Food allergies, food sensitivities, and adverse reactions to food represent common reasons for gastroenterology and allergy referral. The epidemiology of these disorders is changing; food allergies are more common than previously thought, and there is a heightened sense of awareness about food sensitivities. Symptoms do not always accurately predict the underlying pathophysiology nor distinguish the underlying etiology. This may lead to unnecessary testing, which is often unrewarding and expensive. Myths and misconceptions about food allergies and sensitivities are common and may lead to unwarranted treatment using untested therapies. Importantly, a missed diagnosis of a true food allergy can have serious consequences. This article discusses the differences between food allergies and sensitivities, including their epidemiology, underlying pathophysiology, key symptoms, and diagnostic criteria, as well as their treatment options.

Social media is widely used globally by patients, families of patients, health professionals, scientists, and other stakeholders who seek and share information related to cancer. Despite many benefits of social media for cancer care and research, there is also a substantial risk of exposure to misinformation, or inaccurate information about cancer. Types of misinformation vary from inaccurate information about cancer risk factors or unproven treatment options to conspiracy theories and public relations articles or advertisements appearing as reliable medical content. Many characteristics of social media networks—such as their extensive use and the relative ease it allows to share information quickly—facilitate the spread of misinformation. Research shows that inaccurate and misleading health‐related posts on social media often get more views and engagement (e.g., likes, shares) from users compared with accurate information. Exposure to misinformation can have downstream implications for health‐related attitudes and behaviors. However, combatting misinformation is a complex process that requires engagement from media platforms, scientific and health experts, governmental organizations, and the general public. Cancer experts, for example, should actively combat misinformation in real time and should disseminate evidence‐based content on social media. Health professionals should give information prescriptions to patients and families and support health literacy. Patients and families should vet the quality of cancer information before acting upon it (e.g., by using publicly available checklists) and seek recommended resources from health care providers and trusted organizations. Future multidisciplinary research is needed to identify optimal ways of building resilience and combating misinformation across social media. [ABSTRACT FROM AUTHOR]

Simple Summary: Immune checkpoint blockade has shown remarkable efficacy across various cancers but has failed to improve outcomes in patients with relapsed medulloblastoma (MB). While it is thought that the cold, immunosuppressive tumor microenvironment of MB accounts for this poor efficacy, the precise mechanisms contributing to immune suppression in this context remain unclear. In this study, we explore the immune landscape of MB using a previously unexplored syngeneic mouse model. Our study demonstrates that this model faithfully recapitulates the cold, immunosuppressive tumor microenvironment observed in human disease. Importantly, our research uncovers mechanisms employed by myeloid cells and tumor cells to evade immune detection while highlighting the therapeutic potential of targeting V-domain Ig Suppressor of T-cell Activation (VISTA), a novel inhibitory immune checkpoint, to enhance anti-tumor immunity. Background: Relapsed medulloblastoma (MB) poses a significant therapeutic challenge due to its highly immunosuppressive tumor microenvironment. Immune checkpoint inhibitors (ICIs) have struggled to mitigate this challenge, largely due to low T-cell infiltration and minimal PD-L1 expression. Identifying the mechanisms driving low T-cell infiltration is crucial for developing more effective immunotherapies. Methods: We utilize a syngeneic mouse model to investigate the tumor immune microenvironment of MB and compare our findings to transcriptomic and proteomic data from human MB. Results: Flow cytometry reveals a notable presence of CD45hi/CD11bhi macrophage-like and CD45int/CD11bint microglia-like tumor-associated macrophages (TAMs), alongside regulatory T-cells (Tregs), expressing high levels of the inhibitory checkpoint molecule VISTA. Compared to sham control mice, the CD45hi/CD11bhi compartment significantly expands in tumor-bearing mice and exhibits a myeloid-specific signature composed of VISTA, CD80, PD-L1, CTLA-4, MHCII, CD40, and CD68. These findings are corroborated by proteomic and transcriptomic analyses of human MB samples. Immunohistochemistry highlights an abundance of VISTA-expressing myeloid cells clustering at the tumor–cerebellar border, while T-cells are scarce and express FOXP3. Additionally, tumor cells exhibit immunosuppressive properties, inhibiting CD4 T-cell proliferation in vitro. Identification of VISTA's binding partner, VSIG8, on tumor cells, and its correlation with increased VISTA expression in human transcriptomic analyses suggests a potential therapeutic target. Conclusions: This study underscores the multifaceted mechanisms of immune evasion in MB and highlights the therapeutic potential of targeting the VISTA–VSIG axis to enhance anti-tumor responses.

This research explored baby boomer gay men’s experiences with primary healthcare and their perspectives of future long-term care. Baby boomer gay men’s perspectives about primary healthcare remain understudied in the United States. A descriptive qualitative study was conducted with 30 baby boomer men in the Southwest USA. We used semi-structured interviews to assess participants’ initiation and maintenance of primary healthcare, disclosure of sexual orientation to providers, and perspectives about future healthcare needs, including long-term care. Data were analyzed with a latent thematic analysis. We found baby boomer gay men anticipate discrimination because of their sexual orientation whenever they establish healthcare with new providers. Participants identified circumstantial comfort in the new healthcare setting as a key motivator to disclose their sexual orientation. Thus, baby boomer gay men specifically sought gay or gay-friendly healthcare providers to ease the burden of managing disclosure and to permit free discussion of their sexual orientation and healthcare needs. Participants faced recurring anticipation of rejection and discrimination from healthcare providers, which extends to their perceptions of current healthcare encounters and future long-term care placement. Healthcare providers would benefit from understanding the practice implications of this dynamic. Future research on primary healthcare inclusivity is needed. [ABSTRACT FROM AUTHOR]

Introduction: Physical activity (PA) has shown great benefits in patients with chronic obstructive pulmonary disease (COPD); however, their PA is below average. Motivational factors associated with PA in COPD have not been widely studied and could be a target for improving adherence to PA. The objective of our study was to identify and understand the different motivational and confidence factors related to low levels of PA in a COPD cohort. Method: Observational, prospective, multicenter study of COPD patients. Sociodemographic data, respiratory symptoms, comorbidities, spirometry, and exercise capacity were collected. PA was measured using the Dynaport accelerometer and patient motivation and confidence in PA were assessed by a questionnaire previously used in a COPD population in the USA. Results: Eighty six COPD patients were included, 68.6% being male, with a mean (SD) age of 66.6 (8.5) years and a mean forced expiratory volume in the first second (%) of 50.9% (17.3%). The mean walking time was 82.8 (37.8) minutes/day. Questions related to health benefits and enjoying exercise were ranked highest in the motivation questionnaire and statistically significant differences were found in PA measures between patients with low and high motivation. A lack of confidence regarding hot weather and health-related issues significantly influenced PA levels. Advice from third parties, including healthcare providers, was not associated with higher PA levels. Conclusions: Improving the health of COPD patients is their main motivation to perform PA. Lack of confidence when it is hot or when they fear for their health is related to low levels of PA. Advice from third parties, including healthcare professionals, is not associated with higher PA. These results are relevant for developing strategies to increase the adherence of COPD patients to PA programs. [ABSTRACT FROM AUTHOR]

Immunoassays designed to detect SARS-CoV-2 protein antigens (Ag) are commonly used to diagnose COVID-19. The most widely used tests are lateral flow assays that generate results in approximately 15 minutes for diagnosis at the point-of-care. Higher throughput, laboratory-based SARS-CoV-2 Ag assays have also been developed. The number of commercially available SARS-CoV-2 Ag detection tests has increased rapidly, as has the COVID-19 diagnostic literature. The Infectious Diseases Society of America (IDSA) convened an expert panel to perform a systematic review of the literature and develop best-practice guidance related to SARS-CoV-2 Ag testing. This guideline is an update to the third in a series of frequently updated COVID-19 diagnostic guidelines developed by the IDSA. IDSA's goal was to develop evidence-based recommendations or suggestions that assist clinicians, clinical laboratories, patients, public health authorities, administrators, and policymakers in decisions related to the optimal use of SARS-CoV-2 Ag tests in both medical and nonmedical settings. A multidisciplinary panel of infectious diseases clinicians, clinical microbiologists, and experts in systematic literature review identified and prioritized clinical questions related to the use of SARS-CoV-2 Ag tests. A review of relevant, peer-reviewed published literature was conducted through 1 April 2022. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology was used to assess the certainty of evidence and make testing recommendations. The panel made 10 diagnostic recommendations that address Ag testing in symptomatic and asymptomatic individuals and assess single versus repeat testing strategies. US Food and Drug Administration (FDA) SARS-CoV-2 Ag tests with Emergency Use Authorization (EUA) have high specificity and low to moderate sensitivity compared with nucleic acid amplification testing (NAAT). Ag test sensitivity is dependent on the presence or absence of symptoms and, in symptomatic patients, on timing of testing after symptom onset. In most cases, positive Ag results can be acted upon without confirmation. Results of point-of-care testing are comparable to those of laboratory-based testing, and observed or unobserved self-collection of specimens for testing yields similar results. Modeling suggests that repeat Ag testing increases sensitivity compared with testing once, but no empirical data were available to inform this question. Based on these observations, rapid RT-PCR or laboratory-based NAAT remain the testing methods of choice for diagnosing SARS-CoV-2 infection. However, when timely molecular testing is not readily available or is logistically infeasible, Ag testing helps identify individuals with SARS-CoV-2 infection. Data were insufficient to make a recommendation about the utility of Ag testing to guide release of patients with COVID-19 from isolation. The overall quality of available evidence supporting use of Ag testing was graded as very low to moderate. [ABSTRACT FROM AUTHOR]

Accurate molecular diagnostic tests are necessary for confirming a diagnosis of coronavirus disease 2019 (COVID-19) and for identifying asymptomatic carriage of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2). The number of available SARS-CoV-2 nucleic acid detection tests continues to increase as does the COVID-19 diagnostic literature. Thus, the Infectious Diseases Society of America (IDSA) developed an evidence-based diagnostic guideline to assist clinicians, clinical laboratorians, patients, and policymakers in decisions related to the optimal use of SARS-CoV-2 nucleic acid amplification tests. In addition, we provide a conceptual framework for understanding molecular diagnostic test performance, discuss nuances of test result interpretation in a variety of practice settings, and highlight important unmet research needs related to COVID-19 diagnostic testing. IDSA convened a multidisciplinary panel of infectious diseases clinicians, clinical microbiologists, and experts in systematic literature review to identify and prioritize clinical questions and outcomes related to the use of SARS-CoV-2 molecular diagnostics. Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology was used to assess the certainty of evidence and make testing recommendations. The panel agreed on 12 diagnostic recommendations. Access to accurate SARS-CoV-2 nucleic acid testing is critical for patient care, hospital infection prevention, and the public health response to COVID-19 infection. Information on the clinical performance of available tests continues to grow, but the quality of evidence of the current literature to support this updated molecular diagnostic guideline remains moderate to very low. Recognizing these limitations, the IDSA panel weighed available diagnostic evidence and recommends nucleic acid testing for all symptomatic individuals suspected of having COVID-19. In addition, testing is suggested for asymptomatic individuals with known or suspected contact with a COVID-19 case when the results will impact isolation/quarantine/personal protective equipment (PPE) usage decisions. Evidence in support of rapid testing and testing of upper respiratory specimens other than nasopharyngeal swabs, which offer logistical advantages, is sufficient to warrant conditional recommendations in favor of these approaches.

Immunoassays designed to detect SARS-CoV-2 protein antigens are now commercially available. The most widely used tests are rapid lateral flow assays that generate results in ~15 minutes for diagnosis at the point-of-care. Higher throughput, laboratory-based SARS-CoV-2 antigen (Ag) assays have also been developed. The overall accuracy of SARS-CoV-2 Ag tests, however, is not well defined. The Infectious Diseases Society of America (IDSA) convened an expert panel to perform a systematic review of the literature and develop best-practice guidance related to SARS-CoV-2 Ag testing. This guideline is the third in a series of rapid, frequently updated COVID-19 diagnostic guidelines developed by IDSA. IDSA's goal was to develop evidence-based recommendations or suggestions that assist clinicians, clinical laboratories, patients, public health authorities, administrators, and policymakers in decisions related to the optimal use of SARS-CoV-2 Ag tests in both medical and nonmedical settings. A multidisciplinary panel of infectious diseases clinicians, clinical microbiologists, and experts in systematic literature review identified and prioritized clinical questions related to the use of SARS-CoV-2 Ag tests. Grading of Recommendations Assessment, Development, and Evaluation (GRADE) methodology was used to assess the certainty of evidence and make testing recommendations. The panel agreed on 5 diagnostic recommendations. These recommendations address Ag testing in symptomatic and asymptomatic individuals as well as assess single versus repeat testing strategies. Data on the clinical performance of US Food and Drug Administration SARS-CoV-2 Ag tests with Emergency Use Authorization are mostly limited to single, one-time testing versus standard nucleic acid amplification testing (NAAT) as the reference standard. Rapid Ag tests have high specificity and low to modest sensitivity compared with reference NAAT methods. Antigen test sensitivity is heavily dependent on viral load, with differences observed between symptomatic compared with asymptomatic individuals and the time of testing post-onset of symptoms. Based on these observations, rapid reverse transcriptase–polymerase chain reaction (RT-PCR) or laboratory-based NAAT remain the diagnostic methods of choice for diagnosing SARS-CoV-2 infection. However, when molecular testing is not readily available or is logistically infeasible, Ag testing can help identify some individuals with SARS-CoV-2 infection. The overall quality of available evidence supporting use of Ag testing was graded as very low to moderate. [ABSTRACT FROM AUTHOR]

Background Accurate molecular diagnostic tests are necessary for confirming a diagnosis of coronavirus disease 2019 (COVID-19). Direct detection of severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleic acids in respiratory tract specimens informs patient, healthcare institution and public health level decision-making. The numbers of available SARS-CoV-2 nucleic acid detection tests are rapidly increasing, as is the COVID-19 diagnostic literature. Thus, the Infectious Diseases Society of America (IDSA) recognized a significant need for frequently updated systematic reviews of the literature to inform evidence-based best practice guidance. Objective The IDSA's goal was to develop an evidence-based diagnostic guideline to assist clinicians, clinical laboratorians, patients and policymakers in decisions related to the optimal use of SARS-CoV-2 nucleic acid amplification tests. In addition, we provide a conceptual framework for understanding molecular diagnostic test performance, discuss the nuance of test result interpretation in a variety of practice settings and highlight important unmet research needs in the COVID-19 diagnostic testing space. Methods IDSA convened a multidisciplinary panel of infectious diseases clinicians, clinical microbiologists, and experts in systematic literature review to identify and prioritize clinical questions and outcomes related to the use of SARS-CoV-2 molecular diagnostics. Grading of Recommendations Assessment, Development and Evaluation (GRADE) methodology was used to assess the certainty of evidence and make testing recommendations. Results The panel agreed on 17 diagnostic recommendations. Conclusions Universal access to accurate SARS-CoV-2 nucleic acid testing is critical for patient care, hospital infection prevention and the public response to the COVID-19 pandemic. Information on the clinical performance of available tests is rapidly emerging, but the quality of evidence of the current literature is considered moderate to very low. Recognizing these limitations, the IDSA panel weighed available diagnostic evidence and recommends nucleic acid testing for all symptomatic individuals suspected of having COVID-19. In addition, testing is recommended for asymptomatic individuals with known or suspected contact with a COVID-19 case. Testing asymptomatic individuals without known exposure is suggested when the results will impact isolation/quarantine/personal protective equipment (PPE) usage decisions, dictate eligibility for surgery, or inform solid organ or hematopoietic stem cell transplantation timing. Ultimately, prioritization of testing will depend on institutional-specific resources and the needs of different patient populations. [ABSTRACT FROM AUTHOR]

Our objective was to examine the influence of COVID-19 vaccination on recent (i.e., past month) moderate or severe symptoms of anxiety (GAD ‐ 7 ≥ 10) or depression (PHQ ‐ 8 ≥ 10) before and after the COVID-19 vaccine became universally available for adults in the U.S. Participants belonged to the Communities, Households, and SARS-CoV-2 Epidemiology Cohort (CHASING COVID), a national longitudinal study. Our analytic population included 4,832 participants who reported vaccination status from December 2020 to December 2021 with follow-up outcomes assessed through March 2022. We emulated a hypothetical randomized experiment, a target trial, to estimate the effect of COVID-19 vaccination on symptoms of anxiety or depression. Before vaccines were universally available, participants who were vaccinated versus not had significantly lower adjusted odds of symptoms of moderate or severe anxiety (aOR: 0.79; 95% CI: 0.70-0.89). In the universal vaccine era, vaccination was associated with marginally higher adjusted odds of symptoms of moderate or severe anxiety (aOR: 1.23; 95% CI: 1.00-1.50). Vaccination did not influence subsequent moderate or severe depressive symptoms in the preuniversal vaccine era (aOR: 0.92; 95% CI: 0.82-1.03) or universal vaccine era (aOR: 1.11; 95% CI: 0.91-1.36). Research into the longitudinal relationship between COVID-19 vaccination and symptoms of depression and anxiety is warranted, with a focus on advancing understanding of potential mediators on the pathway between vaccination and mental health as well as modifiable factors, such as vaccine hesitancy or vaccine beliefs, that may help identify populations for whom vaccination may be particularly beneficial to their mental health.

Purpose: The purpose of this study is to build a broader framework for Chinese principal leadership and to determine what aspects of principal leadership correlate most highly with school outcomes from the perspectives of both principals and teachers. Method: The data come from a 2013 national student achievement assessment in China comprising 37,749 students in Grade 8 and 9,165 teachers in 613 secondary schools. Adopting Grissom and Loeb's measurement framework, we use both exploratory and confirmatory factor analyses to examine the structure of principal leadership. Then, a hierarchical linear model is employed to analyze the relationship between principal leadership and five school outcomes, controlling for basic student and teacher demographics and certain school context variables. Findings: We identify many differences and some similarities between China and the United States. We obtain five leadership factors from the principals' self-rating data (Visibility and Direct Participation, Instruction Organization, Internal Environment Organization, Planning and Personnel, and External Relations) and three leadership factors from the teachers' rating data (Organization and Management, Instruction and Curriculum, and Visibility and Direct Participation). Regarding student reading achievement and learning efficacy, from both the principals' and teachers' perspectives, the most highly correlated aspect is Instruction Organization. For teachers' occupational stress, job burnout, and teaching efficacy, teachers' ratings of principal leadership exhibit more significant relationships than does principals' self-rated leadership. Implications: We explore a broader framework of principal leadership in China. We identify the benefits and analyze alternative views of the indirect effects of principal leadership on students.

Background: Transgender women (TW) experience significant inequities in healthcare access and health disparities compared to cisgender populations. Access to non-transition related healthcare is understudied among TW. We aimed to assess the association between access to care and gender minority stress and resilience factors among TW living with and without HIV in eastern and southern United States. Methods: This study was a cross-sectional analysis of baseline data drawn from a cohort of 1613 adult TW from the LITE Study. The cohort permitted participation through two modes: a site-based, technology-enhanced mode and an exclusively online (remote) mode. Exploratory and confirmatory factor analyses determined measurement models for gender minority stress, resilience, and healthcare access. Structural equation modeling was used to assess the relationships between these constructs. Models were evaluated within the overall sample and separately by mode and HIV status. Results: Higher levels of gender minority stress, as measured by anticipated discrimination and non-affirmation were associated with decreased access to healthcare. Among TW living with HIV, higher levels of anticipated discrimination, non-affirmation, and social support were associated with decreased healthcare access. Among TW living without HIV in the site-based mode, resilience was positively associated with positive healthcare experiences and inversely associated with barriers to healthcare access. Among TW living without HIV in the online mode, anticipated discrimination was associated with barriers to healthcare access; resilience was positively associated with positive healthcare experiences and inversely associated with barriers to healthcare access. Conclusions: Gender minority stress was associated with increased barriers to healthcare access among TW in the US, regardless of HIV status. Resilience factors did not mediate this effect. Interventions aiming to increase healthcare access among TW can be aided by efforts to mitigate drivers of gender minority stress and improve patient experiences in healthcare facilities.

Background: Despite increases in the lifetime prevalence of anal intercourse, little is known about the safety of inflatable penile prosthesis use during anal intercourse or the forces required for anal penetration. Aim: We sought to determine the force required for anal penetration. Methods: A digital force gauge device was secured to a silicone phallus with a length and girth representative of the average male phallus in the United States and inserted into the anal canal of 6 male participants for a total of 5 measurements per participant. The maximum axial forces on insertion were recorded. Participants then completed a survey eliciting demographic information and past experience with receptive anal intercourse. Outcomes: The outcome measure was the force recorded during insertion of a force gauge device into the anal canal. Results: The median maximal force recorded on anal penetration was 26.5 N (2.7 kg; range: 16.1-51.7 N or 1.64-5.27 kg). Participants who engaged in receptive anal intercourse more than once per month tended to use lesser median maximal forces (25.7 N or 2.62 kg) than participants who engaged less frequently in receptive anal intercourse (41.6 N or 4.24 kg). Clinical Implications: Compared with the forces required for vaginal penetration, anal penetration forces may cause additional mechanical stress to the phallus. Strengths and Limitations: While the study is limited primarily in its small sample size and in the use of a single device for anal penetration with a set size and rigidity, the resulting findings presented here are to our knowledge the first reported data pertaining the force required for anal penetration. Conclusion: As the forces required for anal penetration exceeded those for vaginal penetration, clinicians may need to carefully counsel patients on the safe use of an inflatable penile prosthesis for anal intercourse.

We conducted a survey of US urologic oncologists to assess provider practice patterns regarding female reproductive organ-sparing (ROS) and nerve-sparing radical cystectomy (RC) in pre- and postmenopausal patients with organ-confined disease. We identified significant gaps in adoption of female ROS and nerve-sparing techniques. Future efforts should increase training and education in this area among urologists to optimize female RC outcomes. Background: Female reproductive organ-sparing (ROS) and nerve-sparing radical cystectomy (RC) techniques have been shown to be oncologically safe and to improve sexual function outcomes among select patients with organconfined disease. We sought to characterize practice patterns regarding female ROS and nerve-sparing RC among US urologists. Patients and Methods: We conducted a cross-sectional survey of members of the Society of Urologic Oncology to assess provider-reported frequency of ROS and nerve-sparing RC in premenopausal and postmenopausal patients with non-muscle-invasive bladder cancer that failed intravesical therapy or clinically localized muscle-invasive bladder cancer. Results: Among 101 urologists, 80 (79.2%) reported that they routinely resect the uterus/cervix, 68 (67.3%) the neurovascular bundle, 49 (48.5%) the ovaries, and 19 (18.8%) a portion of the vagina when performing RC in premenopausal patients with organ-confined disease. When asked about changes to approach in postmenopausal patients, 71 participants (70.3%) reported that they were less likely to spare the uterus/cervix, 44 (43.6%) were less likely to spare the neurovascular bundle, 70 (69.3%) were less likely to spare the ovaries, and 23 (22.8%) were less likely to spare a portion of the vagina. Conclusion: We identified significant gaps in adoption of female ROS and nerve-sparing RC techniques for patients with organ-confined disease, despite evidence that ROS and nerve-sparing techniques are oncologically safe and can optimize functional outcomes in select patients. Future efforts should improve provider training in and education about ROS and nerve-sparing RC to improve postoperative outcomes among female patients. [ABSTRACT FROM AUTHOR]

Background: The COVID-19 pandemic was accompanied by an "infodemic"–an overwhelming excess of accurate, inaccurate, and uncertain information. The social media-based science communication campaign Dear Pandemic was established to address the COVID-19 infodemic, in part by soliciting submissions from readers to an online question box. Our study characterized the information needs of Dear Pandemic's readers by identifying themes and longitudinal trends among question box submissions. Methods: We conducted a retrospective analysis of questions submitted from August 24, 2020, to August 24, 2021. We used Latent Dirichlet Allocation topic modeling to identify 25 topics among the submissions, then used thematic analysis to interpret the topics based on their top words and submissions. We used t-Distributed Stochastic Neighbor Embedding to visualize the relationship between topics, and we used generalized additive models to describe trends in topic prevalence over time. Results: We analyzed 3839 submissions, 90% from United States-based readers. We classified the 25 topics into 6 overarching themes: 'Scientific and Medical Basis of COVID-19,' 'COVID-19 Vaccine,' 'COVID-19 Mitigation Strategies,' 'Society and Institutions,' 'Family and Personal Relationships,' and 'Navigating the COVID-19 Infodemic.' Trends in topics about viral variants, vaccination, COVID-19 mitigation strategies, and children aligned with the news cycle and reflected the anticipation of future events. Over time, vaccine-related submissions became increasingly related to those surrounding social interaction. Conclusions: Question box submissions represented distinct themes that varied in prominence over time. Dear Pandemic's readers sought information that would not only clarify novel scientific concepts, but would also be timely and practical to their personal lives. Our question box format and topic modeling approach offers science communicators a robust methodology for tracking, understanding, and responding to the information needs of online audiences.

Vaccine hesitancy remains an issue in the United States. This study conducted an online survey [N = 3,013] using the Social Science Research Solution [SSRS] Opinion Panel web panelists, representative of U.S. adults age 18 and older who use the internet, with an oversample of rural-dwelling and minority populations between April 8 and April 22, 2021- as vaccine eligibility opened to the country. We examined the relationship between COVID-19 exposure and socio-demographics with vaccine intentions [eager-to-take, wait-and-see, undecided, refuse] among the unvaccinated using multinomial logistic regressions [ref: fully/partially vaccinated]. Results showed vaccine intentions varied by demographic characteristics and COVID-19 experience during the period that eligibility for the vaccine was extended to all adults. At the time of the survey approximately 40% of respondents were unvaccinated; 41% knew someone who had died of COVID-19, and 38% had experienced financial hardship as a result of the pandemic. The vaccinated were more likely to be highly educated, older adults, consistent with the United States initial eligibility criteria. Political affiliation and financial hardship experienced during the pandemic were the two most salient factors associated with being undecided or unwilling to take the vaccine.

Classroom teachers in the United States are absent on average approximately 6 percent of a school year. Despite the prevalence of teacher absences, surprisingly little research has assessed the key source of replacement instruction: substitute teachers. Using detailed administrative and survey data from a large urban school district, we document the prevalence, predictors, and distribution of substitute coverage across schools. Less advantaged schools systematically exhibit lower rates of substitute coverage compared with peer institutions. Observed school, teacher, and absence characteristics account for only part of this school variation. In contrast, substitute teachers' preferences for specific schools, mainly driven by student behavior and support from teachers and school administrators, explain a sizable share of the unequal distribution of coverage rates above and beyond standard measures in administrative data.

White‐nose syndrome (WNS) has caused dramatic declines of several cave‐hibernating bat species in North America since 2006, which has increased the activity of non‐susceptible species in some geographic areas or during times of night formerly occupied by susceptible species—indicative of disease‐mediated competitive release (DMCR). Yet, this pattern has not been evaluated across multiple bat assemblages simultaneously or across multiple years since WNS onset. We evaluated whether WNS altered spatial and temporal niche partitioning in bat assemblages at four locations in the eastern United States using long‐term datasets of bat acoustic activity collected before and after WNS arrival. Activity of WNS‐susceptible bat species decreased by 79–98% from pre‐WNS levels across the four study locations, but only one of our four study sites provided strong evidence supporting the DMCR hypothesis in bats post‐WNS. These results suggest that DMCR is likely dependent on the relative difference in activity by susceptible and non‐susceptible species groups pre‐WNS and the relative decline of susceptible species post‐WNS allowing for competitive release, as well as the amount of time that had elapsed post‐WNS. Our findings challenge the generality of WNS‐mediated competitive release between susceptible and non‐susceptible species and further highlight declining activity of some non‐susceptible species, especially Lasiurus borealis, across three of four locations in the eastern United States. These results underscore the broader need for conservation efforts to address the multiple potential interacting drivers of bat declines on both WNS‐susceptible and non‐susceptible species.

Objective: To evaluate differences in perioperative clinical outcomes in men undergoing artificial urinary sphincter (AUS) implantation in primary versus replacement settings. Secondarily, we aimed to identify patient-related factors contributing to complications associated with AUS placement. Materials and Methods: A review of the American College of Surgeons-National Surgical Quality Improvement Program was performed between 2010 and 2018 identifying males undergoing AUS implantation. Subjects were further subdivided into primary implantation or removal/replacement of AUS simultaneously via current procedural terminology codes 53445 and 53447, respectively. 30-Day postoperative outcomes were compared between cohorts using t-test and Fisher's exact test. The relationship between patient factors and complications was evaluated using logistic regression. Results: A total of 1,892 patients were identified: 1,445 primary AUS placement and 447 AUS replacement procedures. Patients undergoing AUS replacement were statistically older than those undergoing primary implantation (71.4 vs 69.7 years, P < .001). AUS replacement procedures were associated with an increased rate of superficial surgical site infection (SSI) compared to primary procedures (1.3% vs 0.4%, P = .042). There were no differences identified between cohorts for deep SSI, cardiopulmonary complications, reoperation, operative time, or length of stay. Logistic regression demonstrated that higher body mass index was found to be independent risk factors for any complications, and diabetes mellitus was associated with increased risk of AUS-related readmission. Conclusion: Within the perioperative period, patients undergoing replacement AUS have an increased risk of superficial SSI compared to primary AUS implantation. These findings can assist with appropriate perioperative counseling of patients undergoing primary and replacement AUS implantations. [ABSTRACT FROM AUTHOR]

On average, secondary school students in the United States are absent from school three weeks per year. For this study, we are able to link middle and high school teachers to the class-attendance of students in their classrooms and create measures of teachers' contributions to student class-attendance. We find systematic variation in teacher effectiveness at reducing unexcused class absences. These differences across teachers are as stable as those for student achievement, but teacher effectiveness on attendance only weakly correlates with their effects on achievement. A high value-added to attendance teacher has a stronger impact on students' likelihood of finishing high school than does a high value-added to achievement teacher. Moreover, high value-added to attendance teachers can motivate students to pursue higher academic goals. These positive effects are particularly salient for low-achieving and low-attendance students.

Scant attention has been paid to intersecting vulnerabilities experienced by Black, Latinx, and older adults of color (BLOAC) that increase COVID-19 related risks. Structural inequities have resulted in disproportionate rates of chronic conditions and limited access to care. Media coverage, focused on COVID-19 mortality among institutionalized older adults (OA), has overlooked community-dwelling OA, leaving their unique risks unaddressed in research and intervention efforts. Key vulnerabilities impacting noninstitutionalized BLOAC exacerbating adverse health outcomes during COVID-19 are discussed, and recommendations are given for gerontological social work (GSW) education, training, and practice to meet the needs of BLOAC during the COVID-19 pandemic.

Emerging disease threats are on the rise. Risk communication in an emerging threat is used by public health officials to reach the population in a timely and effective manner. However, limited research has drawn on data gathered during an emerging threat to understand how risk communication shapes intervention perceptions. This analysis examines the relationship between risk communication, especially where information comes from, and receptivity to individual-level and community-level health interventions in an emerging threat using evidence from the 2016 rise of Zika. Data comes from a repeat cross-sectional survey conducted three times in 2016, representative of the United States population. Drawing on leading theories of risk communication, a structural model (SEM) is used to measure the relationships of interest. Two distinct SEMs are used to compare and contrast the relationship between source of information and individual health behavior change and community-level health interventions while also exploring the role of knowledge, perceived risk, and demographics. Results of both direct and indirect SEM pathways show different sources of information may be more effective in promoting particular interventions. Promoting community-level interventions can be accomplished through dissemination of information in print news to increase knowledge and ultimately receptivity. However, there is a far more complex relationship between risk communication and personal intervention receptivity. With a more nuanced understanding of the way information from a particular source effects intervention receptivity, communicators can reach the public more effectively to limit the consequences of an emerging public health threat.

Objective: To provide the first comprehensive analysis of the Twitterverse amongst academic urologists and programmes in North America. Methods: Using national accreditation and individual programme websites, all active urology residency programmes (USA and Canada) and academic Urology faculty at these programmes were identified. Demographic data for each programme American Urological Association [AUA] section, resident class size) and physician (title, fellowship training, Scopus Hirsch index [H‐index] and citations) were documented. Twitter metrics (Twitter handle, date joined, # tweets, # followers, # following, likes) for programmes and physicians were catalogued (data capture: March–April 2019). Descriptive analyses and temporal trends in Twitter utilisation amongst programmes and physicians were assessed. Multivariable logistic regression was used to identify predictors of Twitter use. Results: In all, 156 academic programmes (143 USA, 13 Canada) and 2214 academic faculty (2015 USA, 199 Canada) were identified. Twitter utilisation is currently 49.3% and 34.1% amongst programmes and physicians, respectively, and continues to increase. On multivariable analysis, programmes with 3–5 residents/year and programmes with a higher percentage of faculty Twitter engagement were more likely to have Twitter accounts. From a physician perspective, those with fellowship training, lower academic rank (Clinical Instructor, Assistant Professor, Associate Professor vs Professor) and higher H‐indices were more likely to have individual Twitter accounts. Conclusion: There is a steady increase in Twitter engagement amongst Urology programmes and academic physicians. Faculty Twitter utilisation is an important driver of programme Twitter engagement. Twitter social media activity is strongly associated with academic productivity, and may in fact drive academic metrics. Within Urology, social media presence appears to be proportional to academic activity. [ABSTRACT FROM AUTHOR]

Perceptions of infectious diseases are important predictors of whether people engage in disease‐specific preventive behaviors. Having accurate beliefs about a given infectious disease has been found to be a necessary condition for engaging in appropriate preventive behaviors during an infectious disease outbreak, while endorsing conspiracy beliefs can inhibit preventive behaviors. Despite their seemingly opposing natures, knowledge and conspiracy beliefs may share some of the same psychological motivations, including a relationship with perceived risk and self‐efficacy (i.e., control). The 2015–2016 Zika epidemic provided an opportunity to explore this. The current research provides some exploratory tests of this topic derived from two studies with similar measures, but different primary outcomes: one study that included knowledge of Zika as a key outcome and one that included conspiracy beliefs about Zika as a key outcome. Both studies involved cross‐sectional data collections that occurred during the same two periods of the Zika outbreak: one data collection prior to the first cases of local Zika transmission in the United States (March–May 2016) and one just after the first cases of local transmission (July–August). Using ordinal logistic and linear regression analyses of data from two time points in both studies, the authors show an increase in relationship strength between greater perceived risk and self‐efficacy with both increased knowledge and increased conspiracy beliefs after local Zika transmission in the United States. Although these results highlight that similar psychological motivations may lead to Zika knowledge and conspiracy beliefs, there was a divergence in demographic association. [ABSTRACT FROM AUTHOR]

The purpose of this article is to explain the strategies used in the "Set‐up" phase of developing computer‐based education on the care and management of incarcerated people who are older and/or dying. Public health nurses have an opportunity to support efforts in educating corrections staff to enhance health care for older and dying inmates. Such endeavors can promote social justice through inmates receiving evidence‐based care that parallels that received by the community at large. "Set‐up" is the first of four phases in the Institute for Healthcare Improvement's Framework for Going to Full Scale. Our design approach was threefold and included an environmental scan, a modified Delphi survey, and a usability study. An expert advisory board was consulted throughout the Set‐up Phase. Participants for the Delphi Survey had expertise in geriatrics and corrections health care. Usability testing was conducted at two State Correctional Institutions. The Delphi Survey consisted of three Qualtrics surveys. Usability testing examined navigability; detected problems; observed time spent solving problems; identified problem severity; and developed recovery strategies. The Set‐up established proof of concept, three prototype modules, and a specifications document to guide future programming. In addition, a Technology Niche Analyses® provided a preliminary commercialization plan (NIH, 2017). The Set‐up phase has been instrumental in exposing the available infrastructure for dissemination of an educational product within corrections and may be a first step in addressing public health concerns on issues in aging. Commercial feasibility of the program and the need for continued research for Developing the Scalable Unit were established. [ABSTRACT FROM AUTHOR]

Limiting the spread and impact of Zika was a major global priority in 2016, which required a variety of vector control measures. The success of vector control campaigns is varied and often dependent on public or political will. This paper examines the change over time in the United States population's support for vector control and the factors that predicted support for three vector control strategies (i.e., indoor spraying, outdoor spraying, and use of larvacide tablets) during the 2016 Zika outbreak in the United States. Data is from a nationally representative random digit dial sample conducted at three time points in 2016. Bivariate and multivariate regression analyses were used, treating data as a pooled cross-sectional sample. Results show public support for vector control strategies depends on both perceived risk for disease and knowledge of disease characteristics, as well is confidence in government to prevent the threat. Support varied based on vector control method: indoor spraying, aerial spraying, and use of larvacide tables. Results can aide public health officials in implementing effective vector control campaigns depending on the vector control strategy of choice. Results have implications for ways to design effective prevention campaigns in future emerging infectious disease threats. [ABSTRACT FROM AUTHOR]

We used latent class analysis to examine Zika virus-related information-accessing behavior of US residents during the 2016 international outbreak. We characterized 3 classes of information-accessing behavior patterns: universalists, media seekers, and passive recipients. Understanding these patterns is crucial to planning risk communication during an emerging health threat. [ABSTRACT FROM AUTHOR]

Children at the highest risk for not being ready for school live in poverty and/or with chronic health conditions. High-quality early childhood education (ECE) programs can be used to help kids be ready for school; however, the United States lacks a comprehensive ECE system, with only half of 3- and 4-year-olds being enrolled in preschool, lagging behind 28 high-income countries. As addressing social determinants of health gains prominence in pediatric training and practice, there is increasing interest in addressing ECE disparities. Unfortunately, evidence is lacking for clinically based, early educational interventions. New interventions are being developed asynchronously in pediatrics and education, often without knowledge of the evidence base in the other's literature. In this State-of-the-Art Review, we synthesize the relevant work from the field of education (searchable through the Education Resources Information Center, also known as the "PubMed" of education), combining it with relevant literature in PubMed, to align the fields of pediatrics and education to promote this timely transdisciplinary work. First, we review the education literature to understand the current US achievement gap. Next, we provide an update on the impact of child health on school readiness and explore emerging solutions in education and pediatrics. Finally, we discuss next steps for future transdisciplinary work between the fields of education and pediatrics to improve the health and school readiness of young children. [ABSTRACT FROM AUTHOR]

Background: As the incidence of Zika infection accelerated in Central and South American countries from November 2015 through April 2016, U.S. public health officials developed vector control and risk communication strategies to address mosquito-borne and sexual modes of transmission. This study reports upon U.S. perceptions of the Zika virus prior to domestic transmission, and analyzes the association of socio-economic, political, knowledge and risk factors with population receptivity to selected behavioral, environmental, and clinical intervention strategies. Methods: A representative sample of 1,233 U.S. residents was drawn from address-based telephone and mobile phone lists, including an oversample of 208 women of child-bearing age living in five U.S. southern states. Data were collected between April and June, 2016, and weighted to represent U.S. population distributions. Results: Overall, 78% of the U.S. population was aware of Zika prior to domestic transmission. Those unaware of the novel virus were more likely to be younger, lower income, and of Hispanic ethnicity. Among those aware of Zika, over half would delay pregnancy for a year or more in response to public health warnings; approximately one third agreed with a possible vector-control strategy of targeted indoor spraying by the government; and nearly two-thirds agreed that the government should make pregnancy-termination services available to women who learn their fetus had a Zika-related birth defect. Receptivity to these public health interventions varied by age, risk perception, and knowledge of the virus. Conclusion: Risk salience and population receptivity to public health interventions targeting a novel virus can be conditioned on pre-existing characteristics in the event of an emerging infectious disease. Risk communicators should consider targeted strategies to encourage adoption of behavioral, environmental, and clinical interventions. [ABSTRACT FROM AUTHOR]

Online college courses are a rapidly expanding feature of higher education, yet little research identifies their effects relative to traditional in-person classes. Using an instrumental variables approach, we find that taking a course online, instead of in-person, reduces student success and progress in college. Grades are lower both for the course taken online and in future courses. Students are less likely to remain enrolled at the university. These estimates are local average treatment effects for students with access to both online and in-person options; for other students, online classes may be the only option for accessing college-level courses.

Keystone virus, a California-serogroup orthobunyavirus, was first isolated in 1964 from mosquitoes in Keystone, Florida. There were no prior reports of isolation from humans, despite studies suggesting that ~20% of persons living in the region are seropositive. We report virus isolation from a Florida teenager with a rash and fever. [ABSTRACT FROM AUTHOR]

Abstract: The first US-Japan meeting on “error-prone DNA synthesis” convened at the Maui Prince Hotel, from December 20 through December 21, 2004. In keeping with the traditions of US-Japan conferences, the meeting was small and intimate, and comprised of 22 participants: 11 from Japan, 10 from the United States, and one from Israel. The program featured platform presentations from each of the participants, with considerable time for discussion of topics related to each of the themes of the meeting. The following pages present an introduction to the unanswered questions on error-prone DNA synthesis. These questions were the dominant themes that permeated the extensive discussions. Edited abstracts of each of the presentations, organized into primary topic themes, are presented. [Copyright &y& Elsevier]
