Cochrane is a British charity formed to organise medical research findings so as to facilitate evidence-based choices about health interventions faced by health professionals, patients, and policy makers. Cochrane includes 53 review groups that are based at research institutions worldwide. Cochrane has approximately 30,000 volunteer experts from around the world.
MEDLINE is a bibliographic database of life sciences and biomedical information. It includes bibliographic information for articles from academic journals covering medicine, nursing, pharmacy, dentistry, veterinary medicine, and health care. MEDLINE also covers much of the literature in biology and biochemistry, as well as fields such as molecular evolution.
Orthomolecular medicine, a form of alternative medicine, aims to maintain human health through nutritional supplementation. The concept builds on the idea of an optimum nutritional environment in the body and suggests that diseases reflect deficiencies in this environment. Treatment for disease, according to this view, involves attempts to correct "imbalances or deficiencies based on individual biochemistry" by use of substances such as vitamins, minerals, amino acids, trace elements and fatty acids. The notions behind orthomolecular medicine are not supported by sound medical evidence and the therapy is not effective; even the validity of calling the orthomolecular approach a form of medicine has been questioned since the 1970s.
PubMed is a free search engine accessing primarily the MEDLINE database of references and abstracts on life sciences and biomedical topics. The United States National Library of Medicine (NLM) at the National Institutes of Health maintains the database as part of the Entrez system of information retrieval.
MedlinePlus is an online information service produced by the United States National Library of Medicine. The service provides curated consumer health information in English and Spanish. The site brings together information from the National Library of Medicine (NLM), the National Institutes of Health (NIH), other U.S. government agencies, and health-related organizations. There is also a site optimized for display on mobile devices, in both English and Spanish. In 2015, about 400 million people from around the world used MedlinePlus. The service is funded by the NLM and is free to users.
Medical Subject Headings (MeSH) is a comprehensive controlled vocabulary for the purpose of indexing journal articles and books in the life sciences; it serves as a thesaurus that facilitates searching. Created and updated by the United States National Library of Medicine (NLM), it is used by the MEDLINE/PubMed article database and by NLM's catalog of book holdings. MeSH is also used by ClinicalTrials.gov registry to classify which diseases are studied by trials registered in ClinicalTrials.
A health or medical library is designed to assist physicians, health professionals, students, patients, consumers, medical researchers, and information specialists in finding health and scientific information to improve, update, assess, or evaluate health care. Medical libraries are typically found in hospitals, medical schools, private industry, and in medical or health associations. A typical health or medical library has access to MEDLINE, a range of electronic resources, print and digital journal collections, and print reference books. The influence of open access (OA) and free searching via Google and PubMed has a major impact on the way medical libraries operate.
Medical education is education related to the practice of being a medical practitioner; either the initial training to become a physician, or additional training thereafter.
PubMed Central (PMC) is a free digital repository that archives publicly accessible full-text scholarly articles that have been published within the biomedical and life sciences journal literature. As one of the major research databases within the suite of resources that have been developed by the National Center for Biotechnology Information (NCBI), PubMed Central is much more than just a document repository. Submissions into PMC undergo an indexing and formatting procedure which results in enhanced metadata, medical ontology, and unique identifiers which all enrich the XML structured data for each article on deposit. Content within PMC can easily be interlinked to many other NCBI databases and accessed via Entrez search and retrieval systems, further enhancing the public's ability to freely discover, read and build upon this portfolio of biomedical knowledge.
Systematic reviews are a type of literature review that uses systematic methods to collect secondary data, critically appraise research studies, and synthesize findings qualitatively or quantitatively. Systematic reviews formulate research questions that are broad or narrow in scope, and identify and synthesize studies that directly relate to the systematic review question. They are designed to provide a complete, exhaustive summary of current evidence relevant to a research question. Systematic reviews of randomized controlled trials are key to the practice of evidence-based medicine, and a review of existing studies is often quicker and cheaper than embarking on a new study.
Megavitamin therapy is the use of large doses of vitamins, often many times greater than the recommended dietary allowance (RDA) in the attempt to prevent or treat diseases. Megavitamin therapy is typically used in alternative medicine by practitioners who call their approach orthomolecular medicine. Vitamins are useful in preventing and treating illnesses specifically associated with dietary vitamin shortfalls, but the conclusions of medical research are that the broad claims of disease treatment by advocates of megavitamin therapy are unsubstantiated by the available evidence. It is generally accepted that doses of any vitamin greatly in excess of nutritional requirements will result either in toxicity or in the excess simply being metabolised; thus evidence in favour of vitamin supplementation supports only doses in the normal range. Critics have described some aspects of orthomolecular medicine as food faddism or even quackery. Research on nutrient supplementation in general suggests that some nutritional supplements might be beneficial, and that others might be harmful; several specific nutritional therapies are associated with an increased likelihood of the condition they are meant to prevent.
National Comprehensive Cancer Network (NCCN) is an alliance of 28 cancer centers in the United States, most of which are designated by the National Cancer Institute as comprehensive cancer centers. It is a non-profit organization with offices in Plymouth Meeting, Pennsylvania. Timothy J. Eberlein, director of the Alvin J. Siteman Cancer Center, is chairman of the NCCN Board of Directors. It publishes the peer-reviewed medical journal Journal of the National Comprehensive Cancer Network.
SafetyLit is a bibliographic database and online update of recently published scholarly research of relevance to those interested in the broad field of injury prevention and safety promotion. Initiated in 1995, SafetyLit is a project of the SafetyLit Foundation in cooperation with the San Diego State University College of Health & Human Services and the World Health Organization - Department of Violence and Injury Prevention.
In medicine, levels of evidence (LoE) are arranged in a ranking system used in evidence-based practices to describe the strength of the results measured in a clinical trial or research study. The design of the study and the endpoints measured affect the strength of the evidence.
The UNISIST model of information dissemination was proposed in 1971 by the United Nations. UNISIST is a model of the social system of communication, which consists of knowledge producers, intermediaries, and users. These groups of people are different kinds of professionals. The social system also contains institutes such as research institutes, publishers, and libraries. The actors and institutions perform information services such as writing, publishing, storing and retrieving documents and information. The actors are communicating in both formal and informal ways and they are producing different kinds of documents such as journal articles, books, book reviews, proceedings, bibliographies and catalogues, dictionaries, handbooks, encyclopedias and review articles.
The Journal of Alternative and Complementary Medicine is a monthly peer-reviewed medical journal covering alternative medicine published by Mary Ann Liebert. It was established in 1995 and is the official journal of the Society for Acupuncture Research. The editor-in-chief is John Weeks, who succeeded the founding editor, Kim A. Jobst.
Readily visible alterations of the skin surface have been recognized since the dawn of history, with some being treated, and some not. One of the earliest known sources documenting skin ailments is the Ebers Papyrus, a medical document from ancient Egypt dating to around 1500 BC. It describes various skin diseases, including ulcers, rashes, and tumors, and prescribes surgery and ointments to treat the ailments.
Chronic fatigue syndrome (CFS), also referred to as myalgic encephalomyelitis (ME), is a medical condition characterized by long-term fatigue and other persistent symptoms that limit a person's ability to carry out ordinary daily activities.
The NIH Public Access Policy is an open access mandate, drafted in 2004 and mandated in 2008, requiring that research papers describing research funded by the National Institutes of Health must be available to the public free through PubMed Central within 12 months of publication. PubMed Central is the self-archiving repository in which authors or their publishers deposit their publications. Copyright is retained by the usual holders, but authors may submit papers with one of the Creative Commons licenses.
