RESUMO
OBJECTIVE: To characterize obstetric outcomes and the association with umbilical cord (UC) complications among women complaining of reduced fetal movements (RFMs). METHODS: This retrospective cohort compared women with a perception of RFMs within 2 weeks prior to delivery with women who reported no changes in fetal movements in terms of maternal characteristics and neonatal outcomes. A primary outcome of UC complications at delivery was defined. Multivariable regression analysis was performed to identify independent associations with RFMs and UC complications. RESULTS: In all, 46 103 women were included, 2591 (5.6%) of whom reported RFMs and 43 512 (94.4%) in the control group. Compared with controls, the RFM group was more likely to be nulliparous (42.6% vs 32.2%, P < 0.001), smokers (6.4% vs 5.4%, P = 0.029), or obese (body mass index >30) (16.4% vs 11.6%, P < 0.001). They were also more likely to have an anterior placenta (56.2% vs 51.8%, P < 0.001) and poly/oligohydramnios (0.7% vs 0.4%, P = 0.015 and 3.6% vs 2.1%, P < 0.001, respectively). Induction of labor was more common in the RFM group (33.9% vs 19.7%, P < 0.001), as well as meconium (16.8% vs 15.0%, P = 0.026) and vacuum extractions (10.1% vs 8.0%, P < 0.001). Higher rates of stillbirth and the severe composite neonatal outcome were observed in the RFM group (1.5% vs 0.2%, P < 0.001 and 0.6% vs 0.3%, P = 0.010, respectively). The RFM group was characterized by higher rates of triple nuchal cord (P = 0.015), UC around body or neck (32.2% vs 29.6%, P = 0.010), and true knot (2.3% vs 1.4%, P = 0.002). Multivariable logistic regression found RFMs to be independently associated with triple nuchal cord and with a true cord knot. A sub-analysis including only cases of stillbirth (n = 127) revealed even higher rates of UC complications: 7% of all stillbirths presented with a true cord knot (20% true knots were found in stillbirths preceded by RFMs vs 6.1% in stillbirth cases without RFMs). Additionally, 33.8% of all stillbirths presented with nuchal cord (40% preceded by RFMs vs 33.3% without RFMs). CONCLUSIONS: RFMs are associated with increased risk of UC complications observed at delivery, as well as increased risk of stillbirth and neonatal adverse outcomes.

OBJECTIVE: Current data on the role of the umbilical cord in pregnancy complications are conflicting; estimates of the proportion of stillbirths due to cord problems range from 3.4 to 26.7%. A systematic review and meta-analysis were undertaken to determine which umbilical cord abnormalities are associated with stillbirth and related adverse pregnancy outcomes. METHODS: MEDLINE, EMBASE, CINAHL and Google Scholar were searched from 1960 to present day. Reference lists of included studies and grey literature were also searched. Cohort, cross-sectional, or case-control studies of singleton pregnancies after 20 weeks' gestation that reported the frequency of umbilical cord characteristics or cord abnormalities and their relationship to stillbirth or other adverse outcomes were included. Quality of included studies was assessed using NIH quality assessment tools. Analyses were performed in STATA. RESULTS: This review included 145 studies. Nuchal cords were present in 22% of births (95% CI 19, 25); multiple loops of cord were present in 4% (95% CI 3, 5) and true knots of the cord in 1% (95% CI 0, 1) of births. There was no evidence for an association between stillbirth and any nuchal cord (OR 1.11, 95% CI 0.62, 1.98). Comparing multiple loops of nuchal cord to single loops or no loop gave an OR of 2.36 (95% CI 0.99, 5.62). We were not able to look at the effect of tight or loose nuchal loops. The likelihood of stillbirth was significantly higher with a true cord knot (OR 4.65, 95% CI 2.09, 10.37). CONCLUSIONS: True umbilical cord knots are associated with increased risk of stillbirth; the incidence of stillbirth is higher with multiple nuchal loops compared to single nuchal cords. No studies reported the combined effects of multiple umbilical cord abnormalities. Our analyses suggest specific avenues for future research.

BACKGROUND: It is crucial to interpret fetal heart rate patterns with a focus on the pattern evolution during labor to estimate the relationship between cerebral palsy and delivery. However, nationwide data are not available. OBJECTIVE: The aim of our study was to demonstrate the features of fetal heart rate pattern evolution and estimate the timing of fetal brain injury during labor in cerebral palsy cases. STUDY DESIGN: In this longitudinal study, 1069 consecutive intrapartum fetal heart rate strips from infants with severe cerebral palsy at or beyond 34 weeks of gestation, were analyzed. They were categorized as follows: (1) continuous bradycardia (Bradycardia), (2) persistently nonreassuring, (3) reassuring-prolonged deceleration, (4) Hon's pattern, and (5) persistently reassuring. The clinical factors underlying cerebral palsy in each group were assessed. RESULTS: Hypoxic brain injury during labor (those in the reassuring-prolonged deceleration and Hon's pattern groups) accounted for 31.5% of severe cerebral palsy cases and at least 30% of those developed during the antenatal period. Of the 1069 cases, 7.86% were classified as continuous bradycardia (n=84), 21.7% as persistently nonreassuring (n=232), 15.6% as reassuring-prolonged deceleration (n=167), 15.9% as Hon's pattern (n=170), 19.8% as persistently reassuring (n=212), and 19.1% were unclassified (n=204). The overall interobserver agreement was moderate (kappa 0.59). Placental abruption was the most common cause (31.9%) of cerebral palsy, accounting for almost 90% of cases in the continuous bradycardia group (64 of 73). Among the cases in the Hon's pattern group (n=67), umbilical cord abnormalities were the most common clinical factor for cerebral palsy development (29.9%), followed by placental abruption (20.9%), and inappropriate operative vaginal delivery (13.4%). CONCLUSION: Intrapartum hypoxic brain injury accounted for approximately 30% of severe cerebral palsy cases, whereas a substantial proportion of the cases were suspected to have either a prenatal or postnatal onset. Up to 16% of cerebral palsy cases may be preventable by placing a greater focus on the earlier changes seen in the Hon's fetal heart rate progression.

The purpose of the present systematic review is to summarize current data concerning the impact of umbilical cord entanglement on adverse pregnancy outcomes. We used the Medline, Scopus, EMBASE, Cochrane Central Register of Controlled Trials CENTRAL and Google Scholar databases. We selected all observational (both prospective and retrospective) studies for inclusion. Meta-analysis of the risk ratios (RR) was performed with RevMan 5.3 software. Univariate meta-regression and leave-one-out meta-analysis was performed with Open Meta-Analyst statistical software. Trial sequential analysis was performed with the TSA software. Overall, twenty studies were included in the present study with 267,233 pregnant women (50.103 with cord entanglement and 217,130 controls). An increased risk of neonatal Apgar score <7 at the first minute of life was observed among cases with cord entanglement (RR = 1.75, 95% CI 1.46, 2.11). Fetal distress was significantly higher in the entanglement group (RR 1.50, 95% CI 1.33, 1.69). The incidence of fetal pH < 7.1 was also significantly higher in the entanglement group (RR 1.73, 95% CI 1.48, 2.03). Adequate power was observed in all investigated outcomes of our primary analysis after evaluating the results of the TSA analysis. Prediction intervals designated that future studies were likely to report increased risk of low Apgar score at the first minute of life, increased risk of fetal distress as well as of observing a fetal pH < 7.1. Concluding, the findings of this systematic review suggest that there is sufficient evidence to support the involvement of cord entanglement to adverse neonatal perinatal outcomes.

BACKGROUND: Nuchal cord is a common finding in pregnancy. It is unclear whether a nuchal cord at birth causes birth asphyxia and raises the risk for developing cerebral palsy of the offspring. AIM: To evaluate the incidence of cerebral palsy in children born with and without nuchal cord. STUDY DESIGN: A population-based cohort analysis including all singleton deliveries over >20â¯years at a single tertiary medical center was conducted. The incidence of cerebral palsy in children up to 18â¯years of age was evaluated. Kaplan-Meier survival curve was used to compare cumulative incidence between the groups, and a Cox proportional hazards model was used to control for confounders. RESULTS: During the study period, 243,682 singleton deliveries met the inclusion criteria. Of them, 14.1% (nâ¯=â¯34,332) were diagnosed with nuchal cord at birth. Rates of cerebral palsy were comparable between the groups (0.1% vs. 0.1%, ORâ¯=â¯1.03, 95% CI 0.69-1.52, pâ¯=â¯0.89). The Kaplan-Meier survival curve demonstrated no significant differences in cumulative incidence of cerebral palsy for children born with or without nuchal cord (log rank pâ¯=â¯0.92, Fig. 1). The Cox proportional hazards model, controlled for preterm delivery, maternal age, diabetes and hypertensive disorders, showed no association between nuchal cord and cerebral palsy (adjusted HRâ¯=â¯1.06; 95% CI 0.71-1.57; pâ¯=â¯0.77). CONCLUSION: In our population, nuchal cord at birth was not associated with higher risk for cerebral palsy.

OBJECTIVE: To identify nuchal cord risk factors. METHODS: The present case-control study was carried out between December 2016 and April 2017 at two hospitals in Yaoundé, Cameroon. Singletons with a nuchal cord at delivery (case group) as well as the two neonates without a nuchal cord delivered immediately after each case (control group), all in cephalic presentation, were included. Undated pregnancies were excluded. The main variables studied were maternal age, parity, pregnancy duration at delivery, cord insertion site, cord length, delivery weight, and fetal sex. RESULTS: A nuchal cord was present in 121 (6.0%) of 2015 singletons. The final analysis included 114 and 228 neonates in the case and control groups, respectively, with similar maternal age, parity, pregnancy duration, and delivery weight. Significant independent risk factors for nuchal cord formation were a cord length of 70 cm or more (adjusted odds ratio [aOR] 19.10, 95% confidence interval [CI] 8.63-42.04), a pregnancy duration of more than 42 weeks (aOR 7.43, 95% CI 1.46-37.21), marginal cord insertion (aOR 2.90, 95% CI 1.11-9.35), and a male fetus (aOR 2.14, 95% CI 1.16-7.74). CONCLUSION: Marginal cord insertion and post-term pregnancy should be added to the list of known nuchal cord risk factors.

INTRODUCTION: Main objective of the present study was to investigate the association between the presence of nuchal cord (NC) and the measurement of the ductus venosus pulsatility index for veins (ductus venosus (DV) PIV). METHODS: This was a prospective study of 1974 singleton pregnancies that underwent first-trimester screening at 11-13+6 gestational weeks. Color Doppler was used to demonstrate the presence of a NC in all cases and the DV PIV was calculated routinely, as part of the standard scan. The association between the presence of a NC and the DV PIV was then examined overall and at each gestational week. RESULTS: A NC was demonstrated in 17.1% of cases. The incidence of nuchal cord was significantly higher at 13-13+6 weeks (24.7%, n = 119) compared to the one at 12-12+6 (16.5%, n = 192) and 11-11+6 weeks (7.9%, n = 26) (p < .001). No significant correlation was found between NC presence and DV PIV (p = .344). The DV PIV was 0.99 (± 0.15) for patients without NC versus 0.99 (± 0.15) for patients with NC (p = .34). CONCLUSIONS: There was no association between the presence of a NC at 11-13+6 gestational weeks and the DV PIV.

Neonaticide is a serious allegation that needs a complete chain of criminal investigations. In this context, a nuchal cord is considered to be responsible for an infant's death, but there is a clear lack of evidence. The purpose of our study is to reveal if a nuchal cord can be responsible for stillbirth, poor perinatal outcome, or neonatal death in the forensic aspect. We conducted a prospective study in collaboration with the Augustinian Sisters' Hospital in Cologne, Germany in the period from February 2014 to May 2016. Four-hundred eighty-six children were enrolled. All births were assessed regarding the occurrence of an umbilical cord entanglement, and perinatal outcome was measured by arterial blood gas analysis, Apgar after 1, 5, and 10 min after birth as well as the general vitality. The prevalence of a nuchal cord was 16.87%. Apgar decrease and acidosis were significantly associated with a nuchal cord. No adverse perinatal outcome was recorded in this constellation. There was no child death regarding the first 24 h, and no mother experienced a syncope while giving birth. We can conclude that a nuchal cord is not associated with adverse perinatal outcome.

PURPOSE: Meconium-stained amniotic fluid (MSAF) is rarely observed in preterm pregnancies, and its clinical significance is undetermined. We evaluated the correlation between MSAF and obstetrical and perinatal complications prior to 34 weeks' gestation. MATERIALS AND METHODS: Pregnancies complicated with MSAF between 24 and 34 weeks of gestation were compared with same gestational age-matched controls. The variables measured were: obstetrical complications: clinical chorioamnionitis, Intrahepatic Cohlestasis of Pregnancy - ICP, Intra Uterine Growth Restriction - IUGR, preeclampsia, gestational diabetes; nonobstetrical complications; and perinatal complications: cord around neck/body, Apgar <7 at 5 min, cord pH, Neonatal Intensive Care Unit - NICU admission, complications during NICU hospitalization, and composite outcome. RESULTS: Higher incidence of clinical chorioamnionitis (15% versus 4.3%; p = 0.041) and higher incidence of cord around the neck/body were found in the MSAF group in comparison with the clear AF group (27.4% versus 18.4%; p = 0.04). No significant differences between the study's groups were found in nonobstetrical complications or other perinatal complications investigated in our study. CONCLUSION: MSAF in preterm pregnancy is an ominous sign for the occurrence of chorioamnionitis and for in utero cord compression. Therefore, MSAF in preterm pregnancies should be considered as a non-reassuring sign.

OBJECTIVES: To study the occurrence of cords accident (nuchal cords, prolapse, and braces) after external cephalic version according to its failure or success. METHODS: Retrospective study between 1998-2015 comparing in the cord accident diagnosed at delivery (by midwife or doctors according to mode of delivery): Patients with attempt ECV: Group 1 cephalic presentation after successful ECV with trial of labor, and Group 2 failed ECV followed by elective cesarean or trial of labor. Patients with no attempt ECV Group 3 spontaneous cephalic presentation matching for delivery date, maternal age, parity, body mass index, and delivery history with group 1, Group 4 Breech presentation without attempt ECV with trial of labor. RESULTS: A total of 776 women with breech presentation were included (198 in group 1, 446 in group 2, 396 in group 3 and 118 in group 4). The prevalence of cord accident did not differ according to ECV attempt (17.08 % versus 18.9 %), to cephalic presentation (group 1: 24.7 % versus group 3: 25 %) and to breech presentation (group 2: 16.9 % versus group 4: 17.2 %). The trial of labor after failed ECV did not increase the risk of cord accident when compared with elective cesarean (17.4 % versus 16 %). A prolapse cord was only observed after trial of labor, i.e. in groups 1, 2 and 4 without difference (respectively 1, 0.8 and 1.7 %). In each group, the rate of cesarean was not different according to the presence of nuchal cord. CONCLUSION: Success or failed External cephalic version is not associated with an increased risk of cord accident.

OBJECTIVE: To evaluate the relationship between entanglement of umbilical cord around the fetal neck and adverse perinatal outcomes. METHODS: In this prospective cohort study, perinatal outcomes of 218 pregnancies complicated with nuchal cord (NC) (study group) were compared with 190 uncomplicated pregnancies (control group). Main outcome measures were umbilical cord pH values, APGAR scores and cesarean section (C/S) rates. Fetal distress was stated as an abnormal heart rate pattern on electronic fetal heart monitorization. RESULTS: There were no statistically significant differences in maternal demographic and obstetric features, between groups. There were no statistically significant differences regarding C/S rates between groups, even though fetal distress was significantly the leading indication for cesarean delivery, in the study group (p = 0.021). The number of entanglement was significantly related with fetal distress (p < 0.001). There were no statistically significant differences in umbilical cord gas values, one-minute and five-minute APGAR scores between the groups. Furthermore, there was a significant male dominance in the study group (p = 0.014) and also, amniotic fluid indexes (AFI) were significantly higher in this group (p = 0.002). CONCLUSION: This study demonstrated that, entanglement of umbilical cord around the fetal neck or NC is not related with adverse perinatal outcomes such as acidosis and low APGAR scores. So that, a targeted care on NC via ultrasound during labor, is not an essential part of the examination.

PURPOSE: Birth asphyxia leading to acidosis comprises 20-60 % of perinatal mortality. Nuchal cord (NC) is one of the possible causes of birth asphyxia. Majority of fetuses who are antenatally detected to have nuchal cord are able to achieve successful vaginal birth. The purpose of this study was to analyze the effect of nuchal cord on fetal acid base status and perinatal outcome in vaginal deliveries. STUDY DESIGN: 150 parturients were equally divided into three groups after vaginal delivery based on no NC, single and multiple loops. Umbilical cord arterial blood was analyzed for biochemical markers i.e. pH, PO2, SPO2, PCO2, HCO3 (-), standard base excess and lactate for acidosis. Labor complications like abnormal FHR, meconium-stained liquor, prolonged second stage, instrumental vaginal delivery, third stage complications were compared. In neonates, birth weight, Apgar score ≤7 at 5 min, NICU admission and other morbidity and mortality during hospital stay were compared among groups using suitable statistical tests. Above parameters were also compared between tight and loose loops. RESULT: Nuchal cord groups had significantly higher frequency of labor complications than no NC group, especially tight loops. Neonates with NC had significantly higher frequency of meconium-stained liquor, Apgar score ≤7 at 5 min, deranged biochemical markers, NICU transfer. However, none of the neonate had pH in acidosis range and majority were discharged in healthy condition. CONCLUSION: Patients with NC are likely to have uneventful labor and delivery as cord compression is transient and most fetuses are able to compensate for reduce umbilical blood flow. Routine antenatal ultrasound scan is not advisable, as mode of delivery and labor management does not change with detection of NC antenatally. Therefore, vaginal delivery with routine labor protocol can be allowed in cases of nuchal cord.

Many types of early life events can cause cerebral dysfunction; however, not all children have medical records or neurologic imaging documenting brain injuries. Rather, many neuropsychologists base their findings on caregiver reports describing possible early brain insults. Neuropsychological studies suggest that brief perinatal cyanosis and/or childhood neglect may negatively affect cognitive functioning. Should the mere suggestion of these events from caregiver reports be enough to suggest deficits? This study examines four groups of children: those with (1) reported nuchal cord compression with brief cyanosis, (2) reported childhood neglect, (3) reported history of both, and (4) reported history of none. It was hypothesized that based on the literature of these populations, children who present at an evaluation with the report of these insults would also present cognitive deficits. Results revealed no significant difference in intellect, memory, or academic abilities. A significant difference was shown between groups during the Wisconsin Card-Sorting Test Failure to Maintain Set, as groups with a history of neglect had lower scores. A history of childhood neglect also suggested an increased risk for subsequent emotional/behavioral diagnoses. These findings suggest that although the profiles range between low-average and average, reports of early life insults can flag potential deficits in a child's neuropsychological profile.

AIM: To clarify perinatal outcomes of monoamniotic (MM) twin pregnancies. MATERIAL AND METHODS: MM twins delivered in seven tertiary perinatal centers during the last decade were retrospectively evaluated. All pregnant women were scheduled to begin inpatient management at around 24 weeks of gestation and undergo a planned cesarean section beyond 32 weeks. Pregnancy outcomes, prevalence of fetal death and cord entanglement, perinatal mortality and neuromorbidity rate at discharge were examined. RESULTS: The study group comprised 38 MM twin pregnancies (76 fetuses). Cord entanglement was confirmed in 88% (30/34) of women, and fetal deaths occurred in nine women (eight were both fetal deaths, and one was single fetal death). The cord entanglement accounted for 65% (11/17) of the fetal deaths. The median gestational age at delivery was 31⺳ weeks, but that for viable infants was 32⺳ weeks; the median birth weight was 1642 g, the perinatal mortality rate was 2% (1/60), and the neuromorbidity rate was 8% (5/50). The overall survival rate was 75% (57/76). CONCLUSION: Perinatal outcomes in our study were relatively good irrespective of high frequency of cord entanglement. Close fetal monitoring may allow MM twin pregnancies to extend gestational age, which may contribute to reduce both fetal death and neonatal morbidity by immaturity, although the best delivery weeks remained undetermined.

With the advent of ultrasound as a means of providing quality antenatal care, there is an increase in the diagnosis of nuchal cord in fetuses. The major cause of foetal or neonatal death during labor and in postpartum period is birth asphyxia and tight nuchal cord is a cause of birth asphyxia. Whilst there are instances in which fetuses with 3 to 4 loops of cord around the neck have been delivered by normal vaginal delivery, some cases have to be delivered by caesarean section due to foetal distress caused by a single loop of cord around the neck. The reason for conducting this study was also to analyze the incidence and other aspects of nuchal cord. Dhulikhel Hospital labour registry was reviewed between Jan 2010 and Dec 2011. A total of 289 cases with at least one loop of nuchal cord were recorded as study case. For comparison, 965 controls were randomly selected from the 4219 unaffected singleton births delivered during the same time period. Of 1254 neonates, nuchal cord was present at 6.85% of deliveries (n = 289). Of these the incidence was 6.57% at preterm, 49.13% at term, 39.79% at postdated and 4.50% at postterm. A total of 151 had one loop and 138 had two or more loops. There was significant difference in the maternal age and birth weight of among three groups (control, with one loop and with two or more loops) in this study (p = 0.002) and (p = 0.000) respectively. However, the incidence was not affected by caste, parity, gestational age, antenatal site, neonatal intensive care unit admission and other perinatal complications. Most were primigravida (62.98%) and about 85.12% were delivered vaginally but caesarean section had to be done in 30 cases. And 2.8% cases required neonatal intensive care unit admission for prematurity. Obstetrician working in the periphery should refer the clients to a tertiary care center to confirm a suspicion of nuchal cord (non-engaged foetal head, decreased foetal movements, meconium stained liquor, foetal distress or malpresentation etc.) and also as a routine basis for ultrasound. Clients with confirmed complication should be managed in tertiary hospitals or institutions with the facility of ultrasound, cardiotocography and emergency surgery. This would improve the health of both the mother and fetus.

We sought to determine the incidence of cord entanglement around any part of fetal body during early gestation using three-dimensional (3D) sonography. A prospective consecutive study was designed and 3D ultrasound was performed. Two hundred thirty-seven singleton pregnancies between 13 and 16 weeks were included. Cord entanglement was defined when one or more of the following was detected: cord around neck, hand, leg, thorax, abdomen, shoulder. We considered cord entanglement when one or more loops of cord encircled any part of body. Free-floating cord through all its length in the amniotic fluid was defined as free cord. Cord entanglement was observed in 149 (62.9%) patients. Of those, 64 (42.9%) cords were entangled around necks, 23 (15.4%) around legs, 19 (12.7%) around hands, 7 (4.8%) around abdomens, 36 (24.2%) around other body parts (thorax, shoulder, and pelvis). The incidence of total cord entanglement was similar between 13 and 16 weeks' gestation and was between 60 and 65%. The incidence of early pregnancy cord entanglement was 62.9%. According to the literature, this incidence is higher in comparison to the incidence of cord entanglement later in pregnancy. Therefore, this phenomenon may be considered a part of normal early fetal development.

OBJECTIVE: to find out the incidence of nuchal cord at delivery, intrapartum complication and perinatal outcomes in the cases with nuchal cord. MATERIALS AND METHODS: A prospective, cross-sectional, comparative study done at Kathmandu Medical College Teaching Hospital (KMCTH) between March 2006 to September 2006. Total 512 deliveries occurred during this period that were enrolled in the study and were analyzed for presence of nuchal cord at the time of delivery, number of coils whether loose or tight, intrapartum complications and perinatal outcome. The cases with nuchal cord at the time of delivery were taken as study group and the cases without nuchal cord served as control group. Outcome variables between the two groups were compared. Outcome variables used were meconium staining of liquor, rate of instrumental and caesarean delivery, intrapartum fetal heart rate (FHR) irregularities. As a measure of perinatal outcome Apgar score<7 at 1 minute and 5 minutes and incidence of neonatal unit admission was taken. RESULTS: Incidence of nuchal cord at the time of delivery was 22.85%. Incidence of single nuchal cord was highest (18.95%). Intrapartum complications like FHR irregularities and meconium staining of liquor were increased in nuchal cord group but statistically not significant. Instrumental delivery rate was high in nuchal cord group but statistically not significant (0.108). However, caesarean section rate was high in the group without nuchal cord (p=0.029). Apgar score<7 at 1 minute was significantly low in nuchal cord group (p=0.010) but apgar score at 5 minutes and admission to neonatal unit was not more common. CONCLUSION: Nuchal cord is not associated with adverse perinatal outcome.
