Background: The health, social and economic consequences of the severe acute respiratory syndrome coronavirus (SARS-CoV-2, henceforth COVID-19) pandemic have loomed large as every national government made decisions about how to respond. The 40 Health Systems, COVID-19 (40HS, C-19) study aimed to investigate relationships between governments' capacity to respond (CTR), their response stringency, scope of COVID-19 testing and COVID-19 outcomes.
Methods: Data over March and April 2020 were extracted for 40 national health systems on prepandemic government CTR (Global Competitiveness Index), stringency measures (Oxford COVID-19 Government Response Tracker Stringency Index), approach to COVID-19 testing and COVID-19 cases and deaths (Our-World-in-Data). Multidimensional scaling (MDS) and cluster analysis were applied to examine latent dimensions and visualize country similarities and dissimilarities. Outcomes were tested using multivariate and one-way analyses of variances and Kruskal-Wallis H tests.
Results: The MDS model found three dimensions explaining 91% of the variance and cluster analysis identified five national groupings. There was no association between national governments' prepandemic CTR and the adoption of early stringent public health measures or approach to COVID-19 testing. Two national clusters applied early stringency measures and reported significantly lower cumulative deaths. The best performing national cluster (comprising Australia, South Korea, Iceland and Taiwan) adopted relatively early stringency measures but broader testing earlier than others, which was associated with a change in disease trajectory and the lowest COVID-19 death rates. Two clusters (one with high CTR and one low) both adopted late stringency measures and narrow testing and performed least well in COVID-19 outcomes.
Conclusion: Early stringency measures and intrinsic national capacities to deal with a pandemic are insufficient. Extended stringency measures, important in the short term, are not economically sustainable. Broad-based testing is key to managing COVID-19.

U.S. State-Level Containment Policies Not Associated with Food Insecurity Changes During the Early COVID-19 Pandemic: A Multi-level Analysis.

Johns Hopkins Center for a Livable Future, Johns Hopkins University, Baltimore, MD, 21205, USA.
Objective: To investigate the relationship between United States (US) containment measures during the COVID-19 pandemic and household food insecurity.
Design: To investigate these relationships, we developed a framework linking COVID-related containment policies with different domains of food security, then used multilevel random effects models to examine associations between state-level containment policies and household food security. Our framework depicts theorized linkages between stringency policies and five domains of food security (availability, physical access, economic access, acceptability in meeting preferences, and agency, which includes both self-efficacy and infrastructure).
Lack of correlation between school reopening and trends in adult COVID-19 hospitalisations and death rates during the Delta and early Omicron periods: An ecological analysis of five countries.

Objectives: In this ecological study, we describe SARS-CoV-2 case incidence and COVID-19 hospitalisation and death rates for school-aged and adult populations during the Delta and early Omicron periods, before and after schools reopened in five countries.
Methods: Data were extracted from government websites. Cases and COVID-19 hospitalisation and death incidence rates were calculated during the Delta and early Omicron periods in Australia, Canada, Denmark, Finland and the United Kingdom, for two weeks preceding and six weeks after schools reopened.
Beyond reliability: assessing rater competence when using a behavioural marker system.
Adv Simul (Lond)
December 2024
Medical Education Directorate, NHS Lothian, Edinburgh, UK.
Background: Behavioural marker systems are used across several healthcare disciplines to assess behavioural (non-technical) skills, but rater training is variable, and inter-rater reliability is generally poor. Inter-rater reliability provides data about the tool, but not the competence of individual raters. This study aimed to test the inter-rater reliability of a new behavioural marker system (PhaBS - pharmacists' behavioural skills) with clinically experienced faculty raters and near-peer raters.

Maintaining stringent conditions in SELEX (Systematic Evolution of Ligands by EXponential enrichment) is crucial for obtaining high-affinity aptamers. However, excessive stringency greatly increases the risk of SELEX failure. Controlling stringency has remained a technical challenge, largely dependent on intuition, due to the absence of a clear, quantitative measure of stringency.

Background: Rapid human movement plays a crucial role in the spatial dissemination of the dengue virus. Nevertheless, robust quantification of this relationship using both spatial and temporal models remains necessary. This study aims to explore the spatial and temporal patterns of dengue transmission under various human movement contexts.
