RESUMEN

OBJECTIVE: This study was aimed to investigate delivery management of patients with antepartum stillbirth. STUDY DESIGN: Using data from fetal death certificates and linked maternal hospital discharge records, we identified a population-based sample of patients with singleton antepartum stillbirth at 20 to 42 weeks of gestation in California in 2007 to 2011. Primary outcomes were intended mode of delivery and actual mode of delivery. We used multivariable regressions to examine the association between patient demographic, clinical, and hospital characteristics and their mode of delivery. Separate analysis was performed for patients who had prior cesarean delivery versus those who did not. RESULTS: Of 7,813 patients with singleton antepartum stillbirth, 1,356 had prior cesarean, while 6,457 had no prior cesarean. Labor was attempted in 51.8% of patients with prior cesarean and 93.7% of patients without prior cesarean, with 76.2 and 95.8% of these patients, respectively, delivered vaginally. Overall, 18.9% of patients underwent a cesarean delivery (60.5% among those with prior cesarean and 10.2% among those without prior cesarean). Multivariable regression analysis identified several factors associated with the risk of cesarean delivery that were not medically indicated. For instance, among patients without prior cesarean, malpresentation (of which the vast majority was breech presentation) was associated with an increased likelihood of planned cesarean (adjusted odds ratio [OR] = 3.26, 95% confidence interval [CI]: 2.53-4.22) and cesarean delivery after attempting labor (adjusted OR = 3.09, 95% CI: 2.25-4.25). For both patients with and without prior cesarean, delivery at an urban teaching hospital was associated with a lower likelihood of planned cesarean and a lower likelihood of cesarean delivery after attempting labor (adjusted ORs ranged from 0.28 to 0.56, p < 0.001 for all). CONCLUSION: Over one in six patients with antepartum stillbirth underwent cesarean delivery. Among patients who attempted labor, rate of vaginal delivery was generally high, suggesting a potential opportunity to increase vaginal delivery in this population. KEY POINTS: · In singleton antepartum stillbirths, 18.9% underwent cesarean delivery.. · Rate of vaginal delivery was high when labor was attempted.. · Both clinical and non-clinical factors were associated with risk of cesarean delivery..

RESUMEN

BACKGROUND: Current consensus recommendations are to not initiate cervical cancer screening for immunocompetent adolescent females before 21 years of age. This is in part because of the very low rate of 0.8 per 100,000 new cervical cancer cases diagnosed among women aged between 20 to 24 years. Timely human papillomavirus vaccination further decreases the incidence of cervical cancer to 4 cases per 100,000 persons by the age of 28 years. Screening before 21 years of age has demonstrated no clear benefit in cancer risk reduction or outcomes. In addition, unindicated screening among adolescents can lead to patient harm and increasing costs to the healthcare system. OBJECTIVE: It is important to assess the rates of overutilization of cervical cancer screening and to identify areas where improvements have occurred and where further opportunities exist. This study aimed to assess the trends over time and the practice and provider factors associated with unindicated cervical cancer screening tests in adolescent females within the largest healthcare system in the state. STUDY DESIGN: Cross-sectional data from patients aged 13 to 20 years who underwent cervical cancer screening between January 1, 2012, and December 31, 2018, across a large multihospital health system were reviewed. All cervical cancer screening results were included. The incidence rate of unindicated screening was analyzed over 6-month intervals using the Poisson regression analysis. RESULTS: The study included data from 118 providers and 794 women. Among the 900 screening results, most (90%) were unindicated: 87% with unindicated cytology testing alone and 14% with unindicated human papillomavirus testing. Screening tests were collected from patients aged 13 to 20 years, many of whom had multiple unindicated cytology tests, with 25 patients having ≥3 tests before the age of 21 years. Most results of cytology testing were negative for intraepithelial lesion or malignancy (77%). Moreover, 52 invasive diagnostic or therapeutic procedures (49 colposcopies and 3 conizations) were performed, of which 45 (87%) followed an unindicated screening test. Between 2012 and 2018, the incidence rate of unindicated cytology decreased by 33% (12.6 to 8.5 unindicated cytology per 1000 encounters). The incidence rate of unindicated screening was lower in the academic setting than in the community setting (incidence rate ratio, 0.43; P<.01). Even with decreases in the overall rates of unindicated screening throughout the study period, there were still 58 unindicated screening tests performed in the final year of this study. CONCLUSION: Despite substantial reductions in unindicated screening for women aged <21 years, there remained areas for improvement. Our data reflected practices of guideline nonadherence up to 7 years after the 2012 guideline. Now, with a new series of changes to the guidelines, which may be even more challenging for patients and providers, it is more important than ever to utilize evidence-based strategies to improve guideline dissemination and adherence.

RESUMEN

BACKGROUND AND AIM: We report a case of intravenous drug use associated tricuspid valve endocarditis in a 28-year-old pregnant female at 26-week gestation. METHODS: Patient management required a multidisciplinary collaboration between cardiac surgery, obstetrics and gynecology, and neonatal critical care. RESULTS: Despite appropriate intravenous antibiotics, the patient developed life-threatening complications and underwent planned cesarean delivery at 28 weeks 6 days gestation followed by interval tricuspid valve replacement 1 week later. CONCLUSIONS: Both the patient and her infant were successfully managed through the perioperative period.

RESUMEN

STUDY OBJECTIVE: To demonstrate a surgical video of laparoscopic management of an appendiceal mass preoperatively misdiagnosed as a pelvic mass. This study was deemed to be exempt from the Yale New Haven Hospital Institutional Review Board. DESIGN: A step-by-step explanation of the diagnosis and laparoscopic management of an appendiceal mass using an instructive video (Canadian Task Force classification III). SETTING: A teaching hospital in New Haven, Connecticut. PATIENT: A 53-year-old multiparous perimenopausal woman. INTERVENTION: Laparoscopic management of an appendiceal mass. MEASUREMENTS AND MAIN RESULTS: A 53-year-old multiparous perimenopausal patient underwent workup for pelvic pain. Pelvic imaging revealed a 72 × 35 × 28 mm cystic structure abutting the uterine fundus with thin partial septum but no mural nodules or concomitant pelvic lymphadenopathy. Exploratory laparoscopy showed unremarkable pelvic anatomy. After the entire small bowel was run, the cystic structure abutting the uterine fundus was deemed to be an appendiceal mass. The observed convergence of the 3 taeniae coli at the junction of the cecum with the cystic mass confirmed the diagnosis. For laparoscopic resection the umbilical fold port site was extended to 12 mm to introduce the Endo GIA stapler (Medtronic, Minneapolis, MN). The appendiceal mass was stabilized in view with a laparoscopic grasper, and the stapler was articulated to fit the base of the appendix without narrowing the lumen of the cecum. The specimens were removed through the umbilical port site in a laparoscopic bag without spillage. Pathology returned low-grade appendiceal mucinous neoplasm with no evidence of invasion. The patient was managed appropriately with laparoscopic appendectomy and discharged home on the day of surgery. CONCLUSION: Appendiceal masses should be considered in the differential diagnosis of a presumed pelvic mass. For low-grade appendiceal mucinous neoplasms that are diagnosed intraoperatively, laparoscopic resection without spillage or rupture is a feasible and appropriate approach for treatment [1-3].

RESUMEN

BACKGROUND: Preeclampsia is a leading cause of maternal morbidity, and dyslipidemia has been associated with preeclampsia in observational studies. We use Mendelian randomization analyses to estimate the association between lipid levels, their pharmacological targets, and the risk of preeclampsia in 4 ancestry groups. METHODS: We extracted uncorrelated (R2<0.001) single-nucleotide polymorphisms strongly associated (P<5×10-8) with LDL-C (low-density lipoprotein cholesterol), HDL-C (high-density lipoprotein cholesterol), and triglycerides from genome-wide association studies of European, admixed African, Latino, and East Asian ancestry participants. Genetic associations with risk of preeclampsia were extracted from studies of the same ancestry groups. Inverse-variance weighted analyses were performed separately for each ancestry group before they were meta-analyzed. Sensitivity analyses were conducted to evaluate bias due to genetic pleiotropy, demography, and indirect genetic effects. RESULTS: The meta-analysis across 4 ancestry groups included 1.5 million subjects with lipid measurements, 7425 subjects with preeclampsia, and 239 290 without preeclampsia. Increasing HDL-C was associated with reduced risk of preeclampsia (odds ratio, 0.84 [95% CI, 0.74-0.94]; P=0.004; per SD increase in HDL-C), which was consistent across sensitivity analyses. We also observed cholesteryl ester transfer protein inhibition-a drug target that increases HDL-C-may have a protective effect. We observed no consistent effect of LDL-C or triglycerides on the risk of preeclampsia. CONCLUSIONS: We observed a protective effect of elevated HDL-C on risk of preeclampsia. Our findings align with the lack of effect in trials of LDL-C modifying drugs but suggest that HDL-C may be a new target for screening and intervention.

RESUMEN

BACKGROUND: The vaginal birth after cesarean delivery calculator by the Maternal-Fetal Medicine Units Network was created to help providers counsel patients on predicted success of trial of labor after cesarean delivery using individualized risk assessment. The inclusion of race and ethnicity as predictors of vaginal birth after cesarean delivery in the 2007 calculator was problematic and potentially exacerbated racial disparities in obstetrics. Thus, a modified calculator without race and ethnicity was published in June 2021. OBJECTIVE: This study aimed to assess the accuracy of the 2007 and 2021 Maternal-Fetal Medicine Units vaginal birth after cesarean delivery calculators in predicting vaginal birth after cesarean delivery success among racial/ethnic minority patients receiving obstetrical care at a single urban tertiary medical center. STUDY DESIGN: All patients with 1 previous low transverse cesarean delivery who underwent a trial of labor at term with a vertex singleton gestation at an urban tertiary medical center from May 2015 to December 2018 were reviewed. Demographic and clinical data were collected retrospectively. Associations between maternal characteristics and success of vaginal birth after cesarean delivery were assessed using univariate and multivariable logistic regression. Predicted vaginal birth after cesarean delivery success rates using the Maternal-Fetal Medicine Units calculator were compared with actual outcomes (ie, successful trial of labor after cesarean delivery/vaginal birth after cesarean delivery vs repeated cesarean delivery) across each racial and ethnic group. RESULTS: A total of 910 patients met eligibility criteria and attempted trial of labor after cesarean delivery; 662 (73%) achieved vaginal birth after cesarean delivery. The rate of vaginal birth after cesarean delivery was highest among Asian women (81%) and lowest among Black women (61%). Univariate analyses demonstrated that success of vaginal birth after cesarean delivery was associated with maternal body mass index <30 kg/m2, history of vaginal delivery, and absence of indication of arrest of dilation or descent for previous cesarean delivery. Multivariate analyses evaluating predictors of vaginal birth after cesarean delivery reported in the 2021 calculator showed that maternal age, history of arrest disorder for previous cesarean delivery, and treated chronic hypertension were not significant in our patient population. Most patients who were of White, Asian, or "Other" race with a vaginal birth after cesarean delivery had a 2007 calculator-predicted probability of vaginal birth after cesarean delivery of >65%, whereas most Black and Hispanic patients with a vaginal birth after cesarean delivery were more likely to have a predicted probability of vaginal birth after cesarean delivery between 35% and 65% (P<.001). Most White, Asian, and Other-race patients with a repeated cesarean delivery had a 2007 calculator-predicted probability of vaginal birth after cesarean delivery of >65%, whereas most Black and Hispanic patients with a repeated cesarean delivery had a predicted probability of vaginal birth after cesarean delivery between 35% and 65%. Across all racial and ethnic groups, most patients with a vaginal birth after cesarean delivery had a 2021 calculator-predicted probability of vaginal birth after cesarean delivery of >65%. CONCLUSION: The inclusion of race/ethnicity in the 2007 Maternal-Fetal Medicine Units vaginal birth after cesarean delivery calculator underestimated predicted vaginal birth after cesarean delivery success rates among Black and Hispanic patients receiving obstetrical care at an urban tertiary medical center. Thus, we support the use of the 2021 vaginal birth after cesarean delivery calculator without race/ethnicity. Excluding race and ethnicity from vaginal birth after cesarean delivery counseling may be one way in which providers can ultimately contribute toward the reduction of racial and ethnic disparity in maternal morbidity in the United States. Further research is needed to understand the implications of treated chronic hypertension for the success of vaginal birth after cesarean delivery.

RESUMEN

OBJECTIVE: To compare the cardiometabolic risk (CMR) profile of premenopausal and postmenopausal women with spinal cord injury (SCI). METHOD: Post hoc analysis of a multicenter cross-sectional study assessing CMR. Seventeen women with ASIA Impairment Scale (AIS) A or B SCI between C5 and T12 were stratified into 2 groups according to menopausal status (11 premenopausal vs 6 postmenopausal women). Data collected included demographic, social, medical, menopausal, hormone use, and menstrual histories. Assessments included physical, anthropometric, and blood pressure measures; fasting serum total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), and hemoglobin A1C (Hb1Ac); calculated low-density lipoprotein (LDL-C); and an oral glucose tolerance test. RESULTS: The premenopausal group had a mean age of 32.4 years compared with 56.0 years in the postmenopausal group. Similar group findings included body mass index (BMI) (22.4 vs 22.2), HDL-C (52.5 vs 53 mg/dL), HbA1c (4.9 vs 5.1%), fasting blood glucose (FBG) (79.3 vs 84.8 mg/dL), and systolic blood pressure (SBP) (104.6 vs 111.8 mm Hg). TG, TC and LDL-C were significantly higher in postmenopausal group (55.7 vs 101.8 mg/dL, P = .01; 158.3 vs 191.6 mg/dL, P = .04; 94.7 vs 118.2 mg/dL, P = .04). CONCLUSIONS: The findings from this study suggest that postmenopausal women with SCI have CMR trends similar to those observed in nondisabled women, characterized by increases in TG, TC, and LDL-C despite favorable BMIs and glycemic indices. Even though the present study includes significant limitations, future evidence may also suggest that heightened surveillance and guideline-driven interventions are indicated for perimenopausal and postmenopausal women with SCI.

RESUMEN

BACKGROUND: Despite growing evidence suggesting racial or ethnic disparities in the risk of severe maternal morbidity among live births, there is little research investigating potential differences in severe maternal morbidity risk among stillbirths across race and ethnicity. OBJECTIVE: This study aimed to compare the risk of severe maternal morbidity by race and ethnicity among patients with singleton stillbirth pregnancies. STUDY DESIGN: We used the California Linked Birth File database to perform a retrospective analysis of singleton stillbirth pregnancies delivered at 20 to 42 weeks' gestation between 2007 and 2011. The database contained information from fetal death certificates linked to maternal hospital discharge records. We defined severe maternal morbidity using the Centers for Disease Control and Prevention composite severe maternal morbidity indicator and compared rates of severe maternal morbidity across racial and ethnic groups. Multivariable regression analysis was used to examine how race and ethnicity were associated with severe maternal morbidity risk after accounting for the influence of patients' clinical risk factors, socioeconomic characteristics, and attributes of the delivery hospital. RESULTS: Of the 9198 patients with singleton stillbirths, 533 (5.8%) experienced severe maternal morbidity. Non-Hispanic Black patients had a significantly higher risk of severe maternal morbidity (10.6% vs 5.2% in non-Hispanic White patients, 5.2% in Hispanic patients, and 5.1% in patients with other race or ethnicity; P<.001). The higher risk of severe maternal morbidity among non-Hispanic Black patients persisted even after adjusting for patients' clinical, socioeconomic, and hospital characteristics (adjusted odds ratio for non-Hispanic Black vs non-Hispanic White patients, 1.74; 95% confidence interval, 1.21-2.50). Further analysis separating blood-transfusion and nontransfusion severe maternal morbidity showed a higher risk of blood transfusion in non-Hispanic Black patients, which remained significant after adjusting for patients' clinical, socioeconomic, and hospital characteristics (adjusted odds ratio for non-Hispanic Black vs non-Hispanic White patients, 1.64; 95% confidence interval, 1.11-2.43). However, the higher risk of nontransfusion severe maternal morbidity in non-Hispanic Black patients was no longer significant after adjusting for patients' clinical risk factors (adjusted odds ratio for non-Hispanic Black vs non-Hispanic White patients, 1.38; 95% confidence interval, 0.83-2.30). CONCLUSION: Severe maternal morbidity occurred in 5.8% of patients with a singleton stillbirth. Risk of severe maternal morbidity in stillbirth was higher in patients with non-Hispanic Black race, which was likely owing to a higher risk of hemorrhage, as evidenced by increased rate of blood transfusion.

RESUMEN

BACKGROUNDThe effects of the novel coronavirus disease 2019 (COVID-19) in pregnancy remain relatively unknown. We present a case of second trimester pregnancy with symptomatic COVID-19 complicated by severe preeclampsia and placental abruption.METHODSWe analyzed the placenta for the presence of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) through molecular and immunohistochemical assays and by and electron microscopy and measured the maternal antibody response in the blood to this infection.RESULTSSARS-CoV-2 localized predominantly to syncytiotrophoblast cells at the materno-fetal interface of the placenta. Histological examination of the placenta revealed a dense macrophage infiltrate, but no evidence for the vasculopathy typically associated with preeclampsia.CONCLUSIONThis case demonstrates SARS-CoV-2 invasion of the placenta, highlighting the potential for severe morbidity among pregnant women with COVID-19.FUNDINGBeatrice Kleinberg Neuwirth Fund and Fast Grant Emergent Ventures funding from the Mercatus Center at George Mason University.

RESUMEN

BACKGROUND Acute transverse myelitis (ATM) is an uncommon and often overlooked complication of certain bacterial and viral infections that can have a rapid onset and result in severe neurological deficits.  CASE REPORT This case report describes a previously healthy 28-year-old woman who presented to the trauma center after developing acute paralysis and paresthesias of all four extremities within the span of hours. The initial presumptive diagnosis was spinal cord contusion due to a fall versus an unknown mechanism of trauma, but eventual laboratory studies revealed Salmonella bacteremia, indicating a probable diagnosis of parainfectious ATM. CONCLUSIONS This case illustrates the importance of considering the diagnosis of parainfectious ATM in patients presenting with acute paralysis with incomplete or unobtainable medical histories.

RESUMEN

Recent preclinical studies have identified three treatments that are especially promising for reducing acute lesion expansion following traumatic spinal cord injury (SCI): riluzole, systemic hypothermia, and glibenclamide. Each has demonstrated efficacy in multiple studies with independent replication, but there is no way to compare them in terms of efficacy or safety, since different models were used, different laboratories were involved, and different outcomes were evaluated. Here, using a model of lower cervical hemicord contusion, we compared safety and efficacy for the three treatments, administered beginning 4 h after trauma. Treatment-associated mortality was 30% (3/10), 30% (3/10), 12.5% (1/8), and 0% (0/7) in the control, riluzole, hypothermia, and glibenclamide groups, respectively. For survivors, all three treatments showed overall favorable efficacy, compared with controls. On open-field locomotor scores (modified Basso, Beattie, and Bresnahan scores), hypothermia- and glibenclamide-treated animals were largely indistinguishable throughout the study, whereas riluzole-treated rats underperformed for the first two weeks; during the last four weeks, scores for the three treatments were similar, and significantly different from controls. On beam balance, hypothermia and glibenclamide treatments showed significant advantages over riluzole. After trauma, rats in the glibenclamide group rapidly regained a normal pattern of weight gain that differed markedly and significantly from that in all other groups. Lesion volumes at six weeks were: 4.8±0.7, 3.5±0.4, 3.1±0.3 and 2.5±0.3 mm(3) in the control, riluzole, hypothermia, and glibenclamide groups, respectively; measurements of spared spinal cord tissue confirmed these results. Overall, in terms of safety and efficacy, systemic hypothermia and glibenclamide were superior to riluzole.
