The Use of Biologic Treatments for Osteoarthritis: A Review

Open Journal of Regenerative Medicine 2024年第2期13卷 21-40页

作者： William Thornton Sion Glyn-jones Nuffield Department of Orthopaedics Rheumatology and Musculoskeletal Sciences University of Oxford Oxford UK

Background: The number of people presenting with osteoarthritis is increasing due, largely, to an ageing population and advances in medical treatments. This is driving the demand for new clinical solutions and treatments for the disease. Biologic therapies have been touted as an adjunct, or even alternative to established treatments for osteoarthritis. The term “biologics” refers to protein-based therapeutics that are derived from the proteins of living organisms. These treatments include, but are not limited to: autologous blood products such as platelet rich plasma (PRP), cell therapies such as autologous chondrocyte implantation (AcI) and mesenchymal stem cells, growth factors and cytokines, gene therapy. Aim: This study aims to provide a clear definition of these technologies and describe the evidence supporting their clinical efficacy to treat osteoarthritis. This is to provide clarity to both clinicians and patients on the range of technologies available. Method: Literature databases Embase and PubMed were searched for keywords such as “biologic”, “osteoarthritis”. Results: The literature identified 4 primary categories of biologic treatments for osteoarthritis: stem cell therapy, somatic cell therapy, protein therapy and gene therapy. The evidence level varied in its quality from treatment to treatment, as did the conclusions of published studies. conclusion: Autologous chondrocyte therapy had the most convincing evidence to support its use as a treatment for osteoarthritis, however, current methods of use produced variable results. Other treatments such as platelet rich plasma and bone marrow derived stem cells show promise as potential future therapies, with more refinement, but evidence does not support their use currently. Other treatments including autologous stem cells should be avoided until there is a greater quantity and quality of evidence supporting their use.

Use of ketamine for severe asthma exacerbation in a pregnant patient with persistent bronchospasm: A case report

引用

Emergency and critical care Medicine 2024年第3期4卷 130-133页

作者： Johnson M. Abbas M. Abdo J. Mansour M. jones J. Pharmacy Department Beaumont Health Dearborn MI United States Emergency center Beaumont Health Dearborn MI United States

Background Estimated 4%-8% of pregnancies are complicated by asthma. Adequate management in this population is critical to minimize complications. Patients presenting with asthma exacerbation are typically managed with standard bronchodilators and systemic corticosteroids. However, additional agents may be used in patients with refractory asthma exacerbation. Ketamine has been used in refractory bronchospasm, although its efficacy in published literature is heterogeneous. case Presentation We present a case of a pregnant patient with severe asthma exacerbation refractory to standard and salvage treatment who achieved termination of bronchospasm with ketamine infusion. conclusion After receiving ketamine infusion for several days, the patient had improved air flow and achieved successful extubation, without experiencing rebound bronchospasm. Although this individual clinical case alone cannot change guidelines or directives to use in refractory asthma exacerbations, it offers a possible treatment option to patients and providers in unusually severe cases with extenuating risk factors. © Wolters Kluwer Health, Inc.

Performance of evolutionary optimized machine learning for modeling total organic carbon in core samples of shale gas fields

引用

Petroleum 2024年第1期10卷 150-164页

作者： Leonardo Goliatt c.M.Saporetti L.c.Oliveira E.Pereira Department of computational and Applied Mechanics Federal University of Juiz de Fora Department of computational Modeling Polytechnic Institute Rio de Janeiro State University Petrobras Department of Stratigraphy and Paleontology Rio de Janeiro State University

Rock samples' TOc content is the best indicator of the organic matter in source rocks. The origin rock samples' analysis is used to calculate it manually by specialists. This method requires time and resources because it relies on samples from many well intervals in source rocks. Therefore, research has been done to aid this effort. Machine learning algorithms can estimate total organic carbon instead of well logs and stratigraphic studies. In light of these efforts, the current work present a study on automating the total organic carbon estimation using machine learning approaches improved by an evolutionary methodology to give the model flexibility and precision. Genetic algorithms, differential evolution, particle swarm optimization, grey wolf optimization, artificial bee colony, and evolution strategies were used to improve machine learning models to predict TOc. The six metaheuristics were integrated into four machine learning methods: extreme learning machine, elastic net linear model, linear support vector regression, and multivariate adaptive regression splines. core samples from the YuDong-Nan shale gas field, located in the Sichuan basin, were used to evaluate the hybrid strategy. The findings show that combining machine learning models with an evolutionary algorithms in a hybrid fashion produce flexible models that accurately predict TOc. The results show that, independent of the metaheuristic used to guide the model selection, optimized extreme learning machines attained the best performance scores according to six metrics. Such hybrid models can be used in exploratory geological research,particularly for unconventional oil and gas resources.
