Lyme disease is a zoonotic infection due to Ixodes tick–transmitted Borrelia burgdorferi sensu lato spirochetes and the most common vector-borne disease in the Northern Hemisphere. Despite nearly 50 years of investigation, the pathogenesis of this infection and its 2 main adverse outcomes—postinfectious Lyme arthritis and posttreatment Lyme disease syndrome—are incompletely understood. Advancement in sequencing and mass spectrometry have led to the rapid expansion of high-throughput omics technologies, including transcriptomics, metabolomics, and proteomics, which are now being applied to human diseases. This review summarizes findings of omics studies conducted on blood and tissue samples of people with acute Lyme disease and its postinfectious outcomes. [ABSTRACT FROM AUTHOR]

Background: The human reward system has been extensively studied using neuroimaging. This bibliometric analysis aimed to determine the global trend in diffusion magnetic resonance imaging (dMRI) and human reward research in terms of the number of documents, the most active countries and their collaborating countries, the top journals and institutions, the most prominent authors and most cited articles, and research hotspots. Methods: The research datasets were acquired from the Scopus database. The search terms used were 'reward' AND 'human' AND 'diffusion imaging' OR 'diffusion tensor imaging' OR 'diffusion MRI' OR 'diffusion-weighted imaging' OR 'tractography' in the abstract, article title and keywords. A total of 336 publications were analysed using Harzing's Publish or Perish and VOSviewer software. Results: The results revealed an upward trend in the number of publications with the highest number of articles in 2020 and 2022. Most publications were limited to countries, authors, and institutions in the USA, China and Europe. Bracht, Coenen, Wiest, Federspiel and Feng were among the top authors from Switzerland, Germany and the UK. Neuroimage, Neuroimage Clinical, Frontiers in Human Neuroscience, Human Brain Mapping, and the Journal of Neuroscience were the top journals. Among the top articles, six were reviews and four were original articles, while the top keywords in human reward research were 'diffusion MRI', 'adolescence', 'depression' and 'reward-related brain areas'. Conclusion: These findings may serve as researchers' references to find collaborative authors, relevant journals, cooperative countries/institutions, and hot topics related to dMRI and reward research.

Lung cancer is the leading cause of mortality and person‐years of life lost from cancer among US men and women. Early detection has been shown to be associated with reduced lung cancer mortality. Our objective was to update the American Cancer Society (ACS) 2013 lung cancer screening (LCS) guideline for adults at high risk for lung cancer. The guideline is intended to provide guidance for screening to health care providers and their patients who are at high risk for lung cancer due to a history of smoking. The ACS Guideline Development Group (GDG) utilized a systematic review of the LCS literature commissioned for the US Preventive Services Task Force 2021 LCS recommendation update; a second systematic review of lung cancer risk associated with years since quitting smoking (YSQ); literature published since 2021; two Cancer Intervention and Surveillance Modeling Network‐validated lung cancer models to assess the benefits and harms of screening; an epidemiologic and modeling analysis examining the effect of YSQ and aging on lung cancer risk; and an updated analysis of benefit‐to‐radiation‐risk ratios from LCS and follow‐up examinations. The GDG also examined disease burden data from the National Cancer Institute's Surveillance, Epidemiology, and End Results program. Formulation of recommendations was based on the quality of the evidence and judgment (incorporating values and preferences) about the balance of benefits and harms. The GDG judged that the overall evidence was moderate and sufficient to support a strong recommendation for screening individuals who meet the eligibility criteria. LCS in men and women aged 50–80 years is associated with a reduction in lung cancer deaths across a range of study designs, and inferential evidence supports LCS for men and women older than 80 years who are in good health. The ACS recommends annual LCS with low‐dose computed tomography for asymptomatic individuals aged 50–80 years who currently smoke or formerly smoked and have a ≥20 pack‐year smoking history (strong recommendation, moderate quality of evidence). Before the decision is made to initiate LCS, individuals should engage in a shared decision‐making discussion with a qualified health professional. For individuals who formerly smoked, the number of YSQ is not an eligibility criterion to begin or to stop screening. Individuals who currently smoke should receive counseling to quit and be connected to cessation resources. Individuals with comorbid conditions that substantially limit life expectancy should not be screened. These recommendations should be considered by health care providers and adults at high risk for lung cancer in discussions about LCS. If fully implemented, these recommendations have a high likelihood of significantly reducing death and suffering from lung cancer in the United States. [ABSTRACT FROM AUTHOR]

Background This study was the first human validation of the gram-positive bacterial DNA polymerase IIIC target in patients with Clostridioides difficile infection. The primary objectives were to assess clinical cure rates and adverse events (AEs). Secondary objectives were to evaluate plasma/fecal pharmacokinetics, microbiologic eradication, microbiome and bile acid effects, and sustained clinical cure (SCC) with ibezapolstat. Methods This single-arm, open-label, phase 2a study enrolled adults with C. difficile infection at 4 US centers. Patients received ibezapolstat 450 mg orally every 12 hours for 10 days and followed for an additional 28 days to assess study objectives. Results Ten patients with a mean (standard deviation [SD]) age of 49 [15] years were enrolled. Seven AEs were reported classified as mild-moderate. Plasma levels of ibezapolstat ranged from 233 to 578 ng/mL while mean (SD) fecal levels were 416 (494) µg/g stool by treatment day 3 and >1000 µg/g stool by days 8–10. A rapid increase in alpha diversity in the fecal microbiome was noted after starting ibezapolstat therapy, which was maintained after completion of therapy. A proportional decrease in Bacteroidetes phylum was observed (mean change [SD], −10.0% [4.8%]; P  = .04) with a concomitantly increased proportion of Firmicutes phylum (+14.7% [5.4%]; P  = .009). Compared with baseline, total primary bile acids decreased by a mean (SD) of 40.1 (9.6) ng/mg stool during therapy (P  < .001) and 40.5 (14.1) ng/mg stool after completion of therapy (P  = .007). Rates of both initial clinical cure and SCC at 28 days were 100% (10 of 10 patients). Conclusions In this phase 2a study, 10 of 10 patients achieved SCC, demonstrated favorable pharmacokinetics, minimal AEs, and beneficial microbiome and bile acids results. These results support continued clinical development. [ABSTRACT FROM AUTHOR]

This meta-analysis aims to estimate the pooled prevalence of mental disorders among COVID-19 survivors. The databases Pubmed, Google Scholar, ScienceDirect, and medRxiv have been searched up to 1 August 2021 using COVID-19, survivors, mental disorders, and their related MeSH terms. The included studies were either cross-sectional, cohort, or case–control in design. Those studies included COVID-19 survivors after 14 or more days from their COVID-19 recovery and used validated questionnaires to assess their mental health outcomes. The random-effects model was used to pool the data from the incorporated studies. The heterogeneity was assessed using Cochran's Q heterogeneity test and I2 statistic. Twenty-seven studies were included in the data synthesis with a total sample size of 9605 COVID-19 survivors. The prevalence rates for Post-Traumatic Stress Disorder (PTSD), anxiety, psychological distress, depression, and sleeping disorders were 20% (95% CI = 16–24%), 22% (95% CI = 18–27%), 36% (95% CI = 22–51%), 21% (95% CI = 16–28%), and 35% (95% CI = 29–41%), respectively. Although we found high heterogeneity across the included studies, our meta-analysis provides evidence that there are psychological sequelae in COVID-19 survivors that require medical assiduity as well as further research on the matter. Increased prevalence of psychological sequelae among COVID-19 survivors. The prevalence of PTSD was 20% (95% CI = 16–24%) and of anxiety was 22% (95% CI = 18–27%) among COVID-19 survivors. The prevalence of psychological distress was 36% (95% CI = 22–51%), of depression was 21% (95% CI = 16–28%), and of sleep disorders was 35% (95% CI = 29–41%) among COVID-19 survivors. Future researches are recommended to search for effective and safe methods to mitigate the psychological sequelae in COVID-19 patients. [ABSTRACT FROM AUTHOR]

The Civil War was the deadliest conflict in US history. However, incomplete records have made it difficult to estimate the exact death toll both nationally, and especially, at the state level. In this article, we leverage the recently released full count of individual census returns and a sample of linked records across multiple censuses to provide i) the most precise national estimate of excess mortality to date and ii) reliable state-level estimates of excess mortality among native-born white males. Our national estimate is 698,000 Civil War deaths. This is substantially higher than the conventional historical estimate of 618,000 but lower than the most recent estimate of around 750,000 deaths based on a 1% census sample. Leveraging a novel migration-adjusted census comparison method, we document the extent to which the war's toll was much greater in the Confederate states than in the Union., Competing Interests: Competing interests statement:The authors declare no competing interest.

We develop a game-theoretic model of strategic interdependence and tipping in public policy choices and show that the model can be estimated by probit and logit estimators. We test its validity and applicability by using daily data on state-level COVID-19 responses in the United States. Social distancing via shelter-in-place (SIP) strategies and wearing masks emerged as the most effective nonpharmaceutical ways of combatting COVID-19. In the United States, choices about these policies are made by individual states. We develop a game-theoretic model of such choices and test it econometrically, confirming strong interdependence in the implementation of these policies. If enough states engage in social distancing or mask wearing, others will be tipped to follow suit. Policy choices are influenced mainly by the choices of other states, especially those of similar political orientation and to a lesser degree by the number of new COVID-19 cases. The choice of mask-wearing policies is more sensitive to peer choices than the choice of SIP policies, and Republican states are much less likely than Democratic to introduce mask-wearing policies. The choices of policies are influenced more by political than public health considerations. These findings emphasize strategic interdependence in policy choice and offer an analytical framework for these complex dynamics., Competing Interests: Competing interests statement:The authors declare no competing interest.

Background and Objectives: Epidemiologic studies suggest increasing incidence and prevalence of myasthenia gravis (MG) among the elderly population outside the United States. We aimed to provide an estimation of MG incidence and prevalence and their trend among the Medicare Fee-For-Service (FFS)-covered elderly US population., Methods: We performed a retrospective longitudinal study using Medicare claims data (2006-2019). Study-eligible beneficiaries were aged 65 years and older, had at least 1 month of FFS Part A/B coverage, and were without any health maintenance organization insurance coverage. Study-eligible beneficiaries were aggregated into 2-year periods from 2006-2007 through 2018-2019. MG cases were ascertained using a validated algorithm of 2 MG claims within each 2-year period, from 2 outpatient office visits or a combination of 1 inpatient admission and 1 outpatient office visit, separated by ≥ 28 days. Period prevalence was calculated from MG-ascertained cases divided by FFS Part A/B beneficiaries and reported as cases per 100,000 population. Incident cases were determined among MG prevalent cases if the initial MG claim occurred in that period after a full calendar year since coverage initiation. Incidence was calculated as case counts per 100,000 at-risk beneficiary person-years (PYs) in each period excluding 2006-2007. Trends of prevalence and incidence over time were examined with Poisson regression. All-cause mortality of each 2-year period was calculated., Results: The period prevalence of MG increased from 81 to 119 per 100,000 FFS A/B population from 2006-2007 to 2018-2019 ( p < 0.001). Increasing trends of prevalence were observed in all sex (male/female), age (65-69/70-74/75-79/80+), race/ethnic (African American/Asian/Hispanics of any race/non-Hispanic White/other), and census region (Northeast/Midwest/South/West) subgroups. MG incidence increased from 12.2 to 13.3 per 100,000 PYs from 2008-2009 to 2018-2019 ( p < 0.05). Increasing incidence trends were significant in the following subgroups: men and women; all age groups except 75-79 years; White non-Hispanic race; Northeast, Midwest, and South census regions. All-cause mortality among MG beneficiaries was stable from 6.26 deaths per 100 PYs in 2006-2007 to 5.67 in 2018-2019 ( p = 0.18)., Discussion: Increasing trends in MG prevalence and incidence in the elderly US population, with variation in rates of certain subgroups, are confirmed in this 14-year period.

Background and Objectives: Mounting evidence points to a strong connection between cardiovascular risk during middle age and brain health later in life. The American Heart Association's Life's Essential 8 (LE8) constitutes a research and public health construct capturing key determinants of cardiovascular health. However, the overall effect of the LE8 on global, clinically relevant metrics of brain health is still unknown. We tested the hypothesis that worse LE8 profiles are associated with higher composite risk of the most important clinical endpoints related to poor brain health., Methods: We conducted a two-stage (discovery and replication) prospective study using data from the UK Biobank (UKB) and All of Us (AoU), 2 large population studies in the United Kingdom and the United States, respectively. The primary exposure was the LE8 score, a validated tool that captures 8 modifiable cardiovascular risk factors (blood pressure, glucose, cholesterol, body mass index, smoking, physical activity, diet, and sleep duration), organized in 3 categories (optimal, intermediate, and poor). The primary outcome was a composite of stroke, dementia, or late-life depression. We evaluated associations using multivariable Cox proportional hazard models., Results: The discovery stage included 316,127 UKB participants (mean age 56, 52% female). Over a mean (SD) follow-up time of 4.9 (0.4) years, the unadjusted risk of the composite outcome was 0.7% (95% CI 0.61-0.74), 1.2% (95% CI 1.11-1.22), and 1.8% (95% CI 1.70-1.91) in participants with optimal, intermediate, and poor cardiovascular health, respectively ( p < 0.001). This association remained significant in multivariable Cox models (intermediate vs optimal cardiovascular health hazard ratio [HR], 1.37; 95% CI 1.24-1.52, and poor vs optimal cardiovascular health HR, 2.11; 95% CI 1.88-2.36, p trend <0.001). The replication stage included 68,407 AoU participants (mean age 56, 60% female). Over a mean (SD) follow-up time of 2.9 (1.41) years, the unadjusted risk of the composite outcome was 2.8% (95% CI 2.49-3.05), 6% (95% CI 5.76-6.22), and 9.7% (95% CI 9.24-10.24) in participants with optimal, intermediate, and poor cardiovascular health, respectively ( p < 0.001). This association remained significant in multivariable Cox models (intermediate vs optimal cardiovascular health, HR 1.35; 95% CI 1.21-1.51, and poor vs optimal cardiovascular health, HR 1.94; 95% CI 1.72-2.18; p trend <0.001)., Discussion: Among middle-aged adults enrolled in 2 large population studies, poor cardiovascular health profiles were associated with two-fold higher risk of developing a composite outcome that captures the most important diseases related to poor brain health. Because the evaluated risk factors are all modifiable, our findings highlight the potential brain health benefits of using the Life's Essential 8 to guide cardiovascular health optimization.

Abstract: Acquired hemophilia A (AHA) is an autoimmune bleeding disorder that is caused by factor VIII (FVIII) autoantibodies with high morbidity and mortality due to bleeding and complications from immunosuppression (IST). To address the real-world implications of the FVIII mimetic antibody, emicizumab, and the role of IST, we retrospectively collected de-identified data on 62 patients with AHA who were treated off-label with emicizumab for a median of 10 weeks at 12 US-based hemophilia treatment centers. Most patients (95.2%) had acute bleeding at diagnosis, and 62.9% had partial or no control of bleeds despite the use of hemostatic agents at the time emicizumab was started. The main reason for initiating emicizumab was outpatient bleeding prophylaxis. After initiation of emicizumab, 87.1% had no additional bleeds. There were 6 breakthrough bleeds (2 spontaneous) in 5 patients and no fatal bleeding events during maintenance emicizumab treatment. The mean breakthrough bleed rate per patient-week was 0.02 (95% confidence interval, 0.0-0.03) during the first 12 weeks of emicizumab for the 55 patients with at least 12 weeks of follow-up. Of these patients, 92.7% received IST and 74.5% were prescribed rituximab-based regimens. Complete resolution of inhibitor and normalization of FVIII levels occurred in 56% overall and in 63% of the patients treated with rituximab. Overall, the median time to discontinuation of emicizumab and IST was 18 weeks. Two patients had thrombotic events while on emicizumab, but no adverse events were attributed to emicizumab and there were no infections attributed to IST. Emicizumab provides effective outpatient bleeding prophylaxis for AHA, and concurrent IST may further mitigate bleeding., (© 2024 by The American Society of Hematology.

Purpose: The conduct of cancer clinical research in the United States is supported by both private and public sponsors. Industry aims to obtain new drug approvals. Federally-sponsored trials examine a broad set of research questions that are not typically addressed by industry; these trials, which are also more commonly conducted in diverse populations, were recently shown to have contributed to gains of 14 million life-years for patients with cancer. Despite the different mandates, the proportion of patients who might participate in industry-sponsored versus federally-sponsored cancer studies is unknown., Methods: We evaluated trial enrollment patterns from 2008 to 2022 using ClinicalTrials.gov data. The ratio of enrollments attributable to industry versus federal sponsors was estimated. A large set of estimates on the basis of different combinations of study characteristics were generated. Point estimates were determined as the mean of combinations and confidence limits by the IQR. Five-year intervals were examined to smooth annual variation., Results: In total, N = 26,080 studies were examined. The estimated enrollment ratio from 2018 to 2022 for all industry-sponsored versus federally-sponsored trials was 8.1 (IQR, 6.2-9.9). For adult trials, the ratio increased from 4.8 (IQR, 4.4-5.3) during 2008-2012 to 9.6 (IQR, 7.4-11.8) during 2018-2022; for trials in children, the ratio increased from 0.7 (IQR, 0.6-0.7) to 2.3 (IQR, 1.8-2.7). Despite increasing cancer incidence, enrollment counts for federally-sponsored trials were flat over the study period., Conclusion: In the United States, there is a growing reliance on industry to conduct cancer clinical research. Underinvestment in federally-sponsored research comes at a cost for both patients and researchers, with lost opportunities for scientific, clinical, and population advances.

Strategies to bring clinical trials closer to patients gained momentum during the COVID-19 pandemic, enabling more participants to receive treatment and/or testing in their local communities. Incorporation of decentralized trial elements presents both opportunities and challenges, spanning regulatory, technical, and operational aspects. This ASCO research statement includes timely consensus-driven recommendations and a call for engagement of all research stakeholders. ASCO held multistakeholder meetings with leaders in oncology research and concluded that research-related regulatory and administrative requirements and burdens present critical barriers to decentralizing trials. One example is sponsor and contract research organization (CRO) use of US Food and Drug Administration (FDA)'s Statement of Investigator (Form 1572), which was found to exceed FDA's stated intent and used in conservative ways disproportionate to potential risks to participants and scientific integrity. As a result, research sites experience an avalanche of downstream administrative and regulatory activities that consume considerable resources. This statement recommends four key solutions to address such barriers and recalibrate regulatory and administrative expectations for decentralizing trials: (1) FDA should engage the research community in a public-private partnership to modernize standards and enable local access to trials; (2) sponsors and CROs should develop standards and protocols that accommodate flexible approaches, enable local participation, provide clarity around roles and requirements, and promote consistency; (3) research centers, networks, and sites should update policies and procedures to implement decentralized trial elements; and (4) research community should develop a streamlined, uniform mechanism to simplify regulatory data collection and documentation and use it consistently across trials. We can and must prioritize a concerted commitment to simplify and streamline regulatory requirements and practices to broaden access to and participation in cancer clinical trials.

Background: Implementation of evidence-based practice (EBP) in child and adolescent mental health services (CAMHS) is a priority to improve service delivery and outcomes. Clinicians' EBP attitudes are likely to play a crucial role in implementation but are poorly understood. This study aimed to assess variation in EBP attitudes in a large national sample of CAMHS clinicians in Sweden, and to compare these findings to findings from the United States of America (USA)., Methods: CAMHS clinicians (n = 799; 60% response rate) completed the Evidence-Based Practice Attitude Scale (EBPAS) and items from the Organizational Readiness for Change Scale (ORC) ahead of an EBP for depression implementation effort across Sweden. EBPAS scores were compared with the USA study. Predictors of global and specific attitudes (gender, age, working years, education, profession, perceived benefit of diagnosis and organizational readiness and type of service) were examined using simple and multiple linear regressions., Results: Clinicians had positive attitudes towards EBP on the four-dimensional subscales of the EBPAS, somewhat more so than their American counterparts. Clinician and organizational characteristics were related to at least one attitudinal dimension in both models, with perceived utility of diagnosis being the strongest and most consistent predictor across dimensions and models., Conclusions: Results from this large-scale national study underscore the need to consider cultural, contextual, and individual variations in attitudes towards EBP when planning implementation efforts. Such efforts may need to be tailored to the working contexts, needs, and values of CAMHS clinicians, particularly their views on the utility of diagnosis., Competing Interests: Declarations Ethics approval and consent to participate All procedures performed in studies involving human participants were in accordance with the ethical standards of the institutional and/or national research committee and with the 1964 Helsinki declaration and its later amendments or comparable ethical standards.

Background: Adults who maintain ideal cardiovascular health (CVH) profiles up to midlife have lower risk of several chronic diseases and better quality of life. Some evidence suggests that individual-level exposures earlier in life shape midlife CVH, but the impact of neighborhood-level exposures over the life course remains understudied., Methods and Results: Participants were 3017 Black and White men and women aged 18 to 30 years at baseline (1985-1986), recruited from Birmingham, Alabama; Minneapolis, Minnesota; Chicago, Illinois; and Oakland, California, as part of the CARDIA (Coronary Artery Risk Development in Young Adults) study. Measures of the neighborhood food and physical activity environment were linked to participant addresses collected at baseline. CVH was measured on the basis of the American Heart Association's Life's Simple 7 criteria in young adulthood and 30 years later (2015-2016) when participants were midlife (aged 48-60 years). Associations of young adult neighborhood food environment and physical activity resources with midlife CVH (moderate versus high and low versus high) were examined using multinomial logistic regression. Models were adjusted for young adult sociodemographic factors. Participants who lived farther away from a major park in young adulthood were more likely to have low versus high CVH scores (odds ratio, 1.54 [95% CI, 1.22-1.96]) and more likely to have moderate versus high CVH scores (odds ratio, 1.39 [95% CI, 1.12-1.73]) in midlife. No other neighborhood measures were significantly associated with CVH., Conclusions: Young adulthood may be a sensitive period in which having convenient access to physical activity-promoting resources may help them establish healthy habits that can carry into midlife.

Background: Pediatric hypertension is linked to environmental factors like neighborhood noise disrupting sleep, which is crucial for health. The specific interaction between noise and sleep health in causing hypertension still needs to be explored., Methods and Results: We analyzed data from 3320 participants of the ABCD (Adolescent Brain Cognitive Development) study, recruited across 21 US cities and monitored from 2018 to 2020 through 2020 to 2022. Participants with complete data on Fitbit-tracked sleep, blood pressure, height, neighborhood noise, and covariates (biological sex, race and ethnicity, pubertal stage, waist circumference) were included. Hypertension was defined as average blood pressure ≥95th percentile for age, sex, and height. Sleep health was categorized on the basis of daily duration: healthy (9-12 hours), moderately healthy (±1 hour from optimal), and low (≥1 hour deviation). Noise exposure was measured as median nighttime anthropogenic noise levels by zip code. The incidence of hypertension increased from 1.7% (95% CI, 1.4-2.1) in 2018 to 2020 to 2.9% (95% CI, 2.4-3.6) in 2020 to 2022. Adolescents with healthier sleep had a lower risk of developing hypertension (relative risk, 0.63 [95% CI, 0.25-0.82]), while no significant effects were found for neighborhood noise alone or in combination with sleep health., Conclusions: Adequate sleep significantly reduces the risk of hypertension in adolescents, independent of environmental noise exposure. These findings underscore the importance of promoting good sleep hygiene among youth to mitigate hypertension risk.

Background: White matter hyperintensities (WMH) and their progression are associated with risk of dementia and stroke, so are an important target for clinical trials. The cost of broad magnetic resonance imaging (MRI) screening to identify eligible individuals, however, limits the feasibility of designing clinical trials targeting WMH. A low-cost retinal or clinical screening measure before MRI could reduce recruitment costs versus an MRI-only screening design in a hypothetical clinical trial., Methods and Results: Data from the Atherosclerosis Risk in Communities study with valid retinal and WMH measurements ( N =1311) were used. To identify a population at greater likelihood of significant WMH on MRI and thus reduce the number of screening MRIs required, we evaluated 3 theoretical prescreening measures: (1) retinal, (2) clinical, (3) combined clinical-retinal. Given a target sample for clinical trials ( N =646), we calculated screening sample sizes based on the proportion within the population having an elevated score for each prescreening measure (separately) multiplied by the proportion of significant WMH among those with that prescreening feature. Recruitment costs were calculated using estimated retinal and MRI cost estimates. Compared with the estimated cost of MRI-only screening (>$4.24 million, requiring MRI on 6526 participants), prescreening for a high clinical score resulted in total cost of $2.47 million, with an initial screening group of 52 778 participants, with MRI in 3801. A high clinical-retinal score cutoff resulted in costs of $2.9 million while requiring 13 572 participants, with 3801 completing MRI., Conclusions: A 2-stage design with low-cost prescreening measures is a promising approach, resulting in reduced theoretical recruitment costs compared with an MRI-only design.

Background: There is currently limited evidence comparing the association between metabolic dysfunction-associated fatty liver disease (MAFLD), nonalcoholic fatty liver disease (NAFLD), and the risk of peripheral artery disease (PAD). This study aims to analyze the associations of MAFLD and NAFLD with incident PAD., Methods and Results: Two longitudinal studies, the UKB (UK Biobank) study (n=372 216) and the ARIC (Atherosclerosis Risk in Communities) study (n=4681), categorized participants into MAFLD/non-MAFLD groups and NAFLD/non-NAFLD groups. Subsequently, participants were classified into 4 groups: non-fatty liver disease, MAFLD-only, NAFLD-only, and both MAFLD and NAFLD groups. Cox proportional hazard model estimated associations of MAFLD/NAFLD status, subtypes, and liver fibrosis severity with PAD risk. The MAFLD group had a higher risk of incident PAD compared with the non-MAFLD group, and similarly, the NAFLD group had a higher risk compared with the non-NAFLD group. Among these 4 groups, the MAFLD-only group had the strongest association with the risk of incident PAD, while the NAFLD-only group was not independently associated. Diabetic MAFLD subtype was significantly associated with increased PAD risk, and higher level of liver fibrosis scores correlated with elevated PAD risk., Conclusions: Both MAFLD and NAFLD are significantly associated with an increased incidence of PAD, with stronger associations in MAFLD and diabetic MAFLD population. These findings emphasize that the need for screening and prevention strategies for PAD in this high-risk population is warranted. The assessment of MAFLD and its subtypes should be considered as an integral component of cardiovascular risk assessment.

Accurate estimation of the dispersal velocity or speed of evolving organisms is no mean feat. In fact, existing probabilistic models in phylogeography or spatial population genetics generally do not provide an adequate framework to define velocity in a relevant manner. For instance, the very concept of instantaneous speed simply does not exist under one of the most popular approaches that models the evolution of spatial coordinates as Brownian trajectories running along a phylogeny. Here, we introduce a family of models-the so-called Phylogenetic Integrated Velocity (PIV) models-that use Gaussian processes to explicitly model the velocity of evolving lineages instead of focusing on the fluctuation of spatial coordinates over time. We describe the properties of these models and show an increased accuracy of velocity estimates compared to previous approaches. Analyses of West Nile virus data in the United States indicate that PIV models provide sensible predictions of the dispersal of evolving pathogens at a one-year time horizon. These results demonstrate the feasibility and relevance of predictive phylogeography in monitoring epidemics in time and space., Competing Interests: Competing interests statement:The authors declare no competing interest.

The ethnoracial future of the United States has been framed as a demographic binary: Whites vs. people of color. The argument here is that this binary distorts by failing to take into adequate account the rapidly growing group of Americans who have been raised in mixed minority and White families, the great majority of the total mixed population. The members of this group generally have distinctive social characteristics: socioeconomic advantages compared to minorities and social integration into milieus with many Whites, as revealed by relatively high rates of marriage to them. However, their identities often encompass their minority heritage. Accordingly, they straddle the society's major ethnoracial fracture line, creating an in-between social space and connecting, through kinship and other close social relations, both of its sides. However, their numbers are distorted in public national population data, such as census data and population projections; and they are typically counted as part of the non-White population.

Attention to social justice is essential to improving cardiovascular health outcomes. In the absence of social justice, equitable cardiovascular health is impossible. This viewpoint provides a brief synopsis of the 2023 Journal of the American Heart Association (JAHA) -sponsored session titled "Moving Towards Social Justice in Cardiovascular Health." We define social justice and summarize the burden of cardiovascular disease inequity in the United States. We also highlight strategies for achieving social justice, including addressing workforce diversity, integrating social determinants into cardiovascular research, designing cardiovascular interventions to close the equity gap, and improving inclusivity in cardiovascular disease trials.

Background: Work-related stress is a psychosocial risk factor linked to a higher risk of cardiovascular disease. However, the association between work-related stress and cardiovascular health (CVH) is not well established. We estimated the association between work-related stress and CVH in a multiethnic sample of adults free of cardiovascular disease at baseline., Methods and Results: We performed a cross-sectional analysis of 3579 community-based men and women, aged 45 to 84 years, of the Multi-Ethnic Study of Atherosclerosis from data collected between 2000 and 2002. Work-related stress (yes/no) was assessed by a self-administered questionnaire. CVH was measured by the American Heart Association's Life's Simple 7 metrics (smoking, physical activity, body mass index, diet, total cholesterol, blood pressure, and blood glucose). Each metric contributed 0, 1, or 2 points if in the poor, intermediate, or ideal range, respectively. The aggregated CVH score was 0 to 14 points and categorized as inadequate (0-8 points), average (9-10 points), and optimal (11-14 points). Polytomous logistic regression was used to estimate the association between work-related stress and CVH, adjusting for sociodemographic factors. The mean±SD age was 57±8 years, and 48% were women. Work-related stress was reported by 20% of participants. In fully adjusted models, participants with work-related stress had lower odds of having average (adjusted odds ratio [OR], 0.75 [95% CI, 0.62-0.92]) and optimal (adjusted OR, 0.73 [95% CI, 0.58-0.92]) CVH scores compared with participants without work-related stress., Conclusions: Work-related stress was associated with unfavorable CVH. These findings underscore the importance of workplace psychological well-being and suggest the need for studies on interventions that may reduce work-related stress and promote CVH.

Background: Seven million lesbian, gay, and bisexual (LGB) adults will be aged >50 years by 2030; assessing and addressing their risk for cardiovascular disease is critical., Methods and Results: We analyzed a nationwide cohort using the Veterans Health Administration data. Sexual orientation (SO) was classified via a validated natural language processing algorithm. Prevalent atherosclerotic cardiovascular disease (ASCVD) (history of acute myocardial infarction, ischemic stroke, or revascularization) was identified via International Classification of Diseases, Ninth and Tenth Revision ( ICD-9 and ICD-10 ) codes. The index date was the date of the first primary care appointment on or after October 1, 2009. We ascertained covariates and prevalent ASCVD in the year following the index date; the baseline date was 1 year after the index date. We calculated sample statistics by sex and SO and used logistic regression analyses to assess associations between SO and prevalent ASCVD. Of 1 102 193 veterans with natural language processing-defined SO data, 170 861 were classified as LGB. Prevalent ASCVD was present among 25 031 (4105 LGB). Adjusting for age, sex, race, and Hispanic ethnicity, LGB veterans had 1.24 [1.19-1.28] greater odds of prevalent ASCVD versus non-LGB identified veterans. This association remained significant upon additional adjustment for the ASCVD risk factors substance use, anxiety, and depression (odds ratio [OR],1.17 [95% CI, 1.13-1.21]). Among a subset with self-reported SO, findings were consistent (OR, 1.53 [95% CI, 1.20-1.95])., Conclusions: This is one of the first studies to examine cardiovascular risk factors and disease of the veteran population stratified by natural language processing-defined SO. Future research must explore psychological, behavioral, and physiological mechanisms that result in poorer cardiovascular health among LGB veterans.

Background: The association between nonalcoholic fatty liver disease and cardiovascular disease is firmly established, yet the association between noninvasive liver fibrosis scores and cardiovascular events remains a topic of uncertainty. Our study aimed to explore the association between liver fibrosis and heart failure., Methods and Results: The data set was from the National Health and Nutrition Examination Survey 2011 to 2018. Advanced hepatic fibrosis risk was assessed through 3 noninvasive liver fibrosis scores: Fibrosis-4 score (FIB-4), the nonalcoholic fatty liver disease fibrosis score (NFS), and the aspartate aminotransferase to platelet ratio index (APRI). We included 19 695 eligible participants. The national prevalence of advanced liver fibrosis risk in the United States was 4.20%, 8.06%, and 0.35% as determined by FIB-4, NFS, and APRI scores, respectively. Weighted logistic regression analysis revealed significant associations between advanced liver fibrosis risk and the prevalence of heart failure (continuous variables, FIB-4: odds ratio [OR], 1.15 [95% CI, 1.07-1.23]; NFS: OR, 1.42 [95% CI, 1.23-1.64]; APRI: OR, 1.44 [95% CI, 1.15-1.81]). When the scores were assessed as categorical variables, the results were still significant (FIB-4 ≥2.67 versus FIB-4 <1.3: OR, 2.18 [95% CI, 1.47-3.24]; NFS ≥0.675 versus NFS <-1.455: OR, 2.53 [95% CI, 1.37-4.68]). Subgroup analysis found that the association between APRI and heart failure was stronger in female patients., Conclusions: In the general US population, the prevalence of advanced liver fibrosis risk varied between 0.35% and 8.06% as indicated by noninvasive liver fibrosis scores. FIB-4, NFS, and APRI scores were linked to an elevated prevalence of heart failure.

Cardiac arrhythmias are commonly noted in patients during infections with and recovery from COVID-19. Arrhythmic manifestations span the spectrum of innocuous and benign to life-threatening and deadly. Various pathophysiological mechanisms have been proposed. Debate continues on the impact of incident and exacerbated arrhythmias on the acute and chronic (recovery) phase of the illness. COVID-19 and COVID-19 vaccine-associated myocardial inflammation and autonomic disruption remain concerns. As the pandemic has transformed to an endemic, with discovery of new SARS-CoV-2 variants, updated vaccines, and potent antiviral drugs, vigilance for COVID-19-associated arrhythmic and dysautonomic manifestations remains. The objective of this American Heart Association scientific statement is to review the available evidence on the epidemiology, pathophysiology, clinical presentation, and management of cardiac arrhythmias and autonomic dysfunction in patients infected with and recovering from COVID-19 and to provide evidence-based guidance. The writing committee's consensus on implications for clinical practice, gaps in knowledge, and directions for future research are highlighted.

This study aims to evaluate the association between the Weight-Adjusted Waist Index (WWI) and osteoarthritis (OA) utilizing cross-sectional data from the 2005-2014 National Health and Nutrition Examination Survey (NHANES). The study analyzed data from 12,696 participants across the 2005-2014 NHANES cycles to examine differences in demographic, socioeconomic, lifestyle, and health-related variables across WWI quartiles. Multivariable logistic regression models were employed to assess the relationship between WWI and the risk of OA. Receiver Operating Characteristic (ROC) curve analysis was conducted to evaluate and compare the predictive ability of WWI, BMI, waist circumference, and weight in identifying OA risk. Scatter plots were generated to visualize the association between WWI and OA, with linear regression lines illustrating trends and statistical significance. Restricted cubic spline (RCS) analysis was used to further explore the nonlinear relationship between WWI and OA risk. Forest plots were used to display the impact of WWI on OA risk across subgroups such as gender, age, and race, showing that individuals with higher WWI generally exhibit a significantly increased risk of OA. After adjusting for multiple covariates, the findings indicated a significant association between higher WWI and an increased risk of OA. Subgroup analyses, including gender, age, and race, further reinforced the consistent association between WWI and OA risk. In the U.S. adult population, an elevated WWI is significantly associated with an increased risk of OA, suggesting that WWI could serve as a potential indicator for assessing OA risk., Competing Interests: Declarations Competing interests The authors declare no competing interests., (© 2024.

Background and Objectives: Prediabetes is a high-risk state for diabetes. We aimed to illustrate secular trends in the Children's Dietary Inflammation Index (C-DII) among U.S. adolescents and assess its association with prediabetes., Methods: Adolescents aged 12-18 years were collected from the National Health and Nutrition Examination Survey, 2001-2018. Prediabetes was defined based on Hemoglobin A1c, fasting glucose, and glucose tolerance levels. Risk was quantified by odds ratio (OR) and 95% confidence interval (CI)., Results: A total of 13,684 adolescents were analyzed, representing a weighted total population of 33,351,181. C-DII scores declined significantly from 2001 to 2012 and increased from 2013 to 2018. The relationship between C-DII and prediabetes was roughly linear. When assigning the low C-DII scores as the reference, adolescents with medium and high C-DII scores were 1.22 (adjusted 95% CI: 1.04-1.44) and 1.25 (0.99-1.60) times more likely to have prediabetes. In subgroup analyses, the risk for prediabetes was significantly enhanced in boys (adjusted OR = 1.26 and 1.45 for medium and high C-DII scores, 95% CI: 1.05-1.51 and 1.09-1.92), and in adolescents living in poor families for medium (1.34 and 1.44, 1.08-1.67 and 1.07-1.95)., Conclusions: Our findings indicate a V-shaped secular trend in C-DII scores from 2001 to 2018 in U.S. adolescents, with the nadir in 2011-2012, and the risk for prediabetes was significantly increased by over 20% in adolescents possessing medium or high C-DII scores., Competing Interests: Competing interests The authors declare no competing interests.

Physical activity (PA) has a well-documented, positive effect on overall health and wellbeing. Additionally, addressing activity-friendly infrastructure in communities can promote PA in everyday life. A universal design (UD) lens on PA promotes accessibility to the broadest audience and contributes to equal benefit of increased PA. This study explores the intersectionality of age, gender, and disability in United States-based gender minority adults using multiple regression analysis. A statistically significant relationship emerged between participants' (n = 125) disability status and their corresponding perceptions of accessible design in their communities. However, gender, age, and PA did not have statistical significance in the regression model. The results reported in this paper are specific to the unique challenges these populations face in accessing inclusive and accessible community environments. Few health disparities studies have combined multiple elements of one's identity with measurements of PA to examine environmental perceptions among multiply marginalized communities. This research seeks to address this research gap.

Across two studies, we examined intergroup relations between Black-White multiracial and Black monoracial people in the U.S. Study 1 showed that Black-White multiracial participants reported more solidarity with Black than White people, but less solidarity with Black people than Black participants reported. Likewise, their race-relevant political attitudes were somewhat more aligned with Black than White participants, but not completely aligned with Black participants. Reflecting this pattern, Black participants perceived that Black-White multiracial people feel more solidarity with Black than White people, but less solidarity with Black people than they themselves feel. Solidarity perceptions were consequential. Both Study 1 (correlational) and Study 2 (experimental) showed that Black participants' perceptions of Black-White multiracial people's solidarity with Black people were related to their inclusion of multiracial people. Furthermore, contingent on high levels of solidarity with Black people, multiracial people's relationships with White people were less consequential for Black participants' inclusion of them., Competing Interests: Competing interests The authors declare no competing interests., (© 2024.

Avatrombopag is a next-generation thrombopoietin receptor agonist approved for the treatment of thrombocytopenia in patients with chronic liver disease scheduled to undergo surgery and thrombocytopenia in patients with chronic immune thrombocytopenia. However, realistic data on its post-marketing long-term safety and tolerability in large sample populations are incomplete. The adverse event (AE) reports of avatrombopag were analyzed based on the FAERS database. By extracting large-scale data from the FAERS database, this study used various signal quantification techniques such as reporting odds ratios, proportional reporting ratios, Bayesian confidence propagation neural network, and multi-item gamma Poisson shrinker to calculate and evaluate the ratio and association between avatrombopag and specific AEs. In the FAERS database, data from the second quarter of 2018 to the fourth quarter of 2023 were extracted for this study, a total of 1217 avatrombopag-related AEs reports were included for analysis. Based on four calculation methods, this study identified and 32 preferred terms associated with avatrombopag. Common AEs in the product label such as thrombosis, headache, contusion, petechiae, and gingival bleeding were detected. AEs not mentioned in the product label, such as photopsia and ear discomfort were also detected. The first 30 days after initiation of medication were the most common period for both serious and non-serious AEs. This study demonstrates the common AEs and the potential AEs associated with avatrombopag in real-world practice, which could provide valuable cautionary evidence for clinicians and pharmacists to manage safety issues with avatrombopag., Competing Interests: Competing interests  The authors declare no competing interests.

Wastewater-Based Epidemiology (WBE) has become a powerful tool for assessing disease occurrence in communities. This study investigates the coronavirus disease 2019 (COVID-19) epidemic in the United States during 2023-2024 using wastewater data from 189 wastewater treatment plants in 40 states and the District of Columbia. Severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) and pepper-mild mottle virus normalized SARS-CoV-2 RNA concentration data were compared with COVID-19 hospitalization admission data at both national and state levels. We further investigate temporal features in wastewater viral RNA abundance, with peak timing and cross-correlation lag analyses indicating that wastewater SARS-CoV-2 RNA concentrations precede hospitalization admissions by 2 to 12 days. Lastly, we demonstrate that wastewater treatment plant size has a significant effect on the variability of measured SARS-CoV-2 RNA concentrations. This study highlights the effectiveness of WBE as a non-invasive, timely and resource-efficient disease monitoring strategy, especially in the context of declining COVID-19 clinical reporting., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Schenk et al.

Background: Researchers have increasingly recognized the importance of structural and social determinants of health (SSDOH) as key drivers of a multitude of diseases and health outcomes. The Multi-Ethnic Study of Atherosclerosis (MESA) is an ongoing, longitudinal cohort study of subclinical cardiovascular disease (CVD) that has followed geographically and racially/ethnically diverse participants starting in 2000. Since its inception, MESA has incorporated numerous SSDOH assessments and instruments to study in relation to CVD and aging outcomes. In this paper, we describe the SSDOH data available in MESA, systematically review published papers using MESA that were focused on SSDOH and provide a roadmap for future SSDOH-related studies., Methods and Findings: The study team reviewed all published papers using MESA data (n = 2,125) through January 23, 2023. Two individuals systematically reviewed titles, abstracts, and full text to determine the final number of papers (n = 431) that focused on at least one SSDOH variable as an exposure, outcome, or stratifying/effect modifier variable of main interest (discrepancies resolved by a third individual). Fifty-seven percent of the papers focused on racialized/ethnic groups or other macrosocial/structural factors (e.g., segregation), 16% focused on individual-level inequalities (e.g. income), 14% focused on the built environment (e.g., walking destinations), 10% focused on social context (e.g., neighborhood socioeconomic status), 34% focused on stressors (e.g., discrimination, air pollution), and 4% focused on social support/integration (e.g., social participation). Forty-seven (11%) of the papers combined MESA with other cohorts for cross-cohort comparisons and replication/validation (e.g., validating algorithms)., Conclusions: Overall, MESA has made significant contributions to the field and the published literature, with 20% of its published papers focused on SSDOH. Future SSDOH studies using MESA would benefit by using recently added instruments/data (e.g., early life educational quality), linking SSDOH to biomarkers to determine underlying causal mechanisms linking SSDOH to CVD and aging outcomes, and by focusing on intersectionality, understudied SSDOH (i.e., social support, social context), and understudied outcomes in relation to SSDOH (i.e., sleep, respiratory health, cognition/dementia)., Competing Interests: The authors have declared that no competing interests exist., (Copyright: © 2024 Besser et al.

Cardiometabolic index (CMI) is a novel anthropometric metric that integrates lipid and adiposity characteristics. The correlation between periodontitis development and CMI is ambiguous. The objective of this study was to establish the association between CMI and periodontitis by analyzing data from the NHANES (National Health and Nutrition Examination Survey) database. A cross-sectional study was conducted on a cohort of 6188 people selected from the NHANES database, covering the period from 2009 to 2014. The study employed multivariate logistic regression to examine the independent correlation between CMI and periodontitis. Subgroup data were analyzed and interaction tests were conducted to assess the impact of variables on the correlation between CMI and periodontitis. The CMI index was significantly and positively associated with the presence of periodontitis (β = 0.03, 95%CI(0.01, 0.05), p = 0.0092). In addition, a U-shaped relationship was found between CMI index and periodontitis severity in an older American population (65 < = age < = 80, with a folding point of 1.44, p = 0.008). This study demonstrates a significant correlation between CMI and periodontitis, positioning CMI as a crucial indicator for assessing periodontal health. Future efforts should prioritize oral hygiene interventions for patients with elevated CMI levels to facilitate early intervention and enhance overall health outcomes., Competing Interests: Declarations Competing interests The authors declare no competing interests., (© 2024.

Purpose: The impact of the components of survivorship care plans on adherence to cancer screening guidelines among cancer survivors is limited. We examined the association of receipt of treatment summaries, follow-up instructions, and type of doctor providing survivorship care with adherence to breast cancer screening (BCS) and cervical cancer screening (CCS) guidelines in female cancer survivors., Methods: A cross-sectional analysis using Behavioral Risk Factor Surveillance System (BRFSS) data from 2014, 2016 and 2018 was conducted. BCS and CCS-eligible women were aged 40-74 and 30-64, respectively. BCS adherence was defined as a mammogram within 2 years and CCS adherence as a pap smear within 3 years or HPV test within 5 years. Univariate analysis with chi-square and multivariable logistic regression are reported., Results: 5,001 BCS and 3,014 CCS-eligible survivors were identified. In the BCS group, recipients of treatment summaries and follow-up instructions were significantly more adherent with BCS (84.1% vs. 77.4%; 83.4% vs. 74%, respectively, p < 0.001). In the CCS group, recipients of follow-up instructions were significantly more adherent with CCS (78.1% vs. 67.7%, p < 0.001). In both groups, there was no significant difference in BCS or CCS based on type of physician providing care (p = 0.087). On multivariate analysis, receipt of follow-up instructions was the only factor significantly associated with BCS (OR:2.81; 95%CI:1.76-4.49) and CCS (OR:3.14; 95%CI:1.88-5.23)., Conclusions: Follow-up instructions, as part of survivorship care plans, have the strongest association with BCS and CCS among female cancer survivors. Additional research should focus on improving the distribution of survivorship care plans, particularly follow-up instructions, as a method to increase BCS and CCS among cancer survivors., Competing Interests: Declarations Ethics approval This is an observational study with publicly available de-identified individual data and did not require approval from the Rutgers University Institutional Board Review.

Background: Clinical management of patients with chronic cardiometabolic disease is complicated by polypharmacy. Consequently, when patients clinically deteriorate, physicians are challenged to distinguish both medication nonadherence and drug-drug interactions (DDI) from chronic disease progression., Methods: In this randomized controlled trial, we enrolled U.S. board-certified Primary Care Physicians (PCPs) serving patients with cardiometabolic disease. PCPs were randomized and managed their patients with (intervention), or without (control), a novel chronic disease management test (CDMT) that can detect medication nonadherence and DDIs. Patients' medical records were abstracted at baseline and 3-month follow-up. Primary outcomes were the CDMT's impact on both the PCPs' detection of medication nonadherence and DDI, and the frequency of performing medication nonadherence- and DDI-related clinical actions. Secondary outcomes examined the types of clinical actions performed. Primary and secondary outcomes were analyzed by logistic regression using single variable and clustered multivariable modeling to adjust for similarities in patient characteristics, by PCP practice., Results: Sixteen intervention and 20 control PCPs shared de-identified records for 126 and 207 patients, respectively. There were no significant demographic differences between the two study arms, among PCPs or patients. At baseline, there was no significant difference between the intervention and control PCPs in the percentage of clinical actions performed for medication nonadherence (P = 0.98) and DDI (P = 0.41). At 3-month follow-up (after CDMT), 69.1% of intervention compared to 20.3% of control patients with medication nonadherence had a related clinical action performed (P < 0.001). Regarding DDI, 37.3% of intervention compared to 0.5% of control patients had a relevant clinical action performed in follow-up (P < 0.001). Across the range of medication nonadherence- and DDI-related actions, the intervention compared to the control PCPs were more likely to adjust the medication regimen (24.1% vs. 9.5%) and document medication nonadherence in the patient chart (31.0% vs. 14.3%) at follow-up (P = 0.04)., Conclusions: Although intervention and control PCPs similarly detected and acted upon medication nonadherence and DDI at baseline, intervention PCPs' detection increased significantly after using the CDMT. Also, the clinical actions performed with CDMT support were more clinically rigorous. These outcomes support the clinical utility of CDMT in the management of symptomatic patients with cardiometabolic disease and polypharmacy., Trial Registration: https://clinicaltrials.gov/study/NCT05910684 ., Competing Interests: Declarations Ethics approval and consent to participate This study was conducted in accordance with ethical standards and approved on 19 October 2021 by the Advarra Institutional Review Board (IRB; Columbia, MD, USA).

Background: Social media has become a vital tool for health care providers to quickly share information. However, its lack of content curation and expertise poses risks of misinformation and premature dissemination of unvalidated data, potentially leading to widespread harmful effects due to the rapid and large-scale spread of incorrect information., Objective: We aim to determine whether social media had an undue association with the prescribing behavior of hydroxychloroquine, using the COVID-19 pandemic as the setting., Methods: In this retrospective study, we gathered the use of hydroxychloroquine in 48 hospitals in the United States between January and December 2020. Social media data from X/Twitter was collected using Brandwatch, a commercial aggregator with access to X/Twitter's data, and focused on mentions of "hydroxychloroquine" and "Plaquenil." Tweets were categorized by sentiment (positive, negative, or neutral) using Brandwatch's sentiment analysis tool, with results classified by date. Hydroxychloroquine prescription data from the National COVID Cohort Collaborative for 2020 was used. Granger causality and linear regression models were used to examine relationships between X/Twitter mentions and prescription trends, using optimum time lags determined via vector auto-regression., Results: A total of 581,748 patients with confirmed COVID-19 were identified. The median daily number of positive COVID-19 cases was 1318.5 (IQR 1005.75-1940.3). Before the first confirmed COVID-19 case, hydroxychloroquine was prescribed at a median rate of 559 (IQR 339.25-728.25) new prescriptions per day. A day-of-the-week effect was noted in both prescriptions and case counts. During the pandemic in 2020, hydroxychloroquine prescriptions increased significantly, with a median of 685.5 (IQR 459.75-897.25) per day, representing a 22.6% rise from baseline. The peak occurred on April 2, 2020, with 3411 prescriptions, a 397.6% increase. Hydroxychloroquine mentions on X/Twitter peaked at 254,770 per day on April 5, 2020, compared to a baseline of 9124 mentions per day before January 21, 2020. During this study's period, 3,823,595 total tweets were recorded, with 10.09% (n=386,115) positive, 37.87% (n=1,448,030) negative, and 52.03% (n=1,989,450) neutral sentiments. A 1-day lag was identified as the optimal time for causal association between tweets and hydroxychloroquine prescriptions. Univariate analysis showed significant associations across all sentiment types, with the largest impact from positive tweets. Multivariate analysis revealed only neutral and negative tweets significantly affected next-day prescription rates., Conclusions: During the first year of the COVID-19 pandemic, there was a significant association between X/Twitter mentions and the number of prescriptions of hydroxychloroquine. This study showed that X/Twitter has an association with the prescribing behavior of hydroxychloroquine. Clinicians need to be vigilant about their potential unconscious exposure to social media as a source of medical knowledge, and health systems and organizations need to be more diligent in identifying expertise, source, and quality of evidence when shared on social media platforms., (©Scott A Helgeson, Rohan M Mudgalkar, Keith A Jacobs, Augustine S Lee, Devang Sanghavi, Pablo Moreno Franco, Ian S Brooks, National COVID Cohort Collaborative (N3C).

Background: Per- and polyfluoroalkyl substances (PFAS) are commonly utilized in consumer products. While earlier studies have suggested potential impacts of certain PFAS on serum concentrations of vitamin D, these investigations were constrained to a limited set of conventional PFAS. Moreover, they did not specifically focus on populations with longer duration of PFAS exposure and potentially higher blood PFAS levels, such as older adults, and lacked adequate evidence to examine sex-related disparities., Methods: This observational investigation utilized cross-sectional data obtained from the U.S. NHANES spanning the years 2003 to 2018. Survey-weighted multiple regression models were employed to evaluate the relationship between PFAS exposure and vitamin D concentrations. Multi-pollutant models were employed to evaluate the association between PFAS mixtures and vitamin D concentrations. Subsequently, environmental risk scores (ERS) were constructed to gauge associations with vitamin D concentrations. ERS was computed through a weighted linear combination of PFAS, utilizing calculations from ridge regression and adaptive elasticity network (adENET) methodologies. All analyses were stratified by sex., Results: The study encompassed 3,853 older adults. Our analysis revealed a negative association between PFOA, PFOS, PFNA, and MeFOSAA and serum vitamin D concentrations. In analyses examining mixed exposures, various models consistently indicated an inverse association between PFAS mixed exposure and vitamin D concentrations. Moreover, an increase in ERS of PFAS across the interquartile range was associated with a decrease in vitamin D concentrations (Q4 vs. Q1, adENET: β: -0.083, 95% CI: -0.117, -0.048; ridge regression: β: -0.077, 95% CI: -0.111, -0.042). Notably, these associations were exclusively observed within the female population., Conclusions: Our study indicates that heightened exposure to PFAS correlates with diminished serum vitamin D concentrations in females aged 60 years and older, evident in both single and mixed exposures. These findings find support in in vitro mechanistic studies, suggesting that PFAS may impact the metabolism of 25(OH)D, consequently affecting vitamin D concentrations., Competing Interests: Declarations Ethics approval and consent to participate Not applicable.

Purpose: The objective is to investigate trends in cases of motor vehicle accident-associated (MVA-associated) ocular trauma in which the patient was the driver of the motor vehicle., Methods: The study utilizes data from the 2007-2014 National Trauma Databank (NTDB), a national trauma registry. Status as the driver of the motor vehicle was identified using E-Codes from the International Classification of Diseases, Ninth Revision, Clinical Modification (ICD-9-CM). Trauma diagnoses were identified using D-Codes from the ICD-9-CM. Statistics were performed using IBM SPSS Version 23., Results: We identified 49,660 cases of ocular trauma secondary to an MVA with a 25.3% increase in injuries over the 8-year time period. Men comprised 68.6% (34,057) of cases. Orbital floor fractures (OFFs) were the most commonly observed ocular injury, occurring in 17,647 (35.5%) cases. There were 2,787 cases of open globe injury (OGI) with the highest proportion of cases in the 65 + age group (6.5%). OGIs were seen in 3.0% of cases with OFFs vs. 7.1% in those without. Drivers under 18 were more likely to have optic pathway/cranial nerve injuries (4.4%) and ocular/adnexal contusions (41.2%) than adult drivers. The mortality rate was 4.3% and was highest in the 65 + age group (9.4%)., Conclusion: Men and young adults comprised the majority of cases of MVA-associated ocular trauma. OFFs were seen in approximately one-third of cases of ocular trauma. OGIs were less commonly observed when a concurrent OFF was observed.

Background: Despite advancements in cystic fibrosis (CF) therapeutics, the persistence of chronic infections necessitates continued use of nebulized therapies. Though the Cystic Fibrosis Foundation recommends well-defined cleaning and disinfection of nebulizers to mitigate pathogen exposure risks, discrepancies between Cystic Fibrosis Foundation guidelines, manufacturers' instructions, and variability in center recommendations contribute to confusion and non-standardized practices., Methods: A digital survey was distributed to directors, associate directors, and care coordinators of CF centers across the United States to investigate the methods, frequency, and educational practices surrounding nebulizer care they provide patients. Responses were analyzed using descriptive techniques and chi-square analyses., Results: Of 855 distributed surveys, 129 respondents provided insights into nebulizer care recommendations. Discrepancies in disinfection frequency were notable, with 18% of respondents recommending disinfecting nebulizers less than daily. Approximately 20% of respondents were unsure if their recommendations aligned with Cystic Fibrosis Foundation guidelines while 73% reported that their recommendations strictly adhered to the published guidelines. Of this 73%, all recommended at least daily cleaning, with 69% specifying cleaning before reuse; and 88% recommended disinfection at least daily, with 36% specifying disinfection before reuse. Only 10% recommended both cleaning and disinfection after every use. Disinfection less than daily was recommended by 11% of the respondents who felt they were strictly following the guidelines. We also highlight respondents who cited barriers to strict adhesion to the published guidelines., Conclusions: The highlighted variations in CF centers' recommendations for nebulizer care with deviations from Cystic Fibrosis Foundation guidelines underscore the necessity for developing clear and practical guidelines that consider both efficacy and the realities of patient adherence. Collaboration among CF care centers, patients, guideline committees, and other stakeholders is essential to develop recommendations that effectively address the challenges faced by the CF community, ensuring the safe and effective nebulizer use., Competing Interests: The authors have disclosed no conflicts of interest., (Copyright © 2024 by Daedalus Enterprises.)

Context: Aging increases fracture risk through bone loss and microarchitecture deterioration due to an age-related imbalance in bone resorption and formation during bone remodeling., Objective: We examined the associations between levels of phosphate, calcium (Ca), and alkaline phosphatase (ALP), and fracture risk in initially healthy older individuals., Methods: A post hoc analysis of the Aspirin in Reducing Events in the Elderly (ASPREE) trial recruited 16 703 Australian participants aged 70 years and older and 2411 US participants aged 65 years and older. Analyses were conducted on ASPREE-Fracture substudy participants from Australia with serum calcium, phosphate, and ALP measurement. Fracture data were collected post randomization. Cox regression was used to calculate hazard ratios (HRs) and 95% CIs. Phosphate, Ca, and ALP were analyzed in deciles (D1-D10), with deciles 4 to 7 (31%-70%) as the reference category. Restricted cubic spline curves were used to identify nonlinear associations., Results: Of the 9915 participants, 907 (9.2%) individuals had incident fractures recorded over 3.9 (SD 1.4) years. In the fully adjusted model, men in the top decile (D10) of phosphate had a 78% higher risk of incident fracture (HR 1.78; 95% CI, 1.25-2.54). No such association was observed for women (HR 1.09; 95% CI, 0.83-1.44). The population attributable fraction in men within the D10 phosphate category is 6.9%., Conclusion: This result confirms that high-normal serum phosphate levels are associated with increased fracture risk in older men., (© The Author(s) 2024.

Objectives: Specific to sexual health, individuals in need of information may be adolescents who have limited ability to formally access healthcare. These digital natives may turn to ChatGPT to address their concerns on sexually transmitted infections (STI). We sought to evaluate the veracity of ChatGPT's responses to commonly asked questions on STIs., Methods: We instructed ChatGPT (GPT 3.5) to answer STI questions from three domains, namely, (1) general risk factors for STIs, (2) access to care and diagnosis of STIs and (3) management of STIs and postexposure prophylaxis. The responses were recorded and checked against the US Centers for Disease Control and Prevention STI Treatment Guidelines 2021., Results: Overall, the responses were concise and accurate. In terms of prevention, ChatGPT could also recommend measures like safe sex practices and human papillomavirus vaccination. However, it failed to recommend HIV pre-exposure prophylaxis. When an individual expressed a symptom that could potentially represent STI (eg, dyspareunia) ChatGPT appropriately provided reassurance that other possibilities exist, but advocated for testing. In terms of treatment, ChatGPT consistently communicated the importance of partner testing and follow-up testing, but at times, failed to highlight the importance of testing for other STIs. Overall, the advice given was not tailored to the specific individual's circumstances., Conclusions: ChatGPT can provide helpful information regarding STIs, but the advice lacks specificity and requires a human physician to fine-tune. Its ubiquity may make it a useful adjunct to sexual health clinics, to improve knowledge and access to care., Competing Interests: Competing interests: None declared., (© Author(s) (or their employer(s)) 2024.

Context: Neurofilament light chains (sNFLs) increase in patients with diabetes (DM) and are associated with death., Objective: This work aimed to examine whether sNFL mediates associations of DM with all-cause mortality and the extent of interaction or joint relations of sNFL and DM with mortality., Methods: This population-based cohort study was conducted using the 2013 to 2014 cycle of the National Health and Nutrition Examination Survey. A total of 2071 adults aged 20 to 75 years with sNFL measurements were included. sNFL was lg-transformed (LgNfl). Participants were included whose LgNfl was higher than 1.48 pg/mL or who were diagnosed with DM. All-cause mortality was the primary outcome obtained through linkage to registries., Results: During a median follow-up of 6.1years, 85 participants died. Incidence rates (per 1000 person-years [95% CI]) of all-cause mortality were 27.78 (19.98∼35.58) in adults with LgNfl greater than 1.48 pg/mL and DM, 9.01 (1.99∼16.03) in adults with LgNfl greater than 1.48 pg/mL but no DM, 3.07 (1.01∼5.13) in adults with DM and LgNfl less than or equal to 1.48 pg/mL, and 2.21 (1.15∼3.27) in adults without DM and LgNfl less than or equal to 1.48 pg/mL. Significant interaction but not mediation was observed between LgNfl and DM. Compared with adults without DM and LgNfl less than or equal to 1.48 pg/mL, those with DM and LgNfl greater than 1.48 pg/mL had higher risks of all-cause mortality (hazard ratio; 95% CI, 7.06; 3.52∼14.16)., Conclusion: In general US adults with DM, elevated sNFLs were associated with higher all-cause mortality specifically, supporting an important role of sNFLs in predicting health outcome in individuals with DM., (© The Author(s) 2024.

Context: The association between magnesium status and metabolic syndrome (MetS) remains unclear., Objective: This study aimed to examine the relationship between kidney reabsorption-related magnesium depletion score (MDS) and MetS among US adults., Methods: We analyzed data from 15 565 adults participating in the National Health and Nutrition Examination Survey (NHANES) 2003 to 2018. MetS was defined according to the National Cholesterol Education Program's Adult Treatment Panel III report. The MDS is a scoring system developed to predict the status of magnesium deficiency that fully considers the pathophysiological factors influencing the kidneys' reabsorption capability. Weighted univariate and multivariable logistic regression were used to assess the association between MDS and MetS. Restricted cubic spline (RCS) analysis was conducted to characterize dose-response relationships. Stratified analyses by sociodemographic and lifestyle factors were also performed., Results: In both univariate and multivariable analyses, higher MDS was significantly associated with increased odds of MetS. Each unit increase in MDS was associated with approximately a 30% higher risk for MetS, even after adjusting for confounding factors (odds ratio 1.31; 95% CI, 1.17-1.45). RCS graphs depicted a linear dose-response relationship across the MDS range. This positive correlation remained consistent across various population subgroups and exhibited no significant interaction by age, sex, race, adiposity, smoking status, or alcohol consumption., Conclusion: Higher urinary magnesium loss as quantified by MDS may be an independent linear risk factor for MetS in US adults, irrespective of sociodemographic and behavioral factors. Optimizing magnesium nutritional status could potentially confer benefits to patients with MetS., (© The Author(s) 2024. Published by Oxford University Press on behalf of the Endocrine Society.)

BACKGROUND Amyotrophic lateral sclerosis (ALS) is a motor neuron disease that leads to rapid degeneration of nerves in the brain and spinal cord, with eventual loss of voluntary movements, including breathing. This retrospective study of medical record data from 105 US veterans diagnosed with ALS at the Oklahoma City VA Medical Center between 2010 and 2021 aimed to identify patient demographics, and the causes and places of death for these veterans. MATERIAL AND METHODS Data from 105 US veterans diagnosed with ALS by the El Escorial criteria and supported by neurophysiology testing was reviewed. The information about the place and cause of death was obtained from each patient's care provider and death certificate. Crude mortality rates (per 100 person-years) and standardized mortality ratios (SMRs) were calculated for the causes of death, by sex, age group, and location of death. RESULTS During the 11-year follow-up period, 80 (76.2%) veterans with ALS died. The mean (SD) follow-up time was 4.53 (4.55) years. Most of the deaths were due to respiratory failure and pneumonia (n=43, mortality rate=9.21 per 100 person-years). Most patients died at home (n=71, 88.7%). The annual crude mortality rate was 16.7 and the all-cause death SMR was 25.63 (95% CI, 20.32-31.55). CONCLUSIONS This study's findings are that in veterans with ALS, the main cause of death is respiratory disease (failure). The main location of death was the home, with their family members. The all-cause mortality rate among veterans with ALS was 26 times greater than for the general Oklahoma population.

Purpose: Patients with alpha-1 antitrypsin deficiency (AATD) often experience substantial delays from the onset of symptoms to a diagnosis. We explored the impact of delayed diagnosis of AATD on healthcare costs and utilization by assessing costs/utilization before and after diagnosis., Methods: Retrospective claims data was used to conduct a longitudinal analysis of a cohort of patients with follow-up over four years in a commercial claims database was conducted. Patients with at least four years of claims experience between the years 2011 - 2017 were included in this study. Outcome measures were calculated for each year (Year 1 pre-index diagnosis, and Years 1, 2, and 3 post-index follow-up). Measures included healthcare costs (pharmacy and medical costs), medical costs, inpatient events, and emergency room visits. Unadjusted measures in the follow-up Year 1, Year 2, and Year 3 were compared to Year 1 pre-index. A separate multivariate analysis adjusting for age, sex, and comorbidities was conducted., Results: Among 1258 patients, mean adjusted healthcare costs were significantly higher in Year 1 post-index compared to Year 1 pre-index ($51,785 vs $41,441, p = < 0.05). In Year 2 ($36,937 vs $41,441, p = < 0.05) and 3 ($28,558 vs $41,441, p = < 0.05) post-index, mean adjusted healthcare costs decreased compared to Year 1 pre-index. Adjusted medical costs were similar in Year 1 ($25,034) post-index compared to Year 1 ($22,952) pre-index but were significantly lower in Year 2 ($15,242 vs $25,034, p = < 0.05) and Year 3 ($8,779 vs $25,034, p = < 0.05) post-index. The frequency of inpatient and emergency room events was significantly lower in all three observation periods following diagnosis in the unadjusted analysis. The adjusted analysis showed similar findings, except for emergency room visits, which were similar across all observation periods., Conclusion: Patients with AATD had substantial healthcare costs/utilization in the year before diagnosis. Costs were significantly higher in the first year following diagnosis. However, subsequent years showed cost reductions to levels below pre-diagnosis. These data support the need for strategies to reduce the time from symptom onset to diagnosis., Competing Interests: Declarations Ethics approval and consent to participate Higher healthcare cost and utilization before and after diagnosis of AATD in the United States, is a retrospective claims analysis.

Background: Vision screening as part of well-child visits is recommended annually for US children 3 to 6 years. However, 63% of children do not get a vision screening in well-child visits. The Patient-Centered Medical Home (PCMH) improves the receipt of preventive care visits in other medical specialties but it is unknown if it improves receipt of vision screening. The objective of this study is to determine whether caregiver-reported receipt of care in a PCMH is associated with receiving a vision screening test in a well-child visit for children 3 to 6 years in a pediatrician/general doctor's office ('primary care')., Method: Population-based data for US children aged 3 to 6 years was derived from the National Survey of Children's Health (2018-2019). Children were excluded if they did not have a well-child visit in the previous 12 months. The primary exposure was receipt of care in a PCMH ('PCMH care'), and the primary outcome was receipt of a vision screening in primary care. Adjusted odds ratios (aOR) and predicted probabilities were computed for children with and without PCMH care., Results: Among 9,587 children with well-child visits, 4,984 (50.9%) were males. There were 1,107 (23.3%) Hispanic, 6704 (52.8%) White/Non-Hispanic and 545 (11.8%) Black/Non-Hispanic children. There were 5,482 (51.8%) children who received PCMH care. Of those with PCMH care, 2,629 (52.2%) received a vision screening in primary care. Those with PCMH care (52.2%) had a higher odds of receiving a vision screening (aOR, 1.31; 95% CI 1.11, 1.55) in primary care compared to children without PCMH care (42.8%). The predicted probability of vision screening in primary care was 50.8% (95% CI 48.2, 53.5) for children that received PCMH care, and 44.3% (95% CI 41.3, 47.3) without PCMH care., Conclusions: Caregiver-reported receipt of PCMH care was associated with a greater likelihood of vision screening for children 3 to 6 years in a well-child visit. Further studies are needed to understand the mechanisms through which PCMH care contributes to the greater odds of vision screening in primary care to inform the creation of strategic interventions to prevent vision loss and its long-term implications., Competing Interests: Declarations Ethical approval and consent to participate This study was exempt from institutional review because it was a secondary analysis of a publicly available deidentified data set.

The long-term health impacts of niacin are still debated, and the association between dietary niacin and mortality risk in populations hasn't been extensively explored. This study included 26,746 US adults aged 20 years or older from the National Health and Nutrition Examination Survey 2003-2018, with a median follow-up of 9.17 years. During this period, there were 3,551 all-cause deaths, including 1,096 cardiovascular deaths. Cox models were used to compare hazard ratios (HRs) for mortality among participants grouped into different dietary niacin intake quartiles. Participants with the highest dietary niacin intake had a lower risk of all-cause mortality (HR 0.74, 95%CI 0.63-0.86) compared to those in the lowest intake quartile. For cardiovascular mortality, the HR was 0.73 (95%CI 0.57-0.95) in the highest niacin intake quartile. A dose-response relationship was revealed between dietary niacin intake and mortality by restricted cubic spline. Subgroup analysis showed a significant interaction between dietary niacin intake and diabetes concerning all-cause mortality (P = 0.046). In this population-based cohort study, higher dietary niacin intake correlates with lower risk of all-cause and cardiovascular mortality among US adults. The influence of niacin intake on all-cause mortality appears to be more significant in non-diabetic individuals compared to those with diabetes., Competing Interests: Declarations Ethics approval and consent to participate This study is an analysis derived from publicly available NHANES data.

Background: Cardiovascular disease (CVD) is a major global health concern with increasing incident cases and deaths. Homocysteine (Hcy) has been investigated for its potential association with CVD, researchers have debated the extent to which Hcy should be considered a risk factor for cardiovascular diseases, as only 50% of CVD can be explained by classical risk factors., Methods: We conducted a prospective cohort study using NHANES 1999-2006 data, analyzing 1,739 US patients aged at least 30 with CVD. Cox proportional hazards regression and restricted cubic splines were used to examine the relationship between Hcy levels and mortality, adjusting for covariates., Result: A total of 1,739 participants with cardiovascular disease (CVD) were enrolled, with a median follow-up period of 126 months. Among them, 1,194 participants died, including 501 deaths due to cardiovascular causes. After adjusting for covariates, the hazard ratios (HR) and 95% confidence intervals (CI) for CVD mortality at different levels of homocysteine (Hcy) (T1 (< 9.3), T2 (9.3-12.5), T3 (> 12.5)) were 1.26 (0.92, 1.73) (T2), and 1.69 (1.14, 2.51) (T3) (P for trend = 0.0086). The HR and 95% CI for all-cause mortality at different levels of Hcy were 1.22 (1.05, 1.42) (T2) and 1.64 (1.29, 2.09) (T3) (P for trend < 0.0001). Elevated Hcy levels were associated with increased risks of all-cause mortality and CVD deaths, even at levels below the conventional threshold. The nonlinear relationship was observed, with inflection points at 14.5 µmol/L for all-cause mortality and 14.6 µmol/L for CVD mortality. Subgroup analyses revealed interactions with age, serum vitamin B12, and smoking., Conclusion: Our study supports the notion that elevated Hcy levels are associated with higher all-cause and CVD mortality risks in CVD participants. The impact of Hcy on health outcomes can be observed at lower concentrations than previously thought., Competing Interests: Declarations Ethics approval and consent to participate The protocols of NHANES were approved by the institutional review board of the National Center for Health Statistics, CDC (https://www.cdc.gov/nchs/nhanes/).

Background: Inaccurate cancer news can have adverse effects on patients and families. One potential way to minimize this is through media literacy training-ideally, training tailored specifically to the evaluation of health-related media coverage., Purpose: We test whether an abbreviated health-focused media literacy intervention improves accuracy discernment or sharing discernment for cancer news headlines and also examine how these outcomes compare to the effects of a generic media literacy intervention., Methods: We employ a survey experiment conducted using a nationally representative sample of Americans (N = 1,200). Respondents were assigned to either a health-focused media literacy intervention, a previously tested generic media literacy intervention, or the control. They were also randomly assigned to rate either perceived accuracy of headlines or sharing intentions. Intervention effects on accurate and inaccurate headline ratings were tested using OLS regressions at the item-response level, with standard errors clustered on the respondent and with headline fixed effects., Results: We find that the health-focused media literacy intervention increased skepticism of both inaccurate (a 5.6% decrease in endorsement, 95% CI [0.1%, 10.7%]) and accurate (a 7.6% decrease, 95% CI [2.4%, 12.8%]) news headlines, and accordingly did not improve discernment between the two. The health-focused media literacy intervention also did not significantly improve sharing discernment. Meanwhile, the generic media literacy intervention had little effect on perceived accuracy outcomes, but did significantly improve sharing discernment., Conclusions: These results suggest further intervention development and refinement are needed before scaling up similarly targeted health information literacy tools, particularly focusing on building trust in legitimate sources and accurate content., (© The Author(s) 2024.

The Veterans Health Administration (VHA) provides maternity care by paying for Veterans to receive pregnancy-related care in community settings and by utilizing maternity care coordinators (MCCs) at each medical facility. The purpose of this qualitative descriptive study was to understand the MCC's experiences performing their role across VA facilities. Thirty MCCs were recruited and interviewed virtually using Microsoft Teams. Interviews were recorded and transcribed verbatim. Using thematic analysis, transcripts were coded, and themes were derived. MCC's roles include being a liaison, care coordinator, and supporter. MCCs improve Veterans' care during pregnancy and postpartum by education, monitoring health status, and connecting Veterans to providers within VA and the community. Across VA facilities, there was variation in how MCCs engaged with Veterans and in the services provided. A challenge shared was the lack of dedicated time to the role. In the VA, MCCs are valuable in ensuring high-quality care coordination of pregnant/postpartum Veterans despite the fragmentation of care between VA and community providers. To improve inconsistencies in how the MCC program is implemented, systematic strategies such as ensuring dedicated time are needed., (Published by Oxford University Press on behalf of the Society of Behavioral Medicine 2024.)
