Objective: Electronic nicotine delivery systems (ENDS; including e-cigarettes) are rapidly evolving in the US marketplace. This study reports cross-sectional prevalence and longitudinal pathways of ENDS use across 3 years, among US youth (12-17 years), young adults (18-24 years) and adults 25+ (25 years and older).
Design: Data were from the first three waves (2013-2016) of the Population Assessment of Tobacco and Health Study, a nationally representative, longitudinal cohort study of US youth and adults. Respondents with data at all three waves (youth, n=11 046; young adults, n=6478; adults 25+, n=17 188) were included in longitudinal analyses.
Results: Weighted cross-sectional ever use of ENDS increased at each wave. Across all three waves, young adults had the highest percentages of past 12-month, past 30-day (P30D) and daily P30D ENDS use compared with youth and adults 25+. Only about a quarter of users had persistent P30D ENDS use at each wave. Most ENDS users were polytobacco users. Exclusive Wave 1 ENDS users had a higher proportion of subsequent discontinued any tobacco use compared with polytobacco ENDS users who also used cigarettes.
Conclusions: ENDS use is most common among young adults compared with youth and adults 25+. However, continued use of ENDS over 2 years is not common for any age group. Health education efforts to reduce the appeal and availability of ENDS products might focus on reducing ENDS experimentation, and on reaching the smaller subgroups of daily ENDS users to better understand their reasons for use.

Theoretical approaches can help to plan, guide, and evaluate implementation projects that target real-world practice problems. This paper provides an overview of the integrated Promoting Action on Research Implementation in Health Services (i-PARIHS) framework and summarizes its use in nutrition and dietetics research and practice. A narrative summary of its use was compiled from the published literature based on citations from two key reference sources of the i-PARIHS framework.

This article presents a new set of semantic feature production norms, collected from 580 young adults, for 360 French concepts across various semantic categories. Although empirically derived feature norms have been developed for several languages and have been shown to be useful for investigating semantic memory and providing assessment tools, none are currently available for native French-speaking populations. In this study, the participants performed a property generation task in which they were asked to list features to describe the characteristics of each given concept (e.

Purpose: Given the increased likelihood for individuals with severe asthma to experience comorbidities, disease complications, emergency room visits, and hospitalizations, the ability to stratify asthma populations on severity is often important. Although pharmacoepidemiologic studies using administrative healthcare databases sometimes categorize asthma severity, there is no consensus on an approach.
Methods: Individuals with asthma (≥ 2 ICD-10-CM diagnosis codes J45) aged ≥ 6 years were identified in Optum's de-identified Clinformatics Data Mart Database between January 2017 and November 2023.

Objectives: To explore differences in beliefs towards running in adults with and without chronic low back pain.
Design: This convergent mixed methods cross-sectional study compared adults with chronic low back pain (n = 39) to pain-free adults with a history of chronic low back pain (n = 28) and a low back pain naive control group (n = 71).
Methods: Beliefs towards running (activity specific beliefs questionnaire; range: 1-4 points), pain intensity (101-point visual analogue scale), disability (Oswestry Disability Index), and habitual physical activity (International Physical Activity Questionnaire) were analysed.

The diagnosis of hemolysis is still based on straightforward biochemical parameters: haptoglobin (the most sensitive), lactate dehydrogenase (LDH), and unconjugated bilirubin. Anemia is not always present. Reticulocyte counts typically exceed 120×10/L, except in cases of associated vitamin deficiency or during the very early phase of acute hemolysis.
