Baudelocque recommended obtaining infant milk fresh from the cow because it decomposes in the summer heat. In the cities, summer diarrhea caused a third of total infant mortality. Physicians debated whether heat acted directly on the infant or spoiled the food. The discovery of microorganisms in the 1860s revolutionized medical understanding.

Using a post hoc analysis, we summarized the ineligible studies that evaluated patients with severe BPD or BPD-PH who received iNO therapy. Although some studies included in the narrative review indicated a decreased pulmonary arterial pressure in patients with severe BPD or BPD-PH at the initiation of iNO therapy, none included a comparator group.</p><p><strong>Conclusion: </strong>Despite the use of iNO in patients with severe BPD and BPD-PH, no published studies compared the outcomes among patients with BPD treated with versus without iNO. Although some studies without comparator groups reported the effectiveness of iNO in patients with severe BPD and BPD-PH, our results suggest that iNO therapy should be initiated with caution and careful consideration of the target population.</p>","PeriodicalId":94152,"journal":{"name":"Neonatology","volume":" ","pages":"467-476"},"PeriodicalIF":3.0,"publicationDate":"2025-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC12324802/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143545482","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
