Abstract Background: Pediatric hospital-acquired venous thromboembolism (HA-VTE) incidence is rising and many centers are instituting pediatric-specific prophylaxis programs despite a lack of evidence-based risk stratification to reduce unnecessary thromboprophylaxis exposure. Objectives: The multi-institutional Children's Hospital-Acquired Thrombosis (CHAT) Registry via Research Electronic Data Capture (REDCap) can identify independent HA-VTE risk factors for prospective validation and creation of a risk-assessment scoring system. Methods: This IRB-approved, retrospective registry reveals HA-VTE risk factors from subjects aged 0-21 years with radiographically-validated VTE ≥ 48 hours after hospital admission, or after central venous line placement, at 5 pediatric hospitals from January 2012 - June 2015. Descriptive statistics summarize demographics, medical comorbidities, characteristics of the VTEs themselves and associated laboratory testing for 555 subjects. Further analyses are currently utilizing matched controls and logistic regression to identify specific odds ratios for independent risk factors. Results: The median time to VTE diagnosis was 9 days with interquartile range (IQR) of 5-18.5 days, 34% of VTE occurred in a critical care unit, and 36.8% of subjects had been hospitalized in the 30 days prior to the index hospitalization. 22.7% of VTE events were incidentally found. VTE distribution was: deep vein thromboses of arms/legs (79.6%), cerebral sinus venous thrombosis (7%), abdominal VTE (5%), pulmonary embolism (4.3%), and other (intra-cardiac and superior vena cava/right atrial junction - 5.5%) with overlap due to some subjects with multiple, separate, concurrent VTE events. Demographic characteristics revealed median age of 3.6 years (IQR: 0.4 - 13.6 years) at VTE diagnosis and slight male predominance (55%). 66.1% of subjects had significant past medical history (Table 1) and 7.2% were immobile at baseline. Evaluation of hospital course revealed a multitude of acquired putative risk factors for HA-VTE (Table 2). 70.8% of VTE were associated with a central venous catheter (CVC). Of CVC-related VTE, 70.5% were in the same vein as CVC, 20.1% were in a vein which previously held a CVC, 10.7% surrounded the CVC tip, 2.5% occurred in a vein where CVC placement was attempted but unsuccessful. 55% of subjects had at least one documented infection during hospitalization, 42% of subjects had surgery, 20.7% had a procedure involving intravascular instrumentation (defined as dialysis, plasmapheresis, cardiac catheterization, stent placement/removal, or coiling procedure), 5% of subjects underwent trauma prior to admission with 82% of trauma classified as "major", and 59.5% of subjects were intubated at some point during their admission. Regarding medications, 31.9% of subjects were on steroids at VTE diagnosis and an additional 13.2% of subjects received steroids in the 30 days prior to VTE diagnosis, 2.2% of subjects were on estrogen with all of these subjects having started estrogen within 6 months prior to VTE diagnosis, 4.1% of subjects received asparaginase prior to VTE, 1.6% of subjects received recombinant factor VIIa prior to VTE, and 0.4% of subjects received prothrombin complex concentrates prior to VTE. Laboratory testing of hospitalized patients revealed 43.2% of patients had a d-dimer level obtained at time of VTE and 96.5% of those patients had an elevated level. 48.3% of patients had at least one thrombophilia lab test ordered. 17.8% of subjects received VTE prophylaxis - 55% of which was pharmacologic anticoagulation. Conclusions: The CHAT registry results demonstrate a slight male predisposition and multiple associated chronic medical illnesses and acquired hospital course co-morbidities, particularly CVCs which were involved in the majority of events. Ongoing work includes incorporating additional institutions to reach a goal of 1000 cases and 2000 controls to identify independent risk factors for the development of a risk-assessment scoring system. Long-term goals include prospective validation of the scoring system to serve as the basis of identifying subjects for a future randomized clinical trial of risk-based prevention strategies. Such a trial would evaluate efficacy, safety, and cost-benefit of thromboprophylaxis in hospitalized children and help inform best practices.

Abstract Background: Pediatric hospital-acquired venous thromboembolism (HA-VTE) incidence is rising but remains relatively low overall, requiring risk stratification to reduce unnecessary thromboprophylaxis exposure. Large sample sizes are needed for prospective epidemiologic risk factor studies, necessitating collaboration. Objectives: We formed the multi-institutional Children's Hospital-Acquired Thrombosis (CHAT) web-based registry via Research Electronic Data Capture (REDCap) to identify independent HA-VTE risk factors for future clinical risk score development. Methods: This IRB-approved, retrospective chart review reveals HA-VTE risk factors from patients aged 0-21 years who developed diagnostically-validated VTE more than 48 hours after hospital admission, or after central venous line placement, at 3 pediatric hospitals from January 2012 - December 2014. We used descriptive statistics to summarize demographics, medical comorbidities and types of any applicable central lines for the initial 373 patients entered into the database, as well as characteristics of the VTEs themselves and associated laboratory testing. Further analysis is currently underway utilizing matched controls and logistic regression to identify specific odds ratios for independent risk factors. Results: The median length of time to VTE diagnosis was 9 with interquartile range (IQR) of day 4-18, 35.3% of VTE occurred in a critical care unit, and 21% were incidentally found. The distribution of VTE included deep vein thromboses (DVT) of the arms/legs (81.1%) followed by cerebral sinus venous thrombosis (7.3%), pulmonary embolism (5.4%), DVT of the abdomen (4%), and intracardiac DVT (4%) with some overlap due to patients with multiple, separate, concurrent VTE events. Demographic characteristics of the initial 373 subjects revealed median age of 3.7 years (IQR of 0.4 years to 13.8 years) at VTE diagnosis and a slight male predominance (57.4%). 62.6% of patients had significant past medical history (Figure 1) and 8% were immobile at baseline. Evaluation of hospital course revealed a multitude of acquired putative risk factors for HA-VTE (Figure 2). 75.7% of VTE were associated with a central venous catheter (CVC). Of CVC-related VTE, 72% were in the same vein as CVC, 20% were in a vein which previously held a CVC, 3.6% surrounded the CVC tip, 2.9% occurred in a vein where CVC placement was attempted but unsuccessful. 59% of patients had at least one documented infection during hospitalization, 48% of patients had surgery, 5.5% of patients underwent trauma prior to admission, and 59.7% (n=221) of patients were intubated at some point during their admission with 86.9% (n=192) of those patients developing VTE after a minimum of 24 hours of mechanical ventilation. Laboratory testing of hospitalized patients revealed 51.2% of patients had a d-dimer level obtained at time of VTE and 97.8% of those patients had an elevated level. 44% of patients had at least one thrombophilia lab test ordered. Conclusions: The initial CHAT database results demonstrate a slight male predisposition and multiple associated chronic medical illnesses and acquired hospital course co-morbidities, particularly CVCs which were involved in three-fourths of VTE events. Ongoing work includes incorporating additional institutions and utilizing control subjects to identify independent risk factors for the development of a risk score model. Long-term goals include prospective validation of the scoring system in a cohort of patients from pediatric centers not involved in development of the risk score with the ultimate plan of using the scoring system to stratify patients for future randomized clinical trials of risk-based prevention strategies to evaluate the safety and efficacy of this approach for reduction of pediatric HA-VTE incidence without unnecessary thromboprophylaxis exposure.

Introduction: The incidence of venous thromboembolism (VTE) in hospitalized pediatric patients is increasing secondary to the growing medical complexity of pediatric patients and the increasing use of central venous catheters. Pediatric patients diagnosed with VTE have up to 2% mortality associated directly with their thromboses. While incidence, risk factor identification and preventive strategies are well established in hospitalized adults, this information is limited in the pediatric population. There are currently no standardized VTE risk screening tools or thromboprophylaxis guidelines for children at Duke Children's Hospital. The incidence of hospital acquired VTE (HA-VTE), as well as their associated risk factors were investigated in a retrospective review. Methods: Medical records of pediatric patients hospitalized at Duke Children's Hospital during June 2018 through November 2018 were reviewed. The EPIC SlicerDicer tool was used to identify patients with ICD-10 diagnoses codes related to thrombosis or treated with anticoagulants. Included patients were diagnosed with HA-VTE during their hospitalization or within 14 days of discharge. Data collected included demographics, thrombosis characteristics, family history, mobility, and acute or chronic co-morbid conditions. The characteristics of the study population were described by median (with 25th and 75th percentiles) for continuous variables and frequencies (with percentages) for binary or categorical variables. Results: Out of 4,176 total pediatric admissions to all units of Duke Children's Hospital (ages 0-18.99 years) during the inclusion timeframe, 33 VTE events were identified. The incidence of VTE events per 1000 patient days was 0.98. The complete patient and VTE event characteristics are listed in Tables 1 and 2. The median age of patients with VTE events was 0.4 years. Of the identified cohort, 73% had an associated central venous line (CVL). Neonates with congenital cardiac disease comprised the majority of the cohort. Other common patient characteristics observed in this cohort included impaired mobility, recent major surgery, and recent mechanical ventilation. Of the 33 VTE diagnoses, 70% received therapeutic anticoagulation with enoxaparin or unfractionated heparin. Only 2 patients (8%) received prophylactic anticoagulation prior to their diagnosis of VTE. Conclusions: The retrospective review of HA-VTE events at Duke Children's Hospital identified that the majority of the events occurred in neonates with congenital cardiac disease and the presence of CVLs. It was also noted that there was no standardization among the use of anticoagulation agents that were initiated for treatment of VTE. Furthermore, few patients received VTE prophylaxis during the hospitalization. A limitation of this review was that it was retrospective and the documentation of family history of thrombosis was inconsistent. It is also possible that several VTE events were missed due to inadequate ICD-10 coding. Based on the results of this review, there is a need to implement a risk stratification tool and develop standardized recommendations of VTE prophylaxis and treatments for pediatric patients admitted to Duke Children's Hospital. There is an additional quality improvement phase of this project and the goal is to implement a risk calculator that is based on information learned from the retrospective review. Ultimately, this risk calculator will help to decrease the incidence of VTE events at Duke Children's Hospital.

Abstract Introduction: Venous thromboembolism (VTE) rates in children are increasing, largely due to the improved care of critically ill children and the placement of central venous catheters (CVCs). There is limited evidence regarding risk factors for CVC-associated thrombosis, and there are no guidelines for pediatric patients on choosing catheter type, insertion technique or consideration for prophylaxis. This study aims to be the first prospective, observational, multi-center, pediatric study to compare the VTE incidence between peripherally inserted central catheters (PICCs) and centrally inserted tunneled lines (TLs), as well as identify additional risk factors for CVC-associated thrombosis. Methods: This prospective, observational cohort study enrolled patients aged 6 months to <18 years from 3 large pediatric hospitals, Children's Hospital Los Angeles, Children's Hospital of Philadelphia and Texas Children's Hospital between September 2013 to April 2016 who either had a PICC or TL placed. Data regarding subject demographics and medical history (cancer, congenital heart disease, history of VTE, current infection, etc.) were collected via electronic medical record (EMR) review. Details specific to the CVC (reason for insertion, CVC size, number of lumens, brand and CVC material) and insertion technique (length of CVC, vein accessed, number of attempts) were also collected. Subjects were then prospectively monitored for the occurrence of a VTE and other CVC-related complications (infection, malfunction, use of tissue plasminogen activator) via EMR review for up to 6 months after their CVC was placed or after diagnosis of a VTE. Univariable and multivariable logistic regression was utilized to examine the association of patient and CVC characteristics on VTE incidence. All significant predictors (p < 0.10) in the univariable analyses were entered into a multivariable model where each predictor's contribution was assessed. Results: Interim analysis includes 789 subjects [53% male, median age 6 years (0.5, 18)] who had 883 CVCs placed (Table 1). PICCs were placed in 570 (65%) subjects and 313 (35%) had TLs placed. There were a total of 43 CVC-related VTEs (4.9%) and the majority, 37 (86%), were in subjects with PICCs. The median time to develop a PICC-associated VTE after placement was 37 days (1, 215). Twenty-four predictors were analyzed in separate logistic regression models. Univariable analysis of twenty-four possible predictors revealed a statistically significant increased risk of VTE incidence in subjects with a history of VTE with an odds ratio (OR) of 2.9 [95% confidence interval (CI), 1.3-6.6] or congenital heart disease OR=2.8 (CI 1.3-6.0), subjects with PICCs (vs. TLs) OR=3.8 (CI 1.6-9.1), multiple lumen CVCs (TL or PICC) OR=3.2 (CI 1.7-6.0) or in CVCs with a malfunction OR=2.1 (1.1-3.9). Male gender, on the other hand, was associated with a reduced risk of VTE OR=0.46 (0.2-0.9). Type of CVC (PICC vs. TL) OR=3.4 (CI 1.4-8.2), number of lumens OR=2.7 (CI 1.5-5.3), and history of VTE OR=2.8 (CI 1.2-6.5) remained significant positive predictors of VTE incidence in the setting of a multivariable model. Male gender remained to be inversely associated with VTE incidence (Table 2). Conclusions: This is the first prospective pediatric study comparing VTE incidence in PICCs versus TLs. This interim analysis of nearly 800 subjects revealed a significantly higher risk of VTE in subjects who have had a PICC placed versus a TL. Due to their ease of insertion, PICCs are being placed at increasing rates in some pediatric centers, thus this finding may be the leading factor for the increasing pediatric VTE incidence. Other significant risk factors for VTE were patients with multiple lumen CVCs and a history of VTE. For children who require a new CVC, practitioners should consider avoiding PICCs and multiple lumen CVCs if possible. Consideration should also be made to give prophylactic anticoagulation for children with a CVC and a history of VTE. Further analysis will be performed concerning the decreased VTE rate in male patients. The identification of these risk factors is the first step to creating CVC selection and insertion guidelines for all children to prevent VTE. Continued subject recruitment, with the recent addition of Nationwide Children's Hospital, is occurring to complete this evaluation.

OBJECTIVE The goal of this study was to identify the independent risk factors for recurrence or progression of pediatric craniopharyngioma and to establish predictors of the appropriate timing of intervention and best management strategy in the setting of recurrence/progression, with the aim of optimizing tumor control. METHODS This is a retrospective cohort study of all pediatric patients with craniopharyngioma who were diagnosed and treated at Boston Children’s Hospital between 1990 and 2017. This study was approved by the institutional review board at Boston Children’s Hospital. All statistical analyses were performed using Stata software. RESULTS Eighty patients (43 males and 37 females) fulfilled the inclusion criteria. The mean age at the time of diagnosis was 8.6 ± 4.4 years (range 1.2–19.7 years). The mean follow-up was 10.9 ± 6.5 years (range 1.3–24.6 years). Overall, 30/80 (37.5%) patients developed recurrence/progression. The median latency to recurrence/progression was 12.75 months (range 3–108 months). Subtotal resection with no adjuvant radiotherapy (p < 0.001) and fine calcifications (p = 0.008) are independent risk factors for recurrence/progression. An increase (%) in the maximum dimension of the tumor at the time of recurrence/progression was considered a statistically significant predictor of the appropriate timing of intervention. CONCLUSIONS Based on the identified independent risk factors for tumor recurrence/progression and the predictors of appropriate timing of intervention in the setting of recurrence/progression, the authors propose an algorithm for optimal management of recurrent pediatric craniopharyngioma to increase the likelihood of tumor control.

Abstract Background Limited research has been published to describe the incidence of venous thromboembolism (VTE) and relevant risk factors in Canadian children with inflammatory bowel disease (IBD). Aims The present study aimed to investigate the incidence of VTE amongst hospitalized pediatric IBD patients over a 10-year period and identify risk factors for the development of VTE. Methods A retrospective, matched case-control study was performed at McMaster Children’s Hospital. Hospitalized pediatric patients with IBD (&lt;18 years old) from September 2009 to August 2020 were selected. Inpatient data was extracted from the medical record database, including baseline demographic data, thromboembolic events and potential risk factors for VTE. Results There were 890 hospitalizations of IBD patients during the study period. 15 (1.69%) were diagnosed with a VTE, including 4 males and 11 females (mean age 13.4±2.9 years old). 12 ulcerative colitis (UC) (80%) and 3 Crohn’s disease (CD) (20%) hospitalizations were comprised in the VTE group. There was a significant difference in VTE rate between females (2.7%) and males (0.8%) (P = 0.03). The VTE rate in the UC group (4.2%) was significantly higher than in the CD group (0.6%) (P = 0.001). The incidence of VTE amongst hospitalized IBD patients did not vary over the 10-year period (P = 0.496). Length of stay in hospital, albumin level and central venous catheter were shown to be significantly different, although they were not identified as independent risk factors (P &gt;0 .05). Of the 15 hospitalizations with VTE, 6/15 (40%) were superficial VTEs in the extremities and 9/15 (60%) had a deep vein thrombosis (DVT) including 6 in the extremities and 3 in the abdomen. VTEs were associated with a peripheral line in 7 patients and with a PICC line in 4 hospitalizations. 2 of 9 (22%) with extremity DVT developed symptomatic pulmonary embolism. An inherited thrombotic condition was identified in 2 of 15 with VTEs. 12/15 (80%) with VTEs were symptomatic and all VTE related symptoms happened in patients with extremity thrombosis and pulmonary embolism. 7 of 15 (47%) VTEs were treated with anticoagulation therapy for 1–6 months. VTE related symptoms and repeat imaging tests significantly improved, and no patient developed a bleeding complication as a result of treatment. Conclusions The VTE rate in pediatric IBD patients was relatively low at McMaster Children’s hospital. Children with VTE were disproportionately females with ulcerative colitis compared with children with no VTE. Central venous line insertion may be correlated with the risk for VTE in children with IBD. Most VTEs and related symptoms happened in patients with extremity thrombosis and secondary pulmonary embolus. Anticoagulation therapy in children with IBD with active disease appears to be safe.

<b><i>Background:</i></b> Thromboembolic events (TEEs) may significantly complicate the clinical management of patients with testicular germ cell tumours (GCTs). We analysed a cohort of GCT patients for the occurrence of TEEs and looked to possible pathogenetic factors. <b><i>Patients, Methods:</i></b> TEEs occurring within 6 months after diagnosis were retrospectively analysed in 317 consecutive patients with testicular GCT (median age 37 years, 198 seminoma, 119 nonseminoma). The following factors were analysed for association with TEE: histology, age, clinical stage (CS), chemotherapy, use of a central venous access device (CVA). Data analysis involved descriptive statistical methods with multivariable analysis to identify independent risk factors. <b><i>Results:</i></b> Twenty-three TEEs (7.3%) were observed, 18 deep vein thromboses, 4 pulmonary embolisms, and 1 myocardial infarction. Univariable risk calculation yielded the following odds ratios (ORs) : &#x3e;CS1 OR = 43.7 (95% confidence intervals [CIs] 9.9–191.6); chemotherapy OR = 7.8 (95% CI 2.3–26.6); CVA OR = 30.5 (95% CI 11.0–84.3). Multivariable analysis identified only CS &#x3e; 1 (OR = 16.9; 95% CI 3.5–82.4) and CVA (OR = 9.0; 95% CI 2.9–27.5) as independent risk factors. <b><i>Conclusions:</i></b> Patients with CSs &#x3e;CS1 are at significantly increased risk of TEEs even without chemotherapy. Particular high risk is associated with the use of CVA devices for chemotherapy. Caregivers of GCT patients must be aware of the particular risk of TEEs.

Abstract Bovine respiratory disease (BRD) is the leading natural cause of death in US beef and dairy cattle, causing the annual loss of more than 1 million animals and financial losses in excess of $700 million. The multiple etiologies of BRD and its complex web of risk factors necessitate a herd-specific intervention plan for its prevention and control on dairies. Hence, a risk assessment is an important tool that producers and veterinarians can utilize for a comprehensive assessment of the management and host factors that predispose calves to BRD. The current study identifies the steps taken to develop the first BRD risk assessment tool and its components, namely the BRD risk factor questionnaire, the BRD scoring system, and a herd-specific BRD control and prevention plan. The risk factor questionnaire was designed to inquire on aspects of calf-rearing including management practices that affect calf health generally, and BRD specifically. The risk scores associated with each risk factor investigated in the questionnaire were estimated based on data from two observational studies. Producers can also estimate the prevalence of BRD in their calf herds using a smart phone or tablet application that facilitates selection of a true random sample of calves for scoring using the California BRD scoring system. Based on the risk factors identified, producers and herd veterinarians can then decide the management changes needed to mitigate the calf herd's risk for BRD. A follow-up risk assessment after a duration of time sufficient for exposure of a new cohort of calves to the management changes introduced in response to the risk assessment is recommended to monitor the prevalence of BRD.

Hospital acquired pneumonia (HAP) is common and often associated with high mortality in children aged five or less. We sought to evaluate the risk factors and outcome of HAP in such children. We compared demographic, clinical, and laboratory characteristics in children <5 years using a case control design during the period of August 2013 and December 2017, where children with HAP were constituted as cases (n = 281) and twice as many randomly selected children without HAP were constituted as controls (n = 562). HAP was defined as a child developing a new episode of pneumonia both clinically and radiologically after at least 48 h of hospitalization. A total of 4101 children were treated during the study period. The mortality was significantly higher among the cases than the controls (8% vs. 4%, p = 0.014). In multivariate logistic regression analysis, after adjusting for potential confounders, it was found that persistent diarrhea (95% CI = 1.32–5.79; p = 0.007), severe acute malnutrition (95% CI = 1.46–3.27; p < 0.001), bacteremia (95% CI = 1.16–3.49; p = 0.013), and prolonged hospitalization of >5 days (95% CI = 3.01–8.02; p < 0.001) were identified as independent risk factors for HAP. Early identification of these risk factors and their prompt management may help to reduce HAP-related fatal consequences, especially in resource limited settings.
