Osteoporosis is a very prevalent disease in the elderly population but not much is known about the optimal prescription and dosage of physical exercise to help prevent bone mineral loss. A lot of the focus around osteoporosis is also prevention and not so much maintenance which should be the front runner when considering what approach to take.
Osteoporosis is defined in women by the World Health Organization as a bone mineral density of 2.5 standard deviations below peak bone mass, relative to the age and sex-matched average. This density is measured using dual energy X-ray absorptiometry (DEXA), with the term "established osteoporosis" including the presence of a fragility fracture ...
Some diseases with symptoms of decreased bone density are osteoporosis, and rickets. Some people who experience increased bone resorption and decreased bone formation are astronauts. Due to the condition of being in a zero-gravity environment, astronauts do not need to work their musculoskeletal system as hard as when on earth. Ossification ...
Osteoporosis occurs when there is an imbalance between the bone resorption activities of osteoclasts and the bone formation activities of osteoblasts. [ 23 ] Osteoclast activity is also mediated by the interaction of two molecules produced by osteoblasts, namely osteoprotegerin and RANK ligand .
A pathologic fracture is a bone fracture caused by weakness of the bone structure that leads to decrease mechanical resistance to normal mechanical loads. [1] This process is most commonly due to osteoporosis, but may also be due to other pathologies such as cancer, infection (such as osteomyelitis), inherited bone disorders, or a bone cyst.
A normal T score is -1.0 and above, low bone density is between -1.0 and -2.5, and osteoporosis is -2.5 and lower. A Z score is just a comparison of what a patient's bone mineral density is in comparison to the average bone mineral density of a male or female of their age and weight.
When diagnosing PTSD, clinicians define a trauma as “actual or threatened death, serious injury, or violence.” While other disturbing experiences can be traumatic, they generally don’t lead ...
Bone marrow adipocytes (BMAds) [9] originate from mesenchymal stem cell (MSC) progenitors that also give rise to osteoblasts, among other cell types. [10] Thus, it is thought that BMAT results from preferential MSC differentiation into the adipocyte, rather than osteoblast, lineage in the setting of osteoporosis. [11]
