Abstract
OBJECTIVE Although the risk for thrombosis is well documented for inflammatory bowel disease (IBD) patients, the underlying pathological mechanism seems to be different from other thrombotic conditions. Deciphering the actors responsible for the increased risk of thrombosis in IBD would help to improve management of this frequent complication. DESIGN We studied the interplay between platelets, coagulation, and von Willebrand factor (VWF) in 193 IBD patients and in experimental models (acute and chronic) of colitis in wild-type and VWF-deficient mice. RESULTS We found a platelet-dependent increase in thrombin generation in IBD patients and in our mouse model of colitis. Agglutinated platelets were present in the blood of patients and mice. Interestingly, we observed not only a significant increase in total VWF antigen, but we were able to detect the presence of active VWF (VWF in its platelet-binding conformation; 3.2±2.7µg/ml) in the plasma of 30% of all IBD patients. In healthy controls, active VWF levels were below 0.3µg/ml. This led us to further explore experimental colitis in VWF-deficient mice and we observed that these mice were protected against the procoagulant state triggered by the colitis. Unexpectedly, these mice also manifested a significant worsening of colitis severity both in acute and chronic models. CONCLUSION Platelets and VWF (including its active form) appear to be central players in the procoagulant phenotype in IBD. We observed that the role of VWF in hemostasis differs from its role in colic tissue healing, potentially opening new therapeutic avenues for a life-threatening complication in IBD patients.

Abstract
BACKGROUND Since the 1970s, there has been a quantitative and qualitative decline in sperm parameters. The main hypothesis to explain such a rapid evolution is the involvement of environmental and behavioral phenomena. METHODS A bibliographic search limited to English and French literature in men published before 7/2023 was carried out on the links between fertility and pollution, xenobiotics, tobacco, narcotics, cannabis, alcohol, weight, sport, sedentary lifestyle, sleep and anabolics. RESULTS Profound changes in lifestyle have occurred over the past 50 years: reduced sleep time, sedentary lifestyle, dietary changes, tobacco consumption, use of narcotics and anabolics. These changes have a proven impact on spermogram parameters, and should be corrected in an effort to optimize reproductive health. Other environmental parameters: pollution, exposure to heavy metals, exposure to xenobiotics, phthalates and pesticides… will be more difficult to exclude from patients' daily lives, but deserve to be taken more into account. CONCLUSION This review should help the urologist to assess and counsel patients in order to improve their reproductive health. These factors should be routinely investigated in infertile men.

Abstract
Triose phosphate isomerase (TPI) is a crucial enzyme for glycolysis. TPI deficiency is an autosomal recessive metabolic disease described in 1965, which remains exceptional by its rarity (less than 100 cases described worldwide), but by its extreme severity. Indeed, it is characterized by a chronic hemolytic anemia, an increased susceptibility to infections and especially, a progressive neurological degeneration which leads to death in early childhood for the majority of cases. We report in our observation the history of diagnosis and clinical course of monozygotic twins born at 32 WA with triose phosphate isomerase deficiency.

Abstract
INTRODUCTION Interferences on red blood cells (RBCs) measurement and the associated parameters in haematology analyzers are very common. Many sources of interferences are described but their management remains uncertain depending on the measurement system; we aimed at developing an optimized scheme allowing the accurate management of most interferences affecting RBCs, based on the alternative "optical" parameters from SYSMEX XN-10. METHODS Samples from 12 groups of relevant interferences were analysed and compared with a control group allowing (1) the determination of deviation thresholds beyond which an interference is likely, and (2) the development of two flowcharts for their subsequent management. These flowcharts were then evaluated among a bank of retrospective typical cases of interferences and in the routine flow of the laboratory. RESULTS After verifying the excellent agreement between standard and alternative parameters, the comparative study between analytical channels allowed to determine an acceptable deviation and then discriminate technical concerns caused by cold agglutinins, leukocytosis and plasma-related interferences. This led to the development of flowcharts ensuring the accurate management of these interferences, whether MCHC is <320 or >365 g/L. These proposed flowcharts allowed the correction of 63/65 historical confirmed interferences cases (97%). Furthermore, they corrected 18 results among 901 unselected prospective samples. CONCLUSION The resulting flowcharts allow a relevant correction for most common interferences affecting RBCs and are now definitively included in the routine analytical management and will be directly incorporated in the middleware of the laboratory.

Abstract
Study question
What are the motivations, experience, and acceptability of thermal male contraception (TMC) in men using TMC as the only couple contraceptive ?
Summary answer
Men wished to share the role of providing contraception in a couple and to avoid the use of hormones. Sexual satisfaction was significantly improved.
What is known already
Two male contraceptive methods inducing spermatogenesis suppression have achieved contraceptive efficacy, on a large population for hormonal contraception and a smaller one for thermal contraception (TC). The suppression of sperm counts to below 1 million/mL results in fertility rates commensurate with female pills. TC is obtained by wearing 15 hours/day a contraceptive underwear (CU) inducing a 2°C increase in testicular temperature (Mieusset & Bujan 1994). As no commercially available male thermal contraceptive exists, little information regarding the acceptability of this approach to men has been reported and only one publication analysed the hypothetical acceptability of TMC (Amouroux et al. 2018).
Study design, size, duration
We contacted 72 men who had started the CU testing phase between June 2011 and September 2019. The participants completed an anonymous online survey of 93 questions exploring population characteristics, contraceptive histories, motivations for choosing TC, patient experience at the successive phases of use, relations with partner and environment, and satisfaction with TC. Sexual life was evaluated by rating (1 to 4): frequency and pleasure of sexual intercourse, sexual desire, morning and intercourse erections.
Participants/materials, setting, methods
Among men who had reached the contraception use phase, the quality ratings of sexual life were compared over time, from the contraceptive method used before TC (“N-1” method) to the 2 previous methods (“N-2” and “N-3”)): “N-3” versus “contraception use phase”, “N-3” versus “CU testing phase,” and “CU testing phase” versus “contraception use phase.” These comparisons were made for all 5 sexual life parameters by a paired samples Wilcoxon signed rank test.
Main results and the role of chance
Sixty-seven men responded (93% response rate);63 participated in the survey (94% participation rate). The median age was 31 [21-52], 30 men (48%) had a Master’s degree or more, 49 (78%) had no child and 24 (38%) no parental project. Among the men whose couple's contraception method immediately before TC (N-1) was a female method (n = 36/63, 57%), the 2 main reasons for switching to a male method were the wish to share the role of providing contraception in a couple (n = 31/36, 86%) and the willingness to take responsibility for contraception (n = 21/36, 58%). The main motivations for choosing TC were “not using hormones” (n = 59/63, 94%) and using a method regarded as “natural” (n = 49/63, 78%). Most of men (68%) adopted the method in less than 2 weeks. During the contraception use phase (n = 59 men), they described: i) significantly improved sexual satisfaction (3,49±0,29/4) compared to that experienced with previous contraceptive methods (3,27±0,58/4;p<0,01); ii) high female partner confidence (100% rather/totally confident partner) and support (88% rather/totally supporting partner); iii) improved self-esteem (n = 35/59, 59%). The main negative point was discomfort, reported by 24% of the men.
The overall satisfaction score of using TC was 3.78±0.46/4, and 100% would recommend TC to other men.
Limitations, reasons for caution
The study population may seem small (63 men). However, it is not different from that of the previously pubished studies on men using hormonal contraception, which included 20, 38, 79 and 57 men, respectively. Our study also lacked a similar questionnaire for the female partners.
Wider implications of the findings
Men using TC successfully assumed the responsibility for and performed a daily task to provide couple contraception. This positive evaluation of TC together with its previously published contraceptive efficacy and reversibility on a small population, should encourage the development of this method.

Abstract
Abstract
Study question
What is the proportion of men treated for testicular cancer or lymphoma who banked sperm before gonadotoxic treatment in France?
Summary answer
In 2018, 41% of men with testicular cancer and 28% of men with lymphoma banked sperm before gonadotoxic treatment in France.
What is known already
Cancer treatments significantly improved survival rates in men. In Europe, the 5-year survival rate is above 90% for testicular cancer (TC) and Hodgkin lymphoma (HL), which, with Non Hodgkin Lymphoma (NHL), are the most frequent cancers in men of reproductive age. However, surgery, chemotherapy and/or radiotherapy may damage male fertility: between 15% and 30% of men remain permanently infertile after treatment. Since 2011, the French bioethics law recommends and guarantees free access to fertility preservation for all patients needing gonadotoxic treatments. Few international data are available about the rate of male cancer patients who receive sperm cryopreservation before cancer treatment.
Study design, size, duration
We analyzed the data of male cancer incidence in 2018 published by the French National Institute of Cancer (INCa), only available and latest French national data, estimated from cancer registers of selected metropolitan departments (Defossez et al. 2019). We organized a survey among the 27 metropolitan centers of the CECOS network (public centers for study and conservation of human eggs and sperm) to collect the annual number of sperm cryopreservations for TC, HL or NHL.
Participants/materials, setting, methods
We compared the number of 0-59 years-old men with TC, HL or NHL in metropolitan France (extracted from 2018 INCa data) and the number of sperm banking for TC, HL or NHL in metropolitan centers of the CECOS network.
Main results and the role of chance
INCa estimated that 38,048 new cancers were diagnosed in metropolitan France in 2018 in men aged 0-59 years. TC accounted for 2,630 new cases and lymphomas for 3,913 new cases (943 HL and 2,970 NHL).
Twenty-six out of 27 metropolitan CECOS centers answered the survey (96% participation rate): in 2018, 1,079 men banked sperm for TC, 375 for HL and 211 for NHL.
In 2018, the fertility preservation rate in metropolitan France was 41% for TC and 28% for lymphomas (51% for HL, and 15% for NHL). The results of our national study are in accordance with Uçar et al. 2020, a monocentric study on 110 TC patients showing a 43% fertility preservation rate, but differ from those of Abdel-Razek et al. 2020, a monocentric study on 59 NHL and 26 HL patients, showing respectively 32% and 14% fertility preservation rates.
A limit of our study is to be based on estimated cancer incidence from INCa reports without stratification on age and parenthood; sperm banking activity was measured in the CECOS network, which performs 90% of French male fertility preservation (French Biomedicine Agency 2018 data). This design may induce an underestimation of cancer incidence and of sperm banking activity.
Limitations, reasons for caution
Our study did not consider patients who were informed of fertility preservation but did not want to/could not bank ejaculated sperm (azoospermia, sperm collection failure, no-show). In CECOS network, the estimated rate of such patients is 10%.
French overseas regions were not studied (lack of INCa data).
Wider implications of the findings
Our results suggest that despite the recommendations and facilities offered by the French bioethics law, the male patients’ pathway for fertility preservation before cancer treatments could be improved. Further study should evaluate if this suboptimal rate of fertility preservation is homogeneous on French territory or related to postal code.

Abstract
Study question
Among health professionals involved in contraceptive prescribing, what are the knowledge, professional attitudes and training on male contraceptive methods?
Summary answer
The health professionals involved in prescribing contraception are not sufficiently trained in male contraception and almost all of them want more.
What is known already
The most recent large-scale studies show that 70% of couple contraception is provided by women and that the majority of men and women would be willing to adopt male contraception as couple contraception. The medicalization of contraception places the medical profession at the forefront of the acceptability of and information regarding a contraceptive method. However, only one study have evaluated health professionals’ knowledge of the various methods of male contraception (MC), including male hormonal contraception (MHC) and male thermal contraception (MTC).
Study design, size, duration
Between April 2020 and June 2020, we carried out a descriptive prospective multicentre study in a medical population of 2243 prescribers of couple contraception in France.
Participants/materials, setting, methods
The participants were obstetrician-gynaecologists, medical gynaecologists, general practitioners or midwives. They completed a three-part numerical questionnaire, including i) sociodemographic characteristics and personal experiences with contraception, ii) knowledge and professional attitudes about male contraception and iii) training on male contraception.
Main results and the role of chance
The overall participation rate was 19% (340/2243). Condoms and withdrawal were known by 98% and 89% of the population, respectively. Vasectomy was known by 75% of the population and significantly better known by obstetrician-gynaecologists than by medical gynaecologists and general practitioners (p = 0.026). Male hormonal contraception (MHC) and male thermal contraception (MTC) were known by 10% and 23% of the population, respectively, and were significantly better known by medical gynaecologists and general practitioners than by other specialties (p < 0.001). More than half (55%) of the population never or infrequently offered MC during a couple’s contraceptive request consultation. Female practitioners offered MC significantly more often than male practitioners (48% vs. 26%; p = 0.033). Only 14% of the population had ever participated in training on MC, 96% wished to be better trained on MC, and 86% expressed a willingness to participate in such a training.
Limitations, reasons for caution
The population was mainly representative of medical health practitioners of southeastern France. There was an over-representation of women in all medical specialties, except for midwives.
Wider implications of the findings: Our study shows that health professionals involved in contraception have limited knowledge about MC and are eager to have more information about it. To advance the acceptability and dissemination of such contraceptive methods, it seems imperative to provide health professionals with an adapted training program on male contraception.

Abstract
Study question
What are the risk factors for environmental reprotoxic exposure in infertile patients?
Summary answer
The most represented categories of reprotoxic risk factors (RRF) were dietary exposures (86% of patients), overweight (46%), psychoactive substances (38%) and male occupational exposures (63%).
What is known already
Numerous studies have reported the deleterious effects of environmental reprotoxic exposures on male or female fertility.
These studies most often focus on the impact of a limited number of reprotoxic risk factors (body mass index (BMI), dietary habits, tobacco or alcohol consumption) or a limited number of chemical or physical reprotoxic exposures: phthalates, occupational exposures, or pesticides.
Despite the call of several reproductive health professional societies and public health agencies for taking environmental health into account in women of childbearing age, this approach remains little realized in current practice.
Study design, size, duration
We conducted a prospective, monocentric study between June 2018 and February 2020 in women and men visiting the fertility unit of our University Hospital for assisted reproduction technique (ART) treatment.
Participants/materials, setting, methods
Patients completed a self-questionnaire to collect information about i) the various types of exposure to RRF, and ii) frequency and intensity of exposures (qualitative and semi-quantitative approach).
We performed a literature search in order to define the environmental factors and the exposure level thresholds associated with a “recognized” or “suspected” RRF and we analyzed their nature and number in patients.
Main results and the role of chance
During the inclusion period, we received 545 couples in consultation, and 405 were included in this study (810 patients/1090, participation rate: 74%). 65% of women and 68% of men self-reported at least one “recognized” RRF. In men, they were from exposure to solvents, heat, psychoactive substances and a BMI>25; in women, from exposure to poor indoor air quality, psychoactive substances and a BMI>25. A limited number of recognized risk factors were recorded in the majority of patients (one, two or three risk factors in 65% of patients).
Men were more often exposed than women to occupational risk factors (63% of men versus 28% of women) such as solvents and ambient heat, and women were more often exposed than men to poor indoor air quality and volatile organic compounds (49% of women versus 30% of men). We note that the majority of the risk factors for reprotoxic exposure found were modifiable, specifically dietary, occupational, overweight and psychoactive substance exposures.
Limitations, reasons for caution
One limitation is the collection of data via a self-administered questionnaire, which makes it possible to estimate the risk factors for reprotoxic exposure, but not to detect them in a measurable way, for example, through exposure biomarkers. In addition, no data is available about all RRF in the general population.
Wider implications of the findings: We suggest that if the individual screening of each infertile patient’s RRF was done before ART, most patients could act on a limited number of modifiable RRF, in the aim of increasing their chances of natural pregnancy and improving ART outcomes.

Abstract
BACKGROUND Diagnosis of heparin-induced thrombocytopenia (HIT) requires pretest probability assessment and dedicated laboratory assays. OBJECTIVE To develop a pretest score for HIT. DESIGN Observational; analysis of prospectively collected data of hospitalized patients suspected with HIT (ClinicalTrials.gov NCT00748839). SETTING Thirty-one tertiary hospitals in France, Switzerland, and Belgium. PATIENTS Patients tested for HIT antibodies (2280 evaluable), randomly allocated to derivation and validation cohorts. MEASUREMENTS Independent adjudicators diagnosed HIT based on the prospectively collected data and serotonin release assay results. RESULTS Heparin-induced thrombocytopenia was diagnosed in 234 (14.7%) and 99 (14.5%) patients in the two cohorts. Eight features were associated with HIT (in brackets, points assigned for score calculation of the score): unfractionated heparin (1); therapeutic-dose heparin (1); cardiopulmonary bypass (cardiac surgery) (2); major trauma (3); 5- to 21-day interval from anticoagulation initiation to suspicion of HIT (4); ≥40% decrease in platelet count over ≤6 days (3); thrombotic event, arterial (3) or venous (3). The C-statistic was 0.79 (95% CI, 0.76-0.82). In the validation cohort, the area under the receiver operating characteristic curve was 0.77 (95% CI, 0.74-0.80). Three groups of scores were defined; HIT prevalence reached almost 30% in the high-probability group. LIMITATION The performance of the score may depend on settings and practices. CONCLUSION The objective, easy-to-collect, clinical features of HIT we evidenced were incorporated into a pretest score, which may guide clinical decisions regarding diagnostic testing and anticoagulation.

Abstract
OBJECTIVES For 15 to 30% of infertile couples, no etiology can be found, leading to the diagnosis of "unexplained infertility". The aim of our study was to identify prognostic factors for live birth following in vitro fertilization (IVF) for these couples. METHODS A retrospective, monocentric study on a cohort of couples undergoing IVF for unexplained infertility with the woman aged≤40 years old. Primary analysis compared couples with a live birth following IVF versus childless couples following IVF. RESULTS Between January 2014 and December 2018, 104 couples were included, 196 transvaginal oocyte pickup were performed, followed by 234 embryo transfers (fresh or cryopreserved) which resulted in 43 deliveries. The cumulative live birth rate was 40.4% per couple. Before IVF attempts, no clinical or paraclinical prognostic factors between the two groups was observed. However, multivariate analysis showed several biological factors of good prognosis in course of treatment, such as a higher number of mature oocytes and better quality embryos in "live birth" group. CONCLUSIONS For a couple, the chances of having a child following IVF unexplained infertility are 40.4%. However, no clinical characteristic enabled us to identify favourable or unfavourable prognosis factors before starting ART. The prognostic factors identified during IVF cycle are interesting to advise or not to pursue IVF.

Abstract
The optimization of adoptive transfer approaches of anti-tumor T cells requires both the functional improvement of the injected T cells and the modulation of the tumor microenvironment, favoring the recruitment of these T cells and their activation. We have recently shown the therapeutic benefit of two approaches tested individually in a melanoma model wich were on one hand the adoptive transfer of specific T cells deficient for the expression of the inhibitory receptor PD-1, and on the other hand PD-L1 targeted alpha therapy (TAT). In this study, we sought to investigate the efficacy of these two therapies combined, compared to each monotherapy, in order to evaluate the synergy between these two approaches, in the same melanoma model. Here we used melanoma-specific T-cell clones, previously validated for the edition of PDCD1 gene and with previously demonstrated superior anti-tumor activity than their wild-type counterparts, after adoptive transfer in NSG mice engrafted with PD-L1 expressing human melanoma tumors. We also used a previously validated TAT approach, using a 213Bi-anti-human-PD-L1 mAb, alone or in combination with adoptive cell transfer, in the same mouse model. We confirmed previous results obtained with each monotherapy and documented the safety and the superior ability of a combination between the adoptive transfer of PD-1 deficient T cells and TAT targeting PD-L1 to control the growth of melanoma tumors in NSG mice. This study provides the first proof-of-concept of the efficacy of a combination therapy using TAT, adoptive cell transfer and genomic editing of IC-coding genes.

Abstract
INTRODUCTION ST Genesia is a new automated system enabling quantitative standardized evaluation of thrombin generation (TG), for example, in patients receiving anti-Xa direct inhibitors (xabans). Data on its analytical performances are scarce. METHODS Over an 18-month period, repeatability, reproducibility, and accuracy were assessed using STG-ThromboScreen (without or with thrombomodulin) or STG-DrugScreen reagents (corresponding to intermediate/high tissue-factor concentration, respectively), and controls. Furthermore, reproducibility was assessed using commercialized lyophilized and frozen normal pooled plasmas. Rivaroxaban and apixaban impacts on TG parameters were assessed using spiking experiments. Finally, a comparison with the Calibrated Automated Thrombogram method (CAT) (PPP reagent) was performed using plasma from healthy volunteers enrolled in the DRIVING-studyNCT01627665) before and after rivaroxaban intake. RESULTS For all dedicated quality control (QC) levels, inter-series coefficients of variations (CV) were <7% for temporal TG parameters, peak height (PH), and endogenous thrombin potential (ETP), whether results were normalized with a dedicated reference plasma STG-RefPlasma or not. Noteworthy, STG-RefPlasma used for normalization displayed substantially high PH and ETP. Mean biases between the observed and manufacturer's assigned QC values were mostly <7%. Both rivaroxaban/apixaban plasma concentrations were significantly associated with TG parameters. Finally, Bland-Altman plots showed a good agreement between ST Genesia-STG-ThromboScreen and CAT method within the explored range of values, although biases could be observed (PH: 16.4 ± 13.2%, ETP: 17.8 ± 11.9%). CONCLUSION ST Genesia® enables the reliable measurement of TG parameters in both in vitro and ex vivo xaban plasma samples using either STG-ThromboScreen or STG-DrugScreen according to xaban concentrations. The use of reference plasma, despite not completely reflecting a normal pooled plasma behavior, likely improves standardization and inter-laboratory comparisons.

Abstract
Abstract
Background Heparin-induced thrombocytopenia (HIT) is a rare complication of heparin treatments, and only a few large patient cohorts have been reported. In this study, biological and clinical data from 144 French patients with HIT were analyzed in comparison with the literature.
Methods The diagnosis of HIT was confirmed in all patients by an immunoassay combined with serotonin release assay. In the literature, only cohorts of at least 20 HIT patients published from 1992 were selected for a comparative analysis.
Results Two-thirds of patients were hospitalized in surgery and most were treated with unfractionated heparin (83.2% vs. 16.8% with low molecular weight heparin only). Thrombotic events in 54 patients (39.7%) were mainly venous (41/54). However, arterial thrombosis was more frequent after cardiac surgery (13.2% vs. 2.4% in other surgeries, p = 0.042) with a shorter recovery time (median = 3 vs. 5 days, p < 0.001). The mortality rate was lower in our series than in the 22 selected published studies (median = 6.3% vs. 15.9%). Three genetic polymorphisms were also studied and homozygous subjects FcγRIIA RR were more frequent in patients with thrombosis (37.8 vs. 18.2% in those without thrombosis, p = 0.03).
Conclusion This study shows that the mortality rate due to HIT has recently decreased in France, possibly due to earlier diagnosis and improved medical care. It also confirms the strong association between polymorphism FcγRIIA H131R and thrombosis in HIT.

Abstract
Abstract
Background
Since 2013, several international (ASRM, FIGO, ACOG) and French (ANSES) learned societies and the French National Health and Environment Plan (2015-2019) urged to take into account exposures to environmental reprotoxic substances during standard care of infertile couples and pregnant women. However perinatal health professionals hardly incorporate this recommendation into practice.
Objectives
To create a network of platforms to addressing the environmental aspects that can impact the pregnancy chances of infertile couples after ART and pregnancy outcomes.
We asked regional health authorities in France to provide funding for multidisciplinary hospital structures, in conjunction with clinical-biological reproductive health and gynecology-obstetric centers. Expertise, as well as information leaflets and risk detection tools have been shared.
Results
Platforms of counselling and prevention have been set up in the University Hospitals of Bordeaux, Marseille, Rennes, Créteil and Paris Fernand-Widal. Infertile couples and pregnant women, referred by reproductive physicians, benefit from personalized management of their domestic/professional reprotoxic exposures by addictology/tobacco, dietetics, occupational health and environmental pathology professionals. The network organizes an annual scientific day and a common database of exposure is being set up.
Conclusions
The PREVENIR (PREVENTION - ENVIRONMENT - Reproduction) network of platforms allows perinatal health professionals to refer their patients in order to optimize their chance of pregnancy through personalized and multidisciplinary care. The lifestyle changes initiated through this approach will also improve pregnancy outcomes and child health.
Key messages
A French network for the prevention and reduction of reproductive risk in infertile couples and pregnant women: the PREVENIR platforms (PREVENTION - ENVIRONMENT - Reproduction) is being established. Perinatal health professionals of multidisciplinary platforms engage into preventive actions to limit the exposure to environmental hazards during preconception and pregnancy.

Abstract
Abstract
Background
The exposure of adults of reproductive age as well as of pregnant women and children to environmental contaminants is of particular concern, as it can impact fertility, in utero development, pregnancy outcomes and child health. Although worrying, this knowledge provides an opportunity to enforce interventions during these critical reproductive/developmental times, when they may have the greatest effect. Consequently, the World Health Organization (WHO) and international societies advocate including Environmental Health (EH) in perinatal care.
Objectives
Our aim was to paint a picture of the current attitudes, representation, knowledge, and training expectations among Perinatal Health Professionals in south-eastern France.
Results
In 2017, a cross-sectional study was performed in a large panel of perinatal HPs. Quantitative and qualitative information was collected via auto-questionnaire. Questionnaires were completed by 962 participants, mainly midwives (41.1%), physicians (25.6%) and nursery nurses (11%). Indoor/outdoor air quality and endocrine disruptors were the best-mastered topics, whereas electromagnetic fields and diet gave rise to unsure responses. Overall, perinatal HPs were ill-trained and -informed about the reproductive risks linked to daily environmental exposure. HPs reported scarce knowledge, fear of patient reaction and lack of solutions as the main barriers to providing information regarding EH to the public.
Conclusions
In South-eastern France perinatal Health Professionals are eager to incorporate EH in their current practice. Our findings highlight the need to set up EH training programs focused on scientific knowledge and to provide simple messages and tips to help perinatal HPs deliver advice to populations to mitigate exposure to environmental toxicants.
Key messages
In South-eastern France perinatal Health Professionals are eager to incorporate EH in their current practice but ask for training. We are currently providing training programs combining practical sessions as well as basic and advanced scientific training adapted to the demand of medical and non-medical professional groups.

Abstract
Background Breathlessness is the prominent symptom of chronic obstructive pulmonary disease (COPD). Despite optimal therapeutic management including pharmacological and non-pharmacological interventions, many COPD patients exhibit significant breathlessness. Chronic breathlessness is defined as breathlessness that persists despite optimal treatment of the underlying disease. Because of the major disability related to chronic breathlessness, symptomatic treatments including opioids have been recommended by several authors. The prevalence of chronic breathlessness in COPD and its management in routine clinical practice have been poorly investigated. Our aim was to examine prevalence, associated characteristics and management of chronic breathlessness in patients with COPD recruited in a real-life tertiary hospital-based cohort. Methods A prospective study was conducted among 120 consecutive COPD patients recruited, in stable condition, at Nancy University Hospital, France. In parallel, 88 pulmonologists of the same geographical region were asked to respond to an on-line questionnaire on breathlessness management. Results Sixty four (53%) patients had severe breathlessness (modified Medical Research Council scale≥3), despite optimal inhaled medications for 94% of them; 40% had undergone pulmonary rehabilitation within the past 2 years. The severity of breathlessness increased with increasing airflow limitation. Breathlessness was associated with increased symptoms of anxiety, depression and with osteoporosis. No relation was found with other symptoms, exacerbation rate, or cardiovascular comorbidities. Among the patients with chronic breathlessness and Hospitalized Anxiety and/or Depression score > 10, only 25% were treated with antidepressant or anxiolytic. Among the pulmonologists 46 (52%) answered to the questionnaire and expressed a high willingness to prescribe opioids forchronic breathlessness, which contrasted with the finding that none of these patients received such treatments against breathlessness. Conclusion Treatment approaches to breathlessness and associated psychological distress are insufficient in COPD. This study highlights underuse of pulmonary rehabilitation and symptomatic treatment for breathlessness.

Abstract
We describe the clinical, hematologic and genetic characteristics of a retrospective series of 126 subjects from 64 families with hereditary xerocytosis. Twelve patients from six families carried a KCNN4 mutation, five had the recurrent p.Arg352His mutation and one had a new deletion at the exon 7-intron 7 junction. Forty-nine families carried a PIEZO1 mutation, which was a known recurrent mutation in only one-third of the cases and private sequence variation in others; 12 new probably pathogenic missense mutations were identified. The two dominant features leading to diagnosis were hemolysis that persisted after splenectomy and hyperferritinemia, with an inconstant correlation with liver iron content assessed by magnetic resonance imaging. PIEZO1-hereditary xerocytosis was characterized by compensated hemolysis in most cases, perinatal edema of heterogeneous severity in more than 20% of families and a major risk of post-splenectomy thrombotic events, including a high frequency of portal thrombosis. In KCNN4-related disease, the main symptoms were more severe anemia, hemolysis and iron overload, with no clear sign of red cell dehydration; therefore, this disorder would be better described as a ‘Gardos channelopathy’. These data on the largest series to date indicate that PIEZO1-hereditary xerocytosis and Gardos channelopathy are not the same disease although they share hemolysis, a high rate of iron overload and inefficient splenectomy. They demonstrate the high variability in clinical expression as well as genetic bases of PIEZO1-hereditary xerocytosis. These results will help to improve the diagnosis of hereditary xerocytosis and to provide recommendations on the clinical management in terms of splenectomy, iron overload and pregnancy follow-up.

Abstract
Cerium dioxide nanoparticles (CeO2NP) are widely used for industrial purposes, as in diesel, paint, wood stain and as potential therapeutic applications. The Organization for Economic Cooperation and Development included CeO2NP in the priority list of nanomaterials requiring urgent evaluation. As metal nanoparticles can cross the blood-testis barrier, CeO2NP could interact with spermatozoa. The genotoxicity of CeO2NP was demonstrated in vitro on human cell lines and mouse gametes. However, the effects of CeO2NP on human spermatozoa DNA remain unknown. We showed significant DNA damage induced in vitro by CeO2NP on human spermatozoa using Comet assay. The genotoxicity was inversely proportional to the concentration (0.01 to 10 mg·L-1). TEM showed no internalization of CeO2NP into the spermatozoa. This study shows for the first time that in vitro exposure to very low concentrations of cerium dioxide nanoparticles can induce significant DNA damage in human spermatozoa. These results add new and important insights regarding the reproductive toxicity of priority nanomaterials, which require urgent evaluation.

Abstract
SummaryCathepsin G (Cath G), a serine-protease found in neutrophils, has been reported to have effects that could either facilitate or impede coagulation. Thrombin generation (CAT method) was chosen to study its overall effect on the process, at a plasma concentration (240 nM) observed after neutrophil activation. Coagulation was triggered by tissue factor in the presence of platelets or phospholipid vesicles. To help identify potential targets of Cath G, plasma depleted of clotting factors or of inhibitors was used. Cath G induced a puzzling combination of two diverging effects of varying intensities depending on the phospholipid surface provided: accelerating the process under the three conditions (shortened clotting time by up to 30%), and impeding the process during the same thrombin generation time-course since thrombin peak and ETP (total thrombin potential) were decreased, up to 45% and 12%, respectively, suggestive of deficient prothrombinase. This is consistent with Cath G working on at least two targets in the coagulation cascade. Our data indicate that coagulation acceleration can be attributed neither to platelet activation and nor to activation of a clotting factor. When TFPI (tissue factor pathway inhibitor) was absent, no effect on lag time was observed and the anticoagulant activity of TFPI was decreased in the presence of Cath G. Consistent with the literature and the hypothesis of deficient prothrombinase, experiments using Russel’s Viper Venom indicate that the anticoagulant effect can be attributed to a deleterious effect on factor V. The clinical relevance of these findings deserves to be studied.

Abstract
Our objective was to optimize the CA technique on mammal embryos. MATERIALS AND METHODS 1000 frozen 2-cell embryos from B6CBA mice were used. Based on a literature review, and after checking post-thaw embryo viability, the main outcome measures included: 1) comparison of the embryo recovery rate between 2 CA protocols (2 agarose layers and 3 agarose layers); 2) comparison of DNA damage by the CA on embryos with (ZP+) and without (ZP-) zona pellucida; and 3) comparison of DNA damage in embryos exposed to 2 genotoxic agents (H2O2 and simulated sunlight irradiation (SSI)). DNA damage was quantified by the % tail DNA. RESULTS 1) The recovery rate was 3,3% (n=5/150) with the 2 agarose layers protocol and 71,3% (n=266/371) with the 3 agarose layers protocol. 2) DNA damage did not differ statistically significantly between ZP- and ZP+ embryos (12.60±2.53% Tail DNA vs 11.04±1.50 (p=0.583) for the control group and 49.23±4.16 vs 41.13±4.31 (p=0.182) for the H2O2 group); 3) H2O2 and SSI induced a statistically significant increase in DNA damage compared with the control group (41.13±4.31% Tail DNA, 36.33±3.02 and 11.04±1.50 (p<0.0001)). The CA on mammal embryos was optimized by using thawed embryos, by avoiding ZP removal and by the adjunction of a third agarose layer.

Abstract
Beside cytotoxic drugs, other drugs can impact men's fertility through various mechanisms. Via the modification of the hypothalamic-pituitary-gonadal axis hormones or by non-hormonal mechanisms, drugs may directly and indirectly induce sexual dysfunction and spermatogenesis impairment and alteration of epididymal maturation. This systematic literature review summarizes existing data about the negative impact and associations of pharmacological treatments on male fertility (excluding cytotoxic drugs), with a view to making these data more readily available for medical staff. In most cases, these effects on spermatogenesis/sperm maturation/sexual function are reversible after the discontinuation of the drug. When a reprotoxic treatment cannot be stopped and/or when the impact on semen parameters/sperm DNA is potentially irreversible (Sulfasalazine Azathioprine, Mycophenolate mofetil and Methotrexate), the cryopreservation of spermatozoa before treatment must be proposed. Deleterious impacts on fertility of drugs with very good or good level of evidence (Testosterone, Sulfasalazine, Anabolic steroids, Cyproterone acetate, Opioids, Tramadol, GhRH analogues and Sartan) are developed.

Abstract
INTRODUCTION The osmotic fragility (OF) test was a central test for the diagnosis of hereditary red blood cell (RBC) disorders (mostly hereditary spherocytosis (HS), but thalassaemia as well). Nowadays although the traditional multitubes method has lost a prominent place, many laboratories still perform such a laboured test, despite the lack of standardization. In fact, the evaluation of OF may offer an inexpensive screening for RBC disorders. We present a new semi-automatic device, allowing the continuous recording of OF, by an updated dialysis method. METHODS Repeatability, stability over time, influence of the anticoagulant were evaluated among a population of healthy blood donors. The test was then performed among patients presenting inherited RBC disorders (HS or haemoglobinopathies) where OF is typically altered. RESULTS Repeatability was excellent; the parameters were greatly influenced by the nature of the anticoagulant and interestingly appeared stable for 48 h. Patients with RBC disorders displayed the expected profile in regard with their disease: patients with HS all presented an increased OF while patients with haemoglobinopathy displayed resistant profiles. CONCLUSION The device offers a substantial improvement in terms of standardization and consistency of the results and may offer a considerable gain for general laboratories.

Abstract
OBJECTIVES To study the social dimension of age-related female infertility through an analysis of three key themes: the personal life histories of infertile women over 40 years of age; representations of age and the desire to become pregnant after age 40; opinions of French legislations framing Assisted Reproductive Technologies, age limits, egg donation, and egg freezing for non-medical reasons. METHODS This qualitative sociological study was based on semi-structured interviews with infertile women over age 40 going through fertility treatments. The interviews contained three parts: personal and relationship histories; experiences related to age; opinions related to French legislation. RESULTS Twenty-three interviews were conducted; each lasting between 90 to 120minutes. Far from having similar life histories, the women interviewed had very different backgrounds leading to their desire for a pregnancy after 40 years of age. From the beginning of their fertility treatments, they perceived a "race against the clock". This feeling of urgency accompanied their experiences and was related to the desire to not be too old for their future child. The women interviewed were mainly in favor of loosening French bioethical laws in order to avoid the need to travel abroad to pursue fertility treatments. CONCLUSION The profiles studied attest to a growing gap between biological and biographical temporalities, as well as an inability of women to reduce their desire for a child. Faced with this disparity, egg donation and egg freezing were seen as practical solutions.

Abstract
Treatment of stroke, especially during the first hours or days, is still lacking. S-nitrosoglutathione (GSNO), a cerebroprotective agent with short life time, may help if administered early with a sustain delivery while avoiding intensive reduction in blood pressure. We developed in situ forming implants (biocompatible biodegradable copolymer) and microparticles (same polymer and solvent emulsified with an external oily phase) of GSNO to lengthen its effects and allow cerebroprotection after a single subcutaneous administration to Wistar rats. Arterial pressure was recorded for 3 days (telemetry, n = 14), whole-blood platelet aggregation up to 13 days (aggregometry, n = 58), and neurological score, cerebral infarct size and edema volume for 2 days after obstruction of the middle cerebral artery by autologous blood clots (n = 30). GSNO-loaded formulations (30 mg/kg) induced a slighter and longer hypotension (-10 vs. -56 ± 6 mmHg mean arterial pressure, 18 h vs. 40 min) than free GSNO at the same dose. The change in pulse pressure (-50%) lasted even up to 42 h for microparticles. GSNO-loaded formulations (30 mg/kg) prevented the transient 24 h hyper-aggregability observed with free GSNO and 7.5 mg/kg-loaded formulations. When injected 2 h after stroke, GSNO-loaded microparticles (30 mg/kg) reduced neurological score at 24 (-62%) and 48 h (-75%) vs. empty microparticles and free GSNO 7.5 mg/kg and, compared to free GSNO, divided infarct size by 10 and edema volume by 8 at 48 h. Corresponding implants reduced infarct size and edema volume by 2.5 to 3 times. The longer (at least 2 days) but slight effects on arterial pressures show sustained delivery of GSNO-loaded formulations (30 mg/kg), which prevent transient platelet hyper-responsiveness and afford cerebroprotection against the consequences of stroke. In conclusion, in situ GSNO-loaded formulations are promising candidates for the treatment of stroke.

Abstract
Alteration of sperm parameters related to occupational exposures is the subject of several studies, often on a case-control approach. The study populations usually comprise men consulting in infertility clinics for couple infertility. The objective of this review is to identify, from these case-control studies, the main occupational factors that may be associated with altered sperm parameters. We selected 13 articles in the PubMed database. Participation in these studies varied from 61 to 2619 subjects, with great methodological heterogeneity, particularly in the characterization of exposure. The main occupations that appear significantly associated with a risk of altered sperm parameters are workmen, painters, farmers, welders, plumbers and technicians. When analysis focuses on occupational exposures, a significant result is reported for solvents, heavy metals, heat, vibrations and non-ionizing radiation. None of the selected studies has found a link with exposure to pesticides.

Abstract
OBJECTIVES To assess midwifery students' knowledge in the field of female fertility and to study their decision if they had diagnosis of diminished ovarian reserve (DOR). SUBJECTS AND METHODS A prospective observational study by self-administered questionnaire was conducted among female midwifery students of seven French schools from June to December 2013. The questionnaire had three parts: (1) questions designed to gather information on the study population; (2) a questionnaire consisting of 10 items to test knowledge about female fertility and ovarian reserve; (3) a self-administered questionnaire simulating a DOR diagnosis and quantifying the decision that students would make using a Likert scale of 5 points. RESULTS The participation rate was 72.5% (n=285/393). The average age was 22, 6 years±1.9. Among the 285 participants, the ovarian reserve concept was known by 93% of them (n=265) thanks to the midwifery studies (77%, n=204), the media (9%, n=24) and other sources of information. In total, 83.5% of midwifery students (n=238) were interested in assessing their ovarian reserve, and 48.3% of them were interested in evaluating it immediately (n=115). Among midwifery students, 22.5% of them (n=64) reported that female fertility began to decline from the age of 35 years old; 85.6% (n=244) thought that in vitro fertilization allowed women to conceive if fertility is related to a diminished ovarian reserve; 43.9% (n=125) answered that physical activity and a healthy diet had a beneficial effect on the ovarian reserve. If a DOR was diagnosed to them, 76.8% of students (n=219) would be likely to conceive their first child earlier than expected. Among them, 57.9% (n=165) would agree to have oocyte freezing in this context. CONCLUSION This study is the first in France that assessed students' knowledge on fertility. We observed: (1) gaps and misconceptions about female fertility despite a medical training in midwifery students; (2) a belief that in vitro fertilization is effective to overcome infertility related to age; (3) that some of these young students would be favorable to oocyte social freezing (technique not allowed in France); (4) that an adequate information on the decrease of fertility with age could lead some students to anticipate their first pregnancy. Specific information regarding the decrease of fertility with age should be offered to all reproductive-aged young women.
