Sports disciplines and the risk of shoulder dislocation

The shoulder joint is a mechanism that can provide movement in multiple directions, but precisely because of the versatility of the structure in excursion and mobility, the shoulder also presents an aspect of fragility, being exposed to a continuous risk of injury or dislocation.

Brain tumor: what to know

Brain tumors do not have typical symptoms because they induce disorders common to many other diseases of the nervous system. These symptoms depend on the size of the tumor and

Alzheimer’s: a new blood test will allow diagnosis many years in advance

Among the many critical issues related to Alzheimer’s disease, one concerns the difficulty of diagnosing it in its early stages. Although research has not yet identified a viable therapeutic approach, diagnostically the situation may soon change with the development of a blood test that scientists say can Diagnose up to 94 percent of Alzheimer’s cases 20 years earlier That the symptoms of the disease occur. The researchers in question are from Washington University in St Louis and described the test in the journal Neurology.
The disease is characterized by the increase ofbeta-amyloid plaques in the brain, associated with the accumulation of tau protein tangles, and the test proposed by the U.S. researchers relies precisely on the measurement of beta-amyloid in the blood, which would correlate with that in the brain .
The idea is not new and is a refinement of a technique already presented two years ago; it uses mass spectrometry to measure beta-amyloid-or, more precisely, the ratio between two forms of the protein, called A-β 42 and A-β 40 – and associates its blood concentration with two fundamental risk factors for developing Alzheimer’s: advanced age and the presence of a genetic variant called APOE4.
In this way, the accuracy of the test outperforms that of previous blood tests.
The team recruited 158 adults over the age of 50; all but 10 were described as cognitively normal. Each participant underwent at least one blood test and one PET scan with amyloid tracers , which is the current gold standard, and each test was labeled as amyloid positive or amyloid negative depending on the results produced.
Among experts, there is a growing consensus that in order to manage or treat Alzheimer’s, it is important to intercept it as early as possible, before symptoms begin to appear and the brain is not too damaged.
More than for a cure, which is not currently available, the test could further research. Today, to conduct clinical trials, we check people with scans, which is time-consuming and expensive, whereas with a blood test we could easily examine a large number of subjects, which would help us find treatments more quickly, with a huge potential impact.
