Content and trends in medical informatics publications over the past two decades.
This study aims to identify subject content and trends in the medical informatics literature in order to shed light on the past, current, and future directions of diverse education and research activities. It found 73 core topics and 72 new topics of medical informatics within three relevant MeSH categories (informatics, techniques, and healthcare).

Translational morphosyntax: distribution of negation in clinical records and biomedical journal articles.
This paper describes the distribution of negation in two types of biomedical texts: scientific journal articles and progress notes. Two types of negation are examined: explicit negation at the syntactic level and affixal negation at the sub-word level. The data show that the distribution of negation is significantly different in the two document types.

Factors affecting willingness to share electronic health data among California consumers.
The objective of the study is to explore factors that affect consumers' willingness to share electronic health information for healthcare and research. It concluded that consumers' choices about electronically sharing health information are affected by their attitudes toward EHRs as well as beliefs about research benefit and individual control.

A system to build distributed multivariate models and manage disparate data sharing policies: implementation in the scalable national network for effectiveness research.
The authors’ objective was to implement infrastructure that supports the functionality of some existing research networks (e.g., cohort discovery, workflow management, and estimation of multivariate analytic models on centralized data) while adding additional important new features. They were able to implement massively parallel (map-reduce) computation methods and a new policy management system to enable each study initiated by network participants to define the ways in which data may be processed, managed, queried, and shared.

Beyond traditional advertisements: leveraging Facebook's social structures for research recruitment.
This study aimed to develop and assess the feasibility, benefits, and challenges of recruiting for research studies related to consumer health information technology (IT) by leveraging the social structures embedded in the social networking platform, Facebook. It demonstrated that leveraging the social structures of Facebook for health-related research was feasible for obtaining small samples appropriate for qualitative research but not for obtaining large samples needed for quantitative research.

Integration of NNN into EHRS: how are we doing?: IJNK virtual issue.
This commentary introduces a virtual edition of IJNK, hosted on the Journal’s website. It includes six articles published in the last 20 years that provide a snapshot of efforts to integrate one or more of the standardized terminologies, NANDA-I, NOC, NIC (NNN), into electronic health records (EHRs).
