Myopenia-a new universal term for muscle wasting
Journal of Cachexia, Sarcopenia and Muscle
|April 9, 2011
Summary
A new term, myopenia, is proposed for clinically relevant muscle wasting in any illness or age group. This term aims to improve medical intervention for muscle wasting beyond its common association with aging.
Area of Science:
- Gerontology
- Muscle Physiology
- Clinical Medicine
Background:
- Clinically relevant muscle wasting requires a universal medical term for intervention.
- Current term 'sarcopenia' is often limited to age-associated muscle loss in the elderly.
Purpose of the Study:
- To propose a new, universal term for clinically relevant muscle wasting.
- To define 'myopenia' as a distinct medical condition applicable across all ages and illnesses.
Main Methods:
- Literature review and conceptual definition.
- Proposal of diagnostic criteria for myopenia.
Main Results:
- The term 'myopenia' is suggested for clinically relevant muscle wasting.
- Proposed definition: muscle wasting associated with impaired function or increased morbidity/mortality risk.
- Potential diagnostic thresholds include >5% muscle loss in 6-12 months or specific low mass index values.
Conclusions:
- Myopenia offers a specific and translatable term for muscle wasting.
- Further research is needed to refine disease-specific diagnostic criteria and clinical relevance thresholds.

01:28Disorders of the Skeletal Muscle
The clinical conditions affecting the skeletal muscle tissue are broadly categorized as musculoskeletal and neuromuscular disorders.
Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...

01:19Type I Diabetes III: Clinical Manifestations
Type 1 diabetes mellitus typically presents with rapid-onset symptoms due to the body’s inability to utilize glucose in the absence of insulin. Since insulin is required for glucose uptake into cells, its deficiency leads to hyperglycemia and cellular energy deprivation, resulting in characteristic clinical features.Polyuria and PolydipsiaOne of the earliest, most prominent symptoms is polyuria (excessive urination). When blood glucose concentrations rise above the renal threshold, the kidneys...
01:21Overview of Protein Metabolism
Proteins are broken down into amino acids during digestion. Unlike fats and carbohydrates, which are stored for later use, proteins are not. Instead, amino acids are either used to produce ATP through oxidation or contribute to the creation of new proteins for the growth and repair of the body. Any surplus amino acids from the diet are converted into glucose or triglycerides rather than excreted.
Amino acids play various roles in the body once they are absorbed into cells. They are restructured...

01:15Overview of Skeletal Muscle
Skeletal muscles are composed of a bundle of muscle fibers and are attached to bones through tendons. Each skeletal muscle fiber is a single muscle cell. The sarcolemma, the plasma membrane of a skeletal muscle cell, consists of a lipid bilayer and glycocalyx that supports muscle fibers. The sarcolemma extends into the muscle cells to form tubular structures called transverse or T-tubules. Each side of the T-tubules consists of a membrane-bound structure called the sarcoplasmic reticulum,...
01:26Cross-bridge Cycle
As muscle contracts, the overlap between the thin and thick filaments increases, decreasing the length of the sarcomere—the contractile unit of the muscle—using energy in the form of ATP. At the molecular level, this is a cyclic, multistep process that involves binding and hydrolysis of ATP, and movement of actin by myosin.
01:24Obesity
The Body Mass Index (BMI) is a numerical value derived from a person's weight and height, used to categorize individuals into weight ranges. It is calculated using the formula: weight in kilograms divided by height in meters squared. Obesity is a health condition characterized by excessive accumulation of adipose tissue that poses health risks, often diagnosed with a BMI ≥ 30. This excess fat storage occurs when surplus dietary calories are converted into triglycerides and stored in adipocytes...
