The purpose of the study was to examine grade-level differences in coping behaviors among adolescents using a probabilistic multidimensional scaling (MDS) single-ideal-point model. Using data from students in middle school and at college, this article illustrated the MDS single-ideal-point model as an alternative to examine students’ typical coping behaviors.

MicroRNAs (miRNAs) play critical roles in the progression of laryngeal cancer (LC). In this study, we aimed to investigate whether miR-149 is associated with the prognosis of patients with LC. A total of 97 laryngeal squamous cell carcinoma patients who underwent tumor resection were included in our follow-up study. In vitro studies was performed in cancer cell line Hep-2 to explore the antitumor role of miR-149 in LC. We found that the expression of miR-149 was significantly lower in tumor tissues, compared with vocal cord polyp tissues (P<0.05). Kaplan-Meier analysis revealed that miR-149 expression status is significantly associated with survival duration (log rank test, P<0.05), and multivariate Cox regression analysis revealed that patients with low miR-149 expression had shorter survival times compared with patients with high miR-149 expression. In vitro studies revealed that the exogenous expression of miRNA-149 inhibits the proliferation of human Hep-2 cells and induces cell apoptosis. Our study suggests that miR-149 expression in laryngeal squamous cell carcinoma tissues is critically associated with the prognosis of patients, and the ectopic expression of miR-149 in Hep-2 cells inhibits proliferation and cell cycle progression.

Self-management is essential for patients who require regular hemodialysis treatment. This study aimed to explore the relationships between social support, sense of coherence (SOC), and self-management in hemodialysis patients and to examine whether SOC plays a mediating role. In a cross-sectional study, 402 hemodialysis patients from four tertiary hospitals were recruited. Data were analyzed using structural equation modeling. Social support, SOC, and self-management were significantly correlated with each other. The proposed model provided a good fit to the data. Social support had a direct effect on self-management and SOC, partially mediated the effect of social support on self-management (β = 0.248, p = 0.001). Social support and SOC explained 69% of the variance in self-management. Our findings indicate that health care providers can enhance social support with an emphasis on strengthening SOC strategies to better improve self-management in hemodialysis patients.

This cross-sectional study assessed the overall symptom burden, including the prevalence, frequency, severity, and distress of symptoms among hemodialysis patients, and explored the relationship between demographic characteristics, clinical variables, self-management, sense of coherence, social support, and symptom burden in these patients. Herein, a regression analysis was performed to determine associations with symptom burden. The mean score of symptom burden among the participants (n = 382) was 74.12, with an average number of 12 symptoms. The analysis revealed that self-management, sense of coherence, and social support were negatively associated with the overall symptom burden. The multiple regression model showed that 48.6% of the variance in symptom burden was explained by meaningfulness, emotional management, daily urine output, subjective support, gender, and manageability. These findings contribute to the knowledge of symptom burden among hemodialysis patients and some new predictors (self-management, sense of coherence, and social support) of their symptom burden.
