Posttraumatic stress disorder (PTSD) is associated with increased rates of smoking although little is known regarding the mechanisms underlying this relationship. The current study examined expectations about smoking outcomes among smokers with and without PTSD. The sample included 96 veterans (mean age of 34 years) and included 17% women and 50% racial minorities. Smoking expectancies were measured with the Smoking Consequences Questionnaire-Adult (Copeland, Brandon, & Quinn, 1995). Consistent with previous work suggesting that smokers with PTSD smoke in an effort to reduce negative affect, unadjusted analyses indicated that smokers with PTSD (n = 38) had higher expectations that smoking reduces negative affect than smokers without PTSD (d = 0.61). Smokers with PTSD also had increased expectancies associated with boredom reduction (d = 0.48), stimulation (d = 0.61), taste/sensorimotor manipulation aspects of smoking (d = 0.73), and social facilitation (d = 0.61). Results of hierarchical linear regression analyses indicated that PTSD symptom severity was uniquely associated with these expectancies beyond the effects of gender and nicotine dependence. More positive beliefs about the consequences of smoking may increase risk of continued smoking among those with PTSD who smoke. Further understanding of smoking expectancies in this group may help in developing interventions tailored for this vulnerable population. 相似文献

Background:
Oral cancer remains the commonest form of cancer and cancer-related deaths among Indian males due to popularity of avoidable risk factors such as tobacco and alcohol use. A workplace oral cancer screening and tobacco cessation study was commenced on World No Tobacco Day 2007 at a chemical industry in rural Maharashtra.Aims:
The objectives were to screen the employees for oral neoplasia and to correlate it with their tobacco consumption pattern. In addition, the objective was to provide tobacco cessation services at the workplace.Materials and Methods:
This is an interventional cohort study among 104 employees of a chemical industrial unit in rural Maharashtra. Naked eye examination of the oral cavity was performed for all employees by a doctor irrespective of the tobacco habits at the beginning and at the end of 1 year. In between, the tobacco users were regularly examined during each follow-up.Statistical analysis used:
Through personal interviews of the participants, data were manually recorded and were transferred to electronic data base. Data analysis was conducted in STATA™ 8.2 on intention to treat basis.Results and Conclusions:
Among the 104 employees, 50 (48.08%) were current tobacco users at the beginning of the program. Oral precancers were seen exclusively among 20 (40%) tobacco users. After 1 year of workplace tobacco cessation intervention, 80% of oral precancers regressed. This shows that screening of the oral cavity at the workplace is effective when combined with tobacco cessation. 相似文献84.

Citrullus vulgaris (watermelon) is a fruit with prophylactic and therapeutic potentials. In an attempt to maximize these potentials, the seed and rind are now often consumed together with the pulp. This study aimed at evaluating the implications of such consumption. Study involved the use of 35 Wistar rats grouped into seven with a control group administered distilled water, and the other groups administered varying concentrations of the pulp and whole fruit for 28 days. Alanine and aspartate aminotransferase (ALT, AST) were assayed in the serum and liver. Total protein of the serum and selected tissues was determined and malondialdehyde (MDA) level measured. Phytochemical screening revealed the presence of steroids, saponin, alkaloids, flavonoids, and terpenoids in both whole fruit and pulp. Significant increases (p < 0.05) were seen in the liver ALT levels while there was a decreased (p < 0.05) intestinal total protein in the treatment groups. No significant (p ? 0.05) difference was seen in the serum and pancreas MDA levels while an increased (p < 0.05) intestinal MDA level was observed. Increased liver ALT levels in all the treatment groups might be due to high glutamate levels of C. vulgaris. Decreased (p ? 0.05) intestinal total protein might be indicative of protein loss, while elevated (p < 0.05) intestinal MDA levels in the groups administered whole fruit is suggestive of a defect in absorption at the intestinal epithelium. Hence, whole fruit consumption of C. vulgaris should be done with caution as it has potential to cause intestinal oxidative stress. 相似文献

Different kinds of anesthesia used in 2644 patients were analysed with special reference to the fact that patients with diseases of goiter had pronounced endocrine shifts. It was shown that there were no reasons to oppose different methods of anesthesia to one another. Each of them has its indications and contraindications corresponding to specific features of the disease. 相似文献
