Abstract
BACKGROUND Intimate partner violence (IPV) targeting women is probably underestimated during a woman's lifetime. Venous thromboembolism (VTE) is a multifactorial disease associated with haemostasis-activating conditions. Minor injuries can trigger VTE. OBJECTIVES We aimed to look for an association between VTE and IPV in women taking combined oral contraceptives (COCs) METHODS: We performed a multicentric, international, matched case-control study. Patients were women with a first VTE associated with COC intake. Controls were women taking COCs undergoing regular gynaecological check-ups. Patients and Controls were matched for country, age, length of COC intake and type (997 pairs). IPV was evaluated using the WAST self-administrated questionnaire. RESULTS IPV, defined as a WAST score value at least 5, was diagnosed in 33 Controls (3.3 %) and 109 patients (10.9 %), conditional odds ratio (OR): 3.586, 95 % confidence interval (2.404-5.549), p < 0.0001. After multivariate analysis, the adjusted OR was 3.720 (2.438-5.677), p < 0.0001. Sensitivity analysis using increasing WAST score thresholds confirmed the association. CONCLUSIONS A first VTE in women taking COCs is associated with IPV. This association can have strong human consequences but also raises significant medical issues, for instance on the haemorrhagic risk of anticoagulant treatments in abused women. Pathophysiological studies are warranted.

Abstract
Over the last decade, the concept of Clonal haematopoiesis of undetermined potential (CHIP) has emerged. Low frequency somatic mutations in hematopoietic cells can occur with age and might allow formation of clones in individuals with no characterized haematological pathology. These CHIP mutations are associated with an increased risk of cancer or atherothrombosis, and their prevalence are more and more studied in pathologies with an inflammatory component. In our study, we analysed, by next generation sequencing, the prevalence of CHIP mutation in 94 patients with deep venous thrombosis (DVT), distinguishing two clinical phenotypes: provoked distal and non-provoked proximal DVTs. We show that there is no difference in CHIP prevalence between these two groups, nor with a matched-aged control group. The number of mutation per patients and the affected genes remain also the same between the three groups. Consequently and despite the relative small number of patients in each cohort, it seems that CHIP is not a strong concern in venous thromboembolism.

Abstract
Background: NETosis occurs in the context of infection or inflammation and results in the expulsion of decondensed DNA filaments called NETs (Neutrophil Extracellular Traps) into the extracellular environment. NETosis activates coagulation and contributes to the thrombotic risk of inflammatory diseases. To date, two mechanisms of NETosis have been identified: suicidal NETosis, in which neutrophils die after expelling the filaments; and vital NETosis, in which expulsion appears without altering the membrane. Human pregnancy is associated with a mild pro-inflammatory state, which is increased in the event of complications such as preeclampsia (PE). NETosis has been observed in these situations, but the mechanism of its production has not yet been studied. The aim of our study was to evaluate the balance of vital vs. suicidal NETosis in normal pregnancy and in PE. Patients/Methods: Neutrophils from healthy volunteers were stimulated with plasma from normal pregnancies (n = 13) and from women developing preeclampsia (n = 13). Immunofluorescent labelling was performed to determine the percentages and origin of NETs in both groups. Inhibition with suicidal or vital NETosis inhibitors was also performed to validate our results. Results: We found a significant increase in NETs in women with PE compared to women with normal pregnancies. We showed that vital and non-vital NETosis are present in normal and preeclamptic pregnancies. We demonstrated that the higher proportion of NETs observed in PE was due to non-vital NETosis whose main component is represented by suicidal NETosis. Discussion: These results suggest the important part of non-vital NETosis in the pathophysiology of PE.

Abstract
Introduction Coronavirus disease 2019 (COVID-19) is a respiratory disease triggered by immunopathological mechanisms that cause excessive inflammation and leukocyte dysfunction. Neutrophils play a critical role in the innate immunity and are able to produce neutrophil extracellular traps (NETs: NETosis process) to combat infections. Some NETs markers are increased in patients who died from COVID-19. Recently, the neutrophil fluorescence variable (NEU-SFL), available on certain automated complete blood count (CBC) analyzers, has been correlated with NET formation and may reflect NETosis in patients. Here we evaluate whether NEU-SFL measured after admission of COVID-19 patients is associated with in-hospital survival or death. Patients and methods 1,852 patients admitted for severe COVID-19 at Nîmes University Hospital in 2021 were retrospectively included in the study: 1,564 who survived the hospital stay and 288 who did not. The NEU-SFL was obtained on the Sysmex™ XN-10® analyzer and values for survivors and non-survivors were compared. The intra-patient NEU-SFL variations between the hospital entry and the last day of hospitalization were also analyzed (IRB 22.06.01, NCT05413824). Results Non-survivors presented higher NEU-SFL values. NEU-SFL values above the 4th quartile were independently associated with a 2.88-fold risk of death. Furthermore, the difference of NEU-SFL values between the first and the last available data during hospitalization revealed that a decrease in NEU-SFL was associated to survivors and vice versa. Conclusion Our study reinforces the role of neutrophils and NETosis in the pathophysiology and prognosis of COVID-19. Further studies combining NEU-SFL with other NETosis markers could improve the management of COVID-19 patients.

Abstract
INTRODUCTION Limitations in the data used to define thromboprophylaxis for patients with antiphospholipid antibodies (aPLAbs) and thrombosis include uncertainties after an initial provoked venous thromboembolic event (VTE). We aimed to study such cases associated with combined oral contraceptive (COC) intake. METHODS We retrospectively analysed thrombotic outcomes after a first COC-associated VTE and positive aPLAbs, with a low risk HERDOO2 score, on low-dose aspirin (LDA) secondary thromboprophylaxis, seen from 2010 to 2021 in 3 tertiary referral centres, one in France and 2 in Russia. Data from 264 patients (distal deep vein thrombosis DVT: 62.9 %), cumulating in 1327.7 patient-years of observation, were collected. RESULTS There were 22 cases of thrombosis: 16 distal DVTs, 3 proximal, 1 pulmonary embolism (PE) and 2 transient ischemic attacks. Recurrence rate was 1.66 per 100 patient-years (p-y; 95 % CI: 0.96-2.33). No major bleeding occurred. Risk factors affecting recurrence-free survival were the time between first COC intake and VTE (p < 0.0001; the shortest, the lower), proximal DVT (p = 0.021), active smoking (p = 0.039), an associated systemic disease (p = 0.043) and circulating monocyte counts (p = 0.001). CONCLUSIONS We observed a low risk of recurrence which was modulated by classical risk factors for VTE. These observational data may provide clues for future randomized controlled trials.

Abstract
AbstractAntiphospholipid antibodies (aPL Abs) have long been associated with the occurrence of certain specific pregnancy morbidities, affecting both mother and fetus. Antithrombotic-based prophylactic regimens are the standard of care. Their intensity is modulated by the thrombotic history and has greatly improved the prognosis related to spontaneous morbidity. Observational studies show that this treatment is still associated with the persistence of excess of late-pregnancy placental diseases, calling for new or complementary developments, yet to be validated. Rigorous prospective multicentric validation of clinical and laboratory parameters capable of identifying those women and fetuses at a risk of pejorative evolution, thus early prognosis, is a priority issue. These will make it possible to develop customized treatments and test them. Furthermore, there are still concerns, particularly neurodevelopmental ones, about children born to aPL Ab-positive mothers, and clarification based on regular, more systematic evaluations is required. Even after pregnancy, women with a pure obstetrical antiphospholipid syndrome are at a greater risk of venous and arterial thrombosis over time, and prevention needs to be improved. These women also appear to develop more psychiatric and mood disorders. Central nervous system imaging using high-resolution techniques has shown subtle impairments in the white matter, associated with the most pathogenic aPL Abs and the clinical significance of this is under investigation. These mothers also seem to develop an excess of cancers. The systemic impact of aPL Abs is gradually being suspected, although this requires further evidence, and prevention should be envisaged.

Abstract
Pregnancy and puerperium increase the relative risk of venous thromboembolism (VTE) and the absolute risk remains low, around 1 per 1,000, with induced mortality of around 1 per 100,000. Analysis of large databases has helped specify the modes of presentation and risk factors (RF) whose impact is greater after than before childbirth, since VTE during pregnancy and post-partum obey different RFs. The evolution of the population concerned (mostly women over 35, obese, of multi-ethnicity undergoing medically assisted reproduction) affects the frequency of these RFs. Pulmonary embolism (PE) is over-represented after childbirth, but 30% of PE in pregnancy occurs without any RFs. Recommendations for prevention, mainly from expert groups, are heterogeneous and often discordant. Low molecular weight heparins (LMWH) are the mainstay of pharmacological thromboprophylaxis, in a field where randomized controlled studies are definitely lacking. VTE risk assessment in pregnancy must be systematic and repetitive. Risk assessment methods and scores are beginning to emerge to guide thromboprophylaxis and should be used more systematically. In the future, analyzing observational data from huge, nationwide registries and prospective cluster clinical trials may bring to light clinically relevant outcomes likely to feed comprehensive guidelines.

Abstract
BACKGROUND Few data are available on thrombotic outcomes during pregnancy and puerperium occurring after an initial provoked venous thromboembolic event (VTE). OBJECTIVES To describe thrombotic outcomes during pregnancy after a first combined oral contraceptive (COC)-associated VTE and the factors associated with recurrence Methods. This was an international multicentric retrospective study on patients referred for thrombophilia screening from January 1st 2010 to January 1st 2021 following a first COC-associated VTE, including women with neither inherited thrombophilia nor antiphospholipid antibodies and focusing on those who had a subsequent pregnancy under the same thromboprophylaxis treatment. Thrombotic recurrences during pregnancy and puerperium as well as risk factors for recurrence were analysed. RESULTS We included 2,145 pregnant women. A total of 88 thrombotic events, 58 antenatal and 29 postnatal, occurred, mostly during the first trimester of pregnancy and the first two weeks of puerperium. Incidence rates were 49.6 (37-62) per 1,000 patient-years during pregnancy and 118.7 (78-159) per 1,000 patient-years during puerperium. Focusing on pulmonary embolism, incidence rates were 1.68 (1-4) per 1,000 patient-years during pregnancy and 65.5 (35-97) per 1,000 patient-years during puerperium. Risk factors for antenatal recurrences were maternal hypercholestorolaemia and birth of a very small-for-gestational-age neonate. A risk factor for postnatal recurrence was the incidence of preeclampsia. Conclusions Our multicentric retrospective data show significant rates of VTE recurrence during pregnancy and puerperium in women with a previous VTE event associated with COC, despite a unique LMWH-based thromboprophylaxis. These results may provide benchmarks and valuable information for designing future randomized controlled trials.

Abstract
OBJECTIVE To explore the regulatory role of soluble CD146 (sCD146) and its interaction with galectin-1 (Gal1) in placenta-mediated complications of pregnancy. DESIGN Prospective pilot and experimental studies. SETTING University-affiliated hospital and academic research laboratory. PATIENT(S) One hundred fifteen women divided into three groups: 30 healthy, nonpregnant women, 50 women with normal pregnancies, and 35 with placenta-mediated pregnancy complications. INTERVENTION(S) Wound-healing experiments were conducted to study trophoblast migration. MAIN OUTCOME MEASURE(S) Quantification of sCD146 and Gal1 by enzyme-linked immunosorbent assay. Analysis of trophoblast migration by wound closure. RESULT(S) Concomitant detection of sCD146 and Gal1 showed lower sCD146 and higher Gal1 concentrations in women with normal pregnancies compared with nonpregnant women. In addition, follow-up of these women revealed a decrease in sCD146 associated with an increase in Gal1 throughout pregnancy. In contrast, in women with preeclampsia, we found significantly higher sCD146 concentrations compared with women with normal pregnancies and no modification of Gal1. We emphasize the opposing effects of sCD146 and Gal, since, unlike Gal1, sCD146 inhibits trophoblast migration. Moreover, the migratory effect of Gal1 was abrogated with the use of an anti-CD146 blocking antibody or the use of small interfering RNA to silence VEGFR2 expression. This suggests that trophoblast migration is mediated though the interaction of Gal1 with CD146, further activating the VEGFR2 signaling pathway. Significantly, sCD146 blocked the migratory effects of Gal1 on trophoblasts and inhibited its secretion, suggesting that sCD146 acts as a ligand trap. CONCLUSION(S) Soluble CD146 could be proposed as a biomarker in preeclampsia and a potential therapeutic target. CLINICAL TRIAL REGISTRATION NUMBER NCT 01736826.

Abstract
INTRODUCTION No reference values are currently available for coagulation assays performed for thrombophilia screening prescribed according to guidelines, after a first venous thromboembolic (VTE) event, and we have no idea of the intra-patient associations between results. METHODS We performed a retrospective study of consecutive prescriptions fulfilling guidelines in a French university hospital from 2010 to 2019 (n = 3842) from the Glims® laboratory information system. We collected results of 12 parameters: aPTT, PT, fibrinogen (Fg), one-stage clotting methods for factors VIII, IX, XI and II (FVIII, FIX, FXI, FII), antithrombin (using an amidolytic assay: AT), protein C and S (using clotting assays: PC and PS) and mixing tests of a lupus-anticoagulant sensitive aPTT and of DRVVT. RESULTS We show the results of the 12 parameters from 3603 individual files with less than 6 missing values, then describe these distributions and correlations between results from 2930 files with no missing value. We give the frequency of results described as indicating a risk of first VTE or of VTE recurrence. We propose 2 quantitative scores linking the 12 parameters at the individual level and reflecting their degree of dispersion with respect to their mean, describe the values of these scores and their associations with thrombophilic results. CONCLUSIONS These normal values should help laboratory workers to validate process results and to assess their degree of originality. Our 2 scores should help to determine the intra-patient plausibility of associations of results. The usefulness of these laboratory scores for predicting clinically-relevant outcomes deserves to be investigated.

Abstract
CD146 is an adhesion molecule essentially located in the vascular system, which has been described to play an important role in angiogenesis. A soluble form of CD146, called sCD146, is detected in the bloodstream and is known as an angiogenic factor. During placental development, CD146 is selectively expressed in extravillous trophoblasts. A growing body of evidence shows that CD146 and, in particular, sCD146, regulate extravillous trophoblasts migration and invasion both in vitro and in vivo. Hereby, we review expression and functions of CD146/sCD146 in the obstetrical field, mainly in pregnancy and in embryo implantation. We emphasized the relevance of quantifying sCD146 in the plasma of pregnant women or in embryo supernatant in the case of in vitro fertilization (IVF) to predict pathological pregnancy such as preeclampsia or implantation defect. This review will also shed light on some major results that led us to define CD146/sCD146 as a biomarker of placental development and paves the way toward identification of new therapeutic targets during implantation and pregnancy.

Abstract
INTRODUCTION Women with obstetric antiphospholipid syndrome (oAPS) still develop placental diseases, mainly pre-eclampsia (PEcl), which diagnosis is associated with reduced ADAMTS13 levels. Testing ADAMTS13 in newly pregnant oAPS may provide evidence for risk stratification. MATERIALS AND METHODS We retrospectively investigated the prognostic value of ADAMTS13 activity, antigen and antibodies on stored plasma samples obtained prior to beginning low-molecular weight heparin-low dose aspirin treatment in 513 oAPS women. RESULTS Some women had evidences of early positive ADAMTS13 antibodies and low ADAMTS13 activity:antigen ratio, suggestive of ADAMTS13 dysfunction. Women with a subsequent PEcl had higher ADAMTS13 antibodies (p < 0.0001), and lower ADAMTS13 activity and activity:antigen ratios (p < 0.0001). In multivariate analysis, these markers were significant risk factors for PEcl and for the most devastating PEcl subgroups (early-onset PEcl, severe PEcl, PEcl with no living child after 28 days). ADAMTS13-related markers showed acceptable discrimination power to predict clinical events, particularly for ADAMTS13 activity:antigen ratio in predicting PEcl cases with no living child after 28 days (AUC: 0.844 (0.712-0.974), p < 0.0001), with excellent negative predictive value (0.990). CONCLUSIONS The characterization of ADAMTS13 in newly pregnant women with oAPS depicts the risk of PEcl occurrence. ADAMTS13 might help identify pregnant women with oAPS not requiring escalating treatment strategies to prevent PEcl.

Abstract
BACKGROUND Placenta-mediated pregnancy complications generate short- and long-term adverse medical outcomes for both the mother and the fetus. Nucleosomes and free DNA (fDNA) have been described in patients suffering from a wide range of inflammatory conditions. OBJECTIVE The objective of our study was to compare nucleosomes and fDNA circulating levels during pregnancy and particularly in women developing a placenta-mediated complication according to the subtype (preeclampsia or intrauterine growth restriction) (NCT01736826). PATIENTS/METHODS A total of 115 women were prospectively included in the study across three groups: 30 healthy non-pregnant women, 50 with normal pregnancy, and 35 with a complicated pregnancy. Blood samples were taken up to every 4 weeks for several women with normal pregnancy and nucleosomes and fDNA were quantified using enzyme-linked immunosorbent assay and quantitative polymerase chain reaction, respectively. RESULTS We show that nucleosomes and fDNA concentrations significantly increase during normal pregnancy, with concentrations at delivery differing between the two groups. Interestingly, we show that concentrations differ according to the type of placenta-mediated complications, with higher levels in preeclampsia compared to intrauterine growth restriction. CONCLUSIONS These data suggest that nucleosomes and fDNA may be additional actors participating in placenta-mediated pregnancy complications.

Abstract
Normal pregnancy is associated with an increasing state of activation of the haemostatic system. This activation state is excessive in women with placenta-mediated pregnancy complications (PMPCs), including preeclampsia (PE). Platelet activation plays a crucial pathophysiological role in PE. The very early activation of coagulation in the intervillous space is mandatory for placental growth and morphogenesis but its excesses and/or inadequate control may participate to the emergence of the trophoblastic phenotype of PE. Extracellular vesicles, of endothelial but also of trophoblastic origin, can favour key cellular reactions of preeclampsia, acting as proactive cofactors. The understanding of this intricate relationship between haemostasis activation and PMPCs may provide interesting keys for new pathophysiological therapeutic developments.

Abstract
Malignancies can be associated with positive antiphospholipid antibodies but the incidence of cancer among women with the purely obstetric form of antiphospholipid syndrome (APS) is currently unknown. Our aim was to investigate the comparative incidence of cancers in women with a history of obstetric APS within a referral university hospital-based cohort (NOH-APS cohort). We performed a 17-year observational study of 1,592 non-thrombotic women with three consecutive spontaneous abortions before the 10th week of gestation or one fetal death at or beyond the 10th week of gestation. We compared the incidence of cancer diagnosis during follow-up among the cohort of women positive for antiphospholipid antibodies (n=517), the cohort of women carrying the F5 rs6025 or F2 rs1799963 polymorphism (n=279) and a cohort of women with negative thrombophilia screening results (n=796). The annualized rate of cancer was 0.300% (0.20%-0.44%) for women with obstetric APS and their cancer risk was substantially higher than that of women with negative thrombophilia screening [adjusted hazard ratio (aHR) 2.483; 95% confidence interval (CI) 1.27-4.85]. The computed standardized incidence ratio for women with obstetric APS was 2.89; 95% CI: 1.89-4.23. Among antiphospholipid antibodies, lupus anticoagulant was associated with incident cancers (aHR 2.608; 95% CI: 1.091-6.236). Our cohort study shows that the risk of cancer is substantially higher in women with a history of obstetric APS than in the general population, and in women with a similar initial clinical history but negative for antiphospholipid antibodies.

Abstract
OBJECTIVES Case reports describe neuropsychiatric manifestations associated with antiphospholipid antibodies (aPlAbs). In patients sharing the same symptoms fulfilling the antiphospholipid syndrome (APS) clinical criteria, the prevalence of common mental disorders has, however, never been studied. METHODS We observed women with three consecutive abortions before the 10th week of gestation or one foetal loss at or beyond the 10th week. We compared the prevalence of common psychiatric disorders detected through screening using the Mini International Neuropsychiatric Interview, 10 years after inclusion, in women with APS (n = 506), women negative for aPlAbs but carrying the F5rs6025 or F2rs1799963 thrombogenic polymorphism (n = 269), and women with negative thrombophilia screening results as controls (n = 764). RESULTS Similar prevalence values were obtained for controls and women bearing one of the two thrombogenic polymorphisms. Women with APS more frequently had mood disorders (relative risk (RR) 1.57 (1.262-1.953), P = .0001) and anxiety (RR 1.645 (1.366-1.979), P < .0001). Within the APS group, lupus anticoagulant (LA) and anti-β2GP1 IgG, or triple positivity, were strong risk factors for mood disorders. CONCLUSIONS Women with obstetric APS have a higher risk of positive screening for common mental disorders than women without APS.

Abstract
Essentials Nucleosomes and free DNA are two newly described biomarkers in venous thromboembolism (VTE). Reliability of nucleosomes, plasma free DNA and conventional hemostasis markers were studied. Hemostasis biological parameters vary over a short time-frame in VTE patients. Hemostasis biological parameters also vary over a short time-frame in healthy controls. SUMMARY Background Previous studies have associated neutrophil-derived circulating nucleosomes and plasma free DNA with venous thromboembolism (VTE). However, there are few data concerning these two biomarkers and no studies have compared the reliability of nucleosomes and plasma free DNA against that of conventional hemostasis markers. Objectives We performed a 3-year prospective study of nucleosomes and plasma free DNA levels in comparison with conventional hemostatic biomarkers and blood cells. Patients/Methods Fifteen healthy controls and 22 randomly selected patients with a history of VTE were followed monthly for 6 months. The reliability of these markers was evaluated by the intraclass correlation coefficient (ICCs). Results and Conclusions In healthy controls and patients, we found a low reliability for nucleosomes and plasma free DNA, with ICCs at 0.538 (95% confidence interval [CI], 0.334-0.764) and 0.091 (95% CI, -0.026-0.328), respectively, in the healthy controls, and at 0.213 (95% CI, 0.042-0.463) and 0.161 (CI 95%, 0.008-0.398) in the patient group. For the conventional hemostasis biomarkers and for blood cells, reliability ranged from poor to good in the healthy volunteers and from poor to acceptable in the patient group. Our study shows for the first time that hemostasis biological parameters spontaneously vary over a short time-frame in VTE patients and, more surprisingly, in normal individuals. The clinical value of such intra-individual variations is currently unknown. This variability might mean reinterpreting diagnostic or prognostic models based on static evaluation of individuals. Studying the intrinsic value of individual patterns of markers' variability is warranted.

Abstract
Antiphospholipid antibodies (APLAbs) are generally considered as risk factors for foetal death, for premature birth ≤34weeks due to severe pre-eclampsia or severe placental insufficiency and for recurrent consecutive spontaneous abortions <10weeks. Among these three obstetrical morbidities, only the first one is however not regularly questioned. The coexistence of an inflammatory disease and/or of thrombotic manifestations increases the obstetrical risks. Among the three criteria APLAbs, i.e. lupus anticoagulant (LA), anticardiolipin (aCL) Abs, anti-β2 glycoprotein-I (aβ2GP1)Abs, LA seems the more widely associated to clinical risks, the clinical impact of aβ2GP1Abs is progressively defined and the pejorative impact of triple positivity is still discussed. High quality prospective multicentric epidemiological studies are still awaited. The identification of predictors of pregnancy outcome is necessary to streamline the design and use of new treatments acting on pathophysiological molecular targets.

Abstract
Although progress was made in in vitro fertilization (IVF) techniques, the majority of embryos transferred fail to implant. Morphology embryo scoring is the standard procedure for most of IVF centres for choosing the best embryo, but remains limited since even the embryos classified as "top quality" may not implant. As it has been shown that i) CD146 is involved in embryo implantation and ii) membrane form is shed to generate soluble CD146 (sCD146), we propose that sCD146 in embryo supernatants may constitute a new biomarker of embryo selection. Immunocytochemical staining showed expression of CD146 in early embryo stages and sCD146 was detected by ELISA and Western-blot in embryo supernatants from D2. We retrospectively studied 126 couples who underwent IVF attempt. The embryo culture medium from each transferred embryo (n = 222) was collected for measurement of sCD146 by ELISA. Significantly higher sCD146 concentrations were present in embryo supernatants that did not implant (n = 185) as compared to those that successfully implanted (n = 37) (1310 +/- 1152 pg.mL-1 vs. 845+/- 1173 pg.mL-1, p = 0.024). Sensitivity analysis performed on single embryo transfers (n = 71) confirmed this association (p = 0.0054). The computed ROC curve established that the optimal sCD146 concentration for embryo implantation is under 1164 pg.mL-1 (sensitivity: 76%, specificity: 48%, PPV: 25% and NPV: 92%). Over this sCD146 threshold, the implantation rate was significantly lower (9% with sCD146 levels >1164 pg.ml-1 vs. 22% with sCD146 levels ≤ 1164 pg.mL-1, p = 0.01). Among the embryos preselected by morphologic scoring, sCD146 determination could allow a better selection of the embryo(s), thus improving the success of elective single embryo transfer. This study establishes the proof of concept for the use of sCD146 as a biomarker for IVF by excluding the embryo with the highest sCD146 level. A multicentre prospective study will now be necessary to further establish its use in clinical practice.

Abstract
The prognostic value of angiogenic factors in newly pregnant women with obstetric antiphospholipid syndrome (oAPS) has not been documented. We observed 513 oAPS who experienced three consecutive spontaneous abortions before the 10th week of gestation or one fetal loss at or beyond the 10th week. We assessed the plasma concentrations of the proangiogenic factor placenta growth factor (PIGF) and of the antiangiogenic factor soluble fms-like tyrosine kinase-1 on the eve and on the 4th day of the low-molecular weight heparin-low-dose aspirin treatment. Placenta growth factor and fms-like tyrosine kinase-1 plasma concentrations showed marked increases. Treatment-associated variations of PIGF and of soluble fms-like tyrosine kinase-1 were antagonist risk factors for placenta-mediated complications (PMC) and for severe PMC, for fetal death, stillbirth and neonatal death. The ratio between PIGF increase and soluble fms-like tyrosine kinase-1 was a summary variable whose best cut-off values (1.944.10−2) had high negative predictive values for PMC (0.918) and may be used to help rule out the development of PMC in evolutive pregnancies after 19 completed weeks. The early variations of PIGF and soluble fms-like tyrosine kinase-1 concentrations in newly pregnant oAPS may help to detect patients at low risk of PMC. (clinicaltrials.gov identifier: 02855047)

Abstract
The goal of this paper is to study the main uses of the residual imprint of the indentation test. It also discusses the different technologies and methods employed in this context. The difficulties encountered when trying to exploit the full potentials of the imprint are thoroughly examined. A survey of the literature on the quantification of the pile-up clearly shows that there is a lack of consensus on the measurement of the residual imprint as well as on treatment methods. Therefore, in order to widen the application fields of the indentation residual imprint, relevant and standardized indicators should be established.

Abstract
Fertility is a quantitative, complex character governed by a considerable number of genes. Despite clinical and scientific advances, several cases of human infertility remain unexplained. In the present study, using a positional cloning approach in a mouse model of interspecific recombinant lines, a candidate gene, ALPP, encoding the placental alkaline phosphatase, was identified as being potentially involved in recurrent spontaneous abortion. We then analyzed patients for detecting putative associations between ALPP polymorphisms, in vitro fertilization failures, and miscarriages. ALPP was sequenced in 100 controls and 100 patients affected by recurrent spontaneous abortion, from the same ethnic background. The frequency of several alleles and allelic combinations were different between recurrent spontaneous abortion and control women. One polymorphism induced a coding substitution (Ile89Leu) that was associated with a decreased risk of abortion and in vitro fertilization failure. Thereafter, the population was increased by the analysis of 92 additional controls and 612 additional patients for the coding polymorphism Ile89Leu. We finally show, by functional analysis, that the 89Leu placental alkaline phosphatase has an enhanced alkaline phosphatase activity. This study suggests that ALPP genotyping could be a strong predictor of implantation success.

Abstract
We evaluated an automated method for measuring low-density lipoprotein cholesterol (LDL-cholesterol) with Integra 800 (Roche Diagnostics). This method uses detergents which show selectivity for the different lipoproteins. Our evaluation has shown a within run imprecision of 2% and a between-assay imprecision of 1.2%. This method was not perturbed by haemoglobin, bilirubin or lipids. However, the reagents remain expensive: we will use it when calculation or interpretation of lipid results are not possible.

Abstract
BACKGROUND The purpose of this study was to determine whether laparoscopy could improve our ability to diagnose and treat perforations of the small bowel. METHODS From 1985 to 2001, among 250 patients admitted for a blunt abdominal trauma, 195 surgical explorations were performed, comprising 42 laparoscopies. On admission, 108 patients underwent an abdominal ultrasonography (US) and 104 a computed tomography (CT). Thirty-nine patients had a blunt small bowel trauma (BSBT) that was explored and/or treated by laparoscopy (n = 15) or celiotomy (n = 24). We compared the patients who underwent emergency surgery (23) and those who were operated on after a mean delay of 51 h. RESULTS On admission, for detecting free intraperitoneal fluid with a BSBT, the sensitivity of CT was 93.3% and specificity was 13.6%. Regarding the 23 patients who underwent emergency surgery, 8/20 had positive US and 10/15 had positive CT, whereas the 15 celiotomies and 8 laparoscopies indicated BSBT. Regarding the 16 patients who underwent delayed surgery, 9 patients underwent a celiotomy and 7 a laparoscopy; all BSBTs were diagnosed. In searching for BSBT, the sensitivity and specificity of laparoscopy were both 100%, whereas the sensitivity of CT was 83.3% and specificity was 22.2%. Twenty of 23 patients undergoing emergency surgery had bowel suture repair compared to 3/16 after delayed surgery. In contrast, a resection was necessary in 10/12 patients treated after a delay compared to 2/17 operated in emergency. Five BSBTs were sutured by laparoscopy, whereas 10 required conversion. Laparoscopy avoided celiotomy in 15 cases. There were no deaths and no enterostomy. CONCLUSION In hemodynamically stable patients with blunt abdominal trauma, laparoscopy safely and effectively identifies small bowel injuries. Early recognition of these injuries and timely surgical treatment offer the best prognosis.

Abstract
For cancer gene therapy, a recombinant adenovirus serotype 5 named RPR/INGN201 has been constructed by susbtitution of the E1 region with human tumor suppressor gene p53. The protein components of RPR/INGN201 virions were separated by reversed-phase HPLC and were individually identified by electrospray time-of-flight mass spectrometry and N-terminal sequencing, both on intact proteins and on their proteolytic fragments after trypsin digestion. Twenty-five peptide components of the proteome (including fiber) with greater than 0.25-0.5% contribution to the protein content of the virus were identified and characterized. Fiber was confirmed to be partially glycosylated (both the non-glycosylated and the monoglycosylated states were identified), and two proteins were isolated and identified as phosphorylation derivatives, namely protein V (non-phosphorylated and monophosphorylated) and protein IIIa (mono- and diphosphorylated). This new analytical tool proved to be very useful not only for refining our current knowledge of the polypeptide repertoire of purified infectious virions but also for monitoring and very rapidly identifying structural modifications resulting from changes in the manufacturing process. It was also used successfully for the characterization of various adenoviral constructs.

Abstract
Elliptic flow from nuclear collisions is a hadronic observable sensitive to the early stages of system evolution. We report first results on elliptic flow of charged particles at midrapidity in Au+Au collisions at square root(S)NN = 130 GeV using the STAR Time Projection Chamber at the Relativistic Heavy Ion Collider. The elliptic flow signal, v2, averaged over transverse momentum, reaches values of about 6% for relatively peripheral collisions and decreases for the more central collisions. This can be interpreted as the observation of a higher degree of thermalization than at lower collision energies. Pseudorapidity and transverse momentum dependence of elliptic flow are also presented.

Abstract
AIM OF THE STUDY The aim of this prospective non-randomized study was to compare Stoppa's technique to laparoscopic approach in totally extraperitoneal repair of bilateral inguinal hernia. PATIENTS AND METHOD From December 1996 to December 1998, 117 consecutive patients with 234 hernias underwent either Stoppa's technique (74 patients) or a totally extraperitoneal laparoscopic approach (43 patients). Patients were randomized in two groups according to the surgeon to whom they were referred. All patients were reviewed in December 1999. RESULTS There was no mortality. Complications occurred in 3% of patients after Stoppa's technique (group S) and in 4% of patients in the laparoscopic group (group L). The conversion rate was 7% (3 cases). Postoperative analgesia use, hospital stay, and duration of disability were significantly shorter in group L, the cost was lower, but the operating time was significantly longer than in group S. Recurrence rates were similar in the two groups: 2% in group S, 1.1% in group L. CONCLUSION The laparoscopic approach appears to be preferable to Stoppa's technique in the treatment of bilateral inguinal hernia.

Abstract
Locoregional extensions are often observed in tumors of the duodenojejunal angle, either because of their anatomic situation or in cases diagnosed late. Endoscopic and radiographic explorations (basically abdominal CT scan) are indicated to search determine the degree of extensions to neighboring organs and vessels. Colic and mesocolic involvement are at the limit of preoperative explorations. Based on 4 observations of increasing complexity, we describe our operative strategy allowing tumor exeresis in a single block. Extension to the superior mesenteric artery is the main contraindication for exeresis.

Abstract
We reported a case of papillary and cystic tumor (Frantz's Tumor) associated with familial adenomatous polyposis in a young man, 29 years old. This case emphasized the interest of fine needle biopsy and the difficulties for determination of the final pathology. Close long term follow up is essential as local recurrencies and metastasis in the long term had been recorded, undergoing resection with curative intent. Papillary and cystic tumors should be resected.

Abstract
The authors report about two observations of cystic lymphangioma of the right colon. The patients complained of intermittent abdominal pain. Preoperative diagnosis is based on endoscopic findings (2 cases) and computed tomography films (1 case). A colonic carcinoma is associated in one case. Endoscopic polypectomy will be curative for pedunculated or small lymphangiomas. In other cases segmental resection seems to be the treatment of choice.

Abstract
An enquiry into sudden infant death syndrome (SIDS) in 1987 furnished us with detailed epidemiological data for 281 cases that underwent a thorough post-mortem examination. This analysis uses these data to evaluate the role the autopsy plays in explaining sudden death. The cases were classified into three diagnostic groups: explained causes of death (group 1), unexplained deaths with anomalies (group 2), and no anomaly (group 3). These 281 cases show the three essential features that characterize SIDS: over-representation of males, increased deaths during the second and third months of life, and increased deaths during winter. The autopsy examination revealed that many of these deaths had a medical explanation. Almost half were assigned to group 1. At the time of autopsy, no precise pathology could be diagnosed for 147 deaths; of these, 140 showed histological anomalies. There were only seven sudden deaths for which no abnormal sign was evident at the autopsy. These results are compared with those of similar studies and discussed in connection with three factors: the initial selection of cases, the nature and degree of the investigations, and the possible interpretations of the symptoms uncovered.

Abstract
The authors present a new case of a well-differentiated papillary mesothelioma of the peritoneum. This is an uncommon tumor which have a slow evolution like a low malignant potential tumor. But, because of its tendency to recurrence, the designation of Well-Differentiated Tumor is better. The diagnosis with others peritoneal tumors is sometimes difficult, especially with the Peritoneal Serous Tumors. Tumor recurrence must be treated by curative surgery. Adjuvant therapy is discussed for the diffuse form.
