Abstract
AIM The aim of these recommendations is to set forth an individualized approach to the management of early postmenopausal women (i.e., within the first 10 years after natural menopause) covering all aspects of lifestyle and therapeutic management, with or without menopause hormone therapy (MHT). MATERIALS AND METHODS Literature review and consensus of French expert opinion. Recommendations were graded according to the HAS methodology and levels of evidence derived from the international literature, except when there was no good-quality evidence. SUMMARY RECOMMENDATIONS The beginning of menopause is an ideal time for each woman to evaluate her health status by assessing her bone, cardiovascular, and cancer-related risk factors that may be amplified by postmenopausal estrogen deficiency and by reviewing her lifestyle habits. Improving lifestyle, including nutrition and physical activity, and avoiding risk factors (notably smoking), should be recommended to all women. MHT remains the most effective treatment for vasomotor symptoms but it could be also recommended as first-line treatment for the prevention of osteoporosis in early postmenopausal women at low to moderate risk for fracture. The risks of MHT differ depending on its type, dose, duration of use, route of administration, timing of initiation, and whether a progestogen is used. There is reasonable evidence that using transdermal estradiol in association with micronized progesterone or dydrogesterone may limit both the venous thromboembolic risk associated with oral estrogens and the risk of breast cancer associated with synthetic progestins. Treatment should be individualized to each woman, by using the best available evidence to maximize benefits and minimize risks, with periodic reevaluation of its benefit-risk balance. For bothersome genitourinary syndrome of menopause (GSM) symptoms, vaginal treatment with lubricants and moisturizers is recommended as first-line treatment together with low-dose vaginal estrogen therapy, depending on the clinical course. No recommendation of an optimal duration of MHT can be made, but it must take into consideration the initial indication for MHT as well as each woman's benefit-risk balance. Management of gynecological side-effects of MHT is also examined. These recommendations are endorsed by the Groupe d'Etude sur la Ménopause et le Vieillissement hormonal (GEMVI) and the Collège National des Gynécologues-Obstétriciens Français (CNGOF).

Abstract
INTRODUCTION For some patients, local hormonal or non-hormonal treatments for genitourinary syndrome of menopause (SGUM) are contraindicated or insufficiently effective. Different physical therapies such as vaginal laser therapy, radiofrequency therapy, photobiomodulation therapy and local injection of hyaluronic acid, autologous fat (lipofilling) and platelet rich plasma (PRP) have been proposed as alternatives. OBJECTIVE The objective of this review was to elaborate guidelines for clinical practice regarding the physical therapies proposed for management of vulvovaginal atrophy (AVV). METHODS A systematic review of the literature on AVV management with physical therapies was conducted on Medline between January 2014 and December 2020. RESULTS Regarding vaginal laser therapy, there are few randomized controlled trials and no formal conclusions can be drawn. The fractional CO2 laser did not demonstrate its superiority over local estrogen therapy. The ERBIUM:YAG laser has not been studied in randomized controlled trials. The lack of follow-up on the vaginal laser and the series of cases reporting risks of vaginal stenosis or chronic pain do not encourage recommending it as a first-line treatment. The literature concerning other physical treatments of AVV is weak concerning the genital area. CONCLUSION CO2 or ERBIUM:YAG vaginal lasers are not the first-line treatment for AVV (grade C). In patients with a contraindication to local hormonal treatments, treatment with vaginal CO2 laser or ERBIUM:YAG may be considered after information about the risks (burn, stenosis, pain) (expert opinion). The other physical treatments of SGUM have to be evaluated.

Abstract
OBJECTIVE It is already known that children born after slow frozen embryo replacement have a significantly higher birth weight compared to children born after fresh embryo transfer. Similar data have been reported related to frozen embryo transfer using an open vitrification system. However, few data relative to birth weight using a complete embryo closed vitrification system has been reported. The purpose of this study was to know if frozen embryo in closed vitrification system is associated with a higher birth weight compared to fresh embryo replacement. DESIGN This was a monocentric retrospective cohort study, 371 children were issued from fresh embryo replacement and 127 from vitrified embryo transfer. MATERIALS AND METHODS All singletons born after fresh or vitrified embryo transfer between January 2011 and April 2015 were included. Births from the vitrified or fresh transfers of egg or sperm donation, and preimplantation genetic diagnosis were excluded. In addition, pregnancies with more than one gestational sac at the first ultrasound were excluded. An analysis of covariance (ANCOVA) was used for multivariate analysis. RESULTS Mean birth weight was 205g higher in the frozen embryo compared with fresh embryos transfer groups (3368g vs. 3163g respectively, P<0.001). This difference remained after multivariate analysis adjusted on confounding factors such as gestational age, maternal age, maternal body mass index (BMI), tobacco exposure, number of embryo transferred and birth order (P<0.001).. CONCLUSIONS Embryo frozen in closed vitrification system is associated with a higher birth weight compared to fresh embryo replacement. Our findings are consistent with the previous studies related to slow freezing and open vitrification systems data. The effects of controlled ovarian stimulation (COS), ex vivo culture conditions and cryopreservation systems on birth weight of children born should be further explored.

Abstract
BACKGROUND Complete and partial androgen insensitivity syndrome (CAIS, PAIS) are associated with an increased risk of gonadal germ cell cancer (GGCC). Recent guidelines recommend gonadectomy in women with CAIS in late adolescence. Nevertheless, many adult women prefer to retain their gonads. AIMS This study aims to explore attitudes towards gonadectomy in AIS in centres around the world, estimate the proportion of adults with retained gonads and/or who developed GGCC, and explore reasons for declining gonadectomy. METHODS A survey was performed among health care professionals who use the International DSD Registry (I-DSD). RESULTS Data were provided from 22 centres in 16 countries on 166 women (CAIS) and 26 men (PAIS). In CAIS, gonadectomy was recommended in early adulthood in 67% of centres; 19/166 (11.4%) women refused gonadectomy. Among 142 women who had gonadectomy, evidence of germ cell neoplasm in situ (GCNIS), the precursor of GGCC, was reported in 2 (1.4%) out of 8 from whom pathology results were formally provided. Nine out of 26 men with PAIS (34.6%) had retained gonads; 11% of centres recommended routine gonadectomy in PAIS. CONCLUSION Although development of GGCC seems rare, gonadectomy after puberty is broadly recommended in CAIS; in PAIS this is more variable. Overall, our data reflect the need for evidence-based guidelines regarding prophylactic gonadectomy in AIS.

Abstract
Anal canal duplication (ACD) is the least frequent digestive duplication. Symptoms are often absent but tend to increase with age. Recognition is, however, important as almost half of the patients with ACD have concomitant malformations. We present the clinical history of an eleven-year-old girl with ACD followed by a review of symptoms, diagnosis, treatment, and prognosis based on all the reported cases in English literature.

Abstract
This study focused on the detection of rare earth oxides, used as tracers for the identification of polymer materials, using XRF (X-ray fluorescence) spectrometry. The tests were carried out in a test system device which allows the collection of static measurements of the samples' spectrum through the use of energy dispersive X-ray fluorescence technology. A sorting process based on tracers added into the polymer matrix is proposed in order to increase sorting selectivity of polypropylene during end-of-life recycling. Tracers consist of systems formed by one or by several substances dispersed into a material, to add a selective property to it, with the aim of improving the efficiency of sorting and high speed identification. Several samples containing rare earth oxides (Y(2)O(3), CeO(2), Nd(2)O(3), Gd(2)O(3), Dy(2)O(3), Er(2)O(3) and Yb(2)O(3)) in different concentrations were prepared in order to analyse some of the parameters which can influence the detection, such as the concentration of tracers, the acquisition time and the possible overlapping among the tracers. This work shows that by using the XRF test system device, it was possible to detect 5 of the 7 tracers tested for 1min exposure time and at a concentration level of 1000ppm. These two parameters will play an important role in the development of an industrial device, which indicates the necessity of further works that needs to be conducted in order to reduce them.

Abstract
The aim of the present study was to investigate the spatio-temporal characteristics of the neural correlates of declarative memory formation as assessed by the subsequent memory effect, i.e. the difference in encoding activity between subsequently remembered and subsequently forgotten items. Different operations could account for these effects. In particular, it has been proposed that successful memory formation depends on the organization of the information at the time of encoding, an operation accomplished by the working memory system. Consequently, functional magnetic resonance imaging studies have already shown that the very same regions that are involved in certain working memory processes are also involved in declarative memory formation. Here, we used magnetoencephalography to investigate whether the subsequent memory effects in these regions are present throughout picture stimulus presentation, postulating ongoing working memory operations as an effective factor. The results showed that subsequent memory effects began to appear after about 300 ms post stimulus onset over bilateral temporal areas and left parietal regions and were sustained throughout the recording epoch (1000 ms). Roughly parallel to these effects, we identified a left frontal subsequent memory effect, which, however, was less sustained than the other effects. In addition, we revealed a late subsequent memory effect over the right occipital region, which has not been described previously in the event-related potential literature. These sustained subsequent memory effects are suggestive of working memory processes that may enable deep semantic and perceptual processing. Additionally, contextually constrained visual perception after top-down modulation may account for a more efficient encoding of the complex scene.

Abstract
Four methods for the simulation of the Wiener process with constant drift and variance are described. These four methods are (1) approximating the diffusion process by a random walk with very small time steps; (2) drawing directly from the joint density of responses and reaction time by means of a (possibly) repeated application of a rejection algorithm; (3) using a discrete approximation to the stochastic differential equation describing the diffusion process; and (4) a probability integral transform method approximating the inverse of the cumulative distribution function of the diffusion process. The four methods for simulating response probabilities and response times are compared on two criteria: simulation speed and accuracy of the simulation. It is concluded that the rejection-based and probability integral transform method perform best on both criteria, and that the stochastic differential approximation is worst. An important drawback of the rejection method is that it is applicable only to the Wiener process, whereas the probability integral transform method is more general.

Abstract
Phonological consistency describes to what extent a letter string in one word is pronounced equally in other words. Phonological reliability describes to what extent a sublexical unit is usually consistent throughout a language. The relationship between the two concepts was investigated by comparing five sublexical units (onset-consonants, vowel, end-consonants, and the concatenation of the vowel with begin- or end-consonants) in Dutch and English with respect to their reliability and to how their consistency was related to naming errors and latencies. In a regression analysis, naming latencies and errors on genuine Dutch words (consistent) and imported words (inconsistent) were predicted by the phonological consistency of the five units. The same was done for two sets of English naming data. Consistency had a much stronger effect in Dutch than in English naming studies when all five units were considered. The special role of the vowel plus end-consonants, which has been found in English naming data, could not be demonstrated in Dutch. In both languages, the size of consistency effects mirrors the reliability of the five units.

Abstract
In two experiments, the perceptual similarity between a strong tonal melody and various transpositions was investigated using a paradigm in which listeners compared the perceptual similarity of a melody and its transposition with that of the same melody and another transposition. The paradigm has the advantage that it provides a direct judgment regarding the similarity of transposed melodies. The experimental results indicate that the perceptual similarity of a strong tonal melody and its transposition is mainly determined by two factors: (1) the distance on the height dimension between the original melody and its transposition (pitch distance), and (2) the distance between keys as inferred from the circle of fifths (key distance). The major part of the variance is explained by the factor pitch distance, whereas key distance explains only a small part.
