Predictive efficacy was analyzed in women at high risk for PTD and compared with cervical length (CL) <20 mm and fetal fibronectin (fFN) in cervicovaginal secretions. <i>Methods:<\/i> Case notes were reviewed for 108 subjects with gestation of 22\u201333 weeks who had been admitted to hospital with threatened PTD. The uterine cervix was observed by vaginal sonography and fFN was sampled on admission. Relationships between findings and outcome of PTD at <34 weeks\u2019 gestation were analyzed. <i>Results:<\/i> Delivery at <34 weeks\u2019 gestation occurred in 14.8% of patients. Absent CGA (68.8%), short CL (75.0%), short CL without CGA (62.5%) and positive fFN (62.5%) were more frequent in these patients than in patients undelivered at <34 weeks\u2019 gestation (p < 0.05). Logistic regression analysis identified positive fFN and short CL with absent CGA as independent predictors for PTD (p < 0.0001). The mean interval from admission to delivery was 2.9 weeks in cases with fFN and both sonographic findings, compared to 9.3 weeks in cases with fFN but both sonographic finding (p = 0.0005). <i>Conclusion:<\/i> Short CL with absent CGA represents an independent predictor for PTD, as does fFN.<\/jats:p>","DOI":"10.1159\/000209394","type":"journal-article","created":{"date-parts":[[2009,3,25]],"date-time":"2009-03-25T14:41:06Z","timestamp":1237992066000},"page":"1-8","source":"Crossref","is-referenced-by-count":20,"title":["Significance of Cervical Gland Area in Predicting Preterm Birth for Patients with Threatened Preterm Delivery: Comparison with Cervical Length and Fetal Fibronectin"],"prefix":"10.1159","volume":"68","author":[{"given":"Hirobumi","family":"Asakura","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Takehiko","family":"Fukami","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ryuhei","family":"Kurashina","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Naoko","family":"Tateyama","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Daisuke","family":"Doi","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Toshiyuki","family":"Takeshita","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"127","published-online":{"date-parts":[[2009,3,25]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","DOI":"10.1016%2FS0140-6736%2808%2960074-4"},{"key":"ref2","doi-asserted-by":"publisher","DOI":"10.1016%2FS0002-9378%2896%2970225-9"},{"key":"ref3","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ijgo.2006.03.022"},{"key":"ref4","doi-asserted-by":"publisher","DOI":"10.1056%2FNEJM199109053251001"},{"key":"ref5","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajog.2007.07.017"},{"key":"ref6","doi-asserted-by":"publisher","DOI":"10.1056%2FNEJM199602293340904"},{"key":"ref7","doi-asserted-by":"publisher","DOI":"10.1002%2Fuog.202"},{"key":"ref8","doi-asserted-by":"publisher","DOI":"10.1067%2Fmob.2000.104212"},{"key":"ref9","doi-asserted-by":"publisher","DOI":"10.1097%2FGCO.0b013e3280895dd3"},{"key":"ref10","doi-asserted-by":"publisher","DOI":"10.1515%2FJPM.1999.001"},{"key":"ref11","doi-asserted-by":"publisher","DOI":"10.1016%2FS0002-9378%2899%2970612-5"},{"key":"ref12","doi-asserted-by":"publisher","DOI":"10.1272%2Fjnms.70.135"},{"key":"ref13","doi-asserted-by":"publisher","DOI":"10.1046%2Fj.1469-0705.1998.12050328.x"},{"key":"ref14","doi-asserted-by":"publisher","DOI":"10.1159%2F000058366"},{"key":"ref15","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ultrasmedbio.2005.12.010"},{"key":"ref16","doi-asserted-by":"publisher","DOI":"10.1016%2FS0002-9378%2896%2970020-0"},{"key":"ref17","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajog.2004.06.054"},{"key":"ref18","doi-asserted-by":"publisher","DOI":"10.1016%2Fj.ajog.2007.04.021"},{"key":"ref19","doi-asserted-by":"publisher","DOI":"10.1111%2Fj.1471-0528.2007.01515.x"}],"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/209394","content-type":"application\/pdf","content-version":"vor","intended-application":"text-mining"},{"URL":"https:\/\/www.karger.com\/Article\/Pdf\/209394","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2025,4,23]],"date-time":"2025-04-23T22:41:06Z","timestamp":1745448066000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000209394"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2009]]},"references-count":19,"journal-issue":{"issue":"1","published-online":{"date-parts":[[2009,7,1]]}},"URL":"https:\/\/doi.org\/10.1159\/000209394","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2009]]}}}
