Abstract
The liver has a unique ability to regenerate1,2; however, in the setting of acute liver failure (ALF), this regenerative capacity is often overwhelmed, leaving emergency liver transplantation as the only curative option3-5. Here, to advance understanding of human liver regeneration, we use paired single-nucleus RNA sequencing combined with spatial profiling of healthy and ALF explant human livers to generate a single-cell, pan-lineage atlas of human liver regeneration. We uncover a novel ANXA2+ migratory hepatocyte subpopulation, which emerges during human liver regeneration, and a corollary subpopulation in a mouse model of acetaminophen (APAP)-induced liver regeneration. Interrogation of necrotic wound closure and hepatocyte proliferation across multiple timepoints following APAP-induced liver injury in mice demonstrates that wound closure precedes hepatocyte proliferation. Four-dimensional intravital imaging of APAP-induced mouse liver injury identifies motile hepatocytes at the edge of the necrotic area, enabling collective migration of the hepatocyte sheet to effect wound closure. Depletion of hepatocyte ANXA2 reduces hepatocyte growth factor-induced human and mouse hepatocyte migration in vitro, and abrogates necrotic wound closure following APAP-induced mouse liver injury. Together, our work dissects unanticipated aspects of liver regeneration, demonstrating an uncoupling of wound closure and hepatocyte proliferation and uncovering a novel migratory hepatocyte subpopulation that mediates wound closure following liver injury. Therapies designed to promote rapid reconstitution of normal hepatic microarchitecture and reparation of the gut-liver barrier may advance new areas of therapeutic discovery in regenerative medicine.

Abstract
Italy has a long history in beef production, with local breeds such as Marchigiana, Chianina, Romagnola, Maremmana, and Podolica which produce high-quality meat. Selection has improved meat production, precocity, growth ability and muscle development, but the genetic determinism of such traits is mostly unknown. Using 33K SNPs-data from young bulls (N = 4064) belonging to these five Italian breeds, we demonstrated that the Maremmana and Podolica rustic breeds are closely related, while the specialised Marchigiana, Chianina, and Romagnola breeds are more differentiated. A genome-wide association study for growth and muscle development traits (average daily gain during the performance test, weight at 1 year old, muscularity) was conducted in the five Italian breeds. Results indicated a region on chromosome 2, containing the myostatin gene (MSTN), which displayed significant genome-wide associations with muscularity in Marchigiana cattle, a breed in which the muscle hypertrophy phenotype is segregating. Moreover, a significant SNP on chromosome 14 was associated, in the Chianina breed, to muscularity. The identification of diverse genomic regions associated with conformation traits might increase our knowledge about the genomic basis of such traits in Italian beef cattle and, eventually, such information could be used to implement marker-assisted selection of young bulls tested in the performance test.

Abstract
Robertsonian translocations, specifically rob(1;29) translocation, have reportedly been the most prevalent chromosomal abnormalities in cattle, affecting various breeds and leading to a decrease in fertility and reproductive value. Currently, the identification of rob(1;29) carriers relies on cytogenetic analysis that has limitations in terms of accessibility, cost, and sample requirements. To address these limitations, a novel genomic biomarker was developed in this study for the rapid and precise identification of rob(1;29) carriers. Using q-PCR, a specific copy number variation associated with translocation was targeted, which effectively distinguished between wild-type, homozygous and heterozygous carriers. Crucially, the biomarker can be applied to DNA extracted from various biological matrices, such as semen, embryos, oocytes, milk, saliva, coat, and muscle, and it is compatible with fresh, refrigerated, or frozen samples. Furthermore, this approach offers significant reductions in cost compared to those associated with traditional cytogenetic analysis and provides results within a short turnaround time. The successful development of this genomic biomarker has considerable potential for widespread adoption in screening programs. It facilitates timely identification and management of rob(1;29) carriers while mitigating economic losses and preserving genetic integrity in bovine populations.

Abstract
In the last two decades, the molecular cause of six monogenic autosomal recessive disorders has been identified in native Italian beef cattle: two different ATP2A1 variants for the pseudomyotonia congenita, the first in Chianina and Romagnola (PMT1) and the second in Romagnola (PMT2); a KDM2B variant for the paunch calf syndrome (PCS) in Marchigiana and Romagnola; a NID1 variant for the congenital cataract (CC) in Romagnola; a LAMB1 variant for the hemifacial microsomia (HFM) in Romagnola; an ABCA12 variant for the ichthyosis fetalis (IF) in Chianina and a FA2H variant for the ichthyosis congenita (IC) in Chianina. The aim of this study was to evaluate the potential impact of these disorders in the affected Italian populations. For this purpose, 3331 Chianina, 2812 Marchigiana and 1680 Romagnola bulls born in the last 40 years were considered. The allelic frequency (AF) of the variant for PMT1 was 1.0% in Romagnola, 4.6% in Marchigiana and 5.9% in Chianina. The AF of the variant for PMT2 was 3.3% in Romagnola and 0% in the other two breeds. The AF of the variant for PCS was 11.7% in Romagnola, 2.0% in Marchigiana and 0% in Chianina. The AF of the variants for CC, HFM, IF and IC resulted below 3%, being the variants detected only in the breed populations in which they were previously reported. Considering a selected male population in the single breed, Chianina showed carrier prevalence of 11.9% for PMT1, 7.7% for IC and 6.4% for IF. Romagnola showed carrier prevalence of 23.4% for PCS, 6.7% for PMT2, 4.1% for HFM, 3.2% for CC and 2.0% for PMT1. Marchigiana showed carrier prevalence of 9.1% for PMT1 and 4.0% for PCS. With respect to the Romagnola cattle, the concerning presence of a total of five defect alleles in the population hampers a general approach based on the prevention of carriers from artificial insemination. However, identification of carriers may allow conscious mating to prevent the risk of homozygous descendants as well as the spread of heterozygous offspring. Therefore, systematic genotyping for all seven known harmful alleles is recommended to prevent risk mating between carriers, in particular to avoid the occurrence of affected offspring.

Abstract
In the last decades, intensive selection programs have led to sustained increases of inbreeding in dairy cattle, a feature that might have adverse consequences on the viability and phenotypic performance of their offspring. This study aimed to determine the evolution of inbreeding of five Italian beef cattle breeds (Marchigiana, Chianina, Romagnola, Maremmana, and Podolica) during a period of almost 20 years (2002–2019). The estimates of Ho, He, Fhat2, and Fped averaged across years (2002–2019) in the studied breeds fluctuated between 0.340–0.401, 0.348–0.392, –0.121–0.072, and 0.000–0.068, respectively. Moreover, annual rates of increase of the estimated inbreeding coefficients have been very low (Fhat2 = 0.01–0.02%; Fped = 0.003–0.004%). The use of a high number of bulls combined with strategies implemented by the Association of Italian Beef Cattle Breeders ANABIC to minimize inbreeding might explain these results. Despite the fact that diversity and inbreeding have remained quite stable during the last two decades, we have detected a sustained decrease of the population effective size of these five breeds. Such results should be interpreted with caution due to the inherent difficulty of estimating Ne from SNPs data in a reliable manner.

Abstract
Low-grade adenosquamous carcinoma is a less frequent variant of metaplastic breast carcinoma, incidentally detected during screening and has an age distribution similar to other breast carcinomas. It shares characteristics with both benign and malignant carcinomas: its mammographic and sonographic features are therefore nonspecific. Breast conserving surgery with adjuvant radiation therapy is currently the preferred therapeutic approach. The aim of this review is to describe the imaging and clinical features of low-grade adenosquamous carcinoma for appropriate identification and diagnosis. The associated pitfalls, histopathologic and epidemiologic factors, natural course, and management of low-grade adenosquamous carcinoma are also discussed.

Abstract
BACKGROUND Vitamin D deficiency has been associated with non-alcoholic fatty liver disease (NAFLD). However, the role of polymorphisms determining vitamin D status remains unknown. OBJECTIVES The objectives of this study were to determine in UK children with biopsy-proven NAFLD (i) their vitamin D status throughout a 12-month period and (ii) interactions between key vitamin D-related genetic variants (nicotinamide adenine dinucleotide synthase-1/dehydrocholesterol reductase-7, vitamin D receptor, group-specific component, CYP2R1) and disease severity. METHODS In 103 paediatric patients with NAFLD, serum 25-hydroxyvitamin D (25OHD) levels and genotypes were determined contemporaneously to liver biopsy and examined in relation to NAFLD activity score and fibrosis stage. RESULTS Only 19.2% of children had adequate vitamin D status; most had mean 25OHD levels considered deficient (<25 nmol·L-1 , 25.5%) or insufficient (<50 nmol·L-1 , 55.3%). Patients had significantly lower 25OHD levels in winter months (95% CI: 22.7-31.2 nmol·L-1 ) when compared with spring (30.5-42.1 nmol·L-1 ; P = 0.0089), summer (36.3-47.2 nmol·L-1 ; P < 0.0001) and autumn (34.2-47.5 nmol·L-1 ; P = 0.0003). Polymorphisms in the nicotinamide adenine dinucleotide synthase-1/dehydrocholesterol reductase-7 (rs3829251, rs12785878) and vitamin D receptor (rs2228570) genes were independently associated with increased steatosis; while a group-specific component variant (rs4588) was associated with increased inflammation in liver biopsies. CONCLUSIONS Children with NAFLD in the UK have particularly low winter vitamin D status, with vitamin D insufficiency prevalent throughout the year. Polymorphisms in the vitamin D metabolic pathway are associated with histological severity of paediatric NAFLD.

Abstract
Aims and Background To describe the cancer prevalence in elderly Italian people and analyze the differences, if any, with the prevalence among younger subjects. Methods & Study Design The cancer prevalence among elderly patients (65 years and over), the three age classes encompassing elderly age (65-74 years, 75-84 years, 85 years and over) and younger patients (0-64 years) was computed using the PREVAL method on the basis of the incident cases over the period 1976-1992 followed up to 31 December 1992 (prevalence reference date). Data were collected by 11 Italian cancer registries. Results The observed prevalence figures for all cancers (except skin epitheliomas), both sexes combined and considering the whole elderly group, were 1,090 and 3,601 cases per 100,000 one and five years since diagnosis, respectively; the prevalence increased up to the 75-84 age group and showed a slight decrease after age 85. With regard to specific cancer sites, in men bladder and prostate had the highest prevalence 5 years from diagnosis (more than 800 cases per 100,000), followed by colon and lung (about 500 cases per 100,000) stomach and rectum (about 300 cases per 100,000); in women breast cancer ranked first (more than 1,000 cases per 100,000), followed by colon (about 350 cases per 100,000), corpus uteri, stomach and rectum cancers (between 150 and 200 cases per 100,000). For all malignancies and the two sexes combined the prevalence figures were about six times higher in the older than in the younger age group. Conclusions These figures confirm the important role of aging in determining the increase in cancer prevalence. The resulting prevalence figures clearly indicate the cancer burden placed on health care services; moreover, the figures will probably increase in the next decades due to a possible improvement in survival and to the dramatic aging of the population, assuming a stable trend for incidence rates. This picture will represent a major challenge for politicians and those dealing with health care planning and social policies in general, especially in the light of the reduction of the available financial resources and the specific features of medical and social needs in the elderly.

Abstract
Aims and background Italy, like most western populations, is sharply aging and changing its age structure with a striking increase in the oldest segment of the elderly. Since age is related to an exponential growth of cancer incidence rates and to a worsening of prognosis, the progressive aging of the population will constitute, in the future, an issue increasingly more important for public health. The present study is the first effort to present and analyze survival rates in Italian elderly cancer patients in order to provide a starting point for the development of better clinical strategies addressed to the aged. Materials and methods The presented data come from a large data set consisting of survival data relating to 25,798 men and 20,479 women, aged 65–84 years at diagnosis, collected by Italian cancer registries participating in the ITACARE project. Relative survival rates of patients have been calculated by sex, quinquennial age classes and the considered entire age class for overall malignant neoplasms and the 10 most frequent cancer sites in the elderly. Results When all Italian data for all cancers in the 65–84 year age group were pooled, survival rates at 5 years from the diagnosis was 27% and 39% in men and women, respectively. As regards specific sites, survival rates below 50% were observed for lung, stomach and ovary cancer at 1 year from diagnosis. At 5 years from diagnosis, the rates were less than 50% for colon, prostate, cervix, multiple myeloma, non-Hodgkin's lymphoma and melanoma (only in men). The best survival at 5 years from diagnosis (above 50%) was in women for melanoma and corpus uteri and breast cancer. For all cancers, the prognosis for women was better in each considered age group even though a dramatic decrease in survival with age was observed in both sexes. In general, a similar decline in survival with increasing age characterized all considered specific sites. However, at closer observation, the patterns of a decrease revealed some differences. The ratio between the survival rates of 55–64 vs 65–84 year age class indicated that the sites with the greatest advantage of survival for younger patients (ratio >1.5) were ovary, lung and melanoma (only in men), whereas the least advantage was observed for colon, corpus uteri, breast and prostate. By calendar periods, excluding non-Hodgkin's lymphoma for women, an increase in survival was observed for all considered sites, improving an encouraging successful trend in diagnostic and therapeutic progresses.

Abstract
Infectious bovine rhinotracheitis (IBR)/infectious pustular vulvovaginitis (IPV) caused by Bovine alphaherpesvirus 1 (BoHV-1) is a significant disease in domestic and wild cattle. In June 2015, the Ministry of Agriculture, Food and Forestry in Italy approved a national surveillance plan to control and eradicate IBR in beef cattle breeds. The objective of this study was to evaluate the results of the first year of the IBR voluntary surveillance plan in Italy. The aim of the plan is to eradicate IBR in all bovines recorded in the National Herd Book for Italian beef cattle breeds over six years. Monetary incentives are used to encourage breeders to achieve the annual seroprevalence ranges stated in the plan. A Ministerial decree states that all bovines in breeding herds and aged older than 12 months should be serologically tested. Serum samples were tested for presence of the antibody to glycoprotein E of BoHV-1 using commercially available enzyme-linked immunosorbent assays. The national herd seroprevalence was 55.49% (95% confidence interval [CI] 52.01-58.92). Of 25,121 bovines tested for antibodies against BoHV-1, 8014 were positive. The seroprevalence in animals from autochthonous Italian cattle breeds was 31.89% (95% CI 31.31-32.47). Seroprevalence was highest in Podolica cattle (55.14%; 95% CI 54.07-56.21), lowest in Maremmana cattle (9.95%; 95% CI 7.99-12.31), and intermediate in Chianina (22.01%; 95% CI 21.03-23.01), Marchigiana (24.85%; 95% CI 23.52-26.23), and Romagnola (15.60%; 95% CI 14.62-16.64) cattle. These seroprevalence rates indicate a need for intervention to decrease the inevitable severe economic losses arising from BoHV-1 infection. Although some regions in Italy have a long history of combatting BoHV-1 infection, only the province of Bolzano has eradicated IBR.

Abstract
The nomenclature and the lack of consensus of clinical evaluation and imaging assessment in groin pain generate significant confusion in this field. The Groin Pain Syndrome Italian Consensus Conference has been organised in order to prepare a consensus document regarding taxonomy, clinical evaluation and imaging assessment for groin pain. A 1-day Consensus Conference was organised on 5 February 2016, in Milan (Italy). 41 Italian experts with different backgrounds participated in the discussion. A consensus document previously drafted was discussed, eventually modified, and finally approved by all members of the Consensus Conference. Unanimous consensus was reached concerning: (1) taxonomy (2) clinical evaluation and (3) imaging assessment. The synthesis of these 3 points is included in this paper. The Groin Pain Syndrome Italian Consensus Conference reached a consensus on three main points concerning the groin pain syndrome assessment, in an attempt to clarify this challenging medical problem.

Abstract
BACKGROUND Rectal neuroendocrine tumours (NETs) are increasingly identified at endoscopy possibly as a result of bowel cancer screening programmes. AIM To present a review of the literature to aid clinicians in the diagnosis and management of rectal neuroendocrine tumours. METHODS A literature search was conducted through MEDLINE using search terms: rectal, rectum, carcinoid, NET, therapy, endoscopy, mucosal resection, submucosal dissection. Relevant articles were identified through manual review with reference lists reviewed for additional articles. RESULTS The incidence of rectal neuroendocrine tumours is approximately 1 per 100 000 population per year with the majority (80-90%) being <1 cm and localised to the submucosa. Metastatic disease is infrequent (<20%) with risk factors including size, atypical appearance, grade and depth of invasion. The primary resection modality influences complete resection rates and the need for secondary therapy. A thorough pre-resection diagnostic work up is required for lesions that are at higher risk of invasion and metastasis. Device-assisted endoscopic mucosal resection and endoscopic submucosal dissection are used to resect localised rectal neuroendocrine tumours <2 cm. Transanal surgery is also used to resect localised 1-2 cm rectal neuroendocrine tumours. Oncological surgical resection is used for rectal neuroendocrine tumours that are >2 cm or with invasion and regional disease. The treatment of advanced disease is multimodal. CONCLUSIONS The long-term tumour biology of small rectal neuroendocrine tumours remains unclear. There is uncertain impact from bowel cancer screening programmes on rectal neuroendocrine tumour incidence, morbidity and mortality. Referral to neuroendocrine tumour centres for patients with locally advanced disease or metastatic disease is recommended.

Abstract
The number of donor organs suitable for liver transplantation is restricted by cold preservation and ischemia-reperfusion injury. We present the first patients transplanted using a normothermic machine perfusion (NMP) device that transports and stores an organ in a fully functioning state at 37°C. In this Phase 1 trial, organs were retrieved using standard techniques, attached to the perfusion device at the donor hospital, and transported to the implanting center in a functioning state. NMP livers were matched 1:2 to cold-stored livers. Twenty patients underwent liver transplantation after NMP. Median NMP time was 9.3 (3.5-18.5) h versus median cold ischaemia time of 8.9 (4.2-11.4) h. Thirty-day graft survival was similar (100% NMP vs. 97.5% control, p = 1.00). Median peak aspartate aminotransferase in the first 7 days was significantly lower in the NMP group (417 IU [84-4681]) versus (902 IU [218-8786], p = 0.03). This first report of liver transplantation using NMP-preserved livers demonstrates the safety and feasibility of using this technology from retrieval to transplantation, including transportation. NMP may be valuable in increasing the number of donor livers and improving the function of transplantable organs.

Abstract
PURPOSE The influence of patient-specific instrumentations on the accuracy of unicompartmental medial knee replacement remains unclear. The goal of this study was to examine the ability of patient-specific instrumentation to accurately reproduce postoperatively what the surgeon had planned preoperatively. METHODS Twenty consecutive patients (20 knees) who suffered from isolated unicompartmental medial osteoarthritis of the knee and underwent medial knee replacement using newly introduced magnetic resonance imaging-based patient-specific instrumentation were assessed. This assessment recorded the following parameters: (1) the planned and the postoperative mechanical axis acquired through long-leg AP view radiographies; (2) the planned and the postoperative tibial slope acquired by means of standard AP and lateral view radiographies; and (3) the postoperative fit of the implanted components to the bone in coronal and sagittal planes. The hypothesis of the study was that there was no statistically significant difference between postoperative results and preoperatively planned values. RESULTS The study showed that (1) the difference between the postoperative mechanical axis (mean 1.9° varus ± 1.2° SD) and the planned mechanical axis (mean 1.8° varus ± 1.2° SD) was not statistically significant; (2) the difference between the postoperative tibial slope (mean 5.2° ± 0.6° SD) and the planned tibial slope (mean 5.4° ± 0.6° SD) was statistically significant (p = 0.008); and (3) the postoperative component fit to bone in the coronal and sagittal planes was accurate in all cases; nevertheless, in one knee, all components were implanted one size smaller than preoperatively planned. Moreover, in two additional cases, one size thinner and one size thicker of the polyethylene insert were used. CONCLUSIONS This study suggests that overall patient-specific instrumentation was highly accurate in reproducing postoperatively what the surgeon had planned preoperatively in terms of mechanical axis, tibial slope and component fit to bone.

Abstract
BACKGROUND Gastric carcinoids (GCs) or neuroendocrine tumours (NETs) are increasingly identified at endoscopy, and account for 0.6-2% of all gastric polyps identified. The SEER database in the US has demonstrated a rising incidence of gastric NETs amongst all NETs; from 2.2% between 1950 and 1969 to 6.0% between 2000 and 2007. AIM To review the literature and assist clinicians in managing patients with GCs. METHODS A literature search was conducted through MEDLINE using search terms: gastric, carcinoid, neuroendocrine tumour, therapy, endoscopy, mucosal resection, submucosal dissection. Relevant articles were identified through manual review. The reference lists of these articles were reviewed to include further appropriate articles. RESULTS There are three types of GCs with important epidemiological, pathophysiological, histological and endoscopic differences that affect prognosis and management. Type 1 and 2 GCs develop in the context of hypergastrinaemia that originates from achlorhydria in atrophic gastritis and a gastrinoma, respectively. Type 3 GCs occur sporadically and independent of gastrin. The histological type, grade and Ki67 index are used to determine prognosis and direct clinical management. Type 1 GCs >1 cm in size and type 2 GCs should be assessed for invasion beyond the submucosa with EUS prior to endoscopic resection with EMR or ESD. Type 3 GCs should be managed as per recommendations for gastric adenocarcinoma. The treatment of advanced disease is multimodal. CONCLUSIONS Patients with gastric carcinoids should be discussed in a specialist neuroendocrine tumour multidisciplinary meeting to ensure all treatment options are explored in localised and advanced disease. Areas of controversy exist that need further research.

Abstract
BACKGROUND Mauriac syndrome is characterised by growth failure, cushingoid appearance and hepatomegaly which occurs in patients with insulin dependent diabetes and was first described shortly after the introduction of insulin as a treatment for the condition. OBJECTIVE To describe the clinical features, histological findings and outcome of young people with glycogenic hepatopathy, the hepatic manifestation of Mauriac syndrome (MS). DESIGN Retrospective cohort study. PATIENTS Young people with glycogenic hepatopathy. SETTING Tertiary paediatric hepatology unit. RESULTS Thirty-one young people (16 M), median age of 15.1 years (IQR 14-16.2) presented within the study period. Median age of diagnosis of diabetes was 10 years (IQR 8-11). Median insulin requirement was 1.33 units/kg/day; median HbA1c was 96.7 mmol/mol (IQR 84.7-112.0). Growth was impaired: median height z-score was -1.01 (-1.73 to 0.4) and median body mass index (BMI) z-score was 0.28 (-0.12 to 0.67). Hepatomegaly was universal with splenomegaly in 16%. Transaminases were abnormal with a median aspartate aminotransferase (AST) of 76 IU/L and gamma glutamyltransferase of 71 IU/L. Liver biopsy was undertaken in 19 (61%). All showed enlarged hepatocytes with clear cytoplasm with glycogenated nuclei in 17. Steatosis was present in the majority. Inflammation was present in 8 (42%). Fibrosis was seen in 14 (73%) and was generally mild though 2 had bridging fibrosis. Megamitochondria were described in 7. Presence of megamitochondria correlated with AST elevation (p=0.026) and fibrosis on biopsy (p=0.007). At follow-up 17 children had normal or improved transaminases, in 13 there was no change. Transaminases followed the trend of the child's HbA1c. CONCLUSIONS Despite modern insulin regimens and monitoring in children with type 1 diabetes, MS still exists. Significant steatosis, inflammation and fibrosis were all seen in liver biopsies.

Abstract
In the absence of adequate compensatory regeneration, overwhelming liver damage can cause acute liver failure (ALF) and death without emergent liver transplantation (LT). Auxiliary LT produces satisfactory outcomes in this setting, with the prospect of native liver regeneration sustaining long-term survival. Since animal models only partially recapitulate human liver regeneration, we investigated the molecular mechanisms controlling it in this unique LT setting, as an exemplar of human liver regeneration. We demonstrate coordinated changes in expression of microRNA (miRNA) during regeneration that drive proliferation, innate immunity and angiogenesis. In contrast, failed regeneration in a similar cohort is associated with distinct miRNA enforcing cell cycle inhibition and DNA methylation. The miRNA expression associated with successful or failed regeneration when recapitulated in vitro, triggered expression of cardinal regeneration-linked genes promoting cell cycle entry or inhibition, respectively. Furthermore, inhibition of miRNA 150, 663 and 503, whose downregulation is associated with successful regeneration, induced cell proliferation which a key determinant of successful regeneration. Our data indicate that human liver regeneration may be orchestrated by distinct miRNA controlling key regeneration-linked processes including hepatocyte proliferation. To our knowledge this is the first characterization of molecular processes associated with human liver regeneration.

Abstract
Meniscal allograft transplantation has emerged as a useful treatment for carefully selected patients. The aim of this review of meniscal allograft transplantation is to put this procedure into a clinical perspective. Since there still is a lack of consensus on how the success of meniscal transplantation should be evaluated it is difficult to compare study outcomes. Nevertheless, almost all studies report an increase in patient satisfaction and improvement in pain and function. Clinical and functional outcome is improved in the majority of patients. Progression of cartilage degeneration according to MRI and radiological criteria was halted in a number of patients, indicating a chondroprotective effect. Joint space narrowing is only significantly progressive at long-term follow-up. On magnetic resonance imaging, shrinkage is seen after some years, but more in lyophilized allografts. Second-look arthroscopy usually shows good healing to the capsule. Overall, the clinical results of this type of surgery are encouraging and long-lasting in a well selected patient population who suffered a total meniscectomy. Meniscal allografting appears to becoming the golden standard therapy for these type of patients.

Abstract
BACKGROUND Non-alcoholic fatty liver disease (NAFLD) is the most common liver disease in children. It is important to distinguish children with more severe disease or steatohepatitis (NASH) from those with the less severe simple steatosis (SS) as prognosis differs. The importance of adipokines in the evolution of NASH is well recognized. OBJECTIVE As adipokines are important in mediating inflammation, they may also be useful biomarkers of disease. METHODS Plasma from 40 children (30 boys), median age 13.4 years, with liver biopsy-proven NAFLD was analysed. Liver biopsies were scored using the NAFLD activity score and compared with adipokine concentrations. RESULTS Median body mass index z-score was 2.12 with a median homeostasis model of assessment- insulin resistance of 4.08. Resistin was lower in NASH than in SS (P = 0.03). Monocyte chemoattractant protein 1 (MCP-1) was also lower in NASH (P = 0.04). MCP-1 was higher in children with severe fibrosis (P = 0.008) with an area under the receiver operating characteristic curve (AUROC) of 0.76. Plasminogen activator inhibitor 1 (PAI-1) was also higher in this group (P = 0.011) with an AUROC of 0.78. There were no significant differences in leptin, adiponectin, adipsin, interleukin (IL) 6, IL10 or tumour necrosis factor α between groups. CONCLUSION PAI-1 MCP-1 and resistin were differentially expressed with increasing severity of NAFLD. Though it is unlikely that this profile alone would serve as a biomarker of disease, differences found may contribute to understanding the role of these mediators in NAFLD.

Abstract
This paper presents a case report of a 27-year-old male patient affected by a large osteochondral defect of the medial femoral condyle (6 cm(2)) in a varus knee. He was treated with a combined approach consisting of high tibial osteotomy and autologous matrix-induced chondrogenesis technique enhanced by a bone marrow-enriched bone graft. Twelve months after surgery, the patient reported considerable reduction in pain and significant increase in his quality of life. A hyaline-like cartilage completely covered the defect and was congruent with the surrounding condyle cartilage as revealed by MRI and by a second-look arthroscopy. Level of evidence IV.

OBJECTIVE To assess the inter- and intra-observer variability of acoustic radiation force impulse (ARFI) quantification in liver segments with influence of age, body mass index (BMI) and liver capsule-to-box (CB) distance. METHODS 10 healthy volunteers were examined twice, by three experienced operators, separated by a 1-week interval. 10 readings were obtained, from segments 3, 5/6 and 7/8. Age, BMI and the CB distance were noted. The Cronbach α statistic for analysis of reliability was performed for the inter- and intra-observer studies. Multivariate linear regression models determined significance of the other parameters. RESULTS 1800 velocity measurements were recorded. Mean values±standard deviation: segment 3, 1.31±0.19 m s(-1); segment 5/6, 1.12±0.22 m s(-1); segment 7/8, 1.12±0.17 m s(-1). For both the inter- and intra-observer study, the Cronbach α statistic was ≥0.7 (reliable) when taken from segments 5/6 and 7/8 but <0.7 (unreliable) for segment 3. BMI and age showed significant (p<0.0001) but contrasting correlation (segment 5/6: BMI r=0.02, age r=-0.02; segment 7/8: BMI r=-0.01, age r=0.01) with ARFI velocities when analysed for the segments deemed reliable. A weak negative correlation between ARFI velocities and liver CB distance was demonstrated for both assessed segments (segment 5/6, r=-0.08; segment 7/8, r=-0.06; p<0.001). CONCLUSION With trained operators, ARFI is a reliable and reproducible method of liver stiffness quantification in segments 5/6 and 7/8 but acquisition of measurements from segment 3 should be avoided. Values obtained deeper to the liver capsule allow more reliable liver stiffness quantification.

Abstract
OBJECTIVE We have previously shown the potential of glycomics to distinguish patients with steatosis from patients with non-alcoholic steatohepatitis (NASH) in an adult population. The pattern of disease in paediatric patients is distinct from adults. The objective of this study was to characterize the N -glycomic profile of children with varying degrees of non-alcoholic fatty liver disease (NAFLD) and identify potential biomarker profiles of disease. METHODS Serum protein N-glycosylation patterns of 51 paediatric NAFLD patients were assessed with deoxyribonucleic acid sequencer-assisted fluorophore-assisted capillary electrophoresis and compared with histology. RESULTS Peak 1 (NGA2F) is the most significantly elevated N-glycan in paediatric NASH patients with peak 5 (NA2) demonstrating the largest decrease. The logarithmically transformed ratio of peak 1 to peak 5 was -0.85 (standard deviation [SD] 0.22) in patients with steatosis and borderline NASH and -0.73 (SD 0.12) in NASH (P = 0.02). The biomarker correlated well with the amount of lobular inflammation with a consistent increase of marker score in ascending stage of lobular inflammation. There was also a trend in differentiating patients with significant fibrosis ≥F2; -0.74 (SD 0.13) from patients with no/minimal fibrosis <F2; -0.86 (SD 0.24), P = 0.06. Analysis of the N-glycans on immunoglobulin G confirmed the undergalactosylation status typical for chronic inflammatory conditions. CONCLUSIONS This study is the first glycomic analysis performed in a paediatric NAFLD population. In agreement with the results obtained in adults, B cells play a dominant role in the N-glycan alterations of paediatric NASH patients.

Abstract
In the last ten years, a multitude of studies focusing on gene expression profiling have attempted to shed light on the molecular and genomic mechanisms leading to hepatocarcinogenesis. One of the downsides of the technology available until recently was that it was limited to RNA extracted from fresh/frozen tissue or cell cultures. Recent advances have made it possible to obtain good quality RNA from formalin-fixed paraffin-embedded (FFPE) tissue, allowing access to a virtually limitless archival resource to be available for retrospective and long-term prospective clinico-pathological studies. Laser-capture microdissection allows the isolation of specific cell populations or of specific microscopic areas of interest from tissue samples. This allows the selective evaluation of gene expression of targeted cell clusters, especially in a very heterogeneous environment as the malignant tissue. In our study, we demonstrated that by laser microdissecting the areas of interest from FFPE tissue we could obtain gene expression signals by running the purified RNA through the Whole Genome DASL assay. A large number of genes were expressed in both subpopulations of hepatocellular carcinoma (classical HCC and cholangiocellular differentiation) as well as in the cirrhotic and non-cirrhotic liver background.

Abstract
Various factors may account for the positive association between meniscal repair and anterior cruciate ligament reconstruction, one being the modulation of healing response of meniscal fibrochondrocytes by growth factors released with intra-articular bleeding and fibrin clot formation. Analysis of vascular endothelial growth factor (VEGF) and its receptors, VEGFR1 and VEGFR2, may be useful in the clinical assessment of bone and soft-tissue remodeling. We measured systemic and local levels of VEGF (VEGF165), VEGFR1 and VEGFR2 after either arthroscopic partial meniscectomy (APM) or single-bundle anterior cruciate ligament reconstruction (ACLR) in order to determine the local effect of bone tunnelling and notchplasty on the release of these growth factors. The study population included 40 patients: 20 consecutive patients had undergone ACLR with hamstring grafts and 20 had undergone APM. Thirty minutes after the end of the operation, knee joint fluid samples were collected via the drainage tube and at the same time venous blood samples were drawn. In both sets of samples, VEGF, VEGFR1 and VEGFR2 concentrations were determined by enzyme-linked immunosorbent assay (ELISA). No significant differences in VEGF, VEGFR1 or VEGFR2 concentrations in the venous blood were observed between the two treatment groups. In contrast, VEGF and VEGFR2 levels were significantly higher in the knee joint fluid of the ACLR group; furthermore, VEGF and VEGFR1 were significantly higher in the knee joint fluid than in the venous blood, whereas VEGFR2 was lower in the knee joint fluid than in the venous blood. Local release of VEGF and its angiogenetic receptor VEGFR2, but not the negative regulator VEGFR1, was significantly higher after ACLR than after APM, indicating a better vasculogenic potential for enhanced bone-graft and meniscus healing. These results could suggest that VEGF and VEGFRs could be considered as good biomarkers of tissue healing after knee joint surgery.

Abstract
AIM The efficacy of PRP in the treatment of tendinopathies has been already studied both in in vitro and in clinical studies. This paper describes the local and the systemic effects of US-guided autologous PRP (Platelet Rich Plasma) injections in chronic tendinopathies in sportspersons. METHODS Fifteen patients (13 male, 2 female) between 17 and 68 years old, affected by chronic tendinopathies at different sites were treated with an echographically guided injection of autologous PRP within the pathological area of the tendons. VISA score and MRI data were collected pre interventions and after 90 days and 24 months from treatment. Changes in different inteleukins (ILs), tumour necrosis factor α (TNF α), interferon γ, vascular endothelial growth factor (VEGF), endothelial growth factor (EGF), chemokine (C-C motif) ligand 2 (CCL2), were analysed at four time points in the peripheral blood of five patients. RESULTS After 90 days the VISA score significantly improved from 36±12 (range 21-64) to 74±17 (range 40-92). Reduction of irregularities was found in 80% of the tendons. After 24 months patients reported an average VISA score of 73±16 (range 42-100). No changes in IL, TNF α and interferon γ were observed. VEGF, EGF and CCL2 decreased progressively from 30m to 3 h after the treatment and returned to near the baselines after 24 h. CONCLUSION PRP injection allow an improvement of the clinical symptomatology, which is well maintained at least for two years from treatment. The PRP-based local therapy could influence systems homeostasis and antidoping evaluations, but, in our opinion, it doesn't represent a doping substance in itself.

Abstract
Severe liver disease in pregnancy is generally considered to have a favorable prognosis. The limited data available have not yielded disease-specific prognostic criteria or guidance on who should undergo liver transplantation (LT). We retrospectively evaluated 54 admissions with pregnancy-related liver disease to (1) evaluate if any admission parameters were associated with death and/or transplantation and (2) identify maternal complications. Eighteen had acute fatty liver of pregnancy and 32 had hypertension/eclampsia related disease. Seven patients (13%) died and four (7%) underwent LT. Survival rates were 43/48 if not listed for LT and 4/6 if listed. Of the four transplanted, three survived. Patients who died and/or underwent LT were more likely to have encephalopathy (p = 0.04) and hyperlactaemia (p = 0.03). Serum lactate was the best discriminant (ROC AUC 0.84). An admission lactate greater than 2.8mg/dL had 73% sensitivity and 75% specificity for predicting death or LT. The addition of encephalopathy to this parameter increased sensitivity and specificity to 90% and 86%, respectively. The King's College criteria were not effective in predicting outcome. This study confirms the overall favorable prognosis in pregnancy-related liver failure but indicates that elevated lactate levels in the presence of encephalopathy best identify patients at greatest risk of death or LT.

Abstract
Recurrent hepatitis C is a common cause of graft loss in patients undergoing liver transplantation, and serial protocol liver biopsies have been used to identify patients at risk of graft loss from rapid fibrosis progression. The aim of this study was to derive a simple noninvasive index to predict fibrosis in patients with recurrent hepatitis C post-transplant. A retrospective study was performed assessing serial liver biopsies for post-transplant chronic hepatitis C infection. One hundred eighty-five patients were included in the analysis; median age 53 years (interquartile range 48-59) and 140 (76%) were male. Liver histology showed 53 (29%) had Ishak fibrosis stages F0/F1, 31 (17%) had F2, 29 (16%) had F3, 19 (10%) had F4 and 53 (29%) had F5/F6. The London Transplant Centres' (LTC) score was derived combining aspartate aminotransferase (AST IU/L), time from liver transplant (TFLT months), international normalized ratio and platelets. Diagnostic accuracy of the LTC score was assessed using area under receiver-operating characteristic (ROC) curves. The area under the ROC curve for moderate fibrosis (F >or= 2) was 0.78 (95% CI, 0.70-0.86; P < 0.0001), for advanced fibrosis (F4-6) was 0.80 (95% CI, 0.72-0.87; P < 0.0001) and for cirrhosis was 0.80 (95% CI, 0.72-0.88; P < 0.0001). An optimal cut-off value of 6.3 distinguished patients with no or mild fibrosis (F <or= 1) odds ratio 10.8 (95% CI, 5.1-22.9); P < 0.0001), sensitivity 88%, specificity 60%, negative predictive value 67% and positive predictive value 84%. The LTC score can identify patients with Hepatitis C virus recurrence following liver transplant with a low risk of significant fibrosis, thus avoiding the need for protocol biopsy.

Abstract
Historically, liver biopsy (LB) was the sole method to evaluate the severity of hepatic fibrosis in patients with chronic hepatitis C infection. However, LB is expensive and associated with a risk of severe complications. Therefore, noninvasive tests have been developed to assess the severity of liver fibrosis. The accuracy of Fibroscan (FS) and King's score (KS) was evaluated individually and in combination using liver histology as the reference standard. One hundred and eighty-seven patients were identified who had undergone a biopsy with a diagnosis of chronic hepatitis C virus (HCV) mono-infection (HCV RNA-positive by RT-PCR), attending King's College Hospital (n = 88) or the Royal Free Hospital (n = 99) (London) between May 2006 and December 2007. Liver fibrosis was scored using the Ishak method; significant fibrosis was defined as Ishak fibrosis stage F3-F6, and cirrhosis defined as Ishak fibrosis F5-F6. The diagnostic accuracy of each test was assessed by area under receiver operator characteristic curves (AUROC). Median age was 49 years (43-54) and 115 (61%) were male. The AUROC for FS, KS and FS + KS for the diagnosis of Ishak F3-F6 were 0.83, 0.82 and 0.85, respectively and for the diagnosis of cirrhosis (>or=F5) were 0.96, 0.89 and 0.93, respectively. The negative predictive values for the diagnosis of cirrhosis using the optimal cut-off results for fibrsocan (10.05 kPa), KS (24.3) and the two combined (26.1) were 98%, 91% and 94%, respectively. The noninvasive markers and, particularly, FS were effective tests for the prediction of cirrhosis in chronic hepatitis C. Both KS and FS also had clinical utility for the prediction of Ishak fibrosis stages F3-F6.

Abstract
The impact of steatosis on treatment response in chronic hepatitis C infection is controversial. The aim of this study was to determine whether steatosis +/- steatohepatitis on pre-treatment liver biopsy influenced sustained virological response (HCV RNA negative 6 months after completing therapy) in patients with chronic hepatitis C infection treated with pegylated interferon-alpha and ribavirin. One hundred and seventy-nine patients, median age 46 years (interquartile range 40-52), treated between 2001 and 2005. Histological evidence of steatosis was present in 93 patients (52%) and steatohepatitis in 33 patients (18%), 31 patients (17.3%) were cirrhotic. There were 106 (59%) responders, who were similar to non-responders in respect to gender, age, and pre-treatment ALT. On univariate analysis, infection with genotype 2 or 3 was associated with sustained virological response (odds ratio 6.5 (95% CI, 3.3-12.5); P < 0.0001), whereas cirrhosis and patient weight were associated with a reduced response (odds ratios 0.23 (95% CI, 0.11-0.48); P < 0.0001, and 0.97 (95% CI, 0.95-0.99); P < 0.01, respectively); steatohepatitis but not steatosis impacted on the likelihood of achieving sustained virological response (odds ratio 0.37 (95% CI, 0.17-0.77); P = 0.009, and P = 0.18, respectively). Multivariate analysis revealed that infection with genotype 1 or 4 (odds ratio 0.09 (95% CI, 0.03-0.32); P < 0.001) and pre-treatment weight (odds ratio 0.94 (95% CI, 0.90-0.98); P = 0.002) were the only variables associated independently with sustained virological response. In chronic hepatitis C infection, although steatosis was associated with steatohepatitis, neither was shown to affect sustained virological response, which was influenced by genotype, patient weight and the presence of cirrhosis.

Abstract
Since patients with hepatitis C virus (HCV) often have hepatic steatosis, this retrospective analysis aimed to assess whether steatosis influences fibrosis progression. We studied 112 HCV RNA positive subjects (median age 44, IQR 39-51 years), who had two liver biopsies performed (median biopsy interval 50, 34-74 months). Fibrosis was staged using the Ishak method and steatosis by the Kleiner system (<5% steatosis = S0, 5-33% = S1, 33-66% = S2, and >66% = S3). The subjects were untreated because they had mild fibrosis (n = 59), declined therapy (n = 48), or had co-existing disease precluding treatment (n = 5). On first liver biopsy, 60 (54%) had S0, 34 (30%) had S1, 12 (11%) had S2, and 6 (5%) had S3. Steatosis was associated with genotype 3, odds ratio 4.8 (95% CI 1.3-16.7, P = 0.02). Twenty-three patients (21%) had disease progression on the second biopsy, defined as an increase in Ishak score by > or =1 stage. On univariate analysis, fibrosis progression was associated with older age (P = 0.004), higher AST (P = 0.04), and steatosis (P = 0.005) but on multivariate analysis, only baseline steatosis was significant, odds ratio 14.3 (2.1-111.1, P = 0.006). Kaplan-Meier analysis demonstrated that steatosis impacted on time to progression to both significant fibrosis (Ishak > or =F3) and cirrhosis (Ishak F5-6) (P = 0.001 and P = 0.049, respectively). The finding that steatosis was significantly associated with fibrosis progression indicates that, independent of baseline fibrosis stage, patients should be considered for anti-viral treatment if steatosis is present. Furthermore, strategies to reduce steatosis may have a beneficial effect on fibrosis progression and, therefore, patient outcome.

Abstract
The natural killer (NK) cell receptor, NKG2D is a member of the c-type lectin-activating receptor family. It is expressed by all NK cells and by a sub-population of CD8+ T cells. NKG2D engagement with its ligands directly activates NK cells and acts as a co-stimulator on CD8+ T cells. Recent reports, however, have demonstrated a role for NKG2D in direct T-cell activation in chronic inflammation. The aim of this study was to investigate the pattern of expression and the functional role of NKG2D on circulating and intrahepatic CD8+ T cells in chronic viral hepatitis. Peripheral blood lymphocytes and intrahepatic lymphocytes from 45 patients with chronic viral hepatitis (HBV and HCV) were studied. Phenotypic NKG2D expression and its functional ability to activate intrahepatic and circulating lymphocytes were analysed. Intrahepatic CD8+ T cells display increased NKG2D expression in chronic viral hepatitis in comparison with circulating CD8+ T cells. NKG2D co-stimulates intrahepatic CD8+ T cells and hepatitis B virus-specific CD8+ T cells. However, we could not demonstrate an ability to directly activate CD8+ T cells through the NKG2D signalling pathway alone. NKG2D is up-regulated on intrahepatic CD8+ T cells in type B and C chronic viral hepatitis; however, its function appears to be restricted to that of a co-stimulatory molecule.

Abstract
Pancreatic cancer is the second commonest malignant gastrointestinal neoplasm. Modern imaging techniques have greatly increased sensitivity in diagnosing and staging pancreatic cancers. Multidetector CT in particular, plays a critical role in local staging and determining the resectability of pancreatic tumours. MR and endoscopic ultrasound are valuable in those groups of patients in whom CT findings alone are inconclusive in tumour characterisation and local staging, particularly vascular involvement. In this article we review the current established concepts and the role of imaging in the multidisciplinary management of pancreatic tumours together with a comprehensive review of the literature.

Abstract
AIMS To analyse the histological features of 33 patients (48 biopsy specimens) with a clinicopathological diagnosis of graft vs. host disease of the liver (L-GVHD). RESULTS The time of biopsy post-haematopoietic stem cell transplantation (HSCT) ranged from 22 to 1082 days (median 144 days). Bile duct damage (BDD) was present in all biopsies except one. The bile duct to portal ratio ranged from 0.3 to 1 (median 0.8). Moderate/severe lobular hepatitis was present in 11 biopsies. Endotheliitis was present in four biopsies (8%). The majority of the biopsies showed none [25 (52%)] or mild [17 (35%)] fibrosis. The only significant difference between biopsies earlier ("acute") or later ("chronic" GVHD) than 100 days post-HSCT was the presence of portal inflammation in the "chronic" GVHD group. CONCLUSION BDD is the predominant change in L-GVHD. In about a quarter of biopsies the appearance may be of a lobular hepatitis. L-GVHD is not a fibrogenic process. The significance of separating acute versus chronic L-GVHD based on a cut-off of 100 days post-HSCT is questionable. Further studies are needed to understand the relationships between the mechanisms of BDD, bile duct loss and regeneration.

Abstract
BACKGROUND Transjugular liver biopsy (TJLB) can be performed to obtain more than two cores safely. This advantage has not been evaluated in terms of diagnostic accuracy or grading/staging evaluation. AIM To evaluate whether three separate cores of TJLB provide more histological information compared with two or one cores. METHODS Twenty-three patients, who had three separate passes, with each core >/=7mm in length using a 19G Tru-cut needle, were evaluated. Each TJLB was blindly coded; the pathologist randomly assessed: (a) each core separately covering the other two, (b) two cores simultaneously covering the third and (c) the three cores together for diagnostic yield, inflammation and fibrosis. RESULTS The mean TJLB length was 32+/-5.5mm. In 12 one-core (52%) and 18 2-core (78%) assessments, diagnosis (mainly cirrhosis) was made correctly in each core. The within-patient standard deviations for one-core vs two-core assessment were similar for grading (0.42 and 0.47, respectively), but higher for staging (0.39 and 0.15, respectively). Staging was underestimated in assessing one-core and less for two cores compared to three cores. CONCLUSION Three non-fragmented cores (each core >/=7mm in length) of TJLB can be considered a minimum requirement for histological assessment, giving better reproducibility in diagnosis as well as for inflammation and fibrosis.
