PURPOSE/UNASSIGNED:This study was to assess corneal epithelial thickness (CET) in patients with Sjogren's disease (SjD). METHODS/UNASSIGNED:A retrospective chart review was conducted of SjD patients from September 2021 to January 2022. Patient demographics, unanesthetized Schirmer's test, serologic markers, and symptoms as measured by the Ocular Surface Disease Index (OSDI) were reviewed. Epithelial thickness from both eyes was measured using anterior segment OCT at the central 3mm and concentric 5mm, 7mm, and 9mm zones for the superior, temporal, inferior, and nasal corneal quadrants. Associations between corneal epithelial thickness with patient demographics, clinical characteristics, and symptoms were evaluated using regression models. RESULTS/UNASSIGNED:Fifteen SjD patients (100% female) were included with a mean age of 58.4 years. Patients with Sjogren's disease had a significantly thinner superior corneal epithelium compared to the inferior epithelium (mean 47.7mm vs 53.1mm, p = 0.001). The epithelial thickness mean standard deviation (MSD) was significantly inversely correlated with the unanesthetized Schirmer test (r=-0.39, p = 0.005), suggesting that an overall variability of CET correlates with decreased aqueous tear production. SS-A, SS-B, ANA, and RF positivity were not associated with any measures of CET. CONCLUSION/UNASSIGNED:This pilot study suggests that there is significant superior versus inferior thinning of corneal epithelium in Sjogren's patients. There was a significant correlation between variability of corneal epithelial thickness and decreased tear production in Sjogren's patients. Further larger studies are needed to understand the relationship of CET with objective and subjective measurements of ocular surface disease.

PURPOSE OF REVIEW/OBJECTIVE:Meibomian gland dysfunction (MGD) is one of the most common disorders encountered by ophthalmologists, and its management can prove challenging for both clinicians and patients. Intense pulsed light (IPL), which has been historically used in the field of dermatology, has emerged as a tool to help improve meibomian gland function. The goal of this review is to assess the clinical efficacy, utility, and safety of IPL for the treatment of MGD. RECENT FINDINGS/RESULTS:In recent randomized controlled trials, IPL has been shown to improve meibomian gland function, and subsequently tear film quality and dry eye symptoms. The mechanism of action still remains unclear. Recent literature suggests that IPL may also be used in conjunction with other therapies, such as meibomian gland expression, low-level light therapy, and thermal pulsation. Careful attention should be placed on each patient's Fitzpatrick skin type, as well as protecting the ocular structures to reduce the risk of adverse effects. Cost, accessibility, as well as a limited duration of efficacy may be drawbacks. SUMMARY/CONCLUSIONS:There is significant evidence supporting that IPL may be used as a potential well tolerated and effective treatment for MGD, though there are certain caveats regarding its long-term efficacy, accessibility, and cost.

Within the healthcare sector, especially in the field of nephrology, the matter of gender and racial inequalities continues to be a critical concern that requires immediate focus. Women, particularly those of underrepresented racial groups, face significant challenges due to a lack of representation in research studies, leading to a deficit in knowledge about how kidney diseases affect them differently. These challenges are exacerbated by systemic biases in the healthcare system, which manifest in both gender and racial dimensions, hindering access to and the quality of care for kidney diseases. Addressing these complex disparities requires a recalibration of risk stratification models to include both gender- and race-specific factors and a transformation of healthcare policies to facilitate a more inclusive and sensitive approach. Essential to this transformation is the empowerment of women of all races to actively participate in their healthcare decisions and the strengthening of support systems to help them navigate the complexities of the healthcare environment. Furthermore, education programs must be designed to be culturally competent and address the unique needs and concerns of women across different racial backgrounds. Promoting a collaborative patient-provider relationship is crucial in fostering an environment where equity, dignity, and respect are at the forefront. The path to equitable nephrology care lies in a concerted, collective action from researchers, healthcare providers, policymakers, and patients, ensuring that every individual receives the highest standard of care, irrespective of gender or race.

PURPOSE/OBJECTIVE:The purpose of this study was to provide relative citation ratio (RCR) benchmark data for cornea and external diseases specialists. DESIGN/METHODS:This is a cross-sectional bibliometric analysis. SUBJECTS/METHODS:Subjects included were fellowship-trained cornea and external diseases faculty at Accreditation Council for Graduate Medical Education-accredited institutions in the United States. METHODS:Academic specialists were indexed using the National Institutes of Health iCite Web site. Publication count, mean RCR score, and weighted RCR score were obtained between October 2022 and January 2023 by examining PubMed-listed publications from 1980 to 2022. Data were compared by sex, career duration, academic rank, and acquisition of a Doctor of Philosophy. MAIN OUTCOME MEASURES/METHODS:The main outcome measures were publication count, mean RCR value, and weighted RCR value. RESULTS:The cohort included 602 specialists from 112 Accreditation Council for Graduate Medical Education-accredited institutions. These clinician-scientists produced highly impactful research with a median publication count of 15 (interquartile ranges 4-41), median RCR of 1.4 (interquartile ranges 0.91-1.88), and median-weighted RCR of 20.28 (5.3-66.69). Both academic rank and career length were associated with greater publication count and RCR values. Male sex was also associated with greater publications counts and RCR scores compared with female faculty. Acquisition of a Doctor of Philosophy was associated with greater publication counts and weighted RCR scores but no difference in mean RCR scores. CONCLUSIONS:Academic cornea and external diseases specialists conduct high-impact research, with a median RCR of 1.4, exceeding the NIH standard value of 1. These data provide RCR benchmark data for the field to inform self, institutional, and departmental evaluations. These results also highlight a significant gender disparity in the field necessitating efforts to increase female representation and ensure equal opportunities.

INTRODUCTION/BACKGROUND:Cenegermin is approved for treatment of neurotrophic keratopathy (NK) and has been studied in patients with stage 2 or 3 NK. This study evaluated the efficacy and safety of cenegermin in adults with stage 1 NK. METHODS:This was a phase IV, multicenter, prospective, open-label, uncontrolled trial. Adults with stage 1 NK (Mackie criteria) and decreased corneal sensitivity (≤ 4 cm) received 1 drop of cenegermin 20 mcg/ml in the affected eye(s) 6 times/day for 8 weeks with a 24-week follow-up. RESULTS:Of 37 patients, corneal epithelial healing was observed in 84.8% (95% confidence interval [CI] 68.1-94.9%; P < 0.001) at week 8; 95.2% (95% CI 76.2-99.9%; P < 0.001) of those patients remained healed at the end of the 24-week follow-up (week 32). At week 8, 91.2% (95% CI 76.3-98.1%; P < 0.001) of patients experienced improved corneal sensitivity; this improvement was observed in 82.1% (95% CI 63.1-93.9%; P < 0.001) of patients at week 32. Mean best-corrected distance visual acuity change from baseline at week 8 was - 0.10 logMAR (standard deviation [SD], 0.15; 95% CI - 0.16 to - 0.05; P < 0.001) and at week 32 was - 0.05 logMAR (SD, 0.16; 95% CI - 0.11 to 0.01; P = 0.122). At weeks 8 and 32, 15.2% (95% CI 5.1-31.9%; P < 0.001) and 10.7% (95% CI 2.3-28.2%; P < 0.001) of patients, respectively, had a 15-letter gain from baseline. At least one adverse event (AE) was reported by 73.0% and 45.7% of patients during the treatment and follow-up periods, respectively. The most common treatment-related, treatment-emergent AEs were eye pain (37.8%), blurred vision (10.8%), and eyelid pain (8.1%); these were mostly mild or moderate and were only reported during the treatment period. CONCLUSIONS:These results support the potential use of cenegermin for treating patients with stage 1 NK, and future confirmatory studies would be beneficial to elaborate on these findings.

Native cardiac valves in the setting of chronic injury undergo remodeling that includes fibrous thickening and dystrophic calcification, as well as neovascularization, that result in abnormal valve function. In order to characterize the presence of neovascularization in valves, a retrospective review of 1246 sequentially reviewed native cardiac valves of all types was performed, with correlation with other histopathologic features, and clinical and echocardiographic findings. Neovascularization was present in 55.5% of cases, with the greatest prevalence amongst aortic valves. While microvasculature (representing capillaries, venules, and/or lymphatics) was at least present in all cases of valves with neovascularization, arterial vessels were never identified in valves without also the finding of concomitant microvasculature present. Patients with neovascularization had a greater mean age and body mass index compared to those without, and the proportions of cases with significant coronary artery disease, dyslipidemia, diabetes mellitus, rheumatic fever, and malignancy were greater in the setting of valves with neovascularization compared to cases without. The rate of neovascularization increased with degree of valve thickening and/or calcification, and stenosis; in contrast, neovascularization was observed at a greater rate with decreasing degrees of regurgitation. The prevalence rates of hemosiderin-laden macrophages, osseous metaplasia, chondromatous metaplasia, smooth muscle, and chronic inflammation were greater in valves with neovascularization compared to valves without. Neovascularization within native cardiac valves is a frequent histopathologic alteration associated with chronic valve disease, likely representing a constituent of structural remodeling that mediates and reflects chronic injury.

BACKGROUND:Medical universities often face the ongoing challenge of identifying and supporting at-risk students to enhance retention rates and academic success. This study explores a comprehensive analysis of perceived at-risk factors impeding academic and career aspirations and compares the perspectives of students and faculty in a medical school. METHODS:We focused on first and second-year medical (MBBS) students and teaching faculty in an international medical college offering a twinning program in India and Malaysia. Our investigation involved a comprehensive assessment of 25 at-risk factors through Likert-type questionnaires distributed to 250 MBBS students and 50 teaching faculty. RESULTS:Our findings revealed distinct disparities in perceptions between faculty and students regarding mean scores of classroom engagement (p = 0.017), procrastination (p = 0.001), unrealistic goals (p = 0.026), emotional/behavioral problems (p = 0.008), limited key social skills (p = 0.023), and a non-supportive home environment (p = 0.001). These differences underscore the need for increased communication and understanding between faculty and students to address these risk factors effectively. In contrast, no significant disparities were observed among faculty and students' perceptions concerning mean scores of various potential at-risk factors, including academic unpreparedness, cultural/language barriers, individual guidance/mentoring, limited communication skills, racism/sexism, self-confidence, self-respect, self-concept, motivation, underprepared for current academic challenges, self-discipline, negative social network, negative peer culture, transportation time, college financial cost, college evaluation culture bias, broken college relationships, teaching methodology, and learning disabilities. However, varying degrees of influence were perceived by faculty and students, suggesting the importance of individualized support. CONCLUSION/CONCLUSIONS:This study contributes to the academic community by shedding light on the multifaceted nature of at-risk factors influencing student success. It underscores the need for proactive measures and tailored interventions to enhance student retention in higher education and academic achievement, fostering a sustainable foundation for lifelong learning and growth.
