With the advancement of research on rare ocular diseases such as inherited retinal dystrophy (IRD) has advanced in recent years, especially breakthroughs in therapeutic approaches represented by cell and gene therapy, potential intervention strategies have emerged for these conditions. Establishing standardized endpoints and evaluation methods for visual function in patients with IRD has become crucial for assessing disease progression, safety, and therapeutic efficacy of innovative treatments. Best corrected visual acuity (BCVA) is widely recognized as one of the primary endpoints for assessing visual function. However, for IRD patients with severe rod photoreceptor dysfunction, who often present with profound low vision or even legal blindness, the applicability of BCVA as a traditional visual function indicator is limited. The multi-luminance mobility test (MLMT) has emerged as a functional visual assessment tool that evaluates the ability to navigate obstacle courses under varying illumination levels. By establishing graded evaluation standards, MLMT objectively quantifies the impact of lighting conditions on patients’ nobility and spatial orientation, providing a novel quantitative tool for assessing visual function in IRD clinical trials. Currently, there is a lack of unified and standardized guidelines for the use of MLMT in China, posing challenges to its implementation in practical clinical research. To address this, Ocular Fundus Disease Society of Chinese Medical Association and Chinese Medical Doctor Association convened a multidisciplinary team comprising clinical experts in genetic retinal diseases, statisticians, and optical specialists to investigate the current applications and technical characteristics of MLMT, ultimately formulating consensus recommendations for its use as a clinical trial endpoint for IRD gene therapies. This consensus aims to provide a set of MLMT operating norms applicable to China's national conditions, guide clinical practice and research in ophthalmology and related disciplines, and promote the standardization process of IRD clinical trials in China, so as to better serve the IRD patient population and promote the development of related fields.
This consensus aims to introduce the applications of 4K high-definition technology and fluorescence technology in thoracic surgery, summarize and categorize the technical support for pulmonary segment surgery, and innovatively propose technical support for precise sleeve resection of pulmonary segments. It provides a reference for clinical use, points out the direction for the research and innovation of domestically produced high-end endoscopes, promotes the widespread application of excellent domestically produced medical endoscopes, and facilitates the development of domestically produced medical equipment.
Infiltrative optic neuropathy (ION) is characterized by the infiltration of tumor cells or inflammatory cells in the optic nerve and its sheath. ION is rare in clinic practice, and ION caused by direct infiltration or metastasis of malignant tumors is easily misdiagnosed as optic perineuritis or optic neuritis, which means delayed proper treatment and makes patients risking possible side effects of steroid therapy. Currently, ophthalmologists are lack of sufficient knowledge about ION, which contributes to the high rate of misdiagnosis and missed diagnosis of ION in clinical practice. The diagnosis and treatment of ION have not yet formed systematic standardized guidelines. Therefore, Neuro-ophthalmology Group of Ophthalmology Branch of Chinese Medical Association organized experts to propose consenus of opinions on definition, diagnosis and treatment of ION, which helps to guide clinical diagnosis and treatment of ION, as well as basic researches about ION.
The consensus was authored by National Society of Congenital Heart Diseases. After employing the Delphi process and incorporating literature reviews and expert discussions, seven recommendations were ultimately formulated. The consensus provides a detailed elaboration on the pathoanatomy, pathophysiology, clinical manifestations, diagnostic methods, and surgical treatment approaches for aortic valve diseases in children. It emphasizes that the treatment of aortic valve diseases in children should take into account the needs of growth and development, and recommends surgical strategies for different age groups and types of lesions, including valve plasty, Ross procedure, valve replacement, and balloon dilation. Specifically, aortic valve plasty is recommended for neonates and infants, while surgical options for older children are more diversified. The consensus only discusses isolated aortic valve disease and does not cover cases complicated with other heart malformations.
Choroideremia (CHM) is a rare X-linked recessive genetic inherited degeneration. Affected males present with progressively worsening night blindness, visual field loss, and decreased central vision, which can cause blindness in middle age. Although female carriers typically exhibit mild symptoms, it is essential to understand their clinical features for early diagnosis of patients as well as genetic counseling of family members. The pathogenesis of CHM remains incompletely understood, and currently there is no approved effective treatment. To enhance clinicians’ comprehension of CHM and establish standardized clinical approaches to its diagnosis and management, the Chinese Hereditary Ocular Disease Diagnosis and Treatment Group and the Chinese Hereditary Ocular Disease Alliance assembled authoritative experts, through in-depth discussions, formed China's standardized recommedations for the on clinical diagnosis and treatment of CHM. The purpose of this advice is to provide a standardized diagnostic framework, monitoring indicators, and an integrated management strategy for clinicians to use in practice, thereby optimizing the care and genetic guidance for patients with CHM.
Transcatheter aortic valve replacement (TAVR) is effective in the treatment of severe symptomatic aortic stenosis and its applicable population is also gradually expanding, but it carries risk of ischemic and bleeding events, which underscores the importance of optimizing adjuvant antithrombotic regimens. The release of the 2022 version of Chinese expert consensus on antithrombotic therapy after transcatheter aortic valve implantation has promoted the standardized and safe development of antithrombotic therapy after TAVR in China. Combined with the latest progress of antithrombotic therapy after TAVR, from emphasizing ischemia and bleeding risk assessment, single-agent antiplatelet therapy for patients without anticoagulation indications, the selection of antithrombotic strategies for patients with other antithrombotic indications, antithrombotic strategy changes in postoperative valve thrombosis and bleeding events, this article interprets this consensus.
To investigate the anatomical classification, diagnosis, indications, surgical methods, surgical techniques, intraoperative management, postoperative management and surgical efficacy of mitral valve malformation. Using the internationally used Delphi procedure, PubMed, Medline, The Cochrane Library, Wanfang and other databases were searched to review domestic and foreign literatures on congenital mitral valve deformity from January 1940 to February 2020, and select the ones of higher quality as evidence. In addition, with regard to the multiple disputes in the diagnosis and treatment of congenital mitral valve, experts from pediatric cardiac surgery and related disciplines have been convened for discussion for many times, and finally the following consensus has been formed to guide the clinical treatment and provide theoretical and technical guidance for the surgical treatment of congenital mitral valve malformation in China.
Objective To evaluate the methodological quality of clinical practice guidelines and consensuses of robot-assisted surgery. Methods The guidelines and consensuses were screened according to the inclusion and exclusion criteria by searching the domestic and overseas guidelines network and electronic database from 1 January, 2000 to 29 December, 2021. The Appraisal of Guidelines for Research and EvaluationⅡ (AGREEⅡ) instrument was used independently by two evaluators to evaluate the guidelines and consensuses. The consistency test of intraclass correlation coefficient (ICC) was carried out for two evaluators, and the score of guidelines and consensuses in the six domains of AGREEⅡ were calculated. Results A total of 34 guidelines and consensuses were included, including 10 guidelines and 24 consensuses. The ICC was all greater than 0.75, indicating that the consistency of the two evaluators was high. The average scores of the 34 guidelines and consensuses in the six domains of AGREEⅡ (scope and purpose, stakeholder involvement, rigor of development, clarity of presentation, applicability and editorial independence) were 81.0%, 43.5%, 28.2%, 81.5%, 12.7% and 51.7%, respectively. Conclusion These evaluated guidelines and consensuses of robot-assisted surgery still need to be improved in the domains of rigor of development, applicability and editorial independence. With the continuous development of robot-assisted surgery, more guidelines and consensuses based on higher level of evidence will be developed to promote the standardized use of robot-assisted surgery.
Perioperative mechanical ventilation plays a role in lung injury and postoperative pulmonary complications, yet a consensus in the literature concerning the key clinical question of how to best provide lung protection during mechanical ventilation in surgical patients is lacking. It is necessary to develop an expert consensus on perioperative mechanical ventilation suitable for Chinese anesthesiologists to better guide clinical practice. The experts from the Anesthesia Committee of Chengdu Medical Association and the Chongqing Medical Association Anesthesiology Branch were organized by West China Hospital of Sichuan University to propose the question regarding the perioperative mechanical ventilation, and the current literature was then reviewed, and expert opinions were solicited to provide evidence-based guidance. Subsequently, the expert panel reached a consensus and formulated 28 recommendations with evidence of moderate to high quality using the modified Delphi method.
