Lifestyle change in the cancer setting using 'the teachable moment': protocol for a proof-of-concept pilot in a urology service

Nutrient Intakes in Prostate Cancer Survivors in the United States: A Nationally Representative Study

There are currently more than 3.3 million prostate cancer (PC) survivors in the United States. Conformance with national dietary guidelines and a good diet quality may lower the risk for Gleason grade progression in PC patients. Assessing the nutritional status of PC survivors is thus of paramount importance from a public health nutrition perspective. We used 24-h dietary recall data from the National Health and Nutrition Examination Surveys (NHANES) to systematically estimate nutrient intakes in n = 360 PC survivors (which may be extrapolated to represent n = 1,841,030 PC survivors) aged 70.69 years on average, and contrasted the results to the daily nutritional goals (DNG) in the 2020-2025 Dietary Guidelines for Americans (DGA). Diet quality in PC survivors was found to be generally poor, and the DNG as specified in the DGA were not met for many micronutrients, including calcium, magnesium and potassium. PC survivors had an insufficient intake of many vitamins (including vitamins A, C, D and E), and did not meet the intake recommendations for dietary fiber. Racial disparities in PC were reflected in the lower overall DQ in Non-Hispanic Black participants. Our results reiterate the need for nutritional assessment and counseling to improve DQ in PC patients.

Tobacco use in patients with ENT tumours: Deficits in the provision of education and smoking cessation support

PURPOSE

Smoking is not only one of the main risk factors for the development of most malignant and numerous benign ENT tumours but also has an important influence on therapy and prognosis. Even quitting smoking at the time of diagnosis significantly reduces mortality. Patients have a particularly strong desire to stop smoking when they are diagnosed. The present study investigated to what extent patients were aware of the relationships between smoking and the development and prognosis of tumours and how much information and smoking cessation support they were offered by physicians.

METHODS

A total of 194 patients (74.7% male, 62.0 ±10.6 a) with malignant primary ENT tumours, pre-cancerous tumours, Reinke's oedema and salivary gland tumours were interviewed.

RESULTS

22.7% were nonsmokers, 49.5% were cigarette smokers and 27.8% were ex-smokers. A total of 57.0% of the smokers said they would have quit before the onset of the disease if they had known about the association. Forty-one percent did not receive information about the association between smoking and the development of their disease, while 45.5% did not receive information about the relationship with their prognosis. The provision of information lasted less than 5 min for 40.4% of the patients and more than 10 min for only 13.5%. In total, 50.7% of the patients were directly requested not to smoke. A total of 7.7% received offers of smoking cessation support from otolaryngologists and 18.2% received such offers from family physicians.

CONCLUSIONS

There is a pronounced need for improvements in the provision of medical information about the health risks associated with smoking and offers to support patient efforts to stop smoking. In particular, the appointment during which the diagnosis is communicated to the patient should be considered a 'teachable moment' that can lead to smoking cessation.

Evaluating the potential impact of lifestyle-based behavior change interventions delivered at the time of colorectal cancer screening

PURPOSE

To analyze interventions implemented at the time of colorectal cancer (CRC) screening, or among individuals who have previously undergone investigation for CRC, focused on reducing CRC risk through promotion of lifestyle behavior change. Additionally, this review evaluated to what extent such interventions apply behavior change techniques (BCTs) to achieve their objectives.

METHODS

Five databases were systematically searched to identify randomized control trials seeking to reduce CRC risk through behavior change. Outcomes were changes in health-related lifestyle behaviors associated with CRC risk, including changes in dietary habits, body mass index, smoking behaviors, alcohol consumption, and physical activity. Standardized mean differences (SMDs) with 95% confidence intervals (CIs) were pooled using random effects models. BCT's were coded from a published taxonomy of 93 techniques.

RESULTS

Ten RCT's met the inclusion criteria. Greater increase in fruit/vegetable consumption in the intervention group were observed with respect to the control (SMD 0.13, 95% CI 0.08 to 0.18; p < 0.001). Across fiber, alcohol, fat, red meat, and multivitamin consumption, and smoking behaviors, similar positive outcomes were observed (SMD 0.09-0.57 for all, p < 0.01). However, among physical activity and body mass index, no difference between the intervention groups compared with controls were observed. A median of 7.5 BCTs were applied across included interventions.

CONCLUSION

While magnitude of the observed effect sizes varied, they correspond to potentially important changes in lifestyle behaviors when considered on a population scale. Future interventions should identify avenues to maximize long-term engagement to promote sustained lifestyle behavior change.

Gender Differences in Factors Associated with Clinically Meaningful Weight Loss among Adults Who Were Overweight or Obese: A Population-Based Cohort Study

OBJECTIVES

The impact of heterogeneity on gender difference for achieving clinically meaningful weight loss (cmWL) remains unclear. Here, we explored the potential gender differences in factors associated with cmWL.

METHODS

A total of 60,668 participants with body mass index (BMI) ≥25 kg/m2 at study entry and available BMI values at follow-up were included in this study. cmWL was defined as a weight loss of ≥5% from the study entry to follow-up. The associations of social-demographic factors, personal history of chronic diseases, lifestyle behaviors, and history of BMI with cmWL were evaluated using logistic regression models.

RESULTS

During a median follow-up of 9.13 years, 26.6% of the participants had a cmWL (30.8% for females vs. 23.1% in males; p < 0.001). Participants with older age, obesity at study entry, being more physical activity compared to 10 years ago, being relapsed smokers or consistent current smokers, having a history of chronic diseases (i.e., diabetes, osteoporosis, and stroke), cancer diagnosis during the study period, and more than 10-year follow-up were more likely to achieve cmWL in both males and females (all p < 0.05). The new smoking quitters and participants with less active in physical activity compared to 10 years ago were less likely to achieve cmWL in both males and females (all p < 0.05). Specifically, males with a history of emphysema were more likely to reach cmWL, and for females, those being overweight at 20 years old and current drinkers were more likely to reach cmWL (p < 0.05). Sensitivity analyses demonstrated similar results.

CONCLUSION

Age, BMI status, physical activity, smoking status, family income, and health status were independent factors in males and females for weight management. However, further well-designed prospective studies are warranted to confirm our findings.

Dietary interventions for cancer survivors

This review evaluates evidence on dietary interventions for cancer survivors giving an overview of people's views and preferences for service attributes and provides a narrative review. After cancer, people often want to change their diet and there is a plethora of evidence why dietary optimisation would be beneficial. However, cancer survivors have different preferences about attributes of services including: place, person and communication mode. Randomised control trials have been reviewed to provide a narrative summary of evidence of dietary interventions. Most studies were on survivors of breast cancer, with a few on colorectal, prostate and gynaecological survivors. Telephone interventions were the most frequently reported means of providing advice and dietitians were most likely to communicate advice. Dietary assessment methods used were FFQ, food diaries and 24-h recalls. Dietary interventions were shown to increase intake of fruit and vegetables, dietary fibre, and improve diet quality in some studies but with contradictory findings in others. Telephone advice increased fruit and vegetable intake primarily in women with breast cancer and at some time points in people after colorectal cancer, but findings were inconsistent. Findings from mail interventions were contradictory, although diet quality improved in some studies. Web-based and group sessions had limited benefits. There is some evidence that dietary interventions improve diet quality and some aspects of nutritional intake in cancer survivors. However, due to contradictory findings between studies and cancer sites, short term follow-up and surrogate endpoints it is difficult to decipher the evidence base.

Knowledge of smoking as a risk factor for disease among urology clinic patients in Australia

INTRODUCTION

Smoking remains a common habit among the general population. Despite the well-established risks of smoking, relatively few studies have been undertaken to assess the understanding of these risks among the general population. We intended to assess the understanding of smoking as a risk factor for various conditions in a urology outpatient cohort to assess the level of knowledge as well as particular strengths and weaknesses they possess.

METHODS

A four-page questionnaire was distributed among urology outpatients over a 5 month period. The questionnaire captured information regarding the knowledge of smoking as a risk factor for various urological and non-urological conditions. Results were collated and stratified according to patient's cancer history as well as smoking status.

RESULTS

A total of 112 participants were included in our analytical sample. Our study demonstrated a deficiency in knowledge regarding smoking and urological conditions. When ranked by level of knowledge, four of the bottom five conditions were urological in nature. Furthermore, we found that patients with a personal cancer history demonstrated generally poorer knowledge of smoking as a risk factor compared to patients without a cancer history. Conversely, smokers themselves demonstrated a greater understanding of risks compared to non-smokers.

CONCLUSIONS

Our study suggests there is much work to be done in the education of patients on the risks of smoking from a urological point of view. We believe more initiative needs to be taken by the specialists treating such patients to achieve an improved level of knowledge.

What do patients with urothelial cancer know about the association of their tumor disease with smoking habits? Results of a German survey study

Purpose

Smoking represents a primary risk factor for the development of urothelial carcinoma (UC) and a relevant factor impacting UC-specific prognosis. Data on the accordant knowledge of UC-patients in this regard and the significance of physicians in the education of UC-patients is limited.

Materials and Methods

Eighty-eight UC-patients were enrolled in a 23-items-survey-study aimed to analyse patient knowledge and awareness of their tumor disease with smoking along with physician smoking cessation counselling.

Results

The median age of the study patients was 69 years; 26.1% (n=23), 46.6% (n=41), and 27.3% (n=24), respectively, were non-smokers, previous, and active smokers. Exactly 50% of active smokers reported a previous communication with a physician about the association of smoking and their tumor disease; however, only 25.0% were aware of smoking as main risk factor for UC development. Merely 33% of the active smokers had been prompted directly by their physicians to quit smoking. About 42% of active smokers had received the information that maintaining smoking could result in a tumor-specific impairment of their prognosis. Closely 29% of active and about 5% of previous smokers (during the time-period of active smoking) had been offered support from physicians for smoking cessation. No association was found between smoking anamnesis (p=0.574) and pack-years (p=0.912), respectively, and tumor stage of UC.

Conclusions

The results of this study suggest that the medical conversation of physicians with UC-patients about the adverse significance of smoking is limited. Implementation of structured educational programs for smoking cessation may be an opportunity to further enhance comprehensive cancer care.
