Demoralization in cancer survivors: an updated systematic review and meta-analysis for quantitative studies.

BACKGROUND: Demoralization can cause impairments across all life aspects of cancer patients. Cancer patients are also vulnerable during their survivorship. The purpose of this review is to examine the risk of demoralization and associated risk factors among cancer survivors who have completed their primary anti-cancer treatment or time since diagnosis ≥5 years without recurrence. METHODS: We searched databases of PubMed, Cochrane, Embase, PsycINFO and ClinicalTrial.gov to identify eligible studies which reported the demoralization level among cancer survivors. A random-effect meta-analysis model was used for calculating mean demoralization level. Heterogeneity was evaluated by I2 statistics. Funnel plots and Egger's regression tests were performed for checking publication bias. We used one-study-removed method for sensitivity analysis. Subgroup analysis was also done to examine the difference of demoralization level between cancer types. Meta-regression was performed to reveal risk factors of demoralization. RESULTS: A meta-analysis of 12 articles involving 2902 cancer survivors was conducted. The mean demoralization score among cancer survivors was 25.98 (95% CI: 23.53-28.43). Higher demoralization level was seen in participants with older age, higher female ratio, higher married/living together status ratio and higher patient health questionnaire-9 score. The literature review revealed correlations between demoralization and suicide risk, anxiety and quality of life. No consistent correlation between demoralization and post-traumatic stress symptoms could be seen. CONCLUSIONS: High demoralization level is noticed among cancer survivors. Risks for females, elder patients or breast cancer survivors are identified. More longitudinal or interventional studies for cancer survivors' demoralization are expected in the future.

Acute Mountain Sickness and the Risk of Subsequent Psychiatric Disorders-A Nationwide Cohort Study in Taiwan.

We aim to explore if there is a relationship between acute mountain sickness (AMS) and the risk of psychiatric disorders in Taiwan by using the National Health Insurance Research Database for to the rare studies on this topic. We enrolled 127 patients with AMS, and 1270 controls matched for sex, age, monthly insured premiums, comorbidities, seasons for medical help, residences, urbanization level, levels of care, and index dates were chosen from 1 January 2000 to 31 December 2015. There were 49 patients with AMS and 140 controls developed psychiatric disorders within the 16-year follow-up. The Fine-Gray model analyzed that the patients with AMS were prone to have a greater risk for the development of psychiatric disorders with an adjusted sub-distribution hazard ratio (sHRs) of 10.384 (95% confidence interval [CI]: 7.267-14.838, p < 0.001) for psychiatric disorders. The AMS group was associated with anxiety disorders, depressive disorders, bipolar disorder, sleep disorders, posttraumatic stress disorder/acute stress disorder, psychotic disorder, and substance-related disorder (SRD). The relationship between anxiety, depression, sleep disorders, SRD, and AMS still persisted even after we excluded the psychiatric disorders within the first five years after AMS. There was an association between AMS and the rising risk of psychiatric disorders in the 16 years of long-term follow-up research.
