OBJECTIVES: This cross-sectional study aims to explore the association between oral health status and cognitive function in Chinese elderly individuals. METHODS: The survey participants were composed of elderly people aged≥60 who were admitted to West China Hospital of Stomatology, Sichuan University from August 2022 to March 2024. They were divided into a cognitive impairment (CI) group and a healthy control (HC) group according to the Montreal Cognitive Assessment (MoCA) score. General information and oral health indicators of all elderly people were collected. Independent sample t-test and chi-square test were used for inter-group comparison, and multiple linear regression model was applied for multivariate analysis of MoCA scores. RESULTS: A total of 402 elderly people were included in the study, and the number of remaining teeth in the CI group was significantly lower than that in the HC group. The decayed, missing, filled teeth index, debris index-simplified, gingival index, probing depth (PD), and clinical attachment loss in the CI group were all significantly higher than those in the HC group. There was no difference in denture wearing between the two groups. The results of multiple linear regression showed that there was a correlation between the number of remaining teeth and PD and MoCA scores after correcting for confounding factors. CONCLUSIONS Elderly individuals with CI have more prominent oral health issues compared to those with normal cognitive function. There may be a bidirectional relationship between the number of remaining teeth, PD, and cognitive function in elderly people.

OBJECTIVES: This study aimed to investigate the perception of dental outpatient care quality from multiple perspectives of administrators, physicians, nurses, and patients and propose nursing care quality evaluation indices that are consistent with the clinical reality to provide reference for the construction of a scientific, systematic, and comprehensive dental outpatient care quality evaluation system. METHODS: A total of 39 interviewees, including 7 administrators, 11 doctors, 11 nurses, and 10 patients, were selected for semi-structured in-depth interviews in five regionally representative tertiary-level A stomatological specialty hospitals nationwide during January-April 2024 by using a multistage sampling method. Colaizzi 7-step analysis was used to analyze and summarize the interview data. Themes were extracted on the basis of the Structure-Process-Outcome (SPO) three-dimensional quality assessment model. RESULTS: Five main themes and 15 secondary themes were extracted from three quality dimensions: structure, process, and result. The related topics of structural quality were as follows: disinfection and isolation norms, equipment and consumable management, nursing manpower ratio and nurse education structure, and emergency capability. The related topics of process quality were as follows: pre-diagnosis risk assessment, patient triage and guidance, communication and attitude, health education, humanistic care, continuous care, specialty operation, and four-hand operation. The related topics of result quality were as follows: satisfaction, adverse event management and analysis, effective complaints and disputes. CONCLUSIONS Structure quality is the foundation, process quality is the core, and result quality is the key in the evaluation of the quality of oral outpatient care. The standardization of disinfection and isolation, equipment and consumable management, allocation of reasonable nursing manpower and post capacity, implementation of high-quality nursing services, and improvement of the quality and satisfaction of medical cooperation are necessary guarantees to ensure the quality of oral outpatient care.

OBJECTIVES: This study aimed to construct an evaluation index system for nursing quality management in outpatient dental clinics based on the structure-process-outcome model and provide an objective standard for the evaluation of nursing quality in outpatient dental clinics. METHODS: Through literature review, multi-subject interviews, and expert meetings, the first draft of the evaluation index for nursing quality management in outpatient dental clinics was formulated. The Delphi method was adopted to select and invite 15 experts in the fields of hospital infection management, nursing management, and specialized oral care from across the country to modify the first draft. RESULTS: The positive coefficients of the experts in the two rounds of consultation were 86.7% and 92.3%, respectively. The total authority coefficients of the experts were 0.791 and 0.717, respectively. The mean scores of the importance and feasibility of the third-level indices in the two rounds of consultation were all ≥4.333; the coefficients of variation were all ≤0.150; and the Kendall's coordination coefficients were 0.308 and 0.184 respectively, with P<0.05 for all. These results indicated that the experts were motivated to participate in this study. They recognized the importance and feasibility of the overall items in this index system, and their opinions were relatively consistent. Finally, an evaluation index system, which included 3 first-level indices, 7 second-level indices, 22 third-level indices, and 69 index connotations, for nursing quality management in outpatient dental clinics was determined. The weights of the three first-level indicators were all 0.333. Patient satisfaction (0.076, outcome dimension), hand hygiene (0.061, outcome dimension), chair care ratio (0.057, structural dimension), and turnover rate (0.057, structural dimension) were the top tertiary indicators in terms of portfolio weight. CONCLUSIONS The construction method of the evaluation index system for nursing quality management in outpatient dental clinics is scientific and reliable. It can provide a reference for the evaluation of the management level of nursing quality in outpatient dental clinics and promote the continuous improvement of nursing quality in outpatient dental clinics.

Objective:To delineate clinical characteristics of infantile myofibroma/myofibromatosis (IM) .Methods:A retrospective analysis was conducted on histologically confirmed IM cases from Beijing Children's Hospital, Henan Children's Hospital, and Maternity and Child Health Care of Guangxi Zhuang Autonomous Region between August 2014 and July 2021. The clinical, pathological, imaging features, and outcomes were analyzed and summarized.Results:A total of 44 IM patients were included, comprising 28 males (63.6%) and 16 females (36.4%). Their ages at onset ( M[ Q1, Q3]) were 14.8 (4.7, 42.4) months, and 26 patients (59.1%) developed IM before the age of 1 year. Seven patients (15.9%) were initially diagnosed with IM. Skin involvement occurred in 42 patients (95.5%), of whom 30 (71.4%) presented with a solitary lesion and 12 (28.6%) with multiple lesions. Skin lesions mainly manifested as painless, firm nodules or masses. The most commonly involved extracutaneous site was the skeletal system (21/44, 47.7%). Histopathological examination of all 44 IM cases revealed a biphasic architecture pattern, characterized by the coexistence of two distinct morphologies or cell types within the tumor tissues (including spindle cell areas composed of fascicularly and densely arranged myofibroblasts, and primitive mesenchymal cell areas composed of small, round undifferentiated cells. Immunohistochemical study was performed in 42 cases; 40 (95.2%) were positive for smooth muscle actin, and 20 (47.6%) were positive for CD34. Genetic testing was conducted in 3 cases, and NOTCH mutations were identified in 2. Among the 44 patients, 30 patients (68.2%) underwent surgical excision, 5 patients (11.4%) received intralesional injections of triamcinolone acetonide, 1 patient (2.3%) received chemotherapy for intestinal involvement, and 8 patients were managed expectantly. During the follow-up of 49 (36, 60) months, lesions completely resolved in 42 cases (95.5%), while 2 cases died of pulmonary infection following chemotherapy or postoperative airway compression. Conclusions:IM predominantly affected infants and young children, with the skin and skeletal system being the most commonly involved sites. Skin lesions often manifested as firm nodules or masses, and histopathological examination was crucial for definitive diagnoses. Most IM cases exhibited favorable outcomes.

Objective:To investigate the association between exposed cardia glands and gastroesophageal reflux disease (GERD) and identify risk factors for exposed cardia glands.Methods:Patients who underwent gastroscopy at Chengde Central Hospital from December 2023 to March 2024 were prospectively enrolled. Patients with exposed cardia glands meeting inclusion criteria comprised the observation group, while controls had no exposed cardia glands but met identical criteria. Demographic, lifestyle, and endoscopic characteristics were compared between the two groups.Results:A total of 204 patients were included in the observation group, while 310 in the control group. Univariate analysis demonstrated statistically significant differences between the observation group and the control group in the following factors: body mass index, waist circumference, smoking, alcohol consumption, tea/coffee intake, spicy food preference, sleeping posture, use of calcium channel blockers, Helicobacter pylori infection, peptic ulcer disease, and GERD ( P<0.05). Binary logistic regression analysis identified the following independent risk factors for exposed cardia glands: waist circumference ( P=0.012, OR=1.070, 95% CI: 1.015-1.129), alcohol consumption ( P=0.003, OR=2.166, 95% CI: 1.293-3.631), spicy food preference ( P=0.048, OR=1.611, 95% CI: 1.004-2.582), right-side sleeping posture ( P<0.001, OR=3.219, 95% CI: 1.696-6.108), use of calcium channel blockers ( P<0.001, OR=3.871, 95% CI: 2.263-6.621), Helicobacter pylori infection ( P<0.001, OR=3.512, 95% CI: 1.953-6.317), and GERD ( P<0.001, OR=2.905, 95% CI: 1.829-4.613) .Conclusion:Exposed cardia glands demonstrates significant association with GERD. Key independent risk factors include waist circumference, alcohol consumption, spicy diet, right-side sleeping position, calcium channel blockers use, and Helicobacter pylori infection.

Severe open tibiofibular fractures account for approximately 28.1% of all open fractures. Among them, Gustilo-Anderson type IIIB/C fractures present significant clinical challenges due to associated bone and soft tissue defects, high infection rates, and risk of amputation. Inadequate preoperative assessment may lead to suboptimal emergency surgical planning or intraoperative complications. Historically, external fixation was often preferred, but this approach has been associated with limitations such as restricted joint mobility, delayed bone union, joint stiffness, and disuse osteoporosis, resulting in poor functional recovery. With advancements of debridement techniques, standardization of antibiotic use, and popularization of early soft tissue coverage, early internal fixation has gained broader acceptance. Nevertheless, controversies persist regarding the choice of fixation method, timing of definitive fixation, use of reamed versus unreamed intramedullary nailing, and necessity of fibular fixation. To standardize the diagnosis and early management of severe open tibiofibular fractures, reduce complication rates, and improve functional recovery, the Society of Microsurgery of the Chinese Medical Association organized a panel of domestic experts to develop the Evidence-based guideline for the diagnosis and early fixation of severe open tibiofibular fractures ( version 2025), using evidence-based methodology. The guidelines provided 12 recommendations covering diagnostic and early fixation strategies of severe open tibiofibular fractures, aiming to provide clinicians with scientifically grounded and standardized guidance.

Senile trichiasis is primarily manifested by eyelid laxity, decreased horizontal elasticity and tension of the eyelids, leading to friction between the eyelashes and the cornea, which subsequently causes corneal damage and vision decline. Surgical intervention remains the most effective therapeutic approach for senile trichiasis. This article elaborates on the epidemiological characteristics, pathological mechanisms, and clinical manifestations of senile trichiasis and systematically reviews the surgical treatment method for upper and lower eyelid trichiasis, including traditional surgical techniques and emerging minimally invasive procedures combined with personalized therapies. Through a literature review, the effectiveness and recurrence rates of surgical treatment are summarized, emphasizing the importance of preoperative assessment and individualized treatment. Additionally, strategies and recommendations for preventing senile trichiasis are proposed.

Objective To investigate the association between birth weight and dementia risk and the mediating roles of chronic diseases,and to assess potential biological pathways underlying the birth weight-associated dementia risk based on large-scale proteomics.Methods We used data from 279 743 participants aged 40 to 69 years enrolled in the UK Biobank.Birth weight was categorized into low birth weight(≤2 500 g),normal birth weight(2 500-3 999 g),and macrosomia(≥4 000 g).Multivariable Cox proportional hazards regression models were used to assess the associations between birth weight categories and all-cause dementia and its subtypes(Alzheimer's disease and vascular dementia).Proteomics analyses were conducted to identify proteins and the potential pathways involved.Results Low birth weight was associated with higher risks for all-cause dementia and its subtypes.The hazard ratios were 1.18(95%CI,1.08-1.30)for all-cause dementia,1.14(95%CI,1.00-1.31)for Alzheimer's disease,and 1.22(95%CI,1.01-1.48)for vascular dementia.A non-linear relationship was observed between birth weight and dementia risk(P for nonlinearity<0.001).Certain cardiometabolic diseases in middle-aged adults,such as diabetes,stroke,hypertension,and dyslipidemia,played a significant mediating role in the relationship between low birth weight and dementia risk,with the mediation proportion being 6.3%to 15.8%.Proteomic analyses identified 21 proteins linked to both low birth weight and all-cause dementia risk,which were significantly enriched in the pathways for viral protein interaction with cytokines and cytokine receptors,adipocytokine signaling,and cytokine-cytokine receptor interaction.Conclusion Low birth weight is positively associated with dementia risk.Cardiometabolic diseases in middle-aged adults may mediate the relationship between low birth weight and dementia risk.A number of proteins and the associated pathways underscore the relationship between low birth weight and dementia risk.

BACKGROUND: The available evidence regarding the benefits of percutaneous coronary intervention (PCI) on patients receiving dialysis with coronary artery disease (CAD) is limited and inconsistent. This study aimed to evaluate the association between PCI and clinical outcomes as compared with medical therapy alone in patients undergoing dialysis with CAD in China. METHODS: This multicenter, retrospective study was conducted in 30 tertiary medical centers across 12 provinces in China from January 2015 to June 2021 to include patients on dialysis with CAD. The primary outcome was major adverse cardiovascular events (MACE), defined as a composite of cardiovascular death, non-fatal myocardial infarction, and non-fatal stroke. Secondary outcomes included all-cause death, the individual components of MACE, and Bleeding Academic Research Consortium criteria types 2, 3, or 5 bleeding. Multivariable Cox proportional hazard models were used to assess the association between PCI and outcomes. Inverse probability of treatment weighting (IPTW) and propensity score matching (PSM) were performed to account for potential between-group differences. RESULTS: Of the 1146 patients on dialysis with significant CAD, 821 (71.6%) underwent PCI. After a median follow-up of 23.0 months, PCI was associated with a 43.0% significantly lower risk for MACE (33.9% [ n  = 278] vs . 43.7% [ n  = 142]; adjusted hazards ratio 0.57, 95% confidence interval 0.45-0.71), along with a slightly increased risk for bleeding outcomes that did not reach statistical significance (11.1% vs . 8.3%; adjusted hazards ratio 1.31, 95% confidence interval, 0.82-2.11). Furthermore, PCI was associated with a significant reduction in all-cause and cardiovascular mortalities. Subgroup analysis did not modify the association of PCI with patient outcomes. These primary findings were consistent across IPTW, PSM, and competing risk analyses. CONCLUSION This study indicated that PCI in patients on dialysis with CAD was significantly associated with lower MACE and mortality when comparing with those with medical therapy alone, albeit with a slightly increased risk for bleeding events that did not reach statistical significance.
