Usefulness of the COnUT index upon hospital admission as a potential prognostic indicator of COVID-19 health outcomes

Background:In-hospital mortality in patients with coronavirus disease 2019(COVID-19)is *** prognostic indices are needed to identify patients at high-risk of COVID-19 health *** aimed to determine the usefulness of the COntrolling nUTritional status(COnUT)index as a potential prognostic indicator of mortality in COVID-19 patients upon hospital ***:Our study design is of a retrospective observational study in a large cohort of COVID-19 *** addition to descriptive statistics,a Kaplan-Meier mortality analysis and a Cox regression were performed,as well as receiver operating curve(ROC).Results:From February 5,2020 to January 21,2021,there was a total of 2969 admissions for COVID-19 at our hospital,corresponding to 2844 ***,baseline(within 4 days of admission)COnUT index could be scored for 1627(57.2%)***’age was 67.3±16.5 years and 44.9%were *** COnUT severity distribution was:194(11.9%)normal(0-1);769(47.2%)light(2-4);585(35.9%)moderate(5-8);and 79(4.9%)severe(9-12).Mortality of 30 days after admission was 3.1%in patients with normal risk COnUT,9.0%light,22.7%moderate,and 40.5%in those with severe COnUT(Pn increased risk of death associated with a greater baseline COnUT stage was sustained in a multivariable Cox regression model(Pn increasing baseline COnUT stage was associated with a longer duration of admission,a greater requirement for the use of non-invasive and invasive mechanical ventilation,and other clinical outcomes(all PnUT for mortality had an area under the curve(AUC)and 95%confidence interval of 0.711(0.676-0746).Conclusion:The COnUT index upon admission is potentially a reliable and independent prognostic indicator of mortality and length of hospitalization in COVID-19 patients.

现在有关膳食对机体影响的代谢组学研究仅仅是研究膳食对血样和尿样的影响,而忽略了其他生物样本,例如盲肠内容物,就等于遗漏了消化系统的作用和忽略了肠道微生物菌群在代谢中的重要作用和其在生物利用率方面的影响。许多研究已经证明多组织样本代谢组学在评估营养物质在机体内的代谢影响方面的重要性。然而这些研究都是以核磁共振技术为分析手段的,由于核磁共振技术的低灵敏度,限制了可检测代谢产物的数量。
