Geriatric Respondents and Non-Respondents to Probiotic Intervention Can be Differentiated by Inherent Gut Microbiome Composition

SCOPE Probiotic interventions are known to have been shown to influence the composition of the intestinal microbiota in geriatrics. The growing concern is the apparent variation in response to identical strain dosage among human volunteers. One factor that governs this variation is the host gut microbiome. In this study, we attempted to define a core gut metagenome, which could act as a predisp...

Test of a Web and Paper Employee Satisfaction Survey: Comparison of Respondents and Non-Respondents

This study examined if administering an employee satisfaction survey using the Internet affected the rates or quality of employees’ participation. 644 hospital employees were randomly assigned to complete a satisfaction survey using either a Web survey or a traditional paper measure. Response rates were relatively high across both modes. No evidence for a very large difference in response rates...

Comparison of mortality between respondents and non-respondents in a mail survey.

We conducted a population-based mail survey and prospectively compared mortality between respondents and non-respondents. Age-adjusted mortality rates for all causes were higher among non-respondents than among respondents in both sexes. Age-adjusted rate ratios were 1.50 for males and 1.33 for females. Non-respondents also had, in both sexes, higher mortality for three leading causes of death,...

Method of sampling in a study of older people with a comparison of respondents and non-respondents.

Edinburgh is divided into 23 city wards in 10 of which one of us (J.W.) and colleagues provide a geriatric service. The sample was drawn from these 10 wards, contact being made with persons in the sample through their general practitioners. Ninetyfive general practitioners were working in 50 practices with premises in this area. The plan was explained to the doctors, 91 of whom agreed to co-ope...
