  • However, the underlying pathological process may already have been set in train, markers of this process may be apparent, salient risk exposures may be measured, and the diagnosis may thus have the potential to be brought forward in time (fig 1). (bmj.com)
  • Recent studies from the U.K. show that low levels of vitamin D 3 (cholecalciferol) are associated with increased risk of depression and panic. (westonaprice.org)
  • Since EDF primarily focused on exposure (whether lead was detectable or not), we were interested to see if we could get a better sense of the magnitude of risk. (sott.net)
  • 7 These stark results likely underestimate the actual risk, because infants were not screened for lead, and the blood lead levels may have peaked prior to the researchers' measurements. (westonaprice.org)
