Pediatric Dog Bites to the Face May Have Been Less Severe During COVID-19 Pandemic: A Retrospective Cohort Study.

PURPOSE: Pediatric dog bite injuries are one of the most common nonfatal injuries. During the COVID-19 pandemic, children stayed at home more than pre-pandemic. The effect of the pandemic on severity of dog bites to the face in children has not been examined. The objective of this study was to determine the frequency and severity of dog bite injuries to the face in children during the first year of the COVID-19 pandemic when compared to the previous year. MATERIALS AND METHODS: A retrospective cohort study was conducted for children with dog bite injuries to the head and neck region who presented to the emergency department at Children's Healthcare of Atlanta from March 2019 to March 2021. The predictor variable was the time of injury, and this was divided into pre-lockdown [control group (March 15, 2019, to March 15, 2020), ie pre-L] and lockdown (March 15, 2019, to March 15, 2020), ie post-L. The outcome variable was severity of dog bite defined as one or more of the following: 1) patient required sedation or general anesthesia for repair, 2) 3 or more regions in the head and neck were involved, and/or 3) surgical consultation took place. The investigators used a two-sample t-test, multivariable linear regression models, and modified analysis of variance and multivariate ANOVA tests to analyze the data (P-value < .05 determined significance). RESULTS: 712 children (370 males) with an average age of 6 years old (range, 7 months-18 years) fit the inclusion criteria. There were 381 cases in the pre-L and 331 in the post-L period. There were more cases on average per month pre-L (31.8 cases/month) than post-L (27.6 cases/month) (P-value = .26). There were 183 pre-L surgical consults compared to 75 post-L (48 vs 22.8% of cases, respectively; P-value ≤ .001). There were 52 pre-L cases that had 3 or more sites in the head and neck compared to 28 during the post-L period (P-value = .032). CONCLUSIONS: During the COVID-19 pandemic, there may have been a decrease in the severity of dog bite injuries. This trend may demonstrate a consequence that is not a direct result of the virus.

Correlation between imaging findings on outpatient MR enterography (MRE) in adult patients with Crohn disease and progression to surgery within 5 years.

PURPOSE: To retrospectively evaluate which key imaging features described by SAR-AGA on outpatient surveillance MRE correlate with progression to surgery in adults with CD. METHODS: 52 CD patients imaged with outpatient MRE from 10/2015 to 12/2016 and with available clinical information were included. Two abdominal radiologists reviewed the MRE for the presence of active inflammation, intramural edema, restricted diffusion, stricture, probable stricture, ulceration, sacculation, simple fistula, complex fistula, sinus tract, inflammatory mass, abscess, perienteric inflammation, engorged vasa recta, fibrofatty proliferation, and perianal disease. Bowel wall thickness, length of bowel involvement, and degree of upstream dilation in strictures were quantified. Subsequent bowel resection, prior bowel surgery, and available laboratory values were recorded. The association between progression to surgery and imaging features was evaluated using a logistic regression model adjusting for demographics, prior bowel surgery, medication usage, and body mass index. RESULTS: 19.2% (10/52) of patients progressed to surgery. Restricted diffusion, greater degree of upstream dilation from stricture, complex fistula, perienteric inflammation, and fibrofatty proliferation were significantly more common in patients progressing to surgery (all p < 0.05). κ for these significant findings ranged 0.568-0.885. Patients progressing to surgery had longer length bowel involvement (p = 0.03). Platelet count, ESR, and fecal calprotectin were significantly higher, and serum albumin was significantly lower in patients progressing to surgery. Prior bowel surgery, sex, age, and all other parameters were similar. CONCLUSION: Radiologists should carefully describe bowel dilation upstream from strictures, penetrating and perienteric findings on outpatient MRE in CD patients, as these findings may herald progression to surgery.

Association of body composition parameters measured on CT with risk of hospitalization in patients with Covid-19.

PURPOSE: To assess prognostic value of body composition parameters measured at CT to predict risk of hospitalization in patients with COVID-19 infection. METHODS: 177 patients with SARS-CoV-2 infection and with abdominopelvic CT were included in this retrospective IRB approved two-institution study. Patients were stratified based on disease severity as outpatients (no hospital admission) and patients who were hospitalized (inpatients). Two readers blinded to the clinical outcome segmented axial CT images at the L3 vertebral body level for visceral adipose tissue (VAT), subcutaneous adipose tissue (SAT), muscle adipose tissue (MAT), muscle mass (MM). VAT to total adipose tissue ratio (VAT/TAT), MAT/MM ratio, and muscle index (MI) at L3 were computed. These measures, along with detailed clinical risk factors, were compared in patients stratified by severity. Various logistic regression clinical and clinical + imaging models were compared to discriminate inpatients from outpatients. RESULTS: There were 76 outpatients (43%) and 101 inpatients. Male gender (p = 0.013), age (p = 0.0003), hypertension (p = 0.0003), diabetes (p = 0.0001), history of cardiac disease (p = 0.007), VAT/TAT (p < 0.0001), and MAT/MM (p < 0.0001), but not BMI, were associated with hospitalization. A clinical model (age, gender, BMI) had AUC of 0.70. Addition of VAT/TAT to the clinical model improved the AUC to 0.73. Optimal model that included gender, BMI, race (Black), MI, VAT/TAT, as well as interaction between gender and VAT/TAT and gender and MAT/MM demonstrated the highest AUC of 0.83. CONCLUSION: MAT/MM and VAT/TAT provides important prognostic information in predicting patients with COVID-19 who are likely to require hospitalization.

Novel Score for Stratifying Risk of Critical Care Needs in Patients With Intracerebral Hemorrhage.

OBJECTIVE: To develop a risk prediction score identifying patients with intracerebral hemorrhage (ICH) at low risk for critical care. METHODS: We retrospectively analyzed data of 451 patients with ICH between 2010 and 2018. The sample was randomly divided into a development and a validation cohort. Logistic regression was used to develop a risk score by weighting independent predictors of intensive care unit (ICU) needs according to strength of association. The risk score was tested in the validation cohort and externally validated in a dataset from another institution. RESULTS: The rate of ICU interventions was 80.3%. Systolic blood pressure (SBP), Glasgow Coma Scale (GCS) score, intraventricular hemorrhage (IVH), and ICH volume were independent predictors of critical care, resulting in the following point assignments for the Intensive Care Triaging in Spontaneous Intracerebral Hemorrhage (INTRINSIC) score: SBP 160 to 190 mm Hg (1 point), SBP >190 mm Hg (3 points); GCS 8 to 13 (1 point), GCS <8 (3 points); ICH volume 16 to 40 cm3 (1 point), ICH volume >40 cm3 (2 points); and presence of IVH (1 point), with values ranging between 0 and 9. Among patients with a score of 0 and no ICU needs during their emergency department stay, 93.6% remained without critical care needs. In an external validation cohort of patients with ICH, the INTRINSIC score achieved an area under the receiver operating characteristic curve of 0.823 (95% confidence interval 0.782-0.863). A score <2 predicted the absence of critical care needs with 48.5% sensitivity and 88.5% specificity, and a score <3 predicted the absence of critical care needs with 61.7% sensitivity and 83.0% specificity. CONCLUSION: The INTRINSIC score identifies patients with ICH who are at low risk for critical care interventions. CLASSIFICATION OF EVIDENCE: This study provides Class II evidence that the INTRINSIC score identifies patients with ICH at low risk for critical care interventions.

Prevalence of SARS-CoV-2 antibodies in pediatric healthcare workers.

OBJECTIVES: To determine SARS-CoV-2-antibody prevalence in pediatric healthcare workers (pHCWs). DESIGN: Baseline prevalence of anti-SARS-CoV-2-IgG was assessed in a prospective cohort study from a large pediatric healthcare facility. Prior SARS-CoV-2 testing history, potential risk factors and anxiety level about COVID-19 were determined. Prevalence difference between emergency department (ED)-based and non-ED-pHCWs was modeled controlling for those covariates. Chi-square test-for-trend was used to examine prevalence by month of enrollment. RESULTS: Most of 642 pHCWs enrolled were 31-40years, female and had no comorbidities. Half had children in their home, 49% had traveled, 42% reported an illness since January, 31% had a known COVID-19 exposure, and 8% had SARS-CoV-2 PCR testing. High COVID-19 pandemic anxiety was reported by 71%. Anti-SARS-CoV-2-IgG prevalence was 4.1%; 8.4% among ED versus 2.0% among non-ED pHCWs (p < 0.001). ED-work location and known COVID-19 exposure were independent risk factors. 31% of antibody-positive pHCWs reported no symptoms. Prevalence significantly (p < 0.001) increased from 3.0% in April-June to 12.7% in July-August. CONCLUSIONS: Anti-SARS-CoV-2-IgG prevalence was low in pHCWs but increased rapidly over time. Both working in the ED and exposure to a COVID-19-positive contact were associated with antibody-seropositivity. Ongoing universal PPE utilization is essential. These data may guide vaccination policies to protect front-line workers.

Missed Opportunities for Hepatitis A Vaccination Among MSM Initiating PrEP.

The incidence of Hepatitis A virus (HAV) among the general population in the United States has decreased by over 95% since the introduction of HAV vaccination in 1995. However, 10% of all new HAV infections occur among men who have sex with men (MSM). However routine HAV is not part of standard of care for provision of PrEP services. Retrospective cohort analysis of MSM assessed for HIV prevention services between 1/1/2016 and 6/30/2017 to evaluate the rates of screening for anti-HAV seroprevalence and subsequent vaccination. HAV IgG was drawn on 96% (96/100) of the patients with 58% (56/96) of patients demonstrating serologic immunity. Of the 40 patients without evidence of immunity, 77% (29/40) returned for a subsequent visit, 48% (14/29) were provided HAV vaccination, and 29% (4/14) received at least two doses. Only 35% (14/40) of patients without documented immunity received HAV vaccination. Visits for PrEP initiation and monitoring in MSM patients are potential opportunities for ensuring HAV vaccination among this high-risk patient population. Public health agencies could optimize HAV vaccination of the high risk MSM by incorporating HAV screening into national PrEP guidelines.
