OBJECTIVE: To evaluate knowledge of Pap smear screening and colposcopy among Appalachian women. MATERIALS AND METHODS: English-speaking women (18 years or older) referred for colposcopy after abnormal Pap testing at a teaching hospital in the southeastern United States were studied. Structured interviews were conducted to assess demographic characteristics, health literacy skills using the Rapid Estimate of Adult Literacy in Medicine, understanding of the Pap smear and colposcopy, state anxiety, and cervical intraepithelial neoplasia distress. RESULTS: The mean age of women was 29.6 +/- 10.94, 93.2% white, 50.2% high school graduates or had an equivalency diploma, and 55.3% current cigarette use. Approximately one fifth (n = 22) of women had limited health literacy skills. Overall, womens' understanding of the Pap test, meaning of abnormal Pap test results, identification of risk factors contributing to abnormal Pap test results, and understanding of colposcopy was limited. Health literacy skills was the lone characteristic to significantly predict overall understanding of the Pap smear and colposcopy (unstandardized beta coefficient [SE] = 0.68 [0.02], p < .05). CONCLUSIONS: These findings demonstrate that Pap smear and colposcopy knowledge is associated with health literacy skills. Health care providers should be aware that many women lack sufficient knowledge of the Pap smear and colposcopy and tailor counseling during the clinical encounter accordingly.

Objective: The authors investigated tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis (Tdap) and influenza vaccination during pregnancy following Advisory Committee on Immunization Practices' (ACIP's) recommendation for antenatal pertussis vaccination., Methods: A retrospective chart review was performed in 2019 of women receiving prenatal care at our institution between January 1, 2014 and December 31, 2018. Receipt of ACIP-recommended vaccines were examined using Current Procedural Terminology codes to identify initiation of prenatal care, then administration of Tdap and influenza vaccines. Data were examined by individual practice (university faculty, community physicians, obstetrics and gynecology (OBGYN) residents, and family medicine residents, practice staff composition, vaccination protocol use, and insurance status. Statistical analyses were performed using χ 2 testing and χ 2 testing of linear trend., Results: Within our cohort (n = 17 973), highest vaccination uptake occurred in the university-based OBGYN faculty practice (Tdap = 58.2%, influenza = 56.5%) with lowest uptake in the OBGYN resident practice (Tdap = 28.6%, influenza = 18.5%). Higher uptake occurred in practices with standing orders, more advanced practice providers, lower provider to nursing ratios, and lower rates of Medicaid insurance., Conclusion: These data demonstrated higher vaccination uptake with standing orders, more advanced practice providers, and lower provider to nurse ratios. Future work optimizing practice staff composition and vaccination protocols may increase vaccine uptake., (© 2023 International Federation of Gynecology and Obstetrics.)

The development of vaccines is considered one of the greatest breakthroughs of modern medicine, saving millions of lives around the world each year. Despite vaccines' proven success, vaccine hesitancy remains a major issue affecting vaccine uptake. Common themes exist in patients' apprehension to receive vaccines. Women's health providers possess an important role in addressing these concerns and dispelling common misconceptions that may increase vaccine hesitancy thereby reduce vaccine uptake. This review aims to explore many of these topics as they are related to women's health and provide strategies for providers to implement which may reduce vaccine hesitancy among our patients., (Copyright © 2023 Elsevier Inc.

Background: Preterm prelabor rupture of membranes is a leading cause of preterm birth and is responsible for 18% to 20% of perinatal deaths in the United States. An initial course of antenatal corticosteroids has been shown to reduce morbidity and mortality in patients with preterm prelabor rupture of membranes. For patients who remain undelivered for 7 days or more after the initial course of antenatal corticosteroids, it is uncertain whether a booster course of antenatal corticosteroids reduces neonatal morbidity or increases the infection risk. The American College of Obstetricians and Gynecologists has concluded that the current evidence is insufficient to make a recommendation., Objective: This study aimed to evaluate if a single booster course of antenatal corticosteroids improves neonatal outcomes after preterm prelabor rupture of membranes., Study Design: We conducted a multicenter, placebo-controlled randomized clinical trial. The inclusion criteria were preterm prelabor rupture of membranes, gestational age of 24.0 to 32.9 weeks, singleton, initial antenatal corticosteroid course administered at least 7 days before randomization, and planned expectant management. Consenting patients were randomized in gestational age blocks to either receive booster antenatal corticosteroids (12 mg betamethasone every 24 hours for 2 days) or a saline placebo. The primary outcome was composite neonatal morbidity or death. A sample size of 194 patients was calculated to yield 80% power at P<.05 to detect a reduction in primary outcome from 60% in placebo group to 40% in antenatal corticosteroids group., Results: From April 2016 through August 2022, 194 patients consented and were randomized (47% of 411 eligible patients). Intent-to-treat analysis was performed on 192 patients (2 placebo patients left hospital, outcomes unknown). The groups had similar baseline characteristics. The primary outcome occurred in 64% of patients who received booster antenatal corticosteroids vs in 66% of patients who received the placebo (odds ratio, 0.82; 95% confidence interval, 0.43-1.57; gestational age-stratified Cochran-Mantel-Haenszel test). Individual components of the primary outcome and secondary neonatal and maternal outcomes were not significantly different between the antenatal corticosteroids and placebo groups. Specifically, chorioamnionitis (22% vs 20%), postpartum endometritis (1% vs 2%), wound infections (2% vs 0%), and proven neonatal sepsis (5% vs 3%) were not different between the groups., Conclusion: A booster course of antenatal corticosteroids at least 7 days after the first antenatal corticosteroids course in patients with preterm prelabor rupture of membranes did not improve neonatal morbidity or any other outcome in this adequately-powered, double-blind randomized clinical trial. Booster antenatal corticosteroids did not increase maternal or neonatal infection., (Copyright © 2023 Elsevier Inc. All rights reserved.)

Exercise guidance for women with pregnancies complicated by fetal growth restriction (FGR) is vague, despite the fact that physical activity during pregnancy improves placental development, placental blood flow, and encourages healthy fetal growth. The goal of this study is to test the hypothesis that women with pregnancies complicated by FGR are fearful of physical activity and are being given unclear or limited advice from healthcare providers. Participants (N = 78) (women who delivered an infant diagnosed with FGR within the past 5 years) took an electronic survey including demographic information, pregnancy information, provider advice recall, and other health-related information relevant to growth-restricted pregnancies. Quantitative and qualitative (post-positivism paradigm) methods were employed to analyze the data. When asked specifically about how the FGR diagnosis impacted their activity levels, nearly 50% of participants said the diagnosis led them to decrease their activity levels. Participants reported that healthcare providers who do discuss activity with pregnant patients with FGR suggest low-intensity activities or ceasing activity, although the majority of providers did not discuss activity at all. More fears surrounding physical activity were reported post-FGR diagnosis, including worrying about fetal growth and development and causing fetal harm when engaging in physical activity.

Background: Activity monitoring devices may be used to facilitate goal-setting, self-monitoring, and feedback towards a step-based physical activity (PA) goal. This study examined the performance of the wrist-worn Fitbit Charge 3™ (FC3) and sought opinions on walking and stepping-in-place from women with gestational diabetes (GDM)., Methods: Participants completed six 2-min metronome-assisted over ground bouts that varied by cadence (67, 84, or 100 steps per minute) and mode (walking or stepping-in-place; N = 15), with the sequence randomized. Steps were estimated by FC3 and measured, in duplicate, by direct observation (hand-tally device, criterion). Equivalence testing by the two one-sided tests (TOST) method assessed agreement within ± 15%. Mean absolute percent error (MAPE) of steps were compared to 10%, the accuracy standard of the Consumer Technology Association (CTA)™. A subset (n = 10) completed a timed, 200-m self-paced walk to assess natural walking pace and cadence. All participants completed semi-structured interviews, which were transcribed and analyzed using descriptive and interpretive coding., Results: Mean age was 27.0 years (SD 4.2), prepregnancy BMI 29.4 kg/m 2 (8.3), and gestational age 32.8 weeks (SD 2.6). The FC3 was equivalent to hand-tally for bouts of metronome-assisted walking and stepping-in-place at 84 and 100 steps per minute (i.e., P < .05), although walking at 100 steps per minute (P = .01) was no longer equivalent upon adjustment for multiple comparisons (i.e., at P < .007). The FC3 was equivalent to hand-tally during the 200-m walk (i.e., P < .001), in which mean pace was 68.2 m per minute (SD 10.7), or 2.5 miles per hour, and mean cadence 108.5 steps per minute (SD 6.5). For walking at 84 and 100 steps per minute, stepping-in-place at 100 steps per minute, and the 200-m walk, MAPE was within 10%, the accuracy standard of the CTA™. Interviews revealed motivation for PA, that stepping-in-place was an acceptable alternative to walking, and competing responsibilities made it difficult to find time for PA., Conclusions: The FC3 appears to be a valid step counter during the third trimester, particularly when walking or stepping-in-place at or close to women's preferred cadence.

Gestational Diabetes Mellitus (GDM) is associated with adverse health outcomes during pregnancy and beyond. Previous randomized controlled trials of exercise interventions have demonstrated that exercise, conducted primarily during supervised sessions, improves maternal glycemic control in women with GDM. However, additional research is needed to develop physical activity interventions that are easily implemented in healthcare settings (e.g., recommendations and strategies to increase non-supervised physical activity). This narrative review presents: current physical activity recommendations for pregnancy and women with GDM; the scientific literature to date on physical activity, particularly walking, and blood glucose control in GDM; rationale for physical activity interventions targeting women with GDM that are appropriate for translation to the clinical setting (e.g., lifestyle interventions that include behavioral counseling with a health coach); and the strategies employed by previous, successful lifestyle interventions for pregnant and postpartum women that were based in clinical settings.Most previous exercise interventions for blood glucose control in women with GDM have included supervised exercise sessions, and will thus be difficult to translate to the health care system. However, lifestyle interventions for weight maintenance (i.e., healthy diet and physical activity) set in the health care system and delivered by health coaches have been successfully implemented in pregnant and postpartum populations. Therefore, we suggest that future trials examine lifestyle interventions that promote unsupervised walking with evidence-based behavioral strategies (e.g., goal setting, monitoring, and feedback) and consider incorporating the use of physical activity tracking devices to support these strategies.

The purposes of this pilot study were to describe changes in breastmilk lipid content in response to an acute bout of moderate intensity exercise and to explore maternal metabolic health factors, including metabolic flexibility, which may impact this change. A cross-sectional, observational, pilot study design was performed in 14 women between 4 and 6 months postpartum. Whole body fasting lipid oxidation was assessed, a standardized high-fat breakfast was consumed, and lipid oxidation was again measured 120-minutes post-meal. Metabolic flexibility was determined by comparing the change in lipid oxidation before and after the meal. Women completed 30-minutes of moderate intensity treadmill walking 150-minutes post-meal. Breastmilk was expressed and analyzed for lipid content before and after exercise. Overall, there was no significant difference between pre- and post-exercise breastmilk lipid content (pre-exercise 59.4±36.1 g/L vs. post-exercise 52.5±20.7 g/L, p=0.26). However, five (36%) women had an increase in breastmilk lipid content in response to the exercise bout, compared to nine (64%) that had a decrease in breastmilk lipid content suggesting inter-individual variability. The change in breastmilk lipid content from pre- to post-exercise was positively correlated to metabolic flexibility (r=0.595, p=0.03). Additionally, post-exercise lipid content was positively correlated with body mass index (BMI), body composition, and postpartum weight retention. Preliminary findings from this pilot study suggest that metabolic flexibility and maternal weight status may help explain the inter-individual changes in breastmilk lipid content in response to an acute bout of moderate intensity exercise.

The American College of Obstetricians and Gynecologists recommends medication-assisted treatment (MAT) for pregnant women who misuse opioids rather than detoxification because of possible relapse and dropout from treatment (ACOG, 2017). In a prospective study, fifty-five pregnant women with an opioid use disorder were offered a choice of MAT or detoxification. Ethical concerns precluded random assignment. We assessed dropout, treatment outcome, relapse, other illicit drug use, infant neonatal opioid withdrawal syndrome (NOWS), and childhood sexual abuse. Of 55 women, 13 initially chose MAT and 42 women chose detoxification. All women received behavioral support. No one dropped out of treatment prior to delivery. All women who chose MAT initially remained on MAT. Of women who chose detoxification, 23% switched to MAT, 30% tapered below initial MAT doses, and 45% fully detoxified by delivery. There was a significant difference in opioid relapse between women on MAT (26%) and those who detoxified (0%), but no differences for other illicit drug use. Infants of women on MAT were more likely to have neonatal NOWS (91%) than infants of women who tapered below initial MAT doses but did not fully detoxify (62%). Infants of mothers who tapered (62%) were more likely to have NOWS than infants of women who fully detoxified (0%). Women on MAT reported significantly lower sexual abuse severity than did women who tapered or detoxified. It is critical to replicate the current findings and to follow up with mothers and their infants postpartum to ascertain the long-term impact of tapering or detoxification during pregnancy., Competing Interests: The authors declared that there is no conflict of interest., (© 2020 The Authors.)

This study examined the relationship between borderline personality disorder assessed as self-reported borderline features (Morey, 1991), opioid use, and Hepatitis C virus (HCV) in pregnant women. There were 55 women in the opioid use group and 38 in the comparison group who were at high risk due to medical issues that did not include drug use. Women were in their 2nd or 3rd trimester. All women received Medicaid and were racially representative of the geographic area (84% White). We assessed opioid use severity from medical records based on urine assays and prescriptions for opioids. The results revealed that women who scored in the clinical range of total borderline features, which is associated with a diagnosis of borderline personality disorder (Trull, 1995), had 2.83 greater odds of being opioid users (prescribed and nonprescribed) than had individuals below the cutoff. The borderline features of affective instability, identity disturbance, negative relationships, and self-harm/impulsivity were significantly correlated with opioid use severity. Negative relationships and self-harm/impulsivity contributed significant variance in opioid use severity over and above affective instability and identity disturbance. Women in the clinical range of borderline features were more likely to have HCV than were women below the cutoff, and the borderline feature of negative relationships specifically was associated with HCV. We discuss implications for interventions to address negative relationships and self-harm/impulsivity and interventions to help prevent opioid misuse in women before they become pregnant.

There is an association between the experience of childhood maltreatment and opioid misuse in adults, especially for women. However, we know little about this association in pregnancy, and less about processes that could be the target of interventions to help women better parent their infants. We examined reflective functioning as a putative process. Reflective functioning is the ability to interpret one's own and others' behavior in terms of underlying mental states, e.g., emotions, motivations, and beliefs. We sampled 55 pregnant women who misused opioids and 38 women at high risk due to medical factors, e.g., heart disease. We assessed maltreatment with the Maltreatment and Abuse Chronology of Exposure (MACE; Teicher & Parigger, 2015), and reflective functioning with the Reflective Functioning Questionnaire (RFQ; Fonagy et al., 2016). Maltreatment variables included the sum of severity across all subtypes, number of subtypes experienced, and severity of sexual, physical, and emotional abuse, and of neglect. We created a categorical opioid user group variable: women who used opioids in pregnancy vs. high-risk medical comparisons. We found that women who used opioids in pregnancy had poorer reflective functioning than did high-risk medical comparisons. We also created an opioid use severity scale (ranging from 0 to 3) from urine assays and history of prescribed opioids from medical records. Using Hayes (2012)'s bootstrapping PROCESS macro, we found that reflective functioning mediated the association between all maltreatment variables and opioid use severity. We discuss the results in terms of how best to intervene to improve women's reflective functioning, which may help their ability to parent., (Copyright © 2019 Elsevier Ltd. All rights reserved.)

Objective: The primary current recommendation for infant follow-up postdelivery from a hepatitis C virus (HCV) viral load positive mother is to evaluate for the presence of antibody at or after 18 months of age. Our study objective was to analyze compliance with this recommendation for postdelivery infant HCV screening at our institution among a cohort of infants delivered from HCV viral load positive mothers. Methods: Starting 1 January, 2015, a prospective database was developed for all pregnancies that involved mothers with a positive HCV viral load during pregnancy. This short report describes the infant follow-up for deliveries through 30 June, 2016. At hospital discharge, all neonates were given follow-up pediatric appointments and mothers were supplied the date and time of the appointment along with the pediatric group name, office directions, and phone number. Statistics involved simple percentages with Poisson binomial 95% confidence intervals. Results: A total of 127 newborns were delivered of HCV viral load positive mothers during the study period and 55 (43%, 95% CI 35-52%) attended their pediatric appointments and were still in follow-up. Regarding the 72 cases (57%, 95% CI 48-65%) not in follow-up, 24 (19%, 95% CI 13-27%) never presented to care and 48 (38%, 95% CI 29-47%) came to one or two visits shortly after delivery but were absent for further follow-up. Conclusions: These data demonstrate that follow-up at 18 months postdelivery from an HCV viral load positive mother occurs in less than half of the cases and alternative screening strategies should be evaluated.

Objective  To evaluate fetomaternal bleeding following routine cesarean delivery compared with cesarean delivery involving transplacental transection. Study Design  A prospective cohort study evaluating cesarean delivery in which the placenta was transected (cases) versus controls (placenta not transected) from January 2016 to April 2018. A maternal Kleihauer-Betke's (KB) test and newborn hematocrit were performed shortly after delivery. Results  The rate of a positive KB test was not significantly different between cases ( n  = 31) and controls ( n  = 61) (19 vs. 14%; odds ratio [OR]: 1.44; 95% confidence interval [CI]: 0.46-4.49; p  = 0.74). Median neonatal hematocrits were not different. However, the rate of newborn hematocrits <40% at delivery was higher in cases compared with controls (23 vs. 3%; OR: 8.90; 95% CI: 1.72-45.90; p  = 0.005). Conclusion  A cesarean requiring transplacental transection to accomplish delivery does not significantly increase the rate of fetomaternal bleeding but is associated with a higher likelihood of newborn hematocrit <40% at delivery.

Background: Little is known of the burden of Group B Streptococcus (GBS) colonization among pregnant women in Jordan. We conducted a pilot study to determine the prevalence of GBS among pregnant women in Amman, Jordan, where GBS testing is not routine. We also explored GBS serotypes and the performance of a rapid GBS antigen diagnostic test., Methods: We collected vaginal-rectal swabs from women who presented for labor and delivery at Al-Bashir Hospital. Three methods were used to identify GBS: Strep B Rapid Test (Creative Diagnostics), blood agar media (Remel) with confirmed with BBL Streptocard acid latex test (Becton Dickinson), and CHROMagar StrepB (Remel). Results were read by a senior microbiologist. We defined our gold standard for GBS-positive as a positive blood agar culture confirmed by latex agglutination and positive CHROMagar. PCR testing determined serotype information. Demographic and clinical data were also collected., Results: In April and May 2015, 200 women were enrolled with a median age of 27 years (IQR: 23-32); 89.0% were Jordanian nationals and 71.9% completed secondary school. Median gestational age was 38 weeks (IQR: 37-40); most women reported prenatal care (median 9 visits; IQR: 8-12). Median parity was 2 births (IQR: 1-3). Pre-pregnancy median BMI was 24.1 (IQR: 21.5-28.0) and 14.5% reported an underlying medical condition. Obstetric complications included gestational hypertension (9.5%), gestational diabetes (6.0%), and UTI (53.5%), of which 84.5% reported treatment. Overall, 39 (19.5%) of women were GBS-positive on blood agar media and CHROMagar, while 67 (33.5%) were positive by rapid test (36% sensitivity, 67% specificity). Serotype information was available for 25 (64%) isolates: III (48%), Ia (24%), II (20%), and V (8%). No demographic or clinical differences were noted between GBS+ and GBS-negative women., Conclusions: Nearly one in five women presenting for labor in Jordan was colonized with GBS, with serotype group III as the most common. The rapid GBS antigen diagnostic had low sensitivity and specificity. These results support expanded research in the region, including defining GBS resistance patterns, serotyping information, and risk factors. It also emphasizes the need for routine GBS testing and improved rapid GBS diagnostics for developing world settings.

Objectives: To compare head circumference (HC) in neonates treated for neonatal abstinence syndrome (NAS) with control neonates without antenatal opioid exposure., Methods: Our prospective cohort study ran from April 1, 2014, through December 31, 2016. Newborns treated for NAS delivered from well-dated pregnancies ≥34 weeks' gestation were compared with newborns who were nonopioid exposed and matched for race, parity, mode of delivery, and gestational age. All mothers underwent serial antenatal urine drug testing. A minimum of 754 study participants were needed (377 in each group) to demonstrate an increase in the proportion of newborns with HCs less than or equal to the 10th percentile from 10% in controls to a minimum of 20% in NAS newborns with 90% power., Results: A total of 858 neonates were enrolled (429 NAS cases and 429 controls). Mean HC for cases was 33.04 cm (±1.9 cm) compared with 33.99 cm (±2.0 cm) for controls ( P < .0001). Among the 429 NAS cases, the mothers of 372 (87%) were on opioid medication-assisted treatment. For NAS cases, 30.1% (95% confidence interval: 25.8%-34.7%) had an HC less than or equal to the 10th percentile (129 of 429 neonates), and 8.2% (95% confidence interval: 5.8%-11.2%) had an HC less than or equal to the third percentile (35 of 429 neonates). Multivariate analysis was used and determined that only chronic opioid use during gestation resulting in a neonate who was NAS treated was a significant risk factor for the observed smaller HC., Conclusions: Chronic opioid use during pregnancy sufficient to cause NAS was associated with smaller HCs at birth. Most mothers were on opioid agonist medication-assisted treatment, which is currently the recommended treatment option during pregnancy., Competing Interests: POTENTIAL CONFLICT OF INTEREST: The authors have indicated they have no potential conflicts of interest to disclose., (Copyright © 2019 by the American Academy of Pediatrics.)

BACKGROUND Dyspnea in pregnancy is common and attributable to a variety of etiologies including normal physiology. The obstetric provider is challenged with distinguishing between physiologic versus pathologic dyspnea. CASE REPORT A 31-year-old G2 P1001 female at 34 weeks gestation presented with dyspnea, tachycardia, and inability to lie supine. Imaging revealed a large heterogeneous anterior mediastinal mass (14.8×11.5 cm). Multidisciplinary coordinated care led to diagnosis of B cell lymphoma, delivery via cesarean section under regional anesthesia in steep Trendelenberg position, followed by chemotherapy postpartum. CONCLUSIONS Dyspnea in pregnancy is common but might represent underlying pathology. While an obstetrician is knowledgeable of physiologic pregnancy changes, he or she should remain vigilant for underlying pathologic causes of dyspnea, including malignancy. Anterior mediastinal masses propose unique anesthetic challenges including respiratory impairment and cardiopulmonary collapse requiring collaborative care and planning.

Objective: Tetanus toxoid, reduced diphtheria toxoid, and acellular pertusiss (Tdap) vaccine is recommended during each pregnancy, regardless of prior receipt. Data on reactogenicity and immunogenicity, particularly after repeated Tdap, are limited. We compared local injection-site and systemic reactions and serologic response following Tdap in (1) pregnant and nonpregnant women and (2) pregnant women by self-reported prior Tdap receipt., Study Design: Pregnant women (gestational age 20-34 weeks) and nonpregnant women receiving Tdap were enrolled in this observational study. Injection-site and systemic reactions were assessed for one week post-vaccination. Pertussis toxin, filamentous hemagglutinin, pertactin, fimbriae, tetanus and diphtheria specific IgG antibody titers were determined by standardized enzyme-linked immunosorbent assay at baseline and 28 days post-vaccination. Reactogenicity and serologic responses were compared by pregnancy status, and within pregnant women by self-reported prior Tdap receipt., Results: 374 pregnant and 225 nonpregnant women were vaccinated. Severe local or systemic reactions or "any" fever were uncommon (≤3% for both groups). Moderate/severe injection-site pain was significantly higher in pregnant (17.9%) versus nonpregnant (11.1%) women, but did not prompt a healthcare visit. Proportions of other moderate/severe or any severe reactions were not significantly higher in pregnant compared to nonpregnant women. Moderate/severe (including pain) and severe reactions were not significantly higher in pregnant women receiving repeat versus first-time Tdap. Antibody titers increased from baseline to post-vaccination for all vaccine antigens in pregnant and nonpregnant women; post-vaccination titers against pertussis toxin and filamentous hemagglutinin were significantly higher in nonpregnant versus pregnant women (p < 0.01)., Conclusion: Tdap was well-tolerated in pregnant and nonpregnant women. Pregnant women were more likely to report moderate/severe pain at the Tdap injection-site compared with nonpregnant women, but did not necessitate medical visits. Prior Tdap receipt did not increase occurrence of moderate/severe local or systemic reactions in pregnant women. Serologic responses to all vaccine antigens were robust.

Opioid misuse has become one of the most pressing public health problems facing the country. In this article, we briefly review literature regarding the opioid epidemic in the United States and the negative consequences of opioid use disorder. We provide information regarding treatment and relapse using a variety of intervention approaches. We call for research on people with opioid use disorder that can contribute to a variety of areas: improving medication-assisted treatment, addressing chronic pain, examination of adjunctive behavioral interventions, overdose, high risk behaviors and infections, pregnancy, diverse populations, and other psychological factors. Collectively addressing these crucial areas of research will advance the field and help alleviate suffering and prevent death from opioid use disorder., Competing Interests: Declaration of conflicting interests:The author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Pregnant women are at risk for infection and may have significant morbidity or mortality. Influenza, pertussis, zika, and cytomegalovirus produce mild or asymptomatic illness in the mother, but have profound implications for her fetus. Maternal immunization can prevent or mitigate infections in pregnant women and their infants. The Advisory Committee of Immunization Practices recommends 2 vaccines during pregnancy: inactivated influenza, and tetanus toxoid, reduced diphtheria toxoid, and acellular pertussis during pregnancy. The benefits of MMR, varicella, and other vaccines are reviewed. Novel vaccine studies for use during pregnancy for prevention of illness are explored., (Copyright © 2018 Elsevier Inc.

Background: The United States currently has an opioid use disorder epidemic and research evaluating ways to minimize the use of opioids postsurgery are needed. One of these options is intravenous acetaminophen. If the use of preoperative intravenous acetaminophen was found to be effective for cesarean delivery, this would be beneficial for both the mother and breast-feeding neonate., Objective: The primary study objective was to see if maternal opioid use was significantly less in the postoperative period for the study group that received 1 g of intravenous acetaminophen preoperatively compared with a control group that received placebo. The secondary objectives were to evaluate maternal length of stay and pain scores postoperatively, and assess the acetaminophen level in cord blood at delivery., Study Design: This study was a prospective double-blinded randomized placebo-controlled trial. All pregnant patients who entered labor and delivery for a scheduled cesarean from November 2015 through April 2017 were eligible. Once consented, the medication was supplied by the pharmacy department, which performed the blinded randomization. Both the study drug of 1000 mg (1 g) of acetaminophen and placebo of normal saline were distributed as unmarked 100-mL bags administered over 15 minutes just prior to incision. No study personnel from the obstetric or anesthesia departments had any access to the randomization. Based on a power analysis using the published surgical data results, the goal was to obtain a minimum of 100 patients (50 patients in each arm). Primary data collection included demographics, number of opioid doses and morphine milligram equivalents administered to the patient postoperatively, length of stay postdelivery, pain scores, and newborn cord blood acetaminophen levels. Exclusions were maternal acetaminophen allergy, receipt of acetaminophen in the prior 24 hours, opioid use disorder, and hepatitis/liver impairment. Statistics involved χ 2 , Fisher exact, and the Student t test where appropriate and a P value <.05 was considered significant with all tests considered against a 2-sided alternative hypothesis., Results: A total of 105 patients were evaluated with 51 who received intravenous acetaminophen and 54 who received placebo. The number of postoperative opioid medication doses administered to the study group was 11.1 (±8.9) compared with the number received by the control group of 10.5 (±8.5), P = .72. The morphine milligram equivalents in the study group was 94.2 (±40.4) compared with the control group of 90.7 (±42.1), P = .67. The length of stay and pain scores were not different between the groups. All of the umbilical cord blood values for acetaminophen were subtherapeutic., Conclusion: These data demonstrate that for cesarean delivery, the use of a preoperative 1-g intravenous dose of acetaminophen does not decrease the number of opioid medication doses or the morphine milligram equivalents administered postoperatively, nor does it decrease length of stay postcesarean. The administration of 1-g intravenous acetaminophen preoperatively does not result in elevated newborn cord blood levels (ClinicalTrials.govNCT02694653)., (Copyright © 2017 Elsevier Inc.

Maternal immunization is an effective strategy to prevent and/or minimize the severity of infectious diseases in pregnant women and their infants. Based on the success of vaccination programs to prevent maternal and neonatal tetanus, maternal immunization has been well received in the United States and globally as a promising strategy for the prevention of other vaccine-preventable diseases that threaten pregnant women and infants, such as influenza and pertussis. Given the promise for reducing the burden of infectious conditions of perinatal significance through the development of vaccines against relevant pathogens, the Division of Microbiology and Infectious Diseases, National Institute of Allergy and Infectious Diseases, National Institutes of Health (NIH) sponsored a series of meetings to foster progress toward clinical development of vaccines for use in pregnancy. A multidisciplinary group of stakeholders convened at the NIH in December 2013 to identify potential barriers and opportunities for scientific advancement in maternal immunization., (© The Author 2014.

Objective: Bacterial colonization of the fetal membranes and its role in pathogenesis of membrane rupture is poorly understood. Prior retrospective work revealed chorion layer thinning in preterm premature rupture of membranes (PPROM) subjects. Our objective was to prospectively examine fetal membrane chorion thinning and to correlate to bacterial presence in PPROM, preterm, and term subjects., Study Design: Paired membrane samples (membrane rupture and membrane distant) were prospectively collected from: PPROM = 14, preterm labor (PTL = 8), preterm no labor (PTNL = 8), term labor (TL = 10), and term no labor (TNL = 8), subjects. Sections were probed with cytokeratin to identify fetal trophoblast layer of the chorion using immunohistochemistry. Fluorescence in situ hybridization was performed using broad range 16 s ribosomal RNA probe. Images were evaluated, chorion and choriodecidua were measured, and bacterial fluorescence scored. Chorion thinning and bacterial presence were compared among and between groups using Student's t-test, linear mixed effect model, and Poisson regression model (SAS Cary, NC)., Results: In all groups, the fetal chorion cellular layer was thinner at rupture compared to distant site (147.2 vs. 253.7 µm, p<0.0001). Further, chorion thinning was greatest among PPROM subjects compared to all other groups combined, regardless of site sampled [PPROM(114.9) vs. PTL(246.0) vs. PTNL(200.8) vs. TL(217.9) vs. TNL(246.5)]. Bacteria counts were highest among PPROM subjects compared to all other groups regardless of site sampled or histologic infection [PPROM(31) vs. PTL(9) vs. PTNL(7) vs. TL(7) vs. TNL(6)]. Among all subjects at both sites, bacterial counts were inversely correlated with chorion thinning, even excluding histologic chorioamnionitis (p<0.0001 and p = 0.05)., Conclusions: Fetal chorion was uniformly thinner at rupture site compared to distant sites. In PPROM fetal chorion, we demonstrated pronounced global thinning. Although cause or consequence is uncertain, bacterial presence is greatest and inversely correlated with chorion thinning among PPROM subjects.

The Division of Microbiology and Infectious Diseases at the National Institute of Allergy and Infectious Diseases, National Institutes of Health organized a series of conferences, entitled "Enrolling Pregnant Women in Clinical Trials of Vaccines and Therapeutics", to discuss study design and the assessment of safety in clinical trials conducted in pregnant women. A panel of experts was charged with developing guiding principles for the design of clinical trials and the assessment of safety of vaccines during pregnancy. Definitions and a grading system to evaluate local and systemic reactogenicity, adverse events, and other events associated with pregnancy and delivery were developed. The purpose of this report is to provide investigators interested in vaccine research in pregnancy with a basic set of tools to design and implement maternal immunization studies which may be conducted more efficiently using consistent definitions and grading of adverse events to allow the comparison of safety reports from different trials. These guidelines and safety assessment tools may be modified to meet the needs of each particular protocol based on evidence collected as investigators use them in clinical trials in different settings and share their findings and expertise., (Copyright © 2013 Elsevier Ltd.

Experts in obstetrics, maternal-fetal medicine, infectious diseases, pediatrics, neonatology, genetics, vaccinology and clinical trial design were charged with identifying normal ranges for vital signs and laboratory assessments in pregnancy. A grading system for adverse events was then developed., (Copyright © 2013 Elsevier Ltd. All rights reserved.)

Objective: To determine whether cervical dilation at the time of physical examination indicated cerclage placement can predicts latency and gestational age at delivery., Methods: A retrospective cohort study of all women who underwent physical examination indicated cerclage placement from 1996 to 2011 at Duke University Hospital (DUH) was performed. Physical examination indicated cerclage was defined as cerclage placement after 16 weeks in women with a cervical length of less than 2.5 cm and/or cervical dilation greater than or equal to 1 cm at time of procedure. Subjects were divided into two groups depending on cervical dilation at time of procedure (2 cm, <2 cm) for comparison. A multivariate linear regression model for the outcome gestational age of delivery was constructed, controlling for confounding variables., Results: A total of 110 women with complete data were available for analysis. Median gestational age at cerclage placement was similar between the two groups (20.3 vs. 20.3 weeks, p = 0.8). Women with cervical dilatation ≥ 2 cm dilation delivered at an earlier median gestational age than women with cervical dilation <2 cm (27.0 vs. 35.6 weeks, p < 0.001). Cervical dilation at the time of cerclage placement independently predicted gestational age at delivery while controlling for use of intracervical Foley balloon catheter for membrane reduction, cerclage suture type, history of prior preterm birth, race, insurance status, and tobacco use., Conclusions: Women who receive a rescue cerclage are more likely to deliver at an earlier gestational age when cervical dilation is ≥ 2 cm at the time of procedure.

Unlabelled: Vaccinations in pregnancy are an important aspect of prenatal care and of improving not only maternal health but also neonatal outcomes. Only 2 vaccines are specifically recommended during pregnancy: influenza and tetanus, diphtheria, and acellular pertussis (Tdap). Because influenza illness disproportionately affects pregnant women compared with other populations, annual prevention of influenza illness is recommended for all women who will be pregnant during influenza season (October to May). Influenza vaccination has been recently reported to also result in decreased febrile respiratory illnesses in the newborn, likely through passive antibody transfer. Pertussis infection rates are rising in the United States as vaccine-induced immunity wanes, with the mortality burden primarily seen in infants aged <6 months. Pertussis immunization with Tdap is now recommended for all pregnant women during the late second (>20 weeks) or third trimester with the intent to both protect the pregnant woman and provide passive antibody to the infant before vaccination at 2 months of age. Provider support for these recommendations regarding both annual influenza vaccination and postpartum Tdap vaccination during pregnancy is critical to ensuring vaccine delivery and improving both maternal and fetal health. The article reviews the epidemiology and clinical aspects of influenza and pertussis infection with particular attention to pregnancy and recommendations for vaccination in these women., Target Audience: Obstetricians and gynecologists, ophthalmologists, neurologists, family physicians, emergency room physicians, Learning Objectives: After completing this CME activity, obstetricians and gynecologists should be better able to analyze how influenza infection disproportionally affects pregnant women. Assess how influenza vaccination improves maternal and likely neonatal outcomes. Evaluate pertussis infection and immunity in adults, and counsel pregnant women as to the benefits of Tdap vaccination, particularly for the infant.
