Cardiopulmonary exercise testing on adaptive equipment in children and adults with Friedreich ataxia

INTRODUCTION/AIMS

Traditional exercise is often difficult for individuals with Friedreich ataxia (FRDA), and evidence is limited regarding how to measure exercise performance in this population. We evaluated the feasibility, reliability, and natural history of adaptive cardiopulmonary exercise test (CPET) performance in children and adults with FRDA.

METHODS

Participants underwent CPET on either an arm cycle ergometer (ACE) or recumbent leg cycle ergometer (RLCE) at up to four visits (baseline, 2 weeks, 4 weeks, and 1 year). Maximum work, oxygen consumption (peak VO2), oxygen (O2) pulse, and anaerobic threshold (AT) were measured in those who reached maximal volition. Test-retest reliability was assessed with intraclass coefficients, and longitudinal change was assessed using regression analysis.

RESULTS

In our cohort (N = 23), median age was 18 years (interquartile range [IQR], 14-23), median age of FRDA onset was 8 years (IQR 6-13), median Friedreich Ataxia Rating Scale score was 58 (IQR 54-62), and GAA repeat length on the shorter FXN allele (GAA1) was 766 (IQR, 650-900). Twenty-one (91%) completed a maximal CPET (n = 8, ACE and n = 13, RLCE). Age, sex, and GAA1 repeat length were each associated with peak VO2. Preliminary estimates demonstrated reasonable agreement between visits 2 and 3 for peak work by both ACE and RLCE, and for peak VO2, O2 pulse, and AT by RLCE. We did not detect significant performance changes over 1 year.

DISCUSSION

Adaptive CPET is feasible in FRDA, a relevant clinical trial outcome for interventions that impact exercise performance and will increase access to participation as well as generalizability of findings.

COVID-19 vaccine perspectives and uptake among university students three years into the pandemic

BACKGROUND

University students have been uniquely impacted by the COVID-19 pandemic for the past three years (2020-2023). Understanding their COVID-19 perspectives, beliefs, and vaccine uptake may help to improve future vaccine initiatives and education.

METHODS

A cross sectional, confidential, online survey was conducted at four universities in Pennsylvania in spring 2023 to assess undergraduate, graduate, and professional students' perspectives regarding their knowledge of COVID-19 vaccines, importance of COVID-19 vaccines and mandates, number of doses of COVID-19 vaccine received including the recent BA.4/BA.5 bivalent booster, where they were vaccinated, receipt of influenza vaccine, and sources of information used to make decisions about COVID-19 vaccine.

RESULTS

Vaccination for COVID-19 was considered important by 75 % of 2223 students surveyed; 68 % agreed with mandating COVID-19 vaccine. Over 89 % were fully COVID-19 vaccinated (≥2 doses), 65 % were up-to-date (≥3 doses), but only 35 % had received the BA.4/BA.5 booster. Students who considered COVID-19 vaccine important were generally older, female, and non-business majors. Higher rates of up-to-date COVID-19 vaccination were found in those who received influenza vaccine in 2022-2023, females, Asians, doctoral or professional students, those attending larger universities, non-US residents, and those interested in learning more about COVID-19 vaccines. Most trusted sources of information on COVID-19 vaccines were the Centers for Disease Control and Prevention, healthcare providers, and parents; the least trusted sources were social media, television, and the internet.

CONCLUSIONS

The majority of university students agreed that COVID-19 vaccination is important and supported COVID-19 mandates. While the rate of fully vaccinated and up-to-date students was similar to the US adult population, the latter rate needs improvement. Receipt of the BA.4/BA.5 booster was particularly low. Further education is needed to improve vaccine knowledge, especially as we move to periodic boosters. Business majors, males, and younger students may benefit from increased on-campus vaccine education initiatives.

Clinical features associated with pulmonary exacerbation diagnosis in infants and young children with cystic fibrosis

RATIONALE

Diagnosing cystic fibrosis (CF) pulmonary exacerbations (PEx) in very young people with CF <3 years (VY-PwCF) is challenging because of the frequency of respiratory viral infections in this age group, and there are limited data on the clinical features associated with the diagnosis of PEx in this age group. The goal of this study was to identify clinical features associated with the diagnosis of PEx in VY-PwCF.

METHODS

We reviewed the medical records of VY-PwCF followed at the Children's Hospital of Philadelphia born between 2013 and 2019. We collected data from all encounters with respiratory symptoms. PEx was defined by treatment with oral or intravenous antibiotics. Clinical features of PEx and non-PEx encounters were compared using descriptive statistics, and odds ratios of PEx diagnosis were calculated.

RESULTS

A total of 78 patients were included in the analysis. The mean (SD) number of PEx per patient was 6.17 (5.88). The presence of a wet or nighttime cough and symptoms >3 days in duration were significantly associated with PEx diagnosis (p < .001). In contrast, symptoms such as sore throat or rhinorrhea were not associated with a higher likelihood of PEx.

CONCLUSIONS

The presence of a wet or night-time cough and longer symptom duration are common features of PEx in VY-PwCF, whereas symptoms suggestive of upper respiratory viral infection are not. Our results will be helpful in counseling families of VY-PwCF in the signs and symptoms of PEx and in planning future research in PEx in this age group.

Acquisition and Loss of Developmental Milestones and Time to Disease-Related Outcomes in Cerebral Alexander Disease

Objective: To determine the ages at acquisition of developmental milestones, loss of motor function, and clinical symptoms in Alexander disease. Methods: Patients with confirmed cerebral Alexander disease were included. Data abstraction of developmental and disease-specific milestones was performed from medical records, physical exams, and questionnaires. Mixed effects logistic regression was used to determine if key clinical features were associated with milestone achievement, controlling for patient age. Results: 51 patients with cerebral/infantile Alexander disease were evaluated at a mean age of 10.96 years (range 2.29-31.08 years). Developmental milestones in Alexander disease were often achieved but delayed. Ambulation was achieved in 44 subjects (86%); 34 (67%) subjects walked independently (mean age 1.9 years, range 0.91-3.25 years) and an additional 10 (20%) subjects walked with assistance (mean age 3.9 years, range 1.8-8 years) but did not progress to independent ambulation. Developmental delay was the earliest and most prevalent symptom (N = 48 [94%], mean age 0.58 years), compared to an initial seizure (N = 41 [80%], mean age 2.80 years), and macrocephaly (N = 28 [55%], mean age 4.04 years), P < .0001 between these ages of onset. Loss of independent ambulation occurred in 11 of the 34 (32%) children who had acquired ambulation (range 3.41-15.10 years). Presence of seizures or macrocephaly did not predict the achievement or loss of ambulation. Conclusions: The clinical triad of developmental delay, seizures, and macrocephaly are not universally present in cerebral Alexander disease. Clinicians should have a high index of suspicion for Alexander disease in patients with mild delays and a first seizure.

Lower Completion of Depression Screening and Higher Positivity Among Autistic Adolescents Across a Large Pediatric Primary Care Network

OBJECTIVE

To examine rates of depression screening and positivity among autistic adolescents where electronic depression screening is administered universally; to compare rates between autistic and nonautistic youth; and to explore sociodemographic and clinical factors associated with screening completion and results.

METHODS

We conducted a retrospective cohort study comparing 12-17-year-old autistic and nonautistic adolescents presenting for well-child care in a large pediatric primary care network between November 2017 and January 2019 (N = 60,181). Sociodemographic and clinical data, including PHQ-9-M completion status and results, were extracted digitally from the electronic health record and compared between autistic and nonautistic youth. Logistic regression explored the relationship between sociodemographic and clinical factors and screen completion and results, stratified by autism diagnosis.

RESULTS

Autistic adolescents were significantly less likely to have a completed depression screen compared to nonautistic adolescents [67.0% vs 78.9%, odds ratio (OR) = 0.54, P < .01]. Among those with a completed screen, a higher percentage of autistic youths screened positive for depression (39.1% vs 22.8%; OR = 2.18, P < .01,) and suicidal ideation/behavior (13.4% vs 6.8%; OR = 2.13, P < .01). Factors associated with screening completion and positivity differed between autistic and nonautistic groups.

CONCLUSIONS

Autistic adolescents were less likely to have a completed depression screen when presenting for well-child care. However, when screened, they were more likely to endorse depression and suicide risk. This suggests disparities in depression screening and risk among autistic youth compared to nonautistic youth. Additional research should evaluate the source of these disparities, explore barriers to screening, and examine longitudinal outcomes of positive results among this population.

A multicenter study analyzing the impact of pre-existing comorbidities on laryngotracheal reconstruction (LTR) outcomes

INTRODUCTION

Comorbidities such as chronic lung disease and gastroesophageal reflux (GERD), prematurity, and numerous other conditions may impact the success of LTR. Single-center studies are limited in terms of patient numbers and may be underpowered.

OBJECTIVES

To analyze the impact of specific comorbidities on the operation-specific and overall surgical success of LTR in a large multicenter cohort and validate a predictive model for surgical success.

METHODS

A large retrospective multicenter 10-year review was undertaken to validate the data of a previous single-center study (Wertz et al. Laryngoscope 2020) which identified specific predictive comorbidities which impacted LTR outcomes. A Monte Carlo simulation based on the previous data set suggested that 300-400 cases would be needed to optimize the statistical power of a Bayesian model developed from the single-center data to predict surgical success. An IRB-approved data-sharing agreement was executed for 4 large U.S.

CENTERS

A virtual REDCap® data entry form inquired about patient characteristics that best predicted surgical success in the single-center model. These included demographics, surgical approaches, cardiac, airway, genetic, endocrine, musculoskeletal, gastrointestinal, and pulmonary comorbidities; details of the surgical procedures, and results of esophagogastroduodenoscopy (EGD), esophageal pH/impedance and flexible bronchoscopy with bronchioalveolar lavage (BAL) were included. Surgical success defined as successful decannulation or resolution of airway symptoms was recorded as single surgery success and overall success following open surgical revision surgery. Multivariate Bayesian analysis, logistical regression, and Kaplan-Meier analysis were performed.

RESULTS

542 patients were identified, including 165 from the single-center study and an additional 377 patients from the multicenter group. The median age was 36 months at the time of the most recent surgery. 70.9% of the LTRs were double-staged procedures. The overall success rate was 86.4% and operation-specific success rate was 69.2%. The specific comorbidities and aerodigestive test results that impacted success based on univariate analysis included staging, bronchiectasis, pulmonary hypertension, GERD, ASD, PDA, grade of stenosis, advanced levels of stenosis, Trisomy 21, MRSA, prior open surgery at another hospital, and gross appearance on EGD. Bayesian model averaging with backward selection was used to validate and refine a predictive model for surgical success with favorable receiver operating curve characteristics - AUC values of 0.827 for single surgery success and 0.797 for overall success.

DISCUSSION

With over 500 patients reviewed, this was the largest multicenter study of LTR to date, which elucidated the impact of comorbidities on success with LTR and was able to improve upon the predictive modeling based on single-center data. Patient factors are most critical in the outcome of LTR. Stage and levels of stenosis, as well as pulmonary and GI conditions most strongly impact the likelihood of success. Future prospective case-control studies will be performed to further optimize the current model for outcome prediction and patient management.

Patient and Parent Characteristics Related to Quality of Life and Self-Esteem in Healthy Youth Undergoing Provocative Growth Hormone Testing

OBJECTIVE

To examine how height and youth as well as parenting characteristics associate with quality of life (QoL) and self-esteem among healthy youth undergoing growth evaluation with growth hormone (GH) testing.

STUDY DESIGN

Healthy youth, aged 8-14 years, undergoing provocative GH testing, and a parent completed surveys at or around the time of testing. Surveys collected demographic data; youth and parent reports of youth health-related QoL; youth reports of self-esteem, coping skills, social support, and parental autonomy support; and parent reports of perceived environmental threats and achievement goals for their child. Clinical data were extracted from electronic health records. Univariate models and multivariable linear regressions were used to identify factors associated with QoL and self-esteem.

RESULTS

Sixty youth (mean height z score -2.18 ± 0.61) and their parents participated. On multivariable modeling, youth perceptions of their physical QoL associated with higher grade in school, greater friend and classmate support, and older parent age; youth psychosocial QoL with greater friend and classmate support, and with less disengaged coping; and youth height-related QoL and parental perceptions of youth psychosocial QoL with greater classmate support. Youth self-esteem associated with greater classmate support and taller mid-parental height. Youth height was not associated with QoL or self-esteem outcomes in multivariable regression.

CONCLUSIONS

Perceived social support and coping skills, rather than height, were related to QoL and self-esteem in healthy short youth and may serve as an important potential area for clinical intervention.

Short-Course Therapy for Urinary Tract Infections in Children: The SCOUT Randomized Clinical Trial

Importance

There is a paucity of pediatric-specific comparative data to guide duration of therapy recommendations in children with urinary tract infection (UTI).

Objective

To compare the efficacy of standard-course and short-course therapy for children with UTI.

Design, Setting, Participants

The Short Course Therapy for Urinary Tract Infections (SCOUT) randomized clinical noninferiority trial took place at outpatient clinics and emergency departments at 2 children's hospitals from May 2012, through, August 2019. Data were analyzed from January 2020, through, February 2023. Participants included children aged 2 months to 10 years with UTI exhibiting clinical improvement after 5 days of antimicrobials.

Intervention

Another 5 days of antimicrobials (standard-course therapy) or 5 days of placebo (short-course therapy).

Main Outcome Measures

The primary outcome, treatment failure, was defined as symptomatic UTI at or before the first follow-up visit (day 11 to 14). Secondary outcomes included UTI after the first follow-up visit, asymptomatic bacteriuria, positive urine culture, and gastrointestinal colonization with resistant organisms.

Results

Analysis for the primary outcome included 664 randomized children (639 female [96%]; median age, 4 years). Among children evaluable for the primary outcome, 2 of 328 assigned to standard-course (0.6%) and 14 of 336 assigned to short-course (4.2%) had a treatment failure (absolute difference of 3.6% with upper bound 95% CI of 5.5.%). Children receiving short-course therapy were more likely to have asymptomatic bacteriuria or a positive urine culture at or by the first follow-up visit. There were no differences between groups in rates of UTI after the first follow-up visit, incidence of adverse events, or incidence of gastrointestinal colonization with resistant organisms.

Conclusions and Relevance

In this randomized clinical trial, children assigned to standard-course therapy had lower rates of treatment failure than children assigned to short-course therapy. However, the low failure rate of short-course therapy suggests that it could be considered as a reasonable option for children exhibiting clinical improvement after 5 days of antimicrobial treatment.

Long-Term Kidney and Cardiovascular Complications in Pediatric Cancer Survivors

OBJECTIVE

The objective of this study was to describe the burden of adverse kidney and hypertension outcomes in patients evaluated by pediatric nephrology in a multidisciplinary survivorship clinic.

STUDY DESIGN

Retrospective chart review of all patients followed up by nephrology in our multidisciplinary survivorship clinic from August 2013 to June 2021. Data included clinic blood pressure, longitudinal ambulatory blood pressure monitoring (ABPM), echocardiography, serum creatinine, and first-morning urine protein/creatinine ratios. For patients with multiple ABPMs, results of initial and most recent ABPMs were compared.

RESULTS

Of 422 patients followed in the multidisciplinary cancer survivorship clinic, 130 were seen by nephrology. The median time after therapy completion to first nephrology visit was 8 years. The most common diagnoses were leukemia/myelodysplastic syndrome (27%), neuroblastoma (24%), and Wilms tumor (15%). At the last follow-up, 68% had impaired kidney function, 38% had a clinical diagnosis of hypertension, and 12% had proteinuria. There were 91 ABPMs performed in 55 (42%) patients. Patients with multiple ABPMs (n = 21) had statistically significant reductions in overall median blood pressure loads: systolic initial load 37% vs most recent 10% (P = .005) and diastolic load 36% vs 14% (P = .017). Patients with impaired kidney function were more likely to have received ifosfamide. Patients with hypertension were more likely to have received total body irradiation or allogeneic stem cell transplant.

CONCLUSIONS

History of leukemia/myelodysplastic syndrome, neuroblastoma, and Wilms tumor was frequent among survivors seen by nephrology. There was significant improvement in cardiovascular measures with increased recognition of hypertension and subsequent treatment.

Assessing pain catastrophizing and functional disability in pediatric epidermolysis bullosa patients

BACKGROUND/OBJECTIVES

The primary objective was to assess pain catastrophizing and functional disability in pediatric patients with epidermolysis bullosa (EB) and their parents/guardians. Secondary objectives included examining relationships between pain catastrophizing, functional disability, and correlations with other factors (e.g., age, disease severity, and percent of body surface area (BSA) involved).

METHODS

Patients with EB ages 8-16 and their parents/guardians who were English or Spanish speaking completed a one-time online survey. Parent measures included: demographics questionnaire, Pain Catastrophizing Scale-Parent (PCS), and Parent Functional Disability Inventory (FDI). Child measures included: PCS child and child FDI. Higher scores on both scales indicate higher levels of catastrophizing and functional disability.

RESULTS

Of 31 children, the mean age was 11.47 years and the majority (70.97%) had dystrophic EB. Mean scores were: 35.84 = PCS parent; 34.58 = PCS child; 30.87 = parent FDI; 29.77 = child FDI. Total scores for PCS parent, parent FDI, and child FDI increased significantly with disease severity and percentage of involved BSA (p < .01 for all). Total scores for PCS child increased significantly with percent of EB skin involvement (p = .04) but not disease severity. Older children reported more functional disability than their parents and younger children (p = .02).

CONCLUSIONS

Our results demonstrate significant positive correlations between negative thoughts related to pain and the experience of functional difficulties in patients with EB and their caregivers. Psychological, psychiatric, and/or behavioral interventions to help managing chronic pain may be effective for patients with EB.

RF26 | PMON327 Patient and Parent Characteristics Related to Quality of Life and Self-esteem in Healthy Youth Undergoing Provocative GH Testing

Background

Families often seek medical care for a child's short stature due to concerns about how short stature affects psychosocial function in childhood and projected into adulthood. However, height is a poor predictor of psychosocial adjustment, and there is a critical gap in our understanding of how patient and parent characteristics alter the potential impact of being short.

Hypothesis

We hypothesized that among healthy youth undergoing medical evaluation for short stature, youth quality of life (QoL) and self-esteem would be associated with youth and parental characteristics rather than height.

Methods

Healthy youth aged 8-14 years who underwent provocative GH testing in our Growth Center and a parent participant each completed surveys at or around the time of testing. Surveys collected demographic data; youth and parent report of youth health-related QoL (PedsQL and Quality of Life in Short Stature Youth [QoLISSY]); youth reports of self-esteem (Self-Perception Profile for Children [SPP]), coping skills (Coping Strategies Inventory), and social support (Social Support Scale for Children); and parent reports of perceived environmental threats (World Out There), goals for their child (Achievement Goals), and autonomy support (Parents As Social Context Questionnaire). Clinical data were extracted from the patients’ electronic health records. Continuous variables were summarized as mean ± SD. Univariate models with Holm-Bonferroni correction of significance level 0.05 assessed the marginal effect of each factor on QoL and self-esteem outcomes. Multivariable linear regression models with stepwise selection approaches were used to identify significant predictors of QoL and self-esteem.

Results

Participants included 60 youth (15 female/45 male; age 11.77 ± 1.93 years; 50% prepubertal, 37% Tanner 2, 13% Tanner 3; height Z-score -2.18 ± 0.61) and their parents (55 female/5 male; age 45.65 ± 7.25 years). In multivariable regression, the youth PedsQL physical domain was associated positively with grade in school and perceived friend support. The youth PedsQL psychosocial domain was associated positively with perceived support from classmates and friends, but negatively with disengaged coping. The youth QoLISSY total score was associated positively with perceived support from classmates. Youth's global self-esteem (SPP) was associated positively with perceived classmate support and mid-parental height Z-score. Parent report of youth psychosocial QoL (PedsQL) was associated positively with perceived classmate support. None of the other analogous parent assessment outcomes were associated with the QoL or self-esteem outcomes. Neither youth height nor height Z-score was associated with any of the QoL or self-esteem outcomes.

Conclusions

Perceived social support and coping skills were associated with QoL and self-esteem in healthy short youth, whereas youth height was not, and constitute an important potential area of clinical intervention.

Coronavirus disease 2019 (COVID-19) vaccine hesitancy among physicians, physician assistants, nurse practitioners, and nurses in two academic hospitals in Philadelphia

OBJECTIVE

To evaluate coronavirus disease 2019 (COVID-19) vaccine hesitancy among healthcare personnel (HCP) with significant clinical exposure to COVID-19 at 2 large, academic hospitals in Philadelphia, Pennsylvania.

DESIGN, SETTING, AND PARTICIPANTS

HCP were surveyed in November-December 2020 about their intention to receive the COVID-19 vaccine.

METHODS

The survey measured the intent among HCP to receive a COVID-19 vaccine, timing of vaccination, and reasons for or against vaccination. Among patient-facing HCP, multivariate regression evaluated the associations between healthcare positions (medical doctor, nurse practitioner or physician assistant, and registered nurse) and vaccine hesitancy (intending to decline, delay, or were unsure about vaccination), adjusting for demographic characteristics, reasons why or why not to receive the vaccine, and prior receipt of routine vaccines.

RESULTS

Among 5,929 HCP (2,253 medical doctors [MDs] and doctors of osteopathy [DOs], 582 nurse practitioners [NPs], 158 physician assistants [PAs], and 2,936 nurses), a higher proportion of nurses (47.3%) were COVID-vaccine hesitant compared with 30.0% of PAs and NPs and 13.1% of MDs and DOs. The most common reasons for vaccine hesitancy included concerns about side effects, the newness of the vaccines, and lack of vaccine knowledge. Regardless of position, Black HCP were more hesitant than White HCP (odds ratio [OR], ∼5) and females were more hesitant than males (OR, ∼2).

CONCLUSIONS

Although most clinical HCP intended to receive a COVID-19 vaccine, intention varied by healthcare position. Consistent with other studies, hesitancy was also significantly associated with race or ethnicity across all positions. These results highlight the importance of understanding and effectively addressing reasons for hesitancy, especially among frontline HCP who are at increased risk of COVID exposure and play a critical role in recommending vaccines to patients.

Urinary HER2, TWEAK and VCAM-1 levels are associated with new-onset proteinuria in paediatric lupus nephritis

Objective

Lupus nephritis is a key driver of morbidity and mortality in SLE. Detecting active nephritis on a background of pre-existing renal damage is difficult, leading to potential undertreatment and accumulating injury. An unmet need is a biomarker that distinguishes active lupus nephritis, particularly important in paediatrics where minimising invasive procedures is desirable.

Methods

This was a multicentre, prospective study of 113 paediatric patients with biopsy-proven lupus nephritis. Clinical data and urine were obtained every 3–4 months and patients averaged 2 years on study with seven time points. Urine was analysed for human epidermal growth factor receptor 2 (HER2), tumour necrosis factor-like weak inducer of apoptosis and vascular cell adhesion molecule-1 (VCAM-1) by ELISA. We defined active disease as either a rise in serum creatinine ≥0.3 mg/dL from baseline or a rise in renal Systemic Lupus Erythematosus Disease Activity Index score from the previous visit. These markers were also studied in patients with acute kidney injury, juvenile idiopathic arthritis (JIA), amplified pain syndrome and healthy controls.

Results

The rate of active disease was 56% over an average of 2 years of follow-up. HER2 and VCAM-1 were significantly elevated at time points with active disease defined by increased serum creatinine compared with time points with inactive disease or patients who never flared. All three biomarkers were associated with new-onset proteinuria and VCAM-1 was elevated at time points preceding new-onset proteinuria. These biomarkers were not increased in acute kidney injury or JIA.

Conclusion

All three biomarkers were associated with new onset proteinuria and increased VCAM-1 may predict impending proteinuria. These biomarkers provide potential non-invasive measures for monitoring that may be more sensitive to impending flare than conventional measures.

An Integrated Analysis of Clinical, Genomic, and Imaging Features Reveals Predictors of Neurocognitive Outcomes in a Longitudinal Cohort of Pediatric Cancer Survivors, Enriched with CNS Tumors (Rad ART Pro)

Background

Neurocognitive deficits in pediatric cancer survivors occur frequently; however, individual outcomes are unpredictable. We investigate clinical, genetic, and imaging predictors of neurocognition in pediatric cancer survivors, with a focus on survivors of central nervous system (CNS) tumors exposed to radiation.

Methods

One hundred eighteen patients with benign or malignant cancers (median diagnosis age: 7; 32% embryonal CNS tumors) were selected from an existing multi-institutional cohort (RadART Pro) if they had: 1) neurocognitive evaluation; 2) available DNA; 3) standard imaging. Utilizing RadART Pro, we collected clinical history, genomic sequencing, CNS imaging, and neurocognitive outcomes. We performed single nucleotide polymorphism (SNP) genotyping for candidate genes associated with neurocognition: COMT, BDNF, KIBRA, APOE, KLOTHO. Longitudinal neurocognitive testing were performed using validated computer-based CogState batteries. The imaging cohort was made of patients with available iron-sensitive (n = 28) and/or T2 FLAIR (n = 41) sequences. Cerebral microbleeds (CMB) were identified using a semi-automated algorithm. Volume of T2 FLAIR white matter lesions (WML) was measured using an automated method based on a convolutional neural network. Summary statistics were performed for patient characteristics, neurocognitive assessments, and imaging. Linear mixed effects and hierarchical models assessed patient characteristics and SNP relationship with neurocognition over time. Nested case-control analysis was performed to compare candidate gene carriers to non-carriers.

Results

CMB presence at baseline correlated with worse performance in 3 of 7 domains, including executive function. Higher baseline WML volumes correlated with worse performance in executive function and verbal learning. No candidate gene reliably predicted neurocognitive outcomes; however, APOE ϵ4 carriers trended toward worse neurocognitive function over time compared to other candidate genes and carried the highest odds of low neurocognitive performance across all domains (odds ratio 2.85, P=0.002). Hydrocephalus and seizures at diagnosis were the clinical characteristics most frequently associated with worse performance in neurocognitive domains (5 of 7 domains). Overall, executive function and verbal learning were the most frequently negatively impacted neurocognitive domains.

Conclusion

Presence of CMB, APOE ϵ4 carrier status, hydrocephalus, and seizures correlate with worse neurocognitive outcomes in pediatric cancer survivors, enriched with CNS tumors exposed to radiation. Ongoing research is underway to verify trends in larger cohorts.

RARE-17. Multi-institutional craniopharyngioma cohort highlights need for more comprehensive data collection on comorbidities and quality of life

BACKGROUND: Pediatric craniopharyngioma is associated with long-term survival, but tumor- and therapy-related complications often negatively impact quality of life (QoL). Standard treatments include resection and radiation, but institutional practices vary and recurrence rates remain high. In this review, we utilized a cohort from the Children’s Brain Tumor Network (CBTN) to evaluate outcomes for craniopharyngioma. METHODS: CBTN provides clinical and genomic data for pediatric patients diagnosed with primary central nervous system tumors across 25+ institutions. We collected data for 124 patients, ages 0-21, diagnosed with craniopharyngioma between 2012-2020. Variables collected included treatment, recurrence/progression, and comorbidities. RESULTS: Excluding patients without confirmed pathologic diagnosis (n=10) or follow-up data (n=39), 75 patients remained. For initial treatment, most (n=46, 61%) received surgery alone (9 partial, 33 near-total resection). Twenty-six (35%) underwent both surgery and radiation, with 9 receiving both therapies upfront and 17 receiving radiation at progression/recurrence. Four (5%) patients received chemotherapy. Over half of the cohort (n=39, 52%) had at least one progression/recurrence, and four died (5%). Significantly higher rates of progression/recurrence (84% vs. 32%, p=4.0e-5) were identified in patients that had surgery and radiation, compared to surgery alone. Time to recurrence, progression, or death was shorter for the surgery and radiation group (HR=4.1, p<1.0e-4), and for those that underwent partial versus near-total resection (HR=2.7, p=0.1.2e-2). Comorbidities were likely underreported, based on low rates of visual (32%), neuroendocrine (27%), and neurologic (28%) deficits at diagnosis, and 29 patients (39%) with unspecified medical history. CONCLUSIONS: CBTN provides a robust repository of information on treatment and survival of craniopharyngioma patients. However, we found a paucity of data on associated comorbidities and QoL outcomes. We advocate that future datasets and clinical trials routinely collect functional outcomes alongside therapy and survival data, particularly in craniopharyngioma where long-term survival is balanced with future QoL.

Racial/Ethnic Differences in COVID-19 Vaccine Hesitancy Among Health Care Workers in 2 Large Academic Hospitals

IMPORTANCE

Significant differences in hesitancy to receive COVID-19 vaccination by race/ethnicity have been observed in several settings. Racial/ethnic differences in COVID-19 vaccine hesitancy among health care workers (HCWs), who face occupational and community exposure to COVID-19, have not been well described.

OBJECTIVE

To assess hesitancy to COVID-19 vaccination among HCWs across different racial/ethnic groups and assess factors associated with vaccine hesitancy.

DESIGN, SETTING, AND PARTICIPANTS

This survey study was conducted among HCWs from 2 large academic hospitals (ie, a children's hospital and an adult hospital) over a 3-week period in November and December 2020. Eligible participants were HCWs with and without direct patient contact. A 3-step hierarchical multivariable logistic regression was used to evaluate associations between race/ethnicity and vaccine hesitancy controlling for demographic characteristics, employment characteristics, COVID-19 exposure risk, and being up to date with routine vaccinations. Data were analyzed from February through March 2021.

MAIN OUTCOMES AND MEASURES

Vaccine hesitancy, defined as not planning on, being unsure about, or planning to delay vaccination, served as the outcome.

RESULTS

Among 34 865 HCWs eligible for this study, 12 034 individuals (34.5%) completed the survey and 10 871 individuals (32.2%) completed the survey and reported their race/ethnicity. Among 10 866 of these HCWs with data on sex, 8362 individuals (76.9%) were women, and among 10 833 HCWs with age data, 5923 individuals (54.5%) were younger than age 40 years. (Percentages for demographic and clinical characteristics are among the number of respondents for each type of question.) There were 8388 White individuals (77.2%), 882 Black individuals (8.1%), 845 Asian individuals (7.8%), and 449 individuals with other or mixed race/ethnicity (4.1%), and there were 307 Hispanic or Latino individuals (2.8%). Vaccine hesitancy was highest among Black HCWs (732 individuals [83.0%]) and Hispanic or Latino HCWs (195 individuals [63.5%]) (P < .001). Among 5440 HCWs with vaccine hesitancy, reasons given for hesitancy included concerns about side effects (4737 individuals [87.1%]), newness of the vaccine (4306 individuals [79.2%]), and lack of vaccine knowledge (4091 individuals [75.2%]). The adjusted odds ratio (aOR) for vaccine hesitancy was 4.98 (95% CI, 4.11-6.03) among Black HCWs, 2.10 (95% CI, 1.63-2.70) among Hispanic or Latino HCWs, 1.48 (95% CI, 1.21-1.82) among HCWs with other or mixed race/ethnicity, and 1.47 (95% CI, 1.26-1.71) among Asian HCWs compared with White HCWs (P < .001). The aOR was decreased among Black HCWs when adjusting for employment characteristics and COVID-19 exposure risk (aOR, 4.87; 95% CI, 3.96-6.00; P < .001) and being up to date with prior vaccines (aOR, 4.48; 95% CI, 3.62-5.53; P < .001) but not among HCWs with other racial/ethnic backgrounds.

CONCLUSIONS AND RELEVANCE

This study found that vaccine hesitancy before the authorization of the COVID-19 vaccine was increased among Black, Hispanic or Latino, and Asian HCWs compared with White HCWs. These findings suggest that interventions focused on addressing vaccine hesitancy among HCWs are needed.

Perspectives on the receipt of a COVID-19 vaccine: A survey of employees in two large hospitals in Philadelphia

Background

Health care personnel have been identified by the ACIP as a priority group for COVID-19 vaccination. We conducted a survey in November-December 2020 at two large, academic hospitals in Philadelphia to evaluate the intention of hospital employees to be vaccinated.

Methods

The survey was sent electronically to all employees (clinical and nonclinical staff) at a children’s hospital and an adult hospital. The survey was voluntary and confidential. Questions focused on plans to receive a COVID-19 vaccine when available, reasons why employees would/would not get vaccinated, when employees planned to be vaccinated, vaccine safety and efficacy features that would be acceptable, and past history of receipt of other vaccines by the employee and family. Responses were analyzed using univariate and multiple logistic regression methods.

Results

A total of 12,034 hospital employees completed the survey (a 34.5% response rate). Overall, 63.7% of employees reported that they planned to receive a COVID-19 vaccine, 26.3% were unsure, and 10.0% did not plan to be vaccinated. Over 80% of those unsure or unwilling to be vaccinated expressed concerns about vaccine side effects and the vaccines’ newness. In multivariable logistic regression, persons planning to take a COVID-19 vaccine were more likely to be older, male, more educated, Asian or White, up-to-date on vaccinations, without direct patient contact, and tested for COVID-19 in the past. No significant difference in intention to be vaccinated was found between those with higher versus lower levels of exposure to COVID-19 patients or the number of previous exposures to patients with COVID-19.

Conclusions

While the majority of hospital employees are planning to receive a COVID-19 vaccine, many are unsure or not planning to do so. Further education of hospital employees about the safety, efficacy, and value of the currently available COVID-19 vaccines is critical to vaccine acceptance in this population.

The temporal relationship between juvenile idiopathic arthritis disease activity and uveitis activity

OBJECTIVE

To determine whether there is a temporal association between arthritis and uveitis activity among children with juvenile idiopathic arthritis-associated uveitis (JIA-U).

METHODS

Uveitis and arthritis data from JIA-U patients ≤21 years were collected from 7/2013-12/2019 at a tertiary care center. Arthritis activity was assessed at each rheumatology visit, and the primary outcome was the presence of active uveitis at ophthalmologic exams within 45 days of the rheumatology visit. Repeated measures logistic regression was used to evaluate the temporal association between any uveitis activity within 45 days of arthritis activity. Models were adjusted for demographic, disease, and treatment-related factors.

RESULTS

Ninety eight patients were included; 81 (82%) female, 67 (69%) anti-nuclear antibody positive, 59 (60%) oligoarticular and 13 (13%) enthesitis related arthritis (ERA) subtypes. There were 1229 rheumatology visits with a median of 13 visits per patient (interquartile range 7 - 18). Concordance between arthritis and uveitis activity was observed 73% (694/947) of the time. There was an independent temporal association between uveitis and arthritis activity, odds ratio (OR) 2.47 [95% confidence interval 1.72, 3.54; p<0.01], adjusted for demographic and disease characteristics. Use of combination biologic and non-biologic disease modifying anti-rheumatic drugs, female sex, HLA-B27 positivity, ERA and polyarticular (RF-) subtypes were associated with decreased odds of active uveitis at any time point.

CONCLUSION

In patients with JIA-U, there is a significant temporal association between arthritis and uveitis disease activity. These novel results suggest that an arthritis flare should prompt an expedited referral to the ophthalmologist.

Differences in length of stay and discharge destination among patients with substance use disorders: The effect of Substance Use Intervention Team (SUIT) consultation service

BACKGROUND

Addiction medicine consultation services (ACS) may improve outcomes of hospitalized patients with substance use disorders (SUD). Our aim was to examine the difference in length of stay and the hazard ratio for a routine hospital discharge between SUD patients receiving and not receiving ACS.

METHODS

Structured EHR data from 2018 of 1,900 adult patients with a SUD-related diagnostic code at an urban academic health center were examined among 35,541 total encounters. Cox proportional hazards regression models were fit using a cause-specific approach to examine differences in hospital outcome (i.e., routine discharge, leaving against medical advice, in-hospital death, or transfer to another level of care). Models were adjusted for age, sex, race, ethnicity, insurance status, and comorbidities.

RESULTS

Length of stay was shorter among encounters with a SUD that received a SUIT consultation versus those admissions that did not receive one (5.77 v. 6.54 days, p<0.01). In adjusted analyses, admissions that received a SUIT consultation had a higher hazard of a routine discharge [hazard ratio (95% confidence interval): 1.16 (1.03-1.30)] compared to those not receiving a SUIT consultation.

CONCLUSIONS

The SUIT consultation service was associated with a reduced length of stay and an increased hazard of a routine discharge. The SUIT model may serve as a benchmark and inform other health systems attempting to improve outcomes in SUD patient cohorts.

Collaborative Care for Depression of Adults and Adolescents: Measuring the Effectiveness of Screening and Treatment Uptake

OBJECTIVE

This study analyzed effectiveness of screening, referrals, and treatment uptake of a collaborative care for depression intervention across 10 primary care clinics in Chicago.

METHODS

Between November 2016 and December 2017, patients (N=25,369) were screened with the Patient Health Questionnaire-2 and the Patient Health Questionnaire-9 on the basis of an eligibility algorithm. Electronic health record data were analyzed for sample characteristics, screening rates, referrals, and treatment pathways. To identify disparities, a test of proportions was conducted between eligible and screened patients as well as referred and treated patients.

RESULTS

Screenings, referrals, and uptake occurred proportionately across subgroups except for patients ages 12-17. Adolescent age was associated with disproportionate Patient Health Questionnaire-9 screenings and with treatment disengagement.

CONCLUSIONS

The intervention shows promise in expanding access to care and reducing disparities. Greater access to psychotherapies and innovative treatment modalities, particularly for adolescents, may improve overall treatment uptake.

A joint marginal-conditional model for multivariate longitudinal data

Multivariate longitudinal data frequently arise in biomedical applications; however, their analyses are often performed one outcome at a time, or jointly using existing software in an ad hoc fashion. A main challenge in the proper analysis of such data is the fact that the different outcomes are measured on different unknown scales. Methodology for handling the scale problem has been previously proposed for cross-sectional data, and here we extend it to the longitudinal setting. We consider modeling the longitudinal data using random effects, while leaving the joint distribution of the multiple outcomes unspecified. We propose an estimating equation together with an expectation-maximization-type (expectation-substitution) algorithm. The consistency and the asymptotic distribution of the parameter estimates are established. The method is evaluated using extensive simulations and applied to a longitudinal nutrition data set from a large dietary intervention trial on breast cancer survivors, the Women's Healthy Eating and Living Study.
