“…The prevalence of MCI in this study was also in line with the studies done in Ireland, France, and India [5,10,11]. Nonetheless, the prevalence of MCI in the present and Norwegian study was higher than the previous reports from India and Pakistan [12,13]. The possible explanation for the higher prevalence in the present study relative to the Indian study might be due to a difference in the selection of study participants.…”

Background Umbilical cord may insert abnormally i.e. marginal insertion to a placenta which can cause different birth and perinatal complications. Despite the increased effort taken by different responsible bodies, the prevalence of birth and perinatal complications are still high, possibly due to anomalous cord insertion. So far, anomalous cord insertion lacks proper attention in different medical settings. Hence, the present study aims to assess the magnitude, risk factors, and adverse birth outcomes of marginal cord insertion among singleton births. Methods An institution-based cross-sectional study design was conducted. A systematic random sampling technique was used to select study participants. Data were collected by using a structured questionnaire and it was entered into epi-data version 3.1 then exported to SPSS version 20 for data cleansing and analysis. Bi-variable and multivariable logistic regressions were employed to identify risk factors and adverse outcomes associated with marginal cord insertions. Crude and adjusted odds ratio (P-value < 0.05) with a 95% confidence interval were calculated. Result The magnitude of marginal cord insertion was 6.4% (95% CI = 4.4–8.8%) in singleton pregnancies. Independent risk factors for marginal cord insertion were advanced maternal age (AOR = 2.24, 95% CI: 1.35–11.08), primiparity (AOR = 1.98, 95% CI: 1.37–8.69), maternal chronic hypertension (AOR = 3.07, 95% CI: 1.66–9.76), previous cesarean delivery (AOR = 2.51, 95% CI: 1.43–10.21), and use of intrauterine contraceptive device before pregnancy (AOR = 2.22, 95% CI: 1.36–12.30). Pregnancies complicated by marginal cord insertion are at higher risk to develop low birth weight (AOR = 2.89, 95% CI: 1.23–6.80), preterm birth (AOR = 4.00, 95% CI: 1.44–11.14), and emergency cesarean delivery (AOR = 3.68, 95% CI: 1.03–13.81). Conclusion and recommendation Marginal cord insertion is a mistreated potential risk for low birth weight, preterm birth, and emergency cesarean delivery. Routine screening of marginal cord insertion should be considered in pregnancies with advanced age, nulliparity, hypertensive disorder, history of cesarean section, and intrauterine contraceptive device usage before pregnancy.

“…The prevalence of MCI was found to be 23% (n=48) in our study which is way higher than in other studies where the prevalence ranged from 6-15% [16][17][18][19][20]. Similarly in the study by Aragie and Oumer, only 6.4% of placentas showed MCI [16].…”

AimStudy the effect of coronavirus disease-19 , caused by the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), on the placenta and in turn study its effects on pregnancy and newborn outcomes. MethodsIn this cross-sectional study, which was conducted in the term pregnant women who underwent delivery, their placentas were collected after delivery along with the mothers' blood and cord blood. ResultsAmong the 212 pregnant women recruited, the prevalence of marginal cord insertion (MCI) in the placentas after delivery, was found to be 23% (n=48). Among these 48 cases (n=48) with MCI, 58.33% (n=28) were COVID-19 positive. The placentas with MCI had significantly lower minimum placental circumference (probability value/p value=0.04) and significantly longer umbilical cord (p-value=0.05). COVID-19 antibodies transfer from the mother to the umbilical cord (C/M antibodies ratio) was observed to be lower, albeit insignificantly. Both the weight of newborns (p value=0.03) and their COVID-19 antibodies levels (p-value =0.05) were observed to be significantly lower in the MCI group. Univariate analysis shows that a body mass index (BMI) ≥ 23 of the mothers was significantly associated with abnormal MCI. ConclusionThe prevalence of MCI was observed to be high in COVID-19-affected mothers in our study. MCI was associated with lower placental size, newborn weight, lesser transfer of COVID-19 antibodies from the mother to the fetus across the umbilical cord, and lower antibody levels in the cord blood when compared to maternal blood.

“…In contrast, the current study found a higher prevalence of ACI than a study conducted in India (2.0%). 10 It is likely that the higher prevalence in the current study compared to the Indian study is due to a disparity in the study participants’ range. The Indian research excluded mothers with chronic illnesses, which may raise the risk of ACI.…”

Introduction Anomalous cord insertion causes bad pregnancy outcomes. Therefore, knowledge on the prevalence and risk factors of anomalous cord insertion will reinforce the prenatal care by health providers in addressing the adverse outcome caused by this abnormality. Methods and Materials An institution-based cross-sectional study design was conducted among 421 singleton births at the University of Gondar comprehensive specialized hospital. A systematic random sampling technique was used to select study participants. Data were collected by using a structured questionnaire and checklist and was entered into epi-data version 3.1 and then exported to SPSS version 20 for data cleansing and analysis. Bi-variable and multivariable logistic regression was employed to identify factors associated with anomalous cord insertions. Crude and adjusted odds ratio with a 95% confidence interval was calculated to identify the independent risk factors for anomalous cord insertions. Results The prevalence of anomalous cord insertion was 9.0% in singleton pregnancies. Independent risk factors for ACI were advanced maternal age (AOR= 4.77), primiparity (AOR=3.87), maternal chronic hypertension (AOR=3.23), previous caesarian delivery (AOR=3.28), and use of IUCD before pregnancy (AOR=3.91). Conclusion Anomalous cord insertion was reported in approximately one-tenth of singleton deliveries in the representative Ethiopian population. Advanced age, primiparity, hypertensive disorder, history of caesarian section, and IUCD usage before pregnancy were associated with increased risk of anomalous cord insertion.
