No significant differences were found between the groups in admission to the neonatal intensive care unit, stay at the neonatal intensive care unit, need for a mechanical ventilator, respiratory distress syndrome or neonatal sepsis. &lt;i&gt;Conclusion:&lt;\/i&gt; The treatment of threatened preterm birth with tocolytics combined with intravaginal micronized natural progesterone significantly prolonged pregnancy and increased birth weight. However, an improvement in adverse perinatal outcomes was not observed.<\/jats:p>","DOI":"10.1159\/000328719","type":"journal-article","created":{"date-parts":[[2011,11,11]],"date-time":"2011-11-11T07:56:04Z","timestamp":1320998164000},"page":"269-273","source":"Crossref","is-referenced-by-count":36,"title":["Effect of Progesterone as a Tocolytic and in Maintenance Therapy during Preterm Labor"],"prefix":"10.1159","volume":"72","author":[{"given":"I.","family":"Arikan","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"A.","family":"Barut","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"M.","family":"Harma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"I.M.","family":"Harma","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2011,11,11]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2F0028-2243%2891%2990118-5"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1002%2Fuog.5159"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1067%2Fmob.2003.41"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1056%2FNEJMoa035140"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1056%2FNEJM199602293340904"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1002%2Fuog.2773"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1097%2FGCO.0b013e3280895dd3"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1097%2F01.AOG.0000258276.64005.ce"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajog.2007.01.002"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.pcl.2009.03.006"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajog.2008.12.035"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1479-828X.2007.00803.x"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajog.2006.09.009"}],"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/328719","content-type":"unspecified","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/328719","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/328719","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T19:23:38Z","timestamp":1745436218000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000328719"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2011]]},"references-count":13,"journal-issue":{"issue":"4","published-online":{"date-parts":[[2011,12,1]]},"published-print":{"date-parts":[[2011,12,6]]}},"URL":"https:\/\/doi.org\/10.1159\/000328719","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2011]]}}}
