Acute anterior uveitis is generally recognized as the most common form of uveitis. An association with HLA-B27 is seen in approximately half of cases of acute anterior uveitis. The prevalence of HLA-B27 varies widely between ethnic populations, with an approximate 8-10% prevalence in non-Hispanic whites and lower prevalence in Mexican- (4%) and African- (2-4%) Americans. A group of systemic inflammatory diseases, the spondyloarthropathies, similarly demonstrates a strong association with HLA-B27. The strength of association varies, depending on the specific spondyloarthropathy, with the strongest association found in patients with ankylosing spondylitis. The majority of patients with HLA-B27 associated uveitis will have an underlying spondyloarthropathy. Suspicion for HLA-B27 associated uveitis should prompt a careful clinical history to assess for features of a spondyloarthropathy as the characteristics of any associated uveitis may vary.

Purpose Professional identity formation (PIF) can be defined as the integration of the knowledge, skills, values, and behaviors of a profession with one’s preexisting identity and values. Several different, and sometimes conflicting, conceptualizations and theories about PIF populate the literature; applying these different theories in PIF curricula and pedagogic strategies can profoundly impact the PIF of future physicians. The authors conducted a critical review of the recent literature on PIF interventions in medical education to explore the conceptualizations of and theoretical approaches to PIF that underlie them. Method The authors searched articles on PIF educational interventions published in 5 major medical education journals between 2010 and March 2021. The articles’ context and findings were extracted, analyzed, and summarized to identify conceptualizations and theoretical approaches to PIF. Results The authors identified 43 studies examining medical education interventions aimed at influencing PIF. The majority of the studies (n = 31) focused on undergraduate medical education. Reflective writing and the use of narrative reflections were the dominant modes of student activity in PIF interventions, supporting the dominant individualist approach to PIF. Less commonly PIF was understood as a socialization process or as an active process with both individually and socially focused influences. Conclusions Relying on reflective writing as the intervention of choice to impact PIF feeds the dominant individualist perspective on PIF. An unintended consequence of this individualist orientation is that cultural problems embedded in the profession can become burdens for individual physicians to personally bear. Future education and research into PIF should account for theoretical preferences and the impact of these preferences.

Extensive development of the structure-activity relationships of a screening lead determined three important pharmacophores for gonadotropin-releasing hormone (GnRH) receptor antagonist activity. Incorporation of the 3,4,5-trimethylphenyl group at the 3-position, 2-(2(S)-azetidinyl)ethoxy group at the 4-position, and N-4-pyrimidinylcarboxamide at the 6-position of the quinolone core resulted in the identification of 4-(2-(azetidin-2(S)-yl)ethoxy)-7-chloro-2-oxo-3-(3,4,5-trimethylphenyl)-1,2-dihydroquinoline-6-carboxylic acid pyrimidin-4-ylamide (1) as a potent antagonist of the GnRH receptor. A 10(4)-fold increase in in vitro binding affinity is observed for the GnRH receptor as compared to the initial screening lead. Compound 1 exhibits nanomolar binding activity and functional antagonism at the human receptor and is 7-fold less active at the rhesus receptor. Intravenous administration of compound 1 to rhesus monkeys results in a significant decrease of the serum levels of downstream hormones, luteinizing hormone (79% decrease in area under the curve) and testosterone (92% decrease in area under the curve), at a dose of 3 mg/kg. Quinolone 1 is a potent nonpeptidyl antagonist for the human GnRH receptor that is efficacious for the suppression of luteinizing hormone and testosterone in primates.
