Mixed reality technology is new digital holographic imaging technology that generates three-dimensional simulation images through computers and anchors the virtual images to the real world. Compared with traditional imaging diagnosis and treatment methods, mixed reality technology is more conducive to the advantages of precision medicine, helps to promote the development of medical clinical application, teaching and scientific research in the field of orthopedics, and will further promote the progress of clinical orthopedics toward standardization, digitization and precision. This article briefly introduces the mixed reality technology, reviews its application in the perioperative period, teaching and diagnosis and treatment standardization and dataization in the field of orthopedics, and discusses its technical advantages, aiming to provide a reference for the better use of mixed reality technology in orthopedics.
Basing on development of medical model, new national diagnostic standard is interpreted according to three aspects: classification, diagnostic standard, and diagnostic contents. Tracheobronchial tuberculosis and tuberculous pleurisy are added into the classification. The value of molecular and pathological techniques for diagnosis of the pulmonary tuberculosis is emphasized. The status of drug-resistance is included in the diagnostic content. Two opinions are suggested: some practical methods such as diagnostic chemotherapy are indicated in some grassroots areas, while new molecular techniques for detection of DNA/RNA of mycobacteria and resistant mutation are encouraged in some suitable institutions.
Tuberculosis (TB) is one of the major public health concerns worldwide. Since the development of precision medicine, the filed regarding TB control and prevention has been brought into the era of precision medicine. Although great progress has been achieved in the accurate diagnosis, treatment and management of TB patients, we have to face several challenges. We should seize the opportunity, and develop and improve novel measures in TB prevention on the basis of precision medicine. The accurate diagnosis criteria, treatment regimen and management of TB patients should be carried out according to the standard of precision medicine. We aim to improve the treatment of TB patients and prevent the transmission of TB in the community, thereby contributing to the achievement of the End TB Strategy by 2035.
Precision medicine is a novel medical modality based on genome sequencing, bioinformatics and big data science. The studies regarding tuberculosis always concentrated on the bacteria and host in the setting of precision medicine. This review mainly introduces the application of precision medicine in the diagnosis and treatment of tuberculosis. The limits of the Chinese studies with respect to precision medicine in tuberculosis are also discussed. Moreover, the article predicates its future development.
Abstract Precision medicine is an ideal medical paradigm which combines modern scientific methods with traditional medical methods to diagnose, treat and evaluate the physical function and nature of diseases more precisely, and to maximize health benefits and minimize the risk of individuals and society with the most effective, safest, and the most economical medical service. Evidence-based medicine is necessary to verify the precision of diagnosis and treatment. In this review, we clarified the conception of precision medicine and the relation between precision medicine and evidence-based medicine. Moreover, we reviewed the application of precision medicine in the field of cerebrovascular disease. We pointed out that such new technologies as genetics, bioinformatics, molecular imaging and management provided tools to realize the idea of precision medicine, and high-quality evidence-based studies provided a guarantee for the clinical practice of precision medicine. In summary, precision medicine is an individualized medical mode that based on the context of a patient's genetic information, living environment and clinical data, etc. to provide precise treatment strategies for the prevention and treatment of disease, but still the promotion of precision medicine should be based on clinical validation under the guidance of evidence-based medicine. Thus, long-term exploration and unremitting efforts are required to achieve the idea of precision medicine.
The "All of Us" research program is a research project supported by the National Institutes of Health. By recruiting over 1 million volunteers residing in the United States, the project builds a strong research resource to promote the exploration of biological, clinical, social, and environmental determinants of health and disease. This paper introduced the design plan of the "All of Us" research program systematically and provided information that can be used for the construction of a million natural population cohort of precision medicine in China.
The umbrella trial has received increasing attention in the design of clinical trials for oncology drugs in recent years. This trial design categorizes a single disease into multiple sub-types based on predictive biomarkers or other predictive factors, and simultaneously evaluates the efficacy of multiple targeted therapies. When compared with the traditional drug development model of phase Ⅰ, phaseⅡ, and phase Ⅲ randomized controlled trials, umbrella trials are a more scientifically rigorous trial design that can speed up drug evaluation to address the conflict between numerous untested drugs and diseases with a lack of effective treatment options. This article will focus on the concept, main characteristics, eligibility criteria, design and statistical considerations, ethical considerations, and future directions of umbrella trials, with the aim of providing methodological guidance for the design of clinical trials for oncology drugs.
Retinitis pigmentosa (RP) is an inherited retinal disease characterized by degeneration of retinal pigment epithelial cells. Precision medicine is a new medical model that applies modern genetic technology, combining living environment, clinical data of patients, molecular imaging technology and bio-information technology to achieve accurate diagnosis and treatment, and establish personalized disease prevention and treatment model. At present, precise diagnosis of RP is mainly based on next-generation sequencing technology and preimplantation genetic diagnosis, while precise therapy is mainly reflected in gene therapy, stem cell transplantation and gene-stem cell therapy. Although the current research on precision medicine for RP has achieved remarkable results, there are still many problems in the application process that is needed close attention. For instance, the current gene therapy cannot completely treat dominant or advanced genetic diseases, the safety of gene editing technology has not been solved, the cells after stem cell transplantation cannot be effectively integrated with the host, gene sequencing has not been fully popularized, and the big data information platform is imperfect. It is believed that with the in-depth research of gene sequencing technology, regenerative medicine and the successful development of clinical trials, the precision medicine for RP will be gradually improved and is expected to be applied to improve the vision of patients with RP in the future.
Precision medicine is a medical paradigm founded on individual genetic information amalgamated with extensive clinical data to offer patients precise diagnoses and treatments. Genetic testing forms the cornerstone of accurate diagnosis, and skilled professionals in fields like clinical medicine, molecular biology, and bioinformatics play a crucial role in realizing the potential of precision medicine. This paper presents reference suggestions for the continuing education approach for relevant technical personnel. The main emphasis is on conducting routine face-to-face and hands-on training to enhance theoretical knowledge and professional skills. Secondly, there is a need to modify the training approach by reinforcing molecular biology, bioinformatics, and other courses, enhancing assessment methods, gradually implementing specialized training in precision medicine subspecialties, and ensuring effective clinical practice and management of precision medicine.
