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.

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.

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.

Long-Term Prognostic Factors in Patients With Antineutrophil Cytoplasmic Antibody-Associated Vasculitis: A 15-Year Multicenter Retrospective Study.

Background: Antineutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a multisystem autoimmune disease with small-vessel involvement. In AAV, microscopic polyangiitis (MPA) and granulomatosis with polyangiitis (GPA) are major clinicopathologic variants. In addition, myeloperoxidase (MPO) and proteinase 3 (PR3) are major target antigens. The objective of the study was to explore the predictive factors for long-term survival in AAV patients. Materials and Methods: A multicenter retrospective study was carried out on 407 patients between 2005 and 2020. Clinical parameters were obtained from laboratory tests including the ANCA types, antinuclear antibody (ANA), extractable nuclear antigen (ENA), anti-streptolysin O (ASO), glomerular filtration rate (GFR), and the laboratory examinations for the blood routine, liver function, renal function, and immunity, etc. The data for clinical parameters were collected from electronic medical records (EMRs), and the data for patient survival were acquired through regular follow-up. The association of clinical parameters with overall survival (OS) along with 3-year and 5-year survival rates was analyzed, and the nomogram as a predictive model was established according to the analysis results. Results: In the present study, 336 (82.6%) patients and 46 (11.3%) patients were diagnosed with MPA and GPA, respectively. The mean and median OS for all the patients were 2,285 and 2,290 days, respectively. The 1-year, 3-year, 5-year, and 10-year cumulative survival rates for all the patients were 84.2%, 76.3%, 57.2%, and 32.4%, respectively. Univariate and multivariate survival analyses indicated that the independent prognostic factors included age, pathological categories (MPA, GPA, and other types), serum ANCA types (negative or positive for MPO and/or PR3), ANA, ASO, GFR, lymphocyte, neutrophil-to-lymphocyte ratio (NLR), and C-reactive protein (CRP), and these clinical parameters except for ASO were used to construct a nomogram. The nomogram for 3-year and 5-year survival rates had a C-index of 0.721 (95% CI 0.676-0.766). The calibration curves showed that the predicted values of the nomogram for 3-year and 5-year survival rates were generally consistent with practical observed values, and decision curve analysis (DCA) further demonstrated the practicability and accuracy of the predictive model. Conclusion: Laboratory tests at diagnosis have great significance in the prediction of long-term survival in AAV patients.

Enhanced recovery after surgery strategy to shorten perioperative fasting in children undergoing non-gastrointestinal surgery: A prospective study.

BACKGROUND: Enhanced recovery after surgery strategies are increasingly implemented to improve the management of surgical patients. AIM: To evaluate the effects of new perioperative fasting protocols in children ≥ 3 mo of age undergoing non-gastrointestinal surgery. METHODS: This prospective pilot study included children ≥ 3 mo of age undergoing non-gastrointestinal surgery at the Children's Hospital (Zhejiang University School of Medicine) from January 2020 to June 2020. The children were divided into either a conventional group or an ERAS group according to whether they had been enrolled before or after the implementation of the new perioperative fasting strategy. The children in the conventional group were fasted using conventional strategies, while those in the ERAS group were given individualized fasting protocols preoperatively (6-h fasting for infant formula/non-human milk/solids, 4-h fasting for breast milk, and clear fluids allowed within 2 h of surgery) and postoperatively (food permitted from 1 h after surgery). Pre-operative and postoperative fasting times, pre-operative blood glucose, the incidence of postoperative thirst and hunger, the incidence of perioperative vomiting and aspiration, and the degree of satisfaction were evaluated. RESULTS: The study included 303 patients (151 in the conventional group and 152 in the ERAS group). Compared with the conventional group, the ERAS group had a shorter pre-operative food fasting time [11.92 (4.00, 19.33) vs 13.00 (6.00, 20.28) h, P < 0.001), shorter preoperative liquid fasting time [3.00 (2.00, 7.50) vs 12.00 (3.00, 20.28) h, P < 0.001], higher preoperative blood glucose level [5.6 (4.2, 8.2) vs 5.1 (4.0, 7.4) mmol/L, P < 0.001], lower incidence of thirst (74.5% vs 15.3%, P < 0.001), shorter time to postoperative feeding [1.17 (0.33, 6.83) vs 6.00 (5.40, 9.20), P < 0.001], and greater satisfaction [7 (0, 10) vs 8 (5, 10), P < 0.001]. No children experienced perioperative aspiration. The incidences of hunger, perioperative vomiting, and fever were not significantly different between the two groups. CONCLUSION: Optimizing fasting and clear fluid drinking before non-gastrointestinal surgery in children ≥ 3 mo of age is possible. It is safe and feasible to start early eating after evaluating the recovery from anesthesia and the swallowing function.

The effectiveness of a parent participation in postoperative pain management programs for children in a urology ward: A randomized controlled trial.

BACKGROUND: Postoperative pain has adverse effects on children after urology treatment, including sleep disturbance, incision dehiscence, bleeding, and delayed recovery. Parents, as the most direct caregivers of children, can make accurate assessments of children´s personal behaviors and responses, which is very important for the management of postoperative pain in children. PURPOSE: The purpose of the current study was to develop a Parent Participation in Postoperative Pain Management Program for children in a urology ward and to evaluate its effects on children's postoperative pain scores and other outcome indicators. DESIGN: This research comprised two phases. The first phase was the development of a Parent Participation in Postoperative Pain Management Program. The second phase was a randomized controlled trial between two groups, and was carried out in a 45-bed inpatient urology ward of a tertiary children's hospital in China. In the trial, 211 children and their parents were randomly selected as a control group between July 1 and August 15, 2019, and 202 children and their parents were randomly selected as an intervention group between August 16 and September 15, 2019. METHODS: Following the framework and methods of the Evidence-based Continuous Quality Improvement Model developed at Fudan University Evidence-Based Nursing Center, we systematically gathered evidence regarding parental involvement in postoperative pain management in children to construct the program. To evaluate the program's effectiveness, the control group performed routine postoperative pain management, while the intervention group underwent the Parent Participation in Postoperative Pain Management Program. The management period was during hospitalization, and generally ranged 3-7 days. The Statistical Table of Pain Assessment for Children after Urology was employed by researchers. FINDINGS: The results revealed no significant differences in demographic characteristics between the two groups of children and their parents. Children's pain scores during dressing removal (Z = -3.108, p = 0.002), at discharge (Z = -2.185, p = 0.029) and during catheter removal (Z = -6.553, p = 0.000) were significantly lower in the intervention group compared with the control group. CONCLUSIONS AND CLINICAL RELEVANCE: The Parent Participation in Postoperative Pain Management Program was found to be effective for alleviating postoperative pain scores among children, and provided useful information regarding postoperative pain management in children involving four aspects of parental involvement: cognition, guidance, documentation and support.

Extravasation of chemotherapeutic drug from an implantable intravenous infusion port in a child: A case report.

BACKGROUND: Drug extravasation is a complication of totally implantable access port (TIAP) use and could cause tissue injury and sustained organ dysfunction. Therefore, the clinical management of children with TIAP is challenging. CASE SUMMARY: This was a case of extravasation of a chemotherapeutic drug (paclitaxel) from an implantable infusion port in a 23-mo old child. After fully evaluating the skin at the site of extravasation, the nurse continued to use the infusion port to complete the follow-up chemotherapeutic course. The skin around the infusion port was red, and showed no ulceration, swelling, or induration at discharge. CONCLUSION: Since children are more active and often noncompliant, it is necessary to appropriately train pediatric nurses caring for individuals with TIAPs, and any abnormal situation should be timely addressed.

Restoration of critical defects in the rabbit mandible using osteoblasts and vascular endothelial cells co-cultured with vascular stent-loaded nano-composite scaffolds.

The success of large bone defect repair with tissue engineering technology depends mainly on angiogenesis and osteogenesis. In this study, we prepared poly-caprolactone/nano-hydroxyapatite/beta-calcium phosphate (PCL/nHA/ß-TCP) composite scaffolds loaded with poly-(lactic-co-glycolic acid)/nano-hydroxyapatite/collagen/heparin sodium (PLGA/nHA/Col/HS) nanofiber small vascular stent by electrospinning and hot press forming-particle leaching methods. Supramolecular electrostatic self-assembly technology was used to modify the surfaces of small vascular stents to aid in hydrophilicity and anticoagulation. The surfaces of composite scaffolds were modified with an Arg-Gly-Asp (RGD) short peptide by physical adsorption to supply cell adhesion sites. The scaffolds were then combined with rabbit bone marrow-derived osteoblasts (OBs) and rabbit bone marrow-derived vascular endothelial cells (RVECs) to construct large, biologically active vascularized tissue-engineered bone in vitro; this bone was then used to repair critical bone defects in rabbit mandibles. Mechanical and biocompatibility testing results showed that PCL/nHA/ß-TCP composite scaffolds loaded with small vascular stents had good surface structure, mechanical properties, biocompatibility, and bone-regeneration induction potential. Twelve weeks after implantation, histological analysis and X-ray scans showed that the use of osteoblasts and vascular endothelial cells co-cultured with PCL/nHA/ß-TCP scaffolds was sufficient to repair critical defects in rabbit mandibles.

[Study on the accuracy of Co-Cr-Mo alloy removable partial denture framework fabricated by selective laser melting].

PURPOSE: To evaluate the accuracy of Co-Cr-Mo alloy removable partial denture (RPD) frameworks, which were fabricated by selective laser melting(SLM) technology. METHODS: 3Shape 3D optical scanner was used to scan a plaster model of maxillary Kennedy I dentition defect, and the obtained 3D topographical data were reconstructed into a digital model. Computer-aided design (CAD) of RPD framework was performed using 3shape design software. Five Co-Cr-Mo RPD frameworks were fabricated by SLM technology, then each framework was scanned to obtain 3D data and compared with the original CAD data, respectively, to evaluate the match accuracy. RESULTS: The Co-Cr-Mo scaffolds were in good position on the plaster model, and the tissue surface was adhered to the plaster model without warping. The overall 3D deviation from the original model was (0.088±0.021) mm. CONCLUSIONS: The Co-Cr-Mo framework fabricated by SLM technology in this experiment has less deviation and higher accuracy.

[Evaluation of dental medical quality based on efficacy coefficient model].

PURPOSE: To evaluate the dental quality comprehensively by data model of efficacy coefficient based on the principle of multi-objective programming. METHODS: The correlation index of dental medical quality was selected by Delphi method, while the index weight was determined by the scale of the analytic hierarchy process. Then efficacy coefficient method was used to evaluate the dental quality of Shanghai Stomatological Hospital in a certain period. RESULTS: During the period of 2016-2017, the D value of the efficiency coefficient was 84.92, 83.41, 86.99 and 81.98, respectively, which demonstrated that the overall quality of the hospital was in good condition. CONCLUSIONS: The efficiency coefficient method can objectively reflect the comprehensive level of medical quality, which can provide a strong support for comprehensive evaluation and control of the quality of dental hospital.

Clinical Assessment of Histidine-Tryptophan-Ketoglutarate Solution and Modified St. Thomas' Solution in Pediatric Cardiac Surgery of Tetralogy of Fallot.

The objective of this study is to compare the myocardium protective effect of Bretschneider's histidine-tryptophan-ketoglutarate (HTK) solution versus Modified St. Thomas' (STH) solution in pediatric cardiac surgery of Tetralogy of Fallot (TOF). Seventy-seven pediatric patients of TOF who received the total surgical repair were reviewed, from January 2014 to October 2015. A horizontal comparison between HTK solution and modified STH solution has been made since the HTK solutions were started to be used in our hospital. The patients were divided into the HTK group (n = 35) and the STH group (n = 33). The perioperative values of the groups were assessed in this study. The primary endpoints including spontaneous cardiac re-beating time, intensive care unit (ICU) stay, overall stay, mechanical ventilation postoperation, postoperation stay, overall stay, and perioperative echocardiographic results were analyzed in this study. We found that spontaneous cardiac re-beating time of the HTK group was significantly shorter than that of the STH group (0.26 min ± 0.56 vs. 1.33 ± 1.02, P < 0.001). There were no significant differences between the two groups in ICU stay (P = 0.29), postoperative mechanical ventilation time (P = 0.84), overall stay (0.73); and the mortalities of the two groups were similar (2.9 vs. 3.0%). Aimed at pediatric cardiac surgery of TOF, this study suggests that with similar aorta cross-clamping time, modified STH solution is as safe as HTK solution.

Paragonimiasis in chinese children: 58 cases analysis.

OBJECTIVE: To analyze the clinical and radiological features of paragonimiasis in children and raise the awareness of this disease. METHODS: A total of 58 paragonimiasis patients were reviewed. They were 42 boys and 16 girls aged 2.0 to 15.3 years. FINDINGS: Among these patients, 20 were diagnosed in the recent 5 years, 46 with a history of raw water or food ingestion. Except 2 patients without any complaint, the most common features involved the systemic (41, 70.7%) and respiratory systems (43, 74.1%), followed by abdominal, cardiac and nervous systems, with rash and mass. Eosinophilia was noted in 46 (79.3%) patients, granulocytosis in 45 (77.6%), anemia in 14 (24.1%), and thrombocytopenia in 3. Imageology showed pneumonia in 26 (44.8%) patients, pleurisy in 28 (48.3%), hydropericardium in 17 (29.3%), ascites in 16 (27.6%), and celiac lymphadenitis in 13 (22.4%). Besides hepatomegaly and splenomegaly, calcification and multiple lamellar low echogenic areas in the liver were noted, each in one patient. Abnormal brain imaging was noted in 4 of 10 patients. Karyocyte hyperplasia with eosinophilia was noted in all the 19 patients who received bone marrow puncture. CONCLUSION: Paragonimiasis should be considered in the differential diagnosis of patients with multiple organs or system lesions, especially those with eosinophilia, serous cavity effusion, respiratory, cardiac, digestive system, nervous system abnormality, and/or mass. Healthy eating habit is helpful for paragonimiasis prevention.
