Invasive fungal infection (IFI) is one of the common causes of healthcare-associated infections. Objectives To describe the prevalence and short-term outcomes of children with IFI, and to offer a basis for the efficient prevention and treatment of IFI. Methods A retrospective study was conducted in children under the age of 12 years over a two-year period. Participants were categorised according to pre-defined microbiology criteria into IFI if they had a positive culture from blood or other sterile sites. Data collected included demographics, invasive procedures, length of stay and mortality. Results One thousand and forty-two children were admitted during the study period. Of the total, 56.8% (n=592) were male. Median length of stay was 18 days (mean±SE 18.6±8.9). IFI was identified in 35 cases per 1 000 admissions, with 77.7% of these infants under the age of one year. The mean length of stay was 18.6 days compared with 7.5 days for children with bacterial infections. The in-hospital mortality for invasive fungal infection was 36% compared with 16% for all admissions. Findings confirmed that colonisation was more prevalent than IFI. Conclusion IFIs are common among infants, and these patients have a higher mortality rate and prolonged hospital stay. Therefore we recommend early diagnosis and timely treatment with high-performance antifungal drugs to improve the prognosis in children with IFI.","PeriodicalId":52847,"journal":{"name":"African Journal of Thoracic and Critical Care Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"44387050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Yet despite the global numbers of patients treated, guidance is not clear on the correct choice of modality or the timing of escalation of therapy for an individual patient. This narrative review assesses the available literature on the best use of different modalities of respiratory support for an individual patient, and discusses benefits and risks of each, coupled with practical advice to improve outcomes. On current data, in an ideal context, it appears that as disease severity worsens, conventional oxygen therapy is not sufficient alone. In more severe disease, i.e. PaO₂/FiO₂ ratios below approximately 200, helmet-CPAP (continuous positive airway pressure) (although not widely available) may be superior to high-flow nasal cannula (HFNC) therapy or facemask non-invasive ventilation (NIV)/CPAP, and that facemask NIV/CPAP may be superior to HFNC, but with noted important complications, including risk of pneumothoraces. In an ideal context, invasive mechanical ventilation should not be delayed where indicated and available. Vitally, the choice of respiratory support should not be prescriptive but contextualised to each setting, as supply and demand of resources vary markedly between institutions. Over time, institutions should develop clear policies to guide clinicians before demand exceeds supply, and should frequently review best practice as evidence matures.</p>","PeriodicalId":52847,"journal":{"name":"African Journal of Thoracic and Critical Care Medicine","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2022-09-16","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/39/63/AJTCCM-28-3-241.PMC9650135.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"40722397","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}
