Significance of serum insulin combined with cardiac markers in evaluating sepsis associated encephalopathy / 中华急诊医学杂志

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.

Clinical features of pertussis and risk factors of severe pertussis in children / 中国小儿急救医学

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.

Application of heparin-binding protein in severe adenovirus pneumonia / 中华实用儿科临床杂志

Objective:To explore the application value of heparin-binding protein (HBP) in the early diagnosis and assessment of severe adenovirus pneumonia.Methods:A total of 90 children diagnosed with adenovirus pneumonia admitted in the Department 1 of Emergency and Pediatric Intensive Care Unit 1 in Hunan Children′s Hospital from January 2019 to March 2020 were recruited.HBP levels in children with adenovirus pneumonia were detected.The correlation between HBP with white blood cell count (WBC), neutrophil ratio (N), C-reactive protein (CRP), interleukin-6(IL-6) and erythrocyte sedimentation rate (ESR) were examined.Receiver operating characteristic(ROC) curve analysis was conducted to explore the value of HBP in the early diagnosis and assessment of severe adenovirus pneumonia.Children with adenovirus pneumonia were divided into severe adenovirus pneumonia group (severe group) and non-severe adenovirus pneumonia group (non-severe group) according to their severity.Those in the severe group were further divided into bronchiolitis obliterans(BO) group and non-BO group according to the occurrence of BO.Results:(1) The HBP level in children with adenovirus pneumonia was (49.47±34.19) μg/L, which was significantly higher in the severe group than that of non-severe group[(82.88±44.02) μg/L vs.(35.15±13.08) μg/L, t=15.349, P<0.05]. Children in the severe group were significantly younger, and they had a significantly longer length of stay, lower Pediatric Critical Illness Scores (PCIS), and higher inflammatory markers like HBP, WBC, N, CRP, IL-6, and ESR compared with those of the non-severe group (all P<0.05). No significant difference in the procalcitonin (PCT) level was detected between groups.(2) The HBP was positively correlated with inflammatory markers like WBC ( r=0.38, P<0.05), N ( r=0.26, P<0.05), CRP ( r=0.47, P<0.05), IL-6 ( r=0.76, P<0.05), and ESR ( r=0.35, P<0.05). However, HBP did not have a significant correlation with PCT ( r=0.097, P>0.05). (3) In the severe group, the HBP level of the children with invasive mechanical ventilation, oxygenation index(P/F index)≤ 200 mmHg (1 mmHg=0.133 kPa) and BO was significantly higher than that of the non-invasive mechanical ventilation, P/F index> 200 mmHg and non-BO (all P<0.05). (4) The area under the ROC curve of HBP, WBC, N, CRP, ESR and IL-6 in predicting the severity of adenovirus pneumonia were 0.915, 0.748, 0.770, 0.740, 0.820 and 0.798, respectively.When the cut-off value of HBP was 45 μg/L, the sensitivity and specificity of HBP were 81.48% and 85.71%, respectively. Conclusions:As an inflammatory mediator, HBP is involved in the inflammatory response of the body.It may be a useful new marker for the early diagnosis of severe adenovirus infection, which also has a certain value in the evaluation of the severity and prognosis of the disease.The findings provide a basis for early clinical intervention and treatment of adenovirus infection in children.

ObjectiveTo evaluate the feasibility and value of mini-clinical evaluation exercise (Mini-CEX) in clinical neurology practice.MethodsNinety-four interns were randomly divided into observation group and control group,students in control group were teached and managed in accordance with existing management while those in observation group were evaluated by teachers after the 1 st,2nd and 3rd week.At the end of clinical practice,all the students( including students in control group and observation group)were cross assessed by teachers based on the methods mentioned above.Results The time to complete the assessment was about 25 - 40 min.The scores of nervous system examination at the end of the training were significant different between observation group and control group and the scores of diagnosis and treatment on the basis of examination were also significant different between observation group and control group ( P ＜ 0.05 ).ConclusionThe Mini-CEX assessment and feedback to promote teaching effect is feasible in the practice process of neurology,it can make up for the deficiency of current examination.

Risk factors of vasovagal syncope / 国际儿科学杂志

Vasovagal syncope (VVS)is the most common clinical unexplained syncope,and its pathogenesis has not been fully understood yet.The contradictory reflection of cardiac autonomic nervous system caused by riggerring Bezold-Jarisch reflex,which could cause dilated blood vessels,blood pressure and cardiac output decreased,insufficient blood supply to the brain relate with syncope occurrence.Currently,most people consider it mainly relatel to the age and gender of patients,history of syncope,family history,mental and psychological factors,dietary habits and other factors,but the exact risk factors of VVS remains further study of multi-center and a large sample of data.
