Reproductive and developmental safety evaluation of Thymelaea hirsuta (L.) leaves aqueous extract in Wistar albino rats.

ETHNOPHARMACOLOGICAL RELEVANCE: The popularity of herbal medicine is expanding globally due to the common belief that herbal products are natural and nontoxic. Thymelaea hirsuta leaves are traditionally used for the treatment of recurrent abortion in humans and animals. However, a lack of safety evaluation of the plant, particularly in pregnant women, raises serious concerns regarding its potential embryotoxic effects. AIM OF THE STUDY: Therefore, the present study investigated the safety of Thymelaea hirsuta leaves aqueous extract (THLE) during pregnancy and lactation following maternal rat treatment. MATERIALS AND METHODS: THLE phytochemical compounds were identified using high-performance liquid chromatography (HPLC). THLE was orally administered to pregnant rats and lactating dams at dosages of 0, 250, 500, and 1000 mg/kg/day. At the end of the study, dam s' and pups' body weights, serum biochemical and hematological indices, and histopathological changes were investigated. For the fetal observation and histopathological changes were also evaluated. RESULTS: Our findings revealed that THLE is rich in different phenolic and flavonoid compounds. However, biochemical and hormonal parameters such as ALT, AST, and prolactin were significantly increased in dams treated with a higher dosage of THLE when compared to the control dams (P ≤ 0.05). Additionally, external, visceral and skeletal examinations of fetuses revealed a marked increase of malformation rates in treated fetuses. CONCLUSIONS: The results revealed that higher oral dosing of THLE during pregnancy could affect embryonic development in rats, while lower doses are safe and can be used during pregnancy and lactation to attain its beneficial effects.

Rural women's voices revealing perceptions about decisions on where to give birth in Gabon: A qualitative study.

OBJECTIVE: This study aimed to clarify the perceptions of rural women about their decisions on where to give birth in Gabon. METHOD: This study used a qualitative descriptive design using semi-structured interviews. Study participants were women at least 20 years old and had given birth within the past 2 years. The study area was approximately 25-30 km from the capital of Gabon. Data collection was conducted between May and mid-July 2023. The interview guide was based on the Ottawa Decision Support Framework (ODSF) 2020 model. The data obtained were analyzed using content analysis for "perceptions in deciding the place of birth." RESULTS: A total of 18 women participated in the study. Six categories of reasons were identified for women's choice of birth location: (1) childbirth environment with physical safety; (2) childbirth environment with psychological safety; (3) physical accessibility; (4) affordable health facilities; (5) concerns about homebirth risks; and (6) unpleasant aspects of the hospital. Items (1)-(4) were the reasons for actively choosing the hospital as a birth location, whereas items (5) and (6) were the reasons for avoiding a place to give birth. CONCLUSIONS: Women positively perceived and chose facilities that offer physical and mental safety, geographic accessibility, and affordable costs. Conversely, an environment where the safety of the mother and the child is threatened and the lack of respectful maternity care by the medical staff served as deterrents to facility use.

Development of the Hiesho (sensitivity of hands or feet to cold) Care Practice Scale for pregnant women.

AIM: Evidence-based indicators are needed to increase the frequency of practicing care for hiesho, which can be a risk factor during childbirth. Such practice will lead to hiesho prevention. This study aimed to develop a Hiesho Care Practice Scale (HCPS) for pregnant women and examine its reliability and validity. METHODS: To develop a HCPS and examine its reliability and validity, we conducted a questionnaire-based survey among nurses who provide hiesho care for pregnant women in Japan. RESULTS: The analysis included 100 participants (recovery rate: 96%). Exploratory factor analysis produced four factors and 20 items. The model's fit indices obtained from the confirmatory factor analysis include goodness of fit of .80, adjusted goodness of fit of .75, comparative fit index of .88, and root mean squared error of approximation of .08. The correlation coefficients for the patient coaching skill evaluation scale for criterion-related validity test ranged from .23 to .51 (p < .01). Cronbach's α was .88, and intraclass correlation coefficient (ICC) was .81. CONCLUSIONS: The HCPS developed in this study consisted of four factors and 20 items, and its reliability and validity were verified. This scale enables the subjective and objective evaluation of hiesho care practice in the nursing profession. It may contribute to standardizing and developing improvement measures for hiesho care among pregnant women by nurses and midwives.

Associations of multiple metals exposure with immunoglobulin levels in pregnant women: Hangzhou Birth Cohort Study.

Metal may affect maternal immune function, but few epidemiological studies have reported the associations between multiple-metal exposure and maternal immunoglobulin (Ig) levels. Based on the Hangzhou Birth Cohort Study, 1059 participants were included, and eleven metals in whole blood samples and serum IgA, IgG, IgE and IgM levels were measured. Linear regression, quantile-based g-computation (QGC), and Bayesian kernel machine regression (BKMR) models were used to evaluate the associations. Compared with the first tertile of metal levels, arsenic (As) was negatively associated with IgE (ß = -0.25, 95% confidence interval (CI) = -0.48 to -0.02). Moreover, significant associations of manganese (Mn) with IgA, IgG and IgM were demonstrated (ß = 0.10, 95% CI = 0.04 to 0.18; ß = 0.07, 95% CI = 0.03 to 0.12; ß = 0.10, 95% CI = 0.03 to 0.18, respectively). Cadmium (Cd) were associated with higher levels of IgM. QGC models showed the positive association of the metal mixtures with IgA and IgG, with Mn playing a major role. Mn and Cd had positive contributions to IgM, while As had negative contributions to IgE. In the BKMR models, the latent continuous outcomes of IgA and IgG showed a significant increase when all the metals were at their 60th percentile or above compared to those at their 50th percentile. Therefore, exposure to metals was associated with maternal Igs, and mainly showed that Mn was associated with increased levels of IgA, IgG and IgM, and As was associated with low IgE levels.

Leveraging the Fetal and Infant Mortality Review (FIMR) Process to Advance Health Equity.

The fetal and infant mortality review (FIMR) process is a community-oriented strategy focused on improving the health services systems for pregnant persons, infants, and their families. FIMR helps communities to understand and change systems that contribute to racial disparities in birth outcomes. FIMR equally values the medical and social services delivery records and the personal narratives of families who have suffered a fetal or infant loss when creating the de-identified case summaries to be reviewed by teams. A two-tiered process, FIMR uses a multidisciplinary Case Review Team (CRT) as the information processor and the Community Action Team (CAT) as the action arm of the process. Pediatricians are vital to both teams, helping to bring about systems change to improve maternal and child health. This paper examines how the well-established FIMR team serving Indianapolis (Marion County, IN) worked to build the capacity of its CAT to address racial disparities in birth outcomes through 5 distinct steps: focus on the primary causes of local fetal or infant mortality, focus on neighborhoods with the highest stable fetal or infant mortality rates, designation of a CAT leader, creation of a culture of regular CAT meetings inclusive of a health-equity skill building curriculum, and inclusion of Grassroots Maternal and Child Health Leaders on the CAT. This paper demonstrates how the synergy between local organizations and community members can effectively address racial disparities in birth outcomes.

Fetal, Infant, and Child Death Review: A Public Health Approach to Reducing Mortality and Morbidity.

Fetal, infant, and child death reviews are a longstanding public health effort to understand the circumstances of individual deaths and use individual and aggregate findings to prevent future fatalities and improve overall child health. Child death review (CDR) began in the United States in the late 1970s to better identify children who died of abuse or neglect; fetal and infant mortality review (FIMR) began in the mid-1980s as a response to the stagnant rates of infant mortality. Today, there are >1350 CDR teams and >150 FIMR teams across the United States, including in tribal communities, territories, and freely associated states. Since the 1990s, the Health Resources and Services Administration's Maternal and Child Health Bureau has supported fetal, infant, and child death review work through funding and thought leadership. The Health Resources and Services Administration-funded National Center for Fatality Review and Prevention provides support to CDR and FIMR teams, including a standardized data collection system for use by state and local CDR and FIMR teams. Although distinct processes, CDR and FIMR both use a public health approach to identify system gaps contributing to early death and make recommendations that impact programmatic and policy changes at the local, state, and national levels. Although progress has been made in standardizing data collection and deepening our understanding of fetal, infant, and child deaths, opportunities persist for preventing future deaths.

Stone Babies: A Pictorial Essay With Insights From 25 Museal Lithopaedions.

BACKGROUND: Lithopaedion, or "stone baby," represents an exceptionally rare clinical phenomenon with fewer than 350 documented cases existing in the medical literature. This condition arises when an advanced extrauterine pregnancy ceases its developmental trajectory and undergoes a lithification process, potentially resulting in a calcified mass with fetal-like morphology. Typically, lithopaedions remain asymptomatic for decades, but may occasionally elicit acute symptoms necessitating medical intervention. However, predominantly, these entities are incidental findings discovered during radiological examinations or autopsies. RESULTS: In this article, we present a comprehensive overview of 25 lithopaedion cases, including unreported cases from several European medical museums. When feasible, additional radiological imaging was conducted to enhance diagnostic clarity. Furthermore, this article situates lithopaedions within a broader historical perspective and a detailed etiopathogenetic framework, elucidating the physiological and pathological mechanisms contributing to their formation. The phenomenon of lithopaedion is a testimony to the complex and often enigmatic nature of the human body. CONCLUSIONS: By compiling and scrutinizing a substantial number of cases, this review offers valuable insights into the clinical implications of lithopaedions. Furthermore, it highlights the necessity for ongoing research and meticulous documentation of rare medical conditions like this, in order to contribute to a deeper understanding of extraordinary phenomena.

Investigating genotype by environment interaction for beef cattle fertility traits in commercial herds in northern Australia with multi-trait analysis.

BACKGROUND: Genotype by environment interactions (GxE) affect a range of production traits in beef cattle. Quantifying the effect of GxE in commercial and multi-breed herds is challenging due to unknown genetic linkage between animals across environment levels. The primary aim of this study was to use multi-trait models to investigate GxE for three heifer fertility traits, corpus luteum (CL) presence, first pregnancy and second pregnancy, in a large tropical beef multibreed dataset (n = 21,037). Environmental levels were defined by two different descriptors, burden of heat load (temperature humidity index, THI) and nutritional availability (based on mean average daily gain for the herd, ADWG). To separate the effects of genetic linkage and real GxE across the environments, 1000 replicates of a simulated phenotype were generated by simulating QTL effects with no GxE onto real marker genotypes from the population, to determine the genetic correlations that could be expected across environments due to the existing genetic linkage only. Correlations from the real phenotypes were then compared to the empirical distribution under the null hypothesis from the simulated data. By adopting this approach, this study attempted to establish if low genetic correlations between environmental levels were due to GxE or insufficient genetic linkage between animals in each environmental level. RESULTS: The correlations (being less than <0.8) for the real phenotypes were indicative of GxE for CL presence between ADWG environmental levels and in pregnancy traits. However, none of the correlations for CL presence or first pregnancy between ADWG levels were below the 5th percentile value for the empirical distribution under the null hypothesis from the simulated data. Only one statistically significant (P < 0.05) indication of GxE for first pregnancy was found between THI environmental levels, where rg = 0.28 and 5th percentile value = 0.29, and this result was marginal. CONCLUSIONS: Only one case of statistically significant GxE for fertility traits was detected for first pregnancy between THI environmental levels 2 and 3. Other initial indications of GxE that were observed from the real phenotypes did not prove significant when compared to an empirical null distribution from simulated phenotypes. The lack of compelling evidence of GxE indicates that direct selection for fertility traits can be made accurately, using a single evaluation, regardless of environment.

Comparing methods for risk prediction of multicategory outcomes: dichotomized logistic regression vs. multinomial logit regression.

BACKGROUND: Medical outcomes of interest to clinicians may have multiple categories. Researchers face several options for risk prediction of such outcomes, including dichotomized logistic regression and multinomial logit regression modeling. We aimed to compare these methods and provide guidance needed for practice. METHODS: We described dichotomized logistic regression, multinomial continuation-ratio logit regression, which is an alternative to standard multinomial logit regression for ordinal outcomes, and logistic competing risks regression. We then applied these methods to develop prediction models of survival and neurodevelopmental outcomes based on the NICHD Extremely Preterm Birth Outcome Tool model. The statistical and practical advantages and flaws of these methods were examined. Both discrimination and calibration of the estimated logistic models of dichotomized outcomes and continuation-ratio logit model were assessed. RESULTS: The dichotomized logistic models and multinomial continuation-ratio logit model had similar discrimination and calibration in predicting death and survival without neurodevelopmental impairment. But the continuation-ratio logit model had better discrimination and calibration in predicting neurodevelopmental impairment. The sum of predicted probabilities of outcome categories from the dichotomized logistic models could deviate from 100% substantially, ranging from 87.7 to 124.0%, and the dichotomized logistic model of neurodevelopmental impairment greatly overpredicted low risks and underpredicted high risks. CONCLUSIONS: Estimating multiple logistic regression models of dichotomized outcomes may result in poorly calibrated predictions for an outcome with multiple ordinal categories. Multinomial continuation-ratio logit regression produces better calibrated predictions, constrains the sum of predicted probabilities to 100%, and has the advantages of simplicity in model interpretation, flexibility to include outcome category-specific predictors and random-effect terms for patient heterogeneity by hospital. It also accounts for mutual dependence among multiple categories and accommodates competing risks.

Comparison of two different suction curettage methods in cesarean scar pregnancy treatment.

BACKGROUND: Cesarean scar pregnancy (CSP), the incidence of which is increasing, can lead to life-threatening consequences. In this study, it was aimed to compare the results of two different ultrasound-assisted suction curettage (SC) approaches that we applied to endogenous type CSPs in different time periods. METHODS: Patients who were diagnosed with CSP and treated with SC in the early pregnancy service between January 2012 and March 2019 were included in the study. While classical SC was applied until December 2016, patients were treated with SC modified by us after this date. Demographic characteristics, preoperative clinical findings, intraoperative characteristics and postoperative short-term follow-up of these two groups of patients belonging to different time periods were compared. RESULTS: 34 patients were treated with classic SC (Group 1) and 32 patients with modified SC (Group 2). The amount of decrease in Hemoglobin values measured at the sixth hour postoperatively compared to the preoperative period was found to be less in group 2 (1.01 ± 0.67 g/dl) than in group 1 (1.39 ± 0.85 g/dl) (p = 0.042). The treatment failure rate was found to be lower in group 2 (p = 0.028). According to the results of multiple logistic regression analysis of significant factors associated with treatment outcome, myometrial thickness measurement and the largest gestational diameter measurement were found to be significant independent factors. CONCLUSION: In CSP cases, SC procedure with abdominal ultrasonography is an effective and reliable approach. At the beginning of this surgical procedure, if the gestational sac is removed from the uterine wall with the curettage cannula before suction, the success of the procedure will increase even more.

Male partners' involvement in antenatal care and its associated factors in West-central Ethiopia.

BACKGROUND: Male partner involvement in antenatal care is a key factor that cannot be ignored in the quest for improvement in maternal health and is recommended as an essential intervention to improve maternal and neonatal health outcomes. However, little attention has been given to male partners' involvement in maternity care, particularly in developing countries. OBJECTIVE: This study aimed to assess male partners' involvement in antenatal care and its associated factors among male partners whose wives gave birth within the last one-year in Bichena town, Westcentral, Ethiopia, 2019. METHODS: A community-based cross-sectional study design was conducted from October 1/2018 to June 15/2019, in Bichena town, among 406 male partners. The data was collected by a simple random sampling technique and analyzed using the Statistical Package of the Social Science 23.0 version. Bivariate and multivariable logistic regression analyses were employed to estimate the crude and adjusted odds ratio with a confidence interval of 95% and a P-value of < 0.05 considered statistically significant. RESULTS: In this study, 53.4% [95% CI: 48.3- 58.1%] of male partners had high involvement in antenatal care. The age group of 20-29 years [AOR = 2.14, 95% CI = 1.04-4.38], having primary, secondary, and diploma and above educational level [AOR = 2.04, 95% CI = 1.02-4.07], [AOR = 3.02, 95% CI = 1.49-6.11] and [AOR = 4.03, 95% CI = 2.06-7.89] respectively, ≤ 10 years marriage length [AOR = 2.92, 95% CI = 1.46-5.87], good knowledge of the services provided in antenatal care [AOR = 2.68, 95%, CI = 1.62-4.42], good awareness of the danger signs of pregnancy [AOR = 1.77, 95 CI = 1.10-2.85], favorable attitude towards antenatal care [AOR = 2.62, 95% CI = 1.64-4.19], travel less than 15 min to reach a nearby health facility [AOR = 3.43, 95% CI = 1.54-7.65] and making decision together to seek care in health facility [AOR = 2.44, 95% CI = 1.19-5.03] were associated with male partners involvement in antenatal care. CONCLUSIONS: Male partners' involvement in antenatal care was encouraging in the study area compared to previous studies done in Ethiopia. We suggest strengthening awareness among male partners about their shared responsibility during pregnancy. Male partners should be invited to attend the antenatal care. Policymakers and healthcare planners should design programs and plans that will encourage male partners' involvement in maternal healthcare services utilization.

Service evaluation of an early pregnancy loss support clinic in an inner London early pregnancy unit.

BACKGROUND: Early pregnancy loss (EPL) can have profound implications for physical and psychological health. In the UK, significant variation in service provision exists for women affected by EPL. There is very little guidance on what hospital-based follow-up support services should entail, and how these can be implemented and integrated into current care provision to meet the needs of women who experience EPL. This service evaluation (SE) reports on an Early Pregnancy Loss Support Clinic (EPLSC) in an inner-city Hospital Trust. METHODS: This SE gathered both quantitative and qualitative feedback from women to assess the value of a locally implemented Early Pregnancy Loss Support Clinic (EPLSC). Quantitative feedback was collected using the Short Assessment of Patient Satisfaction (SAPS) questionnaire and the Visual Anxiety Scale (VAS-A), both administered to women attending the EPLSC. Qualitative feedback was collected through semi-structured interviews and focused on four pre-determined themes based on EPL literature - physical health, mental health, role of the bereavement midwife and overall service user experience. Quantitative feedback was summarised using descriptive statistics, while qualitative feedback was analysed using framework analysis. RESULTS: A total of 127 women were invited to the EPLSC, with 110 (87%) attending, and 17 (13%) not attending their appointment. SAPS scores ranged from 21 to 28, indicating that women were either satisfied or very satisfied with the care they received at the EPLSC. Results from VAS-A scores showed that 76 (69%) women reported a decrease in anxiety immediately after attending the EPLSC, compared to 8 (7%) who reported no change or a small increase in anxiety. Qualitative findings highlighted women's concerns around future fertility, the importance of emotional support and the value of connecting with the bereavement midwife. CONCLUSION: An EPLSC that focuses on providing emotional support and reassurance, particularly regarding future fertility, is important to women. Further rigorous evaluation of national disparities in EPL follow-up is urgently needed to assess the gaps in clinical care delivery.

Co-designing postpartum contraceptive services with and for immigrant women in Sweden: lessons learned from the IMPROVE-it project.

BACKGROUND AND AIM: Immigrant women in many high-income countries including Sweden, report unmet need of sexual and reproductive health and rights, and face worse pregnancy outcomes and higher risk of unintended pregnancies. Postpartum contraceptive services are often inadequate to meet their needs. Co-design has shown to reduce health inequities, yet little is known about using this method for postpartum contraceptive service development and even less in collaborating with immigrant populations. The aim of this paper is to describe the co-design process and the strategies that were developed to help develop tailored and acceptable postpartum contraceptive services for immigrant women in Sweden. METHODS: The paper describes a co-design process that took place during 2022-2023, including the cyclical digital consultations with Arabic and Somali speaking immigrant women, midwives and researchers, as well as the outputs from the process. The theoretical framework for the co-design process was the 'Double Diamond' Design Process Model. Data analysis included qualitative content analysis. RESULTS: The co-design process led to the joint development of intervention materials and strategies to improve postpartum contraceptive services. Specifically, the process revealed ideas on how to improve contraceptive counseling within three pre-identified areas of change: improve physical access to contraceptive services; improved communication strategies using visual aids and information charts; and empowerment strategies that focus on reflective practice without assumptions about what a group of women might expect. We found that participants contributed actively to the process with ideas and suggestions, and that the co-design process facilitated positive reflections on ongoing counseling practices. CONCLUSION: The co-design process resulted in the successful and participative development of innovative tools and activities to improve contraceptive counseling services. This approach is original because it involves both immigrant women, often left behind, and midwives delivering the services. Whilst this interplay allowed for careful refinement of services and tools by using an iterative process, it also facilitated reflective midwifery practice.

A novel approach to detecting microduplication in split hand/foot malformation type 3 at the single-cell level: SHFM as a case study.

BACKGROUND: Split hand/foot malformation (SHFM) is a congenital limb deficiency characterized by missing or shortened central digits. Several gene loci have been associated with SHFM. Identifying microduplications at the single-cell level is challenging in clinical practice, and traditional detection methods may lead to misdiagnoses in embryos and pregnant women. RESULTS: In this research, we utilized a low cell count and whole-genome amplification products to employ single nucleotide polymorphism arrays, next-generation sequencing, and third-generation sequencing methods to detect copy number variants of microduplications in a SHFM3 case with limited DNA. Additionally, Karyomapping and combined linkage analysis were conducted to validate the results. CONCLUSIONS: This study establishes a new strategy for identifying microduplications or microdeletions at the single-cell level in clinical preimplantation genetic testing, enhancing the efficiency and accuracy of diagnosing microduplication or microdeletion diseases during IVF-PGT and prenatal diagnosis.

Astaxanthin improves assisted reproductive technology outcomes in poor ovarian responders through alleviating oxidative stress, inflammation, and apoptosis: a randomized clinical trial.

BACKGROUND: Poor ovarian response (POR) to controlled ovarian stimulation (COS) remains challenging, especially in advanced-age women with diminished ovarian reserve, resulting in low live birth rates. Many patients prefer to conceive with their eggs, underscoring the need for improved treatments. This study explores astaxanthin potential as a COS adjuvant to improve ovarian response and assisted reproductive technology (ART) outcomes, considering its impact on oxidative stress (OS), inflammation, and apoptosis, which are key factors in POR. METHODS: In this randomized, triple-blind, placebo-controlled trial, 60 infertile POR patients from POSEIDON Group 4 (the poorest prognosis category, age > 35 and poor ovarian reserve (anti-müllerian hormone < 1.2 ng/ml or antral follicle count < 5) undergoing intracytoplasmic sperm injection were enrolled. Patients were assigned to receive either 12 mg/day AST or placebo for eight weeks. All patients underwent a gonadotropin-releasing hormone antagonist regimen for COS. ART outcomes were compared between groups. Blood serum and follicular fluid (FF) were analyzed for OS markers (superoxide dismutase [SOD], total antioxidant capacity [TAC], and malondialdehyde [MDA]), and pro-inflammatory cytokines (interleukin-6 [IL-6], interleukin-8 [IL-8], and vascular endothelial growth factor [VEGF]) via enzyme-linked immunosorbent assay kits, and cell-free DNA [cfDNA] (apoptotic marker) via ALU quantitative polymerase chain reaction. RESULTS: After the intervention, the AST group exhibited a significant elevation in serum (P = 0.013) and TAC (P = 0.030), accompanied by a significant reduction in serum MDA (P = 0.005). No significant differences between AST and placebo groups were observed in OS markers in FF. AST group showed significant reductions in the serum IL-6 (P < 0.001), IL-8 (P = 0.001), and VEGF (P = 0.002) levels following AST therapy. In the AST group, FF levels of IL-6 (P = 0 < 001), IL-8 (P = 0.036), VEGF (P = 0.006), and cfDNA (P < 0.001) were significantly lower than in the placebo group. Between-group comparisons showed significant differences in the alterations of serum SOD (P = 0.027), IL-6 (P < 0.001), and IL-8 (P = 0.035) levels between AST and placebo groups. The AST group showed significant increases in the number of retrieved oocytes (P = 0.003), MII oocytes (P = 0.004), frozen embryos (P = 0.037), and high-quality embryos (P = 0.014) compared to the placebo group. CONCLUSION: AST shows promise as a COS adjuvant therapy, potentially enhancing some ART outcomes in POR through alleviating OS, inflammation, and apoptosis.

Growth velocity of fetal sacrococcygeal teratoma as predictor of perinatal morbidity and mortality: multicenter study.

OBJECTIVE: To identify prenatal predictors of poor perinatal outcome in fetuses with isolated sacrococcygeal teratoma (SCT). METHODS: This was a retrospective study of fetuses with isolated (non-syndromic) SCT managed at one of five pediatric surgery and/or fetal medicine centers between January 2007 and December 2017. The primary outcome was the occurrence of poor perinatal outcome, defined as prenatal death (including termination), or neonatal death or severe compromise (hemorrhagic shock). Data regarding prenatal diagnosis (sonographic features both at referral and at the last ultrasound examination before pregnancy outcome, assessment of SCT growth velocity), perinatal complications and outcome, and neonatal course were analyzed to determine prenatal SCT characteristics associated with adverse perinatal outcome. RESULTS: Fifty-five fetuses were included, diagnosed with isolated SCT at a median gestational age of 22 (interquartile range, 18-23) weeks. There was a poor perinatal outcome in 31% (n = 17) of these cases, including intrauterine fetal demise (4%, n = 2), pregnancy termination (13%, n = 7) and neonatal severe compromise (15%, n = 8), leading to neonatal death in five cases. The overall survival rate after prenatal diagnosis of isolated SCT was 75% (n = 41 of 55). Earlier gestational age at diagnosis (P = 0.02), large tumor volume at referral (P < 0.001), presence of one or more hemodynamic complications (P = 0.02), fast tumor growth velocity (P < 0.001) and high tumor grade (highest tumor grade ≥ 3) (P = 0.049) were associated with poor perinatal outcome on univariate analysis. On stepwise logistic regression analysis, tumor growth velocity was the only remaining independent factor associated with poor perinatal outcome (odds ratio (OR) (per 1-mm/week increase), 1.48 (95% CI, 1.22-1.97), P = 0.001). The best predictive cut-off of tumor growth velocity for poor perinatal outcome was 7 mm/week (OR, 25.7 (95% CI, 5.6-191.3), P < 0.001), yielding a sensitivity of 88% and a specificity of 77%. CONCLUSIONS: Approximately 30% of fetuses with a diagnosis of isolated SCT have poor perinatal outcome. Tumor growth velocity ≥ 7 mm/week appears to be an appropriate discriminative cut-off for poor perinatal outcome. These results could help to inform prenatal management and counseling of parents with an affected pregnancy. © 2024 The Author(s).

Association between adenomyosis volume and adverse perinatal outcomes: multicenter cohort study.

OBJECTIVE: To assess the association between adenomyosis volume, as a reflection of its severity, and the risk of adverse perinatal outcomes. METHODS: This multicenter retrospective cohort study was conducted at a comprehensive tertiary care institution and a tertiary maternal and child healthcare hospital, which are the main types of hospital providing maternal medical care in China. The study included pregnant women without adenomyosis (non-AD cohort) who delivered between 1 January 2021 and 31 December 2021, and women with pregnancy complicated by adenomyosis (AD cohort) who delivered between 1 January 2020 and 31 December 2022. Adenomyosis was diagnosed and measured using transvaginal or transabdominal ultrasound up to 14 weeks of gestation. The adenomyosis volume (V) was calculated based on the sonographic measurement of three dimensions, using the formula V = (length × width × thickness) × 4/3π. Univariate and multivariate logistic regression analyses were conducted to assess the association between adenomyosis and the risk of pregnancy complications. We also performed a sensitivity analysis among 226 pregnancies complicated by adenomyosis that had volume measurements available and 10 507 pregnancies without adenomyosis, using as a threshold for severe adenomyosis the 3rd quartile of adenomyosis volume. RESULTS: The study group included 10 507 pregnant women in the non-AD cohort and 321 in the AD cohort. Pregnancies complicated by adenomyosis had an increased risk of preterm birth < 37 weeks of gestation (adjusted odds ratio (aOR), 2.39 (95% CI, 1.65-3.48)), spontaneous preterm birth < 37 weeks of gestation (aOR, 2.57 (95% CI, 1.54-4.28)), placenta previa (aOR, 2.57 (95% CI, 1.41-4.67)), cervical incompetence (aOR, 9.70 (95% CI, 4.00-23.55)) and abnormal fetal presentation (aOR, 2.04 (95% CI, 1.39-3.00)), and there was also a non-significant trend toward increased risk of pre-eclampsia (aOR, 1.64 (95% CI, 0.94-2.85)). Sensitivity analysis revealed there was a greater risk in pregnancies with severe (≥ 757.5 cm3) vs mild adenomyosis of preterm birth < 37 weeks of gestation (aOR, 5.50 (95% CI, 2.80-10.82) vs aOR, 1.73 (95% CI, 0.98-3.05)), pre-eclampsia (aOR, 4.94 (95% CI, 2.11-11.58) vs aOR, 1.03 (95% CI, 0.41-2.58)), placenta previa (aOR, 6.37 (95% CI, 2.39-17.04) vs aOR, 1.58 (95% CI, 0.60-4.19)) and cervical incompetence (aOR, 12.79 (95% CI, 2.87-56.93) vs aOR, 4.97 (95% CI, 1.25-19.77)) compared to pregnancies without adenomyosis. The risk of spontaneous preterm birth < 37 weeks and the risk of abnormal fetal presentation was similar between the two subgroups. CONCLUSION: Pregnancies complicated by adenomyosis, particularly those with severe adenomyosis, have an increased risk of pregnancy complications, including preterm birth, spontaneous preterm birth, placenta previa, cervical incompetence and abnormal fetal presentation. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Intrauterine growth-restricted pregnant rats, from placental ischemic dams, display preeclamptic-like symptoms: A new rat model of preeclampsia.

Preeclampsia (PE) is characterized by de novo hypertension (HTN) and is often associated with intrauterine growth restriction (IUGR). Hallmarks of PE are placental ischemia, decreased nitric oxide (NO) bioavailability, oxidative stress (OS), and organ damage in the kidneys and brain. This study aims to characterize a new model of PE using pregnant IUGR rats from hypertensive placental ischemic dams. It is hypothesized that pregnant IUGR rats from hypertensive placental ischemic dams will have elevated blood pressure (BP), OS, and organ damage. In this study, pregnant rats are divided into two groups: normal pregnant (NP) and hypertensive placental ischemic dams (RUPP). Offspring from NP and RUPP dams were mated at 10 weeks of age to generate pregnant IUGR (IUGR Preg) and pregnant control (CON Preg) rats. BP and other markers of PE were evaluated during late gestation. Pregnant IUGR rats had elevated BP and systemic OS. The maternal body weight of pregnant IUGR rats and their pups' weights were decreased, while the brains were enlarged with elevated OS. In summary, pregnant IUGR rats, born from hypertensive placental ischemic dams, have HTN and increased systemic and brain OS, with larger brain sizes and smaller pups. Furthermore, this study shows that pregnant IUGR rats exhibit a preeclamptic-like phenotype, suggesting a new epigenetic model of PE.

Isolation and pathogenicity of a highly virulent group III porcine Getah virus in China.

Introduction: Getah virus (GETV) is a multi-host virus found in pigs, horses, and blue foxes. Clinically, GETV can cause fever, diarrhea, and reproductive disorders in pigs, representing significant threats to pig breeding. At present, few studies have examined the pathogenicity of GETV in pigs of different ages. Methods: In the present study, a new strain, named GETV-QJ, was isolated from clinically ill pigs, and whole genome sequencing analysis was performed. Besides the pathogenicity of piglets and pregnant sows of this strain was further studied. Results: the results illustrated that the strain belonged to group III. The strain had 93.6%-96.3% homology with other subtypes, and its homology with the same subtype strain ranged 96.5%-99%. Further studies on the pathogenicity of the virus indicated that this strain caused severe diarrhea, fever, and intestinal and lung damage in 7-day-old piglets, resulting in their death. The piglet survival rate was 0%. In pregnant sows, this strain did not cause fever, death, or abortion, but it induced viremia, which affected the farrowing performance of sows and led to reduced piglet survival. Discussion: In this study, we isolated a highly virulent group III and comprehensively established a pathogenic model of GETV in piglets and sows, providing a reference and guidance for the prevention and control of this infection.
