Abstract
OBJECTIVE To study the fertility outcomes of women who tried to conceive after breast cancer treatment and fertility preservation. DESIGN Retrospective observational, bicentric cohort study. SUBJECTS AND EXPOSURE All patients who had undergone fertility preservation before breast cancer treatment between January 2013, and July 2019 were included (n=844). The end-point date was March 1, 2022. Patients with missing data on pregnancy attempts after cancer diagnosis (n=195) were excluded from the pregnancy analysis. MAIN OUTCOME MEASURES Cumulative incidences of pregnancy and live birth were calculated. For women who became pregnant, the time to conception was calculated between the first fertility preservation consultation and the estimated day of conception. For those who did not conceive, we considered the time between first fertility preservation consultation and the end-point date or the date of patient death. A Cox regression model was used to study the predictive factors of pregnancy and live birth. RESULTS Among the 649 patients with available data on pregnancy attempts after breast cancer diagnosis, 255 (39.3% [35.5-43.2]) tried to conceive (median follow-up 6.5 years). Overall, 135 (52.9% [46.6-59.2]) of these patients achieved a pregnancy, mainly through unassisted conception (79.3% [72.8-84.8]), and 99 reported a live birth (representing 38.8% of patients who attempted conception). In our cohort, 48 months after the first fertility preservation consultation, the cumulative incidence of pregnancy was 33.1% ([27.6-37.9]). After adjustment for age, parity, type of chemotherapy administration and endocrine therapy, only multiparity at diagnosis and absence of chemotherapy were positive predictive factors of pregnancy after cancer. Of the 793 patients who had vitrified oocytes/embryos, 68 used them (27% [21.3-32.5] of the patients who tried to conceive), resulting in 8 live births (11.8% [5.2-21.9]). Women who used their cryopreserved oocytes/embryos were older at the first consultation of fertility preservation (HR 1.71(1.42-2.21)), and chose more often to vitrify embryos (HR 1.76(1.28-2.23). CONCLUSION Although pregnancy rates after fertility preservation for breast cancer are low, most conceptions are achieved without medical assistance. Our findings provide useful information to advise women on the different techniques of fertility preservation, their efficacy and safety, as well as the relatively high chances of unassisted conception.

Abstract
BACKGROUND The COVID-19 pandemic was characterized by an abundance of information, some of it reliable and some of it misinformation. Evidence-based data on the impact of misinformation on attitudes and behaviours remains limited. Studies indicate that older adults are more likely to embrace and disseminate misinformation than other population groups, making them vulnerable to misinformation. The purpose of this article is to explore the effects of misinformation and information overload on older adults, and to present the management strategies put in place to deal with such effects, in the context of COVID-19. METHODS A qualitative exploratory approach was adopted to conduct this research. A total of 36 semi-structured interviews were conducted with older adults living in Quebec, Canada. The interviews were fully transcribed and subjected to a thematic content analysis. RESULTS Participants said they could easily spot misinformation online. Despite this, misinformation and its treatment by the media could generate fear, stress and anxiety. Moreover, the polarization induced by misinformation resulted in tensions and even friendship breakdowns. Participants also denounced the information overload produced largely by the media. To this end, the participants set up information routines targeting the sources of information and the times at which they consulted the information. CONCLUSIONS This article questions the concept of vulnerability to misinformation by highlighting older adults' agency in managing misinformation and information overload. Furthermore, this study invites us to rethink communication strategies by distinguishing between information overload and misinformation.

Abstract
PURPOSE The objective of the present study was to evaluate whether oocyte vitrification following controlled ovarian stimulation (COS) for fertility preservation (FP) delays the initiation of neoadjuvant chemotherapy (NAC) for breast cancer (BC) as compared to in vitro maturation (IVM). METHODS We performed a retrospective cohort study including all BC patients eligible for oocyte vitrification following COS or in vitro maturation (IVM) before initiation of NAC between January 2016 and December 2020. The inclusion criteria were female patients aged between 18 and 40, with confirmed non metastatic BC, with indication of NAC, who have had oocyte retrieval for FP after COS, or IVM + / - cryopreservation of ovarian tissue (OTC). Various time points related to cancer diagnosis, FP, or chemotherapy were obtained from a medical record review. RESULTS A total of 197 patients with confirmed BC who had oocyte retrieval following COS (n = 57) or IVM + / - OTC (n = 140) for FP prior to NAC were included. Overall, the average time from cancer diagnosis to chemotherapy start was similar between patients having undergone COS or IVM before oocyte vitrification (37.3 ± 13.8 vs. 36. 8 ± 13.5 days; p = 0.89). CONCLUSIONS The indication of NAC for BC should not be considered as an impediment to urgent COS for oocyte vitrification for FP.

Abstract
OBJECTIVE To study whether fertility preservation strategies using ovarian stimulation or without using it impact long-term disease-free survival of patients with breast cancer. DESIGN Retrospective bicentric cohort study. SETTING Two university hospitals. PATIENT(S) In this study, 740 women with breast cancer, aged 18-43 years, who received primary fertility preservation between 2013 and 2019 after a diagnosis of localized breast cancer were included. INTERVENTION(S) Overall, 328 patients underwent at least 1 ovarian stimulation cycle (STIM group) and 412 had a technique without hormonal administration (no STIM group). MAIN OUTCOME MEASURE(S) Disease-free survival and overall survival up to May 2021 were compared between the 2 groups by log-rank test. Cox proportional-hazard regression model was used for multivariable analyses. RESULT(S) Out of the 740 women who underwent fertility preservation, follow-up data were available for 269 women in the STIM group (82%) and 330 (80%) in the no STIM group. Kaplan-Meier estimates of disease-free survival at 4 years were 87.9% (82.8%-92.2%) and 83.1% (78.4%-87.3%) in the STIM and no STIM groups, respectively. After adjustment on prognostic parameters, no significant difference in breast cancer recurrence rate was observed between the STIM and no STIM groups (hazard ratios, 0.83 [0.64-1.08]). Kaplan-Meier estimate of overall survival at 4 years was 97.6% (95.3%-99.2%) and 93.6% (90.9%-95.9%) in the STIM and no STIM groups, respectively. Overall survival was higher in the STIM group than no STIM group (log-rank test). After adjustment on prognostic parameters, the risk of death remained significantly lower in the STIM group (Hazard Ratio, 0.55 [0.35-0.85]). CONCLUSION(S) In our cohort, STIM for fertility preservation in breast cancer did not significantly impact disease-free survival but was associated with higher overall survival. The disease-free survival and overall survival of young patients with breast cancer were not impacted by fertility preservation techniques irrespective of the timing of chemotherapy (neoadjuvant or adjuvant) and the use of ovarian stimulation. Nevertheless, because death and recurrence were rare events, these results should be taken with caution.

Abstract
STUDY QUESTION Can ovarian tissue cryopreservation (OTC) be performed after controlled ovarian hyperstimulation (COH)? SUMMARY ANSWER Unilateral oophorectomy after transvaginal oocyte retrieval is feasible on stimulated ovaries during one surgical step. WHAT IS KNOWN ALREADY In the fertility preservation (FP) field, the timeframe between patient referral and start of curative treatment is limited. Combining oocyte pick-up with ovarian tissue (OT) extraction has been reported to improve FP but COH applied before OT extraction is not currently recommended. STUDY DESIGN, SIZE, DURATION This retrospective cohort-controlled study involved 58 patients who underwent oocyte cryopreservation immediately followed by OTC between September 2009 and November 2021. The exclusion criteria were a delay between oocyte retrieval and OTC of >24 h (n = 5) and IVM of oocytes obtained ex vivo in the ovarian cortex (n = 2). This FP strategy was performed either after COH (stimulated group, n = 18) or after IVM (unstimulated group, n = 33). PARTICIPANTS/MATERIALS, SETTING, METHODS Oocyte retrieval followed by OT extraction on the same day was performed either without previous stimulation or after COH. Adverse effects of surgery and ovarian stimulation, mature oocyte yield and pathology findings of fresh OT were retrospectively analysed. Thawed OTs were analysed prospectively, for vascularization and apoptosis using immunohistochemistry, when patient consent was obtained. MAIN RESULTS AND THE ROLE OF CHANCE No surgical complication occurred after OTC surgery in either group. In particular, no severe bleeding was associated with COH. The number of mature oocytes obtained increased after COH (median = 8.5 (25% = 5.3-75% = 12.0)) compared to the unstimulated group (2.0 (1.0-5.3), P < 0.001). Neither ovarian follicle density nor cell integrity was affected by COH. Fresh OT analysis showed congestion in half of the stimulated OT which was higher than in the unstimulated OT (3.1%, P < 0.001). COH also increased haemorrhagic suffusion (COH + OTC: 66.7%; IVM + OTC: 18.8%, P = 0.002) and oedema (COH + OTC: 55.6%; IVM + OTC: 9.4%, P < 0.001). After thawing, the pathological findings were similar between both groups. No statistical difference in the number of blood vessels was observed between the groups. The oocyte apoptotic rate in thawed OT was not statistically different between the groups (ratio of positive cleaved caspase-3 staining oocytes/total number of oocytes equal to median 0.50 (0.33-0.85) and 0.45 (0.23-0.58) in unstimulated and stimulated groups respectively, P = 0.720). LIMITATIONS, REASONS FOR CAUTION The study reports FP from a small number of women following OTC. Follicle density and other pathology findings are an estimate only. WIDER IMPLICATIONS OF THE FINDINGS Unilateral oophorectomy can be successfully performed after COH with limited bleeding risk and an absence of impact on thawed OT. This approach could be proposed to post pubertal patients when the number of mature oocytes expected is low or when the risk of residual pathology is high. The reduction of surgical steps for cancer patients also has positive implications for introducing this approach into clinical practice. STUDY FUNDING/COMPETING INTEREST(S) This work was made possible through the support of the reproductive department of Antoine-Béclère Hospital and of the pathological department of Bicêtre Hospital (Assistance Publique Hôpitaux de Paris, France). The authors have no conflict of interest to disclose in this study. TRIAL REGISTRATION NUMBER N/A.

Abstract
BRCA 1/2 pathogenic variants increase the risk of developing early and aggressive breast cancers (BC). For these patients, fertility potential can be directly affected by oncologic treatments. In addition, evidence indicates that BRCA-mutated women had a significant reduction in their ovarian reserve. In order to improve their chances of conception after the completion of cancer treatments, fertility preservation should be proposed before the administration of gonadotoxic drugs, ideally by oocyte vitrification after controlled ovarian hyperstimulation (COH). The present investigation aims to assess the ovarian response to COH in BRCA 1/2-pathogenic-variant carriers diagnosed with BC. Patient characteristics and COH outcomes were compared between BRCA-positive (n = 54) and BRCA-negative (n = 254) patients. The number of oocytes recovered did not differ between the two groups. However, the oocyte maturation rate and the number of mature oocytes obtained (7 (4.5-11.5) vs. 9 (5-14) oocytes, p = 0.05) were significantly lower in the BRCA-mutated patients. Although individualized COH protocols should be discussed, BRCA-mutated patients would benefit from FP before BC occurs, in order to cope with the potential accelerated decline of their ovarian reserve, optimize the success rate of FP by repeating COH cycles, and to preserve the feasibility of PGT-M by collecting a large amount of eggs.

Abstract
We describe the preliminary on-sky results of the KIDs Interferometer Spectrum Survey (KISS), a spectral imager with a 1 deg field of view (FoV). The instrument operates in the range 120–180 GHz from the 2.25m Q-U-I JOint TEnerife telescope in Teide Observatory (Tenerife, Canary Islands), at 2 395m altitude above sea level. Spectra at low resolution, up to 1.45 GHz, are obtained using a fast (3.72 Hz mechanical frequency) Fourier transform spectrometer, coupled to a continuous dilution cryostat with a stabilized temperature of 170mK that hosts two 316-pixel arrays of lumped-element kinetic inductance detectors. KISS generates more than 3 000 spectra per second during observations and represents a pathfinder to demonstrate the potential for spectral mapping with large FoV.We give an overall description of the spectral mapping paradigm and we present recent results from observations, in this paper.

Abstract
CONCERTO (CarbON CII line in post-rEionisation and ReionisaTiOn) is a large field-of-view (FoV) spectro-imager that has been installed on the Cassegrain Cabin of Atacama Pathfinder EXperiment (APEX) telescope in April 2021. CONCERTO hosts 2 focal planes and a total number of 4000 Kinetic Inductance Detectors (KID), with an instantaneous FoV of 18.6 arcminutes in the range of 130-310 GHz. The spectral resolution can be easily tuned down to 1 GHz depending on the scientific target. The scientific program of CONCERTO has many objectives, with two main programs focused on mapping the fluctuations of the [CII] line intensity in the reionisation and postreionisation epoch (4.5<z<8.5), and on studying galaxy clusters via the thermal and kinetic Sunyaev-Zel’dovich (SZ) effect. CONCERTO will also measure the dust and molecular gas contents of local and intermediate-redshift galaxies, it will study the Galactic star-forming clouds and finally it will observe the CO intensity fluctuations arising from 0.3<z<2 galaxies.
The design of the instrument, installation at APEX and current status of the commissioning phase and science verification will be presented. Also we describe the deployment and first on-sky tests performed between April and June 2021.

Abstract
Abstract
Study question
Does oocyte vitrification for fertility preservation (FP) delay the initiation of neoadjuvant chemotherapy for breast cancer?
Summary answer
The indication of neoadjuvant chemotherapy for breast cancer should not be considered as an impediment to urgent oocyte vitrification for FP.
What is known already
FP is considered as one of the most important issues to address for young breast cancer patients. Cryopreservation of oocytes or embryos may be considered after controlled ovarian hyperstimulation (COH) or in vitro maturation (IVM). Pregnancies have been reported after reutilization of oocytes frozen following both procedures. Although oocyte competence is better after COH, this strategy requires on average 13 days to be achieved. In addition, the safety of ovarian stimulation before tumor removal is currently not formally established. In case of neoadjuvant chemotherapy, the risk-benefit balance of COH is not well known.
Study design, size, duration
Retrospective cohort study including all breast cancer patients eligible for oocyte vitrification following COH or IVM before initiation of neoadjuvant chemotherapy between January 2016 and December 2020.
Participants/materials, setting, methods
Inclusion criteria were: female patients with confirmed non metastatic breast cancer, 18 to 40 years of age, with indication of neoadjuvant chemotherapy, who have had oocyte retrieval for FP after COH or IVM +/- cryopreservation of ovarian tissue. Various time-points related to cancer diagnosis, FP or chemotherapy were obtained from medical record review.
Main results and the role of chance
A total of 198 patients with confirmed breast cancer who had oocyte retrieval following COH (n = 57) or IVM +/- cryopreservation of ovarian tissue (n = 141) for FP prior to neoadjuvant chemotherapy were included. Although women in IVM group were significantly younger as compared to patients who underwent COH (31.7 ± 4.2 vs. 33.3 ± 4.0 years, p = 0.019), ovarian reserve parameters, BMI and cancer stage did not differ between the two groups. Overall, the average time from cancer diagnosis to chemotherapy start was similar between patients having undergone COH or IVM before oocyte vitrification (37.3 ± 13.8 vs. 36.9 ±13.5 days in COH and IVM groups respectively, p=0.857).
Limitations, reasons for caution
The time from referral to FP consultation may have influenced the type of FP. In addition, the retrospective nature of the present analysis may constitute a limitation. Moreover, the efficiency and security of the different FP strategies used has not been analysed.
Wider implications of the findings
Oocyte vitrification following COH or IVM was not associated with delayed breast cancer treatment in the neoadjuvant setting, so long as there was a prompt FP referral. Young patients undergoing neoadjuvant chemotherapy should be informed of these findings to avoid unnecessary anxiety due to concern for delays.

Abstract
PURPOSE The aim of this study was to evaluate the outcomes of frozen oocytes or embryos cryopreserved after controlled ovarian stimulation (COS) or in vitro maturation (IVM) for female cancer patients who underwent a fertility preservation (FP) prior to gonadotoxic therapy. METHODS A retrospective cohort study from 2009 to December 2017 was conducted. Among the 667 female cancer patients who underwent oocytes or embryos cryopreservation for FP, 40 (6%) have returned to the fertility clinic between 2011 and 2019 to use their frozen material after being cured. We compared these thaw cycles outcomes according to the techniques used at the time of cryopreservation. RESULTS Among the 40 women cancer survivors who used their cryopreserved material, thirty patients have benefited from at least one embryo transfer. Ten patients did not have an embryo transfer since the oocytes did not survive after the thawing process or because no embryo was obtained after fertilization. We related three live births following FP using IVM (two from frozen oocytes and one after embryo cryopreservation). Five live births were obtained when COS was performed at the time of FP (one from frozen oocytes and four after embryo cryopreservation). CONCLUSIONS Our preliminary results, although they are obtained in a small sample, are encouraging and show that different FP techniques can be used in female cancer patients and lead to live births. IVM is one of the options available that does not delay the start of chemotherapy or if ovarian stimulation using gonadotropins is contraindicated.

Abstract
Rising from the province of Wuhan in China, the new coronavirus SARS-CoV-2 broke out in winter 2019, causing a global pandemic. In most cases reported, COVID-19 symptoms include cough, dyspnea, myalgia and asthenia. In some cases, the disease can also cause severe respiratory distress syndrome, requiring intensive care. Recent studies suggest that SARS-CoV-2 infection predisposes to thromboembolic event such as pulmonary embolism. Moreover, there is an overlap between signs and symptoms of pulmonary embolism and COVID-19, which brings a challenge for the diagnosis and could potentially be fatal. Nevertheless, the incidence rate of pulmonary embolism in cases of COVID-19 is currently not known. In this paper we describe six cases of pulmonary embolism associated with COVID-19.

Abstract
Objective The aims of this study were to follow up the monitoring, health and anxiety from women who became pregnant after an embryo transfer or a intrauterine insemination during the COVID-19 epidemic in France Study Design This is a single centre, retrospective study from December 2019 to March 2020 based on a phone call interview using a specific questionnaire sheet specially developed for this study. Questionnaires from 104 pregnant women were completed and descriptive data are then analyzed. Results Women with ongoing pregnancies (n = 88) did not change their physician visits. The COVID-19 outbreak has created no or few additional stresses for 77 % of pregnant women since the lockdown started. We report a miscarriage rate of 14.4 % (n = 15) and documented 10 patients (11.3 %) who had symptoms related to COVID-19. No severe symptoms and no hospitalization in intensive care unit were identified. Conclusion The epidemic context did not disrupt the medical monitoring of pregnancies and we did not recover an increased rate of miscarriage after ART. None of the patients who had COVID-related symptoms presented with severe clinical manifestations. Surprisingly, pregnant women were psychologically able to experience the lockdown.

Abstract
In vitro maturation (IVM) of oocytes retrieved at germinal vesicle stage, followed by vitrification of mature oocytes, has emerged as a fertility preservation (FP) option. This technique was first developed for patients with polycystic ovarian syndrome. In this population, providing LH activity prior to oocyte collection has been associated with better IVM outcomes. However, the benefit of this treatment in normo-ovulatory breast cancer (BC) patients undergoing IVM for FP purpose has never been investigated. To assess if the absence of therapeutic intervention prior to oocyte retrieval for IVM modifies IVM outcomes in BC patients undergoing urgent FP, we performed a non-inferiority, randomized controlled trial. The main outcome was the total number of mature oocytes obtained and cryopreserved after IVM. A total of 172 normo-ovulatory women, suffering from BC, 18 to 39 years of age received no injection or a subcutaneous injection of hCG or GnRH agonist (GnRHa) 36 h before oocytes retrieval according to randomized allocation. The total number of cryopreserved oocytes were 5.1 ± 3.8, 5.4 ± 3.8, and 6.0 ± 4.2 oocytes, respectively in the without, hCG and GnRHa groups. Mean differences were not significant between the three groups (- 0.5; CI 97.5% [- 2.03:1.02] and - 0.22; CI 97.5% [- 1.75:1.32], respectively). Intention to treat analyses failed to show non-inferiority in the "without injection group" in comparison with hCG or GnRHa groups. Our results are not conclusive enough to modify our practices and to stop administering hCG or GnRHa before IVM cycles for FP. The study was retrospectively registered to clinical trial (ID NCT03954197) in May 2019.

Abstract
INTRODUCTION Chemotherapy may cause infertility in young survivors of breast cancer. Various fertility preservation techniques increase the likelihood of survivors becoming genetic mothers. Disclosure of cancer diagnosis may impact decision making about fertility preservation. This protocol will develop and test the effectiveness of a web-based decision aid for helping women with breast cancer to make well-informed choices about fertility preservation. METHODS AND ANALYSIS This study will be conducted in three phases using mixed methods. In phase I, the aim is to develop a web-based patient decision aid (PDA) in French with a steering committee and using a focus group of five women already treated for breast cancer. In phase II, the face validity of the decision aid will be assessed using questionnaires. In phase III, the PDA will be assessed by a two-arm randomised controlled trial. This will involve a quantitative evaluation of the PDA in clinical practice comparing the quality of the decision-making process between usual care and the PDA. The primary outcome will be informed choice and its components. The secondary outcomes will be decisional conflict and anxiety. Data will be collected during and after an oncofertility consultation. Phase III is underway. Since September 2018, 52 participants have been enrolled in the study and have completed the survey. We expect to have results by February 2020 for a total of 186 patients. ETHICS AND DISSEMINATION This study protocol was approved by the Ouest V Research Ethics Board. Results will be spread through peer-reviewed publications, and reported at suitable meetings. TRIAL REGISTRATION NUMBER The ClinicalTrials.gov registry .(NCT03591848).

Abstract
Clusters of galaxies are used to map the large-scale structures in the universe and as probe of universe evolution. They can be observed through the Sunyaev-Zel’dovich (SZ) effect. In this respect the spectro-imaging at low resolution frequency is an important tool, today, for the study of cluster of galaxies. We have developed KISS (KIDs Interferometer Spectrum Survey), a spectrometric imager dedicated to the secondary anisotropies of the Cosmic Microwave Background (CMB). The multi-frequency approach permits to improve the component separation with respect to predecessor experiments. In this paper, firstly, we provide a description of the scientific context and the state of the art of SZ observations. Secondly, we describe the KISS instrument. Finally, we show preliminary results of the ongoing commissioning campaign.

Abstract
STUDY QUESTION What threshold values of ultrasonographic antral follicle count (AFC) and serum anti-Müllerian hormone (AMH) levels should be considered for ensuring the cryopreservation of sufficient number of in vitro matured (IVM) oocytes, in cancer patients seeking fertility preservation (FP)? SUMMARY ANSWER AFC and serum AMH values >20 follicles and 3.7 ng/ml, respectively, are required for obtaining at least 10 IVM oocytes for cryopreservation. WHAT IS KNOWN ALREADY IVM of cumulus oocyte complexes (COCs) followed by oocyte cryopreservation has emerged recently as an option for urgent FP. Recent data have reported that, in healthy patients, 8-20 cryopreserved oocytes after ovarian stimulation would maximize the chance of obtaining a live birth. Although both AFC and AMH have been reported as predictive factors of IVM success in infertile patients with polycystic ovary syndrome (PCOS), there is a dramatic lack of data regarding the values of these parameters in oncological patients as candidates for FP. STUDY DESIGN, SIZE, DURATION From January 2009 to April 2015, we prospectively studied 340 cancer patients, aged 18-41 years, as candidates for oocyte cryopreservation following IVM. PARTICIPANTS/MATERIALS, SETTING, METHODS All patients had AFC and AMH measurements, 48-72 h before oocyte retrieval, regardless of the phase of the cycle. COCs were recovered under ultrasound guidance 36 h after hCG priming. Logistic regression allowed the determination of threshold values of AFC and AMH, for obtaining at least 8, 10 or 15 matures oocytes frozen after the IVM procedure. Similar analyses were performed for a final number of mature oocytes ≤2. MAIN RESULTS AND THE ROLE OF CHANCE Among the 340 cancer patients included, 300 were diagnosed with breast cancers, 14 had hematological malignancies and 26 underwent the procedure for others indications. Overall, the mean age of the population was 31.8 ± 4.5 years. Mean AFC and serum AMH levels were 21.7 ± 13.3 follicles and 4.4 ± 3.8 ng/ml, respectively. IVM was performed in equal proportions during the follicular or luteal phase of the cycle (49 and 51%, respectively). Statistical analysis showed that AFC and AMH values above 28 follicles and 3.9 ng/ml, 20 follicles and 3.7 ng/ml and 19 follicles and 3.5 ng/ml are required, respectively, for obtaining at least 15, 10 or 8 frozen IVM oocytes with a sensitivity ranging from 0.82 to 0.90. On the contrary, ≤2 IVM oocytes were cryopreserved when AFC and AMH were <19 follicles and 3.0 ng/ml, respectively. LIMITATIONS, REASONS FOR CAUTION Although the potential of cryopreserved IVM oocytes from cancer patients remains unknown, data obtained from infertile PCOS women have shown a dramatically reduced competence of these oocytes when compared with that of oocytes recovered after ovarian stimulation. As a consequence, the optimal number of IVM oocytes frozen in candidates for FP is currently unpredictable. WIDER IMPLICATIONS OF THE FINDINGS Cryopreservation of oocytes after IVM should be considered in the FP strategy when ovarian stimulation is unfeasible, in particular when markers of the follicular ovarian status are at a relatively high range. Further investigation is needed to objectively assess the real potential of these IVM oocytes after cryopreservation. Therefore, even when a good COCs yield is expected, we should systematically encourage IVM in combination with ovarian tissue cryopreservation.

Abstract
Advances on cryopreservation techniques now allow considering oocyte, embryo or ovarian tissue freezing for female fertility preservation. Originally developed for patients suffering from cancer, fertility preservation has rapidly invaded others medical fields, and represents now the standard of care for all young patient diagnosed with a disease that could impair fertility or having to receive possibly gonadotoxic treatment. As a result, autoimmune diseases, some genetic pathologies or iterative pelvic surgeries, at risk of premature ovarian failure, have become common indications of fertility preservation. In addition, the social egg freezing aiming at preventing the age-related fertility decline is still debated in France, although authorized in numerous countries. This review will discuss the different strategies of fertility preservation in young girls and women of reproductive age, regarding different medical or non-medical indications.

Abstract
OBJECTIVES Oocyte vitrification using an open device is thought to be a source of microbiological and chemical contaminations that can be avoided using a closed device. The principal purpose of this study was to compare the two vitrification protocols: closed and open system. The secondary aim was to study the effects of the storage in the vapor phase of nitrogen (VPN) on oocytes vitrified using an open system and to compare it to those of a storage in liquid nitrogen (LN). METHODS Forty-four patients have been included in our study between November 2014 and May 2015. Two hundred and fourteen oocytes have been vitrified at germinal vesicle (GV), metaphase I (0PB) and metaphase II (1PB) stages. We vitrified 96 oocytes (59 GV/37 0PB) using a closed vitrification device and 118 oocytes (57 GV/31 0PB/30 1PB) using an open device. The vitrified oocytes were then stored either in LN or in VPN. The main outcome measures were the survival rate after warming (SR), meiosis resumption rate (MRR) and maturation rate (MR). RESULTS The global post-thaw SR was significantly higher for oocytes vitrified using an open system (93.2%) compared to those vitrified using a closed one (64.5%; P<0.001). On the contrary, there was no significant difference in terms of global MRR and MR (82.1% vs. 87.5% and 60.7% vs. 61.2% using closed and open system respectively). The SR, MRR and the MR were not significantly different when vitrified oocytes were stored in VPN or LN (91.6, 83.8, 64.5% vs. 93.9, 89.8, 59.1% respectively). CONCLUSION Taking into account the limits of our protocol, the open vitrification system remains the more efficient system. The use of sterile liquid nitrogen for oocyte vitrification and the subsequent storage in vapor phase of nitrogen could minimize the hypothetical risks of biological and chemical contaminations.

Abstract
Behçet's disease is a relapsing, immune-mediated systemic vasculitis that may affect blood vessels of all types and sizes. Nowadays, the etiology remains unclear. In the absence of a biological marker or pathognomonic radiology, the diagnosis is mainly based on clinical manifestations. The cardiovascular involvement, known as "angio-Behçet", is relatively common and affects up to 40% of patients. It typi- cally occurs in a young male, usually during the onset of the disease. In general, immunosuppressive and anticoagulant therapies initiated early are likely to induce a remarkable cli- nical improvement. Nevertheless, prompt recognition of the polymorphous cardiovascular manifestations of the disease is challenging and may be responsible for some considerable delay prior to initiation of adequate therapy. The aim of this article is to describe the spectrum of cardiovascular involve- ments of Behçet's disease in order to optimize detection and therapeutic management.

Abstract
Fertility preservation strategies have been developed for men and women whose fertility is compromised for medical reasons, especially in case of cancer therapy. At present, many reliable options for preserving fertility are available. However, a part of these fertility preservation methods, despite being promising, are still considered experimental. Nevertheless, there are still situations where no methods can be offered. Remarkable scientific progress is currently underway to improve available techniques and to develop new technologies to solve problems with current fertility strategies. These new options may drastically change reproductive options for young patients facing germ cell loss and hence sterility. Therefore, oncofertility counseling by a specialist is recommended for all young cancer patients having to undergo treatment that may reduce fertility potential.

Abstract
BACKGROUND New forms and varieties of craniosynostoses are continuously identified due to the current increased interest of clinicians and genetists especially since the introduction of microarray-based comparative genomic hybridization (Array-CGH) techniques in the diagnostic setting of patients with craniofacial anomalies. METHODS In this report, we describe the case of an infant who associated the early fusion of the metopic and both the coronal sutures. The interaction of the early fusion of the anterior group of the main cranial sutures gave the infant a particular clinical phenotypes with a Y configuration of the frontal bone and a globally reduced size of the skull. Such a deformity was observed in utero and was subsequently confirmed by the postnatal imaging of the head. RESULTS This phenotype was never described previously in antenatal period to our knowledge. The array-CGH showed a heterozygous 9.0 Mb deletion in the chromosomal region 7p21.1p21.3 encompassing approximately 25 other genes, spanning from THSD7A to TWIST1/FERD3L. CONCLUSION This case further illustrates the variability of the clinical spectrum of craniofacial disorders associated with TWIST1 abnormalities. It is important to note that the Saethre-Chotzen syndrome caused by microdeletion is generally characterized by a mental disability. However, of interest, the postoperative psychomotor development of the child considered hereby was within the normal limits.

Abstract
Amiodarone is an antiarrhythmic agent among the I most powerful and the most frequently used for the control of recurrent ventricular tachycardia and the secondary prevention of recurrent atrial fibrillation. Its use is not without risk. Although highly effective, it may induce various, sometimes severe, side effects, particularly at the thyroid level.In patients receiving amiodarone, one can encounter biological changes without clinical repercussion. Some may present a true thyroid disease, either hyper- or hypothyroidism. In this literature review, we will see how to prevent, diagnose, and treat these complications,if required.

Abstract
We report the case of a patient presenting with L-thyroxine pseudomalabsorbtion, a figure in which patients are in a state of biological, and, frequently, clinical hypothyroidism secondary to a lack of adherence to substitutive thyroid treatment. We then review the different causes of true thyroid hormones malabsorption and the different approaches to these situations. We also suggest diagnostic and therapeutic attitudes for clinicians facing suspicious cases of hormone malabsorption.

Abstract
BACKGROUND There is a general consensus in the literature that schizophrenia causes difficulties with facial emotion perception and discrimination. Functional brain imaging studies have observed reduced limbic activity during facial emotion perception but few studies have examined the relation to flat affect severity. METHOD A total of 26 people with schizophrenia and 26 healthy controls took part in this event-related functional magnetic resonance imaging study. Sad, happy and neutral faces were presented in a pseudo-random order and participants indicated the gender of the face presented. Manual segmentation of the amygdala was performed on a structural T1 image. RESULTS Both the schizophrenia group and the healthy control group rated the emotional valence of facial expressions similarly. Both groups exhibited increased brain activity during the perception of emotional faces relative to neutral ones in multiple brain regions, including multiple prefrontal regions bilaterally, the right amygdala, right cingulate cortex and cuneus. Group comparisons, however, revealed increased activity in the healthy group in the anterior cingulate, right parahippocampal gyrus and multiple visual areas. In schizophrenia, the severity of flat affect correlated significantly with neural activity in several brain areas including the amygdala and parahippocampal region bilaterally. CONCLUSIONS These results suggest that many of the brain regions involved in emotional face perception, including the amygdala, are equally recruited in both schizophrenia and controls, but flat affect can also moderate activity in some other brain regions, notably in the left amygdala and parahippocampal gyrus bilaterally. There were no significant group differences in the volume of the amygdala.

Abstract
The use of a multiplexing readout for an array of bolometers simplifies the electronics and wiring, so making the readout of large arrays of bolometers (>100) feasible. Here we describe a time domain multiplexing technique and its performance based on the use of quantum-point-contact high-electron-mobility-transistors as low temperature (to approximately 100 mK) switches for measuring high impedance (5...70 MOmega) resistances and sensors. The presented system is well matched to ground based millimetric astronomy demands.

Abstract
Little is known about the identities and roles of antigen-presenting cells upon exposure to antigens of respiratory syncytial virus (RSV). Here, we focused on elucidating the importance of alveolar macrophages in conferring protective immunity in mice administered a liposome-encapsulated recombinant fragment of the RSV G protein. Mice were depleted of alveolar macrophages by intranasal inoculation of liposome-encapsulated dichloromethylenediphosphonic acid (DMDP). Mice depleted of alveolar macrophages prior to immunization developed reduced levels of serum RSV-neutralizing antibody and showed dramatically impaired protection against RSV challenge. The severity of interstitial inflammation was also markedly reduced in macrophage-depleted mice. In conclusion, this study demonstrates a pivotal role for alveolar macrophages during exposure to liposome-encapsulated RSV antigen in initiating both protective and histopathological responses against RSV.

Abstract
The role of hepatitis B virus HBx protein in the carcinogenesis associated with chronic viral infection remains ill-defined. Indeed, pleiotropic effects have been ascribed to HBx: in addition to its well-documented ability to indirectly stimulate transcription, the protein has been reported to affect cell growth, signal transduction, DNA repair and apoptosis. In this work, we generated Chang (CCL-13)-derived cell lines constitutively expressing wild type or mutant HBx, as a model of HBx-host cell interaction closer to the chronic infection setting, than the classically used transient expression systems. We document the potentiation by HBx of the apoptotic cell death pathway in the recipient cells. This effect is unlikely to rely on p53 activity since the protein is functionally inactivated in CCL-13. In addition, antioxidants and cyclosporin A failed to reduce the apoptotic response back to the normal level, suggesting that production of reactive oxygen species and calcineurin activation are not directly involved in the proapoptotic effect of HBx. In contrast, our data show that transactivation and stimulation of apoptosis are tightly linked HBx activities. Finally, expression of transactivation-active protein did not result in detectable change in the pattern of MAP kinases phosphorylation nor did it affect the ability of the host cell to repair in vitro irradiated plasmid DNA.

Abstract
This article introduces a less usual type of marital therapy. It describes the advantages and the difficulties of a team of male-female cotherapists in jointly conducting a marital therapy. Could this psy-chotherapeutic process allow the couple to better settle relational impasses and learn more rapidly to face the challenges inherent to life as a couple? Drawing from their personal experiences as cotherapists, the authors discuss this issue. They constantly underline the specificity and the implications of this type of therapeutic approach in the precise framework of a systematic-interactional model.
