Motivation to quit smoking among relatives of lung cancer patients

Long non-coding RNA LINRIS is upregulated in non-small cell lung cancer and its silencing inhibits cell proliferation by suppressing microRNA-10a maturation

Long noncoding RNA LINRIS (LINC00920) is known to participate in colorectal cancer. This study aimed to explore the role of LINRIS in non-small cell lung cancer (NSCLC). NSCLC and adjacent non-tumor tissues were collected from 62 NSCLC patients. LINRIS expression was detected using real-time quantitative PCR (RT-qPCRs). The 62 NSCLC patients were monitored every month for 5 years to evaluate the role of LINRIS in predicting the prognosis of NSCLC. The effects of LINRIS silencing on microRNA-10a (miR-10a) precursor and mature miR-10a levels were assessed by RT-qPCR. Cell proliferation was measured using Cell Counting Kit-8 (CCK-8) assays. LINRIS expression was upregulated in NSCLC tissues. High LINRIS levels predicted poor survival of NSCLC patients. LINRIS were positively correlated with mature (miR-10a) levels but not miR-10a precursor. In NSCLC cells, LINRIS silencing showed no role in miR-10a precursor accumulation but downregulated mature miR10a level. Moreover, LINRIS silencing inhibited cell proliferation, while miR-10a overexpression increased cell proliferation and inhibited the role of LINRIS silencing. Overall, LINRIS silencing may inhibit NSCLC cell proliferation by suppressing miR-10a maturation.

Is diagnosis of type 2 diabetes a "teachable moment"? A qualitative study

AIMS

To explore the potential of type 2 diabetes diagnosis to be a "teachable moment".

METHODS

Semi-structured interviews were conducted with 23 participants (10 people with type 2 diabetes, 13 relatives of people with type 2 diabetes) in Scotland, UK. They explored cognitive, emotional and behavioural changes following diagnosis of type 2 diabetes in oneself or in a relative. Data were analysed using Framework approach.

RESULTS

Strong emotional responses are not always related to the occurrence of a teachable moment. Risk perception and outcome expectancy were found to be teachable moment factors for patients with type 2 diabetes and their offspring, but not their partners. Change in self-concept increases the likelihood of type 2 diabetes diagnosis to be a teachable moment for patients but not for relatives. In some cases, type 2 diabetes is perceived as incompatible with current roles thus hindering diabetes self-management. Relatives often engage in caring for patients and "policing" their behaviour but did not report perceived changes in social roles.

CONCLUSIONS

The study suggests that diagnosis of type 2 diabetes is a teachable moment for some patients and their relatives. These findings have implications for interventions to address diabetes self-management in patients and primary prevention in their relatives.

Lung cancer and family-centered patient concerns

BACKGROUND

The risk factors, diagnosis, management, and outcomes for lung cancer (LC) are a family experience. Genetic and environmental factors interact to predispose certain groups to LC, including family member, and the family or caregiving unit experiences the disease course as an interdependent group. This qualitative study examined the concerns and preferences of LC patients about incorporating family in addressing their lung cancer experiences and cancer risks.

METHODS

This project aims to identify concerns and preferences for addressing family history documentation, risk assessment, prevention, and follow-up issues for LC patients and their family. We held focus groups (FG) to discuss the format and timing of addressing these preferences and concerns. The qualitative data was analyzed using a grounded theory approach.

RESULTS

7 FG totaling 17 participants were conducted. The mean age was 64. All patients had advanced lung cancer. Participants included five males; nine African-Americans; three current, 11 former and three never smokers. Five participants had parents or grandparents with LC. Two had siblings with LC. Six themes were identified: (1) Varied journeys to LC diagnosis. (2) Mixed patient perceptions of cancer causation. (3) Limited documentation and utilization of family history. (4) Diverse attitudes toward smoking cessation. (5) A range of discussions about cancer risk, prevention, and screening. (6) Implications for implementation of family-centered cancer care and health promotion.

CONCLUSIONS

The diagnosis of LC, its management, and outcomes occur in the family context. The diagnosis represents a potential teachable moment with opportunity to reduce the risk of LC development or improve early detection in a population at higher risk of developing lung cancer. Lung cancer patients are interested in discussing risk factors, prevention, and diagnosis of lung cancer for their relatives.

Association of Smoking in the Home With Lung Cancer Worry, Perceived Risk, and Synergistic Risk

PURPOSE/OBJECTIVES

To examine the association of smoking in the home with lung cancer worry, perceived risk, and synergistic risk, controlling for sociodemographics, family history of lung cancer, and health-related self-concept. The hypothesis is that participants with smoking in the home would have higher scores for lung cancer worry, perceived risk, and synergistic risk.
.

DESIGN

Cross-sectional baseline survey. 
.

SETTING

Participants recruited from an outpatient clinic and pharmacy at University of Kentucky HealthCare, an academic medical center.
.

SAMPLE

515 homeowners from a larger randomized, controlled trial aimed at reducing exposure to radon and secondhand smoke (SHS).
.

METHODS

Homeowners were selected via quota sampling so that about half would have a smoker or smokers in the home.
.

MAIN RESEARCH VARIABLES

Lung cancer worry and perceived risk; perception of synergistic risk of radon and SHS exposure; demographics.
.

FINDINGS

Participants with smoking in the home had higher rates of lung cancer worry and perceived risk. In addition, those with less education and a family history of lung cancer and who were current smokers had higher lung cancer worry and perceived lung cancer risk scores. Predictors of perception of synergistic risk were marital status and health-related self-concept.
.

CONCLUSIONS

Homeowners with smoking in the home, less education, and a family history of lung cancer had greater lung cancer worry and perceived lung cancer risk. Lung cancer risk reduction interventions with vulnerable populations are needed. 
.

IMPLICATIONS FOR NURSING

Nurses are in a unique position to target high-risk populations and identify opportunities to create teachable moments to reduce environmental risks of radon and tobacco smoke exposure.

Barriers and facilitators to smoking cessation in a cancer context: A qualitative study of patient, family and professional views

Background

Continued smoking after cancer adversely affects quality of life and survival, but one fifth of cancer survivors still smoke. Despite its demands, cancer presents an opportunity for positive behaviour change. Smoking often occurs in social groups, therefore interventions which target families and individuals may be more successful. This qualitative study explored patients, family members and health professionals’ views and experiences of smoking and smoking cessation after cancer, in order to inform future interventions.

Methods

In-depth qualitative interviews (n = 67) with 29 patients, 14 family members and 24 health professionals. Data were analysed using the ‘Framework’ method.

Results

Few patients and family members had used National Health Service (NHS) smoking cessation services and more than half still smoked. Most recalled little ‘smoking-related’ discussion with clinicians but were receptive to talking openly. Clinicians revealed several barriers to discussion. Participants’ continued smoking was explained by the stress of diagnosis; desire to maintain personal control; and lack of connection between smoking, cancer and health.

Conclusions

A range of barriers to smoking cessation exist for patients and family members. These are insufficiently assessed and considered by clinicians. Interventions must be more effectively integrated into routine practice.

Predictors of the Perception of Smoking Health Risks in Smokers With or Without Schizophrenia

OBJECTIVE

This study sought to examine the predictors of health risk perception in smokers with or without schizophrenia.

METHODS

The health risk subscale from the Smoking Consequences Questionnaire was dichotomized and used to measure health risk perception in smokers with (n = 67) and without schizophrenia (n = 100). A backward stepwise logistic regression was conducted using variables associated at the bivariate level to determine multivariate predictors.

RESULTS

Overall, 62.5% of smokers without schizophrenia and 40.3% of smokers with schizophrenia completely recognize the health risks of smoking (p ≤ .01). Multivariate predictors for smokers without schizophrenia included: sex (Exp (B) = .3; p < .05), Smoking Consequences Questionnaire state enhancement (Exp (B) = .69; p < .01), and craving relief (Exp (B) = 1.8; p < .01). Among smokers with schizophrenia, predictors were education (Exp (B) = .7; p < .05), nicotine dependence (Exp (B) = .5; p < .01), motivation to quit (Exp (B) = 1.8; p < .01), and Smoking Consequences Questionnaire craving relief (Exp (B) = 1.8; p < .01).

CONCLUSIONS

There was overlap and differences between predictors in smokers with and without schizophrenia. Commonly used techniques for education on the health consequences of cigarettes may work in smokers with schizophrenia, but intervention efforts specifically tailored to smokers with schizophrenia might be more efficacious.

Treating Nicotine Dependence and Preventing Smoking Relapse in Cancer Patients

INTRODUCTION

Despite the well-documented harmful effects of smoking, many cancer patients continue to smoke. Smoking cessation is critical to address in this population given the associated increase in treatment toxicity, risk of second primary tumors, decrease in treatment response and higher disease-specific and all-cause mortality with continued smoking following a cancer diagnosis. This review seeks to summarize the latest recommendations and guidelines on smoking cessation treatment for patients diagnosed with cancer, and the evidence behind those recommendations.

AREAS COVERED

We reviewed the latest evidence for smoking cessation treatments for cancer patients and the clinical guidelines and recommendation available for oncologists and health care providers. The unique aspects of nicotine dependence among patients diagnosed with cancer, and key challenges and barriers that cancer survivors and health care providers experience when considering smoking cessation treatments, and available clinical resources, are also discussed. Lastly, the authors summarize future directions in the field of smoking cessation treatment for cancer patients.

EXPERT COMMENTARY

While there are areas of improvement in research of smoking cessation treatment for cancer patients, critical under-explored areas remain. Nonetheless, providers should adhere to the NCCN guidelines and offer a brief counseling intervention to motivate patients to quit smoking when appropriate resources are not available.

Receptivity and Preferences for Lifestyle Programs to Reduce Cancer Risk among Lung Cancer Family Members

Background

Lifestyle factors and genetic information has been found to contribute to the occurrence of lung cancer. This study assessed receptivity to participating in lifestyle programs to reduce cancer risk among unaffected lung cancer family members. We also explored demographic, medical, and psychosocial correlates of willingness to participate in lifestyle programs.

Methods

Family members who are part of a lung Cancer Family Registry were asked to fill out a survey assessing their receptivity to cancer risk reduction programs including preferences for an individual or family-based program.

Results

Of the 583 respondents, 85% were “Somewhat” or “Definitely” willing to participate in a lifestyle program. Among those receptive, about half (56%) preferred a family-based approach. Preferred programs included weight management (36%) and nutritional information (30%). Preferred delivery channels were Internet (45%) and mail-based (29%) programs. On multivariate analysis, those definitely/somewhat receptive reported greater exercise self-efficacy scores (p=0.025).

Conclusion

The majority of the sample was receptive to lifestyle programs that might decrease cancer risk. There was a large preference for family-based weight management and nutritional programs. Further research is indicated to determine how to best incorporate a family-based approach to lifestyle programs for cancer family members.

A Motivational, Gender-Sensitive Smoking Cessation Resource for Family Members of Patients With Lung Cancer

PURPOSE/OBJECTIVES

To gather feedback on an innovative gender-sensitive booklet that draws on emotional connections and relationship factors to motivate smoking cessation.

RESEARCH APPROACH

Qualitative, descriptive.

SETTING

Six provinces in Canada.

PARTICIPANTS

30 family members of patients with lung cancer who were currently smoking or had recently quit.

METHODOLOGIC APPROACH

Parallel booklets for women and men were developed using language and images to emphasize family relationships and gender considerations to motivate smoking cessation. Participants were provided with the women's and men's versions of the resource, and they were asked to review the gender-specific version of the booklet that was relevant to them. Semistructured telephone interviews were conducted, and transcriptions were analyzed for themes.

FINDINGS

Three themes were evident in the data, including "new perspectives.

CONCLUSIONS

A gender-sensitive approach that focuses on relationship factors represents an acceptable way to engage relatives of patients with lung cancer in discussions to support smoking cessation.

INTERPRETATION

Approaches to supporting smoking cessation among relatives of patients diagnosed with lung cancer should draw on positive relationship bonds and caring connections to motivate cessation.

Second-Hand Smoke As a Predictor of Smoking Cessation Among Lung Cancer Survivors

Purpose

Second-hand smoke (SHS; ie, exposure to smoking of friends and spouses in the household) reduces the likelihood of smoking cessation in noncancer populations. We assessed whether SHS is associated with cessation rates in lung cancer survivors.

Patients and Methods

Patients with lung cancer were recruited from Princess Margaret Cancer Centre, Toronto, ON, Canada. Multivariable logistic regression and Cox proportional hazard models evaluated the association of sociodemographics, clinicopathologic variables, and SHS with either smoking cessation or time to quitting.

Results

In all, 721 patients completed baseline and follow-up questionnaires with a mean follow-up time of 54 months. Of the 242 current smokers at diagnosis, 136 (56%) had quit 1 year after diagnosis. Exposure to smoking at home (adjusted odds ratio [aOR], 6.18; 95% CI, 2.83 to 13.5; P < .001), spousal smoking (aOR, 6.01; 95% CI, 2.63 to 13.8; P < .001), and peer smoking (aOR, 2.49; 95% CI, 1.33 to 4.66; P = .0043) were each associated with decreased rates of cessation. Individuals exposed to smoking in all three settings had the lowest chances of quitting (aOR, 9.57; 95% CI, 2.50 to 36.64; P < .001). Results were similar in time-to-quitting analysis, in which 68% of patients who eventually quit did so within 6 months after cancer diagnosis. Subgroup analysis revealed similar associations across early- and late-stage patients and between sexes.

Conclusion

SHS is an important factor associated with smoking cessation in lung cancer survivors of all stages and should be a key consideration when developing smoking cessation programs for patients with lung cancer.

Guilt, censure, and concealment of active smoking status among cancer patients and family members after diagnosis: a nationwide study

OBJECTIVES

We aimed to identify the prevalence of feelings of guilt, censure, and concealment of smoking status among cancer patients and their family members who continued to smoke after the patient's diagnosis.

METHODS

Among 990 patient-family member dyads, 45 patients and 173 family members who continued to smoke for at least 1 month after the patients' diagnoses were administered questions examining feelings of guilt, censure, and smoking concealment.

RESULTS

Most patients who continued to smoke reported experiencing feelings of guilt toward their families (75.6%) and censure from their family members (77.8%), and many concealed their smoking from their family members (44.4%) or healthcare professionals (46.7%). Family members who continued to smoke also reported feelings of guilt with respect to the patient (63.6%) and that the patient was critical of them (68.9%), and many concealed their smoking from the patient (28.5%) or healthcare professionals (9.3%). Patients' feeling of guilt was associated with concealment of smoking from family members (55.9% vs. 10.0%) or health care professionals (55.9% vs. 20.0%). Family members who reported feeling guilty (36.5% vs. 16.3%) or censured (34.5% vs. 16.7%) were more likely to conceal smoking from patients.

CONCLUSION

Many patients and family members continue to smoke following cancer diagnosis, and the majority of them experience feelings of guilt and censure, which can lead to the concealment of smoking status from families or health care professionals. Feelings of guilt, censure, and concealment of smoking should be considered in the development and implementation of smoking cessation programs for cancer patients and family members.

Perceived risk and quitting behaviors: results from the ITC 4-country survey

OBJECTIVE

To rigorously test the relation between perceived risk (i.e., belief about the likelihood of harm) and quitting smoking.

METHODS

Data from a longitudinal study with a nonrestrictive sample of smokers (N = 4307) from the United States, Canada, the United Kingdom, and Australia were examined to predict quitting behaviors at 8-12 months.

RESULTS

Perceived risk predicted plans to quit, quit attempts, and, to some extent, sustained quitting. The relation was stronger for relatively simple (e.g., plans to quit) than for complex behaviors (e.g., sustained quitting).

CONCLUSION

Perceived risk plays a significant role in predicting quitting smoking, more so for relatively simple behaviors.
