Research Overview<\/p>\n<div class=\"TextBlock\">\n<p>Worldwide, approximately 4.5 million people die of traumatic injury every year. Many of these patients die from blood loss.<\/p>\n<p>Early treatment with a drug called tranexamic acid stops excessive bleeding by reducing the body\u2019s ability to break down blood clots. However, tranexamic acid can cause unnecessary drug side effects in patients who do not need it, so it is necessary to select truly effective target patients based on objective criteria.<\/p>\n<p>Now, in a study published in <em>Critical Care<\/em>, researchers from Osaka University have addressed this treatment challenge by identifying subgroups of trauma patients who are more likely to survive if treated with tranexamic acid. The team found these subgroups by examining trauma patients who shared similar traits (also known as phenotypes).<\/p>\n<p>\u201cWe identified eight different trauma phenotypes, and then we evaluated the benefits of tranexamic acid treatment based on these phenotypes,\u201d explains lead author Jotaro Tachino. \u201cWe found subgroups of patients with significantly lower in-hospital mortality when they received tranexamic acid. We also found subgroups of patients who received no benefit from treatment.\u201d<\/p>\n<p>The team used machine learning to help categorize trauma patients into these subgroups. Using this technique, researchers processed information from over 50,000 patients in the Japan Trauma Data Bank and then analyzed patterns associated with trauma, treatment, and survival.<\/p>\n<p>The team found an association between trauma phenotypes and in-hospital mortality, indicating that treatment with TXA could potentially influence this relationship.<\/p>\n<p>The reserchers say \u201cTrauma patients are a heterogeneous population with injuries that vary greatly in type and severity. This makes it difficult to predict how effective a treatment will be in an individual patient\u201d. \u201cWe hope our results will help individual trauma patients receive more personalized care as well as improve the quality of care for all trauma patients.\u201d<\/p>\n<p>Given the high death toll from traumatic injury, strategies that improve survival are essential for patients and their families. This research is a key step in optimizing tranexamic acid use in trauma patients.<\/p>\n<\/div>\n<p>###<\/p>\n<p>The article, \u201cAssociation between tranexamic acid administration and mortality based on the trauma phenotype: a retrospective analysis of a nationwide trauma registry in Japan,\u201d was published in <em>Critical Care <\/em>at DOI: <a href=\"https:\/\/doi.org\/10.1186\/s13054-024-04871-w\">https:\/\/doi.org\/10.1186\/s13054-024-04871-w<\/a>.<\/p>\n<p><strong>Summary:<\/strong> Researchers from Osaka University used machine learning to identify subgroups of trauma patients who are more likely to survive their injuries if treated with tranexamic acid. This treatment controls bleeding and thereby prevents death from hemorrhage. The team also identified subgroups of trauma patients who do not benefit from tranexamic acid. These findings should help guide treatment decisions after traumatic injury and provide trauma patients with more personalized care.<\/p>\n<p><strong>Tweet <\/strong>: Research out of @osaka_univ_e uses machine learning to identify which #trauma patients benefit from #tranexamic acid treatment<\/p>\n<p><strong>Primary Keyword<\/strong>: Health and medicine<br \/><strong>Additional Keywords<\/strong>: Physical trauma, bleeding, drug therapy, mortality rates, risk reduction, hospitals, emergency medicine, machine learning<\/p>\n<p><strong>Method of Research<\/strong>: Observational study<\/p>\n<p><strong>Subject of Research<\/strong>: People<\/p>\n<div class=\"TextBlock\">\n<p>Title: \u201cAssociation between tranexamic acid administration and mortality based on the trauma phenotype: a retrospective analysis of a nationwide trauma registry in Japan\u201d<\/p>\n<\/div>\n<p>Journal: <em>Critical Care<\/em><em><br \/><\/em>Authors: Jotaro Tachino, Shigeto Seno, Hisatake Matsumoto, Tetsuhisa Kitamura, Atsushi Hirayama, Shunichiro Nakao, Yusuke Katayama, Hiroshi Ogura, Jun Oda.<br \/>DOI: <a href=\"https:\/\/doi.org\/10.1186\/s13054-024-04871-w\">10.1186\/s13054-024-04871-w<\/a><\/p>\n<p>Japan Society for the Promotion of Science (JSPS)<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Text in Japanese Critical Care Researchers from Osaka University use machine learning to identify patients mor [&hellip;]<\/p>\n","protected":false},"author":1,"featured_media":8157,"parent":8108,"menu_order":40,"comment_status":"closed","ping_status":"closed","template":"","meta":{"footnotes":""},"_links":{"self":[{"href":"https:\/\/www.med.osaka-u.ac.jp\/eng\/wp-json\/wp\/v2\/pages\/8156"}],"collection":[{"href":"https:\/\/www.med.osaka-u.ac.jp\/eng\/wp-json\/wp\/v2\/pages"}],"about":[{"href":"https:\/\/www.med.osaka-u.ac.jp\/eng\/wp-json\/wp\/v2\/types\/page"}],"author":[{"embeddable":true,"href":"https:\/\/www.med.osaka-u.ac.jp\/eng\/wp-json\/wp\/v2\/users\/1"}],"replies":[{"embeddable":true,"href":"https:\/\/www.med.osaka-u.ac.jp\/eng\/wp-json\/wp\/v2\/comments?post=8156"}],"version-history":[{"count":6,"href":"https:\/\/www.med.osaka-u.ac.jp\/eng\/wp-json\/wp\/v2\/pages\/8156\/revisions"}],"predecessor-version":[{"id":8221,"href":"https:\/\/www.med.osaka-u.ac.jp\/eng\/wp-json\/wp\/v2\/pages\/8156\/revisions\/8221"}],"up":[{"embeddable":true,"href":"https:\/\/www.med.osaka-u.ac.jp\/eng\/wp-json\/wp\/v2\/pages\/8108"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.med.osaka-u.ac.jp\/eng\/wp-json\/wp\/v2\/media\/8157"}],"wp:attachment":[{"href":"https:\/\/www.med.osaka-u.ac.jp\/eng\/wp-json\/wp\/v2\/media?parent=8156"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
