Vocal Biomarkers

A vocal biomarker is a feature or a combination of features from an audio signal of a voice that is associated with a clinical outcome. Vocal biomarkers can be used to diagnose a condition, monitor patients, or grade the stages or the severity of the disease or for drug development. Various clinical researches are exploring the use of voice or vocal biomarkers to identify the causes of both mental and neurological disorders. This technology can also be used to detect diseases, as well as monitor patients and improve the quality of care.

The Global Vocal Biomarkers Market size is expected to be valued at US$ 1,357.7 million in 2019, and is expected to exhibit a CAGR of 15.5% over the forecast period (2019 – 2027).

Psychiatric and neurological disorders, such as Alzheimer's disease and Parkinson's disease, are a major cause of death worldwide. The Alzheimer's Association has also called for faster research on biomarkers for early diagnosis of the disease, so that the disease can be treated before symptoms occur. Researchers have identified the biomarker that could help physicians diagnose Alzheimer's disease earlier. Researchers have identified a biomarker that could help physicians diagnose AD earlier, as a patient transitions into mild cognitive impairment.

Voice can serve as a useful tool in identifying the risk or presence of various medical conditions such as coronary artery disease, depression, Parkinson’s disease, and more. Vocal biomarkers are signals that can be detected in the voice, and are linked to a variety of disorders, such as coronary artery disease, anxiety, and depression. These biomarkers can be also identified during diagnosis of cognitive impairment, respiratory disorders, Alzheimer's disease, traumatic brain injury, and are generally used to detect diseases using speech features in a non-invasive way.

Vocal biomarkers can be an advanced innovation in the field of medical diagnostics, allowing for minimally-invasive diagnostic procedures to detect chronic conditions. Thus, with the increase in prevalence of chronic diseases, the use of vocal biomarkers is also increasing rapidly. According to the Centers for Disease Control and Prevention (CDC), chronic diseases, such as heart disease, cancer, and diabetes, are the leading causes of death and disability in the U.S.

Bispecific Antibodies Are Used As Therapeutic Drugs While Treating Viral Infections, Oncology, And Auto-Immune Diseases

Image
  Bispecific Antibodies Bispecific antibodies are produced through cell fusion or recombinant DNA technologies. Bispecific antibodies are much more specific than monoclonal antibodies. Their applications in tumor immunotherapy are nearly limitless. As of today, seven bispecific antibodies have been approved by the FDA and EMA and over one hundred are in preclinical testing. Bispecific antibodies were initially developed using the quadroma technology. They contain two distinct antigen-binding arms, which enable them to bind to the target antigen while also activating an effector cell, which kills tumor cells. The primary antigen on the surface of the effector cell is called CD3, which is a popular target of immune cells. According to Coherent Market insights the Bispecific Antibodies Market Global Industry Insights, Trends, Outlook, and Opportunity Analysis, 2022-2028. Many of these multi specific antibody formats have been developed over the past 30 years. These categories ...
