Enhancing Mentorship Networks through the Experiences of Women Professors of Ophthalmology.

Purpose The aim of this study is to identify and characterize women professors in ophthalmology to enhance professional development and equity of women in academic ophthalmology. Design Cross-sectional descriptive survey study. Participants Participants in the survey were women in ophthalmology departments who have obtained full professor rank at their respective institutions. Methods A cross-sectional study was conducted using data from an electronic survey of women ophthalmologists and researchers who had obtained full professorship rank in ophthalmology. The survey included questions about degree obtained, training path, fellowship, length and trajectory of academic career, family or medical leave participation, previous positions, and mentorship involvement. Statistical comparisons were made based on response. Main Outcome Measures Survey responses to questions pertaining to three domains: education and training, academic career, and mentorship. Results Women that obtained the professor title within ophthalmology largely held Doctor of Medicine/Doctor of Osteopathic Medicine degrees, were more likely to have completed fellowship training, and on average took 11 to 15 years to obtain the full professor title. The participants held a variety of other positions and titles throughout their academic careers. The vast majority of women reported having between 1 and 3 mentors during their careers with the majority also noting they currently participate in mentoring programs. Surveys were completed by 62 (30% response rate) women full professors of ophthalmology. Conclusion The experiences women have along the academic path to professorship are described in this survey and can help to inform junior faculty. Literature review highlights the importance of mentorship for work productivity, retention, and promotion within academic medicine which is an element seen in the vast majority of our participants' career paths. Guided by the identification of women professors within departments of ophthalmology and characterization of their experiences, a new initiative called Women Professors of Ophthalmology was formed under the Association of University Professors of Ophthalmology's organizational structure in 2021. This group that is tailored for women professors of ophthalmology to foster peer mentorship and guidance is poised to increase the retention and promotion of women in academic ophthalmology.

Echinocandin Treatment of Candida albicans Biofilms Enhances Neutrophil Extracellular Trap Formation.

The nosocomial pathogen Candida albicans forms biofilms on medical devices that persist in the face of antifungals and host defenses. Echinocandins, the most effective antibiofilm drugs, have recently been shown to augment the activity of neutrophils against biofilms through an unknown mechanism. Here, we show that treatment of C. albicans biofilms with subinhibitory concentrations of echinocandins promotes the formation of neutrophil extracellular traps (NETs), structures of DNA, histones, and antimicrobial proteins with antifungal activity.

Mechanisms involved in the triggering of neutrophil extracellular traps (NETs) by Candida glabrata during planktonic and biofilm growth.

Candida spp. adhere to medical devices, such as catheters, forming drug-tolerant biofilms that resist killing by the immune system. Little is known about how C. glabrata, an emerging pathogen, resists attack by phagocytes. Here we show that upon encounter with planktonic (non-biofilm) C. glabrata, human neutrophils initially phagocytose the yeast and subsequently release neutrophil extracellular traps (NETs), complexes of DNA, histones, and proteins capable of inhibiting fungal growth and dissemination. When exposed to C. glabrata biofilms, neutrophils also release NETs, but significantly fewer than in response to planktonic cells. Impaired killing of biofilm parallels the decrease in NET production. Compared to biofilm, neutrophils generate higher levels of reactive oxygen species (ROS) when presented with planktonic organisms, and pharmacologic inhibition of NADPH-oxidase partially impairs NET production. In contrast, inhibition of phagocytosis nearly completely blocks NET release to both biofilm and planktonic organisms. Imaging of the host response to C. glabrata in a rat vascular model of infection supports a role for NET release in vivo. Taken together, these findings show that C. glabrata triggers NET release. The diminished NET response to C. glabrata biofilms likely contributes to the resilience of these structured communities to host defenses.
