Couples coping with nutrition-related problems in advanced cancer: A qualitative study in primary care

Associations of dyadic appraisal of cancer cachexia symptoms with psychological distress and quality of life in dyads of palliative care patients: a longitudinal mixed-methods study protocol

BACKGROUND

Cancer cachexia (CC) is a fatal syndrome most prevalent in palliative care patients and is typically characterized by a progressive increase in weight loss and anorexia. The inability to detect and accurately appraise CC symptoms early can lead to a delayed diagnosis of CC and late initiation of symptom management, subsequently resulting in shorter survival. Research has shown that both patients and primary family caregivers are burdened by worsening CC symptoms, making them susceptible to reduced quality of life (QOL) and increased psychological distress in particular, and necessitating an exploration of ways to improve their well-being. Guided by the Theory of Dyadic Illness Management supplemented by the Symptom Appraisal Pathway Model, the study will be the first to provide a comprehensive understanding of the role of dyadic appraisal of patients' CC symptoms on psychological distress and QOL of palliative care patients and their primary family caregivers over an eight-week follow-up period.

METHODS

This study will adopt a longitudinal mixed-methods design, combining both quantitative and qualitative data collection at baseline and eight weeks after baseline. 281 dyads of patients with CC and caregivers will be recruited from palliative care units of three hospitals in Hong Kong. Both patients and caregivers will complete a set of questionnaires measuring appraisal of patients' CC symptoms and own psychological distress, and QOL, separately. Semi-structured joint interviews will also be conducted with the same dyads. Quantitative data will be analyzed using the actor-partner interdependence model and the polynomial regression with response surface analysis, while qualitative data will be subjected to qualitative content analysis and trajectory analysis. The findings of the two datasets will be integrated via joint displays.

DISCUSSION

Findings of this study are expected to advance the emerging science on dyadic symptom management by testing the utility of the theory of Dyadic Illness Management and the Symptom Appraisal Pathway Model, but also to inform the design and content of a theory- and evidence-based CC management intervention to reduce psychological distress and to achieve optimal QOL in CC dyads.

Striving towards normality in an unpredictable situation. A qualitative interview study of how persons newly diagnosed with incurable oesophageal and gastric cancer manage everyday life

PURPOSE

Getting an incurable oesophageal or gastric cancer diagnosis is a major stressful life event associated with severe physical, psychosocial and existential challenges. To provide timely and efficient support, based on patients' experiences, the aim of the study was to explore how patients newly diagnosed with incurable oesophageal and gastric cancer manage everyday life.

METHOD

Semi-structured interviews were conducted with 12 patients 1-3 months after being diagnosed with incurable oesophageal or gastric cancer. Four participants were interviewed twice, which resulted in 16 interviews. Data were analysed with qualitative content analysis.

RESULTS

An overall theme, "Striving towards normality in an unpredictable situation", with three related themes - "Trying to comprehend the disease", "Dealing with the consequences of illness" and "Re-evaluating what is important in everyday life" - and seven sub-themes were identified. The participants described an unexpected and unpredictable situation, in which they strived to maintain their normal life. Amidst struggling to manage problems related to eating, fatigue and an incurable diagnosis the participants talked about the importance of focusing on the positive and normal aspects of life.

CONCLUSIONS

The findings in this study point to the importance of supporting patients' confidence and skills, particularly with regard to managing eating, so that they can hold on to their normal life as much as possible. The findings further point to the possible benefit of integrating an early palliative care approach and could provide guidance for nurses and other professionals on how to support patients post diagnosis.

Shared and Divergent Epigenetic Mechanisms in Cachexia and Sarcopenia

Significant loss of muscle mass may occur in cachexia and sarcopenia, which are major causes of mortality and disability. Cachexia represents a complex multi-organ syndrome associated with cancer and chronic diseases. It is often characterized by body weight loss, inflammation, and muscle and adipose wasting. Progressive muscle loss is also a hallmark of healthy aging, which is emerging worldwide as a main demographic trend. A great challenge for the health care systems is the age-related decline in functionality which threatens the independence and quality of life of elderly people. This biological decline can also be associated with functional muscle loss, known as sarcopenia. Previous studies have shown that microRNAs (miRNAs) play pivotal roles in the development and progression of muscle wasting in both cachexia and sarcopenia. These small non-coding RNAs, often carried in extracellular vesicles, inhibit translation by targeting messenger RNAs, therefore representing potent epigenetic modulators. The molecular mechanisms behind cachexia and sarcopenia, including the expression of specific miRNAs, share common and distinctive trends. The aim of the present review is to compile recent evidence about shared and divergent epigenetic mechanisms, particularly focusing on miRNAs, between cachexia and sarcopenia to understand a facet in the underlying muscle wasting associated with these morbidities and disclose potential therapeutic interventions.

Dyadic Experiences and Psychosocial Management of Couples Facing Advanced Cancer: A Systematic Review of the Literature

Background

Cancer diagnosis and treatment represent a real upheaval both for the patient and for his or her life partner. Adjustment to cancer has been widely studied at the individual level, however, there is little in the literature about the experiences of the couple as an entity. This is especially true with regard to a population facing advanced cancer. This systematic review aimed to make an inventory of 1) the current knowledge relating to the experience of the patient-partner dyad when confronted with advanced cancer, and 2) the psychosocial interventions specifically centered on this dyad.

Method

This review was conducted using the Cochrane methodology. The eligibility criteria for the literature review were: one of the members of the dyad being treated for advanced cancer, dyad composed of the patient and his/her life partner. Databases from PubMed, PsycArticle, PsycInfo, Psychology and Behavioral Sciences Collection and Scopus were investigated. A thematic content analysis on the basis of admitted articles made it possible to respond to each of our research objectives.

Results

Three hundred eighty-nine citations were found. Twenty were admitted to the systematic review of the literature. It highlighted the following experiences of the advanced cancer patient-life partner dyad: uncertainty about the future, disjointed time, intrusion into the couple's intimacy, attachment style and caregiving within the couple, couple's adjustment to cancer symptomatology, the couple's supportive care needs, role changes, nature of communication within the couple, anticipation of the coming death, and the meanings and beliefs around death. This review also describes the range of couple therapies used in the context of advanced cancer: emotionally focused-couple therapy, existential therapy, art therapy, support therapy and couple communication and intimacy promotion. These therapies seem to have individual beneficial effects for both the patient and his or her life partner as well as improving marital functioning.

Conclusions

These results clearly highlight that consideration of the couple and communication within the couple during care are fundamental to dyadic adjustment to advanced cancer. Further studies (qualitative and quantitative) are needed to better understand the couple's experience in order to adapt the management of the couple facing advanced cancer.

The experiences, perceptions, and support needs among family caregivers of patients with advanced cancer and eating problems: An integrative review

BACKGROUND

Advanced cancer patients often present with numerous eating problems, posing a significant challenge for family caregivers during the provision of nutritional care.

AIM

To systematically identify and synthesize empirical literature on the experiences, perceptions, and support needs of family caregivers of patients with advanced cancer and eating problems to ascertain directions for future research.

DESIGN

Integrative review guided by Whittemore and Knafl's methodological framework.

DATA SOURCES

Five electronic databases were searched from their inception to April 2021. Studies were eligible if they examined family caregivers' perspectives and experiences when caring for their relatives with advanced cancer and eating problems and were primary quantitative, qualitative, and mixed-methods studies published in English-language peer-reviewed journals. The Mixed Methods Appraisal Tool was used to evaluate the quality of the studies.

RESULTS

Twenty-seven papers from 21 studies met the eligibility criteria and were included in this review. The included papers were mostly qualitative studies and were of moderate to high methodological quality. Three themes were identified: (a) multiple negative effects of advanced cancer patients' eating problems; (b) coping responses in managing advanced cancer patients' eating problems; and (c) unmet support needs in the provision of nutritional care.

CONCLUSIONS

Research on the studied topic was descriptive and predominantly qualitative in nature. Quantitative research examining the impact of caregiving experiences in relation to food and eating in the context of advanced cancer patients is the first important step moving this research area forward.

Decision Making of Artificial Nutrition and Hydration for Cancer Patients at Terminal Stage-A Systematic Review of the Views From Patients, Families, and Healthcare Professionals

BACKGROUND

Decision making on nutrition and hydration for cancer patients during terminal stage cause critical impacts toward patient's comfort and living quality. The management of nutrition is the main dilemma that arises in these final situations and has been the subject of intense debate over the last few decades.

AIM

To find the views of patients, families, and healthcare professionals related to how decisions are made when cancer patients are at terminal stage.

DESIGN

This systematic review used PRISMA strategy to search and used Critical Appraisal Skills Programme checklist to evaluate the papers.

DATA SOURCES

All English papers through August 2020 that contained the view of the decision making at artificial nutrition and hydration with cancer patients, families, and healthcare professionals at terminal stage were included. Selected studies were independently reviewed, and data collaboratively synthesized into core themes.

RESULTS

Most of the terminal stage cancer patients and their families initially started the decision-making process when facing the reduction of oral intake. There are two primary considerations of patients and families, one is for prolonging patients life, and the other is to maintain their life quality. The voices of patients were influential, but not determinative; families usually had influence, but seldom make the final recommendation by themselves; healthcare professionals frequently face the dilemma about their decision.

CONCLUSION

The decision of nutritional support was dynamic; the interaction between patients and families frequently be hesitated to protect the rights of life, unnecessarily prolonging lifetime. Therefore, a better understanding of the views on nutritional support and processing the clinical guideline of decision making for healthcare professional is necessary.

The experiences and needs of couples affected by prostate cancer aged 65 and under: a qualitative study

PURPOSE

Prostate Cancer (PCa) is often considered to be an illness affecting older men, however the prevalence in younger men (<=65 years) is rising. Diagnosis and treatment for PCa can have a significant impact on the lives of both the man with PCa and his partner. This study explored the experiences and needs of younger men and their partners affected by PCa. The findings will be used to inform service provision and develop interventions appropriate to need.

METHODS

Participants were recruited from respondents to a national PROMS study (Life After Prostate Cancer Diagnosis (LAPCD), who indicated on completed questionnaires their willingness to be interviewed. Semi-structured telephone interviews were conducted with twenty-eight couples, separately (56 participants). Data were analysed using the Framework Method.

RESULTS

Following the diagnosis of PCa, couples' experienced changes in their intimate relationships, parental/familial roles, work and finances, and social connections and activities. Couples adopted a range of strategies and behaviours to help their adjustment to PCa, such as communicating with each other, distancing, distraction, and adopting a positive mindset towards PCa. This, in turn, influenced how their identity as a couple evolved.

CONCLUSIONS

Following a diagnosis of PCa, the identity of couples are continually evolving. It is important that these couples are provided with the appropriate information, support and resources to help them transition along the cancer pathway.

IMPLICATIONS FOR CANCER SURVIVORS

Key areas of support identified for younger couples include: 1) couple focused support programme to foster relationship strategies/behaviours that facilitate couple adjustment; 2) age-specific support, e.g. 'buddying systems' connecting younger couples affected by PCa and providing them with tailored information (written/online/app).

Flavor alterations in cancer treatment: Extrinsic factors as a means of augmentation

Flavor, comprising taste, smell and somatosensory inputs, is commonly altered in patients undergoing chemotherapy resulting in malnutrition leading to cachexia. A narrative review considered taste and smell alterations associated with malignancies treated using chemotherapy and the various interventions proffered to lessen alterations. Many of the currently used interventions directed towards enhancing intrinsic factors of food appeared ineffective in encouraging intake of adequate nutrition to ward off complications of malnutrition. Counselling is used in some cases with positive results. The use of extrinsic influences commensurate with the principles of food behavior and gastronomy are considered as a means of providing purpose to patients to accommodate flavor loss which when integrated with counseling and appropriate intrinsic factors are potentially a means of curtailing malnutrition and enhancing the psychological status of the patient. The close association between the cephalic phase responses (CPRs) and the control of eating and digestive behaviors is multifaceted, and when the influences of taste and smell are diminished, other contributing factors guiding CPRs may compensate a deficit. The need for the application of a consistent lexicon is essential when describing taste and smell alterations.

The effects of a family-centered psychosocial-based nutrition intervention in patients with advanced cancer: the PiCNIC2 pilot randomised controlled trial

Background

Malnutrition in advanced cancer patients is common but limited and inconclusive data exists on the effectiveness of nutrition interventions. Feasibility and acceptability of a novel family-based nutritional psychosocial intervention were established recently. The aims of this present study were to assess the feasibility of undertaking a randomised controlled trial of the latter intervention, to pilot test outcome measures and to explore preliminary outcomes.

Methods

Pilot randomised controlled trial recruiting advanced cancer patients and family caregivers in Australia and Hong Kong. Participants were randomised and assigned to one of two groups, either a family-centered nutritional intervention or the control group receiving usual care only. The intervention provided 2–3 h of direct dietitian contact time with patients and family members over a 4–6-week period. During the intervention, issues with nutrition impact symptoms and food or eating-related psychosocial concerns were addressed through nutrition counselling, with a focus on improving nutrition-related communication between the dyads and setting nutritional goals. Feasibility assessment included recruitment, consent rate, retention rate, and acceptability of assessment tools. Validated nutritional and quality of life self-reported measures were used to collect patient and caregiver outcome data, including the 3-day food diary, the Patient-Generated Subjective Global Assessment Short Form, the Functional Assessment Anorexia/Cachexia scale, Eating-related Distress or Enjoyment, and measures of self-efficacy, carers’ distress, anxiety and depression.

Results

Seventy-four patients and 54 family caregivers participated in the study. Recruitment was challenging, and for every patient agreeing to participate, 14–31 patients had to be screened. The consent rate was 44% in patients and 55% in caregivers. Only half the participants completed the trial’s final assessment. The data showed promise for some patient outcomes in the intervention group, particularly with improvements in eating-related distress (p = 0.046 in the Australian data; p = 0.07 in the Hong Kong data), eating-related enjoyment (p = 0.024, Hong Kong data) and quality of life (p = 0.045, Australian data). Energy and protein intake also increased in a clinically meaningful way. Caregiver data on eating-related distress, anxiety, depression and caregiving burden, however, showed little or no change.

Conclusions

Despite challenges with participant recruitment, the intervention demonstrates good potential to have positive effects on patients’ nutritional status and eating-related distress. The results of this trial warrant a larger and fully-powered trial to ascertain the effectiveness of this intervention.

Trial registration

The trial was registered with the Australian & New Zealand Clinical Trials Registry, registration number ACTRN12618001352291.

Resilience in family caregivers of patients diagnosed with advanced cancer - unravelling the process of bouncing back from difficult experiences, a hermeneutic review

Background

Despite the risk for developing mental disorders, most of advanced cancer patients’ family caregivers undergo a resilient process throughout the caregiving period. Research on resilience in caregivers of advanced cancer patients is scarce and further hindered by the lack of a univocal definition and a theoretical framework.

Objectives

To provide clarity on the concept of resilience by proposing an integrative view that can support health care professionals and researchers in conducting and interpreting research on resilience.

Methods

The review process was inspired by the hermeneutic methodology: a cyclic review process, consisting of repeated searching and analysing until data saturation is reached and focussed on achieving a deeper understanding of ill-defined concepts. The definitions from eighteen reviews on resilience and the theoretical frameworks from eight concept analyses were analysed. The composing elements of resilience were listed and compared.

Results

The American Psychological Association’s definition of resilience and Bonanno’s theoretical framework are suggested to guide further research on resilience. Moreover, four knowledge gaps were uncovered: (1) How do resilience resources interact? (2) What are the key predictors for a resilient trajectory? (3) How do the resilient trajectories evolve across the caregiving period? And (4) how does the patient’s nearing death influence the caregiver’s resilience?

Conclusion

To address flaws in conceptualisation and the resulting gaps in knowledge, we suggest a definition and a theoretical framework that are suited to allow heterogeneity in the field, but enables the development of sound interventions, as well as facilitate the interpretation of intervention effectiveness.
