To examine the relationship between body mass index (BMI, kg/m) and incision-to-delivery interval total operative time at cesarean delivery.Women with singleton gestations undergoing uncomplicated primary repeat deliveries were identified from Maternal-Fetal Medicine Units Network Cesarean Registry. Women classified by BMI category of delivery (normal 18.5-24.9, overweight 25.0-29.9, obese 30.0-39.9, morbidly 40 or greater). Incision-to-delivery times during compared among three groups....
Abstract Objective To test our hypothesis that human fetal N‐terminal peptide of proB‐type natriuretic (NT‐proBNP) secretion is increased in proportion to the severity cardiovascular compromise intrauterine growth restriction. Methods This prospective cross‐sectional study consisted 42 growth‐restricted fetuses who underwent Doppler ultrasonographic examination hemodynamics within 7 days before delivery. Group 1 ( n = 13) had normal umbilical artery (UA) velocimetry. 2 15) abnormal UA and...
To assess the prevalence and risk of severe maternal morbidity among delivery hospitalization for stillbirth compared with live birth deliveries.Using data from Office Statewide Health Planning Development in California, we performed a population-based cross-sectional study 6,459,842 deliveries between 1999 2011. We identified using an algorithm comprising diagnoses procedures developed by Centers Disease Control Prevention used log-binomial regression models to examine relative (RR)...
We systematically characterized maternal serum proteome in women with clinical preeclampsia (PE) and asymptomatic early pregnancy that subsequently developed PE. Clinical PE cohort comprised 30 patients mild PE, severe 58 normotensive women. Preclinical included 149 whose samples were collected at 8-14 gestational weeks whom later 40 Serum was analyzed enzyme-linked immunosorbent assays used for protein quantification. In fibronectin, pappalysin-2, choriogonadotropin-beta, apolipoprotein...
Abstract Objective The objective of this article is to evaluate the utility fetal lung mass imaging for predicting neonatal respiratory distress. Method Pregnancies with masses between 2009 and 2014 at a single center were analyzed. Neonatal distress was defined as intubation mechanical ventilation birth, surgery before discharge, or extracorporeal membrane oxygenation (ECMO). predictive initial well maximal volume congenital pulmonary airway malformation ratio by ultrasound (US) magnetic...
Most studies of severe maternal morbidity (SMM) include only cases that occur during birth hospitalizations. We examined the increase in when including SMM antenatal and postpartum (within 42 days discharge) hospitalizations, using longitudinally linked data from 1,010,250 births California September 1, 2016, to December 31, 2018. For total SMM, expanding definition resulted 22.8% more cases; for nontransfusion 45.1% were added. Sepsis accounted 55.5% additional cases. The varied specific...
The high maternal mortality and severe morbidity rates in the United States compared with other high-income countries have received national attention. Characterization of postpartum hospital readmissions within first days after delivery hospitalization discharge could help to identify patients who need additional preparedness for discharge.
To assess whether readmission for hypertension by 6 weeks postpartum differed between patients discharged on nifedipine or labetalol.This cohort study included with delivery admissions from 2006 to 2017 who were the hospital labetalol and in a large, national adjudicated claims database. We identified patients' discharge medication based filled outpatient prescriptions. compared rates of alone, combined labetalol. Patients chronic without superimposed preeclampsia excluded. Comparisons...
Neonates with gastroschisis are often small for gestational age (SGA) based on population nomograms. Our objective was to evaluate the effect of SGA perinatal and neonatal outcomes in cases gastroschisis.This is a retrospective study neonates prenatally diagnosed from two academic centers between 2008 13. Perinatal at birth were compared appropriate-for-gestational-age (AGA) neonates. The primary composite outcome defined as any following: sepsis, short bowel syndrome discharge, prolonged...
The frequency of intrahepatic cholestasis pregnancy (ICP) peaks during the third trimester when plasma progesterone levels are highest. Furthermore, twin pregnancies characterized by higher than singletons and have a cholestasis. Therefore, we hypothesized that exogenous progestogens administered for reducing risk spontaneous preterm birth may increase Utilizing large IBM MarketScan Commercial Claims Encounters Database, investigated in patients treated with vaginal or intramuscular...
<b>Objective</b> Studies have reported an increased risk of spontaneous preterm birth associated with elevated prepregnancy body mass index (BMI) among nulliparous but not multiparous women. We examined whether changes in BMI and weight between pregnancies contributed to obese (BMI > 29 kg/m<sup>2</sup>) <b>Study Design</b> This study utilized maternally linked California records sequential singleton births 2007 2010. Preterm was defined as 20 31 or 32 36 weeks gestation. category change by...
Short leukocyte telomere length is a biomarker associated with stress and morbidity in non-pregnant adults. Little known, however, about maternal dynamics pregnancy. To address this, we examined changes (LTL) during uncomplicated pregnancies explored correlations perceived stress.In this pilot study, LTL was measured blood collected from nulliparas who delivered live, term, singleton infants between 2012 2018 at single institution. Participants were excluded if they had diabetes or...
Abstract Background . We hypothesised that human fetal cardiac natriuretic peptide secretion is increased in type‐1 diabetic pregnancies with normal placental hemodynamics, and this increase related to the first trimester maternal glycemic control. Methods Thirty‐two neonates of mothers 60 born after uncomplicated pregnancy labour (control group) were included study. Diabetic divided into two subgroups based on HbA1c value. Group 1 ( n =22) had a good control (HbA1c <7.5%) 2 =10) poor...
To investigate the effect of preterm gestational age (GA) on neonatal outcomes gastroschisis and to compare after spontaneous labor versus iatrogenic delivery both in early term periods.A retrospective study prenatally diagnosed cases born at Loma Linda University Medical Center Lucile Packard Children's Hospital (Loma Linda, CA) between January 2009 October 2016. A total 194 were identified included analysis. We compared infants delivered <37 0/7 those ≥37 weeks' gestation. Adverse outcome...
Objective The aim of this study is to assess whether the risk postpartum readmission within 6 weeks giving birth differs for women who had stillbirths compared with live births. Study Design Using data from Office Statewide Health Planning and Development in California, we performed a population-based cohort 7,398,640 births between 1999 2011. We identified diagnoses procedures associated first hospital that occurred after birth. used log-binomial models estimate relative (RR) stillbirth...
Objective: To investigate the association between meconium staining and perinatal neonatal outcomes in pregnancies with gastroschisis.Methods: Retrospective analysis of infants prenatally diagnosed gastroschisis born two academic medical centers 2008 2013. Neonatal deliveries without were compared. Primary outcome was defined as any following: sepsis, prolonged mechanical ventilation, bowel atresia or death. Secondary preterm delivery, preterm-premature rupture membranes (PPROM) hospital...
