Mean Arterial Pressure and Neonatal Outcomes in Pregnancies Complicated by Mild Chronic Hypertension.

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

Uterine Prolapse in Pregnancy: A Review.

Importance: Although not a common occurrence, uterine prolapse during pregnancy can have significant effects for pregnancy outcomes and quality of life of maternal patients. Most data about management exist as case reports; a review of these cases provides some guidance about treatment options. Objectives: This review examines current literature about uterine prolapse during pregnancy to assess current information about this condition, prevalence, diagnosis, management, and outcomes. Evidence Acquisition: Electronic databases (PubMed and Embase) were searched using terms "uterine prolapse" AND "pregnancy" AND "etiology" OR "risk factors" OR "diagnosis" OR "therapy" OR "management" limited to the English language and between the years 1980 and October 31, 2022. Results: Upon review of 475 articles, 48 relevant articles were included as well as 6 relevant articles found on additional literature review for a total of 54 articles. Of those articles, 62 individual cases of uterine prolapse in pregnancy were reviewed including pregnancy complications, mode of delivery, and outcomes. Prevalence was noted to be rare, but much more common in second and subsequent pregnancies. Most diagnoses were made based on symptomatic prolapse on examination. Management strategies included bed rest, pessary use, and surgery (typically during the early second trimester). Complications included preterm delivery, patient discomfort, urinary retention, and urinary tract infection. Delivery methods included both cesarean and vaginal deliveries. Conclusions: Although a rare condition, uterine prolapse in pregnancy is readily diagnosed on examination. Reasonable conservative management strategies include observation, attempted reduction of prolapse, and pessary use; if these measures fail, surgical treatment is an option. Relevance: Our review compiles literature and known cases of uterine prolapse during pregnancy and current evidence about prevalence, diagnosis, management, outcomes, and complications of uterine prolapse during pregnancy in order to inform our target audience in their clinical practice.

Thick Placenta in Pregnancy: A Review.

Importance: A thickened placenta is easily identified on ultrasound and provides insight into maternal and fetal wellbeing as well as underlying structural and physiologic anomalies. Objectives: The aim of this study was to review the literature to clarify what classifies a placenta as "thickened" and to review the associated incidence, maternal and fetal comorbidities, and management during pregnancy. Evidence Acquisition: Electronic databases (PubMed and Web of Science) were searched from 2000 to 2020 in the English language. Studies were selected that examined associations between placental thickness, potential etiologies, and obstetric outcomes. Results: There were 140 abstracts identified. After reviewing the articles, 60 were used in this review. Routine assessment of the placenta in the prenatal period is an easy and inexpensive way to assess the maternal and fetal patients. The criteria for a "thickened placenta" vary between studies based on gestational age, placental location, measurement technique, and maternal or fetal factors. Whereas most suggest thickness exceeding 4 cm is pathologic, a review had a threshold of 6 cm in the third trimester to classify placentomegaly. Several maternal and fetal conditions have been associated with a thickened placenta, such as obesity, parity, anemia, diabetes, preeclampsia, cardiac dysfunction, infection, assisted reproductive technology, multiple pregnancy, sacrococcygeal teratomas, and Beckwith-Wiedemann syndrome. A thickened placenta in pregnancy is associated with a higher incidence of adverse pregnancy outcomes and neonatal morbidity and mortality. Conclusions: The literature is clear that early evaluation of the placenta using ultrasound should be a standard practice. A thickened placenta found on routine imaging should prompt a more thorough investigation to determine the etiology of the placentomegaly. At the time of this literature review, there are no recommendations regarding modality or frequency of antenatal surveillance in pregnancies complicated by a thickened placenta. However, serial ultrasounds and weekly antenatal testing in the third trimester should be considered. Relevance: A thickened placenta has been associated with a variety of maternal and fetal conditions and increases the risk of adverse pregnancy outcomes and neonatal morbidity and mortality.

The Impact of Adenomyosis on Pregnancy and Pregnancy Outcomes: A Review.

Objective: The aim of this review was to describe the risk factors, diagnosis, and effects on pregnancy of the gynecologic condition adenomyosis. Methods: A PubMed, Web of Science, and CINAHL search was undertaken. Citations were limited to the past 30 years. Results: There were 223 articles identified, with 31 articles being the basis of this review. Adenomyosis is a relatively common gynecologic condition that was previously thought to predominantly occur in older women, as it was diagnosed most commonly after a hysterectomy. As imaging techniques have advanced, this condition is now able to be diagnosed much earlier in life and is estimated to affect up to 20% of reproductive aged women. As studies have followed these women through subsequent pregnancies, an increased risk of adverse pregnancy outcomes has been observed. These include miscarriage, preterm birth, preterm prelabor rupture of membranes, small for gestational age, low birthweight, and preeclampsia, among others. This review is to examine the incidence, risk factors, and diagnostic criteria of adenomyosis and to then discuss its role in adverse pregnancy outcomes. Conclusions: Adenomyosis has been predominately a gynecologic condition, but now has been shown to adversely affect pregnancy outcomes. Diagnosis is made with histology, but may be suspected based on magnetic resonance imaging and ultrasound findings. Despite evidence of adverse pregnancy outcomes, there are no established strategies to risk, stratify, or prevent any of these outcomes.

Are the Diagnosis and Treatment of Acute Cystitis in the Premenopausal, Pregnant, and Postmenopausal Women the Same? A Review of the Literature.

Importance: Acute cystitis is a common condition diagnosed in women. The diagnosis and treatment of this condition change throughout a woman's life. Understanding the differences in diagnosis and treatment in premenopausal, pregnant, and postmenopausal woman increases the likelihood of treatment success and decreases risk of complications from untreated or suboptimally treated infections. Objective: The aim of this review is to describe the incidence, risk factor, pathophysiology, diagnosis, and management of acute cystitis and the similarities and differences of these aspects of the condition in the premenopausal, pregnant, and postmenopausal woman. Evidence Acquisition: A PubMed, Web of Science, and CINAHL search was undertaken with the years 1990 to 2020 searched. Results: There were 393 articles identified, with 103 being the basis of review. Multiple risk factors for acute cystitis have been identified and are largely consistent throughout a woman's lifetime with few exceptions. The diagnoses by group with common diagnostic tools, such as urinalysis, vary in specificity and sensitivity between these groups. Management also varies between groups, with pregnancy having specific limitations related to drug safety in regard to possible fetal effects posed by certain medications commonly used to treat acute cystitis. Conclusions: Acute cystitis not only varies in presentation throughout a woman's lifespan, but also in appropriate diagnosis and treatment. Treatment of acute cystitis does have some commonalities between the groups; however, there are contraindications unique to each group. These differences are paramount to not only ensuring appropriate treatment but also treatment success. Relevance: Acute cystitis is a common condition with different diagnostic and management recommendations throughout a woman's lifespan.

Signet Ring Cell Carcinoma with Lymphangitic Carcinomatosis in Pregnancy: A Case Report of an Unexpected Maternal Death and Review of the Literature.

BACKGROUND Cancer in pregnancy is extremely rare, and gastric cancers are rarer still. Diagnosis is difficult in pregnancy due to overlapping symptoms with pregnancy such as nausea, pain, anemia, and fatigue. CASE REPORT A 26-year-old G1 woman at 32 weeks gestation with a past medical history of systemic lupus erythematosus presented with new-onset chest pain and shortness of breath. Computed tomography of the chest, electrocardiogram, and echocardiogram were normal. Laboratory evaluation revealed thrombocytopenia, proteinuria of 480 milligrams, and normal complement. She delivered on hospital day 3 due to worsening chest pain. During cesarean delivery, the patient became hypotensive and hypoxic and required intensive care unit admission after a cesarean hysterectomy. On postoperative day 2 she had a pulmonary embolus and was started on therapeutic anticoagulation. She clinically improved until postoperative day 4, when she was found unresponsive with pulseless electrical activity. After 38 minutes of Advanced Cardiac Life Support, death was pronounced. An autopsy was performed and the cause of death found to be complications of multi-organ system involvement of adenocarcinoma with signet ring cell features. Lymphangitic carcinomatosis was noted throughout the lungs. CONCLUSIONS This patient had adenocarcinoma with signet ring cell features and associated lymphangitic carcinomatosis, which led to her postpartum death. Lymphangitic carcinomatosis is associated with an exceedingly poor prognosis, especially in pregnancy.

Diagnosis and Management of Placental Mesenchymal Disease. A Review of the Literature.

OBJECTIVE: To review what is currently known about placental mesenchymal dysplasia (PMD) including imaging techniques for diagnosis and differentiation from a molar pregnancy, genetics, maternal/fetal effects, and management. EVIDENCE ACQUISITION: A literature search by research librarians at 2 universities was undertaken using the search engines PubMed and Web of Science. The search terms used were "etiology" OR "cause" OR "risk" OR "risks" OR "epidemiology" OR "diagnosis" OR "therapy" OR "prognosis" OR "management" AND "placental mesenchymal dysplasia" OR "placenta" AND "mesenchymal dysplasia." No limit was put on the number of years searched. RESULTS: The etiology of PMD remains uncertain, although there are a number of theories on causation. An elevated maternal serum α-fetoprotein level, slightly elevated human chorionic gonadotropin level, normal karyotype, multicystic lesions on ultrasound, and varying degrees of flow within cysts using color Doppler (stained-glass appearance) are helpful in making the diagnosis. On pathologic examination of the placenta, PMD is differentiated from molar pregnancy by the absence of trophoblastic hyperplasia. Fetal complications of PMD include hematologic disorders, Beckwith-Wiedemann syndrome, liver tumors, fetal growth restriction, preterm delivery, and intrauterine fetal demise. Maternal complications include gestational hypertension, preeclampsia, HELLP (hemolysis, elevated liver function tests, low platelets) syndrome, and eclampsia. CONCLUSIONS: Accurate diagnosis of PMD is imperative for appropriate management and surveillance to minimize adverse maternal and fetal outcomes. RELEVANCE: The importance of a correct diagnosis of PMD is important because it can be misdiagnosed as a partial molar pregnancy or a complete mole with coexisting normal fetus, and this can result in inappropriate management.

Use of Electronic Nicotine Delivery Systems (ENDS) by pregnant women I: Risk of small-for-gestational-age birth.

INTRODUCTION: The 2016 US Surgeon General's Report suggests that the use of electronic nicotine delivery systems (ENDS) is a fetal risk factor. However, no previous study has estimated their effect on adverse pregnancy outcomes. We assessed the prevalence of current ENDS use in pregnant women and explored the effect on birth weight and smallness-for-gestational-age (SGA), correcting for misclassification from nondisclosure of smoking status. METHODS: We conducted a cohort study with 248 pregnant women using questionnaire data and biomarkers (salivary cotinine, exhaled carbon monoxide, and hair nicotine). We evaluated the association between birth weight and the risk of SGA by applying multivariate linear and log-binomial regression to reproductive outcome data for 232 participants. Participants who did not disclose their smoking status were excluded from the referent group. Sensitivity analysis corrected for misclassification of smoking/ENDS use status. RESULTS: The prevalence of current ENDS use among pregnant women was 6.8% (95% CI: 4.4-10.2%); most of these (75%) were concurrent smokers. Using self-reports, the estimated risk ratio of SGA for ENDS users was nearly two times the risk in the unexposed (RR=1.9, 95% CI: 0.6-5.5), and over three times that for ENDS-only users versus the unexposed (RR=3.1, 95% CI: 0.8-11.7). Excluding from the referent group smokers who did not disclose their smoking status, the risk of SGA for ENDS-only use was 5 times the risk in the unexposed (RR=5.1, 95% CI: 1.1- 22.2), and almost four times for all types of ENDS users (RR=3.8, 95% CI: 1.3-11.2). SGA risk ratios for ENDS users, corrected for misclassification due to self-report, were 6.5-8.5 times that of the unexposed. CONCLUSIONS: Our data suggest that ENDS use is associated with an increased risk of SGA.

Use of electronic nicotine delivery systems by pregnant women II: Hair biomarkers for exposures to nicotine and tobacco-specific nitrosamines.

INTRODUCTION: Public awareness of electronic nicotine delivery systems (ENDS) has increased over time, and the perception that ENDS offer a safer alternative to cigarettes may lead some pregnant women to use them to reduce cigarette smoking during pregnancy. No previous studies have used metabolite levels in hair to measure nicotine exposure for ENDS users during pregnancy. We aimed to measure and compare levels of nicotine, cotinine, and tobacco-specific nitrosamines (TSNAs) in hair samples from pregnant women who were current ENDS users, current smokers, and current non-smokers. We also aimed to estimate the association between ENDS use/smoking and smallness for gestational age (SGA). METHODS: We used hair specimens from pregnant women who were dual users (ENDS and cigarettes), smokers, and non-smokers from a prospective cohort study to estimate exposure to nicotine, cotinine, and TSNAs. The exposure biomarkers and self-reports of smoking and ENDS use were used in log-binomial regression models to estimate risk ratios (RRs) for SGA among offspring. RESULTS: Nicotine concentrations for pregnant dual users were not significantly different from those for smokers (11.0 and 10.6 ng/mg hair, respectively; p=0.58). Similarly, levels of cotinine, and TSNAs for pregnant dual users were not lower than those for smokers. The RR for SGA was similar for dual users and smokers relative to nonsmokers, (RR=3.5, 95% CI: 0.8-14.8) and (RR=3.3, 95% CI: 0.9-11.6), respectively. Using self-reports confirmed by hair nicotine, the RR values for dual ENDS users and smokers were 8.3 (95% CI: 1.0-69.1) and 7.3 (95% CI:1.0-59.0), respectively. CONCLUSIONS: We did not observe lower levels of nicotine, cotinine, and TSNAs for current dual users compared to smokers during pregnancy. The risk of SGA for offspring of pregnant dual users was similar to that for offspring of pregnant smokers. Future studies are needed to further estimate the magnitude of the association between ENDS use and smallness for gestational age.

Naval Medicine's Involvement in Global Health: The Participation of Women's Healthcare Providers in Continuing Promise 2017.

INTRODUCTION: This is a retrospective review of information collected during operation Continuing Promise 2017 from the Wayuu population in Colombia, South America. MATERIALS AND METHODS: Team objective was to present an overview of women's health care needs in an isolated underserved population of Colombia by a humanitarian mission of health care providers from the U.S. Navy. We analyzed demographics, contraceptive selection, presenting complaint, diagnosis, and disposition of those female patients presenting for care. RESULTS: The acute care clinics of this mission saw patients for 10 full clinic days in each of the countries of Guatemala, Honduras, and Colombia. In the Wayuu clinic of Colombia, 356 patients were seen in the acute care women's clinic. These women averaged 36 years of age with an age range of 9-77 years of age and a gravidity of 3 ± 3.3 and a range of 0-18. Of the women less than the age of 50, not permanently sterilized, 186/220 (84.5%) were not using any form of contraception. The most common chief complaints were vaginal discharge and pelvic pain and the most common final diagnosis was bacterial vaginosis. The two most common secondary diagnoses of the pregnant women were urinary tract infection and anemia. Other significant diagnoses included uterine cancer, preterm labor, and fetal posterior urethral valve syndrome. CONCLUSIONS: A majority of Wayuu women presenting to an acute clinic setting in Colombia, South America were in their mid-thirties having had three pregnancies and the majority were not using any form of contraception. The most common diagnoses were straightforward diagnoses such as vaginal infections, urinary tract infections, and abnormal uterine bleeding. Our findings suggest a need for access to routine gynecologic care, general hygiene education, and increased availability of birth control among the Wayuu population.

Bladder Stone in Pregnancy: A Case Report and Review of the Literature.

BACKGROUND Bladder stones are rare in pregnancy, and can be associated with adverse outcomes such as recurrent urinary tract infection and obstruction of labor. Management of bladder stones discovered in pregnancy has traditionally been done via open techniques such as cystolithotomy or with percutaneous removal. Our objective was to present a case of bladder stone in pregnancy and review prior reports on bladder stones and management in pregnancy. CASE REPORT A 28-year-old gravida 4 para 3 at 10 weeks gestation presented with dysuria, bladder spasm, weak urinary stream, and positional voiding. On first trimester ultrasound, a bladder stone (sized 3.7 cm) was identified and was confirmed by x-ray (KUB). Urology was consulted and removed the stone via cystolitholapaxy with holmium laser. Her symptoms subsequently resolved, and she went on to have an uncomplicated term spontaneous vaginal delivery. The removal of the stone enabled her to have a subsequent vaginal delivery without the potential for obstruction of labor. CONCLUSIONS Based on our review of the literature and this case report, laser cystolitholapaxy is a safe alternative to open surgery for the management of bladder stones in pregnancy. When discovered at the time of delivery, vaginal delivery is feasible if the stone is small or can be displaced. If encountered at time of cesarean delivery, then cystotomy with stone removal is recommended provided inflammation is not present.

The Use of Electronic Cigarettes in Pregnancy: A Review of the Literature.

IMPORTANCE: Electronic cigarette (e-cigarette) use in pregnancy has been steadily increasing and has been hyped as being a safe alternative to cigarette smoking during pregnancy. This review discloses what is currently known about e-cigarette use in pregnancy and the effects of its use on pregnancy outcomes. OBJECTIVE: To determine what is currently known about the prevalence of e-cigarette use in pregnancy and the effects of e-cigarette use on pregnancy and perinatal/neonatal outcomes. EVIDENCE ACQUISITION: A PubMed, CINAHL, and EMBASE search was undertaken using the search terms "pregnancy" OR "pregnancy complications" OR "pregnancy outcome" OR "newborn" OR "neonate" OR "birth" AND "electronic cigarettes" OR "e-cigarettes" OR "ecigarettes" OR "vaping" OR "vape." The search was limited to the English language and between 2007 and October 12, 2017. RESULTS: The search identified 91 articles, 40 of which are the basis for this review. The prevalence of e-cigarette use is 0.6% to 15%. The amount of nicotine consumed by e-cigarette users is comparable to that consumed by cigarette smokers. Most of the animal model studies suggest a potential danger to the developing fetus primarily because of the nicotine consumed and that consumption has multiple effects on the immune system, neural development, lung function, and cardiac function. There is a widespread flawed perception that e-cigarettes are safe to use during pregnancy. CONCLUSIONS: The marketing of e-cigarette use as a safer alternative to cigarette smoking has led to an increasing use even in pregnancy. The nicotine consumed by e-cigarettes is similar to that consumed by cigarette smoking. Animal studies confirm the dangers of nicotine to the developing fetus. More research needs to be done specifically assessing e-cigarette use, pregnancy, and pregnancy outcomes. RELEVANCE: The amount of nicotine consumed in cigarette smoking is similar to the amount of nicotine consumed with e-cigarettes. The effects of nicotine exposure during fetal development are well known and include effects on multiple organ systems.

Uterine Inversion: A Review of a Life-Threatening Obstetrical Emergency.

IMPORTANCE: Uterine inversion is frequently accompanied by postpartum hemorrhage and hypovolemic shock. Morbidity and mortality occur in as many as 41% of cases. Prompt recognition and management are of utmost importance. OBJECTIVE: The aim of this review is to describe risk factors, clinical and radiographic diagnostic criteria, and management of this rare but potentially life-threatening complication of pregnancy. EVIDENCE ACQUISITION: A PubMed, Web of Science, and CINAHL search was undertaken with no limitations on the number of years searched. RESULTS: There were 86 articles identified, with 25 being the basis of review. Multiple risk factors for a uterine inversion have been suggested including a morbidly adherent placenta, short umbilical cord, congenital weakness of the uterine wall or cervix, weakening of the uterine wall at the placental implantation site, fundal implantation of the placenta, uterine tumors, uterine atony, sudden uterine emptying, fetal macrosomia, manual removal of the placenta, inappropriate fundal pressure, excessive cord traction, and the use of uterotonic agents prior to placental removal. The diagnosis is almost exclusively clinical, and successful treatment depends on prompt recognition of the uterine inversion. Treatment options include manual and surgical replacement of the inverted uterus. There is no consensus regarding mode of delivery in subsequent pregnancies as reinversion in a subsequent pregnancy is unpredictable. However, if surgical replacement was required in the index pregnancy and involved an incision into the contractile portion of the uterus, cesarean delivery is a reasonable management option similar to that offered for a prior classic cesarean section. CONCLUSIONS: Successful treatment is dependent on prompt recognition. Management should include resuscitation of maternal hypovolemic shock, as well as repositioning of the inverted uterine fundus. RELEVANCE: Uterine inversion is a rare but potentially life-threatening obstetrical emergency.

Urethral Diverticulum Presenting as a Large Vaginal Mass Complicating Pregnancy and Delivery.

BACKGROUND A case report of urethral diverticulum complicating pregnancy is presented. The diagnosis and management are challenging because of the rare nature of this condition, the varied presentations and differential diagnoses, and the possibility of misdiagnosis. CASE REPORT A 25-year-old primigravida with scheduled induction of labor at 39 weeks gestation due to gestational diabetes mellitus presented for a routine antenatal appointment at 38 weeks and four days. On digital cervical examination, she was found to have a large semi-solid anterior vaginal mass, shown by trans-vaginal ultrasound to have a nearly solid appearance of a 5×7 cm mass with septation. Maternal Fetal Medicine and Gynecologic Oncology consultations were obtained primary cesarean section with vaginal biopsy in the Operating Room were recommended. Following an uncomplicated cesarean delivery and with the patient still under spinal anesthesia, the anterior vaginal mass was examined and found to contain 200 ml of purulent material. Because a diagnosis of urethral diverticulum was made, a biopsy was not performed. The patient was placed on antibiotic prophylaxis for the remainder of her hospital course. Follow-up CT scan confirmed a large urethral diverticulum, and she was referred to the Fetal Pelvic Medicine and Reconstructive Surgery (FPMRS) and Urogynecology units for treatment. CONCLUSIONS Early identification of urethral diverticulum during the pregnancy may allow for treatment and a trial of labor with vaginal delivery. MRI is the recommended imaging modality in identifying urethral diverticulum.

Antenatal corticosteroid treatment: factors other than lung maturation.

Antenatal corticosteroid (CS) therapy improves both fetal lung mechanism and gas exchange due to accelerated morphologic development of type one and two pneumocytes. This therapy also enhances the production of surfactant binding proteins and fetal lung antioxidant enzymes. In women with threatening preterm delivery, a single course is advocated between 24 and 34 weeks' gestation with either betamethasone (two doses of 12 mg 24 h apart) or dexamethasone (four doses of 6 mg at 12-h intervals). Such treatment reduces the rate of respiratory distress syndrome, comorbidity, and mortality in neonates in the first 48 h of life. The optimal time interval between CS administration and delivery is reported to be 1-7 days. Weekly repeat courses reduce the occurrences and severity of respiratory diseases but are associated with reduce fetal growth. Multiple courses should be avoided. However, a repeat course should be considered in women at risk of preterm birth 7 or more days after an initial course in women who remain at risk of preterm birth <34 weeks' gestation. CS may be harmful in growth restricted fetuses associated with an absent or reversed end-diastolic UA flow since they are at increased risk of acidosis and perinatal death. The purpose of this publication is to update and highlight antenatal CS therapy.

Incarceration of the Gravid Uterus.

OBJECTIVE: The aim of this review was to describe the risk factors, clinical and radiographic criteria, and management of this rare complication of pregnancy. METHODS: A PubMed, Web of Science, and CINAHL search was undertaken with no limitations on the number of years searched. RESULTS: There were 60 articles identified, with 53 articles being the basis of this review. Multiple risk factors have been suggested in the literature including retroverted uterus in the first trimester, deep sacral concavity with an overlying sacral promontory, endometriosis, previous abdominal or pelvic surgery, pelvic or uterine adhesions, ovarian cysts, leiomyomas, multifetal gestation, uterine anomalies, uterine prolapse, and uterine incarceration in a prior pregnancy. The diagnosis is difficult to make owing to the nonspecific presenting symptoms. The diagnosis is clinical and confirmed by imaging. Magnetic resonance imaging is superior to ultrasound to accurately diagnose and elucidate the distorted maternal anatomy. Treatment is dictated by gestational age at diagnosis based on risks and benefits. The recommended route of delivery is cesarean delivery when uterine polarity cannot be corrected. CONCLUSIONS: Incarceration of the gravid uterus is a rare but serious complication of pregnancy. The diagnosis is clinical and confirmed with imaging, with magnetic resonance imaging being superior to delineate the distorted maternal anatomy. Reduction of the incarcerated uterus should be attempted to restore polarity and avoid unnecessary cesarean delivery.

Application of a Telecolposcopy Program in Rural Settings.

BACKGROUND: Individuals in rural areas are often restricted by the amount of physicians' availability, thus limiting access to healthcare in those settings. INTRODUCTION: While Pap smear screening has increased across the United States, the rural South still reports high rates of cervical cancer and mortality. One solution to improve patient outcomes related to cervical cancer in rural settings is telecolposcopy. MATERIALS AND METHODS: Women with abnormal Pap results or an abnormal visual examination needing an evaluation by colposcopy were referred to a hospital-based telecolposcopy program. Descriptive data are provided that include patients' access to care based on travel time and transportation costs. RESULTS: Over a 15-month time period, 940 unique patients were seen using telecolposcopy. Telecolposcopy was done at eight spoke sites across Arkansas representing patients from 72 of the 75 counties. Data for risk factors that include smoking, first sexual experience, and number of sexual partners in past 12 months and in a lifetime are discussed. Pap results and impression are provided. In addition, avoided transportation costs and travel time have been calculated and included. DISCUSSION: Cervical cancer is important public health concern especially for women residing in rural areas. We were able to demonstrate that our telecolposcopy program has provided sustainability statewide since its inception and that patients are willing to participate. In addition to providing increased access to care, the program also reduced travel time and costs associated with a face-to-face visit. CONCLUSION: Telecolposcopy should be further explored and utilized in rural settings as a way to reduce patient costs and improve cervical cancer outcomes.

Idiopathic polyhydramnios: persistence across gestation and impact on pregnancy outcomes.

PURPOSE: To investigate the likelihood of resolution of idiopathic polyhydramnios in pregnant women and compare outcomes between resolved and persistent cases. METHODS: One hundred and sixty-three women with idiopathic polyhydramnios who delivered at two medical centers during a 3 year period (January 2012-January 2015) were included in the study. Exclusion criteria included congenital fetal anomalies, maternal diabetes, isoimmunization, fetal infection, placental tumors or anomalies, and multiple gestation. Polyhydramnios was defined as SDP≥8cm or AFI≥24cm. Resolved cases were defined as those with AFI and/or SDP falling and remaining below 24cm and 8cm respectively. Pregnancy outcomes were compared between resolved and persistent cases. Two-sample t-test or Wilcoxon rank-sum test was used for continuous variables while chi-square test or Fisher's exact test was used for categorical measures. RESULTS: Resolution was noted in 61 of 163 (37%) patients. There were no differences in maternal age, gravidity or parity between resolved and persistent cases. Mean gestational age at diagnosis of polyhydramnios and overall mean AFI were significantly lower in the cases that resolved (29.7±4.5 weeks vs 33.4±4.1 weeks, p<0.0001; 23.3±3.5cm vs 25.8 23.3±4.0cm, p=0.0002). Similar to AFI measurements, mean SDP was also lower in cases with resolution (p=0.002). There was no difference in induction rates, mode of delivery, amnioinfusion rates, meconium staining of amniotic fluid and fetal heart rate abnormalities influencing intrapartum management between the two groups. Induction of labor for fetal indication and rupture of membranes were significantly more common in the persistent group. Cesarean delivery for abnormal lie and fetal distress did not differ between the groups. There was an increased risk of macrosomia (>4000g) and preterm delivery (<37 weeks) in the persistent group (p<0.05). CONCLUSIONS: Resolution rate was approximately 37% and more likely in cases diagnosed earlier in pregnancy and with lower mean amniotic fluid volume. Preterm delivery and macrosomia were more common in cases that persisted across gestation.

Patient Awareness of Untoward Effects of Smoking on Fetal and Maternal Well-being During Pregnancy: A Pilot Study.

INTRODUCTION: To identify knowledge gaps regarding adverse effects of smoking during pregnancy that could be targeted through antenatal education. METHODS: This was a cross-sectional survey of patients who presented for initial prenatal care from April 6, 2011, through May 25, 2011. Inclusion criteria included fluency in English and completion of at least 75% of the questionnaire. Survey included demographic information and 4 sections that assessed (1) general knowledge about the effects of smoking, (2) cancer risks associated with smoking, (3) maternal and fetal complications resulting from smoking, and (4) long-term effects of smoking on offspring. Participants were grouped as nonsmokers, former smokers, and current smokers. Data from each group were compared using analysis of variance with Tukey-Kramer post-hoc tests. RESULTS: There were 82 participants (54 nonsmokers, 17 former smokers, and 11 smokers). Self-perceived knowledge about the adverse effects of smoking was significantly less in smokers than in nonsmokers (P < 0.05). There was no statistical difference between the knowledge base of smokers when compared with nonsmokers and former smokers. Smokers seemed to be less aware of the long-term respiratory morbidity associated with maternal smoking in their offspring. There was an overall deficit in knowledge among all 3 groups of cancer risks associated with smoking other than lung cancer. CONCLUSIONS: Obstetrician-gynecologists should employ more aggressive approaches in the education of pregnant parturients about the known deleterious maternal and fetal effects of smoking, especially those risks related to cancers other than lung and long-term respiratory morbidity in their children.

Screening for intrauterine growth restriction in uncomplicated pregnancies: time for action.

A randomized clinical trial (RCT) noted that sonographic examination in the third trimester, in conjunction with delivery at term for abnormalities of fetal growth, significantly decreased the likelihood of small-for-gestational-age (SGA) neonates in uncomplicated pregnancies. We identified 15 characteristics of screening tests and attempted to determine if there is evidence to routinely obtain sonographic estimates of fetal weight in the third trimester and decrease rates of SGA. Of the 15 suggested characteristics, currently 10 (67%) are fulfilled, two are uncertain (sonographic examination is cost-effective or reliable), and one (the test must do its job) is possibly valid. Due to the lack of RCTs demonstrating reduction in morbidity, there is potential for lead-time and length bias. To observe a 36% decrease (from 4.1 to 2.6%) decrease in composite perinatal morbidity, 6000 women need to be randomized to at least two sonographic examinations in the third trimester versus routine prenatal care. Such an RCT is warranted and justified.
