RESUMEN

Importance: Persistent smoking may cause adverse outcomes among patients with cancer. Many cancer centers have not fully implemented evidence-based tobacco treatment into routine care. Objective: To determine the effectiveness of sustained telephone counseling and medication (intensive treatment) compared with shorter-term telephone counseling and medication advice (standard treatment) to assist patients recently diagnosed with cancer to quit smoking. Design, Setting, and Participants: This unblinded randomized clinical trial was conducted at Massachusetts General Hospital/Dana-Farber/Harvard Cancer Center and Memorial Sloan Kettering Cancer Center. Adults who had smoked 1 cigarette or more within 30 days, spoke English or Spanish, and had recently diagnosed breast, gastrointestinal, genitourinary, gynecological, head and neck, lung, lymphoma, or melanoma cancers were eligible. Enrollment occurred between November 2013 and July 2017; assessments were completed by the end of February 2018. Interventions: Participants randomized to the intensive treatment (n = 153) and the standard treatment (n = 150) received 4 weekly telephone counseling sessions and medication advice. The intensive treatment group also received 4 biweekly and 3 monthly telephone counseling sessions and choice of Food and Drug Administration-approved cessation medication (nicotine replacement therapy, bupropion, or varenicline). Main Outcome and Measures: The primary outcome was biochemically confirmed 7-day point prevalence tobacco abstinence at 6-month follow-up. Secondary outcomes were treatment utilization rates. Results: Among 303 patients who were randomized (mean age, 58.3 years; 170 women [56.1%]), 221 (78.1%) completed the trial. Six-month biochemically confirmed quit rates were 34.5% (n = 51 in the intensive treatment group) vs 21.5% (n = 29 in the standard treatment group) (difference, 13.0% [95% CI, 3.0%-23.3%]; odds ratio, 1.92 [95% CI, 1.13-3.27]; P < .02). The median number of counseling sessions completed was 8 (interquartile range, 4-11) in the intensive treatment group. A total of 97 intensive treatment participants (77.0%) vs 68 standard treatment participants (59.1%) reported cessation medication use (difference, 17.9% [95% CI, 6.3%-29.5%]; odds ratio, 2.31 [95% CI, 1.32-4.04]; P = .003). The most common adverse events in the intensive treatment and standard treatment groups, respectively, were nausea (n = 13 and n = 6), rash (n = 4 and n = 1), hiccups (n = 4 and n = 1), mouth irritation (n = 4 and n = 0), difficulty sleeping (n = 3 and n = 2), and vivid dreams (n = 3 and n = 2). Conclusions and Relevance: Among smokers recently diagnosed with cancer in 2 National Cancer Institute-designated Comprehensive Cancer Centers, sustained counseling and provision of free cessation medication compared with 4-week counseling and medication advice resulted in higher 6-month biochemically confirmed quit rates. However, the generalizability of the study findings is uncertain and requires further research. Trial Registration: ClinicalTrials.gov Identifier: NCT01871506.

RESUMEN

The aim of this study was to investigate the effects of positive group psychotherapy with auricular acupressure on tobacco withdrawal symptoms and smoking cessation. This study used a randomized controlled trial design. Participants were randomly assigned to 1 of 3 groups: group 1 (counseling and auricular acupressure), group 2 (counseling and placebo acupressure), and the control group (self-help for smoking cessation). Positive group psychotherapy and auricular acupressure were performed once a week for 6 weeks. The smoking cessation rates for 1 year in groups 1 and 2 were higher than that in the control group (9.5%, 15.6%, and 0%, respectively; odd ratio: 7.98, P = .019, n = 109). There was a significant difference of tobacco withdrawal symptoms among the 3 groups over 4 weeks (F = 2.9, P = .04). The mean differences between week 1 and week 4 among the 3 groups were statistically significant (4.7 ± 6.96, 5.18 ± 7.9, and 0.14 ± 7.15, F = 4.25, P = .018).

RESUMEN

Wastewater analysis is a powerful method that can provide useful information about the abuse of legal and illicit drugs. The aim of our study was to determine nicotine consumption during four different music festivals and to find a connection between smoking and preferences for specific music styles using wastewater analysis. The amount of the nicotine metabolite cotinine was monitored in wastewater at the influent of three waste water treatment plants WWTPs in the Czech Republic and Slovakia, where the festivals took place. Urinary bio-markers of nicotine utilization were analyzed by LC-HRMS. More than 80,000 festival participants were monitored during our study from June to September 2014. A significant increase of nicotine consumption was observed in wastewaters during music festivals. The nicotine ingestion level was back-calculated and expressed as mass of pure drug consumed per day and per 1000 inhabitants for selected cities of both countries. The highest differences between typical levels of cotinine in wastewaters and the levels during music festivals were detected in Piestany: 4 g/L/1000 inhabitants during non-festival days compared to 8 g/L/1000 inhabitants during the Topfest pop-rock festival and 6g/L/1000 inhabitants during the Grape dance festival. No significant increase of the amounts of cotinine in wastewater was recorded for the Country and Folk festivals.

RESUMEN

BACKGROUND AND OBJECTIVES: We assessed the feasibility of a new cognitive behavioral therapy (CBT) manual, plus transdermal patch nicotine replacement therapy (NRT), to treat co-occurring nicotine and cannabis dependence. METHOD: Seven of 12 (58.3%) adults with DSM-IV diagnoses of both nicotine and cannabis dependence completed 10 weeks of individual CBT and NRT. RESULTS: Participants smoked 12.6 ± 4.9 tobacco cigarettes per day at baseline, which was reduced to 2.1 ± 4.2 at the end of treatment (F[5] = 23.5, p < .0001). The reduction in cannabis use from 10.0 ± 5.3 inhalations per day at baseline to 8.0 ± 5.3 inhalations per day at 10 weeks was not significant (F[5] = 1.12, p = .37). There was a significant decrease from the mean baseline Fagerstrom Test for Nicotine Dependence scores at weeks 4, 6, 8, and 10 of treatment (F[4] = 19.8, p < .001) and mean Client Satisfaction Questionnaire scores were uniformly high (30.6 ± 1.9). CONCLUSIONS AND SCIENTIFIC SIGNIFICANCE: A CBT plus NRT treatment program significantly reduced tobacco smoking but did not significantly reduce cannabis use in individuals with co-occurring nicotine and cannabis dependence. There was no compensatory increase in cannabis use following the reduction in tobacco smoking, suggesting that clinicians can safely pursue simultaneous treatment of co-occurring nicotine and cannabis dependence. The intervention was well-liked by the 7 of the 12 enrollees who completed the study.

RESUMEN

BACKGROUND: Tobacco smoking remains the leading preventable cause of death among American women. Aerobic exercise has shown promise as an aid to smoking cessation because it improves affect and reduces nicotine withdrawal symptoms. Studies outside the realm of smoking cessation have shown that yoga practice also reduces perceived stress and negative affect. METHODS: This pilot study examines the feasibility and initial efficacy of yoga as a complementary therapy for smoking cessation. Fifty-five women were given 8-week group-based cognitive behavioral therapy for smoking cessation and were randomized to a twice-weekly program of Vinyasa yoga or a general health and wellness program (contact control). The primary outcome measure was 7-day point prevalence abstinence at the end of treatment validated by saliva cotinine testing. Longitudinal analyses were also conducted to examine the effect of intervention on smoking cessation at 3- and 6-month follow-up. We examined the effects of the intervention on potential mediating variables (e.g., confidence in quitting smoking, self-efficacy), as well as measures of depressive symptoms, anxiety, and perceived health (SF-36). RESULTS: At end of treatment, women in the yoga group had a greater 7-day point-prevalence abstinence rate than controls (odds ratio [OR], 4.56; 95% CI, 1.1-18.6). Abstinence remained higher among yoga participants through the six month assessment (OR, 1.54; 95% CI, 0.34-6.92), although differences were no longer statistically significant. Women participating in the yoga program also showed reduced anxiety and improvements in perceived health and well-being when compared with controls. CONCLUSIONS: Yoga may be an efficacious complementary therapy for smoking cessation among women.

RESUMEN

OBJECTIVE: To evaluate the influence of maternal smoking on antioxidative capacity and intensity of oxidative damage in breast milk. STUDY DESIGN: The study group (n=30) was comprised of postpartum women who declared smoking more than five cigarettes per day during pregnancy and lactation (confirmed by the urinalysis of cotinine concentration), and their newborns. Control group included 29 non-smoking postpartum women and their newborns. Colostrum samples were collected on the 3rd day after delivery and breast milk samples between the 30th and the 32nd day after delivery. Morning maternal and neonatal urine samples were obtained on the day of the mature milk sampling. Isoprostane concentrations in colostrum/mature milk and urine were determined immunoenzymatically. Total Antioxidant Status (TAS) of colostrum/breast milk was determined by Rice-Evans and Miller method. RESULT: Colostrum TAS in smokers was significantly lower than in non-smokers (P=0.006). In both groups, the TAS of mature milk was higher compared with colostrum, but significant differences were observed amongst smokers only (P=0.001). In smokers the isoprostane concentration of mature milk was significantly higher than the colostrum concentration (P=0.001). Significant inverse correlation between maternal urinary isoprostane concentration and the TAS of mature breast milk was observed in smokers (R=-0.525, P=0.023), but not in non-smokers (R=0.161, P=0.422). CONCLUSION: This study revealed that maternal smoking triggers harmful effects on an infant by impairing pro-oxidant-antioxidant balance of breast milk.

RESUMEN

Maternal nicotine (NIC) exposure during lactation leads to overweight, hyperleptinemia, and hypothyroidism in adult rat offspring. In this model, we analyzed adipocyte morphology, glucose homeostasis (serum insulin and adiponectin; liver and muscle glycogen), serum lipid, and the leptin signaling pathway. After birth, osmotic minipumps were implanted in lactating rats, which were divided into the groups NIC (6 mg/kg per day s.c. for 14 days) and control (C, saline). NIC and C offspring were killed at the age of 180 days. Adult NIC rats showed higher total body fat (+10%, P<0.05), visceral fat mass (+12%, P<0.05), and cross-sectional area of adipocytes (epididymal: +12% and inguinal: +43%, P<0.05). Serum lipid profile showed no alteration except for apolipoprotein AI, which was lower. We detected a lower adiponectin:fat mass ratio (-24%, P<0.05) and higher insulinemia (+56%, P<0.05), insulin resistance index (+43%, P<0.05), leptinemia (+113%, P<0.05), and leptin:adiponectin ratio (+98%, P<0.05) in the adult NIC group. These rats presented lower hypothalamic contents of the proteins of the leptin signaling pathway (leptin receptor (OB-R): -61%, janus tyrosine kinase 2: -41%, and p-signal transducer and activator of transcription 3: -56%, P<0.05), but higher suppressor of cytokine signaling 3 (+81%, P<0.05). Therefore, NIC exposure only during lactation programs rats for adipocyte hypertrophy in adult life, as well as for leptin and insulin resistance. Through the effects of NIC, perinatal maternal cigarette smoking may be responsible for the future development of some components of the metabolic syndrome in the offspring.

RESUMEN

OBJECTIVE: To determine whether motivational interviewing--a behavioural therapy for addictions-provided at home by specially trained midwives helps pregnant smokers to quit. DESIGN: Randomised controlled non-blinded trial analysed by intention to treat. SETTING: Clinics attached to two maternity hospitals in Glasgow. PARTICIPANTS: 762/1684 pregnant women who were regular smokers at antenatal booking: 351 in intervention group and 411 in control group. INTERVENTIONS: All women received standard health promotion information. Women in the intervention group were offered motivational interviewing at home. All interviews were recorded. MAIN OUTCOME MEASURES: Self reported smoking cessation verified by plasma or salivary cotinine concentration. RESULTS: 17/351 (4.8%) women in the intervention group stopped smoking (according to self report and serum cotinine concentration < 13.7 ng/ml) compared with 19/411(4.6%) in the control group. Fifteen (4.2%) women in the intervention group cut down (self report and cotinine concentration less than half that at booking) compared with 26 (6.3%) in the control group. Fewer women in the intervention group reported smoking more (18 (5.1%) v 44 (10.7%); relative risk 0.48, 95% confidence interval 0.28 to 0.81). Birth weight did not differ significantly (mean 3078 g v 3048 g). CONCLUSION: Good quality motivational interviewing did not significantly increase smoking cessation among pregnant women.

RESUMEN

BACKGROUND: Nicotine may be of therapeutic value in ulcerative colitis (UC), although its mechanism of action has not been established. OBJECTIVE: To examine the effect of a solution of nicotine on sustained resting pressure (tone) and contractile activity in the human colon. METHODS: Ten healthy volunteers, and seven with UC in symptomatic remission took part; all were non-smokers. All 17 subjects were given nicotine or placebo solution on two separate occasions in a randomized sequence. A water-perfused manometry catheter, with openings at 5, 10 and 15 cm from the tip, was placed by rigid sigmoidoscopy in the recto-sigmoid region. Baseline tone and activity were measured for 15 min prior to instillation of 20 ml of saline alone or with nicotine, 1.2 mg, at pH 4.5. Observations were made over the subsequent 15-20 min. RESULTS: Baseline spontaneous activity in all subjects showed both high- and low-frequency components; in three patients with UC, the low-frequency activity was of high amplitude. The nicotine reduced both tone and activity in all subjects, with reduction or abolition of the large contractions in UC. Tone in all 17 subjects was reduced significantly at 3 min after nicotine (P = 0.000015, sign test); the rate of recovery varied in individuals. Results from normals and UC did not differ significantly from each other. No significant change in tone or activity was observed with the saline solution. CONCLUSION: Intra-luminal nicotine significantly reduces both smooth muscle tone and contractile activity in the recto-sigmoid colon in both normal subjects and patients with UC.

RESUMEN

The findings obtained by the authors of the thesis submit the new cognitive values to the diagnosis of pathology of pregnancy i.e. the influence of nicotine on the organisms of a mother and a new-born child, estimated by the assay of cotinine, the most important metabolite of nicotine. The authors lay a particular stress on the "colostrum-milk way" in the mother-child relationship and this is that needs to be emphasized in this thesis.

RESUMEN

The findings presented by the authors of this report contribute to the diagnosis of pathology of pregnancy i.e. they assess the influence of nicotine on the organisms of a mother and a new-born child, estimated by concentration of cotinine, the most important metabolite of nicotine. The mean proportional share of cotinine in the fluids and organs in the pregnant women smoking actively was as follows: urine 72.1%, amniotic fluids 14.3%, colostrum 8.9% and placenta 4.7%. The authors pay a particular attention to the "colostrum-milk way" in the mother-child relationship what is emphasized in this report.

RESUMEN

Human remains from excavation sites in southern China, dated from 100 to 10,000 years, were investigated for nicotine. The nicotine concentrations were measured by radioimmunoassay. Consequently, the values measured represent the sum of nicotine and its metabolites. Positive results were observed in 25.9% (mean values of all samples). The concentrations ranged from 11.8 to 474.2 ng/g sample. From the excavation sites with the highest number of individuals, Chongtong (18 individuals) were 38.9%, and from the site Leigund (21 individuals) were 28.6% from the samples nicotine positive. The highest level with 474.2 ng/g nicotine was found in a sample dated 100 years. It is possible, that this individual was smoker. In addition the samples were investigated also by gas chromatography/mass spectrometry. The GC/MS indicated the presence of nicotine and its primary metabolite, cotinine. The presence of cotinine points out the assumption that nicotine was used antemortem. The detection of unchanged nicotine indicates that nicotine remained present in bones up centuries.
