Hiding in Plain Sight: Resident Remediation in Obstetrics and Gynecology.

OBJECTIVE: Residents who are in need of remediation are prevalent across residency programs and often tend to be deficient in multiple competencies that the American Council for Graduate Medical Education (ACGME) has established. The purpose of this study was to determine the prevalence of residents requiring remediation, understand the scope of the challenges in resident remediation, and assess what resources were used to aid in remediation in obstetrics and gynecology programs. DESIGN: An anonymous survey was emailed to obstetrics and gynecology program directors. Survey responses were summarized through descriptive statistics. SETTING: Obstetrics and gynecology residency program directors were invited to respond to this survey. PARTICIPANTS: Thirty-nine respondents out of 241 residency training programs responded (16%). RESULTS: The majority (84.6%) of programs had placed a resident on remediation. The most common area requiring remediation was professionalism (75.8%), followed by medical knowledge (72.7%), interpersonal communication (60.6%), laparoscopic technical skills (54.6%), and inpatient care (42.4%). Residents who required remediation were identified in a number of ways, most commonly through feedback from the Clinical Competency Committee (87.8%) and faculty feedback (84.8%). Program directors utilized a variety of resources, most commonly prior remediation plans from the program, to create remediation plans. Sixty percent of programs had residents who failed remediation. CONCLUSION: This study highlighted the prevalence of resident remediation in obstetrics and gynecology training programs and the importance of faculty in identifying residents in need of remediation, evaluating residents, and mentoring residents.

A Novel Dual-Function Nitric Oxide Donor Therapy for Preeclampsia-A Proof-of-Principle Study in a Murine Model.

Background: Preeclampsia (PE) is a hypertensive disorder of pregnancy that is associated with substantial morbidity and mortality for the mother and fetus. Reduced nitric oxide bioavailability and oxidative stress contribute to the maternal and fetal pathophysiology of PE. In this study, we evaluated the efficacy of a novel dual-function nitric oxide donor/redox modulator, AKT-1005, in reducing PE symptoms in a mouse model of PE. Method: The potential therapeutic effect of AKT-1005 was tested in an animal model of Ad.sFlt-1-induced hypertension, proteinuria and glomerular endotheliosis, a model of PE. Pregnant Ad.sFlt-1-overexpressing CD1 mice were randomized into groups administered AKT-1005 (20 mg/kg) or a vehicle using a minipump on gd11 of pregnancy, and the impact on blood pressure and renal and placental damage were assessed. Results: In healthy female mice, ex vivo treatment of resistance vessels with AKT-1005 induced vasorelaxation, and 6 days of treatment in vivo did not significantly alter blood pressure with or without pregnancy. When given for 6 days during pregnancy along with Ad.sFlt-1-induced PE, AKT-1005 significantly increased plasma nitrate levels and reduced hypertension, renal endotheliosis and plasma cystatin C. In the placenta, AKT-1005 improved placental function, with reduced oxidative stress and increased endothelial angiogenesis, as measured by CD31 staining. As such, AKT-1005 treatment attenuated the Ad.sFlt-1-induced increase in placental and free plasma soluble endoglin expression. Conclusions: These data suggest that AKT-1005 significantly attenuates the sFlt-1-induced PE phenotypes by inhibiting oxidative stress, the anti-angiogenic response, and increasing NO bioavailability. Additional research is warranted to investigate the role of AKT-1005 as a novel therapeutic agent for vascular disorders such as preeclampsia.

A Novel Dual-Function Redox Modulator Relieves Oxidative Stress and Anti-Angiogenic Response in Placental Villus Explant Exposed to Hypoxia-Relevance for Preeclampsia Therapy.

BACKGROUND: Preeclampsia (PE) is a severe, life-threatening complication during pregnancy (~5-7%), and no causative treatment is available. Early aberrant spiral artery remodeling is associated with placental stress and the release of oxygen radicals and other reactive oxygen species (ROS) in the placenta. This precedes the production of anti-angiogenic factors, which ultimately leads to endothelial and trophoblast damage and the key features of PE. We tested whether a novel dual-function redox modulator-AKT-1005-can effectively reduce placental oxidative stress and alleviate PE symptoms in vitro. METHOD: Isolated human villous explants were exposed to hypoxia and assessed to determine whether improving cell-redox function with AKT-1005 diminished ROS production, mitochondrial stress, production of the transcription factor HIF1A, and downstream anti-angiogenic responses (i.e., sFLT1, sEng production). MitoTEMPO was used as a reference antioxidant. RESULTS: In our villous explant assays, pretreatment with AKT-1005 reduced mitochondrial-derived ROS production, reduced HIF-1A, sFLT1, and sEng protein expression, while increasing VEGF in hypoxia-exposed villous trophoblast cells, with better efficiency than MitoTEMPO. In addition, AKT-1005 improved mitochondrial electron chain enzyme activity in the stressed explant culture. CONCLUSIONS: The redox modulator AKT-1005 has the potential to intervene with oxidative stress and can be efficacious for PE therapy. Future studies are underway to assess the in vivo efficacy of HMP.

Antenatal Optimization of Maternal Anemia Leads to Decreased Risks of Maternal Morbidity.

Purpose of Review: Our review focuses on the appropriate use of intravenous iron to increase the likelihood of achieving target hemoglobin levels prior to delivery to reduce maternal morbidity. Recent Findings: Iron deficiency anemia (IDA) is a leading contributor to severe maternal morbidity and mortality. Prenatal treatment of IDA has been demonstrated to reduce the likelihood of adverse maternal outcomes. Recent investigations of intravenous iron supplementation have demonstrated superior efficacy and high tolerability for the treatment of IDA in the third trimester, compared against oral regimens. However, it is unknown whether this treatment is cost-effective, available to clinicians, or acceptable to patients. Summary: Intravenous iron is superior to the oral treatment of IDA; however, its use is limited by the lack of implementation data.

Collaboration between Maternal-Fetal Medicine and Neonatology When Counseling at Extreme Prematurity.

Enhanced communication between maternal-fetal medicine (MFM)/obstetrics and neonatology regarding counseling at extreme prematurity remains an essential element of prenatal consultations. Together, the obstetrician and neonatologist can collaborate to provide timely and synergistic information to affected couples during a dynamic period, combining their expertise to elucidate values and formulate a plan that best supports the pregnant person and partner's goals. Such collaboration can help resolve differing perspectives between specialties, minimize redundancy and inconsistencies, and mitigate the impact of clinician bias. Best practices for joint-specialty collaboration include a precounseling clinician huddle, contemporaneous counseling by MFM specialists/obstetricians and neonatologists with the expectant parents or individualized sequential counseling if preferred by the couple, and a postcounseling clinician debrief. This approach can help establish a trusting relationship with families facing possible extremely preterm delivery and optimize the overall counseling experience. Future efforts focused on education and research, including a standardized approach to educational curricula among fellowship programs, should be emphasized.

PCOS and the risk of pre-eclampsia.

RESEARCH QUESTION: What is the association between polycystic ovary syndrome (PCOS) and pre-eclampsia? Data suggest that patients with PCOS are at increased risk of developing pre-eclampsia; however, several studies have not found an independent association between the two. DESIGN: A retrospective case-control study of singleton deliveries at a tertiary care hospital from 2011 to 2015. Patients with pre-eclampsia (cases) were matched to the next delivery without pre-eclampsia (controls) on gestational age week. Medical history data, a diagnosis or clinical features of PCOS and obstetric data, including pre-eclampsia, were abstracted from the medical record. Groups were compared with the chi-squared test, and conditional logistic regression was used to calculate odds ratios (OR) and 95% confidence intervals (95% CI). OR were adjusted for maternal age at delivery and race/ethnicity. RESULTS: This study included 435 cases and 435 controls. Cases were more likely to be Black compared with controls. Age, comorbidities, features of PCOS and use of IVF were similar between groups. Patients with pre-eclampsia were not more likely to have PCOS (8.3%) than those without pre-eclampsia (6.2%, adjusted OR 1.40, 95% CI 0.81-2.30). Sensitivity analyses for body mass index and parity suggested an increased pre-eclampsia risk for patients with PCOS and these additional factors, however no group showed a statistically significant association between PCOS and pre-eclampsia. CONCLUSIONS: In this study, a history of PCOS was not associated with the risk of pre-eclampsia. Further investigation is necessary to determine whether there are subgroups of PCOS patients who are at increased risk of pre-eclampsia.

Hypertensive Disorders of Pregnancy.

Preeclampsia is a hypertensive disorder of pregnancy that is a leading cause of maternal and perinatal morbidity and mortality. The condition presents heterogeneously at varying gestational ages. Primary prevention for preeclampsia with low-dose aspirin is recommended for patients with clinical risk factors. Despite extensive research, there is no clearly defined pathophysiology for preeclampsia or treatment for preeclampsia besides delivery of the placenta. Delivery of patients with preeclampsia without severe features is indicated in the early term period at 37 weeks' gestation and sooner if the patient develops severe preeclampsia. Management of preterm preeclampsia is guided by close assessment of the status of the pregnant woman and fetus, blood pressure control, and surveillance for any clinical progression to a more severe form of preeclampsia that may require preterm delivery. In a preterm gestation affected by preeclampsia, expectant management is intended to provide neonatal benefit though it does assume some maternal risk. Future research will hopefully further delineate the pathophysiology of the condition with the ultimate goal of finding a treatment to avoid associated morbidity and preterm delivery.

Angiogenic factors and prediction for ischemic placental disease in future pregnancies.

OBJECTIVES: Ischemic placental disease (IPD), including preeclampsia, abruption, and fetal growth restriction, often recurs in subsequent pregnancies. Angiogenic factors of placental origin have been implicated in the pathogenesis of preeclampsia, but have not been studied as predictors of IPD in subsequent pregnancies. We hypothesized that elevated angiogenic factors in an index pregnancy would be associated with recurrence of IPD. STUDY DESIGN: We conducted a retrospective cohort study of patients undergoing evaluation for preeclampsia who had angiogenic factors measured in an index pregnancy and experienced a subsequent pregnancy at the same institution. Patients with IPD in the index pregnancy were included. A high ratio of soluble fms-like tyrosine kinase 1 (sFlt1) and placental growth factor (PlGF) was defined as greater than or equal to 85. MAIN OUTCOME MEASURES: The primary outcome was IPD in a subsequent pregnancy. RESULTS: We included 109 patients in the analysis. The sFlt1/PlGF ratio was elevated in 30% of participants. Those with an elevated ratio were more likely to be nulliparous in the index pregnancy, and less likely to have chronic hypertension. The recurrence of IPD in the study was 27%, with a non-significant difference in risk based on a high sFlt-1/P1GF ratio RR 0.58 (95% CI 0.21 - 1.6) compared to a low ratio. CONCLUSIONS: A high sFlt1/P1GF ratio in an index pregnancy is not associated with a higher risk of IPD in a subsequent pregnancy. These data suggest placental angiogenic biomarkers are specific to the pregnancy and not a reflection of maternal predisposition to IPD.
