Objective: The authors aimed to determine if medical students' self-assessment of abilities and performance differed by gender during the psychiatry clerkship and if these differences were reflected objectively in test scores or clinical evaluations from educators.

Methods: Data from mid-clerkship self-assessments completed during the psychiatry core clerkship were reviewed from two classes of medical students. Students rated their performance on 14 items across five domains: knowledge/clinical reasoning, differential diagnosis, data presentation, studying skills, and teamwork as "below," "at," or "above expected level.

Article Synopsis
  • Puberty presents unique challenges for individuals with autism spectrum disorder (ASD), including increased vulnerability, safety concerns, and worsened mood and behavioral issues.
  • Youth with ASD require targeted education on self-care, hygiene, sexual activity, and menstruation management, but healthcare providers often lack the preparation and confidence to meet these needs.
  • A pilot project demonstrated that a brief educational intervention significantly improved family nurse practitioners’ self-reported knowledge and attitudes toward caring for individuals with ASD, highlighting the importance of incorporating such training in nursing education.

Study Question: What is the association between infertility with or without fertility treatment and incident onset of systemic autoimmune rheumatic disease (SARD) among women who give birth?

Summary Answer: Women who experienced infertility but did not use fertility treatment had a higher incidence of SARD up to 9 years after delivery than those who did not experience infertility, even after accounting for their higher rates of preeclampsia, spontaneous preterm birth, and stillbirth.

What Is Known Already: Infertility is increasingly common and is an under-appreciated risk marker for chronic diseases in women. Despite several studies documenting abnormal immune activity in women with infertility, little is known about the association between infertility and incidence of autoimmune diseases such as SARD which disproportionately develops in reproductive-aged women.

CetZ proteins are archaea-specific homologs of the cytoskeletal proteins FtsZ and tubulin. In the pleomorphic archaeon , CetZ1 contributes to the development of rod shape and motility, and has been implicated in the proper assembly and positioning of the archaellum and chemotaxis motility proteins. CetZ1 shows complex subcellular localization, including irregular midcell structures and filaments along the long axis of developing rods and patches at the cell poles of the motile rod cell type.

The rich information of electron energy-loss spectroscopy (EELS) comes from the complex inelastic scattering process whereby fast electrons transfer energy and momentum to atoms, exciting bound electrons from their ground states to higher unoccupied states. To quantify EELS, the common practice is to compare the cross-sections integrated within an energy window or fit the observed spectrum with theoretical differential cross-sections calculated from a generalized oscillator strength (GOS) database with experimental parameters. The previous Hartree-Fock-based and DFT-based GOS are calculated from Schrödinger's solution of atomic orbitals, which does not include the full relativistic effects.
