ABSTRACT
Kombucha, originated in China 2000 years ago, is a sour and sweet-tasted drink, prepared traditionally through fermentation of black tea. During the fermentation of kombucha, consisting of mainly acidic compounds, microorganisms, and a tiny amount of alcohol, a biofilm called SCOBY forms. The bacteria in kombucha has been generally identified as Acetobacteraceae. Kombucha is a noteworthy source of B complex vitamins, polyphenols, and organic acids (mainly acetic acid). Nowadays, kombucha is tended to be prepared with some other plant species, which, therefore, lead to variations in its composition. Pre-clinical studies conducted on kombucha revealed that it has desired bioactivities such as antimicrobial, antioxidant, hepatoprotective, anti-hypercholestorelomic, anticancer, anti-inflammatory, etc. Only a few clinical studies have been also reported. In the current review, we aimed to overhaul pre-clinical bioactivities reported on kombucha as well as its brief compositional chemistry. The literature data indicate that kombucha has valuable biological effects on human health.
ABSTRACT
Objective: to describe the main recommended actions on prevention actions related to occupational exposure of health professionals working at COVID-19, available until March 2020. Content: The current pandemic disease caused by the new SARS-CoV-2 coronavirus has its transmission favored by close and unprotected contact with secretions or excretions from infected patients, mainly through salivary droplets. Organizational prevention practices should be prioritized, since patient's arrival at the health service, optimizing the flow of care, the first care and during health care actions, to minimize occupational exposure to the biological agent. Health professionals classified as a risk group should be removed from activities at risk of contamination. Those contaminated or adulterated must remain in quarantine to minimize the spread of COVID-19. Final considerations: care to avoid contamination of workers in this pandemic by the new coronavirus must be prioritized, prevented from affecting the assistance to the population that seeks assistance in health services. © 2020, Centro de Estudos da Faculdade de Enfermagem da UERJ.
