common, yet practically important, motivations that have not been previously reported. STUDY DESIGN AND METHODS Using data from the UK Blood Donor Survey run by NHS Blood and Transplant/Public Health England Epidemiology Unit (N = 61 123 donors), we analyze fixed (N = 52 225) and free (N = 8867) responses to develop a more comprehensive typology of blood donor motivations based on theories from the biology, psychology, philosophy, economics, and sociology of altruism. RESULTS We identified 54 motivations, including a number of newly identified motivations, for blood donations which we organized into 12 superordinate categories (eg, "inspiration via moral elevation," "perceived social closeness," and "fungibility of donations"). These are linked to intervention suggestions such as donating blood in memoriam or donating blood as an alternative to other charitable acts. CONCLUSION We present the most comprehensive account of blood donor motivations to-date. This work also offers a structure for coding free-text responses, developing motivational measures, and identifying tangible interventions. Thus, we feel that this is a valuable resource for blood donor researchers, marketers, and policy makers.

Abstract
4084 Background: Consensus Molecular Subtype 4 (CMS4) colorectal cancer (CRC) features increased TGFβ signaling, which may account for de novo resistance to immunotherapy for patients (pts) with microsatellite stable mCRC. To date, no prior trial has incorporated CMS status as an integral biomarker. Bintrafusp alfa (M7824) is a dual PD-L1 antibody/TGFβ trap with acceptable safety. Methods: Primary tumors from pts with metastatic CRC underwent CMS testing in a CLIA setting. In this Simon two-stage phase II trial (Ho: p < .05; Ha: p≥.25) for CMS4 mCRC, pts received bintrafusp alfa 1200mg IV every 14 days. RT (8Gy/day x 3 days) to a single metastatic lesion with abscopal intent was administered between doses 2 and 3. The primary objective was to estimate response rate (RR) per iRECIST. Correlative studies including RNA sequencing were performed on pre- and on-treatment biopsies. Results: 53 of 137 tested pts (39%) between June 2018-December 2019 had CMS4 mCRC. 13 of 15 treated pts received the agent with RT. All pts were evaluable for toxicity, and 13 for response. Median number of doses was 3 (IQR, 2-4). There was one grade 3 immune-related adverse event (colitis) requiring study discontinuation. There were 2 pts with stable disease and 11 with progressive disease as best response (RR 0%, 95% CI 0-22%). Enrollment was stopped after first stage for futility. Median PFS and OS were 1.6 months and 5.0 months, respectively. In paired samples, treatment with bintrafusp alfa resulted in an increase in the expression of IFNγ signature in nonirradiated metastatic lesions ( p< .001, q< .001). Updated results will be presented. Conclusions: This is the first reported clinical trial to utilize CMS status as an integral biomarker for pts with metastatic CRC and capitalizes on treating CRC subpopulations with targeted agents based upon validated RNA-based signatures. Although the efficacy for bintrafusp alfa and RT is low, changes in IFNγ signature provides a potential signal for refining therapeutic strategies based upon TGFβ enrichment in pts with mCRC. Clinical trial information: NCT03436563 .

Abstract
4061 Background: The consensus molecular subtypes (CMS) have emerged as a novel classification in colorectal cancer (CRC). However, these subtypes, were mostly derived from a US/European population, and have scant data in other ethnic groups. This study aimed to demonstrate molecular subtypes of CRC across geographic regions. Methods: Formalin fixed paraffin embedded (FFPE) tissue from untreated patients with stage II-III colon cancer from Brazil, Canada, Mexico, Thailand, and the US were evaluated. Gene expression profiling was performed at the University of Texas MD Anderson Cancer Center using NanoString’s nCounter technology and an optimized classifier for FFPE. Results: A total of 366 samples were included in this study, evenly distributed between the 5 international sites. While the US population matched previously reported distributions, the distribution of CMS subtypes varied substantially by region (P < 0.0001). While CMS1 was still associated with right-sided tumors (P < 0.001) and deficient mismatch repair (dMMR) (P < 0.001), the prevalence varied between 8% in Brazil to 30% in Mexico. CMS2 was found vary from 14% in Mexico to 47% in Brazil. The metabolic CMS3 subtype was present in only 3% in Thailand, but as high as 19% in Brazil. CMS4 was confirmed to be associated with higher stage (P = 0.047), and the prevalence was lowest in Brazil (14%) compared to 44% and 49% in US and Mexico, respectively. Expansion of study cohort is ongoing. Conclusions: CMS subtype prevalence differs substantially by geographic region in CRC. These variations suggest that transcriptomic-defined disease biology in international populations may be more heterogeneous than previously appreciated. Further studies in global populations are required to validate and extend these findings, which may have important impact for novel therapeutic development.

Abstract
4089 Background: Consensus molecular subtypes (CMS) categorize colorectal cancer (CRC) into groups based on gene transcription and are prognostic in early-stage and first-line metastatic settings. Their impact on treatment history is unknown. We hypothesized that the best prognosis CMS2 would have higher utilization of liver-directed therapies and maintenance chemotherapy over the worst prognosis CMS4. Methods: Primary surgical resection specimens were annotated for CMS on a translational protocol in a 5FU-refractory metastatic CRC population. Specimens that had neoadjuvant chemotherapy or radiation were excluded. CMS1, CMS3 and indeterminate CMS were also excluded. Liver-directed therapies were defined as any surgery, direct injection of cytotoxics or microspheres, radiation or radiofrequency ablation. Multiple occurrences of liver-directed therapies or maintenance chemotherapy in the same patient were recorded once for statistical tests of association. Results: CMS1 (7.4%), CMS3 (8.2%) and indeterminate calls (4.1%) accounted for 20% of all samples tested. There were 43 (44%) CMS2 and 55 (56%) CMS4 patients eligible. Age, stage at diagnosis, mismatch repair and RAS mutational status were similar in both groups. Left-sided tumors were more common in CMS2 (79%) than CMS4 (42%), p = .001. The median overall survival (OS) from stage IV diagnosis was 40 [34 - 51] versus (vs) 28 [21 – 33] months (p < .0001) for CMS2 vs CMS4 respectively. Liver-directed therapy was greater in CMS2 (53%) vs CMS4 (31%), p = .024. The number further increased when multiple treatments in a single patient were taken into account. Microsphere injection, radiation and liver surgery combined with RFA were the most skewed towards CMS2 over CMS4. No difference in median OS was seen from first liver-directed therapy in CMS2 vs CMS4 (29 vs 27 months, p = .31). There was a trend towards greater maintenance chemotherapy in CMS2 (47%) vs CMS4 (29%), p = .076. Conclusions: Better prognosis with CMS2 is consistent with other studies. Significantly increased liver-directed therapy was observed in CMS2. Selection criteria for liver-directed therapy such as slowly progressing, oligometastatic and hepatic-confined disease may be enriching for CMS2 and gives insight into the natural history of this subtype.
