First trimester plasma PER- AND Polyfluoroalkyl Substances (PFAS) and blood pressure trajectories across the second and third trimesters of pregnanacy.

BACKGROUND: Evidence suggests that exposure to per- and polyfluoroalkyl substances (PFAS) increases risk of high blood pressure (BP) during pregnancy. Prior studies did not examine associations with BP trajectory parameters (i.e., overall magnitude and velocity) during pregnancy, which is linked to adverse pregnancy outcomes. OBJECTIVES: To estimate associations of multiple plasma PFAS in early pregnancy with BP trajectory parameters across the second and third trimesters. To assess potential effect modification by maternal age and parity. METHODS: In 1297 individuals, we quantified six PFAS in plasma collected during early pregnancy (median gestational age: 9.4 weeks). We abstracted from medical records systolic BP (SBP) and diastolic BP (DBP) measurements, recorded from 12 weeks gestation until delivery. BP trajectory parameters were estimated via Super Imposition by Translation and Rotation modeling. Subsequently, Bayesian Kernel Machine Regression (BKMR) was employed to estimate individual and joint associations of PFAS concentrations with trajectory parameters - adjusting for maternal age, race/ethnicity, pre-pregnancy body mass index, income, parity, smoking status, and seafood intake. We evaluated effect modification by age at enrollment and parity. RESULTS: We collected a median of 13 BP measurements per participant. In BKMR, higher concentration of perfluorooctane sulfonate (PFOS) was independently associated with higher magnitude of overall SBP and DBP trajectories (i.e., upward shift of trajectories) and faster SBP trajectory velocity, holding all other PFAS at their medians. In stratified BKMR analyses, participants with ≥ 1 live birth had more pronounced positive associations between PFOS and SBP velocity, DBP magnitude, and DBP velocity - compared to nulliparous participants. We did not observe significant associations between concentrations of the overall PFAS mixture and either magnitude or velocity of the BP trajectories. CONCLUSION: Early pregnancy plasma PFOS concentrations were associated with altered BP trajectory in pregnancy, which may impact future cardiovascular health of the mother.

Impact of in utero tobacco exposure on fetal growth: Amount of exposure and second trimester fetal growth measurements.

BACKGROUND: Research reveals small and inconsistent findings linking prenatal tobacco exposure and early fetal growth, but failure to consider confounding and amount of exposure many explain inconsistencies. GOAL: To examine whether fetal growth effects following exposure to tobacco are evident in the second trimester, specific to certain growth parameters, and dose dependent. METHODS: Participants were pregnant women (64 smokers, 100 controls) with no other drug use. Available data included background/medical information and ultrasound measurements coded as percentiles. RESULTS: Controlling for background differences, 10+ cig/day predicted a 10+ percentile point reduction in estimated fetal weight, femur length, head circumference, and biparietal diameter compared to non-exposed controls. Exposure to <10 cig/day predicted significant reduction in only biparietal diameter. Exposure was unrelated to abdominal circumference. CONCLUSIONS: Results demonstrate utility of considering amount of exposure when examining/quantifying fetal growth effects, and suggest even reduction in early pregnancy smoking may positively benefit aspects of fetal development.

Physical activity during pregnancy and the risk of gestational diabetes mellitus: a systematic review and dose-response meta-analysis.

BACKGROUND: Previous research has indicated the inverse association between physical activity (PA) and gestational diabetes mellitus (GDM). However, the dose-response relationship currently remains undetermined. This study aims to explore the dose-response relationship between PA during the first and second trimesters of pregnancy and GDM risk. METHODS: Studies on the relationship between PA during pregnancy and GDM risk published before April 25, 2023, were searched for in six databases. According to the inclusion and exclusion criteria, all literature was screened for eligibility. The Newcastle-Ottawa Scale (NOS) was used to assess risk of bias. Publication bias was examined using funnel plots, Begg's and Egger's tests, as well as trim-and-fill analysis. We harmonized exposure estimates of PA during pregnancy to the common unit of the metabolic equivalent of task (MET)-h/week. Restricted cubic splines were used to model the dose-response relationship. The criteria from the World Cancer Research Fund were used to assess the certainty of evidence across outcomes. All analyses were performed using Stata 15.1. RESULTS: The results indicated that in contrast with the lowest level of PA, promoting the highest PA level lowers the risk of GDM by 36% (RR = 0.64, 95%CI: 0.53 ~ 0.78). We found a curvilinear dose-response association between PA during the first trimester and incident GDM (Pnonlinearity = 0.012). Compared to inactive pregnant women, for those who achieved the guidelines-suggested minimum level (10 MET-h/week) of PA during the first trimester, the GDM risk was decreased by 13% (RR = 0.87, 95%CI: 0.79 ~ 0.96). A linear relationship was found between PA during the second trimester and the GDM risk (Pnonlinearity = 0.276). The results with a restricted cubic spline model suggested that pregnant women who accumulate 10 MET-h/week have a 1% reduced risk of GDM compared to completely inactive individuals. Twice (20 MET-h/week) or a higher amount of PA (50 MET-h/week) contributed to further reductions in GDM risk. CONCLUSION: There is a dose-response relationship between higher levels of PA in both the first and second trimesters and reduced risk of GDM; the relationship is stronger in the first trimester. Increasing PA during pregnancy can prevent the development of GDM. PROSPERO REGISTRATION NUMBER: CRD42023420564.

A case report of vaginal delivery in the second trimester of severe uterine prolapse complicated with cervical incarceration.

BACKGROUND: Uterine prolapse is a rare complication of pregnancy, and there is still no consensus on the choice of delivery method. METHODS: The patient's reproductive history included an abortion and eutocic delivery of a girl weighing 3200 g; the current pregnancy was the third pregnancy. Her cervical region was outside the vaginal opening and was red in color, with evident enlargement (6 × 4 cm) and a broken surface. The cervical area also showed white discharge. According to her Transvaginal ultrasonography revealed a fetus in the uterine cavity at approximately 19 weeks of gestation. Gynecological examination revealed prolapse of both the anterior and posterior vaginal walls. Evaluation of the pelvic organ prolapse-Q scores showed that the patient had uterine prolapse at stage IV. RESULTS: Vaginal delivery was performed smoothly after oral administration mifepristone and misoprostol tablets for a few days, obtaining a dead female fetus in cephalic, 25 cm in length. The cervix of the pregnant woman did not prolapse during the delivery. CONCLUSION: For pregnancy with uterine prolapse and cervical incarceration, transvaginal delivery is a potential treatment option. Maintenance of cervical retraction and oral mifepristone administration with misoprostol tablets is crucial during this delivery. This treatment can minimize the risk of cervical lacerations and uterine rupture, helping surgeons to complete the operation successfully.

Adjuvant misoprostol or mifepristone for cervical preparation with osmotic dilators before dilation and evacuation.

OBJECTIVES: This study aimed to compare effectiveness and safety of cervical preparation with osmotic dilators plus same-day misoprostol or overnight mifepristone prior to dilation and evacuation (D&E). STUDY DESIGN: We conducted a retrospective cohort analysis of 664 patients initiating abortion between 18 and 22 weeks at an ambulatory health center. We abstracted medical record data from two consecutive 12-month periods in 2017 to 2019. All patients received overnight dilators plus: 600 mcg buccal misoprostol 90 minutes before D&E (period 1); 200 mg oral mifepristone at time of dilators (period 2). Our primary outcome was procedure time. We report frequency of patients experiencing any acute complication, defined as unplanned procedure (i.e., reaspiration, cervical laceration repair, uterine balloon tamponade) or hospital transfer and bleeding complications. RESULTS: We observed higher mean procedure time in the mifepristone group (9.7 ± 5.3 minutes vs 7.9 ± 4.4, p = 0.004). After adjusting for race, ethnicity, insurance, body mass index, parity, prior cesarean, prior uterine surgery, gestational age, provider, trainee participation, and long-acting reversible contraception initiation, the difference remained statistically significant (relative change 1.09, 95% CI 1.01, 1.17) but failed to reach our threshold for clinical significance. The use of additional misoprostol was more common in the mifepristone group, but the use of an additional set of dilators was not different between groups. Acute complications occurred at a frequency of 4.1% in misoprostol group and 4.3% in mifepristone group (p = 0.90). CONCLUSIONS: We found procedure time to be longer with adjunctive mifepristone compared to misoprostol; however, this difference is unlikely to be clinically meaningful. Furthermore, the frequency of acute complications was similar between groups. IMPLICATIONS: Overnight mifepristone at the time of cervical dilator placement is a safe and effective alternative to adjuvant same-day misoprostol for cervical preparation prior to D&E and may offer benefits for clinic flow and patient experience.

Plasma trimethylamine N-oxide metabolites in the second trimester predict the risk of hypertensive disorders of pregnancy: a nested case-control study.

The relationship between gut microbiota products trimethylamine oxide (TMAO) and related metabolites including betaine, choline and L-carnitine and hypertensive disorders of pregnancy (HDP) is unclear. In order to examine whether plasma TMAO and related metabolites predict the risk of HDP, a nested case-control study was conducted in Chinese women based on a prospective cohort including 9447 participants. 387 pairs of pregnant women (n = 774) were matched and their plasma TMAO, betaine, choline, and L-carnitine at 16-20 gestational weeks were measured by liquid chromatography-mass spectrometry. Odds ratio (OR) and the 95% confidence interval (95% CI) were calculated using the conditional logistic regression, to examine the association between TMAO metabolites and HDP. The findings showed that higher plasma betaine (≥24.94 µmol/L) was associated with a decreased risk of HDP and its subtype gestational hypertension (GH), with adjusted ORs of 0.404 (95% CI: 0.226-0.721) and 0.293 (95% CI: 0.134-0.642), respectively. Higher betaine/choline ratio (>2.64) was associated with a lower risk of HDP and its subtype preeclampsia or chronic hypertension with superimposed preeclampsia (PE/CH-PE), with adjusted ORs of 0.554 (95% CI: 0.354-0.866) and 0.226 (95% CI: 0.080-0.634). Moreover, compared with traditional factors (TFs) model, the TMAO metabolites+ TFs model had a higher predictive ability for PE/CH-PE (all indexes P values < 0.0001). Therefore, it suggests that the detection of plasma betaine and choline in the early second trimester of pregnancy can better assess the risk of HDP.

Maternal Iron and Vitamin D Status during the Second Trimester Is Associated with Third Trimester Depression Symptoms among Pregnant Participants in the APrON Cohort.

BACKGROUND: The maternal status of multiple micronutrients during pregnancy and postpartum and their potential associations with maternal health outcomes are largely undescribed. OBJECTIVES: This study aimed to examine associations between maternal iron and vitamin D status, individually and in combination, on depression symptoms in pregnant individuals. METHODS: The Alberta Pregnancy Outcomes and Nutrition cohort study included pregnant participants and their children from Calgary and Edmonton, Canada. Iron biomarkers (serum ferritin [SF], soluble transferrin receptor, and hepcidin) were measured via immunoassays and vitamin D [25-hydroxyvitamin D3 (25(OH)D3) and 3-epi-25-hydoxyvitamin D3 (3-epi-25(OH)D3)] metabolites were quantifed using liquid chromatography with tandem mass spectroscopy. Four categories of maternal iron and vitamin D status during the second trimester were conceptualized using concentrations of SF and total 25-hydoxyvitamin D [25(OH)D], respectively. Maternal Edinburgh Postnatal Depression Scale (EPDS) scores during the third trimester (n = 1920) and 3 mo postpartum (n = 1822) were obtained. RESULTS: Concentrations of maternal 25(OH)D3, 3-epi-25(OH)D3, and the ratio of both metabolites were significantly higher during the second trimester compared with their status at 3 mo postpartum. Higher second trimester maternal concentrations of SF (ß: -0.8; 95% confidence interval [CI]: -1.5, -0.01), hepcidin (ß: -0.5; 95% CI: -0.9, -0.2), and 25(OH)D3 (ß: -0.01; 95% CI: -0.02, -0.004) predicted lower maternal EPDS scores during the third trimester. Pregnant individuals with a low iron (SF <15 µg/L) and replete vitamin D (25(OH)D ≥75 nmol/L) (ß: 1.1; 95% CI: 0.03, 2.1) or low iron (SF <15 µg/L) and vitamin D (25(OH)D <75 nmol/L) (ß: 2.2; 95% CI: 0.3, 4.2) status during midpregnancy had higher third trimester EPDS scores compared with those that were replete in both micronutrients. CONCLUSIONS: A higher midpregnancy maternal iron and vitamin D status, independently or in combination, predicted fewer maternal depression symptoms in the third trimester. Concentrations of maternal 25(OH)D3 and 3-epi-25(OH)D3 may be lower in the postpartum period compared with midpregnancy.

Antibiotic treatment reduces the intensity of intraamniotic inflammation in pregnancies with idiopathic vaginal bleeding in the second trimester of pregnancy.

BACKGROUND: Idiopathic bleeding in the second trimester of pregnancy complicates <1% of all pregnancies. This pregnancy complication can be caused by alterations in local hemostasis in the decidua due to infection/inflammation in the choriodecidual niche. This condition is associated with intraamniotic inflammatory complications. Antibiotic therapy effectively reduces the intensity of intraamniotic inflammation in certain pregnancy pathologies. However, whether antibiotic administration can reduce the intensity of the intraamniotic inflammatory response or eradicate microorganisms in patients with idiopathic bleeding during the second trimester of pregnancy remains unclear. OBJECTIVE: This study primarily aimed to determine whether antimicrobial agents can reduce the magnitude of intraamniotic inflammation in patients with idiopathic bleeding in the second trimester of pregnancy by assessing the concentration of interleukin-6 in the amniotic fluid before and after 7 days of antibiotic treatment. The secondary aim was to determine whether treatment with a combination of antibiotics altered the microbial load of Ureaplasma species DNA in amniotic fluid. STUDY DESIGN: This retrospective cohort study included singleton-gestation patients with idiopathic bleeding between 15+0 and 27+6 weeks who underwent transabdominal amniocentesis at the time of admission. Follow-up amniocentesis was performed in a subset of patients unless abortion or delivery occurred earlier. Concentrations of interleukin-6 were measured in the amniotic fluid samples, and the presence of microbial invasion of the amniotic cavity was assessed using culture and molecular microbiological methods. Intraamniotic inflammation was defined as an interleukin-6 concentration ≥3000 pg/mL in the amniotic fluid samples. RESULTS: A total of 36 patients with idiopathic bleeding in the second trimester of pregnancy were included. All the patients underwent initial amniocentesis. Patients with intraamniotic inflammation (n=25) were treated using a combination of antibiotics consisting of intravenous ceftriaxone, intravenous metronidazole, and peroral clarithromycin. The patients without intraamniotic inflammation (n=11) were treated expectantly. In total, 25 patients delivered 7 days after admission. All patients with intraamniotic inflammation at the initial amniocentesis who delivered after 7 days underwent follow-up amniocentesis. Treatment with antibiotics decreased the interleukin-6 concentration in the amniotic fluid at follow-up amniocentesis compared with that at the initial amniocentesis in patients with intraamniotic inflammation (median [interquartile range]: 3457 pg/mL [2493-13,203] vs 19,812 pg/mL [11,973-34,518]; P=.0001). Amniotic fluid samples with Ureaplasma species DNA had a lower microbial load at the time of follow-up amniocentesis compared with the initial amniocentesis (median [interquartile range]: 1.5×105 copies DNA/mL [1.3×105-1.7×105] vs 8.0×107 copies DNA/mL [6.7×106-1.6×108]; P=.02). CONCLUSION: Antibiotic therapy was associated with reduced intraamniotic inflammation in patients with idiopathic bleeding in the second trimester complicated by intraamniotic inflammation. Moreover, antibiotic treatment has been associated with a reduction in the microbial load of Ureaplasma species DNA in the amniotic fluid.

A pragmatic evaluation of the implementation and acceptance of a universal second trimester cervical length screening program in an un-selected population.

PURPOSE: To evaluate patients' acceptance of a universal transvaginal ultrasound cervical length (CL) screening program and the feasibility of initiating treatment with progesterone in a clinical setting in women found to have a short cervix. METHODS: An observational, pragmatic cohort study was conducted at one tertiary care facility from 2012-2015, involving eligible women with singleton pregnancies who accepted and underwent second-trimester CL screening. The primary outcomes were the percentage of women who were eligible and accepting of screening, compliance with progesterone treatment, and the screening value of TVCL in predicting SPTB. Secondary outcomes were the number of women who received progesterone treatment and the rates of SPTB. RESULTS: Overall cervical length screening acceptance rate was found to be 82.5%. Of the 797 women that underwent screening, 21 women (2.6%) had a TVCL < 25 mm, of whom nine had a TVCL < 20.0 mm. Nineteen of the 21 women with a TVCL < 25 mm were treated with progesterone, with a 94.7% compliance rate. Delivery outcomes were obtained for 767 women. Of those with a TVCL < 25 mm, there was a 35% rate of SPTB as opposed to a 6.3% SPTB rate in those with TVCL > 25 mm. The negative predictive value for SPTB with a TVCL 25 mm or greater was 94.0%. CONCLUSION: Universal cervical length screening was successfully implemented in 82.5% of the patient population with a high compliance rate with progesterone treatment. Furthermore, there was a higher rate of SPTB in those with a shorter cervix. Based on our outcomes obtained in an observational and pragmatic manner, we showed that incorporating second trimester transvaginal cervical length screening into routine clinical practice is readily accepted and, with the addition of vaginal progesterone treatment, may reduce the rate of prematurity.

Misoprostol and mid trimester termination of pregnancy in patients with two previous scars and more at Elwiya Maternity Teaching Hospital / Misoprostol e interrupção da gravidez no meio do trimestre em pacientes com duas cicatrizes anteriores e mais no Elwiya Maternity Teaching Hospital

Abstract Objectives: to determine efficiency and safety of three misoprostol regimens for 2nd trimester pregnancy termination in individuals with two or more cesarean section scars. Methods: a cross-sectional study included 100 pregnant ladies at 13th-26th weeks gestation with previous two cesarean sections (CSs) who were scheduled for pregnancy termination using misoprostol. Patients were conveniently assigned to 100µg/3h, 200µg/3h or 400 µg/3h regimens. Primary outcome was time to abortion, secondary outcomes were side effect and complications. Results: a significant association was found between number previous CSs and longer time to abortion (p=0.01). A highly significant association was identified between earlier gestational age and longer time to abortion (p<0.001). Lower side effects and complications were associated with 200 µg misoprostol every 3 hours of (p<0.001). Incomplete abortion was the most frequent recorded complication for the successive doses of misoprostol. Conclusions: misoprostol is an effective drug at low doses for pregnancy termination in women with prior two or more caesarean sections. However, its safety needs monitoring of the patient in the hospital to decrease morbidity and mortality behind its use.

Resumo Objetivos: determinar a eficiência e segurança de três regimes de misoprostol para interrupção da gravidez no segundo trimestre em indivíduos com duas ou mais cicatrizes de cesariana. Métodos: um estudo transversal incluiu 100 gestantes entre 13ª e 26ª semanas de gestação com duas cesarianas (CEs) anteriores que foram agendadas para interrupção da gravidez com uso de misoprostol. Os pacientes foram convenientemente designados para regimes de 100 µg/3 horas, 200 µg/3 horas ou 400 µg/3 horas. O desfecho primário foi o tempo para o aborto, os desfechos secundários foram efeitos colaterais e complicações. Resultados: foi encontrada associação significativa entre o número de cesáreas anteriores e o maior tempo até o aborto (p=0,01). Foi identificada associação altamente significativa entre idade gestacional mais precoce e maior tempo para abortar (p<0,001). Menores efeitos colaterais e complicações foram associados com 200 µg de misoprostol a cada 3 horas (p<0,001). O aborto incompleto foi a complicação mais frequente registrada para as doses sucessivas de misoprostol. Conclusões: o misoprostol é um medicamento eficaz em doses baixas para interrupção da gravidez em mulheres com duas ou mais cesarianas anteriores. Porém, sua segurança necessita de monitoramento do paciente no hospital para diminuir a morbimortalidade por trás de seu uso.

Diagnosis of thanatophoric dysplasia using clinical exome screening.

Bone dysplasias are a broad, heterogeneous group of diseases. Thanatophoric dysplasia is a rare bone dysplasia, but it is the most common lethal skeletal dysplasias. The major role in diagnostics plays a high-quality ultrasound examination in the 2nd trimester and the latest methods of genetic testing, including clinical exome testing. Knowing the correct diagnosis is crucial for the future of the fetus and the couple.

Medical abortion in the second trimester - an update.

The safety and efficacy of medical abortion in the second trimester is provider independent and may therefore offer advantages over surgical second trimester abortion in certain settings. Due to bleeding risk, medical abortions in the second trimester are still mostly performed in a clinic or hospital setting. The most effective regimen for abortion includes pretreatment with oral mifepristone and following doses of misoprostol. An alternative is misoprostol only which should only be used when mifepristone is not available. The optimal dosing of prostaglandin to achieve the highest efficacy with the lowest proportion of complications remains to be established. Complications are rare and serious adverse events uncommon but may include uterine rupture especially in women with a previous cesarean delivery or uterine surgery. Women having second trimester medical abortion are a diverse group with different indications for the abortion. All women should be offered pain relief and respectful care. Staff involved in second trimester medical abortion often find their work challenging. At the same time, staff indicate pride and a conviction of contributing to the 'greater good' for women and society. Staff involved in second trimester abortion should be offered guidance and support through the employer. Post abortion contraception should be offered to all women having second trimester medical abortions, including those who have the abortion due to fetal malformation. All methods of contraception can be started immediately after a second trimester medical abortion except for cycle based methods and diaphragms.

Is a sFlt-1/PlGF cutoff of 38 suitable to predict adverse outcomes in pregnancies with abnormal uterine artery Doppler velocimetry in the second trimester?

OBJECTIVE: To determine the optimal cutoff value for the soluble fms-like tyrosine kinase-1 (sFlt-1)/placental growth factor (PlGF) ratio to predict maternal and fetal adverse events in pregnancies with uterine artery Doppler scans results above the 95th percentile in the late second trimester. STUDY DESIGN: Retrospective, observational cohort study on 116 asyntomatic patients with abnormal uterine artery Doppler scans at gestational week 25. The sFlt-1/PlGF ratio was determined within the weeks 25 to 29 of gestation and ROC curve analysis performed. The diagnostic validity of different cutoff values to predict severe maternal and fetal complications, i.e. preeclampsia, fetal growth restriction, placental abruption, and fetal death, was analyzed. MAIN OUTCOME MEASURES: An ideal cutoff for sFlt-1/PlGF ratios in pregnancies with abnormal uterine artery Doppler in the second trimester. RESULTS: Applying a cutoff point of 38, the area under the ROC curve was 0.89, generally considered low risk in fetal and maternal complication prediction. The sensitivity was 32.1%, the specificity 98.4%, the positive predictive value (PPV) 94.4%, and the negative predictive value (NPV) 63.3%. A cutoff value of 10, leading to the highest Youden index, performed best at detecting overall complications, increasing sensitivity to 69.8% and the NPV to 76.8%. at the cost of a reduced specificity and PPV. CONCLUSIONS: In pregnancies with abnormal uterine artery Doppler in the second trimester, an sFlt-1/PlGF cutoff value greater than equal to 38 improves its predictive power for adverse events.

A meta-analysis of treatment for early-stage cervical cancer: open versus minimally invasive radical trachelectomy.

BACKGROUND: In previous systematic reviews, meta-analysis was lacking, resulting in the statistical difference between the data of different surgeries being impossible to judge. This meta-analysis aims to contrast the fertility results and cancer outcomes between open and minimally invasive surgery. METHOD: We systematically searched databases including PubMed, Embase, Cochrane, and Scopus to collect studies that included open and minimally invasive radical trachelectomy. A random-effect model calculated the weighted average difference of each primary outcome via Review Manager V.5.4. RESULT: Eight studies (1369 patients) were incorporated into our study. For fertility results, the Open group excels MIS group in pregnancies-Third trimester delivery [OR = 2.68; 95% CI (1.29, 5.59); P = 0.008]. Nevertheless, there is no statistical difference in clinical pregnancy, miscarriage, and second-trimester rate. Concerning cancer outcomes, no difference was detected in the overall survival [OR = 1.56; 95% CI (0.70, 3.45); P = 0.27] and recurrence [OR = 0.63; 95% CI (0.35, 1.12); P = 0.12]. Concerning surgery-related outcomes, the comprehensive effects revealed that the estimated blood loss of the Open group was higher than that of the MIS group[MD = 139.40; 95% CI (79.05, 199.75); P < 0.0001]. However, there was no difference between the postoperative complication rate in the two groups [OR = 1.52; 95% CI (0.89, 2.60); P = 0.12]. CONCLUSION: This meta-analysis suggested that the fertility result of the Open group may be better than the MIS group, while the MIS group has better surgery-related outcomes. Owing to the poor cases of our study, a more robust conclusion requires more relevant articles in the future. SYSTEMATIC REVIEW REGISTRATION: PROSPERO CRD42022352999.

A case report of dangerous pelvic infundibulum ligament in the second trimester of pregnancy with massive hemorrhage.

RATIONALE: Abdominal pregnancy is a rare ectopic pregnancy and its diagnosis and treatment are more challenging than those of other ectopic pregnancies. Because of a variable pregnancy site, abdominal pregnancy is associated with an increased risk of fatal abdominal hemorrhage, and consequently, an increased risk of maternal death compared with intrauterine pregnancy. DIAGNOSES: Pelvic infundibulum ligament pregnancy complicated with massive hemorrhage. PATIENT CONCERNS: 42-year-old pregnant woman who did not undergo an obstetric examination during the first trimester presented with sudden abdominal pain during the second trimester. Abdominal pregnancy was confirmed after emergency treatment, causing difficulty in the comprehensive preoperative evaluation.Interventions: In order to save the patient life, we actively carried out surgical treatment. OUTCOMES: The patient recovered well after the operation and was discharged on the 11th postoperative day. Blood ß-human chorionic gonadotropin (ß-hCG) levels and routine blood test results were normal 1 month after the surgery, and the patient had recovered. LESSONS: Several challenges are encountered in the diagnosis of abdominal pregnancy with regard to insufficient economic, cultural, and medical resources. In case of ectopic pregnancies, surgery should be the first choice of treatment, and preparations of blood transfusion are essential to combat the risk of rapid hemorrhagic shock caused by placenta implantation in the infundibulum ligament of the pelvis. The operation must be performed by experienced obstetricians and gynecologists.

A cross-sectional survey of women's views and preferences for preterm birth screening and treatment.

OBJECTIVES: Primary outcomes were to determine; 1) the desire for more patient information from healthcare professionals on preterm birth (PTB) prevention 2) the desire for PTB screening surveillance or participation in research or 3) the acceptability of transvaginal ultrasound (TVUS) or vaginal examinations to predict spontaneous PTB. METHODS: A 19-question, piloted, self-administered survey was completed by unselected pregnant women in a tertiary maternity hospital in Dublin, Ireland. Data was collected to include maternal socio-demographics, past obstetric history, and current pregnancy details, in addition to views and preferences on PTB screening and preventative treatments. Statistical analysis to include binary and multinomial regression was performed by IBM SPSS Statistics for Windows (Version 29.0). RESULTS: 277 women completed the study survey. 9.4% of women had attended the preterm birth surveillance clinic (PSC). 75.1% of respondents indicated a preference for more information from healthcare professionals about PTB. 65% reported that TVUS and vaginal examinations were acceptable in pregnancy. The acceptability of antenatal examinations was significantly influenced by ethnicity; white European (OR 2.58, CI 1.12-5.95, p = 0.003) and Asian (OR 3.39, CI 1.18-9.67, p = 0.02). Discomfort (25.3%) and vaginal bleeding (11.9%) were the most frequently reported concerns about TVUS. 95.7% of unselected women indicated that they would accept treatment to prevent PTB. Vaginal progesterone (53.8%) was preferred treatment compared to cervical cerclage (15.9%) or cervical pessary (16.6%). 55.6% of respondents stated they attend or wish to attend for additional appointments or research opportunities for PTB screening. Women with a previous PTB or second trimester miscarriage were more likely to attend or wish to attend for PTB screening (OR 3.23, CI 1.34-7.79, p = 0.009). CONCLUSION: PTB is an important healthcare priority for pregnant women in Ireland. However, women require more information, counselling and reassurance about the utility and safety of TVUS in PSCs.
