Views of Mental Health Nurses on Responding to Clinical Aggression on General Wards.

The overall aim of this study was to explore the views of mental health nurses (MHNs) about their experience of responding to workplace violence (WPV) and aggression (code greys and blacks) within acute general wards. WPV continues to pose a significant source of challenge within healthcare settings despite several initiatives that have been trialled over the years. It has the potential to impact patient care and overall staff health and well-being. Nurses play a significant role in the management of WPV; hence, it is important to understand how they respond to and manage incidents of WPV. The study design was an explorative descriptive qualitative design. Data were collected through semi-structured interviews involving n = 10 MHNs working within a mental health consultation liaison team that responds to incidents of violence and aggression (codes grey and black) in acute general wards. Participants were recruited using a convenient sampling method. Data were analysed using thematic analysis. The findings of this study highlighted the following themes: (1) Patient care (subthemes: patient frustration with hospital processes, lack of time and resources); (2) Staffing skills and confidence (subthemes: lack of adequate training, inability to intervene early and communication skills); (3) Understanding patient behaviours (subthemes: it's a psychiatry problem and zero tolerance approach). The management of WPV within acute hospital settings needs to be given due attention by healthcare services. Although a number of organisations are developing measures and guidelines to manage WPV, there is still a gap in the ability of general nursing staff to properly manage such incidences. Proper attention needs to be taken to the training of staff.

Realist synthesis of a rapid response system in managing mental state deterioration in acute hospital settings.

Mental state deterioration in patients poses significant challenges in healthcare, potentially resulting in adverse outcomes for patients and continued reliance on restrictive interventions. Implementing evidence-based approaches such as a rapid response system that prioritises early identification and intervention can effectively manage adverse outcomes. However, little is known regarding the effectiveness of these interventions. The objective of this synthesis was to test and refine initial programme theories by synthesising evidence to understand what works, for whom and under what circumstances. Based on the realist synthesis methodology, we searched EMBASE, CINAHL, MEDLINE, the Cochrane Library and grey literature for evidence to inform contexts, mechanisms and outcomes on the functioning of a rapid response model. We identified 28 relevant sources encompassing peer-reviewed journal articles and grey literature. This synthesis identified three important elements that contribute to the effectiveness of a rapid response system for managing mental state deterioration: care processes, therapeutic practices and organisational support. Essential elements include improving confidence and clinical skills through training, timely assessment and intervention, teamwork, communication and the creation of governance structures for monitoring and evaluation. To ensure the effectiveness, an organisation must adopt a comprehensive approach that incorporates organisational support, resource allocation, training, clear communication channels and commitment to continuous quality improvement. However, implementing interventions within a complex healthcare system requires thoughtful consideration of the organisational culture and governance structures. By taking a comprehensive and holistic approach to improvement initiatives, organisations can strive to achieve optimal outcomes in managing mental state deterioration and improving patient care.

Realist synthesis protocol on the effectiveness of a rapid response system in managing mental state deterioration in acute hospital settings.

INTRODUCTION: Patient mental state deterioration impacts patient outcomes, staff and increases costs for healthcare organisations. Mental state is broadly defined to include not only mental health but a broad range of cognitive, emotional and psychological well-being factors. Mental state deterioration is inconsistently identified and managed within acute and tertiary medical settings. This protocol aims to synthesise the evidence to test and refine initial programme theories that outline the functioning of a rapid response system. METHODS AND ANALYSIS: This synthesis will be guided by Pawson's key steps in realist reviews. We will clarify the scope of synthesis through an initial literature search, focusing on understanding the functioning of rapid response system in managing patients presenting with mental state deterioration in acute hospital settings. Initial programme theories will be refined by developing a search strategy to comprehensively search electronic databases for relevant English language peer-reviewed studies. Additionally, we will search the grey literature for sources to supplement theory testing. An abstraction form will be developed to record the characteristics of literature sources. We will use spreadsheets to code and report contextual factors, underlying mechanisms, and outcome configurations. ETHICS AND DISSEMINATION: As this study is a realist synthesis protocol, ethics approval is not required. Synthesis findings will be published in a peer-reviewed journal and presented at scientific conferences.

Clinical Practice Guideline by the Pediatric Infectious Diseases Society (PIDS) and the Infectious Diseases Society of America (IDSA): 2023 Guideline on Diagnosis and Management of Acute Bacterial Arthritis in Pediatrics.

This clinical practice guideline for the diagnosis and treatment of acute bacterial arthritis (ABA) in children was developed by a multidisciplinary panel representing the Pediatric Infectious Diseases Society (PIDS) and the Infectious Diseases Society of America (IDSA). This guideline is intended for use by healthcare professionals who care for children with ABA, including specialists in pediatric infectious diseases and orthopedics. The panel's recommendations for the diagnosis and treatment of ABA are based upon evidence derived from topic-specific systematic literature reviews. Summarized below are the recommendations for the diagnosis and treatment of ABA in children. The panel followed a systematic process used in the development of other IDSA and PIDS clinical practice guidelines, which included a standardized methodology for rating the certainty of the evidence and strength of recommendation using the GRADE approach (Grading of Recommendations Assessment, Development and Evaluation) (see Figure 1). A detailed description of background, methods, evidence summary and rationale that support each recommendation, and knowledge gaps can be found online in the full text.

Implementation and Evaluation of a Nurse Practitioner Onboarding Program at a Large Healthcare Facility.

A comprehensive, evidence-based onboarding program benefits healthcare workers and institutions. Many institutions do not have onboarding programs for new nurse practitioners (NPs). In this quality improvement initiative, a standardized onboarding program was developed. The impact on NP satisfaction and retention was evaluated. Lead NPs were identified as program managers. Program components included role introduction, competency validation, review of administrative essentials, ongoing progress logs, and program evaluations. The program resulted in increased NP satisfaction and retention.

Establishing thresholds for cytokine storm and defining their relationship to disease severity in respiratory viral infections.

Previous studies have identified cytokines associated with respiratory virus infection illness outcome. However, few studies have included comprehensive cytokine panels, longitudinal analyses, and/or simultaneous assessment across the severity spectrum. This, coupled with subjective definitions of cytokine storm syndrome (CSS), have contributed to inconsistent findings of cytokine signatures, particularly with COVID severity. Here, we measured 38 plasma cytokines and compared profiles in healthy, SARS-CoV-2 infected, and multisystem inflammatory syndrome in children (MIS-C) patients (n = 169). Infected patients spanned the severity spectrum and were classified as Asymptomatic, Mild, Moderate or Severe. Our results showed acute cytokine profiles and longitudinal dynamics of IL1Ra, IL10, MIP1b, and IP10 can differentiate COVID severity groups. Only 4% of acutely infected patients exhibited hypercytokinemia. Of these subjects, 3 were Mild, 3 Moderate, and 1 Severe, highlighting the lack of association between CSS and COVID severity. Additionally, we identified IL1Ra and TNFa as potential biomarkers for patients at high risk for long COVID. Lastly, we compare hypercytokinemia profiles across COVID and influenza patients and show distinct elevated cytokine signatures, wherein influenza induces the most elevated cytokine profile. Together, these results identify key analytes that, if obtained at early time points, can predict COVID illness outcome and/or risk of complications, and provide novel insight for improving the conceptual framework of hypercytokinemia, wherein CSS is a subgroup that requires concomitant severe clinical manifestations, and including a list of cytokines that can distinguish between subtypes of hypercytokinemia.

Association of Radiology Findings with Etiology of Community Acquired Pneumonia among Children.

OBJECTIVE: To evaluate the association between consolidation on chest radiograph and typical bacterial etiology of childhood community acquired pneumonia (CAP) in the Etiology of Pneumonia in the Community study. STUDY DESIGN: Hospitalized children <18 years of age with CAP enrolled in the Etiology of Pneumonia in the Community study at 3 children's hospitals between January 2010 and June 2012 were included. Testing of blood and respiratory specimens used multiple modalities to identify typical and atypical bacterial, or viral infection. Study radiologists classified chest radiographs (consolidation, other infiltrates [interstitial and/or alveolar], pleural effusion) using modified World Health Organization pneumonia criteria. Infiltrate patterns were compared according to etiology of CAP. RESULTS: Among 2212 children, there were 1302 (59%) with consolidation with or without other infiltrates, 910 (41%) with other infiltrates, and 296 (13%) with pleural effusion. In 1795 children, at least 1 pathogen was detected. Among these patients, consolidation (74%) was the most frequently observed pattern (74% in typical bacterial CAP, 58% in atypical bacterial CAP, and 54% in viral CAP). Positive and negative predictive values of consolidation for typical bacterial CAP were 12% (95% CI 10%-15%) and 96% (95% CI 95%-97%) respectively. In a multivariable model, typical bacterial CAP was associated with pleural effusion (OR 7.3, 95% CI 4.7-11.2) and white blood cell ≥15 000/mL (OR 3.2, 95% CI 2.2-4.9), and absence of wheeze (OR 0.5, 95% CI 0.3-0.8) or viral detection (OR 0.2, 95% CI 0.1-0.4). CONCLUSIONS: Consolidation predicted typical bacterial CAP poorly, but its absence made typical bacterial CAP unlikely. Pleural effusion was the best predictor of typical bacterial infection, but too uncommon to aid etiology prediction.

Early Intravenous Magnesium Sulfate Administration in the Emergency Department for Severe Asthma Exacerbations.

BACKGROUND: Severe asthma exacerbations in pediatric patients occur frequently and can require pediatric intensive care unit (PICU) admission. OBJECTIVE: To determine if early administration of intravenous magnesium sulfate (IVMg) to pediatric patients experiencing severe asthma exacerbations, defined as a respiratory clinical score (RCS) of 9 to 12, resulted in fewer PICU admissions. METHODS: Retrospective chart review of pediatric patients aged from 2 to 17 years presenting with a severe asthma exacerbation to a single tertiary care pediatric emergency department. Univariable and multivariable logistic regression analyses were used to determine if admission to the PICU was associated with early IVMg treatment, within 60 minutes of registration. RESULTS: A total of 1911 patients were included in the study, of which 1541 received IVMg. The average time to IVMg was 79 minutes, with 35% of the patients receiving it within 60 minutes of arrival. Two hundred forty-eight (13%) were admitted to the PICU, 641 (34%) were admitted to the general inpatient floor, and 1022 (53%) were discharged home. Factors associated with increased odds ratio (OR) of PICU admission were: early IVMg (OR, 1.63; 95% CI: 1.16-2.28), arrival mode to the emergency department via ambulance (OR, 2.23; 95% CI: 1.45-3.43), history of PICU admission for asthma (OR, 1.73; 95% CI: 1.22-2.44), and diagnosis of status asthmaticus (OR, 8.88; 95% CI: 3.49-30.07). Calculated OR of PICU admission subcategorized by RCS for early IVMg patients, after controlling for PICU risk factors, are as follows: RCS 9 (reference), RCS 10 (OR, 2.52; 95% CI: 0.89-2.23), RCS 11 (OR, 2.19; 95% CI: 1.3-3.70), and RCS 12 (OR, 4.12; 95% CI: 2.13-7.95). CONCLUSIONS: Early administration of IVMg to pediatric patients experiencing severe asthma exacerbations does not result in fewer PICU admissions.

Variation and Outcomes of Hospital-Level High-Flow Nasal Cannula Usage Outside of Intensive Care.

OBJECTIVES: Bronchiolitis is a viral respiratory infection that can progress to acute respiratory failure. This study evaluated the variability of hospital-wide high-flow nasal cannula (HFNC) usage outside of the ICU and its association with length of stay (LOS) and cost among pediatric patients admitted with bronchiolitis. METHODS: This study included patients <2 years old admitted with bronchiolitis between September 1, 2018 and March 31, 2019. Hospitals were divided into groups based on the proportion of patients among those who had never been in the ICU who received HFNC (non-ICU HFNC usage [NIHU]). We performed hierarchical mixed-model linear regression to estimate the association of NIHU with LOS and cost using multiplicative ratios (MR) and 95% confidence intervals (CI), both (1) unadjusted and (2) after adjusting for demographics, clinical characteristics, and individual utilization of HFNC and/or ICU. RESULTS: Unadjusted LOS was longer for patients in moderate (MR 1.14; 95% CI 1.11-1.18) and high (MR 1.26; 95% CI 1.22-1.30) NIHU hospitals. Adjusted LOS was longer in moderate (MR 1.03; 95% CI 1.01-1.06), and high (MR 1.08; 95% CI 1.05-1.11) NIHU hospitals. Unadjusted total cost was higher for patients in moderate (MR 1.20; 95% CI 1.16-1.25) and high (MR 1.26; 95% CI 1.22-1.31) NIHU hospitals. Adjusted total cost was higher for patients in moderate (MR 1.05; 95% CI 1.03-1.08), and high (MR 1.05; 95% CI 1.02-1.08) NIHU hospitals. CONCLUSIONS: In this study, increased NIHU is associated with increased LOS and total cost.

Red Blood Cell Distribution Width and Pediatric Community-Acquired Pneumonia Disease Severity.

BACKGROUND AND OBJECTIVES: No standardized risk assessment tool exists for community-acquired pneumonia (CAP) in children. This study aims to investigate the association between red blood cell distribution width (RDW) and pediatric CAP. METHODS: Data prospectively collected by the Etiology of Pneumonia in the Community study (2010-2012) was used. Study population was pediatric patients admitted to tertiary care hospitals in Nashville and Memphis, Tennessee with clinically and radiographically confirmed CAP. The earliest measured RDW value on admission was used, in quintiles and also as a continuous variable. Outcomes analyzed were: severe CAP (requiring ICU, mechanical ventilation, vasopressor support, or death) or moderate CAP (hospital admission only). Analysis used multivariable logistic regression and restricted cubic splines modeling. RESULTS: In 1459 eligible children, the median age was 29 months (interquartile range: 12-73), median RDW was 13.3% (interquartile range: 12.5-14.3), and 289 patients (19.8%) developed severe disease. In comparison with the lowest RDW quintile (Q1), the adjusted odds ratio (95% CI) for severe CAP in subsequent quintiles were, Q2: 1.20 (0.72-1.99); Q3: 1.28 (0.76-2.14); Q4: 1.69 (1.01-2.82); Q5: 1.25 (0.73-2.13). Consistently, RDW restricted cubic splines demonstrated an independent, nonlinear, positive association with CAP severity (P = .027), with rapid increases in the risk of severe CAP with RDW values up to 15%. CONCLUSIONS: Higher presenting RDW was associated with an increased risk of severe CAP in hospitalized children. Widely available and inexpensive, RDW can serve as an objective data point to help with clinical assessments.

Management of Histoplasmosis by Infectious Disease Physicians.

Background: The Infectious Diseases Society of America (IDSA) guidelines for the management of histoplasmosis were last revised 15 years ago. Since those guidelines were compiled, new antifungal treatment options have been developed. Furthermore, the ongoing development of immunomodulatory therapies has increased the population at increased risk to develop histoplasmosis. Methods: An electronic survey about the management practices of histoplasmosis was distributed to the adult infectious disease (ID) physician members of the IDSA's Emerging Infections Network. Results: The survey response rate was 37% (551/1477). Only 46% (253/551) of respondents reported seeing patients with histoplasmosis. Regions considered endemic had 82% (158/193) of physicians report seeing patients with histoplasmosis compared to 27% (95/358) of physicians in regions not classically considered endemic (P < 0.001). Most ID physicians follow IDSA treatment guidelines recommending itraconazole for acute pulmonary (189/253 [75%]), mild-moderate disseminated (189/253 [75%]), and as step-down therapy for severe disseminated histoplasmosis with (232/253 [92%]) and without (145/253 [57%]) central nervous system involvement. There were no consensus recommendations observed for survey questions regarding immunocompromised patients. Conclusions: Though there are increased reports of histoplasmosis diagnoses outside regions classically considered endemic, a majority of ID physicians reported not seeing patients with histoplasmosis. Most respondents reported adherence to IDSA guidelines recommending itraconazole in each clinical situation. New histoplasmosis guidelines need to reflect the growing need for updated general guidance, particularly for immunocompromised populations.

Utility of Induced Sputum in Assessing Bacterial Etiology for Community-Acquired Pneumonia in Hospitalized Children.

BACKGROUND: Diagnostic testing for bacterial etiology of community-acquired pneumonia (CAP) is insensitive. Induced sputum (IS) is an attractive option for the evaluation of the lower respiratory tract. METHODS: Children aged 0-18 years with CAP were enrolled in the Etiology of Pneumonia in the Community (EPIC) study between 2010 and 2012. Blood and respiratory specimens were assessed by culture and polymerase chain reaction (PCR). The radiographic CAP was determined by a study radiologist. Sputum was induced with hypertonic saline. IS specimen was high quality (HQ) if Gram stain showed >25 white blood and <10 epithelial cells per low-powered field; all others were low quality (LQ). We compared IS pathogen prevalence between HQ and LQ IS, and by radiographic pneumonia. Pathogen concordance with EPIC etiology was assessed. Length of stay (LOS) was compared by receipt of IS pathogen-concordant antibiotics. RESULTS: Out of 977 children, 916 (94%) children enrolled in Memphis, Tennessee, produced IS; 794 (87%) had radiographic CAP and 174 (19%) were HQ. HQ IS yielded pathogenic bacteria more often than LQ (64% vs 44%; P < .01); however, pathogens were isolated at similar rates in HQ IS in patients with and without radiographic CAP (64% vs. 63%; P = .6). Pathogens from study specimens matched an IS pathogen in only 9/42 (21%) patients with radiographic CAP. Median LOS was similar among patients with radiographic CAP regardless of receipt of IS pathogen-concordant antibiotics (3.1 days), non-pathogen-concordant antibiotics (2.7 days), or no antibiotics (3.2 days; P = .5). CONCLUSIONS: Bacterial pathogens were isolated from most IS cultures regardless of radiographic CAP and quality of IS. IS cultures infrequently corresponded with sterile site cultures. Isolation of pathogens from pediatric IS reflects oropharyngeal carriage and is insufficient to determine bacterial etiology of CAP.

How Broad Should Gram-Negative Coverage Be for Febrile Parenteral Nutrition Dependent Short Bowel Syndrome Patients?

ABSTRACT: Broader spectrum Gram-negative antibiotics are commonly utilized empirically for central line-associated bloodstream infections (CLABSI) in febrile short bowel syndrome (SBS) patients receiving home parenteral nutrition compared to those used empirically for inpatient-acquired CLABSI. This analysis reports 57 CLABSI in 22 patients with SBS admitted from the community and 78 inpatient-acquired CLABSI in 76 patients over a 5-year period. Proportional Gram-negative CLABSI was similar between the SBS and inpatient-acquired cohorts (43.8% vs42.3%, respectively, P  = 0.78). 1.8% and 10.3% (P = 0.125) of Gram-negative CLABSI were non-susceptible to ceftriaxone and 0% and 3.8% (P = 0.52) were non-susceptible to ceftazidime in the SBS and inpatient-acquired cohorts, respectively. In the SBS cohort, home ethanol lock therapy and prior culture results impacted Gramnegative pathogen distribution. Broader empiric Gram-negative coverage for CLABSI among SBS patients compared to inpatients is unnecessary. Third-generation cephalosporins represent appropriate empiric Gramnegative agents for febrile SBS patients presenting from the community to our institution.

Establishing a COVID-positive mental health ward: an Australian-first case study.

OBJECTIVE: Managing mental health patients during the COVID-19 pandemic has been a global challenge. Current workforce arrangements tend to separate those skilled in caring for highly infectious medical patients from those whose specialism is in managing co-morbid mental health, substance misuse and/or behaviours of concern, including potential non-compliance with community or health care directives. This paper reports an innovative service development through the emergency establishment of a temporary COVID-positive mental health ward in response to a local outbreak in Melbourne. METHOD: A case study of service reorientation is presented, examining barriers and enablers to effective care of co-morbid mental illness, addiction and COVID-19. RESULTS: Establishing a skilled multidisciplinary workforce across mental health and infectious disease is the most important consideration in optimising care. Other issues included suitable physical space, security arrangements and inter-disciplinary communication. CONCLUSIONS: The paper holds insights for managing mental health care during potential future infectious disease outbreaks across the country.

Analysis of Community-Acquired Urinary Tract Infection Treatment in Pediatric Patients Requiring Hospitalization: Opportunity for Use of Narrower Spectrum Antibiotics.

Background: The most narrow-spectrum antibiotic possible should be used for empiric and definitive treatment of pediatric urinary tract infections (UTIs). Objectives: The objectives of this study were to determine an appropriate narrow-spectrum antibiotic for empiric UTI treatment, factors differentiating empiric first-generation cephalosporin (FGC) versus third-generation cephalosporin (TGC) coverage, and factors associated with unnecessarily broad-spectrum definitive antibiotic treatment. Methods: This was a retrospective chart review of children admitted from 2013 to 2015 who were diagnosed with a UTI and received treatment. Multivariable logistic regression assessed independent factors associated with our outcomes. Results: Of 568 diagnosed UTIs, 88.6% received empiric TGC treatment. Empiric coverage among cultured organisms was only 5.4% lower in FGC versus TGC. Adolescent age group (odds ratio [OR] = 8.83, 95% confidence interval [CI] = 1.47-53.11), uncircumcised males (OR = 4.52, 95% CI = 1.27-16.08), Hispanic ethnicity (OR = 4.37, 95% CI = 1.14-16.82), and hospitalization within the preceding 3 months (OR = 4.73, 95% CI = 1.38-16.23) were associated with FGC nonsusceptibility among TGC susceptible Enterobacteriaceae pathogens. De-escalation occurred in 55.8% of diagnosed UTIs eligible for de-escalation at discharge. Urine white blood cell (WBC) count >5 (OR = 2.89, 95% CI = 1.14-7.21), serum WBC count (OR = 1.04, 95% CI = 1.01-1.07), and having only one narrow-spectrum treatment option (OR = 5.1, 95% CI = 2.43-10.66) were associated with unnecessarily broad-spectrum definitive treatment. Conclusion and Relevance: FGC would be an appropriate narrow-spectrum empiric agent for UTIs at our institution. The factors associated with FGC nonsusceptibility can further stratify empiric treatment decisions. The factors associated with unnecessarily broad-spectrum definitive treatment illustrate areas for educational efforts and future research regarding UTI treatment.

A Culture Change: Impact of a Pediatric Antimicrobial Stewardship Program Based on Guideline Implementation and Prospective Audit with Feedback.

Reports analyzing the impact of pediatric antimicrobial stewardship programs (ASP) over long periods of time are lacking. We thus report our ASP experience in a pediatric tertiary referral center over a long-term period from 2011 to 2018. Our ASP was implemented in 2011. The program was based primarily on guideline development with key stakeholders, engaging and educating providers, followed by prospective audit with feedback (PAF). Monitored antibiotics included meropenem, piperacillin-tazobactam, and cefepime, followed by the addition of ceftriaxone, ceftazidime, cefotaxime, ciprofloxacin, levofloxacin, linezolid, and vancomycin at various time points. Specifically, the program did not implemented the core strategy of formulary restriction with prior authorization. Process- and outcome-related ASP measures were analyzed. We saw a 32% decrease in overall antibiotic utilization, a 51% decrease in the utilization of antibiotics undergoing PAF, and a 72% reduction in the use of broad-spectrum antibiotics such as meropenem. There was a concomitant increase in organism susceptibility and a reduction in yearly drug purchasing costs of over USD 560,000 from baseline without changes in sepsis-related mortality. Our study highlights that a pediatric ASP based primarily on the principles of guideline development and PAF can improve antibiotic utilization and institutional bacterial susceptibilities without a detrimental impact on patient outcomes by changing the culture of antimicrobial utilization within the institution.

Clinical Practice Guideline by the Pediatric Infectious Diseases Society and the Infectious Diseases Society of America: 2021 Guideline on Diagnosis and Management of Acute Hematogenous Osteomyelitis in Pediatrics.

This clinical practice guideline for the diagnosis and treatment of acute hematogenous osteomyelitis (AHO) in children was developed by a multidisciplinary panel representing Pediatric Infectious Diseases Society (PIDS) and the Infectious Diseases Society of America (IDSA). This guideline is intended for use by healthcare professionals who care for children with AHO, including specialists in pediatric infectious diseases, orthopedics, emergency care physicians, hospitalists, and any clinicians and healthcare providers caring for these patients. The panel's recommendations for the diagnosis and treatment of AHO are based upon evidence derived from topic-specific systematic literature reviews. Summarized below are the recommendations for the diagnosis and treatment of AHO in children. The panel followed a systematic process used in the development of other IDSA and PIDS clinical practice guidelines, which included a standardized methodology for rating the certainty of the evidence and strength of recommendation using the GRADE (Grading of Recommendations Assessment, Development and Evaluation) approach. A detailed description of background, methods, evidence summary and rationale that support each recommendation, and knowledge gaps can be found online in the full text.

Particulate matter exposure predicts residence in high-risk areas for community acquired pneumonia among hospitalized children.

Particulate matter exposure is a risk factor for lower respiratory tract infection in children. Here, we investigated the geospatial patterns of community-acquired pneumonia and the impact of PM2.5 (particulate matter with an aerodynamic diameter ≤2.5 µm) on geospatial variability of pneumonia in children. We performed a retrospective analysis of prospectively collected population-based surveillance study data of community-acquired pneumonia hospitalizations among children <18 years residing in the Memphis metropolitan area, who were enrolled in the Centers for Disease Control and Prevention sponsored Etiology of Pneumonia in the Community (EPIC) study from January 2010 to June 2012. The outcome measure, residence in high- and low-risk areas for community-acquired pneumonia, was determined by calculating pneumonia incidence rates and performing cluster analysis to identify areas with higher/lower than expected rates of community-acquired pneumonia for the population at risk. High PM2.5 was defined as exposure to PM2.5 concentrations greater than the mean value (>10.75 µg/m3), and low PM2.5 is defined as exposure to PM2.5 concentrations less than or equal to the mean value (≤10.75 µg/m3). We also assessed the effects of age, sex, race/ethnicity, history of wheezing, insurance type, tobacco smoke exposure, bacterial etiology, and viral etiology of infection. Of 810 (96.1%) subjects with radiographic community-acquired pneumonia, who resided in the Memphis metropolitan area and had addresses which were successfully geocoded (Supplementary Figure F2), 220 (27.2%) patients were identified to be from high- (n = 126) or low-risk (n = 94) community-acquired pneumonia areas. Community-acquired pneumonia in Memphis metropolitan area had a non-homogenous geospatial pattern. PM2.5 was associated with residence in high-risk areas for community-acquired pneumonia. In addition, children with private insurance and bacterial, as opposed to viral, etiology of infection had a decreased risk of residence in a high-risk area for community-acquired pneumonia. The results from this paper suggest that environmental exposures as well as social risk factors are associated with childhood pneumonia.

Lemierre's Syndrome Due to the Zoonotic Anaerobe Bacteroides pyogenes: Case Report and Literature Review.

Although Fusobacterium necrophorum is well described as an emerging pathogen of acute mastoiditis in young children, infection with other anaerobes can lead to similar severe sequelae including intracranial and extracranial suppurative thrombophlebitis and sepsis. We describe a patient whose unremarkable exposure history assumed increased significance upon obtaining the results of 16S next generation sequencing from a surgical specimen. The novel pathogen Bacteroides pyogenes is reviewed herein.
