Debates persist regarding the efficacy and safety of azvudine, particularly its real-world outcomes. This study involved patients aged ≥60 years who were admitted to 25 hospitals in mainland China with confirmed SARS-CoV-2 infection between December 1, 2022, and February 28, 2023. Efficacy outcomes were all-cause mortality during hospitalization, the proportion of patients discharged with recovery, time to nucleic acid-negative conversion (T _NANC), time to symptom improvement (T _SI), and time of hospital stay (T _HS). Safety was also assessed. Among the 5884 participants identified, 1999 received azvudine, and 1999 matched controls were included after exclusion and propensity score matching. Azvudine recipients exhibited lower all-cause mortality compared with controls in the overall population (13.3% vs. 17.1%, RR, 0.78; 95% CI, 0.67-0.90; P = 0.001) and in the severe subgroup (25.7% vs. 33.7%; RR, 0.76; 95% CI, 0.66-0.88; P < 0.001). A higher proportion of patients discharged with recovery, and a shorter T _NANC were associated with azvudine recipients, especially in the severe subgroup. The incidence of adverse events in azvudine recipients was comparable to that in the control group (2.3% vs. 1.7%, P = 0.170). In conclusion, azvudine showed efficacy and safety in older patients hospitalized with COVID-19 during the SARS-CoV-2 omicron wave in China.

Objective To compare the safety and efficacy of flexible terminal suction ureteral access sheath(FTS-UAS)and negative pressure ureteral access sheath(NPUAS)in flexible ureteroscopic lithotripsy with holmium laser in treatment of renal calculi less than 2 cm in diameter.Methods A total of 68 patients(largest diameter of stone＜2 cm)with renal calculi treated in Yangjiang Hospital Affiliated to Guangdong Medical University during Nov.2022 and Aug.2023 were divided into FTS-UAS group(n=34)and NPUAS group(n=34)according to different surgical methods.The perioperative parameters and stone-free rate(SFR)were compared between the two groups.Results The average SFR on the first day after operation was significantly higher in the FTS-UAS group than in the NPUAS group[85.3％(29/34)vs.61.8％(21/34),P=0.028].The operation time was significantly lower in the FTS-UAS group than in the NPUAS group[(65.85±13.16)min vs.(75.59±20.21)min,P=0.022].For lower calyceal renal calculi,the SFR was significantly higher in the FTS-UAS group than in the NPUAS group[82.4％(14/17)vs.43.8％(7/16),P=0.032].One month after operation,the SFR was higher in the FTS-UAS group than in the NPUAS group[94.1％(32/34)vs.85.3％(29/34),P=0.452].There were no significant differences in hemoglobin reduction,serum creatinine level,postoperative complications,hospital stay and hospitalization costs between the two groups(P＞0.05).Conclusion FTS-UAS in flexible ureteroscopic lithotripsy can shorten the operation time and improve stone-clearance rate,which is safe,effective,and worthy of clinical promotion.

Objective To develop and validate a fatigue risk nomogram model in Chronic Obstructive Pulmonary Disease(COPD)patients.Methods A prospective study design was adopted,and 430 COPD patients recruited from a tertiary A hospital in Huzhou City from January to December 2022 were conveniently selected for model construction,and 129 patients were recruited from the same hospital from January to June 2023 for external validation of the model.The general information questionnaire,Pittsburgh Sleep Quality Index,2-item Generalized Anxiety Disorder Scale,2-item Patient Health Questionnaire,modified British Medical Research Council Dyspnea Index,International Physical Activity Questionnaire,and Fatigue Severity Scale were used for questionnaire survey.The risk prediction model and nomograms model were constructed using Logistic regression analysis and R 4.3.2 software,and the area under the receiver operating characteristic(ROC)curve was used to test the prediction effect of the model.Results Univariate and binary logistic regression analysis results showed that age(OR=1.095),gender(OR=2.077),dyspnea(OR=3.309),sleep quality(OR=1.979),anemia(OR=3.289),the number of acute exacerbation(OR=2.991)were independent influencing factors for fatigue in COPD patients.The internal evaluation and external validation results of the model showed that the areas under the curve are 0.912 and 0.844 respectively,and the Hosmer-Lemeshow goodness of fit test P values were 0.806 and 0.526 respectively.The average absolute errors were 0.013 and 0.019 respectively.Conclusion The COPD fatigue risk prediction model constructed in this study has good prediction effect.The visual nomogram is intuitive,convenient and easy to operate.It can provide a tool for early screening of fatigue in COPD patients.
