Preterm delivery (PTB) is one of the most common and serious complications of pregnancy. PTB accounts for approximately 70% of neonatal deaths and is a major cause of neonatal morbidity including respiratory distress syndrome, necrotising enterocolitis and long-term neurological disabilities. Prevention of PTB and its complications include identification among symptomatic women those at high risk of immediate delivery requiring prenatal corticosteroids administration. Transvaginal ultrasonographic evaluation of the cervical length (CL) is predictive of PTB and a value 15 mm identifies among symptomatic women approximately 70% of women who will deliver within one week. In the range of CL within 15 and 30 mm biomarkers n cervical-vaginal fluids (fetal fibronectin, phosphorylated insulin-like growth factor protein-1, placental alpha-microglobulin-, cytokines) and other ultrasonographic cervical variables (posterior cervical angle, elastography) improve the identification of women at risk, In asymptomatic women CL can be applied as screening and has been proposed as a universal screening during the second trimester in singleton gestations. The finding of a CL25mm is associated with an increased risk of subsequent PTB with a sensitivity between 30 and 60% that is improved with the combination of biomarkers. Asymptomatic women with a CL 25mm should be offered vaginal progesterone treatment for the prevention of preterm birth and neonatal morbidity. The role of cerclage and pessary is still controversial. In this review we discuss the evidence-based role of ultrasonographic cervical assessment and cervicovaginal biomarkers in the prediction of PTB in symptomatic and asymptomatic women

Abstract Background : To assess the association of sleep duration and quality with the risk of preterm birth. Methods : Relevant studies were retrieved from the PubMed and Web of Science databases up to September 30, 2018. The reference lists of the retrieved articles were reviewed. Random effects models were applied to estimate summarized relative risks (RRs) and 95% confidence intervals (CIs). Results : Ten identified studies (nine cohort studies and one case-controlled study) examined the associations of sleep duration and quality with the risk of preterm birth. As compared with women with the longest sleep duration, the summary RR was 1.23 (95% CI = 1.01–1.50) for women with the shortest sleep duration, with moderate between-study heterogeneity ( I 2 = 57.4%). Additionally, as compared with women with good sleep quality, the summary RR was 1.54 (95% CI = 1.18–2.01) for women with poor sleep quality (Pittsburgh Sleep Quality Index > 5), with high between-study heterogeneity ( I 2 = 76.7%). Funnel plots as well as the Egger’s and Begg’s tests revealed no evidence of publication bias. Conclusions : This systematic review and meta-analysis revealed that short sleep duration and poor sleep quality may be associated with an increased risk of preterm birth. Further subgroup analyses are warranted to test the robustness of these findings as well as to identify potential sources of heterogeneity.

Abstract Background & Aims Robust evidence regarding the impact of disease activity on pregnancy outcomes in women with IBD is crucial for both clinicians and patients in preparing a birth plan. We sought to perform a systematic review and meta-analysis to assess the pooled influences of disease activity on pregnancy outcomes in women with IBD. Methods We searched MEDLINE, EMBASE, and COCHRANE library to identify articles comparing pregnancy outcomes between active and inactive IBD at the time of conception or during pregnancy. A meta-analysis was performed using a random-effects model to pool estimates and report odds ratios (ORs). Results A total of 28 studies were identified as eligible for the meta-analysis. In women with active IBD, the pooled ORs for low birth weight (LBW), preterm birth, small for gestational age (SGA), spontaneous abortion, and stillbirths were 3.81 (95% confidence interval [CI] 1.81-8.02), 2.42 (95% CI 1.74-3.35), 1.48 (95% CI 1.19-1.85), 1.87 (95% CI 1.17-3.0), and 2.27 (95% CI 1.03-5.04) compared to women with inactive IBD, respectively. In the subgroup analysis based on disease type, women with active ulcerative colitis had an increased risk of LBW, preterm birth, and spontaneous abortion. Women with active Crohn’s disease had a higher risk of preterm birth, SGA, and spontaneous abortion. Conclusions Active IBD during the periconception period and pregnancy is associated with increased risk of adverse pregnancy outcomes. Our data suggest that pregnancy should be planned when the disease is quiescent, and continuous disease control is important even during pregnancy.

The alteration of the uterocervical angle (UCA) has been proposed to play an important role in spontaneous preterm birth (sPTB). The aim of this systematic review and meta-analysis was to evaluate the evidence on the UCA predictive role in sPTB. In this study, PubMed, Web of Science, Scopus, and Google scholar were systematically searched from inception up to June 2020. Inter-study heterogeneity was also assessed using Cochrane’s <i>Q</i> test and the <i>I</i><sup>2</sup> statistic. Afterward, the random-effects model was used to pool the weighted mean differences (WMDs) and the corresponding 95% confidence intervals (CIs). Eleven articles that reported second-trimester UCA of 5,061 pregnancies were included in this study. Our meta-analysis results indicate that a wider UCA significantly increases the risk of sPTB in following cases: all pregnancies (WMD = 15.25, 95% CI: 11.78–18.72, <i>p</i> &#x3c; 0.001; <i>I</i><sup>2</sup> = 75.9%, <i>p</i> &#x3c; 0.001), singleton (WMD = 14.43, 95% CI: 8.79–20.06, <i>p</i> &#x3c; 0.001; <i>I</i><sup>2</sup> = 82.4%, <i>p</i> &#x3c; 0.001), and twin pregnancies (WMD = 15.14, 95% CI: 13.42–16.87, <i>p</i> &#x3c; 0.001; <i>I</i><sup>2</sup> = 0.0%, <i>p</i> = 0.464). A wider ultrasound-measured UCA in the second trimester seems to be associated with the increased risk of sPTB in both singleton and twin pregnancies, which reinforces the clinical evidence that UCA has the potential to be used as a predictive marker of sPTB.
