Introduction: Lymphoma incidence continues to rise in France since early 80', although differently among subtypes. Recent improvements in patient survival in major lymphoma subtypes at populational level raise new questions about patient outcome (in specific subgroups) and survivorship (i.e. quality of life, long term sequelae). Numerous epidemiological studies have investigated factors related to lymphoma risk, but far fewer have addressed the extent to which socioeconomic status, social institutional context (i.e. healthcare system), social relationships, environmental context (exposures), individual behaviours (lifestyle) or genetic determinants influence lymphoma outcomes, especially in the general population. Moreover, the knowledge of the disease behaviour achieved from clinical trials data is partly biased because of patient selection. Study Design and Methods: The REALYSA ("REal world dAta in LYmphoma and Survival in Adults") study is a real-life multicentric cohort set in France areas mostly covered by population-based cancer registries to study the prognostic value of epidemiological, clinical and biological factors with a prospective 9-year follow up. ClinicalTrials.gov identifier is NCT03869619. We aim to include 6000 patients over 4 years. Adult patients without lymphoma history and newly diagnosed of one of the following 7 lymphoma subtypes (diffuse large B cell (DLBCL), follicular (FL), marginal zone (MZL), mantle cell (MCL), Burkitt, Hodgkin (HL), T-cell (T-NHL)) are offered to participate during a medical consultation with their hematologist. Exclusion criteria are: having already received anti-lymphoma treatment (except pre-phase) and having a documented HIV infection. After having given signed informed consent, participants fill in three auto-questionnaires regarding lifelong history of residences and occupations, quality of life (QoL / QLQ-C30 questionnaire) and social support (SS / SSQ6 questionnaire). Patients are then interviewed to collect their sociodemographic characteristics, medical and familial history, professional and domestic exposures to major chemicals and pesticides, lifestyle and women health. Clinical data are obtained using patients medical records, including care pathway, medical history, concomitant treatments, initial diagnosis characteristics, nodal/extra-nodal involvement, exams performed, staging, laboratory data, serologic tests, geriatric screening (G8 questionnaire), treatments received (including pre-phase, detailed treatment phases and molecules, reasons for treatment discontinuation), progressions, and treatment response evaluation. Biological samples at baseline and during treatment are collected including plasma and peripheral mononuclear cells. Additionally, a virtual tumor biobank is constituted for baseline tumor samples. The diagnosis will be ensured thanks to the review of French Lymphopath network. Follow-up, including clinical outcomes, new morbidities, lifestyle, professional situation, QoL, SS, fertility, health behavior, are collected every 6 months in the first 3 years and every year thereafter. Results: A pilot phase was implemented between November 2018 and June 2019 in 7 French hospitals/clinics. By June 30, 328 patients were recruited. Biological samples at baseline were obtained for 81% of included patients (n=265). 52% were male and 48% were female. The median age was 62 years (range: 18-95). The histological subtypes were the following (n=308 patients with complete data): 132 DLBCL (42.8%); 59 FL (19.5%); 52 HL (16.9%); 29 MCL (9.4%); 22 MZL (7.1%); 13 T-NHL (4.2%); 1 other (0.3%). We observed a good adherence to clinical research process despite the complexity of data collection. An extension phase with 10 additional centres will be launched during the last 2019 trimester. Discussion: The pilot phase of REALYSA study showed a good compliance to study guidelines and a good quality of data collected at baseline. Consequently, the study design is prospectively feasible in real-life setting. This cohort will constitute an innovative platform for clinical, biological, epidemiological and socio-economical research projects.

Maternal hypercoagulability is a possible cause of miscarriage during the eighth and ninth weeks of pregnancy, when the placenta replaces the yolk sac. We thus examined associations between putative markers of an acquired hypercoagulable state and the risk of first miscarriage. We conducted a case-control study comparing 743 women who miscarried in weeks 8 and 9 with 743 women who underwent a first provoked abortion, matched for age, number of pregnancies, and time elapsed since abortion. Levels of plasma homocysteine and of various antiphospholipid/antiprotein and hemostasis-related autoantibodies were categorized in 4 strata (percentiles 1-80, 81-95, 96-99, 100 among control patients) and analyzed in conditional logistic regression models. Pregnancy loss was independently associated with positive lupus anticoagulant (matched odds ratio [OR], 2.6; 95% confidence interval [CI], 1.1-6.0), high levels of immunoglobulin M (IgM) antibodies against cardiolipin (OR for percentile 100 versus 0-80, 3.5; CI, 1.2-10.1) and against phosphatidylethanolamine (OR, 4.7; CI, 1.9-12.1), high levels of IgG antibodies against annexin V (OR, 3.2; CI, 1.1-9.1) and against tissue-type plasminogen activator (OR, 19.5; CI, 7.9-48.0), and high homocystinemia (OR, 4.1; CI, 1.3-12.5). A first early pregnancy loss is associated with increased levels of several autoantibodies and of homocysteine. (Blood. 2003;102:3504-3513)

Gris, Jean-Christophe Bouvier, Sylvie Molinari, Nicolas Galanaud, Jean-Philippe Cochery-Nouvellon, Eva Mercier, Erik Fabbro-Peray, Pascale Balducchi, Jean-Pierre Mares, Pierre Quere, Isabelle Dauzat, Michel; The incidence of thrombosis in the purely obstetric form of antiphospholipid syndrome is uncertain. We performed a 10-year observational study of 1592 nonthrombotic women who had experienced 3 consecutive spontaneous abortions before the 10th week of gestation or 1 fetal death at or beyond the 10th week of gestation. We compared the frequencies of thrombotic events among women positive for antiphospholipid Abs (n = 517), women carrying the F5 6025 or F2 rs1799963 polymorphism (n = 279), and women with negative thrombophilia screening results (n = 796). The annual rates of deep vein thrombosis (1.46%; range, 1.15%-1.82%), pulmonary embolism (0.43%; range, 0.26%-0.66%), superficial vein thrombosis (0.44%; range, 0.28%0.68%), and cerebrovascular events (0.32%; range, 0.18%-0.53%) were significantly higher in aPLAbs women than in the other groups despite low-dose aspirin primary prophylaxis. Women carrying 1 of the 2 polymorphisms did not experience more thrombotic events than women who screened negative for thrombophilia. Lupus anticoagulant was a risk factor for unprovoked proximal and distal deep and superficial vein thrombosis and women in the upper quartile of lupus anticoagulant activity had the highest risk. Despite data suggesting that aPLAbs may induce pregnancy loss through nonthrombotic mechanisms, women with purely obstetric antiphospholipid syndrome are at risk for thrombotic complications
