Diet and nutrition in patients who have received pelvic radiotherapy: A mixed-methods study to explore dietary habits, nutritional awareness, and experiences of nutritional care

Experiences of cancer patients in receiving dietary advice from healthcare professionals and of healthcare professionals in providing this advice-a systematic review

PURPOSE

This systematic review investigated qualitative and quantitative studies exploring patients and healthcare professionals' (HCP) experience of nutrition care throughout the cancer journey.

METHODS

Five databases were systematically searched for studies reporting on patient and healthcare professionals' experience of nutrition advice.

RESULTS

Fifteen studies including 374 patients and 471 healthcare professionals were included. Findings indicate that patients desire more specific nutrition advice supported by members of the multidisciplinary team and delivered in appropriate and understandable language. Healthcare professionals have highlighted a lack of time, funding, dietetic roles, and knowledge as barriers to integrating nutrition as a standard part of cancer care. Five themes were identified (current provision of nutrition advice, optimal provision of nutrition advice, tension between patient values and nutritional or HCP priorities, providing evidence-based nutrition care, and practical barriers to nutrition advice provision).

CONCLUSIONS

Further work is essential to better understand and address identified barriers and improve the provision of nutrition advice to this population.

IMPLICATIONS FOR CANCER SURVIVORS

Findings from this review will guide the delivery of nutrition advice for cancer survivors.

Nutrition and behavior change: a review of recent literature

PURPOSE OF REVIEW

The current article will highlight recent trends and novel approaches to behavior change strategies in nutrition. Physicians, nurses, and other healthcare professionals play key roles in counseling patients on lifestyle change, which is critical for patients with chronic conditions. Nutrition science continues to advance, and new approaches to behavior change are needed for successful implementation at the individual and population level.

RECENT FINDINGS

The solutions to obstacles around healthful eating patterns are varied, population-dependent, and require a multipronged approach. One area of focus is the language around behavior change, ensuring it is clear and emphasizes its multifactorial nature. For young adults, the careful use of video games and social media may be essential. For older adults, altering food consistency and ensuring proper nutrient intake are crucial factors. Vulnerable populations remain susceptible to malnutrition and need special attention. Despite significant advances in managing and treating diseases, there are still gaps in nutrition counseling and behavior change efforts.

SUMMARY

Every age and stage of life needs a focus on healthful foods, and nutrition counseling at each stage has its unique nuances. Careful attention to the language of change and the phrasing used in counseling is vital for educating, connecting with, and empowering patients to change. Changing healthcare operations and provider behavior around nutrition counseling is a part of the solution to the worldwide problem of unhealthy eating patterns and practices.

Life style and interaction with microbiota in prostate cancer patients undergoing radiotherapy: study protocol for a randomized controlled trial

Background

Prostate cancer (PCa) is the second most common cancer in men worldwide. The standard non-surgical approach for localized PCa is radiotherapy (RT), but one of the limitations of high-dose RT is the potential increase in gastrointestinal and genitourinary toxicities. We present the protocol of the Microstyle study, a multicentre randomized two-arm crossover clinical trial. The primary outcome will be assessed at the end of 6-month intervention, by measuring the change in adherence to a healthy lifestyle score. The hypothesis is that modifying lifestyle we change microbiome and improve quality of life and decrease side effects of RT.

Methods

Study participants will be recruited among men undergoing RT in two Italian centers (Milan and Naples). We foresee to randomize 300 patients in two intervention arms: Intervention Group (IG) and Control Group (CG). Participants allocated to the IG will meet a dietitian and a physiotherapist before RT to receive personalized diet and exercise recommendations, according to their health status, to improve overall lifestyle and reduce side effects (bowel and/or urinary problems). Dietitian and physiotherapist will work together to set individualized goals to reduce or eliminate side effects and pain according to their health status. All participants (IG) will be given a pedometer device (steps counter) in order to monitor and to spur participants to increase physical activity and reduce sedentary behavior. Participants included in the CG will receive baseline general advice and materials available for patients undergoing RT. According to the cross-over design, the CG will cross to the intervention approach after 6-month, to actively enhance compliance towards suggested lifestyle recommendations for all patients.

Discussion

This trial is innovative in its design because we propose a lifestyle intervention during RT, that includes both dietary and physical activity counselling, as well as monitoring changes in microbiome and serum biomarkers. The promotion of healthy behaviour will be initiated before initiation of standard care, to achieve long lasting effects, controlling side effects, coping with feelings of anxiety and depression and improve efficacy of RT.
