Effect of hypnotic suggestion on cognition and craving in smokers.

Cigarette smoking remains an important public health concern, and novel smoking cessation interventions are needed. Craving for cigarettes is a well-established target for intervention. Recent research has identified cognitive processes associated with craving, such as attentional bias to smoking cues, as targets for intervention. One intervention that may be effective in reducing attentional bias is hypnotic suggestion. Using a counterbalanced within-subjects design in a sample of active smokers (N = 33), this laboratory study examined if hypnotic suggestion can modify attention, assessed by the classic and smoking Stroop tasks, and craving. Hypnotic susceptibility was assessed using the Stanford Scale of Hypnotic Susceptibility. There was no evidence that hypnotic susceptibility moderated the effect of hypnotic suggestion on the classic or smoking Stroop effects. However, hypnotic susceptibility did moderate the effect of hypnotic suggestion on craving, such that hypnotic suggestion reduced craving in individuals with high levels of susceptibility. Further research into the mechanisms by which hypnotic suggestion reduces craving is warranted.

Biobehavioral effects of baclofen in anxious alcohol-dependent individuals: a randomized, double-blind, placebo-controlled, laboratory study.

Baclofen has been suggested as a potential pharmacotherapy for alcohol use disorder, but the clinical data are conflicting. Here we investigated the biobehavioral effects of baclofen in a sample of anxious alcohol-dependent individuals. This was a randomized, double-blind, placebo-controlled, human laboratory study in non-treatment seeking alcohol-dependent individuals with high trait anxiety (N=34). Participants received baclofen (30 mg per day) or placebo for at least 8 days, then performed an experimental session consisting of alcohol cue-reactivity followed by alcohol administration procedure (alcohol priming, then alcohol self-administration). Total amount of alcohol self-administered was the primary outcome; alcohol craving, subjective/physiological responses and mood/anxiety symptoms were also evaluated. There was no significant medication effect on the total amount of alcohol consumed during the alcohol self-administration (P=0.76). Baclofen blunted the positive association between maximum breath alcohol concentration during priming and the amount of alcohol consumption (significant interaction, P=0.03). Ratings of feeling intoxicated were significantly higher in the baclofen group after consuming the priming drink (P=0.006). During the self-administration session, baclofen significantly increased ratings of feeling high (P=0.01) and intoxicated (P=0.01). A significant reduction in heart rate (P<0.001) and a trend-level increase in diastolic blood pressure (P=0.06) were also detected in the baclofen group during the alcohol laboratory session. In conclusion, baclofen was shown to affect subjective and physiological responses to alcohol drinking in anxious alcohol-dependent individuals. These results do not support an anti-craving or anti-reinforcing effect of baclofen, but rather suggest that baclofen may act as a substitution medication for alcohol use disorder.

Sucralfate in the prevention of treatment-induced diarrhea in patients receiving pelvic radiation therapy: A North Central Cancer Treatment Group phase III double-blind placebo-controlled trial.

PURPOSE: Randomized studies have suggested that sucralfate is effective in mitigating diarrhea during pelvic radiation therapy (RT). This North Central Cancer Treatment Group study was undertaken to confirm the antidiarrheal effect of sucralfate. Several other measures of bowel function were also assessed. PATIENTS AND METHODS: Patients receiving pelvic RT to a minimum of 45 Gy at 1.7 to 2.1 Gy/d were eligible for the study. Patients were assigned randomly, in double-blind fashion, to receive sucralfate (1.5 g orally every 6 hours) or an identical looking placebo during pelvic RT. RESULTS: One hundred twenty-three patients were randomly assigned and found assessable. Overall, there was no significant difference in patient characteristics between those receiving sucralfate and those receiving placebo. Moderate or worse diarrhea was observed in 53% of patients receiving sucralfate versus 41% of those receiving placebo. Compared with patients receiving placebo, more sucralfate-treated patients reported fecal incontinence (16% v 34%, respectively; P =. 04) and need for protective clothing (8% v 23%, respectively; P =. 04). The incidence and severity of nausea were worse among those taking sucralfate (P =.03). Analysis of patient-reported symptoms 10 to 12 months after RT showed a nonsignificant trend toward more problems in patients taking sucralfate than in those taking placebo (average, 2.3 v 1.9 problems, respectively; P =.34). CONCLUSION: Sucralfate did not decrease pelvic RT-related bowel toxicity by any of the end points measured and seems to have aggravated some gastrointestinal symptoms.

Accelerated hyperfractionation radiation therapy after lumpectomy and axillary lymph node dissection in patients with stage I or II breast cancer: pilot study.

PURPOSE: To prospectively assess tolerance to accelerated hyperfractionation radiation therapy in patients undergoing breast-conservation therapy and to exclude, with 90% confidence, a 20% or greater risk of an acute toxic reaction of at least grade 3 (severe). MATERIALS AND METHODS: Thirty-seven patients (aged 33-80 years) with evaluatable cases received 48 Gy in twice-daily 1.6-Gy fractions to the breast and regional lymph nodes (if three or more lymph nodes were involved) and a boost of 9.6 Gy in twice-daily 1.6-Gy fractions. Acute and late effects were scored by using the Radiation Therapy Oncology Group and European Organization for the Research and Treatment of Cancer radiation morbidity criteria. RESULTS: One patient developed a grade 3 acute skin toxic reaction and another grade 3 (continuous) acute edema. There have been no grade 4 (life-threatening) acute toxic reactions, local recurrences, or cancer- or treatment-related deaths. CONCLUSION: This breast-conservation accelerated hyperfractionation radiation therapy schedule is tolerable. Additional follow-up is necessary to determine long-term morbidity and cosmesis, and further study in a larger patient group is necessary to confirm efficacy.
