Assessing and Improving the Effectiveness of Online Patient Education Materials on Essential Vocal Tremor: A Comprehensive Evaluation.

INTRODUCTION: Health literacy, a strong indicator of health outcomes, is an important aspect of good patient care. With an increasing reliance on the Internet for health information, online patient materials should be easily understood by the average reader. The American Medical Association (AMA) and National Institutes of Health (NIH) recommend that patient education materials be written at a sixth-grade level. Creating effective digital information requires careful consideration of not only word choice, but also many other factors including actionability, comprehensiveness, evidence, and visual organization. To support the creation of valuable online health content, the Office of Disease Prevention and Health Promotion (ODPHP) published Health Literacy Online, a research-based guide that discusses why and how to design digital health information tools.This study aims to assess the effectiveness of online patient education materials regarding vocal tremor, assess the effectiveness of patient education materials published by the American Laryngological Association, and to evaluate the usefulness of the Health Literacy Online guide in creating effective online patient education materials on laryngological diseases. METHODS: The first 50 unsponsored search results for the terms "vocal tremor" and "essential vocal tremor" were evaluated. Each website was analyzed using the Flesch Reading Ease Score (FRES) and Flesch-Kincaid Grade Level (FKGL) readability tests, the DISCERN instrument, and the Patient Education Materials Assessment Tool (PEMAT). The resources published by the American Laryngological Association were also evaluated in this manner. RESULTS: Of the 100 websites identified from the initial queries, 14 websites were included in this analysis. The average FRES and FKGL scores were 47.21 ± 10.47 and 10.96 ± 2.46, respectively, indicating that readers need a 11th-grade education to comprehend the materials. The average DISCERN score was 22.50 ± 9.76, indicating "very poor" quality with serious shortcomings and not appropriate sources of information about treatment choices. The average PEMAT understandability score was 68.43% ± 9.80% with an actionability score of 20.00% ± 23.53%, indicating the information was fairly difficult to process and do not help identify next steps. For the materials published by the American Laryngological Association (ALA), the average FRES and FKGL scores were 38.33 ± 12.81 and 12.56 ± 2.15, respectively, indicating a 12th-grade reading level. A DISCERN score of 27 was consistent across each item, indicating "very poor" quality. A PEMAT understandability score was 45% with an actionability score of 0%, indicating they are difficult to process and do not help identify next steps. After writing a revised sample of the information provided by the ALA based on the ODPHP's Health Literacy Online tool, the new FRES and FKGL score was 75.6 and 5.9, respectively. The new DISCERN score was 35. The new PEMAT understandability scores was 79% with actionability scores of 80%. CONCLUSION: This study found that most publicly available online patient education materials on essential vocal tremor and other laryngological diseases do not use plain language and require reading levels too advanced for the average reader to comprehend. In addition, most websites were of very poor quality readability, and were therefore less likely to benefit individuals in their decision-making. In an age where most people seek information on the Internet, the lack of easily understood online patient resources reduces the usefulness of these resources for many individuals. Professional organizations and societies like the American Laryngological Association may consider the use of the Health Literacy Online tool as a resource to provide both accurate and easily understandable patient education resources.

Medical Student Research Activity in Otolaryngology.

OBJECTIVE: To investigate medical student research productivity by institutions associated with otolaryngology residency programs and identify correlates of productivity. STUDY DESIGN: Retrospective review. SETTING: N/A. METHODS: A systematic search for articles indexed on PubMed published by 116 programs from January 1, 2016 to February 28, 2021 was conducted. Primary outcomes were number of faculty publications, first-author medical student publications and medical students from each institution. Secondary outcomes included geographic region, number of otolaryngology faculty members, and program rankings. RESULTS: Nationally, the mean number of faculty per institution was 21.7 at the time of search. Over a 5-year period, there was a mean 98.7 total publications and 15.8 medical student first-author publications per institution consisting of a mean of 10.03 distinct medical students. One-way analysis of variance showed no statistically significant difference in medical student productivity (P = .09) or department size (P = .12) between regions. Number of medical student first-author publications positively correlated to number of faculty (R = .43, P < .05) and number of faculty publications (R = .63, P < .05). The top 30 programs ranked by United States News & World Report or National Institute of Health for funding had a statistically significantly greater mean number of medical student first-author publications and distinct medical student first authors than all other programs (P < .05). CONCLUSION: Greater numbers of faculty members likely provide more mentorship and opportunities that allow medical students to engage in projects that lead to first-author publications. These findings allow institutions to reflect on efforts in medical student engagement and provide data to students for career planning.

To Use or Not to Use? Quantifying the Benefit of Microcatheter Use in Adrenal Vein Sampling.

Adrenal vein sampling is a technically difficult procedure with reported sampling success rates as low as 41%. Routine microcatheter use has been suggested by some to improve sampling adequacy. This study is a single-institution retrospective review of adrenal vein sampling procedures performed from 2014 to 2021 to quantify sample selectivity and adequacy with and without the use of a microcatheter. Microcatheter sampling was performed in 43 (47%) of 92 cases on the right adrenal gland and 44 (48%) of 92 cases on the left adrenal gland. Mean selectivity index was significantly higher bilaterally with microcatheters (right, 36.8 vs 27.7; P = .05; left, 33.9 vs 19.9 left; P < .001). However, sampling adequacy rates did not significantly differ between microcatheter and 5-F sampling bilaterally (right, 91% vs 90%; P = .88; left, 96% vs 98%; P = .51). Adrenal hemorrhage occurred exclusively with right-sided microcatheter sampling (n = 6, 13%). In conclusion, although microcatheter sampling increases mean selectivity index, it does not change sampling adequacy rate and may increase the risk of right adrenal hemorrhage.

HLA homozygosity is associated with Non-Hodgkin lymphoma.

The "heterozygote advantage" hypothesis has been postulated regarding the role of human leukocyte antigen (HLA) in non-Hodgkin lymphoma (NHL), where homozygous loci are associated with an increased risk of disease. In this retrospective study, we analyzed the HLA homozygosity of 3789 patients with aplastic anemia (AA), acute lymphocytic leukemia (ALL), acute myeloblastic leukemia (AML), chronic lymphocytic leukemia (CLL), chronic myeloid leukemia (CML), myelodysplastic syndrome (MDS), multiple myeloma (MM), and non-Hodgkin lymphoma (NHL) at HLA-A, B, C, DRB1 and DQB1 loci compared to 169,964 normal controls. HLA homozygosity at one or more loci was only associated with an increased risk in NHL patients (OR = 1.28, 95% CI [1.09, 1.50], p = 0.002). This association was not seen in any of the other hematologic diseases. Homozygosity at HLA-A alone, HLA-B + C only, and HLA-DRB1 + DQB1 only was also significantly associated with NHL. Finally, we observed a 17% increased risk of NHL with each additional homozygous locus (OR per locus = 1.17, 95% CI [1.08, 1.25], p trend = 2.4 × 10-5). These results suggest that reduction of HLA diversity could predispose individuals to an increased risk of developing NHL.

Blood type change identifies late dominance reversal of chimerism after double umbilical cord blood transplantation with review of the literature.

BACKGROUND: A 30-year-old man underwent double umbilical cord blood transplantation (UCBT) for acute myeloid leukemia (AML) with reduced intensity conditioning. The cords had identical HLA types and were each a 5/6 match to the patient. Following transplantation, cord 2 initially dominated all tested cell populations. At day +306, we observed an unusual reversal of dominance chimerism pattern in which cord 1 instead dominated all tested populations. STUDY DESIGN & METHODS: Polymerase chain reaction (PCR)-based short tandem repeat (STR) assays were performed on the peripheral blood and bone marrow samples. The white blood cell (WBC) populations from the peripheral blood were manipulated for testing to create subpopulations enriched for CD3, CD33, and CD56. RESULTS: Chimerism studies on day +77 showed the following: cord 1: 44%-CD3; 0%-CD33; 16%-CD56; cord 2: 56%-CD3; 100%-CD33; 84%-CD56. Cord 2 initially dominated in all tested cell populations. Chimerism studies performed on post-transplantation day +306 uncovered a reversal of dominance chimerism pattern in which cord 1 now dominated in all cell populations (cord 1: 82%-CD3; >95%-CD33; 67%-CD56; cord 2: 18%-CD3; <5%-CD33; 33%-CD56). Between days +127 and +244, the patient's blood type shifted from B Rh-positive to A Rh-negative. CONCLUSION: The change in the patient's blood type identified a late reversal of dominance chimerism pattern. This is a rare occurrence, previously cited only once, which is inconsistent with published data that early high CD3 counts and unseparated bone marrow chimerism predominance at day +100 predict long-term cord dominance in double UCBT in the vast majority of cases.

Case report of familial COVID-19 cluster associated with High prevalence of anosmia, ageusia, and gastrointestinal symptoms.

BACKGROUND: Patients with COVID-19 most commonly report respiratory symptoms, with a minority reporting gastrointestinal (GI) symptoms in currently available reports. Additionally, little is known about the symptoms of anosmia/hyposmia, ageusia, and dysgeusia anecdotally seen in COVID-19 patients, which may potentially be considered both GI and sensory/neurological manifestations of infection. We hope to clarify the prevalence of these symptoms and patterns of transmission within a family cluster. CASE PRESENTATION: We interviewed 7 patients via oral inquiries and a questionnaire, collecting data on subject symptoms and their durations. Reverse transcriptase-polymerase chain reaction (RT-PCR) was used to confirm 2 of these cases. We report a familial cluster of 5 presumed and 2 confirmed COVID-19 cases, all of whom reported one or more GI symptoms and 5 of whom reported sensory symptoms of anosmia/hyposmia, ageusia/hypogeusia, and/or dysgeusia. CONCLUSIONS: This frequency of GI symptoms is high relative to currently available epidemiological reports, which also infrequently report on sensory symptoms. COVID-19 exhibits wide variation in duration, severity, and progression of symptoms, even within a familial cluster.
