Smoking and Drinking Behavior in Patients with Head and Neck Cancer: Effects of Behavioral Self-Blame and Perceived Control 总被引:4,自引:0,他引:4
Christensen AJ Moran PJ Ehlers SL Raichle K Karnell L Funk G 《Journal of behavioral medicine》1999,22(5):407-418
Patients who continue to use tobacco or alcohol following treatment for head and neck cancers are at greater risk for cancer recurrence and mortality. The present study examined the effects of behavioral self-blame and perceived control over health on smoking and alcohol use in a sample of 55 patients with cancers of the head and neck. Measures of self-blame, perceived control, and depression were administered and an assessment of past and current smoking and drinking behavior was obtained. As anticipated, continued smoking after completion of oncologic treatment was predicted by the interaction of behavior specific self-blame and perceived control. Patients who attributed the cause of their cancer to their past substance use exhibited a lower likelihood of smoking only if they also held the expectancy that their future cancer-related health was contingent on their own behavior. Among patients not holding the belief that cancer recurrence was contingent on their own actions, self-blame was associated with a higher probability of continued smoking. Self-blame and perceived control had no effect on continued alcohol use. 相似文献

Comorbidity measurements have recently been used to improve estimation of tolerance to allogeneic hematopoietic cell transplantation (HCT). We sought to determine the independent effect of comorbidity and performance status on HCT outcome and to devise a simple risk classification system for transplant-related mortality. We analyzed 105 consecutively enrolled patients who underwent HCT and received reduced intensity conditioning with fludarabine, melphalan, and alemtuzumab. Comorbid conditions were tabulated using 2 scales, the Charlson Comorbidity Index (CCI) and the Kaplan-Feinstein Scale (KFS). Comorbid conditions were found in 47% of patients by the KFS and in 27% by the CCI (P < .001). Using the Eastern Cooperative Oncology Group Performance Status (PS) scale, 34% had a PS score >0 (range, 0-2). A simple scale combining the KFS and PS enabled separation of high- from low-risk patients, with 6-month cumulative incidences 50% and 15%, respectively for transplant-related mortality (P = .001) and enhanced prognostic power over the CCI alone (P = .018). Prospective studies evaluating more comprehensive functional and comorbidity measurements are warranted. 相似文献

Murine model of pulmonary anthrax: kinetics of dissemination, histopathology, and mouse strain susceptibility 下载免费PDF全文
Lyons CR Lovchik J Hutt J Lipscomb MF Wang E Heninger S Berliba L Garrison K 《Infection and immunity》2004,72(8):4801-4809
Bioweapons are most often designed for delivery to the lung, although this route is not the usual portal of entry for many of the pathogens in the natural environment. Vaccines and therapeutics that are efficacious for natural routes of infection may not be effective against the pulmonary route. Pulmonary models are needed to investigate the importance of specific bacterial genes in virulence, to identify components of the host immune system that are important in providing innate and acquired protection, and for testing diagnostic and therapeutic strategies. This report describes the characteristics of host and Bacillus anthracis interactions in a murine pulmonary-infection model. The infective dose varied depending on the route and method of inoculation. The germination process in the lung began within 1 h of inoculation into the lung, although growth within the lung was limited. B. anthracis was found in the lung-associated lymph nodes approximately 5 h after infection. Minimal pneumonitis was associated with the lung infection, but significant systemic pathology was noted after dissemination. Infected mice typically succumbed to infection approximately 3 to 4 days after inoculation. The 50% lethal doses differed among inbred strains of mice, but within a given mouse strain, neither the age nor the sex of the mice influenced susceptibility to B. anthracis. 相似文献

Temperament as a potential predictor of mortality: Evidence from a 41-year prospective study 总被引:3,自引:0,他引:3

Psychological factors were hypothesized to influence mortality, in particular, early versus later mortality. To explore the relationship between temperament, a psychological factor, and mortality in a prospective study of 1337 medical students, we constructed a measure portraying three temperament types, using latent class analysis. Death occurred in 113 subjects over 25–41 years of follow-up. In univariate survival analysis, subjects tending to direct tension inward when under stress (Tension-In) had a higher risk of mortality than Tension-Out or Stable types. These associations persisted after adjustment for age, smoking, cholesterol level, and Quetelet Index. The relative risk (RR) of mortality for Tension-In was 1.56 (95% confidence interval, 1.00–2.44) compared with the Stable group. The risk was due entirely to the excess risk in persons under 55 years of age (RR, 2.59; 95% confidence interval, 1.46–4.62); the corresponding risk of death in older persons was 0.66 (0.30–1.48). Thus temperament is a significant risk factor for mortality, in particular, premature death. 相似文献

Factors influencing help seeking in mentally distressed young adults: a cross-sectional survey. 下载免费PDF全文

BACKGROUND: Young adults, especially men, are among those least likely to consult healthcare professionals when mentally distressed or suicidal. AIMS: To investigate the help-seeking behaviours of mentally distressed young adults. Design of study: Cross-sectional survey. SETTING: Bristol and surrounding areas, including inner-city, suburban and urban locations. METHOD: A questionnaire was sent to a sample of 3004 young adults aged 16-24 years. This assessed probable mental disorder (using the 12-item general health questionnaire [GHQ-12]), suicidal thoughts (GHQ-28 suicide subscale), and help-seeking behaviours. RESULTS: Most responders who were assessed as having probable mental disorders (GHQ "cases") had not sought help. Help seeking was more common in female GHQ cases than male cases (34.8% and 21.8%,respectively; P = 0.003) and women with suicidal thoughts more commonly sought help than men with suicidal thoughts (41.6% and 30.9%, respectively; P = 0.15). Small proportions of male and female GHQ cases (7.5% and 8.9%, respectively; P = 0.6), and less than one in five responders with suicidal thoughts, had consulted a general practitioner. In more female than male cases, help was sought from family and friends (30.7% and 18.4%, respectively; P = 0.004). GHQ score was the strongest predictor of help seeking. Men had a higher threshold of severity at which they would seek help than women. Recent experience of suicidal thoughts appeared to be a stronger predictor of formal help seeking in mentally distressed women than mentally distressed men. CONCLUSION: Distressed young adults are reluctant to seek help. Men are particularly unlikely to do so unless severely distressed and tend not to seek lay support. Sex differences in help seeking may be important in understanding the high suicide rate for men. 相似文献

In many human lung adenocarcinoma cell lines, a pathway involving epidermal growth factor receptor (EGFR), ErbB2 and ErbB3 receptors, phosphatidyl inositol 3-kinase (PI3K), Akt, glycogen synthase kinase 3-beta (GSK3-beta), and cyclin D1 controls cell growth, survival, and invasiveness. We have investigated this pathway in paired transformed/nontransformed cell lines from murine peripheral lung epithelium, E9/E10 and A5/C10. The E9 and A5 carcinoma lines expressed ErbB3 and transforming growth factor-alpha (TGF-alpha) and responded to TGF-alpha stimulation with protein complex formation including the p85 regulatory subunit of PI3K, activation of Akt, phosphorylation of GSK3-beta, and increased cyclin D1 protein and the cell cycle. ErbB3 and TGF-alpha were not detected in the nontransformed E10 and C10 cell lines. Nevertheless, exposure of E10 or C10 cells to TGF-alpha activated PI3K and Akt and increased cyclin D1 and cell growth. The effector pathway from the EGFR to PI3K in these nontransformed cells included the adaptor Grb2, the docking protein Gab1, and the phosphatase Shp2. Gab1 was highly expressed in E10 and C10 cells but not in the malignant E9 and A5 sister lines. Complexes of EGFR/Grb2/Gab1/Shp2 after TGF-alpha stimulation were prominent only in E10 and C10 cells. Thus, alternate pathways downstream of EGFR regulate mitosis in these paired malignant versus nontransformed lung cell lines. 相似文献
