Preliminary results of repetitive transorbital alternating current stimulation in optic neuropathies [Meeting Abstract]

Livengood, H; Wollstein, G; Ishikawa, H; Wu, M; Liu, M; Achanta, P; Al-Aswad, L A; Panarelli, J F; Misra, P; Do, A; Sabel, B A; Schuman, J S
Purpose : Repetitive transorbital alternating current stimulation (rtACS) is an application of weak electric current near the eyes used in vision rehabilitation of optic neuropathies (ON). Conceptually rtACS entrains neuronal oscillations, augmenting neuronal function. In subjects with ON we evaluated whether rtACS influenced visual structure and function. Methods : 34 subjects with ON enrolled in a prospective trial underwent comprehensive ophthalmic evaluation, visual field (VF) 24-2 and 10-2 tests (Humphrey Field Analyzer) and OCT (Cirrus HD-OCT) retinal nerve fiber layer (RNFL) and ganglion cell inner plexiform layer (GCIPL) thicknesses at baseline and follow-up (FU) visits. Subjects received rtACS 30-to 45-minutes daily for 10 days. Sham subjects (n=4) underwent the same procedures but received no current. Point-by-point analyses of VF total deviation (TD) values were conducted between rtACS and sham groups. Regression analyses determined rate of change for each TD point per eye (significant points with positive rate of change defined as improved, negative rate of change as progressed; insignificant rate of change as no change) and the association between RNFL and GCIPL between groups. Results : The number of FU visits with VF tests ranged 2 to 7, with no significant differences detected between rtACS vs sham groups' FU duration. No significant differences were detected between groups' baseline VF 24-2 and 10-2 mean deviation (MD) values (Table 1). The average numbers of improved points (VF 10-2) and progressed points (VF 24-2) were greater for rtACS while the average number of no change points was greater for sham (VF 24-2, p0.05, Table 1). Further analysis of FU duration determined a significant interaction with rtACS; number of improved points (VF 10-2) and progressed points (VF 24-2, p<0.02) were not sustained over time. No significant differences were detected in average RNFL and GCIPL thicknesses between groups. Conclusions : Preliminary analyses of the effect of rtACS in ON indicate initial improvement but not a clear benefit over time. Detection of differences between rtACS vs sham groups may be biased due to the small sham sample and range of FU duration as VF test-to-test variability is known to increase with worsening VF MD. Future analyses will assess interim effect at early vs late FU time points to evaluate the role of rtACS in vision rehabilitation

Designing a quality monitoring system for low-resource ophthalmology clinics using Bayesian analysis [Meeting Abstract]

Massa, S; Lu, Y; Misra, P; Anthopolos, R; Elkin, Z
Purpose : Ophthalmology clinics with minimal statistical analytics capabilities may struggle to implement a quality monitoring system to evaluate patient outcomes. We performed a quality improvement study by designing a quality monitoring system for a low-resource ophthalmology clinic that would use small samples to estimate outcomes for larger patient populations. Methods : We evaluated the proportion of primary open-angle glaucoma (POAG) patients who were treated successfully according to American Academy of Ophthalmology Preferred Practice Patterns (PPPs). We analyzed 100 patients seen in the clinic over 3 months in 2019 as the input for our Bayesian analysis. We also created a standardized note template for use by clinicians in the electronic medical record (EMR) for POAG patient visits to facilitate monitoring of treatment successes without requiring clinical expertise. We evaluated adherence to clinician template use in POAG patient notes on the weekly day of glaucoma patient visits over 9 weeks in 2020. Results : Using Bayesian analysis based on our initial data, we created tables that allow for quality monitoring of future 3 month intervals using parameters from smaller samples. Using a small sample of 30 patients, we were able to determine that there was a 100% probability that the clinic as a whole was not achieving the pre-defined target percentage of 80% of POAG patients successfully treated, as defined by the PPPs. Regarding adherence to use of the note template for POAG patients, the median proportion of patients for which the template was used on a single clinic day was 27%, with a maximum of 53% and a minimum of 11%. Conclusions : Based on the input parameters of the number of patients in the sample, the number of treatment successes in that sample, and the target proportion of successfully treated patients, a small sample Bayesian analysis can be used for quality monitoring of patient outcomes for larger patient populations in low-resource clinical settings. Future work includes creation of an open-access database of tables derived from Bayesian analysis for use as a reference by other low-resource clinics in quality monitoring efforts

Late-onset angle closure in pseudophakic eyes with posterior chamber intraocular lenses

Krawitz, Brian D; Misra, Poonam; Bearelly, Srilaxmi; Al-Aswad, Lama A
Two patients presented with angle closure many years after cataract extraction. The first patient presented with acute intraocular pressure (IOP) elevation and closed iridocorneal angle that resolved with a laser iridotomy. The second patient presented with an insidious course of high IOP and progressive narrowing of the iridocorneal angle, ultimately requiring a pars plana vitrectomy and glaucoma valve implant, with subsequent normalization of pressure and angle anatomy. While rare, angle closure in eyes with posterior chamber intraocular lenses is a dangerous complication that can occur many years after cataract extraction. Retained lens fragments, and perhaps repeated intravitreal injections, might place susceptible patients at risk.

Gender differences in promotion and scholarly impact: an analysis of 1460 academic ophthalmologists

Lopez, Santiago A; Svider, Peter F; Misra, Poonam; Bhagat, Neelakshi; Langer, Paul D; Eloy, Jean Anderson
OBJECTIVES/OBJECTIVE:In recent years, gender differences in academic promotion have been documented within surgical fields. To the best of our knowledge, gender discrepancies in association with scholarly productivity have not been well assessed among academic ophthalmologists. Because research productivity is strongly associated with academic career advancement, we sought to determine whether gender differences in scholarly impact, measured by the h-index, exist among academic ophthalmologists. DESIGN/METHODS:Academic rank and gender were determined using faculty listings from academic ophthalmology departments. h-index and publication experience (in years) of faculty members were determined using the Scopus database. SETTING/METHODS:Academic medical center. RESULTS:From assistant professor through professor, the h-index increased with subsequent academic rank (p < 0.001), although between chairpersons and professors no statistical difference was found (p > 0.05). Overall, men had higher h-indices (h = 10.4 ± 0.34 standard error of mean) than women (h = 6.0 ± 0.38 standard error of mean), a finding that was only statistically significant among assistant professors in a subgroup analysis. Women were generally underrepresented among senior positions. When controlling for publication range (i.e., length of time publishing), men had higher h-indices among those with 1 to 10 years of publication experience (p < 0.0001), whereas women had scholarly impact equivalent to and even exceeding that of men later in their careers. CONCLUSION/CONCLUSIONS:Women in academic ophthalmology continue to be underrepresented among senior faculty. Although women surpass men in scholarly productivity during the later stages of their careers, low scholarly impact during the earlier stages may impede academic advancement and partly explain the gender disparity in senior academic positions.

Management of sinonasal teratocarcinosarcoma: a systematic review

Misra, Poonam; Husain, Qasim; Svider, Peter F; Sanghvi, Saurin; Liu, James K; Eloy, Jean Anderson
PURPOSE/OBJECTIVE:Sinonasal teratocarcinosarcoma (SNTCS) is a rare and highly malignant neoplasm that often involves the anterior skull base. This study reviews the published literature related to SNTCS. Clinical presentation, demographics, radiographic diagnosis, pathology, treatment, and management outcomes of this uncommon disease are reported. METHODS:A systematic review in the published English literature was conducted. A MEDLINE/PubMed search and bibliographic examination of articles pertaining to SNTCS were performed. Each case was analyzed for patient demographics, clinical presentation, tumor location, diagnosis, treatment, and survival outcome. RESULTS:A total of 49 journal articles were included. Individual patient data were reported in 86 cases. The average age of the patients was 54.5 years (range, 0.1 to 85 years), with a strong male predilection (7:1). Average follow-up was found to be 38.9 months (range, 2 to 372 months). The most common treatment method was surgery with radiation therapy, utilized in 59.3% of patients. Out of 71 cases with reported outcome and follow-up, there were 21 cases of recurrence, 8 cases with metastasis, and 6 cases reporting both recurrence and metastasis. Forty-two out of 71 (59.2%) patients survived at the time of follow-up. CONCLUSIONS:This study describes the largest pool of SNTCS patients to date. SNTCS is a rare and aggressive malignant skull base tumor with a poor prognosis with frequent recurrence and metastasis. Although a variety of treatment paradigms have been reported in the literature, radical surgical resection followed by radiation therapy appears to be the most commonly used treatment option.

Sanghvi, Saurin; Misra, Poonam; Patel, Neal R; Kalyoussef, Evelyne; Baredes, Soly; Eloy, Jean Anderson
PURPOSE/OBJECTIVE:Sinonasal rhabdomyosarcoma (SNRMS) is a rare malignancy which often presents with nasal obstruction, rhinorrhea and epistaxis. It is the most common sarcoma in children. In this study, we analyze the incidence and long-term survival for SNRMS using a national population-based database. METHODS:The United States National Cancer Institute's Surveillance, Epidemiology, and End Results (SEER) registry was utilized to calculate incidence and survival trends for SNRMS between 1973 and 2009. In addition, data were grouped by age, gender, race, and histopathological subtype. RESULTS:A total of 181 cases of SNRMS were analyzed for incidence trends, showing a 1.23:1 female to male ratio. While the overall incidence of SNRMS increased by 1.02% annually over the last 20years, this pattern was not equal amongst gender and racial groups. The incidence in males has increased, while in females incidence has decreased. An increase in incidence was noted in white and "others," but decreased in blacks. Using a total of 314 cases for survival analysis, we found that the rate in the white population has been consistently highest with a 5-year survival of 49.45%, 10- and 20-year survival of 48.81%. Survival rates in cases of embryonal SNRMS were also consistently higher than in cases of alveolar SNRMS. CONCLUSION/CONCLUSIONS:Overall incidence of SNRMS is increasing. Histologic subtype and race are important considerations in the long-term prognosis of SNRMS. Future studies will further elucidate gender and race related trends.

Readability assessment of the American Rhinologic Society patient education materials

Kasabwala, Khushabu; Misra, Poonam; Hansberry, David R; Agarwal, Nitin; Baredes, Soly; Setzen, Michael; Eloy, Jean Anderson
BACKGROUND: The extensive amount of medical literature available on the Internet is frequently accessed by patients. To effectively contribute to healthcare decision-making, these online resources should be worded at a level that is readable by any patient seeking information. The American Medical Association and National Institutes of Health recommend the readability of patient information material should be between a 4th to 6th grade level. In this study, we evaluate the readability of online patient education information available from the American Rhinologic Society (ARS) website using 9 different assessment tools that analyze the materials for reading ease and grade level of the target audience. METHODS: Online patient education material from the ARS was downloaded in February 2012 and assessed for level of readability using the Flesch Reading Ease, Flesch-Kincaid Grade Level, Simple Measure of Gobbledygook (SMOG) Grading, Coleman-Liau Index, Gunning-Fog Index, FORCAST formula, Raygor Readability Estimate, the Fry Graph, and the New Dale-Chall Readability Formula. Each article was pasted as plain text into a Microsoft(R) Word(R) document and each subsection was analyzed using the software package Readability Studio Professional Edition Version 2012.1. RESULTS: All healthcare education materials assessed were written between a 9th grade and graduate reading level and were considered "difficult" to read by the assessment scales. CONCLUSION: Online patient education materials on the ARS website are written above the recommended 6th grade level and may require revision to make them easily understood by a broader audience.

Readability analysis of healthcare-oriented education resources from the american academy of facial plastic and reconstructive surgery

Misra, Poonam; Agarwal, Nitin; Kasabwala, Khushabu; Hansberry, David R; Setzen, Michael; Eloy, Jean Anderson
OBJECTIVES/HYPOTHESIS: Deficient health literacy remains a widespread public issue. As such, the National Institutes of Health (NIH) recommends that all patient resources should be written around a sixth-grade level. The authors evaluate healthcare-oriented resources specified for patient use on the American Academy of Facial Plastic and Reconstructive Surgery (AAFPRS) Web site in order to identify potential areas of improvement and highlight those sections that may serve as paradigms for future revisions. STUDY DESIGN: Descriptive and correlational design. METHODS: Seventeen healthcare-oriented resources specifically for patients were downloaded in February 2012 from the American Academy of Facial Plastic and Reconstructive Surgery Web site. Readability assessments of each article were performed using Readability Studio Professional Edition Version 2012.1. These tests included the Flesch Reading Ease, Flesch-Kincaid Grade Level, SMOG Grading, Coleman-Liau Index, Gunning-Fog Index, the New Fog Count, the New Dale-Chall Readability Formula, FORCAST formula, Raygor Readability Estimate, and the Fry Graph. RESULTS: Patient health education material found on the AAFPRS Web site has been found to be written at an average grade level of 12th grade using 10 different readability scales. CONCLUSIONS: Modifications of the patient education section of the AAFPRS Web site can increase the readability of the literature, and allow greater comprehension among a wider audience.

Readability analysis of internet-based patient information regarding skull base tumors

Misra, Poonam; Kasabwala, Khushabu; Agarwal, Nitin; Eloy, Jean Anderson; Liu, James K
Readability is an important consideration in assessing healthcare-related literature. In order for a source of information to be the most beneficial to patients, it should be written at a level appropriate for the audience. The National Institute of Health recommends that health literature be written at a maximum level of sixth grade. This is not uniformly found in current health literature, putting patients with lower reading levels at a disadvantage. In February 2012, healthcare-oriented education resources were retrieved from websites obtained using the Google search phrase skull base tumors. Of the first 25 consecutive, unique website hits, 18 websites were found to contain information for patients. Ten different assessment scales were utilized to assess the readability of the patient-specific web pages. Patient-oriented material found online for skull base tumors was written at a significantly higher level than the reading level of the average US patient. The average reading level of this material was found to be at a minimum of eleventh grade across all ten scales. Health related material related to skull base tumors available through the internet can be improved to reach a larger audience without sacrificing the necessary information. Revisions of this material can provide significant benefit for average patients and improve their health care.
