STUDY QUESTION Is pronuclear transfer (PNT) capable of restoring embryo developmental arrest caused by cytoplasmic inferiority of in vitro -grown (IVG) mouse oocytes? SUMMARY ANSWER PNT to in vivo matured cytoplasm significantly improved embryo development of IVG mouse oocytes, leading to living, fertile offspring. WHAT IS KNOWN ALREADY In vitro follicle culture has been considered as a fertility preservation option for cancer patients. Studies describing the culture of human follicles remain scarce, owing to low availability of tissue. Mouse models have extensively been used to study and optimize follicle culture. Although important achievements have been accomplished, including the production of healthy offspring in mice, IVG oocytes are of inferior quality when compared to in vivo -grown oocytes, likely because of cytoplasmic incompetence. STUDY DESIGN, SIZE, DURATION The study was carried out from September 2020 to February 2022. In total, 120 15-day-old B6D2 mice were used to perform secondary follicle culture and assess the quality of IVG oocytes. In vivo -grown control oocytes were obtained from 85 8- to 12-week-old B6D2 mice, following ovarian stimulation. For sperm collection, four B6D2 males between 10 and 14 weeks old were used. For embryo transfer, 14 8- to 12-week-old CD1 females served as surrogate mothers and 10 CD1 vasectomized males 10–24 weeks old were used to generate pseudo-pregnant females. Finally, for mating, four B6D2 female mice aged 8–10 weeks and two B6D2 male mice aged 10 weeks old were used to confirm the fertility of nuclear transfer (NT)-derived pups. PARTICIPANTS/MATERIALS, SETTING, METHODS Secondary follicles from 15-day-old B6D2 mice were isolated from the ovaries and cultured for 9 days, before a maturation stimulus was given. Following 16–18 h of maturation, oocytes were collected and evaluated on maturation rate, oocyte diameter, activation rate, spindle morphology, calcium-releasing ability, and mitochondrial membrane potential. For every experiment, in vivo -grown oocytes were used as a control for comparison. When cytoplasmic immaturity and poor embryo development were confirmed in IVG oocytes, PNT was performed. For this, the pronuclei from IVG oocytes, created following parthenogenetic activation and IVF, were transferred to the cytoplasm of fertilized, in vivo -grown oocytes. Genetic analysis and embryo transfer of the generated embryos were implemented to confirm the safety of the technique. MAIN RESULTS AND THE ROLE OF CHANCE Following 9 days of follicle culture, 703 oocytes were collected, of which 76% showed maturation to the metaphase II stage. Oocyte diameters were significantly lower in IVG oocytes, measuring 67.4 μm versus 73.1 μm in controls (P < 0.001). Spindle morphology did not differ significantly between IVG and control oocytes, but calcium-releasing ability was compromised in the IVG group. An average calcium release of 1.62 arbitrary units was observed in IVG oocytes, significantly lower than 5.74 in control oocytes (P < 0.001). Finally, mitochondrial membrane potential was inferior in IVG compared to the control group, reaching an average value of 0.95 versus 2.27 (P < 0.001). Developmental potential of IVG oocytes was assessed following parthenogenetic activation with strontium chloride (SrCl
2 ). Only 59.4% of IVG oocytes cleaved to two cells and 36.3% reached the blastocyst stage, significantly lower than 89.5% and 88.2% in control oocytes, respectively (P < 0.001 and 0.001). Both PNT and spindle transfer (ST) were explored in pilot experiments with parthenogenetically activated oocytes, as a means to overcome poor embryo development. After the added value of NT was confirmed, we continued with the generation of biparental embryos by PNT. For this purpose, IVG and control oocytes first underwent IVF. Only 15.5% of IVG oocytes were normally fertilized, in contrast to 45.5% in controls (P < 0.001), with resulting failure of blastocyst formation in the IVG group (0 versus 86.2%, P < 0.001). When the pronuclei of IVG zygotes were transferred to the cytoplasm of control zygotes, the blastocyst rate was restored to 86.9%, a similar level as the control. Genetic analysis of PNT embryos revealed a normal chromosomal profile, to a rate of 80%. Finally, the generation of living, fertile offspring from PNT was possible following embryo transfer to surrogate mothers. LARGE-SCALE DATA N/A. LIMITATIONS, REASONS FOR CAUTION Genetic profiles of analysed embryos from PNT originate from groups that are too small to draw concrete conclusions, whilst ST, which would be the preferred NT approach, could not be used for the generation of biparental embryos owing to technical limitations. Even though promising, the use of PNT should be considered as experimental. Furthermore, results were acquired in a mouse model, so validation of the technique in human IVG oocytes needs to be performed to evaluate the clinical relevance of the technology. The genetic profiles from IVG oocytes, which would be the ultimate characterization for chromosomal abnormalities, were not analysed owing to limitations in the reliable analysis of single cells. WIDER IMPLICATIONS OF THE FINDINGS PNT has the ability to overcome the poor cytoplasmic quality of IVG mouse oocytes. Considering the low maturation efficiency of human IVG oocytes and potential detrimental effects following long-term in vitro culture, NT could be applied to rescue embryo development and could lead to an increased availability of good quality embryos for transfer.

The Amazon has a wide diversity, including forest species with timber and non-timber potential, which often have their use restricted due to a lack of silvicultural information. Thus, the present study aimed to evaluate the effect of substrates and temperatures on seed germination of Aspidosperma vagarsii. Therefore, the premise of a completely randomized design was followed, in a 3 x 3 factorial scheme, with three substrates (paper, sand and vermiculite) and three temperatures (20, 25 and 30 °C). The germination percentage, germination speed index and mean germination time were determined, as well as germination relative frequency graphs. In addition, the weight of a thousand seeds, the number of seeds per kilo, and the moisture content was determined. The weight of thousand seeds was equal to 276.4 g, with 3,618 seeds per kilo, and a moisture content of 9.5%. There was no interaction between the studied factors. The sand substrate and temperatures of 20 and 25 °C presented the best results for seed germination of A. vargasii. [ABSTRACT FROM AUTHOR]

Recent developments in generating gametes via in vitro gametogenesis (IVG) from induced pluripotent stem cells (iPSCs) and their successful use for reproductive purposes in animals strongly suggest that soon these methods could also be used in human reproduction. At least two questions emerge in this context: (a) if a legislator should permit their use and (b) if ethical claims emerge that support their provision, e.g., by public health care systems. This urges an ethical reflection of the new reproductive options this technique might offer. Since the concept of reproductive freedom is a key aspect for the ethical evaluation of artificial reproductive technologies (ARTs), it is necessary to analyze if the new possibilities emerging from IVG fall within the scope of this concept. The results may constitute a morally relevant difference between different imaginable applications of IVG and potentially justify differences in claims to access this technology.

Résumé: En France, malgré les moyens contraceptifs disponibles, le taux des interruptions volontaires de grossesse (IVG) des femmes mineures est stable depuis plusieurs années. L'absence de dialogue sur la sexualité, les interdits familiaux et un défaut de perception du risque de grossesse contribuent à l'absence de contraception. Rapidement, une fois la grossesse constatée et la décision prise, avec ou sans consentement du partenaire, les participantes s'appuient sur les centres de planification et d'éducation à la sexualité pour réaliser l'IVG. Le choix et la présence du majeur accompagnant posent problème. Certains professionnels incitent à une hospitalisation lors de l'IVG médicamenteuse pour sécuriser la procédure. Des ruptures du secret ont été rapportées. Après l'IVG, la contraception médicalisée n'est pas toujours utilisée. In France, despite the contraceptive means available, the rate of voluntary abortion (VA) of underage women has been stable for several years. The lack of dialogue about sexuality, family prohibitions and a lack of perception of the risk of pregnancy contribute to the absence of contraception. Quickly, once the pregnancy has been established and the decision made, with or without the partner's consent, the women rely on the planning and sexuality education centers to do the VA. The choice and presence of the accompanying adult is problematic. Some professionals encourage hospitalization during the medical abortion in order to make the procedure safe. Breaches of secrecy have been reported. After the abortion, medical contraception is not always used. [ABSTRACT FROM AUTHOR]

In vitro oral bioaccessibility of Cadmium (Cd) in two low (XGSJ), (SHQI) and two high (CGBC), (SIYM) Cd-accumulating affinity cultivars of Brassica rapa ssp. chinensis L. (pak choi) grown on Cd-contaminated Alfisol soil was assessed. In this study, physiologically based extraction test (PBET) and in vitro gastrointestinal (IVG) were chosen to assess the bioaccessibility for Cd by stimulating human digestion of plant material. The pak choi cultivars were grown on Cd-contaminated soil with six different Cd concentrations (0, 0.5, 1.0, 1.5, 2.0, 2.5, and 3.0 mg kg−1). The phytoavailability of Cd in soils was also measured through Mehlich-3 extraction and sequential extraction method. Plants were harvested and analyzed for their total Cd content and afterward extracted using PBET and IVG to provide the estimate of oral bioaccessibility for the human health risks of metal contamination in pak choi.

The present study was to evaluate the Cedar seed germination and the handling of different substrates to elucidate what is the best condition for the species. The experiment was conducted in the laboratory, without control of incidence of light or temperature, leaving them as much as possible under natural conditions. Treatments consisted of four treatments and four repetitions, each repetition consisted of 10 subrepetitions, totaling 40 units (plastic cups) per treatment. Seeds were sown with two seeds per cup. The characteristics evaluated were the percentage of germination and germination speed index (GSI). It is concluded this way that the seeds subjected to the earth and sand worked to conduct tests for germination cedar seeds were those that gave higher percentages of germination and IVG. While the substrates, commercial and land forest were considered unfavorable for conducting germination tests for cedar seeds.

14. In Vitro Gametogenesis: A Research Timeline and Implications for the Future of Assisted Reproductive Technology

Buckley, Nicole and Buckley, Nicole
- Abstract
The novel reproductive technology, In Vitro Gametogenesis (IVG), includes the process of obtaining mature viable germ cells from pluripotent stem cells. To do so, embryonic stem cells and induced pluripotent stem cells are specified to primordial germ cells and differentiated to form gametes that undergo further maturation, which subsequently may undergo in vitro fertilization to form an embryo. With this capability, IVG holds the power to provide a novel treatment option for human infertility. As of now, research has been conducted on mice successfully, and with limited success in humans. Future research will likely focus on discovering the species-specific differences between mice and humans through studies with nonhuman primates. Research on large mammals such as the rhinoceros will also contribute to animal conservation efforts. While human IVG has not been fully developed yet, several concerns have arisen regarding the ethical and legal implications of this technology. While none of these concerns are tangible due to the current state of research findings and current International Society for Stem Cell Research guidelines, they may inform legislation in the future.

Entre os principais problemas relacionados ao manejo da vegetação nessa região, merece destaque a expansão da gramínea exótica Eragrostis plana Ness, que apresenta elevada capacidade de colonização dos campos naturais e tendência de exclusão da comunidade vegetal nativa. Algumas plantas são capazes de sintetizar determinados metabólitos secundários, liberados no ambiente e que podem interferir no ciclo de vida de outras plantas. A espécie Luehea divaricata Martius tem grande potencial para ser utilizada no controle do capim-annoni. O presente estudo objetivou avaliar o efeito de extratos de L. divaricata sobre a germinação, a emergência e o crescimento de plântulas de capim-annoni. Foram realizados dois experimentos: um em casa de vegetação para a avaliação da porcentagem de emergência (%E), índice de velocidade de emergência (IVE), comprimento da parte aérea e massa seca total de plantas; e outro em laboratório para a avaliação da porcentagem de germinação (%G), índice de velocidade de germinação (IVG), comprimento do sistema radicular. Os tratamentos utilizados foram: T1- água destilada; T2- extrato de L. divaricata 40 g.L-1 , T3- extrato de L. divaricata 80 g.L-1 e T4- extrato de L. divaricata 120 g.L-1 e o delineamento experimental foi o inteiramente casualisado. Os extratos de L. divaricata diminuem o índice de velocidade de emergência e comprimento do sistema radicular e aumentam o comprimento da parte aérea e massa seca total, não interferindo na porcentagem de germinação, porcentagem de emergência e índice de velocidade de germinação.

Belonging to the family Fabaceae, Sesbania punicia and S. virgata are characterized by their ecological potential in the recovery of degraded areas. The present study aimed to describe the physical, morphobiometric characteristics of seeds, the germination phases and the initial development of S. punicia and S. virgata seedlings, as well as the germination behavior of seeds at different temperatures and substrates. For the physical characterization of seeds, the weight of one thousand seeds, number of seeds per kilogram, dry biomass of one thousand seeds and the moisture content were determined. To evaluate the effect of substrate and temperature on germination, the experiment was conducted in a completely randomized design, using a 3 x 3 factorial scheme, three substrates (sand, vermiculite and blotting paper) and three temperatures (20, 25 and 30 °C). The following factors were evaluated: germination percentage, germination speed index, mean germination time and synchronization index. S. punicea presented 13,243 seeds and S. virgata presented 14,414 seeds per kilogram, with moisture content of 14.5 and 7.9%, respectively. Both species present similar morphobiometry and seedling development. For S. punicea, the blotting paper substrate and the temperature of 25 °C were most efficient for germination. For S. virgata, all treatments were effective for germination. [ABSTRACT FROM AUTHOR]

This paper explores whether egg donation could still be ethically justified if in vitro gametogenesis (IVG) became reliable and safe. In order to do this, issues and concerns that might inform a patient's reasoning in choosing to use donor eggs instead of IVG are explored and assessed. It is concluded that egg donation would only be ethically justified in a narrow range of special cases given the (hypothetical) availability of IVG treatment and, further, that egg donation could itself be replaced by donation through IVG techniques. Two possible criticisms of this position are then considered: Ones based on respect for patient wishes, and on loss of donor benefit. It is concluded that whilst neither argument constitutes a strong enough reason to continue with programmes of egg donation, egg‐sharing programmes could still be permitted come the advent of IVG; these could then provide a morally acceptable source of "natural" donor eggs.

Background: in France, there were 232,000 abortions in 2019. A large number of women have recourse to it several times during their lives. The provision of effective and appropriate post-abortion contraception is essential.Method: the objectives were to assess patients' satisfaction with their current contraception, at least three months post IVG, compared to their previous contraception, as well as to find out their opinion regarding their contraceptive follow-up. A qualitative descriptive and interpretative study was conducted with ten women, at least three months after their abortion.Results: women interviewed who had had abortion were generally satisfied with the contraceptive method used after their abortion. However, dissatisfaction persisted regarding the lack of information provided, contraceptive choice sometimes imposed and the weakness or absence of monitoring.Conclusion: to improve women's satisfaction, it might be interesting to devote more discussing time about contraceptive choice and to institute a monitoring after the new contraception has been introduced.; Introduction : en France, on comptait 232 000 avortements en 2019. Un grand nombre de femmes y ont recours plusieurs fois au cours de leur vie. La mise en place d’une contraception post-IVG efficace et adaptée est primordiale.Méthode : les objectifs étaient d’évaluer la satisfaction des patientes à propos de leur contraception actuelle, au moins trois mois post-IVG, en regard de leur contraception antérieure, ainsi que de connaître leur opinion concernant leur suivi de contraception. Une étude qualitative à visée descriptive et interprétative a été réalisée auprès de dix femmes, trois mois au minimum après leur IVG.Résultats : les femmes interrogées ayant vécu un avortement étaient globalement satisfaites du moyen de contraception utilisé après l’IVG. Cependant une insatisfaction persiste concernant le manque d’informations délivrées, le choix contraceptif parfois imposé et la faiblesse ou l’absence de suivi ultérieur.Conclusion : pour une meilleure satisfaction des femmes, il pourrait être intéressant de consacrer davantage de temps à l’échange autour du choix contraceptif et d’instaurer un suivi après la mise en place de cette nouvelle contraception.

Nanoscale zero-valent iron (nZVI) has been broadly applied in the remediation of heavy metals pollution. In this research, the toxicity characteristic leaching procedure (TCLP), the in vitro gastrointestinal (IVG) method, and the diffusive gradients in thin-films (DGT) technique were used to evaluate the effects of heavy metals in soil with remediation by nZVI. The results indicate that, compared with the dose of 0.5 g·L−1, the nZVI in the dose of 1.0 g·L−1 can remove the heavy metals in the soil. The leaching toxicities of the heavy metals (Cr, Cu, Zn, Pb) showed apparent decreases after the remediation by nZVI. In the gastric phase, the highest bioaccessibility values of the Cr, Cu, Zn, Pb were decreased by 27.2, 31.7, 11.7, and 20.1%, respectively. Moreover, in the gastric phase, the highest bioaccessibility values of the Cr, Cu, Zn, Pb were decreased by 5.5, 1.29, 8.0, and 7.3%, respectively. The availabilities of the heavy metals were also reduced. The above results show that the nZVI effectively reduced the heavy metal pollution in the soil.

Given the controversial nature of research into in-vitro gametogenesis (IVG), this study set out to investigate the current attitudes towards IVG in the general Belgian population in order to anticipate potential future barriers and misunderstandings. A questionnaire was developed and incorporated into a web-based online survey and sent out to Belgians aged ≥18 years in September 2018 until a representative sample (by age, gender and region) of 1000 participants was reached. Respondents expressed an overall positive attitude towards IVG and its possible future applications, with the exception of the use of IVG in postmenopausal women. They were ambivalent about the importance of genetic parenthood and about the necessary experiments on animals and embryos to bring IVG to the clinic. While the willingness to accept greater risks for IVG than for other assisted reproductive technology treatments was low (17.5%), the use of spare in-vitro fertilization embryos to study those risks was acceptable for 55.8% of participants; embryo creation was acceptable for 38.1%; and experiments on mice and monkeys were acceptable for 45.3% and 30.4%, respectively. Finally, 85.6% of participants agreed that the Belgian Government should strictly regulate IVG. In conclusion, preclinical research into IVG and other reproductive technologies elicits a great diversity of attitudes towards the importance of genetic parenthood and the acceptability of embryo and animal research. There is a need for public dialogue on these topics.

Depuis 1975, l’offre de soins en matière d’IVG a été améliorée pour remédier aux inégalités sociales et territoriales qui se font jour. En 2016, la loi a élargi le champ de compétence des sages-femmes à la prescription du dispositif médicamenteux. Dévalorisée par l’institution médicale, l’activité d’orthogénie est l’enjeu paradoxal d’une nouvelle lutte définitionnelle du territoire d’exercice des sages-femmes, dans le contexte des évolutions organisationnelles de la division du travail abortif, qui suscitent des controverses sur les finalités de leur activité. C’est au nom d’un care féminin que les sages-femmes s’emparent de cette pratique, tandis qu’une frange encore minoritaire investit l’espace des luttes féministes pour mener une mobilisation catégorielle destinée à faire reconnaître la légitimité du groupe professionnel dans la conduite de l’action publique en matière d’IVG. Ces militantes participent par là à l’émergence d’un nouveau segment, celui de la médecine orthogéniste.

Le 1er janvier 2022, la France comptait 67,8 millions d’habitants soit 187 000 de plus qu’au 1er janvier 2021. Les nombres de naissances, d’IVG et de mariages en 2021 ont augmenté si on les compare à 2020, sans toutefois retrouver les niveaux observés avant la crise sanitaire (2019). Il en est même pour les décès dont le nombre a diminué, mais reste encore supérieur à celui observé en 2019. En 2021, la France fait partie des 9 pays européens parmi les 27 dont le solde naturel est positif. Son solde migratoire l’est également et, en 2021, est supérieur au solde naturel. Au total, la population de la France continue d’augmenter, mais à un rythme plus faible qu’avant la pandémie. En 2020, les flux d’entrées de personnes venant de pays tiers avec un titre de séjour ont très fortement diminué du fait de la crise sanitaire. Ce sont les titres pour raison professionnelle qui ont le plus baissé. Les demandes se concentrent en Île-de-France. En 2021, l’indice conjoncturel de fécondité augmente très légèrement (1,83 enfant par femme), principalement du fait de la hausse des taux entre 30 et 39 ans. Le profil par âge varie selon les régions. Le recours à l’avortement est plutôt stable entre 2020 et 2021, mais la part des IVG réalisées par la méthode médicamenteuse augmente d’année en année (77 % en 2021), surtout celles pratiquées en cabinet de ville. Cependant, on observe d’importantes différences territoriales, du fait d’une offre de soins inégale au niveau local. En 2021, le rattrapage des mariages qui n’ont pu être célébrés en 2020 n’a été que partiel. Pour la première fois en 2020, le nombre de pacs dépasse celui des mariages. Les mariages sont plus fréquents sur le flanc est du pays et les pacs sur la façade atlantique et dans le Sud-Ouest. Le nombre de décès reste important en 2021 malgré une amélioration par rapport à 2020. L’espérance de vie en 2021 reste inférieure de 4,6 mois pour les hommes par rapport à 2019, et de 1,4 mois pour les femmes. La surmortalité est estimée à 6,3 % en 2021 après avoir été de 7,5 % en 2020. Les régions les plus touchées ne sont pas nécessairement celles où la mortalité était initialement forte.

The physic nut crop (Jatropha curcas L.) has been gaining some importance in the last years due to its use as a raw material for biodiesel production. The Physic nut can be propagated through stakes and/ or seeds. In this context, it was developed this study in order to evaluate the effects of the substrate, temperature and light on the germination and germination speed index (GSI) of physic nut seeds. The experimental design used was a factorial 4x2x2 with temperature (25, 30, 35 and 40 °C) x substrate (sand and paper) x light (presence and absence) with three replicates per treatment. The best germination percentages were obtained with the temperatures of 25, 30 and 35 °C with light and 30 ºC in light absence for the sand substrate and at a temperature of 30°C, whether in presence or absence of light for the paper substrate. The sowing in sand without light at 30 °C was that best promoted the seedling development with higher GSI. The combination of substrate between sand, temperature of 30 °C and absence of light showed the best condition for evaluating germination and GSI of physic nut seeds. A cultura do pinhão manso (Jatropha curcas L.) vem ganhando destaque nos últimos anos pelo seu uso como matéria prima para a produção de biodiesel. Sua reprodução pode ser realizada por estacas e/ou sementes. Neste contexto, se desenvolveu o presente estudo com o objetivo de avaliar o efeito do substrato, temperatura e luz sob a germinação e índice de velocidade de germinação (IVG) de sementes de pinhão manso. O delineamento experimental utilizado foi o fatorial do tipo 4x2x2 sendo quatro temperaturas (25, 30, 35 e 40 °C) dois substratos (areia e papel) e duas condições de luz (presença e ausência), com três repetições por tratamento. As maiores percentagens de germinação foram obtidas com as temperaturas de 25, 30 e 35 °C com luz e 30 ºC na ausência de luz para o substrato areia. Com a temperatura de 30 °C tanto na presença como na ausência de luz, para o substrato papel. A semeadura entre areia sem luz na temperatura de 30 °C foi a que melhor promoveu o desenvolvimento das plântulas, com maior IVG. A combinação do substrato entre areia, temperatura de 30 °C e ausência de luz é a melhor condição para avaliação da germinação e IVG de sementes de pinhão manso.

The objective of this study was to investigate the dynamics of mitochondrial activity in in vitro-grown (IVG) bovine oocytes during pre-maturational culture (pre-IVM) and its relationship to their developmental competence upon being subjected to different pre-IVM durations. After 12-day IVG culture, oocytes were cultured for 0, 10 or 20h with 3-isobutyl-1-methylxanthine (IBMX) as pre-IVM. Mitochondrial activity in IVG oocytes after 10h pre-IVM was the highest among all the pre-IVM durations (P<0.05). In addition, cleavage (79.4%) and blastocyst rates (38.9%) of embryos derived from IVG oocytes with 10h pre-IVM were higher than those with 20h pre-IVM (63.0 and 25.8%, respectively; P<0.05) and similar to those of in vivo-grown oocytes (82.7 and 36.7%, respectively). To confirm the developmental ability of IVG oocytes with 10h pre-IVM beyond the blastocyst stage in vivo, embryo transfer was attempted. Transferred embryos developed to the elongated embryonic stage (63.6%, 7/11) in the recipient uterus at Day 16 of oestrus, and a male calf was delivered (50%, 1/2). In conclusion, it was indicated that the mitochondrial activity of bovine IVG oocytes peaked at 10h pre-IVM and was closely correlated with the nuclear maturation and developmental competences of IVG oocytes.

France is one of the country with the highest contraceptive coverage. However, it is paradoxale that the rate of use of voluntary termination of pregnancy (abortion) remains stable and high. The contraceptive regimen has been the same for the last 10 years. First of all, the use of male condom at the beginning of sexual life, then the use of pills and finally the IUP when the desired number of children is reached. The average age of first sexual act in France is 17 years old while the average age for the first desired child is 29 years old. Therefore, those 12 years must be covered by an effective contraception. that includes the use of LARC methods (long-acting contraceptive) such as the IUD which seems to be suitable for reducing the risk of unwanted pregnancies. What's more, teenagers girls belong to a group at high risk of unwanted pregnancies. This statement is a big public health problem across the world. Therefore, improving education and access for teenagers girls to an effective contraception is a public health issue. This is what was proved by the CHOICE studies in US and FECOND in France. In spite of a wide use of male contraception during the first sexual acts (in 90% of cases in 15 to 24 year olds), zero impact has been observed on the number of abortions among teenagers girls. The reasons are multifactorial but the main cause would come from a lack of compliance and bad use of contraception means. Normally their theoretical effectiveness is around 99.7%. The CHOICE study showed that the use of LARC methods has a significant impact on reducing the number of unintended pregnancies among teenagers girls from 15 to 19 years old. What's more, there is a decrease in the use of abortion. As a result, multiple laws and recommendations established by French and international learned societies agree on the fact that the IUD is a contraception perfectly indicated for teenagers girls as well as for older women (nulliparous or multiparous). However, in France, the evolution of IUD use by teens remains low during the past 10 years. In fact, 57% of women surveyed by the FECOND study believe that the IUD is not recommended for nulliparous patients. 68% of gynecologists and 85% of general practitioners questioned by this study affirmed not to recommend the IUD in nulliparous or not to speak to them about it because of their own reluctance. However, it has been shown in the United States that women are three times more interested in the IUD after having received clear information. Yet, it is necessary that health professionals speak about the IUD to teens, in order to promotes their use. There is numerous reluctance the in the literature on the use of IUD by teens : increased risk of pelvic infection, fertility problem, higher risk of expulsion, poses more painful and more complex ... However, those reluctance have been controversial. There is a lot of barrier to use is the literature, but the main one remains a lack of information and knowledge. A lot of girls know the "IUD" without knowing its characteristics, indications or appearance. They are a long way from knowing that they can have it. The other main obstacle expressed is motivated by the various fears that the IUD arouses. Hence the importance of disclosing clear and complete information. There is a small quantity of lever certainly because of their significant ignorance about the IUD.; La France se place parmi les pays où le niveau de couverture contraceptive est le plus élevé. Or il existe un paradoxe puisque le taux de recours à l’interruption volontaire de grossesse (IVG) reste stable et élevé. Le schéma contraceptif reste le même depuis plus de dix années à savoir le recours au préservatif masculin au début de la vie sexuelle puis l’utilisation de la pilule et enfin le DIU lorsque le nombre d’enfants souhaité est atteint. L’âge moyen du premier rapport sexuel en France est de 17 ans et l’âge moyen du premier enfant désiré est de 29 ans ce qui laisse près de douze années de nulliparité à couvrir par une méthode contraceptive efficace, dont l’utilisation des méthodes LARC (contraceptif de longue durée d’action) telle que le DIU semble adapté pour réduire au mieux le risque de survenue de grossesses non désirées. En effet, les adolescentes appartiennent à un groupe à haut risque de survenue de grossesse non désirée ce qui pose un réel problème de Santé Publique à l’échelle mondiale. L’amélioration de l’éducation et de l’accès des adolescentes aux méthodes contraceptives efficaces est un enjeu de Santé Publique comme l’ont démontré les études CHOICE menée aux Etats Unis et FECOND en France. Effectivement malgré l’utilisation large d’une contraception lors des premiers rapports sexuels (préservatif masculin dans 90% des cas chez les 15 à 24 ans), aucun impact sur le nombre d’IVG chez les adolescentes n’a été réellement observé. Les raisons sont multi- factorielles mais la cause principale viendrait d’un défaut d’observance et d’une mauvaise utilisation des moyens de contraception dont l’efficacité théorique avoisine les 99,7%. L’étude CHOICE a montré que le recours aux méthodes LARC a un impact significatif sur la diminution du nombre de grossesses non désirées chez les adolescentes de 15 à 19 ans ainsi qu’une nette diminution du recours à l’IVG. En conséquence, de multiples lois et recommandations établies par les Sociétés Savantes françaises et internationales s’accordent sur le fait que le DIU est une contraception parfaitement indiquée aux adolescentes au même titre qu’aux femmes plus âgées (nullipares ou multipares). Or malgré cela l’évolution de l’utilisation du DIU par les adolescentes en France est faible en dix ans. 57% des femmes interrogées par l’étude FECOND pensent que le DIU n’est pas recommandé chez les nullipares. 68% des gynécologues et 85% des médecins généralistes interrogés par cette étude affirment ne pas recommander le DIU chez les nullipares voir ne pas leur en parler du tout du fait de leur propre réticence. Or il est montré aux Etats Unis que les femmes sont trois fois plus intéressées par le DIU après avoir reçu une information claire. Il est nécessaire que les professionnels de santé transmettent l’information aux adolescentes pour espérer promouvoir l’utilisation du DIU. On retrouve de nombreuses réticences à l’utilisation du DIU chez les plus jeunes dans la littérature : majoration du risque d’infection pelvienne, problème de fertilité, risque plus élevé d’expulsion, pose plus douloureuse et plus complexe... Toutes ces réticences ont été controversées. Nous avons retrouvé de nombreux freins similaires à ceux évoqués dans la littérature dont le principal est le manque d’information et de connaissances. Elles sont nombreuses à savoir citer le « stérilet » pour au final ne pas en connaître les caractéristiques, les indications ni les représentations. Elles sont bien loin de savoir qu’elles peuvent en bénéficier. L’autre principal frein exprimé est motivé par les différentes peurs que suscite le DIU d’où l’importance de divulguer une information claire et complète. Nous avons retrouvé très peu de levier certainement à cause de leurs importantes méconnaissances sur le DIU.

Extratos aquosos de folhas verdes de Nerium oleander L. Dieffenbachia picta nas concentrações 0; 0,0625; 0,125 e 0,25 mg/mL foram preparados com o objetivo de determinar o potencial alelopático dessas espécies utilizadas como plantas ornamentais, sobre sementes de Lactuca sativa (planta-teste) e Bidens pilosa L. O experimento foi conduzido durante o mês de janeiro de 2007, no Laboratório de Genética da Universidade Federal de Santa Maria. Foram avaliados a primeira contagem da germinação (PCG), germinação (G), o índice de velocidade de germinação (IVG), os comprimentos das raízes e da parte aérea e a biomassa fresca (MF). Ambas as espécies mostraram tendência a reduzirem os parâmetros morfológicos analisados a partir da concentração de 0,125 mg/mL, sendo que as sementes de Bidens pilosa L. foram mais sensíveis que às de alface. O IVG foi a variável que mostrou maior redução com o aumento da concentração dos extratos. A MF das plântulas de alface e Bidens pilosa L. foram reduzidas a partir da concentração de 0,0625 mg/mL. Ambos extratos mostraram atividade potencialmente alelopática.

An in vitro gastrointestinal model was used to explore the role of solid–liquid separation method on the bioaccessibility of trace elements in a smelter-impacted soil (NIST-2711) from Helena, MT and a mine overburden from an open-pit gold and silver mine in Mount Nansen, YK (YK-OVB). Separation methods studied included centrifugation (5000 g , 12 000 g ), syringe microfiltration (0.45 μm), and ultrafiltration (1000 kDa, 50 kDa, 30 kDa, 10 kDa, 3 kDa). Results indicated that the use of syringe microfiltration generally yields the same bioaccessibility as the use of centrifugation and that the speed of centrifugation does not typically affect metal bioaccessibility. However, ultrafiltration consistently yields a significantly lower bioaccessibility than the use of centrifugation and syringe microfiltration. There are rarely any differences between bioaccessibility estimates generated using a low-resistance (1000 kDa) and a high-resistance (3 kDa) ultrafiltration membrane; therefore, under the in vitro gastrointestinal conditions modeled herein, negligible quantities of trace elements are complexed to small molecules between 3 and 1000 kDa. The primary exceptions to these trends were observed for Pb in NIST-2711 (5000 g > 12 000 g > 0.45 μm > ultrafiltration) and for Tl in NIST-2711 and YK-OVB (5000 g ∼ 12 000 g > 0.45 μm > ultrafiltration). These results provide valuable information to researchers attempting to expand the use of in vitro bioaccessibility beyond soil Pb and As. [ABSTRACT FROM AUTHOR]

Objectif : depuis 2004, les médecins généralistes libéraux peuvent pratiquer l’interruption volontaire de grossesse (IVG) par méthode médicamenteuse en cabinet, jusqu’à 7 SA. En 2018, sur 224 300 IVG, 69% ont été réalisées par voie médicamenteuse, et seulement 24% hors secteur hospitalier. En PACA, 3ème région ayant le plus fort taux d’IVG, 1/3 des IVG a été réalisé hors secteur hospitalier. En cabinet libéral, cela représente seulement 4% de gynécologues et généralistes libéraux. Nous avons ainsi cherché à évaluer la pratique et les connaissances des médecins généralistes du Vaucluse en matière d'IVG ainsi que les barrières qui peuvent freiner sa pratique.Méthodologie : une étude quantitative descriptive a été réalisée grâce à un auto-questionnaire envoyé par mail à 106 médecins généralistes du Vaucluse, pratiquant ou non l’IVG, entre mai et juin 2020. Ce questionnaire évaluait le profil socio démographique des médecins, l’intérêt de l’IVG en médecine générale, les connaissances et modalités de pratique effectives de l’IVG par les généralistes, les motivations et freins potentiels ou avérés, et les perspectives de développement de cette activité.Résultats : 43 médecins ont répondu au questionnaire, soit un taux de réponse de 40.5%. Au sein de cet échantillon 23% des généralistes pratiquent l’IVG. 76% des praticiens qui ne la pratiquent pas considèrent qu’elle fait partie du champ d’action de la médecine générale, 24% estiment qu’elle implique cependant trop d’inconvénients. Les pratiques et les connaissances sur l’IVG sont hétérogènes et sont parfois obsolètes ou s’écartent des recommandations. Peu de médecins se sentent suffisamment informés sur l’IVG (15%). Cette activité représente cependant une source de motivation, principalement pour améliorer l’accès à l’IVG et diminuer les délais de prise en charge. Les généralistes qui la pratiquent, sont majoritairement freinés par la faible demande des patientes, son caractère contraignant et stressant et son manque de visibilité par le public. Ceux ne la pratiquant pas mentionnent principalement la bonne organisation du système de soins, son côté contraignant et stressant, son caractère chronophage, et le manque d’expérience. Plusieurs pistes de développement sont soulevées et semblent particulièrement importantes, parmi elles : l’amélioration de l’accès à la formation, de la visibilité du réseau de professionnels et des connaissances des généralistes sur le sujet.Conclusion : le système de soins dans le Vaucluse autour de l’IVG semble bien organisé, réduisant la nécessité pour les médecins de se former. L’évaluation du vécu des patientes sur ce point serait intéressante, et pourrait expliquer la faible sollicitation auprès de leur généraliste. Un travail sur la visibilité du réseau des professionnels par le public et par les praticiens, ainsi qu’une meilleure formation des médecins et une meilleure éducation du grand public semblent indispensables à la mobilisation des généralistes pour cette activité. Cela peut s’intégrer dans la mise en place d’un réseau dédié à l’IVG, à l’image de ce qui existe déjà dans d’autres régions (REVHO).

La sanción de la ley de interrupción voluntaria del embarazo impactó en el Código Penal Argentino produciendo cambios de significativa trascendencia. Desde la corrección del momento de inicio de la protección jurídico penal de la vida, hasta la virtual no punibilidad de la muerte del feto cuando es practicada o consentida por la persona gestante, pasando por la derogación del aborto profesional y la incorporación de la dilación, obstaculización o negativa del funcionario público o personal de salud en practicar un aborto, la nueva ley toma posición clara en el conflicto entre la vida del feto y la autonomía de la persona gestante en favor de la libertad de decisión de ella., La sanction de la loi sur l’interruption volontaire de grossesse a eu un impact sur le Code Pénal Argentin, produisant des changements d’une importance significative. De la correction du moment de l’initiation de la protection juridique pénale de la vie, à la quasi-non-punition de la mort du foetus lorsqu’elle est pratiquée ou consentie par la personne enceinte, en passant par l’abrogation de l’avortement professionnel et l’incorporation de retard, obstruction ou refus de l’agent public ou du personnel de santé de pratiquer un avortement, la nouvelle loi prend clairement position dans le conflit entre la vie du foetus et l’autonomie de la personne enceinte au profit de sa liberté de décision., Facultad de Ciencias Jurídicas y Sociales

Résumé: Objectif: En France, la contraception est accessible pour tous, pourtant, le nombre d’interruption volontaire de grossesse (IVG) ne régresse pas, notamment chez les jeunes. Le but de notre étude est d’analyser, dans le contexte guadeloupéen, les caractéristiques de la population des mineures demandeuses d’une IVG. Méthodes: Cette étude rétrospective analyse les caractéristiques sociodémographiques et médicales de 129 mineures ayant bénéficié d’une IVG en 2010, dans notre centre d’orthogénie. Pour 67 d’entre elles, les résultats d’entretien avec la psychologue sont aussi rapportés. Résultats: Issues préférentiellement de familles nombreuses monoparentales, ces jeunes filles avaient un âge moyen de 15,9ans (±1,12), 96,1 % étaient nées en France, 10,9 % avaient déjà eu une grossesse, 67,2 % avaient un partenaire majeur et 64,4 % utilisaient une contraception avant l’IVG. Les motivations premières de l’IVG étaient la poursuite des études et le jeune âge ; 55,1 % de ces demandes survenaient après neuf semaines d’aménorrhée et 43,3 % des patientes rapportaient des difficultés d’ordre psychologique liées à l’IVG. Conclusion: À partir de ce profil type, notre étude propose des éléments de réflexion susceptibles d’aider à la lutte contre les grossesses non désirées dans cette population particulière des mineures.

Research questionThe economic and reproductive medicine response to the coronavirus disease 2019 (COVID-19) pandemic in the USA has reduced the affordability and accessibility of fertility care. What is the impact of the 2008 financial recession and the COVID-19 recession on fertility treatments and cumulative live births?DesignThe study examined annual US natality, Centers for Disease Control and Prevention IVF cycle activity and live birth data from 1999 to 2018 encompassing 3,286,349 treatment cycles, to estimate the age-stratified reduction in IVF cycles undertaken after the 2008 financial recession, with forward quantitative modelling of IVF cycle activity and cumulative live births for 2020 to 2023.ResultsThe financial recession of 2008 caused a 4-year plateau in fertility treatments with a predicted 53,026 (95% confidence interval [CI] 49,581 to 56,471) fewer IVF cycles and 16,872 (95% CI 16,713 to 17,031) fewer live births. A similar scale of economic recession would cause 67,386 (95% CI 61,686 to 73,086) fewer IVF cycles between 2020 and 2023, with women younger than 35 years overall undertaking 22,504 (95% CI 14,320 to 30,690) fewer cycles, compared with 4445 (95% CI 3144 to 5749) fewer cycles in women over the age of 40 years. This equates to overall 25,143 (95% CI 22,408 to 27,877) fewer predicted live births from IVF, of which only 490 (95% CI 381 to 601) are anticipated to occur in women over the age of 40 years.ConclusionsThe COVID-19 recession could have a profound impact on US IVF live birth rates in young women, further aggravating pre-existing declines in total fertility rates.

International audience; Inapplicability of the rule of law may sometimes result from some kind of resistance to the rule by the people who are supposed to enforce it. This resistance can sometimes be based on a real right that the law recognizes, in the form of conscientious objection, namely by the possibility recognized to the individual who is supposed to apply the norm, to refuse to do so, if the content of this norm hurts his personal convictions, his conscience. The use of conscientious objection may, however, not remain an isolated phenomenon, but acquire a certain quantitative importance and it may happen that this situation leads to a real inapplicability of the rule of law.As part of this study, a case of serious non-application of the rule of law due to a massive use of the conscience clause by health personnel will be presented and analyzed, namely the inapplicability of the Italian law 194 of May 22, 1978 opening the access of women to abortion. By noting that Italy is not the only country experiencing such difficulties, especially at a time when lawmakers can no longer escape complex and delicate ethical choices, such as those concerning euthanasia or the assisted reproduction’s same-sex couples, this study is an opportunity to reflect on the theme of conscientious objection and its conciliation with other rights guaranteed by the legislator.; L’inapplication de la règle de droit peut parfois résulter d’une sorte de résistance opposée à la règle par les personnes qui sont censées en assurer l’application. Cette résistance peut parfois se fonder sur un véritable droit que la loi reconnaît, sous la forme de l’objection de conscience, à savoir par la possibilité reconnue à l’individu qui est censé appliquer la norme, de refuser de le faire, si le contenu de cette norme heurte ses convictions personnelles, sa conscience. Le recours à l’objection de conscience peut toutefois ne pas demeurer un phénomène isolé, mais acquérir une certaine importance quantitative et il peut arriver que cette situation aboutisse à une véritable inapplication de la règle de droit. Dans le cadre de cette étude, sera présenté et analysé un cas d’inapplication grave de la règle de droit dû à un recours massif à la clause de conscience de la part des personnels de santé, à savoir l’inapplication de la loi italienne n. 194 du 22 mai 1978 ouvrant l’accès des femmes à l’interruption volontaire de grossesse. En constatant que l’Italie n’est pas le seul Pays à connaître ce genre de difficultés, surtout à une époque où les législateurs ne peuvent plus échapper à des choix éthiques complexes et délicats, comme ceux qui concernent l’euthanasie ou la PMA pour les couples du même sexe, cette étude est une occasion de réfléchir autour du thème de l’objection de conscience et de sa conciliation avec d’autres droits garantis par le législateur.

The rate of abortion in France has remained stable for several years, despite increasing availability of contraception and emergency contraception (EC).Main objective: to assess the knowledge and information sources of women aged 18 to 35 on EC.Methods: descriptive, prospective, multicentric study with descriptive analysis of the responses then bi-varied analysis by Chi-2 test. Included women were between 18 and 35 years old, consulting in general medicine between June and October 2018 in Île-de-France.Results: 300 patients were included, the mean age was 26 years, 69% of patients had regular contraception, 16% had had an abortion and 57% had already used EC. Only 49% of patients had already been informed by their GP about EC. Free access to pharmacy was generally well known. The types of EC, their time of effectiveness and the absence of serious side effects were, however, not well known. The Internet was the main source of information cited before pharmacists and general practitioners (66.3%, 62.3% and 62% respectively). Study level, prior information on EC and abortion appeared to be determinative of EC use and patient knowledge.Conclusion: patients' knowledge of EC remains to be improved, as is their information in general medical consultation. For this, it seems necessary to continue training doctors and continue to raise awareness among the general public.; Le taux d’IVG en France reste stable depuis plusieurs années et ce malgré une accessibilité croissante à la contraception et à la contraception d’urgence (CU).Objectif principal : évaluer les connaissances et les sources d’information des femmes de 18 à 35 ans sur la CU.Méthodes : étude descriptive, prospective, multicentrique avec analyse descriptive des réponses puis analyse bi-variée par test du Chi-2. Étaient incluses les femmes âgées de 18 à 35 ans consultant en médecine générale entre juin et octobre 2018 en Île-de-France. Résultats : 300 patientes ont été incluses, l’âge moyen était de 26 ans, 69% des patientes avaient une contraception régulière, 16% avaient eu une IVG et 57% avaient déjà eu recours à une CU. Seules 49% des patientes avaient déjà été informées par leur médecin traitant sur la CU. Le libre accès en pharmacie était globalement bien connu. Les types de CU, leur délai d’efficacité et l’absence d’effet secondaire grave étaient par contre méconnus. Internet était la principale source d’information citée devant les pharmaciens et les médecins généralistes (respectivement 66.3%, 62.3% et 62%). Le niveau d’étude, l’information préalable sur la CU et l’IVG semblaient déterminants sur le recours à la CU et les connaissances des patientes. Conclusion : les connaissances des patientes sur la CU restent à améliorer tout comme leur information en consultation de médecine générale. Pour cela, il semble nécessaire de poursuivre la formation des médecins et de continuer la sensibilisation du grand public.

A pitaya é uma cactácea epífita que tem seu centro de origem nas Américas e vem sendo cultivada em vários países do mundo. É também conhecida como “fruta dragão” pelo aspecto escamoso de seu fruto. O potencial desta frutífera tanto para mercado interno quanto externo, tem despertado o interesse de muitos produtores brasileiros. A pitaya vermelha Hylocereus undatus vem se destacando como a preferida do consumidor principalmente pela coloração de seus frutos. O aumento do seu plantio tem gerado uma grande demanda por produção de mudas e embora os métodos convencionais para propagação cactos sejam satisfatórios as pesquisas têm mostrado que, independentemente da espécie, o suprimento adequado em água, nutrição, temperaturas convenientes, assim como luminosidade, são requisitos fundamentais para a germinação. Quando esta ocorre in vitro, a composição do meio nutritivo assim como as substâncias nele adicionadas irão favorecer a germinação e otimizar seu processo. Estudos de meios de cultura que favoreçam a germinação in vitro desta espécie são importantes tanto para maximizar a taxa de germinação, como para obter plântulas com qualidade genética e fitossanitária adequada. Além dos aspectos que envolvem a germinação, a cultura de tecidos se apresenta como uma ferramenta auxiliar na obtenção de um grande número de plantas sadias, de alta qualidade, em pequeno espaço físico e em curto espaço de tempo, atendendo assim a demanda dos produtores para por mudas. Neste contexto, o presente trabalho objetivou avaliar a germinação in vitro de sementes de pitaya vermelha Hylocereus undatus

- Abstract
Nanoscale zero-valent iron (nZVI) has been broadly applied in the remediation of heavy metals pollution. In this research, the toxicity characteristic leaching procedure (TCLP), the in vitro gastrointestinal (IVG) method, and the diffusive gradients in thin-films (DGT) technique were used to evaluate the effects of heavy metals in soil with remediation by nZVI. The results indicate that, compared with the dose of 0.5 g·L
−1 , the nZVI in the dose of 1.0 g·L−1 can remove the heavy metals in the soil. The leaching toxicities of the heavy metals (Cr, Cu, Zn, Pb) showed apparent decreases after the remediation by nZVI. In the gastric phase, the highest bioaccessibility values of the Cr, Cu, Zn, Pb were decreased by 27.2, 31.7, 11.7, and 20.1%, respectively. Moreover, in the gastric phase, the highest bioaccessibility values of the Cr, Cu, Zn, Pb were decreased by 5.5, 1.29, 8.0, and 7.3%, respectively. The availabilities of the heavy metals were also reduced. The above results show that the nZVI effectively reduced the heavy metal pollution in the soil. [ABSTRACT FROM AUTHOR]- Published

Abstract: Objective: The goal of this work was to determine the influences exerted on minors during a request for voluntary termination of pregnancy (TOP). Patients and methods: We made a retrospective descriptive study at the Centre Hospitalier Universitaire (CHU) of Nice. Two hundred (and) four minor patients were included, from January 1st 2003 to December 31st 2004. Results: In the majority of cases, the entourage (sexual partner or parents) who are informed of the request for TOP support the patient in her choice. In more than 56% of cases, the parents are not informed of the request for TOP. Discussion and conclusion: It seems, for minors, that it is the need for conforming to the existing social model which motivates the majority of the requests for TOP. [Copyright &y& Elsevier]

Entre os principais problemas relacionados ao manejo da vegetação nessa região, merece destaque a expansão da gramínea exótica Eragrostis plana Ness, que apresenta elevada capacidade de colonização dos campos naturais e tendência de exclusão da comunidade vegetal nativa. Algumas plantas são capazes de sintetizar determinados metabólitos secundários, liberados no ambiente e que podem interferir no ciclo de vida de outras plantas. A espécie Luehea divaricata Martius tem grande potencial para ser utilizada no controle do capim-annoni. O presente estudo objetivou avaliar o efeito de extratos de L. divaricata sobre a germinação, a emergência e o crescimento de plântulas de capim-annoni. Foram realizados dois experimentos: um em casa de vegetação para a avaliação da porcentagem de emergência (%E), índice de velocidade de emergência (IVE), comprimento da parte aérea e massa seca total de plantas; e outro em laboratório para a avaliação da porcentagem de germinação (%G), índice de velocidade de germinação (IVG), comprimento do sistema radicular. Os tratamentos utilizados foram: T1- água destilada; T2- extrato de L. divaricata 40 g.L-1 , T3- extrato de L. divaricata 80 g.L-1 e T4- extrato de L. divaricata 120 g.L-1 e o delineamento experimental foi o inteiramente casualisado. Os extratos de L. divaricata diminuem o índice de velocidade de emergência e comprimento do sistema radicular e aumentam o comprimento da parte aérea e massa seca total, não interferindo na porcentagem de germinação, porcentagem de emergência e índice de velocidade de germinação.

In Mexico, there is a wider conservative tradition compared to other nations. However, in order to know with precision the evolution of social thought on topics that tend to polarize opinions, we must listen not only to opinion leaders' arguments in favor and against, but also measure the way in which citizens take positions. In this study, approval or disapproval of euthanasia, abortion and the "day after" pill is addressed. Results show that 64% of this Mexican sample would agree to the existence of euthanasia as an alternative for those who suffer from terminal diseases. The greater approval of this topic is represented by individuals with higher education levels. In terms of abortion, 59% of Mexicans agree that a woman has the right to interrupt her own pregnancy. Young citizens and citizens with higher levels of education are the ones who support this measure and a greater proportion of men than women approve of its legislation. A 79% of Mexicans approve of the "day after" pill, specially in the younger and more educated sectors of the population. [ABSTRACT FROM AUTHOR]

Interruption volontaire de grossesse ,Contraception ,IVG ,Défaveur sociale ,[SDV.MHEP]Life Sciences [q-bio]/Human health and pathology - Abstract
The rate of multiple abortions is rising these last decades especially for the socially disadvantaged women. It would be interesting to identify their expectations and needs regarding the prescription of contraception to meet them better.A qualitative research with an interview guide allowed us to realize thirteen semi-directive individual meetings, eight in face to face and five over the phone. The interviewees have been selected among independent general practitioners and midwives and in the orthogenic center of the hospital Archet in Nice based on socio-economics criteria. Socially disadvantage women tend to not remember the medical information about their contraception ask few questions, not so much get involved in their management, use internet to learn and underestimate the pregnancy risk.They are expecting from the healthcare professionals to be guided towards reliable sources of information, detailed information about sides effects, medical consultations in which they are motivated to actively get involved in their own management, a more supported awareness about unintended pregnancy and the importance of good compliance, a reminder about the availability of an emergency contraception and lastly a doctor provider of information, prescriber and partner in their contraceptive course. They are also expecting a better consideration of their priorities in their contraception choices which are efficiency, safety, comfort in use for a better compliance and the cost.; On constate ces dernières décennies une augmentation du recours à l’IVG multiple qui concerne surtout les femmes de catégories socio-économiques défavorisées. Il serait intéressant d’identifier les attentes et besoins des patientes socialement défavorisées quant à la prescription de la contraception post IVG afin d’y répondre au mieux. Une étude qualitative avec guide d’entretien nous a permis de réaliser treize entretiens individuels semi directifs dont huit de visu et cinq téléphoniques. Les enquêtées ont recrutées auprès des patientèles de médecins généralistes et sages-femmes libéraux mais aussi au centre d’orthogénie du CHU de l'Archet à Nice selon des critères socio-économiques. Les femmes socialement défavorisées ont tendance à peu retenir les informations médicales sur leur contraception, à poser peu de questions et à peu s’impliquer dans leur prise en charge, à utiliser internet pour s’informer et à sous-estimer le risque de grossesse.Elles attendent des professionnels de santé : une orientation vers des sources d’informations fiables, des informations plus précises sur les effets indésirables potentiels des contraceptifs, une consultation où elles sont motivées à s’impliquer activement dans leur prise en charge, une sensibilisation plus appuyée sur le risque de grossesse et l’importance d’une bonne observance, un rappel sur la disponibilité d’une contraception d’urgence et enfin d’un médecin généraliste pourvoyeur d’informations, prescripteur et un partenaire dans leur parcours contraceptif. Elles attendent également une prise en compte de leurs priorités dans le choix d’une contraception qui sont l’efficacité, l’innocuité, le confort d’utilisation pour une meilleure observance et enfin le coût.

More than forty years after its legalization and regulation, challenges in accessing abortion endure in France, with significant territorial disparities. Among other things, the offer for instrumental abortion is shrinking, thus limiting the choice of method for women. The objective of this study was to analyze the opening of midwives' area of proficiencies to instrumental abortion in response to this public health problem. Sixteen semi-directive interviews were conducted with orthogenist midwives between October 2018 and January 2019. Our analysis shows that most of these midwives were in favor of integrating instrumental abortion into their professional skills. They define themselves as practitioners capable of performing this procedure, with the objective of improving access to abortion for women and providing comprehensive care for women throughout their reproductive lives. However, technical, organizational and personal concerns were raised. Conferring this practice to midwives would increase the offer of instrumental abortion care, which has been steadily decreasing since 2001, and thus broaden the choice of method for women.The introduction of a stakeholder traditionally associated with gestation could consolidate the image of abortion as an integral part of women's lives.; Plus de quarante ans après sa légalisation, des difficultés d’accès à l’IVG persistent en France, avec de fortes disparités territoriales. Entre autres, l’offre de soins en matière d’IVG instrumentale s’amenuise, et restreint ainsi le choix de la méthode pour les femmes. L’objectif de cette étude était de s’interroger sur l’ouverture du champ de compétences des sages-femmes à l’IVG instrumentale, en réponse à un problème de santé publique.Seize entretiens semi-directifs ont été réalisés auprès de sages-femmes orthogénistes, entre octobre 2018 et janvier 2019. Notre analyse a montré que ces sages-femmes étaient majoritairement favorables à l’intégration de l’IVG instrumentale à leurs compétences. Elles se définissent elles-mêmes comme praticiennes aptes à réaliser ce geste, dans un objectif d’amélioration de l’accès à l’IVG pour les femmes et de prise en charge globale de la femme tout au long de sa vie génésique. Toutefois, des appréhensions techniques, organisationnelles, mais aussi personnelles ont été soulevées. Accorder cette pratique aux sages-femmes pourrait permettre d’accroître l’offre de soins des IVG instrumentales en constante diminution depuis 2001, et ainsi d’élargir le choix de la méthode pour les femmes. L’introduction d’une profession traditionnellement associée auparcours gestatif pourrait consolider l’image de l’IVG comme faisant partie intégrante de la vie des femmes.
