Summary
Identifying smoking phenotypes is key for effective cessation. Tailoring treatments based on age, dependence, and therapy type improves quit rates in clinical practice.
Area of Science:
- Clinical Medicine
- Public Health
- Addiction Research
Background:
- Defining smoking phenotypes by variables like age, sex, and nicotine dependence is crucial for optimizing treatment efficacy.
- Current smoking cessation strategies may vary in effectiveness depending on individual patient characteristics.
Purpose of the Study:
- To define smoking phenotypes by analyzing combinations of patient variables.
- To guide the selection of the most effective smoking cessation treatments in routine clinical practice.
Main Methods:
- Retrospective review of clinical records from 3622 patients treated at a Smoking Cessation Service.
- Treatment programs included a combination of behavioral therapy and optional pharmacotherapy.
- Multivariate logistic regression analysis was used to identify factors influencing treatment outcomes.
Main Results:
- Continuous abstinence rates at 9-24 weeks were 57.7% for the overall sample.
- Nicotine Replacement Therapy showed reduced efficacy in highly dependent smokers.
- Younger smokers exhibited resistance to treatments, while low-dependence smokers responded well to various therapies, with bupropion and varenicline showing superior results.
Conclusions:
- Distinct smoking phenotypes exist, influencing the efficacy of different cessation treatments.
- Personalized treatment approaches based on identified phenotypes can enhance smoking cessation success.

01:23Drugs Acting on Autonomic Ganglia: Stimulants
2.2K
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...

1.9K
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...

1.6K
Ethanol, a clear colorless alcohol, has been consumed by humans for millennia, but its effects on the body are far from benign. At lower doses, it induces decreased inhibitions and loquaciousness, leading to its social appeal. However, it can cause severe consequences at higher doses, such as coma and respiratory depression, due to its zero-order elimination kinetics. Chronic ethanol abuse wreaks havoc on multiple organ systems, particularly the CNS and the liver. Abrupt cessation of ethanol...

1.6K
Drug dependence, abuse, and addiction are complex phenomena that can precipitate various abnormal states. Physical dependence refers to a state of pharmacological adaptation to a drug. This adaptation often results in tolerance—a reduced response to the drug after repeated administrations. When the drug use is abruptly stopped, withdrawal symptoms occur due to the body's need to readjust from the pharmacologically induced imbalance. However, tolerance and withdrawal symptoms do not...

Chronic bronchitis is a key phenotype of chronic obstructive pulmonary disease (COPD), characterized by airway-centered inflammation and mucus overproduction. It develops from long-term exposure to harmful particles or gases, most commonly cigarette smoke, which triggers a persistent inflammatory response.Cellular and Structural ChangesInflammation initially affects the large bronchi and later the smaller airways, with infiltration by immune cells, including neutrophils, macrophages, and...

Chronic obstructive pulmonary disease (COPD) is a group of lung conditions that progressively worsen over time, including chronic bronchitis and emphysema. This cluster of diseases collectively leads to a gradual and irreversible decline in lung function over time.
The primary cause for the onset of COPD is cigarette smoking and exposure to air pollution. These hazardous factors initiate a chain reaction within the lungs, resulting in chronic inflammation, damage to the airways, and a...
