[Factors influencing the occurrence of small for gestational age at different degrees]. / ä¸åŒç¨‹åº¦å°äºŽèƒŽé¾„å„¿å‘ç”Ÿçš„å½±å“å› ç´ åˆ†æž.

OBJECTIVES: To investigate the factors influencing the occurrence of small for gestational age (SGA) at different degrees and provide a basis for early identification of severe SGA cases. METHODS: Neonatal and maternal prenatal information were retrospectively collected from January 2018 to December 2022 at Peking University People's Hospital. The neonates were divided into three groups: severe SGA group (birth weight below the 3rd percentile for gestational age and sex), mild SGA group (birth weight ≥3rd percentile and <10th percentile), and non-SGA group (birth weight ≥10th percentile). An ordered multinomial logistic regression model was used to analyze the factors influencing the occurrence of SGA at different degrees. RESULTS: A total of 14 821 neonates were included, including 258 cases (1.74%) in the severe SGA group, 902 cases (6.09%) in the mild SGA group, and 13 661 cases (92.17%) in the non-SGA group. The proportions of preterm births and stillbirths were higher in the severe SGA group compared to the mild SGA and non-SGA groups (P<0.0125). The proportion of neonatal asphyxia was higher in both the severe SGA and mild SGA groups compared to the non-SGA group (P<0.0125). Ordered multinomial logistic regression analysis showed that maternal pre-pregnancy underweight (OR=1.838), maternal pre-pregnancy obesity (OR=3.024), in vitro fertilization-embryo transfer (OR=2.649), preeclampsia (OR=1.743), connective tissue disease during pregnancy (OR=1.795), nuchal cord (OR=1.213), oligohydramnios (OR=1.848), and intrauterine growth restriction (OR=27.691) were all associated with a higher risk of severe SGA (P<0.05). Maternal parity as a multipara (OR=0.457) was associated with a lower likelihood of severe SGA (P<0.05). CONCLUSIONS: Maternal pre-pregnancy underweight, maternal pre-pregnancy obesity, in vitro fertilization-embryo transfer, preeclampsia, connective tissue disease during pregnancy, oligohydramnios, nuchal cord, and intrauterine growth restriction are closely related to the occurrence of more severe SGA. Maternal parity as a multipara acts as a protective factor against the occurrence of severe SGA.

Are reduced fetal movements "merely" a maternal perception or truly a reflection of umbilical cord complications? A clinical trial.

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.

The Presence of a Single Nuchal Cord in the Third Trimester May Not Affect Tei Index in LGA Fetuses.

(1) Background: The aim of this study was to assess the RV (right ventricle) and LV (left ventricle) Tei index in large for gestational age (LGA) fetuses with a single 360-degree umbilical coil of the umbilical cord around the fetal neck identified by ultrasound in the third trimester of gestation. (2) Methods: The RV and LV Tei index for the cardiac function were measured in 297 singleton pregnancies, and we identified 25 LGA fetuses. There were 48% of LGA fetuses with a nuchal umbilical cord-LGA/NC-larger for gestational age fetuses with a nuchal cord. NC was detected with a color Doppler during a transverse scan of the fetal neck, when the umbilical cord formed a U shape. All fetuses had normal anatomy and normal uterine, placental, umbilical, intracardiac and cerebral Doppler waveforms values for their gestational age. (3) Results: The RV Tei index was significantly higher in the LGA subgroup vs. AGA (0.6 ± 0.2 vs. 0.50 ± 0.2; p value = 0.01), but in LGA fetuses with a single coil of the nuchal cord, there were not any significant changes in the Tei indexes. (4) Conclusions: The Tei index might not be impacted by the presence of the nuchal cord in LGA fetuses.

Percepção sobre o cuidado à perda gestacional: estudo qualitativo com casais brasileiros / Perceptions on pregnancy loss care: a qualitative study with brazilian couples / Percepción sobre la atención a la pérdida del embarazo: estudio cualitativo con parejas brasileñas

Este artigo analisou a percepção e os sentimentos de casais sobre o atendimento recebido nos serviços de saúde acessados em função de perda gestacional (óbito fetal ante e intraparto). O convite para a pesquisa foi divulgado em mídias sociais (Instagram e Facebook). Dos 66 casais que contataram a equipe, 12 participaram do estudo, cuja coleta de dados ocorreu em 2018. Os casais responderam conjuntamente a uma ficha de dados sociodemográficos e uma entrevista semiestruturada, realizada presencialmente (n=4) ou por videochamada (n=8). Os dados foram gravados em áudio e posteriormente transcritos. A Análise Temática indutiva das entrevistas identificou cinco temas: sentimento de impotência, iatrogenia vivida nos serviços, falta de cuidado em saúde mental, não reconhecimento da perda como evento com consequências emocionais negativas, e características do bom atendimento. Os achados demonstraram situações de violência, comunicação deficitária, desvalorização das perdas precoces, falta de suporte para contato com o bebê falecido e rotinas pouco humanizadas, especialmente durante a internação após a perda. Para aprimorar a assistência às famílias enlutadas, sugere-se qualificação profissional, ampliação da visibilidade do tema entre diferentes atores e reorganização dos serviços, considerando uma diretriz clínica para atenção ao luto perinatal, com destaque para o fortalecimento da inserção de equipes de saúde mental no contexto hospitalar.(AU)

This study analyzed couples' perceptions and feelings about pregnancy loss care (ante and intrapartum fetal death). A research invitation was published on social media (Instagram and Facebook) and data collection took place in 2018. Of the 66 couples who contacted the research team, 12 participated in the study by filling a sociodemographic questionnaire and answering a semi-structured interview in person (n=04) or by video call (n=08). All interviews were audio recorded, transcribed, and examined by Inductive Thematic Analysis, which identified five themes: feelings of impotence, iatrogenic experiences in health services, lack of mental health care, not recognizing pregnancy loss as an emotionally overwhelming event, and aspects of good healthcare. Analysis showed experiences of violence, poor communication, devaluation of early losses, lack of support for contact with the deceased baby, and dehumanizing routines, especially during hospitalization after loss. Professional qualification, extended pregnancy loss visibility among different stakeholders, and reorganization of health services are needed to improve the care offered to grieving families, considering a clinical guideline for perinatal grief care with emphasis on strengthening the insertion of mental health teams in the hospital context.(AU)

Caesarean delivery of a breech singleton with eight loops of nuchal cord.

Nuchal cord accidents comprise a third of stillbirths in the third trimester. These are often due to higher order nuchal cords, with more than three loops. In this report, we discuss a case of a gestation complicated by a nuchal cord with eight loops and severe fetal growth restriction, requiring expedited delivery due to non-reassuring fetal heart tones. Our case demonstrates the value of high-quality ultrasound in detecting complex nuchal cords, as well as highlighting the potentially dynamic and unstable fetal status in an affected gestation. Antenatal knowledge of nuchal cord in the setting of non-reassuring fetal status can help guide patient counselling and assist with identifying possible aetiologies. Finally, our case demonstrates that close monitoring and early intervention can prevent potentially catastrophic outcomes.

Comparison of the effectiveness and pregnancy outcomes of labor induction with dinoprostone or single-balloon catheter in term nulliparous women with borderline oligohydramnios.

BACKGROUNDS: At present, there is no consensus on the induction methods in term pregnancy with borderline oligohydramnios. This study aimed to compare the effectiveness and pregnancy outcomes of labor induction with dinoprostone or single-balloon catheter (SBC) in term nulliparous women with borderline oligohydramnios. METHODS: We conducted a retrospective cohort study from January 2016 to November 2018. During the study period, a total of 244 cases were enrolled. Of these, 103 cases were selected for induction using dinoprostone and 141 cases were selected for induction with SBC. The pregnancy outcomes between the two groups were compared. Primary outcomes were successful vaginal delivery rates. Secondary outcomes were maternal and neonatal adverse events. Multivariate logistic regression was used to assess the risk factors for vaginal delivery failure in the two groups. RESULTS: The successful vaginal delivery rates were similar between the dinoprostone group and the SBC group (64.1% [66/103] vs. 59.6%, [84/141] P = 0.475), even after adjustment for potential confounding factors (adjusted odds ratio [aOR]: 1.07, 95% confidence interval [CI]: 0.57-2.00, P = 0.835). The incidence of intra-amniotic infection was lower in the dinoprostone group than in the SBC group (1.9% [2/103] vs. 7.8%, [11/141] P < 0.001), but the presence of non-reassuring fetal heart rate was higher in the dinoprostone group than in the SBC group (12.6% [13/103] vs. 0.7%, [1/141] P < 0.001). Multivariate logistic regression showed that nuchal cord was a risk factor for vaginal delivery failure after induction with dinoprostone (aOR: 6.71, 95% CI: 1.96-22.95). There were three factors related to vaginal delivery failure after induction with SBC, namely gestational age (aOR: 1.51, 95% CI: 1.07-2.14), body mass index (BMI) >30 kg/m2 (aOR: 2.98, 95% CI: 1.10-8.02), and fetal weight >3500 g (aOR: 2.49, 95% CI: 1.12-5.50). CONCLUSIONS: Term nulliparous women with borderline oligohydramnios have similar successful vaginal delivery rates after induction with dinoprostone or SBC, with their advantages and disadvantages. In women with nuchal cord, the risk of vaginal delivery failure is increased if dinoprostone is used in the induction of labor. BMI >30 kg/m2, large gestational age, and estimated fetal weight >3500 g are risk factors for vaginal delivery failure after induction with SBC.

Outcome of pregnancies with marginal umbilical cord insertion.

PURPOSE: To evaluate the outcome of labor in cases of marginal umbilical cord insertions. MATERIAL AND METHODS: This case-control study was carried out between December 1st, 2017 and April 30th, 2018. All singletons with marginal cord insertion (MCI) and three new-borns without MCI were recruited. The main variables studied included gestational age at delivery, occurrence of preeclampsia, intrapartum haemorrhage, mode of delivery, cord insertion, cord length, birth and placenta weights, presence of nuchal cord, Apgar score and admission of the new-born into the neonatal intensive care unit (NICU). Data from both groups were compared. Fisher exact test, t-test and logistic regression were used for comparison. p < .05 was considered statistically significant. RESULTS: Our prevalence of MCI was 7.2% (85/1181). MCI was significantly associated with pre-eclampsia (aOR 2.94, 95%CI 1.14-7.59), placenta abruption (OR 33.68, 95%CI 9.80-115.76), nuchal cord entanglement (aOR 3.07, 95%CI 1.69-5.59), low birth weight (aOR 3.15, 95%CI 1.05-9.45) and transfer of the newborn to the NICU (OR 4.72, 95%CI 2.46-9.04). CONCLUSIONS: MCI is associated with increased maternal, fetal and neonatal adverse morbidities. Therefore, pregnancy with MCI should be well followed up. Moreover, the delivery should be conducted in settings where rapid intensive neonatal care can be offered.

Antenatal course and perinatal outcome after ultrasound detection of triple nuchal cord: a case series.

OBJECTIVE: To determine the antenatal course and perinatal outcome of pregnancies in which a triple nuchal cord was detected prenatally by ultrasound. METHODS: Singleton pregnancies presenting for ultrasound evaluation after 24 weeks of gestation were routinely screened for the presence of nuchal cord loops using two-dimensional and color-Doppler ultrasound. Fetuses with more than two nuchal cord loops were identified from our fetal medicine database and their ultrasound reports and medical records were reviewed. RESULTS: During the study period from July 2014 to February 2019, 10 singleton fetuses with triple nuchal cord were identified, for a prevalence of 1 in 506 or 0.2%. No cases of more than three nuchal cord loops were detected. No predisposing factors were identified. Cases detected after 36 weeks (n = 4) delivered by cesarean section after 37 weeks and the diagnosis of triple nuchal cord was confirmed in all of them. Cases detected before 36 weeks (n = 6) underwent fetal surveillance. Among these cases, the umbilical cord unraveled itself from around the fetal neck in at least one loop in 83% of these cases. Overall, eight (80%) of the neonates were delivered by cesarean section for different reasons; in only two, the sole indication for cesarean delivery was the presence of the triple nuchal cord. All the infants had a good perinatal outcome, although one newborn infant was small for gestational age. CONCLUSIONS: Ultrasound detection of triple nuchal cord during late pregnancy was associated with good perinatal outcomes. However, this prenatal finding was also associated with a high rate of cesarean section. In preterm pregnancies, multiple loops will reduce spontaneously in the majority of cases, so expectant management is indicated. In term pregnancies, the decision regarding the optimal timing and mode of delivery should be discussed with the parents taking into account the individual clinical scenarios.

Nudos verdaderos del cordón Umbilical. Presentación de tres casos. Maternidad de Ouargla. 2017-2018, Argelia / True knots of the umbilical cord. Presentation of three cases. Ouargla Maternity. 2017-2018, Argeria

Introducción: los nudos verdaderos del cordón umbilical son poco frecuentes y ocurren entre 0.3-1.3 por ciento de todos los embarazos. La tasa de mortalidad fetal antes del parto oscila entre 4 a 10 veces mayor con relación a los embarazos con cordones umbilicales normales. Presentación de caso: caso 1 paciente de 39 años de edad G3 P (1 eut y 1 ces) A0, obesa, edad gestacional de 39.3 semanas, que asiste al Hospital con contracciones uterinas de 3/10 minutos, buena intensidad, presentación alta, cefálica y la frecuencia cardiaca fetal (fcf) de 164/minutos, cesárea anterior hace 2 años, signo de más, con cuello uterino permeable 1cm, grueso y membranas intactas. Caso 2: paciente que ingresa en el Hospital con 41 años de edad, obesa, con G5 P4 A0, Edad gestacional de 40, 4 semanas, el último parto ocurrió hace 6 años, posee contracciones 2/10 minutos y fcf de 160/minutos, con desaceleraciones tardías en los registros cardiotocográficos (CTG), dilatación de 2cms con membranas intactas y el cuello grueso y rígido. TA: 140/80, en hipertensa crónica y tratamiento con metildopa 250mg c/6hrs. Caso 3: paciente que ingresa con 39 años de edad, 41 semanas de gestación, G6 P5 A0, obesa, el último parto se realizó con la aplicación de fórceps con apgar bajo, hace 3 años, lleva tratamiento con metildopa 500mg cada 8 horas por ser una hipertensa crónica; ingresó con tensión arterial de 120/80, se queja de dolores bajo vientre. Discusión: dentro de los factores de riesgos planteados en la aparición de los nudos verdaderos del cordón umbilical se constató: la hipertensión arterial crónica en los tres pacientes, dos multíparas, tres con edad igual o mayor a 39 años y todos con cordones mayores a 60cms. La longitud normal del cordón es de (30cms a 60cms). Se plantea como riesgo de desarrollar nudos del cordón, con cordones mayores a 80cms. Conclusiones: no hubo complicaciones para la salud de los neonatos(AU)

Introduction: true umbilical cord knots are rare and occur between 0.3-1.3 percent of all pregnancies. The fetal mortality rate before delivery ranges from 4 to 10 times higher than in pregnancies with normal umbilical cords. Case presentation: case 1 39-year-old patient G3 P (1 eut and 1 ces) A0, obese, gestational age of 39.3 weeks, who attends the Hospital with uterine contractions of 3/10 minutes, good intensity, high presentation, cephalic and fetal heart rate (fcf) of 164/min, previous cesarean section 2 years ago, plus sign, with a patent cervix 1cm, thick and intact membranes. Case 2: patient admitted to the Hospital at 41 years of age, obese, with G5 P4 A0, gestational age of 40, 4 weeks, the last delivery occurred 6 years ago, has contractions 2/10 minutes and fcf of 160/minutes, with late decelerations in the cardiotocographic recordings (CTG), dilation of 2 cm with intact membranes and a thick and stiff neck. BP: 140/80, in chronic hypertensive and treatment with methyldopa 250mg every 6hrs. Case 3: patient who was admitted with 39 years of age, 41 weeks of gestation, G6 P5 A0, obese, the last delivery was performed with the application of forceps with low apgar, 3 years ago, has been treated with methyldopa 500mg every 8 hours for be a chronic hypertensive; she was admitted with a blood pressure of 120/80, she complains of pain in the lower abdomen. Discussion: among the risk factors raised in the appearance of true umbilical cord knots, it was found: chronic arterial hypertension in the three patients, two multiparous, three with age equal to or greater than 39 years and all with cords greater than 60 cm. The normal length of the cord is (30cms to 60cms). It is posed as a risk of developing knots in the cord, with cords greater than. Conclusions: there were no complications for the health of the neonates(EU)

Umbilical cord characteristics and their association with adverse pregnancy outcomes: A systematic review and meta-analysis.

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.

Fetal heart rate pattern in term or near-term cerebral palsy: a nationwide cohort study.

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.

Impact of nuchal cord on antenatal and intrapartum foetal heart rate surveillance and perinatal outcome.

Analysing antepartum and intrapartum computerised cardiotocographic (cCTG) parameters in physiological term pregnancies with nuchal (NC) or body cord (BC), in order to correlate them with labour events and neonatal outcome. We enrolled 808 pregnant women, composed of 264 with 'one NC', 121 with 'multiple NCs', 39 with BC and 384 with 'no NC', were monitored from the 37th week of gestation before labour, while 49 pregnant women with 'one or more NCs' and 47 with 'no NCs' were analysed during labour. No differences in maternal characteristics, foetal pH at birth and 5-min Apgar score were observed. The birth weight was significantly lower in the 'multiple NCs' group, while 1-minute Apgar score was lower in the BC group than the other groups, respectively. No relevant differences in cCTG parameters were observed, except for LTI, Delta and number of variable decelerations in antepartum period and only variable deceleration in intrapartum period.Impact statementWhat is already known on this subject? Ultrasound cannot predict which foetuses with NCs are likely to have problem during labour. The question arose if single or multiple NC could affects FHR monitoring prior and during labour.What do the results of this study add? Computerised cardiotocography (cCTG) is a standardised method developed to reduce inter- and intra-observer variability and the poor reproducibility of visual analysis. Few studies have investigated the influence of NCs on FHR variability and, to our knowledge, no one has evaluated its linear and nonlinear characteristics in antepartum and intrapartum period using a computerised analysis system. No differences in maternal characteristics, foetal pH at birth and 5-min Apgar score were observed. Birth weight was significantly lower in the 'multiple NCs' group, while 1-min Apgar score was lower in the BC group than the other groups, respectively. Foetuses with 'one or more NCs' evidenced a larger number of prolonged second stage and meconium-stained liquor cases, while the operative vaginal delivery and emergency caesarean section rates were unchanged. No relevant differences in cCTG parameters were observed, except for LTI, Delta and number of variable decelerations in antepartum period and only variable deceleration in intrapartum period.What are the implications of these findings for clinical practice and/or further research? cCTG monitoring results confirmed their usefulness for assessing the state of good oxygenation for all foetuses investigated.

The effect of nuchal cord on perinatal mortality and long-term offspring morbidity.

OBJECTIVE: To evaluate perinatal and long-term cardiovascular and respiratory morbidities of children born with nuchal cord. STUDY DESIGN: A large population-based cohort analysis of singleton deliveries was conducted. Maternal and birth characteristics, as well as cardiovascular and respiratory morbidity incidence were evaluated. Kaplan-Meier survival curves were used to compare cumulative hospitalization incidence between groups. Cox regression models were used to control for possible confounders and follow-up length. RESULTS: 243,682 deliveries were included. Of them, 34,332 (14.1%) were diagnosed with nuchal cord. Perinatal mortality rate was comparable between groups (0.5 vs. 0.6%, p = 0.16). Kaplan-Meier survival curves demonstrated no significant differences in cumulative cardiovascular or respiratory morbidity incidence between groups (log rank p = 0.69 and p = 0.10, respectively). Cox regression models reaffirmed a comparable risk for hospitalization between groups (aHR = 0.99 (95% CI 0.85-1.14, p = 0.87) and aHR = 0.97 (95% CI 0.92-1.02, p = 0.28). CONCLUSIONS: Nuchal cord is not associated with higher rate of perinatal mortality nor long-term cardiorespiratory morbidity.

Electronic Fetal Monitoring and Neonatal Outcomes when a Nuchal Cord Is Present at Delivery.

OBJECTIVE: This study aimed to determine the association between nuchal cord, electronic fetal monitoring parameters, and adverse neonatal outcomes. STUDY DESIGN: This was a prospective cohort study of 8,580 singleton pregnancies. Electronic fetal monitoring was interpreted, and patients with a nuchal cord at delivery were compared with those without. The primary outcome was a composite neonatal morbidity index. Logistic regression was used to adjust for confounders. RESULT: Of 8,580 patients, 2,071 (24.14%) had a nuchal cord. There was no difference in the risk of neonatal composite morbidity in patients with or without a nuchal cord (8.69 vs. 8.86%; p = 0.81). Nuchal cord was associated with category II fetal heart tracing and operative vaginal delivery (OVD) (6.4 vs. 4.3%; p < 0.01). CONCLUSION: Nuchal cord is associated with category II electronic fetal monitoring parameters, which may drive increased rates of OVD. However, there is no significant association with neonatal morbidity.

Comparative Spectrographic Analysis of the Newborns' Cry in the Presence of Tight Intrapartum Nuchal Cord vs. Normal using the Neonat App. Preliminary Results.

Background and objectives: The objective of this study was to contribute to the evaluation of the newborn (NB) cry as a means of communication and diagnosis. Materials and Methods: The study implied the recording of the spontaneous cry of 101 NBs with no intrapartum events (control sample), and of 72 NBs with nuchal cord (study sample) from the "Bega" University Clinic of Obstetrics-Gynecology and Neonatology of Timisoara, Romania. The sound analysis was based upon: Imagistic highlighting methods, descriptive statistics, and data mining techniques. Results: The differences between the cry of NBs with no intrapartum events and that of NBs affected by nuchal cord are statistically significant regarding the volume unit meter (VUM) (p = 0.0021) and the peak point meter (PPM) (p = 0.041). Conclusions: While clinically there are no differences between the two groups, the cry recorded from the study group (nuchal cord group) shows distinctive characteristics compared to the cry recorded from the control group (eventless intrapartum NBs group).

Evaluation of umbilical cord entanglement as a predictive factor of adverse pregnancy outcomes: A meta-analysis.

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.
