متن کاملLight sensors for objective light measurement in ambulatory polysomnography
Ambulatory polysomnography (PSG) does not commonly include an objective measure of light to determine the time of lights off (Loff), and thus cannot be used to calculate important indices such as sleep onset latency and sleep efficiency. This study examined the technical specifications and appropriateness of a prototype light sensor (LS) for use in ambulatory Compumedics Somte PSG.Two studies w...
متن کاملLight level and duration of exposure determine the impact of self-luminous tablets on melatonin suppression.
Exposure to light from self-luminous displays may be linked to increased risk for sleep disorders because these devices emit optical radiation at short wavelengths, close to the peak sensitivity of melatonin suppression. Thirteen participants experienced three experimental conditions in a within-subjects design to investigate the impact of self-luminous tablet displays on nocturnal melatonin su...
متن کاملAge-related maculopathy and sunlight exposure evaluated by objective measurement
AIM To study the relationship between age-related maculopathy (ARM) and exposure to sunlight using an objective method. METHODS In a case-control study of Japanese men aged > or = 50 years (67 controls without ophthalmic disease and 148 with ARM), those with ARM were separated into groups of early (n = 75) and late (n = 73) ARM. Facial wrinkle length and area of hyperpigmentation, which are c...
متن کاملObjective Measures of Prenatal Alcohol Exposure: A Systematic Review.
CONTEXT Objective measurement of prenatal alcohol exposure (PAE) is essential for identifying children at risk for adverse outcomes, including fetal alcohol spectrum disorders. Biomarkers have been advocated for use in universal screening programs, but their validity has not been comprehensively evaluated. OBJECTIVE To systematically review the validity of objective measures of PAE. DATA SO...
