Summary
An interactive, tailored website significantly increased smokeless tobacco (ST) cessation rates compared to a basic website. This web-assisted program offers an effective method for adults seeking to quit ST.
Area of Science:
- Public Health
- Behavioral Science
- Digital Health Interventions
Background:
- Smokeless tobacco (ST) use is prevalent among adults, with many desiring to quit but lacking adequate resources.
- Developing accessible interventions is crucial for public health targets in tobacco cessation.
Purpose of the Study:
- To evaluate the efficacy of an interactive, tailored web-based intervention compared to a basic website for smokeless tobacco cessation.
- To assess the impact of tailored digital health tools on quitting behaviors.
Main Methods:
- A randomized trial involving 2523 adult ST users compared an Enhanced Condition (interactive, tailored website) with a Basic Condition (linear, text-based website).
- Follow-up rates at 3 and 6 months were recorded, with repeated point prevalence of tobacco use assessed.
- Complete Case and intent-to-treat analyses were employed to determine cessation rates.
Main Results:
- Participants in the Enhanced Condition demonstrated significantly higher quit rates for all tobacco use compared to the Basic Condition.
- Complete Case analysis showed 40.6% abstinence in the Enhanced Condition versus 21.2% in the Basic Condition (p < .001).
- Intent-to-treat analysis revealed quit rates of 12.6% (Enhanced) vs. 7.9% (Basic) (p < .001), with similar findings for ST-only use.
Conclusions:
- A tailored, interactive web-assisted cessation program is an efficacious method for assisting adult ST users to quit.
- Program exposure was significantly related to both cessation outcomes and attrition, highlighting the importance of engagement.

01:17Drug Dependence
Medications are typically administered to achieve therapeutic effects. Some drugs can modify an individual's mood and perception, frequently resulting in various enjoyable experiences. However, this can result in drug dependency, a condition marked by continuous drug use despite potential negative consequences. Drug dependency primarily falls into two categories: psychological and physical dependence. Psychological dependence occurs when the pleasurable feelings induced by the drug...
01:23Chronic Obstructive Pulmonary Disease II: Emphysema
Emphysema, a major phenotype of chronic obstructive pulmonary disease (COPD), is characterized by irreversible destruction of alveolar walls and permanent enlargement of distal airspaces. Unlike chronic bronchitis, which primarily affects the airways, emphysema predominantly involves the lung parenchyma, where structural damage leads to airflow limitation.PathophysiologyIt most commonly results from prolonged exposure to cigarette smoke and other toxic gases, particularly cigarette smoke.
01:26Assessment of the Mouth
A thorough mouth assessment, including inspection and palpation of the lips, gums, tongue, tonsils, uvula, and pharynx, is crucial in detecting potential health issues. Diseases ranging from oral cancer to systemic conditions like diabetes could be identified early through careful oral examination. This article provides a detailed guide on conducting a comprehensive mouth assessment.
Mouth Inspection
The inspection begins with visually examining the mouth for symmetry, color, and size.

01:29Chronic Obstructive Pulmonary Disease-V: Management
Managing Chronic Obstructive Pulmonary Disease (COPD) involves a multifaceted approach to reduce symptoms, prevent exacerbations, improve overall health status, and slow disease progression. Key strategies include lifestyle modifications, pharmacotherapy, supportive therapies, and, in some cases, surgery. Here is an overview of the primary COPD management strategies:

01:23Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
01:27Chronic Obstructive Pulmonary Disease-IV: Assessement and Diagnostic Studies
Assessing and diagnosing Chronic Obstructive Pulmonary Disease (COPD) involves a detailed approach that includes a comprehensive review of medical history, physical examination, and a variety of diagnostic tests. This thorough evaluation is essential to ensure an accurate diagnosis and guide effective management strategies.
