RESUMEN
Neonatal critical illness score(NCIS) has been published for over 20 years in China and has played an active role in critical neonatal transport, illness severity assessment, and prognosis evaluation.However, there are still some limitations in the scoring system with the development of medical technology, such as failure to include crucial perinatal information, unable to quantify single indicators, difficulty in obtaining PaO 2 without oxygen inhalation, complex evaluation indicators, long evaluation time and data was difficult for scientific research, etc.Therefore, it is necessary to update and simplify it for the clinical treatment and scientific study of critically ill newborns.This review summarized NCIS application in China and compared it with foreign neonatal critical scores such as score for neonatal acute physiology, clinical risk index for babies, etc.Combined with the rising technology of artificial intelligence and deep learning in recent years, it was more straightforward and optimized to enhance its accuracy and applicability, which was aimed to play a more active role in the treatment of critical newborns and scientific research.
RESUMEN
Objective:To analyze the role of perfusion index(PI)in assessing the severity of neonatal illnesses.Methods:A total of 502 newborns admitted to the Department of Neonatology within 24 hours of birth at Xinxiang Central Hospital from October 2018 to July 2019 were recruited.Neonatal critical illness score(NCIS)was graded within 24 hours of admission, and newborns were categorized into non-critical(NCIS>90 scores), critical(NCIS 70-90 scores)and extremely critical(NCIS<70 scores). PI was monitored in all newborns within 24 hours of birth in a resting state.A total of 502 PIs were recorded, including 341 cases of non-critical, 110 cases of critical and 51 cases of extremely critical.Results:The medium PI [ M( P25, P75)] of newborns in non-critical, critical and extremely critical groups were 1.80(1.40, 2.60), 0.96(0.74, 1.43)and 0.65(0.41, 1.10), respectively.PI values in extremely critical group was significantly lower than those in critical group and non-critical group( P<0.05). The medium PI [ M( P25, P75)] of full-term newborns, moderate/late preterm newborns and extremely/very preterm newborns were 1.70(1.20, 2.70), 1.60(1.10, 2.30) and 1.35(0.80, 2.30), respectively.PI in full-term newborns was significantly higher than those in moderate/late preterm newborns and extremely/very preterm newborns( P<0.05). PI was moderately positively correlated with NCIS in newborns( r=0.791, P<0.01). The area under the receiver operating characteristic curve of NCIS predicted by PI value was 0.846, and the prediction sensitivity and specificity were 85.0% and 70.8% when PI was 0.56. Conclusion:PI is correlated with NCIS in newborns, which is able to reflect the severity of neonatal illnesses.A low PI indicates severe conditions of neonatal illnesses.
RESUMEN
Objective:To explore the effect of pediatric critical illness score (PCIS), pediatric risk of mortality Ⅲ score (PRISM Ⅲ), pediatric logistic organ dysfunction 2 (PELOD-2), pediatric sequential organ failure assessment (p-SOFA) score and Glasglow coma scale (GCS) in the prognosis evaluation of septic-associated encephalopathy (SAE).Methods:The data of children with SAE admitted to the Pediatric Intensive Care Unit (PICU), Guangdong Provincial People’s Hospital, Guangdong Academy of Medical Sciences from January 2010 to December 2020 were retrospectively analyzed. They were divided into the survival and death groups according to the clinical outcome on the 28th day after admission. The efficiency of PCIS, PRISM Ⅲ, PELOD-2, p-SOFA and GCS scores for predicting death were evaluated by the area under the ROC curve (AUC). The Hosmer-Lemeshow goodness-of-fit test assessed the calibration of each scoring system.Results:Up to 28 d after admission, 72 of 82 children with SAE survived and 10 died, with a mortality rate of 12.20%. Compared with the survival group, the death group had significantly lower GCS [7 (3, 12) vs. 12 (8, 14)] and PCIS scores [76 (64, 82) vs. 82 (78, 88)], and significantly higher PRISM Ⅲ [14 (12, 17) vs. 7 (3, 12)], PELOD-2 [8 (5, 13) vs. 4 (2, 7)] and p-SOFA scores [11 (5, 12) vs. 6 (3, 9)] ( P<0.05). The AUCs of PCIS, PRISM Ⅲ, PELOD-2, p-SOFA and GCS scores for predicting SAE prognosis were 0.773 ( P=0.012, AUC>0.7), 0.832 ( P=0.02, AUC>0.7), 0.767 ( P=0.014, AUC>0.7), 0.688 ( P=0.084, AUC<0.7), and 0.692 ( P=0.077,AUC<0.7), respectively. Hosmer-Lemeshow goodness-of-fit test showed that PCIS ( χ2=5.329, P=0.722) predicted the mortality and the actual mortality in the best fitting effect, while PRISM Ⅲ ( χ2=12.877, P=0.177), PELOD-2 ( χ2=8.487, P=0.205), p-SOFA ( χ2=9.048, P=0.338) and GCS ( χ2=3.780, P=0.848) had poor fitting effect. Conclusions:The PCIS, PRISM Ⅲ and PELOD-2 scores have good predictive ability assessing the prognosis of children with SAE, while the PCIS score can more accurately evaluate the fitting effect of SAE prognosis prediction.
RESUMEN
Objective:To compare the early and late predictive values of critical illness score (CIS) and procalcitonin (PCT) in septic patients with blood stream infection (BSI) induced by intra-abdominal infection (IAI), and to identify the value of PCT in etiological diagnosis.Methods:The clinical data of patients with at least one positive blood culture within 24 hours admission to the emergency department of China-Japan Friendship Hospital from January 2014 to December 2019 and with final diagnosis of IAI induced sepsis were enrolled. Sequential organ failure assessment (SOFA), mortality in emergency department sepsis (MEDS), Logistic organ dysfunction system (LODS), and acute physiology and chronic health evaluation Ⅱ (APACHEⅡ) scores were calculated based on the parameters on the day of admission. Differences in various indicators among different Gram-stained bacterial infections and among patients with different prognosis at 28 days or 60 days were compared. Receiver operator characteristic curve (ROC curve) was used to analyze the value of PCT in differential etiological diagnosis of IAI induced sepsis caused by single bacterial infection, and the predictive value of CIS and PCT on 28-day and 60-day death of septic patients with BSI induced by IAI.Results:A total of 221 septic patients with IAI caused by single bacterial infection were enrolled. The 28-day mortality was 19.9% (44/221), and the 60-day mortality was 25.8% (57/221). Mortality caused by Gram-positive (G +) bacterial infection of patients was significantly higher than that caused by Gram-negative (G -) bacterial infection (28 days: 34.6% vs. 11.4%, 60 days: 42.0% vs. 16.4%, both P < 0.01). Compared with patients with G + bacterial infection, the PCT value of patients with G - bacterial infection was higher [μg/L: 4.31 (0.71, 25.71) vs. 1.29 (0.32, 10.83), P < 0.05]. Compared with survival group, the values of CIS and PCT in death group were higher, either in 28 days or in 60 days [death group vs. survival group in 28 days: SOFA score was 6.0 (4.0, 10.0) vs. 3.0 (2.0, 5.0), MEDS score: 11 (9, 14) vs. 6 (6, 9), LODS score: 4.0 (2.0, 6.0) vs. 1.0 (0, 2.0), APACHEⅡ score: 17.0 (15.0, 24.0) vs. 12.0 (8.0, 15.0), PCT (μg/L): 3.48 (1.01, 26.70) vs. 2.45 (0.32, 15.65); death group vs. survival group in 60 days: SOFA score: 6.0 (4.0, 10.0) vs. 3.0 (2.0, 5.0), MEDS score: 9 (6, 14) vs. 6 (6, 9), LODS score: 4.0 (1.0, 5.0) vs. 1.0 (0, 2.0), APACHEⅡ score: 16.5 (12.0, 20.0) vs. 12.0 (8.0, 15.0), PCT (μg/L): 2.67 (0.98, 17.73) vs. 2.22 (0.31, 16.75); all P < 0.05]. ROC curve showed that: ① the area under ROC curve (AUC) of PCT in the diagnosis of IAI induced sepsis with single bacterial infection was 0.740 [95% confidence interval (95% CI) was 0.648-0.833]. When the optimal cut-off value of PCT was 1.82 μg/L, the sensitivity of diagnosis of G - bacterial infection was 74.0%, and the specificity was 68.2%. When PCT value was higher than 10.92 μg/L, the specificity of diagnosis of G - bacterial infection could reach 81.8%. ② In the prediction of 28-day and 60-day mortality for septic patients with BSI induced by IAI, the APACHEⅡ score achieved the highest AUC [28 days: 0.791 (95% CI was 0.680-0.902), 60 days: 0.748 (95% CI was 0.645-0.851)]. APACHEⅡ score higher than 14.5 could help to predict 28-day and 60-day mortality for IAI patients with negative predictive values of 94.9% and 88.5%. However, the predictive value of PCT for septic patients with BSI induced by IAI was relatively lower [28-day AUC: 0.610 (95% CI was 0.495-0.725), 60-day AUC: 0.558 (95% CI was 0.450-0.667)]. Conclusion:PCT is more reliable in the identification of pathogen type among IAI induced sepsis with BSI, while APACHEⅡ score may perform better in predicting early and late mortality.

Objective:To explore the value of body temperature, pediatric clinical illness score(PCIS), white blood cell count (WBC), plasma C-reactive protein (CRP), procalcitonin (PCT) and pro-adrenomedullin (pro-ADM) in predicting nosocomial infection in PICU.Methods:From June 2016 to March 2017, the critically ill children in PICU of Children′s Hospital of Fudan University were selected and divided into nosocomial infection group and non nosocomial infection group according to the diagnostic criteria of nosocomial infection.The body temperature, PCIS, WBC, CRP, PCT and pro-ADM were recorded at 4 hours (T1), (48±1) hours (T2), (120±1) hours (T3) and (192±1) hours (T4) after admission, and their predictive value of each index, which was the closest time point (Th) to nosocomial infection was analyzed.Receiver-operating characteristic (ROC) curves were performed to calculate the areas under the curves (AUC), sensitivity and specificity, and multivariate Logistic regression analysis was used to study the risk factors of nosocomial infection.Results:A total of 85 cases were included, including 27 cases in nosocomial infection group and 58 cases in non nosocomial infection group.There was no significant difference in age, weight, body temperature, WBC, PCT, pro-ADM, primary disease and invasive operation between two groups (all P>0.05). There were significant differences in gender, PCIS, CRP, intubation rate and central venous catheterization rate ( P<0.05), when patients were admitted to PICU.At Th, the differences of body temperature, PCIS, CRP, PCT and pro-ADM between two groups were statistically significant ( P<0.05), as well as the AUC were 0.787, 0.755, 0.709, 0.704 and 0.809, respectively, as well as the best cut-off values for predicting nosocomial infection were 38.0 ℃, 87 points, 14.5 mg/L, 0.28 ng/mL and 0.67 nmol/L, respectively.There was no significant difference regarding WBC between two groups ( P>0.05). PCIS may be an independent risk factor for nosocomial infection( OR=0.978, 95% CI 95.9-99.9, P<0.05). Conclusion:Pro-ADM has high sensitivity and specificity in predicting nosocomial infection, and PCIS is an independent risk factor for nosocomial infection.
RESUMEN
Neonatal critical illness score is a scoring system that assesses the severity of neonatal disease and predicts the risk of death.However, it also has an important reference value for the evaluation of neurological prognosis.Since various neonatal critical scores have different assessment contents, the evaluation performance of neurological prognosis is also different.Score for neonatal acute physiology, score for neonatal acute physiology, version-Ⅱ, score for neonatal acute physiology, perinatal extension, version-Ⅱ, nursery neurobiological risk score, et al, have good predictive value for long-term neurological prognosis.The predictive value of clinical risk index for babies, clinical risk index for babies and version-Ⅱ remains unproven.This article reviews the correlation between neonatal critical illness score and the neurological prognosis of very low birth weight infants(VLBWI), in order to provide references for the early identification and prognositic judgement of VLBWI nerve damage.

RESUMEN
Objective To study the changes in serum adiponectin level in children with severe sepsis,and to explore its clinical significance.Methods A prospective study was conducted,and 39 cases of critically ill children with severe sepsis and 47 cases of sepsis were enrolled into the Pediatric Intensive Care Unit(PICU),Children's Hospital of Nanjing Medical University from July 2012 to July 2014.Thirty cases of critically ill children without sepsis were enrolled as a control group.The plasma adiponectin,procalcitonin(PCT),and C-reactive protein(CRP)were determined with enzyme linked immunosorbent assay(ELISA)within 24 hours after PICU admission.The pediatric critical illness score(PCIS)was recorded.Results Among severe sepsis group,sepsis group and control group,there was no statistical significance in body temperature,heart rate,body mass index,PCIS,white blood cell count,platelet count,bilirubin,creatinine,pH value and activated partial thromboplastin time(APTT)(all P>0.05).Plasma adiponectin in the severe sepsis group[(0.102±0.041)mg/L] significantly decreased compared with that in the sepsis group[(0.125±0.046)mg/L] and the control group[(0.147±0.047)mg/L](F=8.456,P=0.000).The level of CRP in the severe sepsis group[(60.68±59.43)mg/L] significantly increased compared with that in the sepsis group[(52.76±26.67)mg/L] and the control group[(33.89±6.87)mg/L](F=17.416,P=0.000).There was a statistical significance in PCT level in the severe sepsis group,the sepsis group and the control group(x2=27.269,P=0.000).Further comparison showed that there was a significant difference in PCT level between the severe sepsis group and the sepsis group(Z=-4.679,P=0.000),which was also statistically significant between the severe sepsis group and the control group(Z=-4.244,P=0.000);there was no significant difference between the sepsis group and the control group(Z=-0.340,P=0.733).Negative correlation was found between plasma adiponectin and CRP(r=-0.219,P=0.042),PCT(r=-0.303,P=0.005).The correlation between plasma adiponectin and PCIS was positively correlated(r=0.332,P=0.002).Conclusions Plasma adiponectin decreased in severe sepsis children and was significantly associated with the severity of the disease.Detection of plasma adiponectin levels in children with sepsis has an important clinical significance in evaluating the severity of sepsis.Plasma adiponectin is negatively correlated with CRP and PCT,and plays a role in diagnosis of infection.
RESUMEN
Objective To explore the effect of thrombelastography in sepsis and septic shock with disseminated intravascular coagulation (DIC) condition in children.Methods Ninety-one cases of children admitted to the Pediatric Intensive Care Unit,Zhengzhou Children's Hospital between January 2013 and December 2016 were enrolled in this study.Fifty-eight cases of sepsis,17 cases of severe sepsis and 16 cases of septic shock (including 7 cases DIC and 9 cases non-DIC) were included in 91 cases of children.After admission,they were given conventional treatment according to their condition of illness,such as expansion of rehydration,applying vascular active drags,anti-infection,mechanical ventilation,maintaining internal environment,nutrition support,etc.Thrombelastography of all the patients were detected for 6 hours after admission.The test indexes included blood coagulation reaction time (R),blood clot formation time (K) and blood clot formation rate (alpha),maximum width (MA),coagulation index (CI),etc.And pediatric critical illness scores(PCIS) were also evaluated for 6 hours after admission.Results With the progression of sepsis severity,R value,K value increased dramatically (F =3.629,4.237,all P ＜ 0.05),alpha angle,MA value,CI value decreased (F =32.631,19.938,10.849,all P ＜ 0.05);R value,K value and PCIS scores showed a significant positive correlation (r =0.591,0.827,all P ＜ 0.05),alpha angle,MA value,CI and PCIS scores showed a significant negative correlation (r =-0.793,-0.827,-0.839,all P ＜ 0.05).R and K values in DIC group were significantly greater than the values of non-DIC group (t =4.381,2.613,all P ＜ 0.05),alpha angle was less than that of DIC group obviously (t =5.627,P ＜ 0.05).In DIC group MA and CI levels were significantly less than those of non-DIC group (t =5.416,2.951,all P ＜ 0.05).R value,K value,alpha Angle,MA,CI levels between the dead and surviving patients in the septic shock group had no significant difference (all P ＞ 0.05).Conclusions TEG has a great significance in evaluating severity of children with sepsis.It can also guide clinical assessment in children with septic shock DIC so as to give accurate effective intervention and improve the rescue success rate and the prognosis.

RESUMEN
Objective To establish a discriminant method based on clinical and laboratory data and common examinations for early predicting the severity of pediatric infection. Methods Consecutive hospitalized patients diag-nosed as septic shock were included who were admitted between June 2014 and May 2015 retrospectively. Gender (male - female ratio:1. 25∶ 1. 00)and age(1 month to 6 years old)were matched in all of 18 patients with septic shock,and 27 patients diagnosed as systemic inflammatory response syndrome(SIRS),sepsis and severe sepsis on ad-mission were included respectively in order of sequential admission number during the same period. Additional 36 gen-der - and age - matched children with common infection(non - SIRS)were enrolled as controls. The clinical and labo-ratory examination data of all the included patients were collected and then the pediatric critical illness scores(PCIS) were made according to the worst condition within 24 hours of hospitalization. The parameters correlated with the severi-ty of infection were evaluated by rank correlation and Logistic regression analysis. The discriminant models were estab-lished based on κth - nearest - neighbor analysis and evaluated with clinical diagnosis by interrater agreement test. Results Except for platelet count,the other indexes including PCIS,neutrophil count,C - reactive protein,procalcito-nin(PCT),international normalized ratio of prothrombin time,activated partial thromboplastin time,thrombin time,fi-brinogen,fibrin/ fibrinogen degradation product(FDP)and D - dimer(D - D)all had differences among groups with varying infection severity(all P ﹤ 0. 001). The Spearman's coefficient ρ of PCIS,PCT,D - D and FDP correlated to in-fection severity were - 0. 837,0. 680,0. 679 and 0. 648,respectively(all P ﹤ 0. 001). Multivariate cumulative odds Lo-gistic regression analysis showed PCIS,D - D and PCT were related to infection severity(all P ﹤ 0. 05). The total error rate of discriminant models based on 3 - index combination(Mahalanobis transformation,k = 2)was 0. 091 that was lower than any models based on 2 - index combination or single - index. Using the discriminant model based on three -index combination,the infection severity of 26 patients admitted during June 2015 were predicted with a high interrater a-greement(weighted Kappa coefficient:0. 670,P ﹤ 0. 001)compared to clinical diagnosis. Conclusion The discriminant model based on combination of PCIS,D - D and PCT could assist predicting the severity of pediatric infection earlier.
RESUMEN
Objective To explore the change of serum procalcitonin (PCT)in infectious diseases and the relationship between PCT and the severity of illness in children.Methods This was a single-center prospective study of serum procalcitonin concentration in children with infectious diseases.Ninty-five children with infectious diseases (mycoplasma infection 30 cases,viral infection 30 cases,bacterial infection 35 cases),hospitalized in PICU of Shengjing Hospital from April 2011 to April 2013,were divided into three groups:non-serious group(64 cases),serious group(20 cases)and very serious group(11 cases)according to pediatric critical illness score(PCIS).Bacterial infectious patients were divided into two groups:gram positive bacterial group(20cases),gram negative bacterial group(15 cases).Twenty children of non-infectious diseases during the same period were selected as the control group.Serum PCT levels were detected by using VIDAS BRAHMS PCT detection system(rapid semi-quantitative PCT test).Laboratory detection was conducted in Department of Laboratory Medicine,Shengjing Hospital of China Medical University.Results The serum PCT levels of the control,the bacterial infection,virus infection,and mycoplasma infection group were (0.41 ± 0.34) μg/L,(2.56 ± 0.38)μg/L,(0.52 ±0.44) μg/L and(0.21 ±0.10) μg/L.The serun PCT levels higher than or equal to 0.5 μg/L were defirned as positive.There was significant difference in PCT positive rate between bacterial infection group and the control grouP(x2 =28.05,P ＜0.05).The serum PCT levels of children with infectious diseases were higher than those of non-infection group,mycoplasma infection group and virus infection group(P ＜ 0.05).Besides,the PCT value of gram negative bacillus infection group was also obvious higher than gram positive infection group.There was no significant difference among the non-infection group,mycoplasma infection group and virus infection group(P ＞ 0.05).There was significant negative correlation between the serum PCT concentration and the PCIS score in children with infectious diseases (r =-0.579 ～-0.793,P ＜ 0.05).The higher concentration of PCT in children with the infectious diseases indicated higher severity illness scores,more complications,and longer length of hospital stay.Conclusions PCT may provide an informative and sensitive molecular marker for pathogen identification (bacterial infection,pneumonia mycoplasma infection or viral infection).In the early diagnosis of infectious disease,PCT assay can help predict the severity of the disease.
RESUMEN
Objective To investigate the change and clinical significance of soluble triggering receptor expression of myeloid cells-1 (sTREM-1) and soluble urokinase plasminogen activator receptor (suPAR) expression in children with sepsis.Methods There were 80 systemic inflammatory response syndrome (SIRS)patients who were included in the study,60 cases in the sepsis group,20 cases in the non-infectious SIRS group and 30 cases in the healthy control group.By using the enzyme-linked immunosorbent assay (ELISA)to dynamically monitor the levels of serum sTREM-1,suPAR in children with sepsis,the differences of sTREM-1,suPAR levels between children with sepsis and non-sepsis were observed,the correlation with the pediatric critical illness score(PCIS) was analyzed,and the sensitivity and specificity of sTREM-1,suPAR,C-reactive protein (CRP)and procalcitonin (PCT)and other biochemical markers were compared,and the value of sTREM-1,suPAR,CRP,PCT in the early determination and prognosis of sepsis were investigated.Results Serum sTREM-1,suPAR,PCT levels in sepsis group were significantly higher than non-infectious SIRS group and the healthy control group,and the difference was statistically significant (P ＜ 0.05),but the differences of serum CRP levels in non-infectious SIRS group and sepsis group were not statistically significant(P ＞ 0.05).In sepsis subgroup,serum sTREM-1,suPAR,PCT levels between the three groups were of statistically significant difference (P ＜ 0.05).Through dynamic monitoring of sepsis group,serum sTREM-1,suPAR,CRP,PCT levels had a gradual downward trend in 1,4,7 day,at each time point difference was statistically significant (P ＜ 0.05).Serum sTREM-1,suPAR levels in sepsis group had significant negative correlation with PCIS (r =-0.322,-0.333,P ＜ 0.05).The sensitivity and specificity of sTREM-1,suPAR,CRP,PCT on diagnosing sepsis were in a descending order,and sTREM-1 combined with suPAR has the highest sensitivity and specificity.Conclusions sTREM-1 and suPAR all can serve as indicators of infection and inflammation,as their expression level can reflect the severity of sepsis.sTREM-1 combined with suPAR diagnostic sensitivity and specificity of sepsis was significantly better than a single indicator of sTREM-1,suPAR,CRP,PCT.Combining multiple indicators can improve the accuracy of diagnosis.
RESUMEN
Objective To explore the value of N-terminal pro-brain natriuretic peptide (NT-proBNP) in assessing severity and predicting prognosis in children with severe hand-foot-mouth disease (HFMD).Methods A total of 119 eligible children with severe HFMD admitted in the pediatric intensive care unit were enrolled in this retrospective study from March 2012 to March 2014.According to NT-proBNP level,children were divided into ≤ 500 pg/mL group (n =70) and ＞ 500 pg/mL group (n =49) ; whereas according to severity,children were divided into severe-type (n =74) and critical-type (n =45) ; and based on 28 days outcome in children with critical-type HFMD,children were divided into fatal group (n =27) and survival group (n =18).The chi-square test,two-sample t test,rank sum test Pearson or Spearman' s correlation,area under the receiver operating characteristic curve (AUC) were used to analyze 119 children with severe hand-foot-mouth disease (HFMD).Results Within 24 hours after admission,NT-proBNP ＞ 500 pg / mL group had higher rates of fever,abnormal breathing,abnormal heart rate,abnormal systolic blood pressure,capillary refill time ＞ 2 seconds and higher levels of laboratory biomarkers than NT-proBNP ≤ 500 pg/mL group (P ＜ 0.05) ; and during hospitalization,the rates of pulmonary edema,pulmonary hemorrhage and death also higher than NT-proBNP ≤ 500 pg/mL group (P ＜ 0.05).NT-proBNP,BS,WBC were higher in critical-type group than severe-type group (P =0.00),while the PCIS (pediatric critical illness score) was lower in critical-type group (x2 =14.70,P =0.00).NTproBNP was higher in fatal group than that in survival group (t =-2.60,P =0.01),PCIS was lower in fatal group (Z=2.70,P=0.01); and there were no statistically significant differences in BS and WBC between fatal and survival groups (BS:t =-0.60,P=0.55; WBC:t =-0.72,P=0.48).NT-proBNP,BS and WBC were negatively correlated with PCIS (r values were-0.58,-0.46,-0.56,P values were 0.00).The AUCs of NT-proBNP,BS,WBC and PCIS to determine the severity of severe HFMD children were 0.94,0.80,0.74,and 0.97,respectively; and to predict 28 days survival in criticaltype HFMD were 0.73,0.56,0.53,and 0.73,respectively.Conclusions Higher level of NT-proBNP could prompt cardiopulmonary involvement.NT-proBNP could reflect the severity of illness and served as a sensitive marker in predicting 28-day survival,being better than BS and WBC.
