Amniotic fluid volume and pregnancy outcomes in twin pregnancies: A systematic review and meta-analysis.

Objective: To analyse amniotic fluid volume (AFV), specifically oligohydramnios or polyhydramnios, and associated pregnancy and neonatal outcomes in twin gestations through systematic review and meta-analysis. Methods: We utilised systematic review methodology to identify items within published and grey literature resources. Prospective and retrospective studies with a control group were included. Inclusion criteria were as follows: studies in English, twin pregnancy in which AFVs and associated pregnancy and/or neonatal outcomes were evaluated. Exclusion criteria included the presence of an anomalous fetus, chromosome abnormality, monochorionic diamniotic twin pregnancy complicated by twin-twin transfusion syndrome or twin-reversed arterial perfusion, twin gestations undergoing therapeutic interventions (i.e. fetoscopic laser photocoagulation and serial amniocentesis) and monochorionic monoamniotic twin pregnancy. Results: The literature search identified 1068 abstracts, only four met criteria for inclusion and analysis. The pooled data (two studies per outcome) revealed no significant difference in rate of pre-term delivery (OR: 2.94; CI: 0.20-43.81), pre-term delivery less than 32 weeks (OR: 1.97; CI: 0.43-9.12), umbilical cord pH < 7 (OR: 2.66; CI: 0.22-32.51), rate of stillbirth (OR: 4.13; CI: 0.40-42.70), neonatal death (OR: 1.48; CI: 0.05-43.94), rate of NICU admission (OR: 1.38; CI: 0.61-3.11) or rate of small-for-gestational-age (SGA) infants (OR: 1.39; CI: 0.33-5.94). Conclusion: Based on the pooled data (two studies per outcome), there was no difference in the fate of pre-term delivery, umbilical cord pH < 7, stillbirth, neonatal death or SGA infants. What is disturbing is the lack of studies (1946-2020) that analysed the association between AFV and pregnancy outcomes in twin pregnancies.

Examination of a Stillbirth Workup: A Rural Statewide Experience.

OBJECTIVE: The objective of our study was to determine whether recommended assessments were conducted on stillbirths delivered in our predominantly rural state. METHODS: This was a descriptive study of stillbirths delivered in a rural state and included in one site of the Birth Defects Study to Evaluate Pregnancy Exposures stillbirth study. Hospital and fetal death records were examined to determine whether the following areas were evaluated: genetic testing (noninvasive perinatal testing, quad screen, amniocentesis/chorionic villus sampling with karyotype, microarrays, fetal tissue specimen), placenta/membrane/cord sent for pathologic examination, examination of the stillbirth after delivery by the healthcare provider, and fetal autopsy was performed. RESULTS: From July 1, 2015 to June 30, 2020, there were 1108 stillbirths delivered in Arkansas. The most frequent assessments undertaken were placental pathology (72%), genetic testing (67%), fetal inspection (31%), and autopsy (13%). All four assessments were done in 2% of stillbirth cases, three assessments in 27%, two assessments in 47%, one assessment in 14%, and no assessment in 15%. There was no association between stillbirth assessment evaluation by gestational age (<28 weeks and > 28 weeks; P = 0.221); however, there was an overall association between hospital delivery volume with number of components completed (P < 0.0001). Hospitals with >2000 deliveries had a higher proportion of three or four completions compared with those hospitals with <1000 deliveries or 1000 to 2000 deliveries (P = 0.021 and P < 0.0001). CONCLUSIONS: Fetal stillbirth assessment is suboptimal in our rural state, with 15% of stillbirths having no assessment and only 2% having all four assessments. There is no association between stillbirth assessment and gestational age (<28 weeks vs >28 weeks), but there is a correlation between delivery volume and stillbirth assessment.

July Effect in Obstetric Outcomes.

OBJECTIVE: The July effect represents the month when interns begin residency and residents advance with increased responsibility. This has not been well studied in Obstetrics and Gynecology residencies and no study has been conducted evaluating obstetric outcomes. The purpose of this study was to evaluate the July effect on obstetric outcomes. Women who delivered between July and September (quarter 1) were compared to those delivering between April and June (quarter 4). METHODS: This retrospective cohort study compared outcomes of deliveries between quarter 1 and quarter 4 from 2017 to 2020. Outcomes evaluated were postpartum length of stay (LOS), postpartum readmission, wound complication, wound infection, blood transfusion, estimated blood loss, 3rd and 4th degree lacerations, 5 min APGAR scores, and cesarean delivery rates. RESULTS: There were 3693 deliveries in quarter 1 and 3107 deliveries in quarter 4. There was a higher incidence Of wound infection during the April-June period (N = 21; 0.68%) compared to July-September (N = 10; 0.27%; p = 0.0135). Although LOS for both periods were the same, the average postpartum LOS during July-September was slightly longer than April-June (1.7 days; SD = 1.1 vs 1.6 days; SD = 1.2; p = 0.0026). All other pregnancy outcomes were similar between the two groups. CONCLUSION: Overall, the July effect is minimal on obstetric complications. However, LOS between July and September may differ because all residents are less experienced in quarter 1. Wound infection rates were higher in April-June, perhaps because new PGY-1s went from assisting to primary on cesarean surgeries starting in the 4th quarter of the year.

Hyperparathyroidism in Pregnancy: A Review of the Literature.

IMPORTANCE: Maternal hyperparathyroidism can be associated with significant maternal and fetal morbidity and fetal mortality. Because the maternal symptoms are typically nonspecific, the disorder may not be recognized leading to adverse pregnancy outcomes. OBJECTIVE: The aim of this study was to review the literature on the etiology/prevalence, pathophysiology, diagnosis, management (medical and surgical), and the maternal/neonatal complications associated with pregnancies complicated by hyperparathyroidism. EVIDENCE ACQUISITION: A literature search was undertaken by our university librarian using the search engines PubMed and Web of Science. Search terms used included "hyperparathyroidism" AND "pregnancy" OR "pregnancy complications" OR "maternal." The number of years searched was not limited, but the abstracts had to be in English. RESULTS: There were 309 abstracts identified, 164 of which are the basis of this review. This includes 137 articles of the 269 individual case reports in the literature since the first case report in 1947. The articles and case reports reviewed the etiology, risk factors, diagnosis, management, complications, and maternal/fetal outcomes of pregnancies complicated by hyperparathyroidism. CONCLUSIONS AND RELEVANCE: Undiagnosed maternal hyperparathyroidism can result in critical maternal and fetal outcomes during pregnancy. This review highlights what is currently known about hyperparathyroidism during pregnancy to increase the awareness of this serious pregnancy disorder.

Management of Critically Ill Pregnant Patients with COVID-19 Infection in a Rural State.

OBJECTIVE: There is limited data on the treatment of coronavirus disease 2019 (COVID-19) in pregnancy. Arkansas saw an increase in COVID-19 cases in June 2020. The first critically ill pregnant patient was admitted to our institution on May 21st, 2020. The objective of this study was to evaluate outcomes in critically ill pregnant women with COVID-19 at a single tertiary care center who received remdesivir and convalescent plasma (CCP). STUDY DESIGN: This is a retrospective observational review of critically ill pregnant women with COVID-19 who received remdesivir and CCP. This study was approved by the institutional review board (#261354). RESULTS: Seven pregnant patients with COVID-19 were admitted to the intensive care unit (ICU). All received remdesivir and CCP. Six received dexamethasone. The median ICU length of stay (LOS) was 8 days (range 3-17). Patient 1 had multi-organ failure requiring vasopressors, renal dialysis, and had an intrauterine fetal demise. Patients 4 and 6 required mechanical ventilation, were delivered for respiratory distress and were extubated at 2 and 1 days postpartum, respectively. The only common risk factor was obesity. There were no adverse events noted with remdesivir or CCP. CONCLUSION: There is little data regarding the use of remdesivir or CCP for the treatment of COVID-19 in pregnant women. In our cohort, these were well tolerated with no adverse events. Previously reported median ICU LOS in critically ill pregnant women with COVID-19 was 8 days (range 4-15).1 Our study found a similar ICU LOS (8 days; range 3-17). Patient 1 did not receive remdesivir or CCP until transport to our facility on hospital day 3. Excluding patient 1, median ICU LOS was 6.5 days (range 3-9). Our institution's treatment of pregnant women with critical illness with remdesivir, CCP and dexamethasone combined with delivery in select cases has thus far had good outcomes. KEY POINTS: · Combined therapy: remdesivir, CCP, dexamethasone.. · Remdesivir, CCP and dexamethasone was effective in treating critically ill pregnant women with COVID-19.. · No adverse events were associated with combined therapy.. · Delivery improved respiratory status..

Preconception, Antepartum, and Peripartum Care for the Woman With a Spinal Cord Injury: A Review of the Literature.

IMPORTANCE: Spinal cord injury (SCI) may result in temporary or permanent loss of sensory, motor, and autonomic function, presenting unique medical and psychosocial challenges in women during their childbearing years. OBJECTIVE: The aim of this study was to review the literature and describe the spectrum of pregnancy considerations, complications, and evidence-based obstetric practices in women with SCI. EVIDENCE ACQUISITION: A literature search was undertaken using the search engines of PubMed and Web of Science using the terms "spinal cord injury" or "spinal cord complications" and "pregnancy outcomes" or "pregnancy complications." The search was limited to the English language, and there was no restriction on the years searched. RESULTS: The search identified 174 abstracts, 50 of which are the basis for this review. Pregnancy in women who have experienced an SCI requires a multidisciplinary approach. Common complications during pregnancy include recurrent urinary tract infection, upper respiratory tract infection, hypertension, venous thromboembolism, and autonomic dysreflexia (AD), which is a potentially life-threatening complication. Obstetricians should avoid potential triggers and be familiar with acute management of AD. Postpartum complications include difficulty initiating and maintaining breastfeeding and increased risk of postpartum depression and other mental health issues. CONCLUSIONS AND RELEVANCE: Obstetricians caring for women with an SCI must be familiar with the unique challenges and complications that may occur during pregnancy and puerperium. RELEVANCE STATEMENT: An evidence-based literature review of the care of pregnant women with spinal cord injury.

Evidence for Prophylactic Transfusion during Pregnancy for Women with Sickle Cell Disease.

The objective of this study was to examine prior studies on maternal and neonatal outcomes with prophylactic compared with emergent blood transfusion in pregnant women with sickle cell disease. A review of the literature was performed. Twenty-one articles were identified and included in the analysis. A generalized linear mixed-effects model was used to analyze the outcomes. Pregnancy outcomes assessed were preeclampsia, pneumonia, pyelonephritis, pain crises, intrauterine growth restriction, neonatal death, perinatal death, and maternal mortality. Women who underwent emergent transfusion were more likely than women who underwent prophylactic transfusion to have the following adverse perinatal outcomes: preterm delivery (adjusted odds ratio [aOR 2.04], 95% confidence interval [CI] 1.14-3.63), pneumonia (aOR 2.98, 95% CI 1.44-6.15), pain crises (aOR 1.67, 95% CI 1.18-2.38), and perinatal death (aOR 1.84, 95% CI 1.06-3.07). Prophylactic transfusion should be reexamined as a potentially beneficial approach to the management of sickle cell disease in pregnancy.

Torsion in the Gravid and Nongravid Uterus: A Review of the Literature of an Uncommon Diagnosis.

IMPORTANCE: Uterine torsion is an uncommon but life-threatening clinical situation that requires a high index of suspicion for diagnosis. OBJECTIVE: The aim of this study was to review literature and determine the etiology, presentation, diagnosis, and management of uterine torsion in the gravid and nongravid patients. EVIDENCE ACQUISITION: A literature search was undertaken by our research librarian using the search engines PubMed and CINAHL. The search terms used were "uterine torsion" OR (uterus and torsion). The search was limited to the English language, but the years searched were unlimited. RESULTS: The search identified 177 articles, 91 of which are the basis for this review. There have been 41 cases or gravid uterine torsion, their characteristics, and symptoms published since 2006. Torsion is rare in nongravid patients, but can still occur. CONCLUSION AND RELEVANCE: Uterine torsion is rare, can affect all ages, and can have significant implications for women. Prompt recognition allows for timely intervention and can mitigate harm.

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.

Surrogacy and Pregnancy.

IMPORTANCE: Surrogacy allows for parenthood when it is otherwise impossible or exceedingly difficult; however, the risks of surrogate pregnancy for the gestational surrogate and the fetus are not well defined. OBJECTIVE: The aim of this study was to review the literature to examine the prevalence and requirements of surrogate pregnancy and maternal and perinatal outcomes. EVIDENCE ACQUISITION: A CINAHL and 2 PubMed searches were undertaken using the terms "surrogate mothers" OR "(surrogate or surrogacy)" AND "(mothers OR pregnancy OR pregnant)." The second search used these terms and pregnancy outcomes. The search was limited to the English language, but the years searched were unlimited. RESULTS: The search identified 153 articles, 36 of which are the basis for this review. The number of surrogate pregnancies is increasing in the United States. Fetal risks associated with surrogacy include low birth weight, increased risk of multiple gestation, and preterm birth. Maternal complications associated with surrogate pregnancy include hypertensive disorders of pregnancy, postpartum hemorrhage, and gestational diabetes. CONCLUSIONS AND RELEVANCE: Surrogacy is a route to parenting that is not without risk to the surrogate or the fetus, and surrogate pregnancy is increasing in frequency in the United States.
