Abstract
Ochratoxin A (OTA) is a potent mycotoxin produced by Aspergillus and Penicillium spp., which contaminates many crops, including pistachios. Pistachios contaminated with OTA may be subjected to border rejections resulting in significant economic losses to the United States agricultural revenues. The current study examined prevalence of OTA in California grown pistachios and identified its causal agents. OTA was detected in 20% samples from 2018-21 (n=809), with 18% samples exceeding the European Union regulatory limit of 5 µg/kg. Fungi potentially responsible for OTA contamination were isolated from leaves, nuts, and soil collected from 14 pistachio orchards across California. A total of 1,882 isolates of Aspergillus section Nigri and 85 isolates of section Circumdati were recovered. Within section Nigri, 216 (11.5%) isolates were identified as potential OTA producers using a boscalid-resistance assay. Phylogenetic analyses of partial gene sequences for β-tubulin and calmodulin genes resolved section Circumdati into four species: A. ochraceus (33%), A. melleus (28%), A. bridgeri (21%), and A. westerdijkiae (19%). Aspergillus westerdijkiae produced the highest levels of OTA in inoculated pistachios (47 µg/g), followed by A. ochraceus (9.6 µg/g) and A. melleus (3.3 µg/g). Aspergillus bridgeri did not produce OTA. OTA production by section Circumdati was optimal from 20 to 30ºC. All 216 boscalid-resistant isolates from section Nigri were identified as A. tubingensis and representative isolates (n =130) produced 3.8 µg/kg OTA in inoculated pistachios. This is the first detailed report on OTA contamination and causal fungi in California pistachios and will be helpful in devising effective management strategies.

Abstract
BACKGROUND The effect of nonalcoholic steatohepatitis (NASH) on mortality or major adverse cardiovascular events (MACE) in non-liver solid organ transplant recipients (NL-SOT) is unknown. METHODS Using a retrospective design, adult NL-SOT recipients who had biopsy-proven NASH were compared NL-SOT recipients with normal liver function tests and imaging; propensity matched at a 1:10 ratio on the following: age, sex, race, transplant year, transplant organ, smoking status, and diabetes status. Both deceased and living donor recipients were included; heart and liver transplant patients were excluded. Primary outcome was incidence of all-cause mortality and MACE (a composite outcome of coronary artery disease, ischemic stroke, and peripheral arterial disease). RESULTS Seven patients (3 kidney and 4 lung transplants) had biopsy-proven NASH and 70 patients without NASH, both groups were predominantly male (53%-57%), White (86%-91%), and overweight (mean body mass index ∼ 26). The majority of patients were on calcineurin inhibitors (≥85%), antimetabolites (≥97%), and prednisone (≥50%). Survival analysis showed that NASH patients had a higher risk of death (hazard ratio [HR], 3.24; 95% confidence interval [CI], 1.26-8.33, P = 0.02). NASH did not affect the risk of death-censored graft failure (HR, 1.08; 95% CI, 0.14-8.67; P = .94) or the risk of MACE (HR, 1.03; 95% CI, 0.23-4.62; P = .97). CONCLUSIONS In NL-SOT recipients, NASH is significantly associated with mortality but not with MACE.

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
BACKGROUND The Scientific Registry of Transplant Recipients (SRTR) had not traditionally considered biopsy results in risk-adjustment models, yet biopsy results may influence outcomes and thus decisions regarding organ acceptance. METHODS Using SRTR data, which includes data on all donors, waitlisted candidates, and transplant recipients in the United States, we assessed (1) the impact of macrovesicular steatosis on deceased donor yield (defined as number of livers transplanted per donor) and 1-y posttransplant graft failure and (2) the effect of incorporating this variable into existing SRTR risk-adjustment models. RESULTS There were 21 559 donors with any recovered organ and 17 801 liver transplant recipients included for analysis. Increasing levels of macrovesicular steatosis on donor liver biopsy predicted lower organ yield: ≥31% macrovesicular steatosis on liver biopsy was associated with 87% to 95% lower odds of utilization, with 55% of these livers being discarded. The hazard ratio for graft failure with these livers was 1.53, compared with those with no pretransplant liver biopsy and 0% to 10% steatosis. There was minimal change on organ procurement organization-specific deceased donor yield or program-specific posttransplant outcome assessments when macrovesicular steatosis was added to the risk-adjustment models. CONCLUSIONS Donor livers with macrovesicular steatosis are disproportionately not transplanted relative to their risk for graft failure. To avoid undue risk aversion, SRTR now accounts for macrovesicular steatosis in the SRTR risk-adjustment models to help facilitate use of these higher-risk organs. Increased recognition of this variable may also encourage further efforts to standardize the reporting of liver biopsy results.

Abstract
Background Transjugular intrahepatic portosystemic shunt (TIPS) relieves hepatic venous obstruction in Budd-Chiari syndrome (BCS), but the effect on liver function is unclear, particularly outside the immediate post-treatment period. This study aims to evaluate the long-term impact of TIPS on liver function and outcomes in BCS patients. Methods Twenty patients with BCS who underwent TIPS from 1999 to 2018 were included. Demographic data and clinical data at the time of TIPS procedure, 6 months, 12 months, 2 years, 5 years, and 10 years post-TIPS were collected. Results There were 13 (13/20, 65%) women and 7 (7/20, 35%) men with a mean age at the time of TIPS of 42.6 ± 12.8 years. The median time from BCS diagnosis to TIPS was 41 (IQR: 4-165) days. The number of patients with severe ascites decreased significantly from 10/17 (58.8%) at the time of TIPS, to 1/16 (7.7%), 1/13 (7.7%), 2/16 (12.5%), 1/14 (7.1%), and 0/8 (0%) at 6 months, 12 months, 2 years, 5 years and 10 years post-TIPS, respectively. 4/20 (20%) patients developed new hepatic encephalopathy post-TIPS procedure. Child-Pugh score significantly decreased from a score of 9.4 ± 1.8 pre-TIPS to 7.6 ± 1.8 at 6 months, 7.4 ± 1.5 at 12 months, 7.3 ± 1.6 at 2 years, 6.8 ± 1.5 at 5 years, and 6.4 ± 0.7 at 10 years post-TIPS. Fifteen (15/20, 75%) patients required TIPS revision including 4 (4/15, 26.7%) within 30 days, 2 (2/15, 13.3% within 1 month to 1 year, and 9 (9/15, 60%) at more than 1 year. Eight (8/20, 40%) patients underwent liver transplantation (LT) at median time of 7.3 (IQR 3.2-12.9) years after TIPS. Conclusion TIPS placement for BCS results in sustained resolution of symptoms and improved liver function. Despite the frequent need for revisions, the long-term durability of TIPS can forgo the need for LT in the majority of patients.

Abstract
The long-term outcomes of positive crossmatch (+XM) simultaneous liver-kidney (SLK) transplantations are conflicting. We examined the association between crossmatch status and SLK outcomes in recipients discharged on tacrolimus and mycophenolate with or without steroids. We analyzed the Scientific Registry of Transplant Recipients for all primary SLK recipients between 2003 and 2020 with available crossmatch and induction data. We grouped recipients according to the crossmatch status: negative crossmatch (-XM; n = 3040) and +XM (n = 407). Kaplan-Meier curves were generated to examine recipient, death-censored liver, and death-censored kidney survival by crossmatch status. Cox proportional hazard models were used to investigate the association between crossmatch status and outcomes of interest with follow-up censored at 10 years. Models were adjusted for recipient age, sex, diabetes mellitus, Model for End-Stage Liver Disease score, duration on the liver waiting list, induction immunosuppression, steroid maintenance, hepatitis C infection, donor age and sex, local vs. shared organ, cold ischemia time, and previous liver transplantation status. In the univariable analysis, crossmatch status was not associated with recipient survival (log-rank p = 0.63), death-censored liver graft survival (log-rank p = 0.05), or death-censored kidney graft survival (log-rank p = 0.11). Compared with -XM, +XM recipients had a similar 1-year liver rejection rate, but higher kidney rejection rate (4.6% vs. 8.9%, p = 0.002). In the multivariable models, +XM status was not associated with deleterious long-term recipient, liver, or kidney grafts survival. -XM and +XM SLK transplantations have comparable long-term recipient, liver graft, and kidney survival with a slightly increased risk of early kidney allograft rejection in the +XM group. Crossmatch positivity in SLK transplantations should not influence the decision to use organs from a specific donor.

Abstract
Prevalence of latent infections of the canker-causing fungi Botryosphaeria dothidea and species of Cytospora, Diplodia, Lasiodiplodia, Neofusicoccum, and Phomopsis in young shoots of almond, prune, and walnut trees in California was studied to test the hypotheses that latent infections accumulate from current-season shoots to 1-year-old shoots in the orchard and there are distinct associations among pathogen taxa present as latent infections in the same shoot. Samples of newly emerged and 1-year-old shoots were periodically collected in each almond, prune, and walnut orchard for two growing seasons. A real-time quantitative PCR assay was used to quantify latent infection with three parameters: incidence, molecular severity, and latent infection index. Diplodia spp. were absent from most samples. For almond, Lasiodiplodia spp. and Cytospora spp. were detected with a maximum incidence >90%, while B. dothidea and Neofusicoccum spp. incidence was <20% in most cases. In prune orchards, the incidence levels of B. dothidea were >50% in most cases, while those of Cytospora spp. and Lasiodiplodia spp. were 30 to 60% and 30 to 100%, respectively. For walnut, many samplings showed higher incidence in 1-year-old (30 to 80%) than in newly emerged shoots (10 to 50%). Accumulation of latent infection between the two shoot age classes was detected in only a few cases. The percentages of samples showing coexistence of two, three, and four pathogen taxa in the same shoot were 20 to 25, <10, and <5%, respectively. Pairwise associations among pathogen taxa in the same shoot were significant in many cases.

Abstract
There are several choices for induction immunosuppression in kidney-after-liver transplantation. We used the Scientific Registry of Transplant Recipients database. We assessed all kidney-after-liver transplant recipients in the United States between 1/1/2000 and 7/31/2017 to study kidney graft and patient outcomes by induction type. We only included patients discharged on tacrolimus and mycophenolate with or without steroids and had a negative crossmatch before kidney engraftment. We grouped recipients by kidney induction type into the following 3 groups: depletional (n = 550), nondepletional (n = 434), and no antibody induction (n = 144). We studied patient and kidney allograft survival using Cox proportional hazard regression, with transplant center included as a random effect. Models were adjusted for liver induction regimen, recipient and donor age, sex, human leukocyte antigen mismatches, payor type, living donor kidney transplantation, dialysis status, time from liver engraftment, hepatitis C virus status, and the presence of diabetes mellitus at time of kidney transplantation and transplantation year. The 6-month and 1-year rejection rates did not differ between groups. Compared with no induction, neither depletional nor nondepletional induction was associated with an improved recipient or graft survival in the multivariable models. Depletional induction at the time of liver transplantation was associated with worse patient survival after kidney transplantation (hazard ratio [HR], 1.7; 95% confidence interval [CI], 1.09-2.67; P = 0.02). Living donor kidney transplantation was associated with a 48.1% improved graft survival (HR, 0.52; 95% CI, 0.33-0.82; P = 0.00). In conclusion, in the settings of a negative cross-match and maintenance with tacrolimus and mycophenolate, induction use was not associated with a patient or graft survival benefit in kidney-after-liver transplantations.

Abstract
BACKGROUND AND AIMS Proton pump inhibitors (PPIs) may reduce iron absorption and serum ferritin levels in patients with homeostatic iron regulator (HFE)-related hemochromatosis, reducing the need for frequent phlebotomies. Our study aimed to perform for the first time a meta-analysis of existing observational and randomized controlled studies to ascertain the overall effect of PPI use in patients with HFE-related hemochromatosis. METHODS Studies in adults reporting the outcomes of PPIs use in hereditary hemochromatosis patients from Medline, Embase, Scopus and Google Scholar databases from inception to December 2019 were systematically searched. The study outcomes were the serum ferritin levels and annual requirement for phlebotomies. Pooled mean difference, and 95% confidence intervals (CIs) were obtained by the random-effects model. Forrest plots were constructed to show the summary pooled estimate. Heterogeneity was assessed by using I2 measure of inconsistency. RESULTS Following an initial search of 202 manuscripts, a total of three studies involving 68 patients with hemochromatosis (34 in the PPIs group and 34 in the placebo or non-PPI group) were included. A minimum duration of PPI use was 1 year. Patients who received PPIs therapy did not have a statistically significant lower serum ferritin levels (mean difference: -18.86, 95% CI: -60.44, 22.72, P = 0.37, I2 = 88%) but required significantly less sessions of phlebotomies annually (mean difference: -3.10, 95% CI: -4.46, -3.08, P < 0.00001, I2 = 93%). No publication bias was found on Egger (P = 0.94) or Begg (P = 0.98) tests. CONCLUSION PPIs can be used as an adjuvant therapy to reduce phlebotomy burden in patients with HFE-related hemochromatosis.

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
BACKGROUND AND AIMS Biliary complications (BCs) occur in up to 40% of living donor liver transplant (LDLT) recipients. The aim of this study was to evaluate the efficacy of endoscopic therapy in the management of LDLT-related BCs. METHODS A retrospective study of 100 LDLT recipients at a single transplant center over a 9-year period was conducted. BC was defined as a biliary leak and/or a stricture. Patient records were used to identify time to diagnosis, type of intervention, and time to resolution. RESULTS BCs occurred in 46 (46%) patients; median follow-up was 4.6 years (range 5 days-9.3 years); and median time to diagnosis was 37.5 days (range 1 day-3.5 years). BCs were classified as a leak in 6 (6%), stricture in 22 (22%), and a leak + stricture in 18 (18%). ERCP was the initial treatment modality in 43/46 (93%) patients and was completed in 42/43 (98%). Three (6.5%) patients with a leak underwent surgery as the primary treatment approach. The median time to resolution of BCs was 91.5 days (range 21-367). Thirteen patients had a recurrence which was managed with endoscopic therapy alone. CONCLUSIONS Endoscopic therapy was successful in almost all patients (98%) and ERCP alone resulted in successful treatment in a higher proportion of patients (93%) than traditionally reported. Advanced endoscopic techniques obviate the need for PTC and/or surgery and allow successful management in almost all LDLT recipients presenting with BC and in patients with recurrence of strictures.

Abstract
This study evaluated the relative importance of the N arragansett Bay estuary (RI and MA, USA), and associated tidal rivers and coastal lagoons, as nurseries for juvenile winter flounder, Pseudopleuronectes americanus, and summer flounder, Paralichthys dentatus. Winter flounder (WF) and summer flounder (SF) abundance and growth were measured from May to October (2009-2013) and served as indicators for the use and quality of shallow-water habitats (water depth < 1.5-3.0 m). These bioindicators were then analyzed with respect to physiochemical conditions to determine the mechanisms underlying intra-specific habitat selection. WF and SF abundances were greatest in late May and June (maximum monthly mean = 4.9 and 0.55 flounder/m2 for WF and SF, respectively), and were significantly higher in the tidal rivers relative to the bay and lagoons. Habitat-related patterns in WF and SF abundance were primarily governed by their preferences for oligohaline (0.1-5 ppt) and mesohaline (6-18 ppt) waters, but also their respective avoidance of hypoxic conditions (< 4 mg DO/L) and warm water temperatures (> 25 °C). Flounder habitat usage was also positively related to sediment organic content, which may be due to these substrates having sufficiently high prey densities. WF growth rates (mean = 0.25 ± 0.14 mm/d) were negatively correlated with the abundance of conspecifics, whereas SF growth (mean = 1.39 ± 0.46 mm/d) was positively related to temperature and salinity. Also, contrary to expectations, flounder occupied habitats that offered no ostensible advantage in intra-specific growth rates. WF and SF exposed to low salinities in certain rivers likely experienced increased osmoregulatory costs, thereby reducing energy for somatic growth. Low-salinity habitats, however, may benefit flounder by providing refugia from predation or reduced competition with other estuarine fishes and macro-invertebrates. Examining WF and SF abundance and growth across each species' broader geographic distribution revealed that southern New England habitats may constitute functionally significant nurseries. These results also indicated that juvenile SF have a geographic range extending further north than previously recognized.

Abstract
The liver transplant allocation system is currently based upon the Model for End-Stage Liver Disease (MELD) score and allocates organs preferentially to patients with the highest scores (ie, the sickest patients) within a defined geographic unit. In addition, certain patient populations, such as patients with hepatocellular carcinoma and portopulmonary hypertension, receive MELD exception points to account for their increased waitlist mortality, which is not reflected by their MELD score. Significant geographic variation in the access to liver transplantation exists throughout the United States. Both the Organ Procurement and Transplant Network Board of Directors and the Health Resources and Services Administration have determined these geographic disparities to be unacceptable. The liver transplant community has worked to develop methods to reduce these geographic disparities and to reexamine how MELD exception points are granted to certain patient populations. As a result, numerous policy changes have been adopted throughout the years that have broadened the sharing of organs through wider geographic sharing. Despite all of these changes, variation in access to liver transplantation continues to exist, and, thus, the liver transplant community continues to examine new ways to address geographic disparities. This paper reviews several of the key changes to the liver allocation system that have occurred since the implementation of MELD allocation in 2002 and provides an overview of potential changes to the system.

Abstract
BACKGROUND An adult-to-adult living donor liver transplant (LDLT) has emerged as a possible option to help alleviate the organ shortage. The aim of this study was to analyze our experience with biliary complications in LDLT recipients and to identify their risk factors for biliary complications. This paper aimed to describe therapeutic interventions and to evaluate the impact of biliary complications on long-term patient and graft survival rates. METHODS We evaluated biliary complications in a cohort of 120 LDLT recipients at a single institution and studied the impact on long-term graft and patient survival. RESULTS Of the 120 recipients, 26 (21.7%) developed biliary complications. Endoscopy was the initial choice of treatment for recipients with biliary complications. The median time for resolution of bile leaks was 37 days; for resolution of strictures, 82 days. A decreased risk of biliary complications was associated with an interrupted duct-to-duct (versus continuous choledocho-choledochostomy) (hazard ratio [HR]=0.22, P=0.002) and a Roux-en-Y hepaticojejunostomy (HR=0.13, P<0.001). In multivariate analysis of factors associated with graft failure and patient mortality, biliary complications were unrelated to long term (3 and 5 years) graft failure or patient mortality. CONCLUSIONS In our study LDLT recipients had a 21.7% incidence of biliary complications, however, with successful endoscopic techniques, long-term patient and graft survival rates were not negatively affected.

Abstract
BACKGROUND & AIMS This is a phase II multicentre study to investigate the efficacy and safety of avatrombopag (E5501), an investigational second-generation thrombopoietin receptor agonist, administered one week prior to elective procedures in patients with thrombocytopenia secondary to cirrhosis. METHODS Adults with cirrhosis and platelet counts ⩾10 to ⩽58×10(9)/L were randomized to placebo or avatrombopag in two sequential cohorts. Cohort A: placebo vs. one of 3 different doses (100mg loading dose followed by 20, 40, or 80 mg/day on days 2-7) of a first-generation avatrombopag formulation. Cohort B: placebo vs. one of 2 different doses (80 mg loading dose followed by 10 mg/day for days 2-7, or 20mg/day for days 2-4) of a second-generation avatrombopag formulation. Primary end point was achievement of a platelet increase of ⩾20×10(9)/L from baseline and >50×10(9)/L at least once during days 4-8. RESULTS A total of 130 patients were randomized: 93 patients (51, cohort A; 42, cohort B) to avatrombopag and 37 (16, cohort A; 21 cohort B) to placebo. The primary end point was achieved by 49.0% of treated patients in cohort A and 47.6% in cohort B compared to 6.3% and 9.5% of controls; a dose response was seen. Each avatrombopag regimen had a higher proportion of responders compared with their respective cohort placebo arms (p<0.01), except for the 100/40 mg group in cohort A (p=0.17). The most common adverse events were nausea, fatigue, and headache. One patient in the (100/80) avatrombopag group, without a Doppler assessment at screening was diagnosed with portal vein thrombosis during post-treatment follow-up. CONCLUSIONS In this study avatrombopag was generally well-tolerated and increased platelet counts in patients with cirrhosis undergoing elective invasive procedures.

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
AbstractWe present materials development in fabricating thin film devices for the conversion of wind energy as a sustainable energy source. We demonstrate the feasibility of piezoelectric polymer thin film devices to harvest wind energy in a miniature wind tunnel. Using an example of prototype device based on polyvinylidene fluoride (PVDF) thin film devices, we are able to obtain electrical power from the wind’s energy through the mechanical deformation of PVDF, such as that obtained from the films flapping in the wind. We have obtained a preliminary result of 1 mW power (at 15 mph wind) with a single layer of PVDF of 4 x 2 inches and 50 μm in thickness sandwiched between two thin gold electrode films. Additionally, the fracturing of metallic electrodes over time from the induced strain of this application lead to the significance of examining carbon nanotubes as compliant electrodes offering better mechanical properties while maintaining necessary electrical properties.

Abstract
A national conference was held to better characterize the long-term outcomes of liver transplantation (LT) for patients with hepatocellular carcinoma (HCC) and to assess whether it is justified to continue the policy of assigning increased priority for candidates with early-stage HCC on the transplant waiting list in the United States. The objectives of the conference were to address specific HCC issues as they relate to liver allocation, develop a standardized pathology report form for the assessment of the explanted liver, develop more specific imaging criteria for HCC designed to qualify LT candidates for automatic Model for End-Stage Liver Disease (MELD) exception points without the need for biopsy, and develop a standardized pretransplant imaging report form for the assessment of patients with liver lesions. At the completion of the meeting, there was agreement that the allocation policy should result in similar risks of removal from the waiting list and similar transplant rates for HCC and non-HCC candidates. In addition, the allocation policy should select HCC candidates so that there are similar posttransplant outcomes for HCC and non-HCC recipients. There was a general consensus for the development of a calculated continuous HCC priority score for ranking HCC candidates on the list that would incorporate the calculated MELD score, alpha-fetoprotein, tumor size, and rate of tumor growth. Only candidates with at least stage T2 tumors would receive additional HCC priority points.

Abstract
Partial graft liver recipients with graft weight/recipient weight (GW/RW) ratios < 0.8% are thought to have a higher incidence of postoperative complications, including small-for-size syndrome (SFSS). We analyzed a cohort of such recipients and compared those with GW/RW < 0.8% to those with GW/RW >or= 0.8%. Between 1999 and 2008, 107 adult patients underwent partial graft liver transplants: 76 from live donors [living donor liver transplantation (LDLT)] and 31 from deceased donors [split liver transplantation (SLT)]. Of these, 22 had GW/RW < 0.8% (12 with LDLT and 10 with SLT), and 85 had GW/RW >or= 0.8% (64 with LDLT and 21 with SLT). The baseline demographics and median length of follow-up were similar. SFSS developed in 3 recipients with GW/RW < 0.8% (13.6%) and in 8 recipients with GW/RW >or= 0.8% (9.4%; P = not significant). Other early complications were similar between the 2 groups. Inflow modification with splenic artery occlusion was performed in 13 recipients: 7 with GW/RW < 0.8% and 6 with GW/RW >or= 0.8%. Graft survival at 1 year post-transplant did not differ (91% versus 92%; P = not significant). In conclusion, GW/RW did not appear to be the only determinant of outcome after partial liver transplantation. Using techniques such as inflow modification may help to prevent some of the problems seen with smaller grafts.

Abstract
We looked at the impact of delayed splenic artery occlusion (SAO) on recipients with established small-for-size syndrome (SFSS) after partial graft liver transplantation [either from a living donor (LD) or split from a deceased donor (DD)]. Between 1999 and 2007 we performed a total of 100 partial liver transplantations in adult recipients: 66 LD transplantations and 34 DD split transplantations. Of these, 7 (7%) developed SFSS, diagnosed by the clinical features of cholestasis, coagulopathy, and ascites. Mean graft weight/recipient weight (GW/RW) ratio in these 7 recipients was 0.94%. Five of these 7 recipients underwent relaparotomy at a mean of 10 days post-transplantation to rule out a technical complication, and then intraoperative splenic artery ligation was performed. The other 2 recipients were treated radiologically by splenic artery coiling-at 9 and 13 days post-transplantation. Median serum bilirubin at the time of the splenic artery procedure was 20 mg/dL; by 3 weeks postprocedure this had decreased to 2.5 mg/dL. Of the 7 recipients with SFSS, 6 improved and eventually obtained normal graft function; 1 recipient did not improve and ultimately underwent retransplantation because of persistent cholestasis and failure to thrive. Delayed SAO represents a potential option for the treatment of recipients with established SFSS after partial liver transplantation.

Abstract
UNLABELLED Primary biliary cirrhosis (PBC) is sometimes diagnosed based on a positive antimitochondrial antibody in the appropriate clinical setting without a liver biopsy. Although a liver biopsy can assess the extent of liver fibrosis and provide prognostic information, serum fibrosis markers avoid biopsy complications and sampling error and provide results as a continuous variable, which may be more precise than categorical histological stages. The current study was undertaken to evaluate serum fibrosis markers as predictors of clinical progression in a large cohort of PBC patients. Serial liver biopsy specimens and serum samples were collected every 2 years in 161 PBC subjects for a median of 7.3 years. Clinical progression was defined as development of one or more of the following events: varices, variceal bleed, ascites, encephalopathy, liver transplantation, or liver-related death. Serum hyaluronic acid, tissue inhibitor of metalloproteinase 1, and procollagen III aminopeptide were measured and entered into the previously validated enhanced liver fibrosis (ELF) algorithm. The ability of ELF, histological fibrosis, bilirubin, Model for End-Stage Liver Disease (MELD), and Mayo Risk Score to differentiate between individuals who would experience a clinical event from those who would not was evaluated at different time points. Event-free survival was significantly lower in those with high baseline ELF. Each 1-point increase in ELF was associated with a threefold increase in future complications. The prognostic performance of all tests was similar when performed close to the time of the first event. However, at earlier times in the disease process (4 and 6 years before the first event), the prognostic performance of ELF was significantly better than MELD or Mayo R score. CONCLUSION The ELF algorithm is a highly accurate noninvasive measure of PBC disease severity that provides useful long-term prognostic information.
