A nomogram for predicting hemorrhagic shock in pediatric patients with multiple trauma.

The timely detection and management of hemorrhagic shock hold paramount importance in clinical practice. This study was designed to establish a nomogram that may facilitate early identification of hemorrhagic shock in pediatric patients with multiple-trauma. A retrospective study was conducted utilizing a cohort comprising 325 pediatric patients diagnosed with multiple-trauma, who received treatment at the Children's Hospital, Zhejiang University School of Medicine, Zhejiang, China. For external validation, an additional cohort of 144 patients from a children's hospital in Taizhou was included. The model's predictor selection was optimized through the application of the Least Absolute Shrinkage and Selection Operator (LASSO) regression. Subsequently, a prediction nomogram was constructed using multivariable logistic regression analysis. The performance and clinical utility of the developed model were comprehensively assessed utilizing various statistical metrics, including Harrell's Concordance Index (C-index), receiver operating characteristic (ROC) curve analysis, calibration curve analysis, and decision curve analysis (DCA). Multivariate logistic regression analysis identified systolic blood pressure (ΔSBP), platelet count, activated partial thromboplastin time (APTT), and injury severity score (ISS) as independent predictors for hemorrhagic shock. The nomogram constructed using these predictors demonstrated robust predictive capabilities, as evidenced by an impressive area under the curve (AUC) value of 0.963. The model's goodness-of-fit was assessed using the Hosmer-Lemeshow test (χ2 = 10.023, P = 0.209). Furthermore, decision curve analysis revealed significantly improved net benefits with the model. External validation further confirmed the reliability of the proposed predictive nomogram. This study successfully developed a nomogram for predicting the occurrence of hemorrhagic shock in pediatric patients with multiple trauma. This nomogram may serve as an accurate and effective tool for timely and efficient management of children with multiple trauma.

Association between pediatric postoperative delirium and regional cerebral oxygen saturation: a prospective observational study.

BACKGROUND: Postoperative delirium (POD) represents a prevalent and noteworthy complication in the context of pediatric surgical interventions. In recent times, a hypothesis has emerged positing that cerebral ischemia and regional cerebral oxygen desaturation might serve as potential catalysts in the pathogenesis of POD. The primary aim of this study was to methodically examine the potential relationship between POD and regional cerebral oxygen saturation (rSO2) and to assess the predictive and evaluative utility of rSO2 in the context of POD. METHODS: This prospective observational study was conducted at the Children's Hospital, Zhejiang University School of Medicine, Zhejiang, China, spanning the period from November 2020 to March 2021. The research cohort comprised children undergoing surgical procedures within this clinical setting. To measure rSO2 dynamics, cerebral near-infrared spectroscopy (NIRS) was used to monitor rSO2 levels both before and after surgery. In addition, POD was assessed in the paediatric patients according to the Diagnostic and Statistical Manual of Mental Disorders Fifth Edition (DSM-5) criteria. The analysis of the association between the rSO2 index and the incidence of POD was carried out through the application of either the independent samples t-test or the nonparametric rank-sum test. To ascertain the threshold value of the adjusted rSO2 index for predictive and evaluative purposes regarding POD in the pediatric population, the Receiver Operating Characteristics (ROC) curve was employed. RESULTS: A total of 211 cases were included in this study, of which 61 (28.9%) developed POD. Participants suffering delirium had lower preoperative rSO2mean, lower preoperative rSO2min, and lower postoperative rSO2min, higher ∆rSO2mean, higher amount of ∆rSO2mean, lower ∆rSO2min (P < 0.05). Preoperative rSO2mean (AUC = 0.716, 95%CI 0.642-0.790), ∆rSO2mean (AUC = 0.694, 95%CI 0.614-0.774), amount of ∆rSO2mean (AUC = 0.649, 95%CI 0.564-0.734), preoperative rSO2min (AUC = 0.702, 96%CI 0.628-0.777), postoperative rSO2min (AUC = 0.717, 95%CI 0.647-0.787), and ∆rSO2min (AUC = 0.714, 95%CI 0.638-0.790) performed well in sensitivity and specificity, and the best threshold were 62.05%, 1.27%, 2.41%, 55.68%, 57.36%, 1.29%. CONCLUSIONS: There is a close relationship between pediatric POD and rSO2. rSO2 could be used as an effective predictor of pediatric POD. It might be helpful to measure rSO2 with NIRS for early recognizing POD and making it possible for early intervention.

A nomogram for predicting postoperative delirium in pediatric patients following cardiopulmonary bypass: A prospective observational study.

OBJECTIVES: To create a nomogram for early delirium detection in pediatric patients following cardiopulmonary bypass. RESEARCH METHODOLOGY/DESIGN: This prospective, observational study was conducted in the Cardiac Intensive Care Unit at a Children's Hospital, enrolling 501 pediatric patients from February 2022 to January 2023. Perioperative data were systematically collected through the hospital information system. Postoperative delirium was assessed using the Cornell Assessment of Pediatric Delirium (CAPD). For model development, Least Absolute Shrinkage and Selection Operator (LASSO) regression was employed to identify the most relevant predictors. These selected predictors were then incorporated into a multivariable logistic regression model to construct the predictive nomogram. The performance of the model was evaluated by Harrell's concordance index, receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis. External validity of the model was confirmed through the C-index and calibration plots. RESULTS: Five independent predictors were identified: age, SpO2 levels, lymphocyte count, diuretic use, and midazolam administration, integrated into a predictive nomogram. This nomogram demonstrated strong predictive capacity (AUC 0.816, concordance index 0.815) with good model fit (Hosmer-Lemeshow test p = 0.826) and high accuracy. Decision curve analysis showed a significant net benefit, and external validation confirmed the nomogram's reliability. CONCLUSIONS: The study successfully developed a precise and effective nomogram for identifying pediatric patients at high risk of post-cardiopulmonary bypass delirium, incorporating age, SpO2 levels, lymphocyte counts, diuretic use, and midazolam medication. IMPLICATIONS FOR CLINICAL PRACTICE: This nomogram aids early delirium detection and prevention in critically ill children, improving clinical decisions and treatment optimization. It enables precise monitoring and tailored medication strategies, significantly contributes to reducing the incidence of delirium, thereby enhancing the overall quality of patient care.

Coping strategies and interventions to alleviate moral distress among pediatric ICU nurses: A scoping review.

BACKGROUNDS: Moral distress significantly affects pediatric ICU nurses, leading to nurse burnout, increased turnover and reducing patient care quality. Despite its importance, there's a notable gap in knowledge on how to manage it effectively. AIMS: This review aimed to systematically identify and analyze coping strategies and interventions targeting moral distress among pediatric nurses in ICU, uncovering research gap and future studies directions. METHODS: A scoping review was conducted followed framework by Levac, Colquhoun, and O'Brien and Arksey and O'Malley. Searches were performed in 11 electrical databases, like PubMed and China Biology Medicine disc, within a timeframe of the database construction to November 2023, and performed literature screening and data extraction. RESULTS: Sixteen articles were ultimately included. Coping strategies adopted by pediatric ICUs nurses can be categorized into adaptive and maladaptive strategies, with the latter including passive acceptance, taking leave, and drinking, while the former involve pursuing interests outside of work, reflection and philosophizing, and communication. Nine articles described and evaluated the effectiveness of interventions for moral distress, categorizing them into individual and institutional levels. Individual-level interventions include Interprofessional Perspective-Taking, the PICU Resiliency Bundle, Ethics Education/Skills, and the Center for Caring. Institutional-level interventions encompasses Comprehensive Care Round, Goals of Care Conversations, Pediatric Ethics and Communication Excellence Rounds, Nursing Ethics Council, and Medical Ethical Decision-Making, though not all were effective in alleviating moral distress. CONCLUSIONS: Nurses often use self-adjustment strategies for moral distress, institutional ethical support focusing on enhancing nurses' moral resilience, promoting reflective thinking and improving communication remains crucial. Various interventions for moral distress are currently available, but nurse engagement is low and their effectiveness remained to be verified. Future studies should explore what aids or hinders these interventions. There's also a need for large, multicenter trials and ongoing evaluations to create effective support systems for pediatric ICU nurses.

Antibiotics influence the risk of anti-drug antibody formation during anti-TNF therapy in Chinese inflammatory bowel disease patients.

Aims: The formation of anti-drug antibodies (ADAs) during anti-tumor necrosis factor (anti-TNF) therapy is reported to lead to reducing serum drug levels, which may bring about a loss of response to treatment. Previous research has suggested an association between specific antibiotic classes and ADA formation during anti-TNF therapy. However, there are few studies specifically examining this association in Chinese inflammatory bowel disease (IBD) patients. Therefore, our study aimed to evaluate the possible effect of antibiotic use on ADA formation to anti-TNF therapy in Chinese patients with IBD. Methods: A total of 166 patients with IBD, including 149 with Crohn's disease (CD) and 17 with ulcerative colitis (UC), were included in this retrospective analysis. These patients were initially treated with anti-TNF therapy (infliximab or adalimumab) after January 2018 and reviewed with available ADA levels before October 2023. After univariable analysis of all the variables, a multivariate Cox proportional hazards model was used to assess the association between antibiotic use and ADA development. Results: Among 166 IBD patients treated with infliximab (108/166, 65.1%) or adalimumab (58/166, 34.9%), 31 patients (18.7%) were measured as positive ADA levels. Cox proportional hazard model demonstrated an increased risk of ADA formation in IBD patients who used ß-lactam-ß-lactamase inhibitor combinations (BL-BLIs) (HR = 5.143, 95%CI 1.136-23.270, p = 0.033), or nitroimidazoles (HR = 4.635, 95%CI 1.641-13.089, p = 0.004) during 12 months before the ADA test. On the contrary, a reduced risk was noted in patients treated with fluoroquinolones (HR = 0.258, 95% CI 0.072-0.924, p = 0.037). Moreover, the median serum infliximab or adalimumab concentration in patients with positive ADA levels was significantly lower than that in patients with negative ADA levels (infliximab: 0.30 vs. 1.85 µg/mL, p < 0.0001; adalimumab: 0.45 vs. 7.55 µg/mL, p = 0.0121). Conclusion: ADA development is associated with various antibiotic classes. BL-BLIs and nitroimidazoles might increase the risk of ADA formation during anti-TNF therapy in Chinese IBD patients, while the treatment with fluoroquinolones could probably reduce such risk. There were certain limitations in the retrospective analysis of the study, therefore, the results are just for reference, and other studies are needed to further confirm our findings.

Platelet-to-Lymphocyte Ratio (PLR), Neutrophil-to-Lymphocyte Ratio (NLR), Monocyte-to-Lymphocyte Ratio (MLR), and Eosinophil-to-Lymphocyte Ratio (ELR) as Biomarkers in Patients with Acute Exacerbation of Chronic Obstructive Pulmonary Disease (AECOPD).

Purpose: The study comprehensively evaluated the prognostic roles of the platelet-to-lymphocyte ratio (PLR), neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), basophil-to-lymphocyte ratio (BLR), and eosinophil-to-lymphocyte ratio (ELR) in patients with acute exacerbation of chronic obstructive pulmonary disease (AECOPD). Patients and Methods: Six hundred and nineteen patients with AECOPD and 300 healthy volunteers were retrospectively included into the study. The clinical characteristics of the patients with AECOPD and the complete blood counts (CBCs) of the healthy volunteers were collected. The associations of PLR, NLR, MLR, BLR, and ELR with airflow limitation, hospital length of stay (LOS), C-reactive protein (CRP), and in-hospital mortality in patients with AECOPD were analyzed. Results: Compared with the healthy volunteers, PLR, NLR, MLR, BLR, and ELR were all elevated in COPD patients under stable condition. PLR, NLR, MLR, and BLR were further elevated while ELR was lowered during exacerbation. In the patients with AECOPD, PLR, NLR, and MLR were positively correlated with hospital LOS as well as CRP. In contrast, ELR was negatively correlated with hospital LOS as well as CRP. Elevated PLR, NLR, and MLR were all associated with more severe airflow limitation in AECOPD. Elevated PLR, NLR, and MLR were all associated with increased in-hospital mortality while elevated ELR was associated with decreased in-hospital mortality. Binary logistic regression analysis showed that smoking history, FEV1% predicted, pneumonia, pulmonary heart disease (PHD), uric acid (UA), albumin, and MLR were significant independent predictors ofin-hospital mortality. These predictors along with ELR were used to construct a nomogram for predicting in-hospital mortality in AECOPD. The nomogram had a C-index of 0.850 (95% CI: 0.799-0.901), and the calibration curve, decision curve analysis (DCA), and clinical impact curve (CIC) further demonstrated its good predictive value and clinical applicability. Conclusion: In summary, PLR, NLR, MLR, and ELR served as useful biomarkers in patients with AECOPD.

Food addiction and its impact on weight status in children and adolescents: The mediating role of responsive eating pattern.

AIMS: This research explores the relationships between food addiction (FA), eating behaviours, and weight status in school-aged children and adolescents, aiming to understand how FA influences weight. METHODS: By using a cross-sectional design, 426 healthy children and their parents were enroled in Eastern China. FA was assessed using the Chinese version of the Dimensional Yale Food Addiction Scale for Children 2.0 (dYFAS-C 2.0), while eating patterns were identified using latent profile analysis (LPA) derived from the Children's Eating Behaviour Questionnaire (CEBQ). Weight status was indicated by Body Mass Index Z Score (BMIZ) and waist-to-height ratio (WHtR). The associations among FA, eating patterns, and weight status were explored using structural equation modelling (SEM). RESULTS: Two eating patterns, the Responsive and the Controlled Eating Patterns, were identified. The Responsive Eating Pattern was characterized by high food responsiveness, enjoyment of food, emotional eating, fast eating, low satiety responsiveness, and food fussiness and was associated with FA and weight status (p < 0.001). The SEM results showed the Responsive Eating Pattern partially mediated the relationship between FA and weight status, with a mediation effect of 1.183 (95% CI [0.784, 1.629]) for BMIZ and 0.043 (95% CI [0.025, 0.063]) for WHtR. CONCLUSION: Increased FA is associated with a higher weight status through a specific eating behaviour pattern characterized by high responsiveness to food, emotional and rapid eating habits, and low satiety. The findings suggest that targeted interventions should take these eating behaviour patterns into account to reduce the impact of FA on weight status among children and adolescents.

A peanut and weed detection model used in fields based on BEM-YOLOv7-tiny.

Due to the different weed characteristics in peanut fields at different weeding periods, there is an urgent need to study a general model of peanut and weed detection and identification applicable to different weeding periods in order to adapt to the development of mechanical intelligent weeding in fields. To this end, we propose a BEM-YOLOv7-tiny target detection model for peanuts and weeds identification and localization at different weeding periods to achieve mechanical intelligent weeding in peanut fields at different weeding periods. The ECA and MHSA modules were used to enhance the extraction of target features and the focus on predicted targets, respectively, the BiFPN module was used to enhance the feature transfer between network layers, and the SIoU loss function was used to increase the convergence speed and efficiency of model training and to improve the detection performance of the model in the field. The experimental results showed that the precision, recall, mAP and F1 values of the BEM-YOLOv7-tiny model were improved by 1.6%, 4.9%, 4.4% and 3.2% for weed targets and 1.0%, 2.4%, 2.2% and 1.7% for all targets compared with the original YOLOv7-tiny. The experimental results of positioning error show that the peanut positioning offset error detected by BEM-YOLOv7-tiny is less than 16 pixels, and the detection speed is 33.8 f/s, which meets the requirements of real-time seedling grass detection and positioning in the field. It provides preliminary technical support for intelligent mechanical weeding in peanut fields at different stages.

Advances in pulmonary rehabilitation for children with bronchial asthma. / æ”¯æ°”ç®¡å“®å–˜æ‚£å„¿è‚ºåº·å¤ä¸´åºŠç ”ç©¶è¿›å±•.

Bronchial asthma is a heterogeneous disease characterized by chronic airway inflammation and airway hyperresponsiveness. With the development of the whole-life-cycle health concept, the focus of treatment for bronchial asthma in children has gradually shifted from pharmacological control to an integrated management model of functional rehabilitation and pharmacological assistance. As a non-pharmacological integrated approach, pulmonary rehabilitation plays an equally important role in the management of childhood asthma as pharmacological treatments. Breathing techniques such as Buteyko breathing, pursed lip breathing, diaphragmatic breathing training, threshold-pressure inspiratory muscle training and yoga breathing can improve lung function indicators such as forced expiratory volume in first second (FEV1), forced vital capacity (FVC), peak expiratory flow (PEF) and maximal voluntary ventilation (MVV) in children. Comprehensive pre-exercise assessment, development of exercise prescriptions, and implementation and evaluation of exercise effects can improve physical fitness, neuromuscular coordination, and self-confidence of children with asthma. The comprehensive interventions of health education, psychological support and nutritional intervention can improve the compliance and effectiveness of rehabilitation training. This article reviews the research progress on respiratory training, physical exercise, and comprehensive interventions in the pulmonary rehabilitation of asthmatic children, to provide theoretical basis and practical guidance for the scientific and rational management of pulmonary rehabilitation of asthmatic children in clinical settings.

Association of dietary patterns with depressive symptoms in Chinese adolescents: a cross-sectional study.

Objective: Depression is highly prevalent in adolescents and may have adverse social and health consequences. To investigate the effect of diet on the occurrence of depression in adolescents, this study examined the correlation between dietary patterns and depression in adolescents. Methods: A total of 853 participants were recruited in September to October 2022 in Taizhou, Zhejiang, China. The Chinese version of the Patient Health Questionnaire-9 was used to assess the subjects' depressive symptoms in the past 2 weeks. Relevant dietary information was obtained through a food frequency questionnaire. The associations between dietary patterns and the risk of depression were assessed using a logistic regression model. Results: Four dietary patterns were identified by factor analysis, including the modern pattern, the snack-aquatic pattern, the traditional pattern, and the vegetarian pattern. The risk of mild depression among adolescents was higher in the Q2 and Q3 groups of the modern model than in the Q1 group of this type, and the risk of mild depression was higher in the Q4 group of the snack-aquatic model than in the Q1 group of this type; while the risk of moderate depressive symptoms was lower in the Q3 group of the vegetarian model compared with the Q1 group. Conclusion: Modern and snack-aquatic patterns are associated with an increased risk of depression in Chinese adolescents, and vegetarian patterns are associated with a reduced risk of depression. The current findings emphasize the importance of adolescents consuming moderate amounts of rice flour, adequate vegetables and fruits, and reducing snack intake.

Intestinal fungi and antifungal secretory immunoglobulin A in Crohn's disease.

The human gastrointestinal tract harbors trillions of commensal microorganisms. Emerging evidence points to a possible link between intestinal fungal dysbiosis and antifungal mucosal immunity in inflammatory bowel disease, especially in Crohn's disease (CD). As a protective factor for the gut mucosa, secretory immunoglobulin A (SIgA) prevents bacteria from invading the intestinal epithelium and maintains a healthy microbiota community. In recent years, the roles of antifungal SIgA antibodies in mucosal immunity, including the regulation of intestinal immunity binding to hyphae-associated virulence factors, are becoming increasingly recognized. Here we review the current knowledge on intestinal fungal dysbiosis and antifungal mucosal immunity in healthy individuals and in patients with CD, discuss the factors governing antifungal SIgA responses in the intestinal mucosa in the latter group, and highlight potential antifungal vaccines targeting SIgA to prevent CD.

Deep multi-modal fusion network with gated unit for breast cancer survival prediction.

Accurate survival prediction is a critical goal in the prognosis of breast cancer patients because it can help physicians make more patient-friendly decisions and further guide appropriate treatment. Breast cancer is often caused by genetic abnormalities, which prompts researchers to consider information such as gene expression and copy number variation in addition to clinical data in their studies. The integration of these multi-modal data can improve the predictive power of models. However, with the highly unbalanced information of breast cancer patient data, it becomes a new challenge for breast cancer patient survival prediction to fully extract the characteristic information of these multi-modal data and to consider the complementarity of this information. To this end, we propose a deep multi-modal fusion network (DMMFN) to predict the five-year survival of breast cancer patients by integrating clinical data, copy number variation data, and gene expression data. The imbalanced dataset is first processed using the oversampling method SMOTE-NC. Then the abstract modal features of the multi-modal data are extracted by the two-layer one-dimensional convolutional neural network and the bi-directional long short-term memory network. Next, the weight coefficients of each modal data are dynamically adjusted using gated multimodal units to obtain fusion features. Finally, the fusion features are fed into the MaxoutMLP classifier to obtain the final prediction results. We conducted experiments on the METABRIC dataset to verify the validity of the multi-modal data and compared it with other methods. The comprehensive performance evaluation shows that DMMFN has better prediction performance.

Existential experiences and perceptions of death among children with terminal cancer: An interpretative qualitative study.

BACKGROUND: Exploring the experience and understanding of death in children with terminal cancer is important to provide them with appropriate care. However, most studies have focused on the perspectives of parents and healthcare professionals, and few have focused on the end-of-life experiences of children. AIM: To advance the understanding of end-of-life experiences and perceptions of death in children with cancer. DESIGN: Interpretative qualitative study using semi-structured interviews. Data were analyzed using reflexive thematic analysis. SETTING/PARTICIPANTS: The study was conducted at the department of oncological surgery, Children's Hospital, Zhejiang University School of Medicine. Ten children aged 8-17 with terminal cancer were included in the study. RESULTS: Four major themes (and eight sub-themes) were identified from the findings: (1) helplessness in the face of death (loneliness, loss of control); (2) desire to connect with the world they left (reluctantly to be forgotten, sense of self-worth); (3) perceptions and attitudes toward death (separating from loved ones, embracing death); (4) expectations of future life (promoting comfort, fulfilling wishes). CONCLUSIONS: Children with terminal cancer have a strong sense of loneliness and a desire to connect with the world they have left behind. Differences in children's perceptions and attitudes about death suggest that healthcare professionals should focus on their experiences and needs and provide personalized palliative care services to children and their families to improve their quality of life.

Risk Factors of Perioperative Brain Injury in Children Under Two Years Undergoing Coarctation Repair.

BACKGROUND: To investigate clinical manifestations and factors of perioperative brain injury (PBI) after surgical repair of coarctation of the aorta (CoA) combined with other heart malformations under cardiopulmonary bypass (CPB) in children under two years. METHODS: The clinical data of 100 children undergoing CoA repair were retrospectively reviewed between January 2010 and September 2021. Univariate and multivariate analyses were performed to identify factors of PBI development. Hierarchical and K-means cluster analyses were conducted to evaluate the association between hemodynamic instability and PBI. RESULTS: Eight children developed postoperative complications, and all of them had a favorable neurological outcome one year after surgery. Univariate analysis revealed eight risk factors associated with PBI. Multivariate analysis indicated operation duration (P = 0.04, odds ratio [OR], 2.93; 95% confidence interval [CI], 1.04 to 8.28) and pulse pressure (PP) minimum (P = 0.01; OR, 0.22; 95% CI, 0.06 to 0.76) were independently associated with PBI. The following three parameters emerged for cluster analysis: PP minimum, mean arterial pressure (MAP) dispersion, and systemic vascular resistance (SVR) average. Using cluster analysis, PBI mainly occurred in subgroups 1 (12%, three of 26) and 2 (10%, five of 48). The mean value of PP and MAP in subgroup 1 was significantly higher than in subgroup 2. The mean SVR in subgroup 1 was the highest. The lowest PP minimum, MAP, and SVR were observed in subgroup 2. CONCLUSION: Lower PP minimum and longer operation duration were independent risk factors for developing PBI in children under two years during CoA repair. Unstable hemodynamics should be avoided during CPB.

Intervention strategies for white noise alleviating procedural pain in newborns: A systematic review.

AIMS AND OBJECTIVE: To systematically evaluate the current intervention strategies of white noise alleviating procedural pain in newborns. METHODS: This review was conducted following the PRISMA guideline. Seventeen databases National Guideline Clearinghouse, up to date, Clinical Evidence, BMJ best practice, Cochrane library, OVID, PubMed, Medline, EMBASE, Web of Science, CHINHAL, Medlive, China Biology Medicine disc, Chinese Clinical Trial Registry, China National Knowledge Infrastructure, China Science and Technology Journal Database, Wanfang Data Knowledge Service Platform were employed, and the studies about pain-relieving with white noise in newborns published before June 2022 was included. Quality of studies was evaluated by using the Cochrane Handbook for Systematic Reviews of Interventions. RESULTS: 18 studies were included, with sample sizes ranging from 32-296 cases. Intervention indices included duration, distance, volume, music type and outcome measure. Duration varies from study to study, from 5 min before to 5 min after the procedures. The distance was controlled at 10-60 cm, volume was controlled at 45-60 dB and music type was selected from Orhan Osman's album "Kolic" in most studies. Outcome measures included physiological indicators, neurophysiological indicators, behavioural indicators and pain score. Differences in duration leading to different white noise effects was found, but no studies have shown whether there is an effect of different volume, distance or music type. CONCLUSIONS: Based on this review, we recommend the following intervention strategies: the duration is set from 1 min before to 3 min after the procedures, the distance is decided according to the actual clinical situation, the volume is controlled at 45-55 dB (55 dB is optimal), the music type is selected to simulate intrauterine sounds, and outcome measures can choose physiological indicators, neurophysiological indictors, behavioural indicators and pain score depending on specific department and population. It is important to further explore the best intervention strategies. RELEVANCE TO CLINICAL PRACTICE: In addition to providing a set of intervention strategies, this review could be used as evidence for relieving procedural pain in newborns. PATIENT OR PUBLIC CONTRIBUTION: No Patient or Public Contribution. Data were obtained from others' literature.

Parental involvement in postoperative pain management among children in a urology ward: A best practice implementation project.

AIM: Postoperative pain has adverse effects on children with urological problems, including sleep disturbances, incision dehiscence, bleeding and delayed recovery. Accurate parental assessment of children's behaviours and responses could help to manage postoperative pain. We aimed to implement evidence-based practice for parental involvement in a urology ward, to increase parents' participation in children's postoperative pain management. DESIGN: The project was conducted in a paediatric urology ward using the framework and methods of the Fudan University Evidence-Based Nursing Center's Evidence-based Continuous Quality Improvement Model. METHODS: Fifteen audit criteria were used to represent best practice recommendations for parental involvement in postoperative pain management. A pre-implementation audit was conducted with 211 randomly sampled children and parents. Obstacles, promoting factors and key strategies were analysed, and evidence-based interventions implemented to improve compliance. A follow-up audit using the same audit criteria was conducted with 202 children and parents to assess the effect of targeted strategies on compliance with best practice. The SQUIRE guidelines were followed. RESULTS: At the baseline audit, compliance with the evidence-based criteria was 0%-71.5%; only five audit criteria achieved a compliance rate > 60%. After best practice implementation, the follow-up audit showed compliance improvements for all criteria; compliance for three criteria improved to 100%. PATIENT OR PUBLIC CONTRIBUTION: This best practice implementation project improved parents' participation in children's postoperative pain management. The findings demonstrate how audits can promote best practice in postoperative pain management for children. Additional studies will be conducted to address children's postoperative life quality based on best practice.

Factors Affecting Family Management Among Chinese Parents of Children With Leukemia: A Multisite Study.

BACKGROUND: Effective family management can improve the ability of children's families to cope with the disease. However, the family management styles of children with leukemia are unknown. OBJECTIVE: This study used a family management style framework and structural equation model to determine the direct and indirect predictors of family management of children with leukemia. METHODS: A total of 496 parents of children with leukemia completed the Family Management Measure, the Feetham Family Functioning Survey, the Social Support Rating Scale, and a demographic family information form. We used structural equation modeling to explore the direct and indirect effects of the study variables on family management styles. RESULTS: Family functioning, family income, parental education level, and geographic location affect family management directly, among which family functioning has the most significant coefficient in the model (0.53). Siblings and social support can affect family management through the mediating effect of family functioning. Employment change can directly affect family management (-0.27) and indirectly affect family functioning (-0.08). CONCLUSIONS: Our results support the family management style framework. Individual and family factors such as family income, parental education level, geographic location, employment change, siblings, and social support contribute to the ease or difficulty of family management. In addition, family functioning can also mediate between contextual influences and family management styles. IMPLICATIONS FOR PRACTICE: Family functioning plays a vital role in relationships between contextual influences and family management. We can construct family management interventions according to family management influencing factors.

Comparative analysis of subgingival microbiota in patients with mild, moderate, and severe chronic periodontitis.

In this study, we explored the suspected pathogens of chronic periodontitis at different stages of occurrence and development. We collected 100 gingival crevicular fluid samples, 27, 27, and 26 from patients with mild, moderate, and severe chronic periodontitis, respectively, and 20 from healthy individuals. Pathogens were detected using a 16S rRNA metagenomic approach. Quantitative Insights in Microbial Ecology, Mothur, and other software were used to analyze the original data, draw relative abundance histograms and heat maps, and calculate flora abundance and diversity indexes. We identified 429 operational taxonomic units, covering 13 phyla, 20 classes, 32 orders, 66 families, and 123 genera from the four groups of samples. Each group showed microbial diversity, and the number of new species of bacterial flora in the gingival crevicular fluid samples gradually increased from the healthy to the severe chronic periodontitis group. There was a significant difference in the relative abundance of the core flora at the phylum, class, order, family, and genus classification levels. Our data indicated a certain correlation between the changes in the subgingival microbial structure and the occurrence and development of chronic periodontitis, which might be able to provide a reference for the diagnosis, treatment and prevention of chronic periodontitis.

Knowledge, attitudes and practices of enhanced recovery after surgery among paediatric surgical nurses in China: A Cross-Sectional study.

AIM: To investigate paediatric surgical nurses' knowledge, attitudes and practices (KAP) regarding enhanced recovery after surgery (ERAS). DESIGN: A cross-sectional study. METHODS: A 34-question survey was developed. An electronic version of the questionnaire was distributed to nurses working in paediatric surgical departments of 22 tertiary hospitals from 14 provinces of China by means of convenience sampling from February to April 2021. A total of 855 nurses' data was used as the final sample. The statistical analysis included nonparametric test, Spearman's correlation and multiple linear regression. RESULTS: There is still room for improvement regarding the KAP of paediatric surgical nurses, especially in the knowledge of "postoperative recovery" and "preoperative preparation". The influencing factors of KAP were educational level, geographical region (South, Central, North, Northwest), years of work experience, hospital category (general hospital, women and children's hospital), and familiarity with ERAS.

Median effective dose of 0.2% ropivacaine for ultrasound-guided median nerve block in young children.

OBJECTIVE: To determine the median effective dose (ED50) and the 95% effective dose (ED95) of 0.2% ropivacaine for ultrasound-guided lower forearm median nerve block in paediatric patients. METHODS: Eligible children were American Society of Anesthesiologists (ASA) status I-II scheduled to have elective open surgery for trigger thumb repair. Patients were stratified into two age groups: 1- to 3-year-olds and 3- to 6-year-olds. The ED50 was determined by Dixon's up-and-down method. The first patient received an ultrasound-guided median nerve block by injection of 2 mL of 0.2% ropivacaine. Each subsequent patient's dose was determined by the response of the previous patient, the doses being adjusted in intervals of 0.2 mL. In addition, the 95% effective dose (ED95) was obtained using a probit regression approach. The patients' general condition, postoperative pain scores, and adverse events were recorded. RESULTS: A total of 52 children who were scheduled to undergo open surgery for trigger thumb were included in this study: 28 in the 1- to 3-year-olds group and 24 in the 3- to 6-year-olds group. The ED50 (95% confidence interval) values were 0.9 (0.44-1.36) mL in 1- to 3-year-olds and 1.4 (1.14-1.66) mL in 3- to 6-year-olds. The ED95 (95% confidence interval) values were 1.5 (0.98-1.58) mL in 1- to 3-year-olds and 1.7 (1.54-1.78) mL in 3- to 6-year-olds. No adverse events occurred. CONCLUSIONS: A single dose of ropivacaine was an effective agent for young children requiring ultrasound-guided lower forearm median nerve block in open surgery for trigger thumb. The ED50 (95% confidence interval) values were 0.9 (0.44-1.36) mL in 1- to 3-year-olds and 1.4 (1.14-1.66) mL in 3- to 6-year-olds. The ED95 (95% confidence interval) values were 1.5 (0.98-1.58) mL in 1- to 3-year-olds and 1.7 (1.54-1.78) mL in 3- to 6-year-olds.
