Examination of women's emotions and feeling that abortion was the right decision over five years adds to the scientific evidence that emotions about an abortion are associated with personal and social context, and are not a product of the abortion procedure itself.

Abortion rates decreased from 2010 to 2019 for all women, regardless of age; however, abortion ratios in 2019 were highest among adolescents (aged ≤19 years) and lowest among women aged 25–39 years.

Abortion rates decreased from 2012 to 2021 among all age groups, except women aged 30–34 years for whom it increased, and abortion ratios increased among women aged 15–29 years and decreased among adolescents aged <15 years and women aged ≥30 years.

Most people considering abortion perceive some abortion stigma, which is associated with psychological distress years later, compared to those who obtained an abortion near a facility’s gestational age limit and carried their pregnancies to term.

The global unintended pregnancy rate has declined, whereas the proportion of unintended pregnancies ending in abortion has increased, and the global average abortion rate in 2015-19 was roughly equal to the estimates for 1990-94.

Despite being a defining issue in the culture war, the political psychology of abortion attitudes remains poorly understood. We address this oversight by reviewing existing literature and integrating new analyses of several large‐scale, cross‐sectional, and longitudinal datasets to identify the demographic and ideological correlates of abortion attitudes. Our review and new analyses indicate that abortion support is increasing modestly over time in both the United States and New Zealand. We also find that a plurality of respondents (43.8%) in the United States are consistently “pro‐choice,” wh...

The purpose of this document is to provide updated evidence-based guidance on the provision of medication abortion up to 70 days (or 10 weeks) of gestation.

The impact of the multiple interactions of various immune cells on the emergence of RSA is summarized, and a good understanding of pregnancy-induced immunological alterations could reveal new therapeutic strategies for favorable pregnancy outcomes.

Failures of safety-critical mission-based systems, such as aircraft and submarines, could result in significant losses and damage. To enhance the survivability of such systems, their missions may be aborted if the failure risk becomes too high. We investigate such mission abort policies under a completely observed two-stage degradation process that progresses stochastically from "normal" to "defective" to "failure." Mission abort decisions are considered as a function of the duration of the defective stage. This mission abort problem is formulated as a discrete-time optimal stopping problem wi...

The aim of this review is to discuss the medical and surgical approach to the management of RSA, including those caused by anatomical, genetic, male, infectious, endocrine, and immune factors, and to propose supportive treatment recommendations for patients with unclear causes.

The need for abortion care was growing just prior to the overturning Roe v. Wade, and the impact of this decision will be even more far‐reaching than previously expected.

This review summarizes the current knowledge on bacterial defense via cell suicide, describes the principles of Abi, details how these principles are implemented in a variety of natural defense systems, and discusses phage counter-defense mechanisms.

This paper investigates the joint optimization of inspection and condition based mission abort policies for systems subject to continuous degradation and numerically evaluates several heuristic policies where mission reliability and system survivability are derived.

Two threshold ECDSA protocols, for any number of signatories and any threshold, that improve as follows over the state of the art: -- For both protocols, only the last round requires knowledge of the message, and the other rounds can take place in a preprocessing stage, lending to a non-interactive threshold E CDSA protocol.

This study presents findings from case-control surveillance of COVID-19 vaccination during pregnancy and spontaneous abortion.

Restricting access to abortion care at the state level may increase the risk for TMM, and ecological state-level generalized linear Poisson regression models with robust standard errors are fit to estimate 4-year T MM, MM, and LMM rate ratios and 95% confidence intervals associated with a 1-unit increase in the abortion index.

It is reported that low embryonic villous succinate level associates with risk of RSA in patients, and increasing succinate levels is sufficient to reduce the incidence rate in a mouse model of spontaneous abortion.

Abortion during the Covid-19 Pandemic Governors in several states have categorized abortion procedures as “elective” or “nonessential” and have ordered a halt to most surgical abortions during the epidemic.

This paper investigates the condition based mission abort policies for systems subject to two-stage degradation process with normal and defective stages and compares the optimal policy against several heuristic policies where mission reliability and system survivability are evaluated.

This work investigates the optimal mission abort policies for systems subject to a controllable shock process with self-healing mechanism and finds that the optimal policy is to minimize the expected total cost of mission failure, system failure and imperfect repair.

This article designs mission abort policies based on two crucial information: degradation degree of monitored health features, and system age, which makes contribution by scheduling mission abort plans harnessing both condition monitoring and age information, which promotes the timeliness and robustness of risk control.

Abstract Individuals with potential exposure to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) do not necessarily develop PCR or antibody positivity, suggesting that some individuals may clear subclinical infection before seroconversion. T cells can contribute to the rapid clearance of SARS-CoV-2 and other coronavirus infections 1–3 . Here we hypothesize that pre-existing memory T cell responses, with cross-protective potential against SARS-CoV-2 (refs. 4–11 ), would expand in vivo to support rapid viral control, aborting infection. We measured SARS-CoV-2-reactive T cells, includ...

A type III TA system, toxIN, is characterized that protects E. coli against multiple bacteriophages, including T4, and blocks phage development primarily by cleaving viral mRNAs and inhibiting their translation.

Novel molecular mechanisms underlying DSCs autophagy-driven dNK cell residence are revealed, and a potential therapeutic strategy to prevent spontaneous abortion is provided.

SARS-CoV-2 infection during the first trimester of pregnancy does not appear to predispose to early pregnancy loss; its cumulative incidence did not differ between women with spontaneous abortion and women with ongoing pregnancy.

A Bayesian model was developed which jointly estimated unintended pregnancy and abortion rates using information on contraceptive needs and use, contraceptive method mix, birth rates, the proportions of births from unintended pregnancies and abortion incidence data, and between-country heterogeneity.

It is shown that retinoic acid–inducible gene-I (RIG-I) sufficiently restrains SARS-CoV-2 replication in human lung cells in a type I/III interferon (IFN)-independent manner.

Successful pregnancy involves the homeostasis between maternal decidua and fetoplacental units, whose disruption contributes to compromised pregnancy outcomes, including recurrent spontaneous abortion (RSA).

To compare outcomes before and after implementation of medical abortion (termination of pregnancy) without ultrasound via telemedicine, a large number of women with high-risk pregnancies are referred to hospital for abortion.

Although abortion became legal four decades ago, Americans remain staunchly divided over its acceptability. While researchers have been interested in the factors shaping abortion attitudes, there are almost no reviews of this work. We examine the factors shaping Americans’ abortion attitudes and assess the state of published peer‐reviewed articles in this area over the last 15 years. Using a mixed‐methods systematic review, we analyze and critique the findings from 116 journal articles that have examined attitudes about abortion between 2001 and 2016. Among the many predictors and outcomes exa...

Self-managed medication abortion provided using online telemedicine can be highly effective with low rates of serious adverse events and may offer a safe and effective option for those who cannot access clinical care.

Overall, denying all wanted induced abortions in the United States would increase pregnancy-related mortality substantially, even if the rate of unsafe abortion did not increase.

Findings from this prospective cohort study show that self-managed medication abortion with accompaniment group support is highly effective and, for those with pregnancies of less than 9 weeks' gestation, non-inferior to the effectiveness of clinician- managed medication abortion administered in a clinical setting.

Findings indicate that miR-146a-5p and mi-146b-5P derived from EVs play important roles in intercellular communication between M1 macrophages and trophoblasts, illuminating a novel mechanism in M1 Macrophage regulation of trophoblast biological behaviors and their role in RSA.
