Evidence is limited for the accuracy of Oligohydramnios to predict substantive perinatal morbidity and mortality in non–anomalous SGA fetuses monitored with normal Doppler studies. The aim of this study is to determine the association between amniotic fluid index and adverse perinatal outcomes in term SGA fetuses with normal Doppler studies. Method: This is a prospective observational study carried out by 340 pregnant women who were admitted to obstetrics unit, Sri Jayewardenepura from January 2019 to January 2023. Singleton pregnancies at term who were diagnosed with SGA (EFW 10<sup>th</sup> centile or AC 10<sup>th</sup> centile) with normal umbilical artery and middle cerebral artery Doppler studies were included. AFI was assessed predelivery and data were collected according to demographic details, mode of delivery, time of delivery, intrapartum events, and neonatal outcomes. Results: A total of 340 term pregnant women were studied. Out of them, 44% were in AFI more than 10 groups and 37% and 19% were in AFI 5 - 10 and less than 5 groups respectively. More obstetrics interventions were reported in AFI 5 groupa in terms of induction of labor (P 0.04) and emergency caesarean sections (P 0.003). No significant deference in immediate neonatal outcome was detected between each group. (Meconium-stained liquor (P 0.634), 1 minute APGAR (P 0.575) and 5-minute APGAR P 0.165)). Neonatal unit admission (P 0.001) and long-term neonatal complications were <span style="font-family:Verdana;.展开更多

Methods: We studied 289 late preterm births, classified as either aspontaneous late preterm birth (sLPTB) group (preterm labor with intact membranes and preterm premature rupture of membranes) or an indicated late preterm birth (iLPTB) group (hypertensive disorder in pregnancy, placental causes, and maternal diseases), according to the delivery indication. We then compared the maternal and neonatal characteristics and perinatal outcomes, including the Apgar score, admission to the neonatal intensive care unit (NICU) or special care nursery (SCN), duration of NICU stay, and the rate of composite morbidity (antibiotic use, hypoglycemia, hypocalcemia, hyperbilirubinemia requiring phototherapy, respiratory support, and respiratory distress syndrome). Results: A total of 198 neonates were in the sLPTB group and 91 were in the iLPTB group. In spite of greater gestational age at the time of delivery in the iLPTB group, the mean birth weight was lower than that in the sLPTB group. Additionally, the iLPTB group showed lower Apgar scores, and higher rates of NICU or SCN admission, respiratory support, and hypoglycemia, but there was no difference in the rate of composite morbidity between the two groups. Conclusion: iLPTB neonates had lower birth weights despite greater gestational age than those in the sLPTB group, but there was no difference in the rate of composite morbidity between the two groups.展开更多

They carry a high risk of maternal-fetal morbidity and mortality, thus constituting a public health problem. Several African countries have reported an upward trend in both the age of childbirth and the frequency of women with AMA over the past 20 years. In the Democratic Republic of Congo (DRC), where maternal and neonatal morbidity and mortality remain very high, data on AMA pregnancies go back more than 20 years. Objective: We propose evaluating obstetrical outcomes among women in AMA in our setting and the associated factors. Methods: This retrospective cohort study will be conducted in two healthcare facilities (ESS) in Kinshasa. The study population will consist of all women who delivered a single fetus after 28 weeks of gestation between January 2012 and December 2022 (10 years) in the selected ESS. The data collected will be analyzed using R software version 4.2.0. Quantitative variables will be summarized as means with standard deviation or medians with interquartile range. Qualitative variables will be presented as proportions (%). Multivariate logistic regression will be used to determine the main maternal-fetal complications associated with AMA and predictors of obstetric outcomes. P Discussion: The high maternal and infant mortality rates in DRC are among the highest in the world. The context of maternal age has become a topic of growing interest due to its potential implications for the health of women and newborns, it is crucial to identify the risk factors associated with obstetric outcomes by identifying obstetrical outcomes associated with advanced maternal age in the DRC. Many Congolese women tend to start their maternity journey at a relatively young age. However, there is also an emerging trend towards delayed childbearing, particularly in urban areas and among women with access to education and family planning services. Conclusion: The results of this study will enable us to update the frequency of AMA pregnancies in our environment. The socio-demographic and clinical profile of these pregnancies will be determined. The main maternal-fetal complications associated with AMA in our setting and the associated factors will be identified.展开更多

With the 12–23-mon IPI as the reference category, logistic regression analyzes were used to examine associations between different IPIs(<12, 12–23, 24–59, 60–119, and ≥120 mon) and perinatal outcomes(gestational diabetes mellitus, premature membrane rupture, gestational hypertension, preterm birth, low birth weight, and macrosomia).Compared with the 12–23-mon IPI category, women with longer IPIs had a higher risk of adverse perinatal outcomes, and those with an IPI ≥120 mon had the highest risk of gestational diabetes mellitus and premature membrane rupture(adjusted odds ratio(OR) 1.76, 95% confidence interval(CI) 1.32–2.35 and adjusted OR 2.03, 95% CI 1.53–2.67, respectively). These results indicate that a longer IPI is associated with a higher risk of adverse perinatal outcomes and an IPI of ≥120 mon appears to be independently associated with a higher risk of gestational diabetes mellitus and premature membrane rupture.展开更多

Objective: To compare AFI vs. SDVP at term as a predictor of adverse perinatal outcomes. Methods: A prospective observational study was conducted in Teaching Hospital Kandy, Sri Lanka for eight months from July 2015 to March 2016. 448 Singleton pregnancies admitted after 37 completed weeks were included. AFI ≤ 5 cm and SDVP < 2 cm were the exposure variables, which were related to outcome variables. Results: Mean AFI was 11.35 cm (SD = 5.15) and Mean SDVP was 4.07 cm (SD = 1.88). AFI and SDVP values showed a significant positive correlation (r = 0.954;p < 0.001). A significant percentage with low AFI needed induction of labour (RR 2.14, 95% CI 1.85 - 2.49). Low AFI was also a significant risk factor for not having an uneventful birth outcome (RR 2.682, 95% CI 1.082 - 6.642). Low SDVP was a significant risk factor for induction of labour (RR 1.83, 95% CI 1.434 - 2.334), operative delivery (RR 1.714, 95% CI 1.292 - 2.280), meconium-stained liquor (RR 2.67, 95% CI 1.342 - 5.308), and Apgar < 7 (RR 17.74, 95% CI 7.96 - 40.924). SDVP had better predictability than AFI for adverse perinatal outcomes. Conclusion: AFI better predicted oligohydramnios and subsequent labour induction than SDVP. Low SDVP was a risk factor for adverse perinatal outcomes (such as induction of labour, meconium-stained liquor, operative delivery, 5-minute Apgar less < 7, admission to special care baby units or perinatal deaths). In predicting adverse perinatal events, a higher potential was noted in SDVP method than AFI method. To determine the most predictive cut-off values of SDVP and AFI for each perinatal outcome, an in-depth experimental analysis is required in future research.展开更多

Methods: A retrospective population-based study of all deliveries during the years 2011-2020 in Philippe Maguilen SENGHOR Center was conducted. Perinatal outcome of patients with and without nuchal cord was compared. Results: Among 44,958 deliveries during the study period, 1.8% had a nuchal cord, documented at birth (n = 807). Higher rates of labor induction (9.1% vs. 3.2%;p 0.001) and non-reassuring fetal heart rate patterns (RR = 2.366;CI: 1.631 - 3.432) were noted among pregnancies with nuchal cord as compared with the control group. The cesarean delivery rate was significantly higher among pregnancies with a nuchal cord (39.5% vs. 21.8%;RR = 2333;CI: 2.023 - 2.692). Although 5 min Apgar scores lower than 7 were more common in pregnancies with a nuchal cord (7.8% vs. 3.8%;RR = 2.117;CI: 1.629 - 3.363). There was no statistical significance between the two groups for the perinatal mortality. Conclusion: Nuchal cord is associated with prolonged labor and adverse perinatal outcome.展开更多

Methods: This retrospective study consisted of 233 women undergoing instrumental vaginal deliveries from April 2020 to March 2021 at Paropakar Maternity and Women Hospital, a tertiary care hospital in Kathmandu, Nepal. Neonatal and maternal complications were analyzed. Results: Of 233 women, 102 (43.7%) and 131 (56.2%) had vacuum and forceps deliveries, respectively. The use of instruments was more frequent in infants with higher birth weight and gestational age. There were no significant differences in Apgar scores between the two groups. Two main indications of instrumental deliveries were fetal distress and prolonged second stage labor. Forceps, compared with vacuum, more often caused 3<sup>rd</sup>/4<sup>th</sup> perineal tears, tear extending to fornices, and postpartum hemorrhage. Neonatal outcomes were similar in both types of instrumental deliveries. Conclusion: Instrumental vaginal delivery caused maternal morbidity and procedure/judgment training for it is essential.展开更多

Maternal outcomes for patients diagnosed with ICP are usually good. However, fetal outcomes can be devastating with high frequencies of perinatal complications. Patients with ICP generally have an early delivery due to fetal complications. The current hypothesis is that ICP has higher frequencies of fetal complications due to high concentrations of BA which has toxic cellular effects to many organs. In lungs, it destroys the AT-II cells, decreasing phospholipids synthesis leading to the alveolar capillary permeability to increase and pulmonary surfactant to decrease. In heart, cholate can cross into the fetal compartment and causing fetal arrhythmias and decreased contractility. In the nervous system, high BAs can cause nerve cell denaturation and necrosis, mitochondria edema and membrane dissolve. In the placenta, high BA concentration can cause edema of the villous, decrease number of villous, intervillous thickening and balloon formation.In addition, high total BA can result in chorionic vein constriction and impaired fetal adrenal function.展开更多

The aim of this study was to determine the risk factors associated with prenatal outcome in acute appendicitis during second and third trimester pregnancies. Methods This was a retrospective single-center study that presented a descriptive analysis of the results. A total of 102 pregnant women who were diagnosed with acute appendicitis and operated upon in Peking University Third Hospital, China between January 1993 and December 2007 were presented. SPSS 12.0 for Windows was used for data analysis. Results Seventy-eight pregnant women who were diagnosed with acute appendicitis （sixteen patients had a perforated appendix, 62 patients had a non-perforated appendix） were operated upon during late pregnancy. The interval between symptom onset and surgery was the only predictive variable. A longer interval between symptom onset and surgery was associated with appendix perforation （（109.5±52.7） hours） than with no appendix perforation （（35.1±19.62） hours; P=-0.007）. There was a significant difference in the rate of preterm labor （5.1% vs 1.3%） and the rate of fetal mortality （25% vs 1.7%） between patients with and without a perforated appendix. Conclusions Delaying surgery correlates to more advanced disease with an increased risk of perforation. This contributes to an increased risk of further complications, including premature labor or abortion, and to higher maternal complication rates. Prompt diagnosis may improve the prenatal outcome.展开更多

文摘Background and Aim: Delivery of a fetus with SGA is associated with increased risk of perinatal morbidity and mortality. Evidence is limited for the accuracy of Oligohydramnios to predict substantive perinatal morbidity and mortality in non–anomalous SGA fetuses monitored with normal Doppler studies. The aim of this study is to determine the association between amniotic fluid index and adverse perinatal outcomes in term SGA fetuses with normal Doppler studies. Method: This is a prospective observational study carried out by 340 pregnant women who were admitted to obstetrics unit, Sri Jayewardenepura from January 2019 to January 2023. Singleton pregnancies at term who were diagnosed with SGA (EFW 10<sup>th</sup> centile or AC 10<sup>th</sup> centile) with normal umbilical artery and middle cerebral artery Doppler studies were included. AFI was assessed predelivery and data were collected according to demographic details, mode of delivery, time of delivery, intrapartum events, and neonatal outcomes. Results: A total of 340 term pregnant women were studied. Out of them, 44% were in AFI more than 10 groups and 37% and 19% were in AFI 5 - 10 and less than 5 groups respectively. More obstetrics interventions were reported in AFI 5 groupa in terms of induction of labor (P 0.04) and emergency caesarean sections (P 0.003). No significant deference in immediate neonatal outcome was detected between each group. (Meconium-stained liquor (P 0.634), 1 minute APGAR (P 0.575) and 5-minute APGAR P 0.165)). Neonatal unit admission (P 0.001) and long-term neonatal complications were <span style="font-family:Verdana;.
文摘Objective: We aimed to compare the perinatal outcomes in late preterm spontaneous and indicated birth neonates. Methods: We studied 289 late preterm births, classified as either aspontaneous late preterm birth (sLPTB) group (preterm labor with intact membranes and preterm premature rupture of membranes) or an indicated late preterm birth (iLPTB) group (hypertensive disorder in pregnancy, placental causes, and maternal diseases), according to the delivery indication. We then compared the maternal and neonatal characteristics and perinatal outcomes, including the Apgar score, admission to the neonatal intensive care unit (NICU) or special care nursery (SCN), duration of NICU stay, and the rate of composite morbidity (antibiotic use, hypoglycemia, hypocalcemia, hyperbilirubinemia requiring phototherapy, respiratory support, and respiratory distress syndrome). Results: A total of 198 neonates were in the sLPTB group and 91 were in the iLPTB group. In spite of greater gestational age at the time of delivery in the iLPTB group, the mean birth weight was lower than that in the sLPTB group. Additionally, the iLPTB group showed lower Apgar scores, and higher rates of NICU or SCN admission, respiratory support, and hypoglycemia, but there was no difference in the rate of composite morbidity between the two groups. Conclusion: iLPTB neonates had lower birth weights despite greater gestational age than those in the sLPTB group, but there was no difference in the rate of composite morbidity between the two groups.
文摘Objective:Regarding frozen-thawed embryo transfer(FET),there is limited consensus on whether extending embryo culture from the cleavage stage to the blastocyst stage affects perinatal outcomes.This study aimed to compare perinatal outcomes of singletons between blastocyst-stage embryo transfer(BT)and cleavage-stage embryo transfer(CT)in FET.Methods:A total of 9408 FET cycles that met the inclusion criteria were included in this retrospective cohort study between 2019 and 2022.Blastocyst-stage embryo transfers were performed in the BT group,and cleavage-stage embryo transfers were performed in the CT group.Multivariate logistic regression analyses were performed,as well as propensity score matching(PSM)to adjust for confounders.Results:After PSM,a higher risk of pre-term birth(PTB;odds ratio[OR]:1.23,95%confidence interval[CI]:1.00-1.50,P=0.048)and being large for gestational age(LGA;OR:1.16,95%CI:1.00-1.35,P=0.050)was observed in the BT group compared to that in the CT group.After stratified PSM,in the subgroup under 35 years of age,only an increased risk of LGA was observed in the BT group compared to the CT group.Perinatal outcomes in the double-embryo transfer subgroup were similar to those in the unstratified group.However,in the subgroup beyond 35 years of age and the single embryo transfer subgroup,perinatal outcomes were not statistically different between the BT and CT groups(P>0.05).Conclusions:In FET,prolonged embryo culture to the blastocyst stage increased the risk of PTB and LGA in single fetuses.However,stratified analysis based on age and the number of transferred embryos yielded different results,necessitating further mechanistic studies.
文摘Drug abuse by pregnant women is one of the significant problems for mothers and their neonates.This study aimed to investigate the effects of maternal substance use disorder during pregnancy on neonatal developmental criteria.In a case-control study,clinical records of 90 neonates diagnosed with neonatal abstinence syndrome who were admitted to NICU in one of four hospitals affiliated with Shahid-Beheshti University of Medical Sciences in Tehran,Iran between 2017 and 2020 were compared to 90 neonates without neonatal abstinence syndrome(control group).Demographic information and data for neonatal developmental characteristics and complications were extracted from the clinical records of this convenience sample.Data for the type and method of maternal substance use during pregnancy were collected through a telephone call with mothers.Our data showed that the prevalence of drug addiction was 1.8%among pregnant women,and the most common drugs used by mothers were opium(n=45%,50%),amphetamine(n=30%,33%),and methadone(n=14%,16%).Neonates with abstinence syndrome had a higher prevalence of transient tachypnea of the newborn(TTN)(P=0.004),and a prevalence of being admitted to NICU(P=0.05)and for a longer duration(P<0.001).Their mothers had a higher prevalence of having pre-eclampsia(P=0.010).Using morphine vs.amphetamine showed no difference based on their effects on mothers and neonates.Substance use during pregnancy increased the prevalence of pregnancy complications(pre-eclampsia)and neonatal complications(TTN and prevalence and duration of hospitalization).Therefore,planning for the development of health policies to raise awareness among women and more broadly,all members of the community,is important to prevent the tendency to engage in this potentially high-risk behavior.
文摘Assisted reproductive technology(ART)has evolved rapidly over the last 40 years,offering hope to individuals and couples struggling with infertility.As technology continues to evolve,simulating a realistic female reproductive system environment has become a common goal for all types of ARTs,thereby reducing the impact of the artificial microenvironment on perinatal and offspring health.In this review,we provide a brief history of the development of each major ART and discuss the impact of ART on perinatal and offspring health.We also explore how the negative consequences of ART may be overcome and how its benefits can be maximized.
文摘Introduction: Pregnancies at advanced maternal age (AMA) are those occurring after the age of 35 years old. They carry a high risk of maternal-fetal morbidity and mortality, thus constituting a public health problem. Several African countries have reported an upward trend in both the age of childbirth and the frequency of women with AMA over the past 20 years. In the Democratic Republic of Congo (DRC), where maternal and neonatal morbidity and mortality remain very high, data on AMA pregnancies go back more than 20 years. Objective: We propose evaluating obstetrical outcomes among women in AMA in our setting and the associated factors. Methods: This retrospective cohort study will be conducted in two healthcare facilities (ESS) in Kinshasa. The study population will consist of all women who delivered a single fetus after 28 weeks of gestation between January 2012 and December 2022 (10 years) in the selected ESS. The data collected will be analyzed using R software version 4.2.0. Quantitative variables will be summarized as means with standard deviation or medians with interquartile range. Qualitative variables will be presented as proportions (%). Multivariate logistic regression will be used to determine the main maternal-fetal complications associated with AMA and predictors of obstetric outcomes. P Discussion: The high maternal and infant mortality rates in DRC are among the highest in the world. The context of maternal age has become a topic of growing interest due to its potential implications for the health of women and newborns, it is crucial to identify the risk factors associated with obstetric outcomes by identifying obstetrical outcomes associated with advanced maternal age in the DRC. Many Congolese women tend to start their maternity journey at a relatively young age. However, there is also an emerging trend towards delayed childbearing, particularly in urban areas and among women with access to education and family planning services. Conclusion: The results of this study will enable us to update the frequency of AMA pregnancies in our environment. The socio-demographic and clinical profile of these pregnancies will be determined. The main maternal-fetal complications associated with AMA in our setting and the associated factors will be identified.

文摘We conducted a retrospective cohort study of 9,552 women experiencing their second delivery between 2014 and 2016 at the International Peace Maternity and Child Health Hospital to investigate the association between the interpregnancy interval(IPI)and adverse perinatal outcomes. With the 12–23-mon IPI as the reference category, logistic regression analyzes were used to examine associations between different IPIs(<12, 12–23, 24–59, 60–119, and ≥120 mon) and perinatal outcomes(gestational diabetes mellitus, premature membrane rupture, gestational hypertension, preterm birth, low birth weight, and macrosomia).Compared with the 12–23-mon IPI category, women with longer IPIs had a higher risk of adverse perinatal outcomes, and those with an IPI ≥120 mon had the highest risk of gestational diabetes mellitus and premature membrane rupture(adjusted odds ratio(OR) 1.76, 95% confidence interval(CI) 1.32–2.35 and adjusted OR 2.03, 95% CI 1.53–2.67, respectively). These results indicate that a longer IPI is associated with a higher risk of adverse perinatal outcomes and an IPI of ≥120 mon appears to be independently associated with a higher risk of gestational diabetes mellitus and premature membrane rupture.
文摘Introduction: Oligohydramnios is an important sign of fetal jeopardy and amniotic fluid index (AFI) and single deepest vertical pocket (SDVP) have been used to detect it. Objective: To compare AFI vs. SDVP at term as a predictor of adverse perinatal outcomes. Methods: A prospective observational study was conducted in Teaching Hospital Kandy, Sri Lanka for eight months from July 2015 to March 2016. 448 Singleton pregnancies admitted after 37 completed weeks were included. AFI ≤ 5 cm and SDVP < 2 cm were the exposure variables, which were related to outcome variables. Results: Mean AFI was 11.35 cm (SD = 5.15) and Mean SDVP was 4.07 cm (SD = 1.88). AFI and SDVP values showed a significant positive correlation (r = 0.954;p < 0.001). A significant percentage with low AFI needed induction of labour (RR 2.14, 95% CI 1.85 - 2.49). Low AFI was also a significant risk factor for not having an uneventful birth outcome (RR 2.682, 95% CI 1.082 - 6.642). Low SDVP was a significant risk factor for induction of labour (RR 1.83, 95% CI 1.434 - 2.334), operative delivery (RR 1.714, 95% CI 1.292 - 2.280), meconium-stained liquor (RR 2.67, 95% CI 1.342 - 5.308), and Apgar < 7 (RR 17.74, 95% CI 7.96 - 40.924). SDVP had better predictability than AFI for adverse perinatal outcomes. Conclusion: AFI better predicted oligohydramnios and subsequent labour induction than SDVP. Low SDVP was a risk factor for adverse perinatal outcomes (such as induction of labour, meconium-stained liquor, operative delivery, 5-minute Apgar less < 7, admission to special care baby units or perinatal deaths). In predicting adverse perinatal events, a higher potential was noted in SDVP method than AFI method. To determine the most predictive cut-off values of SDVP and AFI for each perinatal outcome, an in-depth experimental analysis is required in future research.

文摘Background:Intrahepatic cholestasis of pregnancy(ICP)increases the risk of adverse pregnancy outcomes.This study aimed to explore the association between serum syndecan-1 and glypican-3 levels and the adverse perinatal outcome as well as the responses to the treatment of ursodeoxycholic acid(UDCA).Methods:This prospective,case control study included 88 pregnant women(44 women with ICP and 44 healthy controls).The primary end points were the perinatal outcome and the response to UDCA therapy.A logistic regression model was used to identify the independent risk factors of adverse pregnancy outcomes and reduced response to UDCA therapy.Results:Women with ICP had significantly higher serum syndecan-1(1.27±0.36 ng/m L vs.0.98±0.50 ng/m L;P=0.003),glypican-3(1.78±0.13 ng/m L vs.1.69±0.16 ng/m L;P=0.004),AST(128.59±1.44 vs.13.29±1.32 U/L;P<0.001),and ALT(129.84±1.53 vs.8.00±3.67 U/L;P<0.001)levels compared with the controls.The increased levels of syndecan-1(OR=4.715,95%CI:1.554–14.310;P=0.006),glypican-3(OR=8.465,95%CI:3.372–21.248;P=0.007),ALT(OR=1.382,95%CI:1.131–1.690;P=0.002),and postprandial bile acid(PBA)(OR=3.392,95%CI:1.003–12.869;P=0.026)were correlated to ICP.The adverse neonatal outcome was related to increased glypican-3(OR=4.275,95%CI:2.726–5.635;P=0.039),and PBA(OR=3.026,95%CI:1.069–13.569;P=0.037).Increases of syndecan-1(OR=7.464,95%CI:2.130–26.153,P=0.017)and glypican-3(OR=6.194,95%CI:2.951–13.002;P=0.025)were the risk factors of decreased response to UDCA treatment.Conclusion:Syndecan-1 and glypican-3 might be powerful determinants in predicting adverse perinatal outcome in patients with ICP,and they can be used to predict the response to the UDCA treatment.
文摘Objective: The present study was aimed at evaluating the outcome of pregnancies with a nuchal cord. Methods: A retrospective population-based study of all deliveries during the years 2011-2020 in Philippe Maguilen SENGHOR Center was conducted. Perinatal outcome of patients with and without nuchal cord was compared. Results: Among 44,958 deliveries during the study period, 1.8% had a nuchal cord, documented at birth (n = 807). Higher rates of labor induction (9.1% vs. 3.2%;p 0.001) and non-reassuring fetal heart rate patterns (RR = 2.366;CI: 1.631 - 3.432) were noted among pregnancies with nuchal cord as compared with the control group. The cesarean delivery rate was significantly higher among pregnancies with a nuchal cord (39.5% vs. 21.8%;RR = 2333;CI: 2.023 - 2.692). Although 5 min Apgar scores lower than 7 were more common in pregnancies with a nuchal cord (7.8% vs. 3.8%;RR = 2.117;CI: 1.629 - 3.363). There was no statistical significance between the two groups for the perinatal mortality. Conclusion: Nuchal cord is associated with prolonged labor and adverse perinatal outcome.

文摘BACKGROUND Preeclampsia(PE)is a pregnancy syndrome of undetermined etiology;inflammation was one of the proposed theories for its development.AIM To examine the platelet to lymphocyte ratio(PLR),an inflammatory biomarker,as a marker to predict poor maternal-neonatal outcomes in early-onset PE(EoPE).METHODS A cross-sectional study enrolled 60 pregnant women with EoPE(at 32-30 wk of gestation)at a university hospital.Demographic criteria and hematological indices were collected,including platelet counts and indices(mean platelet volume and platelet distribution width),PLR,and the Doppler study,which calculated estimated fetal weight(EFW),amniotic fluid index(AFI),resistance index(RI),and pulsatility index(PI).Participants were followed until delivery,where maternal outcomes were recorded,including;delivery mode and reason for cesarean section,and neonatal outcomes,including fetal growth restriction(FGR),meconium-stained liquid,the 5-min Apgar score,and admission to the intensive care unit.RESULTS There was a trend of insignificant increases in cesarean sections.Sixty-one-point two percent(37/60)fetuses were admitted to the neonatal care unit;70.0%of admitted fetuses were meconium-stained liquor,and 56.7%of them had FGR.PLR was positively correlated with AFI and EFW as r=0.98,0.97,P<0.001;PLR showed negative correlations with PI and RI as r=-0.99,-0.98,P<0.001.The Apgar score and the number of days admitted to the intensive care unit had a positive and negative correlation(0.69,-0.98),P<0.0001,respectively.Receiver operating characteristic calculated a PLR cutoff value(7.49)that distinguished FGR at 100%sensitivity and 80%specificity.CONCLUSION Strong,meaningful relationships between PLR and FGR parameters and a poor neonatal outcome with a significant P value make it a recommendable biomarker for screening EoPE-related complications.Further studies are suggested to see the impact on maternal-neonatal health.

文摘Pregnancy is rare and difficult in Sheehan syndrome patients.With the help of assisted reproductive technology,the patients even with panhypopituitarism can get pregnant again.Moreover,women with hypopituitarism have increased risk of pregnancy complications.Here we report a patient who suffered acute and severe Sheehan syndrome with panhypopituitarism and central diabetes insipidus got pregnant again by in vitro fertilization and embryo transfer.A regular and careful antenatal care was given by the cooperation between obstetricians and endocrinologists.Finally,she delivered a healthy female baby at 37+6 weeks of gestation with Apgar scores of 10 and 10 at 1 and 5 minutes,respectively.The patient and her baby were doing well at postpartum follow-up.The related articles were also reviewed.This case report is aimed to help clinical practitioners to make better decisions on the management of Sheehan syndrome or other type of hypopituitarism during pregnancy.
文摘Aim: To determine maternal and neonatal morbidities associated with instrumental vaginal delivery. Methods: This retrospective study consisted of 233 women undergoing instrumental vaginal deliveries from April 2020 to March 2021 at Paropakar Maternity and Women Hospital, a tertiary care hospital in Kathmandu, Nepal. Neonatal and maternal complications were analyzed. Results: Of 233 women, 102 (43.7%) and 131 (56.2%) had vacuum and forceps deliveries, respectively. The use of instruments was more frequent in infants with higher birth weight and gestational age. There were no significant differences in Apgar scores between the two groups. Two main indications of instrumental deliveries were fetal distress and prolonged second stage labor. Forceps, compared with vacuum, more often caused 3<sup>rd</sup>/4<sup>th</sup> perineal tears, tear extending to fornices, and postpartum hemorrhage. Neonatal outcomes were similar in both types of instrumental deliveries. Conclusion: Instrumental vaginal delivery caused maternal morbidity and procedure/judgment training for it is essential.

文摘Intrahepatic cholestasis of pregnancy(ICP) is a peculiar disease in middle-late pregnancy with the pathological characteristics of hepatic capillary bile duct silts and is accompanied by clinical presentations of pruritus and bile acid(BA) elevation in serum. Maternal outcomes for patients diagnosed with ICP are usually good. However, fetal outcomes can be devastating with high frequencies of perinatal complications. Patients with ICP generally have an early delivery due to fetal complications. The current hypothesis is that ICP has higher frequencies of fetal complications due to high concentrations of BA which has toxic cellular effects to many organs. In lungs, it destroys the AT-II cells, decreasing phospholipids synthesis leading to the alveolar capillary permeability to increase and pulmonary surfactant to decrease. In heart, cholate can cross into the fetal compartment and causing fetal arrhythmias and decreased contractility. In the nervous system, high BAs can cause nerve cell denaturation and necrosis, mitochondria edema and membrane dissolve. In the placenta, high BA concentration can cause edema of the villous, decrease number of villous, intervillous thickening and balloon formation.In addition, high total BA can result in chorionic vein constriction and impaired fetal adrenal function.
文摘Objective:To assess the obstetric and neonatal outcomes associated with adolescent pregnancy in Iran.Methods:We retrospectively assessed women who gave birth between January 1st,2020,and January 1st,2022.These pregnant women were separated into two groups:(1)women aged 19 and younger;(2)women aged 20-34 years.Main outcome measures include preterm birth,maternal comorbidities,preeclampsia,eclampsia,low birth weight(LBW),intrauterine growth restriction(IUGR),placenta abnormalities,placenta abruption,cho-rioamnionitis,meconium fluid,fetal distress,methods of delivery,rate of cesarean section(CS),perineal lacer-ations,postpartum hemorrhage,childbirth trauma,shoulder dystocia,congenital malformation,and unfavorable maternal and neonatal outcome.Logistic regression models were used to determine the influence of teenage pregnancy on adverse pregnancy and childbirth outcomes.Results:Of 7033 deliveries,92.4%of women were adults,and 7.6%were adolescents.Adolescents residing in rural districts were more common than adults(42.3%vs.33.7%).However,access to prenatal facility care was the same as the majority of women had 6-10 prenatal care visits during their pregnancy.There was no difference in the risk of preeclampsia,placenta abruption,placenta previa,fetal distress,preterm labor,shoulder dystocia,perineal lacerations,childbirth trauma,congenital malformation,postpartum hemorrhage,intensive care unit admission,maternal death,and unfavorable neonatal outcome including stillbirth,neonatal intensive care unit admission,neonatal death in adolescent pregnancies compared to adults.Adolescents had a significantly higher risk of LBW(OR:1.47,95%CI:1.01-2.73),IUGR(OR:1.96,95%CI:1.31-2.45),and meconium fluid(OR:1.74,95%CI:1.41-2.32),however,there was no statistically significant difference after adjusting the confounding factors.Compared with adults,adolescents had a significantly lower risk of CS(aRR:0.67,95%CI:0.51-0.77)and a lower risk of gestational diabetes(aRR:0.78,95%CI:0.51-0.95).Conclusions:Although we found no serious consequences of adolescent pregnancy,more research is needed to reach a more accurate conclusion about teenage pregnancy.
文摘Background:Preterm premature rupture of membranes(PPROM)is associated with high neonatal morbidity and mortality.However,the influences of cesarean section(CS)on neonatal outcomes in preterm pregnancies complicated with PPROM are not well elucidated.The aim of this study was to investigate the influence of delivery modes on neonatal outcomes among pregnant women with PPROM.Methods:A retrospective cross-sectional study was conducted in 39 public hospitals in 14 cities in the mainland of China from January 1st,2011 to December 31st,2011.A total of 2756 singleton pregnancies complicated with PPROM were included.Adverse neonatal outcomes including early neonatal death,birth asphyxia,respiratory distress syndrome(RDS),pneumonia,infection,birth trauma,and 5-min/10-min Apgar scores were obtained from the hospital records.Binary variables and ordinal variables were respectively calculated by binary logistic regressions and ordinal regression.Numerical variables were compared by multiple linear regressions.Results:In total,2756 newborns were involved in the analysis.Among them,1166 newborns(42.31%)were delivered by CS and 1590 newborns belonged to vaginal delivery(VD)group.The CS proportion of PPROM obviously increased with the increase of gestational age(x2=5.014,P=0.025).Compared with CS group,VD was associated with a higher risk of total newborns mortality(odds ratio[OR],2.38;95%confidence interval[Cl],1.102-5.118;P=0.027),and a lower level of pneumonia(OR,0.32;95%Cl,0.126-0.811;P=0.016).However,after multivariable adjustment and stratification for gestational age,only pneumonia was significantly related with CS in 28 to 34 weeks group(OR,0.34;95%Cl,0.120-0.940;P=0.038).There were no differences regarding to other adverse outcomes in the two groups,including neonatal mortality,birth asphyxia,Apgar scores,RDS,pneumonia,and sepsis.Conclusions:The proportion of CS of pregnant women with PPROM was very high in China.The mode of delivery does not affect neonatal outcomes of pregnancies complicated with PPROM.
文摘Objective:To compare the adverse maternal and neonatal outcomes of multiple pregnancy and singleton pregnancy from multiple medical centers in Beijing.Methods:Data concerning maternal and neonatal adverse outcomes in multiple and singleton pregnancies were collected from 15 hospitals in Beijing by a systemic cluster sampling survey conducted from 20 June to 30 November 2013.The SPSS software (version 20.0) was used for data analysis.The x2 test was used tbr statistical analyses.Results:The rate of caesarean deliveries was much higher in women with multiple pregnancies (85.8％) than that in women with singleton pregnancies (42.6％,X2 =190.8,P ＜ 0.001).The incidences of anemia (X2 =40.023,P ＜ 0.001),preterm labor (X2 =1021.172,P ＜ 0.001),gestational diabetes mellitus (X2 =9.311,P ＜ 0.01),hypertensive disorders (X2 =122.708,P ＜ 0.001)and post-partum hemorrhage (X2-48.550,P ＜ 0.001) was significantly increased with multiple pregnancy.In addition,multiple pregnancy was associated with a significantly higher rate of small-for-gestational-age infants (X2 =92.602,P ＜ 0.001),low birth weight (X2 =1141.713,P ＜ 0.001),and neonatal intensive care unit (NICU) admission (X2 =340.129,P＜ 0.001).Conclusions:Multiple pregnancy is a significant risk factor for adverse maternal and neonatal outcomes in Beijing.Improving obstetric care for multiple pregnancy,particularly in reducing preterm labor,is required to reduce the risk to mothers and infants.
文摘Background Appendicitis is the most common surgical problem in pregnancy, however the particular dangers of appendicitis in pregnancy lie in the varied presentation of symptoms and the higher chance of delayed diagnosis. The aim of this study was to determine the risk factors associated with prenatal outcome in acute appendicitis during second and third trimester pregnancies. Methods This was a retrospective single-center study that presented a descriptive analysis of the results. A total of 102 pregnant women who were diagnosed with acute appendicitis and operated upon in Peking University Third Hospital, China between January 1993 and December 2007 were presented. SPSS 12.0 for Windows was used for data analysis. Results Seventy-eight pregnant women who were diagnosed with acute appendicitis （sixteen patients had a perforated appendix, 62 patients had a non-perforated appendix） were operated upon during late pregnancy. The interval between symptom onset and surgery was the only predictive variable. A longer interval between symptom onset and surgery was associated with appendix perforation （（109.5±52.7） hours） than with no appendix perforation （（35.1±19.62） hours; P=-0.007）. There was a significant difference in the rate of preterm labor （5.1% vs 1.3%） and the rate of fetal mortality （25% vs 1.7%） between patients with and without a perforated appendix. Conclusions Delaying surgery correlates to more advanced disease with an increased risk of perforation. This contributes to an increased risk of further complications, including premature labor or abortion, and to higher maternal complication rates. Prompt diagnosis may improve the prenatal outcome.
