Abstract
BACKGROUND Prior trials validated triplet chemotherapy (Tri-CT) with bevacizumab as first line treatment for metastatic colorectal cancer (mCRC) but real-world data are scarce and practices remain heterogeneous. AIMS To evaluate Tri-CT +/- bevacizumab efficacy and safety, and to identify factors influencing treatment decisions. METHODS The COLOTRIP retrospective study enrolled mCRC patients treated from 2014 to 2019 in 14 French centers. RESULTS Of 299 patients (81% PS 0-1, 58% RAS-mutated and 19% BRAF-mutated), 51% received Tri-CT and 49% Tri-CT + bevacizumab. Metastatic disease was classified as resectable (6.5%), potentially resectable (40%), and unresectable (54%). Bevacizumab use was associated with primary tumor location, mutational status and number of metastases. Median overall survival was 33.5 months in the Tri-CT group and 23.9 months in the Tri-CT + bevacizumab group, with median progression-free survival being 14.5 and 11.4 months. After adjusting for initial characteristics, no difference in survival was noted. Around 30% of patients experienced grade ≥3 adverse events. CONCLUSIONS This study highlights several factors influencing Tri-CT use +/- bevacizumab decision and confirms the real-world good oncological outcomes and tolerability of these regimens in mCRC patients. Our results suggest that Tri-CT alone may by an appropriate option for specific subgroups of patients.

Abstract
BACKGROUND AND AIMS Craving is central in the definition of addictive disorders because of its diagnostic and prognostic value. Its measurement is essential in clinical practice. Previous reviews provided a better overview of existing instruments; however, they do not consider emerging substances and behaviors such as sexual addictions. Our objectives were threefold: (1) to provide a systematic review of craving assessment instruments and their psychometric characteristics within a transdiagnostic approach, (2) to highlight and map their conceptual relationships and (3) to identify potential sexual craving assessment instruments. METHODS The review was conducted using Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) methodology. The PubMed, Embase, PsychInfo and Cochrane/Central databases were searched for publications that met the following inclusion criterion: validation studies of craving assessment instruments, regardless of target substance or behavior. The original search identified 4561 references and included 147 articles. Each selected study was a peer-reviewed publication. RESULTS This review provides a synthesis of the psychometric properties of 36 original instruments and identified 93 variations of these instruments (e.g. translations). We were able to highlight five transdiagnostic families of instruments, each corresponding to a conceptual model. Only one instrument for assessing craving in the domain of compulsive sexual behavior, focused on pornography use, has been identified: the Pornography Craving Questionnaire. CONCLUSION This review mapped all craving assessment instruments from a transdiagnostic perspective, finding 36 original instruments and 93 variations. The evolution of instruments to measure craving mirrors the evolution of the concept of craving which has progressively integrated cognitive, conditioning and sensory dimensions, and attests to the importance of the context of assessment. Development of an instrument to measure 'sexual craving' is needed and could be based on the data from our review.

Abstract
Inferring causal effects between variables when utilizing observational data is challenging due to confounding factors not controlled through a randomized experiment. Propensity score matching can decrease confounding in observational studies and offers insights about potential causal effects of prophylactic management interventions such as vaccinations. The objective of this study was to determine potential causality and impact of vaccination with an Escherichia coli J5 bacterin on the productive performance of dairy cows applying propensity score matching techniques to farm-recorded (e.g., observational) data. Traits of interest included 305-d milk yield (MY305), 305-d fat yield (FY305), 305-d protein yield (PY305), and somatic cell score (SCS). Records from 6,418 lactations generated by 5,121 animals were available for the analysis. Vaccination status of each animal was obtained from producer-recorded information. Confounding variables considered were herd-year-season groups (56 levels), parity (5 levels: 1, 2, 3, 4, and ≥5), and genetic quartile groups (4 levels: top 25% through bottom 25%) derived from genetic predictions for MY305, FY305, PY305, and SCS, as well as for the genetic susceptibility to mastitis. A logistic regression model was applied to estimate the propensity score (PS) for each cow. Subsequently, PS values were used to form pairs of animals (1 vaccinated with 1 unvaccinated control), depending on their PS similarities (difference in PS values of cows within a match required to be <20% of 1 standard deviation of the logit of PS). After the matching process, 2,091 pairs of animals (4,182 records) remained available to infer the causal effects of vaccinating dairy cows with the E. coli J5 bacterin. Causal effects estimation was performed using 2 approaches: simple matching and a bias-corrected matching. According to the PS methodology, causal effects of vaccinating dairy cows with a J5 bacterin on their productive performance were identified for MY305. The simple matched estimator suggested that vaccinated cows produced 163.89 kg more milk over an entire lactation when compared with nonvaccinated counterparts, whereas the bias-corrected estimator suggested that such increment in milk production was of 150.48 kg. Conversely, no causal effects of immunizing dairy cows with a J5 bacterin were identified for FY305, PY305, or SCS. In conclusion, the utilization of PS matching techniques applied to farm-recorded data was feasible and allowed us to identify that vaccination with an E. coli J5 bacterin relates to an overall milk production increment without compromising milk quality.

Abstract
Fleas are ectoparasites affecting many animal species but reports in captive nonhuman primates are rare and mainly concern pet monkeys. Moreover, to the authors' knowledge, a detailed report on marmosets is not known at present. This case describes the clinical signs, diagnosis, treatment and follow-up of a flea infestation by Ctenocephalides felis in a captive colony of common marmosets. Fleas, flea feces and skin lesions were identified on two animals during annual health screening. Subsequently, the entire colony was examined, and nearly half of the colony showed signs of infestation. Consequently, treatment was initiated for the entire colony and the environment. Animals received two topical administrations of imidacloprid (5 mg for animals <200 g and 10 mg for animals weighing >200 g) three weeks apart, and their enclosures were decontaminated using vaporizers containing permethrin, piperonyl butoxide, and pyriproxyfen. Subsequently, skin lesions were resolved and no evidence of fleas were noticed. No side effects of the treatment were observed. Stray cats were identified as the source of the infestation. Their access to the animal-related rooms was stopped. No reinfestation has been reported for 3 years. The topical application of imidacloprid appeared effective with no adverse events occurring, so may be appropriate for use in other non-human primates.

Abstract
BACKGROUND The COVID-19 pandemic caused major oncology care pathway disruption. The CAPANCOVID study aimed to evaluate the impact on pancreatic adenocarcinoma (PA) - from diagnosis to treatment - of the reorganisation of the health care system during the first lockdown. METHODS This multicentre ambispective observational study included 833 patients diagnosed with PA between September 1, 2019 and October 31, 2020 from 13 French centres. Data were compared over three periods defined as before the outbreak of COVID-19, during the first lockdown (March 1 to May 11, 2020) and after lockdown. RESULTS During the lockdown, mean weekly number of new cases decreased compared with that of pre-pandemic levels (13.2 vs. 10.8, -18.2%; p = 0.63) without rebound in the post-lockdown period (13.2 vs. 12.9, -1.7%; p = 0.97). The number of borderline tumours increased (13.6%-21.7%), whereas the rate of metastatic diseases rate dropped (47.1%-40.3%) (p = 0.046). Time-to-diagnosis and -treatment were not different over periods. Waiting neoadjuvant chemotherapy in resectable tumours was significantly favoured (24.7%-32.6%) compared with upfront surgery (13%-7.8%) (p = 0.013). The use of mFOLFIRINOX preoperative chemotherapy regimen decreased (84.9%-69%; p = 0.044). After lockdown, the number of borderline tumours decreased (21.7%-9.6%) and advanced diseases increased (59.7%-69.8%) (p = 0.046). SARS-CoV-2 infected 39 patients (4.7%) causing 5 deaths (12.8%). CONCLUSION This cohort study suggests the existence of missing diagnoses and of a shift in disease stage at diagnosis from resectable to advanced diseases with related therapeutic modifications whose prognostic consequences will be known after the planned follow-up.

Abstract
Deficient mismatch repair system (dMMR)/microsatellite instability (MSI) is found in about 5% of metastatic colorectal cancers (mCRCs) with a major therapeutic impact for immune checkpoint inhibitor (ICI) use. We conducted a multicentre study including all consecutive patients with a dMMR/MSI mCRC. MSI status was determined using the Pentaplex panel and expression of the four MMR proteins was evaluated by immunohistochemistry (IHC). The primary endpoint was the rate of discordance of dMMR/MSI status between primary tumours and paired metastases. We included 99 patients with a dMMR/MSI primary CRC and 117 paired metastases. Only four discrepancies (3.4%) with a dMMR/MSI primary CRC and a pMMR/MSS metastasis were initially identified and reviewed by expert pathologists and molecular biologists. Two cases were false discrepancies due to human or technical errors. One discordant case could not be confirmed due to the low level of tumour cells. The last case had a confirmed discrepancy with a dMMR/MSI primary CRC and a pMMR/MSS peritoneal metastasis. Our study demonstrated a high concordance rate of dMMR/MSI status between primary CRCs and their metastases. The analysis of one sample, either from the primary tumour or metastasis, with consistent dMMR and MSI status seems to be sufficient prior to treatment with ICI.

Abstract
Determination of microsatellite instability (MSI) using molecular test and deficient mismatch repair (dMMR) using immunohistochemistry (IHC) has major implications on colorectal cancer (CRC) management. The HSP110 T17 microsatellite has been reported to be more monomorphic than the common markers used for MSI determination. Large deletion of HSP110 T17 has been associated with efficacy of adjuvant chemotherapy in dMMR/MSI CRCs. The aim of this study was to evaluate the interest of HSP110 deletion/expression as a diagnostic tool of dMMR/MSI CRCs and a predictive tool of adjuvant chemotherapy efficacy. All patients with MSI CRC classified by molecular testing were included in this multicenter prospective cohort (n = 381). IHC of the 4 MMR proteins was carried out. HSP110 expression was carried out by IHC (n = 343), and the size of HSP110 T17 deletion was determined by PCR (n = 327). In the 293 MSI CRCs with both tests, a strong correlation was found between the expression of HSP110 protein and the size of HSP110 T17 deletion. Only 5.8% of MSI CRCs had no HSP110 T17 deletion (n = 19/327). HSP110 T17 deletion helped to re-classify 4 of the 9 pMMR/MSI discordance cases as pMMR/MSS cases. We did not observe any correlation between HSP110 expression or HSP110 T17 deletion size with time to recurrence in patients with stage II and III CRC, treated with or without adjuvant chemotherapy. HSP110 is neither a robust prognosis marker nor a predictor tool of adjuvant chemotherapy efficacy in dMMR/MSI CRC. However, HSP110 T17 is an interesting marker, which may be combined with the other pentaplex markers to identify discordant cases between MMR IHC and MSI.

Abstract
Since lack of empathy is an important indicator of violent behaviors, researchers need consistent and valid measures. This study evaluated the practical significance of a potential physiological correlate of empathy compared to a traditional self-report questionnaire in 18 male violent offenders and 21 general population controls. Empathy skills were assessed with the Interpersonal Reactivity Index (IRI) questionnaire. Heart-Rate Variability (HRV) was assessed with an electrocardiogram. The RMSSD (Root Mean Square of the Successive beat-to-beat Differences), an HRV index implicated in social cognition, was calculated. There were no group differences in IRI scores. However, RMSSD was lower in the offender group. Positive correlations between RMSSD and IRI subscales were found for controls only. We conclude that psychometric measures of empathy do not discriminate incarcerated violent offenders, and that the incorporation of psychophysiological measures, such as HRV, could be an avenue for forensic research on empathy to establish translatable evidence-based information.

Abstract
4036 Background: Regorafenib (R) and trifluridine/tipiracil (T) have proved their efficacy in patients (pts) with metastatic colorectal cancer (mCRC) refractory to standard chemotherapy and targeted therapies. However, it remains unclear which drug should be administered first. Methods: This observational study was prospectively conducted in 13 centers between 6/2017 and 9/2019 in France. All consecutive pts with chemoresistant mCRC and receiving T and/or R were eligible. The aim of this study was to describe efficacy and tolerability of T and/or R. Overall survival (OS) and progression-free survival (PFS) of pts receiving T then R (T/R) and the opposite sequence (R/T) were also assessed. Results: A total of 237 pts (25% R and 75% T) were enrolled (109 male, median age: 67 years (32-91), mean previous lines of treatment: 2.5 (1-7)). Baseline ECOG PS was 0-1 in 77% of pts. As compared to R pts, T pts were significantly older (68 years vs 63; p = 0.033) and with > 3 metastatic sites (44% vs 30%, p = 0.018). Median OS were 6.6 and 6.2. months in the T and R group, respectively (NS). Median PFS were 2.4 and 2.1 months in the T and R group, respectively (NS). After matching 46 paired pts according to primary tumor resection, age and number of metastatic sites, a trend to a longer OS (9.5 vs 6.8 months; p = 0.17) and a significantly longer PFS (2.8 vs 2 months; p = 0.048) were observed in the T group. Among the overall population, 24% of pts received R/T or T/R sequence. Median OS from first treatment were 10.7 months in the R/T group and 9.8 months in the T/R (NS). Treatment sequence was not an independent prognostic factor for OS or PFS in multivariable analysis. Tolerability profiles were similar to previously published data, but dose reductions were more frequent in the R group (44 vs 27%, p = 0.008). Conclusions: Efficacy and safety results in this real life prospective study are in line with those published phase III trials. Both treatments seem similar in term of efficacy favoring T for clinical use as shown by the higher number of patients receiving this drug.

Abstract
BACKGROUND Although no data have been reported beyond second-line therapy, aflibercept is approved in this setting in many countries. We conducted a multicenter study to analyze the efficacy and safety of a aflibercept-chemotherapy regimen beyond second-line therapy in patients with metastatic colorectal cancer. PATIENTS AND METHODS Metastatic colorectal cancer patients treated with aflibercept beyond second-line therapy were included. Objective response rate, overall survival (OS), and progression-free survival (PFS) were assessed. RESULTS A total of 130 patients were included. Median OS and PFS were 7.6 months (95% confidence interval, 6.2-9.3) and 3.3 months (95% confidence interval, 2.7-3.8), respectively. The best response rates were partial response 6.9%, stable disease 38.5%, progressive disease 42.5%, and not evaluable 12%. According to whether patients received previous FOLFIRI (leucovorin, 5-fluorouracil, irinotecan, and oxaliplatin)-bevacizumab or not, OS was 7.7 and 8.1 months (P = .31), and PFS was 2.9 and 3.9 months (P = .02), respectively. Interestingly, PFS and OS were both significantly improved by 4% and 5% per month, respectively, without antiangiogenic treatment before the initiation of the aflibercept regimen. The negative effect of prior FOLFIRI-bevacizumab or shorter time since last bevacizumab was maintained in multivariate analysis for both OS and PFS. CONCLUSION The aflibercept-chemotherapy regimen is a therapeutic option in patients with chemorefractory disease beyond second-line therapy, in particular in patients with an antiangiogenic-free interval.

Abstract
AIM Impulsive behaviours, which are frequent in young people suffering from psychosis have been linked to risky and violent behaviours and participate to the burden of psychotic illness. Given that morphological brain correlates of impulsivity in schizophrenia have been poorly investigated especially in young adults, the aim of this study was to investigate the relationship between impulsivity and cortical thickness in early psychosis (EP) patients. METHOD A total of 17 male subjects in the early phase of psychosis were recruited. Impulsivity was assessed with the Lecrubier Impulsivity Rating Scale. Mean cortical thickness was extracted from magnetic resonance imaging brain scans, using surface-based methods. RESULTS Mean cortical thickness in the frontal lobe correlated positively with mean impulsivity in EP male patients. CONCLUSION Our results suggest that psychotic subjects exhibiting higher impulsivity have larger frontal cortical thickness, which may pave the way towards the identification of patients with a higher risk to display impulsive behaviours.

Abstract
Various neuroscientific techniques are increasingly being used in criminal courts causing a vivid debate on the way that this kind of techniques will and should be used as scientific evidence. The role of experts in this context is important, since it is them that analyse, present, interpret and communicate the results of these techniques to the judges and the jury. In an attempt to contribute to the discussion about the role of the experts in criminal cases where neuroimaging evidence was introduced, we examined twenty seven cases from the US and Europe. Focusing on the role of experts and their presentation of neuroscientific evidence, we aimed to examine the extent to which neuroimaging data can contribute to the construction of a solid and more objective, "scientifically - based" case. We found that neurobiological information introduced through experts' testimony is generally used in order to demonstrate some physical, organic base of a psychiatric condition, or/and in order to make visible some brain lesion, (structural or functional), susceptible to have affected the capacity to reason and to control one's impulses. While neuroimaging evidence is often presented by the defence as a scientific method able to offer a precise diagnosis of the pathology in question, our case analysis shows that the very same neurobiological evidence can be interpreted in different - sometimes diametrically opposed - ways by defence and State experts. Conflicting testimony about the same empirical evidence goes against the hypothesis of neuroscientific techniques constituting "objective and hard evidence", able to reach solid, scientific and objective conclusions. Frequent conflicts between neuroimaging experts require the courts to deal with the resulting uncertainty. As the law changes with technology, it is necessary for legal professionals to train and be prepared for the new issues they may encounter in light of new developments in neuroscience, so that they become more vigilant as to the interpretation of neuroscientific data.

Abstract
Violence in correctional facilities is an important issue for both prisoners and prison staff. Risk assessment instruments have demonstrated their accuracy in predicting the risk of (re) offending and institutional violence in psychiatric settings, but less is known about their ability to predict violent misconduct in prison. The present study applied four risk assessment instruments (Structured Assessment of Protective Factors for violence risk, Historical Clinical Risk Management-20, Psychopathy checklist - Revised, and Violent Risk Appraisal Guide) to 52 violent offenders in a Swiss prison in order to evaluate the instruments' predictive validities. Outcomes were instances of physically violent, other and any misconduct as recorded in prison files during the 12 months following the prisoners' assessments. Approximately 15% of offenders committed physically violent misconduct and approximately 42% committed any misconduct. The results show that mainly dynamic assessment tools are as good predictors of physically violent misconduct as mainly static assessment tools. Targeting dynamic factors could increase the effectiveness of interventions to reduce the risk of physical violence in prison.

Abstract
OBJECTIVE This study aims to determine whether it is possible to identify clinical profiles at risk of violent behaviors (VB) in the early phase of psychotic disorders, on the basis of the main dynamic psychopathological risk factors and describe characteristics of the groups with highest levels of violent behaviors. METHOD A total of 265 patients, aged 18 to 35, treated at the Treatment and early Intervention in Psychosis Program (TIPP-Lausanne), a specialized early psychosis program, were included in this study. We conducted a latent-class analysis and a discriminative analysis on the basis of the main dynamic VB risk factors: substance use disorder, impulsivity, positive symptoms, insight, aggression, hostility, anger, emotional instability and adherence to treatment. These factors were evaluated by specialized scales and on the basis of the Positive and Negative Syndrome Scale (PANSS). VB were restricted to physical aggression against people, defined as "serious violence". They were assessed on the basis of a questionnaire listing violent offenses (Swiss Criminal Code) and VB such as assault and battery, information through the forensic psychiatric services and on the basis of the Staff Observation Aggression Scale (SOAS-R scale) during inpatient treatment phase. RESULTS Four heterogeneous subgroups were identified with respect to the studied clinical characteristics, including two groups with high rates of VB. The first group, comprising 46% of patients with VB, is distinguished by the prevalence of a range of dimensions related to hostility, impulsivity and emotional instability, associated with high levels of substance abuse and positive symptoms. These clinical dimensions are very significant at the statistical level, since they explain 70% of the construction of subgroups (discriminant analysis). The second group with 37% of patients with VB, is characterized by a lack of insight, lack of adherence to treatment and substance use. These two clinical profiles could increase the impairment of cognitive, functional and relational abilities and contribute to the development of VB in this early phase of psychosis. The third subgroup, with a violent behaviors rate of 28.6%, is distinguished by its high proportion of diagnoses of substance abuse (100%) and women (54%). A last subgroup of patients, the largest quantitatively, has a low proportion of VB (15%) and the lowest levels on the studied factors, suggesting that the majority of patients with this profile commit few VB. CONCLUSION Our results show that it is possible to identify groups at risk of violent behaviors during the early phase of psychosis on the basis of clinical characteristics that may evolve and therefore be the focus of preventive care. These results highlight the need to target substance use, impulsivity and lack of insight at follow-up in order to prevent VB.

Abstract
The linear dimensions and inertial characteristics of the body are important in locomotion and they change considerably during the ontogeny of animals, including humans. This longitudinal and ontogenetic study has produced the largest dataset to date of segmental morphometrics in a Catarrhini species, the olive baboon. The objectives of the study were to quantify the changes in body linear and inertial dimensions and to explore their (theoretical) mechanical significance for locomotion. We took full-body measurements of captive individuals at regular intervals. Altogether, 14 females and 16 males were followed over a 7-year period, i.e. from infancy to adulthood. Our results show that individual patterns of growth are very consistent and follow the general growth pattern previously described in olive baboons. Furthermore, we obtained similar growth curve structures for segment lengths and masses, although the respective time scales were slightly different. The most significant changes in body morphometrics occurred during the first 2 years of life and concerned the distal parts of the body. Females and males were similar in size and shape at birth. The rate and duration of growth produced substantial size-related differences throughout ontogeny, while body shapes remained very similar between the sexes. We also observed significant age-related variations in limb composition, with a proximal shift of the centre of mass within the limbs, mainly due to changes in mass distribution and in the length of distal segments. Finally, we observed what we hypothesize to be 'early biomechanical optimization' of the limbs for quadrupedal walking. This is due to a high degree of convergence between the limbs' natural pendular periods in infants, which may facilitate the onset of quadrupedal walking. Furthermore, the mechanical significance of the morphological changes observed in growing baboons may be related to changing functional demands with the onset of autonomous (quadrupedal) locomotion. From a wider perspective, these data provide unique insights into questions surrounding both the processes of locomotor development in primates and how these processes might evolve.

Abstract
3536 Background: Deficient Mismatch Repair (dMMR) in colorectal cancers (CRC) represent 12% of all tumors. In non-metastatic CRC setting, dMMR are associated with good prognosis but also with resistance to adjuvant 5-FU chemotherapy. In metastatic CRC (mCRC) setting, dMMR is found in less than 5% and its influence on prognosis and treatment response is little known. Methods: This multicenter retrospective study included all consecutive patients with dMMR mCRC treated between 2005 and 2015 in 17 centers. The Kaplan-Meier method was used to calculate overall survival (OS) and progression-free survival (PFS). Prognostic variables were evaluated in univariate analysis using the Log rank test and in multivariate analysis using the Cox regression model. Results: A total of 198 patients with dMMR mCRC were included (median age 64.6 years). dMMR mCRC were mostly diagnosed with synchronous metastases (59%) and frequent peritoneal carcinosis (43%). Lynch syndrome was found in 34% of cases and 36% of tumors had a BRAFV600E mutation. Median OS was 20.6 months. A low risk Kohne's prognostic index (HR = 0.40 [0.22-0.72], p = 0.02) and absence of peritoneal carcinosis (HR = 0.51 [0.29-0.90], p = 0.02) were associated with better OS in multivariate analysis. Main first-line regimens were 5FU-based (n = 20), oxaliplatin-based (n = 75) or irinotecan-based (n = 46) chemotherapy. Median PFS on first-line treatment was 5.9 months. The objective response rate (ORR) was 0%, 19% and 36% for 5FU-based, oxaliplatin-based and irinotecan-based chemotherapies, respectively (p = 0.02). A trend for a longer PFS (3.3, 5.5 and 10.2 months, respectively, p = 0.06) and OS (17.7, 21.1 and 34.2 months, respectively, p = 0.05) was also observed for irinotecan-based chemotherapy. The addition of bevacizumab to chemotherapy was associated with a significant increase of ORR (p = 0.01) and PFS (p = 0.04) as compared to the addition of an anti-EGFR therapy. Conclusions: This study suggests that dMMR mCRC are associated with poor prognosis and chemoresistance, especially to 5FU-based chemotherapy. Efficacy of irinotecan and bevacizumab should be evaluated in a prospective trial in combination with immune checkpoint inhibitors.

Abstract
Bluetongue virus (BTV) is an insect vector transmitted virus which causes an economically important disease in ruminants. BTV infection during pregnancy can result in infection of the foetus, which may lead to the birth of persistently infected or immunotolerant offspring. Since persistently infected animals continuously produce large amounts of virus they could be a source of infection for the insect vector. This could significantly influence the epidemiology of the virus and hence might require additional measures to control a BTV outbreak. Therefore, we investigated the potential of BTV-8 to induce persistent infection or immunotolerance in lambs in an experimental setting. Infection of eighteen 70-75 days pregnant ewes with wild type BTV-8 led to the birth of 25 out of 44 BTV RNA positive lambs (foetal infected, FI). All 23 FI lambs born alive also had anti BTV antibodies at birth; infectious virus could be recovered from 5 out of 25 FI lambs. Viral RNA loads decreased rapidly after birth; 19 out of 20 FI lambs that remained in the experiment until week 14 after birth, were RNA negative at that time. Since persistence of BTV-8 infection could not be demonstrated, we investigated whether foetal infection had an effect on protection against a field virus infection and on efficacy of vaccination. To this end, 5 FI lambs and 5 foetal non-infected (FNI) lambs were vaccinated with the inactivated Bovilis(®) BTV-8 vaccine, five months after birth. Three weeks after the vaccination, all lambs were infected with wild type BTV-8. The foetal infection did not interfere with vaccination efficacy. In contrast, foetal BTV-8 infection induced an immune response which afforded protection against BTV challenge comparable to the level of protection induced by vaccination.

Abstract
The legislatives evolutions imply an important recourse to the psychiatric expertise in order to evaluate the potential dangerousness of a subject. However, in spite of the development of techniques and tools for this evaluation, the dangerousness assessment of a subject is in practice extremely complex and discussed in the scientific literature. The evolution of the concept of dangerousness to the risk assessment involved a technicisation of this evaluation which should not make forget the limits of these tools and the need for restoring the subject, the meaning and the clinic in this evaluation.

Abstract
Bluetongue (BT) is an economically important disease of ruminants caused by bluetongue virus (BTV) and transmitted by Culicoides biting midges. The most practical and effective way to protect susceptible animals against BTV is by vaccination. Data from challenge studies in calves and sheep conducted by Intervet International b.v., in particular, presence of viral RNA in the blood of challenged animals, were used to estimate vaccine efficacy. The results of the challenge studies for calves indicated that vaccination is likely to reduce the basic reproduction number (R(0)) for BTV in cattle to below one (i.e. prevent major outbreaks within a holding) and that this reduction is robust to uncertainty in the model parameters. Sensitivity analysis showed that the whether or not vaccination is predicted to reduce R(0) to below one depended on the following assumptions: (i) whether "doubtful" results from the challenge studies are treated as negative or positive; (ii) whether or not the probability of transmission from host to vector is reduced by vaccination; and (iii) whether the extrinsic incubation period follows a realistic gamma distribution or the more commonly used exponential distribution. For sheep, all but one of the vaccinated animals were protected and, consequently, vaccination will consistently reduce R(0) in sheep to below one. Using a stochastic spatial model for the spread of BTV in Great Britain (GB), vaccination was predicted to reduce both the incidence of disease and spatial spread in simulated BTV outbreaks in GB, in both reactive vaccination strategies and when an incursion occurred into a previously vaccinated population.

The induction of tumor-specific immune responses is largely dependent on the ability of dendritic cells (DCs) to present tumor-associated antigens to T lymphocytes. Therefore, we investigated the use of DC-associated promoter-driven genetic vaccines to specifically target DC in vivo. Restricted expression of vaccine-encoding genes in DC should enhance specificity and improves their safety for clinical applications. Hereto, 3-5 kb upstream sequences of the murine genes encoding CD11c, DC-SIGN, DC-STAMP and Langerin were isolated, characterized and subcloned into enhanced green fluorescent protein (EGFP) reporter constructs. Upon electroporation, EGFP was expressed in DC cell lines, but not in other cell lines, confirming DC-restricted promoter activity. When these promoters were cloned into a construct upstream of the gene for ovalbumin (OVA), it appeared that DC-STAMP promoter-driven expression of OVA (pDCSTAMP/OVA) in DC yielded the most efficient OVA-specific CD4+ and CD8+ T-cell responses in vitro. Administration of pDC-STAMP/OVA in vivo, using the tattoo gun vaccination system, evoked specific immune responses as evidenced in a mouse tumor model. Adoptively transferred pDC-STAMP/OVA-transfected DCs induced strong CD8+ T-cell proliferation in vivo. These experiments demonstrate that our DC-directed promoter constructs are potential tools to restrict antigen expression in DC and could be implemented to modulate DC function by the introduction of relevant proteins.

Abstract
The effect of vaccination with a commercial inactivated Bluetongue virus serotype 8 (BTV-8) vaccine on the ability of BTV-8 to cross the ruminant placenta was investigated in two experiments. Ten pregnant ewes (Experiment 1) or heifers (Experiment 2) were vaccinated according to the manufacturer's instructions. Three weeks after the completion of the vaccination schedule, all vaccinated animals were infected with BTV-8 together with ten non-vaccinated pregnant animals that served as challenged controls. Four additional pregnant animals received a mock challenge at the same time point. Three weeks after the challenge, the foetuses were collected. In the sheep experiment, the lambs of the vaccinated ewes and the mock infected ewes were negative in the virus isolation, whereas BTV-8 could be isolated from 11/23 lambs of 6/10 ewes in the BTV-8 challenged control group. The incidence and severity of BTV associated lesions, such as haemorrhages, meningitis/encephalitis and necrosis in the placentomes was significantly higher in the BTV-8 challenged control group. The rate of transplacental transmission was less in the cattle experiment: BTV-8 could be detected in 2/10 calves in the BTV-8 challenged control group. All other calves were negative. Vaccination clearly reduced transplacental transmission of BTV-8 in the sheep experiment, whereas in the cattle experiment, the incidence of transmission was too low to demonstrate a significant reduction of transmission by vaccination. However, the vaccine very effectively blocked viraemia, which suggests that the vaccine might prevent transmission in cattle as well. Transplacental transmission of BTV has serious economical consequences, due to the loss of progeny to the livestock industry. Vaccination can be an important aid in the reduction of these economic losses.

Abstract
ABSTRACTThe experimental investigation and modelling of radionuclides sorption processes is an essential part of safety analyses of an underground repository of radioactive wastes in geological formations. Physico—chemical phenomena at oxide/solution interfaces have been studied in the case of the system constituted by amorphous silica and americium (III) in the presence of humic substances as organic complexing agents. The retention behaviour of Am(III) onto silica appears dependent on pH, ionic strength and in particular humic concentration. At a ionic strength of 0.1 M, the presence of low concentration of humic acids (1 mg/l) enhances the Am(III) retention in the pH range 3-5.5, whereas at higher pH, its uptake is largely decreased. At lower ionic strength (0.001 M), Am(III) retention on silica is highly lowered, in the pH range 3-7 in the presence of humic acids. Reversibility experiments show the desorption of americium in the absence of humic substances, and also the desorption of the humics on the silica with respect of the pH. The surface complexation model has been applied to our results in the different systems and apparent surface complexation constants have been determined.

Abstract
Bluetongue serotype 8 has become a major animal health issue in the European Union and the European member States have agreed on a vaccination strategy, which involves only inactivated vaccines. In this study, the efficacy of two inactivated vaccines against bluetongue virus serotype 8 (BTV-8) used in Europe since 2008, BTVPUR ALSAP(®) 8 (MERIAL) and BOVILIS(®) BTV8 (Intervet/SP-AH), was evaluated in goats immunized and challenged with BTV-8 field isolates under experimental conditions. Serological, virological and clinical examinations were conducted before and after challenge. Three groups of 10 goats each (groups A, B and C) were randomly constituted and 2 groups (A and C) were subcutaneously vaccinated twice with one dose of the two commercial vaccines BTVPUR ALSAP 8 (group A) or BOVILIS BTV8 (group C) respectively. Animals of the groups A, C and B (B: controls) were challenged with a virulent inoculum containing BTV-8. During the experiment, it was found out that the BTV-8 challenge inoculum was contaminated with another BTV serotype. However, results demonstrated that vaccination of goats with two injections of BTVPUR ALSAP 8 or BOVILIS BTV8 provided a significant clinical protection against a BTV-8 challenge and completely prevented BTV-8 viraemia in all vaccinated animals. Qualitative data showed no difference in the kinetics and levels of the humoral response induced by these two inactivated vaccines.

Abstract
The ability of Bluetongue virus serotype 8 (BTV-8) originating from the 2006 European outbreak to cross the ovine placenta during early and mid gestation was investigated in two separate experiments. In the first experiment, 16 ewes were infected with BTV-8 at 70-75 days gestation. The foetuses were collected at 18-19 days after infection (dpi). BTV-8 could be isolated from at least two organs of 19 out of 40 lambs and from 11 out of 16 infected ewes. In the second experiment, 20 BTV-8 infected ewes in early gestation (day 40-45) were euthanized at 10 days (10 ewes) or 30 days (10 ewes) after infection. The presence of BTV could be demonstrated in two foetuses from two ewes at 10 dpi and in 4 foetuses from four ewes at 30 dpi. The main pathological findings in the foetuses in mid gestation were meningo-encephalitis and vacuolation of the cerebrum. In the foetuses early at gestation, haemorrhages in various foetal tissues and necrosis and haemorrhages in the placentomes were found. These experiments demonstrate for the first time the presence of infectious BTV in lamb foetuses at different stages of gestation, combined with a difference in transmission rate depending on the gestation stage. The high transmission rate found at mid term gestation (69%) makes our model very suitable for further research into the mechanisms of transplacental transmission and for research into the reduction of this route of transmission through vaccination.

Abstract
BACKGROUND Small-bowel adenocarcinoma (SBA) is a rare tumor of poor prognosis. Data on the efficacy of chemotherapy for advanced SBA are scarce. PATIENTS AND METHODS All patients with advanced SBA who received frontline chemotherapy from 1996 to 2008 were eligible for this retrospective multicenter study. RESULTS Ninety-three consecutive patients were included. In the entire population, the median progression-free survival (PFS) and overall survival (OS) times were 6.6 and 15.1 months, respectively. Median PFS times among patients treated with LV5FU2 (n = 10), FOLFOX (n = 48), FOLFIRI (n = 19) and LV5FU2-cisplatin (n = 16) were 7.7, 6.9, 6.0 and 4.8 months, respectively, while median OS times were 13.5, 17.8, 10.6 and 9.3 months, respectively. In multivariate analysis, World Health Organization performance status (PS) (P < 0.0001) and elevated serum levels of carcinoembryonic antigen (CEA) (P = 0.02) and carbohydrate antigen 19-9 (CA 19-9) (P = 0.03) were the only variables significantly associated with poor OS. In the subgroup of patients treated with platinum-based chemotherapy, multivariate analysis showed that LV5FU2-cisplatin was associated with poorer PFS (P < 0.0001) and OS (P = 0.02) compared with FOLFOX. CONCLUSIONS This is the largest study of chemotherapy in advanced SBA. Baseline PS and CEA and CA 19-9 levels were the main prognostic factors. FOLFOX seems to be the most effective platinum-based chemotherapy regimen.

Abstract
Speciation determination is of prime importance to explain and evaluate the mobility, the toxicity and the risk resulting from the presence of trace elements in natural systems, in particular in the case of radionuclides, in the framework of environment and waste management purposes. The present paper will then focus more specifically on the physico-chemical speciation of radionuclides, and more particularly of actinides, in the environment, with emphasis on the behavior in solution: from a chemical point of view (with important ligands including colloidal phases) using experimental data and speciation calculations, as well as from a more technical point of view (with analytical methods forin situspeciation determination and thermodynamic data determination). A review of recent papers (mainly from CEA) is presented.

Abstract
SummaryPurified humic acid has been covalently bound on activated epoxy silica gel particles. Determination of physical properties and chemical properties was conducted in order to characterize the material at different stages of the preparation. FTIR spectra and the PEC of the surface bound humic acid is very similar to that of humic acid starting material. This shows that the humic acid was not deteriorated during the surface binding process. This humic gel can be used as an analogue for sediment associated humic acid, with the advantage that covalently bound humic acid does not desorb, and thus allows for simple species separation between non-complexed and humic bound metal ions in batch and column experiments.

Abstract
Summary
The influence of humic acids (HA) on the retention of thorium (IV) onto the surface of silica colloids is investigated. Thorium is considered as an analogue of tetravalent actinides (U, Np, Pu), except for the fact that it has no f electrons. Silica (SiO2) is chosen as a model surface because it is a component of many minerals and because of its weak HA sorption properties. Retention experiments are performed by batch procedure at constant ionic strength (I = 0.1M NaClO4), at various pH (2 to 9) and HA concentrations (1–100mg/L). The sorption of Th(IV) onto colloidal amorphous silica is characterised using a surface complexation model. The ternary system (i.e. HA-Th-Silica) clearly shows the influence of HA on Th(IV) retention. This can lead to a strong reduction of the amount of Th(IV) sorbed onto silica in the presence of HA compared to silica colloids without HA, due to a predominant part of thorium present in solution as humic complexes. In a pH range where no organic coating onto silica occurs, there is a competitive reaction between Th(IV) sorption onto the silica surface and onto HA reactive functional groups. In this case, Schubert´s method is applied to obtain a global interaction constant for the Th(IV)-HA system. The large interaction constant values indicate a strong affinity of HA for Th(IV).

Abstract
This paper illustrates the coupling of Neutron Activation Analysis (NAA), Proton Induced X-ray Emission (PIXE) and X-ray Photoelectron Spectroscopy (XPS) to quantify iodine contents in natural humic substances from different geochemical origins and to determine its chemical environment. Non negligible contents of iodine from some hundreds of μg/g to more than one weight per cent have been quantified in the humic substances, and iodine seems to be attached to the organic matter by covalent bonds.
