Perspectives on the Impact of the COVID-19 Pandemic on Research: A Cross-Sectional Survey of Pediatric Otolaryngologists.

OBJECTIVE: To investigate the perspectives of pediatric otolaryngologists on the impact of the coronavirus disease 2019 (COVID-19) pandemic on their research. METHODS: Two surveys were sent to members of the American Society of Pediatric Otolaryngology (ASPO) in 2019 and 2021 to assess research perspectives before and during the COVID-19 pandemic. The surveys contained questions about research engagement, barriers, time allocation, and shifts in research focus. RESULTS: The COVID-19 pandemic reshaped research within pediatric otolaryngology, with a mixed impact on the amount of time allocated to research endeavors. Almost half of respondents reported a change in research focus to COVID-19-related studies. Protected time and funding were significant pre-pandemic barriers, whereas reduced staff, collaboration opportunities, and enrollment limitations emerged as key pandemic-related obstacles. A personal commitment to research was most strongly correlated with time spent on this endeavor. During the pandemic, women were less likely to report an increase in research activity when compared to men, possibly due to a disproportionate burden of caregiving on women during school closures and stay-at-home orders. CONCLUSION: Overall, the pandemic prompted both increases and decreases in research time allocation, depending on individual circumstances and priorities. Despite new challenges, pediatric otolaryngologists remain committed to research and have continued to remain productive.

Understanding the Long Haulers of COVID-19: Mixed Methods Analysis of YouTube Content.

BACKGROUND: The COVID-19 pandemic had a devastating global impact. In the United States, there were >98 million COVID-19 cases and >1 million resulting deaths. One consequence of COVID-19 infection has been post-COVID-19 condition (PCC). People with this syndrome, colloquially called long haulers, experience symptoms that impact their quality of life. The root cause of PCC and effective treatments remains unknown. Many long haulers have turned to social media for support and guidance. OBJECTIVE: In this study, we sought to gain a better understanding of the long hauler experience by investigating what has been discussed and how information about long haulers is perceived on social media. We specifically investigated the following: (1) the range of symptoms that are discussed, (2) the ways in which information about long haulers is perceived, (3) informational and emotional support that is available to long haulers, and (4) discourse between viewers and creators. We selected YouTube as our data source due to its popularity and wide range of audience. METHODS: We systematically gathered data from 3 different types of content creators: medical sources, news sources, and long haulers. To computationally understand the video content and viewers' reactions, we used Biterm, a topic modeling algorithm created specifically for short texts, to analyze snippets of video transcripts and all top-level comments from the comment section. To triangulate our findings about viewers' reactions, we used the Valence Aware Dictionary and Sentiment Reasoner to conduct sentiment analysis on comments from each type of content creator. We grouped the comments into positive and negative categories and generated topics for these groups using Biterm. We then manually grouped resulting topics into broader themes for the purpose of analysis. RESULTS: We organized the resulting topics into 28 themes across all sources. Examples of medical source transcript themes were Explanations in layman's terms and Biological explanations. Examples of news source transcript themes were Negative experiences and handling the long haul. The 2 long hauler transcript themes were Taking treatments into own hands and Changes to daily life. News sources received a greater share of negative comments. A few themes of these negative comments included Misinformation and disinformation and Issues with the health care system. Similarly, negative long hauler comments were organized into several themes, including Disillusionment with the health care system and Requiring more visibility. In contrast, positive medical source comments captured themes such as Appreciation of helpful content and Exchange of helpful information. In addition to this theme, one positive theme found in long hauler comments was Community building. CONCLUSIONS: The results of this study could help public health agencies, policy makers, organizations, and health researchers understand symptomatology and experiences related to PCC. They could also help these agencies develop their communication strategy concerning PCC.

Comparing Satisfaction Among Providers Treating Both Pediatric and Adult Otolaryngology Patients.

Objective: Although pediatric otolaryngology providers are reported to garner lower patient satisfaction than adults, this difference is not well characterized. This study investigates whether patient satisfaction differences exist in providers who treat both pediatric and adult patients. Study Design: Retrospective review. Setting: Tertiary medical center. Methods: In this cross-sectional study, Press Ganey surveys (PGS) completed by patients or parents on their first-time visit with 5 general otolaryngology providers from July 2014 to March 2022 were analyzed. Surveys were categorized by child (<18 years old) or adult and consisted of 14 items including 6 service domains of access, visit, nursing, provider, personal issues, and assessment. Analysis was performed with Walsh's t test and analysis of variance. Multivariable logistic regression, controlling for wait times and provider, evaluated the likelihood of highest satisfaction scores (HI-SCORES) based on age. Results: A total of 2549 patients (135 pediatric, 2414 adults) completed the PGS on their initial visit. There was no significant difference in the mean overall satisfaction scores between pediatric and adult patients. Further analysis of service domains among pediatric patients found the mean score in the access domain to be higher for the 6- to 11-year-old age group (0-5 years old: 85.5 ± 20.5 [mean ± SD], 6-11 years old: 94.7 ± 11.5, 12-17 years old: 87.3 ± 15.4, P = .03). Pediatric patients did not have a significantly higher likelihood (odds ratio = 1.1, 95% confidence interval: 0.8-1.6, P > .05) of reporting HI-SCORES compared to adults after covariate adjustment. Conclusion: There was no significant difference in patient satisfaction scores for providers who treat pediatric and adult patients utilizing the same facility and scheduling team.

Using unstructured crowd-sourced data to evaluate urban tolerance of terrestrial native animal species within a California Mega-City.

In response to biodiversity loss and biotic community homogenization in urbanized landscapes, there are increasing efforts to conserve and increase biodiversity within urban areas. Accordingly, around the world, previously extirpated species are (re)colonizing and otherwise infiltrating urban landscapes, while other species are disappearing from these landscapes. Tracking the occurrence of traditionally urban intolerant species and loss of traditionally urban tolerant species should be a management goal of urban areas, but we generally lack tools to study this phenomenon. To address this gap, we first used species' occurrences from iNaturalist, a large collaborative dataset of species observations, to calculate an urban association index (UAI) for 967 native animal species that occur in the city of Los Angeles. On average, the occurrence of native species was negatively associated with our composite measure of urban intensity, with the exception of snails and slugs, which instead occur more frequently in areas of increased urban intensity. Next, we assessed 8,348 0.25 x 0.25 mile grids across the City of Los Angeles to determine the average grid-level UAI scores (i.e., a summary of the UAIs present in a grid cell, which we term Community Urban Tolerance Index or CUTI). We found that areas of higher urban intensity host more urban tolerant species, but also that taxonomic groups differ in their aggregate tolerance of urban areas, and that spatial patterns of tolerance vary between groups. The framework established here has been designed to be iteratively reevaluated by city managers of Los Angeles in order to track the progress of initiatives to preserve and encourage urban biodiversity, but can be rescaled to sample different regions within the city or different cities altogether to provide a valuable tool for city managers globally.

SIRT4 loss reprograms intestinal nucleotide metabolism to support proliferation following perturbation of homeostasis.

The intestine is a highly metabolic tissue, but the metabolic programs that influence intestinal crypt proliferation, differentiation, and regeneration are still emerging. Here, we investigate how mitochondrial sirtuin 4 (SIRT4) affects intestinal homeostasis. Intestinal SIRT4 loss promotes cell proliferation in the intestine following ionizing radiation (IR). SIRT4 functions as a tumor suppressor in a mouse model of intestinal cancer, and SIRT4 loss drives dysregulated glutamine and nucleotide metabolism in intestinal adenomas. Intestinal organoids lacking SIRT4 display increased proliferation after IR stress, along with increased glutamine uptake and a shift toward de novo nucleotide biosynthesis over salvage pathways. Inhibition of de novo nucleotide biosynthesis diminishes the growth advantage of SIRT4-deficient organoids after IR stress. This work establishes SIRT4 as a modulator of intestinal metabolism and homeostasis in the setting of DNA-damaging stress.

Congenital Cytomegalovirus Testing Outcomes From the ValEAR Trial.

OBJECTIVE: To determine the positivity rate of congenital cytomegalovirus (cCMV) testing among universal, hearing-targeted CMV testing (HT-cCMV) and delayed targeted dried blood spot (DBS) testing newborn screening programs, and to examine the characteristics of successful HT-cCMV testing programs. STUDY DESIGN: Prospective survey of birth hospitals performing early CMV testing. SETTING: Multiple institutions. METHODS: Birth hospitals participating in the National Institutes of Health ValEAR clinical trial were surveyed to determine the rates of cCMV positivity associated with 3 different testing approaches: universal testing, HT-cCMV, and DBS testing. A mixed methods model was created to determine associations between successful HT-cCMV screening and specific screening protocols. RESULTS: Eighty-two birth hospitals were surveyed from February 2019 to December 2021. Seven thousand six hundred seventy infants underwent universal screening, 9017 infants HT-cCMV and 535 infants delayed DBS testing. The rates of cCMV positivity were 0.5%, 1.5%, and 7.3%, respectively. The positivity rate for universal CMV screening was less during the COVID-19 pandemic than that reported prior to the pandemic. There were no statistically significant drops in positivity for any approach during the pandemic. For HT-cCMV testing, unique order sets and rigorous posttesting protocols were associated with successful screening programs. CONCLUSION: Rates of cCMV positivity differed among the 3 approaches. The rates are comparable to cohort studies reported in the literature. Universal CMV prevalence decreased during the pandemic but not significantly. Institutions with specific order set for CMV testing where the primary care physician orders the test and the nurse facilitates the testing process exhibited higher rates of HT-cCMV testing.

Hearing Following Prolonged and Delayed Ganciclovir Treatment in a Murine Cytomegalovirus Model.

OBJECTIVE: Compare hearing outcomes utilizing standard, prolonged and delayed ganciclovir (GCV) therapy in a murine model of cytomegalovirus (CMV). METHODS: BALB/c mice were inoculated with mouse cytomegalovirus (mCMV) or saline via intracerebral injection on postnatal day 3 (p3). Intraperitoneal GCV or saline was administered at 12 h intervals for the duration of the standard (p3-p17), delayed (p30-p44), or prolonged treatment windows (p3-p31). Auditory thresholds were assessed using distortion product otoacoustic emission (DPOAE) and auditory brainstem response (ABR) testing at 4, 6, and 8 weeks of age. Blood and tissue samples were harvested from mice on p17 and p37 one hour after GCV administration, and their concentrations were assessed via liquid chromatography-mass spectrometry. RESULTS: A delayed course of GCV improved ABR but not DPOAE thresholds in mCMV-infected mice. A prolonged course of GCV did not provide better hearing thresholds than those administered standard treatment. The average GCV concentration in all 17-day-old mice tissue was significantly higher than those in older 37-day-old mice. CONCLUSION: Delayed GCV treatment provided a hearing benefit on ABR over untreated mCMV infected mice. Prolonged CGV administration showed no benefit compared to a shorter duration GCV treatment. GCV drug concentrations both systemically and in the cochlea are much lower in older mice. These results have potential implications for the clinical management of cCMV infected children.

Can Ganciclovir and Quercetin-P188 Ameliorate Cytomegalovirus Induced Hearing Loss?

OBJECTIVE: Determine whether combination therapy with ganciclovir (GCV) and a Quercetin-P188 solution improves hearing outcomes in a murine cytomegalovirus (CMV) model. METHODS: BALB/c mice were infected with murine CMV on postnatal day 3 (p3). Quercetin was solubilized in saline using P188 (QP188). Treatment groups received either GCV, QP188, GCV and QP188, or P188 delivery vehicle BID at 12-hour intervals via intraperitoneal injection. All treatment groups were treated for 14 days starting at p3. Uninfected controls were treated with the combined regimen, saline or P188 delivery vehicle. Auditory thresholds were assessed using distortion product otoacoustic emission (DPOAE) and auditory brainstem response (ABR) testing at 4, 6, and 8 weeks of age. Temporal bones from separate CMV-infected groups were harvested at p10, and viral load was determined by quantitative polymerase chain reaction. RESULTS: CMV-infected mice receiving combination therapy GCV+QP188 demonstrated statistically significant lower ABR (p < 0.001) and DPOAE thresholds (p < 0.001) compared with mice treated with GCV monotherapy, QP188 monotherapy, and P188 delivery vehicle at 4, 6, and 8 weeks of age. GCV+QP188 combination therapy, GCV monotherapy, and QP188 monotherapy resulted in a nonsignificant reduction in mean viral titers compared to P188 monotherapy (p = 0.08). CONCLUSION: Combining GCV with the excipients quercetin and P188 effectively ameliorated CMV-induced sensorineural hearing loss in a murine model. This result may be partially explained by a reduction in viral titers in mouse temporal bones that correlate with in vitro studies demonstrating additive antiviral effect in cell culture. LEVEL OF EVIDENCE: NA Laryngoscope, 134:1457-1463, 2024.

Tympanomastoidectomy versus parenteral antibiotic therapy for pediatric otorrhea.

OBJECTIVE: To evaluate the efficacy of tympanomastoidectomy versus parenteral antibiotic therapy for otorrhea as a result of chronic suppurative otitis media (CSOM) without cholesteatoma in the pediatric population. METHODS: A retrospective review of 221 patients treated for otorrhea at a tertiary academic pediatric hospital was performed to evaluate the impact of tympanomastoidectomy versus parenteral antibiotic therapy on resolution of otorrhea. Inclusion criteria were age 0-18 years, prior treatment with otic and/or oral antibiotic, prior history of tympanostomy tube placement for recurrent otitis media, history of otorrhea, treatment with tympanomastoidectomy or parenteral antibiotic therapy, and follow-up of at least 1 month after intervention. Time to resolution was compared between the two modalities adjusting for age, bilateral ear disease status, and comorbidities using a Cox proportional hazard model. RESULTS: Eighty-three ears from 58 children met the inclusion criteria. Ears that initially underwent tympanomastoidectomy had a significantly shorter time to resolution of symptoms (median time to resolution) 9 months (95 % confidence interval CI: 6.2-14.8) vs. 48.5 months (95 % lower CI 9.4, p = 0.006). On multivariate analysis, however, only bilateral ear disease status was independently associated with time to resolution of symptoms (hazard ratio 0.4, 95 % CI 0.2-0.9, p = 0.03). There was no statistically significant difference in the rate of treatment-related complications when comparing tympanomastoidectomy to parenteral antibiotic therapy (p = 0.37). CONCLUSION: When adjusting for age, bilateral ear disease status, and comorbidities, there does not appear to be a significant difference in time to resolution of symptoms when comparing parenteral antibiotic therapy to tympanomastoidectomy. An informed discussion regarding risks and benefits of each approach should be employed when deciding on the next step in management for patients with CSOM who have failed more conservative therapies.

My Precious Friend: Human-Robot Interactions in Home Care for Socially Isolated Older Adults.

OBJECTIVES: Using a friendship framework, we explored interactions between a multi-functional companion robot and older adults residing in a low-resource community in South Korea. METHODS: We conducted in-depth interviews with 12 older adults who kept a doll-shaped companion robot called Hyodol for 18 months on average. We applied the Framework Analysis Method to explore three types of friendship (i.e., friendships of utility, pleasure, and the good) that participants cultivated with the robot. RESULTS: The most common aspect of utility companionship reported by all participants was Hyodol's role as their health coach who reminded them to take medication and to exercise. Participants also found pleasure in playing with Hyodol and reported reduced feelings of loneliness. In the absence of other social supports, all participants also regarded Hyodol as a surrogate family member or human-friend, and interacted with Hyodol as such. CONCLUSIONS: Findings illustrated high acceptability of Hyodol among these socially isolated older adults especially during the global COVID-19 pandemic, suggesting that a humanoid like Hyodol could be complementary to homecare services for solo-living older adults. CLINICAL IMPLICATIONS: Well-designed robot interventions, as complements to existing aging service and clinical interventions, have a potential to improve health behaviors among socially isolated older adults.

Reducing single-use cutlery with green nudges: Evidence from China's food-delivery industry.

Rising consumer demand for online food delivery has increased the consumption of disposable cutlery, leading to plastic pollution worldwide. In this work, we investigate the impact of green nudges on single-use cutlery consumption in China. In collaboration with Alibaba's food-delivery platform, Eleme (which is similar to Uber Eats and DoorDash), we analyzed detailed customer-level data and found that the green nudges-changing the default to "no cutlery" and rewarding consumers with "green points"-increased the share of no-cutlery orders by 648%. The environmental benefits are sizable: If green nudges were applied to all of China, more than 21.75 billion sets of single-use cutlery could be saved annually, equivalent to preventing the generation of 3.26 million metric tons of plastic waste and saving 5.44 million trees.

Health Information on Pre-Exposure Prophylaxis From Search Engines and Twitter: Readability Analysis.

BACKGROUND: Pre-exposure prophylaxis (PrEP) is proven to prevent HIV infection. However, PrEP uptake to date has been limited and inequitable. Analyzing the readability of existing PrEP-related information is important to understand the potential impact of available PrEP information on PrEP uptake and identify opportunities to improve PrEP-related education and communication. OBJECTIVE: We examined the readability of web-based PrEP information identified using search engines and on Twitter. We investigated the readability of web-based PrEP documents, stratified by how the PrEP document was obtained on the web, information source, document format and communication method, PrEP modality, and intended audience. METHODS: Web-based PrEP information in English was systematically identified using search engines and the Twitter API. We manually verified and categorized results and described the method used to obtain information, information source, document format and communication method, PrEP modality, and intended audience. Documents were converted to plain text for the analysis and readability of the collected documents was assessed using 4 readability indices. We conducted pairwise comparisons of readability based on how the PrEP document was obtained on the web, information source, document format, communication method, PrEP modality, and intended audience, then adjusted for multiple comparisons. RESULTS: A total of 463 documents were identified. Overall, the readability of web-based PrEP information was at a higher level (10.2-grade reading level) than what is recommended for health information provided to the general public (ninth-grade reading level, as suggested by the Department of Health and Human Services). Brochures (n=33, 7% of all identified resources) were the only type of PrEP materials that achieved the target of ninth-grade reading level. CONCLUSIONS: Web-based PrEP information is often written at a complex level for potential and current PrEP users to understand. This may hinder PrEP uptake for some people who would benefit from it. The readability of PrEP-related information found on the web should be improved to align more closely with health communication guidelines for reading level to improve access to this important health information, facilitate informed decisions by those with a need for PrEP, and realize national prevention goals for PrEP uptake and reducing new HIV infections in the United States.

Rural pensions, intra-household bargaining, and elderly medical expenditure in China.

China's rural elderly spend less on medical expenditures as they age despite declining health, raising welfare concerns. This paper investigates the role of intrahousehold bargaining power on health expenditures of the elderly by evaluating the impact of cash transfers from a new social pension program. The program provided windfall payments to those above age 60, making it possible to employ a regression discontinuity design based on age of eligibility to estimate causal effects. Using data from the 2011 and 2013 waves of the China Health and Retirement Longitudinal Study, we find that receiving pension payments increases both the utilization of outpatient care and outpatient expenditures by the elderly who experienced illness. This result is robust to controlling for total household expenditures per capita, ruling out income effects as the main channel. Consistent with pensions increasing elderly bargaining power, we find that pensions significantly increase medical expenditures only for those elderly who co-reside with children or grandchildren but have no effect on those who live independently.

Comparing Aerosol Generation in Human and Animal Tissues During Common Otolaryngology Procedures.

OBJECTIVE: To determine whether hamster and human tissues generate similar amounts of aerosolized particles using common otolaryngology surgical techniques. STUDY DESIGN: Quantitative experimental research. STUDY SETTING: University research laboratory. METHODS: Drilling, electrocautery, and coblation were performed on human and hamster tissues. Particle size and concentration were measured during the surgical procedures using a scanning mobility particle sizer and an aerosol particle sizer (SMPS-APS) and GRIMM aerosol particle spectrometer. RESULTS: SMPS-APS and GRIMM measurements detected at least 2-fold increases in aerosol concentrations compared to baseline during all procedures. Procedures performed on human and hamster tissues produced similar trends and order of magnitude of aerosol concentrations. Generally, hamster tissues produced higher aerosol concentrations compared to human tissues, and some of these differences were statistically significant. Mean particle sizes for all procedures were small (<200 nm), although statistically significant differences in particle size were identified between human and hamster tissues during coblation and drilling. CONCLUSION: Aerosol-generating procedures performed on human and hamster tissue produce similar trends in aerosol particle concentrations and sizes, although we observed some differences between the 2 tissue types. Further studies should be performed to understand the clinical significance of these differences.

Adenylyl cyclase 6 plays a minor role in the mouse inner ear and retina.

Adenylyl cyclase 6 (AC6) synthesizes second messenger cAMP in G protein-coupled receptor (GPCR) signaling. In cochlear hair cells, AC6 distribution relies on an adhesion GPCR, ADGRV1, which is associated with Usher syndrome (USH), a condition of combined hearing and vision loss. ADGRV1 is a component of the USH type 2 (USH2) protein complex in hair cells and photoreceptors. However, the role of AC6 in the inner ear and retina has not been explored. Here, we found that AC6 distribution in hair cells depends on the USH2 protein complex integrity. Several known AC6 regulators and effectors, which were previously reported to participate in ADGRV1 signaling in vitro, are localized to the stereociliary compartments that overlap with AC6 distribution in hair cells. In young AC6 knockout (Adcy6-/-) mice, the activity of cAMP-dependent protein kinase, but not Akt kinase, is altered in cochleas, while both kinases are normal in vestibular organs. Adult Adcy6-/- mice however exhibit normal hearing function. AC6 is expressed in mouse retinas but rarely in photoreceptors. Adcy6-/- mice have slightly enhanced photopic but normal scotopic vision. Therefore, AC6 may participate in the ADGRV1 signaling in hair cells but AC6 is not essential for cochlear and retinal development and maintenance.

A Cross-Sectional Survey of Pediatric Infectious Disease Physicians' Approach to Congenital Cytomegalovirus Infection.

Congenital cytomegalovirus (cCMV) continues to be a major public health care issue due to its high prevalence throughout the world. However, there is a paucity of studies evaluating how providers manage this infection. This study surveyed North American Pediatric Infectious Disease (PID) physicians to elicit their approach towards the evaluation and treatment of this condition. Thirty-two PID physicians responded to this survey. Institutional testing and screening for cCMV were infrequently reported. The respondents in general agreed upon most laboratory and diagnostic testing except for neuroimaging. For those tests, there was a disparity in indications for head ultrasound versus brain MRI imaging. Most (68.8%) agreed with the clinical practice of starting valganciclovir in an infant less than 1 month of age with one sign or symptom of disease, and 62.5% would do so for an infant with isolated sensorineural hearing loss. However, only 28.1% would treat cCMV-infected infants older than 1 month of age. In conclusion, few healthcare institutions represented by PID physicians in this cohort had a cCMV screening or testing initiative, yet most respondents would test at a much higher level based on their clinical practice. While there is general consensus in evaluation and treatment of these children, there are disparities in practices regarding neuroimaging and indications for antiviral treatment with respect to age and severity of disease. There is a great need for an evidence based policy statement to standardize cCMV workup and treatment.

Analysis of an Expanded Targeted Early Cytomegalovirus Testing Program.

OBJECTIVE: Determine the detection rate from an expanded targeted early cytomegalovirus (CMV) testing program implemented from a large healthcare system (Intermountain Healthcare, IHC). STUDY DESIGN: Retrospective review. SETTING: Tertiary medical center. METHODS: An electronic system was modified to include indications for testing whenever a provider placed an order for CMV testing. A retrospective analysis of this database was performed. RESULTS: From March 1, 2021 to August 31, 2022, there were 3450 (8.8%) patients who underwent CMV testing out of 39,245 total live births within the IHC system. Since the formal implementation of this program in 2019, annual CMV testing has increased almost 10-fold: 2668 CMV tests were performed in 2021 compared to 289 CMV tests in 2015. The most frequent indication for congenital CMV (cCMV) testing was small for gestational age (SGA) (68.2%), followed by macrocephaly (13.5%), an abnormal hearing test (5.0%), and microcephaly (4.4%). Fourteen cCMV-infected infants were diagnosed all of them meeting the criteria for symptomatic cCMV. The most common indication resulting in a positive diagnosis was those who presented with SGA (n = 10 patients). The positivity rate would result in a prevalence of 35.7 symptomatic cCMV cases diagnosed per 100,000 live births, numbers comparable to those expected for universal cCMV screening. CONCLUSION: An expanded targeted early cCMV testing program may improve detection rates of symptomatic cCMV cases and should be considered as a feasible alternative approach to universal or hearing-targeted early CMV testing.

Examining thematic and emotional differences across Twitter, Reddit, and YouTube: The case of COVID-19 vaccine side effects.

Social media discourse has become a key data source for understanding the public's perception of, and sentiments during a public health crisis. However, given the different niches which platforms occupy in terms of information exchange, reliance on a single platform would provide an incomplete picture of public opinions. Based on the schema theory, this study suggests a 'social media platform schema' to indicate users' different expectations based on previous usages of platform and argues that a platform's distinct characteristics foster distinct platform schema and, in turn, distinct nature of information. We analyzed COVID-19 vaccine side effect-related discussions from Twitter, Reddit, and YouTube, each of which represents a different type of the platform, and found thematic and emotional differences across platforms. Thematic analysis using k-means clustering algorithm identified seven clusters in each platform. To computationally group and contrast thematic clusters across platforms, we employed modularity analysis using the Louvain algorithm to determine a semantic network structure based on themes. We also observed differences in emotional contexts across platforms. Theoretical and public health implications are then discussed.

Hearing Outcomes in Failed Newborn Hearing Screening Infants With and Without Chronic Serous Otitis.

OBJECTIVE: To identify outcomes in hearing loss (HL) diagnosis and intervention in infants with a failed newborn hearing screen (NBHS) and otitis media with effusion (OME) compared to those with failed NBHS and without OME. STUDY DESIGN: Retrospective review. SETTING: Tertiary medical center. METHODS: A chart review was performed on infants referred to Primary Children's Hospital for failed NBHS from 2012 to 2018. Eighty infants with failed NBHS and OME and 55 with failed NBHS and no OME were included. Incidence of permanent HL along with the age of HL confirmation and early intervention (EI) enrollment were compared. RESULTS: The incidence of OME in infants with failed NBHS was 59.3%. Fifty-six percent of infants with OME and 12.5% of those without OME did not receive definitive hearing confirmation in either ear due to loss to follow-up or insufficient audiometric assessment. Permanent HL was identified in 11.3% (n = 9) of infants with OME and in 20.0% (n = 11) of those without OME. Infants with OME were significantly older at the time of HL confirmation (4.2 ± 2.1 months) and EI enrollment (5.4 ± 2.5 months) compared to those without OME at the time of HL confirmation (1.0 ± 1.0 months; p < .001) and EI enrollment (2.6 ± 1.8 months; p = .04). CONCLUSION: Infants with failed NBHS and OME are highly susceptible to a significant delay in HL confirmation or lack of confirmatory hearing tests. Timely OME resolution with earlier ventilation tube insertion by 3 months of age and follow-up audiologic assessment is recommended.

The cost-effectiveness of targeted screening for congenital cytomegalovirus in newborns compared to clinical diagnosis in the US.

OBJECTIVE: Congenital cytomegalovirus (cCMV) is the leading environmental cause of hearing loss (HL) among children, affecting four in one thousand newborns. cCMV testing in the US is currently based on clinical diagnosis which does not consistently identify cCMV cases and precludes early intervention to prevent and reduce the severity of HL. We estimated the cost-effectiveness of targeted newborn screening and cCMV testing among newborns compared to clinical diagnosis. METHODS: We use a decision-analytic model to estimate the costs of preventing HL progression, of additional cases of severe HL, of identifying a case of HL one year earlier, and of identifying an additional case of cCMV, through targeted screening and cCMV testing for infants failing two newborn hearing screens with follow-up to age five. We also estimate the costs of nationwide implementation of a newborn screening and testing program. Model pathways were based on best practices for screening, testing, and treatment. Probabilities were drawn from the published literature; costs were estimated based on Medicare reimbursement rates. Probabilistic and scenario analyses were conducted to determine the robustness of results. RESULTS: Targeted testing and cCMV screening, compared to standard of care, cost an additional $2.96 (±2.26) per infant screened and identified 0.00038 (±0.00022) cases of HL, 3.8 in 10000 children, at a cost of $8197 (±4217) per case of HL identified. Implementing targeted screening for all children in the US was estimated to cost $193,229. CONCLUSIONS: Although cases numbers are small, our model shows that targeted newborn screening and cCMV testing reduced cases of HL progression. Adoption of newborn targeted screening as standard of care should be considered given it may prevent disability at very low cost.
