Knee joint osteoarthritis, a chronic condition resulting in considerable disability, particularly in later life, not only impacts life quality significantly and severely, but is also strongly associated with the persistence of intractable pain, depression, helplessness, and a high falls injury risk. This narrative overview synthesizes the knowledge base regarding painful knee osteoarthritis and what is known about Tai Chi exercise participation in the context of reducing knee joint disability and its associated risk of one or more injurious falls, as well as pain and depression. To this end, all relevant articles published in the English language on the topic were sought. While most reports rely on Eastern observations, rather than Western medicine studies, collectively, these data reveal that Tai Chi practiced widely in Asia for many centuries may have an enormous positive impact on reducing distress and increasing function and autonomy among older adults living in the community and diagnosed as having knee osteoarthritis. They specifically suggest the increasing numbers of older adults diagnosed as having knee osteoarthritis can safely practice selected Tai Chi exercises with the expectation that consistent applications will enhance mobility, reduce pain and depression, plus instability and possible injurious falls, while reducing fatigue, even if surgery is forthcoming.

This editorial aims to propose and delineate that disciplined open-air exercise can slow down aging in humans. The aging process may be slowed down by outdoor physical training (e.g., mountaineering, climbing, running, swimming, walking, jogging) mainly because of fresh air inhalation and psychological calmness. However, for outdoor exercise to be a healthy asset, it should be performed in unpolluted and uncontaminated environments. Advanced public education policies must be developed to persuade people to maximize their outdoor physical activities. This is to ensure achieving peace and serenity for both body and psych. Integrated social activities may also be encouraged with open-air exercise. As such, stress in the third millennium can be pragmatically attenuated and managed. As a result of slower aging process, human life quality may improve worldwide. Show less

Efforts to mitigate or prevent painful disabling osteoarthritis have been pursued for more than a century with limited success. This current overview briefly summarizes how selected beliefs and behaviors, including coping and stress management approaches are potential mediators or moderators of osteoarthritis pain and its overall common adverse prognosis and outcome. Published data housed predominantly in PUBMED, PUBMED CENTRAL, SCIENCE DIRECT, and GOOGLE SCHOLAR sites and pertaining to selected aspects of the literature of current interest, cumulative results reported as of May 30, 2024, show a modest to strong rationale exists for considering the abovementioned factors in efforts to reduce pain and enable daily functions. Accordingly this line of research should be continued, and translated clinically without undue delay, especially in the face of increases in the aging population and osteoarthritis prevalence and undue suffering.

From an academic and clinical point of view, stem cell therapy represents one of the most promising advances in modern medicine, with the ability to partially induce the regeneration of acutely injured or chronically damaged tissues. Stem cell research provides new opportunities for the treatment of various conditions, among them diabetes mellitus, HIV, cardiovascular diseases, and neurodegenerative illnesses. Stem cell therapy is currently not FDA-approved in the US (except for certain blood cancers). While bioethics and religion have mostly discussed the source of cells, i.e., embryonic cells that require the destruction of embryos versus adult tissue for research purposes, we also discuss the controversies with regard to currently offered therapies, and marketing of unapproved procedures from a scientific, clinical, and religious viewpoint.
