OBJECTIVE To investigate the incidence and outcomes of vancomycin-associated acute kidney injury (VA-AKI) in critically ill patients, to analyze the independent risk factors for the development of VA-AKI and renal function outcomes in VA-AKI patients, and to evaluate the predictive performance of vancomycin treatment duration for VA-AKI occurrence, so as to provide reference for the rational and safe use of this drug.METHODS Clinical data of critically ill patients who received vancomycin during hospitalization in the intensive care unit of Zhongshan Hospital, Fudan University,from January 2022 to December 2024 were retrospectively collected. Patients were divided into the VA‑AKI group and the non‑AKI group according to the occurrence of VA‑AKI. Multivariate Logistic regression analysis was performed to screen for independent risk factors for VA‑AKI development and renal function outcomes in patients with VA‑AKI. The receiver operating characteristic (ROC) curve was used to analyze the predictive performance of vancomycin treatment duration for VA‑AKI.RESULTS A total of 1 484 patients were enrolled, among whom 287 developed VA‑AKI, with an incidence of 19.3%. The overall median time to onset was 2.5 days after vancomycin administration. Complicated hypertension, cardiac or renal insufficiency, hospital‑acquired sepsis/bacteremia, multiple organ failure, invasive mechanical ventilation during hospitalization, vancomycin treatment duration ≥10 days, and concomitant use of carbapenems or tacrolimus were independent risk factors for VA‑AKI ( P <0.05). Concomitant use of vasopressors was an independent risk factor for renal function outcomes in patients with VA‑AKI ( P <0.05). The area under the ROC curve (AUC) of the model using vancomycin treatment duration of predict the occurrence of VA-AKI was 0.624. At the optimal cut‑off value of 9.7 days, the sensitivity and specificity were 47.4% and 74.9%, respectively.CONCLUSIONS Critically ill patients have a relatively high incidence of VA-AKI, which mostly occurs in the early stage of vancomycin therapy. Patients with underlying cardiac-renal diseases, severe infection, requirement for mechanical ventilation, prolonged vancomycin therapy, and concomitant administration of carbapenems or tacrolimus are at high risk for VA-AKI. Concomitant vasopressor use affects renal function recovery in patients with VA-AKI. The predicted risk of acute kidney injury is higher when vancomycin treatment duration is ≥10 days.

OBJECTIVE To compare the predictive accuracy and clinical applicability of four vancomycin individualized dosing tools (SmartDose, ClinCalc, Gulou, Pharmado) and provide a basis for rational clinical medication use. METHODS A retrospective cohort study was conducted, enrolling 479 adult patients who received vancomycin therapy and underwent steady-state trough concentration monitoring in Zhongshan Hospital, Fudan University (Xiamen Branch) from January 1, 2022, to June 30, 2024. The predictive accuracy of each tool was evaluated using indicators, such as mean error (ME), mean absolute error (MAE), mean percentage error (MPE), mean absolute percentage error (MAPE), the proportion of patients with an absolute percentage error (APE) of less than 30%, the 95% limits of agreement, and the overall relative percentage difference between predicted and measured values. Using indicators such as accessibility, patient management, and recommendation of multiple treatment options, the clinical panxso@163.com applicability of the tools for all patients was evaluated; using the discrepancy in accuracy between the predicted and actual measured blood drug concentrations as an indicator, the clinical applicability was assessed for patients in different renal function subgroups (hyperfunction, normal, mild impairment, moderate impairment, and severe impairment). RESULTS In terms of accuracy, SmartDose demonstrated the best overall performance with an MAPE of 46.40% and a proportion of APE <30% (46.56%). Bland-Altman analysis indicated that SmartDose had the smallest overall relative percentage difference (-7.25%), although the 95% limits of agreement were broad for all tools, with differences between the upper and lower limits exceeding 200%. In terms of applicability, all four dosing tools were freely accessible and demonstrated good availability; SmartDose and Pharmado provided the most comprehensive solutions, offering features such as patient management, multiple regimen recommendations, and drug concentration-time curve plotting. Stratified analysis based on renal function revealed that Pharmado showed optimal prediction for hyperfiltration patients (mean difference: 0.11 mg/L). SmartDose and ClinCalc showed relatively better performance in normal and mild renal impaiment (mean difference: 0.37, 0.51 mg/L and -1.13, -1.33 mg/L,respectively). SmartDose performed best in moderate renal impairment (mean difference: -2.60 mg/L). Pharmado and Gulou had smaller prediction biases in severe renal impairment (mean differences: 1.52 mg/L and -0.23 mg/L, respectively). CONCLUSIONS The four individualized dosing tools demonstrated limited accuracy in the initial prediction of vancomycin concentrations. Among them, SmartDose demonstrates the highest overall prediction accuracy and possesses comprehensive clinical management features. It is recommended that Pharmado be preferred for patients with renal hyperfiltration; SmartDose or ClinCalc can be used for patients with normal or mildly impaired renal function; SmartDose is recommended for patients with moderately impaired renal function; Pharmado or Gulou may be considered for patients with severely impaired renal function.

OBJECTIVE:
To investigate the impact of autophagy on cardiac tissue injury following common bile duct ligation (CBDL) in rats.
METHODS:
Twenty-four SPF grade healthy adult male Sprague-Dawley (SD) rats were randomly divided into four groups, with 6 rats in each group. The sham-operated (Sham) group underwent only dissection of the common bile duct without ligation. The CBDL group underwent CBDL to simulate jaundice-induced myocardial injury. The autophagy inhibitor 3-methyladenine (3-MA)+CBDL group was intraperitoneally injected with 15 mg/kg 3-MA 2 hours before modeling, and then injected once every other day. The CBDL+autophagy enhancer rapamycin (Rapa) group was intraperitoneally injected with Rapa 1 mg/kg 0.5 hour after modeling, and then injected once every other day. The rats in each group were sacrificed 2 weeks after surgery, and blood was taken from the inferior vena cava. Serum total bilirubin (TBil), alanine transaminase (ALT), aspartate transaminase (AST), lactate dehydrogenase (LDH), and MB isoenzyme of creatine kinase (CK-MB) were detected by using a fully automated animal biochemical analyzer. Serum oxidative stress marker superoxide dismutase (SOD) activity and malondialdehyde (MDA) content were detected by colorimetric assay. The heart tissues of rats were taken and pathological changes were observed under a light microscope after hematoxylin-eosin (HE) staining. Transmission electron microscope was used to observe autophagosomes after double staining with uranyl acetate and lead citrate. The expressions of autophagy-related proteins were detected using Western blotting.
RESULTS:
Compared with the Sham group, the serum SOD activity of rats in the CBDL group was significantly decreased, while the serum MDA, TBil, ALT, AST, LDH, and CK-MB were significantly increased; the expressions of autophagy-related proteins Beclin-1 and microtubule-associated protein 1 light chain 3-II/I (LC3-II/I) were significantly increased, and p62 protein expression was significantly decreased. Autophagosomes were seen under electron microscopy in the CBDL group, and cardiac histopathological morphology showed focal necrosis in the myocardium as well as infiltration of inflammatory cells, dilatation of small interstitial blood vessels, and myocardial fiber degeneration. Compared with the CBDL group, cardiac tissue injury in rats was attenuated by pretreatment with the autophagy inhibitor 3-MA, with a decrease in inflammatory cell infiltration in myocardial tissue, a reduction in interstitial vasodilatation, and a decrease in the area of myocardial fibrosis; a decrease in the number of autophagosomes by electron microscopy; and a further rise in the viability of serum TBil, ALT, and AST [TBil (μmol/L): 184.40±6.74 vs. 120.70±16.93, ALT (U/L): 501.10±62.18 vs. 178.80±22.30, AST (U/L): 806.50±76.92 vs. 275.50±55.81, all P < 0.01], as well as a decrease in the levels of serum SOD, MDA, LDH, and CK-MB [SOD (kU/L): 85.00±5.29 vs. 107.50±7.86, MDA (μmol/L): 10.72±0.93 vs. 15.06±1.88, LDH (U/L): 387.40±119.50 vs. 831.30±84.35, CK-MB (U/L): 320.10±14.04 vs. 814.70±75.66, all P < 0.05]. The expressions of the autophagy-related proteins Beclin-1 and LC3-II/I in cardiac tissues were significantly decreased [Beclin-1 protein (Beclin-1/GAPDH): 0.67±0.04 vs. 0.89±0.01, LC3-II/I ratio: 0.93±0.03 vs. 1.09±0.01, both P < 0.01], and p62 protein expression was significantly increased (p62/GAPDH: 0.99±0.01 vs. 0.60±0.01, P < 0.01). In contrast, compared with the CBDL group, after administration of the autophagy enhancer Rapa, the rats showed increased cardiac tissue injury, increased inflammatory cell infiltration in myocardial tissues, increased interstitial vasodilatation, and increased area of myocardial fibrosis; an increase in autophagosomes was seen by electron microscopy; the change tendency of serum biochemical indicators and proteins in myocardial tissues were opposite with autophagy inhibition group with a decrease in serum TBil, ALT, and AST [TBil (μmol/L): 22.00±3.21 vs. 120.70±16.93, ALT (U/L): 72.13±5.97 vs. 178.80±22.30, AST (U/L): 135.20±12.95 vs. 275.50±55.81, all P < 0.05], as well as a increase in the levels of serum SOD, MDA, LDH, and CK-MB [SOD (kU/L): 208.00±2.65 vs. 107.50±7.86, MDA (μmol/L): 20.38±0.40 vs. 15.06±1.88, LDH (U/L): 1 268.00±210.90 vs. 831.30±84.35, CK-MB (U/L): 1 150.00±158.70 vs. 814.70±75.66, all P < 0.05]. The protein expressions of Beclin-1 and LC3-II/I in cardiac tissues were significantly increased [Beclin-1 protein (Beclin-1/GAPDH): 0.96±0.01 vs. 0.89±0.01, LC3-II/I ratio: 1.19±0.01 vs. 1.09±0.01, both P < 0.05], and p62 protein expression was significantly decreased (p62/GAPDH: 0.19±0.02 vs. 0.60±0.01, P < 0.01).
CONCLUSIONS
Activation of autophagy in CBDL rats led to myocardial tissue injury and reduced cardiac function. Inhibition of autophagy improved cardiac tissue injury in CBDL rats, while increasing autophagy exacerbated myocardial tissue injury.

Objective:To investigate the mediating effect of psychological flexibility between recurrence risk perception and health behavior in stroke patients.Methods:From July to December 2024, 233 stroke patients at the First Affiliated Hospital of Zhengzhou University were selected using convenience sampling. Electronic questionnaires were used to collect patients' general information, perception of stroke recurrence risk, health behavior, and psychological flexibility.Results:The scores for recurrence risk perception, psychological flexibility, and health behavior of 233 stroke patients were (39.75±4.39), (47.45±4.19), and (54.04±3.78), respectively. Health behavior were positively correlated with recurrence risk perception ( r=0.495, P<0.01), and negatively correlated with psychological flexibility ( r=-0.367, P<0.01). Psychological flexibility partially mediated the relationship between recurrence risk perception and health behavior, with an effect value of 0.080 and an effect proportion of 17.5% (0.080/0.458) . Conclusions:Recurrence risk perception not only directly predicts health behavior in stroke patients but also indirectly influences their health behavior through psychological flexibility. Healthcare providers should enhance recurrence risk perception among stroke patients and incorporate the improvement of psychological flexibility as part of intervention strategies to improve patients' health behavior.

Objective:To explore the association between spicy food intake and the risk for cardio/cerebrovascular diseases.Methods:Data were collected from the China Kadoorie Biobank project conducted in Pengzhou, Sichuan Province. Using the Cox proportional hazards regression model, we analyzed the associations of the frequency of spicy food intake, spicy level, types of spicy food, and the age when regular intake of spicy food began (intake in 1 day/week), with the risk for cardio/cerebrovascular disease. Furthermore, the associations with the risks for ischemic heart disease (IHD) and cerebrovascular diseases, as well as the risk of ischemic stroke (IS) and hemorrhagic stroke (HS) were analyzed.Results:A total of 54 859 study participants were included in the study, in whom 49 320 had spicy food intake (89.90%). In these participants, 37 680 (68.69%) had spicy food intake in 6-7 days/week, 5 036 (9.18%) had spicy food intake in 1-5 days/week, and 6 604 (12.03%) had spicy food intake once a week; 5 539 (10.10%) had never/almost never had spicy food intake. After adjusting for multiple confounding factors, compared with those who never/almost never had spicy food intake, intake of spicy food was associated with reduced risks for IHD (intake in 6-7 days/week: HR=0.86, 95% CI: 0.78-0.95), cerebrovascular diseases (intake in 6-7 days/week: HR=0.88, 95% CI: 0.81-0.96), and IS (intak in 6-7 days/week: HR=0.85, 95% CI: 0.76-0.95). With the increase of spicy food intake frequency, the risk for cardio/cerebrovascular disease decreased (intake in 1-5 days/week: HR=0.91, 95% CI: 0.85-0.98; intake in 6-7 days/week: HR=0.89, 95% CI: 0.84-0.94) (trend test P<0.001). However, no statistical association was found between spicy food intake and the risk for HS. In terms of spicy level, after adjusting for multiple confounding factors, compared with those who never/almost never had spicy food intake, intake of spicy food was associated with reduced risk for cardio/cerebrovascular disease (moderate: HR=0.86, 95% CI: 0.82-0.90) and cerebrovascular disease (moderate: HR=0.90, 95% CI: 0.84-0.97). With the increase of spicy level, the risk for IHD decreased (moderate: HR=0.86, 95% CI: 0.79-0.93; strong: HR=0.84, 95% CI: 0.74-0.95) (trend test P<0.001). After adjusting for multiple confounding factors, compared with those who never/almost never had spicy food intake, intake of any type of spicy food was associated with reduced risk for cardio/cerebrovascular disease, IHD, and cerebrovascular disease. Regulat intake of spicy food from age 0-10 years was associated with reduced risk for cardio/cerebrovascular disease, IHD, and cerebrovascular disease. Regular intake of spicy food from age 11-20 years reduced the risk for cardio/cerebrovascular disease and IHD. There was no significant association between the regular intake of spicy food from age 21-79 years and the risks for cardio/cerebrovascular disease, IHD and cerebrovascular disease. Conclusion:The intake of spicy food could reduced the risk for cardio/cerebrovascular diseases, IHD, cerebrovascular diseases and IS in residents aged 30-79 years in Sichuan.

Objective:To investigate the effect of physical activity on mortality risk in patients with chronic obstructive pulmonary disease (COPD) in Sichuan Province.Methods:Based on baseline data from 2004 to 2008 from the China Kadoorie Biobank project site in Pengzhou City, Sichuan Province, a total of 8 501 COPD patients aged 30-79 years were enrolled and followed up for a long period to determine mortality outcomes. Quartiles were used to group physical activity levels. The Cox proportional hazards regression model was used to analyze the effect of physical activity level on mortality outcomes.Results:As of December 31, 2017, the cumulative follow-up of the participants totaled 85 600.58 person-years (mean follow-up duration: 10.07 years). During this period, a total of 2 000 deaths were recorded, yielding a cumulative mortality rate of 23.53%. Among these deaths, 665 were attributed to COPD, corresponding to a cumulative mortality rate of 7.82%; and 1 116 were attributed to cardiovascular and cerebrovascular disease (CVD), corresponding to a cumulative mortality rate of 13.13%. The Cox proportional hazards regression model analysis revealed that, after adjusting for confounding factors, total physical activity was associated with a reduced risk of mortality from COPD, CVD, and all causes in patients with COPD. Compared with the low-level group of total physical activity, the medium-high-level group had the lowest risk of COPD mortality, with an HR of 0.39 (95% CI: 0.30-0.49). The high-level group had the lowest risk of CVD death and all-cause death, with HRs of 0.46 (95% CI: 0.37-0.56) and 0.55 (95% CI: 0.48-0.64), respectively. The lowest risk of COPD death and CVD death was found in the medium-high level of work-based physical activity group, with HRs of 0.36 (95% CI: 0.28-0.46) and 0.43 (95% CI: 0.36-0.51), respectively; the risk of all-cause mortality was lowest in the medium-high and high-level groups, with HRs values of 0.53 (95% CI: 0.46-0.61) and 0.53 (95% CI: 0.45-0.61). The risk of COPD death was lowest in the high-level transportation physical activity group, with an HR of 0.66 (95% CI: 0.53-0.83), and the risk of CVD and all-cause death was lowest in the medium-high level group, with HRs of 0.63 (95% CI: 0.53-0.76) and 0.73 (95% CI: 0.64-0.84), respectively. The risk of COPD death and CVD death was the lowest in the high-level domestic physical activity group, with HRs of 0.66 (95% CI: 0.49-0.89) and 0.76 (95% CI: 0.61-0.95), respectively, and the risk of all-cause death was the lowest in the medium-high level group, with an HR of 0.82 (95% CI: 0.72-0.94). There is no statistical association between leisure physical activity and the risk of death from three types of diseases. Conclusions:Total physical activity, including work-based, transportation-based, and domestic physical activity, reduced the risk of COPD, CVD, and all-cause mortality in patients with COPD in Sichuan Province. The magnitude of mortality risk was influenced by the type and level of physical activity.

The aim of this updated guideline is to provide comprehensive recommendations for the management of gout in patients with common comorbidities, such as chronic kidney disease(CKD), cardiovascular disease(CVD), diabetes, osteoarthritis(OA), and gastrointestinal disorders. This guideline was developed by a multidisciplinary expert panel consisting of specialists in endocrinology, rheumatology, nephrology, cardiology, gastroenterology, and methodology. The development process adhered to standard methodologies, including PICO(population, intervention, comparator, and outcomes) question deconstruction, systematic literature review, the Grading of Recommendations Assessment, Development and Evaluation(GRADE) for evidence and recommendation evaluation, Delphi voting, and expert consensus. The guideline presents 26 evidence-based recommendations addressing 7 clinical questions for patients with hyperuricemia and gout in the context of comorbidities. Key recommendations include the maintenance of strict serum urate targets, particularly for patients with CKD stage≥3, chronic gouty arthritis, and OA, in order to prevent disease progression. In patients with CVD or diabetes, intra-articular triamcinolone is preferred over systemic glucocorticoids. Prioritized anti-inflammatory treatments for patients with CKD, gastrointestinal diseases and OA are recommended. The guideline also introduces emerging therapies, such as interleukin-1 inhibitors and selective urate transport inhibitors, as potential treatment options for refractory cases. The update offers a comprehensive, patient-centered approach to managing gout, particularly in individuals with associated comorbidities. Multidisciplinary collaboration and emerging new treatments and evidence ensure the optimization of the recommendations.
