New Biomarker Offers Early Detection of ALS and FTD

Two progressively degenerative diseases, amyotrophic lateral sclerosis (ALS, commonly known as Lou Gehrig's disease) and frontotemporal dementia (FTD, recently in the news with the diagnoses of actor Bruce Willis and talk show host Wendy Williams), are linked by more than the fact that they both damage nerve cells critical to normal functioning -; the former affecting nerves in the brain and spinal cord leading to loss of movement, the latter eroding the brain regions controlling personality, behavior and language.

Tuberculosis bacteria found in 90% of symptomatic individuals not officially diagnosed with TB

Mycobacterium tuberculosis (Mtb), the bacterium responsible for tuberculosis infections, is detectable in the exhaled breath of 90% of individuals with suspected tuberculosis, including those who tested negative on conventional sputum tests and were not diagnosed with TB. This suggests a potential risk of transmission among those who have tested negative.
