Environmental sampling surveillance (ESS) technologies, such as wastewater genomic surveillance and air sensors, have been increasingly adopted during the COVID-19 pandemic to provide valuable information for public health response. However, ESS coverage is not universal, and public health decision-makers need support to choose whether and how to expand and sustain ESS efforts. This paper introduces a model and approach to quantify the value of ESS systems that provide leading epidemiological indicators for pandemic response.

Article Synopsis
  • Policymakers employed non-pharmaceutical interventions (NPIs) to curb COVID-19 transmission before vaccines were available, but research on their effectiveness remains limited and inconsistent across various studies.
  • This study analyzed 61 articles from China, Italy, the UK, and the US to evaluate the impact of NPIs on reducing disease transmission, finding substantial variation in their effectiveness estimates.
  • NPIs can reduce transmission by 40 to 90%, with stricter interventions like lockdowns showing greater effectiveness, but a lack of standard definitions and categories hinders comparability among studies.

Purpose: To determine the prevalence of sleep disturbances in patients before and after arthroscopic surgery of the shoulder and to evaluate the association between patient-reported outcomes and standardized sleep disturbance tools after shoulder arthroscopy.

Methods: A systematic review, following PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-analyses) guidelines, was conducted by searching the PubMed, Embase, and Scopus databases using the terms "arthroscopic surgery" and "sleep." Two independent reviewers evaluated the studies based on the inclusion criteria focused on the effects of shoulder arthroscopy on sleep disturbance and the use of outcome measures related to sleep.

Background: "Clean" dietary labels are often viewed by consumers as referencing products that are minimally processed, without additives, preservatives, artificial colors, or ingredients, but may also be interpreted as vegan, gluten-free, dairy-free, "real," or "natural." Although the "clean" diet trend continues to grow in popularity, there is a lack of consensus regarding the definition and use of this terminology with a corresponding lack of regulation for such labels in the United States.

Method: This multidisciplinary scoping review examines the public health implications of the "clean" label trend and the legal and policy landscape for regulation.
