Attitudes, concerns, and perceptions of patients undergoing fertility treatments in an abortion restrictive state in the aftermath of the Roe v. Wade reversal.

PURPOSE: To investigate the abortion views and reproductive concerns of current in vitro fertilization patients after the US Supreme Court Dobbs v. Jackson decision, which overturned the Roe v. Wade decision guaranteeing abortion access. METHODS: This is a cross-sectional survey of English-speaking patients undergoing in vitro fertilization from January to November 2022 at a large academic institution in a state with restricted abortion care. Participants completed a 43-question electronic survey which measured feelings about abortion, future fertility treatments, and embryo disposition both quantitatively and qualitatively. RESULTS: Of 543 eligible patients, 267 (49%) consented to participate when called and were sent the survey. Of those, 180 (67%) completed it, resulting in a total completion rate of 33%. The majority believe abortion should be legal in the case of birth defects (90.8%) or rape or incest (90.3%). A significant proportion (91.4%) expressed concerns about abortion being illegal in the state that they receive infertility care. They reported some concern about making embryos (89.6%), controlling what happens to them (95.4%), and discarding them (94.4%). Patients wrote about their concerns with pursuing fertility treatments, fear of not having access to needed medical care, and the desire to remain close to states with less restrictive abortion laws. CONCLUSIONS: The evolving political landscape surrounding access to reproductive care has created significant concerns regarding legal regulation of these treatments and the disposition of embryos. By understanding patients' concerns, health care providers can more effectively advocate for the protection of fertility treatments and patients' autonomy in embryo disposition.

Metabolomics by UHPLC-HRMS reveals the impact of heat stress on pathogen-elicited immunity in maize.

INTRODUCTION: Studies investigating crop resistance to abiotic and biotic stress have largely focused on plant responses to singular forms of stress and individual biochemical pathways that only partially represent stress responses. Thus, combined abiotic and biotic stress treatments and the global assessment of their elicited metabolic expression remains largely unexplored. In this study, we employed targeted and untargeted metabolomics to investigate the molecular responses of maize (Zea mays) to abiotic, biotic, and combinatorial stress. OBJECTIVE: We compared the inducible metabolomes of heat-stressed (abiotic) and C. heterostrophus-infected (biotic) maize and examined the effects of heat stress on the ability of maize to defend itself against C. heterostrophus. METHODS: Ultra-high-performance liquid chromatography-high-resolution mass spectrometry was performed on plants grown under control conditions (28 °C), heat stress (38 °C), Cochliobolus heterostrophus infection, or combinatorial stress [heat (38 °C) + C. heterostrophus infection]. RESULTS: Multivariate analyses revealed differential metabolite expression between heat stress, C. heterostrophus infection, and their respective controls. In combinatorial experiments, treatment with heat stress prior to fungal inoculation negatively impacted maize disease resistance against C. heterostrophus, and distinct metabolome separation between combinatorial stressed plants and the non-heat-stressed infected controls was observed. Targeted analysis revealed inducible primary and secondary metabolite responses to abiotic/biotic stress, and combinatorial experiments indicated that deficiency in the hydroxycinnamic acid, p-coumaric acid, may contribute to the heat-induced susceptibility of maize to C. heterostrophus. CONCLUSION: These findings demonstrate that abiotic stress can predispose crops to more severe disease symptoms, underlining the increasing need to investigate defense chemistry in plants under combinatorial stress.
