Abstract
INTRODUCTION Detection of alcohol (ETOH) use with biomarkers provides an opportunity to intervene and treat patients with alcohol use disorder before and after liver transplant (LT). We describe our center's experience using urine ethyl glucuronide (EtG) and serum phosphatidylethanol (PEth) in alcohol screening protocols. METHODS Single-center, retrospective review of patients presenting for LT evaluation, patients waitlisted for LT for alcohol-associated liver disease (ALD), and patients who received a LT for ALD over a 12-month period, from October 1, 2019 through September 30, 2020. Patients were followed from waitlisting to LT, or for up to 12 months post-LT. We monitored protocol adherence to screening for ETOH use- defined as completion of all possible tests over the follow-up period- at the initial LT visit, while on the LT waitlist and after LT. RESULTS During the study period, 227 patients were evaluated for LT (median age 57 years, 58% male, 78% white, 54.2% ALD). Thirty-one patients with ALD were placed on the waitlist, and 38 patients underwent LT for ALD during this time period. Protocolized adherence to screening for alcohol use was higher for PEth for all LT evaluation patients (191 [84.1%] vs. 146 [67%] eligible patients, p < .001), in patients with ALD waitlisted for LT (22 [71%] vs. 14 (48%] eligible patients, p = .04) and after LT for ALD, 20 (33 [86.8%] vs. 20 [52.6%] eligible patients, p < .01). Few patients with a positive test in any group completed chemical dependency treatment. CONCLUSIONS When screening for ETOH use in pre- and post-LT patients, protocol adherence is higher using PEth compared to EtG. While protocolized biomarker screening can detect recurrent ETOH use in this population, engagement of patients into chemical dependency treatment remains challenging.

Abstract
Primary myelofibrosis (PMF) is a clonal myeloproliferative neoplasm driven by canonical gene mutations in JAK2, CALR, or MPL in >80% of the cases. PMF that lacks these canonical alterations is termed triple-negative PMF (TN-PMF). The pathologic and genetic characteristics of TN-PMF compared with those of conventional PMF with canonical driver mutations (DM-PMF) have not been well studied. We aimed to identify clinicopathologic and molecular genetic differences between patients with TN-PMF (n = 56) and DM-PMF (n = 89), all of whom fulfilled the 2016 World Health Organization diagnostic criteria for PMF. Compared with the control group, patients in the TN-PMF group were more likely to have thrombocytopenia and less likely to have organomegaly. The bone marrow in patients with TN-PMF showed fewer granulocytic elements and more frequent dyserythropoiesis. Cytogenetic analysis showed a higher incidence of trisomy 8. Targeted next-generation sequencing revealed a lower frequency of ASXL1 mutations but enrichment of ASXL1/SRSF2 comutations. Our findings demonstrated several clinicopathologic and molecular differences between TN-PMF and DM-PMF. These findings, particularly the observed mutation profile characterized by a higher frequency of ASXL1 and SRSF2 comutation, suggest that at least a subset of TN-PMF may be pathogenetically different from DM-PMF, with potential prognostic implications.

Abstract
The widespread Coronavirus Disease 2019 (COVID-19) is caused by infection with the novel coronavirus SARS-CoV-2. Currently, we have a limited toolset available for visualizing SARS-CoV-2 in cells and tissues, particularly in tissues from patients who died from COVID-19. Generally, single-molecule RNA FISH techniques have shown mixed results in formalin fixed paraffin embedded tissues such as those preserved from human autopsies. Here, we present a platform for preparing autopsy tissue for visualizing SARS-CoV-2 RNA using RNA FISH with amplification by hybridization chain reaction (HCR). We developed probe sets that target different regions of SARS-CoV-2 (including ORF1a and N) as well as probe sets that specifically target SARS-CoV-2 subgenomic mRNAs. We validated these probe sets in cell culture and tissues (lung, lymph node, and placenta) from infected patients. Using this technology, we observe distinct subcellular localization patterns of the ORF1a and N regions, with the ORF1a concentrated around the nucleus and the N showing a diffuse distribution across the cytoplasm. In human lung tissue, we performed multiplexed RNA FISH HCR for SARS-CoV-2 and cell-type specific marker genes. We found viral RNA in cells containing the alveolar type 2 (AT2) cell marker gene (SFTPC) and the alveolar macrophage marker gene (MARCO), but did not identify viral RNA in cells containing the alveolar type 1 (AT1) cell marker gene (AGER). Moreover, we observed distinct subcellular localization patterns of viral RNA in AT2 cells and alveolar macrophages, consistent with phagocytosis of infected cells. In sum, we demonstrate the use of RNA FISH HCR for visualizing different RNA species from SARS-CoV-2 in cell lines and FFPE autopsy specimens. Furthermore, we multiplex this assay with probes for cellular genes to determine what cell-types are infected within the lung. We anticipate that this platform could be broadly useful for studying SARS-CoV-2 pathology in tissues as well as extended for other applications including investigating the viral life cycle, viral diagnostics, and drug screening.

Abstract
BACKGROUND Many individuals with mental health problems have comorbid physical conditions, or may present with substance/alcohol misuse or abuse issues. This results in complex treatment challenges that may not be adequately addressed by a model of care that is solely delivered by an individual clinician using a sole intervention. Mainstream pharmacotherapeutic treatment of mental health problems often have limited effectiveness in completely resolving symptoms, and may cause adverse side effects. Adjunctive treatment approaches, including nutraceuticals, lifestyle and behaviour change interventions, are widely used to assist with treatment of mental health problems. However, whilst these can be generally safer with fewer side effects, they have varying levels of evidentiary support. These circumstances warrant reframing the current treatment approach towards a more evidence-based integrative model which may better address the real-world challenges of psychiatric disorders and comorbid physical conditions. In essence, this means developing an integrative model of care which embodies an evidence-informed, personalized stepwise approach using both conventional pharmacological treatments alongside novel adjunctive treatments (where applicable) via the application of a collaborative care approach. DISCUSSION In order to inform this position, a brief review of findings on common patterns of comorbidity in mental illness is presented, followed by identification of limitations of conventional treatments, and potential applications of integrative medicine interventions. Advantages and challenges of integrative mental health care, collaborative models of care, review of research highlights of select integrative approaches, and comment on potential cost advantages are then discussed. We propose that a collaborative care model incorporating evidence-based integrative medicine interventions may more adequately address mental health problems with comorbid medical conditions. Robust research is now required of such a model, potentially within an integrative clinical practice.

Abstract
The present study is the first to empirically test a hierarchical, positive-oriented model of the self and its relationship to second language (L2) achievement motivation, and compare it in three different cultural contexts of Japan, the United States, and Taiwan. Based on the L2 self-model (Lake, 2016), three levels of constructs were developed: Global Self (i.e., Flourishing, Curiosity, and Hope); Positive L2 domain self (i.e., interested-in-L2 self, harmonious passion for L2 learning, and mastery L2 goal orientation); and L2 Motivational Variables (i.e., reading, speaking and listening self-efficacy). A total of 667 students participated in this study, including 181 first-year college students in Japan, 159 high school students in Taiwan, and 327 community college students in the United States. All the participants were learning L2 in school. Results showed that the measures of positive global self, L2 domain self, and L2 motivational self all had a stronger relationship within their respective levels, and progressively weaker relationships as level of generality/specificity became more distal. Furthermore, the relationships among measures varied in the differing cultural contexts with the Japan-based student participants relatively lower on all measures. Implications for teacher educators in the L2 context have been discussed.

Abstract
The present contribution offers an overview of a new area of research in the field of foreign language acquisition, which was triggered by the introduction of Positive Psychology (PP) (MacIntyre and Gregersen, 2012). For many years, a cognitive perspective had dominated research in applied linguistics. Around the turn of the millennium researchers became increasingly interested in the role of emotions in foreign language learning and teaching, beyond established concepts like foreign language anxiety and constructs like motivation and attitudes toward the foreign language. As a result, a more nuanced understanding of the role of positive and negative learner and teacher emotions emerged, underpinned by solid empirical research using a wide range of epistemological and methodological approaches. PP interventions have been carried out in schools and universities to strengthen learners and teachers’ experiences of flow, hope, courage, well-being, optimism, creativity, happiness, grit, resilience, strengths, and laughter with the aim of enhancing learners’ linguistic progress. This paper distinguishes the early period in the field that started with MacIntyre and Gregersen (2012), like a snowdrop after winter, and that was followed by a number of early studies in relatively peripheral journals. We argue that 2016 is the starting point of the current period, characterized by gradual recognition in applied linguistics, growing popularity of PP, and an exponential increase in publications in more mainstream journals. This second period could be compared to a luxuriant English garden in full bloom.

Abstract
PURPOSE To evaluate the safety and efficacy of 0.05 mL intracameral injection of moxifloxacin in patients who underwent phacoemulsification and intraocular lens (IOL) implant. METHODS Retrospective study comprising patients who underwent phacoemulsification and IOL implant between January 2009 and December 2013. Patients were divided into two groups. Group A followed standard endophthalmitis prevention protocol and group B followed the same protocol plus intracameral injection of 0.05 mL of moxifloxacin hydrochloride at 5.45 mg/mL, immediately after IOL implant. RESULTS Medical records from 7,195 eyes of 3,751 patients (median age: 67.8 ± 8.96, range: 48-83 years, 53.8% female) were evaluated. Group A included 3,515 eyes of 1,838 patients and group B included 3,680 eyes of 1,913 patients. The incidence of endophthalmitis in group A was 0.22% (8:3,515 eyes) and in group B was 0.03% (1:3,680 eyes, p=0.0198, Fischer's exact test). No toxicity or inflammation related to the use of moxifloxacin was observed. CONCLUSIONS There was a 7.3-fold lower ratio of endophthalmitis in the group that received moxifloxacin intracameral injection. This study provides further evidence that moxifloxacin is an effective intracameral prophylactic antibiotic.

Abstract
OBJECTIVES This literature review was designed to examine the role of the arts in medical education. It is distinctive from previous literature reviews in that it focuses specifically on what medical education as a discipline can learn from the arts and does not seek to measure the effectiveness of arts-based educational interventions in students or clinicians. METHODS A literature search using the terms 'educat*' or 'medic*' and phrases such as 'arts', 'therapy', 'medicine', 'arts therapy', 'professional artistry' and 'nursing/doctoral education' was conducted. The 60 items identified were filtered for relevance. Key data were extracted from the remaining items and subjected to a literature analysis to identify important or recurring themes. RESULTS A total of 39 pieces of literature were included in the study. Collectively, these outlined four main areas in which the use of the arts impacts upon medical education. These refer to using the arts: (i) as a tool for professional development; (ii) to develop pedagogy; (iii) to critique the prevailing approach of medical education, and (iv) to view practice as a succession of performances. CONCLUSIONS The effectiveness of the arts cannot be measured by yardsticks that have been set for judging technical proficiency or short-term impact. The possible outcomes of embracing the arts in medical education include an enriched view of lifelong learning and professional development, the potential to critique prevailing approaches to medical practice, and the revisualisation of medicine as a succession of performances. These open up the broader social aspects of medical practice to scrutiny and offer new and distinctive ways of exploring professional knowledge and identity.

Abstract
Enteric neurons and blood vessels form intricate networks throughout the gastrointestinal tract. To support the hypothesis of a possible interaction of both networks, we investigated whether primary mesenteric vascular cells (MVCs) and enteric nervous system (ENS)-derived cells (ENSc) depend on each other using two- and three-dimensional in vitro assays. In a confrontation assay, both cell types migrated in a target-oriented manner towards each other. The migration of MVCs was significantly increased when cultured in ENSc-conditioned medium. Co-cultures of ENSc with MVCs resulted in an improved ENSc proliferation and differentiation. Moreover, we analysed the formation of the vascular and nervous system in developing mice guts. It was found that the patterning of newly formed microvessels and neural stem cells, as confirmed by nestin and SOX2 stainings, is highly correlated in all parts of the developing gut. In particular in the distal colon, nestin/SOX2-positive cells were found in the tissues adjacent to the capillaries and in the capillaries themselves. Finally, in order to provide evidences for a mutual interaction between endothelial and neural cells, the vascular patterns of a RET((-/-)) knockout mouse model as well as human Hirschsprung's cases were analysed. In the distal colon of postnatal RET((-/-)) knockout mice, the vascular and neural networks were similarly disrupted. In aganglionic zones of Hirschsprung's patients, the microvascular density was significantly increased compared with the ganglionic zone within the submucosa. Taken together, these findings indicate a strong interaction between the enteric nervous and vascular system.

Abstract
An increasing number of patients older than 65 years are referred for and have access to organ transplantation, and an increasing number of older adults are donating organs. Although short-term outcomes are similar in older versus younger transplant recipients, older donor or recipient age is associated with inferior long-term outcomes. However, age is often a proxy for other factors that might predict poor outcomes more strongly and better identify patients at risk for adverse events. Approaches to transplantation in older adults vary across programs, but despite recent gains in access and the increased use of marginal organs, older patients remain less likely than other groups to receive a transplant, and those who do are highly selected. Moreover, few studies have addressed geriatric issues in transplant patient selection or management, or the implications on health span and disability when patients age to late life with a transplanted organ. This paper summarizes a recent trans-disciplinary workshop held by ASP, in collaboration with NHLBI, NIA, NIAID, NIDDK and AGS, to address issues related to kidney, liver, lung, or heart transplantation in older adults and to propose a research agenda in these areas.

Abstract
BACKGROUND English cancer policy has encouraged primary care trusts (PCTs) to consider their 1-year cancer survival estimates. This study quantifies variation in these estimates across 39 PCTs in the London and South East Coast strategic health authorities, and explores their precision, possible confounding by age and bias due to death certificate only (DCO) registrations. STUDY DESIGN Retrospective observational study. METHODS One-year relative survival estimates and data on DCO registrations for patients diagnosed with lung, colorectal, breast and prostate cancers between 2002 and 2006 were extracted from the UK Cancer Information Service. Direct age standardization was performed with weightings derived from the standard cancer patient population for Europe. Pearson correlation coefficients between survival estimates and DCO proportions were calculated. RESULTS Mean 1-year PCT survival estimates ranged from 6.9 to 19.4 percentage points, and the precision of individual estimates ranged from ±0.9 to ±6.5 percentage points (at 95% confidence level). Age standardization significantly changed the estimates of nine PCTs for breast cancer, five PCTs for lung cancer and three PCTs for colorectal cancer. None of the prostate cancer estimates were affected significantly. DCO proportions were positively associated with lung cancer survival and negatively associated with colorectal and breast cancer survival. CONCLUSIONS PCT 1-year cancer survival estimates may be informative, but caveats relating to data quality and hence the validity of the estimates means that they require careful investigation before naïve use, as random variation, confounding due to age and bias due to DCO registrations may be significant.

Abstract
All applicants to round 1 of national recruitment into the general practice specialty recruitment process were surveyed as to the reasons for, and the timing of their career choices. Most applicants reported decision making after completing undergraduate training citing variety, continuity of care and work-life balance as their main drivers for a career in general practice. Applicants were statistically more likely to have undertaken a Foundation placement in general practice than their peers on a Foundation programme. Reasons for choice of deanery were largely related to location and social ties, rather than to the educational 'reputation' of its programmes.

Abstract
Questions about appropriate allocation of simultaneous liver and kidney transplants (SLK) are being asked because kidney dysfunction in the context of liver failure enhances access to deceased donor organs. There is specific concern that some patients who undergo combined liver and kidney transplantation may have reversible renal failure. There is also concern that liver transplants are placed prematurely in those with end-stage renal disease. Thus to assure allocation of transplants only to those truly in need, the transplant community met in March 2006 to review post-MELD (model for end-stage liver disease) data on the impact of renal function on liver waitlist and transplant outcomes and the results of SLK.

Abstract
Choice of calcineurin inhibitor may be a contributing factor to deteriorating patient and graft survival following liver transplantation for hepatitis C virus (HCV). In our multicenter, open-label LIS2T study, de novo liver transplant patients stratified by HCV status were randomized to cyclosporine or tacrolimus. Follow-up data were obtained in an observational study of 95 patients. Mean follow-up was 34 and 37 months, respectively, for cyclosporine-treated (n = 47) and tacrolimus-treated (n = 48) patients. In patients not receiving antiviral therapy, 22 of 31 given cyclosporine (72%) and 24 of 29 given tacrolimus (83%) had biochemical recurrence of HCV. In 68 patients with at least one biopsy, histological evidence of HCV-related hepatitis was present in 27 of 31 (87%) cyclosporine-treated patients and 37 of 37 (100%) tacrolimus-treated patients (P = .02, chi-square test). Three-year actuarial risk of fibrosis stage 2 was 66% with cyclosporine and 90% with tacrolimus; for fibrosis stage 3 or 4 it was 46% and 80%, respectively. Three graft losses were attributed to HCV recurrence in cyclosporine-treated patients and six in tacrolimus-treated patients. Tacrolimus may be associated with increased risk of histological HCV disease recurrence compared to cyclosporine.

Abstract
INTRODUCTION Modified release (MR) tacrolimus is an extended release formulation administered once daily. The purpose of this pharmacokinetic (PK) study was to evaluate tacrolimus exposure in stable liver transplant recipients converted from Prograf twice a day to MR tacrolimus once daily. METHODS This was an open-label, multicenter study with a single sequence, four-period crossover design. Eligible patients were 18 to 65 years of age, >6 months posttransplant with stable renal and hepatic function and receiving stable doses of Prograf twice a day for >2 weeks prior to enrollment. Patients received Prograf twice a day on days 1 to 14 and 29 to 42. Patients were converted to the same milligram-for-milligram daily dose of MR once daily on days 15 to 28 and 43 to 56. Twenty-four-hour PK profiles were obtained on days 14, 28, 42, and 56. Laboratory and safety parameters were also evaluated. RESULTS Of 70 patients, 62 completed all four PK profiles. The AUC0-24 of tacrolimus was comparable for Prograf twice a day (days 14 and 42) and MR tacrolimus once daily (days 28 and 56). The 90% confidence intervals for MR tacrolimus versus Prograf at steady state (days 28 and 56 vs days 14 and 42) was 0.85 to 0.92 for AUC0-24. MR tacrolimus was well tolerated with a safety profile comparable to that of Prograf. AUC0-24 was highly correlated to Cmin for Prograf (day 14, r = .93; Day 42, r = .89) and for MR tacrolimus (day 28, r = .93; day 56, r = .92). Renal and liver function remained stable. One patient experienced acute rejection. CONCLUSION The steady-state tacrolimus exposure of MR tacrolimus once daily is equivalent to Prograf twice a day after a milligram-for-milligram conversion in stable liver transplant recipients.

Abstract
BACKGROUND A prospective, open-label, study was conducted at 29 centers in 9 countries, involving 307 de novo liver transplant patients to compare the clinical usefulness of monitoring 2-hr post-dose cyclosporine (CsA) levels (C2) with conventional trough cyclosporine blood levels (pre-dose) (C0). METHODS Neoral oral therapy was initiated at 15 mg/kg/day and dose adjusted according to predetermined C2 or C0 target level ranges. The primary efficacy variable was treatment failure at 3 months, where evaluation was based on a composite endpoint of biopsy-proven rejection, treatment for rejection, graft loss, death, or premature withdrawal/discontinuation from the study. RESULTS Baseline characteristics were similar between groups. Graft loss at 12 weeks (retransplantation or death) occurred in 6.8% C2 and in 7.0% C0 patients. Overall incidence of treated acute rejection was lower for C2 (23.6%) than C0 patients (31.6%) (P=0.144, Cochran-Mantel-Haenszel [CMH] test). In hepatitis C virus (HCV)-negative patients, the incidence of rejection in the C2 group was significantly less than in the C0 group (21.2% vs. 33.0%; P<0.05), whereas in HCV-positive patients, the rejection rate was similar in both groups (26.7% for C2 group vs. 27.3% for C0 group: P=0.81). C2 patients (n=16) who reached minimum target CsA levels by day 3 had a notably low incidence of rejection (12.5%), whereas there was no difference in the incidence of rejection in C0 patients, irrespective of time to reach target level. For biopsy-proven acute rejections (21.6% for C2 vs. 30.4% for C0), the incidence of moderate and severe histological diagnosis was significantly lower in the C2 group than in the C0 group (47% vs. 73%; P=0.01). Safety profiles were similar between the two groups, with few patient withdrawals due to adverse events (9.5% for C2; 7.0% for C0). CONCLUSIONS Using C2 monitoring, the overall incidence of acute cellular rejection was lower compared with the C0 group, and the histological severity of acute rejections was shown to be significantly milder for the C2 group, indicative of good long-term prognosis. These data demonstrate that the use of C2 monitoring is superior to C0 and results in a reduction in the incidence and severity of acute cellular rejection without detrimental effect on the drug safety profile.

Abstract
OBJECTIVE The purpose of this study was to define the period of time after which delays in management incurred by investigations cause increased morbidity and mortality. The outcome study is intended to correlate time with death from esophageal causes, overall complications, esophageal related complications, and surgical intensive care unit length of stay. METHODS This was a retrospective multicenter study involving 34 trauma centers in the United States, under the auspices of the American Association for the Surgery of Trauma Multi-institutional Trials Committee over a span of 10.5 years. Patients surviving to reach the operating room (OR) were divided into two groups: those that underwent diagnostic studies to identify their injuries (preoperative evaluation group) and those that went immediately to the OR (no preoperative evaluation group). Statistical methods included Fisher's exact test, Student's T test, and logistic regression analysis. RESULTS The study involved 405 patients: 355 male patients (86.5%) and 50 female patients (13.5%). The mean Revised Trauma Score was 6.3, the mean Injury Severity Score was 28, and the mean time interval to the OR was 6.5 hours. There were associated injuries in 356 patients (88%), and an overall complication rate of 53.5%. Overall mortality was 78 of 405 (19%). Three hundred forty-six patients survived to reach the OR: 171 in the preoperative evaluation group and 175 in the no preoperative evaluation group. No statistically significant differences were noted in the two groups in the following parameters: number of patients, age, Injury Severity Score, admission blood pressure, anatomic location of injury (cervical or thoracic), surgical management (primary repair, resection and anastomosis, resection and diversion, flaps), number of associated injuries, and mortality. Average length of time to the OR was 13 hours in the preoperative evaluation group versus 1 hour in the no preoperative evaluation group (p < 0.001). Overall complications occurred in 134 in the preoperative evaluation group versus 87 in the no preoperative evaluation group (p < 0.001), and 74 (41%) esophageal related complications occurred in the preoperative evaluation group versus 32 (19%) in the no preoperative evaluation group (p = 0.003). Mean surgical intensive care unit length of stay was 11 days in the preoperative evaluation group versus 7 days in the no preoperative evaluation group (p = 0.012). Logistic regression analysis identified as independent risk factors for the development of esophageal related complications included time delays in preoperative evaluation (odds ratio, 3.13), American Association for the Surgery of Trauma Organ Injury Scale grade >2 (odds ratio, 2.62), and resection and diversion (odds ratio, 4.47). CONCLUSION Esophageal injuries carry a high morbidity and mortality. Increased esophageal related morbidity occurs with the diagnostic workup and its inherent delay in operative repair of these injuries. For centers practicing selective management of penetrating neck injuries and transmediastinal gunshot wounds, rapid diagnosis and definitive repair should be made a high priority.
