Immunization with an mRNA DTP vaccine protects against pertussis in rats.

Bordetella pertussis is a Gram-negative bacterium that is the causative agent of the respiratory disease known as pertussis. Since the switch to the acellular vaccines of DTaP and Tap, pertussis cases in the US have risen and cyclically fallen. We have observed that mRNA pertussis vaccines are immunogenic and protective in mice. Here, we further evaluated the pertussis toxoid mRNA antigen and refined the formulation based on optimal pertussis toxin neutralization in vivo. We next evaluated the mRNA pertussis vaccine in Sprague-Dawley rats using an aerosol B. pertussis challenge model paired with whole-body plethysmography to monitor coughing and respiratory function. Female Sprague-Dawley rats were primed and boosted with either commercially available vaccines (DTaP or wP-DTP), an mRNA-DTP vaccine, or mock-vaccinated. The mRNA-DTP vaccine was immunogenic in rats and induced antigen-specific IgG antibodies comparable to DTaP. Rats were then aerosol challenged with a streptomycin-resistant emerging clinical isolate D420Sm1. Bacterial burden was assessed at days 1 and 9 post-challenge, and the mRNA vaccine reduced burden equal to both DTaP and wP-DTP. Whole-body plethysmography revealed that mRNA-DTP vaccinated rats were well protected against coughing which was comparable to the non-challenged group. These data suggest that an mRNA-DTP vaccine is immunogenic in rats and provides protection against aerosolized B. pertussis challenge in Sprague-Dawley rats.

Effects of respiratory isolation for tuberculosis to reduce community-based transmission: a systematic review.

BACKGROUND: Respiratory isolation of people with pulmonary tuberculosis (TB), including after treatment initiation, is used to prevent community-based transmission; yet guidelines on duration are limited and implementation is heterogeneous. This systematic review synthesized evidence on respiratory isolation for TB to inform National TB Coalition of America guidelines. METHODS: After searching six databases, eight reviewers screened and extracted data in duplicate on effects of respiratory isolation compared to no isolation or masking. Studies were stratified by outcomes: TB infection or disease in contacts, mortality, hospitalization duration, patient and health system costs, and impact on mental health or stigma. We used a convergent integrated approach to synthesize quantitative and qualitative findings and assess limitations. RESULTS: Seventeen studies were included. There were limited data directly comparing isolation to non-isolation interventions, including effects after treatment initiation. One randomized controlled trial suggested treatment in a sanatorium versus at home did not affect TB incidence in contacts. Modelling studies suggest isolation may reduce transmission, but relied on various assumptions, and isolation was implemented alongside other interventions. Descriptive, mixed-methods, and qualitative studies described adverse impacts of isolation on employment, education, food/housing security, and mental health due to transmission fears, stigma and social isolation. Impacts were compounded in marginalized groups including indigenous and incarcerated persons. CONCLUSION: Data to support current isolation practices, particularly after effective treatment initiation, to reduce TB transmission in communities are limited. Public health guidance should weigh the negative impacts on people with TB against decreased community transmission to make evidence-based decisions about respiratory isolation.

Polymyxins retain in vitro activity and in vivo efficacy against "resistant" Acinetobacter baumannii strains when tested in physiological conditions.

The emergence of plasmid-mediated resistance threatens the efficacy of polymyxins as the last line of defense against pan-drug-resistant infections. However, we have found that using Mueller-Hinton II (MHII), the standard minimum inhibitory concentration (MIC) medium, results in MIC data that are disconnected from in vivo treatment outcomes. We found that culturing putative colistin-resistant Acinetobacter baumannii clinical isolates, as defined by MICs of >2 mg/L in standard MHII testing conditions, in bicarbonate-containing media reduced MICs to the susceptible range by preventing colistin resistance-conferring lipopolysaccharide modifications from occurring. Furthermore, the lower MICs in bicarbonate-containing media accurately predicted in vivo efficacy of a human-simulated dosing strategy of colistin and polymyxin B in a lethal murine infection model for some polymyxin-resistant A. baumannii strains. Thus, current polymyxin susceptibility testing methods overestimate the contribution of polymyxin resistance-conferring mutations and incorrectly predict antibiotic activity in vivo. Polymyxins may remain a viable therapeutic option against Acinetobacter baumannii strains heretofore determined to be "pan-resistant."

The association between food insecurity and colorectal cancer screening: 2018-2021 New York State Behavioral Risk Factor Surveillance System (BRFSS).

PURPOSE: To assess the association between food insecurity and colorectal cancer screening uptake in screening eligible participants in New York State. METHODS: We analyzed 28,154 adults who participated in New York State Behavioral Risk Factor Surveillance System (BRFSS) from 2018 to 2021, were age-eligible for colorectal cancer screening based on the USPSTF guidelines at the time of survey administration and answered a version of the administered survey that included the module on food insecurity. Participants were defined as food insecure if they self-reported being always, usually, or sometimes stressed about having enough money to buy nutritious meals in the past 12 months. We compared demographic, healthcare access, overall health status, food insecurity by colorectal cancer screening status. Multivariable analyses were performed to assess the association of food insecurity and colorectal cancer screening status after adjusting for relevant covariates. Weighted analyses were performed using survey procedures to obtain population estimates. RESULTS: Food insecurity was statistically significantly associated a decreased likelihood of being up to date on colorectal cancer screening (ORadj 0.83, 95% CI [0.72, 0.94]) and being ever screened for colorectal cancer (ORadj 0.74, 95% CI [0.64, 0.87]) after adjusting for overall health status, healthcare coverage, interview year, age, race/ethnicity, sex, educational attainment, and income. Health status, health coverage, age, and Non-Hispanic Black race/ethnicity showed positive, statistically significant association with ever being screened and with being up to date for colorectal cancer screening. Lower income, lower educational attainment, and non-Hispanic Asian race/ethnicity were statistically significant inverse predictors of ever being screened and being up to date on screening. CONCLUSION: This project assessed the association between food insecurity and colorectal cancer screening uptake using the BRFSS survey. Food insecurity may be an important predictor for colorectal cancer screening uptake in eligible adults in the United States. The results from the study can inform future interventions and policies designed to improve participation in routine colorectal cancer screening.

The Risk of Sympathetic Ophthalmia Associated with Open-Globe Injury Management Strategies: A Meta-analysis.

TOPIC: Sympathetic ophthalmia (SO) is a sight-threatening granulomatous panuveitis caused by a sensitizing event. Primary enucleation or primary evisceration, versus primary repair, as a risk management strategy after open-globe injury (OGI) remains controversial. CLINICAL RELEVANCE: This systematic review was conducted to report the incidence of SO after primary repair compared with that of after primary enucleation or primary evisceration. This enabled the reporting of an estimated number needed to treat. METHODS: Five journal databases were searched. This review was registered with International Prospective Register of Systematic Reviews (identifier, CRD42021262616). Searches were carried out on June 29, 2021, and were updated on December 10, 2022. Prospective or retrospective studies that reported outcomes (including SO or lack of SO) in a patient population who underwent either primary repair and primary enucleation or primary evisceration were included. A systematic review and meta-analysis were carried out in accordance with Preferred Reporting Items for Systematic Reviews and Meta-analyses guidelines. Random effects modelling was used to estimate pooled SO rates and absolute risk reduction (ARR). RESULTS: Eight studies reporting SO as an outcome were included in total. The included studies contained 7500 patients and 7635 OGIs. In total, 7620 OGIs met the criteria for inclusion in this analysis; SO developed in 21 patients with OGI. When all included studies were pooled, the estimated SO rate was 0.12% (95% confidence interval [CI], 0.00%-0.25%) after OGI. Of 779 patients who underwent primary enucleation or primary evisceration, no SO cases were reported, resulting in a pooled SO estimate of 0.05% (95% CI, 0.00%-0.21%). For primary repair, the pooled estimate of SO rate was 0.15% (95% CI, 0.00%-0.33%). The ARR using a random effects model was -0.0010 (in favour of eye removal; 95% CI, -0.0031 [in favor of eye removal] to 0.0011 [in favor of primary repair]). Grading of Recommendations, Assessment, Development, and Evaluations analysis highlighted a low certainty of evidence because the included studies were observational, and a risk of bias resulted from missing data. DISCUSSION: Based on the available data, no evidence exists that primary enucleation or primary evisceration reduce the risk of secondary SO.

Financial conflicts of interest among presenters, panellists and moderators at haematology and oncology FDA workshops.

OBJECTIVE: To assess the characteristics and financial conflicts of interest of presenters, panellists and moderators at haematology and oncology workshops held jointly with or hosted by the US FDA. SETTING: We included information on all publicly available haematology or oncology FDA workshop agendas held between 1 January 2018 and 31 December 2022. EXPOSURE: General and research payments reported on Open Payments, industry funding to patient advocacy organizations reported on their webpages or 990 tax forms and employment in both pharmaceutical and regulatory settings. RESULTS: Among physicians eligible for payments, 78% received at least one payment from the industry between 2017 and 2021. The mean general payment amount was $82,170 for all years ($16,434 per year) and the median was $14,906 for all years ($2981 per year). Sixty-nine per cent of patient advocacy speakers were representing organizations that received financial support from the pharmaceutical industry. Among those representing regulatory agencies or pharmaceutical companies, 16% had worked in both settings during their careers. CONCLUSIONS AND RELEVANCE: Our findings in this cross-sectional study show a majority of US-based physician presenters at haematology and oncology workshops held jointly with members of the US FDA have some financial conflict of interest with the pharmaceutical industry. These findings support the need for clear disclosures and suggest that a more balanced selection of presenters with fewer conflicts may help to limit bias in discussions between multiple stakeholders.

An Online Mindfulness-Based Group Intervention for Tics: A Pilot Randomized Controlled Trial.

BACKGROUND: Current treatments for Tourette syndrome (TS) and persistent tic disorder (PTD) are often insufficiently effective, inaccessible, and frequently associated with adverse events. Thus, we must continue to develop and test effective, accessible, and safe treatment options. OBJECTIVE: We aimed to conduct a pilot randomized controlled trial (RCT) comparing a novel, videoconference-delivered group mindfulness-based intervention for tics (MBIT) to videoconference-delivered group psychoeducation, relaxation, and supportive therapy (PRST) for adults with TS or PTD. METHODS: Thirty-two adults with TS or PTD were randomly assigned to receive 8 weeks of either MBIT or PRST. Tic severity, tic-related impairment, and global improvement were assessed by a trained, independent evaluator who was masked to treatment condition at baseline (week 0), posttreatment (week 9), 1-month follow-up, and 6-month follow-up. All study procedures were conducted online via secure videoconferencing. RESULTS: Twenty-eight participants began treatment and were included in analyses. MBIT, relative to PRST, was associated with a significantly greater decline in tic severity (d = 0.85) and tic-related impairment (d = 0.99) from baseline to posttreatment. Treatment response was significantly higher in MBIT (69%) than in PRST (13%). Neither treatment resulted in serious adverse effects. The durability of treatment outcomes is also reported and discussed. CONCLUSIONS: The results from this pilot RCT suggest that videoconference-delivered group MBIT may be an efficacious, accessible, and safe intervention for adults with tics. Future research is necessary to confirm these preliminary findings. © 2024 The Author(s).

Attention-deficit/hyperactivity disorder and the menstrual cycle: Theory and evidence.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder that exhibits striking sex differences in symptoms, prevalence, and associated problems across development. Etiological factors and mechanisms underlying these sex differences remain one of the most understudied aspects of this disorder. The current paper seeks to provide a novel theoretical framework for understanding this phenomenon by reviewing evidence that females with ADHD may experience a "double whammy" of organizational and activational pubertal hormonal effects. We propose a novel theory of activational effects of cyclical circulating ovarian hormones on ADHD with increasing risk at times of rapid declines in estrogen. These declines may decrease executive function and trait control at two points of the cycle characterized by biphasic affective risk: (1) increases in approach/risk-taking behaviors at mid-cycle (periovulatory) and (2) increases in avoidance/negative affect perimenstrually. Low estrogen and control may then interact with increases in positive and negative affect, respectively, to increase hyperactivity-impulsivity symptoms post-ovulation and inattention symptoms perimenstrually. These interactions may be exacerbated by organizational pubertal effects on relatively overdeveloped limbic circuitry and adolescent-specific social pressures magnified in females with ADHD.

Reporting of asthma mobile health data for clinical practice: a qualitative study of pediatric provider perspectives.

OBJECTIVE: Mobile health (mHealth), defined as the use of mobile phones or applications in healthcare, has been developed to enhance asthma care; yet implementation is inconsistent, and few studies have focused on provider perspectives on use in daily practice. The purpose of this study was to explore primary care pediatric provider perspectives regarding mHealth use in clinical practice for children with asthma. METHODS: A qualitative, descriptive approach was utilized to perform semi-structured interviews on asthma mHealth use with providers caring for children with asthma. Interview transcripts were coded by two independent investigators and any differences were reconciled. Interviews continued until thematic saturation was achieved. RESULTS AND CONCLUSIONS: Seventeen pediatric providers were recruited and interviewed. Three themes identified included implementation benefits, implementation barriers, and reporting desires, with 11 subthemes. Many subthemes were consistent across providers (e.g. self-management benefits and electronic medical record integration), while others such as provider clinical burden and approach to integrating mHealth data reports into daily workflow demonstrated variability. Provider perspectives highlight the potential of mHealth applications in asthma self-management while offering challenges related to clinical burden and suggestions for reporting and workflow integration. These results provide valuable perspectives on mHealth use and reporting to ensure provider efficiency and technology-enhanced asthma care. This study investigates pediatric provider perspectives on asthma mobile health use and reporting in daily practice, a topic that has not sufficiently been explored within the literature. Results can guide best practices, encourage more consistent use, and maximize the benefits of asthma mHealth tools by providers.

A multi-informant qualitative analysis of desired features for an mHealth tool for youth living with HIV in South Carolina.

OBJECTIVE: Youth living with HIV (YLHIV) in the southern United States experience poor outcomes across the HIV care continuum and are at high-risk for virologic failure. This study used a qualitative, community-engaged approach to inform the development of a tailored mobile Health (mHealth) tool for YLHIV in South Carolina (SC). METHODS: Semistructured qualitative interviews were conducted with YLHIV in SC (n = 16) and their HIV care providers (n = 15). Focus group discussions (FGDs) were also conducted with HIV-focused community-based organization staff (n = 23). Interviews and FGDs queried desired components for a future mHealth tool tailored for YLHIV. Data were analyzed using a team-based rapid qualitative approach. RESULTS: Across informants, key themes emerged related to medical management of HIV, including a desire for connections with medical providers, appointment and medication reminders, and accurate HIV information. In addition, informants voiced a desire for mental health resources to be integrated into the app. Connection with HIV-positive peers also emerged as a key desire from youth informants. In terms of app design, informants emphasized the need for strict privacy practices, a youth-friendly design, compensation for use, and integration with existing healthcare systems. CONCLUSIONS: mHealth interventions developed for YLHIV should meet the mental health and social needs of YLHIV in addition to their medical needs. In addition, the highly stigmatized nature of HIV requires careful consideration when designing digital tools-youth want their privacy prioritized, but also express strong desire for social support to help cope with the isolation and stigma of this chronic health condition.

A Qualitative Study of Transportation-Related Barriers to HIV Care in South Carolina.

OBJECTIVES: Addressing structural barriers to care for people living with human immunodeficiency virus (HIV) in the southern United States is critical to increase rates of viral suppression and to reduce existing HIV disparities. This qualitative study aimed to describe transportation-related barriers experienced by people living with HIV in South Carolina, understand perceived effects of transportation vulnerability on HIV care, and explore strategies used by individuals to overcome transportation-related challenges. METHODS: We conducted semistructured interviews with 20 people living with HIV from South Carolina who were either reengaging in HIV care after a prolonged absence (>9 months) or in care but with a detectable viral load (ie, >200 copies/mL). All people living with HIV reported transportation vulnerability. A deductive/inductive approach was used to identify transportation-related barriers perceived to negatively affect HIV care. We also identified strategies and resources described by people living with HIV as helpful in addressing transportation challenges. RESULTS: Participants described a range of transportation-related barriers to HIV care, including lack of access to reliable, safe, and affordable transportation, as well as stigma due to HIV and socioeconomic statuses. These barriers were reported to negatively affect engagement in care and worsen both physical and mental health. Participants indicated flexible clinic policies and instrumental support from family and friends were useful in overcoming barriers. CONCLUSIONS: This study offers insight for the development of transportation interventions to improve equitable access to HIV care for people living with HIV in South Carolina. It also calls attention to the ways in which transportation vulnerability, HIV-related stigma, and disability status intersect to create unique challenges for some people living with HIV.

The Management of Pediatric Asthma Using Telehealth: An Integrative Review.

Introduction: Asthma is one of the most chronic noncommunicable diseases of childhood, affecting 1 in 12 children in the United States. The use of telemedicine for the management of pediatric asthma has shown improved health outcomes; however, it is important to understand what can impact its acceptance. The purpose of this review was to identify the facilitators and barriers to pediatric asthma management, as viewed by stakeholders. Methods: An electronic literature search was performed using PubMed, Scopus, and Cumulative Index to Nursing and Allied Health Literature Complete. Articles included in the review contained perceptions of the use of telemedicine for the management of pediatric asthma, as viewed by stakeholders. The socioecological model was used as the theoretical framework to extract data based on its five levels. Results: After reviewing full texts of 143 articles, 118 were excluded, leaving 25 articles included in this review. A majority of included articles focused on mobile health (m-Health) studies for the management of pediatric asthma, with the remaining articles studying synchronous telemedicine or a combination of modalities. Common themes were identified; however, most were focused on the use of m-Health and few studies contained the viewpoints of the caregiver, children, or providers regarding synchronous telemedicine. Discussion: This integrative review identified a number of facilitators and barriers for the management of asthma using telemedicine. However, more qualitative studies are needed to evaluate the perceptions of caregivers, patients, and primary providers regarding synchronous telehealth. It was also recognized that telemedicine may increase instead of reduce health care disparities.

One-Stop-Shop Cancer Screening Clinic: Acceptability Testing.

Cancer screenings aid in the early detection of cancer and can help reduce cancer-related mortality. The current model of care for cancer screening is often siloed, based on the targeted cancer site. We tested the acceptability of a new model of care, called the One-Stop-Shop Cancer Screening Clinic, that centralizes cancer screenings and offers patients the option to complete all their recommended cancer screenings within one to two visits. We administered surveys to 59 community members and 26 healthcare providers to gather feedback about the One-Stop-Shop model of care. Both community members and providers identified potential benefits (e.g., decreased patient burden, increased completion of cancer screenings) and also potential challenges (e.g., challenges with workflow and timing of care) of the model of care. The results of the study support the acceptability of the model of care. Of the community members surveyed, 89.5% said, if offered, they would be interested in participating in the One-Stop-Shop Cancer Screening Clinic. Future studies are needed to formally evaluate the impact and cost effectiveness of the One-Stop-Shop Cancer Screening Clinic.

Antimicrobial Susceptibility Testing Performed in RPMI 1640 Reveals Azithromycin Efficacy against Carbapenem-Resistant Acinetobacter baumannii and Predicts In Vivo Outcomes in Galleria mellonella.

Antimicrobial susceptibility testing (AST) in RPMI 1640, a more physiologically relevant culture medium, revealed that a substantial proportion of carbapenem-resistant Acinetobacter baumannii isolates were susceptible to azithromycin, a macrolide antibiotic not currently considered effective against A. baumannii. Experiments using Galleria mellonella validated these in vitro data. Our finding that RPMI 1640's predictive accuracy for in vivo outcomes is superior to that of Mueller-Hinton II broth also supports the use of more physiologically relevant AST culturing conditions.

Interaction of hydrocortisone and illness severity on head growth in cohort of ELBW infants.

BACKGROUND: Extremely low birth weight (ELBW) infants comprise a fragile population at risk for neurodevelopmental disabilities (NDD). Systemic steroids were previously associated with NDD, but more recent studies suggest hydrocortisone (HCT) may improve survival without increasing NDD. However, the effects of HCT on head growth adjusted for illness severity during NICU hospitalization are unknown. Thus, we hypothesize that HCT will protect head growth, accounting for illness severity using a modified neonatal Sequential Organ Failure Assessment (M-nSOFA) score. METHODS: We conducted a retrospective study that included infants born at 23-29 weeks gestational age (GA) and < 1000 g. Our study included 73 infants, 41% of whom received HCT. RESULTS: We found negative correlations between growth parameters and age, similar between HCT and control patients. HCT-exposed infants had lower GA but similar normalized birth weights; HCT-exposed infants also had higher illness severity and longer lengths of hospital stay. We found an interaction between HCT exposure and illness severity on head growth, such that infants exposed to HCT had better head growth compared to those not exposed to HCT when adjusted for illness severity. CONCLUSION: These findings emphasize the importance of considering patient illness severity and suggest that HCT use may offer additional benefits not previously considered. IMPACT: This is the first study to assess the relationship between head growth and illness severity in extremely preterm infants with extremely low birth weights during their initial NICU hospitalization. Infants exposed to hydrocortisone (HCT) were overall more ill than those not exposed, yet HCT exposed infants had better preserved head growth relative to illness severity. Better understanding of the effects of HCT exposure on this vulnerable population will help guide more informed decisions on the relative risks and benefits for HCT use.

Multigenerational Impacts of Childhood Access to the Safety Net: Early Life Exposure to Medicaid and the Next Generation's Health.

We examine multi-generational impacts of positive in utero health interventions using a new research design that exploits sharp increases in prenatal Medicaid eligibility that occurred in some states. Our analyses are based on U.S. Vital Statistics Natality files, which enables linkages between individuals' early life Medicaid exposure and the next generation's health at birth. We find evidence that the health benefits associated with treated generations' early life program exposure extend to later offspring. Our results suggest that the returns on early life health investments may be substantively underestimated.

Coastal heritage, global climate change, public engagement, and citizen science.

Climate change is threatening an uncalculated number of archaeological sites globally, totaling perhaps hundreds of thousands of culturally and paleoenvironmentally significant resources. As with all archaeological sites, they provide evidence of humanity's past and help us understand our place in the present world. Coastal sites, clustered at the water's edge, are already experiencing some of the most dramatic damage due to anthropogenic climate change, and the situation is predicted to worsen in the future. In the face of catastrophic loss, organizations around the world are developing new ways of working with this threatened coastal resource. This paper uses three examples from Scotland, Florida, and Maine to highlight how new partnerships and citizen science approaches are building communities of practice to better manage threatened coastal heritage. It compares methods on either side of the Atlantic and highlights challenges and solutions. The approaches are applicable to the increasing number of heritage sites everywhere at risk from climate change; the study of coastal sites thus helps society prepare for climate change impacts to heritage worldwide.

Recent Telehealth Utilization at a Large Federally Qualified Health Center System: Evidence of Disparities Even Within Telehealth Modalities.

Objective: To explore overall trends as well as racial/ethnic disparities in utilization of different telehealth modalities (telephone vs. televideo) at federally qualified health centers (FQHCs) during the COVID-19 pandemic. Methods: Using electronic health record data from a large New York-based FQHC system, we aggregated (separately) Behavioral Health and Family Practice visits per month occurring in-person, by telephone, or by televideo and graphed monthly trends in visits across the pre-pandemic, peak-pandemic, and post-peak-pandemic periods. We calculated fractions of visits conducted by modality for each patient demographic (race/ethnicity, primary language, age, gender, insurance type, and geography) and conducted bivariate assessments to test relationships between patient characteristics and modality. Results: Our data contained 121,072 unique patients and 811,105 visits overall. Telehealth use peaked in April 2020 but continued to account for a significant fraction of FQHC visits-nearly 25% (N = 4,908) of monthly Family Practice visits and a massive 98% (N = 14,173) of Behavioral Health visits as late as June 2021. Of all telehealth visits, nearly half were by telephone. Moreover, demographic factors differed between FQHC patients using telephone visits versus those using televideo: Black, non-English speaking, older, and Medicaid patients had significantly higher utilization of telephone visits than televideo visits (e.g., 25.9% of all Black patients' visits were via telephone vs. 17.1% via televideo; p < 0.001). In contrast, younger, Asian, and privately insured patients had significantly higher televideo visits. Conclusions: Our results suggest that telephone visits remain critical to the provision of health care for FQHC patients. They also suggest that disparities extend beyond the telehealth versus in-person dichotomy and inequities exist even within the type of telehealth used. This has implications for patient health, FQHC quality outcomes, as well as optimal Medicaid telehealth reimbursement policy.

Systematic Review of Colorectal Cancer Screening-Related Apps.

Background: In the United States, colorectal cancer (CRC) is the second leading cause of cancer death in men and women combined. The United States Preventive Services Task Force recommends that average risk adults have regular CRC screening to detect and prevent CRC. Despite published CRC screening guidelines, national CRC screening rates remain suboptimal. With the exponential increase in technology use and device ownership, many mobile health applications (apps) have been developed to improve health outcomes. There is great potential for smartphone or tablet apps to help improve CRC screening uptake, with the ultimate goal of reducing CRC morbidity and mortality. To date, there are no systematic reviews that have examined the publicly available, free apps that are related to CRC screening, and therefore, the quality and the content of these apps remain unknown. Objectives: The purpose of this study was to systematically review smartphone and tablet apps that could be used to improve CRC screening uptake. Methods: Apps available on the Google Play and Apple App stores that were compatible with smartphones and tablets were reviewed. Of the 2,790 apps reviewed, 20 met inclusion criteria. Results: Of the 20 apps that met inclusion criteria, most were informational in nature. Approximately half of the apps focused on colonoscopies and did not discuss other CRC screening options. Furthermore, more than half of the apps did not include video/audio content and the majority of the apps did not provide navigation support (e.g., reminders, instructions, maps). Conclusions: There are multiple free, publicly available apps that may encourage CRC screening uptake. Despite their promise, there is a paucity of empirical evidence evaluating the efficacy and usability of these apps. Future research efforts can evaluate the content, usability, accessibility, and potential impact of these apps.

Barriers to Telehealth Utilization Among Patients of Limited Income with Chronic Conditions and a Gap in Care.

Objective: This study assessed barriers and facilitators to telehealth utilization among patients living in New York City public housing with chronic conditions and a gap in clinical care. Methods: Community health workers performed outreach to eligible patients by telephone between January and March 2021. Consenting respondents answered questions about telehealth barriers, including internet and cell phone access, ownership of digital devices, comfort with using digital devices, comfort with telehealth, cost, awareness, and availability of written materials in patients' preferred language. We obtained demographic and medical information from patients' electronic health records. We used multivariable logistic regression to estimate the association of barriers with the odds of self-reported prior telehealth utilization. Results: A total of 304 consenting patients participated in the program. The average patient had 3.1 telehealth barriers; 76% reported at least one barrier. Regression analysis showed sizable reductions in prior telehealth utilization associated with the barriers of unlimited cell phone minutes (odds ratio [OR]: 0.21 [0.05-0.88], p = 0.033), technological comfort (OR: 0.33 [0.13-0.82], p = 0.016), conceptual comfort with telehealth (OR: 0.15 [0.04-0.54], p = 0.004), and materials in the patient's preferred language (OR: 0.23 [0.07-0.79], p = 0.02). Discussion: With a high prevalence of telehealth barriers, patients with limited income, a chronic condition, and a care gap may benefit from greater technological access and supportive programs for awareness, telehealth comfort, and navigation support. Addressing telehealth barriers could increase the quality of medical care and improve health outcomes for this population.
