Background: Health warnings may be less effective if they elicit reactance, a motivation to resist a threat to freedom, yet we lack a standard measure of reactance.
Purpose: We sought to validate a new health warning reactance scale in the context of pictorial cigarette pack warnings.
Methods: A national sample of adults (n = 1413) responded to reactance survey questions while viewing randomly assigned pictorial or text warnings on images of cigarette packs. A separate longitudinal sample of adult smokers received the warnings on their own cigarette packs (n = 46).
Results: Factor analyses identified a reliable and valid 27-item Reactance to Health Warnings Scale. In our experimental study, smokers rated pictorial warnings as being able to motivate quitting more than text warnings. However, five reactance scale factors weakened the warnings' impact (anger, exaggeration, government, manipulation, and personal attack; all p < .05).
Conclusions: The Reactance to Health Warnings Scale had good psychometric properties. Reactance weakened the impact of pictorial warnings on smokers' evaluation of the warning's ability to motivate quitting.

Ward-Based Staff Perspectives on Their Preparedness to Recognize Patient Deterioration: An Interpretive Description Study.
J Nurs Res
January 2025
College of Nursing & Health Science, Flinders University, Adelaide, Australia.
Background: Despite an overall decline in serious adverse events in hospitalized patients, approximately one third of inpatient mortality continues to relate to adverse events impacting patients on general wards. The preparedness of nurses, midwives, and nursing assistants (collectively referred to as ward-based staff) to recognize patient deterioration is therefore seen as critical.
Purpose: The aim of this study was to explore ward-based staff perspectives regarding their preparedness to recognize patient deterioration.
Romosozumab adverse event profile: a pharmacovigilance analysis based on the FDA Adverse Event Reporting System (FAERS) from 2019 to 2023.

Objective: This study aims to analyze adverse drug events (ADE) related to romosozumab from the second quarter of 2019 to the third quarter of 2023 from FAERS database.
Methods: The ADE data related to romosozumab from 2019 Q2 to 2023 Q3 were collected. After data normalization, four signal strength quantification algorithms were used: ROR (Reporting Odds Ratios), PRR (Proportional Reporting Ratios), BCPNN (Bayesian Confidence Propagation Neural Network), and EBGM (Empirical Bayesian Geometric Mean).
Small mammals and associated infections in China: a systematic review and spatial modelling analysis.

Background: As natural reservoirs of diverse pathogens, small mammals are considered a key interface for guarding public health due to their wide geographic distribution, high density and frequent interaction with humans.
Methods: All formally recorded natural occurrences of small mammals (Order: Rodentia, Eulipotyphla, Lagomorpha, and Scandentia) and their associated microbial infections in China were searched in the English and Chinese literature spanning from 1950 to 2021 and geolocated. Machine learning models were applied to determine ecological drivers for the distributions of 45 major small mammal species and two common rodent-borne diseases (RBDs), and model-predicted potential risk locations were mapped.
We present a 71-year-old man admitted to the intensive care unit with severe hypokalemia after ingesting licorice-containing confectionary over 6 weeks. Excess consumption of licorice with its active metabolite glycyrrhizic acid may precipitate pseudohyperaldosteronism with life-threatening hypokalemia. Public awareness and measures such as warning labels are needed to warn against excessive consumption.

Heatwaves are commonly simplified as binary variables in epidemiological studies, limiting the understanding of heatwave-mortality associations. Here we conduct a multi-country study across 28 East Asian cities that employed the Cumulative Excess Heatwave Index (CEHWI), which represents excess heat accumulation during heatwaves, to explore the potentially nonlinear associations of daytime-only, nighttime-only, and day-night compound heatwaves with mortality from 1981 to 2010. Populations exhibited high adaptability to daytime-only and nighttime-only heatwaves, with non-accidental mortality risks increasing only at higher CEHWI levels (75th-90th percentiles).
