Abstract:
Frailty is a common condition in older people. It now can be objectively defined by the Fried criteria. When recognized, early intervention should begin with the institution of endurance, resistance, and balance exercises. In men with testosterone deficiency a trial of testosterone replacement should be considered. Vitamin D deficiency needs to be recognized and treated. Appropriate treatment of underlying diseases, such as anemia, diabetes mellitus, and congestive heart failure, are a key management principle. In people who have frailty aggressive health promotion and disease prevention techniques can lead to an inhibition of the downward spiral to disability.

Bone Disorders
Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...

Cellular Clock Theory
The cellular clock theory posits that the human lifespan is closely tied to the finite capacity of cells to divide, a phenomenon governed by telomeres, which are protective caps at the ends of...
Flail Chest-I
Flail chest is a severe and potentially life-threatening condition characterized by the fracture of three or more adjacent ribs in multiple places. It is most commonly caused by direct impacts and trauma, such as motor vehicle accidents or injuries from a steering wheel impact. It can also occur due to falls in elderly individuals with osteoporosis, or assaults involving sharp objects.
Pathophysiology
The pathophysiology of flail chest is complex, involving fractures of...
