The application of precision medicine in the field of tuberculosis is still in its infancy. The precision medicine of tuberculosis cannot be separated from the rapid and accurate diagnosis, the effective anti-tuberculosis drugs, and the comprehensive application of new cutting-edge technologies. In recent years, the precision medicine of tuberculosis has focused on drug-resistant tuberculosis, host-directed therapy and nano-targeted therapy, which has achieved certain results, providing an important mean for the treatment of tuberculosis, especially for the drug-resistant tuberculosis. In the future, the development of new drugs and the application of emerging technologies are the focus of precision medicine of tuberculosis. It is necessary to gradually carry out relevant clinical trial research and objectively evaluate its application value and prospects.
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.
ObjectivesTo initially construct a scientific, reasonable and precision medicine technology value judgment framework suitable for China’s national conditions based on expert consultation method, so as to provide scientific value judgment system support for China's medical insurance decision-making.MethodsThe preliminary evaluation indicator system for precision medicine technology value was established by using literature analysis and expert consultation method, and the direct weighting method was used to determine the indicators weight.ResultsAfter two rounds of expert consultation, an indicator system suitable for the value judgment of precision medicine technology in China was constructed, including 5 primary indicators (health needs, health effects, economics, innovation and suitability) and 14 secondary indicators. Each indicator was weighted according to importance.ConclusionsA set of precision medicine value judgment indicator system suitable for China has been initially established, which lays a certain foundation for further measurement research of the indicator system and provides a scientific basis for medical insurance decision-making.
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.
Breast cancer is one of the most common malignant tumors among women. Typically, the operation of breast cancer should include breast surgery and axillary lymph node surgery since breast cancer first metastasizes to regional axillary lymph nodes. However, postoperative breast cancer-related lymphedema (BCRL) in upper limb is the most common long-term complication. The injury to upper limb lymphatic system contributes to causing the postoperative BCRL. Therefore, precision medicine in the extent of axillary lymph node surgery plays an important role in preventing BCRL which can improve the quality of life in breast cancer patients.
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.
Precision medicine is a personalized medical system based on patients' individual biological information, clinical symptoms and signs, forming a new clinical research model and medical practice path. The basic idea of traditional Chinese medicine and the concept of precision medicine share many similarities. The basket trial developed for precision medicine is also suitable for clinical trials and evaluation of the efficacy of traditional Chinese medicine syndrome differentiation and treatment systems. Basket trials are used to evaluate the efficacy of a drug in the treatment of multiple diseases or disease subtypes. It has the advantages of sharing a master protocol, unifying management of subsidiary studies, simplifying the test implementation process, unifying statistical analysis, saving resources, reducing budgets and accelerating the drug evaluation progress. This is similar to the concept of using the "same treatment for different diseases" found in traditional Chinese medicine. This paper introduced the concept and method of basket trials and explored their application and advantages in clinical research into traditional Chinese medicine. This study is expected to provide references for the methodological innovation of clinical research into traditional Chinese medicine.
Precision medicine is an individualized clinical research model established according to gene, environment, lifestyle and other information. As an innovative method of clinical trials, the main scheme design breaks the barriers of traditional randomized controlled trials to the evaluation of targeted therapies in precision medicine and improves the efficiency of clinical research. This paper will systematically introduce the types, concepts and principles of the main scheme design of the new method of precision medicine clinical trial design, and summarize the advantages and limitations of the main scheme design combined with classic cases, aiming at providing scientific and rigorous methodological guidance and clinical practice experience for precision medicine scientific research design.
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.
ObjectiveTo summarize current patient-derived organoids as preclinical cancer models, and its potential clinical application prospects. MethodsCurrent patient-derived organoids as preclinical cancer models were reviewed according to the results searched from PubMed database. In addition, how cancer-derived human tumor organoids of pancreatic cancer could facilitate the precision cancer medicine were discussed. ResultsThe cancer-derived human tumor organoids show great promise as a tool for precision medicine of pancreatic cancer, with potential applications for oncogene modeling, gene discovery and chemosensitivity studies. ConclusionThe cancer-derived human tumor organoids can be used as a tool for precision medicine of pancreatic cancer.
