Objectives: To estimate the incidence and risk of complications associated with a fetal scalp electrode and to determine whether its application in the setting of operative vaginal delivery was associated with increased neonatal morbidity.Design: Retrospective cohort study.Setting: Twelve clinical centers with 19 hospitals across nine American Congress of Obstetricians and Gynecologists US districts.Population: Women in the USA.Methods: We evaluated 171 698 women with singleton deliveries ≥ 23 weeks of gestation in a secondary analysis of the Consortium on Safe Labor study between 2002 and 2008, after excluding conditions that precluded fetal scalp electrode application such as prelabour caesarean delivery. Secondary analysis limited to operative vaginal deliveries ≥ 34 weeks of gestation was also performed.Main Outcome Measures: Incidences and adjusted odds ratios with 95% confidence intervals of neonatal complications were calculated, controlling for maternal characteristics, delivery mode and pregnancy complications.Results: Fetal scalp electrode was used in 37 492 (22%) of deliveries. In non-operative vaginal delivery, fetal scalp electrode was associated with increased risk of injury to scalp due to birth trauma (1.2% versus 0.9%; adjusted odds ratios 1.62; 95% confidence intervals 1.41-1.86) and cephalohaematoma (1.0% versus 0.9%; adjusted odds ratios 1.57; 95% confidence intervals 1.36-1.83). Neonatal complications were not significantly different comparing fetal scalp electrode with vacuum-assisted vaginal delivery and vacuum-assisted vaginal delivery alone or comparing fetal scalp electrode with forceps-assisted vaginal delivery and forceps-assisted vaginal delivery alone.Conclusions: We found increased neonatal morbidity with fetal scalp electrode though the absolute risk was very low. It is possible that these findings reflect an underlying indication for its use. Our findings support the use of fetal scalp electrodes when clinically indicated.Tweetable Abstract: Neonatal risks associated with fetal scalp electrode use were low (injury to scalp 1.2% and cephalohaematoma 1.0%).

Objective: To estimate the effect of diabetes group prenatal care on rates of preterm birth and large for gestational age (LGA) among patients with diabetes in pregnancy compared with individual diabetes prenatal care., Data Sources: We searched Ovid Medline (1946-), Embase.com (1947-), Scopus (1823-), Cochrane Central Register of Controlled Trials, and ClinicalTrials.gov., Methods of Study Selection: We searched electronic databases for randomized controlled trials (RCTs) and observational studies comparing diabetes group prenatal care with individual care among patients with type 2 diabetes mellitus or gestational diabetes mellitus (GDM). The primary outcomes were preterm birth before 37 weeks of gestation and LGA (birth weight at or above the 90th percentile). Secondary outcomes were small for gestational age, cesarean delivery, neonatal hypoglycemia, neonatal intensive care unit admission, breastfeeding at hospital discharge, long-acting reversible contraception (LARC) uptake, and 6-week postpartum visit attendance. Secondary outcomes, limited to the subgroup of patients with GDM, included rates of GDM requiring diabetes medication (A2GDM) and completion of postpartum oral glucose tolerance testing (OGTT). Heterogeneity was assessed with the Cochran Q test and I2 statistic. Random-effects models were used to calculate pooled relative risks (RRs) and weighted mean differences., Tabulation, Integration, and Results: Eight studies met study criteria and were included in the final analysis: three RCTs and five observational studies. A total of 1,701 patients were included in the pooled studies: 770 (45.3%) in diabetes group prenatal care and 931 (54.7%) in individual care. Patients in diabetes group prenatal care had similar rates of preterm birth compared with patients in individual care (seven studies: pooled rates 9.5% diabetes group prenatal care vs 11.5% individual care, pooled RR 0.77, 95% CI, 0.59-1.01), which held for RCTs and observational studies. There was no difference between diabetes group prenatal care and individual care in rates of LGA overall (four studies: pooled rate 16.7% diabetes group prenatal care vs 20.2% individual care, pooled RR 0.93, 95% CI, 0.59-1.45) or by study type. Rates of other secondary outcomes were similar between diabetes group prenatal care and individual care, except patients in diabetes group prenatal care were more likely to receive postpartum LARC (three studies: pooled rates 46.1% diabetes group prenatal care vs 34.1% individual care, pooled RR 1.44, 95% CI, 1.09-1.91). When analysis was limited to patients with GDM, there were no differences in rates of A2GDM or postpartum visit attendance, but patients in diabetes group prenatal care were significantly more likely to complete postpartum OGTT (five studies: pooled rate 74.0% diabetes group prenatal care vs 49.4% individual care, pooled RR 1.58, 95% CI, 1.19-2.09)., Conclusion: Patients with type 2 diabetes and GDM who participate in diabetes group prenatal care have similar rates of preterm birth, LGA, and other pregnancy outcomes compared with those who participate in individual care; however, they are significantly more likely to receive postpartum LARC, and those with GDM are more likely to return for postpartum OGTT., Systematic Review Registration: PROSPERO, CRD42021279233., Competing Interests: Financial Disclosure Stacey Ehrenberg Buchner reports receiving payment from Dexcom, Inc.

Early diabetes screening is recommended for high-risk pregnant women risk via a 1-hour glucose challenge test (1-hour GCT). Hemoglobin A1c (HbA1c) can be obtained with initial obstetric laboratories. We sought to examine the relationship between HbA1c and 1-hour GCT for early diabetes screening in pregnancy. This is a retrospective cohort study of 204 high-risk pregnant women who underwent early HbA1c and 1-hour GCT. Simple logistic regression analysis was performed to predict abnormal 1-hour GCT and diagnosis of diabetes using HbA1c. A total of 158 (77.5%), 44 (21.5%), and 2 (1%) women had HbA1c of less than 5.7, 5.7 to 6.4, and 6.5% or higher, respectively. Seven of 158 (4.4%) women with HbA1c less than 5.7% and 8 of 44 (18.2%) with HbA1c of 5.7 to 6.4% had a diagnosis of diabetes. A positive correlation between early HbA1c and 1-hour GCT was detected. Logistic regression showed HbA1c significantly predicted the risk of diabetes but was not a good predictor of abnormal 1-hour GCT. HbA1c of 5.5% or less had a 97% or higher negative predictive value for early diabetes in pregnancy. There is a positive correlation between HbA1c and 1-hour GCT for the early screening of diabetes in pregnancy. Women with early HbA1c ≤ 5.5% could forego further testing in early pregnancy., Competing Interests: Conflict of Interest None declared., (The Author(s).

Background: Preterm premature rupture of membranes accounts for approximately one-quarter of all preterm deliveries and occurs in 2% to 3% of all pregnancies. With subclinical infection being a suspected cause of preterm premature rupture of membranes, the administration of prophylactic antibiotics is an accepted standard of care to extend the latency period. Historically, erythromycin was used in the antibiotic regimen recommended for women with preterm premature rupture of membranes during expectant management; however, azithromycin has recently been shown to be a suitable alternative., Objective: This study aimed to evaluate whether extended azithromycin administration affects the latency time in preterm premature rupture of membranes., Study Design: This was a retrospective multi-institutional cohort study in Washington, District of Columbia, of patients admitted from January 2012 to December 2019 with preterm premature rupture of membranes of singleton pregnancies between 23 0/7 and 33 6/7 weeks of gestation. Patients were excluded if they had multiple pregnancies, had an allergy to penicillin or macrolides, were in labor, had suspected placental abruptions, had overt chorioamnionitis, or had nonreassuring fetal status on presentation indicating the need for prompt delivery. Patients that received limited azithromycin administration (<2 days) and patients that received extended azithromycin administration (7 days) were compared. All patients otherwise received the institutional standard of 2 days of intravenous ampicillin followed by 5 days of oral amoxicillin. The primary outcome was length of gestational latency, defined as the time from membrane rupture to delivery. The selective secondary outcomes that were evaluated were rates of chorioamnionitis and adverse neonatal outcomes, including sepsis, respiratory distress, necrotizing enterocolitis, intraventricular hemorrhage, and neonatal death., Results: During the study period, 416 cases of preterm premature rupture of membranes were identified. Of the 287 patients who met the inclusion criteria, 165 (57.5%) received limited azithromycin administration, and 122 (42.5%) received extended azithromycin administration. Adjusted median gestational latency was significantly longer for patients who received extended azithromycin administration, extended by >3 days (2.6 days [interquartile range, 2.2-3.1] for limited azithromycin administration vs 5.8 days [interquartile range, 4.8-6.9] for extended azithromycin administration; P <.001). Neonatal secondary outcome evaluation was performed on 216 cases (76%). There was no difference in chorioamnionitis or adverse neonatal outcomes between the 2 groups., Conclusion: Among patients with preterm premature rupture of membranes, extended azithromycin administration was associated with increased latency, without any effect on other maternal or neonatal outcomes., (© 2023 The Authors.)

Objective: To determine the expression profile of microRNAs in the peripheral blood of pregnant women with preterm premature rupture of membranes (PPROM) compared to that of healthy pregnant women., Study Design: This was a pilot study with case-control design in pregnant patients enrolled between January 2017 and June 2019. Patients with healthy pregnancies and those affected by PPROM between 20- and 33+6 weeks of gestation were matched by gestational age and selected for inclusion to the study. Patients were excluded for multiple gestation and presence of a major obstetrical complication such as preeclampsia, diabetes, fetal growth restriction and stillbirth. A total of ten (n = 10) controls and ten (n = 10) patients with PPROM were enrolled in the study. Specimens were obtained before administration of betamethasone or intravenous antibiotics. MicroRNA expression was analyzed for 800 microRNAs in each sample using the NanoString nCounter Expression Assay. Differential expression was calculated after normalization and log2- transformation using the false discovery rate (FDR) method at an alpha level of 5%., Results: Demographic characteristics were similar between the two groups. Of the 800 miRNAs analyzed, 116 were differentially expressed after normalization. However, only four reached FDR-adjusted statistical significance. Pregnancies affected by PPROM were characterized by upregulation of miR-199a-5p, miR-130a-3p and miR-26a-5p and downregulation of miR-513b-5p (FDR adjusted p-values <0.05). The differentially expressed microRNAs participate in pathways associated with altered collagen and matrix metalloprotease expression in the extracellular matrix., Conclusion: Patients with PPROM have a distinct peripheral blood microRNA profile compared to healthy pregnancies as measured by the NanoString Expression Assay., Competing Interests: The authors have declared that no competing interests exist.

Background: The process by which drugs leave the bloodstream to enter the skin compartments is important in determining appropriate routes of delivery and developing more efficacious medications. We conducted a general literature review on percutaneous egression mechanisms., Summary: Studies demonstrate that the stratum corneum (SC) is a compartment for systemically delivered drugs. Upon reviewing the available literature, it became apparent that there may be multiple mechanisms of percutaneous egression dependent upon drug physiochemical properties. These mechanisms include, but are not limited to, desquamation, sebum secretion, sweat transport, and passive diffusion. While drugs often utilize one major pathway, it is possible that all mechanisms may play a role to varying extents., Key Messages: Available literature suggests that hydrophilic substances tended to travel from blood to the upper layers of the skin via sweat, whereas lipophilic substances utilized sebum secretion to reach the SC. Upon reaching the skin surface, the drugs spread laterally before penetrating back into the skin as if they were topically administered. More data are warranted to identify additional percutaneous egression mechanisms, precise drug action sites, and accelerate drug development., (© 2022 The Author(s). Published by S.

Objective: Postpartum hypertension is a leading cause of readmission in the postpartum period. We aimed to examine the prevalence of racial/ethnic differences in postpartum readmission due to hypertension in women with antepartum pregnancy-associated hypertension., Study Design: This was a multi-institutional retrospective cohort study of all women with antepartum pregnancy-associated hypertension diagnosed prior to initial discharge from January 2009 to December 2016. Antepartum pregnancy-associated hypertension, such as gestational hypertension, preeclampsia (with or without severe features), hemolysis, elevated liver enzyme, low platelet (HELLP) syndrome, and eclampsia was diagnosed based on American College of Obstetricians and Gynecologists Task Force definitions. Women with chronic hypertension and superimposed preeclampsia were excluded. Our primary outcome was postpartum readmission defined as a readmission due to severe hypertension within 6 weeks of postpartum. Risk factors including maternal age, gestational age at admission, insurance, race/ethnicity (self-reported), type of antepartum pregnancy-associated hypertension, marital status, body mass index (kg/m 2 ), diabetes (gestational or pregestational), use of antihypertensive medications, mode of delivery, and postpartum day 1 systolic blood pressure levels were examined. Multivariable logistic regression models were performed to calculate adjusted odds ratios (aORs) and 95% confidence intervals (95% CIs)., Results: Of 4,317 women with pregnancy-associated hypertension before initial discharge, 66 (1.5%) had postpartum readmission due to hypertension. Risk factors associated with postpartum readmission due to hypertension included older maternal age (aOR = 1.44; 95% CI: 1.20-1.73 for every 5 year increase) and non-Hispanic black race (aOR = 2.12; 95% CI: 1.16-3.87)., Conclusion: In women with pregnancy-associated hypertension before initial discharge, non-Hispanic black women were at increased odds of postpartum readmission due to hypertension compared with non-Hispanic white women., Competing Interests: None declared., (Thieme.

Background: Maternal and neonatal outcomes associated with duration of arrest of dilation beyond 4 hours are not well known. In addition, the current definition of arrest does not consider the degree of cervical dilation (6 cm vs 7 cm vs 8 cm vs 9 cm) when arrest occurs., Objective: We sought to examine maternal and neonatal outcomes in nulliparous women who achieved the active phase of labor according to the duration they required to achieve a cervical change of at least 1 cm (<4 hours vs 4-5.9 hours vs ≥6 hours) beginning at 6, 7, 8 and 9 cm., Study Design: This was a retrospective cohort study of nulliparous women with term singleton cephalic pregnancies in spontaneous or induced active labor (≥6 cm). To evaluate the effect of labor duration on maternal and fetal outcomes at different degrees of cervical dilation, we categorized women based on time intervals they required to achieve a cervical change of at least 1 cm after membrane rupture ("<4 hours," "4-5.9 hours," and "≥6 hours"), and we correlated each time interval with referent cervical dilation status (6 cm, 7 cm, 8 cm, and 9 cm). Maternal and neonatal outcomes were analyzed according to the duration to progress at least 1 cm starting from each degree of cervical dilation. Our primary outcome was a composite of neonatal outcomes, including intensive care unit admission, neonatal death, seizure, ventilator use, birth injury, and neonatal asphyxia. In addition, we examined maternal outcomes. Adjusted odds ratios with 95% confidence intervals were calculated, controlling for predefined covariates., Results: Of 31,505 nulliparous women included in this study, 13,142 (42%), 10,855 (34%), 11,761 (37%), and 17,049 (54%) reached documented cervical dilation of 6, 7, 8, and 9 cm, respectively. At cervical dilation of 6 or 7 cm, the arrest of dilation of <4 hours compared with arrest of dilation of 4 to 5.9 hours was associated with decreased risks of adverse maternal outcomes. When cervical dilation was 8 or 9 cm, arrest of dilation of <4 hours compared with arrest of dilation of 4 to 5.9 hours was associated with decreased risks of adverse maternal and neonatal outcomes. For example, women starting at a cervical dilation of 8 cm who required <4 hours to achieve a cervical change of 1 cm compared with those who required 4 to 5.9 hours had lower rates of cesarean delivery (adjusted odds ratio, 0.40; 95% confidence interval, 0.28-0.55), chorioamnionitis (adjusted odds ratio, 0.42; 95% confidence interval, 0.29-0.60), and the neonatal composite outcome (adjusted odds ratio, 0.51; 95% confidence interval, 0.36-0.72)., Conclusion: When cervical dilation is 6 or 7 cm, allowing arrest of dilation of ≥4 hours is reasonable because it was not associated with increased risks of adverse neonatal outcomes. When cervical dilation is 8 or 9 cm, the benefit of allowing arrest of dilation of ≥4 hours should be balanced against the risk of adverse maternal and neonatal outcomes., (Copyright © 2021 Elsevier Inc.

Objective: To evaluate whether viewing an educational video on pain management reduces opioid use after cesarean delivery., Methods: We conducted a randomized, controlled trial of women aged 18 years or older who underwent cesarean delivery at a tertiary care center. Eligible women were randomized in a 1:1 ratio to usual discharge pain medication instructions plus an educational video on pain management or to usual discharge pain medication instructions alone. All women received the same opioid prescription at discharge: Twenty 5-mg oxycodone tablets. Participants were contacted at 7 days and at 14 days after delivery to assess the number of oxycodone tablets used, adjunct medication (acetaminophen and ibuprofen) use, pain scores, and overall satisfaction of pain control. The primary outcome was the number of oxycodone tablets used from discharge through postpartum day 14. A sample size of 23 per group (n=46) was planned to detect a 25% difference in mean number of oxycodone tablets used between groups, as from 20 to 15., Results: From July 2019 through December 2019, 61 women were screened and 48 were enrolled-24 in each group. Women who viewed the educational video used significantly fewer opioid tablets from discharge through postpartum day 14 compared with women who received usual pain medication instructions (median 1.5, range 0-20 vs median 10, range 0-24, P<.001). Adjunct medication use, pain scores, and satisfaction with pain control did not differ significantly between groups., Conclusion: Among women who underwent cesarean delivery, viewing an educational video on pain management reduced postdischarge opioid use., Clinical Trial Registration: ClinicalTrials.gov, NCT03959969., Competing Interests: Financial Disclosure The authors did not report any potential conflicts of interest., (Copyright © 2021 by the American College of Obstetricians and Gynecologists.

Background: The Maternal-Fetal Triage Index is a 5-level system to facilitate the care of pregnant women seeking care in an obstetrical triage unit (priority 1 being the highest acuity and priority 5 being the lowest acuity). Although the American College of Obstetricians and Gynecologists recommends implementing labor and delivery triage tools, it remains unclear whether the Maternal-Fetal Triage Index facilitates the timely evaluation of high-acuity pregnant women., Objective: We sought to examine the duration of a labor and delivery triage evaluation before and after the implementation of the Maternal-Fetal Triage Index. We also sought to examine the duration of a labor and delivery triage evaluation according to priority levels by the Maternal-Fetal Triage Index., Study Design: This was a retrospective quality improvement study of all women presenting to an urban, tertiary labor and delivery triage unit at 16 weeks' gestation or later from December 2017 to February 2018 (historical cohort) and December 2018 to February 2019 (study cohort). As part of a quality improvement initiative, the Maternal-Fetal Triage Index was implemented in the labor and delivery unit in May 2018. All registered nurses who worked in the labor and delivery unit completed a formal education course and assigned the priority levels at the time of triage presentation. The primary outcome was the duration of a labor and delivery triage evaluation, which was defined as the time interval from triage presentation to the completion of history and physical examination in the electronic medical record. Secondary outcomes included the rates of labor and delivery unit admissions., Results: There were 1305 and 1374 women in the historical cohort and study cohort, respectively. The duration of labor and delivery triage evaluation was longer for the study cohort than for the historical cohort (64 minutes vs 61 minutes; P=.02). Of the 1374 women in the study cohort, there were 28 (2%), 290 (21%), 459 (33%), 462 (34%), and 135 (10%) women with priority levels 1, 2, 3, 4, and 5 assigned, respectively. Women with a higher priority according to the Maternal-Fetal Triage Index had a shorter labor and delivery triage evaluation (priority 1, 57 minutes; priority 2, 66 minutes; priority 3, 63 minutes; priority 4, 62 minutes; and priority 5, 83 minutes; P<.001). The rates of admission were higher in the priority 1 and 5 groups (priority 1, 89.3%; priority 2, 41.4%; priority 3, 57.3%; priority 4, 53.3%; and priority 5, 92.6%; P<.001)., Conclusion: Compared with the historical cohort, the duration of labor and delivery triage evaluation was longer in the study cohort. However, in the study cohort, women classified as higher priority according to the Maternal-Fetal Triage Index had a shorter labor and delivery triage evaluation. Our study supports the American College of Obstetricians and Gynecologists' recommendation on the implementation and utilization of labor and delivery triage tools such as the Maternal-Fetal Triage Index., (Copyright © 2021 Elsevier Inc.

Objective: The study aimed to examine the incidence of hypertensive disorders of pregnancy in women diagnosed with SARS-CoV-2 (severe acute respiratory syndrome coronavirus 2, also known as COVID-19)., Study Design: This was a retrospective cohort study of all women who delivered at MedStar Washington Hospital Center in Washington, DC from April 8, 2020 to July 31, 2020. Starting April 8, 2020, universal testing for COVID-19 infection was initiated for all women admitted to labor and delivery. Women who declined universal testing were excluded. Hypertensive disorders of pregnancy were diagnosed based on American College of Obstetricians and Gynecologists Task Force definitions.1 Maternal demographics, clinical characteristics, and labor and delivery outcomes were examined. Neonatal outcomes were also collected. Laboratory values from admission were evaluated. Our primary outcome was the incidence of hypertensive disorders of pregnancy among women who tested positive for COVID-19. The incidence of hypertensive disorders of pregnancy was compared between women who tested positive for COVID-19 and women who tested negative., Results: Of the 1,008 women included in the analysis, 73 (7.2%) women tested positive for COVID-19, of which 12 (16.4%) were symptomatic at the time of admission. The incidence of hypertensive disorders of pregnancy was 34.2% among women who tested positive for COVID-19 and 22.9% women who tested negative for COVID-19 ( p  = 0.03). After adjusting for race, antenatal aspirin use, chronic hypertension, and body mass index >30, the risk of developing any hypertensive disorder of pregnancy was not statistically significant (odds ratio: 1.58 [0.91-2.76])., Conclusion: After adjusting for potential confounders, the risk of developing a hypertensive disorder of pregnancy in women who tested positive for COVID-19 compared with women who tested negative for COVID-19 was not significantly different., Key Points: · There is an increased incidence of hypertensive disorders in women who test positive for COVID-19.. · Characteristics of pregnant women with COVID-19 are similar to those with hypertensive disorders.. · Liver function tests were similar between pregnant women with COVID-19 and women without COVID-19.., Competing Interests: None declared., (Thieme.

Objective: This study aimed to examine the rates of intraamniotic infection between intrauterine pressure catheter with amnioinfusion and intrauterine pressure catheter alone., Study Design: This was a retrospective cohort study of all women who had an intrauterine pressure catheter placement during labor at a tertiary referral hospital from January 2016 to June 2018. Outcomes were compared between women who had an intrauterine pressure catheter with amnioinfusion and intrauterine pressure catheter placement alone. The primary outcome was the rate of intraamniotic infection. Secondary outcomes included postpartum endometritis, postpartum hemorrhage (blood loss of ≥1,000 mL), quantitative blood loss (mL), and cesarean delivery. Multivariable logistic regression analysis was performed to calculate adjusted odds ratios (aOR) and 95% confidence interval (95% CI), controlling for age, race, body mass index, gestational age, and length of time of rupture of membranes., Results: Of 1,268 women with an intrauterine pressure catheter, 298 (23.5%) also had an amnioinfusion. Women who had amnioinfusion through an intrauterine pressure catheter compared with those who had intrauterine pressure catheter alone had similar rates of intraamniotic infection (5.4 vs. 8.0%, crude p  = 0.12, aOR 0.69; 95% CI 0.39-1.21), as well as secondary outcomes such as postpartum endometritis (3.0 vs. 2.5%, crude p  = 0.61, aOR 1.12; 95% CI 0.49-2.53), postpartum hemorrhage (16.1 vs. 15.8%, crude p  = 0.89, aOR 1.07; 95% CI 0.75-1.54), blood loss (479.5 vs. 500 mL, adjusted p  = 0.89), and cesarean delivery (40.6 vs. 43.1%, crude p  = 0.45, aOR 0.90; 95% CI 0.68-1.19)., Conclusion: Amnioinfusion was not associated with increased odds of intraamniotic infection compared with intrauterine pressure catheter placement alone., Key Points: · Amnioinfusion involves instilling fluid into the amniotic cavity to relieve variable decelerations.. · Amnioinfusion is not associated with increased odds of chorioamnionitis compared to IUPC alone.. · Amnioinfusion is not associated with increased odds of PPH compared to IUPC placement alone.., Competing Interests: None declared., (Thieme.

Objective: Data regarding the use of the negative pressure wound therapy (NPWT) system in extremely obese women (body mass index [BMI] ≥ 50 kg/m 2 ) undergoing cesarean delivery are limited. We sought to examine the rate of wound complications in extremely obese women according to postcesarean dressings (NPWT [PICO, Smith & Nephew, St. Peterburg, FL] versus standard dressings). Study design: This was a retrospective cohort study of all extremely obese women (BMI ≥ 50 kg/m 2 ) at 23 weeks' gestation or greater who underwent cesarean delivery at an academic teaching hospital in Washington, DC, between January 2009 and September 2017. During this period, a PICO Single Use NPWT system was used at our institution. Women who missed a postpartum follow-up were excluded. Since 2014, Medstar Washington Hospital Center recommended the use of a PICO Single Use NPWT system for extremely obese women at the time of delivery. However, the ultimate decision to use the NPWT was made by attending physicians, considering the cost of the device and the risk of wound complication. Our primary outcome was a composite of cellulitis, hematoma/seroma, and wound dehiscence. Coarsened exact matching with k-to-k solution was performed using BMI, rupture of membranes, and labor. Results: Of 179 extremely obese women, 73 (40.8%) and 106 (59.2%) received NPWT and standard dressings, respectively; 61 women who received NPWT were matched to 61 women who received standard dressings. The rates of the primary outcome in the unmatched cohort were similar between women who received NPWT and those who received standard dressings (20.6 versus 16.0%; p  = .44). The rates of primary outcome remained similar between women who received NPWT and those who received standard dressings after matching (18.0 versus 18.0%; p  = 1.00). Conclusion: In extremely obese women undergoing cesarean delivery, prophylactic PICO NPWT was not associated with a decreased risk of the primary outcome compared with standard dressings. A large prospective randomized controlled trial would be useful to answer if NPWT is beneficial for extremely obese women.

Purpose: To measure the stiffness of the placenta in healthy and preeclamptic patients in the second and third trimesters of pregnancy using ultrasound shear-wave elastography (SWE). We also aimed to evaluate the effect of age, gestational age, gravidity, parity and body mass index (BMI) on placental stiffness and a possible correlation of stiffness with perinatal outcomes., Methods: In a case-control study, we recruited a total of 47 singleton pregnancies in the second and third trimesters of which 24 were healthy and 23 were diagnosed with preeclampsia. In vivo placental stiffness was measured once at the time of recruitment for each patient. Pregnancies with posterior placentas, multiple gestation, gestational hypertension, chronic hypertension, diabetes, autoimmune disease, fetal growth restriction and congenital anomalies were excluded., Results: The mean placental stiffness was significantly higher in preeclamptic pregnancies compared to controls in the third trimester (difference of means = 16.8; 95% CI (9.0, 24.5); P < 0.001). There were no significant differences in placental stiffness between the two groups in the second trimester or between the severe preeclampsia and preeclampsia without severe features groups (difference of means = 9.86; 95% CI (-5.95, 25.7); P ≥ 0.05). Peripheral regions of the placenta were significantly stiffer than central regions in the preeclamptic group (difference of means = 10.67; 95% CI (0.07, 21.27); P < 0.05), which was not observed in the control group (difference of means = 0.55; 95% CI (- 5.25, 6.35); P > 0.05). We did not identify a correlation of placental stiffness with gestational age, maternal age, gravidity or parity. However, there was a statistically significant correlation with BMI (P < 0.05). In addition, pregnancies with higher placental stiffness during the 2nd and 3rd trimesters had significantly reduced birth weight (2890 ± 176 vs. 2420 ± 219 g) and earlier GA (37.8 ± 0.84 vs. 34.3 ± 0.98 weeks) at delivery (P < 0.05)., Conclusion: Compared to healthy pregnancies, placentas of preeclamptic pregnancies are stiffer and more heterogeneous. Placental stiffness is not affected by gestational age or the severity of preeclampsia but there is a correlation with higher BMI and poor perinatal outcomes.

Objective: To evaluate the effectiveness and safety of an intrauterine vacuum-induced hemorrhage-control device for postpartum hemorrhage treatment., Methods: A multicenter, prospective, single-arm treatment study of a novel intrauterine device that uses low-level vacuum to induce uterine myometrial contraction to achieve control of abnormal postpartum uterine bleeding and postpartum hemorrhage was undertaken at 12 centers in the United States. The primary effectiveness endpoint was the proportion of participants in whom use of the intrauterine vacuum-induced hemorrhage-control device controlled abnormal bleeding without requiring escalating interventions. The primary safety endpoint was the incidence, severity, and seriousness of device-related adverse events. Secondary outcomes included time to bleeding control, rate of transfusion, and device usability scored by each investigator using the device., Results: Of 107 participants enrolled with primary postpartum hemorrhage or abnormal postpartum uterine bleeding, 106 received any study treatment with the device connected to vacuum, and successful treatment was observed in 94% (100/106, 95% CI 88-98%) of these participants. In those 100 participants, definitive control of abnormal bleeding was reported in a median of 3 minutes (interquartile range 2.0-5.0) after connection to vacuum. Eight adverse events deemed possibly related to the device or procedure were reported, all of which were outlined as risks in the study and all of which resolved with treatment without serious clinical sequelae. Transfusion of 1-3 units of red blood cells was required in 35 participants, and five participants required 4 or more units of red blood cells. The majority of investigators reported the intrauterine vacuum-induced hemorrhage-control device as easy to use (98%) and would recommend it (97%)., Conclusion: Intrauterine vacuum-induced hemorrhage control may provide a new rapid and effective treatment option for abnormal postpartum uterine bleeding or postpartum hemorrhage, with the potential to prevent severe maternal morbidity and mortality., Funding Source: Alydia Health, Inc., Clinical Trial Registration: ClinicalTrials.gov, NCT02883673.

Introduction: High utilization of antimicrobial agent (AMA) and inappropriate usage in an intensive care unit (ICU) intensifies resistant organism, morbidity, mortality, and treatment cost. Prescription audit and active feedback are a proven method to check the irrational prescription. To analyze and compare the utilization of drugs, the World Health Organization (WHO) proposed daily defined dose (DDD)/100 patient days and days of therapy (DOT)/100 patient days to measure utilization of AMAs. Data of AMAs utilization are required for planning an antibiotic policy and for follow-up of intervention strategies., Materials and Methods: A prospective observational study was conducted for 1 year from July 2018 to June 2019 and the data obtained from ICU of a tertiary care hospital. The demographic data, the disease data, and the utilization of different classes of AMAs [WHO-Anatomical Therapeutic Chemical (ATC) classification] as well as their cost were recorded. Total number of patient days, DDD, DDD/100 patient days, and DOT/100 patient days were calculated as proposed by the WHO. Statistical analysis was performed using statistical software SPSS version 25.0. The descriptive analysis was performed using summary statistics median [interquartile range (IQR)]., Results: A total 939 patients were included, out of them 332 (35.4%) were female. The median age of the total patients was 58 (45-70). The median length of stay in ICU was 3 days. Mortality rate during our study period was 38.6%. The highly utilized AMAs in our study was ceftriaxone (36.95 DDD/100 patient days) followed by piperacillin/tazobactam (31.57), meropenem (26.4), doxycycline (21.53), and polymyxin B (21.38). The association between APACHE II and SOFA score with use of restricted antibiotics found to be statistical significant ( p value 0.018 and 0.000, respectively). The cost of antibiotics per patient and patient days were $449.97 and $93.77, respectively, while median value of total cost was $2,343.26., Conclusion: Ceftriaxone was the highest utilized AMA. The risk of receiving restricted antibiotics intensified with increasing prevalence of multidrug resistance bacteria and associated comorbidities. High treatment cost is responsible for higher utilization of restricted antibiotics in ICU., How to Cite This Article: Patra SK, Mishra SB, Rath A, Samal S, Iqbal SN.

Objective: We sought to determine if fetuses with prenatally diagnosed congenital heart disease (CHD) were more likely to undergo cesarean delivery in the setting of a non-reassuring fetal heart rate tracing (NRFHT) and to determine if those fetuses were more likely to have a fetal acidosis., Study Design: A retrospective cohort study of neonates prenatally diagnosed with CHD from August 2010 to July 2016. The control group consisted of gestational age matched controls without CHD., Results: Each group consisted of 143 patients. The most common reason for cesarean delivery was a NRFHT (control 31% vs CHD 35%, p = 0.67). Fetal acidosis was a rare outcome occurring in only five controls (3.5%) and 11 cases (7.7%) (p = 0.12)., Conclusion: These findings demonstrate that with multidisciplinary care coordination, fetuses with a prenatal diagnosis of CHD have similar cesarean rates, labor and delivery management, and delivery room compromise as healthy fetuses.

The primary objective was to determine if newborns with congenital heart disease (CHD) are at a higher risk for acidosis at delivery as determined by cord blood gas analysis. The secondary objective was to determine whether specific fetal cardiac diagnosis, delivery method, or duration of labor is associated with an increased risk for acidosis. This was a retrospective study of newborns with CHD diagnosed prenatally and comparable patients without a CHD diagnosis. Study participants included 134 CHD-affected newborns and 134 controls. Median UA pH in CHD newborns was 7.22 (CI 7.2-7.4) and in controls it was 7.22 (CI 7.21-7.24), p = 0.91. There was no difference in median UA pH comparing newborns with single-ventricle CHD and two-ventricle CHD [7.23 (CI 7.2-7.26) vs. 7.22 (CI 7.22-7.24), p = 0.77], or newborns with CHD with aortic obstruction and those without aortic obstruction [7.23 (CI 7.21-7.26) vs. 7.22 (CI 7.2-7.24), p = 0.29]. After controlling for delivery method and duration of labor, CHD patients who underwent a spontaneous vaginal delivery were found to have a declining median UA pH as labor progressed. Our results show that newborns with CHD have a normal UA pH at delivery suggesting a compensated circulation in utero. Spontaneous vaginal delivery with a progressively longer duration of labor in CHD newborns was associated with lower UA pH. This suggests that fetuses with CHD may be at risk for hemodynamic instability at birth with a longer duration of labor as a potentially modifiable factor to improve outcome.

Background: This study was conducted to compare the adaptation of resin-based sealants with that of Resin modified glass ionome-based sealants in various tooth fissure morphologies., Methods: It was an in vitro experimental study done at the Dow University and NED University, Karachi, Pakistan. Ten extracted human molars were randomly assigned to two groups, (n=5) each. Fissure sealant material (Resin based sealant or resin modified glass ionomer-based sealant) was applied on the occlusal surface of the tooth according to manufacturer's recommendations. Specimens were thermocycled and then sectioned into three longitudinal parts in the bucco- lingual direction. Specimens were examined using scanning electron microscope for the adaptation of the sealant in the occlusal fissure. Mann-Whitney -U test and Kruskall-Wallis test were applied to compare the adaptability scores of sealant materials in the tooth fissure. Level of significance was kept at 0.05., Results: There were no significant differences in the adaptability scores among U-shaped (p-value=0.35), V-shaped (p-value=0.89), IK-shaped (p-value=0.52), I-shaped (p-value- =0.41) and Y-shaped (p-value=1.00) fissure patterns. Similarly, there were no significant differences observed between the resin-based sealant (p-value=0.95) versus RMGIC based sealant (p-value=0.63) for the adaptability scores in various tooth fissure morphologies., Conclusions: No significant difference was found between resin-based sealants and resin modified glass ionomerbased sealants for the adaptation in various tooth fissure patterns.

Purpose: To determine the performance of third trimester ultrasound in women with suspected fetal macrosomia., Materials and Methods: We performed a retrospective cohort study of fetal ultrasounds from January 2004 to December 2014 with estimated fetal weight (EFW) between 4000 and 5000 g. We determined accuracy of birth weight prediction for ultrasound performed at less than and greater than 38 weeks, accounting for diabetic status and time between ultrasound and delivery., Results: There were 405 ultrasounds evaluated. One hundred and twelve (27.7%) were performed at less than 38 weeks, 293 (72.3%) at greater than 38 weeks, and 91 (22.5%) were performed in diabetics. Sonographic identification of EFW over 4000 g at less than 38 weeks was associated with higher correlation between EFW and birth weight than ultrasound performed after 38 weeks (71.5 versus 259.4 g, p < .024). EFW to birth weight correlation was within 1.7% of birth weight for ultrasound performed less than 38 weeks and within 6.5% of birth weight for ultrasound performed at greater than 38 weeks., Conclusions: Identification of EFW with ultrasound performed less than 38 weeks has greater reliability of predicting fetal macrosomia at birth than measurements performed later in gestation. EFW to birth weight correlation was more accurate than previous reports.

Understanding the principles by which agents interact with both complex environments and each other is a key goal of decision neuroscience. However, most previous studies have used experimental paradigms in which choices are discrete (and few), play is static, and optimal solutions are known. Yet in natural environments, interactions between agents typically involve continuous action spaces, ongoing dynamics, and no known optimal solution. Here, we seek to bridge this divide by using a "penalty shot" task in which pairs of monkeys competed against each other in a competitive, real-time video game. We modeled monkeys' strategies as driven by stochastically evolving goals, onscreen positions that served as set points for a control model that produced observed joystick movements. We fit this goal-based dynamical system model using approximate Bayesian inference methods, using neural networks to parameterize players' goals as a dynamic mixture of Gaussian components. Our model is conceptually simple, constructed of interpretable components, and capable of generating synthetic data that capture the complexity of real player dynamics. We further characterized players' strategies using the number of change points on each trial. We found that this complexity varied more across sessions than within sessions, and that more complex strategies benefited offensive players but not defensive players. Together, our experimental paradigm and model offer a powerful combination of tools for the study of realistic social dynamics in the laboratory setting., Competing Interests: The authors have declared that no competing interests exist.

Objective: To examine the association of a resident-driven quality initiative with cesarean delivery surgical site infections., Methods: This was a quasi-experimental, preintervention and postintervention study of women undergoing cesarean delivery at 23 weeks of gestation or greater between January 2015 and June 2018 at a single tertiary care center. We implemented a resident-driven, evidence-based surgical bundle, excluding women who underwent emergency cesarean or had chorioamnionitis. The bundle included routine prophylactic antibiotics (both cefazolin and azithromycin), chlorhexidine alcohol skin preparation, use of clippers instead of a razor, vaginal cleansing with povidone iodine, placental removal by umbilical cord traction, subcutaneous tissue closure if wound thickness greater than 2 cm, suture skin closure, dressing removal between 24 and 48 hours, and use of postoperative chlorhexidine soap. Our primary outcome was surgical site infections (superficial incisional, deep incisional, and organ or space surgical site infections) occurring up to 6 weeks postpartum. Outcomes were compared between the preimplementation period (January 2015-August 2016) and postimplementation period (December 2016-June 2018). Coarsened Exact Matching with k-to-k solution was performed using age, race-ethnicity, body mass index, rupture of membranes, and labor., Results: In total, 1,624 underwent cesarean delivery in the preimplementation and 1,523 postimplementation periods, respectively; 1,100 women in the postimplementation period were matched to 1,100 women in the preimplementation period. The rate of surgical site infections in the unmatched cohort was significantly lower in the postimplementation period compared to those in the preimplementation period (2.2% [33/1,523] vs 4.5% [73/1,624]; odds ratio [OR] 0.47 [95% CI 0.31-0.71]; P<.001). This decrease in the rate of surgical site infections remained statistically significant after matching (1.9% [21/1,100] vs 4.1% [45/1,100]; OR 0.46 [0.27-0.77]; P<.001)., Conclusion: After implementation of a resident-driven quality initiative using a surgical bundle, we observed a significant decrease in cesarean surgical site infections.

Background: The optimal route of delivery in early-onset preeclampsia before 34 weeks is debated because many clinicians are reluctant to proceed with induction for perceived high risk of failure., Objective: Our objective was to investigate labor induction success rates and compare maternal and neonatal outcomes by intended mode of delivery in women with early preterm preeclampsia., Study Design: We identified 914 singleton pregnancies with preeclampsia in the Consortium on Safe Labor study for analysis who delivered between 24 0/7 and 33 6/7 weeks. We excluded fetal anomalies, antepartum stillbirth, or spontaneous preterm labor. Maternal and neonatal outcomes were compared between women undergoing induction of labor (n = 460) and planned cesarean delivery (n = 454) and women with successful induction of labor (n = 214) and unsuccessful induction of labor (n = 246). We calculated relative risks and 95% confidence intervals to determine outcomes by Poisson regression model with propensity score adjustment. The calculation of propensity scores considered covariates such as maternal age, gestational age, parity, body mass index, tobacco use, diabetes mellitus, chronic hypertension, hospital type and site, birthweight, history of cesarean delivery, malpresentation/breech, simplified Bishop score, insurance, marital status, and steroid use., Results: Among the 460 women with induction (50%), 47% of deliveries were vaginal. By gestational age, 24 to 27 6/7, 28 to 31 6/7, and 32 to 33 6/7, the induction of labor success rates were 38% (12 of 32), 39% (70 of 180), and 54% (132 of 248), respectively. Induction of labor compared with planned cesarean delivery was less likely to be associated with placental abruption (adjusted relative risk, 0.33; 95% confidence interval, 0.16-0.67), wound infection or separation (adjusted relative risk, 0.23; 95% confidence interval, 0.06-0.85), and neonatal asphyxia (0.12; 95% confidence interval, 0.02-0.78). Women with vaginal delivery compared with those with failed induction of labor had decreased maternal morbidity (adjusted relative risk, 0.27; 95% confidence interval, 0.09-0.82) and no difference in neonatal outcomes., Conclusion: About half of women with preterm preeclampsia who attempted an induction had a successful vaginal delivery. The rate of successful vaginal delivery increases with gestational age. Successful induction has the benefit of preventing maternal and fetal comorbidities associated with previous cesarean deliveries in subsequent pregnancies. While overall rates of a composite of serious maternal and neonatal morbidity/mortality did not differ between induction of labor and planned cesarean delivery groups, women with failed induction of labor had increased maternal morbidity highlighting the complex route of delivery counseling required in this high-risk population of women., (Copyright © 2018.

We report the first draft genome sequence of a Vibrio parahaemolyticus strain ( Vp AHPND ), which causes acute hepatopancreatic necrosis disease (AHPND) in Penaeus monodon. The strain has a pVA1-like plasmid carrying pirA vp and pirB vp genes. Whole-genome comparisons revealed >98% similarity to Vp AHPND isolates from Thailand, Mexico, and Vietnam.

A 78-year-old man with remote type-A dissection presented with acute-onset dyspnea. Twenty-two years prior, treatment for his aortic disease required replacement of ascending and arch aneurysms with a polyester graft (Dacron) using the graft inclusion technique. He presented currently in cardiogenic shock. Echocardiography demonstrated new severe hypokinesis of all apical segments. Left-heart catheterization revealed a 120 mm Hg intragraft gradient. Computed tomography arteriography was unrevealing, but intraaortic ultrasound demonstrated critical intragraft stenosis. A balloon expandable stent (Palmaz stent, Cordis, Milpitas, CA) was deployed in the stenotic region with gradient resolution. The patient later underwent aortic root replacement and ascending aneurysm repair (Bio-Bentall technique) and is doing well at 24 months., (Copyright © 2018 The Society of Thoracic Surgeons.

Objective: The relationship between placental and fetal brain growth is poorly understood and difficult to assess. The objective of this study was to interrogate placental and fetal brain growth in healthy pregnancies and those complicated by fetal growth restriction (FGR)., Study Design: In a prospective, observational study, pregnant women with normal pregnancies or pregnancies complicated by FGR underwent fetal magnetic resonance imaging (MRI). Placental, global and regional brain volumes were calculated., Results: A total of 114 women (79 controls and 35 FGR) underwent MRI (median gestational age (GA) 30 weeks, range 18 to 39). All measured volumes increased exponentially with advancing GA. Placental, total brain, cerebral and cerebellar volumes were smaller in FGR compared with controls (P<0.05). Increasing placental volume was associated with increasing cerebral and cerebellar volumes (P<0.05)., Conclusion: Quantitative fetal MRI can accurately detect decreased placental and brain volumes in pregnancies with FGR and may provide insight into the timing and mechanisms of brain injury in FGR.

Background: Congenital fetal cardiac anomalies compromise the most common group of fetal structural anomalies. Several previous reports analyzed all types of fetal cardiac anomalies together without individualized neonatal morbidity outcomes based on cardiac defect. Mode of delivery in cases of fetal cardiac anomalies varies greatly as optimal mode of delivery in these complex cases is unknown., Objective: We sought to determine rates of neonatal outcomes for fetal cardiac anomalies and examine the role of attempted route of delivery on neonatal morbidity., Study Design: Gravidas with fetal cardiac anomalies and delivery >34 weeks, excluding stillbirths and aneuploidies (n = 2166 neonates, n = 2701 cardiac anomalies), were analyzed from the Consortium on Safe Labor, a retrospective cohort study of electronic medical records. Cardiac anomalies were determined using International Classification of Diseases, Ninth Revision codes and organized based on morphology. Neonates were assigned to each cardiac anomaly classification based on the most severe cardiac defect present. Neonatal outcomes were determined for each fetal cardiac anomaly. Composite neonatal morbidity (serious respiratory morbidity, sepsis, birth trauma, hypoxic ischemic encephalopathy, and neonatal death) was compared between attempted vaginal delivery and planned cesarean delivery for prenatal and postnatal diagnosis. We used multivariate logistic regression to calculate adjusted odds ratio for composite neonatal morbidity controlling for race, parity, body mass index, insurance, gestational age, maternal disease, single or multiple anomalies, and maternal drug use., Results: Most cardiac anomalies were diagnosed postnatally except hypoplastic left heart syndrome, which had a higher prenatal than postnatal detection rate. Neonatal death occurred in 8.4% of 107 neonates with conotruncal defects. Serious respiratory morbidity occurred in 54.2% of 83 neonates with left ventricular outflow tract defects. Overall, 76.3% of pregnancies with fetal cardiac anomalies underwent attempted vaginal delivery. Among patients who underwent attempted vaginal delivery, 66.1% had a successful vaginal delivery. Women with a fetal cardiac anomaly diagnosed prenatally were more likely to have a planned cesarean delivery than women with a postnatal diagnosis (31.7 vs 22.8%; P < .001). Planned cesarean delivery compared to attempted vaginal delivery was not associated with decreased composite neonatal morbidity for all prenatally diagnosed (adjusted odds ratio, 1.67; 95% confidence interval, 0.85-3.30) or postnatally diagnosed (adjusted odds ratio, 0.99; 95% confidence interval, 0.77-1.27) cardiac anomalies., Conclusion: Most fetal cardiac anomalies were diagnosed postnatally and associated with increased rates of neonatal morbidity. Planned cesarean delivery for prenatally diagnosed cardiac anomalies was not associated with less neonatal morbidity., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Background: The prevalence of morbid obesity (body mass index ≥40 kg/m 2 ) in women aged 20-39 years was 7.5% in 2009 through 2010. Morbid obesity is associated with an increased risk of stillbirth compared with normal body mass index, especially >39 weeks' gestation. The data regarding increased risk of cesarean delivery associated with nonmedically indicated induction of labor compared to expectant management in morbidly obese women are limited., Objective: We sought to compare the cesarean delivery rate of nonmedically indicated induction of labor with expectant management in morbidly obese women without other comorbidity., Study Design: This was a retrospective cohort study from the Consortium on Safe Labor of morbidly obese women with singleton, cephalic gestations without previous cesarean, chronic hypertension, or gestational or pregestational diabetes between 37 0/7 and 41 6/7 weeks' gestation. We examined maternal outcomes including cesarean delivery, operative delivery, third- or fourth-degree laceration, postpartum hemorrhage, and composite maternal outcome (any of: transfusion, intensive care unit admission, venous thromboembolism). We also examined neonatal outcomes including shoulder dystocia, macrosomia (>4000 g), neonatal intensive care unit admission, and composite neonatal outcome (5-min Apgar score <5, stillbirth, neonatal death, or asphyxia or hypoxic-ischemic encephalopathy). Adjusted odds ratios with 95% confidence intervals were calculated, controlling for maternal characteristics, hospital type, and simplified Bishop score. Analyses were conducted at early and full term (37 0/7 to 38 6/7 and 39 0/7 to 40 6/7 weeks' gestation, respectively). Women who delivered between 41 0/7 and 41 6/7 weeks' gestation were included as expectant management group., Results: Of 1894 nulliparous and 2455 multiparous morbidly obese women, 429 (22.7%) and 791 (32.2%) had nonmedically indicated induction, respectively. In nulliparas, nonmedically indicated induction was not associated with increased risks of cesarean delivery and was associated with decreased risks of macrosomia (2.2% vs 11.0%; adjusted odds ratio, 0.24; 95% confidence interval, 0.05-0.70) at early term and decreased neonatal intensive care unit admission (5.1% vs 8.9%; adjusted odds ratio, 0.59; 95% confidence interval, 0.33-0.98) at full term compared with expectant management. In multiparas, nonmedically indicated induction compared with expectant management was associated with a decreased risk of macrosomia at early term (4.2% vs 14.3%; adjusted odds ratio, 0.30; 95% confidence interval, 0.13-0.60), cesarean delivery at full term (5.4% vs 7.9%; adjusted odds ratio, 0.64; 95% confidence interval, 0.41-0.98), and composite neonatal outcome (0% vs 0.6%; adjusted odds ratio, 0.10; 95% confidence interval, <.01-0.89) at full term., Conclusion: In morbidly obese women without other comorbidity, nonmedically indicated induction was not associated with an increased risk of cesarean delivery., (Copyright © 2017 Elsevier Inc.

Invasive coronary angiography is routinely performed during the initial evaluation of patients with suspected cardiomyopathy with reduced left ventricular function. Clinical and electrocardiographic (ECG) data may accurately predict ischemic cardiomyopathy (IC). Medical records of adults referred for coronary angiography for evaluation of left ventricular ejection fraction ≤40% from 2010 to 2014 were retrospectively reviewed. Patients with myocardial infarction (MI), previous coronary revascularization, cardiac surgery, or left-sided valvular disease were excluded. IC was defined as ≥70% diameter stenosis of the left main, proximal left anterior descending, or involvement of ≥2 epicardial coronary arteries. A risk model was developed from logistic regression coefficients, with a dichotomous cut-point based on the maximal Youden's index from the receiver-operating characteristic curve. A total of 273 patients met study inclusion criteria. Mean age was 56.8 ± 11.6 and 68.1% were men. IC was identified in 41 patients (15%). Patients with IC were more likely to have ECG evidence of Q-wave MI (34% vs 13%, p <0.001) and less likely to have left bundle branch block (2% vs 15%, p = 0.03) than non-IC. A model including age, hypertension, diabetes mellitus, tobacco use, ECG evidence of ST or T-wave abnormalities concerning for ischemia, and previous Q-wave MI, yielded a 95% negative predictive value for IC. In conclusion, at an urban referral hospital, the prevalence of IC was low. Left bundle branch block on electrocardiography was rarely associated with IC. A risk score incorporating clinical and ECG abnormalities identified patients at a low likelihood for IC., (Copyright © 2017 Elsevier Inc. All rights reserved.)

Purpose: To determine if diabetic gravidas enrolled in Centering® group care have improved glycemic control compared to those attending standard prenatal care. To compare compliance and patient satisfaction between the groups., Materials and Methods: We conducted a prospective cohort study of diabetics enrolled in centering group care from October 2013 to December 2015. Glycemic control, compliance and patient satisfaction (five-point Likert scale) were evaluated. Student's t-test, Chi-Square and mixed effects model were used to compare outcomes., Results: We compared 20 patients in centering to 28 standard prenatal care controls. Mean fasting blood sugar was lower with centering group care (91.0 versus 105.5 mg/dL, p =0.017). There was no difference in change in fasting blood sugar over time between the two groups (p = 0.458). The percentage of time patients brought their blood glucose logs did not differ between the centering group and standard prenatal care (70.7 versus 73.9%, p = 0.973). Women in centering group care had better patient satisfaction scores for "ability to be seen by a physician" (5 versus 4, p = 0.041) and "time in waiting room" (5 versus 4, p =0.001)., Conclusion: Fasting blood sugar was lower for patients in centering group care. Change in blood sugar over time did not differ between groups. Diabetic gravidas enrolled in centering group care report improved patient satisfaction.

Introduction: Data on the correlation among Hemoglobin A1c (HbA1c), placental pathology, and perinatal outcome in the pregestational diabetic population is severely lacking. We believe that this knowledge will enhance the management of pregnancies complicated by pregestational diabetes. We hypothesize that placental pathology correlates with glycemic control at an early gestational age., Methods: This is a retrospective cohort study conducted from 2003 to 2011 at a large tertiary care center. Women included had a singleton gestation, preexisting diabetes mellitus, and information about delivery and placental pathology available for review. Placental pathology and perinatal outcomes were compared across three groups of patients with differing HbA1c levels (<6.5%, 6.5-8.4%, and ≥8.5%)., Results: 293 placentas were examined. HbA1c was measured at a mean of 9.5week gestation. Median HbA1c was 7.5%, interquartile range 6.5%-8.9%. 23% of the cohort had HbA1c <6.5%, 41.9% between 6.5% and 8.4%, and 34.8% > 8.5%. BMI varied significantly by group (35.4 vs. 34.4 vs. 32.0 respectively, P = 0.04). Individual placental lesions did not vary with HbA1c levels. The incidence of acute chorioamnionitis differed significantly in the type 1 population and "distal villous hypoplasia" varied in the type 2 population., Discussion: The results show that HbA1c values in early pregnancy are poor predictors of future placental pathologies. As a result, HbA1c values obtained during early gestation (which reflect the level of glycemic control over an extended period of time) do not correlate with any particular placental pathology, despite reflecting the potential for placental insults secondary to pre-gestational diabetes., (Copyright © 2017.

Background: Data on complications associated with classic cesarean delivery are conflicting. In extremely preterm cesarean delivery (22 0/7-27 6/7 weeks' gestation), the lower uterine segment is thicker. It is plausible that the rates of maternal complications may not differ between classic and low transverse cesarean., Objective: We sought to compare maternal outcomes associated with classic versus low transverse cesarean after stratifying by gestation (23 0/7-27 6/7 and 28 0/7-31 6/7 weeks' gestation)., Study Design: We conducted a multihospital retrospective cohort study of women undergoing cesarean delivery at 23 0/7 to 31 6/7 weeks' gestation from 2005 through 2014. Composite maternal outcome (postpartum hemorrhage, transfusion, endometritis, sepsis, wound infection, deep venous thrombosis/pulmonary embolism, hysterectomy, respiratory complications, and intensive care unit admission) was compared between classic and low transverse cesarean. Outcomes were calculated using multivariable logistic regression models yielding adjusted odds ratios with 95% confidence intervals and adjusted P values controlling for maternal characteristics, emergency cesarean delivery, and comorbidities. Analyses were stratified by gestational age categories (23 0/7-27 6/7 and 28 0/7-31 6/7 weeks' gestation)., Results: Of 902 women, 221 (64%) and 91 (16%) underwent classic cesarean between 23 0/7 and 27 6/7 and between 28 0/7 and 31 6/7 weeks' gestation, respectively. There was no increase in maternal complications for classic cesarean versus low transverse cesarean between 23 0/7 and 27 6/7 weeks' gestation. However, between 28 0/7 and 31 6/7 weeks' gestation, classic cesarean was associated with increased risks of the composite maternal outcome (adjusted odds ratio, 1.95; 95% confidence interval, 1.10-3.45), transfusion (adjusted odds ratio, 2.42; 95% confidence interval, 1.06-5.52), endometritis (adjusted odds ratio, 3.23; 95% confidence interval, 1.02-10.21), and intensive care unit admission (adjusted odds ratio, 5.05; 95% confidence interval, 1.37-18.52) compared to low transverse cesarean., Conclusion: Classic cesarean delivery compared with low transverse was associated with higher maternal complication rates between 28 0/7 and 31 6/7 weeks, but not between 23 0/7 and 27 6/7 weeks' gestation., (Copyright © 2016 Elsevier Inc.

Objectives: To estimate the incidence and risk of complications associated with a fetal scalp electrode and to determine whether its application in the setting of operative vaginal delivery was associated with increased neonatal morbidity., Design: Retrospective cohort study., Setting: Twelve clinical centers with 19 hospitals across nine American Congress of Obstetricians and Gynecologists US districts., Population: Women in the USA., Methods: We evaluated 171 698 women with singleton deliveries ≥ 23 weeks of gestation in a secondary analysis of the Consortium on Safe Labor study between 2002 and 2008, after excluding conditions that precluded fetal scalp electrode application such as prelabour caesarean delivery. Secondary analysis limited to operative vaginal deliveries ≥ 34 weeks of gestation was also performed., Main Outcome Measures: Incidences and adjusted odds ratios with 95% confidence intervals of neonatal complications were calculated, controlling for maternal characteristics, delivery mode and pregnancy complications., Results: Fetal scalp electrode was used in 37 492 (22%) of deliveries. In non-operative vaginal delivery, fetal scalp electrode was associated with increased risk of injury to scalp due to birth trauma (1.2% versus 0.9%; adjusted odds ratios 1.62; 95% confidence intervals 1.41-1.86) and cephalohaematoma (1.0% versus 0.9%; adjusted odds ratios 1.57; 95% confidence intervals 1.36-1.83). Neonatal complications were not significantly different comparing fetal scalp electrode with vacuum-assisted vaginal delivery and vacuum-assisted vaginal delivery alone or comparing fetal scalp electrode with forceps-assisted vaginal delivery and forceps-assisted vaginal delivery alone., Conclusions: We found increased neonatal morbidity with fetal scalp electrode though the absolute risk was very low. It is possible that these findings reflect an underlying indication for its use. Our findings support the use of fetal scalp electrodes when clinically indicated., Tweetable Abstract: Neonatal risks associated with fetal scalp electrode use were low (injury to scalp 1.2% and cephalohaematoma 1.0%)., Competing Interests: of interest: The authors report no conflicts of interest.

Background: Obesity is a known risk factor for cesarean delivery. Limited data are available regarding the reasons for the increased rate of primary cesarean in obese women. It is important to identify the factors leading to an increased risk of cesarean to identify opportunities to reduce the primary cesarean rate., Objective: We evaluated indications for primary cesarean across body mass index (kg/m(2)) classes to identify the factors contributing to the increased rate of cesarean among obese women., Study Design: In the Consortium of Safe Labor study from 2002 through 2008, we calculated indications for primary cesarean including failure to progress or cephalopelvic disproportion, nonreassuring fetal heart tracing, malpresentation, elective, hypertensive disease, multiple gestation, placenta previa or vasa previa, failed induction, HIV or active herpes simplex virus, history of uterine scar, fetal indication, placental abruption, chorioamnionitis, macrosomia, and failed operative delivery. For women with primary cesarean for failure to progress or cephalopelvic disproportion, dilation at the last recorded cervical examination was evaluated. Women were categorized according to body mass index on admission: normal weight (18.5-24.9), overweight (25.0-29.9), and obese classes I (30.0-34.9), II (35.0-39.9), and III (≥40). Cochran-Armitage trend test and χ(2) tests were performed., Results: Of 66,502 nulliparous and 76,961 multiparous women in the study population, 19,431 nulliparous (29.2%) and 7329 multiparous (9.5%) women underwent primary cesarean. Regardless of parity, malpresentation, failure to progress or cephalopelvic disproportion, and nonreassuring fetal heart tracing were the common indications for primary cesarean. Regardless of parity, the rates of primary cesarean for failure to progress or cephalopelvic disproportion increased with increasing body mass index (normal weight, overweight, and classes I, II, and III obesity in nulliparous women: 33.2%, 41.6%, 46.4%, 47.4%, and 48.9% [P < .01] and multiparous women: 14.5%, 20.3%, 22.8%, 27.2%, and 25.3% [P < .01]), whereas the rates for malpresentation decreased (normal weight, overweight, and classes I, II, and III obesity in nulliparous women: 23.7%, 17.2%, 14.6%, 12.0%, and 9.1% [P < .01] and multiparous women: 35.6%, 30.6%, 26.5%, 24.3%, and 22.9% [P < .01]). Rates of primary cesarean for nonreassuring fetal heart tracing were not statistically different for nulliparous (P > .05) or multiparous (P > .05) women. Among nulliparous women who had a primary cesarean for failure to progress or cephalopelvic disproportion, rates of cesarean prior to active labor (6 cm) increased as body mass index increased, accounting for 39.3% of women with class I, 47.1% of women with class II, and 56.8% of women with class III obesity compared to 35.2% for normal-weight women (P < .01)., Conclusion: Similar to normal-weight women, the indication of cesarean for failure to progress or cephalopelvic disproportion was the major factor contributing to the increase in primary cesarean in obese women, but was even more prevalent with increasing obesity class. The rates of intrapartum primary cesarean prior to achieving active labor increased with increasing obesity class in nulliparous women., Competing Interests: The authors report no conflicts of interest., (Copyright © 2016 Elsevier Inc.

Objective: To compare maternal and neonatal outcomes based on length of the latent phase during induction with rupture of membranes before 6 cm dilation., Methods: This is a retrospective cohort study using data from the Consortium of Safe Labor study, including 9,763 nulliparous and 8,379 multiparous women with singleton, term pregnancies undergoing induction at 2 cm dilation or less with rupture of membranes before 6 cm dilation after which the latent phase ended. Outcomes were evaluated according to duration of oxytocin and rupture of membranes., Results: At time points from 6 to 18 hours of oxytocin and rupture of membranes, the rates of nulliparous women remaining in the latent phase declined (35.9-1.4%) and the rates of vaginal delivery for those remaining in the latent phase at these time periods decreased (54.1-29.9%) Nulliparous women remaining in the latent phase for 12 hours compared with women who had exited the latent phase had significantly increased rates of chorioamnionitis (12.1% compared with 4.1%) and endometritis (3.6% compared with 1.3%) and increased rates of neonatal intensive care unit admission (8.7% compared with 6.3%). Similar patterns were present for multiparous women at 15 hours., Conclusion: Based on when neonatal morbidity increased, in an otherwise uncomplicated induction of labor with rupture of membranes, a latent phase after initiation of oxytocin of at least 12 hours for nulliparous women and 15 hours in multiparous women is a reasonable criterion for diagnosing a failed induction.

Objective: To evaluate maternal and neonatal outcomes by attempted mode of operative delivery from a low station in the second stage of labor., Methods: Retrospective study of 2,518 women carrying singleton fetuses at 37 weeks of gestation or greater who underwent attempted forceps-assisted delivery, attempted vacuum-assisted vaginal delivery, or cesarean delivery from a low station in the second stage of labor. Primary outcomes were stratified by parity and included a maternal adverse outcome composite (postpartum hemorrhage, transfusion, endometritis, peripartum hysterectomy, or intensive care unit admission) and a neonatal adverse outcome composite (5-minute Apgar score less than 4, respiratory morbidity, neonatal intensive care unit admission, shoulder dystocia, birth trauma, or sepsis)., Results: In nulliparous patients, the maternal adverse composite was not significantly different between women who underwent attempted forceps (12.1% compared with 10.8%, adjusted odds ratio [OR] 0.77, 95% confidence interval [CI] 0.40-1.34) or vacuum (8.3% compared with 10.8%, adjusted OR 0.68, 95% CI 0.40-1.16) delivery compared with cesarean delivery. Among parous women, the maternal adverse composite was not significantly different with attempted forceps (10.7% compared with 12.5%, adjusted OR 0.40, 95% CI 0.09-1.71) or vacuum (11.3% compared with 12.5%, adjusted OR 0.44, 95% CI 0.11-1.72) compared with cesarean delivery. Compared with neonates delivered by cesarean, the neonatal adverse composite was significantly lower among neonates born to nulliparous women who underwent attempted forceps (9.4% compared with 16.7%, adjusted OR 0.44, 95% CI 0.27-0.72) but not among those who underwent vacuum delivery (11.9% compared with 16.7%, adjusted OR 0.68, 95% CI 0.44-1.04). Among parous women, the neonatal adverse composite was not significantly different after attempted forceps (4.1% compared with 12.5%, adjusted OR 0.28, 95% CI 0.06-1.35) or vacuum (12.5% compared with 12.5%, adjusted OR 1.03, 95% CI 0.28-3.87) compared with cesarean delivery., Conclusion: A trial of forceps delivery from a low station compared with cesarean delivery was associated with decreased neonatal morbidity among neonates born to nulliparous women., Level of Evidence: II.

The aim of this study was to determine the diagnostic value of cardiac magnetic resonance (CMR) imaging with late gadolinium enhancement (LGE), cine imaging, and resting first-pass perfusion (FPP) in the evaluation for ischemic (IC) versus nonischemic (NIC) cardiomyopathy in new-onset heart failure with reduced (≤40%) left ventricular ejection fraction (HFrEF). A retrospective chart review analysis identified 83 patients from January 2009 to June 2012 referred for CMR imaging evaluation for new-onset HFrEF with coronary angiography performed within 6 months of CMR. The diagnosis of IC was established using Felker criteria on coronary angiography. CMR sequences were evaluated for the presence of patterns suggestive of severe underlying coronary artery disease as the cause of HFrEF (subendocardial and/or transmural LGE, regional wall motion abnormality on cine, regional hypoperfusion defect on resting FPP). Discriminative power was assessed using receiver operator characteristics curve analysis. Coronary angiography identified 36 patients (43%) with IC. Presence of subendocardial and/or transmural LGE alone demonstrated good discriminative power (C-statistic 0.85, 95% confidence interval 0.76 to 0.94) for the diagnosis of IC. The presence of an ischemic pattern on both LGE and cine sequences resulted in a specificity of 87% for the diagnosis of IC, whereas the absence of an ischemic pattern on both LGE and cine sequences resulted in a specificity of 94% for the diagnosis of NIC. Addition of resting FPP on a subset of patients did not improve diagnostic values. In conclusion, CMR has potential value in the diagnostic evaluation of IC versus NIC., (Published by Elsevier Inc.)

Arrhythmias in pregnancy are becoming more common given more available and effective medical, ablation and device treatment options. Several changes associated with pregnancy, increased blood volume, cardiac output, and heart rate secondary to an increased sympathetic state, facilitate more frequent occurrences of arrhythmias throughout the pregnancy and during labor and delivery. We present a case of successful pregnancy in a teenage female with a previous diagnosis of CPVT, followed by a review of the literature.

Objective: We sought to determine predictors of adverse neonatal outcomes in women with intrahepatic cholestasis of pregnancy (ICP)., Study Design: This study was a multicenter retrospective cohort study of all women diagnosed with ICP across 5 hospital facilities from January 2009 through December 2014. Obstetric and neonatal complications were evaluated according to total bile acid (TBA) level. Multivariable logistic regression models were developed to evaluate predictors of composite neonatal outcome (neonatal intensive care unit admission, hypoglycemia, hyperbilirubinemia, respiratory distress syndrome, transient tachypnea of the newborn, mechanical ventilation use, oxygen by nasal cannula, pneumonia, and stillbirth). Predictors including TBA level, hepatic transaminase level, gestational age at diagnosis, underlying liver disease, and use of ursodeoxycholic acid were evaluated., Results: Of 233 women with ICP, 152 women had TBA levels 10-39.9 μmol/L, 55 had TBA 40-99.9 μmol/L, and 26 had TBA ≥100 μmol/L. There was no difference in maternal age, ethnicity, or prepregnancy body mass index according to TBA level. Increasing TBA level was associated with higher hepatic transaminase and total bilirubin level (P < .05). TBA levels ≥100 μmol/L were associated with increased risk of stillbirth (P < .01). Increasing TBA level was also associated with earlier gestational age at diagnosis (P < .01) and ursodeoxycholic acid use (P = .02). After adjusting for confounders, no predictors were associated with composite neonatal morbidity. TBA 40-99.9 μmol/L and TBA ≥100 μmol/L were associated with increased risk of meconium-stained amniotic fluid (adjusted odds ratio, 3.55; 95% confidence interval, 1.45-8.68 and adjusted odds ratio, 4.55; 95% confidence interval, 1.47-14.08, respectively)., Conclusion: In women with ICP, TBA level ≥100 μmol/L was associated with increased risk of stillbirth. TBA ≥40 μmol/L was associated with increased risk of meconium-stained amniotic fluid., Competing Interests: The authors report no conflict of interest., (Copyright © 2015 Elsevier Inc.

Despite increasing use of the transradial approach (TRA) for coronary angiography, TRA failure and subsequent access site crossover remain a barrier to TRA adoption. The aim of this study was to elucidate patient and procedural characteristics associated with TRA to transfemoral approach (TFA) crossover and examine TRA to TFA crossover by operator experience over time. This retrospective analysis identified 1,600 patients who underwent coronary angiography with possible percutaneous coronary intervention through TRA by operators with varied TRA experience in an urban tertiary care center from October 2010 to August 2013. Univariate and multivariable logistic regression were used to identify independent predictors of access site crossover, from TRA to TFA, and strength of association is presented as odds ratio (OR, 95% confidence interval [CI]). Access site crossover was noted in 166 patients (10.4%). Multivariable predictors of access site crossover included age >75 years (OR 1.90, 95% CI 1.23 to 2.91, p = 0.004) and operator experience (OR 2.98, 95% CI 1.96 to 4.52, p <0.0001). Less experienced operators (≤5 years TRA experience) had a decrease in access site crossover over time (quartile 1: 8.9%, quartile 2: 18.8%, quartile 3: 16.4%, and quartile 4: 8.6%, p <0.001), which paralleled an increase in the proportion of procedures using initial TRA over time (quartile 1: 38.0%, quartile 2: 53.7%, quartile 3: 54.8%, and quartile 4: 70.3%, p <0.001). Experienced operators (>5 years TRA experience) had no significant change in proportion of access site crossover over time (quartile 1: 2.8%, quartile 2: 6.4%, quartile 3: 5.6%, quartile 4: 5.8%, p = 0.54). In conclusion, rate of access site crossover in the contemporary era is relatively low and can be mitigated with operator experience., (Published by Elsevier Inc.)

Introduction: This study examined the outcomes of triplet pregnancies selectively reduced to twin pregnancies, compared with non-reduced triplet pregnancies using a standardized approach., Material and Methods: This study is an observational retrospective study of all women who presented to the Fetal Diagnostic Center between 1999-2009, had triplet pregnancies in the first trimester, received prenatal care and delivered at Abington Memorial Hospital. Data analysis was performed with SPPS version 15 for Windows using analysis of variance and Fisher's Exact test., Results: 132 triplet pregnancies were identified. In the reduced group ( n = 30) compared to the non-reduced triplet group ( n = 102) average gestational age of delivery was longer 34.6 weeks versus 31.2 weeks gestation ( P = <0.0005) and days in hospital were less 9.0 versus 26.7 days ( P = .001). There was a significantly lower incidence of gestational diabetes and preterm labor in reduced pregnancies. Rate of loss, defined as delivery less than 24 weeks, were similar [3.3% versus 4.9%]., Discussion: Women electing to reduce a triplet pregnancy to twins have higher gestational ages at delivery, lower rates of gestational diabetes and preterm labor, and spent fewer days in hospital than non-reduced triplet pregnancies.

HELLP syndrome is a collection of symptoms described as hemolysis, elevated liver enzymes and low platelets. HELLP syndrome complicates 0.01-0.6% of pregnancies and can be considered a severe variant of preeclampsia. The occurrence of HELLP syndrome diagnosed before the 20th week of gestation has been most commonly reported in association with antiphospholipid antibody syndrome (APS) or triploid chromosomal anomalies. A 41-year-old primigravida was admitted at 17 weeks and 6 days gestation with hypertension, proteinuria, hemolytic anemia and acute renal injury. She was diagnosed with HELLP syndrome, and subsequently suffered from an intrauterine fetal demise. After delivery, the clinical manifestations of HELLP syndrome resolved within 7 days with the exception of her acute renal failure. Interdisciplinary teams of physicians were able to exclude other imitators of preeclampsia, such as hemolytic uremic syndrome (HUS), thrombotic thrombocytopenic purpura (TTP), APS, lupus and acute fatty liver of pregnancy. This case is difficult to diagnose, given the similar presentation of several microangiopathic hemolytic anemias. The clinical manifestations and laboratory findings of HELLP and its mimicking conditions seem as if they are mirror images of each other. However, the discrete differences in our patient presentation, clinical findings, laboratory results and overall postpartum course leave HELLP syndrome as the most consistent diagnosis. It is imperative to investigate for all possible etiologies as HELLP syndrome at 17 weeks gestation is extremely rare and mimicking conditions may require alternative management strategies.

Objective: To observe the difference in dimension of teeth among adult females with and without malocclusion., Methods: The cross-sectional study was conducted at Dr. Ishrat-ul-Ebad Khan Institute of Oral Health Sciences, Dow University of Health Sciences, Karachi, from April 2011 to April 2013, and used non-probability consecutive sampling. Mesiodistal and buccolingual crown dimensions were measured on study casts by using digital sliding caliper in 2 groups of females. Group 1 had 150 subjects with normal occlusion, while Group 2 had 234 with malocclusion. Independent t test was conducted to evaluate the difference between the dimensions of teeth of the two groups. Statistical analysis was done on SPSS version 16, and p value was considered significant at 0.05., Results: Overall, the difference between the groups showed a greater tooth dimension in the malocclusion group of population compared to the normal group, and the most significant difference was observed in the mesiodistal dimension of maxillary 2nd premolar, which was 0.9 +/- 0.6801mm greater in dimension in the malocclusion group compared to the normal group. The least difference was observed in the buccolingual dimension of the mandibular central incisor where the malocclusion group had only 0.08 +/- 0.5247mm larger mandibular central incisors in the buccolingual dimension compared to the normal group., Conclusion: Mesiodistal and buccolingual crown dimensions were characteristically larger in the malocclusion group.

Background: In a prospective study, we previously identified plaque disruption (PD: plaque rupture or ulceration) in 38% of women with myocardial infarction (MI) without angiographically obstructive coronary artery disease (CAD), using intravascular ultrasound (IVUS). Underlying plaque morphology has not been described in these patients and may provide insight into the mechanisms of MI without obstructive CAD., Methods: Forty-two women with MI and <50% angiographic stenosis underwent IVUS (n = 114 vessels). Analyses were performed by a blinded core laboratory. Sixteen patients had PD (14 ruptures and 5 ulcerations in 18 vessels). Plaque area, % plaque burden, lumen area stenosis, eccentricity, and remodeling index were calculated for disrupted plaques and largest plaque by area in each vessel., Results: Disrupted plaques had lower % plaque burden than the largest plaque in the same vessel (31.9% vs 49.8%, P = .005) and were rarely located at the site of largest plaque (1/19). Disrupted plaques were typically fibrous and were not more eccentric or remodeled than the largest plaque in the same vessel., Conclusions: Plaque disruption was often identifiable on IVUS in women with MI without obstructive CAD. Plaque disruption in this patient population occurred in fibrous or fibrofatty plaques and, contrary to expectations based on prior studies of plaque vulnerability, did not typically occur in eccentric, outwardly remodeled, or soft plaque in these patients. Plaque disruption rarely occurred at the site of the largest plaque in the vessel. These findings suggest that the pathophysiology of PD in women with MI without angiographically obstructive CAD may be different from MI with obstructive disease and requires further investigation., (Copyright © 2014 Mosby, Inc.

Circulating cell free fetal DNA (cffDNA) is an effective screening modality for fetal aneuploidy. We report two cases of false positive results. The first case involves a female, with self-reported Down syndrome. CffDNA returned positive for trisomy 18 leading to a maternal diagnosis of mosaicism chromosome 18 with normal fetal karyotype. The second case involves a patient with an anomalous fetal ultrasound and cffDNA positive for trisomy 13. Amniocentesis demonstrated a chromosome 8p duplication/deletion. False positive cffDNA may arise in clinical scenarios where diagnostic testing is clearly indicated. Practitioners should recognize the limitations of cffDNA.

Background: Paroxysmal supraventricular tachycardia (PSVT) has always been a diagnostic and therapeutic challenge for the cardiologists. There are many modalities to treat the problem. Of the available pharmacological treatment, the role of verapamil and adenosine is under debate. This study was carried out to detect and compare the efficacy of both drugs. The objective of this study was to compare the efficacy of intravenous adenosine and verapamil in termination of PSVT., Methods: This experimental study was carried out in the Emergency department of Chauhdry Pervaiz Elahi Institute of Cardiology, Multan from to August 2008 to February 2010. A total of 120 patients with PSVT were divided in two groups. Patients in group A were treated with adenosine and group B patients received verapamil., Results: The efficacy of adenosine was proven among 56 (93%) patients, while verapamil in 43 (71%) patients. The results were statistically significant (p-value <0.05)., Conclusions: Although, both the drugs have high efficacy, adenosine is more effective than verapamil for termination of PSVT.

Background: There is no angiographically demonstrable obstructive coronary artery disease (CAD) in a significant minority of patients with myocardial infarction, particularly women. We sought to determine the mechanism(s) of myocardial infarction in this setting using multiple imaging techniques., Methods and Results: Women with myocardial infarction were enrolled prospectively, before angiography, if possible. Women with ≥50% angiographic stenosis or use of vasospastic agents were excluded. Intravascular ultrasound was performed during angiography; cardiac magnetic resonance imaging was performed within 1 week. Fifty women (age, 57±13 years) had median peak troponin of 1.60 ng/mL; 11 had ST-segment elevation. Median diameter stenosis of the worst lesion was 20% by angiography; 15 patients (30%) had normal angiograms. Plaque disruption was observed in 16 of 42 patients (38%) undergoing intravascular ultrasound. There were abnormal myocardial cardiac magnetic resonance imaging findings in 26 of 44 patients (59%) undergoing cardiac magnetic resonance imaging, late gadolinium enhancement (LGE) in 17 patients, and T2 signal hyperintensity indicating edema in 9 additional patients. The most common LGE pattern was ischemic (transmural/subendocardial). Nonischemic LGE patterns (midmyocardial/subepicardial) were also observed. Although LGE was infrequent with plaque disruption, T2 signal hyperintensity was common with plaque disruption., Conclusions: Plaque rupture and ulceration are common in women with myocardial infarction without angiographically demonstrable obstructive coronary artery disease. In addition, LGE is common in this cohort of women, with an ischemic pattern of injury most evident. Vasospasm and embolism are possible mechanisms of ischemic LGE without plaque disruption. Intravascular ultrasound and cardiac magnetic resonance imaging provide complementary mechanistic insights into female myocardial infarction patients without obstructive coronary artery disease and may be useful in identifying potential causes and therapies.
