RESUMO
OBJECTIVE: Medical staff, especially nurses, suffered great anxiety and stress from the COVID-19 pandemic, which negatively affected their sleep quality. In this study, we aimed to analyze the sleep quality of nursing staff after terminating the Zero-COVID-19 policy in China. METHODS: 506 participants were involved in our study. The Pittsburgh Sleep Quality Index (PSQI) was used to evaluate the sleep status of the participants. Binary regression was performed to evaluate the impact factors related to sleep difficulty. RESULTS: The majority of participants (96.44%) suffered from sleep disturbances. There were significant differences in age, education level and front-line activity between participants with good sleep quality and sleep difficulty. Younger age (16-25 years old) was independently associated with less sleep difficulty, while front-line activity was independently associated with severe sleep difficulty. CONCLUSION: Sleep disorder was very common among nurses after ending the Zero-COVID-19 policy in China. More front-line nurses suffered severe sleep difficulty in particular, which should be worthy of attention.
RESUMO
Objective: The aim of the study was to investigate the effectiveness of arithmetic and drawing writing on communication skills, quality of life, and cognitive impairment among people with mild and moderate dementia. Methods: We recruited 45 patients diagnosed with mild-to-moderate dementia into this study. The participants were randomly divided into arithmetic group (n = 14), drawing writing group (n = 16), and control group (n = 15). The arithmetic group was educated to understand the addition and subtraction formulas, then wrote down the correct answers between the number of 20 and 100. The drawing writing group was guided to name, draw, and write a given object. Both were trained by therapist for 12 weeks (40 minutes per week). Blinded assessors measured global cognitive function, communication skills, and quality of life using Mini-Mental State Examination (MMSE) scale, the subscales of Functional Assessment of Communication Skills scale and Quality of Life-Alzheimer's Disease scale at baseline and after 12 weeks' intervention. Results: After the 12-week intervention, the participants with mild-to-moderate dementia of the arithmetic writing group and the drawing writing group showed statistically significant improvement in communication skills and quality of life compared with the control group (social communication: 6.00 ± 0.69 vs. 6.06 ± 0.92 vs. 3.98 ± 1.33; basic needs communication: 6.32 ± 0.48 vs. 6.42 ± 0.53 vs. 4.25 ± 1.49; quality of life: 33.23 ± 5.34 vs. 34.07 ± 3.49 vs. 25.07 ± 2.60). In addition, MMSE scores of the arithmetic group tended to improve after the 12-week intervention (14.77 ± 3.06 vs. 17.31 ± 4.80, P < .01), but stabled in drawing writing group (14.27 ± 4.28 vs. 14.53 ± 5.26, P > .05) and significant decreased in the control group (13.73 ± 2.58 vs. 10.13 ± 3.23, P < .01). Conclusion: Arithmetic, drawing, and writing are effective in improving communication skills and quality of life; arithmetic also could delay the decline of cognitive function in people with mild-to-moderate dementia.
