Objective:To investigate the value of systemic inflammatory response syndrome (SIRS), pediatric sequential organ failure assessment (pSOFA) and pediatric critical illness score (PCIS) in predicting mortality of pediatric sepsis in pediatric intensive care units (PICU) from Southwest China.Methods:This was a prospective multicenter observational study. A total of 447 children with sepsis admitted to 12 PICU in Southwest China from April 2022 to March 2023 were enrolled. Based on the prognosis, the patients were divided into survival group and non-survival group. The physiological parameters of SIRS, pSOFA and PCIS were recorded and scored within 24 h after PICU admission. The general clinical data and some laboratory results were recorded. The area under the curve (AUC) of the receiver operating characteristic curve was used to compare the predictive value of SIRS, pSOFA and PCIS in mortality of pediatric sepsis.Results:Amongst 447 children with sepsis, 260 patients were male and 187 patients were female, aged 2.5 (0.8, 7.0) years, 405 patients were in the survival group and 42 patients were in the non-survival group. 418 patients (93.5%) met the criteria of SIRS, and 440 patients (98.4%) met the criteria of pSOFA≥2. There was no significant difference in the number of items meeting the SIRS criteria between the survival group and the non-survival group (3(2, 4) vs. 3(3, 4) points, Z=1.30, P=0.192). The pSOFA score of the non-survival group was significantly higher than that of the survival group (9(6, 12) vs. 4(3, 7) points, Z=6.56, P<0.001), and the PCIS score was significantly lower than that of the survival group (72(68, 81) vs. 82(76, 88) points, Z=5.90, P<0.001). The predictive value of pSOFA (AUC=0.82) and PCIS (AUC=0.78) for sepsis mortality was significantly higher than that of SIRS (AUC=0.56) ( Z=6.59, 4.23, both P<0.001). There was no significant difference between pSOFA and PCIS ( Z=1.35, P=0.176). Platelet count, procalcitonin, lactic acid, albumin, creatinine, total bilirubin, activated partial thromboplastin time, prothrombin time and international normalized ratio were all able to predict mortality of sepsis to a certain degree (AUC=0.64, 0.68, 0.80, 0.64, 0.68, 0.60, 0.77, 0.75, 0.76, all P<0.05). Conclusion:Compared with SIRS, both pSOFA and PCIS had better predictive value in the mortality of pediatric sepsis in PICU.

Background Air pollution is a major public health concern. Air Quality Health Index (AQHI) is a very important air quality risk communication tool. However, AQHI is usually constructed by single-pollutant model, which has obvious disadvantages. Objective To construct an AQHI based on the joint effects of multiple air pollutants (J-AQHI), and to provide a scientific tool for health risk warning and risk communication of air pollution. Methods Data on non-accidental deaths in Yunnan, Guangdong, Hunan, Zhejiang, and Jilin provinces from January 1, 2013 to December 31, 2018 were obtained from the corresponding provincial disease surveillance points systems (DSPS), including date of death, age, gender, and cause of death. Daily meteorological (temperature and relative humidity) and air pollution data (SO₂, NO₂, CO, PM_2.5, PM₁₀, and maximum 8 h O₃ concentrations) at the same period were respectively derived from China Meteorological Data Sharing Service System and National Urban Air Quality Real-time Publishing Platform. Lasso regression was first applied to select air pollutants, then a time-stratified case-crossover design was applied. Each case was matched to 3 or 4 control days which were selected on the same days of the week in the same calendar month. Then a distributed lag nonlinear model (DLNM) was used to estimate the exposure-response relationship between selected air pollutants and mortality, which was used to construct the AQHI. Finally, AQHI was classified into four levels according to the air pollutant guidance limit values from World Health Organization Global Air Quality Guidelines (AQG 2021), and the excess risks (ERs) were calculated to compare the AQHI based on single-pollutant model and the J-AQHI based on multi-pollutant model. Results PM_2.5, NO₂, SO₂, and O₃ were selected by Lasso regression to establish DLNM model. The ERs for an interquartile range (IQR) increase and 95% confidence intervals (CI) for PM_2.5, NO₂, SO₂ and O₃ were 0.71% (0.34%–1.09%), 2.46% (1.78%–3.15%), 1.25% (0.9%–1.6%), and 0.27% (−0.11%–0.65%) respectively. The distribution of J-AQHI was right-skewed, and it was divided into four levels, with ranges of 0-1 for low risk, 2-3 for moderate risk, 4-5 for high health risk, and ≥6 for severe risk, and the corresponding proportions were 11.25%, 64.61%, 19.33%, and 4.81%, respectively. The ER (95%CI) of mortality risk increased by 3.61% (2.93–4.29) for each IQR increase of the multi-pollutant based J-AQHI , while it was 3.39% (2.68–4.11) for the single-pollutant based AQHI . Conclusion The J-AQHI generated by multi-pollutant model demonstrates the actual exposure health risk of air pollution in the population and provides new ideas for further improvement of AQHI calculation methods.

Objective:To explore the effect of teach-back method combined with follow-up nursing on the adherence of glucocorticoid medication in patients with uveitis.Methods:From July to December 2021, 243 patients with uveitis admitted to the Department of Ophthalmology of the First Affiliated Hospital of Zhengzhou University were selected as the study subject by convenience sampling. A total of 120 patients admitted from July to September 2021 were set as the control group, and 123 patients admitted from October to December 2021 were set as the intervention group. The control group received routine medication guidance and follow-up nursing, while the intervention group received medication guidance and follow-up nursing using the teach-back method. The adherence of two groups of patients to glucocorticoid medication before and three months after intervention were compared.Results:Before intervention, there was no statistically significant difference in medication adherence between the two groups of patients ( Z=-0.382, P=0.702). After intervention, the medication adherence of the intervention group patients was better than that of the control group, with a statistically significant difference ( Z=-8.854, P<0.001) . Conclusions:The combination of teach-back method and follow-up nursing can effectively improve the adherence of patients with uveitis to glucocorticoid medication.

Peutz-Jeghers syndrome (PJS) presents in early childhood, and children have a higher risk of intussusception due to a smaller abdominal space than adults. Double-balloon enteroscopy (DBE) has been proven to be a safe and effective method for the diagnosis and treatment of small bowel lesions, but the efficacy and safety of its prophylactic polypectomy in children with PJS need to be determined. Data of 6 children (median age 10.6 years) diagnosed as having PJS from 2018 to 2020 were reviewed. DBE was performed 14 times, and 3 children were successfully relieved of intussusception after DBE treatment. The sizes of the resected intussusception polyps were 50 mm×60 mm, 40 mm×35 mm, and 50 mm×40 mm. Symptoms associated with polyps (abdominal pain, intussusception and obstruction) relieved after DBE in all children. No direct complications such as bleeding or perforation were found during the operation, and no recurrence of intussusception was found during follow-up. It can be seen that DBE polypectomy is safe and effective in the treatment of intussusception caused by PJS.

Objective:To study the predictors of postpartum hepatitis in pregnant women with chronic HBV infection.Methods:In this retrospective study, liver function and hepatitis B virology tests of pregnant women with chronic HBV infection at delivery and within 48 weeks were collected from the clinical medical system after the enrollment of eligible patients. Statistical analysis was performed on the obtained data.Results:A total of 533 pregnant women meeting the criteria were enrolled, and the average age of all patients was 29.5±3.7. A total of 408 pregnant women took antiviral drugs during pregnancy for prevention of mother-to-child transmission; 231 patients developed hepatitis within 1 year after delivery. There were significant differences in alanine transaminase (ALT), aspartate transaminase (AST), HBV DNA during delivery, hepatitis B e antigen (HBeAg) during delivery and baseline HBeAg between patients with and without hepatitis. Multivariate binary logistic regression analysis showed that HBeAg ( OR=0.19, 0.074-0.473; P<0.001), ALT ( OR=1.05, 1.021-1.071; P<0.001), albumin ( OR=0.91, 0.833-0.995; P=0.038), platelet ( OR=0.995, 0.992-0.999; P=0.01), neutrophils ( OR=0.98, 0.973-0.995; P=0.004) had significant difference. Conclusions:Baseline HBeAg and ALT are powerful predictors of postpartum hepatitis in pregnant women with chronic HBV infection.

Objective: To discuss the application of bedside ultrasound monitoring of gastric residual volume in ICU patients complicated with enteral nutrition support via nasogastric tube. Methods: November 2017 to May 2018, 120 patients with enteral nutrition support via nasogastric tube who admitted in ICU of our hospital were randomly divided into the observation group and the control group. The observation group used bedside ultrasound monitoring to determine the gastric residual volume, while the control group was estimated by withdrawn with 50 ml syringe. Reflux, pulmonary aspiration and the time of enteral nutrition were observed in both groups. Results: Reflux and pulmonary aspiration were present in 2, 3 in the observation group and 10, 11 in the control group, with significant difference between them (χ²=4.53, 3.96, P<0.05). The time of enteral nutrition in the observation group was (13.98±3.20) h, and (15.54±3.54) h in the control group, which had a statistically difference (t=-10.49, P<0.05). Conclusion The application of bedside ultrasound monitoring of gastric residual volume in ICU patients complicated with enteral nutrition support via nasogastric tube can significantly reduce the risk of reflux and pulmonary aspiration which can ensure the safety of enteral nutrition, and decrease time of enteral nutrition.

Objective: To evaluate the efficacy and safety of compound Lactobacillus acidophilus tablets or Saccharomyces boulardii Sachets combined with standard protocols for eradication of Helicobacter pylori(Hp) in children. Methods: From March 2017 to March 2018, 120 children aged 3-10 years with Hp infection were admitted into the Department of Gastroenterology, Maternal and Child Health Hospital of Hubei Province, including 67 male and 53 female childen.They were divided into 3 groups (control group, compound Lactobacillus acidophilus group, Saccharomyces boulardii Sachets group) by the method of random number table.Control group was given Clarithromycin+ Amoxicillin+ Omeprazole, for 14 days orally; compound Lactobacillus acidophilus group and Saccharomyces boulardii Sachets group were given drugs respectively on the first day, 500 mg of compound Lactobacillus acidophilus was added, twice a day or 250 mg of Saccharomyces boulardii Sachets group, twice a day orally, for 14 days, respectively.The adverse reactions in children were observed during the treatment, andurea ¹³C breath test or the stool Hp antigen test was performed at least 4 weeks by the end of the treatment, and the children with negative results were judged to be eradicated successfully.The ulcer healing, Hp eradication rate and incidence of adverse reactions(nausesa, vomiting, loss of appetite, constipation, diarrhea) among the 3 groups were observed and the Hp eradication rate and the incidence of adverse reactions (nausea, vomiting, loss of appetite, constipation, diarrhea) were compared. Results: The eradication rates in the control group, the compound Lactobacillus group, and Saccharomyces boulardii Sachets group were 80.0% (32/40 cases), 85.0% (34/40 cases), and 87.5% (35/40 cases), respectively, and the difference was not statistically significant (P=0.646); the ulcer healing rate was 100.0% of 101 Hp eradicators in 3 groups, and the ulcer healing rate of 19 cases without Hp eradicated was 48.15%, and there was a significant difference between them (χ²=51.30, P<0.01). However, there was no significant difference in the total effective rate among 3 groups (P>0.05). The overall incidence of adverse reactions in Saccharomyces boulardii Sachets group (P=0.021) and the incidence of diarrhea (P=0.002) and loss of appetite (P=0.021) was lower than that in the control group, and the differences were statistically significant.There was no significant difference in the incidence of adverse reactions between the two probiotic groups (P>0.05). Conclusions Both compound Lactobacillus acidophilus tablets and Saccharomyces boulardii Sachets group can reduce the overall incidence of adverse reactions and the incidence of diarrhea and appetite declines in children′s standard Hp eradication regimen without affecting Hp eradication rate.
