Abstract
Achromobacter spp. are opportunistic pathogens of environmental origin increasingly isolated in patients with underlying conditions like cystic fibrosis (CF). Despite recent advances, their virulence factors remain incompletely studied, and siderophore production has not yet been investigated in this genus. The aim of this study was to evaluate the production of siderophores in a large collection of Achromobacter spp. and evaluate the variability according to the origin of the strain and species. A total of 163 strains were studied, including 128 clinical strains (CF and non-CF patients) and 35 strains of environmental origin. Siderophores were quantified by the liquid chrome azurol-sulphonate assay. Species were identified by nrdA gene-based phylogeny. Strains were assigned to 20 species, with Achromobacter xylosoxidans being the most represented (51.5% of strains). Siderophore production was observed in 72.4% of the strains, with amounts ranging from 10.1% to 90% siderophore units. A significantly higher prevalence of siderophore-producing strains and greater production of siderophores were observed for clinical strains compared with strains of environmental origin. Highly variable observations were made according to species: A. xylosoxidans presented unique characteristics (one of the highest prevalence of producing strains and highest amounts produced, particularly by CF strains). Siderophores are important factors for bacterial growth commonly produced by members of the Achromobacter genus. The significance of the observations made during this study must be further investigated. Indeed, the differences observed according to species and the origin of strains suggest that siderophores may represent important determinants of the pathophysiology of Achromobacter spp. infections and also contribute to the particular epidemiological success of A. xylosoxidans in human infections. IMPORTANCE Achromobacter spp. are recognized as emerging opportunistic pathogens in humans with various underlying diseases, including cystic fibrosis (CF). Although their pathophysiological traits are increasingly studied, their virulence factors remain incompletely described. Particularly, siderophores that represent important factors of bacterial growth have not yet been studied in this genus. A population-based study was performed to explore the ability of members of the Achromobacter genus to produce siderophores, both overall and in relevant subgroups (Achromobacter species; strain origin, either clinical-from CF or non-CF patients-or environmental). This study provides original data showing that siderophore production is a common trait of Achromobacter strains, particularly observed among clinical strains. The major species, Achromobacter xylosoxidans, encompassed both one of the highest prevalence of siderophore-producing strains and strains producing the largest amounts of siderophores, particularly observed for CF strains. These observations may represent additional advantages accounting for the epidemiological success of this species.

Abstract
Oftentimes ignored or infrequently expressed, some transgender persons harbor a desire for parenthood. Given the evolution of medical techniques and the enacting of legislative reforms, it is henceforth possible to propose fertility preservation strategies in the overall context of gender transidentity. During the "female to male" (FtM) transition pathway, androgen therapy has an impact on gonadic function, generally inducing blockage of the ovarian function, with amenorrhea. Even though these events may be reversed on cessation of treatment, the possible long-term effects on future fertility and on the health of children yet to be born are little known. Moreover, transition surgeries definitively compromise the possibility of pregnancy insofar as they involve bilateral adnexectomy and/or hysterectomy. Options for fertility preservation in the framework of FtM transition are premised on cryopreservation of oocytes and/or ovarian tissue. In a comparable manner, even though relevant documentation is lacking, hormonal treatments for persons transitioning from male to female (MtF) can have an impact on future fertility. In the event of surgery involving bilateral orchidectomy in which spermatozoid cryopreservation has not been carried out, fertility is definitively impossible. In both cases and under present-day legislation, numerous legal and regulatory barriers render highly problematic the reutilization of cryopreserved gametes. Given these different constraints, it is indispensable to closely supervise these types of treatment by proposing psychological support.

Abstract
INTRODUCTION The multiorgan impact of moderate to severe coronavirus infections in the post-acute phase is still poorly understood. We aimed to evaluate the excess burden of multiorgan abnormalities after hospitalisation with COVID-19, evaluate their determinants, and explore associations with patient-related outcome measures. METHODS In a prospective, UK-wide, multicentre MRI follow-up study (C-MORE), adults (aged ≥18 years) discharged from hospital following COVID-19 who were included in Tier 2 of the Post-hospitalisation COVID-19 study (PHOSP-COVID) and contemporary controls with no evidence of previous COVID-19 (SARS-CoV-2 nucleocapsid antibody negative) underwent multiorgan MRI (lungs, heart, brain, liver, and kidneys) with quantitative and qualitative assessment of images and clinical adjudication when relevant. Individuals with end-stage renal failure or contraindications to MRI were excluded. Participants also underwent detailed recording of symptoms, and physiological and biochemical tests. The primary outcome was the excess burden of multiorgan abnormalities (two or more organs) relative to controls, with further adjustments for potential confounders. The C-MORE study is ongoing and is registered with ClinicalTrials.gov, NCT04510025. FINDINGS Of 2710 participants in Tier 2 of PHOSP-COVID, 531 were recruited across 13 UK-wide C-MORE sites. After exclusions, 259 C-MORE patients (mean age 57 years [SD 12]; 158 [61%] male and 101 [39%] female) who were discharged from hospital with PCR-confirmed or clinically diagnosed COVID-19 between March 1, 2020, and Nov 1, 2021, and 52 non-COVID-19 controls from the community (mean age 49 years [SD 14]; 30 [58%] male and 22 [42%] female) were included in the analysis. Patients were assessed at a median of 5·0 months (IQR 4·2-6·3) after hospital discharge. Compared with non-COVID-19 controls, patients were older, living with more obesity, and had more comorbidities. Multiorgan abnormalities on MRI were more frequent in patients than in controls (157 [61%] of 259 vs 14 [27%] of 52; p<0·0001) and independently associated with COVID-19 status (odds ratio [OR] 2·9 [95% CI 1·5-5·8]; padjusted=0·0023) after adjusting for relevant confounders. Compared with controls, patients were more likely to have MRI evidence of lung abnormalities (p=0·0001; parenchymal abnormalities), brain abnormalities (p<0·0001; more white matter hyperintensities and regional brain volume reduction), and kidney abnormalities (p=0·014; lower medullary T1 and loss of corticomedullary differentiation), whereas cardiac and liver MRI abnormalities were similar between patients and controls. Patients with multiorgan abnormalities were older (difference in mean age 7 years [95% CI 4-10]; mean age of 59·8 years [SD 11·7] with multiorgan abnormalities vs mean age of 52·8 years [11·9] without multiorgan abnormalities; p<0·0001), more likely to have three or more comorbidities (OR 2·47 [1·32-4·82]; padjusted=0·0059), and more likely to have a more severe acute infection (acute CRP >5mg/L, OR 3·55 [1·23-11·88]; padjusted=0·025) than those without multiorgan abnormalities. Presence of lung MRI abnormalities was associated with a two-fold higher risk of chest tightness, and multiorgan MRI abnormalities were associated with severe and very severe persistent physical and mental health impairment (PHOSP-COVID symptom clusters) after hospitalisation. INTERPRETATION After hospitalisation for COVID-19, people are at risk of multiorgan abnormalities in the medium term. Our findings emphasise the need for proactive multidisciplinary care pathways, with the potential for imaging to guide surveillance frequency and therapeutic stratification.

Abstract
OBJECTIVE Describe the "patient experience" regarding care provided during the surgical management of a loss of pregnancy in the first trimester and identify the factors influencing this experience. MATERIAL AND METHODS It is an observational prospective study conducted in two type III, academic, maternity wards in Lyon, France, carrying out 8,500 deliveries per year. Adult female patients, having undergone a suction curettage for a loss of pregnancy in the first trimester from 24 December 2020 to 13 June 2021 were inculded. The "patient experience" was assessed using the 15 questions of the Picker Patient Experience (PPE-15) questionnaire, and research was conducted on factors influencing the patient experience. The main outcome was the percentage of patients reporting a problem in response to at least one of the PPE-15 questions. RESULTS 58 out of 79 patients (73% CI [62-83]) reported at least one problem with their care. The largest proportion of problems was raised in question about "Opportunity for family/loved ones to talk to the doctor" (76% CI [61-87]). The lowest proportion of problems was raised in question about "Treated with respect and dignity" (8% CI [3-16]). No factors influencing the patient experience were identified. DISCUSSION Almost three out of four patients reported a problem in the experience as a patient. The main areas of improvement reported by patients were the participation of their family/relatives and the emotional support provided by the healthcare team. TWEETABLE ABSTRACT Better communication with patient families and emotional support could improve patient experience during the surgical management of a loss of pregnancy in the first trimester.

Abstract
The evolution of medical techniques as well as legislative changes currently allow to propose fertility preservation strategies in the context of transidentity. During "female to male" transition, androgen therapy has an impact on gonadal function since it usually induces a blockage of ovulation with amenorrhea. Although this effect is reversible when treatment is stopped, the possible long-term effects of testosterone treatment on future fertility or health of future children are poorly known. In addition, transitional surgeries definitely compromise fecundity when they include bilateral ovariectomy and/or hysterectomy. Yet, although long ignored or poorly expressed, the desire for parenthood is a reality in transgender men. Fertility preservation options in FtM transition rely on oocyte or ovarian tissue cryopreservation. The purpose of this review is to provide an overview of the literature regarding fertility preservation in transgender men. Although series remain limited, the increase in the number of recently published articles reflects the interest in improving the management of fertility issues in transgender men.

Abstract
Baby-led weaning (BLW), proposed as a new form of complementary feeding, has emerged as a real trend phenomenon in the media. Infants are seated at the family table from the age of 6 months, facing the foods they grab and bring to their mouth: they decide which foods they want to eat and what amount. The consumption of mashed foods and the use of a spoon are totally discouraged. BLW is increasingly used in nurseries and centers of young children. A bibliographic search carried out between 2000 and 2021 found 423 articles, of which 38 were selected. The clinical studies selected are 11 cross-sectional observational studies and two randomized controlled studies. BLW promotes breastfeeding, the early introduction of morsels, the respect of the child's appetite, the use of unprocessed foods, and the choice of "homemade" and friendliness. These benefits can nonetheless be reached with usual complementary feeding (SCF), according to current recommendations. Other benefits are claimed without scientific evidence such as easier achievement of dietary complementary feeding and an optimal growth with prevention of excess weight gain. BLW has some obvious downsides. The infant may not get enough energy, iron, zinc, vitamins, and other nutrients, or too much protein, saturated fat, salt, or sugar. The risk of choking, which must be distinguished from the physiological gagging reflex, has not been ruled out by scientific studies. Currently, the Nutrition Committee of the French Pediatric Society considers that the data published to date in terms of benefits and risks of BLW do not lend themselves to advice for this practice in preference over SCF carried out according to current recommendations.

Abstract
BACKGROUND Radiopharmaceuticals preparation unit, such as every aseptic preparation units, are strictly monitored in terms of microbiological contamination. Despite all biocontamination control procedures, our radiopharmacy unit faced repeated environnmental contamination by Achromobacter spp which necessitated a large environmental investigation. METHOD Microbiological controls were carried out using Count Tact agars (Biomérieux) for flat surfaces, dry swabbing for hard to reach areas and containers were filled with a sterile water solution (then filtrated on 0.45µm membrane and seeded). Microbiological identification was performed by mass spectrometry (MALDI-TOF-MS, Brucker) on each positive sample. RESULTS Achromobacter spp was found in 10% of the 413 samples during the 8 months investigation period. The proportion of positive samples was stable among time but their location was unpredictable. The highest inoculum was finally found in the buckets used for biocleaning. DISCUSSION Samples from cleaning buckets taken by dry swabbing were at first negative, but the use of a non-routinely used sampling method allowed to discover the reservoir of this persistent contamination. CONCLUSION This investigation alerted us on the high microbiological risk associated with reusable plastic containers and the importance of a sampling method adapted to critical locations.

Abstract
Abstract
Study question
Can advanced machine learning applied to the preoperative assessment predict the testicular sperm extraction outcome in azoospermic context and how many patients are required?
Summary answer
Despite encouraging results (AUC = 92.0%, sensitivity = 83.9% and specificity = 84.2%), integrating new biomarkers would probably be more relevant than enrolling additional patients.
What is known already
Testicular sperm extraction (TESE) is an essential therapeutic tool for the male infertility management and is often the “last hope” before gamete donation for these patients. However, it is an invasive procedure and is successful in up to 50%. Until now, no model is sufficiently powerful to accurately predict the success of sperm retrieval in TESE. Among the few models already developed, the findings are highly disparate despite having common input data (preoperative assessment). Moreover, only few types of machine learning models and procedures have been investigated. Performances were mostly capped despite the inclusion sometimes of more than 1000 patients.
Study design, size, duration
Data of 175 patients who underwent TESE between 2012 and 2021 were retrospectively analyzed. The performances of a wide range of preprocessing methods and machine learning models (state-of-the-art methods in machine learning) we explored, evaluated, and compared. The objective was to predict the presence or absence of spermatozoa, using 17 parameters (clinical, hormonal, genetic, history) from the preoperative assessment. The study protocol was approved by a local ethics committee (IRB CER-2021-041).
Participants/materials, setting, methods
After data preprocessing (standardization…), Machine Learning models (Bayesian Naive Classification, logistic regression, k-nearest neighbor classifier, support vector machine, random forests, GradientBoosting and XGBoost) and Deep Learning models were tested. The validation procedure consisted of splitting the dataset into a training set and test set. Beyond the standard metrics (sensitivity, specificity, AUC-ROC), the identification of the most relevant variables and the learning curve to determine the optimal patient number to be included were performed.
Main results and the role of chance
At least one live spermatozoon was found in the testicular tissue of 104 (59.4%) patients (positive TESE) out of 175. The best performing model (Random Forest with appropriate preprocessing) obtained the following results on the test set: AUC = 92.0%, sensitivity = 83.9% and specificity = 84.2%, leading to an efficient tool, which gives additional and more relevant information than the different variables taken separately. Inhibin B, FSH and history of cryptorchidism were the variables with the most discriminating power. However, a plateau in the model performance was observed (beyond 110 patients), whatever the approach or the preprocessing used. A trend curve shows that beyond 110 patients, no improvement can be observed and cast doubt about the power of the traditional preoperative parameters assessed before TESE. The classic preoperative assessment can probably not fully predict the TESE outcomes. Further work is needed to be enhance with new hypothesis and the use of new biomarkers to be integrated into the models.
Limitations, reasons for caution
The main limitation was the monocentric design and the use of retrospective data.
Wider implications of the findings
Machine learning models can provide the basis for an enhanced decision support system tool in the context of azoospermia. Indefinitely increasing the number of participants is not likely to be the solution: further hypotheses and biomarkers integration into the models will probably be necessary to improve performance.

Abstract
Abstract
Study question
To evaluate the association between sleep parameters, sleep disorders and idiopathic infertility.
Summary answer
Some sleep parameters, such as bedtime, sleep latency and chronotypes, might be associated with male and female fertility.
What is known already
Some studies suggested that sleep might play an important role in reproductive health. Short sleep duration might interfere with the menstrual cycle, sperm parameters or natural fertility. The biological clock chronotype was found to be associated with fertility, with altered sperm parameters in the “evening” type and more reproductive troubles in the “intermediate” type when compared to the “morning” type. Irregular and night work schedules were also associated with some degree of fertility dysfunction, such as irregular menstrual cycles, a longer time to pregnancy, or male infertility. However, the interrelations between sleep and fertility are not fully elucidated.
Study design, size, duration
Fertile and infertile couples were recruited in the ALIFERT cross-sectional case–control multicentric study, between September 2009 and December 2013. The study group consisted of 94 infertile men and 95 infertile women, presenting with a primary idiopathic infertility of more than 12 months. The control group consisted in 85 fertile men and 86 fertile women who had a spontaneously conceived child under 2 years of age with a time to pregnancy less than 12 months.
Participants/materials, setting, methods
Male and female participants answered the French version of the Pittsburgh Sleep Quality Index, including questions about sleep timing and duration and symptoms of sleep disorders. Sleep parameters were compared between infertile and fertile participants for each sex, and between partners. The Wilcoxon-Mann-Whitney test was used to compare differences in sleep parameters due to a non-normal distribution, and the Fisher's exact test was used for qualitative variables.
Main results and the role of chance
Bedtime was significantly later for infertile compared to fertile male participants (p = 0.03). Infertile female participants had significantly later wake time, greater sleep latency and sleep apnea symptoms compared to fertile female participants (p ≤ 0.02). Fertile participants of both sexes were more frequently moderate morning types compared to infertile participants (p ≤ 0.04). No differences were observed regarding total sleep time, time spent in bed, sleep efficacy, insomnia, hypersomnia, or periodic leg movement symptoms. Infertile couples had more frequently different chronotypes than fertile couples (p = 0.02). Differences in wake time between partners were significantly greater among infertile couples (p < 0.01), but no differences were observed for bedtime, time spent in bed and total sleep time (p ≥ 0.22).
Limitations, reasons for caution
Sleep parameters were evaluated based on self-reported questionnaire. Further studies including objective measures of sleep will be needed to allow a more objective determination of sleep parameters. A discussion about mechanistic hypothesis should also be considered to better understand the links between sleep and fertility.
Wider implications of the findings
Sleep could be an original and innovative parameter to consider in the reproduction field. Further investigation is needed to elucidate how sleep and reproductive functions are interrelated and how sleep might constitute a useful modifiable target in infertility management.

Abstract
Abstract
Study question
To evaluate if the sperm small non-coding RNA (sncRNA) signature can be alterated in patients suffering from testicular cancer.
Summary answer
Sperm sncRNA profile is influenced by testicular cancer.
What is known already
Environmentally induced pathologies are associated with sperm sncRNA profile modifications which could have consequences on sperm quality but also on the offspring health. While this mechanism has been widely described in the case of metabolic and psycho-traumatic diseases, its relevance in testicular cancer needs to be assessed. Testicular cancer affects young men for which both genetic and environmental factors are known contributors.
Study design, size, duration
This pilot study aimed to compare sperm sncRNA profiles of 15 men suffering from testicular cancer with sperm sncRNA profile of 10 controle men. Semen samples were collected and stored in Tenon Hospital between 1999 and 2017 and donated to research (GERMETHEQUE biobank). Consent to use their samples was obtained from each patient (CPP 2.15.27) and the study protocol was approved by a local ethics committee (IRB CLEA-2021- 171).
Participants/materials, setting, methods
Sperm small RNA raw sequencing data was processed by the computational framework SPORTS1.0, which allows the annotation and quantification of small non-coding RNAs (tsRNAs, rsRNAs, ysRNA and miRNAs). DEseq 2 was used to identify sequences differentially expressed between patients and control samples. We also carried out a Gene Ontology analysis using miRNA targets according to the Metascape and DisGeNET Database.
Main results and the role of chance
In total, 77 deregulated sequences were found in sperm samples from testicular tumor patients compared to control men, including 17 that were down-regulated and 60 that were up-regulated. These sequences corresponded to 22 miRNAs, 25rsRNA, 11 tsRNA, 10 snRNA, 4 SnoRNA, 4 RNYs and 1 lncRNA sequences. Hierarchical Clustering of Differentially Expressed Genes using up and down regulation discriminates between control and testicular cancer samples. Gene Ontology analyses highlighted enriched processes including Neurodevelopmental Disorders, Adult and Childhood Medulloblastoma and Tumor initiation.
Limitations, reasons for caution
The current study was limited by the small patient number and the unavailability of the complete biological and oncogenic patient data.
Wider implications of the findings
Deciphering and validating the role of sperm sncRNAs may be a promising tool in testicular cancer diagnosis and may facilitate our understanding of the initiation and development of cancer in young adults.

Abstract
Rett syndrome may be treated by reactivating the silent copy of Mecp2 from the inactive X chromosome in female cells. Most studies that model Mecp2 reactivation have used mouse fibroblasts rather than neural cells, which would be critical for phenotypic reversal, and rely on fluorescent reporters that lack adequate sensitivity. Here, we present a mouse model based on a dual bioluminescent and fluorescent reporter to assess the level of reactivation of Mecp2 and the inactive X chromosome by treating neural stem cells with 5-azacytidine and Xist knockdown. We show that reactivation of Mecp2 and other X-linked genes correlates with CpG density, with distance from escapees, and, very strongly, with the presence of short interspersed nuclear elements. In addition, X-linked genes reactivated in neural stem cells overlap substantially with early reactivating genes by induced pluripotent stem cell reprogramming of fibroblasts or neuronal progenitors, indicating that X chromosome reactivation follows similar paths regardless of the technique or cell type used.

Abstract
Non-alcoholic fatty liver disease (NAFLD) is a highly prevalent chronic liver disease that occurs mostly in the context of insulin resistance and obesity. It has rapidly evolved into the most common cause of liver disease among children. The incidence is high in obese children and a greater risk of disease progression is associated with severe obesity, highlighting the role of nutrition. To date, there is no consensus on NAFLD management. This is a narrative review of clinical studies on the potential benefit of nutritional interventions, including lifestyle modifications, vitamins, docosahexaenoic acid, and probiotics in children with NAFLD. The Comité de nutrition de la Société Française de Pédiatrie (CN-SFP) emphasizes the effect of limiting added sugar intake, i.e., fructose or sucrose-containing beverages, and promoting physical activity in the care of NAFLD.

Abstract
STUDY QUESTION How do manufacturers perform embryotoxicity testing in their quality control programs when validating IVF consumables? SUMMARY ANSWER The Mouse Embryo Assay (MEA) and Human Sperm Survival Assay (HSSA) used for IVF disposables differed from one manufacturer to another. WHAT IS KNOWN ALREADY Many components used in IVF laboratories, such as culture media and disposable consumables, may negatively impact human embryonic development. STUDY DESIGN, SIZE, DURATION Through a questionnaire-based survey, the main manufacturers of IVF disposable devices were contacted during the period November to December 2018 to compare the methodology of the MEA and HSSA. We focused on catheters for embryo transfer, catheters for insemination, straws, serological pipettes, culture dishes and puncture needles used in the ART procedures. PARTICIPANTS/MATERIALS, SETTING, METHODS We approached the manufacturers of IVF disposables and asked for details about methodology of the MEA and HSSA performed for toxicity testing of their IVF disposable devices. All specific parameters like mouse strains, number of embryos used, culture conditions (media, temperature, atmosphere), extraction protocol, subcontracting, and thresholds were registered and compared between companies. MAIN RESULTS AND THE ROLE OF CHANCE Twenty-one companies were approached, of which only 11 answered the questionnaire. Significant differences existed in the methodologies and thresholds of the MEA and HSSA used for toxicity testing of IVF disposables. Importantly, some of these parameters could influence the sensitivity of the tests. LIMITATIONS, REASONS FOR CAUTION Although we approached the main IVF manufacturers, the response rate was relatively low. WIDER IMPLICATIONS OF THE FINDINGS Our study confirms the high degree of heterogeneity of the embryotoxicity tests performed by manufacturers when validating their IVF disposable devices. Currently, no regulations exist on this issue. Professionals should call for and request standardization and a future higher degree of transparency as regards embryotoxicity testing from supplying companies; moreover, companies should be urged to provide the users clear and precise information about the results of their tests and how testing was performed. Future recommendations are urgently awaited to improve the sensitivity and reproducibility of embryotoxicity assays over time. STUDY FUNDING/COMPETING INTEREST(S) This study did not receive any funding. L.D. declares a competing interest with Patrick Choay SAS. TRIAL REGISTRATION NUMBER N/A.

Abstract
OBJECTIVE To describe and compare the characteristics of women with placenta accreta spectrum (PAS) and their pregnancy outcomes according to the presence of placenta praevia and a prior caesarean section. DESIGN Prospective population-based study. SETTING All 176 maternity hospitals of eight French regions. POPULATION Two hundred and forty-nine women with PAS, from a source population of 520 114 deliveries. METHODS Women with PAS were classified into two risk-profile groups, with or without the high-risk combination of placenta praevia (or an anterior low-lying placenta) and at least one prior caesarean. These two groups were described and compared. MAIN OUTCOME MEASURES Population-based incidence of PAS, characteristics of women, pregnancies, deliveries and pregnancy outcomes. RESULTS The PAS population-based incidence was 4.8/10 000 (95% CI 4.2-5.4/10 000). After exclusion of women lost to follow up from the analysis, the group with placenta praevia and a prior caesarean included 115 (48%) women and the group without this combination included 127 (52%). In the group with both factors, PAS was more often suspected antenatally (77% versus 17%; P < 0.001) and more often percreta (38% versus 5%; P < 0.001). This group also had more hysterectomies (53% versus 21%, P < 0.001) and higher rates of blood product transfusions, maternal complications, preterm births and neonatal intensive care unit admissions. Sensitivity analysis showed similar results after exclusion of women who delivered vaginally. CONCLUSION More than half the cases of PAS occurred in women without the combination of placenta praevia and a prior caesarean delivery, and these women had better maternal and neonatal outcomes. We cannot completely rule out that some of the women who delivered vaginally had placental retention rather than PAS; however, we found similar results among women who delivered by caesarean. TWEETABLE ABSTRACT Half the women with PAS do not have both placenta praevia and a prior caesarean delivery, and they have better maternal outcomes.

Abstract
Historic wooden structures in Polar Regions are being adversely affected by decay fungi and a warming climate will likely accelerate degradation. Fort Conger and the Peary Huts at Lady Franklin Bay in northern Ellesmere Island are important international heritage sites associated with early exploration in the High Arctic. Fort Conger, built by Adolphus Greely and expedition members during the First International Polar Year in 1881, was dismantled and used by Robert Peary and his expedition crew in the early 1900's to build several smaller shelters. These historic structures remain at the site but are deteriorating. This investigation examines the fungi associated with wood decay in the historic woods. Soft rot was observed in all 125 wood samples obtained from the site. The major taxa found associated with the decayed wood were Coniochaeta (18%), Phoma (13%) Cadophora (12%), Graphium (9%), and Penicillium (9%) as well as many other Ascomycota that are known to cause soft rot in wood. Micromorphological observations using scanning electron microscopy of historic wooden timbers that were in ground contact revealed advanced stages of type I soft rot. No wood destroying Basidiomycota were found. Identification of the fungi associated with decay in these historic woods is a first step to better understand the unusual decomposition processes underway in this extreme environment and will aid future research to help control decay and preserve this important cultural heritage.

Abstract
The evolution of medical care for transgender people currently makes it possible to propose fertility preservation. Fertility preservation should be initiated before the start of hormonal treatments and/or surgical procedures. The "reproductive" aspect and the desire for parenthood among transgender people have long been ignored. However, these aspects are important to consider and fertility preservation should be discussed before the start of the physical transition. The aim of this review is to assess the literature on fertility preservation for transgender women ("male to female"). Many uncertainties remain regarding the impact of hormonal treatments on the reproductive functions of transgender women and their reversibility. However, the significant increase in the number of recently published articles is evidence of the improvement in the conditions of access to these procedures for women starting a transition process. Nevertheless, there are still a number of barriers that can prevent or delay this process.

Abstract
Atherosclerosis is one of the most common vascular pathologies in the world. Among the most commonly performed endovascular treatments, percutaneous transluminal angioplasty (PTA) has been showing significantly positive clinical outcomes. Due to the complex geometries, material properties and interactions that characterize PTA procedures, finite element analyses of acute angioplasty balloon deployment are limited. In this work, finite element method (FEM) was used to simulate the inflation and deflation of a semi-compliant balloon within the 3D model of a stenosed artery with two different plaque types (lipid and calcified). Self-defined constitutive models for the balloon and the plaque were developed based on experimental and literature data respectively. Balloon deployment was simulated at three different inflation pressures (10, 12 and 14 atm) within the two plaque types. Balloon sizing influence on the arterial elastic recoil obtained immediately after PTA was then investigated. The simulated results show that calcified plaques may lead to higher elastic recoil ratios compared to lipid stenosis, when the same balloon inflation pressures are applied. Also, elastic recoil increases for higher balloon inflation pressure independent of the plaque type. These findings open the way for a data-driven assessment of angioplasty balloon sizing selection and clinical procedures optimization.Clinical Relevance- The FE model developed in this work aims at providing quantitative evaluation of recoil after balloon angioplasty. It may be useful for both manufacturers and clinicians to improve efficiency of angioplasty balloon device design and sizing selection with respect to plaque geometry and constitution, consequently enhancing clinical outcomes.

Abstract
INTRODUCTION Common major pathogens like Pseudomonas aeruginosa are identified in the airways of patients with cystic fibrosis (CF) and non-CF bronchiectasis. However, other opportunistic bacterial pathogens like Achromobacter xylosoxidans complex, Stenotrophomonas maltophilia and non-tuberculous mycobacteria are currently emerging in CF and are also reported in non-CF bronchiectasis. BACKGROUND The emergence of opportunistic bacterial pathogens has been recognized in CF through annual national reports of sputum microbiology data. Despite common factors driving the emergence of bacteria identified in CF and non-CF bronchiectasis patients, bronchiectasis registries have been created more recently and no longitudinal analysis of recorded microbiological data is currently available in the literature, thereby preventing the recognition of emerging bacteria in patients with non-CF bronchiectasis. OUTLOOK A longitudinal follow-up of microbiological data is still needed in non-CF bronchiectasis to identify emerging opportunistic bacterial pathogens. Homogeneity in practice of sputum microbiological examination is also required to allow comparative analysis of data in CF and non-CF bronchiectasis. CONCLUSION Bacterial pathogens recognized as emerging in CF have to be more carefully monitored in non-CF bronchiectasis in view of their association with deterioration of the lung disease.

Abstract
Marine food-reliant subsistence systems such as those in the African Middle Stone Age (MSA) were not thought to exist in Europe until the much later Mesolithic. Whether this apparent lag reflects taphonomic biases or behavioral distinctions between archaic and modern humans remains much debated. Figueira Brava cave, in the Arrábida range (Portugal), provides an exceptionally well preserved record of Neandertal coastal resource exploitation on a comparable scale to the MSA and dated to ~86 to 106 thousand years ago. The breadth of the subsistence base-pine nuts, marine invertebrates, fish, marine birds and mammals, tortoises, waterfowl, and hoofed game-exceeds that of regional early Holocene sites. Fisher-hunter-gatherer economies are not the preserve of anatomically modern people; by the Last Interglacial, they were in place across the Old World in the appropriate settings.

Abstract
NR4A2, a member of the nuclear receptor superfamily, is involved in modulation of target gene transcription, regulating several developmental processes such as regulation of cellular homeostasis, neuronal development, inflammation and carcinogenesis. 2q24.1 deletions are extremely rare, and only 1 patient with a de novo deletion encompassing only NR4A2 gene was reported so far. We report 3 additional patients with a de novo deletion encompassing NR4A2: 2 patients have deletions encompassing only NR4A2 gene and 1 patient has a deletion including NR4A2 and the first exon of GPD2. Our patients presented a neurodevelopmental disorder including language impairment, developmental delay, intellectual disability and/or autism spectrum disorder. We suggest that NR4A2 haploinsufficiency is implicated in neurodevelopmental disorder with high penetrance.

Abstract
Xanthomas are rare bone tumors that occur more often in patients with hyperlipidemia or metabolic disorders. We report the case of a 9-year-old child presenting with right shoulder pain after a trauma. A benign osteolytic lesion was found in the proximal humeral metaphysis. Curettage of the lesion was performed. Histologic findings confirmed intraosseous xanthoma. Although there was no evidence of dyslipidemia or metabolic disease, the patient suffered local recurrence at the 8-month follow-up, requiring a second surgery with bone grafting. This difficult and rare diagnosis must be kept in mind with osteolytic lesions.

Abstract
OBJECTIVES Polycystic ovarian syndrome (PCOS) brings complications in the management of the assisted reproductive technology (ART) because of an oocyte quality probably impaired due to modifications of intra- and extra-ovarian factors. Our study aimed to investigate the extended culture in PCOS patients and its influence on the cumulative live birth rates. METHODS Fifty-nine PCOS patients (as defined by the Rotterdam criteria) and 114 normo-ovulatory patients (i.e. with tubal, male or idiopathic infertility, regular cycles and AMH>2ng/mL) aged<37years old who underwent a 1st or 2nd ART attempt with extended culture to day 6 were included from October 2015 to December 2017. The blastulation and cumulative live birth rates were compared between the two groups. RESULTS The PCOS and control patients were 32.22 and 32.91years old respectively (P=0.05). The median number of oocytes retrieved was significantly higher in the PCOS group and the median oocyte maturity rate significantly lower compared with controls. The blastulation rates were similar between the PCOS and the control groups, respectively 57.8% vs. 58.6%, P=0.88. Because of the risks of hyperstimulation syndrome, a freeze all strategy was achieved for 38.9% of PCOS patients vs. 14.0% of the control patients (P<0.01). The cumulative live birth rates were not statistically different: 31.7% in the PCOS group vs. 37.2% in the control group, P=0.50. CONCLUSIONS PCOS was not observed to affect the extended culture nor the cumulative live birth rates in comparison to normo-ovulatory patients, supporting the blastocyst transfer strategy as a suitable option to PCOS patients.

Abstract
OBJECTIVES This French multicenter, cross-sectional, observational study aimed to describe the family history of atopy in infants with cow's milk protein allergy (CMPA), and the related diagnostic approaches used by specialists in a real-life ambulatory setting. PATIENTS AND METHODS In total, 1674 infants with suspected CMPA [median age 4.5 months (range: 0.1-18.0), males 54%] were enrolled in the study by 466 private physicians (pediatricians: 97%). Family history of atopy was defined as a known history of atopy in at least one first- (father, mother, and/or sibling) and/or second-degree relative (grandparents, uncles, and aunts), as reported by parents to physicians. RESULTS Atopy in a first-degree relative was more common among infants with documented or high probability of CMPA (in 84% and 80% of cases, respectively, vs. the other subgroups, P=0.005). Most infants experienced digestive (92%) and skin (61%) symptoms suggestive of CMPA. Delayed reactions were reported in 64% of infants. According to a post-classification based on the results of previous diagnostic tests and procedures, 1133 infants (68%) had highly probable (52%) or documented CMPA (16%). In these infants, a history of atopy was reported in first- and/or second-degree relative(s) in 86% of cases (81% in first-degree relatives). Whatever the family history of atopy, the characteristics of the infants were similar, except for fewer pets in the case of negative family atopy (14% vs. 25%, P<0.001). Atopy in a parent was more frequent in infants who presented with the first signs suggestive of CMPA within the first 6 months of life vs. those with later first symptoms (75% vs. 65%, P=0.063). CONCLUSION This French study confirms the high rate of family history of atopy in first-degree relatives of infants with probable or documented CMPA.

Abstract
Background Epicutaneous immunotherapy (EPIT) is a promising method for treating food allergies. In animal models, EPIT induces sustained unresponsiveness and prevents further sensitization mediated by Tregs. Here, we elucidate the mechanisms underlying the therapeutic effect of EPIT, by characterizing the kinetics of DNA methylation changes in sorted cells from spleen and blood and by evaluating its persistence and bystander effect compared to oral immunotherapy (OIT). Methods BALB/c mice orally sensitized to peanut proteins (PPE) were treated by EPIT using a PPE‐patch or by PPE‐OIT. Another set of peanut‐sensitized mice treated by EPIT or OIT were sacrificed following a protocol of sensitization to OVA. DNA methylation was analyzed during immunotherapy and 8 weeks after the end of treatment in sorted cells from spleen and blood by pyrosequencing. Humoral and cellular responses were measured during and after immunotherapy. Results Analyses showed a significant hypermethylation of the Gata3 promoter detectable only in Th2 cells for EPIT from the 4th week and a significant hypomethylation of the Foxp3 promoter in CD62L+ Tregs, which was sustained only for EPIT. In addition, mice treated with EPIT were protected from subsequent sensitization and maintained the epigenetic signature characteristic for EPIT. Conclusions Our study demonstrates that EPIT leads to a unique and stable epigenetic signature in specific T‐cell compartments with downregulation of Th2 key regulators and upregulation of Treg transcription factors, likely explaining the sustainability of protection and the observed bystander effect.

Abstract
DNA replication occurs in a defined temporal order known as the replication-timing (RT) program. RT is regulated during development in discrete chromosomal units, coordinated with transcriptional activity and 3D genome organization. Here, we derived distinct cell types from F1 hybrid musculus × castaneus mouse crosses and exploited the high single-nucleotide polymorphism (SNP) density to characterize allelic differences in RT (Repli-seq), genome organization (Hi-C and promoter-capture Hi-C), gene expression (total nuclear RNA-seq), and chromatin accessibility (ATAC-seq). We also present HARP, a new computational tool for sorting SNPs in phased genomes to efficiently measure allele-specific genome-wide data. Analysis of six different hybrid mESC clones with different genomes (C57BL/6, 129/sv, and CAST/Ei), parental configurations, and gender revealed significant RT asynchrony between alleles across ∼12% of the autosomal genome linked to subspecies genomes but not to parental origin, growth conditions, or gender. RT asynchrony in mESCs strongly correlated with changes in Hi-C compartments between alleles but not as strongly with SNP density, gene expression, imprinting, or chromatin accessibility. We then tracked mESC RT asynchronous regions during development by analyzing differentiated cell types, including extraembryonic endoderm stem (XEN) cells, four male and female primary mouse embryonic fibroblasts (MEFs), and neural precursor cells (NPCs) differentiated in vitro from mESCs with opposite parental configurations. We found that RT asynchrony and allelic discordance in Hi-C compartments seen in mESCs were largely lost in all differentiated cell types, accompanied by novel sites of allelic asynchrony at a considerably smaller proportion of the genome, suggesting that genome organization of homologs converges to similar folding patterns during cell fate commitment.

Abstract
OBJECTIVE Prospective assessment of the management of urinary tract infections (UTI) in the nursing homes of the Hauts-de-France region. PATIENTS AND METHODS A 50-question form had to be filled in for up to five consecutive residents treated for UTI in each nursing home. If necessary, diagnoses were reclassified according to the 2014 French Infectious Diseases Society guidelines. Analyses were presented per supposed (reported) and reclassified diagnoses. RESULTS Of 397 contacted facilities, 134 participated and informed 444 UTI episodes. Reported diagnostic criteria were burning urination (32%), malodorous urine (29%), confusion (28%), and turbid urine (19%). Twenty-one percent of diagnoses were based on erroneous criteria. Less than 50% of residents had a urine dipstick test performed and 94% a urine culture. The main pathogen was Escherichia coli. Reported indications were uncomplicated cystitis (32%), unspecified UTI (26%), complicated cystitis (9%), while no reason was given in 25% of cases. Only 10% of diagnoses were consistent with the guidelines: complicated cystitis (49%), asymptomatic bacteriuria (21%), acute pyelonephritis (21%), male UTI (9%). Almost 85% of prescriptions were active on the isolated bacteria. The empirical antibiotic therapy was consistent with the diagnosis in 16% of cases (30% for reclassified diagnoses). The two most prescribed antibiotic classes were fluoroquinolones (22.1%) and oral third-generation cephalosporins (19.1%). Only two of 157 possible de-escalations were performed. Duration of treatment was adequate for 19% of UTIs (9.6% of reclassified cases). CONCLUSION Our study revealed multiple deficiencies in diagnosis, antibiotic choice, treatment duration, and reevaluation.

Abstract
Due to transient gut immaturity, most very preterm infants receive parenteral nutrition (PN) in the first few weeks of life. Yet providing enough protein and energy to sustain optimal growth in such infants remains a challenge. Extrauterine growth restriction is frequently observed in very preterm infants at the time of discharge from hospital, and has been found to be associated with later impaired neurodevelopment. A few recent randomized trials suggest that intensified PN can improve early growth; whether or not such early PN improves long-term neurological outcome is still unclear. Several other questions regarding what is optimal PN for very preterm infants remain unanswered. Amino acid mixtures designed for infants contain large amounts of branched-chain amino acids and taurine, but there is no consensus on the need for some nonessential amino acids such as glutamine, arginine, and cysteine. Whether excess growth in the first few weeks of life, at a time when very preterm infants receive PN, has an imprinting effect, increasing the risk of metabolic or vascular disease at adulthood continues to be debated. Even though uncertainty remains regarding the long-term effect of early PN, it appears reasonable to propose intensified initial PN. The aim of the current position paper is to review the evidence supporting such a strategy with regards to the early phase of nutrition, which is mainly covered by parenteral nutrition. More randomized trials are, however, needed to further support this type of approach and to demonstrate that this strategy improves short- and long-term outcome.

Abstract
Recently, surgical site infections due to non-tuberculous mycobacteria (NTM) have been linked to heater-cooler unit contamination. The European Centre for Disease Prevention and Control and manufacturers now recommend the use of hydrogen peroxide in filtered water to fill heater-cooler unit tanks. After implementation of these measures in our hospital, heater-cooler units became heavily contaminated by opportunistic waterborne pathogens such as Pseudomonas aeruginosa and Stenotrophomonas maltophilia. No NTM were detected but fast-growing resistant bacteria could impair their detection. The efficiency of hydrogen peroxide and chlorhexidine-alcohol was compared in situ. Chlorhexidine-alcohol treatment stopped waterborne pathogen contamination and NTM were not cultured whereas their detection efficiency was probably improved.
