Osteosarcopenia: beyond age-related muscle and bone loss.

European Geriatric Medicine

Abstract

Osteosarcopenia is a geriatric syndrome characterized by declines in bone density and microarchitecture and muscle mass and strength, which has gained clinical interest due to its association with falls and fragility fractures. This review discusses the epidemiology of osteosarcopenia including clinical assessment, the pathophysiological aspects leading to the loss of muscle and bone mass, and efficacious therapeutic strategies to combat this syndrome. The etiology of osteosarcopenia is thought to include genetic and environmental factors which interact with muscle and bone at the cellular level, reinforcing that these tissues are interconnected not only by mechanical aspects, but also by humoral factors. Osteosarcopenia is identified by low muscle and bone mass and impaired strength of these tissues via imaging and physical performance measures. The diagnosis of osteosarcopenia is of clinical importance since early interventions, particularly resistance exercise, and adequate intake of protein, vitamin D and calcium, may delay the onset of individual components (osteopenia/sarcopenia) of osteosarcopenia.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Blastomycosis

Blastomycosis fungal infections spread through inhaling Blastomyces dermatitidis spores. Discover the latest research on blastomycosis fungal infections here.

Nuclear Pore Complex in ALS/FTD

Alterations in nucleocytoplasmic transport, controlled by the nuclear pore complex, may be involved in the pathomechanism underlying multiple neurodegenerative diseases including Amyotrophic Lateral Sclerosis and Frontotemporal Dementia. Here is the latest research on the nuclear pore complex in ALS and FTD.

Applications of Molecular Barcoding

The concept of molecular barcoding is that each original DNA or RNA molecule is attached to a unique sequence barcode. Sequence reads having different barcodes represent different original molecules, while sequence reads having the same barcode are results of PCR duplication from one original molecule. Discover the latest research on molecular barcoding here.

Chronic Fatigue Syndrome

Chronic fatigue syndrome is a disease characterized by unexplained disabling fatigue; the pathology of which is incompletely understood. Discover the latest research on chronic fatigue syndrome here.

Evolution of Pluripotency

Pluripotency refers to the ability of a cell to develop into three primary germ cell layers of the embryo. This feed focuses on the mechanisms that underlie the evolution of pluripotency. Here is the latest research.

Position Effect Variegation

Position Effect Variagation occurs when a gene is inactivated due to its positioning near heterochromatic regions within a chromosome. Discover the latest research on Position Effect Variagation here.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

Microbicide

Microbicides are products that can be applied to vaginal or rectal mucosal surfaces with the goal of preventing, or at least significantly reducing, the transmission of sexually transmitted infections. Here is the latest research on microbicides.
