Creutzfeldt-Jakob disease(CJD)is a rapidly progressive and fatal neurodegenerative disorder caused by prions,with certain infectivity and iatrogenic transmission risks.With the rapid progress and application of new dia-gnostic biomarkers and detection methods,as well as the construction and improvement of surveillance and reporting systems,the detection of CJD in patients domestically and internationally has shown an increasing trend year by year.Due to its long incubation period and heterogeneity of early symptoms,early identification and diagnosis of the disease is difficult,increasing the risk of transmission within medical institutions.Currently,there is a lack of con-sensus on the infection prevention and control of CJD.In order to timely identify and diagnose CJD as well as effec-tively block its transmission in medical institutions,this consensus summarizes 15 clinical concerns and formulates 24 specific recommendations based on the latest domestic and international research findings and clinical evidence,as well as combines with clinical practice,aiming to standardize healthcare-associated infection prevention and control measures for CJD and reduce its transmission risk in medical institutions.

Cardiovascular diseases(CVD)are chronic disease with high morbidity and mortality in the world.Pinellia ternatais a traditional Chi-nese medicinal herb and has the effects on drying dampness,resolving phlegm,lowering symptoms,stopping vomiting and relieving swelling.In recent years,researches showed that Pinellia ternataand its active ingredients(β-sitosterol,baicalin,baica-lein,quercetin)had significant effects in the treat-ment of cardiovascular diseases.This review sum-marized and analyzed the role and mechanism of Pinellia ternata and its active ingredients in cardio-vascular diseases,which provided a theoretical ba-sis for its clinical application.

Objective:To investigate the life expectancy of antiretroviral treatment (ART) HIV-infected patients and its trends in Taizhou City, Zhejiang Province from 2014 to 2023.Methods:The data were obtained from the China Information System for Disease Control and Prevention , and the study subjects were HIV-infected patients received ART in Taizhou City. An abbreviated life expectancy table was prepared based on Chiang's method to analyze the differences in life expectancy of HIV-infected patients receiving ART in Taizhou City with different characteristics in 2023 and to compare the trends in life expectancy of patients with different CD4 +T lymphocytes (CD4) counts at the time of initiation of ART from 2014 to 2023. Results:A total of 4 825 patients were enrolled in this study, with a cumulative follow-up of 276 648.56 person-years, and a case-fatality rate of 18.07 (95% CI: 16.48-19.65) /1 000 person-years. In 2023, male patients had lower life expectancy than females in all age groups, and those who were married had higher life expectancy than those who were unmarried and those who were divorced or widowed; patients who had been transmitted heterosexually had lower life expectancy than those who had been transmitted through homosexual transmission. Patients with different CD4 counts at the time of initiating ART had different life expectancies in all age groups. The life expectancy of patients with CD4 counts ≥350 cells/μl when initiating the treatment was higher than that of patients with CD4 counts <200 cells/μl in all age groups. The life expectancy of HIV-infected patients on ART at age 20 and 50 increased from 39.0 years and 19.1 years in 2014 to 46.0 years and 24.1 years in 2023, respectively, with an average annual percentage change of 2.43% (95% CI: 0.81%-4.07%) and 3.34% (95% CI: 1.17%-5.56%). The change in life expectancy was similar for patients with CD4 counts ≥350 cells/μl and 200-349 cells/μl at the time of initiating treatment in 2016-2023, and was higher than that for patients with CD4 counts <200 cells/μl. The rate of increase in life expectancy for patients at age 50 was higher than that at age 20 for all CD4 counts. Conclusions:The rising trend of life expectancy among HIV-infected patients on ART in Taizhou City is obvious. But the disparity between patients with different characteristics is obvious, especially among patients with baseline CD4 counts <200 cells/μl, suggesting the importance of expanded testing, early diagnosis and timely initiation of ART to improve the life expectancy of HIV-infected patients.

Objective:To investigate the relationship between the severity of pharyngolaryngeal sensory impairment and swallowing biomechanics as well as the risk of penetration-aspiration in patients with dysphagia following infratentorial stroke.Methods:This retrospective cross-sectional study enrolled 51 patients with dysphagia following infratentorial stroke hospitalized in the Department of Rehabilitation Medicine of The Third Affiliated Hospital of Sun Yat-sen University between January 2022 and December 2023. Participants were categorized into three groups: normal sensation group [15 males, 2 females; age range 29-76 (56.0±13.3)years], diminished sensation group[16 males, 3 females; age range 38-80(62.0±11.8)years], and absent sensation group [14 males, 1 female; age range 44-75 (60.0±9.7)years]. All patients underwent laryngoscopy and videofluoroscopic swallowing study, which included pharyngolaryngeal sensory testing and Penetration-Aspiration Scale assessment. Swallowing temporal parameters were quantitatively analyzed. Group comparisons for different variable types were conducted using the Chi-square test, one-way ANOVA, and the Kruskal-Wallis test. The correlation between sensory groups and Penetration-Aspiration Scale scores was assessed using Spearman′s correlation analysis. Logistic regression was employed to analyze the impact of pharyngolaryngeal sensory function on penetration-aspiration events.Results:Among the 51 patients, 33.33% (17/51) had normal pharyngolaryngeal sensation, while, 66.67% (34/51) exhibited sensory impairment. The normal sensation group exhibited a significantly longer laryngeal vestibule closure (LVC) time [792 (643, 1 205) ms] compared to the diminished [528 (380, 776) ms] and absent sensation groups [380 (322, 404) ms] ( H=6.502, P=0.039). Additionally, the upper esophageal sphincter opening time was longer in the normal sensation group than in the absent sensation group [528 (371, 710) ms vs 182 (0, 710) ms, H=6.003, P=0.049]. Correlation analysis indicated a significant negative correlation between the severity of sensory impairment and Penetration-Aspiration Scale scores ( r=-0.366, P=0.008). Logistic regression analysis demonstrated that greater sensory impairment was an independent risk factor for penetration-aspiration ( OR=9.29, 95%CI=1.57-54.77, P=0.014). Conclusion:Pharyngolaryngeal sensory deficits are common after infratentorial stroke dysphagia and are significantly associated with impaired swallowing biomechanics and increased aspiration risk. The severity of sensory deficit is a key determinant of penetration-aspiration risk, highlighting its value in risk stratification and therapeutic decision-making for dysphagia.

To summarize the nursing experience of a patient with T-cell precursor acute lymphoblastic leukemia complicated with excessive dynamic airway collapse.Key nursing points include:efficient treatment of airway collapse to avoid causes of airway hyper responsiveness;avoiding the blockage of phlegm suppository,ensuring a safe and smooth airway;preventing the risks of hemorrhage and thrombosis,and strictly implement hospital infection prevention and control measures.After active rescue and careful nursing care,the patient was transferred back to the general thoracic surgery ward 13 days later,improved 17 days later,and was admitted to the cancer hospital for continued treatment.

Objective: To explore the mediating effects of activities of daily living (ADL) and social participation on depressive symptoms and cognitive function among the elderly, so as to provide the basis for preventing cognitive decline. Methods: Basic information, depressive symptoms, cognitive function, ADL, and social participation of the elderly aged 60 and above were collected through the 2020 database of China Health and Retirement Longitudinal Study. The Process 4.3 program was used to analyze the mediating effects of ADL and social participation on depressive symptoms and cognitive function among the elderly. Results: A total of 6 722 elderly people were enrolled, including 3 791 males (56.40%) and 2 931 females (43.60%). The mean age was (68.52±6.00) years. The median depressive symptoms score was 7.00 (interquartile range, 9.00) points, with 2 436 individuals (36.24%) having depressive symptoms. The median cognitive function score was 12.50 (interquartile range, 4.50) points. The median ADL score was 0 (interquartile range, 1.00) point, with 2 173 individuals (32.33%) having ADL impairment. The median social participation score was 1.00 (interquartile range, 1.00) point. Mediating effect analysis showed that, after controlling for variables such as age, educational level, and residence, depressive symptoms indirectly negatively affected cognitive function through the independent mediating effects of ADL (β=-0.031, 95%CI: -0.042 to -0.020) and social participation (β=-0.008, 95%CI: -0.011 to -0.004), and negatively affected cognitive function via the chain mediating effects of ADL and social participation (β=-0.002, 95%CI: -0.003 to -0.001). The total mediating effect accounted for 25.79% of the total effect. Conclusion Depressive symptoms may indirectly and negatively affect the cognitive function among the elderly through ADL and social participation.
