Facioscapulohumeral muscular dystrophy (FSHD) is a type of muscular dystrophy, a group of heritable diseases that cause degeneration of muscle and progressive weakness. Per the name, FSHD tends to sequentially weaken the muscles of the face, those that position the scapula, and those overlying the humerus bone of the upper arm.
In 2016, the WHO recorded 56.7 million deaths [3] with the leading cause of death as cardiovascular disease causing more than 17 million deaths (about 31% of the total) as shown in the chart to the side. In 2021, there were approx. 68 million deaths worldwide, as per WHO report.
It links the muscle membrane to the thin muscular filaments within the cell. Dystrophin is an integral part of the muscular structure. An absence of dystrophin can cause impairments: healthy muscle tissue can be replaced by fibrous tissue and fat, causing an inability to generate force. [4] Respiratory and cardiac complications can occur as well.
Heart disease and cancer are still the leading causes of death For more than 100 years, heart disease has been the number one No. 1 cause of death in the U.S, and the pandemic has done nothing to ...
Human infectious diseases may be characterized by their case fatality rate (CFR), the proportion of people diagnosed with a disease who die from it (cf. mortality rate).It should not be confused with the infection fatality rate (IFR), the estimated proportion of people infected by a disease-causing agent, including asymptomatic and undiagnosed infections, who die from the disease.
Preliminary numbers suggest that the United States is on track to see more than 3.2 million deaths this year. U.S. deaths in 2020 top 3 million, the most ever counted Skip to main content
A CFR, in contrast, is the number of deaths among the number of diagnosed cases only, regardless of time or total population. [ 3 ] From a mathematical point of view, by taking values between 0 and 1 or 0% and 100%, CFRs are actually a measure of risk ( case fatality risk ) – that is, they are a proportion of incidence , although they do not ...
Biopsy shows general dystrophic features, such as areas of muscle death, variability in muscle size, nuclei in the center of muscle fibers, and disorganized muscle fibers within muscle cells. [ 3 ] Serum creatine kinase , a nonspecific marker of muscle damage, can be elevated early in the disease.
