Objective To explore the relationship between vancomycin therapeutic drug monitoring(TDM)and short-term and long-term prognosis in patients with sepsis.Methods Clinical data of sepsis patients treated in the intensive care unit were obtained from the MIMIC-Ⅳ database.Patients were divided into the TDM group and the non-TDM group based on the status of vancomycin TDM.A 1∶1 propensity score matching(PSM)was employed.The association between vancomycin TDM and the risk of 28 d and 90 d mortality of patients before and after PSM was analyzed using Kaplan-Meier survival curves and multivariate Cox regression models.Meanwhile,the relationship between vancomycin TDM and the risk of mortality within 28 d and 90 d was investigated.Results A total of 3,525 patients were included,with 2,474 in the TDM group and 1,051 in the non-TDM group.After PSM,848 patients were included in each group.The mortality rates at 28 d and 90 d in the TDM group were lower than those in the non-TDM group both before and after PSM(P＜0.005).The Kaplan-Meier curve results showed that the survival rates at 28 d and 90 d in the TDM group were higher than those in the non-TDM group both before and after PSM(P＜0.001).Multivariate COX regression analysis showed that vancomycin TDM was an independent protective factor against mortality risk at 28 d[HR=0.74,95％CI(0.65,0.84),P＜0.001]and 90 d[HR=0.79,95％CI(0.70,0.89),P＜0.001]in sepsis patients.Conclusion Vancomycin TDM reduces the short-term and long-term mortality risk in sepsis patients and is worthy of clinical promotion and application.

Objective To investigate the clinical characteristics of women with abnormal uterine bleeding(AUB)in sub-plateau regions and analyze the factors affecting their treatment methods.Methods AUB patients who were hospitalized from Jan 1,2018 to Dec 31,2022,in a sub-plateau region(Yongping County People's Hospital of Yunnan Province)with an average altitude of 1 620 meters were selected.The general clinical characteristics of the patients were summarized,and patients were classified into two categories(with or without uterine structural lesion)and nine subtypes(PALM-COEIN)according to the FIGO recommended etiological classification guidelines.Then the patients were divided into groups based on the presence or absence of uterine structural lesions,ethnic group(Han and minority),conservative drug treatment and surgical treatment groups,blood transfusion and non-blood transfusion groups.Binary Logistic regression analysis was used to identify factors affecting treatment methods.Results A total of 481 AUB patients enrolled,and the delayed consultation rate was as high as 80.46%,and the proportion of overweight and obese patients was 49.90%,which was higher than the average level among Chinese women.The main cause was AUB-O(AUB-ovulatory dysfunction),accounting for 78.59%of cases,the proportion of patients with delayed medical treatment was higher than those without delayed medical treatment(82.17%vs.74.47%).Patients who received blood transfusion were significantly younger,had lower hemoglobin(HGB)levels,fewer pregnancies,and lower BMI compared to those in the non-blood transfusion group(P<0.05).Univariate analysis showed that the surgical treatment group had older age,longer onset time,higher HGB levels,more pregnancies and deliveries,higher BMI,a higher proportion of Han ethnicity patients,lower rates of non-blood transfusion,higher rates of hypertension,and more uterine structural lesions compared to the conservative drug treatment group.Multivariate regression analysis revealed that blood transfusion treatment reduced the probability of surgical treatment.Age and uterine structural lesions were risk factors for requiring surgical treatment,for each additional year of age,the risk of undergoing surgical treatment increased by 10%.The risk of requiring surgical treatment for patients with uterine structural lesions was 2.987 times higher than for those without.Conclusion AUB patients in this sub-plateau regions have a high rate of delayed consultation and a high proportion of overweight and obesity,with AUB-O being the primary cause.Older age and the presence of uterine structural lesions were risk factors for requiring surgical treatment.

Objective:To investigate the clinical manifestations, long-term survival, and prognosis of childhood T-cell acute lymphoblastic leukemia (T-ALL).Methods:Case summary.The clinical data of 43 T-ALL children who were diagnosed and treated in Children′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2010 to December 2021 were retrospectively analyzed.They were stratified for treatment according to the CCCG-ALL regimen, and the correlation of prognosis with the condition at initial diagnosis, early treatment response, and induced remission was analyzed.The Kaplan-Meier survival curve was used to analyze the survival rate, and the survival rates were compared between groups by the Log-rank test.The multivariate Cox regression model was used to analyze the impact of multiple factors on the long-term survival of children.Results:T-ALL patients accounted for 9.5% (43/451) of the total number of acute lymphoblastic leukemia patients admitted to the hospital at the same period.The median onset age of the 43 T-ALL patients was 7 years (1-13 years).Of the 43 patients included, 14 patients (32.6%) had concomitant mediastinal widening, 8 patients (18.6%) had concomitant giant mediastinal masses, and 4 patients (9.3%) had early precursor T-cell acute lymphoblastic leukemia (ETP-ALL) at initial diagnosis.These 43 children were treated according to the CCCG-ALL intermediate- and high-risk group regimen.Among them, 33 children (76.7%) achieved sustained remission, 5 children died, and 5 children had a relapse.As of September 30, 2024, the median follow-up time was 62 months (1-170 months), the 10-year event-free survival rate was (80.2±6.4)%, and the 10-year overall survival rate was (86.6±5.8)%.The median relapse time and 10-year cumulative relapse rate of the 5 relapsed children were 28 months (7-58 months) and (13.7±5.8)%, respectively.The relationship of prognosis with clinical characteristics at initial diagnosis and induced remission in 43 T-ALL children was analyzed.The results showed that patients aged ≥10 years, with a grade-1 non-central nervous system at initial diagnosis, ETP-ALL, abnormal chromosome number and structure, non-M1 status of bone marrow and minimal residual disease (MRD)≥ 1% on day 19 of induction treatment, and MRD ≥ 0.01% on day 46 to 55 of induction treatment had poorer long-term survival(all P<0.05).The multivariate analysis showed that age ≥10 years, ETP-ALL, and abnormal chromosome number and structure were risk factors of poor prognosis ( P=0.045, 0.030, 0.021). Conclusions:The CCCG-ALL regimen has a good overall therapeutic effect in children with T-ALL.Age ≥10 years, abnormal chromosome number and structure, ETP-ALL, grade-1 non-central nervous system at initial diagnosis, and early remission are risk factors of poor prognosis.Treatment after relapse in children with T-ALL is difficult.
