The contemporary scientific community places a growing emphasis on the reproducibility of research. The projects R package is a free, open-source package created in the interest of facilitating reproducible research workflows. It adds to existing software tools for reproducible research and introduces several practical features that are helpful for scientists and their collaborative research teams. For each individual project, it supplies a framework for storing raw and cleaned study data sets, and it provides script templates for protocol creation, data cleaning, data analysis and manuscript development. Internal databases of project and author information are generated and displayed, and manuscript title pages containing author lists and their affiliations are automatically generated from the internal database. File management tools allow teams to organize multiple projects. When used on a shared file system, multiple researchers can harmoniously contribute to the same project in a less punctuated manner, reducing the frequency of misunderstandings and the need for status updates.

In epidemiology, gerontology, human development and the social sciences, age-period-cohort (APC) models are used to study the variability in trajectories of change over time. A well-known issue exists in simultaneously identifying age, period and birth cohort effects, namely that the three characteristics comprise a perfectly collinear system. That is, since age = period−cohort, only two of these effects are estimable at a time. In this paper, we introduce an alternative framework for considering effects relating to age, period and birth cohort. In particular, instead of directly modeling age in the presence of period and cohort effects, we propose a risk modeling approach to characterize age-related risk (i.e., a hybrid of multiple biological and sociological influences to evaluate phenomena associated with growing older). The properties of this approach, termed risk-period-cohort (RPC), are described in this paper and studied by simulations. We show that, except for pathological circumstances where risk is uniquely determined by age, using such risk indices obviates the problem of collinearity. We also show that the size of the chronological age effect in the risk prediction model associates with the correlation between a risk index and chronological age and that the RPC approach can satisfactorily recover cohort and period effects in most cases. We illustrate the advantages of RPC compared to traditional APC analysis on 27496 individuals from NHANES survey data (2005–2016) to study the longitudinal variability in depression screening over time. Our RPC method has broad implications for examining processes of change over time in longitudinal studies. [ABSTRACT FROM AUTHOR]

Background: Community members may provide useful perspectives on manuscripts submitted to medical journals. Objective: To determine the impact of community members reviewing medical journal manuscripts. Design: Randomized controlled trial involving 578 original research manuscripts submitted to two medical journals from June 2018 to November 2021. Participants: Twenty-eight community members who were trained, supervised, and compensated. Interventions: A total of 289 randomly selected control manuscripts were reviewed by scientific reviewers only. And 289 randomly selected intervention manuscripts were reviewed by scientific reviewers and one community member. Journal editorial teams used all reviews to make decisions about acceptance, revision, or rejection of manuscripts. Main Measures: Usefulness of reviews to editors, content of community reviews, and changes made to published articles in response to community reviewer comments. Key Results: Editor ratings of community and scientific reviews averaged 3.1 and 3.3, respectively (difference 0.2, 95% confidence interval [CI] 0.1 to 0.3), on a 5-point scale where a higher score indicates a more useful review. Qualitative analysis of the content of community reviews identified two taxonomies of themes: study attributes and viewpoints. Study attributes are the sections, topics, and components of manuscripts commented on by reviewers. Viewpoints are reviewer perceptions and perspectives on the research described in manuscripts and consisted of four major themes: (1) diversity of study participants, (2) relevance to patients and communities, (3) cultural considerations and social context, and (4) implementation of research by patients and communities. A total of 186 community reviewer comments were integrated into 64 published intervention group articles. Viewpoint themes were present more often in 66 published intervention articles compared to 54 published control articles (2.8 vs. 1.7 themes/article, difference 1.1, 95% CI 0.4 to 1.8). Conclusions: With training, supervision, and compensation, community members are able to review manuscripts submitted to medical journals. Their comments are useful to editors, address topics relevant to patients and communities, and are reflected in published articles.

Background: Social and ecological differences in early SARS-CoV-2 pandemic screening and outcomes have been documented, but the means by which these differences have arisen are not well understood. Objective: To characterize socioeconomic and chronic disease-related mechanisms underlying these differences. Design: Observational cohort study. Setting: Outpatient and emergency care. Patients: 12900 Cleveland Clinic Health System patients referred for SARS-CoV-2 testing between March 17 and April 15, 2020. Interventions: Nasopharyngeal PCR test for SARS-CoV-2 infection. Measurements: Test location (emergency department, ED, vs. outpatient care), COVID-19 symptoms, test positivity and hospitalization among positive cases. Results: We identified six classes of symptoms, ranging in test positivity from 3.4% to 23%. Non-Hispanic Black race/ethnicity was disproportionately represented in the group with highest positivity rates. Non-Hispanic Black patients ranged from 1.81 [95% confidence interval: 0.91–3.59] times (at age 20) to 2.37 [1.54–3.65] times (at age 80) more likely to test positive for the SARS-CoV-2 virus than non-Hispanic White patients, while test positivity was not significantly different across the neighborhood income spectrum. Testing in the emergency department (OR: 5.4 [3.9, 7.5]) and cardiovascular disease (OR: 2.5 [1.7, 3.8]) were related to increased risk of hospitalization among the 1247 patients who tested positive. Limitations: Constraints on availability of test kits forced providers to selectively test for SARS-Cov-2. Conclusion: Non-Hispanic Black patients and patients from low-income neighborhoods tended toward more severe and prolonged symptom profiles and increased comorbidity burden. These factors were associated with higher rates of testing in the ED. Non-Hispanic Black patients also had higher test positivity rates. [ABSTRACT FROM AUTHOR]

Objective Epilepsy is a common neurological condition that is often associated with stigmatizing attitudes and negative stereotypes among the general public. This randomized controlled trial ( RCT) tested two new communication approaches targeting epilepsy stigma versus an education-alone approach. Methods Two brief stigma-reduction videos were developed, informed by community stakeholder input; one highlighted role competency in people with epilepsy; the other highlighted social inclusion of people with epilepsy. A control video was also developed. A Web-based survey using a prospective RCT design compared effects of experimental videos and control on acceptability, perceived impact, epilepsy knowledge, and epilepsy stigma. Epilepsy knowledge and stigma were measured with the Epilepsy Knowledge Questionnaire ( EKQ) and Attitudes and Beliefs about Living with Epilepsy ( ABLE), respectively. Results A total of 295 participants completed the study. Mean age was 23.1 ( standard deviation = 3.27) years; 59.0% were male, and 71.4% were white. Overall, respondents felt videos impacted their epilepsy attitudes. EKQ scores were similar across videos, with a trend for higher knowledge in experimental videos versus control (p = 0.06). The role competency and control videos were associated with slightly better perceived impact on attitudes. There were no differences between videos on ABLE scores (p = 0.568). There were subgroup differences suggesting that men, younger individuals, whites, and those with personal epilepsy experience had more stigmatizing attitudes. Significance This RCT tested communication strategies to improve knowledge and attitudes about epilepsy. Although this initial effort will require follow-up, we have demonstrated the acceptability, feasibility, and potential of novel communication strategies to target epilepsy stigma, and a Web-based approach for assessing them.

ALCOHOL drinking , *HEPATITIS , *HEPATITIS C , *MEDICAL care , *PEOPLE with alcoholism , *PATIENTS - Abstract
Background: Abstaining from alcohol consumption is generally recommended for patients with Hepatitis C(HCV). However, mixed research findings coupled with a lack of consistent guidelines on alcohol consumption and HCV may influence what healthcare providers tell their HCV patients about drinking. This may be more problematic when advising nonharmful drinkers with HCV, a population for whom consumption would not bea problem in the absence of their HCV diagnosis.Objective: This study explores what healthcare providers advise their HCV patients who are drinking alcohol at nonharmful levels about alcohol use and what these patients actually hear.Design: We conducted separate focus groups and interviews about alcohol use and HCV with nonharmful drinkers with HCV (N=50) and healthcare providers (N=14) at a metropolitan teaching hospital. All focus groups and interviews were audio-taped, transcribed, and analyzed using NVivo, a qualitative data management and analysis program.Results: We found similar themes about HCV and alcohol consumption (stop completely, occasional drink is ok, cut down, and provision of mixed/ambiguous messages), reported by both providers and patients.Patient respondents who reported hearing “stop completely”were more likely to have had their last medical visit at the gastroenterology (GI) clinic as opposed to the internal medicine (IM) clinic. Furthermore, IM providers were more likely to give their recommendations in“medical language” than were GI providers.Conclusions: To make the best health-related decisions about their disease, HCV patients need consistent information about alcohol consumption. Departments of Internal Medicine can increase provider knowledge about HCV and alcohol use by providing more education and training on HCV. [ABSTRACT FROM AUTHOR]- Published
