OBJECTIVE To systematically evaluate medication risk prediction models for hospitalized adult patients and provide references for their development and clinical application. METHODS Databases including PubMed， Embase， Web of Science， CNKI， Wanfang data， VIP and CBM were searched for studies on medication risk prediction models from their inception to May 2024. After screening the literature， extracting data， and evaluating the quality of the literature， descriptive analysis was performed on the results of the included studies. RESULTS A total of 13 studies were included， involving 12 models. Nine studies used Logistic regression algorithm for modeling， and the number of included predictive factors ranged from 3 to 11； the area under the receiver operating characteristic curve ranged from 0.65 to 0.865. The literature quality evaluation results showed that 10 studies had high risk of bias； 10 studies had high applicability risk. A total of 31 predictive factors were extracted， including 15 items of basic patient information， 3 test indicators， and 5 items of medication information， and 8 others. CONCLUSIONS The existing medication risk prediction models for hospitalized adult inpatients are mainly Logistic regression algorithm， with predictive factors mainly focusing on basic indicators such as demographics. The overall prediction performance of the models needs to be improved， and the overall risk of bias is relatively high.

Ceftazidime-avibactam （CAZ/AVI）is a novel β-lactam antibiotic with broad-spectrum antibacterial activity and good tolerability. However， the physiological and pathological differences in special populations [e.g. augmented renal clearance （ARC） patients， undergoing continuous renal replacement therapy （CRRT） patients， neonates and children， obese patients， undergoing extracorporeal membrane oxygenation （ECMO） patients， elderly patients and liver dysfunction patients] may affect the pharmacokinetic （PK） properties of CAZ/AVI， leading to treatment failure. At present， there is currently a lack of corresponding guidelines or consensus on dose adjustment of CAZ/AVI in special populations. This article summarizes the research on PK/ pharmacodynamic （PD） characteristics and dose adjustment of CAZ/AVI in special populations and recommends the following dosing regimens： for ARC patients， the recommended dose is 2.5 g， q8 h； for undergoing CRRT patients with infections caused by sensitive strains （i.e. MIC＜4 mg/L） and infections at sites where hydrophilic antibiotics distribute well， a dose of 1.25 g， q8 h may be used； for undergoing CRRT patients with less sensitive strains or sites with poorer drug distribution， a dose of 2.5 g， q8 h or continuous infusion may be considered； for children aged 6 months to ＜18 years with normal or mildly impaired renal function， a dose of 62.5 mg/kg， q8 h is infused for 2 h （maximum dose not exceeding 2.5 g per dose）； for infants aged 3～6 months with normal or mildly impaired renal function， a dose of 50 mg/kg， q8 h is infused for 2 h； for obese patients， the recommended dose is 2.5 g， q8 h， with therapeutic drug monitoring recommended；undergoing ECMO patients， elderly patients， and those with impaired liver function may also use the recommended dose of 179368757@qq.com 2.5 g， q8 h.

[Objective] To investigate the pathological characteristics of false-positive lesions of prostate cancer on ⁶⁸Ga-PSMA-11 PET/CT based on the pathology of whole mount specimens, in order to more accurately assess the degree of malignancy within the prostate tissue and avoid overdiagnosis and unnecessary treatment. [Methods] A total of 77 patients who underwent ⁶⁸Ga-PSMA-11 PET/CT before radical prostatectomy in Nanjing Drum Tower Hospital during Jan.2018 and Dec.2022 were retrospectively analyzed.The pathology of whole mount specimens was detected.Two nuclear physicians examined all imaging plates without knowing the pathological results.Two pathological physicians completed all pathological diagnosis without knowing the imaging results.The pathological characteristics of false-positive lesions were determined by matching ⁶⁸Ga-PSMA-11 PET/CT and pathological specimens.To analyze the pathological features of false-positive lesions, true-negative lesions were randomly delineated and defined.The pathological features of false-positive and true-negative lesions were analyzed and compared using Fisher exact test. [Results] After the imaging and pathological sections were matched, 21(16.3%) false-positive lesions were identified.The pathological characteristics of the 21 false-positive lesions were as follows: 16 (76.2%) simple atrophy with cyst formation, 3(14.3%) prostatic nodular hyperplasia, and 2(9.5%) inflammation.The pathological characteristics of 21 true-negative lesions were: 13(61.9%) normal glands, 5(23.8%) prostatic nodular hyperplasia and 3(14.3%) simple atrophy with cyst formation.Fisher exact test showed that the proportion of simple atrophy with cyst formation in the pathological features of false-positive lesions and true-negative lesions was statistically significant (76.2% vs.14.3%, P<0.001). [Conclusion] Simple atrophy with cyst formation may be a characteristic pathological type of the false-positive lesions of prostate cancer on ⁶⁸Ga-PSMA-11 PET/CT.

Objective This article aims to investigate the association between hypertension and the risk of GSD by conducting a national multicenter study,a systematic review,and a meta-analysis.Methods The study was conducted in three stages.In the first stage,subjects were recruited for health examination in four hospitals in Chengdu,Tianjin,Beijing,and Chongqing,China,from 2015 to 2020,and the multivariate logistic regression analysis was used to investigate the association between hypertension and the risk of GSD in each center.In the second stage,Embase,PubMed,Wanfang Data,VIP,and CNKI databases were searched for related studies published up to May 2021,and a meta-analysis was conducted to further verify such association.In the third stage,the random effects model was used for pooled analysis of the results of the multicenter cross-sectional study and the findings of previous literature.Results A total of 633 948 participants were enrolled in the cross-sectional study,and the prevalence rate of GSD was 7.844%.The multivariate logistic regression analysis showed that hypertension was positively associated with the risk of GSD(P＜0.05).Subgroup analysis showed that there was no significant difference in the association between hypertension and GSD between individuals with different sexes,ages,and subtypes of GSD.A total of 80 articles were included in the systematic review and the meta-analysis,and the results showed that the risk of GSD was increased by 1.022 times for every 10 mmHg increase in diastolic pressure and 1.014 times for every 10 mmHg increase in systolic pressure.Conclusion Hypertension significantly increases the risk of GSD,and the findings of this study will provide a basis for the etiology of GSD and the identification of high-risk groups.

Objective:To evaluate the diagnostic value of targeted biopsy of secondary lesion (SL) in systematic biopsy (SB) combined targeted biopsy for clinically significant prostate cancer (CsPCa).Methods:A retrospective analysis was conducted on the data of patients who underwent systematic biopsy combined target biopsy at Nanjing Drum Tower Hospital from January 2021 to February 2023, and they had at least two Prostate Imaging-Reporting and Data System (PI-RADS) score ≥3 lesions on prostate magnetic resonance imaging. The study included patients with a median age of 70 (65, 76) years old, median prostate specific antigen (PSA) was 9.1 (5.96, 13.62) ng/ml, median prostate volume was 39.1 (29.27, 53.25) ml, and median PSAD was 0.2 (0.15, 0.38) ng/ml 2.The index lesion (IL) was defined as the one with the highest PI-RADS score and SL was defined as the one with the second-highest PI-RADS score. If the two lesions had the same PI-RADS score, the one with larger maximum diameter was IL and the other one was SL. The median maximum diameter of IL and SL were 1.3 (1.06, 1.66) cm and 0.9 (0.69, 1.20) cm, respectively. The median maximum diameter ratio of IL and SL was 1.48 (1.10, 1.91), and the median maximum diameter difference of IL and SL was 0.9 (0.20, 1.89) cm. The IL in peripheral zone was found in 238 patients (62.63%) and SL in peripheral zone was found in 255 patients (67.10%). There were 204 patients (53.68%) having both IL and SL on the same side of prostate. According to the combination of PI-RADS scores of IL and SL, patients were categorized into various groups: 96 patients (25.26%) with IL3 and SL3, 79 (20.78%) with IL4 and SL3, 98 (25.78%) with IL4 and SL4, 21 (5.52%) with IL5 and SL3, 76 (20.0%) with IL5 and SL4, and 10 (2.63%) with IL5 and SL5. Targeted biopsy was performed on at least two of the most significant lesions. Comparison was performed in the detection rate of CsPCa between SB+ IL+ SL and SB+ IL (SL was omitted). To explore the factors influencing the detection rate of CsPCa, a multivariate logistic regression analysis was used. Results:The detection rate of CsPCa in this study was 78.95% (300/380) based on SB+ IL+ SL. After omitting SL target biopsy, the detection rate of CsPCa was 78.16% (297/380, P>0.05) under the condition of SB+ IL. No significant differences were noted between the two groups. The multivariate logistic regression analysis showed that PSA ( OR=1.11, 95% CI 1.05-1.20, P<0.01), prostate volume ( OR=0.98, 95% CI 0.96-0.99, P<0.01), SL maximum diameter ( OR=0.19, 95% CI 0.08-0.50, P<0.01), ratio of IL and SL maximum diameter ( OR=0.34, 95% CI 0.16-0.68, P<0.01), difference of IL and SL maximum diameter ( OR=1.50, 95% CI 1.10-2.29, P<0.05), and PI-RADS score group of IL and SL (IL3 vs. SL3 as the reference, IL4 vs. SL3 OR=4.79, 95% CI 2.21-10.91, P<0.01, IL4 vs. SL4 OR=23.11 95% CI 8.09-85.28, P<0.01, IL5 vs. SL3/4/5 OR=15.28 95% CI 5.21-48.55, P<0.01) were the influencing factors for detection rate of CsPCa. Conclusions:For patients with at least two PI-RADS score≥3 lesions on prostate magnetic resonance imaging, omitting SL can almost maintain the same detection efficacy.

Volume loss caused by aging process, diseases, trauma and surgical treatments, could lead to facial depressions, profoundly affecting appearance. Injectable fillers could help to correct this type of disfigurements and are preferred by plastic surgeons and patients due to their quality of minimal invasiveness and better delicateness. Among these fillers, collagen stimulators such as poly-L-lactic acid(PLLA) and polycaprolactone(PCL) are biodegradable synthetic polymers that can stimulate collagen formation and thus gradually restore tissue volume. These polymers have been used worldwide to treat facial aging changes and human immunodeficiency virus-associated facial fat lipoatrophy, demonstrating ideal results in volume enhancement and facial rejuvenation. The progress and clinical applications of compound injectables based on biodegradable collagen stimulators are summarized.

OBJECTIVE To systematically review the effects of body weight on the efficacy and safety of novel oral anticoagulants （NOACs） or aspirin for the prevention of venous thromboembolism （VTE） after total hip arthroplasty and total knee arthroplasty （hereinafter referred to as “hip and knee arthroplasty”）. METHODS Retrieved from PubMed， Embase and Cochrane library， randomized controlled trial （RCT） and non-RCT about the effectiveness and/or safety of NOACs， aspirin and low- molecular heparin by subgrouping according to body weight or body weight index [BMI 18.5-＜25 kg/m2 as normal body mass， BMI 25-30 kg/m2 as overweight， and BMI＞30 kg/m2 as obesity （of them， BMI＞40 kg/m2 as morbid obesity）] were collected from the inception to June 30， 2022. After literature screening and data extraction， the quality of RCT was evaluated with bias risk assessment tool RoB 2.0 recommended by Cochrane system evaluator manual. The Newcastle-Ottawa scale was used to evaluate the quality of non-RCT. Meta-analysis was performed by using RevMan 5.4 software. RESULTS A total of 6 literatures， containing 3 series of RCT pooled studies and 3 non-RCTs were included. The results of meta-analysis showed that among different BMI subgroups， there was no statistical significance in reducing major VTE and VTE-related mortality of patients with normal body mass patients [OR＝0.63， 95%CI（0.26，1.51），P＝0.30]， overweight patients [OR＝0.48，95%CI（0.22，1.04），P＝0.06] and obese patients [OR＝0.70，95%CI（0.40，1.25），P＝0.23] by NOACs， compared with enoxaparin. The safety of NOACs was comparable to that of enoxaparin in different BMI subgroups in terms of the incidence of major bleeding events and major+clinically relevant non- major bleeding events （P＞0.05）. There was no statistical significance in the incidences of total VTE [OR＝1.28， 95%CI （0.68，2.40）， P＝0.45]， symptomatic VTE and all-cause mortality [OR＝1.26， 95%CI （0.81，1.95）， P＝0.30] and major bleeding [OR＝0.79， 95%CI （0.58，1.08）， P＝0.14] in obese/morbidly obese patients using NOACs and aspirin， compared with normal/overweight patients. CONCLUSIONS The impact of body weight on the efficacy and safety of NOACs and aspirin for the prevention of VTE after hip and knee arthroplasty is not significant， and this study supports that overweight and obese patients receive NOACs or aspirin for VTE prevention.
