RESUMO
Background: Neuromyelitis optica spectrum disorder (NMOSD) primarily affects women of childbearing age. Objectives: Studying the potential relationship between NMOSD and pregnancy characteristics and outcomes. Subjects and methods: This is a retrospective cohort study that was conducted on 66 married female patients diagnosed with NMOSD. All patients underwent a thorough review of their demographic and clinical history through their medical records and personal interviews. Additionally, a complete neurological examination was performed, along with the expanded disability status scale (EDSS) and a pregnancy registry questionnaire. Results: After comparing married patients before and after disease onset, there was a significant increase in the number of abortions and the percentage of cesarean sections, as well as a decrease in the percentage of breastfeeding after disease onset. The p values were .02, <.001, and <.001, respectively, with odds ratios of 2.03, 5.13, and 6.17. Additionally, there was a rise in the occurrence of postpartum relapses, which accounted for 66% of all relapses after the disease onset. Most of these relapses (88.7%) occurred within the first 3 months postpartum. Conclusion: Presence of NMOSD increased the percentage of miscarriage, delivery by cesarean section, and decreased the chance of breastfeeding. In addition, pregnancy increases NMOSD relapse and subsequent disability.
RESUMO
Teratogenic plants can be found in pastures in different parts of the world and represent a threat to the reproduction of ruminants. In the northeast region of Brazil, several studies have indicated that Cenostigma pyramidale (Tul.) Gagnon & G.P.Lewis is one of the main poisonous plants that causes reproductive problems in sheep and goats. In this context, the present study reviewed spontaneous and experimental poisonings reports by C. pyramidale in sheep and goats, as well as analyzing the phytochemical evidence related to this species. The scientific documents were retrieved from different databases and, after applying the selection criteria, a total of 16 articles published between 2000 and 2024 were included in this review. Cenostigma pyramidale causes embryonic loss, abortion, and congenital malformations in pregnant sheep and goats in the Brazilian semi-arid region. The main malformations observed in newborn animals are arthrogryposis, scoliosis, micrognathia, multiple skull deformities, cleft palate, and brachygnathism. Many secondary metabolites have already been isolated from C. pyramidale, however, to date, no evidence has been found regarding the possible teratogenic compounds that occur in this plant. From this perspective, new phytochemical studies are necessary to help unravel the mechanisms of action of embryotoxic agents from C. pyramidale.

Unsafe abortions contribute significantly to maternal mortality and morbidity in Ghana. To reduce this, in 1982 abortion laws in Ghana underwent reform to broaden the conditions under which abortion is accessed. Although, evidence in other contexts highlights the contribution of violence to women's experience of unwanted pregnancy and abortion, such evidence is limited within the Ghanaian abortion literature. This study aims to fill that gap. Informed by phenomenology, interviews were conducted with 10 women who had experienced various forms of violence leading to unwanted pregnancy and unsafe abortions. Participants were recruited between June 2017 and March 2018 in the Ashanti region of Ghana where they sought hospital care for unsafe abortion related complications. Participants mentioned intimate partners as the main perpetrators of violence. Financial challenges were also identified as important in increasing women's vulnerability to violence. Verbal abuse from health workers contributed to denying women access to safe abortion. This paper advances dialogue about the ways in which women's experience of violence from intimate/non-intimate partners and healthcare workers impacts their overall abortion experience. It advocates the empowerment of women to enable them to leave violent relationships, and the retraining of health workers to enable them to adopt respectful and empathetic care practices.
RESUMO
The reproductive features of equine leptospirosis are often neglected. Equine genital leptospirosis is characterized as a silent chronic syndrome, and besides abortions, leads to placental abnormalities, stillbirths, and birth of weak foals. This study aimed to study the occurrence of placental abnormalities associated with Leptospira interrogans infection in naturally infected mares under field conditions. The studied herd had a high occurrence of placentitis and abortions. Ten pregnant mares, eight with placental abnormalities on ultrasonography and were selected. Serum and cervicovaginal mucus (CVM) samples were collected for serology and PCR, respectively. Positive samples in lipL32-PCR were submitted to the sequencing of the secY gene. In lipL32-PCR of CVM, five out of 10 (50%) mares were positive and all were characterized as Leptospira interrogans. Our results highlight the presence of placental abnormalities in the reproductive subclinical leptospirosis syndrome. We encourage field veterinarians to include leptospirosis testing in their reproductive management.

A basic hypothesis is that cultural evolutionary processes sustain differences between groups, these differences have evolutionary relevance and they would not otherwise occur in a system without cultural transmission. The empirical challenge is that groups vary for many reasons, and isolating the causal effects of culture often requires appropriate data and a quasi-experimental approach to analysis. We address this challenge with historical data from the final Soviet census of 1989, and our analysis is an example of the epidemiological approach to identifying cultural variation. We find that the fertility decisions of Armenian, Georgian and Azeri parents living in Soviet-era Russia were significantly more son-biased than those of other ethnic groups in Russia. This bias for sons took the form of differential stopping rules; families with sons stopped having children sooner than families without sons. This finding suggests that the increase in sex ratios at birth in the Caucasus, which began in the 1990s, reflects a cultural preference for sons that predates the end of the Soviet Union. This result also supports one of the key hypotheses of gene-culture coevolution, namely that cultural evolutionary processes can support group-level differences in selection pressures that would not otherwise occur in a system without culture.
RESUMO
In humans, aneuploidy is incompatible with the birth of healthy children and mainly leads to the death of embryos in the early stages of development in the first trimester of pregnancy. Trisomy 16 is the most common aneuploidy among spontaneous abortions of the first trimester of pregnancy. However, the mechanisms leading to the death of embryos with trisomy 16 remain insufficiently investigated. One of these potential mechanisms is abnormal placental development, including aberrant remodeling of spiral arteries. Spiral artery remodeling involves the migration of trophoblast cells into the maternal spiral arteries, replacing their endothelium and remodeling to ensure a stable embryonic nutrition and oxygen supply. This is a complex process which depends on many factors from both the embryo and the mother. We analyzed the methylation level of seven genes (ADORA2B, NPR3, PRDM1, PSG2, PHTLH, SV2C, and TICAM2) involved in placental development in the chorionic villi of spontaneous abortions with trisomy 16 (n = 14), compared with spontaneous abortions with a normal karyotype (n = 31) and the control group of induced abortions (n = 10). To obtain sequencing libraries, targeted amplification of individual gene regions using designed oligonucleotide primers for bisulfite-converted DNA was used. The analysis was carried out using targeted bisulfite massive parallel sequencing. In the group of spontaneous abortions with trisomy 16, the level of methylation of the PRDM1 and PSG2 genes was significantly increased compared to induced abortions (p = 0.0004 and p = 0.0015, respectively). In the group of spontaneous abortions, there was no increase in the level of methylation of the PRDM1 and PSG2 genes, but the level of methylation of the ADORA2B gene was significantly increased compared to the induced abortions (p = 0.032). The results obtained indicate the potential mechanisms of the pathogenetic effect of trisomy 16 on the placental development with the participation of the studied genes.
RESUMO
Listeria monocytogenes, a gram-positive bacillus and an intracellular pathogen, is an uncommon cause of illness in the general population. During pregnancy, a perinatal infection can lead to serious complications such as abortion, stillbirth, neonatal sepsis, and meningitis. We present two cases of neonatal meningitis caused by Christie, Atkins, Munch-Peterson (CAMP)-negative Listeria monocytogenes. In the first case, a seven-day-old female term neonate delivered vaginally, presented with high-grade fever and refusal to feed. In view of the suspected late-onset sepsis, a septic workup, including cerebrospinal fluid analysis, was conducted. CSF culture reports obtained showed a growth consistent with Listeria monocytogenes, which was CAMP test negative and susceptible to the penicillin group of drugs, cotrimoxazole, erythromycin, and meropenem. The isolate was identified using matrix-assisted laser desorption ionization-time of flight mass spectrometry (MALDI-TOF MS) and confirmed by 16S rRNA sequencing. The blood culture was sterile. At 48 hours of admission, the neonate clinically deteriorated with fluctuation in oxygen saturation below 95% at room air. Thus, she was electively intubated and connected to the mechanical ventilator with appropriate settings. The antibiotics were upgraded to meropenem from the empirical antibiotic therapy. The neonate showed clinical improvement within the next 24 hours of initiating antibiotics according to culture susceptibility and was gradually weaned from the mechanical ventilator to continuous positive airway pressure (CPAP). After 24 hours, she was able to maintain normal saturation at room air. In the second case, an 11-day-old low birth weight neonate, small for gestational age, was presented to the NICU with complaints of loose stools, fever, and refusal to feed for the past two days. In view of the suspected sepsis, relevant investigations were carried out while initiating empirical antibiotics IV piperacillin-tazobactam and IV amikacin for the neonate. Meanwhile, there was a dip in oxygen saturation noted on room air for the neonate and he/she was mechanically ventilated. The CSF culture grew Listeria monocytogenes,which was identified using MALDI-TOF MS and confirmed by 16S rRNA sequencing. The isolate tested negative for the CAMP test and was susceptible to ampicillin, penicillin, cotrimoxazole, erythromycin, and meropenem. The blood culture was sterile. The antibiotics were upgraded to meropenem from the empirical antibiotic therapy, the patient's condition improved, and the baby was eventually discharged.
RESUMO
PROBLEM: A comprehensive analysis was conducted to explore the scientific output on immune-related recurrent pregnancy loss (RPL) and its key aspects. Despite the lack of clear explanations for most RPL cases, immune factors were found to play a significant role. METHOD OF STUDY: The study utilized a bibliometric approach, searching the Web of Science Core Collection database for relevant literature published between 2004 and 2023. RESULTS: The collected dataset consisted of 2228 articles and reviews, revealing a consistent increase in publications and citations over the past two decades. The analysis identified the United States and China as the most productive countries in terms of RPL research. Among the institutions, Fudan University in China emerged as the top contributor, followed by Shanghai Jiaotong University. Kwak-kim J was the most prolific author, while Christiansen Ob had the highest number of co-citations. The top 25 co-cited references on diagnosis, treatment, and mechanisms formed the foundation of knowledge in this field. By examining keyword co-occurrence and co-citations, the study found that antiphospholipid syndrome and natural killer cells were the primary areas of focus in immune-related RPL research. Additionally, three emerging hotspots were identified: chronic endometritis, inflammation, and decidual macrophages. These aspects demonstrated increasing interest and research activity within the field of immune-related RPL. CONCLUSIONS: Overall, this comprehensive bibliometric analysis provided valuable insights into the patterns, frontiers, and focal points of global scientific output related to immune-related RPL.

Abortion policy is conventionally viewed as a political matter with religious overtones. This article offers a different view. From the perspective of evolutionary biology, abortion at a young age can represent prioritization of long-term development over immediate reproduction, a pattern established in other animal species as resulting from stable ecologies with low mortality risk. We examine whether laws and moral beliefs about abortions are linked to local mortality rates. Data from 50 U.S. states, 202 world societies, 2,596 adult individuals in 363 U.S. counties, and 147,260 respondents across the globe suggest that lower levels of mortality risk are associated with more permissive laws and attitudes toward abortion. Those associations were observed when we controlled for religiosity, political ideology, wealth, education, and industrialization. Integrating evolutionary and cultural perspectives offers an explanation as to why moral beliefs and legal norms about reproduction may be sensitive to levels of ecological adversity.

The aim of this study was to evaluate the immunological activities of human decidual mesenchymal stem cells (MSCs) on proliferation, apoptosis and percentage of regulatory T cells (Treg) in abortions and to investigate whether these activities differ in spontaneous abortions (SA) and recurrent abortions (RA). This prospective cohort study included women who had a first-trimester abortion between 2019 and 2022. Women with uterine anomaly, endocrinological disease, known autoimmune or thrombophilic disease, and fetal chromosomal abnormality in abortion material were excluded. Decidual MSCs isolated from abortion materials were classified as spontaneous abortion-MSCs (SA-MSCs) and recurrent abortion-MSCs (RA-MSCs). Peripheral blood mononuclear cells were isolated from venous blood and co-cultured with SA-MSCs and RA-MSCs. The effects of MSCs on proliferation and apoptosis of lymphocytes, and Tregs levels were compared between SA-MSCs and RA-MSCs groups. Thirty cases (15 SA-MSCs and 15 RA-MSCs) were included in the study. The presence of MSC in co-cultures increased percentage of Treg cells while reducing proliferation and apoptosis compared to those without MSCs (p < 0.0001, p < 0.0001 and p < 0.0001). The increase in percentage of Treg cells and the reduction in apoptosis were significantly lower in the RA-MSCs group compared to the SA-MSCs group (p < 0.0001 and p < 0.001, respectively). Although the proliferation reducing effect of the presence of MSCs was lower in the RA-MSCs group compared to the SA-MSCs group, the difference was not significant (p = 0.07). MSCs contribute to maternal immunotolerance to semi-allogeneic fetus by suppressing proliferation and apoptosis, and increasing percentage of Treg cells. However, the immunoregulatory effects of MSCs are lower in RA compared to SA.

Bans on sex-selective abortions are typically implemented to make sex ratios more equitable, but they may have adverse effects on surviving children. We examine the impacts of a ban on prenatal sex selection in India on postnatal health outcomes. We first show that the ban increased the share of female children born to mothers, especially among firstborn female families. Strikingly, we also find that the ban led to a worsening of mortality outcomes for both girls and boys in firstborn female families. In terms of mechanisms, we find that fertility increases in firstborn female families after the ban, pointing to the following channel: firstborn female families are disproportionately affected by the ban and are more likely to use the son-biased fertility stopping rule to achieve a desired number of sons. Children in firstborn female families likely face greater competition for parental resources, which may worsen their health.

PURPOSE: The purpose of this study is to investigate the function of miR-150-5p in URSA. METHOD: Twenty-six chorionic villous tissues were collected to examine the expression of miR-150-5p and VEGFA by using quantitative polymerase chain reaction (qPCR) and western blot assay, respectively. Transwell assay was conducted to assess the migration and invasion ability of trophoblast cells. The dual-luciferase reporter assay was applied to determine the relationship between miR-150-5p and VEGFA in vitro. Relevant signaling pathway protein expression level was measured via western blot assay. Signaling transduction inhibitor LY294002 was used to block PI3K/AKT/mTOR signaling pathway. Finally, in vivo the effect of miR-150-5p on embryonic absorption rate was evaluated in mice. RESULTS: Clinical samples revealed that miR-150-5p expression was significantly elevated in the villous tissues and serum of URSA patients. Moreover, the overexpressing of miR-150-5p could inhibit both HTR-8/SVneo cell and JAR cell migration, invasion, and restrained PI3K/AKT/mTOR signaling pathway by targeting VEGFA in vitro. This inhibitory effect of miR-150-5p could be reversed by overexpressing the gene of vascular epithelial growth factor A (VEGFA). In contrary, inhibition of miR-150-5p significantly enhanced migration, invasion ability of both HTR-8/SVneo and JAR cells, and also could stimulate PI3K/AKT/mTOR signaling pathway. This promoting effect of miR-150-5p could be ameliorated by LY294002 (PI3K inhibitor). Finally, after miR-150-5p overexpression in vivo, the embryo resorption rate in pregnant mice was increased significantly. CONCLUSIONS: Overall, these findings imply that miR-150-5p is among the key factors that regulate the pathogenesis of URSA.

BACKGROUND: In Sri Lanka, the Emergency Contraceptive Pill (ECP) is categorized as a Schedule 2A medication, allowing it to be purchased over-the-counter without a prescription, but exclusively from licensed pharmacists. It is estimated that around 3 million ECPs are consumed by Sri Lankan women each year. This study aims to assess the knowledge and practices of Female Factory Workers (FFWs) on ECP and to unearth the association with unintended pregnancy and unsafe abortion. METHODS: After receiving written informed consent, a structured interview schedule was administered among 585 FFWs attached to eight factories in a selected Export Processing Zone (EPZ). Data analysis was performed using SPSS software. RESULTS: Only 26 % of FFWs were aware of the effective time period to take an ECP to prevent a pregnancy. Most (67 %) had the impression that a valid prescription is required to purchase ECP from the pharmacies. Around one-tenth of the FFWs (11.3 %, n = 66) had used ECP during their lifetime. Among the 65 respondents who reported having experienced unintended pregnancies, only 26.2 % (n = 17) had utilized ECPs. In contrast, among the 22 respondents who disclosed a history of abortion, only two women had ever employed ECPs. CONCLUSION: The study highlights the low knowledge and use of ECP among FFWs in Sri Lanka, contributing to unintended pregnancy and unsafe abortion. Results call for targeted interventions to improve knowledge and access to ECP, helping to reduce unintended pregnancy and improve reproductive health outcomes.

BACKGROUND: Few studies have explored the association between the number of SAs and bipolar disorder and major depression (BDMD). This study aims to investigate the association between SA and BDMD, and the possible dose-response relationship between them. METHODS: We conducted a cross-sectional study of 13,200 female UK Biobank participants. Participants were classified into BDMD and no-BDMD groups based on their BDMD status. The number of SAs was grouped into non-SA, occasional SA (OSA), and recurrent SA (RSA). Baseline characteristics of the three groups were balanced using inverse probability treatment weighting (IPTW) based on propensity scores. The three-knots restricted cubic spline regression model was utilized to assess the dose-response relationship between the number of SAs and BDMD. RESULTS: The IPTW-adjusted multivariate logistic regression revealed that SA was an independent risk factor for BDMD, with adjusted OR of 1.12 (95 % CI: 1.07-1.19) and 1.32 (95 % CI: 1.25-1.40) in the OSA and RSA groups, respectively. The strength of this association amplified as the number of SAs (P for trend <0.001). There was a nonlinear relationship between the number of SAs and the risk of BDMD, with an approximately inverted L-shaped curve. LIMITATIONS: The information of the SA and BDMD status relied on self-reported by volunteers, and the study sample was mostly of European descent. CONCLUSIONS: Women who reported experiencing multiple SAs are more likely to have BDMD. Therefore, it is imperative to provide psychological care and interventions for women in the postpartum period.

INTRODUCTION: Thrombophilic genetic polymorphisms of the platelet glycoproteins Ia (GpIa) and IIIa (GpIIIa) have been associated with an increased risk of recurrent miscarriages. The aim of this study was to investigate the association of genetic polymorphisms GpIa-C807T and GpIIIa-T1565C-PlA1/PlA2 with platelet function in women with unexplained spontaneous recurrent miscarriages. METHODS: This cross-sectional study comprised 196 unrelated nulliparous Greek women with a history of unexplained recurrent miscarriages. Patients were genotyped for the presence of the GpIa-C807T (rs1126643) and GpIIIa-T1565C-PlA1/PlA2 (rs5918) genetic polymorphisms by pyrosequencing, and the collagen/epinephrine closure time (COL/EPI CT) of the subjects was assessed using the platelet function analyzer (PFA)-100. RESULTS: In the total population of women with recurrent miscarriages, the COL/EPI CT ranged from 70 to 160 seconds (median: 122 seconds, interquartile range (IQR): 102.3-138 seconds). In comparison with the double homozygotes CC/PlA1PlA1 that had the most prolonged CT (mean: 131.9 ± 17.5 seconds), the COL/EPI CT was statistically significantly shorter for the GpIa-807T single carriers (mean: 120.3 ± 20.9 seconds) (p=0.011) (absolute difference: 11.6 seconds, 95% confidence interval (CI): 21.2 to -2.0 seconds; relative difference: -9%, 95% CI: -16% to -2%), and the GpIIIa-PlA2 single carriers also displayed a trend for shorter COL/EPI CT (mean: 121.3 ± 23.7 seconds) (p=0.141) (absolute difference: -10.6 seconds, relative difference: -8%), whereas the combined carriers of the GpIa-807T and the GpIIIa-PlA2 alleles exhibited the shortest COL/EPI CT (mean: 104.1 ± 19.7 seconds) (absolute difference: -27.7 seconds, 95% CI: -39.1 to -16.3 seconds; relative difference: -21%, 95% CI: -30% to -12%) (p<0.001). In comparing genotype frequencies in the lower half with those in the upper half of the COL/EPI CT range, the GpIa-807T and the GpIIIa-PlA2 single carriers were associated with higher odds of COL/EPI CT < 122 seconds (odds ratio (OR)=3.4, 95% CI: 1.5 to 7.5, p=0.002, and OR=2.6, 95% CI: 1.0 to 7.2, p=0.053, respectively). The association was strongest for the combined carriers with OR of 15.0 (95% CI: 5.2 to 43.2, p<0.001) for COL/EPI CT below the median and OR of 35.5 (95% CI: 4.4 to 284.5, p<0.001) for COL/EPI CT < 100 seconds. CONCLUSION: The GpIa-C807T and GpIIIa-PlA1/PlA2 polymorphisms and more pronouncedly the combined carriers of the risk variants are associated with enhanced platelet reactivity expressed via shorter COL/EPI CT. These findings provide further evidence for the role of platelet-associated genetic thrombophilia in the pathogenesis of recurrent miscarriages and promote the analysis of platelet function as a diagnostic tool in the evaluation of this disorder.
RESUMO
Background A case series report based on the Turnaway Study has previously concluded that 99% of women with a history of abortion will continue to affirm satisfaction with their decisions to abort. Those findings have been called into question due to a low participation rate (31%) and reliance on a single yes/no assessment of decision satisfaction. Aim To utilize more sensitive scales in assessing decision satisfaction and the associated mental health outcomes women attribute to their abortions. Method A retrospective survey was completed by 1,000 females, aged 41-45, living in the United States. The survey instrument included 11 visual analog scales for respondents to rate their personal preferences and outcomes they attributed to their abortion decisions. A categorical question allowed women to identify if their abortions were wanted and consistent with their own values and preferences, inconsistent with their values and preferences, unwanted, or coerced. Linear regression models were tested to identify which of three decision scales best predicted positive or negative emotions, effects on mental health, emotional attachment, personal preferences, moral conflict, and other factors relevant to an assessment of satisfaction with a decision to abort. Results Of 226 women reporting a history of abortion, 33% identified it as wanted, 43% as accepted but inconsistent with their values and preferences, and 24% as unwanted or coerced. Only wanted abortions were associated with positive emotions or mental health gains. All other groups attributed more negative emotions and mental health outcomes to their abortions. Sixty percent reported they would have preferred to give birth if they had received more support from others or had more financial security. Conclusions Perceived pressure to abort is strongly associated with women attributing more negative mental health outcomes to their abortions. The one-third of women for whom abortion is wanted and consistent with their values and preferences are most likely over-represented in studies initiated at abortion clinics. More research is needed to understand better the experience of the two-thirds of women for whom abortion is unwanted, coerced, or otherwise inconsistent with their own values and preferences.
RESUMO
Intrauterine adhesions are a serious complication that occurs after intrauterine procedures, most often in connection with pregnancy. Manifestations such as amenorrhea, pelvic pain, and infertility for a woman, especially in reproductive age, are serious and together with intrauterine adhesions we call them Asherman's syndrome. Primary prevention after intrauterine procedures is important. Published studies show that the use of hyaluronic acid gel, especially after abortions, leads to the prevention of moderate and severe intrauterine adhesions and also increases the pregnancy rate.
