Acute lateral ankle sprain (ALAS) is one of the most common sport injuries, with high incidence, recurrence and disability rates. Currently, exercise rehabilitation-based non-surgical treatment is the primary management approach for ALAS. However, there remain improper practices such as excessive immobilization or uncontrolled activity, which contribute to recurrent sprains and chronic ankle instability, significantly impairing patients′ athletic function and quality of life. To standardize the non-surgical management of ALAS, improve the cure rates, and reduce the recurrence and disability rates, Chinese Sports Rehabilitation Medicine Training Project of Chinese Medical Association, Foot and Ankle Basics and Orthopedics Group, Orthopedic Branch of Chinese Medical Doctor Association, and Sports Medicine Branch of Jiangsu Medical Association organized relevant experts to formulate Expert consensus on non-surgical treatment for acute lateral ankle sprain ( version 2025), following the principles of scientific vigor, practicality, and innovation. Thirteen recommendations were proposed for standardized treatment protocols across different healing phases, aiming to provide references for standard management of ALAS and improve the therapeutic outcomes.

Objective:To construct an evaluation indicator system for the efficiency of nursing human resources in integrated medical and elderly care institutions using Data Envelopment Analysis (DEA) and subsequently evaluate its effectiveness.Methods:This cross-sectional survey utilized literature review and investigative methods to initially establish a library of evaluation indicators for nursing human resource efficiency. The Delphi method was employed in two rounds of consultations with 17 experts from various fields, including nursing management, elderly care institution management, integrated medical and elderly care institution management, health economics management, and public health. The reliability of the indicator system was assessed based on factors such as expert enthusiasm, authority, concentration of opinions, and coordination. Adjustments, modifications, and improvements were made to the indicators based on expert opinions to establish the final indicator system. From August to December 2022, the DEA model was applied to evaluate the efficiency of 12 integrated medical and elderly care institutions in Haikou city based on this indicator system.Results:The constructed evaluation indicator system comprised 68 items divided into three levels: 9 primary indicators, 19 secondary indicators, and 40 tertiary indicators. The positive coefficients of the two rounds of expert consultations were 100% and 94.1%, with authority coefficients of 0.88 and 0.92, Kendall harmony coefficients of 0.471 and 0.348, and mean coefficients of variation of 0.16 and 0.12 ( P<0.001). DEA evaluation results for the 12 integrated medical and elderly care institutions showed that 5 were DEA effective institutions with comprehensive efficiency (OE), technical efficiency (TE), and scale efficiency (SE) values all equal to 1.000, while 7 were non-DEA effective institutions, including 4 with SE <1.000 but TE=1.000 and 3 with both SE and TE<1.000. Conclusions:The constructed evaluation indicator system demonstrates high enthusiasm, authority coefficients, and coordination in expert consultations, indicating high acceptability and comprehensive content with distinct levels and strong specialty characteristics. The DEA model′s evaluation results objectively and effectively reflect the efficiency of nursing human resources in integrated medical and elderly care institutions, demonstrating practical utility.

Objective:To investigate the effect of intravenous application of furosemide on occurrence of cardiac surgery-associated acute kidney injury (CSA-AKI) in patients after cardiac surgery.Methods:The electronic medical records of patients undergoing cardiac surgery in Linyi People′s Hospital from January 2014 to December 2022 were collected and retrospectively analyzed. According to whether CSA-AKI occurred after surgery, the patients were divided into AKI group and non-AKI group and the clinical characteristics between the 2 groups were compared. Multivariate logistic regression was used to analyze the influencing factors of CSA-AKI, and the odds ratio ( OR) and its 95% confidence interval ( CI) were calculated. Results:A total of 2 633 patients were enrolled in the analysis, including 1 601 males (60.8%) and 1 032 females (39.2%). The age was (62.8±8.9) years, ranging from 18 to 85 years. Among the 2 633 patients, 491 (18.6%) developed CSA-AKI. Multivariate logistic regression analysis showed that after adjusting for factors such as the type of operation, intraoperative cardiopulmonary bypass, hypertension, diabetes mellitus, hypoalbuminemia, NYHA cardiac function class Ⅲ/Ⅳ, intraoperative/postoperative aortic balloon counterpulsation, preoperative serum creatinine level, operation duration, and the number of vasoactive drugs used after the operation, postoperative intravenous application of furosemide was still independently associated with the occurrence of CSA-AKI ( OR=2.161, 95 %CI: 1.720-2.715, P<0.001). Conclusions:The incidence of CSA-AKI in patients enrolled in this study was 18.6%. Intravenous use of furosemide after cardiac surgery can increase the risk of CSA-AKI.

OBJECTIVE: To explore the biomarkers of tinnitus in vestibular schwannoma patients using electroencephalographic (EEG) microstate technology. METHODS: The EEG and clinical data of 41 patients with vestibular schwannoma were collected. All the patients were evaluated by SAS, SDS, THI and VAS scales. The EEG acquisition time was 10-15 min, and the EEG data were preprocessed and analyzed using MATLAB and EEGLAB software package. RESULTS: Of the 41 patients with vestibular schwannoma, 29 patients had tinnitus and 12 did not have tinnitus, and their clinical parameters were comparable. The average global explanation variances of the non-tinnitus and tinnitus groups were 78.8% and 80.1%, respectively. The results of EEG microstate analysis showed that compared with those without tinnitus, the patients with tinnitus had an increased frequency (P=0.033) and contribution (P=0.028) of microstate C. Correlation analysis showed that THI scale scores of the patients were negatively correlated with the duration of microstate A (R=-0.435, P=0.018) and positively with the frequencies of microstate B (R=0.456, P=0.013) and microstate C (R=0.412, P=0.026). Syntax analysis showed that the probability of transition from microstate C to microstate B increased significantly in vestibular schwannoma patients with tinnitus (P=0.031). CONCLUSION EEG microstate features differ significantly between vestibular schwannoma patients with and without tinnitus. This abnormality in patients with tinnitus may reflect the potential abnormality in the allocation of neural resources and the transition of brain functional activity.

Objective:To investigate the effect of preoperative use of diuretics on cardiac surgery-associated acute kidney injury(CSA-AKI)in elderly patients.Methods:In this single-center retrospective study, 1 638 patients aged ≥60 years and undergone cardiac surgery(including coronary artery bypass grafting, valve replacement and valvuloplasty)in the Department of Cardiovascular Surgery, Linyi People's Hospital between January 2015 and December 2022 were recruited.The last preoperative serum creatinine(SCr)level was taken as the baseline value, and AKI was diagnosed according to the Kidney Disease Improving Global Outcomes(KDIGO)criteria.Patients were divided into an AKI group and a non-AKI group according to whether AKI occurred after surgery.The clinical characteristics of the two groups were compared, and the effect of preoperative use of diuretics on CSA-AKI was evaluated by multivariate Logistic regression analysis.Results:Of 1638 patients enrolled in the study, 284 patients(17.3%)developed CSA-AKI.Compared with the non-AKI group, there were higher proportions of patients in the AKI group receiving furosemide(62.7% or 178/284 vs.46.2% or 626/1 354, χ2=25.397, P<0.001), spironolactone(70.1% or 199/284 vs.49.9% or 676/1 354, χ2=38.284, P<0.001), and hydrochlorothiazide(8.1% or 23/284 vs.3.5% or 47/1354, χ2=12.288, P<0.001). The number of diuretics in the AKI group was higher than in the non-AKI group[2(0, 2) vs.1(0, 2), Z=-6.381, P<0.001], and the proportion of patients using ≥2 diuretics was higher in the AKI group than in the non-AKI group(70.1% or 199/284 vs.49.0% or 664/1354, χ2=41.652, P<0.001). Multivariate Logistic regression analysis showed that, after adjusting for hypertension, diabetes mellitus, hypoalbuminemia, NYHA functional class Ⅲ/Ⅳ, cardiopulmonary bypass during surgery, operative duration≥6 h, postoperative blood transfusion>600 ml, postoperative use of >3 vasoactive drugs and other variables, preoperative use of ≥2 diuretics remained an independent risk factor for CSA-AKI in elderly patients( OR=1.580, 95% CI: 1.042-2.396, P=0.031). Conclusions:AKI is a common complication after cardiac surgery in elderly patients.Preoperative use of ≥2 diuretics used may be an independent risk factor for CSA-AKI.

Objective:To evaluate the feasibility and efficacy of 68Ga-PSMA PET/CT-guided targeted prostate biopsy for the diagnosis of clinically significant prostate cancer(csPCa). Methods:This retrospective analysis allocated 89 patients with elevated PSA levels between 4.0-20.0 ng/ml to PET group(n=48) or TRUS group(n=41) between September 2017 and June 2019. Patients with PSMA-avid lesions (SUV max≥8.0) underwent PET-TB via a single-puncture percutaneous transgluteal approach (n=19), while patients with negative PSMA-PET underwent systematic TRUS-GB (n=29). Patients in the TRUS group who did not get 68Ga-PSMA PET/CT examination underwent TRUS-GB directly (n=41). The mean age, prostate volume, PSA value of PET group and TURS group were (71.2±9.1) years vs. (68.0±12.0) years, (62.9±29.1)ml vs. (65.4±38.9)ml , 8.8(6.6, 13.6) ng/ml vs. 9.8(7.1, 13.1)ng/ml, respectively (all P>0.05). The diagnostic efficacy and difference of PCa and csPCa between the two groups were compared. PET-TB adopts a new mode of percutaneous gluteus approach and carries out precise image fusion of PSMA-PET/CT and pelvic CT in the same machine and in the same position (prone position). Under the direct guidance of CT, the biopsy is performed with only one precise puncture. Results:PCa and csPCa were detected in 27/89(30.3%)and 20/89(22.5%)in all patients. PET group detected significantly more cases of PCa and csPCa than those of TRUS group [PCa: 41.7%(20/48) vs. 17.1%(7/41), χ2=6.328; csPCa: 33.3%(16/48) vs. 9.8%(4/41), χ2=7.055, P<0.01]. Of 19 patients with PSMA-PET positive, PET-TB detected 16 cases of PCa(84.2%) by a single needle puncture, and the proportions of cancer tissues were ≥80% in 2, 50%-79% in 8, and <50% in 6 cases. Among these, Gleason score was underestimated by biopsy histopathology in 2 patients. Of 3 patients with PET-TB negative, 1 case of low-risk PCa(Gleason 3+ 3) was detected by complementary TRUS-GB. The sensitivity, specificity, positive predictive value, negative predictive value, accuracy of 68Ga-PSMA PET/CT(SUV max≥8.0) for the diagnosis of csPCa were 73.9%(14/19), 93.1%(27/29), 87.5%(14/16), 81.3%(26/32)and 85.4%(41/48), respectively. For PET-TB, only one patient had slight symptoms of haematuria after the puncture, no cases of hematochezia, hemospermia, urinary retention or pelvic infection were observed. Conclusions:68Ga-PSMA PET/CT is a feasible novel puncture technique that may serve as a triage tool for prostate biopsy, and PET-TB may improve the detection rate of csPCa compared with TURS-GB, especially in patients with serum PSA 4.0-20.0 ng/ml.
