An evaluation of pharmacogenomic information provided by five common drug information resources

Introduction:

This study evaluated whether pharmacogenomic information contained in the Food and Drug Administration (FDA)–approved package inserts of sixty-five drugs was present in five drug information resources.

Methods:

The study searched for biomarkers from the FDA package inserts in 5 drug information sources: American Hospital Formulary Service Drug Information (AHFS), Facts & Comparisons 4.0 (Facts), ePocrates Online Free (ePocrates Free), Lexicomp Online (Lexicomp), and Micromedex 2.0. Each resource had the opportunity to present biomarker information for 65 drugs, a total of 325 opportunities. A binary system was used to indicate presence or absence of the biomarker information. A sub-analysis was performed on the 13 most frequently prescribed drugs in the United States.

Results:

Package insert biomarker information was available, on average, for 81.5% of the 65 FDA-listed drugs in 2011. Percent availability for the individual resources was: Lexicomp, 95.3%; Micromedex 2.0, 92.3%; Facts, 76.9%; AHFS, 75.3%; and ePocrates Free, 67.7%. The sub-analysis of the 13 top drugs showed Lexicomp and Micromedex 2.0 had the most mentions, 92.3%; ePocrates Free had the least, 53.8%.

Conclusion:

The strongest resource for pharmacogenomic information was Lexicomp. The gap between Lexicomp and ePocrates Free is concerning. Clinicians would miss pharmacogenomic information 6.6 times more often in ePocrates Free than in Lexicomp.

Implications:

Health sciences librarians should be aware of the variation in biomarker availability when recommending drug resources for licensing and use. Librarians can also use this study to encourage publishers to include pharmacogenomics information from the package insert as a minimum standard.     

Distinct Age‐Related Differences in Temporal Discounting and Risk Taking in Adolescents and Young Adults

Age‐related differences in temporal discounting (TD) and risk taking, and their association, were examined in adolescents and young adults (n = 337) aged 12–27 years. Since monetary rewards are typically used in TD and risk‐taking tasks, the association between monetary reward valuation and age and decision making in these tasks was explored as well. TD declined linearly with age, with a particularly sharp decline from 15 to 16 years. In contrast, risk taking was not correlated with age and TD. Reward valuation was not associated with TD and risk taking, and age‐related differences in TD remained significant after controlling for reward valuation. Together, these findings suggest that risk taking and TD are two separate constructs with distinct age‐related differences in adolescence and young adulthood.     

Self‐Socialization of Gender in African American,Dominican Immigrant,and Mexican Immigrant Toddlers

This article advances a self‐socialization perspective demonstrating that children's understanding of both gender categories represents an intergroup cognition that is foundational to the development of gender‐stereotyped play. Children's (N = 212) gender category knowledge was assessed at 24 months and play was observed at 24 and 36 months. Higher levels of gender category knowledge and, more specifically, passing multiple measures of knowledge of both gender categories at 24 months was related to increases in play over time with gender‐stereotyped toys (doll, truck), but not gender‐stereotyped forms of play (nurturing, motion). In contrast to the long‐standing focus on self‐labeling, findings indicate the importance of intergroup cognitions in self‐socialization processes and demonstrate the generalizability of these processes to a diverse sample.     

The Goldilocks Effect in Infant Auditory Attention

Infants must learn about many cognitive domains (e.g., language, music) from auditory statistics, yet capacity limits on their cognitive resources restrict the quantity that they can encode. Previous research has established that infants can attend to only a subset of available acoustic input. Yet few previous studies have directly examined infant auditory attention, and none have directly tested theorized mechanisms of attentional selection based on stimulus complexity. This work utilizes model‐based behavioral methods that were recently developed to examine visual attention in infants (e.g., Kidd, Piantadosi, & Aslin, 2012). The present results demonstrate that 7‐ to 8‐month‐old infants selectively attend to nonsocial auditory stimuli that are intermediately predictable/complex with respect to their current implicit beliefs and expectations. These findings provide evidence of a broad principle of infant attention across modalities and suggest that sound‐to‐sound transitional statistics heavily influence the allocation of auditory attention in human infants.     

Embracing Social Sustainability in Design Education: A Reflection on a Case Study in Haiti

Sustainable design issues are complex and multi-faceted and need integration in the education of young designers. Current research recommends a holistic view based on problem-solving and inter-disciplinary work, yet few design educators have brought these ideas to their full consequence. Sustainability education for designers is still often rooted in environmental issues, providing incomplete understanding of the broader relationships at hand. The article reflects on a case study of a student-initiated multi-disciplinary design project in Haiti. This reflection allows for discussing a number of issues related to establishing an educational agenda for incorporating social sustainability in design education, including recommendations for how to address motivation, expected learning outcomes, and feedback and guidance.     

Relations among home literacy environment,child characteristics and print knowledge for preschool children with language impairment

To contribute to the modest body of work examining the home literacy environment (HLE) and emergent literacy outcomes for children with disabilities, this study addressed two aims: (a) to determine the unique contributions of the HLE on print knowledge of preschool children with language impairment and (b) to identify whether specific child characteristics (oral language ability, print interest) moderated these relations. The sample consisted of 119 preschool children with language impairment. HLE was conceptualised as frequency of storybook reading and literacy teaching during book reading. Frequency of storybook reading was a unique predictor of print knowledge, which is consistent with research on children with typical language. Literacy teaching did not predict print knowledge, which diverges from research on children with typical language. No interactions between the HLE and child characteristics were significant, but language ability and print interest play a role in understanding individual differences in literacy development.     

Validity of the children's orientation to book reading rating scale

The present study investigates the validity of a 4‐point rating scale used to measure the level of preschool children's orientation to literacy during shared book reading. Validity was explored by (a) comparing the children's level of literacy orientation as measured with the Children's Orientation to Book Reading Rating Scale (COB) with a teacher's rating of a child's level of attention and effortful control on the Children's Behaviour Questionnaire (CBQ), and (b) computing the predictive validity of a child's COB rating with overall levels of emergent literacy at the end of the preschool school year. This study involved 46 preschool children from low‐income backgrounds; children's literacy orientation was rated during a group teacher‐led book reading. Children's ratings of literacy orientation during shared book reading using the global 4‐point COB scale were significantly correlated with teacher ratings of a child's attention and effortful control as measured on the CBQ. Hierarchical regression results indicated children's literacy orientation significantly predicted children's end‐of‐year alphabet knowledge and overall emergent reading skills above and beyond the variance contributed by children's language skills and family income. The validity of a global rating for indexing children's level of literacy orientation was supported. Educational implications and recommendations for the COB as a component of early literacy assessment are discussed.
