Effectiveness of Nicotine Withdrawal Symptoms Management Program Using LINE Application to Increase Self-Efficacy for Industrial Workers

Background: Smoking is a risk factor for chronic diseases. A combination of tobacco use with occupational hazards among industrial workers could increase the risk of occupational disease and injury. Nicotine is known to be highly addictive. It is difficult not only to maintain the decrease in smoking but also to continue quitting tobacco use. Moreover, nicotine withdrawal can be challenging and lead to failure in the smoking cessation process. Self-efficacy theory has been used recently for the development of effective smoking cessation programs. Objective: To develop an online nicotine withdrawal symptoms management program based on self-efficacy theory and examine its effectiveness. Materials and Methods: A quasi-experimental design with a control group pretest-posttest design was used. The sample consisted of male employees working in a consumer product manufacturing industry in Bangkok. An intervention group (n=28) received an online nicotine withdrawal symptoms management program via LINE application based on self-efficacy theory for one month. In comparison, participants in the control group (n=29) received a conventional smoking cessation program. The effectiveness of the intervention on nicotine withdrawal symptoms, cigarette craving, self-efficacy perception of nicotine withdrawal management, cigarette rolls per day, nicotine dependence level, exhaled carbon monoxide level, and smoking cessation behavior the first and fourth week were examined using a repeated-measures analysis of variance. Results: At one-month follow-up, there were significant differences between the two groups on nicotine withdrawal symptoms score, cigarette craving level, self-efficacy perception of nicotine withdrawal management, cigarette rolls per day, nicotine addiction level, exhaled carbon monoxide level, and smoking cessation behaviors (p<0.001). In addition, there was a significant difference in the self-reported nicotine withdrawal symptoms score in terms of irritability, anger, anxiety, concentration deficit, depression, and insomnia (p<0.001) between groups, between times, and between times and groups (p<0.001). Conclusion: Nicotine withdrawal symptoms management program using LINE application is effective in encouraging smoking cessation.

Effect 1 of NMDA Receptor Agonist and Antagonist on Nicotine withdrawal induced Hyperexcitability in Mice

Kynurenic acid is a recognized broad-spectrum antagonist of excitatory amino acid receptors with a particularly high affinity for the glycine co-agonist site of the N-methyl-D-aspartate (NMDA) receptor complex. D- Cycloserine is a NMDA receptor partial agonist which facilitate in an initiation of nicotine withdrawal symptoms and dependence. Thus, the influence of kynurenic acid treatment on the development and expression of nicotine dependence was tested by using the nicotine withdrawal-induced hyperexcitability paradigm. Mice were provided with a nutritionally balanced control liquid diet as the sole nutrient source on day 0; from day 1–4 (nicotine 25µg), from day 5–7 (nicotine, 50ug) and from day 8–10 (nicotine, 100ug) was incorporated into the liquid diet. On day 11, the nicotine liquid diet was replaced with nutritionally balanced control liquid diet, and nicotine withdrawal-induced hyperexcitability signs were recorded. The results revealed that acute administration of kunurenic acid (50 and 100mg/kg, i.p.) dose-dependently attenuated nicotine withdrawal-induced hyperexcitability signs, and these results were comparable to D- Cycloserine (50 and 100mg/kg, i.p.) Further, chronic administration of kunurenic acid (50 and 100mg/kg, i.p.) to the nicotine diet fed mice markedly attenuated the nicotine withdrawal-induced hyperexcitability signs. In conclusion, the results and evidence suggest that kinurenic acid exhibited an inhibitory influence against nicotine withdrawal-induced hyperexcitability signs, which could be mediated through its neuromodulatory action.
