Anesthetic approach to pregnant patients with malaria: a narrative review of the literature.

INTRODUCTION: Anesthesiologists play an important role in the management of labor and delivery during acute malaria infection. The peripartum anesthesia considerations for such cases remain unclear. FINDINGS: Important peripartum considerations include the severity of thrombocytopenia and coagulopathy, hemodynamic status and cardiac disease, and the likelihood of central nervous system (CNS) involvement. Several antimalarial drugs may interact with perioperative medications, causing hypoglycemia, methemoglobinemia, or QT prolongation. Labor should usually not be induced. Patient volume status should be optimized pre-induction, but fluids should be administered with caution given the risk of cerebral edema. In case of CNS involvement intracranial pressure should be maintained. Case reports describe the successful use of neuraxial anesthesia but this approach requires further confirmation of safety. Despite the risks accompanying airway management in pregnancy, in some cases, general anesthesia was preferred due to the chance of CNS infection and disease complications. Tight postoperative assessments of neurological and bleeding status are indicated regardless of the mode of delivery. CONCLUSIONS: Despite the prevalence of malaria, the perioperative risk and preferred mode of anesthesia for pregnant patients with acute malaria remain under-researched and outcome data are limited.

The Course of Minipuberty in Daughters of Women with Low Gestational Vitamin D Status.

Minipuberty is a term describing temporary, sex-specific activation of the hypothalamic-pituitary-gonadal axis, which is implicated in the development of male and female genital organs. Sons of women with low vitamin D during gestation were found to be characterized by increased activity of the reproductive axis and faster postnatal growth of genital organs. The current study assesses for the first time the course of minipuberty in female descendants of women with a vitamin D deficit. The study population included three matched groups of infant girls: children born to women with vitamin D deficiency (25OHD concentration below 50 nmol/L), offspring of women with vitamin D insufficiency (25OHD concentration between 50 and 75 nmol/L), and daughters of healthy females (25OHD concentration between 75 and 150 nmol/L). Salivary concentrations of estradiol, progesterone, 17-hydroxyprogesterone and androgens, as well as urine concentrations of FSH and LH, were assayed during the first 18 months of life (once a month in the first 6 months, bimonthly between months 6 and 12, and then every three months). At each visit, beyond hormone measurements, the investigators assessed the size of reproductive organs: ovaries, uterus and breasts. In daughters of mothers with vitamin D deficiency, concentrations of FSH, LH and estradiol were higher and detectable for a longer period of time, while ovarian volume, uterine length and breast diameter were greater than in the remaining groups. Children born to women with vitamin D insufficiency were characterized by higher FSH levels than daughters of healthy females, though the detection period was the same, and both groups differed in breast diameter. These findings suggest that low vitamin D status during gestation leads to more pronounced and longer-lasting activation of the reproductive axis, and is associated with increased dimensions of sexual organs, the magnitude of which depends on the degree of vitamin D deficit.

Effect of perinatal consumption of low-calorie sweetener on maternal health: A systematic review and meta-analysis.

BACKGROUND AND AIMS: Evidence regarding perinatal low-calorie (or artificial) sweetener (LCS) consumption and its effect on maternal health outcomes is limited and inconclusive. The primary outcomes of our systematic review and meta-analysis were the effect of preconception and pregnancy LCS exposure on reproductive and pregnancy outcomes. Secondary outcomes included long-term maternal health. METHODS: A systematic search of electronic databases, including PubMed, Embase, CINAHL, the Cochrane Library, Scopus, Web of Science, PsycINFO, ProQuest Health and Medical, ClinicalTrials.gov and Google Scholar, was conducted up to 20 November 2023. Primary studies, including clinical trials, cohort studies, case-control studies, which reported any LCS consumption during perinatal period and pregnancy and maternal health outcomes were eligible. A random effects model with restricted maximum likelihood estimation was used for the meta-analysis. We appraised the quality of the included studies using the National Institute of Health study quality appraisal tool and the overall quality of evidence using the Grading of Recommendations Assessment, Development, and Evaluation tool. RESULTS: A total of 19 eligible studies with 203,706 participants were included. LCS consumption during pregnancy was associated with 11% increased risk of preterm birth (RR = 1.11, 95% CI: 1.07-1.16, I2 = 0.01%) and 42% increased risk of gestational diabetes (RR = 1.42, 95% CI: 0.98-2.04, I2 = 67.60%) compared with no consumption, however, the effect size for gestational diabetes was not precise as the 95% CI indicated that the effect estimate could range from 2% lower risk to 204% (or 2.04 times) higher risk. We found no association between LCS consumption during pregnancy and gestational weight gain (standardized mean difference (SMD) = 0.04; 95% CI: -0.17 - 0.24, I2 = 41.31%) or gestational age at birth (SMD = 0.00; 95% CI: -0.13 - 0.14, I2 = 80.13%). The effect of LCS consumption on reproductive treatment outcomes were inconsistent. CONCLUSIONS: Based on the evidence available, LCS consumption in pregnancy was associated with increased risk of preterm birth and gestational diabetes. Robust research, such as well-designed randomized trials and large prospective cohort studies, is required to confirm the causal effect of LCS consumption during perinatal period on adverse maternal health outcomes.

Factors influencing late antenatal care of Muslim pregnant women: A predictive correlational study in Aceh, Indonesia.

Background: Late antenatal care (ANC) has significant implications for maternal and infant morbidity and mortality among Muslim pregnant women in Indonesia. Existing literature has primarily focused on gestational weeks at the first ANC contact, with limited attention to the total number of ANC visits. Objective: This study aimed to explore the factors predicting late antenatal care contact among Muslim pregnant women, including the gestational weeks of the first ANC contact and the total number of ANC visits in Aceh, Indonesia. Methods: A predictive correlational study design was utilized. Eighty postpartum women who received late ANC were purposively sampled and included in the study. Data were collected in May 2023 using ANC knowledge, beliefs, and social support questionnaires. Statistical analyses included descriptive statistics, Spearman's rank correlation, Chi-Square tests, and binary logistic regression with the enter method. Results: Pregnant women residing farther from home to ANC services were more likely to have their first ANC contact after 20 weeks than those with a shorter distance (AOR = 1.06; 95% CI: 1.02-1.10; p = 0.007). Additionally, women with a history of multiple abortions were more inclined to have four or more ANC visits compared to those with fewer abortions (AOR = 6.78; 95% CI: 1.64-28.09; p = 0.008). Conclusion: Distance from home to healthcare services emerged as a significant barrier to ANC contact, while a history of abortion appeared to motivate pregnant women to seek ANC more frequently. To address these issues effectively, nurses should consider implementing telemedicine services for ANC provision, integrating information on pregnancy complications to better support pregnant women in their care journey.

Association of circulating minerals and vitamins with pregnancy complications: a Mendelian randomization study.

Background: Though considerable studies suggesting connections between micronutrients and pregnancy complications, current evidence remains inconsistent and lacks causative confirmation. Our study aimed to explore the causal links between them with a two-sample Mendelian randomization (MR) analysis. Methods: Genome-wide association studies (GWAS) data for circulating micronutrients were sourced from GWAS Catalog consortium and PubMed, while data for pregnancy outcomes, including gestational diabetes mellitus (GDM), gestational hypertension (GH), spontaneous abortion (SA), preterm birth (PTB), and stillbirth (SB), were retrieved from the UK Biobank and FinnGen consortia. Causal effects were appraised using inverse variance weighted (IVW), weighted median (WM), and MR-Egger, followed by sensitivity analyses and meta-analysis for validation. Results: Genetically predicted higher vitamin E (OR = 0.993, 95% CI 0.987-0.998; p = 0.005) levels were inversely associated with SA risk. Consistent results were obtained in meta-analysis (OR = 0.99, 95% CI 0.99-1.00; p = 0.005). Besides, a potential positive causality between genetic predisposition to vitamin B12 and SB was identified in both IVW (OR = 0.974, 95% CI 0.953-0.996; p = 0.018) and WM analysis (OR = 0.965, 95% CI 0.939-0.993; p = 0.013). However, no causal relationships were observed between other analyzed circulating micronutrients and pregnancy complications. Conclusion: This study offers compelling evidence of causal associations between circulating levels of vitamins E, B12 and the risk of SA and SB, respectively. These findings are pivotal for pregnancy complications screening and prevention, potentially guiding clinical practice and public health policies toward targeted nutritional interventions.

Criteria and non-criteria antiphospholipid autoantibodies screening in patients with late pregnancy morbidity: A cross-sectional study.

INTRODUCTION: Antiphospholipid syndrome (APS) is a cause of pregnancy morbidity. We aim to determine the frequency of criteria and non-criteria anti-phospholipid (aPL) autoantibodies in patients admitted for unexplained fetal death (UFD), pre-eclampsia (PE) and/or fetal growth restriction (FGR). METHODS: All consecutive patients with UFD, PE and/or FGR followed in the department of Obstetrics, Bichat Hospital, University of Paris, Paris, between January 2019 and December 2021 were screened. Patients with available serum stored from the index pregnancy were included. Patients with previously known APS or twin pregnancy were excluded. Testing for aPL autoantibodies included anti-cardiolipin (aCL), anti-ß2GPI (aß2GPI), anti-phosphatidylethanolamine (aPE), anti-phosphatidylserine/prothrombin (aPS/PT) IgG/IgM and anti-annexin V IgG. When available, placenta specimens were analyzed by a pathologist blinded to the aPL status. All clinical characteristics, pregnancy features, and comorbidities were extracted from electronic medical records. RESULTS: Overall 167 (32 (28.8-35.7) years) patients with UFD (n = 28; 16.8 %), PE (n = 60; 35.9 %) and/or FGR (n = 105; 62.9 %) were screened for aPL autoantibodies. Moderate titers of aPL autoantibodies were detected in 33 (n = 33/167, 19.8 %) patients. aPL autoantibodies were non-criteria aPE IgG/IgM in most cases (n = 28/33, 84.8 %). aPS/PT IgG/IgM were found in 11 (n = 11/33, 33.3 %) cases and aCL or aß2GP1 IgG/IgM in 4 (n = 4/33, 12.1 %). Multivariable logistic regression showed that aPL autoantibodies were mostly associated with UFD (OR 4.37 [1.72-11.20], p = 0.002), PE ≤ 34th week of gestation (3.22 [0.86-11.90], p = 0.070) and chronic deciduitis (8.03 [0.89-67.2], p = 0.060) DISCUSSION: The frequency of aPL autoantibodies, mostly aPE, is high in patients with late pregnancy morbidity and may qualify obstetrical APS.

Pre-pregnancy obesity among immigrant and non-immigrant women in Norway: Prevalence, trends, and subgroup variations.

INTRODUCTION: This study assessed prevalence and time trends of pre-pregnancy obesity in immigrant and non-immigrant women in Norway and explored the impact of immigrants' length of residence on pre-pregnancy obesity prevalence. MATERIAL AND METHODS: Observational data from the Medical Birth Registry of Norway and Statistics Norway for the years 2016-2021 were analyzed. Immigrants were categorized by their country of birth and further grouped into seven super regions defined by the Global Burden of Disease study. Pre-pregnancy obesity was defined as a body mass index ≥30.0 kg/m2, with exceptions for certain Asian subgroups (≥27.5 kg/m2). Statistical analysis involved linear regressions for trend analyses and log-binomial regressions for prevalence ratios (PRs). RESULTS: Among 275 609 pregnancies, 29.6% (N = 81 715) were to immigrant women. Overall, 13.6% were classified with pre-pregnancy obesity: 11.7% among immigrants and 14.4% among non-immigrants. Obesity prevalence increased in both immigrants and non-immigrants during the study period, with an average yearly increase of 0.62% (95% confidence interval [CI]: 0.55, 0.70). Obesity prevalence was especially high in women from Pakistan, Chile, Somalia, Congo, Nigeria, Ghana, Sri Lanka, and India (20.3%-26.9%). Immigrant women from "Sub-Saharan Africa" showed a strong association between longer residence length and higher obesity prevalence (≥11 years (23.1%) vs. <1 year (7.2%); adjusted PR = 2.40; 95% CI: 1.65-3.48), particularly in women from Kenya, Eritrea, and Congo. CONCLUSIONS: Prevalence of maternal pre-pregnancy obesity increased in both immigrant and non-immigrant women from 2016 to 2021. Several immigrant subgroups displayed a considerably elevated obesity prevalence, placing them at high risk for adverse obesity-related pregnancy outcomes. Particular attention should be directed towards women from "Sub-Saharan Africa", as their obesity prevalence more than doubled with longer residence.

Monkeypox infection and pregnancy in lower and middle-income countries: Precautions & recommendations.

Monkeypox (MPX), an orthopoxviral disease endemic in Africa, is now a public health emergency of international concern (PHEIC) as declared by the World Health Organization in July 2023. Although it is generally mild, the overall case fatality rate was reported to be 3%, and the basic reproduction number (R0) is > 1 in men who have sex with men (MSM, i.e., Portugal (1.4), the United Kingdom (1.6), and Spain (1.8)). However, R0 is < 1 in other settings. In concordance with the smallpox virus, it is also expected to increase the risk of adverse outcomes for both the mother and the fetus. The outcomes of the disease in an immunocompromised state of pregnancy are scary, showing high mortality and morbidity of both mother and fetus, with up to a 75% risk of fetal side effects and a 25% risk of severe maternal diseases. Therefore, it warrants timely diagnosis and intervention. The reverse transcription polymerase chain reaction (RT PCR) test is the standard approach to diagnosis. We summarized the recent findings of MPX on pregnancy, and the associated risk factors. We also give recommendations for active fetal surveillance, perinatal care, and good reporting to improve outcomes. The available vaccines have shown promise for primary disease prevention.

Preeclampsia and neonatal outcomes in pregnancies with maternal congenital heart disease: A nationwide cohort study from Norway.

INTRODUCTION: The prevalence of congenital heart disease (CHD) among women of reproductive age is rising. We aimed to investigate the risk of preeclampsia and adverse neonatal outcomes in pregnancies of mothers with CHD compared to pregnancies of mothers without heart disease. MATERIAL AND METHODS: In a nationwide cohort of pregnancies in Norway 1994-2014, we retrieved information on maternal heart disease, the course of pregnancy, and neonatal outcomes from national registries. Comparing pregnancies with maternal CHD to pregnancies without maternal heart disease, we used Cox regression to estimate the adjusted hazard ratio (aHR) for preeclampsia and log-binomial regression to estimate the adjusted risk ratio (aRR) for adverse neonatal outcomes. The estimates were adjusted for maternal age and year of childbirth and presented with 95% confidence intervals (CIs). RESULTS: Among 1 218 452 pregnancies, 2425 had mild maternal CHD, and 603 had moderate/severe CHD. Compared to pregnancies without maternal heart disease, the risk of preeclampsia was increased in pregnancies with mild and moderate/severe maternal CHD (aHR1.37, 95% CI 1.14-1.65 and aHR 1.62, 95% CI 1.13-2.32). The risk of preterm birth was increased in pregnancies with mild maternal CHD (aRR 1.33, 95% CI 1.15-1.54) and further increased with moderate/severe CHD (aRR 2.49, 95% CI 2.03-3.07). Maternal CHD was associated with elevated risks of both spontaneous and iatrogenic preterm birth. The risk of infants small-for-gestational-age was slightly increased with mild maternal CHD (aRR 1.12, 95% CI 1.00-1.26) and increased with moderate/severe CHD (aRR 1.63, 95% CI 1.36-1.95). The prevalence of stillbirth was 3.9 per 1000 pregnancies without maternal heart disease, 5.6 per 1000 with mild maternal CHD, and 6.8 per 1000 with moderate/severe maternal CHD. Still, there were too few cases to report a significant difference. There were no maternal deaths in women with CHD. CONCLUSIONS: Moderate/severe maternal CHD in pregnancy was associated with increased risks of preeclampsia, preterm birth, and infants small-for-gestational-age. Mild maternal CHD was associated with less increased risks. For women with moderate/severe CHD, their risk of preeclampsia and adverse neonatal outcomes should be evaluated together with their cardiac risk in pregnancy, and follow-up in pregnancy should be ascertained.

Outpatient versus inpatient management of preterm prelabor rupture of membranes: A systematic review and meta-analysis.

INTRODUCTION: To compare neonatal, obstetrical, and maternal outcomes associated with outpatient versus inpatient management of pregnancies with preterm prelabor rupture of membranes (PPROM). MATERIAL AND METHODS: A search of MEDLINE, EMBASE, the Cochrane Database and Central Register from January 1, 1990 to July 31, 2023 identified randomized controlled trials (RCTs) and cohort studies comparing outpatient with inpatient management for pregnant persons diagnosed with PPROM before 37 weeks' gestation. No language restriction was applied. We applied a random effects model for meta-analysis. Trustworthiness was assessed using recently published guidance and Risk of bias using the RoB 2.0 tool for RCTs and ROBINS-I tool for cohort studies. The Grading of Recommendations, Assessment, Development, and Evaluations (GRADE) approach was used to assess the certainty of evidence (COE). Outcomes of interest included perinatal mortality, neonatal morbidities, latency and gestational age at delivery, and maternal morbidities. RCTs and cohort studies were analyzed separately. This study was registered in the International Prospective Register of Systematic Reviewsr: CRD42022295275. RESULTS: From 2825 records, two RCTs and 10 cohort studies involving 1876 patients were included in the review and meta-analysis. Outpatient management protocols varied but generally included brief initial hospitalization, strict eligibility criteria, and surveillance with laboratory and ultrasound investigations. Outpatient management showed lower rates of neonatal respiratory distress syndrome (cohort: RR 0.63 [0.52-0.77, very low COE]), longer latency to delivery (RCT: MD 7.43 days [1.14-13.72 days, moderate COE], cohort: MD 8.78 days [2.29-15.26 days, low COE]), higher gestational age at birth (cohort: MD 7.70 days [2.02-13.38 days, low COE]), lower rates of Apgar scores <7 at 5 min of life (cohort: RR 0.66 [0.50-0.89, very low COE]), and lower rates of histological chorioamnionitis (cohort: RR 0.74 [0.62-0.89, low COE]) without increased risks of adverse neonatal, obstetrical, or maternal outcomes. CONCLUSIONS: Meta-analysis of data from RCTs and cohort studies with very low-to-moderate certainty of evidence indicates that further high-quality research is needed to evaluate the safety and potential benefits of outpatient management for selected PPROM cases, given the moderate-to-high risk of bias in the included studies.

A Comparison of Neonatal Outcomes Between Obese and Nonobese Women With Preterm Prelabor Rupture of Membranes.

Introduction Preterm prelabor rupture of membrane (PPROM) contributes to increasing rates of preterm birth, causing greater health risks for newborns. While the mechanisms driving PPROM are not well understood, one hypothesis is that it is due to systemic inflammation, which can be caused by obesity defined as a BMI [Formula: see text]30 kg/m2. The specific aim of the study was to compare neonatal outcomes after PPROM between patients who were obese vs not obese in early pregnancy at a tertiary medical center serving an Appalachian population. Methods An observational, descriptive retrospective review was conducted of the medical records of patients who were diagnosed with PPROM from January 2017 through December 2020. Patients with a single gestation at the time of PPROM without evidence of clinical infection requiring immediate delivery were included. Maternal characteristics, latency management, and birth outcomes were compared between obese ([Formula: see text]30 BMI) and non-obese (<30 BMI) patients. Results Of the 214 women in the study, 129 (60.3%) were obese pre-pregnancy and 85 (39.7%) were not. Most PPROM occurred between 32 and 36 weeks of gestation (145 patients, 67.8%), with 19.2% occurring at 26-31 weeks (41 patients), and 13.2% at <26 weeks of gestation (28 patients). Latency, defined as the days between PPROM and delivery, ranged from 0 to 80 days with a mean of 4.9 + 10.9 days. At least one day of latency was achieved for most patients (144/214; 67.3%). When outcomes were compared between obese and nonobese patients, the obese patients experienced significantly more complications (10.1% vs 2.4%; p=0.031), which were accompanied by greater neonatal morbidity 67 of 129 ((51.9%) vs 30 of 85 (35.3%); p=0.018). Obese women had greater odds that their newborns would experience neonatal morbidity than nonobese women (odds ratio, 1.98; 95% confidence interval, 1.1-3.5). Conclusion This study of Appalachian women found that pre-pregnancy BMI [Formula: see text]30 increased the risk of complications and neonatal morbidity after PPROM. To improve birth outcomes, healthcare workers and policymakers must work together to decrease rates of obesity in Appalachian women at or near childbearing age.

Antithrombin testing and treatment in pregnancy: Their real-world relationship to clinical outcomes.

BACKGROUND: Antithrombin (AT) deficiency is a severe thrombophilia associated with increased rates of maternal morbidity, mortality, and greater healthcare resource utilization during pregnancy and postpartum. METHODS: Two large U.S. healthcare databases were queried for women aged 15-44 with delivery-related encounters: Cerner Real-World Data (CRWD, 01/01/2000-12/31/2021) and Premier Healthcare Database (PHD, 01/01/2016-01/01/2019). Individuals receiving cardiopulmonary bypass were excluded. Three cohorts were created: 1) Individuals who had AT levels tested any time between 9-months pre- through 3-months post-delivery (CRWD Test Cohort); 2) individuals prescribed AT concentrate (ATc) within 1-year pre- or 1-year post-delivery in CRWD (CRWD Medication Cohort); and 3) the same criteria as 2) applied to PHD (PHD Medication Cohort). RESULTS: There were 5411 individuals in the CRWD Test Cohort, 13 in the CRWD Medication Cohort and 38 in the PHD Medication Cohort. Demographic and baseline clinical characteristics were similar across cohorts. AT level testing occurred pre-delivery in 47.9 % of the CRWD Test Cohort and 23.1 % of the CRWD Medication Cohort. ATc was administered during the delivery hospitalization to 0.1 %, 23.1 % and 50.0 % of the CRWD Test, CRWD Medication, and PHD Medication Cohorts, respectively. Across cohorts, 5.4-7.9 % of individuals experienced thrombosis during the delivery-related encounter. Mean (SD) total costs for delivery through 1-year post-delivery were $190,894 ($276,893) with $123,763 ($177,122) of total costs related to abnormal coagulation. CONCLUSION: Opportunities exist to enhance the care of pregnant individuals with low AT levels throughout pregnancy, aiming for optimal maternal outcomes.

Midwives' and registered nurses' role and scope of practice in acute early pregnancy care settings in Australia: A qualitative descriptive study.

PROBLEM: There is little documented evidence regarding the practice of midwives providing care for women with acute concerns in early pregnancy (< 20 weeks) in Australia. BACKGROUND: Women can experience unexpected complications at any gestation of pregnancy and may seek acute care in an emergency or gynaecology service, usually staffed by registered nurses (RNs). They may not receive care from specialised pregnancy clinicians, including midwives. The role and scope of practice of midwives working in acute early pregnancy settings in Australia has not been previously reported. This study provides an opportunity to document practice in an area of pregnancy care not often visible within maternity services in Australia. RESEARCH AIM: To describe midwives' and RNs perceptions, perspectives and experiences of role and scope of practice in acute early pregnancy care provision in Australia. METHODS: A qualitative descriptive approach was adopted. Midwives and RNs with acute early pregnancy knowledge and experience were recruited. Semi-structured interviews were conducted, and data analysed using inductive thematic analysis. FINDINGS: Fifteen participants were interviewed. Three themes were constructed from interview data: Personal and Professional Influences; Being There for Women; The Impact of Setting. DISCUSSION: Findings reinforce the lack of clarity around how midwives' scope is enabled in traditional acute early pregnancy care. Setting of care has influenced practice and seen a barrier for midwives who don't hold nursing registration from fulfilling professional scope. Results provide novel benchmarking evidence regarding a largely hidden area of midwifery, signposting areas for reform within education, policy and health service sectors.

Changes in adverse obstetrical and neonatal outcomes over time in American women with polycystic ovary syndrome: an 11-year study of a population database.

PURPOSE: To determine whether the prevalence in American demographic and resultant adverse obstetric outcomes changed in women with polycystic ovary syndrome between the years of 2004-2014 inclusively, based on data derived from the Healthcare Cost and Utilization Project Nationwide Inpatient Sample (HCUP-NIS) database. METHODS: This is a retrospective population-based study using data derived from the HCUP-NIS database from the years of 2004-2014, inclusively. Within this group, all pregnancies to women with PCOS were identified and separated by year, creating 11 groups. RESULTS: Risk factors including non-Caucasian race, lower socioeconomic status, and rates of obesity and thyroid disease increased over time. The rates of gestational diabetes mellitus demonstrated a slight decrease, (21.3% in 2004 to 18.0% in 2014, P = 0.01). The number of women with preterm premature rupture of membranes decreased from 3.0% in 2004 to 2.0% in 2014 (P = 0.04). Rates of preterm delivery decreased from 14.8% in 2004 to 9.8% in 2014 (P < 0.001). Rates of cesarean section decreased from 57.3% in 2004 to 45.7% in 2014 (P < 0.001), while rates of spontaneous vaginal delivery increased from 37.4% in 2004 to 50.1% in 2014 (P < 0.001). The rate of wound complications decreased from 2.1% in 2004 to 0.4% in 2014 (P < 0.001). However, the rate of congenital anomalies increased from 0.5% in 2004 to 1.2% in 2014 (P = 0.001). CONCLUSIONS: In spite of increases in demographic risk factors associated with increased pregnancy complications, we hypothesize that the interventions made to minimize the risks of cesarean section and manage metabolic complications in women with PCOS during the period of study have resulted in improved pregnancy outcomes during the period of study.

Obstetric and perinatal outcomes in women with cerebrovascular accident vs. transient ischemic attack: an evaluation of a population database.

PURPOSE: Cerebrovascular accidents (CVAs) and transient ischemic attacks (TIAs) are uncommon neurologic events in women of childbearing age. We aimed to compare pregnancy, delivery, and neonatal outcomes between women who suffered from a CVA and those who experienced a TIA. METHODS: A retrospective population-based cohort study was performed using the Healthcare Cost and Utilization Project, Nationwide Inpatient Sample. Included were all pregnant women who delivered or had a maternal death in the US between 2004 and 2014. We compared women with an ICD-9 diagnosis of a CVA before or during pregnancy to those diagnosed with a TIA before, during the pregnancy, or during the delivery admission. Pregnancy and perinatal outcomes were compared between the two groups, using multivariate logistic regression to control for confounders. RESULTS: Among 9,096,788 women in the database, 898 met the inclusion criteria. Of them, 706 women (7.7/100,000) had a CVA diagnosis, and 192 (2.1/100,000) had a TIA diagnosis. Women with a CVA, compared to those with a TIA, had a higher rate of pregnancy-induced hypertension (aOR 3.82,95%CI 2.14-6.81, p < 0.001); preeclampsia (aOR 2.6,95%CI 1.3-5.2, p = 0.007), eclampsia (aOR 13.78,95% CI 1.84-103.41, p < 0.001); postpartum hemorrhage (aOR 4.52,95%CI 1.31-15.56, p = 0.017), blood transfusion (aOR 5.57,95%CI 1.65-18.72, p = 0.006), and maternal death (54 vs. 0 cases, 7.6% vs. 0%), with comparable neonatal outcomes. CONCLUSION: Women diagnosed with a CVA before or during pregnancy had a higher incidence of myriad maternal complications, including hypertensive disorders of pregnancy, postpartum hemorrhage, and death, compared to women with a TIA diagnosis, with comparable neonatal outcomes, stressing the different prognoses of these two conditions, and the importance of these patients' diligent follow-up and care.

Vaginal Microbiome and Pregnancy Complications: A Review.

Background/Objectives: There are indications that the microbial composition of the maternal mucosal surfaces is associated with adverse events during pregnancy. The aim of this review is to investigate the link between vaginal microbiome alterations and gestational complication risk. Methods: This comprehensive literature review was performed using Medline and Scopus databases. The following search algorithm was used, "Pregnancy Complications" [Mesh] AND (Vagin*), and after the literature screening, 44 studies were included in the final review. Results: The studies that were included investigated the association between vaginal microbial composition and preterm birth, miscarriage, preeclampsia, ectopic pregnancy, gestational diabetes mellitus, chorioamnionitis, and preterm premature rupture of membranes. In most of the studies, it was well established that increased microbial diversity is associated with these conditions. Also, the depletion of Lactobacillus species is linked to most of the gestational complications, while the increased relative abundance and especially Lactobacillus crispatus may exert a protective effect in favor of the pregnant woman. Several pathogenic taxa including Gardnerella, Prevotella, Sneathia, Bacterial Vaginosis-Associated Bacteria-2, Atopobium, and Megasphera seem to be correlated to higher maternal morbidity. Conclusions: Vaginal microbiome aberrations seem to have an association with pregnancy-related adverse events, but more high-quality homogenous studies are necessary to reliably verify this link.

Clinical implications of a Couvelaire uterus with placental abruption: A retrospective study.

OBJECTIVE: This study aimed to clarify the maternal and neonatal outcomes based on the presence or absence of a Couvelaire uterus with placental abruption. METHODS: This single-center retrospective study was conducted at a tertiary perinatal center in Japan, including patients diagnosed with acute placental abruption who delivered live births via cesarean section between 2016 and 2023. Patients were divided into two groups based on the presence or absence of a Couvelaire uterus during surgery: the Couvelaire and normal uterus groups. Maternal and neonatal outcomes were assessed. RESULTS: This study included 76 patients: 24 in the Couvelaire group and 52 in the normal uterus group. No patients underwent hysterectomies. The Couvelaire group had significantly higher intraoperative blood loss (median 1152 vs 948 g, P = 0.010), blood transfusion rates (58% vs 31%, P = 0.022), fibrinogen administration rates (38% vs 13%, P = 0.038), intensive care unit/high care unit admission rates (29% vs 7.7%, P = 0.013), and disseminated intravascular coagulation complication rates (25% vs 7.7%, P = 0.038). There were no differences in birth weight, gestational age (median 2387 vs 2065 g, P = 0.082), Apgar score <4 at 5 min (4.2% vs 3.9%, P = 0.95), umbilical artery blood pH <7.1 (25% vs 22%, P = 0.82), and neonatal death (4.2% vs 1.9%, P = 0.57). CONCLUSION: A Couvelaire uterus indicated adverse maternal outcomes but not neonatal ones. Its presence necessitates preparation for blood transfusions and/or intensive patient follow-up.

Overcoming Recurrent Miscarriages in a 35-Year-Old Female With Thrombophilia.

Thrombophilias, which include both hereditary and acquired illnesses, are a range of abnormalities that make persons more prone to developing thromboembolism. Thrombophilic conditions carry significant dangers during pregnancy, such as miscarriage in early pregnancy, intrauterine growth restriction, abruptio placenta, and preeclampsia. According to compiled statistics, an average of 15%-20% of pregnancies end in miscarriage. While the risk of miscarriage in a first pregnancy is 11%, this risk increases to between 13% and 17% in subsequent pregnancies, and after the third miscarriage, it reaches 38%. This research article presents a detailed case report that focuses on a patient who has experienced three previous failed pregnancies. The patient's genetic analysis indicates that she has two copies of a mutated version of the methylenetetrahydrofolate reductase (MTHFR) gene (Ala222Val) and a variation in the plasminogen activator inhibitor 1 (PAI-1) gene known as 4G/5G. In addition, an evaluation of immunological characteristics revealed increased amounts of natural killer (NK) cells with enhanced activity, along with the identification of embryotoxins in a blood test that suppress embryotoxicity in a blood test, assisted by DNA isolation and real-time polymerase chain reaction (PCR) DNA analysis.

Pregnancy complications and birth outcomes in women with polycystic ovary syndrome undergoing frozen embryo transfer.

OBJECTIVE: To determine whether polycystic ovary syndrome (PCOS) increases adverse pregnancy and birth outcomes in women undergoing frozen embryo transfer (FET). DESIGN: Retrospective cohort study. The PCOS group was matched 1:2 with the control group population using propensity score matching (PSM). PATIENTS: During an 8-year period, 2,955 patients aged 20 to 40 years who underwent FET and delivered between January 2015 and December 2022 at the Reproductive Medical Center of Ruijin Hospital were evaluated for adverse pregnancy outcomes. INTERVENTION(S): None. MAIN OUTCOME MEASURES: All patients were assessed for specific pregnancy complications and birth outcomes, with a sub-group analysis conducted to compare PCOS patients with and without hyperandrogenism. RESULTS: Women with PCOS demonstrated higher rates of gestational diabetes mellitus (24.9% vs. 16.4%; relative risk (RR) 1.51 [95% confidence interval (CI): 1.26-1.82]; P <0.001), gestational hypertension (12.2% vs. 8.9%; RR 1.37 [95% CI: 1.05-1.80]; P = 0.022), preterm prelabour rupture of membranes (7.0% vs. 3.6%; RR 1.92 [95% CI: 1.29-2.86]; P = 0.001), cervical length shortening (1.8% vs. 0.4%; RR 8.39 [95% CI: 1.56-12.49]; P = 0.002), large-for-gestational age (17.4% vs. 13.7%; RR 1.27 [95% CI: 1.02-1.57]; P = 0.032), and low birth weight (19.9% vs. 16.0%; RR 1.25 [95% CI: 1.02-1.52]; P = 0.030) in overall PSM analysis. Newborns of patients with PCOS had a higher risk of preterm birth < 37 weeks (10.5% vs. 6.6%; RR 1.59 [95% CI: 1.12-2.26]; P = 0.009) in singleton pregnancies. PCOS patients with hyperandrogenism showed a higher incidence of cervical length shortening (5.5% vs. 0.5%; adjusted odds ratio (AOR) 15.62 [95% CI: 2.25-108.48]; P = 0.005) compared to those without, after adjusting for relevant confounders. CONCLUSION: PCOS increases the incidence of adverse pregnancy outcomes after FET cycles. Our study suggests women with PCOS may warrant further monitoring and additional counseling before and during pregnancy.
