At-home urine pregnancy test assessment after mifepristone and misoprostol for undesired pregnancy of unknown location.

OBJECTIVES: The ideal assessment after mifepristone and misoprostol for undesired pregnancy of unknown location (PUL) is unknown. STUDY DESIGN: We prospectively followed patients at Planned Parenthood League of Massachusetts (2019-2021) with PUL who received immediate mifepristone and misoprostol with serial at-home urine pregnancy tests (UPT) and in-office serum HCGs. RESULTS: Of 13 patients, 10 had a successful medication abortion. For those who completed UPTs (N = 9), all were negative by Day 14. Two abnormal pregnancies had positive UPTs on Day 14. CONCLUSION: A negative UPT on Day 14 may help determine complete abortion after medication abortion for undesired PUL. A positive UPT on Day 14 warrants further evaluation. IMPLICATION: Patients taking mifepristone and misoprostol in the setting of undesired PUL who cannot access serum testing may consider an at-home UPT to confirm complete abortion.

Obesity downregulates lipid metabolism genes in first trimester placenta.

Placentas of obese women have low mitochondrial ß-oxidation of fatty acids (FA) and accumulate lipids in late pregnancy. This creates a lipotoxic environment, impairing placental efficiency. We hypothesized that placental FA metabolism is impaired in women with obesity from early pregnancy. We assessed expression of key regulators of FA metabolism in first trimester placentas of lean and obese women. Maternal fasting triglyceride and insulin levels were measured in plasma collected at the time of procedure. Expression of genes associated with FA oxidation (FAO; ACOX1, CPT2, AMPKα), FA uptake (LPL, LIPG, MFSD2A), FA synthesis (ACACA) and storage (PLIN2) were significantly reduced in placentas of obese compared to lean women. This effect was exacerbated in placentas of male fetuses. Placental ACOX1 protein was higher in women with obesity and correlated with maternal circulating triglycerides. The PPARα pathway was enriched for placental genes impacted by obesity, and PPARα antagonism significantly reduced 3H-palmitate oxidation in 1st trimester placental explants. These results demonstrate that obesity and hyperlipidemia impact placental FA metabolism as early as 7 weeks of pregnancy.

Mifepristone and Misoprostol for Undesired Pregnancy of Unknown Location.

OBJECTIVE: To compare immediate initiation with delayed initiation of medication abortion among patients with an undesired pregnancy of unknown location. METHODS: This retrospective cohort study used electronic medical record data from the Planned Parenthood League of Massachusetts (2014-2019) for patients who requested medication abortion with a last menstrual period (LMP) of 42 days or less and pregnancy of unknown location (no gestational sac) on initial ultrasonogram. Clinicians could initiate medication abortion with mifepristone followed by misoprostol while simultaneously excluding ectopic pregnancy with serial serum human chorionic gonadotropin (hCG) testing (same-day-start group) or establish a diagnosis with serial hCG tests and repeat ultrasonogram before initiating treatment (delay-for-diagnosis group). We compared primary safety outcomes (time to diagnosis of pregnancy location [rule out ectopic], emergency department visits, adverse events, and nonadherence with follow-up) between groups. We also reported secondary efficacy outcomes: time to complete abortion, successful medication abortion (no uterine aspiration), and ongoing pregnancy. RESULTS: Of 5,619 medication abortion visits for patients with an LMP of 42 days or less, 452 patients had pregnancy of unknown location (8.0%). Three patients underwent immediate uterine aspiration, 55 had same-day start, and 394 had delay for diagnosis. Thirty-one patients (7.9%), all in the delay-for-diagnosis group, were treated for ectopic pregnancy, including four that were ruptured. Among patients with no major ectopic pregnancy risk factors (n=432), same-day start had shorter time to diagnosis (median 5.0 days vs 9.0 days; P=.005), with no significant difference in emergency department visits (adjusted odds ratio [aOR] 0.90, 95% CI 0.43-1.88) or nonadherence with follow-up (aOR 0.92, 95% CI 0.39-2.15). Among patients who proceeded with abortion (n=270), same-day start had shorter time to complete abortion (median 5.0 days vs 19.0 days; P<.001). Of those who had medication abortion with known outcome (n=170), the rate of successful medication abortion was lower (85.4% vs 96.7%; P=.013) and the rate of ongoing pregnancy was higher (10.4% vs 2.5%; P=.041) among patients in the same-day-start group. CONCLUSION: In patients with undesired pregnancy of unknown location, immediate initiation of medication abortion is associated with more rapid exclusion of ectopic pregnancy and pregnancy termination but lower abortion efficacy.

The Use of Feticidal Agents Before Dilation and Evacuation or Induction of Labor for Later Abortion.

Abortion is a common medical procedure in the United States that is frequently the target of political and legal restrictions. These restrictions can negatively impact care and interfere with the patient-provider relationship. In this paper, we aim to review the historic context in which feticidal agents became more utilized in later abortion; describe current practices and protocols of using feticidal agents use for later abortion by dilation and evacuation and induction of labor; evaluate patient and provider perspectives on feticidal agent use; and propose areas of further ethical and research inquiry to characterize the use of these agents in later abortion procedures.

Label-free, High-Resolution Optical Metabolic Imaging of Human Cervical Precancers Reveals Potential for Intraepithelial Neoplasia Diagnosis.

While metabolic changes are considered a cancer hallmark, their assessment has not been incorporated in the detection of early or precancers, when treatment is most effective. Here, we demonstrate that metabolic changes are detected in freshly excised human cervical precancerous tissues using label-free, non-destructive imaging of the entire epithelium. The images rely on two-photon excited fluorescence from two metabolic co-enzymes, NAD(P)H and FAD, and have micron-level resolution, enabling sensitive assessments of the redox ratio and mitochondrial fragmentation, which yield metrics of metabolic function and heterogeneity. Simultaneous characterization of morphological features, such as the depth-dependent variation of the nuclear:cytoplasmic ratio, is demonstrated. Multi-parametric analysis combining several metabolic metrics with morphological ones enhances significantly the diagnostic accuracy of identifying high-grade squamous intraepithelial lesions. Our results motivate the translation of such functional metabolic imaging to in vivo studies, which may enable improved identification of cervical lesions, and other precancers, at the bedside.

Moderate intravenous sedation for first trimester surgical abortion: a comparison of adverse outcomes between obese and normal-weight women.

OBJECTIVE: To determine if obese women experience increased rates of adverse outcomes with moderate intravenous sedation during first trimester surgical abortion compared to normal weight women. STUDY DESIGN: We performed a retrospective cohort study of all first trimester surgical abortions with moderate intravenous sedation at an outpatient facility between September 2010 and June 2015. The primary outcome was supplemental oxygen administration. Secondary outcomes included reversal agent administration, anesthesia-related adverse events, and intraoperative lowest level of consciousness (LLOC). We compared three obesity groups [I (Body Mass Index, BMI=30-34.9), II (BMI=35-39.9), and III (BMI ≥40)] to normal weight women (BMI <25). We exported data from electronic medical records and reviewed adverse outcomes individually. RESULTS: Of 20,381 first trimester surgical abortion procedures, 31 (0.15%) utilized supplemental oxygen, 24 (0.12%) utilized a reversal agent, 40 (0.20%) had a presumed anesthesia-related adverse event and 184 of 19,725 (0.93%) had a documented low intraoperative LLOC. One patient (0.005%) required hospital transfer or hospitalization. Supplemental oxygen administration (obesity versus normal weight: obese I, aOR 0.52, 95% CI 0.12-2.27; II/III, aOR 1.51, 95% CI 0.50-4.54), low intraoperative LLOC, and anesthesia-related adverse events were not associated with obesity. The rate of reversal agent administration was lower among obese I, II and III women combined compared to normal weight women (aOR 0.13, 95% CI 0.02-0.96). CONCLUSIONS: Adverse outcomes were rare across all BMI categories with no detectable increased risk among obese women compared to normal weight women. IMPLICATIONS: With appropriate clinical screening, obese women can safely receive moderate intravenous sedation for first trimester surgical abortion in an outpatient clinical setting. Restrictions on moderate intravenous sedation based on BMI alone may be unnecessary.

Long-acting reversible contraceptives for teenagers: primary care recommendations.

Long-acting reversible contraceptive (LARC) methods are underutilized in the adolescent population despite their superior efficacy over non-LARC methods. The purpose of this article is to discuss the barriers that lead to underutilization of these methods and present an evidence-based approach for the use of LARC methods among adolescents in the primary care setting.

Inflammation or infection at the time of second trimester induced abortion.

BACKGROUND: Induced abortion via dilation and evacuation (D&E) typically involves cervical preparation. Some clinicians also induce fetal death in the second trimester. We designed this study to determine if the combination of intra-amniotic digoxin and osmotic dilators induced intrauterine inflammatory changes. STUDY DESIGN: Twenty-two women requesting abortion at 19-23 weeks gestation had amniotic fluid sent for measurement of interleukin-6 (IL-6), interleukin-8 (IL-8), tumor necrosis factor-α (TNF-α), white blood cell (WBC) count and anaerobic and aerobic cultures on day 1, before dilators and digoxin amnioinjection. Sampling was repeated on Day 2, prior to D&E. RESULTS: All subjects had significantly elevated IL-6, IL-8 and TNF-α in the amniotic fluid on Day 2. The median difference for IL-6 was 19,893.4 pg/mL (p<.0001), 7040.7 pg/mL (p<.0001) for IL-8 and 181.0 pg/mL (p<.0001) for TNF-α. There was no significant difference in WBC count. There were no clinically significant positive cultures and no clinical infections. CONCLUSION: The administration of intra-amniotic digoxin and the placement of osmotic dilators prior to D&E create an intrauterine inflammatory response.

Mifepristone vs. osmotic dilator insertion for cervical preparation prior to surgical abortion at 14-16 weeks: a randomized trial.

BACKGROUND: Cervical preparation is recommended before second-trimester abortion. We investigated the use of a pharmacologic method of preparation, mifepristone, as compared to osmotic dilators for surgical abortions at 14-16 weeks. STUDY DESIGN: This was a randomized, parallel-group study with concealed allocation. Women were allocated to receive osmotic dilators or mifepristone 200 mg orally 24 h prior to abortion. The study population was 50 women seeking surgical abortion at 14-16 menstrual weeks in a hospital-based abortion service. The primary outcome was the length of time to perform the procedure; the study had 80% power to detect a difference of more than 3 min in procedure time. Secondary outcomes included cervical dilation, side effects and acceptability. RESULTS: The mean abortion time for the osmotic dilator group was 8.00 min [95% confidence interval (CI) 6.75-11.47], and that for the mifepristone group was 9.87 min (95% CI 8.93-11.36). Side effects of pain were more common in the osmotic dilator group. CONCLUSION: Mifepristone did not increase the time for abortion by more than the prespecified margin (3 min). Women preferred mifepristone to osmotic dilators.
