YouTube as a Source of Patient Information Regarding Placenta Accreta Spectrum.

OBJECTIVE: As the awareness of the accompanying morbidity of placenta accreta spectrum (PAS) has increased over recent decades. We sought to analyze the precision and reliability of the currently available content regarding PAS on YouTube. STUDY DESIGN: A YouTube search was performed on June 17, 2019 by using the search terms "placenta accreta," "PAS," and "invasive placentation." Search results were sorted by relevance, and up to 200 videos per search term were systematically evaluated by four independent reviewers. A quality assessment checklist relating to aspects of PAS was developed with a Likert's scale from 0 to 12 points to quantify video content. Videos were classified as poor educational quality (grade 0 to ≤4), moderate quality (grade >4-8), and high quality (grade >8-12). RESULTS: Of the 318 videos identified, 99 videos met inclusion criteria. The majority of videos (61.6%) were produced by a professional source, that is, appearing to be from a hospital, university, or educational service. Of the remaining videos, 16.2% were classified as personal, that is, posted from personal YouTube accounts and depicting a personal or family member experience, and 22.2% were classified as other. The majority of the "other" category consisted of news segments and short clips from talk shows. Overall, 60.6% of videos were of poor educational quality, 32.3% were of moderate quality, and 7.1% were deemed high quality. All seven of the high-quality videos were produced by a professional source and intended for an audience of medical professionals. There were neither high-quality videos intended for the general public nor the likely affected and relevant patient population. CONCLUSION: This study suggests that the currently available videos on YouTube regarding PAS are poor educational sources for patients seeking information, and demonstrates a need for high-quality content videos produced by medical professionals specifically focused on meeting the needs of patient population. KEY POINTS: · Awareness of the accompanying morbidity of placenta accreta spectrum has increased over recent decades.. · YouTube videos are poor educational sources for patients seeking information regarding PAS.. · YouTube videos and all social media warrant improvements regarding patient's information..

Massive Transfusion Protocols in Obstetric Hemorrhage: Theory versus Reality.

OBJECTIVE: Massive transfusion protocols are widely implemented in obstetrical practice in case of severe hemorrhage; however, different recommendations exist regarding the appropriate ratios of blood product components to be transfused. We report our extensive experience with massive component transfusion in a referral center in which the standard massive transfusion protocol is modified by ongoing clinical and laboratory evaluation. STUDY DESIGN: A retrospective chart review of all patients who had massive transfusion protocol activation in a level 4 referral center for obstetrical practice was performed from January 2014 to January 2020. Data collected included the etiology of obstetrical hemorrhage, number of blood products of each type transfused, crystalloid infusion, and several indices of maternal morbidity and mortality. Data are presented with descriptive statistics. RESULTS: A total of 62 patients had massive transfusion protocol activation, of which 97% received blood products. Uterine atony was found to be the most common etiology for massive hemorrhage (34%), followed by placenta accreta spectrum (32%). The mean estimated blood loss was 1,945 mL. A mean of 6.5 units of packed red blood cells, 14.8 units of fresh frozen plasma and cryoprecipitate, and 8.3 units of platelets were transfused per patient. No maternal deaths were seen. CONCLUSION: The ratios of transfused packed red blood cell to fresh frozen plasma/cryoprecipitate and of packed red blood cell to platelet units varied significantly from the fixed initial infusion ratio called for by our massive transfusion protocol resulting in universally favorable maternal outcomes. When rapid laboratory evaluation of hematologic and clotting parameters is available, careful use of this information may facilitate safe modification of an initial fixed transfusion ratio based on etiology of the hemorrhage and individual patient response. KEY POINTS: · Massive transfusion protocols in obstetrics follow fixed ratios of blood products.. · Actual usage of blood components is different than the standardized protocols.. · We recommend to modify the initial fixed transfusion ratio according to clinical response..

Placenta Accreta Spectrum: Correlation between FIGO Clinical Classification and Histopathologic Findings.

OBJECTIVE: Placenta accreta spectrum (PAS) covers a wide spectrum of placental adherence/invasion with varied clinical significance. Histopathologic examination is considered the confirmatory gold standard, but is only obtained sometime after definitive treatment. The International Federation of Gynecology and Obstetrics (FIGO) has published a new clinical classification that can be assigned at delivery, and we aimed to investigate the association between this new FIGO classification and histopathology and also to assess its correlation with maternal outcomes. STUDY DESIGN: We studied a retrospective cohort of 185 patients with histopathologically proven PAS managed at our referral center between September 2012 and January 2019. Two experienced surgeons retrospectively reviewed charts and assigned the FIGO grading based on findings reported at delivery. A third experienced reviewer adjudicated to determine the classification used for final analysis. Categorical outcomes were compared with the use of chi-squared and the Fisher exact test, as appropriate. A multivariate model was designed to adjust outcomes in different FIGO groups for the involvement of a formal multidisciplinary management team. RESULTS: Among 185 patients, there were 41 (22%) placenta accreta, 44 (24%) placenta increta, and 100 (54%) placenta percreta on histopathology. The inter-rater reliability was found to be substantial with Kappa = 0.661 (p < 0.001), and 95% confidence interval (CI): 0.449-0.872. There was a significant association between all histopathology groupings and the FIGO clinical classification (p < 0.001). However, we found no association between FIGO classifications and maternal complications. CONCLUSION: The new FIGO clinical classification is strongly associated with histopathologic findings. A better understanding of the depth and extent of invasion as afforded by the clinical classification system will help standardize reporting and future research. KEY POINTS: · PAS includes a wide spectrum of placental invasion with varied clinical significance.. · Histopathological examination is considered the confirmatory gold standard.. · The new FIGO clinical classification is strongly associated with histopathologic findings..

Urologic morbidity associated with placenta accreta spectrum surgeries: single-center experience with a multidisciplinary team.

BACKGROUND: Hysterectomy for placenta accreta spectrum may be associated with urologic morbidity, including intentional or unintentional cystostomy, ureteral injury, and bladder fistula. Although previous retrospective studies have shown an association between placenta accreta spectrum and urologic morbidities, there is still a paucity of literature addressing these urologic complications. OBJECTIVE: We sought to report a systematic description of such morbidity and associated factors. STUDY DESIGN: This was a retrospective study of all histology-proven placenta accreta spectrum deliveries in an academic center between 2011 and 2020. Urologic morbidity was defined as the presence of at least one of the following: cystotomy, ureteral injury, or bladder fistula. Variables were reported as median (interquartile range) or number (percentage). Analyses were made using appropriate parametric and nonparametric tests. Multinomial regression analysis was performed to assess the association of adverse urologic events with the depth of placental invasion. RESULTS: In this study, 58 of 292 patients (19.9%) experienced urologic morbidity. Patients with urologic morbidity had a higher rate of placenta percreta (compared with placenta accreta and placenta increta) than those without such injuries. Preoperative ureteral stents were placed in 54 patients (93.1%) with and 146 patients (62.4%) without urologic injury (P=.003). After adjusting for confounding variables, multinomial regression analysis revealed that the odds of having adverse urologic events was 6.5 times higher in patients with placenta percreta than in patients with placenta accreta. CONCLUSION: Greater depth of invasion in placenta accreta spectrum was associated with more frequent and severe adverse urologic events. Whether stent placement confers any protective benefit requires further investigation.

Perinatal characteristics and early childhood follow up after ex-utero intrapartum treatment for head and neck teratomas by prenatal diagnosis.

BACKGROUND: Ex utero intrapartum treatment (EXIT) is utilized for safe delivery when a baby has a compromised airway. The purpose of this retrospective study was to examine the indications and outcomes of 11 children presenting with airway occluding oropharyngeal and cervical teratomas. METHODS: Study of all children with an airway occluding teratoma delivered via EXIT (2001-2018) in our unit. Primary outcomes included survival and tracheostomy at discharge. Data are reported using descriptive statistics as median (range) and rate (%). RESULTS: We performed 45 EXIT procedure performed between January 2001 and April 2018. Of these, eleven were for cervical and/or upper airway teratoma. Ten (91%) cases had associated polyhydramnios, two (18%) developed nonimmune hydrops, and eight (72%) delivered preterm. Six (45.5%) were performed as an emergency. Estimated blood loss was 1000 ml (500, 1000). The neonatal mortality rate was 18% (2/11) and 33% (3/9) of the survivors were discharged with a tracheostomy. CONCLUSION: EXIT is a reasonable option for delivery of babies with an occlusive upper airway mass. Neonatal survival depends on individualized factors but may be as high as 82% in those with teratoma.

In vitro fertilization as an independent risk factor for placenta accreta spectrum.

BACKGROUND: Placenta accreta spectrum is well known for its association with catastrophic maternal outcomes. However, its pathophysiology is not well defined. There have been emerging data that in vitro fertilization may be a risk factor for placenta accreta spectrum. OBJECTIVE: We investigated the hypothesis that in vitro fertilization is an independent risk factor for placenta accreta spectrum. STUDY DESIGN: A retrospective analysis of all deliveries in a prospective, population-based cohort (2012-2019) was performed in a tertiary academic center. Primary outcome variable was placenta accreta spectrum. Univariate analysis was performed on potential risk factors for predicting placenta accreta spectrum, and a multivariate model was designed to best fit the prediction of placenta accreta spectrum adjusted for risk factors such as cesarean delivery, placenta previa, age, and parity. History of previous cesarean delivery was known as a risk factor for both placenta previa and placenta accreta spectrum; hence, the interaction between "placenta previa" and "previous cesarean delivery" was included in the final model. Odds ratios were calculated as exponential of beta coefficients from the multivariate regression analysis. RESULTS: A total of 37,461 deliveries were included in this analysis, 5464 (15%) of which had a history of cesarean delivery, 281 (0.7%) had placenta previa in their index pregnancy, and 571 (1.5%) had in vitro fertilization pregnancy. The frequency of placenta accreta spectrum was 230 (0.6%). Independent risk factors for placenta accreta spectrum were in vitro fertilization pregnancy (adjusted odds ratio, 8.7; 95% confidence interval, 3.8-20.3), history of previous cesarean delivery (adjusted odds ratio, 21.1; 95% confidence interval, 11.4-39.2), and presence of placenta previa (adjusted odds ratio, 94.6; 95% confidence interval, 29.3-305.1). After adjustment for number of previous cesarean deliveries, the correlation persisted for in vitro fertilization (adjusted odds ratio, 6.7; 95% confidence interval, 2.9-15.6). CONCLUSION: Our data suggested that in vitro fertilization is an independent risk factor for placenta accreta spectrum, although its relative clinical importance compared with that of the presence of placenta previa and history of cesarean delivery is small. The pathophysiology behind this relationship remains to be investigated.

Maternal death due to COVID-19.

BACKGROUND: Despite 2.5 million infections and 169,000 deaths worldwide (as of April 20, 2020), no maternal deaths and only a few pregnant women afflicted with severe respiratory morbidity have been reported to be related to COVID-19 disease. Given the disproportionate burden of severe and fatal respiratory disease previously documented among pregnant women following other coronavirus-related outbreaks (SARS-CoV in 2003 and MERS-CoV in 2012) and influenza pandemics over the last century, the absence of reported maternal morbidity and mortality with COVID-19 disease is unexpected. OBJECTIVE: To describe maternal and perinatal outcomes and death in a case series of pregnant women with COVID-19 disease. STUDY DESIGN: We describe here a multiinstitution adjudicated case series from Iran that includes 9 pregnant women diagnosed with severe COVID-19 disease in their second or third trimester. All 9 pregnant women received a diagnosis of SARS-CoV-2 infection by reverse transcription polymerase chain reaction nucleic acid testing. Outcomes of these women were compared with their familial/household members with contact to the affected patient on or after their symptom onset. All data were reported at death or after a minimum of 14 days from date of admission with COVID-19 disease. RESULTS: Among 9 pregnant women with severe COVID-19 disease, at the time of reporting, 7 of 9 died, 1 of 9 remains critically ill and ventilator dependent, and 1 of 9 recovered after prolonged hospitalization. We obtained self-verified familial/household cohort data in all 9 cases, and in each and every instance, maternal outcomes were more severe compared with outcomes of other high- and low-risk familial/household members (n=33 members for comparison). CONCLUSION: We report herein maternal deaths owing to COVID-19 disease. Until rigorously collected surveillance data emerge, it is prudent to be aware of the potential for maternal death among pregnant women diagnosed as having COVID-19 disease in their second or third trimester.

Maternal outcomes in unexpected placenta accreta spectrum disorders: single-center experience with a multidisciplinary team.

OBJECTIVE: In a 2015 Maternal-Fetal Medicine Units Network study, only half of placenta accreta spectrum cases were suspected before delivery, and the outcomes in the anticipated cases were paradoxically poorer than in unanticipated placenta accreta spectrum cases. This was possibly because the antenatally suspected cases were of greater severity. We sought to compare the outcomes of expected vs unexpected placenta accreta spectrum in a single large US center with multidisciplinary management protocol. STUDY DESIGN: This was a retrospective cohort study carried out between Jan. 1, 2011, and June 30, 2018, of all histology-proven placenta accreta spectrum deliveries in an academic referral center. Patients diagnosed at the time of delivery were cases (unexpected placenta accreta spectrum), and those who were antentally diagnosed were controls (expected placenta accreta spectrume). The primary and secondary outcomes were the estimated blood loss and the number of red blood cell units transfused, respectively. Variables are reported as median and interquartile range or number (percentage). Analyses were made using appropriate parametric and nonparametric tests. RESULTS: Fifty-four of the 243 patients (22.2%) were in the unexpected placenta accreta spectrum group. Patients in the expected placenta accreta spectrum group had a higher rate of previous cesarean delivery (170 of 189 [89.9%] vs 35 of 54 [64.8%]; P < .001) and placenta previa (135 [74.6%] vs 19 [37.3%]; P < .001). There was a higher proportion of increta/percreta in expected placenta accreta spectrum vs unexpected placenta accreta spectrum (125 [66.1%] vs 9 [16.7%], P < .001). Both primary outcomes were higher in the unexpected placenta accreta spectrum group (estimated blood loss, 2.4 L [1.4-3] vs 1.7 L [1.2-3], P = .04; red blood cell units, 4 [1-6] vs 2 [0-5], P = .03). CONCLUSION: Our data contradict the Maternal-Fetal Medicine Units results and instead show better outcomes in the expected placenta accreta spectrum group, despite a high proportion of women with more severe placental invasion. We attribute this to our multidisciplinary approach and ongoing process improvement in the management of expected cases. The presence of an experienced team appears to be a more important determinant of maternal morbidity in placenta accreta spectrum than the depth of placental invasion.

Vasa previa: a multicenter retrospective cohort study.

OBJECTIVE: The objective of the study was to describe the characteristics and outcomes of patients with antenatal diagnosis of vasa previa and evaluate the predictive factors of resolution in a contemporary large, multicenter data set. STUDY DESIGN: This was a retrospective multicenter cohort study of all antenatally diagnosed cases of vasa previa, identified via ultrasound and electronic medical record, between January 2011 and July 2018 in 5 US centers. Records were abstracted to obtain variables at diagnosis, throughout pregnancy, and outcomes, including maternal and neonatal variables. Data were reported as median [range] or n (percentage). Descriptive statistics, receiver-operating characteristics, and logistic regression analysis were used as appropriate. RESULTS: One hundred thirty-six cases of vasa previa were identified in 5 centers during the study period, 19 (14%) of which resolved spontaneously at median estimated gestational age of 27 weeks [19-34]. All subjects with unresolved vasa previa underwent cesarean delivery at a median estimated gestational age of 34 weeks [27-39] with the median estimated blood loss of 800 mL [250-2000]. Rates for vaginal bleeding, preterm labor, premature rupture of membrane, and need for blood product transfusion were not different between the resolved and unresolved group (P = NS). The odds ratio for resolution in those with the estimated gestational age of less than 24 weeks at the time of diagnosis was 7.9 (95% confidence interval, 2.1-29.4) after adjustment for confounding variables. CONCLUSION: Our data suggest that outcomes in antenatally diagnosed cases of vasa previa are excellent. Furthermore, our data report a higher chance of resolution when the condition is diagnosed before 24 weeks of gestation.

Obstetric outcomes of ex-utero intrapartum treatment (EXIT).

BACKGROUND/PURPOSE: The ex-utero intrapartum treatment (EXIT) procedure is used to secure effective gas exchange prior to postnatal life. We describe the obstetrical course and maternal outcomes of a series of patients who underwent EXIT. METHODS: This is a review of all pregnancies in which fetuses were delivered by EXIT from January 2001 to April 2018. Outcome variables included estimated gestational age (EGA) at delivery, need for emergency EXIT, maternal estimated blood loss (EBL), need for maternal blood transfusion, and maternal postoperative length of hospital stay. Data were tested for normality and reported as median [range] and n (%). RESULTS: A total of 45 patients were delivered by EXIT procedure. Sixteen (35.6%) of the EXIT procedures were performed emergently. Median maternal EBL was 800 (500-2000) mL; 6 (13.3%) patients received blood transfusion. Median maternal postoperative length of hospital stay was four [3-7] days. CONCLUSION: Our data highlight the complexity of the obstetrical management in the EXIT procedure as evidenced by an approximately 36% chance of emergency delivery. Despite having an experienced multidisciplinary team, 13.3% of our subjects underwent maternal blood transfusion. This information can be used in counseling EXIT candidates regarding the risks and benefits of this procedure.

Primary fetal pleural effusion: Characteristics, outcomes, and the role of intervention.

BACKGROUND: We aimed to present the natural history and outcomes of fetal primary pleural effusions (PPE). METHODS: Fetuses with prenatal diagnosis of PPE delivered between January 2011 and June 2018 were included. Fetal PPE were separated into groups: resolved, stable, or progressive. Progressive PPE was diagnosed, using fetal echocardiography, by the new onset of fetal hydrops or impaired cardiac function. Data were reported as median [range] and n (%). RESULTS: Among 189 fetuses with antenatal diagnosis of pleural effusion, 30 had a PPE. A total of 26.7% (n = 8), 26.7% (n = 8), and 40.0% (n = 12) were classified as resolved, stable, and progressive, respectively; two were lost to follow-up. In 14 cases (50%), there were bilateral pleural effusions. Of the 12 cases in the progressive group, four (33.3%) had amnioreduction, six (50.0%) had thoracentesis, and eight (66.7%) had shunt placement performed. There were two fetal deaths, both in the progressive group, one of which received amnioreduction and the other underwent both thoracentesis and shunt placement prior to demise. CONCLUSION: In more than half of fetuses with prenatal PPE, the effusion remained stable or spontaneously resolved, and the perinatal outcomes were generally favorable. This information will be useful in optimizing the counseling and care of these patients.

Severe fetal hemolytic disease due to anti-M alloimmunization: A case report and literature review.

Fetal hemolysis is caused by maternal antibodies that cross the placenta. Anti-M antibodies can rarely cause severe forms of alloimmunization in the fetus and newborn. We present a case of severe anti-M alloimmunization requiring a total of 8 intrauterine transfusions, in a patient with a prior poor obstetrical history. A 35-year-old Iranian pregnant woman with a prior obstetrical history of one abortion and two stillbirths was found to have had anti-M antibody titers 1:8 and accompanying elevated middle cerebral artery peak systolic velocity (MCA-PSV) of 1.9 MoM suggestive of severe fetal anemia at 17 weeks of gestation. Persistently elevated fetal MCA-PSV was noted despite intraperitoneal transfusion at 17, 19, and 22 weeks. Fetal blood sampling at 27 weeks confirmed severe fetal anemia (3 g/dL), which required additional intravascular and intraperitoneal blood transfusion. At 37 weeks, elective cesarean section was performed. Neonatal hemoglobin immediately after delivery was 10.1 g/dL. In addition to standard supportive care, the neonate required two additional transfusions and remained in the neonatal intensive care unit (NICU) for 23 days. Anti-M antibodies are a rare cause of severe alloimmunization. We present a case in order to improve management.

Clinical Correlates of Placenta Accreta Spectrum Disorder Depending on the Presence or Absence of Placenta Previa: A Systematic Review and Meta-analysis.

OBJECTIVE: To evaluate whether there are differences in risk factors and maternal outcomes of pregnancies complicated by placenta accreta spectrum depending on the presence or absence of placenta previa. DATA SOURCES: We performed a systematic search in Medline, EMBASE, ClinicalTrials.gov , and Web of Science from inception through April 25, 2022, without language or date restrictions. Search strategy included the key words "placenta accreta," "placenta increta," "placenta percreta," "adherent placenta," "invasive placenta," "abnormal placent*," "placenta previa," and "marginal placent*." METHODS OF STUDY SELECTION: Of the 1,122 articles screened, seven studies were included in the final review. Studies were included if they compared the risk factors and maternal outcomes of pregnancies complicated by placenta accreta spectrum depending on the presence or absence of placenta previa. TABULATION, INTEGRATION, AND RESULTS: A random-effects model was used to pool the mean differences or odds ratios (OR) and the corresponding 95% CIs using RevMan software. A total of 3,342 pregnancies complicated by placenta accreta spectrum were included in the meta-analysis (2,365 without previa and 977 with previa). Pregnancies complicated by placenta accreta spectrum without previa were more likely to have been conceived by in vitro fertilization (IVF) (OR 3.11, 95% CI 1.93-5.02, P <.001, I 2 =52.0%) and to be associated with prior dilation and curettage (D&C) (OR 1.60, 95% CI 1.15-2.22, P =.005, I 2 =0.0%) and myomectomy (OR 2.47, 95% CI 1.31-4.66, P =.005, I 2 =0.0%), but they were less likely to be associated with prior cesarean delivery (OR 0.15, 95% CI 0.06-0.37, P <.001, I 2 =87.0%). Placenta accreta spectrum without previa was less likely to be diagnosed antenatally (OR 0.07, 95% CI 0.04-0.11, P <.001, I 2 =38.0%). Also, women with pregnancies without previa had lower rates of red blood cell transfusion, intensive care unit admission, risk of hysterectomy, unscheduled delivery, and intraoperative bowel or bladder injuries. CONCLUSION: Pregnancies complicated by placenta accreta spectrum without previa had a more prominent association with IVF and prior D&C and myomectomy but were much less likely to be associated with prior cesarean delivery. Further, placenta accreta spectrum without previa was less likely to be diagnosed antenatally, although it had better maternal outcomes as compared with placenta accreta spectrum with previa.

Placenta Accreta Spectrum Without Placenta Previa.

OBJECTIVE: To evaluate placenta accreta spectrum with and without placenta previa with regard to risk factors, antepartum diagnosis, and maternal morbidity. METHODS: We conducted a retrospective cohort study of pathology-confirmed placenta accreta spectrum deliveries with hysterectomy from two U.S. referral centers from January 2010-June 2019. Maternal, pregnancy, and delivery characteristics were compared among placenta accreta spectrum cases with (previa PAS group) and without (nonprevia PAS group) placenta previa. Surgical outcomes and a composite of severe maternal morbidities were evaluated, including eight or more blood cell units transfused, reoperation, pulmonary edema, acute kidney injury, thromboembolism, or death. Logistic regression was used with all analyses controlled for delivery location. RESULTS: Of 351 deliveries, 106 (30%) had no placenta previa at delivery. When compared with the previa group, nonprevia placenta accreta spectrum was less likely to be identified antepartum (38%, 95% CI 28-48% vs 87%, 82-91%), less likely to receive care from a multidisciplinary team (41%, 31-51% vs 86%, 81-90%), and less likely to have invasive placenta increta or percreta (51% 41-61% vs 80%, 74-84%). The nonprevia group had more operative hysteroscopy (24%, 16-33% vs 6%, 3-9%) or in vitro fertilization (31%, 22-41% vs 9%, 6-13%) and was less likely to have had a prior cesarean delivery (64%, 54-73% vs 93%, 89-96%) compared with the previa group, though the majority in each group had a prior cesarean delivery. Rates of severe maternal morbidity were similar in the two groups, at 19% (nonprevia) and 20% (previa), even after controlling for confounders (adjusted odds ratio for the nonprevia group 0.59, 95% CI 0.30-1.17). CONCLUSION: Placenta accreta spectrum without previa is less likely to be diagnosed antepartum, potentially missing the opportunity for multidisciplinary team management. Despite the absence of placenta previa and less placental invasion, severe maternal morbidity at delivery was not lower. Broader recognition of patients at risk for placenta accreta spectrum may improve early clinical diagnosis and patient outcomes.

Ultrasound measurement of fetal adrenal gland in fetuses with intrauterine growth restriction, an early predictive method for adverse outcomes.

OBJECTIVES: Comparing the sonographic measurements of fetal adrenal gland in pregnancies with intrauterine growth restriction (IUGR) versus healthy controls and to assess whether the changes in adrenal gland measurements could predict adverse pregnancy outcomes in IUGR fetuses. METHODS: This prospective cohort study evaluated 97 pregnant women (48 with IUGR pregnancies and 49 healthy controls) during their third gestational trimester. All mothers underwent two dimensional ultrasonography of the fetal adrenal gland, and the fetal zone in transverse, sagittal, and coronal planes. Adrenal gland volume (AGV) and fetal zone volume (FZV) were calculated and corrected (c) for fetal weight. The mothers were then followed until delivery. RESULTS: Fetuses in the IUGR group had larger corrected adrenal gland volume (c_AGV) and smaller corrected fetal zone volume (c_FZV) compared to the fetuses in the control groups (p < .001). In the IUGR group, significantly smaller c_AGV and higher fetal/adrenal were detected in IUGR fetuses who had nonreassuring fetal status before delivery, preterm birth, very low birth weight delivery, and also those who required neonatal intensive care unit admission (p < .01 for all). CONCLUSIONS: Third trimester fetal adrenal gland sonography could potentially be used as an easy noninvasive method for identifying those IUGR fetuses who might have poorer outcomes.

Amnioreduction in cases of polyhydramnios: Indications and outcomes in singleton pregnancies without fetal interventions.

OBJECTIVE: To evaluate indications, pregnancy outcomes, and risk of adverse events following amnioreduction procedures in singleton gestations. STUDY DESIGN: Study of all amnioreduction procedures performed on singleton gestations complicated by polyhydramnios between January 2011 and June 2018 at our tertiary and regional referral fetal center. Clinical indications for amnioreduction procedures were categorized as either maternal shortness of breath, perceived abdominal tightness, or preterm uterine contractions with or without cervical change. Our primary outcome(s) of interest were: preterm premature rupture of membranes (PPROM), placental abruption, chorioamnionitis and/or preterm delivery, each in isolation or as a composite. RESULTS: Among 358 patients who underwent amnioreduction in the study period, 251 arose from cases of twin-twin transfusion syndrome (TTTS) and 74 were singletons undergoing additional fetal intervention procedures. Each of the remaining 33 patients underwent a median number of one [range 1-12] amnioreductions over the antepartum interval, yielding a total of 66 amnioreduction procedures. Among the study cohort, there were no instances of PPROM, placental abruption, chorioamnionitis or preterm delivery within the 12 h following the procedure but 10.6% experienced preterm delivery within 48 h of amnioreduction. CONCLUSION: Our data suggests that among singleton gestations, there was a low risk for preterm delivery in close proximity to the procedure and none experienced rupture of membranes, placental abruption, sepsis, fetal demise or neonatal death. This data may be used in counseling of potential candidates for amnioreduction with singleton pregnancies and symptomatic polyhydramnios.

Age related endocrine patterns observed in polycystic ovary syndrome patients vs. ovulatory controls: descriptive data from a university based infertility center.

Objective: To compare serum anti-Müllerian hormone (AMH) and other endocrine parameters between patients diagnosed with polycystic ovary syndrome (PCOS) and age-matched ovulatory women. Materials and methods: AMH, DHEAS, FSH, LH, PRL, TSH and total testosterone (TT) were prospectively measured in oligo-ovulatory PCOS patients (n = 595) and in ovulatory non-PCOS women (n = 157) referred to a tertiary infertility center. Mean BMI was similar across the two study populations and there were no smokers in the sample. Patients in both groups were further classified into three categories by age: < 25 yrs, 25-34 yrs, and ≥ 35 yrs. Selected clinical and demographic characteristics were tabulated for each group. Results: Serum AMH was significantly higher among PCOS patients compared to non-PCOS controls in the non-stratified sample (7.54 ± 5.8 vs. 2.49 ± 2.0 ng/mL, respectively; p < 0.0001), while serum FSH, DHEAS, TSH and prolactin were similar for both groups (p > 0.05). As expected, mean (total) testosterone levels were notably different between PCOS vs. non-PCOS controls (0.84 ± 0.76 vs. 0.43 ± 0.38 ng/mL, respectively; p < 0.001), and mean AMH level was significantly lower in the oldest age category (> 35 yrs) compared to both younger control groups (p < 0.0001). Both DHEAS and total testosterone decreased with age among PCOS patients, although mean serum DHEAS for women age > 35 yrs was significantly lower than DHEAS measured in younger women with PCOS (p < 0.02). For PCOS patients, AMH remained relatively stable irrespective of age. Conclusion: Although AMH can serve as a satisfactory marker of ovarian reserve, for PCOS patients the expected decline in AMH associated with reproductive aging appears attenuated despite ovarian senescence. In contrast, mean DHEAS levels were markedly lower among older PCOS women (> 35 yrs) compared to younger PCOS patients.
