RESUMEN

INTRODUCTION AND HYPOTHESIS: The objective was to evaluate the safety and effectiveness of an intrapartum electromechanical pelvic floor dilator designed to reduce the risk of levator ani muscle (LAM) avulsion during vaginal delivery. METHODS: A multicenter, randomized controlled trial enrolled nulliparous participants planning vaginal delivery. During the first stage of labor, participants were randomized to receive the intravaginal device or standard-of-care labor management. The primary effectiveness endpoint was the presence of full LAM avulsion on transperineal pelvic-floor ultrasound at 3 months. Three urogynecologists performed blinded interpretation of ultrasound images. The primary safety endpoint was adverse events (AEs) through 3 months. RESULTS: A total of 214 women were randomized to Device (n = 113) or Control (n = 101) arms. Of 113 Device assignees, 82 had a device placed, of whom 68 delivered vaginally. Of 101 Control participants, 85 delivered vaginally. At 3 months, 110 participants, 46 Device subjects who received full device treatment, and 64 Controls underwent ultrasound for the per-protocol analysis. No full LAM avulsions (0.0%) occurred in the Device group versus 7 out of 64 (10.9%) in the Control group (p = 0.040; two-tailed Fisher's test). A single maternal serious AE (laceration) was device related; no neonate serious AEs were device related. CONCLUSIONS: The pelvic floor dilator device significantly reduced the incidence of complete LAM avulsion in nulliparous individuals undergoing first vaginal childbirth. The dilator demonstrated an acceptable safety profile and was well received by recipients. Use of the intrapartum electromechanical pelvic floor dilator in laboring nulliparous individuals may reduce the rate of LAM avulsion, an injury associated with serious sequelae including pelvic organ prolapse.

RESUMEN

As treatments for diseases throughout the body progress, treatment for many brain diseases has been at a standstill due to difficulties in drug delivery. While new drugs are being discovered in vitro, these therapies are often hindered by inefficient tissue distribution and, more commonly, an inability to cross the blood brain barrier. Mesenchymal stem cells are thus being investigated as a delivery tool to directly target therapies to the brain to treat wide array of brain diseases. This review discusses the use of mesenchymal stem cells in hypoxic disease (hypoxic ischemic encephalopathy), an inflammatory neurodegenerative disease (multiple sclerosis), and a malignant condition (glioma).

RESUMEN

OBJECTIVE: The aim of the article is to evaluate and compare labor outcomes in obese patients undergoing induction of labor (IOL) with misoprostol and dinoprostone. STUDY DESIGN: This was a retrospective review of patients who delivered from February 1, 2008, to July 1, 2013 at our institution. All obese women who underwent IOL were identified. The rates of successful cervical ripening and cesarean delivery (CD) for patients who underwent IOL with misoprostol and dinoprostone were calculated and compared. RESULTS: A total of 564 women met inclusion criteria; 297 (52.7%) were induced with misoprostol, and 267 (47.3%) were induced with dinoprostone. The misoprostol group had a higher successful cervical ripening rate (78.1 vs. 66.7%; odds ratio [OR], 1.79; 95% confidence interval [CI], 1.23-2.6; p = 0.002) and a lower CD rate (39.1 vs. 51.3%; OR, 0.61; 95% CI, 0.44-0.85; p = 0.003) than the dinoprostone group. This significance persisted in a multivariate model adjusting for parity, gestational age, birth weight, and indication for IOL. The rates of tachysystole, terbutaline use, postpartum hemorrhage, and infectious morbidity were comparable in both groups, as were Apgar scores, rates of neonatal intensive care unit admission, and meconium passage. CONCLUSION: In obese women undergoing IOL, misoprostol leads to a higher successful cervical ripening rate and a lower CD rate than dinoprostone, with a similar rate of peripartum complications and neonatal outcomes.

RESUMEN

OBJECTIVE: To estimate the association between mean arterial pressure during pregnancy and neonatal outcomes in participants with chronic hypertension using data from the CHAP (Chronic Hypertension and Pregnancy) trial. METHODS: A secondary analysis of the CHAP trial, an open-label, multicenter randomized trial of antihypertensive treatment in pregnancy, was conducted. The CHAP trial enrolled participants with mild chronic hypertension (blood pressure [BP] 140-159/90-104 mm Hg) and singleton pregnancies less than 23 weeks of gestation, randomizing them to active treatment (maintained on antihypertensive therapy with a goal BP below 140/90 mm Hg) or standard treatment (control; antihypertensives withheld unless BP reached 160 mm Hg systolic BP or higher or 105 mm Hg diastolic BP or higher). We used logistic regression to measure the strength of association between mean arterial pressure (average and highest across study visits) and to select neonatal outcomes. Unadjusted and adjusted odds ratios (per 1-unit increase in millimeters of mercury) of the primary neonatal composite outcome (bronchopulmonary dysplasia, retinopathy of prematurity, necrotizing enterocolitis, or intraventricular hemorrhage grade 3 or 4) and individual secondary outcomes (neonatal intensive care unit admission [NICU], low birth weight [LBW] below 2,500 g, and small for gestational age [SGA]) were calculated. RESULTS: A total of 2,284 participants were included: 1,155 active and 1,129 control. Adjusted models controlling for randomization group demonstrated that increasing average mean arterial pressure per millimeter of mercury was associated with an increase in each neonatal outcome examined except NEC, specifically neonatal composite (adjusted odds ratio [aOR] 1.12, 95% CI, 1.09-1.16), NICU admission (aOR 1.07, 95% CI, 1.06-1.08), LBW (aOR 1.12, 95% CI, 1.11-1.14), SGA below the fifth percentile (aOR 1.03, 95% CI, 1.01-1.06), and SGA below the 10th percentile (aOR 1.02, 95% CI, 1.01-1.04). Models using the highest mean arterial pressure as opposed to average mean arterial pressure also demonstrated consistent associations. CONCLUSION: Increasing mean arterial pressure was positively associated with most adverse neonatal outcomes except NEC. Given that the relationship between mean arterial pressure and adverse pregnancy outcomes may not be consistent at all mean arterial pressure levels, future work should attempt to further elucidate whether there is an absolute threshold or relative change in mean arterial pressure at which fetal benefits are optimized along with maternal benefits.

RESUMEN

OBJECTIVE: To evaluate maternal and neonatal outcomes by type of antihypertensive used in participants of the CHAP (Chronic Hypertension in Pregnancy) trial. METHODS: We conducted a planned secondary analysis of CHAP, an open-label, multicenter, randomized trial of antihypertensive treatment compared with standard care (no treatment unless severe hypertension developed) in pregnant patients with mild chronic hypertension (blood pressure 140-159/90-104 mm Hg before 20 weeks of gestation) and singleton pregnancies. We performed three comparisons based on medications prescribed at enrollment: labetalol compared with standard care, nifedipine compared with standard care, and labetalol compared with nifedipine. Although active compared with standard care groups were randomized, medication assignment within the active treatment group was not random but based on clinician or patient preference. The primary outcome was the occurrence of superimposed preeclampsia with severe features, preterm birth before 35 weeks of gestation, placental abruption, or fetal or neonatal death. The key secondary outcome was small for gestational age (SGA) neonates. We also compared medication adverse effects between groups. Relative risks (RRs) and 95% CIs were estimated with log binomial regression to adjust for confounding. RESULTS: Of 2,292 participants analyzed, 720 (31.4%) received labetalol, 417 (18.2%) received nifedipine, and 1,155 (50.4%) received no treatment. The mean gestational age at enrollment was 10.5±3.7 weeks; nearly half of participants (47.5%) identified as non-Hispanic Black; and 44.5% used aspirin. The primary outcome occurred in 217 (30.1%), 130 (31.2%), and 427 (37.0%) in the labetalol, nifedipine, and standard care groups, respectively. Risk of the primary outcome was lower among those receiving treatment (labetalol use vs standard adjusted RR 0.82, 95% CI, 0.72-0.94; nifedipine use vs standard adjusted RR 0.84, 95% CI, 0.71-0.99), but there was no significant difference in risk when labetalol was compared with nifedipine (adjusted RR 0.98, 95% CI, 0.82-1.18). There were no significant differences in SGA or serious adverse events between participants receiving labetalol and those receiving nifedipine. CONCLUSION: No significant differences in predetermined maternal or neonatal outcomes were detected on the basis of the use of labetalol or nifedipine for treatment of chronic hypertension in pregnancy. CLINICAL TRIAL REGISTRATION: ClinicalTrials.gov, NCT02299414.

RESUMEN

OBJECTIVE: To compare differences in postpartum blood pressure (BP) control (BP below 140/90 mm Hg) for participants with hypertension randomized to receive antihypertensive treatment compared with no treatment during pregnancy. METHODS: This study was a planned secondary analysis of a multicenter, open-label, randomized controlled trial (The CHAP [Chronic Hypertension and Pregnancy] trial). Pregnant participants with mild chronic hypertension (BP below 160/105 mm Hg) were randomized into two groups: active (antihypertensive treatment) or control (no treatment unless severe hypertension, BP 160/105 mm Hg or higher). Study outcomes were BP control below 140/90 mm Hg (primary) and medication nonadherence based on a composite score threshold (secondary) at the 6-week postpartum follow-up visit. Participants without follow-up BP measurements were excluded from analysis of the BP control outcome. Participants without health care professional-prescribed antihypertensives at delivery were excluded from the analysis of the adherence outcome. Multivariable logistic regression was used to adjust for potential confounders. RESULTS: Of 2,408 participants, 1,684 (864 active, 820 control) were included in the analysis. A greater percentage of participants in the active group achieved BP control (56.7% vs 51.5%; adjusted odds ratio [aOR] 1.22, 95% CI, 1.00-1.48) than in the control group. Postpartum antihypertensive prescription was higher in the active group (81.7% vs 58.4%, P<.001), and nonadherence did not differ significantly between groups (aOR 0.81, 95% CI, 0.64-1.03). CONCLUSION: Antihypertensive treatment of mild chronic hypertension during pregnancy was associated with better BP control below 140/90 mm Hg in the immediate postpartum period.

RESUMEN

OBJECTIVE: To investigate the optimal gestational age to deliver pregnant people with chronic hypertension to improve perinatal outcomes. METHODS: We conducted a planned secondary analysis of a randomized controlled trial of chronic hypertension treatment to different blood pressure goals. Participants with term, singleton gestations were included. Those with fetal anomalies and those with a diagnosis of preeclampsia before 37 weeks of gestation were excluded. The primary maternal composite outcome included death, serious morbidity (heart failure, stroke, encephalopathy, myocardial infarction, pulmonary edema, intensive care unit admission, intubation, renal failure), preeclampsia with severe features, hemorrhage requiring blood transfusion, or abruption. The primary neonatal outcome included fetal or neonatal death, respiratory support beyond oxygen mask, Apgar score less than 3 at 5 minutes, neonatal seizures, or suspected sepsis. Secondary outcomes included intrapartum cesarean birth, length of stay, neonatal intensive care unit admission, respiratory distress syndrome (RDS), transient tachypnea of the newborn, and hypoglycemia. Those with a planned delivery were compared with those expectantly managed at each gestational week. Adjusted odds ratios (aORs) with 95% CIs are reported. RESULTS: We included 1,417 participants with mild chronic hypertension; 305 (21.5%) with a new diagnosis in pregnancy and 1,112 (78.5%) with known preexisting hypertension. Groups differed by body mass index (BMI) and preexisting diabetes. In adjusted models, there was no association between planned delivery and the primary maternal or neonatal composite outcome in any gestational age week compared with expectant management. Planned delivery at 37 weeks of gestation was associated with RDS (7.9% vs 3.0%, aOR 2.70, 95% CI, 1.40-5.22), and planned delivery at 37 and 38 weeks was associated with neonatal hypoglycemia (19.4% vs 10.7%, aOR 1.97, 95% CI, 1.27-3.08 in week 37; 14.4% vs 7.7%, aOR 1.82, 95% CI, 1.06-3.10 in week 38). CONCLUSION: Planned delivery in the early-term period compared with expectant management was not associated with a reduction in adverse maternal outcomes. However, it was associated with increased odds of some neonatal complications. Delivery timing for individuals with mild chronic hypertension should weigh maternal and neonatal outcomes in each gestational week but may be optimized by delivery at 39 weeks.

RESUMEN

INTRODUCTION: Preeclampsia (PE) affects 2-8% of all pregnancies, and is the leading cause of maternal and fetal morbidity and mortality. We reported on pathophysiological changes in placenta mesenchymal stem cells (P-MSCs) in PE. P-MSCs can be isolated from different layers of the placenta at the interface between the fetus and mother. The ability of MSCs from other sources to be immune licensed as immune suppressor cells indicated that P-MSCs could mitigate fetal rejection. Acetylsalicylic acid (aspirin) is indicated for treating PE. Indeed, low-dose aspirin is recommended to prevent PE in high risk patients. METHODS: We conducted robust computational analyses to study changes in gene expression in P-MSCs from PE and healthy term pregnancies as compared with PE-MSCs treated with low dose acetyl salicylic acid (LDA). Confocal microscopy studied phospho-H2AX levels in P-MSCs. RESULTS: We identified changes in >400 genes with LDA, similar to levels of healthy pregnancy. The top canonical pathways that incorporate these genes were linked to DNA repair damage - Basic excision repair (BER), Nucleotide excision repair (NER) and DNA replication. A role for the sumoylation (SUMO) pathway, which could regulate gene expression and protein stabilization was significant although reduced as compared to BER and NER pathways. Labeling for phopho-H2AX indicated no evidence of double strand break in PE P-MSCs. DISCUSSION: The overlapping of key genes within each pathway suggested a major role for LDA in the epigenetic landscape of PE P-MSCs. Overall, this study showed a new insight into how LDA reset the P-MSCs in PE subjects around the DNA.

RESUMEN

OBJECTIVE: To evaluate the effect of comorbidities and induction of labor (IOL) on the cesarean delivery (CD) rate in an obese nulliparous cohort. STUDY DESIGN: This was a retrospective review of medical records of patients who delivered at our institution from January 1, 2010, to January 18, 2011. Nulliparous patients were identified with a body mass index of ≥ 30.0 kg/m2. The rates of IOL and CD for patients with a comorbidity were compared with those patients without a comorbidity. RESULTS: Among 1908 patients, 105 met inclusion criteria. The CD rate was significantly higher in the comorbid group (58.5%) than in the control group (34.6%) [odds ratio (OR) 2.66, 95% confidence interval (CI) 1.21 to 5.87, p = 0.019] [corrected].The IOL rate was significantly higher in the comorbid group (71.7% versus 15.4%; OR 13.93, 95% CI 5.33 to 36.46, p < 0.0001). Preeclampsia (44.7%) was the most common indication for IOL in the comorbid group, whereas postterm pregnancy (50%) was the most common indication in the control group. CONCLUSION: The CD rate in obese women with comorbidities is higher than that of obese women without comorbidity. These results suggest that the higher IOL rate and subsequent failed induction in obese women with comorbidities is a significant factor contributing to this association.

RESUMEN

OBJECTIVE: The objective of this study was to determine the relationship between maternal antepartum antibiotic administration and antibiotic resistance patterns in preterm neonates admitted to the neonatal intensive care unit (NICU). METHODS: This was a retrospective cohort study of women and their preterm neonates delivered at a single tertiary care center over a 5-year period. Women and neonates were included if they delivered between 23 weeks 0 days and 28 weeks 6 days of gestation and neonates were admitted to the NICU. Subjects were excluded if there was incomplete antibiotic administration data or incomplete laboratory or bacterial culture data for either mothers or neonates. Data collected from maternal and neonatal charts included the type, duration, and total number of antibiotics administered to subjects, neonatal culture results within the first 7 days of life, and bacterial antibiotic resistance information. Women with neonates that cultured positive for bacteria demonstrating antibiotic resistance were compared to those whose neonates did not have antibiotic-resistant bacteria. RESULTS: 79 women with 90 neonates met inclusion criteria. Of the 79 women, 71 (89.9%) received at least 1 antibiotic antepartum. 14 neonatal bacterial isolates were resistant to at least 1 antibiotic. Antibiotic-resistant bacteria were present in 11 neonates; 3 neonates had more than 1 resistant bacteria cultured. The most common resistant bacteria cultured were Coagulase-negative Staphylococcus (6/14, 42.9%), S. aureus (3/14, 21.4%), and E. coli (2/14, 14.3%). Enterobacter spp (2) and Klebsiella pneumoniae (1) made up the remainder. Of the 11 neonates with resistant bacteria isolated, 10 of their mothers received antibiotics antepartum. Neonates with antibiotic-resistant bacterial isolates were more likely to be born at lower gestational ages (24.6 vs 25.9 weeks, p = .013) and have lower mean birth weights (679.5 vs 849.3 g, p = .009) than those without resistant bacteria. In 8 of 11 (73%) neonates with resistant bacteria, the mother received an antibiotic to which the bacteria cultured were resistant: 6 coagulase-negative Staphylococcus, 1 MRSA, and 1 S. aureus. CONCLUSIONS: Although preterm neonates are often treated for presumed sepsis, they infrequently have positive bacterial cultures. In this study, those that had positive bacterial cultures for resistant bacteria were born at earlier gestational ages and had lower birth weights. These bacteria cultured in neonates are likely to be resistant to antibiotics received by mothers in the antepartum period. Careful selection of maternal and neonatal antibiotics in the preterm setting with consideration for local antibiotic resistance patterns is suggested.

RESUMEN

Background: Ornithine transcarbamylase deficiency (OTCD) is a rare disorder of the urea cycle that obstetricians should be aware of in order to guide management for pregnant carriers of the X-linked gene that causes the condition. Cases: We present the pregnancy management and outcomes of two women with OTCD. The particular manifestations of the disease drive antenatal, intrapartum and postpartum management. Conclusion: Preconception counseling, early prenatal diagnostics and multidisciplinary intrapartum and postpartum management plans contribute to improved outcomes for patients.

RESUMEN

Preeclampsia (PE) is a pregnancy-specific disease, occurring in ~ 2-10% of all pregnancies. PE is associated with increased maternal and perinatal morbidity and mortality, hypertension, proteinuria, disrupted artery remodeling, placental ischemia and reperfusion, and inflammation. The mechanism of PE pathogenesis remains unresolved explaining limited treatment. Aspirin is used to reduce the risk of developing PE. This study investigated aspirin's effect on PE-derived placenta mesenchymal stem cells (P-MSCs). P-MSCs from chorionic membrane (CM), chorionic villi, membranes from the maternal and amniotic regions, and umbilical cord were similar in morphology, phenotype and multipotency. Since CM-derived P-MSCs could undergo long-term passages, the experimental studies were conducted with this source of P-MSCs. Aspirin (1 mM) induced significant functional and transcriptomic changes in PE-derived P-MSCs, similar to healthy P-MSCs. These include cell cycle quiescence, improved angiogenic pathways, and immune suppressor potential. The latter indicated that aspirin could induce an indirect program to mitigate PE-associated inflammation. As a mediator of activating the DNA repair program, aspirin increased p53, and upregulated genes within the basic excision repair pathway. The robust ability for P-MSCs to maintain its function with high dose aspirin contrasted bone marrow (M) MSCs, which differentiated with eventual senescence/aging with 100 fold less aspirin. This difference cautions how data from other MSC sources are extrapolated to evaluate PE pathogenesis. Dysfunction among P-MSCs in PE involves a network of multiple pathways that can be restored to an almost healthy functional P-MSC. The findings could lead to targeted treatment for PE.

RESUMEN

We sought to determine if gravidas with pregestational diabetes mellitus (DM) are at increased risk for asymptomatic bacteriuria (ASB) compared with nondiabetic gravidas. This is a retrospective case-control study of 150 pregnant patients with pregestational DM and 294 nondiabetic controls. Rates of ASB and any colony count of group B streptococcus (GBS) bacteriuria were reviewed. The incidence of ASB among pregestational diabetics was higher compared with nondiabetic gravidas (18% versus 8.2%, odds ratio [OR] 2.47, 95% confidence interval [CI] 1.37 to 4.45). GBS was the most common organism in diabetic gravidas (26%). There was no difference in incidence of ASB recurrence (OR 1.26, 95% CI 0.37 to 4.36), but antibiotic resistance was higher in the control group (OR 0.28, 95% CI 0.09 to 0.91). Diabetic gravidas with ASB or any level of GBS bacteriuria had higher hemoglobin A (1c) values compared with diabetics without ASB (8.31 +/- 1.89 versus 7.31 +/- 1.84, P = 0.0035). Our results demonstrate that gravidas with DM are at increased risk of ASB including GBS bacteriuria compared with non-diabetic gravidas.

RESUMEN

Cardiac tamponade is an uncommon but life-threatening emergency that may occur in pregnant women. There is a plethora of causes, but prompt diagnosis and intervention is imperative to optimize both maternal and fetal outcomes. We report on a case of a large pericardial effusion leading to cardiac tamponade occurring in the 32nd week of gestation in a previously healthy woman. Rapid recognition and a multidisciplinary team meeting resulted in a therapeutic pericardial window and drainage and relief of symptoms. The woman underwent an uncomplicated repeat cesarean delivery at term with a positive neonatal outcome. This case highlights the importance of a rapid diagnosis and a team-based approach to managing a complex medical condition like cardiac tamponade in pregnancy.

RESUMEN

BACKGROUND: Previous research has focused mainly on neonatal outcomes associated with preterm and periviable delivery, but maternal outcomes with preterm delivery are less well described. OBJECTIVE: This study aimed to determine if early preterm delivery results in an increase in maternal morbidity. STUDY DESIGN: This is a retrospective cohort study conducted at a tertiary care center over a 5-year time period. Subjects were women identified by review of neonatal intensive care unit admission logs. Women were included if they delivered between 23 0/7 and 28 6/7 weeks' gestation and their neonate was admitted to the neonatal intensive care unit. The prevalence of maternal morbidities was assessed, including blood transfusion, maternal infection, placental abruption, postpartum depression or positive depression screen, hemorrhage, and prolonged maternal postpartum hospitalization. A composite outcome comprising blood transfusion, maternal infectious morbidity, placental abruption, and postpartum depression was developed. Outcomes for women who delivered between 23 0/7 and 25 6/7 weeks' gestation (early group) and 26 0/7 and 28 6/7 weeks' gestation (late group) were compared. Multivariate logistic regression analysis was performed to evaluate contributors to the composite morbidity, controlling for confounding. RESULTS: A total of 82 women met the inclusion criteria: 38 in the early group and 44 in the late group. Maternal demographics were similar between the groups. The early group was significantly more likely to experience composite maternal morbidity (60.5% vs 27.3%; P=.004) and infection (42.1% vs 13.6%; P=.006). Regression analysis determined that delivery at a later gestational age was associated with lower rates of composite morbidity (odds ratio, 0.6; 95% confidence interval, 0.41-0.83). CONCLUSION: In this study, data suggest that maternal morbidity is higher with delivery at periviable gestational ages. Composite morbidity and maternal infection were more frequent in women who delivered at less than 26 weeks' gestation. The management of women at risk for delivery at early gestational ages should include a discussion of increased maternal complications.

RESUMEN

OBJECTIVES: Women with hypertensive disorders of pregnancy should have a blood pressure evaluation no later than 7-10 days after delivery. The objective of this study was to identify the factors associated with patient attendance at the postpartum blood pressure follow-up visit. STUDY DESIGN: This was a retrospective cohort study of postpartum women who had a hypertensive disorder of pregnancy. Postpartum follow-up rates were recorded, and characteristics of women who attended a postpartum visit for blood pressure evaluation were compared to women who did not return for the visit. Multiple logistic regression was performed. MAIN OUTCOME MEASURES: Characteristics of women who returned for a blood pressure visit. RESULTS: There were 378 women who met inclusion criteria; 193(51.1%) attended the blood pressure visit. Women who returned were older and more likely to have preeclampsia, severe features, magnesium sulfate use, or severe hypertension during hospitalization. They were less likely to have gestational hypertension. Adjusted analysis demonstrated that black/non-Hispanic women (OR 0.53, 95% CI 0.34-0.83), the presence of any preeclampsia diagnosis (OR 2.19, 95% CI 1.03-4.81), and whether the woman underwent a cesarean delivery (OR 3.06, 95% CI 1.85-5.14) remained significant factors in predicting adherence. CONCLUSIONS: Women who returned for a blood pressure visit were more likely to have had significant hypertensive disease or a cesarean delivery. Non-Hispanic black women had the lowest rate of follow-up. Given black women have the highest rates of maternal morbidity and mortality nationwide, effective interventions to increase follow-up for them are needed.

RESUMEN

OBJECTIVE: The objective of the study was to review pregnancy and neonatal outcomes among perinatally infected pregnant patients at our institution. STUDY DESIGN: A retrospective review of maternal and neonatal records for all 10 perinatally infected adolescents between 1997 and 2007 was performed. Demographics, CD4 and viral load, antiretroviral treatment, medical comorbidities, pregnancy outcomes, and neonatal human immunodeficiency virus (HIV) status were abstracted. RESULTS: The median age at first pregnancy was 18.5 years and 70% were African American. The most common comorbidities were hematologic abnormalities (70%) and cervical dysplasia/sexually transmitted infections (STIs) (80%). Initial median CD4 and viral load were 317 cells/mm(3) and 8780 copies/mL, respectively. The median gestational age at delivery was 38 weeks. The most common obstetrical complications were preeclampsia (23%) and premature rupture of membranes/preterm delivery (31%). The cesarean delivery (CD) rate was 62%, with HIV as the indication in 75%. All infants were born alive; 1 was HIV infected. CONCLUSION: Despite high rates of STIs, CD, preterm delivery, and hypertensive disorders, perinatal outcomes were favorable.

RESUMEN

BACKGROUND: Glutaric aciduria type II is a rare disorder affecting the metabolism of fatty acid oxidation and several mitochondrial dehydrogenase enzymes. Narcolepsy and cataplexy is a disorder affecting sleep cycles and rapid eye movement activity. There is little information on outcome or management for either disorder in pregnancy. CASE: This is a case of a 16-year-old with glutaric aciduria type II and narcolepsy with cataplexy, treated with L-carnitine, riboflavin, fluoxetine, and modafinil during pregnancy. Intrapartum management included intravenous carnitine administration, and the patient underwent cesarean delivery at term without complication. CONCLUSION: This inborn error of metabolism and sleep disorder can be effectively treated during pregnancy with nutritional supplementation and stimulants. Because of the risk of cataplexy during labor, cesarean delivery is recommended to minimize the patient's risk.

RESUMEN

PURPOSE: Procalcitonin (PCT) is an acute-phase protein that has been infrequently studied in amniotic fluid. We sought to determine if PCT levels measured in amniotic fluid samples at the time of genetic amniocentesis are predictive of preterm delivery. MATERIALS AND METHODS: A retrospective cohort study was performed on all women presenting for genetic amniocentesis between 15-23 weeks of pregnancy at our institution from 2011 to 2013 with stored amniotic fluid samples. PCT protein levels were measured in the samples by enzyme-linked immunosorbent assay (ELISA). PCT levels in women who delivered less than 37 weeks versus those who delivered at or after 37 week were compared. Mann-Whitney test was used. RESULTS: Eighty-seven samples were available for analysis and of these eight (9.2%) were from patients who delivered preterm. Sixty-two (70%) had PCT levels below the lower limit of quantification, which was 25 pg/mL. Median PCT levels did not differ between the preterm and term group [20.4 pg/mL (range 0-82.8) and 20.2 pg/mL (range 0-198.4), respectively, p = .95]. CONCLUSION: In asymptomatic women undergoing genetic amniocentesis in this cohort, procalcitonin levels were low to undetectable and did not correlate with risk of subsequent preterm birth.
