Obstetrics and Gynecology Jun 2024To evaluate fertility outcomes based on size and number of intramural leiomyomas and outcomes after removal.
OBJECTIVE
To evaluate fertility outcomes based on size and number of intramural leiomyomas and outcomes after removal.
DATA SOURCES
Online searches: MEDLINE, ClinicalTrials.gov, PubMed, Cochrane Library, and PROSPERO Library from 1994 to 2023.
METHODS OF STUDY SELECTION
A total of 5,143 studies were identified, with inclusion of 13 study groups.
TABULATION, INTEGRATION AND RESULTS
Outcomes for size and number of leiomyomas were reported with clinical pregnancy rates and ongoing pregnancy or live-birth rates. In data sets with maximum leiomyoma diameters of less than 6 cm for study inclusion, women with leiomyomas smaller than 3 cm had lower clinical pregnancy rates than women without leiomyomas, with an odds ratio (OR) of 0.53 (95% CI, 0.38-0.76) and, for ongoing pregnancy or live-birth rates, an OR of 0.59 (95% CI, 0.41-0.86). The ORs for clinical pregnancy rates in women with intermediately-sized leiomyomas (those between 3 cm and 6 cm) were lower than in women without leiomyomas, with an OR at 0.43 (95% CI, 0.29-0.63) and, for ongoing pregnancy or live-birth rates, an OR at 0.38 (95% CI, 0.24-0.59). In data sets without exclusion for women with larger-sized leiomyomas, clinical pregnancy rates were lower for those with leiomyomas smaller than 5 cm compared with those without leiomyomas, with an OR of 0.75 (95% CI, 0.58-0.96). Women with leiomyomas larger than 5 cm showed no differences in clinical pregnancy rate compared with women without leiomyomas, with an OR of 0.71 (95% CI, 0.32-1.58). Although women with a single leiomyoma in any location had no differences in outcomes, those with more than one leiomyoma had lower clinical pregnancy rates and ongoing pregnancy or live-birth rates, with an OR of 0.62 (95% CI, 0.44-0.86) and 0.57 (95% CI, 0.36-0.88), respectively. The clinical pregnancy rate for women undergoing myomectomy for intramural leiomyomas was no different than those with intramural leiomyomas in situ, with an OR of 1.10 (95% CI, 0.77-1.59).
CONCLUSION
Even small intramural leiomyomas are associated with lower fertility; removal does not confer benefit. Women with more than one leiomyoma in any location have reduced fertility.

Review
PURPOSE
Pregnancy is a known risk factor for Pituitary Apoplexy (PA) but there is a lack of consistency in the literature regarding non-gestational risk factors responsible for PA.
METHODS
We did a systematic review following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines to identify the non-gestational risk factors associated with the development of PA in adult patients with pituitary adenoma. Also, we discuss here a case of an elderly female with pituitary macroadenoma who was initially planned for pituitary resection electively but underwent emergency surgery after she developed PA.
RESULTS
As per screening and eligibility criteria, seven studies with 4937 study participants were included in this systematic review out of which 490 (9.92%) patients had PA, including asymptomatic subclinical PA (SPA) and symptomatic clinical PA (CPA). The macroadenomas and negative staining of the tumor were found to be a significant risk factor consistently in multivariate analysis in three and two retrospective studies, respectively. However, the results were varied for any significant difference in the risk factors for apoplexy between SPA and CPA. Similarly, there was no consistency among the studies for risk factors significantly responsible for CPA or PA compared to controls.
CONCLUSION
No single non-gestational risk factor is solely responsible for the development of PA in a pituitary adenoma compared to the control population. Tumor size (macroadenoma) and the non-functioning status of the adenoma are the only significant factors contributing independently toward an apoplectic event in most patients. Such patients can be prioritized for early pituitary tumor resection.

INTRODUCTION
The aim of this systematic review and meta-analysis was to evaluate fetal cardiac function in fetuses of mothers with diabetes compared to those of mothers without diabetes using 2D-STE.
METHODS
Embase, MEDLINE and CENTRAL were searched for observational studies on 2D-STE fetal left and right ventricular global longitudinal strain and strain rate that included singleton, non-anomalous pregnancies complicated by pregestational or gestational diabetes mellitus compared to uncomplicated pregnancies. The strain values were pooled per 4 weeks of gestation for meta-analysis using random-effects models.
RESULTS
Fifteen studies met the criteria, including 990 fetuses of diabetic mothers and 1,645 control fetuses. The study design was cross-sectional in fourteen studies and longitudinal in one study. Gestational age, type of diabetes, ultrasound device and 2D-STE software varied between the studies. Glycemic control and type of treatment were often lacking. In fetuses of diabetic mothers versus healthy mothers, left ventricular strain was significantly decreased (7 studies), increased (1 study) or not significantly different (7 studies). Right ventricular strain was decreased (7 studies), increased (1 study) or not different (2 studies). Left ventricular strain rate was decreased (3 studies), increased (1 study) or not different (2 studies). Right ventricular strain rate was increased (1 study) or not different (2 studies).
CONCLUSION
Fetuses of mothers with diabetes show evidence of systolic dysfunction, which is more visible in the right ventricle. Contradictory results are probably due to suboptimal study designs and variation in gestational age, diabetes severity, image acquisition and software. Large prospective longitudinal studies are needed to assess fetal myocardial function with 2D-STE in pregestational diabetes mellitus type 1 and 2 and gestational diabetes mellitus pregnancies. The influence of glycemic control, BMI and treatment should be evaluated.

Meta-Analysis Review
The systematic review and meta-analysis were conducted to ascertain the prevalence of anemia, iron deficiency (ID), and iron deficiency anemia (IDA) among Chinese pregnant women. A total of 722 articles on maternal anemia during pregnancy published between January 2010 and December 2020 were compiled, and a systematic review and meta-analysis were conducted on 57 eligible studies including 1,376,204 pregnant women to ascertain the prevalence of anemia and the prevalence in different subgroups. The results showed that the prevalence of anemia, ID, and IDA among pregnant women in China were 30.7% (95% CI: 26.6%, 34.7%), 45.6% (95% CI: 37.0%, 54.2%), and 17.3% (95% CI: 13.9%, 20.7%), respectively. All prevalence increased with the progression of the pregnancy. There were sizable regional variations in the prevalence of anemia, ID, and IDA. Generally, lower prevalence was observed in the economically more advanced eastern region of the country, while the prevalence of ID was higher in the eastern region than that in the western region. The prevalence of anemia and IDA in rural areas was higher than that in urban areas, but ID prevalence was higher in urban areas. In conclusion, the regional differences and urban-rural disparities in the prevalence of anemia indicate the need for more context-specific interventions to prevent and treat anemia. It was found that dietary factors were one of the major causes of anemia, and iron-containing supplements and nutrition counseling could be effective interventions to reduce the prevalence of anemia, ID, and IDA among Chinese pregnant women.

Review
Coronary artery disease (CAD) and hypertension significantly contribute to cardiovascular morbidity and mortality. MicroRNAs (miRNAs) have recently emerged as promising biomarkers and therapeutic targets for these conditions. This systematic review conducts a thorough analysis of the literature, with a specific focus on investigating miRNA expression patterns in patients with CAD and hypertension. This review encompasses an unspecified number of eligible studies that employed a variety of patient demographics and research methodologies, resulting in diverse miRNA expression profiles. This review highlights the complex involvement of miRNAs in CAD and hypertension and the potential for advances in diagnostic and therapeutic strategies. Future research endeavors are imperative to validate these findings and elucidate the precise roles of miRNAs in disease progression, offering promising avenues for innovative diagnostic tools and targeted interventions.

Meta-Analysis
BACKGROUND
Endometriosis is a chronic and debilitating disease that can affect the entire reproductive life course of women, with potential adverse effects on pregnancy. The aim of the present study is to investigate the association between hypertensive disorders in pregnancy and endometriosis.
METHOD
Relevant articles were searched from the Cochrane Library, PubMed, Scopus and Web of Science from inception up to December 2023. The full-text observational studies published in English that had a confirmed diagnosis of endometriosis were included. The case group included pregnant women diagnosed with endometriosis at any stage, while the control group consisted of pregnant women who had not been previously diagnosed with endometriosis. Two authors extracted and analyzed the data independently. Disagreements were reconciled by reviewing the full text by a third author. Endnote X9 was used for screening and data extraction. We used fixed and random effects models in Review Manager 5.3 to analyze the pooled data. The quality of the included studies was assessed using the Downs and Black checklist.
RESULTS
Out of the 9863 articles reviewed, 23 were selected for meta-analysis. According to the results of this study, there was an association between endometriosis and gestational hypertension (OR = 1.11, 95% CI: 1.06, 1.16; I = 45%, P < 0.00001; N = 8), pre-eclampsia (OR = 1.26, 95% CI: 1.18, 1.36; I = 37%, P < 0.00001; N = 12), and hypertensive disorders in pregnancy (OR = 1.13, 95% CI: 1.06, 1.21; I = 8%, P = 0.0001; N = 8).
CONCLUSIONS
This study confirmed that endometriosis may elevate the risk of developing gestational hypertensive disorders. Raising awareness of this issue will help to identify effective strategies for screening and early diagnosis of hypertensive disorders in pregnancy.

Review
BACKGROUND
Vascular Ehlers-Danlos syndrome (vEDS) is a hereditary connective tissue disorder associated with an elevated risk of vascular, uterine and digestive complications. Managing pregnancy in this context can be a challenge.
OBJECTIVES
To systematically review the literature data on the complications in pregnancy associated with vEDS.
SEARCH STRATEGY
We searched the Pubmed Medline and Embase databases for articles using the following terms "vascular Ehlers-Danlos syndrome" or "vEDS" AND "pregnancy".
SELECTION CRITERIA
Women with vEDS.
DATA COLLECTION AND ANALYSIS
We searched the PubMed® MEDLINE® database for publications evaluating obstetric outcomes in women with vEDS.
MAIN RESULTS
A total of 121 publications were screened, with six (accounting for 412 pregnancies) included in our review. Of the women included in this sample, 30% were infertile. The miscarriage rate was 13.8% (57/412) and 8.8% of the live births were premature. Obstetric anal sphincter injuries occurred in 11.3% (23/203) of the deliveries. The maternal mortality rate per pregnancy was 5.7%.
CONCLUSIONS
Women with vEDS present an elevated risk of uterine rupture, vascular events, digestive events and death during pregnancy. Women appear to be most at risk during the peripartum period; to avoid expulsive efforts, a caesarean section should be scheduled at 37 weeks of gestation.

For the same age, sex, and dosage, there can be significant variation in fertility outcomes in childhood cancer survivors. Genetics may explain this variation. This study aims to: (i) review the genetic contributions to infertility, (ii) search for pharmacogenomic studies looking at interactions of cancer treatment, genetic predisposition and fertility-related outcomes. Systematic searches in MEDLINE Ovid, Embase Classic+Embase, and PubMed were conducted using the following selection criteria: (i) pediatric, adolescent, and young adult cancer survivors, below 25 years old at the time of diagnosis, (ii) fertility outcome measures after cancer therapy, (iii) genetic considerations. Studies were excluded if they were (i) conducted in animal models, (ii) were not published in English, (iii) editorial letters, (iv) theses. Articles were screened in Covidence by at least two independent reviewers, followed by data extraction and a risk of bias assessment using the Quality in Prognostic Studies tool. Eight articles were reviewed with a total of 29 genes. Outcome measures included sperm concentration, azoospermia, AMH levels, assessment of premature menopause, ever being pregnant or siring a pregnancy. Three studies included replication cohorts, which attempted replication of SNP findings for NPY2R, BRSK1, FANCI, CYP2C19, CYP3A4, and CYP2B6. Six studies were rated with a high risk of bias. Differing methods may explain a lack of replication, and small cohorts may have contributed to few significant findings. Larger, prospective longitudinal studies with an unbiased genome-wide focus will be important to replicate significant results, which can be applied clinically.

Review
BACKGROUND
Schistosome egg deposition in pregnant women may affect the placenta of infected mothers and cause placental schistosomiasis (PS). Histopathological examination of placental tissue is an inadequate detection method due to low sensitivity. So far, there has not been any systematic review on PS.
METHODS
We conducted a systematic literature search on PubMed, EMBASE, and Medline and included all publications that reported microscopically confirmed cases of PS, as well as the relevant secondary literature found in the citations of the primarily included publications.
RESULTS
Out of 113 abstracts screened we found a total of 8 publications describing PS with a total of 92 cases describing egg deposition of dead and/or viable eggs and worms of and in placental tissue. One cross-sectional study investigating the prevalence of PS and its association with adverse birth outcomes, found 22% of placentas to be infested using a maceration technique but only <1% using histologic examination. Additionally, no direct link to deleterious pregnancy outcomes could be shown.
CONCLUSIONS
PS is a highly unattended and underdiagnosed condition in endemic populations, due to a lack of awareness as well as low sensitivity of histopathological examinations. However, PS may play an important role in mediating or reinforcing adverse birth outcomes (ABO) such as fetal growth restriction (FGR) in maternal schistosomiasis, possibly by placental inflammation.

Effectiveness of behavioural change interventions to influence maternal and child healthcare-seeking behaviour in low and lower-middle-income countries: A systematic review of literature.
While behavioural change interventions are utilized in low- and lower-middle-income countries and may be essential in reducing maternal and child mortality, evidence on the effectiveness of such interventions is lacking. This review provides evidence on the effectiveness of behavioural change interventions designed to improve maternal and child healthcare-seeking behaviour in low- and lower-middle-income countries. We searched three electronic databases (PUBMED, EMBASE, and PsycINFO) for articles published in English and French between January 2013 and December 2022. Studies that evaluated interventions to increase maternal and child healthcare utilization, including antenatal care, skilled birth care, postnatal care, immunization uptake, and medication or referral compliance, were included. We identified and included 17 articles in the review. Overall, 11 studies found significant effects of the behavioural change interventions on the desired healthcare outcomes, 3 found partially significant effects, and 3 did not observe any significant impact. A major gap identified in the literature was the lack of studies reporting the effect of behavioural change interventions on women's non-cognitive and personality characteristics, as recent evidence suggests the importance of these factors in maternal and child healthcare-seeking behaviour in low-resource settings. This review highlights some intervention areas that show encouraging trends in maternal and child healthcare-seeking behaviours, including social influence, health education, and nudging through text message reminders.
