Variability in constituents of e-cigarette products containing nicotine analogues

JAMA

2024-08-07

(Press-News.org) About The Study: Discrepancies were observed between labeled and measured concentrations of nicotine analogues in e-cigarettes and e-cigarette liquids marketed as nicotine replacements and exempt from FDA’s regulatory purview. Such discrepancies may lead to uncertainty about user exposure. When coupled with the largely unknown acute and chronic inhalation hazards and addictive potential of nicotine analogues, assessing product risk based on exposure becomes challenging from a clinical and regulatory standpoint. With e-cigarettes increasingly considered for smoking cessation, the advent of nicotine analogue–containing products with unknown health risks raises concern.

A vaping cessation text message program for adolescent e-cigarette users

2024-08-07

About The Study: A tailored, interactive text message intervention increased self-reported vaping cessation rates among adolescents recruited via social media channels. Quote from corresponding author Amanda L. Graham, PhD: “Health care providers, teachers, and parents have been asking how to help teens quit vaping. This study is a critical breakthrough that demonstrates the power of a behavioral intervention for vaping cessation. Text messages serve as powerful reminders of an initial commitment to quit and can deliver proven behavior change support right to a young person’s phone. “We also did not see evidence that teens who quit ...

Neighborhood socioeconomic disadvantage across the life course and premature mortality

2024-08-07

About The Study: Low neighborhood socioeconomic status was associated with premature mortality in this study. The risk of premature mortality was greatest among individuals experiencing persistently low neighborhood socioeconomic status from young to middle adulthood. Place-based interventions that target neighborhood social determinants of health should be designed from a life course perspective that accounts for early-life socioeconomic inequality.

Cocaine discovery could pave way for treatment for substance abuse

2024-08-07

You have probably heard of dopamine. The substance also known as the “feel-good hormone”. Drugs such as cocaine cause a surge of dopamine in the brain. Normally, a protein in the brain called the dopamine transporter (DAT) helps regulate dopamine levels and prevent the brain from thinking that every experience is pleasurable. However, when affected by cocaine, the brain is unable to regulate dopamine levels. Previously, researchers did not know how cocaine affects the different transporters in the brain, but a new study from the University of Copenhagen has changed that. “We have learned how cocaine binds to the dopamine transporter, which is ...

Link discovered between sensory neurons and breast cancer metastasis

2024-08-07

Cancer doesn’t grow in a vacuum—each tumor grows in a particular microenvironment within the body and spreads through a tangled web of vasculature and nerves. Scientists have come to understand that the most potent therapies address cancer in context—accounting for both the tumor and the support structure that forms around it. Now, a new paper in Nature reveals that the activation of sensory nerves within breast tumors is playing a critical role in promoting not only cancer growth but also its spread, known as metastasis. The findings—that sensory neurons ...

Plants show surprising diversity in arid landscape

2024-08-07

Understanding how plants cope with climatic extremes and grazing pressure is important for reliable prediction about future biodiversity and the functioning of dryland ecosystems[1]. An international team, coordinated by KAUST’s Fernando Maestre, has assessed how 20 chemical and morphological plant functional traits jointly respond to changes in aridity and grazing pressure across global drylands. Increasing aridity and grazing pressure could be expected to reduce the level of plant diversity. However, the diversity of plant traits — including key traits linked to nutrient cycling such as specific leaf area and foliar ...

Plasma bubbles and the “engine” of fast radio bursts

2024-08-07

Rome, 7 August 2024 -- Fast Radio Bursts (FRBs) are one of the most recent open mysteries of modern astrophysics. Within a few milliseconds, these powerful events release an immense amount of energy, among the highest observable in cosmic phenomena. FRBs were discovered just over ten years ago and mostly arise from extragalactic sources. Their origin, however, is still uncertain and there are huge ongoing efforts by the astrophysics community around the world to understand the physical processes behind them. In very few cases, the rapid flash that characterises FRBs coincides with a persistent ...
