A new landscape in illness uncertainty: A systematic review and thematic synthesis of the experience of uncertainty in patients with advanced cancer receiving immunotherapy or targeted therapy.

OBJECTIVE: Over the past 20 years, immunotherapy and targeted therapy (TT) have been extending the life expectancy and providing hope for a growing number of patients with advanced and metastatic cancer. However, the efficacy, side effects, and overall prognosis of these treatments are highly unpredictable. Recent research suggests that these patients may be experiencing significant uncertainty which impacts their functioning. This study reviewed the literature on the experiences of uncertainty for individuals with advanced or metastatic cancer patients who are receiving immunotherapy or TT. METHOD: A systematic literature review was conducted. Data was extracted from studies by pairs of reviewers. Literature quality was appraised using the Critical Appraisal Skills Program checklist. Following data extraction, thematic synthesis was used to summarize findings across studies and generate overarching themes. RESULTS: Fifteen qualitative studies were included. Findings highlighted impacts of various sources of uncertainty (financial, emotional, social), unmet needs related to uncertainty (practical, informational, communication), and recommendations for the management of uncertainty. Clinical implications and study limitations were indicated. CONCLUSIONS: Findings were situated within Mishel's Uncertainty in Illness Theory and the literature on supportive care for advanced cancer populations. Recommendations related to improving healthcare provider communication and balancing hope and expectations for treatment outcomes were highlighted. Further research is needed to investigate experiences of uncertainty in this population. Tailored interventions for uncertainty may be warranted.

The global evolution of mental health problems during the COVID-19 pandemic: A systematic review and meta-analysis of longitudinal studies.

BACKGROUND: The COVID-19 pandemic impacted mental health, but the global evolution of mental health problems during the pandemic is unknown. We conducted a systematic review and meta-analysis of longitudinal studies to evaluate the global evolution of mental health problems during the pandemic. METHODS: To conduct this systematic review, we searched for published articles from APA PsycInfo (Ovid), CINAHL (EBSCOhost), Embase (Ovid), MEDLINE (Ovid), and Web of Science. Longitudinal (at least 2 waves during the COVID-19 pandemic) and peer-reviewed articles on mental health problems conducted as from 2020 and after were included in the current study. Of 394 eligible full texts, 64 articles were included in the analysis. We computed random effects, standardized mean differences, and log odds ratio (LOR) with 95 % CIs. The meta-analysis protocol was registered with PROSPERO (CRD42021273624). RESULTS: Results showed that anxiety (LOR = -0.33; 95 % CI, -0.54, -0.12) and depression symptoms (LOR = -0.12; 95 % CI, -0.21, -0.04) decreased from baseline to follow up. However, other mental health problems showed no change. Higher prevalence rates (40.9 %; 95 % CI, 16.1 %-65.8 %) of psychological distress were found in months after July 2020, respectively, while there were no significant month differences for the prevalence of other mental health problems. Higher means of anxiety (d = 3.63, 95 % CI, 1.66, 5.61), depression (d = 3.93; 95 % CI, 1.68, 6.17), and loneliness (d = 5.96; 95 % CI, 3.22, 8.70) were observed in May 2020. Higher prevalence of anxiety, depression, and PTSD and higher means of anxiety, depression and loneliness were observed in North America. The prevalence of psychological distress and insomnia was higher in Latin America and Europe, respectively. LIMITATIONS: There is a lack of longitudinal studies in some parts of the world, such as Africa, the Caribbean, India, the Middle East, in Latin America, and Asia. CONCLUSIONS: Results indicated that anxiety and depression symptoms decreased during the COVID-19 pandemic while other mental health problems showed no statistical change. The findings reveal that mental health problems peaked in April and May 2020. Prevalence of mental health problems remains high during the pandemic and mental health prevention, promotion and intervention programs should be implemented to mitigate the consequences of the COVID-19 pandemic on the global population.
