Article Abstract
During an infectious disease outbreak, mathematical models and computational simulations are essential tools to characterize the epidemic dynamics and aid in design public health policies. Using these tools, we provide an overview of the possible scenarios for the COVID-19 pandemic in the phase of easing restrictions used to reopen the economy and society. To investigate the dynamics of this outbreak, we consider a deterministic compartmental model (SEIR model) with an additional parameter to simulate the restrictions. In general, as a consequence of easing restrictions, we obtain scenarios characterized by high spikes of infections indicating significant acceleration of the spreading disease. Finally, we show how such undesirable scenarios could be avoided by a control strategy of successive partial easing restrictions, namely, we tailor a successive sequence of the additional parameter to prevent spikes in phases of low rate of transmissibility.

Restrictive State Opioid Treatment Program Regulations Constrain Local Access To Methadone Maintenance Treatment.
Health Aff (Millwood)

State regulations governing opioid treatment programs (OTPs) vary widely in their restrictiveness, but how they affect geographic access to methadone maintenance treatment for opioid use disorder remains poorly understood. In this study of comprehensive data on methadone shipments to OTPs in 2019, we found that ZIP codes just across the border in states with low restrictiveness in OTP regulations had more than twice the OTP density and methadone shipments compared with nearby and otherwise similar ZIP codes in states with high restrictiveness. These findings suggest that restrictive state OTP regulations constrain geographic access to methadone maintenance treatment and that easing such restrictions is a viable strategy to expand access.

Increases in adolescent loneliness were a significant concern during the lockdowns of the COVID-19 pandemic. We use longitudinal survey data from the Cannabis Use, Obesity, Mental Health, Physical Activity, Alcohol Use, Smoking, and Sedentary Behavior study from 2017 to 2023 to assess whether increases in loneliness correspond to lockdowns, whether different cohorts differ in the trajectories of loneliness ratings and whether social support and relationships impact the course of loneliness throughout secondary school. We compared linear latent growth models and latent basis growth models of annual repeated measures of loneliness from three 4-year cohorts of Canadian high school students ( = 5,237, female = 3,166, 80.

This study examines the impact of easing COVID-19 restrictions on heavy metal concentrations in paddy soil and rice in Mizoram, India (2021-2023). Concentrations of copper, manganese, zinc, iron, nickel, lead, arsenic, and cadmium were measured using ICP-MS. The Bioaccumulation Factor, Pollution Index, and Health Risk Index were calculated, which assessed metal uptake, pollution level, and health hazards, respectively.

PurposeVirtual General Surgery residency interviews remain common despite the easing of travel restrictions and health risks associated with the spread of COVID-19. The primary benefits of virtual interviews include time and cost savings for applicants and programs alike. Despite these benefits, many have advocated for a return to the in-person setting, citing improved ability for applicants to assess the intangibles of a program.
