Project description:Novel treatment options for uterine fibroids, such as uterine artery embolization (UAE), ultrasound-guided and magnetic resonance-guided high-intensity focused ultrasound (USgHIFU and MRgHIFU), and transcervical radiofrequency ablation (TFA) methods, are widely used in clinical practice. This systematic review and meta-analysis (CRD42022297312) aims to assess and compare reproductive and obstetric outcomes in women who underwent these minimally invasive approaches for uterine fibroids. The search was performed in PubMed, Google Scholar, ScienceDirect, Cochrane Library, Scopus, Web of Science and Embase. Risk of bias was assessed using the Newcastle-Ottawa Scale (NOS) and Cochrane guidelines. The articles were selected to meet the following eligibility criteria: (1) research article, (2) human subject research, and (3) the study of pregnancy outcomes after the treatment of uterine fibroids by either one of three methods-UAE, HIFU, and TFA. The analysis of 25 eligible original articles shows a similar rate of live births for UAE, USgHIFU, MRgHIFU, and TFA (70.8%, 73.5%, 70%, and 75%, respectively). The number of pregnancies varied considerably among these studies, as well as the mean age of pregnant women. However, the results of pregnancy outcomes for TFA are insufficient to draw firm conclusions, since only 24 women became pregnant in these studies, resulting in three live births. The miscarriage rate was highest in the UAE group (19.2%). USgHIFU was associated with a higher rate of placental abnormalities compared to UAE (2.8% vs. 1.6%). The pooled estimate of pregnancies was 17.31% to 44.52% after UAE, 18.69% to 78.53% after HIFU, and 2.09% to 7.63% after TFA. The available evidence confirmed that these minimally invasive uterine-sparing treatment options for uterine fibroids are a good approach for patients wishing to preserve their fertility, with comparable reproductive and obstetric outcomes among the different techniques.

Project description:Although the assessment of the amniotic fluid volume in pregnancy is part of the fetal wellbeing surveillance, the impact of idiopathic polyhydramnios (IP) on maternal and perinatal outcomes in unknown. The aim of this meta-analysis was to investigate the association of IP with different maternal and perinatal outcomes. We screened five electronic databases until December 2023 and performed data extraction and quality assessment using ROBINS-E in duplicates. Pooled risk ratios and 95% confidence intervals (95% CI) were calculated with a random effects model. 38 studies were included. Patients with IP were at increased risk of perinatal complications including preterm delivery (RR 1.96, 95% CI 1.35-2.86; I2 = 92%), placental abruption (RR 3.20, 95% CI 2.20-4.65; I2 = 2%), delivery via caesarean section (RR 1.60, 95% CI 1.39-1.84; I2 = 95%) and postpartum haemorrhage (RR 1.98, 95% CI 1.22-3.22; I2 = 84%). Similarly, IP was associated with increased risk of adverse perinatal outcomes including low APGAR score (RR 3.0, 95% CI 1.23-7.35; I2 = 95%), stillbirth (RR 4.75, 95% CI 2.54-8.86; I2 = 9%) and perinatal mortality (RR 4.75, 95% CI 2.67-8.48; I2 = 37%). This meta-analysis suggests that pregnant women with IP may be at increased risk of perinatal complications and adverse neonatal outcomes. However, data remains inconclusive considering the low quality and high heterogeneity of included studies.PROSPERO registration number: CRD42022359944.

Project description:BackgroundMaternal hypothyroidism has been reported to have concerns over neonatal outcomes, not only in the context of neurocognitive development but also in the short term as birth weight and neonatal jaundice.Patients and methodsWe conducted a cross-sectional retrospective study on 638 cases who delivered live births in the Aga Khan University Hospital after ethical approval. Data were collected on hypothyroid pregnant females who were diagnosed before conception or during their antenatal visits during the year 2008-2016. Neonatal outcomes were noted for birth weight, maturity, and neonatal jaundice, neonatal hypothyroidism, neonatal respiratory distress syndrome, sepsis, hypocalcaemia, congenital anomalies, need for intensive care admission, and neonatal death. Subgroup analysis was performed on the timing of diagnosis of maternal hypothyroidism. Data analysis was performed on Statistical Package for the Social Sciences version 20.0.ResultsNeonatal jaundice was the most common neonatal outcome (37.6%) in our cohort of 662 live births. Nearly 15% required intensive care unit admission, however, neonatal death was very rare. The most common clinically significant congenital anomalies were cardiovascular defects, whereas Mongolian spots were the commonest congenital condition to report. There is a statistically significant association between low birth weight (OR 1.86, 95% CI 1.0-3.2, p ≤ 0.05) and congenital anomalies (OR 2.39, 95% CI 1.4-4.0, p ≤ 0.05) with women diagnosed with hypothyroidism before pregnancy.ConclusionWe report the neonatal outcomes and spectrum of congenital anomalies of hypothyroid pregnancies diagnosed before and during conception for the first time from the region of Pakistan.KEY MESSAGEOverall, none of the neonates of hypothyroid pregnancies developed congenital hypothyroidism.Cardiovascular defects in these neonates imply extensive screening and monitoring during pregnancy.Low birth weight and congenital anomalies are associated with the timings of diagnosis of hypothyroidism in pregnancy.

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

Project description:This study aimed to review the obstetric complications during subsequent pregnancies after uterine artery embolization (UAE) for postpartum hemorrhage (PPH) by exploring the relationship between prior UAE and obstetric complications through a meta-analysis. We conducted a systematic literature review through March 31, 2021, using PubMed, Scopus, and the Cochrane Central Register of Controlled Trials in compliance with the PRISMA guidelines and determined the effect of prior UAE for PPH on the rate of placenta accreta spectrum (PAS), PPH, placenta previa, hysterectomy, fetal growth restriction (FGR), and preterm birth (PTB). Twenty-three retrospective studies (2003-2021) met the inclusion criteria. They included 483 pregnancies with prior UAE and 320,703 pregnancies without prior UAE. The cumulative results of all women with prior UAE indicated that the rates of obstetric complications PAS, hysterectomy, and PPH were 16.3% (34/208), 6.5% (28/432), and 24.0% (115/480), respectively. According to the patient background-matched analysis based on the presence of prior PPH, women with prior UAE were associated with higher rates of PAS (odds ratio [OR] 20.82; 95% confidence interval [CI] 3.27-132.41) and PPH (OR 5.32, 95% CI 1.40-20.16) but not with higher rates of hysterectomy (OR 8.93, 95% CI 0.43-187.06), placenta previa (OR 2.31, 95% CI 0.35-15.22), FGR (OR 7.22, 95% CI 0.28-188.69), or PTB (OR 3.00, 95% CI 0.74-12.14), compared with those who did not undergo prior UAE. Prior UAE for PPH may be a significant risk factor for PAS and PPH during subsequent pregnancies. Therefore, at the time of delivery, clinicians should be more attentive to PAS and PPH when women have undergone prior UAE. Since the number of women included in the patient background-matched study was limited, further investigations are warranted to confirm the results of this study.

Project description:ObjectiveTo estimate nationwide trends in the prevalence of maternal congenital heart disease (CHD) and determine whether women with CHD are more likely than women without maternal CHD to have medical and obstetric complications.MethodsThe 2000-2010 Nationwide Inpatient Sample was queried for International Classification of Diseases, 9th Revision, Clinical Modification codes to identify delivery hospitalizations of women with and without CHD. Trends in the prevalence of CHD were determined and then rates of complications were reported for CHD per 10,000 delivery hospitalizations. For Nationwide Inpatient Sample 2008-2010, logistic regression was used to examine associations between CHD and complications.ResultsFrom 2000 to 2010, there was a significant linear increase in the prevalence of CHD from 6.4 to 9.0 per 10,000 delivery hospitalizations (P<.001). Multivariable logistic regression demonstrated that all selected medical complications, including mortality (17.8 compared with 0.7/10,000 deliveries, adjusted odds ratio [OR] 22.10, 95% confidence interval [CI] 13.96-34.97), mechanical ventilation (91.9 compared with 6.9/10,000, adjusted OR 9.94, 95% CI 7.99-12.37), and a composite cardiovascular outcome (614 compared with 34.3/10,000, adjusted OR 10.54, 95% CI 9.55-11.64) were more likely to occur among delivery hospitalizations with maternal CHD than without. Obstetric complications were also common among women with CHD. Delivery hospitalizations with maternal CHD that also included codes for pulmonary circulatory disorders had higher rates of medical complications compared with hospitalizations with maternal CHD without pulmonary circulatory disorders.ConclusionThe number of delivery hospitalizations with maternal CHD in the United States is increasing, and although we were not able to determine whether correction of the cardiac lesion affected outcomes, these hospitalizations have a high burden of medical and obstetric complications.Level of evidenceII.

Project description:PurposeUterine septum in women with subfertility or previous poor reproductive outcomes presents a clinical dilemma. Hysteroscopic septum resection has been previously associated with adverse reproductive outcomes but the evidence remains inconclusive. We aimed to thoroughly and systematically appraise relevant evidence on the impact of hysteroscopically resecting the uterine septum on this cohort of women.MethodsAMED, BNI, CINAHL, EMBASE, EMCARE, Medline, PsychInfo, PubMed, Cochrane register of controlled trials, Cochrane database of systematic reviews and CINAHL were assessed to April 2020, with no language restriction. Only randomised control trials and comparative studies which evaluated outcomes in women with uterine septum and a history of subfertility and/or poor reproductive outcomes treated by hysteroscopic septum resection against control were included. The primary endpoint was live birth rate, whereas clinical pregnancy, miscarriage, preterm birth and malpresentation rates were secondary outcomes.ResultsSeven studies involving 407 women with hysteroscopic septum resection and 252 with conservative management were included in the meta-analysis. Hysteroscopic septum resection was associated with a lower rate of miscarriage (OR 0.25, 95% CI 0.07-0.88) compared with untreated women. No significant effect was seen on live birth, clinical pregnancy rate or preterm delivery. However, there were fewer malpresentations during labour in the treated group (OR 0.22, 95% CI 0.06-0.73).ConclusionOur review found no significant effect of hysteroscopic resection on live birth. However, given the limited evidence available, high-quality randomised controlled trials are recommended before any conclusive clinical guidance can be drawn.

Project description:BackgroundIncreased uterine activity (UA) may not allow adequate recovery time for foetal oxygenation.MethodsThe aim of the study was to determine if increased UA during labour is associated with an increased risk of either short- or long-term neurological injury in term neonates, or with neonatal proxy measures of intrapartum hypoxia-ischemia. MEDLINE, CINAHL, and ClinicalTrials.gov were searched using the following terms: uterine activity, excessive uterine activity, XSUA, uterine hyperstimulation, and tachysystole. Any study that analysed the relationship between UA during term labour and neurological outcomes/selected proxy neurological outcomes was eligible for inclusion. Outcomes from individual studies were reported in tables and presented descriptively with odds ratios (OR) and 95% confidence intervals (CI) for dichotomous outcomes and means with standard deviations for continuous outcomes. Where group numbers were provided, ORs and their CIs were calculated according to Altman.Main resultsTwelve studies met the inclusion criteria. Seven studies featured umbilical artery pH as an individual outcome. Umbilical artery base excess and Apgar scores were both reported as individual outcomes in four studies. No study examined long term neurodevelopmental outcomes and only one study reported on encephalopathy as an outcome. The evidence for a relationship between UA and adverse infant outcomes was inconsistent. The reported estimated effect size varied from non-existent to clinically significant.ConclusionsThere is some evidence that increased UA may be a non-specific predictor of depressed neurological function in the newborn, but it is inconsistent and insufficient to support the conclusion that an association generally exists.

Project description:Background With advances in the treatment of congenital heart disease (CHD), more women with CHD survive childhood to reach reproductive age. The objective of this study was to evaluate the maternal and neonatal outcomes of pregnancies among women with CHD in the modern era. Methods and Results We conducted a meta-analysis of peer-reviewed literature published January 2007 through June 2019. Studies were included if they reported on maternal or fetal mortality and provided data by CHD lesion. Meta-analysis was performed using random effect regression modeling using Comprehensive Meta-Analysis (v3). CHD lesions were categorized as mild, moderate, and severe to allow for pooling of data across studies. Of 2200 articles returned by our search, 32 met inclusion criteria for this study. Overall, the rate of neonatal mortality was 1%, 3.1%, and 3.5% in mild, moderate, and severe lesions, respectively. There were too few maternal deaths in any group to pool data. The rates of maternal and neonatal morbidity among women with CHD increase with severity of lesion. Specifically, rates of maternal arrhythmia and heart failure, cesarean section, preterm birth, and small for gestational age neonate are all markedly increased as severity of maternal CHD increases. Conclusions In the modern era, pregnancy in women with CHD typically has a successful outcome in both mother and child. However, as maternal CHD severity increases, so too does the risk of numerous morbidities and neonatal mortality. These findings may help in counseling women with CHD who plan to become pregnant, especially women with severe lesions.

Project description:BackgroundThe prevalence of congenital uterine anomalies in high-risk women is unclear, as several different diagnostic approaches have been applied to different groups of patients. This review aims to evaluate the prevalence of such anomalies in unselected populations and in women with infertility, including those undergoing IVF treatment, women with a history of miscarriage, women with infertility and recurrent miscarriage combined, and women with a history of preterm delivery.MethodsSearches of MEDLINE, EMBASE, Web of Science and the Cochrane register were performed. Study selection and data extraction were conducted independently by two reviewers. Studies were grouped into those that used 'optimal' and 'suboptimal' tests for uterine anomalies. Meta-analyses were performed to establish the prevalence of uterine anomalies and their subtypes within the various populations.ResultsWe identified 94 observational studies comprising 89 861 women. The prevalence of uterine anomalies diagnosed by optimal tests was 5.5% [95% confidence interval (CI), 3.5-8.5] in the unselected population, 8.0% (95% CI, 5.3-12) in infertile women, 13.3% (95% CI, 8.9-20.0) in those with a history of miscarriage and 24.5% (95% CI, 18.3-32.8) in those with miscarriage and infertility. Arcuate uterus is most common in the unselected population (3.9%; 95% CI, 2.1-7.1), and its prevalence is not increased in high-risk groups. In contrast, septate uterus is the most common anomaly in high-risk populations.ConclusionsWomen with a history of miscarriage or miscarriage and infertility have higher prevalence of congenital uterine anomalies compared with the unselected population.
