Quality of Life in Elderly Bladder Cancer Patients Following a Cystectomy

Prognostic Significance of Lineage Diversity in Bladder Cancer Revealed by Single-Cell Sequencing

Bladder cancer is the most common malignant tumor of the urinary system. We investigated the clinical implications of cell lineages in bladder cancer by integrating single-cell and bulk transcriptome data. By investigating the single-cell transcriptional profiles of 12,424 cells from normal bladder, eleven cell types and five types of epithelial sub-population were identified. Based on the signature of cell types identified in single-cell profiles, deconvolution analysis was employed to estimate cell types and epithelial lineages in the bulk RNA sequencing bladder cancer cohort. Cancer subtypes with clinical implications were further identified based on the heterogeneity of the epithelial lineage across patients. This study suggests that the EMT-like subtype is robustly correlated with poor prognosis and the umbrella subtype is a positive factor for the patient survival. Our research has a high potential for accurate prognostic and therapeutic stratification of bladder cancer.

Effect of individualized psychological intervention on negative emotion and sleep quality of patients after bladder cancer surgery: a randomized controlled trial

Background

Bladder surgery has a negative impact on patients' mental health, sleep quality. Conventional nursing interventions failed to meet the clinical needs. Therefore, this parallel-group RCT was performed to assess the effect of individualized psychological intervention on patients' negative emotions and sleep quality after bladder cancer surgery.

Methods

Patients with bladder cancer admitted to our hospital (from September 2018 to October 2020) and underwent surgical treatment were selected as the research objects. They were randomly allocated to a parallel control group or observation group based on a computer-generated random numbers table. Because our study included behavioral intervention, blinding was not possible for participants and care givers. The control group received conventional nursing care, and the observation group received strengthened individualized psychological intervention under the nursing measures of the control group. Sleep quality, anxiety, depression, nursing compliance, and the occurrence of bladder spasm were compared between the two groups.

Results

Seventy-eight eligible patients were included and randomly divided in two groups (n=39 for each group). The intervention procedure was completed without losses and exclusions of patients after randomization. Before the intervention, the Pittsburgh Sleep Quality Index Scale and the anxiety and depression scores were comparable between the two groups (P>0.05). After the intervention, the data of the two groups were significantly improved. The sleep quality, sleep time, sleep efficiency, the time to fall asleep, hypnotic drugs, sleep disorders, daytime dysfunction, anxiety score, and depression score of the observation group were lower than those of the control group, with significant differences (P<0.05). The total nursing compliance rate of the observation group reached 100.00%, which was higher than the control group. The difference between the groups was significant (P<0.05). There was no significant difference in the incidence of bladder spasm between the two groups (P>0.05).

Conclusions

Individualized psychological intervention applied to bladder cancer surgery can effectively improve patients' negative emotions and improve their sleep quality.
