Adverse Pregnancy Outcomes In Women Research Articles

Specific antibody responses to Qβ-displayed Plasmodium falciparum-derived UB05 and MSP3 proteins in mother-neonate couples.

Malaria blood-stage parasite is a critical pathogenic stage responsible for serious adverse outcomes in pregnant women and their neonates. Immunoglobulin G (IgG) antibody responses specific to various asexual blood-stage antigens were well reported in non-pregnant individuals. However, little is still known during placental malaria. To assess the antibody responses specific to Plasmodium falciparum-derived MSP3 and UB05 malaria vaccine candidates in mother-neonate couples, mother's peripheral blood and neonate's cord blood samples were collected at delivery. After malaria diagnostic, plasma levels of IgG and IgG subclass responses specific to UB05, MSP3 and UB05-MSP3 were determined using ELISA. As outcomes, both mothers and neonates had significantly higher IgG responses to UB05 and UB05-MSP3 compared to anti-MSP3 IgG (p < 0.05), irrespective of malaria status. Significant negative correlations were observed between IgG levels specific to the three antigens and parasitaemia (p < 0.01). Anti-UB05 and anti-UB05-MSP3 IgG levels in neonates showed a significant positive correlation with the corresponding mothers' antibodies (rs = 0.25 with p = 0.04; rs = 0.31 with p = 0.01, respectively). UB05MSP3-specific IgG3 and IgG1 subclass responses were significantly higher than the IgG4 subclass (p < 0.01). The neonates IgG1 and IgG3 levels positively correlated with the corresponding antibody subclasses of mothers. These findings suggest an association between UB05 and UB05-MSP3-specific antibody responses and malaria control during pregnancy. Maternal-foetal transfer of MSP3 and UB05-specific IgG occurs during pregnancy, suggesting the interest in the future malaria vaccination strategies in pregnant women to generate early protective immunity in baby against malaria.

Dynamic prediction of pregnancy outcome after previous stillbirth or perinatal death: pilot study to establish proof-of-concept and explore method feasibility.

To establish proof-of-concept for the dynamic prediction of adverse pregnancy outcome in women with a history of stillbirth or perinatal death, repeatedly throughout the pregnancy. A retrospective cohort study of women in a subsequent pregnancy following previous perinatal loss, who received antenatal care at a tertiary hospital between January 2014 and December 2017, was used as the basis for exploratory prognostic model development. Models were developed to repeatedly predict a composite adverse outcome (stillbirth or neonatal death, 5-min Apgar score < 7, umbilical artery pH ≤ 7.05, admission to the neonatal intensive care unit for longer than 24 h, preterm birth (< 37 completed weeks) or birth weight < 10th centile) using the findings of sequential ultrasound scans for fetal biometry and umbilical and uterine artery Doppler. In total, 506 participants were eligible, of whom 504 were included in the analysis. An adverse pregnancy outcome was experienced by 110 (22%) participants. The ability to predict the composite outcome using repeated head circumference and estimated fetal weight measurements improved as the pregnancy progressed (e.g. area under the receiver-operating-characteristics curve improved from 0.59 at 24 weeks' gestation to 0.74 at 36 weeks' gestation), supporting proof-of-concept. Predictors to include in dynamic prediction models were identified, including ultrasound measurements of fetal biometry, umbilical and uterine artery Doppler and placental size and shape. The present study supports proof-of-concept for dynamic prediction of adverse outcome in pregnancy following prior stillbirth or perinatal death, which could be used to identify risks earlier in pregnancy, while highlighting methodological challenges and requirements for subsequent large-scale model development studies. © 2024 The Author(s).

A model of prevention of mother-to-child transmission and health management team for improving adverse outcomes of pregnancy syphilis in Ningxia, China

Regional variations exist in the implementation of Syphilis Mother-to-Child Transmission Prevention (PMTCT). Thus, it is crucial to assess the effectiveness of this model in the Ningxia region and explore the supplementary role of Health Management Teams (HMT). This study established the PMTCT + HMT model and examined its impact on adverse outcomes in pregnant women with syphilis infection. The majority of participants were urban residents, married, had a minimum high school education, and held public positions; 36.7% and 26.7% were from minority ethnic groups. The PMTCT + HMT model enhanced participants’ knowledge, rates of voluntary counseling, and testing. The incidence of adverse pregnancy outcomes (miscarriages, preterm births, stillbirths) significantly decreased, and adverse neonatal outcomes (low birth weight, neonatal mortality, congenital syphilis) were notably reduced. Simultaneously, we identified factors associated with adverse outcomes, including non-residency, unmarried status, lower educational attainment, minority ethnicity, primary syphilis, and positive titers. Thus, HMT may be an effective intervention to enhance the effect of PMTCT for syphilis. The unique population structure in Ningxia is closely linked to adverse outcomes, highlighting the significance of providing equitable treatment for vulnerable populations.

Migraine in antiphospholipid syndrome and hereditary thrombophilia: pregnancy-related clinical and diagnostic features and therapeutic issues

Introduction. Migraine is one of the most common primary headaches and a risk factor for cardiovascular and cerebrovascular diseases. Antiphospholipid syndrome (APS) and hereditary thrombophilia (HT) causing pathological pregnancy are highly associated with migraine. Timely migraine recognition related to APS and HT facilitates earlier initiation of thrombophilia pathogenetic therapy and prevention of potential complications.Aim: to analyze the literature data on migraine clinical and diagnostic features in APS and HT as well as pregnancy-related therapeutic issues.Materials and Methods. A search for scientific literature was conducted in electronic databases including PubMed, Google Scholar, eLibrary from 2004 until May 2024. The search methodological basis included the presence of the following keywords and their combinations in Russian and English: "migraine", "antiphospholipid syndrome", "thrombophilia", "migraine and pregnancy", "migraine and thrombophilia", "migraine and cardiovascular diseases". As a result, a total of 184 publications were identified. Next, 62 articles were included in the review.Results. At the current stage, neurologists have no means to diagnose migraine in APS and HT based on headache-intrinsic characteristics. Pregnancy increases a risk of thrombotic complications. A migraine observed in patient's history should be crucial while assessing pregnancy-related obstetric risk. While diagnosing migraine, neurologists need to examine patient obstetric history. The data on most effective and safe therapy for pregnancy-related migraine attacks remain scarce.Conclusion. The frequent association between APS and HT with migraine, the lack of clear migraine clinical features in thrombophilia, patients’ reproductive age, and the high risk of thrombotic complications necessitate collaboration between neurologists and obstetricians-gynecologists for timely diagnostics and management of such patients. The impact of various types of antithrombotic therapy on migraine course requires further clarification. It is promising to conduct studies able to determine of whether migraine attack prevention can avoid adverse pregnancy outcomes in women with former migraine.

Brief Report: Subsequent Pregnancies in the IMPAACT 2010/VESTED Trial: High Rate of Adverse Outcomes in Women Living With HIV

Introduction: Women with HIV (WHIV) have higher risks of adverse pregnancy outcomes, particularly in the absence of antiretroviral treatment (ART), and timing of ART may impact risk. Methods: In the International Maternal Pediatric Adolescent AIDS Clinical Trials 2010/VESTED study, 643 pregnant WHIV in 9 countries were randomized in a 1:1:1 ratio to initiate ART: dolutegravir (DTG)+emtricitabine (FTC)/tenofovir alafenamide (TAF), DTG+FTC/tenofovir disoproxil fumarate (TDF), or efavirenz (EFV)/FTC/TDF. We describe adverse pregnancy outcomes in women with a subsequent pregnancy during 50 weeks of postpartum follow-up: spontaneous abortion (&lt;20 weeks), stillbirth (≥20 weeks), preterm delivery (&lt;37 weeks), and small for gestational age. Results: Of 643 women, 19 (3%) had 20 subsequent pregnancies while receiving ART at conception: DTG/FTC/TAF (3), DTG/FTC/TDF (2), EFV/FTC or lamivudine (3TC)/TDF (12), EFV/abacavir/3 TC (1), and no ART (1). Four spontaneous abortions, 3 stillbirths, and 1 induced abortion occurred. Three (25%) of 12 liveborn infants were preterm (24, 26, and 36 weeks of gestation). Only 12 subsequent pregnancies (60%) resulted in live birth, and at least 1 adverse pregnancy outcome occurred in 11 of 19 (58%) (induced abortion excluded). Of 7 women who experienced spontaneous abortion/stillbirth in the subsequent pregnancy, 4 experienced a stillbirth and 1 a neonatal death as outcomes of their earlier index pregnancy. No congenital anomalies were reported. Conclusions: Adverse pregnancy outcomes were common in this cohort of WHIV who conceived on ART shortly after an index pregnancy, 35% ended in stillbirth or spontaneous abortion. The majority of fetal losses occurred in women with recent prior pregnancy loss. Data from larger cohorts of WHIV conceiving on ART and surveillance are needed to elucidate rates and predictors of adverse pregnancy outcome.

Adverse pregnancy outcomes for women with endometriosis: a systematic review and meta-analysis.

This study aimed at assessing the adverse outcomes of pregnancy in women with endometriosis. The Cochrane, Embase and PubMed databases were searched for identifying the required studies published before June 2019. Meta-analyses of relative risk (RR) were performed under the random-effects model to estimate the risk of selected adverse outcomes of pregnancy in females with endometriosis. Twenty-eight studies (53,141 women with and 2,355,923 women without endometriosis data) were selected for meta-analysis. Endometriosis bearing females had a significantly higher risk placenta previa (RR 3.92 [95% CI 2.48-6.20]), miscarriage (RR 1.31 [95% CI 1.06-1.61), gestational hypertension (RR 1.30 [95% CI 1.02-1.65]), cesarean section (RR 1.48 [95% CI 1.33-1.65]) and preeclampsia (RR 1.18 [95% CI 1.09-1.28]). The incidence of placental abruption was not statistically significant between the groups (RR 3.62 [95% CI [0.99-13.28]). Women suffering from endometriosis are at higher risks of miscarriage, preterm birth, gestational hypertension, placenta previa, cesarean section, and preeclampsia.

Gestational Outcomes Related to the Occurrence of Gestational Diabetes Mellitus: A Cohort Study

Background: Gestational diabetes mellitus (GDM) is the main cause of hyperglycemia in pregnancy and is related to complications throughout the gestational and post-partum period. Objectives: To analyze the pregnancy outcomes related to the occurrence of GDM in women and their offspring. Methods: Third-trimester pregnant women were interviewed and monitored until childbirth. The diagnosis of GDM, blood glucose ≥ 92 mg/dL, was defined by the criteria of the International Association of the Diabetes and Pregnancy Study Groups (IADPSG). Results: A total of 138 women participated, and there were 136 births (due to 2 fetal losses); 23 (16.7%) were diagnosed with GDM. The risk of complications during childbirth was higher among pregnant women with GDM (RR 3.40; 95%CI 1.65–7.00), as was the occurrence of cesarean birth (RR 1.9; 95%CI 1.46–2.59). The occurrence of preterm birth did not show a significant difference between GDM/non-GDM groups. There was a non-significant association in adjusted analyses of macrosomia (birth weight ≥ 4000 g) among newborns born to mothers with GDM (RR 1.27; 95%CI 0.67–2.38). For newborns born to pregnant women with GDM, there was a higher risk for the following outcomes: large for gestational age (LGA) (3.29 95%CI 1.62–6.64), low Apgar (4.98 95%CI 2.32–10.69), and birth asphyxia (9.51 95%CI 3.42–26.48). Conclusions: The findings reinforce that GDM is an important risk factor for adverse pregnancy outcomes for women and their offspring.

Pregnancy in patients affected by axial-spondyloarthritis: a narrative review of disease activity and obstetric outcomes.

This review aims to summarize the most recent and updated data on pregnancy in patients with axial spondyloarthritis (axSpA), focusing on the recurrence of pregnancy-related complications, the disease activity throughout gestation and the postpartum, and the latest indications for the treatments of future mothers. We have conducted a narrative review with an online literature search on Medline and PubMed. We selected only studies written in English published until January 2024, including observational and retrospective studies, meta-analyses, and systematic reviews. Proper preconception counseling and maternal-fetal monitoring are necessary to ensure the best outcome for both the mother and her baby. Despite the limited and conflicting evidence about the prevalence of adverse pregnancy outcomes in women with axSpA compared to healthy controls, primary findings demonstrate an increased risk of preterm delivery (PTD), low birth weight (LBW), and elective cesarean section (CS). Concerning disease activity, data suggests that 25-80% of women with ankylosing spondylitis experience disease flares during pregnancy, particularly around 20 weeks of gestation. On the contrary, the data on the postpartum disease flare are heterogeneous. The use of biological drugs in pregnancy is safe and effective in controlling disease activity. Data on pregnancy outcomes in patients with axSpA are scarce and discordant. Probably the difference in maternal disease classification, the evolution of treatment indications, and the differences emerging from study designs can account for these discrepancies. The main evidence shows an increased risk of PTD, LBW, and elective CS (although the latter may reflect cultural influences rather than medical needs due to axSpA itself). The majority of drugs used to treat axSpA, including TNFi, are safe in pregnancy without harming mothers or fetuses. Further data is needed to clarify many controversial aspects in this area.

COVID-19 diagnosis, vaccination during pregnancy, and adverse pregnancy outcomes of 865,654 women in England and Wales: a population-based cohort study

The extent to which COVID-19 diagnosis and vaccination during pregnancy are associated with risks of common and rare adverse pregnancy outcomes remains uncertain. We compared the incidence of adverse pregnancy outcomes in women with and without COVID-19 diagnosis and vaccination during pregnancy. We studied population-scale linked electronic health records for women with singleton pregnancies in England and Wales from 1 August 2019 to 31 December 2021. This time period was divided at 8th December 2020 into pre-vaccination and vaccination roll-out eras. We calculated adjusted hazard ratios (HRs) for common and rare pregnancy outcomes according to the time since COVID-19 diagnosis and vaccination and by pregnancy trimester and COVID-19 variant. Amongst 865,654 pregnant women, we recorded 60,134 (7%) COVID-19 diagnoses and 182,120 (21%) adverse pregnancy outcomes. COVID-19 diagnosis was associated with a higher risk of gestational diabetes (adjusted HR 1.22, 95% CI 1.18-1.26), gestational hypertension (1.16, 1.10-1.22), pre-eclampsia (1.20, 1.12-1.28), preterm birth (1.63, 1.57-1.69, and 1.68, 1.61-1.75 for spontaneous preterm), very preterm birth (2.04, 1.86-2.23), small for gestational age (1.12, 1.07-1.18), thrombotic venous events (1.85, 1.56-2.20) and stillbirth (only within 14-days since COVID-19 diagnosis, 3.39, 2.23-5.15). HRs were more pronounced in the pre-vaccination era, within 14-days since COVID-19 diagnosis, when COVID-19 diagnosis occurred in the 3rd trimester, and in the original variant era. There was no evidence to suggest COVID-19 vaccination during pregnancy was associated with a higher risk of adverse pregnancy outcomes. Instead, dose 1 of COVID-19 vaccine was associated with lower risks of preterm birth (0.90, 0.86-0.95), very preterm birth (0.84, 0.76-0.94), small for gestational age (0.93, 0.88-0.99), and stillbirth (0.67, 0.49-0.92). Pregnant women with a COVID-19 diagnosis have higher risks of adverse pregnancy outcomes. These findings support recommendations towards high-priority vaccination against COVID-19 in pregnant women.

Obstetric Outcomes in Women on Lithium: A Systematic Review and Meta-Analysis.

Background/Objectives: Lithium taken during pregnancy was linked in the past with increased risk for foetal/newborn malformations, but clinicians believe that it is worse for newborn children not to treat the mothers' underlying psychiatric illness. We set to review the available evidence of adverse foetal outcomes in women who received lithium treatment for some time during their pregnancy. Methods: We searched four databases and a register to seek papers reporting neonatal outcomes of women who took lithium during their pregnancy by using the appropriate terms. We adopted the PRISMA statement and used Delphi rounds among all the authors to assess eligibility and the Cochrane Risk-of-Bias tool to evaluate the RoB of the included studies. Results: We found 28 eligible studies, 10 of which met the criteria for inclusion in the meta-analysis. The studies regarded 1402 newborn babies and 2595 women exposed to lithium. Overall, the systematic review found slightly increased adverse pregnancy outcomes for women taking lithium for both the first trimester only and any time during pregnancy, while the meta-analysis found increased odds for cardiac or other malformations, preterm birth, and a large size for gestational age with lithium at any time during pregnancy. Conclusions: Women with BD planning a pregnancy should consider discontinuing lithium when euthymic; lithium use during the first trimester and at any time during pregnancy increases the odds for some adverse pregnancy outcomes. Once the pregnancy has started, there is no reason for discontinuing lithium; close foetal monitoring and regular blood lithium levels may obviate some disadvantages of lithium administration during pregnancy.

Pregnancy outcome predictors in systemic lupus erythematosus: a systematic review and meta-analysis

To enhance patient-tailored preconception risk assessment for women with systemic lupus erythematosus (SLE), knowledge on risk factors associated with adverse pregnancy outcomes is required. Therefore, we did a systematic review and meta-analysis to identify and provide unambiguous effect sizes of preconception predictors of pregnancy outcomes in women with SLE. In this systematic review and meta-analysis, we searched PubMed and Embase for studies reporting preconception predictors of pregnancy outcomes in women with SLE, from database inception to Aug 22, 2023. Studies were included if they presented original, quantitative data on pregnant women with SLE and reported on preconception risk factors on at least one of the outcomes as defined in the protocol. Studies were excluded if they had a sample size of less than 20 patients, were restricted to multiple pregnancies, had unclear timing of prognostication, or exclusively reported a composite outcome. Literature screening, data extraction, and risk-of-bias assessment (quality in prognostic studies tool) were done by two reviewers independently, in a blinded, standardised manner. The reported outcomes included livebirth, pre-eclampsia, small for gestational age, preterm birth, pregnancy loss before and after 20 weeks of gestation, and SLE flares. We computed pooled univariate odds ratios (ORs) and 95% CIs using a random effects model. We assessed heterogeneity using the I2 statistic and prediction intervals. This study is registered with PROSPERO, CRD42022344732. Of the 6705 unique articles identified, 72 (1·1%) were included in the meta-analysis, comprising 10 355 pregnancies in 8065 women with SLE. One potentially eligible study was retracted and therefore removed from our analysis. Previous lupus nephritis was associated with decreased livebirth probability (OR 0·62 [95% CI 0·47-0·81]; I2=0%), increased risk of preterm birth (2·00 [1·55-2·57]; I2=17%), and increased risk of pre-eclampsia (3·11 [2·35-4·12]; I2=0%). Chronic hypertension was associated with increased risk of disease flare (2·50 [1·74-3·58]; I2=0%), preterm birth (2·65 [1·87-3·77]; I2=0%), and pre-eclampsia (5·86 [3·41-10·06]; I2=33%). SLE disease activity at conception or preconception was associated with increased risk of preterm birth (2·91 [1·96-4·33]; I2=21%) and pre-eclampsia (2·32 [1·40-3·83]; I2=0%). Secondary antiphospholipid syndrome was associated with decreased livebirth probability (0·40 [0·27-0·58]; I2=0%), increased risk of pregnancy loss after 20 weeks of gestation (2·77 [1·44-5·31]; I2=0%), and increased risk of preterm birth (1·65 [1·29-2·11]; I2=0%). Across studies, risk-of-bias assessment suggested considerable bias in study attrition and confounding. We identified previous lupus nephritis, chronic hypertension, SLE disease activity before and at conception, and secondary antiphospholipid syndrome as predictors of adverse pregnancy outcomes in women with SLE. These findings contribute to an optimal patient-tailored risk assessment in preconception counselling. None.

Decreased complexity of glucose time series index associated with adverse pregnancy outcomes in gestational diabetes mellitus.

We investigated the relationship between the complexity of the glucose time series index (CGI) during pregnancy and adverse pregnancy outcomes in women with gestational diabetes mellitus (GDM). In this retrospective cohort study, 388 singleton pregnant women with GDM underwent continuous glucose monitoring (CGM) at a median of 26.86 gestational weeks. CGI was calculated using refined composite multiscale entropy based on CGM data. The participants were categorized into tertiles according to their baseline CGI (CGI <2.32, 2.32-3.10, ≥3.10). Logistic regression was used to assess the association between CGI and composite adverse outcomes or large for gestational age (LGA). The discrimination performance of CGI was estimated using receiver operating characteristic analysis. Of the 388 participants, 71 (18.3%) had LGA infants and 63 (16.2%) had composite adverse outcomes. After adjustments were made for confounders, compared with those with a high CGI (CGI ≥3.10), participants with a low CGI (CGI <2.32) had a higher risk of composite adverse outcomes (odds ratio: 12.10, 95% confidence interval: 4.41-33.18) and LGA (odds ratio: 12.68, 95% confidence interval: 4.04-39.75). According to the receiver operating characteristic analysis, CGI was significantly better than glycated haemoglobin and conventional CGM indicators for the prediction of adverse pregnancy outcomes (all p < .05). A lower CGI during pregnancy was associated with composite adverse outcomes and LGA. CGI, a novel glucose homeostasis predictor, seems to be superior to conventional glucose indicators for the prediction of adverse pregnancy outcomes in women with GDM.

Placental human papillomavirus infections and adverse pregnancy outcomes

IntroductionKnowledge on prevalence and association of human papillomavirus (HPV) in third trimester placentae and adverse pregnancy outcomes is limited. We investigated the prevalence of placental HPV at delivery, explored urine HPV characteristics associated with placental HPV and whether placental HPV increased the risk adverse pregnancy outcomes. MethodsPregnant women were enrolled in the Scandinavian PreventADALL mother-child cohort study at midgestation. Human papillomavirus genotyping was performed on placental biopsies collected at delivery (n = 587) and first-void urine at midgestation and delivery (n = 556). Maternal characteristics were collected by questionnaires at gestational week 18 and 34. Adverse pregnancy outcomes were registered from chart data including hypertensive disorders of pregnancy, gestational diabetes mellitus and newborns small for gestational age. Uni- and multivariable regression models were used to investigate associations. ResultsPlacental HPV was detected in 18/587 (3 %). Twenty-eight genotypes were identified among the 214/556 (38 %) with midgestational urine HPV. Seventeen of the 18 women with placental HPV were midgestational HPV positive with 89 % genotype concordance. Midgestational high-risk-(HR)-HPV and high viral loads of Any- or HR-HPV were associated with placental HPV. Persisting HPV infection from midgestation to delivery was not associated with placental HPV. Adverse pregnancy outcomes were seen in 2/556 (0.4 %) of women with placental HPV. DiscussionIn this general cohort of pregnant women, the prevalence of placental HPV was 3 %, and midgestational urinary HPV 38 %. High HPV viral load increased the risk for placental HPV infections. We observed no increased risk for adverse pregnancy outcomes in women with placental HPV.

The influence of uterine fibroids on adverse outcomes in pregnant women: a meta-analysis

ObjectiveThe objective of the meta-analysis was to determine the influence of uterine fibroids on adverse outcomes, with specific emphasis on multiple or large (≥ 5 cm in diameter) fibroids.Materials and methodsWe searched PubMed, Embase, Web of Science, ClinicalTrials.gov, China National Knowledge Infrastructure (CNKI), and SinoMed databases for eligible studies that investigated the influence of uterine fibroids on adverse outcomes in pregnancy. The pooled risk ratio (RR) of the variables was estimated with fixed effect or random effect models.ResultsTwenty-four studies with 237 509 participants were included. The pooled results showed that fibroids elevated the risk of adverse outcomes, including preterm birth, cesarean delivery, placenta previa, miscarriage, preterm premature rupture of membranes (PPROM), placental abruption, postpartum hemorrhage (PPH), fetal distress, malposition, intrauterine fetal death, low birth weight, breech presentation, and preeclampsia. However, after adjusting for the potential factors, negative effects were only seen for preterm birth, cesarean delivery, placenta previa, placental abruption, PPH, intrauterine fetal death, breech presentation, and preeclampsia. Subgroup analysis showed an association between larger fibroids and significantly elevated risks of breech presentation, PPH, and placenta previa in comparison with small fibroids. Multiple fibroids did not increase the risk of breech presentation, placental abruption, cesarean delivery, PPH, placenta previa, PPROM, preterm birth, and intrauterine growth restriction. Meta-regression analyses indicated that maternal age only affected the relationship between uterine fibroids and preterm birth, and BMI influenced the relationship between uterine fibroids and intrauterine fetal death. Other potential confounding factors had no impact on malposition, fetal distress, PPROM, miscarriage, placenta previa, placental abruption, and PPH.ConclusionThe presence of uterine fibroids poses increased risks of adverse pregnancy and obstetric outcomes. Fibroid size influenced the risk of breech presentation, PPH, and placenta previa, while fibroid numbers had no impact on the risk of these outcomes.

Fetal Clinical and Paraclinical Outcomes in HIV-Positive Pregnant Women.

Background Adverse pregnancy outcomes in women with human immunodeficiency virus (HIV) infection remain significantly increased. Untreated maternal infection primarily leads to fetal complications, such as intrauterine growth restriction, stillbirth, or preterm birth. Concerning both maternal and fetal complications that can appear in pregnancy associated with HIV infection, the purpose of the study was to determine fetal and maternal demographic characteristics and the correlation between blood count parameters and poor fetal prognosis. Methods We conducted a quantitative study utilizing document review as the data collection method. This study encompassed a cohort of nine HIV-positive pregnant women who delivered at the Obstetrics and Gynecology Department of the University Emergency Hospital in Bucharest from January 1, 2021, to December 31, 2023. A comparative cohort of nine healthy pregnant women who delivered during the same period in the same facility was selected using stratified random sampling. We examined maternal and fetal demographic parameters and neonatal outcomes, reporting them to paraclinical laboratory data. Results The incidence of pregnancy-related HIV infections was 0.16%. The mean age of patients in the selected group was 29.88 ± 5.53. There was no statistically significant correlation between maternal clinical and paraclinical parameters in the HIV-positive and HIV-negative groups. Although there was a slightly negative difference in the fetal weight at birth, the 1-min APGAR (appearance, pulse, grimace, activity, and respiration) score, and the intrauterine growth restriction between the two groups, there was a statistically significant association between admission to the neonatal intensive care unit (NICU) and the neonates from HIV-positive pregnancies. In our study, we observed preterm deliveries in 22.22% of cases, and we did not record any stillbirths. The 1-min APGAR score was correlated with the value of leukocytes in peripheral blood. Vertical transmission was established to be 11.11% independent of maternal blood count parameters. Conclusion HIV infection during pregnancy leads to a higher risk of admission to the NICU. Fetal leukocytosis is indicative of a lower 1-min APGAR score.The primary emphasis of therapeutic intervention during pregnancy should center on vigilant monitoring of maternal viral load and the timely administration of antiretroviral therapy to enhance fetal outcomes.

Pregnancy Outcomes in Women Who Developed Elevated Blood Pressure and Stage I Hypertension after 20 Weeks, Gestation.

The American College of Obstetrics threshold for hypertension (≥140/90 mm Hg) differs from those of the American College of Cardiology (ACC) and the American Heart Association (AHA). It is unknown if ACC/AHA hypertension levels are associated with adverse pregnancy outcomes (APOs) after 20 weeks gestation. The purpose of this study is to analyze APOs in women with blood pressure (BP) in the elevated or stage 1 range after 20 weeks gestation. This was a secondary analysis of the nuMoM2b prospective cohort study of 10,038 nulliparous, singleton pregnancies between 2010 and 2014. BP was measured at three visits during the pregnancy using a standard protocol. Women without medical comorbidities, with normal BP by ACC/AHA guidelines (systolic BP [SBP] < 120 and diastolic BP [DBP] < 80 mm Hg) up to 22 weeks, were included. Exposure was BP between 22 and 29 weeks gestation: normal (SBP < 120 and DBP < 80 mm Hg), elevated (SBP: 120-129 and DBP < 80 mm Hg), and stage 1 (SBP: 130-139 or DBP: 80-89 mm Hg). The primary outcome was hypertensive disorder of pregnancy (HDP) at delivery. Secondary outcomes included fetal growth restriction (FGR), placental abruption, preterm delivery, and cesarean delivery. Multivariable-adjusted odds ratio (aORs) and 95% confidence intervals (CIs) were estimated using logistic regression models. Of 4,460 patients that met inclusion criteria, 3,832 (85.9%) had BP in the normal range, 408 (9.1%) in elevated, and 220 (4.9%) in stage 1 range between 22 and 29 weeks. The likelihood of HDP was significantly higher in women with elevated BP (aOR: 1.71, 95%CI: 1.18,2.48), and stage 1 BP (aOR: 2.79, 95%CI: 1.84,4.23) compared to normal BP (p < 0.001). Stage 1 BP had twice odds of FGR (aOR: 2.33, 95%CI: 1.22,4.47) and elevated BP had three times odds of placental abruption (aOR: 3.03; 95%CI: 1.24,7.39). Elevated or stage 1 BP >20 weeks of pregnancy are associated with HDP, FGR, and placental abruption. · Elevated and stage 1 BP increases risk for HDP.. · Elevated BP increases risk for placental abruption.. · Stage 1 BP increases risk for FGR..

Determinants of Conception and Adverse Pregnancy Outcomes in Women with Endometriosis: A Longitudinal Study.

Endometriosis, affecting approximately 10% of reproductive-aged women globally, poses significant challenges, including chronic pelvic pain, dysmenorrhea, and infertility. In low- and middle-income countries like India, accessibility to affordable infertility care remains a concern. This multicenter prospective cohort study, conducted across six tertiary care hospitals in India from 2017 to 2022, aims to explore the natural progression of conception and pregnancy outcomes in women with endometriosis. Of the 257 participants, 19.1% conceived during the study, revealing significant geographic and income-based variations (p < 0.001, p = 0.01). Dysmenorrhea (p < 0.001) and dyspareunia (p=0.027) were correlated with conception, while no such associations were found with chronic pelvic pain or menstrual factors. Lesion type, number, and severity showed no conclusive link with conception. Natural conception occurred in 70% of cases, with an average post-surgery conception time of 282.1 days. Live birth rate was 85.7%, while complications included placenta previa (16.4%), preeclampsia (4.1%), and preterm births (4.1%). This study, one of the first in India on endometriosis-related fertility progression, emphasizes the need for comprehensive understanding and management of conception and pregnancy outcomes. Considering India's substantial endometriosis burden, the study recommends prioritizing larger multicenter investigations for a better understanding and effective strategies for infertility management.

Effects of vaginal progesterone and placebo on preterm birth and antenatal outcomes in women with singleton pregnancies and short cervix on ultrasound: a meta-analysis.

Vaginal progesterone in preterm birth and adverse outcomes caused by cervical insufficiency remains controversial. To address it, the effect of vaginal progesterone on preterm delivery and perinatal outcome of single pregnancy women with short cervix (less than 25 mm) was systematically evaluated by meta-analysis. "Vaginal progesterone," "placebo," "ultrasound," "cervix," "singleton pregnancy," "preterm birth," and "antenatal outcomes" were entered to screen clinical studies PubMed, Embase, and the Chinese Biomedical Literature Database (CBM). The study population consisted of women with singleton pregnancies and a short cervix on ultrasound, and were assigned into the progesterone group (n = 1,368) and the placebo group (n = 1,373). Treatment began after the patient was diagnosed with short cervix until delivery. Neonatal survival rate, Neonatal Intensive Care Unit (NICU) admission rate, respiratory distress syndrome (RDS), intraventricular hemorrhage (IVH), neonatal mortality, and birth weight <1,500 g were analyzed. A total of 8 articles, totaling 2,741 study subjects, were enrolled. The progesterone group exhibited an obvious reduced rate of preterm birth at <34 weeks (OR = 0.67, 95% CI: 0.53∼0.84; Z = 3.53, P = 0.004), preterm birth at <32 weeks (OR = 0.46, 95% CI: 0.28∼0.77; Z = 2.99, P = 0.003), NICU admission rate (OR = 0.45, 95% CI: 0.30∼0.66; Z = 0.15, P < 0.0001), RDS rate (OR = 0.42, 95% CI: 0.28∼0.63; Z = 4.25, P < 0.0001), IVH incidence rate (OR = 0.40, 95% CI: 0.17∼0.95; Z = 2.08, P = 0.04), neonatal mortality (OR = 0.25, 95% CI: 0.13∼0.46; Z = 4.39, P < 0.0001), and proportion of neonates with birth weight < 1,500 g (OR = 0.45, 95% CI: 0.32∼0.64; Z = 4.50, P < 0.0001). Vaginal progesterone lowered the incidences of preterm birth and adverse pregnancy outcomes in women with singleton pregnancies and a short cervix.

Development, Validation and Clinical Utility of a Risk Prediction Model for Maternal and Neonatal Adverse Outcomes in Pregnant Women with Hypothyroidism.

This study aimed to create, verify and assess the clinical utility of a prediction model for maternal and neonatal adverse outcomes in pregnant women with hypothyroidism. A prediction model was developed, and its accuracy was tested using data from a retrospective cohort. The study focused exclusively on female patients diagnosed with hypothyroidism who were admitted to a tertiary hospital. The development and validation cohort comprised individuals who gave birth between 1 October 2020 and 31 December 2022. The primary outcome was a combination of crucial maternal and newborn problems (eg premature births, abortions and neonatal asphyxia). The prediction model was developed using logistic regression. Evaluation of the model's performance was conducted based on its ability to discriminate, calibrate and provide clinical value. In total, nine variables were chosen to develop the predictive model for adverse maternal and neonatal outcomes during pregnancy with hypothyroidism. The area under the curve of the model for predicting maternal adverse outcomes was 0.845, and that for predicting neonatal adverse outcomes was 0.685. The calibration plots showed good agreement between the nomogram predictions and the actual observations in both the training and validation cohorts. Furthermore, decision curve analysis suggested that the nomograms were clinically useful and had good discriminative power to identify high-risk mother-infant cases. Two models to predict the risk probability of maternal and neonatal adverse outcomes in pregnant women with hypothyroidism were developed and verified to assist physicians in evaluating maternal and neonatal adverse outcomes throughout pregnancy with hypothyroidism and to facilitate decision-making regarding therapy.

The impact of COVID-19 disease on maternal and neonatal outcomes among birthing women in Jordan

BackgroundPregnant women are considered among the vulnerable groups affected by COVID-19. In addition to the direct effect on maternal health, COVID-19 adversely affects neonatal outcomes. PurposeTo explore the impact of COVID-19 on maternal and neonatal outcomes among birthing women in Jordan. MethodA descriptive comparative retrospective design was used. A self-report questionnaire was used to collect data from 140 conveniently selected women admitted to a large governmental hospital in central Jordan. The participants' data files contained data about the birth outcomes. ResultThe results showed that rates of fetal distress incidence as a reason for emergency cesarean X2 (1, N = 140) = 9.46, p = 0.002, and the need to use electronic fetal heart rate monitoring X2 (1, N = 140) = 6.87, p = 0.009 were higher in mothers infected with COVID-19. The non-infected group reported higher use of analgesics during labor X2 (1, N = 140) = 5.42, p = 0.02, episiotomy occurrence X2 (1, N = 140) = 36.96, p = 0.001, incidence of any laceration during labor X2 (1, N = 140) = 38.60, p = 0.001 and gestational age F (1, 8.926) = 0.003, P < 0.05. ConclusionsThis study indicated that COVID-19 could lead to significant adverse outcomes for pregnant women. It also emphasized the need for more understanding of the implications for newborns born to women infected with COVID-19. Outcomes could serve as a baseline for future studies exploring the effect of COVID-19 on maternal and neonatal outcomes among birthing women.
