"Children Have the Fairest Things to Say": Young Children's Engagement with Anti-Bias Picture Books.

This qualitative case study investigated how an early childhood teacher and young children in a public White-predominant kindergarten classroom engaged in critical discussions of anti-bias issues including racism, White privilege, gender stereotypes, gender nonconformity, sexism, and homophobia. Through the use of interactive read-alouds using anti-bias picture books, the study's findings revealed that (a) the children could participate in thoughtful interactions during anti-bias read-aloud sessions and showed their complex understanding of race and gender issues; (b) the children needed substantial support to engage in activism against social injustices; (c) the children displayed a variety of responses to the discussion questions and activities related to gender-themed picture books as most children had difficulties resisting gender binary conceptions and stereotypes while some children, especially boys, were strongly empowered to embrace gender-nonconforming practices; and finally (d) some children internalized and enacted anti-immigrant, anti-Blackness, and racial/gender discriminatory actions to which the early childhood teacher often failed to either disrupt or intervene.

Optimization of a standardized letter of recommendation for faculty who wish to support candidates applying to surgical training programs.

Letters of recommendation (LORs) play an important role in applicant selection for graduate medical education programs. LORs may be of increasing importance in the evaluation of applicants given the recent change of the USMLE Step 1 to pass/fail scoring and the relative lack of other objective measures by which to differentiate and stratify applicants. Narrative letters of recommendation (NLORs), although widely used, have certain limitations, namely variability in interpretation, introduction of gender/race bias, and performance inflation. Standardized letters of recommendation (SLOR) have been proposed as a potential corrective to these limitations. We conducted a series of semi-structured interviews and focus groups to gather perspectives from letter writers and readers to inform methods for improving information elicited by SLORs from which we collected and analyzed data using the constant comparative method and a process of iterative coding. We applied our findings to the development of a novel SLOR for use in surgical residency program applications and were subsequently invited to help revise existing SLORs for a surgical post-graduate training program.

Conscientious Objection to Gender-Affirming Surgery: A Cross-Sectional Analysis of Plastic Surgery and Urology Residency Programs.

OBJECTIVE: Medical conscientious objection is a federally protected right of physicians to refuse participation in medically indicated services or research activities that are incompatible with their ethical, moral, or religious beliefs. Individual provider objections to gender-affirming surgery have been documented, however the prevalence of such objections is unknown. Our study aimed to characterize physician objections to gender-affirming surgery in plastic surgery and urology residencies and to assess related institutional policies. DESIGN, SETTING, PARTICIPANTS: A cross-sectional electronic survey was administered to program leadership of 239 accredited US plastic surgery and urology residencies from February to October 2023. Trainee exposure to gender-affirming surgery, programmatic experience with objections, and presence and content of institutional objection policies were collected. Bivariate analyses were performed to determine associations with objectors. RESULTS: One-hundred and twenty-four plastic surgery (n = 59) and urology (n = 65) residencies completed the survey, representing a 52% response rate. Most programs included didactic training (n = 107, 86%) and direct clinical exposure (n = 98, 79%) to gender-affirming surgery. Few (n = 24, 19%) endorsed existent objection policies. Sixteen programs (13%) experienced objections to gender-affirming surgery by trainees (n = 15), faculty (n = 6), and staff (n = 1). Neither geographic region, exposure to gender-affirming surgery, nor presence of objection policies significantly contributed to programmatic objections. Programs with formal objection policies reported increased confidence in addressing future objection events (p = 0.017). CONCLUSIONS: Objection to gender-affirming surgery is a rare, but plausible occurrence amongst plastic surgery and urology trainees. Residency programs should consider anticipatory policies to protect patients and, when feasible, provide reasonable accommodations for objecting trainees.

Designed protein logic to target cells with precise combinations of surface antigens.

Precise cell targeting is challenging because most mammalian cell types lack a single surface marker that distinguishes them from other cells. A solution would be to target cells using specific combinations of proteins present on their surfaces. In this study, we design colocalization-dependent protein switches (Co-LOCKR) that perform AND, OR, and NOT Boolean logic operations. These switches activate through a conformational change only when all conditions are met, generating rapid, transcription-independent responses at single-cell resolution within complex cell populations. We implement AND gates to redirect T cell specificity against tumor cells expressing two surface antigens while avoiding off-target recognition of single-antigen cells, and three-input switches that add NOT or OR logic to avoid or include cells expressing a third antigen. Thus, de novo designed proteins can perform computations on the surface of cells, integrating multiple distinct binding interactions into a single output.
