Are asymptomatic carriers of OTC deficiency always asymptomatic? A multicentric retrospective study of risk using the UCDC longitudinal study database.

BACKGROUND: Ornithine transcarbamylase deficiency (OTCD) due to an X-linked OTC mutation, is responsible for moderate to severe hyperammonemia (HA) with substantial morbidity and mortality. About 80% of females with OTCD remain apparently "asymptomatic" with limited studies of their clinical characteristics and long-term health vulnerabilities. Multimodal neuroimaging studies and executive function testing have shown that asymptomatic females exhibit limitations when stressed to perform at higher cognitive load and had reduced activation of the prefrontal cortex. This retrospective study aims to improve understanding of factors that might predict development of defined complications and serious illness in apparent asymptomatic females. A proband and her daughter are presented to highlight the utility of multimodal neuroimaging studies and to underscore that asymptomatic females with OTCD are not always asymptomatic. METHODS: We review data from 302 heterozygote females with OTCD enrolled in the Urea Cycle Disorders Consortium (UCDC) longitudinal natural history database. We apply multiple neuroimaging modalities in the workup of a proband and her daughter. RESULTS: Among the females in the database, 143 were noted as symptomatic at baseline (Sym). We focused on females who were asymptomatic (Asx, n = 111) and those who were asymptomatic initially upon enrollment in study but who later became symptomatic sometime during follow-up (Asx/Sym, n = 22). The majority of Asx (86%) and Asx/Sym (75%) subjects did not restrict protein at baseline, and ~38% of Asx and 33% of Asx/Sym subjects suffered from mild to severe neuropsychiatric conditions such as mood disorder and sleep problems. The risk of mild to severe HA sometime later in life for the Asx and Asx/Sym subjects as a combined group was ~4% (5/133), with ammonia ranging from 77 to 470 µM and at least half (2/4) of subjects requiring hospital admission and nitrogen scavenger therapy. For this combined group, the median age of first HA crisis was 50 years, whereas the median age of first symptom which included neuropsychiatric and/or behavioral symptoms was 17 years. The multimodal neuroimaging studies in female heterozygotes with OTCD also underscore that asymptomatic female heterozygotes with OTCD (e.g., proband) are not always asymptomatic. CONCLUSIONS: Analysis of Asx and Asx/Sym females with OTCD in this study suggests that future evidence-based management guidelines and/or a clinical risk score calculator for this cohort could be useful management tools to reduce morbidity and improve long-term quality of life.

Increased frequency of CHD1 deletions in prostate cancers of African American men is associated with rapid disease progression without inducing homologous recombination deficiency.

We analyzed genomic data derived from the prostate cancer of African and European American men in order to identify differences that may contribute to racial disparity of outcome and that could also define novel therapeutic strategies. In addition to analyzing patient derived next generation sequencing data, we performed FISH based confirmatory studies of Chromodomain helicase DNA-binding protein 1 (CHD1) loss on prostate cancer tissue microarrays. We created CRISPR edited, CHD1 deficient prostate cancer cell lines for genomic, drug sensitivity and functional homologous recombination (HR) activity analysis. We found that subclonal deletion of CHD1 is nearly three times as frequent in prostate tumors of African American men than in men of European ancestry and it associates with rapid disease progression. We further showed that CHD1 deletion is not associated with homologous recombination deficiency associated mutational signatures in prostate cancer. In prostate cancer cell line models CHD1 deletion did not induce HR deficiency as detected by RAD51 foci formation assay or mutational signatures, which was consistent with the moderate increase of olaparib sensitivity. CHD1 deficient prostate cancer cells, however, showed higher sensitivity to talazoparib. CHD1 loss may contribute to worse outcome of prostate cancer in African American men. A deeper understanding of the interaction between CHD1 loss and PARP inhibitor sensitivity will be needed to determine the optimal use of targeted agents such as talazoparib in the context of castration resistant prostate cancer.

Immunologic Assessment of Tumors from a Race-matched Military Cohort Identifies Mast Cell Depletion as a Marker of Prostate Cancer Progression.

Elucidating the cellular immune components underlying aggressive prostate cancer, especially among African American (AA) men who are disproportionately affected by this disease compared with Caucasian American (CA) men, will support more inclusive precision medicine treatment strategies. We aimed to evaluate which immune-related genes and cell types are differentially expressed in AA tumors and how immunobiology impacts prostate cancer progression. We purified nucleic acid from tumor biopsies, obtained following radical prostatectomy, from 51 patients (AA = 26, CA = 25). Gene expression was measured using the NanoString platform from which we estimated immune cell abundances and assessed differences between groups based on clinicopathologic data. Product-limit estimates determined associations with biochemical recurrence (BCR)-free and metastasis-free survival. DVL2 and KLRC2 were significantly upregulated in CA tumors and were also associated with worse disease progression. No significant differences in immune cell abundances by race were observed. Highly significant reductions in abundances of mast cells versus tumor-infiltrating lymphocytes (TIL) were found in men with high-grade pathologies and in men who later developed metastases. Low ratios of mast cells versus TILs were associated with worse BCR-free survival and metastasis-free survival. Although estimated immune cell abundances were not different by race, we identified genes involved in metabolism and natural killer cell functions that were differentially expressed between AA and CA tumors. Among the entire cohort, depletion of mast cells within prostatectomy tumors was characteristic of advanced disease and susceptibility to disease progression. Significance: Our findings demonstrate that there are immune-related genes and pathways that differ by race. Impaired intratumoral cellular immune composition, especially for TIL-normalized mast cells, may be vital in predicting and contributing to prostate cancer disease progression.

Prospective Long-term Health-related Quality of Life Outcomes After Surgery, Radiotherapy, or Active Surveillance for Localized Prostate Cancer.

Background: Localized prostate cancer (PCa) treatment is associated with reduced health-related quality of life (HRQoL). Current literature is limited by short-term follow-up. Objective: To prospectively evaluate the 5-yr HRQoL outcomes in men undergoing radical prostatectomy (RP), external beam radiotherapy (EBRT), or active surveillance (AS). Design setting and participants: We prospectively evaluated HRQoL in patients with low-risk/favorable intermediate-risk PCa enrolled in the Center for Prostate Disease Research multicenter database between 2007 and 2017. Intervention: Of 1012 patients included in the study, 252 (24.9%) underwent AS, 557 (55.0%) RP, and 203 (20.0%) EBRT. Patients complete the Expanded Prostate Cancer Index Composite and the 36-item Medical Outcomes Study Short Form at baseline and thereafter each year up to 5 yr after treatment. Outcome measurements and statistical analysis: Temporal changes in HRQoL were compared between treatments and were modeled using linear regression models adjusted for baseline HRQoL, demographic, and clinical characteristics. Results and limitations: RP showed the least irritative symptoms and worse incontinence in comparison with AS (p < 0.001 for both subdomains) or EBRT (p < 0.001 for both subdomains) at all time points. RP sexual domain score was worse than the scores of AS (mean difference 22.3 points, 95% confidence interval [CI] 10.5-27.8, p < 0.001) and EBRT (mean difference 16.9 points, 95% CI 12.5-20.3, p < 0.001) during years 1-3 and not different from that of EBRT (mean difference 2.9 points, 95% CI -4.8 to 8.3, p = 0.3) at years 4 and 5. Bowel function and bother were worse for EBRT than for AS (p < 0.001 for both subdomains) and RP (p < 0.001 for both subdomains) at all time points. During the 3-5-yr period, AS demonstrated the worst decline in all mental health domains (p < 0.001 in comparison with both EBRT and RP). Conclusions: RP results in worse long-term urinary function and incontinence, but in less irritative and obstructive symptoms than EBRT and AS. Sexual domain scores were least affected by AS, while RP shows similar scores to EBRT at long term. Long-term HRQoL changes are critical for advising patients. Patient summary: We evaluated long-term health-related quality of life (HRQoL) in a large US population treated for localized prostate cancer. HRQoL outcomes varied according to treatment modality and time. These changes should inform patients about their expected outcomes following treatment.

Five-year survival of patients with late-stage prostate cancer: comparison of the Military Health System and the U.S. general population.

BACKGROUND: While the 5-year survival rate for local and regional prostate cancer is nearly 100%, it decreases dramatically for advanced tumours. Accessibility to health care is an important factor for cancer prognosis. The U.S. Military Health System (MHS) provides universal health care to its beneficiaries, reducing financial barriers to medical care. However, whether the universal care translates into improved survival among patients with advanced prostate cancer in the MHS is unknown. In this study, we compared the MHS and the U.S. general population in survival of patients with advanced prostate cancer (stages III and IV). METHODS: The MHS patients (N = 5379) were identified from the Department of Defense's (DoD) Automated Central Tumor Registry (ACTUR). Patients in the U.S. general population (N = 21,516) were identified from the Surveillance, Epidemiology, and End Results (SEER) programme. The two populations were matched on age, race, and diagnosis year. RESULTS: The ACTUR patients exhibited longer 5-year survival than the matched SEER patients (HR = 0.74, 95% CI = 0.67-0.83), after adjustment for the potential confounders. The improved survival was observed for ages 50 years or older, both White patients and Black patients, all tumour stages and grades. This was also demonstrated despite the receipt of surgery or radiation treatment. CONCLUSIONS: MHS beneficiaries with advanced prostate cancer had longer survival than their counterparts in the U.S. general population.

The effect of race on treatment patterns and subsequent health-related quality of life outcomes in men undergoing treatment for localized prostate cancer.

INTRODUCTION: Racial differences in Health-Related Quality of Life (HRQoL) after treatment of prostate cancer (PCa) are not well studied. We compared treatment patterns and HRQoL in African American (AA) and non-AA men undergoing active surveillance (AS), radical prostatectomy (RP), or radiation (XRT). METHODS: Men diagnosed with PCa from 2007-2017 in the Center for Prostate Disease Research Database were identified. HRQoL was evaluated using Expanded PCa Index Composite and SF-36 Health Survey. RESULTS: In 1006 men with localized PCa, 223 (22.2%) were AA (mean follow up 5.2 yrs). AA men with low-risk disease were less likely to undergo AS (28.5 vs. 38.8%) and more likely to undergo XRT (22.3 vs. 10.6%) than non-AA men, p < 0.001. In intermediate-risk disease, AA received more XRT (43.0 vs. 26.9%) and less RP (50.5 vs 66.8%), p = 0.016. In all men, RP resulted in worse urinary function and sexual HRQoL compared to AS and XRT. Bowel HRQoL did not vary by treatment in AA men, however, in non-AA men, XRT resulted in worse bowel scores than AS and RP. HRQoL was then compared for each treatment modality. AA men had worse sexual bother (p = 0.024) after RP than non-AA men, No racial differences were found in urinary, bowel, hormonal, or SF-36 scores for men undergoing AS, RP or XRT. CONCLUSION: AA men are less often treated with AS for low-risk disease and are more likely to undergo XRT. AA men experience worse sexual bother after RP, however, the effect of XRT on bowel symptoms is worse in non-AA men.

Effect of the Family-Centered Advance Care Planning for Teens with Cancer Intervention on Sustainability of Congruence About End-of-Life Treatment Preferences: A Randomized Clinical Trial.

Importance: The effect of pediatric advance care planning (pACP) on the sustainability of end-of-life treatment preference congruence between adolescents with cancer and their families has not been examined. Objective: To evaluate the longitudinal efficacy of the Family-Centered Advance Care Planning for Teens with Cancer (FACE-TC) intervention to sustain adolescent-family congruence about end-of-life treatment preferences. Design, Setting, and Participants: This multisite, assessor-blinded, randomized clinical trial enrolled adolescents with cancer (aged 14-21 years) and their family members from 4 pediatric hospitals between July 16, 2016, and April 30, 2019. Participants were randomized 2:1 to FACE-TC (intervention group) or treatment as usual (control group) and underwent 5 follow-up visits over an 18-month postintervention period. Intention-to-treat analyses were conducted from March 9, 2021, to April 14, 2022. Exposures: Adolescent-family dyads randomized to the FACE-TC group received 3 weekly 60-minute sessions consisting of the discussion and/or completion of the Lyon Family-Centered Advance Care Planning Survey (session 1), Respecting Choices Next Steps pACP conversation (session 2), and Five Wishes advance directive (session 3). Dyads in the control group received treatment as usual. Both groups received pACP information. Main Outcomes and Measures: Congruence was measured by completion of the Statement of Treatment Preferences (a document that discusses 4 hypothetical clinical situations and treatment choices for each scenario: continue all treatments, stop all efforts to keep me alive, or unsure) after session 2 (time 1) and at 3 months (time 2), 6 months (time 3), 12 months (time 4), and 18 months (time 5) after intervention. The influence of FACE-TC on the trajectory of congruence over time was measured by longitudinal latent class analysis. Results: A total of 252 participants (126 adolescent-family dyads) were randomized. Adolescents (mean [SD] age, 17 [1.9] years) and family members (mean [SD] age, 46 [8.3] years) were predominantly female (72 [57%] and 104 [83%]) and White individuals (100 [79%] and 103 [82%]). There was an 83% (104 of 126) retention at the 18-month assessment. Two latent classes of congruence over time were identified: high-congruence latent class (69 of 116 [60%]) and low-congruence latent class (47 of 116 [41%]). The dyads in the FACE-TC group had a 3-fold odds of being in the high-congruence latent class (odds ratio [OR], 3.22; 95% CI, 1.09-9.57) compared with the control group. Statistically significant differences existed at 12 months (ß [SE] = 1.17 [0.55]; P = .03]) but not at 18 months (OR, 2.08; 95% CI, 0.92-4.69). In the high-congruence latent class, good agreement (agreement on 2 or 3 of 4 situations) increased over 12 months. White adolescents and families had significantly greater odds of congruence than a small population of American Indian or Alaska Native, Asian, Black or African American, Hispanic or Latino, or multiracial adolescents and families (OR, 3.97; 95% CI, 1.07-14.69). Conclusions and Relevance: Results of this trial showed that, for those who received the FACE-TC intervention, the families' knowledge of their adolescents' end-of-life treatment preferences was sustained for 1 year, suggesting yearly follow-up sessions. Race and ethnicity-based differences in the sustainability of this knowledge reflect a difference in the effect of the intervention and require further study.

An Intervention in Congruence for End-of-Life Treatment Preference: A Randomized Trial.

BACKGROUND AND OBJECTIVES: There is a gap in family knowledge of their adolescents' end-of-life (EOL) treatment preferences. We tested the efficacy of Family Centered Advance Care Planning for Teens with Cancer (FACE-TC) pediatric advance care planning (to increase congruence in EOL treatment preferences. METHODS: Adolescents with cancer/family dyads were randomized into a clinical trial from July 2016 to April 2019 at a 2:1 ratio: intervention (n = 83); control (n = 43) to either 3 weekly sessions of FACE-TC (Lyon Advance Care Planning Survey; Next Steps: Respecting Choices Interview; Five Wishes, advance directive) or treatment as usual (TAU). Statement of Treatment Preferences measured congruence. RESULTS: Adolescents' (n = 126) mean age was 16.9 years; 57% were female and 79% were White. FACE-TC dyads had greater overall agreement than TAU: high 34% vs 2%, moderate 52% vs 45%, low 14% vs 52%, and P < .0001. Significantly greater odds of congruence were found for FACE-TC dyads than TAU for 3 of 4 disease-specific scenarios: for example, "a long hospitalization with low chance of survival," 78% (57 of 73) vs 45% (19 of 42); odds ratio, 4.31 (95% confidence interval, 1.89-9.82). FACE-TC families were more likely to agree to stop some treatments. Intervention adolescents, 67% (48 of 73), wanted their families to do what is best at the time, whereas fewer TAU adolescents, 43% (18 of 42), gave families this leeway (P = .01). CONCLUSIONS: High-quality pediatric advance care planning enabled families to know their adolescents' EOL treatment preferences.

Focal p53 protein expression and lymphovascular invasion in primary prostate tumors predict metastatic progression.

TP53 is one of the most frequently altered genes in prostate cancer. The precise assessment of its focal alterations in primary tumors by immunohistochemistry (IHC) has significantly enhanced its prognosis. p53 protein expression and lymphovascular invasion (LVI) were evaluated for predicting metastatic progression by IHC staining of representative whole-mounted prostate sections from a cohort of 189 radical prostatectomy patients with up to 20 years of clinical follow-up. Kaplan-Meier survival curves were used to examine time to distant metastasis (DM) as a function of p53 expression and LVI status. TP53 targeted sequencing was performed in ten tumors with the highest expression of p53 staining. Nearly half (49.8%) of prostate tumors examined showed focal p53 expression while 26.6% showed evidence of LVI. p53(+) tumors had higher pathologic T stage, Grade Group, Nuclear Grade, and more frequent LVI. p53 expression of > 5% and LVI, individually and jointly, are associated with poorer DM-free survival. TP53 mutations were detected in seven of ten tumors sequenced. Four tumors with the highest p53 expression harbored likely pathogenic or pathogenic mutations. High levels of p53 expression suggest the likelihood of pathogenic TP53 alterations and, together with LVI status, could enhance early prognostication of prostate cancer progression.

Prospective quality of life in men choosing open vs. robotic radical prostatectomy: long-term results from a racially diverse multi-institutional database.

PURPOSE: To compare 5-year health-related quality of life (HRQoL) outcomes between prostate cancer (CaP) patients who underwent robotic-assisted laparoscopic radical prostatectomy (RALP) versus open radical retropubic prostatectomy (RRP) and assess for racial disparities between Caucasian American (CA) and African American (AA) men undergoing surgery. METHODS: A prospective cohort study of HRQoL data was conducted on patients diagnosed with CaP from 2007 to 2017 and enrolled in the Center for Prostate Disease Research (CPDR) Multicenter National Database. Using the EPIC and SF-36 instruments, changes in urinary, sexual, bowel, and hormonal domains, as well as physical and mental component summary scores were compared across surgery type (RALP versus RRP) at pre-treatment ("baseline"), and annually for 5 years. We further compared HRQoL outcomes in CA and AA men undergoing surgery. Longitudinal HRQoL patterns were modeled using generalized estimating equations (GEE), adjusting for baseline HRQoL and other characteristics. RESULTS: 448 CaP patients (22% AA) met study inclusion criteria, 66% underwent RALP and 34% underwent RRP. At baseline, HRQoL domains were comparable across treatment group (RALP vs. RRP). In the adjusted low-risk cohort, there were only three time points that met a statistically significant HRQoL difference in EPIC scores between RALP and RRP. Urinary function score during year 4 of follow-up showed a 7.5 (95% CI 3.1-11.9, P = 0.01) points difference in favor of RRP. Bowel bother scores favored RRP in year 1 with a difference of 3.1 (95% CI 0.7-5.4, P = 0.04) points, and in year 5 with a difference of 3.8 (95% CI 1.1-6.4, P = 0.03) points. In the intermediate/high-risk cohort, there were no statistically significant differences in any of the domain scores between RALP and RRP during follow-up. CONCLUSIONS: The robotic and open approach to radical prostatectomy led to comparable HRQoL outcomes at a follow-up length of 60 months. No HRQoL racial disparities were found between AA and CA men during long-term follow-up.

The intersectionality of gender and poverty on symptom suffering among adolescents with cancer.

BACKGROUND: To determine if the intersectionality of gender and poverty is associated with health disparities among adolescents with cancer. We hypothesized unobserved latent classes of patients exist with respect to cancer-related symptoms; and class classification varies by gender-poverty combinations. PROCEDURE: Cross-sectional data were collected among adolescents with cancer and families (N = 126 dyads) at four tertiary pediatric hospitals. Adolescents were aged 14-21 years, English speaking, cancer diagnosis, not developmentally delayed, psychotic, homicidal, suicidal, or severely depressed. Latent class analysis and multinomial logit models were used for analysis. Patient-Reported Outcomes Measurement Information System (PROMIS) pediatric symptom measures, Short forms, evaluated anxiety, depressive symptoms, pain interference, and fatigue. Family-reported household income used 2016 Federal Poverty Level (FPL) guidelines. RESULTS: Three distinct groups of patients were identified using PROMIS symptom patterns: High Distress-25%; High Physical/Low Psychological Distress-14%; and Low Distress-62%. Female adolescents living in households with incomes at or below the 2016 FPL had 30 times the odds of being classified in the High Distress class (higher probabilities of experiencing anxiety, depressive symptoms, pain interference, and fatigue) compared to those in the High Physical/Low Psychological Distress class (female and poverty: AOR = 30.27, 95% CI 1.23, 735.10), and this was statistically significant (ß = 3.41, 95% CI 0.21, 6.60; p = .04) but not compared to those in Low Distress. CONCLUSION: Adolescent females with cancer with households in poverty had significantly greater odds of experiencing high symptom distress, compared to those with high physical but low psychological distress. More comprehensive screening and intervention, as needed, may decrease disparities.

Timing of Androgen Deprivation Treatment for Men with Biochemical Recurrent Prostate Cancer in the Context of Novel Therapies.

PURPOSE: There were 3 recent U.S. Food and Drug Administration approvals for drugs to be used in nonmetastatic castration resistant prostate cancer, a state that arises from the unproven start of continuous androgen deprivation therapy (ADT) for biochemical recurrent prostate cancer (BCR), before metastatic disease is evident. This report examines the outcome of men with BCR who defer ADT until time of metastasis. MATERIALS AND METHODS: Retrospective review of men diagnosed with clinically localized prostate cancer who underwent radical prostatectomy at Johns Hopkins Hospital and Walter Reed National Military Medical Center and developed BCR with a prostate specific antigen doubling time of not more than 10 months (806 patients). The primary end points were metastasis-free survival and overall survival from time of local treatment among men who delayed ADT until time of metastasis. RESULTS: The median metastasis-free survival of men with BCR and a prostate specific antigen doubling time <6 months and 10 months who delay ADT until metastasis is 144 months (95% CI 48-not reached) and 192 months (95% CI 72-not reached), respectively, with a median overall survival of 168 months (95% CI 96-276 months) and 204 months (95% CI 120-276), respectively. CONCLUSIONS: Metastasis-free survival and overall survival of men with BCR who delay hormone therapy is long. This underscores the need to reevaluate when to start primary ADT in this patient population.

Early Inflammatory Markers are Associated With Inadequate Post-Induction Infliximab Trough in Pediatric Crohn's Disease.

OBJECTIVES: In pediatric Crohn's disease, infliximab trough concentrations after standard weight-based induction therapy are commonly below 7 µg/mL. Clinical treatment outcomes are associated with post-induction infliximab trough concentration. Markers of inflammation are associated with low infliximab concentrations during maintenance dosing. We sought to determine if early markers of disease activity are associated with inadequate post-induction infliximab trough concentrations in pediatric Crohn's disease. METHODS: We performed a retrospective single-center case-control study of pediatric Crohn's disease patients to assess the association between baseline and week-2 biomarkers (albumin, C-reactive protein, and erythrocyte sedimentation rate) and inadequate post-induction infliximab trough concentration (<7 µg/mL) in patients treated with standard 5 mg/kg dosing. Baseline and week-2 biomarker values were coded as dichotomous variables at clinically useful thresholds. Univariable logistic regression was used to calculate odds ratios of developing an inadequate infliximab trough concentration for each threshold, as well as thresholds in combination. RESULTS: Fifty-five patients were evaluated. Early biomarker thresholds significantly associated with inadequate post-induction infliximab trough concentrations included baseline C-reactive protein >1 mg/dL (odds ratio [OR] 4.58; 95% confidence interval [CI] 1.24--17.01), both baseline C-reactive protein >0.5 mg/dL and albumin <3.5 g/dL (OR 8.31; 95% CI 1.99--34.63), and week-2 C-reactive protein >0.5 mg/dL or albumin <3.5 mg/dL or erythrocyte sedimentation rate >25 mm/hour (OR 11.08; 95% CI 2.14--57.22). CONCLUSIONS: Routine baseline and week-2 markers of disease activity at clinically useful thresholds were associated with inadequate post-induction infliximab trough concentration in pediatric Crohn's disease patients receiving standard weight-based induction dosing.

Mindful Mentors: Is a Longitudinal Mind-Body Skills Training Pilot Program Feasible for Pediatric Cardiology Staff?

BACKGROUND: Stress and burnout among medical professionals are common and costly, placing professionals, organizations, and patients at risk. OBJECTIVES: To determine feasibility and acceptability of a longitudinal mind-body skills training initiative to help staff decrease stress and burnout, improve well-being, and empower them to utilize basic mindfulness methods with coworkers, patients, and families. METHODS: Prospective cohort, mixed methods approach. Nurses, doctors, technicians, social workers, child life specialists were eligible to participate. The 12-month curriculum consisted of 16 hours of intensive education/practice over 2 days, with training in mindfulness skills, self-compassion, nonviolent communication, overcoming barriers to practice, and mindful listening/speaking, followed by monthly 1 hour booster/debriefing sessions. RESULTS: A total of 37 staff participated (RN = 18, MD = 5, Technician = 6, Social Worker = 3, Child life = 3, others = 2) in the initial training, and 24 (65%) completed the 3- and 12-month follow-up surveys. Compared with pretraining scores, there were significant improvements 3 to 12 months after the initial training in stress (P < .0001), distress (P ≤ .04), anxiety (P = .01), self-efficacy in providing non-drug therapies (P < .0001), mindfulness (P = .002), burnout (P < .0001), and confidence in providing compassionate care (P < .0001). In addition, 25 (67%) participants initiated projects incorporating what they learned into staff/patient wellness activities. CONCLUSION: This longitudinal pilot program was feasible and was associated with improvements in measures of psychological well-being over the 12-month intervention. The innovative approach of training participants to teach basic techniques to coworkers and other staff can increase the impact of this program beyond any individual participant. Future research will investigate the aspects of implementation and potential effects on patient care and experience.

Normal right and left ventricular volumes prospectively obtained from cardiovascular magnetic resonance in awake, healthy, 0- 12 year old children.

INTRODUCTION: Pediatric z scores are necessary to describe size and structure of the heart in growing children, however, development of an accurate z score calculator requires robust normal datasets, which are difficult to obtain with cardiovascular magnetic resonance (CMR) in children. Motion-corrected (MOCO) cines from re-binned, reconstructed real-time cine offer a free-breathing, rapid acquisition resulting in cines with high spatial and temporal resolution. In combination with child-friendly positioning and entertainment, MOCO cine technique allows for rapid cine volumetry in patients of all ages without sedation. Thus, our aim was to prospectively enroll normal infants and children birth-12 years for creation and validation of a z score calculator describing normal right ventricular (RV) and left ventricular (LV) size. METHODS: With IRB approval and consent/assent, 149 normal children successfully underwent a brief noncontrast CMR on a 1.5 T scanner including MOCO cines in the short axis, and RV and LV volumes were measured. 20% of scans were re-measured for interobserver variability analyses. A general linear modeling (GLM) framework was employed to identify and properly represent the relationship between CMR-based assessments and anthropometric data. Scatter plots of model fit and Akaike's information criteria (AIC) results were used to guide the choice among alternative models. RESULTS: A total of 149 subjects aged 22 days-12 years (average 5.1 ± 3.6 years), with body surface area (BSA) range 0.21-1.63 m2 (average 0.8 ± 0.35 m2) were scanned. All ICC values were > 95%, reflecting excellent agreement between raters. The model that provided the best fit of volume measure to the data included BSA with higher order effects and gender as independent variables. Compared with earlier z score models, there is important additional growth inflection in early toddlerhood with similar z score prediction in later childhood. CONCLUSIONS: Free-breathing, MOCO cines allow for accurate, reliable RV and LV volumetry in a wide range of infants and children while awake. Equations predicting fit between LV and RV normal values and BSA are reported herein for purposes of creating z scores. TRIAL REGISTRATION: clinicaltrials.gov NCT02892136, Registered 7/21/2016.

Neurodevelopmental Abnormalities in Children With In Utero Zika Virus Exposure Without Congenital Zika Syndrome.

Importance: The number of children who were born to mothers with Zika virus (ZIKV) infection during pregnancy but who did not have apparent disability at birth is large, warranting the study of the risk for neurodevelopmental impairment in this population without congenital Zika syndrome (CZS). Objective: To investigate whether infants without CZS but who were exposed to ZIKV in utero have normal neurodevelopmental outcomes until 18 months of age. Design, Setting, and Participants: This cohort study prospectively enrolled a group of pregnant women with ZIKV in Atlántico Department, Colombia, and in Washington, DC. With this cohort, we performed a longitudinal study of infant neurodevelopment. Infants born between August 1, 2016, and November 30, 2017, were included if they were live born, had normal fetal brain findings on magnetic resonance imaging and ultrasonography, were normocephalic at birth, and had normal examination results without clinical evidence of CZS. Seventy-seven infants born in Colombia, but 0 infants born in the United States, met the inclusion criteria. Exposures: Prenatal ZIKV exposure. Main Outcomes and Measures: Infant development was assessed by the Warner Initial Developmental Evaluation of Adaptive and Functional Skills (WIDEA) and the Alberta Infant Motor Scale (AIMS) at 1 or 2 time points between 4 and 18 months of age. The WIDEA and AIMS scores were converted to z scores compared with normative samples. Longitudinal mixed-effects regression models based on bootstrap resampling methods estimated scores over time, accounting for gestational age at maternal ZIKV infection and infant age at assessment. Results were presented as slope coefficients with 2-tailed P values based on z statistics that tested whether the coefficient differed from 0 (no change). Results: Of the 77 Colombian infants included in this cohort study, 70 (91%) had no CZS and underwent neurodevelopmental assessments. Forty infants (57%) were evaluated between 4 and 8 months of age at a median (interquartile range [IQR]) age of 5.9 (5.3-6.5) months, and 60 (86%) underwent assessment between 9 and 18 months of age at a median (IQR) age of 13.0 (11.2-16.4) months. The WIDEA total score (coefficients: age = -0.227 vs age2 = 0.006; P < .003) and self-care domain score (coefficients: age = -0.238 vs age2 = 0.01; P < .008) showed curvilinear associations with age. Other domain scores showed linear declines with increasing age based on coefficients for communication (-0.036; P = .001), social cognition (-0.10; P < .001), and mobility (-0.14; P < .001). The AIMS scores were similar to the normative sample over time (95% CI, -0.107 to 0.037; P = .34). Nineteen of 57 infants (33%) who underwent postnatal cranial ultrasonography had a nonspecific, mild finding. No difference was found in the decline of WIDEA z scores between infants with and those without cranial ultrasonography findings except for a complex interactive relationship involving the social cognition domain (P < .049). The AIMS z scores were lower in infants with nonspecific cranial ultrasonography findings (-0.49; P = .07). Conclusions and Relevance: This study found that infants with in utero ZIKV exposure without CZS appeared at risk for abnormal neurodevelopmental outcomes in the first 18 months of life. Long-term neurodevelopmental surveillance of all newborns with ZIKV exposure is recommended.

Radioactive iodine therapy for pediatric Graves' disease: a single-center experience over a 10-year period.

Introduction Only about 30% of pediatric patients with Graves' hyperthyroidism achieve remission with medical therapy, and therefore radioactive iodine (RAI) therapy is often used as a definitive treatment. Although the goal of RAI is permanent hypothyroidism, this is not consistently achieved. We conducted a chart review to determine the factors associated with the success of RAI. We also tried to determine optimal follow-up post RAI and if there was an optimal L-thyroxine dose that would normalize the hypothyroid state quickly. Methods This is a retrospective chart review of Graves' patients who underwent RAI between 2008 and 2017. We included age, sex, time from diagnosis, thyroid gland size, total dose of I-131 and dose in µCi/g of thyroid tissue. Patients were grouped based on outcome and analyzed using univariate and multivariate logistic regression. Follow-up thyroid levels post RAI and after starting l-thyroxine were analyzed. Results There were 78 ablations including six repeat ablations. Seventy-three percent became hypothyroid, 23% remained overtly or subclinically hyperthyroid, and 4% were euthyroid. Smaller thyroid size (36.5 vs. 47.4 g; p = 0.037) and higher dose of I-131 (242 vs. 212 µCi/g thyroid tissue; p = 0.013) were associated with a higher likelihood of hypothyroidism. Most patients remained hyperthyroid at 1 month post RAI, but by 3 months the majority became hypothyroid. There was no clear L-thyroxine dose that normalized hypothyroidism quickly. Conclusions An I-131 dose close to 250 µCi/g of thyroid tissue has a higher likelihood of achieving hypothyroidism. Testing at 2-3 months after RAI is most helpful to confirm response to RAI.

Parental Conflict, Regret, and Short-term Impact on Quality of Life in Tracheostomy Decision-Making.

OBJECTIVES: The prevalence of tracheostomy-dependence in critically ill children is increasing in the United States. We do not know the impact of this decision on parental outcomes. We aimed to determine the prevalence of decisional conflict and regret and explore the impact on quality of life among parents considering tracheostomy placement for their child. SUBJECTS: Parents facing tracheostomy decision for their child. DESIGN: Prospective, mixed-methods longitudinal study. SETTING: PICU, cardiac ICU, and neonatal ICU of a single quaternary medical center. INTERVENTIONS: None. MEASUREMENTS AND MAIN RESULTS: Parents completed a decisional conflict survey at the time of tracheostomy decision and decisional regret and quality of life surveys at 2 weeks and 3 months after the decision regarding tracheostomy placement was made. We enrolled 39 parents, of which 25 completed surveys at all three time points. Thirty-five of 39 (89.7%) reported at least some decisional conflict, most commonly from feeling uninformed and pressured to make a decision. At 2 weeks, 13 of 25 parents (52%) reported regret, which increased to 18 of 25 participants (72%) at 3 months. Regret stemmed from feeling uninformed, ill-chosen timing of placement, and perceptions of inadequate medical care. At 2 weeks, the quality of life score was in the mid-range, 78.8 (SD 13.8) and decreased to 75.5 (SD 14.2) at 3 months. Quality of life was impacted by the overwhelming medical care and complexity of caring for a child with a tracheostomy, financial burden, and effect on parent's psychosocial health. CONCLUSIONS: The decision to pursue tracheostomy among parents of critically ill children is fraught with conflict with worsening regret and quality of life over time. Strategies to reduce contributing factors may improve parental outcomes after this life-changing decision.

An endogenous DNA adduct as a prognostic biomarker for hepatocarcinogenesis and its prevention by Theaphenon E in mice.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-related deaths worldwide, mainly because of its poor prognosis. A valid mechanism-based prognostic biomarker is urgently needed. γ-hydroxy-1,N2 -propanodeoxyguanosine (γ-OHPdG) is an endogenously formed mutagenic DNA adduct derived from lipid peroxidation. We examined the relationship of γ-OHPdG with hepatocarcinogenesis in two animal models and its potential role as a prognostic biomarker for recurrence in HCC patients. Bioassays were conducted in xeroderma pigmentosum group A knockout mice and diethylnitrosamine-injected mice, both prone to HCC development. γ-OHPdG levels in the livers of these animals were determined. The effects of antioxidant treatments on γ-OHPdG and hepatocarcinogenesis were examined. Using two independent sets of HCC specimens from patients, we examined the relationship between γ-OHPdG and survival or recurrence-free survival. γ-OHPdG levels in liver DNA showed an age-dependent increase and consistently correlated with HCC development in all three animal models. Theaphenon E treatment significantly decreased γ-OHPdG levels in the liver DNA of xeroderma pigmentosum group A knockout mice and remarkably reduced HCC incidence in these mice to 14% from 100% in the controls. It also effectively inhibited HCC development in the diethylnitrosamine-injected mice. Using clinical samples from two groups of patients, our study revealed that higher levels of γ-OHPdG are strongly associated with low survival (P < 0.0001) and low recurrence-free survival (P = 0.007). CONCLUSION: These results support γ-OHPdG as a mechanism-based, biologically relevant biomarker for predicting the risk of HCC and its recurrence. (Hepatology 2018;67:159-170).

Latent Rheumatic Heart Disease: Identifying the Children at Highest Risk of Unfavorable Outcome.

BACKGROUND: Screening echocardiography has emerged as a potentially powerful tool for early diagnosis of rheumatic heart disease (RHD). The utility of screening echocardiography hinges on the rate of RHD progression and the ability of penicillin prophylaxis to improve outcome. We report the longitudinal outcomes of a cohort of children with latent RHD and identify risk factors for unfavorable outcomes. METHODS: This was a prospective natural history study conducted under the Ugandan RHD registry. Children with latent RHD and ≥1 year of follow-up were included. All echocardiograms were re-reviewed by experts (2012 World Heart Federation criteria) for inclusion and evidence of change. Bi- and multivariable logistic regression, Kaplan-Meier analysis, and Cox proportional hazards models, as well, were developed to search for risk factors for unfavorable outcome and compare progression-free survival between those treated and not treated with penicillin. Propensity and other matching methods with sensitivity analysis were implemented for the evaluation of the penicillin effect. RESULTS: Blinded review confirmed 227 cases of latent RHD: 164 borderline and 63 definite (42 mild, 21 moderate/severe). Median age at diagnosis was 12 years and median follow-up was 2.3 years (interquartile range, 2.0-2.9). Penicillin prophylaxis was prescribed in 49.3% with overall adherence of 84.7%. Of children with moderate-to-severe definite RHD, 47.6% had echocardiographic progression (including 2 deaths), and 9.5% had echocardiographic regression. Children with mild definite and borderline RHD showed 26% and 9.8% echocardiographic progression and 45.2% and 46.3% echocardiographic improvement, respectively. Of those with mild definite RHD or borderline RHD, more advanced disease category, younger age, and morphological mitral valve features were risk factors for an unfavorable outcome. CONCLUSIONS: Latent RHD is a heterogeneous diagnosis with variable disease outcomes. Children with moderate to severe latent RHD have poor outcomes. Children with both borderline and mild definite RHD are at substantial risk of progression. Although long-term outcome remains unclear, the initial change in latent RHD may be evident during the first 1 to 2 years following diagnosis. Natural history data are inherently limited, and a randomized clinical trial is needed to definitively determine the impact of penicillin prophylaxis on the trajectory of latent RHD.
