Higher Dispositional Optimism Predicts Better Health-Related Quality of Life After Esophageal Cancer Surgery: A Nationwide Population-Based Longitudinal Study

Temporal stability of optimism and pessimism (LOT-R) over 6 years in the general population

Objective

The aims of this study were to examine changes in habitual optimism over a six-year period and to analyze the relationship between changes in optimism and changes in other quality of life-related variables.

Method

A randomly selected community sample of the German adult general population (N = 4,965) was surveyed twice, with a time interval of 6.04 years.

Results

During the course of the 6 years, the mean score of the LOT-R total scale improved (effect size d = 0.11). The temporal stability in terms of the test-retest correlation was r = 0.61 for the total sample. There were only marginal gender differences in this temporal stability, however, the stability in the oldest age group ≥70 years (r = 0.50) was lower than the stability of the other age groups. The cross-sectional correlations showed clear relationships between optimism on the one hand and quality of life, life satisfaction, social support, and low levels of anxiety and physical complaints on the other. The corresponding longitudinal correlations between changes in optimism and changes in the other variables were less pronounced, but in the same direction.

Conclusion

The study confirmed the applicability of the LOT-R in longitudinal studies. In samples with participants of 70 years and above, the limited stability in the optimism assessments needs to be considered in clinical practice and epidemiologic research.

Research progress on the psychological burden and intervention measures in cancer patients

In the past 40 years, the gradually increasing incidence and mortality rates of malignant tumors have severely impacted the quality of life of patients, bringing significant physical and psychological burdens and becoming an increasingly serious social issue. With the development of medical standards, new methods for cancer detection and treatment have been continuously proposed. Although it has been proven that cancer is related to increased psychological burden and suicidal behaviors in patients, current research on the psychological burden caused by cancer is insufficient. Clinicians often overlook the psychological health issues of patients while treating their physical diseases. Considering the high incidence of cancer, this review will outline the psychological burdens of cancer patients worldwide in recent years and its high-risk factors. Moreover, this review will summarize the common methods for evaluating psychological burdens, present current predictive models and treatment methods for the psychological burden of cancer patients, aiming to provide a research basis and future direction for the timely and accurate assessment of the psychological burden in cancer patients.

Association of optimism and social support with health-related quality of life among Australian women cancer survivors - A cohort study

AIM

Large-scale studies investigating health-related quality of life (HRQL) in cancer survivors are limited. This study aims to investigate HRQL and its relation to optimism and social support among Australian women following a cancer diagnosis.

METHODS

Data were from the Australian Longitudinal Study on Women's Health, a large cohort study (n = 14,715; born 1946-51), with 1428 incident cancer cases ascertained 1996-2017 via linkage to the Australian Cancer Database. HRQL was measured using the Short Form-36 (median 1.7 years post-cancer-diagnosis). Multivariable linear regression was performed on each HRQL domain, separately for all cancers combined, major cancer sites, and cancer-free peers.

RESULTS

Higher optimism and social support were significantly associated with better HRQL across various domains in women with and without a cancer diagnosis (p < 0.05). Mean HRQL scores across all domains for all cancer sites were significantly higher among optimistic versus not optimistic women with cancer (p < 0.05). Adjusting for sociodemographic and other health conditions, lower optimism was associated with reduced scores across all domains, with greater reductions in mental health (adjusted mean difference (AMD) = -11.54, p < 0.01) followed by general health (AMD = -11.08, p < 0.01). Social support was less consistently related to HRQL scores, and following adjustment was only significantly associated with social functioning (AMD = -7.22, p < 0.01) and mental health (AMD = -6.34, p < 0.01).

CONCLUSIONS

Our findings highlight a strong connection between optimism, social support, and HRQL among cancer survivors. Providing psychosocial support and addressing behavioral and socioeconomic factors and other health conditions associated with optimism and social support may improve HRQL.

Quality of life and its association with predictors in lung transplant recipients: a latent profile analysis

Backgrounds

Improving quality of life (QOL) is one of the main aims of lung transplantation (LTx). There is a need to identify those who have poor quality of life early. However, research addressing inter individual quality of life variability among them is lacking. This study aims to identify group patterns in quality of life among lung transplant recipients and examine the predictors associated with quality of life subgroups.

Methods

In total, 173 lung transplant recipients were recruited from one hospital in Guangdong Province between September 2022 and August 2023. They were assessed using the Lung Transplant Quality of Life scale (LT-QOL), Mindful Attention Awareness Scale (MAAS), Life Orientation Test-Revised scale (LOT-R), and Positive and Negative Affect Scale (PANAS). Latent profile analysis was used to identify QOL subtypes, and logistic regression analysis was used to examine the associations between latent profiles and sociodemographic and psychosocial characteristics.

Results

Two distinct QOL profiles were identified: "low HRQOL" profile [N = 53 (30.94%)] and "high HRQOL" profile [N = 120 (69.06%)]. Single lung transplant recipients, and patients who reported post-transplant infection, high levels of negative emotion or low levels of mindfulness and optimism were significantly correlated with the low QOL subgroup.

Conclusion

Using the domains of the LT-QOL scale, two profiles were identified among the lung transplant recipients. Our findings highlighted that targeted intervention should be developed based on the characteristics of each latent class, and timely attention must be paid to patients who have undergone single lung transplantation, have had a hospital readmission due to infection, exhibit low levels of optimism, low levels of mindfulness or high negative emotions.

Gender differences in the predictors of quality of life in patients with cancer: A cross sectional study

PURPOSE

The aim of the present study was to explore potential differences in the sociodemographic (with a special focus on gender differences) and psychological predictors of quality of life in individuals diagnosed with cancer.

METHODS

A cross-sectional, observational study was carried out involving individuals struggling with different forms of cancer (N = 430). Linear regression was used to investigate the concurrent predictive role of the independent variables, stratified by gender, for each of the five cancer-specific quality of life domains and overall quality of life.

RESULTS

Sociodemographic characteristics had only a negligible to small role in predicting quality of life in both men and women. In contrast, the psychological variables explained a significantly larger portion of the variance in both genders. There were no statistically significant gender differences regarding the raw quality of life domain scores; however, their predictors were markedly different in the two groups.

CONCLUSION

The results of the present study indicate that it is imperative to take gender differences into consideration when planning psychosocial interventions also focusing on strengths, resources, and coping strategies. Considering the consistently emerging importance of family support in patients' quality of life, offering psychological interventions to caregivers/family members seems warranted to empower them to provide support to patients throughout the illness trajectory.

Translating evidence in a priority setting partnership: knowledge gaps between healthcare providers and oesophageal cancer patients

INTRODUCTION

Despite the fact that health information is now more accessible than ever, knowledge gaps remain between patients and healthcare providers (HCPs). To date, the patients' need for information following a diagnosis of oesophageal cancer has not been adequately met.

PURPOSE

The purpose of this study was to identify why knowledge gaps exist between oesophageal cancer patients and HCPs and how to address them.

METHODS

Purposive sampling of a group of people living with and after oesophageal cancer who had participated in a priority-setting partnership where 45% of questions from patients had existing evidence-based answers. A 7-set question series was developed for use in a patient/HCP focus group in addition to 11 individual phone interviews with survivors of oesophageal cancer. Qualitative semistructured interviews were conducted to explore oesophageal cancer patients' access to information. The data was analysed thematically, which involved coding all patient transcripts before identifying and reviewing key themes.

RESULTS

The three primary themes that emerged were as follows: opportunity (HCP team factors and relationship development), ability (patient factors) and priority (pacing of information delivery).

CONCLUSION

Effective communication between patients and HCPs was identified as an integral component of the enhancement of patient knowledge. HCPs should continue to refine and improve methods of information delivery and encourage conversations regarding information preferences.

The role of optimism in manifesting recovery outcomes after coronary artery bypass graft surgery: A systematic review

OBJECTIVE

Coronary artery bypass graft (CABG) is a major surgery conducted in coronary heart disease management. Postoperative recovery is a crucial process for patients undergoing CABG. This systematic review evaluates current evidence regarding the association between trait optimism and recovery outcomes in patients following coronary artery bypass graft surgery.

METHODS

This review followed the Preferred Reporting Items of Systematic Review and Meta-Analysis (PRISMA) 2020 Guideline. The inclusion criteria focused on observational study that examined study participants aged ≥18 years old undergoing elective CABG and measurement of trait optimism with validated methods (i.e. LOT, LOT-R) and at least one recovery outcome. Studies in non-English languages and duplicates were excluded. A systematic literature search was carried out on PubMed, Scopus, and Web of Science electronic databases. Search results were screened based on the eligibility criteria. The Newcastle-Ottawa Scale was used to assess the quality of each included study.

RESULTS

The search yielded a total of 1853 articles, in which 7 articles fulfilled the eligibility criteria and were subsequently included in the analysis. Measurement of trait optimism was conducted on 1276 patients who underwent a non-emergency/elective CABG. Optimism was significantly associated with several categories of recovery, including reduced rehospitalization rate, complications, pain, and physical symptoms along with improved quality of life, rate of return to normal life, and psychological status.

CONCLUSION

Our review showed that trait optimism was associated with recovery outcomes following CABG surgery. However, the heterogeneity of recovery outcomes may hamper the clinical benefit of trait optimism in CABG. (PROSPERO CRD42022301882).

Patient and public involvement in oesophageal cancer survivorship research

BACKGROUND

Good clinical research is often conducted in close collaboration between patients, the public, and researchers. Few studies have reported the development of patient and public involvement (PPI) in research outside the United States and the United Kingdom, and for patients with more aggressive cancers. The study aimed to describe and evaluate the development of PPI in oesophageal cancer survivorship research in Sweden by the use of a framework to support the process.

METHODS

Oesophageal cancer survivors were recruited to a PPI research collaboration at Karolinska Institutet, Sweden. The development process was supported by the use of a framework for PPI, 'Patient and service user engagement in research'. Insights, benefits, and challenges of the process were described and discussed among the collaborators.

RESULTS

The collaboration resulted in joint publications with a more patient- and family-focussed perspective. It also contributed to the development of information folders about survivorship after oesophageal cancer surgery and national conference arrangements for patients, their families, healthcare workers, and researchers. Since the PPI contributors were represented in patient organisations and care programmes, the dissemination of research results increased. Their contributions were highly valued by the researchers, but also revealed some challenges. The use of a structured framework contributed to support and facilitated the process of establishing PPI in research collaboration.

CONCLUSIONS

A genuine interest in establishing PPI in research and an understanding and respect for the patients' expertise in providing a unique inside perspective was imperative for a successful collaboration. Research focus should not only be on mortality and reductions in daily life, but also on positive outcomes. Using a framework supports development and avoids pitfalls of PPI collaboration.

PATIENT AND PUBLIC CONTRIBUTION

Patient partners were equal collaborators in all aspects of the study.

Dispositional optimism and all-cause mortality after esophageal cancer surgery: a nationwide population-based cohort study

PURPOSE

To examine the association between dispositional optimism and all-cause mortality after esophageal cancer surgery and whether pathological tumor stage and the COVID-19 pandemic modified this association.

METHODS

This nationwide, population-based prospective cohort study included 335 patients undergoing esophageal cancer surgery in Sweden between January 1, 2013, and December 31, 2019. Dispositional optimism was measured 1 year post-surgery using Life Orientation Test-Revised (LOT-R). A higher LOT-R sum score represents higher dispositional optimism. Mortality information was obtained from the Swedish Register of the Total Population. All patients were followed up until death or until December 31, 2020, whichever occurred first. Cox regression with adjustments for confounders was used.

RESULTS

The median follow-up was 20.8 months, during which 125 (37.3%) patients died. Among the included 335 patients, 219 (65.4%) patients had tumor pathologically staged Tis-II, and 300 (89.6%) patients entered the cohort before the COVID-19 pandemic. Both tumor stage and the COVID-19 pandemic were effect modifiers. For each unit increase in LOT-R sum score, the risk of all-cause mortality decreased by 11% (HR 0.89, 95% CI 0.81 to 0.98) among patients with tumor staged Tis-II before the COVID-19 pandemic. This association was non-significant in patients with tumor staged III-IV (HR 0.99, 95% CI 0.92 to 1.07) and during the COVID-19 pandemic (HR 1.08, 95% CI 0.94 to 1.25).

CONCLUSION

Assessing dispositional optimism may help predict postoperative survival, especially for patients with early and intermediate esophageal cancer. Increasing dispositional optimism might be a potential intervention target to improve survival after esophageal cancer surgery.

Psychological distress after esophageal cancer surgery and the predictive effect of dispositional optimism: a nationwide population-based longitudinal study

Purpose

To examine the trajectory of psychological distress from 1 to 2 years after esophageal cancer surgery, and whether dispositional optimism could predict the risk of postoperative psychological distress.

Methods

This Swedish nationwide longitudinal study included 192 patients who had survived for 1 year after esophageal cancer surgery. We measured dispositional optimism with the Life Orientation Test-Revised (LOT-R) 1 year post-surgery and psychological distress with the Hospital Anxiety and Depression Scale 1, 1.5, and 2 years post-surgery. Latent growth curve models were used to assess the trajectory of postoperative psychological distress and to examine the predictive validity of dispositional optimism.

Results

One year after surgery, 11.5% (22 of 192) patients reported clinically significant psychological distress, and the proportion increased to 18.8% at 1.5 years and to 25.0% at 2 years post-surgery. Higher dispositional optimism predicted a lower probability of self-reported psychological distress at 1, 1.5, and 2 years after esophageal cancer surgery. For each point increase in the LOT-R sum score, the odds of psychological distress decreased by 44% (OR, 0.56; 95% CI, 0.40 to 0.79).

Conclusion

The high prevalence and longitudinal increase of self-reported psychological distress after esophageal cancer surgery indicate the unmet demands for timely psychological screening and interventions. Measuring dispositional optimism may help identify patients at higher risk of developing psychological distress, thereby contributing to the prevention of postoperative psychological distress.
