Nicotine dependence treatment for patients with cancer

Abstract

A semifluidized bed was proposed to allay bed plugging during the filtration of fines‐hydrocarbon suspensions. Mitigation of plugging was allowed by alternating semifluidization during capture with unconstrained fluidization for removal of deposits. Solids holdup conditions were established to prevent deposition in the fluidization section. The cyclic parameters were varied to allow efficient removal of deposits during washing. Analysis with a filtration model accounting for solids detachment in the fixed bed section revealed that the fluidization section favored growth of aggregate size entering the fixed bed. Analysis of the split ratios between fixed and fluidized bed heights revealed that the shallowest fluidization sections delayed deposition in the fixed bed. In cyclic operation, reversibility of the semifluidized bed was best recovered via gas injection during the washing stages. However, the filtration times in successive cycles shortened with increasing washing times but lengthened with increasing the washing superficial suspension velocity. © 2008 American Institute of Chemical Engineers AIChE J, 2008

Smoking Cessation and Lung Cancer: Oncology Nurses Can Make a Difference

“…Estimates for the prevalence of smoking have ranged from 24% to 60% among newly diagnosed lung cancer patients as compared to 12% to 29% among the general United States population [5][6][7] . Although the diagnosis of lung cancer presents a compelling reason to quit smoking, studies have estimated that between 8% to 17% of smokers continue to smoke after the diagnosis 5,6 . This finding underscores the highly addictive nature of tobacco dependence and the importance of assessing smoking status at diagnosis and incorporating smoking cessation interventions into clinical care.…”

“…Laryngectomized patients due to cancer treatment have a two-fold probability of smoking abstinence than those treated with radiotherapy only 3 .…”

“…Patient should be encouraged to quit smoking at each medical consultation. Other smokers in the family must also be counseled not to smoke 3 . According to Jain (2003) 13 , gradual reduction or quit attempts to smoking cessation show the same probability of success.…”

“…It is known that smoking is related to at least 30% of cancer deaths. It is a risk factor for the onset of lung, mouth, pharynx, larynx, esophagus, stomach, pancreas, uterine cervix, kidney and bladder carcinomas 3 . Moreover, morbidity by cardiovascular and cerebrovascular diseases, chronic obstructive pulmonary diseases (COPD) and peptic diseases, as well as other affections, is higher among smokers 1 .…”

“…This may involve increasing positive health behaviors such as healthy diet, exercise, and medication adherence as well as eliminating negative behaviors such as tobacco use. Strikingly some studies report that more than half of diagnosed cancer patients continue to smoke after cancer treatment [22]. Although there is a well-established literature identifying attitudinal processes associated with the maintenance and cessation of cigarette smoking in healthy populations, less is known about the predictors of continued smoking and plans for quitting smoking among diagnosed cancer patients, and even less is known about these associations in developing countries.…”
