NIH Request for Information (RFI) on Processes for database of Genotypes and Phenotypes Data Submission, Access, and Management

The National Institutes of Health has just issued a Request for Information (RFI) seeking public comment on the data submission and access processes for the NIH National Center for Biotechnology (NCBI) database of Genotypes and Phenotypes (dbGaP). The RFI also seeks comment on the management of data in dbGaP in order to consider options to improve and streamline these processes and to maximize the use and utility of dbGaP. The complete RFI, as well as instructions on how to comment, are available on the NIH website. Electronic responses will be accepted through April 7, 2017. NIH will consider all public comments before taking next steps. No proprietary, classified, confidential, or sensitive information should be included in responses. Comments received, including any personal information, will be posted without change after the close of the comment period to the NIH Genomic Data Sharing website.

Additional information about the importance of this RFI is included in a new Under the Poliscope blog posting, published by Dr. Carrie D. Wolinetz. For more information or additional questions, please contact the NIH Office of Science Policy.

National Library of Medicine’s TOXMAP Resource Now Includes TRI 2015 Data

MedlinePlus Reaches Major Milestone: Launch of Its 1000th Health Topic Page!

A major milestone was recently reached as MedlinePlus.gov launched its 1,000th health topic page about “Eye Care.” Created and maintained by the National Library of Medicine, MedlinePlus is the National Institutes of Health’s website providing trusted health information to the public. The winner of multiple awards and a consistent top scorer among federal websites, MedlinePlus debuted in 1998 with 22 health topic pages, which bring together information on a particular disease, condition, or wellness issue. Each health topic page provides a description of the condition or issue and directs users to vetted information from the NIH and other trusted sources. All content on MedlinePlus is reviewed and must meet strict quality guidelines.

MedlinePlus has steadily added new topics to respond to the growing needs of the public for reliable, up-to-date health information. The demand for additional health topics grew with the 2010 launch of MedlinePlus Connect, a service that links Electronic Health Records and other Health IT systems to targeted information from MedlinePlus. Today, over a million people visit MedlinePlus daily and benefit from the health topic pages, a medical encyclopedia, health news, surgery videos, a medical dictionary and much more. A Spanish language version of the site, MedlinePlus en español, premiered in 2002.

NLM Resources for February 2017 National Children’s Dental Health Month

The American Dental Association named February 2017 as National Children’s Dental Health Month. The National Library of Medicine has multilingual information about children’s dental health available for free online:

  • Check MedlinePlus for a collection of reliable links related to Child Dental Health, and use the Medical Encyclopedia on MedlinePlus to find instructions on brushing your child’s teeth and preventing tooth decay in early childhood. Various informational handouts in seven languages about child dental health can be downloaded on MedlinePlus.
  • Browse HealthReach for topics like dental care and oral hygiene to view and download patient information in over a dozen languages, including audio and video options for some records. For instance, the brochure Healthy Teeth, Health Kids is available in 13 languages, with audio downloads in eight languages. Use the split-screen view on HealthReach to view the document in English and a second language simultaneously.

Coming Soon: Updated Algorithm for PubMed Best Match Sort Order

An enhanced relevance algorithm for the “Best Match” sort order is coming to PubMed. The new algorithm incorporates machine learning to re-rank the top articles returned for improved relevance. The standard PubMed Best Match sort is based on a weighted term frequency algorithm. This approach calculates the frequency with which terms appear in PubMed records. Those frequencies are then applied in a weighted fashion to return a ranked list of PubMed citations that match your query terms. The new relevance algorithm includes machine learning to re-rank the top articles returned. This algorithm combines over 150 signals that are helpful for finding best matching results. Most of these signals are computed from the number of matches between the search terms and the PubMed record, while others are either specific to a record (e.g., publication type; publication year) or specific to a search (e.g., search length). The new ranking model was built on relevance data obtained from anonymous PubMed search logs that were aggregated over an extended period of time.

Because the “Best Match” results are calculated using a new machine learning environment, there might be a slight change in total search results when sorting by “Best Match.” Users who sort by “Best Match” are typically clicking through citations on the first page of retrieval; therefore, it is important for NLM to continue to incorporate new tools to improve this ranking. The new machine learning system achieves significant improvement in retrieval performance over the weighted term frequency algorithm alone. Additionally, the “Search details” portlet will be replaced with “Best match search information” that will display translations to MeSH, etc., and additional synonyms under the “See more…” link. The Search button will not be available for the new portlet used for “Best Match” results. To use “Best Match” as the default sort order for PubMed results, change your preferences in My NCBI.

Michael Phelps on the cover of NIH MedlinePlus the Magazine

The Winter 2017 issue of NIH MedlinePlus the Magazine highlights health topics including depression, prostate enlargement, breast cancer, pain management, and menopause.
