Pre-eclampsia (PE) is a hypertensive disorder characterised by systemic vascular resistance and endothelial dysfunction. It is known to influence choroidal thickness (CT). No previous studies have explored the antepartum and postpartum changes in CT with respect to the protein-creatinine ratio (PCR), a measure of proteinuria that is a clinical hallmark of PE. This study evaluated the correlations between antepartum and postpartum CT and the PCR in patients with PE. In this retrospective study, sixty-six eyes (66 patients) were analysed. The patients were divided into two groups according to the median PCR value (2.36 mg/mg): low PCR group (< 2.36 mg/mg) and high PCR group (≥ 2.36 mg/mg). Ophthalmologic clinical data were collected and assessed. We observed higher antepartum CT and higher mean arterial pressure in high PCR group than in low PCR group. Moreover, postpartum CT decreased significantly in high PCR group. In the multivariate analysis, CT changes were correlated with antepartum CT and antepartum PCR after logarithm transformation. In conclusion, a greater decrease in CT was observed in high PCR group than in low PCR group. Further, the antepartum PCR showed a correlation with the extent of CT reduction.

Review
Obstetric hemorrhage, with its related complications, remains a significant and often preventable cause of maternal morbidity and mortality. The medical community has made strides in beginning to address the impact of obstetric hemorrhage as a cause of maternal morbidity and mortality with standardized bundles outlining key elements for hospitals to address in order to optimize hemorrhage prevention and management. Changes in definitions, an expansion of the spectrum of causes, variation in interventions and guidelines and lack of innovation are some of the issues that pose ongoing challenges for meaningful risk reduction. Opportunities to support risk reduction include helping to secure necessary resources, building team training and simulation programs, developing interventions targeted at minimizing cognitive biases, and facilitating patient and family support program development.

Review
Congenital fibrinogen disorders are a group of most frequent rare coagulation disorder, characterized by deficiency and/or defects in the fibrinogen molecule. Quantitative disorders include hypofibrinogenemia and afibrinogenemia. Due to their specific physiological characteristics, female patients tend to have congenital hypofibrinogenemia/afibrinogenemia, such as spontaneous recurrent abortion, menorrhagia, infertility, antepartum and postpartum hemorrhage, and so on. Current studies of congenital hypofibrinogenemia/afibrinogenemia mainly focus on different types of fibrinogen mutations, etiology/pathogenesis, and some rare case reports of the diseases. So far, there is no study available to systematically review the specific features of female patients with congenital bleeding disorders. This review aims to deal with hematological, gynecologic and obstetric issues, and relevant clinical management of congenital hypofibrinogenemia/afibrinogenemia at different life stages of female patients. We believe this review provides valuable reference for clinicians in the field of hematology, obstetrics, as well as gynecology.

Review
OBJECTIVE
To identify the accuracy of diagnosing postpartum diabetes and glucose intolerance using antepartum glycosylated hemoglobin (HbA1c) and fasting glucose values.
STUDY DESIGN
A retrospective Hawaiian cohort of women with gestational diabetes during 2004-2011 were evaluated. Antepartum HbA1c and postpartum 75-g glucose tolerance tests were obtained.
RESULTS
An antepartum HbA1c value of ≥6.5% had a 45.7% sensitivity, a 96% specificity and a 40% positive predictive value (PPV) for predicting postpartum diabetes. An antepartum HbA1c value of ≥6.5% had a 6.6% sensitivity, a 94.2% specificity and a 27% PPV for predicting postpartum impaired glucose tolerance. An antepartum HbA1c value of ≥6.5% had a 10.3% sensitivity, a 95.7% specificity and a 33.3% PPV for predicting postpartum impaired fasting glucoses.
CONCLUSION
We could not demonstrate a clinically useful PPV for diagnosing postpartum diabetes or glucose intolerance using an antepartum elevated HbA1c value of ≥6.5% or a fasting glucose level of ≥90 mg/dL.

Review
Obesity is a significant global health problem. It results in a higher incidence of complications for pregnant women and their neonates. Cesarean deliveries are more common in obese parturients as well. The increased burden of comorbidities seen in this population, such as obstructive sleep apnea, necessitates antepartum anesthetic consultation. These patients pose unique challenges for the practicing anesthesiologist and may benefit from optimization prior to delivery. Complications from anesthesia and overall morbidity and mortality are higher in this population. Neuraxial anesthesia can be challenging to place in the obese parturient, but is the preferred anesthetic for cesarean delivery to avoid airway manipulation, minimize aspiration risk, prevent fetal exposure to volatile anesthetic, and decrease risk of post-partum hemorrhage from volatile anesthetic exposure. Monitoring and positioning of these patients for surgery may pose specific challenges. Functional labor epidural catheters can be topped up to provide conditions suitable for surgery. In the absence of a working epidural catheter, a combined spinal epidural anesthetic is often the technique of choice due to relative ease of placement versus a single shot spinal technique as well as the ability to extend the anesthetic through the epidural portion. For cesarean delivery with a vertical supraumbilical skin incision, a two-catheter technique may be beneficial. Concern for thromboembolism necessitates early mobilization and a multimodal analgesic regimen can help accomplish this. In addition, thromboprophylaxis is recommended in this population after delivery-especially cesarean delivery. These patients also need close monitoring in the post-partum period when they are at increased risk for several complications.

INTRODUCTION AND AIM
Antepartum hemorrhage (APH) is one of the deadliest complications in obstetrics. It can complicate about 2-5% of pregnancies. It contributes significantly to maternal and perinatal mortality and morbidity during pregnancy and childbearing worldwide. The aim of this study was to determine maternal and fetal outcomes in patients presenting with APH.
MATERIALS AND METHODS
This was a retrospective study. Pregnant women with >28 weeks gestation reporting to the Department of Obstetrics and Gynecology from May 2021 to April 2022 were included in the study. Ethical approval from the institutional ethical committee was taken.
RESULT
This study included 76 patients of APH. Most patients in the analysis were found to be second gravida (30%). Anemia was the most common associated morbidity (51.31%). 58% of these patients were of placenta previa, 14% were of abruption, and 10% were of accreta. Among all patients, 94.74% recovered well. 2.63% of cases could not be saved and resulted in maternal mortality. The proportions of babies alive, intra-uterine death (IUD), and intubated were 86.84%, 11.84%, and 1.32%, respectively. 17.1% of patients required a lifesaving cesarean hysterectomy.
CONCLUSION
APH is an obstetrical emergency that requires timely diagnosis and early intervention. Swift management is required to improve maternal and fetal outcomes.

Review
Timing of cortisol collection during pregnancy is an important factor within studies reporting on the association between maternal cortisol and depression during pregnancy. Our objective was to further examine the extent to which reported associations differed across studies according to time of maternal cortisol collection during pregnancy. On December 15, 2016, records were identified using PubMed/MEDLINE (National Library of Medicine), EMBASE (Elsevier; 1974-), Cumulative Index to Nursing and Allied Health Literature (CINAHL, EBSCO), PsycINFO (EBSCO), and Web of Science Core Collection (Thomson Reuters). Unique abstracts were screened using the following inclusion criteria: (1) maternal cortisol assessed during pregnancy; (2) antepartum depression assessed during pregnancy using a screening instrument; (3) reports on the association between maternal cortisol and antepartum depression; (4) provides information on timing of cortisol assessment during pregnancy, including time of day and gestation; and (5) not a review article or a case study. One thousand three hundred seventy-five records were identified, resulting in 826 unique abstracts. Twenty-nine articles met all inclusion criteria. On balance, most studies reported no association between maternal cortisol and antepartum depression (N = 17), and saliva and blood were the most common reported matrices. Morning and second and third trimesters were the most common times of collection during pregnancy. Among studies reporting an association (N = 12), second-trimester and third-trimester cortisol assessments more consistently reported an association and elevated cortisol concentrations were observed in expected recovery periods. Our review adds to the existing literature on the topic, highlighting gaps and strategic next steps.

American Journal of Obstetrics &... Nov 2021There are few population-based studies of antepartum emergency department visits and inpatient hospitalizations and their implications for delivery outcomes.
BACKGROUND
There are few population-based studies of antepartum emergency department visits and inpatient hospitalizations and their implications for delivery outcomes.
OBJECTIVE
The study aimed to analyze the likelihood of pregnant patients's antepartum hospital use using population-based hospital discharge data for births in California. The study analyzed associations between antepartum hospital use and the likelihood of maternal delivery complications and postpartum hospital use.
STUDY DESIGN
This was a population-based retrospective cohort study of individuals with live births in state-licensed hospitals in California in 2017. Delivery admissions data were linked to antepartum hospital visits within 280 days of a delivery admission and 90 days after a delivery discharge. The most common principal or primary International Classification of Diseases, Tenth Revision-coded diagnoses for antepartum emergency department visits and inpatient hospitalizations were identified and Poisson regression estimates were used to determine the likelihood of antepartum hospital use by maternal demographic and clinical characteristics. Complicated deliveries were defined by International Classification of Diseases, Tenth Revision-coded severe maternal morbidity, vaginal or cesarean delivery complications, or long length of stay after delivery (>4 days for a vaginal delivery and >5 days for a cesarean delivery). Associations between specific types of antepartum visits, complicated deliveries, and postpartum hospital use were analyzed by chi-square tests. Logistic regression estimates were used to determine the significance of associations between antepartum hospital use and likelihood of a complicated delivery.
RESULTS
Of 348,848 deliveries at 246 hospitals in California, in 2017, with linkable data, almost one-third of the patients (30.4% with emergency department visits and 1.2% with inpatient hospital stays) experienced antepartum hospital use. Those who were younger, identified as a racial or ethnic minority, and with a low income, were the most likely to have antepartum hospital use. The most common primary diagnoses for antepartum emergency department visits were threatened abortions (19.6%), urinary tract infections (11.2%), and hemorrhage (9.3%). The most common principal diagnoses for antepartum hospitalizations were preterm labor (14.3%), pyelonephritis (10.2%), and hyperemesis gravidarum (6.3%). Patients with any antepartum hospital use were significantly more likely to experience a delivery complication, even after controlling for conditions coded during the delivery admission. Although having an antepartum emergency department visit was associated with only modestly increased adjusted odds (odds ratio, 1.04; 95% confidence interval, 1.01-1.08) of a complicated delivery, patients with any antepartum hospitalizations, especially those with preterm prelabor rupture of membranes, hypertension, diabetes, or hemorrhage, were at higher risk (odds ratio, 1.38; 95% confidence interval, 1.28-1.47).
CONCLUSION
Antepartum hospital use is frequent and is associated with patient clinical and demographic factors. Addressing the high prevalence of antepartum hospital use should be a part of future quality improvement and health equity efforts focused on improving care for patients with the greatest medical and social needs.

Observational Study
INTRODUCTION
Because most data on placental abruption are derived from retrospective studies, multiple sources of bias may have affected the results. Thus, we aimed to characterize risk factors and outcomes for placental abruption in a large prospective cohort of nulliparous women.
METHODS
This was a secondary analysis of women enrolled in the Nulliparous Pregnancy Outcomes Study Monitoring-to-be (nuMom2b) study, a prospective observational cohort. Participants were recruited in their first trimester of pregnancy from 8 sites and had 4 study visits, including at delivery. Placental abruption was defined by confirmed clinical criteria. The primary analysis was restricted to abruption identified antepartum and intrapartum. As a secondary analysis, we examined antepartum and intrapartum abruptions separately. We compared risk factors (maternal demographic and clinical characteristics) and outcomes in women with and without placental abruption using univariable and multivariable analyses as appropriate.
RESULTS
9450 women were included in the primary analysis. Abruption was identified in 0.66% ( = 62), of which 35 (56%) were antepartum and 27 (44%) intrapartum. For women with abruption, the mean gestational age at delivery was 35.6 ± 4.4 weeks and 38.8 ± 2.2 weeks for women without abruption. Gravidity was associated with abruption (OR 3.1, 95% CI: 1.6-6.0). In univariate analysis, abruption was associated with cesarean delivery (OR 3.7, 95% CI: 2.2-6.0), blood transfusion (OR 3.8, 95% CI: 1.4-10.7), PPROM (OR 9.0, 95% CI: 5.4-15.1), preterm birth (OR 8.5, 95% CI: 5.1-14.2), SGA (OR 4.0, 95% CI: 2.3-6.95), RDS (OR 5.5, 95% CI: 2.6-11.2), IVH 20.2 (OR 20.2, 95% CI: 5.9-68.8) and ROP (OR 12.2, 95% CI: 2.8-52.6). However, after adjustment for confounders including gestational age, abruption was only associated with increased odds of cesarean delivery and blood transfusion. Results were similar when restricted to antepartum and intrapartum abruptions.
CONCLUSION
Abruption was identified in <1% of nulliparous women. However, few maternal risk factors were identified. Neonatal morbidities were associated with an abruption and were primarily driven by gestational age due to preterm birth.

Review
The fields of Obstetrics and Gynecology and Critical Care often share medically and surgically complex patients. Peripartum anatomic and physiologic changes can predispose or exacerbate certain conditions and rapid action is often needed. This review discusses some of the most common conditions responsible for the admission of obstetrical and gynecological patients to the critical care unit. We will consider both obstetrical and gynecologic concepts including postpartum hemorrhage, antepartum hemorrhage, abnormal uterine bleeding, preeclampsia and eclampsia, venous thromboembolism, amniotic fluid embolism, sepsis and septic shock, obstetrical trauma, acute abdomen, malignancies, peripartum cardiomyopathy, and substance abuse. This article aims to be a primer for the Critical Care provider.
