Objective To develop a home skin care guidance scheme for newborns,and initially implement it to reducing the risk of skin-related issues.Methods Searching both domestic and international databases,we identified relevant literature.Following a quality evaluation,evidence integration,and group discussions,we developed the con-tent of the home skin care guidance for newborns.Subsequently,we refined this content through 2 rounds of expert consultations to finalize the scheme.To initially implement the scheme,we conveniently selected 20 healthy new-borns born between August 1st and 15th,2024,at a tertiary-level comprehensive hospital in Fujian Province as an experimental group.Their parents received skin care guidance based on our scheme via a WeChat platform.In contrast,we selected another group of 20 healthy newborns delivered between July 1st and 15th,2024,at the same hospital as a control group;their parents were provided with conventional skin care guidance.We compared the in-cidence rates of diaper dermatitis and eczema between these 2 groups of newborns at a month of age.Results A total of 33 experts from 30 tertiary hospitals across 19 provinces(including autonomous regions and municipalities)were invited to participate in a questionnaire survey.The response rates for both rounds of expert questionnaires reached 100％.The authority coefficients for the experts were recorded at 0.78 and 0.83,while the Kendall concor-dance coefficients were found to be 0.188 and 0.142(all P＜0.001).The final newborn home skin care guidance scheme consists of 6 first-level items,41 second-level items,such as the selection of newborn care products,methods for neonatal bathing and prevention of neonatal diaper dermatitis,and so on.Preliminary application results indicated that the incidence of diaper dermatitis in the experimental group was significantly lower than that observed in the control group,with a statistically significant difference noted(P=0.047).There was no significant difference in the incidence of eczema between the 2 groups at the age of a month(P=0.201).Conclusion The Neonatal Home Skin Care Guidance Scheme for newborns has been demonstrated to be scientific,reliable and feasible.The implementa-tion of this scheme has proven beneficial in reducing the incidence of diaper dermatitis at a month of age.Howev-er,the sample size needs to be expanded to further verify its implementation effect.

Objective:To analyze the predictive factors associated with late-onset sepsis(LOS) in very low birth weight infants,and to develop a risk prediction score scale applicable to these infants three days postnatal.This will provide valuable insights for early diagnosis and timely intervention.Methods:Very low birth weight infants admitted to the Children's Hospital of Fudan University from January 1,2022,to June 30,2024,were selected as research subjects.These infants were categorized into two groups:the LOS group and the non-LOS group,based on whether they developed LOS.LASSO regression analysis,alongside univariate and multivariate regression analyses,was employed to identify predictive factors for LOS in this population.A Logistic model was constructed using the optimal combination of predictive variables,and a risk assessment scale was subsequently developed.The prediction performance of the model was evaluated using the Hosmer-Lemeshow chi-square test and the receiver operating characteristic curve.Results:A total of 444 cases of very low birth weight infants were included,of which 185 had LOS and 259 did not.After screening the variables,seven independent factors were included into the model:birth weight,gestational age,tracheal intubation,abnormal skin color,abdominal distension,elevated C-reactive protein levels,and right hand perfusion index.A predictive scoring scale was developed based on the regression coefficients of each variable,with corresponding risk scores assigned as follows:1,4,3,2,1,1,and 2; a score of ≥3.5 indicated high-risk groups.The Hosmer-Lemeshow test results demonstrated that χ2 = 7.602( P = 0.473).The area under the receiver operating characteristic curve was 0.792 ( P<0.001),with a sensitivity of 73.5% and specificity of 71.0%. Conclusion:The risk score scale developed in this study exhibits significant predictive capability,providing valuable insights for clinical medical personnel to assess the risk of LOS in very low birth weight infants during the early postnatal period.

Objective:To analyze the changes of peripheral perfusion index (PPI) with late-onset sepsis (LOS) in very low birth weight infants during hospitalization.Methods:Very low birth weight infants admitted to the neonatal intensive care unit of Children′s Hospital of Fudan University from August 1, 2021 to August 31, 2022 were consecutively included.Infants with admission age ≥three days and unstable circulation, or positive blood culture within three days after birth were excluded.From the day of admission, the PPI values of the right hand and either foot of the infants were measured with Masimo SET Radical-7 everyday while whether LOS occurred during hospitalization was observed.The mean PPI curve of very and extremely low birth weight infants without LOS was plotted.For those with LOS confirmed by blood culture, the PPI change trajectory three days before and after the occurrence of LOS was drawn, and the change trend of PPI before the occurrence of LOS was analyzed by trend chi-square test.Non-parametric test was used to analyze the effect of LOS on pre- and post-ductal PPI values.Results:A total of 107 very low birth weight infants were included in the final analysis.Among them, there were 11 infants confirmed as LOS by blood culture, 37 infants diagnosed as clinical LOS, and 59 infants without LOS.Pre-and post-ductal PPI values of very low birth weight infants without LOS were 2.06±1.30 and 1.72±0.92, respectively; those with clinical LOS were 1.90±0.94 and 1.58±0.83, respectively; those with LOS confirmed by blood culture were 1.92±1.11 and 1.62±0.82, respectively.For infants with LOS confirmed by blood culture, the pre-and post-ductal PPI values showed a continuous downward trend during three days before the onset of disease, with the lowest PPI values on the first day before the diagnosis of blood culture.The downtrend of pre-ductal PPI was statistically significant ( χtrend2=5.57, P<0.05). Conclusion:The PPI value of very low birth weight infants show a downward trend when LOS occurs.It should be observed dynamically in clinical practice, which is helpful to suspect or identify LOS as early as possible.

Objective:To identify the risk factors for acute lung injury (ALI) after pediatric living donor liver transplantation (LDLT) and evaluate the predictive value.Methods:The pediatric patients (all diagnosed with congenital biliary atresia) who underwent parental liver transplantation in our center from January to December 2021 were selected. Perioperative data were obtained through the electronic medical record system, and the pediatric patients were divided into non-ALI group and ALI group according to whether ALI occurred or not at 1 week after surgery. The factors of which P values were less than 0.05 between groups would enter the multivariate logistic regression analysis to stratify the risk factors for ALI after pediatric LDLT, and the value of the risk factors in predicting intraoperative ALI was evaluated using the receiver operating characteristic curve. Results:A total of 140 pediatric patients were enrolled in the analysis, and the incidence of ALI was 30.7%. The results of the multivariate logistic regression analysis showed that preoperative pediatric end-stage liver disease score, preoperative serum NT-pro-BNP concentrations, intraoperative volume of fluid transfused, and duration of postreperfusion syndrome were independent risk factors for ALI after LDLT in pediatric patients ( P<0.05). The area under the receiver operating characteristic curve of the preoperative N-terminal pro-brain natriuretic peptide(NT-pro-BNP) concentration in predicting postoperative ALI was 0.737 ( P<0.001), with a cutoff value of 222.1 ng/L, sensitivity of 0.628, and specificity of 0.732. Conclusions:Preoperative pediatric end-stage liver disease score, serum NT-pro-BNP concentrations, intraoperative volume of fluid transfused, and duration of postreperfusion syndrome are independent risk factors for ALI after LDLT in pediatric patients; preoperative serum NT-pro-BNP concentrations can effectively predict the development of ALI after pediatric LDLT surgery.

Objective:To evaluate the effect of stroke volume variation(SVV) goal-directed fluid therapy on postoperative pulmonary complications(PPCs) after pediatric living donor liver transplantation.Methods:One hundred and twenty pediatric patients undergoing pediatric living-donor liver transplantation(all diagnosed with congenital biliary atresia) were divided into 2 groups( n=60 each) using the random number table method: control group and SVV group. Intraoperative fluid management was guided by central venous pressure and mean arterial pressure in control group, while by SVV combined with cardiac output in SVV group. Intraoperative circulation, fluid intake and usage of vasoactive drug were recorded. Central venous blood samples were collected to determine the concentrations of serum Clara cell 16 kDa protein, interleukin-6, and tumor necrosis factor-alpha before anesthesia(T 0), at the end of anhepatic phase(T 1), at 3 h of neohepatic phase(T 2), at the end of surgery(T 3) and at 24 h after operation(T 4). Pulmonary ultrasonography was performed before surgery, at the end of surgery and at 1, 3 and 7 days after surgery. The pediatric patients were followed up for 1 week after surgery to record the PPCs, including acute lung injury, pulmonary infection, pulmonary atelectasis, pleural effusion and acute respiratory distress syndrome. Results:Compared with control group, the incidence of PPCs, acute lung injury and pulmonary infection was significantly decreased, the pulmonary ultrasound score was decreased at the end of surgery and at 1, 3 and 7 days after surgery, the usage of intraoperative dobutamine was increased, the duration of postreperfusion syndrome was shortened, the fluid intake and epinephrine usage were reduced, and the serum Clara cell 16 kDa protein, tumor necrosis factor-alpha and interleukin-6 concentrations were decreased at T 1-T 4 in SVV group( P<0.05). Conclusions:SVV goal-directed fluid management can reduce the development of PPCs in pediatric living donor liver transplantation.

Objective:To explore the effect of intensive insulin therapy on hemodynamics and cardiac function in organ donors.Methods:A total of 60 organ donors were randomly divided into two groups of intensive insulin therapy(IIT)and control(30cases each group). Blood glucose was adjusted at 6.2~10.0 mmol/L in control group and 4.4~6.1 mmol/L in IIT group.Blood glucose and insulin dosage during maintenance were recorded.Cardiac function values as well as serum inflammatory factor concentrations at admission and during donation were compared between two groups.Results:During maintenance, blood glucose was significantly lower in IIT group than that in control group [(5.1±0.6)vs(8.2±1.5)mmol/L, P<0.05] and insulin dosage was higher than that in control group [(9.5±3.2)vs(5.8±1.5)U/h, P<0.05]. As compared with control group, cardiac cycle efficiency(CCE), maximal rate of elevated pressure(DP/DT max)and left ventricular ejection fraction(LVEF)in were significantly higher in IIT group than those of control group.And serum cardiac troponin I(cTnI), N-terminal B-type natriuretic peptide(NT-Pro-BNP), interleukin-6(IL-6), tumor necrosis factor-α(TNF-α)and high mobility group box-1 protein(HMGB1)as well as vasoactive-inotropic score(VIS)were significantly lower than those in control group( P<0.05). As compared with control group, cardiac donation rate of IIT group was significantly higher(30% vs 16.7%, P<0.05). Conclusions:Intensive insulin therapy and blood glucose control may blunt inflammatory response in organ donors, lessen myocardial injury and myocardial depression, stabilize hemodynamics and boost the rate of cardiac donation.
