Purpose Of Review: To review emerging evidence specific to abortion care, including diagnostic testing and pain management.
Recent Findings: Recent advances in abortion care include improvements in gestational age dating, Rh status testing, and pain management methods. When ultrasound technology is available, the use of crown-rump length (CRL)-based dating is more accurate up to 13 weeks and composite CRL and biometry between 13 and 14 weeks. Evidence supports using updated fetal foot length-to-gestational age reference ranges for postprocedure gestational age confirmation. Serum tests for two placental proteins, pregnancy-associated plasma protein A and a disintegrin and metalloproteinase 12, show potential for identifying pregnancies with gestational age more than 70 days. Early research using flow cytometry demonstrates that fetal RBC exposure after first-trimester uterine aspiration is insufficient to cause maternal Rh-sensitization, supporting elimination of Rh testing and anti-D-immunoglobulin provision prior to 8 weeks gestation. Recent studies exploring pain management strategies have not generated a standardized approach. Auricular acupuncture appears to be promising.
Summary: Emerging data on improvements in gestational age dating and eliminating laboratory testing prior to early abortion procedures could have important implications for expanding access to early abortion care and telemedicine. Person-centered, novel pain management modalities, such as auricular acupuncture, help to improve client experience, by addressing both pain and anxiety.

School of Nursing and Midwifery, Western Sydney University.
This article examines whether the current termination laws of Australia and Aotearoa New Zealand align with the midwifery scope of practice. It begins with an introduction to termination of pregnancy from a health care perspective. An overview of previous and current legal frameworks in Australia and Aotearoa New Zealand that impact upon the provision of termination of pregnancy health services is provided.

Objective: We explored awareness of and attitudes about the safety of various methods people use to attempt to end a pregnancy without medical assistance, which we refer to in this study collectively as self-managed abortion (SMA).
Methods: In 2020, we invited individuals living in eight United States (US) states considered "hostile" to abortion rights or with a history of criminalizing abortions performed outside the formal healthcare system to participate in semi-structured telephone interviews regarding their attitudes toward these practices. We analyzed coded transcripts for content and themes.
Public hospital-based care for abortive events in Mexico: complication rates and socio-demographic factors, 2018-2022.
BMC Public Health

OHSU-PSU School of Public Health, 1805 SW 4th Avenue, Portland, OR, 97201, USA.
Background: Abortion-related complications are difficult to measure due to lack of standardized definitions and limited available data. We describe the proportion of abortive events that result in a documented complication in Mexico's public sector hospitals.
Methods: We used ICD-10 codes from Mexico's hospital discharge system (2018-2022), Subsistema Automatizado de Egresos Hospitalarios (SAEH), to describe abortive events admitted to hospitals: complications for excessive bleeding, infection, embolism, and unspecified; patient socio-demographic and clinical characteristics; and municipality-level structural vulnerability.

Recurrent miscarriage (RM) is a reproductive disorder affecting couples worldwide. The underlying molecular mechanisms remain elusive, even though emerging evidence has implicated endoplasmic reticulum stress (ERS). We investigated RM- and ERS-related genes to develop a diagnostic model that can enhance predictive ability.

Objectives: Restrictive policies on abortion and gender-affirming care have increased in recent years, particularly in some Midwest states, and can have a disproportionate impact on young people. We sought to explore adolescent perspectives on such policies.
Study Design: We conducted virtual semistructured interviews with 39 participants aged 16 to 19 residing in the Midwest between April and June 2023, exploring participant reactions to state policies on abortion and gender-affirming care.
