Health services provided at the time of abortion in the US: a scoping review of the qualitative and quantitative evidence.

Objectives: While it is well documented that abortion access is associated with improved health, pregnancy-related, and socioeconomic outcomes, the association between abortion access and other reproductive health outcomes is less well described. Abortion-providing clinics also offer preventative reproductive health services. We conducted a scoping review to ascertain the extent to which preventive reproductive healthcare services (contraception, sexually transmitted infection testing and treatment, cervical cancer screening) are affected by abortion access in the United States. Methods: Researchers screened articles and extracted data from PubMed, Embase, Scopus and CINAHL. We excluded articles that did not link abortion to contraception, sexually transmitted infection testing and treatment and cervical cancer screening; or took place outside the US. Results: 5,359 papers were screened, 74 were included for full text review. Sixty-five were about contraception, seven on STIs, one on cervical cancer screening, and one on other services. The association between policies that restrict or protect abortion access and preventative health services has not been studied on a national scale. Drivers of variation were: insurance and billing policies; regulatory requirements of abortion-providing facilities, lack of staff training in clinics that did not specialize in abortion care; and limited follow up after abortion. Conclusions: Abortion--providing clinics are a highly utilized access point for reproductive health services. More research is needed to determine the public health impact of constrained abortion access on contraceptive use, STI rates and cervical cancer in regions where many abortion-providing clinics have closed. Implications: Attention should be paid to changing trends in contraceptive use, STI rates and cervical cancer as abortion-providing clinics close, this may reduce access to reproductive health services broadly.

State restrictions on abortion are associated with fewer abortions in patients with high-risk cardiovascular conditions.

OBJECTIVES: Patients with modified World Health Organization (mWHO) class IV cardiovascular conditions are at high risk of severe maternal morbidity and mortality in pregnancy and are advised to avoid pregnancy or consider abortion if they become pregnant. We aimed to determine if state-level abortion policy is associated with receiving an abortion in this high-risk population. STUDY DESIGN: We conducted a descriptive retrospective cross-sectional study of abortion among people 15-44 years of age with mWHO class IV cardiovascular conditionsstate policy on abortion using US claims data from United health Group from 2017 to 2020. RESULTS: There was a statistically significant association between restrictive abortion policy at that state level and lower number of pregnancies ending in abortions in this high-risk group. CONCLUSIONS: States with the most restrictive abortion policy have the lowest proportion of pregnancies ending in abortion among patients with mWHO class IV cardiovascular conditions. IMPLICATIONS: Variation in receiving abortion by state of residence among patients with mWHO class IV cardiovascular conditions may indicate an impending rise in severe maternal morbidity and mortality related to cardiovascular disease in pregnancy, and the risk factor is where a person lives. This trend may be exacerbated by the Supreme Court Decision Dobbs v Jackson Women's Health.

Utility and Limitations of Human Chorionic Gonadotropin Levels for Remote Follow-up After Medical Management of Early Pregnancy Loss.

Early pregnancy loss can be treated medically with mifepristone followed by misoprostol, with ultrasonographic confirmation of pregnancy expulsion. Alternative strategies that ascertain treatment success remotely are needed. We compared percent decline in human chorionic gonadotropin (hCG) level with treatment success or failure between patients who received mifepristone pretreatment followed by misoprostol or misoprostol alone for early pregnancy loss between 5 and 12 weeks of gestation to determine a threshold decline that might predict success. Early pregnancy loss treatment success was associated with a greater percent hCG level decline compared with treatment failure, but no threshold was able to predict success. Additional research is needed to understand hCG trends after medical management of early pregnancy loss to develop reliable protocols for remote follow-up.

Pregnant and bleeding: A model to assess factors associated with the need for emergency care in early pregnancy.

OBJECTIVE: To assess the prevalence of Critical or Emergent patient classification among pregnant patients presenting to the Emergency Department (ED) and to identify characteristics that discriminate between patients requiring Emergency care from those who can be safely triaged to the ambulatory setting. STUDY DESIGN: In this cross-sectional study conducted in 3 urban EDs, patients under 16 weeks gestation who presented with bleeding and/or cramping completed a 7-item questionnaire. We compared baseline clinical variables and survey responses among patients classified as Critical or Emergent per the American Board of Emergency Medicine's patient acuity definitions with those classified as Lower Acuity to identify independent risk factors for outcomes. RESULTS: Of 484 participants, 21 (4.3%) were classified as Critical or Emergent and required interventions. While no demographic characteristics differentiated Critical patients from Lower Acuity patients, survey questions associated with a higher likelihood of emergency intervention included history of prior ectopic pregnancy (OR 8.7, 95% CI 3.2-23.5) heavy bleeding in the past two hours (OR 11.8, 95% CI 3.8-36.1), as well as having made a prior ED visit in the current pregnancy (OR 1.9, 95% CI 0.7-5.1). Joint consideration of these risk factors in a multivariable model performed well at discriminating between Critical and Lower Acuity patients with an area under the ROC curve of 0.82 (95% CI 0.71-0.93). CONCLUSION: Patients with a history of ectopic pregnancy, heavy bleeding in the past two hours, and/or prior presentation to the ED in the current pregnancy had the highest risk of needing emergency-level care. The vast majority of patients presenting to the ED with early pregnancy complaints were discharged without intervention.

Transient Fetal Tachycardia After Intravenous Diphenhydramine Administration.

BACKGROUND: Fetal tachycardia is attributable to a variety of etiologies, including an untreated maternal medical condition or an indicator of potential fetal compromise. Maternal medication administration may also affect the fetal heart rate. CASE: A 28-year-old nulliparous patient at 41 weeks of gestation was treated for pruritus with intravenous diphenhydramine after epidural administration of fentanyl. Within 14 minutes, the fetal heart rate increased from a baseline of 155 beats per minute (bpm) to more than 200 bpm while maintaining moderate variability. This was accompanied by an increase in uterine contractions occurring every 1.5 minutes. The fetal tachycardia lasted 51 minutes; several hours later, a healthy neonate was delivered. CONCLUSION: Diphenhydramine may produce transient fetal tachycardia as well as increased maternal uterine activity.

Dynamic molecular monitoring of retina inflammation by in vivo Raman spectroscopy coupled with multivariate analysis.

Retinal tissue is damaged during inflammation in Multiple Sclerosis. We assessed molecular changes in inflamed murine retinal cultures by Raman spectroscopy. Partial Least Squares-Discriminant analysis (PLS-DA) was able to classify retina cultures as inflamed with high accuracy. Using Multivariate Curve Resolution (MCR) analysis, we deconvolved 6 molecular components suffering dynamic changes along inflammatory process. Those include the increase of immune mediators (Lipoxygenase, iNOS and TNFα), changes in molecules involved in energy production (Cytochrome C, phenylalanine and NADH/NAD+) and decrease of Phosphatidylcholine. Raman spectroscopy combined with multivariate analysis allows monitoring the evolution of retina inflammation.

A benchmark for chromatin binding measurements in live cells.

Live-cell measurement of protein binding to chromatin allows probing cellular biochemistry in physiological conditions, which are difficult to mimic in vitro. However, different studies have yielded widely discrepant predictions, and so it remains uncertain how to make the measurements accurately. To establish a benchmark we measured binding of the transcription factor p53 to chromatin by three approaches: fluorescence recovery after photobleaching (FRAP), fluorescence correlation spectroscopy (FCS) and single-molecule tracking (SMT). Using new procedures to analyze the SMT data and to guide the FRAP and FCS analysis, we show how all three approaches yield similar estimates for both the fraction of p53 molecules bound to chromatin (only about 20%) and the residence time of these bound molecules (∼1.8 s). We also apply these procedures to mutants in p53 chromatin binding. Our results support the model that p53 locates specific sites by first binding at sequence-independent sites.
