We examine 31,011 PPY23 profiles at the population, metapopulation and world levels. Most haplotypes appear only once but a few have higher counts, including a set of 23 matching profiles in Delhi, India and a set of 16 matching profiles in Burkina Faso with one additional matching American African profile. We estimate Fvalues to be used as "theta" (θ) in match probability calculations, following the method we used in our earlier survey of autosomal STR data.

We address the estimation of these coefficients as well as other relationship parameters that derive from them such as kinship and inbreeding coefficients using a concise matrix framework. Estimation of the Jacquard coefficients via likelihood methods and the expectation-maximization algorithm is computationally very demanding for large numbers of polymorphisms.

Methods: We analyzed baseline data from PrEP eligible PWID in Baltimore, MD. Risk perception was assessed by PWID relative to the average risk of their age group categorized as: higher-than, lower-than, or about average.
Introduction: The purpose of this study was to simulate potential changes in dietary intake and food costs by replacing juice with whole fruit among children ages 1-5 years attending U.S. early care and education settings between 2008 and 2020.
