The answers to these questions depend on the gestational age of the infant. We have focused on preterm infants <28 weeks of gestation as they are the most vulnerable and may have the maximum benefit of appropriate treatment. Therefore, we performed a sub-group analysis for data available from the published trials in infants less than 28 weeks who received less/minimal invasive surfactant administration/therapy [LISA/MIST] versus intubation-surfactant-extubation (INSURE). The need for mechanical ventilation (MV) was significantly reduced by 28 % (RR:0.72, 95%CI:0.64-0.80, n = 548 infants) after LISA/MIST. The incidence of bronchopulmonary dysplasia (BPD) was significantly decreased by 30 % (RR:0.70, 95%CI:0.66-0.75, n = 6528 infants) after LISA/MIST.

Quantifying the disease burden in monetary terms is crucial for resource allocation and public health prioritization, yet data on the economic impact of NE-related neonatal mortality and prevention is limited. This study estimates the country-specific disease burden and economic impacts of NE for the ten countries with the highest death tolls in 2019. Using data from the Global Burden of Disease (GBD) Collaborative Network, we analyzed NE-specific mortality trends and calculated years of life lost (YLLs) based on life expectancy, with and without age weighting and discounting. Economic losses were evaluated using the value per statistical life (VSL) and value per statistical life year (VSLY) methodologies, with sensitivity analyses incorporating variable discount rates. In 2019, the ten countries with the highest NE burden was estimated at 138,763 neonatal deaths. YLLs ranged from 4.5 million with discounting to 9.8 million without. While nine of these countries reduced overall neonatal mortality from 2010 to 2019, six saw rising NE-specific mortality. Economic losses were estimated at $80 billion using the VSL method and between $72 billion and $163 billion using VSLY. Despite overall progress in reducing neonatal mortality, targeted funded strategies are needed to address NE in LAMI countries. Burden of NE could be reduced with improved strategic access to quality antenatal care and effective peripartum practices through efficient and enhanced resource allocation.</p>","PeriodicalId":49547,"journal":{"name":"Seminars in Fetal & Neonatal Medicine","volume":" ","pages":"101560"},"PeriodicalIF":2.9,"publicationDate":"2024-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142631209","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Survival rates for extremely preterm infants have improved significantly, ranging from 0 to 37 % at 22 weeks to 31-78 % at 24 weeks. However, outcomes vary widely based on factors such as healthcare access and socioeconomic conditions. We propose using \"preterm birth between 20 and 25 weeks\" instead of \"periviability\" for clarity in clinical protocols and parental counseling. Ethical considerations, including potential overtreatment and parental autonomy, are addressed through clear guidelines. While challenges exist in implementing this approach, particularly in smaller or rural hospitals, solutions such as strengthening regional networks and telemedicine can address these issues.
