Some complications include autonomic dysreflexia, bladder distension, bone infection, pyarthrosis, sepsis, amyloidosis, anemia, urethral fistula, gangrene and very rarely malignant transformation (Marjolin's ulcer – secondary carcinomas in chronic wounds).
Recurring infections by latent herpes viruses can exhaust the immune system of elderly persons. [12] Consistent, repeated stimulation by such pathogens leads to preferential differentiation of the T-cell memory phenotype, and a 2020 review reported that CD8+ T-cell precursors, specific for the most rare and less frequently present antigens shed ...
Compared to other tissues in the body, the brain is deemed unusually sensitive to oxidative damage. [24] Increased oxidative damage has been associated with neurodegenerative diseases, mild cognitive impairment and individual differences in cognition in healthy elderly people. In 'normal aging', the brain is undergoing oxidative stress in a ...
Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly. [3]
Geriatrics, or geriatric medicine, [1] is a medical specialty focused on providing care for the unique health needs of the elderly. [2] The term geriatrics originates from the Greek γέρων geron meaning "old man", and ιατρός iatros meaning "healer".
Wound healing refers to a living organism's replacement of destroyed or damaged tissue by newly produced tissue.

When the barrier is broken, a regulated sequence of biochemical events ...
"The other problem is it's slightly political as well, so some retailers would want to steer clear of it." While Trump has said he plans to move forward with tariffs, some economists have pointed ...
Thymic involution is the shrinking of the thymus with age, resulting in changes in the architecture of the thymus and a decrease in tissue mass. [1] Thymus involution is one of the major characteristics of vertebrate immunology, and occurs in almost all vertebrates, from birds, teleosts, amphibians to reptiles, though the thymi of a few species of sharks are known not to involute.
