While some and experiments have studied the toxic effects of e-cigarette (e-cig) components, the typical aerosol properties released from e-cigarettes have not been well characterized. In the present study, we characterized the variability in mass concentration and particle size distribution associated with the aerosol generation of different devices and e-liquid compositions in an experimental setup. The findings of this study indicate a large inter-day variability in the experiments, likely due to poor quality control in some e-cig devices, pointing to the need for a better understanding of all the factors affecting exposures in and experiments, and the development of standardized protocols for generation and measurement of e-cig aerosols.

Efficiency Analysis of Healthcare Systems in Latin American and Caribbean Countries: An Application Based on Data Envelopment Analysis.

Value Health Reg Issues

January 2025

Departamento de Ingeniería Informática, Facultad de Ingeniería, Universidad de Santiago de Chile, Santiago, Chile.

Objectives: Despite the increasing investments in Latin American healthcare, the corresponding improvement in population health is not proportional. This discrepancy may be attributed to the efficiency of resource utilization. This study used the data envelopment analysis (DEA) methodology to assess the efficiency of healthcare systems in 23 Latin American and Caribbean countries.

Background And Purpose: Even though Benign Paroxysmal Positioning Vertigo (BPPV) is one of the most reported vestibular disorders, its interaction with frailty and postural control in older adults is hardly or not investigated.

Methods: Thirty-seven older adults (≥65 years) with a diagnosis of BPPV (oaBPPV) (mean age 73.13 (4.

Work-related Fatigue: Relationship between Perceived and Performance Fatigability in Career Firefighters.

J Occup Environ Med

November 2024

Neuromuscular and Occupational Performance Laboratory, Department of Kinesiology and Sport Management, Texas Tech University, Lubbock, TX, United States.

Objective: The purpose of this study was to 1) examine the relationship between perceived work-related fatigue and performance fatigability, and 2) assess the impact of percent body fat (%BF) on perceived fatigue constructs in career firefighters.

Methods: Thirty-nine career firefighters completed body composition testing, the Occupational Fatigue Exhaustion Recovery (OFER15) scale assessing three subscales of work-related fatigue (acute fatigue, chronic fatigue, and inter-shift recovery), and maximal leg extensor isometric strength testing prior to and following an isotonic fatiguing protocol.

Results: Performance fatigability was not associated with any of the OFER15 perceived work-related fatigue variables (P ≥ 0.

Background: The idea of making science more accessible to nonscientists has prompted health researchers to involve patients and the public more actively in their research. This sometimes involves writing a plain language summary (PLS), a short summary intended to make research findings accessible to nonspecialists. However, whether PLSs satisfy the basic requirements of accessible language is unclear.

Eutrophication is one of the most relevant concerns due to the risk to water supply and food security. Nitrogen and phosphorus chemical species concentrations determined the risk and magnitude of eutrophication. These analyses are even more relevant in basins with intensive agriculture due to agrochemical discharges.
