RESUMO
Purpose: Traditional Chinese Medicine (TCM) constitution and disease occurrence, development, and prognosis are interrelated. This study aimed to investigate the association between TCM constitution and the time to negative nucleic acid test results in patients with coronavirus disease 2019 (COVID-19) infected with the SARS-CoV-2 Omicron variant. Patients and Methods: We identified COVID-19 patients (≥18 years) infected with the SARS-CoV-2 Omicron variant and collected clinical data, including clinical symptoms, time to negative nucleic acid test results, and TCM constitution. Linear and logistic regression analyses explored the relationship between TCM constitution and the time to negative nucleic acid test results in patients with the COVID-19 Omicron variant. Results: We included 486 patients with COVID-19, with a mean age of 40.2 years; 321 (66.0%) men and 165 (34.0%) women. Balanced constitution accounted for 43.8%, and unbalanced constitution accounted for 56.2%. Chi-square test showed that different TCM constitutions had significant differences in the influence of clinical symptoms of COVID-19 patients (P < 0.01). After controlling for various factors, multiple linear regression analysis revealed that an unbalanced constitution was significantly positively correlated with time to negative nucleic acid test results (P < 0.05). After controlling for various factors, logistic regression analysis revealed that an unbalanced constitution was closely related to the 7-day nucleic acid test conversion rate (odds ratio (OR): 0.53, 95% confidence interval (CI): 0.36-0.80, P < 0.05). After dividing the unbalanced constitution into deficiency constitution and non-deficiency constitution, the non-deficiency constitution was closely associated with the 7-day nucleic acid test conversion rate (OR = 0.45, 95% CI: 0.28-0.74, P < 0.05). Further analysis revealed that damp-heat constitution in the non-deficiency constitution was associated with the 7-day nucleic acid test conversion rate (OR = 0.33, 95% CI: 0.18-0.60, P < 0.05). Conclusion: In patients with COVID-19, an unbalanced constitution is associated with a longer time to negative nucleic acid test results and lower 7-day nucleic acid test conversion rates.
RESUMO
Purpose: Fentanyl is approved for use in many countries as an analgesic for patients requiring mechanical ventilation. However, it redistributes and accumulates easily in the plasma because of its long half-life. Remifentanil is a short context-sensitive half-life analgesic with a lower risk of redistribution and accumulation. Materials and methods: We conducted a multicenter, randomized, double-blind, non-inferiority trial. Critically ill patients requiring mechanical ventilation were randomly allocated to receive an infusion of either remifentanil or fentanyl for up to 72 h. The primary outcome was the analgesic success rate. A 95% confidence interval lower boundary greater than -8% for the difference between the groups was considered to indicate non-inferiority between the drugs. Results: A total of 137 patients received remifentanil (69) or fentanyl (68). Remifentanil's non-inferiority to fentanyl concerning its analgesic success rate was established (difference, 5.97%; 95% confidence interval: -3.99% to 16.35%). Mechanical ventilation duration, extubation duration, successful extubation, intensive care unit discharge, intensive care unit length of stay, and adverse events did not differ significantly between the two groups. Conclusions: Remifentanil was non-inferior to fentanyl regarding the analgesic success rate in critically ill patients requiring mechanical ventilation.
