Changes in lifestyle among prostate cancer survivors: A nationwide population-based study

Antineoplastics for treating Alzheimer's disease and dementia: Evidence from preclinical and observational studies

As the world population ages, there will be an increasing need for effective therapies for aging-associated neurodegenerative disorders, which remain untreatable. Dementia due to Alzheimer's disease (AD) is one of the leading neurological diseases in the aging population. Current therapeutic approaches to treat this disorder are solely symptomatic, making the need for new molecular entities acting on the causes of the disease extremely urgent. One of the potential solutions is to use compounds that are already in the market. The structures have known pharmacokinetics, pharmacodynamics, toxicity profiles, and patient data available in several countries. Several drugs have been used successfully to treat diseases different from their original purposes, such as autoimmunity and peripheral inflammation. Herein, we divulge the repurposing of drugs in the area of neurodegenerative diseases, focusing on the therapeutic potential of antineoplastics to treat dementia due to AD and dementia. We briefly touch upon the shared pathological mechanism between AD and cancer and drug repurposing strategies, with a focus on artificial intelligence. Next, we bring out the current status of research on the development of drugs, provide supporting evidence from retrospective, clinical, and preclinical studies on antineoplastic use, and bring in new areas, such as repurposing drugs for the prion-like spreading of pathologies in treating AD.

Associations of role, area deprivation index, and race with health behaviors and body mass index among localized prostate cancer patients and their partners

PURPOSE

To examine the associations of role (localized prostate cancer (PCa) patient vs. their intimate partner), area deprivation index (ADI-higher scores indicating higher neighborhood deprivation levels), and race (Black/African American (AA) vs. White) with health behaviors and body mass index (BMI) among PCa patients and partners. The behaviors include smoking, alcohol consumption, diet quality, sedentary behaviors, and physical activity (PA).

METHODS

This study used the baseline data collected in a clinical trial. Given the nested structure of the dyadic data, multi-level models were used.

RESULTS

Significant role-race interaction effects on smoking, ADI-race effects on alcohol consumption, and role-ADI effects on BMI were found. Meanwhile, patients smoked more cigarettes, decreased alcohol consumption, had less healthful diets, spent longer time watching TV, did fewer sedentary hobbies, had more confidence in PA, and had higher BMIs than their partners. High ADI was independently associated with lower odds of drinking alcohol, using computer/Internet, and doing non-walking PA, and higher BMI compared to low ADI controlling for role and race. Black/AA dyads had less smoking amount and alcohol consumption and higher sedentary time and BMI than White dyads when adjusted for role and ADI.

CONCLUSIONS

This study identified significant interaction and main effects of role, ADI, or race on health behaviors and BMI.

IMPLICATIONS FOR CANCER SURVIVORS

Future behavioral interventions should address divergent individual needs between patients and partners, social and neighborhood barriers, and cultural indicators of racial groups to promote healthful behaviors and improve the quality of survivorship for PCa patients and partners.

The Risk of Cancer-Associated and Radiotherapy-Associated Cardiovascular Diseases among Patients with Breast Cancer

BACKGROUND

The cardio-related issues should be emphasized as the survival rates of breast cancer increased. We investigated the risk of coronary artery disease (CAD) and stroke due to breast cancer or radiotherapy.

METHODS

In this retrospective cohort study, breast cancer patients diagnosed between 2007 and 2016 were recruited from Taiwan Cancer Registry Database and were followed until the end of 2018 by linking with the Taiwan National Health Insurance Database. The general population was randomly selected from the whole population in 2007. Standardized incidence ratios (SIR) were calculated to compare the risk of CAD and stroke between patients and the general population. Within the cohort, we included the patients diagnosed between 2011 and 2016. Cox proportional hazards model and subdistribution hazard function were used to investigate the associations of radiotherapy with the risk of CAD and stroke.

RESULTS

Overall SIR of CAD was 0.82 (95% confidence interval [CI]: 0.78-0.86), while were 1.43 and 1.08 (95% CI: 1.30-1.55 and 1.00-1.16) 1 and 2 years after diagnosis, respectively. Overall SIR of stroke was 0.63 (95% CI: 0.60-0.67), the results were similar after considering the time since diagnosis. The adjusted hazard ratios (HR) for the associations of radiotherapy with CAD and stroke risk were 0.91 (95% [CI] = 0.76-1.09) and 0.84 (95% CI = 0.68-1.04), respectively. The results were similar by using subdistribution hazard function.

CONCLUSIONS

The risk of CAD was higher within the first 2 years of breast cancer diagnosis. We found no association between radiotherapy and the risk of CAD and stroke.

Case studies on psychosocial factors that help make exercise programmes for prostate cancer patients self-sustaining

OBJECTIVES

Patients with prostate cancer (PCa) benefit from regular exercise, but it is difficult for patients to maintain an exercise regime. We examined two exercise programmes that have proven to be self-sustaining with the goal of identifying features they share that may contribute to their success.

METHODS

We compared the FC Prostata football (soccer) league in Denmark and the 'Butts in a Boat' (BIAB) dragon-boating team in Canada. The FC Prostata Project Coordinator and the BIAB team leaders provided information on their programmes' history and structure.

RESULTS

Both programmes are team-based with regularly scheduled intense exercise at their core. In both cases, social activities evolved spontaneously, starting with the men going out for food and/or drinks after practices. The sustainability of these programmes may be driven by the regular socialisation linked to the fitness activities.

CONCLUSIONS

Our case studies suggest that exercise programmes for PCa patients may have a good chance of being self-sustaining, if they are: (1) centred around intense exercise, (2) of a team nature, (3) structured to promote egalitarianism and avoid one-on-one competition within teams, yet (4) have some competitions between teams. The data suggest that informal social activities organised by patients after team practices may be important for building fellowship and strengthening patients' commitment to exercise both for themselves and for their team members.

Development of healthy lifestyle consciousness index for gynecological cancer patients

PURPOSE

Healthy lifestyle is related to quality of life (QOL) after cancer diagnosis and prognosis. However, there are few reports on patients conscious of healthy lifestyle and patients requiring medical providers' attention regarding healthy lifestyle. We aimed to develop a healthy lifestyle consciousness index (HLCI) for cancer patients and evaluated its validity in gynecological cancer patients.

METHODS

The HLCI was designed to assess degree of healthy lifestyle consciousness, including items regarding "diet," "exercise," "body weight," and "sleep." Exploratory factor analysis was performed for dimensionality of the scale; Cronbach's alpha was calculated to assess internal-consistency reliability. For criterion-based validity, we calculated proportions of stage III/IV gynecological malignancies in those with categorized HLCI scores based on tertiles. Concurrent validity was evaluated between HLCI and other quality of life (QOL) scales including European Organization for Research and Treatment of Cancer QLQ-C30 in limited patients.

RESULTS

HLCI comprised five 10-point items (0-45); higher values implied improved healthy lifestyle consciousness. Data from 108 gynecological malignancy patients at Kyoto University Hospital were analyzed. The mean age of subjects was 55.8 years; 36.1% of them had uterine corpus cancer; 34.3% were at stage III/IV of gynecological malignancy. The factor analysis revealed HLCI was unidimensional; the reliability based on Cronbach's alpha was satisfactory (0.88). The proportions of stage III/IV gynecological malignancies were 25.7%, 33.3%, and 44.4% in those with first (7-24 points), second (25-30 points), and third (31-46 points) tertiles of HLCI score, respectively. For patients with other QOL scales (n = 25), the mean scores of global health status of QLQ-C30 were 33.3, 50.0, and 83.3 for first, second, and third tertiles of HLCI score, respectively.

CONCLUSION

HLCI was successfully validated; thus, patients with advanced stages or higher QOL might have strong consciousness regarding healthy lifestyle. HLCI may be useful in precision care for improved lifestyles and QOL.

Psychosocial Determinants of Lifestyle Change after a Cancer Diagnosis: A Systematic Review of the Literature

Simple Summary

Although cancer survivors may experience health benefits from favorable lifestyle changes, many cancer survivors do not adhere to lifestyle recommendations or make favorable lifestyle changes after cancer diagnosis. This systematic review of the literature aimed to provide an overview of the scientific literature on sociodemographic, psychological and social determinants that may facilitate or hamper lifestyle change after the diagnosis cancer. It provides a structured overview of the large variety of determinants of changes in different lifestyle behaviors (physical activity, diet, smoking, alcohol, sun protection, and multiple lifestyle behaviors) derived from the 123 included papers (71 quantitative and 52 qualitative). Findings demonstrate the important role of oncology healthcare professionals in promoting healthy lifestyle changes in cancer survivors and inform researchers and healthcare professionals about the methods and strategies they can use to promote healthy lifestyle changes in cancer survivors.

Abstract

The aim of this study is to provide a systematic overview of the scientific literature on sociodemographic, psychological and social determinants that may facilitate or hamper lifestyle change after the diagnosis cancer. Four databases (PubMed, PsychINFO, Cumulative Index to Nursing and Allied Health Literature (CINAHL), and Web of Science) were searched for relevant papers up to October 2021. Of the 9586 references yielded by the literature search, 123 papers were included: 71 quantitative and 52 qualitative papers. Findings showed a large variety of determinants influencing lifestyle change after cancer diagnosis, with differences between lifestyle behaviors (physical activity, diet, smoking, alcohol, sun protection, and multiple lifestyle behaviors) and findings from quantitative vs. qualitative studies. Findings demonstrate the important role of oncology healthcare professionals in promoting healthy lifestyle changes in cancer survivors. In addition, findings inform researchers involved in the development of health promotion programs about the methods and strategies they can use to promote healthy lifestyle changes in cancer survivors. Favorable lifestyle changes are expected to have beneficial effects on cancer risk and overall health in cancer survivors.

Changes in lifestyle among prostate cancer survivors: A nationwide population-based study

Objective

Long‐term information on lifestyle changes among prostate survivors is lacking. In this nationwide, population‐based study we investigated the prevalence of lifestyle changes, factors associated with lifestyle changes and associations between lifestyle changes and general quality of life.

Methods

All men registered in the National Prostate Cancer Register of Sweden diagnosed in 2008 with low‐risk prostate cancer at age 70 years or younger were sent a questionnaire. Logistic regression was used to calculate odds ratios (ORs) with 95% confidence intervals for factors potentially associated with lifestyle change.

Results

Out of 1288, 1720 men (75%) were responded. A total of 279 (22%) reported a positive lifestyle change regarding diet or exercise. Poor functional outcomes after treatment was associated with exercising less (OR 1.6, 95% CI 1.2‐2.1) and less interest in social activities and relationships (OR 1.8, 95% CI 1.5‐2.1). Men who exercised more (OR 7.9, 95% CI 4.4‐14) and men who had an increased interest in relationships and social activities (OR 5.2, 95% CI 2.1‐13) reported higher general quality of life.

Conclusions

A considerable proportion of men reported making positive lifestyle changes after the prostate cancer diagnosis. The time after diagnosis may be a teachable moment that facilitates lifestyle interventions. Poor functional outcomes after treatment may reduce the willingness to engage in positive lifestyle change, which need be considered when supporting men after treatment. Men who made a positive lifestyle change, regardless of whether it was exercise or regarding relationships and social activities more often reported a high level of general quality of life.
