In Japan, children with specific underlying conditions are eligible to receive palivizumab to prevent severe RSV disease. However, the association between palivizumab eligibility and RSV infection severity remains unclear. This study examined RSV infection severity and hospitalization outcomes in Japanese infants and children according to palivizumab eligibility and identified their associated factors.METHODSUsing insurance claims data from 12 municipalities, we identified RSV cases aged ≤24 months between April 2017 and March 2022. The patients' characteristics and hospitalization status were analyzed according to the presence of palivizumab-indicated underlying conditions. Regression models were used to identify factors associated with hospitalization, length of stay (LOS), and hospital expenditures.RESULTSWe analyzed 1025 first-time RSV cases (860 infants <12 months and 165 children 12-24 months old). There were 777 (90.3%) palivizumab-ineligible infants and 83 (9.7%) palivizumab-eligible infants. Only 13 (15.7%) palivizumab-eligible infants had received palivizumab in the month before RSV infection, and 8 required hospitalization. RSV hospitalization was significantly associated with age (odds ratio: 0.84, 95% confidence interval: 0.79-0.88), palivizumab-indicated underlying conditions (1.82, 1.13-2.89), and non-indicated high-risk conditions (4.87, 2.28-10.99). These factors were also associated with LOS. Hospital expenditures were associated with age, high-risk conditions and LOS.CONCLUSIONSPalivizumab-indicated underlying conditions, high-risk conditions, and younger age are risk factors for RSV hospitalization. Most hospitalized patients did not receive palivizumab in the month before RSV infection despite being eligible, suggesting that some hospitalizations were preventable through appropriate palivizumab use.","PeriodicalId":501652,"journal":{"name":"The Pediatric Infectious Disease Journal","volume":"53 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-11","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193796","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The optimal maximum diameter cutoff of the ileocecal lymph nodes was also explored to optimize differentiation between these 2 diseases.METHODSWe included pediatric patients <15 years old who met the diagnostic criteria for Kawasaki disease. Stool culture testing, loop-mediated isothermal amplification of stool specimens, and serological diagnosis were performed to confirm the presence or absence of Y. pseudotuberculosis infection.RESULTSOf the 122 patients included in the analysis, 17 were confirmed to have Y. pseudotuberculosis infection and 105 were not. The age (in months), white blood cell count, C-reactive protein level, prediction score (risk score) for nonresponse to intravenous immunoglobulin, and number of intravenous immunoglobulin doses did not differ significantly between the Y. pseudotuberculosis-positive and -negative groups. The maximum diameter of ileocecal lymph nodes was 6.0 (5.5-9.5) mm in the Y. pseudotuberculosis-positive group and 3.0 (2.5-3.8) mm in the Y. pseudotuberculosis-negative group (numbers presented as median, interquartile range), with a significantly larger diameter in the Y. pseudotuberculosis-positive group (P < 0.01, Mann-Whitney U test), suggesting potency of ultrasonography.CONCLUSIONIn patients meeting the diagnostic criteria for Kawasaki disease, the possibility of Y. pseudotuberculosis infection is significantly higher if the maximum ileocecal lymph node diameter ≥5.1 mm.

This study aimed to construct a predictive nomogram of the risk of HAIs in burned children.METHODSChildren admitted to the burn unit of Wuhan Third Hospital between 2020 and 2022 were included. The univariate and multivariate logistic regression analyses were adopted to ascertain predictors of HAIs. A nomogram was developed to predict the HAI risk of each patient, with receiver operating characteristic curves and calibration curves being generated to assess its predictive ability. Furthermore, decision and impact curves were used to assess the clinical utility.RESULTSOf 1122 burned children, 61 (5.5%) patients experienced HAIs. The multivariate analysis indicated that total burn surface area, length of stay, surgery, central venous catheter use and urinary catheter use were the independent risk factors of HAIs. Using these variables, we developed a predictive nomogram of the occurrence of HAIs in burned children, and the internal validation results demonstrated good discrimination and calibration of the nomogram. The area under the curve values of the nomogram was 0.926 (95% CI, 0.896-0.957). The calibration curve showed high consistency between the actual and predicted HAIs. The decision and impact curve indicated that the nomogram was of good clinical utility and more credible net clinical benefits in predicting HAIs.CONCLUSIONSThe present study constructed a nomogram for predicting the risk of HAIs in burned children. This nomogram may strengthen the effective screening of patients at high risk of HAIs.","PeriodicalId":501652,"journal":{"name":"The Pediatric Infectious Disease Journal","volume":"25 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-09-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142193751","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

This study objectively defines an outcome of complicated osteomyelitis and explores an illness severity-based model with an improved ability to predict this outcome as soon and accurately as possible, comparing it to existing models.METHODSChildren with Staphylococcus aureus acute hematogenous osteomyelitis (n = 438) were retrospectively studied to identify adverse events and predictors of severity. The outcome of complicated osteomyelitis was ultimately defined as the occurrence of any major or at least 3 minor adverse events, which occurred in 52 children.

The bacterial etiologies were confirmed using matrix-assisted laser desorption ionization-time of flight mass spectrometry. The antibiotic resistance patterns were determined using the automated disc diffusion method (Bio-Rad) and the results were interpreted based on the European Committee on Antimicrobial Susceptibility Testing 2021 breakpoints. Extended-spectrum β-lactamases were detected using a double disc synergy test and confirmed by Mast discs (Mast Diagnostica GmbH).\u0000\u0000\u0000RESULTS\u0000A total of 152 pathogens were identified. Of these, Staphylococcus aureus (18.4%) was the predominant isolate followed by Klebsiella pneumoniae (15.1%) and Escherichia coli (10.5%). All the isolates exhibited a high rate of resistance to first- and second-line antibiotics ranging from 73.3% for gentamicin to 93.3% for ampicillin. Furthermore, 74.4% of the Gram-negative isolates were extended-spectrum β-lactamase producers and 57.1% of S. aureus strains were methicillin resistant.
