Frequent CHD1 deletions in prostate cancers of African American men is associated with rapid disease progression.

We analyzed genomic data from the prostate cancer of African- and European American men to identify differences contributing to racial disparity of outcome. We also performed FISH-based studies of Chromodomain helicase DNA-binding protein 1 (CHD1) loss on prostate cancer tissue microarrays. We created CHD1-deficient prostate cancer cell lines for genomic, drug sensitivity and functional homologous recombination (HR) activity analysis.

A selective CutMix approach improves generalizability of deep learning-based grading and risk assessment of prostate cancer.

The Gleason score is an important predictor of prognosis in prostate cancer. However, its subjective nature can result in over- or under-grading. Our objective was to train an artificial intelligence (AI)-based algorithm to grade prostate cancer in specimens from patients who underwent radical prostatectomy (RP) and to assess the correlation of AI-estimated proportions of different Gleason patterns with biochemical recurrence-free survival (RFS), metastasis-free survival (MFS), and overall survival (OS).

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 () loss on prostate cancer tissue microarrays. We created CRISPR edited, deficient prostate cancer cell lines for genomic, drug sensitivity and functional homologous recombination (HR) activity analysis.

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.

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

Unlabelled: 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).

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

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.

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).

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

Unlabelled: 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,N -propanodeoxyguanosine (γ-OHPdG) is an endogenously formed mutagenic DNA adduct derived from lipid peroxidation.

Intratumoral CD3 and CD8 T-cell Densities Associated with Relapse-Free Survival in HCC.

Immune cells that infiltrate a tumor may be a prognostic factor for patients who have had surgically resected hepatocellular carcinoma (HCC). The density of intratumoral total (CD3(+)) and cytotoxic (CD8(+)) T lymphocytes was measured in the tumor interior and in the invasive margin of 65 stage I to IV HCC tissue specimens from a single cohort. Immune cell density in the interior and margin was converted to a binary score (0, low; 1, high), which was correlated with tumor recurrence and relapse-free survival (RFS).

Somatic mutation of GRIN2A in malignant melanoma results in loss of tumor suppressor activity via aberrant NMDAR complex formation.

The ionotropic glutamate receptors (N-methyl-D-aspartate receptors (NMDARs)) are composed of large complexes of multi-protein subunits creating ion channels in the cell plasma membranes that allow for influx or efflux of mono- or divalent cations (e.g., Ca(2+)) important for synaptic transmissions, cellular migration, and survival.

Somatic mutations in MAP3K5 attenuate its proapoptotic function in melanoma through increased binding to thioredoxin.

Patients with advanced metastatic melanoma have poor prognosis and the genetics underlying its pathogenesis are poorly understood. High-throughput sequencing has allowed comprehensive discovery of somatic mutations in cancer samples. Here, on analysis of our whole-genome and whole-exome sequencing data of 29 melanoma samples, we identified several genes that harbor recurrent nonsynonymous mutations.
