The optic nerve sheath in hypertensive disorders of pregnancy and perinatal outcomes: a cohort study.

BACKGROUND: Preeclampsia is implicated in 14% of maternal deaths worldwide, mostly due to complications such as intracranial hemorrhage and cerebral edema. Cerebral edema increases intracranial pressure, which can be predicted by ultrasonographic measurement of the optic nerve sheath diameter (ONSD). Greater diameters have been reported in women with preeclampsia and eclampsia; however, data are lacking on the possible association with maternal and neonatal adverse outcomes. This study aimed to determine whether there is an association between hypertensive disorders of pregnancy and the ONSD, and between this measurement and maternal and neonatal adverse outcomes. METHODS: This was a cohort study involving 183 women in the third trimester of pregnancy or within 24 h following childbirth, distributed as follows: control group (n = 30), gestational hypertension (n = 14), chronic hypertension (n = 12), preeclampsia without severe features (n = 12), preeclampsia with severe features (n = 62), superimposed preeclampsia (n = 23) and eclampsia (n = 30). The participants underwent ocular ultrasonography, and data on maternal and neonatal outcomes were collected from the medical records. To compare the groups, analysis of variance was used for the normally distributed numerical variables and the Kruskal-Wallis test was used for variables with non-normal distribution. Two-tailed p-values ≤ 0.05 were considered statistically significant. RESULTS: Overall comparison between the seven groups showed no statistically significant difference in the mean ONSD (p = 0.056). Nevertheless, diameters were significantly greater in the eclampsia group compared to the control group (p = 0.003). Greater diameters were associated with maternal admission to the intensive care unit (ICU) (p < 0.01) and maternal near miss (p = 0.01). There was no association between ONSD and admission to the neonatal ICU (p = 0.1), neonatal near miss (p = 0.34) or neonatal death (p = 0.26). CONCLUSIONS: No association was found between ONSD and the hypertensive disorders of pregnancy in the overall analysis; however, ONSD was greater in women with eclampsia compared to controls. Greater diameters were associated with maternal admission to the ICU and maternal near miss. These findings suggest a potential use for bedside ultrasound as an additional tool for stratifying risk in patients with hypertensive disorders of pregnancy.

Fluctuation trend of inflammatory indexes related to gestational diabetes mellitus from second trimester to third trimester of pregnancy.

OBJECTIVE: This study aims to assess the prognostic and diagnostic value of inflammatory indexes related to gestational diabetes mellitus (GDM) from the second trimester to the third trimester of pregnancy. MATERIALS AND METHODS: In this study, we randomly selected 65 pregnant women diagnosed with GDM at our hospital from December 2022 to June 2023 to form the GDM group (n = 65). Additionally, 65 pregnant women at the same gestational weeks without GDM were selected as the Normal group (n = 65). We collected gestational information and serum samples at 24 and 36 weeks of gestation from the participants. The levels of NLRP3, IL-1Ra, and TBP-2 were determined using enzyme-linked immunosorbent assay (ELISA) to explore their changes during pregnancy. Further, this study analyzed the changes in the levels of NLRP3, IL-1Ra, and TBP-2 at 24 and 36 weeks of gestation in GDM patients and their correlation with gestational diabetes mellitus. RESULTS: The study showed that pre-pregnancy body mass index (BMI), neonatal weight, gestational hypertension, and macrosomia are significantly associated with the occurrence of GDM (P < 0.05). Statistical analysis comparing the normal and GDM groups found no significant changes in the levels of NLRP3, IL-1Ra, and TBP-2 with the progression of gestation in the normal group. In contrast, in the GDM group, the levels of IL-1Ra in serum samples at 24 and 36 weeks were significantly increased (P < 0.05) while the levels of NLRP3 and TBP-2 were significantly reduced (P < 0.05). At 36 weeks, there was a positive correlation between the levels of NLRP3, IL-1Ra, and TBP-2. Compared to the normal group, the overall levels of NLRP3, IL-1Ra, and TBP-2 in the GDM group were lower (P < 0.05) and the weight of the newborns was significantly correlated with these three indicators (P < 0.05), specifically newborn weight increased with the levels of NLRP3 and TBP-2 but decreased with the increase of IL-1Ra (P < 0.05). Multifactorial logistic regression analysis further revealed that NLRP3 is an independent factor influencing GDM (P < 0.05). ROC curve analysis of the NLRP3 level at 24 weeks of gestation found that NLRP3 has a good value in predicting GDM (AUC = 0.720, 95%CI 0.630-0.809, P < 0.001) and the combined prediction of NLRP3, IL-1Ra, and TBP-2 also showed a good predictive value for GDM. CONCLUSION: The changes in NLRP3, IL-1Ra, and TBP-2 persisted throughout the 24 to 36 weeks of gestation, playing an important role in predicting the occurrence of GDM and the weight of the newborn.

Comparison of the Anaemia and Transfusion Rates of Pregnant Women Treated with Intravenous versus Oral Iron in the Third Trimester.

OBJECTIVE: To evaluate and compare the blood transfusion requirements during delivery in third-trimester pregnant women with iron deficiency anaemia (IDA) who were treated with intravenous (IV) ferric carboxymaltose (FCM) versus those treated with oral iron supplementation. STUDY DESIGN: Comparative study. Place and Duration of the Study: Bakirkoy Dr. Sadi Konuk Training and Research Hospital, Istanbul, Turkiye, from January 2017 to December 2022. METHODOLOGY: Pregnant women with haemoglobin (Hb) levels <10 g/dL in their third trimester were included. One group (n = 50) received IV FCM, while the other group (n = 96) received oral iron therapy. Key outcome measures included Hb levels at delivery and the need for a postpartum blood transfusion. Inclusion criteria were third-trimester pregnancy with IDA, and exclusion criteria included haematological or chronic systemic diseases and high-risk pregnancies. RESULTS: The mean initial Hb levels in the third trimester of pregnancy in the FCM group and oral iron group were 8.31 ± 0.96 g/dL and 9.29 ± 1.20 g/dL, respectively (p <0.001). The mean Hb levels in the delivery room were 11.09 ± 1.38 and 9.44 ± 1.16 g/dL, respectively (p <0.001). The rates of postpartum erythrocyte transfusion requirement were 6% (n = 3) and 18.75% (n = 18), respectively (p = 0.037). CONCLUSION: IV FCM administration to pregnant patients with IDA during the third trimester was found to be more effective than oral iron treatment in reducing blood transfusion rates. KEY WORDS: Anaemia, Ferric carboxymaltose, Pregnancy, Iron deficiency, Intravenous iron.

Association of SARS-CoV-2 infection during late pregnancy with maternal and neonatal outcomes.

BACKGROUND: Limited data on the impact of the coronavirus disease 2019 (COVID-19) during pregnancy on newborn outcomes are available. This study aimed to characterize and compare the clinical outcomes of newborns from women with and without the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) infection during late pregnancy. METHOD: This was a retrospective cohort study of women who were either infected or not infected with the SARS-CoV-2 virus during late pregnancy. The neonatal complications associated with COVID-19-positive pregnant women were investigated and analyzed. RESULTS: Among 2063 pregnant women over 28 weeks of gestation, 1.2%, 3.3%, and 18.7% of patients with multiple pregnancies, abnormal fetal positions, and lack of maternal or neonatal follow-up data, respectively, were excluded. Patients who were COVID-19-negative (60.6%) and -positive (16.2%) remained for further analysis. SARS-CoV-2 infection was significantly associated with higher SARS-CoV-2 infection rates in newborns (0% vs. 1.49%, P < 0.01) and longer duration of hospital stay (6.39 ± 2.2 vs. 4.92 ± 1.6, P < 0.01). However, comparing neonatal complications, including Apgar score, preterm birth, low birth weight, cesarean section rate, newborn hearing, neonatal congenital heart defects, and height and weight compliance rate of 6-month-old children, between non-infected and infected participants did not reach statistical significance. CONCLUSION: SARS-CoV-2 infection in late pregnancy has no significant impact on neonatal outcomes. After six months of follow-up of the neonates, we observed that SARS-CoV-2 infection in the third trimester of pregnancy did not affect their growth and development. Hopefully, these findings will guide management strategies and clinical practice.

Pregnancy cholestasis typically occurs in the third trimester of pregnancy and is a significant clinical condition.

AIM: The aim of this study is to determine the albumin/bilirubin ratio index and the aspartate aminotransferase (AST)/alanine aminotransferase ratio (ALT) index in patients diagnosed with cholestasis during pregnancy, and to demonstrate their correlation with liver damage. Additionally, potential strategies to prevent liver damage will be elucidated. MATERIALS AND METHOD: Our study is a retrospective study. A total of 4019 pregnant women aged between 18 and 40 years, presenting with itching complaints at 32-36 weeks of gestation, were screened at the Department of Obstetrics and Gynecology, Istanbul Training and Research Hospital of Health Sciences University between January 1, 2018, and December 31, 2023. Among them, 104 pregnant women without any other accompanying diseases were diagnosed with Gestational Cholestasis. Among the 104 diagnosed women, 78 met the inclusion criteria and were included in the study. Twenty-six women were excluded from the study due to missing albumin and total bilirubin values or due to blood samples being taken at different times. The serum albumin/bilirubin ratio index and the alanine aminotransferase/aspartate aminotransferase ratio index were calculated and statistically compared between pregnant women diagnosed with cholestasis and healthy pregnant women at the same gestational week. FINDINGS: We found that AST, ALT, albumin, and total bilirubin levels were significantly higher in pregnant women diagnosed with cholestasis compared to the control group (p < 0.05). The AST/ALT index in the case group was significantly lower compared to the control group. However, there were no significant differences found between the case and control groups regarding the albumin/total bilirubin index and ALBI grade. When comparing ALBI grades in cases, no significant differences were found in terms of patients' age, gestational week, AST, ALT, and AST/ALT index. When compared according to ALBI grades, the albumin level was higher in patients with ALBI grade I compared to grade II, and in patients with grade II compared to grade III. The total bilirubin level was significantly higher in patients with ALBI grade III compared to grades I and II, but there was no significant difference between grades I and II. No significant differences were found among the groups separated according to ALBI grades when FBA values were compared. CONCLUSION: In this study, the negative correlation between lower AST/ALT ratio and FBA values in patients with severe cholestasis suggests the need for careful consideration regarding future liver damage. The lack of difference in ALBI score between the case and control groups, as well as the absence of correlation with FBA values, indicates the necessity to evaluate ALBI score based on patients' long-term prognosis.

Third-Trimester Cardiovascular Function and Risk of Hypertensive Disorders of Pregnancy.

BACKGROUND: Whether cardiovascular dysfunction is associated with preeclampsia in women without fetal growth restriction (FGR) is unclear. Our objective was to investigate associations between third-trimester cardiac output (CO) and systemic vascular resistance and risk of hypertensive disorders of pregnancy in women with and without FGR. METHODS AND RESULTS: A case-cohort study in 906 pregnant women in Denmark with repeated third-trimester cardiac function assessments was performed using the Ultrasound Cardiac Output Monitor 1A. Using Cox regression, we compared rates of hypertensive disorders of pregnancy in women with low, normal, and high CO and normal and high systemic vascular resistance, by FGR status and gestational age, and evaluated associations between a third-trimester drop in CO or increase in systemic vascular resistance and preeclampsia risk in women without FGR. The analysis included 249 women with preeclampsia (42 with FGR) and 119 women with gestational hypertension. Low CO was strongly associated with preeclampsia at <37 weeks (women with FGR: hazard ratio [HR], 5.25 [95% CI, 1.26-21.9]; women without FGR: HR, 2.19 [95% CI, 1.07-4.48]). Our results also suggested an association between low CO and preeclampsia at ≥37 weeks among women without FGR (HR, 1.31 [95% CI, 0.84-2.03]), and between a third-trimester drop in CO >75th percentile and preeclampsia in women without FGR (odds ratio, 1.91 [95% CI, 0.84-4.36]). High systemic vascular resistance was strongly associated with increased rates of all forms of hypertensive disorders of pregnancy. CONCLUSIONS: Low CO is associated with preeclampsia risk in women with and without FGR, particularly before 37 weeks. Repeated measurements of third-trimester cardiovascular function might identify women without FGR for monitoring for preeclampsia, but this result needs to be confirmed in other studies.

Understanding the body image perception of pregnant women during their third trimester in a tertiary care setting in Southern India.

BACKGROUND: Pregnancy is a known physiological phenomenon characterized by various changes in the body. The physical and physiological changes that occur during pregnancy may impact the body image which may lead to implications such as body image issues or poor eating habits among pregnant women. This study aimed to analyze the body image perception of pregnant women in their third trimester. METHODS: This cross-sectional survey which involved the administration of a Multidimensional Body Self-Relations Questionnaire (MBSRQ), was conducted among pregnant women between 28 and 40 weeks of gestation in a tertiary care setting in Southern India. Descriptive statistics were used to report the demographic characteristics of the respondents. A one-sample t-test was used to analyze the difference between the present sample scores and the published norms of MBSRQ. Univariate Logistic Regression was done to find the association between the demographic variables and subdomains of MBSRQ. RESULTS: The mean age of the respondents (n = 246) was 29.5 years, and the period of gestation was 33.4 weeks. With mean scores of subscales of MSRQ as reference values, a greater proportion of women had higher scores on appearance orientation (52.44%), health evaluation (56.91%), and illness orientation (55.28%). Respondents scored less on appearance evaluation (52.03%) and body areas satisfaction scale (50.41%). The study found that pre-pregnancy BMI, abdominal circumference, and weight gain during pregnancy were associated with appearance orientation, overweight preoccupation, and self-classified weight. Health evaluation was associated with weight gain and Instagram use, while moderate-intensity physical activity during pregnancy was associated with higher health orientation. CONCLUSION: Although pregnant women in our setting during the third trimester were oriented towards their appearance and considered themselves healthy and fit, almost half of the respondents reported dissatisfaction with their changing bodies and appearance. Self-reported physical activity status, body mass index, weight gain, level of education, use of Instagram app, and type of family were factors found to affect pregnant body image perception. Hence, we conclude that body image perception is affected during pregnancy, and healthcare professionals should be aware of this, and the factors associated with it while addressing the health of pregnant women. CLINICAL TRIAL REGISTRATION DETAILS: The study was registered under the Clinical Trials Registry- India: CTRI/2023/08/056524. https://ctri.nic.in/Clinicaltrials/rmaindet.php?trialid=89771&EncHid=39880.12369&modid=1&compid=19 .

The Adverse Effects of Anxiety and Depression on Pregnant Women with Hypothyroidism in Late Pregnancy.

BACKGROUND: Maternal depression and anxiety during pregnancy are significant public health concerns commonly reported worldwide among pregnant women. This study aimed to investigate the impact of anxiety and depression on thyroid function, pregnancy outcomes, and sleep quality among pregnant women with hypothyroidism in the later stages of pregnancy. METHODS: Eighty cases of pregnant women with hypothyroidism in late pregnancy who were treated at Zhangjiakou First Hospital from January 2021 to October 2023 were selected for this retrospective study. The pregnant women in late pregnancy were divided into four groups according to the scores on the Hospital Anxiety and Depression Scale (HADS): control group with 20 cases, anxiety group with 18 cases, depression group with 22 cases, and anxiety-depression group with 20 cases. A comparison was made among the four groups regarding general information of pregnant women in late pregnancy, HADS scale scores, levels of free thyroxine (FT4, FT3), thyroid-stimulating hormone (TSH), occurrence of adverse pregnancy outcomes, and sleep quality at different time periods. RESULTS: There was no statistically significant difference in comparing general information among the four groups of pregnant women in late pregnancy (p > 0.05). There were statistically significant differences in HADS depression and HADS anxiety scores (p < 0.05), levels of FT4, FT3, TSH in pregnant women in late pregnancy postpartum (p < 0.05), occurrence of adverse pregnancy outcomes (p < 0.05), and comparison of sleep quality of pregnant women in late pregnancy at 1, 3, and 5 months of follow-up among the groups (F = 5.735, 23.930, 11.573, p < 0.05). CONCLUSION: Anxiety and depression significantly impact thyroid function, pregnancy outcomes, and sleep quality in pregnant women with hypothyroidism in late pregnancy, which is detrimental to the health of pregnant women in late pregnancy. Therefore, necessary interventions are needed.

Activation of peripheral leukocyte migration before spontaneous labor at term.

BACKGROUND: Leukocytes are induced to migrate into the uterus at parturition, releasing cytokines and chemokines that activate it for delivery. A specific chemotactic signal is required for these actions, and published evidence suggests that it comes from the human fetal membranes and has a time-dependent component (ie, cells obtained at term in labor migrate more than cells obtained at term not yet in labor). The hypothesis that the fetal membrane chemoattractants activate the leukocytes to become responsive for migration was tested. OBJECTIVE: This study aimed to: (1) examine the changes in leukocyte migration-responsiveness longitudinally from the late third trimester, to in labor, to 3 days postpartum; (2) explore the specific week-to-week changes in migration before delivery; (3) define the timing of chemokine receptor expression patterns in leukocytes relative to migration and the changes in cytokine and chemokine concentrations in maternal serum; (4) examine the ability of term fetal membrane-conditioned medium and term maternal serum to increase cell responsiveness; and (5) test the potential of the leukocyte migration assay to predict delivery within 1 week. STUDY DESIGN: Leukocyte migration in response to a chemoattractive extract of term human fetal membranes was studied using a modified Boyden chamber. Flow cytometry assessed migrated cell phenotypes. The relationship between the expression of chemokine receptors and migration was tested using quantitative polymerase chain reaction, the bioassay, and regression analyses. Cytokines and chemokines in maternal serum were quantified using multiplex analysis. Conditioned medium from fetal membrane explants and maternal serum were evaluated for their abilities to enhance leukocyte migration using the bioassay. The ability of the bioassay to predict term delivery was assessed using receiver-operating characteristic curve and cost-curve analysis. RESULTS: The number of leukocytes that migrated at term delivery was increased relative to the late third trimester, followed by a significant fall in numbers that migrated at 3 days postpartum (P=.002). The largest increase in migrated cells occurred 1 to 2 weeks before delivery. The messenger RNA abundance of several chemokine receptors increased in peripheral leukocytes at term in labor relative to the third trimester, and this correlated with an increase in migrated cells in 5 of 6 cases (R=0.589 to 0.897; P<.03). The concentrations of several chemokines and cytokines in maternal serum increased with labor onset. Fetal membrane explant-conditioned medium and maternal serum obtained at term labor increased the responsiveness of leukocytes to fetal membrane chemoattractive extract. The bioassay was demonstrated to predict delivery within 7 days with excellent performance characteristics using a cohort prevalence of 71.7% (positive predictive value=96.1%; negative predictive value=58.5%; sensitivity=74.2%; specificity=92.3%; positive likelihood ratio=9.25; and negative likelihood ratio=0.28). A single determination was validated to have a high degree of confidence. CONCLUSION: Term human fetal membranes release chemoattractants near the end of pregnancy that increase in ability to activate and attract an increasing number of leukocytes as gestation advances.

Spontaneous rupture of an unscarred uterus at the early third trimester due to placenta percreta: a case report.

Uterine rupture during pregnancy is a complication of placenta percreta. We present the case of a woman in her early 30s with a history of incomplete abortion treated by dilatation and curettage who was admitted with abdominal pain and vomiting at 30 weeks of gestation. She was diagnosed with thrombophilia and was administered anticoagulant drugs. After 10 hours of monitoring, the patient abruptly deteriorated. An emergency cesarean delivery showed a ruptured uterus due to placenta percreta. She accepted localized excision and uterine repair, and recovered well. Rupture of an unscarred uterus due to placental percreta is an extremely rare obstetric complication with high maternal and fetal mortality. This condition should be suspected in all pregnant women who have severe abdominal pain without being in labor. The treatment of uterine rupture due to placental percreta should be individualized, and repair of the uterus is possible in the majority of women.

Maternal vascular indices and hemodynamic parameters at 36 weeks' gestation in gestational and pre-existing diabetes mellitus.

OBJECTIVE: To compare maternal vascular indices and hemodynamic parameters at 35-37 weeks' gestation in pregnancies complicated by gestational diabetes mellitus (GDM), those with pre-existing diabetes mellitus (DM) and those without GDM or pre-existing DM. METHODS: This was a prospective observational study in women with a singleton pregnancy attending for a routine hospital visit at 35 + 0 to 36 + 6 weeks' gestation. The visit included recording of maternal demographic characteristics and medical history, and measurement of vascular indices and hemodynamic parameters using a non-invasive operator-independent device. These included carotid-to-femoral pulse-wave velocity, augmentation index, cardiac output, stroke volume, central systolic and diastolic blood pressure, total peripheral resistance and heart rate. The values in the GDM and pre-existing DM groups were compared to those in the unaffected group. RESULTS: We examined 6746 women, of whom 396 were excluded because they had chronic hypertension or developed pre-eclampsia or gestational hypertension. The study population of 6350 pregnancies contained 99 (1.6%) with pre-existing Type-I or Type-II DM and 617 (9.7%) that developed GDM, including 261 (42.3%) that were treated with diet alone, 239 (38.7%) treated with metformin alone and 117 (19.0%) treated with insulin with or without metformin. Among women with GDM and those with pre-existing DM, compared to those without GDM or pre-existing DM, there was a higher median cardiac output and heart rate, central systolic and diastolic blood pressure and pulse-wave velocity, but there was no significant difference in stroke volume or total peripheral resistance. There were no significant differences within the GDM group according to treatment type, except for higher heart rate in women treated with metformin alone compared to the group treated with diet alone. CONCLUSION: Women with GDM and those with pre-existing DM have evidence of early vascular disease in the third trimester, and this may contribute to their increased long-term cardiovascular risk. © 2024 International Society of Ultrasound in Obstetrics and Gynecology.

Repeatability and reproducibility of artificial intelligence-acquired fetal brain measurements (SonoCNS) in the second and third trimesters of pregnancy.

Artificial Intelligence (AI)-based algorithms are increasingly entering clinical practice, aiding in the assessment of fetal anatomy and biometry. One such tool for evaluating the fetal head and central nervous system structures is SonoCNS™, which delineates appropriate planes for measuring head circumference (HC), biparietal diameter (BPD), occipitofrontal diameter (OFD), transcerebellar diameter (TCD), width of the posterior horn of the lateral ventricle (Vp), and cisterna magna (CM) based on a 3D volume acquired at the level of the fetal head's thalamic plane. This study aimed to evaluate the intra- and interobserver variability of measurements obtained using this software. The study included 381 patients, 270 in their second trimester of pregnancy (70%) and 111 in the third trimester. Each patient underwent manual biometric measurements of the aforementioned structures and twice using the SonoCNS software. We calculated the intraobserver variability between the manual measurements and the average of the automated measurements, as well as the interobserver variability for automated measurements. We also compared the median examination time for manual and automated measurements. The interclass correlation coefficients (ICC) for interobserver and intraobserver variability for parameters BPD, HC, and OFD ranged from good to excellent reproducibility in the general population and subgroups (> 0.75). CM and Vp measurements, both in the general population and subgroups, fell into the category of moderate (0.5-0.75) and poor reproducibility (< 0.5). TCD measurements showed moderate (> 0.5) to good reproducibility (0.75-0.9), and OFD showed good and excellent reproducibility. The assessment of the biometry of fetal head structures using SonoCNS took an average of 63 s compared to 14 s for manual measurement (p < 0.001). The SonoCNS™ software is characterized by good to excellent reproducibility and repeatability in the measurement of fetal skull biometry (BPD, HC, and OFD), with poorer performance in measurements of intracranial structures (CM, Vp, TCD). Apart from biometric parameters, the software is useful in clinical practice for delineating appropriate planes from the acquired volume of the fetal head and shortening examination time.

Successful Conservative Treatment of Maternal Spontaneous Unilateral Adrenal Hemorrhage Causing Severe Anemia in the Third Trimester of Pregnancy-A Case Report.

We present the case of a 32-year-old pregnant woman in the 32 + 3 weeks of pregnancy who presented to the hospital with an exacerbation of pain in the right flank. The diagnostic evaluation revealed the presence of severe anemia and a spontaneous adrenal hemorrhage (SAH) in the right adrenal gland. The patient was transferred to the Perinatology, Obstetrics and Gynecology Clinic with the intention of undergoing preterm childbirth. However, the doctors made a risky decision to wait until week 37 and to terminate the pregnancy at that point. The decision was right, as a cesarean section was performed without complications, and the patient gave birth to a healthy child. Spontaneous adrenal hemorrhage (SAH) is a rare condition, defined as spontaneous hemorrhage without trauma or anticoagulant therapy. Due to bleeding and damage to the adrenal cortex, SAH can lead to adrenal insufficiency. Because of its non-specific symptoms and potentially fatal outcomes for the patient and fetus, it should be considered during diagnostics.

Relationship between maternal serum sFlt-1 level and placenta accreta spectrum disorders in the third trimester.

PURPOSE: This study aims to evaluate whether the third-trimester soluble fms-like tyrosine kinase-1 (sFlt-1) serum levels could be related to placenta accreta spectrum (PAS) disorders and the severity of postpartum blood loss. METHODS: This was a nested case-control study which compared serum sFlt-1 level between gravid women with or without PAS disorders. Spearman correlation analysis was conducted to explore the relationship between sFlt-1 level and the volume of postpartum blood loss. Confounding factors were adjusted to avoid the impact on the results. RESULTS: Sixty gravid women were enrolled: 36 women in the PAS group and 24 women in the non-PAS group. Women in the PAS group had a median sFlt-1 level of 9407.1 [2745.9-21,691.5] pg/ml, whereas women in the non-PAS group had a median sFlt-1 level of 25,779.2 [14317.1-35,626.7] pg/ml, (p < 0.001). The sFlt-1 level was negatively related to the volume of postpartum blood loss (r = - 0.358, p = 0.041). After adjusting for maternal age and gestational age at blood taking, sFlt-1 level showed no significant relationship with PAS disorders (p = 0.245) and postpartum blood loss (p = 0.526). CONCLUSION: Third-trimester sFlt-1 serum level is not independently associated with PAS disorders or postpartum blood loss after adjusting for confounding factors.

Comparison of maternal and neonatal morbidity in transvaginal versus transabdominal cerclage patients: A retrospective study from two tertiary hospitals.

OBJECTIVE: To compare the maternal and neonatal morbidity in patients with transvaginal (TVC) versus transabdominal (TAC) cerclage. MATERIALS AND METHODS: Retrospective analysis of patients who received cervical cerclage and terminated the pregnancy in the second trimester or third trimester in two tertiary hospitals. Data on basic clinical characteristics, predelivery maternal morbidity, intrapartum morbidity, postpartum morbidity and neonatal morbidity of TVC patients and TAC patients were analysed and compared. RESULTS: Seventy-two TVC patients and 120 TAC patients were included. The rates of abnormal fetal presentation and placental disorders were significantly higher in TAC patients than that in TVC patients (21.67% vs 5.56% and 18.33% vs 4.17%, respectively). The rates of premature rupture of membranes and intrauterine infection were significantly higher in TVC patients than that in TAC patients (25.00% vs 2.50% and 11.23% vs 3.33%, respectively). Compared with TVC patients, the rates of estimated intrapartum hemorrhage ≥500 ml, uterine rupture and cesarean delivery in the third trimester were significantly higher in TAC patients than in TVC patients. Gestational age at delivery and neonatal morbidity were comparable between TVC patients and TAC patients. CONCLUSION: Compared with TVC patients, TAC patients were associated with a significantly higher incidence of maternal morbidity in placental disorders, abnormal fetal presentation, intrapartum hemorrhage ≥500 ml and uterine rupture.

Predictive value of short cervix in early third trimester for preterm birth in women with normal mid-trimester cervical length.

BACKGROUND: Short cervical length in the mid-trimester is a powerful predictor of preterm birth (PTB). However, clinical significance of cervical length in the third trimester for predicting PTB has not been established yet. OBJECTIVE: To examine the predictive role of a shortened cervix in the third trimester for PTB in women who had a normal cervical length in the second trimester STUDY DESIGN: This retrospective cohort study included women who underwent cervical length measured at least once in both the second trimester (16+0 weeks to 27+6weeks) and the early third trimester (28+0 weeks to 33+6 weeks). Women with short cervical length in the second trimester, those with multiple pregnancies, those who underwent cerclage operation, and those who had iatrogenic PTB were excluded. The study population was divided into two groups based on cervical length in the third trimester: a short cervix (≤25 mm) group and a control group (>25 mm). Rates of PTB (<37 weeks) were compared between two groups. Predictive performances of cervical length in the third trimester for PTB were assessed. RESULTS: Women with a short cervical length at 28+0 to 33+6 weeks accounted for 12.6% (n=717) of the total study population (n=5682). PTB rate was 9.5% in the short cervix group, which was significantly higher than that (3.2%) in the control group (P<.001). The adjusted odds ratio for short cervical length on PTB was 2.73 (95% CI: 1.96-3.79). A short cervix in the third trimester had a sensitivity of 30.1%, a specificity of 88.1%, a positive predictive value of 9.5%, and a negative predictive value (NPV) of 96.8% in predicting PTB. The addition of third-trimester cervical length to the predictive model significantly increased the area under the curve from 0.64 (95% CI: 0.60-0.68) to 0.67 (95% CI: 0.63-0.71) (P=.002), demonstrating improved predictive performance. CONCLUSION: Approximately 13% of women with normal cervical length in the mid-trimester had a short cervical length after 28 weeks, which increased the risk of PTB. The high specificity and NPV of third-trimester cervical length measurements underscore their critical utility in identifying women at low risk for preterm delivery.

KANET evaluation in patients with SARS-CoV-2.

OBJECTIVES: To determine a possible correlation between SARS-CoV-2 infection during pregnancy and altered fetal behavior. METHODS: Kurjak's antenatal neurodevelopmental test (KANET) was applied from 28 to 40 weeks in 38 gestations (group A) diagnosed with COVID-19 infection during the first week and 43 non-COVID pregnant women (group B). RESULTS: No statistically significant differences considering maternal age (33±3.9 years for group A vs. 31±4.1 years for group B) and gestational age (33±1.6 weeks for group A compared to 33±2.1 weeks for group B) were observed. KANET scores were not different between the two groups. CONCLUSIONS: Fetal behavior differences are not altered in women diagnosed with SARS-CoV-2 infection during the third trimester of pregnancy.

Association between late pregnancy prehypertension and adverse outcomes among newborns of women delivered at a tertiary hospital in Eastern Uganda: a prospective cohort study.

BACKGROUND: Prehypertension during pregnancy is currently not considered as a high-risk pregnancy state in existing guidelines despite recent research correlating it with higher rates of morbidity and mortality in both the mother and the fetus. Studies on prehypertension have not been conducted in Africa despite high rates of poor neonatal outcomes. AIMS: The study aimed to determine the association between late pregnancy prehypertension and adverse outcomes in newborns of women with late pregnancy prehypertension at Jinja Regional Referral Hospital. METHODS AND MATERIALS: Between September 2022 and January 2023, a hospital-based prospective cohort study including 300 pregnant women was conducted. Participants were divided according to third-trimester blood pressure, as determined by the JNC-8 criteria. Following hospital admission for labor and delivery, 150 normotensive women and 150 prehypertensive women were identified and followed until delivery, and their neonates were followed until death or hospital discharge. A p value of ≤ 0.05 was the threshold for statistical significance when comparing the groups using the relative risk, X2, and Mantel-Haenszel adjustment. RESULTS: Composite adverse neonatal outcomes were more common in prehypertensive women compared to normotensive women (48.67% versus 32.67%), particularly Small-for-Gestation Age (SGA), stillbirth, and composite adverse neonatal outcomes had significantly higher likelihood, with aRRs of 1.63 (95% CI 1.10-2.42, p = 0.037), 9.0 (95% CI 1.15-70.16, p = 0.010), and 1.55 (95% CI 1.16-2.08, p < 0.001), respectively. By a linear model, birthweight decreased by 45.1 g for every 10 mmHg rise in systolic blood pressure (p = 0.041, Pearson correlation of -0.118). CONCLUSION AND RECOMMENDATIONS: Prehypertension in late pregnancy increased risks for adverse neonatal outcomes, thus a need to potentially lower pregnancy hypertension cut-off levels possibly through adopting the ACC/AHA blood pressure definitions for pregnant women.

Factors affecting poor sleep quality in last trimester pregnant women: a cross-sectional research from Turkey.

OBJECTIVE: The aim of the study was to determine the factors affecting poor sleep quality in the last trimester pregnant women. METHODS: A cross-sectional study was conducted at a tertiary care maternity hospital in Ankara, Turkey. The research was conducted between May and September 2019 with 570 pregnant women in the last trimester. The data were collected through the Personal Information Form, Pittsburgh Sleep Quality Index, International Physical Activity Questionnaire Short Form, Restless Legs Syndrome Form, Brief Fatigue Inventory, and Perceived Stress Scale. RESULTS: The mean Pittsburgh Sleep Quality Index score of the pregnant women was 5.98±3.31, and 48.9% of them were found to have over five Pittsburgh Sleep Quality Index scores. Hemoglobin levels, income perceptions, smoking habits, attending pregnant schools, experiencing leg pains or cramping, experiencing back, waist, or neck pains, Restless Legs Syndrome, fatigue levels, and perceived stress levels of the pregnant women were found to be important determinants of sleep quality (p<0.05). CONCLUSION: According to the findings, increasing hemogram levels, attending antenatal education programs, and improving the ability of pregnant women to manage stress are opportunities to improve sleep quality during pregnancy. Careful evaluation of pregnant women in terms of insomnia and affecting factors can be suggested during antenatal follow-up.

Predictive effect of insomnia on quality of life in last trimester pregnant women: A cross-sectional study.

This study was conducted to determine the predictive effect of insomnia on quality of life in last trimester pregnant women. This study is a cross-sectional study. The sample of the study consisted of 309 women who were pregnant in the last trimester and were followed up in the university hospital. The data was collected using Women's Health Initiative Insomnia Rating Scale(WHIIRS), World Health Organization Quality of Life Scale Short Form(WHOQOL-BREF). The Kolmogorov-Smirnov test was used to evaluate compliance with the normal distribution. Pearson correlation test used to examine the relationships between life quality subscales, discomforts during pregnancy, chronic disease, psychiatric disease, working status and insomnia. Hierarchical multiple linear regression analysis was used to determine the predictive factors of quality of life. There was a negative relationship between having problems in pregnancy and the physical domain and the psychological domain of quality of life. When working status and discomforts during pregnancy were controlled, it was determined that insomnia was an important predictor of physical, psychological, social relations and environmental areas of quality of life (respectively 21%, 6%, 5%, 4%,). As a result, it can be said that insomnia is one of the important areas that should be intervened to improve the quality of life in pregnant women.

Cette étude a été menée pour déterminer l'effet prédictif de l'insomnie sur la qualité de vie des femmes enceintes au dernier trimestre. Il s'agit d'une étude transversale. L'échantillon de l'étude était composé de 309 femmes enceintes au dernier trimestre et suivies à l'hôpital universitaire. Les données ont été recueillies à l'aide de l'échelle d'évaluation de l'insomnie de la Women's Health Initiative (WHIIRS), de l'échelle abrégée de la qualité de vie de l'Organisation mondiale de la santé (WHOQOL-BREF). Le test de Kolmogorov-Smirnov a été utilisé pour évaluer la conformité à la distribution normale. Le test de corrélation de Pearson a été utilisé pour examiner les relations entre les sous-échelles de qualité de vie, les désagréments pendant la grossesse, les maladies chroniques, les maladies psychiatriques, le statut professionnel et l'insomnie. Une analyse de régression linéaire multiple hiérarchique a été utilisée pour déterminer les facteurs prédictifs de la qualité de vie. Il y avait une relation négative entre le fait d'avoir des problèmes pendant la grossesse et le domaine physique et le domaine psychologique de la qualité de vie. En prenant en compte le statut professionnel et les désagréments pendant la grossesse, il a été déterminé que l'insomnie était un prédicteur important de la qualité de vie physique, psychologique, sociale et environnementale (respectivement 21 %, 6 %, 5 %, 4 %). Par conséquent, on peut dire que l'insomnie est l'un des domaines importants sur lesquels il faut intervenir pour améliorer la qualité de vie des femmes enceintes.
