Objective:To investigate respiratory virus infection in children with septic shock in pediatric care units (PICU) in China and its influence on clinical outcomes.Methods:The clinical data of children with septic shock in children′s PICU from January 2018 to December 2019 in 10 Chinese hospitals were retrospectively collected. They were divided into the pre-COVID-19 and post-COVID-19 groups according to the onset of disease, and the characteristics and composition of respiratory virus in the 2 groups were compared. Matching age, malignant underlying diseases, bacteria, fungi and other viruses, a new database was generated using 1∶1 propensity score matching method. The children were divided into the respiratory virus group and non-respiratory virus group according to the presence or absence of respiratory virus infection; their clinical characteristics, diagnosis, and treatment were compared by t-test, rank sum test and Chi-square test. The correlation between respiratory virus infection and the clinical outcomes was analyzed by logistic regression. Results:A total of 1 247 children with septic shock were included in the study, of them 748 were male; the age was 37 (11, 105) months. In the pre-and post-COVID-19 groups, there were 530 and 717 cases of septic shock, respectively; the positive rate of respiratory virus was 14.9% (79 cases) and 9.8% (70 cases); the seasonal distribution of septic shock was 28.9% (153/530) and 25.9% (185/717) in autumn, and 30.3% (161/530) and 28.3% (203/717) in winter, respectively, and the corresponding positive rates of respiratory viruses were 19.6% (30/153) and 15.7% (29/185) in autumn, and 21.1% (34/161) and 15.3% (31/203) in winter, respectively. The positive rates of influenza virus and adenovirus in the post-COVID-19 group were lower than those in the pre-COVID-19 group (2.1% (15/717) vs. 7.5% (40/530), and 0.7% (5/717) vs. 3.2% (17/530), χ2=21.51 and 11.08, respectively; all P<0.05). Rhinovirus virus were higher than those in the pre-Covid-19 group (1.7% (12/717) vs. 0.2% (1/530), χ2=6.51, P=0.011). After propensity score matching, there were 147 cases in both the respiratory virus group and the non-respiratory virus group. Rate of respiratory failure, acute respiratory distress, rate of disseminated coagulation dysfunction, and immunoglobulin usage of the respiratory virus group were higher than those of non-respiratory virus group (77.6% (114/147) vs. 59.2% (87/147), 17.7% (26/147) vs. 4.1% (6/147), 15.6% (25/147) vs. 4.1% (7/147), and 35.4% (52/147) vs. 21.4% (32/147); χ2=11.07, 14.02, 11.06 and 6.67, all P<0.05); and PICU hospitalization of the former was longer than that of the later (7 (3, 16) vs. 3 (1, 7)d, Z=5.01, P<0.001). Univariate logistic regression analysis showed that the presence of respiratory viral infection was associated with respiratory failure, disseminated coagulation dysfunction, the use of mechanical ventilation, and the use of immunoglobulin and anti-respiratory viral drugs ( OR=2.42, 0.22, 0.25, 0.56 and 1.12, all P<0.05). Conclusions:The composition of respiratory virus infection in children with septic shock is different between pre and post-COVID-19. Respiratory viral infection is associated with organ dysfunction in children with septic shock. Decreasing respiratory viral infection through respiratory protection may improve the clinical outcome of these children.

Objective:To investigate the clinical features, pathogen composition, and prognosis of septic shock in pediatric intensive care units (PICU) in China.Methods:A multicenter retrospective cohort study. A retrospective analysis was conducted on the clinical data of children with septic shock from 10 hospitals in China between January 2018 and December 2021. The clinical features, pathogen composition, and outcomes were collected. Patients were categorized into malignant tumor and non-malignant tumor groups, as well as survival and mortality groups. T test, Mann Whitney U test or Chi square test were used respectively for comparing clinical characteristics and prognosis between 2 groups. Multiple Logistic regression was used to identify risk factors for mortality. Results:A total of 1 247 children with septic shock were included, with 748 males (59.9%) and the age of 3.1 (0.9, 8.8) years. The in-patient mortality rate was 23.2% (289 cases). The overall pathogen positive rate was 68.2% (851 cases), with 1 229 pathogens identified. Bacterial accounted for 61.4% (754 strains) and virus for 24.8% (305 strains). Among all bacterium, Gram negative bacteria constituted 64.2% (484 strains), with Pseudomonas aeruginosa and Enterobacter being the most common; Gram positive bacteria comprised 35.8% (270 strains), primarily Streptococcus and Staphylococcus species. Influenza virus (86 strains (28.2%)), Epstein-Barr virus (53 strains (17.4%)), and respiratory syncytial virus (46 strains (17.1%)) were the top three viruses. Children with malignant tumors were older and had higher pediatric risk of mortality (PRISM) Ⅲ score, paediatric sequential organ failure assessment (pSOFA) score (7.9 (4.3, 11.8) vs. 2.3 (0.8, 7.5) years old, 22 (16, 26) vs. 16 (10, 24) points, 10 (5, 14) vs. 8 (4, 12) points, Z=11.32, 0.87, 4.00, all P<0.05), and higher pathogen positive rate, and in-hospital mortality (77.7% (240/309) vs. 65.1% (611/938), 29.7% (92/309) vs. 21.0% (197/938), χ2=16.84, 10.04, both P<0.05) compared to the non-tumor group. In the death group, the score of PRISM Ⅲ, pSOFA (16 (22, 29) vs. 14 (10, 20) points, 8 (12, 15) vs. 6 (3, 9) points, Z=4.92, 11.88, both P<0.05) were all higher, and presence of neoplastic disease, positive rate of pathogen and proportion of invasive mechanical ventilation in death group were also all higher than those in survival group (29.7% (87/289) vs. 23.2% (222/958), 77.8% (225/289) vs. 65.4% (626/958), 73.7% (213/289) vs. 50.6% (485/958), χ2=5.72, 16.03, 49.98, all P<0.05). Multiple Logistic regression showed that PRISM Ⅲ, pSOFA, and malignant tumor were the independent risk factors for mortality ( OR=1.04, 1.09, 0.67, 95% CI 1.01-1.05, 1.04-1.12, 0.47-0.94, all P<0.05). Conclusions:Bacterial infection are predominant in pediatric septic shock, but viral infection are also significant. Children with malignancies are more severe and resource consumptive. The overall mortality rate for pediatric septic shock remains high, and mortality are associated with malignant tumor, PRISM Ⅲ and pSOFA scores.

Objective:To explore the application of step-by-step mentorship combined with individualized assessment in practical nursing skill training in higher vocational colleges.Methods:A total of 219 nursing students of Class 2020 were selected from a higher vocational college; they were randomly divided into control group (107 students) and experimental group (112 students), both of which were offered nursing training courses in the first semester. The control group was offered conventional teaching, while the experimental group was offered step-by-step mentorship combined with individualized assessment. The two groups were compared for post-training assessment scores of theoretical knowledge and practical skills and pre-training and post-training comprehensive nursing ability as well as their recognition of the teaching methods after training. The t-test and chi-square test were performed using SPSS 22.0. Results:The post-training assessment scores of theoretical knowledge and practical skills were significantly higher in both subitem score [(89.68±3.58) vs. (82.56±3.35)] and total score [(91.75±3.01) vs. (85.36±2.58)] in the experimental group than in the control group ( P<0.05). There were no significant differences in pre-training comprehensive nursing ability between the two groups, while the post-training comprehensive nursing ability scores were significantly higher in both subitem score and total score [(86.53±2.61) vs. (80.32±2.31)] in the experimental group than in the control group ( P<0.05). After the training, students in the experimental group showed increased recognition of the teaching methods in stimulating their learning interest and initiative, improving their self-learning ability, improving their comprehensive literacy, improving their ability to apply theoretical knowledge, and improving their clinical thinking ability compared with the control group ( P<0.05). Conclusion:The application of step-by-step mentorship combined with individualized assessment in practical nursing skill training in higher vocational colleges can improve students' academic performance and comprehensive nursing ability and increase their recognition of the teaching methods, thus making it worthwhile to be widely adopted.

Objective:To compare the efficacy of endoscopy and surgery in chronic pancreatitis.Methods:CNKI, CBM, Wanfang, PubMed, Cochrane Library, Embase and Web of Science were searched to compared endoscopy and surgery for the clinical efficacy of chronic pancreatitis. Literatures were searched from the establishment of the database to August 14, 2022. Compared pain relief, clinical response to initial treatment, complications, endocrine/exocrine insufficiency, length of hospital stay and mean number of procedures between the two groups. Manager 5.4.1 software was used for data analysis. Odds ratio ( OR) or weighted mean difference ( WMD) was calculated with 95% confidence interval (95% CI). Results:A total of seven studies were included, including three randomized controlled trials and four retrospective studies with 708 patients. There were 513 males and 195 females. Endoscopic interventions were performed in 364 patients and 344 patients underwent surgery. The results of meta-analysis showed that the total pain relief rate ( OR=0.38, 95% CI: 0.24-0.59) and the complete pain relief rate ( OR=0.47, 95% CI: 0.29-0.77), short-term (1-1.5 years) pain relief rate ( OR=0.42, 95% CI: 0.24-0.74), clinical relief rate ( OR=0.23, 95% CI: 0.10-0.55) were better than the endoscopic group, and could significantly reduce the number of reoperation ( WMD=1.64, 95% CI: 0.89-2.40), and the difference was statistically significant (all P<0.05). There were no significant differences in complications, new-onset endocrine insufficiency, new-onset exocrine insufficiency and length of hospital stay between the endoscopy group and the surgical group (all P>0.05). Conclusion:Surgical intervention is superior to endoscopic treatment in controlling pain associated with chronic pancreatitis and in clinical relief after the first treatment, and can effectively reduce the number of reoperations.

Objective:To analyze the risk factors for postoperative delirium in patients with glioma, and construct and validate a nomogram prediction model.Methods:A total of 304 glioma surgery patients admitted to the Department of Neurosurgery of Shandong Provincial Hospital from January 2021 to January 2022 were involved in this research. The training set (234 patients) and the validation set (70 patients) were divided according to the leave-out method. Patients in the training set and validation set were divided into delirium and non-delirium groups using the confusion assessment method (CAM) as the criteria.Clinical data of patients in the two study groups in the training set were analyzed.The risk factors for postoperative delirium were clarified by Logistic regression analysis, and an early warning model for postoperative delirium in glioma was established. The calibration curve and ROC curve were used for internal and external validation in the training set and validation set to evaluate the accuracy and discrimination of the prediction model.Results:Multivariate Logistic regression analysis showed that age>60 ( OR=4.089, 95% CI=1.898-9.103, P<0.001), diabetes ( OR=2.825, 95% CI=1.316-6.186, P=0.008), hypertension ( OR=2.176, 95% CI=1.041-4.587, P=0.008), smoking ( OR=2.432, 95% CI=1.063-5.648, P=0.036), history of epileptic seizures ( OR=4.457, 95% CI=1.924-10.689, P=0.001), poor lung function ( OR=2.452, 95% CI=1.132-5.374, P=0.023), visual analog scale (VAS)>7 points ( OR=3.394, 95% CI=1.591-7.456, P=0.002), anxiety or depression ( OR=2.746, 95% CI=1.285-5.976, P=0.010) and operation duration>4 h ( OR=2.731, 95% CI=1.255-6.062, P=0.012) were the independent risk factors of brain glial postoperative delirium.Based on the above risk factors a nomogram nursing early warning model was established.The area under the ROC curve (AUC) of internal verification was 0.852, and AUC of external verification was 0.914. Conclusion:The early-warning model for postoperative delirium in glioma patients can effectively predict the risk of delirium after glioma surgery, and it has certain clinical promotion value.

Objective:To explore the effects of interpregnancy interval (IPI) on pregnancy outcomes of subsequent pregnancy.Methods:A multicenter retrospective study was conducted in 21 hospitals in China. Information of age, height, pre-pregnancy weight, IPI, history of diseases, complications of pregnancy, gestational age of delivery, delivery mode, and pregnancy outcomes of the participants were collected by consulting medical records of pregnant women who had two consecutive deliveries in the same hospital during 2011 to 2018. The participants were divided into 4 groups according to IPI:<18 months, 18-23 months, 24-59 months and ≥60 months. According to the WHO′s recommendation, with the IPI of 24-59 months group as a reference, to the effects of IPI on pregnancy outcomes of subsequent pregnancy were analyzed. Stratified analysis was further carried out based on age, history of gestational diabetes mellitus (GDM), macrosomia, and premature delivery, to explore the differences in the effects of IPI on pregnancy outcomes among women with different characteristics.Results:A total of 8 026 women were included in this study. There were 423, 623, 5 512 and 1 468 participants in <18 months group, 18-23 months group, 24-59 months group and ≥60 months group, respectively. (1) The age, pre-pregnancy body mass index (BMI), history of cesarean section, GDM, gestational hypertension and cesarean section delivery rate of <18 months group, 18-23 months group, 24-59 months group and ≥60 months group were gradually increased, and the differences were statistically significant ( P<0.05). (2) After adjusting for potential confounding factors, compared with women in the IPI of 24-59 months group, the risk of premature delivery, premature rupture of membranes, and oligohydramnios were increased by 42% ( OR=1.42, 95% CI: 1.07-1.88, P=0.015), 46% ( OR=1.46, 95% CI: 1.13-1.88, P=0.004), and 64% ( OR=1.64, 95% CI: 1.13-2.38, P=0.009) respectively for women in the IPI≥60 months group. No effects of IPI on other pregnancy outcomes were found in this study ( P>0.05). (3) After stratified by age and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of oligohydramnios for women with advanced age ( OR=2.87, 95% CI: 1.41-5.83, P=0.004); and <18 months could increase the risk of premature rupture of membranes for women under the age of 35 ( OR=1.59, 95% CI: 1.04-2.43, P=0.032). Both the risk of premature rupture of membranes ( OR=1.58, 95% CI: 1.18-2.13, P=0.002) and premature delivery ( OR=1.52, 95% CI: 1.07-2.17, P=0.020) were significantly increased in the IPI≥60 months group. After stratified by history of GDM and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would lead to an increased risk of postpartum hemorrhage for women with a history of GDM ( OR=5.34, 95% CI: 1.45-19.70, P=0.012) and an increased risk of premature rupture of membranes for women without a history of GDM ( OR=1.44, 95% CI: 1.10-1.90, P=0.009). After stratified by history of macrosomia and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months could increase the proportion of cesarean section for women with a history of macrosomia ( OR=4.11, 95% CI: 1.18-14.27, P=0.026) and the risk of premature rupture of membranes for women without a history of macrosomia ( OR=1.46, 95% CI: 1.12-1.89, P=0.005). After stratified by history of premature delivery and adjusted for confounding factors, compared with women in the IPI of 24-59 months group, IPI≥60 months would significantly increase the risk of premature rupture of membranes for women without a history of premature delivery ( OR=1.47, 95% CI: 1.13-1.92, P=0.004). Conclusions:Both IPI≥60 months and <18 months would increase the risk of adverse pregnancy outcomes in the subsequent pregnancy. Healthcare education and consultation should be conducted for women of reproductive age to maintain an appropriate IPI when they plan to pregnant again, to reduce the risk of adverse pregnancy outcomes in the subsequent pregnancy.

Objective:To explore the effect of breathing exercises on motor, balance, respiration and ability in the activities of daily living (ADL) of patients with Parkinson′s disease.Methods:Sixty patients with idiopathic Parkinson′s disease who met the inclusion criteria were divided at random into a control group and a treatment group, each of 30. Both groups received routine drug therapy and 60 minute of rehabilitation training daily, including core muscle group control training, relaxation training, joint motion training, posture training, balance function training, gait training and facial muscle control training. There were 3 sessions a week for 24 weeks. The treatment group was also given breathing exercises, including training in abdominal breathing with the expiration time twice the inspiration time and inspiratory muscle training. The abdominal breathing training included 15 abdominal breaths, repeated twice after a 2-minute break; the inspiratory muscle training required 10 respirations and expirations at the maximum volume, repeated twice after an interval of 2 minutes. The training lasted 24 weeks, five times a week. The subjects′ motor functioning, balance, walking, respiration and daily living ability were evaluated before the treatment and after 12 and 24 weeks of treatment using the Parkinson′s Disease Rating Scale (part III) (UPDRS ⅲ), the Berg Balance Scale (BBS), the 6-minute walk test (6MWT), walking distance and the modified Barthel Index (MBI). Forced expiratory volume in the first second (FEV 1), forced vital capacity (FVC) and their ratio (FEV 1%) were also observed. Results:After 12 weeks of treatment, significant improvement was observed in the average UPDRS iii, BBS, 6MWT, MBI, FEV 1, FVC and FEV 1% results of both groups, but the improvement in the treatment group was significantly greater on average. After another twelve week the average UPDRS iii, BBS, 6MWT, MBI, FEV 1, FVC and FEV 1% results of the treatment group had improved significantly more than those of the control group. Conclusion:Breathing exercises can significantly improve the motor function, balance, walking, respiratory function and ADL ability of persons with Parkinson′s disease.

Objective:To design an infection control culture assessment scale to comprehensively assess a hospital in general.Methods:Based on the American mature safety culture survey scale(HSOPSC), we developed an infection control culture assessment scale. With this scale, a cross-sectional study was conducted to survey 684 medical staff between October 2018 to January 2019. 607 valid questionnaires were recovered. Reliability and validity of the assessment were then examined by Delphi method, Exploratory factor analysis and confirmatory factor analysis, while the positive response ratio of the dimension was calculated.Results:The scale of infection control culture assessment included 30 entries and 7 factors with eigenvalue>1, and a cumulative variance contribution rate of 57.97%. The 7 factors were basic infection control ability, hospital management atmosphere, mutual support between coworkers, reporting of negative events, interdepartmental collaboration, organizational learning and continuous improvement and working load. Cronbach′s coefficient of the entire assessment was 0.909, and split-half reliability was 0.941. Confirmatory factor analysis showed GFI, CFI, RMSEA, IFI, AGFI and other indicators were better fitted. Among all the factors, the organizational learning and continuous improvement and working load were lower than 50%, which should to be improved for the infection control culture. Conclusions:The assessment scale proved good reliability and validity, which may be widely used in hospitals. Regular measurement and improvement could effectively improve the infection control awareness of medical staff and ensure medical quality.

Objective:Based on a cross-sectional survey about the status of analgesia and sedation nursing behavior of PICU nurses in Northeast China and Inner Mongolia, to analyze the influencing factors and to provide reference for further constructing standardized training programs and developing standardized for analgesia and sedation nursing process.Methods:The self-designed questionnaire was made for investigation from 435 PICU nurses in 18 hospitals in Northeast China and Inner Mongolia.Results:The average questionnaire score of the analgesia and sedation nursing behavior of PICU nurses was(70.54±13.63)in Northeast China and Inner Mongolia.The behavioral scores were different in each group between different age, nursing age, PICU nursing age, educational background, professional title, and whether was the intensive care unit nurse, whether trained in analgesia and sedation, whether have experience in caring children with analgesia and sedation, and the differences were all statistically significant( P<0.05). The main factors influencing the analgesia and sedation behavior of PICU nurses were whether have received training in analgesia and sedation, whether have experience in caring children with analgesia and sedation treatment and their attitude score to analgesia and sedation. Conclusion:There is still much space for development in analgesia and sedation nursing behavior of PICU nurses in Northeast China and Inner Mongolia.The more analgesia and sedation training PICU nurses take participate in, the more experience and positive attitudes they have in nursing children with analgesia and sedation, their clinical nursing practice ability could become more stronger.

Objective:To explore the effect of subclinical hypothyroidism(SCH) on complications after coronary artery bypass grafting(CABG).Methods:The data of CABG patients hospitalized in TEDA International Cardiovascular Disease Hospital from January 2016 to December 2017 were retrospectively analyzed. According to the thyroid function after admission, the patients were divided into normal thyroid function group(NC group, 814 cases, 0.27 mIU/L≤TSH≤4.2 mIU/L) and subclinical hypothyroidism group(SCH group, 106 cases, TSH>4.2 mIU/L). The preoperative clinical data, surgical conditions, recent complications and one-year bridge stenosis rate were compared between the two groups in male or female.Results:Compared with NC group, SCH group had more female patients(53.8% vs 24.4%, P=0.000), lower smoking rate (38.7% vs 58.0%, P=0.000). There was no statistical difference in other baseline data and postoperative complications( P>0.05). Subgroup analysis depending on gender showed that the incidence of respiratory tract infection increased in female patients with SCH(10.5% vs 3.5%, P=0.034) compared with those in NC group, there was no significant difference in male. The TSH level was an independent risk factor for respiratory tract infection in female patients( OR=1.307, 95% CI=1.110-1.539, P=0.001). Compared with the male patients, the prevalence of hypertension(84.2% vs. 67.3%, P=0.041), diabetes mellitus(45.6% vs 16.3%, P=0.001), hospitalization time in ICU(44 h vs. 42 h, P=0.003), acute renal failure(10.5% vs 0, P=0.019) and massive blood transfusion(8.8% vs 0, P=0.034)increased. Conclusion:SCH appears to influence the postoperative outcome for female patients by increasing the development of postoperative respiratory tract infection.
