Question | Answer |
---|---|
asymptomatic | without symptoms |
lead-time bias | early detection without improved outcome |
false positives | individuals have positive results on a screening test but do not turn out to have the disease |
false negative | those who have negative results on the screening test but turn out to have the disease |
sequential testing (two-stage testing) | screenings that require two or more tests |
epidemiological transition | the transition from communicable disease to noncommunicable disease as a country becomes more developed |
screening | tests on individuals who are asymptomatic |
multiple risk factor reduction | this strategy intervenes simultaneously in a series of risk factors all of which contribute to a particular outcome, such as lung cancer |
cost-effectiveness | concept that combines issues of benefits and harms with issues of financial costs |
net-effectiveness | implies that benefits are substantially greater than the harms even after the value |
gene-environment protection | genetic testing that identifies individulas who are especially likely to develop disease when they experience specific environmental exposures, such as workers who are exposed to low dose chemicals |
genetic prevention | incorporates efforts to prevent the occurrence of single genes or multiple gene combinations that are likely to produce disease |
genetic detection prior to disease | includes efforts aimed at detection of genetic defects and implementation of early intervention to prevent phenotypic expression of genes. Managed during childhood. |
phenotypic expression of genes | when bad genetics show up in children |
genotypic-based screening for early disease | identifies groups that are at high risk of common disease and that can be targeted for screening. |
