RESUMO
PURPOSE: The purpose of this study was to investigate the impact of social isolation and loneliness on the overall survival and death at home in patients with lung cancer. METHODS: This prospective cohort study was conducted in a Japanese tertiary hospital. The enrollment period was from April 2018 to March 2020. Patients with pathologically diagnosed advanced lung cancer were included in this study. The primary outcome was overall survival, whereas the secondary outcome was death at home. The exposures were social isolation and loneliness. RESULTS: A total of 211 patients were enrolled and divided into two groups and further into quartiles according to their social isolation and loneliness level, respectively. The hazard ratios of social isolation were 1.65 (95% confidence interval; 1.12 to 2.44) and 1.87 (95% confidence interval; 1.15 to 3.03) in the univariate analysis, while 1.40 (95% confidence interval; 0.92 to 2.13) in the multivariate analysis with complete case and multiple imputation. The odds ratio of death at home with social isolation was 3.47 (95% confidence interval; 1.08 to 11.1) in the multivariate analysis with multiple imputation. Loneliness was not associated with overall survival or death at home. CONCLUSIONS: Our study suggests that social isolation may be related to overall survival and death at home among patients with advanced lung cancer. More attention should be given to such patients at the time of diagnosis.

BACKGROUND: Social determinants of health (SDHs) are social factors that affect human health; loneliness and social isolation are core SDH factors. There is a possibility that SDHs are related to passive decision-making. However, few studies have evaluated SDHs, especially social isolation and loneliness, among lung cancer patients. This study aims to investigate the effects of social isolation and loneliness on the diagnosis and treatment of Japanese lung cancer patients. METHODS: This is a prospective cohort study that was conducted in a tertiary referral hospital in Japan (University Hospital Medical Information Network registration: UMIN000031810). The enrollment period was between April 2018 and March 2020. Patients with clinical and/or pathological diagnosis of lung cancer were enrolled in this study. Exposures were social isolation and loneliness, and main outcomes were diagnosis methods and whether the initial treatment involved active therapy or best supportive care (BSC). The confounding factors were defined as sex, age, smoking status, respiratory symptoms, weight loss, presentation with any symptoms, Eastern Cooperative Oncology Group (ECOG) performance status, tumor nodes metastasis (TNM) classification, driver gene mutations [i.e., epidermal growth factor receptor (EGFR), anaplastic lymphoma kinase (ALK)], and programmed death-ligand 1 (PD-L1) tumor proportion score. RESULTS: The study enrolled 264 patients who were divided into quartiles according to their loneliness scores and into two groups according to the social isolation level. Univariate analysis, complete case analysis, and multivariate analysis with multiple imputation failed to detect significant differences in diagnostic method or initial treatment strategy according to loneliness or social isolation level. CONCLUSIONS: Physicians may not need to consider a patient's loneliness and/or social isolation when diagnosing lung cancer and selecting treatment under universal health insurance coverage. Further studies are needed to understand the influences of loneliness and social isolation on the prognosis of lung cancer patients.

BACKGROUND/AIM: Previous reviews of Social determinants of health in lung cancer patients have not examined essential factors such as social isolation and loneliness. This study aimed to explore the factors affecting social isolation and loneliness among lung cancer patients. PATIENTS AND METHODS: A cross-sectional study was conducted. Social isolation, loneliness, and the presence of dementia were measured using Japanese adaptations of the Lubben Social Network Scale, UCLA Loneliness Scale, and Life Function Evaluation for Care Provision, respectively. RESULTS: From March 2019 to March 2020, 264 patients were included. Social isolation was significantly higher for patients receiving welfare (adjusted OR=5.28, 95% CI=2.24-12.4). Loneliness was significantly higher for patients receiving welfare (beta coefficient=0.52, 95% Cl=0.13-0.90) with symptoms of dementia (beta coefficient=0.28, 95% Cl=0.03-0.54). CONCLUSION: Results showed that receiving welfare was associated with experiencing social isolation. Receiving welfare and symptoms of dementia were associated with experiencing loneliness.

AIM: The aim of the present study was to assess the prognostic utility of the pretreatment blood neutrophil-to-lymphocyte ratio (NLR) and the C-reactive protein-to-albumin ratio (CAR) in patients with inoperable malignant pleural mesothelioma (MPM). MATERIALS AND METHODS: The medical records of consecutive patients with histologically confirmed MPM from our hospital between January 2007 and August 2017 were retrospectively reviewed. The primary outcome was overall survival (OS). Univariate and multivariate analyses for the prognostic factors were performed using a Cox proportional hazards model. RESULTS: A total of 143 patients with inoperable MPM were included. On multivariate analysis, pretreatment CAR was an independent factor associated with worse OS (hazard ratio(HR)=1.72; 95% confidence interval(CI)=1.11-2.67; p=0.016). However, NLR was not associated with OS in any of the analyses. CONCLUSION: CAR appears to be a prognostic factor in patients with inoperable MPM.

Phlebosclerotic colitis presents with ischemic bowels and calcification of the mesenteric veins. Owing to its rarity, we have little information on the complications of this disease. Herein, we report on a 77-year-old woman with phlebosclerotic colitis and interstitial lung disease. She was diagnosed as having phlebosclerotic colitis by CT and colonoscopy. At the same time, chest CT also showed interstitial lung disease. After 4 years, she experienced exacerbation of interstitial lung disease. She recovered without treatment. The occurrence of interstitial lung disease may have been associated with her phlebosclerotic colitis.
RESUMO
INTRODUCTION: Socioeconomic factors with an influence on human health are known as social determinants of health (SDH). There are some SDH studies in patients with lung cancer, but important exposures such as social isolation and loneliness have not been adequately investigated. This study will assess the influence of SDH, particularly social isolation and loneliness, on patients with advanced lung cancer in Japan. METHODS AND ANALYSIS: The inclusion criteria for this prospective cohort study will be as follows: a diagnosis of advanced lung cancer; unsuitability for curative surgery; and willingness to participate. The primary outcome will be the initial choice of treatment and the secondary outcomes will be overall survival, changes in disease staging or performance status, route to diagnosis and place of death. The exposures will be social isolation, loneliness, employment, insurance type, education and dementia. The study enrolment period will be 1 year and the follow-up duration will be 2 years. The log-rank test will be used to compare overall survival between patients when grouped according to the study exposures and multivariate analysis will be performed using Cox proportional hazards regression. The Χ2 test will be used to compare the initial treatment, changes in disease stage and place of death, and logistic regression will be used for multivariate analysis of these factors. A p value <0.05 will be considered statistically significant. ETHICS AND DISSEMINATION: This study has been approved by the Institutional Review Board at Hyogo Prefectural Amagasaki General Medical Center (No 29-164). A manuscript summarising the outcome of this study will be submitted to a peer-reviewed journal and the data will be presented at conferences. TRIAL REGISTRATION NUMBER: UMIN000031810.
