Cooperation resonance based on link strategy reinforcement learning and conformity.

We propose a game model that integrates reinforcement learning (RL) with link strategies and conformity behavior to investigate the emergence and maintenance of cooperation. The model operates on a lattice network with periodic boundaries and includes two types of nodes: RL nodes with link strategies and conformist nodes. Simulation results reveal a range of critical mass.

Durable Immune Response and Long-term Efficacy of COVID-19 Vaccination in Children With Inflammatory Bowel Disease.

Background: Children with inflammatory bowel disease (IBD) may have diminished serologic response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccination and increased risk for subsequent severe coronavirus disease 2019 (COVID-19) infection. We sought to describe outcomes among those who developed SARS-CoV-2 infection following vaccination, characterize SARS-CoV-2 antibodies 1 year post-vaccination, and identify factors associated with durable serologic response.

Methods: We recruited children with IBD who received ≥2 doses of SARS-CoV-2 vaccine and prospectively collected data on (1) demographics, IBD characteristics, and therapy and (2) SARS-CoV-2 vaccination, testing, and infection symptoms.

Long-Term Effectiveness and Durability of COVID-19 Vaccination Among Patients With Inflammatory Bowel Disease.

Background And Aims: COVID-19 vaccination prevents severe disease in most patients with inflammatory bowel disease (IBD), but immunosuppressive medications can blunt serologic response. We followed adults with IBD for >1 year post-COVID-19 vaccination to describe factors associated with SARS-CoV-2 infection after vaccination, evaluate for a protective SARS-CoV-2 antibody level, characterize SARS-CoV-2 antibody persistence, and identify factors associated with humoral immune response durability.

Methods: Using a prospective cohort of COVID-19 immunized adults with IBD, we analyzed factors associated with SARS-CoV-2 infection after vaccination.

Early life exposures as risk factors for non-esophageal eosinophilic gastrointestinal diseases.

Objectives: Early life exposures increase risk of eosinophilic esophagitis (EoE), but it is unknown whether they contribute to increased risk for non-EoE eosinophilic gastrointestinal diseases (EGIDs). We aimed to assess the association between prenatal, antenatal, and early life factors and non-EoE EGIDs.

Methods: We conducted a case-control study based in EGID Partners, an online patient-centered research network.

Humoral Immune Response and Safety of SARS-CoV-2 Vaccination in Pediatric Inflammatory Bowel Disease.

Introduction: Children with inflammatory bowel disease (IBD) may respond differently to COVID-19 immunization as compared with healthy children or adults with IBD. Those younger than 12 years receive a lower vaccine dose than adults. We sought to describe the safety and humoral immune response to COVID-19 vaccine in children with IBD.

Epidemic Spreading in Metapopulation Networks Coupled With Awareness Propagation.

Understanding the feedback loop that links the spatiotemporal spread of infectious diseases and human behavior is an open problem. To study this problem, we develop a multiplex framework that couples epidemic spreading across subpopulations in a metapopulation network (i.e.

Factors Affecting Initial Humoral Immune Response to SARS-CoV-2 Vaccines Among Patients With Inflammatory Bowel Diseases.

Introduction: Although an additional coronavirus disease 2019 vaccine dose for immunocompromised persons has been recommended in some countries, further data to guide vaccination strategies for patients with inflammatory bowel disease (IBD) are urgently needed. We sought to identify factors affecting initial humoral immune response to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) vaccines among patients with IBD.

Methods: In this prospective cohort of SARS-CoV-2 immunized patients with IBD, we evaluated associations between participant age, sex, vaccine type, medication use, and the presence of a detectable antireceptor binding domain antibody and quantitative antibody level.

Impact of SARS-CoV-2 Vaccination on Inflammatory Bowel Disease Activity and Development of Vaccine-Related Adverse Events: Results From PREVENT-COVID.

Background: Severe acute respiratory syndrome coronavirus 2 vaccination is recommended for all individuals with inflammatory bowel disease (IBD), including those on immunosuppressive therapies; however, little is known about vaccine safety and efficacy in these patients or the impact of vaccination on IBD disease course.

Methods: We evaluated coronavirus disease 2019 (COVID-19) vaccine-related adverse events (AEs) and the effect of vaccination on IBD disease course among participants in the PREVENT-COVID (Partnership to Report Effectiveness of Vaccination in populations Excluded from iNitial Trials of COVID) study, a prospective, observational cohort study. Localized and systemic reactions were assessed via questionnaire.
