RESUMO
PURPOSE OF REVIEW: Despite continuous innovations and federal investment to create digital interventions addressing the HIV prevention and care continua, these interventions have not reached people in the U.S. at scale. This article reviews what is known about U.S. implementation of digital HIV interventions and presents a strategy to cross the research-to-practice chasm for these types of interventions. RECENT FINDINGS: We conducted a narrative review of U.S.-based original research on implementation of digital HIV interventions and identified few studies reporting on implementation determinants, strategies, processes, or outcomes, particularly outside the context of effectiveness trials. To supplement the literature, in 2023, we surveyed 47 investigators representing 64 unique interventions about their experiences with implementation after their research trials. Respondents placed high importance on intervention implementation, but major barriers included lack of funding and clear implementation models, technology costs, and difficulty identifying partners equipped to deliver digital interventions. They felt that responsibility for implementation should be shared between intervention developers, deliverers (e.g., clinics), and a government entity. If an implementation center were to exist, most respondents wanted to be available for guidance or technical assistance but largely wanted less involvement. Numerous evidence-based, effective digital interventions exist to address HIV prevention and care. However, they remain "on the shelf" absent a concrete and sustainable model for real-world dissemination and implementation. Based on our findings, we call for the creation of national implementation centers, analogous to those in other health systems, to facilitate digital HIV intervention delivery and accelerate progress toward ending the U.S. epidemic.

Existing HIV prevention interventions, such as pre-exposure prophylaxis (PrEP), and behavioral health treatments inadequately reach Latino men who have sex with men (LMSM) in the US. This study involved formative research to inform the content, design, and implementation of a scalable, low resource implementation strategy - peer ambassador stories - stories from peers to normalize using PrEP, HIV testing, and behavioral health treatment. We conducted semi-structured interviews with 20 LMSM to elucidate their content, design, and implementation preferences for peer ambassador stories. Men were asked about story prompts, story contributor characteristics, story platform features, design preferences, and recommendations for enhancing the adoption and use of the peer ambassador technology platform among LMSM. Interviews were transcribed and analyzed via rapid qualitative analysis. Qualitative analyses identified 14 themes within 4 pre-specified domains. Collectively, the themes unified around the central concept that technology-delivered peer ambassador stories require a personalized, relational, culturally relevant touch to be acceptable and appropriate for LMSM. This study suggests that disseminating peer ambassador stories using electronic platforms and audio/video formats may enhance the reach of services and if they are personalized, relational, and culturally relevant. Findings have broad implications for informing other peer-based strategies to mitigate HIV disparities among LMSM.

Awareness and uptake of the meningitis vaccine remains low among marginalized groups, such as Latino men who have sex with men (LMSM), potentially due to structural and psychosocial barriers in accessing preventative healthcare. The current study explored awareness and uptake of meningitis vaccines among a group of LMSM (N = 99) living in South Florida. A three-pronged variable selection approach was utilized prior to conducting regression models (linear and logistic). Overall, 48.5% of the participants reported little to no knowledge about meningitis vaccines, and 20.2% reported being vaccinated. Living with HIV (OR = 10.48) and time since outbreak (OR = 1.03) were significant predictors of meningitis vaccine uptake. No significant correlates of meningitis vaccine awareness were identified. More research is needed to identify other important factors associated with meningitis vaccine awareness and uptake among LMSM, a multiple marginalized group.

Adolescent men who have sex with men (AMSM) have a high HIV incidence and low utilization of testing and prevention services. However, very few HIV prevention programs exist that focus on the unique sexual health needs of AMSM. SMART is a stepped care package of eHealth interventions that comprehensively address the sexual and HIV prevention needs of AMSM. This study examines the impact of the first step of SMART, "SMART Sex Ed," on 13- to 18-year-old AMSM (n = 983) from baseline to three-month follow-up across 18 separate outcomes measuring HIV prevention attitudes, skills, and behaviors. We observed significant change from baseline to three-month post-intervention in nine HIV-related outcomes (e.g., receipt of HIV and STI test, HIV knowledge), as well as largely consistent effects across demographic subgroups (e.g., race, age, rural, low SES). Analyses observed no effects on condom use behaviors. SMART Sex Ed shows promise as an effective sexual health education program for diverse AMSM.
RESUMEN: Los adolescentes hombres que tienen sexo con otros hombres (AHSH) experimentan alta incidencia del VIH y baja utilización de servicios de prueba y prevención. Sin embargo, existen muy pocos programas de prevención del VIH enfocados en las necesidades particulares para la salud sexual de AHSH. SMART es un paquete de intervenciones de cuidado escalonado que usa plataformas electrónicas (eHealth) y que atiende de forma integrada las necesidades de salud sexual y prevención del VIH de AHSH. Este estudio examina el impacto de la primera etapa de SMART, llamada "SMART Sex Ed", entre AHSH (n = 983) entre las edades de 13 a 18 años e integra datos desde el reclutamiento con seguimiento cada 3 meses. Se recopilaron datos de 18 indicadores de actitudes, destrezas y prácticas de prevención del VIH (Ej. Historial de pruebas de VIH o ITS; conocimiento sobre VIH), así como los efectos en diferentes grupos demográficos (Ej. Raza, edad, área rural, y bajo nivel socioeconómico). Los análisis realizados demuestran que las características demográficas no tienen efecto en las prácticas de uso de condón. SMART Sex Ed es una intervención prometedora para educación sexual efectiva para AHSH.

Background: Mobile health tools may be effective strategies to improve engagement, education, and diabetes-related health during pregnancy. We developed SweetMama, a patient-centered, interactive mobile application (app) designed to support and educate low-income pregnant people with diabetes. Our objective was to evaluate the SweetMama user experience and acceptability. Methods: SweetMama is a mobile app with static and dynamic features. Static features include a customized homepage and resource library. Dynamic features include delivery of a theory-driven diabetes-specific curriculum via 1) motivational, tip, and goal-setting messages aligning with treatment and gestational age; 2) appointment reminders; and 3) ability to mark content as "favorite." In this usability assessment, low-income pregnant people with gestational or type 2 diabetes used SweetMama for 2 weeks. Participants provided qualitative feedback (via interviews) and quantitative feedback (via validated usability/satisfaction measures) on their experience. User analytic data detailed the duration and type of interactions users had with SweetMama. Results: Of 24 individuals enrolled, 23 used SweetMama and 22 completed exit interviews. Participants were mostly non-Hispanic Black (46%) or Hispanic (38%) individuals. Over the 14-day period, users accessed SweetMama frequently (median number of log-ins 8 [interquartile range 6-10]), for a median of 20.5 total minutes, and engaged all features. A majority (66.7%) rated SweetMama as having moderate or high usability. Participants emphasized design and technical strengths and beneficial effects on diabetes self-management and also identified limitations of the user experience. Conclusion: Pregnant people with diabetes found SweetMama to be user-friendly, informative, and engaging. Future work must study its feasibility for use throughout pregnancy and its efficacy to improve perinatal outcomes.
RESUMO
We investigated whether the antibody response to coronavirus disease 2019 (COVID-19) mRNA vaccination is similar in women and men. In a community cohort without prior COVID-19, first vaccine dose produced higher immunoglobulin G (IgG) levels and percent inhibition of spike-ACE2 receptor binding, a surrogate measure of virus neutralization, in women compared to men (7.0 µg/mL, 51.6% vs 3.3 µg/mL, 36.4%). After 2 doses, IgG levels remained significantly higher for women (30.4 µg/mL) compared to men (20.6 µg/mL), while percent inhibition was similar (98.4% vs 97.7%). Sex-specific antibody response to mRNA vaccination informs future efforts to understand vaccine protection and side effects.

BACKGROUND: Health workforce planning is critical for health systems to safeguard the ability to afford, train, recruit, and retain the appropriate number and mix of health workers. This balance is especially important when macroeconomic structures are also reforming. The Kingdom of Saudi Arabia is moving toward greater diversification, privatization, and resiliency; health sectorreform is a key pillar of this transition. METHODS: We used the Ministry of Health Yearbook data on the number of workers and health expenditures from 2007 to 2018 and projected health labor market supply and demand of workers through 2030, evaluated the potential shortages and surpluses, and simulated different policy scenarios to identify relevant interventions. We further focused on projections for health workers who are Saudi nationals and health worker demand within the public sector (versus the private sector) to inform national objectives of reducing dependency on foreign workers and better deploying public sector resources. RESULTS: We projected the overall health labor market to demand 9.07 physicians and nurses per 1,000 population (356,514) in 2030; the public sector will account for approximately 67% of this overall demand. Compared to a projected supply of 10.16 physicians and nurses per 1,000 population (399,354), we estimated an overall modest surplus of about 42,840 physicians and nurses in 2030. However, only about 17% of these workers are estimated to be Saudi nationals, for whom there will be a demand shortage of 287,895 workers. Among policy scenarios considered, increasing work hours had the largest effect on reducing shortages of Saudi workers, followed by bridge programs for training more nurses. Government resources can also be redirected to supporting more Saudi nurses while still ensuring adequate numbers of physicians to meet service delivery goals in 2030. CONCLUSION: Despite projected overall balance in the labor market for health workers in 2030, without policy interventions, severe gaps in the Saudi workforce will persist and limit progress toward health system resiliency in Saudi Arabia. Both supply- and demand-side policy interventions should be considered, prioritizing those that increase productivity among Saudi health workers, enhance training for nurses, and strategically redeploy financial resources toward employing these workers.

Adolescent men who have sex with men (AMSM) experience a dramatic health disparity in HIV, accounting for over 80% of new diagnoses among youth. Current evidence-based HIV prevention programs, however, focus primarily on adults and heterosexual youth, thereby missing the unique experiences and socio-environmental contexts of AMSM aged 13-18. To address these gaps, we used the Intervention Mapping (IM) protocol to developmentally adapt an existing evidence-based online HIV risk reduction program (i.e., Keep it Up!/KIU!), originally designed for young adult MSM aged 18-29, into a new intervention called SMART Squad. Using a hybrid of IM creation and adaptation tasks, we specified three behavioral outcomes and identified corresponding performance objectives for SMART Squad based on the original goals of KIU!. We constructed matrices of change objectives using determinants from the Information-Motivation-Behavioral Skills model, modifying them for the younger population with additional theoretical and empirical evidence and expert review. SMART Squad activities were operationalized from theory-based behavior change methods matched to the change objectives and guided by program themes, components, and scope imported from KIU!. The final SMART Squad intervention comprises 6 episodes/modules delivered in 2 sessions plus 2 booster episodes occurring 1 and 3 months after the main program. It is currently being evaluated nationally as part of a stepped-care package of 3 programs, in which the receipt and sequencing of interventions is tailored to individual AMSM development and needs. Despite substantial changes to KIU!, IM was a useful method for retaining the hypothesized essential elements of the eHealth HIV risk reduction program. Challenges and recommendations for future researchers and practitioners are discussed.

BACKGROUND: The risk for developing cardiovascular disease is greater in patients with rheumatoid arthritis (RA) than in the general population. While patients with RA also have dyslipidemia, the impact of dyslipidemia on the severity of inflammatory arthritis and associated cardiovascular disease is unclear. Currently, there are conflicting results regarding arthritis incidence in apolipoprotein E (ApoE) deficient mice, which spontaneously exhibit both hyperlipidemia and atherosclerosis. Here, we utilize a distinct approach to investigate the contribution of a hyperlipidemic environment on the development of arthritis and atherosclerosis in mice lacking ApoE. METHODS: K/BxN serum transfer-induced arthritis (STIA) was assessed in C57BL/6 (control) and ApoE(-/-) mice using clinical indices and immunohistochemical staining. Ankle synoviums were processed for flow cytometry. Aortic atherosclerosis was quantitated using Sudan IV staining. Serum cholesterol and cytokine levels were determined via enzymatic and luminex bead-based assays, respectively. RESULTS: ApoE(-/-) mice developed a sustained and enhanced semi-chronic inflammatory arthritis as compared to control mice. ApoE(-/-) mice had increased numbers of foamy macrophages, enhanced joint inflammation and amplified collagen deposition versus controls. The presence of arthritis did not exacerbate serum cholesterol levels or significantly augment the level of atherosclerosis in ApoE(-/-) mice. However, arthritic ApoE(-/-) mice exhibited a marked elevation of IL-6 as compared to non-arthritic ApoE(-/-) mice and arthritic C57BL/6 mice. CONCLUSIONS: Loss of ApoE potentiates a semi-chronic inflammatory arthritis. This heightened inflammatory response was associated with an increase in circulating IL-6 and in the number of foamy macrophages within the joint. Moreover, the foamy macrophages within the arthritic joint are reminiscent of those within unstable atherosclerotic lesions and suggest a pathologic role for foamy macrophages in propagating arthritis.

Caspase-8, an executioner enzyme in the death receptor pathway, was shown to initiate apoptosis and suppress necroptosis. In this study, we identify a novel, cell death-independent role for caspase-8 in dendritic cells (DCs): DC-specific expression of caspase-8 prevents the onset of systemic autoimmunity. Failure to express caspase-8 has no effect on the lifespan of DCs but instead leads to an enhanced intrinsic activation and, subsequently, more mature and autoreactive lymphocytes. Uncontrolled TLR activation in a RIPK1-dependent manner is responsible for the enhanced functionality of caspase-8-deficient DCs, because deletion of the TLR-signaling mediator, MyD88, ameliorates systemic autoimmunity induced by caspase-8 deficiency. Taken together, these data demonstrate that caspase-8 functions in a cell type-specific manner and acts uniquely in DCs to maintain tolerance.

The extent and clinical significance of stem and progenitor cell (SPC) increases in response to lower-extremity ischemia in people with peripheral artery disease (PAD) are unclear. We compared changes in SPC levels immediately following a treadmill exercise test between individuals with and without PAD. Among participants with PAD, we determined whether more severe PAD was associated with greater increases in SPCs following treadmill exercise-induced lower-extremity ischemia. We measured SPC levels in 25 participants with PAD and 20 without PAD before and immediately after a treadmill exercise test. Participants with PAD, compared to participants without PAD, had greater increases in CD34(+)CD45(dim) (+0.08±0.03 vs -0.06±0.04, p=0.008), CD34(+)CD45(dim)CD133(+) (+0.08±0.05 vs -0.08±0.04, p=0.014), CD34(+)CD45(dim)CD31(+) (+0.10±0.03 vs -0.07±0.04, p=0.002), and CD34(+)CD45(dim)ALDH(+) SPCs (+0.18±0.07 vs -0.05±0.08, p=0.054) measured as a percentage of all white blood cells. Among participants with PAD, those with any increases in the percent of SPCs immediately after the treadmill exercise test compared to those with no change or a decrease in SPCs had lower baseline ankle-brachial index values (0.65±0.17 vs 0.90±0.19, p=0.004) and shorter treadmill times to onset of ischemic leg symptoms (2.17±1.54 vs 5.25±3.72 minutes, p=0.012). In conclusion, treadmill exercise-induced lower-extremity ischemia is associated with acute increases in circulating SPCs among people with PAD. More severe PAD is associated with a higher prevalence of SPC increases in response to lower-extremity ischemia. Further prospective study is needed to establish the prognostic significance of ischemia-related increases in SPCs among patients with PAD.

BACKGROUND: Despite being the primary setting for HIV prevention among men who have sex with men (MSM) since the start of the epidemic, community-based organizations (CBOs) struggle to reach this historically stigmatized and largely hidden population with face-to-face interventions. HIV researchers have readily turned to the internet to deliver critical HIV education to this group, with evidence of high effectiveness and acceptability across studies. However, implementation outside of research contexts has been limited and not well studied. We aimed to assess HIV CBOs' readiness to adopt digital health interventions and identify contextual factors that may contribute to differing levels of readiness. METHODS: We recruited 22 CBOs across the US through a pragmatic request-for-proposals process to deliver Keep It Up! (KIU!), an evidence-based eHealth HIV prevention program. We used mixed methods to examine CBO readiness to adopt digital health interventions (RADHI). Before implementation, CBO staff completed a 5-item RADHI scale (scored 0-4) that demonstrated concurrent and predictive validity. We interviewed CBO staff using semi-structured questions guided by the Consolidated Framework for Implementation Research and compared RADHI score groups on determinants identified from the interviews. RESULTS: Eighty-five staff (range = 1-10 per CBO) completed the RADHI. On average, CBOs reported moderate-to-great readiness (2.74) to adopt KIU!. High RADHI CBOs thought KIU! was a top priority and an innovative program complementary to their existing approaches for their clients. Low RADHI CBOs expressed concerns that KIU! could be a cultural mismatch for their clients, was lower priority than existing programs and services, relied on clients' own motivation, and might not be suitable for clients with disabilities. Value, appeal, and limitations did not differ by RADHI group. CONCLUSIONS: While HIV CBOs are excited for the opportunities and advantages of digital interventions, additional pre-implementation and implementation support may be needed to increase perceived value and usability for different client populations. Addressing these limitations is critical to effective digital prevention interventions for HIV and other domains such as mental health, chronic disease management, and transitions in care. Future research can utilize our novel, validated measure of CBOs' readiness to adopt digital health interventions. TRIAL REGISTRATION: NCT03896776, clinicaltrials.gov, 1 April 2019.
RESUMO
The COVID-19 pandemic has dramatically threatened the Gulf Cooperation Council (GCC) countries which have a large proportion of foreign workers. The governments of GCC countries have proactively implemented a comprehensive set of policy measures, and up to our knowledge, a systematic analysis of qualitative and quantitative evidence on the government response is still lacking. We summarized the GCC countries' government response and quantitatively measured that response using four indexes-the Government Response Index, the Stringency Index, the Vaccine Index, and the Initial Response Index, to analyse their response for future pandemic preparedness. Overall, the government response of all the GCC countries to the COVID-19 pandemic has been comprehensive, stringent, and timely. Notably, the GCC countries have implemented comprehensive vaccine policies. In addition, they have worked actively to protect foreign workers to improve their access to health services and secure their essential living conditions, regardless of their immigrant status. All the GCC countries dynamically adjusted their response to the evolving COVID-19 epidemiological burden and started to relax the stringency of the control policies after the Omicron wave, though the governments had different response magnitudes as measured by the four indexes. These findings have provided several important lessons for future pandemic response and preparedness for countries with similar economic, demographic, and health contexts in (1) prompt actions of containment and closure policies with dynamic adjusting, (2) strengthening health system policies, (3) comprehensive vaccination policies with universal access, (4) equitable and free access to testing, diagnosis, and treatment for all, and (5) strengthening the resilience of health systems.

We examined the acceptability of Humpr - an interactive, online tool developed to educate adolescent sexual minority males (ASMM) about how to safely navigate sexual networking applications (SNA). We developed Humpr as part of a larger HIV intervention trial in the U.S. In Humpr, 218 ASMM aged 14-20 (Mage = 17.18) created a mock dating profile, explored simulated user profiles, learned health-related information (e.g. slang indicating HIV/STI risks and/or drug use intentions), and then gave feedback regarding acceptability of the tool. Results showed that Humpr was very well-received, with 94% overall approval rates. Reasons for liking Humpr were evenly split between liking it for educational and entertaining reasons. Participants praised Humpr for its realistic design and interactive interface that allowed them to engage and connect with the tool. The majority (61%) had used SNAs in the past, but many still reported learning something new from Humpr. Participants also appreciated the acknowledgment of SNA use in ASMM and how the education was implemented in an open and judgment-free way. Topics learned from Humpr included how to be safe on SNAs and warning signs for HIV/STI risks. Suggested areas of improvement included having an opt-out option for those who do not wish to participate for any reason (e.g. discomfort) and additional educational content (e.g. consequences of being a minor on SNAs). Taken together, the findings offer preliminary evidence for the potential educational benefits of digital tools like Humpr for ASMM with and without prior SNA exposure.
RESUMO
BACKGROUND: Despite evidence that eHealth approaches can be effective in reducing HIV risk, their implementation requirements for public health scale up are not well established, and effective strategies to bring these programs into practice are still unknown. Keep It Up! (KIU!) is an online program proven to reduce HIV risk among young men who have sex with men (YMSM) and ideal candidate to develop and evaluate novel strategies for implementing eHealth HIV prevention programs. KIU! 3.0 is a Type III Hybrid Effectiveness-Implementation cluster randomized trial designed to 1) compare two strategies for implementing KIU!: community-based organizations (CBO) versus centralized direct-to-consumer (DTC) recruitment; 2) examine the effect of strategies and determinants on variability in implementation success; and 3) develop materials for sustainment of KIU! after the trial concludes. In this article, we describe the approaches used to achieve these aims. METHODS: Using county-level population estimates of YMSM, 66 counties were selected and randomized 2:1 to the CBO and DTC approaches. The RE-AIM model was used to drive outcome measurements, which were collected from CBO staff, YMSM, and technology providers. Mixed-methods research mapped onto the domains of the Consolidated Framework for Implementation Research will examine determinants and their relationship with implementation outcomes. DISCUSSION: In comparing our implementation recruitment models, we are examining two strategies which have shown effectiveness in delivering health technology interventions in the past, yet little is known about their comparative advantages and disadvantages in implementation. The results of the trial will further the understanding of eHealth prevention intervention implementation.

Adolescent men who have sex with men (AMSM) experience high rates of HIV diagnoses and low utilization of HIV testing and prevention services. Meta-analyses and literature reviews have reported significant effects of online programs at reducing HIV and STI risk and improving use of protective behaviors. SMART is a stepped care package of eHealth interventions that comprehensively address the sexual health and HIV prevention needs of diverse 13-18 year old AMSM nationwide. As part of the online curriculum, educational tools were created to promote specific learning objectives, including the importance of STI and HIV testing. This study describes the use of an HIV and STI testing center locator custom designed for the SMART intervention to promote STI and HIV testing in AMSM. Data were collected between April 2018 and July 2020 as part of the SMART trial assessing the impact of the first intervention of the SMART program, titled SMART Sex Ed, on 13-18 year old AMSM. Measures included AMSM interaction data with the locator tool, history of HIV and STI testing, and confidence to get tested at baseline and 3 months post intervention. Upon entering the SMART program, most participants (69.3%) had never received an HIV or STI test in their lifetime. From those who were enrolled in SMART Sex Ed (n=1075), 82.6% used the custom developed HIV and STI testing center locator tool and those who used the tool were significantly more confident to receive an HIV test and STI test (p < 0.01). Qualitative feedback from SMART participants described the tool as interactive, useful, and easy to use. Preliminary data analysis suggests that our custom developed HIV and STI testing center locator is an acceptable and useful tool with potential for implementation outside the SMART Program. Future analysis should examine if the testing center locator is an acceptable and effective tool outside of the SMART intervention package. Given these results, providing AMSMs easy to use and acceptable online tools with comprehensive, culturally relevant didactic content can significantly improve AMSM's utilization of HIV testing and prevention services.
RESUMO
BACKGROUND: Mobile health (mHealth) technology that addresses diabetes mellitus in pregnancy has the potential to improve maternal and child health while diminishing socioeconomic and racial disparities. Little is known about health literacy, electronic health literacy, or patient characteristics that contribute to increased mHealth use. In this pilot study, we aimed to examine patient factors associated with user engagement with a novel app for diabetes support during pregnancy. METHOD: Low-income pregnant individuals with gestational or type 2 diabetes mellitus were recruited for a 2-week usability assessment of a novel mHealth smartphone application, "SweetMama," designed to improve diabetes care. This analysis of user characteristics was a pilot assessment of data from the usability study phase. Participants completed assessments of patient health literacy, electronic health literacy, diabetes self-efficacy, and activation. User metrics (eg, sessions and total duration of use) were evaluated by participant characteristics. Descriptive analyses were conducted to assess outcomes with respect to patient's clinical history, health literacy, electronic health literacy, diabetes self-efficacy, and activation. RESULTS: Twenty-two diverse, low-income pregnant patients with either gestational or type 2 diabetes engaged with SweetMama for 14 days. Participants with gestational diabetes had greater mean minutes of use per session and mean total duration of use than those with type 2 diabetes. Participants with greater electronic health literacy, lower patient activation, and greater self-efficacy demonstrated greater total duration of use. No user metrics differed significantly by participant general health literacy. CONCLUSIONS: Findings of this pilot study suggest engagement with a novel mHealth app for diabetes support during pregnancy varied by baseline behavioral and clinical characteristics. Results could indicate that digital health literacy better differentiates engagement patterns than general health literacy.

SARS-CoV-2 vaccines protect against symptomatic and severe COVID-19. The BNT162b2/Pfizer and mRNA-1273/Moderna vaccines represent new vaccine technology relying on administration of mRNA encoding SARS-CoV-2 viral spike protein encased in lipid nanoparticles. The vaccines are administered as two doses into muscle, which elicits a strong response, typically within 14 days after the second dose. Neuromuscular diseases are characterized by the progressive loss of muscle and are often treated with chronic glucocorticoid steroids, both of which may contribute to a blunted immune response to vaccination. Here, we measured IgG antibody content and neutralizing antibody response after mRNA COVID-19 vaccination in non-ambulatory neuromuscular disease patients. After two doses of mRNA COVID-19 vaccine, median anti-receptor binding domain IgG and percent surrogate viral neutralization in non-ambulatory neuromuscular disease samples were significantly elevated similar to healthy vaccinated controls. As in healthy controls, COVID-19 vaccines produce greater antibody levels compared to those with a history of outpatient COVID-19 infection. This data documents that non-ambulatory neuromuscular disease patients respond well to two doses of mRNA COVID-19 vaccine despite low muscle mass and even chronic steroid use.

Background: E-government platforms provide an opportunity to use a novel data source for population health surveillance (also known as e-health). Absher is a Saudi e-government platform with 23 million authenticated users, including residents and citizens in Saudi Arabia. All Absher users were invited to participate in a web-based survey to estimate the prevalence of noncommunicable diseases and their risk factors in Saudi Arabia. Objective: To assess the potential of using an e-government platform (Absher) to administer web-based health surveys. Methods: A cross-sectional, web-based health survey was administered to Absher users between April 2019 and March 2020. The survey instrument included eight items and took <5 min to complete. The respondents' data were compared to Saudi Arabia's 2016 census. Descriptive summary statistics of the prevalence of major noncommuncable diseases are presented and compared to population-based prevalence data from Saudi Arabia's World Health Survey (WHS) 2019. All analysis was conducted using Stata 13.0. Results: Overall, the Absher health survey had a 24.6% response rate, with most respondents being male (84%), Saudi (67%), and between 30 and 44 years of age (49%). Overall, the prevalence of noncommunicable diseases and risk factors among respondents was high for overweight (35%) and obesity (30%) and low for asthma (6%). The prevalence of diabetes, dyslipidemia, and hypertension was between 15 and 17% on average, and 26.5% were smokers. In comparison to population-based World Health Survey estimates, the Absher survey overestimated obesity, diabetes, dyslipidemia, hypertension, and smoking rates, and underestimated overweight, whereas asthma prevalence was similar for Absher and the WHS. Conclusions: With improvements in the study design, the use of e-government platforms can provide a useful and potentially low-cost data source for public health research.
