The sensitivity of both parameters was 81.8 %. Combination of these two methods yielded a higher predictive value (62.2%) but decreased the sensitivity (69.7%). The patterns of phospholipids reflect lung maturity, but also serum protein levels indicating overall maturity and the osmotic powers of microcirculation may be of diagnostic value in featuring developing RDS.<\/jats:p>","DOI":"10.1159\/000299100","type":"journal-article","created":{"date-parts":[[2010,3,16]],"date-time":"2010-03-16T04:07:18Z","timestamp":1268712438000},"page":"317-321","source":"Crossref","is-referenced-by-count":0,"title":["Gastric Aspirate L\/S Ratio and Umbilical Cord Blood Total Protein as Predictors in RDS"],"prefix":"10.1159","author":[{"given":"Henrik","family":"Ekblad","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Pentti","family":"Kero","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ilkka","family":"V\u00e4lim\u00e4ki","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"127","published-online":{"date-parts":[[2010,3,16]]},"container-title":["Gynecologic and Obstetric Investigation"],"original-title":[],"language":"en","link":[{"URL":"https:\/\/karger.com\/article-pdf\/doi\/10.1159\/000299100","content-type":"unspecified","content-version":"vor","intended-application":"similarity-checking"}],"deposited":{"date-parts":[[2026,5,1]],"date-time":"2026-05-01T06:37:37Z","timestamp":1777617457000},"score":1,"resource":{"primary":{"URL":"https:\/\/karger.com\/article\/doi\/10.1159\/000299100"}},"subtitle":[],"short-title":[],"issued":{"date-parts":[[2010,3,16]]},"references-count":0,"URL":"https:\/\/doi.org\/10.1159\/000299100","archive":["Portico"],"relation":{},"ISSN":["0378-7346","1423-002X"],"issn-type":[{"value":"0378-7346","type":"print"},{"value":"1423-002X","type":"electronic"}],"subject":[],"published":{"date-parts":[[2010,3,16]]}}}
