Objective: This narrative review was performed to evaluate the correct timing of umbilical cord clamping for term infants. It was intended to determine any advantages or disadvantages from early or delayed cord clamping for newborns, infants or mothers. Methods: A systematic search on two databases was conducted using the PICO pattern to define a wide search. Out of 43 trials, 12 were included in this review. Three of the included studies are meta-analyses, nine are randomized controlled trials. Results: Early or delayed cord clamping was defined differently in all the included trials. However, there are many advantages from delayed cord clamping of at least > 60 s for newborns and infants up to 12 months of age. The trials showed no disadvantages for newborns or mothers from delayed cord clamping, except for a lightly increased risk of jaundice or the need for phototherapy. Conclusion: Delayed umbilical cord clamping for term infants should be performed. Further research is needed to improve knowledge on physiological timing of umbilical cord clamping in term infants, which also leads to the same advantages as delayed cord clamping.

Purpose: The purpose of this study was to describe sociodemographic variations in client preference for birthplace and relationships to perinatal health outcomes. Methods: Descriptive data analysis (raw number, percentages, and means) showed that preference for birthplace varied across racial and ethnic categories as well as sociodemographic categories including educational status, body mass index, payer status, marital status, and gravidity. A subsample of medically low-risk childbearing people, qualified for birth center admission in labor, was analyzed to assess variations in maternal and newborn outcomes by site of first admission in labor. Results: While overall clinical outcomes exceeded national benchmarks across all places of admission in the sample, disparities were noted including higher cesarean birth rates among Black and Hispanic people. This variation was larger within the population of people who preferred to be admitted to the hospital in labor in the absence of medical indication. Conclusion: This study supports that the birth center model provides safe delivery care across the intersections of US sociodemographics. Findings from this study highlight the importance of increased access and choice in place of birth for improving health equity, including decreasing cesarean birth and increasing breastfeeding initiation.

Gestational diabetes mellitus (GDM) is one of the most common complication of pregnancy and can lead to significant perinatal mortalities as well as long term risk of comorbidities for both mother and her offspring. This systematic review aimed to explore whether combined diet and exercise interventions are associated with improved glycemic control and/or improved maternal and newborn outcomes in women with GDM when compared to dietary interventions. A search on combined diet and exercise interventions during pregnancy in women with GDM was performed in 3 electronic databases: PubMed (NCBI), ScienceDierct, and the Cochrane Library. Evaluated outcomes were fasting blood glucose levels, postprandial blood glucose levels, glycated hemoglobin percentages, total weight gain during pregnancy, proportion of caesarean delivery, proportion of patients needing insulin, neonatal birth weight, proportion of macrosomia, neonatal hypoglycemia, and preterm birth. This systematic review identified eight randomized, controlled trials involving 592 pregnant women and 350 infants. The risk of bias of the included trials ranged from high to low. The combined diet and exercise interventions reduced fasting and postprandial blood glucose levels when compared to dietary interventions. No significant differences were reported in the selected trials regarding total weight gain during pregnancy, cesarean section, neonatal birth weight, macrosomia, neonatal hypoglycemia, and preterm birth between diet plus exercise and diet groups. The combination of diet and exercise interventions help to control postprandial blood glucose concentration in women diagnosed with GDM, but did not change either maternal or newborn outcomes.

Objective: The aim of our study is to analyze and compare obstetric, maternal and fetal outcomes of the cases who delivered with the diagnoses of early-onset and late-onset preeclampsia. Methods: The data of 149 patients with preeclampsia who delivered between January 2013 and August 2017 were collected and analyzed at Derince Training and Research Hospital. Of the cases, 65 were established with the diagnosis of early-onset preeclampsia and 84 were established with the diagnosis of late-onset preeclampsia. The demographic characteristics, biochemical changes, and perinatal, maternal and obstetric outcomes of both groups were compared. Results: Between the patient groups with early-onset and late-onset preeclampsia, there was no statistically significant difference in terms of age, gravida, parity, systolic and diastolic blood pressures, laboratory values (liver function tests, hemogram, thrombocyte count), and delivery types (p>0.05). There was statistically significant difference between serum creatinine values (p=0.045). There was statistically significant difference between two groups against early-onset preeclampsia in terms of newborn weight, low birth weight infant, newborn's need for intensive care, maternal complication and intrauterine death (p<0.001). Conclusion: Our data show that the rates of perinatal and maternal complications are higher in the patients with early-onset preeclampsia. We believe that using new predictive biomarkers is necessary for early diagnosis and labor decision in women with preeclampsia diagnosis. Considering the genetic factors and racial and ethnic differences, multi-centered studies are needed to evaluate preeclampsiarelated maternal and fetal complications. [ABSTRACT FROM AUTHOR]

• Hepatitis B association with maternal and neonatal complications remains unclear. • Three good quality studies revealed that hepatitis B can cause adverse outcomes. • Larger, more robust, well-designed prospective cohort studies are needed. The association between hepatitis B virus (HBV) infection and maternal, obstetric and newborn outcomes remains controversial, as previous studies have reported conflicting and inconsistent results on the matter. The aim was to investigate whether HBV infection increases the risk of maternal, obstetric and newborn complications. We conducted a systematic literature review, according to PRISMA statement guidelines. Studies were eligible for inclusion if they were observational cohort, case-control or cross-sectional studies, comparing maternal, obstetric or newborn complications in HBV-infected and uninfected pregnant women. PubMed was searched for published literature in English, with no date restrictions, using combinations of keywords. The titles and abstracts were independently screened for eligibility by three authors. Two authors assessed the quality of each included study and no meta-analysis was performed. We retrieved 275 records and included 15 papers. The methodological and statistical heterogeneity as well as a great variation on the types of maternal, obstetric and newborn complications studied did not allow quantitative analysis of results and conclusions about the level of evidence. Seven studies are of good quality, which makes their results more reliable. Three of them revealed that maternal HBV infection increased the risk of miscarriage, preterm birth, pregnancy-induced hypertension, fetal distress and macrosomia. These three studies were performed in China and the one with the largest number of participants only included women from rural areas. Larger, more robust, well-designed prospective cohort studies are needed. These must include adjusted estimates for confounding factors, such as other possible complications determinants, like the antenatal care quality. [ABSTRACT FROM AUTHOR]

Objective: The aims of this study were evaluation of the association of reduced fetal movements (RFM) and small-for-gestational-age (SGA) birth at term and to explore if fetal and maternal outcomes are different with single vs repeated episodes of RFM and normal fetal assessment test results.Study Design: This was a retrospective cohort study of all singleton pregnancies referred for RFMs at a tertiary fetal medicine unit from January 2008 through September 2014. Ultrasound and Doppler indices were obtained from a computerized ultrasound database and pregnancy outcome was collected from hospital records.Results: Of the 21,944 women with a singleton pregnancy booked for maternity care during the study period, 1234 women (5.62%) reported RFMs >36+0 weeks. Of these, 1029 women (83.4%) reported a single episode of RFM and 205 (16.6%) had ≥2 presentations for RFM. Women with repeated RFMs had a significantly higher mean uterine artery pulsatility index in the second trimester. The prevalence of SGA baby at birth in women presenting with a single episode as compared to repeated episodes of RFM was 9.8% and 44.2%, respectively (odds ratio, 7.3; 95% confidence interval, 5.1-10.4; P < .05).Conclusion: Repeated episodes of RFMs at term are more likely to occur in women with high second-trimester uterine artery Doppler resistance indices and are strongly associated with the birth of SGA infants. Women presenting with repeated episodes of RFM should be treated as being at high risk of placental dysfunction irrespective of the results of prenatal ultrasound and Doppler assessment.
