ObjectiveTo elucidate the critical role of rehabilitation medical records (including electronic records) in rehabilitation medicine's clinical practice and management, comprehensively analyzed the structure, core content and data standards of rehabilitation medical records, to develop a standardized medical record data architecture and core dataset suitable for rehabilitation medicine and to explore the application of rehabilitation data in performance evaluation and payment. MethodsBased on the regulatory documents Basic Specifications for Medical Record Writing and Basic Specifications for Electronic Medical Records (Trial) issued by National Health Commission of China, and referencing the World Health Organization (WHO) Family of International Classifications (WHO-FICs) classifications, International Classification of Diseases (ICD-10/ICD-11), International Classification of Functioning, Disability and Health (ICF), and International Classification of Health Interventions (ICHI Beta-3), this study constructed the data architecture, core content and data standards for rehabilitation medical records. Furthermore, it explored the application of rehabilitation record summary sheets (home page) data in rehabilitation medical statistics and payment methods, including Diagnosis-related Groups (DRG), Diagnosis-Intervention Packet (DIP) and Case Mix Index. ResultsThis study proposed a systematic standard framework for rehabilitation medical records, covering key components such as patient demographics, rehabilitation diagnosis, functional assessment, rehabilitation treatment prescriptions, progress evaluations and discharge summaries. The research analyzed the systematic application methods and data standards of ICD-10/ICD-11, ICF and ICHI Beta-3 in the fields of medical record terminology, coding and assessment. Constructing a standardized data structure and data standards for rehabilitation medical records can significantly improve the quality of data reporting based on the medical record summary sheet, thereby enhancing the quality control of rehabilitation services, effectively supporting the optimization of rehabilitation medical insurance payment mechanisms, and contributing to the establishment of rehabilitation medical performance evaluation and payment based on DRG and DIP. ConclusionStructured rehabilitation records and data standardization are crucial tools for quality control in rehabilitation. Systematically applying the three reference classifications of the WHO-FICs, and aligning with national medical record and electronic health record specifications, facilitate the development of a standardized rehabilitation record architecture and core dataset. Standardizing rehabilitation care pathways based on the ICF methodology, and developing ICF- and ICD-11-based rehabilitation assessment tools, auxiliary diagnostic and therapeutic systems, and supporting terminology and coding systems, can effectively enhance the quality of rehabilitation records and enable interoperability and sharing of rehabilitation data with other medical data, ultimately improving the quality and safety of rehabilitation services.

Objective:This study aimed to clarify the clinical characteristics of children infected with rhinovirus in the context of the Corona Virus Disease 2019 (COVID-19) pandemic and to explore the impact of recent COVID-19 infection history on their clinical features.Methods:Clinical data and laboratory test result of 286 children diagnosed with rhinovirus infection at Hangzhou Children′s Hospital from July 2022 to October 2023 were collected. A retrospective survey was conducted to determine whether all study participants had a history of COVID-19 infection within the 6 months prior to hospitalization.Results:Among the 286 children with rhinovirus infection, 180 (62.94%) had simple rhinovirus infection, while 106 (37.06%) had co-infections with other pathogens; Among the 180 rhinovirus simplex-positive children, 56.67% had wheezing symptoms; among them, 15 cases (15/180, 8.33%) were diagnosed with acute asthma attacks; 7 cases (7/180, 3.88%) were diagnosed with severe pneumonia. Based on whether the children had a history of COVID-19 infection in the 6 months prior to hospitalization, they were divided into a group with previous COVID-19 infection and a group without previous COVID-19 infection. There were no significant differences between the two groups in terms of gender, age of onset, peak fever, incidence of wheezing, incidence of pneumonia, proportion of severe pneumonia, proportion of severe asthma attacks, duration of fever, time to relief of wheezing, length of stay, white blood cell count, eosinophil count, C-reactive protein, procalcitonin, immunoglobulin E, oxygen therapy requirements, and use of intravenous steroids ( P>0.05). Conclusions:A history of COVID-19 infection in the past 6 months does not exacerbate the clinical symptoms of children with rhinovirus infection, nor does it increase the incidence of wheezing.

Objective:To investigate the clinical features of nontuberculous mycobacteria (NTM) disease patients with positive anti-interferon γ (IFN-γ) autoantibody.Methods:Forty-three adult human immunodeficiency virus-uninfected patients with NTM disease hospitalized in Huashan Hospital, Fudan University and Jing′an Branch, Huashan Hospital, Fudan University from July 2021 to August 2023 were included. Clinical data and NTM strain information of the patients were collected. The plasma levels of anti-IFN-γ autoantibodies were detected by enzyme-linked immunosorbent assay, and the patients were divided into antibody positive group and antibody negative group. The clinical characteristics and laboratory examination results between the two groups were compared. The independent sample t test, Mann-Whitney U test and chi-square test were used for statistical analysis. Multivariate logistic regression analysis was used to determine the correlation factors of positive anti-IFN-γ autoantibodies. Results:Among the 43 patients, 13 cases (30.2%) were positive for anti-IFN-γ autoantibodies and 30 cases (69.8%) were negative. The proportions of patients with NTM disseminated infection (9/13 vs 30.0%(9/30))and combined bacterial infection (5/13 vs 6.7%(2/30)) in antibody positive group were both higher than those in antibody negative group, and the differences were both statistically significant ( χ2=5.74 and 6.73, respectively, both P<0.05). The white blood cell count, platelet count, the proportion of platelet count >350×10 9/L of antibody positive patients were all higher than those of antibody negative group, while the white sphere ratio was lower than that of antibody negative group, with statistical significance ( t=2.42, 3.02, χ2=9.77 and t=3.66, respectively, all P<0.05). Erythrocyte sedimentation rate, C-reactive protein, procalcitonin, globulin, immunoglobulin G, immunoglobulin A and immunoglobulin M in antibody positive patients were all higher than those in antibody negative group, and the differences were all statistically significant ( U=99.50, 112.00, 115.50, 61.50, 76.50, 99.00 and 83.00, respectively, all P<0.05). Mycobacterium abscessus complex (seven cases and 11 cases, respectively) and Mycobacterium avium complex (five cases and 13 cases, respectively) were the main isolated strains in antibody positive and antibody negative patients. Multivariate logistic regression analysis showed that combined with bacterial infection (odds ratio ( OR)=21.83, 95% confidence interval ( CI) 1.94 to 245.71), NTM disseminated infection ( OR=7.64, 95% CI 1.10 to 53.26), platelet count>350×10 9/L ( OR=14.31, 95% CI 1.91 to 107.04) were risk factors for anti-IFN-γ autoantibodies positive (all P<0.05). Conclusions:Patients with positive anti-IFN-γ autoantibodies have higher probability of having elevated levels of systemic inflammation. Anti-IFN-γ autoantibody test is recommended for patients with NTM disease who present with co-bacterial infection, NTM disseminated infection, or elevated platelet count (>350×10 9/L).

Objective To explore a method to improve the accuracy and generalization ability of medical diagnostic neural network models under conditions of small data volumes,and to address the issue of poor neural network model performance in computer-aided diagnosis of nail diseases due to limited training data.Methods A dual-model strategy integrating instance segmentation with fine-grained feature classification was proposed.The neural network model based on dual-model strategy was trained using the dataset of Image-Based Intelligent Diagnosis of Nail Disease Model task of the first National Digital Health Innovation Application Competition & Health and Medical Big Data Theme Competition.This dataset covered 8 types of nail diseases,including nail matrix nevi,paronychia,nail psoriasis,onychomycosis,subungual hemorrhage,melanonychia,periungual warts,and nail melanoma,with class imbalance present.The diagnostic performance of the dual-model strategy was evaluated and compared with single-model strategies(image classification models[ResNet50 and Swin Transformer]and target detection model based on faster region-based convolutional neural network[Faster R-CNN])under the same hardware and software training conditions.Results The dataset included 1 048 samples,including 210 cases of nail matrix nevi,186 cases of paronychia,69 cases of nail psoriasis,203 cases of onychomycosis,149 cases of subungual hemorrhage,71 cases of melanonychia,93 cases of periungual warts,and 67 cases of nail melanoma,with 90％used for training various models and 10％for evaluation.The micro F1 score was 0.324 in the image classification model based on ResNet50,0.381 in the image classification model based on Swin Transformer,0.572 in the target detection model based on Faster R-CNN,and 0.714 in the dual-model strategy model Mask R-CNN+Swin Transformer.The accuracy rates for diagnosing different nail diseases in the dual-model strategy were:nail matrix nevi 80.95％(17/21),paronychia 89.47％(17/19),nail psoriasis 100.00％(7/7),onychomycosis 70.00％(14/20),subungual hemorrhage 73.33％(11/15),melanonychia 14.29％(1/7),periungual warts 55.56％(5/9),and nail melanoma 42.86％(3/7).The micro F1 score for evaluating the dual-model strategy on a test set of 1 000 cases was 0.844.Conclusion The dual-model strategy can effectively combine models with different functions to well accomplish the task of intelligent diagnosis of nail diseases under small data volume training conditions.

Objective:To investigate the positive rate and isolate Bordetella pertussis in children with suspected whooping cough and their close family members in Zhejiang Province, and further explore the susceptibility and resistant mechanism of Bordetella pertussis to antibiotics. Methods:A total of 273 nasopharynx swabs specimens from children with suspected whooping cough in Hangzhou Children′s Hospital from May 2022 to October 2022 were collected. The strains were isolated and cultured using charcoal select agar plate. Pertussis target genes were detected by RT-PCR. E-test method was used to detect the sensitivity of Bordetella pertussis strains to different antibiotics. The mechanism of resistance of Bordetella pertussis to macrolides was analyzed by whole genome sequencing. The phylogenetic analysis of isolated strains was based on core genome multilocus sequence typing(cgMLST). Results:Among 273 clinical samples of children with suspected pertussis and their close family members, 168 samples were positive by fluorescence quantitative PCR, accounting for 61.54%, and 30 pertussis strains were successfully isolated with a positive rate of 10.98%. In addition, among the 143 samples of close family members, 54.55% (78/143) samples were positive by RT-PCR and 9.79% (14/143) samples were positive by culture, suggesting that the close family member are important in family transmission of pertussis. Besides, most of the positive samples were from mothers. The results of E-test showed that 96.67%(29/30) strains showed high resistance to azithromycin with MIC value>256 mg/L, and the resistant mechanism of azithromycin was A2047G mutation in 23S rRNA. The phylogenetic analysis based on the cgMSLT showed that the isolated strains were clustered into two new different clades.Conclusions:The positive rate of Bordetella pertussis in close family members is at a high level and the mother may be the main source of infection, which is of great significance for monitoring and laboratory detection of suspected children′s family members. Bordetella pertussis shows high resistance to macrolides in Zhejiang Province, so monitoring of the antimicrobial resistance should be further strengthened to provide theoretical basis for clinical treatment and drug guidance.

Objective:To evaluate percutaneous mechanical thrombectomy (PMT) using Aspirex device for treating acute iliofemoral deep vein thrombosis (IFDVT).Methods:The clinical and follow-up data of 68 patients with IFDVT at our institution from Jan 2019 to Jun 2021 was retrospectively analyzed.Results:Twenty-six patients who had received PMT combined with auxiliary catheter directed thrombolysis (CDT) were included into group A, and 42 patients received CDT alone were into group B.The final thrombus clearance rates were more than 50%, and the clinical efficacy of thrombolysis was achieved. Group A associated a significant reduction in lysis duration and UK dosage and hospital days and degree of detumescence after 24 h compared with group B,and all aforementioned differences were statistically significant. Hospitalization costs in group A were more than group B. At one year follow-up, there were no significant differences between the two groups in the cumulative prevalence post-thrombotic syndrome (PTS) and the Villalta score and primary patency (92.0% vs. 90.0% , χ2=0.059, P=0.807). Conclusions:The application of PMT using the Aspirex device for acute IFDVT was safe and effective, which could accelerate the clearance of thrombus, and reduce UK dosage, lysis duration, hospital days. However, it increased the hospitalization costs.

Objective:To observe the multimodal imaging features and explore the treatment of parafoveal exudative vascular anomaly complex (PEVAC).Methods:A retrospective study. Six patients (6 eyes) with PEVAC diagnosed in Tianjin Eye Hospital were included in this study from July 2018 to December 2021. All patients were female with monocular disease. The age was (61.1±9.3) years. All patients showed a sudden painless decline in monocular vision with metamorphopsia. All patients underwent best corrected visual acuity (BCVA), color fundus photography, fundus fluorescein angiography (FFA), optical coherence tomography (OCT) and OCT angiography (OCTA). Indocyanine green angiography (ICGA) was performed in 4 eyes. In 6 eyes, 3 eyes were treated with intravitreal injection of anti-vascular endothelial growth factor drug; 5 eyes were treated with micropulse laser photocoagulation and/or local thermal laser photocoagulation; 1 eye was treated with photodynamic therapy. Five patients were followed up for (9.2±7.4) months, and 1 patient was lost. At follow-up, the same equipment and methods were used as at the initial diagnosis. The clinical manifestations, multimodal image features and treatment response were observed.Results:Baseline BCVA of affected eyes were ranged from 0.1 to 0.5. PEVAC was isolated in 6 eyes, and the fundus showed isolated hemangioma-like leision, accompanied by small bleeding and hard exudation. There were 2 isolated hemangiomatous lesions adjacent to each other in 2 eyes. In the early stage of FFA, punctate high fluorescence lesions near the macular fovea were seen, and the leakage was enhanced in the late stage. There was no leakage in the early stage of ICGA, or slight leakage with late scouring. OCT showed an oval lesion with high reflection wall and uneven low reflection. The central macular thickness (CMT) was (431±76) μm. OCTA showed blood flow signals in PEVAC, 2 eyes in the superficial capillary plexus (SCP), and it was also observed in the deep capillary plexus (DCP), but the intensity of blood flow signal was slightly weaker than that in the SCP. The blood flow signal was visible only in DCP in 2 eyes. SCP and DCP showed similar intensity of blood flow signals in 2 eyes. After treatment, the bleeding was absorbed basically in 4 eyes, the hard exudation partially subsided, the CMT decreased, the intercortical cystic cavity of the fovea nerve decreased, the hemangiomatous lesions narrowed, and BCVA increased. In 1 eye, the macular sac was reduced and partially absorbed by hard exudation, which was later relapsed due to blood pressure fluctuation.Conclusions:The majority of PEVAC patients had monocular onset. The fundus is characterized by solitary or structure with strong reflex walls, with or without retinal cysts, hard exudates, and subretinal fluid, and visible blood flow signals inside.

Objective:To investigate the status and willingness of information disclosure based on social supervision in tertiary and secondary public hospitals, so as to provide reference for expanding information disclosure content.Methods:By using stratified cluster random sampling method, 66 tertiary public hospitals and 126 secondary public hospitals in 6 provinces were selected for questionnaire survey in April 2021. Thirty-one indicators in 3 categories and 5 groups were selected to obtain the information disclosure status and willingness. Chi-square test, variance analysis and paired t-test were used to conduct difference analysis. Results:The indicators with higher disclosure rates in public hospitals were drug prices and medical service price adjustments (93.9% in tertiary hospitals and 92.1% in secondary hospitals) and medical insurance reimbursement policies and compensation processes (90.9% in tertiary hospitals and 86.5% in secondary hospitals), while the indicators with lower disclosure rates were case fatality rates in low-risk groups (24.2% in tertiary hospitals and 26.2% in secondary hospitals), proportion of special needs medical services (27.3% in tertiary hospitals), and average daily outpatient visits per practitioner (27.3% in tertiary hospitals and 26.2% in secondary hospitals). The indicators that public hospitals thought could be disclosed at a higher rate were drug and medical service price adjustments, medical insurance reimbursement policies and compensation processes, and prices and medical insurance reimbursement of commonly used drugs and major medical consumables, while the indicators that were thought to be disclosed at a lower rate were some medical service safety indicators and hospital financial indicators.For all indicators, the percentage that the hospitals thought could be disclosed was higher than the percentage that had been disclosed.Conclusions:At present, China′s secondary and tertiary public hospitals have a low rate of disclosure about medical service efficiency, medical service safety, statistical summary cost and financial indicators. However, except for some medical service indicators and financial related indicators, the hospitals′ information disclosure willingness is relatively high, and the scope of information disclosure can be expanded in an orderly manner in steps.

Objective    To evaluate the early and mid-term results of robot-assisted coronary artery bypass grafting (RACAB) in the treatment of multi-vessel coronary artery disease (MV-CAD). Methods     Patients with MV-CAD who underwent RACAB from April 2018 to December 2021 in our hospital were included. Patients who underwent hybrid coronary revascularization (HCR) which combined RACAB with percutaneous coronary intervention were allocated to a HCR-RACAB group, and patients who underwent multi-vessel RACAB were allocated to a MV-RACAB group. Perioperative and follow-up data were collected and compared between the two groups. Results     A total of 102 patients were included, including 81 males and 21 females with a mean age of 61.7±10.8 years. Two (2.0%) patients were transferred to conventional CABG due to sudden ventricular fibrillation and pleura adhesion. In the remaining 100 patients who underwent RACAB, 100 left internal mammary arteries (LIMA) and 46 right internal mammary arteries (RIMA) were harvested with a 100.0% success rate. Besides, all patients undergoing RACAB achieved LIMA/RIMA-left anterior descending branch reconstruction, with an average number of 2.5±0.6 target vessels revascularized by stent or graft. One patient had perioperative myocardial infarction with an outcome of death. The incidence of major perioperative adverse events was 1.0%. There was no perioperative stroke or re-sternotomy for hemostasis. The mean follow-up time was 28.2 months, with a follow-up rate of 99.0% and an overall major adverse cardiac and cerebrovascular event (MACCE) rate of 7.0%, including 3 all-cause deaths (3.0%), 2 strokes (2.0%) and 3 re-revascularizations (3.0%). The HCR-RACAB group had fewer red blood cell transfusion (P=0.030) and intraoperative blood loss (P=0.037) compared with the MV-RACAB group, and there was no statistical difference in the incidence of major perioperative adverse events or MACCE between the two groups during the follow-up period (P>0.05). Conclusion    RACAB can be safely applied in the treatment of MV-CAD with good early and mid-term outcomes. High-quality harvesting of LIMA/RIMA and aortic no-touch technique are crucial to achieve these results.
