Efficacy，safety and cost-effectiveness evaluation of voriconazole original and generic drugs / 中国药房

OBJECTIVE To evaluate the efficacy， safety and cost-effectiveness of generic drugs and original drugs of voriconazole. METHODS The information of patients who used voriconazole generic drugs selected in National Centralized Drug Procurement （generic drug group） or non-selected original drugs （original drug group） in the treatment of fungal infection was collected from the our hospital. The propensity score matching was carried out to eliminate bias. The comprehensive efficacy was evaluated according to clinical efficacy， image findings and microbiological test， and stratified analysis of different populations was conducted based on fungal species， underlying diseases， etc.， the efficacy of different stratifications was evaluated. Evaluation of safety was performed by using the incidence of adverse reactions. The total cost， defined daily doses （DDDs） and defined daily dose cost （DDDc） were used to evaluate the cost-effectiveness. RESULTS A total of 436 patients were included， and there were 190 patients in each group after matching. In terms of efficacy， the effective rates of voriconazole generic drugs and original drugs were 62.63% and 59.47% （P＝0.528）； in terms of safety， the incidence of adverse reactions caused by generic drugs and original drugs of voriconazole was 13.68% and 7.89%， respectively（P＝0.069）. In terms of cost-effectiveness， the average total cost of generic drugs was 4 636.26 yuan， and that of original drugs was 8 613.20 yuan （P＜0.001）. After the implementation of National Centralized Drug Procurement， replacement rate of generic drugs increased to 87.30%， and DDDc decreased by 59.08%. CONCLUSIONS The efficacy and safety of voriconazole generic drugs are similar to those of original drugs in the treatment of fungal infection， and it is more cost-effective in terms of treatment cost.

Association between overtime work and work-related musculoskeletal disorders among male employees in the automobile manufacturing industry / 中国职业医学

ObjectiveTo explore the impact of overtime work on work-related musculoskeletal disorders in male employees in the automobile manufacturing industry. Methods A total of 1 731 male employees with more than one year of working experience from an automobile manufacturing industry were selected as the research subjects using judgment sampling method. The Musculoskeletal Disorder Questionnaire was used to investigate the prevalence of musculoskeletal disorder. Employees were divided into control group and overtime group, and a 1∶1 matching was performed using propensity score matching method, and 573 pairs were successfully matched. The prevalence of WMSDs in various body parts was compared between the two groups. Results The overtime working rate of the research subjects was 34.2%, and the prevalence of WMSDs was 57.1%. Overtime work increased the risk of WMSDs in the neck, shoulders, upper back, lower back, ankle/feet, and overall body of the workers (all P<0.05), with the odd ratio and 95% confidence interval of 1.43 (1.10-1.85), 1.38 (1.06-1.80), 1.42 (1.07-1.89), 1.28 (1.01-1.62), 1.37 (1.01-1.87), and 1.49 (1.17-1.89), respectively. However, there was no association between overtime work and the risk of WMSDs in the elbows, hands/wrists, hips, and knees of the subjects (all P>0.05). Conclusion Overtime work increases the risk of WMSDs in the neck, shoulders, upper back, lower back, ankles/feet, and overall body of male employees in the automobile manufacturing industry. Enterprises should improve labor organization, reduce overtime work, and protect the health of workers.

The influence of renally inappropriate medication on the frailty of elderly patients with diabetes / 中国药房

OBJECTIVE To investigate the effects of renally inappropriate medication （RIM） on the frailty of elderly patients with diabetes. METHODS The data of elderly patients with diabetes mellitus admitted to a third-grade class A hospital in Yunnan province from January to December 2022 were collected， and Beers criteria （2019 edition） and Chinese version of FRAIL scale were used to evaluate RIM and the frailty of the patients； the patients were divided into the trial group （with RIM） and the control group （without RIM） according to whether there was RIM. The propensity score matching was used to balance confounding factors between two groups， and the influence of RIM on the frailty of elderly diabetic patients was analyzed by the Logistic regression model. RESULTS Among the 367 patients， 80 patients （21.80%） had RIM， the drugs involved RIM were spironolactone （82.56%）， rivaroxaban （13.95%） and gabapentin （3.49%）. After reaching the balance between groups using the propensity score matching method， the incidence of frailty was 77.94% in trial group and 27.94% in control group （P＜0.001）； the difference was not statistically significant in other confounding factors between the two groups （P＞0.05）. Results of Logistic regression analysis showed that the risk of frailty in the experimental group was 3.118 times that of the control group （odds ratio was 3.118，95% confidence interval was 1.758-5.530， P＜0.001）. CONCLUSIONS RIM is a risk factor for the frailty of elderly patients with diabetes， which can be considered as an indicator for early identification and screening of the frailty of elderly diabetes patients.

The relationship between mean daily step counts and pulmonary complications after thoracoscopic lobectomy in elderly patients: A propensity score matching study / 中国胸心血管外科临床杂志

@#Objective     To investigate the relationship between preoperative mean daily step counts and pulmonary complications after thoracoscopic lobectomy in elderly patients. Methods     From 2018 to 2021, the elderly patients with pulmonary complications after thoracoscopic lobectomy were included. A 1∶1 propensity score matching was performed with patients without pulmonary complications. The clinical data were compared between the two groups. Results    Totally, 100 elderly patients with pulmonary complications were enrolled, including 78 males and 22 females, aged 66.4±4.5 years. And 100 patients without pulmonary complications were matched, including 71 males and 29 females aged 66.2±5.0 years. There was no significant difference in the preoperative data between the two groups (P>0.05). Compared to the patients with pulmonary complications, the ICU stay was shorter (8.1±4.4 h vs. 12.9±7.5 h, P<0.001), the first out-of-bed activity time was earlier (8.8±4.5 h vs. 11.2±6.1 h, P=0.002), and the tube incubation time was shorter (19.3±9.2 h vs. 22.5±9.4 h, P=0.015) in the patients wihout pulmonary complications. There was no statistical difference in other perioperative data between the two groups (P>0.05). The mean daily step counts in the pulmonary complications group were significantly less than that in the non-pulmonary complications group (4 745.5±2 190.9 steps vs. 6 821.1± 2 542.0 steps, P<0.001). The daily step counts showed an upward trend for three consecutive days in the two groups, but the difference was not significant. Conclusion     The decline of preoperative mean daily step counts is related to pulmonary complications after thoracoscopic lobectomy in elderly patients. Recording daily step counts can promote preoperative active exercise training for hospitalized patients.

The association of intraoperative positive end-expiratory pressure with pulmonary complications after thoracoscopic lung surgery: A propensity score-matching study / 中国胸心血管外科临床杂志

@#Objective To evaluate the correlation between positive end-expiratory pressure (PEEP) level and postoperative pulmonary complications (PPCs) in patients undergoing thoracoscopic lung surgery. Methods The clinical data of patients who underwent elective thoracoscopic lung surgery at West China Hospital of Sichuan University from January 2022 to June 2023 were retrospectively analyzed. Patients were divided into 2 groups according to intraoperative PEEP levels: a PEEP 5 cm H2O group and a PEEP 10 cm H2O group. The incidence of PPCs in the two groups after matching was compared using a nearest neighbor matching method with a ratio of 1∶1, setting the clamp value as 0.02. Results A total of 538 patients were screened, and after propensity score-matching, a total of 229 pairs (458 patients) were matched, with an average age of 53.9 years and 69.4% (318/458) females. A total of 118 (25.8%) patients had PPCs during hospitalization after surgery, including 60 (26.2%) patients in the PEEP 5 cm H2O group and 58 (25.3%) patients in the PEEP 10 cm H2O group, with no statistically significant difference between the two groups [OR=0.997, 95%CI (0.495, 1.926), P=0.915]. Multivariate logistic regression analysis showed that PEEP was not an independent risk factor for PPCs [OR=0.920, 95%CI (0.587, 1.441), P=0.715]. Conclusion For patients undergoing thoracoscopic lung surgery, intraoperative PEEP (5 cm H2O or 10 cm H2O) is not associated with the risk of PPCs during hospitalization after surgery, which needs to be further verified by prospective, large-sample randomized controlled studies.

@#Objective To compare the clinical efficacy of open and laparoscopic left hepatectomy for the treatment of left intrahepatic bile duct stones.Methods The clinical data of 136 patients treated with hepatectomy admitted to the Department of General Surgery of the Second Hospital of Yinzhou District,Ningbo from January 1,2016 to January 1,2022 were retrospectively collected.132 patients treated with left hepatectomy were included,and the propensity score matching method was used to perform 1∶1 matching between the open left lobe hepatectomy(OLH)and laparoscopic left lobe hepatectomy(LLH)groups.Forty-seven patients were matched in each group.The main observations were:operative time,intraoperative bleeding,intraoperative blood transfusion rate,postoperative hospital stay,complication rate,biliary fistula rate,stone removal rate and stone recurrence rate.Results The LLH group had a shorter postoperative hospital stay,a lower postoperative complication rate and a lower postoperative biliary fistula rate(P<0.05).There was no statistically significant difference in the initial stone removal rate,final stone removal rate and stone recurrence rate between the two groups.Multifactorial analysis showed that open surgery and postoperative complications were independent risk factors for prolonge postoperative hospital stay.Open surgery was an independent risk factor for postoperative biliary fistula;left extrahepatic lobectomy,postoperative biliary fistula and combined multiple stones were independent risk factors for stone independent risk factors for recurrence.Conclusion Laparoscopic left hepatectomy for left intrahepatic bile duct stones is safe and effective.Postoperative biliary fistula and the combination of multiple stones were independent risk factors for recurrence of intrahepatic bile duct stones after surgery.

Blood transfusion is correlated with elevated adult all-cause mortality and cardiovascular mortality in the United States: NHANES 1999 to 2018 population-based matched propensity score study

Abstract Background and aims The association of blood transfusion with an increase in medium- and short-term mortality in specific populations has been confirmed. However, the correlation between blood transfusion and long-term mortality in the general population remains unclear. This cohort study evaluated the correlation between blood transfusion and overall and cause-specific mortality in the general American adult population. Methods The authors utilized 10 sets of 2-year cycle data (1999-2018) from the National Health and Nutrition Examination Survey on the outcomes of adults who did and did not receive blood transfusions. Propensity score-matching (1:1) was performed based on age, sex, race, education level, marital status, poverty-income ratio, arteriosclerotic cardiovascular disease, cancer, anemia, hypertension, and diabetes status. After controlling for demographic characteristics and clinical risk factors, Cox regression analysis was performed to evaluate the correlation between blood transfusion and all-cause and cause-specific mortality. Results The study included 48,004 adult participants. The risk of all-cause mortality increased by 101 % with blood transfusion, and the risk of cardiovascular mortality increased by 165 %. After propensity score-matching, 6,116 pairs of cases were retained, and the risk of all-cause mortality increased by 84 % with blood transfusion, and the risk of cardiovascular mortality increased by 137 %. The sensitivity analysis results were robust. Conclusions In the general American population, blood transfusion significantly impacts long-term all-cause and cardiovascular mortality and may be an unacknowledged risk factor for death. Thus, the effective management of blood transfusion in the general population may be beneficial.

The correlation between cardiac polyps and abnormal gastroesophageal flap valve: a retrospective case-control study / 中华消化内镜杂志

Objective:To investigate the correlation between cardiac polyps and gastroesophageal flap valve (GEFV).Methods:The clinical, endoscopic and pathological data of 349 patients with cardiac polyps (the cardiac polyp group) visiting Affiliated Hospital of Yangzhou University from January 1, 2016 to December 31, 2021 were retrospectively collected, and the same number of non-cardiac polyp patients (the non-cardiac polyp group) were matched in the same period as control according to the propensity score. The clinical, endoscopic and pathological data of the two groups were compared.Results:After matching with propensity score, there were 296 patients in each group, with no significant differences in smoking, acid reflux, heartburn, Helicobacter pylori infection, bile reflux, reflux esophagitis or pancreatitis between the two groups ( P>0.05). Compared with the non-cardiac polyp group, the risk of cardiac polyps increased in GEFV Ⅱ patients ( OR=3.046, 95%CI: 2.100-4.419, P<0.001) and GEFV Ⅲ patients ( OR=4.202, 95%CI: 2.299-7.681, P<0.001). Compared with the non-cardiac polyp group, the risk of cardiac polyps increased in patients with GEFV abnormalities ( OR=2.822, 95%CI: 1.615-4.931, P<0.001). GEFV abnormalities was associated with the cardiac polyp site ( χ2=22.169, P=0.003) and was not significantly associated with cardiac polyp size, number, morphology, intestinal metaplasia of the surrounding mucosa or intraepithelial neoplasia ( P>0.05). Conclusion:The occurrence of cardiac polyps is related to GEFV, and the patients with GEFV abnormalities are more likely to develop cardiac polyps.

Effect of preoperative application of dexmedetomidine on atrial fibrillation after coronary artery bypass grafting: A propensity score-matching analysis / 中国胸心血管外科临床杂志

@#Objective To evaluate the incidence of postoperative atrial fibrillation (POAF) after dexmedetomidine and diazepam in patients undergoing coronary artery bypass grafting (CABG). Methods A retrospective cohort study was conducted in the patients who underwent CABG in the General Hospital of Northern Theater Command from October 2020 to June 2021. By propensity score-matching method, the incidence of POAF after dexmedetomidine and diazepam application in patients undergoing CABG was evaluated. Results Finally 207 patients were collected, including 150 males and 57 females, with an average age of 62.02±8.38 years. Among the 207 patients, 53 were treated with dexmedetomidine and 154 with diazepam before operation. There was a statistical difference in the proportion of hypertension patients and smoking patients between the two groups before matching (P<0.05). According to the 1∶1 propensity score-matching method, there were 53 patients in each of the two groups, with no statistical difference between the two groups after matching. After matching, the incidence of POAF in the dexmedetomidine group was lower than that in the diazepam group [9.43% (5/53) vs. 30.19% (16/53), P=0.007]. There was no death in the two groups during hospitalization, and there was no statistical difference in the main adverse events after operation. The ICU stay (21.28±2.69 h vs. 22.80±2.56 h, P=0.004) and mechanical ventilation time (18.53±2.25 h vs. 19.85±2.01 h, P=0.002) in the dexmedetomidine group were shorter. Regression analysis showed that age, smoking and diabetes were related to the increased incidence of POAF (P<0.05), and preoperative use of dexmedetomidine was associated with a reduced incidence of POAF (P=0.002). Conclusion For patients undergoing CABG, the incidence of POAF with dexmedetomidine before operation is lower than that with diazepam. Preoperative application of dexmedetomidine is the protective factor for POAF, and old age, smoking and diabetes are the risk factors for POAF.

Additional tricuspid valve annuloplasty versus isolated closure for atrial septal defect with secondary moderate to severe tricuspid regurgitation: A propensity score matching study / 中国胸心血管外科临床杂志

@#Objective To compare the efficacy of additional tricuspid valve annuloplasty (TVP) and isolated closure for atrial septal defect (ASD) with moderate to severe tricuspid regurgitation (TR). Methods Clinical data of the patients diagnosed with ASD combined with secondary moderate to severe TR and treated in our hospital from January 2009 to June 2020 were retrospectively analyzed. Patients were divided into a TVP group and a non-TVP group based on whether TVP was performed simultaneously. The baseline data of two groups were matched with a ratio of 1∶1 propensity score. Results A total of 32 pairs from 257 patients were successfully matched. In the TVP group, there were 24 females and 8 males with an average age of 44.0±13.1 years. In the non-TVP group, there were 28 females and 4 males with an average age of 44.5±11.6 years. The TR area and estimated pulmonary artery pressure in the two groups were significantly decreased compared with preoperation (all P<0.001). The TR area (P=0.001) and the estimated pulmonary artery pressure (P=0.002) were decreased more significantly in the TVP group than those in the non-TVP group. Linear regression analysis showed that age and preoperative TR area had a positive correlation with TR area at follow-up (β=0.045 and 0.259, respectively, both P<0.05), while additional TVP had a negative correlation (β=–1.542, P=0.001). Conclusion Additional TVP can significantly reduce the TR area and pulmonary artery pressure, and elderly patients with severe TR before surgery should actively receive TVP.

Mid-and long-term state after total hip arthroplasty versus hemiarthroplasty for femoral neck fractures in the elderly:evaluation using propensity score matching method / 中国组织工程研究

BACKGROUND:Arthroplasty is the primary treatment for displaced femoral neck fractures in the elderly,and the choice of total hip arthroplasty versus hemiarthroplasty is currently the subject of considerable debate. OBJECTIVE:To compare the mid-and long-term survival status of total hip arthroplasty versus hemiarthroplasty under a direct anterior approach for displaced femoral neck fractures in the elderly based on the propensity score matching method. METHODS:One hundred and forty-seven elderly patients(≥65 years of age)with displaced femoral neck fractures were admitted from January 2016 to January 2021,of whom 88 had total hip arthroplasty(total hip arthroplasty group)and 59 had artificial femoral head replacement(hemiarthroplasty group).For the patients'preoperative comorbidities,the age-corrected Charlson Comorbidity Scale was used to quantify the scores and calculate patient frailty.The propensity score matching method was used to match the two groups 1:1 and to compare the operation time,bleeding,postoperative hospitalization time,hospitalization cost,nutritional index,postoperative complications,and mortality between the two groups after matching.Postoperative survival time was determined by Kaplan-Meier Survival analysis. RESULTS AND CONCLUSION:(1)After propensity score matching,a total of 42 matched pairs were successful in both groups,and the preoperative data of patients in both groups were balanced and comparable after matching(P>0.05).(2)Compared with the hemiarthroplasty group,operation time(79.71 minutes vs.59.07 minutes,P<0.001),bleeding volume(839.64 mL vs.597.83 mL,P=0.001),and hospitalization cost(56 508.15 yuan vs.41 702.85 yuan,P<0.001)were significantly higher in the total hip arthroplasty group.However,the mortality rate was lower in the total hip arthroplasty group than in the hemiarthroplasty group(36%vs.57%,HR=0.44,95%CI:0.23-0.87,P=0.018),and the mean survival time was longer in the total hip arthroplasty group than in the hemiarthroplasty group(59.4 months vs.43.7 months,P=0.024).(3)There were no statistically significant differences in postoperative hospitalization time,preoperative and postoperative nutritional indicators,and overall postoperative complication rate between the two groups(P>0.05).However,in terms of postoperative pain,the incidence of pain was significantly higher in the hemiarthroplasty group than that in the total hip arthroplasty group(24%vs.7%,P=0.035).(4)Overall,total hip arthroplasty has a better prognosis for survival,while hemiarthroplasty is more appropriate for patients with poor physical fitness.At the same time,postoperative pain may largely affect the quality and survival time of patients after hip arthroplasty.

Objective To investigate the correlation of triglyceride glucose product index(TyG index)with the diagnosis of coronary heart disease(CHD)and the severity of coronary stenosis.Methods A total of 404 patients who received coronary angiography for the first time in Xinhua Hospital Affiliated to Shanghai Jiaotong University School of Medicine with unexplained chest pain from December 2021 to October 2022 were included.All subjects were divided into CHD group(n=216)and non-CHD group(n=188).General clin-ical data,laboratory information and coronary angiography results of all participants were collected.The CHD group(n=123)and the non-CHD group(n=123)were obtained after the propensity score matching(PSM).Patients in CHD group were further divided into low Gensini score(Gensini score＜35,n=59)group and high Gensini score(Gensini score ≥ 35,n=64)group according to the me-dian Gensini score.The differences among groups were compared and the relation between TyG index and the severity of coronary artery stenosis was analyzed.Then the predictive value of TyG index for CHD and the severity of coronary lesion was evaluated by Logistic regres-sion and receiver operating characteristic(ROC)curve.Results After PSM,the differences in TyG index,TG,FPG,HDL-C in CHD group were statistically significant compared with the non-CHD group(P＜0.05).Multivariate Logistic regression analysis showed that the TyG index was an independent risk factor for CHD.Spearman correlation analysis showed that the TyG index was positively correlated with the Gensini score(r=0.618,P＜0.001).The ROC curve analysis showed that the area under the curve(AUC)of the TyG index predicting a high Gensini score was 0.873(95％CI:0.802-0.943,P＜0.001).A cut-off value was 7.08,and the sensitivity and specificity were 95.2％and 67.3％,respectively.Conclusion TyG index can be used as an independent risk factor for CHD,and has certain predictive value for the severity of coronary stenosis.

A comparative study of different surgical method for stage ⅠA non-small cell lung cancer / 局解手术学杂志

Objective To compare the clinical efficacies of video-assisted thoracoscopic segmentectomy versus lobectomy for early-stage non-small cell lung cancer.Methods The clinical data of 234 patients with stage ⅠA non-small cell lung cancer and undergoing different surgical methods under video-assisted thoracoscopy admitted to Chongqing Dianjiang General Hospital were retrospectively analyzed,and the patients were divided into the lung segment group and the lung lobe group according to their surgical methods.The clinical characteristics of the patients in the two groups were balanced by a 1-to-1 ratio matching through the propensity score matching method,and each group finally included 63 cases.The perioperative indicators containing operation time,intraoperative blood loss,postoperative thoracic drainage tube indwelling time,thoracic drainage volumes 24 hours and 48 hours after operation and postoperative hospital stay were compared of patients between the two groups.The incidence of postoperative complications such as air leakage>6 days,pulmonary infection,atelectasis,hemoptysis,and hoarseness in the two groups was collected.Results There was no significant difference in the operation time,intraoperative blood loss,thoracic drainage volumes 24 hours and 48 hours after operation,postoperative thoracic drainage tube indwelling time or incidence of postoperative complications of patients between the two groups(P>0.05).The postoperative hospital stay of patients in the lung segment group was shorter than that in the lung lobe group,with statistically significant difference(P=0.003).Conclusion For patients with stage ⅠA non-small cell lung cancer,video-assisted thoracoscopic segmentectomy has similar perioperative efficacy to lobectomy,while segmentectomy has a more significant advantage in shortening the hospital stay.

Predictive value of von Willebrand factor for venous thromboembolism in critically ill patients based on propensity score matching / 中华危重病急救医学

Objective:To analyze the predictive value of von Willebrand factor (vWF) for venous thromboembolism (VTE) of patients in intensive care unit (ICU) by using propensity score matching (PSM).Methods:Patients admitted to ICU of the Second Affiliated Hospital of Kunming Medical University from December 2020 to June 2022 who stayed in ICU for ≥72 hours and underwent daily bedside vascular ultrasound screening were included. Baseline data such as age, gender, primary disease, and chronic comorbidities were collected. Coagulation indexes before admission to ICU and 24 hours and 48 hours after ICU admission were collected, including prothrombin time (PT), activated partial thromboplastin time (APTT), thrombin time (TT), international normalized ratio (INR), fibrinogen (Fib), fibrin monomer (FM), vWF, D-dimer, antithrombin Ⅲ (ATⅢ), etc. Patients were divided into VTE group and non-VTE group according to whether they had VTE or not [diagnosis of VTE: patients underwent daily ultrasound screening of bedside blood vessels (both upper and lower limbs, visceral veins), and those suspected of having thrombosis were confirmed by ultrasonographer or pulmonary angiography]. Using PSM analysis method, the VTE group was used as the benchmark to conduct 1 : 1 matching of age, whether there was malignant tumor, whether there was infection, whether there was diabetes, and coagulation indicators before admission to ICU. Finally, the cases with balanced covariates between the two groups were obtained. The risk factors of VTE were analyzed by multivariate Logistic regression analysis. Receiver operator characteristic curve (ROC curve) was drawn to evaluate the predictive value of vWF in the occurrence of VTE in critically ill patients.Results:A total of 120 patients were enrolled, of which 18 (15.0%) were diagnosed with VTE within 72 hours after admission to ICU, and 102 (85.0%) were not found to have thrombus in ICU. Before PSM, there were significant differences in age, gender, proportion of malignant tumor and infection, and coagulation indexes between VTE group and non-VTE group. After PSM, 14 pairs were successfully matched, and the unbalanced covariables between the two groups reached equilibrium. Multivariate Logistic regression analysis showed that vWF was an independent risk factor for VTE at 48 hours after ICU admission in critically ill patients [odds ratio ( OR) = 1.165, 95% confidence interval (95% CI) was 1.000-1.025, P = 0.004]. ROC curve analysis showed that the area under the ROC curve (AUC) of vWF at 48 hours after ICU admission for predicting VTE was 0.782, 95% CI was 0.618-0.945, P = 0.007. When the optimal cut-off value was 312.12%, the sensitivity was 67.7% and the specificity was 93.0%. Conclusion:Dynamic monitoring of vWF is helpful to predict the occurrence of VTE in ICU patients, and vWF at 48 hours after ICU admission has certain value in predicting the occurrence of VTE.
