The application of unilateral or bilateral permanent prostheses to the labium majus in the external genitalia of women for reconstructive and aesthetic purposes may make it appear fuller. The labium majus may lose its fullness and symmetry due to menopause, rapid weight gain and loss, traumas, cancers, and infectious diseases. Aesthetic interventions (e.g., hyaluronic acid filler injection and fat grafting) aiming to provide the labium majus with fullness have become very popular in recent years. The hyaluronic acid filler is used for reconstructive purposes to achieve fullness in labium majus. However, the maximum amount that can be injected is 3 mL, which is often insufficient for the desired outcome and its effect lasts for a maximum of 1 year. Autologous fat grafting is administered by taking 18–120 mL of fat from patients themselves; however, its effect usually lasts 1 to 4 years. The application of a prosthesis will provide labium majus with fullness and this effect will be long-lasting. The outer edge of the prosthesis is convex and the inner edge is concave. In male genitalia, prostheses have been used since 1950 to provide the testicles with fullness. Scientific studies have shown that these prostheses positively affect self-confidence and body perception indices in men.

Oncology faces a digital chasm in its quest for personalized treatments. Despite the adoption of electronic health records (EHR), most hospitals are ill-equipped for data science research. Embodiments herein describe a continuously learning infrastructure through which multimodal health data are systematically organized and data quality is assessed with the goal of applying artificial intelligence to address unmet clinical needs. Embodiments describe systems and methods for improved cancer prognostics, including by obtaining electronic medical records and performing natural language processing thereon. Additional embodiments apply term frequency inverse document frequency to identify terms that are predictive for cancer survival. Additional embodiments are capable of performing in silico clinical trials based on information comprised in a collection of health records.

The invention discloses application of ergothioneine as a biomarker in preparation of rheumatoid arthritis diagnosis products, and belongs to the field of biomedicine. According to the invention, the content of ergothioneine in a sample is detected through high performance liquid chromatography-tandem mass spectrometry, so that diagnosis of rheumatoid arthritis of a patient is realized. Through analysis, the AUC (area under curve) of the ergothioneine in distinguishing the RA group from the OA group is 0.7880, and the AUC in distinguishing the RA group from the HC group is 0.8804, which indicates that the ergothioneine has good diagnostic value. According to the technical scheme, a new biomarker is provided for rheumatoid arthritis, a basis is provided for further examination of clinicians, important scientific research and clinical application values are achieved, and a practical means is provided for diagnosis of RA.

The application discloses a small-scale perception enhanced human posture estimation method, which draws on the shortcomings of previous models, optimizes the performance of small-scale targets, selects a more accurate Top-down structure, discards the heat map representation method, and uses SimCC based on one-dimensional vector representation to more accurately locate the key points of small-scale targets, and a TAA module is further proposed based on the SimCC-baseline, and the effectiveness of the TAA module is verified through an ablation experiment, and finally good results are achieved in the overall AP. The performance of small-scale targets greatly limits the improvement of the overall accuracy of the model, and most of the previous networks ignore this point, so the SSA-Net has practical application value and scientific research value.
