An accurate closed-form solution is obtained to the SIR Epidemic Model through the use of Asymptotic Approximants (Barlow et al., 2017). The solution is created by analytically continuing the divergent power series solution such that it matches the long-time asymptotic behavior of the epidemic model. The utility of the analytical form is demonstrated through its application to the COVID-19 pandemic.

Background And Objectives: Previous studies have shown inconsistent associations between red meat intake and cognitive health. Our objective was to examine the association between red meat intake and multiple cognitive outcomes.
Methods: In this prospective cohort study, we included participants free of dementia at baseline from 2 nationwide cohort studies in the United States: the Nurses' Health Study (NHS) and the Health Professionals Follow-Up Study (HPFS).
Sex Differences in Natural History and Health Outcomes Among Individuals With Tic Disorders.
Neurology
February 2025
Department of Neurology, Massachusetts General Hospital, Harvard Medical School, Boston, MA.
Objectives: To analyze sex differences in outcomes in Tourette syndrome (TS) and Persistent Motor or Vocal tic disorders (PMVT) in the Tourette Association of America International Consortium for Genetics (TAAICG) dataset.
Methods: The relationship between sex and clinical measures was explored in 2,403 participants (N = 2,109 with TS; N = 294 with PMVT) from the TAAICG dataset using generalized estimating equation regression models, and adjusted for age and family relationships.
Results: Female (vs male) participants with TS (25.

This study aimed to identify latent (unobservable) dimensions representing specific physical activity-related behaviors and explore their potential effects on obesity burden and spatial distribution in Colombia. A cross-sectional study (n = 9,658) was conducted based on the Colombian National Survey of Nutritional Status. A generalized structural equations model was proposed, combining exposure and measurement models to define a disease model.

This study aimed to evaluate the overall excess mortality and COVID-19 mortality in the regions of Brazil, in 2020, by sex and age group. An ecological study was carried out to calculate the overall excess mortality, by sex and age group, using the expected number of deaths in a non-pandemic context and the deaths observed in 2020. Data on deaths were extracted from the Brazilian Mortality Information System, in addition to population data from the Brazilian Institute of Geography and Statistics.
