Cytostatics occupational exposure: genotoxic effects assessment
Ladeira, Carina; Viegas, Susana; Carolino, Elisabete; Gomes, M. C.; Brito, MiguelThe use of cytostatics drugs in anticancer therapy is increasing. Health care workers can be occupationally exposed to these drugs classified as carcinogenic, mutagenic or teratogenic. Workers may be exposed to this drug, being in the hospital settings the main focus dwelled upon the pharmacy, and nursing personnel. Although the potential therapeutic benefits of hazardous drugs outweigh the risks of side effect...
Biomonitorization in hospital settings with cytostatics occupational exposure
Ladeira, Carina; Viegas, Susana; Carolino, Elisabete; Gomes, M. C.; Brito, MiguelExposure in a hospital setting is normally due to the use of several antineoplastic drugs simultaneously. Nevertheless, the effects of such mixtures at the cell level and on human health in general are unpredictable and unique due to differences in practice of hospital oncology departments, in the number of patients, protection devices available, and the experience and safety procedures of medical staff. Health...
Application of alkaline comet assay in human biomonitoring for genotoxicity: a ...
Ladeira, Carina; Viegas, Susana; Carolino, Elisabete; Gomes, M. C.; Brito, MiguelThe use of cytostatics drugs in anticancer therapy is increasing. Health care workers can be occupationally exposed to these drugs classified as carcinogenic, mutagenic or teratogenic. Cytostatics drugs are a heterogeneous group of chemicals widely used in the treatment of cancer, nevertheless have been proved to be also mutagens, carcinogens and teratogens. Workers may be exposed to this drug, being in the hos...
Dynamics and control of measles in Portugal: Accessing the impact of anticipati...
Paulo, A. C.; Gomes, M. C.; Gomes, M. G. M.The all-time low incidence of measles in Portugal in the recent years, raises questions regarding whether the disease has been eliminated, the role of recent control measures, and the epidemiological consequences of the rise in the proportion of newborns to vaccinated mothers, as opposed to those born to mothers who acquired immunity by natural infection. We estimate the vaccination coverage against measles in ...
The reinfection threshold promotes variability in tuberculosis epidemiology and...
Gomes, M. G. M.; Franco, A. O.; Gomes, M. C.; Medley, G. F.Population patterns of infection are determined largely by susceptibility to infection. Infection and vaccination induce an immune response that, typically, reduces susceptibility to subsequent infections. With a general epidemic model, we detect a 'reinfection threshold', above which reinfection is the principal type of transmission and, consequently, infection levels are much higher and vaccination fails. The...
