The Role of Preterm Placental Calcification in High-Risk Pregnancy as a Predictor of Poor Uteroplacental Flow and Adverse Pregnancy Outcome

High-risk pregnancy is the probability of adverse pregnancy outcome is increased over the general pregnant population. Some high-risk pregnancy is the result of a medical condition present before pregnancy. In other cases, a medical condition that develops during pregnancy causes a pregnancy to become high risk. The reason why high-risk pregnancy is important is detecting the risk factors for high risk pregnancy early and preventing the complicated pregnancy. Korean society of Obstetrics and Gynecology (KSOG) announced the classification of high-risk pregnancy including 95 risk factors: obstetrics risk factors, medical risk factors, physical risk factors and risk factors of current pregnancy. However, this announcement of high-risk pregnancy by KSOG was limited for maternal-fetal healthcare providers to apply their working and making policy. First this didn't include the conception of the complicated pregnancy and high-risk delivery. Second this did not separate the risk factors depend on before and during pregnancy. This review briefly evaluates the classification of high-risk pregnancy by KSOG and suggest the new classification including the complicated pregnancy and high-risk delivery for maternal-fetal healthcare providers.

A Prospective Study

This was a prospective study conducted in pregnant patients with high risk factors who got admitted in the Department of Obstetrics and Gynaecology at Care Hospital, Jamnagar during the period from May 2018 to September 2020. Background: High-risk pregnancies causes many adverse perinatal outcomes. Doppler ultrasound is a non-invasive technique to study the feto-maternal circulation to guide the clinical management. Objective: This study aims at evaluating the role of colour Doppler in high-risk pregnancies and their perinatal outcome. Materials and Methods: This was a prospective study carried out for 29 months in the Department of Radiology with antenatal women in the age group of 18-35 years with singleton pregnancy of gestational age of <28 weeks to >35 weeks having high-risk factors considered in study. The risk factors considered were pregnancy induced hypertension (PIH), gestational diabetes, anemia, oligohydramnios, polyhydramnios and IUGR. Doppler study of umbilical artery and fetal middle cerebral artery (MCA) arteries was done and amniotic fluid index (AFI) was measured. Parameters in the form of resistive index, pulsatility index, and systolic/diastolic ratio were taken. obstetric history was taken with regular interval follow up. Results: The study was carried out with 50 patients. High-risk pregnancy was more common in the age group of 21-25 years. The most common high-risk factor in pregnancy was oligohydramnios which accounted for 30% of cases. Out of 50 high-risk pregnancies, 5 (10 %) of cases resulted in intrauterine growth restriction (IUGR). Out of 50 high-risk cases, in 36 cases, umbilical artery findings were abnormal. 3 patients had intrauterine death (IUD) and 27 patients had poor perinatal outcome. Umbilical artery abnormality showed significant sensitivity and negative predictive value for adverse (poor + IUD) perinatal. Correlation was seen between high risk pregnancy and need of emergency caesarean section and induction and associated adverse perinatal outcome. Conclusion: Combination of different arterial waveform study enhance the diagnostic accuracy in identifying those intrauterine growth restricted foetuses that were at risk. Keywords: Colour Doppler, high risk pregnancy, perinatal outcome.

Background: Congenital heart diseases (CHD) is the second leading cause of death in infancy and childhood. So the purpose of this study to know socio-demographic profile and the maternal risk factors affecting CHD, and the role of RBSK in screening with respect to CHD.Methods: A cross-sectional study was conducted during June to October 2016 in Ahmedabad city. Parents of 169 children with CHD who were beneficiaries of RBSK during the previous 3 months were interviewed.Results: The majority of children were in the age group of 0-3 years 49.7% (mean±SD= 4.26±4). Majority of families belonged to the lower middle class IV (41.4%). 44% of mothers had primary education. Mothers with age >30 yrs were 55.6%. Only 30.9% of mothers had taken folic acid during the periconceptional period. Mothers with previous adverse pregnancy outcome were 40.2%. Maternal stress and high blood pressure were present in 33.7% and 24.8% of the mothers respectively. 48% of children were diagnosed through Rashtriya Bal Swasthya Karyakram (RBSK).Conclusions: Lower middle class, lower maternal education, advanced maternal age, low folic acid intake, previous adverse pregnancy outcome, maternal stress and high blood pressure were the leading risk factors for CHD. RBSK is playing important role in screening and diagnosing of patients.

Doppler Indices

Background: The uterine artery Doppler has potentials for screening for complications of impaired placentation. The purpose of study was to assess the role of uterine artery color Doppler waveform analysis in second trimester for the prediction of preeclampsia in a high-risk pregnancy between 18-24 weeks of gestation.Methods: 100 women with moderate or high-risk factors for developing preeclampsia reporting to Obstetrics and Gynaecology department of Government Medical College and Hospital, Sector 32, Chandigarh were enrolled for present study. Transabdominal uterine artery doppler measurements was done at 18-24weeks of gestation in these patients. Doppler . The Doppler indices generated automatically from the machine , the Pulsatility Index (PI), Resistance Index (RI) , presence or absence of diastolic notch and S/D Ratio were recorded, and average was calculated.Results: Out of 100 patients there were 46 primigravidas with no additional risk factors, 22 pateints with two or more risk factors and there were no patients who had three or more risk factors in present study population. Preeclampsia is seen more commonly in primigravida and primigravida is considered as moderate risk factor for preeclampsia. It was found that an elevated second trimester uterine artery RI was significantly associated with developing preeclampsia later in pregnancy. The sensitivity and specificity of uterine artery Doppler velocimetry were found to be 84% and 55% respectively. Receiver operator characteristics (ROC) curves were created to demonstrate the prognostic value of RI and PI of uterine artery doppler indices at 18-24 weeks of gestation for the development preeclampsia. In addition, there were statistically significant positive correlations between mean RI of uterine artery doppler study and patients who developed preeclampsia. With a sensitivity of 84.21% it could identify 31% of the cases of preeclampsia at a false positive rate of 44.4%.Conclusions: Uterine artery doppler study can be used as a predictor of moderate strength for preeclampsia.
