AI Article Synopsis
- Vaping, especially among adolescents, is a public health concern often likened to an epidemic, highlighting the need for a deeper understanding of its dynamics.
- A deterministic compartmental model was created to analyze adolescent e-cigarette use, considering social factors that affect starting, quitting, and relapsing behaviors.
- The study found that while social influences from temporary quitters were not impactful in the overall model, the influence from permanent quitters significantly affected smoking patterns, potentially leading to recurring outbreaks of vaping behavior.
Article Abstract
Vaping, or the use of electronic cigarettes (e-cigarettes), is an ongoing issue for public health. The rapid increase in e-cigarette usage, particularly among adolescents, has often been referred to as an epidemic. Drawing upon this epidemiological analogy between vaping and infectious diseases as a theoretical framework, we present a deterministic compartmental model of adolescent e-cigarette smoking which accounts for social influences on initiation, relapse, and cessation behaviours. We use results from a sensitivity analysis of the model's parameters on various response variables to identify key influences on system dynamics and simplify the model into one that can be analysed more thoroughly. We identify a single feasible endemic equilibrium for the proportion of smokers that decreases as social influence on cessation increases. Through steady state and stability analyses, as well as simulations of the model, we conclude that social influences from and on temporary quitters are not important in overall model dynamics, and that social influences from permanent quitters can have a significant impact on long-term system dynamics. In particular, we show that social influence on cessation can induce persistent recurrent smoking outbreaks.

Loneliness is an increasingly significant social and public health issue in contemporary societies. The available evidence suggests that social support is one of the key psychosocial processes for the reduction and prevention of loneliness. This study investigated the role played by sources of social support in the experience of social and emotional loneliness, identifying seven sources of support split between family (spouse/partner, children, grandchildren, siblings) and non-family (friends, neighbours).

Achieving greater diversity and inclusion in global dementia research requires the inclusion of underrepresented geographic, ethnic and regional populations such as indigenous Africans. The ADSP is a collaborative global initiative that includes sample collection across diverse populations, data generation including whole genome sequencing in over 120,000 individuals and multi-omics, the collating of rich phenotypic information, data harmonization, and unified data management and quality control. These datasets are being analyzed to accelerate our understanding of AD neurobiology with implications for better risk prediction and discovery of novel precision diagnostics and therapeutics.

Background: The salience network (SN) functions as a dynamic switch between the default mode network (DMN) and the frontoparietal network (FPN), aligning with salience and cognitive demand. Dysfunctions in SN activity within the cognitive and affective domains are linked to a wide range of deficits and maladaptive behavioral patterns in various clinical disorders. Emotion recognition is pivotal in social interactions and can be affected in neurodegenerative disorders.

Detection and attribution (DA) studies are cornerstones of climate science, providing crucial evidence for policy decisions. Their goal is to link observed climate change patterns to anthropogenic and natural drivers via the optimal fingerprinting method (OFM). We show that response theory for nonequilibrium systems offers the physical and dynamical basis for OFM, including the concept of causality used for attribution.

Despite welfare state expansion in liberal democracies during the 20th century, health inequalities between socio-economic groups persist. Understanding individuals' lived experiences can inform policy for reducing unequal health outcomes in these lives. We build on Fundamental Cause Theory (FCT), which posits that low socio-economic status is the fundamental cause of health problems in (later) life.
