ABSTRACT
Uterus transplantation is a new possibility for women suffering from absolute uterine infertility to become pregnant and have children. In the case of a deceased donor, a list of exclusion criteria is defined to ensure the high quality of the uterus graft. This study evaluates the number of potentially available uterus grafts based on the pre-defined exclusion criteria in a national deceased donor multi-organ donation program in France. We analyzed the data reported in the CRISTAL database regarding all women aged 18 to 60 on whom organ procurement was performed between 2014 and 2019. Potential deceased women donors were classified into three categories: very ideal donor, ideal donor, and expanded criteria donor. Between 2014 and 2019, 4544 women underwent organ procurement. Using the very ideal donor, ideal donor, and expanded criteria donor classification, we found that, respectively, only 124, 264, and 936 donors were potentially eligible for UTx. This represents 2.8 per million people (PMP) very ideal donors, 3.8 PMP ideal donors, 8.6 PMP expanded criteria donors (ECDs). The restricted number of grafts requires a complementary strategy of living and deceased donors to meet the demand of all women with AUI.
ABSTRACT
INTRODUCTION: In 2015, France authorised controlled donation after circulatory death (cDCD) according to a nationally approved protocol. The aim of this study is to provide an overview from the perspective of critical care specialists of cDCD. The primary objective is to assess how the organ donation procedure affects the withdrawal of life-sustaining therapies (WLST) process. The secondary objective is to assess the impact of cDCD donors' diagnoses on the whole process. MATERIAL AND METHODS: This 2015-2019 prospective observational multicentre study evaluated the WLST process in all potential cDCD donors identified nationwide, comparing 2 different sets of subgroups: 1- those whose WLST began after organ donation was ruled out vs. while it was still under consideration; 2- those with a main diagnosis of post-anoxic brain injury (PABI) vs. primary brain injury (PBI) at the time of the WLST decision. RESULTS: The study analysed 908 potential cDCD donors. Organ donation remained under consideration at WLST initiation for 54.5% of them with longer intervals between their WLST decision and its initiation (2 [1-4] vs. 1 [1-2] days, P < 0.01). Overall, 60% had post-anoxic brain injury. Time from ICU admission to WLST decision was longer for primary brain injury donors (10 [4-21] vs. 6 [4-9] days, P < 0.01). Median time to death (agonal phase) was 15 [15-20] min. CONCLUSIONS: French cDCD donors are mostly related to post-anoxic brain injury. The organ donation process does not accelerate WLST decision but increases the interval between the WLST decision and its initiation.

Rationale: Previous studies have shown that a lung-protective strategy, which aims at minimizing ventilator-induced lung injury (with low Vt/high positive end-expiratory pressure as the main pillars), in selected potential organ donors after brain death increased lung eligibility and procurement.Objectives: This prospective nationwide cohort study aimed to evaluate the impact of lung-protective ventilation (PV) in nonselected donors on lung procurement and recipient survival after lung transplantation.Methods: We included all reported donors aged 18-70 years after brain death without a lung recovery contraindication and with at least one organ recovered between January 2016 and December 2017. PV was defined as Vt ≤8 ml/kg predicted body weight and positive end-expiratory pressure ≥8 cm H2O. The association between PV at the time of lung proposal (T1) and lung procurement was determined by multivariable logistic regression stratified by propensity score quintile to account for PV and non-PV group differences in baseline characteristics. We studied 1-year survival of recipients from donors with or without PV at T1.Measurements and Main Results: Of 1,626 included lung donors, 1,109 (68%) had at least one lung proposed; 678 (61%) of these had at least one lung recovered. At T1, only 25.6% of donors with at least one lung proposed for lung transplantation were ventilated with a protective strategy. For donors with a lung proposal, the probability of lung procurement was increased with PV at T1 (odds ratio, 1.43; 95% confidence interval [CI], 1.03-1.98; P = 0.03). One-year survival did not differ between recipients of lungs from donors with and without PV (82.7%, 95% CI 76.0-87.8% vs. 82.3%, 95% CI 78.5-85.4%; P = 0.94).Conclusions: The use of lung PV in nonselected donors may increase lung procurement. One-year survival did not differ between recipients of lungs from donors with PV or from those without PV.

BACKGROUND: In France, the need for continuous monitoring of transplant center performance has recently become apparent. Cumulative sum (CUSUM) monitoring of transplantation is already been used to monitor transplant outcomes in the United Kingdom and in the United States. Because CUSUM monitoring can be applied by different methods, the objective was to assess and compare the performance of different CUSUM methods for detecting higher than expected (ie, excessive) graft failure rates. METHODS: Data come from the French transplant registry. Lung and kidney transplants in 2011-2013 constituted the control cohort, and those in 2014-2016 the observed cohort. The performance of CUSUM monitoring, according to center type and predefined control limits, was measured by simulation. The outcome monitored was 3-month graft failure. RESULTS: In a low-volume center with a low failure rate, 3 different types of control limits produced successful detection rates of excessive graft failures of 15%, 62%, and 73% and false alarm rates of 5%, 40%, and 52%, with 3, 1, and 1 excess failures necessary before a signal occurred. In a high-volume center with a high failure rate, successful detection rates were 83%, 93%, and 100% and false alarm rates were 5%, 16%, and 69%, with 6, 13, and 17 excess failures necessary before a signal occurred. CONCLUSIONS: CUSUM performances vary greatly depending on the type of control limit used. A new control limit set to maximize specificity and sensitivity of detection is an appropriate alternative to those commonly used. Continued attention is necessary for centers with characteristics making it difficult to obtain adequate sensitivity or sufficiently prompt response.

WHY THE COHORT WAS SET UP?: CONSTANCES is a general-purpose cohort with a focus on occupational and environmental factors. COHORT PARTICIPANTS: CONSTANCES was designed as a randomly selected sample of French adults aged 18-69â years at inception; 200â 000 participants will be included. DATA COLLECTION PHASES: At enrolment, the participants are invited to complete questionnaires and to attend a health screening centre (HSC) for a health examination. A biobank will be set up. The follow-up includes an yearly self-administered questionnaire, a periodic visit to an HSC and linkage to social and national health administrative databases. MAIN TYPES OF DATA COLLECTED: Data collected for participants include social and demographic characteristics, socioeconomic status, life events and behaviours. Regarding occupational and environmental factors, a wealth of data on organisational, chemical, biological, biomechanical and psychosocial lifelong exposure, as well as residential characteristics, are collected at enrolment and during follow-up. The health data cover a wide spectrum: self-reported health scales, reported prevalent and incident diseases, long-term chronic diseases and hospitalisations, sick-leaves, handicaps, limitations, disabilities and injuries, healthcare usage and services provided, and causes of death. CONTROL OF SELECTION EFFECTS: To take into account non-participation and attrition, a random cohort of non-participants was set up and will be followed through the same national databases as participants. DATA ACCESS: Inclusions begun at the end of 2012 and more than 110â 000 participants were already included by September 2016. Several projects on occupational and environmental risks already applied to a public call for nested research projects.

The aim of this study was to explore the achievement of parenthood 8 years after starting IVF, considering multiple pathways to parenthood during and after IVF treatment. Medical data on 6507 couples who began IVF between 2000 and 2002 were obtained from the databases of eight French IVF centres. Information on long-term outcome was available for participants in the 2008-2010 postal survey. Multiple imputation methods were used to account for missing data. Eight years after starting IVF, 71% (95% CI 69 to 74) of treated couples had a child. This included 41% live births after IVF in the IVF centre, 7% live births after another treatment or after IVF in another centre, 12% live births after spontaneous conception and 11% adoptions. This study provides a longitudinal overview of paths to parenthood among couples successfully and unsuccessfully treated by IVF. These results should give hope to infertile couples as seven out of 10 couples finally became parents. However, IVF is not the only path to parenthood, and couples should be informed of the other possible avenues.

Numerous studies have found agricultural workers, including farmers, at elevated risk of suicide, and socioeconomic conditions have been suggested as one of the important determinants of this mortality cause. The real agricultural income per worker in Europe increased steadily from 2005 to 2007 and then fell by 1.8% in 2008 and by 11.6% in 2009. This drop was particularly pronounced in France. Repeated cross-sectional studies were conducted to investigate suicide mortality rates among French farmers in 2007-2009. The study population included all French farmers enrolled yearly in the compulsory Agricultural Social Security and Health Insurance (CCMSA). Most of the mean of 500,164 subjects per year were men (68%). National cause-specific mortality rates were used to calculate standardized mortality ratios (SMRs) and associated 95% confidence intervals (95% CIs) for both genders and for each of the 3 years. During the 3-year study period, 2,769 men and 997 women died. Suicide accounted for 417 of the men's (15%) and 68 of the women's (6.8%) deaths. Hanging was the most frequent method of suicide for both. Compared with the general population, the increased rate of suicide deaths among male farmers was 28% in 2008 and 22% in 2009. This increased rate was particularly high among those aged 45-54 years (31%) and 55-64 years (47%) in 2008 (and in the 55-64-year-old group in 2009 (64%). Two specific types of farming activity were associated with increased suicide mortality rates in both 2008 and 2009: dairy cattle farming (SMR = 1.56 [95% CI: 1.09-2.15] and SMR=1.47 [95% CI: 1.01-2.04]) and beef cattle farming (SMR = 2.27 [95% CI: 1.59-3.10] and SMR = 1.57 [95% CI: 1.01-2.27]). These results may be useful for a better understanding of the situation from an epidemiological standpoint and for improving suicide prevention policies in this particular population.

OBJECTIVES: To show how reweighting can correct for unit nonresponse bias in an occupational health surveillance survey by using data from administrative databases in addition to classic sociodemographic data. STUDY DESIGN AND SETTING: In 2010, about 10,000 workers covered by a French health insurance fund were randomly selected and were sent a postal questionnaire. Simultaneously, auxiliary data from routine health insurance and occupational databases were collected for all these workers. To model the probability of response to the questionnaire, logistic regressions were performed with these auxiliary data to compute weights for correcting unit nonresponse. Corrected prevalences of questionnaire variables were estimated under several assumptions regarding the missing data process. The impact of reweighting was evaluated by a sensitivity analysis. RESULTS: Respondents had more reimbursement claims for medical services than nonrespondents but fewer reimbursements for medical prescriptions or hospitalizations. Salaried workers, workers in service companies, or who had held their job longer than 6 months were more likely to respond. Corrected prevalences after reweighting were slightly different from crude prevalences for some variables but meaningfully different for others. CONCLUSION: Linking health insurance and occupational data effectively corrects for nonresponse bias using reweighting techniques. Sociodemographic variables may be not sufficient to correct for nonresponse.

OBJECTIVE: To examine the associations between psychosocial exposures at work and depressive symptoms by using two independent French national databases. METHODS: A job-exposure matrix of psychosocial work exposures was constructed from data collected by the national medical monitoring of occupational risks survey in 2003. Depressive symptoms came from the 2002 to 2003 decennial health survey. Data were linked by age, occupational group, and economic activity. RESULTS: The crude and adjusted results showed small but significant and systematic associations between job strain and depressive symptoms among men. These associations were much weaker for psychological demands and decision latitude. No statistical associations were observed among women. CONCLUSION: The results suggest that, among men, using independent data on exposure and health, there is a robust association between job strain and depressive symptoms. They contribute to the debate about the causal nature of associations between psychosocial exposures at work and mental health.

INTRODUCTION: The aim of this study is to describe the associations between depressive symptoms and some working conditions according to broad occupational categories in France. METHODS: These data came from the decennial health survey conducted in 2003 in France by the National Institute for Statistics and Economics Studies (6,082 men, 5,521 women). The data collected included: depressive symptoms (Center for Epidemiological Studies-Depression Scale), psychosocial factors at work and potential confounding factors. RESULTS: Associations between psychosocial work factors and depressive symptoms varied, according to occupational category and sex. Time pressure was significantly associated with depressive symptoms in the less advantaged occupational categories. The lack of job control was associated with depressive symptoms only in managers and associate professionals and technicians. Only low social support was systematically associated with depressive symptoms, regardless of occupational category. CONCLUSION: These results should be taken into account to adapt strategies of mental health disorders prevention at work, for a better efficacy.

BACKGROUND: The objective is to study the relations between depressive symptoms and atypical jobs in the working population in France and to determine if these associations might be linked with psychosocial and organizational constraints. METHODS: The data come from the 2003 Decennial health survey and concern 11,895 workers. Depressive symptoms were measured by the CES-D scale. Atypical jobs were defined by employment status (fixed-term or temporary job contract, permanent job contract, self-employed) and by part-time work during working life (involuntary or chosen). Working conditions related to atypical hours and psychosocial factors were also studied. RESULTS: For both sexes, involuntary part-time work was associated with a higher frequency of depressive symptoms, but part-time work by choice was not. Fixed-term contracts were associated with depressive symptoms only in women. All of these associations persisted after adjustment for psychosocial and organizational factors. CONCLUSION: The associations between atypical jobs and depressive symptoms differ for job status according to sex and do not seem to be associated with the worst psychosocial working conditions. The interpretation of these results is nonetheless limited in part by the cross-sectional nature of the survey.

The primary mission of the Department of Occupational Health of the French Institute for Public Health Surveillance (InVS) is to monitor health in relationship to occupational activities. Data produced in other fields can contribute to its mission in particular data from public health surveys carried out among the general population in France. A study on occupational and mental health using data from the 2002-2003 Insee Decennial Health Survey serves as an exemplary case to illustrate this process. The data analysis according to job type shows important differences and variations in the prevalence of depressive symptoms within social groups and sectors of professional activity. Despite some limitations, the use of major public health surveys provides interesting assets and benefits to complement surveillance tools for occupational risks.

OBJECTIVE: The aim of this study was to compare the quality of life (QOL) of high-risk breast cancer patients included in a randomized clinical trial (PEGASE 01) comparing conventional chemotherapy versus adding an additional high-dose chemotherapy (HDC) cycle with blood stem cell support. METHODS: A total of 314 patients were included in the clinical trial. QOL evaluations were available for 199 patients. QOL was assessed over a 1-year follow-up period, using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire C-30. The results were analyzed using a linear mixed-effects model. RESULTS: Toxicity of HDC has a strong negative impact on patients' QOL during the treatment phase. This negative impact tended to last longer in the HDC group, as for most of the QLQ-C30 scales, the QOL scores of HDC patients tend to improve at a slower rate than that of patients receiving standard chemotherapy. In particular, physical functioning remains deteriorated 1 year after inclusion for HDC patients comparatively to conventional chemotherapy patients (85.99 vs. 76.65, P = 0.021), and the pain score was still higher in the HDC group at that time (28.32 vs. 15.97, P = 0.004). CONCLUSION: HDC has a negative impact on QOL even after treatment phase. In the absence of an overall survival benefit of using HDC for high-risk breast cancer patients, QOL studies with a longer follow-up play an important role in informing the complex trade-off implied by HDC between higher toxicity, reduced risk of relapse, and QOL decrease after the active phase of treatment.

INTRODUCTION: The Decisional Conflict Scale (DCS, 16 items, 5 dimensions) designed to measure the level of decisional conflict experienced by patients making health care decisions has not yet been validated in French. METHODS: A national sample of French cancer patients (n=644) facing the decision to undergo BRCA genetic testing was tested for this purpose, including a control group and an experimental group who had received an information booklet. Reliability and criterion validity were investigated. To check the validity of the factors selected, an exploratory factor analysis was then conducted, followed by confirmatory factor analyses. RESULTS: Reliability was satisfactory (alpha=0.913). Women who definitely wanted to undergo genetic testing showed significantly lower DCS scores than uncertain women (p<0.001). Exploratory factor analysis suggested an optimal 4-dimensional model. In the control group, confirmatory factor analyses showed that the French model was more accurate than the original one. When the decision-making conflicts decreased (in the experimental group), both models yielded only fairly accurate indices. CONCLUSION: The French version of the DCS was found to give a reliable overall score. However, special care should be taken when using the individual subscores. In addition, it is necessary to take into account the context in which the decision-making occurs.
