Abstract
INTRODUCTION AND AIMS Fibrosis staging in patients with nonalcoholic fatty liver disease (NAFLD) is carried out through the application of stepwise algorithms but there is little real-world data on their use. Our aim was to calculate the number of patients with NAFLD and indeterminate or high risk for fibrosis, assessed through noninvasive scores, that consequently underwent further staging evaluation. MATERIALS AND METHODS A cross-sectional multicenter cohort study was conducted on patients with NAFLD evaluated by hepatologists within the time frame of June 1 and July 31, 2018. The FIB-4 and NAFLD fibrosis scores were calculated in all the patients, and if at least one of the scores suggested indeterminate or high risk for fibrosis, we believed the patient should have undergone additional fibrosis staging assessment. RESULTS The study included 238 patients. The median time interval from NAFLD diagnosis and inclusion in the analysis was 12.2 months (IQR 3.0-36.5). A total of 128 (54%) patients had at least one noninvasive score that suggested indeterminate or high risk for fibrosis but studies to confirm the fibrosis grade (elastography, biopsy, etc.) were performed on only 72 (56%). The main barriers encountered by the physicians for applying the staging algorithms were related to health insurance coverage and imaging study costs. CONCLUSIONS A high percentage of patients with NAFLD were at indeterminate or high risk for fibrosis, according to noninvasive scores, but additional studies were carried out on only half of them, showing low adherence to current recommendations.

Abstract
Optimal management of gilt reproduction requires oestrus synchronization. Hormonal treatments are used for this purpose, but there is a growing demand for non-hormonal alternatives, especially in organic farms. The boar effect is an important alternative opportunity to induce and synchronize oestrus without hormones. Before puberty, gilts exhibit a 'waiting period' during which boar exposure could induce and synchronize the first ovulation. We searched for salivary biomarkers of this period of boar effect receptivity to improve detection of the gilts to stimulate with the perspective of enhancing the efficacy of the boar effect. Saliva samples were collected from 30 Large-White×Landrace crossbred gilts between 140 and 175 days of age. Gilts were exposed twice a day to a boar and subjected to oestrus detection from 150 to 175 days of age. Among the 30 gilts, 10 were detected in oestrus 4 to 7 days after the first introduction of the boar and were considered receptive to the boar effect, 14 were detected in oestrus more than 8 days after first boar contact, and six did not show oestrus and were considered non-receptive. Saliva samples from six receptive and six non-receptive gilts were analyzed for steroidome and for metabolome using gas chromatography coupled to tandem mass spectrometry and 1H nuclear magnetic resonance spectroscopy, respectively. Four saliva samples per gilt were analyzed: 25 days and 11 days before boar introduction, the day of boar introduction, 3 days later for receptive gilts or 7 days later for non-receptive gilts. Twenty-nine steroids and 31 metabolites were detected in gilt saliva. Salivary concentrations of six steroids and three metabolites were significantly different between receptive and non-receptive gilts: progesterone and glycolate 25 days before boar introduction, 3α5β20α- and 3β5α20β-hexahydroprogesterone, dehydroepiandrosterone, androstenediol, succinate, and butyrate 11 days before boar introduction, and 3β5α-tetrahydroprogesterone on the day of boar introduction. Thus, nine potential salivary biomarkers of boar effect receptivity were identified in our experimental conditions. Further studies with higher numbers of gilts and salivary sampling points are necessary to ascertain their reliability.

Abstract
INTRODUCTION There is a lack of information regarding outcomes after liver transplant in Latin America. OBJECTIVES This study sought to describe outcomes after liver transplant in adult patients from Argentina. METHODS We performed an ambispective cohort study of adult patients transplanted between June 2010 and October 2012 in 6 centers from Argentina. Only patients who survived after the first 48 hours postransplantation were included. Pretransplantation and posttransplantation data were collected. RESULTS A total of 200 patients were included in the study. Median age at time of transplant was 50 (interquartile range [IQR] 26 to 54) years. In total, 173 (86%) patients had cirrhosis, and the most frequent etiology in these patients was hepatitis C (32%). A total of 35 (17%) patients were transplanted with hepatocellular carcinoma. In patients with cirrhosis, the median Model for End-Stage Liver Disease (MELD) score at time of liver transplant was 25 (IQR 19 to 30). Median time on the waiting list for elective patients was 101 (IQR 27 to 295) days, and 3 (IQR 2 to 4) days for urgent patients. Almost 40% of the patients were readmitted during the first 6 months after liver transplant. Acute rejection occurred in 27% of the patients. Biliary and vascular complications were reported in 39 (19%) and 19 (9%) patients, respectively. Renal failure, diabetes, and dyslipidemia were present in 40 (26%), 87 (57%), and 77 (50%) at 2 years, respectively. CONCLUSIONS We believe the information contained in this article might be of value for reviewing current practices and developing local policies.

Abstract
To date, selective blockade of Toll-like receptor (TLR) signalling has been developed as a new approach for treatment for many inflammatory diseases. As β-D-mannuronic acid (M2000) has been known as an anti-inflammatory molecule in several experimental models, we investigated the antagonistic effects of M2000 on TLR2 and TLR4 downstream signalling transduction pathway in human embryonic kidney (HEK) 293 cell lines overexpressing TLR2/CD14 and the TLR4/MD2/CD14 complex, respectively. M2000 effectively inhibited mRNA expression of MyD88 and p65, major subunit of nuclear factor-κB, in HEK293 cells stimulated by lipoteichoic acid (LTA, a TLR2 agonist) and lipopolysaccharide (LPS, a TLR4 agonist) with no evidence of cytotoxicity. In addition, M2000 also suppressed LTA and LPS-induced production of TNF-α and IL-6 inflammatory cytokines in these cells. Furthermore, the results revealed that M2000 had no significant effect on Tollip mRNA expression as a negative regulator of TLR signalling in aforesaid cells. Overall, these data point to M2000 inhibitory effect on Toll-like receptor (TLR) 2, 4 signalling in HEK293 cells. This information might provide new insights into the possible roles of this small drug in order to introduce it as a TLR signalling pathway inhibitor. However, more studies are needed to confirm β-D-mannuronic acid antagonistic effects including the effects of M2000 on peritoneal isolated macrophages and also on blood cells in patients with inflammatory diseases such as ankylosing spondylitis.

Abstract
OBJECTIVE To measure the association between readmission after liver transplantation and corresponding adverse drug reactions. METHODS A total of 48 patients undergoing liver transplantation were prospectively followed for 1 year. Of these, 23 were readmitted and evaluated by a pharmacist for causes of adverse drug reaction. The detection of adverse drug reactions was based on a combination of clinical interviews and physical and laboratory exams. Adverse reactions were defined in accordance with the Naranjo algorithm. RESULTS A total of 67.6% of all readmissions were related to adverse drug reactions, with tacrolimus accounting for 80% of the drug reactions. The most common cause of readmission was infection (48.6%), followed by procedure-related reasons (29.7%). Of all patients requiring admission, 39.1% had Model for End-stage Liver Disease (MELD) scores below 21 at the time of transplantation, 17.4% had MELD scores between 21 and 29, and 43.5% had MELD scores above 29. Most (66.7%) of those readmitted more than twice had MELD scores above 29. CONCLUSION Adverse drug reactions related to immunosuppressants frequently lead to readmission among liver transplant patients, and in our series tacrolimus was the most frequently associated drug.

Abstract
Recent genome-wide association studies have pointed to single-nucleotide polymorphisms (SNPs) in genes encoding the neuronal calcium channel CaV1.2 (CACNA1C; rs1006737) and the presynaptic active zone protein Piccolo (PCLO; rs2522833) as risk factors for affective disorders, particularly major depression. Previous neuroimaging studies of depression-related endophenotypes have highlighted the role of the subgenual cingulate cortex (CG25) in negative mood and depressive psychopathology. Here, we aimed to assess how recently associated PCLO and CACNA1C depression risk alleles jointly affect memory-related CG25 activity as an intermediate phenotype in clinically healthy humans. To investigate the combined effects of rs1006737 and rs2522833 on the CG25 response, we conducted three functional magnetic resonance imaging studies of episodic memory formation in three independent cohorts (N=79, 300, 113). An epistatic interaction of PCLO and CACNA1C risk alleles in CG25 during memory encoding was observed in all groups, with carriers of no risk allele and of both risk alleles showing higher CG25 activation during encoding when compared with carriers of only one risk allele. Moreover, PCLO risk allele carriers showed lower memory performance and reduced encoding-related hippocampal activation. In summary, our results point to region-specific epistatic effects of PCLO and CACNA1C risk variants in CG25, potentially related to episodic memory. Our data further suggest that genetic risk factors on the SNP level do not necessarily have additive effects but may show complex interactions. Such epistatic interactions might contribute to the 'missing heritability' of complex phenotypes.

Abstract
French law allows organ donation after death due to cardiocirculatory arrest. In the Maastricht classification, type III non-heart-beating donors are those who experience cardiocirculatory arrest after the withdrawal of life-sustaining treatments. French authorities in charge of regulating organ donation (Agence de la Biomédecine, ABM) are considering organ collection from Maastricht type III donors. We describe a scenario for Maastricht type III organ donation that fully complies with the ethical norms governing care to dying patients. That organ donation may occur after death should have no impact on the care given to the patient and family. The dead-donor rule must be followed scrupulously: the organ retrieval procedure must neither cause nor hasten death. The decision to withdraw life-sustaining treatments, withdrawal modalities, and care provided to the patient and family must adhere strictly to the requirements set forth in patient-rights legislation (the 2005 Léonetti law in France) and should not be influenced in any way by the possibility of organ donation. A major ethical issue regarding the family is how best to transition from discussing treatment-withdrawal decisions to discussing possible organ retrieval for donation should the patient die rapidly after treatment withdrawal. Close cooperation between the healthcare team and the organ retrieval team is crucial to minimize the distress of family members during this transition. Modalities for implementing Maastricht type III organ donation are discussed here, including the best location for withdrawing life-sustaining treatments (operating room or intensive care unit).

Abstract
Human Insulin-like growth factor 1 (hIGF-1) consists of 70 amino acids in a single chain with three intermolecular disulfide bridges possessing valuable therapeutic effects. To date, numerous variants of specifically engineered hIGF-1 have been produced so as to improve hIGF-1 biological activity, stability and stronger binding to IGF-1 receptor. Mecasermin is one of the modified variants with one amino acid substitution near the N-terminal (T4I) approved for the treatment of growth failure diabetes, wound healing, amyotrophic lateral sclerosis and severe primary IGF-1 deficiency. No scientific report for recombinant production of mecasermin in Escherichia coli (E. coli) expression system has been sofar reported. In the present study, we therefore investigated the overexpression of mecasermin in two different E. coli strains in order to obtain higher yield of recombinant protein. To achieve this goal, mecasermin DNA encoding sequence was designed based on polypeptide sequence, optimized according to E. coli codon preference, and cloned in pET15b. Recombinant vector, pET15-mecasermin, transferred into two E. coli strains rigami B (DE3) and BL21 (DE3) and induced for expression in a small scale. Results revealed the E. coli Origami B (DE3) expression system was a preferable host for mecasermin production due to its high expression level being around twice as much as BL21 (DE3). Large scale mecasermin production was performed in batch culture and produced recombinant protein specifically confirmed by western blotting and mass spectroscopy. Since major part of recombinant mecasermin was expressed as inclusion body, isolation and refolding was accomplished through developed purification procedure, and finally recombinant protein was successfully purified by gel filtration chromatography.

Abstract
BACKGROUND Intravenous (IV) and subcutaneous (SC) immunoglobulin (Ig) administration is a safe and an efficacious treatment in patients with IgG deficiency. Home administration of IV Ig and SC Ig has recently been approved in France. Most of the patients treated in hospital ask for home treatment. Some patients prefer monthly IV administration, others weekly SC administration. MATERIAL AND METHODS We evaluated in details the cost of both of these practices. We currently use electric pumps for both IV and SC administration which are fixed to the patient giving complete freedom and mobility. RESULTS For 20 g administrated per 4 week, the total cost of home treatment is 1,518 euro with SC Ig and 1,033 euro with IV Ig. For 40 g administrated per 4 week, the total cost of home treatment is 2,507 euro to 2,729 euro with SC Ig and 2,034 euro with IV Ig. The difference is mainly explained by the cost of renting the electric pumps and by the cost of furniture for SC administration. The choice of home Ig substitution must be given to all patient receiving treatment in hospital. CONCLUSIONS Home IV and home SC perfusions are two possible options each different with there own advantages and disadvantages. The cost of each procedure must be known by the medical staff.

Abstract
OBJECTIVE Recent studies have suggested that the definition of optimal cytoreduction for advanced EOC should be changed from the current Gynecologic Oncology Group threshold of < or =1 cm residual disease to no gross residual disease owing to improved survival of patients (pts) rendered macroscopically disease-free. The objective of this study was to analyze survival rates at very specific residual disease diameters to determine the optimal goal of primary cytoreduction for bulky stage IIIC EOC. METHODS A prospectively kept database was used to identify and review the records of all pts with Stage IIIC EOC who underwent primary cytoreductive surgery at our institution between January 1989 and December 2003. To analyze a homogeneous cohort of cases, we excluded pts with stage IIIC disease based on nodal metastasis alone (without bulky abdominal tumor), fallopian tube or primary peritoneal carcinomas, and borderline tumors. Standard statistical analyses were utilized. RESULTS The study cohort included 465 pts. The median age was 60 years (range, 25-87), and the median follow-up was 38 months (range, 1-199). Univariate and multivariate analyses, which included various prognostic factors, identified amount of residual disease as a significant prognostic factor (P < 0.001). Median overall survival in relation to the 5 residual disease categories was: no gross residual, 106 months; gross < or =0.5 cm, 66 months; 0.6-1.0 cm, 48 months; 1-2 cm, 33 months; >2 cm, 34 months. Statistical comparison between the 5 residual disease categories revealed 3 distinct groups with significantly different survival rates (P < 0.01). These 3 groups were: (1) no gross residual; (2) gross < or =1 cm residual; and (3) >1 cm residual. Although the difference in survival did not reach statistical significance, within the gross < or =1 cm residual group, there was a trend toward improved survival in pts left with smaller volume, < or =0.5 cm residual compared with those with 0.6-1.0 cm residual (P = 0.06). CONCLUSION Our data suggest that removal of all evidence of macroscopic disease is associated with prolonged survival and should be the goal of primary cytoreductive surgery. If complete gross resection is not feasible, however, cytoreduction to as minimal residual tumor as possible should be the focus of cytoreductive efforts, as each incremental decrease in residual disease below 1 cm may be associated with an incremental improvement in overall survival.

Abstract
Brain connections depend on a stable association between dendrites and axons whose cytoskeleton is stabilized by the proteins MAP-2 and tau, respectively. The glial protein S-100beta inhibits the phosphorylation by PKC of these two microtubule-associated proteins. In order to determine if exogenous S-100beta can directly influence the cytoskeleton of living cells, cultures of N-18 cells (neuroblastoma clonal cell line) are treated for 30 min in serum-free medium with 10(-6) M colchicine. In normal media, colchicine induces a rapid retraction of processes, membrane blebbing, nuclear collapse, and cell death. The observed cellular changes, due to cytoskeletal collapse after exposure to colchicine, are similar and consistent with the loss of processes and cytoplasmic blebbing seen in cells undergoing apoptosis. The addition of 20 ng/ml of S-100beta after the initial 30-min exposure to colchicine prevents apoptosis, nuclear collapse and induces the regrowth of retracted processes. Cells were treated with the Hoechst Stain, a fluorescent marker that binds to nuclear material, to determine the occurrence of apoptosis in our cultures. In our control cultures, receiving no drugs, we found that 15.1% of the cells were apoptotic. When colchicine was added to the culture medium we found that 31.6% of the cells became apoptotic. However, when colchicine was followed by exposure to S-100beta we found that only 5.4% of the cells were apoptotic. Our results suggest that extracellular application of the glial protein S-100beta is sufficient to reverse colchicine-induced cytoskeletal collapse and prevent the resultant apoptosis of the cells. The increased levels of S-100beta seen after brain injury and in certain neurological and psychiatric disorders may be considered as beneficial for brain recovery.

Abstract
In order to examine the reliability and validity of the SF-36 for use with individuals with TBI, the SF-36 and three measures of health-related problems in persons with TBI (BDI-II, TIRR Symptom Checklist, Health Problems List) were administered to 271 individuals without a disability, 98 individuals with mild TBI, and 228 individuals with moderate-severe TBI. Internal consistency (reliability) was demonstrated for all SF-36 scales. Significant correlations were found between the SF-36 scales and the other measures, with stronger correlations emerging in the TBI groups. The TBI groups obtained significantly lower SF-36 scores than the comparison group, and the mild TBI group scored lower than the moderate-severe group. For the most part, the differences between the TBI groups disappeared when BDI-II scores were controlled for. These findings suggest that the SF-36 is a reliable and valid measure for use with persons with TBI.

Abstract
Familial hypercholesterolemia by usual definition reflects mutations of the LDL-receptor gene. Extensive molecular characterization of mutations ascertained mainly through homozygotes (the Dallas collection) has been presented by Hobbs et al. (Hum Mutat 1:445-446, 1992). This paper catalogues a spectrum of 134 mutations (27 novel mutations in 45 patients, 24 previously described mutations in 89 patients) ascertained through heterozygotes from the analysis of 791 patients with definite, probable, or possible FH, mainly from the UK, using high-throughput modifications of the single-strand conformation polymorphism technique. From a composite database of LDL receptor gene mutations complied from these two sets and from the literature, deductions are made about ascertainment bias, mutation rates, and molecular heterogeneity. Calculations suggest that there may be a large number of rare amino acid variants in the general population not causing classic FH. Approaches to, and feasibility of, molecular diagnostics are considered.

Abstract
The objective of this study was to compare the utility of ICIDH-based models and needs-based models for predicting subjective quality of life in individuals with traumatic brain injury (TBI). Using an existing data base of individuals with TBI living in the community, seven predictive models were tested using multiple regression analyses. In comparing adjusted R2 associated with each of seven models, it was concluded that needs-based models using subjective indicators clearly predict more variance in measures of life satisfaction, or subjective well-being, than do either type of model relying on objective measures. It is suggested that, in documenting 'outcomes' of rehabilitation, the degree to which the focal individual's important needs are met defines more directly his/her well-being than do measures of impairment, disability or handicap.
