1. Principal components analysis of agitation outcomes in Alzheimer's disease.

    Journal of Psychiatric Research 79:4 (2016) PMID 27115509 PMCID PMC4891245

    We developed a composite measure of agitation as a secondary outcome of change over time in the Citalopram for Agitation in Alzheimer's disease study (CitAD). CitAD demonstrated a positive effect of citalopram on agitation on the Neurobehavioral Rating Scale agitation subscale (NBRS-A). CitAD in...
  2. Negative Tuberculin Skin Test and Prediction of Reversion of QuantiFERON Interferon Gamma Release Assay in US Healthcare Workers.

  8. Nocturia reported in nightly sleep diaries: common occurrence with significant implications?

    Health Psychology 33(11):1362 (2014) PMID 24245840 PMCID PMC4119089

    Nocturia (nocturnal awakenings associated with urination) is so common a nocturnal behavior that its association with poor sleep is often overlooked. This study examined nocturia and its potential role in poor sleep by examining reported nightly awakenings and associated bathroom trips. Sleep di...

No data are currently available on the longitudinal stability of S...
  13. Effects of body mass index-related disorders on cognition: preliminary results.

    Diabetes Metabolic Syndrome and Obesity Targets... 7:145 (2014) PMID 24855383 PMCID PMC4020904

    Well-known risk factors for cognitive impairment are also associated with obesity. Research has highlighted genetic risk factors for obesity, yet the relationship of those risk factors with cognitive impairment is unknown. The objective of this study was to determine the associations between cog...
