"But then that's another barrier": A qualitative study of parent and provider perspectives on rural versus urban disparities in adolescent vaccination.

PURPOSE: Vaccination rates are significantly lower among adolescents living in rural areas compared to those living in urban areas. The objective of this study was to understand the factors contributing to disparities in vaccination between adolescents in rural compared to urban areas. METHODS: Semi-structured qualitative interviews were conducted with parents and providers in 16 rural and 4 urban counties of Colorado. Interview questions followed the socioecological model of health and addressed personal, interpersonal, community, and environment/structural barriers and facilitators that impact adolescent vaccination rates. Qualitative content analysis with a directed content analysis approach was used. Urban and rural interviews were compared to identify barriers unique to rural communities. FINDINGS: Reported barriers included lack of vaccine access at primary care, lack of routine preventive care utilization, the need to take off time from work and school, and misinformation about vaccines. Barriers that were unique to rural communities included structural barriers such as lack of evening and weekend appointments, providers not stocking vaccines, short provider tenures, and costs; logistical barriers such as the need for multiple visits to multiple locations and distance and travel time; and beliefs and behaviors such as an overreliance on sports physicals (in lieu of preventive visits) and natural lifestyle cultures. CONCLUSIONS: There are unique challenges to adolescent vaccination in rural areas that contribute to fewer adolescents receiving their recommended vaccines. Addressing structural barriers may address this disparity.

Single-molecule tracking reveals dynamic regulation of ribosomal scanning.

How eukaryotic ribosomes traverse messenger RNA (mRNA) leader sequences to search for protein-synthesis start sites remains one of the most mysterious aspects of translation and its regulation. While the search process is conventionally described by a linear "scanning" model, its exquisitely dynamic nature has restricted detailed mechanistic study. Here, we observed single Saccharomyces cerevisiae ribosomal scanning complexes in real time, finding that they scan diverse mRNA leaders at a rate of 10 to 20 nt s-1. We show that specific binding of a protein to its mRNA leader sequence substantially arrests scanning. Conversely, impairing scanning-complex guanosine 5'-triphosphate hydrolysis results in native start-site bypass. Our results illustrate an mRNA-centric, kinetically controlled regulatory model where the ribosomal pre-initiation complex amplifies a nuanced energetic landscape to regulate scanning and start-site selection fidelity.

Health Care Delivery Site- and Patient-Level Factors Associated With COVID-19 Primary Vaccine Series Completion in a National Network of Community Health Centers.

Objectives. To assess multilevel factors associated with variation in COVID-19 vaccination rates in a US network of community health centers. Methods. Using multilevel logistic regression with electronic health record data from ADVANCE (Accelerating Data Value Across a National Community Health Center Network; January 1, 2022-December 31, 2022), we assessed associations between health care delivery site-level (n = 1219) and patient-level (n = 1 864 007) characteristics and COVID-19 primary vaccine series uptake. Results. A total of 1 337 440 patients completed the COVID-19 primary vaccine series. Health care delivery site characteristics were significantly associated with lower series completion rates, including being located in non-Medicaid expansion states and isolated or rural communities and serving fewer patients. Patient characteristics associated with significantly lower likelihood of completing the vaccine series included being Black/African American or American Indian/Alaska Native (vs White), younger age, lower income, being uninsured or publicly insured (vs using private insurance), and having fewer visits. Conclusions. Both health care delivery site- and patient-level factors were significantly associated with lower COVID-19 vaccine uptake. Community health centers have been a critical resource for vaccination during the pandemic. (Am J Public Health. 2024;114(11):1242-1251. https://doi.org/10.2105/AJPH.2024.307773).

Perceived Effects of COVID-19 on Vaccine Hesitancy and Clinician Discussion: A Qualitative Study.

BACKGROUND AND OBJECTIVES: Studies note a high prevalence of pediatric coronavirus disease 2019 (COVID-19)-specific vaccine hesitancy in the United States. Our objective was to assess whether clinicians perceive a spillover effect of COVID-19 vaccine hesitancy onto other vaccines, and the impact of this spillover on their general recommendation behavior. METHODS: We conducted semistructured interviews with pediatricians in California and Colorado pediatric practices (January-March 2023). We transcribed, coded, and analyzed interviews using content analysis. RESULTS: We interviewed 21 pediatricians (10 in California, 11 in Colorado). Clinicians observed some spillover effect of vaccine-favorable changes among some parents and greater hesitancy among others regarding the risks and benefits of childhood vaccination in general. This spillover was informed by 2 divergent patterns of parental trust in health systems and individual clinicians caused by the COVID-19 pandemic. Factors driving perceived changes included media coverage, greater knowledge about vaccination, and misinformation. Some clinicians felt that their approach to vaccine recommendations became more patient-centered, whereas others reported declining engagement in persuading hesitant parents about vaccination. CONCLUSIONS: Clinicians described a hardening of parental views toward vaccines in both directions, which impacted their recommendation behavior. There is a need for vaccine hesitancy monitoring and better training and support for clinicians facing vaccine hesitant parents.

Pediatric Coronavirus Disease 2019 Vaccine Experiences, Practices, and Attitudes in Rural Primary Care Clinicians.

OBJECTIVE: Pediatric coronavirus disease 2019 (COVID-19) vaccination rates remain low in rural areas. A strong clinician recommendation improves vaccine uptake, but the pediatric COVID-19 vaccine recommendation practices of rural primary care clinicians have not been reported. Our objectives were to describe, among rural Colorado pediatric clinicians: 1) recommendation practices for COVID-19 vaccine compared to influenza and school-entry required vaccines, and 2) personal attitudes. METHODS: From July to October 2023, surveys were distributed to clinicians in rural Colorado identified as pediatric vaccine providers in counties designated as rural through the Colorado Immunization Information System using mail and email. RESULTS: Of 89 survey respondents, 37% of clinicians strongly recommended COVID-19 vaccines for children 6 months-5 years old, compared to 79% for influenza (P = 0.05) and 92% for school-entry required vaccines (P = 0.04). For children 6-11 and 12-17 years old, 43% and 44% of clinicians strongly recommended COVID-19 vaccines, respectively, compared to 71% and 70% for influenza (P < 0.01), and 91% for school-entry required vaccines (P < 0.01). Forty four percent of clinicians agreed that COVID-19 vaccines are important for pediatric patients. The most common clinician-perceived challenges to discussing pediatric COVID-19 vaccines included a lack of parent interest in more information (76% "somewhat" or "strongly" agree), lack of ability to change parents' minds (71%), and concerns that the vaccines are too political (40%). CONCLUSIONS: Most rural Colorado clinicians do not strongly recommend pediatric COVID-19 vaccines compared to influenza and school-entry required vaccines. Efforts to improve pediatric COVID-19 vaccine uptake should aim to strengthen clinicians' recommendations of these vaccines.

Global neurotrauma: A systematic review and summary of the current state of registries around the world.

Neurotrauma registries (NTR) collect data on traumatic brain injuries (TBI) to advance knowledge, shape policies, and improve outcomes. This study reviews global NTRs from High-Income (HICs) and Low- and Middle-Income countries (LMICs). A systematic review was conducted using PubMed, Google Scholar, Embase, and Web of Science following PRISMA guidelines to identify relevant NTRs. Twenty-six articles were included, revealing ten different NTRs from Europe, North America, Latin America, the Middle East, and Asia. North America had the most registries at four, followed by Europe and Asia with two each, and Latin America and the Middle East with one each. The median database size was 1,734 patients (Range: 65-25,000), with the largest registry from the United States (FITBIR DB) and the smallest from Iran (NSCIR-IR). The longest data collection period was 32 years, with a mean age of 43.1 years (Range: 9.07-60.0). Males comprised 70 % of patients. Sixty-six percent of articles emphasized outcomes such as functionality, length of stay, and mortality. Key challenges identified included issues with missing data and incomplete records (n = 4), lack of standardization in data collection procedures (n = 3), staffing shortages (n = 5), lack of IT infrastructure (n = 3), and problems with reproducibility, particularly in high-income countries (n = 4). Our review highlights the need for a large-scale global NTR, addressing LMIC barriers through private-public partnerships with organized neurosurgery members.

Alternative hybrid access in endovascular neurosurgery: Scoping review and technical considerations.

BACKGROUND: The common femoral artery and radial artery constitute the most common access sites in contemporaneous endovascular neurosurgery. Oftentimes, it may be impossible to reach the vascular target safely due to different circumstances, necessitating alternative approaches. We aim to review these "last resource" access sites described in the literature, focusing on the technical aspects as a convenient reference. METHODS: We performed a comprehensive literature search of PubMed capturing articles from 1958 to 2022. RESULTS: We identified nine alternative approaches for endovascular access, after excluding direct carotid stick: superficial temporal artery access in 60 patients, calvarial foramina access in five patients, occipital artery access in seven patients, middle meningeal artery access in six patients, vertebral artery access in 23 patients and external carotid artery, internal maxillary artery, facial artery or lingual artery in 40 patients. Indications for the use of alternative access points included tortuous or occluded vessels, small vessel calibers, or anatomic variation. Pathologies treated included dural arteriovenous fistulas, arteriovenous malformations, intracranial aneurysms, acute stroke, and intracranial stenosis. Diagnostic brain angiograms were also performed. CONCLUSIONS: Alternative vascular access routes expand the proceduralists' toolkit, enhancing the capability to manage complex cerebrovascular interventions. This review advocates for a broader understanding and consideration of these techniques, given their potential to significantly increase treatment options in neuroendovascular surgery.

Multilevel approaches to immunization equity.

This review provides a multilevel framework for understanding vaccination disparities and provides examples of work addressing disparities risk factors and building immunization equity. Readers will review the World Health Organization's 2023 priorities for vaccination equity, learn about vaccination campaigns in conflict zones like Ukraine, identify key components to a successful COVID-19 response in Ghana, and understand Brazilian efforts to minimize stigma and champion community members to build trust in mpox vaccines and health services. These efforts will improve equity and foster flourishing among vulnerable populations.

Acute vision changes as the presenting symptom of ocular syphilis - A case series of two.

Introduction: Syphilis, a bacterial infection caused by Treponema pallidum, can affect a wide variety of organ systems of its host. We aim to present the cases of two patients who presented to an urban, tertiary care, academic Emergency Department with ocular symptoms who underwent imaging, laboratory, and specialist evaluation and were ultimately diagnosed with ocular syphilis. Case Report: The first patient is a 46-year-old female who presented to the Emergency Department with painless complete vision loss in a unilateral eye. Her exam was significant for bilateral papilledema, and further workup revealed a retinal detachment in the affected eye. Rapid plasma reagin (RPR) titers resulted positive with 1:128 and a reactive fluorescent treponemal antibody (FTA). Further workup including lumbar puncture and magnetic resonance imaging were unable to be obtained due to patient refusal and multiple discharges against medical advice. The second patient is a 38-year-old female with a history of intravenous drug use who presented for bilateral circumferential peripheral vision loss with central sparing. The examination showed bilateral papilledema. Lumbar puncture was performed with normal intracranial pressure. RPR titers resulted positive with 1:128. MRI and ophthalmology evaluation did not reveal any other etiology or explanation for papilledema. Conclusion: This case series highlights the importance of considering syphilis as a possible cause of ocular symptoms in high risk patient populations and the need for prompt and appropriate treatment given the increasing prevalence of syphilis worldwide.

Rare Aneurysmal Bone Cyst Presentation in the Orbit: A Systematic Review of the Literature with an Illustrative Case Report.

OBJECTIVE: Aneurysmal bone cysts (ABCs) are benign but aggressive vascular lesions within bone. Orbital ABCs, though rare, are clinically significant due to the risk of debilitating symptoms such as vision loss. METHODS: Our systematic review was conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines using PubMed, Google Scholar, Embase, and SCOPUS databases to identify and assess primary articles exploring orbital ABC cases. Additionally, we present an illustrative case report. RESULTS: Among the 54 cases from the 51 studies included, the mean age was 16.87 years, with 23 males, 29 females, and 2 unspecified. The most prevalent symptoms were exophthalmos (N = 36) and diplopia (N = 21). Regarding laterality, the right orbit was most commonly affected (N = 27), followed by the left orbit (N = 21), with 4 cases of bilateral involvement. Within the orbit, the medial wall most frequently impacted location (N = 14), followed by the orbital roof (N = 13), posterior wall (N = 7), lateral wall (N = 3), and orbital floor (N = 2), with 15 cases involving multiple locations. Surgical resection was the primary treatment, resulting in complete resolution in 44 cases. In our case, a 30-year-old male with an orbital ABC was managed surgically through bifrontal craniotomy with superior orbitotomy for lesion excision and orbital roof reconstruction. CONCLUSIONS: ABCs in the orbit can be challenging, and complete removal of the lesion is essential for achieving optimal patient outcomes.

Diverticulosis and Diverticulitis on YouTube: Is Popular Information the Most Reliable?

Background Patients utilize online health information to inform their medical decision-making. YouTube is one of the most popular media platforms with abundant health-related resources, yet the quality of the disseminated information remains unclear. This study aims to evaluate the quality and reliability of content pertaining to diverticulosis and diverticulitis on YouTube. Methods One author queried the terms "diverticulosis," "diverticulitis," "acute diverticulitis," and "chronic diverticulitis" on YouTube. The first 50 videos per search were selected for analysis. Duplicates, non-English videos, or procedural content were excluded. Video characteristics including view count, likes, comments, duration, days since upload, view ratio, video power index, and video sources (professional organizations (POs), health information websites (HIWs), and entertainment/independent users (EIUs)) were collected. Videos were scored using the mDISCERN and Global Quality Score (GQS). Results Sixty-four videos were included. DISCERN scores significantly differed between POs (n=20, mean=4.35), HIWs (n=29, mean=2.97), and EIUs (n=15, mean=1.83). GQS also significantly differed between POs (n=20, mean=4.47), HIWs (n=29, mean=3.62), and EIUs (n=15, mean=2.5). Video characteristics significantly differed between groups, with most user engagement seen in EIUs. Conclusion POs and HIWs disseminate higher quality health information about diverticular disease on YouTube. The higher viewer engagement with EIUs is concerning, as these sources were found to have lower quality content. Although YouTube has the capability to provide valuable information on diverticulosis and diverticulitis, enhanced content screening is needed to ensure accuracy and validation.

June 2024 ACIP Meeting Update: Influenza, COVID-19, RSV, and Other Vaccines.

The Advisory Committee on Immunization Practices (ACIP), a group of medical and public health experts that provides advice to the Centers for Disease Control and Prevention, normally meets 3 times per year to develop US vaccine recommendations. The ACIP met June 26 through 28, 2024. This update summarizes the proceedings of this meeting, with an emphasis on topics that are most relevant to the pediatric population. Major updates for pediatric clinicians include COVID-19 and influenza vaccine recommendations for the 2024 to 2025 season, meningococcal vaccination considerations, information regarding preferred Haemophilus influenzae type B containing vaccines for American Indian and Alaskan Native infants, and updates regarding implementation and effectiveness of RSV immunization in pregnant people and infants.

Natural history of shedding and household transmission of severe acute respiratory syndrome coronavirus 2 using intensive high-resolution sampling.

IMPORTANCE: The COVID-19 pandemic has led to 775 million documented cases and over 7 million deaths worldwide as of March 2024 and is an ongoing health crisis. To limit viral spread within households and in the community, public health officials have recommended self-isolation, self-quarantine of exposed household contacts, and mask use. Yet, risk of household transmission (HHT) may be underestimated due to low frequency of sampling, and risk factors for HHT are not well understood. OBJECTIVES: To estimate the secondary attack rate of SARS-CoV-2 within households and to define the risk factors for new infections in household members who are in close contact with the index case. DESIGN, SETTING, AND PARTICIPANTS: In this prospective cohort study, from March 2020-December 2021 we enrolled 60 households with index cases who tested positive for SARS-CoV-2. All household contacts and index cases were tested daily for SARS-CoV-2 via reverse transcription polymerase chain reaction (RT-PCR) using self-collected anterior nares specimens. Households were followed until all study participants in the household tested negative for SARS-CoV-2 for seven consecutive days. We collected sex, age, race/ethnicity, comorbidities, and relationship to index case for secondary contacts, household level characteristics including primary income, household density, and square feet per person on property. We compared the sociodemographic variables between COVID-19 positive and negative household members and between households where secondary transmission did and did not occur. MAIN OUTCOMES AND MEASURES: Daily anterior nares swabs were tested for SARS-CoV-2 using RT-PCR, in order to assess duration of nasal shedding of SARS-CoV-2, as well as risk of transmission to secondary household contacts. RESULTS: Of the 163 participants in this study, 84 (51.5%) were women; median age (IQR) was 36.0 (17.0-54.0) years of age; 78 (47.8%) were white and 48 (29.5%) were Hispanic/LatinX. Of the fifty households with household contacts, at least one secondary case occurred in twenty-six households (52.0%) and forty-five household contacts (43.7%) were infected. Secondary attack rate was lowest among children of index cases (6/23, 26.1%). Modified Poisson regression identified that the risk of transmission to household contacts increases significantly with age (Risk ratio for each increase in years of age = 1.01, 95% CI = 1.00-1.02). Mixed effects regression models identified that participants with chronic diseases, such as asthma, diabetes, cancer, or cardiac disease, had higher Cts at baseline when compared to participants without chronic diseases (6.62, 95% CI: 1.46-11.77, p = 0.02) and show a slower rate of increase in Ct over time (-0.43, 95% CI: -0.77 to -0.09, p = 0.02). CONCLUSIONS AND RELEVANCE: This study suggests that HHT represents a key source of community-based infection of SARS-CoV-2. Allocation of resources for contact investigations and prevention interventions should focus on the individuals at highest risk of infection in households, especially those with higher density homes.

Antibiotic use and class absenteeism in children with influenza-like-illness in an emergency department.

BACKGROUND: Children with influenza-like-illness (ILI) often require clinician clearance or antibiotics to return to child care or school. Study objectives were to examine the association between antibiotic receipt during an Emergency Department (ED) visit for ILI and the outcomes of class absenteeism and illness duration. METHODS: A secondary analysis of 251 children aged 2 months to 12 years with uncomplicated ILI discharged from the ED from December 1, 2018 to November 30, 2019 was conducted. The primary exposure was receipt of antibiotics over the course of illness (assessed by chart review and family follow-up survey). RESULTS: Patients prescribed antibiotics (n = 65) experienced a median of 3 (interquartile range [IQR]: 1,5) days of class missed and 5 (IQR: 3,7) days of illness compared to 2 (IQR: 1,4) days of class missed and 4 (IQR: 3,7) days of illness for those not prescribed antibiotics (n = 186, p = 0.08 and p = 0.13, respectively). There was no statistically significant association with missed class days (incidence rate ratio [IRR]: 1.14 [0.86-1.50], p = 0.37) or days of illness (IRR: 1.06 [0.88-1.27], p = 0.55) for patients prescribed antibiotics compared to patients not prescribed antibiotics for ILI. CONCLUSIONS: Antibiotic use for ILI was not associated with reduced class absenteeism or illness duration. IMPACT STATEMENT: Child care centers and schools sometimes exclude children with influenza-like-illness (ILI) from class until cleared to return by a clinician and/or prescribed antibiotics. This study addresses these social drivers of overprescribing. Antibiotics were prescribed in 26% of children with ILI discharged from a large Emergency Department in the US. Antibiotic use was not significantly associated with class absenteeism or illness duration. This study can serve as a discussion point for clinicians when navigating parental or social pressures to prescribe antibiotics for uncomplicated acute respiratory tract infections, particularly when these pressures are influenced by concerns about returning to class.

A World without Measles and Rubella: Addressing the Challenge of Vaccine Hesitancy.

The worldwide elimination of measles and rubella is feasible, but not without overcoming the substantial challenge of vaccine hesitancy. This challenge is complicated by the spread of misinformation and disinformation fueled by rapidly progressing technologies and evolving forms of online communication. The recent COVID-19 pandemic has only added further complexity to this challenge. However, considerable progress has been made in understanding the scope of the problem and the complex factors that influence vaccine hesitancy. Our understanding of evidence-based strategies for addressing vaccine hesitancy has grown significantly, including evidence for effective communication and behavioral interventions. In this article, we review measles and rubella vaccines and vaccine hesitancy. We then provide an overview of evidence-based strategies for addressing vaccine hesitancy, including communication strategies and behavioral interventions. This article is relevant to healthcare professionals, health system leaders, public health professionals, policymakers, community leaders, and any individuals who have a role in addressing vaccine hesitancy in their communities. Finally, we review future directions and major areas of research need.

Risk Factors for Pediatric Intracranial Neoplasms in the Kids' Inpatient Database.

INTRODUCTION: In children and adolescents, brain and central nervous system (CNS) tumors are the leading types of cancers. Past studies have found differing rates of intracranial cancers among races and identified additional cancer risk factors. This study aimed to see if these differences can be substantiated with further investigation of the latest version (2019) of the Kids' Inpatient Database (KID). METHODS: A total of 7,818 pediatric patients <21 years old in KID with ICD-10 codes consisting of malignant neoplasms of the brain, brainstem, and cerebral meninges (C700, C709-C719) were queried. Modifiable risk factors evaluated include: hospital region, insurance type, hospital city size, the average income of patient zip code, and location/teaching status of a hospital. Non-modifiable risk factors were race and sex at birth. Dependent variables were tested in Excel and GraphPad Prism 9 using a χ2 test with Yates' continuity correction and Tukey's one-way and two-way ANOVAs. RESULTS: Mortality rates of females (2.88%) compared to males (1.99%) were significant (p < 0.05). Mortality was (4.17%) in black patients compared to (1.68%) for white (p < 0.0001), Hispanic mortality (2.95%) compared to white (p < 0.01), and mortality of Asian/Pacific Islander (3.86%) compared to white (p < 0.01). Black patients had significantly higher mortality than white, Hispanic, Asian/Pacific Islander, Native American, and other races overall (p < 0.01). There was no significant difference in the mortality rates between children's hospitals and large hospitals for any race. After accounting for patient race, mortality was still not significantly different for patients with Medicaid insurance compared to non-Medicaid insurance types. Of the children treated at children's hospitals, the most transferred in from outside hospitals were Native American (20.00%) followed by Asian/Pacific Islander (15.09%) then Hispanic patients (13.67%). A significant difference between races was also seen regarding length of stay (p < 0.001) and number of charges (p < 0.001). CONCLUSION: These findings confirm prior studies suggesting gender and race are significant factors in mortality rates for children with intracranial neoplasms. However, the findings do not identify the root causes of these discrepancies but may serve as an impetus for clinicians, healthcare administrators, and governmental leaders to improve national resource allocation to better care for pediatric patients with intracranial neoplasms.
