ObjectiveTo develop a community-family management model for older adults with mild cognitive impairment (MCI) and to formulate detailed application specifications, and to fully leverage the initiative of communities and families under limited resource conditions, for achieving community-based early detection and early intervention for older adults with MCI. MethodsA systematic literature review was conducted to identify pertinent publications. Corpus-based research methodologies were employed to extract, refine, integrate and synthesize management elements, thereby establishing the specific content and service processes for each stage of the management model. Utilizing the 5W2H analytical framework, essential elements such as management stakeholders, target populations, content and methods for each stage were delineated. The model and its application guidelines were finalized through expert consultation and demonstration. ResultsAn expert evaluation of the management model yielded mean scores of 4.84, 4.32 and 4.84 for acceptability, feasibility and systematicity, respectively. By integrating the identified core elements with expert ratings and feedback, the final iteration of the community-family management model for older adults with MCI was formulated. This model comprised of five stages: screening and identification, comprehensive assessment, intervention planning, monitoring and referral pathways to ensure implementation, and enhanced support for communities, family members and caregivers. Additionally, it included 18 specific application guidelines. ConclusionThe proposed management model may theoretically help delay cognitive decline, improve cognitive function and potentially promote reversal from MCI to normal cognition. It may also enhance the awareness and coping capacity of older adults and their families, strengthen community healthcare professionals' ability to early identify and manage MCI.

AIM:To evaluate the clinical efficacy of lamellar keratectomy and corneal collagen crosslinking(LKCCC)in treating superficial fungal keratitis.METHODS: Retrospective analysis. Totally 79 patients(79 eyes)with superficial fungal keratitis who underwent LKCCC in our hospital from January 2014 to October 2023 were included. After admission, routine antifungal drug treatment for 7 d showed no obvious improvement or progressive aggravation. The maximum diameter of corneal lesions in all patients was ≤7 mm, the maximum depth was no more than 50% of the corneal thickness at the location, and the remaining healthy corneal thickness was ≥300 μm. The follow-up time was 90 to 112 d.RESULTS:Among the included 79 eyes, the lesions were located in the central region of the cornea in 6 eyes, in the paracentral region in 61 eyes, and in the peripheral region in 12 eyes. Hypopyon was observed in 5 cases. LKCCC was successfully administered in 79 eyes, cured in 76 eyes(96%), and failed in 3 eyes(4%). The healing time of corneal epithelium in 76 cured eyes was 3-15 d, of which 51 eyes(67%)healed within 7 d and 24 eyes(32%)healed within 3 d. The uncorrected visual acuity(UCVA)and best corrected visual acuity(BCVA)of 76 eyes of cured patients were statistically significant compared with those preoperatively(P<0.0167). Two of the 3 failed eyes were located at the edge of the lesion and recovered after re-keratectomy. One eye was located in the center of the lesion and recovered after being covered by bulbar conjunctival flap. At the last follow-up, no other complications were observed in all patients except superficial cloud and thinning of cornea.CONCLUSION:LKCCC is a rapid and effective treatment for superficial fungal keratitis and can be considered a new treatment option.

AIM: To analyze the clinical utility and value of the ultra-wide-field swept-source optical coherence tomography angiography(UWF-SS-OCTA)technique in changes of blood flow density and thickness in the central and peripheral regions of the retina and choroid in patients with nonproliferative diabetic retinopathy(NPDR)with or without diabetic kidney disease(DKD).METHODS: Cross-sectional study. Totally 50 cases(50 eyes)of diabetes mellitus(DM)that visited our hospital between June 2023 and June 2024 were included. They were divided into three groups: NPDR combined with DKD group(DKD group, n=20), NPDR without DKD group(NDKD group, n=20), and DM without retinopathy group(DM group, n=10, which served as control). In order to investigate the impact of DKD on ocular microangiopathy in NPDR patients, the retina and choroid within 24 mm×20 mm of the scan were separated into central and peripheral areas using the 3×3 nine-grid partition option that comes with UWF-SS-OCTA, and the parameters were then quantitatively assessed.RESULTS:The central and peripheral blood flow density of the choroidal capillary layer(CCP)was statistically significant between the DM group and the DKD group(t=3.93, P=0.0003; t=3.34, P=0.0016), and between the NDKD group and the DKD group(t=-3.06, P=0.003; t=-2.55, P=0.013), but there was no statistically significant difference between the DM group and the NDKD group(t=1.44, P=0.157; t=1.26, P=0.21). The mid-large choroidal vessel(MLCV)showed a progressive decline in central and peripheral blood flow density in the DM, NDKD, and DKD groups(F=13.74, 19.03, all P<0.0001). The DM, NDKD, and DKD groups saw a progressive decrease in central and peripheral choroidal thickness(CT; F=10.72, P=0.0001; F=13.12, P<0.001).CONCLUSION:CCP, MLCV, and CT can be used as visual indicators to identify impaired renal function in patients with NPDR. UWF-SS-OCTA can support the development of precise and noninvasive monitoring and treatment technology for diabetic ocular microangiopathy, while also offering a scientific foundation for the joint management of DR and DKD.

With the rapid development of network technology， live surgery has become the new way of surgery teaching. However， the issue of patient privacy protection caused by live surgery has received widespread attention. Based on the evolutionary game theory， this paper constructed an evolutionary game model from the three-party perspectives of doctors， patients， and government and analyzed the game behaviors of the three parties in the process of live surgery. Matlab software was utilized to conduct dynamic simulation and numerical simulation analysis. It was found that the factors affecting the choice of doctors’ strategies included protection costs， the cost of privacy leakage， the benefits of protection， high-traffic benefits， and other aspects； the factors affecting the choice of patient strategies encompassed surgical costs， the risk of privacy leakage， additional benefits， and other aspects； the factors affecting the choice of government strategies embodied regulatory costs and the improvement of credibility. To realize a win-win situation among doctors， patients， and the government， the three parties need to work together to ensure that patient privacy is not violated and find a balance between expanding the influence of medical education and protecting patient privacy.

Objective To explore the relationship between education level and the risk of all-cause mortality in the middle-aged and elderly (≥45 years old) population in China. Methods Using data from five surveys from 2011-2020, years of education, age, gender, marital status, type of household, alcohol consumption status, smoking status, physical activity, limited ability to perform activities of daily living (ADLs), chronic disease status, and body mass index were collected. According to the survival status，the study participants were divided into a survival group (n=8625) and an all-cause mortality group (n=1735). Cox proportional risk regression model was used to analyze the relationship between years of education and the risk of all-cause mortality in middle-aged and elderly people with stratified analysis. Results The survey was conducted on 10360 research subjects, including 4 983 males and 5 377 females, with an age M(Q_R) of 59(8) years old. A total of 88 187 person years (average 8.512 person years) were followed up, and a total of 1735 deaths were reported over 9 years. The all-cause mortality rate was 19.674 ‰, with an education period M(Q_R) of 5(8) years and a survival time M(Q_R) of 9 (0) years. After adjusting for confounding factors, for every 1 year increase in education, the risk of all-cause mortality decreased by 2.60% [HR=0.974, 95% CI (0.960-0.988)]. The stratified analysis results showed that in the population aged 45-59, for every 1 year increase in education, the risk of all-cause mortality decreased by 1.00% [HR=0.990, 95% CI (0.959,1.021)]; In the population aged 60-74 and over 75, for every 1 year increase in education, the risk of all-cause mortality decreased by 2.70% [HR=0.973, 95% CI (0.948, 0.999)] and 3.50% [HR=0.965, 95% CI (0.929, 1.003)], respectively. Conclusion Improving the education level of middle-aged and elderly people (≥ 45 years old) in China can reduce the risk of all-cause mortality, and elderly education should be vigorously promoted.

The clinical data and genetic test results of a 7-year-old female child with cerebral cavernoma were retrospectively analyzed. The child was admitted to the hospital due to a one-month headache. Brain MRI showed cerebral cavernoma. The genetic testing showed a pathogenic heterozygous mutation c.456T＞G (p.Tyr152Ter, 61) in the programmed cell death 10 (PDCD10) gene, while both parents had the wild-type at the locus. The child had no symptoms of epileptic seizures, cerebral hemorrhage, or neurological dysfunction, and received conservative treatment, with regular outpatient follow-up MRI scans.

ObjectiveTo understand the current situation of medical damage liability disputes involving breach of the duty to inform in China， analyze the factors influencing the types of medical staff’s breach of the duty to inform， and explore the notification problems of medical staff in clinical practice. On these foundations， suggestions were proposed to improve the performance of the duty to inform and reduce medical disputes. MethodsUsing public cases from the China Judgements Online as the data source， the relationship between risk points and types of breach of duty to inform was analyzed using the Chi-square test. Logistic regression analysis was performed to explore the influencing factors of the types of breach of the duty to inform， and qualitative research summarized the specific contents of breach of the duty to inform. ResultsThere were differences in the effects of factors， including whether the patient was hospitalized， whether surgery was performed， whether Intensive Care Unit （ICU） treatment was required， the level of the medical institution， and whether a consultation occurred， on the types of breach of the duty to inform （P<0.05）. Whether surgery was performed was an influencing factor for the types of breach of the duty to inform. Qualitative research showed that the contents of breach of duty to inform primarily involve risk， treatment plan， and deficiencies in disease notification. ConclusionStrengthening the performance of the medical staff’s duty to inform should mainly focus on the medical side， coordinating with multiple parties and taking measures to improve the performance of the duty to inform， to reduce unnecessary medical disputes.

BACKGROUND: The effect of the interval between previous Helicobacter pylori (H. pylori) eradication and rescue treatment on therapeutic outcomes remains unknown. The aim of this study was to investigate the association between eradication rates and treatment interval durations in H. pylori infections. METHODS: This prospective observational study was conducted from December 2021 to February 2023 at six tertiary hospitals in Shandong, China. We recruited patients who were positive for H. pylori infection and required rescue treatment. Demographic information, previous times of eradication therapy, last eradication therapy date, and history of antibiotic use data were collected. The patients were divided into four groups based on the rescue treatment interval length: Group A, ≥4 weeks and ≤3 months; Group B, >3 and ≤6 months; Group C, >6 and ≤12 months; and Group D, >12 months. The primary outcome was the eradication rate of H. pylori . Drug compliance and adverse events (AEs) were also assessed. Pearson's χ2 test or Fisher's exact test was used to compare eradication rates between groups. RESULTS: A total of 670 patients were enrolled in this study. The intention-to-treat (ITT) eradication rates were 88.3% (158/179) in Group A, 89.6% (120/134) in Group B, 89.1% (123/138) in Group C, and 87.7% (192/219) in Group D. The per-protocol (PP) eradication rates were 92.9% (156/168) in Group A, 94.5% (120/127) in Group B, 94.5% (121/128) in Group C, and 93.6% (190/203) in Group D. There was no statistically significant difference in the eradication rates between groups in either the ITT ( P = 0.949) or PP analysis ( P = 0.921). No significant differences were observed in the incidence of AEs ( P = 0.934) or drug compliance ( P = 0.849) between groups. CONCLUSION: The interval duration of rescue treatment had no significant effect on H. pylori eradication rates or the incidence of AEs. REGISTRATION ClinicalTrials.gov , NCT05173493.

PROPOSE: To investigate the molecular mechanisms underlying the protective effects of ischemic preconditioning (IPC) in patients undergoing total knee arthroplasty. METHODS: GSE21164 was extracted from an online database, followed by an investigation of differentially expressed genes (DEGs) between IPC treatment samples at 2 time points (T0T and T1T). Function and pathway enrichment analyses were performed on the DEGs. A protein-protein interaction network was constructed to identify hub genes according to 5 different algorithms, followed by enrichment analysis. In addition, long noncoding RNAs (lncRNAs) were identified between the T0T and T1T samples. Furthermore, a competing endogenous RNA network was predicted based on the identified lncRNA-messenger RNA (mRNA), lncRNA-microRNA (miRNA), and mRNA-miRNA relationships revealed in this study. Finally, a drug-gene network was investigated. Statistical analyses were performed using GraphPad Prism 8.0. Differences between groups were determined using an unpaired t-test. p < 0.05 was considered significant. RESULTS: A total of 343 DEGs at T0 and 10 DEGs at T1 were identified and compared with their respective control groups, followed by 100 DEGs between T0T and T1T. Based on these 100 DEGs, protein-protein interaction network analysis revealed 9 hub genes, mainly with mitochondria-related functions and the carbon metabolism pathway. Six differentially expressed lncRNAs were investigated between T0T and T1T. A competing endogenous RNA network was constructed using 259 lncRNA-miRNA-mRNA interactions, including alpha-2-macroglobulin antisense RNA 1-miR-7161-5p-iron-sulfur cluster scaffold. Finally, 13 chemical drugs associated with the hub genes were explored. CONCLUSION Iron-sulfur cluster scaffold may promote IPC-induced ischemic tolerance mediated by alpha-2-macroglobulin antisense RNA 1-miR-7161-5p axis. Moreover, IPC may induce a protective response after total knee arthroplasty via mitochondria-related functions and the carbon metabolism pathway, which should be further validated in the near future.
