RESUMO

BACKGROUND: Toxoplasmosis not only leads to abortion in humans but also in herbivores, which causes significant financial and quality-adjusted life-year losses. The present study aimed to determine the prevalence of toxoplasmosis in aborted fetuses via serological and molecular assays. Moreover, the genotypes of the obtained isolates were detected. METHODS: Serological and molecular methods were used to study aborted fetuses from Bojnourd City, North Khorasan Province, Iran, which included 52 ovines and 16 bovines. Nested PCR of the B1 gene was used to detect parasite DNA in brain tissues. The PCR-RFLP method for the GRA6 gene was used to determine the genotype of T. gondii. RESULTS: Out of 68 aborted fetuses, 16.1% showed the presence of anti-T. gondii IgG. Among these, 11.7% were identified in bovine fetuses and 4.4% in ovine fetuses. Additionally, two (2.94%) samples of ovine tested positive for anti-T. gondii IgM. Our PCR analysis detected parasite DNA in two cases (2.94%) among 11 IgG-positive samples. All obtained isolates belong to type I of T. gondii. CONCLUSION: Infection with Type I of T. gondii during the neonatal period may partly be responsible for abortion and economic losses in livestock farming in our studied region. To understand the molecular epidemiology and genotypes of T. gondii associated with abortion, further evaluation of aborted samples from different geographical locations is necessary.

RESUMO

Seed development is an essential phenomenon for all sexual propagative plant species. The functional allele at SEED DEVELOPMENT 1 (SDV1) or SEED DEVELOPMENT 2 (SDV2) loci is essential for seed development for Oryza sativa and Oryza meridionalis. In the present study, we performed fine mapping of SDV1, narrowing down the area of interest to 333kb on chromosome 6. Haplotype analysis around the SDV1 locus of O. meridionalis accessions indicated that they shared the DNA polymorphism, suggesting that they have a common abortive allele at the SDV1 locus. Linkage analysis of the candidate SDV2 gene showed that it was located on chromosome 4. The candidate SDV2 was confirmed using a population in which both the SDV1 and SDV2 genes were segregating. The chromosomal region covering the SDV1 gene was predicted to contain 30 protein-coding genes in O. sativa. Five of these genes have conserved DNA sequences in the chromosomal region of the SDV2 gene on chromosome 4, and not on chromosome 6, of O. meridionalis. These results suggest that these five genes could be candidates for SDV1, and that their orthologous genes located on chromosome 4 of O. meridionalis could be candidates for SDV2.

RESUMO

Introduction: Semen Cuscutae is a traditional Chinese medicine (TCM) that tonifies the kidneys and prevents miscarriage. According to Chinese medicine theory, kidney deficiency is one of the main causes of recurrent spontaneous abortion (RSA). The previous studies showed that raw product of Semen Cuscutae (SP) and Semen Cuscutae processed with salt solution (YP) have ameliorative effects on RSA, and that YP is superior to SP. However, the active components of YP to ameliorate RSA remain unclear and require further studies. The objective of this study is to investigate the active components of YP in ameliorating RSA. Methods: First, a rat model of RSA was established using hydroxyurea in combination with mifepristone. Aqueous decoction of YP was given by gavage to rats. Second, pregnant rats were sampled on days 5, 7, 9, 10 and 12 during the modelling period. The content of Hyperin (HY), astragalin (AS) and kaempferol-3-O-ß-D-glucuronide (KA) in blood and liver, heart, spleen, lung and kidney tissues were detected by liquid chromatography-mass spectrometry (LC-MS). The pharmacodynamic indicators including progesterone (P), chorionic gonadotropin ß (ß-HCG), estradiol (E2), tumor necrosis factor-α (TFN-α), interleukin 4 (IL-4), and tryptophan (TRP) were measured by enzyme-linked immunosorbent assay (ELISA) Pearson's correlation analysis and grey relational analysis were used to establish the relationship between the pharmacodynamic indexes and chemical constituents. Results: The pharmacokinetic results showed that the area under curve (AUC) value of KA was the largest. The tissue distribution results showed that astragalin was widely distributed in liver, heart, spleen, lung and kidney in the RSA model rats, while HY was detected only in the uterus, and KA was detected only in the kidney. The pearson correlationl analysis showed that KA was significantly and positively correlated with the contents of E2, P, ß-HCG and TRP. Both AS and HY were significantly negatively correlated with the content of TNF-α, respectively. Discussion: This study reveals the pharmacokinetics and tissue distribution of KA, AS and HY in rats with RSA. It was elucidated that all three were involved in the regulation of progesterone levels and immune function. It initially revealed the mechanism of action of YP in enhancing the improvement of RSA, and it provided a theoretical basis for the quality assessment of YP.

RESUMO

AIMS: Assess the psychological impact that providing TOP care beyond 12 weeks gestation has on midwives in Australia and New Zealand, improve understanding of TOP care and explore what support midwives have and what they might need to deal with their work experiences. DESIGN: Online survey. METHODS: A web-based, self-reported questionnaire with a total of 63 questions collected data from June to October 2022. Two validated psychometric tools were included to assess emotional well-being. Numerical data were analysed using descriptive statistics, frequencies, percentages and means. The STROBE guideline was used for reporting. RESULTS: Most midwives felt unsupported and affected by their experiences of providing termination of pregnancy care. Recognition and regular post-care debriefing with management were minimal. Lack of staff impacted the ability to provide individualised care. Mental health support was not commonly offered to midwives. Psychometric tools showed burnout and high levels of compassion fatigue, but also compassion satisfaction. To feel supported midwives need a fully staffed workforce, the ability to provide one-on-one care, recognition from managers and team support. CONCLUSION: Midwives who deliver termination of pregnancy care are unsupported and at high risk of burnout and compassion fatigue. Providing appropriate support is vital to increase midwives' well-being and sustain women's access to safe, high-quality care. IMPACT: Study addresses a knowledge gap about midwives' support needs when caring for women undergoing termination of pregnancy beyond 12 weeks. Findings show the urgent need to recruit and retain midwifery staff, acknowledge the mental health risks of termination of pregnancy care and implement mental health strategies for midwives. Research benefits midwives who provide termination of pregnancy care, midwife managers, healthcare organisations and professional bodies. PATIENT OR PUBLIC CONTRIBUTION: No patient or public involvement.

RESUMO

Background: Anaemia, characterized by low red blood cell or haemoglobin levels, impairs oxygen transport in the body and poses a major global public health issue, particularly affecting pregnant women and children. This study focuses on identifying the factors contributing to anaemia among pregnant women receiving antenatal care (ANC) at Mizan-Tepi University Teaching Hospital (MTUTH) in southwest Ethiopia. Methods: A hospital-based unmatched case-control study was conducted from July 1 to August 30, 2022, involving 370 pregnant women (90 with anaemia and 280 without). Data collection included questionnaires, laboratory tests (Hgb and stool examination), and anthropometric measurements. SPSS version 21 was used for data analysis, with binary logistic regression identifying factors associated with anaemia. The significance level was set at a p-value <0.05. Results: The study achieved a 100% response rate for both cases and controls. Factors identified as determinants of anaemia among pregnant women included malaria infection (AOR = 7.83, 95% CI: 3.89-15.8), hookworm infection (AOR = 2.73, 95% CI: 1.39-5.34), short birth interval (AOR = 7.11, 95% CI: 3.59-14.2), and history of unsafe abortion (AOR = 5.40, 95% CI: 2.46-11.8). Conclusion: This study found that malaria infection, hookworm infection, birth interval <33 months, and a history of unsafe abortion are factors contributing to anaemia in pregnant women. Strategies such as distributing insecticide-treated bed nets (ITNs) to combat malaria, improving sanitation, anthelmintic drugs, promoting family planning to prevent unwanted pregnancies and unsafe abortions, and providing preconception care can help reduce the incidence of anaemia.

RESUMO

Background: The COVID-19 pandemic created a massive shift in how health care systems interact with COVID testing for patients. To avoid delay in accessing second trimester surgical abortion at our hospital (St. Paul's Hospital Millennium Medical College) during this pandemic, dilation and evacuation (D&E) procedures were attended as emergency cases, instead of as elective surgical procedures, which then required adherence to the universal preoperative COVID-19 testing protocol. This study aimed at documenting the experience of this unique abortion service adjustment in response to the COVID-19 pandemic. Methods: This was a retrospective descriptive study conducted at St. Paul's Hospital Millennium Medical College (SPHMMC) in Addis Ababa, Ethiopia, from April 1, 2021 to July 31, 2021. We reviewed second trimester surgical abortion cases managed with D& E procedures, performed under spinal anesthesia using the emergency COVID-19 pre-operative testing protocol. Data were analyzed using SPSS version 23 and simple descriptive statistics were applied. Percentages and proportions were used to present the results. Results: Nineteen cases of second trimester D&E cases were reviewed. The median gestational age of the abortion clients was 21.57 weeks. Eight of 19 cases had cervical preparation with overnight intra-cervical Foley catheter placement while the rest 11 (57.9%) cases had their cervical preparation with Laminaria. The median time interval from initial evaluation of the abortion client to time of doing D& E procedure was 21.83 h. Conclusion: Surgical abortion service reorganization enabled abortion clients to access dilation and evacuation procedures within 24 h of their initial presentation. This prevented significant delays in accessing abortion care that could otherwise have occurred as a result of adhering to the preoperative COVID-19 testing protocols applied to elective surgeries.

RESUMO

Objective: This study investigates the thromboelastography (TEG) changes in patients with unexplained recurrent spontaneous abortion (URSA) to identify effective diagnostic markers for URSA. Methods: We retrospectively analyzed 160 URSA patients from the Gynecology Department of the First People's Hospital of Lianyungang (June 2017 - June 2020) and compared them with 190 healthy, fertile women without adverse pregnancy histories (control group). TEG parameters were assessed using logistic regression, applying stepwise selection for model optimization. Model performance was evaluated using Receiver Operating Characteristic (ROC) curves, determining sensitivity and specificity. The Youden index identified optimal cut points for predictive probabilities. Results: Significant differences were observed between the URSA and control groups in coagulation reaction time (R), clot formation time (K), clot formation rate (Angle-α), and maximum clot strength (MA) (P<0.05). Multivariable logistic regression identified R, Angle-α, and MA as independent URSA risk factors. The model demonstrated excellent discrimination (AUC: 0.940; 95% CI: 0.918-0.962). The optimal cut point of predictive probability (Youden index) was P=0.355, yielding a sensitivity of 0.925 and specificity of 0.795. Conclusion: URSA patients exhibit a hypercoagulable state even when not pregnant. More research is needed to validate our findings and explore the potential clinical implications of anticoagulants in treating URSA.

RESUMO

KEY MESSAGE: Embryo abortion at the heart-shaped stage is the main reason for the failure of interspecific hybridization of hydrangea, and salicylic acid plays a key role during embryo abortion. Difficulties in obtaining seeds from interspecific hybridization between Hydrangea macrophylla and H. arborescens had severely restricted the process of breeding new hydrangea varieties. To clarify the cause of reproductive barriers, an interspecific hybridization was made between H. macrophylla 'Endless Summer' (female parent) and H. arborescens 'Annabelle' (male parent). The results showed that both parents' floral organs developed normally, 'Annabelle' had high pollen viability (84.83% at 8 h after incubation), and the pollen tube could enter into the ovule of 'Endless Summer' at 72 h after pollination. Therefore, the pre-fertilization barrier was not the main reason for the failure of interspecific hybridization. However, observation of the embryo development by paraffin sections showed that the embryo was aborted at the heart-shaped stage. In addition, salicylic acid (SA) content was significantly higher (fourfold, P < 0.01) at 21 days after pollination (DAP) as compared to that of 17 DAP, which means SA may be closely correlated with embryo development. A total of 957 metabolites were detected, among which 78 were significantly different. During the embryo abortion, phenylpropanoids and polyketides were significantly down-regulated, while organic oxygen compounds were significantly up-regulated. Further analysis indicated that the metabolic pathway was enriched in the shikimic acid biosynthesis pathway, which suggests that more SA was synthesized. Taken together, it can be reasonably speculated that SA plays a key role leading to embryo abortion underlying the interspecific hybridization between Hydrangea macrophylla and H. arborescens. The result is helpful to direct the breeding of hydrangea through distant hybridization.

RESUMO

INTRODUCTION: The 2022 Massachusetts Shield Law protects telemedicine providers who care for abortion seekers in other states from criminal, civil, and licensure penalties. In this article we explore the characteristics of patients of The Massachusetts Medication Abortion Access Project (The MAP). METHODS: The MAP is an asynchronous telemedicine service that offers mifepristone/misoprostol to abortion seekers in all 50 states who are at or under 11 weeks pregnancy gestation on initial intake. The MAP charges USD250 using a pay-what-you-can model. We analyzed medical questionnaires and payments submitted by patients who received care from The MAP during its first 6 months of operations using descriptive statistics and for content and themes. RESULTS: From October 1, 2023-March 31, 2024, 1994 patients accessed care through The MAP. Almost all (n = 1973, 99%) identified as women/girls and about half (n = 984, 49%) were aged 20-29. The MAP cared for patients in 45 states; 84% (n = 1672) of these patients received pills in abortion ban or restricted southern states. Patients paid USD134.50 on average; 29% (n = 577) paid USD25 or less. Nearly two-thirds (n = 1293, 65%) received subsidized care; financial hardship featured prominently in patient comments. DISCUSSION: Considerable demand exists for medication abortion care from Shield Law providers. The MAP demonstrates that providers can trust women and other pregnancy capable people to decide for themselves whether to obtain medication abortion pills by mail and to pay what they can afford without being required to justify their need. Identifying ways to support Shield Law provision and further subsidize abortion care are needed.

RESUMO

In December 2020, Argentina approved a new abortion law following decades of feminist and social advocacy. This paper presents qualitative findings from interviews and focus group discussions with people in local communities focusing on how individuals of reproductive age access and communicate sexual and reproductive health information, particularly regarding abortion. Sixteen in-depth interviews were conducted with key informants working in the field of SRHR and four focus group discussions took place with cisgender women and girls, transmasculine people and non-binary people of reproductive age. We found that information exchange and communication about sexual and reproductive health issues, particularly abortion, took place mainly through informal social networks engaging with activists and feminist grass-root organisations. These informal social networks were built on trust as a collective affect that enabled open communication about abortion. Information sharing through word of mouth, in person and via digital means using different social media platforms, is an important means of information sharing and communication in Argentina. Monitoring the implementation of abortion policies in this country should include investigating the impact of people accessing abortion through informal social networks in terms of abortion pathways and intersections with the formal health system.

RESUMO

Objectives: It was aimed to evaluate the relationship of Dehydroepiandrosterone-sulphate(DHEAS) level with pregnancy, fertility, abortion, ovarian reserve and endothelial functions. Patients and Method: Ninety-six fertile women aged 20-35 years whose DHEAS levels were measured and 28 women aged 40-55 years with oligomenorrhea-amenorrhea were included in the study.The DHEAS values of the patients,which were measured at least 12 months apart,were recorded. Results: The first measured mean DHEAS level was 208.34±119.7ug/dL and the last measured mean DHEAS level was 187.5±101.7ug/dL. Among 28 patients with oligomenorrhea-amenorrhea, the levels of DHEAS increased in 10 patients and decreased in 18 patients. Although the annual decrease in DHEAS levels was greater in those who had pregnancy than in those who had not given birth, the difference was not statistically significant (p=0.085). Although the initial DHEAS level in 5 patients who had an abortion was higher than in those who did not have an abortion, the difference was not statistically significant (p=0.427). The increase in systolic blood pressure was statistically significant in patients with decreased DHEAS levels (p=0.03). While the mean DHEAS level was 85.3±47.3ug/dL in menopausal patients, the DHEAS level was 82.1±49.2ug/dL in non-menopausal patients (p=0.435). Conclusion: The age at which the DHEAS level reaches its peak level shows individual differences. While pregnancy slows down the decrease in DHEAS levels,abortion accelerates the decrease in DHEAS levels. A decrease in serum DHEAS levels can increase systolic blood pressure.

RESUMO

BACKGROUND: Prostaglandins (PGs) have emerged as key drugs in second trimester medical abortion (STMA) and are currently a cornerstone in obstetric practice. Nevertheless, the application of PGs, integral to labor and abortion procedures, is not risk-free, and has been associated with several complications, particularly maternal fever and uterine rupture (UR). OBJECTIVES: The main outcome of the present systematic review was to assess the safety of PGs use in STMA, particularly in scarred uterus (SC). SEARCH STRATEGY: The review adhered to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline. We performed a comprehensive systematic review by searching multiple databases, including MEDLINE, EMBASE, Global Health, The Cochrane Library, Health Technology Assessment Database, and the research registers of Web of Science during the years 1990-2022. SELECTION CRITERIA: Only articles regarding cases of UR occurred after the use of PGs for STMA were included in the article. We excluded papers regarding UR during first trimester abortion induction of labor or pregnancy or unrelated to PGs use for STMA. Risk of bias was assessed employing a modified version of the "Newcastle-Ottawa Scale" (NOS). DATA COLLECTION AND ANALYSIS: A total of 178 studies were initially identified as potentially meeting the criteria for inclusion in the review. After full text evaluation, 110 other articles were excluded and 67 studies that suited the inclusion criteria were included. A total of 19 of the included studies were judged to have a high risk of bias. Given the heterogeneous nature of the findings, we opted for a narrative synthesis of the results. MAIN RESULTS AND CONCLUSIONS: PGs appear to be an effective pharmacologic tool for STMA; however, their use is not entirely risk-free. STMA requires well-equipped obstetric centers with skilled clinicians and surgeons prepared for emergencies. Ultrasonographic scans should be routinely performed during STMA management, since a UR can also be silent during the induction of labor. Intrapartum transabdominal, transperineal, and transvaginal ultrasound may have the diagnostic potential to early recognize this obstetric emergency, to facilitate rapid medical and surgical treatment, improving the outcome.

RESUMO

Introduction: Failure to adequate decidualization leads to adverse pregnancy outcomes including pregnancy loss. Although there are plenty of reports underscoring immune dysfunction as the main cause of abortion in CBA/J females mated with DBA/2 males (CBA/J × DBA/2), little is known about the potential role of impaired endometrial decidualization. Methods: Endometrial stromal cells (ESCs) from CBA/J mice were in-vitro decidualized, and the proteome profile of the secretome was investigated by membrane-based array. CBA/J mice were perfused In-utero with either decidualized ESCs (C×D/D), undecidualized ESCs (C×D/ND), or PBS (C×D/P) 12 days before mating with DBA/2 males. Control mice were not manipulated and were mated with male DBA/2 (C×D) or Balb/c (C×B) mice. On day 13.5 of pregnancy, reproductive parameters were measured. In-vivo tracking of EdU-labeled ESCs was performed using fluorescence microscopy. The frequency of regulatory T cells (Tregs) in paraaortic/renal and inguinal lymph nodes was measured by flow cytometry. The proliferation of pregnant CBA/J splenocytes in response to stimulation with DBA/2 splenocytes was assessed by 5,6-carboxyfluorescein diacetate succinimidyl ester (CFSE) flow cytometry. Results: In C×D/D mice, the resorption rate was reduced to match that seen in the C×B group. Intrauterine perfused ESCs appeared in uterine stroma after 2 days, which remained there for at least 12 days. There was no difference in the number of implantation sites and embryo weight across all groups. The frequency of Tregs in the inguinal lymph nodes was similar across all groups, but it increased in the paraaortic/renal lymph nodes of C×D/D mice to the level found in C×B mice. No significant changes were observed in the proliferation of splenocytes from pregnant C×D/D compared to those of the C×D group in response to stimulation with DBA/2 splenocytes. Decidualization of ESCs was associated with a profound alteration in ESC secretome exemplified by alteration in proteins involved in extracellular matrix (ECM) remodeling, response to inflammation, senescence, and immune cell trafficking. Discussion: Our results showed that the deficiency of Tregs is not the primary driver of abortion in the CBA/J × DBA/2 model and provided evidence that impaired endometrial decidualization probably triggers endometrial immune dysfunction and abortion in this model.

RESUMO

Termination of pregnancy due to a fetal anomaly is a challenging and mentally stressful experience, associated with trauma-related stress, depression and symptoms of complicated grief. It differs from other types of pregnancy loss because of the role of active decision-making. Expectant parents depend on caring and experienced staff to guide them during a time full of ambiguity and contrasting emotions. This study examines how expectant parents experience the process of birth with termination of pregnancy due to fetal anomaly at a specialised unit for prenatal loss. Data was generated from semi-structured interviews with 11 women and 9 male partners, one to five months after termination of pregnancy. Three themes were identified 1) Suspended time/space bubble; the unit for prenatal loss was described as a time-space bubble, that promoted a sense of meaning, a feeling of togetherness and an awareness of parallel worlds, 2) The midwife matters; participants emphasised midwives' 'invisible', chronological and individualised practice, making it possible to be present and in the process, and 3) Meeting and spending time with the fetus/baby; participants' responses and relation to the fetus were very different, with most of them embracing the fetus as a baby, grateful for the opportunity to have time together. The findings from this study suggest a need for specialised midwives dedicated to prenatal loss, in units designed as private and protected spaces to accommodate the requirements of parents undergoing termination of pregnancy due to fetal anomaly.

RESUMO

BACKGROUND: In many countries, persons seeking medical abortion with mifepristone followed by misoprostol can self-administer the second drug, misoprostol, at home, but self-administration of the first drug, mifepristone, is not allowed to the same extent. OBJECTIVES: This systematic review aims to evaluate whether the efficacy, safety and women's satisfaction with abortion treatment are affected when mifepristone is self-administered at home instead of in a clinic. SEARCH STRATEGY: A literature search covered CINAHL, Cochrane Library, Embase, Ovid MEDLINE and APA PsycInfo in October 2022. SELECTION CRITERIA: Eligible studies focused on persons undergoing medical abortion comparing home and in-clinic mifepristone intake. Outcomes included abortion effectiveness, compliance, acceptability, and practical consequences for women. DATA COLLECTION AND ANALYSIS: Two reviewers independently assessed eligibility and risk of bias. Meta-analysis included similar studies while those differing in design were synthesised without meta-analysis. RESULTS: Six studies (54 233 women) of medical abortions up to 10 weeks were included. One randomised controlled trial and one retrospective register study had moderate risk of bias, and four non-randomised clinical trials where women could choose the place for intake of mifepristone had serious risk of bias. There was no difference in abortion effectiveness (high confidence) or compliance (moderate confidence) between mifepristone administered at home or in-clinic. No differences in complications were detected between groups and most women who chose home administration of mifepristone expressed a preference for this approach. CONCLUSIONS: Our systematic review demonstrates that the effectiveness of medical abortion is comparable regardless of mifepristone administration and intake, at home or in the clinic.

RESUMO

BACKGROUND: The United Nations' Sustainable Development Goals identify universal access to sexual and reproductive health services as a global priority. Yet barriers to abortion access remain, including legal restrictions, cost, stigma, and limited services and information. The aim was to identify barriers to and facilitators of abortion care access experienced in Australia. METHODS: This qualitative phenomenological study examined abortion access in Australia, where abortion is decriminalised, from March 2020 to December 2022. We used social media and flyers in clinics to recruit adults who had sought abortion care, then interviewed them in-depth. We mapped participant experiences to five dimensions of access identified by Levesque et al.'s patient-centred access to healthcare framework: approachability, acceptability, availability and accommodation, affordability, and appropriateness. RESULTS: The 24 participants lived across Australia and sought abortion during the COVID-19 pandemic. Approachability: Before seeking abortion, most did not know where to access information about the service and where to obtain it. Acceptability: Many were uncomfortable disclosing their abortion to family or friends; they reported that healthcare providers demonstrated varying levels of support. Availability and accommodation: Regional participants travelled far and faced long wait-times, exacerbated by pandemic restrictions. Affordability: Participants described financial stress paying for the service, travel, and related expenses. Appropriateness: Most participants expected judgemental care. Experiences varied widely: many participants experienced unempathetic, rushed, or judgemental interactions with healthcare staff, and many also reported at least one non-judgmental and supportive interaction on the same pathway to care. DISCUSSION: Abortion seekers experienced varying obstacles when seeking care. The findings illustrate the need for population- and system-level initiatives such as: providing accurate information about and normalising abortion; implementing system-level strategies to reduce wait times, travel, and costs, especially for rural populations; and developing regulatory and quality improvement initiatives to increase the workforce and its readiness to provide high-quality, non-judgemental abortion care. Challenges seeking care during pandemic restrictions illustrate the importance of social support during care and choice between abortion modalities and service types. Consumer voices can help understand the diverse pathways to abortion care and inform solutions to overcome the multidimensional barriers to access.

RESUMO

The emergence of FemTech technologies promises to revolutionize women's health and reproductive rights but conceals an insidious trap of surveillance and control in the hands of private and state actors. This article examines the extent to which FemTech technologies, under the guise of empowerment, enable private actors to play a leading role in managing reproductive rights, replacing largely inactive States in this crucial function. The analysis shows how private FemTech companies are becoming critical players in implementing and defending these rights, often in response to the inaction or inadequacies of States. The article approaches the FemTech phenomenon from several angles, including the promises of empowerment, concerns about surveillance and control, and the ambivalent roles of private actors as implementers and defenders of reproductive rights. This structure makes it possible to offer a critical analysis of the legal, societal, and ethical implications of FemTech, highlighting the tensions between the promises of empowerment and the risks of surveillance and control.

RESUMO

Objective: 26% of all pregnancies end in miscarriage, and up to 10% of clinically diagnosed pregnancies, and recurrent pregnancy loss is 5% among couples of childbearing ages. Although there are several known causes of pregnancy loss in the first half, including recurrent pregnancy loss, including parental chromosomal abnormalities, uterine malformations, endocrinological disorders, and immunological abnormalities, about half of the cases of pregnancy loss in its first half remain unexplained. Methods: The review includes observational controlled studies (case-control or cohort, longitudinal studies, reviews, meta-analyses), which include the study of biochemical factors for predicting pregnancy losses in the first half, in singlet pregnancy. The Newcastle-Ottawa Scale (NOS) was used to assess the research quality. Results: Finally, 27 studies were included in the review, which has 134904 examined patients. The results of the review include estimates of ß-human chorionic gonadotropin, progesterone, pregnancy-associated protein - A, angiogenic vascular factors, estradiol, α-fetoprotein, homocysteine and CA-125 as a predictors or markers of the first half pregnancy losses. Conclusion: It may be concluded that to date, research data indicate the unavailability of any reliable biochemical marker for predicting pregnancy losses in its first half and require either a combination of them or comparison with clinical evidence. A fairly new model shall be considered for the assessment of α-fetoprotein in vaginal blood, which may have great prospects in predicting spontaneous miscarriages.

RESUMO

The effects of chemical components of ambient fine particulate matter (PM2.5) on human early maternal-fetal interface are unknown. We estimated the associations of PM2.5 and component exposures with placental villi 8-hydroxy-2'-deoxyguanosine (8-OHdG) in 142 normal early pregnancy (NEP) and 142 early pregnancy loss (EPL) from December 2017 to December 2022. We used datasets accessed from the Tracking Air Pollution in China platform to estimate maternal daily PM2.5 and component exposures. Effect of average PM2.5 and component exposures during the post-conception period (i.e., from ovulation to villi collection) on the concentration of villi 8-OHdG were analyzed using multivariable linear regression models. Distributed lag and cumulative effects of PM2.5 and component exposures during the periovulatory period and within ten days before villi collection on villi 8-OHdG were analyzed using distributed lag non-linear models combined with multivariable linear regression models. Per interquartile range increase in average PM2.5, black carbon (BC), and organic matter (OM) exposures during the post-conception period increased villi 8-OHdG in all subjects (ß = 34.48% [95% CI: 9.33%, 65.42%], ß = 35.73% [95% CI: 9.08%, 68.89%], and ß = 54.71% [95% CI: 21.56%, 96.91%], respectively), and in EPL (ß = 63.37% [95% CI: 16.00%, 130.10%], ß = 47.43% [95% CI: 4.30%, 108.39%], and ß = 72.32% [95% CI: 18.20%, 151.21%], respectively), but not in NEP. Specific weekly lag effects of PM2.5, BC, and OM exposures during the periovulatory period increased villi 8-OHdG in all subjects. Ten-day cumulative and lag effects of PM2.5, BC, and OM increased villi 8-OHdG in all subjects and EPL, but not in NEP; and the effects of OM were robust after adjusting for BC, ammonium, nitrate, or sulfate in two-pollutant models. In conclusion, placental oxidative DNA damage in early pregnancy was associated with maternal exposure to PM2.5, especially its chemical components BC and OM.

RESUMO

BACKGROUND: Recurrent spontaneous abortion (RSA) is defined as two or more consecutive spontaneous abortions before 20 weeks with the same spouse [1]. However, approximately 50% of RSA cases of unknown cause are classified as unexplained recurrent spontaneous abortion (URSA). Potential factors include decreased trophoblast cell migration and invasion, leading to impaired placental implantation and maintenance of the normal maternal-fetal interface. However, the mechanism of this pathogenesis remains unknown. In this study, we investigated the potential role and mechanism of KLF4 in regulating URSA by influencing the invasion and migration ability of trophoblast cells. METHODS: We firstly identified 817 differentially expressed genes by performing a difference analysis of the dataset GSE121950 [2] related to recurrent abortion, and intersected the top 10 genes obtained respectively by the three algorithms: DMNC, MNC, and EPC using Venn Diagram.To detect the expression levels of core genes, villi samples were obtained from normal pregnant women and patients with URSA. RT-qPCR analysis revealed a significant difference in KLF4 mRNA expression and KLF4 was then analyzed. Trophoblast cell lines HTR8 and JEG3 were used to investigate the effect of KLF4 on trophoblastic function. Wound healing and transwell assays was performed to detect the invasion and migration of trophoblast cells. The expression of epithelial-mesenchymal transition(EMT) molecules were detected by RT-qPCR and western blot. Promoter detection and epigenetic modification were detected by chromatin immunoprecipitation (ChIP) assay. Molecular nuclear localization was detected by immunofluorescence and subcellular fractionation. Miscarried mice model was used to study the effects of KLF4 on URSA induced by reduced trophoblast invasion and migration. RESULTS: KLF4 is highly expressed in the villi of patients with URSA. KLF4 inhibits the expression level of H3R2ME2a in trophoblast cells by regulating the transcriptional level and nuclear translocation of PRMT6, thereby inhibiting the possible regulatory mechanism of trophoblastic invasion and providing a potential treatment strategy for URSA in vivo. CONCLUSIONS: The KLF4/PRMT6/H3R2ME2a axis regulates mechanisms associated with unexplained recurrent spontaneous abortion by regulating trophoblast function.
