A single dose of 1.0 mCi/kg of 153Sm-EDTMP provided relief from pain associated with bone metastases. Pain relief was observed within 1 week of administration and persisted until at least week 16 in the majority of patients who responded.

Introduction Stress has been found to be a significant risk factor for cigarette smoking. Stress affects males and females differently, as does the use of smoking for stress reduction. Few studies have examined gender differences with the interrelation of perceived stress and smoking behaviors and nicotine related symptomatology. Our study investigates this association, as well as the influence of sociodemographic variables. Methods This is a retrospective analysis of 62 smokers (41 males, 21 females) enrolled in a smoking cessation study. At the screening visit sociodemographic information, smoking behaviors and survey measures were completed. These included the Perceived Stress Scale (PSS), Minnesota Nicotine Withdrawal Scale (MNWS), and others. Analyses were conducted using multiple linear regression models. Results PSS score was found to have a negative association with number of cigarettes smoked in males (slope -0.29 +/- 0.08; p = 0.0009) and females (slope -0.20 +/- 0.18; p = 0.26) with no difference in effect between genders (p =0.64). Linear regression of MNWS on PSS revealed a positive association for both males (slope 0.41 +/- 0.068; p < 0.0001) and females (slope 0.73 +/- 0.14; p < 0.0001). There was a significant difference in effect between genders (p = 0.04). Conclusions A strong positive association was observed between perceived stress and nicotine withdrawal symptomatology in smokers of both sexes, with a larger effect seen in women. These findings emphasize the importance of stress reduction in smokers, which may lead to fewer withdrawal symptoms and more effective smoking cessation.

Although extrahematopoietic dose-limiting toxicity was neither observed or predicted, suboptimal absorbed dose estimates suggested that further escalation of 131I-MAb CC49 would not be useful. Future studies should focus on the use of radionuclides with high energy beta emissions, such as yttrium 90, and on strategies to optimize access of antibody to target antigens.

Background and Aims In some clinical studies men and women have been found to differ in their ability to quit smoking, perhaps as a result of progesterone. The primary aim of this study was to provide a preliminary test of whether progesterone (PRO), compared with placebo (PBO), was more effective for smoking cessation in men and women. Design Pilot double‐blind, placebo‐controlled randomized clinical trial. Setting Minneapolis/St Paul metro area, Minnesota, USA. Participants A total of 216 participants were randomized, including 113 men (18–60 years; PRO = 56, PBO = 57) and 103 women (18–50 years, pre‐menopausal with self‐reported regular menstrual cycles; PRO = 51, PBO = 52). Intervention Participants were randomized (1 : 1 within sex group) to either PRO (200 mg twice daily) or PBO. Participants were assigned a quit date approximately 7 days after starting medication (luteal phase for women) and were followed for 12 weeks to assess relapse. Measurements The primary outcome was self‐reported 7‐day point prevalence abstinence (PPA) at week 4. Secondary outcomes included 7‐day PPA at weeks 8 and 12, prolonged abstinence, continuous abstinence, urine cotinine < 50 ng/ml, expired carbon monoxide ≤ 5 parts per million (p.p.m.) and days to relapse. Findings There was a significant difference in 7‐day PPA at week 4 among women [PRO: 18 (35.3%) versus PBO: 9 (17.3%), odds ratio (OR) = 2.61, 95% confidence interval (CI) = 1.04, 6.54, P = 0.041], but not among men [PRO: 13 (23.2%) versus PBO: 12 (21.1%), 1.13 (0.47, 2.76), P = 0.782]. There was some evidence that PRO delayed relapse in women (days to relapse; PRO: 20.5 ± 29.6 versus PBO: 14.3 ± 26.8, P = 0.03) but not in men (PRO: 13.4 ± 25.9 versus PBO: 13.3 ± 23.8, P = 0.69). Conclusions Oral micronized progesterone may aid smoking cessation in women.
