ABSTRACT
Trajectories refer to the motion paths followed by objects in space. Disease trajectories, which depict the evolution of disease processes over time, are significantly important for assessing diseases, formulating treatment strategies, and predicting prognosis. Critical illness is one of the leading causes of death. With advances in critical care medicine, there is increasing focus on the occurrence and development of critical illnesses. Understanding the development trajectory of critical illness is helpful to promote the early identification, intervention, and treatment of high-risk patients, avoid prolongation of the course of disease, reduce the risk of multiple organ failure, and provide important reference for the development of targeted prevention and intervention strategies, thereby reducing the incidence and mortality of critical illness. In recent years, various trajectory modeling methods have been applied to the study of critical illness. These include, but are not limited to, latent growth curve modeling (LGCM), growth mixture modeling (GMM), group-based trajectory modeling (GBTM), latent transition analysis (LTA), and latent class analysis (LCA). The aim of this article is to review the definition of disease trajectories, the methods used in trajectory modeling, and their applications and future prospects in critical illness research.
ABSTRACT
Objective:To explore the clinical characteristics of children with septic shock and analyze the drug resistance of blood culture positive bacteria.Methods:The clinical data,positive blood culture strains and drug sensitivity results of 127 children with septic shock admitted to the Department of Intensive Care Medicine of Hunan Children's Hospital from September 2015 to August 2021 were retrospectively analyzed.Results:A total of 134 strains of bacteria or fungi were isolated from the blood culture samples of 127 children with septic shock,and gram-negative strains were the main ones,accounting for 67.16% (90/134).Haemophilus influenzae and Escherichia coli were the main gram-negative bacteria,accounting for 38.81% (52/134) and 20.15% (27/134)，respectively,while Streptococcus pneumoniae was the main gram-positive bacteria,accounting for 8.21% (11/134),and Candida albicans was the main fungus,accounting for 10.45% (14/134).The number of white blood cells,the levels of serum C-reactive protein,procalcitonin,venous blood sugar and arterial blood lactic acid in patients were all significantly higher than normal values,and the white blood cells count and neutrophil percentage in gram-positive bacterial infections were significantly higher than those with gram-negative bacterial infections and fungal infections( P<0.05).Procalcitonin increased most obviously when infected by gram-negative bacteria,and the difference was statistically significant ( P<0.05).Gram-positive strains were sensitive to vancomycin,teicoplanin,and linezolid,but only 50% of Streptococcus pneumoniae were sensitive to penicillin.Gram-negative strains had relatively high drug resistance,among which Klebsiella pneumoniae were only highly resistant to imipenem,cilastatin and levofloxacin,reaching 50%.Haemophilus influenzae was resistant to cephalosporins and β-amides enzyme antibiotic,and the drug sensitivity rate of lactamase antibiotics was high,with a resistance rate of 50% only to ampicillin,cefuroxime,amikacin,and compound sulfamethoxazole.There were not many fungal strains,and most antifungal drugs were effective against blood culture-positive fungi. Conclusion:The main pathogens of infection in children with septic shock are gram-negative bacteria,and have high resistance to general antibiotics.We should pay attention to their drug resistance when using antibiotics empirically.
ABSTRACT
Hemorrhagic stroke accounts for half of childhood stroke, and its etiology is complex, including anatomical abnormalities, infections, hematological diseases, genetic factors, etc.The etiology and risk factors are significantly different from those of adults.Due to the particularity of child population, once a hemorrhagic stroke occurs, the remaining neurological deficits will bring a great burden to children themselves, families, and society.The age of children with hemorrhagic stroke is young, and the incidence rate is lower than that of common respiratory and digestive diseases.It is necessary to improve the cognition and education of clinicians and children′s families on hemorrhagic stroke.Therefore, comprehensive understanding, early identification, and precise treatment of pediatric hemorrhagic stroke are of great significance for early prevention, treatment, and reduction of disability rates.
ABSTRACT
Objective:To explore the clinical value of serum insulin combined with cardiac-related markers in evaluating the severity of sepsis associated encephalopathy (SAE).Methods:The clinical data of 130 children with sepsis who admitted to the Pediatric Intensive Care Unit of Hunan Children's Hospital from January 2018 to December 2021 were analyzed retrospectively, and the differences of serum insulin and cardiac-related markers in children with sepsis and SAE were compared.Results:The levels of serum insulin, creatine kinase isoenzyme, hypersensitive troponin T, and N-terminal cerebral urine peptide in the SAE group were significantly higher than those in the non-SAE group ( P<0.05), but there was no significant difference in heart rate and lactic acid ( P>0.05). The levels of serum insulin, creatine kinase isoenzyme, hypersensitive troponin T, N-terminal cerebral urine peptide and lactic acid in the death group were significantly higher than those in the survival group ( P<0.05), while the heart rate was not significantly different ( P>0.05). The area under ROC curve of serum insulin, creatine kinase isoenzyme, hypersensitive troponin T, and N-terminal cerebral urine peptide in predicting SAE were 0.841, 0.599, 0.700, and 0.667, respectively; in terms of judging the prognosis of sepsis, the area under ROC curve were 0.647, 0.669, 0.645, and 0.683, respectively; and in terms of judging the prognosis of children with SAE, the areas under the ROC curve were 0.509, 0.682, 0.666 and 0.555, respectively. Binary logistic regression equation was established with serum insulin, creatine kinase isoenzyme, hypersensitive troponin T, and N-terminal cerebral urine peptide: Y=8.153×NT-proBNP+1.704×CTnT-hs+27.121×insulin+0.946×CK-MB+1.573. The area under the ROC curve of the new variable Y in predicting sepsis SAE, evaluating the prognosis of sepsis, and predicting the prognosis of children with sepsis and SAE was 0.890, 0.756, and 0.729, respectively. Conclusions:Serum insulin, creatine kinase isoenzyme, hypersensitive troponin T, and N-terminal cerebral urine peptide can be used alone to determine the severity of sepsis and sepsis in children with SAE. The combined value of the four indicators is obviously better than that of the single indicator. The combined application of the four indicators may better evaluate the severity of sepsis and SAE.
ABSTRACT
Objective:To investigate the value of the level of heparin-binding protein(HBP)in bronchoalveolar lavage fluid(BALF)on the evaluation of severe pneumonia in children.Methods:A total of 94 children with severe pneumonia who underwent bronchoscopy and bronchoalveolar lavage were admitted at Hunan Children′s Hospital, and HBP levels in BALF were detected.According to the etiological results, the patients were divided into non-bacterial infection group(19 cases) and bacterial infection group(75 cases). According to the existence and severity of acute respiratory distress syndrome (ARDS), the cases were divided into non-ARDS group(65 cases), mild ARDS group(23 cases) and moderate to severe ARDS group(6 cases).Results:The HBP level of BALF in the bacterial infection group was higher than that in the non-bacterial infection group, and the difference was statistically significant[ 20.77(5.90, 73.50)ng/mL vs.5.9(5.90, 7.64)ng/mL, Z=12.500, P<0.001]. The HBP level of BALF in the moderate to severe ARDS group[300.00(169.29, 300.00)ng/mL] was significantly higher than those in the non-ARDS group[11.90(5.90, 36.95)ng/mL] and the mild ARDS group[15.13(7.41, 46.44)ng/mL], and the difference was statistically significant( H=14.718, P=0.001). In predicting the presence of bacterial infection in severe pneumonia, the area under the receiver operating characteristic curves of BALF HBP, serum procalcitonin (PCT) and serum C-reactive protein(CRP) were 0.758, 0.737, and 0.732, respectively.When the optimal truncation values of BALF HBP, serum PCT and serum CRP were 8.40 ng/mL, 0.16 ng/mL, and 8.39 mg/L, the predicted sensitivities were 70.7%, 69.3%, 46.7%, and the predicted specificity were 79.0%, 79.0%, 94.7%, respectively. Conclusion:The level of HBP in BALF in children with severe pneumonia increases with the severity of ARDS, and significantly increases in the positive group of bacterial infection, which can be used as one of the auxiliary indicators to evaluate the severity of severe pneumonia and bacterial infection in children.
ABSTRACT
Objective:To investigate the etiology, prognosis and clinical characteristics of abnormal serum amylase and lipase in children.Methods:This study was a retrospective study.A total of 7 813 children older than 28 days who had their serum amylase and lipase detected in Hunan Children′s Hospital from August 2017 to August 2020 were included as the study subjects.Children with acute and chronic pancreatitis were excluded.The age, gender, impatient department, imaging exams, discharge outcomes, main diagnosis, diagnostic ICD10 code, and the highest values of serum amylase and lipase during hospitalization were collected through the medical record system.According to the levels of serum amylase and lipase, the children were divided into 3 groups.Patients in group A had normal serum amylase and serum lipase levels.The serum amylase or lipase levels of patients in group B was 1 to 3 times higher than that of group A. The serum amylase or lipase levels in group C was 3 times higher than that of group A. Group B and group C had abnormal pancreatic enzyme levels.According to the prognosis, patients were divided into the survival group and the death group.The relationship of the occurrence of abnormal serum amylase and lipase levels with the age, sex, disease type and prognosis of children was analyzed.Results:The ratio of abnormal trypsin in male and female was 11.5% and 12.9%, respectively.The number of children with abnormal pancreatic enzyme levels in the 28 day -1 year old group, >1-3 years old group, >3-6 years old group, >6 -12 years old group and > 12 year old group were 37 cases (4.6%), 185 cases (15.4%), 199 cases (10.5%), 431 cases (13.9%), and 94 cases (11.7%), respectively.The mortality rate was 1.6% (112/6 867 cases) in group A, 5.2% (32/617 cases) in group B, and 7.6% (25/329 cases) in group C. The mortality risk of group B and C was both higher than that of group A. Compared with group A, the OR (95% CI) of group B and group C was 3.30 (2.21-4.93) and 4.96 (3.17-7.77), respectively.In group C, the top five diseases were parotitis (26.4%), cholangiectasis (11.6%), choledochal cysts (8.5%), gastroenteritis (4.5%) and sepsis (3.3%). Conclusions:Pancreatic enzyme abnormalities in children are associated with adverse prognosis.Pancreatic enzyme abnormalities are more prone to occur in children aged >1-3 with mumps, digestive diseases and congenital digestive system structural deformities.In addition, children with sepsis are also easy to present pancreatic enzyme abnormalities.Clinical attention should be paid to the possibility of secondary pancreatic damage in children with sepsis.
ABSTRACT
Objective:To observe the changes of corneal curvature and ocular surface after congenital ptosis.Methods:A total of 188 patients with congenital blepharoptosis were treated with frontal muscle flap suspension, levator eyelid muscle shortening and fixation, and levator aponeurosis according to different conditions. The postoperative correction effect, corneal curvature, and ocular surface changes were observed.Results:There was no significant difference in the good correction rate among the three methods ( P>0.05). The corneal curvature at 3 months after operation was lower than that before operation and 7 days after operation ( P<0.05). The fluorescein staining score at 7 days after operation was higher than that before operation and 3 months after operation ( F=2 910.05, P<0.05). The tear film rupture time at 7 days after operation was significantly shorter than that before operation and 3 months after operation ( F=758.12, P<0.05). There was no significant difference in tear secretion test before operation, 7 days after operation and 3 months after operation ( P>0.05). The conjunctival congestion score at 3 months after operation was lower than that at 7 days after operation, and the incidence of meibomian gland dysfunction and abnormal eyelash angle at 3 months after operation was lower than that at 7 days after operation ( t=113.56, χ 2=11.02, 11.46, P<0.05). 3 months after operation, the average diopters of 3 mm and 5 mm were higher than those before operation ( t=12.35, 15.19, P<0.05). Conclusions:Frontal muscle suspension, levator eyelid muscle shortening and fixation, and levator aponeurosis are effective in treating congenital blepharoptosis, and can effectively improve the ocular surface and corneal curvature. Clinically, the appropriate one can be selected according to the condition of the child correction method.
ABSTRACT
Objective:To study the clinical features of children with pertussis and the risk factors of severe pertussis.Methods:A retrospective analysis was performed based on clinical data and laboratory examination results of hospitalized children with pertussis who admitted to the intensive care unit, respiratory department, and emergency general department at Hunan Children′s Hospital from January 2019 to March 2020.According to the age, the patients were divided into age ≤3 months group( n=58)and age >3 months group( n=64). According to sputum culture, 63 cases were divided into negative sputum culture group and 59 cases were positive sputum culture group.The patients were also divided into vaccinated group( n=19)and unvaccinated group( n=103). Severe disease was seen in 28 cases, and the other 94 cases had the modest disease.The clinical characteristics between two groups were compared, and the risk factors of severe pertussis pneumonia were analyzed. Results:The hospitalization days in age ≤3 months group was higher than that in age >3 months group.It was also found that shortness of breath, apnea, cyanosis after coughing, heart rate decline were more common in age ≤3 months group than those in age >3 months group( P<0.05). The incidences of respiratory failure and heart failure in positive sputum culture group were higher than those in negative sputum culture group.Clinical characteristics such as hospitalization days, hospitalization expenses, peak white blood cell count, peak lymphocyte count, and incidence of bacterial infection were higher in severe pertussis group than those in non-severe pertussis group( P<0.05). Four patients were treated with exchange blood transfusion, and one patient died.Logistic regression analysis revealed that fever, wheezing, cyanosis after coughing and white blood cell count>20×10 9/L were risk factors for severe pertussis.White blood cell count of 20×10 9/L and lymphocyte count of 14×10 9/L had the highest sensitivity and specificity in predicting severe pertussis(0.71, 0.78; 0.54, 0.79). Conclusion:The younger the children are, the more likely they have shortness of breath, apnea, cyanosis, heart rate falls, and the longer the hospital stay.Bacterial infection will aggravate pertussis.Patients with fever, wheezing, cyanosis after coughing, and white blood cell count>20×10 9/L are more likely to develop severe pertussis.The white blood cell count >20×10 9/L and the lymphocyte count >14×10 9/L are associated with severe pertussis.
ABSTRACT
Objective:To evaluate the effect of serum cytokines and immune typing on the severity and prognosis of children with sepsis.Methods:One hundred and sixty children with sepsis admitted to No.2 PICU from May 2018 to May 2019 at Hunan Children′s Hospital were enrolled.Vital signs, blood routine and blood biochemical indexes of the children were collected within 24 hours after admission.Serum cytokine concentrations of interleukin(IL)-2, IL-4, IL-6, IL-10, tumor necrosis factor(TNF)-α, and interferon (IFN)-γ were tested at the same time.According to the worst condition during the first 24 h after admission, and the consensus diagnostic criteria of experts in the diagnosis and treatment of septic shock in children in 2015, the patients were divided into sepsis group(76 cases) and severe sepsis group(84 cases). According to the prognosis of 28 days, the patients were divided into survival group(134 cases)and death group(26 cases). The differences of cytokine concentration and the composition of immune state among groups were compared.Results:The levels of IL-2[2.40(2.40, 2.55)pg/mL vs. 2.40(2.40, 3.76)pg/mL], IL-6[60.54(23.22, 250.38)pg/mL vs. 21.47(8.83, 57.94)pg/mL], IL-10[50.85(21.74, 217.12)pg/mL vs. 14.99(9.23, 28.79)pg/mL] , TNF-α[2.75(2.40, 5.15)pg/mL vs. 2.40(2.40, 3.23)pg/mL] and IFN-γ[8.01(4.34, 37.28)pg/mL vs.2.62(2.62, 28.56)pg/mL] in the severe sepsis group were significantly higher than those in the sepsis group( P<0.05). The levels of IL-10[99.57(10.51, 646.96)pg/mL vs. 23.17(11.74, 57.30)pg/mL] and TNF-α[3.08(2.40, 5.13)pg/mL vs. 2.45(2.40, 3.80)pg/mL] in the death group were significantly higher than those in the survival group( P<0.05). The risk of death in children with mixed antagonistic response syndrome (MARS) was significantly higher than those without MARS( OR 3.75, 95% CI 1.302-10.804). Conclusion:The increased concentrations of IL-2, IL-6, IL-10, TNF-α, and IFN-γ are significantly correlated with the severity of sepsis in children.Increased IL-10 concentration and the occurrence of MARS are significantly correlated with poor prognosis.The occurrence of MARS in children with sepsis should be highly vigilant for the poor prognosis.
ABSTRACT
Objective:To investigate the changes of inflammatory factors, serum amylase and lipase and pancreatic damage at different time points after establishment of cecal ligation and perforation in a rat model of sepsis, which provides a stable and reliable animal model for the study of pancreatic injury following sepsis in children.Methods:Sixty male SD rats were randomly divided into 6 h group, 12 h group, 24 h group and 48 h group in control group, sham group and cecal ligation and puncture (CLP) group.Rat model of sepsis was established by cecal ligation and perforation in CLP group, the sham group was treated with sham operation, and rats in control group were not treated.The levels of interleukin (IL)-1β, IL-10, amylase and lipase in each group were detected, and pancreatic tissue was taken for HE staining.Results:In this model, the 48 h survival rate of rats in the CLP group was 70%.With the prolongation of postoperative time in the CLP group, pancreatic tissue congestion, cell edema, and inflammatory cell infiltration gradually worsened.The pathological changes of pancreatic tissue in the Sham group were mild.The expression levels of IL-1β in CLP group and sham group increased first and then decreased, and reached the peak at 12 h. The expression levels of IL-1β in CLP group were significantly higher than those in control group and sham group at all time points( P<0.05). The expression level of IL-10 showed a gradually increasing trend, reaching a peak at 48 h. The expression level of IL-10 in CLP group was significantly higher than that in control group and sham group at all time points( P<0.05), which in sham group was significantly higher than that in control group( P<0.05). Serum amylase and lipase in CLP group showed an upward and then downward trend, reaching the peak at 24 h. The serum amylase levels at 24 h and 48 h were significantly higher than those in control group and sham group( P<0.05). Serum amylase levels in sham group were significantly different from those in control group at 12 h, 24 h and 48 h( P<0.05). Serum lipase level at 12 h, 24 h and 48 h was significantly higher than that in control group and sham group( P<0.05). There was no significant difference in serum lipase between sham group and control group( P>0.05). Conclusion:After CLP modeling, IL-1β, IL-10 elevation and pancreatic pathological changes appeared at the early stage, and the pathological changes gradually increased with time.Significant differences in serum amylase and lipase began to appear at 24 h and 12 h respectively.
ABSTRACT
Objective:To analyze the epidemiological characteristics, clinical characteristics and blood purification effect of mushroom poisoning in children.Methods:A retrospective study was conducted on 51 children with acute mushroom poisoning admitted to Hunan Children′s Hospital from 2002 to 2020.The epidemiological and clinical characteristics were analyzed, and the prognosis of children with different incubation periods was analyzed and compared.Among them, 36 critically ill children were treated with blood purification.Results:The age distribution was 66(43, 115)months.Mushroom poisoning had obvious seasonal and spatial aggregation.The first symptom was mainly manifested by digestive tract, which was manifested as vomiting, abdominal pain and diarrhea, accounting for 94.1% patients(48/51). The gastrointestinal tract type accounted for 45.1%(23/51) of the clinical types and the multi-organ damage type accounted for 51.0% patients(26/51). The length of hospital stay was 6(3, 11)days.Among them, early onset accounted for 45.1% patients(23/51), late onset accounted for 54.9% patients(28/51). Early onset hospitalization was shorter, about 4(2, 7)days, and fewer organs 1(0, 3) were damaged.The length of hospital stay of late onset was 8(3, 12)days, and the number of damaged organs was 4(2, 4). There was a statistically significant difference( P<0.05). Late onset patients had more severe organ function damage, including liver function, coagulation function, renal function, myocardial enzyme, and there was no significant difference in the final outcome between two groups.In 36 children who were given blood purification treatment, alanine aminotransferase, aspartate aminotransferase, prothrombin time, international normalized ratio, blood urea nitrogen, and lactate dehydrogenase were significantly improved, with statistically significant differences( P<0.05). Conclusion:Mushroom poisoning has obvious seasonal and geographical distribution characteristics; the first manifestation is mainly gastrointestinal symptoms; the clinical types are more common in gastrointestinal and multiple organ damage types.Children with early onset have shorter hospital stays and fewer complications than later onset.Blood purification treatment can significantly improve liver function, kidney function and blood coagulation function in children with toadstool poisoning.
ABSTRACT
Objective:To discuss the role of continuous blood purification (CBP) therapy in children with severe adenovirus pneumonia.Methods:A total of 114 children with severe adenovirus pneumonia admitted to the Department of PICU at Children′s Hospital of Hunan Province from June 2018 to July 2019 were selected as the research objects.According to whether treated with CBP, they were divided into CBP group and control group.The following indicators during the process of treatment were compared between two groups, including respiratory mechanics indicators[respiratory index(PaO 2/FiO 2), dynamic lung compliance(Cdyn)]; hemodynamic indicators(heart rate and mean arterial pressure); changes in levels of inflammatory factors interleukin(IL)-6, IL-10, tumor necrosis factor(TNF)-α and the prognosis 28 days after admission. Results:The respiratory mechanics index, serum IL-6 and TNF-α levels of two groups after treatment were significantly lower than those before treatment, and the serum IL-10 level was significantly higher than that of this group before treatment.There were statistical differences in the CBP group before and after treatment, while there was no statistical difference in control group.In the CBP group, the serum IL-6 and TNF-α levels after treatment were significantly lower than those of the control group( P<0.05), and the serum IL-10 level was significantly higher than that of the control group( P<0.05). The 28-day mortality rate of patients in CBP group was 8.6%(3/35), which was significantly lower than 13.9%(11/79) of control group ( P<0.05). Conclusion:CBP could improve the main respiratory mechanical indexes of adenovirus pneumonia and decrease the level of inflammatory cytokines.

Objective:To retrospectively analyze the clinical application of extracorporeal membrane oxygenation (ECMO) in severe adenovirus pneumonia, and to evaluate the application value of ECMO in children with severe adenovirus pneumonia.Methods:Children diagnosed with severe adenovirus pneumonia and intervened with ECMO in the Hunan Children′s Hospital from January 1, 2018 to December 31, 2019 were recruited in this study for analyzing.The gender, age, clinical manifestations, mechanical ventilation duration, ECMO duration, the length of hospital stay, complications and prognosis were collected and analyzed.Results:A total of 4 children were included in the study, involving 2 cases were successfully evacuated from ECMO.Finally, 3 children died, and 1 case survived.Three death cases had a longer than 18 days of duration from the onset to the start with ECMO.Their ventilator assist time before star-ting ECMO was 3-5 days, and ECMO intervention time was longer, with the maximum of 27.5 days.The survived case had an 11-day duration from the onset to the start with ECMO, and the ventilator assisted time and ECMO intervention time were 5 days, and less than 10 days, respectively.Conclusions:ECMO treatment for children with severe adenovirus pneumonia has a low success rate, but it is still the most important way to save children.Early application of ECMO can improve the prognosis of children with severe adenovirus pneumonia.
ABSTRACT
Objective:To summary the mixed infection as well as clinical characteristics and analyze the risk factors for mixed infection of severe adenovirus pneumonia(SAP) in children.Methods:The clinical data of 114 children with SAP were retrospectively analyzed.Multivariate Logistic regression analysis was performed to assess the risk factors for mixed infection.Results:The incidence age was from 6 months to 2 years(62.5%). High fever(94.7%), cough(98.2%), dyspnea(86.8%) and lethargy(95.6%) were the main symptoms.Laboratory examination showed that children with SAP were prone to increased white blood cell count, C-reactive protein, procalcitonin, aspartate aminotransferase, alanine aminotransferase and CK-MB, as well as decreased proportion of CD3 + , CD4 + , CD8 + , CD4 + /CD8 + and NK cells.The main complications intrapulmonary organ were respiratory failure(80.7%). The main complications extrapulmonary organ were circulatory complications (55.3%). SAP was easily combined with other pathogenic infections.Streptococcus pneumoniae(22.9%)was the most common bacterial pathogen.Respiratory syncytial virus(10.0%)were the most common virus, in addition, mycoplasma pneumoniae(17.1%) was also common.Multivariable Logistic regression analysis showed that the decreasing ratio of CD4 + /CD8 + and NK cells, congenital heart disease and congenital airway dysplasia were the independent risk factors for mixed infection of SAP in children( P<0.05). Conclusion:The SAP patients could easily suffer from mixed infection and high fatality rate.Immune dysregulation is the important risk factors for mixed infection of SAP in children.So immunoregulatory treatment is very important.
ABSTRACT
Severe pulmonary infection is one of important causes of death for children under five years old in China, and early identification of the cause and severity of lung infections is important for guiding clinical interventions. Heparin-binding protein (HBP) is a protein with bactericidal activity, and its concentration is very low in healthy people. Lung bacterial infection, acute lung injury or acute respiratory distress syndrome, which can lead to permeability of vascular endothelial cells increased, thus HBP in blood or tissue fluid can be significantly increased. It has certain guiding significance for the early identification of bacterial infection and judgment of the severity of the disease. This study reviewed the evaluation role of HBP in lung infection and severity of illness.
ABSTRACT
Objective:To analyze the predictive value of the mortality risk score for severe hand, foot and mouth disease(MRSHFMD) system for the complications and mortality risk of severe hand, foot and mouth disease(HFMD) in children.Methods:This study included 354 children with severe HFMD who admitted in the pediatric intensive care unit(PICU) of Hunan Provincial Children′s Hospital from March 2012 to March 2014.The patients were grouped according to whether they had complicated nervous system damage, pulmonary edema, pulmonary hemorrhage and circulatory failure in the course of disease, and the prognosis was grouped according to their 28 d survival.The worst values of white blood cell count, blood glucose, blood lactic acid, N-terminal pro-brain natriuretic peptide, within 24 hours after admission were used to score MRSHFMD.The predictive value of MRSHFMD for nervous system damage, pulmonary edema, pulmonary hemorrhage, circulatory failure, and prognosis were evaluated using the receiver operating characteristic(ROC)curve.Results:The blood glucose, white blood cell count, blood lactic acid value, N-terminal pro-brain natriuretic peptide and MRSHFMD score of the children with HFMD complicated with nervous system damage, pulmonary edema, pulmonary hemorrhage and circulatory failure were significantly higher than those in the non-complicated groups( P<0.01). When the cut-off value of MRSHFMD score was 3, the area (95% CI) under the ROC curve were 0.723 (0.643-0.804), 0.870 (0.793-0.946), 0.921 (0.85-0.992), 0.944 (0.867-1.000) and 0.954 (0.000-1.000) of nervous system damage, pulmonary edema, pulmonary hemorrhage, circulation failure and death in children with HFMD, respectively.The specificity and sensitivity of predicting nervous system damage, pulmonary edema, pulmonary hemorrhage, circulatory failure and death were 44.6% and 95.8%; 67.5% and 95.5%; 83.3% and 95.1%; 89.3% and 95.1%; 90.9% and 93.7%, respectively. Conclusion:MRSHFMD system is an effective tool to predict HFMD complications of pulmonary hemorrhage, circulatory failure, and death, which is worthy of clinical promotion.

When the cut-off value of MRSHFMD score was 3, the area (95%CI) under the ROC curve were 0.723 (0.643-0.804), 0.870 (0.793-0.946), 0.921 (0.85-0.992), 0.944 (0.867-1.000) and 0.954 (0.000-1.000) of nervous system damage, pulmonary edema, pulmonary hemorrhage, circulation failure and death in children with HFMD, respectively.The specificity and sensitivity of predicting nervous system damage, pulmonary edema, pulmonary hemorrhage, circulatory failure and death were 44.6% and 95.8%; 67.5% and 95.5%; 83.3% and 95.1%; 89.3% and 95.1%; 90.9% and 93.7%, respectively.@*Conclusion@#MRSHFMD system is an effective tool to predict HFMD complications of pulmonary hemorrhage, circulatory failure, and death, which is worthy of clinical promotion.
ABSTRACT
Objective To compare the value of three neonatal referal scoring systems in predicting the risk of mortality in preterm and low birth weight infants. Methods Six hundred and fourty-nine prema-ture neonates-fetal age <37 weeks and birth weight <2 500g infants were transported to the neonatal inten-sive care unit of Hunan Children′s Hospital from January 1 to December 31,2016. The score of transport risk index of physiologic stability(TRIPS),mortality index for neonatal transportation(MINT)score and transport related mortality score(TREMS)were conducted for them. Results TRIPS,MINT and TREMS scoring sys-tems of the death group were significantly higher than those of the survival group(P<0. 001). In the multi-variate Logistic regression analysis,systolic blood pressure,reaction of foot hit and the intubation of respirato-ry in the TRIPS entered the regression equation. The birth weight,blood pH value and whether intubation when contacted in the MINT score were included in the equation. Hypotension,hypoxemia and hypercapnia of TREMS were entered the regression equation,indicating these factors were the independent risk factors for death in preterm and low birth weight infants. The area under the receiver operating characteristic and 95%CI of TRIPS,MINT and TREMS were 0. 843(0. 796,0. 889),0. 796(0. 722,0. 871)and 0. 712(0. 639,0. 786), respectively. Conclusion The TRIPS is more accurate than MINT and TREMS in predicting the risk of ref-erral mortality in referaling preterm and low birth weight infants.
ABSTRACT
Objective To compare the clinical efficacy of different blood purification methods in children with acute liver failure,and to explore the clinical application mode,time and prognosis of blood pur-ification in children with acute liver failure. Methods The clinical data of 85 children with acute liver failure admitted to PICU of Hunan Children′s Hospital from January 2010 to October 2016 were retrospectively ana-lyzed. Sixteen patients were treated with general integrated medical treatment(conservative group). Twenty-seven patients were treated with continuous venovenous hemodiafiltration ( CVVHDF) model non-biological artificial liver on the basis of general integrated medical treatment(CBP group). Sixteen cases were treated with plasma exchange ( PE group). Twenty-six cases were treated with plasma exchange combined with CVVHDF mode (combination group). The main biochemical indexes,coagulation function,model for end-stage liver disease(MELD) score and delta MELD before and after treatment among groups were compared. Results Compared with those before treatment,the improvement of liver function and prognosis in the con- servative was not significant after treatment. There were significant differences in the improvement of liver function and prognosis among the other three groups treated with non-biological artificial liver. Comparing the biochemical indexes and prognosis of three groups of children treated with different modes of non-biological artificial liver,there was no significant difference in the total effective rate between PE group and CBP group [56. 3% (9/16) vs 55. 6% (15/27),P>0. 05]. The total effective rate of combined group[84. 6% (22/26)] was significantly higher than those of PE group and CBP group. There was no significant difference in the improvement of liver function between PE group and CBP group (all P>0. 05),but the indexes of liver function in combined group were significantly lower than those in PE group and CBP group ( P<0. 05). It significantly increased prothrombin activity,albumin and alpha-fetoprotein levels(all P<0. 05). At the same time,procalcitonin, sequential organ failure assessment scores, pediatric end-stage liver disease scores and MELD scores in the death group were significantly higher than those in the survival group,and there were significant differences between the two groups. However,the effect of non-biological artificial liver was not good in the subgroups of MELD<25 and MELD>40. Conclusion PE and CBP have a good effect on chil-dren with acute liver failure,and if combined with the two methods can improve the therapeutic effect. At the same time,MELD score should be monitored in children with acute liver failure,and non-biological artificial liver therapy should not be recommended for children with MELD<25 and MELD>40.
