The SunBEAm birth cohort: Protocol design.

Background: Food allergy (FA) and atopic dermatitis (AD) are common conditions that often present in the first year of life. Identification of underlying mechanisms and environmental determinants of FA and AD is essential to develop and implement effective prevention and treatment strategies. Objectives: We sought to describe the design of the Systems Biology of Early Atopy (SunBEAm) birth cohort. Methods: Funded by the National Institute of Allergy and Infectious Diseases (NIAID) and administered through the Consortium for Food Allergy Research (CoFAR), SunBEAm is a US population-based, multicenter birth cohort that enrolls pregnant mothers, fathers, and their newborns and follows them to 3 years. Questionnaire and biosampling strategies were developed to apply a systems biology approach to identify environmental, immunologic, and multiomic determinants of AD, FA, and other allergic outcomes. Results: Enrollment is currently underway. On the basis of an estimated FA prevalence of 6%, the enrollment goal is 2500 infants. AD is defined on the basis of questionnaire and assessment, and FA is defined by an algorithm combining history and testing. Although any FA will be recorded, we focus on the diagnosis of egg, milk, and peanut at 5 months, adding wheat, soy, cashew, hazelnut, walnut, codfish, shrimp, and sesame starting at 12 months. Sampling includes blood, hair, stool, dust, water, tape strips, skin swabs, nasal secretions, nasal swabs, saliva, urine, functional aspects of the skin, and maternal breast milk and vaginal swabs. Conclusions: The SunBEAm birth cohort will provide a rich repository of data and specimens to interrogate mechanisms and determinants of early allergic outcomes, with an emphasis on FA, AD, and systems biology.

Pelvic Girdle Pain in Pregnancy: A Review.

Importance: Pelvic girdle pain is often thought to be a recent phenomenon, but this condition was described as early as 400 BC by Hippocrates. Despite being identified for years, confusion continues about the definition and management of this ailment affecting many pregnancies. Objective: The purpose of the review is to assess the incidence, etiology, pathophysiology, risk factors, diagnosis, management, and pregnancy outcomes/recovery of current pregnancies, and outcomes of future pregnancies complicated by pelvic girdle pain. Evidence Acquisition: Electronic databases (PubMed and Embase) were searched from 1980 to 2021 with the only limitation being that the articles were in English. Studies were selected that examined associations between pelvic pain/pelvic girdle pain and pregnancy. Results: There were 343 articles identified. After reviewing the abstracts, 88 were used in this review. Pelvic girdle pain is a common condition of pregnancy, affecting a reported 20% of pregnant women. The pathophysiology is poorly understood and likely multifactorial, involving both hormonal and biomechanical changes that occur during pregnancy. Several risk factors have been identified. This diagnosis is most commonly made based on symptoms related to pelvic pain during pregnancy. Treatment should be multimodal, including pelvic girdle support, stabilizing exercises, analgesia, and potentially complementary therapies. The effects on future pregnancies are uncertain, although some limited information suggests an increased risk of recurrent PGP in subsequent pregnancies. Conclusions: Pelvic girdle pain in pregnancy is a common condition that is often overlooked as a normal part of pregnancy but has a significant impact on quality of life during, after, and in subsequent pregnancies. Multimodal therapies are available and are largely low cost and noninvasive. Relevance: Our aim is to increase the awareness of pelvic girdle pain in pregnancy as a common but often underdiagnosed and undertreated condition.

Exploring the feasibility, acceptability, and preliminary effectiveness of a culturally adapted group prenatal program, CenteringPregnancy, to reduce maternal and infant health disparities among Marshallese Pacific Islanders: A study protocol.

Background: Marshallese Pacific Islanders residing in the United States have higher rates of adverse perinatal outcomes than the general population and experience numerous barriers to prenatal care. CenteringPregnancy is a group prenatal care model which occurs in the patient's community. CenteringPregnancy, when applied to the Marshallese population, presents a potentially highly successful group-based intervention that can mitigate adverse perinatal outcomes among Marshallese Pacific Islanders. Methods: This article describes the protocol of a mixed-methods study designed to examine the feasibility, acceptability, and preliminary effectiveness of the implementation of CenteringPregnancy for Marshallese Pacific Islander women. The mixed-methods design collects qualitative and quantitative data at the onset of CenteringPregnancy and during their last session and then augments the data with post-partum data abstraction. Conclusion: This will be the first study to culturally adapt and implement CenteringPregnancy with Marshallese pregnant women in the United States. This study will be an important first step to exploring the feasibility, acceptability, and preliminary effectiveness of CenteringPregnancy and will better prepare the research team to assess and refine the intervention moving forward. Trial registration: This study was registered at ClinicalTrials.gov on September 22, 2020 under identifier NCT04558619 and can be accessed at https://clinicaltrials.gov/ct2/show/NCT04558619?term=K%C5%8Dmmour+Prenatal&draw=2&rank=1.

Marshallese Mothers' and Marshallese Maternal Healthcare Providers' Perspectives on Contraceptive Use and Reproductive Life Planning Practices and Influences.

Pacific Islander communities experience significant maternal and infant health disparities including high maternal and infant mortality. Contraception and reproductive life planning prevent approximately one-third of pregnancy-related deaths and neonatal deaths. We report the results of formative research devoted to understanding Marshallese mothers' as well as their maternal healthcare providers' practices and influences related to contraceptive use and reproductive life planning. This study used an exploratory, descriptive qualitative design to explore Marshallese mothers' and maternal healthcare providers' practices and influences of contraception use and reproductive life planning. Twenty participants were enrolled in the study, 15 Marshallese mothers and five Marshallese maternal healthcare providers. For the Marshallese mothers, two themes emerged: (1) Reproductive Life Planning Practices and Information; and (2) Reproductive Life Planning Influences. For the Marshallese maternal healthcare providers, two themes emerged: (1) Reproductive Life Planning Practices; and (2) Reproductive Life Planning Influences. This is the first study to document Marshallese mothers' and maternal healthcare providers' practices and influences with contraceptive use and reproductive life planning. Study results will inform the development of a culturally-adapted contraception and reproductive life planning tool with an educational program for Marshallese family units and maternal healthcare providers serving Marshallese women.

Title: Is Mild Idiopathic Polyhydramnios Associated with an Increased Risk for an Intrauterine Fetal Demise? A Retrospective Cohort Study.

Objective: Antenatal fetal surveillance has been recommended for moderate/severe idiopathic polyhydramnios but not for mild idiopathic polyhydramnios. The purpose of this study is to determine if pregnancies with mild idiopathic polyhydramnios have an increased risk for an intrauterine fetal demise (IUFD). Methods: Medical records and amniotic fluid volume ultrasound data from 2016 to 2021 at a university medical center were examined. Pregnancies with fetal anomalies, fetal infection, isoimmunization, multiple gestation, maternal diabetes and oligohydramnios were excluded. Normal amniotic fluid volume was defined as an amniotic fluid index (AFI) <24 cm which was compared to mild idiopathic polyhydramnios, AFI of ≥24.0 cm-29.9 cm, and moderate/severe polyhydramnios which is an AFI ≥30 cm. Results: Of 12,725 patients meeting inclusion study criteria, there were 249 with idiopathic polyhydramnios (n = 249) which was associated with an increased odds of IUFD (aOR) of 3.27 (CI 1.50-7.15), NICU admission (aOR 1.28, CI 0.96-1.70), 5-minute APGAR score less than 7 (aOR 2.16, CI 1.52-3.07), and large for gestational age infant (LGA) (aOR 4.04, CI 2.83-5.78) compared to normal amniotic fluid volume (AFV). In the mild polyhydramnios group (n = 204, out of the 249 women with polyhydramnios) compared to the 12,476 pregnancies with normal AFV group, IUFD (aOR 3.38, CI 1.46-7.82), NICU admission (aOR 1.19, CI 0.87-1.64), 5-minute APGAR score less than 7 (aOR 1.68, CI 1.10-2.55) and LGA (aOR 3.87, CI 2.59-5.78). In moderate/severe polyhydramnios group (n = 45) compared to the normal AFV group, there was no increased odds of IUFD (aOR 2.78, CI 0.38-20.29) or NICU admission (aOR 1.74, CI 0.93-3.26) but an increased odds for a 5-minute APGAR score less than 7 (aOR 4.94, CI 2.57-9.53) and LGA fetus (aOR 4.80, CI 2.26-10.22). Conclusion: There is an increased odds of IUFD in pregnancies complicated by mild idiopathic polyhydramnios. Patients should be counseled on an increased odds of adverse pregnancy outcomes associated with idiopathic polyhydramnios, and in those pregnancies with mild idiopathic polyhydramnios, antenatal fetal surveillance should be considered.

Racial and ethnic disparities in access to gynecologic care.

PURPOSE OF REVIEW: Despite efforts to minimize patient barriers to equitable care, health disparities persist in gynecology. This paper seeks to highlight racial and ethnic disparities in gynecologic care as represented by recent literature. RECENT FINDINGS: Disparities exist among many areas including preventive screenings, vaccination rates, contraception use, infertility, and oncologic care. These can be identified at the patient, physician, and institutional levels. SUMMARY: As we identify these social disparities in healthcare, we gain valuable knowledge of where our efforts are lacking and where we can further improve the health of women. Future research should focus on identifying and combating such disparities with measurable changes in health 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.

Umbilical Cord Prolapse: A Review of the Literature.

IMPORTANCE: Umbilical cord prolapse is a rare occurrence and is a life-threatening emergency for the fetus. These events are unpredictable and unpreventable. Umbilical cord prolapse requires swift diagnosis and management for optimal outcome. OBJECTIVE: The aim of this review is to describe the incidence, risk factor, pathophysiology, diagnosis, and management of this rare but potentially life-threatening event. EVIDENCE ACQUISITION: A PubMed, Web of Science, and CINAHL search was undertaken with no limitations on the number of years searched. RESULTS: There were 200 articles identified, with 53 being the basis of review. Multiple risk factors for a umbilical cord prolapse have been suggested including fetal malpresentation or abnormal lie, prematurity, multifetal gestation, and polyhydramnios. The diagnosis is largely made by examination and found after rupture of membranes, and most often, examination is prompted by fetal heart rate decelerations. The management of umbilical cord prolapse is expedited delivery; however, there are rare specific scenarios in which immediate delivery is not possible and efforts should be made to relieve cord compression. CONCLUSIONS: Rapid identification of an umbilical cord prolapse facilitates management and increases likelihood of an optimal outcome. The management is an expedited delivery with efforts to relieve cord compression until delivery can be achieved. RELEVANCE: Umbilical cord prolapse is a rare but a life-threatening obstetrical emergency.

Intra-Amniotic Hemorrhage Imitating Gastroschisis: A Case Report and Review of the Literature.

BACKGROUND A spontaneous intra-amniotic hemorrhage is rarely encountered during pregnancy. The correct diagnosis and management are problematic because of the infrequency of this condition and the high likelihood of a misdiagnosis. CASE REPORT A primigravida with an uncomplicated pregnancy and a normal targeted ultrasound presented late in the second trimester of pregnancy with antepartum bleeding of unknown origin. A repeat ultrasound was suggestive of an abdominal wall defect (gastroschisis). The patient continued to have antepartum bleeding and developed uterine contractions and abdominal pain necessitating frequent visits to labor and delivery. An MRI ruled out gastroschisis and diagnosed intra-amniotic hematoma. The patient presented with acute abdominal pain and was clinically considered to be having an abruption, and was delivered by cesarean. Old blood was noted in the abdominal cavity and within the uterine cavity. At the time of the cesarean, an area of intra-amniotic hematoma was identified, as well as a retroplacental blood clot. CONCLUSIONS An intra-amniotic hematoma is unusual and may be misdiagnosed. MRI may be helpful in determining the correct diagnosis and subsequent management.

A phase I dose-escalation clinical trial of a peptide-based human papillomavirus therapeutic vaccine with Candida skin test reagent as a novel vaccine adjuvant for treating women with biopsy-proven cervical intraepithelial neoplasia 2/3.

PURPOSE: Non-surgical treatments for cervical intraepithelial neoplasia 2/3 (CIN2/3) are needed as surgical treatments have been shown to double preterm delivery rate. The goal of this study was to demonstrate safety of a human papillomavirus (HPV) therapeutic vaccine called PepCan, which consists of four current good-manufacturing production-grade peptides covering the HPV type 16 E6 protein and Candida skin test reagent as a novel adjuvant. PATIENTS AND METHODS: The study was a single-arm, single-institution, dose-escalation phase I clinical trial, and the patients (n = 24) were women with biopsy-proven CIN2/3. Four injections were administered intradermally every 3 weeks in limbs. Loop electrical excision procedure (LEEP) was performed 12 weeks after the last injection for treatment and histological analysis. Six subjects each were enrolled (50, 100, 250, and 500 µg per peptide). RESULTS: The most common adverse events (AEs) were injection site reactions, and none of the patients experienced dose-limiting toxicities. The best histological response was seen at the 50 µg dose level with a regression rate of 83% (n = 6), and the overall rate was 52% (n = 23). Vaccine-induced immune responses to E6 were detected in 65% of recipients (significantly in 43%). Systemic T-helper type 1 (Th1) cells were significantly increased after four vaccinations (P = 0.02). CONCLUSION: This study demonstrated that PepCan is safe. A significantly increased systemic level of Th1 cells suggests that Candida, which induces interleukin-12 (IL-12) in vitro, may have a Th1 promoting effect. A phase II clinical trial to assess the full effect of this vaccine is warranted.

Optimizing appointment template and number of staff of an OB/GYN clinic--micro and macro simulation analyses.

BACKGROUND: The Department of Obstetrics and Gynecology (OB/GYN) at the University of Arkansas for Medical Sciences (UAMS) tested various, new system-restructuring ideas such as varying number of different types of nurses to reduce patient wait times for its outpatient clinic, often with little or no effect on waiting time. Witnessing little progress despite these time-intensive interventions, we sought an alternative way to intervene the clinic without affecting the normal clinic operations. AIM: The aim is to identify the optimal (1) time duration between appointments and (2) number of nurses to reduce wait time of patients in the clinic. METHODS: We developed a discrete-event computer simulation model for the OB/GYN clinic. By using the patient tracker (PT) data, appropriate probability distributions of service times of staff were fitted to model different variability in staff service times. These distributions were used to fine-tune the simulation model. We then validated the model by comparing the simulated wait times with the actual wait times calculated from the PT data. The validated model was then used to carry out "what-if" analyses. RESULTS: The best scenario yielded 16 min between morning appointments, 19 min between afternoon appointments, and addition of one medical assistant. Besides removing all peak wait times and bottlenecks around noon and late in the afternoon, the best scenario yielded 39.84 % (p<.001), 30.31 % (p<.001), and 15.12 % (p<.001) improvement in patients' average wait times for providers in the exam rooms, average total wait time at various locations and average total spent time in the clinic, respectively. This is achieved without any compromise in the utilization of the staff and in serving all patients by 5 pm. CONCLUSIONS: A discrete-event simulation model is developed, validated, and used to carry out "what-if" scenarios to identify the optimal time between appointments and number of nurses. Using the model, we achieved a significant improvement in wait time of patients in the clinic, which the clinic management initially had difficulty achieving through manual interventions. The model provides a tool for the clinic management to test new ideas to improve the performance of other UAMS OB/GYN clinics.

Role of telephone triage in obstetrics.

UNLABELLED: The telephone has become an indispensable method of communication in the practice of obstetrics. The telephone is one of the primary methods by which the patient makes her appointments and contacts her health care provider for advice, reassurance, and referrals. Current methods of telephone triage include personal at the physicians' office, telephone answering services, labor and delivery nurses, and a dedicated telephone triage system using algorithms. Limitations of telephone triage include the inability of the provider to see the patient and receive visual clues from the interaction and the challenges of obtaining a complete history over the telephone. In addition, there are potential safety and legal issues with telephone triage. To date, there is insufficient evidence to either validate or refute the use of a dedicated telephone triage system compared with a traditional system using an answering service or nurses on labor and delivery. TARGET AUDIENCE: Obstetricians and gynecologists, family physicians. LEARNING OBJECTIVES: After completing this CME activity, physicians should be better able to analyze the scope of variation in telephone triage across health care providers and categorize the components that go into a successful triage system, assess the current scope of research in telephone triage in obstetrics, evaluate potential safety and legal issues with telephone triage in obstetrics, and identify issues that should be addressed in any institution that is using or implementing a system of telephone triage in obstetrics.

Neurodevelopmental changes of fetal pain.

Pain in the developing fetus is controversial because of the difficulty in measuring and interpreting pain during gestation. It has received increased attention lately because of recently introduced legislation that would require consideration of fetal pain during intentional termination of pregnancy. During development, sensory fibers are abundant by 20 weeks; a functional spinal reflex is present by 19 weeks; connections to the thalamus are present by 20 weeks; and connections to subplate neurons are present by 17 weeks with intensive differentiation by 25 weeks. These cells are important developmentally, but decline as a result of natural apoptosis. Mature thalamocortical projections are not present until 29 to 30 weeks, which has led many to believe the fetus does not experience emotional "pain" until then. Pain requires both nociception and emotional reaction or interpretation. Nociception causes physiologic stress, which in turn causes increases in catecholamines, cortisol, and other stress hormones. Physiological stress is different from the emotional pain felt by the more mature fetus or infant, and this stress is mitigated by pain medication such as opiates. The plasticity of the developing brain makes it vulnerable to the stressors that cause long-term developmental changes, ultimately leading to adverse neurological outcomes. Whereas evidence for conscious pain perception is indirect, evidence for the subconscious incorporation of pain into neurological development and plasticity is incontrovertible. Scientific data, not religious or political conviction, should guide the desperately needed research in this field. In the meantime, it seems prudent to avoid pain during gestation.
